Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly relates to an induction cooker and a control method thereof. Background Art

[0002] During the use of an induction cooker, the situation often occurs that the placement position of the cookware is deviated from the position of the heating coil, resulting in uneven heating of the cookware.

[0003] In the related art, patterns are usually silk-screened on the cover plate, and the position of the pattern corresponds to the position of the high-temperature area on the cover plate. The pattern is used to remind the user of the position of the high-temperature area on the cover plate, so as to facilitate the user to place the cookware in the high-temperature area, thereby facilitating the user to use the induction cooker.

[0004] However, with the long-term use of the induction cooker, the patterns on the cover plate will be worn and gradually blurred, affecting the user's observation of the position of the high-temperature area. Summary of the Invention

[0005] An embodiment of the present invention provides an induction cooker and a control method thereof, which are used to solve the problem that the display of the high-temperature area on the induction cooker is not obvious.

[0006] To achieve the above object, in the first aspect of the present application, an induction cooker is provided. The induction cooker includes a cooker body, a cover plate, a light guide ring, a light strip, and a controller. The cooker body has a heating part. The cover plate is connected to the heating side of the cooker body, and a heatable area that can transmit light is formed on the cover plate. The light guide ring is disposed on the side of the heatable area close to the heating part and is connected to the cooker body. The orthographic projection of the light guide ring on the cover plate is located within the heatable area. The orthographic projection of the heating part on the cover plate is located within the orthographic projection of the light guide ring on the cover plate. The light strip extends around the light guide ring along the circumferential direction of the light guide ring and is attached to the light guide ring.

[0007] The controller is connected to the light strip and is configured to: determine whether the induction cooker is turned on; if the induction cooker is turned on, control the light strip to emit light, so that the light emitted by the light strip passes through the light guide ring and forms an aperture in the heatable area.

[0008] After the user starts the induction cooker, the controller receives the start information of the induction cooker, and then controls the light strip to be powered on, so that the light strip emits light. Since the light strip is disposed on the side of the heatable area close to the heating part, the light emitted by the light strip can pass through the light guide ring and project an aperture in the heatable area on the cover plate. Since the cover plate is disposed on the heating side of the cooker body, the orthographic projection of the heating part on the cover plate is located within the aperture. In this way, the high-temperature area generated on the cover plate when the heating part works can be located within the aperture, so as to remind the user of the position of the high-temperature area on the cover plate through the aperture, and further remind the user of the position (i.e., the high-temperature area) for placing the cookware.

[0009] In some embodiments of the present application, the controller is further configured to: determine whether the cookware is located within the heating area; if the cookware is located within the heating area, control the light-emitting member to continue emitting light for a preset duration and then turn off.

[0010] In this way, after the cookware is determined to be placed within the light circle, the controller will control the light strip to turn off after a preset duration, thereby avoiding the light strip being in a continuously lit state during the use of the induction cooker, reducing the lighting duration of the light strip, reducing the power consumption of the light strip during the operation of the induction cooker, and further reducing the power consumption of the induction cooker to reduce the usage cost of the induction cooker.

[0011] In some embodiments of the present application, the induction cooker further includes a temperature sensor. The temperature sensor is disposed on one side of the heating area close to the heating part and is in contact with the heating area for detecting the actual temperature of the heating area. The controller is connected to the temperature sensor, and the controller is further configured to: if the induction cooker is not turned on, obtain the actual temperature and determine whether the actual temperature is greater than or equal to a preset temperature; if the actual temperature is greater than or equal to the preset temperature, control the light strip to emit light; if the actual temperature is less than the preset temperature, control the light strip to turn off.

[0012] In this way, after the user uses the induction cooker, the user can determine whether the actual temperature of the heating area is greater than the preset temperature by observing whether the light strip emits light, that is, whether there is a light circle displayed on the cover plate, so as to judge the temperature of the heating area. When the light circle has brightness, it can remind the user that the temperature of the heating area is relatively high, reducing the possibility of the user being scalded and improving the user experience of using the induction cooker.

[0013] In some embodiments of the present application, the controller is further configured to: determine whether the light strip is turned off; if the light strip is turned off, determine again whether the cookware is located within the heating area; if the cookware deviates from the heating area, control the light strip to emit light.

[0014] In this way, during the operation of the induction cooker, if the cookware deviates from the heating area, the controller will control the light strip to emit light, reminding the user that the cookware has deviated from the heating area, so that the user can put the cookware back into the heating area according to the reminder of the light strip, ensuring the heating effect of the induction cooker on the cookware.

[0015] In some embodiments of the present application, the controller is further configured to: obtain the output power of the induction cooker; adjust the change state of the light strip according to the change of the output power, where the change state of the light strip is at least one of color change and brightness change.

[0016] In this way, the user can judge the magnitude of the output power of the induction cooker according to the different change states of the light strip, which is convenient for the user to judge the magnitude of the output power of the induction cooker, facilitating the user to adjust the output power of the induction cooker, and further improving the user experience of using the induction cooker.

[0017] In some embodiments of the present application, the furnace body includes a plurality of brackets and fixing members. The plurality of brackets are arranged at intervals along the circumferential direction of the heat conduction channel on the heating part. The fixing member is arranged on the plurality of brackets. An avoidance channel and a first recess are formed on the fixing member. The orthographic projection of the heating part in the heating area is located within the orthographic projection of the avoidance channel in the heating area. The first recess is located on the side of the fixing member close to the heating area, and the light guide ring and the light strip are embedded in the first recess.

[0018] Through the above arrangement, the fixing member can be fixed to the heating part through the brackets. When fixing the light strip and the light guide ring on the induction cooker, the light strip and the light guide ring can be embedded in the first recess on the fixing member, so that the light strip and the light guide ring can be fixed to the heating part, thereby facilitating the light strip and the light guide ring to display the light circle at the position where the cookware should be placed in the heating area.

[0019] Since the light strip and the light guide ring are embedded in the first recess, when it is necessary to replace or maintain the light strip or the light guide ring, the light strip or the light guide ring can be directly taken out from the first recess, so that it is convenient to replace and maintain the light strip or the light guide ring.

[0020] In some embodiments of the present application, support protrusions are provided on the plurality of brackets. When the fixing member is connected to the plurality of brackets, the plurality of support protrusions are located on the side of the fixing member away from the heating area and are in contact with the fixing member. A plurality of second recesses are formed on the fixing member, and the plurality of second recesses penetrate the fixing member along the axial direction of the avoidance channel. The plurality of second recesses correspond to the plurality of support protrusions one by one. During the process of separating the fixing member from the plurality of brackets, one support protrusion can exit one second recess along the direction of the fixing member pointing to the heating area.

[0021] Through the above arrangement, when installing the fixing member on the plurality of brackets, the plurality of second recesses can be first located on the side of the plurality of support protrusions away from the heating area, and one second recess can be aligned with one support protrusion, and then the fixing member is moved along the direction of the heating part approaching the heating area, and the support protrusion is made to pass through the corresponding second recess, so as to move the fixing member from the side of the support protrusion away from the heating area to the side of the support protrusion close to the heating area, and then the fixing member is rotated along the circumferential direction of the avoidance channel to stagger the plurality of support protrusions from the plurality of second recesses, and finally the side of the fixing member away from the heating area is brought into contact with the side of the support protrusion close to the heating area, and the plurality of support protrusions provide support for the fixing member, thereby installing the fixing member on the plurality of brackets.

[0022] In this way, only by moving the fixing member along the arrangement direction of the heating part and the heating area, and rotating the fixing member circumferentially along the avoidance channel, the installation and disassembly of the fixing member on the bracket can be realized, so as to facilitate the installation and disassembly of the fixing member, and further facilitate the replacement or maintenance of the light strip and the light guide ring on the fixing member.

[0023] In some embodiments of the present application, a plurality of limiting parts are further arranged on the fixing member, and the plurality of limiting parts correspond to the plurality of second recessed parts one by one. The limiting part includes a guiding boss, and the guiding boss is arranged on the side wall of the fixing member away from the heating area. When the fixing member is connected to the plurality of brackets, the guiding boss is located on the side of the second recessed part away from the supporting protrusion, and the side surface of the guiding boss close to the supporting protrusion intersects with the side surface of the second recessed part away from the supporting protrusion. And / or, the limiting part includes a limiting boss, and the limiting boss is arranged on the side wall of the fixing member away from the heating area. When the fixing member is connected to the plurality of brackets, the limiting boss is located on the side of the supporting protrusion away from the second recessed part.

[0024] In this way, in the process of removing the fixing member from the plurality of brackets, through the guiding action of the guiding boss, it is convenient to align the plurality of supporting protrusions and the plurality of second recessed parts, so as to facilitate the removal of the fixing member from the plurality of brackets.

[0025] At the same time, the distance between the limiting boss and the second recessed part can be reasonably set so that the distance between the limiting boss and the second recessed part is relatively small, so that in the process of installing the fixing member on the plurality of brackets, the moving distance of the limiting boss is reduced, so as to facilitate the installation of the fixing member on the plurality of brackets. Thus, in the process of removing the fixing member from the plurality of brackets, due to the relatively small distance between the limiting boss and the second recessed part, the supporting protrusion and the second recessed part can be quickly aligned, and the supporting protrusion can pass through the second recessed part, so as to remove the fixing member from the plurality of brackets. In this way, the operation process of removing the fixing member from the plurality of brackets can be facilitated, and it is convenient to remove the fixing member from the plurality of brackets.

[0026] In some embodiments of the present application, heat dissipation holes are formed in the side wall of the fixing member away from the heating area, and the heat dissipation holes are communicated with the first recessed part.

[0027] In this way, the heat on the light strip can be dissipated from the first recessed part to the outside of the fixing member through the heat dissipation holes, so as to accelerate the heat dissipation speed of the light strip, ensure the working temperature of the light strip, prevent the light strip from malfunctioning due to overheating, thus ensuring the normal function of the light strip, and prolonging the service life of the light strip.

[0028] In the second aspect of the present application, a control method for an induction cooker is provided, including: judging whether the induction cooker is turned on; if the induction cooker is turned on, controlling the light strip to emit light so that the light emitted by the light strip passes through the light guide ring and forms an aperture in the heating area.

[0029] It should be noted that for the technical effects brought about by the implementation manner of the second aspect, reference may be made to the technical effects brought about by the corresponding implementation manner in the first aspect, which will not be elaborated here.

[0056] With the improvement of people's living standards, people have more and more choices for household appliances. As a cooking tool that does not require open flames for heating, the induction cooker has become a commonly used household appliance in people's daily lives.

[0057] Based on this, the present application provides an induction cooker, as Figure 1 shown, the induction cooker 1 includes a cooker body 11 and a cover plate 12. The cooker body 11 has a heating part 111. Specifically, as Figure 2 shown, the cooker body 11 includes a base 115 and a heating part 111. A cavity 116 with an opening on one side is formed in the base 115. The heating part is disposed in the cavity 116 and fixed to the base 115. Among them, the heating part 111 may include a heating disk and a heating coil disposed on the heating disk, and the heating disk is fixed to the base 115.

[0058] In addition, other components of the induction cooker 1 such as an electronic control board and a cooling fan are also disposed in the cavity 116.

[0059] As Figure 1As shown, the cover plate 12 is connected to the heating side of the furnace body 11, and a heatable light-transmitting area 121 is formed on the cover plate 12. Specifically, the cover plate is arranged at the opening of the cavity 116 and seals the opening of the cavity 116.

[0060] The heatable area 121 corresponds to the heating part 111. In this way, when using an induction cooker, most of the heat generated when the heating part 111 operates is concentrated in the heatable area 121, and thus a high-temperature area will be formed in the heatable area 121.

[0061] Therefore, when using the induction cooker 1, a cooking pot can be placed in the heatable area 121, and then power is supplied to the heating coil to cause the heating coil to generate a magnetic field. The magnetic lines of force in the magnetic field pass through the heatable area 121 and pass through the bottom of the cooking pot. After passing through the cooking pot, the magnetic lines of force will generate eddy currents at the bottom of the cooking pot, causing the bottom of the cooking pot to heat up rapidly, thereby achieving the purpose of heating the food in the cooking pot.

[0062] During the use of the induction cooker 1, there are often situations where the placement position of the cooking pot deviates from the position of the heating coil, resulting in uneven heating of the cooking pot.

[0063] Based on this, as Figure 2 、 Figure 3 shown, the induction cooker 1 further includes a light guide ring 131 and a light strip 132. The light guide ring 131 is arranged on the side of the heatable area 121 close to the heating part 111 and is connected to the furnace body 11. The orthographic projection of the light guide ring 131 on the cover plate 12 is located within the heatable area 121. The orthographic projection of the heating part 111 on the cover plate 12 is located within the orthographic projection of the light guide ring 131 on the cover plate 12. The light strip 132 extends around the circumference of the light guide ring 131 for one week and is attached to the light guide ring 131.

[0064] Exemplarily, the shape of the light guide ring 131 can be a circular ring or an elliptical ring.

[0065] In this way, the light emitted by the light strip 132 can enter the light guide ring 131 from the outer peripheral wall of the light guide ring 131 and then conduct within the light guide ring 131. Since the light guide ring 131 is annular, the light conducted to the heatable area 121 through the light guide ring 131 will form an aperture matching the shape of the light guide ring 131 in the heatable area 121. And since the orthographic projection of the heating part 111 on the cover plate 12 is located within the orthographic projection of the light guide ring 131 on the cover plate 12. Therefore, the high-temperature area formed by the heating part 111 in the heatable area 121 is located within the aperture, so that it is convenient for users to observe the position of the high-temperature area in the heatable area 121 and facilitates the use of the induction cooker 1 by users.

[0066] In some other examples, the light guide ring 131 can also be replaced by a light shielding plate, and light transmissive holes are formed in the light shielding plate. The light transmissive holes extend along the circumferential direction of the avoidance channel 1141 and surround the avoidance channel 1141 for one week. In this way, the light emitted by the light strip 132 can pass through the light transmissive holes and display an aperture matching the shape of the light transmissive holes on the heating area 121, so as to facilitate the formation of the aperture.

[0067] It should be noted that the display of the high-temperature area on the heating area 121 can be to display an aperture on the heating area 121 through the annular light guide ring 131.

[0068] Alternatively, the display of the high-temperature area on the heating area 121 can also be to display different shapes on the heating area 121 through light guide materials of other shapes. For example, a semi-circular annular light guide material can be used to display a semi-circular annular light band on the heating area 121, and special-shaped light guide materials, such as smiley face-shaped, pattern-shaped, etc., can be used to display graphics corresponding to the shapes of the light guide materials, such as smiley faces, patterns, etc. on the heating area 121, as long as it is ensured that the user can clearly observe the high-temperature area on the heating area 121. In this way, the aesthetics of the induction cooker 1 can be improved, thereby improving the user experience of using the induction cooker 1.

[0069] On this basis, the induction cooker 1 further includes a controller (not shown in the figure). The controller is configured to: determine whether the induction cooker 1 is turned on; if the induction cooker 1 is turned on, control the light strip 132 to emit light so that the light emitted by the light strip 132 passes through the light guide ring 131 and forms an aperture on the heating area 121.

[0070] It can be understood that the area where the aperture is displayed is the heating area 121.

[0071] In this way, the light strip 132 can display an aperture on the heating area 121 to remind the user to place the cookware within the aperture, that is, to place the cookware in the high-temperature area (i.e., the inner area of the aperture) of the induction cooker 1, so as to facilitate the user to quickly and accurately place the cookware in the correct position.

[0072] On this basis, in some embodiments, when the induction cooker 1 is turned on, the light strip 132 will continuously emit light until the induction cooker 1 is turned off. In this way, during the user's use of the induction cooker 1, an aperture can be continuously displayed on the heating area 121, enabling the user to observe the position of the high-temperature area on the heating area 121 at any time, which is convenient for the user to use the induction cooker 1.

[0073] Since the user may use the induction cooker 1 for a relatively long time, if the aperture is always in the lit state, that is, the light strip 132 continuously emits light, it will cause a large power consumption of the light strip 132, thereby increasing the use cost of the induction cooker 1.

[0074] To avoid the above problems, in some embodiments, the controller is further configured to: determine whether the cookware is located within the heating zone 121; if the cookware is located within the heating zone 121, control the light-emitting component to continue emitting light for a preset duration and then turn off. That is to say, during the process from when the induction cooker 1 is started to when the user places the cookware, the light strip 132 is always in the light-emitting state. After it is determined that the cookware is placed in the heating zone 121, the light strip 132 is controlled to continue emitting light for a preset duration and then turn off. Among them, the preset duration can be 5s, 6s, 7s, 8s, etc.

[0075] In this way, after the cookware is determined to be placed within the light circle, the controller will control the light strip 132 to turn off after the preset duration, so that it is possible to avoid the light strip 132 being always in the light-emitting state during the use of the induction cooker 1, thereby reducing the light-emitting duration of the light strip 132, reducing the power consumption of the light strip 132 during the operation of the induction cooker 1, and further reducing the power consumption of the induction cooker 1 to reduce the usage cost of the induction cooker 1.

[0076] In addition, since the light strip 132 generates heat when emitting light, and the induction cooker 1 also generates heat during operation, the heat generated by the light strip 132 and the heat generated by the induction cooker 1 will keep the light strip 132 in a relatively high-temperature environment, thus affecting the service life of the light strip 132. By controlling the light strip 132 to turn off after the preset duration through the controller, it is possible to reduce the light-emitting duration of the light strip 132 during the use of the induction cooker 1, thereby reducing the heat generated by the light strip 132 to lower the temperature around the light strip 132, and further extending the service life of the light strip 132.

[0077] It should be noted that if the light strip 132 is emitting light and after the cookware is placed on the induction cooker 1, if the light strip 132 is always in the light-emitting state and does not turn off, that is, the duration of the light strip 132 continuing to emit light is greater than the preset duration, it means that the position of the cookware on the induction cooker 1 deviates from the heating zone 121, and the user needs to adjust the placement position of the cookware on the induction cooker 1 until the cookware is placed in the heating zone 121.

[0078] During the operation of the induction cooker 1, when the cookware is completely within the light circle, the output power of the induction cooker 1 will be within the normal output power range (for example, the normal output power is greater than or equal to 800w and less than or equal to 1000w). In this way, the controller can judge whether the output power of the induction cooker 1 is within the normal output power range to determine whether the cookware is completely within the light circle. Specifically, when the output power of the induction cooker 1 is within the normal output power range, it means that the cookware is completely within the light circle. When the output power of the induction cooker 1 exceeds the normal output power range (for example, less than 800w), it means that the cookware deviates from the light circle.

[0079] It should be noted that other components installed in the induction cooker 1 also consume electric energy. That is, after the induction cooker 1 is turned on and no cookware is placed on the induction cooker 1, the output power of the induction cooker 1 is greater than zero.

[0080] It should also be noted that since the cookware that the induction cooker 1 can heat is ferromagnetic cookware such as iron pans, stainless steel pans, and special composite bottom pans, and it cannot heat cookware such as aluminum pans, alloy pans, glass pans, and ceramic pans, when aluminum pans, alloy pans, glass pans, ceramic pans, etc. are placed on the induction cooker 1, the output power of the induction cooker 1 will not change, that is, it is equivalent to no cookware being placed on the induction cooker 1.

[0081] During the user's use of the induction cooker 1, since the heating part 111 continuously heats the cookware, when the induction cooker 1 stops being used, there will be residual heat on the heating area 121, and the user may be scalded when touching the heating area 121 without noticing.

[0082] To avoid the above problems, in some embodiments, the induction cooker 1 further includes a temperature sensor (not shown in the figure). The temperature sensor is disposed between the heating area 121 and the heating part 111 and is in contact with the heating area 121 for detecting the actual temperature of the heating area 121. The controller is connected to the temperature sensor.

[0083] The controller is further configured to: if the induction cooker 1 is not turned on, obtain the actual temperature and determine whether the actual temperature is greater than or equal to a preset temperature; if the actual temperature is greater than or equal to the preset temperature, control the light strip 132 to emit light; if the actual temperature is less than the preset temperature, control the light strip 132 to turn off.

[0084] It should be noted that a control switch for starting or closing the induction cooker 1 is provided on the induction cooker 1. When the control switch is turned on, the instruction to turn on the induction cooker 1 is transmitted to the controller, and the controller controls the induction cooker 1 to turn on. At this time, the controller can obtain the turn-on information of the induction cooker 1. When the control switch is turned off, the instruction to turn off the induction cooker 1 is transmitted to the controller, and the controller controls the induction cooker 1 to turn off. At this time, the controller can obtain the turn-off information of the induction cooker 1.

[0085] It should be noted that if the actual temperature is less than the preset temperature, the light strip 132 is controlled to turn off. Specifically: if it is determined that the actual temperature is less than the preset temperature and the light strip 132 is in the off state, then control the light strip 132 to remain off; if it is determined that the actual temperature is less than the preset temperature and the light strip 132 is in the on state, then control the light strip 132 to turn off.

[0086] In this way, after the user uses the induction cooker 1, the user can determine whether the actual temperature of the heating zone 121 is greater than the preset temperature by observing whether the light strip 132 emits light, that is, whether there is an aperture displayed on the cover plate 12, so as to judge the temperature of the heating zone 121. When the aperture has brightness, it can remind the user that the temperature of the heating zone 121 is relatively high, thereby reducing the possibility of the user being scalded and improving the user experience of using the induction cooker 1.

[0087] Among them, the preset temperature can be 50°C, 55°C, 60°C, 65°C, 70°C, 80°C, etc.

[0088] Exemplarily, the controller continuously obtains the data of the actual temperature detected by the temperature sensor. In this way, the controller can timely obtain the change of the actual temperature of the heating zone 121, so that when the actual temperature of the heating zone 121 is less than the preset temperature, the light strip 132 can be timely turned off to reduce the power consumption of the light strip 132.

[0089] The controller can also obtain the data of the actual temperature detected by the temperature sensor as follows: obtain the actual temperature once at intervals of a preset acquisition duration. In this way, the acquisition frequency of the controller can be reduced to reduce the working load of the controller and extend the service life of the controller.

[0090] In some examples, the size of the actual temperature of the heating zone 121 can also be represented by changing the color of the light strip 132, so that the user can judge the actual temperature of the heating zone 121 according to the color of the aperture. For example, when the actual temperature of the heating zone 121 is greater than or equal to the preset temperature, the light strip 132 displays the first color, and when the actual temperature of the heating zone 121 is less than the preset temperature, the light strip 132 displays the second color, where the first color is different from the second color. Exemplarily, the first color is red and the second color is green, or the first color is yellow and the second color is blue.

[0091] On the above basis, since the cookware may move during the use of the induction cooker 1, the cookware may deviate from the heating zone 121. At this time, in order to timely remind the user whether the cookware deviates from the heating zone 121, in some embodiments, the controller is further configured to: judge whether the light strip 132 is extinguished; if the light strip 132 is extinguished, then judge again whether the cookware is located in the heating zone 121; if the cookware deviates from the heating zone 121, control the light strip 132 to emit light.

[0092] That is to say, after the cookware is located within the heating zone 121, during the use of the cookware and the induction cooker 1, the position sensor continuously detects the position information of the cookware and transmits the detected real-time position information to the controller. The controller determines in real time whether the cookware deviates from the heating zone 121 based on the position information. If the cookware deviates from the heating zone 121, the controller controls the light strip 132 to emit light, so that the light strip 132 displays an aperture on the heating zone 121.

[0093] In this way, during the operation of the induction cooker 1, if the cookware deviates from the heating zone 121, the controller will control the light strip 132 to emit light, thereby reminding the user that the cookware has deviated from the heating zone 121. Thus, the user can, based on the reminder of the light strip 132, re-place the cookware within the heating zone 121, thereby ensuring the heating effect of the induction cooker 1 on the cookware.

[0094] In addition, during the use of the induction cooker 1 by the user, it may be necessary to remove the cookware from the induction cooker 1 and then re-place it on the induction cooker 1. Since the controller will control the light strip 132 to emit light when the cookware deviates from the heating zone 121, during the process of the user re-placing the cookware on the induction cooker 1, the light strip 132 will emit light and display an aperture on the heating zone 121, thereby reminding the user of the position of the high-temperature area on the heating zone 121, thus facilitating the user to re-place the cookware within the cookware.

[0095] On this basis, after the cookware is re-placed within the heating zone 121, the controller still continuously obtains the position information of the cookware. If the controller determines based on the position information that the cookware is located within the heating zone 121, it controls the light strip 132 to continue emitting light for a preset duration and then turn off. If the controller determines based on the position information that the cookware still deviates from the heating zone 121, it controls the light strip 132 to continue to maintain the lighting state.

[0096] To further improve the user experience of using the induction cooker 1, in some embodiments, the controller is further configured to: obtain the output power of the induction cooker 1; adjust the change state of the light strip 132 according to the change in the output power.

[0097] In this way, the user can judge the magnitude of the output power of the induction cooker 1 based on the different change states of the light strip 132, thus facilitating the user to judge the magnitude of the output power of the induction cooker 1, facilitating the user to adjust the output power of the induction cooker 1, and further improving the user experience of using the induction cooker 1.

[0098] Wherein, the change state of the light strip 132 is at least one of color change and brightness change.

[0099] Exemplarily, when the change state of the light strip 132 is a color change, different colors can be emitted by the light strip 132 according to the change in the output power, and different colors correspond to different output powers.

[0100] For example, the induction cooker 1 has three gears, each gear corresponding to an output power of the induction cooker 1, and an output power corresponding to one of the three colors red, yellow, and blue. Specifically, the three gears of the induction cooker 1 are the first gear, the second gear, and the third gear respectively. When the output power of the induction cooker 1 is at the first gear, the light strip 132 emits red light. When the output power of the induction cooker 1 is at the second gear, the light strip 132 emits yellow light. When the output power of the induction cooker 1 is at the third gear, the light strip 132 emits blue light.

[0101] Exemplarily, when the change state of the light strip 132 is a brightness change, the brightness of the light strip 132 can be gradually enhanced as the output power of the induction cooker 1 gradually increases, that is, the output power of the induction cooker 1 is positively correlated with the brightness of the light strip 132; or the brightness of the light strip 132 can be gradually weakened as the output power of the induction cooker 1 gradually increases, that is, the output power of the induction cooker 1 is negatively correlated with the brightness of the light strip 132.

[0102] It should be noted that when the induction cooker 1 is at different gears, the normal output power range will also change accordingly, that is, at different gears, the controller can judge whether the cookware is completely within the light circle according to the normal output power range corresponding to different gears.

[0103] On the above basis, in some embodiments, as Figure 4 、 Figure 5 shown, the furnace body 11 includes a plurality of brackets 113 and fixing members 114. The plurality of brackets 113 are arranged at intervals along the circumferential direction of the heat conduction channel on the heating part 111. Specifically, the plurality of brackets 113 can be fixed to the heating plate by fasteners such as bolts and screws, or can be fixed to the heating plate by means of clamping, welding, riveting, etc.

[0104] The fixing member 114 is arranged on the plurality of brackets 113. An avoidance channel 1141 and a first recess 1142 are formed on the fixing member 114. The orthographic projection of the heating part 111 in the heating area 121 is located within the orthographic projection of the avoidance channel 1141 in the heating area 121. The first recess 1142 is located on the side surface of the fixing member 114 close to the heating area 121. As Figure 6 shown, the light strip 132 and the light guide ring 131 are embedded in the first recess 1142.

[0105] In some examples, the light strip 132 and the light guide ring 131 can be connected to the inner wall of the first recess 1142 by an adhesive means, so that the light strip 132 and the light guide ring 131 can be more stably fixed in the first recess 1142.

[0106] In some other examples, the light strip 132 and the light guide ring 131 can also be connected to the inner wall of the first recess 1142 by means of screwing, clamping, riveting, etc., so that the light strip 132 and the light guide ring 131 can be more stably fixed in the first recess 1142.

[0107] Through the above settings, the fixing member 114 can be fixed to the heating part 111 through the bracket 113. When fixing the light strip 132 and the light guide ring 131 on the induction cooker 1, the light strip 132 and the light guide ring 131 can be embedded in the first recess 1142 on the fixing member 114, so that the light strip 132 and the light guide ring 131 can be fixed to the heating part 111, thereby facilitating the light strip 132 and the light guide ring 131 to display the light ring at the position where the cookware should be placed in the heating area 121.

[0108] Since the light strip 132 and the light guide ring 131 are embedded in the first recess 1142, when it is necessary to replace the light strip 132 or the light guide ring 131, or perform maintenance on the light strip 132 or the light guide ring 131, the light strip 132 or the light guide ring 131 can be directly taken out from the first recess 1142, so that it is convenient to replace and maintain the light strip 132 or the light guide ring 131.

[0109] In addition, the side wall and the bottom wall of the first recess 1142 can block the light conducted by the light guide ring 131, so that most of the light is transmitted from the side of the light guide ring 131 close to the heating area 121 to the heating area 121, thus avoiding the light conducted from the light guide ring 131 from being too scattered and resulting in more light irradiating inside the light ring, thereby affecting the brightness inside the light ring, and ensuring the display effect of the light ring transmitted by the light guide ring 131 on the heating area 121.

[0110] Exemplarily, the light strip 132, the light guide ring 131 and the fixing member 114 can all be arranged in the cavity 116.

[0111] Exemplarily, the light strip 132, the light guide ring 131 and the fixing member 114 can also be arranged outside the cavity 116.

[0112] In some examples, such as Figure 7 , Figure 8 as shown, the cover plate 12 includes a panel 122 and a light-transmitting plate 123. An installation hole 1221 is formed on the panel 122, the installation hole 1221 corresponds to the heating part 111, the light-transmitting plate 123 is arranged in the installation hole 1221, and the thickness direction of the light-transmitting plate 123 is the same as the thickness direction of the panel 122.

[0113] The thickness of the light-transmitting plate 123 is less than that of the panel 122, and the surface of the light-transmitting plate 123 on the side away from the heating part 111 and the surface of the panel 122 on the side away from the heating part 111 are in the same plane, so as to form a mounting groove 124 on the side of the light-transmitting plate 123 close to the heating part 111. As Figure 8 shown, at least part of the light strip 132, the light guide ring 131 and the fixing member 114 are located in the mounting groove 124.

[0114] Among them, the material of the panel 122 can be ceramic, glass, stainless steel, etc., and the material of the light-transmitting plate 123 can be glass-ceramics. Glass-ceramics has good light-transmitting performance, and has the characteristics of high temperature resistance and low expansion, which is convenient for the heating part 111 to heat the cookware.

[0115] In some examples, the fixing member 114 can be a fixing ring. At this time, the light strip 132 and the light guide ring 131 can be directly fixed on the surface of the fixing member 114 on the side close to the heating area 121. Specifically, the light strip 132 and the light guide ring 131 can be pasted on the surface of the fixing member 114 close to the heating area 121, or can be connected to the surface of the fixing member 114 close to the heating area 121 by a snap connection method.

[0116] In addition, as Figure 9 shown, the fixing member 114 further includes a first fixing ring 1143, a support plate 114A and a second fixing ring 1144. The first fixing ring 1143 is arranged on a plurality of brackets 113. The support plate 114A is connected to the side of the first fixing ring 1143 away from the cover plate 12 and surrounds the first fixing ring 1143 for one week. The second fixing ring 1144 is located on the side of the support plate 114A close to the cover plate 12, and the second fixing ring 1144 is sleeved on the outer side of the first fixing ring 1143. There is a gap between the outer peripheral surface of the first fixing ring 1143 and the inner peripheral surface of the second fixing ring 1144, so that the outer peripheral surface of the first fixing ring 1143, the inner peripheral surface of the second fixing ring 1144 and the support plate 114A can enclose a first recessed part 1142.

[0117] Among them, the second fixing ring 1144 can be fixed to the cover plate 12 or can be fixedly connected to the support plate 114A. When the second fixing ring 1144 can be fixed to the cover plate 12, the second fixing ring 1144 can be in contact with the support plate 114A or can have a small gap with the support plate 114A. At this time, when replacing or maintaining the light strip 132 and the light guide ring 131, only the first fixing ring 1143, the light strip 132 and the light guide ring 131 can be disassembled or installed from the bracket 113, so that the process of removing the light strip 132 and the light guide ring 131 from the fixing member 114 can be simplified, thereby facilitating the replacement or maintenance of the light strip 132 and the light guide ring 131.

[0118] In addition, the support plate 114A can be integrally provided with the first fixing ring 1143. At this time, when replacing or maintaining the light strip 132 and the light guide ring 131, the first fixing ring 1143, the support plate 114A, the light strip 132, and the light guide ring 131 can be detached from or installed on the bracket 113. The support plate 114A can also be integrally provided with the second fixing ring 1144.

[0119] Since the fixing member 114 is located on the side of the heating area 121 close to the heating part 111, when installing the fixing member 114 on a plurality of brackets 113, it will be blocked by the cover plate 12, and the fixing member 114 can only be installed on a plurality of brackets 113 along the direction in which the heating part 111 approaches the heating area 121.

[0120] To facilitate the setting of the fixing member 114 on a plurality of brackets 113, in some embodiments, as Figure 10 , Figure 11 shown, a plurality of brackets 113 are provided with support protrusions 1131. When the fixing member 114 is connected to a plurality of brackets 113, the plurality of support protrusions 1131 are located on the side of the fixing member 114 away from the heating area 121 and are in contact with the fixing member 114. A plurality of second recesses 1145 are formed in the fixing member 114, and the plurality of second recesses 1145 penetrate through the fixing member 114 along the axial direction of the avoidance channel 1141. The plurality of second recesses 1145 correspond to the plurality of support protrusions 1131 one by one. During the separation of the fixing member 114 from the plurality of brackets 113, one support protrusion can exit one second recess 1145 along the direction in which the fixing member 114 points to the heating area 121.

[0121] Exemplarily, a plurality of brackets 113 are located within the avoidance channel 1141. At this time, the support protrusions 1131 can be located on the side of the bracket 113 away from the axis of the avoidance channel 1141. At this time, the second recesses 1145 are located on the side wall of the fixing member 114 close to the axis of the avoidance channel 1141.

[0122] Alternatively, a plurality of brackets 113 are located outside the fixing member 114. At this time, the support protrusions 1131 can be located on the side of the bracket 113 close to the axis of the avoidance channel 1141. At this time, the second recesses 1145 are located on the side wall of the fixing member 114 away from the axis of the avoidance channel 1141.

[0123] With the above settings, when the fixing member 114 is arranged on the plurality of brackets 113, the plurality of second recesses 1145 can be first located on the side of the plurality of support protrusions 1131 away from the heating area 121, and one second recess 1145 is aligned with one support protrusion 1131. Then, the fixing member 114 is moved along the heating part 111 in the direction approaching the heating area 121, and the support protrusion 1131 is made to pass through the corresponding second recess 1145, so as to move the fixing member 114 from the side of the support protrusion 1131 away from the heating area 121 to the side of the support protrusion 1131 close to the heating area 121. Then, the fixing member 114 is rotated circumferentially along the avoidance channel 1141, so that the plurality of support protrusions 1131 are staggered from the plurality of second recesses 1145. Finally, the side of the fixing member 114 away from the heating area 121 is abutted against the side of the support protrusion 1131 close to the heating area 121, and the plurality of support protrusions 1131 provide support for the fixing member 114, thereby mounting the fixing member 114 on the plurality of brackets 113.

[0124] In this way, only by moving the fixing member 114 along the arrangement direction of the heating part 111 and the heating area 121, and rotating the fixing member 114 circumferentially along the avoidance channel 1141, the installation and disassembly of the fixing member 114 on the bracket 113 can be realized, so that the installation and disassembly of the fixing member 114 are facilitated, and further the replacement or maintenance of the light strip 132 and the light guide ring 131 on the fixing member 114 are facilitated.

[0125] In order to facilitate the support protrusion 1131 to pass through the corresponding second recess 1145 and enable the support protrusion 1131 to support the fixing member 114, in some embodiments, as Figure 12 、 Figure 13 shown, a plurality of limiting parts 1146 are further arranged on the fixing member 114, and the plurality of limiting parts 1146 correspond to the plurality of second recesses 1145 one by one. As Figure 14 shown, the limiting part 1146 includes a guiding boss 114B, and the guiding boss 114B is arranged on the side wall of the fixing member 114 away from the heating area 121. When the fixing member 114 is connected to the plurality of brackets 113, the guiding boss 114B is located on the side of the second recess 1145 away from the support protrusion 1131, and the side surface of the guiding boss 114B close to the support protrusion 1131 intersects with the side surface of the second recess 1145 away from the support protrusion 1131.

[0126] With the above settings, during the process of removing the fixing member 114 from the plurality of brackets 113, the fixing member 114 can be rotated in the circumferential direction of the avoidance channel 1141 and along the direction in which the guiding boss 114B points to the supporting protrusion 1131. During this process, the guiding boss 114B will rotate synchronously with the fixing member 114 until the guiding boss 114B abuts against the supporting protrusion 1131. At this time, the supporting protrusion 1131 is aligned with the second recess 1145. The fixing member 114 can be moved in the direction away from the heating area 121, so that the supporting protrusion 1131 passes through the second recess 1145 along the direction in which the fixing member 114 approaches the heating area 121, and then the supporting protrusion 1131 is separated from the fixing member 114, thereby removing the fixing member 114 from the plurality of brackets 113.

[0127] In this way, during the process of removing the fixing member 114 from the plurality of brackets 113, through the guiding action of the guiding boss 114B, it is possible to facilitate the alignment of the plurality of supporting protrusions 1131 and the plurality of second recesses 1145, so as to facilitate the removal of the fixing member 114 from the plurality of brackets 113.

[0128] In order to further facilitate the removal of the fixing member 114 from the plurality of brackets 113, in some embodiments, as Figure 13 shown, the limiting portion 1146 includes a limiting boss 114C. The limiting boss 114C is arranged on the side wall of the fixing member 114 away from the heating area 121. When the fixing member 114 is connected to the plurality of brackets 113, the limiting boss 114C is located on the side of the supporting protrusion 1131 away from the second recess 1145.

[0129] With the above settings, during the process of installing the fixing member 114 on the plurality of brackets 113, after the supporting protrusion 1131 passes through the second recess 1145, the fixing member 114 can be rotated in the circumferential direction of the avoidance channel 1141 and along the direction in which the supporting protrusion 1131 approaches the limiting boss 114C until the supporting protrusion 1131 abuts against the limiting boss 114C. At this time, the supporting protrusion 1131 is located on the side of the fixing member 114 away from the heating area 121, so that the supporting protrusion 1131 supports the fixing member 114.

[0130] In this way, the distance between the limiting boss 114C and the second recess 1145 can be reasonably set so that the distance between the limiting boss 114C and the second recess 1145 is small, so as to reduce the moving distance of the limiting boss 114C during the process of installing the fixing member 114 on the plurality of brackets 113, so as to facilitate the installation of the fixing member 114 on the plurality of brackets 113.

[0131] During the process of removing the fixing member 114 from the plurality of brackets 113, since the distance between the limiting boss 114C and the second recess 1145 is small, the supporting protrusion 1131 can be quickly aligned with the second recess 1145, and the supporting protrusion 1131 can pass through the second recess 1145, thereby removing the fixing member 114 from the plurality of brackets 113. In this way, the operation process of removing the fixing member 114 from the plurality of brackets 113 can be facilitated, and it is convenient to remove the fixing member 114 from the plurality of brackets 113.

[0132] In some examples, as Figure 13 shown, a third recess 1147 is formed on the surface of the fixing member 114 on the side away from the heating area 121, and the third recess 1147 is located on the side of the limiting boss 114C close to the second recess 1145. In this way, when the fixing member 114 is supported by the supporting protrusion 1131, at least part of the supporting protrusion 1131 can extend into the third recess 1147, so that the third recess 1147 can limit the supporting protrusion 1131 to prevent the supporting protrusion 1131 from moving relative to the fixing member 114, thereby enabling the supporting protrusion 1131 to support the fixing member 114 more stably.

[0133] Since the light strip 132 generates heat by itself during operation and the light strip 132 is arranged in the first recess 1142, it is necessary to dissipate heat from the light strip 132.

[0134] In some embodiments, as Figure 14 shown, heat dissipation holes 1148 are formed in the side wall of the fixing member 114 away from the heating area 121, and the heat dissipation holes 1148 communicate with the first recess 1142.

[0135] Exemplarily, the number of the heat dissipation holes 1148 can be one or multiple, such as two, three, four, etc.

[0136] Exemplarily, when the number of the heat dissipation holes 1148 is one, the heat dissipation hole 1148 can extend along the circumferential direction of the avoidance channel 1141.

[0137] Exemplarily, when the number of the heat dissipation holes 1148 is multiple, the multiple heat dissipation holes 1148 can be arranged on the fixing member 114 along the circumferential direction of the avoidance channel 1141, wherein the multiple heat dissipation holes 1148 can be evenly arranged or unevenly arranged.

[0138] In this way, the heat on the light strip 132 can be dissipated from the first recess 1142 to the outside of the fixing member 114 through the heat dissipation holes 1148, thereby accelerating the heat dissipation speed of the light strip 132, ensuring the working temperature of the light strip 132, preventing the light strip 132 from malfunctioning due to overheating, thus ensuring the normal function of the light strip 132 and extending the service life of the light strip 132.

[0139] The embodiments in the present application also provide a method for controlling an induction cooker 1, as Figure 15 shown, including:

[0140] S1: Determine whether the induction cooker 1 is turned on;

[0141] S2: If the induction cooker 1 is turned on, control the light strip 132 to emit light so that the light emitted by the light strip 132 passes through the light guide ring 131 and forms an aperture in the heating area 121.

[0142] In this way, the high-temperature area on the induction cooker 1 can be displayed through the aperture, thus facilitating the user to observe the position of the high-temperature area on the heating area 121 and facilitating the user's use of the induction cooker 1.

[0143] On this basis, in some embodiments, as Figure 16 shown, the control method of the induction cooker 1 further includes:

[0144] S10: Determine whether the cookware is located in the heating area 121;

[0145] S20: If the cookware is located in the heating area 121, control the light strip 132 to continue emitting light for a preset duration and then turn off.

[0146] In this way, the light-emitting duration of the light strip 132 can be reduced to reduce the power consumption of the light strip 132 during the operation of the induction cooker 1, and further reduce the power consumption of the induction cooker 1 to reduce the usage cost of the induction cooker 1.

[0147] On this basis, in some embodiments, as Figure 17 shown, the control method of the induction cooker 1 further includes:

[0148] S11: If the induction cooker 1 is not turned on, obtain the actual temperature;

[0149] S21: Determine whether the actual temperature is greater than or equal to the preset temperature;

[0150] S31: If the actual temperature is greater than or equal to the preset temperature, control the light strip 132 to emit light;

[0151] If the actual temperature is less than the preset temperature, control the light strip 132 to turn off.

[0152] In this way, the user can be reminded that the temperature of the heating area 121 is relatively high through the brightness of the aperture, so as to reduce the possibility of the user being scalded, thereby improving the user experience of using the induction cooker 1.

[0153] On this basis, in some embodiments, such as Figure 18 shown, the control method of the induction cooker 1 further includes:

[0154] S12: Determine whether the light strip 132 is extinguished;

[0155] S22: If the light strip 132 is extinguished, then determine again whether the cookware is located within the heating area 121;

[0156] S32: If the cookware deviates from the heating area 121, control the light strip 132 to emit light.

[0157] In this way, by controlling the light strip 132 to emit light, the user can be reminded that the cookware has deviated from the heating area 121, so that the user can put the cookware back into the heating area 121 according to the reminder of the light strip 132.

[0158] Exemplarily, as Figure 19 shown, the preset temperature can be 60 °C, and the preset duration can be 5 s. Then the whole process of the control method of the induction cooker 1 is as follows:

[0159] Determine whether the induction cooker 1 is turned on;

[0160] If the induction cooker 1 is turned on, control the light strip 132 to emit light so that the light emitted by the light strip 132 passes through the light guide ring 131 and forms an aperture in the heating area 121;

[0161] Determine whether the cookware is located within the heating area 121;

[0162] If the cookware is located within the heating area 121, control the light-emitting component to continue emitting light for 5 s and then go out;

[0163] Determine whether the light strip 132 is extinguished;

[0164] If the light strip 132 is extinguished, then determine again whether the cookware is located within the heating area 121;

[0165] If the cookware deviates from the heating area 121, control the light strip 132 to emit light;

[0166] If the induction cooker 1 is not turned on, obtain the actual temperature and determine whether the actual temperature is greater than or equal to 60 °C;

[0167] If the actual temperature is greater than or equal to 60 °C, control the light strip 132 to emit light;

[0168] If the actual temperature is less than 60 °C, control the light strip 132 to go out.

[0169] Among them, when determining whether the cookware is located in the heating area 121, if the cookware deviates from the heating area 121, the control light strip 132 is controlled to emit light, and the position information of the cookware is obtained again, and it is determined whether the cookware is located within the heating area 121;

[0170] In some embodiments, in order to further improve the user experience of using the induction cooker 1, such as Figure 20 shown, the control method of the induction cooker 1 further includes:

[0171] S13: Obtain the output power of the induction cooker 1;

[0172] S23: Adjust the change state of the light strip 132 according to the change of the output power.

[0173] This can facilitate the user to judge the magnitude of the output power of the induction cooker 1, so as to facilitate the user to adjust the output power of the induction cooker 1, thereby further improving the user experience of using the induction cooker 1.
