Description

[Detailed Description of the Invention] The present invention relates to a device for displaying temperature, etc. of an air conditioner, and more specifically, the present invention relates to a device for displaying temperature, etc. of an air conditioner.
The present invention also relates to a temperature display device that displays set temperatures and the like in a continuous graph.

Conventionally, as a display device for temperature, etc. in an air conditioner, it is common to directly use a display element consisting of a plurality of light emitting diodes (hereinafter simply referred to as LED) on a display panel. Displays were made by turning on, blinking, or turning off elements based on changes in temperature or the like.

This conventional device uses one display element for a certain temperature, such as 20 degrees or 21 degrees, so the number of display elements for the entire required temperature range is not that large, and therefore LED The arrangement pattern of display elements such as
The drawback was that it was difficult to recognize visually. However, in order to create a display pattern that is easy to visually recognize, a large number of LEDs are required, and as a result, the area occupied by the display device becomes large, and there are many problems such as an increase in cost.

Therefore, the purpose of the present invention is to solve the problems with conventional display devices of this type, and to provide an air conditioner that is easy to visually recognize by displaying the indoor temperature and other conditions in a continuous linear manner in the form of a graph. An object of the present invention is to provide a temperature, etc. display device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the temperature display device for an air conditioner according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a circuit diagram of an electric block in one embodiment of the present invention, in which a thermistor element 10 that detects the temperature of the air in a room to be air-conditioned is a one-chip microcomputer LSI with an analog-to-digital converter ( (hereinafter simply referred to as LSI) 11 as its input. One output of this LSI 11 is electrically connected to a display buffer 12, and the display buffer 12 is connected to a plurality of LSIs 13 to 19 that turn on, blink, or turn off depending on the temperature state.
electrically connected to.

Also, the other output of the LSI 11 is a buffer 2.
0 to a relay coil 21 that controls the compressor, fan motor, etc. of the air conditioner.

By the way, the aforementioned LEDs 13 to 19 each include optical fiber bundles 13a to 1 in which a plurality of LEDs are combined into one bundle.
One end of 9b is connected. In order to explain this connection state in more detail, refer to FIG. 2, in which one LED 13 and one end of one optical fiber bundle 13b connected to it are representatively shown enlarged. . As is clear from this figure, the bundle 13b consisting of a plurality of optical fibers has one end of each optical fiber connected to the LED 13 with a connector 13a.
is combined with Therefore, this one LED1
3 emits light, this light is transmitted from one end of the optical fiber bundle 13b through each of the plurality of optical fibers that make up the bundle, reaches the other end of each optical fiber in the bundle, and displays a light emission display on the end face. I will do it. Therefore, the other end of the optical fiber can also be referred to as the light emitting end.

The other end of each optical fiber bundle, that is, the light emitting end, whose one end is connected to each of the LEDs 13 to 19 in this way, has its end surface displayed on the temperature display panel 22 of the control status display section of the air conditioner, as shown in FIG. It is arranged to face the front and to form a continuous linear shape in the form of a curve or a line graph.
For example, assume that each temperature (24°C to 30°C) is shared by four optical fibers (therefore, four optical fibers constitute a bundle, and one bundle, that is, four optical fibers). The fibers are all connected to one LED) and have a total of 28 light emitting ends which form a continuous curved or line graphical display pattern.

As an indication of a predetermined temperature range such as the so-called healthy cooling range for air conditioners, etc., for example, 26 ° C ~
The temperature display frame 23 of 28° C. or the plurality of optical fiber bundles corresponding to the temperature range has its luminescent color changed to a different tone from the others, thereby making this temperature range even easier to visually recognize. There is. That is, each of the four LEDs respectively coupled to a corresponding LED 15 to 17 to display each temperature from 26°C to 28°C.
The optical fiber bundles 15b to 17b are comprised of optical fibers whose color tone is different from that of the optical fibers responsible for displaying other temperatures.

According to the temperature display device for an air conditioner according to the present invention as described above, the LSI 11 has a logic that reads the temperature detection amount by the thermistor element 10 that detects the indoor air temperature and lights up the LED corresponding to the temperature. It is sent to the LED driving buffer 12 to light up the LED. Each LED is connected to four optical fibers, so when one LED is turned on, it is displayed as four consecutive points of light on the temperature display panel 22.

For example, when the LSI 11 reads an indoor air temperature of 28° C. through the thermistor element 10, the LSI 11 lights up the LED 16 corresponding to 28° C. through the buffer 12. And LED16
Through a connector 16a (not shown), each light emitting end of a bundle 16b consisting of four optical fibers with different color tones is displayed on the temperature display panel 22. Note that it is also possible to make the set temperature blink at the same time under the control of the LSI 11.

As described above, the air conditioner temperature display device of the present invention clearly shows information such as indoor temperature, set temperature, humidity, etc. to the user using a display pattern that is easy to visually recognize and a light-emitting display with different color tones. can be displayed.
