Abstract

(57) [Summary] [Purpose] The heater itself has a function of encouraging the user to properly use the heater. [Configuration] In addition to setting the room temperature range recommended as part of energy conservation measures, for example, between 18 and 22 ° C by raising and lowering in 1 ° C increments, and setting it to 13 ° C or 27 ° C outside that temperature range First, set the temperature from 18 ° C to the minimum setting temperature of 10 ° C, or from 22 ° C to the maximum setting temperature of 30 ° C at a stretch,
In addition, from the state of being set to the minimum or the maximum, the desired temperature of 13 ° C. or 27 ° C. is set in increments of 1 ° C. [Effect] When the set temperature is out of the recommended temperature range, the temperature displayed on the display changes drastically, so that the setter can be made aware that a certain special temperature setting is performed. Became.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a control circuit for setting a room temperature of a heater.

[0002]

[Prior Art]

 Conventionally, when setting the room temperature of a heater, when the set temperature range is, for example, a minimum temperature of 10 ° C. to a maximum temperature of 30 ° C., a temperature raising / lowering switch or the like is operated to operate 10, 11, 12 ,. Or vice versa, the setting was made in steps of 1 ° C. (Japanese Utility Model Publication No. 3359).

[0003]

[Problems to be solved by the device]

 However, in such a conventional example, when the maximum temperature is set from the state where the minimum temperature is set, or when the reverse setting is performed, the switch must be repeatedly pressed. It was very annoying.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention can set a room temperature range recommended as a part of energy saving measures, for example, between 18 and 22 ° C in 1 ° C increments, and set the set temperature range. When setting a value such as 13 ° C or 27 ° C, which is outside the range, first set 18 ° C to the minimum setting temperature of 10 ° C, or from 22 ° C to the maximum setting temperature of 30 ° C all at once. In addition, from the state where the temperature is set to the minimum or the maximum, the temperature is set to approach the desired temperature of 13 ° C or 27 ° C in steps of 1 ° C.

[0005]

[Action]

 With the above configuration, if the set temperature set by the user deviates from the recommended temperature range for energy saving, the temperature displayed on the display will change drastically. There is an effect that it is possible to inform the setter that the special temperature setting is being performed while the temperature setting is being performed in the area outside the recommended section.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a control circuit diagram of a hot air heater. In FIG. 1, 1 is a commercial power source, 2 is a burner, a fuel pump, an igniter, a fan and the like (all are not shown). The controlled unit 3 of the wind heater is a control unit composed of a microcomputer. An operation on / off switch 4, a room temperature detecting thermistor 5, a room temperature setting means 6 and a display LED 7 are connected to the control section 3. The room temperature setting means 6 is composed of a room temperature setting up switch 8 and a room temperature setting switch 9.

Next, the operation of this embodiment will be described.

FIG. 2 is an explanatory diagram of the operation of changing the set room temperature. 3 is a flow chart of the control unit 3.

First, as shown in FIG. 3, when the room temperature setting means 6 is operated to set the room temperature, the set temperature is numerically displayed on the display LED 7. When the set temperature is set between 18 ° C. and 22 ° C. by operating the room temperature setting up switch 8 or the lowering switch 9, the set temperature is set in 1 ° C. increments, which is displayed on the display LED 7.

When the room temperature setting raising switch 8 or the lowering switch 9 is kept pressed and the temperature drops from 18 ° C. to 17 ° C., for example, the set temperature suddenly reaches the minimum set value of 10 ° C. Similarly, with respect to the high temperature side, the maximum set value of 30 ° C. is reached at a stroke when the temperature rises from 22 ° C. to 23 ° C., which is displayed on the display LED 7.

After the minimum value or the maximum value is reached, if it is the minimum value, it is set in steps of 1 ° C. from 10 ° C. to 18 ° C. by operating the room temperature setting switch 8. On the other hand, when the maximum value is set, the temperature is set from 30 ° C to 22 ° C in 1 ° C increments.

[0013]

[Effect of the device]

 According to the present invention, when the set temperature set by the user deviates from the recommended temperature range for energy saving, the temperature displayed on the display changes drastically. It is possible to make the setter feel that the proper temperature setting is being performed, and it is effective in encouraging the user to properly use the heater.
