Compared with the prior art, the food processor disclosed by the utility model has a better anti-spilling effect.

Description

A kind of food processor

Technical field

The utility model relates to food processing machinery, especially relates to a kind of food processor.

Background technology

Existing food processor (for example soy bean milk making machine); The anti-overflow probe all is set to prevent the slurry that overflows between the container rim of a cup and the water level upper limit; The principle of this anti-overflow probe is: when the slurries boiling; Liquid level rises on the water level upper limit and contacts with the anti-overflow probe, and make anti-overflow probe and the conductor dbus that is arranged on another place of container cross the slurries conducting and form the loop, thus the heating of control heater stop.But because food processor can produce foam in whipping process; These foams possibly just contact with the anti-overflow probe before liquid level contacts with the anti-overflow probe; Contact with the anti-overflow probe above perhaps after the slurries liquid level falls after rise to the anti-overflow probe, still being trapped in container cup, therefore can cause misoperation and make heating stop.

In addition; Also there is technological deficiency in existing food processor to the judgement of boiling point; Existing video cooking machine generally only adopts a thermometer to carry out the boiling point judgement, but owing to boiling point can change along with change of elevation, therefore for avoiding the boiling point misjudgment; Need the height above sea level of land used is provided with to the boiling point value according to product, this have rolled up the production and the management cost of product.

Summary of the invention

The utility model technical problem to be solved is, to above-mentioned defective, a kind of food processor is provided, and realizes the accurate control to heater.

A kind of food processor; Comprise container cup, heater and boiling point judgement and anti-overflow device; Said boiling point is judged and anti-overflow device comprises first temperature sensor, second temperature sensor and processor; Said first temperature sensor is arranged between the water level upper limit position of rim of a cup and container cup of said container cup, and said second temperature sensor is arranged between the water level upper limit position of the cup end and container cup of said container cup;

Said first temperature sensor all is connected with said processor with second sensor, sends the temperature detected value to said processor; Said processor also is connected with said heater, and the difference of the temperature value that is used for transmitting at said first temperature sensor and second sensor is controlled said heater stop work during less than predetermined threshold or reduced power or limit the heating duration.

Preferably, said first temperature sensor and second temperature sensor are thermistor.

Said food processor can be soy bean milk making machine, bean curd machine or other agitating heating machines.

Compared with prior art, two temperature sensors carried out anti-overflow control and boiling point judgement about the utility model adopted, and can avoid the mistake control that causes because of foam; And anti-overflow is judged and boiling point is judged the influence of having broken away from height above sea level, and the product effect not height change because of territory of use's height above sea level is different, and production and management cost are low.

The specific embodiment

Contrast accompanying drawing and combination preferred embodiment are described further the utility model below.

The food processor of present embodiment is a kind of soy bean milk making machine, and this soy bean milk making machine is judged by container cup 100, beating apparatus, heater and boiling point and anti-overflow device is formed.

As shown in Figure 1; Said boiling point is judged and anti-overflow device comprises that first temperature sensor 201, second temperature sensor 202 and processor form; Wherein, First temperature sensor 201 is arranged between the water level upper limit position that rim of a cup and the container cup 100 of container cup 100 set, and between the cup end that second temperature sensor 202 is arranged on container cup and the water level upper limit position of container cup setting, both all are fixed on the sidewall of container cup; The water level upper limit described herein is to refer to the water level upper limit graduation mark that marks on the container cup; Even but do not have under the situation of graduation mark at container cup, this water level upper limit also is an objective reality, it is that the general knowledge such as stirring state, heating state of capacity, cooking machine according to container can be known; When slurrying prepared, second temperature sensor 202 was immersed in the slurries, and first temperature sensor 201 is positioned on the slurries liquid level.

As shown in Figure 2; First temperature sensor 201, second temperature sensor 202 all are connected with processor; Be used for the detecting temperature value and send it to processor; Processor also is connected with heater, and the difference that is used for the temperature value that said first temperature sensor 201 and second sensor 202 transmit is controlled said heater stop work during less than predetermined threshold or reduced power or limit the heating duration, and how concrete selection controls heater can be selected according to actual needs.。

First temperature sensor 201 of present embodiment and second temperature sensor 202 can adopt conventional thermometer, but preferably adopt the higher thermistor element of sensitivity (NTC).

The boiling point judgement of present embodiment and the operation principle and the process of anti-overflow device are following: during beginning slurrying; First temperature sensor 201 is positioned on the liquid level, after the heating, owing to do not reach boiling point; According to heat-conduction principle; The slurries bottom temp can be higher than head temperature, therefore, even there is part to contact with first temperature sensor because of heating or stirring the foam or the slurries that produce; Its surface temperature still temperature than second temperature sensor is low, and can judge that according to the temperature difference of two temperature sensors slurries had not both reached the boiling point slurry that yet can not overflow this moment; And after the slurries boiling; Slurries roll, and liquid level rises and makes temperature sensor 202 also be immersed in the slurries fully, and temperature also will reach unanimity about the slurries; This moment, the surface temperature of two temperature sensors was identical or very approaching; The difference of temperature value is less than predetermined threshold, and processor can be judged slurries and seethed with excitement and the slurry that overflows possibly occur in view of the above, and processor sends control signal control heater stop heating or reduces power or limit the heating duration.

Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the utility model person of ordinary skill in the field; Under the prerequisite that does not break away from the utility model design; Can also make some being equal to substitutes or obvious modification, and performance or purposes are identical, all should be regarded as belonging to the protection domain of the utility model.
