Abstract
The utility model discloses a food processing device with a fast brake apparatus, comprising a food container with an upper cover capable of being opened. The food container is provided with a motor and a cutter head disposed on the motor. The anode and cathode of the motor are connected to an input power supply, and a brake switch is disposed between the anode and the cathode of the motor. With simple structure and fast brake speed, the food processing device is especially suitable for food processing devices like a juicer.
Description
Technical field
The utility model relates to the household appliances technical field, particularly a kind of food processing apparatus with fast braking device.
Background technology
At present, food processing apparatus (for example fruit juice mixer etc.) all is equipped with d.c. motor (motor), generally can be divided into not possessing braking function and possessing two types of braking functions, wherein:
The food processing apparatus that does not possess braking function stops operating with slower speed in product outage back, and when the user opened loam cake, if motor does not stop operating as yet, the user was hurt by the cutter tooth on the cutterhead easily.Be necessary for avoiding this type of dangerous generation, by rights it being braked.
The food processing apparatus that possesses braking function adopts the braking of mechanical type method usually, promptly utilizes the direct stuck rotation section of mechanical system to assign to reach the effect of braking.But, realize braking effect through mechanical system, cause that product structure is complicated, the life-span is short, braking time is unstable, and shortcoming such as braking effect difference.
Summary of the invention
In order to improve above-mentioned defective of the prior art, the purpose of the utility model is to provide a kind of food processing apparatus with fast braking device.
The technical scheme that the utility model adopted: a kind of food processing apparatus with fast braking device; Comprise and have the food containers that to open loam cake; Be provided with motor in the said food containers; And being installed in the cutterhead on the motor, positive and negative the two poles of the earth of said motor are connected with the input power supply, also are connected to brake switch between positive and negative the two poles of the earth of said motor.
Positive and negative the two poles of the earth of above-mentioned said motor are connected with brake switch through current-limiting resistance.
Said motor is a d.c. motor.Positive and negative the two poles of the earth of said d.c. motor are connected with AC power through rectification circuit.
The utility model is not influencing under the product prerequisite in service life, can realize fast braking effect safely and reliably, has simple in structurely, and advantage such as retro-speed is fast is specially adapted to food processing apparatus such as fruit juice mixer.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Circuit theory diagrams when Fig. 2 is the motor running of the utility model;
Fig. 3 is the circuit theory diagrams in motor when braking of the utility model.
The specific embodiment
As shown in Figure 1; The said food processing apparatus with fast braking device of the utility model comprises having the food containers 5 that can open loam cake 1, is provided with motor 6 in the said food containers 5; And be installed in the cutterhead 4 on the motor 6; Positive and negative the two poles of the earth of said motor 6 are connected with the input power supply, in addition, also 2 are connected to brake switch 3 through going between between positive and negative the two poles of the earth of said motor 6.Said motor 6 is a d.c. motor, and positive and negative the two poles of the earth of this d.c. motor are connected with the 220V AC power through rectification circuit, and its positive and negative the two poles of the earth are connected with brake switch 2 through current-limiting resistance.
The operation principle of the utility model is: food processing apparatus (for example fruit juice mixer) is in operation process; Short circuit d.c. motor when cutting off main power source; The inverse electromotive force that will produce because of inertia imports in the circuit of d.c. motor own; Produce a moment in the opposite direction thus, thereby make the d.c. motor fast braking with inertia.
As shown in Figure 2, when food processing apparatus (fruit juice mixer) when normally using, brake switch is in the position of " ON ", major loop conducting this moment, and d.c. motor (Motor) runs well.
As shown in Figure 3; When food processing apparatus (fruit juice mixer) shutdown (braking); Brake switch is in the position of " OFF ", the direct short circuit of the positive and negative electrode of d.c. motor, and this moment, motor self formed a loop; Motor induced inside electromotive force (BackEMF) produces the moment opposite with the rotor direction of rotation, makes the motor fast braking.Regulate the resistance of resistance R as required, can adjust the time of braking.
The utility model can be realized fast braking effect safely and reliably, has simple in structurely, and advantage such as retro-speed is fast is specially adapted to food processing apparatus such as fruit juice mixer.
