Abstract

<P>PROBLEM TO BE SOLVED: To provide an arrangement to a hand drier for keeping an enough space at the time of insertion of hands, and making a nozzle jet port and hands closer, in order to settle the problems the conventional drier has, where, hands might touch a nozzle or a hand drying chamber if only a minimum space is in the drier, and might damage a feeling of cleanliness, resulting in a longer hour of drying due to the wide space required between the nozzle jet port and hands. <P>SOLUTION: A jet nozzle 8 for generating jet is arranged in the direction to hand insertion. Insertion port of the drying chamber 3 can be arranged irrespective of a mounting position of the jet nozzle 8, so that an opening width of an insertion port is arranged relatively big for hands. Therefore, hands can be inserted and drawn to and from the drier smoothly. In addition, in this close space arrangement of hands and jet nozzle 8, kinetic energy of a jet can be effectively used, and a jet from jet nozzle 8 is not close to the opening to which hands are inserted. So, scattering of water drop is less caused by the jet blown against hands. <P>COPYRIGHT: (C)2005,JPO&NCIPI

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 device has been known to be dried by high-speed air (see, for example, Patent Document 1 or Patent Document 2).

  Hereinafter, the hand dryer will be described with reference to FIG.

  As shown in the figure, the main body 101 fixed to the wall surface is composed of a front case 102 and a water tray 103 protruding from the lower part, and a drying space 102 a is formed between the front case 102 and the water tray 103. . The front case 102 is provided with an air blower 104, a heat generating means 105, and a control means 108. At the lower end of the front case 102, the air blowing nozzle 106 faces the drying space 102a and faces the water receiving tray 103. It is installed to blow. Further, a detection means 110 for detecting a hand put out in the drying space 102a is provided in the vicinity of the blow-off nozzle 106, and the control means 108 receives the detection signal from the detection means 110 and turns on the blower 104 and the heat generation means 105. Drive control. In addition, protruding walls 107 are formed on the front and left and right sides of the water tray 103.

  When a wet hand is inserted into the dry space 102 a in the above configuration, the detection unit 110 detects the warm hand, and hot air is formed by the blower 104 and the heat generation unit 105 and is blown from the blowout nozzle 106. At this time, warm air hits the hand that has been put out, and the hand is dried. When the hand is withdrawn, the detection means 110 is not detected, so the blower 104 and the heat generation means 105 are stopped.

  In addition, water drops away from the hand are collected in the water receiving tray 103, but are easily scattered by the air blown by the air blowing nozzle 106. Therefore, the front and side protruding walls 107 of the water receiving tray 103 prevent scattering to the surroundings. It was something to do.

Further, in the air blowing path that seals the air blowing device 104 by the fixed cover 111 that fixes the air blowing device 104, the air blowing nozzle 106, and the separation cover 113 that separates the suction space 112 and the air blowing device 104, and connects all the components. It constituted a high static pressure state that was raised above atmospheric pressure.
