Hereinafter will be described the operation and effect of the air conditioner according to an embodiment of the present invention configured as described above.

In FIG. 2, S denotes a step.

First, as an initial condition for explaining the operation, a DC voltage is supplied from the first power supply means 10 to the first control means 6, and from the second power supply means 36, the second control means. Assume that 28 is supplied with a DC voltage.

First, it is assumed that a user selects a first frequency in the first frequency selecting means 26 and a first frequency in the second frequency selecting means 34. The frequency selection signal is then output from the first frequency selection means 26 to the first control means 6. Next, a frequency selection signal is output from the first control means 6 to the frequency selection circuit 20. The high frequency of the first frequency is then output from the frequency selection circuit 20 to the conversion / transmission circuit 22. Next, a frequency selection signal is output from the second frequency selecting means 34 to the second control means 28. Then, the second control means 28 recognizes only the signal having the first frequency among the signals input from the receiving means 30 to the second control means 28 as a control signal for air conditioning.

Next, in step S1, the user inputs an operation command to the key input means 8. The operation command is then input from the key input means 8 to the first control means 6. The first control means 6 then inputs an operation command of the user.

The first control means 6 then reads data corresponding to the user's operation command from the memory of the first control means 6 in order to send the user's operation command to the indoor unit 2.

Next, a control signal corresponding to a user's operation command is output from the first control means 6 to the conversion / transmission circuit 22. Then, the control signal having the first frequency is transmitted from the conversion / transmission circuit 22 to the indoor unit 2.

Next, in step S2, the reception means 30 of the indoor unit 2 receives the control signal transmitted from the conversion / transmission circuit 22 of the remote controller 4. Next, a control signal is output from the receiving means 30 of the indoor unit 2 to the second control means 28.

Next, a control signal is output from the second control means 28 to the load driving means 42 in step S3. Then, the compressor and the indoor fan motor are driven by operating the load driving means 42. The air in the room is then harmonized.

On the other hand, when the user transmits a control signal of the first frequency from the remote controller 4 to the indoor unit 2 as described above, other household appliances around the indoor unit 2, for example, when the television is turned on The user selects the second frequency by the first frequency selecting means 26.

The user then selects a second frequency in the second frequency selecting means 34. Subsequently, when the user transmits a control signal from the remote controller 4 to the indoor unit 2 from step S1 to step S2 as described above, the user receives the control signal transmitted from the remote controller 4 to the indoor unit 2. Accordingly, the compressor and the indoor fan of the indoor unit 2 are operated.

On the other hand, during the manufacturing process of the indoor unit (2) and the remote controller (4) by dividing the indoor unit (2) of a plurality of models for each group to the indoor unit (2) of a plurality of models of each group of one of the first to fourth frequency Release the product by assigning a common. Then, since one remote controller 4 is made to be commonly used for the indoor units 2 of multiple models in a group, the user may use the indoor unit 2 that he or she is using at the product sales floor even if the remote controller 4 is lost. You can easily purchase a remote controller (4) for.

According to the air conditioner according to the present invention as described above, by configuring a remote controller and the indoor unit to operate a plurality of indoor units by one type of remote controller, even if the user of the product loses the remote controller, a new remote at the product sales floor. There is a very good effect that the controller can be easily purchased.

In addition, by configuring a frequency selection switch to the user to select one of the frequencies of the first to fourth frequency in the remote controller, if the frequency of confusion with the household appliances around the indoor unit during use of the remote controller, the user changes the frequency It has a very good effect of preventing frequency crosstalk.

In addition, by applying a remote controller having a single frequency to a plurality of indoor units has a very excellent effect that can simplify the procedure of testing the remote controller in the manufacturing process of the product.
