Hand dryer

Abstract

A hand drying apparatus less causing discomfortable blow back from an hand insertion opening in a hand drying compartment and spattering of water droplets around the apparatus and having excellent drying performance. The hand drying apparatus (1) comprises a box-like body housing (2), an electric blower (16) stored in the body housing, nozzle means (18), a ventilation opening (22), and a water droplet spattering prevention means (24). The body housing (2) is formed of a front member (4), a rear member (6), and side members (8), and a front side wall part (11), a rear side wall part (13), and a bottom part (14) forming the hand drying compartment (10) with the hand insertion opening (12) opening in the upper face thereof. The nozzle means (18) is installed at the front side wall part and the rear side wall part of the body housing and blowing airflow fed from the electric blower toward hands inserted into the hand drying compartment. The ventilation opening (22) is formed in the side of the body housing and ventilating the airflow in the hand drying compartment to the outside. The water droplet spattering prevention means (24) is installed in the ventilation opening and preventing water droplets in the hand drying compartment from spattering to the outside.

Description

technical field [0001] The present invention relates to a hand dryer, and more particularly to a hand dryer which dries a user's hand by blowing air. Background technique [0002] In recent years, in toilets or washrooms of public facilities such as railway stations, hotels, movie theaters, or large-scale commercial facilities, hand drying devices are installed that insert wet hands after washing and dry them with automatically blown airflow. This existing hand drying device is installed on the wall of the toilet or washroom. If wet hands are inserted from the opening provided on the upper surface, the built-in electric blower will automatically open and blow air flow into the drying room. The airflow dries while blowing off the water adhering to the hands (see Patent Documents 1 to 4).

AI Technical Summary

Problems solved by technology

[0014] However, in the inside of the drain hose connected to the drain outlet of the hand drying device described in Patent Document 1 and Patent Document 2, and in the circulation path of the hand drying device described in Patent Document 3 and Patent Document 4, there is adhesion Dirt in the respective internal drainage, and the problem of bad odor due to bacteria multiplying in the dirt

Even if you want to clean them, there is a problem that it is difficult to clean because the drainage hose and the circulation path are installed inside the hand dryer.

[0015] In addition, in the hand drying device described in Patent Document 2, the bottom portion on the deep side of the hand insertion portion is formed as an inclined surface toward the drain ports formed on both edge portions in order to recover drainage. The rising part is formed on the part, so in order to clean the dirt accumulated on the boundary part between the bottom part and the rising part, the dirt must be pulled out, and there is a problem that it takes time and dirt remains.
