Abstract
Description
Technical Field
[0001] This application relates to the field of air conditioning equipment technology, and in particular to a cabinet-type air conditioner indoor unit. Background Technology
[0002] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.
[0003] The air outlet of a floor-standing air conditioner is usually located on the front side of the casing, i.e., the front panel. Placing the display panel at the air outlet not only provides a suitable height for easy observation and operation by the user, but also makes the overall air conditioner unit more aesthetically pleasing.
[0004] However, when the air conditioner is cooling, the cold air discharged from the air outlet of the unit mixes with the hot and humid air in the room, which easily causes condensation to form on the display panel located at the air outlet of the unit. The condensation adheres to the display panel, which not only affects the display effect, but also causes the touch area to be unresponsive or unresponsive, affecting the user experience. Utility Model Content
[0005] This application discloses a cabinet-type air conditioner indoor unit that can prevent problems such as poor display function and unresponsive or insensitive touch function caused by condensation adhering to the display panel.
[0006] To achieve the above objectives, this application discloses a cabinet-type air conditioner indoor unit, comprising: a casing, wherein the casing includes: Front panel, wherein the front panel is provided with an air outlet; A panel bracket is disposed on the front panel and located below the front side of the air outlet. The panel bracket has a receiving space for accommodating display electrical components. The panel bracket includes: A front panel is disposed facing the front side of the housing, and the inner surface of the front panel has a mounting groove; The display panel is disposed on the front panel and is used to display information and receive touch operations. Heating assembly, the heating assembly comprising: A first heat-conducting plate is disposed in the receiving space and located above the display panel. At least a portion of the first heat-conducting plate is embedded in the mounting groove and is in thermal contact with the front panel. The first electric heating wire is embedded in the first heat-conducting plate and is in thermal contact with the first heat-conducting plate. The first electric heating wire is used to generate heat.
[0007] Thus, the first heat-conducting plate is located above the display panel, meaning the first heat-conducting plate and the display panel are arranged vertically and alternately on the inner side of the front panel. This layout effectively utilizes space and ensures the anti-condensation effect of the heating components. Because the upper part of the front panel is closer to the air outlet, the temperature is lower, and condensation is more likely to occur. Heating the upper area of the front panel can more effectively prevent water vapor condensation, thereby keeping the display panel area dry and clear. Moreover, the electric heating wire is embedded in the first heat-conducting plate and makes thermal contact with the heat-conducting plate. A columnar cavity can be set in the first heat-conducting plate to accommodate the electric heating wire. The electric heating wire is in close contact with the inner wall of the columnar cavity. The first heat-conducting plate can be made of materials with certain thermal conductivity, such as aluminum, thermally conductive rubber (a large number of highly thermally conductive microparticles are mixed into a rubber matrix (such as silicone rubber) to form a thermally conductive "pathway." Heat is quickly transferred through these filler particles, bypassing the non-thermally conductive rubber molecular chains, which gives the thermally conductive rubber good thermal conductivity), or thermally conductive plastic. The first heat-conducting plate not only provides mounting and fixing for the first electric heating wire, but also effectively conducts heat to the front panel. Furthermore, the first heat-conducting plate and the front panel can achieve surface-to-surface contact, which, compared to the point or line contact between the columnar first electric heating wire and the front panel, allows for more uniform heat transfer, improving heating efficiency and reducing the risk of localized overheating. Simultaneously, the inner surface of the front panel is provided with mounting grooves, and at least a portion of the first heat-conducting plate is embedded within these grooves. The distance between the portion of the first heat-conducting plate embedded in the mounting groove and the front surface (i.e., the outer surface) of the front panel is shorter, reducing the heat conduction path from the first heat-conducting plate to the front surface of the front panel. This allows heat from the first heat-conducting plate to be transferred to the outer surface of the front panel more quickly, effectively improving the heating response speed and reducing heat loss during heat transfer. This enhances the heating effect of the first heat-conducting plate on the front surface of the front panel. Since the front surface of the front panel is the area most prone to condensation, this further improves the anti-condensation effect of the heating assembly on the front panel.
[0008] As an optional implementation, the top of the first heat-conducting plate is disposed close to the top of the front plate; There are multiple first heating wires, which extend along both sides of the housing. The multiple first heating wires are arranged at intervals in the vertical direction, and the uppermost first heating wire is positioned close to the top of the first heat-conducting plate.
[0009] Thus, by setting the first heating wire to extend along the width of the casing, heat can be more evenly distributed across the lateral area of the inner surface of the front panel, effectively covering the upper area of the display panel and avoiding uneven condensation caused by localized temperature differences. The uppermost first heating wire, positioned close to the top of the first heat-conducting plate, prioritizes heating the area on the upper edge of the front panel where cold air tends to accumulate, further enhancing the anti-condensation effect. Furthermore, multiple first heating elements can be evenly distributed, or the first heating wires near the top of the first heat-conducting plate can be more densely packed to increase the heating intensity on the top of the front panel, corresponding to the area more prone to condensation, thus concentrating heat more on the top of the front panel. Moreover, positioning the first heating wire close to the top of the first heat-conducting plate, and vice versa, allows the first heating wire to be positioned near the area most in need of heating—the top area of the front panel where cold air first impacts, where the temperature is lowest, and where condensation is most likely to occur. This more effectively prevents excessive condensation from forming on the front panel, thus avoiding impacts on the display and touch performance of the display panel.
[0010] As an optional implementation, the distance d between the front surface of the front plate and the bottom surface of the mounting groove is 0.8 mm to 1.5 mm.
[0011] In this way, while ensuring the strength of the front panel, the heating path from the first heat-conducting plate to the front surface of the front panel can be reduced, the heating efficiency of the first heat-conducting plate to the front surface of the front panel can be improved, and a large amount of condensation can be avoided on the front surface of the front panel, or even completely avoided, so as to avoid condensation affecting the display and touch effects of the display panel.
[0012] As an optional implementation, the front wall of the first heat-conducting plate has a plurality of arc-shaped convex cylindrical surfaces, which correspond to the first electric heating wire; The bottom surface of the mounting groove of the front plate has multiple arc-shaped concave cylindrical surfaces, each arc-shaped convex cylindrical surface corresponds to the arc-shaped convex cylindrical surface, and each arc-shaped convex cylindrical surface is in contact with each arc-shaped concave cylindrical surface.
[0013] Thus, compared to an ideal planar contact, this curved surface contact effectively increases the contact area between the first heat-conducting plate and the front plate in three-dimensional space, significantly improving heat transfer efficiency. Specifically, the arc-shaped convex cylindrical surface corresponds to the first heating wire, allowing for a tight fit between the heating wire and the first heat-conducting plate during assembly, further enhancing thermal stability. It also minimizes the distance between the heating wire and the front wall of the first heat-conducting plate, further improving heating response speed and uniformity, ensuring efficient heat transfer to the condensation-prone areas of the front plate, and enhancing the anti-condensation effect.
[0014] As an optional implementation, the heating assembly further includes: A thermally conductive adhesive is disposed between the first thermally conductive plate and the front plate. The thermally conductive adhesive is bonded to the first thermally conductive plate and the front plate respectively, and makes thermal contact with the first thermally conductive plate and the front plate respectively.
[0015] In this way, the air gap between the first heat-conducting plate and the front plate can be filled by the thermally conductive adhesive, which can establish an efficient thermal bridge between the first heat-conducting plate and the front plate, greatly improving heating efficiency and allowing the front plate to obtain heat more quickly. Moreover, it eliminates the need for additional mechanical fasteners (such as screws and clips) to fix the heat-conducting plate, making the assembly process simpler, easier to automate, and reducing production costs. At the same time, the adhesive connection can provide a large area of uniform adhesion force, avoiding local stress concentration that may be caused by mechanical fastening, which can improve the reliability and long-term stability of the structure, effectively prevent the connection from loosening due to vibration or temperature cycling, and avoid the formation of gaps between the first heat-conducting plate and the front plate due to vibration and other factors, which would affect the heat transfer between the first heat-conducting plate and the front plate.
[0016] As an optional implementation, the area of thermal contact between the thermally conductive adhesive and the front plate is greater than the area of thermal contact between the first thermally conductive plate and the thermally conductive adhesive.
[0017] In this way, heat flows from the smaller first heat-conducting plate into the thermally conductive adhesive, and then immediately diffuses over a larger area onto the front panel. This avoids heat remaining concentrated in an area equal to the projected area of the first heat-conducting plate, achieving lateral expansion of heat flow. According to Fourier's law, with constant heat power, the larger the area, the lower the heat flux density (heat flux density refers to the heat power passing through a unit area). Lowering the heat flux density means that there will be no localized overheating areas on the front panel surface, resulting in a more uniform temperature and thus achieving effective anti-condensation at a lower overall temperature, thereby reducing energy consumption.
[0018] As an optional implementation, the panel bracket further includes: A top plate, which is connected above the front plate; The heating assembly also includes: A second heat-conducting plate is disposed in the accommodating space, and the top of the second heat-conducting plate is in thermal contact with the lower surface of the top plate. The second electric heating wire is embedded in the second heat-conducting plate and is used to generate heat.
[0019] This further reduces the risk of condensation on the panel support, preventing condensation from forming on the top panel and flowing onto the front panel, thus affecting the display and touch performance of the display panel. The first heat-conducting plate, first heating wire, second heat-conducting plate, and second heating wire provide multi-dimensional protection for the display panel. Furthermore, the front and top panel heating works in tandem; the heat generated by the top panel heats the surrounding air, creating an upward hot airflow. This hot airflow helps to prevent or weaken cold air from flowing directly along the top panel surface, indirectly reducing the load on the front panel heater. This effectively prevents condensation from accumulating on the display panel surface, significantly improving the reliability and user satisfaction of the air conditioning unit proposed in this application.
[0020] As an optional implementation, the connection between the top plate and the front plate has a heat-conducting groove; The front end of the second heat-conducting plate is connected to the front end of the first heat-conducting plate, and the connection between the second heat-conducting plate and the first heat-conducting plate has a heat-conducting protrusion. The first electric heating wire is disposed in the heat-conducting protrusion.
[0021] Thus, the second and first heat-conducting plates are connected to form a roughly "L"-shaped integrated structure, facilitating production and installation and improving production efficiency. Furthermore, one of the first heating wires is positioned at the connection point between the first and second heat-conducting plates; it's worth noting that this first heating wire also functions as the second heating wire. By heating the junction of the front and top plates with the first heating wire at the junction, i.e., heating the top of the front plate where heating is most needed, the surface temperature required for anti-condensation can be achieved in a shorter time and with lower total power, achieving rapid response and energy saving. Simultaneously, the combined design of the heat-conducting grooves and protrusions increases the heat conduction area at the junction of the first and second heat-conducting plates, and at the junction of the front and top plates. It also brings the first heating wire closer to the outer surface of the junction of the front and top plates, further enhancing the heat transfer efficiency between structures, reducing heat loss at the connection point, and resulting in a more uniform temperature distribution.
[0022] As an optional implementation, the heating assembly further includes: A heat insulation component is disposed in the accommodating space. A heating space is formed between the heat insulation component, the front plate, and the top plate. The first heat-conducting plate and the second heat-conducting plate are both disposed in the heating space. The heat insulation component is used to block heat transfer.
[0023] In this way, the heat insulation component can divide the housing space, creating a heating space between the front panel, top panel, and the heat insulation component. By placing the first and second heat-conducting plates within this heating space, heat transfer can be prevented to areas outside the heating space, thus avoiding overheating of other components and affecting the normal operation of the display panel and other parts. Furthermore, the heat insulation design reduces ineffective heat loss, allowing the heat generated by the first and second heating wires to be concentrated and diffused across the front and top panels, further improving heating efficiency and energy utilization.
[0024] As an optional implementation, the heating assembly further includes: A heat-insulating fastener is disposed in the receiving space, the heat-insulating fastener having: A pressure surface is provided around the peripheral edge of the heat insulation component to press the heat insulation component firmly against the inner wall of the panel support. A sealing mating surface is arranged around the periphery of the pressure surface. The sealing mating surface is in contact with the inner wall of the panel bracket to isolate the heating space from other areas within the receiving space.
[0025] In this way, the sealing mating surface surrounds the outer periphery of the low-pressure surface, forming a tight fit with the inner wall of the panel bracket, further improving the sealing reliability; the low-pressure surface is used to press against the edge of the heat insulation component, ensuring its stable fixation. This structure not only prevents heat leakage from the heating space, but also avoids displacement of the heat insulation component due to vibration or deformation, enhancing the overall assembly durability and consistency. At the same time, the precise fit between the sealing mating surface and the inner wall of the panel bracket effectively blocks the air convection path, further suppressing heat loss through gaps.
[0026] Compared with the prior art, the beneficial effects of this application are: The cabinet-type air conditioner indoor unit provided in this application embodiment includes a panel bracket. The panel bracket is located below the front side of the air outlet of the front panel. When cold air is discharged from the air outlet, condensation is easily generated on the front panel of the panel bracket. The condensation will affect the display and touch effect of the display panel on the front panel. At this time, the front panel can be heated by the first electric heating wire and the first heat conduction plate to avoid condensation on the front panel. Furthermore, the first heating wire and the first heat-conducting plate are located above the display panel. By directional heating of the area above the display panel, the condensation problem caused by cold air from the air outlet can be more effectively avoided. In addition, the first heating wire is embedded in the first heat-conducting plate, and the front surface of the first heat-conducting plate can be flat, allowing it to make full contact with the inner surface of the front panel. Compared with the cylindrical surface of the heating wire, this significantly increases the heat-conducting contact area with the front panel, effectively improving the heating effect on the front panel. In particular, some of the first heat-conducting plate is embedded in the mounting groove on the inner surface of the front panel, making the distance between the first heat-conducting plate and the front surface of the front panel shorter. This allows heat to reach the front surface of the front panel faster and more efficiently, thus establishing the shortest and most efficient heat conduction path from the heat source to the surface to be heated. This effectively prevents condensation from forming on the front panel and avoids condensation from accumulating on the front surface of the display panel, which would affect the display and touch effects, thereby improving the user experience.

Detailed Implementation
[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0031] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0032] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0033] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0034] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts.

[0035] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.
[0036] In air conditioning unit cabinets, the air outlet is usually located on the front side of the casing, i.e., the front panel. The display panel is located at the air outlet, specifically at the bottom front of the outlet. The display panel's casing is crescent-shaped, covering the bottom of the circular air outlet. The outlet's sealing plate can rise from the bottom to block it. Combined with the crescent-shaped display panel casing, this creates a "bright moon rising over the sea" aesthetic, significantly enhancing the overall appearance of the air conditioning unit. Furthermore, the display panel's height at this position is ideal for user observation and operation.
[0037] However, when the air conditioner is cooling, the cold air discharged from the air outlet of the unit mixes with the hot and humid air in the room, which easily causes condensation on the display panel located at the air outlet. This is especially true when there is a deflector grille at the air outlet. When the deflector grille guides the cold air downwards, a large amount of condensation is generated. The condensation adheres to the display panel, which not only affects the display effect, but also causes touch sensitivity or unresponsiveness when the user touches the display area, affecting the user experience.
[0038] Based on this, this application discloses an air conditioner cabinet unit that can reduce or even avoid condensation on the surface of the display panel, prevent condensation on the display panel surface from affecting the display effect and touch effect of the display panel, and improve the user experience.
[0039] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.
[0040] Please see Figures 1 to 6 , Figure 1 This is a schematic diagram of the structure of the air conditioner cabinet unit disclosed in the embodiments of this application. Figure 2 This is a schematic diagram of the structure of the front panel 110 disclosed in an embodiment of this application. Figure 3 for Figure 2 Enlarged structural diagram at point A in the middle. Figure 4 This is a schematic diagram of the structure of the air outlet 111, panel bracket 120, and heating component 200 disclosed in the embodiments of this application. Figure 5 This is a schematic cross-sectional view of the air outlet 111, panel bracket 120, and heating assembly 200 disclosed in the embodiments of this application. Figure 6 for Figure 5 Enlarged structural diagram at point B. This application discloses an air conditioner cabinet unit, which includes a housing 100 comprising: a front panel 110 and a panel bracket 120. The front panel 110 is provided with an air outlet 111. The panel bracket 120 is disposed on the front panel 110 and located below and in front of the air outlet 111. The panel bracket 120 has a receiving space for housing display devices. The panel bracket 120 includes a front plate 121 and a display panel 122. The front plate 121 faces the front of the housing 100, and the inner surface of the front plate 121 has a mounting groove 121. 1; The display panel 122 is disposed on the front panel 121 and is used to display information and receive touch operations; The heating assembly 200 includes a first heat-conducting plate 210 and a first electric heating wire 220. The first heat-conducting plate 210 is disposed in the receiving space and is located above the display panel 122. At least a portion of the first heat-conducting plate 210 is embedded in the mounting groove 1211 and is in thermal contact with the front panel 121; The first electric heating wire 220 is embedded in the first heat-conducting plate 210 and is in thermal contact with the first heat-conducting plate 210. The first electric heating wire 220 is used to generate heat.
[0041] In some embodiments, the air conditioner cabinet unit includes a housing 100, the housing 100 is provided with a front panel 110, and the front panel 110 is provided with an air outlet 111. The heating or cooling air generated by the air conditioner cabinet unit can enter the room through the air outlet 111. The air outlet 111 can be located near the top of the front panel 110 to avoid the heating or cooling air blowing directly on the human body, which can improve the user experience.
[0042] In some embodiments, the housing 100 has a housing accommodating cavity inside, and a heat exchanger is provided in the housing 100 accommodating cavity. The heat exchanger is used to exchange heat with the airflow flowing through the air inlet of the housing 100. When the air conditioner is cooling, the low-temperature refrigerant flowing in the heat exchanger absorbs the heat in the airflow and cools the air. When heating, the high-temperature refrigerant releases heat to the airflow and warms the air.
[0043] In some embodiments, the panel bracket 120 is located at the bottom of the front side of the air outlet 111 of the housing 100, and the display panel 122 is located on the front plate 121 of the panel bracket 120. The panel bracket 120 can be approximately one-fifth of a circle, i.e., a crescent shape. Placing the display panel 122 in this position can greatly improve the aesthetics of the air conditioner and make it more popular with users. The display panel 122 can display various information of the air conditioner and receive touch operations to control the air conditioner.
[0044] In some embodiments, the heating component 200 includes a first heat-conducting plate 210 and a first electric heating wire 220. The first electric heating wire 220 can be a nickel-chromium wire or an iron-chromium-aluminum wire, etc. The first electric heating wire 220 can be electrically connected to the controller of the air conditioner unit through a wiring harness, and the controller can regulate its on / off state. When the air conditioner unit is cooling, the controller controls the first electric heating wire to be powered on. After the first electric heating wire 220 is powered on, it generates heat. The heat is conducted to the front panel 121 through the first heat-conducting plate 210, which can heat the front panel 121 and prevent the front panel 121 from generating a large amount of condensation, which would affect the display and touch effects of the display panel 122.
[0045] In some embodiments, the first heat-conducting plate 210 is located above the display panel 122, that is, the first heat-conducting plate 210 and the display panel 122 are arranged alternately in the vertical direction on the inner side of the front panel 121. This layout can effectively utilize space and ensure the anti-condensation effect of the heating component 200. Because the upper part of the front panel 121 is closer to the air outlet 111, the temperature is lower and condensation is more likely to occur. Heating the upper area of the front panel 121 can more effectively prevent water vapor condensation, thereby keeping the area of the display panel 122 dry and clear.
[0046] In some embodiments, the heating wire is embedded in the first heat-conducting plate 210 and makes thermal contact with the heat-conducting plate. A columnar cavity for accommodating the heating wire can be provided within the first heat-conducting plate 210, with the heating wire in close contact with the inner wall of the columnar cavity. The first heat-conducting plate 210 can be made of aluminum, thermally conductive rubber (a rubber matrix (such as silicone rubber) mixed with a large number of highly thermally conductive microparticles to form a thermally conductive "pathway." Heat is rapidly transferred through these filler particles, bypassing the non-thermally conductive rubber molecular chains, thus giving the thermally conductive rubber good thermal conductivity), thermally conductive plastic, or other materials with a certain degree of thermal conductivity. The first heat-conducting plate 210 not only provides mounting and fixing for the first heating wire 220, but also effectively conducts heat to the front plate 121. Moreover, the first heat-conducting plate 210 and the front plate 121 can achieve surface-to-surface contact, which, compared to the point or line contact between the columnar first heating wire 220 and the front plate 121, can transfer heat more evenly, improve heating efficiency, and reduce the risk of local overheating.
[0047] In some embodiments, the inner surface of the front panel 121 is provided with a mounting groove 1211, and at least a portion of the first heat-conducting plate 210 is embedded in the mounting groove 1211. The distance between the portion of the first heat-conducting plate 210 embedded in the mounting groove 1211 and the front surface (i.e., the outer surface) of the front panel 121 is shorter, which can reduce the heat conduction path from the first heat-conducting plate 210 to the front surface of the front panel 121, so that the heat of the first heat-conducting plate 210 can be transferred to the outer surface of the front panel 121 more quickly, effectively improving the heating response speed and reducing heat loss during the heat transfer process, thereby improving the heating effect of the first heat-conducting plate 210 on the front surface of the front panel 121. The front surface of the front panel 121 is the location where condensation is more likely to occur, thereby further improving the anti-condensation effect of the heating assembly 200 on the front panel 121.
[0048] According to an embodiment of this application, the air conditioner cabinet unit includes a panel bracket 120, which is disposed below the front side of the air outlet 111 of the front panel 110. When cold air is discharged from the air outlet 111, condensation is easily generated on the front panel 121 of the panel bracket 120. The condensation will affect the display and touch effect of the display panel 122 located on the front panel 121. At this time, the front panel 121 can be heated by the first electric heating wire 220 and the first heat-conducting plate 210 to prevent condensation from forming on the front panel 121. Furthermore, the first heating wire 220 and the first heat-conducting plate 210 are located above the display panel 122. By directional heating of the area above the display panel 122, the condensation problem on the panel caused by cold air from the air outlet 111 can be more effectively avoided. In addition, the first heating wire 220 is embedded in the first heat-conducting plate 210, and the front surface of the first heat-conducting plate 210 can be flat, allowing it to make full-face contact with the inner surface of the front panel 121. Compared with the cylindrical surface of the heating wire, this significantly increases the heat-conducting contact area with the front panel 121, effectively improving the heating efficiency of the front panel 121. As a result, especially since part of the first heat-conducting plate 210 is embedded in the mounting groove 1211 on the inner surface of the front plate 121, the distance between the first heat-conducting plate 210 and the front surface of the front plate 121 is shorter, allowing heat to reach the front surface of the front plate 121 faster and more efficiently. This establishes the shortest and most efficient heat conduction path from the heat source to the surface that needs to be heated, thereby effectively preventing condensation from forming on the front plate 121 and preventing condensation from accumulating on the front surface of the display panel 122, which would affect the display and touch effects of the display panel 122, thus improving the user experience.
[0049] refer to Figure 6 and Figure 9 , Figure 9 This is a schematic diagram of the structure of the first heating plate, the second heating plate, the first heating wire, and the second heating wire disclosed in an embodiment of this application. In some embodiments, the top of the first heat-conducting plate 210 is disposed near the top of the front plate 121; there are multiple first heating wires 220, which extend along both sides of the housing 100, and the multiple first heating wires 220 are arranged at intervals in the vertical direction, with the uppermost first heating wire 220 disposed near the top of the first heat-conducting plate 210.
[0050] Specifically, there can be multiple first heating wires 220. These multiple heating wires can extend vertically along the housing 100 and be arranged along the width of the housing 100, or they can extend along the width of the housing 100 and be arranged along the height of the housing 100. Setting the first heating wires 220 to extend along the width of the housing 100 allows for a more even distribution of heat in the lateral area of the inner surface of the front panel 121, effectively covering the upper area of the display panel 122 and avoiding uneven condensation caused by local temperature differences. The uppermost first heating wire 220 is positioned close to the top of the first heat-conducting plate 210, which can preferentially heat the area along the upper edge of the front panel 121 where cold air tends to accumulate, further improving the anti-condensation effect. In addition, the multiple first electric heating elements can be evenly distributed, or the first electric heating wires 220 near the top of the first heat-conducting plate 210 can be more densely packed to increase the heating intensity on the top of the front plate 121, which corresponds to the phenomenon that condensation is more likely to occur on the top of the front plate 121, so that more heat is concentrated on the top of the front plate 121.
[0051] Furthermore, the first heating wire 220 is positioned close to the top of the first heat-conducting plate 210, and the top of the first heat-conducting plate 210 is positioned close to the top of the front panel 121. This allows the first heating wire 220 to be positioned close to the area that needs the most heating, namely the top area of the front panel 121 where the cold air first impacts, the temperature is lowest, and condensation is most likely to occur. This can more effectively prevent the front panel 121 from generating a large amount of condensation, which would affect the display and touch effects of the display panel 122.
[0052] refer to Figure 7 , Figure 7 for Figure 6 Enlarged structural diagram at point C. In some embodiments, the distance d between the front surface of the front panel 121 and the bottom surface of the mounting groove 1211 is 0.8 mm to 1.5 mm.
[0053] Specifically, a distance d less than 0.8 mm between the front surface of the front panel 121 and the bottom surface of the mounting groove 1211 will affect the strength of the front panel 121. A distance d greater than 1.5 mm will affect the heat transfer between the front surface of the front panel 121 and the bottom surface of the mounting groove 1211, reducing the heating efficiency of the first heat-conducting plate 210 on the front surface of the front panel 121. The distance d between the front surface of the front panel 121 and the bottom surface of the mounting groove 1211 proposed in this embodiment is 0.8 mm to 1.5 mm, which can be 1.2 mm. This can reduce the heating path from the first heat-conducting plate 210 to the front surface of the front panel 121 while ensuring the strength of the front panel 121, improve the heating efficiency of the first heat-conducting plate 210 on the front surface of the front panel 121, avoid a large amount of condensation on the front surface of the front panel 121, or even completely avoid condensation on the front surface of the front panel 121, thereby avoiding condensation affecting the display and touch effects of the display panel 122.
[0054] refer to Figures 10 to 13 , Figure 10 This is a schematic diagram of another first heating plate, second heating plate, first heating wire, and second heating wire disclosed in an embodiment of this application. Figure 11 This is a schematic diagram of another panel bracket 120 and part of the air outlet 111 disclosed in an embodiment of this application. Figure 12 This is a cross-sectional schematic diagram of another air outlet 111, panel bracket 120, and heating assembly 200 disclosed in an embodiment of this application. Figure 13 for Figure 12 An enlarged structural schematic diagram at point E. In some embodiments, the front wall of the first heat-conducting plate 210 has multiple arc-shaped convex cylindrical surfaces 211, which correspond to the first electric heating wire 220; the bottom surface of the mounting groove 1211 of the front plate 121 has multiple arc-shaped concave cylindrical surfaces 12111, each arc-shaped convex cylindrical surface 211 corresponding to the arc-shaped convex cylindrical surface 211, and each arc-shaped convex cylindrical surface 211 fitting against each arc-shaped concave cylindrical surface 12111.
[0055] Specifically, the bottom surfaces of the first heat-conducting plate 210 and the mounting groove 1211 can be mated together as a plane to form a tight thermally conductive contact, or they can be mated together by an arc-shaped convex cylindrical surface 211 and an arc-shaped concave cylindrical surface 12111 to form a conformal contact for heat conduction. When the two curved surfaces are pressed together, the contact stress is significantly higher than that of the surrounding planar area. This higher contact pressure squeezes out the air gaps between the interfaces, and air is an excellent thermal insulator, thus greatly reducing the contact thermal resistance. Moreover, compared to an ideal planar contact, this curved surface contact actually increases the effective contact area between the first heat-conducting plate 210 and the front plate 121 in three-dimensional space, significantly improving heat transfer efficiency. The arc-shaped convex cylindrical surface 211 corresponds to the first electric heating wire 220, which allows the first electric heating wire 220 and the first heat-conducting plate 210 to fit tightly during assembly, further improving thermal conductivity stability. It also minimizes the distance between the first electric heating wire 220 and the front wall of the first heat-conducting plate 210, further improving the heating response speed and uniformity, ensuring efficient heat transfer to the condensation-prone area of the front plate 121, and enhancing the anti-condensation effect.
[0056] refer to Figure 6 and Figure 7 In some embodiments, the heating assembly 200 further includes a thermally conductive adhesive 250 disposed between the first heat-conducting plate 210 and the front plate 121. The thermally conductive adhesive 250 is bonded to the first heat-conducting plate 210 and the front plate 121 respectively, and is in thermal contact with the first heat-conducting plate 210 and the front plate 121 respectively.
[0057] Specifically, the first heat-conducting plate 210 can be directly bonded to the front plate 121, or it can be bonded together using a thermally conductive adhesive 250, which can be made of aluminum foil. The thermally conductive adhesive 250 fills the air gap between the first heat-conducting plate 210 and the front plate 121, creating a highly efficient thermal bridge between them, greatly improving heating efficiency and allowing the front plate 121 to gain heat more quickly. Furthermore, it eliminates the need for additional mechanical fasteners (such as screws or clips) to secure the heat-conducting plate, simplifying the assembly process, facilitating automation, and reducing production costs. The adhesive connection provides a large area of uniform adhesion, avoiding localized stress concentration that may result from mechanical fastening, thus improving structural reliability and long-term stability. It effectively prevents loosening of the connection due to vibration or temperature cycling, and avoids gaps between the first heat-conducting plate 210 and the front plate 121 caused by vibration or other factors, which could affect heat transfer between them. In addition, thermal grease or similar materials can be applied between the thermally conductive adhesive 250 and the first thermally conductive plate 210, and between the thermally conductive adhesive 250 and the front plate 121, to further reduce the problem of poor heat transfer caused by gaps due to uneven adhesion.
[0058] refer to Figure 6 and Figure 7 In some embodiments, the area of thermal contact between the thermally conductive adhesive 250 and the front plate 121 is greater than the area of thermal contact between the first thermally conductive plate 210 and the thermally conductive adhesive 250.
[0059] Specifically, the thermally conductive contact area between the thermally conductive adhesive 250 and the front panel 121 can be less than or equal to the thermally conductive contact area between the first thermally conductive plate 210 and the thermally conductive adhesive 250, or it can be greater than the thermally conductive contact area between the first thermally conductive plate 210 and the thermally conductive adhesive 250. Heat flows from the smaller area of the first thermally conductive plate 210 into the thermally conductive adhesive 250, and then immediately diffuses over a larger area onto the front panel 121. This avoids heat remaining concentrated in an area equal to the projected area of the first thermally conductive plate 210, achieving lateral expansion of heat flow. According to Fourier's law, with constant heat power, the larger the area, the lower the heat flux density (heat flux density refers to the heat power passing through a unit area). Reducing the heat flux density means that there will be no localized overheating areas on the surface of the front panel 121, resulting in a more uniform temperature. This leads to effective anti-condensation at a lower overall temperature, achieving the technical effect of reducing energy consumption.
[0060] refer to Figure 6In some embodiments, the panel support 120 further includes a top plate 123, which is connected above the front plate 121; the heating assembly 200 further includes a second heat-conducting plate 230 and a second electric heating wire 240, the second heat-conducting plate 230 is disposed in the receiving space, and the top of the second heat-conducting plate 230 is in thermal contact with the lower surface of the top plate 123; the second electric heating wire 240 is embedded in the second heat-conducting plate 230 and is used to generate heat.
[0061] Specifically, the first heat-conducting plate 210 and the first electric heating wire 220 can be used to heat the front panel 121, or a second heat-conducting plate 230 and a second electric heating wire 240 can be added to heat the top panel 123. Heating the top panel 123 with the second heat-conducting plate 230 and the second electric heating wire 240 can further reduce the risk of condensation on the panel support 120, and prevent condensation from forming on the top panel 123 and flowing to the front panel 121, thus affecting the display and touch effects of the display panel 122. The first heat-conducting plate 210, the first electric heating wire 220, the second heat-conducting plate 230, and the second electric heating wire 240 provide multi-dimensional protection for the display panel 122. Moreover, the heating of the front panel 121 and the heating of the top panel 123 can work together. The heat generated by the heating of the top panel 123 will heat the air nearby, forming an upward hot airflow. This hot airflow helps to prevent or weaken the cold air from flowing directly against the surface of the top panel 123, thereby indirectly reducing the load on the heater of the front panel 110. This effectively prevents condensation from accumulating on the surface of the display panel 122, which can significantly improve the reliability and user satisfaction of the air conditioner cabinet unit proposed in this application.
[0062] refer to Figure 13 In some embodiments, the connection between the top plate 123 and the front plate 121 has a heat-conducting groove 124; the front end of the second heat-conducting plate 230 is connected to the front end of the first heat-conducting plate 210, and the connection between the second heat-conducting plate 230 and the first heat-conducting plate 210 has a heat-conducting protrusion 260; the first electric heating wire 220 is disposed in the heat-conducting protrusion 260.
[0063] Specifically, the second heat-conducting plate 230 and the first heat-conducting plate 210 are connected to form an approximately "L"-shaped integrated structure, which facilitates production and installation and helps improve production efficiency. Furthermore, one of the first electric heating wires 220 is located at the connection between the first heat-conducting plate 210 and the second heat-conducting plate 230. It is worth noting that this first electric heating wire 220 is also equivalent to the second electric heating wire 240. By heating the junction of the front plate 121 and the top plate 123 with the first electric heating wire 220 at the junction, i.e., heating the top position of the front plate 121 where heating is most needed, the surface temperature required for anti-condensation can be achieved in a shorter time and with lower total power, realizing rapid response and energy saving. Meanwhile, the combined design of the heat-conducting groove 124 and the heat-conducting protrusion 260 can increase the heat-conducting area at the junction of the first heat-conducting plate 210 and the second heat-conducting plate 230, and at the junction of the front plate 121 and the top plate 123. It also makes the first electric heating wire 220 at this position closer to the outer surface of the junction of the front plate 121 and the top plate 123, which can further enhance the heat conduction efficiency between structures, reduce heat loss at the connection, and make the temperature distribution more uniform.
[0064] refer to Figures 6 to 8 , Figure 8 for Figure 6 An enlarged structural schematic diagram at point D. In some embodiments, the heating assembly 200 further includes a heat insulation member 270, which is disposed in the receiving space. A heating space is formed between the heat insulation member 270, the front plate 121, and the top plate 123. The first heat-conducting plate 210 and the second heat-conducting plate 230 are both disposed in the heating space. The heat insulation member 270 is used to block heat transfer.
[0065] Specifically, the heating component 200 can be directly placed in the receiving space, or a heat insulation component 270 can be provided. The heat insulation component 270 can be made of heat-insulating materials, such as heat-insulating sponge or heat-insulating foam. The heat insulation component 270 can divide the receiving space, forming a heating space between the front panel 121, the top panel 123, and the heat insulation component 270. After placing the first heat-conducting plate 210 and the second heat-conducting plate 230 in the heating space, heat can be prevented from being transferred to areas outside the receiving space, causing other components in the receiving space to overheat and affecting the normal operation of the display panel 122 and other components. Moreover, the design of the heat insulation component 270 can reduce the ineffective loss of heat, allowing the heat generated by the first electric heating wire 220 and the second electric heating wire 240 to be concentrated and diffused to the front panel 121 and the top panel 123, further improving heating efficiency and energy utilization.
[0066] refer to Figures 6 to 8In some embodiments, the heating assembly 200 further includes a heat insulation fastener 280 disposed in the receiving space. The heat insulation fastener 280 has a pressing surface 281 and a sealing mating surface 282. The pressing surface 281 is disposed around the peripheral edge of the heat insulation component 270 and is used to press the heat insulation component 270 against the inner wall of the panel support 120. The sealing mating surface 282 is disposed around the periphery of the pressing surface 281 and is in contact with the inner wall of the panel support 120 to isolate the heating space from other areas within the receiving space.
[0067] Specifically, the heat insulation component 270 can be directly adhered to the inner wall of the panel bracket 120, or it can be fixed using the heat insulation fastener 280. The heat insulation fastener 280 can be made of rigid heat insulation material, such as glass fiber reinforced PPS (polyphenylene sulfide) or PEEK (polyether ether ketone) foam. The heat insulation fastener 280 is arranged around the periphery of the heat insulation component 270. The heat insulation fastener 280 can have a gradient mounting surface, which can include a low-pressure surface and a sealing mating surface 282. The sealing mating surface 282 surrounds the outer periphery of the low-pressure surface and forms a tight fit with the inner wall of the panel bracket 120, further improving the sealing reliability. The low-pressure surface is used to press against the edge of the heat insulation component 270 to ensure its stable fixation. This structure not only prevents heat leakage from the heating space, but also avoids displacement of the heat insulation component 270 due to vibration or deformation, enhancing the overall assembly durability and consistency. Meanwhile, the precise fit between the sealing mating surface 282 and the inner wall of the panel bracket 120 effectively blocks the air convection path, further suppressing heat loss through the gaps.
