The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0023] Please refer to Figures 1 to 3 , Figure 1 It is a schematic flowchart of an embodiment of the power adjustment method of the household appliance of the present application; Figure 2 It is a schematic sub-flowchart of an embodiment of the power adjustment method of the household appliance of the present application; Figure 3 It is another schematic sub-flowchart of an embodiment of the power adjustment method of the household appliance of the present application.

[0024] An embodiment of the present application discloses a power adjustment method for a household appliance. The power adjustment method includes the following steps:

[0025] S11: Detect the current voltage and determine the desired power.

[0026] In the embodiment of the present application, the power adjustment method of the household appliance is equipped with a voltage detection circuit to detect the current voltage currently accessed by the household appliance and determine the desired power required by the user.

[0027] Among them, detecting the current voltage can be the current voltage detected in real time; or detecting the current voltage at regular intervals preset time; or detecting the current voltage each time the household appliance is enabled. The desired power refers to the desired power set by the user or the optimal desired power calculated by the system.

[0028] In actual use, the desired power can be a specific power value, or a power level, and the power level can be preset according to the specific power adjustment accuracy.

[0029] In some embodiments, the current voltage can be detected in real time, and after determining the desired power, it can be used to determine a power adjustment scheme according to the current voltage subsequently, so that the power of the household appliance can be adjusted according to the fluctuations of the real-time voltage, ensuring that the power of the household appliance is always within the preset power. In still other embodiments, the current voltage can also be detected at preset intervals, and used to determine a power adjustment scheme according to the current voltage regularly, so that the power of the household appliance can be adjusted regularly according to the voltage fluctuations. In still other embodiments, the current voltage can also be detected when the household appliance starts to be used, and used to determine the power adjustment scheme for this use of the household appliance according to the current voltage.

[0030] S12: Determine a power adjustment scheme according to the rated voltage and rated full power of the household appliance, as well as the current voltage and desired power.

[0031] The rated voltage and rated full power of the household appliance are usually set at the factory. The rated voltage is usually the standard voltage of the country or region where it is used, and the rated full power refers to the maximum heating power under the rated voltage.

[0032] Therefore, the rated voltage and rated full power of the household appliance are known. According to the rated voltage and rated full power of the household appliance, the current voltage detected in the previous step S11, and the desired power set by the user or calculated by the system, the power adjustment scheme can be determined.

[0033] Compared with the prior art where the household appliance does not have a voltage detection circuit and uses the same power at high and low voltages, the power adjustment method of the household appliance in the embodiment of the present application automatically adjusts the usage power of the household appliance at different high and low voltages. When the household appliance is a cooking device with a heating function, the method in the embodiment of the present application can avoid the situation of violent boiling under high voltage and uncooked food materials under low voltage, ensuring that the household appliance always maintains the desired power at different voltages and always maintains excellent cooking effects.

[0034] When the household appliance is a heating device, a hair dryer or other devices, at different voltages, the method in the embodiment of the present application can determine a power adjustment scheme, so that the household appliance maintains the preset desired power to obtain a stable usage effect.

[0035] The method of the present application can calculate and determine the power adjustment scheme by detecting the current voltage, and then according to the rated voltage and rated full power of the household appliance, as well as the current voltage and desired power. The method is simple and convenient, and does not require too much performance debugging work.

[0036] In some embodiments, determining a power adjustment scheme according to the rated voltage and rated power of the household appliance, as well as the current voltage and desired power, includes the following steps:

[0037] S121: Determine the current full power according to the rated voltage, the rated full power, and the current voltage.

[0038] Since the rated voltage U and the rated full power P of a household appliance are fixed, after detecting the current voltage u, the current full power p of the household appliance under the current voltage u can be calculated. Specifically, determining the current full power p according to the rated voltage U, the rated full power P, and the current voltage u includes: calculating the ratio of the square of the current voltage u to the square of the rated voltage U, and then multiplying it by the rated full power P, so as to obtain the current full power p. The calculation formula is as follows:

[0039] p = u * u * P / (U * U)

[0040] The principle is that since it is the same household appliance, its circuit remains unchanged. The rated full power P = (U * U) / R, and when the voltage value changes to the current voltage u, the current full power p = (u * u) / R. Through conversion, the current full power p = u * u * P / (U * U) is obtained.

[0041] In other embodiments, the current full power can also be calculated by other methods.

[0042] S122: Determine the power adjustment scheme according to the current full power and the desired power.

[0043] In some embodiments, determining the power adjustment scheme according to the current full power and the desired power includes:

[0044] S1221: Calculate the number of power adjustment cycles according to the rated full power and the preset power adjustment accuracy.

[0045] The preset power adjustment accuracy is the minimum power value that can be adjusted each time the power is adjusted. According to the rated full power and the preset power adjustment accuracy, the number of power adjustment cycles can be calculated. Specifically, calculating the number of power adjustment cycles according to the rated full power and the preset power adjustment accuracy includes: dividing the rated full power P by the preset power adjustment accuracy z to obtain the number of power adjustment cycles T.

[0046] It should be noted that in this embodiment, the method of realizing power adjustment by the thyristor wave-loss scheme is adopted. The preset power adjustment accuracy needs to be z watts. Dividing the rated full power P by the preset power adjustment accuracy z to obtain the wave-loss power adjustment cycle number T, T = P / z. For example, if the rated full power P of the rated voltage U is 800W and the preset power adjustment accuracy z is set to 50W, then the power adjustment cycle number T = 800 / 50 = 16; if the rated full power P of the rated voltage U is 800W and the preset power adjustment accuracy z is set to 20W, then the power adjustment cycle number T = 800 / 20 = 40.

[0047] It can be understood that the smaller the value of the preset power adjustment accuracy z, the more adjustable power levels, the higher the adjustment accuracy, and the larger the number of power adjustment cycles. The number of power adjustment cycles can also be understood as the number of adjustment levels of the rated full power.

[0048] S1222: Calculate the number of on-cycles according to the current full power, the number of power adjustment cycles, and the desired power.

[0049] Since the current full power, the number of power adjustment cycles, and the desired power are known, the number of on-cycles required to adjust to the desired power at the current voltage can be calculated. The number of on-cycles refers to the number of sine waves that need to be turned on within a cycle. Specifically, calculating the number of on-cycles m according to the current full power P, the number of power adjustment cycles T, and the desired power W includes: calculating the ratio of the desired power W to the current full power p, and then multiplying it by the number of power adjustment cycles T to obtain the number of on-cycles m, m=(W*T) / p. At the current voltage u, if it is necessary to adjust to the desired power W, that is, it is necessary to determine the number of on-cycles m according to the ratio of the desired power W to the current full power p and the number of power adjustment cycles T. By substituting the calculation formula of the current full power p in step S121, the number of on-cycles m can be obtained. The formula is as follows:

[0050] m = T*U*U*W / (u*u*P)

[0051] Among them, the calculated number of on-cycles m may not be an integer, and the integer number of on-cycles m can be obtained by rounding, that is, the number of sine waves within a cycle. Thus, the average output power of the load is controlled by the number of sine waves passing through the load.

[0052] S1223: Determine the power adjustment scheme corresponding to the number of on-cycles.

[0053] In some embodiments, determining the power adjustment scheme corresponding to the number of on-cycles includes: calling a preset wave-drop combination scheme to obtain the power adjustment scheme of the desired power at the current voltage; among them, the preset wave-drop combination scheme is obtained through pre-testing and meets the electromagnetic compatibility requirements.

[0054] Since the number of on-cycles corresponding to the desired power at the current voltage is determined, that is, the number of sine waves within a cycle, the corresponding power adjustment scheme can be determined according to the number of on-cycles. Since different circuit environments have different achievable wave-drop combination schemes, there are various methods to achieve the corresponding number of sine waves of the load within a cycle. For example, the wave-drop combination scheme can be achieved by leaving one sine wave empty and then connecting another sine wave, or by leaving two sine waves empty and then connecting two sine waves, etc. as long as the electromagnetic compatibility requirements are met. Therefore, a preset wave-drop combination scheme that meets the electromagnetic compatibility requirements is needed to implement the power adjustment scheme.

[0055] After determining the number of on - cycles, that is, the number of sine waves within a cycle, query and call a preset wave - loss combination scheme that meets the electromagnetic compatibility requirements to obtain a power adjustment scheme corresponding to the number of on - cycles. Then, at the current voltage, the desired power can be obtained.

[0056] The method of the embodiment of the present application sets several desired power levels that can be adjusted by setting a preset power adjustment accuracy. Subsequently, it detects the current voltage and the desired power to be adjusted, calculates the number of on - cycles, that is, the number of sine waves within a cycle. Finally, by calling a preset wave - loss combination scheme that meets the electromagnetic compatibility requirements, a power adjustment scheme for the number of on - cycles is obtained, and the desired power is ultimately obtained. The power adjustment method of the household appliance of the present application has simple operations. Using this method, the power deviation corresponding to different voltages can be controlled within the required accuracy range, realizing the stability of the performance of household appliances.

[0057] The power adjustment method of the household appliance of the present application can be used in health - care kettle products and can also be applied to other household appliance products that use thyristors for heating control, such as rice cookers, wall - breakers, etc. When the power adjustment method of the household appliance of the present application realizes thyristor heating, the power is basically the same under different voltage conditions for power adjustment heating.

[0058] Please refer to Figure 4 , Figure 4 which is a schematic framework diagram of an embodiment of the household appliance of the present application.

[0059] Another embodiment of the present application includes a household appliance 20. The household appliance 20 includes a heating device 21 and a control device 22. The control device 22 can control the heating device 21 to implement the power adjustment method in any of the above - mentioned embodiments. Specifically, the control device 22 detects the current voltage and determines the desired power; determines a power adjustment scheme according to the rated voltage and rated full - power of the household appliance, as well as the current voltage and the desired power, and controls the heating device 21 to process according to the power adjustment scheme.

[0060] Further, the control device 22 determines the current full power according to the rated voltage, the rated full power, and the current voltage. And the control device 22 determines a power adjustment scheme according to the current full power and the desired power. Specifically, the control device 22 calculates the number of power adjustment cycles according to the rated full power and the preset power adjustment accuracy; calculates the number of on cycles according to the current full power, the number of power adjustment cycles, and the desired power; and determines a power adjustment scheme corresponding to the number of on cycles. The control device 22 of the household appliance 20 in this application sets several desired power levels that can be adjusted by setting a preset power adjustment accuracy, then detects the current voltage and the desired power to be adjusted, calculates the number of on cycles, that is, the number of sine waves in a cycle, and finally obtains a power adjustment scheme for the number of on cycles by calling a preset wave-drop combination scheme that meets the electromagnetic compatibility requirements, and finally obtains the desired power. The power adjustment method of the household appliance 20 in this application has simple operations, can control the power deviation corresponding to different voltages within the required accuracy range, and realizes the stability of the performance of the household appliance 20.

[0061] The household appliance 20 in this application can be products such as a health care kettle, a rice cooker, a wall breaker, etc. The heating device 21 in this application includes a thyristor heating device. When the household appliance 20 in this application realizes thyristor heating, the power is basically the same under different voltage conditions during power adjustment heating.
