Description

[Technical Field]

[0001] This application relates to the field of cooktops, and in particular to the design of a knob assembly and a cooktop. [Background Technology]

[0002] As one of the most commonly used kitchen appliances, gas stoves currently employ knobs to adjust the gas output and thus the flame size. However, most existing gas stove knobs are simple, one-piece pressurized structures, typically mounted on a valve stem via a hole and shaft. These knobs are prone to wobbling during use, negatively impacting the stove's performance. Therefore, there is a market demand for stove knobs with effective anti-wobbling features.

[0003] Unless there is sufficient evidence to support it, the prior art described herein does not imply an admission that such prior art was known to a person skilled in the art prior to the filing date of this application. [Summary of the Invention]

[0004] One objective of this application is to provide an improved knob assembly for a cooktop, addressing at least one of the above-mentioned technical problems and / or other possible technical problems not mentioned in this application.

[0005] An embodiment of this application provides a knob assembly for a cooker, the cooker including a valve stem capable of reciprocating along an axial direction, the knob assembly being mounted on the outer axial end of the valve stem to press and rotate the valve stem, characterized in that: the knob assembly includes a valve stem connecting portion into which the valve stem can be inserted; the valve stem is formed with a mounting seat having an opening facing its outer axial end, the valve stem connecting portion being confined within the opening.

[0006] Therefore, the valve stem connection is confined within the opening, making it less prone to relative wobbling with the valve stem, which helps improve the stability of the knob assembly and the user experience.

[0007] In one or more embodiments, the mounting base is configured as a boss that protrudes radially outward along the valve stem; the opening is formed circumferentially along the valve stem on the upper surface of the boss and together with the outer wall of the valve stem forms a groove that restricts the valve stem connection.

[0008] In one or more embodiments, the bottom of the valve stem connector is provided with a connecting channel for the valve stem to be inserted; when the valve stem is inserted into the connecting channel, the valve stem connector is inserted into the groove.

[0009] In one or more embodiments, the groove and the valve stem connection are interference fit.

[0010] In one or more embodiments, the diameters of the valve stem connection and the groove gradually decrease axially from top to bottom.

[0011] In one or more embodiments, the inner wall of the connecting channel is provided with an elastic element; the elastic element is squeezed and in a compressed state after the valve stem is inserted into the connecting channel.

[0012] In one or more embodiments, the valve stem and the connecting channel have a D-shaped cross-section.

[0013] In one or more embodiments, the outer axial end of the valve stem is chamfered.

[0014] In one or more embodiments, the mounting base is integrally formed onto the valve stem.

[0015] An embodiment of this application provides a cooktop including a knob assembly as described in any of the above embodiments.

Detailed Implementation Methods

[0026] To make the purpose, solution, and beneficial effects of this application clearer, the application will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0027] This application discloses an embodiment of a knob assembly for a stove, such as... Figure 1 As shown, it includes a valve stem 1 that can reciprocate along the axial direction, and a knob assembly 2 is installed on the outer axial end of the valve stem 1 (i.e., the end that is axially away from the bottom shell of the stove) to press and rotate the valve stem 1.

[0028] Furthermore, such as Figure 1 and Figure 2 As shown, the knob assembly 2 includes a knob cover 20 and a valve stem connection portion 21. The knob cover 20 is located above and fixedly connected to the valve stem connection portion 21, which allows the valve stem 1 to be inserted. To minimize the wobble of the knob assembly 2 caused by this axial hole fit, the valve stem 1 has a mounting seat 11 with an opening facing its axially outer end. The opening should be designed to allow the knob assembly 2 to be installed on the valve stem 1 from its axially outer end. After installation, the valve stem connection portion 21 is confined within the opening of the mounting seat 11, improving the user experience when using the knob.

[0029] According to an exemplary embodiment of this application, such as Figure 2 As shown, the mounting base 11 is constructed as a boss that protrudes outward along the radial direction of the valve stem 1. The opening is formed on the upper surface of the boss along the circumference of the valve stem 1. The outer wall of the valve stem 1 and the opening together form a groove 12 that restricts the valve stem connection portion 21.

[0030] Furthermore, the bottom of the valve stem connecting portion 21 is provided with a connecting channel 22 for the valve stem 1 to be inserted; when the valve stem 1 is inserted into the connecting channel 22, the valve stem connecting portion 21 is inserted into the groove 12. Figure 1 As shown, the outer wall of the connecting channel 22 is pressed into the groove 12 in the radial direction, which can effectively prevent the knob assembly 2 from shaking in the radial direction.

[0031] Furthermore, the groove 12 and the valve stem connection 21 are interference-fitted. This further enhances the reliability of the aforementioned knob anti-shake structure.

[0032] The knob assembly 2 is typically manufactured using injection molding. To facilitate subsequent demolding, according to an exemplary embodiment of this application, the diameter of the valve stem connection portion 21 is configured to gradually decrease from top to bottom along the axial direction. To achieve a tight fit with the valve stem connection portion 21, the diameter of the groove 12 is also configured to gradually decrease from top to bottom along the axial direction.

[0033] According to an exemplary embodiment of this application, the inner wall of the connecting channel 22 is provided with an elastic element (not shown). When the valve stem 1 is inserted into the connecting channel 22, it begins to compress the elastic element, causing it to compress radially along the connecting channel 22. As a result, the valve stem 1 is subjected to a radial clamping force, further enhancing the radial anti-sway effect.

[0034] According to an exemplary embodiment of this application, such as Figure 3 and Figure 4 As shown, the cross-section of the valve stem 1 and the connecting channel 22 is D-shaped. Specifically, the inner wall surface of the connecting channel 22 that mates with the valve stem 1 is D-shaped, which ensures that there is no relative rotation between the valve stem 1 and the knob assembly 2, thereby improving the accuracy and reliability of using the knob to control the firepower.

[0035] According to an exemplary embodiment of this application, the outer axial end of the valve stem 1 is chamfered, which facilitates the smooth entry of the valve stem 1 into the connection channel 22 when the knob assembly 2 is installed.

[0036] According to an exemplary embodiment of this application, the mounting base 11 is integrally formed on the valve stem 1, which facilitates casting while improving the stability of the structure.

[0037] This application also proposes an embodiment of a cooktop, which includes the knob assembly 2 of the cooktop described above.

[0038] The components of different embodiments can be combined with each other in any feasible manner to achieve the purpose of this application.

[0039] It should be further noted that this application should not be construed as limited to the embodiments described above, but rather as covering all possible implementations determined by the claims of this application in conjunction with the content disclosed in the specification. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the scope of the technical solution of this application shall fall within the protection scope of the technical solution of this application.
