Abstract

A cabinet built-in range hood is provided and is disposed in a cabinet that the thickness is within 350 mm. The range hood includes a body, a fan set, a lifting casing and an electric push rod. The fan set is disposed on an upper shell of the body, and an air inlet of the fan set is turned to the front side and the rear side, so that the thickness of the body can be reduced and the body is thinned to accommodate in the cabinet. The body can be installed through hanging elements to facilitate installation. The lifting casing can be liftably disposed in a lower shell of the body. The lifting casing can be pushed up and down through the electric push rod. A direction of airflow can be changed through lifting the lifting casing down close to the cooker, so that oil fume will tilt to the rear sides before it rises. It can prevent users from exposuring oil fume, and can improve the effect of oil fume removal. The electric push rod is disposed outside a pollution area of the body to increase a service life, to prevent from oil pollution and to facilitate the convenience of the replacement and maintenance.

Description

Cabinet built-in range hood

The invention relates to a cabinet-embedded range hood, and in particular to a cabinet-embedded range hood that can be installed in a cabinet.

A range hood is one of the essential equipments in every household kitchen or in restaurants, snack stands and other catering businesses. It can effectively discharge the fumes generated when cooking food. The conventional range hood mainly uses a fan unit installed inside the machine body to suck the fumes into the machine body through an oil collection unit (including an oil screen and an oil cup). The oil screen can filter out the grease, which drips into the oil cup. The fumes are first filtered by the oil screen and then discharged to the outside, thereby providing the efficiency of exhausting fumes.

The hidden range hood is installed in the cabinet. In order to be flush with the cabinet, it will be shallower than the gas stove countertop, resulting in poor fume removal effect. Furthermore, it is difficult to reduce the thickness of the existing range hood, making it difficult to make the range hood thin and difficult to accommodate it in a cabinet.

The technical problem to be solved by the present invention is to provide a cabinet-embedded range hood in view of the shortcomings of the existing technology, which can reduce the user's exposure to oil smoke and improve the oil smoke removal effect.
