DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath apparatus, and more particularly to a cleaning apparatus provided with a cleaning device for a processing tank for cleaning hot water.

[0002]

2. Description of the Related Art Recently, a bath apparatus equipped with a purifying apparatus 3 as shown in FIG. 4 having a purifying apparatus 3 that keeps hot water 2 in a bathtub 1 constantly and at a suitable temperature and allows comfortable bathing 24 hours a day is developed and widely used. I came to do it.

The cleaning device 3 is provided with a cleaning tank 4 filled with a filter 5, an activated stone 6, an activated carbon 7 and the like, and a heater 8 for keeping warm. The hot water 2 in the bathtub 1 pumped from the suction pipe 10 is circulated as indicated by the solid line arrow,
Dirt such as dirt and hair floating in the cleaning tank 4 is filtered by a filter 5, activated by an activated stone 6, and organic matter is adsorbed by an activated carbon 7 to perform a cleaning treatment first. I do.

Thereafter, the purified water is kept at an appropriate temperature by the heater 8 and is jetted out again into the bathtub 1 from a jet nozzle 13 attached to the end of the drain pipe 12.

[0005] In addition, since the cleaning device 3 is not only kept clean at a proper temperature after cleaning by removing the dirt from the hot water but also performs a sterilization process, the ozone of oxygen in the air is discharged by the discharge between the high voltage electrodes. A high-pressure discharge type ozonizer 15 for performing gasification is provided in an air supply pipe 14 connected to the jet nozzle 13, and ejects ozonized air into the bathtub 1 together with purified hot water.

In the cleaning apparatus 3 configured as described above, as the processing proceeds, dirt adheres to the cleaning processing tank 4 and clogging occurs, so that the flow rate of hot water decreases and the cleaning processing capacity is reduced. And the jet nozzle 13
The jet flow spouted from the water makes the amount of hot water and intake air small, so that a comfortable bubble bath cannot be enjoyed and eventually no hot water flows.

Therefore, the water flow sensor 16 is provided in the hot water circulation path.
When the water flow sensor 16 detects that the flow rate of hot water has dropped below a certain amount, the processing materials such as the filter 5, the activated stone 6, and the activated carbon 7 filled in the cleaning tank 4 are replaced. The instructions are given automatically.

However, when the processing material is exchanged by detecting the flow rate of the hot water with the water flow sensor, for example, even when the outlet of the jet nozzle is temporarily blocked and the flow rate of the hot water decreases, the filler is clogged. It is determined that they have been performed, and the filler is unnecessarily replaced.

For this reason, when a so-called backwashing device is installed so as to constantly increase the processing capacity for cleaning, to jet a strong jet stream, and to periodically wash the processing material in order to extend the life of the processing material. There is also.

In this backwashing, a water supply pipe 17 is connected to a drain pipe 12 and a drain pipe 18 is connected to a suction pipe 10 as shown by a dotted line in FIG. The hot water is circulated from the water supply pipe 17 to the drain pipe 18 in a direction opposite to that in the case of the cleaning treatment.

[0011]

However, in the case of the conventional backwashing method, the washing effect is not so high because the washing water is merely made to flow back into the processing material. Not only the cleaning treatment in the chemical treatment tank, but also all functions such as heating by the heater for keeping heat and ejection of the jet stream from the jet nozzle are stopped.

[0012] For this reason, the temperature of the water drops during bathing as well as during non-bathing, and it becomes impossible to take a bath after backwashing without additional heating, so that you can take a comfortable bath at any time of your choice. The effect is reduced by half.

Further, if the interval between backwashing is increased in order to avoid the above-mentioned drawbacks, the stain on the processing material becomes severe, and the backwash cannot be easily washed off.

The present invention solves the above-mentioned disadvantages of the prior art, does not stop the function of the cleaning device as a whole, and can efficiently clean the processing material for cleaning hot water. An object of the present invention is to provide a simple cleaning device.

[0015]

According to the present invention, hot water in a bathtub is pumped up from a suction pipe by a circulation pump, cleaned in a cleaning tank filled with a filter medium, and heated to an appropriate temperature by a heater for keeping warm. A cleaning water supply pipe for supplying cleaning water to the cleaning tank and a cleaning water for draining the cleaning water in a bathtub hot water purifying apparatus having a circulation pipe for discharging the cleaning water from the hot water pipe into the bathtub. A drain pipe is connected, and a bypass pipe is provided in which a circulation pipe from the water suction pipe is branched into a pipe to a cleaning treatment tank and a pipe to a heater for keeping heat. And a valve for shutting off the connection from the cleaning tank to the warming heater when the valve is operated, and connecting the switching valve to a bypass pipe when cleaning the cleaning tank. By supplying washing water Cleaning treatment to supply water to the cleaning tank and discharge it from the drain pipe, and heat insulation treatment of pumping the water in the bathtub from the suction pipe, heating it to the appropriate temperature with the heater and then discharging it again from the drain pipe to the bathtub The bathtub hot water purifier is characterized in that
I was able to solve the problem. The present invention also provides a bath tub hot water cleaning apparatus characterized in that a means for cleaning the inside of the cleaning processing tank is provided in the cleaning processing tank, and cleaning is performed when the switching valve is switched. Could be solved.

[0016]

The present invention is constructed as described above, and the hot water circulation pipe and the washing water circulation pipe are independently provided for the cleaning tank, and the cleaning water is supplied to the cleaning tank. When the hot water is distributed, the hot water distribution pipe is automatically switched by switching the hot water distribution pipe switching valve so that the hot water flows by bypassing only in the cleaning processing tank. Heating the hot water with the heater
All functions other than the cleaning processing in the cleaning tank of the cleaning apparatus, such as jetting of a jet stream from the jet nozzle, can be operated.

For this reason, the cleaning treatment tank can be washed even during bathing, so that it can be frequently performed at appropriate intervals to keep the treatment material constantly clean. Further, ultrasonic cleaning and air stirring cleaning are used in combination with cleaning. Thereby, the cleaning effect can be further enhanced.

The washing water drain pipe is connected to the bottom of the chemical treatment tank 4.

Reference numeral 26 denotes a cleaning device such as an ultrasonic cleaning device or an air-agitated cleaning device which is disposed in the cleaning processing tank 4 so as to be embedded in the processing material.

Next, the operation of the cleaning apparatus constructed as described above will be described.

FIG. 2 is a diagram showing a hot water distribution state when bath water is being cleaned by the cleaning tank 4.
At this time, since the cleaning of the cleaning tank 4 is not performed, the water supply valve 23 of the cleaning water supply pipe 22 and the drain valve 25 of the cleaning water drain pipe 24 are closed.

When the water supply valve 23 and the drain valve 25 for cleaning are closed, the control of the control device (not shown) causes the valve of the hot water distribution line to be switched to the hot water distribution line switching valve 19 to the cleaning treatment tank 4 side. It is controlled so that it is opened and the hot water cutoff valve 21 is also opened.

When the circulating pump 9 is operated in this state, the hot water 2 in the bathtub 1 is pumped up from the water suction pipe 10 as shown by an arrow, and after being cleaned in the cleaning tank 4 for heating. It is heated to an appropriate temperature by the heater 8 and circulates so as to be jetted out again into the bathtub 1 as a jet stream from the jet nozzle 13 at the end of the drain pipe 12.

Next, the flow of the cleaning water and hot water when the cleaning material is washed by flowing the cleaning water into the cleaning treatment tank 4 is shown in FIG.
The water supply valve 24 of the cleaning water supply pipe 23 and the drain valve 25 of the cleaning water drainage pipe 24 are opened, and the cleaning water is washed from above while cleaning the processing material as indicated by the dotted arrow. It flows down and is drained.

Of course, there is no problem even if the flow direction of the washing water is reversed, and an appropriate amount of a detergent may be mixed into the washing water.

When cleaning, the cleaning tank 4
For example, an ultrasonic cleaning device as the cleaning device 26 disposed therein also operates to further enhance the cleaning effect.

In order to clean the cleaning tank 4 as described above, the water supply valve 23 and the drain valve 2 of the cleaning water flow passage are provided.
When the valve 5 is opened, the valve provided in the hot water flow passage is controlled by the control device to switch the hot water flow conduit switching valve 19 to the bypass pipe 2.
It is opened to the zero side and the hot water cutoff valve 21 is closed.

When the circulation pump 9 is operated in this state, the hot water in the bathtub 1 sucked up by the hot water pipe 10 is
As shown by the solid line arrow, the hot water flows through the hot water distribution line switching valve 19, passes through the bypass pipe 21, reaches the upstream of the warming heater 8 of the hot water pipe 12, and is kept warm by the warming heater 8. 1
A jet flow is jetted out again from the jet nozzle 13 at the end of the nozzle 2 into the bathtub 1 and bypasses only the cleaning tank 4 and passes through all other processing devices.

For this reason, even if the cleaning treatment tank 4 is washed while taking a bath, the processing function of the cleaning treatment tank 4 cannot be exhibited with respect to the circulating hot water, but heating, jet flow jetting, and the like are not possible. Although not shown, all other processing functions of the apparatus provided in the cleaning apparatus 3 such as ozone sterilization can be exhibited.

Further, when the cleaning water is circulated and the cleaning tank 4 is cleaned, a program is set up in advance through experiments or the like to perform control such that cleaning is performed at predetermined time intervals, A water flow sensor is provided in the pipe 12 to detect and control a change in water flow according to clogging of the processing material in the cleaning treatment tank 4.

In the above embodiment, a filter, an activated stone,

Of course, a cleaning apparatus in which a plurality of cleaning processing tanks each containing these processing materials in independent tanks is provided. Even in the case of a device, in order to provide a flow path for hot water that bypasses only in the cleaning treatment tank, a bypass pipe that connects the suction pipe and the drain pipe at an appropriate position via a switching valve is provided. Is easy.

[0035]

The present invention has the above-described structure and operation, and efficiently cleans the processing material in the cleaning tank by using the cleaning device at an appropriate time regardless of the presence or absence of a bather. The processing material is constantly kept clean, extending the life of the processing material which is never cheap.

In this way, since the processing material for cleaning is constantly kept clean, not only is the processing result for the hot water high and the hot water is kept constantly clean, but also the discharge amount of the hot water is clogged with the processing material. As a result, the pine surge effect due to the continuous strong jet flow is obtained.

Further, since the heating by the heat retaining heater is not stopped during the washing, the temperature of the hot water drops, so that additional heating is not required, and the function as a 24-hour bath where bathing at an appropriate temperature can be enjoyed at any time is not lost.
