Abstract

PURPOSE:To easily turn ON or OFF for the generation of air bubbles by a bather in a household bath and to freely increase/decrease the generating quantity of the air bubbles by fitting a packing to interrupt air to be sucked from a hole part to the base edge of an operating cylinder and adjusting air quantity to be mixed in at the exit side of an orifice by the forward/backward movement of the operating cylinder. CONSTITUTION:For a hot water supplying port 7 to return purified hot bath water to the inside of a bathtub 1, the flow velocity of the hot bath water to flow in is increased at the exit side of an orifice 18 having a diameter smaller than that of a line 9D by the orifice 18, and the hot bath water is made into a jet stream and vigorously discharged in the bathtub 1. At this time, when a knob part 22A protruding in the bathtub 1 is rotated, and an operating cylinder 22 is moved, a packing 23 contacted with a hole part 21 by pressing is separated from the hole part 21, the air flows in toward the jet stream of the hot bath water at the exit side of the orifice 18, and while the jet stream rolls and mixes the air in itself, the jet stream generates a large quantity of fine air bubbles having a massaging effect and ultrasonic waves accompanying the generation of the air bubbles in the hot bath water. The generating quantity of these air bubbles and ultrasonic waves can be adjusted by adjusting the air quantity according to the rotating way of the operating cylinder 22.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bathing device that generates a jet of air bubbles in a bathtub for ordinary households so that the bathtub can be comfortably bathed.

[Conventional technology]

In recent years, air bubble jets, which mix air into the bathtub and forcefully eject it, are good for your health due to the synergistic effect of the ultrasonic waves generated by air bubbles and the pine surge effect, making bathing more comfortable. Bathing devices that generate .

However, in conventional devices of this type, the amount of bubbles generated cannot be adjusted from within the bathtub.

[Problem to be solved by the invention]

However, in ordinary home baths, people do not enter the bathtub frequently all the time, and continuing to emit jets of air with bubbles even when they are not taking a bath is a way of stirring the hot water in the bathtub and lowering the temperature. This was uneconomical, and the energy required to drive the pump and forcibly send the air was wasted. Furthermore, there is a problem in that the amount of bubbles generated cannot be adjusted at any time according to the bather's preference, making it inconvenient to use.

The present invention has been developed based on the above circumstances, and allows a bather in a home bath to easily turn on and off the generation of bubbles, as well as freely adjust the amount of bubbles generated, thereby reducing wasted energy. The purpose is to provide a bathing device that allows comfortable bathing without having to do anything.

[Means to solve the problem]

To achieve the above object, the bathing device of the present invention purifies and heats hot water in the bathtub while circulating it to the outside, and the bathing device has a narrow flow path inside a hot water cylinder attached to the hot water supply opening of the bathtub. An orifice is formed, a hole reaching the outside is opened in the wall on the outlet side of the orifice, and an operating cylinder having an inner diameter larger than the orifice is screwed into the hot water supply cylinder so that it can move forward and backward from the orifice exit side. The tip is made to protrude into the bathtub, and a packing is attached to the proximal end of the operation tube so as to be able to block air entering from the hole.

[For production]

In the bathing device configured as described above, purified bath water flows into the hot water cylinder, but at this time, the flow rate becomes faster at the exit side of the orifice where the flow path is narrow, and when passing through this orifice, it becomes a jet stream and flows into the hole. It sucks in the air that enters the bathtub, mixes the air, and generates minute bubbles that are forcefully discharged from the inside of the operating tube into the bathtub. In addition, by turning the operating tube that protrudes into the bathtub, you can adjust the gap width between the wall surface on the orifice outlet side and the packing, so it is possible to adjust the amount of air caught in the jet flow, and the packing of the operating tube can be adjusted to the orifice outlet. If you turn it until it comes into pressure contact with the side wall surface, the inflow of air will be blocked and the generation of air bubbles can be prevented.
