CN201641582U - An electric pressure cooker with improved buffer device - Google Patents

Abstract

An electric pressure cooker with an improved buffer device comprises an outer cover and an electric heating plate, wherein a boss protruding from the outer surface to the inner surface is arranged on a bottom plate of the outer cover, and a circular hole is formed in the boss; the electric heating plate is provided with at least three supporting seats which are uniformly arranged in a circular shape; still include at least three elastic strip, the contained angle between two adjacent elastic strip equals, and the elastic strip is fixed on the bearing, and the elastic strip both ends support the cooperation each other with boss and brace table respectively. By adopting the structure, when the inner container sinks when certain pressure is reached in the cooker, the elastic lath can better play a role of buffering, the sensitivity is high, and the deformation of the inner cover can be effectively prevented; the arrangement of the lug boss can effectively disperse stress; compared with the prior art, the buffer disc is changed into the elastic lath, so that the material is saved.

Description

A kind of electric pressure cooking saucepan that improves buffer unit

Technical field

The utility model relates to a kind of electric pressure cooking saucepan.

Background technology

Present prior art, a kind of electric pressure cooking saucepan, comprise outer cover, buffering disk and electric hot tray, the temperature controller installing hole, the joint pin that are positioned at the center are arranged on the electric hot tray, the base plate of outer cover and circumferential wall intersection have the brace table of at least three protruding from outside to inside rounded arrangements, and there is a circular hole at the center of buffering disk and base plate; Electric hot tray is fixed on the base plate of outer cover by joint pin; The buffering disk is arranged on the brace table, and the buffering disk is fixedlyed connected with the base plate of outer cover.Existing problems are: (one) is that the buffering disk area is big, waste material; (2) be poor sensitivity.

Summary of the invention

The purpose of this utility model is: a kind of electric pressure cooking saucepan that improves buffer unit is provided, and it is not only easy to assembly, economical with materials; And highly sensitive, reply action soon.

The utility model is achieved in that a kind of electric pressure cooking saucepan that improves buffer unit, comprise outer cover and electric hot tray, the temperature controller installing hole, the joint pin that are positioned at the center are arranged on the electric hot tray, the base plate of outer cover and circumferential wall intersection have the brace table of at least three protruding from outside to inside rounded arrangements, and there is a circular hole at the center of base plate; Electric hot tray is fixed on the base plate of outer cover by joint pin; Its special character is: the base plate of described outer cover have one from outer surface to the protruding boss of inner surface, circular hole is positioned on the boss;

At least three rounded evenly distributed supporting bases are arranged on the described electric hot tray; Also comprise at least three elastic slats, the angle between adjacent two elastic slats equates that elastic slat is fixed on the supporting base, and the elastic slat two ends are supported mutually with boss and brace table respectively and cooperated.

Described a kind of electric pressure cooking saucepan that improves buffer unit, its special character is: described elastic plate is rectangle or the annulus arc.

A kind of electric pressure cooking saucepan that improves buffer unit of the utility model, the base plate of described outer cover have one from outer surface to the protruding boss of inner surface, circular hole is positioned on the boss; At least three rounded evenly distributed supporting bases are arranged on the described electric hot tray; Also comprise three elastic slats, the angle between adjacent two elastic slats equates that on the elastic slat fixed mounting base, the elastic slat two ends are supported mutually with boss and brace table respectively and cooperated.Owing to adopt such structure, in pot, reach certain pressure, when inner bag sank, elastic slat can be brought into play cushioning effect better, and was highly sensitive, can prevent effectively that inner cover from deforming; The setting of boss is dispersive stress effectively; Compared with prior art, change elastic slat into, saved material by the buffering disk.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As Fig. 1, Fig. 2, shown in Figure 3, a kind of electric pressure cooking saucepan that improves buffer unit comprises outer cover 1 and electric hot tray 2, the temperature controller installing hole 21, the joint pin 22 that are positioned at the center are arranged on the electric hot tray 2, the base plate of outer cover 1 and circumferential wall intersection have the brace table 11 of three protruding from outside to inside rounded arrangements, and there is a circular hole 12 at the center of base plate; Electric hot tray 2 is fixed on the base plate of outer cover 1 by joint pin 22 usefulness screws 3, and the bottom of outer cover also is fixed with support 4; The base plate of described outer cover 1 have one from outer surface to the protruding boss 13 of inner surface, circular hole 12 is positioned on the boss 13;

Three rounded evenly distributed supporting bases 23 are arranged on the described electric hot tray 2; Also comprise three elastic slats 5, the angle between adjacent two elastic slats 5 equates that elastic slat 5 is screwed on supporting base 23, and elastic slat 5 two ends are supported mutually with boss 13 and brace table 11 respectively and cooperated.

Described elastic slat 5 is rectangle or the annulus arc.

Above-described only is preferential embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is considered as protection domain of the present utility model.
