Abstract

A pressure switching device for an electric pressure cooker comprises a sealing cavity (1) and an electric heater (6), wherein the sealing cavity (1) is formed by an inner pot (2), a pressure cooker lid (3) and a sealing ring (4), and the electric heater (6) can heat the inner pot (2). A pressure-limiting valve (5) is mounted on the pressure cooker lid, and an exhaust vent (7) communicated with the sealing cavity, a sealing cover (8) and an exhaust vent sealing ring (9) are arranged. Through the adoption of the devices, the electric pressure cooker can be made to work in two pressure states, when the sealing cover (8) is opened, steam is exhausted from the exhaust vent (7), the inner portion of the cooker is in a micropressure state, and the cooker can be used for food easy to cook thoroughly; when the sealing cover (8) is closed, the pressure in the cooker reaches a fixed value, the pressure-limiting valve works, and the inner portion of the cooker is in a high pressure state. The purpose of pressure switching is achieved.

Description

The electric pressure cooking saucepan pressure conversion device
Technical field
The utility model relates to a kind of pressure conversion device of electric pressure cooking saucepan
Background technology
Electric pressure cooking saucepan is greatly favored by consumers as a kind of energy-efficient product, the structure of various control pot inner pressures also occurred, but all is confined to precisely control the higher limit (high pressure) of pot inner pressure.Its weak point is: when cooking rice, pressure can elevate the temperature, and to be directed at the rice nutrition leak more; Pressure-acting makes the soft not mouthfeel that affects of rice, to wait after cooked after its pressure release just can uncap edible; Make general family all have electric cooker and two kinds of devices of electric pressure cooking saucepan, cause the wasting of resources simultaneously.
Summary of the invention
In order to overcome above-mentioned shortcoming, the utility model patent provides a kind of pressure conversion device simple in structure, allows electric pressure cooking saucepan can be operated in high pressure and two kinds of pressure states of minute-pressure.
The technical scheme addressed the above problem is (referring to implementing illustration): the utility model comprises the annular seal space (1) be comprised of interior pot (2), pressure cooker cover (3), sealing ring (4), and the electric heater (6) that internally pot heats, pressure limiting valve (5) is housed on pressure cooker cover, it is characterized in that: a steam vent be communicated with annular seal space (7) is set, dismountable seal cover (8) and steam vent sealing ring (9).
Operation principle of the present utility model is: when seal cover (8) while opening, after annular seal space (1) is heated up by electrical heating, steam is directly discharged from steam vent (7), and now the insufficient pressure of annular seal space is so that pressure limiting valve (5) work, in pot substantially in minute-pressure or atmospheric pressure state; When seal cover (8)) while locking, steam vent (7) is in sealing, and the pressure in annular seal space (4) is when reaching certain value, and pressure limiting valve (5) is started working, handle high voltages state in pot.
The beneficial effects of the utility model are directly to utilize opening and closing of steam vent top cover labyrinth, and the pressure in the controlled pressure pot is operated in the two states of high pressure and minute-pressure, reach the purpose of pressure conversion, and simple and practical property is strong.

The specific embodiment
The present embodiment 1(is shown in Fig. 1, Fig. 2)
This routine annular seal space 1 is comprised of interior pot 2, pressure cooker cover 3, sealing ring 4, and interior pot 2 is contained in shell 11, and steam vent 7 is housed on pressure cooker cover, and steam vent top is provided with dismountable seal cover 8 and steam vent sealing ring 9, and its bottom is provided with anti-overflow device 10.
This routine operation principle is: under the electrical heating condition, if seal cover 8 and steam vent sealing ring 9 are opened, the steam in annular seal space is directly discharged from steam vent 7, and annular seal space internal pressure deficiency is so that pressure limiting valve 5 is worked, and the pressure in annular seal space is in minute-pressure; If seal cover 8 and steam vent sealing ring 9 are closed, steam vent is fully in closed state, and the sealing cavity temperature raises, and pressure increases, and when pressure reaches certain value, pressure limiting valve 5 is started working, and gastronomical process is in high pressure conditions.Reach the purpose of pressure conversion.
Embodiment 2(Fig. 3)
This routine structure is basic identical with embodiment 1, and just the bottom of steam vent 7 is threaded, and through pot cover 3, pad 13, with nut 12, is connected.
The steam vent of embodiment 1 is connected as a single entity with pot cover, has the characteristics of good airproof performance, and example 2 adopts screw thread, nut, and pad is connected in pot cover, although number of fitting parts increases, the production technology of pot cover has been simplified.

Claims (3)

1. electric pressure cooking saucepan pressure conversion device, comprise the annular seal space (1) formed by interior pot (2), pressure cooker cover (3), sealing ring (4), and the electric heater (6) that internally pot heats, pressure limiting valve (5) is housed on pressure cooker cover, it is characterized in that: a steam vent be communicated with annular seal space (7) is set, seal cover (8) and steam vent sealing ring (9).
