Technical Field

The utility model relates to a lampblack purifying device, in particular to a range hood.

Background

The range hood has become one of the indispensable kitchen appliances in modern families. The general range hood comprises a top suction type range hood and a side suction type range hood, and the side suction type range hood absorbs most of oil smoke which is closer to a cooking bench in an arc line mode by utilizing the vortex wind pressure principle, so that adverse effects on human health can be reduced, and a power source is closer to the cooking bench, so that the suction effect of the power source is basically not reduced.

In order to achieve a better smoke gathering effect, a smoke baffle is usually arranged at an air inlet of the side-suction type range hood. The conventional range hood with a reversible smoke baffle is generally arranged at the rear side of the smoke baffle, and a lighting device is generally arranged at the rear side of the smoke baffle, such as the range hood disclosed in China patent with the application number of 201620475620.5. When the lighting function is needed, the range hood needs to be opened, so that the range hood is inconvenient.

The lighting device is arranged at the upper part of the outer side of the smoke baffle plate, so that the lighting can be turned on under the working condition that the smoke baffle plate is not turned on. The range hood disclosed in the chinese patent application No. 202110661318.4 comprises a main unit, a smoke collecting cavity and a smoke baffle plate assembly, wherein the smoke baffle plate assembly is mounted on the smoke collecting cavity, the main unit comprises a main unit case shell and a smoke ventilator, the smoke collecting cavity is mounted at the lower part of the main unit case shell, and the main unit further comprises an illuminating lamp. However, due to structural limitations, the illumination lamp is arranged at a higher position, and due to illumination projection after the smoke baffle is opened, the whole cooker is difficult to be completely illuminated.

In addition, both of the above forms affect the user's cooking and cleaning experience to some extent.

At this time, the smoke baffle 12 is located at the front side of the closed position, the smoke baffle 12 and the baffle 13 together form a smoke collecting cavity Q with the front surface of the back plate 111, the concave portion 114 is also formed as a part of the smoke collecting cavity Q, the smoke collecting cavity Q is communicated with the interior of the upper case 2 through the air inlet 21, and the smoke enters the upper case 2 from the rear side of the smoke baffle 12 and the baffle 13 through the air inlet 21.

In this state, the protective cover 42 partially moves to the lower part of the illuminating lamp 41, thereby realizing the illumination requirement in the working state; and because the illumination is illuminated at the rear side of the smoke baffle 12, the cookware can be basically ensured to be covered by light, and meanwhile, the internal illumination scheme solves the illumination requirement when a user cleans the inner side of the range hood. Furthermore, the protection cover 42 shields the lower part and the rear side of the illumination lamp 41, so that the lampblack is prevented from directly contacting the surface of the illumination lamp 41 when the range hood works, the oil-free working environment of the illumination lamp 41 is realized to a certain extent, and the use reliability of the illumination lamp 41 is improved. The protective cover 42 may be made of transparent and light-permeable material only at the portion below the illumination lamp 41 at this time.

The utility model realizes the extremely light and thin structure in the shutdown state, a larger air inlet channel and a larger smoke gathering range in the working state by folding and unfolding the baffle 13 at the air inlet of the range hood relative to the smoke baffle 12, and achieves the light and thin structure and the smoke absorbing effect. The form also makes the air inlet assembly 1 not need to form an air inlet channel, and the smoke baffle 12 can be close to the back plate 111 when the air inlet assembly 1 is closed, so that the whole thickness of the air inlet assembly 1 is extremely thin and light, and is preferably about ten millimeters.
