Abstract
An electric pressure cooker, includes a lid, a body, a base, an inner pot, an outer pot and a heating plate. The lid is hinged to the body and can be fastened with the inner pot or outer pot, the heating plate is elastically mounted at the bottom of the outer pot by a elastic mechanism, the inner pot is placed on the heating plate, several push rods are set at the bottom of the heating plate, at least one push rod is provided with elastic mechanism which is a convex or n-shaped spring sheet placed on the inner bottom of the outer pot, and the top of the spring sheet abuts against the push rod. The outer pot has flush bottom and is connected with the push rods and the spring sheets by screws. The spring sheet has better deformation performance, uniform displacement amount, and easier resetting, so as to realize more precise pressure control of the electric pressure cooker and improve the safety performance of the electric pressure cooker. The electric pressure cooker has simple structure, easy processing and quick assembly, and obtains pressure control function without depending on the elastic deformation of the outer pot in the case of small structural alterations of the existing electric pressure cooker, thus further reducing manufacturing cost of the electric pressure cooker.

Technical field
The utility model relates to a kind of electric pressure cooking saucepan.
Background technology
At present, the electric pressure cooking saucepan that most of families use, its outer pot with interior pot between be generally elasticity and be connected, reach the purpose of its pressure release in use through both displacement, guarantee that it is safe in utilization.Disclose a kind of electric pressure cooking saucepan like Chinese patent document number CN2744266 on December 7th, 2005, be made up of pot cover, interior pot, outer pot, shell, heat-generating disc, elastomer, packing ring and base, interior pot places in the outer pot; Heat-generating disc, elastomer and plain washer are seated between the inside and outside pot; Under the pot, the catch bar on the heat-generating disc passed through hole corresponding on the outer pot, stretches on the movable contact spring of pressure control switch in heat-generating disc placed; Its elastomer is the dish spring; A plurality of dish springs are formed dish spring group with the form of combination, and an end of dish spring group contacts with the plain washer on the heat-generating disc, and the other end contacts with plain washer on the outer pot baseplane; Described heat-generating disc is provided with boss, and boss passes the through hole on dish spring, plain washer and the outer pot, and screw closely links to each other boss with outer pot.The electric pressure cooking saucepan of this structure, part is various, and installation step is many, and production cost is high, and the displacement of interior pot is bigger, and build-up of pressure is controlled phenomenons such as instability easily.Therefore, need further to improve.
The utility model content
The purpose of the utility model aims to provide a kind of simplicity of design, rational in infrastructure, cost of manufacture is low, pressure control is accurate, safe and reliable electric pressure cooking saucepan, to overcome weak point of the prior art.
By a kind of electric pressure cooking saucepan of this purpose design, comprise pot cover, fuselage, base, interior pot, outer pot and heat-generating disc, pot cover is hinged on the fuselage; And can fasten with interior pot or outer pot, heat-generating disc is installed in outer pot bottom through elastic mechanism elasticity, and interior pot places on the heat-generating disc; Its architectural feature is that the bottom of heat-generating disc is provided with several push rods; At least one push rod is provided with elastic mechanism, and said elastic mechanism is to place the spring leaf that is convex or several fonts in the outer pot at the end, spring leaf top and push rod against.
Gapped in said spring leaf and the outer pot at the end.
Said outer pot bottom is concordant, and outer pot is connected with push rod and spring leaf through screw.
Also be provided with pad between said screw and the outer pot outer bottom.
The position in said shim screw hole is provided with upper overturning, the end of upper overturning and spring leaf against.
Between said pad and the spring leaf cushion block is set, the upper and lower side of cushion block respectively with pad, spring leaf against, cushion block is metal derby or silica gel piece.
Said spring leaf is processed by the manganese steel punching press.
Also be provided with relief valve on the said pot cover, heat-generating disc or outer pot bottom are connected with pressure switch.
The utility model is through being provided with spring leaf between the push rod of heat-generating disc and outer pot, the deformation performance of spring leaf is better, the displacement even amount, and it is easier to reset, and makes the pressure control of electric pressure cooking saucepan more accurate, helps improving the security performance of electric pressure cooking saucepan.It has simple in structure, easy to process, assembling characteristics such as convenient simultaneously, under the little situation of the structural modification of existing electric pressure cooking saucepan, no longer relies on the outer pot elastic deformation and obtains pressure controlled function, and the manufacturing cost of electric pressure cooking saucepan is further reduced.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the enlarged drawing at A place among Fig. 1.
Fig. 3 is the structural representation of an embodiment pad.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1-Fig. 3, this electric pressure cooking saucepan comprises pot cover 1, fuselage 6, base 7, interior pot 3, outer pot 4 and heat-generating disc 5; Pot cover 1 is hinged on the fuselage 6, and can fasten with interior pot 3 (or outer pots 4), and heat-generating disc 5 is installed in outer pot 4 bottoms through elastic mechanism elasticity; Interior pot 3 places on the heat-generating disc 5; The bottom of its heat-generating disc 5 is provided with several push rods 11, and the number of present embodiment push rod 11 is three, and at least one push rod 11 is provided with elastic mechanism; Said elastic mechanism is for placing the spring leaf 8 that is several fonts (or convex) in the outer pot 4 at the end, spring leaf 8 tops and push rod 11 against.
Gapped in spring leaf 8 and the outer pot 4 at the end.In the present embodiment, outer pot 4 bottoms are concordant, and outer pot 4 is connected with push rod 11 and spring leaf 8 through screw 10.Also be provided with pad 9 between screw 10 and outer pot 4 outer bottoms.
The position of pad 9 screw holes is provided with upper overturning, and the end of upper overturning and spring leaf 8 are against, the i.e. height of upper overturning, and be consistent with the gap at the ends in spring leaf 8 and the outer pot 4.In pot 3 when receiving high pressure, push rod 11 presses down, and makes spring leaf 8 that elastic deformations take place, interior pot 3 no longer receive high pressure the time, under the effect of spring leaf 8, help push rod 11 and upwards reset.Also can be according to the actual design needs, cushion block (not marking among the figure) is set between pad 9 and the spring leaf 8, the upper and lower side of cushion block respectively with pad 9, spring leaf 8 against, wherein cushion block is metal derby or silica gel piece.Two kinds of technique effects that technical scheme reached are consistent.Above-mentioned spring leaf 8 is processed by the manganese steel punching press, makes it to have better elastic, to meet instructions for use.
