Description

Description: FIELD OF THE INVENTION The present invention relates to a bubble-generating device for a bathtub.

2. Description of the Related Art In recent years, even in a bath for home use, a bubble bath for the purpose of comfortably bathing a jet of water and bubbles in the bath water has been introduced.

FIG. 2 shows a conventional bubble-generating device for a bathtub. Reference numeral 1 is a bathtub, 2 is a suction port, and 3 is a jet port.
Reference numeral 4 denotes a heat exchanger for heating the bath water, which is connected to the suction port 2 and the jet port 3 of the bath 1 through circulation pipes 2a and 3a. Reference numeral 5 denotes a circulation pump for circulating the bath water, which may be attached to either the front side or the rear side of the heat exchanger 4 in the circulation line. Reference numeral 6 denotes an air blowing pipe, which is provided in front of the ejection port 3 and in the circulation pipe 3a after the circulation pump 5 is ejected. A nozzle 7 is attached between the air blowing pipe 6 and the jet port 3.

The operation of the bubble generating device configured as described above will be described below.

The bath water blown from the suction port 2 by the circulation pump 5 is heated by the heat exchanger 4. The heated circulating water is jetted into the bathtub 1 from the jet port 3 by the circulation pump 5. At this time, the circulating water jetted by the circulating pump 5 passes through the nozzle 7 to increase the speed. Then, the contact portion of the air blowing pipe 6 provided in front of the nozzle 7 with the circulating water becomes negative pressure, and the air is blown from here. Then, bubbles form in the circulating water and are ejected into the bathtub 1.

Problems to be Solved by the Invention However, in the above-mentioned configuration, in order to blow the air from the air blowing pipe 6 and further eject the air into the bathtub 1, the circulation pump 5 having a large capacity (about 300 W) is required,
The cost increases. Further, since air is blown in by using negative pressure, it is difficult to obtain finely divided bubbles, and stable bubbles cannot be obtained. Furthermore, it is necessary to attach the air blowing pipe 6 to the circulation pipe 3a for connecting the bathtub 1 and the appliance body (bath pot 9),
Difficult for construction.

Means for Solving Problems In the bubble generating device of the present invention for solving the above problems, a heat exchanger for heating bath water, a circulation pump for circulating the bath water, and the circulation Equipped with an air pump for generating bubbles in the circulation line after discharge of the pump, and a filter for further subdividing the air,
It is provided with a structure to be attached to the circulation line on the discharge side of the air pump.

Effect The present invention has the above-described structure, when the circulating water is jetted into the bathtub by the circulating pump, air is introduced into the circulating water by the air pump, and the air is subdivided by the filter, so that pleasant bubbles are generated. In addition to being able to obtain air bubbles, it is possible to generate bubbles with a circulation pump having a small capacity, because the circulating water jet speed is not required.

Embodiment One embodiment of the present invention will be described below with reference to the drawings. The same parts as those of the conventional example are designated by the same reference numerals, detailed description thereof will be omitted, and different parts will be mainly described.

In FIG. 2, an air pump 8 is provided with a circulation pipe 3a (also referred to as a circulation conduit) between the circulation pump 5 and the ejection port 3. Reference numeral 9 denotes a filter, which is attached to the circulation pipe line on the discharge side of the air pump 8.

The operation of the bubble generating device configured as described above will be described. The circulating water jetted from the circulation pump 5 passes through the jet outlet 3 and jets into the bathtub 1. At this time, the air generated by the air pump 8 flows into the circulating water, and further passes through the filter 9 to become finely divided bubbles, which are ejected into the bath. You can enjoy a comfortable bath because a jet flow and subdivided bubbles are generated in the bathtub.

EFFECTS OF THE INVENTION As described above, according to the present invention, an air pump for generating bubbles and a filter for subdividing the air are attached to the circulation pipe after discharge of the circulation pump, whereby low-efficiency circulation is achieved. You can use a pump and you can get more subdivided bubbles to enjoy a comfortable bath.
