Description

The present invention relates to a remote control device for gas appliances such as a water heater, a water heater with a bath reheating function, and a fully automatic bath device with a water heating function.

[Conventional technology]

In a gas appliance as described above, for example, a fully automatic bath apparatus, when the operation switch is turned on after setting the filling water level and temperature in the bath tub on the remote control device, hot water heated by the hot water supply heat exchanger is poured into the bath tub. It is configured to automatically stop pouring when hot water reaches a set water level and perform reheating operation by a reheating heat exchanger when the temperature of hot water in the bathtub does not reach the set temperature. .

[Problems to be solved by the invention]

However, in the conventional remote control device (remote control), display characters, graphics, and the like on the display unit are fixed, and when changing the design of the display unit, it is necessary to change the entire remote control device.

In addition, even if gas equipment of the same model has an optional function, for example, with and without a clock, with a telecontroller (one that controls gas equipment by a telephone line) and without a telecontroller, Separate remote control devices must be prepared.

Further, in the conventional remote control device, since the design of the display unit is fixed, it is not possible to change and display a driving state or the like.

The present invention solves the above-mentioned problems of the prior art, and enables remote control of a gas appliance that can be used commonly for gas appliances having a plurality of different functions by changing the design, characters, and graphics of the display unit. It is an object to provide an operation device.

[Means for solving the problem]

The present invention, in order to achieve the object as described above, comprises a control board on the gas appliance body side, a hand operation unit, and a connection wire for connecting the control board and the hand operation unit on the gas appliance body side, The hand operation unit transmits and receives signals to and from a dot matrix liquid crystal display panel and a dot matrix transparent touch switch sheet, a control circuit for controlling the liquid crystal display panel and the touch switch sheet, and a control board on the gas appliance body side. A control circuit for transmitting and receiving signals to and from the hand operation unit, and a plurality of displays corresponding to operations of a plurality of gas appliances having different functions. A storage circuit storing a pattern, and when a specific display pattern is designated by the touch switch sheet, the display read out from the storage circuit of the gas appliance main body. Displays turn on the liquid crystal display panel of the operation portion, and is characterized in that a gas appliance was no order to the remote control according to the operation of the touch switch sheet corresponding to the display.

[Action]

As described above, the present invention includes a storage circuit storing a plurality of display patterns corresponding to operations of a plurality of gas appliances having different models on the control board of the gas appliance main body. When a specific display pattern is designated by the switch sheet, a display pattern corresponding to a desired operation of the gas appliance read from the storage circuit of the gas appliance main body is displayed on the liquid crystal display panel of the hand operation unit, and a touch on the display is performed. The gas equipment can be remotely controlled according to the operation of the switch sheet.

Therefore, according to the present invention, it is possible to operate a plurality of types of gas appliances with one type of remote control without requiring a dedicated remote control (hand operation unit) for each appliance. There is no need to buy a remote control even if you change the equipment from a water heater with a heating function to a fully automatic bath apparatus with a water heating function.

FIG. 5 shows an example of a water heater having a function of reheating the hot water in the bathtub, in which an operation button, a column for indicating that reheating is in progress, a number indicating the temperature of the bathtub hot water, and an increase thereof. A down switch, a column indicating that hot water is being supplied, a number indicating hot water temperature, and an up / down switch for setting hot water temperature are displayed.

6 (A) to 6 (F) show an example applied to a fully automatic bath apparatus with a hot water supply function.

When you select the pattern for the fully automatic bath equipment,
As shown in FIG. 7A, the operation button and the setting change button, and the set hot water supply temperature, bath temperature, and bathtub water level are displayed. (Note that the portion surrounded by spots in FIG. 6 indicates that an input is accepted.) In this state, when the setting change button is pressed, the display is changed, for example, as shown in FIG. 6 (B). . That is, a hot water supply temperature change button, a bath temperature change button, a bathtub water level change button, an up / down button, and other and end buttons are displayed, and the respective temperatures and water levels at that time are displayed by numerals, and this state is displayed. In "hot water temperature"
The set number can be changed by pressing any button of “bath temperature” and “bath water level” and operating the up / down switch. When the setting of the temperature and the water level is completed, when the “end” button is pressed, the screen returns to the initial screen shown in FIG. 6 (A).

Further, when the driving button is pressed in the state shown in FIG. 6 (A), the display is changed as shown in FIG. 6 (C), for example. That is, a full-automatic operation button, a bath operation button, a collecting button, a luke button, a stop button, and a setting change button are displayed. When the fully-automatic button is pressed in this state, the display on the liquid crystal panel becomes the sixth. As shown in FIG. 3D, the display is changed to a display indicating the state of the fully automatic operation, the automatic operation is continued, and when the filling of the set water level and the set temperature is completed, the operation is shifted to the heat retaining operation and the state is changed. It is displayed as shown in FIG.

At this time, when the hot water temperature in the bathtub becomes lower than the set value, the reheating operation is automatically performed, and when the bathtub water level becomes lower than the set water level, the hot water is automatically supplied to the bathtub to the set water level as in the conventional case. is there.

When a certain period of time, for example, 4 hours, has elapsed since the start of the fully automatic operation, or when the stop button is pressed, the display on the liquid crystal panel is changed as shown in, for example, FIG. 6 (F). At this time, the bathtub water level changes from the current state. Is shown.
