Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an indoor unit and an air conditioner. Background Technology

[0002] Wall-mounted air conditioners are widely used. Since the indoor unit of a wall-mounted air conditioner is usually installed in a fixed position, it is necessary to supply air to different areas of the room in order to make the indoor temperature uniform. Usually, an air guide plate is installed at the air outlet of the indoor unit of the wall-mounted air conditioner, and the air is guided by the swing of the air guide plate.

[0003] When an air conditioner is running in cooling mode, a baffle is installed in the middle frame to prevent cold air from blowing directly out. The baffle can be adjusted to move on the middle frame to change its obstruction of the airflow from the air outlet to the indoor environment, thereby improving the user experience.

[0004] However, the relevant technology has at least one of the following problems: the wind deflector in the existing air conditioner is located on the front side of the panel, which can limit the airflow from the air outlet to the front, but cannot limit the lateral airflow at both ends along the length of the air conditioner, resulting in poor wind deflection effect and reduced user experience. Summary of the Invention

[0005] The technical problem solved by this invention is that the wind deflector in existing air conditioners is located on the front side of the panel. Although it can limit the airflow from the air outlet to the front, it cannot limit the lateral airflow at both ends along the length of the air conditioner, resulting in poor wind deflection and reduced user experience.

[0006] To address the aforementioned problems, the present invention provides an indoor unit, comprising: a middle frame housing with an air outlet at its bottom end; a first wind deflector movably connected to the front end face of the middle frame housing to move toward or away from the air outlet; and a second wind deflector movably connected to the side end face of the middle frame housing to extend or retract toward the air outlet; wherein the direction of airflow from the air outlet is changed by adjusting the position of the first and / or second wind deflectors relative to the air outlet.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: When the first baffle is adjusted to face closer to the air outlet, at least a portion of its structure extends out of the middle frame housing, placing it within the air outlet path that guides the airflow into the indoor environment. This shortens the air outlet distance from the front of the indoor unit, effectively preventing direct cold air from blowing from the front. Furthermore, when at least a portion of the second baffle extends out of the middle frame housing, it acts as a lateral stop for the airflow. Combined with the actual installation of the wall-mounted indoor unit, the area of ​​cold air blown from the air outlet is effectively limited to the air outlet range bounded by the wall, the first baffle, and the second baffle. This reduces the heat exchange efficiency between the air outlet and areas outside the aforementioned air outlet range, significantly reducing the wind force within the air outlet range and improving the windless experience for users outside this range.

[0008] In one embodiment of the present invention, when the indoor unit is in a first state, the first wind deflector and the second wind deflector are arranged around the air outlet so that the air outlet direction is toward the wall-mounted side of the indoor unit and / or toward vertically downward; and / or, when the indoor unit is in a second state, the first wind deflector and the second wind deflector are exposed at the air outlet.

[0009] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: through the coordinated operation of the first and second wind deflectors, the airflow from the indoor unit in the front and lateral directions can be effectively blocked, thus further improving the effect of preventing cold air from blowing directly on the unit compared to a single wind deflector.

[0010] In one embodiment of the present invention, the first windshield and / or the second windshield are slidably connected to the middle frame housing.

[0011] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: For example, the first windshield and the second windshield are slidably connected to the middle frame housing, making it more convenient and easier to move the first windshield and the second windshield.

[0012] In one embodiment of the present invention, the present invention includes: a slide rail assembly disposed on the middle frame housing for cooperating with the first wind deflector and the second wind deflector to restrict their disengagement from the middle frame housing; and a drive assembly mounted on the middle frame housing for clamping the first wind deflector and the second wind deflector together with the slide rail assembly; wherein the drive assembly drives the first wind deflector and the second wind deflector to move on the middle frame housing respectively.

[0013] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: On the one hand, by driving the first and second wind deflectors to move on the middle frame housing through the drive component, manual adjustment is replaced, improving the adjustment efficiency of the movement of the two components and enhancing the user experience; on the other hand, by shielding the drive component through the first and second wind deflectors, the drive component is effectively prevented from being exposed to the user's line of sight, thus reducing the aesthetic appearance of the indoor unit, while making the indoor unit look more concise.

[0014] In one embodiment of the present invention, the drive assembly includes a first drive motor disposed on the front end face and a first transmission gear cooperating with the first drive motor, at least a portion of the structure of the first transmission gear extending out of a first mounting opening disposed on the surface of the middle frame housing; a first windshield member is provided with a first meshing rack meshing with the first transmission gear on the side near the first transmission gear; and / or, the drive assembly includes a second drive motor disposed on the side end face and a second transmission gear cooperating with the second drive motor, at least a portion of the structure of the second transmission gear extending out of a second mounting opening disposed on the surface of the middle frame housing; a second windshield member is provided with a second meshing rack meshing with the second transmission gear on the side near the second transmission gear.

[0015] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: by moving the first windshield by meshing the first transmission gear and the first rack, and by moving the second windshield by meshing the second transmission gear and the second rack, the stability of movement is improved, slippage during transmission is effectively avoided, and the noise generated by both during movement is reduced.

[0016] In one embodiment of the present invention, the slide rail assembly includes a first slide rail disposed on the front end face and a second slide rail disposed on the side end face, a first wind deflector cooperating with the first slide rail, and a second wind deflector cooperating with the second slide rail; a first pulley group is provided on the side of the first slide rail near the first wind deflector, and / or a second pulley group is provided on the side of the second slide rail near the second wind deflector.

[0017] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: Specifically, by setting up the first pulley group and the second pulley group, the friction noise generated by the first and second windshields pressing against the first and second slide rails respectively in a surface-to-surface cooperation manner is effectively avoided, thereby further improving the user experience and ensuring that the first and second windshields remain relatively quiet during movement.

[0018] In one embodiment of the invention, the slide rail trajectory of the slide rail assembly is adapted to the corresponding surface curve of the middle frame housing.

[0019] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: On the one hand, it reduces the distance between the first and second wind deflectors and the middle frame shell caused by excessive deviation between the trajectory of the slide rail assembly and the surface curve of the middle frame shell, which would otherwise increase the space occupancy of the indoor unit; on the other hand, it minimizes the change in the appearance of the indoor unit during the movement of the first and second wind deflectors, effectively maintaining the aesthetic appearance of the indoor unit.

[0020] In one embodiment of the present invention, an air inlet is provided at the top of the middle frame housing; the middle frame housing further includes: a third slide rail, which is arranged at the top and cooperates with the first slide rail to allow the first wind deflector to slide between the two; wherein, when the first wind deflector slides to the third slide rail, the first wind deflector covers the air inlet.

[0021] Compared with existing technologies, the technical effect achieved by adopting this technical solution is as follows: by sealing the air inlet with the first wind deflector, dust is prevented from entering the air inlet when the indoor unit is in standby mode.

[0022] In one embodiment of the present invention, it further includes: a controller, which is communicatively connected to the drive assembly to control the drive assembly to move the first windshield and the second windshield on the middle frame housing, respectively.

[0023] Compared with the existing technology, the technical effect achieved by adopting this technical solution is that it allows users to remotely adjust the positions of the first windshield and the second windshield by controlling the first drive motor and the second drive motor respectively.

[0024] On the other hand, the present invention also provides an air conditioner, including an indoor unit as in any of the above examples.

[0025] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: it can achieve the corresponding technical effects as in any of the above technical solutions, which will not be elaborated here.

[0026] By adopting the technical solution of the present invention, the following technical effects can be achieved:

[0027] (1) When the first wind deflector is adjusted to face the air outlet, at least a portion of its structure extends out of the middle frame housing, placing it in the air outlet path that guides the airflow into the indoor environment. This shortens the air outlet distance of the indoor unit from the front, effectively preventing direct cold air from blowing from the front. Furthermore, when at least a portion of the second wind deflector extends out of the middle frame housing, it acts as a stop for the airflow direction in the lateral direction. Combined with the actual installation of the wall-mounted indoor unit, the air outlet area of ​​the cold air blown out of the air outlet is effectively limited to the air outlet range bounded by the wall, the first wind deflector, and the second wind deflector. This reduces the heat exchange efficiency between the air outlet and the area outside the aforementioned air outlet range, significantly reducing the wind force within the air outlet range and improving the windless experience for users outside this range.

[0028] (2) On the one hand, the first and second wind deflectors are driven to move on the middle frame housing by the drive component, which replaces manual adjustment, improves the adjustment efficiency of adjusting the movement of the two components, and improves the user experience; on the other hand, the first and second wind deflectors effectively prevent the drive component from being exposed to the user's line of sight and reduce the aesthetic appearance of the indoor unit, while making the indoor unit look simpler.

[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] See Figure 1 This is a structural schematic diagram of an indoor unit 100 provided in an embodiment of the present invention. Combined with... Figures 2-8 The indoor unit 100 includes, for example, a middle frame housing 10, a first wind deflector 20, and a second wind deflector 30. The bottom end of the middle frame housing 10 is provided with an air outlet 11; the first wind deflector 20 is movably connected to the front end face 12 of the middle frame housing 10 to move towards or away from the air outlet 11; the second wind deflector 30 is movably connected to the side end face 13 of the middle frame housing 10 to extend or retract towards the air outlet 11; wherein, the direction of airflow from the air outlet 11 is changed by adjusting the position of the first wind deflector 20 and / or the second wind deflector 30 relative to the air outlet 11.

[0041] Understandably, the traditional indoor unit 100 has an air inlet 14 at its top and an air outlet 11 at its bottom. Furthermore, in order to adjust the direction of the air blown out from the air outlet 11, a guide vane is set at the position of the air outlet 11 to achieve the effect of adjusting the air outlet direction. When the indoor unit 100 is turned off, the guide vane automatically closes the air outlet 11.

[0042] However, considering the actual assembly of the air guide plate and the middle frame housing 10, while changing the air outlet direction, it cannot effectively prevent the direct blowing of cold air.

[0043] Specifically, by setting a wind deflector in the middle frame, the obstruction effect on the cold air blown from the air outlet 11 to the indoor environment can be changed by adjusting the movement of the wind deflector on the middle frame. However, the wind deflector in existing air conditioners is only set on the front side of the panel. Although it can limit the airflow from the air outlet 11 in the forward direction, it cannot limit the lateral airflow at both ends along the length of the air conditioner, resulting in poor wind blocking effect and reduced user experience.

[0044] Therefore, in conjunction with the content of this technical solution, by setting multiple wind deflectors at different parts of the middle frame housing 10, such as setting the first wind deflector 20 on the front end face 12 and the second wind deflector 30 on the side end face 13, the direction of the air blown out from the air outlet 11 can be limited. Specifically, when the position of the first wind deflector 20 is adjusted to be closer to the air outlet 11, so that at least a part of the structure of the first wind deflector 20 extends out of the middle frame housing 10, it is placed in the air outlet path of the air guide plate that guides the air out to the indoor environment, thereby shortening the air outlet distance of the indoor unit 100 from the front, that is, preventing cold air from blowing directly from the front.

[0045] Furthermore, when the second baffle 30 is adjusted to extend towards the air outlet 11, similar to the principle described above, at least a portion of the structure of the second baffle 30 extends out of the middle frame housing 10. It is understood that the direction of the cold air blown out of the indoor unit 100 is affected by the sweeping blades located inside it. In conventional air conditioners, the sweeping blades adjust the airflow direction in the lateral direction, which can be understood as the direction of the line connecting the two oppositely arranged side end faces 13 of the middle frame housing 10.

[0046] Therefore, when at least a portion of the structure of the second baffle 30 extends out of the middle frame housing 10, it can act as a stop for the airflow direction in the lateral direction. Combined with the actual installation of the wall-mounted indoor unit 100, the airflow area of ​​the cold air blown out from the air outlet 11 is effectively limited to the airflow range bounded by the wall, the first baffle 20, and the second baffle 30. This reduces the heat exchange efficiency between the air outlet 11 and the area outside the aforementioned airflow range, meaning the wind force within the airflow range is significantly reduced, thereby improving the windless experience for users outside this airflow range.

[0047] Furthermore, in a specific example, the first wind deflector 20 is a first wind deflector plate, and the second wind deflector 30 is a second wind deflector plate. For example, the first wind deflector plate can be extended only from the middle frame housing 10, thereby only achieving the wind deflection effect on the front side of the indoor unit 100. In contrast, the second wind deflector plate can be extended only from the middle frame housing 10, thereby only achieving the wind deflection effect on the lateral side of the indoor unit 100.

[0048] Of course, based on the above, the extension length of the first wind deflector 20 and the second wind deflector 30 extending out of the middle frame housing 10 can be adjusted. This lengthens the air outlet duct formed by the combination of the first wind deflector 20 and the second wind deflector 30, allowing the cold air from the air outlet 11 to reach the floor of the indoor environment more quickly. This reduces the heat exchange efficiency between the indoor unit 100 and the indoor environment, except for the air outlet duct, thus slowing down the heat exchange and preventing the user from feeling uncomfortable due to an excessively fast heat exchange rate.

[0049] It should be noted that the front end face 12 of the mid-frame housing 10 mentioned in this technical solution is oriented towards the user, for example, referred to as the user side 102. Opposite to the user side 102 is the wall-mounted side 101, which is the side closest to the wall. A mounting plate is installed on the wall-mounted side 101 to facilitate the installation of the indoor unit 100 onto the wall. Therefore, the aforementioned function of preventing direct cold air from the front specifically means that cold air is directed directly towards the user side 102.

[0050] Preferably, when the indoor unit 100 is in the first state, the first wind deflector 20 and the second wind deflector 30 are arranged around the air outlet 11 so that the air outlet direction is towards the wall-mounted side 101 of the indoor unit 100 and / or vertically downward; and / or, when the indoor unit 100 is in the second state, the first wind deflector 20 and the second wind deflector 30 are exposed outside the air outlet 11. The coordinated operation of the first wind deflector 20 and the second wind deflector 30 effectively blocks the airflow from the indoor unit 100 in the front and lateral directions, thus further improving the effect of preventing direct cold air blowing compared to a single wind deflector.

[0051] Preferably, the first wind deflector 20 and / or the second wind deflector 30 are slidably connected to the middle frame housing 10. For example, the first wind deflector 20 and the second wind deflector 30 are slidably connected to the middle frame housing 10, making it more convenient and easier to move the first wind deflector 20 and the second wind deflector 30.

[0052] Preferably, the indoor unit 100 includes, for example, a slide rail assembly and a drive assembly. The slide rail assembly is disposed on the middle frame housing 10 and is used to cooperate with the first wind deflector 20 and the second wind deflector 30 to prevent them from dislodging from the middle frame housing 10; the drive assembly is mounted to the middle frame housing 10 and, together with the slide rail assembly, clamps the first wind deflector 20 and the second wind deflector 30; wherein, the drive assembly drives the first wind deflector 20 and the second wind deflector 30 to move on the middle frame housing 10.

[0053] On the one hand, the drive component drives the first wind deflector 20 and the second wind deflector 30 to move on the middle frame housing 10, replacing manual adjustment, improving the adjustment efficiency of adjusting the movement of the two components, and enhancing the user experience; on the other hand, the shielding effect of the first wind deflector 20 and the second wind deflector 30 on the drive component effectively prevents the drive component from being exposed to the user's line of sight and reducing the aesthetic appearance of the indoor unit 100, while making the indoor unit 100 look more concise.

[0054] Preferably, the drive assembly includes a first drive motor 511 disposed on the front end face 12 and a first transmission gear 512 cooperating with the first drive motor 511. At least a portion of the structure of the first transmission gear 512 extends out of the first mounting opening 121 disposed on the surface of the middle frame housing 10. The first windshield 20 is provided with a first meshing rack 21 meshing with the first transmission gear 512 on the side near the first windshield 20.

[0055] Alternatively, the drive assembly includes a second drive motor 521 disposed on the side end face 13 and a second transmission gear 522 cooperating with the second drive motor 521. At least a portion of the structure of the second transmission gear 522 extends out of the second mounting opening 131 disposed on the surface of the middle frame housing 10. The second windshield 30 is provided with a second meshing rack 31 meshing with the second transmission gear 522 on the side near the second windshield 30.

[0056] The stability of movement is improved by moving the first windshield 20 by engaging the first transmission gear 512 and the first rack, and by moving the second windshield 30 by engaging the second transmission gear 522 and the second rack. This effectively avoids slippage during transmission and reduces the noise generated during movement.

[0057] Preferably, the slide rail assembly includes a first slide rail 41 disposed on the front end face 12 and a second slide rail 42 disposed on the side end face 13. The first wind deflector 20 cooperates with the first slide rail 41, and the second wind deflector 30 cooperates with the second slide rail 42. The first slide rail 41 is provided with a first pulley group on the side near the first wind deflector 20, and / or the second slide rail 42 is provided with a second pulley group on the side near the second wind deflector 30.

[0058] Specifically, by setting up the first pulley group and the second pulley group, the friction noise generated by the first windshield 20 and the second windshield 30 pressing against the first slide rail 41 and the second slide rail 42 respectively in a surface-to-surface cooperation manner is effectively avoided, thereby further improving the user experience and ensuring that the first windshield 20 and the second windshield 30 remain relatively quiet during movement.

[0059] Preferably, the slide rail trajectory of the slide rail assembly is adapted to the corresponding surface curve of the middle frame housing 10. On the one hand, this reduces the problem of excessive deviation between the slide rail assembly trajectory and the surface curve of the middle frame housing 10, which would cause changes in the distance between the first and second wind deflectors 20 and the middle frame housing 10 during movement, thus preventing an increase in the space occupancy of the indoor unit 100. On the other hand, this ensures that the appearance of the indoor unit 100 changes less during the movement of the first and second wind deflectors 20 and 30, effectively maintaining the aesthetic appearance of the indoor unit 100.

[0060] Preferably, an air inlet 14 is provided at the top of the middle frame housing 10; the middle frame housing 10 further includes a third slide rail, which extends to the top and cooperates with the first slide rail 41 to allow the first wind deflector 20 to slide between them; wherein, when the first wind deflector 20 slides to the third slide rail, the first wind deflector 20 covers the air inlet 14. By covering the air inlet 14 with the first wind deflector 20, it is ensured that dust is prevented from entering the air inlet 14 when the indoor unit 100 is in standby mode.

[0061] Preferably, the indoor unit 100 also includes a controller. The controller is communicatively connected to the drive assembly to control the drive assembly to move the first wind deflector 20 and the second wind deflector 30 respectively on the mid-frame housing 10. This allows the user to remotely adjust the positions of the first wind deflector 20 and the second wind deflector 30 via the controller's first drive motor 511 and the second drive motor 521. For example, the controller can be a remote control or an app application stored on a mobile device, such as a mobile phone.

[0062] On the other hand, embodiments of the present invention also provide an air conditioner. Specifically, the air conditioner includes, for example, the indoor unit 100 as described in any of the above technical solutions. Correspondingly, this embodiment can achieve the corresponding technical effects of any of the above technical solutions, which will not be elaborated here.

[0063] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
