Description
Technical Field
[0001] This application relates to the field of kitchen appliance technology, and in particular to a base structure and cooking utensil. Background Technology
[0002] Currently, cooking appliances have a temperature sensor on the base to detect the pot's temperature. Part of this sensor is exposed for direct contact with the pot to ensure accurate temperature measurement. However, this very design allows liquids left over from cooking or washing to come into contact with the sensor. Under the influence of gravity and surface tension, this liquid can spread down the sensor's leads, potentially causing short circuits and other malfunctions. This not only affects the normal use of the cooking appliance but also poses a significant safety hazard. Utility Model Content
[0003] Therefore, it is necessary to provide a base structure that can effectively prevent water from spreading from the outer wall of the temperature sensing component to the lead wire, facilitate rapid and timely drainage, significantly improve waterproof reliability, and thus reduce safety hazards.
[0004] A base structure includes a coil disk, a temperature measuring component, and a supporting middle plate. The coil disk has an assembly cavity, and the bottom of the assembly cavity has a wiring hole. The temperature measuring component is movably disposed in the assembly cavity, and the lead wire of the temperature measuring component passes through the wiring hole. The supporting middle plate is disposed above the coil disk and has a through hole for the temperature measuring component to pass through. There is an assembly gap between the wall of the through hole and the outer wall of the temperature measuring component. The portion of the temperature measuring component below the through hole has a downwardly protruding first baffle, and the edge of the wiring hole has an upwardly protruding second baffle. The assembly cavity, the first baffle, and the second baffle are arranged sequentially from the outside to the inside along the vertical direction. The bottom of the assembly cavity also has a water leakage channel located on the outer periphery of the second baffle, and the cross-sectional area of the water leakage channel is not less than the cross-sectional area of the assembly gap.
[0005] Understandably, the outer wall of the second baffle and the cavity wall of the mounting cavity together form an annular water-retaining area around the wiring hole, with the first baffle located within the corresponding area of the annular water-retaining area. Therefore, the liquid drained by the first baffle can drip directly into the annular water-retaining area, preventing it from spreading along the temperature sensing component to the lead wire and improving waterproofing. Furthermore, the mounting cavity is positioned on the coil disc to ensure the stability of the annular water-retaining area and prevent liquid splashing caused by the movement of the temperature sensing component. Simultaneously, the mounting cavity also has a drainage channel on the outer side of the second baffle, which is equivalent to having a drainage channel corresponding to the annular water-retaining area. This facilitates the drainage of liquid remaining in the annular water-retaining area along the drainage channel to the bottom of the coil disc. Moreover, the difference in cross-sectional area between the drainage channel and the mounting gap reduces the risk of lead wire wetting due to excessive water accumulation in the annular water-retaining area, allowing for rapid and timely drainage and significantly improving waterproofing reliability.
[0006] In some embodiments, the diameter of the through hole is d1, the outer diameter of the temperature sensing component is d2, and the cross-sectional area S of the water leakage channel satisfies:
[0007] .
[0008] This setup further improves drainage efficiency, preventing problems such as overflow due to excessive water flow or water accumulation due to poor water flow.
[0009] In some embodiments, the assembly cavity has a first wire clamping part on the side opposite to the temperature measuring component, and the first wire clamping part and the water leakage channel are arranged circumferentially at intervals along the wiring hole.
[0010] Understandably, the first wire clamp is used to limit the lead wire and avoid messy wiring; and, due to the spacing between the first wire clamp and the water leakage channel, the lead wire will not approach the water leakage channel in the wiring direction, further reducing the risk of contact and improving waterproof performance.
[0011] In some embodiments, the central angle between the central axis of the first locking wire portion and the central axis of the leakage channel is between 60° and 180°.
[0012] In other words, by limiting the distance between the first locking part and the leakage channel, the lead wire is effectively prevented from coming into contact with the liquid, thus significantly improving the waterproof effect.
[0013] In some embodiments, the first wire-locking portion includes a first rib and a second rib, both of which protrude from the bottom of the assembly cavity. The first rib and the second rib are arranged at intervals along the circumference of the wire routing hole and together form a wire-locking groove.
[0014] In other words, the wire-locking groove between the first and second ribs is used to limit the offset of the lead wire along the circumference of the coil and guide the wire routing.
[0015] In some embodiments, the distance between the first rib and the second rib is between 5 mm and 20 mm.
[0016] In this way, the spacing between the first and second ribs can be kept as close as possible to the lead diameter, which can reduce the lead deformation while satisfying the snap-fit limit and maintaining normal signal transmission.
[0017] In some embodiments, the coil disc has a second wire-clamping portion on the side opposite to the supporting middle plate, and the second wire-clamping portion and the first wire-clamping portion are arranged radially spaced along the wire routing hole.
[0018] This design improves the reliability of the lead assembly and ensures that the lead is kept away from the leakage channel in the routing direction; moreover, this design allows the lead to be led out from the wiring hole to the power board in the shortest possible distance, avoiding messy wiring.
[0019] In some embodiments, the protrusion height of the second baffle is not less than 5mm.
[0020] In this way, while satisfying the water-blocking function of the second baffle, the movement restrictions on the temperature measuring components are reduced.
[0021] In some embodiments, the end face of the assembly cavity, the extended end of the first baffle, and the extended end of the second baffle are arranged in a staggered manner from high to low in the vertical direction.
[0022] This design allows at least a portion of the first baffle to extend into the assembly cavity, facilitating a smoother and more complete flow of liquid along the first baffle into the assembly cavity. Furthermore, the cooperation between the first and second baffles ensures water blocking while preventing interference with the vertical displacement of the temperature measuring component.
[0023] In some embodiments, the supporting plate has a supporting rib protruding downward around the outer periphery of the through hole, and the supporting rib can abut against the side of the first baffle away from the second baffle.
[0024] In other words, the contact between the first baffle and the support rib is used to limit the upward displacement of the temperature measuring component and maintain its reliable use.
[0025] In some embodiments, the coil includes a support plate and an annular enclosure, the support plate being connected to the outer periphery of the annular enclosure, the annular enclosure forming the assembly cavity; the support plate has a fourth baffle protruding downward around the periphery of the through hole, the fourth baffle surrounding the outer periphery of the support baffle, and the projections of the fourth baffle and the annular enclosure in the vertical direction have overlapping areas.
[0026] Understandably, by using the cooperation of the fourth baffle and the annular enclosure, the opening of the assembly cavity is blocked, preventing liquid from flowing out of the assembly cavity and minimizing the spread of liquid to other parts of the coil, thus further improving the water-blocking effect.
[0027] In some embodiments, the leakage channel includes a through-hole located at the bottom of the assembly cavity and a third baffle located at the bottom edge of the through-hole, the third baffle protruding downwards.
[0028] In other words, the third baffle also guides the liquid flowing through the drain hole, thereby reducing the risk of the liquid spreading along the bottom of the assembly cavity to other parts of the coil under its tension, and keeping the liquid as close to the bottom as possible.
[0029] In some embodiments, the base structure further includes a base body, the supporting middle plate is connected to the base body and together they form an assembly cavity, and the coil is disposed in the assembly cavity; wherein, the bottom of the base body is provided with a water outlet corresponding to the position of the water leakage channel, and the base body is provided with a fifth baffle rib protruding on the side of the water outlet near the functional device.
[0030] In other words, the liquid drained through the leakage channel can drip to the outlet and be discharged from the outlet; and, with the fifth baffle, the liquid dripping to the outlet can be prevented from flowing to the functional components and causing malfunctions, thus reducing safety hazards.
[0031] In some embodiments, the temperature measuring assembly includes a mounting base and a temperature measuring element disposed on the mounting base, the lead wire is connected to the temperature measuring element, and the first baffle protrudes from the edge of the mounting base or near the edge; wherein, the mounting base is provided with a downwardly protruding limiting rib, the limiting rib is located inside the first baffle rib, and the limiting rib can abut against the second baffle rib.
[0032] In other words, the downward displacement of the temperature measuring component is limited by the contact between the limiting rib and the second baffle rib; and since the limiting rib is located on the outside of the first baffle rib, it will not interfere with the water-blocking effect of the first baffle rib.
[0033] This application also provides a cooking appliance, including a pot body and the aforementioned base structure, wherein the pot body is supported on a supporting plate of the base structure, and the temperature measuring component is capable of contacting the bottom of the pot body.
[0034] Because of the aforementioned base structure, this cooking appliance can drain liquid that drips onto the temperature sensing component, preventing the liquid from coming into contact with the lead wire of the temperature sensing component and reducing safety hazards.

The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0053] In related technologies, taking electromagnetically heated cooking appliances as an example, the base contains a coil disc and a coil mounted on the coil disc. The coil is electrically connected to a power board within the base. Simultaneously, the base also includes a temperature sensing component for detecting the pot's temperature. The lead wire of the temperature sensing component is electrically connected to the power board to transmit a detection signal, facilitating timely adjustment of the heating power. To ensure accurate temperature measurement by the temperature sensing component, a through-hole is typically provided in the base for the component to pass through, allowing direct contact between the component and the pot.
[0054] However, because this through-hole exposes the top of the temperature sensing component, liquid overflowing from the pot during cooking, residual liquid after washing the pot, or accidental drips during use can all come into contact with the temperature sensing component. Under the influence of gravity and surface tension, this liquid can spread downwards along the temperature sensing component's leads, potentially causing short circuits and other malfunctions. This not only affects the normal use of the cooking appliance but also poses a significant safety hazard.
[0055] To address this, one embodiment of this application provides a base structure that effectively prevents water from spreading from the outer wall of the temperature sensing component to the lead wire, facilitates rapid and timely drainage, significantly improves waterproof reliability, and thus reduces safety hazards. The base structure is described in detail below.
[0056] Please see Figures 1 to 3One embodiment of this application provides a base structure 100, including a coil disk 120, a temperature measuring component 130, and a supporting middle plate 110. The coil disk 120 has a mounting cavity 1201, and the bottom of the mounting cavity 1201 has a wiring hole 1202. The temperature measuring component 130 is movably disposed in the mounting cavity 1201, and the lead wire 133 of the temperature measuring component 130 passes through the wiring hole 1202. The supporting middle plate 110 is disposed above the coil disk 120 and has a through hole 1101 for the temperature measuring component 130 to pass through. There is a mounting gap 1002 between the wall of the through hole 1101 and the outer wall of the temperature measuring component 130. The temperature measuring component 130 has a first baffle 134 protruding downwards, and a second baffle 124 protruding upwards at the edge of the wiring hole 1202. The assembly cavity 1201, the first baffle 134, and the second baffle 124 are arranged to surround each other from the outside to the inside along the vertical direction. The bottom of the assembly cavity 1201 is also provided with a water leakage channel 123 located on the outer periphery of the second baffle 124. The cross-sectional area of the water leakage channel 123 is not less than the cross-sectional area of the assembly gap 1002.
[0057] The assembly cavity 1201, the first baffle 134, and the second baffle 124 are arranged in a ring-like configuration, with their vertical projections arranged sequentially from the outside to the inside. This means that the vertical projection of the assembly cavity 1201 is greater than the vertical projection of the first baffle 134, and the projection of the first baffle 134 is located within the projection of the assembly cavity 1201. Simultaneously, the vertical projection of the first baffle 134 is greater than the vertical projection of the second baffle 124, and the projection of the second baffle 124 is located within the projection of the first baffle 134. Both the first baffle 134 and the second baffle 124 are arranged in a ring shape.
[0058] The assembly gap 1002 is designed to provide flow space for liquid to seep and spread downwards. When liquid drips and comes into contact with the top of the temperature sensing component 130, it will spread downwards through the assembly gap 1002 under the action of gravity and tension. At this time, the first baffle 134 on the temperature sensing component 130 is set to guide the liquid on the top of the temperature sensing component 130 downwards, preventing the liquid from spreading to other positions of the temperature sensing component 130 under the action of tension; and, in conjunction with the assembly cavity 1201 on the coil disk 120, it can receive the liquid guided by the first baffle 134, preventing this part of the liquid from flowing to other positions of the coil disk 120. At the same time, a second baffle 124 is protruding at the wiring hole 1202 of the assembly cavity 1201, so that it surrounds the outer periphery of the lead wire 133, preventing the liquid dripping into the assembly cavity 1201 from directly contacting the lead wire 133 and preventing the lead wire 133 from getting wet. Furthermore, the water leakage channel 123 facilitates the discharge of liquid from the assembly cavity 1201.
[0059] In other words, the outer wall of the second baffle 124 and the cavity wall of the mounting cavity 1201 together form an annular water-retaining area 1200 located around the wiring hole 1202, and the first baffle 134 is located within the corresponding range of the annular water-retaining area 1200. Therefore, the liquid drained by the first baffle 134 can drip into the annular water-retaining area 1200, thereby preventing this liquid from spreading to the lead wire 133 or other parts of the coil disc 120, thus improving the waterproof effect. Moreover, precisely because the mounting cavity 1201 is located on the coil disc 120, ensuring the stability of the annular water-retaining area 1200, and preventing liquid splashing caused by the movement of the temperature measuring component 130, further ensures the reliability of waterproofing. Meanwhile, since the assembly cavity 1201 is also provided with a water leakage channel 123 at the position outside the second baffle 124, it is equivalent to providing a water leakage channel 123 at the position corresponding to the annular water storage area 1200, so that the liquid stored in the annular water storage area 1200 can be guided along the water leakage channel 123 to the bottom of the coil disk 120.
[0060] Therefore, the cross-sectional area of the assembly gap 1002 corresponds to the inlet flow cross-sectional area, and the cross-sectional area of the leakage channel 123 corresponds to the outlet flow cross-sectional area. Thus, the inlet flow cross-sectional area is not larger than the outlet flow cross-sectional area, which facilitates the rapid and timely discharge of water collected in the annular water storage area 1200, improving drainage efficiency. This reduces the risk of the lead wire 133 becoming wet and other parts of the coil disc 120 becoming waterlogged due to excessive water accumulation in the annular water storage area 1200, significantly improving waterproof reliability and reducing safety hazards.
[0061] The assembly gap 1002 is annular, meaning that the wall of the through hole 1101 and the outer wall of the temperature measuring component 130 are both smooth to reduce bumps and wear.
[0062] like Figure 3 As shown, in some embodiments, the diameter of the through hole 1101 is d1, and the outer diameter of the temperature sensing component 130 is d2. Then, the cross-sectional area S of the water leakage channel 123 satisfies:
[0063] .
[0064] This configuration ensures that the cross-sectional area of the water leakage channel 123 is greater than the cross-sectional area of the assembly gap 1002, meaning that the cross-sectional area of the inlet water flow is smaller than the cross-sectional area of the outlet water flow. Liquid flowing in through the assembly gap 1002 can be directly discharged, further improving drainage efficiency and preventing problems such as overflow due to excessive water flow or water accumulation due to poor water flow.
[0065] In some other embodiments, the cross-sectional area S of the leakage channel 123 satisfies:
[0066] .
[0067] In other words, the cross-sectional area of the leakage channel 123 is equal to the cross-sectional area of the assembly gap 1002, that is, the cross-sectional area of the water inlet flow is equal to the cross-sectional area of the water outlet flow, and the two reach a balanced state, which improves the smoothness and stability of the water flow in the process of entering and exiting.
[0068] Please see Figure 2 , Figure 4 and Figure 8 In some embodiments, the mounting cavity 1201 is provided with a first wire clamping part 125 on the side opposite to the temperature measuring component 130, and the first wire clamping part 125 and the water leakage channel 123 are arranged at intervals along the circumference of the wiring hole 1202.
[0069] In other words, the wires extending axially from the wiring hole 1202 are guided radially to the side of the coil disc 120 via the first wire clamping part 125. Furthermore, the spaced arrangement of the first wire clamping part 125 and the water leakage channel 123 ensures that the lead wire 133 will not approach the water leakage channel 123 in the wiring direction, further reducing the risk of contact and improving waterproofing performance. Moreover, because the first wire clamping part 125 is located on the outer bottom wall of the mounting cavity 1201, the radial distance between it and the wiring hole 1202 is shortened, reducing the risk of the lead wire 133 contacting liquid due to hanging at the wiring hole 1202.
[0070] The central angle between the central axis of the first wire-clamping part 125 and the central axis of the water leakage channel 123 is between 60° and 180°. In other words, the distance between the first wire-clamping part 125 and the water leakage channel 123 should not be too small; if it is too small, there is still a risk of the lead wire 133 coming into contact with the liquid. Therefore, the distance between the first wire-clamping part 125 and the water leakage channel 123 needs to be as large as possible.
[0071] like Figure 8 As shown, in some specific embodiments, the central angle between the central axis of the first wire-locking portion 125 and the central axis of the water-leaking channel 123 is 180 degrees. That is, the first wire-locking portion 125 and the water-leaking channel 123 are respectively disposed on both sides of the wiring hole 1202 along the radial direction of the wiring hole 1202. This arrangement maximizes the spacing between the first wire-locking portion 125 and the water-leaking channel 123, significantly improving the waterproofing effect.
[0072] Alternatively, the central angle of the interval between the first locking part 125 and the water leakage channel 123 can also be 60°, 80°, 100°, 120°, 150°, 170°, etc.
[0073] The first wire-catching part 125 is provided with a wire-catching groove 1253 or a wire-catching hole, etc. Therefore, the central axis of the aforementioned first wire-catching part 125 refers to the central axis of the wire-catching groove 1253 or the wire-catching hole.
[0074] like Figure 2 , Figure 4 and Figure 8 As shown, in some embodiments, the first wire-holding portion 125 includes a first rib 1251 and a second rib 1252, both of which are disposed at the bottom of the mounting cavity 1201 of the coil disk 120. The first rib 1251 and the second rib 1252 are arranged at intervals along the circumference of the wiring hole 1202 and together form a wire-holding groove 1253. That is, the wire-holding groove 1253 between the first rib 1251 and the second rib 1252 is used to limit the displacement of the lead wire 133 along the circumference of the coil disk 120 and guide the lead wire 133 to be routed radially along the wiring hole. After the lead wire 133 of the temperature measuring component 130 is led out from the wiring hole 1202, it can pass through the wire-holding groove 1253 and extend to the power board. The opposing sides of the first rib 1251 and the second rib 1252 can be rounded to ensure a smooth surface and reduce the assembly wear of the lead wire 133.
[0075] In some specific embodiments, the first rib 1251 and the second rib 1252 protrude from the outer bottom wall of the assembly cavity 1201.
[0076] like Figure 2 , Figure 4 and Figure 8 As shown, in some embodiments, the distance between the first rib 1251 and the second rib 1252 is between 5mm and 20mm. It is understood that the distance between the first rib 1251 and the second rib 1252 along the circumference of the wiring hole 1202 should not be too large or too small. If it is too large, especially larger than the diameter of the lead wire 133, it will not serve as a limiting function, causing the lead wire 133 to droop under its own weight. Of course, if it is too small, it will be difficult to snap the lead wire 133 into place, and may even cause the lead wire 133 to deform, affecting signal transmission. Therefore, the distance between the first rib 1251 and the second rib 1252 needs to be as close as possible to the diameter of the lead wire 133, satisfying the snap-in limiting function while reducing the deformation of the lead wire 133 and maintaining normal signal transmission.
[0077] In some specific embodiments, the distance between the first rib 1251 and the second rib 1252 can be 5mm, 8mm, 10mm, 12mm, 15mm, 18mm or 20mm.
[0078] like Figure 8As shown, both the first rib 1251 and the second rib 1252 are arc-shaped and extend circumferentially along the wiring hole 1202. The first rib 1251 and the second rib 1252 surround the outer periphery of the wiring hole 1202, fitting snugly and improving aesthetics. The distance between the first rib 1251 and the second rib 1252 is the distance between their approaching ends along the circumference of the wiring hole 1202.
[0079] Alternatively, both the first rib 1251 and the second rib 1252 can be elongated and parallel. In this case, the distance between them is perpendicular to the straight-line length of the first rib 1251 and the second rib 1252. Alternatively, the elongated first rib 1251 and the elongated second rib 1252 can be arranged in a trumpet shape, with the minimum distance between them being used as the standard. The goal is simply for the first rib 1251 and the second rib 1252 to together form the retaining groove 1253 for positioning; this is merely an example.
[0080] like Figure 2 and Figure 8 As shown, in actual use, the coil disc 120 has a second wire-clamping part 126 on the side opposite to the support plate 110. The second wire-clamping part 126 and the first wire-clamping part 125 are arranged radially at intervals along the wiring hole 1202. That is, by utilizing the cooperation of the first wire-clamping part 125 and the second wire-clamping part 126, the lead wire 133 is fixed and guided at multiple points in the radial direction of the wiring hole 1202, improving the assembly reliability of the lead wire 133; and, the lead wire 133 can be led out from the wiring hole 1202 to the power board through the shortest possible distance, avoiding messy wiring.
[0081] The second wire-locking part 126 can be a wire clamp, a buckle, a clamp, etc. In this case, the first protruding rib 1251 and the second protruding rib 1252 cooperate to satisfy the offset limit of the lead wire 133, and the second wire-locking part 126 is used to fix the lead wire 133 to the bottom of the coil disc 120. Alternatively, the first wire-locking part 125 can also be a wire clamp. This is only an example.
[0082] like Figures 1 to 3 As shown, in some embodiments, the cavity end face of the assembly cavity 1201, the extended ends of the first baffle 134 and the extended ends of the second baffle 124 are arranged in a staggered manner from high to low in the vertical direction. The vertical direction refers to... Figures 1 to 3 The vertical direction is as follows. The first retaining rib 134 extends downward, and the second retaining rib 124 extends upward.
[0083] It should be noted that the vertical height of the three components is limited here, emphasizing that the pot body is not placed on the supporting plate 110, the temperature measuring component 130 does not need to bear downward pressure, and part of the temperature measuring component 130 protrudes from the through hole 1101.
[0084] In other words, because the height of the extended end of the first baffle 134 is lower than the height of the cavity opening of the assembly recess 1201, it means that at least a portion of the first baffle 134 extends into the assembly recess 1201, allowing the liquid flowing along the first baffle 134 to flow more smoothly into the assembly recess 1201. Furthermore, this arrangement reduces the height from which the liquid drips from the first baffle 134 into the assembly recess 1201, thereby reducing the potential energy of the dripping liquid and minimizing splashing, further ensuring that the liquid does not wet the lead wire 133. When the first baffle 134 is fully extended into the assembly recess 1201, it further facilitates the smoother and more complete dripping of the liquid flowing along the first baffle 134 into the assembly recess 1201. Of course, it can also be partially inserted into the assembly cavity 1201 to ensure that the extended end of the first baffle 134 has sufficient space with the bottom of the assembly cavity 1201, thereby improving the problem of interference with the downward displacement of the temperature measuring component 130 due to the contact between the two.
[0085] Meanwhile, since the height of the extended end of the first baffle 134 is higher than the height of the extended end of the second baffle 124, it means that when the temperature measuring component 130 is not under force, the first baffle 134 and the second baffle 124 do not overlap in the vertical direction, thus avoiding interference with the vertical displacement of the temperature measuring component 130 as much as possible.
[0086] Understandably, if the protruding length of the first baffle 134 is too large, it is very likely that when the temperature measuring component 130 moves downward under the weight of the pot, the extended end of the first baffle 134 will abut against the bottom of the mounting cavity 1201, thus restricting the downward displacement of the temperature measuring component 130 and preventing the pot body from fitting snugly against the supporting middle plate 110. Similarly, if the protruding length of the second baffle 124 is too large, it will also cause the second baffle 124 to abut against the lower end of the temperature measuring component 130 when it moves downward, thereby affecting the downward displacement of the temperature measuring component 130. Therefore, the protruding lengths of both the first baffle 134 and the second baffle 124 should not be too long to ensure that when the temperature measuring component 130 is not under downward pressure, the extended end of the first baffle 134 is above the extended end of the second baffle 124.
[0087] Of course, when the pot body is placed under the pressure measuring component 130 of the support plate 110, the first baffle 134 and the second baffle 124 can overlap in the vertical direction, as long as it does not affect the fit between the pot body and the support plate 110.
[0088] In some specific embodiments, the protruding length of the second baffle 124 is not less than 5mm. Since the second baffle 124 protrudes upward, its protruding length is also its protruding height. For example, the protruding length of the second baffle 124 can be 5mm, 6mm, 8mm, or 10mm, etc., as long as it ensures water blocking and does not restrict displacement; this is only an example for illustration.
[0089] Please see Figures 1 to 4 In some embodiments, the leakage channel 123 includes a through-hole 1231 located at the bottom of the assembly cavity 1201 and a third baffle 1232 located at the bottom edge of the through-hole 1231, the third baffle 1232 protruding downwards. That is, the third baffle 1232 also guides the liquid flowing through the through-hole 1231, thereby reducing the risk of the liquid spreading along the bottom of the assembly cavity 1201 to other positions of the coil disc 120 under its tension, ensuring as much as possible that the liquid can only drip downwards.
[0090] In some specific embodiments, the drain hole 1231 can be circular, or it can be arc-shaped, fan-shaped, or extend circumferentially along the wiring hole 1202. Alternatively, the drain hole 1231 can be square, triangular, trapezoidal, or other shapes, as long as it can ensure that the water accumulated in the assembly cavity 1201 is drained.
[0091] like Figure 7 and Figure 8 As shown, the third baffle 1232 is arranged in a ring shape that matches the shape of the water leakage hole 1231.
[0092] Alternatively, the third baffle 1232 protrudes from the bottom wall of the assembly cavity 1201 and forms a water leakage guiding area. In this water leakage guiding area, a plurality of water leakage holes 1231 penetrating the bottom of the assembly cavity 1201 are provided. The plurality of water leakage holes 1231 and the third baffle 1232 together define the water leakage channel 123.
[0093] Another alternative is a drainage channel 123 including a drainage hole 1231 and a connecting pipe connected to the drainage hole 1231, which guides the accumulated water to the collection area, thereby draining it from the base structure 100. This is only an example.
[0094] Alternatively, the drainage channel 123 may consist only of a drainage hole 1231 extending through the bottom of the assembly cavity 1201. In this case, the bottom of the assembly cavity 1201 is inclined from top to bottom with the drainage hole 1231 as the center, so as to guide the accumulated liquid.
[0095] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6In some specific embodiments, the temperature measuring assembly 130 includes a mounting base 131 and a temperature measuring element 132 disposed on the mounting base 131. A lead wire 133 is connected to the temperature measuring element 132, and a first baffle 134 protrudes from the edge of the mounting base 131 or near the edge. The mounting base 131 has a receiving cavity into which the temperature measuring element 132 extends. The cross-section of the first baffle 134 is L-shaped. That is, the first baffle 134 includes a horizontal side extending radially along the through hole 1101 and a vertical side extending vertically. Liquid dripping onto the temperature measuring assembly 130 can spread along the mounting base 131 to the horizontal side and flow outward along the horizontal side in a direction away from the lead wire 133, and then spread downward along the vertical side and drip into the mounting cavity 1201. The horizontal side can also abut against the edge of the through hole 1101 to limit the upward displacement of the temperature measuring assembly 130.
[0096] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 9 In some embodiments, the mounting base 131 is provided with a downwardly protruding limiting rib 135, which is located inside the first stop rib 134 and can abut against the second stop rib 124. At the same time, the supporting middle plate 110 is provided with a downwardly protruding supporting rib 111 on the outer periphery of the through hole 1101, which can abut against the side of the first stop rib 134 opposite to the second stop rib 124.
[0097] In actual use, an elastic element 140 is also pressed between the mounting base 131 and the cavity wall of the mounting recess 1201. The elastic element 140 is used to apply an upward moving force to the mounting base 131 and the temperature measuring element 132. That is, the temperature measuring component 130 moves downward under the weight of the pot to ensure that the pot body is in contact with the supporting middle plate 110, at which time the elastic element 140 is compressed. After the pot body is removed, the temperature measuring component 130 moves upward under the action of the elastic element 140 to reset.
[0098] One end of the elastic member 140 is sleeved on the outside of the limiting rib 135, and the other end is sleeved on the outside of the second stop rib 124, so as to provide assembly support for the elastic member 140.
[0099] Therefore, when the temperature measuring component 130 moves downward, the limiting rib 135 can abut against the second baffle 124 to limit the downward displacement of the temperature measuring component 130; and when the temperature measuring component 130 moves upward, the first baffle 134 can abut against the support rib 111 to limit the upward displacement of the temperature measuring component 130. In this way, the reliable use of the temperature measuring component 130 can be maintained. Moreover, precisely because the limiting rib 135 is located inside the first baffle 134, it will not interfere with the water-guiding effect of the first baffle 134.
[0100] Please see Figures 1 to 5 , Figures 7 to 9 In some embodiments, the coil disk 120 includes a support disk portion 122 and an annular retaining portion 121. The support disk portion 122 is connected to the outer periphery of the annular retaining portion 121, and the annular retaining portion 121 forms an assembly cavity 1201. The support disk portion 122 is used to mount coils and other structures used for electromagnetic heating. A connecting portion 127 is provided at or near the edge of the support disk portion 122 to facilitate fastening the connecting portion 127 to the support middle plate 110 using screws. For example, multiple connecting portions 127 are provided and evenly distributed along the circumference of the support disk portion 122 to improve connection reliability.
[0101] The supporting plate 110 has a fourth baffle 112 protruding downwards around the through hole 1101. The fourth baffle 112 surrounds the outer periphery of the supporting rib 111, and the projection of the fourth baffle 112 and the annular blocking part 121 in the vertical direction overlaps. That is to say, by using the cooperation of the fourth baffle 112 and the annular blocking part 121, the opening of the assembly cavity 1201 is blocked, preventing liquid from flowing out of the opening of the assembly cavity 1201, and minimizing the spread of liquid to the coil, thereby further improving the water-blocking effect.
[0102] For example, the portion of the fourth baffle 112 near its extended end can extend into the assembly cavity 1201. The fourth baffle 112 has a limiting step, and the limiting step can abut against the top end face of the annular retaining portion 121. Alternatively, the fourth baffle 112 can surround the outer periphery of the annular retaining portion 121 and abut against the annular retaining portion 121 through the limiting step. Or, when the coil 120 is fixed to the support plate 110 via the support plate portion 122, the top end face of the annular retaining portion 121 abuts against the lower surface of the support plate 110. It is sufficient that it forms a retaining wall at the opening of the assembly cavity 1201 to prevent liquid leakage; this is merely an example.
[0103] Please see Figure 1 , Figure 2 , Figure 10 and Figure 11In some embodiments, the base structure 100 further includes a base body 150, which supports and is connected to a support plate 110. The base body 150 and the support plate 110 together form an assembly cavity 1001, in which the coil disc 120 is disposed. The bottom of the base body 150 has a water outlet 1501 corresponding to the position of the drainage hole 1231, and a fifth baffle 153 protrudes from the side of the base body 150 near the functional device at the water outlet 1501. It is understood that liquid drained through the aforementioned drainage channel 123 can drip to the water outlet 1501 and be discharged from the water outlet 1501 outside the base structure 100; and, with the fifth baffle 153, liquid dripping to the water outlet 1501 can be prevented from flowing towards the functional device and causing malfunction, reducing safety hazards. In other words, by using the fifth baffle 153, a drainage area can be formed on the body 150 surrounding the water outlet 1501. This not only temporarily stores the liquid dripping through the water leakage channel 123, but also prevents the liquid from spreading to other locations.
[0104] The functional components include the aforementioned power board, and may also include components such as cooling fans, other than the temperature measuring component 130, that are mounted on the base body 150.
[0105] Furthermore, the seat body 150 includes a bottom sealing plate 151 and a surrounding plate 152, which are snapped together and fixed. The supporting middle plate 110 is snapped together and fixed to the surrounding plate 152, and is fastened to the bottom sealing plate 151 with screws, thereby improving assembly reliability.
[0106] Please see Figure 1 , Figure 2 and Figure 11 Another embodiment of this application provides a cooking appliance, including a pot body and the aforementioned base structure 100. The pot body is supported by a supporting middle plate 110 of the base structure 100. A temperature measuring component 130 can contact the bottom of the pot body for temperature measurement. Liquid remaining on the pot body flows to the temperature measuring component 130, seeps in through the assembly gap 1002, and spreads downwards along the temperature measuring component 130. It drips through the first baffle 134 to the annular water storage area 1200, and then drips along the drainage channel 123 to the water outlet 1501 and is discharged. This significantly reduces the risk of the lead wire 133 becoming wet and other parts of the coil 120 becoming wet due to excessive water accumulation in the annular water storage area 1200, thus significantly improving waterproof reliability.
[0107] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0108] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
