Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a bathtub filtering device.

(B) Conventional Technology Conventionally, a bathtub for home use or business use is equipped with a filtering device, which removes dust and the like from the bathwater and purifies the bathwater to remove the bathwater. This bath water can be used for a long time without replacement.

In such a filtering device, for example, the main body of the filtering device is installed outside the bath, and the tip portions of the bath hot water suction pipe and the bath hot water discharge pipe that are in communication with the main body are provided in the bath.

Further, in the main body of the filtering device, a pump for circulating bath water is built in, and a filtering tank containing a filtering material is provided.

Then, by operating the pump, while circulating the bath water in the bathtub through the bath water suction pipe and the bath water discharge pipe,
The filtering material in the filtration tank is used to purify the bath water.

(C) Problems to be Solved by the Invention However, the above filtering device has the following secondary points.

That is, when sucking the bath water into the filtering device from the opening of the bath water absorption pipe in the bathtub, dust such as hair in the bath water is also sucked in, and the dust is clogged in the filtration tank to circulate the bath water. Would not flow smoothly, and the clogging of the filtration tank would impose its load on the pump, causing the pump to malfunction.

In addition, since the filtration device sucks the bath water directly through the bath water absorption pipe, dust in the bath water is remarkably attached to the bath water absorption pipe, and cleaning of the pipe is easy due to its narrow interior. Could not be done.

It is an object of the present invention to provide a bathtub filtration device that can solve the above problems.

(D) Means for Solving the Problems In the present invention, a filtration comprising a pump for circulating the bath water, a filtration tank for purifying the bath water, and a bath water suction pipe and a bath water discharge pipe connected to the filtration tank. In the device,
