Description

[Detailed explanation of the idea] [Industrial application field]

This idea uses a circulation pump to forcefully circulate the hot water in the bathtub, heating it to an appropriate temperature, and
This invention relates to a hot water circulation device for baths that filters and makes hot water clear.

[Conventional technology and its problems]

A hot water circulation system for a bath constantly controls hot water at an appropriate temperature and uses a filtration means to remove dirt, bacteria, etc. contained in the hot water. A hot water circulation system with this structure uses a circulation pump to suck in hot water from the opening inside the bathtub of the outgoing circulation pipe, removes dirt contained in the hot water using a filtration means built into the main body, and then returns it to the hot water. . However, bathtubs have gently curved corners on the bottom and sides. For this reason, it is necessary to install the hot water inlet member to which the circulation pipe on the suction side is connected at a position slightly higher than the bottom surface of the bathtub. For this reason,
There was a drawback that the hot water inlet member could not draw in hot water from the bottom of the bathtub. Hot water cannot eliminate all the dirt and sand that adheres to and invades the human body. Therefore, as the bathtub is used, dirt accumulates on the bottom of the bathtub. Baths where the hot water is changed every day will prevent sediment from accumulating at the bottom of the bathtub. This is because when hot water is drained, sediment can be drained away. However, a hot water circulation device that continuously filters hot water using a filtration means can be used continuously for several months without replacing the hot water every day. Since this device does not exchange hot water, sediment accumulates on the bottom as it is used. When dirt accumulates at the bottom of the bathtub, it is necessary to clean the bottom of the bathtub. In this case, it is necessary to stop the operation of the hot water circulation device, drain the hot water in the bathtub, then fill the bathtub with water again and start operating the hot water circulation device.
This operation not only takes a lot of effort, but also
Since the water is filled with cold water, it takes a long time to warm it up to a temperature suitable for bathing. Furthermore, the heater consumes a large amount of electricity to heat the cold water, which is not economical. This drawback can be overcome if the suction pipe on the suction side can draw in hot water from the bottom of the bathtub. Japanese Utility Model Application No. 52-163048 discloses a device that can change the position at which the suction pipe on the suction side is attached to the bathtub. In this device, the suction pipe is fixed directly to the bathtub using a suction cup. Therefore, by changing the suction position of the suction cup, the suction end can be brought closer to the bottom of the bathtub. However, with this mechanism, it is difficult to securely fix the suction pipe to the bathtub. This is because the attachment position of the suction pipe is specified by the suction position of the suction cup. That is, if the suction position of the suction cup is set to the optimal position, the suction end of the suction pipe is not necessarily arranged at the optimal position. The present invention was developed with the aim of solving this drawback, and the important purpose of this invention is to be able to securely fix the hot water inlet member to the bathtub, and to
To provide a hot water circulation device for a bath that can suck hot water from the bottom of bathtubs of various shapes.

[effect]

The hot water circulation device for baths of this invention has a unique configuration and achieves excellent features that cannot be achieved with conventional devices. That is, in the hot water circulation device of this invention, while the hot water inlet member 15 is securely fixed to the bathtub 9,
Hot water can be drawn from the bottom 10 of the bathtub. This is extremely important for the hot water circulation device of this invention. This is because hot water circulation devices that continuously filter hot water can be used continuously for several months or more without replacing the hot water every day. This type of device has the disadvantage that foreign matter such as earth and sand accumulates on the bottom unless warm water is sucked in from the bottom as much as possible to remove foreign matter that settles to the bottom. Traditional baths, where the hot water is replaced every day, can remove sediment that has settled to the bottom when the hot water is drained. The hot water circulation device of this invention has a hot water inlet member 1
With the fixture 4 of No. 5 fixed to the bathtub 9, the vertically adjustable tube 2 is expanded and contracted downward to bring the hot water suction end closest to the bottom of the bathtub 9. In particular, the device of this invention does not change the attachment position of the fixture 4 to the bathtub 9 to bring the hot water suction end closer to the bottom.
The fixture 4 is fixed to the bathtub 9, and the vertically adjustable tube 2 is extended so that the hot water suction end approaches the bottom.
The hot water inlet member that allows the hot water suction end to approach the bottom of the bathtub in this state can be attached to any bathtub regardless of the shape of the bathtub, and the suction end can be brought close to the bottom. Furthermore, the hot water circulation device of this invention, which can fix the hot water inlet member to the bathtub in this state, also realizes the feature that the hot water inlet member can be securely fixed to the bathtub. With conventional devices in which the suction pipe is directly fixed to the bathtub using a suction cup, it is difficult to securely fix the suction pipe to the bathtub and to adjust the position of the suction end. This is because the attachment position of the suction pipe is specified by the suction position of the suction cup. Depending on the shape of the bathtub, the suction end of the suction pipe may not be located at the optimal position when the suction cup is placed at the optimal position. On the other hand, in the hot water circulation device of this invention, the fixed position of the fixture 4 and the suction end of the suction pipe 1 can be adjusted separately. This is because the vertically movable tube 2 is extendable and retractable with respect to the fixture 4. Therefore, the fixture 4 is fixed at a position where it can be securely fixed to the bathtub 9, and the hot water suction end can approach the bottom regardless of the shape of the bathtub. It is extremely important for hot water circulation devices to securely fix the hot water inlet member to the bathtub. This is because if the hot water suction end moves, air will be sucked in, causing the circulation pump 5 to malfunction. Further, the hot water circulation device of this invention has a drawback that when the hot water circulation is stopped, the hot water becomes cloudy. If the hot water becomes cloudy, filter the hot water using a filtration means.
This is a unique phenomenon for devices that can be used for long periods without replacing hot water. This phenomenon occurs when hot water is no longer circulated through the filtering means 16.
The reason for this is that the microorganisms that live here are no longer supplied with oxygen and nutrients, and the hot water clarification effect stops. Once hot water becomes cloudy, it takes several hours or more for it to become clear even if the hot water is circulated.
During this time, you will have to take a bath in cloudy warm water. In order to avoid this situation, it is important for the hot water circulation device of this invention to securely fix the hot water inlet member to the bathtub. A securely fixed hot water inlet member does not inhale air. Furthermore, the hot water circulation device of this invention can be used by being attached to bathtubs of various shapes. Even if the shape of the bathtub changes, the hot water circulation device of this invention can reliably fix the hot water inlet member and allow the suction end to approach the bottom. This is because the fittings of the hot water inlet member can be fixed at optimal positions, and the vertically adjustable tube 2 can be extended and contracted to access the bottom surface 10 of the bathtub. In this way, the hot water circulation device of this invention can securely fix the hot water inlet member to any shape of bathtub, and also has the feature of being able to suck hot water from the part close to the bottom and keeping the hot water clear. do.
