Description

Wall-hanging kitchen hood

The utility model relates to a kind of device of removing flue dust, particularly a kind of wall-hanging kitchen hood.

Kitchen hood is mainly used in removes the flue gas that produces in the kitchen, with the oil smoke that produces in time from indoor discharge, kitchen hood commonly used is hung above the kitchen sink, the about 800mm of distance pot face place, this type of kitchen hood is made up of casing, motor, fan blade, exhaust gases passes and windshield, wherein motor and fan blade are installed in the casing, its back is connected with exhaust gases passes, windshield is arranged in the outside, flue outlet place, the motor drives fan blade rotates, the fan blade motion sucks the oil smoke that produces in the pot in the casing, drains into outdoor through exhaust gases passes.There is following defective in this kitchen hood: the distance between air inlet of (1) casing and the pot face is excessive, be generally about 800mm, fan blade rotates can only make in the little space, air inlet below and forms negative pressuren zone, because the distance at pot face and casing air inlet place is far away, still have partly oil smoke before entering negative pressuren zone to around diffusion, stay many greasy dirts, the fume exhaust weak effect.(2) to improve the effect of fume exhaust, the casing that does not allow suspension type again is near the pot face, to avoid the collision of human body head and casing, often make the negative pressuren zone space enlargement by increasing motor horsepower and fan blade size, can improve the fume exhaust effect to a certain extent thus, but cause power consumption and noise to increase, its motor power (output) of suspension type kitchen hood commonly used is 100W～120W.(3) suspension type fume exhaust machine vibration is big, noise is high, and the difficult elimination of noise.

The purpose of this utility model is to provide a kind of wall-hanging kitchen hood, its casing is fixed on the body of wall of adjacent pot face, the air inlet place of casing is provided with blind window, and this blind window is formed the smoking chamber with casing, and motor and fan blade are installed in the exhaust gases passes near smoke outlet.Adopt this kitchen hood to have compact conformation, strong, the advantages such as vibration is little, noise is low, power consumptive province, cost is low, cleaning is convenient of fume exhaust ability.

Realization the utility model purpose is taked following technical measures:

1. casing is fixed on the body of wall of adjacent pot face, dwindled the distance between casing air inlet and the pot face significantly, the front end face of arranging simultaneously air inlet on the casing is a squint forward, and formation smoking chamber, during lampblack absorber work, the outside at casing air inlet place forms the negative pressuren zone that air pressure is lower, can drain into the oil smoke that is produced outdoor effectively.

2. motor and fan blade are installed in the exhaust gases passes near the gas outlet, perhaps be directly installed in the body of wall through hole, the motor of moving component and fan blade vibrate little away from the kitchen sink, noise is low, and this place produces little noise also along with flue gas passes together to outdoor.

3. be provided with the adjustable blind window of air-flow flux at the air inlet place, general gas range contains two burners, this lampblack absorber also correspondingly is provided with two air inlets, when if one of them air inlet does not have the oil smoke of eliminating task, then can close the blind window at this air inlet place, concentrate strength on taking out the oil smoke at another air inlet place.Because the oil smoke source is near negative pressuren zone with away from power-section, the integrated performance index of this kitchen hood obtains to significantly improve, only need to adopt a lower-powered motor and a fan blade can replace the function that original needs two cover power set could be realized simultaneously, power consumption is reduced to 40W～60W from 100W～120W.

Fig. 1 is the structural representation of wall-hanging kitchen hood.

Fig. 2 is the another kind of scheme of installation of wall-hanging kitchen hood.

Fig. 3 is the blind window structural representation.

Below in conjunction with description of drawings, be described in detail the design's particular content.

As shown in Figure 1 and Figure 2, a kind of wall-hanging suction lampblack absorber comprises casing 1, and is electronic Machine 2, fan blade 3, exhaust gases passes 4, windshield 5, motor 2 drives fan blade 3 and rotates flue gas Enter from the air inlet of casing 1, process exhaust gases passes 4 drains into outdoor, it is characterized in that casing 1 is solid Fix on the body of wall of adjacent pot face, the front end face 1A that arranges air inlet on the casing 1 is squint forward , the inclination angle α between this front end face 1A and the body of wall is 10 °～80 °, is positioned at front end face 1A On the air inlet place be provided with blind window 6, this blind window 6 forms the smoking chamber with casing 1, Motor 2 and fan blade 3 are installed in the exhaust gases passes 4 near smoke outlet. Inclination angle α Optimum value be 20 °～35 °.

As shown in Figure 3, blind window 6 adopts conventional small lever structure, by louver, small lever 6A and motion bar 6B form, and are used for control exhaust flux, its hinge and casing 1 front end face 1A it Between angle β be adjustable, the adjustable range of this angle β is 0 °～120 °.

With prior art relatively, the utlity model has following advantage:

1. compact conformation only adopts a cover power part.

2. negative pressuren zone is near the source of oil smoke, and the fume exhaust ability strengthens.

3. vibrate for a short time, noise is low, and power consumption is economized, and power consumption is reduced to 40W～60W from 100W～120W.

4. processing is simple, installs easily, and it is convenient to clean, and few with material, cost is low.

5. this machine adopts reversing motor, can be used for the conditioning chamber internal-external temperature difference in the summer of sweltering heat, has certain air conditioning function, is suitable for the bedroom simultaneously and uses.

Embodiment:
