Abstract

An electric rice cooker with an internal dark-red pottery pot is composed of a plastic stand with quickly heating fan, circuit board, power socket and air exhausting holes, a casing with control panel and water cup, an internal metallic container with heating disc on its bottom, an internal dark-red pottery pot on said heating disc with top cover, a pressure spring for said heating disc, and a plastic top cover with a steam valve. Its advantages are high heating speed, correct temp and low cost.

Description

A kind of electric cooker structure with red-clay inner vessel

Technical field:

The present invention relates to the kitchen utensils technical field, refer in particular to a kind of electric cooker structure with red-clay inner vessel.

Background technology:

Because it is natural pollution-free that the red-clay inner electric cooker has, the characteristics of safe easy cleaning are accepted by increasing people.But heat transfer is slow, power consumption is big because red-clay inner owing to the attribute of material itself, also has, the inaccurate shortcoming of thermometric.And because the limitation that boccaro adopts handicraft to produce, ubiquity size inaccuracy, the shortcoming that tolerance is big.

Summary of the invention:

The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and have heating soon, thermometric standard, and the relative electric cooker structure with red-clay inner vessel that reduces of production cost.

Solution proposed by the invention is as follows: on the bottom plastic base of electric cooker, fast Hot-air fan is installed, and wiring board, wiring board pillar and power-line plug, there is several rows of wind hole at place, position, plastic feet limit; On plastic feet, place the electric cooker shell, control panel and water tumbler are installed on it; Enclosure is a metal inner tube, and the bottom in the metal inner tube is a heat-generating disc, places red-clay inner on the heat-generating disc, and red-clay inner comprises a boccaro top cover; At place, heat-generating disc pin position, compression spring is installed.The top of meal pot shell is the plastics covers; Plastic cover covers a projecting part minute-pressure steam valve is installed.Compared with prior art, the present invention has following beneficial effect: (1) is owing to having adopted the inner bag spring structure, and is lower to the size tolerance requirements of inner bag.Production cost is relatively low relatively.(2) fast Hot-air fan structure has been adopted in the bottom, and the thermal efficiency increases.(3) meal pot has adopted minute-pressure formula steam valve structure at header field, and except the efficiency of heating surface improved relatively, the rice that cooks was soft more good to eat.

Description of drawings:

Fig. 1, Fig. 2 are the structural representations of one embodiment of the invention.

Fig. 3 is Fig. 1, the inner bag bottom upward view of new structure shown in Figure 2.

Fig. 4 is Fig. 1, the plastic feet vertical view of new structure shown in Figure 2.

Fig. 5 is a minute-pressure steam valve enlarged drawing shown in Figure 2.

The specific embodiment:

By following embodiment the present invention is further elaborated:

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, one embodiment of the invention structurally is divided into plastics cover 4, meal pot shell 2 and base 1 three parts.The plastics cover 4 of described boccaro electric cooker has a steam valve 5.Steam valve 5 is made of withstand voltage spring 19, balancing weight 20, steam valve lower cover 21 and steam valve silica gel sheet 22.Its structure belongs to the separable structure of unpicking and washing.Metal aperture 18 is arranged at described electric cooker metal inner tube 7 bottoms.11 places, described heat-generating disc 9 pin positions are equipped with compression spring 10.Strengthen the use tolerance factor of red-clay inner, made production cost reduce relatively.Electric cooker plastic bottom cover 1 is equipped with fast Hot-air fan 16.Its effect is that the heat that will be produced in pot body course of work transmits to heat-generating disc 9 bottoms again, reaches conserve energy and heats effect efficiently.The screw foot 13 that electric cooker plastic bottom cover 1 is installed wiring board 14 belongs to increases design.Its effect be with wiring board 14 unsettled after, the air quantity that can make fast Hot-air fan 16 produce blows wiring board 14 inside.The effective depth of screw foot 13 is in 10mm to the 40mm scope.Electric cooker plastic bottom cover 1 has several rows of wind hole 12.

The present invention is placed on food in the Boccaro cooker courage 8 of meal pot earlier in use.After covering boccaro lid 6 and plastics cover 4, after the function of selection control panel 17, electric cooker is started working.After the heat-generating disc in the metal inner tube 79 began to send certain heat, the red-clay inner 8 that is contacted above the heat-generating disc 9 began to receive heat, and food in effect pot.In the time of the work of heat-generating disc 9, the fast Hot-air fan 16 in the plastic bottom cover 1 of electric cooker begins from pot body outside exhausting in meal pot.The heat that this moment, meal pot was produced in the course of the work, the wind-force that a part is produced by fast Hot-air fan 16 discharges by vent 12.And a part of heat is transmitted to heat-generating disc 9 by the metal aperture 18 of fast Hot-air fan 16 below metal inner tube 7, makes the thermal effect that adds of heat-generating disc 9 be improved.When electric cooker work certain hour, the temperature in pot is raised to a certain degree, and the pressure in pot begins to increase.After the pressure in pot rose to greater than withstand voltage spring 19 holding capacity in the steam valve on the plastics cover 45, the balancing weight 20 in the steam valve 5 is jack-up upwards, and discharges unnecessary vapor pressure.Thereby make meal pot keep the minute-pressure state in the course of the work all the time.The water content and the mellowness that cook the rice that takes like this are all better than existing boccaro meal pot, and firing rate is faster.

The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
