However, there is a risk that the hook or the jaw may be damaged when the upper and lower housings are opened and closed repeatedly in the vapor cover 270 .

In addition, since it was necessary to additionally form a rib in order to prevent damage to the hook or jaw, there was a problem in that the production becomes a little more complicated and the production cost increases.

In addition, while holding the lower housing with one hand, with the other hand, it was difficult to use the upper housing because it was necessary to hold the hook near the portion of the upper housing and forcibly pull it apart. In addition, since the forcibly pulled upper housing is instantly separated from the lower housing, dew condensation accumulated in the vapor cover 270 may splash in all directions, which is unsanitary.

Among the components of the present invention to be described below, for the same components as in the prior art, reference will be made to the above prior art, and a separate detailed description thereof will be omitted.

The electric pressure cooker 10 of this embodiment largely includes a lid 30 that opens and closes the main body 20 in which the inner pot is accommodated, and a hinge 50 that connects the main body 20 and the rear of the lid 30 .

A detachable inner pot is housed inside the main body 20 .

The first steam outlet 62 for the pressure weight 40 and the second steam outlet 64 for the solenoid valve are formed on the upper side of the lid 30, and the steam caps 100 and 100 are separably seated. A groove 60 is formed.

At this time, a fence-shaped open-type guard 66 is formed around the first steam outlet 62 .

A drain hole 68 is formed at the edge of the bottom 306 of the seating groove 60 facing the open side of the open guard 66 .

The steam cap 100 includes an upper housing 200 in which a through hole 202 in which the pressure weight 40 is disposed and a steam discharge hole 204 are formed, and a lower outlet 308 connected to the second steam outlet 64 . ) is configured to include a lower housing 300 that is formed.

The upper housing 200 and the lower housing 300 are slide-coupled. In more detail, at least one of the upper housing 200 and the lower housing 300 slides so that the upper housing 200 and the lower housing 300 can be coupled or separated from each other.

The steam cap 100 of this embodiment includes a protrusion 320 formed in any one of the upper housing 200 and the lower housing 300, and an insertion groove 210 formed in the other and into which the protrusion 320 is inserted. It is configured to further include a locking member including a.

The protrusion 320 has a slightly curved rectangular shape when the lower housing 300 is viewed in a plan view, as shown in FIG. 10( b ).

At this time, the insertion groove 210 has an open side so that the protrusion 320 is inserted from the side. That is, in the steam cap 100 of this embodiment, when the user holds the upper housing 200 and the lower housing 300 with one hand and turns at least one of the two, the protrusion 320 is inserted into the insertion groove 210 or the insertion groove Since the upper housing 200 and the lower housing 300 are coupled or separated while being removed from the 210, the use of the steam cap 100 is simple. In addition, unlike the conventional steam cap that is momentarily separated by applying strong force, the steam cap 200 of this embodiment separates the upper housing and the lower housing by rotating the upper housing and the lower housing. am.

The insertion groove 210 has an outer peripheral surface 212, a first stopper 214a that is a stopper protruding outward from the outer peripheral surface of the upper housing 200 or the lower housing 300, and one end is connected to the first stopper 214a. It is configured to include a support piece 220 that is formed.

Therefore, when the upper housing 200 and the lower housing 300 are combined, the protrusion 320 is supported by the support piece 220 to prevent the lower housing 300 from being separated downward.

In this embodiment, the insertion groove 210 is formed in the upper housing 200 , and the protrusion 320 is formed in the lower housing 300 . Accordingly, the first stopper 214a is formed on the upper housing 200 .

On the other hand, the upper housing 200 includes an upper plate 206 , a sidewall 208 protruding from the lower surface of the upper plate 206 while being spaced apart from the circumference of the upper plate 206 by a predetermined distance, and an insert protruding outward from the sidewall 208 . It is configured to include a groove (210).

The outer circumferential surface 212 of the insertion groove 210 is parallel to the outer circumferential surface of the upper plate 206 .

A first stopper 214a constituting the insertion groove 210 and a second stopper 214b spaced apart from each other by a predetermined distance are formed in the upper housing 200 .

That is, the stopper is configured to include a first stopper 214a and a second stopper 214b connected to the support piece 220 while being spaced apart from the first stopper 214a by a predetermined interval.

The first stopper 214a and the second stopper 214b are connected substantially perpendicularly to the sidewall 208 .

When the upper housing 200 and the lower housing 300 are coupled, the protrusion 320 is positioned closer to the first stopper 214a than the second stopper 214b.

Before the upper housing 200 and the lower housing 300 are coupled to each other or when separated after being coupled, the protrusion 320 is positioned closer to the second stopper 214b than the first stopper 214a. That is, since the first stopper 214a and the second stopper 214b help position the protrusion 320 , it is convenient to use the steam cap 100 .

If the first stopper 214a and the second stopper 214b are not present, the protrusion 320 deviates from the insertion groove 210 and it is difficult to maintain the coupling between the upper housing 200 and the lower housing 300 .

On the other hand, the insertion groove 210 is configured to further include an upper surface (216). In this case, the upper surface 216 includes a side wall 208 and a portion protruding from an outer circumferential surface of the side wall 208 . At this time, the height between the upper surface 216 and the lower surface of the upper plate 206 is lower than the height between the lower surface of the upper plate 206 and the lower end of the side wall 208 .

At this time, the support piece 220 protrudes below the lower end of the side wall 208 .

Also, the upper surface 216 is parallel to the upper surface of the support piece 220 , and the upper surface 216 and the support piece 220 are vertically connected to the first stopper 214a. That is, the insertion groove 210 has a 'C' shape surrounded by the upper surface 216 , the stopper, and the support piece 220 .

Therefore, the steam cap 100 of this embodiment has the inside and side surfaces of the insertion groove 210 open to communicate with the external space, and further includes a space formed by being surrounded by the first stopper 214a and the support piece 220 . is composed Hereinafter, the space is referred to as a first space 218a.

In addition, the steam cap 100 of this embodiment is configured to further include a second space 218b communicating with the first space 218a.

The second space 218b is a space surrounded by the second stopper 214b and the outer circumferential surface 212 and the upper surface 216 of the insertion groove 210, one side communicating with the other side of the first space 218a, and the upper This is a space in which the protrusion 320 is located when the housing 200 and the lower housing 300 are combined and then separated.

In this embodiment, there are three insertion grooves 210, and each of them is formed to be spaced apart from each other at regular intervals.

The steam cap 100 of this embodiment is formed in the insertion groove 210 and has a protrusion 216a facing the support piece 220, and a groove 322 formed in the protrusion 320 and into which the protrusion 216a is fitted. It includes more.

A fitting guide part 326 inclined upward from one end to the other side of the protrusion 320 is formed on one side of the groove 322 . Therefore, when the upper housing 200 or the lower housing 300 is rotated to be coupled to each other, the protrusion 216a rides the inclined fitting guide part 326 and is easily moved toward the groove 322 and fitted into the groove 322. .

In addition, the protrusion 216a of the insertion groove 210 is fitted into the groove 322 of the protrusion 320 so that the coupling between the upper housing 200 and the lower housing 300 is more reliably maintained.

On the other hand, the steam cap 100 of this embodiment is formed to be inclined downwardly from one end of the protrusion 320 to the other side, the downward inclined portion 324 positioned on the opposite side of the fitting guide portion 326, and the other end of the support piece 220 . It is configured to further include an upwardly inclined portion 224 formed to be inclined upward to one side.

When the upper housing 200 is viewed in a plan view as shown in FIG. 10( a ), the distance between the second stopper 214b and the other end of the support piece 220 is shorter than the distance between one end and the other end of the protrusion 320 . In addition, the cross section of the support piece 220 is formed close to a trapezoid. In addition, the other end of the support piece 220 is inclined from the outside to the inside.

Therefore, the protrusion 320 can be more easily inserted into the second space 218b, and after being inserted into the second space 218b, the downwardly inclined part 324 is the upwardly inclined part 224 of the support piece 220. Since it can be easily inserted into the first space 218a while riding, the distance between the second stopper 214b and the other end of the support piece 220 is shorter than the distance between one end of the protrusion 320 and the other end of the upper housing 200 ) and there is no problem in the coupling and separation of the lower housing 300 .

In addition, when the upper housing 200 and the lower housing 300 are coupled and separated, the protrusion 320 does not easily come out from the second space 218b, so that the coupling and separation of the upper housing 200 and the lower housing 300 are difficult. Easy. That is, since the coupling and separation are not immediately connected, and the housings are placed over each other between the two processes, it is useful when the protrusion 320 is removed from the first space 218a to be separated and then inserted again. For example, when the lower housing 300 is pulled out in parallel from the upper housing 200, the long protrusions 320 at both ends are caught by the support piece 220 and do not fall out, so give the lower housing 300 a slight inclination. should be withdrawn from the upper housing 200 at an angle.

Meanwhile, a through hole 202 and a steam discharge hole 204 are formed in the upper plate 206 of the upper housing 200 .

The through hole 202 is formed to protrude upward and downward from the upper plate 206 .

The upper protrusion 320 of the through hole 202 has a slight height, and the lower protrusion 320 protrudes lower than the lower end of the side wall 208 .

The outer diameter and inner diameter of the lower side of the through hole 202 are gradually reduced toward the bottom.

In addition, a guard 232 is formed on the upper plate 206 of the upper housing 200 near the outside.

The guard 232 is in an arc shape, and is spaced apart from the side wall 208 inward by a predetermined interval.

In this embodiment, three guards 232 are formed while being spaced apart from each other at intervals of about 120 degrees. In more detail, the guard 232 is positioned between the support piece 220 and another support piece 220 .

Between the guard 232 and the side wall 208, the guard 232 and the side wall 208 and the guard 232 and the sidewall 208 and the rib connected to the fixed portion 234, which is a protrusion formed in an arc-shaped fixing portion 234, (236) is formed.

The sidewall 208 projects more downwardly than the guard 232 , the guard 232 projects more downward than the fixing portion 234 , and the fixing portion 234 projects more downwardly than the rib 236 . has been

The rib 236 is formed in a straight line from the sidewall 208 toward the central axis of the through hole 202 .

Therefore, a space is formed between the guard 232 and the fixing part 234 , the fixing part 234 and the side wall 208 , and an outer packing 410 to be described later is fitted in this space.

On the other hand, the lower housing 300 is largely composed of an outer cylinder 302 , an inner cylinder 304 through which the pressure weight 40 passes, and a bottom 306 connecting the inner cylinder 304 and the outer cylinder 302 .

Accordingly, when the upper housing 200 and the lower housing 300 are coupled, the outer cylinder 302 of the lower housing 300 is fitted to the sidewall 208 of the upper housing 200 .

In more detail, the outer cylinder 302 has a protrusion 320 and a lower end of the protrusion 320 and is connected to the lower end of the side wall 208 of the upper housing 200 to reduce the gap between the upper housing 200 and the lower housing 300. The shielding piece 312 to cover, the lower end is connected to the upper end of the shielding piece 312, the outer peripheral surface faces the inner peripheral surface of the side wall 208, and the upper surface is parallel to the upper surface of the outer cylinder 302, and an outer packing 410 to be described later and A contact piece 314 to be closely adhered is formed.

The protrusion 320 , the shielding piece 312 , and the close contact piece 314 are all formed along the outer circumferential surface of the outer cylinder 302 .

One side of the shielding piece 312 is connected to the other side of the protrusion 320 , and the other side is spaced apart from one end of the connected protrusion 320 and the other protrusion 320 by a predetermined distance.

The outer and inner thickness of the shielding piece 312 is thicker than the outer and inner thickness of the close contact piece 314 .

The close contact piece 314 is spaced apart from the protrusion 320 by a predetermined distance at both one end and the other end.

The length of both ends of the close contact piece 314 is shorter than the length of both ends of the shielding piece 312 .

In this embodiment, since three protrusions 320 are formed, the shielding piece 312 and the close contact piece 314 are also formed three.

On the other hand, the steam cap 100 of this embodiment is located between the lower surface of the upper housing 200 and the upper surface of the lower housing 300, the outer packing 410 located inside the outer circumference of the steam cap 100. Consists of further including.

In more detail, the outer packing 410 is positioned between the side wall 208 and the guard 232 .

Therefore, when the upper housing 200 and the lower housing 300 are coupled, the outer packing 410 is in close contact with the upper surface of the lower housing 300 and the contact piece 314 .

The outer packing 410 is composed of a ring 412 and a locking piece that is formed to protrude from the inner circumferential surface of the ring 412 and fixes the outer packing 410 fitted to the upper housing 200 .

A central portion of the ring 412 is recessed, and the central portion is fitted to the fixing portion 234 of the upper housing 200 .

When the outer packing 410 is fitted to the upper housing 200, the engaging piece is positioned between the guard 232 and another guard 232 and is caught by the guards 232 on both sides.

Therefore, the locking piece is composed of a total of three because it must be positioned between each of the guards (232).

Meanwhile, in the upper housing 200 , the upper plate 206 is inclined downward from the front to the rear, so the height of the guard 232 also decreases from the front to the rear. Therefore, in the locking piece, the height of the first locking piece 431 positioned in front of the upper housing 200 is the highest, and the height of the second locking piece 432 and the third locking piece 432 positioned on both sides is each other. same.

Of course, the height of the second locking piece 432 and the third locking piece 432 decreases from the front to the rear.

Since the first locking piece 431 has a high height and can be easily bent when a load is applied, an oval having a long length at both ends is formed along the ring 412 in order to maintain its shape by itself.

In addition, the center of the first locking piece 431 penetrates up and down.

When the outer packing 410 is viewed in a plan view, the cross-sections of the second locking piece 432 and the third locking piece 432 are a 'c' shape protruding from the ring 412, and the open part of the 'c' shape is the central part. communicates with

On the other hand, as shown in FIG. 8 , a rib protruding substantially vertically from the inner circumferential surface of the side wall 208 is formed on the side wall 208 between the guard 232 and the guard 232 on which the first locking piece 431 is caught. Therefore, the position or shape of the first locking piece 431 is supported by contacting the outer surface with this rib.

On the other hand, on the upper side of the inner cylinder 304 of the lower housing 300, a flange 305 is formed that protrudes inward from the inner circumferential surface so that the through hole 202 of the upper housing 200 comes into contact with the upper surface. Therefore, a space is formed between the lower side of the through hole 202 and the flange 305 and the inner cylinder 304, and the inner packing 420 is located in this space.

That is, the steam cap 100 of this embodiment is configured to further include an inner packing 420 positioned between the through hole 202 of the upper housing 200 and the lower housing 300 .

In addition, the inside of the inner cylinder 304 surrounds the outer wall of the open-type guard 66, the upper end of which is hung and seated on the upper end of the open-type guard (66).

On the other hand, the bottom 306 is inclined so that the depth increases from the front to the rear.

The bottom 306 has a drain hole 316 connected to the inner peripheral surface of the outer tube 302 and the rear of the inner tube 304 is formed, and a drain hole 318 is formed at the outer edge of the drain hole 316 .

The drain hole 316 protrudes to the lower side of the lower housing 300 and is recessed.

Further, the bottom 306 is formed with a lower outlet 308 connected to the second steam outlet 64 .

The lower outlet 308 has a hole 308a formed in the bottom 306, a disk 308b disposed above the hole 308a, and a plurality of connecting bands connecting the hole 308a and the disk 308b ( 308c).

In particular, the bottom surface of the disk 308b has a funnel shape as shown in FIG. 8 , and serves to disperse the resistance of the steam ejected from the second steam outlet 64 . Accordingly, the steam coming out of the second steam outlet 64 collides with the disk 308b and escapes into the space between the connecting strips 308c.

As described above, in the steam cap 100 of this embodiment, most of the steam discharged from the first steam outlet 62 and the second steam outlet 64 is collected in the steam cap 100 and the lower housing 300 is drained. It has a structure for draining through the hole 318 and the drain hole 68 of the lid 30 .

A part of steam is discharged to the outside of the lid 30 by the steam discharge hole 204 so that a large pressure is not applied to the inside of the steam cap 100 .

Meanwhile, a plurality of drain passages 238 are formed on the upper surface of the upper housing 200 along concentric circles. That is, the drain passage 238 is formed in the form of a circle and a groove between the circles.

Accordingly, the water droplets formed by the steam coming out of the steam discharge hole 204 falling on the upper surface of the upper housing 200 are guided and drained along the drain passage 238 to the steam discharge hole 204 .

In particular, the upper surface of the upper housing 200 is inclined downward from the front to the rear (α), and the steam discharge hole 204 is located on the rear side of the upper housing 200 .

At this time, the inclination α may be formed very minutely.

This slope (α) provides a natural drainage effect, further increasing the drainage efficiency of the steam cap (100).

The steam discharge hole 204 is formed through concentric circles.

Meanwhile, in the present embodiment, three protrusions 320 are formed to be respectively inserted into the three insertion grooves 210 .

Since one protrusion 320 is formed to have a longer length at both ends than the other two protrusions 320 , erroneous assembly of the upper housing 200 and the lower housing 300 is prevented. At this time, the insertion groove 210 into which the protrusion 320 is inserted is also formed in one and the other two shapes different from each other.

At this time, the misassembly is a combination position such that the steam discharge hole 204 of the upper housing 200 is positioned vertically with the drain hole 318 of the lower housing 300, that is, the steam cap 100 is not functioning properly. It means that the coupling position of the upper housing 200 and the lower housing 300 is misaligned.

In addition, in the coupling position, since the upper housing 200 is inclined downward from the front to the rear, and the bottom 306 of the lower housing 300 is also inclined downward from the front to the rear, the upper housing 200 ) and the lower housing 300 to be positioned side by side in an inclined direction is also included.

Meanwhile, the steam cap 100 of this embodiment further includes a first display unit 501 formed on the outer peripheral surface of the upper housing 200 and a second display unit 502 formed on the outer peripheral surface of the lower housing 300 .

At this time, when the upper housing 200 and the lower housing 300 are combined, the first display unit 501 and the second display unit 502 are formed to be parallel to each other in the vertical direction. Therefore, it is convenient to be able to couple the upper housing 200 and the lower housing 300 to each other at the correct position just by looking at the display unit 500 .

In addition, since the lower side of the first display unit 501 is formed in a triangle, it guides to locate the second display unit 502 where the angled portion points, so it is convenient to use.

On the other hand, the upper plate 206 of the upper housing 200 has a flange on which a finger catches when pulling out the steam cap 100 seated in the seating groove 60 , more specifically, a protrusion is formed on the lower surface of the flange.

At this time, the flange protrudes outward than the side wall 208 .

On the other hand, the bottom 306 of the seating groove 60 is formed with support parts 61 protruding upward from all sides, and the steam cap 100 seated in the seating groove 60 is placed on the support part 61 . .

In addition, since a recessed separation groove 70 is formed in the seating groove 60, when the user puts a finger into the separation groove 70 and lifts the steam cap 100 while spanning the flange or protrusion, the steam cap ( 100) is separated from the seating groove (60).

As described above, although described with reference to preferred embodiments of the present invention, those of ordinary skill in the art may vary the present invention within the scope without departing from the spirit and scope of the present invention described in the claims below. It can be implemented by changing or modifying it.
