The upper box body is externally provided with an air conditioner indoor unit module, and the air conditioner indoor unit module has an evaporator. The upper box body is divided into a smoke exhaust chamber and a heat dissipation chamber. An oil fume extractor fan is installed in the smoke exhaust chamber. The heat dissipation chamber is in communication with the smoke exhaust chamber through a heat dissipation air outlet. A condenser is installed in the heat dissipation chamber. The lower cavity is internally divided into a smoke inlet chamber and an atomization chamber by a partition plate. The partition plate is provided with a mesh. An atomization device is installed in the atomization chamber. The condensed water on the evaporator can drip or be transported to the condenser. The condensed water that has not been consumed by the condenser flows into the atomization device, is atomized, and then enters the smoke exhaust chamber through the mesh.

At the same time, in the weather with high humidity, the condensed water is not treated in time, which leads to the risk of water leakage in the oil fume extractor. In addition, the above water-free discharge components have a relatively high failure rate. If a fault occurs, the refrigeration function is basically in a failure state. In addition, the condensed water is atomized and gasified and discharged through the air duct of the oil fume extractor. Due to the excessive humidity of the exhaust smoke, there are hidden dangers such as insulation reduction, short circuit and burnout of the motor, and corrosion of the volute. UTILITY MODEL CONTENTS

[0025] Referring to Figures 1-2 An extractor hood, comprising a smoke suction assembly 1 and a refrigeration assembly 2 arranged above the smoke suction assembly 1.

[0026] Referring to Figure 6 The refrigeration assembly 2 comprises a first shell 21, an evaporator assembly 22, a condenser 24 and a compressor 25, the evaporator assembly 22, the condenser 24 and the compressor 25 are all arranged in the first shell 21, the evaporator assembly 22, the condenser 24 and the compressor 25 are communicated through refrigerant pipelines, the working principle of the refrigeration assembly 2 is same as the prior art, which will not be repeated here.The refrigeration assembly 2 of the embodiment is modularly designed, which is convenient for disassembly and maintenance.

[0027] Referring to Figures 1-6 The extractor hood further comprises an oil cup 3 hung below the smoke suction assembly 1.The oil cup 3 comprises an oil storage area 31 for storing oil generated by the smoke suction assembly 1, and a water storage area 32 for storing condensed water generated by the refrigeration assembly 2.The oil storage area 31 and the water storage area 32 are arranged in front of and behind each other in the oil cup 3, and a partition plate 33 for separating the oil storage area 31 and the water storage area 32 is arranged in the oil cup 3.

[0028] The front side of the oil cup 3 is provided with an oil mark 34 for observing the oil level in the oil storage area 31, reminding the user to clean the oil cup 3. The partition plate 33 is provided with overflow holes 331 for connecting the water storage area 32 and the oil storage area 31, which are arranged along the length direction of the partition plate 33. The bottom of the overflow hole 331 is higher than the top of the oil mark 34, that is, the lower edge of the overflow hole 331 is higher than the upper edge of the oil mark 34. The staggered design of the overflow hole 331 and the oil mark 34 on the oil cup 3 ensures that the waste oil in the oil storage area 31 cannot flow into the water storage area 32, while the condensed water can flow into the oil storage area 31 through the overflow hole 331, ensuring the cleanliness of the water storage area 32 and preventing the waste oil in the oil storage area 31 from contaminating the water storage area 32. The oil cup 3 further comprises a sealing plate 36 for sealing the top of the water storage area 32.

[0029] The oil cup 3 further comprises a water draining assembly 35.
