Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a hot water circulation type heat exchanger 2 in the body of the bathtub 1 so as to freely exchange heat with the hot water in the bathtub 1, a recess 8 in the apron 7 of the bathtub 1, and a recess 8 in the apron 7. 8 contains a hot water adjustment handle 10, a shower handle 12, and a mixing faucet 3
The amount of heat exchanged by the heat exchanger 2 can be adjusted with the hot water adjustment handle 10, and a part of the hot water supplied to the heat exchanger 2 is supplied to the shower handle 12 via the mixing faucet 3.
This relates to a bathtub device that can be freely supplied with water.

Conventionally, when installing a shower in a bathroom, preliminary piping had to be installed at the stage of constructing the bathroom, and the shower etc. had to be installed after the entire bathroom was completed, which took time. Furthermore, even if one wanted to replace only the bathtub in the bathroom currently in use and also install a shower, the shower would have to be installed by tearing down the wall and plumbing, which would take a long time to install. Furthermore, if the mixer faucet, shower, or hot water adjustment handle was installed protruding from the wall, there was a risk of hitting one's head or body.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a bathtub device that can be quickly and easily repaired or newly installed, hot water can always be used, and is easy to use. It is something.

The present invention will be explained in detail below with reference to the accompanying drawings. A heat exchanger 2 is attached to the outer surface of the body of the bathtub 1. The heat exchanger 2 is connected to, for example, a hot water storage device (not shown) through a hot water supply pipe 4 and a recovery pipe 5 so that hot water at a temperature of 50° C. to approximately 100° C. can be freely circulated. This heat exchanger 2 enables heating and adjustment of the hot water in the bathtub 1. A water supply pipe 6 is also connected to the heat exchanger 2, and by flowing water from the water supply pipe 6 to the recovery pipe 5, the bathtub 1 can be heated.
The flow rate adjustment valve 18 of the water supply pipe 6 is controlled by a hot water adjustment handle 10 via a wire rod type operation pipe 19. A branch pipe 15 of the hot water supply pipe 4 on the back is connected to the mixing faucet 3, and a branch part of the water supply pipe 6 is connected to the water supply pipe 6 so that water can be mixed at an appropriate temperature and supplied to the shower handle 12. are doing. An apron 7 is attached to the front side of the bathtub 1, and a recess 8 is formed integrally with the apron 7. The recess 8 accommodates a hot water adjustment handle 10 for operating the flow rate adjustment valve 9 in conjunction with the hot water supply piping 4 through a wire rod type operating pipe 14, and a shower with a hose 11 connected to the mixing faucet 3 also stored in the recess 8. The handle 12 is stored in a locking tool 13 so as to be freely removable.

When it is desired to heat the hot water in the bathtub 1, a large amount of hot water can be supplied to the heat exchanger 2 and heated by turning the hot water adjustment handle 10 and operating the flow rate adjustment valve 9. Furthermore, when the user wants to take a shower, he or she can adjust the mixing faucet 3 as appropriate and use the shower handle 12 to do so. In this way, you can adjust the temperature of the hot water and take a shower as appropriate while staying in the bathroom. Note that the position where the recess 8 is provided is not limited to the front side of the bathtub 1, but may be on the left or right side.

In the above embodiment, the recess 8 is formed integrally with the apron 7, but as shown in FIG. It's also good.

In the present invention, since the heat exchanger, hot water adjustment handle, shower handle, etc. are attached to the bathtub as described above, the bathtub device is placed in an appropriate position in the bathroom, and the heat exchanger and the mixing faucet are connected to hot water. Construction is completed simply by connecting the supply piping, water supply piping, and recovery piping, making installation extremely quick and easy. In addition, the space and walls of the bathroom can be used effectively, and the shower handle, hot water adjustment handle, and mixer faucet are housed in a recess in the bathtub apron, so there is no need to worry about the lid slipping and accidentally getting stuck in place. It is safe and will not fall into the bathtub. Since the heat exchanger, mixing faucet, etc. are all stored within the bathtub installation surface, it is possible to install as large a bathtub as possible even in a small bathroom, and it also has the advantage of being compact and easy to transport. . The same is true when renovating a bathroom; existing walls, etc. must be destroyed,
It also has the advantage of being extremely easy and economical to install without the need for painting work. Furthermore, a hot water adjustment handle and a shower handle are attached to the outside surface of the bathtub, and the amount of heat exchanged by the heat exchanger can be adjusted with the hot water adjustment handle, so that a portion of the hot water supplied to the heat exchanger is routed through the mixing faucet. Since the water can be freely supplied to the shower handle, you can fully close the mixing faucet in the bathroom, open the hot water adjustment handle to heat up the hot water in the bathtub, and also open the mixing faucet to mix water with hot water at the appropriate temperature. It can be used in conjunction with a shower or as a stand-alone shower.
