- first and second surfaces 11a, 11b when there is only one bent portion 113 formed between and linking the first and second surfaces 11a, 11b, they are two adjacent and non-coplanar surfaces; alternatively, if there are more than one bent portions 113, the first and second surfaces 11a, 11b, are two opposite and non-coplanar surfaces.
- the first inlet 111 is formed in the first surface 11a
- the first outlet 112 is formed in the second surface 11b.

- the auxiliary fan 43 is disposed in the first branch space 41a of the housing 41, so that the auxiliary fan 43 aligns with the first air-guiding space 21 through the first opening 411a.
- the auxiliary fan 43 of the control module 4 if the driving circuit or control circuit is disposed inside the first branch space 41a, the heat generated by the driving circuit or control circuit can be dispelled rapidly.
- the auxiliary fan 43 corresponds with the first air-guiding space 21, the auxiliary fan 43 can provide functions similar to those of fan 3, such as helping performance of air convection.
- the auxiliary fan 43 may be disposed in the second branch space 41b if the fan 3 is settled in the first air-guiding space 21, so that the auxiliary fan 43 aligns with the second air-guiding space 22 through the second opening 411b. Accordingly, the auxiliary fan 43 not only rapidly dispels the heat generated by the driving circuit or control circuit if the driving circuit or control circuit is disposed inside the second branch space 41b, but also helps performance of air convection.
- At least one of the fan 3 and the auxiliary fan 43 electrically connects with a rotation control circuit 5, which is adapted to control the fan 3 or auxiliary fan 43 to rotate in a forward direction or a reverse direction. Therefore, when the rotation control circuit 5 controls the fan 3 or the auxiliary fan 43 to rotate in a first direction, the airflow induced by the fan 3 or the auxiliary fan 43 goes in a way shown by the arrow "I" in Figs. 3 or 6 for air convection; when the rotation control circuit 5 controls the fan 3 or the auxiliary fan 43 to rotate in a second direction, the airflow induced by the fan 3 or the auxiliary fan 43 goes in a reverse way of the arrow "I" in Figs.
- the rotation control circuit 5 may decide the timing to change the rotational direction of the fan 3 or auxiliary fan 43.
- the fan 3 or auxiliary fan 43 may be cyclically controlled to rotate in the first direction for a convection time, such as 30-60 minutes, and then be reversely controlled to rotate in the second direction for a cleaning time, such as 10-20 seconds.
- the cleaning time can be arranged to be prior to the convection time.
- the disclosed air exchange device may further include a cover 6 in the external space "S1," connecting with the air-guiding tube 1, and covering the first end 11 of the air-guiding tube 1, with the cover 6 having an opening 61.
- the air-guiding tube 1 does not expose to external factors in the external space "S1,” such as humidity, wind, and dust, and the look of the air exchange device is also improved.
- the cover 6 comprises an inner wall spaced from the first inlet 111 and the first outlet 112 for the air in the external space "S1" to smoothly enter the air-guiding tube 1 via the opening 61 and the inlet 111, or for the air in the air-guiding tube 1 to be expelled to the external space "S1" via the outlet 112 and the opening 61.
- the opening 61 faces downwards preferably, so as to relieve the accumulation of dust.
- the disclosed air exchange device has advantages such as high efficiency in cooling and air-convection, long lifetime, and high degree in convenience of usage.
- the internal space "S2" can get ride of the noise pollution due to the operational sound of the fan 3, especially when most parts of the air-guiding tube 1 and the fan 3 are outside the internal space "S2.”
- the control module 4 connecting with the second end 12 of the air-guiding tube 1 and corresponding to the second inlet 121 and second outlet 122, the heat generated by the control module 4 can be dissipated when airflows are induced by the fan 3. Therefore, there is no need to additionally arrange any fin or fan for cooling the control module 4, and thus the cost of the air exchange device is limited.
Abstract
Description
- The present invention generally relates to an air exchange device and, more particularly, to an air exchange device for exchange of air inside and outside of a room.
- Referring to
Fig. 1 , a conventionalair exchange device 9 settled in a building's wall or the housing of an electrical product is shown. Taking awall 91 of a building as an example, thewall 91 is formed to separate an internal space and an external space. Thewall 91 includes aninlet 911 and anoutlet 912, and bothinlet 911 andoutlet 912 communicate the internal and external spaces, with afan 92 settled across theinlet 911 and anotherfan 92 settled across theoutlet 912. Therefore, when thefans 92 operates, air in the external space enters the internal space via theinlet 911, and air in the internal space is expelled via theoutlet 912. Accordingly, theair exchange device 9 can exchange air inside and outside the building cyclically. - However, in order to settle this
air exchange device 9, two through holes serving as theinlet 911 andoutlet 912 are necessary, and this dual hole arrangement may result in decreasing of structural strength of thewall 91. Moreover, the necessary area on the surface of thewall 91 for these two through holes is so big that the use of the surface is thus largely limited. Besides, since a side of thefans 92 is exposed to the external space via theinlet 911 or theoutlet 912, the heat and humidity of the external space may easily damage thefans 92, and thus lower the lifetime of thefans 92. - Furthermore, the
fans 92 are conventionally connected with control modules composed by driving circuits, control circuits or other electronic elements, so that thefans 92 can be driven to inwardly or outwardly guide the air. However, since the control modules tend to generate a large amount of heat during the operations, an additional cooling sink or cooling device is required to lower the working temperature of said modules. This will increase the cost of theair exchange device 9. - Additionally, since the
fans 92 are simply connected to thewall 91 without any sound-insulating design, the operational noise of thefans 92 can easily transmit to the environment as noise pollution. - What is needed is an air exchange device unnecessary to be mounted on a divider via two openings of this divider but still able to provide a desirable performance in air convection about the divider, to maintain the structural strength of the divider, and to provide an area of the surface of the divider large enough for any further use.
- Another need is an air exchange device able to perform the air convection as well as to cool a control module.
- A still another need is an air exchange device able to lower or shade the noise made during operation of the fan.
- A further need is an air exchange device capable of increasing the structural strength of the divider without having to drill through holes on the divider.

- In the following contents, a "divider" is a structure adapted to separate an external space and an internal space. For example, when a housing of an electronic product serves as the divider, the external space is the space outside the housing, and the internal space is the space inside the housing. As another example, when a wall of a building serves as the divider, the external space is the space outside the building, and the internal space is the space inside the building. Furthermore, in the following contents, a "control module" is a module including electronic elements, such as driving circuit, control circuit, or user interface, which is capable of fan driving and control, for controlling the operation of a disclosed air exchange device. Besides, according to user's need, the control module can also include various electronic members with function of lighting, alarm, or air-filtering, such as light emitter, alarm, and negative air ions generator.
- Referring to
Figs. 2 and3 , the air exchange device of the preferred embodiment of this disclosure is mounted on a divider "D," with a first side of the divider "D" exposing to an external space "S1" and a second side of the divider "D," opposite to the first side, exposing to an internal space "S2." The divider "D" has a through hole "D1" extending from the first side to the second side. This air exchange device includes an air-guidingtube 1, apartition 2, afan 3, and acontrol module 4. The air-guidingtube 1 is arranged in and extending through the through hole "D1." Thepartition 2 and thefan 3 are settled inside the air-guidingtube 1. Thecontrol module 4 electrically connects with thefan 3. - The air-guiding
tube 1 can be a tube with any kind of sectional shape, and the one shown inFig. 2 is a tube with round sectional shape. The air-guidingtube 1 has afirst end 11 and asecond end 12 opposite to thefirst end 11. For guiding air to enter or exit the air-guidingtube 1, thefirst end 11 has afirst inlet 111 and afirst outlet 112, and thesecond end 12 has asecond inlet 121 and asecond outlet 122. - The
partition 2 settled inside the air-guidingtube 1 can be integrally formed within the air-guidingtube 1 or detachably connected with the air-guidingtube 1. Specifically, thepartition 2 divides the room inside the air-guidingtube 1 into two independent spaces: a first air-guidingspace 21 and a second air-guidingspace 22. In this embodiment, thepartition 2 includes afirst section 2a, asecond section 2b and an inclined connectingsection 2c, which links the first andsecond sections section 2c, airflow can be smoothly guided from thefirst section 2a to thesecond section 2b. - The
fan 3 settled inside the air-guidingtube 1 is adapted to generate airflow. The position of thefan 3 is not limited as long as the airflow generated by thefan 3 can finally enter or exit the air-guidingtube 1. For example, thefan 3 can be arranged in the first air-guidingspace 21 or second air-guidingspace 22; specifically, thefan 3 can be arranged at thefirst inlet 111, thefirst outlet 112, thesecond inlet 121, or thesecond outlet 122. Therefore, it is not necessary to largely increase the size of the air-guidingtube 1 for containing thefan 3. Alternatively, there can also be anotherfan 3 settled inside the air-guidingtube 1 as shown inFigs. 2 and3 , and the twofans 3 are arranged in the first and second air-guidingspaces fan 3 settled inside the air-guidingtube 1, the air-guidingtube 1 can provide a certain degree of sound insulation to lower the noise pollution around the air-guidingtube 1 when thefan 3 operates. Particularly, the efficiency of sound insulation can be further improved if a layer of sound-insulating material is applied to the inner surface of the air-guidingtube 1. Thefan 3 has a structure designed to be driven by a motor, such as axial fan, centrifugal fan, blower, or exchange fan. - The
control module 4 connects with at least one of the first andsecond ends tube 1 integrally or detachably, and thecontrol module 4 also electrically connects with and operates thefan 3. Preferably, thecontrol module 4 connects with thesecond end 12 and is disposed in the internal space "S2," so that the repair and maintenance processes of thecontrol module 4 can be easily performed when the divider "D" is a wall of a building. Thecontrol module 4 is preferably in a position where at least one of thesecond inlet 121 andsecond outlet 122 faces, so that the heat generated by thecontrol module 4 can be easily dispelled when the airflow driven by thefan 3 enters or exits the air-guidingtube 1. In this embodiment, thecontrol module 4 has ahousing 41. Thehousing 41 has anopening 411, anauxiliary outlet 412 and anauxiliary inlet 413, with thehousing 41 connecting with thesecond end 12 by an edge defining theopening 411. Theopening 411 communicates with thesecond inlet 121 andsecond outlet 122. Aboard 42 is disposed inside thehousing 41 and across theopening 411, so as to divide the inner room of thehousing 41 into afirst branch space 41 a and asecond branch space 41b, and also to divide theopening 411 into afirst opening 411a and asecond opening 411b. Specifically, thefirst branch space 41a communicates with thefirst opening 411a and theauxiliary outlet 412; and thesecond branch space 41b communicates with thesecond opening 411b and theauxiliary inlet 413. Besides, thefirst opening 411a faces thesecond outlet 122, and thesecond opening 411b faces thesecond inlet 121. With the above arrangement, when a driving circuit or control circuit of thefan 3 is disposed in thefirst branch space 41a or thesecond branch space 41b and electrically connects with thefan 3, the heat generated by this circuit can be dissipated by the airflow passing through thefirst branch space 41a or thesecond branch space 41b. Furthermore, an electronic member with function of lighting, alarm, or air-filtering can also be arranged inside thefirst branch space 41a or thesecond branch space 41b. The electronic member is adapted to provide said function of lighting, alarm, or air-filtering, therefore, the electronic member may be a light emitter, an alarm, or a negative air ions generator. - Referring to
Fig. 3 , in use of the disclosed air exchange device, only one hole, that is, the through hole "D1" in the divider "D" is necessary. With the air-guidingtube 1 arranged in and extending through the through hole "D1," the airflow from the external space "S1" passes through thefirst inlet 111, the first air-guidingspace 21, thesecond outlet 122, thefirst section 411 a, thefirst branch space 41 a, and theauxiliary outlet 412 sequentially, so as to enter the internal space "S2." On the other hand, a reverse airflow from the internal space "S2" passes through theauxiliary inlet 413, thesecond branch space 41b, thesecond opening 411b, thesecond inlet 121, the second air-guidingspace 22, and thefirst outlet 112 sequentially, so as to be expelled to the external space "S1." In this way, the disclosed air exchange device can be functioned for air convection. - Referring to
Figs. 3 and4 now, preferably, the axial length of the air-guidingtube 1 is able to be adjusted. In order to implement the above idea, the air-guidingtube 1 may further include asleeve 13 moveably mounted on thefirst end 11. Thesleeve 13 independently includes afirst room 131 and asecond room 132 inside, and twoapertures 133 are formed in the wall of thesleeve 13 and communicate with the first andsecond rooms first room 131 communicates with the first air-guidingspace 21 and thesecond room 132 communicates with the second air-guidingspace 22. Specifically, thefirst room 131 andsecond room 132 serve as extensions of the first air-guidingspace 21 and second air-guidingspace 22, and theapertures 133 respectively serve as inlet and outlet of the air-guidingtube 1. As a result, referring to the arrow shown inFig. 4 , with the shift of thesleeve 13 in an axial direction of the air-guidingtube 1, positions of the inlet and outlet toward the external space "S1," which are theapertures 133 now, can be adjusted according to need. - Additionally, referring to
Figs. 2 and3 again, positions of thefirst inlet 111,first outlet 112,second inlet 121, andsecond outlet 122 are not limited. In this embodiment, thefirst inlet 111 andfirst outlet 112 face in the same direction. Alternatively, in order to provide different performance in air convection, as shown inFig. 5 , thefirst end 11 in the external space "S1" includes afirst surface 11a and asecond surface 11b, which are non-coplanar surfaces with at least onebent portion 113 formed between the first andsecond surfaces bent portion 113 formed between and linking the first andsecond surfaces bent portions 113, the first andsecond surfaces first inlet 111 is formed in thefirst surface 11a, and thefirst outlet 112 is formed in thesecond surface 11b. With the above arrangement, thefirst inlet 111 and thefirst outlet 112 face in different directions due to thebent portion 113 between the first andsecond surfaces tube 1 and the other airflow expelled thereby do not disturb each other. Preferably, thefirst surface 11a is perpendicular to thesecond surface 11b, so that the airflow may enter the air-guidingtube 1 via thefirst inlet 111 in a direction perpendicular to the axial direction of the air-guidingtube 1, and the other airflow may exit the air-guidingtube 1 via thefirst outlet 112 in a direction parallel to the axial direction of the air-guidingtube 1. Therefore, an improved performance of air convection is thus provided since airflow disturbance is efficiently avoided. Moreover, at least one of thefirst inlet 111,first outlet 112,auxiliary outlet 412, andauxiliary inlet 413, especially theauxiliary outlet 412 orauxiliary inlet 413, may have afilter 14 to avoid unwanted object such as dust or insects entering the air-guidingtube 1. When thefilter 14 is arranged at theauxiliary outlet 412 orauxiliary inlet 413, thefilter 14 is inside the internal space "S2" and may provide a preferable filtering performance. Besides, maintenance or replacement of thefilter 14 in the internal space "S2" can be easily performed when the divider "D" is a wall of a building. - Referring to
Fig. 6 now, when thefan 3 is settled inside the second air-guidingspace 22, thecontrol module 4 may further include anauxiliary fan 43 aligning with the first air-guidingspace 21. Specifically, theauxiliary fan 43 is disposed in thefirst branch space 41a of thehousing 41, so that theauxiliary fan 43 aligns with the first air-guidingspace 21 through thefirst opening 411a. By theauxiliary fan 43 of thecontrol module 4, if the driving circuit or control circuit is disposed inside thefirst branch space 41a, the heat generated by the driving circuit or control circuit can be dispelled rapidly. Furthermore, since theauxiliary fan 43 corresponds with the first air-guidingspace 21, theauxiliary fan 43 can provide functions similar to those offan 3, such as helping performance of air convection. Alternatively, theauxiliary fan 43 may be disposed in thesecond branch space 41b if thefan 3 is settled in the first air-guidingspace 21, so that theauxiliary fan 43 aligns with the second air-guidingspace 22 through thesecond opening 411b. Accordingly, theauxiliary fan 43 not only rapidly dispels the heat generated by the driving circuit or control circuit if the driving circuit or control circuit is disposed inside thesecond branch space 41b, but also helps performance of air convection. - Referring to
Fig. 7 , at least one of thefan 3 and theauxiliary fan 43 electrically connects with arotation control circuit 5, which is adapted to control thefan 3 orauxiliary fan 43 to rotate in a forward direction or a reverse direction. Therefore, when therotation control circuit 5 controls thefan 3 or theauxiliary fan 43 to rotate in a first direction, the airflow induced by thefan 3 or theauxiliary fan 43 goes in a way shown by the arrow "I" inFigs. 3 or6 for air convection; when therotation control circuit 5 controls thefan 3 or theauxiliary fan 43 to rotate in a second direction, the airflow induced by thefan 3 or theauxiliary fan 43 goes in a reverse way of the arrow "I" inFigs. 3 or6 for expelling the dust from inside the air-guidingtube 1 to prevent thefirst inlet 111 from being blocked by the accumulated dust. As such, the dust will not accumulate in the air-guidingtube 1 and hinder the air from entering the air-guidingtube 1, thereby maintaining an ideal performance of air convection. Specifically, therotation control circuit 5 may decide the timing to change the rotational direction of thefan 3 orauxiliary fan 43. For example, thefan 3 orauxiliary fan 43 may be cyclically controlled to rotate in the first direction for a convection time, such as 30-60 minutes, and then be reversely controlled to rotate in the second direction for a cleaning time, such as 10-20 seconds. Alternatively, the cleaning time can be arranged to be prior to the convection time. - Referring to
Fig.8 , the disclosed air exchange device may further include acover 6 in the external space "S1," connecting with the air-guidingtube 1, and covering thefirst end 11 of the air-guidingtube 1, with thecover 6 having anopening 61. With thiscover 6, the air-guidingtube 1 does not expose to external factors in the external space "S1," such as humidity, wind, and dust, and the look of the air exchange device is also improved. Specifically, thecover 6 comprises an inner wall spaced from thefirst inlet 111 and thefirst outlet 112 for the air in the external space "S1" to smoothly enter the air-guidingtube 1 via theopening 61 and theinlet 111, or for the air in the air-guidingtube 1 to be expelled to the external space "S1" via theoutlet 112 and theopening 61. Besides, when the divider "D" is a lateral wall of a building or a lateral side of a housing, theopening 61 faces downwards preferably, so as to relieve the accumulation of dust. Furthermore, there can also be anotherfilter 14 mounted in theopening 61 to avoid unwanted object entering the air-guidingtube 1. - In sum, with the above illustrated air exchange device, for air convection between the external space "S1" and the internal space "S2," only the single through hole "D1" " has to be set in the divider "D" for arrangement of this air exchange device. Therefore, the structural strength of the divider "D" is maintained, and the necessary amount of area of the divider "D" is also significantly limited. Moreover, the area of the air exchange device exposed to the external space "S1" is small, and thus damages caused by heat or humidity can be efficiently avoided. As a result, the disclosed air exchange device has advantages such as high efficiency in cooling and air-convection, long lifetime, and high degree in convenience of usage.
- Additionally, since the
fan 3 is settled inside the air-guidingtube 1, the internal space "S2" can get ride of the noise pollution due to the operational sound of thefan 3, especially when most parts of the air-guidingtube 1 and thefan 3 are outside the internal space "S2." Besides, with thecontrol module 4 connecting with thesecond end 12 of the air-guidingtube 1 and corresponding to thesecond inlet 121 andsecond outlet 122, the heat generated by thecontrol module 4 can be dissipated when airflows are induced by thefan 3. Therefore, there is no need to additionally arrange any fin or fan for cooling thecontrol module 4, and thus the cost of the air exchange device is limited. - Although the invention has been described in detail with reference to its presently preferable embodiments, it will be understood by one of ordinary skill in the art that various modifications can be made without departing from the spirit and the scope of the invention, as set forth in the appended claims.
