Description

[Detailed explanation of the idea] The present invention relates to a suspended double truss car.

The conventionally used kutsuka is a combination of an outer container and an inner container.The inner container is filled with food such as rice, placed inside the outer container, and the outer container is heated on a gas stove or electric heater. Alternatively, it can be heated and boiled using an electric heating device built into the bottom of the outer container.

In this configuration, since the inner container is placed on the top surface of the bottom of the outer container, the heat generated at the bottom of the outer container is transmitted from the bottom of the outer container to the bottom of the inner container, and the rice or other rice in the inner container is This had the disadvantage that the food at the bottom was heated first, which meant that the food was not cooked evenly.

In addition, with conventional rice cookers or slow cookers, when water is poured into the outer container and food is steamed in the inner container, all the hot air is released when the lid is opened midway through the steaming process to check the degree of cooking of the food. Even if the lid is replaced, the temperature of the food in the inner container will drop and then rise again, which may cause failure depending on the cooking method.

That is, an object of the present invention is to provide a double cooker that uniformly heats and cooks food evenly when cooking the food.

Another object of the present invention is to provide a double shoemaker that does not allow all of the hot air to be released even when the outer cover is opened.

According to the present invention, the invention comprises an outer container, an inner container, a ring removably provided on the periphery of the outer container, and an outer lid that is removably attached to the upper part of the ring, and the inner container is attached to the outer container. In a double cupper, the outer lid is fitted into the ring body and provided in a suspended manner, and the ring body has a first ventilation means and a second ventilation means. When worn on the body, the space formed between the outer container and the inner container communicates with the space below the outer lid through the first ventilation means, and the space between the outer container and the inner container is communicated with each other. There is provided a suspended double shoe shoe characterized in that when the pressure in the space formed in the space becomes equal to or higher than a predetermined pressure, the space is communicated with outside air through the second ventilation means.

The present invention will be explained below based on specific examples shown in the accompanying drawings.

In FIG. 1 illustrating one embodiment of the present invention, an outer container 1
A ring body 22 is airtightly and removably installed on the periphery of 0,
The inner container 20 is fitted and supported in a suspended manner on the inner edge thereof.

An outer lid 13 is removably installed on the upper part of the ring body 22 so as to cover the outer container including the inner container.

In FIG. 3 showing an enlarged view of the ring body 22, the ring body 22
is provided with a ventilation passage 23 that penetrates in the vertical direction, and includes a piston-shaped ventilation valve 36 that opens and closes the ventilation passage 23 by attaching and removing the lid 13, and a sleeve 30 that accommodates the piston-shaped ventilation valve 36.
are installed so as to cross the ventilation path 23.

In FIG. 4 for explaining the closed state of the vent valve 36, the vent valve 36 is composed of a piston-shaped valve body 37 with a narrow intermediate portion 37A, and this valve body 37 is formed by a sleeve (a part of the cylinder). ) 30 is constantly pressed outward by an elastic member 36A fixed to the back wall of the housing.

However, when the outer lid 13 is opened, the thick portion 37B of the valve body 37 completely blocks the air passage 23, and the positional relationship is such that the tip portion 37C thereof protrudes.

Therefore, in FIG. 2, which shows the condition of the bag when the outer lid 13 is opened, the air between the outer container 10 and the inner container 20 does not escape to the outside.

Furthermore, in FIG. 5 showing the open state of the vent valve 36, when the outer cover 13 is closed, the peripheral edge slope a of the outer cover 13 presses the tip protrusion 37C of the valve body 37 and moves it inward.

Therefore, the fleshy part 37A of the valve body 37 is located on the ventilation path 23, so that when the outer lid 13 is closed, the air in the outer container can circulate around the inner container 20. Become.

Note that if the outer cover 13 is removed again, the valve body 37 will be removed from the elastic body 3.
6A to the outside, and returns to the state shown in FIG. 4.

Further, the ventilation passage 23 has an air discharge passage 2, which communicates the ventilation passage 23 with the outside, in a place that is not affected by the attachment and detachment of the outer cover 13.
4 is provided, and an air release valve 40 is provided at its outlet.

In FIG. 6, which shows an enlarged view of the air release valve 40, the air release valve 40 is made up of a cylinder wall 41, a valve body 4, and an elastic member 44, and the cylinder wall 41 is provided with an opening 46.

The elastic member 44 is fixed to the inner wall of the cylinder wall 41 on the outlet side, and has a valve body 45 at the other end.

This valve body 45 completely closes off the opening 46 in a normal state, but when the pressure inside the air discharge passage 24 exceeds a predetermined level, the valve body 45 moves toward the outlet side, and as a result, the opening 46 is closed. It will be understood that via 46 the air discharge channel 24 communicates with the outside.

That is, when the pressure inside the outer container exceeds a predetermined pressure, the opening 4
6 is opened and the gas inside is released into the atmosphere.

In addition, in this aspect of the present invention, the outlet side of the cylinder wall 41 constituting the air discharge path 40 (the outlet side from the opening 46)
The inner diameter of the valve body 45 is made large so that it fits into this space 42.
It is desirable to determine the size of

As a result, under normal conditions, the valve body 45 is opened at the opening 46.
It is fixed in a position where it is blocked.

Furthermore, in FIG. 7 showing another aspect of the present invention, a ring body 22
A ventilation control valve 50 can be provided in the.

In FIG. 8, which shows an enlarged cross-section of the ventilation control valve 50, the ventilation control valve 50 has a sleeve 51. It is composed of a valve body 52, an elastic member 53, a collar and a nut 56.

Further, referring to FIG. 11, which shows an exploded view of the ventilation control valve 50, the sleeve 51 is hollow and has an opening 51 at the upper end.
1 and an air outlet 512 are formed, and this hollow part 51
3, a valve body 52 is slidably inserted therein.

The valve body 52 has an air outlet 521 formed on its upper end side surface, a protrusion 522 is airtightly arranged in the inner space 513 of the sleeve 51, and an elastic member 53 is disposed on the outer periphery of the valve body 523. A hollow portion 524 is formed in the axial direction, and a popular port 525 is provided on the side surface of the lower end of the valve body portion 523 .

The upper end of the elastic member 53 is locked to the lower part of the protruding part 522 of the valve body 52, and the lower end is held by a collar 54 disposed inside the cap nut 56, so that the valve body 52 is always kept upward. It's pressing.

Returning to FIG. 8 again, the collar 54 is slidable along the valve body 523 and is always in contact with the popular port 5 of the valve body 51.
25 is pressed by an elastic member 53 so as to close it.

Further, it is necessary that the inner diameter of the hole 561 of the cap nut 56 be larger than the outer diameter of the valve body 523 of the valve body 52 in order to fix the collar 54 at a certain position, that is, to lock it with the nut 56.

Further, the upper end portion 526 of the valve body 52 is arranged in such a position that it projects upward from the opening 511 at the upper end of the sleeve 51 .

As shown in FIG. 8, when the outer cover 13 is removed, the valve body 52 is pressed by the elastic member 53 and is in the upper position, and its upper end 526 extends upward from the upper end opening 511 of the sleeve 51 as described above. It stands out.

The lower end port 525 is closed by the collar 54, and the air inside the outer container 10 is in a sealed state.

Further, as shown in FIG. 9, when the pressure inside the outer container 10 exceeds a predetermined value, the collar 54 is moved upward, and the popular port 525 located on the lower end side of the valve body 52 is opened.

Therefore, the air in the outer container 10 is discharged to the outside through the intake port 525, the hollow portion 524, and the air outlet 521 at the upper end.

In FIG. 10 showing a state in which the outer cover 13 is attached to the annular body 22, the upper end 526 of the valve body 52 is attached to the projecting edge 13 of the outer cover 13.
1, the valve body 52 moves downward, and the outlet port 521 of the valve body 52 becomes in a positional relationship such that it faces the outlet port 512 of the sleeve 51.

At this time, the lower end of the valve body body 523 is connected to the hole 561 of the cap nut 56.
It protrudes more and the popular opening 525 is released from the obstruction of the collar 54.

Therefore, the air inside the outer container 10 is
24 and the air outlet 521, the air also reaches the lower part of the outer lid 13 from the air outlet 512 on the side surface of the upper end of the sleeve.

Incidentally, as shown in FIG. 7, the outer cover 13 is provided with an air release port 132 to release a portion of the air and prevent the pressure inside the shoe bag from increasing.

In this case, it is of course possible to provide a suitable safety valve instead of the air outlet 132.

As can be seen from the above explanation, when the lid of the present invention is put on, the hot air generated in the outer container automatically spreads around the entire inner container, and when the lid is removed, it is communicated with the interior space of the lid. The hot air is blocked, and the hot air surrounding the outer periphery and bottom of the inner container is not released to the outside, increasing the heat retention effect of the inner container, and automatically releasing the hot air to the outside when the pressure of the hot air reaches the expected pressure. It is safe and practical as it prevents excessive pressure.

Although the drawing showing the specific embodiment of the present invention does not have any heating device installed at the bottom of the outer container, it is also possible to install an electric heating device at the bottom of the outer container of the kutsuka of the present invention. Needless to say, it can be done.
