Description

Non-Return Type Steam Discharge Valve {STEAM DISCHARGE VALVE FOR PRESSURE COOKER}

The present invention relates to a steam discharge valve of the electric pressure cooker, and more specifically, the problem occurs in the heater and the electric control device of the electric pressure cooker during cooking using the electric pressure cooker, so that the steam pressure is excessive (hereinafter " Steam overpressure), when it occurs, it not only safely discharges the steam overpressure to the atmosphere but also manages the pressure section that discharges steam overpressure uniformly so that the steam pressure inside the electric pressure cooker can be evenly managed. It's about a discharge valve.

The present invention relates to a steam discharge valve of the electric pressure cooker, and looks at the prior art.

1 is a structural diagram of a conventional steam discharge valve in an inoperative state;

2 is a structural diagram of a conventional operation state steam discharge valve.

When cooking by applying power to the electric pressure cooker, the steam discharge valve of the present application does not operate when problems such as heating device, electric control device of the electric pressure cooker does not occur. However, when a problem occurs in the electric pressure cooker's heating device or electric control device, the inside of the electric pressure cooker is excessively heated, or the steam pressure inside the electric pressure cooker rises more than necessary due to a malfunction or clogging of the solenoid valve. Is generated, and the steam discharge valve is operated. However, when using a conventional steam discharge valve is as follows.

Conventional steam discharge valve configuration has a base portion 130 having a steam discharge hole 110 in the inner pot lid (C), the packing portion 121 for opening and closing the steam discharge hole 110 on the base 130 , The lifting pin 122 is connected to the packing part 121, and the lifting pin 122 includes a stopper 122b for supporting the spring 123 and an end portion of the upper part of the cover 140 and a hook 122a for supporting the lifting pin 122. ). After the configuration as described above, the cover 140 is configured to wrap the outside so as not to be separated while fixing the lifting pin 122, the spring 123, the packing portion 121, the base 130 by using a screw (S) It was configured to fasten with fastening. The steam discharge valve configured in this way was mounted on the inner pot lid (C) of the electric pressure cooker.

After the steam discharge valve 100 is mounted on the inner pot lid C as described above, and when cooking by applying power to the electric pressure cooker, if the problem does not occur in the heating device or the electric control device of the electric pressure cooker, The discharge valve 100 does not operate. However, when a problem occurs in the heating device, the electric control device of the electric pressure cooker, the inside of the electric pressure cooker (D) is excessively heated, the steam pressure rises more than necessary in the inside of the electric pressure cooker (D) to generate steam overpressure, The steam discharge valve 100 is operated. The generated steam overpressure is a load of the spring 123 supporting the packing part 121 through the steam discharge hole 110, and a friction force between the cover end portion and the hook 122a. Is pushed out and released to the atmosphere. At this time, how many kgf / ㎠ to determine the pressure of steam overpressure (kgf / ㎠) is somewhat different depending on the electric pressure cooker manufacturers, but is usually determined within 1.3 ~ 2.4kgf / ㎠. In order to control the steam overpressure determined by the electric pressure cooker, the force acting in the opposite direction to the steam overpressure, that is, the thickness of the packing portion 121, the load of the spring 123, the friction force between the cover end portion and the hook 122a, etc. Three factors must be managed. In addition, in order to maintain the non-return form after the steam discharge valve is operated, the side gap between the packing part 121 and the steam outlet hole 110 must be configured to be constant, so that when a certain steam overpressure occurs, When the steam pressure is filled in the hole 110 and the packing part 121 and the hook 122a are pushed up by the vapor pressure, the hook 122a, which is an elastic member, opens to both sides and covers the end of the cover. The pressure (kgf / ㎠) can be released. However, the above four conditions are not only very difficult to manage the rubber packing portion 121 and the elastic member spring 123 in the production process of the parts, but also to maintain the friction angle with the cover end by managing the open angle of the hook blade. To manage it, you have to accept high failure rate. In addition, the lifting pin 122 is pushed upward when the steam overpressure is discharged, and the hook 122a must be fixed to each other by covering the cover end, but pressure is not applied to the entire surface of the packing portion 121 at the same time. When applied, only one end surface of the packing part 121 may be lifted and the lifting pin 122 may not be pushed upward, and thus the hook 122a may not be fixed to the cover end.

In addition, in the case of inspecting the steam discharge valve, in the prior art, since the base 130 is mounted on the inner pot lid (C) and the steam discharge valve is mounted, the steam discharge valve is mounted on the inner pot lid (C), and then the entire electric pressure cooker is installed. There was a hassle of having to check the power supply.

In order to solve the problems of the prior art, the present invention facilitates the inspection of the steam discharge valve unit, and when the steam overpressure is generated in the electric pressure cooker, the steam overpressure can be quickly released to the atmosphere to release the steam overpressure quickly. The lifting pin is non-return type that can open the orifice continuously when the steam discharge valve operates due to steam overpressure. The purpose of the present invention is to provide a high quality steam discharge valve for an electric pressure cooker that can be managed in a constant range.

In the present invention, in order to solve the problems of the prior art, a separate base 130 is configured separately to facilitate the inspection of the steam discharge valve unit, and the separately configured base 130 is filled with pressure lifting pin (122) The pressure filling chamber 160 is configured to push the pressure toward the hook 122a, and when the lifting pin 122 is moved in the direction of the hook 122a, the steam discharge chamber 170 can be quickly released so that the steam overpressure can be released quickly. It is provided so as not to interfere with the hook wing 122e and the cover contact surface 140b on the lifting pin 122 to manage the uniform steam overpressure, the steam overpressure is generated when the hook wing (122e) at the initial discharge The cover contact surface 140b is configured to reduce the defect rate by reducing one factor that determines the pressure of the vapor overpressure discharged by not interfering with each other. In addition, when the lifting pin 122 is completely pushed in the direction of the hook 122a by configuring the lifting pin 122 and the external steam discharge hole 131 including the pressure plate 122c when discharging the steam overpressure, the hook end portion ( A) is fixed to the cover end portion (B), so that steam overpressure is generated in the electric pressure cooker (D), and when the lifting pin 122 operates in the direction of the hook 122a, the lifting pin 122 is a vapor discharge hole. It is configured to be non-returned in the (110) direction, to safely release the steam overpressure of the electric pressure cooker, and to evenly manage the pressure inside the electric pressure cooker to improve the quality improvement of the electric pressure cooker, and to use the electric pressure cooker safely. Steam outlet valves are provided.

As described above, according to the present invention, when the steam discharge valve of the present source is used for the electric pressure cooker, when the steam overpressure occurs during cooking, the steam overpressure can be safely discharged to the atmosphere, and the steam overpressure can be managed more precisely by controlling the reference pressure of the steam overpressure. The electric pressure cooker with improved quality can be provided, and the steam discharge valve can be provided to reduce the cost by drastically lowering the defective rate of steam overpressure inspection during product production.

First embodiment

As shown in Figures 3, 5 and 6

The steam discharge valve 100 for the electric pressure cooker of the present application has a smaller cross-sectional area of the side surface of the orifice 132 through the combination of the outer diameter of the pressure plate 122c and the inner diameter of the pressure filling chamber 160 so as to fill the pressure during steam overpressure discharge. The pressure filling chamber 160, the steam discharge hole 110, the orifice 132 and the orifice side surface area through the combination of the inner diameter of the steam discharge chamber 170 and the outer diameter of the pressure plate 122c for the smooth discharge of the steam overpressure (132) a base 130 composed of a vapor discharge chamber 170 configured to be larger than the cross-sectional area; Seat 121a which blocks the orifice 132 and prevents the leakage of steam from the inside of the electric pressure cooker D when not in operation; and the seat 121a are assembled and fastened, and the pressure plate 122c, the hook end A and the hook wing A lift pin 122 including a hook 122a and a lift pin spring guide 122d including an elastic body; and a cover spring guide 140a, an external steam discharge hole 131, a cover contact surface, A cover 140 including a cover end portion B; A spring 123 seated between the cover spring guide 140a and the lifting pin spring guide 122d; Consists of.

The steam discharge hole 110 of the base 130 is configured to communicate with the electric pressure cooker inner (D), and the lifting pin 122 assembled with the seat 121a is the base 121 when the seat 121a is not operated. By blocking the orifice 132 of the) is configured so that the pressure of the inner pressure cooker (D) does not leak to the outside. The spring 123 is seated on the elevating pin spring guide 122d, and the upper portion of the spring 123 is assembled by fitting the cover 140 so that the cover spring guide 140a is seated. At this time, the cover contact surface (140b) and the hook blade (122e) is configured so that there is no interference in the non-operation, the pressure plate 122c of the lifting pin 122 is configured as shown in Figure 5 to be seated in the pressure filling chamber 160. .

The steam discharge valve 100 configured as described above is mounted to the inner pot lid (C) of the electric pressure cooker by using a screw (S) such that the steam discharge hole (110) passes through the electric pressure cooker (D). When the electric pressure is applied to the electric pressure cooker after mounting in this way, cooking starts. When the cooking device does not have a problem such as a heating device or an electric control device of the electric pressure cooker, the steam discharge valve does not operate. However, if a problem occurs in the heating device, the electric control device of the electric pressure cooker, and the inside of the electric pressure cooker is excessively heated, the steam pressure rises more than necessary inside the electric pressure cooker (steam overpressure). At this time, the steam discharge valve 100 is operated, the process of discharging the generated steam overpressure to the atmosphere is as follows.

The steam overpressure generated in the inner pressure cooker D pushes the sheet 121a surface through the steam discharge hole 110 and the orifice 132 to start to discharge the steam overpressure. The higher the steam overpressure inside the electric pressure cooker (D), the stronger the force pushing up the sheet 121a, so that the amount of steam overpressure discharged becomes larger. The steam overpressure discharged by pushing the seat 121a is discharged between the inner wall of the pressure filling chamber 160 and the outer diameter of the pressure plate 122c, and the amount of steam overpressure discharged through the orifice 132 is the pressure filling chamber ( 160, when the amount greater than the amount discharged between the inner wall and the outer diameter of the pressure plate (122c) is configured to push the pressure plate (122c) in the direction of the hook (122a) at a high speed and a large force instantaneously. At this time, when the lifting pin 122 is also pushed in the direction of the hook 122a, the hook blade 122e having elasticity is opened to both sides while leaving the cover contact surface 140b. It is configured in a non-return mode that cannot be returned by being caught by the cover end A when returning to the direction. In addition, when the pressure plate 122c is momentarily subjected to steam overpressure, the resistance of the hook blade 122e and the cover contact surface 140b becomes a resistance that affects the opening pressure slightly, and thus does not affect the opening pressure range. Will not. The steam discharge valve 100 configured as described above passes through the steam discharge hole 110 when steam overpressure is generated in the inside of the electric pressure cooker D, and pushes up the seat 121a through the orifice 132 of the inside of the electric pressure cooker D. The steam overpressure is discharged to the pressure filling chamber 160. At this time, when the amount of steam overpressure discharged through the orifice 132 is greater than the amount discharged between the inner wall of the pressure filling chamber 160 and the outer diameter of the pressure plate 122c, the lifting pins including the pressure plate 122c and the hook 122a. The entirety of 122 is pushed in the direction of the hook 122a so that the pressure plate 122c is pushed to the vapor discharge chamber 170. Steam overpressure is to be discharged to the atmosphere through the steam discharge chamber 170, the external steam discharge hole 131 to release the steam overpressure in the electric pressure cooker (D). In addition, when the pressure plate 122c is pushed up to the steam discharge chamber 170, the volume of the steam discharge chamber 170 is configured to be larger than the volume of the pressure filling chamber 160, so that the steam overpressure can be quickly discharged to the atmosphere. As described above, the steam discharge valve quickly discharges the steam overpressure into the atmosphere, and the hook end portion A is caught by the cover end portion B so as to be non-returned, so that the consumer cannot use the product again. It is configured to use electric pressure cooker more safely.
