Abstract
An electric pressure cooker with improved pressure control comprises a middle cover, an electric heating disc and a control device. The electric heating disc is provided with an electrode and a guide column, a guide column hole is arranged on a bottom plate of the middle cover, and the guide column extends out of the middle cover via the guide column hole. The electric pressure cooker is characterized by further comprising a coil which is wound into the shape of a barrel, the coil is connected with the control device, and one end of the coil is fixed on a support while the other end is opposite to the lower end of the guide column. By aid of the structure, the bottom plate of the middle cover and the electric heating disc move downwards when the inside of the cooker achieves certain pressure, as inductance of the coil is changed, the control device acts to cut off power, and then the electric pressure cooker is in a pressure maintaining state. When the pressure inside the cooker is reduced, the guide column is far away from the coil, and then power is turned on. When in pressure detection and control, a CPU of the control device can detect pressure value through variation of a pressure switch, and then operation of a main circuit is controlled according to pressure values. The electric pressure cooker overcomes shortages that the pressure switch is hard to be regulated and value of a pressure valve is single during usage.
Description
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 comprises shell, base, middle cover, electric hot tray, Kick type temperature detect switch (TDS), Kick type pressure switch and control device, electrode, lead are arranged on the lower surface of electric hot tray, lead hole, electrode pass the hole on the base plate of middle cover, and lead stretches into middle cover by the lead hole; The Kick type pressure switch is fixed in the drain pan by a support, and support is fixedlyed connected with drain pan or middle cover, and the Kick type temperature detect switch (TDS) is fixed on the support; The Kick type temperature detect switch (TDS) cooperates with lead.Existing problems are: Kick type pressure switch pressure threshold value is single and non-adjustable, and can have a strong impact on production efficiency because of regulating pressure switch when producing in enormous quantities.
Summary of the invention
The purpose of this utility model is: provide a kind of improvement pressure controlled electric pressure cooking saucepan, it not only can realize the control of variable pressure threshold values, but also can significantly reduce the debug time of pressure switch when producing, and carries with regard to production efficiency.
The utility model is achieved in that the pressure controlled electric pressure cooking saucepan of a kind of improvement, comprises middle cover, electric hot tray and control device; Electrode, lead are arranged on the electric hot tray, the lead hole is arranged on the base plate of middle cover, lead is cover from stretch out in the lead hole, and its special character is: comprise that also one is wound in the coil of tubular, coil is connected with control device; Coil one end is fixed on the support, and the other end is relative with the lead lower end.
The pressure controlled electric pressure cooking saucepan of described a kind of improvement, its special character is: the lower end of described lead is provided with iron core, and iron core cooperates with coil.
The pressure controlled electric pressure cooking saucepan of a kind of improvement of the utility model owing to adopt such structure, reaches certain pressure in pot, the base plate and the electric hot tray of middle cover move down, because winding inductance quantity changes, are moved by control device, cut off the electricity supply, enter packing state; When the pot inner pressure reduction, lead is then connected power supply away from coil; When pressure detecting and control, the CPU of control device can go the detected pressures value by the variable quantity of pressure switch, and then controls the work of main circuit according to force value; Eliminated in the prior art, in use, pressure switch is regulated difficulty, the defective that pressure threshold value is single.
Description of drawings
Fig. 1 is a cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, cover 1 during the pressure controlled electric pressure cooking saucepan of a kind of improvement comprises, electric hot tray 21 and control device; Electrode 22, lead 21 are arranged on the electric hot tray 2, lead hole (not indicating among the figure) is arranged on the base plate 11 of middle cover 1, lead 21 covers 1 from stretch out in the lead hole, comprise that also one is wound in the coil 3 of tubular, and coil 3 is connected with control device;
The lower end of described lead 21 is provided with iron core 5, and iron core 5 cooperates with coil 3.
Claims (2)
