Description

Technical Field

[0001] This utility model relates to the field of air purification equipment, and in particular to an air purifier with heating and dehumidification functions. Background Technology

[0002] An air purifier is a device that improves indoor air quality. It uses various technologies to remove pollutants from the air, providing people with a cleaner and healthier breathing environment. Their working principles vary, with passive purification being a common method. Passive purification primarily relies on mechanical filters, such as HEPA filters, which capture particles through direct interception and inertial impaction. While effective against fine particles, HEPA filters have high air resistance and require regular replacement.

[0003] To adapt to different usage conditions in different regions, air purifiers with heating and dehumidification functions have emerged. They are home appliances that integrate multiple functions such as air purification, heating, and dehumidification, providing users with a more comfortable and healthy indoor environment.

[0004] Some air handling equipment that integrates dehumidification functions typically seal the filter cartridge by directly contacting the end of the filter with the sealing gasket during installation. When disassembling and replacing the filter cartridge, the pressure of the sealing gasket forces the user to pull the filter cartridge out forcefully or with special tools, increasing the difficulty of maintenance. To address this issue, an air purifier with heating and dehumidification functions is proposed. Utility Model Content

[0034] 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.

[0035] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an air purifier with heating and dehumidification functions, including a shell 1 with an air inlet on the lower front side, which serves as the main frame of the entire air purifier, supporting and protecting all internal components. The lower front side has an air inlet, and the rear side has heat dissipation holes to dissipate the heat generated by the compressor 21 and condenser 22 in the dehumidification mechanism 2 during operation. The upper part of the shell 1 is equipped with a panel and a touch panel, and the inner wall has a micro-fan. The lower inner wall of the shell 1 is equipped with the dehumidification mechanism 2. A filter element 6 is fixedly installed on the upper part of the shell 1 near the dehumidification mechanism 2 via a limiting component 5, used to filter particulate matter, odors, harmful gases, and other impurities in the air, purifying the passing air and improving its efficiency. Regarding air quality, the outer shell 1 is fixedly installed with the mounting shell 3 near the rear side of the filter element 6 via the disassembly assembly a4; the limiting assembly 5 includes a support base 51 fixedly connected to the inner wall of the outer shell 1, which provides a mounting and support base for components such as the abutment 52 and the rotating ring 54, ensuring the stability of the overall structure of the limiting assembly 5. The abutment 52 is slidably connected to the inner wall of the support base 51 in the vertical direction, and its upper part contacts the filter element 6. The movement of the abutment 52 can achieve the tightening or loosening of the filter element 6. A sealing gasket is fixedly installed on the upper part of the abutment 52. It is a rubber gasket, which can enhance the sealing with the filter element 6 and prevent unfiltered air leakage. The lower part of the abutment 52 is evenly provided with guide grooves 53, which provide guidance for the sliding of the limiting component 55 and ensure that the limiting component 55 moves along a predetermined trajectory.

[0036] Reference Figure 3 - Figure 5A rotating ring 54 is rotatably connected to the inner wall of the support base 51. The inner side of the rotating ring 54 contacts the outer side of the abutment 52. By rotating, it can drive the limiting member 55 and the operating block 56 to move synchronously. The lower part of the rotating ring 54 is fixedly connected to the limiting member 55. The limiting member 55 slides through the guide groove 53 on the lower outer side of the abutment 52. By changing its position, it limits or releases the abutment 52. By coinciding with the guide groove 53, the abutment 52 and the limiting member 55 are released from superposition, allowing the abutment 52 to slide up and down, thereby enabling the filter element 6 to be quickly pressed or released. The outer side of the rotating ring 54 is fixedly connected to the operating block 56. The operating block 56 passes through and slides on the outer side of the support base 51. The operating block 56 allows the user to rotate the rotating ring 54, thereby controlling the working state of the limiting component 5. The outer side of the support base 51 is provided with a protrusion. The outer side of the operating block 56 is engaged with the protrusion to prevent the rotating ring 54 from rotating accidentally and to ensure the reliability of the limiting.

[0037] Reference Figure 3 , Figure 5 and Figure 6 The limiting member 55 is L-shaped and cooperates with the rotating ring 54 to fit against the lower outer side of the abutment member 52. The abutment member 52 has an "I"-shaped cross-section. The upper part of the limiting member 55 away from the abutment member 52 is an inclined surface, and the lower part of the abutment member 52 near the guide groove 53 is also an inclined surface. Through the cooperation of the two sets of inclined surfaces, the limiting member 55 can be lifted upward to compress the rubber sealing gasket. The rear side of the mounting shell 3 is convex to provide installation space for the disassembly assembly a4. The disassembly assembly a4 includes two sets of pressing members 41 that are slidably connected to the inner wall of the convex part of the mounting shell 3. When the pressing members 41 are pressed, the limiting rod 42 can be moved to realize the disassembly or installation of the mounting shell 3 and the outer shell 1. The opposite sides of the two sets of pressing members 41 are fixed. Two sets of limiting rods 42 slide on the inner wall of the mounting shell 3 and are inserted into the inner wall of the buckle 44 under the action of the elastic element 43, thereby fixing the mounting shell 3 to the outer shell 1. The two sets of limiting rods 42 are provided with elastic elements 43 on opposite sides. The elastic elements 43 are bent columnar elastic metals that are snapped into the inner wall of the mounting shell 3 on the outside to prevent misalignment. The limiting rods 42 are subjected to elastic force so that they can be stably inserted into the buckle 44 to ensure the stability of the mounting shell 3 after installation. The elastic element 43 is fixedly installed on the inner wall of the mounting shell 3. Buckles 44 are fixedly connected to the upper and lower sides of the outer shell 1 near the mounting shell 3. The limiting rods 42 are inserted into the inner wall of the buckle 44. The buckle 44 and the limiting rods 42 cooperate to provide a fixing point for the mounting shell 3 and ensure a reliable connection between the mounting shell 3 and the outer shell 1.

[0038] Reference Figure 4 and Figure 7The dehumidification mechanism 2 includes an evaporator 23, which is fixedly connected to the inner wall of the front side of the outer casing 1. The refrigerant evaporates and absorbs heat in the evaporator 23, which lowers the temperature of the air flowing through the evaporator 23. The moisture in the air condenses into water droplets when it encounters the condenser, thereby achieving the purpose of dehumidification. A condenser 22 is fixedly installed on the inner wall of the rear side of the outer casing 1. The refrigerant releases heat in the condenser 22, which condenses the high-temperature and high-pressure refrigerant vapor into a liquid. At the same time, it heats the air passing through, which helps to reduce the relative humidity of the air. The evaporator 23 and the condenser 22 are fixedly connected by a compressor 21. The compressor 21 compresses the refrigerant, causing it to circulate between the evaporator 23 and the condenser 22, thereby transferring heat and providing energy for the dehumidification process. A partition 24 is provided between the evaporator 23 and the condenser 22 to separate the spaces where they are located, prevent untreated and treated air from mixing, ensure that the dehumidification and heating processes proceed in an orderly manner, and improve dehumidification efficiency. A fan 25 is fixedly installed on the outside of the partition 24. The air outlet of the fan 25 is on the rear side, so that outside air enters from the air inlet, passes through the evaporator 23, and some air is guided by the fan 25 to the outside of the condenser 22 to cool the condenser 22 and heat the air at the same time, while reducing the amount of air entering from the heat dissipation holes.

[0039] Furthermore, a water collection box 26 is installed near the lower part of the outer casing 1, close to the evaporator 23, to collect the condensate generated by the evaporator 23 during dehumidification. A cover plate 27 is fixedly installed on the rear side of the outer casing 1 near the water collection box 26 via a disassembly assembly b7, which shields and protects the water collection box 26, preventing dust and other impurities from entering and also making the equipment look cleaner. The disassembly assembly b7 has the same structure as the disassembly assembly a4 but different specifications; its function is to fix the cover plate 27 to the outer casing 1 and facilitate the removal of the cover plate 27 so that the user can remove the water collection box 26 for cleaning or emptying.

[0040] Working principle: When in use, air enters the equipment from the air inlet at the lower front of the outer casing 1, and is dehumidified by the dehumidification mechanism 2 and purified by the filter element 6. Under the action of the fan 25 and the micro fan on the inner wall, the air is discharged from the air outlet at the rear, completing the dehumidification and purification cycle.

[0041] During the dehumidification process, the compressor 21 starts, compresses the refrigerant into high-temperature and high-pressure vapor and delivers it to the condenser 22. The refrigerant releases heat in the condenser 22 and condenses into a high-pressure liquid, which then flows to the evaporator 23. In the evaporator 23, the refrigerant evaporates rapidly and absorbs heat, causing the temperature of the air flowing through the evaporator 23 to drop sharply. The moisture in the air condenses into water droplets when it encounters the condenser and drips into the water collection box 26 at the bottom for collection.

[0042] The heat released by the refrigerant in the condenser 22 heats the air passing through, reducing the relative humidity of the air. At the same time, the fan 25 guides some air to flow through the outside of the condenser 22, which not only cools the condenser 22 but also further heats the air, improving the comfort of the dehumidified air. In addition, the partition 24 separates the space between the evaporator 23 and the condenser 22, preventing untreated air from mixing with treated air and ensuring dehumidification and heating efficiency.

[0043] The dehumidified air flows upward and passes through filter element 6, which filters out impurities such as particulate matter, odors, and harmful gases in the air, thus purifying the air.

[0044] When the filter element 6 needs to be disassembled, press the two sets of pressing parts 41, which will drive the limiting rod 42 to compress the elastic part 43 and disengage it from the buckle 44, so that the mounting shell 3 can be removed.

[0045] Since the sealing gasket on the upper part of the abutment 52 abuts against the filter element 6, the operating block 56 is rotated so that its outer side disengages from the protrusion on the outer side of the support base 51. At this time, the rotating ring 54 rotates synchronously with the operating block 56, driving the limiting member 55 fixed at the lower part of the rotating ring 54 to rotate until the limiting member 55 corresponds to the guide groove 53 at the lower part of the abutment 52, and the limiting member 55 disengages from limiting the abutment 52.

[0046] After the limit is released, the abutment 52 can slide up and down on the inner wall of the support base 51. At this time, the tightness between the upper part of the abutment 52 and the filter element 6 is released, and the upper sealing gasket is also separated from the filter element 6. The filter element 6 can then be removed and replaced.

[0047] When it is necessary to disassemble and assemble the cover plate 27 and the water collection box 26, the disassembly component b7 has the same structure as the disassembly component a4 and the operation is the same as that of the disassembly component a4. The cover plate 27 can be removed, and then the water collection box 26 can be taken out to clean the condensate.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
