Mechanical rotary component and household electrical appliance

Abstract

The invention provides a mechanical rotary component and a household electrical appliance. The mechanical rotary component comprises an internal rotary knob and an external rotary knob. A rotating shaft hole is formed in the inner end surface of the internal rotary knob; and the external rotary knob sleeves the internal rotary knob. The axes of the rotation centers of the internal rotary knob and the external rotary knob are superposed. A lock hole is formed in one of the internal rotary knob and the external rotary knob and a slide lock unit corresponding to the lock hole is arranged at the other one; the slide lock unit can be inserted into or move out of the lock hole, thereby realizing connection or disconnection of the internal rotary knob with the external rotary knob. According to the mechanical rotary component, when the appliance needs to be started, the slide lock unit is inserted into the lock hole and the internal rotary knob and the external rotary knob are connected; and the internal rotary knob and the external rotary knob can rotate coaxially, thereby realizing normal starting of the appliance. When the appliance is not in use, the slide lock unit moves out of the lock hole and the internal rotary knob with the external rotary knob are separated; and the internal rotary knob dose not rotate with the external rotary knob, so that the appliance can not be started. Therefore, a risk that the children are burned and the appliance works in a no-load state because of starting of the appliance due to misoperation by the children can be eliminated.

Description

technical field [0001] The present invention relates to the field of household appliances, more specifically, to a mechanical knob assembly and a household appliance including the mechanical knob assembly. Background technique [0002] At present, many household appliances on the market use the method of rotating the mechanical knob to control the working state of the household appliance. When the household appliance is powered on, you only need to turn the mechanical knob to start the household appliance. However, in this In this case, when children are not supervised by an adult, it is easy to turn the mechanical knob and start the household appliance, which poses a great safety hazard. For example, microwave oven is welcomed by many families as a fast-cooking microwave appliance with high quality and low price. For the use of microwave oven, the most important thing is safety issue, especially children's misuse is easy to cause harm to their bodies. Among the two existin...

Problems solved by technology

[0002] At present, many household appliances on the market use the method of rotating the mechanical knob to control the working state of the household appliance. When the household appliance is powered on, you only need to turn the mechanical knob to start the household appliance. However, in this In this case, when children are not supervised by adults, it is easy to turn the mechanical knob and start the household appliances, which poses a great safety hazard

For example, microwave ovens, as fast-cooking and inexpensive microwave appliances, are welcomed by many families. For the use of microwave ovens, the most important thing is safety issues, especially children's misuse can easily cause harm to their bodies.

Among the two existing microwave ovens, the electronic microwave oven has applied the child lock function very early. It can realize the program setting through the PCB board, thus solving the problem of misuse by children; but the mechanical microwave oven has not been very good. Solve the problem of misuse by children without supervision. Such microwave ovens have great potential safety hazards, which is one of the concerns of consumers, and it is also a problem that we need to solve urgently.

[0003] Specifically, the existing mechanical microwave ovens generally have two mechanical knobs, the upper one is the power selection knob, and the lower one is the time selection knob. As long as the time knob is turned, the microwave oven will start. In this case, when children Without adult supervision, it is easy to turn the knob and start the microwave oven, causing children to be easily scalded by the high-temperature food inside, and there is also the risk of the microwave oven working without load
