Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioning electric purification module structure. Background Technology

[0002] With the increasing popularity of air conditioning equipment and the growing safety awareness of users, air conditioning systems integrating electro-purification functions (such as electrostatic dust removal and ion sterilization) have become the mainstream in the market. These devices typically achieve deep air treatment through a high-voltage powered electro-purification module, while relying on a low-voltage detection module to monitor its operating status. To ensure safe use, the electro-purification module must automatically disconnect the high-voltage power supply during disassembly and cleaning to avoid the risk of electric shock caused by exposed, live electrode plates.

[0003] In traditional design schemes, the power supply control of the electric purification module adopts a mechanical contact switch and electrode plate linkage mechanism.

[0004] During installation, when the electro-purification module is inserted into the rear frame of the air conditioner, it simultaneously presses two types of contacts: a mechanical contact switch and electrode plates. The mechanical contact switch provides low-voltage power. When the mechanical contact switch is pressed, it sends an electro-purification module presence signal to the main control system. The main control system then supplies high-voltage power to the electrode plates, which contact the electro-purification module, activating the electro-purification function.

[0005] During the disassembly phase, when the electric purification module is pulled out, theoretically the contact switch and the high-voltage electrode plate should be separated from the electric purification module simultaneously, thereby immediately cutting off the high-voltage power supply.

[0006] However, this solution has certain drawbacks. The electro-purification modules are mostly large-area plate-like structures, making it difficult for users to ensure strict vertical displacement during actual operation. If the electro-purification module is pried up from one side at an angle, the electrode plates may detach from the contact first, while the mechanical contact switch remains in contact. At this time, the main control system, because it continues to receive the presence signal from the contact switch, mistakenly judges that the electro-purification module is still in the installation state, and the high-voltage power supply has not been cut off. This results in the exposed electrode plates remaining energized, and users will face the risk of direct electric shock when touching the electrode plates. Utility Model Content

[0007] To address the technical problem that existing devices are prone to electrode de-energization delay, posing a significant risk of electric shock to users, this utility model provides an air conditioning electric purification module structure.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] The structure of the air conditioner electric purification module includes the air conditioner rear frame, electric purification module, electrode plates, detection components and main control system;

[0010] The rear frame of the air conditioner has a mounting slot, and the electric purification module is installed in the mounting slot.

[0011] The electro-purification module has contact points;

[0012] The electrode sheet is installed on the periphery of the mounting groove. The electrode sheet has electrical conductivity and has an elastic extension that extends toward the center of the mounting groove.

[0013] The detection components include a Hall sensor and a magnet. The Hall sensor is fixed to the periphery of the mounting slot, and the magnet is set at the edge of the electric purification module. There are inductive and non-inductive states between the Hall sensor and the magnet.

[0014] When the electric purification module is installed, the contact point of the electric purification module first contacts the elastic extension part. As the electric purification module continues to penetrate into the installation groove, the elastic extension part undergoes elastic deformation. The magnet moves towards the Hall sensor to a preset distance. At this time, the magnet and the Hall sensor are in a sensing state, triggering the main control system to supply power to the electrode plate.

[0015] When the electric purification module is disassembled, it begins to detach from the mounting slot, the elastic extension springs back to its original position, the magnet moves away from the Hall sensor, and then moves away from the preset distance. The magnet and the Hall sensor are in a non-inductive state, triggering the main control system to cut off the power to the electrode plate.

[0016] Furthermore, the rear frame of the air conditioner is equipped with vertical beams and horizontal beams. The two ends of the vertical beams are connected to the rear frame of the air conditioner, one end of the horizontal beam is connected to the vertical beam, and the other end of the horizontal beam is connected to the rear frame of the air conditioner. The vertical beams, horizontal beams, and rear frame of the air conditioner form an installation groove.

[0017] Furthermore, it also includes mounting brackets, which consist of vertical mounting beams and horizontal mounting beams connected to each other. The vertical mounting beams are mounted on the vertical beams, and the horizontal mounting beams are mounted on the horizontal beams.

[0018] Furthermore, both the Hall sensor and the electrode plate are mounted on the vertical mounting beam. Both the vertical and horizontal mounting beams have wiring grooves. The system also includes a first transmission line and a second transmission line. One end of the first transmission line is connected to the Hall sensor, and the other end of the first transmission line is led out along the wiring groove through one end of the vertical mounting beam. One end of the second transmission line is connected to the electrode plate, and the other end of the second transmission line is led out along the wiring groove through one end of the horizontal mounting beam. This separates the first and second transmission lines to avoid signal interference.

[0019] Furthermore, a limiting post is provided on the vertical mounting beam, and a corresponding limiting hole is provided on the electrode plate. The limiting post is inserted into the limiting hole and fits tightly to restrict the radial movement of the electrode plate and the limiting post. There is a fixing post on the vertical mounting beam, and a screw hole is opened at the top of the fixing post. A through hole is provided on the electrode plate, and a screw for fixing is also included. The head of the screw passes through the through hole and is threaded into the screw hole. The tail of the screw presses against the electrode plate to restrict the axial movement of the electrode plate and the fixing post.

[0020] Furthermore, the vertical beams, horizontal beams, and rear frame of the air conditioner are arranged to form four mounting slots.

[0021] Furthermore, the electrode sheet includes a central support portion and an elastic extension portion. The elastic extension portions are located on opposite sides of the central support portion. The central support portion of the electrode sheet is mounted on a vertical mounting beam. The elastic extension portions on both sides of the electrode sheet extend into two adjacent mounting slots respectively. The contact points of the electro-purification module are provided with slots, and the elastic extension portions engage with the slots.

[0022] Furthermore, it also includes a coarse filter screen, which is fixedly installed at the opening of the mounting slot to shield the electro-purification module inside the mounting slot.

[0023] The beneficial effects of this utility model are:

[0024] This solution utilizes the synergistic effect of a Hall sensor, a magnet, and an elastic extension to achieve automatic power-on and power-off control during the installation and removal of the electro-purification module. During installation, as the electro-purification module is pushed into the mounting slot, the contact point first contacts the elastic extension, causing it to deform. The magnet moves closer to the Hall sensor (the sensing limit distance) as the module penetrates deeper into the mounting slot. The Hall sensor then outputs a power-on signal to the main control system, energizing the electrode plates. During removal, as the module detaches from the mounting slot, the elastic extension rebounds, and the magnet moves away from the Hall sensor beyond the sensing limit distance. The Hall sensor outputs a power-off signal, and the main control system immediately cuts off the power supply to the electrode plates. Through the physical linkage between elastic deformation and magnetic induction distance, the power-off action is completed before the electrode plates are exposed, completely eliminating the risk of electric shock to the user.

[0025] Furthermore, even if the user tilts and pries the electric purification module from one side to disassemble it, during the springback process of the elastic extension, the elastic extension is still in contact with the contact point of the electric purification module. The magnet will move away from the Hall sensor and beyond the sensing threshold along with the electric purification module, triggering the main control system to cut off the power to the electrode plate. The power-off action is completed before the electrode plate is exposed, completely eliminating the risk of electric shock to the user. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the present invention will be further described below with reference to the accompanying drawings.

[0037] First, it should be stated that the technical solutions of the embodiments of this application are clearly and completely described. The described embodiments are only some of the embodiments of this application, and not a limitation of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0038] In the description of this utility model, it should be understood that the terms "first", "second", "upper", "lower", "left", "right", "inner", "outer", "axial" or "radial" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and are not intended to indicate or imply that the device or element referred to must have a specific orientation structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0039] Reference Figures 1 to 9 This utility model provides a structure for an air conditioning electric purification module.

[0040] like Figures 1 to 9 As shown, in an embodiment of this solution, an air conditioner electric purification module structure is provided, including an air conditioner rear frame 1, an electric purification module 2, electrode plates 3, a detection component and a main control system (the main control system is a prior art component and is therefore not shown).

[0041] The rear frame 1 of the air conditioner has a mounting groove 4. The electric purification module 2 is installed in the mounting groove 4. It can be fixed by snap-fit, screw or bolt, or other auxiliary fixing components can be set to fix the electric purification module 2, such as spring, buckle or limit block.

[0042] The electric purification module 2 has contact points. The contact points should be made of copper, aluminum, silver or their alloys to ensure conductivity. A slot 15 can be set at the contact points for the electrode sheet 3 to be inserted. Alternatively, the contact points can be set as round, sheet or plate-shaped contacts, or spring contacts with built-in spring elements (such as springs or spring sheets) to ensure stable contact pressure.

[0043] The electrode 3 is installed around the mounting groove 4. The electrode 3 has conductivity and has an elastic extension 32 extending towards the center of the mounting groove 4. The installation of the electrode 3 around the mounting groove 4 should be understood as follows: the electrode 3 can be installed on the side wall of the mounting groove 4 or in the vicinity of the mounting groove 4. The part of the electrode 3 other than the elastic extension 32 should be covered with an insulating plastic shell to prevent accidental contact by the user.

[0044] The detection components include a Hall sensor 5 and a magnet 6. The Hall sensor 5 is fixed around the mounting groove 4 (similar to the electrode plate 3 being installed around the mounting groove 4). The magnet 6 is located at the edge of the electric purification module 2. The magnet 6 can be embedded in the edge of the electric purification module 2, or it can be fixed to the edge of the electric purification module 2 with glue, or other fixing methods. The Hall sensor 5 and the magnet 6 have a sensing state and a non-sensing state.

[0045] When the electric purification module 2 is installed, the contact point of the electric purification module 2 first contacts the elastic extension part 32. The electric purification module 2 continues to penetrate into the installation groove 4, and the elastic extension part 32 generates elastic deformation. The magnet 6 moves towards the Hall sensor 5 to a preset distance. At this time, the magnet 6 and the Hall sensor 5 are in a sensing state, triggering the main control system to supply power to the electrode plate 3. The preset distance is the sensing limit distance between the magnet 6 and the Hall sensor 5. If it is greater than this sensing limit distance, it cannot be sensed.

[0046] When the electric purification module 2 is disassembled, the electric purification module 2 begins to detach from the mounting slot 4, the elastic extension 32 springs back and resets, and the magnet 6 moves away from the Hall sensor 5. When the magnet 6 detaches from the mounting slot 4 along with the electric purification module 2, the distance between the magnet 6 and the Hall sensor 5 is greater than the preset distance (i.e., the sensing limit distance). Then the magnet 6 and the Hall sensor 5 are in a non-inductive state, triggering the main control system to cut off the power to the electrode plate 3.

[0047] This solution utilizes the synergistic action of Hall sensor 5, magnet 6, and elastic extension 32 to achieve automatic power-on and power-off control during the installation and removal of the electric purification module 2. During installation, as the electric purification module 2 is pushed into the mounting slot 4, the contact point first contacts and deforms the elastic extension 32. Magnet 6 moves closer to Hall sensor 5 to a preset distance (the sensing limit distance) as the electric purification module 2 penetrates deeper into the mounting slot 4. Hall sensor 5 then outputs a power-on signal to the main control system, energizing electrode plate 3. During removal, as the electric purification module 2 detaches from the mounting slot 4, elastic extension 32 rebounds, and magnet 6 moves away from Hall sensor 5 beyond the sensing limit distance. Hall sensor 5 outputs a power-off signal, and the main control system immediately cuts off the power supply to electrode plate 3. Through the physical linkage between elastic deformation and magnetic induction distance, the power-off action is completed before electrode plate 3 is exposed, completely eliminating the risk of electric shock to the user.

[0048] like Figures 1 to 3 As shown, specifically how the mounting slot 4 is formed, in this embodiment, a vertical beam 7 and a horizontal beam 8 are provided inside the air conditioner rear frame 1. The two ends of the vertical beam 7 are connected to the air conditioner rear frame 1, and one end of the horizontal beam 8 is connected to the vertical beam 7, while the other end of the horizontal beam 8 is connected to the air conditioner rear frame 1. The vertical beam 7, the horizontal beam 8, and the air conditioner rear frame 1 together form the mounting slot 4. There can be two, three, or more mounting slots 4. To ensure a sufficient number of mounting slots 4 for installing the electric purification module 2, and to guarantee good purification effect and symmetrical aesthetics, four mounting slots 4 are preferably provided. In addition to the configuration shown in this embodiment, the mounting slot 4 can also be integrally formed directly on the air conditioner rear frame 1. It should be noted that those skilled in the art should clearly understand that the mounting slot 4 should penetrate the air conditioner rear frame 1 to ensure that air enters the air conditioner through the mounting slot 4.

[0049] like Figures 2 to 4As shown, this embodiment provides a mounting bracket 9 for providing a mounting position for the Hall sensor 5 and the electrode plate 3. Of course, in addition to the mounting form of this embodiment, the Hall sensor 5 and the electrode plate 3 can also be directly mounted on the rear frame 1 of the air conditioner. The mounting bracket 9 of this embodiment includes a vertical mounting beam 91 and a horizontal mounting beam 92. The vertical mounting beam 91 and the horizontal mounting beam 92 are connected to each other. The vertical mounting beam 91 is mounted on the vertical beam 7, and the horizontal mounting beam 92 is mounted on the horizontal beam 8. For the mounting bracket 9, the horizontal mounting beam 92 can be set only on one side of the vertical mounting beam 91, that is, the mounting bracket 9 is approximately T-shaped. The horizontal mounting beam 92 can also be set on both sides of the vertical mounting beam 91, that is, approximately cross-shaped.

[0050] like Figures 2 to 4 As shown, both the Hall sensor 5 and the electrode plate 3 are mounted on the vertical mounting beam 91. Both the vertical mounting beam 91 and the horizontal mounting beam 92 have wiring grooves, and the system also includes a first transmission line and a second transmission line. One end of the first transmission line is connected to the Hall sensor 5, and the other end is led out along the wiring groove through one end of the vertical mounting beam 91. One end of the second transmission line is connected to the electrode plate 3, and the other end is led out along the wiring groove through one end of the horizontal mounting beam 92. This separate routing of the first and second transmission lines avoids signal interference. Since the first transmission line connected to the Hall sensor 5 is a low-voltage signal line, while the second transmission line connected to the electrode plate 3 is a high-voltage wire, to prevent the high-voltage wire and the low-voltage signal line from being close together and affecting signal transmission, the first transmission line is routed along the vertical mounting beam 91 and led out, while the second transmission line is routed along the horizontal mounting beam 92 and led out. The two lines are perpendicular to each other and far apart, avoiding the influence of the high-voltage wire on the low-voltage signal line.

[0051] like Figures 5 to 7 As shown, a limiting post 10 is provided on the vertical mounting beam 91, and a corresponding limiting hole 11 is provided on the electrode plate 3. The limiting post 10 is inserted into the limiting hole 11 and fits tightly, restricting the radial movement of the electrode plate 3 and the limiting post 10. There is a fixing post 12 on the vertical mounting beam 91. The top of the fixing post 12 is provided with a screw hole 13. A corresponding through hole 14 is provided on the electrode plate 3. It also includes a screw for fixing. The head of the screw passes through the through hole 14 and is threaded into the screw hole 13. The tail of the screw presses against the electrode plate 3, restricting the axial movement of the electrode plate 3 and the fixing post 12. This ensures that the electrode plate 3 is well fixed. The part of the electrode plate 3 except for the elastic extension 32 should be covered with an insulating plastic shell to prevent accidental contact by the user.

[0052] like Figure 1 As shown, preferably, in order to ensure that there are enough mounting slots 4 to install the electric purification module 2, and to ensure good purification effect and symmetrical aesthetics, the vertical beam 7, the horizontal beam 8 and the air conditioner rear frame 1 are arranged to form 4 mounting slots 4.

[0053] like Figures 5 to 9 As shown, the electrode sheet 3 includes a central support portion 31 and an elastic extension portion 32. The elastic extension portions 32 are located on opposite sides of the central support portion 31. The central support portion 31 of the electrode sheet 3 is mounted on the vertical mounting beam 91. The elastic extension portions 32 on both sides of the electrode sheet 3 extend into two adjacent mounting slots 4, respectively. The contact points of the electro-purification module 2 are provided with slots 15, and the elastic extension portions 32 are engaged with the slots 15. In this embodiment, the elastic extension portion 32 can be bent at a certain angle or extended in a straight line, and the extension end has a corresponding structure that cooperates with the slot.

[0054] Electrode 3 includes a positive electrode and a negative electrode, such as Figure 4 As shown, the positive and negative electrodes have the same structure and are close to each other. They are connected to the second transmission line respectively. When the electric purification module 2 is in contact with both the positive and negative electrodes at the same time, it obtains voltage.

[0055] like Figure 1 As shown, this embodiment also includes a coarse filter 16, which is fixedly installed at the opening of the mounting groove 4 to shield the electric purification module 2 inside the mounting groove 4 and to perform preliminary purification of the incoming air, filtering out larger dust impurities.
