Description

[Detailed Description of the Invention] The present invention relates to a forced circulation bath device in which water in the bathtub is pumped to a heat exchanger of a heat source device, heated, and then returned to the bathtub.

Conventionally, the heat source unit of the above-mentioned bath equipment and the bathtub have been connected through an opening provided in the side wall of the bathtub, and therefore, during construction, it is necessary to create an opening in the bathtub, which is extremely troublesome, and the bathtub is integrated. In the case of the unit bath, there was a problem with the waterproofness of the floor on which the unit bath was installed, so the above construction was not possible.

The present invention solves these conventional problems and also makes it possible to utilize the remaining water in the bathtub with a simple configuration and operation. explain.

Reference numeral 1 denotes a heat source device, which has a built-in heat exchanger 2 that heats water passing through it, a gas burner 3 that heats the heat exchanger 2, and a pump 4 that forcibly sends bathtub water to the heat exchanger 2.

Further, inside the main body 12, a suction chamber 18 communicating with the suction port 14 is formed at the center, a discharge chamber 19 communicating with the discharge port 15 is formed around the suction chamber 18, and connection ports 20, 21 communicating with each chamber are formed on the top surface of the main body. It is provided. Reference numerals 22 and 23 are flexible suction pipes and discharge pipes connected to the connection ports 20 and 21 of the main body 12 in the bathroom A, respectively, and the ends of both pipes 22 and 23 have connectors 40 and 4.
1 and connect both connectors 40 and 41 to the bathtub 1.
It can be detachably connected to connectors 25 and 26 connected to the outgoing pipe and the incoming pipe of the heat source device 1, respectively, which are attached to the side wall 24 above 3. Reference numeral 27 denotes a control device for the heat source device 1 installed in the bathroom A, which allows the user to select between operating the pump 4 alone and operating the pump 4 and burning the gas burner 3. Reference numerals 28 and 29 designate metal fittings that connect the connecting fittings 25 and 26 of the unit bath side wall 24 and the connecting fittings 8 and 9 of the heat source device 1 through the outgoing pipe 30 and the returning pipe 31 near the inspection opening 32 provided in the outer wall 10. .

In order to connect the heat source device 1 and the bathroom A in the above configuration, first attach the connectors 25 and 26, the outgoing pipe 30, and the returning pipe 31 to the side wall 24 of the unit bath 11, and then open the inspection port 32 and connect them. The outgoing pipe 30 and the returning pipe 31 are connected to the connecting fittings 8 and 9 of the heat source device 1 by fittings 28 and 29. Next, the connection port 20,
The main body 1 has a suction pipe 22 and a discharge pipe 23 connected to the main body 21.
2 is placed inside the bathtub 13, and a suction pipe 22 and a discharge pipe 23 are installed.
The connectors 40 and 41 of the side wall 24 are connected to the connectors 25 and 2 of the side wall 24.
6, respectively.

Then, when the pump 4 is driven and the gas burner 3 is burned, the water in the bathtub 13 is transferred to the suction port 1 of the main body 12.
4 to the heat exchanger 2 via the suction pipe 22,
The water heated by the heat exchanger 2 is discharged into the bathtub 13 from the discharge port 15 of the main body 12 through the discharge pipe 23,
Thereafter, such forced circulation is continued to boil the water in the bathtub 13.

As explained above in the embodiments, the present invention has a bathtub 1
In a forced circulation bath device, the water in the bathtub 13 is sent to the heat exchanger 2 of the heat source device 1 by the pump 4, heated, and then returned to the bathtub 13.In the bathtub 13, there are a suction port and a suction port 90 with a filter attached thereto. A discharge port with a different direction is opened, a suction chamber communicating with the suction port is formed in the center, and a suction chamber communicating with the suction port is formed around the suction chamber, and each chamber has a connection port 20 with the heat source device 1, 21 is installed, and the outgoing pipe 30 and the returning pipe 31 of the heat source device 1 are arranged.
Connecting fittings 25 and 26 are provided on the bathroom side wall 24, and connecting fittings 40 and 41 are integrally connected to the flexible suction pipe 22 and discharge pipe 23 connected to the connection ports 20 and 21 of the main body 12, respectively. , the connectors 40 and 41 of the two pipes are connected to the connectors 25 and 26 of the side wall 24.
Since the bathtub 13 is detachably connected to the bathtub, there is no need to provide an opening in the side wall of the bathtub 13 as in the conventional case, and this type of forced circulation bath system can be used even in a unit bath with an integrated bathtub. Become. In addition, it has the advantage that construction is extremely easy, not only for unit baths with an integrated bathtub, but also for unit baths with a separate bathtub and ordinary bathrooms, since there is no need to provide an opening in the bathtub for connection. Further, according to the present invention, when it is desired to use the remaining water in the bathtub 13 for washing or the like, the connection fitting 41 of the discharge pipe 23 is removed from the connection fitting 26 of the side wall 24 as shown in FIG. If the connecting fitting 43 of the bathtub 13 is connected to the connecting fitting 26 and the pump 4 of the heat source device 1 is operated, and if the gas burner 3 is caused to burn if necessary, the water in the bathtub 13 will be transferred to the return pipe 31 and the connecting fitting 26. ,
The remaining water is sent to the place where it will be used via the hose 42. According to the present invention, the remaining water in the bathtub can be used with a simple structure and operation, and has great practical effects.

Moreover, the main body is placed inside the bathtub, and the hot water is discharged from the bottom, so the boiling temperature is uniform from top to bottom.
Also, since the discharge port is oriented 90 degrees from the suction port, there is no hot water shot cycle, making it more efficient, and the filter attached to the suction port can also remove dirt from the bathtub.
