Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils, and in particular to a stove. Background Technology

[0002] Lateral shift of the glass panel in a gas stove can cause the drip tray to scratch the glass panel, resulting in minor product defects. Currently, in the production and transportation of gas stoves, the main anti-lateral shift solutions between the glass panel and the chassis include double-sided tape fixing (adhesive is applied between the chassis and the glass panel to limit relative displacement through viscous friction), screw pressing structure (the drip tray and positioning ring are locked together by burner screws, and the glass panel is horizontally and vertically limited by a waterproof ring and installation platform), adhesive auxiliary tooling (adhesive is used to fill the gap between the glass panel and the chassis, forming a cured layer after curing), and limiting the chassis skirt by attaching glass panel gaskets to prevent lateral shift of the glass panel. However, most existing technologies rely on adhesives and do not introduce independent mechanical limiting structures, or the limiting structures do not achieve the desired limiting effect.

[0003] This results in the following defects:

[0004] 1. Difficult to repair: When a small amount of double-sided tape is used, the glass panel will shift to the side. When a large amount of double-sided tape is used, it is difficult for service technicians to open the glass panel when repairing the stove. The repairman needs to forcibly remove the glass panel, which can easily cause secondary damage.

[0005] 2. Poor versatility: Existing anti-lateral displacement solutions are ineffective. A solution may be effective in preventing lateral displacement for a certain product, but lateral displacement still exists for other products, causing the liquid tray to scratch the glass panel.

[0006] 3. High cost: Most existing solutions use glass panel spacers and double-sided tape to limit the glass panel, and the glass panel spacers have a large area and low raw material utilization efficiency, resulting in cost waste. Utility Model Content

[0007] The technical problem to be solved by this invention is how to prevent the cooktop panel from shifting laterally relative to the chassis, and a cooktop is provided for this purpose.

[0008] The present invention solves the above-mentioned technical problems through the following technical solution:

[0009] A cooktop includes: a control panel, a base, and a limiting structure;

[0010] The limiting structure includes mutually adaptable limiting protrusions and limiting holes, with the limiting protrusions inserted into the limiting holes.

[0011] The limiting protrusion is disposed on the lower surface of the panel, and the limiting hole is disposed on the skirt of the chassis.

[0012] In this design, the stove uses mutually compatible limiting protrusions and limiting holes to constrain the chassis in each degree of freedom relative to the plane where the glass panel is located, thus fixing the chassis to the plane where the glass panel is located due to the addition of the limiting structure.

[0013] Preferably, the limiting protrusion includes an insertion portion that is inserted into the limiting hole, and the insertion portion tapers downward.

[0014] In this design, the insertion part of the limiting protrusion tapers downwards, which facilitates the insertion of the insertion part into the limiting hole and allows for good locking without leaving any gaps, ensuring accurate positioning. Furthermore, the limiting protrusion has a certain taper, which makes the engagement between the insertion part and the limiting hole tighter as the chassis and panel are tightened together, thereby fixing the lateral relative position between the panel and the chassis.

[0015] Preferably, the side of the insertion portion is tilted at an angle of 1°-10° relative to the vertical direction.

[0016] Preferably, the lower surface of the insertion part has a rounded corner structure.

[0017] In this design, the rounded corners of the head of the insertion part facilitate its insertion into the limiting hole.

[0018] Preferably, the edge of the panel is provided with a limiting strip, and the height of the limiting protrusion is lower than the height of the limiting strip extending beyond the lower surface of the panel.

[0019] In this design, the height of the limiting protrusion is lower than the height of the limiting strip extending beyond the lower surface of the panel, facilitating the transport of the stove and not affecting the countertop clearance. When the stove is installed on the kitchen countertop, the countertop will only contact the limiting strip, not the limiting protrusion, thus preventing the installation from affecting the limiting effect of the limiting structure.

[0020] Preferably, the number of the limiting structures is four and they are respectively arranged at the four corners of the panel. The limiting protrusion includes an insertion part that is inserted into the limiting hole, and the insertion part is frustoconical.

[0021] In this design, there are four limiting structures, and the lines connecting the four limiting structures form a rectangle, so that each limiting structure can be subjected to force evenly.

[0022] Preferably, the number of limiting structures is three, and the limiting protrusion includes an insertion part that is inserted into the limiting hole. The insertion part is formed into a triangle, and the three limiting structures are arranged such that the line connecting the positions of the three limiting structures forms an isosceles triangle.

[0023] In this design, there are three limiting structures. The lines connecting the three limiting structures form an isosceles triangle, creating a stable "iron triangle" structure that ensures that each limiting structure is subjected to force evenly. Each limiting structure has three contact surfaces.

[0024] Preferably, the panel includes two long sides and two short sides, the two long sides being a first long side and a second long side, the second long side being located near the knob of the stove on the panel;

[0025] One of the three limiting structures is positioned at the midpoint of the second long side along the length of the stove, and the other two limiting structures are respectively positioned at the two corners of the stove near the first long side.

[0026] Preferably, the panel includes two long sides and two short sides, the two long sides being a first long side and a second long side, the first long side being close to the position where the knob of the stove is located on the panel;

[0027] The skirt edge of the chassis near the first long side is called the first skirt edge, and the first skirt edge and the panel are fixed together by adhesive.

[0028] The limiting protrusion includes an insertion part that is inserted into the limiting hole. The insertion part is frustum-shaped. There are two limiting structures, which are respectively located at the two corners of the stove near the second long side.

[0029] In this solution, although double-sided tape is also used on one side of the panel, since the double-sided tape is only used on one side of the panel, when the panel and chassis need to be separated for maintenance, the panel and chassis can be easily separated from the other side of the panel, without the panel and chassis being difficult to separate due to the use of double-sided tape in multiple places.

[0030] Preferably, the first skirt and the panel are fixed together with double-sided adhesive.

[0031] Preferably, the stove includes two burners.

[0032] Preferably, the size of the root of the insertion part is larger than the size of the limiting hole.

[0033] In this design, the size of the root of the insertion part is larger than the size of the limiting hole, which allows the insertion part and the limiting hole to fit tightly without leaving any gaps, ensuring accurate positioning and avoiding inertial impact caused by gaps during violent impacts.

[0034] The positive and progressive effects of this utility model are as follows: the stove, through the mutually adaptable limiting protrusions and limiting holes, constrains the various degrees of freedom of the chassis relative to the plane where the glass panel is located, so that the chassis is fixed on the plane where the glass panel is located due to the addition of the limiting structure.

Detailed Implementation

[0041] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0042] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with an embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0043] Example 1

[0044] This embodiment provides a stove 100, one example of which is a gas stove using bottled or piped natural gas. The stove 100 can be a multi-burner (burner) stove or a single-burner stove; this embodiment uses a dual-burner stove as an example. The stove 100 includes a panel 110, a base 120 connected below the panel 110, a burner (not shown) mounted on the base 120, and a pot support (not shown) surrounding the burner. The base 120 of the stove 100 may contain an ejector system connected to the burner (in some embodiments, the ejector system can be defined as part of the burner) and a control system for controlling the burner's ignition, timing, flame size, etc. In this embodiment, the panel 110 is a glass panel. However, this invention is not limited to this; the structure of this invention can also be applied to stainless steel panels, etc.

[0045] The cooktop 100 can be a smart appliance equipped with a smart voice control module or a smart gesture sensing control module. The smart voice control module includes a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, which are then parsed by the voice parsing module. Based on the parsed commands, the controller controls the cooktop 100's gas intake valve, ignition switch, and other functions to perform corresponding operations, thereby achieving intelligent control of the cooktop 100's firepower and ignition / extinguishing mechanism, improving the user experience of using this smart appliance. The smart gesture sensing control module includes a controller, a motion detection module, and a motion parsing module. The motion detection module detects the user's gestures, which are then parsed by the motion parsing module. Based on the parsed commands, the controller controls the cooktop 100's gas intake valve, ignition switch, and other functions to perform corresponding operations, thereby achieving intelligent control of the cooktop 100's firepower and ignition / extinguishing mechanism, improving the user experience of using this smart appliance.

[0046] The cooktop 100 includes: a panel 110, a chassis 120, and a limiting structure 130.

[0047] The limiting structure 130 includes mutually compatible limiting protrusions 131 and limiting holes 132. The limiting protrusions 131 are inserted into the limiting holes 132. The limiting protrusions 131 are located on the lower surface of the panel 110, and the limiting holes 132 are located on the skirt 121 of the chassis 120.

[0048] The cooktop 100 uses mutually compatible limiting protrusions 131 and limiting holes 132 to constrain the chassis 120 in each degree of freedom relative to the plane where the glass panel 110 is located, so that the chassis 120 is fixed on the plane where the glass panel 110 is located due to the addition of the limiting structure 130.

[0049] It should be noted that the limiting structure 130 of this utility model is only used to limit the relative horizontal displacement between the panel 110 and the chassis 120, and does not undertake the mutual fixation between the chassis 120 and the panel 110 or the limitation of the relative vertical displacement between the chassis 120 and the panel 110. The mutual fixation between the chassis 120 and the panel 110 can be achieved by existing fixing methods, such as using the mutual fixation between the liquid-holding tray and the chassis 120, which will not be elaborated here.

[0050] like Figure 3 As shown, the limiting protrusion 131 includes an insertion portion 1312 that inserts into the limiting hole 132. The insertion portion 1312 is frustoconical and tapers downwards. The limiting protrusion 131 also includes a base 1311, with the insertion portion 1312 connected to the lower part of the base 1311. The base 1311 is used to fix it to the lower surface of the panel 110. The fixing method between the limiting protrusion 131, i.e., the base 1311, and the panel 110 is usually adhesive. Alternatively, it can also be fixed in other ways, such as the limiting protrusion 131 being integrally formed onto the lower surface of the panel 110. The shape of the base 1311 is preferably the same as the shape of the insertion portion 1312, but it can also be different as needed.

[0051] The insertion portion 1312 of the limiting protrusion 131 tapers downwards, which facilitates the insertion portion 1312 into the limiting hole 132 and allows for good locking without leaving any gaps, ensuring accurate positioning. Furthermore, the limiting protrusion 131 has a certain taper, and as the chassis 120 and the panel 110 are tightened together, the engagement between the insertion portion 1312 and the limiting hole 132 becomes tighter, thereby fixing the lateral relative position between the panel 110 and the chassis 120.

[0052] The root dimension of the insertion part 1312 is larger than the dimension of the limiting hole 132. This larger root dimension ensures a tight fit between the insertion part 1312 and the limiting hole 132, eliminating gaps and ensuring accurate positioning. This also prevents inertial impacts caused by gaps during violent impacts. Figure 3 As shown, the diameter B of the root of the insertion part 1312 is greater than the diameter A1 of the limiting hole 132, while the diameter A1 of the head of the insertion part 1312 is smaller than the diameter B of the root of the insertion part 1312.

[0053] The side of the insertion part 1312 is inclined at an angle of 1°-10° relative to the vertical direction. Figure 3 The diagram illustrates the inclination angle α of the side of the insertion part 1312 relative to the horizontal direction, where 91° < α < 100°. Preferably, the lower surface edge of the insertion part 1312 has a rounded corner structure. The rounded corner structure of the head of the insertion part 1312 facilitates its insertion into the limiting hole 132.

[0054] A limiting strip 115 is provided on the edge of the panel 110, and the height of the limiting protrusion 131 is lower than the height of the limiting strip 115 extending beyond the lower surface of the panel 110. The limiting strip 115 may be a silicone strip adhered to the lower edge of the panel 110 or a protective sleeve structure covering the edge of the panel 110, etc.

[0055] The height of the limiting protrusion 131 is lower than the height of the limiting strip 115 extending beyond the lower surface of the panel 110, facilitating the transportation of the cooktop 100 without affecting the countertop clearance. When the cooktop 100 is installed on the kitchen countertop, the countertop will only contact the limiting strip 115 and not the limiting protrusion 131, avoiding any impact on the limiting effect of the limiting structure 130 during installation.

[0056] Four limiting structures 130 are provided, each positioned at one of the four corners of the corresponding panel 110. The insertion portion 1312 is frustum-shaped. In other embodiments, the cross-sectional shape of the insertion portion 1312 may not be circular, but may be square, rhomboid, or similar. Considering that a circular shape facilitates the insertion of the insertion portion 1312 and its manufacturing, a circular shape is preferred. The interior of the insertion portion 1312 may be solid or hollow, and may be reinforced with ribs to improve its support strength.

[0057] In this embodiment, there are four limiting structures 130. The lines connecting the four limiting structures 130 form a rectangle, so that each limiting structure 130 can be subjected to force evenly.

[0058] The stove 100 in this embodiment underwent a drop test to verify its effectiveness, and the drop test met the requirements of GB / T4857.5.

[0059] In the test, a standard double-burner stove 100 was placed in the packaging and packaged in a conventional manner. The packaged sample was then tilted at 45° and dropped from a predetermined height.

[0060] The drop test used a comparative example in which the skirt 121 of the chassis 120 and the panel 110 were only bonded together with double-sided tape. The results observed in the test were: there was relative displacement between the glass panel 110 and the drip tray at the moment of drop; after the drop, the state of the foam (used to cushion the stove in the packaging) was observed, the compression distance of the glass panel 110 exceeded 10 mm, and the scratch length of the glass panel 110 after disassembly was 10 mm.

[0061] The observation results of the stove 100 in this embodiment are as follows: after the glass panel 110 is removed, under strong light, the glass panel 110 only has local scratches on one side of the burner of the stove 100, and the scratch length is less than 3 mm.

[0062] Example 2

[0063] like Figure 4As shown, the stove 100 in this embodiment is largely the same as the stove 100 in embodiment 1, except that:

[0064] The number of limiting structures 130 is three and they are arranged in a triangle. The lines connecting the positions of the three limiting structures 130 form an isosceles triangle.

[0065] In this design, there are three limiting structures 130. The lines connecting the three limiting structures 130 form an isosceles triangle, creating a stable "iron triangle" structure that ensures that each limiting structure 130 is subjected to uniform force. Each limiting structure 130 has three contact surfaces.

[0066] The panel 110 includes two long sides and two short sides. The two long sides are a first long side 111 and a second long side 112, respectively. The first long side 111 is located near the knob of the stove 100 on the panel 110.

[0067] One of the three limiting structures 130 is positioned at the midpoint of the second long side 112 along the length of the stove 100, and the other two are positioned at the two corners of the stove 100 closest to the first long side 111. The skirt 121 of the chassis 120 at the position corresponding to the second long side 112 is relatively wide, making it easier to install the limiting structure 130.

[0068] The insertion portion 1312 of the limiting protrusion 131 in this embodiment also has a taper, that is, the same tapered structure as in Embodiment 1, and the tilt angle of its side is also consistent with that in Embodiment 1.

[0069] Example 3

[0070] like Figure 5 As shown, the stove 100 in this embodiment is largely the same as the stove 100 in embodiment 1, except that:

[0071] The panel 110 includes two long sides and two short sides. The two long sides are a first long side 111 and a second long side 112, respectively. The first long side 111 is located near the knob of the stove 100 on the panel 110.

[0072] The skirt 121 of the chassis 120 near the first long side 111 is called the first skirt 1211, and the first skirt 1211 and the panel 110 are fixed by adhesive.

[0073] The limiting protrusion 131 includes an insertion part 1312 that inserts into the limiting hole 132. The insertion part 1312 is frustoconical. There are two limiting protrusions 131, which are respectively located at the two corners of the stove 100 near the second long side 112.

[0074] Although double-sided tape is also used on one side of panel 110, since the double-sided tape is only used on one side of panel 110, when panel 110 and chassis 120 need to be separated for maintenance, panel 110 and chassis 120 can be easily separated from the other side of panel 110, without the difficulty of separating panel 110 and chassis 120 due to the use of double-sided tape in multiple places.

[0075] The first skirt 1211 and the panel 110 are fixed together with double-sided tape. The length of the double-sided tape is preferably 550mm, which basically covers the first skirt 1211.

[0076] The stove 100 in this embodiment underwent a drop test to verify its effectiveness, and the drop test met the requirements of GB / T4857.5.

[0077] In the test, a standard double-burner stove 100 was placed in the packaging and packaged in a conventional manner. The packaged sample was then tilted at 45° and dropped from a predetermined height.

[0078] The drop test used a comparative example in which the skirt 121 of the chassis 120 and the panel 110 were only bonded together with double-sided tape. The results observed in the test were: there was relative displacement between the glass panel 110 and the liquid receiving tray at the moment of drop; the state of the foam after the drop was observed; the compression distance of the glass panel 110 exceeded 10 mm; and the scratch length of the glass panel 110 after disassembly was 10 mm.

[0079] The observation results of the stove 100 in this embodiment are as follows: after the glass panel 110 is removed, under strong light, the glass panel 110 only shows localized dense scratches around the burner of the stove 100, and the scratches are less than 3 mm in length.
