[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath device, and particularly to a bath water cleaning device for performing cleaning treatment such as filtration, heat retention and sterilization while forcibly circulating hot water in a bath. The present invention relates to a device that allows a person to temporarily cut off the power supply to the heater as needed at any time.

[0002]

2. Description of the Related Art Recently, a bath water purifying device has been actively used, which keeps the hot water in the bathtub clean and at an appropriate temperature constantly, allows a comfortable bathing at any time for 24 hours, and saves water.

An example of such a bathtub cleaning device is as shown in FIG. 6, in which 1 is a bathtub, 2 is hot water, 3 is a suction pipe for pumping up hot water 2 in the bathtub, and 4 are An apparatus main body in which devices for cleaning the hot water pumped up by the hot water suction pipe 3 are collectively arranged, and 9 is a spout pipe for ejecting the hot water treated by the device main body 4 again into the bathtub 1. .

In order to remove dirt from the bath water, the apparatus body 4 is filled with various granular filter media such as activated carbon, activated stone, porous ceramic balls, etc., or a fibrous filter, individually or in combination, and a filtration tank 5. A circulation pump 6 for forcedly circulating hot water, a heater 7 for keeping the hot water at an appropriate temperature, an ozonizer 8 for sterilizing the hot water with ozone, and other cleaning processing equipment are provided.

Numeral 10 is a prefilter attached to the tip of the hot water pipe 3 for removing large dirt in advance before it is pumped up to the apparatus main body 4, and 11 is hot water after cleaning treatment in the bathtub 1 as a jet flow having a high flow rate. Intake pipe 1 ejected to the
Reference numeral 2 is a jet nozzle connected to the ejector section.

A solenoid valve 13 for opening and closing the pipe line is provided at the tip of the intake pipe 12 connected to the ejector portion of the jet nozzle 11, and an ozonizer 8 is provided on the way, and when the solenoid valve 13 is opened, the jet nozzle 11 is opened. The air is sucked from the intake pipe 12 by the intake force of the air, and this air is mixed in the hot water at the ejector portion 24, and the hot water is jetted from the jet nozzle 11 into the bathtub 1 together with the hot water to form a bubble bath. The generated air is ozoned and jetted into the bath 1 to sterilize the hot water 2 with ozone.

Further, in this apparatus, in order to remove dirt from the filter material of the filtration tank 5, the hot water is back-flowed into the tank for so-called back-washing, or in order to strengthen the jet flow, the hot water is passed through a bypass pipe having a low resistance. Switching valves 14 and 15 are provided on the hot water pipe 3 and the hot water pipe 9, respectively, so that the pipe lines can be switched.

Reference numeral 16 designates a hot water suction pipe 3 and a hot melt pipe 9 for forming a bypass pipe line which does not pass hot water in the filtration tank 5 having a large resistance.
Reference numeral 17 denotes a bypass pipe connected to the hot water suction pipe 3 via the switching valve 14 for discharging hot water for backwashing.

Reference numeral 18 is a check valve provided in the hot water suction pipe 3 for preventing hot water in the pipe line from leaking out when it is filled with water or flowing back into the bathtub 1 when the operation of the circulation pump is stopped. No. 19 shows that the hot water in the bathtub is drained, or air is sucked into the pipeline due to equipment damage or other reasons, and the circulation pump loses its hot water absorption capacity, and the hot water flows into the circulation path. To prevent the pump itself from being broken or the heater 7 from becoming an empty state, and to prevent the pressure difference between the suction side and the discharge side of the circulation pump 6 as a water shortage sensor that acts as a safety device. Is a differential pressure sensor based on 20
Is a hot water temperature sensor for controlling the power supply to the heater 7 and constantly detecting the hot water temperature and sending it to the control device in order to keep the hot water temperature at an appropriate temperature.

In the device constructed as described above, the user can set various operation modes to operate as necessary, and normally, the operation is performed in the cleaning mode.
The hot water 2 in the bath tub 1 is filtered by a filtration tank 5 after removing a large amount of dirt with a pre-filter 10 and heated by a heater 7 and then ozoned air is jetted from a jet nozzle 11 at the tip of a jet pipe 9 for ozone sterilization. To do.

As described above, when the apparatus is operated in the cleaning mode, the ozonized air is constantly ejected into the bathtub 1, so that the bather inhales the ozonized air when taking a bath. Therefore, the bathing mode for cutting off ozone sterilization can be set only during the bathing time. When the bathing mode is set, the solenoid valve 13 is closed and the operation of the ozonizer 8 is stopped at the same time. The jetting of ozonized air into the bathtub is stopped during the bathing mode, which is set to about the time.

In addition, a jet mode is set so that a bath flow can be enjoyed by a bather by jetting a jet flow containing hot air into the bathtub, and the jet mode is further set in the bath mode. Then, only the solenoid valve 13 is opened and the air sucked from the intake pipe 12 is jetted from the jet nozzle 11 together with the hot water into the bathtub 1 to form a bubble bath. When the jet mode is set to be particularly strong, the switching valve 14 and 15 is switched so that the hot water 2 in the bathtub 1 pumped up from the hot water suction pipe 3 does not flow through the filtration tank 5 and the heater 7, but directly flows into the hot water pipe 9 through the bypass pipe 16.

Then, the resistance of the circulation path of the hot water is reduced and the flow velocity of the hot water flowing through the jet nozzle 11 is increased. At the same time, the degree of the negative pressure formed in the ejector section 24 is increased and the intake amount from the intake pipe 12 is increased. Therefore, the strength of the jet flow becomes stronger.

When it is desired to continue the cleaning process to wash the filter material of the filtration tank 5, the switching valves 14 and 15 are switched to filter the hot water 2 in the bathtub 1 pumped from the hot water suction pipe 3 through the bypass pipe 16. The inside of the tank 5 is made to flow backward, and the hot water discharge pipe 17
There is also provided a backwash mode in which a so-called backwash is performed so that the ozone is discharged from the tank, and a silent mode in which the amount of ozone suction is reduced at midnight to reduce the device noise.

[0015]

However, since the device configured as described above consumes a large amount of power, it is inconvenient to use other electric devices at home because the device is installed in the bathroom. Occurred.

That is, in recent homes, various electric appliances with large power consumption such as a hair dryer of about 1200 W, a microwave oven, an air conditioner, a clothes dryer, and a hot plate have already been used, and a heater of about 800 W is used here. If the bath water purifier that has a large power consumption of 900W and is continuously used for 24 hours is installed, the total power consumption in the home when using the electric appliances as described above is 30A, which is the contracted power for ordinary households
Ampere breakers on the distribution board will often fall over.

The problem that the ampere breaker that is affected by the total power consumption in the home is dropped can be solved by increasing the contracted power even though the electricity charge increases, but next, the same wiring system is used. There is a problem that the circuit breaker for wiring, which is affected by the amount of power consumption, drops.

That is, the wiring breaker of the distribution board is 15 to 2
It is 0A, and if this inner bath hot water cleaning device consumes 9A, not only when the capacity is 15A but also when it is 20A, if the electric equipment with large power consumption is used in the same wiring system, the wiring breaker will have a capacity Will fall over.

The bathtub hot water purifying device is provided in the bathroom, but since an outlet cannot be provided in the bathroom, it is usually connected to an outlet in the adjacent dressing room or kitchen.

Since a dressing room, a kitchen and the like are places where electric appliances having a large power consumption such as a hair dryer, a clothes dryer, a microwave oven and a hot plate are used, the bath water purifying device consumes less power. The power is taken from a large wiring system, and the wiring breaker often exceeds the capacity and falls.

For this reason, in the case of using the electric equipment with large power consumption as described above in the dressing room or the kitchen, in order to prevent the breaker for wiring from being dropped, the stopping means of the operating condition input means is used. Must be operated to stop the operation of the apparatus itself, or to operate the hot water temperature input means which also functions as an on / off switch to turn off the heater.

However, when the operation of the bath water purifying apparatus is stopped or the heating by the heater is stopped in order to use the electric equipment with large power consumption, the operating condition is resumed when the use of the electric equipment is finished. Although it is necessary to start operation or turn on the heater by operating a key as an input means, this is often forgotten.

When the operation of the apparatus is stopped or the heater is left off, the temperature of the hot water drops, and the cleaning becomes insufficient. It takes a long time to raise it, and it will not be possible to take a bath when you want to take a bath.

The present invention solves the above-mentioned drawbacks of the prior art, and even if the heater is turned off in order to use electric equipment with large power consumption, the bathtub will not forget to put in the heater and the hot water temperature will not drop. An object is to provide a hot water purifying device.

[0025]

That is, according to the present invention, the operation is performed under the control of the control means based on the operating condition input by the operating condition inputting means, and the hot water in the bathtub is sucked by the circulating pump. Various cleaning processes such as filtration of dirt in a filtration tank, heat retention by a heater, ozone sterilization by mixing ozone supplied from an ozone supply pipe, etc. In the apparatus, a heater temporary disconnection input means for temporarily disconnecting the power supply to the heater is provided in the operation condition input means, and the operation program storage means for storing the operation program according to various input conditions of the control means receives the input from the input means. Temporary disconnection heater control program storage means for storing a heater control program for temporarily disconnecting the heater in response to an input is provided. That only stored time in the temporary disconnection heater control program storage means depending on the power supply to the heater is operated is temporarily disconnected and the first claim,
In Claim 1, the program stored in the temporary cut heater control program storage means is a program for canceling the temporary heater cut operation by an input other than the input from the temporary heater cut input means by the operating condition input means. The apparatus for purifying bath water according to claim 1.

[0026]

The present invention is configured as described above, and the heater temporary disconnection input means is provided in the operating condition input means for inputting the operating conditions of various devices, and the same wiring system as the bath water purifying device is consumed. When an electric device with high power consumption is to be operated, the heater with high power consumption is cut off by operating this, and even if an electric device with high power consumption is used, the wiring breaker will not fall.

When the heater is turned off by operating the heater temporary cut input means, the heater is turned off only for a fixed time of about 1 hour set in the program stored in the temporary cut heater control program storage means of the control means. Since it is not provided, there is no possibility of forgetting to insert the water and lowering the water temperature as in the case where the water is cut using the conventional water temperature input means.

Further, when the program stored in the temporary cut heater control program storage means as in the second aspect is operated by an input means other than the heater temporary cut input means of the operating condition input means, the heater is temporarily cut. If the program is set to solve the above problem, the heater is temporarily cut off, so that the heater is always cut off for a certain period of time and it is not always necessary to return the temperature to the bathing temperature.

Thus, for example, even if the heater is temporarily cut off, if the user wants to take a bath after the use of electric equipment with large power consumption is over, he can immediately turn on the heater by operating the bath mode input means. Since the water temperature is short, the temperature of the hot water is almost unchanged and you can immediately start bathing at the appropriate temperature.

Regarding the control of the temporary heater disconnection based on the program stored in the temporary disconnection heater control program storage means 28, as shown in FIG.
A description will be given based on the flow chart of FIG.

First, referring to FIG. 2, ON-OFF by opening and closing the relay of the heater 7 via the heater drive relay circuit 30.
The control will be described. As a first step S101, the hot water temperature sensor 20 detects the temperature of the circulating hot water, and as a second step S102, the detected hot water temperature is compared with the set hot water temperature. Determine whether or not.

When the hot water temperature is determined to be equal to or higher than the set temperature as a result of the determination in the second step S102, the third step S1 is performed.
When the heater 7 is turned off in 03 and the hot water temperature is determined to be equal to or lower than the set temperature, the cutting time is set in the heater temporary cutting timer 24 in the fourth step S104 to determine whether or not the heater temporary cutting operation is being performed. It is determined by whether or not

In the fourth step S104, when it is determined that the heater temporary disconnection timer 24 has set the disconnection time and the heater temporary disconnection operation is in progress, the hot water temperature is below the set temperature but the heater 7 is turned off. When it is determined that the cutting time has not been set and the heater temporary cutting operation is not being performed, the hot water temperature is equal to or lower than the set temperature, so the heater 7 is turned on in the fifth step S105.

As described above, in the heater 7, whether the hot water temperature detected by the hot water temperature sensor 20 is equal to or higher than the set temperature, or is not higher than the set temperature, whether the cutting time is set in the heater temporary cut timer 24 or not. It is determined whether or not the heater temporary cut operation is being performed, and is turned off, and is turned on only when the hot water temperature is equal to or lower than the set temperature and the heater temporary cut timer 24 has no setting of the cutting time and the heater temporary cut operation is not being performed. Controlled as.

Next, referring to FIG. 3, the program of the input key processing in the operating condition setting means 21 which is a key input device will be explained. In the first step S201, the operating states of various input keys in the operating condition setting means 21 are read. Then, in a second step S202, it is determined whether or not the heater temporary cutting means 22 is keyed.

The display of other operating conditions corresponding to the input at 21 is turned on.

As described above, when the heater temporary disconnection operation state is entered by the input from the heater temporary disconnection input means 22 of the operation condition input means 21, this is displayed on the heater temporary disconnection display device 34 of the display device 33. It is supposed to be done.

Finally, referring to FIG. 5, heater temporary disconnection timer 2
Explaining the interrupt processing program of the timer 23 which also functions as 4, the key processing shown in FIG. 3 is performed in the first step S401, the display processing shown in FIG. 4 is performed in the second step S402, and the third step S403 is performed. Timer 2
It is determined whether or not the heater temporary disconnection timer 24 is set to 3 and the heater temporary disconnection time is set.

When it is determined in the third step S403 that the heater temporary cut time is set in the heater temporary cut timer 24, the elapsed heater temporary cut time is measured by the heater temporary cut timer 24 in the fourth step S404. However, if it is determined that the heater temporary disconnection time is not set, the time required for operation in various operation modes input by the bathing and other operation condition setting means 21 by the timer 23 in the fifth step S405, Performs timer processing such as setting time and measuring time and time.

As described above, the timer processing program is
When there is an input from the heater temporary disconnection input means 22 of the operating condition input means 21, the timer 23 immediately functions as the heater temporary disconnection timer 24 to set and measure the time required to perform the heater temporary disconnection operation. It is designed to process.

[0057]

The present invention has the above-described structure and operation, and the key input device as an operating condition input means is provided with a heater temporary cut key for temporarily turning off the heater. When the heater is operated, the heater is temporarily cut off for a disconnection time stored in the control means for about 1 hour, and an electric device with a large power consumption, such as a dryer, having the same wiring system as the bath water purifying device is connected. Even if you use, you do not have to worry that the circuit breaker for wiring will fall beyond the capacity.

Moreover, since the heater is cut off for about one hour and then automatically turned on again, the heater is turned off as in the conventional case in which the input key of the heater is operated and turned off in order to use electric equipment with large power consumption. There is no chance that you will not be able to take a bath for a long time because the heater has been turned off for a long time because you forget to put it in later, and it takes time for the bath temperature to rise to the bath temperature.

Further, even if the heater temporary cut key is operated to turn off the heater temporarily, if a key other than the heater temporary cut key is operated, the temporary cut of the heater is canceled even if the cutting time has not elapsed. Therefore, when the user wants to take a bath, the heater is immediately turned on and the heating is started by operating the bath key. Since the heater is cut off for a short time and the temperature of the hot water hardly drops, the user can immediately take a bath.
