BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner control device for an air conditioner, which agitates indoor air by directing the blowing direction of warm air toward the underfloor when the indoor temperature approaches or exceeds a certain temperature. .

[0002]

2. Description of the Related Art On the basis of temperature data from a room temperature sensor provided in an indoor unit of an air conditioner, for example, during heating operation, while the detected temperature data is lower than the indoor set temperature set by a remote controller or the like, the heating intensity is high. It is common to continue the operation and drop it to a weak operation when it reaches the set temperature, or stop the operation, and for the purpose of raising the indoor temperature evenly, the air outlet that blows out the heat-exchanged air. Is equipped with a flap (wind direction changing plate) that swings at a predetermined angle to change the wind direction and circulates the indoor air.

Further, since hot air tends to go upward, it is necessary to blow out warm air downward during heating than during cooling, and two flaps whose angles change independently are provided at the hot air outlet. , The angle of these two flaps is changed when heating, and the twin flap mechanism that sets different angles so that the warm air is directed to the diagonal floor surface as in the case of cooling, and a dedicated air blower in front of the hot air outlet There are products that are characterized for heating, such as a twin flow mechanism that blows indoor air using a blower to prevent warm air from rising due to the flow of indoor air.

[0004]

As described above, during heating operation, high-temperature air tends to have a low density and rise, and the indoor temperature tends to be high in the upper part and low in the lower part. It is desired to circulate downward only to eliminate the temperature difference between the upper and lower sides even at a position away from the air conditioner. And as a countermeasure against this, two blowers or two flaps are provided to create a blower flow path downward, but this is for cooling air on the diagonal front floor with people for the purpose of air circulation. Like the above, it is a device for delivering warm air, which is not a good method because it leads to cost increase.

SUMMARY OF THE INVENTION The present invention solves the above problems by using two blowers or two flaps,
The aim is to make the room temperature uniform during heating. That is, the air intake port 2 is provided on the front surface of the indoor unit body 1 attached to the upper part of the room, and the air outlet port 3 is provided below the air intake port 2, and the air intake port 2 is provided inside the indoor unit body 1. And a blower 5 provided in the vicinity of the heat exchanger 4, a room temperature sensor 6 located in the vicinity of the air suction port 2 and the heat exchanger 4, and the air outlet port 3 In an air conditioner having a flap 7 capable of varying the air flow direction, when the temperature data of the room temperature sensor 6 becomes close to the temperature data set by the room temperature setting unit 8 during heating operation, the angle of the flap 7 is set to the floor direction. The structure is an air conditioner control structure for an air conditioner that is operated toward

Further, when the temperature data of the room temperature sensor 6 becomes the temperature data set by the room temperature setting unit 8, the air conditioner is set to the weak operation, the flap 7 is switched to the floor direction, and the weak operation time is set by the timer 9. By controlling for a certain period of time, the stirring operation is continuously performed for a certain period of time to eliminate the unevenness of the room temperature.

[0007]

The air conditioner according to the present invention sucks indoor air into the indoor unit body 1 of the air conditioner by the operation of the blower 5, conditioned by the heat exchanger 4, and then cooled indoors through the air outlet 3. The air is emitted as warm air, and operation is controlled by the room temperature sensor 6 to a room temperature to be controlled. In the present invention, when the room temperature sensor 6 approaches the preset room temperature during the heating operation, the angle of the flap 7 is forcibly directed toward the floor to guide the floor directly below the air conditioner. The air in the room is agitated from the top to the bottom of the circulation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure will be described below with reference to the drawings showing an embodiment of the present invention. Reference numeral 1 denotes an indoor unit body mounted above an indoor side wall surface of an air conditioner, which is a refrigeration cycle configured to communicate with an unillustrated outdoor unit. It has a built-in heat exchanger 4.

Reference numeral 2 is an air inlet for indoor air provided in the upper front portion of the indoor unit body 1, 3 is an air outlet provided under the air inlet 2, and 4 is the indoor unit body 1
A heat exchanger provided inside the air suction port 2 so as to face the air suction port 2,
A blower 5 is provided in the indoor unit main body 1 in the vicinity of the heat exchanger 4. By changing the normal circulation path of the refrigerant in the refrigeration cycle, the heat exchanger 4 becomes hot or cold. To become. Therefore, if the indoor air is sucked from the air suction port 2 by the blower 5 and passed through the heat exchanger 4, warm air or cold air is produced and is blown out into the room from the air blowing port 3.

Reference numeral 6 denotes a room temperature sensor for detecting the temperature (room temperature) of the indoor air to be sucked, which is an air intake port 2 and a heat exchanger 4.
Although it is provided at a proper place between the heat exchanger 4 and the heat exchanger 4, it is preferable that the heat exchanger 4 be fixed to the air suction port 2 side. 7 is a flap that is provided in the middle of the air outlet 3 to change the blowing direction of warm air and cold air, and swings at an appropriate angle by a motor 7a
Air circulation and agitation are performed to make the temperature of the indoor air uniform.

In particular, in the present invention, as shown in the flow chart of FIG. 3, when the room temperature setting unit 8 is instructed in advance about the temperature to be controlled and the heating operation is performed, the temperature data of the room temperature sensor 6 read by the comparison operation circuit 10 is obtained. A comparison is made with the temperature set in the room temperature setting unit 8. The comparison operation circuit 10 determines whether the room temperature detected by the room temperature sensor 6 and the set temperature of the room temperature setting unit 8 are the same or higher, and when the room temperature is near the set temperature,
Send a signal to switch the angle of the flap 7 to the floor,
Direct the blowing air toward the floor, direct the warm air toward the lower part of the room,
The function is to prevent high temperature layers from forming near the ceiling.

Then, the normal heating operation is resumed with the flap 7 fixed at the downward angle, and the room temperature reading operation is continued again. When the cold air on the floor surface rises due to the warm air directed toward the floor surface and the room temperature sensor 6 detects a low temperature, the heating operation in which the normal flap 7 is swung is performed. At this time, since there is a time lag until the cold air on the floor surface rises and the room temperature sensor 6 detects a low temperature, the flap 7 may be turned downward and the timer 9 may start counting to delay the start of the normal heating operation. , The time for fixing the flap 7 downward is the same, and there is no discomfort.

The temperature at which the flap 7 is directed downward is
The temperature may be matched with the temperature at which the heating operation is switched to the weak operation, and only one comparison calculation circuit may be used for simplification. In this case, the flap 7 is fixed downward when the heating operation is switched to the weak operation.

If the manufacturing cost is not a particular problem,
By providing two comparison calculation circuits and switching the heating capacity and fixing the flap 7 downwardly at different temperatures, the range of applications will be wider, and the room temperature will rise and the temperature of the ceiling will rise during weak heating operation. When the temperature becomes low, the flap 7 is turned downward to perform stirring operation, or the flap 7 is turned downward during strong air blowing before the heating operation is switched to weak operation, allowing high-temperature air to reach the floor quickly and setting the room temperature. The usage can be selected such that it is harder to raise the temperature. Further, the combined use with the conventional twin flow mechanism or twin flap mechanism is also effective for uniforming the room temperature.

Reference numeral 2a denotes a front plate which constitutes a front portion of the indoor unit body 1, and the air suction port 2 is resin-molded on the front plate 2a in a lattice shape or the like. 2b is the indoor unit body 1
It is a rear plate that constitutes the rear part of the rear. Reference numeral 11 designates a wind tunnel plate that also serves as a partition plate that guides the wind of the blower 5 toward the air outlet 3 in the indoor unit body 1, and 12 is a drain receiver provided in the lower portion of the heat exchanger 4, which is present indoors during cooling operation The moisture is drained by the heat exchanger 4 and flows down to be discharged outside the room.

EFFECTS OF THE INVENTION Since the present invention has the above-described structure and operation, in a heating operation in which normal warm air is circulated, in order to prevent warm air having a low density from staying on the ceiling, it is forcibly forced. Warm air is blown toward the floor to stir the indoor air,
By increasing the temperature of the space below the air conditioner, the temperature near the top of the sky did not rise too much, and efficient heating operation became possible.

Further, the command for changing the flap 7 downward may also be used as a comparison arithmetic circuit for switching the heating capacity by comparing the read data of the room temperature sensor 6 with the set temperature of the room temperature setting section 8 to be controlled. For example, the structure is simple and the stirring operation of indoor air can be performed at low cost.
