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. The refrigeration type range hood integrates an air conditioning module and an oil fume extraction module. The condenser of the air conditioning module is usually placed in the smoke exhaust channel, and the oil fume airflow is used to dissipate heat from the condenser, but the heat dissipation effect is not good. For this reason, as an improvement, a Chinese utility model patent with patent No. 202121615051.7 (authorization announcement No. CN215863614U) discloses "A liquid distributor and an air-conditioning type range hood using the liquid distributor". The air-conditioning type range hood allows the condensed water condensed on the surface of the evaporator to flow to the condenser through the liquid distributor, and the condensed water is used to cool the condenser. The water cooling is combined with air cooling, and the heat dissipation effect is better. However, when the condensed water flows through the surface of the condenser, the unconsumed condensed water will still drip from the condenser, thereby affecting the reliability of the range hood. Moreover, the condenser is in the oil fume channel. As the working time increases, oil stains will adhere to the condenser, thereby affecting the adhesion ability of the condensed water on the condenser and reducing the water treatment capacity. Another example is the "Kitchen Air Conditioning Equipment with Oil Fume Filter" disclosed in the Chinese invention patent application with application number 201710215540.5 (application publication number CN 107036165 A). The kitchen air conditioning equipment includes a kitchen air conditioner main body, an air outlet grille is provided on the kitchen air conditioner main body, a diffuser is provided below the air outlet grille, an air quality sensor is provided on one side of the air outlet grille, and a gas sensor is provided below the air quality sensor. An exhaust fan is installed inside the kitchen air conditioner main body, an oil and gas separation net is provided behind the exhaust fan, and a composite filter net is provided behind the oil and gas separation net. The oil and gas separation net and the composite filter net of the kitchen air conditioner only filter the oil fume, and do not process the air conditioning condensate water. Utility Model Content

The lower cavity body 7 is arranged at the bottom of the upper box body 6. An oil cup 8 is installed at the bottom of the lower cavity body 7.

[0025] Along the flow direction of the oil fume airflow, a composite filter 5 is detachably installed in the air duct upstream of the air inlet of the oil fume exhaust fan 1, and the composite filter 5 can be removed or installed as needed. In this embodiment, the oil fume exhaust fan 1 is a vertically arranged centrifugal fan, and the composite filter 5 is vertically arranged and blocks the air inlet of the oil fume exhaust fan 1. Figure 3 and Figure 4 As shown, the composite filter screen 5 of this embodiment includes an oil absorption screen 51 , a water retaining screen 52 , and an intermediate layer evaporation screen 53 sandwiched between the oil absorption screen 51 and the water retaining screen 52 .

[0026] When working in the cooling mode, condensed water will condense on the surface of the evaporator 41. A water receiving box 91 is installed below the evaporator 41. The condensed water flows into the water receiving box 91 and is transported to the condenser 31 through a water pump 92 and a water outlet pipe 93. The composite filter 5 of this embodiment is arranged below the condenser 31. The condensed water that is not consumed by the condenser 31 flows to the middle layer evaporation net 53 of the composite filter 5 through the water pipe 10.

[0027] The range hood fan 1 of this embodiment is a centrifugal fan and is vertically arranged, including a volute 11, and a vent 12 is opened on the ring wall of the volute. The heat dissipation fan 32 of this embodiment is also a centrifugal fan and is vertically arranged, and the central axis of the impeller of the range hood fan 1 is parallel to the central axis of the impeller of the heat dissipation fan 32. The heat dissipation fan 32 is arranged above the range hood fan 1, and the air outlet of the heat dissipation fan 32 faces downward and toward the vent 12. The air outlet of the heat dissipation fan 32 can be fluidly connected with the inside of the volute 11 through the vent 12.
