Embodiment Construction

[0016] An automatic closed range hood proposed by the present invention includes a casing, and the top of the casing is provided with a core device for extracting oil fumes - an exhaust fan, and the exhaust device communicates with the outside through a pipe.

[0017] The range hood proposed by the present invention also includes a movable panel 1 which is movably installed on the casing by means of slide rails. Such as figure 1 and figure 2 As shown, the two sides of the movable panel 1 are provided with inner slide rails 11, the front end of the housing is fixed with a front plate 2, and the corresponding positions on both sides of the front plate 2 are provided with the inner slide rails 11. After matching the outer slide rails 21 and the inner slide rails 11 installed on both sides of the movable panel 1 into the outer slide rails 21 , the movable panel 1 can slide on the front panel 2 along the outer slide rails 21 .

[0018] In order to realize the automatic opening a...

Abstract

The invention discloses a range hood capable of automatically closing down. The range hood capable of automatically closing down comprises a shell, an air draft device and a movable panel; a front plate is arranged at the front end of the shell; the movable panel is slidably arranged on the front plate through a sliding rail; a motor is arranged on the front plate; and the motor drives the movable panel to slide in the sliding rail through a gear and a tooth slot which are engaged with each other, so a function of opening and closing the movable panel can be realized. When the range hood does not work, the movable panel is covered on an air draft opening for extracting lampblacks; when the range hood works, the air draft outlet is uncovered; therefore, outdoor insects and foreign substances can be prevented from entering the room from a ventilation opening; and when the range hood is not used, the air draft opening is covered so as to prevent indoor winged insects from being adhered to the grids of the air draft opening. The range hood capable of automatically closing down has a rational structure, is reliable in transmission, is convenient to control, and can run stably, and cannot influence the working efficiency of an exhaust fan during use; and as the structure is unique and the appearance is novel, the level of the range hood is increased.

Description

technical field [0001] The invention relates to a range hood, in particular to an automatic closing range hood. Background technique [0002] Commonly used air extraction equipment such as exhaust fan and range hood, etc., use the exhaust fan to suck away the unclean air in the room. However, since the exhaust port is connected to the indoor and outdoor, when the range hood is not working, the outdoor insects will , Floating objects in the air, rainwater and other substances can easily enter the room through the air outlet, causing troubles to households. Although some range hoods have shutters installed on the outdoor side, when the exhaust fan is working, the shutters are pushed open by wind force, and when the exhaust fan stops, they are reset and closed by their own gravity to close the air outlet, but the design of this shutter It needs to be pushed by wind to open, which reduces the efficiency of the exhaust fan. In addition, when the blinds are oily, it is easy to af...
