Embodiment 1

[0036] This embodiment provides a range hood, such as Figure 1-Figure 2 shown, including:

[0037] The housing 1 is provided with a wind wheel 2 inside, and the housing 1 is provided with an air inlet 11;

[0038] Specifically, the casing 1 includes a volute assembly, and a wind wheel 2 is arranged at the center of the volute assembly. After the wind wheel 2 is activated, the external oil is introduced into the volute assembly, and driven by the volute assembly, Exhausted to the outside world.

[0039] In this embodiment, a fume collecting hood 8 is provided under the housing 1, such as figure 2 As shown, the oil fume inhaled through the fume collecting hood 8 will further enter the casing 1 .

[0040] A micro-nano-bubble generating device 3, the micro-nano-bubble generating device 3 communicates with the air inlet 11;

[0041] Specifically, the shape of the air inlet 11 is not limited, as long as the operation of introducing micro-nano bubbles can be realized. Such as ...

Embodiment 2

[0057] This embodiment provides a method for controlling a range hood. The range hood is provided with a water tank and a micro-nano bubble generating device, including the following steps:

[0058] Control the start-up of the micro-nano bubble generating device, and feed the micro-nano bubbles into the wind wheel;

[0059] controlling the water tank to inject water into the wind wheel;

[0060] The wind wheel is controlled to rotate at the first rotational speed.

[0061] Specifically, the order of the above steps is not limited, and the work order of different steps can be adjusted according to actual working conditions.

[0062] Through the water injection operation and the operation of introducing micro-nano bubbles, micro-nano bubble water can be formed in the volute assembly. When the wind wheel is started, the resistance of the micro-nano bubble water itself to the wind wheel is greater, and the rotation of the wind wheel can make the micro-nano bubble water The conta...

Abstract

The invention provides a range hood and a control method thereof. The range hood comprises a housing, a micro-nano bubble generating device and a water tank, wherein the housing is internally provided with a wind wheel and is provided with an air inlet; the micro-nano bubble generating device is in communication with the air inlet; and the water tank is provided with a water outlet, and water flowing out of the water outlet is suitable for entering the wind wheel. According to the range hood, the water tank is arranged, micro-nano bubble water can be formed in a volute assembly, after the wind wheel is started, the resistance generated by the micro-nano bubble water to the wind wheel is larger, meanwhile, the contact area between the micro-nano bubble water and the wind wheel can be increased through rotation of the wind wheel, and then the oil dirt removing effect can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of kitchen equipment, in particular to a range hood and a control method thereof. Background technique [0002] The range hood is a very common kitchen appliance in daily life. By turning on the range hood, the oil fumes generated during the cooking process can be sucked into the range hood first, and then further transferred to the outside atmosphere. [0003] In the range hood in the prior art, as the use time increases, various extremely stubborn oil fumes are adsorbed on components such as the volute or the wind wheel, and it is difficult to remove these oil stains by ordinary means. [0004] In order to improve the cleaning effect of the range hood itself, a range hood is provided in the prior art, which is provided with a micro-nano bubble generating device inside, and the micro-nano bubbles generated by the micro-nano bubble generating device can be released into the range hood. Inside the machine, w...
