As shown in Figure 1, heater (2) has a mesopore, and the temperature-sensitive part of temperature controller (1) is in mesopore, and interior pot (3) is placed on the heater.In order to make temperature controller can better experience interior cooking bottom temperature, the pot the bottom of a pan in the pipe face of temperature controller is close to.Available for this reason spring part cooperates temperature controller above the high from heater core of pipe face, not push down temperature control organ pipe face after interior pot puts in when interior pot puts in.Temperature controller can have multiple mode, temperature controller of the present invention can adopt suitable existing product, the inventor has invented two kinds of simple and effective temperature controllers, a kind of is the mode that adopts liquid thermal expansion or gas increased by thermal pressure, as shown in Figure 2, make the interior filled with fluid of liquid storage tube (26) of suitable shape or adorn the lower liquid of a certain amount of boiling point, liquid storage tube connects bellows sheet (27), deciding frame (24) is close on liquid storage tube, the bellows sheet has a push rod (23) in the middle of the outside, push rod is changeable, decide to fix on the frame microswitch, microswitch has spring leaf (22), and spring leaf has contact (29) to contact with the contact of another sheet metal, and the connection heater is drawn by lead (28) in the contact.The contact is normally closed at ordinary times.Spring leaf is made definite shape and is made that the contact can disconnect by jumping when being pressed to a certain degree downwards when push rod (push rod and the insulation of bellows sheet), closes in push rod semi-coast contact great-jump-forward again.Spring leaf is regulated temperature when changing contact switch and jump by set screw (30), the elasticity of spring leaf also can be without set screw with other modes such as regulating with eccentric mode.For easy, the unite title of usefulness " set screw " of this paper replaces.The bellows sheet also can directly not be connected on the liquid storage tube and can

of bellows sheet Yin Wendu, can make the plastic deformation that definite shape is protected the bellows sheet deciding frame.The pot the bottom of a pan in the liquid storage tube face is close to.When reaching about 115 ℃, temperature (can change temperature) by the elasticity of adjusting set screw, heated liquid expands or low-boiling point liquid produces high-pressure gas, promoting the bellows sheet protrudes downwards, the downward top of push rod spring leaf (22) is beated spring leaf suddenly, the contact disconnects, heating stops, and interior pot temperature descends, bellows sheet retraction.When push rod reduces top pressure spring sheet pressure after to a certain degree, spring leaf jumps suddenly and recovers original state and closed again in the contact, and heating restarts.In order to make reset temperature, can use set screw (43) regulating spring sheet near break-off signal.Go round and begin again like this, until till the timer setting-up time.Second kind of temperature controller is the distortion that utilizes bimetal leaf.General bimetallic temperature controller break-off signal is comparatively accurate, but that reset temperature then differs is bigger, does not reach instructions for use.Temperature controller of the present invention requires reset temperature near break-off signal, does a temperature controller with major-minor two bimetal leafs for this reason, and Fig. 3 is a principle schematic.According to the difference of shape, the active layers of two bimetal leafs and passive layer can be in the same way, also can be incorgruous.Fig. 3 is one of them embodiment.The shape that main bimetal leaf (32) upwards bends up in the middle of making, active layers is following, passive layer is last, stator (piece) is arranged below, a hole is arranged in the middle of the main bimetal leaf, pass this hole by supporting grain (36) and hold, spring leaf (33) is arranged above the main bimetal leaf, its right-hand member is fixed, and left end has contact (34), and the corresponding contact of this contact is drawn by lead respectively and connected heater.Spring leaf is in position gone out to lower cam position (37).The auxilliary bimetal leaf (35) of making bending is arranged on spring leaf, and active layers is last, and passive layer is down, and its effect is to reset as early as possible when the contact break-off signal is reduced.Stator (piece) is also arranged above the auxilliary bimetal leaf.The contact is normally closed at ordinary times, and when temperature was elevated to 115 ℃ of left and right sides, main bimetal leaf stretched the salient point of jack-up spring leaf (33), and spring leaf upwards bends up, the unexpected tripping in contact.At this moment auxilliary bimetal leaf (35) also becomes straight; Temperature descends after the contact disconnects, auxilliary bimetal leaf (35) becomes curved, owing to have stator, auxilliary bimetal leaf to withstand spring leaf (33) downwards to pressing down above it, recover original form with this acceleration spring sheet and closed in the contact, thereby make reset temperature near break-off signal.In order to improve precision, can connect set screw on the stator up and down.(not drawing) for easy figure

The middle pot of above-mentioned Fig. 1 also can be integrated with outer pot, in pot become outer pot.In order to save material, can make middle pot with thin aluminium sheet, corrosion resistant plate or iron plate, and the shape of reinforcement dynamics is made in chimeric position and the bottom of a pan in the upper edge.Can there be the additional even part of fixed seal ring sealing ring and pot cover to be lumped together and take out cleaning easily in the pot cover.Timer can be made button or rotary like that as electric cooker, can preset regularly.Thermal cut-off, warmer etc. can be arranged.Temperature controller of the present invention can be to fix it after product regulates, and also can be to change heating-up temperature by adjusting set screw at any time according to the food situation.In order to increase function, the present invention also can replace temperature controller regulation and control kettle temperature with electronic circuit or computer system or pressure controlling system even with pressure limiting valve when passing over cost.
