Abstract

PURPOSE:To permit an user to use a hot-water supplier economically and obtain a necessary high temperature as he desires by a method wherein a hot-water supplier ignition switch, capable of operating the combustion and stop of the hotwater supplier by the will of the user, is provided at a remote control unit. CONSTITUTION:Three-way switch circuit is formed between a main remote controller 13 and a bath remote controller 16 in the remote control unit. In case the temperature of hot-water in the hot-water reserving tank 1 is the temperature not necessitating heating, the user can use the hot-water from the tank 1 by putting the hot-water supplying operation switch 19 of the main remote controller 16 or the hot-water supplying operation switch 20 of the bath remote controller 16 OFF and without operating the hot-water supplier. On the contrary, in case the temperature of the same from the tank 1 is too low, the user can operate the hot-water supplier and use the hot-water of proper temperature by putting the hot-water supplying operation switch 1 of the main remote controller 13 or the same switch 20 of the bath remote controller 16 ON. In this case, a high temperature, in which temperature a boiling preventing device is operated, may be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a water heater for an auxiliary heat source in a solar system and an operating mechanism for a water heater in a solar-connected hot water bath device that integrates a bath pot.

Construction of a conventional example and its problems FIG. 1 is an overall construction diagram of a conventional solar-connected hot water bath apparatus. In Figure 1, 1 is a solar heat storage] tank, 2 is a thermistor that detects the temperature of water entering from heat storage J + Qj 1, 3 is a water flow switch that detects whether water is flowing into the water heater,
4 is a control circuit for controlling the equipment, 5 is a heat exchanger for hot water supply, 6 is a heating device for hot water supply, 7 is a solenoid valve for hot water supply, 8 is a heat exchanger for filtering, 9 is a heating device for filtering, 10 Solenoid valve for Hafuro, 11 is the original solenoid valve, 12 is the pilot burner, 13 is the main remote control, power switch 14 and hot water temperature control knob 15
It is equipped with 16 is fed by bath remote control? gJ Nagisa is equipped with a degree adjustment knob 17 and a swing operation switch 7 and 18.

When the power switch 14 of the main remote controller 13 is turned on and the water heater is opened, heat is stored in the water heater (water flows from the protrusion 1 and the flow of water is detected by the water flow switch 3).

Thermistor 2 detects the inlet water temperature. If the inlet water temperature is set at noon to stop combustion, a signal is issued from the control circuit 4, and at the same time the main solenoid valve 11 opens, discharge begins, the pilot burner is ignited, and the hot water supply solenoid valve 7 opens to supply hot water. Heating energy is sent to the heating device 6 to operate the water heater.

If the temperature of the water entering from the heat storage tank 1 stops combustion and exceeds the membrane set temperature, no signal will be output from the control circuit 4.
I don't drive.

Here, the inlet water temperature at which combustion in the water heater stops is t'C.

If the set temperature t'C is high, for example 50℃, and the inlet water temperature is 45℃, even if the user thinks that 45℃ is the appropriate temperature or hot, the water heater will burn and become even hotter, resulting in wasted water. Gas is used, which is uneconomical. By the way, the plate? The optimum temperature when the sun is shining is said to be approximately 37°C.

If the set temperature t'C is low, for example 50℃, and the inlet water temperature is 55℃, the water heater will not burn even if the user wants a higher temperature, making it very difficult to use. .

As can be seen from the above, no matter how many times the set temperature t°C was set, it was not possible to satisfy both economical efficiency and usability.

By turning off the power, it is possible to stop the combustion of hot water, but in this case, the combustion of the bath becomes impossible, and it cannot be used at the same time as the hot water supply.

OBJECTS OF THE INVENTION The present invention overcomes the above-mentioned drawbacks of the prior art and aims to enable the user to use the water heater more economically while still achieving the desired high temperature.

Structure of the Invention In order to achieve the above-mentioned object, the present invention adds a hot water combustion switch to the remote control unit, which allows the user to control the combustion and stopping of the water heater according to his/her will. This remote control also forms a three-way switch circuit between the main remote control and the full remote control.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. As in the past, there is a running water switch 3, a control circuit 4, a hot water heat exchanger 5, a hot water heating device 6, a hot water solenoid valve 7, a bath heat exchanger 8, a bath heating device 9, a bath solenoid valve 10, The main remote control 13 is equipped with a power switch 14, a hot water temperature adjustment knob 15, and a hot water supply operation switch 19.The full remote control 16 is equipped with a hot water supply operation switch 19. A hot water supply operation switch 2o is provided in addition to a temperature adjustment knob 17 and a shift operation switch 18. A boiling prevention device 21 is also provided at the outlet of the hot water supply heat exchanger.

If the water from the heat storage tank 1 is at a temperature that does not require heating, the user of the water heater operates the water heater by turning off the hot water supply operation switch 19 on the main remote controller 13' or the hot water supply operation switch 20 on the remote controller 16. Hot water from the heat storage tank 1 can be used without any problems.

Conversely, if the temperature from the heat storage tank 1 is lukewarm, press the hot water supply operation switch 19 of the main remote controller 13 or the remote controller 16.
By turning on the hot water supply operation switch 2o, the water heater can be operated and hot water at an appropriate temperature can be used. in this case,
High temperatures can be used until the boiling prevention device is activated.

Further, the hot water supply operation switch 19 of the main remote controller 13 and the colon operation switch 20 of the bath remote controller 16 form a three-way switch circuit, and can be operated from either remote controller.

Effect of the invention The present invention provides the following effects.

(1) The iMk can be started and stopped at the discretion of the water heater user, and wasteful use of gas can be avoided.

(A wide range of temperatures can be used, from the high temperature until the 21i!Ili rise prevention device is activated, to the temperature of the heat storage tank water.

(3) A boiling prevention device is also attached to a conventional water heater, and FIG. 1 is an overall configuration diagram of the conventional example, and FIG. 2 is an overall configuration diagram of an embodiment of the present invention.
