[0051] Figure 1is a schematic structural block diagram of a refrigerator 100 according to an embodiment of the present application. Referring to Figure 1 The refrigerator 100 of the embodiment of the present application can include an ice maker 110 and a controller 120.

[0052] In addition, the refrigerator 100 can further include a communication module 130. The communication module 130 can be connected with the controller 120 and an external terminal device respectively, for realizing communication between the controller 120 and the terminal device. The terminal device can be a control terminal of the refrigerator 100, on which an application (App) for controlling the refrigerator 100 can be installed. The control terminal can be, for example, a mobile device, a computer, or a vehicle-mounted device built in a floating car, or any combination thereof. In some embodiments, the mobile device can include, for example, a remote controller, a mobile phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, or any combination thereof.

[0053] The communication module 130 can be configured as a wireless communication module and / or a wired communication module, which can be set according to actual application requirements, and the embodiments of the present application do not make specific limitations thereon. When the communication module 130 is configured as a wireless communication module, it can realize communication between the controller 120 and the terminal device through a Wi-Fi module, a Bluetooth module, or a wireless radio frequency module.

[0054] The ice maker 110 can be installed in the interior of the refrigerator. Specifically, the ice maker 110 can be arranged in the freezer compartment of the refrigerator 100, so as to make ice cubes by means of the cold quantity of the refrigerator 100.

[0055] The controller 120 can include a memory 121 and a processor 122. The memory 121 stores a machine-executable program, which is executed by the processor 122 to realize the refrigerator reservation ice making method according to any one of the following embodiments or any combination of a plurality of embodiments.

[0056] Figure 2 is a schematic flow chart of a refrigerator reservation ice making method according to an embodiment of the present application. The refrigerator reservation ice making method of the embodiment can be applied to the refrigerator 100 described above. Referring to Figure 2 The refrigerator reservation ice making method of the embodiment can include the following steps S202 to S208.

[0057] In step S202, a use parameter of the refrigerator 100 is acquired.

[0058] The use parameter of the refrigerator 100 in this step can include location information and a reservation ice taking time point. The location information is the administrative region of the area where the refrigerator 100 is currently located, for example, in China, the area where the refrigerator is located can specifically include a province / autonomous region / municipality directly under the Central Government, a city / autonomous prefecture / district, and a county / autonomous county, etc.

[0059] Step S204, determine the time-of-use electricity price area where the refrigerator is located based on the location information.

[0060] The time-of-use electricity price area in this step refers to an administrative region that implements a time-of-use electricity price policy. The time-of-use electricity price policy is also known as a peak-valley electricity price policy, that is, according to the load change of the power grid, 24 hours a day is divided into peak, low, and other time periods, and different electricity price levels are formulated for each time period to encourage residents to reasonably arrange electricity use, reduce peak and fill valley, and improve the utilization efficiency of power resources.

[0061] Step S206, obtain the electricity price information of the time-of-use electricity price area, and determine the electricity price peak period start time point and the electricity price valley period start time point of the time-of-use electricity price area according to the electricity price information.

[0062] Among them, the electricity price peak period start time point to the electricity price valley period start time point of the day is the peak electricity price period, and the electricity price valley period start time point to the electricity price peak period start time point of the next day is the valley electricity price period. Specifically, the electricity price information can be obtained according to the time-of-use electricity price policy implemented in the time-of-use electricity price area. For example, assuming that the time-of-use electricity price policy of a certain place stipulates that the peak electricity price period is 8:00-22:00, and the valley electricity price period is 22:00-the next day 8:00, then the electricity price peak period start time point of the place every day is 8:00, and the electricity price valley period start time point is 22:00.

[0063] Step S208, determine the start ice-making time point based on the ice reservation time point, the electricity price peak period start time point, and the electricity price valley period start time point.

[0064] The embodiment of the application can obtain the location information of the refrigerator 100 and the ice reservation time point, determine the time-of-use electricity price area where the refrigerator is located based on the location information, and then obtain the electricity price information of the time-of-use electricity price area where the refrigerator is located, and determine the electricity price peak period start time point and the electricity price valley period start time point of the time-of-use electricity price area according to the obtained electricity price information, and then determine the start ice-making time based on the ice reservation time, the electricity price peak period start time point, and the electricity price valley period start time point. Based on the ice reservation method of the refrigerator according to the embodiment of the application, the time period of the time-of-use electricity price and the ice reservation time point are comprehensively considered, and the optimal start ice-making time point is selected, which not only meets the user's demand for ice reservation, but also saves electricity and reduces the pressure on the power supply network of the national power grid. At the same time, during the entire ice-making process, the user only needs to give the ice reservation time point, and the reasonable start ice-making time point can be determined intelligently, without the need for the user to operate too much, and the user's experience is good. Compared with the prior art in the fields of smart home, smart home, smart home appliance, etc., the scheme of the application realizes the intelligent regulation and control of the refrigerator ice maker, and further improves the intelligent level of the refrigerator.

[0065] For step S202, in some embodiments, a communication connection between the refrigerator 100 and a terminal device can be established, and then the use parameter of the refrigerator 100 is acquired from the terminal device. Specifically, the communication connection between the controller 120 of the refrigerator 100 and the terminal device can be established through the communication module 130 of the refrigerator 100. The terminal device can be a control terminal of the refrigerator 100, and an App for controlling the refrigerator can be installed thereon. The control terminal can be, for example, a mobile device, a computer, or a vehicle-mounted device built in a floating car, or any combination thereof. In some embodiments, the mobile device can include, for example, a remote controller, a mobile phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, or any combination thereof. In this embodiment, the use parameter of the refrigerator 100 can be directly acquired from the terminal device through the communication module 130, and the acquisition method is simpler and more accurate, which helps to improve the efficiency and accuracy of the ice making reservation.

[0066] The communication module 130 can be configured as a wireless communication module and / or a wired communication module, and can be specifically set according to actual application requirements, which is not limited in the embodiments of the present application. When the communication module 130 is configured as a wireless communication module, it can realize the communication between the controller 120 and the terminal device through a Wi-Fi module, a Bluetooth module, or a wireless radio frequency module.

[0067] In some embodiments, the use parameter of the refrigerator 100 in step S202 can also include a current time point. At this time, when the start ice making time point is determined based on the ice taking reservation time point, the peak electricity price period start time point, and the valley electricity price period start time point, first, it can be judged whether the first time difference between the ice taking reservation time point and the current time point is greater than or equal to the preset time length, and then the start ice making time point is determined according to the judgment result. The reservation time length is the minimum time length required for current ice making, which can be preset according to the ice making demand in actual application. For example, the lower the temperature of the refrigerator compartment, the smaller the ice box of the ice maker, the less the amount of water added during ice making, the smaller the ice block to be made, the faster the ice making speed, and the less the required ice making time. In an illustrative embodiment, the reservation time length can be set to 4 hours.

[0068] In the process of determining the start ice making time point according to the judgment result, if the first time difference is greater than or equal to the preset time length, that is, the ice taking reservation time point can meet the minimum time length requirement for current ice making, at this time, whether the ice taking reservation time point is in the valley electricity price period can be judged based on the peak electricity price period start time point and the valley electricity price period start time point, and when the ice taking reservation time point is in the valley electricity price period, the time point of the preset time length before the ice taking reservation time point is calculated to obtain the start ice making time point, so that ice making is started according to the obtained start ice making time point, so that the entire ice making process is controlled in the valley electricity price period, which helps to save electricity cost.

[0069] Further, if the first time difference is less than the preset time length, i.e., the ice reservation time point does not meet the minimum time length requirement for current ice making, a first reminder message can be output to remind the user that the reserved ice making time is insufficient and to re-reserve. In some embodiments, the first reminder message can be pushed to the terminal device, and the first reminder message can be pushed to the user through a pop-up window. Similarly, the first reminder message can also be played through the voice broadcast device of the terminal device.

[0070] Considering that the freshness of ice cubes decreases with the increase of the holding time of the ice cubes, and the energy consumed for maintaining the ice cube state for a duration increases significantly with the increase of the holding time of the ice cubes, in some embodiments, after the step of determining whether the ice reservation time point is in the valley electricity price period, the following steps can be further included:

[0071] If the ice reservation time point is not in the valley electricity price period, it is further determined whether a second time difference between the ice reservation time point and the start time point of the peak electricity price period exceeds a preset time length, and then the start time point of ice making is obtained by calculating the time point of the preset time length before the ice reservation time point when the second time difference exceeds the preset time length. In this embodiment, when the ice reservation time point is not in the valley electricity price period and the second time difference between the ice reservation time point and the start time point of the peak electricity price period exceeds the preset time length, the electricity price factor is no longer considered, and the time point of the preset time length before the ice reservation time point is taken as the start time point of ice making, thereby ensuring the freshness of the ice cubes and avoiding energy loss caused by the excessive duration of maintaining the ice cube state.

[0072] In some further embodiments, if the second time difference is less than or equal to the preset time length, a reference time point can be calculated according to the start time point of the peak electricity price period and the preset time length, and then it is determined whether the current time point is earlier than the reference time point, and the reference time point is taken as the start time point of ice making when the current time point is earlier than the reference time point, and the current time point is taken as the start time point of ice making when the current time point is later than the reference time point, so that the determined start time point of ice making is more reasonable, thereby further saving electricity costs.

[0073] In some embodiments, when the reference time point is calculated according to the start time point of the peak electricity price period and the preset time length, the time point of the preset time length before the start time point of the peak electricity price period can be calculated to obtain the reference time point. The reference time calculation method of this embodiment is simple and helps to determine the start time point of ice making.

[0074] Further, before step S204, the following step can also be included: determining whether the area where the refrigerator is located implements a time-of-use electricity price policy based on the location information; if the area where the refrigerator is located implements a time-of-use electricity price policy, step S204 is executed. If the area where the refrigerator is located does not implement a time-of-use electricity price policy, it can be determined whether the third time difference between the ice taking reservation time point and the current time point is greater than or equal to the preset time length, and when the third time difference is greater than or equal to the preset time length, the time point of the preset time length before the ice taking reservation time point is calculated to obtain the ice making start time point. If the third time difference is less than the preset time length, a second reminder message can be output to remind the user that the ice making time is insufficient. In some embodiments, the second reminder message can be pushed to the terminal device, and the second reminder message can be pushed to the user through a pop-up window. Similarly, the second reminder message can also be played through the voice broadcast device of the terminal device.

[0075] In some areas, especially in the northern region, the temperature drops every winter, and heating is needed to ensure human health. The duration of heating required each year is the heating season, which is generally from November to March of the next year. The duration of the other time when heating is not required is the non-heating season. Specifically, the heating season of the time-of-use electricity price area can be determined according to the time-of-use electricity price policy. The electricity price information of the heating season is usually different from that of the non-heating season. In order to determine a more optimized ice making start time point, in some embodiments, the use parameters of the refrigerator 100 also include current date information, and step S206 can further include the following steps: determining whether the time-of-use electricity price area is in the heating season according to the date information, if the time-of-use electricity price area is in the heating season, obtaining the heating electricity price information of the time-of-use electricity price area in the heating season, and determining the electricity price peak period start time point and the electricity price valley period start time point of the time-of-use electricity price area in the heating season according to the heating electricity price information; otherwise, if the time-of-use electricity price area is in the non-heating season, obtaining the non-heating electricity price information of the time-of-use electricity price area in the non-heating season, and determining the electricity price peak period start time point and the electricity price valley period start time point of the time-of-use electricity price area in the non-heating season according to the non-heating electricity price information. By using the scheme of the present embodiment, the ice making start time point can be determined in combination with the heating factor of the current area where the refrigerator 100 is located, so that a more optimized ice making start time point can be obtained.
