Below with reference to Fig. 1-Figure 13 description according to the air intake assembly of the kitchen ventilator 200 of the utility model first aspect embodiment 100。

It include collection cigarette according to the air intake assembly 100 of the kitchen ventilator 200 of the utility model embodiment with reference to shown in Fig. 1-Figure 13 Cover 1 and cold plate 2.

Smoke collecting chamber 11 is limited in exhaust fume collecting hood 1, smoke collecting chamber 11 has guide face 111 and air inlet 112, needs to illustrate It is that kitchen ventilator 200 further includes casing 201 and wind wheel component 202, and flue 2011 is formed in casing 201, and air intake assembly 100 is set In the lower section of casing 201, air inlet 112 is connected to flue 2011, wind wheel component 202 be set to flue 2011 in drive flue gas by Air inlet 112 flows in flue 2011, and flue 2011 also has the smoke outlet 2012 for being suitable for being connected to external environment, into flue Flue gas in 2011 is expelled in external environment by smoke outlet 2012.

Specifically, when kitchen ventilator 200 works, wind wheel component 202 operates at air inlet 112 formation negative pressure, when culinary art The oil smoke of generation enters in smoke collecting chamber 11, is entered in flue 2011 under the guiding of guide face 111 by air inlet 112.Wherein, The inner surface of smoke collecting chamber 11 can be configured to intermediate concave inward structure high, periphery is low, and the inner surface of smoke collecting chamber 11 constitutes the guide face 111, to assist sucking flue gas, the effect realized tobacco control, hold together cigarette.

Cold plate 2 is set in smoke collecting chamber 11, and the corresponding air inlet 112 of cold plate 2 is arranged and is located at the lower section of air inlet 112, Cold plate 2 is spaced apart to guarantee that air inlet 112 is not blocked with the inner surface of smoke collecting chamber 11.Cold plate 2 plays condensation oil smoke, bears Pressure extends out and accepts the effect of oil liquid.

Specifically, the flue gas generated when culinary art is impinged upon first on cold plate 2, and the oil smoke in flue gas coagulates on cold plate 2 Knot forms oil droplet and is attached on cold plate 2, while obstruction of the flue gas through cold plate 2 is spread to 2 periphery of cold plate, and periphery is born Pressure can by the flue gas of diffusion suck flue 2011 in, specifically, through the condensed flue gas of cold plate 2 pass sequentially through cold plate 2 with Gap 12 and air inlet 112 between the inner surface of smoke collecting chamber 11 enter inside smoke machine.

Preferably, the area of cold plate 2 is greater than the area of air inlet 112, thus not only makes connecing for cold plate 2 and flue gas Touching is more abundant, and oil smoke condensation effect is good；And it can effectively expand 112 negative pressure distributed areas of air inlet, to promote smoke machine Smoking effect；In addition cold plate 2 can more broadly accept the oil droplet fallen inside casing 201, preferably avoid smoke machine The oil droplet of internal condensation is directly dropped on hearth, to promote user experience.

It is fallen inside the casing 201 accepted on the oil liquid and cold plate 2 on cold plate 2 it is to be appreciated that condensing in Oil droplet needs are collected and are dropped on hearth to avoid it, and therefore, kitchen ventilator 200 further includes lubricating cup 203, on cold plate 2 Oil liquid is collected into lubricating cup 203.In order to enable the oil liquid on cold plate 2 swimmingly to flow to lubricating cup 203, usually by cold plate 2 are obliquely installed in the up-down direction, and lubricating cup 203 is set to the lower side of cold plate 2, and the oil liquid on cold plate 2 is made in gravity It is guided in lubricating cup 203 with the lower inclined surface along cold plate 2.

Specifically, in the present invention, cold plate 2 include first end relative to each other along 21 and second end along 22, it is cold For solidifying plate 2 by first end, inclination extends upwards on 21 direction towards second end along 22, such second end is higher than first along 22 End is along 21, therefore the oil liquid on cold plate 2 will be flowed towards first end along 21 along the inclined surface of cold plate 2 under the effect of gravity Dynamic, lubricating cup 203 is set to first end at 21, will be collected to oil liquid of the first end at 21 and collect in lubricating cup 203.

Optionally, first end can be the front end edge of cold plate 2 or rear end edge along 21, when first end is cold plate 2 along 21 Front end along when, second end along 22 be cold plate 2 rear end edge, cold plate 2 tilts upwards on direction from the front to the back at this time Extend, i.e., the front end of cold plate 2 is low at this time, rear end is high, and lubricating cup 203 is set to the front end of cold plate 2 at this time；When first end is along 21 The rear end of cold plate 2 along when, second end along 22 be cold plate 2 front end edge, at this time cold plate 2 on direction from the front to the back to Upper inclination extends (as shown in Fig. 1-Fig. 4), i.e., the rear end of cold plate 2 is low at this time, front end is high, and lubricating cup 203 is set to condensation at this time The rear end of plate 2.

Or optionally, first end can be the left end edge of cold plate 2 or right end edge along 21, when first end is condensation along 21 The left end of plate 2 along when, second end along 22 be cold plate 2 right end edge, cold plate 2 is on direction from left to right to updip at this time Tiltedly extend, i.e., the right end of cold plate 2 is high at this time, left end is low, and lubricating cup 203 is set to the left end of cold plate 2 at this time；When first end is along 21 For right end along when, second end along 22 be left end edge, at this time cold plate 2 on direction from right to left upwards inclination extend, i.e., this When cold plate 2 left end is high, right end is low, lubricating cup 203 is set to the right end of cold plate 2 at this time.
