Description

Technical Field

[0001] This application relates to the field of cooking appliance technology, and more particularly to an induction cooker. Background Technology

[0002] In order to accommodate the curved bottom of a wok, some existing induction cookers have a concave panel. To prevent the wok from contacting the concave panel and to allow users to perform actions such as tossing the wok, a support steel ring is set along the outer perimeter of the concave panel to support the wok. The support steel ring is supported on a glass plate, which in turn is supported on the top cover. The lower surface of the top cover has a downward-protruding top cover support column, and the lower cover has an upward-protruding bottom cover support column. The top cover support column is supported on the bottom cover support column.

[0003] The weight of the wok is transmitted through its components: supporting steel ring → glass plate → upper cover → upper cover support column → lower cover support column → lower cover → tabletop. During this force transmission, torque is generated in each component, causing deformation of the glass plate, upper cover, and lower cover. The upper and lower covers, in particular, are less rigid and deform more significantly, reducing the distance between the lower cover and the wok. Since the induction cooker's coil is fixed to the lower cover, this reduces the induction cooker's working distance (the relative distance between the wok and the coil), thus affecting product performance and potentially leading to inaccurate temperature measurement and failure to pass electromagnetic compatibility tests. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides an induction cooker to reduce the torque generated by the weight of the wok during transmission, thereby reducing the deformation of the upper and lower lids and thus ensuring product performance.

[0005] This application provides an induction cooker, including an upper cover, a lower cover, a panel, and a support ring. The upper cover is mounted on the lower cover and has a mounting opening. The panel is mounted at the mounting opening. The support ring surrounds the panel and its outer periphery supports the area above the upper cover. A first support column protruding downwards is provided on the lower surface of the upper cover and in a predetermined area corresponding to the outer periphery of the support ring in the vertical direction. A second support column protruding upwards is provided on the lower cover, and the first support column is supported on the second support column.

[0006] In some embodiments, the outer periphery of the support ring is formed with an annular support surface facing the upper surface of the cover, and the shortest horizontal distance between the central axis of the first support column and the radial center circumference of the annular support surface is less than 20 mm.

[0007] In some embodiments, a heat insulation ring is provided between the upper surface of the cover and the outer periphery of the support ring, the heat insulation ring being supported on the upper surface of the cover, and the outer periphery of the support ring being supported on the heat insulation ring.

[0008] In some embodiments, the upper surface of the top cover is formed with an upwardly protruding annular boss around the mounting opening, and the lower surface of the heat insulation ring is formed with a first support surface, which is supported on the annular boss.

[0009] The upper surface of the heat insulation ring has a second support surface that corresponds to the first support surface above and below, and the outer periphery of the support ring is supported on the second support surface.

[0010] In some embodiments, the upper surface of the cover has an upwardly protruding annular rib around the mounting opening, and the lower surface of the heat insulation ring has an annular groove, the annular rib being inserted into the annular groove.

[0011] In some embodiments, a plurality of support ribs are connected between the lower surface of the upper cover and the outer peripheral surface of the first support column. The plurality of support ribs are spaced apart along the circumference of the first support column, and the downward projection of at least one support rib overlaps with the downward projection of the outer peripheral edge of the support ring.

[0012] In some embodiments, there are multiple first support columns, which are spaced apart around the mounting opening, and the central axes of the multiple first support columns are all located in the inner or outer region of the outer periphery of the support ring.

[0013] In some embodiments, the lower surface of the lower cover is formed with a downwardly protruding support foot, which is vertically corresponding to the second support column.

[0014] In some embodiments, the first support column has a first mounting hole with an opening at the lower end, the lower cover has a second mounting hole that passes through the support base and the second support column, and the lower cover is connected to the upper cover by fasteners that pass through the second mounting hole and the first mounting hole.

[0015] In some embodiments, an anti-abrasion pad is installed at the support foot, and the lower end of the anti-abrasion pad protrudes from the lower surface of the support foot.

[0016] The technical solution provided in this application has at least the following advantages compared with the prior art:

[0017] 1. By supporting the outer periphery of the support ring on the upper area of ​​the top cover, and providing a downwardly protruding first support column in a preset area on the lower surface of the top cover corresponding to the outer periphery of the support ring in the vertical direction, that is, the first support column is set to correspond or approximately correspond to the outer periphery of the support ring in the vertical direction. With this setting, when a wok is placed on the induction cooker, the weight of the wok can be transferred to the support ring, then to the first support column of the top cover, and then to the tabletop through the second support column of the bottom cover. Since the outer periphery of the support ring and the first support column are set to correspond or approximately correspond to each other in the vertical direction, the torque and torsional force generated during the force transmission process can be reduced, thereby reducing the deformation of the top and bottom covers, ensuring the stable and reliable working distance of the induction cooker, thus ensuring product performance and avoiding problems such as inaccurate temperature measurement and failure to pass electromagnetic compatibility tests.

[0018] 2. By setting a heat insulation ring between the upper surface of the lid and the outer perimeter of the support ring, the heat transfer can be effectively blocked, reducing the heat transferred from the wok to the lid through the support ring. This prevents the lid from overheating and burning the user, and also prevents the lid from overheating and causing adverse effects on electrical components installed on the lid.

[0019] 3. By connecting multiple support ribs between the lower surface of the top cover and the outer peripheral surface of the first support column, the multiple support ribs are spaced apart along the circumference of the first support column, and the downward projection of at least one support rib overlaps with the downward projection of the outer peripheral edge of the support ring. In this way, the structural strength of the top cover can be strengthened by the support ribs, reducing the deformation of the top cover. At the same time, the weight of the wok can be transferred to the first support column of the top cover more evenly, thereby more effectively reducing the deformation of the top cover.

[0020] 4. By forming a downwardly protruding support foot on the lower surface of the lower cover, the support foot is positioned vertically corresponding to the second support column. This arrangement ensures that the support foot and the second support column are in the same vertical direction, thereby preventing the weight of the wok from generating torque during the transmission from the second support column to the support foot, which could cause the lower cover to deform. Anti-abrasion pads are installed at the support feet, with the lower end of the anti-abrasion pads protruding from the lower surface of the support foot. When the induction cooker is placed on the table, the anti-abrasion pads contact and support the table, ensuring that the induction cooker can be placed stably on the table during cooking and protecting the table from scratches or marks.

[0034] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0036] Reference Figures 1 to 9 As shown, some embodiments of this application provide an induction cooker 100, including an upper cover 1, a lower cover 2, a panel 3, and a support ring 4.

[0037] The upper cover 1 is mounted on the lower cover 2, and the upper cover 1 has a mounting opening 101. The panel 3 is mounted at the mounting opening 101. In order to accommodate the curved bottom surface of the wok 200, the panel 3 can be a concave panel.

[0038] A support ring 4 is arranged around the panel 3, and the outer periphery 401 of the support ring 4 supports the area above the upper cover 1. The support ring 4 supports the wok 200, preventing the wok 200 from contacting the panel 3, and making it convenient for the user to perform actions such as tossing the wok.

[0039] It should be noted that the outer peripheral edge 401 of the support ring 4 can be directly supported on the upper surface of the cover 1 or indirectly supported on the upper surface of the cover 1. For example, a heat insulation ring 5 is provided between the support ring 4 and the cover 1. The heat insulation ring 5 is supported on the upper surface of the cover 1, and the outer peripheral edge 401 of the support ring 4 is supported on the heat insulation ring 5.

[0040] The lower surface of the upper cover 1 and the outer periphery of the support ring 4 are provided with a first support column 102 protruding downward in a preset area along the vertical direction of 401. The lower cover 2 is provided with a second support column 201 protruding upward. The first support column 102 is supported on the second support column 201.

[0041] It should be understood that in the above embodiment, "a downwardly protruding first support post 102 is provided in a preset area corresponding to the lower surface of the upper cover 1 and the outer periphery of the support ring 4 along the vertical direction 401". That is, the first support post 102 is located within a certain area corresponding to the outer periphery of the support ring 4 along the vertical direction 401. The first support post 102 can be aligned with the outer periphery of the support ring 4 along the vertical direction 401, or there can be a small deviation. In other words, the first support post 102 is set correspondingly or approximately correspondingly to the outer periphery of the support ring 4 along the vertical direction 401.

[0042] For example, the first support column 102 can be directly opposite the outer periphery 401 of the support ring 4 in the vertical direction, that is, the first support column 102 can be located in the same vertical direction as the outer periphery 401 of the support ring 4, or the central axis of the first support column 102 can pass through the outer periphery 401 of the support ring 4; the central axis of the first support column 102 can also be located in the inner region of the outer periphery 401 of the support ring 4, and relatively close to the outer periphery 401 of the support ring 4; the central axis of the first support column 102 can also be located in the outer region of the outer periphery 401 of the support ring 4, and relatively close to the outer periphery 401 of the support ring 4.

[0043] In addition, the projection of the first support column 102 downward in the vertical direction can overlap with the projection of the outer periphery edge 401 of the support ring 4 downward in the vertical direction, which can also realize that the first support column 102 is set relative to the outer periphery edge 401 of the support ring 4 in the horizontal direction.

[0044] It should be noted that the terms "upper" and "lower" in the above embodiments are used with reference to the state in which the induction cooker 100 is placed on a horizontal table. They are used only for the convenience of description and are not intended to limit the specific structure and usage state of the induction cooker 100.

[0045] The induction cooker 100 provided in this application embodiment supports the outer periphery 401 of the support ring 4 on the upper area of ​​the upper cover 1. A first support column 102 protrudes downward in a preset area on the lower surface of the upper cover 1 that corresponds vertically to the outer periphery 401 of the support ring 4. That is, the first support column 102 and the outer periphery 401 of the support ring 4 are arranged in a vertically corresponding or approximately corresponding manner. When a wok 200 is placed on the induction cooker 100, the weight of the wok 200 can be transferred to the support ring 4, and then to the first support column 102 of the upper cover 1 through the support ring 4, and then to the tabletop through the second support column 201 of the lower cover 2. Since the outer periphery 401 of the support ring 4 and the first support column 102 are arranged in a vertically corresponding or approximately corresponding manner, the torque and torsional force generated during the force transmission process can be reduced, thereby reducing the deformation of the upper cover 1 and the lower cover 2, thus ensuring the stable and reliable working distance of the induction cooker 100, thereby ensuring product performance and avoiding problems such as inaccurate temperature measurement and electromagnetic compatibility test failure.

[0046] It should be understood that the working principle of the induction cooker 100 is based on the principle of electromagnetic induction heating. A coil 7 is installed on the lower cover 2 of the induction cooker 100. When an alternating current is passed through the coil 7, an alternating magnetic field with a constantly changing direction is generated. Eddy currents will appear inside the wok 200 in this magnetic field. The Joule heating effect of the eddy currents will cause the wok 200 to heat up, thereby achieving the heating effect.

[0047] Reference Figure 3 and Figure 4 As shown, a coil 7 is installed on the lower cover 2, the panel 3 is located above the coil 7, the wok 200 is placed above the panel 3, and the working distance of the induction cooker 100 is the relative distance between the wok 200 and the coil 7.

[0048] If the upper cover 1 and lower cover 2 deform significantly during use, the distance between the lower cover 2 and the wok 200 will decrease, which in turn will reduce the distance between the coil 7 and the wok 200, affecting product performance and potentially leading to inaccurate temperature measurement and electromagnetic compatibility (EMC) failure. The induction cooker 100 provided in this embodiment reduces the torque and torsional force generated during force transmission, thereby reducing the deformation of the upper cover 1 and lower cover 2. This ensures a stable and reliable working distance for the induction cooker 100, guaranteeing product performance and preventing issues such as inaccurate temperature measurement and EMC failure.

[0049] Reference Figure 3 , Figure 4 and Figure 6As shown, to prevent the heat from the wok 200 from being transferred to the coil 7 and affecting its normal operation, a heat insulation plate 8 is provided between the coil 7 and the panel 3. To achieve precise temperature control of the induction cooker 100, a temperature probe 9 is provided on the lower cover 2.

[0050] In some embodiments, refer to Figure 4 and Figure 5 As shown, the outer periphery of the support ring 4 is formed with an annular support surface 402 facing the upper surface of the upper cover 1. The shortest horizontal distance between the central axis of the first support column 102 and the radial center circumference of the annular support surface 402 is less than 20 mm.

[0051] It should be noted that the annular support surface 402 has an annular inner edge contour line and an outer edge contour line. The radially oriented central circumference of the annular support surface 402 is located between the inner edge contour line and the outer edge contour line, and the distance from the central circumference line to the inner edge contour line is equal to the distance from the central circumference line to the outer edge contour line. It should be understood that the radially oriented central circumference of the annular support surface 402 can be considered as the support center of the annular support surface 402.

[0052] Reference Figure 4 and Figure 5 As shown in the figure, E represents the support center of the annular support surface 402; F represents the central axis of the first support column 102, which can be considered as the support center of the first support column 102; D represents the shortest horizontal distance between E and F, where D < 20 mm.

[0053] This arrangement ensures that the support center of the annular support surface 402 and the support center of the first support column 102 are located in the same vertical direction. Alternatively, even if they are not located in the same vertical direction, they can be positioned close to each other, i.e., the support center of the first support column 102 is positioned horizontally close to the support center of the annular support surface 402. This results in a smaller torque generated by the weight of the wok 200, a smaller torque on the upper cover 1 and lower cover 2, and negligible deformation of the upper cover 1 and lower cover 2. Since the coil 7 is mounted on the lower cover 2, the distance between the coil 7 and the wok 200 changes less, thus making the induction cooker 100 operate more stably and reliably.

[0054] In practice, the value of D can be reasonably selected and set according to the actual situation. For example, D can be 0mm, 5mm, 10mm, 15mm, etc.

[0055] In some embodiments, refer to Figure 1 , Figures 3 to 6As shown, a heat insulation ring 5 is provided between the upper surface of the cover 1 and the outer periphery 401 of the support ring 4. The heat insulation ring 5 is supported on the upper surface of the cover 1, and the outer periphery 401 of the support ring 4 is supported on the heat insulation ring 5.

[0056] This design effectively blocks heat transfer, reducing the amount of heat transferred from the wok 200 to the upper cover 1 via the support ring 4. This prevents the upper cover 1 from overheating and burning the user, and also prevents the upper cover 1 from overheating and causing adverse effects on electrical components installed on it.

[0057] In practice, the support ring 4 can be made of steel to ensure that the support ring 4 has sufficient structural strength; the heat insulation ring 5 can be made of plastic ring, rubber ring, etc., which have good heat insulation effect.

[0058] Reference Figure 4 and Figure 6 As shown, a display panel is provided on the upper cover 1, and electrical components are provided on the display panel. The number of display panels is not limited to one, but can also be two. For example, there are two display panels, namely a first display panel 10 and a second display panel 11. The first display panel 10 is displayed through the front side of the upper cover 1, and the second display panel 11 is displayed through the upper front of the upper cover 1. Specifically, the first display panel 10 can be used to display cooking functions, etc., and the second display panel 11 can be used to display cooking power, etc. In addition, a knob 12 is also provided on the upper cover 1 to adjust the power and other parameters of the induction cooker 100 by rotating the knob 12.

[0059] In some embodiments, refer to Figure 4 and Figure 5 As shown, the upper surface of the cover 1 has an upwardly protruding annular boss 103 formed around the mounting opening 101, the lower surface of the heat insulation ring 5 has a first support surface 501, and the first support surface 501 is supported on the annular boss 103; the upper surface of the heat insulation ring 5 has a second support surface 502 that corresponds vertically to the first support surface 501, and the outer periphery 401 of the support ring 4 is supported on the second support surface 502.

[0060] This configuration ensures the stability of the heat insulation ring 5 on the upper surface of the cover 1 by supporting it on the annular boss 103 via the first support surface 501; and ensures the stability of the outer periphery 401 of the support ring 4 on the heat insulation ring 5 by supporting it on the second support surface 502 via the outer periphery 401 of the support ring 4.

[0061] In some embodiments, refer to Figure 4 and Figure 5 As shown, the upper surface of the cover 1 has an upwardly protruding annular rib 104 surrounding the mounting opening 101, and the lower surface of the heat insulation ring 5 has an annular groove 503, in which the annular rib 104 is inserted.

[0062] This configuration ensures the stability of the heat insulation ring 5 on the upper surface of the cover 1 by inserting the annular reinforcing rib 104 into the annular groove 503, thereby ensuring the stability of the heat insulation ring 5 supporting the support ring 4.

[0063] It should be noted that, referring to Figure 4 and Figure 5 As shown, in order to support the wok 200 using the support ring 4 and prevent the wok 200 from contacting the panel 3, the outer periphery 401 of the support ring 4 is supported above the upper cover 1, and the inner periphery 403 of the support ring 4 can be located above the panel 3. Specifically, the support ring 4 can have an upwardly arched structure, with the apex of the arch located above the panel 3, so that the wok 200 is supported by the portion of the apex of the arch relatively close to the inner periphery 403; and the inner periphery 403 of the support ring 4 is set higher than the outer periphery 401 of the support ring 4, so that the weight of the wok 200 is not transmitted to the panel 3 through the inner periphery 403 of the support ring 4, but is transmitted to the upper cover 1 through the outer periphery 401 of the support ring 4.

[0064] In some embodiments, refer to Figures 7 to 9 As shown, a plurality of support ribs 105 are connected between the lower surface of the upper cover 1 and the outer peripheral surface of the first support column 102. The plurality of support ribs 105 are spaced apart along the circumferential direction of the first support column 102, and the downward projection of at least one support rib 105 overlaps with the downward projection of the outer peripheral edge 401 of the support ring 4.

[0065] For example, refer to Figure 9 The diagram shown is a cross-sectional view of an induction cooker 100 provided in an embodiment of this application at the first support column 102 and one of the support ribs 105. The longitudinal section of the support rib 105 is an inverted triangle, and the projection of the support rib 105 downward in the vertical direction overlaps with the projection of the outer periphery of the support ring 4 downward in the vertical direction along the 401.

[0066] With this configuration, the structural strength of the upper cover 1 can be enhanced by the support ribs 105, reducing the deformation of the upper cover 1. At the same time, the weight of the wok 200 can be transferred more evenly to the first support column 102 of the upper cover 1, thereby more effectively reducing the deformation of the upper cover 1.

[0067] In other embodiments, reference is made to Figure 4 and Figure 5As shown, the upper surface of the cover 1 has an upwardly protruding annular boss 103 formed around the mounting opening 101, the lower surface of the heat insulation ring 5 has a first support surface 501, and the first support surface 501 is supported on the top end face of the annular boss 103; the upper surface of the heat insulation ring 5 has a second support surface 502 that corresponds vertically to the first support surface 501, and the outer periphery 401 of the support ring 4 is supported on the second support surface 502.

[0068] In other words, the outer periphery 401 of the support ring 4 is directly supported on the second support surface 502, and the weight of the wok 200 is directly transmitted to the second support surface 502 through the outer periphery 401 of the support ring 4. Therefore, at least one support rib 105 can be provided so that its projection downward in the vertical direction overlaps with the projection of the second support surface 502 downward in the vertical direction.

[0069] Furthermore, the outer periphery 401 of the support ring 4 is directly supported on the second support surface 502 of the heat insulation ring 5, while the heat insulation ring 5 is directly supported on the top end face of the annular boss 103 of the upper cover 1. That is, the outer periphery 401 of the support ring 4 is indirectly supported on the top end face of the annular boss 103 of the upper cover 1. The weight of the wok 200 is directly transmitted to the second support surface 502 of the heat insulation ring 5 through the outer periphery 401 of the support ring 4, and then to the top end face of the annular boss 103 of the upper cover 1 through the heat insulation ring 5. Therefore, at least one support rib 105 can be provided so that its projection downward in the vertical direction overlaps with the projection of the top end face of the annular boss 103 downward in the vertical direction.

[0070] In some embodiments, refer to Figure 7 As shown, there are multiple first support columns 102, which are spaced around the mounting opening 101. The central axes of the multiple first support columns 102 are all located in the inner area of ​​the outer periphery 401 of the support ring 4.

[0071] In other embodiments, there are multiple first support columns 102, which are spaced apart around the mounting opening 101, and the central axes of the multiple first support columns 102 are all located in the outer periphery 401 of the support ring 4.

[0072] This configuration utilizes multiple first support pillars 102 to support the support ring 4, distributing the force transmitted from the wok 200 to the support ring 4 across the multiple first support pillars 102, thereby ensuring the uniformity of the force on the top cover 1. The central axes of the multiple first support pillars 102 are all located within or outside the outer perimeter 401 of the support ring 4, further ensuring the uniformity of the force on the top cover 1 by distributing the force transmitted from the wok 200 to the support ring 4 more evenly across the multiple first support pillars 102.

[0073] In some embodiments, refer to Figure 4 and Figure 5 As shown, a support groove 202 is formed on the top end face of the second support column 201, and the bottom end face of the first support column 102 is supported at the support groove 202. This arrangement ensures the stability of the second support column 201 in supporting the first support column 102.

[0074] In some embodiments, refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the lower surface of the lower cover 2 has a downwardly protruding support foot 203, which is arranged vertically and vertically with the second support column 201.

[0075] This configuration allows the weight of the wok 200 to be transferred to the support foot 203 via the second support column 201. The support foot 203 supports the wok 200, and the support foot 203 is vertically aligned with the second support column 201, meaning they are located in the same vertical direction. This reduces the torque and torsion generated during force transmission, thereby reducing the deformation of the upper cover 1 and lower cover 2. This ensures a stable and reliable working distance for the induction cooker 100, thus guaranteeing product performance.

[0076] In some embodiments, refer to Figure 4 and Figure 5 As shown, a first mounting hole 106 with an opening at the lower end is formed on the first support column 102, and a second mounting hole 204 through the support foot 203 and the second support column 201 is formed on the lower cover 2. The lower cover 2 is connected to the upper cover 1 by fasteners that pass through the second mounting hole 204 and the first mounting hole 106, so as to ensure the reliability of the fixed connection between the lower cover 2 and the upper cover 1 by using fasteners.

[0077] In a specific implementation, the second mounting hole 204 can be formed as a stepped hole. The second mounting hole 204 includes a first hole segment and a second hole segment connected to each other. The second hole segment is located below the first hole segment, and the diameter of the second hole segment is larger than that of the first hole segment. The fastener can be a screw. The stud of the screw passes through the first hole segment and is threadedly connected to the first mounting hole 106. The nut of the screw is located in the second hole segment and abuts against the step formed between the second hole segment and the first hole segment.

[0078] In some embodiments, refer to Figure 3 , Figure 4 and Figure 6 As shown, an anti-wear pad 6 is installed at the support foot 203, and the lower end of the anti-wear pad 6 protrudes from the lower surface of the support foot 203.

[0079] This design allows the weight of the wok 200 to be transferred to the anti-abrasion pad 6 via the support foot 203. The anti-abrasion pad 6 supports the wok 200. When the induction cooker 100 is placed on the table, the anti-abrasion pad 6 contacts and supports the table, ensuring that the induction cooker 100 can be placed stably on the table during cooking and protecting the table from scratches or marks.

[0080] In specific implementation, the bottom of the support foot 203 forms an installation platform, and the second installation hole 204 is set through the bottom surface of the installation platform. The top of the anti-wear pad 6 is inserted into the second installation hole 204 through the installation platform. A limiting step is formed on the outer peripheral surface of the anti-wear pad 6. The limiting step abuts against the bottom surface of the installation platform to realize the limiting of the anti-wear pad 6 in the installation platform.

[0081] In specific implementation, there can be multiple anti-wear pads 6, which are distributed at the bottom of the lower cover 2, and each anti-wear pad 6 is set to correspond one-to-one with a multiple supporting feet 203.
