Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vapor venting apparatus for a pressure vessel which raises the internal pressure of the main vessel and heats it at high pressure and high temperature.

[0002]

2. Description of the Related Art Conventionally, there is a pressure cooker or an electric pressure cooker in which the pressure inside the container is increased to raise the boiling point to shorten the cooking time such as cooking or simmering, but it is difficult to use. In addition, it is time-consuming and often dangerous because it is often not used. The heating mode of these pressure cookers and electric pressure cookers is a rising mode until the pressure adjusting valve such as a weight operates, a heating mode to maintain a constant internal pressure, and a steaming mode that stops heating and waits for the internal pressure to drop. It consists of modes. Since the time of this steaming mode varies depending on the type and amount of food to be cooked, there is a risk of opening the lid with internal pressure applied.Be sure to lift the weight, which is a pressure control valve, to open the lid safely. , I was instructed to remove the steam from the inside before opening the lid. Therefore, the structure of the weight is made up of the metal part of the main body and the resin part of the knob part, and the weight is tilted by holding the knob part to remove the steam.

[0003]

However, in such a structure, if the weight is tilted too much while holding the knob portion, the weight will come off, and at the same time, the internal pressure will drop at once, so that the food inside Was blown out and there was a high risk of the operator being burned.

In addition, even if the operation of the weight is completed with chitin,
There was a problem that the direction in which the steam discharged from the weight was ejected was uncertain and it was dangerous to hit the hand.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a pressure heating container which is stable in its direction so that steam can escape without the risk of burns and has excellent safety.

[0006]

In order to solve the above-mentioned problems, a steam removing device for a pressure vessel according to the present invention comprises a pressure heating vessel having a vessel for containing an object to be heated and a vessel lid for sealing the vessel, and A recess provided in the container lid, a steam nozzle provided in this recess for ejecting the steam inside the pressure heating container to the outside, a weight mounted on this steam nozzle for controlling the internal pressure of the pressure heating container, and a central portion. And a steam vent lever that is fitted in the steam nozzle with a gap to incline the weight in a certain direction. When the steam vent lever is operated, the weight is inclined. Is provided with a fulcrum portion of the vapor release lever.

[0007]

According to the present invention, due to the above-described structure, steam is discharged without touching the heated weight. The steam is ejected in a direction opposite to the steam release lever, that is, in a direction opposite to the operator of the steam release lever and stably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a cross-sectional view of a pressure heating container provided with the vapor venting device of the present invention when mounted on a high frequency heating device. In the figure, a heating chamber 2 is provided inside a high-frequency heating device 1. A rotary mounting table 4 on which the pressure heating container 3 is mounted is provided on the bottom surface of the heating chamber 2, and the rotary mounting table 4 is rotated by a periodic drive motor 5 provided in the lower portion. Reference numeral 6 is a magnetron of a high frequency generator, which supplies a high frequency into the heating chamber 2 through the waveguide 7.

FIG. 2A is a cross-sectional view of the essential parts of a pressure vessel vapor venting device according to an embodiment of the present invention. See also FIG.
(B) is a plan view of the vapor vent lever of the same apparatus. 1 and 2, (a) and (b), the pressure heating container 3
Is formed of a container 8 and a container lid 9, both of which are made of a dielectric material such as resin or ceramic that transmits high frequencies. A steam nozzle 10 for pressure adjustment is provided at the center of the container lid 9.
Is fixed, and the weight that controls the pressure on its upper part 1
1 is installed. The inner diameter of the pressure heating container 3 is kept constant by the hole diameter of the steam nozzle 10 and the weight of the weight 11. A vapor release lever 12 that lifts a weight 11 and forcibly ejects vapor is provided as a fulcrum 13 above the container lid 9.
It is mounted in a seesaw that can be moved around.

The lever 12 has a substantially rectangular shape when seen in a plan view as shown in FIG. 2B, and has a substantially elliptical shape formed by overlapping two circles at the center thereof. Holes 14 are drilled. Then, the diameter of this circle is a, the length of the line connecting the fulcrums of this circle, that is, the minimum dimension of the substantially elliptical hole 14, is b, and the mounting flange portion is the portion protruding upward from the container lid 9 of the steam nozzle 10. When the maximum dimension excluding 10A is c and the minimum dimension is d, these circles have a relation of a>c>d> b.

The central portions of the steam nozzle 10, the weight 11 and the steam release lever 12 are configured to be housed in a recess 15 provided in the center of the container lid 9. Further, 16 is a rubber packing for sealing the container 8 and the container lid 9, and 17 is a metal locking metal fitting that engages the container 8 and the container lid 9.

FIG. 3 is a top view of a vapor venting device for a pressure heating container according to an embodiment of the present invention. In the figure, container 8
And a handle 19 provided on the container lid 9
The container cover 9 and the container 8 can be assembled, sealed, and separated by grasping and sliding the container cover 9 in the radial direction and centering the container cover. Further, the handle 18 is the container 8
It is also used when carrying around. Reference numeral 20 is a safety valve made of a rubber elastic body, which operates at a predetermined pressure when pressure control becomes impossible due to clogging of the steam nozzle 10 and serves to discharge steam inside the pressure heating container 3. .. Further, lever guides 21A and 21A for restricting the vapor vent lever 12 from rotating around the vapor nozzle 10
B is provided on the top of the container lid 9.

In the above structure, when pressure control is performed using the pressure heating container 3 as described above, first, the food to be heated is put into the container 8, the container lid 9 is attached, and the radial direction is set. The container 8 and the container lid 9 are sealed by sliding to. After that, the handle 18 provided in the container 8 is held by both hands and placed in the heating chamber 2 of the high frequency heating device. At this time, since the levers 12 are mounted so that the diagonal lines of the two handles 18 provided on the left and right of the container 8 are divided into two halves at the center and are orthogonal to each other, whichever of the vapor vent levers 12 from the front side of the heating chamber 2 You will be able to operate either one. In this state, close the door of the high frequency heating device and start cooking,
The rotary mounting table 4 begins to rotate, and the internal mode of the container 8 gradually rises to a rising mode. Then, when the internal pressure reaches a predetermined pressure, excess steam is discharged from the gap between the weight 11 and the steam nozzle 10, and a heating mode in which control is performed at a constant pressure is entered. After that, the high-frequency power supply is stopped, the steaming mode in which the internal pressure is gradually decreased is entered, and the cooking ends when the internal pressure substantially matches the atmospheric pressure. At the time of this end, if the internal pressure is completely in agreement with the atmospheric pressure, there is no danger of steam being blown out even if the container 8 is taken out, but if it is taken out with the internal pressure remaining,
There is a risk that the weight 11 will tilt and vapor will blow out, resulting in burns. In addition, such a dangerous state may occur even when the user tries to take out in the middle of the steaming mode.

In such a case, that is, in the case where the steam is to be taken out at the end of cooking or in the middle of the cooking, if one end of the steam releasing lever 12 is pressed downward as shown in FIG. Lever 12 is fulcrum 1
3 tends to the front side of the operator, and at the same time, the weight 11 is lifted to tend in the same direction. Moreover, since the portion of the substantially elliptical hole 14 having the minimum dimension b slides while being guided by the minimum dimension d of the steam nozzle 10, the movement of the weight 11 is smooth and the inclination direction thereof is stable. As a result, the steam ejected from the steam nozzle 10 passes between the recess 15 of the container lid 9 and the steam release lever 12 and is ejected to the opposite side of the operator, so that there is no risk of burns. Furthermore, after that, the pressure heating container 3 can be taken out without any danger, which provides a high sense of security.

As described above, the size of the substantially elliptical hole 14 formed at the center of the vapor vent lever 12 and the vapor nozzle 1
Since the relationship between 0 and the external dimensions has a relationship such as a>c>d> b, mounting of the vapor vent lever 12
It can be easily removed, and because of the relationship of d> b, the steam vent lever 12 does not easily come off from the steam nozzle 10 unless it is displaced in the longitudinal direction of the substantially elliptical hole 14.

[0016]

EFFECTS OF THE INVENTION The vapor venting apparatus for a pressure heating container of the present invention has the following advantages.

At the end of cooking or during cooking, if the end of the steam release lever is pushed when the internal pressure of the heat container is rising, the end of the pushing side, that is, the side opposite to the pushed side, is operated. It is possible to stably eject the steam from the side opposite to the side where the person is present, and reduce the internal pressure of the heat container to the atmospheric pressure. Therefore, not only is there a risk of burns when steam is ejected, but it is safe to carry the pressure heating container after that.
