[0058] In some cases, the current multi-group pipe multi-split air conditioner can not only be matched with an air conditioner indoor unit, but also can be matched with a domestic hot water terminal. With the promotion of energy saving policies in various countries, the domestic hot water terminal shows that its power consumption can help consumers to more visually understand its energy consumption, guide consumers to use energy-savingly, and the government gives a certain amount of subsidies.

[0059] For a multi-group pipe multi-split air conditioner, the combination of indoor units is very diverse, and it is difficult to reasonably display the power consumption of each indoor unit terminal. Among them, the water tank electric heating is powered separately, and customers will customize the related power electric heating according to the demand, and there is a certain contradiction between the statistical power consumption and the large-scale production control.

[0060] Based on the above situation, the embodiments of the present application propose a water heater power detection control method, a controller, a water heater and a storage medium, which aims to reduce the difficulty of large-scale production control to a certain extent, and solve the problem that large-scale production is not easy to control.

[0067] In an embodiment, since the water heater can heat water by the electric heating mode in addition to the heat pump mode, in order to determine the water tank power of the water tank, the electric heating power of the water heater needs to be determined, and the target electric heating resistance corresponding to the target electric heating specification can be determined according to the target electric heating specification after the target electric heating specification of the water heater is determined, and the electric heating current of the water heater also needs to be obtained, so that the electric heating power of the water tank can be calculated according to the electric heating current and the target electric heating resistance and according to the power calculation formula, so that the water tank power of the water tank can be obtained according to the electric heating power and the outdoor unit distribution power, and after the water tank power of the water tank is calculated, the water tank power is used to calculate the stage power consumption of each time stage, and then the stage power consumption is superimposed on the basis of the pre-stored power value, so that the total power consumption value of the water heater is obtained.

[0068] It is worth noting that, since the embodiment of the present application can determine the corresponding target electric heating resistance according to the target electric heating specification, and the matching relationship between the two parameters can reduce the difficulty of large-scale production control to a certain extent, and can accurately understand the water tank consumption components, and solve the problem of difficult control in large-scale production.

[0069] In an embodiment, the unit of the target electric heating specification can be watts or kilowatts, and the unit of the target electric heating resistance can be ohms or kilo-ohms, and the target electric heating resistance and the target electric heating specification can be negatively correlated, that is, the larger the target electric heating specification, the smaller the target electric heating resistance, and the smaller the target electric heating specification, the larger the target electric heating resistance.

[0070] In an embodiment, the embodiment of the present application can find the target electric heating resistance from the table according to the target electric heating specification by table lookup, or can input the target electric heating specification into the calculation formula to obtain the target electric heating resistance.

[0072] In addition, it should be noted that, regarding the above step S110, it can include but is not limited to two schemes, wherein the first scheme can refer to the following FIG. 2 and FIG. 3, and the second scheme can refer to the following FIG. 4 and FIG. 5.

[0073] The first scheme is as follows:

[0074] As shown in FIG. 2, FIG. 2 is a flowchart of the electric quantity detection control method of the water heater according to another embodiment of the present application. As to the determination of the target electric heating specification of the water heater in step S110, it can include but is not limited to step S210 and step S220.

[0075] In step S210, a preset electric heating specification is obtained, wherein the preset electric heating specification is determined by the user-selected electric heating requirement.

[0076] In step S220, the preset electric heating specification is taken as the target electric heating specification of the water heater.

[0077] In an embodiment, as to the target electric heating specification, it can be determined by the user selection. Specifically, when the user selects the electric heating requirement, the user can select a corresponding preset electric heating specification, and then the preset electric heating specification is taken as the target electric heating specification of the water heater.

[0078] In addition, as shown in FIG. 3, FIG. 3 is a flowchart of the electric quantity detection control method of the water heater according to another embodiment of the present application. As to the determination of the target electric heating resistance value based on the target electric heating specification in step S110, it can include but is not limited to step S310 and step S320.

[0079] In step S310, a first preset table is obtained, wherein the first preset table includes a plurality of electric heating specifications and electric heating resistance values, and one electric heating specification corresponds to one electric heating resistance value.

[0080] In step S320, the target electric heating resistance value corresponding to the target electric heating specification is determined from the first preset table.

[0081] In an embodiment, the embodiment of the present application can set a first preset table, which records a plurality of electric heating specifications and a plurality of electric heating resistance values, and the electric heating specifications and the electric heating resistance values correspond to each other. After obtaining the target electric heating specification, the embodiment of the present application can filter out the target electric heating resistance value corresponding to the target electric heating specification from the first preset table by the table lookup method.

[0082] The second scheme is as follows:

[0083] As shown in FIG. 4, FIG. 4 is a flowchart of the electric quantity detection control method of the water heater according to another embodiment of the present application. As to the determination of the target electric heating specification of the water heater in step S110, it can include but is not limited to step S410 and step S420.

[0084] In step S410, a historical electric heating current in a case where the water heater receives an outdoor unit working signal and starts electric heating is obtained.

[0085] Step S420, determining the target electric heating specification of the water heater according to the historical electric heating current.

[0086] In an embodiment, the water heater detects the historical electric heating current when it receives the outdoor unit working signal for the first few times and starts electric heating, and then determines the target electric heating specification of the water heater according to the historical electric heating current by table lookup or calculation.

[0087] In an embodiment, the embodiment of the present application can find the target electric heating specification from the table according to the historical electric heating current by table lookup, or input the historical electric heating current into a calculation formula to obtain the target electric heating specification.

[0088] As shown in FIG. 5, FIG. 5 is a flowchart of the electric quantity detection control method of the water heater according to another embodiment of the present application. As to step S420, it can include but is not limited to step S510, step S520 and step S530.

[0089] Step S510, obtaining a second preset table, wherein the second preset table includes a plurality of electric heating specifications, standard current parameters and electric heating resistance values, and one electric heating specification corresponds to one standard current parameter and one electric heating resistance value;

[0090] Step S520, determining the corresponding target standard current parameter according to the historical electric heating current;

[0091] Step S530, determining the target electric heating specification corresponding to the target standard current parameter from the second preset table.

[0092] In an embodiment, the embodiment of the present application can set a second preset table, which records a plurality of electric heating specifications, a plurality of standard current parameters and a plurality of electric heating resistance values, and the electric heating specifications, the standard current parameters and the electric heating resistance values correspond to each other one by one. After obtaining the historical electric heating current, the embodiment of the present application can filter out the target electric heating specification corresponding to the historical electric heating current from the second preset table by table lookup.

[0093] In addition, in an embodiment, as to the determination of the target electric heating resistance value based on the target electric heating specification in step S110, it can be that the target electric heating resistance value corresponding to the target electric heating specification is determined from the second preset table by table lookup.

[0094] In addition, it should be noted that as to step S130, it can include but is not limited to the two power calculation methods shown in FIG. 6 or FIG. 7, which are as follows respectively:

[0095] As shown in FIG. 6, FIG. 6 is a flowchart of the electric quantity detection control method of the water heater according to another embodiment of the present application; as to the step S130, it can include but is not limited to step S610 and step S620.

[0096] The step S610 obtains the power loss of the electric control board, the electronic anode power and the communication power.

[0097] The step S620 superimposes the power allocated to the external machine, the power loss of the electric control board, the electric heating power, the electronic anode power and the communication power to obtain the water tank power of the water tank.

[0098] In an embodiment, since there are various devices in the water heater, there are various consumptions, and thus the water tank power can be calculated by the following formula: P tank = P CN + P control + P PTC + P Anode + P 通信 , wherein P tank is the water tank power, P CN is the power allocated to the external machine, i.e. the external machine power allocated to the water tank by the external machine, P control is the power loss of the electric control board, P PTC is the electric heating power, P Anode is the electronic anode power, and P 通信 is the communication power.

[0099] In an embodiment, the power allocated to the external machine is obtained in the following manner: the external machine transmits the external machine power to the indoor machine through the indoor-outdoor communication protocol, and the specific allocation principle is that the external machine calculates the proportion of the working indoor machine end (water tank) in the external machine power and then sends the proportion through the protocol.

[0100] In an embodiment, the power loss of the electric control board is related to the on-off state of the electric control board and the power voltage.

[0101] In an embodiment, the electronic anode power is zero or a second fixed power, wherein the second fixed power is a positive number. For example, the power value of the parameter table is changed according to the configuration scheme when the electronic anode is selected, and the default value is 0, and the reference value is 0.6W when the electronic anode is selected.

[0102] In an embodiment, the communication power can be WIFI power, Bluetooth power or other types of power.

[0103] As shown in FIG. 7, FIG. 7 is a flowchart of the electric quantity detection control method of the water heater according to another embodiment of the present application; as to the step S130, it can include but is not limited to step S710 and step S720.

[0104] Step S710: Obtain the power loss of the electronic control board, the power of the electronic anode, the communication power, and the correction power;

[0105] Step S720: The power allocated to the external unit, the power loss of the electronic control board, the power of electric heating, the power of the electronic anode, the communication power, and the correction power are superimposed to obtain the power of the water tank.

[0106] In one embodiment, since there are multiple components in the water heater, there will be multiple types of power consumption. Furthermore, due to potential deviations in actual applications, the water tank power can be calculated using the following formula: P tank =P CN +P control +P PTC +P Anode +P 通信 +C, where P tank For the water tank power, P CN Power is allocated to the outdoor unit, that is, the power of the outdoor unit allocated to the water tank, P control P represents the power loss of the electronic control board. PTC P represents the electric heating power. Anode For electron anode power, P 通信 C is the communication power, and C is the correction power.

[0107] In one embodiment, the outdoor unit's power allocation is obtained as follows: the outdoor unit transmits its power to the indoor unit via an indoor-outdoor communication protocol. The specific allocation principle is calculated by the outdoor unit based on the proportion of the indoor unit's power at the working terminal (water tank) in the outdoor unit's power, and then sent using the protocol.

[0108] In one embodiment, the power loss of the control board is related to the power-on / off state of the control board and the power supply voltage.

[0109] In one embodiment, the electronic anode power is zero or a second fixed power, wherein the second fixed power is a positive number. For example, the power value of the selected electronic anode is changed according to the configuration scheme in the parameter table, with a default value of 0 and a reference value of 0.6W during selection.

[0110] In one embodiment, the communication power can be Wi-Fi power, Bluetooth power, or other types of power.

[0111] Additionally, as shown in Figure 8, which is a flowchart of a water heater power detection and control method provided in another embodiment of this application; regarding the power loss of the control board, the acquisition process includes, but is not limited to, steps S810, S820 and S830.

[0112] Step S810: Obtain the current status of the electronic control board;

[0113] Step S820, when the electric control board is in the shutdown state, determining the electric control board loss power as a first fixed power;

[0114] Step S830, when the electric control board is in the startup state, acquiring the power supply voltage of the electric control board, and determining the electric control board loss power according to the power supply voltage.

[0115] In an embodiment, for the determination process of the electric control board loss power, the following can be performed: if the electric control board is in the shutdown state, it indicates that the electric control board only retains the wake-up function or other necessary functions, and therefore the loss power at this time is very low, so the electric control board loss power can be determined as a first fixed power with a smaller value; if the electric control board is in the startup state, since the power supply voltage will affect the power of each device, the embodiments of the present application will determine the size of the electric control board loss power according to the size of the power supply voltage.

[0116] In addition, in an embodiment, when a preset condition is met, the embodiments of the present application will respond to update the electric quantity value stored in the controller, wherein the preset condition includes at least one of the following:

[0117] 1. The water heater is in the startup state and is triggered every first preset time interval;

[0118] 2. The water heater is in the shutdown state and is triggered every second preset time interval, wherein the second preset time interval is greater than the first preset time interval;

[0119] 3. The water heater receives a shutdown instruction;

[0120] 4. The phase electric quantity reaches a preset value;

[0121] 5. The electric quantity value recorded in the controller reaches a maximum range value.

[0122] Based on the electric quantity detection control method of the water heater of each of the above embodiments, the overall embodiment of the electric quantity detection control method of the water heater of the present application is proposed as follows.

[0126] The customer has a large demand for individualization of electric heating power, and will choose different power electric heating. However, the control logic needs to be highly unified from the production control point of view, so it is necessary to use a suitable scheme to realize the electric quantity detection under the individualization of electric heating selection.
