Problems solved by technology

Nevertheless, under special circumstances, it is inevitable that smoke will escape, such as when cooking heavy oil fume ingredients; or when the public flue is too congested, the oil smoke is not clean or the oil fume is not discharged smoothly; or the range hood has been used for a long time When not in use, the non-return vane at the exhaust port of the range hood is stuck by oil stains, and the wind pressure of the conventional gear cannot expand the non-return vane when the range hood is started, and the oil fume cannot be discharged; when the above situations occur, smoke will appear , pollute the kitchen indoor environment

Embodiment 1

[0041] The easy-to-clean paint consists of the following components in parts by weight: 65 parts of polytetrafluoroethylene, 15 parts of polyamideimide, 5 parts of curing agent, 3 parts of leveling agent, and 20 parts of thinner. The curing agent is a trimer type curing agent, and its function is to make the easy-clean coating to be cured under normal temperature and baking conditions. Since polyamide-imide also has a curing effect, the amount of curing agent is relatively less. The leveling agent is polyacrylic acid, which can promote the coating to form a flat, smooth and uniform coating film during the drying and film-forming process. The diluent methanol is used to adjust the viscosity when spraying.

Embodiment 2

[0043] The easy-to-clean paint consists of the following components in parts by weight: 70 parts of polytetrafluoroethylene, 20 parts of polyamideimide, 3 parts of curing agent, 4 parts of leveling agent, and 30 parts of thinner. The curing agent is a trimer type curing agent, and its function is to make the easy-clean coating to be cured under normal temperature and baking conditions. Since polyamide-imide also has a curing effect, the amount of curing agent is relatively less. The leveling agent is polyacrylic acid, which can promote the coating to form a flat, smooth and uniform coating film during the drying and film-forming process. The diluent methanol is used to adjust the viscosity when spraying.

[0044] The control method of the range hood with anti-running smoke function of the present invention, the specific process is as follows:

[0045] After starting the smoke monitoring mode, turn on the cleaning device, and the cleaning time is T. After the cleaning device ...

Abstract

The invention discloses a range hood with a smoke leakage prevention function. The range hood comprises a machine body (7); a flue system and a controller are arranged in the machine body (7); a fan is arranged in the flue system, and is electrically connected with the controller; a smoke leakage detecting device is arranged on the side wall of the machine body (7), and includes a light source sensor; a light transmitting plate (3) is arranged on the side wall of the machine body (7); a light source emitting tube (1) of the light source sensor is arranged in the machine body (7), and is positioned on the inner side of the light transmitting plate (3); the light source sensor is electrically connected with the controller; light rays generated by the light source emitting tube (1) of the light source sensor are emitted out through the light transmitting plate (3); and a layer of transparent easy-cleaning paint is arranged on the outer surface of the light transmitting plate (3). The smoke leakage prevention function of the range hood can detect escaped oil smoke; and gears can be automatically switched according to detected signals to enhance the operation air pressure and suction of the range hood so as to eliminate the smoke leakage phenomenon.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, and more specifically relates to a range hood with the function of preventing smoke from running out and a control method thereof. Background technique [0002] With the continuous improvement of people's living standards and the continuous improvement of living conditions, the range hood has become an essential household appliance in the kitchen, which has played a great role in the cleanliness of the kitchen. The range hood is installed above the kitchen stove, which can quickly take away the waste burned by the stove and the oil fume harmful to the human body produced during the cooking process, and discharge it outdoors to reduce pollution and purify the air. Nevertheless, under special circumstances, it is inevitable that smoke will escape, such as when cooking heavy oil fume ingredients; or when the public flue is too congested, the oil smoke is not clean or the oil fume is not d...
