Abstract

The utility model relates to a two air intake range hoods with inside and outside flip, including main air intake, interior flip, assist the air intake, outer flip, the switch, the light, the fuselage turns up the support, the turning over counter roll, the oil cup. Compared with the similar products, the range hood has the following remarkable advantages: when cooking, the inward turning cover is inclined inwards to play a role of a guide plate, and the resistance of oil smoke entering the air inlet is obviously reduced, so that the suction force of the range hood on the oil smoke is obviously enhanced; meanwhile, as the auxiliary air inlet and the outer turnover cover are additionally arranged, the small part of the oil smoke which does not enter the main air inlet and flows upwards is covered by the outer turnover cover, so that the atmospheric pressure is pressed into the auxiliary air inlet to achieve secondary emission, and the smoke exhaust effect is ideal. And when this product was out of work at ordinary times, because of flip's closing, kept apart and outwards gived off at the greasy dirt peculiar smell of fuselage inner chamber, let the kitchen air cleaner, be favorable to that people's is healthy.

Description

Double air inlet fume exhaust fan with inner and outer turnover cover

One, the technical field

The utility model relates to a double-air-inlet range hood with an inner flip cover and an outer flip cover.

Second, background Art

At present, the domestic and foreign range hood industries are the same as other fields, and the competition for customers to expand the market is intensified. Through the knowledge of after-sales service personnel, a relatively large group tends to other products because the smoke exhaust effect is not ideal, rather than abandoning the selection of one product due to the price and style. Therefore, in order to strive for the part of consumer groups as much as possible, a double-air-inlet range hood with an inner turnover cover is developed, the outer turnover cover originally covering the air inlet is replaced by the inner turnover cover, and experiments prove that the inner turnover cover is inclined inwards to play a role of a guide plate when the double-air-inlet range hood is opened, so that the resistance of oil smoke entering the air inlet is obviously reduced, and the suction force of the range hood on the oil smoke is obviously enhanced. And because a structure with double air inlets is adopted, the oil smoke is discharged twice: the oil smoke which flows upwards and flows over the main air inlet is pressed into the auxiliary air inlet by the atmospheric pressure again for removing, and the ideal effect of smoke discharge is achieved; and when not working at ordinary times, because of the closure of flip, kept apart and remained the greasy dirt peculiar smell of inner chamber and outwards gived off, let the kitchen air cleaner, be favorable to that people's is healthy.

Third, the invention

The utility model discloses to the unsatisfactory problem of improvement exhaust fume effect, invent a two air intake range hood with interior outer flip, its technical scheme is: the air conditioner comprises a main air inlet, an inner turnover cover, an auxiliary air inlet, an outer turnover cover, a switch, a lighting lamp, a machine body, an outward turnover support, an inward turnover support shaft and an oil cup. It is characterized by that the front of vertical portion of the cooker hood body is equipped with a main air inlet, its front is equipped with an internal turnover cover, the lower edge of said internal turnover cover is connected on a supporting shaft (driven by a small DC motor, not shown), and two ends of said supporting shaft are fixed on two sides of bottom portion of the cooker hood body. The front of the bottom surface of the upper part of the machine body is provided with an auxiliary air inlet, an outer flip cover is arranged in front of the auxiliary air inlet, the left and right bottoms of the outer flip cover are fixedly connected on a support, and the support is fixed on two sides of the auxiliary air inlet. The middle of the auxiliary air inlet is provided with an illuminating lamp, and the upper front panel is provided with a switch. After the range hood is designed, the range hood has the following remarkable advantages:

when cooking, the switch of the range hood is turned on, the inner flip cover tilts inwards, the main air inlet is exposed, the outer flip cover turns outwards, and the auxiliary air inlet is exposed; the cooking range is ignited, the cooking range oil smoke rises, the inner turnover cover is guided to flow down and is sucked into the smoke machine through the main air inlet, and a small part of the oil smoke flows upwards through the main turnover cover and is covered by the auxiliary turnover cover on the main turnover cover to enter the auxiliary air inlet to be discharged outwards. Because the inner turnover cover on the main air inlet of the range hood plays a role in guiding cooking oil smoke, the suction force of the range hood is enhanced, and the outer turnover cover of the auxiliary air inlet covers the oil smoke which flows upwards over the main turnover cover so as to enter the auxiliary air inlet to be discharged outwards. The residual oil smoke is eliminated by the oil smoke absorption and discharge twice, and an ideal smoke exhaust effect is achieved. When the range hood stops using, the inner and outer flip covers reset to close the main air inlet and the auxiliary air inlet, so that the peculiar smell of the oil stain remained in the main engine of the range hood is isolated from being emitted outwards, and meanwhile, the smooth surface of the flip cover is very easy to wipe and clean.

Description of the drawings

Fig. 1 is a schematic view of the double-air-inlet range hood with the inner and outer flip covers of the present invention.

Illustration of the drawings: 1. a main air inlet; 2. an inner flip cover; 3. an auxiliary air inlet; 4. an outer flip cover; 5. a switch; 6. an illuminating lamp; 7. a body; 8. an everting stent; 9. an inverted fulcrum; 10. an oil cup. Fifth, detailed description of the invention

The following will further explain the implementation process of the double-air-inlet range hood with the inner and outer flip covers of the present invention with reference to the accompanying drawings:

(I) the manufacturing process: the manufacturing process is the same as the manufacturing process of a common range hood, and the manufactured equipment such as a punch press, a plate shearing machine, a bending machine, a welding machine and the like does not need special configuration, and only stainless steel plates, motors and accessories are purchased to manufacture and assemble according to the design requirements of drawings.

(II) use process: when cooking, the switch of the range hood is turned on, the fulcrum shaft rotates, the inward-turning cover is turned inwards, and the main air inlet is exposed; and synchronously, the outer turnover cover is turned outwards, and the auxiliary air inlet is opened. The stove is ignited, the oil smoke rises and is guided to flow down by the inner turnover cover and is sucked into the smoke machine through the main air inlet, and a small part of the oil smoke which does not enter is upwards drifted and is covered by the outer turnover cover to be pressed into the auxiliary air inlet by atmospheric pressure and is discharged outwards. The inner flip cover of the range hood plays a role in guiding oil smoke generated during cooking, so that the suction force of the range hood is enhanced, and meanwhile, the oil smoke is absorbed and discharged twice, so that residual oil smoke is eliminated, and an ideal smoke exhaust effect is achieved. When the range hood stops using, the inner and outer flip covers reset to close the air inlet, so that the peculiar smell of the oil stain remained in the main engine of the range hood is isolated from being emitted outwards, and meanwhile, the smooth surface of the flip cover is very easy to wipe and clean.
