The present invention relates to an opening and closing control module of the pressure cooker lid, and more particularly, in the opening and closing operation of the cookware lid using pressure, even if the internal pressure of the cookware increases, the size of the pressure is in the pressure region to which the lid should open. When the upper and lower displacement pin of the opening and closing control function is located in a low place that must be opened accurately, minimize the amount of up and down displacement at the time, and conversely, when the lid is in the pressure region where the lid should not be opened, The position of the pressure control device for opening and closing the pressure cooker to improve the convenience of opening and closing of the user in the cooking process to prevent the accident by allowing the rapid displacement to the correct position that the lid can never open.

In general, the pressure cooker (hereinafter referred to as "pressure rice cooker") is a cooking utensil to increase the cooking efficiency at normal pressure (常壓) by increasing the pressure in the pot while heating the pot in a closed space. Since the pressure cooker maintains the inside of the inner pot at a high temperature / high pressure during cooking, when the user opens the lid when the pressure exceeds the safety pressure, the high pressure steam inside the inner pot is ejected to burn the outside. In general, pressure cookers are equipped with a lid opening prevention device that prevents the lid from opening when the pressure inside the inner pot is higher than the set pressure.

1 is a side cross-sectional view showing the top of the pressure cooker according to the prior art, Figure 2 is an exploded cross-sectional view showing a lid opening preventing device of the pressure cooker according to the prior art.

In addition, a ring-shaped rotating plate 22 is installed between the lid 6 and the inner pot lid 8 to be operated in conjunction with the opening and closing operation of the lid 6, and the rotating plate 22 rotates a predetermined angle in one direction. Only when the lid 6 is opened to operate, the rotary plate 22 is rotated a predetermined angle in the opposite direction to operate the lid 6 closes.

At this time, the guide plate 24 is formed inside the rotating plate 22 so as to be located close to the hole (8h) of the inner pot lid, both sides are formed in a rectangular shape so as to be caught by the fixing pin (14).

3a and 3b are a plan view and a cross-sectional view showing a closed state of the pressure cooker according to the prior art, Figures 4a and 4b are a plan view and a cross-sectional view showing an open state of the pressure cooker according to the prior art, Figure 5 is a conventional When the inner pot pressure of the pressure cooker according to the technology is more than the set pressure is a cross-sectional view showing a state in which the lid is closed.

Specifically, looking at the state in which the lid 6 is closed, the guide 24 is located on one side of the fixing pin 14, as shown in Figure 3a and 3b, the pressure inside the inner pot (4) When the diaphragm plate 12 is less than the set pressure, since the fixing pin 14 does not protrude into the hole 16h of the cover as the diaphragm plate 12 is intact, the lid 6 is rotated in one direction. Although it can be opened, when the pressure inside the inner pot 4 is greater than the set pressure according to the cooking inside the inner pot 4, the central portion of the diaphragm 12 is moved upwards and the fixing pin ( 14 guides the spring 18 through the hole 16h of the cover and protrudes outwards, so that the guide 24 may be inserted into the hole 16h of the cover even if the user tries to open the lid 6.

On the other hand, looking at the open state of the lid 6, as shown in Figure 4a and 4b the guide is located on the other side of the fixing pin 14, the pressure inside the inner pot 4 is less than the set pressure In this case, as the diaphragm plate 12 is positioned as it is, the fixing pin 14 does not protrude into the hole 16h of the cover, so that the rotary plate 22 is rotated in the opposite direction to close the lid 6. Can be.

However, as shown in FIG. 5, the prior art is shown in FIG. 10B as having a structure in which the moving distance and the moving speed of the fixing pin 14 operated up and down according to the internal pressure wall change during cooking are proportional to the pressure change. There is a problem.

As shown in FIG. 10B, when the pressure starts to rise in the early stage of cooking, the lid opening preventing device 10 of the pressure cooker according to the prior art has a change in the internal pressure and a height displacement of the diaphragm 12 reacting according to the pressure change. Since the proportional function relationship between the linear (Linear) proportional relationship between the fixed pressure (P), although the internal pressure of the cooker rises to the set boundary pressure <P> which should not open the lid pin 14 is interlocked with Since the displacement line <A> shown in Fig. 10B does not rise to the point <b> of the lock, that is, the point where the lock is started, it only rises to the point <a> and remains in a condition that the lid can be opened. Users are exposed to hot steam being.

In contrast to the above, when the internal pressure begins to decrease after the completion of cooking, and the pressure falls to the set boundary pressure <P> which may be opened, the fixing pin 14 falls only to the point <b> of the displacement line <a>. The lid will be in an unopened condition, causing the user inconvenience to wait until it descends to the <a> point in order to open the lid, and then causing excessive damage to the switchgear.

The present invention has been invented to solve the conventional problems as described above in the opening and closing of the lid of the cookware using the pressure, the height displacement of the up and down displacement pin to control the opening / closing of the cooking pressure change amount of the internal pressure wall and The displacement speed is controlled by a non linear proportional opening / closing control function which is displaced according to the demands of the operating conditions. It is invented to solve the conventional problems and has the following objectives.

If the internal pressure of the cookware is below the set boundary pressure, which is the boundary of opening and closing, at the beginning of cooking, the height displacement pin of the switchgear control module receives the rising resistance below the set boundary height, which is the boundary of opening and closing. When the pressure rises above the set boundary pressure, the height-displacement pin, which has stayed in the low position, is rapidly raised to the set boundary height, which is the boundary of opening and closing, by the rapid inflection action, so that the opening lever of the lid can be quickly caught. Make sure the lid never opens.

On the contrary, when the internal pressure falls after the end of cooking, the upper and lower displacement pins fall below the set boundary pressure, which is the opening boundary, by the same action as the pressure raising process, but rapidly descends by the reverse operation as described above. It provides a modular opening / closing control device for cooking and cooking equipment that can remove the cause of safety accidents by increasing the convenience of user's opening / closing operation by opening the lock condition quickly and opening it correctly when it needs to be opened. If the internal pressure becomes a dangerous condition of abnormal high pressure exceeding the control range of the opening and closing control function due to abnormal operation or failure of other devices, the high pressure release pin attached to the opening and closing control device operates to rapidly release the dangerous pressure to the outside.

Hereinafter, with reference to the accompanying Figures 10a and 10b look at a practical example of the action in the cooking process of the present invention.

In the process from the start of cooking to the end of the cookware main body lid portion of the pressure rise and fall occurs, the height displacement of the diaphragm displacement member 330 and the vertical displacement pin 370 according to the pressure change As shown in FIGS. 10A and 10B, the displacement of the diaphragm displacement member 330 within the pressure range in which the cooker lid should be opened at the beginning of cooking is maintained in the state of p1-p2-p3A at the beginning of the pressure increase, and the pressure increases. Until the pressure <P> that should not be opened by the inflection induction vertexes 314 of the housing 310 is a condition of pressing the displacement reference zero point 334 of the diaphragm displacement member 330, that is, one point <p2>. p1> and <p2> remain intact, and only <p3A> causes displacement according to the pressure change, but the rising energy is condensed inside the displacement portion 332 of the diaphragm displacement member 330 until the boundary pressure <P> is exceeded. Height rise resistance of the condition Is a concave shape, that is, when the points between p1-p2-p3A and p1-p2-p3B are connected in a straight line between <p2> and <p3A>, the concave shape remains. Within the height area <HA> to be opened, the height displacement of the displacement portion 332 becomes very small relative to the pressure change amount, so that the displaced height of the vertical displacement pin 370 is located far below the boundary height <H>, and thus must be opened. If you do so, the result is a precise opening.

After that, when the pressure increases further and the boundary pressure <P> is exceeded, a rapid inflection phenomenon is caused by a kind of straight action in which the concave shape of p1-p2-p3B rapidly changes to the convex shape of p1-p2-P3C. This causes the upper and lower displacement pins 370 fastened to the diaphragm displacement member 330 to rise rapidly, the generation of the force and the action of the force that induces such a rapid inflection phenomenon is shown in Figure 10a When the displacement from p1-p2-p3A to p1-p2-p3B within the same concave condition, only the internal pressure push-up force <F1> acts but from concave p1-p2-p3B convex p1-p2 When displaced by -p3C, when the internal pressure suddenly moves from <F1>, the pushing force, and <p3B>, one point at the end of the concave condition, to one point <p3C>, which is changed to the convex condition, Ugh Is about to bend the material consists of a rapid displacement basically regarded as the sum of the forces <F2> of its own, that is, <F1> and <F2> sum (合) acts, and the diaphragm displacement member 330 by the force of.

More specifically, the force generated at the moment when it is changed from concave to convex, that is, the displacement end point 336 is rapidly bent from one point <p3B> to one point <p3C> in the opposite direction by a kind of step action. Sudden displacement of the diaphragm displacement member 330 is achieved by a combination of two forces, which are inherently added to its natural force <F2>.

According to the sequential action as described above, the vertically displaced pin 370 that is rapidly raised is locked to the opening lever 500 so that it cannot be opened even when the lid is opened. The operating characteristic described above is a process in which the internal pressure decreases after cooking. The same mechanism works in exactly when the lid should be opened and when it should not be opened.

The above operation will be described in more detail through the displacement comparison graph shown in FIG. 10B.

As shown in FIG. 10B, the proportional function relation between the internal pressure change and the height displacement of the diaphragm displacement member 330 reacting according to the pressure change when the initial pressure rise is started is shown in the displacement line. In the case of the present invention having a linear proportional relationship but having a non-linear proportional relationship unlike the prior art, the displacement energy is initially increased and lowered as shown in the displacement line <b>. The diaphragm displacement member 330 is able to stay condensed in the displacement portion 332 inside, so that the height displacement amount is very small compared to the pressure change amount in the corresponding area, and the rapid height change occurs at the point before and after the boundary pressure that generates the inflection point. Accurately control when the lid should open or not according to the pressure change conditions at the beginning and after the end of cooking. It appears as a result.

At this time, the spring 390 fastened to the outside of the up and down displacement pin 370 in the above operation process is compressed as the up and down displacement pin 370 is raised, and then the top and bottom displacement pin 370 is compressed when descending to the open position. As much spring elastic force acts as an elastic restoring force so that the vertical displacement pin 370 can descend.

In addition, the diaphragm displacement member 330 installed in the opening / closing control module 300 when an abnormality of the cooking utensil occurs during the operation as described above and the internal pressure becomes a dangerous condition of abnormal high pressure exceeding the control range of the opening / closing control function. The high-pressure release pin 350, which was fastened to the insertion flange 335 of the, leaves the insertion flange 335 and rises sharply to the uppermost end of the upper and lower displacement pins 370. Through the second pressure discharge passage 377, which is a space between the high pressure release pin 350 and the projection, the pressure discharged through the hole is made secondary, the abnormal high pressure inside the cooking utensil is rapidly released to the outside. .

In addition, as shown in FIG. 6A, the opening / closing control module 300 is assembled and assembled by the opening / closing control module 300 itself. In the line, each element component is sequentially combined to complete the module form of one body as shown in FIG. 6B, and the primary open / close control module 300 is the main assembly at the final assembly of the cooking appliance as shown in FIG. 6C. By using only two fastening bolts 111 on the lid portion 100 allows the body to be easily mounted on the lid portion. This makes the cooker body lid makers a big difference in parts management efficiency and assembly productivity compared to the conventional technology in which each individual component is assembled into the lid of the body lid.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and it is common in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
