In addition, e is a combustion lamp which lights up when the burner is ignited, and f is an error display lamp which indicates an abnormality of the device or the like.

[Problems to be solved by the invention]

The conventional remote control for a water heater has the above-described configuration, and is configured so as to obtain hot water of a set hot water temperature as desired. However, it is determined whether the hot water temperature actually discharged is the set hot water temperature. It was not possible to confirm whether the temperature had reached the set temperature after a certain period of time, but it was not possible to know when the set temperature was reached.

For this reason, for example, when the shower is frequently used, only the set temperature is known even when the water or hot water is initially generated due to use or non-use of the appliance before the shower, so that the water or hot water is initially generated. There is danger.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and to provide a remote control for a water heater that can be used after confirming an actual tapping temperature.

Another object of the present invention is to provide a remote control for a water heater that makes it easy to check the actual hot water temperature.

[Means for solving the problem]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a remote control for hot water supply having an operation switch, a hot water temperature setting switch, and a set temperature character display section for displaying a temperature set by the hot water temperature setting switch in characters. A set temperature color display unit for emitting and displaying the set temperature set by the hot water supply temperature setting switch as a change in color; and a substantial tapping temperature for detecting the temperature of the hot water during tapping and displaying the temperature as a change in color. A color display unit, and the substantial hot water color display unit is a three-dimensional color display unit that can be visually recognized even from directions other than the front.

[Action]

As described above, according to the present invention, a remote controller has a set temperature color display section for emitting and displaying a set temperature set by a hot water supply temperature setting switch as a change in color, and detecting a hot water temperature during tapping to determine the temperature. Since the actual hot water temperature color display section that displays light emission as a change is provided, if the color of the set temperature color display section and the color of the real hot water temperature color display section are different, it is directly visually recognized that the hot water temperature is not the set temperature. Can also
If they are the same, it is possible to immediately know that the tap water temperature has become equal to the set temperature.

Further, since the real hot water warm color display section is a three-dimensional color display section, light from the color display section is radiated in all directions except the front, and even at a position remote from the remote control, for example, in a shower. Can be visually recognized as an inappropriately high temperature.

〔Example〕

One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 (a) is a front view of a remote controller showing an embodiment of the present invention, and FIG. 1 (b) is a side view thereof.

a is an operation switch similar to that shown in the conventional example,
b and c are also up-down type hot water supply temperature setting switches,
"d" is a set temperature display unit also using characters.

In the present invention, in addition to the set temperature display section d, a set temperature color display section g that emits light by displaying the temperature setting as a change in color, and detects the temperature of the hot water during tapping and uses the hot water temperature as a change in color. And a real hot water color display h for displaying light emission.

The set temperature color display part g may be a flat surface like a conventional remote controller, but may be a three-dimensional display part.
As shown in FIG. 1 (b), the real hot water warm color display section h
A three-dimensional display unit that can be visually recognized from directions other than the front side by, for example, protruding from the surface of the remote controller.

Although the specific configurations of the set temperature color display portion g and the actual hot water temperature color display portion h are not shown, light-emitting diodes of at least three colors are incorporated in a remote controller, and these light-emitting diodes are separately used. Alternatively, the display color may be changed by emitting light in combination, or a colored filter may be provided on the front surface of the white light emitting diode, and the display color may be changed by rotating the filter. Can be.

Further, the change of the temperature and the color of the set temperature color display section g and the actual hot water color display section h are set as shown in FIG. 2, for example.

That is, the water temperature is green, 36 ° C to 37 ° C indicates a yellowish green color, 39 ° C to 42 ° C indicates yellow and a standard temperature, and 43 ° C to 46 ° C is orange. To indicate that it is hot, and to indicate that it is dangerous if the temperature is 60 ° C or more, is red. Although the simplest example is shown in FIG. 2, a change in color can be further finely adjusted by a combination of light emitting diodes and a change in luminous intensity thereof, or by using a filter.

When controlling the water heater with two remote controls, one in the kitchen and the other in the bathroom,
There is a risk of burns when using a shower in the bathroom while using hot water in the kitchen. For this reason, the prior art remote control installed in the bathroom is provided with a priority switch which can set the temperature preferentially. However, if you use the shower without pressing this priority switch, it is the same as there is no priority switch, and if you consider the safety of the user, you should positively notify that it is in a hot water tap state It is.

However, conventionally, since it was not possible to check the tapping temperature except in front of the remote controller, there was a danger of using the shower without pressing the priority switch as described above. On the other hand, in the present invention, since the hot water warm color display portion h is made three-dimensional, it is dangerous that the red light from the display portion h is easily visually recognized even at a position remote from the remote controller. It is possible to know immediately, thereby reducing forgetting to press the priority switch.

〔The invention's effect〕

As described above, according to the present invention, the set temperature set by the hot water supply temperature setting switch is displayed as a change in color to emit light, and the actual outlet temperature of the water heater is detected and displayed as a change in color. Therefore, it is possible to immediately know the set temperature and the tapping temperature based on the difference in the colors of the two light emitting display units, and to set the actual tapping temperature color display unit in a three-dimensional manner so that the unit is located far from the remote controller. The temperature of the hot water can be known very easily, and the safety can be improved.
