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. They add air conditioning components on the basis of the range hood platform, which can realize all the functions of the range hood and the function of the air conditioner. When working in the refrigeration mode, the condenser needs to dissipate heat. At present, the condenser is usually placed in the oil fume channel and cooled by the oil fume fan. For example, the "range hood" disclosed in the Chinese utility model patent with patent number 201620118025.6 (authorization announcement number CN 205481215U) has the condenser arranged in the exhaust chamber. Although the air with oil fume can be purified by the centrifugal fan of the range hood to dissipate the heat of the condenser, as the working time increases, oil stains will adhere to the condenser, thereby affecting the heat exchange capacity of the condenser, and then affecting the refrigeration effect. At present, it is usually necessary to install a purification device at the front end of the condenser. After the purification device is installed, it is easy to cause the exhaust channel to be unsmooth and the noise is high. In addition, the purification device has a high cost and a high failure rate, and requires regular maintenance. In addition, some refrigeration-type range hoods use clean air to dissipate heat from the condenser, but the heat-dissipated air is eventually discharged through a common flue. This type of structure is equivalent to occupying part of the fan performance of the range hood, thereby reducing the oil fume extraction effect of the range hood fan. In summary, further improvements need to be made to the existing refrigeration-type range hoods. Utility Model Content
