Abstract
The invention provides a delayed closing device for an electric pressure cooker. A flexible closing pad with a sealing cavity is arranged on the outlet of an air outlet pipe, a temperature control piece is arranged on the back of the flexible closing pad, a gap for forming a ventilation channel is reserved between the closing portion of the flexible closing pad and the outlet of the air outlet pipe, and the size of the gap is set in the mode that when the set time is up, the flexible closing pad and the temperature control piece encounter thermal deformation and cover the outlet of the air outlet pipe. A spring is connected between the flexible closing pad and the air outlet pipe, and the elasticity of the spring pushes the flexible closing pad to leave the outlet of the air outlet pipe. The delayed closing device has the advantages that a temperature controller is completely isolated from the air, control is executed according to the thermal contraction principle, the spring abuts against the closing pad to control the opening and closing time accurately, and use is safe and reliable.
Description
Technical field

Summary of the invention
Object of the present invention is just to provide a kind ofly and can utilize the shrinkage heat principle that rises to implement to control by temperature controller completely and air insulated, with spring, withstands sealing pad, with the accurate gauge tap time, and safe and reliable electric pressure cooking saucepan time-delay closing device.
Solution of the present invention is such:
A kind of electric pressure cooking saucepan time-delay closing device, this device comprises escape pipe outlet, it is characterized in that: described escape pipe exit is provided with the flexible sealing pad with sealed cavity, flexible sealing pad back is provided with temperature control sheet, between the outlet of the sealing position of described flexible sealing pad and escape pipe, leave the gap that forms venting channels, the size in described gap be set in while reaching setting-up time described in flexible sealing pad and temperature control sheet produce thermal deformation and cover escape pipe outlet; Between flexible sealing pad and escape pipe, be connected with spring, the elastic force of described spring leaves escape pipe outlet for promoting flexible sealing pad.
Technical scheme also comprises more specifically: the formation of described sealed cavity comprises sealing flap and the flexible sealing pad being connected with sealing flap, the periphery of described flexible sealing pad is tightly connected by sealing seat and described sealing flap, and its inner chamber forms described sealed cavity.
Further: described sealing flap is provided with sealed step, in sealed step, place is connected with sealing seat, the periphery of described flexible sealing pad is positioned over sealed step place, be connected with sealing flap above, be connected with sealing seat below, with screw connection structure screwing hermetic flap and sealing seat, by the fastening formation sealed cavity of the periphery of flexible sealing pad.
Further: described flexible gasket is whole band cavity structure, and its cavity forms described sealed cavity.
Further: described flexible sealing pad is a kind of of planar shaped, arc surfaced, spheric, taper for the sealing position that escape pipe outlet is sealed.

The specific embodiment
A kind of electric pressure cooking saucepan time-delay closing device, this device comprises the escape pipe outlet 6 of being fixed on pot cover 1, described escape pipe exports 6 places and is provided with the flexible sealing pad 10 with sealed cavity, flexible sealing pad 10 backs are provided with temperature control sheet 9, between the sealing position of described flexible sealing pad 10 and escape pipe outlet 6, leave the gap that forms venting channels, the size in described gap be set in while reaching setting-up time described in flexible sealing pad 10 and temperature control sheet 9 produce thermal deformations and cover escape pipe outlet 6; Between flexible sealing pad 10 and escape pipe 2, be connected with spring 11, the elastic force of described spring 11 leaves escape pipe outlet 6 for promoting flexible sealing pad 10.
Described sealing flap 7 is provided with sealed step, at sealed step place, be connected with sealing seat 5, the periphery of described flexible sealing pad 10 is positioned over sealed step place, be connected with sealing flap 7 above, be connected with sealing seat 5 below, with screw connection structure screwing hermetic flap 7 and sealing seat 5, by the fastening formation sealed cavity of the periphery of flexible sealing pad 10.
The structure of sealed cavity can be overall structure, and described flexible gasket 10 is made band cavity structure for integral body, and its cavity forms described sealed cavity.
Described flexible sealing pad 10 is for to the escape pipe outlet 6 sealing positions of sealing being a kind of of planar shaped, arc surfaced, spheric, taper.
Temperature control sheet 9 is to be Split type structure with flexible sealing pad 10, and temperature control sheet and flexible sealing pad are placed on sealing seat 5 and seal in flap 7, with buckle, are in clamping connection.
The course of work of the present invention below:
Electric pressure cooking saucepan heating, steam in pot exports 6 by escape pipe, exhaust duct 12 is discharged, steam by time the heat that produces be delivered to flexible gasket 10, the heat producing during heating is delivered to flexible gasket 10 and temperature control sheet 9, air in flexible gasket 10 sealed cavity is below heated to start to splash and rises, the sealing surface that promotes flexible sealing pad 10 exports 6 places towards escape pipe and moves, increase along with the heat time, when temperature reaches design temperature, temperature control sheet 9 produces strain, the sealing surface of flexible sealing pad 10 is pushed up to the position of escape pipe outlet 6, as shown in Figure 2, gas in sealing pot, enter heating and the vexed meal state of pressurize.After heat time finishes, the temperature in pot slowly declines, and the temperature in the sealed cavity after flexible gasket 10 is also followed decline, 9 reinstatements of temperature control sheet, under the elastic force effect of spring 11, the sealing surface that pushes flexible sealing pad 10 is returned to the position of opening escape pipe outlet 6, as shown in Figure 1.
