  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIGS. 1 and 2, the main body 1 fixed to the wall surface has a jet nozzle 2 that jets a high-speed jet toward the upper surface of the main body 1 toward the wall surface opposite to the user side, and a high-speed jet from the jet nozzle 2. A water receiver 3 is attached as water droplet collecting means installed in the direction of jetting and substantially parallel to the floor surface. A treatment space 4 for inserting a hand between the jet nozzle 2 and the water receiver 3 and drying is formed facing the main body 1 and in the vicinity of the upper surface portion 5 of the main body and in a free space. The processing space 4 is a space for drying the hand constituted by the ejection nozzle 2 and the water receiver 3. If the surface opposite to the main body wall surface portion 6 when the main body is installed on the wall surface is the main body front surface portion 7, the processing space 4 is the front surface 8 on the main body front surface portion 7 side, the back surface 9 on the opposite side, and the upper surface 10 on the ceiling side. The floor side is configured as a lower surface 11. Each surface is not only a flat surface but also a curved surface.

  The opening 12 is constituted by a plurality of flat surfaces or curved surfaces of the processing space. For example, in this embodiment, the front surface 8 and the upper surface 10 and the side surface 13 of the processing space 4 are open.

  The main body 1 is provided with a high-speed blower 14 as a blowing means, a PTC heater 15 as a heating means, and a control circuit 16 as a control means. A sensor 17, which is detection means for detecting a hand inserted into the processing space 4 and energizing the high-speed blower 14 and the PTC heater 15, is attached to a part of the main body 1.

  When a wet hand is inserted into the processing space 4 in the above configuration, the presence of the hand is detected by the sensor 17 and the high-speed blower 14 and the PTC heater 15 are operated. As a result, external air is sucked from a suction port 19 installed in the vicinity of the lower surface 18 of the main body, and warm air is formed through the high-speed blower 14 and the PTC heater 15 and is blown from the ejection nozzle 2. At this time, warm air hits the hand that has been put out, and the hand is dried. When the hand is retracted, the detection of the sensor 17 is lost, so the high speed blower 14 and the PTC heater 15 are stopped. Such operation is performed by the control circuit 16.

  The opening 12 that allows a user to easily insert his / her hand from the user's side is an opening space in which the user can freely enter and exit regardless of the direction of the user's hand. When the hand is put into the processing space 4 while facing the inside of the body, if the opening 12 is narrow, the hand may not be in contact with or put into a part of the main body 1, such a state. Can be avoided.

  Furthermore, since the space where the hand can be freely put in gives the user a sense of cleanliness, the cleanliness is improved both psychologically and physically.

  Water droplets that have separated and collided with the water receiver 3 from the hand move to the drain tank 21 through the drain hole 20 from the water receiver 3. The drain tank 21 stores a certain amount of water droplets. The drain tank 21 is regularly maintained and discarded water drops are discarded.

  The high-speed blower 14 is an electric blower generally used for a vacuum cleaner or the like, and includes a motor with a brush and a motor with a brushless motor, and uses a turbo fan to cool a temperature rise due to high-speed rotation of the motor. While sending.

(Embodiment 2)
The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 3, the opening distance 22 of the opening 12 indicates the distance of the processing space 4 between the wall-side surface of the main body 1 and the user-side surface, and this space is generally a palm. Since the longest distance is about 100 mm, it is necessary to open the opening distance 22 by 100 mm or more.

(Embodiment 3)
The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 4 to FIG. 6, a jet nozzle 2 that jets a high-speed jet on the wall side and the ceiling side above the main body 1 and a water receiver 3 installed so as to face the jet nozzle 2 are attached. ing. The water receiver 3 is located on the lower surface 11 and the rear surface 9 of the processing space 4 and is installed to collect water droplets. When the jet nozzle 2 faces the user side, the wind hits the user, which makes it uncomfortable. Therefore, the processing space 4 for inserting a hand above the jet nozzle 2 and the water receiver 3 to dry it is used. Is formed in the free space above the main body 1.

  Therefore, when viewed from above the main body 1, the ejection nozzle 2 can be visually observed.

  With such a configuration, the jet direction of the jet flow of the jet nozzle 2 is a direction in which water droplets are jetted onto the back surface 9 of the processing space 4.

  At this time, in order to prevent water droplets from entering the ejection nozzle 2 naturally, the ejection nozzle 2 is not installed at a position closest to the floor surface of the processing space 4 through which the water droplets always pass. A drain hole 20 is provided at a position closest to the floor surface.

  Here, when water droplets enter the ejection nozzle 2, it causes a failure. Therefore, a U-shaped trap 23 is installed between the ejection nozzle 2 and the high-speed blower 14 and the water droplets enter the high-speed blower 14. To prevent.

  Further, when many water droplets enter the trap 23, the safety can be further improved by installing a door 24 that opens due to the weight of the water droplet at a part of the lowest point of the trap 23. In order to secure the ventilation path again when there is no water drop, a spring 25 is provided so as to close the door 24 and is closed when the weight of the water drop is small.

  The hand drying apparatus according to the present invention has an opening that allows a user to easily put a hand from the user side of the processing space, and is provided with water droplet recovery means for recovering water droplets removed from the hand, thereby widening the processing space. Since there are no obstacles when inserting the hand, it can be easily put in hand. Further, since the water droplets have water droplet collecting means, there is an effect that the water droplets can be prevented from getting dirty outside the main body such as walls and floors.

  Therefore, it is effective for an apparatus for washing hands in a washroom, a toilet, etc., and drying wet hands, and can also be applied as a use for drying things that are generally wet with liquid.
