Description

Technical Field

[0001] This utility model relates to the field of kitchen air conditioning technology, and in particular to a kitchen air conditioner. Background Technology

[0002] A kitchen air conditioner is a type of air conditioning equipment specifically designed for kitchens. It is suitable for operation in high-temperature and heavy oil fume environments. Through directional air delivery, it will not affect the flame of the gas stove, ensuring high safety. The main functions of a kitchen air conditioner include rapid cooling, oil fume prevention, and corrosion prevention. It can operate stably in high-temperature and oil fume environments, providing a comfortable cooking environment.

[0003] A search revealed a Chinese patent for a kitchen air conditioner (authorization announcement number CN214172422U), comprising a housing and an air conditioning system disposed within the housing. The housing has an air outlet for supplying air conditioning air to the kitchen and an air inlet for drawing air from the kitchen. A first filter is disposed between the air conditioning system and the air inlet. The air inlet includes a first air inlet duct and a second air inlet duct arranged independently of each other. The second filter is disposed within the first air inlet duct, and a first damper that can be opened and closed is disposed at the inlet of the first air inlet duct. An oil-gas separator is disposed within the second air inlet duct, and a second damper that can be opened and closed is disposed at the inlet of the second air inlet duct. This patented technology can effectively reduce the risk of the air inlet filter becoming clogged, thereby helping to improve the air conditioning effect.

[0004] However, the above-mentioned devices still have some drawbacks in actual use. The most obvious one is that the air conditioning unit needs to be installed in the ceiling to achieve an aesthetic effect. However, the space available above the ceiling is limited, and the unit includes many components such as the compressor, evaporator and condenser. Therefore, its structure needs to be set up to be relatively compact, which makes it difficult to increase the heat exchange area. Utility Model Content

[0019] By adopting the above technical solution and setting up the mounting bracket, it is possible for staff to install the air conditioner in the entire kitchen.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, during the operation of the kitchen air conditioner, the compressor compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas, which is then sent to the condenser for condensation. In the condenser, the high-temperature, high-pressure gas exchanges heat with the outdoor air through the outdoor fan, cooling into a liquid refrigerant. The liquid refrigerant enters the evaporator after being throttled by the expansion valve, where it evaporates and absorbs heat from the indoor air, thereby achieving a cooling effect. The evaporated gaseous refrigerant is then compressed again by the compressor to complete a cycle. The above structure ensures sufficient contact between the condenser and the outdoor air, thereby improving the heat exchange efficiency. Furthermore, while ensuring the heat exchange rate, the kitchen air conditioner adopts a compact and integrated design to achieve rational utilization of limited space.

[0022] 2. In this utility model, the mounting bracket is suitable for different ceiling conditions, is easy to install and does not affect the aesthetics of the kitchen.

An indoor fan 2 is fixedly installed inside the air conditioner housing 1 on the side near the indoor air outlet 15. An outdoor fan 8 is fixedly installed on the inner wall of the air conditioner housing 1 on the side of the outdoor air outlet 14. A compressor 6 is fixedly installed inside the air conditioner housing 1 above the indoor fan 2. A condenser 7 is fixedly installed at the top of the inner wall of the air conditioner housing 1. An expansion valve 9 is fixedly installed at the bottom of the inner wall of the air conditioner housing 1. An evaporator 10 is fixedly installed on the inner wall of the air conditioner housing 1 on the side of the expansion valve 9. During the operation of the kitchen air conditioner, the compressor 6... The system compresses low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas, which is then sent to condenser 7 for condensation. In condenser 7, the high-temperature, high-pressure gas exchanges heat with outdoor air through outdoor fan 8, cooling into liquid refrigerant. The liquid refrigerant then enters evaporator 10 after being throttled by expansion valve 9, where it evaporates and absorbs heat from the indoor air, thus achieving a cooling effect. The evaporated gaseous refrigerant is then compressed again by compressor 6 to complete a cycle. This structure ensures full contact between condenser 7 and outdoor air, thereby improving heat exchange efficiency. Furthermore, while ensuring the heat exchange rate, the kitchen air conditioner adopts a compact and integrated design to achieve rational utilization of limited space.

[0030] Specifically, two air inlets a3 are fixedly installed at the bottom of the air conditioner housing 1. An isolation plate 4 is installed on the inner wall of the air conditioner housing 1, positioned on one side of the expansion valve 9 and evaporator 10. Several bolts are installed inside the isolation plate 4. The isolation plate 4 effectively seals the expansion valve 9 and evaporator 10 within it, ensuring a rational overall layout. The air conditioner housing 1 and the isolation plate 4 are connected by bolts. Both the expansion valve 9 and the evaporator 10 are in contact with the inner side of the isolation plate 4. The bolts also secure the position of the isolation plate 4. The isolation plate 4 serves to protect the expansion valve 9 and the evaporator 10. The expansion valve 9 can be used to regulate the flow and pressure of the refrigerant. The indoor air outlet 15 is connected to the interior of the indoor fan 2, and the outdoor air outlet 14 is connected to the interior of the outdoor fan 8. The outdoor fan 8 and the indoor fan 2 are symmetrically arranged. A perforated plate 16 is installed inside the air conditioner housing 1 and above the condenser 7. The perforated plate 16 can increase the air intake area in a limited space, thereby improving the heat exchange efficiency of the condenser 7. Heat dissipation holes are arrayed on both sides of the air conditioner housing 1.

[0031] Specifically, a partition plate 5 is fixedly installed inside the air conditioner housing 1. The partition plate 5 divides the air conditioner housing 1 into two spaces, making the entire space of the air conditioner housing 1 more compact. The interior of the air conditioner housing 1 is divided into two parts by the partition plate 5. The partition plate 5 is in contact with the edge of the isolation plate 4. An installation plate 11 is installed on the outside of the compressor 6. The installation plate 11 adds a protective structure to the outside of the compressor 6, making the compressor 6 more stable during operation. A capillary tube 13 is fixedly connected to the outside of the compressor 6. Two mounting brackets 12 are installed on both sides of the air conditioner housing 1. The installation brackets 12 facilitate the installation of the entire kitchen air conditioner by the staff.

[0032] Working principle: First, the mounting bracket 12 is suitable for different ceiling conditions, making installation convenient and not affecting the aesthetics of the kitchen. The expansion valve 9 can be used to regulate the flow and pressure of the refrigerant. During the operation of the kitchen air conditioner, the compressor 6 compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas, which is then sent to the condenser 7 for condensation. In the condenser 7, the high-temperature, high-pressure gas exchanges heat with the outdoor air through the outdoor fan 8, cooling into liquid refrigerant. The liquid refrigerant enters the evaporator 10 after being throttled by the expansion valve 9, where it evaporates and absorbs heat from the indoor air, thus achieving a cooling effect. The evaporated gaseous refrigerant is then compressed again by the compressor 6 to complete a cycle. The above structure ensures sufficient contact between the condenser 7 and the outdoor air, thereby improving the heat exchange efficiency. While ensuring the heat exchange rate, the kitchen air conditioner adopts a compact and integrated design. The partition plate 5 divides the air conditioner casing 1 into two spaces, making the entire space of the air conditioner casing 1 more compact and facilitating the arrangement of various structures.
