Description

Technical Field

[0001] The utility model relates to a range hood, in particular to a refrigeration type range hood. Background Art

[0002] Various refrigeration range hoods are disclosed in the prior art. An air conditioning component is added to the range hood platform. The compressor, condenser and evaporator are connected through a refrigerant pipeline. The refrigeration range hood can realize all the functions of the range hood and the function of the air conditioner. When the existing refrigeration range hood works in the refrigeration mode, condensed water will be generated. In order to avoid the discharge of condensed water, the condensed water is usually introduced into a liquid distributor, and then evenly distributed on the surface of the condenser through the liquid distributor, and the evaporation consumption is realized by heat exchange with the condenser surface. For example, the Chinese invention patent application with application number 202210002129.0 (application publication number CN115342400A) discloses "An air-conditioned range hood and its dehumidification control method". The range hood has a compressor and a range hood fan in its casing, and an air-conditioning indoor unit is installed on the casing. The air-conditioning indoor unit includes an evaporator, and a condenser is installed in the smoke exhaust channel. The condensed water condensed on the surface of the evaporator can flow into the water box. A liquid distributor is installed on the condenser, and the water in the water box is transported to the liquid distributor by a water pump. The condensed water is evaporated and consumed by the heat of the condenser. However, the liquid distributor is unstable due to the influence of the installation angle and the material. Sometimes the condensed water is unevenly distributed, resulting in poor heat exchange and evaporation consumption with the condenser surface. Once the weather humidity is relatively high, the condensed water is difficult to handle and still needs to be discharged. Utility Model Content
