Description

Technical Field

[0001] This application relates to kitchen appliances, specifically to an induction cooker. Background Technology

[0002] Cooking heating equipment is a device that can heat cooking utensils to cook food, such as including but not limited to induction cookers, ceramic cookers, gas stoves, and hybrid cooktops.

[0003] During cooking, to better control the cooking effect, cooking heating equipment is usually equipped with a temperature sensing component to detect the real-time temperature of the heated cooking utensils. To ensure the accuracy of temperature detection, the temperature sensing head of the component extends beyond the panel of the cooking heating equipment in a floating support manner. During cooking, the cooking utensils can press against the temperature sensing head, causing it to move inward under pressure, thus ensuring close contact between the temperature sensing head and the cooking utensils and improving the accuracy of real-time temperature detection. Because the temperature sensing head needs to float, a through hole is made in the panel for the temperature sensing head to pass through. The diameter of the through hole must be larger than the outer diameter of the temperature sensing head to create a gap between the temperature sensing head and the wall of the through hole, ensuring smooth movement of the temperature sensing head. However, in this structure, this gap leads to the interior of the equipment, which can easily allow liquid from the outside of the panel to flow into the interior of the equipment, causing damage to internal components (such as circuit boards), leading to equipment failure or danger.

[0053] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0054] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0055] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0056] This application provides a cooking heating device capable of heating a cooking appliance to cook food. This cooking heating device may include, but is not limited to, devices capable of heating cooking appliances such as induction cookers, ceramic cooktops, gas stoves, and combination cooktops. The cooking appliance can be used to hold food and may include, but is not limited to, various pots, grills, and other utensils.

[0057] Please refer to Figure 1-3 In some embodiments, the cooking heating device is described using an induction cooker 1 as an example. Of course, in other embodiments, the cooking heating device can also be an electric ceramic stove, a gas stove, or a combination stove, or other cooking heating devices.

[0058] Please refer to Figure 1-3 In some embodiments, the induction cooker 1 includes a housing 100, a heating element (not shown in the figure), and a temperature measuring element 200. Of course, the induction cooker 1 may also include other related components, such as a control unit (not shown in the figure), which can be used to control the heating element and the temperature measuring element 200, etc. These related components can be found in existing induction cookers 1.

[0059] The housing 100 has a mounting cavity 101, within which the heating assembly, temperature sensing assembly 200, control unit, and other components can be installed, resulting in a cleaner appearance for the induction cooker 1. The housing 100 is typically assembled from two or more sub-components. The heating assembly, located within the mounting cavity 101, is used to heat the cooking appliance.

[0060] The heating element of this induction cooker 1 can achieve heating using the principle of electromagnetic induction. For example, the heating element uses alternating current passing through a coil to generate a constantly changing alternating magnetic field. Eddy currents are generated within the cooking appliance placed in the alternating magnetic field. The Joule effect of the eddy currents increases the temperature of the conductor, thereby achieving heating. Of course, in other types of cooking heating devices, the heating element can also use other forms of heating, such as the heating elements of an electric ceramic cooktop, gas stove, or combination cooktop.

[0061] Please refer to Figure 1-3 In some embodiments, the housing 100 includes a panel 110. In some embodiments, the heating element may be positioned directly below the panel 110 to heat cooking appliances on the panel 110. The panel 110 serves to support the cooking appliances and is heated by the heating element. Of course, in other cooking heating devices, such as gas stoves, the panel 110 may simply be part of the housing 100 and not be used to support cooking appliances. The panel 110 may be made of various panel materials and structures commonly used in cooking heating devices, such as glass or ceramic.

[0062] Please refer to Figure 1-3 In some embodiments, the panel 110 has a first through-hole 111 for accommodating the temperature sensing component 200. Please refer to... Figure 4 as well as Figure 7-9In some embodiments, the temperature measuring component 200 has a temperature measuring head 210 and a support base 220. The temperature measuring head 210 has a temperature sensor (not shown in the figure), which can be selected from various structures capable of temperature measurement, such as thermistors, thermocouples, or other types of sensors. The temperature measuring head 210 extends from the first through hole 111 outside the panel 110 to measure the temperature of the cooking appliance. The support base 220 is connected to the housing 100 and forms a floating support for the temperature measuring head 210, allowing the temperature measuring head 210 to move into the housing 100 under the pressure of the cooking appliance. This floating support is typically an elastic support, and its structure provides a supporting force to the temperature measuring head 210, allowing it to remain extended from the first through hole 111 outside the panel 110 under normal conditions. When the cooking appliance is placed on the panel 110, the appliance presses down on the temperature measuring head 210, causing it to retract inward. The floating support structure enables the temperature sensor 210 to maintain close contact with the cooking appliance when it is placed on the panel 110, thus ensuring more accurate temperature measurement results.

[0063] Please refer to Figure 4 , 9 In some embodiments, the peripheral outer wall of the temperature sensor 210 is formed with a drainage channel 301 (as shown by the dashed arrow), within which the temperature sensor 210 can move. The drainage channel 301 is at least partially arranged around the peripheral outer wall of the temperature sensor 210, wherein the peripheral outer wall of the temperature sensor 210 forms at least a portion of the channel wall of the drainage channel 301. The drainage channel 301 serves two purposes: firstly, it ensures that the temperature sensor 210 can move relative to the panel 110; secondly, it has an inlet 302 and an outlet 303 that communicate with each other, with the inlet 302 being higher than the outlet 303, so that liquid entering from the inlet 302 can be discharged from the outlet 303 to the outside of the housing 100. To prevent liquid from entering the mounting cavity 101, in some embodiments the drain channel 301 is sealed and separated from the mounting cavity 101 to prevent liquid from entering the mounting cavity 101 from the drain channel 301 and damaging the components inside the mounting cavity 101, especially to prevent damage to the electrical components inside the mounting cavity 101. The electrical components may include, but are not limited to, control units, heating components, weighing sensors, horns, antennas, etc.

[0064] At least a portion of the drain channel 301 may be formed by the temperature sensor 210 and other components. These other components may be components within the temperature sensor assembly 200 other than the temperature sensor 210, or components in the cooking heating device other than the temperature sensor assembly 200.

[0065] Please refer to Figure 4 as well as Figure 8 and9 In some embodiments, the support base 220 forms a floating cavity 223 with a temperature sensor protrusion 2223. The temperature sensor 210 has a first portion 201 and a second portion 202. The second portion 202 is located within the floating cavity 223 and is floatingly connected to the support base 220. The first portion 201 extends from the temperature sensor protrusion 2223 into the first through hole 111 of the panel 110, forming a first gap 304 with the wall of the first through hole 111. The second portion 202 forms a second gap 305 with the cavity wall of the floating cavity 223. The first gap 304 and the second gap 305 communicate to form at least a portion of the drainage channel 301. Of course, in some embodiments, the first gap 304 and the second gap 305 can directly form the entire drainage channel 301.

[0066] Please refer to Figure 8 and 9 In some embodiments, to ensure that the support base 220 can form a second gap 305 with the temperature measuring head 210 while also allowing the temperature measuring head 210 to move smoothly relative to the support base 220, the wall of the temperature measuring head protrusion 2223 of the support base 220 is provided with a plurality of protrusions 2224 facing the temperature measuring head 210. These protrusions 2224 can limit the movement of the temperature measuring head 210 to ensure that it runs along a specific track. A gap is provided between the protrusions 2224 to form the second gap 305.

[0067] Of course, the above-described drainage channel 301 can also be formed using other structures in other embodiments. Please refer to... Figure 10 In some embodiments, the support 220 extends into and is sealed within the first through hole 111 of the panel 110. In this case, the support 220 and the panel 110 are sealed and fixedly connected. Since there is no need for relative movement between the support 220 and the panel 110, the sealing and fixing structure can be more easily achieved, for example, by using a sealing ring. There is no need to leave a gap between the support 220 and the panel 110.

[0068] Please refer to Figure 10 In some embodiments, the support base 220 forms a floating cavity 223 with a temperature sensor protrusion 2223. The temperature sensor 210 has a first portion 201 and a second portion 202. The second portion 202 is located within the floating cavity 223 and is floatingly connected to the support base 220. The first portion 201 extends out of the temperature sensor protrusion 2223. At least a portion of the drain channel 301 is formed by the temperature sensor 210 and the support base 220.

[0069] In addition to the structures for forming the drainage channel 301 shown in the above embodiments, other structures can also be used to form the drainage channel 301 in other embodiments.

[0070] Furthermore, in order to prevent the drain channel 301 from communicating with the mounting cavity 101, please refer to... Figure 4 as well as Figure 7-9 In some embodiments, the support base 220 is sealed to the inner side of the panel 110, forming a sealed structure between the support base 220 and the panel 110 to seal and separate the first gap 304 and the second gap 305 from the mounting cavity 101. Furthermore, the sealed connection between the support base 220 and the panel 110 can also form an independent sealed structure for the drain channel 301, allowing liquid to leak from the drain channel 301 into other spaces of the equipment. The support base 220 and the panel 110 can be fixedly connected by bonding, welding, snap-fitting, screwing, or other methods. To achieve or enhance the sealing effect, a sealing element can also be provided between the support base 220 and the panel 110 to improve the sealing effect.

[0071] Please refer to Figure 4 as well as Figure 7-9 In some embodiments, the support 220 has a connecting portion 2221 surrounding the drain channel 301, and the support 220 is sealed and fixedly connected to the panel 110 through the connecting portion 2221. The connecting portion 2221 surrounds the drain channel 301, and when it is sealed and connected to the panel 110, it can ensure that liquid does not leak from the surrounding area of ​​the drain channel 301.

[0072] Further, please refer to Figure 4 as well as Figure 7-9 In some embodiments, the connecting portion 2221 may be designed as a disc or other plate-like structure to increase the contact surface with the panel 110, thereby improving the sealing effect between the connecting portion 2221 and the panel 110. In particular, increasing the contact surface of the connecting portion 2221 is more beneficial to the bonding and welding effect when the connecting portion 2221 is bonded or welded to the panel 110.

[0073] Further, please refer to Figure 4 as well as Figure 7-9 In some embodiments, the connecting part 2221 is bonded and fixed to the panel 110. This bonding not only enables a fixed connection but also provides a sealing effect.

[0074] Please refer to Figure 4 as well as Figure 7-9In some embodiments, to achieve a better bonding effect, the side of the connecting portion 2221 facing the panel 110 has a recessed adhesive groove 2222. The adhesive groove 2222 is filled with adhesive, and the connecting portion 2221 and the panel 110 are bonded and fixed by the adhesive. The adhesive groove 2222 is recessed towards the inside of the connecting portion 2221 (the inside of the connecting portion 2221 shown in the figure is below the illustrated connecting portion 2221), and the groove wall of the adhesive groove 2222 is convex to prevent the adhesive from flowing outwards, especially preventing the adhesive from flowing into the first gap 304 and the second gap 305.

[0075] Further, please refer to Figure 4 as well as Figure 7-9 In some embodiments, the adhesive reservoir 2222 is an annular structure that at least partially surrounds the drain channel 301 and the temperature measuring head 210, so as to form an adhesive surface surrounding the drain channel 301 and the temperature measuring head 210, thereby improving the fixing structure of the support 220 and the panel 110.

[0076] Furthermore, the support base 220 can be a one-piece molded structure, or it can be assembled from at least two parts. Please refer to [reference needed]. Figure 7-9 In some embodiments, the support base 220 includes a floating base 221 and a connecting base 222, which are fixedly connected and form a floating cavity 223. The temperature sensor 210 is floatingly connected to the floating base 221 so that the temperature sensor 210 can float relative to the floating base 221. Specifically, the temperature sensor 210 can be directly or indirectly connected to the floating base 221 through an elastic member 230, thereby forming an elastic floating connection. This allows the temperature sensor 210 to move towards the floating base 221 under the pressure of a cooking appliance, and after the cooking appliance is removed, the temperature sensor 210 can be reset outward (upward in the figure) under the action of the elastic member 230.

[0077] Please refer to Figure 7-9 In some embodiments, the floating seat 221 has an open cavity at the top, and the connecting seat 222 covers the open part of the cavity, thereby forming a floating cavity 223. The temperature measuring head protrusion 2223 is provided on the connecting part 2221 for the temperature measuring head 210 to protrude.

[0078] Please refer to Figure 7-9 In some embodiments, the connecting portion 2221 is disposed on the connecting base 222. The connecting portion 2221 may be integrally formed from the connecting base 222. In other embodiments, the connecting portion 2221 may also be fixedly connected to the connecting base 222.

[0079] Furthermore, in some embodiments, the connecting seat 222 and the floating seat 221 are detachably and fixedly connected to reduce manufacturing difficulty. This detachable and fixed connection includes, but is not limited to, snap-fit ​​and screw-fit connections. Of course, in other embodiments, the connecting seat 222 and the floating seat 221 can also be fixedly connected by adhesive bonding, welding, or other methods.

[0080] For details, please refer to Figure 7-9 In some embodiments, the connecting seat 222 and the floating seat 221 are fixedly connected by a snap-fit ​​structure. The connecting seat 222 has a cylindrical structure 2225 with a first snap-fit ​​portion. The floating seat 221 has a second snap-fit ​​portion, and the first and second snap-fit ​​portions are snapped together for fixation. Both the first and second snap-fit ​​portions can have a structure that enables mutual engagement. The hollow area of ​​the cylindrical structure 2225 communicates with the temperature sensor protrusion 2223, and the floating seat 221 is inserted into the hollow area of ​​the cylindrical structure 2225 and snapped together for fixation. This structure facilitates installation; assembly and fixation can be completed simply by plugging and connecting.

[0081] Please refer to Figure 7-9 In some embodiments, the first latching part is a latching window 2226, and the second latching part is a snap-on part 2213, which can be fastened into the first latching part. In other embodiments, the structures of the first latching part and the second latching part can also be interchanged.

[0082] There may be multiple first snap-fit ​​parts, arranged circumferentially along the cylindrical structure 2225, so that the connecting seat 222 can be fixed to the floating seat 221 at multiple points along the circumference of the cylindrical structure 2225. In some embodiments, the first snap-fit ​​parts may be spaced at the same interval to ensure a more uniform fastening force and a better fixing effect.

[0083] Further, please refer to Figure 8-9 In some embodiments, the floating seat 221 includes an inner floating seat 2211 and an outer floating seat 2212 surrounding the inner floating seat 2211, with the temperature measuring head 210 floatingly connected to the inner floating seat 2211. A second gap 305 is formed between the outer peripheral wall of the temperature measuring head 210 and the inner wall of the outer floating seat 2212. The outer floating seat 2212 has an open cavity at its upper end, with a connecting seat 222 covering the open portion of the cavity.

[0084] In some embodiments, please refer to Figure 7-9 In order to provide floating support for the temperature measuring head 210, the elastic element 230 can be sleeved on the inner floating seat 2211 and located between the inner floating seat 2211 and the temperature measuring head 210.

[0085] In some embodiments, please refer to Figure 7-9A third gap 306 is formed between the inner floating seat 2211 and the outer floating seat 2212. The third gap 306 communicates with the second gap 305 to form at least a portion of the drainage channel 301.

[0086] In this design, the upper opening of the first gap 304 is the liquid inlet 302, the second gap 305 is located below the first gap 304 and communicates with the lower end of the first gap 304, and the third gap 306 is located below the second gap 305 and communicates with the lower end of the second gap 305. In some other embodiments, the third gap 306 may be omitted.

[0087] Furthermore, the inlet 302 of the drainage channel 301 is higher than the outlet 303, allowing the liquid in the drainage channel 301 to be discharged by gravity. Provided that the outlet 303 is lower than the inlet 302 and the entire drainage channel 301 can drain by gravity, the outlet 303 can be located at any position on the housing 100, allowing the liquid to be discharged from the outlet 303 to the outside of the housing 100. In some embodiments, the inlet 302 is located at the top of the housing 100 (e.g., on the panel 110), and the outlet 303 can be located on the bottom wall of the housing 100, thereby guiding the liquid to flow out towards the bottom wall of the housing 100. In some embodiments, the outlet 303 can also be located on the side of the housing 100 or at other positions.

[0088] Please refer to Figure 4 and 9 In some embodiments, the housing 100 has a bottom shell 120 disposed opposite to the panel 110, the bottom shell 120 and the panel 110 being used to form a mounting cavity 101. The bottom shell 120 has a liquid outlet 303, and a third gap 306 communicates with the liquid outlet 303 to guide liquid to flow to the liquid outlet 303.

[0089] Please refer to Figure 4 and 9 In some embodiments, the bottom shell 120 has a bottom shell wall 121 with a disassembly port. A liquid outlet shell 122 is mounted on the disassembly port, and the liquid outlet shell 122 has a liquid outlet 303 communicating with the third gap 306. The liquid outlet shell 122 is fixedly connected to the bottom shell wall 121. This disassembly and assembly structure facilitates manufacturing and reduces manufacturing difficulty. The liquid outlet shell 122 can be fixedly connected to the bottom shell wall 121. This fixed connection can be a detachable fixed connection such as a snap-fit, or it can be an adhesive, weld, or other fixed structure.

[0090] Furthermore, in some embodiments, the panel 110 may be made of materials such as glass or ceramic. For details on how the temperature sensing component 200 can be installed, please refer to... Figure 1 and 2In some embodiments, the panel 110 is provided with a first through hole 111. Once the first through hole 111 is provided, the impact resistance of the panel 110 will decrease and become brittle, forming numerous cracks. This allows liquid (or other conductive media) to easily enter the mounting cavity 101 inside the device from the panel 110, causing the device to fail or become dangerous.

[0091] Please refer to Figure 1-6 In some embodiments, the induction cooker 1 further includes a waterproof layer 400. The waterproof layer 400 is located inside the panel 110 and has a second through hole 410. The waterproof layer 400 is sealed and fixed to the panel 110 on all sides, including direct fixed connection and indirect fixed connection through other structures. The support base 220 is sealed and fixedly connected to the waterproof layer 400. One end of the temperature sensing component 200 passes through the second through hole 410 and the first through hole 111 and extends outside the panel 110. When the panel 110 cracks, liquid will flow downwards through the crack. At this time, the waterproof layer 400 can block the liquid between the waterproof layer 400 and the panel 110, preventing it from flowing into the mounting cavity 101. The support base 220 and the waterproof layer 400, as well as the waterproof layer 400 and the panel 110, can be fixedly connected by adhesive, welding, snap-fit, screwing, or other methods. To achieve or enhance the sealing effect, a sealing element can also be provided between the support base 220 and the panel 110 to improve the sealing effect.

[0092] In some embodiments, the waterproof layer 400 may also be made of a heat-insulating material, so that the waterproof layer 400 can serve a heat-insulating function in addition to waterproofing. For example, the waterproof layer 400 may be made of mica sheet.

[0093] To prevent liquid between the waterproof layer 400 and the panel 110 from entering the drainage channel 301, please refer to... Figure 4-6 In some embodiments, a sealed cavity 500 is formed between the waterproof layer 400, the support base 220, and the panel 110. The mounting cavity 101 is located below the waterproof layer 400, and the heating component is disposed in the mounting cavity 101. The gas in the sealed cavity 500 does not flow with the outside, thus forming a thermal insulation structure between the heating component and the panel 110, thereby preventing the panel 110 from overheating and causing danger.

[0094] Please refer to Figure 4 In some embodiments, the connecting portion 2221 is located between the panel 110 and the waterproof layer 400, and the side of the connecting portion 2221 facing away from the panel 110 is sealed and fixed to the waterproof layer 400, so that a sealed cavity 500 is formed between the waterproof layer 400 and the panel 110. In other embodiments, in order to form the sealed cavity 500, the waterproof layer 400 may also be connected to the side of the connecting portion 2221 facing the panel 110 or to other positions of the connecting portion 2221.

[0095] In other embodiments, the waterproof layer 400, the support base 220, and the panel 110 may not form a sealed cavity 500. The connecting portion 2221 and the side of the waterproof layer 400 facing the panel 110 both have drainage gaps with the panel 110. These drainage gaps communicate with drainage channels 301 (such as the second gap 305) to allow liquid in the drainage gaps to drain through the drainage channels 301. Specifically, if the panel 110 breaks, liquid entering from the panel 110 can flow from the drainage gaps into the drainage channels 301, preventing liquid from accumulating between the waterproof layer 400 and the panel 110.

[0096] The waterproof layer 400 can be directly sealed to the panel 110, or it can be indirectly sealed through other structures. Please refer to [reference needed]. Figure 1 , 2 In some embodiments, such as 5 and 6, the housing 100 further includes a support frame 130 mounted on the bottom housing 120, with the panel 110 supported on the support frame 130. The support frame 130 has a panel support portion 131 and a waterproof layer support portion 132. The panel 110 is fixedly mounted on the panel support portion 131, and the waterproof layer 400 is fixedly mounted on the waterproof layer support portion 132. The panel 110 and the panel support portion 131, as well as the waterproof layer 400 and the waterproof layer support portion 132, can be fixedly connected by adhesive, welding, or other methods. Adhesive and welding not only achieve a fixed connection but also provide a waterproof effect. To achieve or enhance the sealing effect, sealing elements can also be provided between the panel 110 and the support frame 130, and between the waterproof layer 400 and the support frame 130, to improve the sealing effect.

[0097] Please refer to Figure 2 , 4 In some embodiments, 5 and 6, the panel 110 and the panel support 131, as well as the waterproof layer 400 and the waterproof layer support 132, are overlapped to prevent liquid from flowing into the mounting cavity 101 through the gap between the panel 110 and the panel support 131. In some embodiments, the panel 110 and the temperature sensing component 200 are overlapped to prevent liquid from flowing into the mounting cavity 101 through the gap between the panel 110 and the temperature sensing component 200. In some embodiments, the waterproof layer 400 and the temperature sensing component 200 are also overlapped to prevent liquid from flowing into the mounting cavity 101 through the gap between the waterproof layer 400 and the temperature sensing component 200.

[0098] Furthermore, in some embodiments, the temperature sensing component 200 is typically fixedly mounted on the base housing 120. During assembly, the temperature sensing component 200 is first fixed to the base housing 120, and then the first through hole 111 on the panel 110 is fitted onto the temperature sensing head 210 of the temperature sensing component 200. In this assembly process, fitting the panel 110 onto the temperature sensing component 200 relies solely on experience and prediction for blind assembly, resulting in low production efficiency. For further details, please refer to... Figure 4 and 9 In some embodiments, the temperature measuring component 200 is fixedly connected to the panel 110 or the waterproof layer 400 through the upper end of the support base 220. Therefore, during assembly, the temperature measuring component 200 can be fixed to the panel 110 first, and then the panel 110 and the temperature measuring component 200 can be installed together on the base shell 120 or the support frame 130 to avoid blind installation and improve assembly efficiency.

[0099] In some embodiments, since the temperature sensing component 200 is fixed to the panel 110 or the waterproof layer 400, the lower end of the support base 220 can be separated from, abutted against, or non-fixedly connected to the bottom shell 120 to reduce assembly difficulty.

[0100] In some embodiments, please refer to Figure 1 and 2 The housing 100 may also have a display area panel 140, which is located above the display screen to protect it. Of course, in some embodiments, the display area panel 140 may be omitted, and no display screen is provided.

[0101] The above description uses an induction cooker 1 as an example to illustrate the structure of the cooking heating device. In other embodiments, the cooking heating device may also adopt other structures, such as the heating component being located on the outside of the panel 110, as in a gas stove where the heating component is located on the panel 110.

[0102] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
