Description
Technical field
The utility model relates to electric pressure cooking saucepan, especially a kind of pressure controlled electric pressure cooker.
Background technology
In the prior art, the control of the course of work of electric pressure cooking saucepan is to adopt temperature or two kinds of control modes of pressure basically.Adopting the electric pressure cooking saucepan of temperature control mode, is to choose temperature in the electric pressure cooking saucepan course of work as control signal, with the corresponding parameter of Pressure/Temperature, implements a kind of technical scheme to the working condition control of pressure cooker with the temperature value simulation of confirming.This scheme is subjected to the combined influence factor too much owing to need accurately to simulate the interior actual pressure value that takes the dish out of the pot at the temperature value of entity; As sampled point whether rationally, the factor affecting such as variation of pot internal burden, make its control accuracy low, so electric pressure cooking saucepan does not in the market generally adopt temperature control mode with respect to pressure control form.What generally adopt at present is pressure controling mode, promptly utilizes it to produce the corresponding relation of displacement because of pressure, converts pot inner pressure to displacement earlier, utilize this displacement drive votage control switch then, the action of generation opened/closed, thereby the duty of control heat-generating disc realize the pressure height in the control pot.This control model is because the relative Temperature Control Type of precision is higher, and device is simple, and reliability, durability are all more satisfactory, so be widely used.But this technical scheme has been owing to still passed through the process of pressure signal to the displacement signal conversion, rather than directly controlled the course of work of electric pressure cooking saucepan by pressure signal, so the precision of its control still is restricted.
The utility model content
The purpose of this utility model is the shortcoming that overcomes existing electric pressure cooking saucepan, provide a kind of member succinct, control precision height, good reproducibility, not influenced by temperature deviation, really realize pressure controlled pressure controlled electric pressure cooker.
The technical scheme that realizes the utility model purpose is: the utility model comprises pot cover, outer pot, interior pot, electric heat-generating disc and is fixed on control circuit board on the shell, be connected with the control button on the control circuit board, on pot cover, be provided with the through hole of pot in being communicated to, being fixed with pressure responsive element on the through hole seals through hole, pressure responsive element is connected with central processing unit (CPU) on the control circuit board by signal transmssion line, central processing unit is connected with power board by signal transmssion line, and power board is connected with electric heat-generating disc.
In order to make the pressure samples in the pot more accurate, above-mentioned pressure responsive element adopts silicon sensor, the back side of silicon sensor is downwards towards interior pot, allow the pressure of monitoring be applied directly on the pressure chip back side, sensor wafer senses the variation of pressure and it is transferred to central processing unit and handles.
For the instant force value that monitors in the utility model can also being shown take the dish out of the pot, realize that the electric pressure cooking saucepan pot inner pressure is visual, on control circuit board, also be connected with pressure, time display screen.Like this, pressure sensor senses to pressure change and to export instant electrical quantity incessantly, receive by central processing unit and handle, after central processing unit was handled by the formula of compiling and editing, exportable signal drove display screen, display screen can show the instant pressure in taking the dish out of the pot.
Can also realize that in order to make the utility model operating pressure is adjustable, cooking time is adjustable, control button on control circuit board includes pressure, time set button, can be by button according to user's concrete culinary art needs, operating pressure value and cooking time in the pot are set, the utility model can be according to force value, and the setting value of cooking time is implemented the automatic control to heat-generating disc work.
The beneficial effects of the utility model are: owing to adopt silicon sensor direct sensing pot inner pressure, and pass through the course of work of central processing unit electronic control voltage power pot, therefore, its pressure controling precision height, good reproducibility; Display screen can directly show the instant force value in the pot, has realized that pressure is visual; Simultaneously, also be connected with pressure, time set button on the control circuit board, can operating pressure value and cooking time in the pot be set according to user's concrete culinary art needs, realize adjustable in pressure by button.The function of this adjustable in pressure can derive the function that a kind of other control model can't be accomplished---and according to different cooking needs, the pressure of different periods changes before and after realizing in a cooking flow process, to satisfy the need of best cooking effect.
Description of drawings
