TECHNICAL FIELD The present invention relates to a circulating warm bath apparatus.

[0002]

2. Description of the Related Art Conventionally, hot water is discharged from a bathtub, the discharged hot water is filtered by a filtration device, and the heated water is heated to a predetermined temperature by a heating device. In a circulating warm bath apparatus that returns water to the bathtub, natural stones and artificial materials (such as ceramics) are used as filtration materials in the filtration device to purify hot water. Had to be removed and cleaned or replaced on a regular basis, and these operations required considerable effort.

[0003] As a method of washing the filtration material in the filtration device, there is also a method of washing the filtration material by refluxing a reflux path of hot water in a direction opposite to that in a normal operation.
In addition to the method of simply reversing the reflux path of hot water to discharge dirt from the filter material to the outside, and in addition to this method, using a mechanical stirring blade for the filter material to discharge more dirt from the filter material This method has been embodied.

[0004] However, if the return flow of the hot water is simply reversed in the reverse direction to that during normal operation, the detergency applied to the filter material is almost the same as the water pressure that causes dirt to adhere to the filter material during normal operation. However, only a part of the dirt adhering to the surface of the filter material could be discharged, and the filter material could not be washed cleanly.

[0005] Further, in the system using a mechanical stirring blade or the like as the filtering material, the filtering material is forcibly stirred by the stirring blade, so that the cleaning power of the filtering material is higher than when no stirring blade is used. Since the method using the stirring blade is a mechanical stirring device, the filtration material comes into contact with the stirring blade, so that the filtration material is crushed. When the operation returns to the normal operation, the crushed filtration material refluxes. There is also a problem that the inside of the bathtub is dirty.

Further, the method using the stirring blade has problems that the stirring blade has a mechanical structure, so that the stirring blade may malfunction or require power for rotating the stirring blade.

[0007] Further, when washing the filtration material, the hot water reflux path is recirculated in the opposite direction to that during normal operation, so that two sets of three-way valve type flow dividers are provided to switch the reflux path. However, there is a problem that the size of the entire apparatus is inevitably increased.

In addition, a normal operation is performed immediately after the filtration material is washed. When the filtration material is washed, the dirt generated when the filtration material is washed by refluxing in the opposite direction to the normal operation operation. Since a part of the dirt remains in the course of the reflux, there is also a problem that the dirt is returned to the bathtub.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is possible to efficiently clean a filtering device and always keep clean hot water free from contamination in a bathtub. It is intended to provide a circulating warm bath apparatus which enables comfortable bathing.

[0010]

The gist of the present invention will be described with reference to the accompanying drawings.

[0011] A circulating hot bath apparatus for discharging hot water from a bathtub, filtering the discharged hot water with a filtration device, heating the hot water to a predetermined temperature with a superheater, and then returning the hot water to the bathtub, The present invention relates to a circulating warm bath apparatus characterized in that an air bubble generator for generating air bubbles is provided in the filtration device.

Further, in the circulating warm bath apparatus according to the first aspect of the present invention, an air bubble generating apparatus for generating air bubbles in the filtering device is configured to generate air bubbles in the bathtub. It is.

[0013] In the circulating warm bath apparatus according to the first aspect, when bubbles are generated in the filtration apparatus and the inside of the filtration apparatus is washed, the reflux path of the hot water is refluxed in a direction opposite to that in the normal operation, and the circulation path from the filtration apparatus. The present invention relates to a circulating warm bath apparatus characterized in that discharged hot water is drained.

Further, in the circulating warm bath apparatus according to any one of claims 1 to 3, the hot water discharged from the bathtub flows into the inflow port, and the hot water flowing from the inflow port flows out to the filtering device or the heating device. An outlet and an outlet, an outlet for flowing hot water flowing out of the heating device into the outlet and flowing out of the bath, and a drain for flowing hot water flowing out of the filtering device to the outlet and discharging the water to the outside; A circulating warm bath apparatus characterized in that a flow divider having a five-way valve structure comprising:

[0015]

Since the bubble generating device 4 for generating air bubbles is provided in the filter device 2, when the filter material in the filter device 2 is washed, the filter material is washed only with a hot water flow as in the conventional case. compared to the case of washing the filtered material with water which is mixed with air bubbles in warm water, for example, the pressure in the filtering device 2 is raised from about 0.2 kg / cm ² to about 0.3 kg / cm ^2,
The cleaning power (stirring power) is 1.5 times or more, and the cleaning power for cleaning the filtering material in the filtering device 2 is greatly improved.
Can be washed very efficiently.

Further, since the filtration material in the filtration device 2 is not washed by mechanical stirring contact as in the prior art, there is no problem that the filtration material is crushed, and the synergistic effect of the hot water flow and the air bubbles does not occur. The filtration material flies in the filtration device 2, and the dirt attached to the filtration material is easily peeled off, so that the efficiency of washing the filtration material can be greatly enhanced.

Therefore, by passing the dirty hot water discharged from the bathtub 1 through the filter device 2 which has been always cleaned, it is possible to always return clean, clean water to the bathtub 1 in a very simple manner. A circulating warm bath apparatus that enables always comfortable bathing can be provided.

Further, since air bubbles are generated in the bathtub 1 by the air bubble generating device 4 for generating air bubbles in the filtering device 2, air bubbles are generated in the bathtub 1 during bathing. The bubble allows comfortable bathing, and the movement of warm water in the bathtub 1 becomes active, so that dirt attached to the bathtub 1 or the wall of the bathtub 1 becomes easier to remove,
Since this dirt is discharged from the bathtub 1, the bathtub 1 and the hot water in the bathtub 1 can always keep a clean state,
You can always take a comfortable bath.

Since one bubble generating device 4 is also used for cleaning the filtering device 2 and supplying bubbles to the bath 1, the air bubbles are introduced into the bath 1 and the device for cleaning the filtering device 2 as in the prior art. Compared with a case where a device for supplying is separately provided, the configuration of the entire circulating warm bath apparatus can be simplified, the size of the entire apparatus can be reduced, and the manufacturing cost of the apparatus can be reduced.

When cleaning the inside of the filtration device 2 by generating air bubbles in the filtration device 2, the hot water return path is refluxed in a direction opposite to that in the normal operation, and the hot water discharged from the filtration device 2 is drained. With such a configuration, the hot water contaminated by washing the inside of the filtration device 2 can be reliably drained without being returned to the bathtub 1.

Since the flow distributor 5 having a five-way valve structure is provided, the hot water discharged from the bathtub 1 flows into the inlet 6, and the hot water flowing from the inlet 6 flows out of the outlet 7 to the filtration device 2. Alternatively, the hot water flowing from the inlet 6 flows out of the outlet 8 to the heating device 3, the hot water flowing out of the heating device 3 flows into the outlet 8, and the hot water flowing from the outlet 8 flows out of the outlet 9. The hot water flowing out of the bathtub 1 and the hot water flowing out of the filtering device 2 can flow into the outlet 7, and the hot water flowing into the outlet 7 can be drained out of the device through the drain port 10. By using the flow divider 5 having a valve structure, the return path of the hot water can be switched very easily between the return path in the normal operation and the return path in the opposite direction to the normal operation. So as to form a return path during normal operation The flow path is switched by using two sets of three-way valve type flow dividers, i.e., a three-way valve type flow divider and a three-way valve type flow divider for refluxing in the opposite direction to that during normal operation. The configuration of the entire apparatus can be significantly reduced in size as compared with the case of the configuration shown in FIG.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A circulating warm bath apparatus according to one embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, as shown in FIG.
The hot water discharged from the outlet 19 is discharged by the pump device 12 so as to flow into the circulation pipe 11 by a predetermined amount, and the discharged hot water flows into the inlet 6 of the five-way valve type flow divider 5,
The hot water that has flowed into the inflow port 6 flows out of the outflow port 7, flows into the filtration device 2, filters the hot water contaminated by the filtration material provided in the filtration device 2, and sends clean water to the heating device 3. After the hot water is heated to a predetermined temperature by the heating device 3, the hot water flowing out of the heating device 3 flows into the outlet 8 of the five-way valve type flow divider 5, and the hot water flowing into the outlet 8 flows out of the outlet 9. The hot water flows out of the bathtub 1 through the outlet 20 of the bathtub 1.

In the above-described configuration, the hot water return path is a return path during normal operation, and when the filter material in the filtration device 2 is contaminated or when the filter material is washed, the hot water return path is used. The flow divider 5 of the five-way valve type is adjusted so that the path is in the opposite direction to that during the normal operation, and the outlet 19 of the bathtub 1 is adjusted.
The hot water discharged from the inflow into the inflow port 6 of the flow divider 5, the hot water flowing into the inflow port 6 is discharged from the outflow port 8 and flows into the heating device 3, and the hot water flowing out from the heating device 3 is filtered into the filtration device 2. Then, the filter material provided in the filter device 2 is washed with the warm water flowing into the filter device 2, and the hot water contaminated by washing the filter material flows into the outlet 7 of the flow divider 5. The dirty hot water flowing into 7 is drained from the drain port 10 of the flow divider 5 to the outside of the circulating hot bath apparatus.

The hot water flowing into the filtration device 2 is
When cleaning the filtration material provided in the filter device 2, a bubble generator 4 for generating bubbles is provided in the filter device 2,
The filter material provided therein can be efficiently washed with warm water mixed with air bubbles.

The bubble generator 4 provided so as to generate air bubbles in the filter device 2 can generate air bubbles in the bath tub 1 from the air bubble jet mat 13 disposed in the bath tub 1 through the air bubble jet valve 14. With the configuration as described above, the case where the bubbles generated from the bubble generator 4 are generated in the filtering device 2, the case where the bubbles are mixed into the warm water flowing out from the outlet 9 of the flow divider 5 and flows into the bathtub 1. Bubble switching valve to switch to
15 is provided, and a constricted portion 18 (Venturi portion) is provided in the circulation pipe 11 between the outlet 9 of the flow divider 5 and the bathtub 1 so that bubbles generated from the bubble generating device 4 can be bubbled by the bubble switching valve 15 and the ozone device 16. It is configured to be mixed with the warm water in the circulation pipe 11 provided with the constricted portion 18 through the hole.

When the bubbles generated from the bubble generator 4 are supplied into the filtration device 2, the bubbles discharged from the bubble switching valve 15 are supplied to the filtration device 2 via the check valve 17. It is composed.

Since the bubbles mixed from the constricted portion 18 of the circulation pipe 11 are bubbles that are ozonized by the ozone device 16, the hot water that flows into the bathtub 1 contains the ozonized bubbles. The hot water mixed with the ozonized air bubbles can activate the movement of the hot water in the bathtub 1 while the bathtub 1 can be comfortably bathed.
The dirt and the like adhering to the inside and to the bathtub 1 wall can be easily removed, and the dirt is discharged from the bathtub 1. Therefore, the bathtub 1 and the hot water in the bathtub 1 can always keep a clean state. A comfortable bath can always be taken with warm water mixed with ozonized air bubbles.

The flow path of the hot water is recirculated in the direction opposite to the normal operation to generate air bubbles in the filtration device 2, and
After washing the inside, in order to make the reflux path of the hot water more clear, the hot water flowing out of the outlet 19 of the bathtub 1 was flowed into the inlet 6 of the flow divider 5 and flowed into the inlet 6 as rinsing cleaning. The hot water flows out of the outlet 7 and flows into the filtering device 2, the hot water flowing out of the filtering device 2 flows into the heating device 3, and the hot water flowing out of the heating device 3 flows into the outlet 8 of the flow divider 5, Since the hot water that has flowed into the outlet 8 is configured to be drained out of the apparatus through the drain port 10, the rinsing and washing can make the progress of the reflux of the hot water more clear. Does not return to the bathtub 1 by the adjustment, and the entire circulating temperature bath apparatus can be washed very cleanly. After the rinsing and washing is completed, the hot water return path is set as the return path for normal operation, and the bathtub 1 is returned. I feel ozonized inside It is possible to always take a comfortable bath by flowing warm water mixed with foam.

As described above, according to the present invention, since the bubble generating device 4 for generating air bubbles is provided in the filtering device 2, when the filtering material in the filtering device 2 is washed, only the hot water flow is required. When the filtration material is washed with a stream of hot water mixed with air bubbles as compared to the case where the filtration material is washed with, for example, the pressure in the filtration device 2 is about 0.2 kg / cm ² to 0.3 kg / c.
m ² , the cleaning power (stirring power) becomes 1.5 times or more, the cleaning power for cleaning the filter material in the filtration device 2 is greatly improved, and the filtration device 2 can be cleaned very efficiently. .

Further, since the filtration material in the filtration device 2 is not washed by mechanical stirring contact as in the prior art, there is no problem that the filtration material is broken, and the synergistic effect of the hot water flow and the air bubbles does not occur. The filtration material flies in the filtration device 2, and the dirt attached to the filtration material is easily peeled off, so that the efficiency of washing the filtration material can be greatly enhanced.

Therefore, by passing the dirty hot water discharged from the bathtub 1 through the filter device 2 which has been always cleaned, it is possible to always return clean clean hot water to the bathtub 1 by a very simple method. A circulating warm bath apparatus that enables always comfortable bathing can be provided.

Further, since the air bubbles are generated in the bathtub 1 by the air bubble generating device 4 for generating air bubbles in the filtering device 2, the air bubbles are generated in the bathtub 1 during bathing. The bubble allows comfortable bathing, and the movement of warm water in the bathtub 1 becomes active, so that dirt attached to the bathtub 1 or the wall of the bathtub 1 becomes easier to remove,
Since this dirt is discharged from the bathtub 1, the bathtub 1 and the hot water in the bathtub 1 can always keep a clean state,
You can always take a comfortable bath.

Since one bubble generating device 4 is also used for cleaning the filtering device 2 and supplying air bubbles to the bath 1, the air bubbles are introduced into the bath 1 and the device for cleaning the filtering device 2 as in the prior art. Compared with a case where a device for supplying is separately provided, the configuration of the entire circulating warm bath apparatus can be simplified, the size of the entire apparatus can be reduced, and the manufacturing cost of the apparatus can be reduced.

When cleaning the inside of the filtration device 2 by generating air bubbles in the filtration device 2, the hot water return path is refluxed in a direction opposite to that in the normal operation, and the hot water discharged from the filtration device 2 is drained. With such a configuration, the hot water contaminated by washing the inside of the filtration device 2 can be reliably drained without being returned to the bathtub 1.

Since the flow distributor 5 having a five-way valve structure is provided, the hot water discharged from the bathtub 1 flows into the inlet 6, and the hot water flowing from the inlet 6 flows out from the outlet 7 to the filtering device 2. Alternatively, the hot water flowing from the inlet 6 flows out of the outlet 8 to the heating device 3, the hot water flowing out of the heating device 3 flows into the outlet 8, and the hot water flowing from the outlet 8 flows out of the outlet 9. The hot water flowing out of the bathtub 1 and the hot water flowing out of the filtering device 2 can flow into the outlet 7, and the hot water flowing into the outlet 7 can be drained out of the device through the drain port 10. By using the flow divider 5 having a valve structure, the return path of the hot water can be switched very easily between the return path in the normal operation and the return path in the opposite direction to the normal operation. So as to form a return path during normal operation The flow path is switched by using two sets of three-way valve type flow dividers, i.e., a three-way valve type flow divider and a three-way valve type flow divider for refluxing in the opposite direction to that during normal operation. The configuration of the entire apparatus can be significantly reduced in size as compared with the case where the configuration is adopted.
