[0002]

2. Description of the Related Art Generally, a fully-automatic bath device is combined with an electric water heater to automate the functions of filling water in a bathtub, keeping it warm, heating it (high-temperature hot water), and adding hot water. As shown in FIG. 4, this fully automatic bath device connects the electric water heater 61 and the fully automatic bath device 62 with a water supply pipe 63 and a hot water supply pipe 64, and the fully automatic bath device 62 and the bathtub 65 have circulation pipes 66. , 67, and is equipped with a remote controller 68 for an electric water heater and a remote controller 69 for a bath automatic device. The inside of the bath automatic device 62 has the following configuration. That is,
A hot and cold water mixing valve 70 is connected to a hot water supply pipe 63 and a hot water supply pipe 64 led from the electric water heater 61.
1, a check valve 72, a flow switch 73, a bath thermistor 74 and a warming heater 75 for keeping warm water in the bathtub are connected to a circulation pipe 66 connecting between the bathtub 65 and the electric water heater 61. Filling and heating (high-temperature hot water) to the bath 65 are supplied.

Here, the temperature of the supplied hot water is the bath thermistor 7
The hot water temperature is sensed at 4, and the valve opening of the hot and cold water mixing valve 70 is automatically adjusted to the hot water temperature and the bath water level indicated by the remote controller for the bath fully automatic device, and the hot water is supplied to the bath 65.

A bathtub 6 is provided in the bath automatic device 62.
A circulation path for circulating the hot water in 5 is constructed. That is, the circulation system path to the bathtub 65 is configured to be connected to the hot water supply system path via the circulation pump 76 for circulating the water in the bathtub 65, the bath water level detecting means 77, and the two-way valve 78.

The bath water temperature and the bath water level are detected by the bath thermistor 74 and the bath water level detecting means 77, and the bath temperature and the water level are maintained by the remote controller for the bath automatic device. In addition, the hot water heater 75 for keeping warm water in the bathtub is automatically started and stopped, and hot water is supplied from the supply system passage.

On the other hand, there is a 24-hour bath that can take a bath at any time as a countermeasure against such a fully automatic bath device.
In this 24-hour bath, a device for purifying the circulating water is added in order to circulate the bath water. This purifier is designed to purify by utilizing the action of microorganisms.
As shown, the bath 46, a circulation pump 47 for circulating the water in the bath 46, a filtering unit 48, a heat retaining unit 49 for circulating and retaining the water in the bath 46, a sterilizing unit 50, and three-way valves 51, 52 for switching water circuits. , 53 and two-way valves 54, 55 are arranged in the circulation path.

Then, in the filtering means 48, the suspended matter is removed and the organic matter in the water is decomposed by the filter medium 56 on which the microorganisms propagate. The hot water purified by the filtering means 48 is heated and kept warm by the warming means 49 to keep the bath water temperature constant, and then the sterilizing means 50 sterilizes the water and returns to the bathtub 46 after passing through the two-way valve 55. It is like this. (For example, JP-A-5-293458)

[0008]

However, the fully-automatic bath device has labor-saving and convenience by automating bath preparation, bath water during bathing, etc. There is no drainage function, and depending on the water level in the bathtub in front of the high-temperature hot water, the water level will be full, so it will be necessary to drain water depending on human operations. In addition, since the purification means is not configured, as shown in FIG. 6, the turbidity (dirt degree of bath water) index tends to increase as the number of people bathing increases, and unsanitary hot water is provided.

In the latter 24-hour bath, since the bath water is filtered, sterilized and kept warm, there is no need to replace the bath water and there is a great water saving effect, but it is necessary to always keep the warm state. As a result, electricity needs to be supplied for heat retention during times other than bathing, resulting in an increase in the amount of electricity used, and because the bath is always maintained at the proper temperature for bathing, it poses a problem of damaging the material of the bath. .

The present invention has solved the above-mentioned problems, and by combining the fully automatic bath function and the bath purification function,
The object is to provide a fully automatic bath device that contributes to power saving and labor saving effects.

[0011]

In order to achieve the above object, the present invention provides a water heater for supplying hot water and water, a bath automatic cleaning apparatus having a bath automatic function and a bath cleaning function, and the bath The hot water supply / water supply pipe and the circulation pipe connecting the automatic purification device and the bathtub together, and the fully automatic bath cleaning function of the bath and the remote controller for driving the bath cleaning function.

[0012]

According to the present invention, with the above-described structure, the hot water is heated from the hot water heater before the bathing time preset by the remote controller.
By supplying the heated water to the bathtub, rapid heating can be achieved and a power saving effect can be obtained, and since heating (high-temperature hot water) can be performed when necessary, an effect of suppressing damage to the bathtub material can be obtained. Further, by including the bath purification means, it is possible to incorporate the automatic drainage function of bath water according to the amount of heating (high-temperature hot water), and it is possible to provide high-quality hot water without waste.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3.

FIG. 1 is a system configuration diagram of the entire system, which is composed of an electric water heater 1 which is a water heater, a bath automatic cleaning device 2 and a bathtub 3. The bathtub 3 is filled with water and heated (high temperature). Hot water is added, and the circulation circuit between the bath automatic cleaning device 2 and the bath 3 can keep warm and clean.

This fully automatic bath apparatus is a remote controller 4 for the fully automatic bath cleaning apparatus provided in the fully automatic bath cleaning apparatus 2.
The function is controlled based on the instruction signal from the.

The above structure will be described in detail below. First, the electric water heater 1 and the bath automatic purification device 2 are connected by a water supply pipe 5 and a hot water supply pipe 6, and the bath automatic purification device 2 and the bathtub 3 are connected by circulation pipes 8 and 9. Further, the remote controller 10 for the electric water heater and the remote controller 4 for the bath automatic cleaning device are provided.

Inside the fully automatic bath cleaning device 2, a hot water supply pipe 5 and a hot water supply pipe 6 led from the electric water heater 1 are connected to a hot and cold water mixing valve 11, and a water shutoff solenoid valve 12, a check valve 13 and a float switch are provided. 14, the bath thermistor 15 and the heat retention heater 16 for heating and maintaining the bath water are connected to the circulation pipes 8 and 9 between the bath 3 and the electric water heater 1 to the bath 3
It is possible to supply hot water, heating (high-temperature hot water), and supplemental water.

Here, the hot water supplied is the bath thermistor 15
The temperature of the hot water supply is detected and the opening degree of the hot water mixing valve 11 is automatically adjusted to the hot water temperature and the bath water level instructed by the remote control 4 for the bath automatic cleaning device, and the hot water is supplied to the bath 3.

Further, the circulation system path to the bathtub 3 is a circulation pump 17 for circulating the water in the bathtub 3, a circulation pipe 8, a bath water level detection means 18, a sterilization means 19, a three-way valve 20, a filtration tank 21, and three directions. It is configured to be guided to the hot water supply system passage through the valve 22.

Further, the bath water temperature and the bath water level are detected by the bath thermistor 15 and the bath water level detecting means 18, and are maintained at the bath temperature and the water level indicated by the remote controller 4 for the bath automatic cleaning device. Therefore, while the bathing time is set, the warming and keeping of the warming heater 16 for keeping warm water in the bathtub and the addition of hot water from the supply system passage are automatically performed.

Further, before heating (high-temperature boiling water), the water in the bathtub is drained. This is done by driving the circulation pump 17 to switch the three-way valve 22 and the three-way valve 20 so that the water in the bathtub flows into the filtration tank 21. Since it flows backward from the lower side and is guided to the drainage pipe 23, the inside of the filtration tank 21 can be cleaned at the same time.

The bath water temperature is detected by the bath thermistor 15, the bath water level is detected by the water level detecting means 18, and the supplied hot water temperature is detected by the bath thermistor 15. Therefore, the hot and cold water mixing valve 11 is based on the data automatically calculated by the controller A based on those numerical values.
By adjusting the valve opening of and supplying hot water at a constant hot water temperature, the hot water temperature and water level can be set to the water temperature and the water level instructed by the remote controller 4 for the bath automatic cleaning device.

Next, the remote controller 4 for the bath automatic cleaning device shown in FIG. 2 will be described. The remote controller 4 includes a bathtub water temperature setting switch 24, a bathtub water level setting switch 25, a bubble switch 26, a liquid crystal display 27, and a bathing time reservation setting switch 28.
A liquid crystal display unit 29 and an operation switch 30 are provided and installed in the bathroom.

Next, the operation will be described with reference to FIG. Before the bathing reservation time set by the bathing time reservation setting switch 28 of the remote controller 4 for the bath automatic cleaning device, the controller A switches to the bath water drainage circuit and drains the bath water based on the calculation result. Heating (high-temperature hot water) is automatically performed, and the bath reservation time is reached at the set hot water temperature and water level. During the reserved bathing time, the bath temperature is detected by the bath thermistor 15 to keep the bath temperature and the water level, and the warming heater 16 is repeatedly turned on and off. Further, the water level of the bathtub is detected by the water level detecting means 18, and when the water level is lowered, the water level is automatically supplied from the electric water heater 1 through the supply system passage so that a constant water level is always maintained.

When the reserved bathing time period ends, only the operation of the filtration circulation path is continued and the heat retaining heater 16 and the water level recovery function are stopped. At this time, it is possible to maintain the heat retention heater 16 and the water level recovery function, and it is also possible to easily maintain the hot water temperature lower than the set value in order to suppress deterioration of the bath material.

Although an electric water heater has been described as an example of the water heater to be connected, the same effect can be obtained with a gas / oil water heater.

Furthermore, it is possible to easily form the hot water supply device and the bath automatic cleaning device integrally as an installation space / device configuration.

[0028]

As is clear from the above description, the present invention
