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-type range hoods are disclosed in the prior art. When working, condensed water will condense on the surface of the evaporator. At present, the condensed water is usually directly discharged by drilling holes in the wall for external discharge or introducing the condensed water into the sewer pipe through a pipe for external discharge. This not only increases the cost, but also makes the condensed water easy to accumulate, causing local water leakage. In addition, the direct discharge of condensed water is also easy to cause long-term erosion of the user's external wall and dripping in the external environment. As an improvement, the "A Kind of Air-conditioning Range Hood" disclosed in the Chinese invention patent application with application number 202110917866.9 (application publication number CN 115704568) is a kind of air-conditioning range hood. The condensed water discharged from the air-conditioning indoor unit of the air-conditioning range hood flows into the first water receiving box through the first water inlet joint. The condensed water in the first water receiving box can be transported to the condenser to cool the condenser after being discharged to improve its heat exchange effect. The condensed water that is not evaporated by the condenser can also flow back to the first water receiving box to achieve the reuse of condensed water. For example, the Chinese invention patent application with application number 202210002129.0 (application publication number CN 115342400 A) discloses "An air-conditioned range hood and its dehumidification control method". A compressor and a range hood fan are provided in the 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 a water box. A liquid distributor is installed on the condenser. The water in the water box is transported to the liquid distributor through a water pump, and the condensed water flowing down the surface of the condenser flows back into the water box. A liquid level sensor is installed in the water box. In the dehumidification mode, the controller controls the working status of the compressor, the air-conditioning indoor unit and the water pump accordingly by receiving the liquid level feedback signal of the liquid level sensor. The above patents all disclose solutions for cooling the condenser using condensed water, but do not use condensed water to clean the range hood fan. During daily use of the refrigeration range hood, a large amount of grease will remain on the volute and impeller. After a long period of air drying and solidification, these grease will form a hard grease layer on the volute and impeller, which is very difficult to clean. In addition, the existing refrigeration range hood does not provide a solution for using condensed water to clean the external items of the range hood. In summary, the existing refrigeration range hood needs to be further improved. Utility Model Content
