1 and 2, wherein, FIG. 1 is a schematic structural diagram of an indoor unit of a built-in air conditioner according to an embodiment of the present invention, and the first air guide plate and the second air guide plate shown in the figure are both Open state; FIG. 2 is a schematic cross-sectional view of an indoor unit of an embedded air conditioner according to an embodiment of the present invention, and the first air deflector and the second air deflector shown in the figure are both in an open state; FIG. 3 shows An enlarged schematic view of part A in FIG. 2 .

As shown in FIG. 1 , FIG. 2 and FIG. 3 , the embedded air conditioner of the present invention includes an indoor unit and an outdoor unit, the indoor unit includes a casing, and the casing includes a casing body 2 and is detachably arranged on the casing body 2 The panel assembly 1 includes a panel frame 11 and an air inlet grill 12, and the panel frame 11 is provided with a plurality of air outlets 111. The indoor unit also includes a plurality of air deflector groups, the air deflector group includes a first air deflector 31 and a second air deflector 32, the first air deflector 31 is rotatably arranged on the panel frame 11 so as to be able to seal. The air outlet 111 is blocked or opened, the second air guide plate 32 is embedded on the first air guide plate 31 and the second air guide plate 32 can rotate non-coaxially with respect to the first air guide plate 31 .

It can be seen that the embedded air conditioner of the present invention is provided with a second air guide plate 32 in an embedded manner on the first air guide plate 31 so that the second air guide plate 32 can be different from the first air guide plate 31 By rotating the shaft, a variety of air supply combinations can be formed by rotating the first air deflector 31 and the second air deflector 32 individually or simultaneously, thereby realizing more diverse wind direction control, thereby meeting the diverse air supply needs of users. For example, when the first air deflector 31 is rotated from the closed position to open the air outlet 111, the second air deflector 32 is opened at this time, which can divert and guide the airflow, forming two airflows with different directions, thereby The air supply range is expanded, and then the flow direction of each air flow can be changed by adjusting the rotation angles of the first air deflector 31 and the second air deflector 32, so that the air flow can be blown to multiple areas of the indoor space. Secondly, the design of the embedded air deflector group can ensure the flatness of the air deflector group. In addition, compared with the coaxially arranged air guide plate group, the setting form of the second air guide plate 32 of the present invention can be more flexible, and those skilled in the art can adjust the second air guide plate 32 in the first guide plate according to actual needs. The position on the wind plate 31, the position of the pivot shaft of the second wind guide plate and the rotation direction of the second wind guide plate are set.

In the cooling/heating mode, the first air deflector 31 and the second air deflector 32 are respectively opened outward. At the set angle, the first air deflector 31 will send part of the cold/hot air to the space far from the built-in air conditioner, and the second air deflector 32 will send part of the cold/hot air to the space below the built-in air conditioner In this way, the cold/hot airflow can be fully mixed with the air in the indoor space, thereby improving the cooling/heating effect.

In a possible implementation manner, as shown in FIG. 3 , the first air guide plate 31 is provided with an installation opening 3111 along its thickness direction, and the second air guide plate 32 is rotatably disposed in the installation opening 3111 so as to Open or block the installation port 3111. When the second air deflector 32 is in the closed state, the installation port 3111 is blocked by the second air deflector 32 , and the airflow can only be sent out by the first air deflector 31 . When the second air deflector 32 rotates, the installation port 3111 is opened, and a part of the air flow will be sent out from the installation port 3111 under the guidance of the second air deflector 32 , thereby playing a role of diverting the flow.

It can be understood that the installation method of the second air deflector 32 is not limited to the above-mentioned method of being disposed at the installation port 3111 , and those skilled in the art can adjust the installation method of the second air deflector 32 according to actual needs. As an example, a notch is formed on the side of the first air deflector 31 away from the air outlet 111 along the air outlet direction, and the second air deflector 32 is rotatably disposed in the notch.

In a preferred embodiment, as shown in FIG. 3 , at least one side portion of the second air deflector 32 is formed with a first butt structure, and a position corresponding to the first butt structure is formed on the outer edge of the installation opening 3111 . In the docking structure, when the second air deflector 32 blocks the installation opening 3111 , the first docking structure and the second docking structure abut against each other. Through the arrangement of the first butt joint structure and the second butt joint structure, while ensuring the surface flatness of the wind deflector group, the gap between the two wind deflectors can be reduced or even eliminated as much as possible, especially in the first wind deflector 31 When the second air deflector 32 is opened and the second air deflector 32 is closed, the first butt structure and the second abutment structure abut against each other to reduce or even eliminate the gap between the two air deflectors, thereby preventing airflow from the two air deflectors leaked from the gap between. In addition, this arrangement can also solve the problem that dust enters the casing from the gap and causes contamination inside the casing.

The specific forms of the first butt-jointing structure and the second butt-jointing structure can be various. As an example, as shown in FIG. side) is provided with a first stepped structure 321, and a second stepped structure 3112 is provided at the position corresponding to the outer edge of the installation opening 3111 and the first stepped structure 321. When the second air deflector 32 blocks the installation opening 3111, the A stepped structure 321 abuts against the second stepped structure 3112 . Through the arrangement of the (first and second) step structures, the gap between the first air guide plate 31 and the second air guide plate 32 can be well sealed, and the processing and production are facilitated.

It should be noted that the structures, numbers and arrangement positions of the first docking structure and the second docking structure are not limited to the above examples, and those skilled in the art can flexibly set them according to actual conditions. If the four sides of the second air deflector 32 can be provided with a plate-shaped first abutting structure, a groove-shaped second abutting structure is provided at a position corresponding to the outer edge of the installation opening 3111 .

1, 2 and 3, in a preferred embodiment, the first air deflector 31 includes a first part 311 and a second part 312 in sequence along the air outlet direction, wherein the first part 311 is substantially a horizontal plate Like structure, the installation opening 3111 is provided on the first part 311 . The above arrangement can make the installation port 3111 close to the air outlet 111, so that the airflow from the air outlet 111 can flow to the installation port 3111 more easily, and the first part of the horizontal plate-like structure also facilitates the installation of the second air deflector. The second portion 312 sequentially includes an upstream end and a downstream end along the air outlet direction, and the upstream end of the second portion 312 is higher than the downstream end. With this arrangement, the airflow can be guided to be sent upwards, so as to avoid a large amount of airflow directly blowing the user, thereby improving the user's comfort. The shape of the second part can be various. As an example, as shown in FIG. 3 , the second part 312 is an arc-shaped plate structure.

It should be noted that the first part 311 and the second part 312 can also be in other shapes, for example, the first part 311 and the second part 312 are both arc-shaped plate structures, or the first part 311 and the second part 312 are both horizontal plate-shaped structure. In addition, the shape of the first air deflector 31 is not limited to a two-section structure. For example, the first air deflector 31 can also be an arc structure as a whole. Those skilled in the art can flexibly set the shape of the first air deflector 31 according to the actual situation. Specific structure in order to adapt to specific application scenarios.

Preferably, as shown in FIG. 1 , the panel frame 11 is provided with a docking groove 112 matching with the first air guide plate 31 . When the first air guide plate 31 blocks the air outlet 111 , the first air guide plate 31 is embedded in the In the butting groove 112, and when the first air deflector is completely embedded in the butting groove 112, the outer surface of the first air deflector is flush with the outer surface of the panel frame. With this arrangement, the surface flatness of the panel assembly 1 can be improved.

4 and 5 , wherein FIG. 4 is a schematic structural diagram of a panel assembly of an indoor unit of a built-in air conditioner according to an embodiment of the present invention; FIG. 5 is an enlarged schematic diagram of part B in FIG. 4 . As shown in FIG. 4 and FIG. 5 , in a possible implementation manner, the inner side of the panel frame 11 (ie, the side close to the housing body 2 ) is provided with a first air deflector motor box, and the first air deflector motor A first wind deflector motor 33 (ie, a first motor) is installed in the box, a rotating arm 34 is arranged on the first wind deflector 31 , and the first wind deflector motor 33 drives the first wind deflector 31 by driving the rotating arm 34 turn. The inner side of the first air deflector 31 is provided with a second air deflector motor box, and a second air deflector motor 35 (ie, the second motor) is installed in the second air deflector motor box, and the second air deflector motor 35 is used for To drive the second wind deflector 32 to rotate relative to the first wind deflector 31 .

The independent rotation of the two wind deflectors can be achieved through the above arrangement, and the user can selectively rotate the two wind deflectors to guide the wind synchronously or rotate the two wind deflectors to guide the wind independently according to actual needs. In addition, since the second air guide plate 32 is disposed on the first air guide plate 31 , the second air guide plate 32 can rotate with the first air guide plate 31 and rotate relative to the first air guide plate 31 , in this way, a more abundant and diverse air supply method can be formed.

Preferably, the number of the first air deflector motors 33 is set to two in order to improve the rotation reliability of the first air deflector 31 , and the two motors are respectively arranged on the inner side of the panel frame 11 and close to the first air deflector 31 . The position of both ends of the motor makes the weight distribution of the motor more balanced.

It should be noted that, in practical applications, the setting of the second wind deflector motor 35 is not necessary, and those skilled in the art can choose whether to install the second wind deflector motor 35 according to actual needs. As an example, the first air guide plate 31 is provided with an installation opening 3111, the second air guide plate 32 is rotatably disposed in the installation opening 3111 through a pivot shaft, and the first air guide plate 31 is set at a position corresponding to the pivot shaft Limiting device. The controller of the air conditioner realizes the locking and unlocking of the pivot shaft by controlling the limiting device. When the pivot shaft is locked, the second air guide plate cannot be rotated; when the pivot shaft is unlocked, the first air guide plate cannot be rotated. When the plate 31 swings back and forth under the driving of the first air deflector motor 33, the second air deflector 32 also swings back and forth with the first air deflector.

Those skilled in the art can understand that, in addition to the components of the built-in air conditioner described above, the built-in air conditioner obviously also includes other components and structures. Although not described in this embodiment, these components should be The shapes and features possessed by built-in air conditioners in the prior art should be understood, and these shapes and features should not be construed as limiting the present invention. For example, the built-in air conditioner may also include a compressor, a heat exchanger, and the like.

Next, referring to FIG. 6 , FIG. 6 is a schematic flowchart 1 of a method for controlling an air deflector for cooling an air conditioner according to an embodiment of the present invention. As shown in FIG. 6 , based on the structure of the above air conditioner, the present invention also provides a method for controlling an air deflector for cooling the air conditioner. The air deflector control method of the present invention includes:

Step S2: when the air conditioner is in a cooling condition, rotate the second air deflector to a closed position relative to the first air deflector.

There are various ways of rotating the second wind deflector 32. Preferably, the second wind deflector 32 is driven by the second wind deflector motor to rotate the second wind deflector 32 relative to the first wind deflector 31 until it is closed. Location. It can be understood that, if the second air deflector 32 is located in the closed position from the beginning, then "turning to the closed position" in step S2 should be understood as "remaining in the closed position".

Step S3: Rotate the first air deflector to the set position.

In step S3, the second air deflector motor is controlled not to run, and the first air deflector 31 is driven by the first air deflector motor so that the first air deflector 31 drives the second air deflector 32 to rotate to the set position. It can be understood that the setting position may be preset in advance at the factory stage, or may be set by the user according to actual needs during use. In addition, in a cooling mode, multiple setting positions can be preset for the user to choose

Step S4: Rotate the first air deflector back and forth within the set angle range.

In step S4, the second wind deflector motor is controlled not to run, and the first wind deflector 31 is driven by the first wind deflector motor so that the first wind deflector 31 drives the second wind deflector 32 within the set angle range Rotate back and forth. It can be understood that the specific value of the set angle range may be preset in advance at the factory stage, or may be set by the user according to actual needs during use. In addition, in a cooling mode, the set angle range can not only be set in one group, but also can be preset in multiple groups for the user to choose.

The advantage of the above arrangement is that: when the second air deflector is rotated to the closed position, the installation port 3111 is blocked by the second air deflector 32, and the airflow cannot flow out from the installation port 3111 and can only be concentrated by the first air deflector. The plate 31 is sent out, in this way, the intensity and speed of the air flow are ensured, so that the air flow can be blown out farther. By rotating the first air deflector 31 to a set position to open the air outlet 111, and rotating the first air deflector back and forth within a set angle range to change the airflow direction, thereby expanding the air supply range and ensuring the cooling effect.

In a preferred embodiment, the air conditioner is preset with multiple cooling modes (such as anti-direct-blowing cooling mode, normal cooling mode, etc.) under cooling conditions. In this case, the air conditioner needs to determine the current operating mode Which cooling mode is selected, and then determine the set position and set angle range according to the current operating mode, and then control the movement of the air deflector group.

In view of this, referring to FIG. 7 next, FIG. 7 is a schematic flowchart of a method for determining a set position and a set angle range according to an embodiment of the present invention. As shown in FIG. 7 , at least before step S3, that is, the step of “rotating the first air deflector to the set position”, the control method of the present invention includes:

Step S11: Determine the current operating mode of the air conditioner.

Step S12: Determine the set position and the set angle range according to the current operation mode.

Preferably, the air conditioner includes at least a first operation mode. In the first operation mode, the second air guide plate 32 is rotated relative to the first air guide plate 31 to the closed position, and the first air guide plate 31 is rotated to the first air guide plate 31. After setting the position, the first wind deflector 31 is swung back and forth within the first set angle range. The first set angle range is 5-10°, the angle between the first set position and the horizontal plane is the first set angle, and the first set angle falls within the first set angle range.

The advantage of the above arrangement is that: when the air conditioner is in the first operating mode, the first air deflector 31 is controlled to swing back and forth in the range of 5° to 10°, and the smaller swing angle enables the first air deflector 31 to be guided at a near-horizontal angle. Airflow, without blowing directly at the user, improves user comfort. In addition, the swinging angle of the first air deflector 31 is small, so that the air outlet area between the first air deflector 31 and the panel frame is also small, thereby increasing the flow rate of the cold air flow. Under the guidance of the first wind deflector 31 close to the horizontal direction, it will blow to a farther position. After the cold air is blown out, because the cold air is heavier than the indoor air, the cold air is mixed with the air and then falls slowly, thereby improving the cooling effect.

Further, the first operation mode is the direct blowing prevention cooling mode, and the step of "determining the current operation mode of the air conditioner" specifically includes: detecting whether there is a person in the space where the air conditioner is located; In the case of a person, it is determined that the current operating mode of the air conditioner is the first operating mode. For example, it is possible to detect whether there is a person in the indoor space through the human body induction sensor installed on the air conditioner, and then selectively determine the anti-direct blowing cooling mode as the current operating mode according to the detection result.

Through the above setting, the air conditioner will automatically execute the anti-direct blowing cooling mode when there are people in the indoor space without any operation by the user, thereby improving user comfort and user experience.

Preferably, the air conditioner includes a second operating mode. In the second operating mode, the second air deflector 32 is rotated relative to the first air deflector 31 to the closed position, and the first air deflector 31 is rotated to the second setting. After setting the position, the first wind deflector 31 is swung back and forth within the second set angle range. The second set angle range is 5° to 45°, the angle between the second set position and the horizontal plane is the second set angle, and the second set angle falls within the second set angle range. Preferably, the second set angle is 45°.

When the air conditioner is in the second operating mode, by controlling the first air deflector 31 to swing back and forth in the range of 5° to 45° to adjust the air supply area and air supply angle, so that the cold air flow can be mixed with the indoor air.

It should be noted that the way of determining the current operating mode of the air conditioner is not limited to the above example, and there can be many other ways, for example, the user sends a mode command through a remote control or voice control, and the controller of the air conditioner receives the data sent by the user. The mode command determines the current operation mode selected by the user according to the mode command issued by the user, and then controls the movement of the wind deflector group according to the set position and the set angle range corresponding to the current operation mode.

It can be understood that, the air conditioner may also have only one cooling mode. In this case, the set position and the set angle range are determined, and the current operation mode does not need to be determined at this time.
