As another example, although the steps of the method of the present invention are described herein in a particular order, these orders are not limiting and one skilled in the art can perform the steps in a different order without departing from the underlying principles of the invention.
It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
First, referring to fig. 1 and 2, in which fig. 1 is a schematic structural view of an indoor unit of an embedded air conditioner according to an embodiment of the present invention, a first air guiding plate and a second air guiding plate shown in the drawings are both in an 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, in which a first air guiding plate and a second air guiding plate are both in an open state; fig. 3 is an enlarged schematic view of a portion a in fig. 2.
As shown in fig. 1, 2 and 3, the embedded air conditioner of the present invention includes an indoor unit and an outdoor unit, the indoor unit includes a casing, the casing includes a casing body 2 and a panel assembly 1 detachably disposed on the casing body 2, the panel assembly 1 includes a panel frame 11 and an air inlet grille 12, and the panel frame 11 is provided with a plurality of air outlets 111. The indoor unit further comprises a plurality of air guide plate groups, each air guide plate group comprises a first air guide plate 31 and a second air guide plate 32, the first air guide plate 31 is rotatably arranged on the panel frame 11 so as to be capable of plugging or opening the air outlet 111, the second air guide plate 32 is embedded in the first air guide plate 31, and the second air guide plate 32 can rotate non-coaxially relative to the first air guide plate 31.
It can be seen that the embedded air conditioner of the present invention has the second air guiding plate 32 embedded in the first air guiding plate 31, and the second air guiding plate 32 can rotate non-coaxially with respect to the first air guiding plate 31, and various air supply combinations can be formed by rotating the first air guiding plate 31 and the second air guiding plate 32 separately or simultaneously, so as to implement more various air direction controls, and further meet various air supply requirements of users. For example, when the first air deflector 31 rotates from the closed position to open the air outlet 111, the second air deflector 32 is opened at this time, which can split and guide the air flow, so as to form two air flows with different flow directions, thereby expanding the air supply range, and then the flow directions of the air flows 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. And secondly, the flatness of the air guide plate group can be ensured by the design of the embedded air guide plate group. In addition, compared with the coaxially arranged air guide plate group, the arrangement form of the second air guide plate 32 of the present invention can be more flexible, and a person skilled in the art can arrange the position of the second air guide plate 32 on the first air guide plate 31, the position of the pivot shaft of the second air guide plate, and the rotation direction of the second air guide plate according to actual requirements. As an example, the first air guiding plate 31 is pivotally disposed on the panel frame 11 through the rotating arm 34, the second air guiding plate 32 is disposed on the first air guiding plate 31 in an embedded manner, and a pivotal axis of the second air guiding plate 32 is disposed on a side of the second air guiding plate 32 away from the air outlet 111 along the air outlet direction, in the cooling/heating mode, the first air guiding plate 31 and the second air guiding plate 32 are respectively opened outward to a set angle, the first air guiding plate 31 will send a part of the cold/hot air to a space away from the embedded air conditioner, and the second air guiding plate 32 will send a part of the cold/hot air to a space below the embedded air conditioner, so that the cold/hot air can be sufficiently mixed with air in the indoor space, thereby improving the cooling/heating effect.
In one possible embodiment, as shown in fig. 3, the first air guiding plate 31 is provided with a mounting opening 3111 along the thickness direction thereof, and the second air guiding plate 32 is rotatably provided in the mounting opening 3111 so as to open or close the mounting opening 3111. When the second air guiding plate 32 is in the closed state, the mounting port 3111 is blocked by the second air guiding plate 32, and the airflow can be sent out only by the first air guiding plate 31. When the second air guiding plate 32 rotates, the mounting port 3111 is opened, and at this time, a part of the air flow is sent out from the mounting port 3111 under the guidance of the second air guiding plate 32, so as to perform a shunting function.
The shape of the mounting port 3111 may be various, and it is preferable to provide the mounting port 3111 in a rectangular shape for manufacturing, but the shape of the mounting port 3111 is not limited thereto, and may be circular, oval or other possible shapes. In addition, the number of the mounting openings is not limited to one in the example, and a plurality of mounting openings may be provided in the first air guiding plate and a second air guiding plate may be provided in each mounting opening to control opening and closing of the mounting openings. The shape, the number and the arrangement position of the mounting openings can be flexibly arranged according to actual conditions by a person skilled in the art.
It should be understood that the installation manner of the second air guiding plate 32 is not limited to the above-mentioned manner of installing in the installation opening 3111, and those skilled in the art can adjust the installation manner of the second air guiding plate 32 according to actual requirements. As an example, a gap is formed on a side of the first wind guiding plate 31 away from the wind outlet 111 along the wind outlet direction, and the second wind guiding plate 32 is rotatably disposed in the gap.
In a preferred embodiment, as shown in fig. 3, at least one side portion of the second air guiding plate 32 is formed with a first abutting structure, a second abutting structure is formed at a position corresponding to the first abutting structure on the outer edge of the mounting opening 3111, and the first abutting structure and the second abutting structure abut against each other when the mounting opening 3111 is blocked by the second air guiding plate 32. Through the arrangement of the first butt joint structure and the second butt joint structure, the surface flatness of the air guide plate group can be guaranteed, gaps of the two air guide plates can be reduced or even eliminated as far as possible, and particularly under the condition that the first air guide plate 31 is opened and the second air guide plate 32 is closed, the first butt joint structure and the second butt joint structure abut against each other to reduce or even eliminate gaps between the two air guide plates, so that air flow is prevented from leaking out of the gaps between the two air guide plates. In addition, the arrangement can also solve the problem that dust enters the shell from the gap to cause pollution inside the shell.
The specific form of the first docking structure and the second docking structure may be various, as shown in fig. 3, as an example, a side portion (right side shown in fig. 3) of the second air deflector 32 close to the inside of the housing is provided with a first step structure 321, a position of an outer edge of the mounting port 3111 corresponding to the first step structure 321 is provided with a second step structure 3112, and in a case where the second air deflector 32 blocks the mounting port 3111, the first step structure 321 abuts against the second step structure 3112. Through the arrangement of the (first and second) step structures, a good sealing effect can be achieved on a gap between the first air deflector 31 and the second air deflector 32, and the processing and production are facilitated.
It should be noted that the structures, numbers and arrangement positions of the first abutting structure and the second abutting structure are not limited to the above examples, and those skilled in the art can flexibly arrange them according to the actual situations. If a plate-shaped first abutting structure can be provided on each of the four side portions of the second air guide plate 32, a groove-shaped second abutting structure is provided at a position corresponding to the outer edge of the mounting opening 3111.
With continued reference to fig. 1, 2 and 3, in a preferred embodiment, the first air guiding plate 31 includes a first portion 311 and a second portion 312 in sequence along the air outlet direction, wherein the first portion 311 is substantially a horizontal flat plate structure, and the mounting port 3111 is disposed on the first portion 311. Through the arrangement, the mounting opening 3111 is close to the air outlet 111, so that the airflow coming out of the air outlet 111 flows to the mounting opening 3111 more easily, and the second air guiding plate is mounted on the first portion of the horizontal plate-shaped structure conveniently. The second portion 312 includes an upstream end and a downstream end in sequence along the air-out direction, and the upstream end of the second portion 312 is higher than the downstream end. Through the arrangement, the air flow can be guided to be sent out upwards, a large amount of air flow is prevented from blowing the user directly, and therefore the comfort of the user is improved. The shape of the second portion may be varied, and as an example, as shown in fig. 3, the second portion 312 has an arc-shaped plate-like structure.
It should be noted that the first portion 311 and the second portion 312 may also have other shapes, for example, the first portion 311 and the second portion 312 are both arc-shaped plate-shaped structures, or the first portion 311 and the second portion 312 are both horizontal plate-shaped structures. In addition, the shape of the first air guiding plate 31 is not limited to the two-section structure, for example, the first air guiding plate 31 may also be an arc-shaped structure as a whole, and a person skilled in the art may flexibly set the specific structure of the first air guiding plate 31 according to the actual situation so as to adapt to the specific application scenario.
Preferably, as shown in fig. 1, the panel frame 11 is provided with a docking slot 112 matching with the first air deflector 31, the first air deflector 31 is embedded in the docking slot 112 in the case that the first air deflector 31 blocks the air outlet 111, and the outer surface of the first air deflector is flush with the outer surface of the panel frame in the case that the first air deflector is completely embedded in the docking slot 112. The surface flatness of the panel assembly 1 can be improved by this arrangement.
Referring next to fig. 4 and 5, wherein fig. 4 is a schematic structural view of a panel assembly of an indoor unit of an embedded air conditioner according to an embodiment of the present invention; fig. 5 is an enlarged schematic view of a portion B in fig. 4. As shown in fig. 4 and 5, in one possible embodiment, a first air deflector motor box is disposed on the inner side (i.e., the side close to the housing body 2) of the panel frame 11, a first air deflector motor 33 (i.e., a first motor) is mounted in the first air deflector motor box, a rotating arm 34 is disposed on the first air deflector 31, and the first air deflector motor 33 drives the first air deflector 31 to rotate by driving the rotating arm 34. A second air deflector motor box is arranged on the inner side of the first air deflector 31, a second air deflector motor 35 (namely, a second motor) is installed in the second air deflector motor box, and the second air deflector motor 35 is used for driving the second air deflector 32 to rotate relative to the first air deflector 31.
Through the arrangement, the two air guide plates can independently rotate, and a user can selectively enable the two air guide plates to synchronously rotate for air guide or enable the two air guide plates to respectively rotate for air guide according to actual requirements. In addition, since the second air guiding plate 32 is disposed on the first air guiding plate 31, the second air guiding plate 32 can rotate with the first air guiding plate 31, and can also rotate relative to the first air guiding plate 31, so that a variety of air blowing modes can be formed.
Preferably, the number of the first air deflection motors 33 is two to improve the rotation reliability of the first air deflection plate 31, and the two motors are respectively disposed at positions close to both ends of the first air deflection plate 31 inside the panel frame 11 to make the weight distribution of the motors more uniform.
In practical applications, the second air guiding plate motor 35 is not necessary, and those skilled in the art can select whether to install the second air guiding plate motor 35 according to actual requirements. As an example, the first air guiding plate 31 is provided with a mounting opening 3111, the second air guiding plate 32 is rotatably disposed in the mounting opening 3111 through a pivot shaft, and a position of the first air guiding plate 31 corresponding to the pivot shaft is provided with a limiting device. The controller of the air conditioner controls the limiting device to lock and unlock the pivot shaft, and the second air deflector cannot rotate under the condition that the pivot shaft is locked; when the pivot shaft is unlocked, the first air guiding plate 31 swings back and forth under the driving of the first air guiding plate motor 33, and the second air guiding plate 32 also swings back and forth along with the first air guiding plate.
It will be understood by those skilled in the art that the built-in air conditioner obviously includes other parts and structures besides the parts of the built-in air conditioner described above, although not described in the embodiment, the parts should be understood according to the shapes and features of the built-in air conditioner in the prior art, and the shapes and features should not be construed as limiting the present invention. For example, the embedded air conditioner may further include a compressor, a heat exchanger, and the like.
Referring next to fig. 6, fig. 6 is a first flowchart illustrating a method for controlling an air deflector for cooling an air conditioner according to an embodiment of the present invention.

step S2: and under the condition that the air conditioner is in a refrigerating working condition, the second air deflector rotates to a closed position relative to the first air deflector.
The second air guiding plate 32 can rotate in various manners, and preferably, the second air guiding plate 32 is driven by the second air guiding plate motor to rotate the second air guiding plate 32 to the closed position relative to the first air guiding plate 31. It is to be understood that if the second air deflection plate 32 is initially in the closed position, the "rotation to the closed position" in step S2 is to be understood as "remaining in the closed position".
Step S3: the first air deflector is rotated to a set position.
In step S3, the second air guiding plate motor is controlled not to operate, and the first air guiding plate motor drives the first air guiding plate 31 so that the first air guiding plate 31 drives the second air guiding plate 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 requirements during the use process. In addition, multiple settings may be preset for user selection in a cooling mode
Step S4: the first air deflector can rotate back and forth within a set angle range.
In step S4, the second air guiding plate motor is controlled not to operate, and the first air guiding plate motor drives the first air guiding plate 31 so that the first air guiding plate 31 drives the second air guiding plate 32 to rotate back and forth within the set angle range. It can be understood that the specific value of the set angle range may be preset in advance in the factory stage, or may be set by the user according to actual requirements during the use process. In addition, in a refrigeration mode, the set angle range can be set to one group, and multiple groups can be preset for the user to select.
The advantage of above-mentioned setting lies in: when the second air deflector rotates to the closed position, the mounting port 3111 is blocked by the second air deflector 32, and the air flow cannot flow out from the mounting port 3111 and can only be intensively sent out by the first air deflector 31, so that the strength and speed of the air flow are ensured, and the air flow blowing distance is longer. The air outlet 111 is opened by rotating the first air deflector 31 to a set position, and the first air deflector is rotated back and forth within a set angle range to change the direction of the air flow, so that the air supply range is expanded, and the refrigeration effect is ensured.
In a preferred embodiment, the air conditioner presets a plurality of refrigeration modes (such as a direct blow-out prevention refrigeration mode, a normal refrigeration mode, etc.) under a refrigeration condition, and in this case, the air conditioner needs to determine which refrigeration mode the current operation mode is, and then determine a set position and a set angle range according to the current operation mode, so as to control the movement of the air guide plate group.
In view of the above, referring to fig. 7, fig. 7 is a flowchart illustrating 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, namely the step of "rotating the first air guiding plate to the set position", the control method of the present invention includes:
step S11: a current operation mode of the air conditioner is determined.
Step S12: and determining a set position and a set angle range according to the current operation mode.
Preferably, the air conditioner at least comprises a first operation mode, in the first operation mode, the second air deflector 32 rotates to a closed position relative to the first air deflector 31, the first air deflector 31 rotates to a first set position, and then the first air deflector 31 swings back and forth within a first set angle range. The first set angle range is 5-10 degrees, the included angle between the first set position and the horizontal plane is a first set angle, and the first set angle falls into the first set angle range.
The advantage of above-mentioned setting lies in: when the air conditioner is in the first operation mode, the first air deflector 31 is controlled to swing back and forth within the range of 5-10 degrees, and the smaller swing angle enables the first air deflector 31 to guide air flow at an angle close to the horizontal angle without directly blowing to a user, so that the comfort of the user is improved. In addition, the swing angle of the first air guiding plate 31 is small, so that the air outlet area between the first air guiding plate 31 and the panel frame is also small, and the flow velocity of the cold air flow is increased, and thus, the accelerated cold air flow is blown to a farther position under the guidance of the first air guiding plate 31 in the direction close to the horizontal direction. After the cold air flow is blown out, the cold air flow is heavier than indoor air, and the cold air flow and the air are mixed and then slowly fall down, so that the refrigeration effect is improved.
Further, the first operation mode is a direct blow prevention cooling mode, and the step of "determining the current operation mode of the air conditioner" specifically includes: detecting whether people exist in a space where the air conditioner is located; and determining the current operation mode of the air conditioner as a first operation mode under the condition that the person in the indoor space is detected. For example, whether a person is in the indoor space can be detected by a human body induction sensor installed on the air conditioner, and then the blow-through prevention cooling mode is selectively determined as the current operation mode according to the detection result.
Through the setting, the air conditioner can automatically execute the direct blowing prevention refrigeration mode under the condition that the indoor space is occupied without any operation of a user, so that the comfort level of the user is improved, and the user experience is improved.
Preferably, the air conditioner includes a second operation mode, in the second operation mode, the second air guiding plate 32 rotates to the closed position relative to the first air guiding plate 31, the first air guiding plate 31 rotates to the second setting position, and then the first air guiding plate 31 swings back and forth within the second setting angle range. The second set angle range is 5-45 degrees, the included angle between the second set position and the horizontal plane is a second set angle, and the second set angle falls into the second set angle range. Preferably, the second set angle is 45 °.
When the air conditioner is in the second operation mode, the first air deflector 31 is controlled to swing back and forth within the range of 5 degrees to 45 degrees to adjust the air supply area and the air supply angle, so that the cold air flow and the indoor air can be mixed.
It should be noted that the manner of determining the current operation mode of the air conditioner is not limited to the above example, and there may be many other manners, for example, a user sends a mode instruction through a remote controller or a voice control manner, the controller of the air conditioner receives the mode instruction sent by the user and determines the current operation mode selected by the user according to the mode instruction sent by the user, and then controls the movement of the air guide plate group according to the set position and the set angle range corresponding to the current operation mode.
It will be appreciated that the air conditioner may also have only one cooling mode, in which case the set position and set angular range are determined, and there is no need to determine the current operating mode.
Referring to fig. 8, fig. 8 is a second flowchart illustrating a method for controlling an air deflector for cooling of an air conditioner according to an embodiment of the present invention. As shown in fig. 8, in a preferred embodiment, after step S4, namely, the step of "rotating the first wind deflector back and forth within the set angle range", the control method further includes:
step S51: and acquiring the indoor environment temperature.
Step S52: judging whether the indoor environment temperature reaches a set target temperature:
if yes, go to step S53;
if not, step S51 is executed to continue collecting the indoor ambient temperature.
Step S53: the first air deflector is rotated to a set position and then stops rotating.
Under the condition that the indoor environment temperature reaches the target temperature set by the user, the first air deflector is controlled to rotate to the set position and then stops rotating, so that mechanical loss caused by long-time operation of the first air deflector motor 33 can be avoided, the service life of the first air deflector motor 33 is ensured, and energy can be saved.
The steps of the air deflector control method for air conditioner refrigeration according to the present invention will be further described with reference to the specific embodiment shown in fig. 9.

step S100: a mode instruction is fetched.
Step S200: and determining the current operation mode of the air conditioner according to the mode command.
In case that the current operation mode of the air conditioner is the first operation mode, performing step S310; in case that the current operation mode of the air conditioner is the second operation mode, step S320 is performed.
Step S310: the second air guiding plate rotates to a closed position relative to the first air guiding plate, the first air guiding plate rotates to a first set position which forms a 10-degree angle with the horizontal plane, and then the first air guiding plate swings in an angle range of 5-10 degrees.
Step S320: the second air guiding plate rotates to a closed position relative to the first air guiding plate, the first air guiding plate rotates to a second set position which forms an angle of 45 degrees with the horizontal plane, and then the first air guiding plate swings in an angle range of 5 degrees to 45 degrees.
Step S400: and acquiring the indoor environment temperature.
Step S500: judging whether the indoor environment temperature reaches a set target temperature:
if yes, go to step S600; if not, step S400 is executed to continue to acquire the indoor ambient temperature.
Step S600: the first air deflector is rotated to a set position and then stops rotating;
if step S310 is performed before step S400, the setting position is a first setting position; if step S320 is performed before step S400, the setting position is the second setting position.
In summary, in the embedded air conditioner of the present invention, the first air guiding plate 31 is provided with the mounting opening 3111, the second air guiding plate 32 is embedded in the mounting opening 3111, and the second air guiding plate 32 is rotated to split and guide the air flow, so as to further enrich the air supply manner and expand the air supply range. And the embedded design can ensure the external flatness of the air guide plate group. Preferably, a first air deflector motor 33 is arranged on the inner side of the panel frame 11, a second air deflector motor 35 is arranged on the inner side of the first air deflector 31, and the first air deflector 31 and the second air deflector 32 are respectively driven by the first air deflector motor 33 and the second air deflector motor 35 to respectively and independently rotate so as to form various air supply modes, so that more various air supply requirements of users are met, and user experience is improved.
