a cooking device

Abstract

The invention belongs to the technical field of electrical equipment and relates to a cooking device. The main structure of the cooking device comprises a power plug, a power switch, a power indicator lamp, a heating plate, a first time relay, a second time relay, a buzzer, a liquid level sensor and the like. In the using process, the cooking device is powered on, and the heating plate starts heating; when the liquid level in the cooking device is lower than the position of the liquid level sensor, the buzzer starts alarming, and the first time relay starts timing; if nobody conducts operation when set time is up, a delay opening contact of the first time relay is automatically switched off, meanwhile, a delay closing contact of the first time relay is switched on, and the second time relay starts timing; if still nobody conducts operation when set time is up, a delay opening contact of the second time relay is automatically switched off, and the device enables a whole circuit to be switched off. The cooking device is simple in main structure, safe and reliable in principle, flexible in use, high in control automation degree and environmentally friendly, saves energy and reduces consumption.

Description

Technical field: [0001] The invention belongs to the technical field of electrical equipment, and relates to food processing equipment, in particular to a cooking device. Background technique: [0002] With the advancement of technology, the use of equipment is becoming more and more intelligent. Equipment with simple structure and single function will be gradually replaced by highly intelligent equipment. At present, under the existing technical conditions, the cooking device used in the food processing industry and daily life has a simple structure and a single function. , which is extremely dangerous to the surrounding environment and damages the cooking device. For example, the stainless steel pot used to heat rice at home is widely used in the family. This kind of pot heats up quickly when used, and consumes water in the pot quickly. There will be a phenomenon of burning the pot or even burning the pot; or a cooking device with automatic power off. After the water is ...

Equipment with simple structure and single function will be gradually replaced by highly intelligent equipment

At present, under the existing technical conditions, the cooking device used in the food processing industry and daily life has a simple structure and a single function. , which is extremely dangerous to the surrounding environment and damages the cooking device. For example, the stainless steel pot used to heat rice at home is widely used in the family. This kind of pot heats up quickly when used, and consumes water in the pot quickly. There will be a phenomenon of burning the pot or even burning the pot; or a cooking device with automatic power off. After the water is boiled dry, the user does not know, and waits for a long time before discovering that the power has been cut off and needs to be restarted. Opening the cooking device wastes a lot of time for the user, and also shortens the service life of the cooking device. For example, the heating lunch box disclosed in Chinese patent 2012104088737 is widely used in many people who go to work and travel, although the heating lunch box can be set to a regular time. , but the function is single, and it cannot ensure that the user can not only ensure that the food is heated thoroughly but also ensure safety when using it; The way of relying on steam alarm is non-intelligent, and it will bring danger to people around the cooking device
