Description

  The present invention is applied to a valve made of a weight body having a constant weight, which is used for pressure adjustment of a cooking pan, and is particularly constant for maintaining and adjusting a constant pressure. A valve made of plastic or metal having a weight of 1 is provided with a vacuum means so that a vacuum is induced in the casing of the pan after cooking.

  Generally, when cooking a food by a heating method, if the pot to be used is sealed, the pressure inside the casing of the pot is increased, cooking is possible in a short time, and the taste is also improved.

  However, in such a case, a pressure valve for discharging steam under a certain pressure is always used to adjust the pressure inside the housing.

  Therefore, these pressure valves are built in the valve body consisting of the upper and lower bodies connected to the upper and lower surfaces of the lid of the pan, and in the interior of the valve body, blocking the through flow path for steam discharge Formed from a valve body.

  At this time, the valve body is usually built in a through-flow passage that is disposed on a through-hole drilled in the lid so that the valve body is built into the valve body to facilitate assembly to the lid and to be firmly fixed. Is assembled with a screw type so as to penetrate either the upper body or the lower body on the hollow part of the valve body.

  In the valve body assembled in this way, a valve body that rises with a constant pressure or external force is usually installed so that it can float up and down and right and left in a state where the through flow passage of the valve body is blocked by its own weight.

  In addition, for such sealing, a packing is attached to the edge of the pan lid, so that when the edge of the pan lid covers the casing of the pan, the packing attached to the edge of the lid The portion that is in close contact with the housing can be tightly adhered, thereby maintaining airtightness and sealing.

  Moreover, in order to prevent the lid from being lifted by the vapor pressure generated during cooking while maintaining such a tighter seal, a lock that presses while sliding a part of the upper surface of the edge of the lid back and forth. Means.

  However, the drawbacks of these rigid weight valves are that they can maintain a constant pressure during cooking, but cannot be sealed (vacuum induction) after cooking, while maintaining the taste of the cooked food. It is impossible to store for a certain period of time.

  That is, the inside of the casing of the pan after the completion of cooking is evacuated by steam generated during cooking, so external air instantaneously enters when the pan lid is opened. In such a case, various harmful substances contained in the outside air flow in at the same time, causing deterioration of taste, and also causing decay after a certain period of time.

  Therefore, in most cases it will be necessary to reheat from time to time to prevent them, but this will cause the water to evaporate, resulting in a different taste than expected before cooking.

  Therefore, recently, an elastic material (usually using silicon having excellent heat resistance) is used for the valve body inside the valve body made of these heavy bodies to enable vacuum.

  However, in such a case, since there is almost no weight of the elastic material, it is difficult to maintain a constant pressure in the pan casing during cooking. In order to maintain the pressure, the pressure must be maintained by adjusting the discharge rate of the steam passing through the through passage of the elastic material valve body. Therefore, pressure regulation is virtually impossible.

  In addition, the valve body made of an elastic material is easy to assemble within the valve body and prevents random detachment due to vapor pressure, as well as the valve body that can lift the valve body for vacuum induction. The internal structure needs to be changed, and a complicated structure is required to induce a vacuum while allowing the valve body of the elastic material to be ventilated. When cooking food and drinks, it becomes unsanitary due to foreign matters.

  Therefore, the present invention uses a heavy valve body and a valve body to maintain a constant pressure during cooking, and also enables vacuum after cooking is completed.

  The use of such a packing for inducing a vacuum facilitates the fixing operation while maintaining the fixing of the valve even when the pressure is generated, and at the same time prevents the deformation due to the vacuum pressure when the vacuum is generated.

  In addition, there is no foreign matter mixed in during vacuum induction, and close vacuum induction is possible in any environment.

  For this reason, in the present invention, the upper body and the lower body forming the valve body are arranged on the upper and lower through holes of the lid and connected to each other, and the through passage formed by the connection is made of plastic or metal. When the valve body built in the heavy valve body is blocked by its own weight, the packing is positioned below the valve body, and the packing is in close contact with the inner wall of the through-flow passage. When the pressure is generated, the cover plate is lifted so that the cover plate of the valve body is positioned on the upper end surface of the packing. When the cover plate is lowered, the cover plate is in close contact with the upper end surface of the packing and vacuumed. Can be induced.

  In order to fix these packings in place, a locking step portion is formed on the inner wall of the through-flow passage to form an inner insertion portion, and the packing is arranged in the inner insertion portion in a state of being caught by the locking step portion. In addition, a flange is formed on the upper end surface of the packing in close contact with the inner wall of the through passage, and the lower body is formed by the thickness of the lower body in a state where the lower body and the upper body are assembled. By seating the flange, the contact surface between the cover plate and the packing of the valve body becomes large, and excellent airtightness can be maintained.

  In addition, the upper end surface exposed in the state where the packing is fitted to the inner wall of the through passage, or the upper surface of the flange formed to extend outward from the exposed upper end surface is connected to the cover plate of the valve body. Protruding lines for inducing contact are provided, which enables excellent vacuum induction even when the smoothness of the cover plate is not maintained.

  Therefore, the pressure adjustment of the pan according to the present invention can be accurately implemented depending on the characteristics of the plastic or metal to be molded, and during vacuum induction, the packing is fitted on the upper side of the through flow passage blocked by the valve body. This prevents the packing from floating even when pressure is generated, and at the same time as fixing the packing, keeps the packing flange in contact with the upper surface of the packing flange and the upper end surface where the packing is exposed. Therefore, not only when the smoothness of the cover plate of the valve body is low, but also when foreign matter is generated, close adhesion can be induced.

FIG. 6 is a cross-sectional view showing an example of another attachment state of the valve of the present invention.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  As shown in FIG. 1, the present invention includes a valve body 10 made of a plastic or metal weight body having a constant weight, which is molded so as not to be deformed by an external force, and is embedded in the valve body. The upper body 10a and the lower body 10b that form the valve body 10 are disposed on the through hole 210 of the lid 200, and are connected to and connected to the upper and lower sides of the lid. A flow path 1 is formed.

  Therefore, the valve body 20 is built in the valve body 10, and when there is no vapor pressure, the valve body blocks the through passage 1 by its own weight, and at this time the packing 30 is located at the bottom of the valve body 20. In this state, the packing 30 forms a sleeve 31, and the sleeve 31 is closely fitted to the inner wall 12 of the lower body forming the through-flow path 1, and then the valve body 20 is fitted to the upper end surface 32 of the packing 30. The cover plate 21 is arranged.

  At this time, a shaft 22 is formed on the upper side of the valve body, and the upper portion of the shaft is exposed to the opening of the upper body constituting the valve body.

  Therefore, when a constant pressure is generated in the housing 100, the pressure is transmitted to the cover plate 21 of the valve body 20 that has blocked the through flow path 1 by its own weight, the valve body 20 is raised, and the vapor passes through the through flow path. 1 and discharged to the outside through the discharge hole 11 of the upper body 10a. When the vapor pressure is removed, the cover plate 21 immediately comes into close contact with the exposed upper end surface 32 of the packing 30 due to the weight of the valve body 20, shuts off the air that enters through the discharge hole 11, and Prevents air from entering the interior and enables vacuum induction.

  At this time, the upper end surface 32 of the packing 30 must be exposed to a certain height in a state where the sleeve 31 of the packing 30 is in close contact with and fitted to the inner wall 12 of the lower body 10b that forms the through-flow passage 1. However, in order to fix such a fixed position of exposure, as shown in FIG. 2, a locking step portion 13 is formed on the inner wall 12 of the lower body 10 b forming the through channel 1, and the locking step portion 13 A fixed position is fixed by forming the inner insertion portion 14 on the upper side so that the sleeve 31 of the packing 30 is accommodated and disposing the packing 30 in the state of being caught by the locking step portion 13. At the same time, the packing is not sucked when a strong vacuum is generated.

  In addition to fixing the packing 30 at a fixed position and preventing suction, as well as providing ease of assembly, as shown in FIG. 4, the sleeve 31 of the packing 30 forms the inner wall 12 of the lower body 10 b that forms the through flow path 1. The flange 33 is formed on the upper portion of the packing 30 on which the sleeve 31 is formed in close contact with the upper end surface 15 of the lower body 10b. The function of supporting the flange 33 of the packing 30 is given. This facilitates the operation when fitting the packing 30 to the through-flow passage 1, and when the cover plate 21 of the valve body 20 is in close contact with the packing 30, the contact surface is increased by the flange 33, and friction is caused. The increase in force makes the airtightness better.

  The present invention utilizes the fact that the upper end surface 15 of the lower body 10b on which the flange 33 is seated is formed by the thickness of the lower body 10b when the lower body 10b and the upper body 10a are assembled. This does not limit the purpose of the present invention, and various methods for flange attachment can be used.

  The exposed upper end surface 32 of the packing 30 or the flange 33 formed by extending outward from the exposed upper portion and extending outward from the exposed upper end surface 32 of the packing 30 or the exposed upper portion. By providing the upper surface with a protruding line 34 for inducing line contact with the cover plate 21 of the valve body 20, when the smoothness of the cover plate 21 is not maintained, or when foreign matter is on the upper end surface 32 of the packing 30 or the flange 33. Even when it is present on the upper surface, the foreign matter can be separated to maintain the adhesive force with the packing, thereby enabling vacuum induction and good vacuum induction under any circumstances.

  At this time, the packing 30 of the present invention has a hollow portion capable of venting in the center in a state where the sleeve 31 is formed, and this is for preventing the packing 30 from being sucked in during vacuum induction. If possible, the protrusion line 34 extends to the inside of the hollow portion so as to protrude, thereby enabling close adhesion guidance, and preventing the accumulation of foreign matters and the like, while preventing the accumulation of foreign matter and the like. Even when 21 rises and floats, vacuum induction by sealing is enabled.
