Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a cabinet-type air conditioner indoor unit. Background Technology

[0002] With the development of science and technology, the number of air conditioners is constantly increasing, and their functions are becoming more and more diverse. Existing air conditioners are usually equipped with air inlets that have filters, which need to be regularly removed and cleaned by users or maintenance personnel to ensure the normal operation of the air conditioner and the cleanliness of the indoor air, thus guaranteeing a good user experience.

[0003] Currently, in existing technologies, some column-type floor-standing air conditioner indoor units use a method where the disassembly cover and filter are connected, and both are pulled out together when disassembly is needed. However, because the filter and disassembly cover are connected together, the positioning of the disassembly cover and filter disassembly port can be inaccurate, affecting the stability of the connection at the disassembly port, and even causing the disassembly cover to fail to close properly. Some square-type air conditioner indoor units directly fasten the disassembly cover to the disassembly port using clips or screws, without connecting the filter and disassembly cover together. While this ensures the stability of the connection between the disassembly cover and the disassembly port, when removing the filter, the disassembly cover needs to be removed and placed somewhere, the filter removed and cleaned, and then the disassembly cover reattached to the disassembly port. This affects the efficiency of filter installation and removal, and may even lead to the disassembly cover being misplaced when it needs to be reattached, further reducing the efficiency of filter installation and removal.

[0057] In the description of this embodiment, the terms "this embodiment," "an alternative embodiment," "implementation," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0058] The following is combined Figures 1 to 8 This embodiment of the cabinet-type air conditioner indoor unit will be described in detail. Among them, Figure 7 The structure of the front cover of the housing is illustrated in detail.

[0059] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the indoor unit of the cabinet air conditioner may include a housing 100, a filter screen 200, a filter screen removal port 300, and a removal cover 400.

[0060] An air inlet 110 is provided on the housing 100, and an air inlet grille 120 is provided at the air inlet 110.

[0061] The filter screen 200 is located inside the air inlet grille 120 and is used to filter the airflow flowing into the air inlet 110.

[0062] The filter screen removal port 300 is provided on the housing 100 adjacent to the air inlet grille 120. The filter screen removal port 300 is used to allow the filter screen 200 to be installed on the inside of the air inlet grille 120 and removed from the inside of the air inlet grille 120 to the outside of the housing 100.

[0063] One end of the disassembly cover 400 is rotatably connected to the filter screen disassembly port 300. The disassembly cover 400 is used to open and close the filter screen disassembly port 300. The other end of the disassembly cover 400 is provided with a cover plate engaging structure 410. The filter screen disassembly port 300 is provided with a disassembly engaging structure 310 at a position corresponding to the cover plate engaging structure 410. The cover plate engaging structure 410 is engaged with the disassembly engaging structure 310.

[0064] In this embodiment of the cabinet-type air conditioner indoor unit, one end of its disassembly cover 400 can be rotatably connected to the filter screen disassembly port 300. Therefore, when the user or maintenance personnel disassemble the filter screen 200, they can open the filter screen disassembly port 300 without removing the disassembly cover 400 from the filter screen disassembly port 300, thus achieving quick disassembly of the filter screen 200. Furthermore, when it is time to reassemble the filter screen 200, there will be no situation where the disassembly cover 400 cannot be found. Furthermore, the other end of the disassembly cover 400 is provided with a cover plate engaging structure 410. The disassembly engaging structure 310 is connected to the cover plate engaging structure 410 at the filter screen disassembly port 300. Since the rotational connection between the disassembly cover 400 and the housing 100 at the filter screen disassembly port 300 can limit the relative positional relationship between the cover plate engaging structure 410 and the disassembly engaging structure 310 when the disassembly cover 400 is closed, and the engaging connection between the disassembly engaging structure 310 and the cover plate engaging structure 410 is not affected by the installation of the filter screen 200, the cover plate engaging structure 410 can be quickly and accurately engaged with the disassembly engaging structure 310, and the disassembly cover 400 can be quickly and accurately fastened onto the filter screen disassembly port 300. Therefore, the cabinet air conditioner indoor unit of this embodiment can ensure the connection stability between the disassembly cover 400 and the filter screen disassembly port 300, and improve the disassembly and assembly efficiency of the filter screen 200.

[0065] Reference Figure 1 and Figure 2 In this embodiment, at least one of the left and right sides of the housing 100 is provided with an air inlet 110 and a filter removal port 300.

[0066] It should be understood that the indoor unit of a cabinet air conditioner is usually quite large, so users will install it in a corner of the wall. The air inlet 110 and the filter removal port 300 are then located on the side of the casing 100. This ensures smooth air intake for the indoor unit and makes it easy to remove the filter 200.

[0067] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the disassembly cover 400 may be provided with a hinge shaft 420 for limiting its rotation. The hinge shaft 420 extends in the vertical direction. A hinge hole 320 is provided on the side wall of the filter screen disassembly port 300 at the position corresponding to the hinge shaft 420. The hinge shaft 420 is rotatably connected to the hinge hole 320.

[0068] It is understandable that, through the cooperation of the hinge shaft 420 and the hinge hole 320, the disassembly cover 400 can be rotatably connected to the filter screen disassembly port 300.

[0069] In an alternative embodiment, the disassembly cover 400 can be rotatably connected to the filter removal port 300 by connecting the disassembly cover 400 and the housing 100 at the adjacent filter removal port 300 via a hinge structure. Alternatively, the disassembly cover 400 and the housing 100 at the adjacent filter removal port 300 can be rotatably connected by a flexible (or elastic) connector.

[0070] Reference Figure 1 , Figure 2 and Figure 5 In this embodiment, the disassembly cover 400 may include a first end 430 and a second end 440 disposed opposite to each other, as well as a third end 450 and a fourth end 460 disposed opposite to each other. The first end 430 is disposed at the rear end of the filter screen disassembly port 300, the third end 450 is disposed upward, and the fourth end 460 is disposed downward.

[0071] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the hinge hole 320 may include a top shaft hole 321 and a bottom shaft hole 322. Furthermore, the hinge shaft 420 includes an upper hinge shaft section 421 and a lower hinge shaft section 422.

[0072] The top shaft hole 321 is opened on the top side wall of the filter screen disassembly port 300, and the top shaft hole 321 is located near the rear end of the filter screen disassembly port 300.

[0073] The bottom shaft hole 322 is opened on the bottom side wall of the filter screen disassembly port 300, and the bottom shaft hole 322 is located near the rear end of the filter screen disassembly port 300.

[0074] The upper hinge shaft section 421 is disposed on the third end 450 and is disposed close to the first end 430. The upper hinge shaft section 421 is rotatably connected to the top shaft hole 321.

[0075] The lower hinge shaft section 422 is coaxially arranged with the upper hinge shaft section 421. The lower hinge shaft section 422 is located on the fourth end 460 and is located close to the first end 430. The lower hinge shaft section 422 is rotatably connected to the bottom shaft hole 322.

[0076] It is understood that by setting the hinge shaft 420 as the upper hinge shaft segment 421 and the lower hinge shaft segment 422 as defined in this embodiment, and setting the hinge hole 320 as the top shaft hole 321 and the bottom shaft hole 322, the disassembly cover 400 can be rotatably connected to the filter screen disassembly port 300.

[0077] In an alternative embodiment, the hinge hole 320 includes a top shaft hole 321 and a bottom shaft hole 322. The top shaft hole 321 is formed on the top sidewall of the filter screen removal port 300 and is located near the rear end of the filter screen removal port 300.

[0078] The bottom shaft hole 322 is opened on the bottom side wall of the filter screen disassembly port 300, and the bottom shaft hole 322 is located near the rear end of the filter screen disassembly port 300.

[0079] Furthermore, the hinge shaft 420 can be configured to extend in the vertical direction, with the top end of the hinge shaft 420 extending out of the third end 450 of the disassembly cover 400, the bottom end of the hinge shaft 420 extending out of the fourth end of the disassembly cover 400, and the hinge shaft 420 being disposed at the first end 430.

[0080] It is understandable that by setting the hinge shaft 420 as a whole shaft that extends from the top end 450 of the disassembly cover 400 to the bottom end of the disassembly cover 400, and setting the hinge hole 320 as the top shaft hole 321 and the bottom shaft hole 322, with the upper and lower ends of the hinge shaft 420 connected to the top shaft hole 321 and the bottom shaft hole 322 respectively, the disassembly cover 400 can be rotatably connected to the filter screen disassembly port 300.

[0081] In another alternative embodiment, the hinge hole 320 includes a top shaft hole 321 and a bottom shaft hole 322. The top shaft hole 321 is formed on the top sidewall of the filter screen removal port 300 and is located near the rear end of the filter screen removal port 300.

[0082] The bottom shaft hole 322 is opened on the bottom side wall of the filter screen disassembly port 300, and the bottom shaft hole 322 is located near the rear end of the filter screen disassembly port 300.

[0083] Furthermore, the first end 430 of the disassembly cover 400 is provided with a hinge shaft through hole extending in the vertical direction. The hinge shaft 420 can be configured to extend in the vertical direction and pass through the hinge shaft through hole. The top end of the hinge shaft 420 extends out of the third end 450 of the disassembly cover 400, and the bottom end of the hinge shaft 420 extends out of the fourth end of the disassembly cover 400.

[0084] It is understandable that by configuring the hinge shaft 420 as a shaft that passes through and connects to the hinge shaft through hole, with its top end extending out of the third end 450 of the disassembly cover 400 and its bottom end extending out of the fourth end of the disassembly cover 400, and configuring the hinge hole 320 as a top shaft hole 321 and a bottom shaft hole 322, with the upper and lower ends of the hinge shaft 420 connected to the top shaft hole 321 and the bottom shaft hole 322 respectively, the disassembly cover 400 can be rotatably connected to the filter screen disassembly port 300. Furthermore, since the disassembly cover 400 can rotate relative to the hinge shaft 420, the smoothness of opening and closing the filter screen disassembly port 300 can be further ensured.

[0085] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the cover plate engaging structure 410 may include an elastic hook 411. Disassembling the engaging structure 310 may include disassembling the limiting plate 311.

[0086] A resilient hook 411 is connected to the second end 440, and the resilient hook 411 extends inward toward the inside of the removal cover 400. Furthermore,

[0087] The disassembly limiting plate 311 is located at the front end of the filter screen disassembly port 300 and extends toward the rear end of the filter screen disassembly port 300. The elastic hook 411 is hooked onto the inner side of the disassembly limiting plate 311 to restrict the disassembly cover 400 from rotating outward to open the filter screen disassembly port 300.

[0088] It is understood that the cover plate engaging structure 410 can be defined as the elastic hook 411 of this embodiment, and the disassembly engaging structure 310 can be defined as the disassembly limiting plate 311 of this embodiment. Therefore, the cover plate engaging structure 410 can be engaged with the disassembly engaging structure 310, and the other end of the disassembly cover 400 can be engaged with the filter screen disassembly port 300. Furthermore, the cooperation between the elastic hook 411 and the disassembly limiting plate 311 with the hinge shaft 420 and the hinge hole 320 can ensure the connection stability between the disassembly cover 400 and the filter screen disassembly port 300, improve the disassembly and assembly efficiency of the filter screen 200, and further ensure the connection stability of the disassembly cover 400 when it is fastened to the filter screen disassembly port 300.

[0089] In an alternative embodiment, the cover plate engaging structure 410 may include a cover plate removal groove, and the disassembly engaging structure 310 may include a disassembly limiting protrusion.

[0090] The cover plate removal groove is opened on the end face of the second end 440.

[0091] The disassembly limiting protrusion is connected to the front end of the filter screen disassembly port 300, and the disassembly limiting protrusion extends toward the rear end of the filter screen disassembly port 300. When the disassembly cover 400 is fastened to the filter screen disassembly port 300, the disassembly limiting protrusion is embedded in the disassembly groove of the cover plate.

[0092] It is understood that the cover plate engaging structure 410 can be defined as the cover plate disassembly groove of this embodiment, and the disassembly engaging structure 310 can be defined as the disassembly limiting protrusion of this embodiment. Therefore, the cover plate engaging structure 410 can be engaged with the disassembly engaging structure 310, and the other end of the disassembly cover 400 can be engaged with the filter screen disassembly port 300. Furthermore, the cooperation between the disassembly limiting protrusion and the cover plate disassembly groove with the hinge shaft 420 and the hinge hole 320 can ensure the connection stability between the disassembly cover 400 and the filter screen disassembly port 300, improve the disassembly and assembly efficiency of the filter screen 200, and further ensure the connection stability of the disassembly cover 400 when it is fastened to the filter screen disassembly port 300.

[0093] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the cover plate engaging structure 410 further includes an elastically bent connector 412.

[0094] The flexible bending connector 412 is connected between the second end 440 and the flexible hook 411, and an elastic gap 413 is provided between the disassembly cover 400 and the flexible hook 411 in the direction where the first end 430 and the second end 440 are located.

[0095] Understandably, the flexible bending connector 412 ensures the appropriate elastic force of the elastic hook 411, guaranteeing smooth contact between the elastic hook 411 and the disassembly limiting plate 311 during the closing and opening of the filter disassembly port 300 of the disassembly cover 400. Specifically, during the closing and opening of the filter disassembly port 300, the flexible bending connector 412 can be compressed in the direction of the first end 430 and the second end 440, allowing the elastic hook 411 to smoothly engage with and disengage from the disassembly limiting plate 311. Furthermore, after the disassembly cover 400 closes the filter disassembly port 300, the flexible bending connector 412 maintains the engagement between the elastic hook 411 and the disassembly limiting plate 311, thereby ensuring the connection stability between the disassembly cover 400 and the filter disassembly port 300 after the disassembly cover 400 closes the filter disassembly port 300.

[0096] Furthermore, the length L of the elastic gap 413 in the direction of the first end 430 and the second end 440 can be 10mm to 20mm, and preferably 15mm, to further ensure that the elastic hook 411 can smoothly engage with the disassembly limiting plate 311 and smoothly disengage from the disassembly limiting plate 311. Moreover, setting the elastic gap 413 to 10mm to 20mm, and preferably 15mm, can match the thickness of an adult's finger. Therefore, in the following embodiments, after the cover limiting part 414 is pushed backward by the user or maintenance personnel, a space to accommodate the user's or maintenance personnel's fingers can appear in front of the cover limiting part 414, facilitating the operation of the user or maintenance personnel and improving the efficiency of the user or maintenance personnel in opening the disassembly cover 400.

[0097] Reference Figure 2 , Figure 5 and Figure 6 In this embodiment, the head of the elastic hook 411 is disposed towards the inside of the disassembly cover 400, and the tail of the elastic hook 411 is disposed towards the outside of the disassembly cover 400.

[0098] Reference Figure 2 , Figure 5 and Figure 6 In this embodiment, the elastic bending connector 412 may include an inward connecting plate 4121 and an outward connecting plate 4122.

[0099] One end of the inward connecting plate 4121 is connected to the second end 440, and the other end of the inward connecting plate 4121 extends into the inside of the disassembly cover 400.

[0100] One end of the outward connecting plate 4122 is connected to the inward connecting plate 4121, and the other end of the outward connecting plate 4122 extends outward to the outside of the disassembly limiting plate 311 and is connected to the head of the elastic hook 411. The elastic gap 413 is located between the inward connecting plate 4121 and the outward connecting plate 4122 in the direction of the first end 430 and the second end 440.

[0101] It is understood that the elastic bending connector 412 can be specifically configured as the inward connecting plate 4121 and the outward connecting plate 4122 as defined in this embodiment, so as to enable the elastic bending connector 412 to achieve the effect of ensuring the appropriate elastic force of the elastic hook 411.

[0102] In an alternative embodiment, the resilient bending connector 412 may include an inward connecting plate 4121.

[0103] One end of the inward connecting plate 4121 is connected to the second end 440, and the other end of the inward connecting plate 4121 extends toward the inside of the disassembly cover 400. In the direction where the first end 430 and the second end 440 are located, the inward connecting plate 4121 is inclined away from the second end 440.

[0104] The elastic gap 413 is located between the inward connecting plate 4121 and the disassembly cover 400 in the direction of the first end 430 and the second end 440.

[0105] It is understood that the elastic bending connector 412 can be specifically configured as the inward connecting plate 4121 defined in this embodiment, so as to similarly enable the elastic bending connector 412 to achieve the effect of ensuring the appropriate elastic force of the elastic hook 411.

[0106] Reference Figure 2 and Figure 5 In this embodiment, the second end 440 of the disassembly cover 400 is provided with a bending clearance notch 470, and the elastic bending connector 412 and the elastic hook 411 are provided at the bending clearance notch 470.

[0107] Understandably, the setting of the bending avoidance notch 470 can prevent the cover plate locking structure 410 (such as the elastic bending connector 412) from being positioned on the outside of the disassembly cover 400 in the direction of the first end 430 and the second end 440. This ensures that the disassembly cover 400 can open or close the filter screen disassembly port 300 normally, while the disassembly cover 400 can cover the filter screen disassembly port 300 to the maximum extent, ensuring the relative sealing between the disassembly cover 400 and the filter screen disassembly port 300, and ensuring the filtration effect of the filter screen 200.

[0108] Reference Figure 2 , Figure 5 and Figure 6In this embodiment, the cover plate engaging structure 410 also includes an engaging limiting part 414.

[0109] The cover limiting part 414 is connected to the tail of the elastic hook 411, and a locking limiting groove 415 for accommodating the disassembly limiting plate 311 is formed between the cover limiting part 414 and the head of the elastic hook 411. The cover limiting part 414 abuts against the outer side of the disassembly limiting plate 311 to restrict the disassembly cover 400 from continuing to rotate into the filter screen disassembly port 300 after it is closed.

[0110] Understandably, the closing limiting part 414 ensures that after the disassembly cover 400 is fastened to the filter screen disassembly port 300, the outer surface of the disassembly cover 400 and the surface of the housing 100 are on the same plane, thus ensuring the aesthetic appearance of the housing 100. Simultaneously, in conjunction with the engaging limiting groove 415, it further ensures the stability of the disassembly cover 400 fastened to the filter screen disassembly port 300. Furthermore, the closing limiting part 414 can be pushed backward to disengage the elastic hook 411 from the disassembly limiting plate 311, facilitating the user or maintenance personnel to open the disassembly cover 400 and improving the efficiency of disassembling the filter screen 200.

[0111] Alternatively, the cover limiting part 414 can be a block structure extending in the vertical direction.

[0112] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the disassembly and engagement structure 310 also includes a disassembly clearance port 312.

[0113] The disassembly clearance port 312 is provided corresponding to the elastic bending connector 412, and the disassembly clearance port 312 is located behind the disassembly limiting plate 311. The disassembly clearance port 312 is used to accommodate the bending connector.

[0114] Understandably, the housing 100 has a limiting wall plate 130 facing the disassembly cover 400 at the front end of the filter screen disassembly port 300 to further restrict the disassembly cover 400 from continuing to rotate inward into the filter screen disassembly port 300 after it is closed. Furthermore, a disassembly clearance opening 312 is provided on the limiting wall plate 130 to prevent the limiting wall plate 130 from abutting against the elastic bending connector 412, thus preventing the disassembly cover 400 from affecting the closure of the filter screen disassembly port 300. This allows the disassembly cover 400 to be fully closed, further ensuring the relative sealing between the disassembly cover 400 and the filter screen disassembly port 300, guaranteeing the filtration effect of the filter screen 200, and further ensuring the aesthetic appearance of the housing 100.

[0115] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment, the filter screen removal port 300 is located above the air inlet 110; and the top of the filter screen 200 is connected to a handle 210, and the handle 210 has a handle groove 211 extending in the front-back direction, and the handle 210 is located inside the filter screen removal port 300.

[0116] Understandably, the design of the handle groove 211 makes it easy for users or maintenance personnel to pull out the filter screen 200 with the screen facing upwards, facilitating disassembly.

[0117] Reference Figure 7 and Figure 8 In this embodiment, filter screen grooves 121 extending in the vertical direction are provided at the front and rear ends of the inner side of the air inlet grille 120, and the filter screen 200 can be slidably disposed in the filter screen groove 121 in the vertical direction to ensure that the filter screen 200 can be smoothly installed into the inner side of the air inlet grille 120, or smoothly removed from the filter screen removal port 300.

[0118] Reference Figure 7 and Figure 8 In this embodiment, an installation stop 140 extending in the front-rear direction is provided on the inner side of the air inlet grille 120. The installation stop 140 is located below the filter screen removal port 300 and is adjacent to the filter screen removal port 300. An installation limiting removal port 141 communicating with the top of the filter screen slide groove 121 is provided between the installation stop 140 and the air inlet grille 120.

[0119] It is understandable that an installation limiting and disassembly opening 141 is formed between the mounting baffle 140 and the inner side of the air inlet grille 120. This can prevent the filter screen 200 from extending into the deep interior of the housing 100 when the user or maintenance personnel install the filter screen 200 into the inner side of the air inlet grille 120. This makes it easier for the user or maintenance personnel to insert the filter screen 200 into the filter screen slide groove 121, facilitating the disassembly operation of the user or maintenance personnel.

[0120] Reference Figures 1 to 8 In this embodiment, when the user or maintenance personnel need to disassemble and clean the filter screen 200, they can first push the cover limiting part 414 backward to disengage the elastic hook 411 from the disassembly limiting plate 311, thus opening the filter screen disassembly port 300. Next, the filter screen 200 can be pulled upward using the handle 210, and after cleaning, it can be reinstalled from the filter screen disassembly port 300 back into the air inlet grille 120. Finally, the disassembly cover 400 is fastened to the filter screen disassembly port 300, so that the cover locking structure 410 and the disassembly locking structure 310 are engaged, thus closing the filter screen disassembly port 300.

[0121] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
