Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an electric stove. Background Technology

[0002] An electric stove is a kitchen appliance that uses an electric heating element to heat water or food. It primarily utilizes the heat dissipated when an electric current passes through a resistance wire with high resistance to achieve its heating function. For example... Figure 1 and Figure 2 As shown, an electric stove typically consists of a heating plate 1, a panel 3', and a bottom shell 4. The heating plate 1 contains a heating element, the panel 3' is mounted on the bottom shell 4, and the mounting ring 2 on the heating plate 1 is supported and mounted on the panel 3'. The limiting ring 31' of the panel 3' limits the heating plate 1 in the horizontal direction to ensure the limited installation of the heating plate 1.

[0003] In existing electric stoves, such as Figure 2 As shown, the limiting ring 31' is close to the heating plate 1, causing the heat from the heating plate 1 to be conducted to the panel 1 through the limiting ring 31', resulting in a high temperature rise of the panel 1 and easily causing safety risks such as burns. During the assembly and use of the electric stove, the heating plate 1 may move horizontally, causing the limiting ring 31' to directly contact the side wall of the heating plate 1, further aggravating the temperature rise of the panel 3'. Utility Model Content

[0004] The technical problem solved by this utility model is to provide an electric stove that can effectively solve the technical problem in the prior art where the positioning wall of the panel is close to or in contact with the heating plate, resulting in a high temperature rise of the panel.

[0005] The above-mentioned technical problems are solved by the following technical solutions:

[0006] Electric stoves, including:

[0007] A heating plate, wherein a mounting ring is integrally provided along the circumference of the heating plate;

[0008] The panel has a mounting hole, and a limiting ring is provided around the mounting hole in the circumference of the panel. An upwardly extending limiting ring is provided inside the mounting hole. The heating plate passes through the mounting hole and is supported by the mounting ring on the panel. The limiting ring is located between the mounting ring and the heating plate. The horizontal distance between the limiting ring and the mounting ring is smaller than the horizontal distance between the limiting ring and the heating plate.

[0009] The electric stove described in this utility model has the following advantages compared with the prior art:

[0010] The heating element is supported on the panel by a mounting ring. A limiting ring is located between the mounting ring and the heating element. The horizontal distance between the limiting ring and the mounting ring is smaller than the horizontal distance between the limiting ring and the heating element. This allows the limiting ring to be closer to the mounting ring and further away from the heating element. Since the temperature of the mounting ring is lower than that of the heating element, the heat transfer from the heating element to the limiting ring is reduced, which in turn reduces the heat transfer from the limiting ring to the panel, effectively lowering the panel's temperature rise. Furthermore, because the limiting ring is closer to the mounting ring and further away from the heating element, even if the heating element moves horizontally, it will only contact the mounting ring and not the limiting ring directly. This prevents the heating element from transferring heat directly to the panel through the limiting ring, thus avoiding excessive panel temperature rise.

[0011] In one embodiment, the limiting ring is inclined from bottom to top toward the center of the heating plate.

[0012] In one embodiment, the limiting ring includes:

[0013] A first limiting ring is circumferentially disposed on the panel around the mounting hole;

[0014] The second limiting ring is provided at the top of the first limiting ring, and the tilt angle of the second limiting ring is greater than the tilt angle of the first limiting ring.

[0015] In one embodiment, the included angle between the second limiting ring and the inner side of the mounting ring is α, then 10°≤α≤30°.

[0016] In one embodiment, the panel includes a main plate and a support platform. The main plate has a protruding support platform, the support platform has the mounting hole, and the mounting ring is supported on the support platform.

[0017] In one embodiment, the electric stove further includes:

[0018] The bottom shell has a panel mounted on its top and a through hole at its bottom.

[0019] A locking nut is provided, wherein the heating plate has a screw passing through the through hole, and the locking nut is threadedly connected to the screw and abuts against the bottom end of the bottom shell.

[0020] In one embodiment, a limiting cylinder is detachably disposed inside the bottom shell, the limiting cylinder is sleeved on the screw, and the two ends of the limiting cylinder abut against the heating plate and the bottom shell respectively.

[0021] In one embodiment, a limiting cylinder is integrally provided on the bottom wall of the bottom shell, the limiting cylinder is sleeved on the screw, and the end of the limiting cylinder away from the bottom shell abuts against the heating plate;

[0022] In one embodiment, the heating plate is provided with a limiting cylinder sleeved on the screw, and the end of the limiting cylinder away from the heating plate is pressed against the bottom shell.

[0023] In one embodiment, the bottom end of the bottom shell is provided with a relief groove for accommodating the screw, the relief groove is provided with the through hole, and the locking nut is pressed against the bottom wall of the relief groove. Attached Figure Description

[0031] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] In existing electric stoves, the positioning wall of the panel is close to the heating plate, causing heat from the heating plate to be conducted to the panel through the positioning wall. This results in a high temperature rise in the panel, which can easily lead to safety risks such as burns. During the assembly and use of the electric stove, the heating plate 1 may move horizontally, causing the positioning wall to come into direct contact with the side wall of the heating plate, further aggravating the temperature rise of the panel.

[0036] To solve the above problems, such as Figure 3 and Figure 4As shown, this embodiment proposes an electric stove, which includes a heating plate 1 and a panel 3. A heating element is installed inside the heating plate 1, and a mounting ring 2 is integrally provided on the heating plate 1 along its circumference. The panel 3 has a mounting hole 330, and a limiting ring 31 is provided around the mounting hole 330 in the circumference of the panel 3. The heating plate 1 passes through the mounting hole 330 and is supported by the mounting ring 2 on the panel 3. The limiting ring 31 is located between the mounting ring 2 and the heating plate 1, and the horizontal distance between the limiting ring 31 and the mounting ring 2 is smaller than the horizontal distance between the limiting ring 31 and the heating plate 1. When the heating plate 1 is supported on the panel 3 by the mounting ring 2, the limiting ring 31 is located between the mounting ring 2 and the heating plate 1. The horizontal distance between the limiting ring 31 and the mounting ring 2 is smaller than the horizontal distance between the limiting ring 31 and the heating plate 1. This allows the limiting ring 31 to be closer to the mounting ring 2 and further away from the heating plate 1. Since the temperature of the mounting ring 2 is lower than that of the heating plate 1, the heat transfer from the heating plate 1 to the limiting ring 31 is reduced, which in turn reduces the heat transfer from the limiting ring 31 to the panel 3, effectively lowering the temperature rise of the panel 3. Simultaneously, because the limiting ring 31 is closer to the mounting ring 2 and further away from the heating plate 1, even if the heating plate 1 moves horizontally, it will only contact the mounting ring 2 and will not directly contact the limiting ring 31. This prevents the heating plate 1 from directly transferring heat to the panel 3 through the limiting ring 31, thus avoiding excessive temperature rise in the panel 3.

[0037] In this embodiment, the panel 3 includes a main body plate 32 and a support platform 33. The main body plate 32 has a protruding support platform 33, and the support platform 33 has a mounting hole 330. The mounting ring 2 is supported on the support platform 33. Since the support platform 33 protrudes from the upper surface of the main body plate 32, it not only provides stable support for the heating plate 1, but also makes the height of the support platform 33 along the height direction of the panel 3 (the vertical direction in the figure) higher than the upper surface of the main body plate 32. This prevents water and other liquids from flowing from the upper surface of the main body plate 32 to the heating plate 1, giving the support platform 33 a better waterproof effect.

[0038] It should be noted that the panel 3 in this embodiment is an integrally formed structure, that is, a support platform 33 is integrally formed on the main body plate 32. The inner side of the mounting hole 330 of the support platform 33 extends from bottom to top at an angle and is provided with a limit ring 31, which improves the structural strength of the panel 3 and reduces the processing cost and processing difficulty.

[0039] Specifically, the heating plate 1 is fixed to the top wall of the mounting ring 2. The side wall of the mounting ring 2 is inclined and is a conical ring with the larger end at the bottom and the smaller end at the top. The bottom end of the side wall of the mounting ring 2 is supported on the support platform 33, and the limiting ring 31 is inclined from bottom to top towards the center of the heating plate 1. Specifically, the limiting ring 31 is inclined in the same direction as the side wall of the mounting ring 2 to facilitate the installation of the mounting ring 2 and avoid interference between the side wall of the mounting ring 2 and the limiting ring 31. Since the horizontal distance between the side wall of the mounting ring 2 and the limiting ring 31 is small, the side wall of the mounting ring 2 may come into direct contact with the limiting ring 31 when there are dimensional tolerances and installation errors. The temperature of the side wall of the mounting ring 2 decreases with distance from the heating plate 1, that is, the bottom temperature of the side wall of the mounting ring 2 is low, and the heat transfer to the limiting ring 31 is small, effectively suppressing the temperature rise of the panel 3.

[0040] In one embodiment, the limiting ring 31 includes a first limiting ring 311 and a second limiting ring 312. The first limiting ring 311 is circumferentially disposed on the panel 3 around the mounting hole 330, and the second limiting ring 312 is disposed at the top of the first limiting ring 311. The tilt angle of the second limiting ring 312 is greater than the tilt angle of the first limiting ring 311. Since the second limiting ring 312 is tilted away from the inner side of the mounting ring 2, the horizontal distance between the second limiting ring 312 and the mounting ring 2 is increased, and the contact area (i.e., heat transfer area) between the limiting ring 31 and the mounting ring 2 is reduced, thereby reducing the heat transfer from the mounting ring 2 to the limiting ring 31, and further reducing the heat transfer from the limiting ring 31 to the panel 3, thus further reducing the temperature rise of the panel 3.

[0041] It should be noted that the top of the second limiting ring 312 has the largest horizontal distance from the mounting ring 2, and the top of the second limiting ring 312 has the smallest horizontal distance from the heating plate 1. At this time, the maximum horizontal distance a between the limiting ring 31 and the mounting ring 2 is less than the minimum horizontal distance b between the limiting ring 31 and the heating plate 1, so as to ensure that the inclined second limiting ring 312 is still closer to the mounting ring 2.

[0042] In one embodiment, the angle between the second limiting ring 312 and the inner side of the mounting ring 2 is α, where 10°≤α≤30°. Specifically, the angle α can be 10°, 15°, 20°, 25°, or 30°, etc. This setting ensures that the second limiting ring 312 is kept away from the mounting ring 2 while avoiding proximity to the heating plate 1. If the angle α is too small (less than 10°), the horizontal distance between the second limiting ring 312 and the sidewall of the mounting ring 2 remains relatively short, resulting in insufficient reduction of heat transfer from the mounting ring 2 to the limiting ring 31, which is detrimental to reducing the temperature rise of the panel 3. If the angle α is too large (greater than 30°), the distance between the second limiting ring 312 and the heating plate 1 is relatively short, increasing the heat transfer from the heating plate 1 to the limiting ring 31 and exacerbating the temperature rise of the panel 3.

[0043] In one embodiment, such as Figure 4 As shown, along the height direction of panel 3, the height of the limiting ring 31 is h, then 6mm ≤ h ≤ 17mm. In this embodiment, the height h can be 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, or 17mm, etc. Through the above settings, the limiting ring 31 has a suitable height, ensuring waterproofing while effectively controlling the contact area between the limiting ring 31 and the mounting ring 2, thereby reducing the heat transfer from the mounting ring 2 to the panel 3 through the limiting ring 31, thus controlling the temperature rise of the control panel 3. Specifically, along the height direction of panel 3, the height of the first limiting ring 311 is h1, then 2mm ≤ h1 ≤ 5mm; along the height direction of panel 3, the height of the second limiting ring 312 is h2, then 4mm ≤ h2 ≤ 12mm. In this embodiment, the height h1 can be 2mm, 3mm, 4mm, or 5mm, etc., and the height h2 can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, or 12mm, etc. In other embodiments, the heights h, h1, and h2 described above can be flexibly adjusted as needed, and are not specifically limited here.

[0044] like Figure 3 As shown, the electric stove provided in this embodiment also includes a bottom shell 4 and a locking nut 5. The panel 3 is installed on the top of the bottom shell 4, and a through hole 410 is provided at the bottom end of the bottom shell 4. The heating plate 1 has a screw 11 passing through the through hole 410. The locking nut 5 is threadedly connected to the screw 11 and abuts against the bottom end of the bottom shell 4. When the mounting ring 2 of the heating plate 1 is supported on the support platform 33, the screw 11 at the bottom of the heating plate 1 passes through the through hole 410 of the bottom shell 4, and the locking nut 5 is threadedly tightened with the screw 11 that passes through the bottom shell 4. The locking nut 5 abuts against the bottom end of the bottom shell 4, so as to achieve a stable installation of the heating plate 1 through the tension of the locking nut 5.

[0045] In one embodiment, a limiting cylinder 6 is detachably provided inside the bottom shell 4. The limiting cylinder 6 is sleeved on the screw 11, and its two ends abut against the heating plate 1 and the bottom shell 4, respectively. Because the limiting cylinder 6 is clamped between the heating plate 1 and the bottom shell 4, when the locking nut 5 is tightened, the heating plate 1 gradually moves closer to the bottom shell 4 under the pull of the locking nut 5. When the two ends of the limiting cylinder 6 abut against the heating plate 1 and the bottom shell 4, the locking nut 5 is fully tightened. At this point, the mounting ring 2 of the heating plate 1 is just supported on the support platform 33, and the panel 3 does not show significant deformation. By setting the limiting cylinder 6, the degree of tightening of the locking nut 5 is kept consistent, preventing the heating plate 1 from shaking on the panel 3 due to insufficient tightening of the locking nut 5, or preventing the panel 3 from being subjected to excessive pressure from the heating plate 1 (mounting ring 2) due to over-tightening of the locking nut 5, resulting in significant deformation.

[0046] In this embodiment, the limiting cylinder 6 is an independent component, facilitating its disassembly and replacement. Alternatively, in another embodiment, the bottom wall of the bottom shell 4 is integrally provided with the limiting cylinder 6, which is sleeved on the screw 11, with the end of the limiting cylinder 6 away from the bottom shell 4 abutting against the heating plate 1. Or, the heating plate 1 is provided with a limiting cylinder 6 sleeved on the screw 11, with the end of the limiting cylinder 6 away from the heating plate 1 abutting against the bottom shell 4. By making the limiting cylinder 6 an integral structure with the bottom shell 4 or the heating plate 1, the installation of the limiting cylinder 6 is unnecessary.

[0047] like Figure 3 As shown, the bottom end of the base shell 4 has an inwardly facing relief groove 41 to accommodate the screw 11. A through hole 410 is opened in the relief groove 41, and the locking nut 5 is pressed against the bottom wall of the relief groove 41. By setting the relief groove 41, the part of the screw 11 extending out of the base shell 4 is completely accommodated in the relief groove 41, which facilitates the installation of the locking nut 5. At the same time, the length of the screw 11 will not increase the overall height of the electric stove, so as to ensure that the base shell 4 of the electric stove is placed flat in the designated position.

[0048] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments.
