Description

M241608 4. Creation Description (1) [Technical Field to which the New Type belongs] This creation relates to the improvement of the structure of a range hood filter (2), especially a type that can completely cover the exhaust hood exhaust vent, and can ensure that Exhaust hood filters that do not get stuck in the exhaust vents have innovative structure improvement and application. [Prior art]

It can be said that the range hood is one of the necessary products in the catering industry, such as the kitchens of various households, restaurants, snack stalls, etc., which can be effectively absorbed and filtered by the cooking utensils during use. The fume hood is installed above the place where the food is cooked, so that the fume generated when the food is enjoyed can be sucked into the interior by the fume hood and through the fume exhaust pipe. It is discharged outwards to avoid the smoky and stained oils everywhere in the room, or the health impact on the body; however, although this method can effectively eliminate the oily smoke generated during cooking, it is easy to cause exhaustion. A large number of sticky oil on the fan, such as a fan that is used to suck and remove the oil fume, will cause a lot of inconvenience and trouble for the user to clean up.

Therefore, an industry researcher has developed a filter structure, as shown in the fourth figure. The filter (4) is connected to an integrally formed mesh frame (4 1). A number of viscous bodies (4 2 ), Which can be used for fixing the filtering material (4 3), and several inserts (44) are protruded upward from the outer edge of the net frame (4 1), so as to be able to embed the inherent magnetic body (45); The magnetic body (4 5) in the grid (4 1) insert (4 4) can be used to be adsorbed outside the exhaust vent (1 1) of the range hood (1), so that the oil can be adsorbed in advance. Filter material (4 3) to avoid oil fume

The improved structure of the exhaust hood filter in this creation (2) is mainly formed by a convex ring edge protruding upward from the outer edge of the net frame, and a convex body is provided on the convex ring edge for accommodation of the magnetic body. This way, when the mesh frame is adsorbed outside the exhaust hood exhaust opening by the magnetic body of the accommodating groove, there will be no gap due to the blocking of the convex ring edge between the grill and the exhaust hood exhaust opening. It can prevent oil from getting stuck inside the range hood. At the same time, the mesh frame and filter material can be adsorbed outside the exhaust hood of the range hood without using a larger diameter volume. It is not only cheaper in production cost, but also Increase the money spent on warehousing and transportation, and make it more practical and convenient for the overall implementation. In this creation, the filter structure of the range hood is improved (2). A metal magnetic guide is additionally provided between the magnetic body and the range hood to increase the adsorption force. It can not only be more firmly adsorbed on the range hood, but also not affected by Thick and thin oil pollution, but more practical characteristics.
