Embodiment 1

[0040] Embodiment one sees figure 1As shown, the device is applied in a centrifugal range hood 1, which includes a housing 10 and an impeller 2 located inside the housing, and also includes a water mist device that forms a water film layer on the inner wall of the housing and the outer surface of the impeller 2 , the water mist device is arranged on one side of the air inlet of the impeller 2; the inner wall of the housing 10 is provided with a water tank 3 that collects the circulating water of the water film layer on the inner wall; the water mist device and the water tank 3 are sequentially connected with Outlet pipe 6, water pump 4 and water suction pipe 5.

[0041] Using the water pump 4 to supply water to the water mist device can control the water intake very conveniently, so that the water mist device can continuously and stably spray water mist particles. In order to reduce the diameter of water mist particles and provide uniform distribution of water mist particles,...

Embodiment 2

[0048] Embodiment two see figure 2 As shown, the difference from the first embodiment is that the device is connected to the axial flow range hood 9, including the housing 10 and the fan blade 8 inside the housing, and also includes the inner wall of the housing and the fan blade 8 A water mist device forming a water film layer on the surface, the water mist device is arranged on one side of the air inlet of the fan blade 8; the inner wall of the housing 10 is provided with a water tank 3 for collecting circulating water of the water film layer on the inner wall; A water outlet pipe 6 , a water pump 4 and a water suction pipe 5 are sequentially connected between the water mist device and the water tank 3 .

[0049] The water tank 3 is detachably connected to the housing 10; the water tank 3 is a circular ring, and a circle is arranged along the lower inner wall of the housing 10; or the water tank 3 is a strip structure, and is arranged along one side of the inner wall of the...

Embodiment 3

[0052] Embodiment three see image 3 As shown, different from Embodiment 1, a purifier is also provided in the exhaust duct 12 of the range hood; the purifier is suitable for reducing the emission of oil fume when the amount of oil fume discharged by the centrifugal range hood is large. , and the purifier can purify oil fume, which is beneficial to protect the environment. The purifier includes a group of demister plates 13 for blocking the water-oil mixture and a collection tank 14 located below the demister plates 13; the demister plates 13 are distributed alternately, and the demister plates 13 are used for blocking the water-oil mixture, The water mist and oil fume flowing through the impeller 2 form a water mist-oil fume mixture, and the larger particles in the water mist-oil fume mixture sink due to one or more inertias with the defogging plate 13 to form a water-oil mixed liquid flow. Finally, it is collected by the collection tank 14 located under the multiple defoggi...

Abstract

The invention relates to a fan anti-sticking oil and oily dirt cleaning device, a range hood and a method of cleaning the range hood; the cleaning device comprises a spraying device disposed on one side of an air intake of a rotary wheel and a water trough arranged below the inner wall of a fan housing; an outflow pipe, a water pump and a water suction pipe are connected sequentially between the spraying device and the water trough. The range hood comprises a housing and a the rotary wheel disposed in the housing and also comprises a spraying device that forms a water film layer formed on the inner wall of the housing and the outer surface of the rotary wheel. In use, it is difficult for fume to stick to the surface of the rotary wheel, a flue and the housing, the inside and outside of the range hood are very clean, there is no need to clean or replace an impeller or blades in long-term operation, and the greatest problem of traditional fume extracting equipment is thoroughly solved; very little water is used; the technique is simple and practical and is very low in cost; it is difficult for oil to accumulate on the surface of parts, and a fire hazard is thoroughly avoided; the same device may be used, and spray containing an emulsifying agent may be used to clean residual oily dirty on the rotary wheel and inner wall of the range hood after use for a period of time.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood cleaning device and a cleaning method thereof. Background technique [0002] Existing various low-grade range hoods cannot solve the problem of fan sticking oil. While the high-speed rotation produces strong suction, the impeller of the centrifugal fan is the part that is most likely to adhere to the oil fume, followed by the inner wall of the casing facing the direction of rotation of the impeller. The actual measurement shows that when a brand-new impeller sprayed with Teflon and other non-stick coatings is put into operation, it only needs to fry 1 or 2 dishes, and each blade will be covered with a layer of oil. After 10 days and a half months, the oil stains on the blades are already considerable. After 1 to 2 months, due to the uneven accumulation of oil dirt, it will lead to the unbalanced rotation of the fan, which not only increases the noise, but also reduces th...
