Technical Field
The utility model relates to the field of rice cooker working circuits of electric rice cookers, in particular to a novel mechanical electric rice cooker working circuit.
Background
In the current mechanical electric rice cooker, after the electric rice cooker finishes the heating work, the temperature limiter is mainly used for controlling. When the electric cooker works, alternating current 220V voltage is applied to the heating plate through the power switch, the heating plate heats, the inner cooker starts to cook rice, and meanwhile, a heating indicator lamp in the electric cooker is on. When the rice is cooked, the electric cooker contains a certain amount of heat. At this time, the temperature will stay at the boiling point until the temperature in the electric cooker will rise again after the water evaporates. When the temperature rises above 100 ℃, the temperature sensing magnetic steel in the magnetic steel temperature limiter loses magnetism, the permanent magnet is released, and the permanent magnet enables the rice cooking switch to be disconnected through the lever, but the magnetic steel temperature limiter is easy to damage in the actual use process, so that the heat preservation effect of the electric rice cooker is poor.
The utility model adopts a new circuit structure form, and improves the heat preservation effect of the electric cooker through the combination of the kick temperature controller and the temperature control switch.

The utility model provides a novel mechanical rice cooker cooking circuit. The beneficial effects are as follows:
the surface in the middle of the bottom of the inner container of the electric cooker is always contacted with the surface of a kick type temperature controller (normally closed type) assembled in the middle of a heating disc, the temperature of the bottom of the inner container is always transmitted to the kick type temperature controller, alloy metal sheets in the kick type temperature controller deform after being subjected to certain temperature, and the contact points are pushed away to lead to circuit disconnection, so that the heat insulation circuit with a heat insulation plate begins to work, the heat insulation plate is assembled on the heating disc to form a heat insulation relationship, the temperature of the heating disc can slowly decline to be lower than the kick temperature of the kick type temperature controller after the heating disc is not heated, the kick type temperature controller is closed again, the heating disc still can not be heated at the moment, the maintained heat insulation relationship is unchanged, the arrangement avoids the damage of the traditional electric cooker due to the magnetic steel temperature limiter, the continuous heating of the heating disc, and heat insulation of the traditional electric cooker can not be realized after cooked rice.
Drawings
Fig. 1 is a schematic diagram of a cooking circuit of an electric rice cooker according to the present utility model.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Examples of embodiments are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements throughout or elements having like or similar functionality. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.
Referring to fig. 1, after a temperature control switch S2 (rice cooking switch) is pressed after the novel mechanical electric cooker is electrified to form a loop, a heating disk R1 of the electric cooker starts to generate heat and the temperature continuously rises, a ZSD1 indicator lamp is turned on, the heating disk surface contacts with the bottom surface of the inner container, the temperature is conducted to the inner container to enable the temperature of the inner container to rise, rice and water are contained in the inner container, the temperature of the heated rice and water of the inner container rises to about 100 degrees and boils, at the moment, the temperature of the bottom of the inner container is about 102 degrees, the temperature is maintained for a period of time, until the temperature of the bottom of the inner container continuously rises to about 160 degrees after water is boiled, the surface in the middle of the bottom of the inner container is always contacted with the surface of a kick temperature controller S1 (normally closed) assembled in the middle of the heating disk, the temperature of the bottom of the liner is always transmitted to the kick temperature controller S1, so that the surface of the kick temperature controller basically reaches 160 degrees after the temperature of the bottom of the liner reaches 160 degrees, an alloy metal sheet in the liner deforms and pushes away a contact after receiving a certain temperature to lead to circuit disconnection, at the moment, a normal current passes through a PTC heating element R2 connected with the kick temperature controller S1 in parallel, the PTC heating element R2 rapidly heats, the temperature rises to about 10 seconds to exceed 80 degrees, the PTC heating element R2 is assembled and contacted with a temperature control switch S2 (a rice cooking switch), the temperature is transmitted to the temperature control switch S2, and after the temperature control switch S2 receives the temperature of about 80 degrees, the alloy metal sheet in the liner deforms and pushes the switch to cut off the power.
