Abstract

PURPOSE:To provide a bath hot water feeding device for generating an instruction to feed hot water from an external location to a bath tub through a telephone network in which a hot water feeding at the most appropriate specified temperature can be performed automatically as well as positively and safely whatever a temperature set value of the remote controller in a house may be of any deg.C. CONSTITUTION:As a hot water feeding start signal is given to a bath hot water feeding device through a tele-control system from an external location, a valve means 2 is opened and hot water is supplied to a bath tub 4. At this time, a temperature changing-over means 7 is operated in cooperation with the hot water feeding starting signal. A temperature set value given to a temperature controller of the hot water feeder 1 for use in controlling hot water temperature is changed over from the temperature set value to the fixed temperature set value through the remote controller 8 normally used and then hot water is fed into the bath tub at the most suitable specified hot water temperature.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath water supply device that automatically supplies hot water to a bathtub by issuing a command to supply hot water to the bathtub from outside using a telephone line.

2. Description of the Related Art Conventional bath water supply devices are generally capable of remotely controlling the supply of hot water to a bathtub from a remote control installed in another room in the house. On the other hand, recently, attempts have been made to transmit control signals using telephone lines and remotely control objects to be controlled. One of these is the teleconverter function, which is a function of HA (home automation), and is already implemented in some electrical equipment. In this modern world, there is a growing need in the field of bath water supply to boil a bath from outside using a telephone line.

[Problems to be Solved by the Invention] However, when hot water is supplied to a bath using a teleconverter, particularly reliable and safe operation is required since no one is present. Incidentally, normally, the hot water temperature of a water heater is set by a remote control, and the hot water temperature can be varied over a wide range, for example, from 36° C. to 80° C. Hot water at a high temperature of 80 degrees Celsius is often used in the kitchen to wash oil-covered dishes, and in the bathroom to pour hot water into the bathtub. Therefore, it is quite conceivable that the water heater may be used at a high temperature setting of 80° C., and then go out with the high temperature setting. In such a case, if hot water is supplied to the bathtub using a teleconverter, 80°C hot water will be supplied to the bathtub, resulting in a waste of energy. Also, if you want to take a bath as soon as you get home and you operate the water heater remotely from outside and take a bath in a relatively short time, the 80℃ hot water as mentioned above will fill the bathtub. If there is, you won't be able to take a bath right away, and if you take a bath without checking carefully, there is a risk of getting burned. Accidents that would not occur when using a conventional water heater, or errors in operation can be easily corrected. The problem was that there was no.

[0004] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a bath water supply device that can safely and reliably supply hot water to a bath using a telecontroller from outside the home.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the bath water supply device of the present invention includes a telecontroller that operates in response to a hot water supply start signal transmitted using a telephone line;
A water heater that heats and dispenses tap water, a temperature control controller that controls the hot water temperature of the water heater to a set temperature, and a valve means provided on the hot water output side of the water heater that turns on and off the hot water supply; A remote controller that freely sets the hot water temperature by operation from within the same house, a fixed temperature setting means that sets the hot water temperature to a predetermined fixed temperature, and a temperature setting value set by the remote controller and fixed by the fixed temperature setting means. comprising a temperature switching means for selectively switching a temperature setting value, and when this temperature switching means receives a hot water supply start signal from the telecontroller, it provides the fixed temperature setting by the fixed temperature setting means to the temperature control controller; The structure is such that hot water is supplied to the bath at a fixed temperature.

[0006]

[Operation] With the above configuration, when hot water is supplied to a bath using a teleconverter function using a telephone line from outside,
No matter what temperature setting is set on the remote controller in the house, it is possible to always supply hot water at a fixed temperature suitable for bath water supply.

[0007]

Embodiment An embodiment of the system of the present invention will be described below with reference to FIG. Reference numeral 1 is an instantaneous gas water heater, which automatically ignites gas and supplies hot water by opening a faucet installed on the hot water outlet side and letting water flow. Reference numeral 2 denotes a valve means realized by a solenoid valve or the like, and the hot water output and stoppage from the gas water heater 1 can be controlled by an on/off signal (ONOF signal) from the timer means 6. Reference numeral 3 denotes an automatic water stop means, in which a metered water stop valve is used in the embodiment, and the integrated value of the amount of hot water supplied when the valve means 2 is turned on and hot water is supplied to the bathtub 4 reaches a preset value. It can be stopped automatically. It goes without saying that the automatic water stop means may be any other means that detects the water level in the bathtub 4 and automatically stops the water. Reference numeral 5 denotes a telecontroller, which receives a bath hot water supply command transmitted from the outside using the telephone line T, and outputs a hot water supply start signal (STRT signal) for triggering the timer means. The timer means 6 sends an on/off signal (ONOF signal) to the above-mentioned valve means 2.
In addition, a temperature switching signal (CHNG signal) is sent to the temperature switching means 7.
Output. Note that the ONOF signal and the CHNG signal may be the same signal, and in this embodiment, the ONOF signal and the CHNG signal are output from the timer means 6, but they may be output directly from the telecontroller 5. Needless to say.

The temperature switching means 7 changes the temperature setting signal (TSET signal) to the gas water heater 1 to a setting value (TVAL signal) from the remote controller 8 or to a fixed setting value exclusively for bath water supply (TFIX signal). signal). FIG. 2 shows a conceptual diagram of the temperature switching means 7. 9 is a fixed temperature setting means composed of a circuit for producing a fixed temperature setting value (TFIX signal), and the temperature switching signal (CH
The TFIX signal and the TVAL signal are switched by the NG signal). In addition, the temperature switching by the temperature switching means 7 is as follows.
In the case of remote control from within the same house using the remote controller 8, the TVAL signal is sent to the telephone line T using the telecontroller 5.
In the case of remote control using , the configuration is such that the TFIX signal is selected.

The switched temperature setpoint signal is TSET
The signal is given to the combustion controller 12 as a temperature control controller of the gas water heater 1, and compared with the hot water outlet temperature signal (WTMP signal) detected by the hot water outlet thermistor 10, the combustion of the gas is controlled and the hot water temperature is adjusted. Controlled to the set value. 11 is a gas combustor.

[0010] According to the configuration of this embodiment, when hot water for a bath is supplied by a teleconverter using a telephone line from outside the home, the fixed value most suitable for hot water supply for the bath is always set, regardless of the hot water temperature setting value set by the remote control in the house. Since the hot water is supplied at a temperature of 200 ft, it is possible to prevent energy wastage due to incorrect settings such as setting a high temperature, and the risk of accidentally taking a hot bath.

[0011]

[Effects of the Invention] As explained above, the bath hot water supply device of the present invention can be used to supply hot water to a bath using a telephone line using a telecontrol system from outside the house. Even if there is a problem, the bathtub can be automatically filled with hot water at a constant temperature most suitable for bath water supply, resulting in the following effects. (1) Generally speaking, if you supply bath water at 80 degrees Celsius when it should normally be around 40 degrees Celsius, you will waste energy for the difference in temperature; however, according to the bath water supply device of the present invention, this It is possible to prevent such wastage of energy. (2) Generally speaking, if you want to take a bath immediately after returning home, and you operate the telecontrol system from outside and take a bath immediately after returning home, the temperature setting of the water heater may be accidentally set to 80℃. If the temperature is set and the water is filled with 80℃ water, you will need to add water to lower the temperature.
It is a waste of time as well as a waste of energy. On the contrary, 36
If hot water is accidentally filled at a low temperature such as ℃,
This creates a time-consuming situation where you cannot take a bath without reheating the heat or pouring hot water.

However, the present invention can prevent such waste of energy and time and provide a truly convenient bath water heater that matches the lifestyle of modern people who try to use their time effectively. (3) Furthermore, in general, if the hot water temperature setting of the water heater is set to a high temperature and you fill the bathtub with 80℃ water using the telecontrol system from outside, check carefully before taking a bath or you may get burned. Dangerous situations such as these are also possible. For example, if a small child takes a bath alone, there is a risk of a very serious accident.

[0013] The present invention can prevent such dangerous situations and provide a bath water supply device that allows bathing at any time with peace of mind.
