[Technical Field]
[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority based on a Chinese patent application filed with the China Patent Office on November 17, 2021, with application number 202122828988.9, for the invention title "Cooking appliance", and a Chinese patent application filed with the China Patent Office on December 1, 2021, with application number 202123039938.9, for the invention title "Cooking appliance".
[0002] The present application relates to the technical field of kitchen appliances, and in particular to cooking appliances. [Background technology]
[0003] In conventional cooking appliances, such as stir-fries, a pan is typically installed so that it can rotate during cooking to improve the cooking quality of ingredients, and a temperature sensor is installed in the rotating pan to measure temperature. Generally, the temperature sensor rotates with the pan. However, in reality, during cooking, ingredients are always located in a low position in the pan due to the effect of gravity, and the ingredients do not rotate with the pan. Therefore, if the temperature sensor rotates with the pan, the temperature of the part of the pan that actually heats the ingredients cannot be reflected in real time, resulting in inaccurate temperature measurement. Alternatively, a conventional solution has been to install a temperature sensor fixed to a frame rather than rotating with the pan, but the position at which the temperature sensor measures the temperature of the pan does not correspond to the position of the part of the pan that heats the ingredients, resulting in the same problem of inaccurate temperature measurement. Summary of the Invention [Problem to be solved by the invention]
[0004] Therefore, the present application provides a cooking appliance that can reduce the temperature difference between the detection result and the food material, and is advantageous in improving the accuracy and stability of temperature measurement and improving cooking quality.

[0021] In order to make the above-mentioned objects, features and advantages of the present application more clearly understood, the present application will be described in more detail below with reference to the drawings and specific embodiments. It should be noted that, unless mutually inconsistent, the examples and features in the examples in the present application can be combined with each other.
[0022] In the following description, many specific details are set forth to provide a thorough understanding of the present application; however, the present application may be implemented in other ways than those described herein, and the scope of protection of the present application is not limited to the specific embodiments disclosed below.
[0023] Hereinafter, a cooking appliance 100 according to several embodiments of the present application will be described with reference to Figures 1 to 13. The cooking appliance 100 may be a smart cooking appliance or other appliances that can meet your requirements.
[0024] Conventional cooking appliances, such as stir-fries, typically have a temperature sensor attached to the pan to detect the temperature of the pan, and then estimate the temperature of the ingredients in the pan to achieve temperature control, thereby improving the cooking quality of the ingredients. Typically, the temperature sensor is attached to the pan and rotates as the pan rotates.
[0025] However, when the cooking appliance is in the cooking position, the pot rotates, but most of the food inside the pot falls due to gravity and remains at the bottom of the pot in the cooking position for a long time. That is, at this time, there is no food or only a small amount of food at the top of the pot in the cooking position. If the pot rotates until the part where the temperature sensor is attached is at the top of the pot in the cooking position, the distance between the temperature sensor and the food becomes large, making it impossible to accurately represent the temperature of the food or the temperature of the part of the pot body that actually heats the food. Furthermore, this may affect the overall temperature control accuracy of the cooking appliance and affect the cooking quality of the food.
[0026] 1 and 2 , a cooking appliance 100 according to an embodiment of the present disclosure includes a base, a pot 120, and at least one temperature measurement assembly 130. The pot 120 is rotatably mounted within the base. For example, when the cooking appliance 100 is in a cooking position, the pot 120 can rotate relative to the base to ensure uniform heating of ingredients. The at least one temperature measurement assembly 130 is mounted on the base, and includes a first temperature measurement assembly 137. The first temperature measurement assembly 137 is mounted opposite the pot 120 to measure the temperature of ingredients in the pot 120. In other words, in the cooking appliance 100 according to an embodiment of the present disclosure, the temperature measurement assembly 130 is mounted on the base rather than the pot 120. This keeps the position of the temperature measurement assembly 130 fixed while the pot 120 rotates relative to the base, which is advantageous for improving the stability of temperature measurement by the temperature measurement assembly 130 and extending the service life of the temperature measurement assembly 130.
[0027] Furthermore, first temperature measurement assembly 137 is disposed opposite the food area of pot 120, and the area where the food in pot 120 comes into contact with pot 120 when cooking appliance 100 is in the cooking position is referred to as the food area. For example, during cooking, most of the food in pot 120 falls due to gravity and remains at the bottom of pot 120 in the cooking position for a long time. At this time, the food area of pot 120 can be understood as the area near the bottom of pot 120 in the cooking position, where the food comes into contact with pot 120.
[0028] In other words, the food area of pot 120 is not a fixed area relative to pot 120 itself as it rotates, but refers primarily to the area where the food comes into contact with pot 120, i.e., the area at the bottom of pot 120 in the rotated position. Therefore, by locating first temperature measurement assembly 137 opposite the food area of pot 120, the distance between first temperature measurement assembly 137 and the food in pot 120 is shortened, and the temperature difference between the temperature detected by first temperature measurement assembly 137 and the food is reduced, which is advantageous for improving the accuracy of food temperature detection by first temperature measurement assembly 137 and improving the cooking quality of the food.
[0029] Specifically, the number of temperature measurement assemblies 130 can be one, two, three, or more, and different quantities of temperature measurement assemblies 130 can meet different temperature measurement accuracy requirements and expand the range of product use. Note that, to further improve the temperature measurement accuracy of the temperature measurement assemblies 130, the number of first temperature measurement assemblies 137 can be one, two, or more.
[0030] In the above embodiment, as shown in FIGS. 1 and 2 , the base includes a case 110 and a heating assembly 140 mounted within the case 110. The pan 120 is also mounted within the case 110 and is rotatable relative to the case 110. The case 110 serves as a support case for the pan 120 and the heating assembly 140, primarily functioning to hold the pan 120 and the heating assembly 140. The heating assembly 140 is positioned between the case 110 and the pan 120 and serves to heat the pan 120. The temperature measuring assembly 130 may be mounted on the base or the heating assembly 140. For example, the temperature measuring assembly 130 may be mounted on a bracket for the heating assembly 140, or another component may be mounted within the case 110, and the temperature measuring assembly 130 may be mounted on the other component, thereby achieving the above-described function.
[0031] Furthermore, heating assembly 140 includes at least one coil disk 141, which may have an annular and / or arc-shaped structure. As shown in FIGS. 2 and 4, the annular coil disk 141 is disposed around the outer periphery of pot 120. For example, the annular coil disk 141 may be three-dimensional, and the three-dimensional coil disk may be disposed around the outer periphery of pot 120 as a single unit. As shown in FIGS. 1 and 6, the arc-shaped coil disks 141 may be distributed around part of the outer periphery of pot 120, or multiple arc-shaped coil disks 141 may be disposed together around the outer periphery of pot 120. The number of coil disks 141 can be varied to meet the needs of different coil disk 141 structures, installation positions, and heating efficiencies, thereby expanding the scope of use of the product.
[0032] The coil disks 141 of the heating assembly 140 may have one of an annular structure and an arc-shaped structure, or the coil disks 141 of the heating assembly 140 may have both an annular structure and an arc-shaped structure. In either of the above cases, the number of coil disks 141 having an annular structure may be one or at least two, and the number of coil disks 141 having an arc-shaped structure may be one or at least two.
[0033] 1, 6, 8, and 9, the temperature measurement assembly 130 is disposed opposite the center of the heating assembly 140. For example, the temperature measurement assembly 130 is an infrared temperature measurement assembly, and a light-transmitting area 142 is disposed at the center of the heating assembly 140. In this manner, the infrared temperature measurement assembly can receive infrared rays emitted from the pot 120 through the light-transmitting area 142 at the center of the heating assembly 140 to measure the temperature of the food area in the pot 120, which is advantageous in improving the accuracy and reliability of detection.
[0034] Specifically, the light-transmitting area 142 may be an openwork structure or a light-transmitting member, for example, the light-transmitting member may be a light-transmitting plate so that the detection light of the temperature measurement assembly 130 can pass through the light-transmitting area 142 at the central position of the heating assembly 140 to detect the temperature of the pot 120.
[0035] Additionally, heating assembly 140 is typically used to heat pan 120 when pan 120 is in the cooking position. , Canada Since the central position of the heating assembly 140 is usually opposite the food area of the pot 120, by arranging the temperature measurement assembly 130 opposite the center of the heating assembly 140, the temperature measurement assembly 130 can quickly, accurately, and reliably measure the food temperature, which is advantageous for improving the cooking quality of the food.
[0036] In some possible embodiments of the present application, as shown in Figures 3, 4 and 5, the temperature measurement assembly 130 is positioned opposite the high temperature area 123 of the pot 120, and when the cooking appliance is in a cooking position, the area facing the heating assembly 140 as the pot 120 rotates relative to the case 110 is the high temperature area 123.
[0037] Typically, pot 120 includes high temperature area 123, high temperature zone 125, and low temperature zone 124. When cooking appliance 100 is in the cooking position, high temperature area 123 faces heating assembly 140 as pot 120 rotates relative to case 110. This area has the highest heating temperature and is the area that receives concentrated heating. High temperature zone 125 is adjacent to high temperature area 123, has a relatively high heating temperature, and is the area that receives supplementary heating. Low temperature zone 124 is the portion of high temperature zone 125 located away from high temperature area 123, and is usually at a relatively low temperature and does not heat ingredients.
[0038] Due to differences in the structure and installation position of heating assembly 140, there may be one high temperature zone 125 located between high temperature region 123 and low temperature zone 124, or there may be two high temperature zones 125 distributed on both sides of high temperature region 123, with one high temperature zone 125 located between high temperature region 123 and low temperature zone 124, as shown in Figures 3 and 5. Here, when cooking appliance 100 is in the cooking position, there is usually a high probability that the food material region and high temperature zone 123 will overlap.
[0039] In other words, high temperature area 123 of pot 120 is not a fixed area relative to pot 120 itself during the rotation of pot 120, but mainly refers to the area where pot 120 faces heating assembly 140. Because heating assembly 140 is used to heat pot 120, when pot 120 is in the cooking position, food ingredients usually come into contact with high temperature area 123 of pot 120 to ensure good cooking efficiency. That is, when cooking appliance 100 is in the cooking position, there is usually a high probability that the food area and high temperature area 123 overlap.
[0040] That is, depending on the installation position of heating assembly 140, the food area of pot 120 can be positioned within high temperature region 123 of pot 120 when pot 120 is in the cooking position. Therefore, by installing temperature measurement assembly 130 opposite high temperature region 123 of pot 120, temperature measurement assembly 130 can quickly, accurately, and reliably measure the food temperature accurately.
[0041] Furthermore, the number of temperature measuring assemblies 130 is at least one, and if the number of temperature measuring assemblies 130 is one, the temperature measuring assembly 130 may be arranged opposite the center of the heating assembly 140, or the temperature measuring assembly 130 may be arranged opposite the high temperature region 123 of the pot 120.
[0042] When there are at least two temperature measuring assemblies 130, all of the temperature measuring assemblies 130 may be positioned facing the center of the heating assembly 140, or all of the temperature measuring assemblies 130 may be positioned facing the high temperature area 123 of the pan 120, or some of the temperature measuring assemblies 130 may be positioned facing the center of the heating assembly 140 and others may be positioned facing the high temperature area 123 of the pan 120. By positioning the temperature measuring assemblies 130 in different positions, various mounting methods for the temperature measuring assemblies 130 can be realized, broadening the range of applications while ensuring the accuracy of temperature measurement.
[0043] 6 and 7, in some possible embodiments of the present application, the temperature measurement assembly 130 further includes a second temperature measurement assembly that is located on at least one side of the first temperature measurement assembly 137 and assists the first temperature measurement assembly 137. The first temperature measurement assembly 137 and the second temperature measurement assembly jointly realize temperature measurement, which is advantageous to improving the accuracy and reliability of temperature measurement. Here, when the cooking appliance 100 is in the cooking position, the pot 120 can rotate back and forth relative to the base along the direction indicated by arrow G in FIG. 7.
[0044] Furthermore, the present application does not limit the number and distribution manner of the second temperature measurement assemblies, and one or more second temperature measurement assemblies may be distributed on the same side of the first temperature measurement assembly 137, or one or more second temperature measurement assemblies may be distributed on both sides of the first temperature measurement assembly 137.
[0045] As shown in Figure 6, the number of second temperature measurement assemblies may be one and include second temperature measurement assembly a138, and second temperature measurement assembly a138 and first temperature measurement assembly 137 may be distributed opposite each other on both sides of pot 120. As shown in Figure 7, the number of second temperature measurement assemblies may be two and include second temperature measurement assembly a138 and second temperature measurement assembly b139, and second temperature measurement assembly a138 and second temperature measurement assembly b139 may be provided on both sides of first temperature measurement assembly 137, respectively.
[0046] As shown in Figures 6, 8 and 9, the area of pot 120 that is radiated by temperature measuring assembly 130 when cooking appliance 100 is in the cooking position is called detection area 122, and an infrared emitting coating layer 121 is provided on the outer wall of pot 120. By providing infrared emitting coating layer 121, the infrared emitting rate of pot 120 can be increased during the heating process, which is advantageous in improving the detection reliability of temperature measuring assembly 130.
[0047] By ensuring that infrared emitting coating layer 121 covers at least detection area 122 of pot 120, it is possible to ensure that infrared emitting coating layer 121 is included within the measurement area of temperature measuring assembly 130 regardless of the rotation angle of pot 120, further improving the reliability and accuracy of detection by temperature measuring assembly 130. Preferably, infrared emitting coating layer 121 on the outer wall of pot 120 is a high-hardness, high-temperature-resistant infrared emitting coating layer 121 that can ensure an infrared radiation rate of 95% or more in the wavelength range of 6 μm to 16 μm. Preferably, infrared emitting coating layer 121 is a graphene ceramic composite coating layer, but it goes without saying that infrared emitting coating layer 121 may be a coating layer made of other materials that meet the requirements.
[0048] 8 and 9, infrared emitting coating layer 121 may be provided over the entire detection area 122 of pot 120. For example, when pot 120 is in a cooking position, infrared emitting coating layer 121 may be provided over the entire area that faces temperature measuring assembly 130 as pot 120 rotates once. Alternatively, as shown in FIG. 6, in order to further increase the infrared emissivity, in addition to providing infrared emitting coating layer 121 in detection area 122, infrared emitting coating layer 121 may also be provided at other positions on pot 120. For example, infrared emitting coating layer 121 may be provided around the outer periphery of pot 120 in a portion of detection area 122 of pot 120 that is close to the bottom of the pot.
[0049] 1, 8, 9, and 10, in some possible embodiments of the present application, the case 110 is provided with a detection port 111, and the temperature measuring assembly 130 is drilled through the detection port 111 and removably connected to the case 110. This arrangement makes it easy to attach and detach the temperature measuring assembly 130 to and from the case 110, and allows the temperature measuring assembly 130 to be removed from the case 110 for replacement, maintenance, and cleaning, which is advantageous for improving the experience of replacing, maintaining, and cleaning the temperature measuring assembly 130, and facilitates improving maintenance efficiency and extending the service life of the temperature measuring assembly.
[0050] Temperature measuring assembly 130 may include detection window 131. Dust or dirt on detection window 131 will affect the accuracy of temperature measurement by temperature measuring assembly 130. Therefore, removing temperature measuring assembly 130 from case 110, cleaning detection window 131 of temperature measuring assembly 130, and then attaching the cleaned temperature measuring assembly 130 to case 110 to detect the temperature of pot 120 will be advantageous in improving the accuracy of temperature measurement by temperature measuring assembly 130.
[0051] Furthermore, by drilling the temperature measuring assembly 130 into the detection port 111 and removably connecting it to the case 110, there is no need to open the case 110, and the temperature measuring assembly 130 can be attached and detached to and from the case 110 from the outside of the case 110, which further simplifies the operation of attaching and detaching the temperature measuring assembly 130, making the operation more convenient and suitable for widespread use.
[0052] 10 and 11 , in the above embodiment, the temperature measuring assembly 130 further includes an infrared temperature measuring sensor 133 and a mounting seat 134, the infrared temperature measuring sensor 133 is detachably connected to the mounting seat 134, the mounting seat 134 is connected to the case 110, and the infrared temperature measuring sensor 133 is connected to the mounting seat 134. That is, the infrared temperature measuring sensor 133 can be detachably attached to the case 110 by the mounting seat 134, which makes the structure simple and the operation convenient.
[0053] Here, by removably connecting the infrared temperature measuring sensor 133 to the mounting seat 134, the mounting seat 134 to which the infrared temperature measuring sensor 133 is attached can be removed from the case 110, and then the infrared temperature measuring sensor 133 can be removed from the mounting seat 134 for maintenance, replacement, or cleaning, which makes operation convenient.
[0054] Here, infrared temperature measuring sensor 133 is communicatively connected to the control system of cooking appliance 100, and provides real-time feedback of the measured temperature of the food area at the bottom of pot 120. Specifically, the fixed position of infrared temperature measuring sensor 133 satisfies the requirement that it can measure the temperature of the lowest point at the bottom of the food area of pot 120 when pot 120 is in the cooking position.
[0055] In the above embodiment, as shown in Figures 8, 9, 10 and 11, the temperature measuring assembly 130 further includes a magnetic shield ring 132 inserted into the detection port 11 and connected to the case 110, and the mounting seat 134 is detachably connected to the magnetic shield ring 132 located outside the case 110. The detachable connection between the mounting seat 134 and the magnetic shield ring 132 enables the infrared temperature measuring sensor 133 to be detachably connected to the case 110, which simplifies the structure and facilitates operation.
[0056] Here, the infrared temperature measuring sensor 133 includes a detection window 131, which is located inside a magnetic shield ring 132, which reduces the possibility that the detection window 131 of the infrared temperature measuring sensor 133 will be contaminated and affect its detection accuracy. The installation of the magnetic shield ring 132 reduces interference with the infrared temperature measuring sensor 133 caused by the electromagnetic field generated by the heating assembly 140, and further improves the accuracy and reliability of temperature measurement by the infrared temperature measuring sensor 133.
[0057] Specifically, the detachable connection of the infrared temperature measuring sensor 133, magnetic shield ring 132, mounting seat 134, etc. is not limited to a specific connection method, including, but not limited to, screw connection, magnetic adsorption, pin / snap fit connection, etc. For example, when it is necessary to remove the infrared temperature measuring sensor 133 from the case 110, the mounting seat 134 is pulled out from the magnetic shield ring 132 to separate it from the case 110, and the infrared temperature measuring sensor 133 attached to the mounting seat 134 is separated from the case 110 together with the mounting seat 134, thereby facilitating maintenance and cleaning of the infrared temperature measuring sensor 133 and making operation more convenient. Here, the direction indicated by arrow K in Figures 8 and 9 is the direction in which the infrared temperature measuring sensor 133 is removed and attached.
[0058] Furthermore, as shown in FIG. 7, by rotating the pot 120 to an appropriate position relative to the base, the detection port 111 of the pot 120 can be positioned horizontally, making it easier to attach and remove the temperature measurement assembly 130.
[0059] 10 and 13, magnetic shield ring 132 includes first end face 135 and second end face 136, which are opposed to each other. First end face 135 is connected to case 110, and second end face 136 is located outside case 110 and is detachably connected to infrared temperature measuring sensor 133. The end face of detection window 131 closest to pot 120 is upper end face 1331. If the distance between upper end face 1331 and first end face 135 is D1, the setting range for D1 is 4 mm to 12 mm. The end face of detection window 131 away from pot 120 is lower end face 1332. If the distance between lower end face 1332 and second end face 136 is D2, the setting range for D2 is 4 mm to 12 mm.
[0060] This arrangement ensures that the electromagnetic field generated by the coil disc does not interfere with the infrared temperature measuring sensor 133, thereby ensuring the accuracy and reliability of temperature measurement by the infrared temperature measuring sensor 133. It is preferable that the values of D1 and D2 are 8 mm, respectively, but it goes without saying that D1 and D2 may be other values that meet the requirements.
[0061] As shown in FIGS. 12 and 13 , the intersection of the radiation range of the temperature measurement assembly 130 and the plane on which the first end face 135 is located is a first region, which is located inside the opening of the first end face 135 of the magnetic shield ring 132. For example, let β be the included angle of the infrared radiation emitted by the infrared temperature measurement sensor 133 through the detection window 131 in the vertical central plane of the infrared temperature measurement sensor 133, let P be the distance between the intersection points of the two sides of the included angle β and the first end face 135 of the magnetic shield ring 132, and let Q be the diameter of the opening of the first end face 135 of the magnetic shield ring 132. Then, P≦Q, which indicates that the first region is located inside the opening of the first end face 135. In this way, the magnetic shield ring 132 does not block the radiation range through the detection window 131, which further ensures the reliability and accuracy of the temperature measurement by the temperature measurement assembly 132.
[0062] 14, heating assembly 140 is provided on the outside of pot 120, with at least one portion of heating assembly 140 located on either side of the axis of pot 120, and heating assembly 140 has different elevations along the circumferential direction of pot 120 and in the axial direction of pot 120. Here, the cooking appliance may further include a base, and pot 120 may be rotatably provided on the base about a rotation axis to achieve rotational heating.
[0063] In the cooking appliance according to the embodiment of the present application, at least one part and at least another part of the heating assembly 140 are located on either side of the axis of the pot 120, respectively, and the heating assembly 140 has different heights in the axial direction of the pot 120 along the circumferential direction of the pot 120. Therefore, when the pot 120 rotates to heat, the heating area formed on the pot 120 is not only formed in the area corresponding to the heating assembly 140, but also in the areas corresponding to the upper and lower sides of the heating assembly 140, thereby increasing the coverage height of the heating area in the axial direction of the pot 120 and dispersing the heating area, thereby improving the uniformity of heat reception of the pot 120 and improving the cooking effect of the food.
[0064] Furthermore, since no heat concentration phenomenon occurs in the pot 120, localized high temperatures are not generated, and the peeling off of the non-stick coating on the surface of the pot 120 and deformation of the pot 120 due to localized thermal stress can be avoided, thereby extending the service life of the pot 120 and providing conditions for accurate measurement and control of the temperature of the pot.
[0065] In the present embodiment, as shown in FIG. 14, heating assembly 140 is annular and fits onto the exterior of pot 120, and the contour of heating assembly 140 fits the contour of pot 120.
[0066] In the above embodiment, by surrounding pot 120 with heating assembly 140 in a ring-shaped structure, during the process of pot 120 rotating and heating, the area of pot 120 that has just rotated away from heating assembly 140 continues to be heated in correspondence with heating assembly 140 after rotating 180 degrees, thereby preventing the temperature of that part of pot 120 from dropping rapidly due to a long time of heat exchange with the air, and ensuring that the heated area of pot 120 can always be maintained at a constant temperature. Furthermore, the uniformity of heat received by pot 120 is further improved, further improving the cooking effect of the food.
[0067] In the above embodiment, by fitting the contour shape of the heating assembly 140 to the contour shape of the pan 120, it is possible to ensure that the distance between each position on the heating assembly 140 and the pan 120 is similar, thereby better ensuring that the pan 120 receives heat uniformly.
[0068] In the present embodiment, as shown in FIG. 14, the heating assembly 140 is tilted relative to the axis of the pan 120, and one end of the heating assembly 140 away from the opening of the pan 120 extends to the bottom region or bottom edge of the pan 120.
[0069] In the above embodiment, heating assembly 140 is tilted relative to the axis of pot 120, and therefore has different heights along the axial direction of pot 120 along the circumferential direction of pot 120. Furthermore, by extending one end of heating assembly 140 away from the opening of pot 120 to the bottom region or bottom edge of pot 120, when pot 120 is rotated for heating, the heating area formed in pot 120 by heating assembly 140 can cover from the open end of pot 120 to the bottom region or bottom edge of pot 120, thereby increasing the area of the heating area in pot 120, enhancing the wok hei (heating gas) in pot 120, and further improving the cooking effect of food.
[0070] 14, in the present embodiment, the axis of heating assembly 140 and the axis of pot 120 form an included angle α, which may be 10 to 45°. As a result, when pot 120 is rotated and heated, the heating area formed in pot 120 by heating assembly 140 can cover more than two-thirds of the area of pot 120, thereby ensuring sufficient wok hei in pot 120 and further improving the cooking effect.
[0071] 15, when pot 120 is stationary, heating assembly 140 forms an inclined, annular high-temperature region 123 on pot 120. When pot 120 rotates to heat, heating assembly 140 forms a high-temperature zone 125 on the surface of pot 120. This high-temperature zone 125 can cover more than two-thirds of the surface of pot 120, and theoretically could cover the entire surface of pot 120. Furthermore, the temperature in high-temperature region 123 is uniform around the circumference of pot 120. As pot 120 rotates to heat, the temperature is also uniform in the axial direction of pot 120. This allows for uniform heating in both the circumferential and axial directions of pot 120, ensuring sufficient airflow within pot 120 and further improving the cooking effect.
[0072] In an embodiment of the present application, as shown in FIG. 14, the heating assembly 140 includes a coil disk 141, which has a plurality of first heat dissipation holes 21 arranged at intervals along its circumferential direction, and the extension direction of the first heat dissipation holes 21 is perpendicular to the winding direction of the coil disk 141.
[0073] In the above embodiment, the first heat dissipation holes 21 are used to dissipate heat from the coil disk 141 to ensure normal operation of the coil disk 141. Specifically, the multiple first heat dissipation holes 21 are uniformly arranged along the circumferential direction of the coil disk 141, thereby improving the uniformity of heat dissipation from the coil disk 141 by the first heat dissipation holes 21. Furthermore, the extension direction of the first heat dissipation holes 21 is perpendicular to the winding direction of the coil disk 141, thereby ensuring the strength of the entire coil disk 141.
[0074] In the embodiment of the present application, the number of winding layers of the coil disk 141 may be at least 2. This can ensure that the coil disk 141, which has a limited area, has a sufficient number of coil windings, so that the coil disk 141 can match the inductance amount and achieve the heating power required for the coil disk 141.
[0075] The winding depth of coil disk 141 can be determined based on the shape and dimensions of pot 120 and the planned heating area. For example, if the dimensions of pot 120 are large and the planned heating area is large, the winding depth of coil disk 141 may be increased, or conversely, the winding depth of coil disk 141 may be decreased.
[0076] In the embodiment of the present application, as shown in FIG. 14, the cooking appliance 100 further includes a first bracket 3 provided on the outside of the heating assembly 140 and having at least one magnetic body 31 provided thereon.
[0077] In the above embodiment, the magnetic material 31 is provided on the first bracket 3, and the first bracket 3 is provided on the outside of the heating assembly 140. This reduces the magnetic flux lines scattered in the air, reduces the leakage magnetic flux of the coil, and distributes the magnetic flux lines to one side of the pot 120 as much as possible to ensure that the coil disk 141 reaches the required heating power.
[0078] Here, there are multiple structural forms of the first bracket 3, as long as it can be fixed to the outside of the heating assembly 140 and the magnetic body 31 can be attached. In the embodiment of the present application, as shown in Fig. 14, the first bracket 3 is annular and is provided coaxially with the heating assembly 140, and the contour shape of the first bracket 3 fits the contour shape of the heating assembly 140. When there are multiple magnetic bodies 31, the multiple magnetic bodies 31 are arranged at intervals along the circumferential direction of the first bracket 3.
[0079] In the above embodiment, the annular first bracket 3 has a contour shape that fits the contour shape of the heating assembly 140 and is arranged coaxially with the heating assembly 140. This allows the distance between each magnetic body 31 and the coil disk 141 to be shortened, which is advantageous for reducing leakage magnetic flux. Alternatively, multiple magnetic bodies 31 may be uniformly arranged along the circumferential direction of the first bracket 3, and the distance between two adjacent magnetic bodies 31 may be shortened. This is advantageous for reducing leakage magnetic flux.
[0080] In the above embodiment, the first bracket 3 may be formed by connecting a plurality of annular spacer strips arranged at intervals, and a plurality of magnetic bodies 31 may be uniformly fixed to the spacer strips, thereby ensuring the strength of the entire first bracket 3. The first bracket 3 may also be fixed to the coil disc 141 by connecting members such as slots and / or screws.
[0081] In an embodiment of the present application, referring to FIG. 14, the cooking appliance 100 further includes a second bracket 4 arranged on the outside of the pot 120, the heating assembly 140 is arranged on the second bracket 4, the second bracket 4 is provided with a second heat dissipation hole 41, and a gap is provided between the second bracket 4 and the pot 120.
[0082] In the above embodiment, by providing second bracket 4 and mounting heating assembly 140 on second bracket 4, heating assembly 140 can be stably attached to the outside of pot 120, which is advantageous for heating pot 120 using heating assembly 140. Furthermore, by providing second heat dissipation holes 41 on second bracket 4, heat from heating assembly 140 and pot 120 can be easily dissipated through second heat dissipation holes 41.
[0083] In the above embodiment, second bracket 4 is made of a non-magnetically conductive material so as not to shield the magnetic field, ensuring that heating assembly 140, i.e., coil disc 141, heats only pot 120, thereby ensuring the heating effect of pot 120. Specifically, second bracket 4 may be made of engineering plastic or nylon and glass fiber material.
[0084] In the above embodiment, a gap is provided between second bracket 4 and pot 120, allowing for a certain distance between coil disk 141 and pot 120. This distance affects the carrier inductance of coil disk 141 and the heat dissipation characteristics of the outer surface of pot 120. For example, a smaller distance reduces the carrier inductance of coil disk 141, reducing the heating power of coil disk 141 and adversely affecting heat dissipation characteristics of the outer surface of pot 120. Generally, a distance greater than 15 mm ensures sufficient carrier inductance for coil disk 141 and favors heat dissipation characteristics of the outer surface of pot 120.
[0085] Here, second bracket 4 may have a variety of structural forms, as long as it can attach heating assembly 140 and be fixed to the outside of pot 120 without rotating with pot 120. In the embodiment of the present application, as shown in FIG. 1, second bracket 4 has a tubular structure with both ends open, and second bracket 4 is fitted onto the outside of pot 120, with the contour shape of second bracket 4 fitting the contour shape of pot 120.
[0086] According to the above embodiment, the contour shape of the heating assembly 140 fits the contour shape of the pot 120, so by installing the second bracket 4 so that the contour shape fits the contour shape of the pot 120, it becomes easy to attach the heating assembly 140 to the second bracket 4 and also ensures stable attachment of the heating assembly 140 to the second bracket 4.
