Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is used in 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 Conventionally, in a hot air heater, for example, as disclosed in Japanese Patent Laid-Open No. 61-190244, room temperature is compared with a set temperature, and a combustion amount is determined according to the temperature difference. It is known that the amount of warm air blown is determined and the output is made variable. In addition, hot air heaters that have the maximum output selectable have been commercialized so that they can be shared by rooms of different sizes.

By the way, in the above-mentioned warm air heater, as shown in FIG. 5, a calorie (kcal / h) display is provided in the vicinity of the maximum output selection switch 1 of the operation unit, and the output of the warm air heater is shown. The output display unit 2 was provided. And out of the maximum output that can be selected (3000kcal / h or 2300kcal / h),
According to the ratio of the output of the warm air heater to the maximum output (3000kcal / h), the size of the output was displayed by the number of lamps lit.

(C) Problems to be solved by the invention However, in the above-described conventional display method, when 2300 kcal / h is selected by the maximum output selection switch, even if the heating load is large and the output is 2300 kcal / h, ,
Since seven out of ten lamps are not turned on, there is a drawback that it is not easy to use, such as giving the customer an unpleasant feeling that "it is cold but not burning at maximum output".

This invention has been made in view of the above facts,
The purpose of the present invention is to provide an appropriate output display in an air conditioner in which the maximum output can be set.

(D) Means for Solving the Problems In the present invention, the output such as the heat exchange amount, the combustion amount, and the blown air amount can be changed according to the load, and the maximum output can be selected. The maximum output is displayed, and the output of the air conditioner is displayed according to the ratio of the output of the air conditioner to the selected maximum output.

(E) Action With this configuration, not only is the magnitude of the selected maximum output displayed and it is possible to know whether or not the maximum output is properly selected, but also the output of the air conditioner with respect to the selected maximum output. Since the size of the air conditioner output according to the ratio is displayed, if the air conditioning load is large and the output of the air conditioner is the selected maximum output, for example, 100% will be displayed, The size of the output of the air conditioner with respect to the selected maximum output can be known regardless of the size of the selected maximum output, and the usability is improved.

(F) Embodiment 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, in which a warm air outlet 4 is provided at the lower front portion of the warm air heater 3, and an operation panel 5 is provided at the upper portion on the front side. There is.
As shown in FIG. 2, the operation panel 5 includes an output display section 7 in which ten display lamps 6 ... Composed of light emitting diodes are arranged side by side, a tatami mat selection switch 8 and three display composed of light emitting diodes. Maximum output display with lamps 9A, 9B, 9C arranged vertically
10, operation switch 11 that alternately turns on and off by repeated pressing operation, and seesaw type temperature setting switch 12
And a temperature indicator 13 for digitally displaying the present room temperature and the desired (set) temperature. Also, the indicator lamp 9
The numbers next to A, 9B and 9C indicate the size of the room suitable for maximum output in tatami mats.

FIG. 3 shows an example of a control device for the hot air heater 3. The operation switch 11, the tatami mat selection switch 8, the temperature setting switch 12, and the room temperature sensor 14 such as a thermistor are connected to the input side of the microcomputer 15. It is connected to the. Further, a fuel supply pump 16, a burner motor 17, a blower motor 18, an output display section 7, a maximum output display section 10 and a temperature display 13 are connected to the output side of the microcomputer 15. In addition, the output voltage according to the temperature detected by the room temperature sensor 14 is A / D converter 19
Is input to the microcomputer 15 via
The D converter 19 may be built in the microcomputer 15.

The maximum output of the microcomputer 15 is selected in advance by the tatami mat selection switch 8. That is, the default maximum output of the warm air heater 3 is 3300 kcal / h, and the 10-mat display lamp 9A is turned on in the maximum output display section 10. Then, each time the tatami mat selection switch 8 is pressed, the selected maximum output is 3300 kcal / h → 2700 kcal / h → 2000 kcal / h → 3300 kcal / h
It is set in the order of, and the maximum output display section 10 has 10 tatami mat display lamps.
9A → 8 tatami indicator lamp 9B → 6 tatami indicator lamp 9C → 10 tatami indicator lamp 9A lights in this order. In addition, the microcomputer 15
Stores the set temperature (10 ° C to 30 ° C) detected by the temperature setting switch 12 and the temperature detected by the room temperature sensor 14 when the operation switch 11 is turned on, and detects the detected temperature and the difference between the detected temperature and the set temperature. Accordingly, the fuel pump 16 and the burner motor 17 are controlled, and the output (combustion amount) is adjusted as shown in the table below when the room temperature at the start of operation is lower than a predetermined temperature (9 ° C.). When the room temperature is higher than 9 ° C, normal operation is performed from the beginning. Furthermore, the rotation speed of the blower motor 18 is controlled so that the amount of warm air suitable for the amount of combustion can be obtained.

Further, as shown in FIG.
When the output is the selected maximum combustion output, the display shows the maximum value (10 lamps lit) so that the magnitude of the combustion output is proportionally divided between the selected maximum output and minimum output. Displayed by the number of lights (... 1). For example, if the selected maximum combustion output is 300 kcal / h, the output is 3300 kcal / h.
With h, the maximum number of lamps will be 10, and the output will be 1200k.
If cal / h, the minimum number of lamps that can be lit is 1. Further, when the selected maximum combustion output is 2000 kcal / h, if the output is 2000 kcal / h, the number of lamp lighting is 10, and if it is 1200 kcal / h, the number of lamp lighting is 1.

According to the present embodiment, the selected maximum output magnitude is displayed on the maximum output display unit 10 and it is possible to not only know whether the maximum output is properly selected but also the selected maximum output magnitude. Regardless, the selected maximum output is set as the maximum value of display (10 lamps), and the output of the warm air heater is displayed by the number of lamps (1-10). Output is 2700kcal / h and 2000kcal, respectively, even when limited to 2700kcal / h and 2000kcal / h
If it is / h, it will be displayed in full scale with 10 lamps lit, and you can see how much output is being output relative to the selected maximum output, improving usability.

In addition, although the warm air heater has been described in the above-described embodiments, 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. Further, although the magnitude of the output is displayed by the number of lit lamps, it may be displayed by using a digital display or a graphic display. Furthermore, although the maximum output is manually selected, it may be automatically selected according to the load.

(G) Effect of the Invention Since the present invention is configured as described above, not only is the magnitude of the selected maximum output displayed and it is possible to know whether or not the maximum output is properly selected, Regardless of the maximum output power, it is possible to know how much the air conditioner output power is relative to the selected maximum power output, so that the selected maximum output power is different in each usage state. The output of the air conditioner can be accurately identified, and the visibility and usability can be greatly improved.
