2 and 3, the electric thermal pressure cooker 100 of the present invention is largely hinged on the upper side of the rice cooker 110 to cover the rice cooker 110 and the rice cooker 110 in appearance. The rice cooker lid 120 is combined. The inside of the cooker 110 is configured to be seated inside the container 130 containing the food. Inside the rice cooker lid 120 is provided with an inner barrel lid 140 that can overflow the food from the inner barrel 130 or cover the inner barrel 130, between the rice cooker lid 120 and the inner barrel lid 140 A close / separating means is provided to close or close the inner cylinder 130 to the upper side of the inner cylinder lid 140.

In order to closely contact or release the inner cylinder 130 to the inner cylinder lid 140, a moving plate 150 is provided to be slidably moved while being guided by the guide pin 142 protruding on the center of the inner cylinder cap 140. In other words, the guide pin 142 is inserted into the guide groove 152 formed in the moving plate 150 so that the moving plate 150 linearly reciprocates forward and backward from the upper surface of the inner cylinder cover 140.

The handle 160 is located at the rear side of the moving plate 150 and is connected to each other so as to linearly move the moving plate 150 while being pressed or pulled by a hand. That is, one end of the handle 160 is connected to the movable plate 150, and the other end of the handle 160 is installed to be exposed to the outside of the rice cooker lid 120. The handle 160 is guided to be linearly moved by the guide piece 170 fixed to the inner cylinder lid 140, and is inserted horizontally into the first and second coupling grooves 172 and 174 of the guide piece 170. It is.

The latching jaw 154 is formed at the rear side of both sides of the moving plate 150 and the stop protrusion 156 is formed at the front side. That is, the groove 150a is formed in the side surface of the moving plate 150 at the position where the locking jaw 154 and the stop protrusion 156 are adjacent, and one end of the moving lever 180 described below in the groove 150a is formed. It is elastically in contact.

The moving lever 180 is positioned on both side surfaces of the moving plate 150 described above, and the moving lever 180 is interlocked with the linear movement of the moving plate 150 so that the moving plate 150 is moved. It is linearly moved in the direction orthogonal to the movement direction.

The above-mentioned moving lever 180 is guided by the guide piece 144 and the guide pin 146, one end of the moving lever 180 in the side groove 150a of the moving plate 150 by the compression spring 182. It is elastically in contact with, the guide lever 184 is formed in the middle of the moving lever 180, the other end of the moving lever 180 is formed with an opening and closing ring 190 formed integrally with the moving lever 180. .

Opening and closing ring 190 is located on the outer circumferential side of the inner cylinder 130, while the linear movement in the circumferential direction "C" side cross section so as to selectively lock the inner cylinder lid 140 to the inner cylinder 130 It has a shape. That is, the inner cylinder lid 140 is in close contact with the inner cylinder 130 by allowing the outer periphery of the inner cylinder lid 140 and the upper end of the inner cylinder 130 to be inserted into the "c" groove 190a of the opening and closing ring 190. .

Looking at the installation state of the above-described handle 160 in more detail, first inserted into the first and second coupling holes 172, 174 of the guide piece 170 laterally, in the middle of the handle 160 The tension spring 162 is interposed. One end of the tension spring 162 is fixed to the straight stopper 164 formed in the middle of the handle 160, the other end of the tension spring 162 is fixed in the second coupling groove 174 of the guide piece 170. It is. Accordingly, after the elastic force of the tension spring 162 is pushed and the handle 160 is pushed, the force to remove the pushing force is configured to return the handle 160 to the original position by the elastic restoring force of the tension spring 162.

Meanwhile, in order to prevent the handle 160 from being pressed arbitrarily or to keep the handle 160 pressed, the following apparatus is provided. First, the stopper 164 formed in the middle of the handle 160 while the handle 160 is pressed and linearly moved is configured to selectively penetrate the first coupling groove 172. In other words, since the stopper 164 and the first coupling groove 172 are molded in a straight shape, the handle 160 is rotated 90 degrees to match the stopper 164 with the first coupling groove 172. ), The stopper 164 overcomes the elastic force of the tension spring 162 and simultaneously pushes through the first coupling groove 172. As the stopper 164 penetrates the first coupling groove 172, the handle 160 is pushed in the direction of the arrow a, and the force pushing the handle 160 is transmitted to the movable plate 150 again. The moving plate 150 is linearly moved in the direction of an arrow (a) along the guide pin 142.

As the movable plate 150 is linearly moved, the locking jaw 154 of the movable plate 150 overcomes the elastic force of the compression spring 182 and pushes the ends of the movable lever 180 in the circumferential direction, respectively. At this time, the moving lever 180 is moved in the direction of the arrow b while being guided by the guide piece 144.

As the moving lever 180 is moved, the opening / closing ring 190 integrated with the moving lever 180 is opened in the circumferential direction, whereby the inner cylinder 130 and the inner cylinder lid 140 are separable.

On the other hand, after the opening / closing ring 190 is opened and the locking of the opening / closing ring 190 is released, the pressed handle 160 is rotated approximately 90 degrees so that the stopper 164 of the handle 160 of the first coupling groove 172 is opened. It is kept on the back, the movement of the handle 160 is limited by this to maintain the separation state of the opening and closing ring 190.

In this state, when the handle 160 is rotated 90 degrees to its original state, the handle 160 is returned to its original position by the tension spring 162 and at the same time, the opening / closing ring 190 is narrowed as opposed to the above-described operation. ) Will be in close contact with the inner cylinder (130).

Referring to the operation of the electric thermal pressure cooker according to an embodiment of the present invention configured as described above are as follows.

3 and 5 shows that the opening and closing ring 190 is narrowed to the inner cylinder lid 140 to the inner cylinder 130 is in close contact with the inner cylinder lid 140, that is, the opening and closing ring 190 is locked, In the case of opening and closing the opening and closing ring 190 in the state, first, as shown in FIGS. 4 and 6, the stopper 164 formed in the middle of the handle 260 is rotated approximately 90 degrees in one direction. It is matched with the 1st insertion hole 172 of the guide piece 170. When the stopper 164 coincides with the first insertion hole 172, the elastic force of the tension spring 162 may be overcome and the handle 160 may be pressed to allow the stopper 164 to penetrate the first insertion hole 172. As the stopper 164 penetrates through the first insertion hole 172, the handle 160 pushes the moving plate 150. By the pushing force of the handle 160, the moving plate 150 is guided by the guide pin 142 is moved in the arrow direction (a).

At this time, one end of the moving lever 180 is elastically in contact with the groove 150a formed on the side of the moving plate 150, and as the moving plate 150 moves, the locking step 154 of the moving plate 150 is moved. ) Pushes the moving lever 180 in both directions, that is, the direction of the arrow (b). The moving lever 180 is guided by the guide pin 146 by the pushing force of the locking jaw 154 of the moving plate 150 and is moved to both sides. At this time, the opening and closing ring integrally formed at the other end of the moving lever 180 ( 190 is opened in the direction of arrow b.

As the opening / closing ring 190 opens to both sides, the force that brought the inner cylinder cap 140 into close contact with the inner cylinder 130 is removed, and the inner cylinder cap 140 is detachable from the inner cylinder 130.

On the other hand, if you want to maintain the open state of the opening and closing ring 190 in a state in which the handle 160 is pressed, that is, the opening and closing ring 190 is open (shown in FIGS. 4 and 6), the handle 160 is pressed. In this state, the handle 160 is returned to its original state by 90 degrees to maintain the open state of the opening / closing ring 190 by holding the stopper 164 in the guide piece 144 so as not to escape from the first insertion hole 172. It becomes possible.

As described above, in the case where the opening / closing ring 190 is opened (shown in FIGS. 4 and 6) to close the inner cylinder lid 140 to the inner cylinder 130, first, as illustrated in FIGS. 4 and 6. As shown, when the handle 160 is turned by 90 degrees, the stopper 164 coincides with the first insertion hole 172, and at the same time exits the inside of the first insertion hole 172 again by the tension spring 162, and is opposite to the arrow (a). Is moved in the direction. In other words, as the handle 160 is moved in the opposite direction to the arrow a, the moving plate 150 connected to the handle 160 is guided to the guide pin 142 and moved in the opposite direction to the arrow a.

At this time, as the moving lever 180 which is elastically pressed by the locking step 154 formed on the side of the moving plate 150 is returned to its original state, the opening / closing ring 190 formed integrally with the moving lever 180 is inward. By narrowing the opening and closing ring 190 is in close contact with the inner cylinder cover 140 to the inner cylinder (130).

As a result, by moving the handle 160 exposed to the outside of the rice cooker lid 120, the moving plate 150 connected to the handle 160 is moved, and at this time elastically on both sides of the moving plate 150 The moving lever 180 in contact is interlocked, and as the moving lever 180 is interlocked, the opening / closing ring 190 integrally formed on the moving lever 180 is opened, so that the inner cylinder lid 120 and the inner cylinder 130 are closed. The close state will be terminated. In this state, if the inner cylinder lid 140 is to be kept in close contact, turning the handle 160 by 90 degrees overcomes the elastic force of the tension spring 162 and the stopper 164 formed in the middle of the handle 160 is guided. It is to be held on the piece 170. In order to maintain the close contact between the inner cylinder lid 120 and the inner cylinder 130 by narrowing the opening / closing ring 190, when the handle 160 held by the guide piece 170 is turned by 90 degrees, the tension spring 162 The stopper 164 is inserted into the first coupling groove by the elastic force so that the handle 160 moves in the opposite direction to the arrow a, and the movable plate 150 also moves in the opposite direction to the arrow a. Accordingly, the opening and closing ring 190 connected to the moving lever 180 is moved in the opposite direction to the arrow (b) so that the inner cylinder lid 120 can be brought into close contact with the inner cylinder 130.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.

As described above, according to the present invention, since the opening and closing ring is easily opened and closed by pressing the handle and at the same time, there is an advantage of convenience.

In addition, the structure is simple, there is no failure and there is an effect that can reduce the manufacturing cost.
