[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0045] When the following description refers to the 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 only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0046] In the description of the present 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 the present application can be understood according to the specific circumstances. In addition, in the description of the present 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 objects associated before and after are in an "or" relationship.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0048] In the related art, when the indoor unit of the HVAC system is in use, the air delivered 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 a cooling state, the cold air delivered 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 exterior surface of the panel structure.

[0049] To solve the above problems, the present application proposes a HVAC device. In the embodiment of the present application, the HVAC device 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), and the indoor unit is connected to the outdoor unit through a connecting pipe so that the indoor unit and the outdoor unit form a refrigerant cycle. 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 the refrigerant is transported 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.

[0050] See also Figure 1 Specifically, the indoor unit may include a ceiling unit, a duct unit or a wall-mounted air-conditioning indoor unit, among which 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.

[0051] Please refer to Figure 1 to Figure 2 In some embodiments, the indoor unit 100 may include a body 10 and a panel structure 30 , and the panel structure 30 is connected to the body 10 .

[0052] The body 10 is provided with a return air port (not shown in the figure) and an air supply port 11a, and an air duct connected to the return air port and the air supply port 11a is formed inside the body 10, and the air duct includes a heat exchange cavity and a fan cavity connected to each other. The airflow flowing in from the return air port flows to the heat exchange cavity and the fan cavity in turn, and then is sent to the panel structure 30 through the air supply port 11a, and finally flows out from the panel structure 30, thereby realizing the air supply function of the indoor unit 100.

[0053] The panel structure 30 includes a panel body 31 and a first heat-insulating member 33 connected to the panel body 31. The panel body 31 is the main structure of the panel structure 30 and is in a rectangular or square shape. The panel body 31 can be made of plastic material so that the panel body 31 has advantages such as light weight and beautiful appearance. Of course, the panel body 31 can also be made of metal material so as to have advantages such as high strength and good corrosion resistance. This application does not limit this.

[0054] The first heat-insulating member 33 may be in the form of a foam member, wherein the foam member has a relatively low thermal conductivity coefficient, and its thermal conductivity coefficient is about 0.03W / (m·K). Of course, the first heat-insulating member 33 may also be in the form of a flocked plastic member or sponge or other forms with relatively low thermal conductivity coefficient, and the present application does not limit this. The first heat-insulating member 33 is connected to the panel body 31.

[0055] See also Figure 2 In order to improve the position accuracy of the first thermal insulation component 33 connected to the panel body 31, a limiter 3137 is provided on the upper surface of the panel body 31, and the first thermal insulation component 33 is provided with a limiter groove 337 that cooperates with the limiter 3137. In this way, the first thermal insulation component 33 and the panel body 31 can be pre-fixed by the limiter 3137 and the limiter groove 337, and then after the first thermal insulation component 33 and the panel body 31 are pre-fixed, the first thermal insulation component 33 and the panel body 31 are fixedly connected, so that the position accuracy of the first thermal insulation component 33 connected to the panel body 31 can be improved, and installation is convenient.

[0056] Please refer to Figure 1 to Figure 2 , wherein 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 coldness. If the airflow flows through the panel body 31, the coldness 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 appearance 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 part of the inner wall surface of the air outlet channel 311.

[0057] In some structural forms, the air outlet channel 311 can be formed by the first thermal insulation component 33 alone. Specifically, a avoidance opening is provided on the panel body 31, and the bottom of the first thermal insulation component 33 is provided in the avoidance opening. In this way, the first thermal insulation component 33 can be configured to form all the inner wall surfaces of the air outlet channel 311, so that when the airflow flows through the air outlet channel 311, the cold airflow will be blocked by the first thermal insulation component 33, thereby preventing the cold airflow from being transferred to the panel body 31. In other structural forms, a part of the inner wall surface of the air outlet channel 311 can be formed by the first thermal insulation component 33, and the remaining other wall surfaces of the air outlet channel 311 can be formed by the panel body 31. In this way, the cold airflow flowing in the air outlet channel 311 and flowing to the position where the first thermal insulation component 33 is provided on the panel body 31 can be blocked by the first thermal insulation component 33, thereby preventing the cold airflow from being transferred to the position where the first thermal insulation component 33 is provided on the panel body 31.

[0058] In summary, by providing the first heat-insulating member 33, and the first heat-insulating member 33 being configured 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:

[0059] When the indoor unit 100 turns on the cooling function, when the air flow flowing out from the air supply port 11a of the body 10 flows through the air outlet channel 311, due to the low thermal conductivity of the first thermal insulation component 33, at least part of the cold air flow can be effectively isolated 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, thereby preventing condensation water from dripping into the room to cause indoor humidity, and preventing the wall or decorative materials from getting moldy.

[0060] Please refer to Figure 1 to Figure 2 In some embodiments, the machine body 10 includes a housing 11, a water tray 13, a heat exchanger (not shown), and a second heat-insulating member 17. The housing 11 may be rectangular and define the overall outline of the machine body 10. The housing 11 may be made of plastic so that the housing 11 has the advantages of being light, beautiful in appearance, and not prone to cracking. Of course, the housing 11 may also be made of metal so that it has the advantages of being high in strength and having good corrosion resistance, which is not limited in this application. The above-mentioned air duct is formed in the housing 11.

[0061] 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.

[0062] The heat exchanger can be in a variety of shapes such as linear, V-shaped, arc-shaped or wavy. The heat exchanger is accommodated inside the body 10, that is, accommodated in the heat exchange cavity. The heat exchanger is located above the water receiving tray 13 so that the water receiving tray 13 can receive the condensed water flowing out of the heat exchanger.

[0063] The second thermal insulation member 17 can be in the form of a foam member, wherein the foam member has a low thermal conductivity, and its thermal conductivity is about 0.03W / (m·K). Of course, the second thermal insulation member 17 can also be in the form of flocked plastic or sponge and other forms with low thermal conductivity, and the present application does not limit this. The second thermal insulation member 17 is connected to the surface of the water receiving pan 13 away from the heat exchanger. For example, the second thermal insulation member 17 can be fixed to the water receiving pan 13 by bonding or the like, which has a more stable connection effect. In this way, the second thermal insulation member 17 can prevent the cold of the condensed water on the water receiving pan 13 from being transferred to the panel body 31, and can reduce the heat loss in the air duct to improve the operating efficiency of the body 10.

[0064] Among them, the first thermal insulation component 33 and the second thermal insulation component 17 cooperate to define the thermal insulation space 50, and the thermal insulation space 50 is filled with gas or thermal insulation material. It can be understood that the gas has good thermal insulation performance, and the thermal insulation material can be a foam component, a flocked plastic component or a sponge and other materials with a low thermal conductivity. Whether the gas or the thermal insulation material is filled in the thermal insulation space 50, it can perform a composite thermal insulation function with the first thermal insulation component 33 and the second thermal insulation component 17, so that the cold of the airflow can be more effectively blocked, so as to greatly reduce the possibility of the cold of the airflow being transferred to the panel body 31. It can be understood that the form of filling the thermal insulation space 50 with gas can reduce the amount of thermal insulation material used compared to the form of filling the thermal insulation space 50 with thermal insulation material, thereby playing the effect of reducing the overall production cost of the indoor unit 100.

[0065] See also Figure 2 Further, the heat preservation space 50 includes a first space 51 and a second space 53 which are connected to each other. The first space 51 extends in the horizontal direction, and the second space 53 extends in the vertical direction. It can be understood that one opening end of the second space 53 is connected to the first space 51, and the other opening end is arranged close to the panel body 31, that is, the second space 53 is arranged closer to the panel body 31 than the first space 51.

[0066] Based on this, the insulation effect required by the second space 53 is greater than that of the first space 51, so the volume of the second space 53 is set to be greater than that of the first space 51 in the embodiment of the present application, so that the volume of the gas filled in the second space 53 can be greater than the volume of the gas filled in the first space 51, or the volume of the insulation material filled in the second space 53 can be greater than the volume of the insulation material filled in the first space 51, so that the volume of the gas or insulation material filled in the second space 53 is larger, which can not only achieve a better insulation effect, but also can not increase the longitudinal cross-sectional area of ​​the first space 51 in the vertical direction, thereby not increasing the size of the indoor unit 100 in the vertical direction. Of course, in other embodiments, the volume of the second space 53 can also be equivalent to the volume of the first space 51, and the present application does not limit this.

[0067] On the basis that one opening end of the second space 53 is connected to the first space 51 and the other opening end is disposed close to the panel body 31, please continue to refer to Figure 2 , 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 to 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 thermal insulation materials can be filled, which has a better effect of blocking coldness for 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 to the panel body 31, and the present application does not limit this.

[0068] In order to realize that the cross-sectional area of ​​the second space 53 along the horizontal direction has a tendency to gradually increase 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 to the panel body 31, the surface of the second heat-insulating member 17 that forms the second space 53 is tilted in the direction away from the first heat-insulating member 33. In this way, while ensuring that the shape of the first heat-insulating member 33 remains unchanged to ensure the cold-blocking effect of the first heat-insulating member 33, the cross-sectional area of ​​the second space 53 along the horizontal direction can have a tendency to gradually increase. Of course, in other embodiments, the surface of the first heat-insulating member 33 that forms the second space 53 can also be tilted in the direction away from the second heat-insulating member 17 in the vertical direction and in the direction from the water receiving tray 13 to the panel body 31, and the present application does not limit this.

[0069] Please refer to Figures 2 to 3In 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 against the bottom plate 3131 and at least cooperates with the surrounding plate 3133 to form an air outlet channel 311. In this way, when the airflow flows from the air supply port 11a to the air outlet channel 311, the first thermal insulation member 33 can block the coldness of the airflow, and prevent the coldness of the airflow from being transferred to the position where the surrounding plate on the panel body 31 contacts the bottom of the first thermal insulation member 33.

[0070] Please refer to Figures 1 to 3 Further, 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 arranged around the periphery of the base plate 313. It can be 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, and the skirt 315 arranged around the periphery of the base plate 313 can have a certain shielding effect on the body 10, so that the decorative effect of the panel structure 30 is better, and the skirt 315 can have a certain strength-increasing effect on the whole of the panel body 31, so that the overall strength of the panel body 31 is better.

[0071] Based on this, by cooperating with the first thermal insulation component 33 at least together with the enclosure 3133 of the substrate 313 to form the air outlet channel 311, 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.

[0072] See also Figure 3 In some structural forms, the first thermal insulation component 33 , the enclosure 3133 , and the bottom plate 3131 cooperate to construct the air outlet channel 311 , and the bottom plate 3131 defines the air outlet 312 of the air outlet channel 311 .

[0073] The bottom of the first thermal insulation component 33 is in contact with the bottom plate 3131, and part of the structure of the first thermal insulation component 33 extends into the upper area of ​​the air outlet 312, and 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 upper area of ​​the air outlet 312, and then flow into the room, so that the airflow can be prevented 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 the embodiment of the present application is not limited to this.

[0074] See also Figure 2In some embodiments, at least a portion of the inner wall surface of the air outlet channel 311 formed by the first heat-insulating 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 center line, and 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.

[0075] In this way, under the guiding effect 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, thereby reducing the possibility of condensation caused by excessive cold transfer between the panel body 31 and the airflow.

[0076] Furthermore, based on the arrangement in which a portion of the structure of the first thermal insulation component 33 extends into the upper area of ​​the air outlet 312 and a portion 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 portion 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, thereby better avoiding the transfer of cold air between the airflow and the panel body 31.

[0077] The panel structure 30 further includes an air guide plate (not shown in the figure), which is movably connected to the panel body 31 and disposed at the air outlet channel 311. It is understood that, based on the movably connected air guide plate to the panel body 31, the air guide plate can swing to guide the airflow flowing through the air outlet channel 311 to different areas of the room.

[0078] 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 condensation caused by temperature difference between the front and back of the air guide plate.

[0079] Please refer to Figure 1 to Figure 2 In some embodiments, the machine body 10 includes a wind wheel 15, and the wind wheel 15 is accommodated in the fan cavity. The airflow flowing into the fan cavity through the heat exchange cavity can be thrown toward the air outlet channel 311 by the wind wheel 15 under the drive of the wind wheel 15.

[0080] The air outlet channel 311 extends in the axial direction of the wind wheel 15. The first heat-insulating member 33 is at least formed as an inner wall surface in the air outlet channel 311 extending in the axial direction of the wind wheel 15. That is, the first heat-insulating member 33 may be formed as an inner wall surface in the air outlet channel 311 extending in the axial direction of the wind wheel 15, or the first heat-insulating member 33 may be formed not only as an inner wall surface in the air outlet channel 311 extending in the axial direction of the wind wheel 15, but also as an inner wall surface in the air outlet channel 311 extending perpendicular to the axis of the wind wheel 15, and the present application does not limit this.

[0081] It can be understood that the flow 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 to 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 cold energy of this part of the airflow with a larger flow rate can be better blocked from being transferred to the panel body 31.

[0082] Please refer to Figures 2 to 3 In some embodiments, the panel structure 30 further includes a reinforcement member 35. The reinforcement member 35 may be arranged in a long strip shape, and the reinforcement member 35 may be a sheet metal member, so as to have advantages such as better strength. Of course, the reinforcement member 35 may also be a plastic member, and better strength may be achieved by increasing the thickness of the reinforcement member 35.

[0083] The reinforcement 35 is connected to the side of the first thermal insulation component 33 that is 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, thereby 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.

[0084] Please refer to Figures 3 to 6 Further, a stepped groove 333 is formed on one side of the first heat-insulating member 33 away from the bottom plate 3131 of the panel body 31. The reinforcing member 35 is disposed in the stepped groove 333 and includes a first reinforcing portion 351 and a second reinforcing portion 353, wherein the second reinforcing portion 353 is connected to the first reinforcing portion 351 and has an angle with the first reinforcing portion 351. It is understandable that the first reinforcing portion 351 and the second reinforcing portion 353 can be connected to form an L-shape.

[0085] The first reinforcing portion 351 is disposed against the side wall of the stepped groove 333, and the second reinforcing portion 353 is disposed against the bottom wall of the stepped groove 333. Thus, the reinforcing effect of the reinforcing member 35 on the panel body 31 can be improved by the cooperation between the first reinforcing portion 351 and the second reinforcing portion 353.

[0086] Please refer to Figures 2 to 3In some structural forms, a threaded column 3135 is convexly provided on the upper surface of the panel body 31, and the reinforcement 35 and the first thermal insulation member 33 are both provided with avoidance holes corresponding to the threaded column 3135. Among them, a threaded fastener 37 is sequentially penetrated through the avoidance hole of the reinforcement 35, the avoidance hole of the first thermal insulation member 33 and the threaded column 3135 to fix the reinforcement 35, the first thermal insulation member 33 and the panel body 31. In this way, the connection strength between the reinforcement 35 and the panel body 31 can be improved by the threaded connection, thereby improving the reinforcing effect of the reinforcement 35 on the bottom plate 3131 of the panel body 31. In addition, compared with the form of opening a threaded hole on the panel body 31, the form of providing a threaded column 3135 and protruding the threaded column 3135 on 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.

[0087] Please refer to Figures 2 to 5 In some embodiments, a clamping groove 335 is formed on the side of the first heat-insulating member 33 facing the water receiving tray 13, and a clamping portion 131 is provided on the side of the water receiving tray 13 close to the air outlet channel 311. The clamping portion 131 is clamped on the clamping groove 335 and cooperates with the panel body 31 to clamp the first heat-insulating member 33. In this way, the first heat-insulating member 33 can be sealed and clamped between the water receiving tray 13 and the bottom plate 3131 of the panel body 31, thereby preventing the airflow from flowing from the water receiving tray 13 and the bottom plate 3131 of the panel body 31 to the panel body 31, so that the first heat-insulating member 33 can effectively block the cooling effect of the airflow, and the stability of the first heat-insulating member 33 between the water receiving tray 13 and the bottom plate 3131 of the panel body 31 can be improved by the clamping setting.
