Description

Technical Field

[0001] This utility model relates to a knob for a stove and a stove. Background Technology

[0002] A knob is a manually operated component that is widely used in various devices. In the cooktop industry, the knob serves as a control button to regulate the use of the cooktop. Specifically, by operating the knob, the cooktop can be turned on or off, and the flame intensity can be adjusted. However, accidental activation can occur during use, such as the knob being accidentally turned on. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned defects in the prior art and provide a knob and a stove for a stove.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A knob for a cooktop, the knob comprising a rotating unit and a fixing unit, the fixing unit being connected to the cooktop panel, and the rotating unit being connected to the fixing unit in a rotatable manner relative to the fixing unit;

[0006] The rotating unit includes a housing, and a limiting structure is provided between the housing and the fixed unit. The limiting structure is used to restrict the rotation of the housing relative to the fixed unit. The limiting structure includes a limiting groove and a limiting buckle, one of which is disposed in the fixed unit and the other is disposed in the housing.

[0007] The outer casing is movable relative to the fixed unit in the direction of the rotation axis of the rotating unit, so that the limiting buckle can disengage from the limiting groove.

[0008] In this design, a limiting structure is installed between the outer casing of the rotating unit and the fixed unit to restrict the rotation of the rotating unit relative to the fixed unit, preventing accidental triggering of the knob. Furthermore, when the outer casing of the rotating unit moves relative to the fixed unit in the direction of the rotation axis, the limiting structure between the outer casing and the fixed unit can be released, thereby enabling the knob to control the stove accordingly.

[0009] Preferably, a portion of the fixing unit extends into the housing, and the outer side wall of the portion of the fixing unit extending into the housing is provided with the limiting groove. The limiting groove extends in a direction parallel to the rotation axis of the rotating unit and passes through the outer side wall of the fixing unit toward the end of the panel. The limiting buckle is provided on the inner surface of the side wall of the housing.

[0010] In this design, the housing contains a partial fixing unit, so that the housing and the fixing unit overlap in the direction along the rotation axis. The limiting structure is set in the overlapping area to prevent the limiting structure from being exposed, so that the knob has a consistent external structure.

[0011] Preferably, the outer shell is a cylindrical structure with outer shell sidewalls and outer shell endwalls, and the limiting buckle is disposed on the edge of the outer shell sidewall, the limiting buckle extends toward the limiting groove and into the limiting groove.

[0012] Preferably, the first surface of the limiting buckle facing the limiting groove is a plane.

[0013] Preferably, in the rotation direction of the rotating unit, the two opposing second surfaces of the limiting buckle are planes.

[0014] Preferably, the upper end of the limiting buckle is provided with a guide structure along the extension direction of the limiting groove.

[0015] In this solution, by adopting the above structure, it is easy for the limit buckle to enter the limit groove.

[0016] Preferably, along the extending direction of the limiting groove, the lower end of the limiting buckle is provided with an inclined surface that slopes upward toward the interior of the outer shell.

[0017] Preferably, the fixing unit has a circumferential ring portion that protrudes along the radial direction of the fixing unit, and the lower end face of the circumferential ring portion is spaced from the surface of the fixing unit for connection with the stove; the limiting groove is disposed in the circumferential ring portion, and the lower end face of the circumferential ring portion is used to abut against the upper end face of the limiting buckle.

[0018] In this solution, by adopting the above-described structural form, the circumferential ring portion can serve as a component for setting the limiting groove. Furthermore, the lower end face of the circumferential ring portion has a gap with the connecting surface of the fixing unit, which provides space for the limiting buckle to move away from the limiting groove. Additionally, the lower end face of the circumferential ring portion can also serve as a limiting surface for the limiting buckle, restricting the limiting buckle from moving along the direction of the rotation axis.

[0019] Preferably, the fixing unit has a portion with the limiting groove and a protrusion at the through end of the limiting groove, the protrusion being disposed on the lower end face of the circumferential ring portion.

[0020] In this solution, the shell is prevented from resetting and springing back when rotated at a small angle, allowing users to actively reassemble the shell and experience a difference in feel.

[0021] Preferably, the fixing unit includes a bracket and a fastener, the bracket being fixedly connected to the panel by the fastener; a portion of the bracket extends into the housing; and the outer side wall of the bracket has a stepped structure.

[0022] Preferably, the rotating unit further includes a push rod portion and an inner shell portion. The outer shell is made of a conductive material. Both the push rod portion and the inner shell portion are disposed inside the outer shell and connected to the outer shell. The push rod portion is located in the central region of the outer shell, and the inner shell portion is located in the radial end region of the outer shell.

[0023] The top rod portion has a conductive material for forming a conductive path with the outer shell and the panel. The inner shell portion has a conductive part, one end of which contacts the outer shell and the other end extends to the surface of the inner shell portion facing the panel for contacting the panel.

[0024] In this design, the outer shell and top rod portion serve as part of a conductive path, while the conductive part of the inner shell and the outer shell serve as part of another conductive path. Thus, when the knob is installed on the cooktop panel, user operation creates a conductive path between the top rod portion and the conductive part. This allows the cooktop panel to collect signals at the center and radial end areas of the knob, respectively, and the knob's rotation angle can be determined from these signals. Furthermore, the knob is mounted to the cooktop panel via a fixing unit. The formation of these two conductive paths eliminates the need for perforated wiring, thereby improving the ease of use of the knob.

[0025] Preferably, the inner shell portion has a gap between the plane of the surface facing the panel, the plane of the surface where the fixing unit connects to the panel, and the direction of the rotation axis of the rotating unit.

[0026] In this scheme, when the outer shell of the rotating unit moves relative to the fixed unit in the direction of the rotation axis, the limit between the outer shell and the fixed unit is released, and the inner shell part contacts the panel, thereby performing corresponding detection and control.

[0027] A cooktop includes a knob as described above, and the cooktop includes a touchscreen, the knob being mounted on the touchscreen.

[0028] The positive and progressive effects of this invention are as follows: A limiting structure is provided between the outer shell of the rotating unit and the fixed unit, which restricts the rotation of the rotating unit relative to the fixed unit, preventing accidental triggering of the knob. Furthermore, when the outer shell of the rotating unit moves relative to the fixed unit in the direction of the rotation axis, the limiting structure between the outer shell and the fixed unit can be released, thereby enabling the knob to control the stove accordingly.

Detailed Implementation

[0039] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0040] This embodiment provides a knob 1 for a stove, such as... Figure 1 As shown, the knob 1 can be installed on the touchscreen 2 of the cooktop, such as on the glass panel 3. The knob 1 has a metal touch to simulate the interaction between the user's finger and the touchscreen 2. In practice, the knob 1 can be connected to the panel 3 by a fastener 500 similar to a screw, or it can be connected to the panel 3 by adhesive fastening.

[0041] like Figure 2 and Figure 3As shown, the knob 1 includes a rotating unit 10 and a fixing unit 20. The fixing unit 20 is used to connect to the panel 3 of the stove. The rotating unit 10 is connected to the fixing unit 20 in a rotatable manner relative to the fixing unit 20. When the knob 1 is installed on the panel 3, the fixing unit 20 can be fixed relative to the panel 3, and the rotating unit 10 can be driven by the user to rotate relative to the fixing unit 20, that is, relative to the panel 3.

[0042] The rotating unit 10 includes a housing 100, and a limiting structure is provided between the housing 100 and the fixed unit 20. The limiting structure is used to restrict the rotation of the housing 100 relative to the fixed unit 20. The limiting structure includes a limiting groove 410 and a limiting buckle 140, one of which is disposed in the fixed unit 20 and the other in the housing 100. The housing 100 is movable relative to the fixed unit 20 in the direction of the rotation axis R of the rotating unit 10, so that the limiting buckle 140 can disengage from the limiting groove 410.

[0043] A limiting structure is provided between the outer shell 100 of the rotating unit 10 and the fixed unit 20 to restrict the rotation of the rotating unit 10 relative to the fixed unit 20, preventing accidental triggering of the knob 1. Furthermore, when the outer shell 100 of the rotating unit 10 moves relative to the fixed unit 20 in the direction of the rotation axis R, the limiting structure between the outer shell 100 and the fixed unit 20 can be released, allowing the knob 1 to control the stove accordingly. In specific implementations, the outer shell 100, as a component of the rotating unit 10, can be directly operated by the user. Other components may be provided inside, such as the top rod portion 200 and the inner shell portion 300 described below. Further, a portion of the fixed unit 20 can extend into the outer shell 100. The limiting structure can be provided between the portion of the fixed unit 20 extending into the outer shell 100 and the outer shell 100, thereby facilitating the arrangement of the limiting structure and the application of the limiting effect.

[0044] like Figure 3 , Figure 4 and Figure 5 As shown, a portion of the fixing unit 20 extends into the housing 100. The outer wall of the portion of the fixing unit 20 extending into the housing 100 is provided with a limiting groove 410. The limiting groove 410 extends in a direction parallel to the rotation axis R of the rotating unit 10 and passes through the end of the outer wall of the fixing unit 20 facing the panel 3. A limiting buckle 140 is provided on the inner surface of the side wall of the housing 100. The housing 100 accommodates a portion of the fixing unit 20, so that the housing 100 and the fixing unit 20 overlap in the direction along the rotation axis R. The limiting structure is provided in this overlapping area to prevent the limiting structure from being exposed, thus giving the knob 1 a consistent external structure.

[0045] like Figure 3 , Figure 5 and Figure 7As shown, the outer casing 100 has a cylindrical structure, with a side wall 121 and an end wall 122. A limiting buckle 140 is disposed on the edge of the side wall 121, extending towards and into the limiting groove 410. Figure 5 and Figure 7 As shown, the limiting buckle 140 is located at the lower edge of the inner surface of the outer casing sidewall 121 and has a hook-shaped structure.

[0046] Furthermore, such as Figure 4 and Figure 5 As shown, on opposite sides of the knob 1 in the radial direction, the inner surface of the outer casing sidewall 121 is provided with a limiting buckle 140, and correspondingly, the outer sidewall of the fixing unit 20 is provided with a limiting groove 410.

[0047] In specific implementations, the limit buckle 140 can have various structural forms. The following embodiments provide some specific implementation methods. The limit buckle 140 can have one or more of the following structures. For example... Figure 5 and Figure 7 As shown, a structural diagram is illustrated when the following structures are simultaneously present.

[0048] like Figure 5 and Figure 7 As shown, the first surface 141 of the limiting buckle 140 facing the limiting groove 410 is a plane. The bottom surface 411 of the limiting groove 410 opposite to the first surface can be arc-shaped, plane, or other structural forms.

[0049] like Figure 7 As shown, in the rotation direction of the rotating unit 10, the two opposing second surfaces 142 of the limiting buckle 140 are planes. The groove sidewalls 412 of the limiting groove 410 opposite to the second surfaces can be planes, arc-shaped, or other structural forms.

[0050] like Figure 7 As shown, along the extending direction of the limiting groove 410, the upper end of the limiting buckle 140 is provided with a guide structure 143. This facilitates the limiting buckle 140 entering the limiting groove 410. Preferably, the guide structure 143 has a structure that protrudes upward in the middle 421 and slopes downward on both sides.

[0051] like Figure 7 As shown, along the extension direction of the limiting groove 410, the lower end of the limiting buckle 140 is a third surface 144, which is an inclined surface that slopes upward toward the inside of the outer shell 100.

[0052] In specific implementation, the limiting groove 410 can have a variety of implementation methods. Some specific implementation methods are provided in the following embodiments. The limiting buckle 140 can have one or more of the following structures.

[0053] like Figure 2, Figure 3 , Figure 5 and Figure 6 As shown, the fixing unit 20 has a circumferential ring portion 420, which protrudes along the radial direction of the fixing unit 20. The lower end face 422 of the circumferential ring portion 420 is spaced from the surface of the fixing unit 20 for connection with the stove. A limiting groove 410 is provided in the circumferential ring portion 420, and the lower end face 422 of the circumferential ring portion 420 is used to abut against the upper end face of the limiting buckle 140. The circumferential ring portion 420 can serve as a component for setting the limiting groove 410. Furthermore, the lower end face 422 of the circumferential ring portion 420 is spaced from the connecting surface of the fixing unit 20 to provide space for the limiting buckle 140 to move away from the limiting groove 410. Additionally, the lower end face 422 of the circumferential ring portion 420 can also serve as a limiting surface of the limiting buckle 140, restricting the limiting buckle 140 from moving along the direction of the rotation axis R.

[0054] like Figure 4 and Figure 6 As shown, the fixing unit 20 has a portion with a limiting groove 410, and a protrusion 421 is provided at the through end of the limiting groove 410. The protrusion 421 is located on the lower end face 422 of the circumferential ring portion 420. This prevents the outer shell 100 from resetting and springing back when rotated at a small angle, allowing the user to actively reattach the outer shell 100 and creating a tactile difference.

[0055] like Figure 5 and Figure 6 As shown, the fixing unit 20 includes a bracket 400 and a fastener 500. The bracket 400 is fixedly connected to the panel 3 by the fastener 500. A portion of the bracket 400 extends into the housing 100. The outer wall of the bracket 400 has a stepped structure.

[0056] Furthermore, such as Figure 5 As shown, the stepped structure is a structure whose radial dimension gradually increases from bottom to top. The aforementioned circumferential ring portion 420 can be the outermost radial protrusion 421 portion of the stepped support 400, located in the upper region of the support 400. The limiting groove 410 extends along the direction of the rotation axis R, that is, extends vertically, and penetrates the circumferential ring portion 420. The protrusion 421 is provided at two positions on the lower end face 422 of the circumferential ring portion 420 adjacent to the limiting groove 410, and the protrusion 421 protrudes downward. Furthermore, when the limiting buckle 140 moves within the limiting groove 410, when it has the aforementioned guide structure, the guide structure can pass over the protrusion 421 and abut against the lower end face 422 of the circumferential ring portion 420.

[0057] like Figure 2 and Figure 3As shown, the rotating unit 10 includes a push rod portion 200 and an inner shell portion 300. Both the push rod portion 200 and the inner shell portion 300 are disposed within and connected to the outer shell 100. The push rod portion 200 is located in the central region of the outer shell 100, and the inner shell portion 300 is located in the radial end region of the outer shell 100. Figure 1 As shown, the knob 1 has a flattened cylindrical structure. The rotating unit 10 can rotate relative to the rotation axis R, which is the central axis of the rotating unit 10. Figure 2 and Figure 3 As shown, the outer shell 100 has a generally cylindrical structure. The top rod portion 200 and the inner shell portion 300 are both disposed in the internal space of the outer shell 100. When the outer shell 100 is rotated by the user, the top rod portion 200 and the inner shell portion 300 can rotate with the outer shell 100.

[0058] The outer shell 100 is made of a conductive material. The top rod portion 200 has a conductive material for forming a conductive path with the outer shell 100 and the panel 3. The inner shell portion 300 has a conductive part 310 inside, one end of which contacts the outer shell 100, and the other end extends to the surface of the inner shell portion 300 facing the panel 3 for contact with the panel 3. The top rod portion 200 may be made of a conductive material or may contain conductive material, so that the top rod portion 200 can form a conductive path with the outer shell 100. The other parts of the inner shell portion 300, except for the conductive part 310, are made of a non-conductive material, so that the inner shell portion 300 forms a conductive path with the outer shell 100 at the location of the conductive part 310.

[0059] The outer casing 100 and the top rod portion 200 can serve as part of a conductive path, while the conductive portion 310 of the inner casing portion 300 and the outer casing 100 can serve as part of another conductive path. Thus, when the knob 1 is installed on the cooktop panel 3, a conductive path can be formed at the top rod portion 200 and the conductive portion 310 through user operation. This allows the cooktop panel 3 to collect signals at the center area and radial end area of ​​the knob 1, respectively, and the rotation angle of the knob 1 can be determined based on these signals. Furthermore, the knob 1 is installed on the cooktop panel 3 via the fixing unit 20. The formation of two conductive paths eliminates the need for perforated wiring, thereby improving the ease of use of the knob 1.

[0060] like Figure 5 and Figure 8 As shown, the center point of the contact portion between the top rod portion 200 and the panel 3 coincides with the rotation axis R of the rotating unit 10. When the user rotates the knob 1, the contact portion between the top rod portion 200 and the panel 3 does not change, while the conductive part 310 of the inner shell portion 300 rotates with the user's operation, thus facilitating angle calculation.

[0061] like Figure 5and Figure 8 As shown, the inner shell portion 300 has a gap in the plane containing the surface of the panel 3, the plane containing the surface of the fixing unit 20 connected to the panel 3, and in the direction of the rotation axis R of the rotating unit 10. When the outer shell 100 of the rotating unit 10 moves relative to the fixing unit 20 in the direction of the rotation axis R, the limiting position between the outer shell 100 and the fixing unit 20 is released, and the inner shell portion 300 contacts the panel 3, thereby performing corresponding detection and control. Further, as... Figure 2 , Figure 3 and Figure 8 As shown, the conductive part 310 includes a conductive sheet 311 and an elastic member 312. The conductive sheet 311 is laid on the surface of the inner shell portion 300 facing the panel 3 for contact with the panel 3. The elastic member 312 extends within the inner shell portion 300 in a direction parallel to the rotation axis R of the rotating unit 10. One end of the elastic member 312 contacts the outer shell 100, and the other end contacts the conductive sheet 311. When no pressing operation is performed, there is a gap between the inner shell portion 300 and the panel 3, and correspondingly, there is also a gap between the conductive sheet 311 and the panel 3, thereby preventing the conductive sheet 311 from contacting the panel 3. When the knob 1 is pressed down, the limiting buckle 140 disengages from the limiting groove 410 and abuts against the lower end face 422, and the conductive sheet 311 contacts the panel 3 and generates an electrical signal.

[0062] This utility model embodiment also provides a stove, which includes a knob 1 as described above, and a touch screen 2, with the knob 1 mounted on the touch screen 2.

[0063] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
