[0002] As household appliances become more and more popular in the market, users have higher and higher requirements for household appliances. For example, in order to save energy consumption of household appliances, users need to put forward power-limited operation requirements for household appliances. However, in order to achieve power-limited operation, household appliances that include compressors and other functional components adopt the method of increasing power only by controlling the compressor, while turning off other functional components. For example, in order to achieve power-limited operation, a multi-functional water heater turns off the electric heater and only turns on the compressor. However, it is difficult to achieve power-limited operation requirements by simply increasing the operating power of the compressor. This method can neither meet the power-limited requirement nor make the compressor run at a higher power, which will reduce the service life of the compressor. Summary of the Invention

[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

[0027] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0028] In one embodiment, Figure 1 A schematic diagram of a power regulation method in one embodiment is shown in FIG. Figure 1 , provides a power regulation method. This embodiment mainly applies this method to a power regulation device. The power regulation device can be installed in any household appliance containing a compressor. The household appliance can specifically be a multi-function water heater, a smart air conditioner, a smart refrigerator, etc. In this embodiment, a multi-function water heater is used as an example. The power regulation method specifically includes the following steps:

[0029] Step S210: upon receiving a power-limited operation request, obtaining the rated power of the compressor in the household appliance.

[0030] Specifically, a power-limited operation request can be initiated by the user or automatically triggered by a home appliance. The user can initiate a power-limited operation request through a remote control, a terminal, a voice command, a gesture command, or a touch operation. A home appliance can automatically trigger a power-limited operation request at a preset time. A power-limited operation request is used to limit the operating power of a home appliance, preventing it from operating at low power for extended periods and failing to provide optimal device functionality. It also prevents it from operating at high power for extended periods, resulting in high energy consumption and shortening its service life.

[0031] When a power-limited operation request is received, it indicates that the home appliance needs to be operated with limited power. At this time, the rated power of the compressor in the home appliance is first obtained to determine whether the compressor can achieve power-limited operation alone. The rated power of the compressor is usually stored in the device information of the home appliance, or the rated power of the compressor can be calculated by the compressor theoretical power calculation formula. The compressor theoretical power calculation formula is W=V*△P*△T, where W is the theoretical power (i.e. rated power), V is the volume ratio, △P is the turbocharger pressure difference, that is, the pressure difference between the inlet and outlet, and △T is the turbocharger temperature difference, that is, the temperature difference between the inlet and outlet.

[0032] When the ambient temperature and the compressor casing temperature are lower than a certain temperature value, the heating device is turned on to heat the compressor, thereby increasing the temperature of the oil inside the compressor; when the temperature rises to a certain temperature value, the power output of the heating device is turned off or reduced; the temperature of the compressor is kept within a certain range, thereby ensuring the normal working characteristics of the oil inside the compressor.

[0033] Step S220: When the rated power of the compressor does not meet the limited power operation request, the first target power corresponding to the compressor and the second target power corresponding to the functional component in the household appliance are determined according to the rated power of the compressor and the operating power of the functional component in the household appliance under different operating modes, wherein the sum of the first target power and the second target power meets the limited power operation request.

[0034] Specifically, when the rated power of the compressor does not meet the limited power operation request, it means that even if the compressor runs at full load, it cannot meet the limited power operation request. In this case, it is necessary to consider the functional components in the household appliance and the compressor to jointly realize limited power operation. Functional components refer to other components in the household appliance that can realize different functions except the compressor. Functional components include at least one of electric heaters, condensers, evaporators, etc. In this embodiment, the functional component is described as an electric heater.

[0035] Functional devices correspond to multiple different operating modes, and functional devices correspond to different fixed operating powers in different operating modes. The rated power of the compressor and the operating power of the functional devices in different operating modes are combined to analyze how to meet the limited power operation request, so as to determine the first target power and the second target power that meet the limited power operation request, and the first target power is less than or equal to the rated power of the compressor.

[0036] Step S230: adjusting the operating power of the compressor according to the first target power.

[0037] Step S240: adjusting the operating power of the functional device according to the second target power.

[0038] Specifically, the operating power of the compressor is adjusted according to the first target power, and the operating power of the functional component is adjusted according to the second target power. The functional component can also meet the user's functional requirements corresponding to the functional component and meet the limited power operation request. That is, the sum of the first target power of the compressor and the second target power of the functional component can meet the limited power operation request. There is no need to rely solely on the compressor to be in a high-power operation state for a long time to meet the limited power operation request, which can extend the service life of the compressor.

[0039] In one embodiment, determining the first target power corresponding to the compressor and the second target power corresponding to the functional component according to the rated power of the compressor and the operating power of the functional component in the household appliance in different operating modes includes:

[0040] determining a candidate power corresponding to the compressor in different operating modes of the functional device based on a difference between a preset limit power in the limited power operation request and the operating power of the functional device in different operating modes;

[0041] Any one of the selected powers having a value less than or equal to the rated power is used as the first target power corresponding to the compressor, and the operating power of the functional component corresponding to the first target power in the corresponding operating mode is used as the second target power.

[0042] Specifically, the power-limited operation request includes a preset power limit, which is less than or equal to the sum of the rated power of the compressor and the maximum operating power of the functional device. The preset power limit can be customized according to the user's requirements for the operating power of home appliances. The operating power of the functional device in different operating modes is fixed and cannot be adjusted, while the operating power of the compressor is adjustable. Therefore, the corresponding selected power of the compressor is determined based on the difference between the preset power limit and the operating power of the functional device in different operating modes. However, the maximum power of the compressor is its rated power, and the operating power of the compressor cannot exceed the rated power. In order to ensure the normal operation of the compressor, any selected power with a value less than or equal to the rated power is selected as the first target power corresponding to the compressor, and the operating power of the functional device calculated to obtain the first target power is used as the second target power, so as to meet the requirement that the sum of the first target power and the second target power is equal to the preset power limit, that is, it meets the power-limited operation request.

[0043] For example, a multi-function water heater requires a 6 kW power limit. The preset power limit is 6 kW, the rated power of the compressor is 3.5 kW, and the power level of the electric heater is 2 + 2 kW. This means the electric heater operates at 2 kW in the first operating mode corresponding to the first power level, and at 4 kW in the second operating mode corresponding to the second power level. Even if the compressor operates at rated power, it cannot meet the power limit requirement. Therefore, the compressor and the electric heater's operating power must be combined to achieve power limit operation. The compressor's target power is determined based on the preset power limit and the electric heater's operating power in different operating modes. The preset power limit is subtracted from the electric heater's operating power in the first operating mode, i.e., 6 - 2 = 4 kW, and 4 kW is used as the compressor's target power. The preset power limit is subtracted from the electric heater's operating power in the second operating mode, i.e., 6 - 4 = 2 kW, and 2 kW is used as the compressor's target power. However, if 4 kW is greater than 3.5 kW, 4 kW cannot be selected as the compressor's first target power. If 2 kW is less than 3.5 kW, 2 kW can be selected as the compressor's first target power.

[0044] Since the fixed gear of the functional device does not require power adjustment, there is no need to adjust the operating power of the functional device based on the selected operating mode during power adjustment. Only the operating power of the compressor power needs to be adjusted, which can reduce the design cost of power adjustment.

[0045] In one embodiment, after determining the selectable power corresponding to the compressor of the functional component in different operating modes based on the difference between the preset limit power in the limited power operation request and the operating power of the functional component in different operating modes, the method further includes:

[0046] When there are multiple candidate powers whose values ​​are less than the rated power and whose values ​​are equal to the rated power, any one of the candidate powers whose value is less than the rated power is used as the first target power corresponding to the compressor, and the operating power of the functional component corresponding to the first target power in the corresponding operating mode is used as the second target power.

[0047] Specifically, when there are multiple candidate powers with values ​​less than the rated power and candidate powers with values ​​equal to the rated power, in order to avoid the compressor running at full load for a long time, resulting in high energy consumption and shortened service life of the compressor, any one of the multiple candidate powers with values ​​less than the rated power is selected as the first target power, and the operating power corresponding to the functional component of the first target power is calculated as the second target power, thereby reducing the energy consumption of the compressor when running at high power, and also reducing the cumulative time that the compressor is running at full load, so as to extend the service life of the compressor.

[0048] For example, the rated power of the compressor is 3 kW, the power level of the electric heater is 2+2 kW, and when the preset power limit is 5 kW, the optional powers of the compressor include 1 kW and 3 kW, then 1 kW is selected as the first target power of the compressor.

[0049] In one embodiment, after determining the selectable power corresponding to the compressor of the functional component in different operating modes based on the difference between the preset limit power in the limited power operation request and the operating power of the functional component in different operating modes, the method further includes:

[0050] Among the multiple candidate powers whose values ​​are less than or equal to the rated power, the candidate power with the smallest value is used as the first target power corresponding to the compressor, and the operating power of the functional component corresponding to the first target power in the corresponding operating mode is used as the second target power.

[0051] Specifically, when there are multiple candidate powers with values ​​less than the rated power, in order to reduce the operating energy consumption of the compressor as much as possible, the candidate power with the smallest value is selected as the first target power, and the operating power corresponding to the functional component of the first target power is calculated as the second target power, thereby further reducing the energy consumption of the compressor when operating at high power, thereby extending the service life of the compressor.

[0052] In one embodiment, adjusting the operating power of the compressor according to the first target power includes:

[0053] Obtaining the current operating power of the compressor;

[0054] When the current operating power is greater than the first target power, reducing the operating power of the compressor to the first target power; or

[0055] When the current operating power is less than the first target power, the operating power of the compressor is increased to the first target power.

[0056] Specifically, when adjusting the operating power of the compressor, first obtain the current operating power of the compressor. The current operating power of the compressor can be calculated with reference to the calculation formula of the actual power of the compressor. The calculation formula of the actual power of the compressor is: actual power of the compressor = cooling capacity / COP, where the cooling capacity is related to the temperature difference and the water flow rate. Cooling capacity = C*M*△t, C is the specific heat capacity, M is the water flow rate, △t is the temperature difference between the inlet and outlet of the chilled water, and COP is a parameter to measure the performance of the unit. It can be understood that in order to consume one unit of power, the unit transfers several units of cooling capacity from the outside to the machine. If the power consumption is 100kw and the cooling capacity is 7kw, the COP is 7 / 100=0.07. The cooling capacity refers to the total amount of heat removed from a confined space, room or area per unit time when the air conditioner is in cooling operation.

[0057] If the compressor is a variable-frequency compressor, it is necessary to determine in real time whether the current operating power is equal to the first target power. If the current operating power is equal to the first target power, no adjustment is required. If the current operating power is greater than the first target power, the compressor frequency must be reduced to reduce its operating power to the first target power. If the current operating power is less than the first target power, the compressor frequency must be increased to increase its operating power to the first target power. The compressor's cooling capacity is proportional to its speed, and the speed of an asynchronous motor is proportional to the frequency of the input current. Therefore, adjusting the frequency can change the compressor's speed and power. By adjusting the frequency, the compressor speed is changed, thereby adjusting the operating power.

[0058] Reference Figure 4That is, determine the target frequency corresponding to the first target power, and obtain the current operating frequency of the compressor. When the target frequency is lower than the current operating frequency, start to reduce the frequency until the target frequency is reached; when the target frequency is higher than the current operating frequency, control the compressor to start increasing the frequency until the target frequency is reached.

[0059] In one embodiment, when adjusting the operating power of the compressor according to the first target power, the method further includes:

[0060] Turning off the functional device;

[0061] Adjusting the operating power of the functional device according to the second target power includes:

[0062] When the operating power of the compressor reaches the first target power, the functional device is started, and the operating power of the functional device is adjusted according to the second target power.

[0063] Specifically, when the operating power of the compressor is adjusted according to the first target power, the functional device is turned off, that is, the compressor and the functional device are controlled separately and in sequence until the operating power of the compressor reaches the first target power, and then the functional device is started and its operating power is adjusted to the second target power. Figure 3 The current operating power of the compressor is 3 kW, and the power level of the electric heater is 2+2 kW. When a power limit operation request with a preset power limit of 6 kW is received, the first target power of the compressor is determined to be 2 kW, and the second target power of the electric heater is determined to be 4 kW. When the operating power of the compressor is reduced, the electric heater is turned off. When the operating power of the compressor reaches 2 kW, the electric heater is started and its operating power is controlled to 4 kW. After the electric heater has been running for a period of time, the preset power limit is reached.

[0064] In one embodiment, when adjusting the operating power of the compressor according to the first target power, the method further includes:

[0065] When the second target power is the operating power of the functional device in a preset operating mode, the operating power of the functional device is adjusted according to the first gear power, wherein the preset operating mode is the operating power in a gear operating mode other than the first gear operating mode, and the first gear power of the functional device in the first gear operating mode is the lowest;

[0066] Adjusting the operating power of the functional device according to the second target power includes:

[0067] When the operating power of the compressor reaches the first target power, the operating power of the functional component is adjusted from the first gear power to the second target power.

[0068] Specifically, when the second target power is not the minimum operating power corresponding to the functional device, the operating power of the functional device can be adjusted according to the minimum operating power corresponding to the functional device when the operating power of the compressor is adjusted according to the first target power. The first gear power is the minimum operating power corresponding to the functional device, that is, the operating power of the functional device is adjusted according to the first gear power. When adjusting the operating power of the compressor, there is no need to turn off the functional device. The power of the two devices is adjusted at the same time, but the power of the compressor is adjusted first. Then, the functional device is only allowed to operate according to the lowest first gear power. After the operating power of the compressor reaches the first target power, the operating power of the functional device is adjusted from the first gear power to the second target power. In this way, the switching energy consumption of the functional device can be saved, and the operating function of the functional device can be adjusted in time when the operating power adjustment of the compressor is completed, which saves the waiting process for the functional device to restart, improves the power adjustment efficiency, and shortens the power adjustment time.

[0069] In a specific embodiment, referring to Figure 2 , when a customer requests limited power operation, that is, when a request for limited power operation is received, the electric heater is no longer directly turned off to adjust the power of the compressor alone, making it difficult for the compressor power to reach the preset limited power. Instead, the first target power of the compressor and the second target power of the electric heater are calculated and estimated first. The sum of the first target power of the compressor and the second target power of the electric heater is equal to the preset limited power. The calculation method of the rated power of the compressor has been given before, or the basic information of the compressor can be directly viewed by looking at the nameplate on the compressor. It is possible to determine whether the rated power of the compressor can meet the preset limited power. When the rated power of the compressor does not meet the requirements, the compressor power is controlled and the electric heating power level is fixed to meet the requirements. This requires understanding the compressor power control method. This proposal adopts the frequency adjustment method for the variable frequency compressor. The frequency is adjusted to change the compressor speed, thereby adjusting the power. For example, a multi-function water heater requires a power limit of 6KW, the rated power of the compressor is 3.5KW, and the power level of the electric heater is 2+2KW. Even if the compressor power is controlled to the maximum power alone, it cannot meet the requirement. You can reduce the compressor power while turning off the electric heater. When the compressor power is 2KW, turn on the electric heater to 4KW. After running for a period of time, the preset power limit can be reached.
