Abstract
The utility model discloses a blade-free jetting type range hood flow disturbance and suck-back prevention device, which comprises a flow disturbing hood arranged above a circular cyclone accelerator, the flow disturbing hood adopts a circular table-shaped structure, and a helical groove is formed in the inner wall of the circular table-shaped flow disturbing hood; a circular oil collection tank is arranged on the upper end surface of the cyclone accelerator and positioned on the outer side of an air outlet; the bottom end of the helical groove is communicated with the circular oil collection tank. The flow disturbing hood can accommodate air in the circular table-shaped flow disturbing hood, the air and oil smoke are blown away from bottom to top in one direction, so as to well prevent flow disturbance; liquid oil drops formed by oil smoke condensation can be smoothly gathered in the oil collection tank along the groove in the flow disturbing hood, and an air outlet in the cyclone accelerator is prevented from being blocked, so that suck-back is avoided.
Description
Technical field
The utility model relates to cooking apparatus field, particularly a kind of auxiliary equipment without the jet-propelled lampblack absorber of flabellum.
Background technology
Along with the raising of people's living standard, lampblack absorber has become one of requisite cooking apparatus in life.In various lampblack absorber, be exactly wherein a kind of without the jet-propelled lampblack absorber of flabellum.
Without flabellum jet-propelled range hood, comprise cyclone accelerator, turbocompressor, air induction conduit, air admission hole, the conduit of supplying gas, discharge chamber, speed setting controller, lamp dimmer and door.It is the technology of utilizing jet plane engine and vehicle turbine supercharging, in body with two 45W brushless electric machines by air intake compressor inside, air via cyclone accelerator annular epipharynx around and accelerate after, upwards blow out through cyclone accelerator air outlet slit with certain speed, ascending air drives near air fan head to enter fan head thereupon, and produce negative pressure below cyclone accelerator, air pressure under annulus can reduce, cause the more air in below to add with equilibrium air pressure, air quantity is exaggerated.By air compressor supercharging, and discharge with certain speed, finally form one continual air-flow and upwards discharge, and below produce negative pressure and reach smoke discharging effect.
But, also there is a very large problem without the jet-propelled lampblack absorber of flabellum, be exactly that oil smoke is from the ejection of cyclone accelerator, one side is due to the irregular movement of gas and olesome, can be at the inner flow-disturbing that produces of lampblack absorber, air can not be discharged from the outlet of top oil smoke with consistent direction with oil smoke, does random motion in chamber, and the pumping efficiency of lampblack absorber is had a strong impact on.On the other hand, lower with respect to the temperature of oil smoke while accelerating mouth ejection due to air from cyclone, oil smoke can be condensed into oil droplet and flow down from inwall, because cyclone accelerator air port is an annular finedraw, so easily blocked by oil droplet, produce suck-back, lampblack absorber cannot be worked.
Summary of the invention
The utility model technical issues that need to address are to provide a kind of being applied in without the turbulent-flow-prevention suck-back device in flabellum lampblack absorber, solve flow-disturbing and suck-back problem without the jet-propelled lampblack absorber of flabellum.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
Without the jet-propelled lampblack absorber turbulent-flow-prevention of flabellum suck-back device, comprise the flow disturbing cover that is arranged on annular cyclone accelerator top, described flow disturbing cover is truncated cone-shaped structure, the inwall of truncated cone-shaped flow disturbing cover is provided with spiral groove; The outside that is positioned at air outlet slit on the upper surface of described cyclone accelerator is provided with circular oil trap; The bottom of described spiral groove is connected with circular oil trap.
Owing to having adopted above technical scheme, the obtained technological progress of the utility model is as follows.
The flow disturbing cover of the utility model setting can be included gas within the scope of this truncated cone-shaped flow disturbing cover, makes air and oil smoke unify direction and blows out and drain from bottom to top, has prevented well flow-disturbing.On the other hand, the liquid oil droplet that oil smoke condensation forms can converge in the oil trap on cyclone accelerator by the spiral groove on flow disturbing cover, and oil droplet just can not flow to the air outlet slit on cyclone accelerator like this, has prevented the generation of obstruction and suck-back phenomenon.
Brief description of the drawings
Fig. 1 is cutaway view of the present utility model.
Wherein: 1. cyclone accelerator, 11. air outlet slits, 12. oil traps, 2. flow disturbing cover, 21. grooves.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
A kind of without the jet-propelled lampblack absorber turbulent-flow-prevention of flabellum suck-back device, its structure as shown in Figure 1, comprises flow disturbing cover 2 and cyclone accelerator 1, and described flow disturbing cover 2 is truncated cone-shaped structure, and truncated cone-shaped flow disturbing cover inwall is provided with spiral groove 21; The outside that is positioned at air outlet slit 11 on the upper surface of described cyclone accelerator is provided with concentric with it circular oil trap 12; Spiral groove is connected with circular oil trap.
When without the jet-propelled lampblack absorber work of flabellum, two 45W brushless electric machines are by air intake compressor inside, air via cyclone accelerator annular epipharynx around and accelerate after, upwards blow out through cyclone accelerator air outlet slit with certain speed, ascending air drives near air fan head to enter fan head thereupon, and produces negative pressure below cyclone accelerator, and the air pressure under annulus can reduce, cause the more air in below to add with equilibrium air pressure, air quantity is exaggerated.By air compressor supercharging, and discharge with certain speed, finally form one continual air-flow and upwards discharge.In this process, flow disturbing cover can be included gas within the scope of this truncated cone-shaped flow disturbing cover, makes the same direction of air and oil smoke blow out and drain from bottom to top, has prevented well flow-disturbing.The liquid oil droplet that oil smoke condensation forms can slowly flow down the oil trap finally converging on cyclone accelerator by the spiral groove on flow disturbing cover, and oil droplet will flow in the air outlet slit on cyclone accelerator like this, has prevented the generation of obstruction and suck-back phenomenon.
Claims (1)
1. without the jet-propelled lampblack absorber turbulent-flow-prevention of flabellum suck-back device, it is characterized in that: comprise the flow disturbing cover (2) that is arranged on annular cyclone accelerator (1) top, described flow disturbing cover is truncated cone-shaped structure, and the inwall of truncated cone-shaped flow disturbing cover is provided with spiral groove (21); The outside that is positioned at air outlet slit (11) on the upper surface of described cyclone accelerator is provided with circular oil trap (12); The bottom of described spiral groove is connected with circular oil trap.
