Description

Technical Field

[0001] This utility model relates to a kitchen air conditioning system. Background Technology

[0002] In both home and commercial kitchens, cooking generates significant amounts of heat, fumes, and various odorous gases, causing a rapid increase in kitchen temperature and a marked decline in air quality. This not only affects the comfort of the cook but can also have adverse health effects if one is exposed to such an environment for an extended period. Therefore, the need for temperature control and air purification in kitchens is increasingly prominent, becoming a key factor in improving the kitchen user experience.

[0003] Currently, most traditional air conditioning units on the market are designed for ordinary indoor spaces such as living rooms and bedrooms, and have significant limitations when adapting to the special usage scenarios of kitchens. On the one hand, the core function of traditional air conditioners focuses on circulating and cooling or heating indoor air, and cannot introduce and replenish fresh outdoor air. During cooking in the kitchen, because the range hood continuously exhausts indoor air, if fresh air cannot be replenished in time, a negative pressure environment can easily form in the kitchen. This may not only reduce the exhaust efficiency of the range hood, but may also allow polluted outdoor air to flow back through gaps in doors and windows, further deteriorating indoor air quality. At the same time, a long-term lack of fresh air circulation will also increase the carbon dioxide concentration in the kitchen, affecting the breathing comfort of people indoors.

[0004] On the other hand, traditional air conditioners typically use a horizontal, direct-blowing airflow method, which can easily conflict with the exhaust airflow of kitchen range hoods. During cooking, range hoods capture and expel fumes by creating a negative pressure zone. However, the horizontal airflow from traditional air conditioners directly interferes with the airflow around the range hood, disrupting the stability of the negative pressure zone. This results in some fumes not being effectively captured, leading to their diffusion and escape. This not only reduces the exhaust efficiency of the range hood but also causes fumes to adhere to kitchen walls, cabinets, and appliance surfaces, increasing cleaning difficulty. Furthermore, it further deteriorates indoor air quality, posing a potential threat to the health of those cooking.

[0005] In summary, current traditional air conditioning equipment has significant shortcomings in kitchen temperature regulation, fresh air supply, and smoke extraction in conjunction with range hoods. There is an urgent need for a new kitchen air treatment solution that can simultaneously address kitchen temperature regulation and fresh air supply, effectively cooperate with range hoods to improve smoke extraction, and possess good energy efficiency, in order to solve the problems existing in the current technology. Utility Model Content

[0006] The first technical problem to be solved by this utility model is to provide a kitchen air conditioning system that can supplement fresh outdoor air while providing air temperature regulation, in light of the above-mentioned existing technology.

[0007] The second technical problem to be solved by this utility model is to provide a kitchen air conditioning system that can provide an air curtain for the range hood and improve the smoke extraction effect, in view of the above-mentioned existing technology.

[0008] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: a kitchen air conditioning system, including an air conditioning module, the air conditioning module including a shell and a compressor, the shell having a heat dissipation duct and an indoor unit duct, the heat dissipation duct having a condenser and a condenser fan installed inside, the indoor unit duct having an evaporator and an evaporator fan installed inside, the compressor, condenser and evaporator being connected through a refrigerant pipeline, characterized in that: the heat dissipation duct has a first air inlet and a first air outlet, the indoor unit duct has a second air inlet and a second air outlet, the first air inlet is always connected to the outside, the second air outlet is always connected to the kitchen interior, in the air conditioning-only mode, the first air outlet is connected to the outside, the second air inlet is connected to the kitchen interior, in the mode where both the air conditioner and the range hood are on, the first air outlet is connected to the kitchen interior, and the second air inlet is connected to the outside.

[0009] Preferably, the kitchen air conditioning system further includes a first duct, a second duct, a third duct, a first switching valve, and a second switching valve. The first air inlet is connected to the outside through the first duct, the second duct is connected to the first switching valve and is connected to the outside, and the third duct is connected to the second switching valve and is connected to the inside. In the air conditioning-only mode, switching the first switching valve connects the first air outlet to the second duct through the first switching valve, and switching the second switching valve connects the second air inlet to the third duct through the second switching valve. In the mode where both the air conditioner and the range hood are on, switching the first and second switching valves connects the first air outlet to the third duct through the second switching valve, and the second duct connects to the second air inlet through the first switching valve.

[0010] Further preferably, both the first and second switching valves are three-way valves, and the system also includes a fourth, fifth, sixth, and seventh duct. The second duct is connected to the first port of the first switching valve, the third duct is connected to the first port of the second switching valve, the first end of the fourth duct is connected to the first air outlet, and the second end of the fourth duct is connected to the fifth duct. The first end of the fifth duct is connected to the second port of the first switching valve, and the second end of the fifth duct is connected to the second port of the second switching valve. The first end of the sixth duct is connected to the second air inlet, and the second end of the sixth duct is connected to the third port of the second switching valve. The first end of the seventh duct is connected to the third port of the first switching valve, and the second end of the seventh duct is connected to the sixth duct. With this configuration, by switching the two three-way valves and connecting the seven ducts, the system can switch the airflow between the first air outlet and the second air inlet in different operating modes.

[0011] The technical solution adopted by this utility model to solve the second technical problem mentioned above is as follows: a ventilation hole is opened in the kitchen ceiling, and the third air duct is connected to the ventilation hole, which is located above the front of the range hood. With this arrangement, when both the range hood and air conditioner are on, the air blown out of the ventilation hole can flow downwards along the wall of the range hood, forming an air curtain between the cook and the range hood, which helps to improve the smoke extraction effect.

[0012] The compressor can be installed in multiple different locations; preferably, the compressor is installed inside the housing.

[0013] In order to allow the heat of the compressor to be carried away through the heat dissipation duct, the compressor is located inside the heat dissipation duct.

[0014] To avoid interference between the heat from the cooling duct and the cold air from the indoor unit duct, the cooling duct and the indoor unit duct are isolated from each other.

[0015] Compared with the prior art, the advantages of this utility model are as follows: the first air inlet of the heat dissipation duct of the kitchen air conditioning system is always connected to the outside, and the second air outlet of the indoor unit duct is always connected to the kitchen interior. In the mode where only the air conditioner is on, the first air outlet of the heat dissipation duct is connected to the outside, and the second air inlet of the indoor unit duct is connected to the kitchen interior. When both the air conditioner and the range hood are on, the first air outlet is connected to the kitchen interior, and the second air inlet is connected to the outside. Thus, while regulating the kitchen air temperature, it can also replenish fresh outdoor air and avoid the formation of a negative pressure environment in the kitchen. Attached Figure Description
