Range hood and cooker integrated machine

Abstract

The invention discloses a rang hood and cooker integrated machine comprising a machine body, as well as a range hood and a cooker which are arranged on the machine body, wherein the range hood comprises a lampblack absorbing device, a negative pressure generation device and a lampblack exhaust device which are sequentially connected; the lampblack absorbing device comprises an air guide pipe which is arranged on the rear side of a panel of the machine body and a positive pressure generation device which forms a lampblack enveloping surface together with the negative pressure generation device; the positive pressure generation device comprises a fan and a blow pipe connected with the fan; and the blow pipe is provided with a blowing port and arranged on the panel of the machine body, corresponding to the air guide pipe, so that the lampblack enveloping surface is formed between the blowing port and an air sucking port. The invention has the advantages of small size, uniform negative pressure area, high suction rate of lampblack, favorable oil leakage preventing performance, low noise and the like; in addition, the rang hood and cooker integrated machine can be used for thoroughly sucking and exhausting he lampblack and waste gas and separating the lampblack, improves the operation efficiency of the fan and prolongs the cleaning period and the service life of the complete machine.

Description

technical field [0001] The invention relates to a kitchen oil fume suction and exhaust device, in particular to a range hood integrated machine with a positive pressure envelope surface. Background technique [0002] At present, the mainstream kitchen oil fume suction and exhaust device on the market is the range hood, and its forms mainly include top suction type, deep well ring suction type and side suction type. As we all know, the smaller the distance between the oil fume source and the suction port of the range hood, the higher the oil fume removal rate. The traditional top-suction range hood is installed above the cooker. Due to its structural limitations, the distance from the source of oil fume is usually 50-100 cm. The distance between the negative pressure area generated by it and the source of oil fume is relatively large, and it is easily affected by the ambient wind. , It is very easy to cause the diffusion of lampblack, pollute the indoor environment, and caus...

AI Technical Summary

Problems solved by technology

The traditional top-suction range hood is installed above the cooker. Due to its structural limitations, the distance from the source of oil fume is usually 50-100 cm. The distance between the negative pressure area generated by it and the source of oil fume is relatively large, and it is easily affected by the ambient wind. , it is very easy to cause the diffusion of oil fume, pollute the indoor environment, and cause human discomfort

[0003] The application number is "200710164568.7", and the Chinese invention patent application titled "Fume Range Hood Integrated Machine" discloses the deep well ring suction range hood, see figure 1 , the cooker hole 200 is located on the panel 100 of the fuselage 400, and the wall of the cooker hole 100 is provided with a suction port 300. The distance of the suction port is reduced to the minimum, and the negative pressure area is moved to the source of the oil fume. However, in the actual use process, it is found that this kind of range hood is not convenient for cooking operation, and some oil fume still escapes from its negative pressure envelope surface. , at the same time, there are problems in its safety, compatibility and gas economy

[0004] The Chinese invention patent with the patent number "ZL200720108497.4" and the patent name "side-suction range hood" discloses a side-suction range hood, which maintains an appropriate distance between the source of the lampblack and the suction port of the range hood, but The oil fume escaping from the negative pressure area cannot be removed, and the effect of exhausting the oil fume is still not very satisfactory. Long-term use will still cause pollution to the indoor environment
