[0021] 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.

[0022] Please see Figure 1-3 This utility model provides a technical solution for a kitchen refrigeration and air conditioning equipment: it includes a body and a refrigeration system. The body includes an indoor unit 1 and an outdoor unit 2. The indoor unit 1 is installed on the indoor wall or ceiling of the kitchen, and the outdoor unit 2 is installed outdoors. An oil fume filter mechanism is connected to the indoor unit 1. The refrigeration system includes a compressor 3, a condenser 4, an evaporator 5, a throttle valve 6, and a connecting pipe 7. The compressor 3 and the condenser 4 are located inside the outdoor unit 2, and the evaporator 5 and the throttle valve 6 are located inside the indoor unit 1. The compressor 3, the condenser 4, the evaporator 5, and the throttle valve 6 are connected sequentially through the connecting pipe 7 to form a refrigeration cycle. The oil fume filter mechanism is located at the air inlet 8 of the indoor unit 1. The oil fume filter mechanism includes a connecting duct 9, a pre-filter assembly 10, and a post-filter assembly 11. The pre-filter assembly 10 and the post-filter assembly 11 are connected by the connecting duct 9.

[0023] Furthermore, the post-filter assembly 11 is fixedly installed at the air inlet 8 of the indoor unit 1. The post-filter assembly 11 includes a first housing 12 and a drawer-type filter screen placement rack 13 installed on the inner wall of the first housing 12. The center of the filter screen placement rack 13 is provided with a mounting groove 14 for installing the filter screen.

[0024] In this embodiment, the filter screen placement rack 13 adopts a drawer-type structure, which facilitates users to quickly disassemble and replace the filter screen, thereby improving maintenance efficiency.

[0025] Furthermore, an end cap 15 is fixed to one side of the filter screen holder 13, a slot 16 that fits into the end cap 15 is provided on one side of the first housing 12, and a handle 17 is fixed to the outside of the end cap 15.

[0026] Furthermore, a fixing component is provided between the end cap 15 and the slot 16. The fixing component includes a fixing block 18 and a mating groove 19. The fixing block 18 is fixedly installed on the end cap 15, and the mating groove 19 is located in the slot 16 of the first housing 12.

[0027] In this embodiment, the dimensions of the fixing block 18 and the mating groove 19 are mutually adapted. When the end cover 15 is fitted into the slot 16, the fixing block 18 is precisely engaged in the mating groove 19, ensuring a tight connection between the end cover 15 and the first housing 12, preventing the end cover 15 from loosening or falling off due to vibration or other reasons during equipment operation. Simultaneously, the handle 17 facilitates user operation of the end cover 15. When the filter needs to be removed for cleaning or replacement, the user simply grasps the handle 17 and gently pulls the end cover 15 out of the slot 16, thereby removing the filter holder 13 for the corresponding operation.

[0028] Furthermore, the pre-filter assembly 10 is installed in the ceiling of the kitchen. The pre-filter assembly 10 includes a second housing 20 and a lifting bracket 21 installed inside the second housing 20. The two sides of the lifting bracket 21 are slidably connected to the inner wall of the second housing 20 through sliders 22. The inner wall of the second housing 20 is provided with a slide rail 23. The lifting bracket 21 is detachably installed with a pre-filter 24, an activated carbon filter 25, and a HEPA high-efficiency filter 26.

[0029] In this embodiment, the pre-filter assembly 10 is installed in the kitchen ceiling, making full use of the space above the kitchen. It does not occupy floor or wall space and facilitates air filtration. The second housing 20 provides stable support and protection for the entire pre-filter assembly. The lifting bracket 21 is slidably connected to the slide rail 23 on the inner wall of the second housing 20 via a slider 22. This structure allows the lifting bracket 21 to move up and down within the second housing 20, facilitating the installation, removal, and replacement of the filter. The pre-filter 24 effectively intercepts larger dust particles and debris, the activated carbon filter 25 adsorbs odors and harmful gases in the air, and the HEPA high-efficiency filter 26 further filters out tiny particles and bacteria. The three layers of filters work together to greatly improve the air filtration effect, providing a cleaner and healthier air environment for the kitchen.

[0030] Furthermore, the pre-filter 24, activated carbon filter 25, and HEPA high-efficiency filter 26 are stacked sequentially from the outside to the inside, and the inner wall of the lifting bracket 21 is provided with an installation track 27 for installing the pre-filter 24, activated carbon filter 25, and HEPA high-efficiency filter 26.

[0031] In this embodiment, the mounting track 27 ensures that the pre-filter 24, activated carbon filter 25 and HEPA high-efficiency filter 26 are accurately and securely installed in the lifting bracket 21.

[0032] Furthermore, a grid plate 28 is fixed to the bottom of the lifting bracket 21, the grid plate 28 is embedded in the bottom of the second housing 20, and pull rings 29 are fixed to both sides of the bottom of the grid plate 28.

[0033] Furthermore, elastic buckles 30 are installed on both sides of the grille plate 28, and a positioning groove 31 that cooperates with the elastic buckles 30 is provided at the bottom of the second housing 20.

[0034] Furthermore, the primary filter 24 is a metal mesh filter.

[0035] Furthermore, the activated carbon filter 25 is filled with columnar activated carbon, which has a large specific surface area and can more effectively adsorb odors and harmful gases in the air, thereby improving the air purification effect.

[0036] Working Principle: When the kitchen air conditioning unit is running, compressor 3 starts, compressing the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The gaseous refrigerant then enters condenser 4, where it exchanges heat with the outside air, releasing heat and condensing into a high-temperature, high-pressure liquid refrigerant. The liquid refrigerant flows through connecting pipe 7 and then through expansion valve 6, which reduces its pressure, making it a low-temperature, low-pressure liquid refrigerant. This liquid refrigerant then enters evaporator 5. In evaporator 5, the low-temperature, low-pressure liquid refrigerant absorbs heat from the surrounding air and vaporizes, becoming a low-temperature, low-pressure gaseous refrigerant. This also lowers the temperature of the air flowing through evaporator 5. The cooled air is then blown out by the fan of indoor unit 1, achieving the cooling effect.

[0037] Meanwhile, air from the kitchen enters through the air inlet 8 of the indoor unit 1, first passing through the pre-filter assembly 10. The air first passes through the pre-filter 24, which intercepts larger dust particles and debris. Then, the air continues through the activated carbon filter 25, where the columnar activated carbon adsorbs odors and harmful gases. Next, the air passes through the HEPA high-efficiency filter 26, which filters out tiny particles and bacteria. The air filtered by the pre-filter assembly 10 then enters the post-filter assembly 11 through the connecting duct 9 for further filtration and purification. Finally, the purified air enters the indoor unit 1 to participate in the cooling cycle, providing a clean and cool air environment for the kitchen.

[0038] When the filter needs cleaning or replacement, for the pre-filter assembly 10, the user can pull the grille 28 via the pull ring 29. Since the elastic clips 30 on both sides of the grille 28 engage with the positioning grooves 31 at the bottom of the second housing 20, the elastic clips 30 will disengage from the positioning grooves 31 during the pulling process, thereby pulling the lifting bracket 21 out of the second housing 20. Then, according to the installation track 27, the pre-filter 24, activated carbon filter 25, and HEPA high-efficiency filter 26 can be removed in sequence for cleaning or replacement. For the post-filter assembly 11, the user holds the handle 17 and pulls the end cap 15 out of the slot 16, thereby removing the filter holder 13 to clean or replace the filter in the installation slot 14.
