1 and 2 are a perspective view and a longitudinal cross-sectional view showing the overall configuration of the present invention, Figures 3a and 3b is a front view and a rear view of the present invention.

As shown in the present invention, the inner case 2 is provided inside the case body 1, and the inner case 2 is provided with a hand opening 21 and a hand shower chamber 22 before and after. .

In addition, the outer side of the inner case 2, the air curtain nozzle (3) forming an air curtain in the hand opening 21, and the sensor 6 for detecting whether the hand is inserted into the inner case (2) And lower and upper air shower nozzles 4 and 4A for injecting air into the hand shower chamber 22 and disinfecting the hand inserted into the hand shower chamber 22 of the inner case 2. UV lamp 7 is provided.

In addition, the lower side of the inner case 2 is provided with a discharge part 23 for discharging the air injected into the hand shower chamber 22 to the outside atmosphere, and the air curtain nozzle 3 and the upper and lower air showers. An air supply line 5 is provided for supplying the filtered air to the nozzles 4 and 4A.

As shown in FIG. 4, the air supply line 5 continuously supplies air filtered with particles to the air curtain nozzle 3 and the upper and lower air shower nozzles 4A. After the air supply through line 51 is interrupted, the particles that are not filtered are filtered through a separate air filter 52B and then the air curtain nozzle 3 and the upper and lower shower nozzles 4 ( It is composed of an emergency supply line 52 for supplying to the 4A) side.

In addition, the continuous supply line 51 and the emergency supply line 52 is connected to the branch line 53 connected to the air curtain nozzle 3 and the upper and lower air shower nozzles 4 and 4A, respectively, the branch An open / close valve 54 is provided between the line 53 and the constant supply line 51, and the emergency supply line 52 is provided with a ball valve 52A.

On the other hand, the inner case 2 is formed in a narrow space enough to insert the hand in the hand opening 21 to minimize the outflow of particles, the hand shower chamber 22 is free to move the hand It is formed into a large space.

Further, an inclined surface 24 is formed in the inner case 2 between the hand inlet 21 and the hand shower chamber 22 toward the hand shower chamber 22, and the lower air shower nozzle 4A is formed on the inclined surface 24. This is installed.

5a to 6b are perspective views showing the structure of the air curtain nozzle and the air shower nozzle of the present invention.

The air curtain nozzle 3 is vertical as shown in FIGS. 5A and 5B having a plurality of fastening holes 32A on the rear upper side of a horizontal air discharge surface 31 having a plurality of injection holes 31A. The fixing surface 32 is integrally formed, and the inlet support surface 33 having a plurality of air inlets 33A is provided at the front side of the air discharge surface 31 toward the lower side of the fastening hole 32A of the fixing surface 32. It is integrally formed obliquely.

The upper and lower air shower nozzles 4 and 4A have a plurality of fixed surfaces 42 formed with a plurality of injection holes 42B between the fastening holes 42A on both sides, as shown in FIGS. 6A and 6B. An inlet support surface 33 having an air inlet 43A is formed to be inclined, and the inlet support surface 33 is integrally formed to be supported by the support surface 41.

Next will be described in detail the operation of the present invention configured as described above.

First, when the worker puts his hand in the hand opening 21, the detection sensor 6 detects this and turns on the UV lamp 7, and at the same time, opens the on-off valve 54 to always supply line 51 and branch. The outside particles are filtered through line 53 and supplied to the air curtain nozzle 3 and the upper and lower air shower nozzles 4 and 4A.

Accordingly, the air curtain nozzle 3 injects air into the hand inlet 21 to form an air curtain, and the upper and lower air shower nozzles 4 and 4A inject air into the hand shower chamber 22. By drying the hand, UV lamp 7 is to sterilize the hand.

At this time, the hand shower chamber 22 is formed as a large space to move the hand, whereas the hand opening 21 is formed in a narrow space that can be inserted into the hand shower chamber 22 In addition to minimizing the outflow of the air and particles injected into the), it is blocked from the outside by the air curtain formed in the hand opening 21.

Then, the lower air shower nozzle 4A is installed on the inclined surface 24 formed in the inner case 2 so as to face the hand shower chamber 22 so as to eject air so that the spray angle and the position of the hand coincide. Therefore, the hand can be dried more quickly and efficiently without loss of air, and the air containing particles inside the hand shower room 22 is discharged to the outside air through the discharge unit 23.

When the sterilization and drying of the hand is completed and the hand is removed from the hand opening 21, the detection sensor 6 detects this, turns off the UV lamp 7, and closes the on / off valve 54 at all times. When the supply of air through the line 51 and the branch line 53 is cut off and the hand is inserted into the hand inlet 21 again, the UV lamp 7 is turned on again, and the on-off valve 54 is opened. The supply of air to the air curtain nozzle 3 and the upper and lower air shower nozzles 4A is repeated.

However, if the supply of air through the constant supply line 51 and the branch line 53 is stopped due to an abnormality of an external device or the like even when the open / close valve 54 is opened, the ball valve 52A of the emergency supply line 52 is provided. Air is flowed through the emergency supply line 52 by opening the air) through the emergency supply line 52, and the air flows through the air filter 52B through the pure air branch line 53 from which particles are removed. It is supplied to the nozzle 3 and the upper and lower air shower nozzles 4 and 4A to sterilize and dry the hands by the UV lamp 7, and supply air through the constant supply line 51. When this is done, the ball valve 52A is closed again, thereby performing normal operation.

On the other hand, the air curtain nozzle 3 of the present invention is fixed to the inner wall of the case body 1 through the fastening hole 32A of the fixing surface 32, as shown in Figure 2 and 5a and 5b, Branch lines 53 are connected to the air inlet 33A of the support surface 33, and both ends of the nozzle are closed by both inner surfaces of the case body 1.

At this time, the inlet support surface 33 is integrally formed in the lower portion of the fastening hole (32A) of the fixed surface 32, a plurality of air inlet 33A is provided at a predetermined interval over the entire width to install the nozzle Since the air shower nozzles 4 and 4A are similar to the air curtain nozzles 3, the upper and lower air shower nozzles 4 and 4A are similar to the air curtain nozzles 3, so that the air can be sprayed evenly and more effectively. Shall be.
