Description

A cooking machine for making bread

Technical Field

The invention relates to the field of cooking appliances for kitchens, in particular to a food processor for making bread.

Background

A food processor for making bread generally has both a stirring function and a heating function, which mainly include: a body having a rotation driving function; a cup body mounted on the body; and a stirring device which is arranged in the cup body and is driven by the machine body to rotate. The food processor may also have a heating device disposed about the cup body to heat and toast the dough within the cup body to make the bread.

For the food processor with heating function, heating device usually is with cup direct contact, is provided with temperature sensor on the cup for to feeding back the temperature of cup to the food processor to the temperature of the food of cooking in the cup is controlled. Commonly used Temperature sensors include Positive Temperature Coefficient (PTC) thermistors and Negative Temperature Coefficient (NTC) thermistors. The temperature sensor made of the NTC thermistor is widely applied to household appliances such as water heaters, water dispensers, dish washing machines, disinfection cabinets, dryers and the like, and the principle of the temperature sensor is that the resistance value rapidly decreases along with the temperature rise.

The food processor is usually controlled to supply power by the touch and the match of a microswitch and a rotary buckle on the cup cover, when the cup cover is buckled in place, the rotary buckle reaches a set trigger position, the microswitch is triggered to electrify the machine, so that the motor drives the stirring device to rotate to stir dough, and the heating device generates heat to bake the dough. In the use of cooking machine, because agitating unit's rotation makes the bowl cover rotate easily, the spinner probably breaks away from the trigger position of settlement along with the bowl cover rotation, and then leads to the micro-gap switch disconnection, causes the improper outage stop work of cooking machine, in addition, rotates the bowl cover in the operation of cooking machine accidentally and also can lead to cooking machine stop work.

CN103565301A discloses an electric food processor. The electric food processor comprises a pot body, a handle, a pot body cover, a machine body provided with a microswitch, a first rod piece, a base fixed at the bottom of the pot body, a second rod piece and a third rod piece. When the pedestal mounting was on the organism and the handle was fixed on the pot body, thereby cover the locking on the pot body with pot body through rotatory fixture block that makes the pot body cover on getting into the handle, pot body lid can make first member downstream by the upper end of pressing down first member, the lower extreme of first member can promote the second member to the base is outer when downstream, the one end that makes the second member is outstanding the base and the one end that promotes the third member, thereby the other end of third member reverse movement presses micro-gap switch simultaneously and makes its switch-on. The stirring blade set of the electric food processor disclosed in CN103565301A is directly driven to rotate by a driving motor. Since the rotation speed of the driving motor is large, there may be a case where the torque is insufficient when stirring foods having strong adhesiveness like dough. Therefore, it is often necessary to reduce the rotational speed and increase the drive torque by means of a transmission.

CN109758006A discloses a food processor. The food processor comprises a cup body, a cup cover rotatably buckled on the cup body, a handle, a machine body, a driving motor positioned in the machine body, a belt wheel transmission mechanism and a stirring knife group positioned in the cup body. The belt wheel transmission mechanism comprises a small belt wheel, a belt, a large belt wheel and a transmission wheel. The small belt wheel drives the large belt wheel to rotate through the belt, so that the rotating speed of the driving motor is reduced to a certain extent, and the torsion is increased. However, the individual pulley drive is prone to problems of uneven rotational speed due to belt slip.

The prior technical schemes can not prevent the cup cover from accidentally rotating in the running process of the machine to cause the machine to stop working, thereby bringing inconvenience in use. Furthermore, a single pulley drive may suffer from insufficient torque due to belt slip.

It is therefore desirable to provide a food processor that overcomes the above-mentioned disadvantages.
