A range hood with a cooling function comprises a main body 1, a volute fan 2 mounted within the main body 1, a smoke outlet 3 formed at the bottom of the main body 1, the smoke outlet 3 being in communication with the volute fan 2. The volute fan 2 generates negative pressure when in operation, thereby absorbing smoke at the smoke outlet 3. The main body 1 is provided with a front panel 5 and a lower panel 6, and the smoke outlet 3 is provided on the lower panel 6.

[0020] A refrigeration module is further provided in the main body 1. The refrigeration module is installed on the side of the volute fan 2. The refrigeration module includes an evaporator 8 and a condenser 9 connected to the compressor 7. The evaporator 8 is installed in an evaporation box 81. The air inlet of the evaporation box 81 is connected to the air inlet provided at the top of the main body 1. The air outlet of the evaporation box 81 is connected to the cold air outlet 83 provided at the front end of the main body 1 through a cold air pipe 82.

[0021] The condenser 9 is installed in a condensation box 91 , the air inlet of the condensation box 91 is connected to the air inlet arranged on the top of the main body 1 , and the air outlet of the condensation box 91 is connected to the air inlet of the volute fan 2 through a hot air pipe 92 .

[0022] In one embodiment, a bellows 10 is provided inside the main body 1 , the volute fan 2 is installed in the bellows 10 , the bottom of the bellows 10 is connected to the smoking port 3 through the flue, and the air outlet of the hot air pipe 92 is connected to the bellows 10 .

[0023] In one embodiment, a filter frame 11 is provided on the top of the main body 1 , the filter is mounted on the filter frame 11 , and the evaporation box 81 and the condensation box 91 are connected to the filter frame 11 .

[0024] In one embodiment, the evaporation box 81 and the condensation box 91 are installed side by side, and an evaporation wind wheel 84 and a condensation wind wheel 94 are coaxially installed in the evaporation box 81 and the condensation box 91, and the wind wheels are coaxially driven to rotate by the same motor.

[0025] In one embodiment, a soundproof cavity 12 is further provided in the main body 1 . The soundproof cavity 12 is located at the bottom of the evaporation box 81 and the condensation cavity, and the compressor 7 is installed at the bottom of the soundproof cavity 12 .

[0026] In one embodiment, the side wall of the cold air outlet 83 is connected to the cold air pipe 82, and a plurality of air guide bosses 85 are provided in the cold air outlet 83. The air guide bosses 85 are provided with concave arc air guide surfaces facing the air inlet.

[0027] How it works

[0028] When the range hood is turned on, the volute fan 2 located inside the main body 1 begins to operate. This operation generates negative pressure, drawing cooking fumes through the intake vent 3 located on the lower panel 6. The drawn-in fumes are guided by the volute fan 2 and discharged along the flue, preventing them from spreading throughout the kitchen.

[0029] The advantage of this design is that the negative pressure suction of the volute fan enables the oil smoke to be efficiently adsorbed and removed, especially during high-temperature cooking, which can effectively prevent the oil smoke from polluting the kitchen environment, thereby maintaining the cleanliness of the kitchen and the air quality.

[0030] When cooling is desired, compressor 7 activates, and the refrigerant evaporates in evaporator 8, absorbing heat and producing cool air. Evaporator 8 is housed within evaporator box 81, whose air inlet is connected to the top air inlet of main body 1. Outside air enters evaporator box 81 through the air inlet. The cooled air is then transported through cold air duct 82 to cold air outlet 83 at the front of main body 1. Ultimately, the cool air is blown directly toward the front of the kitchen, providing a comfortable, low-temperature environment for cooks.

[0031] During the cooling process, condenser 9 is responsible for releasing the heat from the refrigerant. It is housed within a condenser box 91, the air inlet of which is also connected to the air inlet on the top of the main unit 1. After entering condenser box 91, outside air cools the condenser and is heated to become hot air. This hot air is then directed through hot air duct 92 into the air inlet of volute fan 2 and ultimately exhausted from the kitchen.

[0032] Through this design, the utility model can not only reduce the temperature synchronously during the process of absorbing and exhausting oil smoke, but also realize the effective separation of cold air and hot air through a reasonable air flow path, thereby avoiding secondary heat diffusion.

[0033] To further enhance the user experience, the present invention provides a soundproof chamber 12 within the main body 1. This chamber is located at the bottom of the evaporator 81 and condenser 91, and the compressor 7 is mounted at its base. This chamber effectively isolates the noise generated by the compressor and other operating components, reducing the impact of the range hood's operation on the surrounding environment.

[0034] Furthermore, a filter holder 11 is located on top of the main body 1. The filter is mounted on this holder and docked with the evaporator 81 and condenser 91. This design allows the air entering the range hood to be filtered, preventing dust and fume particles from entering the refrigeration system and improving system durability. Furthermore, the filtered air is cleaner, further enhancing the air quality in the kitchen environment.

[0035] In summary, this utility model, a range hood with a cooling function, effectively reduces kitchen temperature and improves user comfort during cooking by integrating a cooling module, optimizing air flow paths, and providing a soundproof chamber and filter. Furthermore, it reduces interference with the living environment during operation, further enhancing the user experience and is therefore suitable for widespread adoption.
