[0037] The specific implementation of the present application is further described below with reference to the accompanying drawings.

[0038] It is easy to understand that according to the technical solution of the present application, without changing the essential spirit of the present application, a variety of structural modes and implementation modes that can be replaced by those skilled in the art can be replaced with each other. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as the entirety of the present application or as a limitation or restriction on the technical solution of the application.

[0039] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0040] This embodiment provides a household technology system antifreeze control method, which can be applied to indoor control or remote monitoring control of household technology systems, such as Figure 1 As shown, the method includes:

[0041] S100: Obtain the outdoor temperature value.

[0042] Specifically, the outdoor temperature value may be monitored by a temperature sensor or the like disposed on an outdoor wall.

[0043] S200: If the outdoor temperature value is less than a first set threshold, the electric heating power circuit breaker is controlled to close to start the electric heating operation; wherein the electric heating is wound around the surface of the outdoor pipeline.

[0044] The first set threshold value can be selected based on experience or manually set, for example, 5°C. Electric heating can be in the form of a cable, wound around the outer wall of the outdoor pipe. Electric heating uses electric heating energy to supplement the heat lost by the outdoor pipe in the cold outdoors to maintain a reasonable temperature of the flowing medium inside the outdoor pipe. Electric heating has a long thermal stability time and has the advantages of high thermal efficiency, energy saving, easy installation, no pollution, long service life and automatic control.

[0045] S300: Obtain the outdoor pipe water temperature value.

[0046] Specifically, the water temperature value of the outdoor pipeline can be monitored by a temperature sensor or the like arranged in the outdoor pipeline.

[0047] S400: If the outdoor pipe water temperature is within the range of the first set threshold and the second set threshold, the electric heating is controlled to continue to operate.

[0048] The second set threshold value can be selected based on an empirical value or manually set, for example, 10°C.

[0049] The above scheme of the present application, by winding electric heating on the outer surface of the outdoor pipe of the air-cooled heat pump, and obtaining the outdoor temperature value and the outdoor pipe water temperature value at the same time, if the outdoor temperature value is less than the first set threshold, the electric heating power circuit breaker is controlled to close, and the electric heating operation is started; if the outdoor pipe water temperature value is within the range of the first set threshold and the second set threshold, the electric heating is controlled to continue to work. Through the scheme of the present application, the outdoor pipe is heated by electric heating, and the air-cooled heat pump does not need to be turned on all the time, thereby achieving the effect of reducing energy consumption.

[0050] Furthermore, if Figure 2 As shown, the household technology system antifreeze control method further includes:

[0051] S500: updating the outdoor pipeline water temperature value in real time.

[0052] If the electric heating is turned on to heat the outdoor pipe, the water temperature of the outdoor pipe will change. This solution collects the outdoor pipe water temperature in real time and updates it immediately.

[0053] S600: If the outdoor pipeline water temperature value is greater than the second set threshold, the electric heating power circuit breaker is controlled to be disconnected to turn off the electric heating.

[0054] That is, by using electric heating, the outdoor pipe water temperature can reach above 10°C, then the electric heating can be turned off to further save energy.

[0055] S700: Obtain the working duration of the electric heating.

[0056] By recording the start-up time of the controlled electric heating, the working duration of the electric heating can be obtained.

[0057] S800: If the working duration exceeds the set time and the outdoor pipe water temperature value is always less than the first set threshold, the air-cooled heat pump is controlled to start.

[0058] The set time can be selected according to the experience value of the antifreeze situation, for example, ten minutes. If the outdoor pipe water temperature still does not reach the first set temperature value required for antifreeze after the electric heating is set for a long time, the air-cooled heat pump will be turned on at this time.

[0059] S900: After the air-cooled heat pump is started, it is continuously determined whether the outdoor pipe water temperature value is greater than the first set threshold.

[0060] S110: If the judgment result is yes, the air-cooled heat pump is controlled to be turned off.

[0061] That is, if the outdoor pipe water temperature rises and reaches 5°C after the air-cooled heat pump is started, the air-cooled heat pump can be shut down in time to reduce energy consumption.

[0062] S120: If the outdoor temperature value is greater than the first set threshold, the electric heating power circuit breaker is controlled to be disconnected to turn off the electric heating.

[0063] If the outdoor temperature reaches the first set threshold, it means that the outdoor temperature is not low and no antifreeze is needed. At this time, the electric heating can be turned off and there is no need to turn on the air-cooled heat pump.

[0064] Preferably, in the above solution, the working status of the electric heating and air-cooled heat pump is sent to the mobile terminal and the cloud server. Thus, the user can remotely control the start or stop of the antifreeze mode of the household technology system through the mobile terminal, and can also know the working status of the household technology system in time.

[0065] Some embodiments of the present application also provide a household technology system antifreeze control device, such as Figure 3 and Figure 4 As shown, it includes a controller 100 and:

[0066] An outdoor temperature sensor probe 201 is used to detect the outdoor temperature value and send it to the controller 100;

[0067] The outdoor pipe water temperature sensor 202 is used to detect the outdoor pipe water temperature value and send it to the controller 100;

[0068] The electric heat tracing 200 is wound around the surface of the outdoor pipeline, and an electric heat tracing power circuit breaker 300 is provided between the electric heat tracing power supply and the power supply;

[0069] The controller 100 is connected to the outdoor temperature sensor probe 201, the outdoor pipe water temperature sensor 202 and the electric heating power supply circuit breaker 300, and the controller 100 executes any of the above-mentioned household technology system antifreeze control methods.

[0070] The present application scheme is further optimized on the basis of the existing household technology system automatic control architecture, and an outdoor temperature sensor probe 201 and an outdoor pipe water temperature sensor 202 are added. The temperature sensor probes are respectively arranged on the outdoor wall and the outdoor air conditioning water supply and return main pipe to detect the outdoor temperature and the water temperature in the outdoor pipe. In a specific example, when the outdoor temperature is lower than 5°C, the controller 100 sends a signal to close the electric heating power circuit breaker 300, and the electric heating 200 starts working. When the temperature is higher than 10°C, the connection between the electric heating and the power supply is closed. When the electric heating 200 still cannot maintain the outdoor pipe water temperature above 5°C after starting, the controller 100 sends a command to start the air-cooled heat pump 400, and the air-cooled heat pump 400 operates in the antifreeze mode. If the system presets the water temperature to 5°C, the water temperature in the outdoor pipe is kept not lower than 5°C by running the air-cooled heat pump 400.
