Description

Technical Field

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

[0002] As people's living standards improve, the number of air conditioners on the market is increasing. Furthermore, to meet user needs, air conditioners are becoming increasingly diverse in their functions. For example, some indoor units are equipped with fresh air systems to refresh the air in the indoor space, improving the user experience. The indoor unit has a heat exchange air inlet, which draws in ambient airflow to exchange heat with the indoor heat exchanger. To further enhance the user experience, air filters are typically installed at both the heat exchange air inlet and the fresh air inlet of the fresh air system to filter the ambient airflow that needs heat exchange and the incoming fresh air.

[0003] Currently, in existing technology, air filters are often transported as separate accessories during air conditioner delivery. However, installers may forget to install the air filter at the heat exchanger and fresh air inlets. This makes it difficult to guarantee the cleanliness of the airflow regulating the indoor environment, significantly impacting the user experience. Furthermore, during long-term use, the air filter element or screen needs replacement or cleaning. When users or repair personnel reinstall the air filter at the heat exchanger and fresh air inlets, improper installation is common, leading to air leakage and reduced purification efficiency, again diminishing the user experience.

The first direction and the second direction are perpendicular to each other in the wall surface of the wall panel.

[0025] Furthermore, the elastic limiting body includes:

[0026] A limiting base plate, one end of which is connected to the wall panel;

[0027] An elastic plate has one end connected to the end of a limiting base plate away from the wall panel, and the other end extending towards the wall panel.

[0054] In the description of this embodiment, the reference to terms such as "embodiment," "embodiment mode," etc., means that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is 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.

[0055] The following is combined with Figures 1 to 10 The indoor unit of the air conditioner in this embodiment will be described in detail below.

[0056] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the indoor unit of the air conditioner may include a housing 100, an air filter 300, a position detection component 400, and a position detection sensor 500.

[0057] The housing 100 has a filter element receiving space 200 inside, and the housing 100 has a filter element disassembly port 110 that communicates with the filter element receiving space 200.

[0058] The air filter element 300 is detachably disposed within the filter element receiving space 200 via the filter element disassembly port 110, and the air filter element 300 is used to filter the airflow in the filter element receiving space 200.

[0059] The detection component 400 is installed on the air filter 300.

[0060] The position detection sensor 500 is disposed on the wall panel 210 constituting the filter element receiving space 200, and the position detection sensor 500 is disposed opposite to the position detection element 400 when the air filter element 300 is installed in place.

[0061] Because the indoor unit of this embodiment has a positioning detection element 400 on the air filter 300 and a positioning detection sensor 500 on the wall panel 210 constituting the filter receiving space 200 for accommodating the air filter 300, and the positioning detection element 400 can be positioned opposite the positioning detection sensor 500 after the air filter 300 is installed in place, the positioning detection sensor 500 can detect the positioning detection element 400 after the air filter 300 is installed in place. This effectively avoids situations where the air filter 300 is forgotten to be installed or is not installed properly. Therefore, the indoor unit of this embodiment can ensure the cleanliness of the airflow regulating the indoor environment, guarantee the purification effect of the air filter 300, and improve the user experience.

[0062] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the air filter 300 includes a filter support frame 310 and a filter element 320.

[0063] The filter element support frame 310 is detachably installed in the filter element receiving space 200 via the filter element disassembly port 110.

[0064] The filter element 320 is disposed on the filter element support frame 310, and the filter element 320 is used to filter the airflow in the filter element 320 receiving space 200.

[0065] It is understandable that the filter element 320 can be a filter screen, filter cartridge, or other components. However, these components are all made of soft materials. Therefore, in order to ensure the effective filtration area of ​​the filter element 320 and to allow the filter element 320 to extend and be fixed, a filter element support can be provided, and the filter element 320 can be placed on the filter element support.

[0066] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the positioning detection element 400 is disposed on the side of the filter support frame 310 facing the wall panel 210. Furthermore,

[0067] A limiting installation structure 600 is provided at the position of the wall panel 210 corresponding to the position detection component 400, and the position detection sensor 500 is installed on the limiting installation structure 600.

[0068] It is understandable that when the air filter 300 is equipped with a filter support frame 310, the positioning detection element 400 can be set on the filter support frame 310. Through the setting of the limiting installation structure 600, the positioning detection sensor 500 can be installed on the wall panel 210 constituting the filter receiving space 200 corresponding to the positioning detection element 400. Therefore, the positioning detection sensor 500 can be set opposite to the positioning detection element 400 when the air filter 300 is installed in place.

[0069] Reference Figure 4 and Figure 5 In this embodiment, the positioning detection element 400 may include a magnet 410. The positioning detection sensor 500 may include a magnetic sensor 510.

[0070] It is understood that the position detection element 400 and the position detection sensor 500 can be configured as a magnet 410 and a magnetic sensor 510 respectively, so that the position detection sensor 500 can detect the position detection element 400 when the position detection element 400 is opposite to the position detection sensor 500, thereby determining that the air filter element 300 is disposed in the filter element receiving space 200 and that the air filter element 300 has been installed in place.

[0071] Reference Figure 4 , Figure 5 and Figure 6 In this embodiment, the magnet 410 can be embedded in the side of the filter support frame 310 facing the wall panel 210. Furthermore,

[0072] The magnetic sensor 510 is mounted on the limiting mounting structure 600, and both the magnetic sensor 510 and the limiting mounting structure 600 can be disposed on the outer surface of the wall panel 210.

[0073] Understandably, based on the magnetic induction principle of magnet 410 and magnetic sensor 510, when magnet 410 and magnetic sensor 510 are relative, magnetic sensor 510 can detect magnet 410 without contact or by being separated from it by components that do not affect its magnetism. Furthermore, magnet 410 can be embedded in the side of filter support frame 310 facing wall panel 210 to avoid interference between the positioning detection element 400 or magnet 410 and other components during the movement of air filter 300, thus ensuring the smooth installation of air filter 300 into filter receiving space 200. Moreover, both magnetic sensor 510 and limiting installation structure 600 can be located on the outer surface of wall panel 210 to prevent magnetic sensor 510 (or positioning detection sensor 500) and limiting installation structure 600 from interfering with the movement of air filter 300, similarly ensuring the smooth installation of air filter 300 into filter receiving space 200.

[0074] Reference Figure 4 and Figure 5 In this embodiment, the filter support frame 310 has a detection receiving groove 311 on the side facing the wall panel 210, the magnet 410 is embedded in the detection receiving groove 311, and the opening of the detection receiving groove 311 is provided with a detection limiting body 312 for restricting the magnet 410 from falling out of the detection receiving groove 311.

[0075] Understandably, the detection receiving groove 311 and the detection limiting body 312 can enable the magnet 410 to be embedded in the side of the filter support frame 310 facing the wall panel 210.

[0076] Reference Figure 4 and Figure 5In this embodiment, the magnet 410 can be clamped between the bottom of the detection receiving groove 311 and the detection limiting body 312 to ensure the stability of the magnet 410 embedded in the detection receiving groove 311, and to ensure the accuracy of the determination structure that the air filter 300 is configured in the filter receiving space 200 and that the air filter 300 has been installed in place, thereby further improving the user experience.

[0077] Reference Figure 4 and Figure 5 In this embodiment, the detection limiting body 312 and the groove wall of the detection receiving groove 311 are connected by multiple connecting ribs 313, so that the detection limiting body 312 can be set at the groove opening of the detection receiving groove 311.

[0078] Furthermore, connecting through holes are provided between the multiple connecting ribs 313.

[0079] In another embodiment of the position detection element 400 and the position detection sensor 500, the position detection sensor 500 may include a pressure sensor, and the position detection element 400 may include a protruding structure capable of pressing the pressure sensor.

[0080] When the position detection sensor 500 and the position detection element 400 are positioned opposite each other, the position detection element 400 can press against the position detection sensor 500; that is, the protruding structure can press against the pressure sensor, at which point the pressure sensor can detect the protruding structure. Furthermore, when the position detection sensor 500 is configured as a pressure sensor and the position detection element 400 is configured as a protruding structure, the position detection sensor 500 can also detect the position detection element 400 to determine that the air filter element 300 is positioned within the filter element receiving space 200 and that the air filter element 300 has been installed in place.

[0081] In another embodiment of the position detection element 400 and the position detection sensor 500, the position detection sensor 500 may include a photoelectric sensor, and the position detection element 400 may include a shield capable of blocking the light emitted by the photoelectric sensor.

[0082] When the position detection sensor 500 and the position detection element 400 are positioned opposite each other, that is, when the obstruction can block the light emitted by the photoelectric sensor, the photoelectric sensor can detect the obstruction. Furthermore, when the position detection sensor 500 is configured as a photoelectric sensor and the position detection element 400 is configured as an obstruction, the position detection sensor 500 can also detect the position detection element 400 to determine that the air filter 300 is positioned within the filter housing space 200 and that the air filter 300 has been installed in place.

[0083] Reference Figure 4 , Figure 6 and Figure 7 In this embodiment, the limiting installation structure 600 may include a limiting plate 610 and an elastic limiting body 620.

[0084] The limiting plate 610 is disposed on the wall panel 210, and the upper limit of the limiting plate 610 in the first direction is located at both ends of the positioning detection sensor 500.

[0085] The elastic limiting body 620 is disposed on the wall panel 210, and the elastic limiting body 620 is located at both ends of the position detection sensor 500 in the second direction, and the elastic limiting body 620 abuts against the side of the position detection sensor 500 facing away from the wall panel 210, so as to limit the position detection sensor 500 on the wall panel 210. The first direction and the second direction are perpendicular to each other in the wall surface of the wall panel 210.

[0086] Understandably, the limiting plate 610 and the elastic limiting body 620 can assemble the position sensor onto the wall panel 210 constituting the filter element receiving space 200, so that the limiting mounting structure 600 can install the position detection sensor 500 onto the wall panel 210 constituting the filter element receiving space 200. Furthermore, the limiting plate 610 and the elastic limiting body 620 can restrict the movement of the position detection sensor in the first and second directions, that is, restrict the movement of the position detection sensor along the plane containing the wall surface of the wall panel 210, ensuring the installation stability of the position detection sensor 500 on the wall panel 210 constituting the filter element receiving space 200.

[0087] Reference Figure 4 , Figure 6 and Figure 7 In this embodiment, the elastic limiting body 620 may include a limiting substrate 621 and an elastic plate 622.

[0088] One end of the limiting base plate 621 is connected to the wall plate 210.

[0089] One end of the elastic plate 622 is connected to the end of the limiting base plate 621 away from the wall plate 210, and the other end of the elastic plate 622 extends toward the wall plate 210. A positioning notch 6221 is provided at the end of the elastic plate 622 extending toward the wall plate 210. The positioning notch 6221 has a limiting surface 6222 facing the positioning detection sensor 500 in a second direction and a supporting surface 6223 facing the wall plate 210. Both the limiting surface 6222 and the supporting surface 6223 abut against the positioning detection sensor 500. Furthermore,

[0090] The limiting plate 610 has an outer edge plate 630 connected to both ends in the second direction. The outer edge plate 630 is disposed at both ends of the position detection sensor 500 in the second direction.

[0091] It is important to understand that the positioning notch 6221 ensures the stability of the contact between the elastic limiting body 620 and the position detection sensor 500 when the elastic limiting body 620 abuts against the position detection sensor 500, while simultaneously limiting the position detection sensor 500 in the second direction. Furthermore, the outer edge plate 630 further restricts the movement of the position detection sensor in the second direction, further ensuring the installation stability of the position detection sensor 500 on the wall plate 210 constituting the filter element receiving space 200.

[0092] In another embodiment of the limiting mounting structure 600, the limiting mounting structure 600 may be a screw post, and the position detection sensor 500 may be mounted to the wall panel 210 constituting the filter element receiving space 200 by means of a screw and screw post connection.

[0093] Reference Figure 1 In this embodiment, the indoor unit of the air conditioner can be a vertical indoor unit.

[0094] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 In one embodiment of this invention, the indoor unit of the air conditioner may further include a fresh air module 700 and a filter cover 800.

[0095] The fresh air module 700 is disposed inside the housing 100 and is located at the lower part of the housing 100. Similarly, the filter removal port 110 is also opened at the lower part of the housing 100.

[0096] The filter cover 800 is fastened to the fresh air inlet 710 of the fresh air module 700, and a filter element receiving space 200 is formed between the filter cover 800 and the fresh air module 700. A fresh air disassembly port 810 is provided on the filter cover 800 at the position corresponding to the filter element disassembly port 110. The air filter 300 is detachably installed in the filter element receiving space 200 by the filter element disassembly port 110 and the fresh air disassembly port 810.

[0097] It is understandable that the air filter 300 can be installed at the fresh air inlet of the fresh air module 700 and filter the fresh air flow drawn in by the fresh air module 700 from the outdoor space. In this case, the filter 320 can be a pre-filter.

[0098] In addition, the fresh air module 700 may include a fresh air fan, which is generally configured as a centrifugal fan. The centrifugal fan may include a volute 720 and a fan disposed in the volute 720, and the fresh air inlet 710 is opened at the axial center of the volute 720.

[0099] Furthermore, the cooperation between the filter cover 800 and the volute 720 of the fresh air module 700 can provide a filter housing space 200 for installing the air filter 300.

[0100] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 In this embodiment, the filter cover 800 includes a filter base plate 820 located below the filter element receiving space 200, and the wall panel 210 is the filter base plate 820.

[0101] Understandably, since the air filter element 300 has a certain weight, when it is assembled into the filter element receiving space 200, the distance between the air filter element 300 and the filter base plate 820 is generally the closest compared to other components of the air filter element 300 and the filter cover 800. Therefore, placing the position detection sensor 500 and the limiting installation structure 600 on the filter base plate 820 can effectively ensure the accuracy of the position detection sensor 500 in detecting the position detection element 400, ensure the accuracy of detecting whether the air filter element 300 is installed in place, and ensure the user's experience.

[0102] Reference Figure 4 and Figure 6 In this embodiment, the position detection sensor 500 is installed adjacent to the fresh air disassembly port 810.

[0103] Understandably, since the fresh air disassembly port 810 is closer to the outer side of the housing 100, placing the position detection sensor 500 adjacent to the fresh air disassembly port 810 facilitates the maintenance and repair of the position detection sensor 500. Furthermore, since other functional components of the air conditioner may be located inside the housing 100 compared to areas farther from the fresh air disassembly port 810, the area adjacent to the fresh air disassembly port 810 has fewer functional components. Therefore, placing the position detection sensor 500 adjacent to the fresh air disassembly port 810 simplifies the maintenance and repair of the position detection sensor 500.

[0104] Reference Figure 1 , Figure 3 , Figure 4 and Figure 8 In this embodiment, the air filter 300 is provided with a disassembly cover 330 for sealing the filter disassembly port 110 on the filter support frame 310, and the position detection member 400 is provided adjacent to the disassembly cover 330.

[0105] Understandably, the disassembly cover 330 can relatively seal the filter element disassembly port 110 to prevent air from entering the housing 100 from the filter element disassembly port 110, thereby ensuring the effectiveness and filtration effect of the air filter 300 and guaranteeing the user experience. Furthermore, when the position detection sensor 500 is positioned adjacent to the fresh air disassembly port 810, the position detection element 400 can be positioned adjacent to the disassembly cover 330 corresponding to the position detection sensor 500.

[0106] Of course, since the disassembly cover 330 is provided with a handle groove 331, in some other embodiments, the disassembly cover 330 can be configured to be located inside the housing 100, and a flat cover can be separately and detachably provided at the filter disassembly port 110 to ensure the aesthetics of the air conditioner indoor unit.

[0107] Reference Figure 1 In this embodiment, the filter element removal port 110 is opened on one side of the housing 100 in the horizontal direction. While ensuring the aesthetics of the front side of the air conditioner indoor unit, the orientation of the filter element removal port 110 is more suitable for the force direction of the user or maintenance personnel when removing the air filter 300, which facilitates the user or maintenance personnel to replace and clean the filter 320 in the future.

[0108] Reference Figure 1 and Figure 9 In this embodiment, the housing 100 is provided with an air inlet grille 120 disposed on the rear side of the vertical air conditioner indoor unit, and is located in the upper, middle and lower middle parts of the housing 100.

[0109] Reference Figure 9 In another embodiment of this invention, and differing from the above embodiment, the filter removal port 110 may be opened adjacent to one side of the air inlet grille 120, and the filter 320 may be a filter screen. The filter receiving space 200 may be a space located inside the air inlet grille 120 of the indoor air conditioning unit for arranging the filter screen. In this case, the air filter 300 can be used to filter the ambient airflow that passes through the air inlet grille 120 and exchanges heat with the indoor heat exchanger.

[0110] Reference Figure 9 In this embodiment, the inner side of the air intake grille 120 is provided with a slide rail 130 for limiting the sliding trajectory of the air filter 300, and the wall panel 210 can be a sliding base plate 131 that can support the air filter 300.

[0111] In this embodiment, the position detection sensor 500 can be installed adjacent to the filter element disassembly port 110.

[0112] In another embodiment of the air conditioner indoor unit, the air conditioner indoor unit can be a wall-mounted air conditioner indoor unit. The difference from the above embodiment is that the air inlet grille 120 is disposed on the top side of the wall-mounted air conditioner indoor unit. The fresh air module 700 can be disposed inside the housing 100 and located on the left or right side of the housing 100. The filter removal port 110 can be disposed on the front side of the housing 100, and in order to ensure the aesthetics of the wall-mounted air conditioner indoor unit, a foldable front panel can also be disposed on the front side of the housing 100 to cover the filter removal port 110 and the removal cover 330.

[0113] When the air filter 300 is a filter support frame 310 and a filter screen disposed inside the air inlet grille 120 and in front of the indoor heat exchanger, that is, the air filter 300 is used to filter the ambient airflow that passes through the air inlet grille 120 and exchanges heat with the indoor heat exchanger. At this time, a plate for supporting the front end of the air filter 300 is provided at the adjacent filter disassembly port 110 of the housing 100. This plate is located below the front end of the air filter 300 and extends in the left and right direction, with one plate surface facing upwards. The position detection sensor 500 can be installed on this plate. Of course, the position detection sensor 500 can also be installed on the left wall plate 210 or the right wall plate 210 of the filter disassembly port 110.

[0114] When the air filter 300 is configured as the filter support frame 310 and the pre-filter in the fresh air module 700, the position detection sensor 500 can be configured on the filter base plate 820 of the filter cover 800 in the same way as the above-mentioned vertical air conditioner indoor unit. In this case, the filter removal port 110 can be correspondingly located in front of the fresh air removal port 810.

[0115] In this embodiment, when the air filter 300 needs to be removed from the filter housing space 200 through the filter 320 removal port 110, the air filter 300 can be pulled out of the filter housing space 200 as a whole through the handle groove 331. When the air filter 300 needs to be installed into the filter housing space 200 through the filter 320 removal port 110, first insert the end of the air filter 300 corresponding to the removal cover 330 into the filter housing space 200 through the filter 320 removal port 110, and then push the air filter 300 into the filter housing space 200 as a whole to install the air filter 300 in place.
