Description

Technical Field

[0001] This application belongs to the field of air conditioning technology, and in particular relates to an air conditioning unit. Background Technology

[0002] When an air conditioner is working, the internal heat exchanger exchanges heat with the indoor air, producing condensation on its surface. Currently, most floor-standing air conditioners have a drip tray located below the heat exchanger to collect this condensation. However, over time, the drip tray is prone to bacterial growth, mold, and dust accumulation, which can clog the drain outlet and lead to leaks, causing inconvenience and a poor user experience.

[0003] However, with existing air conditioner cabinet units, if users want to disassemble and clean the drain pan, they need to first remove the external panel and internal sealing plate of the air conditioner to expose the drain pan before it can be removed. This is a lot of work and time-consuming. Utility Model Content

[0043] This application provides an air conditioner cabinet unit as an example; please refer to [link to example]. Figures 1-3 , Figure 1 This is a structural schematic diagram of the air conditioner cabinet unit provided in the embodiments of this application. Figure 2 This is a structural schematic diagram of another state of the air conditioner cabinet unit provided in the embodiments of this application. Figure 3 for Figure 1 The exploded view of the air conditioner unit shown is shown. The air conditioner unit 10 includes a housing 100, an evaporator assembly 200, and a heat insulation panel 300.

[0044] The outer casing 100 includes a rear casing 110 and a panel 120. The rear casing 110 forms a receiving space 112 with a forward opening 111. The panel 120 is disposed on the front side of the rear casing 110 for opening or closing the opening 111. The evaporation assembly 200 is disposed in the receiving space 112 and includes an evaporator (not shown in the figure) and a water tray 210 disposed below the evaporator. The heat insulation plate 300 is disposed between the panel 120 and the evaporation assembly 200 for heat insulation. The heat insulation plate 300 includes a fixing part 310 and a quick-release part 320. The fixing part 310 is fixedly installed in the receiving space 112, and the quick-release part 320 is detachably connected to the bottom of the fixing part 310. When the quick-release part 320 is removed, the water tray 210 is suitable to be exposed to the outside through the opening 111.

[0045] It should be noted that the drip tray 210 is detachably installed in the receiving space 112, allowing for disassembly and cleaning. The drip tray 210 is positioned below the evaporator to collect condensate dripping from the evaporator surface. The heat insulation plate 300, installed between the panel 120 and the evaporator assembly 200, provides insulation for the evaporator assembly 200, reducing heat exchange between the external environment and the evaporator assembly 200, thereby reducing condensation on the evaporator assembly 200 and improving its operating efficiency.

[0046] In practical applications, when a user disassembles and washes the water tray 210, they must first move the panel 120 to open the opening 111. Then, by quickly removing the quick-release part 320 from the fixed part 310, the water tray 210 is exposed to the outside through the opening 111, making it easy to remove the water tray 210 for cleaning. After the user has finished cleaning the water tray 210, the water tray 210 is reinstalled in its original position, and then the quick-release part 320 and the panel 120 are reinstalled in their original positions in sequence, which is very convenient.

[0047] The panel 120 may be rotatably or slidably connected to the rear housing 110. For example, the panel 120 may be hinged to one side of the rear housing 110 and adapted to rotatably open or close the opening 111. The panel 120 may also be detachably connected by means of snaps, screws, or magnets. The evaporator may be, for example, flat and inclined in the receiving space 112. The evaporator may also be placed vertically or horizontally, and its shape is not limited to flat.

[0048] The fixing part 310 and / or the quick-release part 320 may include an insulation layer 340, which is made of sponge. For example, the fixing part 310 and / or the quick-release part 320 includes a board body and a sponge layer adhered to the surface of the board body. The sponge layer is made of polyethylene sponge with a thickness of 5-10mm. Polyethylene sponge is a high-density sponge that can provide good insulation.

[0049] Optionally, a mounting frame (not shown in the figure) is also provided in the receiving space 112 of the rear shell 110, and the evaporation assembly 200 is mounted on the mounting frame. The water tray 210 can be slidably connected to the mounting frame, suitable for sliding out or into the receiving space 112 through the opening 111. When the water tray 210 slides out of the receiving space 112, it facilitates cleaning by the user from the outside. For example, slide rails are provided on the left and right sides of the water tray 210, and correspondingly, the mounting frame is provided with a sliding groove extending in the front-back direction. The slide rails and the sliding grooves cooperate to allow the water tray 210 to be slidably connected to the mounting frame. In other optional embodiments, the water tray 210 can also be detachably connected to the mounting frame by means of clips, screws, or magnets.

[0050] The air conditioner cabinet unit 10 provided in this application embodiment, on the one hand, uses a heat insulation plate 300 to insulate the evaporator component 200, which reduces condensation on the evaporator component 200 and improves the working efficiency of the evaporator; on the other hand, the heat insulation plate 300 is configured with a fixed part 310 and a quick-release part 320. By quickly removing the quick-release part 320 from the fixed part 310, the water tray 210 can be exposed to the outside through the opening 111, making it convenient for users to disassemble and clean the water tray 210, thus improving the cleanliness of the air conditioner cabinet unit 10 itself and the air outlet. Compared with the amount of disassembly required when cleaning the water tray 210 in traditional cabinet units, the air conditioner cabinet unit 10 of this application greatly simplifies the disassembly work and improves the convenience for users to clean the water tray 210.

[0051] In some embodiments, please refer to Figures 4-5 , Figure 4 This is a schematic diagram of the structure of the heat insulation board provided in the embodiments of this application. Figure 5 This is a schematic diagram of the structure of the heat insulation board provided in another state according to an embodiment of this application. The lower edge of the fixing part 310 is bent forward to form a folded edge 311, and the upper end of the quick-release part 320 is recessed to form an insertion groove 321. The insertion groove 321 is suitable for the folded edge 311 to be inserted, so that the quick-release part 320 and the fixing part 310 can be detachably connected. In this way, by inserting or separating the folded edge 311 from the insertion groove 321, the quick-release part 320 and the fixing part 310 can be quickly assembled and disassembled, which is very convenient. For example, the insertion groove 321 is a U-shaped groove with a bending angle of 90°, and the T-shaped feature is the sum of the plate thickness and 2mm.

[0052] Optionally, please refer to Figure 6 , Figure 6 for Figure 4 Enlarged view of area A. The air conditioner unit 10 also includes a first sealing element 400, which is sealed between the folded edge 311 and the inner wall of the insertion groove 321. This seals the gap between the folded edge 311 and the insertion groove 321, preventing moisture leakage and improving the insulation effect of the heat insulation plate 300 on the evaporator assembly 200. Preferably, the first sealing element 400 is strip-shaped and wraps around the three upper, lower, and front walls of the folded edge 311. Preferably, the first sealing element 400 is made of sponge material and is interference-fitted with the inner wall of the folded edge 311 and the insertion groove 321. For example, the first sealing element 400 is made of 3mm thick polyurethane sponge with a compression ratio of 60-70%. This ensures that the first sealing element 400 has good insulation and sealing effects.

[0053] Optionally, the upper edge of the quick-release part 320 is bent and overlaps with the outer wall of the insertion slot 321. This prevents the user from being cut when touching the edge.

[0054] In some embodiments, please refer to Figures 7-8 , Figure 7 This is a schematic diagram of the water receiving tray provided in an embodiment of this application. Figure 8 This is a schematic diagram of the connection between the heat insulation plate and the water receiving tray provided in this embodiment. The air conditioner unit 10 also includes a limiting buckle 500, which is connected to the outer wall of the water receiving tray 210 and forms a limiting groove 510 with the slot facing upward. The lower end of the quick-release part 320 is inserted into the limiting groove 510. In this way, by limiting the lower end of the quick-release part 320 in the front-back direction through the limiting groove 510, the stability of the quick-release part 320 installed on the fixed part 310 can be further improved, preventing the quick-release part 320 from detaching from the fixed part 310 due to bumps.

[0055] In practical applications, when installing the quick-release part 320, the user must first insert the lower end of the quick-release part 320 into the limiting groove 510, and then mate the upper insertion groove 321 with the folded edge 311 to complete the quick-release part 320's quick-release installation. When disassembling the quick-release part 320, the insertion groove 321 is first separated from the folded edge 311, and then the lower end of the quick-release part 320 is pulled out from the limiting groove 510 to complete the quick-release part 320's quick-release.

[0056] Optionally, the limiting buckle 500 is L-shaped, with one end connected to the front side wall of the water receiving tray 210, and the other end spaced opposite to the front side wall of the water receiving tray 210. The limiting buckle 500 and the front side wall of the water receiving tray 210 form a limiting groove 510. The limiting groove 510 can be integrally formed with the water receiving tray 210, or it can be detachably connected to the water receiving tray 210. The number of limiting buckles 500 can be multiple, for example, three, and the multiple limiting buckles 500 are spaced apart on the front side wall of the water receiving tray 210, with the spacing between each pair of adjacent limiting buckles 500 being, for example, the same. Preferably, the end of the limiting buckle 500 away from the water receiving tray 210 is provided with a guide slope 520. The guide slope 520 is used to guide the quick-release part 320 when it is inserted into the limiting groove 510, and the elastic buckle is elastic to facilitate the quick installation of the quick-release part 320. Preferably, a reinforcing rib 530 is provided on the side surface of the elastic buckle opposite to the limiting groove 510. This improves the structural strength of the limiting buckle 500 and ensures the feasibility of its function.

[0057] In some embodiments, along the left-right direction, at least one side of the quick-release part 320 is provided with a first connecting part 330, and the first connecting part 330 is provided with a first through hole 331; the rear shell 110 includes a second connecting part 113 disposed opposite to the first connecting part 330, and the second connecting part 113 is provided with a second through hole 114; the air conditioner cabinet 10 also includes a connecting pin 600, which is sequentially inserted into the first through hole 331 and the second through hole 114, and is detachably engaged with the hole wall of the first through hole 331 and the hole wall of the second through hole 114, so that the first connecting part 330 and the second connecting part 113 are fixedly connected. In this way, by detachably connecting the quick-release part 320 to the rear shell 110, the connecting pin 600 can further enhance the stability of the quick-release part 320 installed on the fixing part 310, and prevent the quick-release part 320 from detaching from the fixing part 310 due to bumps.

[0058] In practical applications, when installing the quick-release part 320, the user first inserts the lower end of the quick-release part 320 into the limiting groove 510, then mates the upper insertion groove 321 with the folded edge 311, and finally connects the connecting pin 600 to the first connecting part 330 and the second connecting part 113 to complete the quick-release part 320. When disassembling the quick-release part 320, the pin must first be removed from the first connecting part 330 and the second connecting part 113, then the insertion groove 321 and the folded edge 311 must be separated, and finally the lower end of the quick-release part 320 must be pulled out of the limiting groove 510 to complete the quick release of the quick-release part 320.

[0059] The connecting pin can be a locking screw or a locking resilient pin. For an example, please refer to [link to example]. Figures 9-10 , Figure 9 This is a schematic diagram of the connecting pin in its first state, as provided in an embodiment of this application. Figure 10 This is a schematic diagram of the connecting pin in the second state according to an embodiment of this application. The connecting pin 600 includes a first elastic part 610 and two pin parts 620 disposed at both ends of the first elastic part 610. The two pin parts 620 are disposed at a distance from each other and are used to pass through the first through hole 331 and the second through hole 114. Each pin part 620 is provided with a groove 621, which is adapted to engage with the hole wall of the first through hole 331 and the hole wall of the second through hole 114. The first elastic part 610 has a first state in which the two pin parts 620 are driven to move closer to each other under external force, and a second state in which the two pin parts 620 are driven to move away from each other based on elastic restoring force.

[0060] In practical applications, when the user disassembles the quick-release part 320, the user needs to apply pressure with their hand to make the elastic part present in the first state. At this time, the two pin parts 620 approach each other, causing the slot 621 to disengage from the hole wall of the first through hole 331 and the hole wall of the second through hole 114. The pin part 620 can move in the first through hole 331 and the second through hole 114, so that the user can pull the pin part 620 out of the first through hole 331 and the second through hole 114 to remove the pin from the first connecting part 330 and the second connecting part 113. When installing the quick-release part 320, the user needs to apply pressure to make the elastic part in the first state. After the two pin parts 620 are inserted into the first through hole 331 and the second through hole 114, the user stops applying force to the elastic part. The elastic part then enters the second state based on the elastic restoring force. At this time, the two pin parts 620 move away from each other, so that the slot 621 engages with the hole wall of the first through hole 331 and the hole wall of the second through hole 114 to connect the connecting pin 600 to the first connecting part 330 and the second connecting part 113.

[0061] Optionally, the connecting pin 600 further includes a second elastic portion 630 disposed between the two pin portions 620. When the two pin portions 620 approach each other, the second elastic portion 630 is compressed and deformed. When the second elastic portion 630 stops being subjected to external force, the two pin portions 620 will be driven away from each other based on the elastic restoring force. It can be understood that the second elastic portion 630 is adapted to assist the first elastic portion 610 in functioning, or to replace the first elastic portion 610 in functioning when the first elastic portion 610 fails. In this way, the functionality of the connecting pin 600 can be ensured. For example, the second elastic portion 630 includes two elastic arms, each elastic arm connected to a pin portion 620, and the two elastic arms are disposed opposite each other.

[0062] In some embodiments, the air conditioner unit 10 further includes a second seal 700, which is sealingly connected between the first connecting portion 330 and the second connecting portion 113. Preferably, the second seal 700 is made of sponge material and is interference-fitted with the first connecting portion 330 and the second connecting portion 113. For example, the second seal 700 is made of 3mm thick polyurethane sponge with a compression capacity of 60-70%. This ensures that the second seal 700 has a good sealing effect.

[0063] In some embodiments, one of the first connecting portion 330 and the second connecting portion 113 is provided with a positioning groove, and the other is provided with a positioning rib 115. The positioning rib 115 is used to limit the positioning in the positioning groove to achieve mutual positioning of the first connecting portion 330 and the second connecting portion 113. Thus, by achieving quick positioning of the first connecting portion 330 on the second connecting portion 113, it is beneficial to quickly install the quick-release part 320 on the rear cover 110. For example, as shown... Figure 3 As shown, a positioning groove 332 is provided on the first connecting part 330, and a positioning rib 115 is provided on the second connecting part 113.

[0064] Optionally, the rear cover 110 includes a back panel (not shown) disposed opposite to the front panel 120, and a side panel 116 that is bent and connected to the back panel and extends forward, wherein the front edge of the side panel 116 is bent to form a second connecting portion 113.

[0065] Optionally, in the left-right direction, at least one side of the fixing part 310 is provided with a third connecting part 312, which is fixedly connected to the second connecting part 113 by a fastener. The fastener can be a bolt, a resilient pin, or other fixing structure. Optionally, the second sealing member 700 extends between the second connecting part 113 and the third connecting part 312, for example, with an interference fit to both the second connecting part 113 and the third connecting part 312. The second connecting part 113 and the third connecting part 312 can also be positioned relative to each other during installation by providing a positioning structure; for details, refer to the positioning structure between the first connecting part 330 and the second connecting part 113 described above, which will not be repeated here.

[0066] The air conditioner cabinet unit 10 provided in this application embodiment, on the one hand, uses a heat insulation plate 300 to insulate the evaporator component 200, which reduces condensation on the evaporator component 200 and improves the working efficiency of the evaporator; on the other hand, the heat insulation plate 300 is configured with a fixed part 310 and a quick-release part 320. By quickly removing the quick-release part 320 from the fixed part 310, the water tray 210 can be exposed to the outside through the opening 111, making it convenient for users to disassemble and clean the water tray 210, thus improving the cleanliness of the air conditioner cabinet unit 10 itself and the air outlet. Compared with the amount of disassembly required when cleaning the water tray 210 in traditional cabinet units, the air conditioner cabinet unit 10 of this application greatly simplifies the disassembly work and improves the convenience for users to clean the water tray 210.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
