Abstract

Water (200) is jetted from a jetting port (13) provided on the end of an intra-nozzle water channel (12). A plate spring (14) in which a plate spring (first restricting member) (14A) and a plate spring (second restricting member) (14B) are united is mounted on a nozzle base (11). At the edge of the upper plate spring (14A) on both sides of the jetting direction (I) of the water (200), projections (14E, 14F) that protrude downward are respectively formed. By the projections (14E, 14F) coming in contact with the lower plate spring (14B), a gap of an interval (D) is formed between the projection (14E) and the projection (14F) and between the plate spring (14A) and the plate spring (14B). Because said gap is formed regardless of the pressure of the water (200) jetted from the jetting port (13), water (200) is jetted from said gap even when water pressure is low. Consequently, it is possible to stably perform operations to increase jetting angle, etc. even when water (liquid) pressure is low.

Description

Nozzle for washing machine and washing machine

The present invention relates to a nozzle for a washing machine used for jetting a liquid in a washing machine that pressurizes and jets a liquid such as water, and a structure of a washing machine using the nozzle.

2. Description of the Related Art As a washing machine that is used for washing by pressurizing and spraying water with a pump, there is used a system in which water stored in a tank is sucked up by a pump and pressurized and ejected from a washing nozzle. As the pump, an engine-driven pump or an electric pump is used, but an pump using an electric pump is particularly preferably used because the apparatus can be downsized and has high silence.

The configuration of an example of such a washing machine 100 is shown in FIG. In this figure, water (liquid) is introduced into the cleaning machine main body 110 from a water suction port (liquid supply port) 111 provided in the cleaning machine main body 110 in the cleaning machine 100. The introduced water is pressurized to a high pressure by an electric pump (not shown) that operates when a switch 112 provided in the washing machine main body 110 is turned on, and is discharged from the water outlet 113. One end of a high pressure hose 120 is connected to the water outlet 113, and a gun 140 having a cleaning machine nozzle 130 at the tip is connected to the other end of the high pressure hose 120. The operator can perform a cleaning operation by injecting high-pressure water from the cleaning machine nozzle 130 by directing the cleaning nozzle 130 toward the object to be cleaned by holding the gun 140 and pulling the trigger 141. .

In order to supply water to the water inlet 111, a water supply hose 150 that can be bent is used. In this case, a filter 151 for removing dust and sucking only water is attached to one end of the water supply hose 150, and the filter 151 is submerged in the water 200 stored in the water tank 160. In particular, when the washing machine 100 is used outdoors, the water tank 160 is often used in this manner because the water tap is not always in the vicinity.

In this case, Patent Document 1 discloses a configuration for adjusting the pressure of water sprayed from the cleaning machine nozzle 130. At this time, it is possible not only to change the pressure but also to adjust the discharge angle or discharge width of the jetted water. Here, the discharge angle is the spread angle of the jetted water, and the discharge width is the width of the jetted water. When the discharge angle or discharge width is small, high-pressure water can be concentrated on a narrow area, and when the discharge angle or discharge width is large, the pressure decreases, but water can be applied over a wide area. it can. For this reason, the cleaning operation can be performed efficiently by appropriately switching the discharge angle and the discharge width.

An example of the mechanism of the cleaning nozzle 130 for adjusting the water discharge angle and discharge width (hereinafter referred to as discharge angle) will be described. First, a case where the water discharge angle is small will be described. Here, the discharge angle etc. in a horizontal plane shall be adjusted. FIG. 7A is a cross-sectional view in the vertical direction (direction perpendicular to the direction in which the discharge angle and the like are adjusted) showing the configuration of the washing machine nozzle 130 in this state. In this cleaning machine nozzle 130, the water that has passed through the nozzle water passage 132 provided in the nozzle base 131 is ejected from a jet outlet 133 having an inner diameter of, for example, about 0.75 mm in the ejection direction I in FIG. Along the right side (one side).

Plate springs

134A and 134B are provided at the upper and lower portions of the right side of the jet outlet 133 so as to face each other across the jet direction I. The

leaf springs

134A and 134B are both parallel to the horizontal plane in the state of FIG. A plate spring support portion 135A is fixed to the upper side of the plate spring 134A and a lower side of the

plate spring

134B, and 135B is fixed to protrude downward.

Further, an outer cylinder 136 is attached to the nozzle base 131 so as to cover the plate spring 134A, the plate spring 134B, and the like from the outside when viewed from the ejection direction I. The outer cylinder 136 is rotatable about the ejection direction I with respect to the nozzle base 131, and the inner surface of the outer cylinder 136 is in contact with the leaf

spring support portions

135A and 135B. However, the inner diameter of the outer cylinder 136 is not uniform, and a portion with a smaller inner diameter and a larger portion are formed. In the state of FIG. 7, the leaf

spring support portions

135A and 135B are in contact with the portion with the larger inner diameter of the outer cylinder 136. ing. The

plate springs

134A and 134B are actually integrated, and the integrated plate spring 134 is attached to the nozzle base 131 to form the configuration shown in FIG.

FIGS. 7B and 7C schematically show the forms of the

leaf springs

134A and 134B and the water 200 to be ejected in the vertical direction (b) and the horizontal direction (c), respectively. Although the

leaf springs

134A and 134B are located on the downstream side of the water ejected from the ejection port 133, the

leaf springs

134A and 134B do not contact the ejected water 200 in the state of FIG. For this reason, the water 200 is ejected at a small discharge angle determined by the inner diameter of the ejection port 133.

On the other hand, FIG. 8 shows the form of the cleaning machine nozzle 130 and the water 200 to be ejected in the same manner as FIG. 7 when the discharge angle or the like is increased. This state is realized by rotating the outer cylinder 136 with respect to the nozzle base 131 from the state of FIG. In this case, since the leaf spring support

portions

135A and 135B are in contact with the small inner diameter portion of the outer cylinder 136, the leaf spring 134A is on the lower side and the leaf spring 134B is on the upper side, as shown in FIG. Respectively. For this reason, the tip of the leaf spring 134A and the tip of the leaf spring 134B (one end on one side) are in contact with each other, and the path of the water 200 is blocked when viewed from the jet outlet 133 side. However, when the high-pressure water 200 is ejected in this state, a gap is formed between the leaf spring 134A and the leaf spring 134B by the water pressure of the water 200, and the water 200 is ejected through this gap. At this time, the gap becomes smaller than the inner diameter of the jet outlet 133, and the water 200 is ejected after spreading over the entire gap. For this reason, as shown in FIG. 8C, in the horizontal direction, the water 200 is ejected with a wide discharge angle and discharge width corresponding to the width of the

leaf springs

134A and 134B.

When using the cleaning machine 100, the gun 140 equipped with the cleaning machine nozzle 130 is often wet with water. Therefore, an electrical switch may not be used to adjust the discharge angle and the like. It is preferable from the viewpoint of reliability and the like. The above configuration is particularly preferably used because only a simple mechanical mechanism is used for adjusting the discharge angle and the like.

JP 2005-313008 A

In the above configuration, in the case of FIG. 8 in which the discharge angle and the like are increased, a gap is formed between the leaf spring 134A and the leaf spring 134B by the water pressure of the water 200 ejected from the ejection port 133, and from this gap Water 200 spouts out. For example, when a commercial AC power source or the like is used as the power source for the washing machine main body 110, the output of the pump can be sufficiently increased, so that the water pressure of the water 200 ejected from the ejection port 133 can be sufficiently increased. The gap between the leaf spring 134A and the leaf spring 134B can be formed stably. However, in this case, the washing machine 100 can be used only in a place where commercial AC power can be supplied. For this reason, a battery with a low power supply voltage or low output may be used as a power source for the cleaning machine body 110. In such a case, it is difficult to sufficiently increase the water pressure of the jetted water 200, or the water pressure may be lowered depending on the remaining battery level.

In such a case, it may be difficult to form a gap between the leaf spring 134A and the leaf spring 134B due to water pressure, and a large state such as a discharge angle as shown in FIGS. Therefore, it becomes difficult to stably eject the water 200. At this time, the influence of the variation in the gap state for each product due to the manufacturing variation of the

leaf springs

134A and 134B increases, and the discharge angle, discharge width, and discharge direction of the water 200 may vary greatly from product to product. It was.

For this reason, there has been a demand for a washing machine that can stably perform an operation of increasing the discharge angle even when the pressure of water (liquid) is low.

It is a figure which shows the structure at the time of adjusting the discharge angle etc. largely in the conventional washing machine nozzle.

A cleaning machine nozzle according to an embodiment of the present invention will be described. The cleaning machine nozzle 10 can be used in the same manner as the cleaning machine nozzle 130 shown in FIGS. 6 to 8. At this time, the water discharge angle and discharge width (discharge angle, etc.) can be adjusted similarly. it can. However, the operation of increasing the discharge angle or the like is stably performed regardless of the water pressure.

FIG. 1 shows a mode in which the discharge angle or the like is adjusted to be small in this nozzle 10 for a washing machine, and FIG. 2 shows a mode in which the discharge angle or the like is adjusted to be large, similarly to FIGS. In this cleaning machine nozzle 10, similarly to the cleaning machine nozzle 130, the nozzle internal water channel 12 is formed in the nozzle base 11, and the water 200 is supplied from the spout 13 provided at the end of the nozzle internal water channel 12. Is ejected. Further, in the state of FIG. 1A, a plate spring 14 in which a plate spring (first regulating member) 14 </ b> A and a plate spring (second regulating member) 14 </ b> B that are both horizontal are integrated is mounted on the nozzle base 11. . A plate spring support (regulation member support) 15A is mounted on the upper side of the plate spring 14A, and a plate spring support (control member support) 15B is mounted on the lower side of the plate spring 14B. The leaf

spring support portions

15A and 15B are urged outward by the

leaf springs

14A and 14B (the leaf spring support portion 15A is on the upper side and the leaf spring support portion 15B is on the lower side). It is always in contact with the inner surface of the outer cylinder 16 attached to. 1A shows a state in which the

leaf springs

14A and 14B are most separated from each other, and FIG. 1B shows a state in which the

leaf springs

14A and 14B are closest to each other.

3 (a) and 3 (b) are side views of the configurations shown in FIGS. 1 (a) and 2 (a) as viewed from the right side (the side on which water 200 is ejected in the ejection direction I: one side). It is. Similar to the cleaning nozzle 130 described above, the inner diameter of the outer cylinder 16 is not uniform, and in the state of FIG. 1 (FIG. 3A), the large inner diameter portion of the outer cylinder 16 corresponds to the leaf

spring support portions

15A and 15B. In contact with each other, in the state of FIG. 2 (FIG. 3B), the portion having a small inner diameter of the outer cylinder 16 contacts the leaf

spring support portions

15A and 15B. Between the portion with a large inner diameter and the portion with a small inner diameter in the outer cylinder 16, a gently curved shape is formed so that the leaf

spring support portions

15A and 15B can slide. By rotating the outer cylinder 16 clockwise from the state shown in FIG. 3A to the state shown in FIG. 3B, the state shown in FIG. 1 (the state where the discharge angle is small) is changed to the state shown in FIG. Switch to a large state). That is, by restricting the liquid discharge by the

leaf springs

14A and 14B, the discharge angle and the discharge width can be adjusted (restricted). The

leaf springs

14A and 14B function as regulating members.

The shape of the leaf spring 14 used here is different from the leaf spring 134 used in the cleaning nozzle 130. FIG. 4 is a top view (a), a front view (b), and a side view (c) of the leaf spring 14. Here, the front view (b) is a view seen from the direction corresponding to FIGS. 1 (a) and 2 (a), and the side view (c) is a view seen from the direction corresponding to FIG. is there. 4 shows the shape of the leaf spring 14 in a state where no force is applied from the outside, the

leaf springs

14A and 14B are more open than in FIG. The plate spring 14A and the plate spring 14B are joined by a left connecting portion 14C, and a through hole 14D through which the jet port 13 passes is formed in the connecting portion 14C. For this reason, this leaf | plate spring 14 can be mounted | worn and fixed to the nozzle base | substrate 11 with the form of FIG.

Here, as shown in FIG. 4 (c), the lower side (the side of the leaf spring 14B) is located on both sides of the ejection direction I of the water 200 at the end of the upper leaf spring (first regulating member) 14A. ) Projecting

portions

14E and 14F (void forming members) are formed. 4A and 4B, the lower leaf spring (second regulating member) 14B is longer along the ejection direction I than the upper leaf spring (first regulating member) 14A. Is formed. For this reason, as shown in FIG. 2B, when the end of the leaf spring 14A moves downward and the end of the leaf spring 14B moves upward, the

protrusions

14E and 14F and the leaf spring 14B comes into contact with certainty. Thus, the leaf spring 14A and the leaf spring 14B are asymmetric in the vertical direction. Note that the

protrusions

14E and 14F shown in FIG. 4A are depressions formed when the protrusions formed on the upper surface of the leaf spring are formed by pressing as shown in FIG. 5B.

5 (a) and 5 (b) are enlarged views of the region X in FIG. 4 (b) and the region Y in FIG. 4 (c), and the shape of the protrusion 14E (14F) is shown. . FIG. 5C is an enlarged view showing a state where the protrusion 14F is in contact with the lower leaf spring 14B in a region Z in FIG. 3B. When the

protrusions

14E and 14F are in contact with the lower leaf spring 14B, in the state shown in FIG. 3B, the distance D between the protrusion 14E and the protrusion 14F is between the leaf spring 14A and the leaf spring 14B. Voids are formed. Since this void is formed regardless of the water pressure of the water 200 ejected from the ejection port 13, the water 200 is ejected from this void even when the water pressure is low. For this reason, if the interval D is made sufficiently smaller than the inner diameter of the ejection port 13, the water 200 is ejected after spreading over the entire gap, and ejected at a large ejection angle or the like as shown in FIG. . The height of the

protrusions

14E and 14F is such that the distance D is sufficiently smaller than the inner diameter of the jet port 13, for example, about 0.1 to 0.3 mm when the inner diameter of the jet port 13 is about 0.75 mm. Is set. When the water pressure of the water 200 becomes high, the

leaf springs

14A and 14B are expanded by the pressure as in the conventional cleaning machine nozzle 130, so that the distance D is further larger than the state of FIG. Become. In the above configuration, by providing the

protrusions

14E and 14F on the leaf spring 14A, the minimum value of the interval D is ensured, so that the water 200 can be ejected at a large discharge angle or the like even when the water pressure is low. Further, when the water pressure is low, the gap defined as the interval D is always maintained. Therefore, if the heights of the

protrusions

14E and 14F are appropriately controlled, the variation in the product in the water discharge state is small. Become. Further, the other leaf spring 14B not provided with the protrusions is made longer along the ejection direction I than the one leaf spring 14A provided with the

protrusions

14E and 14F. Since it is ejected after hitting the spring 14B, the water 200 can be ejected stably at a large discharge angle or the like even if there are variations in the product of the protrusions.

In the case of FIG. 1 in which the discharge angle and the like are adjusted to be small, the distance between the leaf spring (first regulating member) 14A and the leaf spring (second regulating member) 14B becomes large, regardless of the presence or absence of the

protrusions

14E and 14F. The water 200 is ejected without contacting the

leaf springs

14A and 14B. The situation in this case is not different from FIG.

The plate spring 14 can be easily formed by sheet metal processing (press processing) a single plate spring member (elastic metal thin plate). The elastic modulus of the elastic metal plate and the lengths of the

leaf springs

14A and 14B along the direction in which the water 200 is ejected can be set in consideration of the distance D when the water pressure increases and the state of the water 200 ejection. it can. When the elastic coefficient is increased and the

leaf springs

14A and 14B are lengthened, the distance D does not change greatly even if the water pressure increases. Further, the widths of the

leaf springs

14A and 14B perpendicular to the jet direction of the water 200 can be set in consideration of the discharge width. The

protrusions

14E and 14F having the shape shown in FIG. 4 can be easily formed by bending the leaf spring 14A.

However, as long as said operation | movement is possible, the structure of a 1st control member, a 2nd control member, and a projection part is arbitrary. For example, the first restricting member and the second restricting member do not need to be integrated, and at least the whole need not be formed of a leaf spring member. It is also possible to form the protrusion and the first restricting member from different materials and join them together. However, by integrating the first restricting member, the second restricting member, and the projecting portion with the leaf spring member, it is possible to increase the accuracy of the positional relationship between them and to manufacture them at low cost. Furthermore, by making the leaf spring in which these are integrated into the shape of FIG. 4, the integrated structure can be easily mounted with high accuracy around the jet nozzle. Thereby, a highly accurate nozzle for a washing machine can be obtained at low cost.

In the above example, the protrusions (gap forming members) are provided on both end sides in the direction perpendicular to the ejection direction I in the first restriction member, but the first restriction member and the second restriction member The number and the installation position are arbitrary as long as the effect that the gaps can be reliably formed is obtained. Further, it is not necessary to provide the first restricting member integrally, and a gap may be formed between the restricting members as a separate body. However, since the protrusions themselves become obstacles to the discharged water, it is preferable that the number of the protrusions is small, and it is preferable to install the protrusions in a place where the water does not become an obstacle. For this reason, the above-described configuration in which one protrusion is provided on each end of the first restricting member in the direction perpendicular to the ejection direction I is particularly preferable. Further, by forming the protrusion (gap forming member) integrally with the first regulating member, it can be easily formed by press working.

When the washing machine nozzle 10 is used in the washing machine 100 shown in FIG. 6, even when the output of the pump used in the washing machine main body 110 is low, the operation of increasing the water discharge angle or the like is stabilized. Can be done. For this reason, said nozzle 10 for washing machines is especially effective, when a high output pump is not used, for example, when a battery (storage battery) is used as a power supply which drives a pump. However, even when the output of the pump is large and the water pressure is high, the minimum value of the distance D between the first restricting member and the second restricting member is ensured. It is the same that the variation from product to product is reduced. For this reason, it is clear that the washing machine nozzle 10 is effective regardless of the power source of the pump used for ejecting water. For example, the nozzle 10 is driven by a pump or an engine driven by a commercial AC power source. Even when a pump is used, it is effective. It is also clear that the above configuration is effective even when the liquid to be ejected is other than water.
