Description

[Detailed description of the invention] [Industrial field of application and overview of the invention] The present invention is for cleaning the dust removal filter of a bathtub for bubble baths, which cleans the dust removal filter installed in the water circuit that connects the bathtub and the bathtub. The present invention relates to a device in which the dust removal filter can be washed while being loaded without being removed from the water circuit, thereby making it possible to easily wash the dust removal filter.

[Prior art and its problems] As this type of bubble bath bath pot, there is one shown in FIG. 6, for example.

The bathtub 2 is connected to bathtub pipes 30 and 31 protruding from the outer wall surface of the bathtub 1, thereby forming a circulation circuit between the bathtub 1 and the bathtub 2.

The circulation circuit is provided with a circulation pump P for forcibly circulating bath water between the bathtub 1 and the bath pot 2 when heating a bath, and a bathtub-side opening of the bathtub pipe 31 on the discharge side. An air pressure feeding circuit 41 drawn out from the air pump 4 and piped therein is connected near the air pump 4 . A dust removal filter 5 for purifying the bathing water is disposed in the flow path adjacent to the upstream side of the connection between the bathtub pipe 31 and the air pressure feeding circuit.

In this device, when the air pump 4 is driven during bathing, the air pump 4 sends air to the air pressure feeding circuit 4.
The compressed air sent into the bathtub 1 is ejected from the bathtub pipe portion of the bathtub 1, and a flow of water is generated in the circulation flow path between the bathtub 1 and the bath pot 2, attracted by the ejection of the compressed air. Dust such as hair and towel fibers contained in this water flow is removed by a dust removal filter 5 disposed within the circulation flow path, thereby purifying the bathing water.

However, the above conventional filter has a problem in that the dirty dust removal filter 5 cannot be easily cleaned.

This is because in the above-mentioned conventional type, when cleaning the dust removal filter 5, the dust removal filter 5 is
This is because it has to be removed from the mounting part.

That is, in the above-mentioned conventional device, when cleaning the dust removal filter 5 that is dirty with dust attached, the dust removal filter 5 is removed by disassembling the piping near the filter, etc., and the removed dust removal filter 5 is cleaned. After that, you have to set it back up again. Therefore, each of these operations is time-consuming and the cleaning operation of the dust removal filter 5 cannot be easily performed.

[Technical Problems] The present invention consists of connecting a bathtub 1 and a bathtub 2 with a set of bathtub pipes 30 and 31 to form a circulation flow path between them, and connecting the bathtub 1 and the bathtub pot 2 near the opening on the bathtub side of the circulation flow path. An air pressure feeding circuit 41 drawn from an air pump 4 is connected to the air pump 4, and a dust removal filter 5 is inserted into the flow path located on the opposite side of the bathtub side opening of the circulation flow path across the connection. In order to easily clean the dust removal filter 5, it is a technical problem to make it possible to clean the dust removal filter 5 while it is installed in the flow path.

[Technical Means] The technical means of the present invention for solving the above problem is as follows: The drainage flow path 7 is branched to the flow path on the opposite side of the air pressure feeding circuit connection part with the dust removal filter 5 in between. An on-off valve 71 is inserted into the flow path 7, and compressed air supplied from the air pump 4 is connected to the air pressure feeding circuit connection side flow path of the dust removal filter 5 from the dust removal filter 5 side to the drainage circuit 7. A switching means 8 is provided for switching between the direction toward the side and the direction opposite thereto.

[Effect] The above technical means works as follows.

When taking a bath in a bubble bath state, the direction of the compressed air ejected from the air pressure supply circuit 41 is directed toward the bathtub 1 (the direction opposite to the part where the dust removal filter 5 is disposed), as in the conventional system described above. Keep it aimed at
In this state, compressed air is injected. Then, the inside of the bathtub 1 becomes a bubble bath state as in the conventional bathtub described above, and the dust in the bath water is filtered out by the dust removal filter 5 as in the conventional bathtub described above. Adhere to one side of it.

Next, when cleaning the dust removal filter 5, the switching means 8 is activated so that the direction of the compressed air supplied from the air pump 4 into the bathing water circulation flow path is directed toward the dust removal filter 5 side. Switch the direction of compressed air. That is, the compressed air enters from one side of the dust removal filter 5 and flows in the direction of exiting to the dust adhering surface on the opposite side. At the same time, the on-off valve 71 in the drainage channel 7 branched to the upstream side of the dust removal filter 5 is opened.

When the compressed air supplied from the air pump 4 enters from one side of the dust removal filter 5 and passes through the dust adhesion side on the opposite side, the dust adhering to one side of the dust removal filter 5 is removed by the compressed air. The water flows from the vicinity of the dust removal filter to the side of the drainage channel 7 which is branched, and is discharged from the drainage channel 7 to the outside via the on-off valve 71 which is in the open state.

Thereby, the dust removal filter 5 can be cleaned without being removed from the inside of the flow path.

[effect] The present invention has the following unique effects.

Since the dust removal filter 5 can be cleaned with the dust removal filter 5 attached without removing it from the flow path, the dust removal filter 5 is more convenient than the previously mentioned conventional type in which the dust removal filter 5 had to be removed from the flow path and cleaned. Cleaning is easy.

[Example] Next, an example of the present invention described above will be described in detail with reference to the drawings.

1 to 3 show a first embodiment of the present invention.

In this device, the bathtub 1, the bath pot 2, the air pump 4, etc. are connected by piping in the same way as in the conventional device described above, but the tip of the air pressure feeding circuit 41 is

When energized, the on-off valve 71 opens. Further, when the excitation coil 49 for the switching valve 47 is not energized, the other switching valve 47 is connected to the bathtub 1 as shown by the solid line in FIG.
On the other hand, when the excitation coil 49 is energized, the second ejection port 46 is turned to the side facing the dust removal filter 5, as shown by the imaginary line in the figure. The state is switched to the No. 1 jet nozzle 45 side.

Now, in this embodiment, when the bathtub 1 is filled with hot water and the cleaning switch S is turned OFF and the air pump 4 is operated, the injection nozzle 42
Since the excitation coil 49 for the switching valve 47 installed inside is in a de-energized state, the switching valve 47 is switched to the second spout 46 side (the nozzle side facing the bathtub direction). , the second spout 46
Compressed air is blown out from the bathtub 1, and the inside of the bathtub 1 becomes a bubble bath state. In addition, in this state where the cleaning switch S is turned OFF, the excitation coil 79 for the on-off valve 71 inserted in the middle of the drainage channel 7 branched to the upstream side of the dust removal filter 5 is also in a non-conducting state. Therefore, the on-off valve 71 is maintained in a closed state.

When compressed air is jetted out from the second jet port 46 facing the bathtub 1 side and used as a bubble bath, the bathing water in the circulation channel is attracted by the jet of compressed air and passes through the dust removal filter. 5 part flows in the direction shown by the arrow in FIG. It adheres to the surface on the side where the drainage channel is installed.

Next, when the cleaning switch S is turned on to clean the dirty dust removal filter 5, the excitation coils 49 and 79 respectively corresponding to the switching valve 47 and the on-off valve 71 for the drainage channel 7 become conductive. The switching valve 47 is switched to the first spout 45 side facing the dust removal filter 5, and the on-off valve 71 for the drainage channel 7 is opened.

When the air pump 4 is driven in this state, the compressed air sent from the air pump 4 is
It is injected from the injection nozzle 42 in the direction of the dust removal filter 5, passes through the dust removal filter 5 from one side in the direction in which the dust D has adhered, releases the dust D from the dust removal filter 5, and removes the dirt containing the dust D. Water is drained to the outside from the on-off valve 71 for the drain flow path 7 which is in the open state.

Thereby, the dust removal filter 5 can be cleaned.

In the second embodiment shown in FIG. 4, a dust removal filter 5 is installed in the lower suction side bathtub pipe 30 of the bathtub pipes 30 and 31 connecting the bathtub 1 and the bath pot 2. The dust removal filter 5
