JPH0671118A - Device for removing bathtub dirt - Google Patents

Abstract

PURPOSE:To prevent the back flow of matters taken out through a dirt suction port into a bathtub by installing a check valve between the dirt suction port and a storage part for collected matters. CONSTITUTION:Suspended matters including dirt and hair floating on the water surface in a bathtub 1 are taken out through a dirt suction port 3 by a pump 2 and stored in a part for collected matters 4. In this system, a check valve 5 is installed between the dirt suction port 3 and the storage part for collected matters 4. The suspended matters, which are collected when the valve 5 is opened, are prevented from the back flow into the bathtub 1 by the valve 5 closed while a dirt removing device is stopped.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust removing device for a bathtub which is provided with a check valve to prevent backflow of suspended dust such as dust and hair into the bathtub.

[0002]

2. Description of the Related Art Conventionally, there has been known a bathtub descaling device which sucks up suspended matter such as debris, hair, and dust from a debris suction port located in a bathtub and stores it in a collection storage unit such as a filter. There is.

[0003]

In the prior art, when the descaling device is stopped, if the inhaled debris, hair, etc. have not reached the collection storage such as the filter, the descaling is performed. There was a problem of backflow from the suction port into the bathtub. The present invention has been made in view of the above problems, and an object of the present invention is to provide a dust removing device for a bathtub in which dust, hair, dust, etc. sucked from the dust removing suction port do not flow back into the bathtub. To provide.

[0004]

According to the present invention, suspended matter such as dirt, hair and dust floating on the water surface of a bathtub 1 is sucked by a pump 2 from a dirt removing and sucking port 3 to a collected material storage section 4. A bathtub dust removing device configured to store a check valve 5 is provided between the dust removing suction port 3 and the collected substance storage unit 4, and the above problem is solved by this configuration. .

[0005]

[Function] Since the check valve 5 is provided between the dust removing suction port 3 and the collected material storage unit 4, even if the dust removing device is stopped, the dust, hair, and dust sucked from the dust removing suction port 3 Etc. are not stopped by the check valve 5 and do not flow back into the bathtub 1.

[0006]

EXAMPLE As shown in FIG. 4, the dust removing suction port 3 is formed in an L-shape by a vertical pipe 3a and a horizontal pipe 3b.
It is located inside. A pump 2 is arranged outside the bathtub 1. The suction side of the pump 2 and the bathtub 2 are communicated with each other by a pump side pipe line 6 for suction. A collection storage unit 4 such as a filter is provided in the pump side pipe line 6. The end of the pump side pipe line 6 is connected to the side wall 7 of the bathtub 1. The end of the horizontal pipe 3b of the dust removing suction port 3 is fastened to the side wall 7 of the bathtub 1 by a nut 8 and connected to the pump side pipe line 6. The collecting tube 9 for removing dust is freely movable up and down, and is slidably attached to the vertical pipe 3a of the suction inlet 3. A check valve 5 is provided at the end of the pump side pipe line 6, and the check valve 5 is biased by a spring 10 so as to open the pump side pipe line 6. The opening and closing of the pump side pipe line 6 is performed by the wire 13 that connects the air suction port switching dial 12 and the check valve 5 provided on the flange 11 of the bathtub 1 as shown in FIGS. 4 and 5. That is, in order to close the check valve 5, the air suction port switching dial 12 is fully turned to the right so that the dial is fixed and the wire 13 is pulled, so that the pulley 14 of the bathtub 1 and the pulley 15 of the check valve 5 side are connected. The sliding shaft 16 is pushed through to the bathtub 1 side through the closing of the check valve 5. On the contrary, in order to open the check valve 5, the air suction port switching dial 12 is turned counterclockwise to open the dial, and the check valve 5 is returned by the spring 10 to the sliding shaft 16 to the side opposite to the bath 1. The check valve 5 is opened.

When the jet switch 17 is turned on,
The pump 2 sucks the water in the bathtub 1 from the suction port 18,
It is pressurized and jetted from the jet nozzle 19 provided in the bath 1.
At the time of jetting, air is sucked from the air suction port switching dial 12 and mixed with the pressurized water. Next, when the air suction switching dial 12 is switched from the air suction port side to the dust removal suction side, the inside of the collection cylinder 9 of the dust removal suction port 3 becomes a negative pressure, and the collection cylinder 9 floats up and the water surface of the bathtub 1 is raised. Inhale suspended matter such as dust, hair, and dust on top. In this case, by opening the check valve 5, the suspended matter can be collected from the dirt removal suction port 3 into the collected collection storage unit 4, and the purified hot water is returned to the bath 1. Then, by closing the check valve 5, even if the dust removing device is stopped, dust, hair, or hair present between the check valve 5 and the collected material storage unit 4,
Dust and the like will not flow back into the bathtub 1 from the dust removal suction port 3.

FIG. 6 shows another example of the check valve 5, which is shown in an open state ((a) in the figure) and a closed state ((b) in the figure).

[0009]

Industrial Applicability The present invention has the following features: dust floating on the water surface of a bathtub,
In a decontamination device for a bathtub, in which suspended matter such as hair and dust is sucked in by a pump and stored in the collection storage section by suction with a pump, a check is performed between the decontamination suction opening and the collection storage section. Since a valve is provided, by opening the check valve, it is possible not only to collect suspended solids from the suction port but also to collect it in the collected material storage section, and by closing the check valve, dust can be collected. Even if the removing device is stopped, the dirt, hair, dust and the like sucked in through the dirt removing / sucking port are prevented from flowing back into the bathtub by being stopped by the check valve.
