Hereinafter, the memory card discrimination method of the air conditioner according to the present invention will be described in more detail with reference to FIG.

5 is a flowchart illustrating a method of determining a memory card according to the present invention.

As shown in FIG. 5, the method for determining a memory card according to the present invention includes inserting a memory card 120 into one of a plurality of memory slots 130 (S1) and the memory slot 130. Applying a current to the memory card 120 to confirm whether the memory card 120 is normally inserted (S2), and the controller 80 communicates with the memory card 120 to check the type of the memory card 120 inserted. A step S3 and a step S4 of lighting an LED corresponding to the type of the memory card 120 inserted in the display section 140 of FIG. 2.

In the memory card checking step (S2), whether the memory card 120 is normally inserted through the current applied from the controller 80 is transferred to the memory card 120 through the memory slot 130. When the controller 80 determines that the memory card 120 is not normally inserted or recognized, the display unit 140 displays an LED related thereto.

The step S2 of checking the type of the memory card 120 inserted by the controller 80 will be described in more detail with reference to FIG. 6.

6 is a block diagram illustrating a circuit of a controller and a memory card of the air conditioner according to the present invention, and FIG. 7 is a block diagram illustrating a memory card verification process of the air conditioner according to the present invention.

In the present embodiment, a multimedia card (hereinafter referred to as an "MMC card") of the memory card 120 will be described as an example.

First, the memory card interface 89 of the controller 80 is connected to the memory slot 130 to form a circuit, and the controller 80 has a plurality of ports for communicating with the MMC card 122. The current is applied to any one of the ports for communicating with the MMC card 122 to confirm the response by checking the response of the memory card 120 is inserted.

Thus, when a user inserts the MMC card 122 into the memory slot 130, the controller 80 applies a reset command 122a of 0 and 1 to a command port of the MMC card 122. In addition, the MMC card 122 transmits a response signal (Response, 122b) to the control unit 80 in response to the reset command (122a), the control unit 80 through the response signal (122b) It can be seen that the MMC card 122 is normally inserted. (S2)

Here, the memory card 120 inserted into each of the memory slots 130 can check whether the memory card 120 is individually inserted through the above method, and the control unit transfers from each slot of the memory slot 130. The response signal may be checked to determine whether one memory card or a plurality of memory cards are inserted.

8 is a block diagram showing another method of confirming the memory card of the air conditioner according to the present invention.

First, the controller 80 is provided with a ground (hereinafter referred to as "GND") 81, a command port 82, ports 1, 2 (83) 84, and the like, and the MMC card of the memory card 120. Ports 122 corresponding to each port of the controller are formed at 122.

The GNDs 81 are connected to each other by the connection of electrodes when the memory cards 122 and 124 are inserted, and the first and second ports 83 and 84 are the memory cards 122 and 124. When is not inserted, it is a pull-up state in which a constant voltage is maintained (Fig. 8A).

When the user inserts the memory card (MMC, SD) into the memory slot 130, the GND 81 and the ports 1, 2 (83) 84 are connected to the ports 1, 2 (83) ( 84 is lowered and the controller 80 checks the voltages of the ports 1, 2 (83, 84) to determine whether the memory cards 122, 124 are inserted into the memory slot 130. (S2), it is possible to check what kind of memory card 120 is inserted into the memory slot 130. (S3)

On the other hand, as shown in FIG. 8, a plurality of memory cards 122 and 124 is inserted into the memory slot 130, and the controller 80 controls the command port 82. Through the reset command 82a is applied.

Thus, the memory card 130 inserted into the memory slot 130 transmits response signals 82b and 82c to the respective ports 83 and 84 with respect to the reset command 82a, and the controller controls the respective ports. The types of the memory card 130 can be confirmed by detecting the response signals 82b and 82c at (83) and (84).

Here, although the ports 1, 2 (83) 84 are connected to the GND 81 and the voltage is lowered below a predetermined value, the response signal 82b is applied to the ports 1,2 (83) 84. If 82c is not received, the controller 80 lights an LED for reinserting a memory card in which the response signals 82b and 82c have not been received to the display unit 140 and transmits the LED to the user. S4)

In the air conditioner according to the present invention, a display unit for displaying indoor temperature, desired temperature, humidity, air volume, photo, avatar, date, schedule, and the like is installed, and a memory card is inserted into a memory card to directly transmit data to the display unit. The slot is installed to easily input data desired by the user to the air conditioner.

In addition, the air conditioner according to the present invention has the effect of simplifying the appearance of the air conditioner by minimizing the memory slot is exposed to the user is located on the rear side of the front panel.

In addition, the air conditioner according to the present invention has an effect that the display window of the display unit is configured as a flat display device to transmit various types of data such as room temperature, set temperature, humidity, air volume, photo, avatar, date, schedule, etc. to the user. have.

In addition, the air conditioner according to the present invention has the effect of separately determining the type and insertion state of the memory card inserted into the memory slot is installed separately to display the type of the memory card inserted into the display unit.

In addition, the memory card check method of the air conditioner according to the present invention by applying a predetermined current to the memory slot periodically to check the inserted memory card not only to check the inserted memory card faster but also whether the memory card is inserted Is displayed on the display unit, the user can easily confirm the insertion of the memory card.

In addition, the memory card check method of the air conditioner according to the present invention has the effect of easily confirming the type of the inserted memory card by checking the electrode voltage of the controller connected to the inserted memory card.
