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] 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 "floor-standing" manner.

[0003] In order to improve the condensation problem of the air guide plate, related technologies include setting textures on the air guide plate to slow down the condensation rate of condensed water, and opening microporous structures on the air guide plate to reduce the generation of condensed water.

[0004] However, setting textures on the air guide plate cannot reduce the amount of condensed water, but can only slow down the speed at which the condensed water flows after condensation; and adding a microporous structure on the air guide plate will cause a large amount of wind to be blown away through the micropores, thereby weakening the air guiding effect of the air guide plate.

[0029] In some embodiments of the present application, the vertical air conditioner increases the minimum distance between the air guide plate and the inner side wall of the first air outlet by making the minimum distance between the air guide plate and the inner side wall of the first air outlet greater than or equal to one-fifth of the width of the first air outlet, thereby reducing the concentration of cold air between the air guide plate and the inner side wall of the first air outlet, thereby reducing condensation on the air guide plate, thereby reducing the amount of condensed water on the air guide plate, and also solving the problem of the air guide effect of the air guide plate being affected by the provision of a microporous structure on the air guide plate.

[0030] Some embodiments of the present application provide a vertical air conditioner, comprising:

[0031] Indoor unit,

[0032] Wherein, the indoor unit includes:

[0033] A housing having an inner cavity, and having a length direction, a width direction, and a height direction;

[0034] a volute, the volute being disposed in the inner cavity and having an air duct;

[0035] a fan, the fan being disposed in the inner cavity and at least partially disposed in the air duct;

[0036] a heat exchanger, the heat exchanger being disposed in the inner cavity;

[0037] a first air outlet, the first air outlet being formed on one side of the housing in the length direction, the first air outlet being in communication with the air duct, and the first air outlet being formed with an inner side wall in the width direction;

[0038] an air guide plate, the air guide plate being rotatably disposed at the first air outlet, the air guide plate being spaced apart from the inner side wall, and the air guide plate being used to adjust the airflow direction of the first air outlet; and

[0039] a drive motor, the drive motor being disposed in the inner cavity and connected to the air deflector, and being used to drive the air deflector to rotate;

[0040] The width of the first air outlet in the width direction is w1. After the air guide plate is rotated to a certain angle in the initial position, the minimum distance between the air guide plate and the inner wall in the width direction is L1, L1≥w1 / 5, and the initial position is configured as a position where the thickness direction of the air guide plate is parallel to the length direction.

[0041] In some embodiments of the present application, the vertical air conditioner increases the minimum distance between the air guide plate and the inner side wall of the first air outlet by making the minimum distance between the air guide plate and the inner side wall of the first air outlet greater than or equal to one-fifth of the width of the first air outlet, thereby reducing the concentration of cold air between the air guide plate and the inner side wall of the first air outlet, thereby reducing condensation on the air guide plate, thereby reducing the amount of condensed water on the air guide plate, and also solving the problem of the air guide effect of the air guide plate being affected by the provision of a microporous structure on the air guide plate.

[0042] As an optional embodiment, L1 is the minimum distance between the air guide plate and the inner wall in the width direction when the air guide plate rotates to the extreme position, and the extreme position is configured as the position where the air guide plate cannot continue to rotate along the original rotation direction.

[0043] With such a setting, by controlling the minimum distance between the air guide plate and the inner wall 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, it can be ensured that no matter how much the air guide plate is rotated, the concentration of cold air at the minimum distance between the air guide plate and the inner wall can be reduced, thereby reducing condensation on the air guide plate and reducing the amount of condensed water.

[0044] As an optional embodiment, the inner side wall includes a first inner side wall and a second inner side wall opposite to each other in the width direction, and L1 is the minimum distance between the air guide plate and the first inner side wall in the width direction;

[0045] In the width direction, the minimum distance between the air guide plate and the second inner side wall is L2, and L2≥w1 / 5.

[0046] Such a setting can control the minimum distance between the air guide plate and the second inner wall within a relatively large distance range, thereby increasing the minimum distance between the air guide plate and the second inner wall, thereby reducing the phenomenon of cold air concentrating at the minimum distance between the air guide plate and the second inner wall, thereby reducing condensation on the air guide plate and reducing the amount of condensed water.

[0047] As an optional embodiment, there are multiple air guide plates, and the multiple air guide plates are spaced apart along the width direction. Along the width direction, the minimum distance between the air guide plate closest to the inner wall among the multiple air guide plates and the inner wall in the width direction is configured as L1.

[0048] Such an arrangement can reduce the phenomenon of cold air converging and concentrating at the minimum distance between the air guide plate closest to the inner wall and the inner wall in the width direction of the casing, thereby reducing condensation on the air guide plate.

[0049] As an optional embodiment, the first air outlet is formed with a first water receiving platform in the height direction, and the first water receiving platform is rotatably connected to the bottom end of the air guide plate in the height direction;

[0050] The wind guide plate is provided with a water guide portion on its surface in the thickness direction. The water guide portion is located above the water receiving platform in the height direction. The water guide portion is used to guide the condensed water on the wind guide plate to the first water receiving platform.

[0051] With such an arrangement, during the operation of the indoor unit, the condensed water generated on the air guide plate can be promptly and quickly guided to the first water receiving platform through the water guide part, thereby reducing the probability that the condensed water is directly carried out of the indoor unit by the cold air blown out from the first air outlet, flowing to the ground or blowing towards the user, thereby improving the user experience.

[0052] As an optional embodiment, the indoor unit further includes a water receiving tray, which is disposed in the inner cavity and is located below the first water receiving platform in the height direction;

[0053] A first overflow hole is provided on the inner side wall near the first water receiving platform. In the height direction, the first overflow hole is at least partially higher than the first water receiving platform, and the first overflow hole is used to guide the condensed water on the first water receiving platform into the water receiving tray; and / or,

[0054] The first water receiving platform is provided with a second overflow hole, and the second overflow hole is used to guide the condensed water on the first water receiving platform into the water receiving tray.

[0055] With this arrangement, the condensed water on the first water receiving platform can flow to the water receiving tray through the first overflow hole and the second overflow hole, so as to prevent the condensed water on the first water receiving platform from overflowing and flowing to the ground, thereby further improving the user experience.

[0056] As an optional embodiment, when the inner side wall is provided with the first overflow hole, the first overflow hole includes a first hole wall surface and a second hole wall surface opposite to each other in the height direction, and the first hole wall surface is located above the second hole wall surface in the height direction;

[0057] In the height direction, the wall surface of the first hole is higher than the first water receiving platform, and the wall surface of the second hole is lower than or flush with the first water receiving platform.

[0058] Such a setting can not only ensure that the condensed water on the first water receiving platform can flow from the first overflow hole to the water receiving tray, but also ensure that the condensed water on the first water receiving platform can flow out from the first overflow hole without accumulating to a certain depth. In this way, the condensed water on the first water receiving platform can flow from the first water receiving platform into the first overflow hole in a timely manner, and then flow to the water receiving tray, thereby preventing the condensed water on the first water receiving platform from overflowing and flowing to the ground, further improving the user experience.

[0059] As an optional embodiment, the casing is provided with a second water receiving platform located at the first air outlet, the second water receiving platform extending along the width direction, and the second water receiving platform is rotatably connected to the air guide plate, and the second water receiving platform is located between the water guide portion and the first water receiving platform, and the water guide portion is used to guide the condensed water on the air guide plate to the second water receiving platform;

[0060] A third overflow hole is provided on the inner side wall near the second water receiving platform. In the height direction, the third overflow hole is at least partially higher than the second water receiving platform, and the third overflow hole is used to guide the condensed water on the second water receiving platform into the water receiving tray; and / or,

[0061] The second water receiving platform is provided with a fourth overflow hole, and the fourth overflow hole is used to guide the condensed water on the second water receiving platform into the water receiving tray.

[0062] With this arrangement, the condensed water on the second water receiving platform can flow to the water receiving tray through the third overflow hole and the fourth overflow hole, so as to prevent the condensed water on the second water receiving platform from overflowing and flowing to the ground, thereby further improving the user experience.

[0063] As an optional embodiment, when the inner side wall is provided with the third overflow hole, the third overflow hole includes a third hole wall surface and a fourth hole wall surface that are opposite to each other in the height direction, and the third hole wall surface is located above the fourth hole wall surface in the height direction;

[0064] In the height direction, the wall surface of the third hole is higher than the second water receiving platform, and the wall surface of the fourth hole is lower than or flush with the second water receiving platform.

[0065] Such a setting can not only ensure that the condensed water on the second water receiving platform can flow from the third overflow hole to the water receiving tray, but also ensure that the condensed water on the second water receiving platform can flow out from the third overflow hole without accumulating to a certain depth. In this way, the condensed water on the second water receiving platform can flow from the second water receiving platform into the third overflow hole in a timely manner, and then flow to the water receiving tray, thereby preventing the condensed water on the second water receiving platform from overflowing and flowing to the ground, further improving the user experience.

[0066] As an optional embodiment, a direction perpendicular to the height direction and perpendicular to the thickness direction of the air guide plate is configured as the first direction;

[0067] The wind deflector has a first side and a second side that are opposite to each other in the first direction. The second side and / or the first side are configured with a wave structure. The wave structure includes wave crests and wave troughs that are alternately arranged along the height direction.

[0068] With such a configuration, the wind blown out to the first air outlet can discretize the airflow under the action of the wave structure on the first side, and continue to be blown out from the first air outlet on the second side under the guidance of the wave structure on the second side, which has a better wind dispersion effect, can more effectively avoid the discomfort caused to the user by excessive concentration of air outlet, and improve the user's comfort.

[0069] At the same time, due to the existence of the trough, the wind blown out to the first air outlet can be blown into the room through the trough, thereby increasing the wind flow area of ​​the wind guide plate, reducing the contact between the wind blown out to the first air outlet and the wind guide plate, and thus reducing condensation on the wind guide plate.

[0070] As an optional embodiment, the thickness of the air deflector is h, and when the air deflector is rotated to the extreme position, the minimum distance between the wave crest and the inner side wall in the width direction is L3, and L3 ≥ h / 2;

[0071] The limit position is the position where the air guide plate cannot continue to rotate along the original rotation direction.

[0072] Such an arrangement can ensure that the air guide plate has a certain wind flow area, reduce the contact between the wind blown toward the first air outlet and the air guide plate, and thus reduce condensation on the air guide plate.

[0073] As an optional embodiment, the wave structure is constructed to have equal amplitude.

[0074] Such a setting can not only form wind-passing areas arranged at equal intervals along the height direction of the casing on the air guide plate, but also ensure that the sizes of each wind-passing area on the air guide plate remain roughly consistent, thereby evenly dispersing the airflow and avoiding the airflow converging at a certain position of the air guide plate, which is beneficial to reduce condensation on the air guide plate.

[0075] As an optional implementation, the thickness of the air guide plate is h, h≥w0 / 5, and / or, h≤w0 / 3.

[0076] Such a setting can reduce the wind-blocking effect of the wind guide plate and increase the wind-passing area of ​​the wind guide plate, thereby reducing the contact between the wind blown out to the first air outlet and the wind guide plate, and further reducing the condensation phenomenon on the wind guide plate; at the same time, the wind guide plate can also have a certain thickness to ensure the structural strength of the wind guide plate and extend the service life of the wind guide plate.

[0077] As an optional embodiment, the volute is provided with a second air outlet, the air duct is connected with the first air outlet through the second air outlet, and the air outlet angle of the second air outlet is θ, θ≤55°.

[0078] Such a setting can not only allow the indoor unit to have a wide air outlet range, but also prevent the cold air from being directly concentrated on a certain position or a certain air guide plate, thereby reducing the generation of condensation.

[0079] Compared with the prior art, the present invention has the following advantages:

[0080] The vertical air conditioner provided in the embodiment of the present application has an air guide plate of its indoor unit arranged at the first air outlet to adjust the airflow direction at the first air outlet, wherein the air guide plate and the inner side wall of the first air outlet in the width direction are spaced apart, and by making the minimum distance between the air guide plate and the inner side wall of the first air outlet greater than or equal to one-fifth of the width of the first air outlet, the minimum distance between the air guide plate and the inner side wall of the first air outlet can be increased to reduce the concentration of cold air between the air guide plate and the inner side wall of the first air outlet, thereby reducing the condensation phenomenon on the air guide plate, thereby reducing the amount of condensed water on the air guide plate, and at the same time, it can also solve the problem of affecting the air guiding effect of the air guide plate due to the arrangement of a microporous structure on the air guide plate.

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.

[0098] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0099] 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.

[0100] 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.

That is, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0104] The air guide plate of the vertical air conditioner indoor unit currently on the market is usually set at the air outlet of the casing to adjust the air outlet direction at the air outlet, thereby achieving the effect of expanding the air supply range or directional air supply.

[0105] When the indoor unit of a vertical air conditioner is in cooling operation, cold air blows into the room through the air outlet. At this time, the air guide plate is blown by the cold air, causing the temperature of the air guide plate to drop. When the hot air in the room encounters the surface of the air guide plate with lower temperature, the water vapor in it condenses when it gets cold, forming water mist or even condensing into larger water droplets, which adhere to the air guide plate or drip, causing condensation on the air guide plate. This not only affects the user experience, but also easily causes user complaints.

[0106] In related technologies, the condensation problem on the air guide plate is usually solved from the structural or procedural aspects, which mainly include the following solutions: adding anti-condensation procedures, adding heating devices in the air guide plate, changing the specific structure of the air guide plate, etc. to avoid the generation of condensation.

[0107] However, the above solutions have certain defects. For example, the anti-condensation effect of adding an anti-condensation program is poor, continuous heating of the air guide plate by a heating device will cause unnecessary energy waste, and setting textures on the surface of the air guide plate can only slow down the flow rate of condensed water after condensation but cannot reduce the amount of condensed water. Adding a microporous structure on the air guide plate will cause a large amount of wind to be blown away through the micropores, thereby weakening the air guiding effect of the air guide plate.

[0108] Therefore, condensation on the air guide plate is still a problem that is being avoided and solved in the current design and development of vertical air conditioners. In other words, how to avoid condensation on the air guide plate of a vertical air conditioner is still a technical problem that needs to be solved urgently by those skilled in the art.

[0109] Furthermore, the applicant has discovered that with the development of the field of vertical air-conditioning technology, users have gradually increased their requirements for the air output and air supply range of vertical air-conditioning indoor units. In designs with large air output, the increase in air output will lead to an increase in cooling capacity, resulting in a greater temperature difference at the air outlet and frequent intersection of hot and cold air, making it easier for condensation to form on the air guide plate, leading to a more serious condensation problem. In designs with a wide air supply range, the wide air supply range requires a larger rotation angle of the air guide plate. The larger the rotation angle of the air guide plate, the smaller the spacing between the air guide plate and the inner wall of the air outlet. The smaller the spacing between the air guide plate and the inner wall of the air outlet, the easier it is for cold air to converge and concentrate at the minimum spacing between the air guide plate and the inner wall of the air outlet, making the temperature of the air guide plate lower, which in turn makes it easier for condensation to form on the air guide plate, leading to a more serious condensation problem.

[0110] In view of this, an embodiment of the present application provides a vertical air conditioner that can improve the condensation problem of the air guide plate while ensuring the air guiding effect of the air guide plate.

[0119] Please refer again Figure 3 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 the indoor fan is used to provide power for the flow of air.

[0120] Driven by the heat exchange fan, air enters the inner cavity 11 from the heat exchange air inlet 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.

[0121] In some embodiments, the outdoor unit includes an outdoor casing 10 , an outdoor heat exchanger, and an outdoor fan.

[0122] In some embodiments, an outdoor housing space is provided in the outdoor casing 10 , wherein the outdoor fan and the outdoor heat exchanger are provided in the outdoor housing space.

[0123] In some embodiments, the outdoor housing 10 is provided with an outdoor air inlet and an outdoor air outlet, wherein both the outdoor air inlet and the outdoor air outlet are connected to the outdoor storage space. The outdoor air inlet is used to introduce outdoor air into the outdoor storage space, and the outdoor air outlet is used to draw air from the outdoor storage space to the outside of the outdoor storage space.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] Please refer again Figure 2 In some embodiments, the indoor unit 100 includes an air guide plate 30, which is rotatably disposed at the first air outlet 12 so that the air guide plate 30 can be used to adjust the airflow direction of the first air outlet 12, that is, to adjust the air outlet direction at the first air outlet 12, thereby achieving the effect of expanding the air supply range or directional air supply.

[0134] Please also refer to Figure 5-Figure 6In some embodiments, the indoor unit 100 includes a drive motor 40, which is disposed in the inner cavity 11 and connected to the air guide plate 30, so that the drive motor 40 can be used to drive the air guide plate 30 to rotate, thereby facilitating the rotation of the air guide plate 30 to adjust the airflow direction of the first air outlet 12.

[0135] Please also refer to Figure 3-Figure 4 In the present application, the first air outlet 12 is formed with an inner wall 111 in the width direction f2 of the casing 10, and the inner wall 111 is spaced apart from the air guide plate 30 so that wind can pass through the gap between the inner wall 111 and the air guide plate 30.

[0136] For ease of description, this application defines the width of the housing 10 in the width direction f2 as w0, the width of the first air outlet 12 in the width direction f2 as w1, and the minimum distance between the air guide plate 30 and the inner sidewall 111 in the width direction f2 of the housing 10 as L1. It should be understood that the above definitions are merely for the convenience of description and are not intended to limit the scope of protection of this application.

[0137] If L1 is less than w1 / 5, the minimum distance between the air guide plate 30 and the inner wall 111 is too small, which may easily cause the cold air to converge at the minimum distance between the air guide plate 30 and the inner wall 111, making the temperature of the air guide plate 30 lower, thereby making it easier for condensation to form on the air guide plate 30, resulting in a more serious condensation problem.

[0138] In some embodiments, L1 ≥ w1 / 5, ensuring that the minimum distance between the air guide plate 30 and the inner wall 111 can be maintained within a relatively large range, reducing the concentration of cold air at the minimum distance between the air guide plate 30 and the inner wall 111, thereby reducing condensation.

[0139] If L1>3w1 / 4, the minimum distance between the air guide plate 30 and the inner wall 111 is too large, which will result in too few air guide plates 30, and the air guiding effect of the air guide plate 30 will not be obvious enough, and direct blowing may still occur.

[0140] In some embodiments, L1≤3w1 / 4. Such a setting can not only keep the minimum distance between the air guide plate 30 and the inner wall 111 within a relatively large range, reduce the concentration of cold air at the minimum distance between the air guide plate 30 and the inner wall 111, thereby reducing condensation; it can also be set to ensure that an appropriate number of air guide plates 30 are provided at the first air outlet 12, so that the air outlet is more uniform.

[0141] 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.

[0142] Such a setting can control the minimum distance between the air guide plate 30 and the inner wall 111 within a relatively large distance range, thereby increasing the minimum distance between the air guide plate 30 and the inner wall 111, thereby reducing the concentration of cold air between the air guide plate 30 and the inner wall 111, and further reducing the condensation on the air guide plate 30, reducing the amount of condensed water, thereby improving the anti-condensation effect of the air guide plate 30; at the same time, it can make the air outlet at the first air outlet 12 more uniform, and the air can be more evenly distributed in the room, so as to achieve a more uniform indoor temperature distribution and improve the cooling effect.

[0143] In addition, compared with the method of adding a microporous structure on the air guide plate 30, since the technical solution of the present application does not require the opening of a microporous structure on the air guide plate 30, the present application can simultaneously take into account the air guiding effect and anti-condensation effect of the air guide plate 30.

[0144] Compared with the method of continuously heating the air guide plate 30 through a heating device, the technical solution of the present application can reduce energy waste while improving the condensation problem of the air guide plate 30, and because the present application saves the heating device, it can save costs.

[0145] 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.

[0146] Combine Figure 3 、 Figure 4 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] Combine Figure 2 and Figure 3 Such a configuration can enable the indoor unit 100 to have a sufficiently large first air outlet 12 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 and affect the installation and arrangement of various functional components in the inner cavity 11 while achieving a miniaturized design, so as to facilitate the arrangement of various functional components in the inner cavity 11 of the casing 10.

[0151] It can be understood that the larger the width of the first air outlet 12, the greater the air outlet volume at the first air outlet 12, which will make the temperature of the air guide plate 30 lower, and it will be more likely for condensation to occur on the air guide plate 30. The condensation problem is more prominent and severe. Therefore, based on the design of the present application with a large first air outlet 12, it is more urgent to solve the condensation problem of the air guide plate 30.

[0152] To this end, this application not only satisfies the relationship w1≥w0 / 2, but also satisfies the relationship L1≥w1 / 5. Such a setting can take into account the design of the large first air outlet 12 and the air guiding effect of the air guide plate 30, while effectively improving the condensation problem of the air guide plate 30, preventing the indoor unit 100 from blowing water, and improving the user experience.

[0153] In the present application, the initial position of the air guide plate 30 is configured as a position where the thickness direction of the air guide plate 30 is parallel to the length direction f1 of the casing 10, and the limit position of the air guide plate 30 is a position where the air guide plate 30 cannot continue to rotate along the original rotation direction.

[0154] It can be understood that when the air guide plate 30 starts to rotate from the initial position, the minimum distance between the air guide plate 30 and the inner wall 111 in the width direction f2 of the casing 10 will gradually decrease until the air guide plate 30 rotates to the extreme position, and the minimum distance between the air guide plate 30 and the inner wall 111 in the width direction f2 of the casing 10 reaches the minimum value.

[0155] In some embodiments, L1 is the minimum distance between the air guide plate 30 and the inner wall 111 in the width direction f2 of the casing 10 after the air guide plate 30 is rotated from the initial position to a certain angle, for example, 1°, 2°, 5°, 6°, 8°, 10°, 15°, 20°, 30°, 35°, 40°, etc.

[0156] In this way, by controlling the minimum distance between the air guide plate 30 and the inner wall 111 after it is rotated a certain angle from the initial position to be greater than or equal to one-fifth of the width of the first air outlet 12, it is possible to avoid the minimum distance between the air guide plate 30 and the inner wall 111 in the width direction f2 of the casing 10 being too small after the air guide plate 30 is rotated a certain angle, thereby reducing the cold air concentration phenomenon at the minimum distance between the air guide plate 30 and the inner wall 111 after the air guide plate 30 is rotated a certain angle from the initial position, thereby reducing the condensation phenomenon on the air guide plate 30 and reducing the amount of condensed water.

[0157] In some embodiments, L1 is the minimum distance between the air deflector 30 and the inner wall 111 in the width direction f2 when the air deflector 30 rotates to the extreme position.

[0158] In this way, by controlling the minimum distance between the air guide plate 30 and the inner wall 111 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 30 is rotated, the cold air can be reduced from concentrating at the minimum distance between the air guide plate 30 and the inner wall 111, thereby reducing the condensation phenomenon on the air guide plate 30 and reducing the amount of condensed water.

[0159] See also Figure 3 In some embodiments, the inner sidewall 111 includes a first inner sidewall 111a and a second inner sidewall 111b that are opposed to each other in the width direction f2 of the housing 10. L1 is the minimum distance between the air deflector 30 and the first inner sidewall 111a in the width direction f2 of the housing 10. For ease of description, this application defines the minimum distance between the air deflector 30 and the second inner sidewall 111b in the width direction f2 of the housing 10 as L2, and also defines a direction perpendicular to the height direction f3 and perpendicular to the thickness direction of the air deflector 30 as a first direction f4.

[0160] 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.

[0161] It can be understood that the wind guide plate 30 can swing to the right or to the left during the rotation process. Assume that the rightward swing of the wind guide plate 30 is a process in which one side of the wind guide plate 30 in the first direction f4 approaches the first inner wall 111a, and the other side of the wind guide plate 30 in the first direction f4 approaches the second inner wall 111b; then the leftward swing of the wind guide plate 30 is a process in which one side of the wind guide plate 30 in the first direction f4 approaches the second inner wall 111b, and the other side of the wind guide plate 30 in the first direction f4 approaches the first inner wall 111a; and vice versa.

[0162] It can be seen from this that during the rotation of the air guide plate 30, the minimum distance between the air guide plate 30 and the second inner wall 111b 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 30 and the second inner wall 111b, and condensation will occur.

[0163] To this end, in some embodiments, L2 ≥ w1 / 5; such a setting can enable the minimum distance between the air guide plate 30 and the second inner wall 111b to be controlled within a relatively large distance range, thereby increasing the minimum distance between the air guide plate 30 and the second inner wall 111b, thereby reducing the phenomenon of cold air concentrating at the minimum distance between the air guide plate 30 and the second inner wall 111b, thereby reducing the condensation phenomenon on the air guide plate 30 and reducing the amount of condensed water.

[0164] If L2>3w1 / 4, the minimum distance between the air guide plate 30 and the second inner wall 111b will be too large, resulting in too few air guide plates 30, which will cause the air guiding effect of the air guide plate 30 to be not obvious enough, and there may still be a direct blowing situation.

[0165] In some embodiments, L2≤3w1 / 4. Such a setting can not only ensure that the minimum distance between the air guide plate 30 and the second inner wall 111b can be maintained within a relatively large range, reducing the concentration of cold air at the minimum distance between the air guide plate 30 and the second inner wall 111b, thereby reducing condensation; it can also ensure that an appropriate number of air guide plates 30 are set at the first air outlet 12, so that the air outlet is more uniform.

[0166] 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.

[0167] Such a setting can make the minimum distance between the air guide plate 30 and the second inner wall 111b have a relatively large distance range, thereby increasing the minimum distance between the air guide plate 30 and the second inner wall 111b, thereby reducing the concentration of cold air between the air guide plate 30 and the second inner wall 111b, and further reducing the condensation on the air guide plate 30, 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.

[0168] In some embodiments, the number of the air guide plates 30 may be one or more, and may be designed accordingly based on the actual size of the first air outlet 12. The plurality of air guide plates 30 may be arranged sequentially along the height direction f3 of the housing 10, or may be arranged sequentially along the width direction f2 of the housing 10.

[0169] For example, multiple air deflectors 30 are rotatably mounted at the first air outlet 12 and arranged sequentially along the width direction f2 of the housing 10. To facilitate simultaneous rotation of the multiple air deflectors 30, the multiple air deflectors 30 can be connected as a whole via a connecting rod. When the drive motor 40 drives one of the air deflectors 30 to rotate, the connecting rod simultaneously drives all of the air deflectors 30 to rotate.

[0170] Such a setting allows multiple air guide plates 30 to rotate through the same drive motor 40, which can save the use of motors, help save costs, and reduce the space occupied by the drive motor 40 in the internal space of the casing 10, thereby facilitating the miniaturization design of the indoor unit 100.

[0171] Furthermore, when the multiple air deflectors 30 rotate, they typically swing synchronously to the right or left. The air deflector 30 closest to the inner sidewall 111 among the multiple air deflectors 30 typically has the smallest distance from the inner sidewall 111 in the width direction f2 of the housing 10. The distance between any two adjacent air deflectors 30 in the width direction f2 of the housing 10 typically remains constant, and the distance between any two adjacent air deflectors 30 in the width direction f2 of the housing 10 typically does not decrease. Therefore, cold air typically does not converge between any two adjacent air deflectors 30.

[0172] To this end, in some embodiments, along the width direction f2 of the casing 10 , the minimum distance between the air deflector 30 closest to the inner wall 111 among the plurality of air deflectors 30 and the inner wall 111 along the width direction f2 of the casing 10 is configured to be L1.

[0173] More specifically, along the width direction f2 of the casing 10, the distance between the air guide plate 30 closest to the first inner wall 111a among the multiple air guide plates 30 and the first inner wall 111a is configured as L1, and the distance between the air guide plate 30 closest to the second inner wall 111b among the multiple air guide plates 30 and the second inner wall 111b is configured as L2.

[0174] Such a configuration can reduce the phenomenon of cold air converging and concentrating at the minimum distance between the air guide plate 30 closest to the inner wall 111 and the inner wall 111 in the width direction f2 of the casing 10, thereby reducing condensation on the air guide plate 30.

[0175] In the present application, the wind deflector 30 has a first side and a second side disposed opposite each other in the first direction f4. The first side can be disposed closer to the volute 20 than the second side, in which case the first side serves as the windward side and the second side serves as the leeward side. Alternatively, the second side can be disposed closer to the volute 20 than the first side, in which case the second side serves as the windward side and the first side serves as the leeward side.

[0176] The specific structure of the wind deflector 30 will be further described in detail below by taking the first side as the windward side and the second side as the leeward side as an example.

[0177] See also Figure 5 and Figure 6 In some embodiments, the first side is configured with a wave structure including wave crests 30a and wave troughs 30b alternately arranged along the height direction f3.

[0178] With such a configuration, the wind blown out to the first air outlet 12 can discretize the airflow under the action of the wave structure, which has a good wind dispersion effect, avoids the discomfort caused to the user by excessive concentration of the wind, and improves the user's comfort; at the same time, due to the existence of the trough 30b, the wind passing area of ​​the wind guide plate 30 can be increased, reducing the contact between the wind blown out to the first air outlet 12 and the wind guide plate 30, thereby reducing the condensation phenomenon on the wind guide plate 30.

[0179] In other embodiments, the second side is configured with a wave structure including wave crests 30a and wave troughs 30b alternately arranged along the height direction f3.

[0180] With such a configuration, the wind blown out to the first air outlet 12 can discretize the airflow under the action of the wave structure, which has a good wind dispersion effect, avoids the discomfort caused to the user by excessive concentration of the wind, and improves the comfort of the user; at the same time, due to the existence of the trough 30b, the wind blown out to the first air outlet 12 can be blown into the room through the trough 30b, thereby increasing the wind flow area of ​​the wind guide plate 30, reducing the contact between the wind blown out to the first air outlet 12 and the wind guide plate 30, and thus reducing the condensation phenomenon on the wind guide plate 30.

[0181] In some further embodiments, both the first side and the second side are configured with a wave structure, wherein the wave structure includes wave crests 30a and wave troughs 30b alternately arranged along the height direction f3.

[0182] With such a configuration, the wind blown out to the first air outlet 12 can discretize the airflow under the action of the wave structure on the first side, and continue to be blown out from the first air outlet 12 on the second side under the guidance of the wave structure on the second side, which has a better wind dispersion effect, can more effectively avoid the discomfort caused to the user by excessive concentration of air outlet, and improve the user's comfort.

[0183] At the same time, because there are troughs 30b on both the first side and the second side, the wind flow area of ​​the wind guide plate 30 can be maximized, further reducing the contact between the wind blown toward the first air outlet 12 and the wind guide plate 30, thereby reducing condensation on the wind guide plate 30.

[0184] Combine Figure 3 、 Figure 5 and Figure 6 In the present application, for the convenience of description, the thickness of the air guide plate 30 is defined as h, and the minimum distance between the crest 30a and the inner wall 111 in the width direction f2 when the air guide plate 30 is rotated to the extreme position is defined as L3. It can be understood that the above definitions are only for the convenience of description of the present application, but should not be used to limit the scope of protection of the present application.

[0185] If h<w0 / 5, the thickness of the air guide plate 30 is relatively thin, resulting in insufficient structural strength of the air guide plate 30 and being easily damaged.

[0186] In some embodiments, h≥w0 / 5, ensuring that the air guide plate 30 has a certain thickness to ensure the structural strength of the air guide plate 30.

[0187] If h>w0 / 3, the thickness of the air guide plate 30 is relatively large, which can easily block the wind blowing toward the first air outlet 12 and affect the air outlet of the first air outlet 12. This will not only affect the speed at which the indoor unit 100 changes the indoor air temperature, but also affect the user experience.

[0188] In some embodiments, h≤w0 / 3. Such a setting can not only make the air guide plate 30 have a certain thickness to ensure the structural strength of the air guide plate 30 and extend the service life of the air guide plate 30; it can also reduce the wind blocking effect of the air guide plate 30 to ensure the air outlet of the first air outlet 12, and can quickly change the air temperature in a larger range in the room, thereby improving the user experience.

[0189] In some embodiments, w0 / 5≤h≤w0 / 3, for example, w0 / 5≤h≤7w0 / 30, 7w0 / 30≤h≤4w0 / 15, 4w0 / 15≤h≤3w0 / 10, or 3w0 / 10≤h≤w0 / 3. For example, h=w0 / 5, 13w0 / 60, 7w0 / 30, w0 / 4, 4w0 / 15, 17w0 / 60, 3w0 / 10, 19w0 / 60, or w0 / 3.

[0190] Such a setting can reduce the wind-blocking effect of the wind guide plate 30 and increase the wind-passing area of ​​the wind guide plate 30, thereby reducing the contact between the wind blown toward the first air outlet 12 and the wind guide plate 30, and further reducing the condensation phenomenon on the wind guide plate 30; at the same time, the wind guide plate 30 can also have a certain thickness to ensure the structural strength of the wind guide plate 30 and extend the service life of the wind guide plate 30.

[0191] If L3 < h / 2, the cold air will easily converge and concentrate at the minimum distance between the crest 30 a and the inner wall 111 , thereby easily causing condensation on the air guide plate 30 .

[0192] Combine Figure 2 、 Figure 3 In some embodiments, L3 ≥ h / 2, ensuring that the air guide plate 30 has a certain wind flow area, reducing the contact between the wind blown toward the first air outlet 12 and the air guide plate 30, thereby reducing condensation on the air guide plate 30.

[0193] If L3>10h / 7, the minimum distance between the air guide plate 30 and the inner wall 111 is too large, which will result in too few air guide plates 30, and the air guiding effect of the air guide plate 30 will not be obvious enough, and the user may still be blown directly.

[0194] In some embodiments, L3 ≤ 10h / 7. This configuration can prevent cold air from converging at the minimum distance between the wave crest 30a and the inner wall 111, thereby reducing condensation on the air guide plate 30; it can also ensure that an appropriate number of air guide plates 30 are provided at the first air outlet 12, thereby achieving more uniform air discharge.

[0195] In some embodiments, h / 2≤L3≤10h / 7, for example, h / 2≤L3≤2h / 3, 2h / 3≤L3≤3h / 4, 3h / 4≤L3≤h, h≤L3≤8h / 7, 8h / 7≤L3≤9h / 7, or 9h / 7≤L3≤10h / 7. Exemplarily, L3=h / 2, 7w0 / 12, 2h / 3, 17h / 24, 3h / 4, 7h / 8, h, 15h / 14, 8h / 7, 17h / 14, 9h / 7, 19h / 14, or 10h / 7, etc.

[0196] Such a setting can control the minimum distance between the peak 30a and the inner wall 111 over a relatively large distance range, increase the efficiency of cold air passing through the minimum distance between the peak 30a and the inner wall 111, avoid the cold air from converging and concentrating at this position, and thus help reduce condensation on the air guide plate 30; at the same time, it can make the air outlet at the first air outlet 12 more uniform, and make the air more evenly distributed in the room, so as to achieve a more uniform indoor temperature distribution and improve the cooling effect.

[0197] Please refer again Figure 5 and Figure 6 In some embodiments, the number of the wave crests 30a and the wave troughs 30b can be set to multiple, multiple wave crests 30a and multiple wave troughs 30b, then the first side and / or the second side of the air guide plate 30 is formed with multiple wave troughs 30b arranged along the height direction f3 of the casing 10, and the more the number of wave troughs 30b is, the more the number of wind-passing areas on the air guide plate 30 is, and the larger the wind-passing area of ​​the air guide plate 30 is, thereby further reducing the contact between the wind blown out to the first air outlet 12 and the air guide plate 30, and thus greatly improving the condensation phenomenon on the air guide plate 30.

[0198] In some embodiments, the wave structure is configured with equal amplitude. This arrangement not only forms evenly spaced airflow areas on the air guide plate 30 along the height direction f3 of the housing 10, but also ensures that the sizes of the airflow areas on the air guide plate 30 remain roughly consistent, thereby evenly dispersing the airflow and preventing it from converging at a specific location on the air guide plate 30, thereby reducing condensation on the air guide plate 30.

[0199] In addition, designing the wave structure to have equal amplitude can make the processing of the wind guide plate 30 more convenient and easier to achieve.

[0200] In some embodiments, the volute 20 is provided with a second air outlet, and the air duct 21 is connected to the first air outlet 12 through the second air outlet. 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, 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.

[0201] In the present application, for the convenience of description, the air outlet angle of the second air outlet is defined as θ. It can be understood that the above definition is only for the convenience of description of the present application, but should not be used to limit the scope of protection of the present application.

[0202] If θ is less than 25°, the air outlet angle of the second air outlet 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.

[0203] In some embodiments, θ≥25°, which ensures that the indoor unit 100 has a wide air supply range, strengthens indoor air circulation, improves cooling effect, and is conducive to improving user experience.

[0204] If θ>55°, the outlet angle of the second air outlet is too large, which may cause uneven air supply and may cause the cold air to be directly concentrated on a certain position of the air guide plate 30 or a certain air guide plate 30, thereby easily causing condensation.

[0205] In some embodiments, θ≤55°. This configuration allows the indoor unit 100 to have a wide air outlet range while preventing cold air from being blown directly onto a certain position of the air guide plate 30 or a certain air guide plate 30, thereby reducing the generation of condensation.

[0206] In some embodiments, 25°≤θ≤55°, for example, 25°≤θ≤27°, 27°≤θ≤29°, 29°≤θ≤31°, 31°≤θ≤33°, 33°≤θ≤35°, 35°≤θ≤37°, 37°≤θ≤39°, 39°≤θ≤41°, 41°≤θ≤43°, 43°≤θ≤45°, 45°≤θ≤47°, 47°≤θ≤49°, 49°≤θ≤51°, 51°≤θ≤53° or 53°≤θ≤55°. Illustratively, θ=25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54° or 55°, etc.

[0207] Such a setting can make the indoor unit 100 have a wide air supply range, which is conducive to covering various locations in the room, thereby achieving a more uniform indoor temperature distribution, improving the cooling effect, and avoiding the cold air from being directly concentrated on a certain position of the air guide plate 30 or a certain air guide plate 30, so as to reduce the generation of condensation.

[0208] Please also refer to Figure 7In some embodiments, the first air outlet 12 is formed with a first water receiving platform 14 in the height direction f3 of the casing 10, and the first water receiving platform 14 is rotatably connected to the bottom end of the air guide plate 30 in the height direction f3 of the casing 10; and the air guide plate 30 is provided with a water guide portion 31 on the surface in the thickness direction thereof, and the water guide portion 31 is located above the water receiving platform in the height direction f3 of the casing 10, and the water guide portion 31 is used to guide the condensed water on the air guide plate 30 to the first water receiving platform 14.

[0209] With such an arrangement, during the operation of the indoor unit 100, the condensed water generated on the air guide plate 30 can be promptly and quickly guided to the first water receiving platform 14 through the water guide part 31, thereby reducing the probability that the condensed water is directly carried out of the indoor unit 100 by the cold air blown out from the first air outlet 12, and flows to the ground or blows towards the user, thereby improving the user experience.

[0210] Optionally, the number of the water guide portion 31 provided on the air guide plate 30 may be one or more.

[0211] When there is only one water guide 31 provided on the air guide plate 30, the water guide 31 can be positioned near the first water receiving platform 14 so that the water guide 31 can accurately guide the condensed water into the first water receiving platform 14. When there are multiple water guides 31 provided on the air guide plate 30, the multiple water guides 31 are arranged at intervals along the height direction f3 of the housing 10.

[0212] In some embodiments, the water guide portion 31 can be set on one of the surfaces of the wind guide plate 30 along its thickness direction, or the water guide portion 31 can be set on both surfaces of the wind guide plate 30 along its thickness direction. This application does not limit this.

[0213] When the water guide portion 31 is provided on both surfaces of the air guide plate 30 along its thickness direction, the condensed water is guided to the first water receiving platform 14 more effectively than when the water guide portion 31 is provided on only one surface of the air guide plate 30 along its thickness direction.

[0214] Optionally, the water guide portion 31 in the present application can be a long strip convex rib structure protruding from the wind guide plate 30, and the extension direction of the long strip convex rib structure is set at an angle to the first direction f4, and is set in an inclined state to facilitate guiding the condensed water into the first water receiving platform 14.

[0215] Please refer again Figure 7In some embodiments, the indoor unit 100 includes a water receiving tray 50, which is disposed in the inner cavity 11 and is located below the first water receiving platform 14 in the height direction f3 of the casing 10 to receive condensed water on the first water receiving platform 14, thereby preventing the condensed water on the first water receiving platform 14 from overflowing and flowing to the ground, thereby further improving the user experience.

[0216] Please refer again Figure 8 and Figure 9 In order to facilitate the guidance of condensed water on the first water receiving platform 14 to the water receiving tray 50, in some embodiments, a first overflow hole 1111 is provided on the inner wall 111 near the first water receiving platform 14. In the height direction f3 of the housing 10, the first overflow hole 1111 is at least partially higher than the first water receiving platform 14, so that the first overflow hole 1111 can be used to guide the condensed water on the first water receiving platform 14 to the water receiving tray 50, thereby preventing the condensed water on the first water receiving platform 14 from overflowing and flowing to the ground, further improving the user experience.

[0217] In other embodiments, the first water receiving platform 14 is provided with a second overflow hole 141, which is used to guide the condensed water on the first water receiving platform 14 to the water receiving tray 50 to prevent the condensed water on the first water receiving platform 14 from overflowing and flowing to the ground, further improving the user experience.

[0218] In some other embodiments, a first overflow hole 1111 is provided on the inner wall 111 near the first water receiving platform 14. In the height direction f3 of the casing 10, the first overflow hole 1111 is at least partially higher than the first water receiving platform 14. At the same time, the first water receiving platform 14 is provided with a second overflow hole 141, so that the condensed water of the first water receiving platform 14 can flow to the water receiving tray 50 through the first overflow hole 1111 and the second overflow hole 141, so as to avoid the condensed water on the first water receiving platform 14 overflowing and flowing to the ground, thereby further improving the user experience.

[0219] See also Figure 9 When the inner side wall 111 is provided with a first overflow hole 1111, the first overflow hole 1111 includes a first hole wall surface 1111a and a second hole wall surface 1111b opposite to each other in the height direction f3 of the casing 10, wherein the first hole wall surface 1111a is located above the second hole wall surface 1111b in the height direction f3; and in the height direction f3 of the casing 10, the first hole wall surface 1111a is higher than the first water receiving platform 14, and the second hole wall surface 1111b is lower than or flush with the first water receiving platform 14.

[0220] Such a setting can not only ensure that the condensed water on the first water receiving platform 14 can flow from the first overflow hole 1111 to the water receiving tray 50, but also ensure that the condensed water on the first water receiving platform 14 can flow out from the first overflow hole 1111 without accumulating to a certain depth. In this way, the condensed water on the first water receiving platform 14 can flow from the first water receiving platform 14 into the first overflow hole 1111 in time, and then flow to the water receiving tray 50, thereby preventing the condensed water on the first water receiving platform 14 from overflowing and flowing to the ground, further improving the user experience.

[0221] It is understandable that the condensed water on the air guide plate 30 will flow downward along the air guide plate 30 in the height direction f3 of the casing 10 under the action of gravity. However, since the length of the air guide plate 30 in the height direction f3 of the casing 10 is usually relatively long, there may be a situation where the air guide plate 30 does not flow to the first water receiving platform 14, and is directly carried out of the indoor unit 100 by the cold air blown out from the first air outlet 12, and flows to the ground or blows towards the user.

[0222] See also Figure 10 and Figure 11 To this end, in some embodiments, the casing 10 is provided with a second water receiving platform 15 located at the first air outlet 12, and the second water receiving platform 15 extends along the width direction f2 of the casing 10, and the second water receiving platform 15 is rotatably connected to the air guide plate 30, and the second water receiving platform 15 is located between the water guide portion 31 and the first water receiving platform 14, and the water guide portion 31 is used to guide the condensed water on the air guide plate 30 to the second water receiving platform 15.

[0223] Such a setting can shorten the flow distance of the condensed water on the air guide plate 30, and quickly and timely guide the condensed water on the air guide plate 30 to the second water receiving platform 15, which can more effectively prevent the condensed water on the air guide plate 30 from being directly carried out of the indoor unit 100 by the cold air blown out from the first air outlet 12, flowing to the ground or blowing towards the user, thereby improving the user experience.

[0224] For example, the second water receiving platform 15 can be connected to the middle of the air guide plate 30 in the height direction f3 of the casing 10, thereby reinforcing the middle position of the air guide plate 30 along the height direction f3 of the casing 10, further improving the rotation stability of the air guide plate 30.

[0225] In some embodiments, a third overflow hole 1112 is provided on the inner wall 111 near the second water receiving platform 15. In the height direction f3 of the casing 10, the third overflow hole 1112 is at least partially higher than the second water receiving platform 15, so that the third overflow hole 1112 can be used to guide the condensed water on the second water receiving platform 15 to the water receiving tray 50, so as to avoid the condensed water on the second water receiving platform 15 overflowing and flowing to the ground, thereby further improving the user experience.

[0226] In other embodiments, the second water receiving platform 15 is provided with a fourth overflow hole 151, which is used to guide the condensed water on the second water receiving platform 15 to the water receiving tray 50 to prevent the condensed water on the second water receiving platform 15 from overflowing and flowing to the ground, further improving the user experience.

[0227] In some other embodiments, a third overflow hole 1112 is provided on the inner wall 111 near the second water receiving platform 15. In the height direction f3 of the casing 10, the third overflow hole 1112 is at least partially higher than the second water receiving platform 15. At the same time, the second water receiving platform 15 is provided with a fourth overflow hole 151, so that the condensed water of the second water receiving platform 15 can flow to the water receiving tray 50 through the third overflow hole 1112 and the fourth overflow hole 151, so as to avoid the condensed water on the second water receiving platform 15 overflowing and flowing to the ground, thereby further improving the user experience.

[0228] See also Figure 11 When the inner side wall 111 is provided with a third overflow hole 1112, the third overflow hole 1112 includes a third hole wall surface 1112a and a fourth hole wall surface 1112b that are opposite to each other in the height direction f3 of the casing 10, wherein the third hole wall surface 1112a is located above the fourth hole wall surface 1112b in the height direction f3; and in the height direction f3 of the casing 10, the third hole wall surface 1112a is higher than the second water receiving platform 15, and the fourth hole wall surface 1112b is lower than or flush with the second water receiving platform 15.

[0229] Such a setting can not only ensure that the condensed water on the second water receiving platform 15 can flow from the third overflow hole 1112 to the water receiving tray 50, but also ensure that the condensed water on the second water receiving platform 15 can flow out from the third overflow hole 1112 without accumulating to a certain depth. In this way, the condensed water on the second water receiving platform 15 can flow from the second water receiving platform 15 into the third overflow hole 1112 in a timely manner, and then flow to the water receiving tray 50, thereby avoiding the condensed water on the second water receiving platform 15 from overflowing and flowing to the ground, further improving the user experience.
