Description

[Detailed Description of the Invention] (a) Field of the Invention The present invention relates to an air conditioner capable of cooling and heating operations, and particularly relates to a simple display device that allows the room temperature to be clearly recognized.

(b) Prior art Figure 1 is a front view of a display device according to the prior art.
Display device from a group of light-emitting bodies 17' to 23' for room temperature display, a cooling scale 6', a heating scale 7', a light-emitting body 13' for cooling display, a light-emitting body 15' for heating display, and a cooling/heating changeover switch 3'. was configured. In addition, FIG. 2 is an electrical circuit diagram in FIG. 1, and 24'
The light emitting bodies 17' to 23' are detected by the room temperature sensor 25'.
In the display device shown in FIG. 1, the display value by the temperature sensing mechanism 24' is different between the cooling scale 6' and the heating scale 7'. Luminous body for heating display 1
By lighting 5', the cooling scale 6' and the heating scale 7' were distinguished, and the displayed value of the room temperature by the temperature sensing mechanism 24' was recognized.

(c) Problems with the prior art In this prior art, it was necessary to select and recognize the cooling scale 6' and the heating scale 7' by checking the lighting display by both the light emitters 13' and 15'. There were times when I had to read it.

(d) Prior art Other than the above, conventional technology includes a digital display of room temperature using numbers, and as shown in Figure 3, a cooling scale 6'' and a heating scale 7'' are partially overlapped and marked continuously, and each scale is A group of light emitters 27 was provided facing each other to display the room temperature.

(e) Problems with the prior art The digital display of the prior art has a problem in that the structure is complicated and expensive. Further, in the prior art shown in FIG. 3, since the temperature ranges for cooling and heating are different, the number of light emitter groups 27 increases and the cost becomes high.

(f) Purpose of the invention The purpose of the invention is to provide a display device that allows the scale to be clearly recognized with a minimum number of light emitters.

(g) Key points of the invention This invention uses a display device for an air conditioner in which cooling or heating operation can be selected by operating an operation switch, which uses a plurality of light emitters that are arranged in a line and light up based on the room temperature. , a display board facing each of these light emitters on which a cooling scale and a heating scale are attached in a linear manner; light is emitted from the rear side onto both scales in different colors; By providing a scale light-emitting body that emits light in the color of , and a control mechanism that lights up one of these scale light-emitting bodies in conjunction with the operation of the operation changeover switch, the display can be adjusted according to cooling operation or heating operation. The cooling scale or the heating scale can be displayed in different colors from the back side, and the room temperature can be displayed simultaneously using a plurality of light emitters.

(H) Embodiment of the invention An embodiment of the invention will be explained based on FIGS. 4 to 8. FIG. 4 is a perspective view of an air conditioner using the device of the invention, and 1 is a housing; 2 is a display device;
Reference numeral 3 denotes an operation changeover switch for switching between "fully automatic,""cooling," and "heating."As shown in FIGS. 5 to 7, the display device 2 is constructed as follows. That is, 4 is a transparent or semi-transparent display board with a light-blocking part 5 printed on the front side, and a cooling scale 6, a heating scale 7, characters 8 for "cooling", characters 9 for "heating", and ``fully automatic''. ” character 10 etc. are provided. 1
1 seals the light and efficiently displays scales 6, 7 and letters 8,
The display board 4 has a curved surface that emits light from the back side of 9 and 10.
12 and 13 are green light emitters that light up during cooling operation, 14 and 15 are red light emitters that light up during heating operation, 16 is a light emitter that lights up during fully automatic operation, and 17 to 23 are light emitters that light up during fully automatic operation. It is a light emitter that lights up depending on the room temperature. FIG. 8 is an electrical circuit diagram of an embodiment of the present invention, and 24 is a temperature sensing mechanism having a room temperature sensor 25 for controlling the lighting of the light emitters 17 to 23. 26 is a light emitter 12, 13, 1 depending on the position of the changeover switch 3 and the input from the room temperature sensor 25.
This is a control mechanism that controls the lighting of lights 4, 15, and 16.

Since the embodiment of the present invention is constructed as described above, when the changeover switch 3 is on the "fully automatic" side, the control mechanism 26 lights up the light emitter 16 to display "fully automatic", and at the same time, Based on the temperature sensed by the room temperature sensor 25, it is determined whether to perform cooling operation or heating operation, and the light emitters 12 and 13 or the light emitters 14 and 15 are turned on to display the cooling scale 6 and the character ``cooling'' 8 or the heating scale 7. The character 9 of "heating" is displayed. Therefore, even if the room temperature is displayed by the temperature sensing mechanism 24, the scale can be easily read. Next, when the changeover switch 3 is on the "cooling" side, the control mechanism 26 turns on the light emitters 12 and 13 to display the cooling scale 6 and the character "cooling" 8 in green. Also, switch 3 is set to "heating"
If the control mechanism 26 is located on the side, the control mechanism 26
5 is turned on to display the heating scale 7 and the character 9 of "Heating" in red.

Incidentally, FIG. 9 is a front view of another embodiment using the present invention, and the same parts are given the same reference numerals and the explanation thereof is omitted.

(li) Effects of the invention The present invention arranges a plurality of light emitters in a line that lights up based on the room temperature, and adds a cooling scale and a heating scale in a line opposite to the plurality of light emitters. The control mechanism selectively illuminates the scales corresponding to cooling operation and heating operation in different colors from the back side, so the color of the luminescence display on the scale changes and the user can see when the air conditioner is in cooling operation. It is possible to clearly confirm whether the heating operation is in progress or heating operation by the difference in color.
At the same time, you can confirm which scale to read by lighting up the scale illuminant, making it easy to read the room temperature value that corresponds to the correct scale. Also, since the scale is displayed with luminescent light, the room temperature can be easily checked even in dark places by displaying the room temperature with a light-emitting body.
