24 and 25 are views showing another conventional wind direction changing device for an air conditioner disclosed, for example, in Japanese Utility Model Laid-Open No. 63-147650. FIG. 24 is a cross-sectional view and FIG. FIG. 25 is a diagram for explaining the operating state of the device of FIG. 24. In the figure, (201) is a blowout port, (202) is an inner wall of the blowout port (201), (203) is a vane in which a plurality of sheets are arranged at the blowout port (201) at substantially equal intervals to change the wind direction. 2 as shown in FIG.
A set of a plurality of sheets is provided on each of the left and right sides of 4. Reference numeral (204) is a shaft which is erected on the inner wall (202) and arranged in each of the vanes (203), and which pivots one edge of one side of the vanes (203) toward one end.

Reference numeral (205) is a connecting arm that connects a pair of vanes (203), and a connecting shaft (206) that pivots the edge of each vane (203) on which the shaft (204) is arranged near the other end. ) Is provided, and the distance between the shaft (204) of the vane (203) near the center and the connecting shaft (206) in FIG. 24 is the same as the shaft (204) of the vane (203) near the outer side in FIG. It is set to be shorter than the interval of (206) and is arranged to be inclined with respect to the line connecting the axes (204) of the vanes (203) as shown in FIG.

Another conventional air conditioner changing device shown in FIGS. 24 and 25 is constructed as described above, and as shown in FIG. It is used by arranging so that the sides spread out.
In this state, the inclination of the vane (203) near the center of FIG.
Since the vanes (203) closer to the outer side are closer to the horizontal, the wind direction angles deflected by the respective vanes (203) are also inclined toward the outer side as shown by the solid arrows in FIG. 25. It is closer to horizontal than the vane (203). In addition, since a narrow gap is formed at the intermediate portion between the pair of vanes (203), the wind (207) blown out from this gap becomes weak because it does not flow smoothly, and the secondary air (208) around it is removed. Dew (209) is created in the entrainment vanes (203).

[0007]

In the conventional wind direction adjusting device for an air conditioner as described above, when the left and right deflection rods (20) are largely displaced, the pressure loss due to the guide vanes (8) increases, and the air passage The amount of air blown out through the outlet (4) through (13) is significantly reduced. As a result, the warm air does not reach the floor of the living room, especially during heating. Also, since the temperature of the blown air drops during cooling, dew adheres to each part of the outlet (4) and the main body (1) and may drip into the living room during operation or cause mold in the living room. Or Then, the blown airflow falls on the floor surface closer to the air conditioner as compared with when it is blown to the front, and the accuracy of airflow direction control is reduced.

Further, since the wind direction is largely regulated by the guide vanes (8), the air flow is separated and is condensed on each part of the blowout port (4) during cooling. Furthermore, when the air conditioner is installed near the wall of the living room, the blown airflow is reflected by the wall and is sucked through the suction port (3), so that the airflow does not circulate in the living room and a comfortable environment cannot be obtained. In order to prevent the above problems, it is necessary to regulate the deflection angle of the left and right wind direction deflection plates. On the other hand, conventionally, the left and right wind direction deflection plates have a structure in which the deflection angle does not rotate beyond the regulation angle. For this reason, for example, even during heating without dew condensation, it is impossible to blow air over this deflection angle due to the deflection angle regulation of the left and right air flow direction deflecting plates during cooling.

Further, when the air conditioner is installed near the wall, the angle at which the air is blown in the direction without the wall is restricted by the regulation of the deflection angles of the left and right air flow direction deflecting plates. For the above reasons
There is a problem in that it is difficult to blow air into the entire living room because the area in which air can be blown in the left-right direction is restricted and becomes narrow, and unevenness in temperature occurs and comfort is impaired.

The present invention has been made in order to solve the above problems, and an object of the present invention is to expand the area in which air can be blown in the left and right directions to improve the comfort of a living room. To get the adjustment device.

[0016]

In the wind direction adjusting device for an air conditioner according to the first aspect of the present invention, the rotational speed of the cross flow fan increases when the deflection angle of the left and right wind direction deflecting plates is large, so that the amount of air blown out of the left and right wind direction deflecting plates. The amount is almost the same as when the deflection angle is small. Therefore, even when the deflection angle of the right and left air flow direction deflecting plates is large, the temperature of the blowout airflow during cooling is kept relatively high, the backflow of air in the living room is prevented, and the dew condensation on the blowout opening is prevented. Is reduced. Further, even when the deflection angles of the left and right air flow direction deflecting plates are large, the warm air during heating reaches the floor surface and the comfort is maintained.

Is a casing which is provided in the main body (1) and forms an air passage (13).

A change (7) is pivotally attached to the left and right side walls of the blow-out port (4) by a shaft provided at the blow-out port (4) and attached to the left and right ends of the blow-out port (4) to convert the wind direction into a horizontal direction, a direct downward direction and an oblique direction.

The left and right wind direction deflecting plates consisting of guide vanes that are installed side by side between the walls of the left and right ends of each of them and are respectively pivoted to change the wind direction to the left and right, (12a) is the outlet (4) of the air passage (13). ) Side, and is a cross flow fan driven by the electric motor (18).

Reference numeral (119) is a driving means composed of a stepping motor for changing the inclination angle of the right and left wind direction deflecting plate (8), and (120)
Is a driving means composed of a stepping motor for changing the inclination angle of the vertical wind direction deflecting plate (7). Reference numeral (121) is a control device, which includes a rotation speed command section (122) of the electric motor (18) and a drive means (11
9), (120) drive amount detection unit (123) and drive amount command unit (124)
Is provided.

In the air direction adjusting device of the air conditioner constructed as described above, the air flow sent out from the cross flow fan (12a) is changed in direction by the left and right air flow direction deflecting plates (8) and the up and down air flow direction deflecting plates (7). Controlled. The left / right wind direction deflection plate (8) and the up / down wind direction deflection plate (7) are driven by the drive means (11
The deflection angle is changed by 9) and (120), and the electric motor (18)
The rotation speed of is controlled by the rotation speed command unit (122),
The momentum of the driving means (119), (120) is controlled by the drive amount detecting section (123) and the drive amount command section (124). Also, FIG.
FIG. 11 shows a system for determining the command content of each command unit in the control device (121).

That is, operation condition selection such as cooling, heating and dehumidification, vertical wind direction deflection angle selection, left and right wind direction deflection angle selection, and crossflow fan (12a) rotation speed selection, that is, operation mode selection is omitted. However, it is manually selected by each selection switch. Note that the selection switch surrounded by the broken line shown in FIG. 4 can also be automatically selected.
Then, the following correction is applied according to each selected condition, and the vertical wind direction deflection angle, the horizontal wind direction deflection angle, and the rotation speed of the cross flow fan (12a) are determined and input from each command unit.

The operation of the wind direction adjusting device of the air conditioner of the first embodiment will be described with reference to the flow chart shown in FIG. That is, in step S11, the right and left wind direction deflector (8)
When the deflection angle is selected, the right wind direction deflection plate (8) is driven by the drive means (119), (120) with 0 pulse when the left wind direction deflection plate (8) is deflected to the maximum. The deflection angle is set. Next, in step S12, the input value of the driving means (119), (120) is 160 pulses or less or 420
When the pulse is equal to or more than the pulse, that is, when the deflection angle of the right-and-left airflow direction deflecting plate (8) is 25 ° or more, the process proceeds to step S14, and the rotation speed of the crossflow fan (12a) is increased more than the regulation. If the deflection angle of the left / right air flow deflector (8) is 25 ° or less, the process proceeds to step S13, and the cross flow fan
The rotation speed of (12a) is set to the specified value.

In addition, the deflection angle of the right and left wind direction deflection plate (8) is set to 2
When it is deflected by 5 ° or more, the blown air flow is separated and the air in the living room flows into the blowout port (4), so that dew condensation easily occurs during cooling. Further, the smaller the amount of blown air, the easier the hot air will flow into the blowout port (4) due to the decrease in wind speed. Also, it is clear that the blowing air temperature is low, that is, the blowing air temperature decreases when the air volume passing through the heat exchanger (5) inside the main body (1) is small. Promote dew condensation on each part. For this reason, the deflection angle of the right and left wind direction deflection plate (8) is 25
When the temperature becomes higher than 0 °, the rotation speed of the cross flow fan (12a) is increased more than the specified speed to raise the temperature of the blown airflow so that the air in the room does not flow into the blowout port (4). Note that the above control can be obtained without requiring a special detecting element and without adding a component.

With the above-described structure, the area in which the air can be blown in the left and right directions is restricted and narrowed, so that it is difficult to blow air into the entire room, and uneven temperature occurs, which deteriorates comfort. The points are eliminated. Then, the comfort of the living room can be improved by expanding the blowable area in the left-right direction. In addition, the above control suppresses a decrease in the air volume during heating and enables the airflow to reach the floor of the living room, so that the comfort of the living room can be improved.

Example 2. 6 to 8 are views showing another embodiment of the present invention, FIG. 6 is a flow chart for explaining the operation of the wind direction adjusting device of the air conditioner of this embodiment, and FIG. 7 is a view of the air conditioner of FIG. FIG. 8 is a perspective view illustrating a blown state.
FIG. 7 is a perspective view for explaining another blowing condition of the air conditioner of FIG. 6, and the airflow direction adjusting device of the air conditioner has the same configuration as that of FIGS. 1 to 5 described above. The operation of the air-direction adjusting device of the air conditioner configured as described above will be described with reference to the flowchart shown in FIG.

That is, in step S21, the deflection angle of the left and right wind direction deflecting plate (8) is selected, and the process proceeds to step S22,
If the deflection angle of the left / right wind direction deflector (8) is not more than y °,
In step S23, the rotation speed of the cross flow fan (12a) is set to a specified value. In addition, left and right wind direction deflector
When the deflection angle of (8) is y ° or more, the process proceeds to step S24, and if the operation mode is not heating, the process proceeds to step S25, and the angle of the vertical wind direction deflecting plate (7) is made lower than the specified value. If the operation mode is heating in step S24, the process proceeds to step S26, and the vertical wind direction deflector (7)
The angle is set above the specified value.

For example, warm air is generally blown downward during heating, and at this time, if the angle of the vertical wind direction deflection plate (7) is a prescribed value, as shown in FIG. The arrival positions are equidistant from the main body (1), that is, they are arranged on an arc centered on the main body (1). And FIG.
As can be seen from the figure, the arrival position of the airflow on the floor of the living room is located closer to the installation surface of the main body (1) as the left / right wind direction deflection angle increases.

In the configuration of the second embodiment, the human body detection sensor is used to detect the direction of the person with respect to the air conditioner and the distance from the installation surface of the air conditioner to the person to detect the position. It is possible to improve comfort. In such a situation, when the deflection angle of the left / right air flow deflector (8) is large, the angle of the up / down air flow deflector (7) may be set upward to improve the position accuracy of the blowout airflow and improve comfort. it can. In the configuration of the second embodiment, the left and right wind direction deflection plates (8) are taken into consideration in consideration of the detection area of the human body detection sensor.
The deflection angle y ° is set to 30 °.

Further, in the second embodiment, in addition to the air conditioner using the human body detecting sensor, it is possible to obtain an effective action for improving the airflow direction control accuracy in the air conditioner in which the human body detecting sensor is not mounted. it can. Further, regardless of the operation mode, when the vertical wind direction deflection angle is downward from the predetermined value, the horizontal wind direction deflection plate (8) is increased in deflection angle to make the vertical wind direction deflection plate (7) upward, It is possible to improve the accuracy of the arrival position of the blown airflow and improve comfort. Further, in consideration of the characteristics of the air conditioner, when the deflection angle of the left / right air flow deflecting plate (8) is equal to or larger than a predetermined value, the angle of the up / down air flow deflecting plate (7) is always corrected upward so that the air is blown out. The accuracy of the position where the air flow reaches can be improved to improve comfort.

In cooling, generally, the vertical wind direction deflecting plate is used.
When (7) is used facing upward and the left and right wind direction deflection angle is large, the blowing air volume decreases and the blowing air velocity decreases. Therefore, the air flow blown out as shown by the arrow a in FIG. 8 does not circulate in the living room, and is easily sucked into the main body (1) through the suction port (3). In this state, the temperature of the blown airflow is lowered and dew condensation occurs on each part of the blowout port (4), which impairs the comfort of the living room. In order to solve such a problem, the angle of the vertical wind direction deflecting plate (7) is corrected downward to prevent the blowing airflow from flowing into the suction port (3). As a result, the blown airflow can circulate in the living room to maintain a comfortable environment, and the dew condensation of each part of the blowout port (4) can be prevented.

Example 3. 9 to 12 are also views showing another embodiment of the present invention, and FIG. 9 is a conceptual diagram showing the drive regions of the left and right airflow direction deflecting plates at the time of cooling and heating of the airflow direction adjusting device of the air conditioner of this embodiment. 10 is a conceptual diagram showing an example of left / right air flow direction deflection of the left / right air flow direction deflection plate corresponding to FIG. 9, FIG. 11 is a distribution diagram showing a 50 cm temperature distribution on the floor surface of the living room corresponding to FIG. 9, and FIG. FIG. 6 is a characteristic diagram showing the relationship between the left-right airflow direction deflection angle and the airflow volume, and the airflow direction adjusting device of the air conditioner is configured in the same manner as in FIGS. 1 to 5 described above. As shown in FIG. 9, in the wind direction adjusting device for an air conditioner having a plurality of left and right air flow direction deflecting plates (8), in heating around a reference line A perpendicular to the outlet (4) shown in FIG. The left and right wind direction deflecting plate (8) is driven up to a left and right deflection angle of 40 ° capable of blowing air throughout the living room.

Then, with respect to the deflection driving angle of the left and right wind direction deflector 8 during heating, the left and right wind direction deflector within the range of 25 ° left and right where no condensation occurs at the outlet 4 during cooling.
(8) is deflected. Due to this, during cooling, due to the good circulation of the cool air, importance is attached to the prevention of dew condensation, and the left and right wind direction deflection plates
Even if the deflection drive range of (8) is limited, a sufficiently comfortable living room environment can be obtained. In addition, the warm air, which is difficult to circulate in the living room during heating, reaches the necessary place in the living room by the left and right air flow direction deflecting plate (8) having a wide deflection driving range and can quickly heat the room.

Further, in the embodiment shown in FIGS. 9 to 12, the driving system of the left and right air flow direction deflecting plate (8) has two systems, so that the comfort in the living room can be further improved by diffusing the blown airflow. it can. It is to be noted that each of the living rooms when the left and right wind direction deflection plates (8) are set to different angles to diffuse the blown airflow in FIG. 11a and when the left and right wind direction deflection plates (8) are set to the same angle in FIG. 11b A temperature distribution of 50 cm on the floor is shown. Figure 1
The main body (1) is installed at the blackened position in FIG. 1, and the state in which air is blown from the main body (1) to the right is shown corresponding to FIG. Further, the shaded area in FIG. 11 is a range that is judged to be comfortable from the top of the temperature distribution, and as is clear from FIG. 11, it is possible to obtain a wider comfortable space by diffusing and blowing the airflow.

FIG. 12 shows the relationship between the main flow angle of the air flow and the air volume at the same rotation speed of the cross flow fan (12a) when the right and left air flow direction deflector (8) angles are set to be equal. As is clear from FIG. 12, when the left and right sides are set to different angles, the decrease in the air volume due to the change in the wind direction is small. That is, it can be said that the amount of warm air blown out is larger than when the right and left air flow direction deflector (8) angles are set to be equal, which is excellent in terms of both performance and comfort. In the case of the embodiments of FIGS. 9 to 12, the blowout airflow was diffused, but there are cases where the contraction of the blowout airflow is effective due to the characteristics of the control device (121).

Example 4. 13 and 14 are also diagrams showing another embodiment of the present invention, FIG. 13 is a flow chart for explaining the operation of the wind direction adjusting device of the air conditioner of this embodiment, and FIG. 14 is of the air conditioner of FIG. FIG. 6 is a schematic view of the left and right air flow direction deflecting plates showing the operation, and the air flow direction adjusting device of the air conditioner has the same configuration as that in FIGS. 1 to 5 described above. That is, it is possible to expand the deflection drive area of the left and right air flow direction deflecting plate (8) during cooling by the method described below in the embodiment of FIGS. The operation of the wind direction adjusting device of the air conditioner as described above will be described with reference to the flowchart shown in FIG.

That is, if the operation mode is selected in step S31 and the process proceeds to step S32, and if the cooling is not selected, the process proceeds to step S33 and the deflection angle of the left and right wind direction deflecting plate (8) is set to a specified value. If cooling is selected, the process proceeds to step S34, and if the deflection angle of the left / right airflow direction deflecting plate (8) is not 25 ° or more, the process returns to step S33. Also,
In step S34, the deflection angle of the left / right wind direction deflector (8) is set to 25.
If it is equal to or more than 0 °, the process proceeds to step S35, and after a lapse of a predetermined time from the activation of the air conditioner, the deflection angle of the left / right airflow direction deflecting plate (8) is set to 25 °.

For example, the left and right wind direction deflector (8) is moved to the left,
When the air conditioner is started when the right / left air flow deflector (8) is deflected to the right, the temperature of the room is high and the low-temperature airflow makes the human body uncomfortable. It is desirable to do. On the contrary, when the temperature of the living room becomes stable around the set temperature, there is little difference between the temperature of the blown airflow and the temperature of the living room, so that the airflow comes into contact with the human body and the user feels comfortable.

Further, in order to increase the comfort at the time of starting the air conditioner, the deflection angle of the left and right wind direction deflecting plates (8) is increased, and when the operation is continued while maintaining the angle, the left and right wind direction deflecting plates (8) ) Becomes an obstacle, and the separation of the blown air flow occurs. This causes dew condensation on each part of the blow-out port (4), but dew condensation can be prevented by reducing the deflection angle of the left-right airflow direction deflection plate (8). As a result, the separation of the blown air flow can be eliminated and the dew condensation on each part of the blowout port (4) can be prevented.

For the above reasons, when the air conditioner is started up, the air is blown along the wall of the living room so as not to make people in the living room uncomfortable. Then, after a lapse of a predetermined time when the temperature of the living room decreases, the deflection angle of the right and left wind direction deflecting plates (8) is set to 25 °
By making it small, it gives a feeling of air flow to the person in the living room and prevents dew condensation on each part of the blow-out port (4). It should be noted that such an action can be similarly obtained when the left and right air flow direction deflecting plates (8) are deflected in the same direction, that is, when the air is blown to the right or left of the main body (1).

Example 5. 15 to 18 are also views showing another embodiment of the present invention, and FIG. 15 is a flow chart for explaining the operation of the wind direction adjusting device of the air conditioner of this embodiment,
FIG. 16 is a plan view showing a wall-side installation example of the air-conditioning apparatus of FIG. 15, FIG. 17 is a plan view showing a ventilation state in FIG. 15, and FIG. 18 is a conceptual illustration of a deflection angle correction example of the left and right airflow direction deflecting plates in FIG. It is a top view shown, and the air direction adjusting device of an air harmony device is constituted like the above-mentioned Drawing 1-Drawing 5. That is, the reference line A in FIG. 9 depending on the installation position of the main body (1) can be corrected by the method described below in the embodiments of FIGS. The operation of the wind direction adjusting device of the air conditioner as described above will be described with reference to the flowchart shown in FIG.

That is, in step S41, as shown in FIG.
As shown in, the installation status of whether the installation position of the main body (1) is near the left wall, near the right wall, or other than that is set. Then, the process proceeds to step S42, and if it is not the left wall or the right wall, the process proceeds to step S43 to set the deflection drive reference line of the left / right air flow direction deflecting plate (8) to 0 °. If it is near the left wall or the right wall in step S42, the process proceeds to step S44, and as shown in FIG. 18, the deflection drive reference line of the left / right airflow direction deflecting plate (8) is corrected by 35 ° in the direction without the wall.

That is, when there is a wall on the left side of the main body (1) or a wall on the right side, if the blast angle toward the wall is large, the blown airflow will flow as shown by the solid line in FIG. Is not circulated and is sucked in through the suction port (3). Also,
If the main body (1) has a room temperature sensor (not shown), cold and hot air blown out from the air outlet (4) may directly hit the room temperature sensor and cause an erroneous detection of the room temperature.
In such a situation, there will be a reduction in both comfort and cooling and heating performance.

On the other hand, the blast angle toward the wall is shown in FIG.
As shown by the broken line in FIG. 7, the wall surface of the airflow can be prevented from being reflected and the airflow can be circulated in the living room by setting the wall surface at an angle that does not reflect the airflow. This improves comfort and prevents a decrease in both cooling and heating performance. In addition, the air-blowing area can be expanded in the direction without walls, and it is possible to blow air to every corner of the living room, and it is possible to blow air to any part of the living room regardless of the installation position of the main body (1).

As described above, according to the first aspect of the present invention, the crossflow fan provided in the main body and the blowout air from the crossflow fan provided at the outlet of the main body are vertically deflected. The vertical wind direction deflecting plate and the left and right wind direction deflecting plates that are connected to each other to deflect left and right, the driving means that is provided in the main body and that changes the deflection angle of the left and right wind direction deflecting plate, and the deflection angle of the driving means. A control device for controlling the amount of change and increasing the rotational speed of the crossflow fan when the deflection angle of the left-right airflow direction deflector due to the operation of the drive means exceeds a predetermined value.

As a result, the rotational speed of the crossflow fan increases when the deflection angle of the left / right air flow direction deflection plate is large, and the amount of blown air becomes approximately the same as when the deflection angle of the left / right air flow direction deflection plate is small. Therefore, even when the deflection angle of the right and left air flow direction deflecting plates is large, the temperature of the blowout airflow during cooling is kept relatively high, the backflow of air in the living room is prevented, and the dew condensation on the blowout opening is prevented. Is prevented. Therefore, there is an effect that the lateral ventilation area can be expanded and the comfort of the living room can be improved with a small manufacturing cost without requiring special components.

Further, as described above, the invention according to claim 2 of the present invention deflects the cross-flow fan provided in the main body and the blowing air from the cross-flow fan provided at the outlet of the main body up and down.

The control device controls the amount of change and controls the up-down air-direction deflection plate downward during cooling and when the deflection angle of the left-right air-direction deflection plate is larger than a predetermined value, and controls the up-down air-direction deflection plate upward during heating. .

As a result, when the deflection angle of the left / right airflow direction deflection plate is larger than the predetermined value, the vertical airflow direction deflection plate becomes downward from the specified state during cooling, and the vertical airflow direction deflection plate becomes upward from the specified state during heating. . Therefore, there is an effect that the accuracy of the arrival direction of the blown airflow is improved, and the comfort of the living room is improved by preventing the deterioration of cooling and heating performance.

As described above, in the invention according to claim 3 of the present invention, the crossflow fan provided in the main body and the blowout air from the crossflow fan provided in the outlet of the main body are deflected vertically. The vertical wind direction deflecting plate and the left and right wind direction deflecting plates that are connected to each other to deflect left and right, the driving means that is provided in the main body and that changes the deflection angle of the left and right wind direction deflecting plate, and the deflection angle of the driving means. The control device controls the amount of change and controls the deflection angle of the left and right wind direction deflection plates to be reduced during cooling, and to enlarge the deflection angle of the left and right air direction deflection plates during heating.

As a result, the deflection angle of the left / right air flow deflector is reduced during cooling, and the deflection angle of the left / right air flow deflector is increased during heating. Therefore, during cooling, it is possible to prevent dew condensation due to cold air and a comfortable living room environment is obtained, and during heating, warm air reaches the necessary place in the room and can quickly heat it, improving the comfort of the room. There is.

As described above, in the invention according to claim 4 of the present invention, the crossflow fan provided in the main body and the blowout air from the crossflow fan provided in the outlet of the main body are deflected vertically. The vertical wind direction deflecting plate and the left and right wind direction deflecting plates that are connected to each other to deflect left and right, the driving means that is provided in the main body and that changes the deflection angle of the left and right wind direction deflecting plate, and the deflection angle of the driving means. A control device is provided for controlling the amount of change and for reducing the deflection angle of the left and right wind direction deflection plates after a predetermined time has elapsed from the start of the cooling operation when the deflection angle of the left and right air direction deflection plates during cooling is larger than a predetermined value. .

As a result, when the deflection angle of the left / right airflow direction deflecting plate is larger than the predetermined value during cooling, the deflection angle of the left / right airflow direction deflecting plate is reduced after a predetermined time has elapsed from the start of the cooling operation. As a result, when the cooling operation is started, the air is blown away from the center of the living room and is gradually blown toward the center. Therefore,
At the start of the cooling operation, the low-temperature airflow makes the human body uncomfortable, so it is blown away from the people in the room, and when the room temperature stabilizes near the set temperature, the airflow touches the human body.
Further, there is an effect that the dew condensation on each part of the outlet is reduced and the comfort of the living room is improved.

As described above, according to the fifth aspect of the present invention, the crossflow fan provided in the main body and the blowout air from the crossflow fan provided at the outlet of the main body are vertically deflected.

A control device that controls the amount of change and that corrects the deflection area of the left and right wind direction deflector plate to the direction without the wall surface when one side surface of the main body is arranged close to the wall surface of the living room in which the main body is installed. Is.

Thus, when one side surface of the main body is arranged close to the wall surface of the living room in which the main body is installed, the deflection area of the left and right wind direction deflecting plate is corrected in the direction without the wall surface. As a result, the direction of the blown airflow becomes equal to or less than the angle at which it does not reflect on the wall surface, and the air circulates normally in the living room. Therefore, regardless of the installation position of the main body, cooling and heating performance can be prevented from being degraded, and the comfort of the living room can be improved.
