Description
Technical field
The utility model relates to pressure cooking appliance, especially a kind of pressure controlled electric pressure cooker.
Background technology
Present commercially available electric pressure cooking saucepan, mostly be pressure-controlled structure greatly, promptly heat-generating disc and outside flexible member is set between the pot bottom, normally used flexible member comprises elastic plate, disk spring etc., the electric pressure cooking saucepan of this structure is when work, the elastic force that pressure promotion heat-generating disc in the pot courage overcomes flexible member produces displacement downwards, thereby touch the pressure-detecting device action that is arranged on outer pot bottom, after control device detected the signal of telecommunication that pressure-detecting device sends, the output control signal was adjusted culinary art pressure in pot courage by the heating power that changes heat-generating disc.The pot of electric pressure of the type normally will on heat-generating disc, be provided with install leg with outside pot bottom fix (as Chinese patent CN200420068021.9, dish spring fixed structure shown in the patent name " a kind of electric pressure cooking saucepan "), firmly lock in order to make heat-generating disc and outer pot bottom, avoid the heat-generating disc move left and right, normally when design, make end face and outer pot bottom surface that leg is installed keep certain clearance to make heat-generating disc locking, but adopt this structure not only can cause outer pot bottom in the locking process, under the effect of coupling mechanism force, to produce distortion, and can make flexible member under the effect of coupling mechanism force, produce a predeformation, influence the pressure measurement precision of pressure-detecting device.This in addition electric pressure cooking saucepan in use for some time, outer pot bottom can produce a plastic deformation, if when initially installing, the less fixed structure of heat-generating disc that then can make of coupling mechanism force returns pine, cause heat-generating disc rocking in outer pot, fixed structure returns Song Houhui and causes installing leg and big with the gap change of outer pot bottom.
The utility model content
For overcoming the deficiencies in the prior art, it is a kind of simple in structure, safe and reliable that the utility model provides, and the little pressure controlled electric pressure cooker of pressure-detecting device alignment error.
In order to reach above-mentioned technical purpose, the utility model has adopted following technical proposals:
A kind of pressure controlled electric pressure cooker, comprise pot cover, pot courage, outer pot and heat-generating disc, described pot courage places on the heat-generating disc, be provided with resilient supporting unit between described heat-generating disc and the outer pot bottom, described heat-generating disc is provided with the mounting column that heat-generating disc is connected to outer pot bottom, by locking device and cooperating of mounting column heat-generating disc, resilient supporting unit being locked to outer pot bottom, be provided with dish-shaped pad between described outer pot bottom and the locking device, described dish-shaped pad is provided with a plurality of spline tooths.
Described spline tooth points to dish-shaped pad center position, and described spline tooth and locking device contact.
The dish-shaped dorsad pad center position of described spline tooth, described spline tooth and outer pot bottom connection touch.
Described locking device comprises studs and locking nut, and one of described studs directly is locked on the mounting column, and lock described dish-shaped pad by locking nut the other end.
Be provided with many group resilient supporting units between described heat-generating disc and the outer pot bottom, described resilient supporting unit comprises elastic plate and base.
Compared with prior art, the beneficial effects of the utility model are:
1, by a plurality of spline tooths being set, effectively reduced the compression strength of dish-shaped pad, when locking heat-generating disc and outer pot, avoided outer pot bottom and elastomer generation predeformation, influenced the pressure measurement precision at dish-shaped pad.
2, owing to the dish-shaped pad compression strength that is provided with spline tooth is lower, so the initial assemblage gap of dish-shaped pad can be amplified, avoid too small because of assemblage gap, cause the accessory requirement on machining accuracy too high, influence the production efficiency of accessory, reduced production cost.
Description of drawings
Fig. 1 is a scheme of installation of the present utility model.
Fig. 2 is the partial enlarged drawing of A among Fig. 1.
Fig. 3 is the structural representation of dish-shaped pad.
Among the figure:
1, sealing ring; 2, pot cover; 3, pot courage; 4, outer pot; 5, heat-generating disc; 51, mounting column; 6, studs; 7, elastomer; 8, supporting seat; 9, dish-shaped pad; 10, locking nut; 11, pressure switch.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing:
A kind of as shown in Figure 1 pressure controlled electric pressure cooker comprises pot cover 2, pot courage 3, outer pot 4, be provided with sealing ring 1 at pot courage 3 and 2 on pot cover, pressure chamber to pot cover 2 and 3 in courage of pot in cooking process seals, the below of pot courage 3 is provided with heat-generating disc 5, heat-generating disc 5 is provided with the mounting column 51 that heat-generating disc 5 is connected to outer pot 4 bottoms, below mounting column 51, be provided with resilient supporting unit, described resilient supporting unit comprises elastomer 7 and supporting seat 8, elastomer 7 is installed on the supporting seat 8, below mounting column 51, also be provided with locking device, by cooperating of locking device and mounting column 51 with heat-generating disc 5, resilient supporting unit is locked to outer pot 4 bottoms, described locking device comprises studs 6 and locking nut 10,6 one of described studs pass elastomer 7 and supporting seat 8 is locked on the mounting column 51, the other end is passed outer pot 4 bottoms and dish-shaped pad 9 and is passed through locking nut 10 lockings, the spline tooth of described dish-shaped pad 9 points to dish-shaped pad 9 center positions, spline tooth and locking device contact during locking, and supporting surface contacts with outer pot 4 bottoms; Be provided with pressure switch 11 in outer pot 4 bottoms, detect the displacement of heat-generating disc 5 during work.
Present embodiment is when assembling, at first 6 one of studs are fastened on the mounting column 51, then elastomer 7 and supporting seat 8 are inserted on the studs 6 successively, outer pot 4 bottoms are passed in the other end of studs 6, and be inserted in dish-shaped pad 9, with locking nut 10 lockings.
