Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control device for an air conditioner that performs a preparatory operation according to an air conditioning load so that a set temperature is reached at a set time.

Conventional technology In general, the amount of heat that must be provided per unit time by air conditioning to maintain the indoor air in the required state is called heating load, and the amount of heat that must be removed is called cooling load, and air conditioning load includes the necessary amount of humidity adjustment. That's what it means. The approximate value of this air conditioning load can be determined by the difference between the room temperature and the temperature set value.

Therefore, even if the air conditioner starts operating, it does not reach the desired room temperature immediately, so an air conditioner that performs a preparatory operation in advance has been proposed.

Hereinafter, a control example of the conventionally proposed air conditioner control device described above will be described with reference to the drawings.

FIG. 4 shows an outline of a preparatory operation control flowchart 1 during heating of a conventionally proposed control device for an air conditioner. In step 201, when one hour before the set time to start air conditioning, the process moves to step 202, and air blowing operation is performed for 20 seconds.

Next, in step 203, the outside air temperature and the suction temperature are detected,
Examine the relationship. Here, as shown in FIG. 5, if it is in area A, step 204; if it is in area B, step 206.
, C area, the process advances to step 206. Step 20
In step 4, the preparatory operation is performed for 30 minutes, in step 205, the preparatory operation is performed for 20 minutes, and in step 206, the 1°1'j operation is continued for 1Q minutes, and the preparatory operation mode is ended.

However, if the set temperature is high, step 204 will take a maximum of 60 minutes, and step 205 will take a maximum of 50 minutes.
A preparatory run of up to 40 minutes is carried out in step 206.

Problems to be Solved by the Invention However, in the conventional configuration, the preparatory operation was ended by a timer regardless of the room temperature after the preparatory operation. Furthermore, even if the room temperature drops after the preparatory operation is completed, the device is left unattended until the set time arrives. Therefore, there has been a problem in that it is difficult to provide a comfortable environment at the set time.

In order to solve the above problems, the present invention aims to provide a control device for an air conditioner that can efficiently reach a comfortable room temperature close to a set temperature at a set time.

Means for Solving the Problems In order to achieve the above object, the air conditioner control device of the present invention includes a room temperature detector for detecting the room temperature, a temperature setting device for setting the air conditioning temperature, and an air conditioning start time. A reservation setting device for setting a reservation, an outside temperature detector for detecting outside temperature, and an operation state storage means for storing outside temperature and operation time are installed in 17f.
This is an excellent configuration.

Effect: With the above-described configuration, the present invention stores the preparatory operation time until reaching the air conditioning temperature set by the temperature setting device and the outside temperature detected by the outside temperature detector in the operation state storage means, and The start time of the preparatory operation is controlled according to the temperature, and the air conditioning set temperature is reached at the air conditioning start time set by the reservation setting device in the minimum operating time.

It is comprised of a temperature detector 7 and a driving state storage means 8 that stores the outside temperature and driving time.

Next, the operation of the air conditioner control device configured as described above will be explained using the flowchart in FIG. 2 and the graph of the change in room temperature over time in FIG. 3. When the air conditioning start time is set with the reservation setting device 6 and the air conditioning temperature is set with the temperature setting device 5, the system is operated according to the procedure of the flowchart shown in FIG.

In step 101, the outside temperature detector 7 detects the outside temperature. Next, in step 102, it is checked whether the relationship between the outside temperature detected in step 101 and the time required to reach the air conditioning temperature set by the temperature setting device 5 is stored in the operating state storage means 8, and the corresponding If there is outside temperature data, the process advances to step 103; otherwise, the process advances to step 104. In step 103, the process waits until the preparatory operation start time determined from the arrival time data obtained in step 102 and the air conditioning start time set by the reservation setting device 6, and when the preparatory operation start time arrives, step 10561 is performed.
