Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is used for air conditioners such as air conditioners, warm air heaters, humidifiers, dehumidifiers, etc. The present invention relates to a display method for an air conditioner in which the output is variable according to the load and the maximum output is selectable.

(B) Conventional Technology In a conventional hot air heater, for example, Japanese Patent Laid-Open No. 61-1902 is used.
As disclosed in Japanese Patent Laid-Open No. 44-44, a method is known in which the room temperature and the set temperature are compared, the combustion amount and the blowing amount of warm air are determined according to the temperature difference, and the output is made variable. Also,
Hot-air heaters with selectable maximum output have been commercialized so that they can be shared by rooms of different sizes.

By the way, in the above-described warm air heater, as shown in FIG. 5, the calorie is provided in the vicinity of the maximum output selection switch 1 of the operation unit.
(kcal / h) display was attached.

(C) Problems to be Solved by the Invention However, in the above-described conventional display method, the maximum output selection switch 1 causes 3000 kcal / h or 2300.
Even if any output of kcal / h was selected, it was difficult to understand how large the room was, and it was inconvenient to use.

This invention has been made in view of the above facts,
It is intended to display the selected maximum output with an appropriate numerical value.

(D) Means for Solving Problems In the present invention, the output such as the heat exchange amount, the combustion amount, and the air flow amount is variable according to the load, and the maximum output is selectable in the air conditioner. The maximum output is displayed as a numerical value indicating the size of the room suitable for the output.

(E) Action With this configuration, the maximum output suitable for the size of the room can be selected accurately, and the usability can be improved.

(F) Embodiments Hereinafter, embodiments of the present invention shown in the drawings will be described in detail.

FIG. 1 shows a warm air heater to which the present invention is applied. A warm air heater 2 is provided with a warm air outlet 3 at the lower front portion and an operation panel 4 is provided at the upper portion on the front side. There is.
As shown in FIG. 2, the operation panel 4 includes an output display section 6 in which ten display lamps 5 ... Of light emitting diodes are arranged side by side, a tatami mat selection switch 7, and three displays of light emitting diodes. The maximum output display section 9 in which the lamps 8A, 8B, and 8C are vertically arranged, an operation switch 10 that alternately turns on and off by repeating a pressing operation, a seesaw-type temperature setting switch 11, a current room temperature and a desired temperature A temperature indicator 12 for digitally displaying the (setting) temperature is provided. Further, the numbers attached to the sides of the display lamps 8A, 8B, and 8C indicate the size of the room suitable for the maximum output in terms of the number of tatami mats.

FIG. 3 shows an example of a control device for the hot air heater 2. The operation switch 10, the tatami mat selection switch 7, the temperature setting switch 11, and the room temperature sensor 13 such as a thermistor are connected to the input side of the microcomputer 14. It is connected to the. Further, a fuel supply pump 15, a burner motor 16, a blower motor 17, an output display unit 6, a maximum output display unit 9 and a temperature indicator 12 are connected to the output side of the microcomputer 14. An output voltage corresponding to the temperature detected by the room temperature sensor 13 is input to the microcomputer 14 via the A / D converter 18, and the A / D converter 18 may be built in the microcomputer 14. .

The maximum output of the microcomputer 14 is selected in advance by the tatami mat selection switch 7. That is, the default maximum output of the warm air heater 2 is 3300 kcal / h, and the 10-mat display lamp 8A is turned on in the maximum output display section 9. And every time the tatami mat selection switch 7 is pressed,
Selectable maximum output is 3300kcal / h → 2700kcal / h → 20
It is set in the order of 00 kcal / h → 3300 kcal / h, and the maximum output display unit 9 lights in the order of 10 tatami mat display lamp 8A → 8 tatami display lamp 8B → 6 tatami display lamp 8C → 10 tatami display lamp 8A. Further, the microcomputer 14 stores the set temperature (10 ° C. to 30 ° C.) by operating the temperature setting switch 11 and the detected temperature of the room temperature sensor 13 when the operation switch 10 is turned on, and detects the detected temperature and the detected temperature and setting. Depending on the temperature difference, the fuel pump 15 and the burner motor 16
When the room temperature at the start of operation is below a predetermined temperature (9 ° C), the output (combustion amount) is adjusted as shown in the table below. Also,
When the room temperature is higher than 9 ° C, the normal operation is performed from the beginning. Furthermore, the rotation speed of the blower motor 17 is controlled so that the amount of warm air suitable for the amount of combustion can be obtained.

Further, the microcomputer 14 apportions the magnitude of the actual combustion output between the selected maximum output and minimum output so that the display shows the maximum value (the number of lit lamps is 10) at the selected maximum combustion output. The display lamp 5 is displayed by the number of lights (1 to 10). For example, if the selected maximum combustion output is 3300 kcal / h, if the output is 3300 kcal / h, the maximum number of lamps will be 10 and the output will be 120
If it is 0 kcal / h, the number of lit lamps will be the minimum 1. If the selected maximum combustion output is 2000 kcal / h,
If the output is 2000 kcal / h, the number of lamps is 10, 1
If it is 200 kcal / h, the number of lit lamps will be 1.

According to this embodiment, the maximum output selected by the tatami mat selection switch 7 is 3300, 2700, 2000 (kcal / h).
Is a numerical value 10.8,6 indicating the size of the room suitable for the output.
Since it is displayed in (tatami), the maximum output suitable for the size of the room can be selected accurately and easily.

Although the warm air heater is described in the above embodiment, the present invention can be applied to an air conditioner such as an air conditioner, a humidifier, and a dehumidifier in which outputs such as a heat exchange amount and an air blowing amount are variable. In addition, the unit showing the size of the room is the number of tatami mats,
It may be expressed in square meters, and instead of using the display lamp as in the present embodiment, as shown in FIG. 5, numerical display may be provided near the tatami mat number selection switch 7A.

(G) Effect of the Invention Since the present invention is configured as described above, it is possible to accurately and easily select the maximum air conditioning output suitable for the size of the room, and to greatly improve usability. Is.
