[Problem that the idea aims to solve]

However, the bathwater filtration device described above had the following problems. In other words, the bath water filtration device has a filter and a heater that are separate and built into the case. Because of this, if it is enlarged and installed in the bathroom space, it will narrow the space and make it difficult for bathers. It gave me a feeling of being cramped.

[0005] Therefore, in order to make the filtration device more compact, we integrated the filtration device and heater. Therefore, a system was devised in which the bath water was directly heated while being filtered by a filter. Kaka In this structure, a heater is attached to the lower end of the filtration case, and Inside, there was a replaceable case that housed the filter material. However, the replacement case is made of synthetic resin material to reduce weight, and If you place the replacement case on top of the heater, the heat from the heater may damage the replacement case. there was.

[0006] In addition, in order to prevent damage to the replacement case, attach a support member on top of the heater. The case was protected by a support member, but the structure etc. of the support member installation The process became complicated and the workability became complicated. The present invention aims to provide a bath water filtration device that can solve the above problems. purpose.

[0007]

[Means to solve the problem]

This invention consists of a pump that circulates the bath water and a filter that purifies the bath water. The filtration device can be installed near the bathtub body, and the filtration device By connecting the pipe and the bath water discharge pipe, the bath water inside the bathtub body can be circulated. In the bath water filtration device, a heater for heating the bath water is installed at the bottom end of the filter tank. In addition to being installed, a filtration case with a filtration material is built into the same case, and , multiple supporting protrusions are provided in the middle of the inner peripheral surface of the case, and the filter case is attached to the protrusions. A bath characterized in that a filtration case is supported on the tank by engaging the middle part of the tank. The present invention provides a hot water filtration device.

[0008] In addition, in this invention, a vertical support protrusion is provided on the outer peripheral surface of the filter material case to guide the support protrusion. A shaped groove is provided, and a support receiving portion that engages with the support protrusion is provided in the middle of the groove. It is characterized by

[0009]

[Effect of the idea]

In this invention, the bath water in the bathtub is filtered through the bath water suction pipe by driving the pump. The bathwater is sucked into the bathtub and circulated from the same device into the bathtub via the bathwater discharge pipe. However, the filtration tank inside the device purifies the bath water, and the bath water spout When spouting bath water from the throat of the spout nozzle installed in the pipe, the ejector Depending on the result, the air is mixed in the air mixing section, and the air-mixed bath water is spouted out to fill the bathtub. Air bubbles can be generated within the body.

0010 Also, when installing a filtration case into the tank, the groove of the case can be used as a support protrusion. Attach them together and engage the support receiving part in the middle of the groove. Moreover, the filter case By fitting the groove into the support protrusion of the tank, the inner peripheral surface of the case and Make sure that the outer circumferential surface of the filtration case is in close contact with the outer surface of the filtration case to ensure that the bath water passes through the filtration case. Hot water can be filtered smoothly. Furthermore, the filter case can be hung inside the tank. It is possible to prevent the case from coming into contact with the heater placed below it. can.

[0011] Therefore, according to the present invention, the case and its lower part can be connected without providing a supporting member. By preventing contact with the heater placed in the I can.
