Description

Technical Field

[0001] This invention relates to the technical field of kitchen appliances, and more specifically to a control method for a heating appliance and a heating appliance. Background Technology

[0002] Currently, sugar-reducing rice on the market mainly reduces the sugar content by installing a steaming rack inside the heating appliance to rinse the rice or separating the rice water. While this method can dissolve the starch and sugar in the rice into the water, it has limitations, and the sugar-reducing effect cannot fully meet users' needs.

[0003] To further enhance the blood sugar-lowering effect, the applicant discovered through research that refrigerating cooked rice can promote the production of resistant starch, thereby achieving deep blood sugar reduction. However, refrigerated rice requires reheating before consumption, which reduces the resistant starch content. Therefore, heating appliances need to be equipped with special heating methods to both bring the food to a palatable temperature and maximize the resistant starch content.

[0004] Currently, most rice heating appliances cannot determine whether a user's heating requirement is for low-sugar rice with high resistant starch content, nor do they have a special heating curve for low-sugar rice.

[0005] Therefore, there is a need to provide a control method and a heating appliance for heating appliances to at least partially solve the above-mentioned problems. Summary of the Invention

[0006] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0007] According to a first aspect of the present invention, a control method for a heating appliance is provided, the heating appliance comprising a receiving cavity, a heating module, and a temperature detection module, the temperature detection module being used to detect the temperature of the receiving cavity, the control method comprising: Obtain a heating command and obtain the initial temperature of the receiving cavity; If the initial temperature is less than or equal to the first predetermined temperature value T1, the heating module is controlled to heat the cavity in a first heating mode; otherwise, the heating module is controlled to heat the cavity in a second heating mode.

[0008] According to the control method of the present invention, it can be used in heating appliances. When the heating appliance receives a heating command, it can obtain the temperature of the rice in the cavity. When the temperature is lower than the set temperature, it is determined that the rice is refrigerated low-sugar rice. Accordingly, the first heating mode of low-sugar rice is called to heat the rice, so that the food reaches a more palatable temperature and maximizes the content of resistant starch. When the temperature is higher than the set temperature, it is determined that the rice is ordinary rice, and the second heating mode of ordinary rice is called to heat the rice, so as to meet the needs of different users and improve the user experience.

[0009] Optionally, heating the receiving cavity in a first heating mode includes: The cavity is heated by a first predetermined power P1, wherein the first predetermined power P1 is half of the rated power P 额定 Up to three-quarters of the rated power P 额定 Within a selected range, the heating module is controlled to heat the temperature of the accommodating cavity to a second predetermined temperature value T2 with a first predetermined power P1, and then heating is stopped.

[0010] With the above settings, the first heating mode is suitable for refrigerated low-sugar rice. In the first heating mode, the rice is heated with a lower power, which can bring the food to a more palatable temperature, retain the resistant starch content to the maximum extent, and prevent the rice from gelatinizing due to excessively high local temperature.

[0011] Optionally, the second predetermined temperature value T2 is selected within the range of 40℃≤T2≤90℃.

[0012] By using the above settings, the food can be brought to a palatable temperature while retaining the maximum amount of resistant starch.

[0013] Optionally, the second predetermined temperature value T2 is selected within the range of 50℃≤T2≤80℃.

[0014] By using the above settings, the food can be brought to a palatable temperature while retaining the maximum amount of resistant starch.

[0015] Optionally, after the temperature of the receiving cavity is heated to the second predetermined temperature value T2, the duration for which heating is stopped reaches a heating stop duration t. 停止 Then, the heating module is controlled to heat the receiving cavity at a third predetermined power P3, wherein the third predetermined power P3 is less than or equal to one-quarter of the rated power P. 额定The range is selected, and the temperature of the receiving cavity is maintained between the third predetermined temperature value T3 and the fourth predetermined temperature value T4. When the duration of the temperature of the receiving cavity between the third predetermined temperature value T3 and the fourth predetermined temperature value T4 reaches the first predetermined duration t1, the heating module is controlled to stop heating, and the heating process of the first heating mode ends.

[0016] Using the above settings, the duration of heating cessation reaches the heating cessation duration t. 停止 This method avoids uneven heating of rice, ensuring a more uniform overall temperature. Furthermore, by using lower power for heating, the rice temperature is maintained within a suitable range, preventing the rice from gelatinizing due to excessively high local temperatures.

[0017] Optionally, the relationship between the third predetermined temperature value T3 and the fourth predetermined temperature value T4 is: T4 = T3 + 2℃.

[0018] By using the above settings, the temperature of the rice can be maintained within a range of 2℃, thus ensuring even heating, preventing the rice from gelatinizing, and improving the cooking effect.

[0019] Optionally, the third predetermined temperature value T3 is selected within the range of 40℃≤T3≤90℃.

[0020] By using the above settings, the rice temperature can be maintained within a suitable range, avoiding the problem of rice gelatinization caused by excessively high local temperatures.

[0021] Optionally, the third predetermined temperature value T3 is selected within the range of 50℃≤T3≤80℃.

[0022] By using the above settings, the rice temperature can be maintained within a suitable range, avoiding the problem of rice gelatinization caused by excessively high local temperatures.

[0023] Optionally, the first predetermined temperature value T1 is selected within the range of 5℃≤T1≤10℃.

[0024] By using the above settings and temperature range, it is possible to effectively determine whether the rice is refrigerated low-sugar rice or regular rice, thus improving the accuracy of the heating appliance's judgment.

[0025] Optionally, heating the receiving cavity in a second heating mode includes: The cavity is heated by a second predetermined power P2, wherein the second predetermined power P2 is greater than three-quarters of the rated power P. 额定Within the selected range, the heating module is controlled to heat the temperature of the receiving cavity to a fifth predetermined temperature value T5, or after the heating duration of the receiving cavity reaches a second predetermined duration t2, the heating module is controlled to stop heating, and the heating process of the second heating mode ends.

[0026] With the above settings, the second heating mode is suitable for ordinary rice placed at room temperature. Therefore, in the second heating mode, it can be heated quickly with a larger power, so that the ordinary rice can be fully heated.

[0027] Optionally, the fifth predetermined temperature value T5 is selected within the range of 95℃≤T5≤100℃, and the second predetermined duration t2 is selected within the range of 25≤t2≤35 minutes.

[0028] By using the above settings, the rice can be heated thoroughly, ensuring the quality of the cooking.

[0029] According to a second aspect of the present invention, a heating appliance is provided, the heating appliance including a receiving cavity, a heating module and a temperature detection module, the temperature detection module being used to detect the temperature of the receiving cavity, wherein the heating appliance further includes a control module, the control module being capable of controlling the heating appliance to perform the steps of the control method according to any one of the first aspects of the present invention.

[0030] According to the heating appliance of the present invention, when the heating appliance receives a heating command, it can obtain the temperature of the rice in the receiving cavity. When the temperature is lower than the set temperature, it is determined that the rice is refrigerated low-sugar rice. Accordingly, the first heating mode of low-sugar rice is called to heat the rice, so that the food reaches a more palatable temperature and maximizes the content of resistant starch. When the temperature is higher than the set temperature, it is determined that the rice is ordinary rice, and the second heating mode of ordinary rice is called to heat the rice, thereby meeting the needs of different users and improving the user experience.

[0031] Optionally, the heating appliance further includes an inner liner and a lower inner box disposed within the inner liner, the inner liner containing a water bath medium to surround the lower inner box, the receiving cavity including at least the space of the lower inner box, and the heating module for heating the inner liner.

[0032] By using the above-described configuration, the heating appliance can heat rice in a water bath, thereby improving the cooking quality of the rice.

[0033] Optionally, the heating appliance is an electric lunchbox.

[0034] The above setup allows the heating appliance to be used independently and is easy to carry. Attached Figure Description

[0038] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the invention.

[0039] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0040] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, the same reference numerals are used to denote the same elements for clarity, and therefore their description will be omitted.

[0041] This invention provides a control method and a heating appliance that can perform low-sugar processing on rice using a refrigeration device. The control method and heating appliance according to the invention will be described in detail below with reference to the accompanying drawings through a specific embodiment.

[0042] According to a preferred embodiment of the present invention, a heating appliance is provided that can be placed in the refrigerator compartment of a refrigeration device for refrigeration. The heating appliance may be an electric lunchbox, and the refrigeration device may be a refrigerator, freezer, or other device capable of refrigeration.

[0043] Furthermore, the heating appliance has a built-in power supply, which can power the control device, temperature detection device, timing device, and prompting device installed inside the heating appliance without being connected to an external power source. The various components of the heating appliance in this embodiment will be further described below with reference to the accompanying drawings.

[0044] like Figures 1 to 3As shown, the heating appliance 100 mainly includes a bottom shell 110 and a top cover 121. The bottom shell 110 of the heating appliance 100 houses an inner pot 111, a heating module 140, and a built-in power supply 113. The heating module 140 is capable of heating the inner pot 111. Furthermore, the inner pot 111 has a first receiving cavity 112, which can hold a water bath medium (e.g., water). The heating appliance 100 also has a lower inner box 114 that can be placed in the first receiving cavity 112, and food can be placed in the lower inner box 114. In this embodiment, after water and the lower inner box 114 are placed in the first receiving cavity 112, the heating module 140 can heat the inner pot 111, thereby heating the rice in the lower inner box 114 in a water bath manner.

[0045] Multiple support seats 115 can also be provided at the bottom of the first receiving cavity 112 in the inner liner 111. When the lower inner box 114 is placed in the first receiving cavity 112, the support seats 115 can support the lower inner box 114 to prevent the lower inner box 114 from directly contacting the inner liner 111 and to protect the lower inner box 114.

[0046] Furthermore, the built-in power supply 113 is preferably a battery, which can be detachably installed in the bottom housing 110.

[0047] like Figure 3 As shown, the heating appliance 100 also includes a support frame 130, which can be detachably placed on top of the bottom shell 110. After the inner box 114 is placed in the first receiving cavity 112 of the inner liner 111, placing the support frame 130 on the bottom shell 110 can protect the food in the inner box 114 and also keep it warm.

[0048] Preferably, in order to accommodate more food, the heating appliance 100 in this embodiment further includes an upper inner box 123, and the upper cover 121 forms a second receiving cavity 122 that can accommodate the upper inner box 123. The support frame 130 is provided with multiple through holes, and when the heating module 140 heats the inner liner 111, the high-temperature steam formed by the water in the first receiving cavity 112 can enter the second receiving cavity 122 of the upper cover 121 through the through holes on the support frame 130.

[0049] Therefore, after the upper cover 121 is installed on the bottom shell 110, the first receiving cavity 112 of the inner liner 111 and the second receiving cavity 122 of the upper cover 121 together form the receiving cavity of the heating appliance 100. The food to be cooked can be placed in the receiving cavity by means of the upper inner box 123 and the lower inner box 114. The heating module 140 heats the inner liner 111, thereby heating the food to be cooked.

[0050] To restrict the movement of the upper inner box 123, the upper surface of the support frame 130 is also provided with an upwardly protruding limiting seat surrounding the upper inner box 123. When the upper inner box 123 is placed on the support frame 130, the limiting seat can prevent the upper inner box 123 from moving, thereby preventing food from spilling out of the upper inner box 123. In addition, the upper cover 121 can also be provided with an inner liner covering the upper inner box 123 to protect the food in the upper inner box 123 and to keep it warm.

[0051] After the inner box 114, support frame 130, and upper inner box 123 are placed sequentially on the bottom shell 110, the upper inner box 123 can be fixedly installed on the bottom shell 110 to prevent the upper cover 121 from falling off the bottom shell 110 during the movement of the heating appliance 100, thus making the heating appliance 100 easy to carry. For example, the upper inner box 123 and the bottom shell 110 can be fixed together by a snap-fit ​​connection.

[0052] Preferably, the control panel of the heating appliance 100 may also be equipped with an indicator light. When the lower inner box 114 is not placed in the heating appliance 100, the indicator light can be fully lit to remind the user to place the lower inner box 114 into the heating appliance 100. The control panel of the heating appliance 100 may be powered by its built-in power supply 113.

[0053] In this embodiment, the sugar content of the rice in the heating appliance 100 can be reduced by refrigeration using the heating appliance 100 and the refrigeration device 200. Specifically, after the cooked rice is placed in the heating appliance 100, if the user needs low-sugar rice, the heating appliance 100 can be placed in the refrigeration device 200, and after refrigeration is complete, the heating appliance 100 can be taken out of the refrigeration device 200 to obtain low-sugar rice.

[0054] It is understood that the heating appliance 100 can be placed in the refrigerator compartment of the refrigeration equipment 200, the temperature of which is preferably set below 5°C, for example, the temperature of the refrigerator compartment can be set below 3°C.

[0055] Refrigerated rice needs to be reheated before consumption, but heating reduces the resistant starch content. Therefore, this embodiment also provides a control method, such as... Figure 5 and Figure 6 As shown, this method aims to achieve both a palatable temperature for the food and maximize the content of resistant starch.

[0056] Specifically, such as Figure 5 As shown, the control method includes: Obtain a heating command and obtain the initial temperature of the receiving cavity; If the initial temperature is less than or equal to the first predetermined temperature value T1, the heating module is controlled to heat the cavity in a first heating mode; otherwise, the heating module is controlled to heat the cavity in a second heating mode.

[0057] In this embodiment, the heating appliance 100 may be equipped with a button that can trigger the heating function, or a touch screen that can be operated. The user can press the button or operate the display screen to enable the heating appliance 100 to obtain a heating command so as to control the heating module 140 to perform heating.

[0058] like Figure 4 As shown, the heating appliance 100 in this embodiment also includes a temperature detection module 160 and a control module 150. The temperature detection module 160 can detect the temperature inside the receiving cavity of the heating appliance 100. For example, the temperature detection module 160 can be located at the top, side, or bottom of the receiving cavity to effectively detect the temperature inside the cavity. It is understood that both the heating module 140 and the temperature detection module 160 are electrically connected to the control module 150. The control module 150 can receive the temperature information detected by the temperature detection module 160 to control the heating module 140 to heat the inner pot, thereby better performing the cooking function. In this embodiment, the built-in power supply 113 is electrically connected to the control module 150 and can provide power to the control module 150.

[0059] Furthermore, after the heating appliance 100 receives a heating command input from the user, it immediately detects the initial temperature inside the receiving cavity using the temperature detection module 160. If the initial temperature inside the receiving cavity is less than or equal to a first predetermined temperature value T1, it indicates that the rice inside the heating appliance 100 has just been refrigerated. In this case, the rice needs to be heated using the first heating mode to bring the food to a palatable temperature while maximizing the content of resistant starch, ensuring the low-sugar effect of the rice, and improving the cooking quality.

[0060] If the initial temperature inside the cavity is greater than the first predetermined temperature value T1, it indicates that the rice in the current heating appliance 100 is ordinary rice at room temperature. In this case, the rice can be heated in the second heating mode.

[0061] Preferably, the rated power P of the heating module 140 is... 额定 The power rating can be selected within the range of 100W to 600W. More preferably, the rated power P of the heating module 140 is... 额定 The value can be selected within the range of 200W to 300W.

[0062] In this embodiment, heating the receiving cavity in a first heating mode includes: The cavity is heated by a first predetermined power P1, where the first predetermined power P1 is half of the rated power P. 额定 Up to three-quarters of the rated power P 额定 The temperature of the cavity is selected within the range, and heating is stopped after the temperature of the cavity is heated to the second predetermined temperature value T2.

[0063] For example, in this embodiment, the rated power P of the heating module 140 额定 If the first predetermined power is 200W, then the first predetermined power P1 = 150W. Of course, in other embodiments, the first predetermined power P1 can also be other values, for example, the first predetermined power can be equal to 100W.

[0064] Preferably, the second predetermined temperature value T2 is selected within the range of 40℃ ≤ T2 ≤ 90℃. More preferably, the second predetermined temperature value T2 is selected within the range of 50℃ ≤ T2 ≤ 80℃. For example, T2 = 50℃.

[0065] With the above settings, the first heating mode is suitable for refrigerated low-sugar rice. In the first heating mode, the power is less than the rated power P. 额定 The rice is heated with a lower power and heated to a second predetermined temperature value T2. This not only brings the food to a more palatable temperature but also maximizes the retention of resistant starch content and prevents the rice from gelatinizing due to excessively high local temperatures.

[0066] In the control method of this embodiment, after the temperature of the receiving cavity is heated to a second predetermined temperature value T2, when the duration of heating cessation reaches the heating cessation duration t... 停止 Afterward, the overall temperature of the rice becomes roughly uniform. At this point, the heating appliance 100 can control the heating module 140 to heat the receiving cavity at a lower third predetermined power P3, where the third predetermined power P3 is less than or equal to one-quarter of the rated power P. 额定 The temperature of the receiving cavity is selected within a range, and is maintained between a third predetermined temperature value T3 and a fourth predetermined temperature value T4. When the temperature of the receiving cavity remains between the third predetermined temperature value T3 and the fourth predetermined temperature value T4 for a duration equal to a first predetermined duration t1, the heating module 140 stops heating, and the heating process of the first heating mode ends. After the heating process of the first heating mode ends, the heating appliance 100 can enter the heat preservation stage.

[0067] Among them, the heating stop time t 停止 It can be 0.5≤t 停止 Selected within the range of ≤8 minutes. More preferably, the heating stop time t 停止 It can be 1≤t 停止 Select within the range of ≤3 minutes. For example, the duration t after heating stops. 停止 =2 minutes.

[0068] In one implementation, after the heating module 140 heats the cavity with a third predetermined power P3 to raise the temperature to a fourth predetermined temperature value T4, the heating is immediately stopped, and the temperature inside the cavity will gradually decrease. When the temperature decreases to the third predetermined temperature value T3, the heating module 140 heats the inner liner again with a third predetermined power P3, causing the temperature inside the cavity to rise again. This cycle is repeated to maintain the temperature inside the cavity between the third predetermined temperature value T3 and the fourth predetermined temperature value T4.

[0069] Preferably, in this embodiment, the relationship between the third predetermined temperature value T3 and the fourth predetermined temperature value T4 is: T4 = T3 + 2℃. Of course, in other embodiments, the difference between the fourth temperature value and the third temperature value can be other values, for example, T4 = T3 + 5℃.

[0070] Furthermore, the third predetermined temperature value T3 ranges from 40 to 90°C. More preferably, the third predetermined temperature value T3 ranges from 50 to 80°C; for example, in this embodiment, T3 = 70°C and T4 = 72°C.

[0071] This further prevents the rice from getting too hot in certain areas, allowing for even heat transfer between different parts of the rice and improving the cooking results.

[0072] Preferably, the first predetermined duration t1 can be selected within the range of 8 minutes ≤ t1 ≤ 15 minutes. For example, t1 = 10 minutes.

[0073] Next, the control method of this embodiment will be described in detail. Heating the receiving cavity in the second heating mode may specifically include: The cavity is heated by a second predetermined power P2, where the second predetermined power P2 is greater than three-quarters of the rated power P. 额定 Within the selected range, the control heating module 140 heats the temperature of the receiving cavity to the fifth predetermined temperature value T5, or after the heating duration of the receiving cavity reaches the second predetermined duration t2, the control heating module 140 stops heating, and the heating process of the second heating mode ends.

[0074] As can be seen from the foregoing, when the initial temperature inside the cavity is higher than the first predetermined temperature value T1, it indicates that the rice in the current heating appliance 100 is ordinary rice at room temperature. At this time, the rice can be heated with a higher heating power in the second heating mode.

[0075] In the second heating mode, the heating module 140 can continuously heat the inner liner 111 with a second predetermined power P2, causing the temperature inside the cavity to rise continuously until the temperature inside the cavity reaches a fifth predetermined temperature value T5, at which point heating stops. Alternatively, the inner liner 111 can be continuously heated with the second predetermined power P2 until the heating duration of the cavity reaches a second predetermined duration t2, at which point heating stops, thus ending the second heating mode.

[0076] For example, in this embodiment, the rated power P of the heating module 140 额定 If the power is 200W, then the second predetermined power P2 = 200W. Of course, in other embodiments, the second predetermined power P2 can be other values. For example, when the rated power of the heating module is 500W, the second predetermined power can be equal to 400W.

[0077] Preferably, the fifth predetermined temperature value T5 is the temperature at the end of heating ordinary rice, which can be equal to 98°C. The second predetermined duration t2 is the maximum heating time for ordinary rice, which can be selected within the range of 25 ≤ t2 ≤ 35 minutes.

[0078] In the above embodiments, the heating appliance 100 is provided with a temperature sensor, which can be used to control each cooking step by detecting the temperature. In order to reduce the manufacturing cost of the heating appliance, in the second embodiment of the present invention, the heating appliance may not be provided with a temperature sensor, and reheating can be achieved only by the duration. The second embodiment will be described in detail below.

[0079] In the second embodiment, the food inside the heating appliance still needs to be reheated after it is removed from the refrigeration equipment.

[0080] In the control method of this embodiment, such as Figure 7 As shown, the heating module 140 can be controlled first to operate at a higher first power P. 01 The inner pot 111 is continuously heated, causing the rice inside the cavity to heat up rapidly; when the first power P is applied... 01 Heating is stopped after the heating duration reaches the first specified time. To prevent the rice at the bottom of the container from burning due to excessive heating, the first time can be selected within the range of 8 to 30 minutes. For example, the first power P... 01 It can be equal to the rated power P of heating module 140 额定 During the period when heating is stopped, the rice inside the cavity can transfer heat to each other, ensuring a consistent overall temperature. Once the heating stoppage lasts for a second duration, the heating module 140 can be controlled to operate at a power lower than the first power P. 01 The second power P 02The inner liner 111 is reheated. Preferably, the first duration can be selected in the range of 8 to 15 minutes, for example, 10 minutes. Furthermore, the second duration can be selected in the range of 0.5 to 8 minutes. Preferably, the second duration can be selected in the range of 1 to 3 minutes, for example, 2 minutes.

[0081] With the second power P 02 During this heating period, the rice in the container can reheat, and heat can be transferred between the different parts of the rice. When the second power P... 02 After the heating duration reaches the third duration, heating is stopped again. For example, the second power P... 02 It can be equal to three-quarters of the rated power P of the heating module 140. 额定 During the second heating pause, the rice inside the container can still transfer heat to each other, ensuring a consistent overall temperature. After the heating pause lasts for a fourth duration, the heating module 140 can be controlled to operate at a power lower than the second power P. 02 The third power P 03 The inner liner 111 is reheated. Preferably, the third duration can be selected in the range of 5 to 15 minutes. More preferably, the third duration can be selected in the range of 5 to 10 minutes, for example, 8 minutes. Furthermore, the fourth duration can be selected in the range of 0.5 to 8 minutes. Preferably, the fourth duration can be selected in the range of 1 to 3 minutes, for example, 2 minutes.

[0082] With the third power P 03 During the heating process, the rice in the container can maintain its temperature. When the third power P... 03 After the heating duration reaches the fifth duration, heating can be stopped again, at which point the heating appliance 100 can cease reheating. The fifth duration can be selected within the range of 3 to 10 minutes. Preferably, the fifth duration can be selected within the range of 3 to 5 minutes, for example, 4 minutes. Exemplarily, the third power P... 03 It can be equal to one-quarter of the rated power P of the heating module 140. 额定 .

[0083] In this embodiment, by repeatedly heating intermittently, with each heating power and heating time gradually decreasing, the cooked rice can gradually heat up, and the overall temperature of the rice tends to be uniform, effectively preventing the rice from gelatinizing and further improving the cooking quality.
