[0023] Referring to Figures 1-2 A range hood, comprising a smoke suction assembly 2 and a refrigeration assembly 1 arranged above the smoke suction assembly 2. The refrigeration assembly 1 comprises a first shell 11, an evaporator assembly 12, a compressor 15 and a condenser 16. The evaporator assembly 12, the compressor 15 and the condenser 16 are all arranged in the first shell 11, and the evaporator assembly 12, the compressor 15 and the condenser 16 are connected in communication through refrigerant pipelines. The working principle of the refrigeration assembly 1 is the same as that of the prior art, which will not be described herein.

[0024] The smoke suction assembly 2 comprises a second shell 21 and a fan 23 arranged inside the second shell 21. The front side of the second shell 21 is provided with an air inlet 211, and the smoke suction assembly 2 comprises an oil screen 22 arranged at the air inlet 211. The fan 23 comprises a volute 232 and an impeller 233 arranged in the volute 232. The fan 23 further comprises a fan input end 231 corresponding to the oil screen 22. The condenser 16 is arranged at a downstream position of the volute 232.

[0025] The evaporator assembly 12 comprises a third shell 121 and an evaporator 122 arranged in the third shell 121. The third shell 121 comprises a receiving portion 1211 capable of receiving the condensed water generated by the evaporator 122. The refrigeration assembly 1 further comprises a drain pipe 13 capable of draining the condensed water in the receiving portion 1211, and further comprises a distributor 14 capable of receiving the condensed water drained by the drain pipe 13 and distributing the condensed water to the oil mesh 22.

[0026] Referring to Figures 3-7 The distributor 14 comprises a distributor body 141 for receiving the condensed water drained by the drain pipe 13, a distribution hole 142 for draining the condensed water in the distributor body 141, and a liquid distribution plate 143 for receiving the condensed water drained from the distribution hole 142. The distribution hole 142 is arranged at the bottom of the distributor body 141. The distribution hole 142 is at least two and is arranged in the length direction of the distributor body 141. The liquid distribution plate 143 is arranged below the distribution hole 142, and the liquid distribution plate 143 corresponds to the oil mesh 22.

[0027] The distributor 14 is located at the front side of the oil mesh 22, one end of the liquid distribution plate 143 is connected to the front side of the bottom of the distributor body 141, the other end of the liquid distribution plate 143 gradually inclines downward from front to back, and the end of the liquid distribution plate 143 away from the distributor body 141 corresponds to the upper part of the front side of the oil mesh 22.

[0028] The drain pipe 13 comprises a drain pipe input end 131 and a drain pipe output end 132, the drain pipe input end 131 is in communication with the receiving portion 1211, and the drain pipe output end 132 is in communication with the inner side of the distributor body 141. The inner side of the distributor body 141 is provided with a support 144 for fixing the drain pipe output end 132.

[0029] The oil mesh 22 comprises a flat plate portion 221 at the upper part of the oil mesh 22 and a honeycomb-shaped oil mesh hole 222 below the flat plate portion 221. The oil mesh 22 comprises a spoke 223 constituting the oil mesh hole 222, and the lower end of the liquid distribution plate 143 corresponds to the flat plate portion 221.

[0030] After the refrigeration assembly 1 moves, the condensed water generated by the evaporator 122 flows into the distributor 14 through the drain pipe 13. The drain pipe output end 132 is fixed on the support 144 of the distributor body 141, and the condensed water collected in the distributor body 141 generates uniformly distributed water droplets through the distribution hole 142. After the water droplets fall on the liquid distribution plate 143, the shape of the three-dimensional water droplets changes to planar water droplets. Preferably, the gap between the liquid distribution plate 143 and the oil mesh 22 is controlled to be between 0.5mm and 2mm, which ensures that the planar water droplets adhere to the flat plate portion 221 of the oil mesh 22. If the gap is too large, the planar water droplets may not fall along the surface of the oil mesh 22, and if the gap is too small, water may accumulate in the gap and fall unevenly.

[0031] The water continues to flow down along the flat portion 221 of the oil mesh 22, is split when passing through the honeycomb spokes 223, is recombined, is split again, and the water flow path is continuously expanded, and the water flow speed is gradually slowed down. At the same time, the spokes 223 are continuously fed with fine water flows under the action of the fan 23 into the volute 232, and the high-speed rotation of the impeller 233 impacts the condensate water droplets to cause atomization, and the atomized water droplets are discharged to the outside using high wind speed, with high atomization efficiency.

[0032] Since the condensate water is distributed throughout the oil mesh, the air inlet temperature of the smoking assembly 2 is directly reduced. The oil mesh 22 treated with condensate water is also more conducive to heat dissipation of the condenser 16 and improves the heat exchange effect.
