Abstract

The utility model provides an insulating automatic electric rice cooker made of purple sand. On the basis of the existing structure, the bottom of the internal container and the end surface of the electric hot plate of the electric rice cooker are the horizontal surfaces with good contact performance, and simultaneously, the direct contact between the upper end of a temperature controlled switch and the bottom of the internal container is changed into that the upper end of the temperature controlled switch is directly adpressed with the center of the bottom of the electric hot plate. Thereby, the heat efficiency is enhanced, and simultaneously, the heat-conducting property is also improved. Regardless of adoption of how much volume of cooking rice, the electric rice cooker with the internal container made of purple sand can be controlled well.

Description

Insulating automatic electric rice cooker made of purple sand

The utility model relates to household electrical appliance, particularly a kind of pottery, purple heat preserving type automatic electric rice cooker.

What occur on the market in recent years is the electric cooker of inner bag with pottery, boccaro ware etc., the bottom of its inner bag mostly is arc shaped surface, electric hot plate central authorities are provided with an about hole, garden of 4 to 5 centimeters, and the magnet type temperature detect switch (TDS) passes this hole and directly contacts with the cambered surface of inner bag bottom, thus the temperature in the control the bottom of a pan.But, because the designer does not have really to infer theoretically the thermal conductivity factor of pottery or boccaro ware class inner bag, cause this series products of designing in actual applications, can not be according to a conventional method controlled in volume arbitrarily, and can only in full volume or few volume, could control.For solving its deficiency,, do not reach desirable effect too although in the enforcement of product, adopted various corrective measures.

The purpose of this utility model provide a kind of simple in structure, temperature control effect good, can guarantee that the electric cooker of pottery or boccaro ware class inner bag all can be well controlled in various volumes.

Technical solution of the present utility model is: the inner bag of electric cooker adopts the bottom to make for the pottery of horizontal plane or boccaro ware, for making inner bag and electric hot plate keep well contacting, electric hot plate is made the horizontal plane of central atresia, the pull bar of temperature detect switch (TDS) is connected with lever, its top end face directly is close to the electric hot plate bottom center, the soft magnetism of a heatproof 150 degree to 250 degree is set, to guarantee the curie point control after rice is cooked of its pottery or boccaro ware class inner bag simultaneously in temperature detect switch (TDS).

The utility model has the advantages that: existing electric hot plate is changed system into enclosed horizontal plane, temperature detect switch (TDS) is not directly produced with inner bag to be contacted, but be close to the bottom of electric hot plate, thereby can improve its thermal efficiency greatly, making pottery or boccaro ware is the electric cooker of inner bag, no matter adopts how many volumes to cook, and all can be well controlled, compared with similar products, have advantages such as simple in structure, that enforcement is easy, cost is low, temperature control effect is good.

Below in conjunction with accompanying drawing the utility model is illustrated.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a temperature detect switch (TDS) schematic diagram of the present utility model.

As shown in Figure 1 and Figure 2: this heat preserving type automatic electric rice cooker comprises formations such as pot cover 1, pot body 2, inner bag 3, switch 4, lever 5, bimetal leaf 6, temperature detect switch (TDS) 7 and electric hot plate 8, soft magnetism 9, heating wire 10, insulator 11, its embodiment is: adopting pottery or boccaro ware is inner bag, simultaneously the horizontal plane with good contact is processed in the bottom of inner bag 3, for make inner bag 3 can with electric hot plate between keep well contacting, the end face of electric hot plate 8 is also made horizontal plane.Make former temperature detect switch (TDS) can pass direct contact of electric hot plate like this and become the bottom center of directly being close to electric hot plate with the inner bag bottom.All can keep good switching function for making temperature detect switch (TDS) 7 no matter use to cook under how many volume situations, former heatproof 130 degree in the switch to the soft magnetisms of 150 degree, are become the soft magnetisms of heatproof 150 degree to 250 degree at inner bag.Also can adopt heatproof 150 degree to replace soft magnetism to the Hard Magnetic of 400 degree simultaneously, its temperature-sensitive effect is also good like this.Other embodiment of the present utility model is all same as the prior art.

Claims

1, a kind of pottery, purple heat preserving type automatic electric rice cooker, by pot cover (1), pot body (2), inner bag (3), switch (4), lever (5), bimetal leaf (6), temperature detect switch (TDS) (7) and electric hot plate formations such as (8), it is characterized in that: the bottom of inner bag (3) is horizontal plane, the central atresia of electric hot plate (8), also be horizontal plane, the pull bar of temperature detect switch (TDS) (7) is connected with lever (5), its top end face directly is close to electric hot plate (8) bottom center, and the heatproof that is arranged on the soft magnetism (9) in the temperature detect switch (TDS) (7) is that 150 degree are to 250 degree.

2, automatic electric rice cooker according to claim 1 is characterized in that: available heatproof 150 degree of said soft magnetism (9) to the Hard Magnetic of 400 degree replaces.
