Description

Safety valve indicating pressure of pressure rice pot

The present invention is installed on the top of the lid of the pressure cooker relates to a pressure indicator safety valve for discharging the residual pressure inside the cooker to the outside and at the same time to discharge the high pressure steam pressure to the outside.

More specifically, the present invention relates to a pressure cooker of a pressure cooker that has an improved display structure of a safety valve so that the display of the pressure is excellent, manufacturing cost is low, and assembly is excellent.

In general, a signal addition, which is a kind of safety valve, is installed at the top of the lid of the pressure cooker to effectively discharge the internal vapor pressure generated during steaming of the rice.

When the pressure inside the cooker becomes excessively high while steaming the rice, the signal weight swings from side to side to discharge the steam pressure to prevent the pressure rise inside the cooker, and the user can monitor the steaming state of the food through the sound of steam discharge and alarm. Inform.

In addition, as a separate safety device, a pressure display rod is installed at the top of the lid to display the pressure inside the cooker to the outside.

However, since the pressure cooker as described above is provided with a pressure indicator rod and a signal valve, which is a safety valve separately, the outer shape of the lid is coarse to harm the aesthetics, and foreign substances are easily caught, so that the hygiene is poor.

In addition, the pressure indicator rod and the signal weight had to be manufactured and installed separately, which caused the cost increase.

As a prior art for solving such a problem, there is a 'safety valve as a pressure display function for a pressure cooker' of Utility Model Registration No. 0135324 published in Korean Utility Model Publication.

The Utility Model Registration No. 0135324 was filed on December 20, 1995 (Application No. 95-44470) and published on July 24, 1997 (Publication No. 97-26880), October 31, 1998. It is registered as a date and the contents are summarized as follows.

That is, as described in the claims, "The display function for displaying the pressure state in the container to the outside on the lid provided with a coupling device to prevent the internal vapor pressure of the inside of the rice cooker body to be combined with each other, and high pressure steam A safety valve serving as a pressure display function of a pressure cooker having a pressure discharge function for safely discharging, the safety valve is coupled to the upper fixing nut and the lower fixing nut coupled to the lid of the pressure cooker on the side to function as a piston by the pressure action A piston surface is formed, and a part of the piston surface has a pressure display rod with a pressure discharge hole installed therein, and a valve rod which is installed inside the pressure display rod and is operated up and down integrally with a valve plate and has an elastic spring fitted thereon. At the same time the upper side of the valve rod is operated left and right while the valve plate functions as a valve operation A safety valve "also serves as the pressure display function, characterized by a safety valve is made of an optionally head for discharging the power provided.

This devise is that when there is no internal pressure of the pressure cooker, the pressure indicator rod and the valve plate of the safety valve are in close contact with each other, and when the pressure inside the cooker gradually increases, the pressure indicator rod rises first to indicate the current pressure state to the external user. When the pressure rises further, the valve plate of the safety valve is pushed upwards to compress and push up the inner elastic spring, and when fully raised, the upper head is tilted about the hinge pin by its own weight. The pressure inside the rice cooker is discharged in a continuous manner.

In addition, the head can be tilted arbitrarily by the user to discharge the residual pressure at any time.

However, such a pressure cooker has a problem in that the pressure display rod and the valve plate are complicated to manufacture, and the manufacturing cost is high, and the operation of the pressure display rod and the valve plate is undesirably deteriorated, and the durability of the pressure cooker decreases.

The present invention has been devised to solve these problems, and the technical problem is to improve the structure of the safety valve functioning as the pressure display function, so that not only the display effect of the pressure is excellent, but also the manufacturing cost is low, and the assembly and durability are excellent. will be.

In order to achieve the above object, the present invention screw-couples the valve holder and the lock nut, each of which has a pressure discharge hole and a pressure hole formed in the upper and lower ends of the lid of the pressure cooker, and the locking jaw and the lock nut in the lower portion of the valve holder and the lock nut. A hollow guide is installed between the packing and the guide, and a guide hole and a guide formed in the upper periphery of the valve shaft are inserted into the guide shaft with a compression spring. And by connecting the valve knob seated on the valve holder with a valve pin.

The present invention configured as described above, when there is no pressure in the pressure cooker, both the guide and the valve shaft are lowered by the elastic force of the compression spring and the self-weight of the valve shaft. As the low pressure acts on the valve shaft and primarily raises the valve shaft, the upper display portion (red) of the valve shaft protrudes above the valve holder, thereby visually informing the user whether there is a low pressure.

In addition, when the pressure further rises, this pressure flows into the pressure hole (gap) between the lock nut and the guide, thereby slightly increasing the guide blocked by the packing, thereby releasing pressure through the pressure discharge hole of the valve holder.

Subsequently, if the pressure inside the cooker becomes excessive, this pressure acts on the guide between the locknut and the valve shaft to raise the guide, and as the guide rises, the valve knob connected to the valve pin is raised to raise the valve holder. When the valve knob is completely spaced apart, the valve knob rotates to the center and lie on the side so that the pressure in the cooker is completely discharged secondarily through the pressure through hole and the pressure discharge hole.

During the operation, when the guide is raised, the compression spring is compressed and then serves to lower the guide while returning to its original position when the pressure is released.

In addition, the valve knob can be tilted or laid down by the user at any time to discharge the residual pressure inside the cooker at any time.

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

As shown in the present invention is installed on the lid 10 of the pressure cooker to discharge the pressure in the rice cooker and to configure a safety valve that also functions to display whether the remaining pressure,

A lock nut 20 having a pressure through-hole 21 formed on a bottom surface of the hole 11 of the lid 10 is installed, and a bottom portion thereof is fitted into the pressure through-hole 21 from an upper side thereof, respectively, at the upper and lower ends of the locking jaw 31. Inserting a hollow guide 30 in which the compression spring 40 and the packing 50 are installed, and accommodates the guide 30 and the compression spring 40 on the top of the lid 10, A valve holder 60 having a 61 formed therein is screwed with the lock nut 20, and a valve shaft 70 having a packing 80 fitted on the upper end of the protrusion 71 from the bottom of the guide 30. Inserted by connecting the valve hole 90 installed on the upper end of the guide hole 72 and the valve holder 60 of the upper circumference with the valve pin 100.

The lock nut 20 is formed in a two-stage structure in which the pressure through hole 21 penetrates the bottom center and the screw part.

The hollow guide 30 has a packing 50 fitted to the lower end of the locking jaw 31 to block a gap (pressure through hole 21) between the lock nut 20 and the guide 30, and the compression spring 40 Is coalesced between the locking jaw 31 and the valve holder 60, and a hole 32 for inserting the valve pin 100 is formed at the periphery of the guide projecting upward of the valve holder.

The valve holder 60 is connected to the lock nut 20 by passing through the hole 11 of the lid 10 at the lower end thereof, and pressure discharge holes 61 are formed at both sides thereof, and the packing ( 110) is coalesced.

The valve shaft 70 is provided with a packing 80 at an upper end of the protrusion 71, and a guide hole 72 penetrates in a longitudinal direction at an upper circumference thereof to insert the valve pin 100 therein.

The valve knob 90 is seated on the upper end of the valve holder 60, and both sides are formed with a space 91 for visually confirming the valve shaft 70 from the outside.

The valve pin 100 is inserted into the guide hole 72 of the valve shaft 70 by passing through the hole 32 of the valve knob 90 and the guide 30.

Referring to the operation and operation of the present invention configured as described above are as follows.

First, when there is no internal pressure of the pressure cooker, the guide 30 and the valve shaft 70 are both lowered by the elastic force and the weight of the compression spring 40 as shown in FIG. The pressure hole 21 is sealed by the packing 50, and the protrusion 71 of the valve shaft 70 is located inside the cooker, and the valve pin 100 is located above the guide hole 72. do.

In such a state, when the pressure inside the cooker gradually increases and a micro pressure occurs, the micro pressure primarily acts on the valve shaft 70 to rise as shown in FIG. 3.

The valve shaft is elevated while being guided by the guide 30, and rotation is prevented by the valve pin 100 fitted into the guide hole 72.

When the valve shaft 70 is raised, the upper display portion (red) is exposed to the outside through the space portion 91 of the valve knob 90 so that the user can visually check whether there is a slight pressure in the rice cooker. .

In addition, when the pressure further rises, this pressure acts on the pressure hole 21 between the lock nut and the guide to open the pressure hole 21 blocked by the packing 50, so that the guide 30 rises as shown in FIG. And, as the guide rises, the pressure in the rice cooker is discharged to the outside through the pressure through hole 21 and the lock nut 20, the inside of the valve holder 60 and the pressure discharge hole 61.

At this time, the compression spring 40 is compressed.

Subsequently, when excessive pressure is applied, the valve 30, which is seated on the valve holder 60, is raised since the guide 30 rises and the valve pin 100 fitted into the hole 32 at the top thereof also rises. When the valve knob is raised and spaced apart from the valve holder, and the valve knob is completely spaced from the valve holder, the valve knob rotates to the center and lie on the side so that the pressure in the cooker is completely discharged through the pressure through hole and the pressure discharge hole.

During the operation, the compression spring, which had been compressed simultaneously with the rise of the guide, returns to its original position by lowering the guide by the release of pressure and its own restoring force.

In addition, the valve knob can be tilted or laid down by the user at any time to discharge the residual pressure inside the cooker at any time.

As described above, the present invention fixes the valve holder and the lock nut, each of which has a pressure discharge hole and a pressure through hole formed on the upper and lower ends of the lid of the pressure cooker, and is packed between the locking jaw and the lock nut at the bottom of the valve holder and the lock nut. The carbonized hollow guide is installed, and the guide shaft and the guide hole and the valve holder formed at the upper circumference of the valve shaft are inserted into the guide shaft with a compression spring. This is done by connecting the valve knob seated on the valve pin.

In this way, when the pressure inside the pressure cooker has no pressure, both the guide and valve shafts are lowered by the elastic force and the self-weight of the compression spring. Secondly, the valve shaft is raised to inform the user of the presence of a low pressure. Secondarily, when the pressure is excessively increased, the guide rises to discharge the pressure through the pressure discharge hole and simultaneously lay the valve knob.

Therefore, the present invention is excellent in the effect of the display of the pressure through the improvement of the safety valve, the structure is simple, can reduce the manufacturing cost, and the effect is excellent assembly.
