Abstract
The utility model relates to a safe electric pressure cooker, including the pot body and pot cover, pot and outer pot in the internal pot that is equipped with of pot, in outer pot was arranged in to interior pot, the below of interior pot was equipped with the heater, and interior pot seals its characterized in that through the sealing washer with the pot cover: the pot cover is provided with a thermal fuse which is connected with the pressure control circuit. The utility model discloses a measure the temperature of pot cover and set up temperature fuse on the pot cover, can guarantee the electric pressure cooker normal during operation, can appear again in the electric pressure cooker work when the unusual rising of interior pot temperature appears under the unusual circumstances, realize opening circuit between temperature fuse and the pressure control circuit to 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 electric pressure cooking saucepan, and especially a kind of safety electric pressure cooker when the pressure-regulating device of electric pressure cooking saucepan lost efficacy, can carry out safeguard protection to electric pressure cooking saucepan.
Background technology
The pressure control of existing most of electric pressure cooking saucepans realizes through dual mode: first kind is pressure-regulating device to be set (for example: pressure switch) heater is controlled, and then realized the control to pressure below interior pot.When the electric pressure cooking saucepan operation irregularity, for example pressure-regulating device lost efficacy, and can not control heater, also just can not carry out pressure control effectively; Second kind is mechanical pressure limiting device to be set (for example: protective devices such as pressure limiting valve, float-controlled valve, safety valve) realize pressure control on pot cover; But mechanical pressure limiting device is not connected with control circuit; When mechanical pressure limiting device lost efficacy, can not carry out pressure control effectively to electric pressure cooking saucepan.This dual mode all can not play real security protection effect when appearance is unusual, make 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 safety electric pressure cooker 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 safety electric pressure cooker; Comprise pot body and pot cover, pot and outer pot in being provided with in the pot body, interior pot places in the outer pot; The below of interior pot is provided with heater; Interior pot seals through sealing ring with pot cover, and it is characterized in that: on pot cover, be provided with temperature fuse, temperature fuse is connected with pressure control circuit.
The said temperature fuse is arranged on the upper surface of pot cover.
Above-mentioned heater is electric hot tray or electromagnetic induction heating dish.
Heater broke off the temperature that sets when the fusing-off temperature of said temperature fuse was higher than the electric pressure cooking saucepan operate as normal.
Be fixed with drive rod below the above-mentioned heater, be provided with the pressure switch that is connected with pressure control circuit under the drive rod.
Be fixed with pressure sensor on the above-mentioned pot cover, be connected among the pot and with control circuit in pressure sensor stretches into.
The fusing-off temperature of said temperature fuse is 115 ℃～140 ℃.
The utility model compared with prior art, its beneficial effect is, the temperature through measuring pot cover also is provided with temperature fuse on pot cover; In the time of can guaranteeing the electric pressure cooking saucepan operate as normal; In the time of again can pot temperature raises unusually in occurring under the unusual situation appears in electric pressure cooking saucepan work, realization be opened circuit between temperature fuse and the pressure control circuit, thereby stops 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 structural representation of the embodiment 1 of the utility model electric pressure cooking saucepan;
Fig. 2 is the structural representation of the embodiment 2 of the utility model electric pressure cooking saucepan.
The specific embodiment:
In the following example, temperature fuse 5 adopts thermal cut-off.
Embodiment 1:
As shown in Figure 1, comprise pot body and pot cover 3, pot 1 and outer pot 2 in being provided with in the pot body, interior pot 1 places in the outer pot 2, and the bottom surface of interior pot 1 has heater 6, and in the present embodiment, heater 6 adopts electric hot tray; Interior pot 1 seals through sealing ring 4 with pot cover 3, on the upper surface of pot cover 3, is provided with thermal cut-off 5, and thermal cut-off is connected with pressure control circuit, and the fusing-off temperature of thermal cut-off is 125 ℃; Be fixed with drive rod 7 below the above-mentioned heater 6, be provided with the pressure switch 8 that is connected with pressure control circuit under the drive rod 7; Temperature when pressure switch is disconnected is set at 115 ℃.
When the pressure cooker operate as normal; As long as temperature reaches 115 ℃; Pressure switch 8 is promptly broken off by the drive rod 7 that increases to bottom offset because of pressure; Temperature on the pot cover 3 does not reach 125 ℃ of the fusing-off temperatures of thermal cut-off, so thermal cut-off can not fuse, and can guarantee that the operate as normal of electric pressure cooking saucepan is unaffected; Occur under the unusual situation in electric pressure cooking saucepan work, when temperature reaches 115 ℃, pressure switch 8 can not broken off by drive rod 7 yet; Pot 1 temperature anomaly raises in occurring, when temperature is increased to 125 ℃, and thermal cut-off fusing; Realize opening circuit between itself and the pressure control circuit; Thereby stop the work of heater 6, be unlikely to because of kettle temperature and pressure anomaly raise the user to be damaged, security reliability is high.
Embodiment 2:
As shown in Figure 2, the difference of present embodiment and embodiment 1 is, is fixed with pressure sensor 9 on the above-mentioned pot cover 3, is connected among the pot 1 and with control circuit in pressure sensor 9 stretches into.The fusing-off temperature of thermal cut-off is 130 ℃; Temperature when pressure sensor 9 orders about control circuit disconnection heater 6 is set at 115 ℃.
When the pressure cooker operate as normal; As long as temperature reaches 115 ℃; Pressure sensor 9 promptly sends a signal to control circuit heater 6 is broken off; And the temperature on the pot cover 3 does not reach 130 ℃ of the fusing-off temperatures of thermal cut-off, so thermal cut-off can not fuse, and can guarantee that the operate as normal of electric pressure cooking saucepan is unaffected; Occur under the unusual situation in electric pressure cooking saucepan work, when temperature reaches 115 ℃, heater 6 also can not broken off by the control circuit; Pot 1 temperature anomaly raises in occurring, when temperature is increased to 130 ℃, and thermal cut-off fusing; Realize opening circuit between itself and the pressure control circuit; Thereby stop the work of heater 6, be unlikely to because of kettle temperature and pressure anomaly raise the user to be damaged, security reliability is high.
