Description

Portable pressure cooker

The present invention relates to a portable pressure cooker capable of cooking food using its own heat source.

Recently, as leisure activities such as mountaineering and fishing have been actively carried out, cooking activities in the open air are frequently carried out, and at the same time, cooking outdoors outside of a licensed area is strictly prohibited in terms of fire prevention or nature protection.

According to this trend, instant foods developed to be eaten by heating food by pouring hot water have already been widely distributed.

However, these instant foods are cumbersome to have a separate heating device to heat water.

In addition, it is difficult to handle hot water, and there is a risk of safety accidents such as burns, and convenience foods are composed of freeze-dried ingredients, so taste and nutrition are greatly degraded.

To solve this problem, there is known a combat food heating pack that can be eaten by heating food with its own heat source without being supplied with a heat source from the outside.

The battle food heating pack is filled with a heating agent to heat the main pack with an inlet formed at one end so as to be filled with water, the food pack injected into the main pack, and the water contained in the main pack. And a steam discharge hole formed on one side of the main pack to discharge steam generated when water is heated by the heat generating pouch.

Accordingly, when water is poured into the main pack, the food pack is heated while the water and the heating agent of the heating pouch react and generate heat, and the vapors inside the main pack generated during the heating process are discharged to the outside through the steam discharge holes.

However, is it recognized that the above combat food heating pack is effective in that it can be easily heated and consumed through self-heating without providing an external heat source? It is not possible to cook unprocessed ingredients because it simply heats the food.

Therefore, the combat food heating pack can be applied only to freeze-dried food ingredients, so despite the advantage that it is easy to use, it is still not widely distributed due to its great deterioration in taste and nutrition.

However, in consideration of the convenience of operation, it is desirable to be configured to lock and release in a one-touch method.

Meanwhile, a first pressure control valve 130 is installed on the outer container lid 120. The first pressure control valve 130 is automatically opened when the pressure inside the outer container 110 rises above a certain value to maintain a constant pressure inside the outer container 110, and is used in a pressure cooker. Since it is the same as that of a conventional pressure control valve, a detailed description will be omitted.

In addition, it is preferable that the outer container lid 120 further includes a first safety valve 135 in case the first pressure control valve 130 does not operate normally. The first safety valve 135 is also similar to a conventional safety valve used in a pressure cooker, so a detailed description thereof will be omitted.

The outer container 110 has a bottom 111 and a space 114 formed along the inside of the side wall 112. In addition, a water injection port 115 is formed in the side wall 112 of the outer container 110 to supply water to the space 114. A water inlet stopper 116 for sealing the water inlet 115 is coupled to the water inlet 115.

In this case, it is preferable that the water inlet stopper 116 is firmly fastened to the water inlet 115 through a spiral coupling method so that it is not easily separated from the water inlet 115 even if the pressure inside the space portion 114 increases. Do. In addition, the water inlet 115 and the water inlet stopper 116 are preferably made of nylon resin having excellent heat resistance.

A heating material 140 is inserted into the space portion 114. The heating material 140 is a mixture of calcium carbonate and alumina powder, and generates steam heat when it comes into contact with water flowing into the space 114 through the water inlet 115.

It is preferable that the heating material 140 is positioned on the bottom 111 side of the outer container 110 so that it can be easily contacted with water.

In this case, a heating material entrance 117 communicating with the space portion 114 is formed at the bottom of the outer container 110. In addition, an entrance stopper 118 is coupled to the heating material entrance 117. The entrance stopper 118 is preferably closely coupled through a spiral fastening so as not to be easily separated from the heating material entrance 117 even if the pressure inside the space portion 114 is increased.

In addition, the heating material 140 is preferably contained in a non-woven fabric to facilitate insertion and discharge into the space portion 114 through the heating material entrance 117.

A second pressure control valve 150 is installed on the side wall 112 of the outer container 110. The second pressure control valve 150 has the same or similar configuration as the first pressure control valve 130, and the pressure of the space 114 that rises when the heating material 140 contacts water to generate steam heat is Adjust it so that it does not rise above a certain level.

In this case, it is preferable that a second safety valve 155 is provided on the side wall 112 of the outer container 110 in case the second pressure control valve 150 does not operate normally. The second safety valve 155 has the same or similar configuration when compared to the first safety valve 135.

According to the present invention, an inner container 160 containing food ingredients is seated inside the outer container 110. Like the outer container 110, the inner container 160 has a bottom and sidewalls and an open top, and is preferably made of a stainless material.

An inner container lid 170 for sealing the inner container 160 is coupled to an upper portion of the inner container 160. The inner container lid 170 is provided with a steam discharge member 180 for discharging the steam formed in the inner container 160 to the outside.

In this case, the steam discharge member 180 is composed of an elastic body 181 inserted through the inner container lid 170 and a steam discharge hole 182 penetrating the elastic body 181, which is normally sealed. While maintaining the state, when steam is generated inside the inner container 160, the steam discharge hole 182 is opened by the rising pressure of the inner container 160, thereby discharging the steam formed inside the inner container 160 to the outside. .

The vapor discharging member 180 is preferably made of a silicone material that is harmless to the human body and has excellent heat resistance, sealing power, and elasticity.

Meanwhile, the inner container 160 may be provided in plural and stacked vertically inside the outer container 110.

In this case, horizontal grooves 161 with open both ends are formed on the bottom of the inner container 160, and protrusions 171 corresponding to the horizontal grooves 161 are formed in the inner container lid 170. In addition, the vapor discharge member 180 is formed at the side end 172 of the protrusion 171 facing the open end of the horizontal groove 161.

Therefore, even if the inner containers 160 are stacked up and down, the steam inside the inner container 160 located at the bottom is smoothly discharged to the outside through the steam discharge member 180 formed at the side end 172 of the protrusion 171. You will be able to.

Using the portable pressure cooker 100 of the present invention configured as described above makes it possible to cook using its own heat source and cook unprocessed ingredients.

First, the outer container lid 120 is opened, the inner containers 160 containing food ingredients are sequentially seated in the outer container 110, and then the outer container lid 120 is closed.

For example, the lower inner container 160 contains food materials and an appropriate amount of water to be used for soup or stew, and the upper inner container 160 contains rice and an appropriate amount of water.

Then, put the heating material 140 in the heating material entrance 117, and seal the heating material entrance 117 with the entrance stopper 118, and then put an appropriate amount of water into the water injection hole 115 and insert the water injection hole 115 into the water injection hole. It is sealed with a stopper (116).

The heating material 140 in contact with water generates steam heat, and the temperature of the inner container 160 rises by the steam heat.

At this time, since the heating material 140 is isolated from the inside of the outer container 110 through the space portion 114, contact with the inner container 160 is fundamentally blocked. Therefore, there is no fear that the heating material 140 will be mixed with the food materials contained in the inner container 160.

As time elapses, the food materials contained in the inner container 160 boil, and the pressure of the inner container 160 increases due to the vapor pressure generated in this process, and the pressure of the inner container 160 rises above a certain value. When the steam discharge member 180 is opened, the steam inside the inner container 160 is automatically discharged to the outside.

In this way, since the steam is continuously discharged to the outside through the steam discharge member 180 and the outer container 110 is closed by the outer container lid 120, the internal pressure of the outer container 110 increases, Ingredients such as soup or stew in the inner container 160 are cooked by the internal pressure of the outer container 110, and the rice is steamed and turned into rice.

At this time, when the pressure of the outer container 110 rises above a certain value, the first pressure control valve 130 installed on the outer container lid 120 is automatically opened to keep the pressure inside the outer container 110 constant. And, when the pressure of the space part 114 rises above a certain value, the second pressure control valve 150 installed on the side wall 112 of the outer container 110 is automatically opened and the internal pressure of the space part 114 Since this is kept constant, safe use is guaranteed.

After a certain period of time has elapsed, the first pressure control valve 130 and the second pressure control valve 150 are forcibly opened to completely remove the internal pressure of the external container 110 and the internal pressure of the space 114 that have risen. The outer container lid 120 is opened and the inner containers 160 are withdrawn. At this time, the withdrawn inner vessels 160 are in a state in which the inner pressure of the outer vessel 110 is naturally removed while the inner pressure of the outer vessel 110 is removed.

In this way, the present invention can be easily heated and consumed through self-heating without providing an external heat source, as well as unprocessed food materials can be cooked using the internal pressure of the rising external container 110. You will be able to cook food such as rice as well as steamed crab.

As shown in Fig. 6, as another embodiment of the present invention, the present invention may further include a binding member 190 capable of binding the inner containers 160 stacked up and down.

In this case, the binding member 190 includes a locking protrusion 191 formed on a lower outer side of the side wall 112 of the inner container 160 and a side wall 112 of the inner container 160 so as to correspond to the locking protrusion 191. ) It may be composed of a hook 192 rotatably coupled to the upper outside.

Therefore, when the hook 192 of the inner container 160 located at the bottom is rotated and hooked on the locking projection 191 located at the top, the inner container 160 located at the top and the inner container 160 located at the bottom are It becomes possible to bind easily.

Since the hook 192 is installed on the upper part of the inner container 160, even if the inner container 160 is individually seated inside the outer container 110, the hook 192 is located at the bottom of the inner container 160. Since it is not interfered with, the inner container 160 can always be stably seated inside the outer container 110.

When the inner containers 160 are bound in this way, the inner container 160 located at the bottom is pulled out along the inner container 160 located at the top. In addition to being able to very easily withdraw the located inner container 160, it is possible to prevent the risk of getting burned on the hand in the process of pulling out the heated inner container 160 after cooking.
