Description

  The present invention provides a high-temperature steam that exists inside the casing of the pan when the food is cooked and the inside of the pan is in a vacuum state immediately after cooking, and the vacuum is released to open the lid of the pan. If you try to open the lid in a state where a certain amount of time has passed after cooking is complete and the internal temperature of the pan has dropped and vacuum generation has progressed In particular, the present invention relates to a cooking chamber vacuum release device that enables the vacuum to be easily released while the lid handle is held and the lid to be easily opened.

  Currently, when cooking with a pan, maintaining a constant pressure improves the taste of the food to be cooked, and also allows for long-term storage when stored after cooking in a vacuum. .

  Therefore, recently, many studies have been conducted to maintain the constant pressure during cooking and induce the vacuum after cooking to improve the taste of the food as well as to extend the preservation.

  However, if heating is stopped after the steam pressure generated during cooking is discharged while maintaining a constant pressure, the intrusion of air into the pot housing is blocked and a vacuum is induced. In such a vacuum state, the pan lid cannot be easily opened.

  Therefore, in order to open the lid of the pan, the induction of the vacuum must be released. One of the methods is to vent the inside of the pan casing to the outside.

  In order to ventilate the inside and the outside of the pan casing in this way, in most cases, the knob exposed at the top of the valve that induces vacuum is pulled upward, or the knob is slid in one direction and pulled. As a result, the flow path of the casing of the pan is opened.

  However, if the vacuum is released to open the lid of the pan at the moment when cooking is completed, hot steam is instantaneously discharged, which may cause injury to the finger operating the knob.

  In addition, in the state where a certain amount of time has passed after cooking is completed, if the temperature of the pan casing gradually decreases and the internal vacuum generation has progressed considerably, the pan lid should be opened. Since the pressure inside the body is low and a high degree of vacuum is maintained, in order to ventilate the outside, the knob formed on the upper part of the valve that induces vacuum as described above is used, and the external air is attached to the housing. By maintaining the state of operating for a certain period of time until the pressure becomes uniform while entering, the lid of the pan can be easily opened.

  However, these knobs are separated from the handle formed on the pan lid by a certain distance, so after operating the knob for the first time, grasp the handle to open the lid, or hold the handle with one hand and The knob is operated by hand, and the operation for releasing the vacuum becomes inconvenient.

  In addition, since most of the lids of such pans have a constant weight, a momentary vacuum is induced when the lid is opened and closed with the dead weight of the pan lid, and the lid is easy Will not open.

  Therefore, since the knob for always releasing the vacuum must be operated, in most cases, the handle is released with the other hand and the vacuum is released with the other hand. The vacuum release operation is inconvenient.

  Therefore, in the present invention, in order to solve these problems, the knob exposed at the upper part of the valve body attached to the lid of the pan can be operated by a lever attached around the knob, so that the temperature is high. These levers were formed close to the side on which the pan lid handle was formed, so that the lever could be easily operated with one hand.

  In addition, it is economical by providing the lever with a simple assembly structure.

  For this purpose, a cover body formed so as to cover a valve body capable of generating vacuum simultaneously with vacuum generation or pressurization, and an operating body folded in the cover body, and operating a handle operating portion of the operating body, The exposed knob floated at the top of the valve body so that the pan channel was opened.

  In addition, the handle operation part formed on these operating bodies is formed so as to protrude to one side, so that when operating the finger operation part, high-temperature steam is not discharged directly to the finger, and in this way By making the protruding finger operation part close to the handle of the pan, it was possible to easily release the vacuum and open the lid while holding the handle with one hand.

  Therefore, when a vacuum is generated after cooking is completed, the handle operating part of the operating body is formed in a different direction from the position where the steam is discharged when the vacuum is released. There is no direct discharge to the finger, and when the operator's finger operation part protruding on one side is brought close to the handle of the lid, when the lid is to be opened, the handle of the lid can be easily grasped with one hand. It was possible to open the lid easily while releasing the vacuum.

  Further, by forming these operating bodies with a cover body for protecting the valve body, it is possible to provide various design characteristics as well as protection of the valve body.

  As shown in FIG. 1, the configuration of the present invention includes a valve body 100 capable of generating a vacuum simultaneously with vacuum generation or pressurization, and opening the pan channel 1 when steam pressure is generated inside the valve body 100. A valve body 110 formed with a knob 111 for inducing the discharge of steam and blocking the flow path 1 after cooking is completed to induce a vacuum, and the whole or a part of the valve body 100 housing the valve body 110. And a cover body 10 that is fixed so as not to float from the valve body 100, and an operating body 20 that is connected to the cover body 10 and is operated by an external force. The knob 111 exposed to the above is operated to open the flow path between the valve body 100 and the pot housing 200 to allow ventilation.

  Here, the valve body 100 discharges the vapor pressure inside the housing 200 during cooking, or blocks the outside air from entering the housing 200 in a state where the heating is stopped. A packing 320 is attached to the edge of the lid 300 to which the valve main body 100 is attached, thereby maintaining the hermeticity of the casing 200.

  Here, the cover body 10 is molded of plastic or rubber so as to cover the valve body 100, and if possible, includes a means for preventing any peeling while covering the valve body 100. It is desirable to maintain an appropriate hardness that prevents floating during operation.

  Further, as a means for preventing the cover body 10 and the valve body 100 from peeling off, in the present invention, a locking portion 11 is formed in the lower portion of the cover body 10 and is hooked on the locked portion 101 of the valve body 100 and fixed. However, the object of the present invention is not limited by such a fixing method.

  Further, the structure of the operating body 20 that is operated by an external force in the cover body 10 includes a button body 20a that moves back and forth by pressurization, and a lever body 20b that induces not only front and rear but also up and down and left and right floating by pressurization.

  In one embodiment of the present invention, as shown in FIG. 2, the back and forth button body 20a is composed of a button 23a in which the pressure pin 22a is moved in and out by the expansion and contraction of the spring 21a to float the knob 111. It is elastically supported by the spring 21a and is usually formed of a locking step portion 24a that does not come into close contact with the knob 111 and prevents it from coming back while being elastically supported by the spring 21a.

  Accordingly, when the button 23a is pressed with a finger while holding the lid handle, the knob 111 is floated while the pressure pin 22a formed at the tip of the button 23a is moved forward by the spring 21a, and the flow path 1 is opened and vacuumed. Is released.

  3 to 7 show another embodiment. Here, the lever body 20b that induces not only front and rear but also up and down and left and right floating by pressurization is folded on one side of the cover body 10 to perform a hinge operation. The cover body 10 is provided with a hinge portion 12 for attaching the lever body 20b that performs the hinge operation, the hinge surface 21b is formed on the lever body 20b for the hinge operation at the hinge portion 12, and the hinge portion is formed on the hinge surface 21b. 12 is formed, and the lever body 20b is folded to the cover body 10 by the hinge pin 23b.

  At this time, the hinge surface 21 b is exposed at the upper part of the cover body 10, and the operating part 25 b for operating the knob 111 is positioned at the lower part of the cover body 10 and is in close contact with the knob 111.

  Because of such close contact, it is desirable that the operating portion 25b protrudes forward from the hinge surface 21b, but the object of the present invention can be achieved even if it does not protrude.

  In addition, a valley portion 29b is formed between the hinge surface 21b and the operating portion 25b, thereby enabling miniaturization in a state where the lever body 20b is assembled to the cover body 10, and obtaining a dense assembly structure. it can.

  In addition, a finger operation part 24b is formed on the lever body 20b, and an operation part 25b for operating the knob 111 of the valve body 100 by a pressing operation of the finger operation part 24b is formed at the tip of the finger operation part 24b.

  A support portion 26b is formed at the lower stage of the lever body 20b, that is, the lower stage of the operating portion 25b, so that the lever body 20b is accurately operated by the finger operation portion 24b and is held horizontally to facilitate the pressing operation. The support portion 26 b meshes with the meshing portion 13 formed on the cover body 10 in a state where the support portion 26 b is folded and joined to the cover body 10.

  Therefore, the lever body 20b is normally held horizontally by the support portions 26b being supported by the meshing portions 13 of the cover body 10, and when the finger operation portion 24b is pressed in such a state, the operation portion 25b is moved forward. While moving, the knob 111 of the valve body 100 is pushed out to one side, whereby the valve body 110 formed with the knob 111 that has blocked the flow path 1 is inclined to one side, the flow path 1 is opened, and external air is put into the housing. Or hot steam is discharged.

  Therefore, the lid can be easily opened by holding the handle 310 formed on the lid 300 while pushing these finger operation portions 24b.

  Further, a through hole 14 from which the knob 111 of the valve body 110 protrudes is formed in the upper part of the cover body 10, and steam discharged to the through hole portion 102 of the valve body 100 is discharged to the outer peripheral edge of the through hole 14. An opening hole 15 is formed.

  In another embodiment of the lever body 20b that induces not only front and rear but also up and down and right and left by pressurization, as shown in FIGS. 8 to 12, a mechanism for lifting the knob to the operating portion 25b for releasing the vacuum is shown. The stop base 25c is formed, and the knob 111 is formed on the knob. When the finger operating portion 24c is pushed, the knob 111 is lifted and the vacuum is released.

  Here, the locking step portion 111a includes a region 111b that can be lifted to the upper side of the knob in a state where the locking base 25c is coupled and disposed at a fixed position when the knob discharges steam by pressure. If possible, it is desirable that the locking step 111a is in close contact with the locking base 25c with the knob 111 lowered when a vacuum is induced.

  The same effect can be achieved when such a locking base 25c is formed in a ring shape and the ring is fitted into the locking step portion 111a of the knob 111 and is fixed.

  Therefore, when the finger operation unit 24c is pressed, the valve body 110 that has closed the flow path 1 is lifted while the knob 111 is lifted, and ventilation is enabled while the flow path 1 is opened, and the vacuum is released.

  In the third embodiment of the lever body 20b that induces not only front and back but also up and down and left and right by pressurization, as shown in FIG. 13 to FIG. As an example, the hinge portion of the cover body 10 is mounted in the horizontal direction, and the lever body 20b is mounted so as to mesh with the horizontal mounting state, so that the operating portion 25d slides the knob 111 to the left and right. The same effect as above can be obtained.

  In addition, the lever body 20b that operates by being folded in the cover body 10 is provided with a return spring 27 for automatically returning to the original shape when the finger operating portions 24b, 24c, and 24d are pressed. Fixing protrusions 16 and 28 are formed on the cover body 10 and the lever body 20 in order to firmly fix the spring 27 for use.
