Description

Technical Field

[0001] This application relates to the field of control technology for far-infrared heating devices, and more particularly to a control method, heating device, and storage medium for a heating device. Background Technology

[0002] Far-infrared ovens, also known as far-infrared barbecue grills, are environmentally friendly, smokeless infrared electric barbecue grills. Currently, the most common and widely used far-infrared oven on the market is the carbon fiber barbecue grill. Carbon fiber barbecue grills use carbon fiber filaments for heating; these filaments are vacuum-sealed within a quartz tube to form a carbon fiber tube. Their biggest advantage is that they allow for even heating of the grill pan.

[0003] However, carbon fiber tubes generate extremely high temperatures, typically exceeding 1000 degrees Celsius (°C), which increases the risks associated with using carbon fiber grills. For example, excessively high temperatures can damage the grill pan material, potentially leading to the destruction of the entire grill, or the exposed carbon fiber tubes can cause injury to users due to excessive heat.

[0004] Therefore, how to improve the safety factor of far-infrared furnaces during use remains a problem that needs to be solved. Summary of the Invention

[0005] This application provides a control method for a heating device, a heating device, and a storage medium, which improves the safety factor of far-infrared furnaces during use.

[0006] In a first aspect, this application provides a method for controlling a heating device, comprising:

[0007] Upon receiving an electrical signal from the temperature acquisition device, the current temperature acquired by the temperature acquisition device is determined based on the electrical signal.

[0008] Based on the adjustment relationship between temperature and heating mode, the adjusted heating mode corresponding to the current temperature is determined. In the adjustment relationship between temperature and heating mode, the higher the temperature, the shorter the heating duration and / or the lower the heating power in the corresponding heating mode.

[0009] Adjust the heating mode of the far-infrared heating tube in the heating device according to the adjusted heating mode.

[0010] In one implementation, determining the adjusted heating mode corresponding to the current temperature based on the adjustment relationship between temperature and heating mode includes:

[0011] When the current temperature is determined to be greater than or equal to the first temperature, the adjusted heating mode is determined to be reducing the heating power of the far-infrared heating tube to a preset power range based on the adjustment relationship between temperature and heating mode.

[0012] When the current temperature is determined to be greater than or equal to the second temperature, the adjusted heating mode is determined to stop heating every fixed time interval based on the adjustment relationship between temperature and heating mode.

[0013] When the current temperature is determined to be greater than or equal to the third temperature, the adjusted heating mode is determined to be "stop heating" based on the adjustment relationship between temperature and heating mode.

[0014] Wherein, the first temperature is less than the second temperature, and the second temperature is less than the third temperature.

[0015] In one embodiment, adjusting the heating mode of the far-infrared heating tube according to the adjusted heating mode includes:

[0016] When the adjusted heating mode is to reduce the heating power of the far-infrared heating tube to a preset power range, a first signal is output. The first signal is used to reduce the heating power of the far-infrared heating tube to a preset power range.

[0017] When the adjusted heating mode stops heating at fixed intervals, a second signal is output. The second signal is used to control the far-infrared heating tube to stop heating at fixed intervals when it is in the heating state.

[0018] When the adjusted heating mode is set to stop heating, a third signal is output, which is used to control the far-infrared heating tube to stop working.

[0019] In one embodiment, after outputting the third signal, the method further includes:

[0020] After a fixed duration, when it is determined that the difference between the current temperature collected by the temperature acquisition device and the third temperature is less than or equal to a preset difference, a fourth signal is output. The fourth signal is used to control the entire heating device to stop working.

[0021] In one embodiment, before receiving the electrical signal sent by the temperature acquisition device, the method further includes:

[0022] It receives power-on commands and controls the display screen to show multiple functions.

[0023] When the execution instruction for the first function is received, the running mode corresponding to the first function is executed.

[0024] The control method for the heating device provided in this embodiment determines the corresponding adjusted heating mode based on the current temperature collected by the temperature acquisition device, and adjusts the heating mode of the far-infrared heating tube in the heating device according to the adjusted heating mode. It should be noted that in the adjustment relationship between temperature and heating mode, the higher the temperature, the shorter the heating duration and / or the lower the heating power in the corresponding heating mode. That is, when the far-infrared heating tube is running at high temperatures, the temperature is controlled in a timely manner by reducing the heating power and heating duration, preventing the far-infrared heating tube from continuously operating at high temperatures and causing injury to the user or damage to the equipment itself, thereby improving the safety factor of the heating device (such as a far-infrared furnace) during use.

[0025] Secondly, this application provides a heating device, including: a heating element, a temperature acquisition device, a control device, and a mounting base; wherein the temperature acquisition device is signal-connected to the control device;

[0026] The heating device includes a heating plate and a far-infrared heating tube. The far-infrared heating tube is disposed on the mounting base, and the heating plate is laid on the side of the far-infrared heating tube away from the mounting base.

[0027] The temperature acquisition device is disposed between the heating plate and the far-infrared heating tube, and is used to acquire temperature signals, convert the temperature signals into electrical signals, and send them to the control device.

[0028] The control device is used to perform the control method for the heating device as described in the first aspect.

[0029] In one embodiment, the far-infrared heating tube in the heating device is a disc-shaped heating tube, and the heating device also includes an isolation plate;

[0030] The isolation plate is disposed on the outer side of the disc-shaped heating tube;

[0031] The isolation plate is provided with a thermal fuse. When the thermal fuse melts, the far-infrared heating tube stops heating.

[0032] In one embodiment, the control device includes a controller and a heat-generating driver;

[0033] The heating driver is used to drive the far-infrared heating tube to generate heat when it is working.

[0034] The controller is used to control the output signal of the heating driver, and the output signal is used to control the heating power of the far-infrared heating tube.

[0035] In one embodiment, the heating device further includes a reflector plate, which is laid on the side of the far-infrared heating tube near the mounting base.

[0036] The heating device provided in the embodiments of this application includes a heating element, a temperature acquisition device, a control device, and a mounting base. The heating element includes a heating plate and a far-infrared heating tube. The far-infrared heating tube is disposed on the mounting base, and the heating plate is placed on the side of the far-infrared heating tube away from the mounting base. The heating plate can be understood as a baking tray, which will come into direct contact with the user. The temperature acquisition device is disposed between the heating plate and the far-infrared heating tube, and is used to acquire temperature signals and convert the temperature signals into electrical signals. That is, the temperature acquisition device is used to acquire the temperature between the heating plate and the far-infrared heating tube. The control device is used to first determine the current temperature based on the electrical signal, and then determine the adjusted heating mode of the far-infrared heating tube based on the adjustment relationship between temperature and heating mode. It should be noted that in the adjustment relationship between temperature and heating mode, the higher the temperature, the shorter the heating duration and / or the lower the heating power in the corresponding heating mode.

[0037] In other words, the higher the current temperature (the temperature between the heating plate and the far-infrared heating tube) collected by the temperature acquisition device, the higher the control device will control the far-infrared heating tube to reduce its heating power and / or reduce its heating time, thereby preventing the heating plate from overheating. Therefore, the heating device provided by the embodiments of this application has a high safety factor, solving the problem of how to improve the safety factor of heating devices (such as far-infrared furnaces) during use.

[0038] Thirdly, this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the control method for the heating device as described in the first aspect.

[0039] Fourthly, this application provides a computer program product, including a computer program that, when executed by a processor, implements the control method for the heating device as described in the first aspect.

[0040] In summary, the control method for a heating device provided in the embodiments of this application includes: upon receiving an electrical signal from a temperature acquisition device, determining the current temperature acquired by the temperature acquisition device based on the electrical signal; determining an adjusted heating mode corresponding to the current temperature based on the adjustment relationship between temperature and heating mode, wherein, in the adjustment relationship between temperature and heating mode, the higher the temperature, the shorter the heating duration and / or the lower the heating power in the corresponding heating mode; and adjusting the heating mode of the far-infrared heating tube in the heating device according to the adjusted heating mode.

[0041] The control method for this heating device can be understood as a control unit applied to the heating device, which communicates with a temperature acquisition device within the heating device. The temperature acquisition device collects the air temperature around the far-infrared heating tube in the heating device (such as the far-infrared furnace described above). The control unit determines the corresponding adjusted heating mode based on the current temperature collected by the temperature acquisition device, and adjusts the heating mode of the far-infrared heating tube in the heating device according to this adjusted heating mode. It should be noted that in the relationship between temperature and heating mode, the higher the temperature, the shorter the heating duration and / or the lower the heating power in the corresponding heating mode. That is, when the far-infrared heating tube operates at high temperatures, the temperature is controlled in a timely manner by reducing the heating power and heating duration, preventing continuous high-temperature operation of the far-infrared heating tube from causing injury to users or damage to the equipment itself, thereby improving the safety factor of the heating device (such as the far-infrared furnace) during use.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0063] Currently, the most common and widely used far-infrared oven on the market is the carbon fiber grill. Carbon fiber grills use carbon fiber filaments for heating, which are vacuum-sealed within a quartz tube to form a carbon fiber tube. Its biggest advantage is that it allows for even heating of the grill pan. However, the carbon fiber tube generates extremely high temperatures, typically exceeding 1000 degrees Celsius, which increases the risks associated with using a carbon fiber grill. For example, excessively high temperatures can damage the grill pan material, potentially leading to damage to the entire grill, or the exposed carbon fiber tubes could cause injury to the user due to excessive heat.

[0064] Based on this, this application provides a control method for a heating device, a heating device, and a storage medium. The control method for the heating device includes: upon receiving an electrical signal from a temperature acquisition device, determining the current temperature acquired by the temperature acquisition device based on the electrical signal; determining an adjusted heating mode corresponding to the current temperature based on the adjustment relationship between temperature and heating mode, wherein, in the adjustment relationship between temperature and heating mode, the higher the temperature, the shorter the heating duration and / or the lower the heating power in the corresponding heating mode; and adjusting the heating mode of the far-infrared heating tube in the heating device according to the adjusted heating mode.

[0065] The control method for this heating device can be understood as a control unit applied to the heating device, which communicates with a temperature acquisition device within the heating device. The temperature acquisition device collects the air temperature around the far-infrared heating tube in the heating device (such as the far-infrared furnace described above). The control unit determines the corresponding adjusted heating mode based on the current temperature collected by the temperature acquisition device, and adjusts the heating mode of the far-infrared heating tube in the heating device according to this adjusted heating mode.

[0066] It should be noted that in the relationship between temperature and heating mode, the higher the temperature, the shorter the heating duration and / or the lower the heating power in the corresponding heating mode. That is, when the far-infrared heating tube is running at high temperature, the temperature is controlled in a timely manner by reducing the heating power and heating duration to prevent the far-infrared heating tube from running at a high temperature continuously, which could cause injury to the user or damage to the equipment itself, thereby improving the safety factor of heating equipment (such as far-infrared furnace) during use.

[0067] The control method for the heating device provided in this application is applied to electronic devices, such as control devices for remotely controlling heating devices, control devices within heating devices, etc. Figure 1 This is a schematic diagram illustrating the application of the control method for the heating device provided in this application. In the diagram, after receiving an electrical signal from a temperature acquisition device, the electronic device determines the current temperature acquired by the temperature acquisition device based on the electrical signal. Then, based on the adjustment relationship between temperature and heating mode, it determines the adjusted heating mode corresponding to the current temperature. The heating mode of the far-infrared heating tube in the heating device is then adjusted according to the adjusted heating mode.

[0068] Please see Figure 2 One embodiment of this application provides a control method for a heating device, comprising:

[0069] S210: After receiving an electrical signal from the temperature acquisition device, determine the current temperature acquired by the temperature acquisition device based on the electrical signal.

[0070] In an optional embodiment, the heating device 100 in the heating device 10 includes a heating plate 110 and a far-infrared heating tube 120. The far-infrared heating tube 120 is disposed on a mounting base 400, and the heating plate 110 is laid on the side of the far-infrared heating tube 120 away from the mounting base 400. The heating plate 110 is, for example, a ceramic plate. The side of the heating plate 110 away from the far-infrared heating tube 120 will be in direct contact with the outside environment. Therefore, it is necessary to control the heating of the far-infrared heating tube 120 to control the surface temperature of the heating plate 110 and prevent injury from high-temperature contact.

[0071] A temperature acquisition device 200 is disposed between the heating plate 110 and the far-infrared heating tube 120 to acquire temperature signals, convert the temperature signals into electrical signals, and send the electrical signals to the control device 300 in the heating device 10. For example, the temperature acquisition device 200 is a thermocouple disposed between the heating plate 110 and the far-infrared heating tube 120. The thermocouple is located at the center of the disc-shaped heating tube formed by the far-infrared heating tube 120, and the distance between it and the heating plate 110 is less than 5 mm, preferably 1 mm to 3 mm.

[0072] Thermocouples are commonly used temperature-sensing elements in temperature measuring instruments. They directly measure temperature and convert the temperature signal into a thermoelectric potential signal. As a passive sensor, a thermocouple does not require an external power supply during measurement, making it very convenient to use. Therefore, it is often used to measure the temperature of gases or liquids in furnaces and pipes, as well as the surface temperature of solids.

[0073] The control device 300 is used to collect the current temperature collected by the temperature acquisition device 200, and to control the heating of the far-infrared heating tube 120 according to the current temperature. Specifically, after receiving the electrical signal sent by the temperature acquisition device 200, the control device 300 determines the current temperature collected by the temperature acquisition device 200 according to the electrical signal, and then controls the heating of the far-infrared heating tube 120 according to the current temperature.

[0074] In an optional embodiment, the control device 300 includes a controller CPU (central processing unit) 310 and a heating driver 320 in the heating device 10. The controller 310 receives an electrical signal from the temperature acquisition device 200 and determines the current temperature acquired by the temperature acquisition device 200 based on the signal. Then, it controls the output signal of the heating driver 320 based on the current temperature, and this output signal controls the heating power of the far-infrared heating tube 120.

[0075] Before receiving the electrical signal, a power-on command is received first. Upon receiving the power-on command, the display screen shows various functions, such as stir-frying, soup making, and hot pot. When an execution command for the first function is received, the corresponding operating mode for that function is executed. For example, when an execution command for the stir-frying function is received, the corresponding operating mode for that function is to control the far-infrared heating element 120 to operate at full power, ranging from 1900 watts (W). It should be noted that regardless of the selected function, the far-infrared heating element 120 always operates at full power.

[0076] S220, based on the adjustment relationship between temperature and heating mode, determine the adjusted heating mode corresponding to the current temperature. In the adjustment relationship between temperature and heating mode, the higher the temperature, the shorter the heating duration and / or the lower the heating power in the corresponding heating mode.

[0077] The adjustment relationship between temperature and heating mode is preset and stored in the control device 300. In order to effectively control the heating plate 110 to cool down in time when operating at high temperature, in the adjustment relationship between temperature and heating mode, the higher the temperature, the shorter the heating duration and / or the lower the heating power in the corresponding heating mode. Alternatively, in the adjustment relationship between temperature and heating mode, other factors that affect heating in the corresponding heating mode when the temperature is higher can also be set. This embodiment does not limit this, but the principle that must be followed is to effectively control the heating plate 110 to cool down in time when operating at high temperature.

[0078] In an optional embodiment, the adjustment relationship between temperature and heating mode is configured such that different heating modes correspond to different temperature ranges. For example, a first temperature, a second temperature, and a third temperature are set, wherein the first temperature is lower than the second temperature, and the second temperature is lower than the third temperature. The first temperature is, for example, 500°C, the second temperature is, for example, 600°C, and the third temperature is, for example, 700°C.

[0079] When the current temperature is determined to be greater than or equal to a first temperature, based on the adjustment relationship between temperature and heating mode, the adjusted heating mode is determined to reduce the heating power of the far-infrared heating tube 120 to a preset power range. For example, when the current temperature is greater than or equal to 500℃, the adjusted heating mode is determined to reduce the heating power of the far-infrared heating tube 120 to between 1400W and 1600W.

[0080] When the current temperature is determined to be greater than or equal to the second temperature, based on the adjustment relationship between temperature and heating mode, the adjusted heating mode is determined to stop heating at fixed intervals. For example, if the current temperature is greater than or equal to 600℃, the adjusted heating mode is determined to be intermittent heating, that is, stopping heating at fixed intervals (such as every 30 seconds).

[0081] When the current temperature is determined to be greater than or equal to the third temperature, the adjusted heating mode is set to stop heating based on the adjustment relationship between temperature and heating mode. For example, if the current temperature is greater than or equal to 700℃, the adjusted heating mode is set to stop heating.

[0082] The heating device 100 described above also includes a reflector 130, which is disposed on the side of the far-infrared heating tube 120 near the mounting base 400, that is, the reflector 130 is installed between the far-infrared heating tube 120 and the mounting base 400. The heating device 100 also includes other components, which will not be listed here. The mounting base 400 may include a bottom cover and side covers, which form a recessed base. The reflector 130 is mounted on the bottom cover, and the far-infrared heating tube 120 is mounted above the reflector 130 away from the bottom cover.

[0083] When the current temperature is greater than or equal to the second temperature and less than the third temperature, this adjusted heating mode is to protect the heating plate 110 (ceramic plate) from overheating. When the current temperature is greater than the third temperature, this adjusted heating mode is to protect the emitting plate from overheating.

[0084] S230, adjust the heating mode of the far-infrared heating tube in the heating device according to the adjusted heating mode.

[0085] The heating mode of the far-infrared heating tube 120 in the heating device 100 is adjusted according to the adjusted heating mode, that is, the heating mode of the far-infrared heating tube 120 is adjusted to the adjusted heating mode.

[0086] As described in the example above, when the adjusted heating mode reduces the heating power of the far-infrared heating tube 120 to a preset power range, a first signal is output. This first signal is used to reduce the heating power of the far-infrared heating tube 120 to the preset power range. When the adjusted heating mode stops heating at fixed intervals, a second signal is output. This second signal is used to control the far-infrared heating tube 120 to stop heating at fixed intervals when it is in the heating state. When the adjusted heating mode stops heating, a third signal is output. This third signal is used to control the far-infrared heating tube 120 to stop working.

[0087] The first, second, and third signals can be understood as voltage signals, all used to control the heating of the far-infrared heating tube 120. The first signal can be a voltage reduction signal, used to reduce the heating power of the far-infrared heating tube 120. The second signal can be an intermittent voltage interruption signal, used to control the far-infrared heating tube 120 to heat intermittently when it is in a heating state. The third signal can be a voltage interruption signal, which is directly used to cut off the operation of the far-infrared heating tube 120.

[0088] As described above, the control device 300 includes a controller 310 and a heating driver 320. The first signal, the second signal, and the third signal are used to control the operation of the far-infrared heating tube 120 by controlling the operation of the heating driver 320.

[0089] In an optional embodiment, after outputting the third signal, the cooling effect needs to be checked again. If the cooling effect does not meet expectations, it may be due to a malfunction in the heating device 10 itself or an unsatisfactory cooling effect caused by the surrounding environment. In this case, it is necessary to control the heating device 10 to stop working or directly alarm to avoid continuous high temperature leading to equipment damage or personal injury.

[0090] Specifically, after outputting the third signal, and after a fixed duration, when it is determined that the difference between the current temperature collected by the temperature acquisition device 200 and the third temperature is less than or equal to a preset difference, a fourth signal is output. This fourth signal is used to control the entire heating device 10 to stop working. The fixed duration and the preset difference can be set according to actual needs, and are not limited in this embodiment.

[0091] To further understand the control method of the heating device provided in this embodiment, please refer to [link / reference]. Figure 3 This is another flowchart illustrating the control method for this heating device. (For example...) Figure 3 As shown, after the heating device 10 is powered on (i.e., after receiving the power-on command as described above), it receives the selected function (such as stir-frying, soup making, hot pot, etc.) and begins full-power heating. When the current temperature collected by the temperature acquisition device 200 is greater than or equal to 500℃ (the first temperature), the heating power is reduced, that is, the heating power of the far-infrared heating tube 120 is reduced to a preset power range (such as 1400W to 1600W). When the current temperature collected by the temperature acquisition device 200 is greater than or equal to 600℃ (the first temperature), intermittent heating occurs, that is, heating stops at fixed intervals. When the current temperature collected by the temperature acquisition device 200 is greater than or equal to 700℃ (the first temperature), heating stops. After a period of time following the cessation of heating, the device can be turned off directly.

[0092] When the current temperature collected by the temperature acquisition device 200 is less than 500℃ (the first temperature), it still maintains full power heating.

[0093] Optionally, when the current temperature collected by the temperature acquisition device 200 is greater than or equal to 700℃ (first temperature), the heating power of the far-infrared heating tube 120 can also be reduced to a preset power range (such as 1400W to 1600W).

[0094] In summary, this embodiment provides a control method for a heating device, comprising: upon receiving an electrical signal from a temperature acquisition device, determining the current temperature acquired by the temperature acquisition device based on the electrical signal; determining an adjusted heating mode corresponding to the current temperature based on the adjustment relationship between temperature and heating mode, wherein, in the adjustment relationship between temperature and heating mode, the higher the temperature, the shorter the heating duration and / or the lower the heating power in the corresponding heating mode; and adjusting the heating mode of the far-infrared heating tube in the heating device according to the adjusted heating mode.

[0095] The control method of this heating device can be understood as a control device 300 applied to the heating device 10, which communicates with the temperature acquisition device 200 in the heating device 10. The temperature acquisition device 200 is used to acquire the air temperature around the far-infrared heating tube 120 in the heating device 10 (such as the far-infrared furnace described above). The control device 300 confirms the corresponding adjusted heating mode based on the current temperature acquired by the temperature acquisition device 200, and adjusts the heating mode of the far-infrared heating tube 120 in the heating device 100 according to the adjusted heating mode. It should be noted that in the adjustment relationship between temperature and heating mode, the higher the temperature, the shorter the heating duration and / or the lower the heating power in the corresponding heating mode. That is, when the far-infrared heating tube 120 is running at high temperature, the temperature is controlled in a timely manner by reducing the heating power and heating duration, etc., to prevent the far-infrared heating tube 120 from running at a high temperature continuously, which could cause injury to the user or damage to the equipment itself, thereby improving the safety factor of the heating device 10 (such as the far-infrared furnace) during use.

[0096] Please see Figure 4 An embodiment of this application also provides a heating device 10, which includes a heating element 100, a temperature acquisition device 200, a control device 300, and a mounting base 400, wherein the temperature acquisition device 200 is signal-connected to the control device 300.

[0097] The heating device 100 includes a heating plate 110 and a far-infrared heating tube 120. The far-infrared heating tube 120 is disposed on the mounting base 400, and the heating plate 110 is laid on the side of the far-infrared heating tube 120 away from the mounting base 400. The far-infrared heating tube 120 can be a disc-shaped heating tube, such as... Figure 4 The disc-shaped heating element is shown. The heating plate 110 is laid on the side of the disc-shaped heating element away from the mounting base 400.

[0098] The heating device 100 also includes a reflector 130, which is laid on the side of the far-infrared heating tube 120 near the mounting base 400. That is, the reflector 130 is installed between the far-infrared heating tube 120 and the mounting base 400. The heating device 100 also includes other components, which will not be listed here.

[0099] The mounting base 400 may include a bottom cover and a side cover, which together form a recessed base. A reflector 130 is mounted on the bottom cover, and a far-infrared heating tube 120 is mounted on the reflector 130 above the bottom cover.

[0100] The temperature acquisition device 200 is disposed between the heating plate 110 and the far-infrared heating tube 120. The temperature acquisition device 200 is, for example, a thermocouple, which is disposed at the center of the disc-shaped heating tube and the distance between it and the heating plate 110 is less than 5 mm, preferably 1 mm to 3 mm.

[0101] The temperature acquisition device 200 is used to acquire temperature signals and convert them into electrical signals, which are then sent to the control device 300. The control device 300 is used to execute the control method for the heating device provided in any of the above embodiments, as detailed in the above description, which will not be repeated here.

[0102] The control device 300 includes a controller 310 and a heating driver 320. One end of the heating driver 320 is connected to the power board 20, and the other end is connected to the far-infrared heating tube 120. When operating, the heating driver 320 drives the far-infrared heating tube 120 to generate heat. The controller 310 controls the output signal of the heating driver 320, which in turn controls the heating power of the far-infrared heating tube 120. As described in the control method of the heating device provided in the above embodiment, when the far-infrared heating tube 120 is operating at high temperature, it needs to be cooled down promptly. At this time, the controller 310 can reduce the driving voltage output by the heating driver 320 to control the heating power of the far-infrared heating tube 120 by controlling the driving voltage.

[0103] Please also see Figure 4 In one embodiment of this application, the heating device 10 further includes an isolation plate 500, which is disposed on the outer periphery of the disc-shaped heating tube. A thermal fuse 510 is provided on the isolation plate 500. When the thermal fuse 510 melts, the far-infrared heating tube 120 stops heating. The melting point of the thermal fuse 510 can be selected according to actual needs. When the thermal fuse 510 melts, it can be understood that the temperature of the far-infrared heating tube 120 has exceeded the maximum limit temperature. At this time, the power board directly cuts off the power supply, and the entire transmitting device stops working to prevent high-temperature burns.

[0104] In summary, the heating device 10 provided in the embodiments of this application includes a heating element 100, a temperature acquisition device 200, a control device 300, and a mounting base 400. The heating element 100 includes a heating plate 110 and a far-infrared heating tube 120. The far-infrared heating tube 120 is disposed on the mounting base 400, and the heating plate 110 is laid on the side of the far-infrared heating tube 120 away from the mounting base 400. The heating plate 110 can be understood as a baking tray, which will come into direct contact with the user. The temperature acquisition device 200 is disposed between the heating plate 110 and the far-infrared heating tube 120, and is used to acquire temperature signals and convert these temperature signals into electrical signals. That is, the temperature acquisition device 200 is used to acquire the temperature between the heating plate 110 and the far-infrared heating tube 120. The control device 300 is used to first determine the current temperature based on the electrical signal, and then determine the adjusted heating mode of the far-infrared heating tube 120 based on the adjustment relationship between the temperature and the heating mode. It should be noted that in the relationship between temperature and heating mode, the higher the temperature, the shorter the heating duration and / or the lower the heating power in the corresponding heating mode.

[0105] In other words, when the current temperature (the temperature between the heating plate 110 and the far-infrared heating tube 120) collected by the temperature acquisition device 200 is higher, the control device 300 will control the far-infrared heating tube 120 to reduce its heating power and / or reduce its heating time, thereby preventing the heating plate 110 from overheating. Therefore, the heating device provided by the embodiments of this application has a high safety factor, solving the problem of how to improve the safety factor of heating devices (such as far-infrared furnaces) during use.
