Abstract
The utility model discloses an energy-saving electric pressure cooker based on a microcomputer, which comprises a body, a cover with a limiting pressure relief valve, an inner pot, a heating plate and a microcomputer control circuit. The heating plate is arranged on the bottom in the body, the inner pot is arranged on the heating plate in the body, and a seal ring is arranged between the cover and the body. The energy-saving electric pressure cooker is characterized in that an elastic metal plate is arranged between the heating plate and the bottom surface in the body, and an anti-block cover is arranged in the position with the exhaust port of the limiting pressure relief valve. With the dual overpressure protection through the elastic metal plate and the normally closed pressure switch between the heating plate and the bottom surface in the body, the utility model effectively prevents the risk caused by the overpressure in the cooker, and greatly improves the service safety and reliability. With the anti-block cover in the position with the exhaust port of the limiting pressure relief valve, the utility model can ensure the normal operation of the relief valve. With the opening and closing safety lock catch on the cover, the utility model can ensure that the pressure can not be generated when the cover and the body are not buckled in position, and the cover can not be opened when the pressure exists in the cooker. The utility model also has the advantages of energy conservation, high efficiency and convenient installation.
Description
Technical field
The utility model relates to a kind of kitchen appliance tool, specifically is a kind of micro computer energy-saving voltage power pot.
Background technology
Traditional microcomputer electric pressure cooker has been established pressure-limiting safety valve on pot cover, in the process of using, pressure-limiting safety valve phenomenon of blocking can occur unavoidably, in case the pot internal gas pressure raises, the danger that tends to blast, health of human body and property thereof to the personnel of periphery constitute certain threat, so its security performance can not satisfy requirement used in everyday.In addition, on the pot cover of traditional electric pressure cooking saucepan, do not have the folding secure latch,, under high pressure open pressure cooker, might scald the user in case maloperation appears in the user.
The utility model content
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of efficient energy-saving, easy for installation, safe and reliable micro computer energy-saving voltage power pot.
To achieve these goals, the technical solution adopted in the utility model is: micro computer energy-saving voltage power pot, include a pot body, have the pot cover of pressure-limiting safety valve, interior pot, heat-generating disc, microcomputer control circuit, heat-generating disc is located at the bottom in pot body, interior pot is positioned on the heat-generating disc of pot body, be provided with sealing ring between pot cover and the pot body, it is characterized in that: be provided with elastic sheet metal between the bottom surface in described heat-generating disc and the pot body.
Be connected to pressure sensor in the described microcomputer control circuit, described pressure sensor is located at the below of interior pot and contacts with interior pot bottom.
The exhaust ports of described pressure-limiting safety valve is provided with Anti-stop cover, and described Anti-stop cover is positioned on the inner surface of pot cover.
Described pot cover is provided with the folding secure latch, and described secure latch is the push rod that has back-moving spring that is located on the pot cover by, and be located on pot body and constitute with the corresponding buckling groove of push rod, described push rod is connected in the buckling groove.
Also be connected to the pressure normally closed switch in the described microcomputer control circuit, described pressure normally closed switch is located between heat-generating disc and the pot body bottom surface.
The beneficial effects of the utility model: owing to be provided with the dual overpressure protection of elastic sheet metal and pressure normally closed switch between the bottom surface in heat-generating disc and pot body, the danger of effectively having avoided pot internal cause superpressure to bring has greatly improved the security reliability of using; Because the exhaust ports of pressure-limiting safety valve is provided with Anti-stop cover, guaranteed that safety valve can work normally; Because pot cover is provided with the folding secure latch, guarantee that a pot cover and a pot body fasten can not go up pressure when not in place, can not uncap when in the pot air pressure being arranged; This pressure cooker also has efficient energy-saving, advantage easy for installation.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an internal structure schematic diagram shown in Figure 1.
Among the figure: 1, pot body; 2, pressure-limiting safety valve; 3, pot cover; 4, interior pot; 5, microcomputer control circuit; 6, heat-generating disc; 7, support foot; 8, elastic sheet metal; 9, pressure sensor; 10, Anti-stop cover; 11, push rod; 12, buckling groove; 13, pressure normally closed switch.
The specific embodiment
As shown in Figure 1, 2, micro computer energy-saving voltage power pot, include pot body 1, have the pot cover 3 of pressure-limiting safety valve 2, interior pot 4, heat-generating disc 6, microcomputer control circuit 5, heat-generating disc 6 is located at the bottom in pot body 1, interior pot 4 is positioned on the heat-generating disc 5 of pot body 1, be provided with sealing ring between pot cover 3 and the pot body 1, the double-decker that pot body 1 is made up of shell and internal layer, heat-generating disc is installed on the bottom surface of internal layer, the bottom of heat-generating disc 6 is provided with three support foots 7, and each support foot 7 is fixedlyed connected with elastic sheet metal 8.Be connected to pressure sensor 9 in the microcomputer control circuit, the bottom of pot 4 in described pressure sensor 9 is located at.Also be connected to pressure normally closed switch 13 in the microcomputer control circuit, described pressure normally closed switch 13 is located between heat-generating disc 6 and pot body 1 bottom surface.The exhaust ports of pressure-limiting safety valve 2 is provided with Anti-stop cover 10, and described Anti-stop cover 10 is positioned on the inner surface of pot cover 3.Pot cover 3 is provided with the folding secure latch, and described secure latch is the push rod that has back-moving spring 11 that is located on the pot cover by, and be located on pot body 1 and constitute with the corresponding buckling grooves 12 of push rod 11, described push rod 11 is connected in the buckling groove 12.
Operation principle: in improper use causes pot during superpressure, pot promotion heat-generating disc moved down in pressure forced, occurring under the change in displacement situation, pressure switch deenergization and stop heating, if just in case pressure switch is malfunctioning, pressure continue to increase, heat-generating disc continues to move down, thereby make whole in pot significantly move down and break away from sealing, gas is discharged from the bottom of pot body, formed dual security insurance.Micro computer energy-saving voltage power pot of the present utility model adopts the all-sealed structure design, the hermetically sealed cooking, and food nutrition storage rate height, genuineness, meal matter is soft good to eat.The fuzzy control of utilization micro computer is preset timing function to the temperature and pressure correlation, and countdown automatically behind the setting-up time when countdown is finished, starts heating automatically and starts working.Time-saving energy-saving, thermal efficiency height, pot congee, stew, more than 60%, the working time dwindles 40% than electric cooker power saving in smoldering.
