Description
Technical field
The utility model belongs to the small household appliances technical field, relates in particular to a kind of electric pressure cooking saucepan, is specially the pressure control structure of electric pressure cooking saucepan.
Background technology
At present, electric pressure cooking saucepan obtains being extensive use of of people with its characteristics easily and fast.The pressure type control formula electric pressure cooking saucepan of prior art, its implementation mainly is by the distortion generation displacement of the flexible member between pot and the outer pot in being installed in and converts electronic signal to, be sent in the circuit board controller, controller inductive displacement signal, the working condition of control panel plate, thus reach pressure controlled purpose.
Yet can there be following shortcoming in this class formation:
1. be the displacement transferring elements with the electric hot plate, heating board can deform in the course of the work, and therefore, resulting displacement is that interior pot displacement adds the electric hot plate deflection in the actual pressure control, makes pressure control produce certain deviation;
2. outer pot bears very big pressure, and the outer pot material is a general steel plate, and intensity is relatively poor, therefore all increases outer pot intensity to strengthen thickness usually, has increased cost.
Summary of the invention
The purpose of this utility model is to provide a kind of electric pressure cooking saucepan, the displacement when adopting pot pressurized in directly detecting, and the pressure when working in the pot is controlled more exactly, and pressure control is accurate, does not increase cost.
For achieving the above object, the technical scheme that provides of the utility model is:
A kind of electric pressure cooking saucepan includes shell and the loam cake that is fastened on described shell upper, is provided with steel lid in the described loam cake, is provided with an outer pot in the described shell; Place pot in the described outer pot inner chamber, the inner edge periphery of steel lid is provided with a seal, and described steel lid is fastened and connected with outer pot, and described steel lid, seal, interior pot three constitute a seal cavity; One electric hot plate is positioned at the bottom of described pot; Wherein, described electric pressure cooking saucepan also comprises more than one flexible member and more than one electric hot plate elastic supporting member for supporting optical member; Between pot flange and the outer pot flange, described electric hot plate elastic supporting member for supporting optical member was installed between electric hot plate bottom and the outer pot, and electric hot plate is played the resiliency supported effect in described flexible member was installed in; In the space that described steel lid and shell form, also be provided with the pressure sensor of a detectable described flexible member displacement, described pressure sensor detects the displacement of flexible member, and convert in the circuit board chip that electronic signal is sent to electric pressure cooking saucepan, the circuit board chip is judged the pressure in pot this moment, with the duty of control electric hot plate.
Described electric hot plate elastic supporting member for supporting optical member is a kind of electric hot plate spring.
The beneficial effects of the utility model are as follows:
A kind of electric pressure cooking saucepan of the present utility model is owing to comprise more than one flexible member and more than one electric hot plate elastic supporting member for supporting optical member; Between pot flange and the outer pot flange, described electric hot plate elastic supporting member for supporting optical member was installed between electric hot plate bottom and the outer pot, and electric hot plate is played the resiliency supported effect in described flexible member was installed in; Described steel lid fastens in the space that forms with outer pot, also is provided with a pressure sensor of surveying described flexible member displacement.
When not having pressure in the pot, described electric hot plate is fixing under the supporting role of electric hot plate spring, and electric hot plate and interior pot are fitted fully, and described flexible member in the raw strain does not take place at this moment.
When producing pressure in the pot, interior pot overcomes the elastic force of electric hot plate spring under pressure, does a certain amount of displacement downwards, and can produce the flexible member below the pot flange in being installed in to the power that presses down this moment; Simultaneously, steel covers under the effect of pot inner pressure and moves up, until closely fastening with outer pot.At this moment, because outer pot is fixed, and flexible member has the trend that relative outer pot moves down under the effect of interior pot applied force, therefore flexible member can reach equilibrium of forces by the certain displacement of its strain generation, simultaneously, be installed in the displacement that pressure sensor between electric hot plate and the outer pot obtains flexible member, and convert electronic signal to and be sent in the circuit board chip, judge the pressure in pot this moment, with the duty of control electric hot plate, thereby reach the purpose of controlled pressure.
Therefore, a kind of electric pressure cooking saucepan of the present utility model, advantage is:
1. pot displacement, controlled pressure more exactly in can directly detecting;
2. can avoid outer pot to bear big pressure;
3. simple in structure, realize the production in enormous quantities of electric pressure cooking saucepan easily.
