Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to a vertical air conditioner. Background Technology

[0002] With the development of related technologies in the air conditioning field, air conditioning products are also constantly being updated and replaced. From the evolution of air conditioning models, the earliest air conditioning model was the integrated window air conditioner. Now, the mainstream model is the split air conditioner. Floor-standing air conditioners and wall-mounted air conditioners are two important branches of today's split air conditioners. As the name suggests, a floor-standing air conditioner is an air conditioner with an indoor unit in the shape of a column and installed on the ground, while a wall-mounted air conditioner is an air conditioner with an indoor unit suspended on the wall by components such as a back panel bracket.

[0003] In related technologies, vertical air conditioner indoor units are usually equipped with a sliding door that slides in the left and right direction at the air outlet. When the vertical air conditioner indoor unit is not working, the sliding door is driven by a moving mechanism to block the air outlet, thereby preventing dust from entering the interior of the vertical air conditioner indoor unit through the air outlet.

[0004] However, because the width of the indoor unit of a vertical air conditioner in the relevant technology is usually relatively small in the left and right directions, the space on the left and right sides of the sliding door is relatively limited, resulting in a narrow sliding range of the sliding door. Consequently, the width of the sliding door in the left and right directions is also relatively narrow, making it difficult for the indoor unit of the vertical air conditioner to quickly change the air temperature over a large area of ​​the room, resulting in a poor user experience. Summary of the Invention

[0005] This application discloses a vertical air conditioner that can ensure the sliding door's sliding stroke to form a large first air outlet without increasing the width of the casing in the width direction.

[0048] The vertical air conditioner provided in this application embodiment, by controlling the width of the first air outlet on the casing to be greater than or equal to half the width of the casing, allows the vertical air conditioner in this application to have a relatively large air outlet, thereby increasing the air volume of the vertical air conditioner, resulting in an increase in cooling or heating capacity, and thus enabling the vertical air conditioner to quickly change the air temperature over a larger range indoors, improving the user's experience.

[0049] Based on this, this application further redesigns the position of the drive device, placing it at the top and / or bottom of the sliding door in the height direction. This allows the sliding door and the first air outlet to overlap at least partially in the height direction, creating a larger gap between the sliding door and other components within the casing, such as the heat exchanger. This provides the sliding door with greater sliding space to cover a wider first air outlet. Consequently, without increasing the width of the casing, a relatively wide first air outlet and sliding door are formed, increasing the air volume of the vertical air conditioner and thus improving cooling or heating capacity. This allows the vertical air conditioner to quickly change the air temperature over a larger area of ​​the room, enhancing the user experience. Simultaneously, it avoids interference between the drive device and other components within the casing (such as the heat exchanger), ensuring that the sliding door can smoothly open or close the first air outlet.

[0078] To make the objectives, technical solutions, and advantages of this application clearer, the exemplary embodiments of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments. That is, the specific embodiments described herein are merely used to explain this application and are not intended to limit this application.

[0079] It should be noted that the brief descriptions of terminology used in this application are merely for the purpose of facilitating understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit this application.

[0080] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0081] The terms "first," "second," etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this application, a first air outlet may be referred to as a second air outlet, and similarly, a second air outlet may be referred to as a first air outlet. Both the first air outlet and the second air outlet are air outlets, but they are not the same air outlet.

[0082] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0083] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0084] In the description of this application, it should be noted that the singular forms of "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that terms such as "comprising / including" or "having" specify the presence of the stated features, integrals, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integrals, steps, operations, components, parts, or combinations thereof.

[0085] In addition, the term "and / or" as used in this specification includes any and all combinations of the related listed items. For example, A and / or B can mean: A alone, A and B together, or B alone. That is, the term "and / or" as used in this specification includes any and all combinations of the related listed items.

[0086] In order to prevent dust from entering the interior of the indoor unit through the air outlet of the indoor unit when the indoor unit is not working, a sliding door that can slide relative to the air outlet is usually installed at the air outlet. When the indoor unit is not working, the sliding door can be driven by a drive device to slide and block the air outlet.

[0087] With the development of vertical air conditioning technology, users have gradually increased their requirements for the air volume of vertical air conditioners. For example, they hope that the casing of the indoor unit can form a relatively wide air outlet to have the advantage of large air volume, thereby bringing an increase in cooling or heating, and thus quickly changing the air temperature over a large area of ​​the room, providing users with a better user experience.

[0088] Because floor-standing air conditioners are named for their indoor units being column-shaped and placed on the ground, the height of the indoor unit is usually about the same as human height to ensure the cooling effect. Therefore, to achieve a smaller indoor unit design for easier transport, the width of the indoor unit is usually reduced.

[0089] However, as the indoor units of vertical air conditioners become smaller, that is, as the width of the casing in its width direction becomes smaller, the width of the air outlet on the casing also becomes smaller, thus failing to meet user requirements.

[0090] Moreover, the drive unit in the relevant technology is usually located on the left or right side of the indoor unit in the width direction, which must occupy the internal space of the casing in the width direction and is not conducive to increasing the width of the air outlet.

[0091] Through experiments, the researchers of this application discovered that when the width of the air outlet increases, without increasing the width of the casing, the drive device will get closer and closer to other components inside the casing, especially the heat exchanger. This causes the drive device to be blocked by the heat exchanger during the sliding process, resulting in a limited sliding stroke of the sliding door, which cannot fully open the air outlet. Thus, even if a large air outlet is formed, the air volume cannot be increased, let alone the cooling capacity, and therefore the indoor air temperature cannot be changed quickly over a large area.

[0092] While responding to the design of a large air outlet, the developers of this application noticed that without increasing the width of the casing, the drive device would interfere with other components inside the casing, especially the heat exchanger. Therefore, while maintaining a compact casing design and forming a large air outlet, the developers further redesigned the position of the drive device, placing it at the top and / or bottom of the sliding door in the height direction. This allows the sliding door to have a larger gap between itself and other components inside the casing, such as the heat exchanger, in its sliding direction. This provides the sliding door with more sliding space to cover the wider air outlet and also avoids interference between the drive device and other components inside the casing, ensuring that the sliding door can open or close the air outlet smoothly.

[0093] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0094] This application discloses a vertical air conditioner that primarily performs a refrigeration cycle using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, supplying refrigerant to the conditioned and heat-exchanged air.

[0095] The compressor compresses refrigerant gas under high temperature and pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0096] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0097] The vertical air conditioner in this application includes an indoor unit and an outdoor unit, with the indoor unit connected to the outdoor unit installed in the outdoor space via pipes.

[0098] The outdoor unit may contain a compressor, an outdoor heat exchanger, an outdoor fan, an expander, and similar functional components for the refrigeration cycle. The indoor unit may also contain an indoor heat exchanger and an indoor fan. The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the floor-standing air conditioner functions as a heater in heating mode; when it is used as an evaporator, it functions as a cooler in cooling mode.

[0099] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a vertical air conditioner indoor unit provided in an embodiment of this application. This application discloses a vertical air conditioner, which includes an indoor unit 100 and an outdoor unit (not shown). The indoor unit 100 is connected to the outdoor unit installed in the outdoor space via a pipe.

[0100] Please see Figure 1 The indoor unit 100 provided in this application embodiment includes a housing 10; the housing 10 may be a columnar structure, such as a circular columnar structure, a square columnar structure, etc., and the housing 10 has a length direction f1, a width direction f2 and a height direction f3.

[0101] like Figure 1 As shown, the housing 10 has a top and a bottom, and the distance from the top to the bottom of the housing 10 is the height direction f3 of the housing 10; the housing 10 also has a left side and a right side that are arranged opposite to each other, and the distance from the left side to the right side of the housing 10 is the width direction f2 of the housing 10; the housing 10 also has a front side and a rear side that are arranged opposite to each other, and the side of the housing 10 facing the user is the front side of the housing 10, and the distance from the front side to the rear side of the housing 10 is the length direction f1 of the housing 10.

[0102] In some embodiments, such as Figure 2 and Figure 3 As shown, the housing 10 has an inner cavity 11; the inner cavity 11 can be used to accommodate various functional components of the vertical indoor air conditioner, such as the volute 20, fan and heat exchanger mentioned later.

[0103] In some embodiments, such as Figures 1 to 3 As shown, the housing 10 has a first air outlet 12 and an air inlet (hereinafter referred to as the indoor air inlet 13). The first air outlet 12 and the indoor air inlet 13 are connected to the inner cavity 11. The first air outlet 12 is located on the front side of the housing 10, and the indoor air inlet 13 is located on the rear side of the housing 10.

[0104] In some embodiments, the indoor unit 100 includes a volute 20 disposed in the inner cavity 11, and the volute 20 has an air duct 21 that communicates with the first air outlet 12 and the indoor air inlet 13 respectively.

[0105] In some embodiments, the indoor unit 100 includes a heat exchanger (not shown, hereinafter referred to as the indoor heat exchanger), which is disposed in the inner cavity 11 and is used to exchange heat with the air entering the inner cavity 11.

[0106] In some embodiments, the indoor unit 100 includes a fan (not shown, hereinafter referred to as an indoor fan), which is disposed in the inner cavity 11 and at least partially disposed in the air duct 21. The indoor fan is located in front of the indoor heat exchanger and is used to provide power for the flow of air.

[0107] Driven by the heat exchange fan, air enters the inner cavity 11 through the indoor air inlet 13 to exchange heat with the indoor heat exchanger. The air after heat exchange with the indoor heat exchanger, such as cooled cold air or heated hot air, enters the air duct 21 under the action of the indoor fan and is blown into the indoor space through the first air outlet 12 to change the air temperature of the indoor space, such as lowering the air temperature of the indoor space or raising the air temperature of the indoor space.

[0108] In some embodiments, the outdoor unit includes an outdoor unit housing, an outdoor heat exchanger, and an outdoor fan.

[0109] In some embodiments, an outdoor housing is provided inside the outdoor unit casing, wherein the outdoor fan and the outdoor heat exchanger are located within the outdoor housing.

[0110] In some embodiments, the outdoor unit casing is provided with an outdoor air inlet and an outdoor air outlet, both of which are connected to the outdoor housing space. The outdoor air inlet is used to introduce outdoor air into the outdoor housing space, and the outdoor air outlet is used to exhaust air from the outdoor housing space to the outside of the outdoor housing space.

[0111] In some embodiments, the rotation of the outdoor fan causes outdoor air to enter the outdoor containment space through the outdoor air inlet and exchange heat with the outdoor heat exchanger. The outdoor air after heat exchange flows out of the outdoor containment space through the outdoor air outlet.

[0112] In some embodiments, the outdoor unit further includes a compressor and a throttling device, both of which are located within the outdoor housing space.

[0113] In some embodiments, a floor-standing air conditioner performs a refrigeration cycle using a compressor, a condenser, a throttling device, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0114] In some embodiments, the compressor compresses the refrigerant gas in a low-temperature, low-pressure state and discharges it into a high-temperature, high-pressure state. The discharged refrigerant gas flows into the condenser.

[0115] In some embodiments, the condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0116] In some embodiments, the throttling device causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant.

[0117] In some embodiments, the evaporator evaporates the refrigerant that expands in the throttling device and returns the refrigerant gas, which is in a low-temperature and low-pressure state, to the compressor.

[0118] In some embodiments, the evaporator achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material to be cooled. Throughout the cycle, the vertical unit can regulate the temperature of the indoor space.

[0119] In some embodiments, of the indoor heat exchanger and the outdoor heat exchanger, one is a condenser and the other is an evaporator. When the indoor heat exchanger is used as a condenser, the floor-standing air conditioner is used as a heater in heating mode, and when the indoor heat exchanger is used as an evaporator, the floor-standing air conditioner is used as a cooler in cooling mode.

[0120] In this application, as Figure 3 As shown, for ease of description, the width of the housing 10 in its width direction f2 is defined as w0, and the width of the first air outlet 12 in the width direction f2 of the housing 10 is defined as w1. It is understood that the above definitions are merely for the convenience of this application's description, and should not be used to limit the scope of protection of this application.

[0121] If w1 < w0 / 2, the width of the first air outlet 12 is too small, resulting in a small air volume. This makes it difficult for the indoor unit 100 to quickly change the air temperature over a large area, which may lead to a poor user experience.

[0122] In some embodiments, w1≥w0 / 2, thereby ensuring that the indoor unit 100 in this application has a relatively large first air outlet 12, so that the air volume of the indoor unit 100 can be increased, thereby bringing an increase in cooling or heating, and thus enabling the indoor unit 100 to quickly change the air temperature over a large range of indoor areas, improving the user experience.

[0123] If w1 > 7w0 / 8, the internal installation space of the housing 10 in the width direction f2 will be reduced, which is not conducive to the arrangement of various functional components of the indoor unit 100 in the inner cavity 11 of the housing 10.

[0124] In some embodiments, w1≤7w0 / 8. This configuration allows the indoor unit 100 to have a relatively large air outlet and also facilitates the arrangement of various functional components of the indoor unit 100 within the inner cavity 11 of the housing 10.

[0125] In some embodiments, w0 / 2 ≤ w1 ≤ 7w0 / 8, for example, w0 / 2 ≤ w1 ≤ 5w0 / 8, 5w0 / 8 ≤ w1 ≤ 3w0 / 4, or 3w0 / 4 ≤ w1 ≤ 7w0 / 8. Exemplary examples include w1 = w0 / 2, 9w0 / 16, 5w0 / 8, 11w0 / 16, 3w0 / 4, 13w0 / 16, or 7w0 / 8, etc.

[0126] This configuration allows the indoor unit 100 to have a sufficiently large first air outlet 12, thereby increasing the air volume of the indoor unit 100 and quickly changing the air temperature over a larger range of indoor areas. It also avoids excessive reduction of the inner cavity 11 of the housing 10, which would affect the installation and arrangement of various functional components in the inner cavity 11, while achieving a miniaturized design. This facilitates the arrangement and setting of various functional components in the inner cavity 11 of the housing 10.

[0127] In some embodiments, the volute 20 is provided with a second air outlet 22, and the air duct 21 is connected to the first air outlet 12 through the second air outlet 22. Thus, when the indoor unit 100 is running, the air that has been heated by the heat exchanger, such as cooled air, enters the air duct 21 under the action of the fan, and enters the first air outlet 12 through the second air outlet 22, and finally is blown into the indoor space from the first air outlet 12 to change the air temperature of the indoor space, such as lowering the air temperature of the indoor space.

[0128] In this application, for ease of description, the width of the second air outlet 22 in the width direction f2 of the housing 10 is defined as w2. It is understood that the above definition is only for the convenience of the description of this application, but should not be used to limit the scope of protection of this application.

[0129] If w2 < 2w0 / 5, the width of the second air outlet 22 is too small, which will restrict the airflow and weaken the cooling or heating effect of the indoor unit 100. This may affect the heat dissipation efficiency and overall performance of the indoor unit 100, preventing the heat exchanger of the indoor unit 100 from fully functioning and potentially affecting the service life of the indoor unit 100.

[0130] In some embodiments, w2≥2w0 / 5, which ensures that the indoor unit 100 has a large air volume, thereby accelerating the change speed of the indoor air temperature by the indoor unit 100 and improving the user experience.

[0131] If w2 > 3w0 / 5, the excessive width of the second air outlet 22 may cause the airflow to be too dispersed, resulting in the indoor unit 100's cooling or heating effect being less than expected.

[0132] In some embodiments, w2 ≤ 3w0 / 5. This configuration allows the second air outlet 22 to provide a larger airflow, improving indoor air circulation and making the indoor air fresher, which is beneficial to improving indoor air quality; it also reduces energy consumption and noise.

[0133] In some embodiments, 2w0 / 5 ≤ w2 ≤ 3w0 / 5, for example, 2w0 / 5 ≤ w2 ≤ 9w0 / 20, 9w0 / 20 ≤ w2 ≤ w0 / 2, w0 / 2 ≤ w2 ≤ 11w0 / 20, or 11w0 / 20 ≤ w2 ≤ 3w0 / 5. For example, w2 = 2w0 / 5, 17w0 / 40, 9w0 / 20, 19w0 / 40, w0 / 2, 11w0 / 20, 23w0 / 40, or 3w0 / 5, etc.

[0134] This configuration increases the air volume while preventing excessive airflow dispersion, thus ensuring the cooling or heating effect of the indoor unit 100; it also reduces energy consumption and noise.

[0135] In some embodiments, such as Figure 4 As shown, the indoor unit 100 includes a sliding door 30; the sliding door 30 is located at the first air outlet 12, and the sliding door 30 is used to slide open or close the first air outlet 12.

[0136] That is, when the indoor unit 100 is running, the sliding door 30 can open the first air outlet 12, so that the first air outlet 12 is no longer blocked by the sliding door 30, allowing the indoor unit 100 to blow air into the room; when the indoor unit 100 is not running, the sliding door 30 can close the first air outlet 12, so that the first air outlet 12 is blocked by the sliding door 30 to prevent dust from entering the interior of the indoor unit 100 through the first air outlet 12.

[0137] In some embodiments, such as Figure 4 As shown, the indoor unit 100 includes a drive device 40, which is disposed in the inner cavity of the housing 10 and is connected to the sliding door 30 so that the drive device 40 can be used to drive the sliding door 30 to slide, thereby realizing the opening and closing of the sliding door 30 to the first air outlet 12.

[0138] In some embodiments, the drive device 40 is located at the top and / or bottom of the sliding door 30 in the height direction f3 of the housing 10. That is, the drive device 40 may be located at the top of the sliding door 30 in the height direction f3 of the housing 10, or at the bottom of the sliding door 30 in the height direction f3 of the housing 10. Alternatively, the drive device 40 may include a first drive mechanism 40a and a second drive mechanism 40b. The first drive mechanism 40a is located at the top of the sliding door 30 in the height direction f3 of the housing 10, and the second drive mechanism 40b is located at the bottom of the sliding door 30 in the height direction f3 of the housing 10. Both the first drive mechanism 40a and the second drive mechanism 40b are connected to the sliding door 30.

[0139] By positioning the drive unit 40 at the top and / or bottom of the sliding door 30 in the height direction f3, the sliding door 30 and the first air outlet 12 can at least partially overlap in the height direction f3 of the housing 10, allowing the sliding door 30 to have a larger gap with other components in the housing 10, such as heat exchangers, in its sliding direction, and allowing the sliding door 30 to have a larger sliding space to cover the wider first air outlet 12.

[0140] This allows for the formation of a relatively large first air outlet 12 and sliding door 30 without increasing the width of the casing 10, thereby increasing the air volume of the indoor unit 100 and thus improving the cooling capacity. This enables the indoor unit 100 to quickly change the air temperature over a larger area, enhancing the user experience. At the same time, it also avoids interference between the drive device 40 and other components (such as the heat exchanger) inside the casing 10, ensuring that the sliding door 30 can smoothly open or close the first air outlet 12.

[0141] In some embodiments, such as Figure 3 and Figure 4 As shown, the indoor unit 100 includes an air guide plate 50, which is rotatably disposed at the first air outlet 12 so that the air guide plate 50 can be used to adjust the airflow direction of the first air outlet 12, that is, to adjust the air outlet direction at the first air outlet 12, thereby achieving the effect of expanding the air supply range or directional air supply.

[0142] In some embodiments, the indoor unit 100 includes a power motor 60, which is disposed in the inner cavity 11 and connected to the air guide plate 50, so that the power motor 60 can be used to drive the air guide plate 50 to rotate, thereby facilitating the rotation of the air guide plate 50 to adjust the airflow direction of the first air outlet 12.

[0143] In this application, the first air outlet 12 has an inner sidewall 121 formed in the width direction f2 of the housing 10. The inner sidewall 121 is spaced apart from the air guide plate 50 so that air can pass through the gap between the inner sidewall 121 and the air guide plate 50.

[0144] For ease of description, this application defines the minimum distance between the air guide plate 50 and the inner sidewall 121 in the width direction f2 of the housing 10 as L1. It is understood that the above definition is merely for the convenience of description and should not be used to limit the scope of protection of this application.

[0145] If L1 < w1 / 5, the minimum distance between the air guide plate 50 and the inner wall 121 is too small, which can easily cause cold air to converge and concentrate at the minimum distance between the air guide plate 50 and the inner wall 121, making the temperature of the air guide plate 50 even lower, thus making it easier to generate condensation and causing the condensation problem to become more serious.

[0146] In some embodiments, L1≥w1 / 5, ensuring that the minimum distance between the air guide plate 50 and the inner sidewall 121 can be kept within a relatively large range, reducing the concentration of cold air at the minimum distance between the air guide plate 50 and the inner sidewall 121, thereby reducing condensation.

[0147] If L1 > 3w1 / 4, the minimum distance between the air guide plate 50 and the inner wall 121 will be too large, resulting in too few air guide plates 50. This will lead to insufficient air guiding effect of the air guide plate 50, and there may still be a situation where the air is blown directly.

[0148] In some embodiments, L1≤3w1 / 4. This setting can keep the minimum distance between the air guide plate 50 and the inner sidewall 121 within a relatively large range, reducing the concentration of cold air at the minimum distance between the air guide plate 50 and the inner sidewall 121, thereby reducing condensation. It can also ensure that an appropriate number of air guide plates 50 are set at the first air outlet 12, resulting in more uniform airflow.

[0149] In some embodiments, w1 / 5 ≤ L1 ≤ 3w1 / 4, for example, w1 / 5 ≤ L1 ≤ 2w1 / 5, 2w1 / 5 ≤ L1 ≤ 3w1 / 5, or 3w1 / 5 ≤ L1 ≤ 3w1 / 4. For example, L1 = w1 / 5, 3w1 / 10, 2w1 / 5, w1 / 2, 3w1 / 5, 7w1 / 20, or 3w1 / 4, etc.

[0150] This configuration allows for a wider minimum distance between the air guide plate 50 and the inner wall 121, thus reducing the concentration of cold air between them. This, in turn, reduces condensation on the air guide plate 50, decreases the amount of condensate, and makes the airflow at the first air outlet 12 more uniform, resulting in a more even distribution of air in the room and improved cooling performance.

[0151] In some embodiments, L1 is the minimum distance in the width direction f2 between the air guide plate 50 and the inner sidewall 121 when the air guide plate 50 rotates to its limit position. The limit position is the position where the air guide plate 50 can no longer rotate along its original rotation direction.

[0152] Understandably, when the air guide plate 50 rotates to its limit position, the minimum distance between the air guide plate 50 and the inner wall 121 is the smallest, which is smaller than the minimum distance between the air guide plate 50 and the inner wall 121 when it has rotated to a certain angle but has not reached its limit position. By controlling the minimum distance between the air guide plate 50 and the inner wall 121 when it rotates to its limit position to a range greater than or equal to one-fifth of the width of the first air outlet 12, it can be ensured that no matter how many angles the air guide plate 50 rotates, the concentration of cold air at the minimum distance between the air guide plate 50 and the inner wall 121 can be reduced, thereby reducing the condensation on the air guide plate 50 and reducing the amount of condensate water.

[0153] In some embodiments, the inner sidewall 121 includes a first inner sidewall 121a and a second inner sidewall 121b that are opposite each other in the width direction f2 of the housing 10, and L1 is the minimum distance between the air guide plate 50 and the first inner sidewall 121a in the width direction f2 of the housing 10. For ease of description, this application defines the minimum distance between the air guide plate 50 and the second inner sidewall 121b in the width direction f2 of the housing 10 as L2, and defines the direction perpendicular to the height direction f3 and the thickness direction of the air guide plate 50 as the second direction f5.

[0154] It is understood that the above definitions are merely for the convenience of describing this application, but should not be used to limit the scope of protection of this application.

[0155] Understandably, during rotation, the air guide plate 50 can swing to the right or to the left. Assuming that the air guide plate 50 swings to the right, it means that one side of the air guide plate 50 in the second direction f5 moves closer to the first inner wall 121a, and the other side of the air guide plate 50 in the second direction f5 moves closer to the second inner wall 121b; then the air guide plate 50 swings to the left, it means that one side of the air guide plate 50 in the second direction f5 moves closer to the second inner wall 121b, and the other side of the air guide plate 50 in the second direction f5 moves closer to the first inner wall 121a; and vice versa.

[0156] It can be seen that during the rotation of the air guide plate 50, the minimum distance between the air guide plate 50 and the second inner side wall 121b in the width direction f2 of the housing 10 will also decrease. As a result, cold air will gather and concentrate at the minimum distance between the air guide plate 50 and the second inner side wall 121b, which will lead to condensation.

[0157] Therefore, in some embodiments, L2 ≥ w1 / 5; this setting allows the minimum distance between the air guide plate 50 and the second inner sidewall 121b to be controlled within a relatively large range, thereby increasing the minimum distance between the air guide plate 50 and the second inner sidewall 121b, which can reduce the phenomenon of cold air concentrating at the minimum distance between the air guide plate 50 and the second inner sidewall 121b, and further reduce condensation on the air guide plate 50, thus reducing the amount of condensate water.

[0158] If L2 > 3w1 / 4, the minimum distance between the air guide plate 50 and the second inner wall 121b will be too large, resulting in too few air guide plates 50. This will lead to insufficient air guiding effect of the air guide plate 50, and there may still be a situation where the air is blown directly.

[0159] In some embodiments, L2≤3w1 / 4. This setting allows the minimum distance between the air guide plate 50 and the second inner sidewall 121b to be kept within a relatively large range, reducing the concentration of cold air at the minimum distance between the air guide plate 50 and the second inner sidewall 121b, thereby reducing condensation. It also ensures that an appropriate number of air guide plates 50 are set at the first air outlet 12, resulting in more uniform airflow.

[0160] In some embodiments, w1 / 5 ≤ L2 ≤ 3w1 / 4, for example, w1 / 5 ≤ L2 ≤ 2w1 / 5, 2w1 / 5 ≤ L2 ≤ 3w1 / 5, or 3w1 / 5 ≤ L2 ≤ 3w1 / 4. For example, L2 = w1 / 5, 3w1 / 10, 2w1 / 5, w1 / 2, 3w1 / 5, 7w1 / 20, or 3w1 / 4, etc.

[0161] This configuration allows for a wider minimum distance between the air guide plate 50 and the second inner wall 121b, increasing the distance between them. This reduces the concentration of cold air between the air guide plate 50 and the second inner wall 121b, thereby reducing condensation on the air guide plate 50 and the amount of condensate. It also makes the airflow at the first air outlet 12 more uniform, allowing for a more even distribution of air in the room, resulting in a more uniform indoor temperature distribution and improved cooling performance.

[0162] In some embodiments, the number of air guide plates 50 can be one or more, and can be designed accordingly based on the actual size of the first air outlet 12. Multiple air guide plates 50 can be arranged sequentially along the height direction f3 of the housing 10, or sequentially along the width direction f2 of the housing 10.

[0163] For example, multiple air guide plates 50 are rotatably mounted at the first air outlet 12 and arranged sequentially along the width direction f2 of the housing 10. At this time, along the width direction f2 of the housing 10, the distance between the air guide plate 50 closest to the first inner sidewall 121a and the first inner sidewall 121a is L1, and the distance between the air guide plate 50 closest to the second inner sidewall 121b and the second inner sidewall 121b is L2.

[0164] In some embodiments, in order to facilitate the simultaneous rotation of multiple air guide plates 50, multiple air guide plates 50 can be connected into a whole by a connecting rod. When the power motor 60 drives one of the air guide plates 50 to rotate, all the air guide plates 50 are simultaneously driven to rotate by the connecting rod.

[0165] In this application, as Figure 5 As shown, for ease of description, the height of the housing 10 in its height direction f3 is defined as h0, and the height of the first air outlet 12 in the height direction f3 of the housing 10 is defined as h1. It is understood that the above definitions are merely for the convenience of this application's description, and should not be used to limit the scope of protection of this application.

[0166] If h1 < h0 / 2, the height of the first air outlet 12 is too small, which will affect the air volume of the first air outlet 12, thereby affecting the speed at which the indoor unit 100 changes the indoor air temperature and affecting the user's experience.

[0167] In some embodiments, h1≥h0 / 2, thereby ensuring that the first air outlet 12 also has a large size in the height direction f3 of the housing 10, so that the air volume of the indoor unit 100 can be further increased, thereby enabling the indoor unit 100 to change the air temperature over a larger range more quickly.

[0168] If h1 > 3h0 / 4, the first air outlet 12 will have a larger size in the height direction f3 of the casing 10, which will increase the overall thickness of the indoor unit 100, increase the space occupied by the indoor unit 100, and make it difficult to move the indoor unit 100.

[0169] In some embodiments, h ≤ 3h0 / 4. This configuration allows the first air outlet 12 to have a larger size in the height direction f3 of the housing 10, thereby forming a larger first air outlet 12 and ensuring the air volume of the first air outlet 12.

[0170] In some embodiments, h0 / 2 ≤ h1 ≤ 3h0 / 4, for example, h0 / 2 ≤ h1 ≤ 5h0 / 8 or 5h0 / 8 ≤ h1 ≤ 3h0 / 4. Exemplary examples include h1 = h0 / 2, 9h0 / 16, 5h0 / 8, 11h0 / 16, or 3h0 / 4, etc.

[0171] This configuration allows the indoor unit 100 to have a sufficiently large first air outlet 12, thereby increasing the air volume of the indoor unit 100 and quickly changing the air temperature over a larger area of ​​the room. It also avoids the first air outlet 12 being too high, which would increase the overall height of the indoor unit 100, thus helping to control the space occupied by the indoor unit 100 and making it easier to move the indoor unit 100.

[0172] In this application, for ease of description, the air volume of the first air outlet 12 is defined as Q. It is understood that the above definition is only for the convenience of description in this application, and should not be used to limit the scope of protection of this application.

[0173] If Q < 1600m 3 If the air volume of the indoor unit is too small (e.g., 100 m³ / h), it may lead to poor indoor air circulation, which can easily cause indoor air pollution and affect health. It may also cause uneven indoor temperature, resulting in a decrease in overall indoor comfort.

[0174] In some embodiments, Q≥1600m 3 / h, which ensures the air volume of the first air outlet 12, which can improve the circulation of indoor air, make the indoor air fresher, and help improve indoor air quality; it can also make the air flow more evenly, improve indoor comfort, and reduce the "dead corner" phenomenon, that is, the problem of poor air circulation in some corners.

[0175] If Q > 2000m 3 If the air volume of the indoor unit is too large (e.g., 100 m³ / h), it will lead to increased energy consumption and may also be accompanied by increased noise.

[0176] In some embodiments, Q≤2000m 3 / h. This setting allows the first air outlet 12 to have a relatively large air volume while reducing energy consumption and noise.

[0177] In some embodiments, 1600m 3 / h≤Q≤2000m 3 / h, for example, 1600m 3 / h≤Q≤1700m 3 / h, 1700m 3 / h≤Q≤1800m 3 / h, 1800m 3 / h≤Q≤1900m 3 / h or 1900m 3 / h≤Q≤2000m 3 / h. For example, Q = 1600m 3 / h, 1650m 3 / h, 1700m 3 / h, 1750m 3 / h, 1800m 3 / h, 1850m 3 / h, 1900m 3 / h、1950m 3 / h or 2000m 3 / h etc.

[0178] This configuration allows the first air outlet 12 to have sufficient airflow to accelerate the removal of hot indoor air, thereby improving indoor air circulation, accelerating cooling speed, and enhancing the cooling effect; it also reduces energy consumption and noise.

[0179] In this application, for ease of description, the air supply angle of the first air outlet 12 is defined as α. It is understood that the above definition is only for the convenience of description in this application, and should not be used to limit the scope of protection of this application.

[0180] If α < 90°, it may result in limited airflow range, which in turn leads to poor uniformity of indoor temperature.

[0181] In some embodiments, α ≥ 90°, ensuring that the indoor unit 100 has a wide air supply range, enhancing indoor air circulation, and improving cooling effect.

[0182] If α > 150°, it may cause cold air to blow directly and concentrated on one side of the room, while other areas are not adequately covered by the cold air, resulting in uneven indoor temperature. For example, the area near the first air outlet 12 may be too cold, while the area far from the first air outlet 12 may not feel cool enough.

[0183] In some embodiments, α ≤ 150°. This setting allows the indoor unit 100 to have a wide air outlet range while preventing cold air from blowing directly onto a specific area of ​​the room, thus ensuring the cooling effect.

[0184] In some embodiments, 90°≤α≤150°, for example, 90°≤α≤100°, 100°≤α≤110°, 110°≤α≤120°, 120°≤α≤130°, 130°≤α≤140°, or 140°≤α≤150°. For example, α = 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, or 150°, etc.

[0185] This configuration allows for a wider area of ​​air blown from the first air outlet 12, which helps to cover all parts of the room, resulting in a more uniform indoor temperature distribution and improved cooling performance.

[0186] In this application, the air delivery distance of the first air outlet 12 is defined as the farthest distance that the air blown from the first air outlet 12 can reach at a wind speed of 0.3 m / s, starting from the first air outlet 12. For ease of description, the air delivery distance of the first air outlet 12 is defined as e. It is understood that the above definition is merely for the convenience of this application's description and should not be used to limit the scope of protection of this application.

[0187] If e < 15m, the air supply distance is short, which may lead to excessive local wind force, causing some areas to feel strong winds while other areas do not feel the cooling effect, resulting in poor uniformity of indoor temperature.

[0188] In some embodiments, e≥15m, which allows the indoor unit 100 to have a longer air blowing distance, thereby improving the heat exchange efficiency of the indoor unit 100.

[0189] If e > 25m, it may lead to increased energy consumption, and may also be accompanied by increased noise.

[0190] In some embodiments, e ≤ 25m. This allows the indoor unit 100 to have a longer airflow distance, which is beneficial for improving indoor air circulation and changing indoor temperature.

[0191] In some embodiments, 15m ≤ e ≤ 25m, for example, 15m ≤ e ≤ 16m, 16m ≤ e ≤ 17m, 17m ≤ e ≤ 18m, 18m ≤ e ≤ 19m, 19m ≤ e ≤ 20m, 20m ≤ e ≤ 21m, 21m ≤ e ≤ 22m, 22m ≤ e ≤ 23m, 23m ≤ e ≤ 24m, or 24m ≤ e ≤ 25m. For example, e = 15m, 15.5m, 16m, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm, 19.5mm, 20mm, 20.5mm, 21mm, 21.5mm, 22mm, 22.5mm, 23mm, 23.5mm, 24mm, 24.5mm, or 25mm, etc.

[0192] This configuration allows the indoor unit 100 to have sufficient airflow distance, which facilitates the spread of air to all parts of the room, thereby achieving a more uniform indoor temperature distribution and improving the cooling effect; it also reduces energy consumption and noise.

[0193] Since the width of the first air outlet 12 in the width direction f2 of the housing 10 has increased in this application, the width of the sliding door 30 in the width direction f2 of the housing 10 will also increase accordingly, and thus the weight of the sliding door 30 will also increase accordingly.

[0194] Therefore, such as Figure 5 and Figure 6 As shown, the preferred drive device 40 of this application includes a first drive mechanism 40a and a second drive mechanism 40b. The first drive mechanism 40a is located at the top of the sliding door 30, and the second drive mechanism 40b is located at the bottom of the sliding door 30. Both the first drive mechanism 40a and the second drive mechanism 40b are connected to the sliding door 30.

[0195] This configuration increases the overall driving force of the drive device 40, making it easier for the drive device 40 to drive the sliding door 30 to slide. At the same time, since the two ends of the sliding door 30 in the height direction f3 of the housing 10 are respectively connected by the first drive mechanism 40a and the second drive mechanism 40b, compared to the sliding door 30 being connected to the drive device 40 at only one end, the connection area between the sliding door 30 and the drive device 40 can be increased, thereby improving the sliding stability of the sliding door 30 when sliding.

[0196] In some embodiments, combined with Figure 5 , Figure 6 and Figure 7 As shown, the drive device 40 includes a mounting box 41, a drive motor 42, a drive gear 43, and a rack structure 44. Specifically, both the first drive mechanism 40a and the second drive mechanism 40b include a mounting box 41, a drive motor 42, a drive gear 43, and a rack structure 44.

[0197] The mounting box 41 is located in the inner cavity of the housing 10. The drive motor 42 and the power motor 60 are both mounted in the mounting box 41. The drive gear 43 is connected to the output shaft of the drive motor 42. The rack structure 44 is slidably mounted in the mounting box 41 and meshes with the drive gear 43. The rack structure 44 is connected to the sliding door 30.

[0198] When the drive motor 42 starts running, the output shaft of the drive motor 42 drives the drive gear 43 to rotate. Under the rotation of the drive gear 43, the gear structure slides relative to the mounting box 41 and simultaneously drives the sliding door 30 to slide, so as to open or close the first air outlet 12.

[0199] Because the transmission between gears and racks is relatively smooth, the first drive mechanism 40a and the second drive mechanism 40b use the meshing of drive gear 43 and rack structure 44 to convert the rotational motion of drive motor 42 into the sliding motion of sliding door 30, which can reduce vibration and noise and improve the operational stability of the system. At the same time, because the transmission between gears and racks is reliable and has a long service life, the service life of the first drive mechanism 40a and the second drive mechanism 40b can be improved.

[0200] Furthermore, since both the drive motor 42 and the power motor 60 are mounted in the mounting box 41, integrating both motors into the mounting box 41 saves installation space.

[0201] If the drive gear 43 and the rack structure 44 are arranged vertically along the height direction f3 of the housing 10, for example, the rack structure 44 is located below the drive gear 43 in the height direction f3 of the housing 10, the rack structure 44 and the drive gear 43 are meshed vertically. However, since the rack structure 44 is connected to the sliding door 30, especially under the design premise of the large first air outlet 12 in this application, the overall weight of the sliding door 30 is relatively heavy, which makes the rack structure 44 subject to greater gravity from the sliding door 30. This makes it easier for the rack structure 44 to deform downward, thereby causing the rack structure 44 and the drive gear 43 to disengage vertically, affecting their meshing, and thus affecting the sliding of the rack structure 44 and the sliding door 30.

[0202] Therefore, in some embodiments, the axial direction of the drive gear 43 extends along the height direction f3 of the housing 10, that is, the axial direction of the drive gear 43 is parallel to the height direction f3 of the housing 10, and the drive gear 43 and the rack structure 44 are arranged along the length direction f1 of the housing 10, and the drive gear 43 and the rack structure 44 are meshed in the length direction f1 of the housing 10.

[0203] Specifically, the drive gear 43 is provided with a plurality of gear teeth 431 arranged around its axial direction. All gear teeth 431 extend along the axial direction of the drive gear 43, that is, they extend along the height direction f3 of the housing 10. The rack structure 44 has a plurality of rack teeth 44a on its surface along the length direction f1 of the housing 10. These rack teeth 44a are arranged along the sliding direction of the sliding door 30, and each rack tooth 44a extends along the height direction f3 of the housing 10. The rack teeth 44a mesh with the gear teeth 431.

[0204] This arrangement ensures that the arrangement direction of the drive gear 43 and the rack structure 44 is no longer in the same direction as the gravity direction of the sliding door 30. Therefore, even if the rack structure 44 is deformed downward along the height direction f3 of the housing 10 by the weight of the sliding door 30, the drive gear 43 and the rack structure 44 can still maintain meshing to ensure that the drive gear 43 can smoothly drive the rack structure 44 to slide, thereby ensuring that the sliding door 30 can slide smoothly and improving the stability of the sliding door 30.

[0205] In some embodiments, combined with Figure 6 , Figure 8 and Figure 9 As shown, one of the mounting box 41 and the rack structure 44 has a guide groove structure 41a, and the other of the mounting box 41 and the rack structure 44 has a guide post structure 443, which is slidably embedded in the guide groove structure 41a. Thus, the cooperation of the guide groove structure 41a and the guide post structure 443 provides guidance for the sliding of the rack structure 44, improving the sliding stability of the rack structure 44, thereby improving the sliding stability of the sliding door 30, allowing the sliding door 30 to slide more smoothly, and reducing abnormal situations such as jamming during operation.

[0206] For example, a guide groove structure 41a is formed on the surface of the mounting box 41 facing the rack structure 44, and a guide post structure 443 is provided on the surface of the rack structure 44 facing the mounting box 41. The guide post structure 443 is slidably embedded in the guide groove structure 41a to provide guidance for the sliding of the rack structure 44.

[0207] In some embodiments, the mounting box 41 and the rack structure 44 can be made of materials such as plastic, silicone, or rubber, so that the mounting box 41 and the rack structure 44 can be formed by injection molding, which simplifies the processing of the mounting box 41 and the rack structure 44 and improves processing efficiency.

[0208] In some embodiments, the guide groove structure 41a includes a first groove 41a1 and a second groove 41a2 that are interconnected along its depth direction. During assembly, the guide post structure 443 is inserted into the first groove 41a1 from the second groove 41a2. The first groove 41a1 includes a bottom surface 41a11 and a first sidewall surface 41a12 connected to the bottom surface 41a11. The second groove 41a2 includes a second sidewall surface 41a21 connected to the first sidewall surface 41a12.

[0209] In some embodiments, the first groove 41a1 includes a groove bottom surface 41a11 and a first groove side wall surface 41a12 connected to the groove bottom surface 41a11. The first groove side wall surface 41a12 is perpendicular to the groove bottom surface 41a11, and the groove opening width of the first groove 41a1 is smaller than the groove opening width of the second groove 41a2.

[0210] With this configuration, when the rack structure 44 moves along the height direction f3 of the housing, since the first groove sidewall 41a12 is perpendicular to the groove bottom surface 41a11, the fit clearance between the outer peripheral surface of the guide post structure 443 and the first groove sidewall 41a12 can always remain consistent and unchanged. This ensures that the fit clearance between the guide post structure 443 and the guide groove structure 41a remains consistent, making the fit between the guide post structure 443 and the guide groove structure 41a more stable and less prone to shaking. This, in turn, provides a more stable guiding effect for the sliding of the rack structure 44, further improving the sliding stability of the sliding door 30, making the sliding door 30 slide more smoothly, and reducing abnormal situations such as jamming during operation.

[0211] Meanwhile, since the groove width of the first groove 41a1 is smaller than the groove width of the second groove 41a2, the second groove side wall 41a21 of the second groove 41a2 has a draft angle, which facilitates smooth demolding when the mounting box 41 is formed by injection molding, thus ensuring that the processing technology of the mounting box 41 is relatively simple.

[0212] In some embodiments, the first groove sidewall 41a12 is perpendicular to the groove bottom surface 41a11, and in the opening direction of the guide groove structure 41a, the second groove sidewall 41a21 gradually widens from the first groove sidewall 41a11, so that the second groove body is formed into a widened groove.

[0213] With this configuration, when the rack structure 44 moves along the height direction f3 of the housing 10, since the first groove sidewall 41a12 is perpendicular to the groove bottom surface 41a11, the fit clearance between the outer peripheral surface of the guide post structure 443 and the first groove sidewall 41a12 can always remain consistent and unchanged. This ensures that the fit clearance between the guide post structure 443 and the guide groove structure 41a remains consistent, making the fit between the guide post structure 443 and the guide groove structure 41a more stable and less prone to shaking. This, in turn, provides a more stable guiding effect for the sliding of the rack structure 44, further improving the sliding stability of the sliding door 30, making the sliding door 30 slide more smoothly, and reducing abnormal situations such as jamming during operation.

[0214] Meanwhile, since the second side wall of the second groove body 41a2 gradually widens from the first groove wall in the opening direction of the guide groove structure, the second groove body is formed into a widened groove, and the second side wall of the second groove body 41a2 has a draft angle. When the mounting box 41 is formed by injection molding, it is easy to demold smoothly, thus ensuring that the processing technology of the mounting box 41 is relatively simple.

[0215] In some embodiments, in the opening direction of the guide groove structure 41a, the second groove sidewall 41a21 of the second groove body 41a2 can gradually tilt from the first groove sidewall 41a12 toward the direction away from the center of the second groove body 41a2 to form an inclined surface, so that the second groove sidewall 41a21 of the second groove body 41a2 has a draft angle, which facilitates smooth demolding when the mounting box 41 is formed by injection molding, thereby ensuring that the processing technology of the mounting box 41 is relatively simple.

[0216] In other embodiments, in the opening direction of the guide groove structure 41a, the second groove side wall 41a21 of the second groove body 41a2 can gradually tilt from the first groove side wall 41a12 toward the direction away from the center of the second groove body 41a2 to form a guide arc surface, so that the second groove side wall 41a21 of the second groove body 41a2 has a draft angle, which facilitates smooth demolding when the mounting box 41 is formed by injection molding, thereby ensuring that the processing technology of the mounting box 41 is relatively simple.

[0217] In some embodiments, each mounting box 41 includes a first mounting base 411 and a second mounting base 412 connected to each other. A drive motor 42 is mounted on the first mounting base 411, a drive gear 43 is rotatably disposed on the second mounting base 412 and located between the first mounting base 411 and the second mounting base 412, and a rack structure 44 is slidably connected between the first mounting base 411 and the second mounting base 412.

[0218] With this configuration, the rack structure 44 is located in the middle of the first mounting base 411 and the second mounting base 412. The rack structure 44 can be limited in the height direction f3 of the housing by the first mounting base 411 and the second mounting base 412, which helps to improve the sliding stability of the rack structure 44.

[0219] In some embodiments, such as Figure 9 As shown, the guide groove structure 41a includes a first guide groove 411a formed on the first mounting base 411 and a second guide groove 412a formed on the second mounting base 412. Both the first guide groove 411a and the second guide groove 412a include a first groove body 41a1 and a second groove body 41a2. The guide post structure 443 includes a first guide post 443a formed on one side of the rack structure 44 and a second guide post 443b formed on the other side of the rack structure 44. The first guide post 443a is slidably embedded in the first guide groove 411a, and the second guide post 443b is slidably embedded in the second guide groove 412a.

[0220] This configuration allows for the placement of a first guide post 443a at the upper part of the rack structure 44 along the height direction f3 of the housing, to engage with the first guide groove 411a of the first mounting base 411. Additionally, a second guide post 443b can be placed at the lower part of the rack structure 44 along the height direction f3 of the housing 10, to engage with the first guide groove 411a of the first mounting base 411. Through the engagement of the first guide post 443a and the first guide groove 411a, and the engagement of the second guide post 443b and the second guide groove 412a, a dual guiding effect can be achieved on the sliding stroke of the rack structure 44, thereby further improving the sliding stability of the rack structure 44.

[0221] In some embodiments, the first guide post 443a can be set as a cylinder, which can reduce the friction between the first guide post 443a and the first guide groove 411a, which is beneficial to reduce the sliding resistance of the rack structure 44, thereby facilitating the smooth sliding of the sliding door 30. Furthermore, because the contact surface is smooth, the first guide post 443a is less likely to scratch the first guide groove 411a.

[0222] Similarly, in some embodiments, the second guide post 443b can be set as a cylinder, which can reduce the friction between the second guide post 443b and the second guide groove 412a, which is beneficial to reduce the sliding resistance of the rack structure 44, thereby facilitating the smooth sliding of the sliding door 30. Furthermore, because the contact surface is smooth, the second guide post 443b is less likely to scratch the second guide groove 412a.

[0223] In this application, both the first guide groove 411a and the second guide groove 412a include a first groove wall 411a1 and a second groove wall 411a2 extending along the sliding direction of the sliding door 30. Each of the first groove wall 411a1 and the second groove wall 411a2 includes a first groove sidewall surface 41a11 and a second groove sidewall surface 41a21. For ease of description, the arrangement direction of the first groove wall 411a1 and the second groove wall 411a2 is configured as a first direction f4. It is understood that the above definitions are merely for the convenience of describing this application and should not be used to limit the scope of protection of this application.

[0224] In some embodiments, the first guide post 443a and the second guide post 443b have different dimensions in the first direction f4, and the first guide groove 411a and the second guide groove 412a have different dimensions in the first direction f4.

[0225] Understandably, the first guide post 443a and the first guide groove 411a are approximately equal in size in the first direction f4 so that the first guide post 443a can be inserted into the first guide groove 411a, and the second guide post 443b and the second guide groove 412a are approximately equal in size in the first direction f4 so that the second guide post 443b can be inserted into the second guide groove 412a.

[0226] When the dimensions of the first guide post 443a and the second guide post 443b are different in the first direction f4, and the dimensions of the first guide groove 411a and the second guide groove 412a are different in the first direction f4, the dimensions of the first guide post 443a and the second guide groove 412a are different in the first direction f4, and the dimensions of the second guide post 443b and the first guide groove 411a are different in the first direction f4.

[0227] For example, in the first direction f4, if the size of the first guide post 443a is larger than the size of the second guide post 443b, then in the first direction f4, the size of the first guide post 443a is larger than the size of the second guide groove 412a, and the size of the second guide post 443b is smaller than the size of the first guide groove 411a. If the rack structure 44 is installed upside down in the height direction f3 of the housing 10, although the second guide post 443b can be inserted into the first guide groove 411a, it cannot be inserted into the second guide groove 412a, thus reminding the installer that the gear structure is installed upside down.

[0228] That is, during the assembly process, the rack structure 44 can only be successfully assembled between the first mounting base 411 and the second mounting base 412 when the first guide post 443a is fitted into the first guide groove 411a and the second guide post 443b is fitted into the second guide groove 412a. This prevents the rack structure 44 from being installed backwards and achieves a foolproof installation effect.

[0229] In some embodiments, combined with Figures 10 to 12 As shown, the first drive mechanism 40a of the drive device is provided with a first connecting part 441. Specifically, the rack structure 44 of the first drive mechanism 40a is provided with the first connecting part 441, so as to provide a position for connection with the sliding door 30.

[0230] In some embodiments, the sliding door 30 includes a door body 31 and a first end plate 32. The first end plate 32 is connected to one end of the door body 31 in the height direction f3 of the housing, and the first end plate 32 is set at an angle to the door body 31, for example, the first end plate 32 and the door body 31 are set at approximately 90°. Of course, in other embodiments, the first end plate 32 and the door body 31 can also be set at other angles, such as 60°, 70°, 75°, 80°, 85°, etc.

[0231] In some embodiments, the first end plate 32 may abut against the top of the first connecting portion 441 in the height direction f3 of the housing, thereby enabling the first connecting portion 441 to support the sliding door 30.

[0232] In some embodiments, such as Figure 13 and Figure 14As shown, the indoor unit also includes threaded fasteners (not shown). The first connecting part 441 is provided with a first connecting hole 4411. The axial direction of the first connecting hole 4411 extends along the height direction f3 of the housing. For example, the axial direction of the first connecting hole 4411 is parallel to the height direction f3 of the housing. The first end plate 32 is provided with a second connecting hole 321 that extends along the height direction f3 of the housing. The second connecting hole 321 is aligned with the first connecting hole 4411 so that the threaded fastener can pass through the second connecting hole 321 and the first connecting hole 4411, thereby enabling the first connecting hole 4411 and the second connecting hole 321 to be connected by the threaded fastener.

[0233] This configuration simplifies the connection between the sliding door 30 and the rack structure 44 of the first drive mechanism 40a. Furthermore, since the sliding door 30 abuts against the top of the first connecting part 441 via the first end plate 32, and the first connecting part 441 supports the sliding door 30, it can share some of the weight of the sliding door 30, preventing the entire weight of the sliding door 30 from being applied to the threaded fasteners. This ensures the reliability of the connection between the sliding door 30 and the rack structure 44 of the first drive mechanism 40a while reducing the number of threaded fasteners, thereby greatly improving the assembly efficiency between the sliding door 30 and the rack structure 44.

[0234] Furthermore, especially based on the design of the large first air outlet in this application, that is, based on the design of increasing the width of the first air outlet in the width direction of the housing, as the width of the first air outlet in the width direction of the housing increases, the width of the sliding door 30 in the width direction of the housing will also increase, and the weight of the sliding door 30 will also increase. By using the first end plate 32 to abut against the top of the first connecting part 441, part of the weight of the sliding door 30 can be distributed, avoiding the entire weight of the sliding door 30 being applied to the threaded fastener. This is beneficial to improving the service life of the threaded fastener and reducing the risk of the sliding door 30 detaching from the rack structure 44 and falling.

[0235] Alternatively, the threaded fastener may be a screw or bolt, etc.

[0236] Understandably, when the threaded fastener is a screw, the first connecting hole 4411 is a threaded hole, while the second connecting hole 321 can be either a threaded hole or a smooth hole. When the threaded fastener is a bolt, both the first connecting hole 4411 and the second connecting hole 321 can be threaded holes or both can be smooth holes. In this case, the threaded fastener passes through the second connecting hole 321 and the first connecting hole 4411, and then a nut is used to thread it onto the fastener, thereby achieving the connection and fixation of the first connecting hole 4411 and the second connecting hole 321.

[0237] In some embodiments, such as Figure 13 and Figure 14As shown, one of the first end plate 32 and the first connecting part 441 is provided with a first positioning through hole 322, and the other of the first end plate 32 and the first connecting part 441 is provided with a first positioning post 4412. That is, when the first end plate 32 is provided with the first positioning through hole 322, the first connecting part 441 is provided with the first positioning post 4412, and when the first end plate 32 is provided with the first positioning post 4412, the first connecting part 441 is provided with the first positioning through hole 322.

[0238] The following describes the specific structure of the first positioning through hole 322 and the first positioning post 4412, as well as their positions and connection relationships, taking the first end plate 32 having a first positioning through hole 322 and the first connecting part 441 having a first positioning post 4412 as an example.

[0239] In this application, the first positioning through hole 322 extends through the first end plate 32 along the height direction f3 of the housing, and the first positioning post 4412 extends along the height direction f3 of the housing and is inserted into the first positioning through hole 322.

[0240] Therefore, during assembly, the first positioning through hole 322 on the sliding door 30 is fitted onto the outer periphery of the first positioning post 4412 on the rack structure 44 of the first drive mechanism from top to bottom. This enables precise positioning between the second connecting hole 321 and the first connecting hole 4411, aligning the second connecting hole 321 with the first connecting hole 4411. This allows threaded fasteners to be quickly inserted into the second connecting hole 321 and the first connecting hole 4411, improving the installation efficiency between the sliding door 30 and the first drive mechanism 40a.

[0241] In some embodiments, combined with Figures 13 to 15 As shown, the second drive mechanism 40b is provided with a second connecting part 442. Specifically, the rack structure 44 of the second drive mechanism 40b is provided with a second connecting part 442. The second connecting part 442 and the first connecting part 441 are correspondingly provided in the height direction f3 of the housing 10, so as to provide a position for connection with the sliding door 30 by using the second connecting part 442.

[0242] In some embodiments, the sliding door 30 further includes a second end plate 33, which is connected to the other end of the door body 31 in the height direction f3 of the housing 10, and the second end plate 33 is set at an angle to the door body 31, for example, the second end plate 33 and the door body 31 are set at approximately 90°. Of course, in other embodiments, the second end plate 33 and the door body 31 can also be set at other angles, such as 60°, 70°, 75°, 80°, 85°, etc.

[0243] In some embodiments, one of the second end plate 33 and the second connecting portion 442 is provided with a second positioning post 4421, and the other of the second end plate 33 and the second connecting portion 442 is provided with a second positioning through hole 331. That is, when the second end plate 33 is provided with a second positioning through hole 331, the second connecting portion 442 is provided with a second positioning post 4421, and when the second end plate 33 is provided with a second positioning post 4421, the second connecting portion 442 is provided with a second positioning through hole 331.

[0244] The following description uses the example of the second end plate 33 having a second positioning through hole 331 and the second connecting part 442 having a second positioning post 4421 to illustrate the specific structure of the second positioning through hole 331 and the second positioning post 4421, as well as their positions and connection relationship.

[0245] In this application, the second positioning through hole 331 extends through the second end plate 33 along the height direction f3 of the housing, and the second positioning post 4421 extends along the height direction f3 of the housing and is inserted into the second positioning through hole 331.

[0246] Therefore, during assembly, the second positioning through hole 331 on the sliding door 30 is fitted onto the outer periphery of the second positioning post 4421 on the rack structure 44 of the second drive mechanism from top to bottom, so as to realize the connection between the sliding door 30 and the second drive mechanism 40b in the length and width directions of the housing. In the height direction f3 of the housing, the sliding door 30 is locked by threaded fasteners, so the second positioning through hole 331 can be kept in the state of being fitted onto the outer periphery of the second positioning post 4421, ensuring that the rack structure 44 of the second drive mechanism 40b can drive the sliding door 30 to slide together during the sliding process.

[0247] Since the sliding door 30 is driven to slide by the first drive mechanism 40a and the second drive mechanism 40b, sometimes, inevitably, the drive motors of the first drive mechanism 40a and the second drive mechanism 40b will start asynchronously. This will cause the first drive mechanism 40a and the second drive mechanism 40b to pull against each other at both ends of the sliding door 30. This will not only affect the sliding of the sliding door 30, causing jamming and noise, but may even damage the sliding door 30.

[0248] Therefore, in combination Figure 15 and Figure 16 As shown, in some embodiments, the second end plate 33 is located above the second connecting portion 442 in the height direction f3 of the housing, and the second end plate 33 is spaced apart from the second connecting portion 442 in the height direction f3 of the housing, that is, a gap is formed between the surfaces of the second end plate 33 and the second connecting portion 442 facing each other.

[0249] Thus, when the drive motors of the first drive mechanism 40a and the second drive mechanism 40b start asynchronously, the distance between the surfaces of the second end plate 33 and the second connecting part 442 facing each other, combined with the non-fixed design of the second end plate 33 and the second connecting part 442 in the height direction f3 of the housing, allows the drive motor that starts first to drive one end of the sliding door 30 to slide first, avoiding the first drive mechanism 40a and the second drive mechanism 40b forming a pull at both ends of the sliding door 30, ensuring that the sliding door 30 can slide smoothly, avoiding jamming and noise, and also avoiding damage to the sliding door 30, thus improving the service life of the sliding door 30.

[0250] Meanwhile, the distance between the second end plate 33 and the second connecting part 442 in the height direction f3 of the housing 10 can also provide machining error space for the height of the sliding door 30 in the height direction f3 of the housing, so as to avoid interference between the sliding door 30 and the second motion mechanism and affect the installation of the sliding door 30.

[0251] In some embodiments, combined with Figure 15 and Figure 16 As shown, the second connecting part 442 is provided with a third connecting hole 4422. The axial direction of the third connecting hole 4422 extends along the height direction f3 of the housing 10, and the third connecting hole 4422 is disposed opposite to the first connecting hole 4411 in the height direction f3 of the housing.

[0252] With this configuration, even if the rack structure 44 of the second drive mechanism 40b is assembled into the mounting box 41 of the first drive mechanism 40a, the third connecting hole 4422 can be used as the first connecting hole 4411 for threaded fasteners to pass through, thereby achieving the connection and fixation between the rack structure 44 of the second drive mechanism 40b and the sliding door 30. This makes the rack structure 44 of the first drive mechanism 40a and the second drive mechanism 40b interchangeable without distinction, providing strong versatility and improving the assembly flexibility of the first drive mechanism 40a, the second drive mechanism 40b, and the sliding door 30.

[0253] Understandably, since the third connecting hole 4422 can be used as the first connecting hole 4411, the third connecting hole 4422 and the first connecting hole 4411 are of the same type. That is, when the first connecting hole 4411 is a threaded hole, the third connecting hole 4422 is also a threaded hole. When the first connecting hole 4411 is a smooth hole, the third connecting hole 4422 is also a smooth hole.

[0254] In some embodiments, the second end plate 33 is provided with a fourth connecting hole 332 that extends along the height direction f3 of the housing, and the fourth connecting hole 332 is disposed opposite to the second connecting hole 321 in the height direction f3 of the housing 10.

[0255] With this configuration, even if the sliding door 30 is turned upside down, that is, the second end plate 33 of the sliding door 30 is pressed against the top of the first connecting part 441, the fourth connecting hole 332 can be used as the second connecting hole 321 for threaded fasteners to pass through, and the sliding door 30 is connected and fixed to the first connecting part 441. This allows the sliding door 30 to be used in both directions without needing to distinguish the orientation, which is highly versatile and helps to improve the assembly flexibility of the first drive mechanism 40a, the second drive mechanism 40b and the sliding door 30.

[0256] Understandably, since the fourth connecting hole 332 can be used as the second connecting hole 321, the fourth connecting hole 332 and the second connecting hole 321 are of the same type. That is, when the second connecting hole 321 is a threaded hole, the fourth connecting hole 332 is also a threaded hole. When the second connecting hole 321 is a smooth hole, the fourth connecting hole 332 is also a smooth hole.

[0257] The researchers of this application discovered that vertical air conditioners occasionally produce abnormal noises during operation. After repeated investigations, they found that the noises are mainly caused by friction between the first mounting bracket 411 and the second mounting bracket 412. Specifically, during cooling or heating, the temperature at the first air outlet 12 fluctuates significantly, especially given the large first air outlet 12 design used in this application. Since the first mounting bracket 411 and the second mounting bracket 412 are very close to the first air outlet 12, they are prone to thermal expansion and contraction, leading to friction between them and producing abnormal noises, such as a "clicking" sound.

[0258] Therefore, in some embodiments, such as Figures 16 to 19 As shown, the first mounting base 411 and / or the second mounting base 412 are provided with a support structure 41b. The support structure 41b is located between the first mounting base 411 and the second mounting base 412, and the support structure 41b is used to create a gap between the first mounting base 411 and the second mounting base 412. Therefore, when the first mounting base 411 and the second mounting base 412 undergo thermal expansion and contraction, the gap between the first mounting base 411 and the second mounting base 412 can provide expansion space for the expansion of the first mounting base 411 and the second mounting base 412, reducing abnormal noise caused by friction from the thermal expansion and contraction of the first mounting base 411 and the second mounting base 412.

[0259] As an example, when the first mounting base 411 is provided with a support structure 41b, the support structure 41b abuts against the second mounting base 412, so that a gap is formed between the first mounting base 411 and the second mounting base 412, providing expansion space for the expansion of the first mounting base 411 and the second mounting base 412.

[0260] Optionally, multiple support structures 41b can be provided, such as two, three, four, five, six, etc., which helps to improve the support stability between the first mounting base 411 and the second mounting base 412, making the overall structure of the mounting box 41 more stable. Multiple support structures 41b can be arranged on the first mounting base 411 along the sliding direction of the sliding door 30, with a regular arrangement and stable structure.

[0261] In another exemplary embodiment, the second mounting base 412 is provided with a support structure 41b that abuts against the first mounting base 411, thereby creating a gap between the first mounting base 411 and the second mounting base 412 to provide expansion space for the expansion of the first mounting base 411 and the second mounting base 412.

[0262] Optionally, multiple support structures 41b can be provided, such as two, three, four, five, six, etc., which helps to improve the support stability between the first mounting base 411 and the second mounting base 412, making the overall structure of the mounting box 41 more stable. Multiple support structures 41b can be arranged on the second mounting base 412 along the sliding direction of the sliding door 30, with a regular arrangement and stable structure.

[0263] In another exemplary embodiment, the support structure 41b includes a first support portion 411b formed on the first mounting base 411 and a second support portion 412b formed on the second mounting base 412. The first support portion 411b and the second support portion 412b are both located between the first mounting base 411 and the second mounting base 412, and the first support portion 411b and the second support portion 412b abut against each other so that a gap is formed between the first mounting base 411 and the second mounting base 412, providing expansion space for the expansion of the first mounting base 411 and the second mounting base 412.

[0264] In this application, for ease of description, the distance between the first mounting base 411 and the second mounting base 412 in the direction from the first mounting base 411 to the second mounting base 412, for example, in the housing height direction f3, is defined as 'a'. It is understood that the above definition is merely for the convenience of description and should not be used to limit the scope of protection of this application.

[0265] If a < 1.0 mm, the gap between the first mounting base 411 and the second mounting base 412 is too small. When the expansion of the first mounting base 411 and the second mounting base 412 is relatively large, the first mounting base 411 and the second mounting base 412 may still come into contact and rub against each other, resulting in abnormal noise.

[0266] In some embodiments, a ≥ 1.0 mm ensures that there is a certain gap between the first mounting base 411 and the second mounting base 412, so as to avoid contact and friction between the first mounting base 411 and the second mounting base 412 when large expansion occurs.

[0267] If a > 5.0 mm, there will be a large gap between the first mounting base 411 and the second mounting base 412, thereby increasing the overall thickness of the mounting box 41, increasing the space occupied by the indoor unit, and making it difficult to move the indoor unit.

[0268] In some embodiments, a ≤ 5.0 mm. This setting allows for a certain distance between the first mounting base 411 and the second mounting base 412, providing sufficient expansion space for the expansion of the first mounting base 411 and the second mounting base 412. It also makes the structure of the mounting box 41 more compact, which helps to reduce the space occupied by the mounting box 41 on the housing 10.

[0269] In some embodiments, 1.0mm ≤ a ≤ 5.0mm, for example, 1.0mm ≤ a ≤ 2.0mm, 2.0mm ≤ a ≤ 3.0mm, 3.0mm ≤ a ≤ 4.0mm, or 4.0mm ≤ a ≤ 5.0mm. For example, a = 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm, or 5.0mm, etc.

[0270] This arrangement ensures sufficient spacing between the first mounting base 411 and the second mounting base 412, providing ample expansion space for their expansion, reducing abnormal noise, and preventing excessive spacing between the first mounting base 411 and the second mounting base 412 from increasing the overall thickness of the mounting box 41, thus avoiding the situation where the indoor unit occupies too much space and is not conducive to its transportation.

[0271] In some embodiments, such as Figures 18 to 20 As shown, one of the first support portion 411b and the second support portion 412b may be provided with a receiving groove 411b1, and one end of the other support portion 411b and the second support portion 412b is embedded in the receiving groove 411b1. That is, when the first support portion 411b is provided with the receiving groove 411b1, one end of the second support portion 412b is embedded in the receiving groove 411b1; and when the second support portion 412b is provided with the receiving groove 411b1, one end of the first support portion 411b is embedded in the receiving groove 411b1.

[0272] With this configuration, the first mounting base 411 and the second mounting base 412 are initially positioned for connection by the cooperation of one end of the first support part 411b or the second support part 412b with the receiving groove 411b1, thereby improving the assembly efficiency of the first mounting base 411 and the second mounting base 412; at the same time, the positioning function can be achieved without the need for additional positioning pins to cooperate with the receiving groove.

[0273] In some embodiments, the support structure 41b may include a plurality of first support portions 411b and a plurality of second support portions 412b, with one first support portion 411b and one second support portion 412b abutting each other, which helps to improve the support stability between the first mounting base 411 and the second mounting base 412, making the overall structure of the mounting box 41 more stable.

[0274] For example, multiple first support parts 411b can be arranged on the second mounting base 412 along the sliding direction of the sliding door 30, and multiple second support parts 412b can be arranged on the second mounting base 412 along the sliding direction of the sliding door 30, with regular arrangement and stable structure.

[0275] In some embodiments, the outer peripheral side of the support structure 41b is provided with reinforcing ribs 41b1 to improve the structural strength of the support structure 41b. Multiple reinforcing ribs 41b1 may be provided, and these ribs 41b1 may be arranged at intervals along the circumference of the support structure 41b, thereby further improving the structural strength of the support structure 41b.

[0276] For example, the outer peripheral surfaces of the first support portion 411b and the second support portion 412b are provided with reinforcing ribs 41b1 to improve the structural strength of the first support portion 411b and the second support portion 412b.

[0277] In some embodiments, the indoor unit further includes a threaded locking element (not shown), and the first mounting base 411 and the second mounting base 412 can be fixedly connected by the threaded locking element, providing a stable and reliable connection. The threaded locking element can be a screw or a bolt.

[0278] Understandably, when only the first mounting base 411 has a support structure 41b, the support structure 41b is connected to the second mounting base 412 via a threaded locking member; when only the second mounting base 412 has a support structure 41b, the support structure 41b is connected to the first mounting base 411 via a threaded locking member; and when the support structure 41b includes a first support portion 411b formed on the first mounting base 411 and a second support portion 412b formed on the second mounting base 412, the first support portion 411b and the second support portion 412b are connected via a threaded locking member.

[0279] In this application, for ease of description, the diameter of the threaded locking element is defined as d. It is understood that the above definition is only for the convenience of description in this application, and should not be used to limit the scope of protection of this application.

[0280] Understandably, the first mounting base 411 and the second mounting base 412 in this application are mainly connected by threaded locking components. If d < 3.5 mm, the diameter of the threaded locking component is too small, and it is usually more prone to breakage, especially under high stress. The threaded locking component may not be able to withstand the pressure, resulting in damage to the threaded locking component and affecting the connection reliability of the first mounting base 411 and the second mounting base 412.

[0281] In some embodiments, d≥3.5mm ensures that the threaded locking component can withstand a certain pressure, reducing the probability of the threaded locking component breaking.

[0282] If d > 5mm, the diameter of the threaded locking part is too large, which usually makes it difficult to control the tightening force and can easily damage the first mounting base 411 and the second mounting base 412. At the same time, it will increase the contact area between the support structure 41b and the first mounting base 411 or the second mounting base 412, thereby producing abnormal noise.

[0283] In some embodiments, d≤5mm. This setting allows the threaded locking element to withstand a certain pressure to ensure the reliable connection between the first mounting base 411 and the second mounting base 412. It also avoids excessive tightening force of the threaded locking element, reducing the probability of damage to the first mounting base 411 and the second mounting base 412.

[0284] In some embodiments, 3.5mm ≤ d ≤ 5mm, for example, 3.5mm ≤ d ≤ 4mm, 4mm ≤ d ≤ 4.5mm, or 4.5mm ≤ d ≤ 5mm. Exemplary values ​​include d = 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4mm, 4.1mm, 4.2mm, 4.3mm, 4.4mm, 4.5mm, 4.6mm, 4.7mm, 4.8mm, 4.9mm, or 5mm.

[0285] This configuration allows the threaded locking element to have a sufficiently large diameter to ensure the reliability of the connection between the first mounting base 411 and the second mounting base 412. It also avoids the threaded locking element having an excessively large diameter, which would increase the contact area between the support structure 41b and the first mounting base 411 or the second mounting base 412, thus reducing the generation of abnormal noise.

[0286] In this application, for ease of description, the length of the threaded locking element is defined as L0. It is understood that the above definition is merely for the convenience of description and should not be used to limit the scope of protection of this application.

[0287] If L0 < 18mm, the length of the threaded locking part is too short, the torque characteristics are poor, it cannot withstand too much tensile and shear force, and it is easy to loosen and tilt, affecting the connection reliability of the first mounting base 411 and the second mounting base 412.

[0288] In some embodiments, L0 ≥ 18 mm, ensuring that the threaded locking component has a certain length and improving its torsional resistance.

[0289] If L0 > 25mm, the length of the threaded locking part is too long. Since the threaded locking part is a standard part, the longer the threaded locking part is, the larger the diameter of the threaded locking part will be, which will increase the contact area between the support structure 41b and the first mounting seat 411 or the second mounting seat 412, thus producing abnormal noise. At the same time, an excessively long threaded locking part also requires more materials and processing steps, resulting in higher costs.

[0290] In some embodiments, L0≤25mm. This setting allows the threaded locking component to have a certain length, improving its torsional resistance, and also avoids the threaded locking component from being too long, thus saving costs.

[0291] In some embodiments, 18mm ≤ L0 ≤ 25mm, for example, 18mm ≤ L0 ≤ 19mm, 19mm ≤ L0 ≤ 20mm, 20mm ≤ L0 ≤ 21mm, 21mm ≤ L0 ≤ 22mm, 22mm ≤ L0 ≤ 23mm, 23mm ≤ L0 ≤ 24mm, or 24mm ≤ L0 ≤ 25mm. For example, L0 = 18mm, 18.5mm, 19mm, 19.5mm, 20mm, 20.5mm, 21mm, 21.5mm, 22mm, 22.5mm, 23mm, 23.5mm, 24mm, 24.5mm, or 25mm, etc.

[0292] This design ensures that the threaded locking element has sufficient length to guarantee the reliable connection between the first mounting base 411 and the second mounting base 412. It also prevents the threaded locking element from being too long, which would result in an excessively large diameter. This, in turn, avoids increasing the contact area between the support structure 41b and the first mounting base 411 or the second mounting base 412, thus reducing the generation of abnormal noise.

[0293] In some embodiments, combined with Figures 21 to 23 As shown, the end face of the drive gear 43 away from the drive motor is provided with a rotating shaft 432, and the second mounting base is provided with a shaft hole 412c, in which the rotating shaft 432 is rotatably embedded.

[0294] This configuration allows for improved rotational stability of the drive gear 43 by utilizing the cooperation between the rotating shaft 432 and the shaft hole 412c.

[0295] Since the output shaft of the drive motor is typically inserted into the mounting hole of the drive gear 43 to connect the output shaft of the drive motor and the drive gear 43, a decrease in the depth to which the output shaft of the drive motor is inserted into the mounting hole of the drive gear 43 will result in a decrease in the depth to which the rotating shaft 432 is inserted into the shaft hole 412c. Furthermore, since the wall surface of the shaft hole 412c needs to have a draft angle, a decrease in the depth to which the rotating shaft 432 is inserted into the shaft hole 412c will result in an increase in the assembly clearance between the rotating shaft 432 and the shaft hole 412c, thereby affecting the rotational stability of the rotating shaft 432 relative to the shaft hole 412c.

[0296] Therefore, in some embodiments, as shown in the figure Figure 23 and Figure 24 As shown, the shaft hole 412c includes a first hole body 4121 and a second hole body 4122 that are interconnected. During assembly, the rotating shaft 432 passes through the second hole body 4122 and the first hole body 4121. The first hole body 4121 includes a bottom surface 41211 and a first side wall surface 41212 connected to the bottom surface 41211. The second hole body 4122 includes a second side wall surface 41221 connected to the first side wall surface 41212. The first side wall surface 41212 is perpendicular to the bottom surface 41211, and the connection between the second side wall surface 41221 and the second mounting base has a chamfer, such as a bevel or rounded corner.

[0297] With this configuration, when the depth of the rotating shaft 432 inserted into the shaft hole 412c changes, since the first hole sidewall 41212 is perpendicular to the hole bottom surface 41211, the fit clearance between the outer circumferential surface of the rotating shaft 432 and the first hole sidewall 41212 can always remain consistent. This ensures that the fit clearance between the rotating shaft 432 and the shaft hole 412c remains consistent, making the fit between the rotating shaft 432 and the shaft hole 412c more stable and less prone to shaking. This, in turn, improves the rotational stability of the drive gear 43, allowing the drive gear 43 to stably drive the rack structure 44 to slide, thus making the sliding door slide more smoothly and reducing abnormal situations such as jamming during operation.

[0298] Meanwhile, since the second hole sidewall 41221 and the connection between the second mounting base have chamfers, such as bevels or rounded corners, the second hole sidewall 41221 of the second hole body 4122 has a draft angle, which facilitates smooth demolding when the second mounting base is formed by injection molding, thus ensuring that the processing technology of the second mounting base is relatively simple.

[0299] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0300] Furthermore, the embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the content of this specification should not be construed as a limitation of this application, and the protection scope of this application should be determined by the appended claims.
