Description

TECHNICAL FIELD

[0001] The present application relates to the field of kitchen appliances, in particular to a stove. BACKGROUND

[0002] The side shift of the glass panel of the stove will cause the liquid container to scratch the glass panel, resulting in subtle defects of the product. At present, in the production and transportation of gas stoves, the anti-side shift scheme between the glass panel and the bottom plate mainly includes the double-sided adhesive fixing method (double-sided adhesive is pasted between the bottom plate and the glass panel to limit the relative displacement between the two by adhesive friction), the screw pressing structure (the liquid container is locked with the positioning ring by the burner screw, and the glass panel is limited in the horizontal and vertical directions by the waterproof ring and the mounting platform), the adhesive auxiliary tool (the gap between the glass panel and the bottom plate is filled with adhesive, and a solidified layer is formed after solidification), and the glass panel gasket is pasted to limit the skirt of the bottom plate, thereby preventing the side shift of the glass panel. However, most of the existing technologies rely on adhesive, without introducing independent mechanical limiting structure, or the limiting structure cannot achieve ideal limiting effect.

[0003] This causes the following defects:

[0004] 1. Difficult to repair: when the amount of double-sided adhesive used is small, the glass panel will shift sideways, and when the amount of double-sided adhesive used is large, it is difficult for the service technician to open the glass panel when repairing the stove. The repairman needs to violently disassemble the glass panel, which can easily cause secondary damage;

[0005] 2. Poor universality: the existing anti-side shift scheme has poor effect. The scheme may have good anti-side shift effect for a certain product, but still has side shift for other products, resulting in the problem of the liquid container scratching the glass panel;

[0006] 3. High cost: most of the existing schemes use glass panel gasket to assist double-sided adhesive to limit the glass panel, and the glass panel gasket has a large use area, which reduces the utilization efficiency of raw materials and causes waste of cost. SUMMARY

[0007] The technical problem to be solved by the present application is how to prevent the panel of the stove from shifting sideways relative to the bottom plate, and a stove is provided for this purpose.

[0008] The present application solves the above technical problems by the following technical scheme:

[0009] A stove, comprising: a panel, a bottom plate and a limiting structure;

[0010] The limiting structure comprises a limiting protrusion and a limiting hole that are adapted to each other, the limiting protrusion is inserted into the limiting hole,

[0011] The limiting protrusion is arranged on the lower surface of the panel, and the limiting hole is arranged on the skirt of the bottom plate.

[0012] In the scheme, the cooktop is constrained in each degree of freedom relative to the plane where the glass panel is located by the mutually fitted limiting protrusions and limiting holes, so that the bottom plate is fixed on the plane where the glass panel is located due to the addition of the limiting structure.

[0013] Preferably, the limiting protrusion comprises an insertion portion inserted into the limiting hole, and the insertion portion is tapered downward.

[0014] In the scheme, the insertion portion of the limiting protrusion is tapered downward, so that the insertion portion is conveniently inserted into the limiting hole, and the clamping is good without leaving a gap, so that the limiting is accurate, and the limiting protrusion has a certain taper, and as the bottom plate and the panel are tightly fastened with each other, the insertion portion and the limiting hole are more tightly engaged, so that the lateral relative position between the panel and the bottom plate is fixed.

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

[0016] Preferably, the edge of the lower surface of the insertion portion is a rounded structure.

[0017] In the scheme, the rounded structure of the head of the insertion portion can 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 beyond the lower surface of the panel.

[0019] In the scheme, the height of the limiting protrusion is lower than the height of the limiting strip beyond the lower surface of the panel, which facilitates the transportation of the cooktop, while not affecting the countertop gap. When the cooktop is installed on the countertop of the kitchen, the countertop will only contact the limiting strip, but not the limiting protrusion, so as to avoid the installation affecting the limiting effect of the limiting structure.

[0020] Preferably, the number of the limiting structures is four and is arranged at positions corresponding to the four corners of the panel, the limiting protrusion comprises an insertion portion inserted into the limiting hole, and the insertion portion is a circular truncated cone.

[0021] In the scheme, there are four limiting structures, and the connecting line of the four limiting structures forms a rectangle, so that each limiting structure can be uniformly stressed.

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

[0023] In the present scheme, there are three limiting structures, and the connecting lines of the three limiting structures form an isosceles triangle, forming a stable "iron triangle" structure, so that each limiting structure can bear 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 are a first long side and a second long side respectively, and the second long side is close to the position where the knob of the stove is arranged on the panel;

[0025] One of the three limiting structures is arranged at the position of the midpoint of the corresponding second long side in the length direction of the stove, and the other two of the three limiting structures are arranged at the positions corresponding to the two corners close to the first long side of the stove respectively.

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

[0027] The skirt edge of the bottom disc close to the first long side is a first skirt edge, and the first skirt edge and the panel are fixed by bonding;

[0028] The limiting protrusion includes an insertion part inserted into the limiting hole, the insertion part is a circular truncated cone, and the number of the limiting structures is two and is arranged at the positions corresponding to the two corners close to the second long side of the stove respectively.

[0029] In the present scheme, 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 the bottom disc are separated due to maintenance, the panel and the bottom disc can be easily separated from the other side of the panel, and the panel and the bottom disc are not difficult to separate due to the use of double-sided tape at multiple places.

[0030] Preferably, the first skirt edge and the panel are fixed by double-sided tape.

[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 the present scheme, the size of the root of the insertion part is larger than the size of the limiting hole, so that the insertion part and the limiting hole are tightly clamped without leaving gaps, the limiting is accurate, and when there is a violent impact, the inertia impact caused by the gap is avoided.

[0034] The positive progress effect of the present application is that the stove is constrained in each degree of freedom relative to the plane where the glass panel is located by the mutually matched limiting protrusions and limiting holes, so that the bottom plate is fixed on the plane where the glass panel is located due to the addition of the limiting structure.

[0043] Embodiment 1

[0044] The embodiment provides a stove 100, one example of which is a gas stove using canned natural gas or pipeline natural gas. The stove 100 can be a multi-burner stove or a single-burner stove, and the embodiment takes a double-burner stove as an example for description. The stove 100 comprises a panel 110, a bottom plate 120 connected below the panel 110, a burner (not shown) arranged on the bottom plate 120, and a pot support (not shown) arranged around the burner. The bottom plate 120 of the stove 100 can be provided with an injection system connected with the burner (in some embodiments, the injection system can be defined as a part of the burner) and a control system for controlling ignition, timing, flame size and the like of the burner. The panel 110 of the embodiment is a glass panel. However, the present application is not limited thereto, and the structure of the present application can also be applied to a stainless steel panel and the like.

[0045] The stove 100 can be a smart appliance and be mounted on a smart voice control module or a smart gesture sensing control module and the like. The smart voice control module comprises a controller, a voice receiving module and a voice analysis module. The voice receiving module receives instructions of a user, and the voice analysis module analyzes the instructions. According to the analyzed instructions, the controller controls the air inlet valve, the ignition switch and the like of the stove 100 to perform corresponding operations, so as to realize intelligent control of the firepower and ignition and extinguishing of the stove 100, and improve the use experience of the user using the smart appliance. The smart gesture sensing control module comprises a controller, a motion detection module and a motion analysis module. The motion detection module detects the gesture of the user, and the motion analysis module analyzes the instructions. According to the analyzed instructions, the controller controls the air inlet valve, the ignition switch and the like of the stove 100 to perform corresponding operations, so as to realize intelligent control of the firepower and ignition and extinguishing of the stove 100, and improve the use experience of the user using the smart appliance.

[0046] The stove 100 comprises the panel 110, the bottom plate 120 and a limiting structure 130.

[0047] The limiting structure 130 comprises a limiting protrusion 131 and a limiting hole 132 which are matched with each other. The limiting protrusion 131 is inserted into the limiting hole 132. The limiting protrusion 131 is arranged on the lower surface of the panel 110, and the limiting hole 132 is arranged on the skirt 121 of the bottom plate 120.

[0048] The limiting protrusion 131 and the limiting hole 132 of the stove 100 are matched with each other, so that the bottom plate 120 is constrained in each degree of freedom on the plane where the glass panel 110 is located. Therefore, the bottom plate 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 is only used to limit the relative horizontal displacement between the panel 110 and the chassis 120, and does not bear the mutual fixation between the chassis 120 and the panel 110 and 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 adopt the existing fixation mode, such as the mutual fixation between the liquid container and the chassis 120, which will not be described here.

[0050] As shown in Figure 3 The limiting protrusion 131 includes an insertion part 1312 inserted into the limiting hole 132, and the insertion part 1312 is a circular truncated cone and tapers downward. The limiting protrusion 131 also includes a base part 1311, and the insertion part 1312 is connected to the lower part of the base part 1311. The base part 1311 is used to be fixed with the lower surface of the panel 110. The fixing mode of the limiting protrusion 131, that is, the base part 1311 and the panel 110 is usually adhesion. Alternatively, it can also adopt other modes, for example, the limiting protrusion 131 is directly integrally formed on the lower surface of the panel 110. The shape of the base part 1311 is preferably the same as that of the insertion part 1312, of course, it can also be different according to needs.

[0051] The insertion part 1312 of the limiting protrusion 131 tapers downward, so that the insertion part 1312 is inserted into the limiting hole 132, and the clamping is good, no gap is left, the limiting is accurate, and the limiting protrusion 131 has a certain taper, and as the mutual fastening between the chassis 120 and the panel 110, the engagement between the insertion part 1312 and the limiting hole 132 will be tighter, so that the lateral relative position between the panel 110 and the chassis 120 is fixed.

[0052] The size of the root of the insertion part 1312 is greater than the size of the limiting hole 132. The size of the root of the insertion part 1312 is greater than the size of the limiting hole 132, so that the insertion part 1312 and the limiting hole 132 are tightly clamped, no gap is left, the limiting is accurate, and the inertia impact caused by the gap is avoided in violent impact. As shown in Figure 3 The diameter B of the root of the insertion part 1312 is greater than the diameter A1 of the limiting hole 132, and the diameter A1 of the head of the insertion part 1312 is less than the diameter B of the root of the insertion part 1312.

[0053] The inclination angle of the side surface of the insertion part 1312 with respect to the vertical direction is 1°-10°. Figure 3 The inclination angle of the side surface of the insertion part 1312 with respect to the horizontal direction is α, and 91°<α<100°. Preferably, the edge of the lower surface of the insertion part 1312 is a round corner structure. The round corner structure of the head of the insertion part 1312 can facilitate its insertion into the limiting hole 132.

[0054] The edge of the panel 110 is provided with a limiting strip 115, and the height of the limiting protrusion 131 is lower than the height of the limiting strip 115 beyond the lower surface of the panel 110. The limiting strip 115 can be a silica gel strip adhered below the edge of the panel 110 or a protective sleeve structure wrapped around 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 beyond the lower surface of the panel 110, facilitating the transportation of the cooktop 100, while not affecting the countertop gap. When the cooktop 100 is installed to the kitchen countertop, the countertop will only contact the limiting strip 115, but not the limiting protrusion 131, avoiding the installation affecting the limiting effect of the limiting structure 130.

[0056] The number of the limiting structure 130 is four and is respectively arranged at the positions corresponding to the four corners of the panel 110, and the insertion part 1312 is circularly truncated conical. In other embodiments, the cross-sectional shape of the insertion part 1312 can also not be circular, but square, diamond, etc. Considering that the circular shape is more suitable for the insertion of the insertion part 1312 and the manufacturing of the insertion part 1312, the circular shape is preferred. The inside of the insertion part 1312 can be solid or hollow and provided with reinforcing ribs to improve its supporting strength.

[0057] There are four limiting structures 130 in the embodiment, and the connecting lines of the four limiting structures 130 form a rectangle, so that each limiting structure 130 can be uniformly stressed.

[0058] The cooktop 100 of the embodiment is subjected to a drop test to verify its effect, and the drop test meets the requirements of GB / T4857.5.

[0059] In the test, the standard double-burner cooktop 100 is packed in the package after being conventionally packed, and the packed sample is dropped at a predetermined height with an inclination of 45°.

[0060] The drop test adopts a comparative example, in which the skirt 121 of the base plate 120 and the panel 110 are only adhered by double-sided adhesive. The observed results of the test are that the glass panel 110 and the liquid receiving disc have a relative displacement at the moment of dropping; the compression distance of the glass panel 110 limited by the limiting protrusion 131 exceeds 10 mm after observing the state of the foam (in the package for buffering the cooktop) after dropping; and the length of the scratch on the glass panel 110 after disassembly is 10 mm.

[0061] And the observed results of the cooktop 100 of the embodiment are that the glass panel 110 only has a local scratch on the single side of the burner of the cooktop 100 under strong light after disassembly, and the length of the scratch is less than 3 mm.

[0062] Embodiment 2

[0063] As 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 the double-sided adhesive tape is also used on one side of the panel 110, since the double-sided adhesive tape is only used on one side of the panel 110, when the panel 110 and the chassis 120 are separated due to maintenance, the panel 110 and the chassis 120 can be easily separated from the other side of the panel 110 without difficulty in separating the panel 110 and the chassis 120 due to the multiple use of the double-sided adhesive tape.

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

[0076] The stove 100 of the embodiment is subjected to a drop test to verify its effect, which meets the requirements of GB / T4857.5.

[0077] In the test, the standard double-burner stove 100 is packed in a package after being conventionally packed, and the packed sample is dropped at a predetermined height at an angle of 45°.

[0078] The drop test uses a comparative example, in which the skirt 121 of the chassis 120 and the panel 110 are only connected by the double-sided adhesive tape. The observed results of the test are that the glass panel 110 and the liquid receiving disc have a relative displacement at the moment of dropping; the compression distance of the glass panel 110 limited by the glass panel 110 is more than 10 mm after observing the state of the foam after dropping; and the length of the scratch of the glass panel 110 after being disassembled is 10 mm.

[0079] The observed results of the stove 100 of the embodiment are that the glass panel 110 only has local dense scratches around the burner of the stove 100 under strong light after being disassembled, and the length of the scratch is less than 3 mm.
