Description

Technical Field

[0001] This application relates to the field of cooking utensil technology, and more particularly to a cooking utensil. Background Technology

[0002] This section is intended to provide background or context for embodiments of this application. The description herein is not intended to imply that it is prior art simply because it is included in this section.

[0003] The cooking appliance includes a cooktop and a coil. The cooktop is used to place other cooking equipment such as pots and pans, and the coil includes a communication coil that enables communication.

[0004] In related technologies, the communication coil has multiple solder points, and the cooktop panel is usually placed against these solder points, which can scratch the cooktop panel. In other cases, during cooking, the water in the pot gradually decreases or even disappears, causing the pot to heat up and dry out, reaching temperatures far exceeding those when it was filled with water. The heat generated by the pot is transferred to the communication coil via the cooktop panel, which can easily cause the solder points to melt. Utility Model Content

[0005] In view of this, the present application aims to provide a cooking appliance that can reduce the risk of weld points melting and, to a certain extent, prevent weld points from scratching the stove panel.

[0006] This application provides a cooking appliance, including:

[0007] Stove panel;

[0008] A wireless communication coil is disposed on the back side of the cooktop panel, the wireless communication coil comprising:

[0009] Thermal insulation structure;

[0010] A communication winding, at least a portion of which is located on the back side of the thermal insulation structure, the communication winding having a plurality of solder joints, all of which are located on the back side of the thermal insulation structure.

[0011] In some embodiments, the heat insulation structure has multiple through holes, and the communication winding includes a first winding and a second winding. A portion of the first winding and a portion of the second winding are located on the front side of the heat insulation structure, while another portion of the first winding and another portion of the second winding extend through the through holes to the back side of the heat insulation structure and are welded at the welding point.

[0012] In some embodiments, the welding point at the beginning of both the first winding and the second winding is the first welding point, and the welding point at the end of both the first winding and the second winding is the second welding point, with the first welding point and the second welding point being radially spaced apart.

[0013] In some embodiments, all of the communication windings are located on the back side of the thermal insulation structure.

[0014] In some embodiments, the cooking appliance includes an insulating element, and the communication winding includes a first winding and a second winding. The first winding has a first stacked section and a first spread section, and the second winding has a second stacked section and a second spread section. The outer periphery of the first stacked section and the outer periphery of the second stacked section both wrap around the insulating element. The first stacked section and the second stacked section are stacked in a front-back direction, and the first spread section and the second spread section are both spread on the back side of the heat insulation structure.

[0015] In some embodiments, the cooking appliance includes a base, the base including a power supply coil disposed on the side of the wireless communication coil away from the cooktop panel.

[0016] In some embodiments, the substrate includes a flange, and the thermal insulation structure is disposed on the side of the flange away from the power supply coil.

[0017] In some embodiments, the distance between the communication winding and the power supply coil is not less than 3 mm.

[0041] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0042] In the description of the embodiments of this application, the "front and back directions" orientation or positional relationship is based on Figure 4 , Figure 7 , Figure 10 The orientation or positional relationship shown is for illustrative purposes only and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the embodiments of this application.

[0043] The various specific technical features and embodiments described in the detailed embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features / embodiments can form different implementation methods. To avoid unnecessary repetition, the various possible combinations of various specific technical features / embodiments in this application will not be described separately. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] It should be noted that in this application, the length unit "mm" refers to millimeters. The temperature unit "℃" refers to degrees Celsius. "Multiple" refers to a quantity of two or more.

[0045] For related technologies, please refer to Figure 1 and Figure 2 The cooking appliance includes a heat insulation layer 4', solder joints 3', and part of the communication coil 2' located on the side of the heat insulation layer 4' closer to the cooktop panel 1', while the other part of the communication coil 2' is located on the side of the heat insulation layer 4' away from the cooktop panel 1'. In some cases, an additional heat insulation layer 4' is installed between the solder joint 3' and the cooktop panel 1'. While this can prevent heat from being transferred to the solder joint 3' when the cookware is dry-heated, it increases the distance between the communication coil 2' and the cookware, affecting the communication distance and increasing costs.

[0046] Please see Figures 3 to 11 This application provides a cooking appliance, including a cooktop panel 1 and a wireless communication coil plate 2. The cooktop panel 1 is used to place cooking equipment such as pots and pans. Please refer to... Figure 3 and Figure 4The cooktop panel 1 is roughly plate-shaped, and its surface is flat, allowing cooking equipment to be placed stably on it.

[0047] The wireless communication coil 2 is disposed on the back side of the stove panel 1. The wireless communication coil 2 includes a heat insulation structure 21 and a communication winding 22. At least a portion of the communication winding 22 is located on the back side of the heat insulation structure 21. The communication winding 22 has multiple solder points 22a, all of which are located on the back side of the heat insulation structure 21.

[0048] It should be noted that the front side is the side where the exterior surface of the stove panel 1 is located, and the back side is the opposite of the front side. The back side is the side of the stove panel 1 that is away from the exterior surface. When the cooking utensils are assembled and in use, the exterior surface faces upward, the front side is the upper side of the stove panel 1, and the back side is the lower side of the stove panel 1.

[0049] The heat insulation structure 21 refers to a structure made of high-temperature resistant materials. This means that the heat insulation structure 21 can maintain its physical and chemical properties at high temperatures. For example, the heat insulation structure 21 can withstand temperatures of 235°C and above, meaning it will not deform at temperatures of 235°C and above. Thus, the heat insulation structure 21 has good high-temperature resistance. The communication winding 22 refers to a coil or coil group that achieves data transmission through electromagnetic coupling, thereby realizing communication functionality.

[0050] The specific type of the communication winding 22 is not limited. For example, the communication winding 22 can be enameled wire, that is, the outer surface of the communication winding 22 is coated with an insulating coating. In this way, the communication winding 22 can ensure good insulation performance in both normal temperature and high temperature environments, preventing problems such as short circuits and leakage.

[0051] Please see Figures 5 to 8 At least a portion of the communication winding 22 is located on the back side of the heat insulation structure 21, and all welding points 22a are located on the back side of the heat insulation structure 21. That is, at least a portion of the communication winding 22 is located on the side of the heat insulation structure 21 away from the cooktop panel 1, and all welding points 22a are located on the side of the heat insulation structure 21 away from the cooktop panel 1. In this way, on the one hand, the welding points 22a are separated from the cooktop panel 1 by the heat insulation structure 21, and the welding points 22a do not contact the cooktop panel 1, thereby preventing the welding points 22a from scratching the cooktop panel 1. On the other hand, during the operation of the cooking appliance, when the pot becomes dry-heated, the heat insulation structure 21 does not deform, thereby blocking some heat transfer to the back side and preventing the welding points 22a from melting at high temperatures. Furthermore, compared to related technologies, this application only sets up one heat insulation structure 21, which can achieve a better heat insulation effect without affecting the communication distance, protecting the welding points 22a from melting and reducing production costs.

[0052] In the cooking appliance provided in this application embodiment, all welding points 22a and at least a portion of the communication winding 22 are located on the side of the heat insulation structure 21 away from the stove panel 1. On the one hand, the welding points 22a are separated from the stove panel 1 by the heat insulation structure 21, and the welding points 22a do not contact the stove panel 1, thereby preventing the welding points 22a from scratching the stove panel 1. On the other hand, during the operation of the cooking appliance, when the pot becomes dry-heated, the heat insulation structure 21 does not deform, thereby blocking some heat transfer to the back side and preventing the welding points 22a from melting at high temperatures. Furthermore, compared with related technologies, this application only sets up one heat insulation structure 21, which can achieve a better heat insulation effect without affecting the communication distance, protecting the welding points 22a from melting and reducing production costs.

[0053] In one embodiment, the heat insulation structure 21 is a mica sheet. Thus, the heat insulation structure 21 has both good insulation performance and heat resistance performance.

[0054] In one embodiment, the cooktop panel 1 can be a glass plate.

[0055] The wireless communication coil 2 provided in this embodiment has near-field communication (NFC) functionality. NFC is a short-range wireless communication method based on contactless radio frequency identification (RFID) technology. Without requiring an external power source, the communication winding 22 can interact with an induction coil that has a compatible NFC protocol, which is convenient and fast. Both the communication winding 22 and the induction coil operate at the same frequency.

[0056] In some embodiments, please refer to Figure 4 The cooking appliance includes a base 3, which includes a power supply coil 31. The power supply coil 31 is spaced apart on the side of the communication winding 22 away from the heat insulation structure 21. In other words, the cooking appliance has an electromagnetic heating function. Specifically, when a high-frequency current is applied to the power supply coil 31, it can generate an electromagnetic field. During the operation of the cooking appliance, if a magnetic cooking device is placed above the cooktop 1, the magnetic cooking device will resonate in the electromagnetic field and generate eddy currents. Under the action of the eddy currents, the magnetic cooking device will gradually heat up and cook food through the high-temperature magnetic cooking device.

[0057] The specific type of cooking appliance is not limited; for example, the cooking appliance may be an induction cooker or an induction stove.

[0058] For example, the communication winding 22 can function as a receiver. When an external device, such as a cooking appliance, is placed on the cooktop 1, the communication winding 22 receives a signal indicating that the cooking appliance has been placed and sends this signal to the power supply coil 31. Current is then passed through the power supply coil 31 to generate a magnetic field, causing the cooking appliance to heat up. For example, the communication winding 22 can function as a transmitter. When an external device, such as a mobile terminal, approaches the cooking appliance, the communication winding 22 can send signals containing various cooking modes to the mobile terminal. This allows users to select different cooking modes based on the ingredients, improving the user experience. For example, the communication winding 22 can function as a transceiver; that is, the communication winding 22 can both receive and transmit signals.

[0059] In some embodiments, the heat insulation structure 21 has multiple through holes, and the communication winding 22 includes a first winding 221 and a second winding 222. A portion of the first winding 221 and a portion of the second winding 222 are located on the front side of the heat insulation structure 21, while another portion of the first winding 221 and another portion of the second winding 222 extend through the through holes to the back side of the heat insulation structure 21 and are welded at welding point 22a. Specifically, the first winding 221 and the second winding 222 are electrically connected. A portion of the first winding 221 and a portion of the second winding 222 are located on the side of the heat insulation structure 21 closest to the cooktop panel 1 along the front-back direction. Thus, when a pot or mobile terminal is placed on the cooktop panel 1 and close to the cooking appliance, the communication distance between this portion of the communication winding 22 and the pot or mobile terminal is relatively short, enabling rapid sensing and information interaction.

[0060] Please refer to 4 to Figure 6 The other part of the first winding 221 and the other part of the second winding 222 are welded at the welding point 22a on the side of the heat insulation structure 21 away from the stove panel 1. That is, all welding points 22a are located on the same side of the heat insulation structure 21 along the front and back directions. In this way, during the assembly process, there is no need to flip the heat insulation structure 21 back and forth, which makes it easier for operators to weld the first winding 221 and the second winding 222 and improves production efficiency.

[0061] In some embodiments, please refer to Figure 3 , Figure 5 and Figure 6 The welding point 22a at the beginning of the first winding 221 and the second winding 222 is the first welding point 22a1, and the welding point at the end of the first winding 221 and the second winding 222 is the second welding point 22a2. The first welding point 22a1 and the second welding point 22a2 are separated from each other radially.

[0062] For example, the through holes located on opposite radial sides of the first welding point 22a1 are called first through holes, and the through hole near the second welding point 22a2 is called a second through hole. The starting ends of both the first winding 221 and the second winding 222 are welded at the first welding point 22a1. Both the first winding 221 and the second winding 222 extend spirally outward from the first welding point 22a1 in opposite directions, and pass through the two first through holes to reach the front side of the heat insulation structure 21. The first winding 221 and the second winding 222 then extend radially inward from the two first through holes, and when they reach the area around the first welding point 22a1, they extend radially outward in parallel, and pass through the two second through holes to reach the back side of the heat insulation structure 21. Thus, the tail ends of the first winding 221 and the second winding 222 are welded at the second welding point 22a2.

[0063] In other embodiments, the first winding 221 and the second winding 222 respectively pass through two first through holes to extend to the front side of the heat insulation structure 21, and both extend circumferentially to the second through holes, respectively passing through two second through holes to extend to the back side of the heat insulation structure 21. Thus, the tail ends of the first winding 221 and the second winding 222 are welded at the second welding point 22a2. This saves materials and reduces production costs.

[0064] It should be noted that the radial direction is perpendicular to the front and back directions. The radial direction is the direction of the ray passing through the center line of the thermal insulation structure 21 in a plane perpendicular to the front and back directions. The inner direction refers to the side closer to the center line in the radial direction, while the outer direction is the opposite direction to the inner direction, and the outer direction refers to the side farther away from the center line in the radial direction.

[0065] In some embodiments, please refer to Figure 7 and Figure 8 The welding surface of welding point 22a faces the back side. That is, the welding surface is located on the side of welding point 22a away from the heat insulation structure 21 along the front-back direction. This facilitates welding of the first winding 221 and the second winding 222 by the operator, reducing the difficulty of the operation. For example, the welding surface of the first welding point 22a1 faces the back side. Another example is the welding surface of the second welding point 22a2 facing the back side. Yet another example is that the welding surfaces of both the first welding point 22a1 and the second welding point 22a2 face the back side.

[0066] In some embodiments, please refer to Figures 9 to 11 All communication windings 22 are located on the back side of the heat insulation structure 21. That is, all communication windings 22 are located on the side of the heat insulation structure 21 away from the cooktop panel 1 along the front-back direction. In this way, during the operation of the cooking appliance, when the pot becomes dry-burned, the heat insulation structure 21 does not deform, thereby blocking some heat from being transferred to the back side, preventing the communication windings 22 from burning out, and ensuring the operational reliability of the communication windings 22.

[0067] In some embodiments, please refer to Figure 9 The cooking appliance includes an insulating component. The first winding 221 has a first stacked section 2211 and a first spread section 2212. The second winding 222 has a second stacked section 2221 and a second spread section 2222. The outer periphery of the first stacked section 2211 and the outer periphery of the second stacked section 2221 are both wrapped with an insulating component. The first stacked section 2211 and the second stacked section 2221 are stacked in the front-back direction. The first spread section 2212 and the second spread section 2222 are both spread on the back side of the heat insulation structure 21.

[0068] Insulating components are structures made of insulating materials that can provide insulation.

[0069] For example, the first end of the first stacked segment 2211 and the last end of the first spreading segment 2212 are connected, and the first end of the second stacked segment 2221 and the last end of the second spreading segment 2222 are connected. The first end of the first spreading segment 2212 is the first end of the first winding 221, and the first end of the second spreading segment 2222 is the first end of the second winding 222. The welding point 22a at the first ends of the first spreading segment 2212 and the second spreading segment 2222 is the first welding point 22a1. The last end of the first stacked segment 2211 is the last end of the first winding 221, and the last end of the second stacked segment 2221 is the last end of the second winding 222. The welding point 22a at the last ends of the first stacked segment 2211 and the second stacked segment 2221 is the second welding point 22a2.

[0070] Thus, on the one hand, the first stacking segment 2211 and the second stacking segment 2221 are stacked in the opposite direction, which saves space and provides more wiring space for the first spreading segment 2212 and the second spreading segment 2222, making the first winding 221 and the second winding 222 neatly arranged and avoiding tangling. On the other hand, the outer periphery of the first stacking segment 2211 and the outer periphery of the second stacking segment 2221 are respectively wrapped with insulating materials, which not only prevents the first stacking segment 2211 and the second stacking segment 2221 from scratching each other and causing wear, but also reduces electromagnetic interference and ensures the stability of signal transmission. Furthermore, the heat insulation structure 21 reduces the heat transferred to the first spreading segment 2212 and the second spreading segment 2222, preventing the first spreading segment 2212 and the second spreading segment 2222 from being burned by high temperature when the cookware is dry-burned, thus ensuring the operational reliability of the communication winding 22.

[0071] The stacking of the first stacked segment 2211 and the second stacked segment 2221 along the front-back direction means that, with a plane perpendicular to the front-back direction as the projection plane, at least part of the projections of the first stacked segment 2211 and the second stacked segment 2221 overlap. For example, the projections of the first stacked segment 2211 and the second stacked segment 2221 may completely overlap. Alternatively, the projections of the first stacked segment 2211 and the second stacked segment 2221 may not completely overlap.

[0072] In one embodiment, both the first stacked segment 2211 and the second stacked segment 2221 are located on the back side of the heat insulation structure 21. That is, both the first stacked segment 2211 and the second stacked segment 2221 are located on the side of the heat insulation structure 21 away from the cooktop panel 1.

[0073] In some embodiments, please refer to Figure 7 and Figure 10 The power supply coil 31 is located on the side of the wireless communication coil 2 away from the cooktop panel 1. Please refer to the following: Figure 7 and Figure 10 The communication winding 22 and the power supply coil 31 are spaced apart along the front-back direction. That is, the power supply coil 31 is located on the back side of the heat insulation structure 21. Thus, on the one hand, the spaced arrangement of the communication winding 22 and the power supply coil 31 ensures a sufficiently safe electrical clearance between them, preventing problems such as arcing and short circuits. On the other hand, the heat insulation structure 21 reduces the heat transferred to the power supply coil 31, preventing it from burning out due to high temperatures when the cookware is dry-burning, thus ensuring the operational reliability of the power supply coil 31.

[0074] In some embodiments, please refer to Figure 7 and Figure 10 The substrate 3 includes a flange 32, and a heat insulation structure 21 is disposed on the side of the flange 32 away from the power supply coil 31. Specifically, the heat insulation structure 21 is stacked on the flange 32. In this way, the flange 32 provides support for the heat insulation structure 21 to maintain the stability of the heat insulation structure 21.

[0075] In one embodiment, the substrate 3 includes a housing, a power supply coil 31 is disposed inside the housing, and a flange 32 is disposed on the housing. The housing can prevent the power supply coil 31 from contacting water or impurities, thus providing good protection.

[0076] In some embodiments, please refer to Figure 8 and Figure 11 The distance between the communication winding 22 and the power supply coil 31 shall not be less than 3mm. For example, the distance between the communication winding 22 and the power supply coil 31 can be 3mm, 3.2mm, 3.4mm, 3.6mm, 3.8mm, 4mm, 5mm, or 6mm, etc. By setting an appropriate spacing, the electrical clearance between the communication winding 22 and the power supply coil 31 can be ensured to meet the requirements, preventing problems such as arcing and short circuits.

[0077] In some embodiments, please refer to Figure 3 and Figure 9The communication winding 22 is double-helixed. That is, the communication winding 22 comprises two helical coils. This allows the magnetic fields generated by the communication winding 22 to superimpose at its center, significantly improving signal strength. Furthermore, it allows for an increase in the length of the communication winding 22 within a limited area while maintaining the inter-turn spacing, which is beneficial for insulation protection and heat dissipation. In addition, it reduces the number of bends in the communication winding 22, thereby extending its service life.

[0078] In one embodiment, please refer to Figure 3 and Figure 9 The first spreading segment 2212 and the second spreading segment 2222 together form a double helix. For example, the first spreading segment 2212 and the second spreading segment 2222 extend spirally from the first welding point 22a1 to opposite sides and then outward, that is, the first spreading segment 2212 and the second spreading segment 2222 are arranged in an alternating spiral pattern.

[0079] In one embodiment, the first spreading segment 2212 and the second spreading segment 2222 rotate in the same direction. See also... Figure 9 Both the first spreading segment 2212 and the second spreading segment 2222 can rotate clockwise. Both the first spreading segment 2212 and the second spreading segment 2222 can also rotate counterclockwise.

[0080] In some embodiments, the cooking appliance includes an adhesive structure that bonds the communication winding 22 and the heat insulation structure 21. This enhances the stability of the connection between the communication winding 22 and the heat insulation structure 21. Furthermore, the shape and position of the communication winding 22, connected by adhesive bonding, remain essentially unchanged, ensuring that the winding spacing of the communication winding 22 meets requirements, thereby reducing signal interference and improving the operational reliability of the communication winding 22.

[0081] In one embodiment, the adhesive structure is an adhesive.

[0082] In one embodiment, the adhesive structure can be a high-temperature resistant adhesive, which is an adhesive that can maintain good performance in high-temperature environments. For example, the adhesive structure can withstand temperatures of 235°C and above, meaning that the adhesive structure does not deform at temperatures of 235°C and above. Thus, the adhesive structure can still maintain good bonding performance in high-temperature environments.
