Abstract
The utility model relates to a control circuit of electric pressure cooker, including temperature fuse, heater, pressure switch, temperature limiter, temperature fuse, heater, pressure switch, temperature limiter establish ties in proper order and constitute control circuit, characterized by still includes manual reset kick formula temperature controller, manual reset kick formula temperature controller with control circuit establishes ties mutually. The utility model discloses an increase manual sudden strain of a muscle formula temperature controller that resets in current electric pressure cooker's control circuit, neither influence the normal work of electric pressure cooker, can in time cut off control circuit under the unusual circumstances appears in electric pressure cooker work again, the work of stopping the heater is unlikely to cause the injury to the user because of temperature and pressure rise unusually in the pot, and fail safe nature is high.
Description
Technical field
The utility model relates to the control circuit of electric pressure cooking saucepan, especially a kind of control circuit with electric pressure cooking saucepan of function of safety protection.
Background technology
The pressure control of existing most of electric pressure cooking saucepans is through the break-make of pressure switch heater to be controlled, and then realizes the control to pressure.But when the electric pressure cooking saucepan operation irregularity, for example pressure switch lost efficacy, and then the control circuit of existing electric pressure cooking saucepan can not be controlled heater, therefore also just can not play real security protection effect, made existing electric pressure cooking saucepan have potential safety hazard.
Summary of the invention
The technical problem that the utility model will solve is the deficiency that overcomes prior art, and a kind of security protection control circuit of electric pressure cooking saucepan more reliably is provided, and under the situation of operation irregularity appears in electric pressure cooking saucepan, can not damage the user guaranteeing.
The technical scheme that realizes the utility model purpose is:
A kind of control circuit of electric pressure cooking saucepan; Include Thermal Cutoffs, heater, pressure switch, temperature limiter; Said Thermal Cutoffs, heater, pressure switch, temperature limiter are followed in series to form control circuit; It is characterized in that, also comprise the hand-reset Kick type temperature controller, said hand-reset Kick type temperature controller and said control circuit are in series.
Realize the in good time control to electric pressure cooking saucepan in order accurately to detect kettle temperature, said hand-reset Kick type temperature controller is located on the electric pressure cooking saucepan pot cover, or is located on the main temperature controller of electric pressure cooking saucepan, or be located on the outer pot and press close in the position of pot.
For fear of the influence of said hand-reset Kick type temperature controller to the electric pressure cooking saucepan operate as normal, the control temperature of said hand-reset Kick type temperature controller is higher than the control temperature of said temperature limiter.
The control temperature of said hand-reset Kick type temperature controller is between 115 ° of C～140 ° C, and when the temperature that records reached this control temperature, the hand-reset Kick type temperature controller was jumped disconnected.
Above-mentioned heater is electric hot tray or electromagnetic induction heat-generating disc.
The utility model compared with prior art; Its beneficial effect is that through increase hand-reset Kick type temperature controller in the control circuit of existing electric pressure cooking saucepan, and the control temperature of hand-reset Kick type temperature controller is higher than the control temperature of temperature limiter; In the time of can guaranteeing the electric pressure cooking saucepan operate as normal; Do not receive the influence of hand-reset Kick type temperature controller, can occur in time cutting off control circuit under the unusual situation in electric pressure cooking saucepan work again, stop the work of heater; Be unlikely to because of kettle temperature and pressure anomaly raise the user to be damaged, security reliability is high.
Description of drawings
Fig. 1 is the sketch map of the control circuit of the utility model electric pressure cooking saucepan.
The specific embodiment:
Embodiment 1:
As shown in Figure 1, in the present embodiment, electrical pressure cooker control circuit is composed in series by Thermal Cutoffs 1, heater 2, pressure switch 3, temperature limiter 4 successively, and hand-reset Kick type temperature controller 5 is connected in the electrical pressure cooker control circuit.Hand-reset Kick type temperature controller 5 is arranged on perception kettle temperature on the electric pressure cooking saucepan pot cover.
Described hand-reset Kick type temperature controller 5 is a prior art, and its concrete structure repeats no more.
During the electric pressure cooking saucepan operate as normal, when pressure that pot inner pressure is set greater than pressure switch 3, pressure switch 3 actions are cut off the electricity supply, and heater 2 quits work.When the electric pressure cooking saucepan operation irregularity, pot inner pressure rises, even the pressure that pressure is set greater than pressure switch 3; When pressure switch 3 is also no longer moved; Pressure can continue to rise, and between 115 ° of C～140 ° C of kettle temperature arrival, hand-reset Kick type temperature controller 5 breaks off; Cut off the electricity supply, heater stops heating.Must carry out hand-reset to hand-reset Kick type temperature controller 5 before user's working voltage power next time pot.
Embodiment 2:
What present embodiment and embodiment 1 were different is: said hand-reset Kick type temperature controller 5 is positioned on the electric pressure cooking saucepan master temperature controller.
Embodiment 3:
What present embodiment and embodiment 1 were different is: said hand-reset Kick type temperature controller 5 is positioned on the electric pressure cooking saucepan outer pot and presses close to the position of pot.
Claims (5)
1. the control circuit of an electric pressure cooking saucepan; Include Thermal Cutoffs (1), heater (2), pressure switch (3), temperature limiter (4); Said Thermal Cutoffs (1), heater (2), pressure switch (3), temperature limiter (4) are followed in series to form control circuit; It is characterized in that, also comprise hand-reset Kick type temperature controller (5), said hand-reset Kick type temperature controller (5) is in series with said control circuit.
2. the control circuit of electric pressure cooking saucepan according to claim 1; It is characterized in that; Said hand-reset Kick type temperature controller (5) is located on the electric pressure cooking saucepan pot cover, or is located on the main temperature controller of electric pressure cooking saucepan, or be located on the electric pressure cooking saucepan outer pot and press close in the pot the position.
3. the control circuit of electric pressure cooking saucepan according to claim 1 is characterized in that, the control temperature of said hand-reset Kick type temperature controller (5) is higher than the control temperature of said temperature limiter (4).
4. the control circuit of electric pressure cooking saucepan according to claim 3 is characterized in that, the control temperature of said hand-reset Kick type temperature controller (5) is between 115 ° of C～140 ° C.
5. according to the control circuit of the arbitrary described electric pressure cooking saucepan of claim 1 to 4, it is characterized in that said heater (2) is electric hot tray or electromagnetic induction heat-generating disc.
