The waterproof wall 44 prevents the water droplets blown off from the hand and the water droplets blown off from the hand and attached to the back side water receiving portion 4a or the bottom side water receiving portion 4 from splashing out of the hand insertion portion 3 . The waterproof wall 44 is provided on the entire outer periphery of the water receiving portion 4.

The waterproof wall 44 has a waterproof wall rising portion 44a provided on the water receiving portion 4 side on the back side or bottom side of the hand insertion portion 3 in a state of rising upward or forward from the edge of the water receiving portion 4; And a waterproof wall inclined portion 44b connected to the wall rising portion 44a and provided on the outer side of the waterproof wall rising portion 44a and having an outward upward slope. The waterproof wall inclined portion 44 b is inclined in the direction toward the outside as it is separated from the water receiving portion 4. The waterproof wall 44 is provided over the entire length of the left and right and front end edges of the water receiving portion 4.

The waterproof wall rising portion 44a and the waterproof wall inclined portion 44b of the waterproofing wall 44 on the bottom side extending upward from the bottom side water receiving portion 4b have an outward upward slope. The outward upward slope in this case is an outward and upward slope with respect to the bottom side water receptacle 4b. The waterproof wall rising portion 44a and the waterproof wall inclined portion 44b of the rear side waterproof wall 44 extending forward from the rear side water receiving portion 4a have an outward upward slope. The outward upward slope in this case is an outward and forward slope with respect to the back side water receptacle 4a. The waterproof wall rising portion 44 a of the waterproof wall 44 on the bottom side may be provided along the vertical direction. The waterproof wall rising portion 44 a of the rear-side waterproof wall 44 may be provided along the front-rear direction.

By providing the waterproof wall sloped portion 44b on the waterproof wall 44, the water blown from the hand and attached to the waterproof wall sloped portion 44b does not stay on the waterproof wall 44 and does not flow to the outside of the casing 1 either. It flows along the inclined portion 44 b and falls to the back side or the bottom side of the hand insertion portion 3. The water droplets attached to the waterproof wall sloped portion 44b of the waterproof wall 44 on the bottom side extending upward from the bottom side water receiving portion 4b flows downward along the waterproof wall sloped portion 44b of the waterproof wall 44 on the bottom side by its own weight. It flows along the waterproof wall rising portion 44 a of the waterproof wall 44 on the side and flows to the removable bottom portion 42 b which is the bottom side water receiving portion 4 b below the hand insertion portion 3. The water droplets that have flowed to the mounting / dismounting bottom portion 42 b are collected in the drain container 6 via the drainage port 5.

Moreover, the water droplet adhering to the waterproof wall inclined part 44b of the waterproof wall 44 of the back side extended forward from the back side water receiving part 4a moves below by dead weight. The lower portion of the waterproof wall sloped portion 44b of the waterproof wall 44 on the back side is connected to the waterproof wall sloped portion 44b of the waterproof wall 44 on the bottom side extending upward from the bottom surface water receiving portion 4b. Thus, the water droplets attached to the waterproof wall sloped portion 44b of the waterproof wall 44 on the back side flow downward along the waterproof wall sloped portion 44b of the waterproof wall 44 on the bottom side, and the waterproof wall slopes of the waterproof wall 44 on the bottom side The portion 44b and the waterproof wall rising portion 44a of the waterproof wall 44 on the bottom side flow to the removable bottom portion 42b which is the bottom side water receiving portion 4b below the hand insertion portion 3. The water droplets that have flowed to the mounting / dismounting bottom portion 42 b are collected in the drain container 6 via the drainage port 5.

If the waterproof wall sloped portion 44b is not provided on the waterproof wall 44, the water droplets blown off from the hand remain on the waterproof wall 44, and the user next uses the hand in the hand insertion portion 3 and the nozzle 12 When the air flow is blown out, the air flow may hit the hand and scatter outside of the casing 1. The water droplets blown away from the hand contain not only water but also soap or detergent ingredients, sebum and dirt of the user's hand, so that a smell is generated when dry. In addition, hand dryers are often installed at places used by many people, such as commercial facilities and restaurants. For this reason, it is preferable that the water droplets blown off from the hand flow through the water receiving portion 4 promptly after the use of the hand dryer 100 and can be collected in the drain container 6.

By providing the waterproof wall 44 having the above-described structure, the hand dryer 100 can quickly drain the water droplets blown off from the hand and attached to the waterproof wall 44 to the water receiving portion 4 and collect them in the drain container 6 It is. That is, the hand drying apparatus 100 can quickly squirt the water droplets blown off from the hand and attached to the waterproof wall inclined portion 44b on the bottom side, and the water droplets attached to the waterproof wall inclined portion 44b on the bottom side and the waterproof wall inclined portion 44b on the back side. It is possible to flow to the water receiver 4 and collect it in the drain container 6.

Thus, the hand dryer 100 prevents the water droplets remaining on the upper surface of the waterproof wall 44 from being used by the previous user from being scattered outside the hand dryer 100 by the air flow striking the next user's hand. It is possible to prevent water droplets remaining on the waterproof wall 44 from wetting the floor or the wash basin below the hand dryer 100 after use. And the hand dryer 100 can suppress generation | occurrence | production of the odor resulting from the water droplet which was blown off from the hand and scattered to the exterior of the hand dryer 100 dried. Further, since the hand dryer 100 can suppress the water droplets from remaining on the upper surface of the waterproof wall 44, it is possible to suppress the generation of the odor due to the water droplets remaining on the upper surface of the waterproof wall 44 drying. Moreover, the hand dryer 100 can suppress that the user who uses next touches the water droplet which has been on the waterproof wall 44. Therefore, the hand dryer 100 can improve the hygiene of the hand dryer 100 and the hygiene around the hand dryer 100.

Below the water receiving portion 4, a drain container 6 for storing water dropped from the drainage port 5 is detachably provided to the casing 1. The drain container 6 is fixed to the casing 1 by the casing locking projection 19 a which is a part of the casing 1 being locked to the drain container locking receiving portion 19 b. The attachment and detachment of the drain container 6 to the casing 1 will be described later.

The inner surface of the manual insertion portion 3 is coated with a silicon-based water-repellent coating or a fluorine-based water-repellent coating, a coating of a material having hydrophilicity represented by titanium oxide, or is impregnated with an antibacterial agent . Thereby, the inner surface of the hand insertion part 3 is reduced in the adhesion of dirt, and the growth of bacteria is reduced.

Above the hand insertion portion 3, a nozzle 12 for blowing high-speed air downward toward the hand insertion portion 3 is provided. Near the back side of the nozzle 12, a hand detection sensor 14 for detecting the presence or absence of a hand in the hand insertion unit 3 is provided. On the side surface of the casing 1 located above the hand insertion portion 3, a maintenance panel 20 in which an air inlet 9 is formed is disposed. On a part of the surface of the maintenance panel 20, an inclined surface is provided which inclines toward the center in the left-right direction as it goes from the rear side to the front side. The air inlet 9 is configured by a gap provided between the front edge of the inclined surface and the back surface of the maintenance panel 20.

Above the hand insertion portion 3, a box-like space is formed by the base 7 and the casing 1 which form the outer shell of the back side hand dryer 100. The base 7 is fixed to the back side of the casing 1 by a fixed holding plate 16. In the box-like space, a high-pressure air flow generation device 8 which is an air flow generation unit constituted by a DC (Direct Current) brushless motor and a turbofan rotated by the DC brushless motor, and a hand detection sensor 14 A control circuit (not shown) for controlling the operation of the high pressure air flow generator 8 in accordance with a hand detection signal is incorporated. A commutator motor or an induction motor may be used instead of the DC brushless motor.

Further, in the box-like space, the intake air passage 10 communicating the intake side of the high pressure airflow generating device 8 with the intake port 9 and the exhaust side of the high pressure airflow generating device 8 communicate with the nozzle 12 An exhaust air passage 13 is provided. In the middle of the exhaust air passage 13 and upstream of the nozzle 12, a heater 15 is provided which heats and warms the air sent from the high-pressure air flow generating device 8.

Below, the structure of the nozzle 12 and the exhaust air path 13 is demonstrated. The exhaust air passage 13 is configured by connecting the nozzle 12 to a motor cover 31 covering the high pressure air flow generating device 8 via a seal component 32 for sealing the high pressure air flow generated from the high pressure air flow generating device 8. Ru. The seal component 32 is preferably made of silicon resin having high heat resistance in consideration of heat generation of the heater 15 disposed in the exhaust air passage 13. The motor cover 31 and the exhaust air passage 13 are fixed by screws. For this reason, in the hand dryer 100, replacement of parts of the heater 15 and the high pressure air flow generator 8 is facilitated, and cleaning of the inside of the exhaust air passage 13 after being used for a long time is also enabled.

The exhaust air passage 13 is inclined downward as it goes forward, and in the middle of the exhaust air passage 13, the downstream side is bent in the backward direction. That is, the exhaust air passage 13 is inclined downward as it goes from the upstream side to the downstream side, and is bent in the direction toward the rear at an intermediate portion on the downstream side of the exhaust air passage 13. The above-described nozzle 12 is provided on the downstream side of the exhaust air passage 13. The blowoff air blown out from the nozzle 12 to the hand insertion portion 3 is directed rearward in accordance with the downstream extension direction of the exhaust air passage 13.

As a result, among the components inside the casing 1 except the casing 1, the exhaust air passage 13 protrudes most forward in the front-rear direction. The nozzle 12 is provided downstream after the exhaust air passage 13 is bent rearward. Then, in the front-rear direction of the casing 1, the position of the seal component front surface 32 a, which is a surface located forward in the seal component 32, and the position of the nozzle 12 become substantially the same position.

The dimension in the front-rear direction of the casing 1 is determined by the position of the exhaust air passage 13 located most forward in the casing 1. The distance between the front face of the casing 1 and the outlet of the nozzle 12 is determined by the dimension in the front-rear direction of the casing 1 determined by the position of the exhaust air passage 13 positioned most forwardly inside the casing 1 and the position of the nozzle 12 The nozzle 12 can be minimized, the nozzle 12 is disposed near the front of the casing 1, and the wind blown from the nozzle 12 is directed rearward. As a result, the water droplets blown from the hand toward the front side in the hand insertion portion 3 are reduced, which is convenient for the user. And, by setting the distance between the front surface of the casing 1 and the outlet of the nozzle 12 to be 10 mm or less, the water droplets blown off from the hand toward the front side in the hand insertion portion 3 become smaller, which is more convenient for the user. Get better. When an adult user is assumed, the distance between the outlet of the nozzle 12 and the back side water receiving portion 4a is about 110 mm to 130 mm, so that the user can use his hand in the hand insertion portion 3 When it happens, the whole hand is hit by the wind, and the user's hand does not touch the hand insertion portion 3.

In the hand drying apparatus 100, the exhaust air passage 13 is disposed in front of the seal component front surface 32a, and the blowout air blown out from the nozzle 12 to the hand insertion portion 3 is rearward and downward from the same position as the seal component front surface 32a Because it is blown out to the side, it is possible to minimize the protrusion of the main body from the wall while securing a sufficient space for inserting a hand. Moreover, since the water droplets blown off from the hand are blown toward the back side water receiving part 4a on the back side after hitting the hand, it is possible to be surely recovered by the water receiving part 4 below the hand insertion part 3. it can. Further, assuming an adult user, the depth dimension D of the casing 1 being 150 mm makes it possible to obtain a hygienic hand dryer 100 that is easy for the user to use and can reliably collect water droplets. . Further, by setting the depth dimension D of the casing 1 to 150 mm, the hand dryer 100 can be installed in a narrow washroom and a narrow toilet space with a small amount of protrusion from the wall when the hand dryer 100 is mounted on the wall. You can get

When the nozzle 12 is disposed rearward of the seal component front surface 32a in the front-rear direction, the front surface of the casing 1 in the front-rear direction is smaller than when the nozzle 12 is disposed at the same position as the seal component front surface 32a. The distance between the nozzle 12 and the outlet is long. And in this case, even if a hand is inserted in the hand insertion part 3, the blowout air blown out from the nozzle 12 may not fully touch the whole hand, and the hand may not be sufficiently dried. In this case, the area on the front side of the casing 1 in the hand insertion portion 3 which is not exposed to the blowing air is wide, and the hand inserted in the hand insertion portion 3 can not be sufficiently dried.

A filter (not shown) made of resin or metal for removing dust in the air sucked into the high pressure air flow generating device 8 is integrally formed with the maintenance panel 20 at the front stage of the intake air passage 10. It is attached in the state which can be detached to the direction. The filter can be attached and detached by the operation of inserting and removing the maintenance panel 20 to the side surface of the casing 1. The area of the filter is made larger than the cross-sectional area in the direction perpendicular to the ventilation direction in the intake port 9 and the intake air passage 10. The filter may be a High Efficiency Particulate Air (HEPA) filter or an antibacterial filter.

The intake port 9 may be provided on the back of the casing 1. When the intake port 9 is provided on the back surface of the casing 1, the intake port 9 is disposed in a part of the base 7.

A push button is provided. The push button has a spring-like shape so as to be movable in the vertical direction when the push button is pressed by hand. A tact switch or a capacitance type switch is used as the operation switch.

The operation switch portion is fixed to the upper side of the intake air passage 10 in the casing 1. The casing 1 is provided with an upper surface opening 37 such that the operation switch portion appears on the upper surface of the casing 1 when the casing 1 is attached to the base 7. In a state where the casing 1 is attached to the base 7, the operation switch portion is fitted in the upper surface opening portion 37. The casing 1 and the operation switch portion are fixed at a peripheral position of the upper surface opening portion 37, and can be attached without a gap between the upper surface opening portion 37 and the operation switch portion. In addition, you may use a screw for fixation with the casing 1 and an operation switch part.

Further, the operation switch portion is covered with an operation portion panel 18 attached to the casing 1 so as to be openable and closable. The procedure for operating the operation switch unit will be described. First, the operation panel 18 is moved horizontally toward the outside in the left-right direction of the casing 1. Next, the operation panel 18 is rotated upward around the rotation axis of the operation panel 18 to open the operation panel 18. The rotation axis of the operation panel 18 is movable in the left-right direction of the casing 1. When the operation panel 18 is in the “closed” state, no gap is generated between the casing 1 and the operation panel 18. Thereby, it looks good and can prevent the entry of dust and the entry of water into the interior of the casing 1. In addition, when opening the operation panel 18, it is necessary to move the operation panel 18 horizontally outward in the left-right direction of the casing 1, so a person other than the maintenance worker who is grasping the operation method performs the operation. It is possible to prevent the switch section from being tampered with.

A label or a plastic film is attached to the upper surface of the operation switch cover, and power on / off switching of the wind speed of blowing air, and state display explanation of turning on / off of the heater 15 are displayed. Further, the operation switch cover is provided with an opening through which an LED (Light Emitting Diode) for indicating the operating state of the hand dryer 100 is exposed. The opening provided in the operation switch cover for transmitting the LED is covered with a label or a plastic film, so that it is possible to prevent the entry of water into the interior of the casing 1 and the entry of dust.

In addition, the drain container 6 does not shake even if a load is applied downward to the drain container 6 in a state where the drain container 6 is attached to the casing 1, so the side surface 1 a of the casing on the side of the hand dryer 100 and the drain container It is possible to prevent the occurrence of a gap at the seam 53 with the side surface 6b of the. Further, when the upper surface of the drain container rear protrusion 77 contacts the lower surface on the back side of the fixed bottom surface portion 41b, the mounting strength at the time of mounting the drain container 6 to the casing 1 is increased. Thereby, even when the drain container 6 is full of water, the drain container 6 does not tilt. Therefore, the hand dryer 100 can improve the reliability of the connection with the casing 1 of the drain container 6 which can be attached or detached to the casing 1.

Further, the top surface of the drain container rear protrusion 77 is circular or square. The drain container rear projection 77 is formed with a narrow width within the range of the width of the left and right outer frames on the rear side of the drain container 6. That is, the area of the drain container rear protrusion 77 is made extremely smaller than the area of the lower surface of the fixed bottom surface portion 41 b.

The drain container 6 and the removable bottom portion 42b are connected by fitting the drain container fitting portion 71 and the removable bottom portion fitting portion 72 and fitting the drain container fitting portion 75 and the removable bottom portion fitting portion 76. Be done. Then, in a state where the drain container 6 is attached to the casing 1, the drain container rear protrusion 77 comes in contact with the lower surface of the fixed bottom surface portion 41 b.

Only the drain container rear protrusion 77 is in contact with the lower surface of the fixed bottom surface portion 41b, and the area of the drain container rear protrusion 77 is very small compared to the area of the lower surface of the fixed bottom surface portion 41b, Even when the drain container 6 is inserted and removed, the friction with the lower surface of the fixed bottom surface portion 41b is reduced. Thus, the contact between the drain container rear projection 77 and the lower surface of the fixed bottom surface portion 41 b does not adversely affect the insertability of the drain container 6. Therefore, the hand dryer 100 can insert and remove the drain container 6 into and from the casing 1 without the detachable bottom surface portion 42b being caught on the lower surface of the fixed bottom surface portion 41b.

The drain container rear projection 77 may be configured to project upward from the upper surfaces of the left and right outer frames on the rear side of the drain container 6. Also in this case, only the drain container rear protrusion 77 is in contact with the lower surface of the fixed bottom surface portion 41b. Also in this case, in the state where the drain container rear protrusion 77 attaches the drain container 6 to the casing 1, the drain container 6 and the casing configured by the casing engagement protrusion 19 a and the drain container engagement receiving portion 19 b It is provided in the position which is back rather than the fitting structure with 1, and becomes the lower part of the fixed bottom face part 41b. The upper surface of the drain container rear protrusion 77 contacts the back side of the fixed bottom surface portion 41b, that is, the lower surface of the fixed bottom surface portion 41b when the drain container 6 is attached to the casing 1. That is, the upper surface of the drain container rear protrusion 77 contacts the lower surface of the fixed bottom surface portion 41b at the rear of the drain container engagement receiving portion 19b.

Moreover, in the state in which the drain container 6 was attached to the casing 1, the attachment / detachment bottom surface part 42b is separated from the fixed bottom surface part 41b. Therefore, in the hand drying apparatus 100, even when the drain container 6 is inserted into and removed from the casing 1, the removable bottom surface portion 42b and the fixed bottom surface portion 41b do not rub, and the removable bottom surface portion 42b and the fixed bottom surface portion 41b are drain container 6 Does not adversely affect the insertability of the

Further, by providing a plurality of drain container rear protrusions 77, the drain container 6 is firmly fixed to the lower surface of the fixed bottom surface portion 41b, and the mounting strength at the time of mounting the drain container 6 to the casing 1 is increased.

In addition, even if the drain container rear projection 77 contacts the lower surface of the fixed bottom surface portion 41b or a gap is generated between the drain container rear protrusion 77 and the lower surface of the fixed bottom surface portion 41b due to dimensional tolerance in manufacturing. Since the structure has almost no gap, smooth insertion and removal can be performed without rattling.

In addition, even if a child hangs on the drain container 6 or pushes the drain container 6 forcibly by mistake, the front portion of the drain container 6 is inclined downward by providing the drain container rear projection 77. Can be prevented.

In addition, the drain container rear protrusion 77 has a circular or square upper surface and a low height. As a result, the drain container rear projection 77 does not break or break even when a load is applied downward to the drain container 6 due to mischief or the like, and even when the drain container 6 is repeatedly inserted and removed. It will not be damaged.

Therefore, it is possible for the hand dryer 100 to wipe and clean the attachment / detachment bottom portion 42b which easily gets dirty as the use continues, without the drain container 6 being removed from the casing 1 .

Further, after the drain container 6 is removed from the casing 1, the hand dryer 100 can remove the detachable bottom surface portion 42 b from the drain container 6 and clean it easily. Therefore, when the water accumulated in the drain container 6 is discarded, the removable bottom surface portion 42 b can be removed from the drain container 6 and cleaned easily.

Further, the drain container 6 mounted to the casing 1 is held from below by the tank receiving portion 81 provided below the fixed bottom surface portion 41 b. The tank receiver 81 is provided to extend forward from the back side of the casing 1. When cleaning the wash basin directly under the hand dryer 100 installed on the wash basin or above the wash basin, the drain container 6 is removed, and the hand is inserted into the hand insertion portion 3 for cleaning. Here, if the tank receiving portion 81 is largely projected forward, it becomes difficult to clean the region directly below the hand dryer 100.

In the hand dryer 100, since the drain container 6 is fixed to the lower surface of the fixed bottom surface portion 41b by the drain container rear projection portion 77, it is intended to have a structure capable of withstanding downward load during cleaning of the removable bottom surface portion 42b. It is not necessary to extend the tank receiving portion 81 for holding the drain container 6 from below as long as the front side. Therefore, even when the hand dryer 100 is installed above the wash basin or above the wash basin, cleaning of the wash basin directly below the hand dryer 100 is easy.

Next, collection of water droplets in the hand dryer 100 will be described. When the user inserts a hand into the hand insertion portion 3, the high pressure air flow generator 8 operates to blow high speed air from the nozzle 12. As a result, the high speed air blows off the water droplets from the hand. The water droplets blown off from the hand are received by the water receiver 4. As described above, in the bottom surface side water receiving portion 4b of the water receiving portion 4, in the overlapping region 43, the outer edge region 42ba on the rear side in the detachable bottom surface portion 42b and the outer edge region 41ba on the front side in the fixed bottom surface portion 41b. A drainage port 5 which is a gap between the two is provided.

The water droplets received by the water receiving unit 4 are sent to the drainage port 5 and collected in the drain container 6 disposed below the water receiving unit 4. The water droplets received by the mounting / dismounting bottom surface portion 42 b flow on the mounting / dismounting bottom surface portion 42 b to reach the drainage port 5, and drip from the drainage port 5 into the drain container 6. On the other hand, the water droplets received by the fixed bottom surface portion 41 b flow forward, reach the drainage port 5, and drip from the drainage port 5 into the drain container 6. Further, the water droplets received by the back side water receiving portion 4 a flow to the fixed bottom surface portion 41 b, flow forward to the fixed bottom surface portion 41 b, reach the drainage port 5, and drip from the drainage port 5 to the drain container 6. As described above, the water droplets received by the water receiving portion 4 are transferred to the drain container 6 through the drainage port 5, which is a gap provided in the divided portion between the fixed bottom surface portion 41b and the detachable bottom surface portion 42b in the bottom surface side water receiving portion 4b. Led.

As a result, it is possible to suppress the deposition of dirt on the divided portions of the fixed bottom surface portion 41b and the detachable bottom surface portion 42b in the bottom surface side water receiving portion 4b. That is, by providing a gap in the division between the fixed bottom surface portion 41b and the mounting / dismounting bottom surface portion 42b to form the drainage port 5, dirt on the division portion flows out with water droplets, so that deposition of dirt on the division portion can be suppressed. . In addition, since the fixed bottom surface portion 41b and the removable bottom surface portion 42b are not directly fixed, and the fixed bottom surface portion 41b and the removable bottom surface portion 42b are not fixed by the fitting structure, the bottom surface side water receiving portion 4b Shape is simplified and cleanability is improved.

Further, in the process in which the water droplets received by the water receiving unit 4 flow to the drain container 6, the dirt is easily accumulated in the bottom side water receiving unit 4b. The bottom side water receiving part 4b is exposed mainly to the user's eyes, and when the frequency of cleaning is low, the appearance is impaired.

Here, the mounting and demounting surface portion 42 b is not configured to be mounted to and detached from the casing 1, and as described above, may be configured to be mounted and detached separately from the drain container 6. As a result, the mounting and demounting surface portion 42b can be easily removed alone without using a tool. Therefore, the hand drying apparatus 100 can easily remove the removable bottom portion 42b which is prone to accumulation of dirt and must be cleaned frequently, and therefore the sanitation and cleanliness of the water receiving portion 4 can be maintained. Also, the cleanability and maintainability of the water receiving portion 4 is improved. In addition, the same effect can be acquired even if it is a nail | claw structure other than fitting structure about the fixing method of the attachment / detachment bottom face part 42b with respect to the drain container 6. FIG.

Further, by removing the drain container 6 from the casing 1, the fixed bottom surface portion 41 b can be easily cleaned. Therefore, when the hand is dried, the water droplets spattered adhere to the fixed bottom surface portion 41b, and while the use is continued, dirt gradually adheres, but the fixed bottom surface portion 41b can be easily cleaned.

Further, the mounting / dismounting bottom surface portion 42 b is supported by the drain container 6 and is not fixed to the fixed bottom surface portion 41 b. And the drain container 6 is directly supported by the casing 1 as mentioned above. Thereby, even if the weight of the water accumulated in the drain container 6 becomes heavy when the drain container 6 is full of water, no direct force is applied to the mounting / dismounting bottom surface portion 42b and the fixed bottom surface portion 41b. Can be simplified, and the cleanability of the water receiver 4 can be improved.

In addition, the detachable bottom surface 42b and the fixed bottom surface 41b can be configured in a simple shape with less unevenness by having a structure in which the detachable bottom surface 42b is not engaged with the fixed bottom surface 41b, so the bottom side water receiver Cleaning of 4b becomes easy.

In addition, the hand dryer 100 is configured to be locked to the drain container 6 without locking the mounting / dismounting bottom portion 42 b where dirt is likely to be accumulated to the casing 1. Then, a fitting structure 11 for fitting and locking the detachable bottom surface portion 42b to the drain container 6 is provided at the lower part of the outer peripheral edge portion of the detachable bottom surface portion 42b. That is, in the hand dryer 100, the fitting structure 11 faces the exterior surface of the hand dryer 100. With this configuration, in the hand dryer 100, the drop of water drops from the fitting structure 11 which is the seam of the parts in which the dirt gradually comes along by continuing the use, that is, the seam between the detachable bottom surface 42b and the drain container 6. It can be arranged outside the area facing the direct blowing hand insertion part 3. Therefore, since the water received by bottom side water receiving part 4b does not reach fitting structure part 11, hand dryer 100 can control that dirt accumulates on fitting structure part 11, and cleaning frequency is low. , It becomes possible to maintain the beauty around the bottom side water receiving part 4b.

In addition, the fitting structure 11 for locking the detachable bottom surface 42b to which dirt gradually adheres by continuing to be used by the detachable bottom surface 42b disposed above the drain container 6 is viewed from above the user. It can cover up the eyes. This makes it possible to reduce the unpleasant feeling that the user does not want to insert a hand into the hand insertion portion 3 due to the appearance of the periphery of the bottom side water receiving portion 4b.

Moreover, the water receiving part 4 is comprised by two components of the back surface side water receiving part 4a and the bottom surface side water receiving part 4b, and the division part is made into one place. In general, the divisions of parts are prone to dirt accumulation. However, since the water receiving portion 4 has only one divided portion, it is possible to minimize the deposition position of the dirt.

Moreover, the waterproof wall 44 by the standup of the curved surface structure which protruded in the front or upper direction is provided in the left-right direction of the water receiving part 4, and the front edge part. And the fitting structure of the drain container 6 and the casing 1 is provided in the lower part of the waterproof wall 44. For this reason, the water droplets received by the waterproof wall 44 promptly flow to the detachable bottom surface portion 42 b or the fixed bottom surface portion 41 b and are led to the drain container 6 through the drainage port 5. As a result, it is difficult for the water droplets received by the waterproof wall 44 to reach the fitting structure of the drain container 6 and the casing 1, and it is possible to suppress the accumulation of dirt on the fitting structure.

As described above, the hand dryer 100 according to the first embodiment has the upper surface of the drain container rear protrusion 77 in contact with the lower surface of the fixed bottom surface portion 41b while the drain container 6 is attached to the casing 1. The drain container 6 is fixed to the lower surface of the fixed bottom surface portion 41b. As a result, the drain container 6 attached to the casing 1 is in a state of no rattling, is not rattling even if a load is applied to the lower side, and it is possible to wipe and clean it unreasonably.

Therefore, the hand dryer 100 can improve the reliability of the connection with the casing 1 of the drain container 6 which can be attached or detached to the casing 1.

The configuration shown in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and one of the configurations is possible within the scope of the present invention. Parts can be omitted or changed.
