Description

  The present invention relates to a hand drying apparatus for washing hands in a washroom or a toilet and drying wet hands.

  Conventionally, this type of hand-drying apparatus has been known to be dried by high-speed air (for example, see Patent Document 1).

  Hereinafter, the hand dryer will be described with reference to FIGS. 40 and 41. FIG.

  As shown in FIGS. 40 and 41, the main body 101 fixed to the wall surface is a nozzle portion 102 that ejects a high-speed jet at the lower portion, and a water receiver that is a water droplet collecting means installed in the direction of ejecting the high-speed jet from the nozzle portion 102. 103 is attached. A treatment space 104 is formed between the nozzle portion 102 and the water receiver 103 for inserting and drying the hand. In the main body 101, an air blowing means 105, a heat generating means 106, and a control means 107 are provided. A detection means 108 for detecting a hand inserted into the processing space 104 and energizing the air blowing means 105 and the heat generation means 106 is attached to a part of the main body 101.

As a result, external air is sucked from the suction port 109 installed in the lower part of the main body, and warm air is formed through the blowing means 105 and the heating means 106 and is blown from the nozzle portion 102. 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 means 108 is not detected, so the air blowing means 105 and the heat generating means 106 are stopped. Such operation is performed by the control means 107.

  Although the water droplets away from the hand are collected in the water receiver 103, they are easily scattered by the air blown from the nozzle portion 102, and therefore the front and side protruding walls 110 of the water receiver 103 are attached to prevent scattering to the surroundings. It is configured. Further, the water droplets collected in the water receiver pass through the drain hole 111 in the water receiver, and a certain amount is stored in the drain tank 112. The drain tank 112 is periodically maintained and discarded.

  In addition, a method of drying by blowing high-speed air from both sides is known (for example, see Patent Document 2).

  Hereinafter, the hand dryer will be described with reference to FIGS. 42 and 43. FIG.

As shown in FIGS. 42 and 43, the main body 201 fixed to the wall surface is attached with a jet nozzle 202 that jets a high-speed jet facing the pair. A processing space 404 for inserting a hand into the space facing the ejection nozzle 202 and drying is formed in the main body. A water receiver 203 serving as a water droplet collecting means is attached below the processing space 404. A blower unit 205 and a control unit 207 are provided in the main body 201. Detection means 208 for detecting a hand inserted into the processing space 404 and energizing the blowing means 205 is attached to a part of the main body 201. When a wet hand is inserted into the processing space 404 in the above configuration, the presence of the hand is detected by the detection unit 208 and the air blowing unit 205 is operated. As a result, external air is sucked from the suction port 209 installed in the lower part of the main body, and wind is formed through the blowing means 205 and blown from the ejection nozzle 102. At this time, the hand hits the hand, and the hand is dried. When the hand is retracted, the detection means 208 is not detected, so the air blowing means 205 stops. Such operation is performed by the control means 207.

(Embodiment 1)
In the first embodiment of the present invention, as shown in FIGS. 1 to 4, the hand drying device 1 fixed to the wall surface has a nozzle portion 2 on the upper portion of the hand drying device 1, and a high-speed jet from the nozzle portion 2. A drying chamber 3 which is a water droplet collecting means installed in the jetting direction is attached. A processing space 4 for inserting a hand between the nozzle unit 2 and the drying chamber 3 and drying it is formed in a free space inside the hand dryer 1. In the hand dryer 1, a fan motor 5, a heat generating means 6 and a control means 7 are provided. A detection means 8 for detecting a hand inserted into the processing space 4 and energizing the fan motor 5 and the heat generation means 6 is attached to a part of the hand dryer 1. A drying chamber 3 is installed above the fan motor 5, and the nozzle unit 2 is located above the drying chamber 3.

  When a wet hand is inserted into the processing space 4 in the above configuration, the presence of the hand is detected by the detection means 8 and the fan motor 5 and the heat generation means 6 are operated. Thereby, external air is sucked from the suction port 9 installed at the lower part of the main body, hot air is formed via the fan motor 5 and the heat generating means 6 and is blown from the nozzle part 2. At this time, warm air hits the hand that has been put out, and the hand is dried.

  The nozzle part 2 is installed in the stationary part 11 of the hand dryer 1 via the bearing 10, and the nozzle part 2 rotates around the rotating shaft 12 by the reaction force of the kinetic energy due to the high-speed jet from the nozzle part 2. It has a configuration. Therefore, the nozzle unit 2 is expressed as a rotating nozzle 13.

  The rotary nozzle 13 is connected to the bearing 10. The bearing 10 uses a seal and is configured to contact both sides of the high pressure portion 14 and the atmospheric pressure portion 15.

  The outer diameter of the bearing 10 is smaller than the outer diameter of the rotary nozzle 13, and a flow path is provided so as to pass through the inner ring side of the bearing 10.

  The rotary nozzle 13 is made of a moldable synthetic resin.

  The rotary nozzle 13 has at least one slit-like or porous jet generating part 16, and the jet generating part 16 changes the location with the rotation of the rotary nozzle 13. When the hand is retracted, the detection means 8 is not detected, so the fan motor 5 and the heat generation means 6 are stopped. Such operation is performed by the control means 7. Accordingly, since the high-speed jet stops, the rotation of the rotary nozzle 13 also automatically stops.

  The jet generation unit installation surface 17 in which the jet generation unit 16 is installed on the rotary nozzle 13 is not parallel to the rotation axis 12 of the rotary nozzle 13. Further, the rotating shaft 12 of the rotating nozzle 13 is not parallel to the floor surface.

  The force for driving the rotary nozzle 13 can be transmitted by setting the wind speed of the jet jetted from the jet generating section 16 to 70 to 120 m / s. When the wind speed is faster than 70 m / s, the rotary nozzle 13 becomes difficult to drive, and the rotational speed decreases. On the other hand, when the wind speed is higher than 120 m / s, the number of rotations increases too much, making it difficult to remove water droplets and reducing the drying effect.

  When the wind speed is faster than 120 m / s, the control blade 18 can be installed in a part of the rotary nozzle 13 to adjust the rotation speed.

  Further, when the wind speed is slower than 70 m / s, the rotary nozzle 13 is driven by the motor 19, or the flow path 20 for communicating air from the fan motor 5 to the rotary nozzle 13 is provided. If the rotation device 26 is provided in a part of the rotary nozzle 13 and the rotary nozzle 13 is driven, the rotary nozzle 13 can be rotated regardless of the wind speed of the jet.

  Since the rotating nozzle 13 has the balance adjusting unit 21 that adjusts the balance, unbalance can be prevented, so that generation of vibration can be prevented.

  Moreover, by providing the mesh on the inflow side of the jet generating section 16 provided in the rotary nozzle 13, it is possible to change the generation of the jet and reduce noise.

  Since the rotating nozzle 13 has left and right hands, it is more effective than a single installation if a plurality of the rotating nozzles 13 are arranged so as to be symmetrical. In this case, the rotating shafts 12 of the plurality of rotating nozzles 13 are installed in parallel.

  Since the rotation of the rotary nozzle 13 in the left and right directions can prevent interference between the jets of the left and right rotary nozzles 13, it is possible to prevent water droplets from being scattered.

  In addition, a stationary protective wall 22 is provided outside the rotary nozzle 13 so that the user can use it safely by making it difficult for the user to contact the rotary nozzle 13.

  The water droplets collected in the drying chamber 3 pass through the drain hole 23 in the drying chamber 3 and are stored in a certain amount in the drain tank 24. The drain tank 24 is regularly maintained, and the collected water droplets are discarded.

  The fan motor 5 is an electric blower generally used for a vacuum cleaner and 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.

  As shown in FIGS. 13 and 14, the drying chamber 3 can be installed at a position lower than the fan motor 5, and the installation method should be examined for the convenience of the configuration.

(Embodiment 10)
In the tenth embodiment of the present invention, the same parts as those in any of the first to ninth embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIGS. 15 to 18, the hand drying device 1 fixed to the wall surface or the floor surface has a processing space 4 for inserting a hand and removing attached water droplets. A drying chamber 3 is formed around the processing space 4 so that water droplets removed from the hand are not scattered outside. Further, the nozzle unit 2 is provided on two or more surfaces of the drying chamber 3, and a high-speed jet is ejected from the nozzle unit 2 toward the processing space 4. The hand dryer 1 is, for example, an electric blower generally used for a vacuum cleaner and the like, including 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 the fan motor 5 that feeds out and a control means 7 as a circuit board equipped with, for example, a PTC heater and a microcomputer as the heat generating means 6 are provided, when a hand is inserted into the processing space 4, the drying chamber The presence of a hand is detected by, for example, a detection means 8 using an infrared sensor provided in a part of 3 and a detection signal is sent to the control means 7. The control means 7 starts energization of the fan motor 5 and the heat generation means 6. When the detection means 8 no longer detects the user's hand, the detection signal is not sent to the control means 7, and the control means 7 performs control to stop energization of the fan motor 5 and the heat generation means 6.

  When a wet hand is inserted into the processing space 4 in the above configuration, the presence of the hand is detected by the detection means 8 and the fan motor 5 and the heat generation means 6 are operated. Thereby, external air is sucked from the suction port 9 installed at the lower part of the main body, hot air is formed via the fan motor 5 and the heat generating means 6 and is blown from the nozzle part 2. At this time, warm air hits the hand that has been put out, and the hand is dried.

  The nozzle part 2 is installed in the stationary part 11 of the hand dryer 1 via the bearing 10, and the nozzle part 2 rotates around the rotating shaft 12 by the reaction force of the kinetic energy due to the high-speed jet from the nozzle part 2. It has a configuration. Therefore, the nozzle unit 2 is expressed as a rotating nozzle 13.

  The rotary nozzle 13 is connected to the bearing 10. The bearing 10 uses a seal and is configured to contact both sides of the high pressure portion 14 and the atmospheric pressure portion 15. The outer diameter of the bearing 10 is smaller than the outer diameter of the rotary nozzle 13, and a flow path is provided so as to pass through the inner ring side of the bearing 10.

  The rotary nozzle 13 can be manufactured at a low cost by being formed of a moldable synthetic resin, and can be made lightweight.

  The rotary nozzle 13 has a diameter of 80 to 130 mm, for example, in accordance with the width of the hand, and has at least one or more jet-shaped generating portions 16 having a slit shape having a width of 1.5 to 2.5 mm or a porous shape having a diameter of 2 to 3 mm, The jet generating part 16 changes the location with the rotation of the rotary nozzle 13. When the hand is retracted, the detection means 8 is not detected, so the fan motor 5 and the heat generation means 6 are stopped. Such operation is performed by the control means 7. Accordingly, since the high-speed jet stops, the rotation of the rotary nozzle 13 also automatically stops.

  The jet generation part installation surface 17 in which the jet generation part 16 is installed in the rotary nozzle 13 is configured not to be parallel to the rotary shaft 12 of the rotary nozzle 13 and jets the jet in a single plane, and continuously jets the target. Can be applied. In addition, the rotation axis 12 of the rotary nozzle 13 is not parallel to the floor surface, so that it is easy to use for the user, for example, an angle of 10 to 30 degrees. Can be inserted.

  The force for driving the rotary nozzle 13 can be transmitted by setting the wind speed of the jet jetted from the jet generating section 16 to 70 to 120 m / s. When the wind speed is faster than 70 m / s, the rotary nozzle 13 becomes difficult to drive, and the rotational speed decreases. On the other hand, when the wind speed is higher than 120 m / s, the number of rotations increases too much, making it difficult to remove water droplets and reducing the drying effect.

  When the wind speed is faster than 120 m / s, the control blade 18 can be installed in a part of the rotary nozzle 13 to adjust the rotation speed. For example, the control blade 18 is installed perpendicularly to the rotation direction as shown in FIG. 18 so that when the rotary nozzle 13 rotates, it receives a wind and becomes a resistance. This is to adjust the rotation speed.

  Further, when the wind speed is slower than 70 m / s, the rotary nozzle 13 is driven by the motor 19, or the flow path 20 for communicating air from the fan motor 5 to the rotary nozzle 13 is provided. If a rotation device 26 using the action of a windmill that rotates by receiving wind, for example, is provided in a part of the rotary nozzle 13 and the rotary nozzle 13 is driven, the rotary nozzle 13 can be rotated regardless of the wind speed of the jet. Can do.

  Since the rotating nozzle 13 has the balance adjusting unit 21 that adjusts the balance, unbalance can be prevented, so that generation of vibration can be prevented. The balance adjusting unit 21 is used when the center of gravity of the rotating nozzle 13 does not overlap the rotating shaft 12. For example, a rib shape as the balance adjusting unit 21 is provided at a position opposite to the center of gravity of the rotating nozzle 13 with the rotating shaft 12 as the center. The imbalance is eliminated by providing a thick portion.

  Further, by providing the mesh on the inflow side of the jet generating section 16 provided in the rotary nozzle 13, it is possible to change the jet flow by generating a vortex before the jet generation, and to reduce noise. The mesh may be, for example, a 20-80 mesh stainless steel wire mesh or a resin plenet filter. In addition, as an installation method, it is effective to install perpendicularly to the direction in which the wind flows.

  Further, since the rotating nozzles 13 have left and right hands, if a plurality of the rotating nozzles 13 are arranged so as to be symmetric, it is more effective than a single installation. In this case, if the rotating shafts 12 of the plurality of rotating nozzles 13 are installed in parallel, it is easy to use and can insert a hand side by side.

  Since the rotation of the rotating nozzle 13 is reversed to the left and right, the interference of the jets of the left and right rotating nozzles 13 can be prevented, so that water droplets can be prevented from scattering.

  In addition, a stationary protective wall 22 is provided outside the rotary nozzle 13 so that the user can use it safely by making it difficult for the user to contact the rotary nozzle 13.

  The water droplets collected in the drying chamber 3 pass through the drain hole 23 in the drying chamber 3 and are stored in a certain amount in the drain tank 24. The drain tank 24 is regularly maintained, and the collected water droplets are discarded.
