Problems solved by technology

Although the patent can realize automatic opening and closing of the door panel, since the motor drives the connecting rod in a straight-line reciprocating manner, the swing angle of the connecting rod is too narrow, resulting in a too small opening angle of the door panel, which affects the air suction port. Suction efficiency

Embodiment Construction

[0019] The present invention is further described in conjunction with the following examples.

[0020] Such as figure 1 As shown, the range hood main body 1 is provided with a rotatable door panel 2 through the hinge structure 4 at the air suction port 3. When oil fume needs to be sucked, the hinge structure 4 pushes the door panel 2 away from the air suction port 3, and the air suction port 3 is no longer blocked. , at this time, the range hood can work to absorb oil fume. When there is no need to absorb oil fume, the hinge structure 4 pushes the door panel 2 to cover the air suction port 3 and blocks the air suction port to prevent the air suction port from being exposed.

[0021] The hinge structure 4 will be described in detail below.

[0022] Such as Figure 2 to Figure 5 As shown, the hinge structure 4 includes a hinge base 41, a bowed hinge arm 45, a rocking arm 43, a connecting rod 44 and a driving device 42 fixed on the hinge base 41, one end of the rocking arm 43 i...

Abstract

The invention relates to the field of range hoods, in particular to a hinge structure for an opening and closing door sheet of a range hood. The hinge structure is characterized in that a driving device is used for swinging a rocker arm so that a connecting rod can control the swinging angle of an arched hinge arm through a swinging mode, namely, the opening angle of the door sheet is controlled;different from the prior art that the connecting rod is driven by a push rod in a linear reciprocating mode, the hinge structure adopts the mode that the rocker arm and the connecting rod swing cooperatively so as to increase the swinging angle of the arched hinge arm, and therefore the opening angle of the door sheet is increased; and the rocker arm is additionally arranged between the driving device and the connecting rod, so that the components are matched with one another more stably, and the rotating noise is reduced.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a hinge structure for opening and closing door panels of range hoods. Background technique [0002] Range hoods are mainly used in the kitchen to absorb oily fumes during cooking to avoid oily fumes from polluting the kitchen. Therefore, a range hood is generally provided with a suction port for absorbing oily fumes. [0003] In order to prevent the exposure of the air suction port from affecting the appearance of the range hood, some range hoods that can block the suction port have appeared on the market. These range hoods are provided with a rotatable door panel at the suction port. When cooking fumes, you can turn the door panel away from the suction port, and the suction port will no longer be blocked. At this time, the range hood can work to absorb the fume. The suction port is exposed. [0004] However, traditional door panels need to be opened manually, which is time-consuming...
