Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically to a self-cleaning structure for the filter screen of a heat pump air conditioner. Background Technology

[0002] As people's living standards continue to improve, their requirements for living conditions are also increasing. To address the impact of hot and cold weather on the comfort of their living environment, heat pump air conditioners have become a necessity for most households. During daily use, dust in the living environment can cause the filters of wall-mounted heat pump air conditioners to become clogged. When the filter becomes sufficiently clogged, it can cause the airflow from the heat pump air conditioner to fluctuate, resulting in a poor user experience. Dust accumulation on the heat pump air conditioner filter occurs in two ways: when the air conditioner is in use, because the filter is at the air inlet, dust will accumulate; when the air conditioner is not used for a long time, because there is no obstruction on the filter, dust will also accumulate. Currently, the only solution to clogged filters is for users to clean them regularly. Utility Model Content

[0003] To address the problem of existing heat pump air conditioners being difficult to clean, this utility model provides a self-cleaning structure for the filter of a heat pump air conditioner.

[0004] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0005] A self-cleaning structure for the filter of a heat pump air conditioner includes a heat pump air conditioner body. A placement groove is formed on the top surface of the heat pump air conditioner body, and a filter is placed inside the placement groove. A dust baffle is hinged to the side of the heat pump air conditioner body near the filter. A dust-adhesive pad is connected to the bottom surface of the dust baffle, and the outer wall of the dust-adhesive pad is coated with adhesive. The bottom surface of the dust-adhesive pad contacts the top surface of the filter. Sliding grooves are formed on both sides of the top surface of the heat pump air conditioner body. A driving mechanism is provided inside the sliding grooves. A slider is provided at one end of the driving mechanism, and a connecting rod is hinged to the top surface of the slider. One end of the connecting rod is hinged to one side of the dust baffle.

[0006] Furthermore, the drive mechanism includes a lead screw, which is rotatably connected inside the slide groove, and one end of the lead screw is threadedly connected to one side of the slider.

[0007] The beneficial effect of adopting the above-mentioned further solution is that the lead screw and slider in the drive mechanism are threadedly connected. When the lead screw rotates, it can precisely drive the slider to slide in the groove. This transmission method has the characteristics of high precision and high stability. It can accurately control the opening and closing action of the dust baffle, ensure that the dust pad and the filter screen are tightly attached or separated, make the cleaning process stable and reliable, improve the operating accuracy of the self-cleaning structure, and thus ensure the cleaning effect of the filter screen.

[0008] Furthermore, the drive mechanism also includes a micro motor, the output end of which is connected to one end of the lead screw.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the micro motor, as the power source for driving the lead screw, provides automated power support for the entire drive mechanism. Users do not need to manually operate the drive mechanism; they only need to control the opening and closing of the micro motor to easily realize the movement of the slider and the corresponding action of the dust baffle, which greatly improves the automation level of the filter screen self-cleaning structure.

[0010] Furthermore, an air outlet is provided at the bottom of the heat pump air conditioner body, and an air outlet fan blade is provided inside the air outlet. The air outlet fan blade includes a mounting bracket and a venting blade. The mounting bracket is rotatably connected inside the air outlet, and the venting blade is connected to the bottom of the mounting bracket.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the mounting bracket is rotatably connected inside the air outlet, which allows the air outlet fan blades to flexibly adjust the angle according to the air outlet demand of the air conditioner, optimize the air outlet direction, improve the air outlet efficiency, and make the air blown out by the air conditioner more evenly distributed in the room, thereby enhancing the cooling or heating effect.

[0012] Furthermore, a rear cover is installed on the outer wall of the heat pump air conditioner body, the rear cover including a cover plate, and the cover plate is engaged with the outer wall of the heat pump air conditioner body.

[0013] The beneficial effects of adopting the above-mentioned further solution are that the use of a snap-fit ​​cover facilitates the disassembly and installation of the rear cover. When it is necessary to inspect, clean, or replace parts inside the air conditioner, the operator can quickly open the rear cover, saving operation time, improving maintenance efficiency, and reducing maintenance costs.

[0014] Furthermore, hooks are installed on the outer wall of the cover plate.

[0015] The advantage of adopting the above-mentioned further solution is that the connection of the hook makes it easy to fix the heat pump air conditioner body in a designated safe area.

[0016] Furthermore, the filter screen is distributed in a folded shape on the body of the heat pump air conditioner.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, compared with the traditional flat filter, the folded structure greatly increases the surface area of ​​the filter, improves the dust filtration capacity without increasing the volume of the air conditioner itself, captures more impurities in the air, ensures that the air entering the air conditioner is cleaner, and further improves the overall performance of the air conditioner.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This self-cleaning filter structure for heat pump air conditioners can isolate dust from the filter when the air conditioner is not in use, achieving a dust-proof effect. The structure is simple, low-cost, and provides good dust prevention. Furthermore, the cleaning structure in this invention utilizes an adhesive to clean the filter, making it easy to operate, space-saving, and low-cost. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] As an embodiment of this utility model, the driving mechanism 800 further includes a lead screw 8001, which is rotatably connected inside the slide groove. One end of the lead screw 8001 is threadedly connected to one side of the slider 500. The lead screw 8001 in the driving mechanism 800 is threadedly connected to the slider 500. When the lead screw 8001 rotates, it can precisely drive the slider 500 to slide within the slide groove. This transmission method has the characteristics of high precision and high stability, and can accurately control the opening and closing action of the dust baffle 200, ensuring that the dust sticking pad 700 and the filter screen 900 are tightly attached or separated, making the cleaning process stable and reliable, and improving the operational precision of the self-cleaning structure. To ensure the cleaning effect of the filter screen 900, the drive mechanism 800 also includes a micro motor 8002. The output end of the micro motor 8002 is connected to one end of the lead screw 8001. As the power source for driving the lead screw 8001 to rotate, the micro motor 8002 provides automated power support for the entire drive mechanism 800. Users do not need to manually operate the drive mechanism 800. They only need to control the opening and closing of the micro motor 8002 to easily realize the movement of the slider 500 and the corresponding action of the dust baffle 200. This greatly improves the automation level of the filter screen self-cleaning structure, making it convenient and quick, and enhancing the user experience.

[0030] As an embodiment of this utility model, the heat pump air conditioner body 100 has an air outlet at its bottom end. The air outlet is equipped with an air outlet fan blade 400. The air outlet fan blade 400 includes a mounting bracket 4001 and a venting blade 4002. The mounting bracket 4001 is rotatably connected to the inside of the air outlet. The bottom end of the mounting bracket 4001 is connected to the venting blade 4002. The mounting bracket 4001 is rotatably connected to the inside of the air outlet, so that the air outlet fan blade 400 can flexibly adjust its angle according to the air outlet demand of the air conditioner, optimize the air outlet direction, improve the air outlet efficiency, and make the air blown by the air conditioner more evenly distributed in the room, enhance the cooling or heating effect, and improve the user's comfort.

[0031] As one embodiment of this utility model, a rear cover 300 is further installed on the outer wall of the heat pump air conditioner body 100. The rear cover 300 includes a cover plate 3001, which is snap-fitted onto the outer wall of the heat pump air conditioner body 100. This snap-fit ​​connection facilitates the disassembly and installation of the rear cover 300. When it is necessary to inspect, clean, or replace parts inside the air conditioner, the operator can quickly open the rear cover 300, saving operation time, improving maintenance efficiency, and reducing maintenance costs. The outer wall is equipped with hooks 3002, which facilitates the fixing of the heat pump air conditioner body 100 in a designated safe area. The filter screen 900 is distributed in a folded shape on the heat pump air conditioner body 100. Compared with the traditional flat filter screen, the folded structure greatly increases the surface area of ​​the filter screen 900. Without increasing the volume of the air conditioner body 100, it improves the dust filtration capacity, captures more impurities in the air, ensures that the air entering the air conditioner is cleaner, and further improves the overall performance of the air conditioner.

[0032] Specifically, the working principle of the self-cleaning structure of the filter in this type of heat pump air conditioner is as follows: When the heat pump air conditioner body 100 is working, because the air intake is located above the filter 900, dust is carried by the airflow through the filter, causing it to remain on the filter 900. The cleaning structure includes a dust-adhesive pad 700. A replaceable dust-adhesive pad 900 is installed on the dust baffle 200, with both sides coated with acrylic adhesive. When the dust baffle is closed, the dust-adhesive pad 700 directly contacts the filter 900, carrying away the dust from the filter 900. When the dust-adhesive pad 700 accumulates excessive dust, it is replaced. This effectively prevents clogging and reduces the frequency of cleaning the filter 900. When the heat pump air conditioner is on, the user can choose whether to replace the dust-adhesive pad 700 by observing the dirt on it. Furthermore, the slider has two positions: an open position and a closed position. When the indoor unit of the heat pump air conditioner is working, the micro motor 8002 drives the lead screw 8001 to rotate, causing the slider 500 to move to the open position. During the movement of the slider 500, the connecting rod 600 drives the dust baffle 200 to move, thus opening the dust baffle 200 and allowing the heat pump air conditioner body 100 to operate normally. When the heat pump air conditioner body 100 is not working, the micro motor 8002 drives the lead screw 8002 to reverse, causing the slider 500 to move to the closed position, closing the dust baffle 200 and preventing dust from entering the heat pump air conditioner, thus providing a dust prevention function.
