Description

[Detailed description of the invention] This invention relates to a cleaning device for bath water, etc. In particular, it makes it easy to clean and replace the filter material, and the filter case lid can be easily removed during operation. This relates to a bath water purifying device that prevents the use of water. Note that the cleaning device devised in this way is suitable for cleaning the bath water in bathhouses installed in ordinary households, or in bathhouses installed in guesthouses, inns, hotels, etc. It can be used not only to clean hot water but also to purify cooling water for injection molding machines, die casting machines, etc.

Conventional bath water purifier filters had a lid screwed into the mouth of the filter case to seal it, but the lid could not be opened easily because negative pressure was applied inside the case. . Therefore, when it is necessary to clean the inside of the case or replace the filter material, the opening of the case cannot be freely opened and closed, causing inconvenience. Furthermore, cleaning the filter media
Since they cannot be replaced easily, there is a problem in that the bath water cannot be sufficiently purified, and as a result, large amounts of hot water are frequently flushed down the drain.

This invention aims to eliminate the above-mentioned conventional drawbacks.

This invention is based on a device in which a filter consisting of a cylindrical case with a wide mouth that accommodates a filter material and a lid that seals the mouth of the case is installed in the suction pipe of a sewage circulation pump. A check valve is provided, and a lid is brought into close contact with the mouth of the case via packing to create a negative pressure inside the case to ensure sealing of the case, and a siphon part is provided in the discharge pipe of the pump. The siphon is characterized in that an automatic air suction valve is provided in the conduit between the top of the siphon and the end of the discharge pipe.

This automatically removes the negative pressure inside the filter case when the device stops operating, making it easy to open and close the case lid, making it easy to clean and replace the filter media. be.

Note that reference numeral 45 is a rotation stopper screw, and 46 is a retaining groove in which the rotation stopper engages.

The bath water cleaning device of the present invention, which is constructed as described above, is used by installing it on the top of the bathtub or in the corner of the washing area. The ends of the suction pipe 2 and discharge pipe 5 are immersed in the water.

Next, the operation of the device of the present invention will be explained. Filter 3
After opening the case lid 12 and filling the cylindrical case 8 with sufficient priming water and closing the case with the lid, when the pump 1 is started, the bath water sucked through the suction pipe 2 is filtered by its action. It is introduced into the container 3. When this bath water passes through the filter material 17 of the filter, hair, solid dirt, fiber waste, etc. in the bath water are removed, and relatively small dirt particles and odor-producing particles are also removed by the activated carbon 16. After being removed, it is introduced into the pump 1. The bath water discharged from the pump is pressurized by the pump and passes through the siphon section 5 of the discharge pipe 5.
It is discharged into the bathtub from the tube end via a.
Since a bubble generator 7 is attached to the end of the discharge pipe 5, when the bath water discharged from the discharge pipe flows through the bench lily pipe 41, a pressure difference is generated before and after the narrowest part in the flow path. Therefore, external air is introduced into the bathwater flowing out from the bench lily pipe through the air intake pipe 42, and this air is mixed with the bathwater and becomes a large amount of bubbles that are ejected into the bathtub. Provides a good stimulating effect on the human body during bathing. Incidentally, if the inner tube 35 is rotated 90 degrees and the bath water is discharged into the bathtub from the hole 43, the ejection of air bubbles will stop.

Note that while the pump 1 is in operation, negative pressure is generated in the cylindrical case 8 of the filter due to the action of the pump, so the lid 12 of the case comes into close contact with the opening 9 of the case via the packing 13, sealing the case. is ensured. Due to the negative pressure effect, the lid 12 does not easily open during pump operation. By the way, while the pump is in operation or when the pump is stopped, the automatic air suction valve 6 incorporated in the discharge pipe 5 operates as follows. This point will be explained below with reference to FIGS. 3A and 3B. During operation of the pump, a portion of the bath water discharged from the pump flows from the discharge pipe 5 to the valve seat 22.
It is introduced into the lower passage 29, which lifts the float 23 as shown in FIG. 3B, and brings the sealing plate 26 on the upper surface of the float into close contact with the air hole 20 of the cap 21. Therefore, bath water will not leak out from this automatic air suction valve 6. On the other hand, when the pump operation is stopped, the float 2 is lifted as described above.
3 is because the bath water inside the valve seat 22 is sucked down.
It is pushed down into the position shown in Figure 3A. Further, since the float 23 is provided with ventilation holes 24 and 25, the bath water in the pipe between the siphon top of the discharge pipe 5 and the end of the discharge pipe flows down into the bathtub. Therefore, the water inside the suction pipe 2 and the discharge pipe 5 will not be pulled against each other, and the case lid 12 of the filter can be opened easily.

Since this invention has the above-described structure and operation, the filter is completely sealed while the pump is in operation, and no water leakage occurs.
On the other hand, when the pump is stopped, the case lid of the filter can be easily opened, and the filter material and the like can be easily cleaned and replaced. As a result, dirty bath water and the like can be sufficiently purified, so water-saving effects can be expected.
