Description

Technical Field

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

[0002] With technological advancements, touchscreens are increasingly being used in kitchen appliances, making these products more intelligent and convenient to use. Consumers are also becoming accustomed to the convenience brought by intelligent technology. Many kitchen appliances combine touchscreens and knobs, but communication (interaction) between the knobs and touchscreens often requires wires.

[0003] When the knob and touchscreen are not connected by wires, electrical conduction can be achieved by the knob contacting the touchscreen. However, due to factors such as structural component assembly and dimensional chain, the distance between the conductive part of the knob that contacts the touchscreen and the glass panel is not consistent, which affects the touch effect. Utility Model Content

[0004] 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.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] 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;

[0007] The rotating unit includes an outer shell and an inner shell. The outer shell is made of a conductive material, and the inner shell is disposed inside the outer shell and connected to the outer shell. The inner shell is located at the radial end region of the outer shell.

[0008] The rotating unit further includes a conductive sheet and a first elastic element. The first elastic element is made of a conductive material. The conductive sheet is attached to the inner shell portion and arranged close to the panel. The first elastic element extends within the inner shell portion along a direction parallel to the rotation axis of the rotating unit. One end of the first elastic element contacts the outer shell, and the other end contacts the conductive sheet.

[0009] In this design, the outer shell, the first elastic element, and the conductive sheet serve as part of a conductive path. When the user operates the knob and the conductive sheet contacts the panel, a conductive path is formed to trigger the cooktop panel. The conductive sheet is attached to the inner shell and can move up and down under the action of the first elastic element. This ensures the conductive sheet always has a downward tendency, allowing it to adhere to the cooktop panel and improve the touch experience.

[0010] Preferably, the outer shell and inner shell portions are movable relative to the fixed unit in the direction of the rotation axis of the rotating unit;

[0011] The inner shell portion has a first distance between the plane of the surface facing the panel and the plane of the surface where the fixing unit is connected to the panel, and in the direction of the rotation axis of the rotating unit.

[0012] In this solution, when the user operates the knob, they can first press down the rotating unit and then rotate it.

[0013] Preferably, the conductive sheet has a second distance between the surface of the panel facing the panel and the surface of the panel for mounting the knob, and in the direction of the rotation axis of the rotating unit, the second distance being smaller than the first distance.

[0014] In this design, when the user is not pressing down, there is a gap between the conductive sheet and the panel, and the conductive sheet does not contact the panel. When the user presses down, the conductive sheet contacts the panel, forming an electrical connection.

[0015] Preferably, the inner shell portion has a bottom wall on the side near the panel, and the bottom wall has a through hole; the conductive sheet includes a sheet body and a hanging part, the hanging part is connected to the sheet body, the sheet body is located below the bottom wall, and the hanging part passes through the through hole and is hung on the upper surface of the bottom wall.

[0016] In this design, the sheet body is attached to the bottom wall via a mounting part, and the sheet body can contact the panel to form electrical conductivity.

[0017] Preferably, the sheet body has a disc-shaped structure, one end of the hooking part is connected to the edge of the sheet body, and the other end of the hooking part is provided with a hooking protrusion, which is used to contact the upper surface of the bottom wall.

[0018] Preferably, the hanging part is provided on both opposite sides of the sheet body.

[0019] Preferably, the first elastic element is a spring, the inner shell portion includes an inner shell and a base, the inner shell is fixedly connected to the outer shell, and the base is connected to the inner shell by a snap-fit ​​method; the inner shell and the base have a channel for accommodating the first elastic element.

[0020] In this design, the channel can accommodate the first elastic element, allowing the force of the first elastic element to be applied in the direction of the rotation axis, so that the conductive sheet always has a downward-facing area.

[0021] Preferably, the inner shell and the base are both located within the fixing unit, and a space is formed between the inner shell, the base and the fixing unit; the channel is located within the space.

[0022] Preferably, the rotating unit further includes a push rod portion, which is disposed inside the housing and connected to the housing. The push rod portion is located in the central region of the housing, and the inner housing portion is arranged around the push rod portion. The push rod portion has a conductive material for forming a conductive path with the housing and the panel.

[0023] In this design, the outer shell and top rod portion serve as part of a conductive path, while the conductive sheet, the first elastic element, and the outer shell portion 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 sheet. This allows the cooktop panel to collect signals at the center and radial end areas of the knob, respectively, enabling the knob's rotation angle to 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.

[0024] Preferably, the fixing unit includes a bracket and a fastener, and the bracket is fixedly connected to the panel by the fastener;

[0025] A portion of the bracket extends into the housing, and a limiting structure exists between the bracket and the housing. The limiting structure restricts the rotation of the housing relative to the bracket. The limiting structure includes a limiting groove and a limiting buckle, with one of the limiting groove and the limiting buckle disposed on the bracket and the other disposed on the housing.

[0026] The outer casing is movable relative to the bracket in the direction of the rotation axis of the rotating unit, so that the limiting buckle can disengage from the limiting groove.

[0027] In this design, a limiting structure restricts the rotation of the outer casing relative to the support, thereby limiting the rotation of the rotating unit relative to the fixed unit. This ensures that after the outer casing pushes the rotating unit down, the rotating unit can rotate relative to the fixed unit, preventing accidental operation of the knob.

[0028] A cooktop includes a knob as described above, and the cooktop includes a touchscreen, the knob being mounted on the touchscreen.

[0029] The significant advantages of this invention are as follows: the outer shell, the first elastic element, and the conductive sheet can function as part of a conductive path. When the user operates the knob and the conductive sheet contacts the panel, a conductive path is formed to trigger the cooktop panel. The conductive sheet is attached to the inner shell and can move up and down under the action of the first elastic element. This ensures the conductive sheet always has a downward tendency, allowing it to adhere to the cooktop panel and improve the touch experience. Attached Figure Description

Detailed Implementation

[0040] 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.

[0041] 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.

[0042] like Figure 2 and Figure 3 As 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.

[0043] The rotating unit 10 includes a housing 100 and an inner housing portion 300. The housing 100 is made of a conductive material, and the inner housing portion 300 is disposed inside the housing 100 and connected to the housing 100. The inner housing portion 300 is located at the radial end region of the housing 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, and the inner shell portion 300 is disposed within the internal space of the outer shell 100. When the outer shell 100 is rotated by the user, the inner shell portion 300 can rotate with the outer shell 100. Figure 6 As shown, the fixing unit 20 is also located inside the outer casing 100.

[0044] like Figures 4-7 As shown, the rotating unit 10 also includes a conductive sheet 311 and a first elastic element 312. The first elastic element 312 is made of a conductive material. The conductive sheet 311 is attached to the inner shell portion 300 and arranged close to the panel 3. The first elastic element 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 first elastic element 312 contacts the outer shell 100, and the other end contacts the conductive sheet 311. The outer shell 100, the first elastic element 312, and the conductive sheet 311 can form part of a conductive path. When the user operates the knob 1 and the conductive sheet 311 contacts the panel 3, a conductive path can be formed to trigger the stove panel 3. The conductive sheet 311 is attached to the inner shell portion 300 and can move up and down under the action of the first elastic element 312. Thus, the conductive sheet 311 always has a downward tendency, allowing it to adhere to the stove panel 3 and improve the touch effect.

[0045] In a specific implementation, the conductive sheet 311 is a metal sheet, and the first elastic element 312 can be a component capable of providing axial force, preferably a spring. The conductive sheet 311 is attached to the inner shell portion 300, so that the conductive sheet 311 has a certain degree of mobility relative to the inner shell portion 300, and under the action of the first elastic element 312, the conductive sheet 311 is oriented downward, that is, towards the panel 3.

[0046] As a specific structural form of the conductive sheet 311, and a specific connection method between the conductive sheet 311 and the inner shell 300, such as Figures 4-7 As shown, the inner shell portion 300 has a bottom wall 333 on the side near the panel 3, and the bottom wall 333 has a through hole 332; the conductive sheet 311 includes a sheet body 3111 and a mounting portion 3112. The mounting portion 3112 is connected to the sheet body 3111. The sheet body 3111 is located below the bottom wall 333. The mounting portion 3112 passes through the through hole 332 and is mounted on the upper surface of the bottom wall 333. The sheet body 3111 is mounted on the bottom wall 333 through the mounting portion 3112, and the sheet body 3111 can contact the panel 3 to form electrical conductivity.

[0047] Specifically, such as Figure 4 As shown, the sheet body 3111 has a disc-shaped structure. One end of the hooking part 3112 is connected to the edge of the sheet body 3111, and the other end of the hooking part 3112 is provided with a hooking protrusion 3113. The hooking protrusion 3113 is used to contact the upper surface of the bottom wall 333.

[0048] Furthermore, the aforementioned disk-shaped structure refers to the planar form of the sheet body 3111, which is basically disk-shaped, approximating a disk shape. In addition, in specific implementations, the sheet body 3111 can also be other suitable shapes, such as polygons, ellipses, etc. The hook-and-hold part 3112 is arranged at the edge of the sheet body 3111 and can have a contour shape that is basically consistent with the edge, such as... Figure 4 As shown, the hook-on portion 3112 has an arc-shaped sheet structure. The hook-on protrusion 3113 is located on the inner surface of the upper end of the hook-on portion 3112, and this protrusion 3113 can be constrained by the upper surface of the bottom wall 333. Under the action of the first elastic member 312, as... Figure 7 As shown, the mounting protrusion 3113 abuts against the upper surface of the bottom wall 333. Furthermore, it should be noted that... Figure 7 The image shows the normal position of the sheet body 3111 under the combined action of the hook part 3112 and the first elastic member 312. Figure 6 This is a schematic representation of the sheet body 3111 lying flat on the lower surface of the bottom wall 333, to illustrate the sheet-like structural form of the sheet body 3111.

[0049] like Figure 4 As shown, in a preferred embodiment, mounting portions 3112 are provided on both opposite sides of the sheet body 3111. For example... Figure 7 As shown, the sheet body 3111 is attached to the bottom wall 333 by the hanging parts 3112 on both sides, and the first elastic member 312 acts on the sheet body 3111 at the center position between the two hanging parts 3112.

[0050] Furthermore, such as Figure 5 As shown, the upper surface of the bottom wall 333 has a cylindrical structure extending upward toward the outer casing 100. Inside the cylindrical structure is a portion of a channel 301 for accommodating the spring. The aforementioned through holes 332 are symmetrically arranged on both sides of the cylindrical structure. The through holes 332 have an arc-shaped profile that is substantially consistent with the hook-on portion 3112.

[0051] In the above embodiments, the structural form and arrangement of the conductive sheet 311 and the first elastic member 312 are provided. For the conductive sheet 311 and the first elastic member 312, whether the knob 1 can be pressed down or not, the above structural form ensures that the sheet body 3111 is in full contact with the panel 3, thereby improving the detection effect. When the knob 1 is not pressed down, the sheet body 3111 remains in contact with the panel 3. For the knob 1 with a pressing operation, further explanation will follow.

[0052] The outer shell 100 and the inner shell portion 300 are movable relative to the fixed unit 20 in the direction of the rotation axis R of the rotating unit 10; the plane on which the inner shell portion 300 faces the panel 3 and the plane on which the fixed unit 20 connects to the panel 3 are spaced apart in the direction of the rotation axis R of the rotating unit 10. When the user operates the knob 1, the rotating unit 10 can be pressed down first and then rotated.

[0053] Specifically, such as Figure 7 As shown, there is a first gap between the lower surface of the bottom wall 333 and the lower surface of the fixing unit 20, that is, there is a first gap between the lower surface of the bottom wall 333 and the upper surface of the panel 3, so that the inner shell part 300 can move in the vertical direction relative to the panel 3, leaving a corresponding operating space.

[0054] Furthermore, such as Figure 7 As shown, the conductive sheet 311 has a gap between its surface facing the panel 3, the surface of the panel 3 used to mount the knob 1, and the rotation axis R of the rotating unit 10. When the user does not press down, there is a gap between the conductive sheet 311 and the panel 3, and the conductive sheet 311 is not in contact with the panel 3. When the user presses down, the conductive sheet 311 comes into contact with the panel 3, forming an electrical connection.

[0055] Specifically, there is a second gap between the lower surface of the sheet body 3111 and the lower surface of the fixing unit 20, that is, there is a second gap between the lower surface of the sheet body 3111 and the upper surface of the panel 3, which is smaller than the first gap. During the pressing operation, the lower surface of the sheet body 3111 will first contact the upper surface of the panel 3. After further pressing, the lower surface of the bottom wall 333 will contact the upper surface of the panel 3. During this process, since the first elastic member 312 can be compressed, the sheet body 3111 can always be in contact with the panel 3 without affecting the further pressing operation.

[0056] As a specific implementation of the rotating unit 10 and the fixing unit 20, such as Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown in the figures, the implementation of these embodiments will be further described below in conjunction with the accompanying drawings.

[0057] like Figure 2 , Figure 3 and Figure 6As shown, the inner shell portion 300 includes an inner shell 320 and a base 330. The inner shell 320 is fixedly connected to the outer shell 100, and the base 330 is connected to the inner shell 320 by a snap-fit ​​connection. The inner shell 320 and the base 330 have a channel 301 for accommodating a first elastic member 312. The channel 301 allows the first elastic member 312 to be accommodated, enabling the force of the first elastic member 312 to be applied in the direction of the rotation axis R, so that the conductive sheet 311 always has a downward-facing area.

[0058] like Figure 6 and Figure 7 As shown, the bottom wall 333 is the lower wall of the base 330. The upper surface of the base 330 has a cylindrical structure with a through hole, which is part of the channel 301. At the corresponding position on the lower surface of the inner shell 320, there is also a cylindrical structure with a countersunk hole, which is another part of the channel 301.

[0059] like Figure 2 and Figure 3 As shown, the inner surface of the outer shell 100 facing the inner shell 320 has a concave structure, and the inner shell 320 correspondingly has an annular flange connected to the concave structure. A mating groove 130 and a mating block 321 are also provided at the connection between the outer shell 100 and the inner shell 320. The mating block 321 is disposed on the annular flange of the inner shell 320 and extends in the radial direction, so that the inner shell 320 can rotate when the outer shell 100 rotates.

[0060] like Figure 2 , Figure 3 and Figure 8 As shown, the inner shell 320 has a second slot 322, and the base 330 has a second buckle 331, which engages with the second slot 322. In the circumferential direction, there are multiple second slots 322 and second buckles 331, each corresponding to the other. Figure 6 and Figure 8 As shown, the inner shell 320 and the base 330 are also interlocked. When the knob 1 is pressed down, the outer shell 100 drives the inner shell 320, and the inner shell 320 drives the base 330 to move downward, so that the conductive sheet 311 can contact the panel 3.

[0061] like Figure 2 , Figure 3 , Figure 6 and Figure 8As shown, the rotating unit 10 also includes a push rod portion 200, which is disposed inside and connected to the outer casing 100. The push rod portion 200 is located in the central region of the outer casing 100, and the inner casing portion 300 is arranged around the push rod portion 200. The push rod portion 200 has a conductive material for forming a conductive path with the outer casing 100 and the panel 3. The outer casing 100 and the push rod portion 200 can be part of a conductive path, and the conductive sheet 311 of the inner casing portion 300, the first elastic member 312, and the outer casing 100 can be 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 push rod portion 200 and the conductive sheet 311 through user operation, and the cooktop panel 3 can collect signals at the central region and the radial end region of the knob 1, respectively. The rotation angle of the knob 1 can be obtained from the signals at these two locations. Furthermore, the knob 1 is mounted on the cooktop panel 3 via the fixing unit 20. By forming two conductive paths, there is no need to drill holes to lay wires, thereby improving the ease of use of the knob 1.

[0062] 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 sheet 311 and a first elastic member 312. The first elastic member 312 contacts the outer shell 100. The conductive sheet 311 is located on 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, allowing it to form a conductive path with the outer shell 100. The inner shell portion 300, except for the conductive sheet 311 and the first elastic member 312, is made of a non-conductive material, so that the inner shell portion 300 forms a conductive path with the outer shell 100 at the locations where the conductive sheet 311 and the first elastic member 312 are present. Figure 6 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.

[0063] Furthermore, such as Figure 6 As shown in the figure, the push rod portion 200 has an elastic compression capacity, ensuring that it remains in contact with the panel 3 at all times. After being pressed down, the conductive sheet 311 of the inner shell portion 300 contacts the panel 3. Furthermore, the contact between the push rod portion 200 and the panel 3 also allows it to serve as a support for the rotating unit 10, preventing the inner shell portion 300 from contacting the panel 3 when not being pressed down. In other embodiments, other structures can be provided to support the rotating unit 10, allowing the push rod portion 200 and the inner shell portion 300 to contact the panel 3 again after the pressing operation.

[0064] As a specific embodiment where the push rod portion 200 has an elastic compression amount, such as Figure 2, Figure 3 , Figure 6 and Figure 8 As shown, the push rod portion 200 includes a push rod 210 and a second elastic member 220. The inner surface of the housing 100 is provided with a receiving groove 110. The push rod 210 extends into the receiving groove 110. The second elastic member 220 abuts against the receiving groove 110 and the push rod 210 and applies a force along the rotation axis R of the rotating unit 10.

[0065] like Figure 6 and Figure 8 As shown, the portion of the push rod 210 that extends into the receiving groove 110 has a stepped structure. The second elastic element 220 is a spring, with one end abutting against the wall of the receiving groove 110 and the other end sleeved on the stepped structure. This allows the push rod 210 to move along the axial direction of the spring, and the spring to apply pressure to the housing 100 and the push rod 210. Preferably, the surface of the push rod 210 facing the panel 3 is arc-shaped, and the rotation axis R of the rotating unit 10 passes through the center of this arc-shaped push rod 210.

[0066] like Figure 8 As shown, the push rod 210 is connected to the side wall of the receiving groove 110 by a snap-fit ​​connection. Specifically, as... Figure 8 As shown, the side wall of the receiving groove 110 is provided with a first slot 111, and the side wall of the push rod 210 is provided with a first buckle 211, which is engaged with the first slot 111. As an alternative embodiment, the first slot 111 can also be provided on the outer side wall of the push rod 210, and the first buckle 211 can be provided on the inner side wall of the receiving groove 110.

[0067] like Figure 3 and Figure 8 As shown, the fixing unit 20 includes a bracket 400 and a fastener 500, with the bracket 400 fixedly connected to the panel 3 via the fastener 500. Specifically, the bracket 400 can be fixed to the panel 3 by screws; in other embodiments, it can also be fixed to the panel 3 by other means such as adhesive.

[0068] like Figure 3 and Figure 8As shown, a portion of the bracket 400 extends into the outer casing 100. A limiting structure exists between the bracket 400 and the outer casing 100 to restrict the rotation of the outer casing 100 relative to the bracket 400. The limiting structure includes a limiting groove 410 and a limiting buckle 140, one of which is located on the bracket 400, and the other on the outer casing 100. The outer casing 100 is movable relative to the bracket 400 in the direction of the rotation axis R of the rotating unit 10, allowing the limiting buckle 140 to disengage from the limiting groove 410. The limiting structure restricts the rotation of the outer casing 100 relative to the bracket 400, thereby restricting the rotation of the rotating unit 10 relative to the fixed unit 20. This ensures that after the outer casing 100 pushes down the rotating unit 10, the rotating unit 10 can rotate relative to the fixed unit 20, preventing accidental operation of the knob 1.

[0069] like Figure 3 and Figure 8 As shown, the outer wall of the bracket 400 is provided with a limiting groove 410, which extends in a direction parallel to the rotation axis R of the rotating unit 10 and passes through the end of the bracket 400 facing the panel 3; the limiting buckle 140 is provided on the edge of the side wall of the housing 100 and extends into the interior of the housing 100. Further, as Figure 8 As shown, the limiting buckle 140 extends into the limiting groove 410, and the side wall of the limiting groove 410 in the circumferential direction can restrict the limiting buckle 140. When the housing 100 is pressed down, the limiting buckle 140 moves downward and leaves the limiting groove 410, so that the housing 100 can rotate relative to the bracket 400.

[0070] like Figure 6 As shown, the inner shell 320 and the base 330 are both located within the fixing unit 20, and a space is formed between the inner shell 320, the base 330 and the fixing unit 20; the channel 301 is located within the space.

[0071] This embodiment also provides a cooktop, which includes a knob 1 as described above, and a touch screen 2, with the knob 1 mounted on the touch screen 2.

[0072] 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.
