DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS.

The same components as those described in the section of the related art are denoted by the same reference numerals, and detailed description thereof will be omitted.

(Embodiment) FIG. 1 is a block diagram of a remote-control transmitter for a cooling / heating device according to an embodiment of the present invention, and FIG.
1 is an operation unit in which a plurality of translucent operation keys are arranged, and 2 is a display unit such as an LCD for displaying the operation contents of the operation unit 1. Figure 5
, An operation key 1A for turning on / off the operation of a remotely controlled air conditioner, which is often used, and an operation key 1B for switching the operation state of the air conditioner to air conditioning, dehumidification, air cleaning, etc. Operation keys 1C and 1D for temperature setting are arranged.

Reference numeral 3 denotes a control unit such as a microcomputer mounted on the wiring board 6 and connected to the operation unit 1 and the display unit 2.
The controller 3 stores remote control data for remotely controlling the air conditioner and a transmitter 4 such as an infrared light emitting diode.

Reference numeral 7 denotes an EL element connected to the control unit 3 as a light emitting element having two light emitting layers that emit warm and cool colors. The EL element 7 includes the operation unit 1 and the display unit 2. And a remote control transmitter is configured to illuminate them from behind.

FIG. 3 is a partial cross-sectional view of such an EL device. In FIG. 3, reference numeral 11 denotes a transparent insulating film such as polyethylene terephthalate. 12A and a warm-colored light-emitting layer 13 in which zinc sulfide or the like is dispersed in a synthetic resin are sequentially stacked.

Further, a light-transmitting electrode layer 12B, a cool-colored light-emitting layer 14, and a silver or carbon resin-based back electrode layer 15 are further formed on the insulating layer 1B by printing.
6 covers the EL element 7.

In the above configuration, when each operation key of the operation unit 1 is operated, the movable contact on the lower surface of each operation key comes into contact with the fixed contact on the upper surface of the wiring board 6, whereby the remote control data stored by the control unit 3 is electrically transmitted. The signal is output as a signal, and the transmission unit 4 transmits an infrared remote control signal from the electric signal.

For example, when the operation key 1B of the operation unit 1 is pressed, remote control data for switching the operation state is output from the control unit 3 as an electric signal, and the transmission unit 4 transmits an infrared remote control signal by this electric signal. This is received by the air conditioner, and the operation state is switched to cooling, heating, dehumidification, air cleaning, and the like.

At this time, for example, when the air conditioner is switched to cooling, a voltage is applied to the light transmitting electrode layer 12B and the back electrode layer 15 of the EL element 7, and the cool color light emitting layer 14 between the light emitting electrode layer 12 and blue or green is used. The operation key 1B and the display of the display unit 2 are illuminated in the cool color.

On the other hand, when the color is switched to the warm color, a voltage is applied to the light-transmitting electrode layers 12A and 12B, and the warm color luminous body layer 13 emits a warm color such as pink or orange between the layers. 1B and the display of the display unit 2 are illuminated with a warm color.

Further, when the operation mode is switched to an operation state other than cooling and heating such as dehumidification and air cleaning, a voltage is applied to the light-transmitting electrode layers 12A and 12B and the back electrode layer 15, and the cool luminescent layer 14 is also warmed. Since the light emitting layer 13 also emits light simultaneously,
The display of the operation keys 1B and the display unit 2 is illuminated with an intermediate color such as white, which is a mixture of these cool colors and warm colors.

Similarly, operation keys 1C and 1D for temperature setting
When the operation key 1C for increasing the temperature is pressed, the warm-colored luminous body layer 13 of the EL element 7 emits light. When the operation key 1D for decreasing the temperature is pressed, the cool-color emission is performed. When the body layer 14 emits light, the operation keys 1C and 1D
And the temperature display of the display unit 2 is illuminated.

As described above, according to the present embodiment, the EL that emits warm and cool colors is provided behind the operation unit 1 and the display unit 2.
A remote control transmitter / receiver for an air conditioner / heater, in which the element 7 is arranged and the EL element 7 emits a warm color light when the operation of the operation unit 1 is heating or temperature rise, and emits a cool color when the operation is cooling or temperature decrease. When the air conditioner and the temperature are set, the operation unit 1 and the display unit 2 emit warm or cool light depending on the operation contents, so that the operation and display can be easily confirmed, and the user-friendly remote control for the air conditioner can be used. A transmitter can be obtained.

When the operation of the operation unit 1 is other than cooling and heating, the EL element 7 emits light of an intermediate color, so that it is easy to confirm when setting other than cooling and heating such as dehumidification and air cleaning. It can be easy to use.

It is also assumed that the EL element 7 is formed with two light emitting layers of a cold light emitting layer 14 and a warm light emitting layer 13 which emit light of a cool color and a warm color, and the two light emitting layers are made to emit light simultaneously. By emitting a neutral color, the light emitting layer has two layers of E
Since the warm color, the cool color, and the intermediate color can be emitted by the L element 7, the remote control transmitter can be made inexpensive.

Note that the cool luminescent layer 14 and the back electrode layer 15
Further, a light-transmitting electrode layer and an intermediate color light-emitting layer are formed, and these are covered with an insulating layer 16 to constitute an EL element.
When the operation keys and the display on the display unit 2 are illuminated in an intermediate color, the present invention is also applicable to a configuration in which the intermediate color light emitting layer emits an intermediate color such as yellow or light green.

Also, the upper electrode formed on the lower surface of the upper substrate such as a flexible insulating film is opposed to the lower electrode formed on the upper surface of the lower substrate at a predetermined gap by a dot spacer formed between the upper and lower substrates. By arranging the transparent touch panel that performs a switching operation by a pressing operation on the front of the display unit 2 such as an LCD, a remote control transmitter that can perform various settings and operations on the display unit 2 can also be provided.

Furthermore, in the above description, the remote control transmitter having the simplest configuration with the least number of components has been described. However, a plurality of EL elements, light emitting diodes, etc., which emit light of different colors, are used for the operation unit 1 and the display unit 2. It may be arranged rearward to emit a warm color, a cool color, or an intermediate color by a combination of these.

[0037]

As described above, according to the present invention, it is possible to obtain an advantageous effect that a remote control transmitter for air-conditioning and heating can be obtained which is easy to operate and confirm the display and is easy to use.
