Description

The present invention relates to a mist bather that enables mist bathing.

Conventionally, there is known a bather configured so that even a person who has difficulty in bathing in a normal bathtub (for example, an elderly person or a person with a physical disability) can take a bath. As this type of bathing device, there are known various types of bathing devices, such as a shower bathing device and a simple bathing device equipped with a capsule-type bathtub that can be opened and closed, and one of them is hot water. There is known a mist bather which does not have a bathtub for uselessness and instead has a mist ejection part for ejecting mist.

For example, Japanese Patent Application Laid-Open No. 2005-224421 (Patent Document 1) describes the washing and drying of the body in the washing tank while configuring the device so that the body excluding the head of the bather can be accommodated in the box-shaped washing tank. A body washer / dryer as a mist bather configured to perform the above is disclosed.

More specifically, in the body washing / drying device disclosed in Patent Document 1, an entrance / exit is provided across the front surface and the upper surface of the washing tank, and a seat portion is provided in the washing tank for further washing. A shutter is provided at the entrance and exit of the tank so that it can be pulled out from below to above. In addition, hot water outlets are provided on the left and right inner wall surfaces of the cleaning tank and the surface of the seat, and hot air outlets are provided on the rear side wall surface of the cleaning tank.

As a result, the shutter is closed while the bather who has entered the washing tank through the doorway is seated on the seat, so that the body excluding the bather's head is accommodated in the washing tank, as described above. The hot water is ejected from the hot water outlet to enable mist bathing, and then the warm air is blown from the hot air outlet to dry the body.

As shown in FIG. 13, the front upper mist ejection portion 21 is composed of a spray unit 26 including a base member 27 and three nozzles 28, and in a state where the spray unit 26 is assembled, this is an inner shell 10B. By being assembled to the inner wall surface 19, the front upper mist ejection portion 21 is provided on the inner wall surface of the front wall 11 of the housing 10.

More specifically, the base member 27 is composed of a box-shaped member having a concave surface 27a facing the inside of the bathing device main body 2 after assembly and a frame-shaped portion located around the concave surface 27a. The concave surface 27a is provided with three through holes, and nozzles 28 are fixed to the base member 27 so as to insert the three through holes. As a result, the three nozzles are arranged on the concave surface 27a of the base member 27 so as to be separated from each other in the left-right direction.

A step portion 27b is provided at the outer peripheral end of the frame-shaped portion of the base member 27. The step portion 27b has a shape and size corresponding to the opening 19a provided on the inner wall surface of the inner shell 10B. Therefore, the pre-assembled spray unit 26 is assembled to the inner wall surface of the inner shell 10B so that the stepped portion 27b of the base member 27 is inserted into the opening 19a, so that the front upper mist ejection portion 21 is housing. It will be provided on the inner wall surface of the front wall 11 of 10.

The contact portion between the base member 27 and the inner shell 10B is sealed. The sealing process can be performed by applying a sealing agent, installing an O-ring, or the like.

Here, if a plurality of types of base members 27 having different inclination angles of the concave surface 27a, different numbers and positions of through holes provided in the concave surface 27a, and the like are prepared, a common nozzle 28 can be used. While using the nozzle 28, it is possible to easily manufacture a plurality of types of spray units 26 having different directions of the ejection shaft 28a of the nozzle 28. Furthermore, if nozzles 28 having different specifications are prepared, various ejection units can be easily manufactured by combining them.

On the other hand, each of the front upper end mist ejection portion 21, the front middle stage mist ejection portion 22, the front side lower stage mist ejection portion 23, and the rear side mist ejection portion 24 is not composed of the above-mentioned spray unit 26, but instead of the so-called spray unit 26. By using insert molding, it is possible to integrate the plurality of nozzles 28 included in the mist ejection portions 21 to 24 with the inner shell when molding the inner shell 10B.

When insert molding is used in this way, it is not necessary to provide the base member 27 described above, so that the device configuration can be simplified and the number of parts can be reduced, and the spray unit 26 can be attached to the inner shell 10B. Since it is not necessary to assemble and the above-mentioned sealing process is also unnecessary, the assembling work can be greatly simplified. Therefore, with such a configuration, it is possible to dramatically reduce the manufacturing cost.

14 and 15 are a schematic cross-sectional view and a schematic plan view showing a mist spraying area by a mist ejection portion of the mist bather according to the present embodiment, respectively.
