Near suction type range hood

Abstract

A near suction type range hood comprises a body, a smoke collecting hood and a blower fan; a panel and an oil filtering screen are installed on the smoke collecting hood, and the near suction type range hood is characterized in that a first temperature sensor senses the temperature an air inlet zone at the left side of the oil filtering screen; a second temperature sensor senses the temperature of an air inlet zone at the right side of the oil filtering screen; a first flow bypassing plate and a second flow bypassing plate are both installed at the back side of the oil filtering screen; a driving mechanism is installed at the back side of the oil filtering plate, drives the first flow bypassing plate and / or the second flow bypassing plate to make transverse left-right movement according to the sensed temperatures, and enables the air inlet area of two sides of the oil filtering screen to be matched with the temperature of the same-side air inlet zone. The near suction type range hood has the advantages that the near suction type range hood determines the heating status of two sides by utilizing the temperature sensors to sense the temperature filed distribution at the left and right sides of the oil filtering screen, and then determines the possibly-appeared large smoke and small smoke directions in advance, the near suction type range hood employs the driving mechanism to drive the first flow bypassing plate and the second flow bypassing plate to make transverse left-right movement for adjusting the left and right air inlet area and further for adjusting the left and right negative-pressure zone distribution, thereby improving the oil and smoke suction effect.

Description

Technical field [0001] The invention relates to a range hood, in particular to a near suction type range hood. Background technique [0002] At present, European-style range hoods on the market are divided into top-suction range hoods and near-suction range hoods. In order to fully absorb the range hoods, the near-aspiration range hoods usually pull down the fume collection hood, which is closer to the area where the fume is generated. At the same time, in order to have a better effect of absorbing oil fume, a fume-containing cavity is usually arranged at the rear of the fume collecting hood, and finally the oil fume is discharged to the outside through the suction and exhaust mechanism. [0003] The panels of the near suction range hood all include the oil filter screen. At present, the oil fume directly enters the smoke chamber without passing through the oil filter hole of the oil filter screen, and the inlet on both sides of the oil filter screen The size of the tuyere cannot ...

Problems solved by technology

Considering that most households use binocular stoves, when two pots are used at the same time, such as cooking on one side and cooking rice on the other side, the cooking side will generate more oily fumes, and the cooking side will hardly produce oily fumes. Some near-suction range hoods cannot adjust the left and right negative pressure distribution by adjusting the size of the air inlets on both sides of the oil filter screen, so there will be a phenomenon that the cooking side cannot suck in the oil fume and the negative pressure on the cooking side is wasted.

In the same principle, when only one pot is used, there will be a waste of negative pressure on the side of the unused pot
