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. On the basis of the range hood platform, an air conditioning component is added. The compressor, condenser and evaporator are connected through a refrigerant pipeline. The refrigeration-type range hood can realize all the functions of the range hood and the function of the air conditioner. When working, condensed water will condense on the surface of the evaporator of the air conditioner. At present, the condensed water is usually directly discharged to the outside by drilling holes in the wall or introducing the condensed water into the sewer pipe through a pipe for external discharge. This not only increases the cost, but also the condensed water is easy to accumulate, causing local 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 Chinese invention patent application with application number 202110917866.9 (application publication number CN 115704568) discloses an "air-conditioned range hood". The condensed water discharged from the air-conditioning indoor unit of the air-conditioned range hood flows into the first water receiving box through the first water inlet joint. After being discharged, the condensed water in the first water receiving box can be transported to the condenser to cool the condenser 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 the 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. Although the above-mentioned air-conditioning range hoods all disclose a solution in which the air-conditioning condensed water is transported to the condenser and the unconsumed condensed water flows back into the water box, the structure is relatively conventional, the condensed water transport device and the indoor module are independent of each other, and the system structure is not compact enough and needs further improvement.
