Description
- 1. Technical Field
- The present invention relates generally to a heating and cooling apparatus. More specifically, the invention relates to an apparatus used to heat or cool a desired area. In particular, the present invention relates to an apparatus having a housing with a fan and a heating element, wherein the heating element is positioned between the fan and the inner surface of the housing configured to turn on/off through the use of logic.
- 2. Background Information
- Mechanical fans are types of machines used to create flow within a fluid, typically air. Typically, axial-flow fans have blades that move air in a direction parallel to a motor drive shaft about which the blades rotate. Centrifugal fans have blades arranged to move air in a direction generally perpendicular to the intake air flow. Mixed-Flow fans move air both perpendicularly and parallel to the intake air flow.
- Electrically powered mechanical fans used to move air in a desired space, typically the home, are well known and have been employed for at least a century. Over the years, improvements and variations have come and gone to the electric fan, namely, variations that alter the number of blades, the configuration of the blades, the size of the blades, the pitch angle of the blades, the drive motors, or the fan housings. Yet, even with these variations mechanical fans still have drawbacks and further, they often fail to employ modern technology.
- Therefore, a need continues to exist for an improvement to the mechanical fan. The present invention address addresses this and other issues.
- An embodiment of the present invention provides a fan housed within a housing having a heating element attached inside the housing. The heating element and a motor may be in electrical communication with a temperature control system, a motion detector, or both. Logic controls the control system and the motion detector to cause the heating element or the motor to turn on/off when a programmed threshold has been reached. The present invention may heat a desired space when the heating elements are turned on and the motor is rotating the fan. The present invention may also cool a desired spaced when the heating elements are turned off but the motor is still rotating the fan.
- In one aspect, the invention may provide a heating and cooling apparatus comprising: a fan comprising a plurality of blades extending between a support plate and a retaining collar; a housing configured to receive the fan; and at least one heating element attached to the housing.
- In another aspect, the invention may provide a heating and cooling device comprising: a mixed flow fan to move fluid as the mixed flow fan rotates about an axis, the fan includes a plurality of blades having generally vertically extending exit edges to move fluid in a horizontal direction; a fan housing to receive the mixed flow fan, the housing including an annular sidewall, wherein the sidewall is spaced apart and generally parallel to the vertical exit edges, defining therebetween a heater element gap; and at least one heating element mounted to the fan housing and positioned in the heater element gap.

- With primary reference to
FIG. 5 , asecond embodiment 210 depicts a plurality ofexits ports 200 inhousing 14 configured differently that the first embodiment.Exit ports 200 are U-shaped and formed in sidewall 272 adjacent the top.Ports 200 are defined by a bottomhorizontal edge 202 extending between first and secondvertical edges Ports 200 have an open top side when viewed from the side and the topannular plate 70 is not attached. The spaced apart relationship of plurality ofports 200 definescolumns 210 between the firstvertical edge 206 of one port and the secondvertical edge 208 of the next adjacent port.Columns 210 generally have a vertical distance greater than a width distance. - In accordance with one aspect of the present invention as herein described above, heating and
cooling apparatus apparatus apparatus housing 14 disinfects air moving through system through the application of air purifying properties. - In operation, heating and
cooling apparatus 10 is assembled by insertingfan 12 intocavity 74 ofhousing 14.Motor 18 is secured to fan 12 bydrive shaft 116 extending throughplate aperture 48 and secured toboss 50.Motor 18 is electrically connected topower source 17. Motor has on/off drive functions to causedrive shaft 116 to rotate. When turned on, motor rotatesfan 12 aboutaxis 13. The fan rotation causes air to be drawn in from the bottom 22 in the direction of arrow A (FIG. 1 ) into entrance ports defined by theblades 24.Blades 24 move air out of the fan exiting through ports 100 (FIGS. 1-3 ) or 200 (FIG. 5 ) fromhousing 14 in the direction of arrow B (FIG. 1 ). -
Heating elements 16 are electrically connected topower source 17.Element 16 may turned on/off. When turned on,element resistor 114 converts electricity into heat through the process of Joule heating. Electric current runs throughresistor 114 encountering a resistance, thus resulting in heating of theelement 16.Heating elements 16 may be turned on independently of whether thefan 12 is rotating. When bothheating elements 16 andfan 12 are turned on, thefan 12 will blow warmed air out exit ports 110 (FIGS. 1-3 ) or 210 (FIG. 5 ). Alternatively, heating elements may be connected to an alternate power source. -
Temperature control system 19 is electrically connected toheating elements 16 andmotor 18. Temperature control system may contain a thermostat (not shown) and be programmed to a desired set point temperature. For example, the set point temperature of thearea surrounding apparatus 10 may be seventy-two degrees Fahrenheit. Temperature control system monitors the surrounding temperature via the thermostat. If the surrounding area temperature is hotter than the set point temperature,control system 19, through the use of logic, may turn onmotor 18 causingfan 12 to rotate in order to cool the surrounding area. If the surrounding area temperature is colder than the set point temperature,control system 19, through the use of logic, may turn on theheating elements 16, with or without turning on themotor 18, to heat the surrounding area. -
Motion detector 19 a (FIG. 1 ) or sensor may be configured in electrical communication withapparatus 10. Motion detector may monitor a desired area for movement. If movement is detected, motion detector, through the use of logic, may cause either one or both of theheating elements 16 ormotor 18 to turn on. Motion detector may further monitor the desired area to detect an absence of movement. In the absence of movement, motion detector, through the use of logic, may cause either one or both of theheating elements 16 ormotor 18 to turn off.Motion detector 19 a may be mounted to housing or may be mounted in electrical communication but physically separated fromapparatus 10 as shown inFIG. 1 electrically connected tosystem 19. An exemplary motion sensor ordetector 19 a that may be used in combination with thepresent invention 10 is commercially known under the name Vacancy Motion Detector, Model #R02-IPV15-1LM, manufactured by Leviton Manufacturing Company, Inc. of Melville, N.Y., clearly other commercially known motion sensor may be substituted. - When the motor is turned on air is drawn into the
fan 12 from the bottom 22 in a generally vertical manner relative toaxis 13 along directional arrow A (FIG. 1 ). Asblades 24 turn, air is forced out the blade exit ports generally perpendicular, i.e., radially outward, relative toaxis 13, along directional arrow B (FIG. 1 ). Stated otherwise, the air exiting thefan 12 is approximately perpendicular, i.e. moving radially, to the air entering thefan 12. As air exits thefan 12 in a generally radial manner and moves towards exiting the housing through the ports,sidewall 72 may contain disinfecting properties to cleanse the air.Sidewall 72 may contain, be integrally formed with, or be coated with solutions or compounds to reduce bacteria or viruses in the air, thus purifying the air. - In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.
- Moreover, the description and illustration of the preferred embodiment of the invention are an example and the invention is not limited to the exact details shown or described.
