Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a vertical air conditioner. Background Art

[0002] Currently, the more common air conditioners are vertical air conditioners and wall-mounted air conditioners. As the name suggests, a vertical air conditioner is an air conditioner whose indoor unit is in the shape of a column and is placed on the ground in a "sitting" manner, while a wall-mounted air conditioner is an air conditioner whose indoor unit is suspended on the wall through components such as a back panel bracket.

[0003] The vertical air-conditioning indoor unit in the related art is usually provided with a sliding door that slides in the left and right directions at the air outlet. When the vertical air-conditioning indoor unit is not working, the sliding door is driven by the motion mechanism to slide to cover the air outlet, thereby preventing dust from entering the interior of the vertical air-conditioning indoor unit through the air outlet.

[0004] In order to improve the connection reliability between the sliding door and the motion mechanism, multiple screws are usually used to achieve the connection between the sliding door and the motion mechanism. Therefore, during assembly, the screws need to be tightened one by one, which makes the installation process of the sliding door cumbersome and the assembly efficiency low. Utility Model Content

Obviously, the exemplary embodiments described are only a portion of the embodiments of this application, not all of them. That is, the specific embodiments described herein are merely intended to explain this application and are not intended to limit this application.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the technical field of this application. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0077] As used in this application, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. 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 a first air outlet and a second air outlet are air outlets, but they are not the same air outlet.

[0078] 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 the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, unless otherwise specified, "plurality" means two or more.

[0079] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0080] In the description of this application, it should be noted that the singular forms "a", "an", and "the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

[0081] In addition, the term "and / or" used in this specification includes any and all combinations of the relevant listed items. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. That is, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0082] Related technology In order to prevent dust from entering the interior of the indoor unit through the air outlet of the indoor unit casing when the indoor unit of the vertical air conditioner is not working, a sliding door that can slide relative to the air outlet is usually provided at the air outlet, so that when the indoor unit is not working, the sliding door can be driven by a driving device to slide to cover the air outlet.

[0083] With the development of the field of vertical air-conditioning technology, users have gradually increased their requirements for the air output of vertical air-conditioning. For example, they hope that the casing of the indoor unit can form an air outlet of relatively large width to have the advantage of large air output, thereby bringing an increase in cooling or heating capacity, and then quickly changing the air temperature in a large range indoors, giving users a better user experience.

[0084] Since the vertical air conditioner is named because its indoor unit is in the shape of a column and is placed on the ground in a "sitting" manner, in order to ensure the cooling effect of the vertical air conditioner, the height of the indoor unit of the vertical air conditioner is usually about the same as the height of a human body. Therefore, if the indoor unit is to be miniaturized to facilitate the transportation of the indoor unit, the width of the indoor unit is usually reduced to achieve a miniaturized design of the indoor unit.

[0085] 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 and smaller, the width of the air outlet on the casing also becomes smaller and smaller, thereby failing to meet user requirements.

[0086] Moreover, the driving device in the related art is usually arranged 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.

[0087] Through experiments, the researchers and developers of this application discovered that when the width of the air outlet becomes larger, without increasing the width of the casing, the driving device will get closer and closer to other components in the casing, especially the heat exchanger, causing the driving device to be stopped by the heat exchanger during the sliding process, resulting in a relatively limited sliding stroke of the sliding door and the inability to fully open the air outlet. In this way, even if a large air outlet is formed, the air outlet volume cannot be increased, let alone the cooling capacity, and thus the air temperature in a large range of the room cannot be quickly changed.

[0088] In response to the design of large air outlets, the researchers of this application noticed that without increasing the width of the casing, the drive device would interfere with other components in the casing, especially the heat exchanger. Therefore, while maintaining the miniaturized design of the casing in terms of width and forming a large air outlet with a larger width, the researchers of this application further redesigned the position of the drive device, and set the drive device at the top and / or bottom of the sliding door in the height direction, so that the sliding door can have a larger distance between itself and other components in the casing, such as the heat exchanger, in its sliding direction, so that the sliding door has a larger sliding space to meet the coverage of the air outlet with a larger width, and can also avoid interference between the drive device and other components in the casing, to ensure that the sliding door can smoothly open or close the air outlet.

[0089] The following will be combined with the accompanying drawings of some embodiments of the present application to clearly and completely describe the technical solutions of some embodiments of the present application. Obviously, the embodiments described are only some embodiments of the present application, not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of this application.

[0090] The present invention discloses a vertical air conditioner that mainly uses a compressor, a condenser, an expansion valve, and an evaporator to perform a refrigeration cycle of the air conditioner. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0091] The compressor compresses high-temperature, high-pressure refrigerant gas and discharges the compressed gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, releasing heat into the surrounding environment through the condensation process.

[0092] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser to a lower-pressure liquid. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves cooling by utilizing the latent heat of evaporation to exchange heat with the material being cooled. Throughout this cycle, the air conditioner regulates the temperature of the indoor space.

[0093] The vertical air conditioner in this application includes an indoor unit and an outdoor unit, and the indoor unit is connected to the outdoor unit installed in an outdoor space through a pipe.

[0094] The outdoor unit may include a compressor, outdoor heat exchanger, outdoor fan, expander, and similar components of the refrigeration cycle. The indoor unit may also include an indoor heat exchanger and indoor fan. The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger functions as a condenser, the stand-alone air conditioner operates as a heater in heating mode. When the indoor heat exchanger functions as an evaporator, the stand-alone air conditioner operates as a cooler in cooling mode.

[0095] See also Figure 1 , Figure 1 Schematic diagram of the structure of a vertical air conditioner indoor unit provided in an embodiment of the present application. The embodiment of the present 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 an outdoor space through a pipe.

[0096] See also Figure 1 The indoor unit 100 provided in the embodiment of the present application includes a casing 10; the casing 10 can be a columnar structure, such as a circular columnar structure, a square columnar structure, etc., and the casing 10 has a length direction f1, a width direction f2 and a height direction f3.

[0097] like Figure 1 As shown, the casing 10 has a top and a bottom, and the direction from the top of the casing 10 to the bottom of the casing 10 is the height direction f3 of the casing 10; the casing 10 also has a left side and a right side arranged relatively to each other, wherein the direction from the left side of the casing 10 to the right side of the casing 10 is the width direction f2 of the casing 10; the casing 10 also has a front side and a rear side arranged relatively to each other, wherein the side of the casing 10 facing the user is the front side of the casing 10, and the direction from the front side of the casing 10 to the rear side of the casing 10 is the length direction f1 of the casing 10.

[0098] In some embodiments, 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.

[0099] In some embodiments, as Figures 1 to 3 As shown, the casing 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 casing 10, and the indoor air inlet 13 is located on the rear side of the casing 10.

[0100] In some embodiments, the indoor unit 100 includes a volute 20 , which is disposed in the inner cavity 11 , and has an air duct 21 connected to the first air outlet 12 and the indoor air inlet 13 , respectively.

[0101] 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 .

[0102] In some embodiments, the indoor unit 100 includes a fan (not shown, hereinafter referred to as the indoor fan), which is arranged in the inner cavity 11 and at least partially arranged 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.

[0103] Driven by the heat exchange fan, air enters the inner cavity 11 from the indoor air inlet 13 to exchange heat with the indoor heat exchanger. The air after heat exchange in 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.

[0104] In some embodiments, the outdoor unit includes an outdoor casing, an outdoor heat exchanger, and an outdoor fan.

[0105] In some embodiments, an outdoor housing is provided in the outdoor housing, wherein the outdoor fan and the outdoor heat exchanger are provided in the outdoor housing space.

[0106] In some embodiments, the outdoor housing is provided with an outdoor air inlet and an outdoor air outlet, wherein both the outdoor air inlet and the outdoor air outlet are in communication with the outdoor receiving space. The outdoor air inlet is used to introduce outdoor air into the outdoor receiving space, and the outdoor air outlet is used to draw air from the outdoor receiving space to the outside of the outdoor receiving space.

[0107] In some embodiments, the rotation of the outdoor fan causes outdoor air to enter the outdoor accommodation space from the outdoor air inlet and exchange heat with the outdoor heat exchanger, and the outdoor air after heat exchange flows out of the outdoor accommodation space from the outdoor air outlet.

[0108] In some embodiments, the outdoor unit further includes a compressor and a throttling device, and both the compressor and the throttling device are arranged in the outdoor accommodation space.

[0109] In some embodiments, the vertical air conditioner performs a refrigeration cycle of the vertical air conditioner by 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.

[0110] In some embodiments, the compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state, and the discharged refrigerant gas flows into the condenser.

[0111] 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.

[0112] In some embodiments, the throttling device expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0113] In some embodiments, the evaporator evaporates the refrigerant expanded in the throttling device and returns the refrigerant gas at a low temperature and low pressure state to the compressor.

[0114] In some embodiments, the evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the vertical type can adjust the temperature of the indoor space.

[0115] In some embodiments, among both the indoor heat exchanger and the outdoor heat exchanger, one is a condenser and the other is an evaporator, and when the indoor heat exchanger is used as a condenser, the stand-alone air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the stand-alone air conditioner is used as a cooler in a cooling mode.

[0116] In this application, if Figure 3 As shown, for ease of description, the width of the housing 10 in the 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 description of this application and should not be used to limit the scope of protection of this application.

[0117] If w1<w0 / 2, the width of the first air outlet 12 is too small, resulting in too small an air volume from the first air outlet 12, which makes it difficult for the indoor unit 100 to quickly change the air temperature in a large range indoors, and may easily bring a poor user experience.

[0118] In some embodiments, w1≥w0 / 2, thereby ensuring that the indoor unit 100 in the present application has a relatively large first air outlet 12, so that the air outlet volume of the indoor unit 100 can be increased, thereby bringing about an increase in cooling or heating, and further enabling the indoor unit 100 to quickly change the air temperature in a larger range indoors, thereby improving the user experience.

[0119] If w1>7w0 / 8, the internal installation space of the casing 10 in the width direction f2 becomes smaller, which is not conducive to the arrangement of various functional components of the indoor unit 100 in the inner cavity 11 of the casing 10.

[0120] In some embodiments, w1≤7w0 / 8. Such a setting can not only make the indoor unit 100 have a relatively large air outlet, but also facilitate the arrangement of various functional components of the indoor unit 100 in the inner cavity 11 of the casing 10.

[0121] 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. For example, w1=w0 / 2, 9w0 / 16, 5w0 / 8, 11w0 / 16, 3w0 / 4, 13w0 / 16, or 7w0 / 8.

[0122] Such a setting can enable the indoor unit 100 to have a first air outlet 12 that is large enough to increase the air outlet volume of the indoor unit 100, thereby quickly changing the air temperature in a larger range of the room; it can also avoid excessive reduction of the inner cavity 11 of the casing 10 while achieving a miniaturized design, thereby affecting the installation and arrangement of various functional components in the inner cavity 11, so as to facilitate the arrangement of various functional components in the inner cavity 11 of the casing 10.

[0123] 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. Therefore, when the indoor unit 100 is in operation, air heated by the heat exchanger, such as cooled air, enters the air duct 21 under the action of the fan, enters the first air outlet 12 through the second air outlet 22, and finally blows from the first air outlet 12 into the indoor space, thereby changing the air temperature of the indoor space, for example, lowering the air temperature of the indoor space.

[0124] In this application, for the convenience of description, the width of the second air outlet 22 in the width direction f2 of the casing 10 is defined as w2. It can be understood that the above definition is only for the convenience of description of this application, but should not be used to limit the scope of protection of this application.

[0125] If w2<2w0 / 5, the width of the second air outlet 22 is too small, which will limit the air flow, resulting in a weakened cooling or heating effect of the indoor unit 100, which may affect the heat dissipation efficiency and overall performance of the indoor unit 100, making the heat exchanger of the indoor unit 100 unable to fully play its role, which may affect the service life of the indoor unit 100.

[0126] In some embodiments, w2≥2w0 / 5, which can ensure that the indoor unit 100 has a larger air output, thereby accelerating the speed at which the indoor unit 100 changes the indoor air temperature and improving the user experience.

[0127] If w2>3w0 / 5, the width of the second air outlet 22 is too large, which may cause the airflow to be too dispersed, so that the cooling or heating effect of the indoor unit 100 is not as expected.

[0128] In some embodiments, w2≤3w0 / 5. This configuration allows the second air outlet 22 to provide a larger air flow rate, thereby improving the circulation of indoor air, making the indoor air fresher and improving indoor air quality, while also reducing energy consumption and noise.

[0129] 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.

[0130] Such a setting can increase the air volume while avoiding excessive dispersion of the air flow, so as to ensure the cooling or heating effect of the indoor unit 100; at the same time, it can also reduce energy consumption and noise.

[0131] In some embodiments, as Figure 4 As shown, the indoor unit 100 includes a sliding door 30 ; the sliding door 30 is disposed at the first air outlet 12 , and the sliding door 30 is used to slide open or close the first air outlet 12 .

[0132] That is, when the indoor unit 100 is operating, the sliding door 30 can open the first air outlet 12, and the first air outlet 12 is no longer blocked by the sliding door 30, so that the indoor unit 100 can blow air into the room; and when the indoor unit 100 is not operating, the sliding door 30 can close the first air outlet 12, and 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.

[0133] In some embodiments, as Figure 4 As shown, the indoor unit 100 includes a driving device 40, which is arranged in the inner cavity of the casing 10, and the driving device 40 is connected to the sliding door 30, so that the driving 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.

[0134] In some embodiments, the driving device 40 is located at the top and / or bottom of the sliding door 30 in the height direction f3 of the casing 10, that is, the driving device 40 can be located at the top of the sliding door 30 in the height direction f3 of the casing 10, or at the bottom of the sliding door 30 in the height direction f3 of the casing 10, or the driving device 40 includes a first driving mechanism 40a and a second driving mechanism 40b, the first driving mechanism 40a is set at the top of the sliding door 30 in the height direction f3 of the casing 10, and the second driving mechanism 40b is located at the bottom of the sliding door 30 in the height direction f3 of the casing 10, and the first driving mechanism 40a and the second driving mechanism 40b are both connected to the sliding door 30.

[0135] Arranging the driving device 40 at the top and / or bottom of the sliding door 30 in the height direction f3 can make the sliding door 30 and the first air outlet 12 at least partially overlap in the height direction f3 of the casing 10, so that the sliding door 30 has a larger distance from other components in the casing 10, such as the heat exchanger, in its sliding direction, and the sliding door 30 has a larger sliding space to meet the coverage of the first air outlet 12 with a larger width.

[0136] In this way, without increasing the width of the casing 10, a first air outlet 12 and a sliding door 30 with a relatively large width can be formed to increase the air outlet of the indoor unit 100, thereby increasing the cooling capacity, and enabling the indoor unit 100 to quickly change the air temperature in a larger range indoors, thereby improving the user experience; at the same time, it can also avoid interference between the drive device 40 and other components in the casing 10 (such as the heat exchanger) to ensure that the sliding door 30 can smoothly open or close the first air outlet 12.

[0137] In some embodiments, as Figure 3 and Figure 4As shown, the indoor unit 100 includes an air guide plate 50, which is rotatably arranged at the first air outlet 12 so that the air guide plate 50 can be used to adjust the air flow 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.

[0138] In some embodiments, the indoor unit 100 includes a power motor 60, which is arranged 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.

[0139] In the present application, the first air outlet 12 is formed with an inner wall 121 in the width direction f2 of the housing 10 . The inner wall 121 is spaced apart from the air guide plate 50 so that wind can pass through the gap between the inner wall 121 and the air guide plate 50 .

[0140] For ease of description, the minimum distance between the air guide plate 50 and the inner wall 121 in the width direction f2 of the housing 10 is defined as L1. It is understood that the above definition is only for the convenience of description of this application and should not limit the scope of protection of this application.

[0141] If L1<w1 / 5, the minimum distance between the air guide plate 50 and the inner wall 121 is too small, which easily causes the 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 lower, making it easier to produce condensation, and causing the condensation problem to become more serious.

[0142] In some embodiments, L1 ≥ w1 / 5, ensuring that the minimum distance between the air guide plate 50 and the inner wall 121 can be maintained within a relatively large range, reducing the concentration of cold air at the minimum distance between the air guide plate 50 and the inner wall 121, thereby reducing condensation.

[0143] If L1>3w1 / 4, the minimum distance between the air guide plate 50 and the inner wall 121 is too large, which will result in too few air guide plates 50, and the air guiding effect of the air guide plate 50 will not be obvious enough, and direct blowing may still occur.

[0144] In some embodiments, L1≤3w1 / 4. Such a setting can not only keep the minimum distance between the air guide plate 50 and the inner wall 121 within a relatively large range, reduce the concentration of cold air at the minimum distance between the air guide plate 50 and the inner wall 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, so that the air outlet is more uniform.

[0145] 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.

[0146] Such a setting can make the minimum distance between the air guide plate 50 and the inner wall 121 have a relatively large distance range, increase the minimum distance between the air guide plate 50 and the inner wall 121, thereby reducing the concentration of cold air between the air guide plate 50 and the inner wall 121, and further reducing the condensation on the air guide plate 50, reducing the amount of condensed water, and at the same time making the air outlet at the first air outlet 12 more uniform, allowing the air to be more evenly distributed in the room, achieving a more uniform indoor temperature distribution, and improving the cooling effect.

[0147] In some embodiments, L1 is the minimum distance between the air deflector 50 and the inner sidewall 121 in the width direction f2 when the air deflector 50 rotates to the limit position. The limit position is the position where the air deflector 50 cannot continue to rotate along the original rotation direction.

[0148] It can be understood that when the air guide plate 50 is rotated to the extreme 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 is rotated to a certain angle but has not reached the extreme position. By controlling the minimum distance between the air guide plate 50 and the inner wall 121 when it is rotated to the extreme position to be greater than or equal to one-fifth of the width of the first air outlet 12, it can be ensured that no matter how much the air guide plate 50 is rotated, 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 phenomenon on the air guide plate 50 and reducing the amount of condensed water.

[0149] In some embodiments, the inner sidewall 121 includes a first inner sidewall 121a and a second inner sidewall 121b that oppose each other in the width direction f2 of the housing 10. L1 is the minimum distance between the air deflector 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 deflector 50 and the second inner sidewall 121b in the width direction f2 of the housing 10 as L2. A direction perpendicular to the height direction f3 and perpendicular to the thickness direction of the air deflector 50 is also defined as a second direction f5.

[0150] It is understandable that the above definitions are only for the convenience of describing the present application, but should not be used to limit the scope of protection of the present application.

[0151] It can be understood that the wind guide plate 50 can swing to the right or to the left during the rotation process. Assume that the rightward swing of the wind guide plate 50 is a process in which one side of the wind guide plate 50 in the second direction f5 approaches the first inner wall 121a, and the other side of the wind guide plate 50 in the second direction f5 approaches the second inner wall 121b; then the leftward swing of the wind guide plate 50 is a process in which one side of the wind guide plate 50 in the second direction f5 approaches the second inner wall 121b, and the other side of the wind guide plate 50 in the second direction f5 approaches the first inner wall 121a; and vice versa.

[0152] It can be seen from this that during the rotation of the air guide plate 50, the minimum distance between the air guide plate 50 and the second inner wall 121b in the width direction f2 of the casing 10 will also be reduced, so that the cold air will converge and concentrate at the minimum distance between the air guide plate 50 and the second inner wall 121b, and condensation will occur.

[0153] To this end, in some embodiments, L2 ≥ w1 / 5; such a setting can enable the minimum distance between the air guide plate 50 and the second inner wall 121b to be controlled within a relatively large distance range, thereby increasing the minimum distance between the air guide plate 50 and the second inner wall 121b, thereby reducing the phenomenon of cold air concentrating at the minimum distance between the air guide plate 50 and the second inner wall 121b, and further reducing the condensation phenomenon on the air guide plate 50 and the amount of condensed water.

[0154] 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, which will cause the air guiding effect of the air guide plate 50 to be not obvious enough, and there may still be a direct blowing situation.

[0155] In some embodiments, L2≤3w1 / 4. Such a setting can not only ensure that the minimum distance between the air guide plate 50 and the second inner wall 121b can be maintained 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 wall 121b, thereby reducing condensation; it can also ensure that an appropriate number of air guide plates 50 are set at the first air outlet 12, so that the air outlet is more uniform.

[0156] 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.

[0157] Such a setting can make the minimum distance between the air guide plate 50 and the second inner wall 121b have a relatively large distance range, thereby increasing the minimum distance between the air guide plate 50 and the second inner wall 121b, thereby reducing the concentration of cold air between the air guide plate 50 and the second inner wall 121b, and further reducing the condensation on the air guide plate 50, reducing the amount of condensed water, and at the same time making the air outlet at the first air outlet 12 more uniform, allowing the air to be more evenly distributed in the room, achieving a more uniform indoor temperature distribution, and improving the cooling effect.

[0158] In some embodiments, the number of the 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. The multiple air guide plates 50 can be arranged in sequence along the height direction f3 of the housing 10, or can be arranged in sequence along the width direction f2 of the housing 10.

[0159] For example, the plurality of air deflectors 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 deflector 50 closest to the first inner sidewall 121a and the first inner sidewall 121a is L1, and the distance between the air deflector 50 closest to the second inner sidewall 121b and the second inner sidewall 121b is L2.

[0160] 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 through 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 driven to rotate simultaneously through the connecting rod.

[0161] In this application, if Figure 5 As shown, for ease of description, the height of the housing 10 in the 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 description of this application and should not be used to limit the scope of protection of this application.

[0162] 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.

[0163] In some embodiments, h1≥h0 / 2, thereby ensuring that the first air outlet 12 also has a larger size in the height direction f3 of the casing 10, so that the air output of the indoor unit 100 can be further improved, thereby enabling the indoor unit 100 to change the air temperature in a larger range indoors more quickly.

[0164] If h1>3h0 / 4, the first air outlet 12 will have a larger size in the height direction f3 of the casing 10, thereby increasing the overall thickness of the indoor unit 100 and the occupied space of the indoor unit 100, which is not conducive to the transportation of the indoor unit 100.

[0165] 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.

[0166] In some embodiments, h0 / 2≤h1≤3w0 / 4, for example, h0 / 2≤h1≤5h0 / 8 or 5h0 / 8≤h1≤3h0 / 4. For example, h1=h0 / 2, 9h0 / 16, 5h0 / 8, 11h0 / 16 or 3h0 / 4.

[0167] Such a setting can enable the indoor unit 100 to have a first air outlet 12 that is large enough to increase the air outlet volume of the indoor unit 100, thereby quickly changing the air temperature in a larger range of the room; it can also avoid the height of the first air outlet 12 being too high, which will cause the overall height of the indoor unit 100 to increase, thereby facilitating the control of the occupied space of the indoor unit 100, and further facilitating the transportation of the indoor unit 100.

[0168] In this application, for the convenience of description, the air volume of the first air outlet 12 is defined as Q. It can be understood that the above definition is only for the convenience of description of this application, but should not be used to limit the scope of protection of this application.

[0169] If Q < 1600m 3 / h, if the air output of the indoor unit 100 is too small, it may lead to poor indoor air circulation, easily cause indoor air pollution, and affect health. At the same time, it may also cause uneven indoor temperature, resulting in a decrease in the overall indoor comfort.

[0170] In some embodiments, Q≥1600m 3 / h, thereby ensuring the air outlet volume of the first air outlet 12, which can not only improve the circulation of indoor air, make the indoor air fresher, and help improve the indoor air quality; but also make the air flow more evenly, improve the indoor comfort, and reduce the "dead corner" phenomenon, that is, the problem of poor air flow in certain corners.

[0171] If Q>2000m 3 / h, if the air output of the indoor unit 100 is too large, it will lead to increased energy consumption and may also be accompanied by increased noise.

[0172] In some embodiments, Q≤2000m3 This configuration can not only allow the first air outlet 12 to have a relatively large air output, but also reduce energy consumption and noise.

[0173] 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.

[0174] Such a configuration can ensure that the first air outlet 12 has sufficient air outlet volume to accelerate the discharge of indoor hot air, thereby improving the circulation of indoor air, accelerating the cooling rate, and improving the cooling effect; and reducing energy consumption and noise.

[0175] In this application, for the convenience of description, the air supply angle of the first air outlet 12 is defined as α. It is understandable that the above definition is only for the convenience of description of this application, but should not be used to limit the scope of protection of this application.

[0176] If α is less than 90°, the airflow range may be restricted, resulting in poor indoor temperature uniformity.

[0177] In some embodiments, α≥90°, ensuring that the indoor unit 100 has a wide air supply range, enhancing indoor air circulation, and improving the cooling effect.

[0178] If α>150°, the cold air may be directly concentrated on one side of the room, while other areas are not fully covered by the cold air, resulting in uneven indoor temperature. For example, the area close to the first air outlet 12 may be too cold, while the area far from the first air outlet 12 may not feel cool enough.

[0179] In some embodiments, α≤150°. This configuration allows the indoor unit 100 to have a wide air outlet range while preventing the cold air from blowing directly toward a specific area indoors, thereby ensuring a cooling effect.

[0180] 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°. Exemplarily, α=90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, or 150°, etc.

[0181] Such an arrangement can make the wind blown out from the first air outlet 12 have a wider area, which is conducive to covering various positions in the room, thereby achieving a more uniform indoor temperature distribution and improving the cooling effect.

[0182] In this application, the air delivery distance of the first air outlet 12 is defined as the maximum distance that the air 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 description and should not be used to limit the scope of protection of this application.

[0183] If e is less than 15m, the air supply distance is short, which may cause excessive local wind force, causing some areas to feel strong wind while other areas cannot feel the cooling effect, resulting in poor indoor temperature uniformity.

[0184] In some embodiments, e≥15m, which enables the indoor unit 100 to have a longer blowing distance, thereby improving the heat exchange efficiency of the indoor unit 100.

[0185] If e>25m, it may lead to increased energy consumption and may also be accompanied by increased noise.

[0186] In some embodiments, e≤25m, which can enable the indoor unit 100 to have a longer blowing distance, thereby improving the circulation of indoor air and changing the indoor temperature.

[0187] 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.

[0188] Such an arrangement can provide the indoor unit 100 with a sufficient blowing distance, which is conducive to the wind spreading to various locations in the room, thereby achieving a more uniform indoor temperature distribution and improving the cooling effect; it can also reduce energy consumption and noise.

[0189] Since the width of the first air outlet 12 in the width direction f2 of the casing 10 is increased in the present application, the width of the sliding door 30 in the width direction f2 of the casing 10 will also be increased accordingly, and thus the weight of the sliding door 30 will also be increased accordingly.

[0190] For this reason, Figure 5 and Figure 6 As shown, the preferred driving device 40 of the present application includes a first driving mechanism 40a and a second driving mechanism 40b, wherein the first driving mechanism 40a is located at the top of the sliding door 30, and the second driving mechanism 40b is located at the bottom of the sliding door 30, and both the first driving mechanism 40a and the second driving mechanism 40b are connected to the sliding door 30.

[0191] Such a configuration can increase the overall driving force of the driving device 40, so that the driving device 40 can 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 casing 10 are respectively connected by the first driving mechanism 40a and the second driving mechanism 40b, compared with the sliding door 30 having only one end connected to the driving device 40, the connection area between the sliding door 30 and the driving device 40 can be increased, thereby improving the sliding stability of the sliding door 30 during sliding.

[0192] In some embodiments, combined Figure 5 、 Figure 6 and Figure 7 As shown, the driving device 40 includes an installation box 41, a driving motor 42, a driving gear 43 and a rack structure 44. Specifically, the first driving mechanism 40a and the second driving mechanism 40b both include an installation box 41, a driving motor 42, a driving gear 43 and a rack structure 44.

[0193] Among them, the installation box 41 is arranged in the inner cavity of the casing 10, the drive motor 42 and the power motor 60 are both installed in the installation box 41, the drive gear 43 is connected to the output shaft of the drive motor 42, the rack structure 44 is slidably arranged in the installation box 41, and the rack structure 44 is meshed with the drive gear 43, and the rack structure 44 is connected to the sliding door 30.

[0194] In this way, when the drive motor 42 starts running, the output shaft of the drive motor 42 drives the drive gear 43 to rotate, and the gear structure slides relative to the installation box 41 under the rotation of the drive gear 43, and synchronously drives the sliding door 30 to slide to open the first air outlet 12 or close the first air outlet 12.

[0195] Since the transmission between the gear and the rack is relatively smooth, the first drive mechanism 40a and the second drive mechanism 40b adopt the engagement of the drive gear 43 and the rack structure 44 to convert the rotational motion of the drive motor 42 into the sliding motion of the sliding door 30, which can reduce vibration and noise and improve the operating stability of the system; at the same time, since the transmission between the gear and the rack 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.

[0196] In addition, since the driving motor 42 and the power motor 60 are both installed in the installation box 41, the dual motors are integrated in the installation box 41, which can save installation space.

[0197] 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, and the rack structure 44 and the drive gear 43 are vertically meshed and connected. However, since the rack structure 44 is connected to the sliding door 30, especially under the premise of adopting the design of the large first air outlet 12 of the present application, the overall weight of the sliding door 30 is relatively heavy, and the rack structure 44 is subjected to a greater gravity from the sliding door 30, which is more likely to cause the rack structure 44 to deform downward, thereby causing the rack structure 44 to disengage from the drive gear 43, affecting the meshing between the rack structure 44 and the drive gear 43, and further affecting the sliding of the rack structure 44 and the sliding door 30.

[0198] To this end, in some embodiments, the axial direction of the driving gear 43 extends along the height direction f3 of the housing 10, that is, the axial direction of the driving gear 43 is parallel to the height direction f3 of the housing 10, and the driving gear 43 and the rack structure 44 are arranged along the length direction f1 of the housing 10, and the driving gear 43 and the rack structure 44 remain engaged in the length direction f1 of the housing 10.

[0199] Specifically, the drive gear 43 is provided with a plurality of gear teeth 431 arranged axially around the drive gear 43. The plurality of gear teeth 431 extend axially along the drive gear 43, that is, the plurality of gear teeth 431 extend along the height direction f3 of the housing 10. The rack structure 44 is provided with a plurality of rack teeth 44a on its surface in the length direction f1 of the housing 10. The plurality of 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.

[0200] Such a configuration makes it possible for the arrangement direction of the driving gear 43 and the rack structure 44 to no longer be 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 casing 10 due to the weight of the sliding door 30, the driving gear 43 and the rack structure 44 can still remain engaged to ensure that the driving gear 43 can smoothly drive the sliding of the rack structure 44, thereby ensuring that the sliding door 30 can slide smoothly and improving the sliding stability of the sliding door 30.

[0201] In some embodiments, combined Figure 6 、 Figure 8 and Figure 9 As shown, one of the mounting box 41 and the rack structure 44 is formed with a guide groove structure 41a, and the other of the mounting box 41 and the rack structure 44 is provided with a guide post structure 443, which is slidably embedded in the guide groove structure 41a. Thus, the cooperation between 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, and thus improving the sliding stability of the sliding door 30, allowing the sliding door 30 to slide more smoothly and reducing abnormalities such as jamming during operation of the sliding door 30.

[0202] Exemplarily, a guide groove structure 41a is formed on the surface of the mounting box 41 facing the rack structure 44, and a guide column structure 443 is provided on the surface of the rack structure 44 facing the mounting box 41. The guide column structure 443 can be slidably embedded in the guide groove structure 41a to provide guidance for the sliding of the rack structure 44.

[0203] In some embodiments, the materials of the installation box 41 and the rack structure 44 can be plastic, silicone, rubber and the like, so that the installation box 41 and the rack structure 44 can be formed by injection molding, which can make the processing technology of the installation box 41 and the rack structure 44 simpler and improve the processing efficiency.

[0204] In some embodiments, the guide groove structure 41a includes a first groove body 41a1 and a second groove body 41a2 that are interconnected along the depth direction. During assembly, the guide post structure 443 is inserted from the second groove body 41a2 into the first groove body 41a1. The first groove body 41a1 includes a groove bottom surface 41a11 and a first groove side wall surface 41a12 connected to the groove bottom surface 41a11. The second groove body 41a2 includes a second groove side wall surface 41a21 connected to the first groove side wall surface 41a12.

[0205] In some embodiments, the first groove body 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 body 41a1 is smaller than the groove opening width of the second groove body 41a2.

[0206] With such arrangement, when the rack structure 44 moves along the height direction f3 of the casing, since the first groove side wall 41a12 is perpendicular to the groove bottom surface 41a11, the fitting clearance between the outer peripheral surface of the guide column structure 443 and the first groove side wall 41a12 can always remain consistent and unchanged, thereby ensuring that the fitting clearance between the guide column structure 443 and the guide groove structure 41a remains consistent, so that the guide column structure 443 and the guide groove structure 41a fit more stably and are not easy to shake, and thus can play a more stable guiding role in the sliding of the rack structure 44, so as to further improve the sliding stability of the sliding door 30, make the sliding door 30 more smooth when sliding, and reduce abnormal conditions such as jamming of the sliding door 30 during operation.

[0207] At the same time, since the slot width of the first slot body 41a1 is smaller than the slot width of the second slot body 41a2, the second slot side wall surface 41a21 of the second slot body 41a2 has a draft angle, which facilitates smooth demolding when the installation box 41 is formed by injection molding, thereby ensuring that the processing technology of the installation box 41 is relatively simple.

[0208] In some embodiments, the first groove side wall surface 41a12 is perpendicular to the groove bottom surface 41a11, and in the opening direction of the guide groove structure 41a, the second groove side wall surface 41a21 gradually expands from the first groove side wall surface 41a11 to form an expanded groove in the second groove body.

[0209] With such arrangement, when the rack structure 44 moves along the height direction f3 of the casing 10, since the first groove side wall 41a12 is perpendicular to the groove bottom surface 41a11, the fitting clearance between the outer peripheral surface of the guide column structure 443 and the first groove side wall 41a12 can always remain consistent and unchanged, thereby ensuring that the fitting clearance between the guide column structure 443 and the guide groove structure 41a remains consistent, so that the guide column structure 443 and the guide groove structure 41a fit more stably and are not easy to shake, and thus can play a more stable guiding role in the sliding of the rack structure 44, so as to further improve the sliding stability of the sliding door 30, make the sliding door 30 more smooth when sliding, and reduce abnormal conditions such as jamming of the sliding door 30 during operation.

[0210] At the same time, since the second groove side wall of the second groove body 41a2 gradually expands from the first groove wall in the opening direction of the guide groove structure, so that the second groove body is formed into an expanded groove, the second groove side wall of the second groove body 41a2 has a draft angle, which facilitates smooth demolding when the installation box 41 is formed by injection molding, thereby ensuring that the processing technology of the installation box 41 is relatively simple.

[0211] In some embodiments, in the opening direction of the guide groove structure 41a, the second groove side wall surface 41a21 of the second groove body 41a2 can be gradually inclined from the first groove side wall surface 41a12 toward the direction away from the center of the second groove body 41a2 to form an inclined surface, so that the second groove side wall surface 41a21 of the second groove body 41a2 has a draft angle, which facilitates smooth demolding when the installation box 41 is formed by injection molding, thereby ensuring that the processing technology of the installation box 41 is relatively simple.

[0212] In other embodiments, in the opening direction of the guide groove structure 41a, the second groove side wall surface 41a21 of the second groove body 41a2 can be gradually inclined from the first groove side wall surface 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 surface 41a21 of the second groove body 41a2 has a draft angle, which facilitates smooth demolding when the installation box 41 is formed by injection molding, thereby ensuring that the processing technology of the installation box 41 is relatively simple.

[0213] In some embodiments, the mounting box 41 includes a first mounting seat 411 and a second mounting seat 412 connected to each other, the drive motor 42 is installed on the first mounting seat 411, the drive gear 43 is rotatably arranged on the second mounting seat 412 and is located between the first mounting seat 411 and the second mounting seat 412, and the rack structure 44 is slidably connected between the first mounting seat 411 and the second mounting seat 412.

[0214] With this arrangement, the rack structure 44 is located between the first mounting seat 411 and the second mounting seat 412 , and the rack structure 44 can be limited in the housing height direction f3 by the first mounting seat 411 and the second mounting seat 412 , which is beneficial to improving the sliding stability of the rack structure 44 .

[0215] In some embodiments, as Figure 9 As shown, the guide groove structure 41a includes a first guide groove 411a formed on the first mounting seat 411, and a second guide groove 412a formed on the second mounting seat 412, wherein the first guide groove 411a and the second guide groove 412a each 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.

[0216] In this way, a first guide column 443a can be provided at the upper part of the rack structure 44 in the height direction f3 of the casing to cooperate with the first guide groove 411a of the first mounting seat 411, and a second guide column 443b can be provided at the lower part of the rack structure 44 in the height direction f3 of the casing 10 to cooperate with the first guide groove 411a of the first mounting seat 411. Through the cooperation between the first guide column 443a and the first guide groove 411a, and the cooperation between the second guide column 443b and the second guide groove 412a, the sliding stroke of the rack structure 44 can be dually guided, thereby further improving the sliding stability of the rack structure 44.

[0217] In some embodiments, the first guide column 443a can be set as a cylinder. In this way, the friction generated between the first guide column 443a and the first guide groove 411a can be reduced, which is beneficial to reducing the sliding resistance of the rack structure 44, thereby facilitating smooth sliding of the sliding door 30. Moreover, since the contact surface is smooth, the first guide column 443a is not easy to scratch the first guide groove 411a.

[0218] Similarly, in some embodiments, the second guide column 443b can be set as a cylinder. In this way, the friction generated between the second guide column 443b and the second guide groove 412a can be reduced, which is beneficial to reducing the sliding resistance of the rack structure 44, thereby facilitating smooth sliding of the sliding door 30. Moreover, since the contact surface is smooth, the second guide column 443b is not easy to scratch the second guide groove 412a.

[0219] In the present application, the first guide groove 411a and the second guide groove 412a each include a first groove wall 411a1 and a second groove wall 411a2 extending along the sliding direction of the sliding door 30. The first groove wall 411a1 and the second groove wall 411a2 each include 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 referred to as a first direction f4. It is understood that the above definition is merely for the convenience of description of the present application and should not be used to limit the scope of protection of the present application.

[0220] In some embodiments, the first guide post 443 a and the second guide post 443 b have different sizes in the first direction f4 , and the first guide slot 411 a and the second guide slot 412 a have different sizes in the first direction f4 .

[0221] It can be understood that the first guide column 443a and the first guide groove 411a have approximately equal sizes in the first direction f4 so that the first guide column 443a can be inserted into the first guide groove 411a, and the second guide column 443b and the second guide groove 412a have approximately equal sizes in the first direction f4 so that the second guide column 443b can be inserted into the second guide groove 412a.

[0222] When the first guide post 443a and the second guide post 443b have different sizes in the first direction f4, and the first guide groove 411a and the second guide groove 412a have different sizes in the first direction f4, the first guide post 443a and the second guide groove 412a have different sizes in the first direction f4, and the second guide post 443b and the first guide groove 411a have different sizes in the first direction f4.

[0223] For example, in the first direction f4, the size of the first guide column 443a is larger than the size of the second guide column 443b. Then, in the first direction f4, the size of the first guide column 443a is larger than the size of the second guide groove 412a, and the size of the second guide column 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 casing 10, although the second guide column 443b can be inserted into the first guide groove 411a, the second guide column 443b cannot be inserted into the second guide groove 412a, thereby reminding the installer that the gear structure is installed upside down.

[0224] That is, during the assembly process, only when the first guide column 443a is embedded in the first guide groove 411a and the second guide column 443b is embedded in the second guide groove 412a, can the rack structure 44 be successfully assembled between the first mounting seat 411 and the second mounting seat 412, thereby preventing the rack structure 44 from being installed upside down and achieving a fool-proof installation effect.

[0225] In some embodiments, combined Figures 10 to 12 As shown, the first driving mechanism 40 a of the driving device is provided with a first connecting portion 441 , specifically, the rack structure 44 of the first driving mechanism 40 a is provided with a first connecting portion 441 , so as to provide a position for connecting with the sliding door 30 using the first connecting portion 441 .

[0226] 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 housing height direction f3. The first end plate 32 is arranged at an angle to the door body 31. For example, the first end plate 32 and the door body 31 are arranged at approximately 90 degrees. Of course, in other embodiments, the first end plate 32 and the door body 31 can also be arranged at other angles, such as 60 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, etc.

[0227] In some embodiments, the first end plate 32 may abut against the top of the first connection portion 441 in the height direction f3 of the casing, thereby enabling the first connection portion 441 to support the sliding door 30 .

[0228] In some embodiments, as Figure 13 and Figure 14 As shown, the indoor unit also includes a threaded fastener (not shown), the first connecting portion 441 is provided with a first connecting hole 4411, and the axial direction of the first connecting hole 4411 extends along the height direction f3 of the casing. For example, the axial direction of the first connecting hole 4411 is parallel to the height direction f3 of the casing, and the first end plate 32 is provided with a second connecting hole 321 that passes through the height direction f3 of the casing. 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, so that the first connecting hole 4411 and the second connecting hole 321 can be connected by the threaded fastener.

[0229] Such a configuration simplifies the connection between the sliding door 30 and the rack structure 44 of the first drive mechanism 40a, and since the sliding door 30 is abutted against the top of the first connecting portion 441 through the first end plate 32, the sliding door 30 is supported by the first connecting portion 441, which can share part of the gravity of the sliding door 30 and avoid the entire gravity of the sliding door 30 being applied to the threaded fasteners. This can ensure the connection reliability 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.

[0230] In addition, especially based on the design of the present application with a large first air outlet, that is, based on the design of increasing the width of the first air outlet in the direction of the width of the casing, as the width of the first air outlet in the direction of the width of the casing increases, the width of the sliding door 30 in the direction of the width of the casing will increase accordingly, and the weight of the sliding door 30 will also increase accordingly. By using the first end plate 32 to rest against the top of the first connecting portion 441, part of the gravity of the sliding door 30 can be shared, avoiding the entire gravity of the sliding door 30 being applied to the threaded fasteners, which is conducive to increasing the service life of the threaded fasteners and reducing the risk of the sliding door 30 detaching from the rack structure 44 and falling.

[0231] Alternatively, the threaded fastener may be a screw or a bolt.

[0232] It is understood that when the threaded fastener is a screw, the first connection hole 4411 is a threaded hole, and the second connection hole 321 can be a threaded hole or a blank hole. When the threaded fastener is a bolt, the first connection hole 4411 and the second connection hole 321 can both be threaded holes or blank holes. In this case, after the threaded fastener passes through the second connection hole 321 and the first connection hole 4411, a nut is used to thread the threaded fastener, thereby achieving a connection and fixation between the first connection hole 4411 and the second connection hole 321.

[0233] In some embodiments, as Figure 13 and Figure 14 As 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 column 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 column 4412, and when the first end plate 32 is provided with the first positioning column 4412, the first connecting part 441 is provided with the first positioning through hole 322.

[0234] The following takes the first end plate 32 provided with the first positioning through hole 322 and the first connecting portion 441 provided with the first positioning post 4412 as an example to describe the specific structure of the first positioning through hole 322 and the first positioning post 4412 as well as their positions and connection relationship.

[0235] The first positioning through hole 322 in the present application passes through the first end plate 32 along the housing height direction f3 , and the first positioning column 4412 extends along the housing height direction f3 . The first positioning column 4412 is disposed in the first positioning through hole 322 .

[0236] Therefore, during assembly, the first positioning through hole 322 on the sliding door 30 is mounted on the outer periphery of the first positioning column 4412 on the rack structure 44 of the first drive motor from top to bottom, so that precise positioning between the second connecting hole 321 and the first connecting hole 4411 can be achieved, and the second connecting hole 321 is aligned with the first connecting hole 4411, so that the threaded fasteners can be quickly passed through the second connecting hole 321 and the first connecting hole 4411, thereby improving the installation efficiency between the sliding door 30 and the first drive mechanism 40a.

[0237] In some embodiments, combined Figures 13 to 15 As shown, the second driving mechanism 40b is provided with a second connecting part 442, specifically, the rack structure 44 of the second driving mechanism 40b is provided with a second connecting part 442, and the second connecting part 442 and the first connecting part 441 are correspondingly arranged in the height direction f3 of the casing 10, so as to utilize the second connecting part 442 to provide a position for connection with the sliding door 30.

[0238] In some embodiments, the sliding door 30 further includes a second end plate 33 connected to the other end of the door body 31 in the height direction f3 of the housing 10. The second end plate 33 is arranged at an angle to the door body 31. For example, the second end plate 33 and the door body 31 are arranged at approximately 90 degrees. Of course, in other embodiments, the second end plate 33 and the door body 31 can also be arranged at other angles, such as 60 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, etc.

[0239] In some embodiments, one of the second end plate 33 and the second connecting portion 442 is provided with a second positioning column 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 the second positioning through hole 331, the second connecting portion 442 is provided with the second positioning column 4421, and when the second end plate 33 is provided with the second positioning column 4421, the second connecting portion 442 is provided with the second positioning through hole 331.

[0240] The following describes the specific structure, position, and connection relationship of the second positioning hole 331 and the second positioning column 4421 by taking the second end plate 33 provided with the second positioning hole 331 and the second connecting portion 442 provided with the second positioning column 4421 as an example.

[0241] The second positioning through hole 331 in the present application passes through the second end plate 33 along the housing height direction f3 , and the second positioning post 4421 extends along the housing height direction f3 . The second positioning post 4421 is disposed in the second positioning through hole 331 .

[0242] Therefore, during assembly, the second positioning through hole 331 on the sliding door 30 is sleeved on the outer periphery of the second positioning column 4421 on the rack structure 44 of the second drive machine from top to bottom to realize the connection between the sliding door 30 and the second drive mechanism 40b in the length and width directions of the casing. In the height direction f3 of the casing, the sliding door 30 is locked by the threaded fastener, so the second positioning through hole 331 can remain in the state of being sleeved on the outer periphery of the second positioning column 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.

[0243] Since the sliding door 30 is driven to slide by the first drive mechanism 40a and the second drive mechanism 40b, sometimes, it is inevitable that the drive motors of the first drive mechanism 40a and the second drive mechanism 40b will start asynchronously, resulting in the first drive mechanism 40a and the second drive mechanism 40b forming a pulling force at both ends of the sliding door 30, which will not only affect the sliding of the sliding door 30, causing jamming and noise, but may even cause damage to the sliding door 30.

[0244] To this end, combined 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 casing height direction f3, and the second end plate 33 is spaced apart from the second connecting portion 442 in the casing height direction f3, that is, a gap is formed between the surfaces of the second end plate 33 and the second connecting portion 442 facing each other.

[0245] In this way, when the driving motors of the first driving mechanism 40a and the second driving mechanism 40b are started asynchronously, the distance between the surfaces facing each other of the second end plate 33 and the second connecting part 442, combined with the non-fixed design of the second end plate 33 and the second connecting part 442 in the casing height direction f3, can allow the driving motor that is started first to drive one end of the sliding door 30 to slide first, thereby avoiding the first driving mechanism 40a and the second driving mechanism 40b from forming a pulling force at both ends of the sliding door 30, thereby ensuring that the sliding door 30 can slide smoothly, avoiding jamming and noise, and at the same time avoiding damage to the sliding door 30, thereby increasing the service life of the sliding door 30.

[0246] At the same time, the spacing between the second end plate 33 and the second connecting part 442 in the height direction f3 of the casing 10 can also provide a processing error space for the height of the sliding door 30 in the height direction f3 of the casing, thereby avoiding interference between the sliding door 30 and the second motion mechanism and affecting the installation of the sliding door 30.

[0247] In some embodiments, combined Figure 15 and Figure 16As shown, the second connection portion 442 is provided with a third connection hole 4422 , the axial direction of the third connection hole 4422 extends along the height direction f3 of the housing 10 , and the third connection hole 4422 is arranged opposite to the first connection hole 4411 in the height direction f3 of the housing.

[0248] With such an arrangement, even if the rack structure 44 of the second drive mechanism 40b is assembled to the mounting box 41 of the first drive mechanism 40a, at this time, the third connecting hole 4422 can be used as the first connecting hole 4411 for the threaded fastener to pass through, thereby realizing the connection and fixation of the rack structure 44 of the second drive mechanism 40b and the sliding door 30, thereby making the rack structures 44 of the first drive mechanism 40a and the second drive mechanism 40b interchangeable without the need to distinguish between them, and having strong versatility, which is conducive to improving the assembly flexibility of the first drive mechanism 40a, the second drive mechanism 40b and the sliding door 30.

[0249] It is understood that since the third connection hole 4422 can be used as the first connection hole 4411, the third connection hole 4422 and the first connection hole 4411 are of the same type. That is, when the first connection hole 4411 is a threaded hole, the third connection hole 4422 is also a threaded hole. When the first connection hole 4411 is a plain hole, the third connection hole 4422 is also a plain hole.

[0250] In some embodiments, the second end plate 33 is provided with a fourth connection hole 332 that passes through along the height direction f3 of the housing. The fourth connection hole 332 is arranged opposite to the second connection hole 321 along the height direction f3 of the housing 10 .

[0251] With such an arrangement, even if the sliding door 30 is turned upside down, that is, the second end plate 33 of the sliding door 30 is placed against the top of the first connecting portion 441, at this time, the fourth connecting hole 332 can be used as the second connecting hole 321 for the threaded fastener to pass through, and the sliding door 30 is connected and fixed to the first connecting portion 441, so that the sliding door 30 can be used up and down without distinguishing the direction, and has strong versatility, which is conducive to improving the assembly flexibility of the first drive mechanism 40a, the second drive mechanism 40b and the sliding door 30.

[0252] It is understood that since the fourth connection hole 332 can be used as the second connection hole 321, the fourth connection hole 332 and the second connection hole 321 are of the same type. That is, when the second connection hole 321 is a threaded hole, the fourth connection hole 332 is also a threaded hole. When the second connection hole 321 is a plain hole, the fourth connection hole 332 is also a plain hole.

[0253] The researchers and developers of this application have discovered through research that during the operation of the vertical air conditioner, unusual noises may occur from time to time. After repeated research, it was found that the unusual noises are mainly caused by the friction between the first mounting seat 411 and the second mounting seat 412. Specifically, during cooling or heating, the temperature at the first air outlet 12 varies greatly, especially based on the design of the large first air outlet 12 adopted in this application. The temperature variation at the first air outlet 12 is even greater, and the first mounting seat 411 and the second mounting seat 412 are very close to the first air outlet 12, which makes it easy for thermal expansion and contraction to occur, resulting in friction between the first mounting seat 411 and the second mounting seat 412, thereby generating unusual noises, such as a "clicking" noise.

[0254] To this end, in some embodiments, such as Figures 16 to 19 As shown, the first mounting seat 411 and / or the second mounting seat 412 is provided with a support structure 41b, which is located between the first mounting seat 411 and the second mounting seat 412. The support structure 41b is used to form a distance between the first mounting seat 411 and the second mounting seat 412. Therefore, when the first mounting seat 411 and the second mounting seat 412 expand and contract due to heat or cold, the distance between the first mounting seat 411 and the second mounting seat 412 can provide expansion space for the first mounting seat 411 and the second mounting seat 412, thereby reducing abnormal noise caused by friction caused by the thermal expansion and contraction of the first mounting seat 411 and the second mounting seat 412.

[0255] Exemplarily, when the first mounting seat 411 is provided with a support structure 41b, the support structure 41b abuts against the second mounting seat 412 to form a gap between the first mounting seat 411 and the second mounting seat 412, providing expansion space for the expansion of the first mounting seat 411 and the second mounting seat 412.

[0256] Optionally, a plurality of support structures 41b may be provided, for example, two, three, four, five, six, etc., to improve the support stability between the first mounting seat 411 and the second mounting seat 412, thereby making the overall structure of the mounting box 41 more stable. The plurality of support structures 41b may be arranged on the first mounting seat 411 along the sliding direction of the sliding door 30, with a regular arrangement and a stable structure.

[0257] In another exemplary embodiment, the second mounting seat 412 is provided with a support structure 41b, which abuts against the first mounting seat 411 to form a gap between the first mounting seat 411 and the second mounting seat 412, providing expansion space for the expansion of the first mounting seat 411 and the second mounting seat 412.

[0258] Optionally, a plurality of support structures 41b may be provided, for example, two, three, four, five, six, etc., to improve the support stability between the first mounting seat 411 and the second mounting seat 412, thereby further stabilizing the overall structure of the mounting box 41. The plurality of support structures 41b may be arranged on the second mounting seat 412 along the sliding direction of the sliding door 30, with a regular arrangement and a stable structure.

[0259] In another exemplary embodiment, the support structure 41b includes a first support portion 411b formed on the first mounting seat 411, and a second support portion 412b formed on the second mounting seat 412, the first support portion 411b and the second support portion 412b are both located between the first mounting seat 411 and the second mounting seat 412, and the first support portion 411b and the second support portion 412b abut against each other to form a distance between the first mounting seat 411 and the second mounting seat 412, providing expansion space for the expansion of the first mounting seat 411 and the second mounting seat 412.

[0260] In this application, for ease of description, the distance between the first mounting seat 411 and the second mounting seat 412 in the direction from the first mounting seat 411 to the second mounting seat 412, for example, in the housing height direction f3, is defined as a. It will be understood that the above definition is merely for the convenience of description of this application and is not intended to limit the scope of protection of this application.

[0261] If a is less than 1.0 mm, the distance between the first mounting seat 411 and the second mounting seat 412 is too small. When the expansion amount of the first mounting seat 411 and the second mounting seat 412 is relatively large, the first mounting seat 411 and the second mounting seat 412 may still contact and rub against each other, thereby generating abnormal noise.

[0262] In some embodiments, a≥1.0 mm, ensuring a certain distance between the first mounting seat 411 and the second mounting seat 412 to avoid contact and friction between the first mounting seat 411 and the second mounting seat 412 when a large expansion occurs.

[0263] If a>5.0 mm, a larger distance will be created between the first mounting seat 411 and the second mounting seat 412, thereby increasing the overall thickness of the mounting box 41 and the space occupied by the indoor unit, which is not conducive to the transportation of the indoor unit.

[0264] In some embodiments, a≤5.0mm. Such a setting can not only ensure a certain distance between the first mounting seat 411 and the second mounting seat 412, providing sufficient expansion space for the expansion of the first mounting seat 411 and the second mounting seat 412; it can also make the structure of the mounting box 41 more compact, which is conducive to reducing the space occupied by the mounting box 41 on the casing 10.

[0265] In some embodiments, 1.0 mm ≤ a ≤ 5.0 mm, for example, 1.0 mm ≤ a ≤ 2.0 mm, 2.0 mm ≤ a ≤ 3.0 mm, 3.0 mm ≤ a ≤ 4.0 mm, or 4.0 mm ≤ a ≤ 5.0 mm. For example, a = 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, or 5.0 mm.

[0266] Such a setting can ensure that there is a sufficient distance between the first mounting seat 411 and the second mounting seat 412, providing sufficient expansion space for the expansion of the first mounting seat 411 and the second mounting seat 412, reducing abnormal noise, and avoiding the situation where the distance between the first mounting seat 411 and the second mounting seat 412 is too large, resulting in an increase in the overall thickness of the mounting box 41, thereby avoiding the situation where the indoor unit occupies too much space and is not conducive to the transportation of the indoor unit.

[0267] In some embodiments, 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 of the first support portion 411b and the second support portion 412b may be 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.

[0268] In this way, through the cooperation between one end of the first support part 411b or the second support part 412b and the accommodating groove 411b1, initial positioning is provided for the connection between the first mounting seat 411 and the second mounting seat 412, thereby improving the assembly efficiency of the first mounting seat 411 and the second mounting seat 412; at the same time, there is no need to additionally set up a positioning column to cooperate with the accommodating groove, and it can also play a positioning role.

[0269] In some embodiments, the support structure 41b may include multiple first support parts 411b and multiple second support parts 412b, and a first support part 411b and a second support part 412b are abutted against each other, which is conducive to improving the support stability between the first mounting seat 411 and the second mounting seat 412, making the overall structure of the mounting box 41 more stable.

[0270] For example, multiple first support portions 411b can be arranged on the second mounting seat 412 along the sliding direction of the sliding door 30, and multiple second support portions 412b can be arranged on the second mounting seat 412 along the sliding direction of the sliding door 30, with regular arrangement and stable structure.

[0271] In some embodiments, the outer circumferential side of the support structure 41b is provided with reinforcing ribs 41b1 to enhance the structural strength of the support structure 41b. A plurality of reinforcing ribs 41b1 may be provided, and the plurality of reinforcing ribs 41b1 may be arranged at intervals along the circumference of the support structure 41b, thereby further enhancing the structural strength of the support structure 41b.

[0272] Exemplarily, the outer peripheral side surfaces of the first support portion 411 b and the second support portion 412 b are both provided with reinforcing ribs 41 b 1 to improve the structural strength of the first support portion 411 b and the second support portion 412 b.

[0273] In some embodiments, the indoor unit further includes a threaded locking member (not shown), and the first mounting base 411 and the second mounting base 412 can be fixedly connected via the threaded locking member, and the connection method is stable and reliable. The threaded locking member can be a screw or a bolt.

[0274] It can be understood that when only the first mounting seat 411 is provided with a support structure 41b, the support structure 41b is connected to the second mounting seat 412 through a threaded locking member; when only the second mounting seat 412 is provided with a support structure 41b, the support structure 41b is connected to the first mounting seat 411 through a threaded locking member; and when the support structure 41b includes a first support portion 411b formed on the first mounting seat 411 and a second support portion 412b formed on the second mounting seat 412, the first support portion 411b and the second support portion 412b are connected through a threaded locking member.

[0275] In this application, for the convenience of description, the diameter of the threaded locking member is defined as d. It is understandable that the above definition is only for the convenience of description of this application, but should not be used to limit the scope of protection of this application.

[0276] It is understood that the connection between the first mounting seat 411 and the second mounting seat 412 in this application is primarily achieved through a threaded locking member. If d is less than 3.5 mm, the threaded locking member has a small diameter and is generally prone to breakage. Especially under high stress, the threaded locking member may not be able to withstand the pressure, resulting in damage to the threaded locking member and affecting the connection reliability between the first mounting seat 411 and the second mounting seat 412.

[0277] In some embodiments, d≥3.5 mm, ensuring that the threaded locking member withstands a certain pressure and reducing the probability of the threaded locking member breaking.

[0278] If d>5mm, the diameter of the threaded locking member is too large, and it is usually difficult to control the tightening force, which can easily cause damage to the first mounting seat 411 and the second mounting seat 412. At the same time, it will also increase the contact area between the support structure 41b and the first mounting seat 411 or the second mounting seat 412, thereby generating abnormal noise.

[0279] In some embodiments, d≤5mm. Such a setting can not only make the threaded locking member withstand a certain pressure to ensure the connection reliability of the first mounting seat 411 and the second mounting seat 412; it can also avoid excessive tightening force of the threaded locking member, reducing the chance of damage to the first mounting seat 411 and the second mounting seat 412.

[0280] In some embodiments, 3.5 mm ≤ d ≤ 5 mm, for example, 3.5 mm ≤ d ≤ 4 mm, 4 mm ≤ d ≤ 4.5 mm, or 4.5 mm ≤ d ≤ 5 mm. For example, d = 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4 mm, 4.1 mm, 4.2 mm, 4.3 mm, 4.4 mm, 4.5 mm, 4.6 mm, 4.7 mm, 4.8 mm, 4.9 mm, or 5 mm.

[0281] Such a setting can ensure that the threaded locking member has a sufficiently large diameter to ensure the connection reliability between the first mounting seat 411 and the second mounting seat 412. It can also avoid the threaded locking member having a diameter that is too large, which will increase the contact area between the support structure 41b and the first mounting seat 411 or the second mounting seat 412, thereby reducing the generation of abnormal noise.

[0282] In this application, for the convenience of description, the length of the threaded locking member is defined as L0. It is understandable that the above definition is only for the convenience of description of this application, but should not be used to limit the scope of protection of this application.

[0283] If L0 is less than 18 mm, the length of the threaded locking member is too short, the torsional characteristics are poor, and it cannot withstand too much tension and shear force. It is also easy to loosen and tilt, affecting the connection reliability of the first mounting seat 411 and the second mounting seat 412 .

[0284] In some embodiments, L0 ≥ 18 mm, ensuring that the threaded locking member has a certain length and improving the anti-torsion property of the threaded locking member.

[0285] 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 length of the threaded locking part, the larger the diameter of the threaded locking part, which will increase the contact area between the support structure 41b and the first mounting seat 411 or the second mounting seat 412, and thus produce abnormal noise; at the same time, an overly long threaded locking part also requires more materials and processing steps, and the cost is higher.

[0286] In some embodiments, L0≤25mm. This setting can not only ensure that the thread locking member has a certain length and improve the torsion resistance of the thread locking member, but also prevent the thread locking member from being too long, saving costs.

[0287] In some embodiments, 18 mm≤L0≤25 mm, for example, 18 mm≤L0≤19 mm, 19 mm≤L0≤20 mm, 20 mm≤L0≤21 mm, 21 mm≤L0≤22 mm, 22 mm≤L0≤23 mm, 23 mm≤L0≤24 mm, or 24 mm≤L0≤25 mm. For example, L0=18 mm, 18.5 mm, 19 mm, 19.5 mm, 20 mm, 20.5 mm, 21 mm, 21.5 mm, 22 mm, 22.5 mm, 23 mm, 23.5 mm, 24 mm, 24.5 mm, or 25 mm, etc.

[0288] Such a setting can ensure that the threaded locking member has a sufficient length to ensure the connection reliability between the first mounting seat 411 and the second mounting seat 412. It can also avoid the threaded locking member being too long and causing the diameter of the threaded locking member to be too large, thereby avoiding the increase in the contact area between the support structure 41b and the first mounting seat 411 or the second mounting seat 412, and reducing the generation of abnormal noise.

[0289] In some embodiments, combined Figures 21 to 23 As shown, a rotating shaft 432 is provided on the end surface of the driving gear 43 away from the driving motor, and a shaft hole 412c is provided on the second mounting seat, and the rotating shaft 432 is rotatably embedded in the shaft hole 412c.

[0290] With such a configuration, the rotation stability of the driving gear 43 can be improved by utilizing the cooperation between the rotating shaft 432 and the shaft hole 412 c.

[0291] Since the output shaft of the drive motor is usually inserted into the mounting hole of the drive gear 43 to achieve the connection between the output shaft of the drive motor and the drive gear 43, when the depth of the output shaft of the drive motor inserted into the mounting hole of the drive gear 43 decreases, the depth of the rotation shaft 432 inserted into the shaft hole 412c will decrease. In addition, since the hole wall surface of the shaft hole 412c needs to be provided with a draft angle, when the depth of the rotation shaft 432 inserted into the shaft hole 412c decreases, the assembly clearance between the rotation shaft 432 and the shaft hole 412c will increase, thereby affecting the rotational stability of the rotation shaft 432 relative to the shaft hole 412c.

[0292] To this end, in some embodiments, as shown in FIG. Figure 23 and Figure 24As 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 hole bottom surface 41211 and a first hole side wall surface 41212 connected to the hole bottom surface 41211. The second hole body 4122 includes a second hole side wall surface 41221 connected to the first hole side wall surface 41212. The first hole side wall surface 41212 is perpendicular to the hole bottom surface 41211, and the connection between the second hole side wall surface 41221 and the second mounting seat is formed with a chamfer, such as a chamfered or rounded corner.

[0293] With such arrangement, when the depth of the rotating shaft 432 inserted into the shaft hole 412c fluctuates, since the first hole side wall surface 41212 is perpendicular to the hole bottom surface 41211, the fitting clearance between the outer peripheral surface of the rotating shaft 432 and the first hole side wall surface 41212 can always remain consistent and unchanged, thereby ensuring that the fitting clearance between the rotating shaft 432 and the shaft hole 412c remains consistent, so that the rotating shaft 432 and the shaft hole 412c fit more stably and are not easy to shake, thereby improving the rotation stability of the driving gear 43, so that the driving gear 43 can stably drive the rack structure 44 to slide, so that the sliding door can slide more smoothly, reducing abnormal conditions such as jamming of the sliding door during operation.

[0294] At the same time, since a chamfer, such as a bevel or a fillet, is formed at the connection between the second hole side wall surface 41221 and the second mounting seat, the second hole side wall surface 41221 of the second hole body 4122 has a draft angle, which facilitates smooth demolding when the second mounting seat is formed by injection molding, thereby ensuring that the processing technology of the second mounting seat is relatively simple.

[0295] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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.

[0296] In addition, the above-described embodiments only express several implementation methods of the present application, and their descriptions are relatively specific and detailed, but they should not be understood as limiting the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all fall within the scope of protection of the present application. Therefore, the content of this specification should not be understood as limiting the present application, and the scope of protection of the present application should be based on the appended claims.
