Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath water cleaning device with a bath water cleaning function, which enables good cleaning of the inside of a filter device and a pipe.

[0002]

2. Description of the Related Art If a conventional bath water cleaning device continues to be used for several months, dirt will adhere not only to the filtering device but also to the inside of the pipe,
The flow rate will decrease and the purification performance will also decrease. Therefore,
A device has been developed which is equipped with a multi-way valve in the device to wash the filter medium.

[0003]

However, none of the devices was able to clean the pipe line connected to the bathtub, and the flow rate could not be completely restored. Therefore, in order to clean the pipeline, in the past, another special removable cleaning device was attached to the water inlet and the water outlet for cleaning, but in this case, mounting and dismounting is troublesome, Alternatively, there is an uneconomical drawback in that a large amount of detergent is added to the bath water, and the bath water already washed in the bath is soiled with the detergent.

[0004]

Therefore, as a result of intensive studies, the inventor of the present invention has found that the invention circulates hot water in a bath by a circulation pump provided with a filtration device and a heater. In a bath hot water purifying device for forcibly circulating a passage to purify and keep warm water, a multi-directional valve for multi-directional switching in a pipe in or near a bath, and an operating means for appropriately switching the multi-directional valve The multi-way valve is provided with a storage means and a control means such that the drainage pipe end is located outside the bathtub and the operating means is switched to the normal circulation mode, the pipe line cleaning mode, and the cleaning water drainage mode. By using the provided bath water cleaning device having a bath water cleaning function and the like, the inside of the filter medium and the pipe can be cleaned well, and the above problems are solved.

[0005]

According to the present invention, when the flow rate decreases due to the clogging of the filter medium and the pipeline, the multi-way valve provided in or near the bath is switched to the pipeline cleaning mode (closed loop) for a certain time. After circulating, the multi-way valve is switched so that the hot water in the bathtub is discharged to the outside of the bathtub (rinsing water drainage mode), and the inside of the device and the inside of the pipeline are rinsed. As a result, it is possible to restore the filter medium and the pipeline to the initial state without polluting the bath water and requiring a special cleaning device. In addition, in the type with a pipeline cleaning agent tank,
A conduit cleaning agent is added to the conduit to clean the conduit. After that, the multi-way valve is changed over as in the case where the above-mentioned cleaning agent is not used.

When the operating means 10 is turned on, the normal circulation mode M1 is preferentially selected. Further, each electromagnetic valve of the multi-directional valve V is provided so as to be openable / closable via the electromagnetic valve control means 15 according to each mode.

As shown in FIG. 1, a pipe line 5b connecting the multi-way valve V, which is the four-way valve, and a place where the check valve 7 of the circulation pipe 5 is provided to a place near the hot water heat retention purification device A is connected to the pipe line 5b. A cleaning agent tank 16 is provided, and a cleaning agent (for example, sodium hypochlorite, sodium percarbonate, etc.) is added from a chemical addition port 16a of the cleaning agent tank 16 in the cleaning mode M2. It is configured to be able to. The pipeline cleaning agent can be automatically added via the pipeline cleaning agent adding means 17 (open / close valve or the like). In this case, the pipeline cleaning agent in the pipeline cleaning agent tank 17 is gradually dissolved into the circulation pipe 5 when the pipeline cleaning agent adding means 17 is opened. As the pipe line cleaning agent, various cleaning agents are used depending on the type of pipe, and the cleaning time is several minutes to several tens of minutes, and the operation is completed. Further, as shown in FIG. 4, the pipeline cleaning agent tank 16 and the pipeline cleaning agent adding means 17 may not be provided.

The operation will be described below with reference to the flow chart of FIG. 3 and FIG. First, the operating means 10
When is turned on, the normal circulation mode M1 is selected (see S1), and the bath water passes from the bath to the prefilter 6 of 1 by the circulation pump 2 of the hot water heat retention purification device A, and the filtration device 3,
The multi-directional valve V, which is a four-way valve, passes through the heater 4. That is, the bath water passes from the inside of the multi-way valve V, which is a four-way valve, only in the first direction (Y direction, see FIG. 1) which is the hanging direction. As a result, the bath water is returned to the bathtub 1 again.
It is supplied through the jet nozzle 8 and the like (see S2). As described above, the normal flow is flowing in the Y direction, which is the first direction, in the multidirectional valve V in FIG. 1, and is jetted into the bathtub 1 from the jet nozzle 8 arranged at the end to clean the bathtub hot water. Do.

Next, it is judged by the operation means 10 whether or not the mode is changed (see S3), and the pipe line cleaning mode M is determined.
When 1 is selected, the pipe cleaning mode M2 is set (see S4), and the bath water passes only from the inside of the 4-way valve to the left side in the second direction (L direction, see FIG. 1). The supply of bath water to the bath 1 is lost. In such a case, the bath water circulates only in the pipeline (circulation pipe 5) (see S6). In this case, by switching the flow direction of the circulation pump 2, the bath water can wash the inside of the circulation pipe 5 in the forward direction or the reverse direction.

In the state of the pipeline cleaning mode M2, it is judged whether or not the pipeline cleaning agent in the pipeline cleaning agent tank 16 is added, if necessary, and if it is necessary to add it. It is supported (see S7), the pipe line cleaning agent adding means 17 is operated to add the pipe line cleaning agent into the circulation pipe 5 (see S8), and the cleaning pipe is used in the circulation pipe 5 and the hot water heat retention purification device A. Are washed.

When it is judged whether the cleaning is completed or not (see FIG. 3), the cleaning water drainage mode M3 is established (see S10), and the bath water is in the third direction from the inside of the 4-way valve. Only the right side (R direction) passes, and the sewage after cleaning passes through the multi-way valve V, which is a 4-way valve, and is discharged to the outside of the bathtub 1 through the drainage pipe 9 without polluting the bath water. The process is performed (see S11), and it is judged whether or not the washing water drainage is finished, and when it is finished (see S12). In the case of the wash water drainage mode M3, the hot water in the bathtub 1 is used to rinse the inside of the warm water heat retention purification device A and the pipes. In this way, the rinse cleaning is performed for several minutes, and when the pipe cleaning is completed, the multi-way valve V enters the normal circulation mode.
