By combining this automatic cleaning device with a bubble bath,
A bubble bath with a cleaning device can be constructed, and the heavy labor of manually cleaning the bathtub can be relieved.

[Problem to be solved by the invention]

However, in the conventional cleaning device, the cleaning liquid injected into the bathtub from the cleaning nozzle is discharged from the bathtub along with the cleaning water that is subsequently injected, so there is a waste of detergent usage.

In addition, the cleaning device requires a pump that pumps the cleaning liquid to the cleaning nozzle and a cleaning system pipe line that incorporates the pump, and if this is incorporated into a bubble bath, the pipe configuration becomes extremely complicated. A problem arises in that the work efficiency of connection construction deteriorates. Moreover, it is necessary to install a pump for supplying the cleaning liquid separately from the pump for circulating hot water in the bubble bath.
Not only is there a waste of equipment usage, but the equipment also becomes larger, and when an automatic cleaning device is installed in a bathroom, there are disadvantages in that the effective space in the bathroom is significantly reduced.

The present invention has been made in order to solve the above problems, and its purpose is to eliminate wastage of detergent used, simplify the pipe configuration to facilitate pipe connection construction, and reduce the amount of hot water used in bubble baths. By using a single pump as both the circulation pump and the cleaning liquid injection pump, we aim to make effective use of equipment and downsize the device, and install an automatic cleaning device without significantly reducing the effective space in the bathroom. The objective is to provide a bubble bath with a cleaning device that allows for.

[Means to solve the problem]

In order to achieve the above object, the present invention is configured as follows. That is, the bubble bath with a cleaning device of the first invention is provided with a foam jetting nozzle that jets a foam stream on the wall of the bathtub, and a cleaning nozzle that jets a cleaning liquid at a position facing the inner wall surface of the bathtub. A return pipe is connected to the bathtub, and this return pipe is equipped with a pump that sucks hot water in the bathtub, and the outgoing pipe connected to the discharge side of the pump blows out bubbles through the respective open/close control valves. The second invention of the bubble bath with cleaning device is characterized in that it is branched into a first pipe line leading to the nozzle and a second pipe line leading to the cleaning nozzle. A jet nozzle that selectively sprays both a foam stream and a cleaning liquid is installed in the section, and a return pipe is connected to the bathtub, and a pump that sucks the liquid in the bathtub is connected to the return pipe. On the discharge side, outgoing pipes leading to the jet nozzles are connected to each other to form a common circulation path for hot water and cleaning liquid, and the air introduction passage for a bubble bath that introduces air into the circulating hot water has a passage when operating a bubble bath. The device is characterized by being provided with an air on/off valve that opens to introduce air into the circulating hot water and closes the passage during cleaning operation to prevent air from being introduced into the circulating cleaning fluid.

[Effect]

In the first aspect of the invention, when the on-off control valve communicating with the first pipe line is closed and the on-off control valve communicating with the second pipe line is opened to start the pump, the cleaning liquid stored at the bottom of the bathtub is discharged from the return pipe. The water is supplied to the cleaning nozzle through the circulation pipe leading to the pipe No. 2, and is circulated and sprayed from the washing nozzle toward the inner wall surface of the bathtub. Thereafter, the circulating injection of cleaning water (water from tap water, etc.) is performed in the same manner, and the inner wall surface of the bathtub is cleaned.

After this bathtub cleaning is completed, the bathtub is filled with hot water and the first
When the on-off control valve on the pipe side is opened and the on-off control valve on the second pipe side is closed to start the pump, the hot water in the bathtub is guided from the return pipe through the pump to the foam jetting nozzle, and from this foam jetting nozzle. A bubble stream is circulated and sprayed into the bathtub, making it possible to take a bubble bath.

In the second invention, when the air on-off valve is closed and the pump is started, the cleaning liquid accumulated at the bottom of the bathtub, for example, is guided through the circulation pipe to the jet nozzle, and the cleaning liquid is circulated from the jet nozzle toward the inner wall surface of the bathtub. The water is sprayed and the bathtub is cleaned.

After the bathtub has been cleaned, the bathtub is filled with hot water, the air on-off valve is opened, and the pump is started.The hot water in the bathtub is guided through the same circulation pipe to the same jet nozzle. A bubble stream containing a mixture of hot water and air is ejected from the ejection nozzle into the bathtub, making it possible to take a bubble bath.

The figure shows the system configuration of a first embodiment of a bubble bath with a cleaning device according to the present invention.

In the figure, a drain pipe 2 is connected to the bottom of a bathtub 1, and this drain pipe 2 is provided with a drain valve 3 made of a solenoid valve or the like. Further, a foam jetting nozzle 4 is provided on the inner wall surface of the bathtub 1. A return pipe 1o connected to the bottom side of the bathtub 1 is connected to the suction side of the pump 12 via a water flow sensor 13 and a temperature sensor 14 that detects the temperature of the cleaning liquid flowing through the return pipe 10.

A detergent supply pipe 15 is connected to a conduit on the suction side of the pump 12, and the detergent supply pipe 15 is connected to a detergent tank 17 via a detergent on-off valve 16 such as a solenoid valve.

This detergent tank 17 contains liquid detergent. The discharge side of the pump 12 is connected via a pipe line 18 to the inlet side of a heat exchanger 20 that functions as a heat source, and the outlet side of the heat exchanger 20 is connected to the heat source outlet pipe 8.

From this heat source outlet pipe 8, on-off control valves 6a, 6 such as solenoid valves are connected.
It is branched into a first pipe line 5a and a second pipe line 5b via b, and the first pipe line 5a is connected to the foam jetting nozzle 4. An air introduction passage 7 is connected to the first conduit 5a at a position slightly upstream of the foam jetting nozzle 4.

The tip side of the second conduit 5b is connected to a cleaning nozzle 11 disposed in the M9 of the bathtub 1 with its injection hole facing into the bathtub. From the discharge port of the pump unit 2 to a pipe line 18, a heat exchanger 20, a heat source outlet pipe 8, first and second pipe lines 5a,
5b to the nozzle 4.11 constitutes an outgoing pipe, and the return pipe 10 passes through the pump 12 to the first pipe 5.
The path that passes through the outgoing pipe on the a side and reaches the foam jetting nozzle 4 constitutes a circulation pipe for the bubble bath, and the path that passes through the outgoing pipe on the side a and reaches the bubble jetting nozzle 4 constitutes a circulation pipe for the bubble bath, and also connects the return pipe 10 to the pump 12.
The cleaning nozzle 1 passes through the outgoing pipe on the second pipe line 5b side through
The path leading to No. 1 constitutes a cleaning fluid circulation pipe. One end side of a water supply pipe 22 is connected to the pipe line 18, and the other end side of the water supply pipe 22 is connected to a cleaning water supply source such as a tap water via a water supply on/off valve 21 consisting of a solenoid valve or the like.

The drain valve 3, the on-off control valves 6a, 6b, the detergent on-off valve 16, and the water supply on-off valve 21 (valve opening/closing), the operation of the pump 12, and the combustion control fit of the heat exchanger 2o. Combustion control of the burner ff1I) is performed by the control section 23. A remote control 24 is connected to this control unit 23,
This remote control 24 has a cleaning button 2 for commanding cleaning operation.
5 and a bubble operation button 26 for commanding bubble bath operation. The control unit 23 receives commands from the cleaning button 25 or foam operation button 26 and detection signals from the water flow sensor 13 and temperature sensor 14, and opens and closes the various valves, operates the pump, and controls the combustion of the heat exchanger 2°. and control the automatic cleaning of the bathtub and the operation of the bubble bath.

The present embodiment is constructed as described above, and its cleaning operation and bubble bath operation will be explained below based on the flowcharts shown in FIGS. 2 and 3.

First, the cleaning operation will be explained based on the flowchart shown in FIG. First, when the cleaning button 25 of the remote controller 24 is turned on, this on signal is applied to the control section 23, and the control signal from the control section 23 opens the drain valve 3, which fills the bathtub l with dirty hot water. Drain this when there is. Step 102 determines whether or not this hot water has been drained completely.
will be judged.

That is, after sending the open signal for the drain valve 3 in step 101, the control unit 23 uses, for example, an internal timer to determine whether the time T required for the hot water in the bathtub 1 to completely drain has elapsed. I will do it. The drain valve 3 is kept open until the time T has elapsed, and when the time T has elapsed, it is determined that the hot water in the bathtub 1 has been completely drained, and the drain valve 3 is closed in step 103. Then, in step 104, the detergent on-off valve 16 is opened, and at the same time, in step 105
Then, it is determined whether the predetermined 17 hours have elapsed. That is, after applying an open signal to the detergent on-off valve 16, the control unit 23 counts the time using an internal timer, keeps the detergent on-off valve 16 open until the time T1 has elapsed, and When the time has elapsed, a predetermined amount of detergent (e.g. 2
It is determined that 0 cc) has been supplied from the detergent tank 17 to the conduit 18 through the detergent supply pipe 15, and the detergent on/off valve 16 is closed in step 106.

Next, when the water supply on/off valve 21 is opened in step 107, cleaning water such as tap water enters the pipe 18 through the water supply pipe, and is further supplied to the bottom side of the bathtub along with the detergent through the return pipe 10. Then, in step 108, the on-off control valve 6b is opened. In step 109, it is determined whether a predetermined 12 hours have elapsed since the water supply on-off valve 21 was opened. That is, the water supply on-off valve 21 is kept open until the predetermined 12 hours have elapsed, and the water supply on-off valve 21 is closed when the predetermined 12 hours have elapsed. By supplying the washing water to the bathtub for these 12 hours, the washing liquid (mixture of water and detergent) necessary for smoothly operating the pump 12 is stored at the bottom of the bathtub. If the cleaning liquid is too small, when the bomber 2 is started, the air in the bathtub 1 will be sucked in through the return pipe 10, impairing the smooth operation of the pump. On the other hand, as in this embodiment, by opening the water supply on-off valve 21 for only 12 hours and supplying cleaning water, an amount of cleaning liquid that does not interfere with pump operation can be secured, allowing smooth operation of the pump. .

After the 12 hours have elapsed, the water supply on/off valve 21 is closed. Then, in step 111, the pump 12 is started. By starting the pump 12, the cleaning liquid accumulated at the bottom of the bathtub is sucked into the pump 12 through the return pipe 10, and the sucked cleaning liquid passes through the pipe line 18 from the discharge side of the pump 12 for heat exchange. The cleaning liquid enters the vessel 20, where the cleaning liquid is heated to a temperature suitable for exerting its chemical cleaning ability, in this example, 50 to 60''C, and this heated hot water cleaning liquid is opened and closed from the heat source outlet pipe 8. Control valve 6b
It enters the second pipe line 5b through the cleaning nozzle 11 and is sprayed into the bathtub.

Then, this squirted cleaning liquid passes through the side wall of the bathtub 1 and flows down to the bottom side, and the cleaning liquid that has flowed down to the bottom side is sucked into the pump 12 from the return pipe 10 again, and after passing through the heat exchanger 20 in the same way, the cleaning liquid flows down to the bottom side. The cleaning nozzle 1 passes through the pipe line 5b of 2.
1 is squirted into the bathtub.

In this way, the cleaning liquid is repeatedly sprayed in circulation via the cleaning liquid circulation pipe. During this circulating injection, temperature control of the cleaning liquid is performed from steps 112 to 115.

That is, the control unit 23 determines in step 112 whether or not the temperature of the cleaning liquid is below 13°C (for example, 60°C) based on the temperature detection signal obtained from the temperature sensor 14. Heat exchanger 20 in the following cases
In step 113, the cleaning liquid is heated by burning the gas burner. Then, in step 114, the temperature of the cleaning liquid is set to 78.
It is determined whether or not the temperature is above T3"C. If the temperature is below T3"C, the burner of the heat exchanger 20 continues to heat the burner, and when the temperature of the cleaning liquid becomes T:1"C or above, step 115 The burner combustion of the heat exchanger 20 is stopped.

In addition, in step 116, it is determined whether 14 hours have passed since the pump 12 was started. If Ta time has not elapsed, steps 112 to 115 are repeated to adjust the temperature of the cleaning liquid to be circulated and injected. When 14 hours have elapsed during zero time during which the temperature is maintained at 11° C., the pump 12 is stopped in step 117, and the water supply on/off valve 21 is opened in step 118. As a result, the cleaning water supplied from the water supply pipe 22 passes through the pipe line 18 and the return pipe 10 in this order and enters the bathtub 1 from the bottom side, while the water flows through the heat exchanger 20, the heat source outlet pipe 8, and the second pipe line. 5b and reaches the cleaning nozzle 11, which is sprayed onto the inner wall surface of the bathtub, so that the cleaning liquid adhering to the inner wall surface of the bathtub and the dirt components removed by this cleaning liquid are washed away to the bottom side of the bathtub l. It will be done. At this time, in step 119, it is determined whether a predetermined 15 hours have elapsed since the water supply on-off valve 21 was opened, and when T1 time has elapsed, step 119 is performed.
At 0, the water supply on/off valve 21 is closed. Next step 121
Then, the drain valve 3 is opened, and the water, detergent, and dirt components accumulated in the bathtub are discharged from the drain pipe 2. In step 122, a timer is used to determine whether a predetermined 16 hours have elapsed since the drain valve 3 was opened. When 16 hours have elapsed, it is determined that the water, detergent, and dirt components accumulated in the bathtub have been completely discharged, and the drain valve 3 is closed in step 123 to complete the bathtub cleaning operation.

Next, the operation of the bubble bath operation will be explained based on the flowchart shown in FIG. After the bathtub 1 is filled with hot water, when the bubble operation button 26 is turned on, this ON signal is applied to the control section 23, and the control signal from the control section 23 closes the on-off control valve 6b in step 201, and the operation continues. At step 202, the switching control valve 6a is opened. and step 20
3, the pump 12 is activated. Then, the hot water in the bathtub is sucked into the pump 12 through the return pipe 10, and the sucked hot water passes through the heat exchanger 20 from the discharge side of the pump, and further passes through the open/close control valve 6a from the heat source outlet pipe 8. The foam then enters the first conduit 5a and is guided to the foam jetting nozzle 4.

At this time, the air introduction passage 7 enters the hot water passing through the first pipe line 5a.
Air is introduced from the bathtub, and a mixed fluid of pumped water and air becomes a foam flow and is jetted from the foam jetting nozzle 4 into the bathtub, thereby providing a bubble bath.

In step 204, it is determined whether a predetermined time T1 has elapsed since the pump 12 was started.

Until the T1 time has elapsed, the pump 12 continues to operate, and as hot water circulates in the bubble bath circulation pipe, a stream of bubbles is continuously ejected from the bubble jet nozzle 4 into the bathtub, creating a bubble bath. maintain the state of When the pump operation has elapsed for time T7, it is determined that the bubble bath time has elapsed, and the control unit 23 stops the pump in step 205. Then, in step 206, the control valve 6a is closed, and the bubble bath operation is completed.

In this first embodiment, the pipe from the return pipe 10 to the heat source outlet pipe 8 via the pump 12 and the heat exchanger 20 serves both as a circulation pipe for the cleaning liquid and a circulation pipe for bubble bath water. ,
A bathtub cleaning system and a bubble bath system can be constructed with a simple pipe configuration.

Furthermore, since the pump 12 serves both as a pump for circulating and spraying the cleaning liquid and for circulating and spraying the bubble bath water, it is possible to improve the efficiency of equipment usage and to downsize the system device. Coupled with the simplification of the pipe configuration, a bubble bath with a bathtub cleaning device can be installed without significantly reducing the effective space within the bathroom.

Note that various modifications are possible in this first embodiment. For example, as shown in FIG. The passage 5b may be branched and the cleaning liquid may be sprayed from each cleaning nozzle 11 toward the inner wall surface of the bathtub.
As shown in the figure, M9 of the bathtub 1 is formed into a folded shape,
A cleaning nozzle 11 is attached to this lid 9, a second conduit 5b is connected to the base end side of M9, a passage 27 leading from this second conduit to the cleaning nozzle 11 is provided inside the lid 9, and a second conduit 5b is provided inside the lid 9. It is also possible to introduce the cleaning liquid from the conduit 5b to the cleaning nozzle 11 through the passage 27 and to spray the cleaning liquid in circulation.

FIG. 6 shows the system configuration of a second embodiment of the bubble bath with cleaning device according to the present invention. In this second embodiment, a pair of jet nozzles 31 are provided on opposite walls of the bathtub 1,
A pipe line 5 constituting a part of the outgoing pipe is branched from the heat source outlet pipe 8 and connected to each jet nozzle 31, and a heat exchanger 20, the heat source outlet pipe 8, and the pipe line 5 are connected from the return pipe 10 via the pump 12.
5 to the jet nozzle 31 is configured as a common circulation pipe for cleaning and bubble bath, and the air introduction passage 7
An air on-off valve 30 such as a solenoid valve is interposed in the air on-off valve 3o, and the air on-off valve 3o is opened and closed under the control of the control section 23.The other configuration is the same as that of the first embodiment. Components common to those in the first embodiment are given the same reference numerals.

The ejection nozzle 31 of this second embodiment serves both as the cleaning nozzle and the foam ejection nozzle of the first embodiment.

In addition, the air on-off valve 30 is closed during bathtub cleaning operation to prevent air from entering the circulating cleaning liquid, and during bubble bath operation, the air on-off valve 30 is opened to introduce air into the circulating hot water.
It plays the role of creating bubbles.

Next, the operations of the cleaning operation and bubble bath operation by the apparatus of this second embodiment will be briefly explained. FIG. 7 shows a flowchart of the bathtub cleaning operation of this second embodiment. In this flowchart, the same step numbers are assigned to the same operations as in the flowchart shown in FIG. 2 of the cleaning operation of the first embodiment. In this second embodiment, the jet nozzle 31 serves both as a cleaning nozzle that jets cleaning liquid and as a foam jet nozzle that jets a foam flow during the bubble bath operation, so that the first There is no need to operate the on-off control valves 6a, 6b to switch the flow paths as in the embodiment. Therefore, in the cleaning operation of the second embodiment, the operation of step 108 in the flowchart of the first embodiment is omitted. The other operations are the same as those of the first embodiment, and a redundant explanation thereof will be omitted.

In this second embodiment, the cleaning liquid sprayed into the bathtub from the spray nozzle 31 is sucked from the return pipe 10 by the pump 12.
The water is circulated and sprayed from the discharge side of the pump 12 through the heat exchanger 20, the heat source outlet pipe 8, and the pipe line 5 in this order from the jet nozzle 31 toward the inner wall surface of the bathtub.

When the cleaning liquid passes through the heat exchanger 20, it is controlled to the optimum temperature to exhibit chemical cleaning power.

A flowchart of the bubble bath operation is shown in FIG. In this flowchart as well, the same step numbers are assigned to the same operations as those shown in FIG. 3 of the first embodiment, and their repeated explanation will be omitted. In this second embodiment, when the foam operation button 26 is turned on, the air on-off valve 30 is first opened in step 301, and then in step 203.
The pump 12 is activated, and hot water is circulated in the same manner as in the first embodiment. During the circulation of hot water, air is taken in from the air introduction passage 7 by the ejector action, and a fluid mixture of hot water and air is created upstream of the jet nozzle 31, and the mixed fluid flows from the jet nozzle 31 into the bathtub as a foam stream. It squirts inside and you are ready to take a bubble bath. When the bubble bath bathing time has elapsed and the pump 12 is stopped in step 205, the air opening/closing valve 30 is subsequently closed in step 306, and the bubble bath operation is completed.

In this second embodiment, the cleaning liquid circulation line and the hot water circulation line for bubble bath operation are constructed by the same pipe line, so the pipe line configuration is further simplified, and the space in the bathroom can be effectively utilized. It is possible to configure a bubble bath with a washing machine without constricting the space. Furthermore, since one pump 12 can perform both the cleaning operation and the bubble bath operation, it is possible to make effective use of the equipment, and it is also possible to further downsize the system device.

Note that the present invention is not limited to the above embodiments,
For example, in each of the above embodiments, the heat exchanger 20 was configured with a gas combustion type heater, but this heating source can be configured with various heat sources such as an electric heater. .

Further, it is also possible to omit the heating source for the cleaning liquid and to inject cleaning liquid that is not heated. However, in this case, the chemical cleaning power of the cleaning liquid will be lower than in the case of this embodiment, and it is more preferable to provide a heat source to heat the cleaning liquid as in this embodiment.

〔Effect of the invention〕

In the first aspect of the present invention, at least the part of the circulation pipe of the bubble bath from the return pipe to the pump is also used as a pipe for circulating and spraying the cleaning liquid. Compared to a system in which circulation pipes for the cleaning liquid are provided separately and independently, the pipe structure is extremely simple, and the work efficiency of pipe construction can be greatly improved.

In addition, since the circulation pump for the bubble bath also serves as the pump for circulating and spraying the cleaning liquid, there is no need to provide a pump for spraying the cleaning liquid separately from the bubble spray pump for the bubble bath, and the equipment can be used more effectively. In addition, it is possible to construct a compact system that combines a bubble bath and a bathtub cleaning system, and the excellent bubble bath with the cleaning device of the present invention can be installed in a bathroom without any hindrance (installation) without significantly reducing the effective space available in the bathroom. It becomes possible to do so.

In addition, in the second invention, although the circulation pipe for the bubble bath and the cleaning liquid circulation pipe for cleaning the bathtub are configured by the same circulation pipe, the pipe structure is further simplified, and The workability of piping construction is further improved, and it becomes possible to construct a combined system of bathtub cleaning and bubble bath more compactly.
