Abstract

The invention relates to a baffle that can improve the efficiency of extracting and exhausting oil fume, which includes a frame and baffles arranged in it, and the baffles are arranged in the shape of a "back" at equal intervals, or increase or decrease from outside to inside Decreases, the baffles slope or curve toward the center of the shroud. An oil collector is arranged at the center of the deflector. The frame is provided with buckles for clamping with the lower periphery of the range hood. The present invention can overcome the diffusion of oily fume airflow, so that all the oily fumes are discharged through the range hood so as not to spread indoors, so that the range hood's smoke extraction rate can be improved, and the kitchen environment can be further purified. The present invention can be matched with the air curtain machine arranged on the gas cooker, and can also be used alone.

Description

A shroud capable of improving the efficiency of extracting and exhausting oil fumes

technical field

The invention relates to a device used in conjunction with a range hood, which is one of the supporting equipment for a kitchen air-conditioning environment, smoke insulation, heat insulation and fresh air system, in particular to a deflector cover capable of improving the efficiency of range hood. the

Background technique

The range hood is a kitchen appliance that purifies the kitchen environment. It is installed above the gas stove, and can quickly suck away the waste burned by the gas stove and the harmful oil fume produced during the cooking process. At present, range hoods have become commonly used or even necessary kitchen utensils in the kitchens of families and restaurants. However, the air flow at the smoke outlet on the casing of the existing range hoods is easy to diffuse, and all the smoke cannot be sucked clean, resulting in smoke exhaust. When the machine is matched with the stove, the range fume rate is low. the

Contents of the invention

In view of the above-mentioned problems in the prior art, the object of the present invention is to provide a shroud that can improve the efficiency of extracting and exhausting oil fume, which can overcome airflow diffusion and improve the efficiency of extracting and exhausting oil fume. the

The technical solution adopted by the present invention to achieve its purpose: a deflector cover that can improve the efficiency of oil fume extraction, including a frame and deflectors arranged in it, and the deflectors are arranged at intervals in the shape of "back" and Slopes or curves toward the center of the hood. the

The spacing of the guide vanes is equidistant or increases or decreases from outside to inside, and an oil collector is arranged at the center of the guide vanes. the

The frame is provided with buckles for clamping with the lower periphery of the range hood. the

The beneficial effect of the present invention is that it can overcome the diffusion of the oil fume airflow, guide the oil fume to be discharged through the range hood so as not to spread indoors, improve the range hood's extraction rate of the range hood, and further purify the kitchen environment. The present invention can be matched with the air curtain machine arranged on the gas cooker, and can also be used alone.

Detailed ways

Below in conjunction with accompanying drawing for further detailed description:

As shown in Figure 1 and 2. The deflector 3 includes a frame 3.3, and inside the frame there are deflectors 3.1 in the shape of a "back". The deflectors are arranged at equal intervals and inclined or bent toward the center of the cover, so that the oil fume can be guided to the center of the cover and discharged. The distance between the baffles can also gradually increase or decrease from outside to inside. An oil collector 3.2 for centralized oil collection is also provided at the central position of the shroud. The frame is provided with buckles for clamping with the lower periphery of the range hood, and can also be connected by screws.

As shown in Figure 3, the present invention has a matching combination structure with the range hood, the frame 3.3 of the guide cover 3 is fixed on the casing 1 of the range hood, and the deflector 3.1 is not in contact with the inner cover plate of the range hood, that is, the flow guide Sheet 3.1 is suspended below the inner cover of the range hood. Because the deflector is inclined or bent toward the center of the hood, the oil fume is guided to the center of the hood and discharged through the exhaust pipe 2. The present invention can not only overcome the influence of hot air diffusion to the room due to the blocked reflection of the gas jet flow above the range hood in the kitchen air-conditioning environment, smoke insulation and heat insulation fresh air system, but also overcome the diffusion of oil fume flow, improve the efficiency of oil fume extraction by more than 20%, and purify indoor air environment, protect kitchen equipment, and benefit human health. the
