[0050] In order to make the purpose, technical solutions and advantages of this application clearer, the following part will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0051] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0052] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, in the description of this application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0054] In the related art, when the indoor unit of the HVAC system is in use, the air sent out from the air outlet of the indoor unit will pass through the air outlet of the panel structure and then flow out. However, when the indoor unit is in the cooling state, the cold air sent out from the air outlet of the indoor unit will transfer the cold energy to the panel structure when flowing through the air outlet, causing condensation on the outer surface of the panel structure.

[0055] In order to solve the above problems, the present application proposes a HVAC equipment. In the embodiment of the present application, the HVAC equipment includes but is not limited to air conditioners, multi-split units, heat pumps and other equipment, and can be used in large-scale places such as shopping malls and office buildings. Among them, the HVAC system may include an indoor unit, an outdoor unit (not shown in the figure) and a connecting pipe (not shown in the figure). The indoor unit is connected to the outdoor unit through the connecting pipe so that the indoor unit and the outdoor unit form a refrigerant circulation. In some actual use scenarios, the indoor unit of the present application can be installed indoors, the outdoor unit is responsible for cooling or heating, and transports the refrigerant through the connecting pipe. The refrigerant exchanges heat with the indoor air and the outdoor air respectively, and the indoor unit is responsible for transporting cold air or hot air to the room to achieve the effect of cooling or heating.

[0056] Please refer to Figure 1. Specifically, the indoor unit may include a ceiling unit, a duct unit or a wall-mounted air-conditioning indoor unit, etc. Among them, the ceiling unit is usually embedded in the ceiling in the form of a suspended ceiling, so as to hide the ceiling unit through the ceiling. In this way, the ceiling unit has a better hiding effect and is more beautiful than other indoor units.

[0057] Please refer to FIG. 1 and FIG. 2 . In some embodiments, the indoor unit 100 may include a body 10 and a panel structure 30 . The panel structure 30 is connected to the body 10 .

[0058] The housing 10 is provided with a return air vent (not shown) and a supply air vent 11a. An air duct is formed within the housing 10, communicating with the return air vent and the supply air vent 11a, respectively. The air duct includes a heat exchange chamber and a fan chamber. Airflow from the return air vent flows sequentially through the heat exchange chamber and the fan chamber before being delivered through the supply air vent 11a to the panel structure 30. Finally, it flows outward from the panel structure 30, thereby fulfilling the air supply function of the indoor unit 100.

[0059] The panel structure 30 includes a panel body 31 and a first insulation member 33 connected to the panel body 31. The panel body 31 serves as the main structure of the panel structure 30 and has a rectangular or square shape. The panel body 31 can be made of plastic, which provides advantages such as light weight and an aesthetically pleasing appearance. Of course, the panel body 31 can also be made of metal, which provides advantages such as higher strength and better corrosion resistance. This application does not impose any restrictions on this.

[0060] The first thermal insulation member 33 may be in the form of a foam member, wherein the foam member has a low thermal conductivity coefficient of approximately 0.03 W / (m·K). Of course, the first thermal insulation member 33 may also be in the form of a flocked plastic member or sponge, or other member having a low thermal conductivity coefficient, which is not limited in this application. The first thermal insulation member 33 is connected to the panel body 31.

[0061] Referring to Figure 2 , to improve the positional accuracy of the first thermal insulation member 33 when connected to the panel body 31, a limit member 3137 is provided on the upper surface of the panel body 31, and a limit groove 337 is provided on the first thermal insulation member 33 to engage with the limit member 3137. In this way, the first thermal insulation member 33 and the panel body 31 can be pre-fixed by the limit member 3137 and the limit groove 337. After the pre-fixed first thermal insulation member 33 and the panel body 31, the first thermal insulation member 33 and the panel body 31 can be fixedly connected. This improves the positional accuracy of the first thermal insulation member 33 when connected to the panel body 31, facilitating installation.

[0062] Please refer to Figures 1 and 2 in combination, in which the panel structure 30 is formed with an air outlet channel 311 connected to the air supply port 11a. It is understandable that the airflow flowing out through the air supply port 11a will flow into the room through the air outlet channel 311, and under the cooling function of the indoor unit 100, this part of the airflow will have cooling capacity. If the airflow flows through the panel body 31, the cooling capacity of the airflow will be transferred to the panel body 31, resulting in a temperature difference between the inside and outside of the panel body 31, and then causing condensation on the lower surface of the panel body 31 (that is, the exterior surface of the panel body 31). Based on this, the first thermal insulation component 33 of the embodiment of the present application is configured to form at least a portion of the inner wall surface of the air outlet channel 311.

[0063] In some structural forms, the first thermal insulation member 33 may form the air outlet channel 311 alone. Specifically, a relief opening may be provided on the panel body 31, and the bottom of the first thermal insulation member 33 may be provided within the relief opening. In this way, the first thermal insulation member 33 may be configured to form all inner wall surfaces of the air outlet channel 311. As the air flows through the air outlet channel 311, the cooling energy of the airflow is blocked by the first thermal insulation member 33, thereby preventing the cooling energy of the airflow from being transferred to the panel body 31. In other structural forms, the first thermal insulation member 33 may form a portion of the inner wall surfaces of the air outlet channel 311, and the panel body 31 may form the remaining wall surfaces of the air outlet channel 311. In this way, the cooling energy of the airflow flowing within the air outlet channel 311 and flowing toward the position where the first thermal insulation member 33 is provided on the panel body 31 can be blocked by the first thermal insulation member 33, thereby preventing the cooling energy of the airflow from being transferred to the position where the first thermal insulation member 33 is provided on the panel body 31.

[0064] In summary, by providing the first thermal insulation member 33 and configuring the first thermal insulation member 33 to form at least a portion of the inner wall surface of the air outlet channel 311, the panel structure 30 of the embodiment of the present application has at least the following technical effects:

[0065] When the indoor unit 100 turns on the cooling function, the air flow flowing out from the air outlet 11a of the body 10 can effectively isolate at least part of the cold air flow when flowing through the air outlet channel 311 due to the low thermal conductivity of the first thermal insulation component 33, so as to prevent the air flow from flowing to the panel body 31 and exchanging heat with the panel body 31. Therefore, the cold air flow can be prevented from being transferred to the panel body 31 and causing a temperature difference between the inside and outside of the panel body 31, thereby effectively reducing the possibility of condensation on the panel body 31, and further preventing condensation water from dripping into the room to cause indoor humidity, and preventing the wall or decorative materials from becoming moldy.

[0066] Please refer to Figures 1 and 2. In some embodiments, the body 10 includes a housing 11, a water receiving tray 13, a heat exchanger (not shown), and a second thermal insulation member 17. The housing 11 can be rectangular and define the overall outline of the body 10. The housing 11 can be made of plastic to provide advantages such as light weight, beautiful appearance, and resistance to cracking. Of course, the housing 11 can also be made of metal to provide advantages such as high strength and excellent corrosion resistance, which is not limited in this application. The above-mentioned air duct is formed in the housing 11.

[0067] The water receiving tray 13 can be made of plastic material so that the casing 11 has advantages such as light weight. The water receiving tray 13 is located inside the casing 11. Specifically, the water receiving tray 13 defines part of the cavity wall of the heat exchange cavity and is fixedly connected to the inner side of the body 10.

[0068] The heat exchanger can be in a variety of shapes, including linear, V-shaped, curved, or wavy. The heat exchanger is housed within the housing 10, specifically within the heat exchange chamber. The heat exchanger is positioned above the water tray 13, allowing the tray 13 to receive condensed water flowing out of the heat exchanger.

[0069] The second thermal insulation member 17 can be in the form of a foam member, wherein the foam member has a low thermal conductivity coefficient, and its thermal conductivity coefficient is about 0.03W / (m·K). Of course, the second thermal insulation member 17 can also be in the form of flocked plastic members or sponges and other forms with low thermal conductivity coefficients, and this application does not limit this. The second thermal insulation member 17 is connected to the surface of the water receiving tray 13 away from the heat exchanger. For example, the second thermal insulation member 17 can be fixed to the water receiving tray 13 by bonding or other means, thereby achieving a more stable connection effect. In this way, the second thermal insulation member 17 can prevent the coldness of the condensed water on the water receiving tray 13 from being transferred to the panel body 31, and can reduce heat loss in the air duct to improve the operating efficiency of the body 10.

[0070] Among them, the first thermal insulation component 33 and the second thermal insulation component 17 cooperate to define an insulation space 50, and the insulation space 50 is filled with gas or insulation material. It is understandable that gas has good thermal insulation properties, and the insulation material can be a material with a low thermal conductivity coefficient such as a foam component, a flocked plastic component or a sponge. Whether gas or insulation material is filled in the insulation space 50, it can perform a composite insulation function with the first thermal insulation component 33 and the second thermal insulation component 17, so that the cold air flow can be more effectively blocked, thereby greatly reducing the possibility of the cold air flow being transferred to the panel body 31. It is understandable that the form of filling the insulation space 50 with gas can reduce the amount of insulation material used compared to the form of filling the insulation space 50 with insulation material, thereby reducing the overall production cost of the indoor unit 100.

[0071] Referring to Figure 2 , the heat-insulating space 50 further comprises a first space 51 and a second space 53 that are interconnected. The first space 51 extends horizontally, and the second space 53 extends vertically. It is understood that one open end of the second space 53 is connected to the first space 51, while the other open end is located closer to the panel body 31. In other words, the second space 53 is located closer to the panel body 31 than the first space 51.

[0072] Based on this, the insulation effect required of the second space 53 must be greater than that of the first space 51. Therefore, in the embodiment of the present application, the volume of the second space 53 is set to be greater than that of the first space 51, so that the volume of the gas filling the second space 53 can be greater than the volume of the gas filling the first space 51, or the volume of the insulation material filling the second space 53 can be greater than the volume of the insulation material filling the first space 51. This increases the volume of the gas or insulation material filling the second space 53, thereby achieving a better insulation effect while maintaining the vertical cross-sectional area of ​​the first space 51 and thus maintaining the vertical size of the indoor unit 100. Of course, in other embodiments, the volume of the second space 53 can also be equivalent to that of the first space 51, and this is not limited in this application.

[0073] On the basis that one open end of the second space 53 is connected to the first space 51, and the other open end is located near the panel body 31, please continue to refer to Figure 2, and the cross-sectional area of ​​the second space 53 along the horizontal direction is set to have a tendency to gradually increase in the vertical direction and in the direction from the water receiving tray 13 toward the panel body 31. In this way, the cross-sectional area of ​​the second space 53 closer to the panel body 31 will be larger, so that more gas or insulation material can be filled, thereby having a better effect of blocking the cold air of the panel body 31. Of course, in other embodiments, the cross-sectional area of ​​the second space 53 along the horizontal direction can also be equal everywhere in the vertical direction and in the direction from the water receiving tray 13 toward the panel body 31, and this application does not limit this.

[0074] In order to achieve a trend of gradually increasing the cross-sectional area of ​​the second space 53 along the horizontal direction in the vertical direction and in the direction from the water receiving tray 13 toward the panel body 31, please continue to refer to Figure 2. In some structural forms, in the vertical direction and in the direction from the water receiving tray 13 toward the panel body 31, the surface of the second thermal insulation member 17 that defines the second space 53 is tilted in the direction away from the first thermal insulation member 33. In this way, while ensuring that the shape of the first thermal insulation member 33 remains unchanged to ensure the cold blocking effect of the first thermal insulation member 33, the cross-sectional area of ​​the second space 53 along the horizontal direction can have a trend of gradually increasing. Of course, in other embodiments, the surface of the first thermal insulation member 33 that defines the second space 53 can also be tilted in the vertical direction and in the direction from the water receiving tray 13 toward the panel body 31, and this application is not limited to this.

[0075] Referring to Figures 2 and 3 , in some embodiments, the panel body 31 includes a bottom plate 3131 and a surrounding plate 3133 connected to the bottom plate 3131. The first thermal insulation member 33 abuts the bottom plate 3131 and, at least in conjunction with the surrounding plate 3133, forms an air outlet passage 311. Thus, when air flows from the air supply port 11a toward the air outlet passage 311, the first thermal insulation member 33 blocks the cooling energy of the airflow, preventing the cooling energy from being transferred to the point where the surrounding plate on the panel body 31 contacts the bottom of the first thermal insulation member 33.

[0076] Please refer to Figures 1 to 3 . Furthermore, the panel body 31 includes a base plate 313 and a skirt 315. The base plate 313 is connected to the body 10 and includes a bottom plate 3131 and a skirt 315. The skirt 315 is disposed around the periphery of the base plate 313. It is understood that the base plate 313, as the main structure of the panel body 31, plays a major role in the appearance of the panel body 31. The skirt 315 disposed around the periphery of the base plate 313 can provide a certain shielding effect on the body 10, thereby enhancing the decorative effect of the panel structure 30. In addition, the skirt 315 can also provide a certain strength to the entire panel body 31, thereby enhancing the overall strength of the panel body 31.

[0077] Based on this, the first thermal insulation component 33 cooperates with at least the enclosure 3133 of the substrate 313 to form an air outlet channel 311, so that the first thermal insulation component 33 can block the cold air flow from being transferred to the lower surface of the substrate 313 (that is, the appearance surface of the substrate 313), thereby reducing the possibility of condensation on the substrate 313.

[0078] Please refer to FIG. 3 . In some structural forms, the first heat-insulating member 33 , the surrounding plate 3133 , and the bottom plate 3131 cooperate to form an air outlet channel 311 , and the bottom plate 3131 defines an air outlet 312 of the air outlet channel 311 .

[0079] The bottom of the first thermal insulation component 33 contacts the bottom plate 3131, and part of the structure of the first thermal insulation component 33 extends into the area above the air outlet 312. In the vertical direction, part of the structure of the first thermal insulation component 33 can be exposed by the air outlet 312. In this way, when the airflow flows through the air outlet channel 311, it will be partially blocked by the first thermal insulation component 33 extending into the area above the air outlet 312, and then flow into the room. This can prevent the airflow from contacting the bottom plate 3131 and generating heat exchange. Of course, in other structural forms, the first thermal insulation component 33 may not be exposed by the air outlet 312 in the vertical direction, and this embodiment of the application is not limited to this.

[0080] Referring to Figure 2 , in some embodiments, at least a portion of the inner wall of the air outlet channel 311 formed by the first thermal insulation member 33 is formed with a guide surface 331. The air outlet channel 311 has an air outlet 312, and the air outlet 312 has a centerline. The guide surface 331 is configured to guide the airflow passing through the air outlet channel 311 to a position near the centerline of the air outlet 312.

[0081] In this way, under the guidance of the guide surface 331, the airflow flowing through the air outlet channel 311 can be guided to a position as far away from the panel body 31 as possible, reducing the possibility of condensation caused by excessive cold transfer between the panel body 31 and the airflow.

[0082] In addition, based on the arrangement in which part of the structure of the first thermal insulation component 33 extends into the upper area of ​​the air outlet 312 and part of the structure of the first thermal insulation component 33 can be exposed by the air outlet 312 in the vertical direction, the airflow can first be guided by the guide surface 331, and then guided by the part of the structure of the first thermal insulation component 33 extending into the upper area of ​​the air outlet 312. Finally, the airflow will flow to a position close to the center line of the air outlet 312, which can better avoid the transfer of cold air between the airflow and the panel body 31.

[0083] The panel structure 30 further includes an air deflector (not shown), which is movably connected to the panel body 31 and disposed at the air outlet passage 311. It will be appreciated that, based on the movably connected air deflector to the panel body 31, the air deflector can swing to guide the airflow flowing through the air outlet passage 311 to different areas within the room.

[0084] Based on the setting of the guide surface 331, during the operation of the air guide plate, the guide surface 331 can guide part of the airflow to the back of the air guide plate, so that airflow can flow through both the front and back of the air guide plate, thereby avoiding the temperature difference between the front and back of the air guide plate and the occurrence of condensation.

[0085] 1 and 2 , in some embodiments, the housing 10 includes a fan 15 housed within a fan cavity. Airflow passing through the heat exchange cavity into the fan cavity is driven by the fan 15 and is then flung toward the air outlet 311 .

[0086] The air outlet channel 311 extends in the axial direction of the wind rotor 15. The first thermal insulation member 33 is formed as at least an inner wall surface of the air outlet channel 311 extending in the axial direction of the wind rotor 15. That is, the first thermal insulation member 33 may be formed as an inner wall surface of the air outlet channel 311 extending in the axial direction of the wind rotor 15, or the first thermal insulation member 33 may be formed not only as an inner wall surface of the air outlet channel 311 extending in the axial direction of the wind rotor 15, but also as an inner wall surface of the air outlet channel 311 extending perpendicular to the axis of the wind rotor 15. This application does not impose any limitation on this.

[0087] It can be understood that the direction of the airflow thrown out by the wind wheel 15 will be roughly tangent to the cross-section of the blades of the wind wheel 15. In this way, the airflow flow rate flowing into the inner wall surface extending axially of the wind wheel 15 in the air outlet channel 311 will be relatively large. Based on this, by setting the first thermal insulation component 33 to form the inner wall surface extending axially of the wind wheel 15 in the air outlet channel 311, the coldness of this part of the airflow with a larger flow rate can be better blocked from being transferred to the panel body 31.

[0088] 2 and 3 , in some embodiments, the panel structure 30 further includes a reinforcement member 35. The reinforcement member 35 may be in the form of an elongated strip and may be a sheet metal member to provide advantages such as better strength. Alternatively, the reinforcement member 35 may be a plastic member, and better strength may be achieved by increasing the thickness of the reinforcement member 35.

[0089] The reinforcement 35 is connected to the side of the first thermal insulation component 33 away from the panel body 31. In this way, the reinforcement 35 is connected to the bottom plate 3131 of the panel body 31 through the first thermal insulation component 33, thereby improving the strength of the panel structure 30, especially improving the strength of the part of the bottom plate 3131 that constructs the air outlet channel 311, and avoiding the situation where the part of the bottom plate 3131 that constructs the air outlet channel 311 bends and deforms downward due to poor strength.

[0090] Referring to Figures 3 to 6 , a stepped groove 333 is further formed on the side of the first thermal insulation member 33 facing away from the bottom plate 3131 of the panel body 31. The reinforcement member 35 is disposed in the stepped groove 333 and includes a first reinforcement portion 351 and a second reinforcement portion 353. The second reinforcement portion 353 is connected to the first reinforcement portion 351 and forms an angle with the first reinforcement portion 351. It is understood that the first reinforcement portion 351 and the second reinforcement portion 353 can be connected to form an L-shape.

[0091] The first reinforcing portion 351 is disposed against the sidewalls of the stepped groove 333, and the second reinforcing portion 353 is disposed against the bottom wall of the stepped groove 333. Thus, the first reinforcing portion 351 and the second reinforcing portion 353 cooperate to enhance the reinforcing effect of the reinforcing member 35 on the panel body 31.

[0092] Referring to Figures 2 and 3 , in some configurations, a threaded post 3135 protrudes from the upper surface of the panel body 31, and both the reinforcement member 35 and the first thermal insulation member 33 are provided with escape holes corresponding to the threaded post 3135. A threaded fastener 37 passes through the escape holes of the reinforcement member 35, the escape holes of the first thermal insulation member 33, and the threaded post 3135 to secure the reinforcement member 35, the first thermal insulation member 33, and the panel body 31. This threaded connection enhances the connection strength between the reinforcement member 35 and the panel body 31, thereby further strengthening the reinforcement member 35's effect on the bottom plate 3131 of the panel body 31. In addition, compared with the form in which a threaded hole is opened on the panel body 31, the form in which a threaded column 3135 is provided and the threaded column 3135 is protruded from the upper surface of the panel body 31, the threaded column 3135 can be blocked by the panel body 31, so that the user cannot directly observe the threaded column 3135 from the outside, thereby improving the overall aesthetics of the panel structure 30.

[0093] Referring to Figures 2 to 5 , in some embodiments, a snap-fit ​​groove 335 is formed on the side of the first thermal insulation member 33 facing the water receiving tray 13, and a snap-fit ​​portion 131 is provided on the side of the water receiving tray 13 near the air outlet channel 311. The snap-fit ​​portion 131 snaps into the snap-fit ​​groove 335 and cooperates with the panel body 31 to clamp the first thermal insulation member 33. In this way, the first thermal insulation member 33 can be sealed and sandwiched between the water receiving tray 13 and the bottom plate 3131 of the panel body 31, thereby preventing airflow from flowing from between the water receiving tray 13 and the bottom plate 3131 of the panel body 31 to the panel body 31, so that the first thermal insulation member 33 can effectively block the cooling effect of airflow. Furthermore, the clamping arrangement can improve the stability of the first thermal insulation member 33 between the water receiving tray 13 and the bottom plate 3131 of the panel body 31.

[0094] Referring to Figures 8 and 9 , in some other embodiments, the second thermal insulation member 17 is at least partially positioned above the first thermal insulation member 33. That is, the second thermal insulation member 17 and the first thermal insulation member 33 overlap to a certain extent. For example, only a portion (such as the portion near the edge of the air outlet channel 311) is positioned above the first thermal insulation member 33. Alternatively, the second thermal insulation member 17 may completely cover the corresponding portion of the first thermal insulation member 33.

[0095] The second thermal insulation component 17 cooperates with the first thermal insulation component 33 to form a guide surface 331 on at least part of the inner wall surface of the air outlet channel 311. The air outlet channel 311 has an air outlet 312 and the air outlet 312 has a center line. The guide surface 331 is configured to guide the airflow flowing through the air outlet channel 311 to a position close to the center line of the air outlet 312. In this way, under the guiding action of the guide surface 331, the airflow flowing through the air outlet channel 311 can be guided as far away from the panel body 31 as possible, reducing the possibility of condensation caused by excessive cold transfer between the panel body 31 and the airflow. Optionally, the guide surface 331 can be designed to be arc-shaped. By stacking and cooperating with the first thermal insulation component 33 and the second thermal insulation component 17 to form part of the inner wall surface of the air channel 311, it can not only effectively reduce the possibility of condensation, but also effectively increase the thickness of the inner wall surface, thereby ensuring its strength and preventing the deformation of the inner wall surface from affecting the airflow. In this embodiment, the inner wall formed by the first thermal insulation member 33 and the second thermal insulation member 17 effectively blocks the cold airflow from affecting the panel body 31. When the indoor unit 100 is operating, the airflow within the air outlet duct 311 is relatively low in temperature. If it directly contacts the panel body 31, it can easily cause the surface temperature of the panel body 31 to drop, leading to condensation and other problems. The first thermal insulation member 33 and the second thermal insulation member 17, acting as the inner wall of the air outlet duct 311, effectively block the flow of cold airflow to the panel body 31, thereby maintaining a stable temperature of the panel body 31.

[0096] 8 and 9 , in some embodiments, a limiting protrusion 338 is formed on one side of the first heat-insulating member 33 facing the second heat-insulating member 17. The limiting protrusion 338 can be designed in various shapes, such as a cuboid, a cylinder, or other regular or irregular three-dimensional shapes.

[0097] The second thermal insulation member 17 has a limiting recess 171 into which the limiting protrusion 338 extends. The limiting recess 171 is shaped to match the limiting protrusion 338. For example, if the limiting protrusion 338 is a rectangular parallelepiped, the limiting recess 171 is a corresponding rectangular parallelepiped groove to ensure that the limiting protrusion 338 can extend therein, thereby achieving a stable connection.

[0098] The limiting recess 171 cooperates with the panel body 31 to clamp the first thermal insulation member 33. The panel body 31 plays a supporting and clamping role. The panel body 31 and the limiting recess 171 cooperate together to fix the first thermal insulation member 33 between the second thermal insulation member 17 and the bottom plate 3131 of the panel body 31.

[0099] In this embodiment, the first thermal insulation component 33 can be sealed and clamped between the second thermal insulation component 17 and the bottom plate 3131 of the panel body 31, thereby forming a relatively sealed structure. During the operation of the indoor unit 100, the airflow can be prevented from flowing from the water receiving tray 13 to the panel body 31. Since the temperature of the airflow is relatively low when passing through the water receiving tray 13, if it flows directly to the panel body 31, the temperature of the panel body 31 will be reduced, and problems such as condensation water may be generated on the surface. In this embodiment, through the above-mentioned sealing structure, the first thermal insulation component 33 can effectively block the cold airflow, maintain the temperature of the panel body 31 stable, and improve the operating efficiency of the indoor unit 100 and the user experience.

[0100] At the same time, the cooperation between the limiting protrusion 338 and the limiting recess 171 and the clamping effect of the panel body 31 greatly improves the connection stability of the first heat insulation component 33.

[0101] 8 and 9 , in some embodiments, a second engaging groove 172 is formed on the side of the second heat-insulating member 17 facing the water receiving tray 13. The second engaging groove 172 can be in the shape of a dovetail groove, a T-shaped groove, or other engaging shapes.

[0102] A clamping portion 131 is provided on one side of the water receiving tray 13 close to the air outlet channel 311. The shape of the clamping portion 131 matches the second clamping groove 172. For example, when the second clamping groove 172 is a dovetail groove, the clamping portion 131 is a corresponding dovetail shape.

[0103] The clamping portion 131 is clamped on the second clamping groove 172 and cooperates with the first insulation member 33 to clamp the second insulation member 17. The clamping portion 131 of the water receiving tray 13 is at the top and the first insulation member 33 is at the bottom, together fixing the second insulation member 17 in the middle position.

[0104] In this embodiment, the second heat-insulating member 17 can be sealed and sandwiched between the water receiving tray 13 and the first heat-insulating member 33, forming a double sealing structure with the first heat-insulating member 33. The double sealing further effectively prevents airflow from flowing from the water receiving tray 13 toward the bottom plate 3131 of the panel body 31.

[0105] Through the clamping setting, the stability of the first thermal insulation component 33 and the second thermal insulation component 17 between the water receiving tray 13 and the bottom plate 3131 of the panel body 31 is greatly improved. During the operation of the indoor unit 100, regardless of being affected by vibration or other external forces, the first thermal insulation component 33 and the second thermal insulation component 17 can remain stable, effectively ensuring that the first thermal insulation component 33, the second thermal insulation component 17 and the clamping portion 131 can accurately form and maintain the arc-shaped guide surface 331, and effectively avoiding the displacement of the fitting between the first thermal insulation component 33, the second thermal insulation component 17 and the clamping portion 131 due to vibration or other external forces during the operation of the indoor unit 100, thereby causing a convex portion to appear on the guide surface 331, affecting the smoothness of the airflow or air leakage to the fitting between the first thermal insulation component 33, the second thermal insulation component 17 and the clamping portion 131.
