Description

Knob lock safety device for rice cooker

technical field

The utility model relates to the field of electric cookers, in particular to a safety device for locking buttons of the electric cooker.

Background technique

An electric rice cooker is a modern cooker capable of steaming, boiling, stewing, simmering, and braising. It can not only cook food, but also keep it warm. It is clean and hygienic to use, without pollution, saving time and effort. It is one of the indispensable tools for the modernization of housework. The invention of the electric rice cooker has greatly reduced the time and manpower that ordinary families spend on cooking.

The electric rice cooker comprises a pot body and a pot cover, and the pot body and the pot cover are connected through a rotating shaft. In the working state, the lid of the pot is locked on the body of the pot to ensure that the water vapor does not overflow and increase the pressure inside the inner pot, so that the rice and cooking are completed under the action of pressure. Under the action of pressure, the rice can make the water fully penetrate into the inside of the rice grains, so that the rice grains are completely cooked. The cooked rice is more nutritious and delicious.

The existing electric cooker is generally provided with a button, and the user presses the button to release the lock between the pot cover and the pot body, thereby opening the pot cover. When the rice cooker is in the cooking state, the user opens the lid by mistake, and the hot steam in the rice cooker overflows, which not only affects the cooking of rice and dishes, but also the overheated steam may scald the user. The use safety of the rice cooker cannot be guaranteed.

Contents of the invention

The technical problem to be solved by the utility model is to provide a safety device for locking the button of the rice cooker, which can lock the button in the working state through a simple structure, so that the lid cannot be opened, so as to ensure the safety of the rice cooker.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: the lock button safety device of the electric rice cooker includes a rotary lock piece, a solenoid valve and a button arranged on the surface of the pot cover, and the described rotary lock piece is erected in the pot cover and the bottom Stretch out the pot cover and then bend and lock the pot body. The button is movably installed and connected to the upper end of the rotating locking piece. A retaining plate is horizontally arranged on the rotating locking plate, and the solenoid valve is connected with a push rod assembly, and the solenoid valve acts on one end of the push rod assembly to drive the other end of the push rod assembly to snap under the retaining plate.

A further preferred solution of the utility model: the left and right ends of the rotating locking piece are bent and used to install the rotating shaft.

A further preferred solution of the utility model: a spring assembly is connected between the upper end of the rotating locking piece and the bottom surface of the pot cover, and the spring assembly is in a compressed state.

A further preferred solution of the utility model: the middle part of the upper end of the rotating locking piece extends upwards to an extension, the button acts on the extension, pressing the button will press the extension inward to drive the rotating locking piece to rotate around the axis.

A further preferred solution of the utility model: the push rod assembly includes an arc-shaped push rod member and a cooperatingly installed limiting member, and the push rod member is movably installed in the pot cover through a shaft arranged in the middle , the shaft is arranged vertically, and the push rod can rotate around the shaft on a horizontal plane.

A further preferred solution of the present utility model: the limiter is fixedly installed above the push rod, and there is a distance between the limiter and the push rod.

A further preferred solution of the utility model: the solenoid valve is fixedly connected to one end of the push rod, and the solenoid valve will drive the push rod to rotate around the shaft.

Compared with the prior art, the utility model has the advantages that firstly, the utility model locks the pot cover and the pot body by rotating the locking piece, and the bottom of the rotating locking piece stretches out from the pot cover and bends to lock the pot body. To open the pot cover, the button is pressed down to drive the rotating locking piece to rotate around the axis, thereby withdrawing the bottom of the rotating locking piece from the pot body. Therefore, a blocking plate is horizontally arranged on the rotating locking plate, and an electromagnetic valve is arranged, and a push rod assembly is connected to the electromagnetic valve. When the electric rice cooker is in the working state, the electromagnetic valve works and acts on one end of the push rod assembly to drive the other end of the push rod assembly to snap into the bottom of the gear plate. At this time, the button is pressed down again, and because of the setting of the push rod assembly, the rotating lock piece cannot be rotated and continues to lock the pot body. The pot cover cannot be opened to ensure the safety of the rice cooker.
