The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
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 deflector and a second air deflector 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 deflector and a second air deflector are both shown 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 arranged on the first air guide plate 31 in an embedded mode, 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 deflector 32 embedded in the first air deflector 31, and the second air deflector 32 can rotate non-coaxially with respect to the first air deflector 31, and various air supply combinations can be formed by rotating the first air deflector 31 and the second air deflector 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, forming a plurality of air flows with different flow directions, thereby expanding the air supply range, 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 a plurality of 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 axis 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 the pivot 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 outwards, the first air guiding plate 31 will deliver part of the cold/hot air to a space away from the embedded air conditioner, and the second air guiding plate 32 will deliver part of the cold/hot air to a space below the embedded air conditioner, so that the cold/hot air and the air can be fully mixed, 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 guide plate 32 is in the closed state, the mounting port 3111 is blocked by the second air guide plate 32, and the air flow can be sent out only by the first air guide plate 31. When the second air deflector 32 rotates, the mounting port 3111 is opened, and at this time, part of the air flow is guided by the second air deflector 32 and sent out from the mounting port 3111, 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, the first wind deflector 31 is formed with an installation notch along the side of the wind outlet direction far from the wind outlet 111, and the second wind deflector 32 is rotatably disposed in the installation 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 abutting structure, a second abutting structure is formed at a position where an outer edge of the mounting port 3111 corresponds to the first abutting structure, and the first abutting structure and the second abutting structure abut against each other under the condition that the second air deflector 32 blocks the mounting port 3111. 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, and meanwhile, the gap between the two air guide plates can be reduced or even eliminated as far as possible, 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 are abutted against each other to reduce or even eliminate the gap between the two air guide plates, so that air flow is prevented from leaking out of the gap 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, the numbers and the arrangement positions of the first and second docking structures 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 sequentially includes a first portion 311 and a second portion 312 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 port 3111 can be close to the air outlet 111, so that the air flow coming out of the air outlet 111 can flow to the mounting port 3111 more easily, and the first part of the horizontal plate-shaped structure is convenient for mounting the second air deflector. The second portion 312 includes an upstream end and a downstream end in the air outlet direction in order, 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 a 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 flatness of the surface 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 casing 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 deflectors can independently rotate, and a user can selectively enable the two air deflectors to synchronously rotate for air guiding or enable the two air deflectors to respectively rotate for air guiding 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 also can rotate relative to the first air guiding plate 31, so that a richer and more diversified air supply 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.
It should be noted that, in practical applications, the second air guiding plate motor 35 is not necessarily provided, and those skilled in the art can select whether to provide 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 present 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.

step S10: under the condition that the air conditioner is in a heating working condition, the first air deflector is rotated to a first set position.
In step S10, the second air guiding plate motor 35 is controlled not to operate, and the first air guiding plate 31 is driven by the first air guiding plate motor 33, so that the first air guiding plate 31 drives the second air guiding plate 32 to rotate to the first setting position. The first setting position and the horizontal plane form a first setting angle, and the first setting angle can be preset in advance in a factory stage or can be set by a user according to actual requirements in the using process. In addition, in a heating mode, the first setting angle may be preset with a plurality of numerical values so that a user may select the first setting angle.
Step S20: the second air deflector is rotated to a second set position.

In addition, in one heating mode, the second setting angle may be preset with a plurality of numerical values so that the user may select the second setting angle. 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 35 to rotate the second air guiding plate 32 to the closed position relative to the first air guiding plate 31. Preferably, the second set angle is larger than the first set angle, so that the second air deflection plate 32 can open further outwards with respect to the first air deflection plate 31, thereby directing the hot air flow further downwards.
Step S30: the first air guiding plate rotates back and forth within a first set angle range, and the second air guiding plate rotates back and forth within a second set angle range.
The first air deflector motor 33 and the second air deflector motor 35 respectively drive the first air deflector 31 and the second air deflector 32 to rotate back and forth within a first set angle range and a second set angle range.
It is understood that the specific values of the first set angle range and the second set angle range in step S30 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, under a heating mode, the first set angle range and the second set angle range can be set into one group, and multiple groups can be preset so that a user can select the first set angle range and the second set angle range.
As can be seen in connection with fig. 3: the first air deflector 31 is rotated to the first set position to open the air outlet, the second air deflector 32 is rotated to the second set position to open the mounting opening, and compared with a mode of only opening a single air deflector, the arrangement can enable the air outlet area to be large, so that the flow rate of hot air flow is moderate, the effect of soft air supply is achieved, and the user experience is improved. The hot air flow is divided into three hot air flows flowing to different directions by the first air deflector 31 and the second air deflector 32, and the hot air flows are sent to different areas of the indoor space at different angles under the guidance of the respective air deflectors, so that the heating effect is ensured. Subsequently, the flow direction of each air flow is changed by adjusting the rotation angles of the first air deflector 31 and the second air deflector 32, so that the hot air flow can be blown to a plurality of areas of the indoor space, the air supply range is expanded, and the heating effect is ensured.
Through years of research and experiments by the inventor, it is found that the problem of "air passage short circuit" is likely to occur when the rotation angle of the first air guiding plate 31 exceeds 60 ° and the rotation angle of the second air guiding plate 32 exceeds 80 °. Specifically, when the rotation angle of the air guiding plate exceeds 60 ° or the rotation angle of the second air guiding plate 32 exceeds 80 °, the hot air flow sent out by the first air guiding plate 31/the second air guiding plate 32 is easily sucked into the air inlet directly, and cannot participate in the mixing and heating of the indoor air. In view of this, it is preferable that the first set angle is set to 60 ° and the second set angle is set to 80 ° so as to open the first air deflector 31/the second air deflector 32 to the respective maximum angle capable of avoiding the occurrence of the "short circuit of the air passage", and the difference between the initial opening angles of the two air deflectors also helps to reduce the possibility that the two air deflectors rotate synchronously under the driving of the respective motors, so that the two air deflectors can have different blowing angles, and thus hot air can be blown to different areas of the indoor space. The first set angle range of the first air deflector 31 is 10 degrees to 60 degrees, and the second set angle of the second air deflector 32 is 0 degrees to 80 degrees, so that the air supply range is expanded as much as possible on the premise of avoiding the occurrence of 'air path short circuit', the hot air flow can be blown to each indoor area as much as possible, and the temperature uniformity of the indoor environment is ensured.
As a specific example, in the case that the air conditioner receives a soft heating mode command, the controller controls the first air guiding plate motor 33 to operate to drive the first air guiding plate 31 to open to a position 60 ° away from the horizontal plane, and then to rotate back and forth within an angle range of 10-60 °; meanwhile, the second air deflector motor is controlled to operate to drive the second air deflector motor 35 to rotate to a position which forms an angle of 80 degrees with the horizontal plane, then the second air deflector motor swings in a range of 0-80 degrees, the air outlet 111 and the mounting port 3111 are opened at the moment, heating air supply is softer due to the increase of the air outlet area, a plurality of hot air flows are formed by the hot air from the air outlet and are respectively sent out by the first air deflector 31 and the second air deflector 32 at different angles, and the air supply direction can be changed by the first air deflector 31 and the second air deflector 32 which rotate back and forth, so that the air supply range is expanded.
It should be noted that, although the above example is described in the order of opening the first air guiding plate 31 and then opening the second air guiding plate 32, in practical applications, the second air guiding plate 32 and then opening the first air guiding plate 31 may be opened, or both air guiding plates may be opened at the same time. Similarly, the sequence of the rotation of the first air guiding plate 31 and the second air guiding plate 32 is not limited to the above example, for example, when the first air guiding plate 31 is opened and the second air guiding plate 32 is not opened, the first air guiding plate 31 may be rotated back and forth, and then the second air guiding plate 32 may be opened to rotate the second air guiding plate 32 back and forth. The opening sequence and the back-and-forth rotation sequence of the first air deflector 31 and the second air deflector 32 can be flexibly set by those skilled in the art according to actual requirements.
In summary, in the embedded air conditioner of the present invention, the first air guide plate 31 is provided with the installation opening 3111, the second air guide plate 32 is embedded in the installation opening 3111, and the second air guide plate 32 is rotated to split and guide the airflow, so as to expand the air supply range. And the embedded design can ensure the external flatness of the air deflector 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 independently rotate respectively to form various air supply forms, so that more various air supply requirements of users are met, and user experience is improved. The air deflector control method for heating the air conditioner of the invention opens the first air deflector 31 and the second air deflector 32 simultaneously to increase the air outlet area under the heating condition, so that the flow rate of hot air flow is reduced, thereby realizing the soft air supply effect.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
