Description

[Detailed Description of the Invention] Some pressure cookers are of a type in which the lid is mounted by rotating it by a predetermined angle with respect to the pot body using a handle.

In this type, a rubber gasket is inserted between the pot body and the lid to increase the airtightness inside the pot. Release the pressure steam inside the pot and lower the pressure inside the pot before opening the lid.

However, in this case, pressurized steam sometimes spouted out from the opposing space between the handles, which were stacked one above the other, and reached the rear of the handles, that is, the hand holding the handles, which was extremely dangerous.

This invention was devised to eliminate this drawback.
The upper surface of the handle of the pot body 3 and the lower surface of the handle a of the lid 1 are provided with arc-shaped blocking walls 13 and 14 so as to face each other in the width direction, and the opposing blocking walls completely prevent high-pressure steam from flowing out. It is designed so that it can be blocked.

Embodiments of the present invention will be described based on the drawings.

A rubber ring-shaped gasket 2 is fitted on the inner periphery of the mouth of the lid 1, and when the lid 1 is placed over the pot body 3, when the gasket 2 maintains a normal ring shape, the inside of the pot can be closed. Keep airtight.

On the other hand, in order to lower the pressure inside the pot after cooking, push a part of the gasket 2 inward to curve the part.

A decompression device is provided in the handle of the lid 1 to do this.

This mechanism and operation will be explained next.

A cavity 4 is provided in the upper handle a attached to the lid 1, and within the cavity 4, two rack rod-shaped actuators 5 and 6 are arranged in parallel at different heights, and between the two tooth rows. A pinion 7 is interposed in mesh with the pinion 7.

The upper end of the shaft of the pinion 7 is made to protrude above the handle a, and an operating lever 8 is provided on the protrusion.

A coiled spring 9 is interposed between the rear end (right end in the figure) of the actuator 6 on the lower side and the inner depth of the cavity 4.

The handle a is attached to the peripheral wall of the lid 1 at the part where it touches the root.
Two holes 10 and 11 (Figs. 2.6 and 7.8) are provided, and the tip of the actuator 5 is placed in the hole 10, and the tip of the actuator 6 is placed in the hole 11.
Allow each to advance and retreat.

From the mouth end edge of the pot body 3, outer flange-shaped protrusions 3a are provided outward at arbitrary intervals as shown in FIG.

This is an example of a pressure reducing device, and the operation method thereof will be explained next.

When cooking, the handle a attached to the lid 1 and the handle rest attached to the pot body 3 are used in a vertically overlapping state, as shown in FIG.

In this case, the gasket 2 has a normal ring shape as shown in FIG. 6, and a complete backing action is performed, so that the inside of the pot is kept airtight.

After boiling, to reduce the pressure inside the pot, turn the control lever 8 in the direction of the arrow from the state shown in FIG.

Then, the pinion 7 rotates clockwise in FIG. 6, one of the actuators 5 moves forward, and the other actuator 6 moves backward against the elasticity of the spring 9.

The forward end of the actuator 5 protrudes inwardly from the hole 10 in the peripheral wall of the lid 1, as shown in FIG. 8, and pushes a portion of the gasket 2, causing it to curve inwardly.

Therefore, as shown in FIG. 7, a gap is created between the gasket 2, the lid 1, and the pot body 3, through which the pressure steam inside the pot escapes to the outside, and the pressure inside the pot can be reduced.

Next, the lid 1 can be opened by holding the handle a and turning the lid 1 relative to the pot body 3 to the point shown in FIG.

That is, when the operating lever 8 is turned as described above, the actuator 6
moves backward against the elasticity of the spring 9, so the engagement between the tip of the actuator 6 and the terminal end 3a' of the protruding piece 3a of the pot body 3 is released, making it possible to turn the lid 1.

Note that once the lid 1 starts to be turned, the operating lever 8 may be released.

However, when the operating lever 8 is turned as described above, the pressure inside the pot can be reduced, but the pressure steam spouted out of the pot can be removed from the gap 12 (second and third) between the handles a and 1).
Scattered in all directions from the left and right of the handle, below and between them,
A part of it reaches the rear from between the handles a and l),
There is a risk of injury to the hand holding the handle.

Therefore, in the present invention, arc-shaped blocking walls are provided close to each other so as to face each other in the width direction on the lower surface of the upper handle a and the upper surface of the lower handle. It is designed so that it can be blocked.

In the embodiment, an arc-shaped blocking wall 13 is formed to protrude from the top surface of the handle of the pot body 3 in the width direction, and on the other hand, the handle a of the lid 1 has an arcuate blocking wall 13 formed inside the blocking wall 13. A case is shown in which arc-shaped blocking walls 14 are provided so close to each other that they touch each other.

That is, as shown in detail in FIG. 4, an arc-shaped blocking wall 13 is protruded from the upper surface of the handle, and an engaging stepped portion 13a for a stopper is provided at the end thereof, while the lid 1 side An arc-shaped blocking wall 14 is provided on the lower surface of the handle a so as to be close to the inside of the blocking wall 13 so as to be in contact with the blocking wall 13, and a notch 14a for engagement is provided at the starting end of the blocking wall 14.

In this way, when the handle a and the handle table are placed one above the other, the arc-shaped blocking walls 13 and 14 exist in parallel so as to almost touch each other in the gap between the two handles a and the handle a. The pressure steam that is about to flow backwards between the two is completely blocked by both the blocking walls 13 and 14,
It is safe because it does not reach the rear.

Contrary to the case of the embodiment, a blocking wall 1 is provided on the lower surface of the upper handle a.
3 may be formed in a protruding manner, and a blocking wall 14 may be provided on the upper surface of the lower handle. Alternatively, the blocking wall 13 may be formed in a protruding form on one of the handles a and l), and the blocking wall 13 may be formed on the other handle. An arcuate groove into which the blocking wall 13 is fitted may be provided, and pressurized steam may be blocked by the uneven fitting of the two.

In addition, even if one of the handles a and l) is provided with an arcuate blocking wall 13 projecting from the handle, and the other handle is simply a flat surface, the single blocking wall 13 will block the pressure steam to some extent. However, as shown in the embodiment, if a retaining step 13a is provided at the end of the blocking wall 13 and a notch 14a is provided at the starting end of the blocking wall 14, it will be easier to hold the handle 1. When the lid 1 is rotated clockwise from the state shown in FIG. 5 with respect to the pot body 3 and the handles a and b are overlapped, the engaging stepped portion 13 a and the cutout portion 14 a are aligned as shown in FIG. 4. The handles a and l) can be easily positioned by engaging as shown in FIG.

Next, the operation of the pressure reducing device when the lid 1 is closed will be explained.

When you hold the handle a of the lid 1 and turn the lid 1 against the pot body 3 (that is, turn the lid 1 clockwise from the state shown in FIG. Starting end 3a″ of piece 3a
When the handles a and b are vertically overlapped, the actuator 6 separates from the outer periphery of the protruding piece 3a and is released from the pressure.

Then, the actuator 6 moves forward rapidly due to the elasticity of the spring 9.
It engages with the stepped portion of the terminal end 3a' of the protruding piece 3a.

Due to this forward movement, the actuator 5 rapidly retreats via the pinion 7, and the seal 2, which had been pushed by the actuator 5 until then,
Due to its own elasticity, it returns to its normal ring shape (Fig. 6) and performs a complete backing action, making it possible to keep the inside of the pot airtight.

According to the present invention, when removing the residual pressure inside the pot, it is possible to completely prevent high-pressure steam from reaching the rear between the handle a and the handle, which are stacked one above the other.
It is characterized by being extremely safe as there is no danger of getting your hands on the pressure steam.
