Smoke leakage prevention side suction type range hood convenient to maintain

Abstract

The invention relates to a smoke leakage prevention side suction type range hood convenient to maintain. The range hood comprises a shell and a front panel. The top face of the shell is perpendicular to the back face of the shell. The front panel is provided with an air suction opening. An upper smoke baffle and a lower smoke baffle which are capable of rising and falling are installed on the front face of the front panel. Two independent drive mechanisms driving the upper smoke baffle and the lower smoke baffle correspondingly are arranged in the shell. An oil collection cup is arranged at the bottom of the lower smoke baffle. After the lower smoke baffle moves downwards, the plane where the lower smoke baffle is located intersects the plane where the back face of the shell is located. The drive mechanisms comprise asynchronous motors installed on the back face of the front panel. Output shafts of the asynchronous motors drive driving gears to rotate. The driving gears mesh with driven gears. The outer diameters of the driving gears and the outer diameters of the driven gears are the same. The back faces of the upper smoke baffle and the lower smoke baffle are each provided with a concave part. The left side walls and the right side walls of the concave parts are each provided with a rack. The driving gears and the driven gears mesh with the racks on the left side walls and the right side walls of the concave parts correspondingly. The side suction type range hood provided by the invention has the characteristics of being convenient to maintain, free of smoke leakage and good in oil smoke suction effect.

Description

technical field [0001] The invention relates to a range hood, in particular to a side-suction type range hood which is smoke-proof and easy to maintain. Background technique [0002] Because the air inlet of the side suction range hood is closer to the source of the oil fume, it can lock the oil fume in the first place, and can effectively shorten the moving distance of the oil fume rising, so the smoke exhaust effect is naturally more ideal. Because it adopts an open design on the appearance of the smoke collection chamber, which increases the range of cooking space, there is no sense of depression when cooking, and it can effectively avoid the occurrence of meeting incidents, so it is more and more favored by consumers. [0003] The side-suction range hood is mainly installed against the wall when in use, and there is a large space between the bottom of the front panel of the range hood and the wall. Therefore, the large oil collecting cup can easily block the oil fume, a...

Problems solved by technology

[0003] The side-suction range hood is mainly installed against the wall when in use, and there is a large space between the bottom of the front panel of the range hood and the wall. The bottom of the range hood is on the bottom of the range hood, so the wide oil collection cup can easily block the lampblack, and it is easy to cause the lampblack to escape from the oil collection cup to the back of the range hood, which seriously affects the smoke exhaust effect of the side suction range hood

Moreover, the current design structure of the side-suction range hood is not very convenient for maintenance. When the fan fails, the range hood needs to be disassembled completely, and the fan can only be taken out by opening the shell, which is very inconvenient.
