Abstract

A range hood with quick-changing filter function includes a body, a fan set and a middle frame plate group. The body has a lower shell and an upper shell. The upper shell is disposed on the top side of the lower shell. An inside of the lower shell communicates with an inside of the upper shell. The fan set is disposed in the upper shell of the body. The middle frame plate group is disposed on the lower shell of the body. A bottom cover of the middle frame plate group is provided with at least one air inlet. The middle frame plate group is provided with an oil filter fixture that can be used for setting the oil filter. The middle frame plate group is pivotally installed on the lower shell of the body through a rotating mechanism, so that the middle frame plate group can rotate between a first position and a second position. When the middle frame plate group rotates to the first position, the middle frame plate group is located in the lower shell of the body, and can be fixed by means of magnetic attraction or the like. When the middle frame plate group is rotated to the second position, the middle frame plate group is located outside the lower shell of the body, the oil filter is exposed to the outside. Therefore, the oil filter can be cleaned and replaced easily. Thus, the function of quick-changing the filter can be achieved.

Description

Quick screen change range hood

The present invention relates to a range hood with quick screen change, and in particular, to a range hood that facilitates replacement of the oil screen.

The range hood can be said to be one of the necessary equipment in every household's kitchen or in restaurants, food stalls and other catering industries. It can effectively discharge the oil fumes generated when cooking food. Existing range hoods mainly use a fan unit installed inside the body to inhale oil smoke into the body through an oil collection group (including an oil screen and an oil cup). The oil screen can filter out oil dirt, and the oil dirt drips onto the oil cup. The oil fume is first filtered through the oil net, and then the oil fume is discharged outdoors, thereby improving the efficiency of exhausting the oil fume. However, in existing range hoods, it is troublesome to disassemble and assemble the oil screen, making it difficult to quickly change the screen.

The technical problem to be solved by the present invention is to provide a quick screen changing range hood in view of the shortcomings of the existing technology, which can achieve the function of quick screen changing and is simple and easy to operate.

In order to solve the above technical problems, the present invention provides a quick screen-changing range hood, which includes: a body, the body has a lower shell part and an upper shell part, the lower shell part has a top end side and a bottom end side, the The upper shell part is disposed on the top end side of the lower shell part, the lower shell part is internally connected with the upper shell part, the lower shell part has an accommodating space, and the accommodating space is recessed in the front side of the lower shell part, The accommodation space extends into the lower shell part; a fan unit is arranged in the upper shell part of the body; and a middle frame panel group has a bottom cover and a front cover. The bottom cover is provided with at least one air inlet. The front cover is connected to the front end of the bottom cover. The front cover is erected on the bottom cover. At least one oil screen holder is provided on the middle frame panel group. The oil screen holder is It can be used to set the oil screen. The middle frame plate group is arranged on the lower shell of the machine body. When the middle frame plate group is located in the accommodation space, a transparent hole is formed below the bottom cover of the middle frame plate group. The air inlet is connected to the outside of the machine body through the air-permeable area. The middle frame panel group is pivoted to the lower shell of the machine body with a rotating mechanism near the bottom side, so that the middle frame plate group can Rotate between a first position and a second position; wherein when the middle frame plate group rotates to the first position, the middle frame plate group is located in the accommodation space, so that the oil screen holder and the oil filter The net is hidden in the body. When the middle frame plate group rotates to the second position, the middle frame plate group is located outside the accommodation space, so that the oil screen holder and the oil screen are exposed outside the body.

The beneficial effect of the present invention is that the quick screen-changing range hood provided by the present invention includes a body, a fan unit and a middle frame plate set. The body has a lower shell part and an upper shell part, and the lower shell part has a container. The fan unit is installed in the upper shell of the machine body. The middle frame plate group has a bottom cover and a front cover. The bottom cover is provided with an air inlet. The front cover is connected to the front end of the bottom cover. The front cover is erected on the bottom cover. The middle frame plate group is provided with an oil screen holder. The net fixing frame can be used to set the oil net. The middle frame plate group is installed on the lower shell of the machine body. When the middle frame plate group is located in the accommodation space, a permeable area is formed below the bottom cover of the middle frame plate group, allowing people to enter the machine body. The air outlet communicates with the outside of the machine body through the ventilated area, and the middle frame plate group is pivoted to the lower shell of the machine body with a rotating mechanism near the bottom side, so that the middle frame plate group can rotate between the first position and the second position. When the middle frame plate group rotates to the first position, the middle frame plate group is located in the accommodation space, so that the oil screen holder and the oil screen are hidden in the body. When the middle frame plate group rotates to the second position, the middle frame plate group is located in the accommodation space. Outside the accommodation space, the oil screen holder and oil screen are exposed outside the body. Therefore, the present invention can hide the oil screen at the air inlet inside the body, so that when the range hood is running, the user will not see the dirty oil screen. When you need to change the screen, you can use the rotating mechanism to rotate the middle frame plate group forward and open it, together with the oil screen holder. And rotate forward, the replaceable oil screen is placed in the oil screen holder for easy extraction and replacement, which can achieve the function of quick screen change and is simple and easy to operate.
