Description

Hand dryer

The present invention relates to a hand dryer that allows a user to dry hands wet with water after hand washing in hand washing in a restroom, a washroom, a hand washing place, and the like.

As a conventional hand dryer, for example, Patent Document 1 discloses a drying processing space in which a hand can be inserted and removed, a jet outlet that blows out high-speed air, and a water receiver that collects water droplets blown off by a high-speed air flow from the jet outlet. Are described.

Further, for example, Patent Document 2 includes a drying processing space in which a hand can be inserted and removed, a jet outlet that blows out a high-speed air flow, and a water receiving unit that collects water droplets blown off by the high-speed air flow from the jet outlet. At the start of operation, position the water catcher in the direction of the high-speed air flow that blows out from the jet outlet and position the water catcher in the direction of the high-speed air flow that blows out from the jet outlet over time. A hand dryer is described which changes the temperature. In this hand dryer, most of the water droplets adhering to the hand are blown off by the high-speed air flow in the first drying process starting from the start of operation, and the moisture on the surface of the hand is evaporated in the second drying process. In the first drying process, there is a water receiving portion at a position on the extension of the direction of the high-speed air flow blown from the jet outlet, and water droplets blown from the hand are received by the water receiving portion. Further, in the second drying process, there are almost no water droplets blown off from the hand and only the water that is wet on the surface of the hand is evaporated, so that it is not necessary to receive water in the water receiving portion. Therefore, in the second drying process, the position of the water outlet or the water receiving portion is changed so that the water receiving portion is not positioned on the extension of the direction of the high speed air flow from the outlet, and the high speed air flow and water from the outlet are changed. The generation of noise was greatly reduced by not directly colliding with the receiving part.

Japanese Patent Laying-Open No. 2004-290529 (paragraph “0017”, FIGS. 2 and 5) JP 2004-321485 A (“Claim 1”, paragraphs “0012” to “0013”, FIG. 1)

However, in the conventional hand dryer described in Patent Document 1, since there is a water receiving portion in the direction of the high-speed air flow that blows out from the jet outlet, the air flow that did not hit the hand hits the water receiving portion with its wind speed not attenuated much. There was a problem that noise was generated.

Also, in the conventional hand dryer described in Patent Document 2, in the first drying process from the start of operation, on the extension of the direction of the high-speed air flow from the jet outlet in order to receive water droplets blown from the hand. Since the water receiving part is located, similarly to Patent Document 1, there is a problem that the wind speed of the high-speed air flow that did not hit the hand hits the water receiving part without being attenuated so much that noise is generated.

The present invention has been made to solve the above-described problems, and receives water droplets peeled off from the hand by the air flow blown from the jet outlet at the water receiving portion and the air flow blown from the jet outlet.

A water receiving part is provided, and the water receiving part and the jet outlet do not face each other while the air flow is blown from the jet outlet.

According to a second aspect of the present invention, the hand dryer receives a water outlet blown from a hand in the drying processing space by a jet outlet that blows out an air flow toward the drying processing space and an air flow blown from the jet outlet. The water receiving portion is provided, and the water receiving portion is not positioned on the extension of the blowing direction of the jet port while the air flow is blown from the jet port.

According to a third aspect of the present invention, there is provided a hand dryer according to the present invention, wherein a jet outlet that blows an air flow toward the drying treatment space and water droplets blown off from a hand in the drying treatment space by the air flow blown from the jet outlet. The water receiving portion is provided, and the water receiving portion is not positioned on the extension of the central axis of the jet hole of the jet port while the air flow is blown from the jet port.

Embodiment 1 FIG.
The first embodiment is a hand dryer that can be attached to a wall. 1 to 3 show a hand dryer according to Embodiment 1 of the present invention, FIG. 1 is a perspective view showing an appearance of the hand dryer, FIG. 2 is a right side view, and FIG. 3 is a right side sectional view. First, the front-rear direction, the left-right direction, and the up-down direction described in the first embodiment are defined. In the front-rear direction, the front side (user side) of the hand dryer is “front”, and the opposite side of the front side is “rear”. Regarding the left and right direction, the right hand side is “right” and the left hand side is “left” when the hand dryer is viewed from the user standing in front of the hand dryer. In the vertical direction, the upper side is “upper” and the lower side is “lower”.

1 to 3, the casing 1 forms an outer shell on the upper side of the hand dryer. Below the casing 1, a drying processing space 3 having a drying processing space inlet 3 a is provided in front. The drying processing space 3 is a space where the front and left and right sides are opened and a hand can be freely inserted and removed. The water receiving portion 4 is connected to the lower surface 1a of the casing 1, and has a surface-shaped water receiving upper portion 4a extending downward from the lower surface 1a, and a surface-shaped water receiving portion connected to the lower end of the water receiving upper portion 4a and extending forward. The bottom 4b, the water receiving upper portion 4a, and the water receiving lower portion 4b are configured by a surface-shaped barrier structure 4c extending upward from the respective end edge portions. The water receiving upper portion 4a, the water receiving lower portion 4b and the barrier structure 4c are integrally formed. In use, the water droplets blown from the hand inserted into the drying treatment space are received by the water receiving upper portion 4a and the water receiving lower portion 4b of the water receiving portion 4, and the water received by the water receiving upper portion 4a and the water receiving lower portion 4b. The barrier structure 4c serves as a weir so as not to flow out from the ends of the water receiving upper portion 4a and the water receiving lower portion 4b. The positional relationship between the drying treatment space 3 and the water receiving portion 4 is such that a water receiving upper portion 4a is provided in the back (backward) of the drying processing space 3, and a water receiving lower portion 4b is provided at a part below the drying processing space 3. Is provided. Accordingly, the drying processing space 3 is partially surrounded by the lower surface 1a of the casing 1 and the water receiving portion 4, and the other space is open to the outside.

Further, the water receiving lower portion 4b is slightly inclined toward the front obliquely lower side, and a drain outlet 6 is provided at the lowermost portion thereof. A drain container 7 having an open container structure for storing water dripping from the drain port 6 is detachably attached to the water receiving part 4 b of the water receiving part 4 below the water receiving part 4 b.

A spout 10 is provided near the front end of the lower surface 1a of the casing 1 and protrudes downward from the lower surface 1a. In addition, intake ports 8 are provided on the left and right side surfaces of the casing 1. Further, in the casing 1, an air passage 5a and an air passage 5b communicating the intake port 8 and the jet port 10 are provided, and a high-pressure air flow is generated to generate a high-pressure air flow between the air passage 5a and the air passage 5b. A device 9 is incorporated.

The spout 10 is open downward along the vertical direction. The positional relationship between the jet port 10 and the water receiving part 4 will be described. All of the water receiving upper portion 4a, the water receiving lower portion 4b, and the barrier structure 4c are shifted rearward in the front-rear direction from the position on the extension of the blowing direction of the outlet 10 (the blowing direction of the high-speed air flow). . That is, the extension line extending the blowing direction of the jet outlet 10 does not intersect the water receiving portion 4, and the water receiving portion 4 is not positioned at a position on the extension of the jetting direction of the jet outlet 10, and is shifted from each other. It has become a relationship. Here, the blowing direction of the jet port 10 means a direction in which a high-speed air flow is blown out from the jet port 10 and is equivalent to the direction of the air flow immediately after being blown out from the jet port 10.

FIG. 4 is an enlarged side cross-sectional view of the spout 10 in FIG. The ejection hole 10a is a narrow passage through which an air flow blown from the ejection port 10 passes, and becomes narrower from the upstream side to the downstream side (exit) of the passing air flow. The inner wall 10b and the inner wall 10c are inner walls of the ejection holes 10a that face each other in the front-rear direction in a side cross-section obtained by cutting the ejection hole 10a of the ejection outlet 10 in a front-rear direction and a plane extending in the vertical direction. As shown in FIG. 4, a linear line obtained by connecting points between the inner wall 10 b and the inner wall 10 c and connecting the points where the distances to the inner wall 10 b and the inner wall 10 c are substantially equal to each other is defined as a central axis A. All of the water receiving upper portion 4a, the water receiving lower portion 4b, and the barrier structure 4c are located rearward in the front-rear direction from the position on the extension of the central axis A of the ejection hole 10a.

And the opening which is the opening end on the outlet side of the ejection hole 10a of the ejection port 10 does not face the water receiving part 4 directly, but is shifted in the front-rear direction. Therefore, in a state where the hand dryer is attached to the wall of the room such as a toilet, the opening of the spout 10 faces the floor surface of the room and the blowing direction of the spout 10 faces the floor surface. Yes. In other words, when projecting along the vertical direction, which is the blowing direction of the high-speed air flow, the position of the opening of the jet outlet 10 and the position of the water receiving section 4 do not overlap, and the water receiving capacity is higher than the opening of the jet outlet 10. The portion 4 is located rearwardly.

Next, the flow of air and water droplets when the hand dryer operates will be described. FIG. 5 is an explanatory diagram showing a state in which the user is using the hand dryer according to the first embodiment. As shown in FIG. 5, the hand dryer according to the first embodiment is installed on a wall 50 of a room such as a toilet. When the user stands in front of the front of the hand dryer and inserts a wet hand into the drying processing space 3 from the drying processing space entrance 3a, a hand detection sensor (see FIG. (Not shown) detects the hand. The high-pressure airflow generator 9 is operated by hand detection of a hand detection sensor (not shown), and external air is sucked into the air passage 5a from the intake port 8. The sucked air is converted into a high-pressure air flow by the high-pressure air flow generator 9. Then, the converted high-pressure air flow passes through the air passage 5b, is converted into a high-speed air flow at the jet outlet 10, and travels vertically from the jet outlet 10 toward the drying treatment space 3 as a high-speed air flow of 60 m / s or more. Is ejected downward. As for the speed of the high-speed air flow, the jet noise generated from the jet outlet 10 increases as the speed of the high-speed air flow increases, but when shortening the drying time has the highest priority over the increase of the jet noise, The speed of the high-speed air flow is preferably 100 m / s or more, more preferably 150 m / s or more.

Since the hand dryer is installed so that the drying processing space 3 is positioned lower than the shoulder of the user so that the hand can be easily inserted, the hand inserted into the drying processing space 3 from the front naturally comes from the wrist. It is inclined such that the position of the fingertip is lowered, and is in a posture toward a rear obliquely lower side (an oblique direction between the rear and the lower side). The high-speed airflow blown downward in the vertical direction from the jet nozzle 10 collides at an inclined angle with respect to the hand inserted obliquely downward and downward. For this reason, most of the colliding high-speed air flow changes into an air flow that advances in the fingertip direction along the hand, that is, an air flow that goes obliquely downward to the rear. And the water receiving part 4 exists in the direction of the back diagonally downward, and the air flow which goes to the back diagonally downward flows toward the water receiving part 4. Moreover, the water adhering to the hand is also blown off by the air flow that collides with the hand, and is blown off toward the water receiving portion 4 by the air flow directed diagonally downward rearward. The water droplets blown toward the water receiving portion 4 are received by the water receiving portion 4, flow down the surface of the water receiving portion 4 by its own weight, and are accommodated in the drain container 7 through the drain port 6.

The spout 10 has a slot-like opening that is elongated in the left-right direction, and the high-speed air flow blown out from the spout 10 is elongated in the left-right direction. Since the high-speed air flow blown out from the spout 10 is formed with a width sufficient for the width of the inserted hand in the left-right direction, the width of the inserted hand and the left and right of the inserted hand Care is taken that the high-speed airflow is sufficiently applied to the inserted hand without being affected by the position. The water adhering to the hand is peeled off and blown away from the hand by the high-speed air flow blown out from the spout 10. Then, when a high-speed air flow is blown from the jet port 10, the user slowly pulls out the hand inserted into the drying treatment space 3, so that the surface from the jet port 10 is removed from the surface of the inserted hand. The collision position of the high-speed air flow gradually moves from the wrist side to the fingertip side, and the water of the entire hand is blown away.

It should be noted that the length of the jet port 10 in the left-right direction is 80 mm or more if only one hand is dried, 150 mm or more, and more preferably 200 mm or more if both hands are dried simultaneously. Of course, when the jet nozzle 10 is divided into a plurality of parts in the left-right direction, the jet nozzles 10 divided into a plurality of parts are collectively considered as one, and are considered as the left and right lengths of the whole. Further, the slot width of the jet outlet 10 is preferably 2 mm or less in order to obtain a high-speed air flow.

On the other hand, in the high-speed air flow blown out from the jet nozzle 10, the high-speed air flow that did not collide with the inserted hand does not collide with the hand, so the wind direction is not changed and the wind speed is less attenuated, and the lower part in the vertical direction Proceed to And since there is no water receiving part 4 in the advancing direction, it passes near the water receiving part 4 without colliding with the water receiving part 4, and flows downward in the vertical direction as it is toward the floor surface.

According to the hand dryer configured as described above, the water receiving portion 4, that is, the water receiving upper portion 4a, the water receiving lower portion 4b, and the barrier structure 4c are all in the blowing direction of the jet port 10 (the blowing direction of the high-speed air flow). It is displaced rearward in the front-rear direction from the position on the extension. And the extension line which extended the blowing direction of the jet nozzle 10 and the water receiving part 4 do not cross | intersect, and the water receiving part 4 is not located in the position on the extension of the blowing direction of the jet nozzle 10, but is shifted back. is doing. And the water-receiving part 4 is located in the back and forth in the front-back direction rather than the position on the extension of the central axis A of the ejection hole 10a. And the opening part which is the opening end by the side of the exit of the ejection hole 10a of the ejection port 10 does not face the water receiving part 4, but is not opposite, and has shifted | deviated to the front-back direction.

Therefore, in the high-speed air flow blown out from the ejection port 10, the high-speed air flow that does not collide with the inserted hand and does not change the direction of the wind (for example, the high-speed air that is positioned on the outer side in the left-right direction from the position of the inserted hand). Since the water receiving part 4 is not positioned in the traveling direction of the air flow), the high-speed air flow that did not collide with the hand passes near the front of the water receiving part 4 with almost no collision with the water receiving part 4. To do. In this way, in the high-speed air flow blown from the jet port 10, the high-speed air flow that did not collide with the hand does not directly collide with the water receiving unit 4. The generated noise can be suppressed, and the noise when using the hand dryer can be reduced. In particular, the high-speed airflow that does not collide with the hand and does not change the wind direction does not attenuate wind speed due to the collision and maintains a high-speed state. However, noise can be effectively reduced by avoiding a direct collision with the water receiver 4.

On the other hand, in the high-speed air flow blown downward from the jet port 10 in the vertical direction, the high-speed air flow that collides with the inserted hand changes the wind direction due to the collision, and moves backward and diagonally along the hand toward the fingertip direction. The air flow is directed downward. Then, the water droplets peeled from the hand due to the collision with the high-speed air flow are carried by the wind that is inclined obliquely downward to the rear, blown off toward the water receiver 4, and received by the water receiver 4. Thus, even if the opening part of the jet nozzle 10 and the water receiving part 4 do not face each other, and even if the water receiving part 4 is not arranged at a position on the extension of the central axis A, the jet outlet 10 Even if the water receiving part 4 is not arranged at a position on the extension of the water blowing direction, the water receiving part 4 is arranged in the direction in which the water droplets are blown off. It can be effectively received and collected in the drain container 7, and the floor is not wetted and soiled.

Therefore, according to the hand dryer of the invention of the present application, water droplets flying from the hand are effectively received by the water receiver 4 and the high-speed air flow and the water receiver 4 that do not collide with the hand and do not contribute to the drying of the hand. By preventing the direct collision between the water receiver 4 and the high-speed airflow, the noise generated by the water receiver 4 colliding can be reduced without impairing the water droplet collection capability of the water receiver 4. In other words, the water receiving unit 4 can receive a drop of water flying from the hand and can have a rough selectivity that hardly receives the high-speed air flow blown from the jet outlet 10. It is possible to achieve both water droplet collection and noise reduction.

Further, in the hand dryer, when the hand is removed from the drying processing space 3, the high-speed air flow generator 9 is automatically stopped by a hand detection sensor (not shown), and the high-speed air flow from the outlet 10 is stopped. The In order to dry to the fingertips securely, it is necessary to stop the high-speed airflow after applying the high-speed airflow to the fingertip of the inserted hand, but the position of the fingertip is detected by a hand detection sensor (not shown). It is difficult to detect accurately. Therefore, generally, even after detecting that the hand has been removed from the drying processing space 3 by a hand detection sensor (not shown), the high-speed air flow continues to be blown for about 0.5 to 2 seconds, and thereafter By providing a delay operation to stop the high-speed airflow blowing, the high-speed airflow is stopped after the high-speed airflow is reliably applied to the fingertip.

In such a delay operation, after the hand is pulled out from the drying processing space 3, a state in which the high-speed air flow continues to blow out from the ejection port 10 in a state where the hand is not inserted into the drying processing space 3 occurs. Even after the drying process is completed, the noise accompanying the operation of the hand dryer continues for a while. For the user, the noise during the drying process associated with the user's own operation is easily tolerated, but the noise after drying is not directly related to the user's drying process, so noise generation is about 0.5 to 2 seconds. Even a short time is unacceptable and feels very uncomfortable.

However, in the present invention, even if a state in which the above-described delay operation is provided and a high-speed air flow is blown out from the ejection port 10 in a state where the hand is not inserted into the drying processing space 3, the high-speed air flow is directly generated. Since it does not collide with the water receiver 4, unpleasant noise that is not directly related to the drying process for the user can be reduced.

In the first embodiment, the blowing direction of the high-speed air flow at the jet port 10 is shown to be downward along the vertical direction. However, the blowing direction of the high-speed air flow at the jet port 10 is limited to this. However, the angle may be inclined to the front, back, left or right as long as it is below. For example, FIG. 6 and FIG. 7 are side views showing another example of the blowing direction of the high-speed air flow at the jet port 10 in the hand dryer of the first embodiment, and FIG. 8 is a partial view of the jet port 10 in FIG. FIG. 9 is an enlarged side cross-sectional view, and FIG. 9 is a side cross-sectional view in which the spout 10 in FIG. 7 is partially enlarged. 6 and 8, the blowing direction of the jet port 10 is directed obliquely forward and downward (oblique direction between the front and the lower direction) with respect to the vertical direction, and in FIGS. 7 and 9, the blowing direction of the jet port 10. However, it is directed diagonally downward (an oblique direction between the rear and the lower side) with respect to the vertical direction.

6, 7, 8, and 9 have the effects described above, and in addition, in FIGS. 6 and 8, the blowing direction of the ejection port 10 is obliquely forward and downward with respect to the vertical direction ( Since the size of the drying space 3 is larger than the size of the hand dryer in the front-rear direction, the size in the front-rear direction of the drying treatment space 3 can be made larger. Therefore, the size of the hand dryer in the front-rear direction can be reduced while sufficiently securing the size of the drying treatment space 3 in the front-rear direction with respect to the inserted hand. Moreover, in the hand dryer of FIG. 7 and FIG. 9, the bounce of the wind to a user can further be reduced.

In the first embodiment, in the front-rear direction, the distance L1 between the front end and the rear end of the lower surface 1a of the casing 1, the front end of the water receiver 4 and the rear end of the lower surface 1a of the casing 1 An example in which the water receiving portion 4 is disposed on the front side of the position of ½ of the distance L1 so as to satisfy the distance L2 between the distance L1 and L2> ½ × L1 is shown. The blowing direction of the jet outlet 10 is further angled obliquely rearward to satisfy L2 ≦ 1/2 × L1, and is ½ of the distance L1 between the front end and the rear end of the lower surface 1a of the casing 1. If the water receiving part 4 is arrange | positioned behind a position, the protrusion length to the front of the water receiving part 4 will become still shorter. Therefore, when the user inserts his / her hand into the drying processing space 3, the water receiving portion 4 becomes difficult to be seen by the casing 1 by visual observation from the user. Psychological feeling of pressure at the time of hand insertion into the can also be reduced.

The illustration of the air passage 5a, the air passage 5b, and the high-pressure airflow generator 9 provided inside the casing 1 is omitted. The casing 1, the air inlet 8, the air passage 5 a, the air passage 5 b, the high-pressure airflow generator 9, and the jet outlet 10 are collectively provided as a blower unit 100 as a unit having a single air blowing function. In the second embodiment, the casing 1 and the water receiver 4 are independent of each other. That is, the air blower 100 and the water receiver 4 are independent of each other. Therefore, the blower 100 and the water receiver 4 are independently attached to the wall 50 to which the hand dryer is attached. And the water receiving part 4 is arrange | positioned under the ventilation part 100. FIG. Under the water receiving part 4, a drain container 7 for storing the water received by the water receiving part 4 is attached to the water receiving part 4 so as to be removable. The only difference from the first embodiment is that the air blowing unit 100 and the water receiving unit 4 are independent from each other, and the other configuration is the same as that of the first embodiment.

According to the hand dryer having the above configuration, the same effect as that of the first embodiment can be obtained, and the position of the water receiving portion 4 can be adjusted and installed according to the environment and the user to which the hand dryer is attached.
