Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a hand washing device used for washing hands.
In particular, the present invention relates to a hand washing device for use in a zero gravity space such as outer space.

[Conventional technology]

Nowadays, advances in space engineering have made it possible for humans to stay in outer space for long periods of time in a zero-gravity state. , a shower or hand-washing device that can be used in zero gravity will be required.

However, in space, where there is no gravity, the user's body floats, and the shower water becomes droplets and scatters all over the room, making it difficult to drain water because it does not flow down to one place. be.

In order to solve such problems, the present applicant et al.
We have developed and applied for a "shower device that can be used in zero gravity."

As shown in FIG. 3, this shower device used in a zero-gravity state includes a shower water spouting section 13 and a floating floor 15 made of a perforated plate inside a shower room 11 configured to maintain watertightness. A blower 17 that blows air toward the floating floor 15 is installed on the ceiling of the shower room 11, and a suction port that sucks the air that has passed through the holes in the floating floor 15 and shower water is installed on the bottom of the shower room 11. 19.

In such a shower device used in a zero-gravity state, the user is pressed against the floating floor 15 by the airflow generated in the shower room 11 even in the zero-gravity state, and the user is pushed against the floating floor 15 moderately as if gravity were acting. Fixed.

In addition, after the shower water spouted from the water spouting section 13 cleanses the user's body, it can be collected at the suction port 19 and drained together with the airflow without floating in the shower room 11, resulting in a zero gravity state. It becomes possible to take a shower at the bottom without any trouble.

[Problem to be solved by the invention]

However, such conventional shower devices used in zero gravity have a problem in that it is very difficult to remove shower water that has adhered to the body during a shower bath from the body.

That is, as a result of intensive research on the behavior of shower water on the body in a zero gravity state, the present inventors found that in a zero gravity state, water droplets adhering to the body adhere to the body in the form of a water film, and this water film is formed on the body. It was found that it was very difficult to peel it off.

This also holds true when washing your hands using a designated hand washing device; water droplets on your hands form a water film on your hands, and it is extremely difficult to remove this water film from your hands. becomes.

The present invention has been made based on this knowledge, and an object of the present invention is to provide a hand washing device for use in a zero-gravity space that can reliably remove a film of water from hands during hand washing.

[Means to solve the problem]

The hand-washing device for zero-gravity space of the present invention has a hand-washing container in which an internal space for hand-washing is formed, an opening for inserting a hand, and a water spout that spouts hand-washing water at a relatively low pressure into the hand-washing container. and a jet water jet ejecting means for ejecting a relatively high-pressure jet water stream toward a water film attached to the hand due to the discharge of the hand washing water and removing the water film from the hand. It is.

[Function] In the zero-gravity space hand-washing device of the present invention, when a hand is inserted through the opening of the hand-washing container, first, hand-washing water is spouted from the spouting part toward the hand at a relatively low pressure, and this hand-washing water washes the hand. Washing is performed, and then the water jet ejection means is activated to eject the water jet toward the water film that has adhered to the hand due to washing, and the water film is peeled off and removed from the hand.
