Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
Shown in Fig. 1 to Fig. 5, the preferred embodiment of the present invention, a kind of complete embedding range hood, including range hood main body
1, the main smoke collecting chamber 2 with main smoking port and with auxiliary smoking port auxiliary smoke collecting chamber 3, the main smoke collecting chamber 2 can on move down
It is arranged dynamicly at the back of the range hood main body 1, and can be stretched out from the bottom of the range hood main body 1, forms side and inhale
Formula structure, the main smoke collecting chamber 2 after stretching are connected to the negative pressure cavity of range hood main body 1；The setting of auxiliary smoke collecting chamber 3 exists
Top suction type structure, the negative pressure cavity of the auxiliary smoke collecting chamber 3 and range hood main body 1 are formed on the bottom of the range hood main body 1
Connection.As a result, by the combination of main smoke collecting chamber 2 and auxiliary smoke collecting chamber 3, auxiliary smoke collecting chamber 3 has shared 30%~40% smoke evacuation
Ability.
Further include stabilier 4 on the basis of above-mentioned full embedding type range hood, the stabilier 4 can turn in the present embodiment
It is opened and closed dynamicly in the bottom of the auxiliary smoke collecting chamber 3, the stabilier 4 and the bottom of the auxiliary smoke collecting chamber 3 are formed by out
It is 0 degree~150 degree to close angle [alpha].
To ensure the promotion of complete machine smoking effect, illustratively, the auxiliary smoke collecting chamber 3 is integrated drawing and forming, is in loudspeaker
Shape, stretching depth are up to 60mm.Such design, can promote auxiliary smoking port holds together cigarette ability, realizes that deep chamber is big
The effect of suction.But due to assisting smoking port apart from cookware apart from farther out, negative pressuren zone loss is larger, therefore smoking port is assisted to be in
When a large amount of oil smoke aggregations, it can not accomplish to inhale speed row wink；Thus the effect of stabilier 4 is it is clear that when stabilier 4 is opened,
It is formed in α angular regions together " natural cover for defense ", the rapid oil smoke assembled and can not instantaneously siphoned away, at this time by firmly
" gathering " in α angular regions, to auxiliary smoking port there are the time of " panting ", stabilier 4 can reduce turbulent flow in air-flow and
Sinuous flow phenomenon after the oil smoke to be escaped encounters stabilier 4, is involved in the deep intracavitary of auxiliary smoke collecting chamber 3, is then sucked away.
Preferably to explain the effect of stabilier 4, to full embedding type range hood, whether there is or not 4 states of stabilier to carry out effect pair
Than.The smoking port of full embedding type range hood includes mainly main smoking port I, auxiliary smoking port II, due to the full embedding type cigarette of the first generation
Machine only has main smoking port, and since mounting distance is higher, whole smoking effect is undesirable, therefore auxiliary smoking is increased in the second generation
Mouthful, but the quick-fried at home under cooking environments is instantaneous, and it is still undesirable to the suction of oil smoke；Therefore the selection optimized in the present invention
Stabilier 4, as shown in the left figure in Fig. 5, in the case of no stabilier 4, the oil smoke overwhelming majority steeply risen is by main suction
Mouth siphons away, and part is not sucked away oil smoke and is pulled up to auxiliary smoking port by negative pressuren zone, but since auxiliary smoking port is apart from pot
Farther out, negative pressure loss is larger for tool, therefore can see the oil smoke at a has the tendency that escape, and is colliding auxiliary smoking port bottom
Due to have no occluder when portion, finally escaped by b；As shown in the right figure in Fig. 5, the smoke machine of stabilier 4, the oil at a are carried
Cigarette can be by critical point at b, due to the effect of stabilier 4, and the oil smoke to be escaped is lived by " gear ", negative pressuren zone is involved in again, by c
Place is finally sucked away.
It can be seen that by the setting of stabilier 4, air curtain, the oil smoke instantaneously generated to quick-fried can be formed in user side
Play the role of gathering, current stabilization, forces oil smoke to be gathered at auxiliary smoking port etc. to be discharged, reduce turbulent flow and sinuous flow in air-flow
Phenomenon prevents fumes escaping, forms smooth-going air-flow and improves cigarette effect simultaneously.
