Problems solved by technology

[0004] Since the oil guide is installed in the air duct through which the air flow passes, it will not only generate greater resistance to the air flow and increase the noise of the air flow, but at the same time, when the range hood is working, the oil droplets dripping from the volute can easily float out of the oil guide , thereby affecting the oil-conducting effect
In addition, most of the current range hoods do not have deflectors, and the air flow directly enters the air duct system through the oil net. The range hood with this structure cannot guide the air flow into the air duct system well, resulting in a relatively small air intake.
A deflector is installed in some range hoods, and the deflector is only a flat plate structure arranged obliquely, which is respectively fixed on the front side plate of the volute and the shell of the smoke collecting chamber by screws. The structure can only play the role of guiding the airflow into the air duct, and cannot play a good oil guiding effect

Embodiment 1

[0035] Such as image 3 and Figure 4 As shown, this embodiment provides a range hood, which includes a smoke collecting chamber 1, an oil screen 2 and an air duct assembly. tuyere 10. Cooking fume directly enters the air duct assembly after passing through the smoke collecting chamber 1 and the oil screen 2, and finally is discharged from the air outlet 10 on the top of the air duct assembly. An air outlet hood 11 is installed at the air outlet 10, and a check valve 12 is installed in the air outlet hood 11 to prevent the flue gas from flowing backward in the flue.

[0036] The air duct assembly includes a volute 3, a motor 4, an impeller 5, a main box 6 and a casing 7. The casing 7 is installed on the outside of the main box 6 for protection and decoration. The impeller 5 is installed on the side of the volute 3. Inside, the motor 4 drives the impeller 5 to rotate, and the main box 6 is fixedly connected with the casing 7 and the casing of the smoke collecting chamber 1 ....

Embodiment 2

[0067] The difference from Embodiment 1 is that no inspection cover is provided, but the front end of the front plate 61 of the main box 6 is directly fixed to the case 7 by screws, and the case 7, the front plate 61 and the top plate 63 are used to form a Exhaust air duct 14. To make the structure simpler, in order to reduce noise, a layer of sound-absorbing and vibration-damping material can be pasted on the inner wall of the casing 7 . During routine maintenance, only the cover shell 7 needs to be disassembled.

Abstract

The invention relates to a flow guide structure of a kitchen ventilator as well as the kitchen ventilator. The flow guide structure of the kitchen ventilator comprises a smoke collecting cavity and anair flue assembly; the air flue assembly comprises a volute casing; a flow guide plate is arranged between the smoke collecting cavity and the volute casing; the flow guide plate is inclined downwards from front to back; a sunken part which is sunken towards a direction departing from the volute casing is arranged on the flow guide plate and corresponding to an oil dripping port; an oil leaking port is arranged on the tail part of the sunken part; the sunken part extends along a moving direction of gas flow; and a smoke inlet channel is formed below the flow guide plate to guide the gas flowto enter an air inlet side of the volute casing. The flow guide structure of the kitchen ventilator integrates the functions of guiding flow, dividing flow and guiding oil, so that the low guide structure of the kitchen ventilator can guarantee that the gas flow can enter an air flue system, facilitate increment of air inlet quantity and reduce noise caused by gas flow movement, and can effectively prevent oil drops from flowing around to achieve good oil guide effect. The flow guide structure of the kitchen ventilator integrates the functions of guiding flow, dividing flow and guiding oil, sothat the structure of the air flue system of the kitchen ventilator is simplified and material and manufacturing costs are reduced.

Description

technical field [0001] The invention belongs to the technical field of kitchen household appliances, and in particular relates to a flow guide structure of a range hood and the range hood. Background technique [0002] The range hood provides a technical means for purifying the kitchen environment and is widely used in family kitchens. Because the cooking fumes of Chinese users are generally large, the operating conditions of range hoods are relatively poor, and with the improvement of modern living standards, users have higher and higher requirements for range hoods. First of all, the performance of the range hood needs to meet the basic needs of users, that is, high wind pressure and large air volume; second, it must have a good user experience and low noise; finally, it must ensure product quality in an environment with heavy oil pollution. [0003] Such as figure 1 and figure 2 As shown, the current range hood is mainly composed of the smoke collecting chamber 1, the...
