Description

Technical Field

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

[0002] In order to enhance the cooking experience, people have invented various refrigeration-type range hoods, which can realize all the functions of range hoods and the functions of air conditioners. For example, the "A Kind of Air-conditioning Range Hood" disclosed in the Chinese Utility Model Patent with Patent No. 202122814657.X (Authorization Announcement No. CN216557289U), the range hood is equipped with a wind valve at the outlet of the range hood fan for switching one of the first and second smoke exhaust channels to be connected to the outlet of the range hood fan, and the condenser is arranged in the first smoke exhaust channel. When the refrigeration system is started, the wind discharged by the range hood fan will be blown to the condenser. Since the wind contains many oil fume particles, in order to keep the surface of the condenser clean, it is often necessary to add an additional electrostatic device to filter these fine particles, which not only increases the cost but also brings the risk of error. At the same time, the internal space of the range hood is relatively small, and the requirements for space layout become higher. Moreover, electrostatic devices often cannot completely remove the oil fume particles in the wind. When the wind from the fan blows towards the condenser, it will contaminate the surface of the condenser and reduce the working efficiency and life of the condenser. The range hood needs to add a three-way device to the smoke pipe and adopt a dual-channel structure. The first smoke exhaust channel constitutes a heat dissipation channel, and the second smoke exhaust channel constitutes a direct exhaust channel. In different working modes, the smoke can be discharged from the heat dissipation channel or the direct exhaust channel by switching the air valve. And after the smoke enters the heat dissipation channel, it needs to make two 90° bends before being discharged, which has a large wind resistance and affects the smoke exhaust effect. Because it is necessary to consider the exhaust path of the wind under two working conditions and avoid drilling two holes in the wall, the wind discharged from these two paths needs to be finally converged and discharged outdoors. The additional three-way device increases the cost compared to a single smoke pipe, and because the smoke pipe has many bends, it is not conducive to the exhaust of oil smoke. Utility Model Content
