Abstract

The invention discloses an air amplified range hood, which is characterized in that: an end face wall of an exhaust port of a standard air amplifier body is provided with a ring oil groove, a through oil hole is arranged between an end face of an air suction port and an oil groove, the outer wall of an air suction port section is provided with a thread, an air inlet hole is arranged outside one end section of an air inlet pipe in a threaded arrangement mode, the other end section of the air inlet pipe is arranged in one end section of a handle pipe sleeve in a threaded arrangement mode, the other end section of the handle pipe sleeve is arranged outside one end section of an air delivery pipe in a threaded arrangement mode, the other end section of the air delivery pipe is communicated with an air compressor, dividing walls are respectively arranged among the oil groove (and the oil hole) and an original ring cavity, an annular gap and an air inlet hole of the body, and parts of the range hood are arranged in the body. According to the range hood disclosed by the invention, as an air amplifier body with an oil groove and an oil hole is added for replacing a motor and an impeller below a smoke exhaust pipe, tobacco tar on the inner wall of the smoke exhaust pipe drips into the oil groove, flows out of the oil hole and then falls into an oil collecting box, spatial tobacco tar directly falls into the oil collecting box, so that a situation that tobacco tar blocks the air gaps is avoided, a defect that meals are polluted through centrifugal oil splashing is eliminated, and a defect that oil sludge is generated on impellers and the like does not exist, therefore, the range hood specially has an advantage of easy cleaning.

Description

Air amplifying type smoke exhaust ventilator

Technical field

The invention relates to the invention of air amplifying type smoke exhaust ventilator.

Background technology

Existing smoke exhaust ventilator; Motor and wind wheel are arranged on the smoke exhaust pipe below; Be adsorbed on the oil stain of impeller, motor, wind chamber, smoke exhaust pipe, when start, have suitable deal to be got rid of into the dish pot, directly contaminated food products by centrifugal force; The tobacco tar that has accumulated in the smoke exhaust pipe lower end is almost all fallen the surface in impeller, wind chamber after shutdown, form grease.Remove this also efficient low, noise big, difficult cleaning.

Summary of the invention

Content of the present invention: air amplifying type smoke exhaust ventilator contains air amplifier, air compressor machine, air feed pipe fitting, smoke exhaust ventilator spare.Promptly; The exhaust port side of normal air amplifier body faces the wall and meditates to establish newly has annular oil groove, and increase has straight-through oilhole between air entry end face to the oil groove, and the increase of air entry section outer wall has screw thread; The air admission hole thread bush places outside the end section of air inlet pipe; The other end section thread bush of air inlet pipe places in the end section of handle pipe box, and the other end section thread bush of handle pipe box places outside the end section of appendix, and the other end section of appendix is communicated with air compressor machine; Between the original toroidal cavity of oil groove and oilhole and body, annulus gap, the air admission hole partition is arranged all, smoke exhaust ventilator spare is assemblied in body.

Benefit of the present invention: this machine has the air amplifier body of oil groove and oilhole with increase; The motor and the impeller that replace the smoke exhaust pipe below; Pressure-air when exhaust outlet is gone out, aspirates the oil smoke gas under the air entry from the air gap of body strongly, and aspiration several times even number decuple air consumption; Eliminate centrifugal drawback of getting rid of the oil pollution food, do not had the defective of generation greases such as impeller; The unique advantage of being convenient to clean.

Among Fig. 1 to Fig. 5: oil groove-1, body-2, oilhole-3, cavity-4, air gap-5, air admission hole-6, oil collection box-7, barrier tube-8, overhead guard shell-91, side case-92, top tube-10, air inlet pipe-11, handle pipe box-12, appendix-13, smoke exhaust pipe-14, air compressor machine-15.

Specific embodiment

Embodiment one: like Fig. 1, Fig. 2, shown in Figure 4; The increase of facing the wall and meditating of the exhaust port side of normal air amplifier body-2 has annular oil groove-1 (can car or mill processing); Increase has straight-through oilhole-3 (can bore or mill processing) between air entry end face to the oil groove-1; Air entry section outer wall increase has screw thread (can Vehicle Processing); The air admission hole thread bush places an end section outer (so-called screw thread is nested with, and promptly is that inwall has screw thread and threaded two parts of outer wall to be nested, to plug into screwed) of air inlet pipe-11, and the other end section thread bush of air inlet pipe-11 places in the end section of handle pipe box-13; The other end section thread bush of handle pipe box-13 places outside the end section of appendix-12; The other end section of appendix-12 is passed porthole and is communicated with and is installed in outdoor air compressor machine-15, between oil groove-1 and oilhole-3 and body-2 original toroidal cavity-4, annulus gap-5, the air admission hole-6 partition is arranged all, is not communicated with each other, and the smoke exhaust ventilator spare of body-2 assembling is that the threaded oil collection box of smoke exhaust pipe 14, top cylinder inside and outside wall and the threaded barrier tube-8 of following drum outer wall, inwall 9, apical pore are fixedly arranged in the case-91 that internal thread pushes up a bottom outer wall of tins-10; The exhaust outlet section of body-2 is placed in the end section of smoke exhaust pipe-14; The top cylinder inner thread of air entry section outer wall and barrier tube-8 is nested with, and the wall screw thread is nested with within the last drum outer wall of barrier tube-8 and the top tube-10, and the wall screw thread is nested with within following drum outer wall and the oil collection box-7; The other end section of smoke exhaust pipe-14 is stretched out outdoor, and wall is fixedly arranged in the apical pore of overhead guard shell-91 outside tube-10 bottoms, top.

This machine design feature: with increase the air amplifier body of oil groove and oilhole is arranged, replace the motor and the impeller of smoke exhaust pipe below; Wall attachment effect: pressure-air when exhaust outlet is gone out, aspirates the oil smoke gas under the air entry from the air gap of body strongly, and aspiration several times even number decuple air consumption; The antiscale characteristic: the inwall tobacco tar of smoke exhaust pipe splashes into oil groove outflow oilhole and falls into oil collection box, and the space tobacco tar directly falls into oil collection box, avoids tobacco tar to stop up air gap, has eliminated centrifugal drawback of getting rid of the oil pollution food, does not have the defective of generation greases such as impeller; Clean simple and easy: screw the handle pipe box earlier and unload air inlet pipe; Screw out the barrier tube again and unload body and case; The unique advantage of being convenient to clean: de-noising characteristics: isolate air compressor machine and air amplifier body with body of wall, reduce the noise nuisance that the user receives to greatest extent.

Embodiment two: like Fig. 1, Fig. 3, shown in Figure 5, wall is fixedly arranged in the apical pore of side case-92 outside tube-10 bottoms, top, and the other end section of appendix-12 is passed the platen hole and is communicated with the air compressor machine-15 that is installed in the cabinet, and other are identical with embodiment one.

Present patent application requires the scope of protection also to comprise: embodiment one makes into air compressor machine is installed in the cabinet, and embodiment two changes into wall air compressor machine is installed outward, and embodiment one and embodiment two make on the indoor wall or on the sales counter air compressor machine to be installed; Appendix installs mechanical valve or magnetic valve additional; The change of the angle of the related barrier tube of air amplifier body and case and vertical.
