In step 32), the room temperature detected by the temperature detector (9) is input, and in the second step (33), the room temperature is compared with the set temperature, and if the room temperature is lower than the set temperature, the process proceeds to step (34), where it is output. The compressor (11) is turned on via the circuit (8).

If it is high, the process proceeds to step (35), where the compressor (11) is similarly turned off via the output circuit (8).

Next, in step (36) it is determined whether there is an input from the switch (1), and if there is an input, in step (37) "
It is determined whether the "When it is hot" switch (2) or the "When it is cold" switch (3) is pressed, and if it is determined that the "When it is hot" switch (2) is pressed, the process goes to step (38).

The above description has been made regarding the case of heating operation, but in the case of cooling operation, the ON and OFF commands for the compressor (11) may be reversed.

[Problem to be solved by the invention]

Conventional air conditioner control devices are configured as described above, so when air conditioning a room, the main control is the room temperature, and humidity is not controlled and left to its own devices. In this case, when the humidity is high and the user feels hot and humid even after reaching the set temperature, the user presses the "When it's hot" switch to input the "When it's hot" switch to lower the set temperature and operate the compressor. It was used in

For this reason, when the humidity is high, it is healthier to lower the humidity and raise the temperature rather than lowering the temperature for the same level of comfort, and is especially preferred by women and the elderly.

In this way, it is impossible to input the user's sense of humidity and heat, which is the feeling of feeling hot and humid, and it is not possible to freely switch between cooling and dry operation according to the user's sense of feeling while checking the operating mode status, which causes the room temperature to rise more than necessary. Use it at low temperature and slightly chilled.
The problem was that it was not good for health.

This invention was made to solve the above-mentioned problems, and it directly expresses the user's sense of heat and humidity.
Automatically selects an operation mode such as cooling dry operation according to the expression, and while confirming the selected operation mode, changes the temperature and humidity and adjusts the set humidity to lower the temperature and avoid cooling too much. The aim is to obtain an air conditioner that creates a comfortable and healthy environment.

The present invention is provided with an operation mode selection means for selecting an operation mode and an operation mode display means.

[Effect]

In the air conditioner control device according to the present invention, two set temperature adjustment means and a set humidity adjustment means are detected by a temperature detector and a humidity detector based on inputs from the temperature expression means and the humidity and heat expression means. Based on the indoor humidity and indoor humidity, the desired temperature,
The humidity is changed to humidity, and the operation mode display means is visually checked using the heat and humidity expression means to confirm the changed operation mode. [Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st

Based on the desired humidity interval, change to a lower humidity.

(21) is an operation mode selection means for selecting an operation mode of cooling or dry operation using the temperature expression means (19) and the moist heat expression means (20), and when there is a switch input of the temperature expression means (16), Select cooling and use the moist heat expression method (1
When the switch 7) is input, dry operation is selected. Further, even when switch input is made alternately between the heat expressing means (16) and the humidity expressing means (17), it is possible to freely switch between cooling and drying.

Next, the operation will be explained with reference to the operation flowchart of the II control shown in FIG.

First, the operation switch (12) is turned ONL to start the cooling operation, and in step (30), the cooling operation is displayed. The steps from step (31) to step (42) are the same as the conventional flow unless the "steaming" switch is turned on in step (42), so the explanation will be omitted.

In step (42), turn on the “steaming” switch (18)
and tI] and proceed to step (43). Step (4
Dry operation is selected in step 3), and dry operation is displayed in step (44). In step (45), the humidity detector (+
5), the humidity is detected, and in step (46), the set humidity is calculated by increasing or decreasing the detected humidity by a desired humidity interval.

For example, the value obtained by lowering the detected humidity by 20% (however,
humidity of 60% or higher) is set as the set humidity. This set humidity may be a fixed value or a lower limit value.

Next, in step (47), it is determined whether the detected humidity is lower than the set humidity, and the process continues in step (48) until it is determined that the detected humidity is lower than the set humidity.
The compressor (11) is turned on.

When the detected humidity becomes lower than the set humidity in step (47), the process proceeds to step (49), and the compressor (11) is turned off. If the switch (1) is input again while the compressor (11) is ON or OFF, that is, during dry operation, it is determined in step (50) that there is a switch input, and the process returns to step (42), where the thermal expression means is activated. If it is determined that one of the +6 "hot" and "cold" switches (2) and (3) has been manually operated, cooling operation is selected in step (37), and cooling operation is displayed in step (38). Then, the process proceeds from step (39) to step (41) and returns to cooling operation.

On the other hand, when the "steaming" switch is turned on and the %I is turned on in step (42), dry operation is continued and the set temperature or set humidity is checked again according to the manual power of each switch.

In this way, the operation mode can be displayed corresponding to each switch of the temperature expression means (16) and the moist heat expression means (17), and the operation mode can be freely changed based on the user's senses while checking the operation mode display. By changing the air conditioner, comfortable air conditioning can be achieved.
