The sliding of the slide rod 2 along the through groove 3 will be described next. Fig. 4 is a perspective view of a cooking appliance according to an embodiment of the present invention, fig. 5 is a partial enlarged view of a component a in fig. 4, fig. 6 is a perspective view of a slide bar in the cooking appliance according to an embodiment of the present invention, fig. 7 is a partial enlarged view of a component B in fig. 6, and fig. 8 is a cross-sectional view showing a condition that the slide bar and a through groove are mutually matched in the cooking appliance according to an embodiment of the present invention. As shown in fig. 4 and 5, the groove wall is provided with a convex portion 31. Through being equipped with bellying 31 on the cell wall that runs through, slide bar 2 is along running through the gliding in-process of groove 3, slide bar 2 experiences and rises to bellying 31 from lower cell wall, reduce the process of cell wall again, consequently, slide bar 2's slip has the process that a sliding resistance increases, it too much or not in place to lead to the comparatively complicated process of accommodation process to be difficult to appear slide bar 2, and in the accommodation process, along with slide bar 2's narrow range goes up and down, user's operation is felt also preferred, consequently, user uses and experiences better. The shape of the boss 31 is not limited, and for example, as shown in fig. 5, the boss 31 has an arc surface, that is, a relatively smooth surface is formed, so that when the slide rod 2 slides in the through groove 3, the contact with the boss 31 is relatively smooth, and noise and the like can be reduced.

Furthermore, the utility model discloses an among the specific embodiment, bellying 31 is two at least, and two at least bellyings 31 are arranged along slide bar 2's slip direction, and the increase of bellying 31 number can all produce the resistance to slide bar 2's slip in the longer range that runs through groove 3 to can make slide bar 2 gliding in-process pass through bellying 31 one by one.

Illustratively, as shown in fig. 5, the through groove 3 has a protrusion 31 extending to the whole groove wall on one side of the groove wall, for example, on the lower groove wall, so that the user can feel resistance when operating the sliding rod 2 by hand, and the operation is more comfortable, no matter how the user adjusts the sliding rod 2.

When the extending direction of the through groove 3 is parallel to the bottom of the housing 1, the slide bar 2 is generally in contact with the lower groove wall of the through groove 3 due to gravity, and when the user operates the portion of the slide bar 2 exposed from the housing 1, it is customary to push the slide bar 2 to slide while pressing the slide bar 2 downward, and therefore the slide bar 2 is in contact with the lower groove wall of the through groove 3, and therefore, the boss portion 31 can be selectively provided on the lower groove wall of the through groove 3. Considering that the operation habits of some people may be different, the sliding rod 2 may be pushed to slide while being lifted upwards, and therefore, the protrusion 31 may be disposed on the upper groove wall of the through groove 3, and of course, the protrusion 31 may be disposed on both the lower groove wall and the upper groove wall to meet the use requirements of people with different habits.

It will be appreciated that in other examples at least two protrusions 31 are provided on the same sliding-direction groove wall extending through the groove 3. That is, if the protrusions 31 are provided on the groove wall of the through groove 3, it is preferable that all of the protrusions 31 are provided on the same groove wall so that more protrusions 31 come into contact with the same surface of the slide bar 2 and can simultaneously exert a resistance action on the sliding of the slide bar 2.

As shown in fig. 6, 7 and 8, in the embodiment of the present invention, the slide rod 2 is provided with a rib 21, and the rib 21 is a structure protruding from the surface of the slide rod 2, and may be integrally formed on the outer surface of the slide rod 2, or an independent rib 21 member may be fixed on the outer surface of the slide rod 2 by welding or bonding.

In addition, the rib 21 is required to be in sliding contact with the groove wall, specifically, the rib 21 on the slide bar 2 and the protrusion 31 on the groove wall are in contact with each other during the sliding of the slide bar 2. Therefore, on the basis of the lug boss 31 arranged on the groove wall, the convex rib 21 is further arranged on the slide rod 2, in the sliding process of the slide rod 2 along the through groove 3, the convex rib 21 is in contact with the lug boss 31, the resistance of the slide rod 2 during sliding is further increased, not only is the accurate adjustment of the slide rod 2 facilitated, but also the user feels more during operation, and the use experience of the user is improved.

Further, as described above, in the case that there are at least two protrusions 31, a groove 32 may be formed between adjacent protrusions 31, and the rib 21 may extend into the groove 32 during the sliding. When the arrangement is carried out, the convex rib 21 on the sliding rod 2 enters the groove 32 along with the sliding of the sliding rod 2 and then slides to the top end of the convex part 31 along the wall of the groove 32, so that the sliding process of the sliding rod 2 is stable. Illustratively, the distance between the protrusions 31 is equal, so that the contour dimension of each groove 32 is substantially the same, and the resistance to the ribs 21 is uniform, and does not increase or decrease suddenly. It will be appreciated that, in order to enable a better fit between the rib 21 and the groove 32, the rib 21 may be arranged at a height relative to the surface of the slide bar 2 which is substantially equal to the depth of the groove 32, or slightly greater than the depth of the groove 32.

Further, the outer contour shape of the rib 21 matches the shape of the groove 32. Thus, the rib 21 is stable when entering the groove 32, and does not shake sideways or forward and backward. In fig. 8, it is shown that when the cross section of the bead 21 is in the shape of a peak, the shape of the groove 32 between the adjacent protrusions 31 is in the shape of a valley. In other examples, the cross-sectional shape of the rib 21 may be triangular, and the cross-sectional shape of the groove 32 may be triangular.

In the embodiment of the present invention, the surface of the rib 21 and the surface of the protruding portion 31 are arc surfaces. This allows the surface of the rib 21 of the slide rod 2 to be formed into a smooth surface, so that the contact between the rib 21 and the boss 31 is smooth when the slide rod 2 slides in the through-groove 3. Noise and the like can be reduced.

Of course, one of the surface of the rib 21 and the surface of the protrusion 31 may be an arc-shaped surface, and the other may not be an arc-shaped surface.

In the present embodiment, the boss 31 and/or the rib 21 each extend in the wall thickness direction of the housing 1. Since the sliding rod 2 rotates around a position in the housing 1, for example, around the supporting frame, when the sliding rod 2 slides, specifically, at a position on the sliding rod 2 contacting the through groove 3, the sliding track of the rib 21 is a partial arc of a circle with a larger diameter, which is substantially equivalent to a straight line, if the extending direction of the protruding portion 31 and the rib 21 is perpendicular to the sliding direction of the sliding rod 2, the sliding rod 2 can be subjected to a larger sliding resistance during the reciprocating sliding of the sliding rod 2.

In other examples, the extension direction of the convex portion 31 and/or the rib 21 may also be at an angle with the wall thickness direction of the housing 1.

Optionally, the extension length of the rib 21 is greater than the wall thickness of the housing 1, so that the rib 21 of the slide rod 2 can be ensured to cooperate with the boss 31 even if there is a radial displacement relative to the housing 1 during the sliding of the slide rod 2. Since the slide rod 2 actually rotates around the support bracket 84, the extension length of the rib 21 is slightly larger than the wall thickness of the housing 1 in consideration of interference with other components in the housing 1.

In other examples, the number of the ribs 21 may be multiple, and the specific number may be selected according to actual needs.

In addition, the cooking appliance 100 further includes a push button 33 connected to the sliding rod 2, the push button 33 is located outside the housing 1, and for example, the push button 33 may be disposed on an end of the sliding rod 2 located outside the housing 1, or may be disposed at a position between two ends of the sliding rod 2 (the position needs to be located outside the housing). Thus, when the slide rod 2 slides in the through slot 3, it is actually rotated relative to the housing 1, and the push button 33 is provided to facilitate manual operation by a user.

As shown in fig. 7, an outer stop 34 is further provided at the interface between the push button 33 and the sliding rod 2, and the outer stop 34 can abut against the outer sidewall of the housing 1 when the sliding rod 2 moves along the through groove 3, especially inward movement along the wall thickness direction of the housing 1 is about to occur, so that the sliding rod 2 can be prevented from further entering the housing 1.

In contrast, an inner stop 35 is also provided at a position of the slide rod 2 corresponding to the rib 21, and the inner stop 35 can abut against the inner side wall of the housing 1 when the slide rod 2 moves along the through groove 3, particularly when outward movement in the wall thickness direction of the housing 1 is about to occur, so that the slide rod 2 can be prevented from further protruding outside the housing 1.

It will be appreciated that the height of the inner stop 35 in the vertical direction is higher than the height of the through slot 3 in order to prevent the transmission of the slide bar 2. In order to facilitate the fitting of the slide rod 2 into the through-going slot 3, the inner stop 35 may be provided as a cantilever-like structure extending from the end of the slide rod 2 and may be elastically deformable in a direction perpendicular to the slide rod 2, i.e. in the vertical direction.

The operation of the cooking appliance 100 of the present application is described below.

When a user needs to adjust the temperature of the cooking device 100, the user holds the push button 33 by hand, and slides the push button 33 along the extending direction of the through groove 3, at this time, the rib 21 on the slide rod 2 intermittently enters and exits the groove 32 between the protrusions 31, so that the slide rod 2 can receive relatively uniform resistance, and on the other hand, the slide rod 2 actually rotates around the supporting frame 84, and the control groove 88 thereof drives the control terminal 831 of the temperature controller 83 to rotate, so as to control the temperature controller 83.

In this embodiment, the cooking utensil includes casing and slide bar, is equipped with the through groove that can supply the slide bar to wear to establish on the casing, and the partial structure of slide bar exposes outside the casing, and the slide bar slides along the extending direction of casing in running through the groove, and the through groove includes the cell wall, cell wall and slide contact, is equipped with the bellying on the cell wall. Through being equipped with the bellying on the cell wall that runs through, the slide bar is along running through the gliding in-process in groove, the slide bar experiences and rises to the bellying from lower cell wall, reduce the process to the cell wall again, consequently, the slip of slide bar has the process that a sliding resistance increases, be difficult to appear the slide bar and slide too much or not in place and lead to the comparatively complicated process of accommodation process, and in the accommodation process, along with the narrow range lift of slide bar, user's operation is felt also preferred, therefore user experience is better.
