Side-suction type range hood

Abstract

The invention discloses a side-suction type range hood. The side-suction type range hood comprises a shell body, a face plate arranged on the front side of the shell body and provided with an air inlet, a smoke baffle capable of opening or closing the air inlet, and a driving transmission component used for driving the smoke baffle to rotate, wherein the driving transmission component comprises adriving mechanism and a transmission mechanism for transmitting driving force of the driving mechanism to the smoke baffle, the transmission mechanism is connected between the face plate and the smokebaffle and is characterized in that the whole transmission mechanism is of an integrated structure and is connected with the middle position of the smoke baffle. Compared with the prior art, the range hood has the advantages that one integrated, and further symmetrical transmission mechanism is connected to the middle of the smoke baffle, so that the motion lag phenomenon and the motion imbalancetorque of the smoke baffle are eliminated, the gap difference and the step difference are kept within an allowable error range, the process of compensating the step difference and the gap differenceis eliminated, and the labor cost and the material cost are saved.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a side suction range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top-suction and side-suction types. Top-suction range hoods use the principle of rising hot air to absorb and exhaust the naturally rising oil fumes generated during cooking. It has become more and more widely used; the side suction range hood uses the vortex wind pressure to move away, and absorbs most of the oil fume close to the stove in the form of an arc, which can reduce the adverse effects on human health, and the power source Closer to the cooktop, basically will not reduce the suction effect of the power source. [0003] Existing side-suction range hoods usually have an air inlet on the panel. In order to prevent the air inlet from being exposed when the range hood is not working, which is not b...

Problems solved by technology

However, this kind of design compensation cannot usually be determined at one time, and the prototype needs to be produced and adjusted repeatedly according to the actual situation, which is a cumbersome process.

At the same time, after controlling the gap difference and step difference between the smoke baffle and the upper and lower panels through compensation, since the rotation centers of the main driving end and the driven end are not on the same straight line, an unbalanced moment will be generated at the main driving end and the driven end, making the drive The mechanism can only overcome this imbalance through the force distance generated by the deformation of the smoke baffle glass, which reduces the life of the smoke baffle driving mechanism
