[0036] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0037] This application provides an antibacterial and antifungal sheet 2 (such as...). Figure 5 (as shown) and water receiving tray structure (such as) Figures 9 to 12 (As shown). The drip tray structure includes: a drip tray component 1 and an antibacterial and anti-mildew sheet 2. The shape of the antibacterial and anti-mildew sheet 2 is adapted to the shape of at least a portion of the inner wall surface of the drip tray's drip groove 11, so that the antibacterial and anti-mildew sheet 2 can be installed on and cover at least a portion of the inner wall surface of the drip groove 11. The drip tray component 1 can be, but is not limited to, an injection-molded part. The preparation method of the antibacterial and anti-mildew layer is not limited and can be spraying, coating, electroplating, chemical coating, deposition, etc. Accordingly, the antibacterial and anti-mildew layer can be in the form of a coating, plating, deposition layer, etc.

[0038] The water tray component 1 is equipped with a water trough 11. Besides the function of the water trough 11, the water tray component 1 can also have other functions. For example, for a wall-mounted air conditioner indoor unit, the water trough 11 can be installed on the chassis, thus the chassis is the water tray component 1. However, in addition to the function of the water trough 11, the water tray component 1 also functions as a chassis (such as supporting other components or forming part of the air duct 8). However, because the inner wall of the water trough 11 comes into contact with condensate, it is prone to mold and bacterial growth, which can be discharged into the indoor space with the airflow, affecting user health. Therefore, it needs to be mold-proof and antibacterial.

[0039] like Figure 3 and Figure 11 As shown, the antibacterial and anti-mold sheet 2 is installed on the inner wall of the water receiving tank 11 and covers at least a portion of the inner wall of the water receiving tank 11. The antibacterial and anti-mold sheet 2 includes a sheet-like substrate and an antibacterial and anti-mold layer disposed on the substrate. The antibacterial and anti-mold layer is located on the surface of the substrate facing away from the inner wall of the water receiving tank 11. The antibacterial and anti-mold layer faces the inside of the water receiving tank 11 and is in direct contact with the condensate in the water receiving tank 11, thus having an antibacterial and anti-mold effect, which helps to inhibit mold growth and bacterial proliferation in the water receiving tank 11.

[0040] This embodiment of the application, by installing an antibacterial and anti-mold sheet 2 on the inner wall of the water receiving tank 11, can inhibit mold growth and bacterial proliferation on the inner wall of the water receiving tank 11, thereby protecting the user's health. Furthermore, the antibacterial and anti-mold sheet 2 achieves its antibacterial and anti-mold effect using its own antibacterial and anti-mold layer, requiring no electricity, thus eliminating the need for users to perform regular sterilization, thereby improving the user experience.

[0041] Furthermore, compared to the solution of adding antibacterial and antifungal additives during the injection molding process of the water tray component to make the entire water tray component 1 have antibacterial and antifungal effects, this solution only needs to make at least a part of the inner wall surface of the water tray 11 have antibacterial and antifungal effects, which is beneficial to reducing the cost of the water tray structure and reducing the cost of the air conditioner 100.

[0042] In some exemplary embodiments, the antibacterial and antifungal layer is a polytetrafluoroethylene (PTFE) coating with added antibacterial and antifungal additives. These additives can be, but are not limited to, titanium ions, silver ions, zinc ions, or other additives with antibacterial and antifungal effects. PTFE has good hydrophobicity, making it difficult for bacteria and dirt to adhere to the surface of the antibacterial and antifungal layer; instead, they are carried away by dripping condensate, thus improving the self-cleaning effect of the antibacterial and antifungal layer. The antibacterial and antifungal additives provide good antibacterial and antifungal effects to achieve the antibacterial and antifungal function.

[0043] This solution only requires setting antibacterial and anti-mildew additives within the antibacterial and anti-mildew layer, eliminating the need to add them throughout the entire drip tray. This reduces the amount of antibacterial and anti-mildew additives needed, lowers the cost of the drip tray structure, and consequently reduces the cost of the air conditioner 100.

[0044] In other embodiments, the antibacterial and antifungal layer is an organic paint coating, such as an epoxy resin coating, a fluorocarbon resin coating, or a fluorocarbon-modified acrylic polyurethane resin coating, which can also achieve antibacterial and antifungal effects.

[0045] In some exemplary embodiments, the substrate is a metal substrate. Metal substrates have good strength and rigidity, and are easy to process into a shape that fits the water receiving tank 11, facilitating the stable coverage of the antibacterial and anti-mildew sheet 2 on the inner wall of the water receiving tank 11. Furthermore, compared to plastic parts, metal itself has better antibacterial and anti-mildew properties, thus improving the antibacterial and anti-mildew effect of the antibacterial and anti-mildew sheet 2.

[0046] In some embodiments, the substrate is a stainless steel substrate, which is less prone to rusting, thus reducing the risk of mold and bacterial growth in the water tank 11. In other embodiments, the substrate is an aluminum alloy substrate.

[0047] Of course, the substrate can also be other materials, such as copper alloy substrate or plastic substrate.

[0048] In some exemplary embodiments, such as Figure 3 and Figure 11 As shown, the water tray structure also includes a fixing frame 3. The fixing frame 3 is fixedly connected to the water tray component 1, and the antibacterial and anti-mildew sheet 2 is sandwiched between the fixing frame 3 and the inner wall of the water tank 11.

[0049] During installation, the antibacterial and anti-mold sheet 2 can be placed in the water receiving tank 11 first, then the fixing bracket 3 can be pressed onto the antibacterial and anti-mold sheet 2, and then the fixing bracket 3 can be fixedly connected to the water receiving tray component 1 to achieve the installation and fixation of the antibacterial and anti-mold sheet 2. This solution simplifies the structure of the antibacterial and anti-mold sheet 2, eliminating the need for drilling holes or setting clips on the antibacterial and anti-mold sheet 2.

[0050] Of course, the connection method between the antibacterial and anti-mildew sheet 2 and the air duct 8 is not limited to the snap-fit ​​method. For example, the antibacterial and anti-mildew sheet 2 can be bonded to the inner wall of the water receiving tank 11, that is, it can be fixed to the inner wall of the water receiving tank 11 by adhesive. Alternatively, the antibacterial and anti-mildew sheet 2 can also be fixed to the inner wall of the water receiving tank 11 by fasteners (such as screws), welding, etc.

[0051] In some exemplary embodiments, such as Figure 4 and Figure 12 As shown, the inner wall of the water receiving tank 11 includes a first side wall 111 and a second side wall 112 arranged at intervals, and a bottom wall 113 connecting the first side wall 111 and the second side wall 112. Figure 5 As shown, the antibacterial and antifungal sheet 2 has a first side portion 21 and a second side portion 22 arranged at relatively intervals, and a bottom portion 23 connecting the first side portion 21 and the second side portion 22. The first side portion 21 is attached to the first sidewall 111, the second side portion 22 is attached to the second sidewall 112, and the bottom portion 23 is attached to the bottom wall 113, as shown. Figure 4 and Figure 12 As shown. This allows both the bottom wall 113 and the side walls of the water receiving tank 11 to have antibacterial and anti-mildew effects. The height of the first side wall 111 can be equal to or lower than the height of the first side portion 21, because the water level in the water receiving tank 11 is generally lower than the height of the first side wall 111. Similarly, the height of the second side wall 112 can be equal to or lower than the height of the second side portion 22.

[0052] like Figure 6 As shown, the fixing frame 3 includes a first abutting part 31, a second abutting part 32, and a third abutting part 33. The first abutting part 31 abuts against the first side part 21, the second abutting part 32 abuts against the second side part 22, and the third abutting part 33 abuts against the third abutting part 33, as shown. Figure 4 and Figure 12 As shown. This allows for multiple fixation points on the antibacterial and antifungal sheet 2, resulting in a better fixation effect.

[0053] In some exemplary embodiments, such as Figure 4 As shown, the mounting bracket 3 also includes a support plate 34 spaced apart from the bottom 23, and the support plate 34 is configured to support the heat exchanger 5. By supporting the heat exchanger 5 with the support plate 34, the structure of the water receiving tank 11 can be simplified.

[0054] like Figures 6 to 8 As shown, the first abutting part 31, the second abutting part 32, and the third abutting part 33 protrude from the support plate 34. The support plate 34 is provided with a water passage hole 341, as shown. Figure 6 and Figure 8 As shown. In this way, the condensate dripping from heat exchanger 5 can enter the water receiving tank 11 through water hole 341.

[0055] Among them, such as Figure 6 and Figure 8 As shown, there can be multiple water passage holes 341, and these multiple water passage holes 341 can be spaced apart along the length of the support plate 34. The shape of the water passage holes 341 is not limited, and can be circular, square, triangular or other shapes.

[0056] In some embodiments, such as Figure 4 and Figure 12 As shown, the bottom wall 113 includes a first sub-wall 1131, a second sub-wall 1132, and a third sub-wall 1133 that are stepped and connected in sequence. The bottom 23 includes a first sub-section 231, a second sub-section 232, and a third sub-section 233 that are stepped and connected in sequence. The first sub-section 231 is attached to the first sub-wall 1131, the second sub-section 232 is attached to the second sub-wall 1132, and the third sub-section 233 is attached to the third sub-wall 1133, so that the bottom 23 of the antibacterial and anti-mildew sheet 2 is tightly attached to the bottom wall 113 of the water receiving tank 11.

[0057] like Figure 7 and Figure 12 As shown, the third abutting part 33 includes a first sub-abutting part 331 and a second sub-abutting part 332. The first sub-abutting part 331 abuts against the first sub-part 231, and the second sub-abutting part 332 abuts against the third sub-part 233. This allows for multi-part fixation of the bottom 23 of the antibacterial and anti-mildew sheet 2, resulting in a better fixation effect.

[0058] Among them, such as Figure 12 As shown, the first sub-abutment portion 331 can be perpendicular or substantially perpendicular to the first sub-portion 231, and the second sub-abutment portion 332 can be perpendicular or substantially perpendicular to the second sub-portion 232, thus achieving a better fixation effect on the antibacterial and antifungal sheet 2.

[0059] In some exemplary embodiments, such as Figure 6As shown, the first abutting part 31 and the second abutting part 32 are connected as one piece along the width direction of the support plate 34, forming a plate-like structure extending along the width direction of the support plate 34.

[0060] In this way, the first abutting part 31 and the second abutting part 32 can not only abut and fix the antibacterial and anti-mildew patch, but also act as a transverse reinforcing rib, which helps to prevent the support plate 34 from deforming.

[0061] Among them, such as Figure 6 As shown, there can be multiple first abutment portions 31 and multiple second abutment portions 32. Multiple first abutment portions 31 are spaced apart along the length direction of the support plate 34, and multiple second abutment portions 32 are spaced apart along the length direction of the support plate 34. This forms multiple transverse reinforcing ribs extending along the width direction of the support plate 34 to improve the reinforcement effect on the support plate 34.

[0062] In some exemplary embodiments, such as Figure 6 and Figure 7 As shown, the third abutment portion 33 includes a plate-like structure extending along the length of the support plate 34. Thus, the third abutment portion 33 can both abut and fix the antibacterial and anti-mildew patch, and also act as a longitudinal reinforcing rib, which helps prevent deformation of the support plate 34.

[0063] In some embodiments, the third abutment portion 33 is provided with a water inlet 334, such as Figure 6 As shown. This allows the water in the water receiving tank 11 to flow between the two sides of the third abutment 33, which helps to prevent overflow due to excessive water on one side of the third abutment 33. The number of water inlets 334 can be multiple, such as... Figure 6 As shown, multiple water inlets 334 are spaced apart along the length of the third contact portion 33.

[0064] In some embodiments, such as Figure 7 As shown, both the first sub-abutment portion 331 and the second sub-abutment portion 332 are plate-like structures extending along the length of the fixing frame 3. This allows for the formation of multiple longitudinal reinforcing ribs, which helps to improve the reinforcement effect on the support plate 34.

[0065] Among them, such as Figure 7 As shown, the water inlet 334 of the first sub-abutment part 331 and the water inlet 334 of the second sub-abutment part 332 can be staggered.

[0066] In some exemplary embodiments, such as Figure 6 As shown, the two ends of the fixed frame 3 along its length are provided with connecting parts 35, which are fixedly connected to the water receiving tray component 1.

[0067] The connection method between the connecting part 35 and the water receiving tray part 1 is not limited, such as fastener connection, snap connection, bonding, welding, etc.

[0068] In one embodiment, such as Figure 6 As shown, the connecting part 35 includes a connecting lug 351, and the connecting lug 351 is provided with a connecting hole 352. The water receiving tray component 1 is provided with a connecting post 12, as shown... Figure 9 As shown. Fasteners are inserted through the connecting hole 352 and fixedly connected to the connecting post 12.

[0069] like Figures 1 to 4 As shown, this application embodiment also provides an air conditioner 100, which includes the water tray structure of any of the above embodiments, and thus has all the above-mentioned beneficial effects, which will not be repeated here.

[0070] Among them, the type of air conditioner 100 is not limited. It can be the indoor unit of a split air conditioner (such as a wall-mounted air conditioner indoor unit, a cabinet air conditioner indoor unit, a ceiling-mounted air conditioner indoor unit, etc.), a split air conditioner unit (including indoor and outdoor units), or an integrated air conditioner.

[0071] In some embodiments, such as Figures 1 to 4 As shown, air conditioner 100 is a wall-mounted indoor unit. The wall-mounted indoor unit includes a casing 4, which has an air inlet and an air outlet connected to the air duct 8. An air guide plate 7 is located at the air outlet. The casing 4 houses components such as a heat exchanger 5 and a fan. A water tray assembly 1 forms the chassis, as shown... Figures 9 to 11 As shown, an air duct 8 is provided in the lower middle part of the chassis, and the impeller 6 of the fan is located in the air duct 8. A water receiving tank 11 is provided at the front of the chassis, and an antibacterial and anti-mildew sheet 2 is provided in the water receiving tank 11. The antibacterial and anti-mildew sheet 2 is fixed in the water receiving tank 11 by a fixing bracket 3.
