Fume exhaust fan

Technical Field

The utility model relates to a for kitchen use household electrical appliances technical field specifically indicates a range hood.

Background

Range hood is the electrical apparatus that is essential in the kitchen at present, and is comparatively common and use more extensively to arrange oily smoke purification system in last.

At present, the upward-exhaust oil fume purification system is mainly divided into two types: a top-suction range hood and a near-suction range hood. The top-suction type range hood is more attractive, but the smoke inlet is higher, and the smoke suction effect is limited; compared with a top-suction range hood, the near-suction range hood has a lower smoke inlet, but is influenced by the appearance structure and the internal air duct structure of the near-suction range hood, and the existing near-suction range hood cannot better approach oil smoke, so that the oil smoke suction effect is limited to a great extent.

In order to improve the smoke collecting effect, the smoke purifying system is often provided with a smoke baffle at the air inlet. The larger the front and back width of the smoke baffle plate is, the better the smoke trapping effect is, but the smoke baffle plate is limited by the size of the body of the range hood, particularly for the turnable smoke baffle plate, the size of the smoke baffle plate needs to be matched with the size of the whole body and an air inlet, the smoke baffle plate is widened, the body on the lower side of the smoke baffle plate needs to be lengthened, the width of a smoke inlet needs to be increased, and the design requirement is difficult to meet.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1-2, the range hood of the present embodiment includes a housing 1 and a fan system 2 disposed in the housing 1. The lower part of the shell 1 is provided with a vertically extending smoke inlet cavity 11, the front side wall of the lower part of the shell 1 is provided with a smoke inlet 111 communicated with the smoke inlet cavity 11, the upper part of the shell 1 is provided with a smoke collecting cavity 12 communicated with the smoke inlet cavity 11, the smoke collecting cavity 12 extends forwards to form a mounting cavity 13 for mounting the fan system 2, it should be noted that the mounting cavity 13 is used for mounting the fan system 2, but the mounting position of the fan system 2 is not completely limited in the mounting cavity 13, and because the smoke collecting cavity 12 and the mounting cavity 13 are integrated, when the fan system 2 is mounted, the part of the fan system 2 can be positioned in the smoke collecting cavity 12 according to requirements. The air inlet 21 of the fan system 2 may be arranged in advance or in the rear direction, as long as it is communicated with the smoke collecting cavity 12, and the air outlet 22 of the fan system 2 is arranged upward. An oil collecting cup 4 with an upward opening is arranged at the lower edge of the shell 1, and the bottom of the smoke inlet cavity 11 is connected with the oil collecting cup 4. Because the smoke inlet cavity 11 at the lower part of the shell 1 vertically extends, the smoke inlet cavity 11 can be made thinner along the width in the front-back direction and can extend downwards to be sufficiently close to the cooker and a smoke generating source, so that the smoke can be quickly sucked into the smoke inlet cavity to be discharged upwards once being generated, and the smoke suction effect is improved.

In this embodiment, a smoke barrier 3 extending horizontally or obliquely forward is provided along the upper edge of the smoke inlet 111, and an extension plate 30 capable of moving back and forth relative to the smoke barrier 3 in a telescopic manner to change the width of the smoke barrier 3 is provided at the front side of the smoke barrier 3. The smoke barrier 3 is provided on the housing 1 so as to be capable of turning over for covering or opening the smoke inlet 111, and in the opened state, the smoke barrier 3 extends forward horizontally or obliquely.

The smoke baffle 3 can block the rising oil smoke, and simultaneously forms a negative pressure area with the smoke inlet cavity 11, so that the blocked oil smoke is collected and then discharged, and the whole oil smoke absorption effect of the range hood is improved. The extension plate 30 is arranged close to the back of the cigarette blocking plate 3, and the back of the cigarette blocking plate 3 is also provided with a driving piece 6 which can drive the extension plate 30 to stretch back and forth. The driving piece 6 is a push rod motor, a connecting part 301 extending from the back of the smoke baffle plate 3 is arranged at the rear edge of the extension plate 30, the push rod motor is arranged close to the rear edge of the smoke baffle plate 3, and the power output end 61 is connected with the connecting part 301. The push rod motor is simple in structure, convenient to assemble and good in driving stability.

The front edge of the extension plate 30 is provided with a bending edge 302 extending upwards, when the extension plate 30 retracts to the back of the cigarette blocking plate 3, the bending edge 302 abuts against the front edge of the cigarette blocking plate 3, and the upper edge of the bending edge 302 is aligned with the upper wall surface of the cigarette blocking plate 3. By adopting the structure, after the extension plate 30 is completely retracted, the extension plate and the smoke baffle 3 are visually integrated, the extension plate 30 is completely hidden, and the high aesthetic degree is kept.

The width of the smoke barrier 3 matches the width of the smoke inlet 111 when the extension board 30 is in the fully retracted state. When the smoke blocking plate 3 needs to close the smoke inlet 111, the smoke blocking plate 3 is matched with the smoke inlet 111 in size after the extension plate 30 is hidden, and the size of the whole machine and the size of the smoke inlet do not need to be changed in order to improve the smoke gathering effect.

In the present embodiment, a sensor 5 capable of detecting the concentration of the oil smoke is disposed in the smoke collection chamber 12, so as to control whether the extension plate 30 extends or retracts according to the concentration of the oil smoke. When the sensor 5 detects that the oil smoke concentration is higher, the extension plate 30 is driven by the push rod motor to extend out, so that the width of the smoke baffle plate 3 can be increased, the smoke gathering effect is improved, and the oil absorption effect is further improved; when the concentration of the oil smoke is small or the oil smoke is not used, the extension plate 3 can be retracted, and the size of the whole machine and the size design of a smoke inlet are not influenced.
