Description

[Detailed Description of the Invention] [Object of the Invention] The present invention purifies waste products secreted from the ephrine and avocrine lines on the human body surface contained in the whirlpool of the bathtub during circulation after bathing. This relates to a bath water circulation filtration device.

Conventionally, hot water in a bathtub has a water quality due to the dissolution of fatty acid esters, saturated fatty acids, unsaturated fatty acids, proteins, and ammonia nitrogen, which are old waste products secreted from the ephrin and avocrine glands on the surface of the human body. As a result, the bathtub becomes slimy after being used for a long period of time or by many people, and the hot water itself comes to have a bad odor, making it impossible to enjoy a comfortable bathing time and making it impossible to avoid bathing after taking a bath. Due to the lack of cleanliness and unsanitary conditions, especially in hotels and inns, hot water in bathtubs must be frequently replaced in order to maintain and manage the water quality, and this work is extremely hard work. A large amount of water is required, and in recent years, it has been difficult to secure water resources, and effective use of water resources has been called for.Activated carbon and diatomaceous earth filter aids are being used as a means to remove old waste that is the cause of the deterioration of water quality. There are devices that simply pass hot water from above and below or from the left and right through the cartridge containing the filter material, but in such devices, the contact between the filter material and the hot water is insufficient. Therefore, it is not possible to completely remove old waste, and the flow path is inevitably long in terms of removal efficiency, which has the disadvantage that the device itself becomes large.

° Since the present invention is capable of creating a vortex flow in the flow of hot water passing through the filtration unit, it is possible to make the filtration unit more compact, and the contact path with the filter medium in the filtration cartridge can be made longer. At the same time, by uniform contact, it is possible to remove old wastes such as fatty acid esters, saturated fatty acids, unsaturated fatty acids, proteins, and ammonia nitrogen secreted from the ephrin and avocrine filaments on the surface of the human body contained in the vortex. Therefore, it is an object of the present invention to provide a bath water circulation filtration device that can always maintain clean hot water for a long period of time, thereby making effective use of water resources and providing a comfortable and clean bathing time.

[Structure of the Invention] In view of the above, the present invention provides an inflow pipe formed into a bottomed cylindrical shape in a circulation device that sucks and discharges fluid to the outside using a pump and a predetermined fluid path inside a case body. A filter medium, etc. is filled in a cartridge storage container, which is provided on the side wall of the bottom side of the cylinder at an eccentric position from the center of the cylinder axis, and a discharge pipe is installed on the side wall at an eccentric position from the center of the cylinder axis on the opening side. An object of the present invention is to provide a bath water circulation filtration device in which a filtration unit that accommodates a filtration cartridge and whose opening is covered with an outer cover is interposed in a fluid path, thereby solving the above-mentioned drawbacks.

- ■ In the present invention, the hot water with deteriorated water quality in the bathtub is sucked by a pump, and the sucked hot water is introduced into the cartridge housing container from the inflow pipe, thereby reducing the deviation of the axis center of the cartridge housing container. The hot water introduced from the inlet pipe provided at the center is formed into a whirlpool state, and in this state, it is made uniform with the filter medium filled in the filtration cartridge, and is brought into contact with the filter medium filled in the filter cartridge through a long path.
