Description

Fume exhaust fan

Technical Field

The utility model relates to a switch, especially a range hood.

Background

The range hood has become one of the indispensable kitchen household electrical appliances in modern families. The range hood works by utilizing the fluid dynamics principle, sucks and exhausts oil smoke through a centrifugal fan arranged in the range hood, and filters partial grease particles by using a filter screen. The centrifugal fan comprises a volute, an impeller arranged in the volute and a motor driving the impeller to rotate. When the impeller rotates, negative pressure suction is generated in the center of the fan, oil smoke below the range hood is sucked into the fan, accelerated by the fan and then collected and guided by the volute to be discharged out of a room.

The side-draft range hood absorbs most of oil smoke close to a cooking bench in an arc form by using a vortex air pressure principle, so that adverse effects on human health can be reduced, and the suction effect of a power source is basically not reduced because the power source is close to the cooking bench.

The whole appearance of the side-draft range hood is generally a two-section type or three-section type structure, and in order to improve the smoke gathering effect, a smoke baffle plate is usually arranged at the air inlet of the side-draft range hood, and the smoke baffle plate is in an open state when the range hood works, so that the effect of blocking and guiding the oil smoke is achieved. The anti-return air mechanism of the range hood disclosed in the chinese patent with the application number of 201510201000.2 comprises an oil receiving bottom groove, a range hood body, a baffle, an opening and closing panel, a flue casing and a smoke baffle, wherein the opening and closing panel is connected and arranged on the range hood body through a rotating shaft.

However, when the smoke barrier is opened, a gap is formed between the end of the smoke barrier connected with the casing and the casing, and the gap has the following problems: 1) if the gap is too large, the oil smoke cannot enter the air inlet in time, and the oil smoke escapes from the gap; 2) if the gap is too small, the smoke baffle is in hard contact with the front panel when being opened, and the panel glass can be damaged; when the gap is too small, the fan can vibrate during operation, so that abnormal sound is generated between the smoke baffle plate and the front panel.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions.

In the description of the present invention, it is to be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in a generic and descriptive sense only and not for purposes of limitation, as the disclosed embodiments of the invention may be oriented in different directions and the directional terms are intended to be illustrative and should not be construed as limiting, such as "upper" and "lower" are not necessarily limited to directions opposite to or coincident with the direction of gravity. Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Referring to fig. 1 to 3, a side-draft range hood, which comprises a housing 1, wherein the front side of the housing 1 is open and is gradually inclined backwards from top to bottom, and an upper panel 2 and a lower panel assembly 3 are respectively arranged at the open of the housing 1 from top to bottom. The front side of the shell 1 and the position corresponding to the lower panel assembly 3 form an air inlet 11, and the air inlet 11 is arranged below the upper panel 2. The upper panel 2 and the housing 1 are fixedly disposed, and the lower panel assembly 3 can translate and rotate relative to the housing 1, so as to open or close the air inlet 11, and when the lower panel assembly 3 is closed, the lower panel assembly 3 is in a first position, and when the lower panel assembly 3 is opened, the lower panel assembly 3 is in a second position, and the lower panel assembly 3 is located at the front side of the upper panel 2.

The lower panel assembly 3 comprises a lower panel 31, a first baffle 32, a second baffle 33 and a third baffle 34, wherein the shape and size of the lower panel 31 correspond to the air inlet 11, the first baffle 32 extends from the bottom of the lower panel 31 to the inside of the housing 1, the second baffle 33 has two baffles which are respectively arranged at two sides of the first baffle 32, the third baffle 34 is connected between the rear sides of the first baffle 32 and the second baffle 33, the first baffle 32, the second baffle 33 and the third baffle 34 enclose a cover body with a triangular longitudinal section, and the cover body is connected and fixed with the lower panel 31 so that the lower panel assembly 3 forms a relatively closed space. The lower panel assembly 3 can be in an initial state of closing the air inlet 11, and can also be driven by the moving mechanism to gradually move upwards and rotate, so that the air inlet 11 is opened, and the range hood enters an oil smoke absorption working state. The motion mechanism can adopt the existing technology, such as an electric push rod (motor) and a connecting rod mechanism assembly.

Referring to fig. 4 and 5, after the lower panel assembly 3 is opened, the third baffle 34 of the lower panel assembly 3 is parallel to the upper panel 2, a gap X is formed between the third baffle 34 and the upper panel 2, the distance of the gap X is X, and the value range of X is 2-4 mm. The existence of this clearance X has avoided the hard contact between panel assembly 3 and the top panel 2 down, plays the effect of protection top panel 2, avoids the different sound of shake between panel assembly 3 and the top panel 2 down simultaneously when the fan operates, has reduced the noise.

In addition, after the lower panel assembly 3 is opened, the first baffle 32 plays a role of blocking smoke and guiding flow, and is located below the lower end of the upper panel 2, and the vertical distance between the first baffle 32 and the lower end of the upper panel 2 is h. The oil smoke will enter the air inlet 11 under the guiding action of the first baffle 32, so that the oil smoke will not move upwards through the gap X between the lower panel assembly 3 and the upper panel 2, thereby effectively solving the problem of oil smoke escape.
