Anti-overflow food processor

Abstract

The invention discloses an anti-overflow food processor; a sensing probe is disposed at the outer surface of a cup cover close to an exhaust port, slurry never contacts the sensing probe at the outer surface during normal stirring of the processor, the slurry can contact the sensing probe at the outer surface only when overflowing through the exhaust port, a control unit is then triggered to output a stop signal to prevent overflow, and stopping of the processing, affected material crushing effect and reduced working efficiency of the processor due to misjudgment under non-overflow condition are avoided; in addition, the anti-overflow requirements in stirring crushing stage and heating stage are met, whole-course overflow prevention is truly achieved, the volume of a stirring cup may be effectively utilized, virtual increase in the volume of the stirring cup due to the failure of effective utilization of an anti-overflow rod and space below the same in the prior art is avoided, product cost is reduced, and the anti-overflow food processor is safer and more sanitary, more reliable to use, and is widely applicable to various types of food processors.

Description

technical field [0001] The invention relates to a cooking machine, in particular to a spill-proof cooking machine. Background technique [0002] A cooking machine with a heating function usually stirs and breaks the ingredients first, and then automatically heats the slurry of the ingredients, so that it can be drunk directly. But when heating to boiling, because the mixing cup that cooking machine is made up of cup body and bowl cover is close to sealing state, internal pressure increases, and the slurry in the working chamber overflows easily along the exhaust port on the bowl cover. [0003] Aiming at this phenomenon, the current solution is to fix the sensing element in the lid, and the sensing probe of the sensing element extends into the mixing cup to form an anti-overflow rod. When heating, when the tumbling boiling slurry touches the anti-overflow rod, the induction The element triggers the control unit to issue an instruction to stop working, thereby achieving the ...

Problems solved by technology

[0004] Although this structural design solves the problem of slurry overflow during the heating process, it also reduces the working efficiency of the cooking machine. This is because: during the stirring and crushing process of the materials in the mixing cup, the slurry will continuously roll and splash, which is easy to touch Touching the anti-overflow rod protruding into the mixing cup may cause the machine to stop at any time, which will eventually affect the crushing effect of the material and reduce work efficiency; Single-stage working mode, that is, the sensing element is not activated during the stirring and crushing phase, and the sensing element is activated during the heating phase

But then there will be a new problem, that is: when the amount of water added to the cooking machine is slightly high or the angle of the cooking machine is tilted, etc., or when mixing beans and other materials that are prone to generate a lot of foam or expand, During the stirring and crushing stage, the slurry in the working chamber is easy to roll and overflow. At this time, because the sensing element is not activated, the overflow judgment cannot be made in time to trigger the shutdown, which will cause the slurry to overflow continuously, not only dirty the cooking machine and the work surface, but also difficult to clean. , may also cause serious security problems

[0005] On the other hand, the anti-spill rod extends into the mixing cup. In order to avoid the tumbling slurry from touching without overflowing, the space where the anti-spill rod is located and the space of the mixing cup adjacent to it cannot be used as a working space, resulting in the The height becomes larger, but the effective volume becomes smaller, which not only causes waste, but also easily misleads the operator, making the amount of water added exceed the standard water level, resulting in subsequent problems
