The pressing surface 630A may be in contact with the locker 500.

The pressing surface 630A may have a surface inclined toward the button holding portion 610 as it moves toward the nearby locker support portion 520. For example, the pressing surface 630A may have a tapered shape. The pressing surface 630A may be inclined toward the button holding portion 610 as it moves forward. The pressing surface (630A) may be inclined to get closer to the button exposure hole (420H) as it moves forward.

The rocker supporter unit 520 may be guided to move along the pressing surface 630A. While the button 600 is moved from the first button position to the second button position, the locker supporter portion 520 may be moved along the pressing surface 630A. By this, the locker 500 can be moved from the locking position to the unlocking position.

In order for the rocker supporter portion 520 to move along the pressing surface 630A, the pressing surface 630A may be inclined.

The pressing surface 630A may be inclined toward the control panel 41 in a direction from the first button position of the button 600 to the second button position.

Pressure surface 630A may have an angle substantially between 20 and 50 degrees and less than or equal to 45 degrees. Through this, the button 600 can be easily moved along the pressing surface 630A.

The pressing protrusion 630 may be positioned to be spaced apart from the button hook 620. A seating gap may be provided between the pressing protrusion 630 and the button hook 620. A button elastic member 601 may be inserted into the seating gap.

The button elastic member 601 may be positioned between the support flange 611 and the locker supporter portion 520.

A portion of the button elastic member 601 may be located in the seating gap. By this, the position of the button elastic member 601 can be fixed.

FIG. 13 is an exploded view showing the knob assembly N shown in FIG. 9 cut along line VIII-VIII' of FIG. 9 when the button 600 is at the first button position. FIG. 14 is an exploded view showing the button 600 of the knob assembly N shown in FIG. 13 cut when it is in the second button position.

With reference to FIGS. 13 and 14 , the movement of the locker 500 according to an embodiment of the present disclosure will be described.

The locker 500 can be moved to a locking position and an unlocking position.

Button 600 can be moved to a first button position and a second button position.

Referring to FIG. 13, the locker 500 may be exposed to the outside of the weight 700 when in the locking position. That is, the locker contact portion 510 may be exposed to the outside of the weight 700 when the locker 500 is in the locking position.

When the locker 500 is in the locking position, as the locker elastic member 501 presses the locker 500, the locker contact portion 510 may be exposed to the outside of the weight 700.

The movement of the button 600 may be restricted to the outside of the knob 400 from the first button position. This is because the support flange 611 of the button 600 contacts the inside of the knob 400, thereby restricting the movement of the button 600.

The button 600 may be exposed to the outside of the knob 400 at the first button position.

The button 600 is exposed to the outside of the knob 400 at the first button position because the button elastic member 601 presses the button 600 from the second button position to the first button position. You can. That is, the button holding portion 610 may be exposed to the outside of the knob 400 when the button 600 is in the first button position.

Furthermore, when the button 600 is in the first button position, the locker elastic member 501 may press the locker 500 toward the rear. While the locker 500 is pressed toward the rear, the locker supporter unit 520 may press the pressing protrusion 630 toward the outside of the knob 400. This is because the locker supporter portion 520 is in contact with the pressing surface 630A. While the locker supporter unit 520 presses the pressing surface 630A, the pressing surface 630A is inclined, so the force applied by the locker supporter unit 520 can press the locker 500 to the outside of the knob 400. there is.

Referring to FIG. 14 , when the locker 500 is in the unlocking position, less may be exposed to the outside of the weight 700 than when it is in the locking position. That is, the locker contact portion 510 may be moved inside the knob 400 when the locker 500 is in the unlocked position compared to when the locker 500 is in the locked position.

When the locker 500 is in the unlocked position, the inward movement of the knob 400 may be limited by the maximum compression distance of the locker elastic member 501.

The movement of the button 600 may be restricted to the inside of the knob 400 at the second button position. This is because the pressing protrusion 630 of the button 600 comes into contact with the button movement limiter 421 of the knob 400. Additionally, the support flange 611 of the knob 400 may press the locker supporter portion 520 of the locker 500 toward the button movement limiting portion 421 of the knob 400. Even if the support flange 611 presses the locker supporter part 520 to the button movement limiting part 421 of the knob 400, the button movement limiting part 421 of the knob 400 and the locker supporter part 520 are in contact. Therefore, the movement of the locker 500 may be restricted. Since the movement of the locker 500 is restricted, the movement of the button 600 may be restricted.

Button 600 may be less exposed to the outside of knob 400 in the second button position than in the first button position. The button 600 may be pushed further into the knob 400 at the second button position than at the first button position.

The button 600 may press the locker 500 forward while the button 600 moves from the first button position to the second button position. While the locker 500 is pressed forward, the locker supporter portion 520 may be pressed by the pressing surface 630A of the pressing protrusion 630.

While the locker 500 is moved from the locking position to the unlocking position, the locker supporter part 520 is in contact with the pressing surface 630A and can be moved forward. Since the pressing surface 630A is inclined, the rocker supporter unit 520 can be moved along the inclined pressing surface 630A.

The movement of the button 600 from the first button position to the second button position may be similar to the user pushing the button 600.

By moving the button 600 from the first button position to the second button position, the locker 500 can be moved from the locking position to the unlocking position.

The movement of the button 600 from the second button position to the first button position may be similar to the user not pushing the button 600.

By moving the button 600 from the second button position to the first button position, the locker 500 can be moved from the unlocked position to the locked position.

At this time, moving the button 600 from the second button position to the first button position can be viewed as going through the opposite process of moving the button 600 from the first button position to the second button position.

Previously, the movement of the salpin locker 500 will be explained in relation to the locking hole 41HH (FIG. 15) of the control panel 41.

FIG. 15 shows the knob assembly N shown in FIG. 9 mounted on the shaft 300 of the regulator device R when the button 600 is in the first button position, taken along line ⅩV-ⅩV' of FIG. 2. This is a cross-sectional view. FIG. 16 is a cross-sectional view illustrating the knob assembly N of FIG. 15 when the button 600 is in the second button position. FIG. 17 is a cross-sectional view illustrating the knob assembly N of FIG. 16 when the knob 400 moves from the first knob position to the second knob position.

15 to 17, the movement of the knob assembly (N) and the regulator device (R) according to an embodiment of the present disclosure will be described.

As seen above, while the button 600 is moved from the first button position to the second button position, the locker 500 may be moved from the locking position to the unlocking position. While the locker 500 is in the locking position, the rotation of the knob 400 may be restricted. If the rotation of the knob 400 is restricted, the rotation of the shaft 300 may be restricted.

The shaft 300 may be rotated only when it is moved from the first shaft position to the second shaft position. Only when the shaft 300 is rotated can the regulator device (R) operate the heating source (90). This is because, as discussed above, the stopper 320 of the shaft 300 needs to be separated from the stopper groove 111H.

The shaft 300 may be combined with the knob 400. While shaft 300 is moved from the first shaft position to the second shaft position, knob 400 may be moved from the first knob position to the second knob position.

As an example, the position of the knob 400 shown in FIG. 15 may be regarded as the first knob position. The position of the knob 400 shown in FIG. 17 can be viewed as the second knob position.

When knob 400 is in the second knob position, shaft 300 may be in the second shaft position. When the knob 400 is in the second knob position, the knob 400 may be rotated to rotate the shaft 300.

When the rotation of the knob 400 is restricted at the second knob position, the rotation of the shaft 300 may be restricted. In this case, it may be difficult for the regulator device R to operate the heating source 90.

The locker 500 may limit the rotation of the knob 400, thereby limiting the operation of the regulator device (R).

Referring to FIGS. 15 and 16 , while the button 600 is moved from the first button position to the second button position, the locker 500 may be moved from the locking position to the unlocking position.

When the locker 500 is in the locking position, the locker 500 may or may not be inserted into the locking hole 41HH. However, when the locker 500 is inserted into the locking hole 41HH, as will be described later, when the knob 400 is at the second knob position, the locker 500 needs to be removed from the locking hole 41HH. Since the distance that 500 must be moved becomes long, the locker 500 is preferably not inserted into the locking hole 41HH, or only the end of the locker 500 may be inserted into the locking hole 41HH. .

While button 600 is moved from the first button position to the second button position, locker 500 may be moved from the locking position toward the unlocking position.

While the button 600 is moved from the first button position to the second button position, the locker 500 may be moved forward.

While the button 600 is moved from the first button position to the second button position, the locker contact portion 510 may be moved in a direction away from the control panel 41.

When the button 600 is moved to the second button position, the locker 500 may be separated from the locking hole 41HH.

Referring to FIG. 17 , the knob 400 may be moved from the first knob position to the second knob position while the shaft 300 is moved from the first shaft position to the second shaft position.

While the knob 400 is moved from the first knob position to the second knob position, the knob 400 may become closer to the control panel 41 . While the knob 400 is moved from the first knob position to the second knob position, the knob 400 may become closer to the locking hole 41HH.

While the knob 400 is moved from the first knob position to the second knob position, the locker 500 may become closer to the locking hole 41HH. However, the locker 500 may not be inserted into the locking hole 41HH.

When the locker 500 is inserted into the locking hole 41HH, when attempting to rotate the knob 400, the locker 500 may contact the control panel 41 adjacent to the locking hole 41HH. As a result, rotation of the knob 400 may be restricted. If the rotation of the knob 400 is restricted, the rotation of the shaft 300 may be restricted. If rotation of the knob 400 is restricted, it may be difficult for the regulator device R to operate the heating source 90.

When the locker 500 is not inserted into the locking hole 41HH, the knob 400 may be rotatable. By this, the regulator device (R) can operate the heating source (90).

That is, when the button 600 is in the second button position, the knob 400 can be rotated and the regulator device R can operate the heating source 90.

Accordingly, when the button 600 is not pressed, malfunction of the heating source 90 can be prevented. When the user presses the button 600 according to intention, the heating source 90 can be operated for the first time.

Above, the cooking appliance 1 according to an embodiment of the present disclosure has been described. Hereinafter, a cooking appliance 1 according to another embodiment of the present disclosure will be described. Configurations that are the same as those shown in FIGS. 1 to 17 may be assigned the same reference numerals and descriptions may be omitted.

Figure 18 is a cross-sectional view showing the knob assembly (N-1) of the cooking appliance 1 and its related configuration according to an embodiment of the present disclosure.

With reference to FIG. 18, a locker 500-1 according to an embodiment of the present disclosure will be described.

The locker 500-1 may be inserted into the control panel 41 by penetrating the locking hole 41HH at the locking position.

The locker 500-1 may be positioned through the locking hole 41HH in the locking position while the knob 400 is in the first knob position.

The end of the locker 500 shown in FIGS. 1 to 17 could be received in the locking hole 41HH while the knob 400 is in the first knob position. In this case, the end of the locker 500 may not be located inside the control panel 41.

In this embodiment, the end of the locker 500-1 may be positioned through the locking hole 41HH at the locking position while the knob 400 is in the first knob position. In this case, the end of the locker 500-1 may be located inside the control panel 41.

When the end of the locker 500-1 is located inside the control panel 41, the rotation of the knob 400 may be restricted even while it is in the first knob position. As a result, the user can easily see that it is difficult to operate the cooking appliance 1 without pressing the button 600.

That is, the locker contact portion 510-1 of the locker 500-1 may be inserted into the locking hole 41HH while the button 600 is in the first button position.

Figure 19 is a cross-sectional view showing the knob assembly (N-2) of the cooking appliance 1 according to an embodiment of the present disclosure.

With reference to FIG. 19, a button 600-2 according to an embodiment of the present disclosure will be described.

Button 600-2 may include a pressing protrusion 630-2. The pressing protrusion 630-2 may have a pressing surface 630A-2.

Pressure surface 630A-2 may be in contact with locker 500. The pressing surface 630A-2 may be in contact with the locker supporter portion 520 of the locker 500.

The pressing surface 630A-2 may have a curvature. The center of curvature of the pressing surface 630A-2 may be located in a direction toward the control panel 41. The pressing surface 630A-2 may have a convex shape in a direction away from the control panel 41.

When the pressing surface (630A-2) is a curved surface, the locker 500 is initially difficult to change position while moving from the locking position to the unlocking position, and then the locker 500 is moved toward the unlocking position to some extent. , it can be easy to change the location. This is because, when the pressing surface 630A-2 is a curved surface, the slope on the side close to the locker 500 is steep, but the slope on the side away from the locker 500 is gentle.

In other words, while the button 600-2 is moved from the first button position to the second button position, it is difficult to change the position at first, but when the button 600-2 is moved toward the second button position to some extent, , which may mean that location changes can become easier. Accordingly, when attempting to press the button 600-2 by mistake, malfunction is prevented because the initial movement of the button 600-2 is difficult, and when the button 600-2 is pressed intentionally, the button 600-2 is pressed to some extent. After the button 600-2 is moved, the button 600-2 can be easily moved to facilitate operation.

In the case of the embodiment shown in FIGS. 1 to 17, the pressing surface 630A of the button 600 is flat, and thus shows a movement different from the movement of the button 600-2 according to the embodiment of the present disclosure. There is a difference.

Figure 20 is a cross-sectional view showing the knob assembly (N-3) of the cooking appliance 1 according to an embodiment of the present disclosure.

With reference to FIG. 20, a knob assembly (N-3) according to an embodiment of the present disclosure will be described.

When the button 600 is moved from the first button position to the second button position, the locker 500 may be moved from the locking position to the unlocking position along the pressing surface 630A.

When the button 600 is at the second button position, the locker 500 can receive an elastic force that moves it from the unlocked position to the locked position by the locker elastic member 501.

When the locker 500 is moved from the unlocking position to the locking position, the locker supporter unit 520 is moved to the unlocking position along the pressing surface 630A, so that the button 600 is moved from the second button position to the first button position. It can be moved to the button position. That is, if the locker elastic member 501 has sufficient elastic force, the button 600 can be moved from the second button position to the first button position even without the button elastic member 601.

1 to 17 , the knob assembly N may include a button elastic member 601 to move the button 600 from the second button position to the first button position. The knob assembly (N-3) in this embodiment is different in that the button 600 can be moved from the second button position to the first button position without the button elastic member 601.

Figure 21 is a cross-sectional view showing the knob assembly (N-4) of the cooking appliance 1 and its related configuration according to an embodiment of the present disclosure.
