Abstract
Description
Technical Field
[0001] The utility model relates to a pull - type range hood with automatic opening and closing.
Background Art
[0002] A range hood is a common kitchen appliance. When it works, it can suck the oil fume generated by cooking ingredients, intercept the grease in the oil fume on the air grid, and discharge the remaining oil fume outdoors to keep the kitchen air fresh. The suction area of range hoods on the market is fixed. When the amount of oil fume is too large, a smaller suction area cannot meet the usage requirements, resulting in some oil fume escaping. While range hoods with a larger suction area have an overall too large volume and are not suitable for kitchens with limited installation space.
[0003] Therefore, it is necessary to make further improvements to it.
Content of the Utility Model
[0004] The purpose of the utility model is to overcome the above problems. We provide a pull - type range hood with automatic opening and closing, which can increase the suction area when in use.
[0005] To achieve the above purpose, the utility model provides a pull - type range hood with automatic opening and closing, which includes a body, a first air grid, a second air grid and a driving mechanism. The first air grid is arranged on the air inlet at the bottom of the body. Inside the body, above the first air grid, there is a housing. The back of the housing is the air outlet and is communicated with the inside of the body. The second air grid is installed on the air inlet at the bottom of the housing. The housing can slide forward relative to the body, and the driving mechanism is used to drive the housing to slide.
[0006] In one or more embodiments, the left and right sides of the housing are slidably connected to the body through slide rails.
[0007] In one or more embodiments, the driving mechanism includes a driving motor, a screw rod and a sliding seat. The driving motor is used to drive the screw rod to rotate. The sliding seat is screwed to the screw rod and is fixedly connected to the housing through screws.
[0008] In one or more embodiments, a control panel is provided on the front side of the housing, and the control panel can be used to control the driving mechanism.
[0009] In one or more embodiments, a volute, a turbine and a turbine motor are arranged inside the body. The volute is provided with an air inlet grille and is communicated with the inside of the body. The turbine motor and the turbine are arranged inside the volute. The turbine motor is used to drive the turbine to rotate. The air outlet of the volute is arranged at the top of the body.
[0010] In one or more embodiments, a lighting lamp is arranged at the bottom of the body, and the lighting lamp is located on the left side or right side or rear side of the first air grid.
[0011] The effects of the present utility model compared with the background technology are as follows: The pull-out range hood has a second air net, and the second air net can be pushed out by a driving mechanism, increasing the suction area and reducing the escape of oil fumes.

Specific Embodiments
[0015] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.
[0016] Refer to the attached Figures 1-3 , this application provides a pull-out range hood with automatic opening and closing, which includes a body 1, a first air net 2, a second air net 3 and a driving mechanism. The first air net is arranged on the air inlet at the bottom of the body 1. Above the first air net inside the body, there is a housing 4. The back of the housing is the air outlet and is communicated with the inside of the body. The second air net 3 is installed on the air inlet at the bottom of the housing 4. The housing 4 can slide forward relative to the body 1. The driving mechanism is used to drive the housing to slide. Users can choose whether to push out and use the second air net according to needs. When the second air net is not pushed out, the oil fumes enter the body from the first air net; when the second air net is pushed out and used, the oil fumes can enter the body from the first air net and the second air net.
[0017] The left and right sides of the housing 4 are slidably connected to the body 1 through slide rails. Using slide rails to connect the housing and the body can ensure that the housing can smoothly slide in and out.
[0018] The driving mechanism includes a driving motor 5, a screw rod and a sliding seat 6. The driving motor is used to drive the screw rod to rotate. The sliding seat 6 is screwed to the screw rod and is fixedly connected to the housing 4 through screws. Specifically, when the driving motor drives the screw rod to rotate forward, the sliding seat moves forward along the screw rod to push out the housing; when the driving motor drives the screw rod to rotate reversely, the sliding seat moves backward along the screw rod to retract the housing into the body.
[0019] A control panel 7 is provided on the front side of the housing 4. The control panel can be used to control the driving mechanism. The control panel can specifically be a touch panel or a mechanical panel, and the control panel can also control the operation of the range hood.
[0020] A volute 8, a turbine and a turbine motor are arranged inside the body 1. The volute is provided with an air inlet grille 9 which communicates with the inside of the body. The turbine motor and the turbine are arranged inside the volute. The turbine motor is used to drive the turbine to rotate. The air outlet of the volute is arranged at the top of the body 1.
[0021] A lighting lamp 10 is arranged at the bottom of the body 1. The lighting lamp is located on the left side, right side or rear side of the first air net. The lighting lamp can provide illumination for the user to ensure that the user has sufficient light to cook food.
[0022] The above is only the preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the disclosure of the present utility model shall be included in the protection scope recorded in the claims.
