Description
Technical field
The utility model relates to household appliance technical field, relates in particular to a kind of electric cooker.
Background technology
Kitchen appliance--electric cooker just in the consumer pursues more good days, has got into huge numbers of families stealthily.Electric cooker is called grill pan again, is to utilize electric energy to change the cooker of heat energy into, and is easy to use, sanitation and hygiene, also have to food steam, boil, stew, multiple operating function such as stewing.Common electric cooker is divided into insulation self-action, regularly three types of heat preserving type and novel micro computer controlled standards.Become daily household electrical appliance now, the invention of electric cooker has reduced a lot of families and has spent in the time on cooking.
Electric cooker generally is divided into 2 kinds: a kind of is the heat preserving type auto-electric cooker using pottery, automatic heat preserving when meal boils; Another kind is the timing auto-electric cooker using pottery, controls automatically by the time of having a meal and cooks.The auto-power-off device of electric cooker is a sensing magnet steel switch, when meal is ripe, and 100 ℃ of sensing magnet steel losss of excitation of temperature and cutting off the power supply.Mi Wei has water to continue boiling when boiling into meal in pot, and temperature can not surpass 100 ℃, and sensing magnet steel can loss of excitation, so switch on all the time.
In order to keep temperature, rice is cooled off fully after existing this type electric cooker finishes when cooking, electric hot tray can continue to be incubated heating with insulation power usually; Sometimes the user cooks a lot, once eats up, and a large amount of rice of residue forget simultaneously when pulling out power supply that electric cooker will continue to carry out heat insulation work, has wasted power supply in the pot for cooking rice, and long-time unnecessary heat insulation work also can influence the service life of electric cooker.
Summary of the invention
The utility model technical problem to be solved provides a kind of self-shield electric cooker of uncapping, and realizes the monitoring to the top cover state through a ball, and simple in structure, reliable operation can effectively avoid when electric cooker is opened, still being in heating work.
The utility model is achieved in that a kind of self-shield electric cooker of uncapping, and comprises pot body, top cover, pot for cooking rice and PLC controller, is provided with a cavity in pot body; The cavity open top, said pot for cooking rice is placed in the cavity, and the cavity inner bottom part is equipped with electric hot tray; The end face of electric hot tray and the pig of pot for cooking rice, PLC controller control connection electric hot tray, said pot body is provided with buckle; Described top cover one end is hinged on pot body top through axle, and the top cover other end is provided with the draw-in groove that matches with buckle, and the top cover lower surface is provided with a circle sealing ring; Sealing ring matches with pot for cooking rice, is provided with steam vent in the middle of the top cover, and said top cover is provided with compensating groove; Compensating groove radially is arranged in the top cover with respect to jointed shaft; Be placed with ball in the compensating groove, said compensating groove is provided with breaker point near the bottom surface of jointed shaft one end, and said breaker point links to each other with the PLC controller.
Described compensating groove is total a pair of, the parallel both sides that are symmetricly set on top cover of pair of balanced groove.
On described pot body handle is housed also, said handle is the U-shaped handle, and two summits of U-shaped handle are hinged on respectively on the outer wall of pot body both sides.
The utility model self-shield electric cooker of uncapping can be oppressed breaker point through a ball when top cover is opened, make the PLC controller receive the signal deenergization; Simple in structure, reliable operation can effectively be avoided when electric cooker is opened, still being in heating work, has practiced thrift electric energy, has application value widely.
Description of drawings
Fig. 1 is the utility model self-shield electric cooker structural representation of uncapping;
Fig. 2 is the utility model top cover of self-shield electric cooker view when opening of uncapping.
Among the figure: 1 pot body, 2 top covers, 3 pots for cooking rice, 4 buckles, 5 sealing rings, 6 steam vents, 7 compensating grooves, 8 balls, 9 breaker points, 10 handles.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Like Fig. 1, shown in 2, a kind of self-shield electric cooker of uncapping comprises pot body 1, top cover 2, pot for cooking rice 3 and PLC controller; Be provided with a cavity in pot body 1, the cavity open top, said pot for cooking rice 3 is placed in the cavity; The cavity inner bottom part is equipped with electric hot tray, the pig of the end face of electric hot tray and pot for cooking rice 3, PLC controller control connection electric hot tray; Said pot body 1 is provided with buckle 4, and described top cover 2 one ends are hinged on pot body 1 top through axle, and top cover 2 other ends are provided with the draw-in groove that matches with buckle 4; Top cover 2 lower surfaces are provided with a circle sealing ring 5, and sealing ring 5 matches with pot for cooking rice 3, is provided with steam vent 6 in the middle of the top cover 2; Said top cover 2 is provided with compensating groove 7, and compensating groove 7 radially is arranged in the top cover 2 with respect to jointed shaft, is placed with ball 8 in the compensating groove 7; Said compensating groove 7 is provided with breaker point 9 near the bottom surface of jointed shaft one end, and said breaker point 9 links to each other with the PLC controller.
