Abstract

The utility model discloses an automatic power-off protection device used in opening the cover of a multifunctional household food processor. A magnet is installed on an upper cover of the multifunctional household food processor, and a magnetic inductor is mounted on the base of the multifunctional household food processor in the position corresponding to the magnet. A signal output terminal of the magnetic inductor is connected with a signal input terminal of a magnetic signal switch; and the magnetic signal switch is connected in series to power input terminals of a stirring motor and a charging motor. In the use of the multifunctional household food processor, when the upper cover is in a close state, the magnetic signal switch is in a close state as well to allow the stirring motor and the charging motor to work; and conversely, when the upper cover is in an open state, the magnetic inductor outputs signals to enable the magnetic signal switch to be in an open state, the power of the stirring motor and the charging motor is cut off, therefore, the safety accidents caused by fact that the motor operates when the upper cover is in an open state are avoided.

Description

The automatic power-off protection device of uncapping of multifunctional household food processor

Technical field

The utility model relates to a kind of automatic power-off protection device of multifunctional household food processor, relates in particular to a kind of automatic power-off protection device of uncapping of multifunctional household food processor.

Background technology

In Eurafrican a lot of countries, people like eating paste food (as cornmeal mush, sesame cream, walnut dew etc.), because they eat the frequency of paste food very high (one day two meal or more of possibility), so its cooking process is also more exquisite, general adopt multifunctional household food processor to boil rather than convert and the time of reinforced (being various powdered foods) is also had relatively high expectations with boiling water, generally reinforced when water temperature reaches 80 ℃, the food taste and the nutritive value that cook are all best.Multifunctional household food processor has temperature display function and agitating function, can cook various paste foods by user's request easily.

With traditional multifunctional household food processor cooking food, there is certain potential safety hazard: on the one hand, owing in cooking process, need ceaselessly to stir, so high temperature food can spatter in the pot civil strike, if open loam cake because of carelessness, the scald accident then takes place probably; On the other hand, if reinforced runner also causes security incident probably also in rotation when opening loam cake.In a word, if also be in running status opening the loam cake rear motor, just cause security incident probably.

Summary of the invention

The purpose of this utility model just is to provide in order to address the above problem a kind of automatic power-off protection device of uncapping of multifunctional household food processor; this device can make motor out of service after loam cake is opened automatically, thereby avoids moving the security incident that causes because of motor.

To achieve these goals, the utility model has adopted following technical scheme:

In the utility model, on described multifunctional household food processor, cover magnet is installed, on the base of described multifunctional household food processor, magnetic inductor is installed with the corresponding position of described magnet, the signal output part of described magnetic inductor is connected with the signal input part of a magnetic signal derailing switch, and described magnetic signal derailing switch is connected in series in the power input of stirring motor and reinforced motor.

In the process of using multifunctional household food processor, when loam cake was in closure state, the magnetic signal derailing switch also was in closure state, allowed stirring motor and reinforced motor in running order; Otherwise when loam cake was in opening, the magnetic inductor output signal made the magnetic signal derailing switch be in off-state, cut off the power supply of stirring motor and reinforced motor, the security incident that machine operation causes when having avoided because of the unlatching loam cake.

As optimum structure of the present utility model, described magnet is installed in an end that covers away from the loam cake rotating shaft.The benefit of this structure is: even loam cake is opened a very little angle, magnetic inductor can both be sensed the information that loam cake is opened exactly, thereby guarantees to disconnect motor power, avoids the generation of security incident.Otherwise, cover from the very near position of loam cake rotating shaft if magnet is installed in, then the problem that may cause the magnetic inductor induction sensitivity to descend because the magnet moving range is too little.

Described magnet is installed in the interlayer of loam cake, and described magnetic inductor is installed on the lower wall of top panel of base.So not only practical, and attractive in appearance.

The beneficial effects of the utility model are:

The utility model can judge exactly whether the loam cake of multifunctional household food processor is in opening, and disconnects the power supply of stirring motor and reinforced motor when loam cake is opened in time, guarantees can not occur to open the security incident that causes because of loam cake.

Description of drawings

Fig. 1 is the perspective view that comprises multifunctional household food processor of the present utility model;

Fig. 2 is one of the structure for amplifying schematic diagram of A among Fig. 1;

Fig. 3 be A among Fig. 1 the structure for amplifying schematic diagram two.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further concrete description:

As shown in Figure 1, comprise that multifunctional household food processor of the present utility model is made of the outer courage in housing 1, the housing 1, inner bag, rabbling mechanism (not visible among the figure) and charging hopper 5, wherein, housing 1 comprises loam cake 2 and base 3, charging hopper 5 places on the loam cake 2 by bell mouth 6, be provided with control panel 4 in the front of base 3, be used for realizing operations such as startup, timing.

As shown in Figure 2, on the loam cake 2 of multifunctional household food processor, magnet 7 is installed, as shown in Figure 3, on the base 3 of multifunctional household food processor, magnetic inductor 8 is installed with magnet 7 corresponding positions, the signal output part of magnetic inductor 8 is connected with the signal input part of a magnetic signal derailing switch, and described magnetic signal derailing switch is connected in series in the power input (not visible among the figure) of stirring motor and reinforced motor.

As shown in figures 1 and 3, magnet 7 is installed on the loam cake 2 in the interlayer away from an end of loam cake 2 rotating shafts, magnetic inductor 8 is installed on the lower wall of top panel of base 3 (being represented by dotted lines among the figure), the benefit of this structure is: even loam cake 2 is opened a very little angle, magnetic inductor 8 can both be sensed the information that loam cake 2 is opened exactly, thereby guarantee to disconnect motor power, avoid the generation of security incident.Otherwise,, then may cause the problem of magnetic inductor 8 induction sensitivity decline because magnet 7 movings range are too little if magnet 7 is installed on the loam cake 2 from the very near position of rotating shaft.

As shown in figures 1 and 3, in the process of using multifunctional household food processor, when loam cake 2 was in closure state, the magnetic signal derailing switch also was in closure state, allowed stirring motor and reinforced motor in running order; Otherwise when loam cake 2 was in opening, magnetic inductor 8 output signals made the magnetic signal derailing switch be in off-state, cut off the power supply of stirring motor and reinforced motor, the security incident that machine operation causes when having avoided because of unlatching loam cake 2.
