Abstract

The invention discloses a thin smoke machine, which comprises: a box body, a deflector is arranged in the box, an air inlet is arranged on the deflector, and the deflector is at least partly double-sided in the area surrounding the air inlet. The lower surface and the upper surface of the double-sided air diversion area constitute the air inlet diversion surface and the air outlet diversion surface respectively, and both the air inlet diversion surface and the air outlet diversion surface gradually extend upward toward the air inlet; Fan assembly, the fan assembly is set in the box, the fan assembly includes: a centrifugal wind wheel and a volute, the volute is set above the deflector, the centrifugal wind wheel is set in the volute, and the air inlet end of the fan assembly is set towards the air inlet , the airflow blown from the air outlet end of the fan assembly flows through the air outlet guide surface. According to the thin hood of the embodiment of the present invention, the circumferential eddy current loss is reduced, not only the flow is optimized, the air volume loss is reduced, but also the noise and smoking effect are improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, and more specifically, to a thin cigarette machine. Background technique [0002] There are many types of range hoods. In addition to the common near-suction type and European type, there is also a thin type, and some are also called ultra-thin range hoods. The so-called ultra-thin range hood refers to the flat design of the hood, and the overall height of the hood is designed to be small, generally not exceeding the height of the hood. Ultra-thin range hoods include external circulation models and internal circulation models. For the external circulation model, the conventional understanding is that the smoke machine extracts the smoke oil from the room, and after treatment, it is finally discharged to the outside through the pipe. For the internal circulation model, the conventional understanding is that the smoke machine extracts the smoke oil from the room, and finally discharg...
