Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a hand drying device that suppresses the dispersion of water droplets and the like that fly off the hands due to the blown air current, and also facilitates cleaning of the device.

Conventional technology In conventional hand drying equipment, if the drying space has a plate-like periphery, water droplets, etc. fall onto the bottom surface of the drying space and are scattered on the front of the equipment due to the airflow. There was a need to always place the dryer on the lower surface of the drying space to absorb water droplets and the like.

In addition, in a high-speed airflow type hand drying device, if the airflow into the drying space is 30 m/s or more, in addition to the phenomenon of drying the moisture as a drying system, there is also a phenomenon of blowing away substances on the hands. Along with water droplets, waste products such as soap and dirt from washing were scattered from the hands, forming a semi-liquid state that adhered to the surrounding area.

In addition, if the drying space is surrounded by a perforated board such as a punched board, scattered objects will adhere to the outer periphery and bottom of the drying space, causing rust on screws and damaging electrical components. However, this was a cause of a decrease in insulation properties.

Furthermore, in conventional equipment, the peripheral wall that forms the drying space is often integrated with the casing of the equipment body, making it difficult to remove. Since only work can be done, it is difficult to remove waste materials that have entered the bends in the corners of the drying space.In devices with perforated plates around the drying space, they can be scattered over a wide area inside the device, making cleaning difficult. The work is difficult, and if left as is, waste products accumulate and become a source of bacteria and odor.

Purpose of the invention In order to prevent these problems, the present invention places a perforated plate only on the lower surface of the drying space of the hand dryer, and with the blowing airflow, the scattered objects are sucked into the lower surface of the drying space and fall. A made tray is arranged to collect the liquid in one place by the collision effect, and the drying space forming material and the tray are individually fixed with knurled screws, etc., so that they can be easily removed without tools and washed with water. The purpose is to make cleaning work easier and more complete.

Structure of the invention To explain the invention with reference to figures, Fig. 1 is a sectional view of a hand drying device according to this invention, Fig. 2 is a sectional view of a hand drying device according to this invention incorporating a high-performance filter, and Fig. 3 is a sectional view of a hand drying device according to this invention in which a high-performance filter is incorporated. The figure is a cross-sectional view of a free-standing hand dryer according to this invention, in which a stainless steel perforated plate 6 is arranged only on the lower surface of the drying space D, and this part is used as an inlet for the air flow R. At the same time, it serves the role of attracting flying liquids. A saucer 10 is arranged at the bottom of the perforated plate 6, and the airflow R flows from the side surface between the tray 10 and the perforated plate 6 in a different direction, but the liquid hits the tray 10 due to inertia. It is collected here.

The side wall 5 and perforated plate 6 surrounding the drying space are one piece and are fixed to the main body casing 1 by knurled screws 7, etc., and the saucer is similarly fixed independently and can be easily removed for cleaning etc. is becoming possible.

In addition, in the normal installation position, the saucer 10 is placed within the irradiation range of the germicidal lamp 4, and the saucer 10 is placed within the irradiation range of the germicidal lamp 4.
It has also started to have a bactericidal effect on waste products that have accumulated in the air.

Fig. 4 is a sectional view of a conventional hand drying device, Fig. 5 is a sectional view of a conventional hand drying device incorporating a high-performance filter, and Fig. 6 is a sectional view of a conventional free-standing hand drying device. Then, the airflow R discharged from the air outlet 9 hits the inserted hand and blows off water droplets, etc., and the fallen waterdrops 8 accumulate on the lower surface of the drying space D, and are further flowed out of the device or diffused into the inside of the device by the airflow R. Ru.

Effects of the invention With this invention, by sucking and circulating the high-speed airflow directly through the perforated plate at the bottom of the drying space, nearly 90% of the liquid that had been spread over a wide area is collected in the receiving tray. The diffusion prevention effect was great.

In addition, since it is removable, it is easy to clean and can be washed completely with water, making it possible to clean every nook and cranny, which improves the sanitary effect, and also helps prevent insulation deterioration and rust formation, which has a safety effect. I got excited.
