Definitions

  • the present invention relates to a hand dryer that hygienically performs a drying process by jetting a high-speed airflow onto wet hands after having been washed.
  • a hand dryer has been developed that hygienically performs a hand drying process, in which wet hands after having been washed are dried by blowing water away by jetting high-speed airflow, rather than being wiped on a towel or a handkerchief.
  • a hand dryer is disclosed that is provided with two air nozzle sections that jet high-speed airflows (for example, see Patent Document 1).
  • the two air nozzle sections are provided on a near side and a far side of an opening of a hand drying chamber to face each other. Wind is simultaneously applied to both a palm and a back of a hand, so that water is blown away from the hand, thereby drying the hand.
  • a hand dryer has a hand drying chamber including a hand insertion opening, a first wall section, a second wall section, and a pair of air nozzles.
  • a left hand and a right hand can be inserted in parallel into the hand insertion opening.
  • the first wall section faces backs of the left hand and the right hand that are inserted in parallel from the hand insertion opening.
  • the second wall section faces palms of the left and the right hand, and the first wall section.
  • the pair of air nozzles is arranged in respective centers of the first wall section and the second wall section to extend roughly along an overall length of the hands, almost in parallel with a direction of fingers of the left hand and the right hand inserted in parallel.
  • the pair of air nozzles respectively jet high-speed airflows to the left and to the right to be almost parallel with the backs and the palms of the left hand and the right hand (for example, see Patent Document 2).
  • Patent Document 1 is problematic in that the high-speed airflows jetted from the two opposing air nozzle sections collide with each other. Therefore, a disruption occurs in the airflows, thereby causing noise.
  • Patent Document 2 The hand dryer disclosed in Patent Document 2 is problematic in that the pair of air nozzles respectively jet the high-speed airflows to the left and to the right to be roughly parallel with the palms and backs of the left hand and the right hand.

  • a hand drying chamber 2 is formed in an upper portion of a main body casing 1 .
  • the hand dryer 81 is used by fixing the main body casing 1 onto a wall surface, such as that of a rest room, through use of a screw and the like.
  • a second wall section 3 is formed on an upper front side (user side) of the main body casing 1 .
  • a first wall section 4 is formed on an upper back side.
  • the hand drying chamber 2 is surrounded by an inner surface 5 of the second wall section 3 , an inner surface 6 of the first wall section 4 , and a bottom surface 8 .
  • the bottom surface 8 receives water droplets blown from hands.
  • a hand insertion opening 9 is formed in an upper portion of the hand drying chamber 2 . Hands are inserted into and removed from the hand insertion opening 9 .
  • Lateral opening sections 10 are formed in both lateral directions. The lateral opening sections 10 allow air to flow out after a hand drying process.
  • a high-pressure airflow generating unit 11 is arranged in a lower portion of the main body casing 1 . High-pressure airflows generated by the high-pressure airflow generating unit 11 are led to air nozzle sections 13 provided on the first wall section 4 , by way of an airflow path 12 formed in the first wall section 4 .
  • the hands of a user are inserted into the hand drying chamber 2 at an angle, such that wrists are on a near side and fingertips are on a far side (rear side), in a state in which a left hand and a right hand of the user standing in front of the main body casing 1 are naturally aligned in parallel in a lateral direction.
  • the air nozzle sections 13 are formed (set) projecting from the inner surface 6 of the first wall section 4 , in positions respectively facing the left hand and the right hand that are inserted into the hand drying chamber 2 .
  • Longitudinal directions of the air nozzle sections 13 extend to be almost parallel with directions of respective fingers of the hands inserted in the vertical direction.
  • the air nozzle sections 13 are formed at a forward-tilt angle of 5 degrees to 45 degrees, such that upper portions are on the near side and lower portions are on the far side (rear side).
  • the direction of a finger is approximately a direction of a middle finger when the hand is naturally spread.
  • the inner surface 5 of the second wall section 3 is formed at a forward-tilt angle, such that the hands can be easily inserted into the hand drying chamber 2 and a distance from the air nozzle sections 13 is almost constant.
  • the hand dryer 81 is configured such that high-speed airflows 14 (wind speed: 50 m/s to 250 m/s) are jetted into the hand drying chamber 2 from the air nozzle sections 13 .
  • High-speed airflows 14 (wind speed: 50 m/s to 250 m/s) are jetted into the hand drying chamber 2 from the air nozzle sections 13 .
  • Water on the left hand and the right hand, inserted into the hand drying chamber 2 is blown towards the inner surface 5 of the second wall section 3 .
  • the water droplets that have been blown are collected on the inner surface 5 of the second wall section 3 and the bottom surface 8 .
  • the collected water droplets then pass through a drain 15 and a drain pipe 16 , and are collected in a drain tank 17 .
  • the drain tank 17 can be attached and removed freely to and from the main body casing 1 by being slid forward and backward.
  • a removal lid covers the drain tank 17 .
  • the high-pressure airflow generating unit 11 includes a DC brushless motor (alternatively, an ordinary commutator motor or an induction motor can also be used), a motor driving circuit, and a turbo-fan driven by the DC brushless motor.
  • the high-pressure airflow generating unit 11 is automatically operated by a control circuit 18 .
  • An air inlet 19 of the high-pressure airflow generating unit 11 opposes an inlet passage 20 provided within the main body casing 1 .
  • the air inlet 19 suctions external air from a suction opening 21 on a lower end of the inlet passage 20 .
  • a filter 25 removes dust and moisture from the air suctioned from the suction opening 21 .
  • the air is then supplied to the high-pressure airflow generating unit 11 .
  • a hand detecting sensor 22 is provided on the inner surface 6 of the first wall section 4 . Whether the hands are inserted into the hand drying chamber 2 from the hand insertion opening 9 is detected by a detection signal from the hand detecting sensor 22 .
  • the detection signal from the hand detecting sensor 22 is input into the control circuit 18 that includes a microcomputer.
  • the control circuit 18 judges that the hands are inserted, the control circuit 18 electrifies the high-pressure airflow generating unit 11 to jet the high-speed airflows 14 from the air nozzle sections 13 .
  • the hand detecting sensor 22 detects insertion of the hands.
  • the high-pressure airflow generating unit 11 operates under the control of the control circuit 18 .
  • the high-speed airflow 14 is jetted from the air nozzle section 13 obliquely downward, towards a front side of the hand drying chamber 2 .
  • FIG. 3 is a side view of when the hands are inserted into the hand dryer according to the first embodiment and twisted.
  • FIG. 4 is a longitudinal cross-sectional view of relative positions of the air nozzle sections of the hand dryer according to the first embodiment and the inserted hands. As shown in FIG. 3 and FIG. 4 , when the hands are twisted front and back, such that the palms are turned by flipping the wrists, the high-speed airflows 14 jetted from the air nozzle sections 13 come into contact with the entire hands and pass between the fingers, blowing water from the hands.
  • FIG. 5 is a transverse cross-sectional view taken along line A-A in FIG. 1 .
  • the high-speed airflows 14 that have come into contact with the hands, passed between the fingers, and blown the water droplets change directions of flow after coming into contact with the inner surface 5 of the second wall section 3 .
  • the high-speed airflows 14 then flow outside from the lateral opening sections 10 .
  • the blown water droplets are separated from the airflow by inertia force, because of the change in the direction of flow of the high-speed airflows 14 .
  • the water droplets run down the inner surface 5 of the second wall section 3 and the bottom surface 8 , and are collected by the drain 15 (see FIG. 2 ).
  • the water droplets then pass through the drain pipe 16 and are collected in the drain tank 17 .
  • the second wall section 3 blocks the high-speed airflows 14 in front of the user. Therefore, the user is not exposed to the high-speed airflows 14 and the water droplets.
  • the hand detecting sensor 22 detects that the hands have been removed and stops the high-pressure airflow generating unit 11 .
  • the air nozzle sections 13 will be explained in detail.
  • the hands of the user are inserted into the hand drying chamber 2 at an angle, such that the wrists are on the near side and the fingertips are on the far side (rear side), in a state in which the left hand and the right hand of the user standing in front of the main body casing 1 are naturally aligned in parallel in the lateral direction.
  • the air nozzle sections 13 extend in the vertical direction on the first wall section 4 that faces each hand inserted into the hand drying chamber 2 .
  • the air nozzle section 13 is arranged at a frontward tilt angle such that the upper portion is positioned towards the front side and the lower portion is positioned towards the far side (rear side).
  • the high-speed airflows 14 jetted from the air nozzle sections 13 flow from the far side of the hand drying chamber 2 towards the near side, advancing obliquely downward, in a shape of an air curtain extending in the vertical direction.
  • the high-speed airflows 14 come into contact with the entire hands at the same time, from the wrist to the fingertips of each hand.
  • the high-speed airflows 14 also pass between the fingers. Therefore, when the front and the back of the hands are placed in contact with the high-speed airflows 14 by twisting the hands at the wrist, water on the front and the back of the hands and between the fingers are blown. Therefore, the entire hands can be dried without moving the hands in the vertical direction.
  • the air nozzle sections 13 are respectively arranged in positions opposing the left hand and the right hand inserted into the hand drying chamber 2 . Therefore, the distance between the hand and the air nozzle section 13 can be shortened.
  • the air nozzle section 13 is arranged at a forward-tilt angle such that the upper portion is positioned towards the near side and the lower portion is positioned towards the far side. Therefore, the distance between the hand and the air nozzle section 13 is almost constant from the wrist to the fingertips.
  • the high-speed airflow 14 comes into contact with the entire hand at a constant speed, without reduction in flow rate and while maintaining high kinetic energy. Thus, water is efficiently and evenly removed from the hands.
  • Air jet openings 24 of the air nozzle sections 13 face downward. Therefore, the water droplets within the hand drying chamber 2 are prevented from entering the main body casing 1 from the air jet openings 24 .
  • the air nozzle sections 13 are provided only on the first wall section 4 side. No air nozzles are arranged on the second wall section 3 side. Therefore, collision between the jetted high-speed airflows 14 does not occur, so that noise caused by collision between high-speed airflows does not occur. Thus, the hand dryer 81 makes less noise.
  • the high-speed airflow 14 is jetted obliquely downward and blows the water droplets in a direction along gravitational force. Therefore, water on the hands can be efficiently removed. Moreover, airflow after the hands are dried is also obliquely downward. As shown in FIG. 3 , the air flows from the hand drying chamber 2 downwards to the lateral opening sections 10 , and does not flow out of the hand insertion opening 9 . Therefore, the user is minimally exposed to wind and water droplets.
  • an angle formed by a pair of the air nozzle sections 13 is set to 0 degree to 60 degrees (a V-shape of about 20 degrees for an ordinary adult person) so that space between a pair of the air nozzle sections 13 in the lateral direction is formed to be large on a hand insertion side and small on the far side.
  • the angle formed by the left hand and the right hand, and the angle formed by a pair of the air nozzle sections 13 match.
  • the high-speed airflows 14 come into contact with the entire hands and between the fingers, resulting in high water-removal performance.
  • the hand dryer 81 because a pair of the air nozzle sections 13 does not oppose each other, the high-speed airflows come into contact with every part of the hands while maintaining wind speed. Because the air nozzle sections 13 extend in the vertical direction, as shown in FIG. 5 , the jetted high-speed airflows 14 enter gaps between the fingers. Thus, water on the side surfaces of the fingers can be efficiently removed.

  • FIG. 7 is a diagram of a modified example of the air jet opening.
  • FIG. 8 is a diagram of another modified example of the air jet opening.
  • FIG. 9 is a diagram of still another modified example of the air jet opening.
  • FIG. 10 is a side view of a modified example of the air nozzle section.
  • the long hole-shaped air jet openings 24 are successively arranged in a row forming a broken line.
  • the air nozzle section 13 achieves excellent drying performance and noise performance.
  • the air jet opening can be a slit-shaped air jet opening 24 a .
  • round hole-shaped air jet openings 24 b can be successively provided in a row forming a broken line.
  • the long hole-shaped air jet openings 24 can be successively arranged in a plurality of rows forming broken lines.
  • the air nozzle section 13 is not necessarily required to be integrally formed.
  • a plurality of air nozzle sections 13 a can be successively arranged in a row forming a broken line.
  • a length of each row of the air jet openings 24 , 24 a , and 24 b is a length from the wrist of the hand to the tip of the middle finger or longer (150 mm or more according to the first embodiment), such that the high-speed airflow comes into simultaneous contact with the entire hand. Thus, water can be efficiently removed.
  • the air nozzle section 13 is formed to project from the inner surface 6 of the first wall section 4 of the hand drying chamber 2 so that the distance between the hand and the air nozzle section 13 is made small. Moreover, areas of the hand insertion opening 9 and the lateral opening sections 10 are made large. As a result, the wind speed of the air flow including the water droplets flowing from the hand drying chamber 2 decreases. Thus, an amount of water droplets flowing out of the hand drying chamber 2 can be reduced.
  • the air nozzle section 13 is formed to project from the inner surface 6 of the first wall section 4 . Therefore, the first wall section 4 does not block view, so that an interior of the hand drying chamber 2 can be viewed from above the hand drying chamber 2 . Thus, a degree to which the hands are dried is easily visible.
