An outdoor suction temperature measuring means for measuring the temperature, a set temperature storing means for storing the set temperature inside the room, a time measuring means for measuring an elapsed time from the start of operation, and a time storing means for storing a predetermined time in advance,
A time comparing means for comparing the measured time of the time measuring means with a fixed time determined by the time storing means, an indoor suction temperature measured by the indoor suction temperature measuring means, and an outdoor suction temperature measuring means measured by the outdoor suction temperature measuring means. Operation control of the air conditioner having operation mode determination means for determining cooling or heating in automatic operation in response to the outdoor intake temperature, the set temperature stored by the set temperature storage means, and the determination result of the time comparison means. It is equipped with a device.

When the judgment result of the operation mode judging means according to claim 1 is changed from cooling to heating and from heating to cooling, a predetermined conversion amount corresponding to each mode switching is output and the operation switching conversion amount is output. Output means,
An indoor suction temperature measured by the indoor suction temperature measuring means according to claim 1, an outdoor suction temperature measured by the outdoor suction temperature measuring means according to claim 1, and a setting stored by the set temperature storage means according to claim 1. An operation control device for an air conditioner, comprising: a temperature, a judgment result of the time comparison means according to claim 1 and an output of the operation switching conversion amount output means, and operation mode judging means for judging cooling or heating in automatic operation. It is equipped with.

[0008]

The operation of the above technical means is as follows.

According to the present invention, the above-mentioned configuration makes it possible to determine the operation mode in consideration of the set temperature during the automatic operation. Therefore, it is possible to determine the operation in the operation mode according to the temperature set by the user. is there.

Further, by storing the history of the operation modes and providing a difference in the boundary value of the mode judgment when switching between the cooling operation and the heating operation, it is possible to control so that the switching between the cooling operation and the heating operation does not occur frequently. It will be.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to the drawings. 1 is a schematic block diagram of an air conditioner according to a first embodiment of the present invention. In the figure, 1 is an indoor suction temperature measuring means for measuring the suction temperature of the indoor unit, 2 is an outdoor suction temperature measuring means for measuring the suction temperature of the outdoor unit, and 3 is a set temperature storage for storing the set temperature of the room. Means 4, a time measuring means for measuring an elapsed time from the start of operation, 5: a time storing means for storing a fixed time in advance, 6: a measured time of the time measuring means 4 and a fixed time determined by the time storing means 5. Time comparison means for comparing time, 7 is an indoor suction temperature measured by the indoor suction temperature measuring means, an outdoor suction temperature measured by the outdoor suction temperature measuring means, and a set temperature stored by the set temperature storage means. And an operation mode judging means for judging cooling or heating in automatic operation in response to the judgment result of the time comparing means.

The operation of the above arrangement will be described below. When the automatic operation is started in the air conditioner, the indoor suction temperature measuring means 1 measures the indoor suction temperature and the outdoor suction temperature measuring means 2 measures the outdoor suction temperature. The set temperature in the room set by the user is stored in the set temperature storage means. When the automatic operation is started, the time measuring means 4 measures the operating time, and the time comparing means determines whether or not the set operating time stored in the time storing means 5 has been reached. Then, the operation mode determination means is based on the indoor suction temperature measured by the indoor suction temperature measurement means 1, the outdoor suction temperature measured by the outdoor suction temperature measurement means 2 and the set temperature stored by the set temperature storage means 3. In 7, it is possible to judge the cooling or the heating in the automatic operation at every time stored in the time storage means 5.

Next, a second embodiment of the present invention will be described. FIG. 2 is a schematic block diagram of an air conditioner according to the second embodiment of the present invention. In the figure, reference numeral 8 denotes an operation switching conversion amount output means for outputting a predetermined conversion amount corresponding to each mode switching when the judgment result of the operation mode judging means is changed from cooling to heating and from heating to cooling. .

The operation of the above arrangement will be described below. The conversion value output from the operation switching conversion amount output means when the operation mode determined by the operation mode determination means 7 according to claim 1 is switched after the time preset in the time storage means 5, and the indoor suction Based on the indoor suction temperature measured by the temperature measurement means 1 and the outdoor suction temperature measured by the outdoor suction temperature measurement means 2 and the set temperature stored by the set temperature storage means 3, the operation mode determination means 7 automatically operates. It is possible to make a judgment of cooling or heating in.

[0015]

As is apparent from the above-described embodiment, the present invention can determine the driving mode in consideration of the set temperature during automatic driving, so that the driving mode can be judged according to the temperature set by the user. Is possible.

Further, by storing the history of the operation modes and providing a difference in the boundary value of the mode judgment when switching between the cooling operation and the heating operation, it is possible to control so that the switching between the cooling operation and the heating operation does not occur frequently. It will be.
