The plunger packing 166 is elastically installed through the second elastic member 165 to move up and down through the 164a and contacts the outer circumferential side of the through hole 162a formed in the diaphragm 162 at the bottom thereof. The plunger pin 167 and the plunger pin 167 provided in accordance with the central axis of the image It is installed to penetrate the inner lid 120 and the lid case 110 is composed of a pressing pin 168 for pressing the plunger pin 167.

The partition wall 162 is made of a soft material to form a thin film, the plunger packing 166 is a mushroom-shaped inverted form, the center portion is coupled to the lower end of the plunger pin 167, the edge surface is The through hole 162a of the diaphragm 162 is inserted, and the bottom surface of the plunger 161 is caught to block the high temperature and high pressure steam discharged through the steam outlet 131 during cooking. It is composed.

First and second locking jaws 161c and 161d are formed in the housing hollow portion 161a of the valve housing 161 with a step, and an edge portion 164b protrudes from the lower end of the plunger 164. The first elastic member 163 is supported between the edge portion 164b and the first locking jaw 161c, and the edge portion 164b of the plunger 164 is caught by the second locking jaw 161d. The plunger 164 is configured to prevent separation from the housing hollow portion 161a of the valve housing 161.

In addition, a third catching jaw 167a is formed at an upper end side of the plunger pin 167, and a fourth catching jaw 164c is formed at an inner lower end of the plunger hollow portion 164a of the plunger 164. The second elastic member 165 is installed between the third and fourth locking jaws 167a and 164c, and the plunger pin 167 is the plunger hollow portion 161a when the plunger pin 167 is lowered. And to prevent departure from the device.

A screw portion 161f is formed on an outer circumferential surface of the valve housing 161, and a nut portion 133a is provided on an inner wall of the heat sink 130 to screw the screw portion 161f of the valve housing 161. The rib 133 protrudes.

The push pin 168 penetrates the inner lid 120 and the lid case 110 and is installed inside the connection pipe 169 having a hollow shape in which the upper and lower ends thereof are opened, and the upper side thereof. A flange member 168a is formed on the packing member, and a bottom surface of the flange portion 168a is installed between the outer side of the push pin 168 and the connection pipe 169 to block the steam from being discharged to the outside. 171 is installed to be seated on the top surface.

A fifth catching jaw 169a is formed in the upper end of the connecting pipe 169 so that the upper surface of the flange part 168a is caught, and the packing member 171 is disposed at a predetermined position inside the connecting pipe 169. A supporting part 169b supporting the lower end is formed.

The packing member 171 serves to secure the push pin 168 so as to be movable, as well as to perform an airtight role, the upper and lower ends of which are formed to have a thick thickness and are easily fixed. It is made of a soft material formed so as to be thin and contracted and stretched.

Next, the operation principle of the auxiliary steam discharge means 160 to perform the safety device function of the electric pressure cooker according to an embodiment of the present invention configured as described above.

First, after filling a predetermined amount of water and rice in the inner cylinder 11 and seated in the interior of the main body 1 to cover the lid means 100, then press the cooking button to cook.

When cooking is started in a state in which the lid means 100 is covered, the temperature and pressure are increased for a predetermined time, and when the temperature and pressure are sufficiently raised after the passage of time, high-pressure steam is discharged through a steam discharge pipe (not shown). It will cook while keeping the internal temperature and pressure constant.

In such a state, as the diaphragm 162 in close contact with the plunger packing 166 is raised to push up the plunger 164, the plunger 164 is raised to catch the second catching jaw 161d to maintain the elevated state. Thus, the first elastic member 163 maintains a compressed state.

However, in this case, if the steam discharge pipe or solenoid valve not shown during cooking is clogged by rice or foreign matter or the cleaning state is insufficient, the internal pressure continues to rise, which causes the pressure cooker to deform or explode. There is a risk, there is a risk of a safety accident if the user forcibly opens the lid means 100 in such a state.

The present invention is to allow the user to manually discharge the steam when the abnormal high pressure occurs as described above, first, when the user presses the push pin 168, the packing member 171 with the lowering operation of the push pin 168. ) Contracts.

The push pin 168 continues to descend to press the upper end of the plunger pin 166 to lower the plunger pin 167 to release the plunger packing 166 from the bottom of the plunger 161.

As the diaphragm 162 is positioned therebetween, the plunger packing 166, which is in contact with the bottom surface of the plunger 161, is dropped, and a gap is formed, so that the high-pressure steam escapes through the steam outlet 131 and the diaphragm ( Flow through the plunger hollow portion 161a through the through hole 162a of 162 is discharged between the inner lid 120 and the heat dissipation plate 130 to solve the high pressure state inside the inner cylinder (11).

At this time, the high pressure discharged from the inner cylinder 11 by the packing member 171 which is in a contracted state on the outer circumference of the pressing pin 168, and is in contact with the bottom surface of the flange portion 168a of the pressing pin 168. The steam is blocked from being discharged to the outside of the lid case 110.

As described above, after discharging the high-pressure steam inside the inner cylinder 11, the operator can open the lid means 100, so that the user is forced to open the lid means 100 in a high pressure state to cause a safety accident. It can prevent or deform the rice cooker.

As described above, the present invention is configured to allow the user to easily and simply discharge high-pressure steam manually when an abnormal high pressure occurs inside the rice cooker to prevent accidents and prevent deformation of the rice cooker. Has an advantage.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by equivalents of the utility model registration scope as well as the utility model registration scope described below.
