Description

A multi-claw range hood

technical field

The utility model belongs to the technical field of household appliances, in particular to a range hood with multiple claws.

Background technique

With the improvement of people's living standards, range hoods have become an indispensable household appliance for restaurants, restaurants, hotels, restaurants, and families. Generally, the installation height of the top-suction range hood is about 700mm, and the fan power of its mainstream models is mostly between 200-250W, so its effective suction radius is about 400mm, so the pot surface is completely sucked by its fan. Outside the range, so that the oily smoke will naturally spread around as soon as it is generated from the pot surface. If you want to pump it cleanly, from the principle of aerodynamics, it only needs to lower the height so that the effective radius of its suction can cover the surface of the pot. Naturally, 99% of the suction effect can be achieved, but this is obviously impossible. Stir fry.

In terms of oil fume filtration, the general top suction range hood adopts the oil filter method. There are one, two or more layers, and the filter holes are square, rhombus, round, etc. The purpose is to block the oil fume through the filter, but from the use of so many years, the effect of this solution is very poor. A well-known brand promotional material frankly told: Even if the filter screen is as small as 0.01 square centimeters, 37% of the oil fume still cannot be blocked, and most of the filter screen holes in the market are about 0.04 square centimeters, so it is almost If it is directly discharged, the result is that the inner wall of the hood is polluted, causing a large amount of uneven oil accumulation on the fan impeller, and the fan rotation loses dynamic balance, so the suction effect is naturally getting worse and worse, and its mechanical noise is getting louder. In short, there is no effective purification function, so that the efficacy of traditional hoods declines rapidly.

Due to the defects in the ceiling design of general top-suction range hoods and the lack of effective purification methods, in order to ensure the short-term suction effect, their power is generally high (mainstream models are between 200W-250W), which is obviously very energy-consuming. Electricity. At the same time, due to the lack of effective purification means, a large amount of oil accumulates in the fan and the inner cavity of the machine, and cleaning is very difficult. Generally, professionals are required to complete it. Sometimes the effect is worse after cleaning, which is time-consuming and laborious.

There is an existing patent (201610515155.8 Intelligent range fume system with cleaning device) the main body of the range hood is equipped with an ultrasonic cleaning device, a filter screen and a second filter device, which realizes the function of automatic cleaning or intelligent cleaning, but all of them are aimed at the existing range hood The machine needs to be cleaned regularly, and the cleaning is difficult to design.

The existing patent (201520338636.7 a top-suction range hood) is installed on the ceiling through the mounting base, lugs and connecting rods, and the range hood body and connecting rod can swing around the mounting base by holding the handle so as to absorb the dust around the range hood body. Oil fume: Rotating the range hood body around the connecting rod can also place the air inlet of the range hood body in different directions so that the oil fume can be absorbed.

The above research does not involve the technical aspects of the TPU-wrapped stainless steel flexible multi-claw movable mechanism to realize the manual adjustment of the position of the oil suction port and the extractable main and auxiliary double filter structure. There are no relevant patents, documents and practical products of the range hood placed on the top of the gas stove that adopts a flexible movable multi-claw suction pipe, can extract the main and secondary filter structure, and can adjust the position of the range hood at will.
