Abstract

PURPOSE:To allow the user to identify the hot water supply temperature in advance whichever tap he or she may desire to to use to supply the hot water so as to prevent burn injuries due to a careless opening of the tap by imposing that only one remote controller out of a plurality of remote controllers becomes effective and nullifying all others at the time of switching the hot water supply temperature, and causing only the indicator lamps for hot water supply temperature to be illuminated on the nullified remote controllers. CONSTITUTION:At the time of switching the hot water supply temperature, only one of a plurality of remote controllers A, B is always made effective and others are nullified. On the temperature indicator 12 on the effective remote controller A, all the lamps from the 'low' to the set level are illuminated, and, on the temperature indicators on the nullified remote controllers B, only the lamp for the set level is illuminated. In this constitution, the set temperature for hot water delivery is indicated not only on the prioritized remote controller A but also on the non-prioritized remote controllers B, and so, the hot water supply temperature can be identified in advance whichever tap is to be used, preventing burn injuries due to a careless opening of the tap.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a water heater that has a plurality of remote controllers and performs preliminary hot water supply.

Conventional technology A conventional water heater will be explained using FIG. 2.

1 is a water supply pipe, which is connected to a heat exchanger 3 via a pressure reducing valve 2. A faucet 5 is connected to the heat exchanger 3 via a hot water pipe 4.
And it is connected to the faucet 6. 7 is a burner, 8 is a hot water temperature detector, and 9 is a controller that controls the operation. 10
is the first remote control, 15 is the second remote control, 11 and 11''
12 and 12' are hot water temperature display devices, 13 and 13° are priority selector switches, and 14 and 14' are operation switches. A first remote control cable 16 connects the controller 9 and the first remote control 10.
A second remote control cable 17 connects the controller 9 and the second remote control 15. The first remote control lO is faucet 5
The second remote controller 15 is installed at a location corresponding to the faucet 6.

When the operation switch 14 and the priority changeover switch 13 are turned on, the operation of the hot water temperature setting switch 11 becomes valid and the hot water temperature can be set. If the setting scale is set to "4", the lamps from "low" to "4" on the hot water temperature display 12 will light up, and the burner 7 will operate to drain the water in the heat exchanger 3. Heat to set value. When the set value is reached, the burner 7 is stopped by a signal from the hot water temperature detector 8. After that, when the faucet 5 is opened, hot water is dispensed at a temperature set by the water pressure. When the water temperature drops below the set value, the water temperature detector 8
The burner 7 is operated again by the signal, and the water temperature is maintained at the set value. In this way, hot water is supplied at the desired temperature.

At this time, all the lamps of the hot water temperature display 12' of the second remote controller 15, which is in a non-priority state and whose operation is disabled, are turned off. In this state, turn the priority switch 13 of the second remote controller 15 to
When set to N, the operability and display of the first remote controller 10 and the second remote controller 15 are reversed, and the second remote controller becomes effective.

Problem to be Solved by the Invention However, with the above configuration, the setting value cannot be determined because all the 12° lamps of the hot water temperature display are off in the second remote controller which is in the non-priority state, but if the corresponding faucet 6 is opened, the setting value cannot be determined. , the hot water is dispensed from the faucet 6 at the temperature set with the first remote controller. If the first remote controller had been used to set the temperature to a high temperature at this time, there would have been a problem of burn injuries.

The present invention solves the above problems and provides a highly safe water heater that prevents burn accidents by making it possible to identify the set hot water temperature even on the non-priority side remote controller.

Means for Solving the Problems In order to solve the above problems, the water heater of the present invention is provided with a water heater main body that can vary the temperature of hot water, a hot water temperature setting switch, and a hot water temperature display consisting of a plurality of lamps. The hot water temperature switching operation is always performed using one of the multiple remote controllers.
At the same time, the hot water temperature display installed on the remote control with operation enabled lights up all the lamps from "low" to the set value, and the other remote control with operation disabled lights up. The water temperature indicator provided is set.

This configuration includes a controller that lights only the value lamp.

Operation Due to the above configuration, not only the priority side remote control, but also the
Since the set value of the hot water temperature is displayed on the non-priority side remote control as well, the hot water temperature can be identified in advance no matter which faucet is used to dispense hot water, thereby preventing burn injuries caused by careless faucet operation.

Embodiment Hereinafter, a water heater according to an embodiment of the present invention will be explained with reference to the drawings.

Since the main body of the water heater and the configuration of the plurality of remote controllers are the same as those of the conventional example, their explanation will be omitted, and the explanation will focus on the operation of the hot water temperature indicator, which is the key point of the present invention.

FIG. 1 shows the operating state with the operation switch 14 turned on, and A
indicates a remote controller in a state where priority is given, the operation of the hot water temperature setting switch 11 is valid, and the scale is set to "4". At this time, all the lamps from "low" to "4" on the hot water temperature display 12 are lit to display the set value. When the "Lukewarm" button on the hot water temperature setting switch 11 is pressed, the set value moves to "3" and the "4" lamp on the hot water temperature display 12 turns off.

Further, when the user presses the "hot" button, the set value moves to "5" and the "5" lamp on the hot water temperature display 12 lights up. In this way, the hot water temperature set value is displayed, and the user is informed of the hot water temperature from the faucet 5.6.

On the other hand, B in FIG. 1 is a non-priority mode and the hot water temperature setting switch 11
Indicates a remote controller in which the setting value does not change even if the operation is disabled.When the scale is set to "4" on the priority remote controller, the hot water temperature display 12 corresponds to the scale of "4". Light.

"Lukewarm" of hot water temperature setting switch 11 on the priority side remote control
Press to move the set value to "3", and the water temperature display 1
The lighting position of lamp 2 moves from "4" to "3". In this way, the hot water temperature display 12 on the non-priority side lights up only the set value, and moves according to the set value to notify the user of the faucet 5.
．． In addition to letting you know the hot water temperature from 6, it also tells you whether it is a priority.
It also displays whether it is a non-priority item or not.

Effects of the Invention The present invention has the following excellent effects.

In other words, the hot water temperature is displayed on all remote controllers, regardless of priority or non-priority, and the user can hear the sound of hot water coming from any faucet, which prevents burn injuries caused by careless faucet operation. It is possible.
