[0050] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0051] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0052] The main solution of the embodiment of the present application is as follows: the refrigerator ice-making system includes a controller, an ice box, a water pressure sensor, a water inlet valve, and a water pipe; the water pipe connects the ice box, the water pressure sensor, and the water inlet valve, and the water pressure sensor is located between the ice box and the water inlet valve. The controller is connected to the water pressure sensor and the water inlet valve respectively. The controller of the present application obtains the current water inlet pressure of the water pipe via the water pressure sensor, selects a target water filling time associated with the current water inlet pressure from multiple preset water filling time durations, and controls the water inlet valve to open within the target water filling time duration to fill the ice box with water.

[0053] Since the existing technology fills water at a fixed time, it is affected by various interference factors such as water pressure, water valve opening, impurities in the water pipe, etc., which will cause the water filling amount of the ice box to be unstable, affecting the ice making effect, such as the ice cubes being too small or the ice cubes sticking together.

[0054] The present application provides a solution, in which the water filling time of the ice box is selected based on the current water inlet pressure of the water pipe, thereby realizing dynamic adjustment of the water filling time of the ice box according to the actual water inlet pressure. Compared with the fixed time water filling in the existing technology, the present application effectively reduces the influence of interference factors, improves the stability of the water filling amount of the ice box, and thus improves the ice making effect.

[0055] Based on this, the embodiment of the present application provides a refrigerator ice making system, referring to Figure 1 , Figure 1 This is a structural diagram of an embodiment of the refrigerator ice-making system of this application.

[0056] In this embodiment, the refrigerator ice-making system includes: a controller, an ice-making box 1 , a water pressure sensor 2 , a water inlet valve 3 and a water pipe 4 .

[0057] The water pipe 4 is connected to the ice box 1 , the water pressure sensor 2 and the water inlet valve 3 , and the water pressure sensor 2 is disposed between the ice box 1 and the water inlet valve 3 .

[0058] Among them, although Figure 1 Although not shown, it should be noted that the controller is connected to the water pressure sensor 2 and the water inlet valve 3 respectively to obtain pressure data collected by the water pressure sensor 2 and to control the water inlet valve 3 .

[0059] The ice box 1 is a component used to hold water and freeze it into ice cubes. It can be composed of multiple ice troughs, each corresponding to a block of ice. When water is poured into the troughs, it flows into these troughs. During the freezing process, the water gradually freezes within the troughs to form ice cubes.

[0060] The water pressure sensor 2 may be a sensor for real-time detection of the water pressure in the water pipe 4. The water pressure sensor 2 may convert the water pressure signal into an electrical signal and transmit the electrical signal to the controller.

[0061] The water inlet valve 3 can be a control component connecting the ice making box and the water pipe 4. The water inlet valve 3 can be opened or closed under the instruction of the controller, thereby controlling whether the water flow enters the ice making box 1.

[0062] The water pipe 4 may be a pipe connecting a water supply source and the water inlet valve 3 , and is responsible for transporting water from the water supply source to the ice making box 1 . Figure 1 The direction of the arrow in FIG. 1 is the direction in which water is transported from the water supply source to the ice making box 1 .

[0063] The controller is used to obtain the current water inlet pressure of the water pipe 4 through the water pressure sensor 2.

[0064] In a specific implementation, the water pressure sensor 2 can detect the water pressure in the water pipe 4 in real time, and convert the water pressure signal into an electrical signal and output it to the controller. The controller can obtain the current water inlet pressure of the water pipe 4 based on the electrical signal.

[0065] The controller is further configured to select a target water injection duration associated with the current water inlet pressure from a plurality of preset water injection durations.

[0066] In practice, during the development phase of a refrigerator's ice-making system, numerous water-injection experiments can be conducted, with pressure-time curves recorded at varying water inlet pressures to generate a standard pressure-time curve. In actual use, the controller can match the current water inlet pressure with the pre-stored standard pressure-time curve. Based on the matching results, the target water-injection time corresponding to the current water inlet pressure is determined.

[0067] In addition, the above-mentioned controller can be connected to the display panel of the refrigerator to display the queried target water filling time on the display target. When the water filling time corresponding to the current water inlet pressure is not queried, the corresponding prompt information can be output through the display panel of the refrigerator to inform the user, and the user can perform corresponding operations, such as manually setting the water filling time or increasing the water filling pressure.

[0068] The controller is further configured to control the water inlet valve 3 to open within the target water filling time to fill the ice making box 1 with water.

[0069] It should be noted that, after obtaining the target water filling time, the controller can control the water inlet valve 3 based on the target water filling time. Specifically, the controller can control the water inlet valve 3 to remain open during the target water filling time, so that water is continuously delivered from the water supply source to the ice making box 1 during the target water filling time.

[0070] Furthermore, in this embodiment, the refrigerator ice-making system further includes: a temperature sensor 5 .

[0071] The temperature sensor 5 is connected to the controller and the ice box 1 respectively.

[0072] The temperature sensor 5 can be installed between or near the ice grooves of the ice box 1 to monitor the temperature changes in the ice box 1 in real time. After the water is filled, the temperature sensor 5 can detect the rate of decrease of the water temperature in the ice grooves of the ice box 1 and the temperature when it is finally frozen.

[0073] The controller is further configured to control the water inlet valve 3 to close and stop filling water into the ice box 1 when the current water filling time of the ice box 1 reaches the target water filling time.

[0074] In a specific implementation, when the controller detects that the current water filling time reaches the target water filling time, it can control the water inlet valve 3 to close, thereby cutting off the passage between the water supply source and the ice making box 1 and stopping water filling into the ice making box 1.

[0075] The controller is further configured to obtain the current ice box temperature of the ice box 1 through the temperature sensor 5 when the closing time of the water inlet valve 3 reaches a preset closing time.

[0076] It should be noted that the above-mentioned preset shutdown time length can be a pre-set time length, such as 5 minutes.

[0077] In a specific implementation, the controller can communicate with the temperature sensor 5. Once the ice box 1 is filled with water, i.e., after the water inlet valve 3 is closed, the ice box 1 enters the cooling phase. Cold air from the refrigerator's refrigeration system circulates through the refrigeration pipes, gradually lowering the temperature of the ice box 1. The temperature sensor 5 of the ice box 1 monitors temperature changes in real time and feeds this data back to the controller. The controller then uses this data to determine the current temperature of the ice box 1.

[0078] The controller is further configured to control the ice making box 1 to make ice according to the current temperature of the ice making box.

[0079] It should be noted that, when the water level is normal, the water in ice box 1 needs to absorb sufficient cold energy during the cooling process to lower its temperature to the low temperature required for ice making. At this point, the temperature detected by temperature sensor 5 changes relatively smoothly, ultimately reaching a temperature range corresponding to the normal water level. When the water level is insufficient, the water's ability to absorb cold energy is relatively weak due to the small amount of water. The water in the ice box reaches a lower temperature in a relatively short period of time, causing the current ice box temperature detected by temperature sensor 5 to be low. This indicates that the water level in ice box 1 is insufficient to meet ice making requirements and that a certain amount of water needs to be added to ensure the size and quality of the ice cubes.

[0080] Based on this, the controller can control the ice-making process of the ice-making box 1 according to the current temperature of the ice-making box.

[0081] Specifically, the controller is further configured to determine whether the current temperature of the ice making box reaches a preset temperature threshold.

[0082] The controller is further configured to control the water inlet valve 3 to open when the current temperature of the ice making box does not reach a preset temperature threshold.

[0083] The controller is further configured to control the water inlet valve 3 to close when the opening time of the water inlet valve 3 reaches a preset opening time, so that the ice making box 1 starts making ice.

[0084] The controller is further configured to keep the water inlet valve 3 closed when the current temperature of the ice making box reaches a preset temperature threshold, so that the ice making box 1 starts making ice.

[0085] It should be noted that the above-mentioned preset temperature threshold may be a pre-set threshold used to measure whether the current temperature of the ice making box is low.

[0086] It is understandable that the preset opening time may be a calibrated value that has been pre-tested to ensure that the amount of water in the ice making box 1 can meet the ice making demand through one water replenishment, such as 0.5s.

[0087] In a specific implementation, the controller may compare the current ice box temperature with a preset temperature threshold to determine whether the current ice box temperature has reached the preset temperature threshold. If the current ice box temperature has not reached the preset temperature threshold, the controller may determine that the current ice box temperature is low, and further determine that the amount of water in ice box 1 does not meet ice making requirements. In this case, the controller may control water inlet valve 3 to open for a preset opening duration, and continue to fill ice box 1 with water during the preset opening duration to replenish water in ice box 1 and ensure the size and quality of the ice cubes. When the opening duration of water inlet valve 3 reaches the preset opening duration, the controller may control water inlet valve 3 to close, causing ice box 1 to begin making ice. When the current ice box temperature reaches the preset temperature threshold, the controller may determine that the amount of water in ice box 1 meets ice making requirements, and control water inlet valve 3 to remain closed, causing ice box 1 to begin making ice.

[0088] It should be understood that during the ice-making phase of ice box 1, cold air from the refrigerator's refrigeration system circulates through the refrigeration pipes, gradually lowering the temperature of ice box 1. The water within ice box 1 begins to freeze in the low-temperature environment, with ice crystals gradually forming and growing. Ice box 1's temperature sensor 5 monitors temperature changes in real time and feeds this data back to the controller. When the controller detects that the real-time temperature of ice box 1 has reached a preset ice-making temperature (e.g., approximately -5°C to -10°C) and the volume of the ice cubes has reached a certain size, it determines that the ice-making process is complete and enters the subsequent defrosting phase.

[0089] The refrigerator ice-making system of this embodiment includes: a controller, an ice-making box, a water pressure sensor, a water inlet valve, and a water pipe; the water pipe connects the ice-making box, the water pressure sensor, and the water inlet valve; the water pressure sensor is located between the ice-making box and the water inlet valve, and the controller is connected to the water pressure sensor and the water inlet valve, respectively. The controller of this embodiment obtains the current water inlet pressure of the water pipe through the water pressure sensor, selects a target water injection time associated with the current water inlet pressure from multiple preset water injection time periods, and controls the water inlet valve to open within the target water injection time period to inject water into the ice-making box. The water injection time of the ice-making box of this application is selected based on the current water inlet pressure of the water pipe, which enables the water injection time of the ice-making box to be dynamically adjusted according to the actual water inlet pressure. Compared with the fixed time water injection of the prior art, this embodiment effectively reduces the influence of interference factors, improves the stability of the water injection amount of the ice-making box, and thus improves the ice-making effect.

[0090] This application also provides a refrigerator ice making control method based on the above refrigerator ice making system embodiment, referring to Figure 2 , Figure 2 This is a flow chart of the first embodiment of the refrigerator ice making control method of the present application.

[0091] In this embodiment, the refrigerator ice making control method includes steps S10 to S30:

[0092] Step S10: obtaining the current water inlet pressure of the water pipe through a water pressure sensor.

[0093] It should be noted that the executor of this embodiment is the controller described in the above refrigerator ice-making system embodiment. The controller can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device that can realize the above functions.

[0094] In a specific implementation, the above-mentioned water pressure sensor can detect the water pressure in the water pipe in real time, and convert the water pressure signal into an electrical signal and output it to the controller. The controller can obtain the current water inlet pressure of the water pipe based on the electrical signal.

[0095] Step S20: selecting a target water injection duration associated with the current water inlet pressure from a plurality of preset water injection durations.

[0096] In practice, during the development phase of a refrigerator's ice-making system, numerous water-injection experiments can be conducted, with pressure-time curves recorded at varying water inlet pressures to generate a standard pressure-time curve. In actual use, the controller can match the current water inlet pressure with the pre-stored standard pressure-time curve. Based on the matching results, the target water-injection time corresponding to the current water inlet pressure is determined.

[0097] Step S30: Filling the ice box with water by controlling the water inlet valve to open within the target water filling time.

[0098] It should be noted that after obtaining the target water filling time, the controller can control the water inlet valve based on the target water filling time. Specifically, the controller can control the water inlet valve to remain open during the target water filling time, so that water is continuously delivered from the water supply source to the ice making box during the target water filling time.

[0099] This embodiment uses a water pressure sensor to obtain the current water inlet pressure of the water pipe, selects a target water filling time associated with the current water inlet pressure from multiple preset water filling time periods, and controls the water inlet valve to open within the target water filling time period to fill the ice box with water. The water filling time period of the ice box in this application is selected based on the current water inlet pressure of the water pipe, achieving dynamic adjustment of the ice box filling time according to the actual water inlet pressure. Compared with the fixed time water filling method of the prior art, this embodiment effectively reduces the influence of interference factors, improves the stability of the water filling amount of the ice box, and thus improves the ice making effect.

[0100] Based on the first embodiment of the refrigerator ice making control method of the present application, the second embodiment of the refrigerator ice making control method of the present application is proposed. In the second embodiment of the refrigerator ice making control method of the present application, the same or similar contents as those of the first embodiment of the refrigerator ice making control method can be referred to the above introduction and will not be repeated hereafter. Figure 3 , Figure 3 This is a flow chart of the second embodiment of the refrigerator ice-making control method of the present application.

[0101] In this embodiment, step S20 includes steps S201 to S203:

[0102] Step S201: determining the target pressure range of the current water inlet pressure.

[0103] In a specific implementation, the water inlet pressure can be pre-divided into multiple fuzzy sets, each consisting of a different voltage range. Different fuzzy sets represent different voltage levels, such as "low pressure," "medium-low pressure," "medium pressure," "medium-high pressure," and "high pressure." A membership function is defined for each fuzzy set, using, for example, a triangular membership function or a trapezoidal membership function. The controller calculates the membership of the current water inlet pressure value to each fuzzy set and selects the range corresponding to the fuzzy set with the largest membership as the target pressure range for the current water inlet pressure.

[0104] In addition to the above-mentioned method, a feasible implementation method is proposed, in which step S201 includes steps S2011 to S2013:

[0105] Step S2011, obtaining multiple preset pressure ranges.

[0106] It should be noted that the above-mentioned preset pressure range can be a pre-established voltage range. For example, the following reference voltages exist from largest to smallest: P1, P2, P3, P4. The corresponding preset pressure ranges formed can be: P1 ≥ P, P1 > P ≥ P2, P2 > P ≥ P3, P3 > P ≥ P4, P4 > P, where P is any water inlet pressure.

[0107] Step S2012: Match the current water inlet pressure with each of the preset pressure ranges.

[0108] Step S2013: Using the successfully matched preset pressure range as the target pressure range of the current water inlet pressure.

[0109] In a specific implementation, the controller may traverse each preset pressure range, match the current water inlet pressure with each preset pressure range, and use the successfully matched preset pressure range as the target pressure range for the current water inlet pressure.

[0110] Step S202: obtaining a preset mapping relationship, wherein the preset mapping relationship represents a corresponding relationship between a preset pressure range and a water injection duration.

[0111] In a specific implementation, corresponding water injection times can be configured in advance for different preset pressure ranges to construct the above-mentioned preset mapping relationship, and pressure thresholds representing insufficient water pressure can also be configured. For example, P1≥P configures water injection time t1, P1>P≥P2 configures water injection time t2, P2>P≥P3 configures water injection time t3, and P3>P≥P4 configures water injection time t4. Among them, P4>P can represent insufficient water pressure, triggering a water shortage alarm, and the controller can control the water inlet valve to close.

[0112] Step S203 : selecting a target water injection duration associated with the target pressure range from a plurality of preset water injection durations through the preset mapping relationship.

[0113] In a specific implementation, the controller may query the water injection duration corresponding to the target pressure range from a preset mapping relationship as the target water injection duration.

[0114] This embodiment determines the target pressure range of the current water inlet pressure; obtains a preset mapping relationship, which represents the correspondence between the preset pressure range and the water filling time; selects the target water filling time associated with the target pressure range from multiple preset water filling time periods through the preset mapping relationship, thereby effectively improving the determination accuracy of the target water filling time, and further improving the water filling accuracy of the ice making box.

[0115] Based on the first and second embodiments of the refrigerator ice-making control method of the present application, the third embodiment of the refrigerator ice-making control method of the present application is proposed. In the third embodiment of the refrigerator ice-making control method of the present application, the same or similar contents as those in the first and second embodiments of the refrigerator ice-making control method can be referred to the above introduction and will not be repeated hereafter. Figure 4 , Figure 4 This is a flow chart of the third embodiment of the refrigerator ice-making control method of the present application.

[0116] In this embodiment, step S30 further includes steps S40 to S60:

[0117] Step S40 : When the current water filling time of the ice making box reaches the target water filling time, the water inlet valve is controlled to close, and water filling into the ice making box is stopped.

[0118] In a specific implementation, when the controller detects that the current water filling time reaches the target water filling time, it can control the water inlet valve to close, thereby cutting off the passage between the water supply source and the ice making box and stopping water filling into the ice making box.

[0119] Step S50: When the closing time of the water inlet valve reaches a preset closing time, the current ice box temperature of the ice box is obtained through a temperature sensor.

[0120] In a specific implementation, the controller can communicate with a temperature sensor. Once the ice box is filled with water (i.e., the water inlet valve is closed), the ice box enters a cooling phase. Cold air from the refrigerator's refrigeration system circulates through the refrigeration pipes, gradually lowering the temperature of the ice box. The ice box's temperature sensor monitors temperature changes in real time and feeds this data back to the controller, which then determines the current ice box temperature based on this data.

[0121] Step S60: Controlling the ice-making box to make ice according to the current temperature of the ice-making box.

[0122] It should be noted that when the water level is normal, the water in the ice box needs to absorb enough cold air during the cooling process to lower its temperature to the low temperature required for ice making. At this point, the temperature detected by the temperature sensor changes relatively smoothly, ultimately reaching a temperature range corresponding to a normal water level. When the water level is insufficient, the water's ability to absorb cold air is relatively weak due to the small amount of water. The water in the ice box reaches a lower temperature in a shorter period of time, causing the current ice box temperature detected by the temperature sensor to be low. This indicates that the water level in the ice box is insufficient for ice making and requires additional water to ensure the size and quality of the ice cubes.

[0123] Based on this, the controller can control the ice-making process of the ice-making box according to the current temperature of the ice-making box.

[0124] In a feasible implementation, step S60 includes steps S601 to S604:

[0125] Step S601: determining whether the current temperature of the ice making box reaches a preset temperature threshold.

[0126] Step S602: When the current temperature of the ice making box does not reach a preset temperature threshold, the water inlet valve is controlled to open.

[0127] Step S603: When the opening time of the water inlet valve reaches a preset opening time, the water inlet valve is controlled to be closed, so that the ice making box starts making ice.

[0128] Step S604: When the current temperature of the ice-making box reaches a preset temperature threshold, the water inlet valve is kept closed so that the ice-making box starts making ice.

[0129] In a specific implementation, the controller may compare the current ice box temperature with a preset temperature threshold to determine whether the current ice box temperature has reached the preset temperature threshold. If the current ice box temperature has not reached the preset temperature threshold, the controller may determine that the current ice box temperature is low, and further determine that the amount of water in the ice box does not meet ice making requirements. In this case, the controller may control the water inlet valve to open for a preset opening duration, and continue to fill the ice box with water during the preset opening duration to replenish the ice box and ensure the size and quality of the ice cubes. When the water inlet valve opening duration reaches the preset opening duration, the controller may control the water inlet valve to close, causing the ice box to begin making ice. When the current ice box temperature reaches the preset temperature threshold, the controller may determine that the amount of water in the ice box meets ice making requirements, and control the water inlet valve to remain closed, causing the ice box to begin making ice.

[0130] This embodiment controls the water inlet valve to close and stop filling the ice box when the current water filling time of the ice box reaches the target water filling time; obtains the current ice box temperature of the ice box through a temperature sensor when the water inlet valve closure time reaches a preset closure time; controls the water inlet valve to open when the current ice box temperature does not reach a preset temperature threshold; controls the water inlet valve to close when the water inlet valve opening time reaches a preset opening time to start ice making in the ice box; and maintains the water inlet valve closed when the current ice box temperature reaches a preset temperature threshold to start ice making in the ice box. By determining the temperature of the ice box after water filling is completed and controlling the ice making process of the ice box, sufficient water in the ice box is ensured, thereby guaranteeing the size and quality of the ice cubes.
