Abstract
The utility model relates to an electric pressure cooker, including pot cover, face lid, sealing washer, interior pot, outer pot, heater, pressure control device and heating circuit, be equipped with the sealing washer between pot cover and the interior pot, pot cover, sealing washer, interior pot constitute sealed cavity, and the position between pot bottom and the outer pot is arranged in to the heater, its characterized in that be equipped with pressure relief device on the sealed cavity, pressure relief device includes pressure release window, dog and sealing washer, and in the pressure release window was arranged in to the dog, was equipped with the sealing member between dog and the pressure release window, keeps being connected through interference fit between dog and the sealing washer. When the electric pressure cooker works abnormally, the pressure in the cooker rises, the pressure control device fails, the pressure in the cooker continues to rise, when the pressure in the cooker reaches a set value for pressure relief of the pressure relief device, the stop block is separated from the sealing piece and the sealing cavity under the action of the pressure in the cooker, steam in the cooker is exhausted from the pressure relief window, pressure relief is realized, and the use safety of the electric pressure cooker is ensured.
Description
Technical field
The utility model relates to electric pressure cooking saucepan, especially a kind of electric pressure cooking saucepan with function of safety protection.
Background technology
It is the break-make realization through pressure control device control heater circuit that the pressure of existing most of electric pressure cooking saucepans is controlled, but when the electric pressure cooking saucepan operation irregularity, for example: pressure control device lost efficacy; Pot inner pressure increases; For this reason, the electric pressure cooking saucepan product is typically provided with pressure relief devices such as pressure limiting valve, and this type of device adopts elongated shaft-like blast pipe usually; This structure existence is prone to blocked shortcoming; When the blocked inefficacy of this type of pressure relief device, pot inner pressure can not in time be discharged, and has very big potential safety hazard.
Summary of the invention
The technical problem that the utility model will solve is the deficiency that overcomes prior art, and a kind of security protection electric pressure cooking saucepan more reliably is provided.
The technical scheme that realizes the utility model purpose is:
A kind of electric pressure cooking saucepan; Comprise pot cover (1), cover (2), sealing ring (3), interior pot (4), outer pot (5), heater (6), pressure control device and heater circuit; Be provided with sealing ring (3) between pot cover (1) and the interior pot (4), pot cover (1), sealing ring (3), interior pot (4) constitute sealed cavity, and heater (6) places the position between interior pot (4) bottom and the outer pot (5); It is characterized in that; On said sealed cavity, be provided with pressure relief device, said pressure relief device comprises pressure release window (7), block (8) and seal (9), and block (8) places in the pressure release window (7); Be provided with seal (9) between block (8) and the pressure release window (7), keep being connected through interference fit between block (8) and the seal (9).
Said block (8) is provided with groove (81), and seal (9) is provided with bulge loop (91), and bulge loop (91) is stuck in the groove (81), and block (8) is fixed in the pressure release window (7).
Said pressure release window (7) is arranged on the pot cover (1).
Said pressure release window (7) is arranged on the interior pot (4).
Said pressure release window (7) is arranged on interior pot (4) sidewall.
Above-mentioned pressure release window (7) is a through hole.
During operate as normal, the break-make of controlling heater circuit through pressure control device realizes the control to pot inner pressure.
During the electric pressure cooking saucepan abnormal work, pot inner pressure raises, and pressure control device lost efficacy; Pot inner pressure continue to rise, when pot inner pressure during greater than the setting value of said pressure relief device, block (8) under the effect of pot inner pressure with seal (9) and seal chamber disengaging; Get into the cavity between sealed cavity and the pot body; Steam is discharged from pressure release window (7) in the pot, realizes that pressure discharges, and guarantees the safe in utilization of electric pressure cooking saucepan.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
The specific embodiment:
Embodiment 1:
As shown in Figure 1: a kind of electric pressure cooking saucepan; Comprise pot cover 1, cover 2, sealing ring 3, interior pot 4, outer pot 5, heater 6, pressure control device and heater circuit; Be provided with sealing ring 3 between pot cover 1 and the interior pot 4; Pot cover 1, sealing ring 3, interior pot 4 constitute sealed cavity, the position in heater 6 places between pot 4 bottoms and the outer pot 5.Pot cover 1 is provided with pressure relief device, and said pressure relief device comprises the pressure release window 7 that is opened on the pot cover 1, and block 8 places in the pressure release window 7, is provided with seal 9 between block 8 and the pressure release window 7.Block 8 is provided with groove 81, and seal 9 is provided with bulge loop 91, and bulge loop 91 is stuck in the groove 81, and block 8 is fixed in the pressure release window 7.Said pressure release window 7 is for being located at the through hole on the pot cover 1.
The force value of breaking off heater circuit during the pressure control device operate as normal begins the pairing force value of pressure release less than pressure relief device.
During the electric pressure cooking saucepan operate as normal, when pot inner pressure reaches the force value of pressure control device disconnection heater circuit, break off heater circuit, stop heating, realize control pot inner pressure through pressure control device.
During the electric pressure cooking saucepan abnormal work, pot inner pressure raises, when pot inner pressure reaches the force value of pressure control device disconnection heater circuit; Heater circuit can not break off, and pot inner pressure continue to rise, when pot inner pressure reaches said pressure relief device and begins the pairing force value of pressure release; Block 8 breaks away from seal 9 and seal chamber under the effect of pot inner pressure, gets into the cavity between pot cover 1 and the cover 2, and steam is discharged from pressure release window 7 in the pot; Get into the cavity between pot cover 1 and the cover 2; Discharge through the gap between pot cover 1 and the cover 2 then, realize the safe release of pot inner pressure, guarantee the safe in utilization of electric pressure cooking saucepan.
Embodiment 2:
As shown in Figure 2, the difference of present embodiment and embodiment 1 is, on the sidewall of pot 4, promptly is on the sidewall of interior pot 4, through hole to be set in pressure release window 7 is located at.During the electric pressure cooking saucepan abnormal work, pot inner pressure raises, when pot inner pressure reaches said pressure relief device and begins the pairing force value of pressure release; Block 8 breaks away from seal 9 and seal chamber under the effect of pot inner pressure; Cavity between interior pot 4 of entering and the outer pot 5, steam is discharged from the cavity between pressure release window 7 entering pot interior pot 4 and the outer pot 5 then in the pot; Realize the safe release of pot inner pressure, guarantee the safe in utilization of electric pressure cooking saucepan.
