Abstract
The invention relates to a non-self-resetting control device for an electric pressure cooker. The non-self-resetting control device is characterized by comprising a bracket, a normally-closed microswitch, a pressure plate, a push rod arranged on a heating plate, an elastic tongue piece and a resetting push rod, wherein the normally-closed microswitch is fixed at the lower part of the bracket; one end of the pressure plate is fixedly connected with an outer shell of the normally-closed microswitch, the other end of the pressure plate is hung in the air, and the pressure plate is matched with buttons of the microswitch; the upper end of the elastic tongue piece is fixed on the bracket, the lower end of the elastic tongue piece is hung in the air and is matched with the pressure plate; one end of the resetting push rod is fixedly connected with the elastic tongue piece, the other end is an operation end; and the lower end of the push rod is matched with the pressure plate. The control device has the following work principle: (1) when the cooker achieves set pressure, the pressure plate is matched with the buttons of the normally-closed microswitch, then the lower end of the elastic tongue piece is pressed on the pressure plate, the power is cut off, and heating is stopped, so that the purpose of stopping heating before pressure release is realized; (2) a pressure release valve is omitted; and (3) power can be cut off even under the condition that a microcomputer is damaged or the pressure release valve is damaged, so that safety is guaranteed.
Description

The present invention be achieved in that a kind of electric pressure cooking saucepan can not Self-resetting control device, its special character is: it comprises support, normally closed type microswitch, pressing plate, is arranged on push rod, the elastic tongue piece on heat-generating disc and the push rod that resets,
The support bracket fastened bottom of described normally closed type microswitch, described pressing plate one end is fixedly connected with shell with the normally closed type microswitch, the other end is unsettled, and pressing plate coordinates with the button of microswitch;
It is unsettled and coordinate with pressing plate that the upper end of described elastic tongue piece is fixed on the support upper and lower end; The end of push rod of resetting is fixedly connected with elastic tongue piece, and the other end is the operating side;
The lower end of described push rod coordinates with pressing plate.
Described a kind of electric pressure cooking saucepan can not Self-resetting control device, its special character is: the bottom bending of described elastic tongue piece, the lower end of bending part coordinates with pressing plate.
Described a kind of electric pressure cooking saucepan can not Self-resetting control device, its special character is: a pilot hole is arranged on described support, and elastic tongue piece coordinates with pilot hole.
Described a kind of electric pressure cooking saucepan can not Self-resetting control device, its special character is: a pilot hole is arranged on described support, and elastic tongue piece coordinates with pilot hole.
Described a kind of electric pressure cooking saucepan can not Self-resetting control device, its special character is: described support comprises upper board, connecting plate and lower panel, described upper board is parallel with lower panel;
Described pilot hole connects upper board, connecting plate and lower panel.
A kind of electric pressure cooking saucepan of the present invention can not Self-resetting control device, owing to adopting such structure, (1) reach setting pressure in pot, push rod presses down pressing plate, pressing plate coordinates with the button of normally closed type microswitch, the lower end of elastic tongue piece is pressed on pressing plate thereupon, and cuts off the electricity supply, stopped heating; Thereby realize before pressure release stopped heating; (2) be to save relief valve; (3) when micro computer damage or relief valve damage, also may cut off the power supply, guarantee safety.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 2, Figure 3, Figure 4, a kind of electric pressure cooking saucepan can not Self-resetting control device, it comprises support 1, normally closed type microswitch 2, pressing plate 3, is arranged on push rod 4, the elastic tongue piece 5 on heat-generating disc and the push rod 6 that resets,
The bottom of described normally closed type microswitch 2 fixed supports 1, described pressing plate 3 one ends are fixedly connected with shell with normally closed type microswitch 2, the other end is unsettled, and pressing plate 3 coordinates with the button of microswitch 2;
It is unsettled and coordinate with pressing plate 3 that the upper end of described elastic tongue piece 5 is fixed on support 1 upper and lower end; The end of push rod 6 of resetting is fixedly connected with elastic tongue piece 5, and the other end is the operating side;
The lower end of described push rod 4 coordinates with pressing plate 3.
The bottom bending of described elastic tongue piece 5, the lower end of bending part 51 coordinates with pressing plate 3.
One pilot hole 11 is arranged on described support 1, and elastic tongue piece 5 coordinates with pilot hole 11.
Described support 1 comprises upper board 1A, connecting plate 1B and lower panel 1C, upper board 1A, connecting plate 1B and lower panel 1C is one-body molded makes; Described upper board 1A is parallel with lower panel 1C; Upper board 1A and lower panel 1C have a segment distance between the projection on horizontal plane.
Described pilot hole 11 connects upper board 1A, connecting plate 1B and lower panel 1C.
The present invention as shown in Figure 6, is connected in circuit in use.
Original state as shown in Figure 5, pressure rise in pot, electric hot tray moves down, be arranged on the push rod 4 on electric hot tray, act on pressing plate 3, pressing plate 3 acts on the button of normally closed type microswitch 2 and cuts off the power supply, the bending part 51 of the side of pressing plate 3 and elastic tongue piece 5 is slidably matched and enters in pilot hole 11 when forcing elastic tongue piece 5, when pressing plate 5 moved to the lower end of elastic tongue piece 5 and leaves, elastic tongue piece 5 resetted, and the lower end of elastic tongue piece 5 acts on pressing plate 3; Even push rod 4 resets, the lower end of elastic tongue piece 5 still acts on pressing plate 3; When pot inner pressure reaches safe pressure, but hand by the push rod 6 that resets, shell fragment tongue piece 5 enters in pilot hole 11 on support, separate with pressing plate the lower end of elastic tongue piece 5, at this moment, state is as shown in Figure 5.
