[0047] The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, rather than to limit the present application.

[0048] The embodiments of the present application will be described below with reference to the accompanying drawings. Those of ordinary skill in the art will know that with the development of technology and the emergence of new scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0049] The terms "first", "second", etc. in the specification of the present application and the above accompanying drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances, which is only a way of distinguishing when describing objects with the same attributes in the embodiments of the present application. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion, so that a process, method, system, product or device including a series of units does not have to be limited to those units, but may include other units not clearly listed or inherent to these processes, methods, products or devices.

[0050] See Figure 1 , Figure 1 is a schematic structural diagram of waterway electric heating of a heat pump air conditioner in the prior art. As Figure 1As shown in the figure, the waterway electric heating of the heat pump air conditioner includes a circuit part A and a waterway part B. The circuit part A is composed of a heating component A-1, a thermostat A-2, a fuse A-3, and a control switch A-4 connected in series, and the waterway part B is composed of a water pump B-1 and a flowmeter B-2 connected in series. It should be noted that Figure 1 in which L represents the live wire and N represents the neutral wire.

[0051] The inventor found through research that currently, the waterway electric heating in the heat pump air conditioner only adopts a two-stage protection scheme of the thermostat A-2 and the fuse A-3. Specifically, when the waterway temperature reaches a relatively high level, the thermostat A-2 disconnects, and when the waterway temperature reaches an even higher level, the fuse A-3 disconnects. Of course, the thermostat A-2 can be reset when the waterway temperature drops after it disconnects, while the fuse A-3 cannot be restored after it disconnects. The temperature detection of this scheme has hysteresis, and it is easy to cause a fire when the open-circuit protection is lagging or the option of the thermostat A-2 is too high.

[0052] To solve the above problems, the embodiment of the present application provides a control method for waterway electric heating. The following will introduce the control method for waterway electric heating in the embodiment of the present application in detail with reference to the drawings.

[0053] See Figure 2 , Figure 2 which is a schematic flow chart of a control method for waterway electric heating provided by the embodiment of the present application. As Figure 2 shown, a control method for waterway electric heating provided by the embodiment of the present application may include steps S10 to S30, and the following will describe these steps in detail respectively.

[0054] S10, collect the operating parameters of the waterway electric heating, and the operating parameters can characterize the waterway temperature.

[0055] The control method for waterway electric heating provided by the embodiment of the present application can be applied to the control board of the heat pump air conditioner. The control board executes the control scheme of the embodiment of the present application to cool down in time during the operation of the waterway electric heating, avoid dry burning, reduce the fire hazard, and ensure the safe use of the air conditioner.

[0056] Specifically, in the embodiment of the present application, when the waterway electric heating starts to operate, the operating parameters of the waterway electric heating are collected regularly, and based on these operating parameters, the temperature of the waterway part B in the waterway electric heating, that is, the waterway temperature, can be obtained.

[0057] In practical applications, it can be determined whether the waterway electric heating starts to operate by monitoring the on-off state of the control switch A-4. Among them, when the control switch A-4 is in the on state, it can be determined that the waterway electric heating starts to operate. On the contrary, when the control switch A-4 is in the off state, it can be determined that the waterway electric heating does not start to operate.

[0058] In this regard, when the control switch A-4 is in the on state, the control board of the heat pump air conditioner can regularly collect the operating parameters of the waterway electric heating to obtain the waterway temperature.

[0059] S20. Determine the matching water pump speed according to the operating parameters.

[0060] Specifically, in the embodiment of the present application, when the waterway temperature is obtained through the operating parameters of the waterway electric heating, the corresponding water pump speed can be matched. Among them, the water pump speed is positively correlated with the waterway temperature. That is to say, the higher the waterway temperature obtained through the operating parameters, the greater the water pump speed.

[0061] S30. Control the operation of the water pump at the water pump speed so that the waterway temperature shows a downward trend.

[0062] Specifically, in the embodiment of the present application, after the water pump speed is matched through the operating parameters, the operation of the water pump B-1 can be controlled at the water pump speed, that is, within a certain time, the water pump B-1 is controlled to reach the water pump speed and maintained at that speed to increase the flow rate of the waterway part B in the waterway electric heating, so that the waterway temperature shows a downward trend.

[0063] Of course, in practical applications, after controlling the water pump B-1 to operate at the water pump speed and the waterway temperature drops, further return to execute step S10, that is, collect the operating parameters of the waterway electric heating again, further match the water pump speed, and then control the operation of the water pump B-1. Through such cyclic control, the temperature can be controlled in real time during the start-up process of the waterway electric heating, and the temperature can be reduced in time to avoid dry burning.

[0064] In a possible implementation, the on / off state of the temperature controller A-2 can be used to determine whether the waterway temperature reaches a relatively high level, so as to force the water pump B-1 to operate at the maximum speed to ensure that the internal and external temperatures of the waterway electric heating are reduced in the shortest time.

[0065] See Figure 3 , Figure 3 which is another flowchart of a control method for waterway electric heating provided by the embodiment of the present application. As Figure 3 shown, for a control method for waterway electric heating provided by the embodiment of the present application, in step S10, "collect the operating parameters of the waterway electric heating", the following steps can be adopted:

[0066] S101. Monitor the current working state of the temperature controller.

[0067] Correspondingly, step S20, "determine the matching water pump speed according to the operating parameters", can adopt the following steps:

[0068] S201. When the current working state of the thermostat switches from the on state to the off state, obtain the maximum speed of the water pump and use the maximum speed as the water pump speed.

[0069] Specifically, when the water path temperature reaches a relatively high temperature, the thermostat A-2 will disconnect. After the thermostat A-2 disconnects and the water path temperature decreases, it can be reset. That is to say, after the water path electric heating starts to work, the working state of the thermostat A-2 will maintain the on state. Taking the set temperature threshold T-1 as an example, when the water path temperature reaches above the temperature threshold T-1, the thermostat A-2 will disconnect (i.e., the working state switches from the on state to the off state). Of course, when the water path temperature drops below the temperature threshold T-1, the thermostat will reset (i.e., the working state switches from the off state to the on state). Thus, by monitoring the working state of the thermostat A-2, it can be determined whether the water path temperature reaches above the temperature threshold T-1.

[0070] In this regard, in the embodiments of the present application, the current working state of the thermostat A-2 can be monitored in real time. When the current working state of the thermostat A-2 switches from the on state to the off state, it can be determined that the current water path temperature reaches above the temperature threshold T-1. At this time, the maximum speed of the pre-set water pump B-1 can be obtained. This maximum speed can be the rated speed of the water pump B-1, and further use this maximum speed as the water pump speed to control the operation of the water pump B-1.

[0071] Thus, when the thermostat A-2 disconnects, the water pump B-1 can be forced to operate at the maximum speed, thereby maximizing the water flow rate in the water path and quickly cooling down the water path electric heating.

[0072] Of course, on this basis, when it is monitored that the current working state of the thermostat A-2 switches from the off state to the on state, it can be determined that the current water path temperature drops below the temperature threshold T-1. At this time, the control instruction output to the water pump B-1 can be stopped, and the water pump B-1 will resume operating at the water pump speed in the original control logic, and the water path electric heating resumes normal operation.

[0073] In a possible implementation, when the water path electric heating is working normally, the speed of the water pump B-1 can be adjusted in real time according to the water path temperature to cool down the water path electric heating in a timely manner and maximize the avoidance of the occurrence of dry burning.

[0074] See Figure 4 , Figure 4 which is another flow schematic diagram of a control method for water path electric heating provided by the embodiments of the present application. As Figure 4 shown, for a control method for water path electric heating provided by the embodiments of the present application, in step S10, "collect the operation parameters of the water path electric heating", the following steps can also be included:

[0075] S102. Obtain the current waterway temperature output by the temperature sensor.

[0076] Correspondingly, step S20 "Determine the matching water pump speed according to the operating parameters" can also adopt the following steps:

[0077] S202. When the current working state of the thermostat is in the on state, determine the water pump speed according to the current waterway temperature.

[0078] In the embodiment of the present application, while monitoring the current working state of thermostat A-2, the current waterway temperature output by the temperature sensor is also obtained. Refer to Figure 5 , Figure 5 This is a schematic structural diagram of the waterway electric heating of a heat pump air conditioner provided by the embodiment of the present application. As Figure 5 shown, in the embodiment of the present application, a temperature sensor B-3 can be added to the waterway part B, and the temperature sensor B-3 is electrically connected to the control board of the heat pump air conditioner.

[0079] Specifically, the current temperature of the waterway part B (i.e., the current waterway temperature) can be collected in real time through the temperature sensor B-3. Then, when the current working state of the thermostat A-2 is in the on state, the water pump speed is determined according to the current waterway temperature. The water pump speed is positively correlated with the current waterway temperature, that is, the higher the current waterway temperature, the greater the water pump speed.

[0080] In a possible implementation, multiple speed gears corresponding to the waterway temperature can be set for the water pump B-1. After obtaining the current waterway temperature, the speed gear corresponding to the current waterway temperature (i.e., the current speed gear) can be determined, and then the speed of the current speed gear is used as the water pump speed.

[0081] In a possible implementation, in order to accurately adjust the water pump speed, the water pump speed can be determined according to the rising situation of the waterway temperature to quickly reduce the internal and external temperatures of the waterway electric heating. Refer to Figure 6 , Figure 6 This is a partial flowchart of a control method for waterway electric heating provided by the embodiment of the present application. As Figure 6 shown, in the embodiment of the present application, in step S202, "Determine the water pump speed according to the current waterway temperature" can adopt the following steps:

[0082] S2021. Retrieve the historical waterway temperature output by the temperature sensor.

[0083] S2022. Determine the change trend of the waterway temperature according to the current waterway temperature and the historical waterway temperature.

[0084] S2023, if the waterway temperature change trend is an upward trend and the upward rate corresponding to the upward trend is greater than the corresponding first threshold, determine the water pump speed according to the current waterway temperature and the upward rate. The water pump speed is positively correlated with the current waterway temperature and positively correlated with the upward rate.

[0085] Specifically, in the embodiments of the present application, the waterway temperature output by the temperature sensor at a historical moment (i.e., the historical waterway temperature) can be retrieved. For example, the n historical waterway temperatures before the current moment can be retrieved by the temperature sensor. Furthermore, a linear fitting curve is generated based on the current waterway temperature and the historical waterway temperatures, and the slope of the linear fitting curve is used as the waterway temperature change rate. If the waterway temperature change rate is greater than 0, it is determined that the waterway temperature change trend is an upward trend. On the contrary, if the waterway temperature change rate is less than 0, it is determined that the waterway temperature change trend is a downward trend.

[0086] Based on this, if the waterway temperature change trend is an upward trend and the waterway temperature change rate as the upward rate is greater than the corresponding first threshold (i.e., the change rate threshold), the water pump speed can be determined according to the current waterway temperature and the upward rate. The water pump speed is positively correlated with the current waterway temperature and positively correlated with the upward rate, that is, the higher the current waterway temperature, the greater the upward rate, and the greater the water pump speed.

[0087] In practical applications, different speed gears can be set for different waterway temperatures and upward rates. By matching the speed gears, the speed of the matched speed gear is used as the water pump speed.

[0088] In some scenarios, the embodiments of the present application can also forcibly turn off the waterway electric heating when the flow rate of the waterway is very small or even there is no water flow to prevent dry burning. For this, a control method for waterway electric heating provided by the embodiments of the present application may further include the following steps:

[0089] Obtain the current waterway flow rate output by the flow meter; when the current waterway flow rate is less than the corresponding second threshold, cut off the power supply of the waterway electric heating.

[0090] Specifically, in the embodiments of the present application, the flow meter B-2 can collect the current flow rate of the waterway part B in real time (i.e., the current waterway flow rate). After obtaining the current waterway flow rate output by the flow meter B-2, the current waterway flow rate is further compared with the corresponding second threshold (i.e., the flow rate threshold). When the current waterway flow rate is less than the corresponding second threshold, it can be determined that the flow rate of the waterway is very small or even there is no water flow. For example, when the current waterway flow rate is equal to 0, it can be determined that there is no water flow. At this time, the power supply of the waterway electric heating can be cut off, that is, the on-off state of the control switch A-4 is switched from the on state to the off state.

[0091] In some other scenarios, the embodiments of the present application can also forcibly turn off the waterway electric heating when the waterway is short of water to prevent dry burning. For this, a control method for waterway electric heating provided by the embodiments of the present application may further include the following steps:

[0092] Obtain the current waterway liquid level output by the liquid level switch, where the liquid level switch is pre-set in the waterway of the waterway electric heating;

[0093] When the current waterway liquid level is less than the corresponding third threshold, cut off the power supply of the waterway electric heating.

[0094] See Figure 7 , Figure 7 which is another schematic structural diagram of the waterway electric heating of a heat pump air conditioner provided by the embodiments of the present application. As Figure 7 shown, the embodiments of the present application can add a liquid level switch B-3 to the waterway part B, and the liquid level switch B-4 can collect the current liquid level of the waterway in real time (i.e., the current waterway liquid level).

[0095] After obtaining the current waterway liquid level output by the liquid level switch B-4, further compare the current waterway liquid level with the corresponding third threshold (i.e., the liquid level threshold). When the current waterway liquid level is less than the corresponding third threshold, it can be determined that the liquid level of the waterway is very low and in a water shortage state. At this time, the power supply of the waterway electric heating can be cut off, that is, the on-off state of the control switch A-4 is switched from the on state to the off state.

[0096] Through the above description, a control method for waterway electric heating provided by the embodiments of the present application can cool down in time during the operation of the waterway electric heating, avoid dry burning, reduce the fire hazard, and ensure the safety of air conditioner use.

[0097] The above introduces a control method for waterway electric heating provided by the embodiments of the present application. The following will introduce the device for executing the above control method for waterway electric heating.

[0105] When the current working state of the thermostat switches from the conducting state to the off state, obtain the maximum rotation speed of the water pump and use the maximum rotation speed as the rotation speed of the water pump.

[0111] Retrieve the historical waterway temperature output by the temperature sensor; determine the change trend of the waterway temperature according to the current waterway temperature and the historical waterway temperature; if the change trend of the waterway temperature is an upward trend and the upward rate corresponding to the upward trend is greater than the corresponding first threshold, determine the rotation speed of the water pump according to the current waterway temperature and the upward rate, and the rotation speed of the water pump is positively correlated with the current waterway temperature and positively correlated with the upward rate.

[0112] In a possible implementation, the water pump control module 30 is further configured to:
