Background

At present, electric cookers in the market mainly have two categories. One is mechanical electric rice cooker, and the other is computer electric rice cooker. At present, mechanical electric cookers in the market are generally controlled by magnetic steel temperature, namely, the magnet is connected with a connecting rod, and the connecting rod is controlled by a complex hardware component, a copper sheet and a contact. The mechanical electric cooker cannot automatically control food such as soup, porridge and the like, and is easy to overflow, dry and scorch. Although foods such as porridge and soup can be automatically controlled in the computer cooker in the market, electronic elements such as chips and sensors are used, and are easily affected by water vapor and water flowing into a circuit board, so that the computer cooker is unstable in performance, short in service life and high in failure rate. In addition, the circuit board also has influence on the altitude, so that the work failure is easily caused, and the computer chip is in short supply and expensive and has high cost.

Detailed Description

The utility model will be further described in detail with reference to the following embodiments, as shown in fig. 1, a multifunctional automatic electric cooker comprises a cooker body, a cooker cover, an inner container and a three-jack or Y interface which is arranged on the cooker body and is provided with a grounding end, wherein one wiring end of the interface is sequentially connected with a thermal fuse RU, a timer T, a central temperature control switch K1, a temperature control switch K2 and a heating plate RL in series, and finally connected with the other wiring end of the interface, and the thermal fuse RU is sequentially connected with a thermal insulator W and the heating plate RL in series; the timer T comprises three gears, namely a normally open gear, a neutral gear and a timing gear; the central temperature control switch K1 and the temperature control switch K2 are bimetallic strip temperature control switches; the central temperature control switch K1 is arranged on the heating plate RL; two ends of the temperature control switch K2 are connected in parallel with a diode D, and the temperature control switch K2 is arranged at the bottom of the cooker body or on the cooker cover; the heat retainer W is a heat retaining sheet or bimetallic strip temperature controller; the heating plate RL, the heat retainer W and the temperature control switch K2 are all connected in parallel with an indicator light assembly; the indicating lamp assembly and the diode D are arranged on a circuit board; the indicating lamp assembly comprises a protective resistor and an indicating lamp which are connected in series. The central temperature control switch K1 is a KSD301/302 series of the converging dragon electric appliance; the temperature control switch K2 is KSD301/302 series of converging dragon electric appliances arranged at the bottom of the cooker body or KSD9700 series of Longde electric appliances arranged on the cooker cover.

The multifunctional automatic electric cooker of the embodiment has two working modes, wherein one is a cooking mode for cooking soup, porridge, rice, vegetables and the like, and the other is a cooking mode. The working principle of the two modes is as follows:

steaming and boiling mode

Food is put in, the timer T is shifted to a timing gear from a neutral position, the time required for steaming the food is adjusted, and the heating plate RL starts to heat. When the water in the pot is nearly boiled, the temperature of the inner layer with the heating plate RL rises, the temperature control switch K2 arranged at the bottom of the pot body is continuously heated to reach the set temperature, and the contact is disconnected, according to the same principle, if the temperature control switch K2 is arranged on an aluminum sheet on the inner layer of the pot cover, the temperature of the steam in the pot body rises, and when the temperature controller K2 reaches the set temperature, the contact of the temperature control switch K2 jumps, so that the current passes through the diode D, the heating plate RL enters a low-firepower state, and the water and the food in the pot cannot overflow. The operation is carried out until the food is cooked, and when the timer T returns to the neutral position, the cooking is finished and the heat preservation state is entered.

② cooking mode

When cooking is needed, the timer T is adjusted to a normal open gear from a neutral position, namely a cooking gear, the cooking work is started, the heating plate RL starts to heat to enable water in the pot to reach a boiling state, the temperature control switch K2 is switched off along with the rise of the internal temperature, the current passes through the heating plate RL from the diode D to achieve the effect of automatic fire reducing, and the central temperature control switch K1 is switched off to enter a constant heat preservation state when the water is dried and cooked rice reaches a set temperature, so that the cooking is finished. When the rice cooking is not needed for a long time, the timer T is adjusted to be neutral.

The above description is only for the purpose of illustrating the technical solutions of the present invention, and those skilled in the art can make simple modifications or equivalent substitutions on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
