Abstract

PURPOSE:To make the temperature distribution in a room uniform by a method wherein operation of a fan is continued after the temperature difference between the room temperature and the set value becomes less than a specified value, and an air deflector stops turning when the temperature difference is the specified value or higher and is turned when it is less than the specified value. CONSTITUTION:Air in a room flows into a unit main body 1 through a suction grille 2 by sucking action of a fan 4, driven by a fan mator 5, is turned into cooled or heated air by specified heat exchanging at a heat exchanger 6 and directed toward an air outlet 8 through an air path 7. In this case, operation of the fan motor 5 is continued after the room temperature reaches the set temperature, and the motion of an air deflector 10 mounted on the air outlet 8 is stopped until the room temperature reaches the set temperature. After the room temperature reaches the set temperature, the air deflector 10 is turned by a driver 9 to make the temperature distribution in the room uniform. Or, operation of the fan motor 5 is continued after the temperature difference between the room temperature and the set temperature becomes less than a specified value, and the air deflector 10 stops turning when the temperature difference is the specified value or higher and is turned by the driver 9 when it is less than the specified value.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an air conditioner equipped with a movable wind direction changing plate.

<Conventional technology> Conventionally used electric wind direction change plate (wind direction adjustment device)
This air conditioner is configured to automatically set the recommended blow direction for both cooling and heating (horizontal direction for cooling, downward direction for heating) using this air direction change plate.

<Problems to be Solved by the Invention> However, although the above-mentioned control is used to make the temperature of the room as uniform as possible, it is still difficult to say that it is sufficient.

Furthermore, when the thermostat is off and the compressor is stopped, no measures have been taken to equalize the room temperature, and during cooling the air is blown in the same direction as when the compressor is running (for example, in the
(Refer to Publication No. 17) During heating, the wind speed was reduced to a low level and the wind direction was horizontal.

In view of the above circumstances, an object of the present invention is to provide an air conditioner that solves the above problems by automatically changing the wind direction changing plate while operating the blower after the compressor has stopped. This is what I did.

<Means for Solving the Problems> The present invention includes an air outlet for discharging air whose temperature has been adjusted by a heat exchanger into a room by operating a blower, and a wind direction changing plate rotatably supported by the air outlet. In the air conditioner, the blower continues to operate even after the indoor temperature reaches the set value, the movement of the wind direction changing plate is stopped until the indoor temperature reaches the set value, and the indoor temperature is set to the set value. A drive device is provided that rotates the wind direction changing plate after the value is reached.

Another invention is equipped with an air outlet for discharging air whose temperature has been adjusted by a heat exchanger into the room by operating a blower, and a wind direction changing plate rotatably supported by the air outlet, so as to adjust the indoor temperature and setting. In an air conditioner that continues to operate the blower even after the temperature difference between the temperature and the temperature becomes equal to or less than a predetermined value, when the temperature difference is equal to or greater than a predetermined value, the movement of the wind direction changing plate is stopped; In the following cases, a drive device is provided to rotate the wind direction changing plate.

Due to the above configuration, the capacity control mechanism (inverter)
For those equipped with a compressor without
Sometimes, while the blower is running, the wind direction changing plate is automatically reciprocated by the action of the drive device, stirring the indoor air and making the indoor temperature distribution uniform. At this time, during heating, a weak wind is used to suppress the feeling of cold air. When the thermostat is turned on, the movement of the wind direction change plate is stopped to minimize the feeling of traft (during cooling).

In addition, for those equipped with a compressor and capacity control, when the room temperature approaches a certain range within the set temperature (the air direction changing plate remains stationary until it approaches), the air direction changing plate automatically moves back and forth. By doing so, it is possible to make the room temperature distribution uniform.

The reason for this is that when the room temperature approaches the set temperature, the compression function is generally controlled by lowering it, and by doing so, the evaporation temperature of the refrigerant increases during cooling, and therefore the temperature of the blown air also increases. It becomes difficult to feel the feeling of cold air, and indoor air can be stirred.

Conversely, during heating, the condensing temperature of the refrigerant decreases due to the decrease in capacity.
Therefore, the temperature of the blown air is also lowered, so the feeling of hot air is reduced, and at the same time, the specific gravity of the air is also increased, making it possible to increase the air agitation effect.

<Example> The present invention will be described below based on the drawings of the example.

Fig. 1 is a sectional view showing the main parts of a ceiling-embedded air conditioner. 1 is a unit main body, and the unit main body 1 has an indoor air suction grill 2 on the bottom surface, and a motor in the center of the interior. 3
At the same time, a heat exchanger 6 is installed on the side of the blower 5, and an air passage 7 from the heat exchanger 6 is connected to the outside of the suction grill 2. A wind direction changing plate 10 equipped with a drive device 9 having a motor is installed at the position of the air outlet 8 so as to be capable of automatic reciprocating movement, and the air conditioner 11 is installed in the ceiling as a whole.
becomes. 12 is a ceiling panel, and 13 is a ceiling. -Next, to explain this function, first, when the blower 5 is activated, indoor air flows from the suction grill 2 into the unit body due to the suction action of the fan 4, passes through the heat exchanger 6, undergoes a predetermined heat exchange, and becomes cold air or air. The warm air flows from the air passage 7 to the air outlet 08. In this case, the blower 5 continues to operate even after the indoor temperature reaches the set value, and the air direction change plate 10 disposed at the air outlet 8 stops moving until the indoor temperature reaches the set value. After reaching the set value, the wind direction changing plate 10 is rotated by the action of the drive unit W9 to equalize the temperature distribution in the room.

Alternatively, the blower 5 continues to operate even after the temperature difference between the indoor temperature and the set value becomes less than a predetermined value, and when the temperature difference is greater than or equal to the predetermined value, the movement of the wind direction changing plate 10 is stopped, and In the following cases, the drive device 9 operates to rotate.

Now, the operation of the wind direction changing plate 10 will be described in detail based on the flowchart shown in FIG. When the difference is less than a predetermined value A, the automatic reciprocating movement of the wind direction changing plate 10 is turned off, and when the capacity decreases, the movement of the wind direction changing plate 10 is turned on. Further, when the variable compression function is No and the current room temperature and the set temperature are the same, the compressor is turned off and the wind direction changing plate 10 is turned on.

<Effects of the Invention> As described above, the air conditioner of the present invention automatically reciprocates the wind direction changing plate disposed at the outlet after the compressor has stopped, while performing air blowing operation. By reciprocating,
Room temperature distribution is made uniform. In addition, in an air conditioner equipped with compressor capacity control, when the room temperature approaches the set temperature, the wind direction changing plate is moved back and forth, and the same effect can be achieved in making the room temperature distribution uniform.
