Description

[Detailed description of the invention] [Industrial application field] This invention is mainly used in domestic baths to remove dirt such as dirt floating in the water, or especially when re-boiling bath water that has been used once. This invention relates to a bath water circulation filtration device using an electric pump for removing dirt such as limescale that settles on the bottom of a bathtub.

[Conventional technology]

Conventionally, when using a bath in an ordinary household, especially when it comes to baths that boil water using a bath pot connected to the bathtub, rather than discarding the boiled water for that day, it is better to use it the next day. Water is often reused (sometimes for several days), and this tendency is especially noticeable in households with elderly people, as re-boiled water is less irritating to the skin. It was hot. However, after taking a bath, the bath water is usually a little dirty due to human grime and limescale deposited on the bottom of the bathtub, or floating hair. At most, the water was used to remove dirt such as hair floating on the water surface and was then reused as is.

[Problem that the invention attempts to solve]

As mentioned above, if you re-float the bath water and reuse it while leaving human grime and limescale deposits on it,
Dirt such as grime that had previously settled at the bottom of the bathtub is stirred up and begins to float in the water (hot water), which does not look very clean, and bacteria can also breed, especially if the temperature of the water is low. Since this is not very hygienic, the appearance of a device that can easily remove such precipitates has been awaited.

[Means to solve the problem]

The present invention has been devised to solve the long-standing problems mentioned above, which include a pump driven by an electric motor, a filtration filter, and a reverse switching of the inlet and outlet. A pipe that reaches near the bottom of the bathtub is connected to either the inlet or outlet of the pump, and the remaining inlet or outlet has a float that expands and contracts to follow the vertical movement of the water surface. The problem is solved by a bath water circulation filtration device characterized in that it is configured by connecting nozzle-like tube bodies having a structure.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, 1 is a bath water circulation filtration device according to the present invention, which is a pump driven by an electric motor (not shown) driven by a sufficiently insulated commercial AC power source or a battery such as a primary battery or a secondary battery. P and filter F that removes dirt such as limescale.
A pipe 4 reaching near the bottom of the bathtub 3 is connected to either the suction port or the discharge port of the pump P, and a pipe 4 is connected to either the suction port or the discharge port of the pump P. A nozzle-shaped pipe body 7 having a telescopic structure (in this embodiment, a sliding structure with double pipes) that follows the vertical movement of the water surface 6 by means of a float 5 is connected to the suction port or the discharge port. It is.

Although the reversal switching mechanism is not shown,
In order to prevent the dirt in the filtration filter from flowing back, the filtration filter including the water flow path of the filtration filter is always placed in the water flow path on the suction port side in the reversal switching mechanism of the suction port and the discharge port. The pipe that reaches near the bottom of the bathtub and the nozzle-like tube body can be integrally formed to make the structure more compact, and the nozzle-like tube body can be rotated along its own tube axis to change the suction direction or discharge direction. For example, an ejector mechanism that naturally sucks air by the negative pressure generated in the flow path by the flowing water itself between the outlet of the pump and the reversing switching mechanism in order to supply ions into the water. An air entrainment mechanism can also be provided as required.

[Functions and effects of the invention]

As described in detail above, the bath water circulation filtration device according to the present invention is combined with a filtration filter and a reversal switching mechanism for the suction port and the discharge port, and either the suction port or the discharge port of the pump is located near the bottom of the bathtub. A nozzle-like tube body with an expandable structure that follows the vertical movement of the water surface is connected to the remaining inlet or outlet by means of a float, so that sediment such as limescale, hair, etc. The pipe or nozzle-like tube that reaches near the bottom of the bathtub can be used as an inlet depending on the inlet and outlet reversal switching mechanism, so that the water circulation direction can be changed as indicated by f1 or f2 in the figure. In addition to being able to remove any of them by changing
Particularly in home baths, the water level tends to rise and fall (the amount of water changes), but due to the action of the nozzle-shaped tube with the above-mentioned expandable structure, the inlet (or outlet) can always be located near the water surface. It has now become possible to provide a bath water circulation filtration device that operates reliably and has a simple structure but is extremely useful.
