[0002] In general ice-making equipment, the ice-water tank is a key component for storing cooling water, and is prone to breed bacteria due to the humid internal environment, large temperature fluctuation, and easy water residue, thereby affecting the water quality safety of the cooling water stored in the ice-water tank.

[0003] In order to ensure water quality safety, high-temperature sterilization is usually used to sterilize the ice-water tank and its pipeline. However, in actual application, the ice-water tank is limited by the ice-making function or affected by the residual water, and problems such as uneven temperature distribution and slow temperature rise often occur in the internal part of the ice-water tank, which leads to unstable sterilization effect and seriously affects the sterilization effect of the ice-water tank and its pipeline.

[0055] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0056] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms. These are used only to distinguish the first element from the second element. The terms "comprising" and "having," and any variations thereof, used in this application, are intended to cover non-exclusive inclusion. The term "multiple" used in this application refers to two or more. The term "and / or" used in this application refers to one of the embodiments, or any combination of multiple embodiments.

[0057] One embodiment of this application discloses a sterilization method for an ice-making system. The sterilization method for an ice-making system provided in this application embodiment can be applied to, for example... Figure 1 The ice-making system shown. (See attached image.) Figure 1 The ice-making system includes an ice-making module 110, an ice water tank 120, a heating module 130, a main water outlet 140, and a processor 150. A circulation control component 160 is installed on the circulation pipeline connecting the ice-making module 110 and the ice water tank 120. A water injection control component 131 is installed on the hot water pipeline connecting the heating module 130 and the ice water tank 120. A first drainage control component 132 is installed on the first drainage passage connecting the heating module 130 and the main water outlet 140. A second drainage passage connects the ice water tank 120 and the main water outlet 140. A second drainage control component 121 is provided on the passage; wherein, the heating module 130 is used to output heated water, and the processor 150 is connected to the water injection control component 131, the first drainage control component 132, the second drainage control component 121 and the circulation control component 160 respectively. The water injection control component 131, the first drainage control component 132 and the second drainage control component 121 are used to control the opening and closing of the hot water pipe, the first drainage passage and the second drainage passage respectively, and the circulation control component 160 is used to control the circulation of water in the ice water tank 120 and the ice making module 110.

[0058] Specifically, in response to the sterilization command, the processor 150 controls the second drainage control component 121 to open, thereby draining the water from the chilled water tank 120. The water in the chilled water tank 120 flows out through the second drainage passage to the main outlet 140, reducing the probability of residual water in the chilled water tank 120 contaminating subsequent water flowing into the chilled water tank 120, and reducing the negative impact of residual water on the heating efficiency and temperature distribution uniformity of the chilled water tank 120. The heating module 130 is used to output heated water.

[0059] When the water level parameter of the ice water tank 120 is less than or equal to the first preset water level threshold, the processor 150 controls the second drainage control component 121 to close and controls the water injection control component 131 to open, so that the water heated in the heating module 130 flows into the ice water tank 120 through the hot water pipe, so as to use the heated water to increase the water temperature of the ice water tank 120, so that the water temperature parameter in the ice water tank 120 meets the temperature conditions for high-temperature sterilization, thereby helping to improve the sterilization effect of the ice water tank 120.

[0060] When the water level parameter reaches the second preset water level threshold, the processor 150 controls the water injection control component 131 to close and controls the circulation control component 160 to open. Under the action of the circulation control component 160, the water in the ice water tank 120 circulates through the circulation pipeline in the ice water tank 120 and the ice making module 110, which improves the uniformity of temperature distribution of the water circulating in the ice water tank 120, the ice making module 110 and the circulation path, which helps to improve the sterilization effect and reduce sterilization dead zones.

[0061] In some embodiments, the ice-making system further includes a water level monitoring component (not shown in the figure) and an ice water tank temperature sensor (not shown in the figure). The water level monitoring component and the ice water tank temperature sensor are both located inside the ice water tank 120 and connected to the processor 150. They are used to monitor the water level parameters and water temperature parameters of the water in the ice water tank 120, respectively, and transmit the water level parameters and water temperature parameters to the processor 150 so that the processor 150 can monitor the water level and temperature of the water in the ice water tank 120.

[0062] In some embodiments, the water injection control component 131 includes a solenoid valve switch connected to a processor 150, which controls the on / off state of the solenoid valve switch. When the solenoid valve switch is turned on, water in the heating module 130 can flow into the ice water tank 120 through the hot water pipe, which helps to control the on / off state of the hot water pipe and thus helps to adjust the water level of the hot water added to the ice water tank 120.

[0063] In some embodiments, the first drainage control component 132 includes a solenoid valve switch connected to the processor 150, which controls the on / off state of the solenoid valve switch. When the solenoid valve switch is turned on, water in the heating module 130 can flow through the first drainage passage to the main outlet 140 and be discharged from the main outlet 140 outside the ice-making system. This facilitates control of the on / off state of the first drainage passage, thereby helping to drain excess water from the heating module 130.

[0064] In some embodiments, the ice-making system further includes a main outlet temperature sensor (not shown in the figure), which is disposed inside the passage near the main outlet 140 in the first drainage passage and connected to the processor 150. The main outlet temperature sensor is used to monitor the temperature of the hot water output from the heating module 130 when it flows to the main outlet 140, and to transmit the temperature parameters of the hot water to the processor 150 so that the processor 150 can monitor the temperature of the hot water in the heating module 130.

[0065] In some embodiments, the circulation control component 160 includes a solenoid valve switch and a water pump, both of which are connected to a processor 150. The processor 150 controls the on / off state of the solenoid valve switch and the water pump, respectively. When the solenoid valve switch is turned on, the water pump is activated. Under the action of the water pump, the water in the ice water tank 120 circulates through the circulation pipes in the ice water tank 120 and the internal pipes of the ice-making module 110. This utilizes the flushing action of the water flow to clean the circulation pipes, the inner wall of the ice water tank 120, and the internal pipes of the ice-making module 110, thereby helping to improve the high-temperature sterilization effect.

[0066] See Figure 2 In some embodiments, the water injection control component and the first drainage control component in the ice-making system can be replaced by a hot water switch control component 210. The hot water switch control component 210 is disposed on the hot water pipe and the first drainage passage. That is, the inlet of the hot water switch control component 210 is connected to the heating module 130 through one side of the hot water pipe, the first outlet of the hot water switch control component 210 is connected to the ice water tank 120 through the other side of the hot water pipe, and the second outlet of the hot water switch control component 210 is connected to the main outlet 140 through the first drainage passage and connected to the processor 150, for controlling the on / off of the hot water pipe and the first drainage passage respectively, so as to simplify the water flow path between the heating module 130, the ice water tank 120 and the main outlet 140, optimize the system structure, and thus help reduce equipment costs.

[0067] Specifically, when the processor 150 controls the hot water switch control component 210 to switch to the water filling state, the inlet and the first outlet of the hot water switch control component 210 are connected, and the hot water in the heating module 130 flows into the ice water tank 120 through the hot water pipe; when the processor 150 controls the hot water switch control component 210 to switch to the drainage state, the inlet and the second outlet of the hot water switch control component 210 are connected, and the hot water in the heating module 130 flows out of the main outlet 140 through the first drainage passage; when the processor 150 controls the hot water switch control component 210 to switch to the off state, both the first and second outlets of the hot water switch control component 210 are closed, and the hot water in the heating module 130 is stored inside the heating module 130. Using the hot water switch control component 210 to control the on / off of the hot water pipe and the first drainage passage respectively helps simplify the control logic of the ice-making system, improves the response speed of the hot water switch control component 210, and reduces system complexity.

[0068] See Figure 3 Based on the above hardware structure, in an exemplary embodiment, a sterilization method for an ice-making system is provided, which is applied to... Figure 1 Taking processor 150 as an example, the explanation includes steps 302 to 308. Wherein:

[0069] Step 302: In response to the sterilization command, control the second drainage control component to open, so as to drain the water in the ice water tank.

[0070] Among them, the sterilization command is the sterilization command issued by the operator to the processor.

[0071] In this embodiment, in response to the sterilization command, the processor controls the second drainage control component to open, so that the residual water in the ice water tank flows to the main outlet through the second drainage passage to discharge the water in the ice water tank and reduce the negative impact of residual water on the high-temperature sterilization effect.

[0072] It should be noted that, ideally, the water in the ice water tank can be completely drained. However, in some embodiments, if a very small amount of water remains in the ice water tank after drainage, it can be considered that the ice water tank has been emptied, in order to shorten the drainage time and improve drainage efficiency.

[0073] Step 304: Obtain the water level parameters of the ice water tank.

[0074] Among them, the water level parameter refers to the height of the residual water level in the ice water tank within the ice water tank.

[0075] Step 306: When the water level parameter is less than or equal to the first preset water level threshold, control the second drainage control component to close and control the water injection control component to open, so that the water heated in the heating module flows into the ice water tank through the hot water pipe.

[0076] The first preset water level threshold refers to the water level value of the water remaining in the ice water tank after the water in the ice water tank has been emptied to the maximum extent.

[0077] In this embodiment, the processor dynamically adjusts the first preset water level threshold according to the water level parameters of the ice water tank and the flow rate of the water flowing out of the main outlet, so as to shorten the drainage time, improve drainage efficiency, and reduce resource waste while emptying the residual water in the ice water tank as much as possible.

[0078] Step 308: When the water level parameter reaches the second preset water level threshold, the water injection control component is turned off and the circulation control component is turned on; under the action of the circulation control component, the water in the ice water tank circulates between the ice water tank and the ice making module through the circulation pipeline.

[0079] The second preset water level threshold refers to the minimum water level in the ice water tank that allows the hot water to reach the high-temperature sterilization condition.

[0080] In this embodiment, the processor sets a reasonable second preset water level threshold based on the total capacity of the ice water tank to improve the sterilization effect. In other embodiments of this application, the processor can also comprehensively adjust the second preset water level threshold based on parameters such as the total capacity of the ice water tank, the temperature of the water in the ice water tank, and the total volume of the water in the ice water tank to improve the sterilization effect.

[0081] The sterilization method of the aforementioned ice-making system, by responding to a sterilization command and controlling the second drainage control component to open, drains water from the ice water tank, reducing the impact of residual water in the ice water tank on the sterilization effect; by adding heated water to the ice water tank through the heating module, the water level parameter of the ice water tank reaches the preset second water level threshold, ensuring that the total heat of the water in the ice water tank reaches the minimum total heat required for sterilization after entering the sterilization mode, reducing the probability that the required sterilization temperature cannot be reached due to heat loss and water temperature drop during the sterilization process; by controlling the circulation control component to open, the water in the ice water tank circulates through the circulation pipe in the ice water tank and the ice-making module, improving the uniformity of water temperature distribution in the ice water tank, circulation pipe, and ice-making module, which helps to further improve the sterilization effect and reduce sterilization dead zones.

[0082] See Figure 4 In some embodiments, step 306 includes steps 402 to 408.

[0083] Step 402: When the water level parameter is less than or equal to the first preset water level threshold, the water temperature parameter in the ice water tank is obtained in real time.

[0084] The water temperature parameter refers to the temperature of the water in the ice water tank, and the range of the water temperature parameter includes 0℃-100℃.

[0085] In this embodiment, the processor determines whether the water in the ice water tank has been drained based on the acquired water level parameters. Next, the processor acquires the water temperature parameters in the ice water tank in real time, so as to select an appropriate preheating method to preheat the ice water tank based on the water temperature parameters, reducing the temperature difference between the ice water tank and the subsequently injected water, thereby improving the sterilization effect.

[0086] Step 404: When the water temperature parameter reaches the first preset temperature threshold, control the first drainage control component to open so that the water heated in the heating module is discharged through the main outlet.

[0087] The first preset temperature threshold refers to the lowest temperature that the water in the ice water tank can reach without affecting the sterilization effect.

[0088] In this embodiment, the processor can comprehensively adjust the first preset temperature threshold based on parameters such as the total capacity of the ice water tank, the temperature of the water in the ice water tank, and the total volume of the water in the ice water tank, so as to improve the sterilization effect.

[0089] Step 406: Obtain the water temperature parameters of the water discharged from the main outlet in real time.

[0090] The outlet water temperature parameter is the actual temperature of the water heated by the heating module when it flows through the first drainage channel to the main outlet.

[0091] In this embodiment, after the processor controls the first drainage control component to turn on, the heating module heats the water and outputs the heated water. The processor obtains the water temperature parameters of the water flowing to the main outlet to reduce the probability of relatively low-temperature water flowing directly into the ice water tank, which helps to increase the temperature of the water flowing into the ice water tank, thereby helping to improve the sterilization effect.

[0092] Step 408: When the outlet water temperature parameter reaches the second preset temperature threshold, control the first drainage control component to close and control the water injection control component to open.

[0093] The second preset temperature threshold refers to the lowest temperature at which bacteria or other microorganisms in the internal pipes of the ice water tank, circulation pipes, and ice-making module are unlikely to survive.

[0094] In this embodiment, the processor controls the first drainage control component to close and controls the water injection control component to open, so that the heated water in the heating module flows into the ice water tank to improve the high-temperature sterilization effect of the ice water tank.

[0095] See Figure 5 In one embodiment, step 402 includes steps 502 to 506.

[0096] Step 502: When the water temperature parameter is less than the first preset temperature threshold, enter the cycle preset mode; in the cycle preset mode, at the beginning of each preheating cycle, control the water injection control component to turn on and obtain the water level parameter of the ice water tank.

[0097] The cycle preset mode is used to perform periodic step-by-step preheating of the ice water tank, circulation pipeline and ice making module to reduce the temperature difference between the ice water tank and the subsequently injected hot water, thereby helping to improve the sterilization effect.

[0098] It should be noted that if the water temperature parameter is lower than the first preset temperature threshold, it indicates that the water temperature in the ice water tank is relatively low. In this case, if water heated by the heating module is directly injected into the ice water tank, there is a risk that the sterilization effect will be affected due to the large temperature difference between the hot water and the ice water tank. Therefore, in this embodiment, the processor controls the water injection control component to open at the beginning of the preheating cycle, so that the water in the heating module flows directly into the ice water tank before reaching the second preset temperature threshold. This reduces the temperature difference between the water flowing into the ice water tank and the water already in the ice water tank. At the same time, the water flowing into the ice water tank from the heating module helps to raise the water temperature in the ice water tank, which helps to achieve the first preheating process of the ice water tank.

[0099] Furthermore, after entering the cycle preset mode for a period of time, if the water temperature parameter of the ice water tank rises and reaches the first preset temperature threshold, the cycle preset mode will be exited. At this time, the temperature difference between the water temperature parameter of the ice water tank and the water heated by the heating module is relatively small, and the water heated by the heating module can be directly injected into the ice water tank for subsequent sterilization, thereby helping to improve the sterilization effect.

[0100] Step 504: When the water level parameter reaches the second preset water level threshold, control the water injection control component to close and control the circulation control component to open.

[0101] In this embodiment, when the water level parameter reaches the second preset water level threshold, it indicates that the water in the ice water tank is in a high liquid level state. This can also be understood as the hot water flowing into the ice water tank filling the tank, or the hot water level in the ice water tank reaching the maximum capacity of the ice water tank. At this time, the processor controls the water injection control component to close and controls the circulation control component to open. Under the action of the circulation control component, water circulates through the circulation pipes in the ice water tank and the ice-making module, realizing one preheating process for the ice water tank, the ice-making module, and the circulation pipes.

[0102] Step 506: When the opening duration of the circulation control component reaches a preset circulation duration threshold and / or the change in water temperature parameters reaches a first preset step temperature threshold, the circulation control component is controlled to close, and the second drainage control component is controlled to open.

[0103] The preset cycle duration threshold refers to the maximum duration of the current preheating cycle from the start time; the first preset step temperature threshold refers to the maximum temperature change of the water in the ice water tank during each preheating cycle. In this embodiment, the current preheating cycle can be terminated as long as at least one of the following conditions is met: "the on-time of the cycle control component reaches the preset cycle duration threshold" and "the change in water temperature parameters reaches the first preset step temperature threshold," thus representing the completion of a preheating process.

[0104] In this embodiment, under the cycle preset mode, the processor obtains the water temperature parameters of the ice water tank in real time to determine whether the current preheating cycle end condition is met, and whether the cycle preset mode exit condition is met.

[0105] In this process, the first heating temperature of the water output by the heating module in the current preheating cycle is greater than the second heating temperature of the water output by the heating module in the previous preheating cycle, and the difference between the first heating temperature and the second heating temperature is the second preset step temperature value.

[0106] It should be noted that the second preset step temperature value represents the change in water output from the heating module between two consecutive preheating cycles, while the first preset step temperature threshold represents the change in water temperature in the ice water tank between two consecutive preheating cycles. Since there is some heat loss during the flow of water from the heating module into the ice water tank through the hot water pipes, the first preset step temperature threshold is usually less than or equal to the second preset step temperature value.

[0107] In one embodiment, step 308 above includes the following steps:

[0108] If the water temperature parameter is greater than the third preset temperature threshold for a duration that reaches the first preset sterilization duration threshold, the circulation control component is turned off, and the second drainage control component is turned on to drain the water from the ice water tank.

[0109] The third preset temperature threshold refers to the lowest temperature value corresponding to the hot water reaching the sterilization condition; the first preset sterilization time threshold refers to the shortest sterilization time required to completely eliminate bacteria and microorganisms or at least eliminate most bacteria and microorganisms.

[0110] In one embodiment, the second preset temperature threshold is greater than the third preset temperature threshold, and the third preset temperature threshold is greater than the first preset temperature threshold. This ensures that after the water heated by the heating module (at which point the water temperature parameter is greater than the second preset temperature threshold) flows through the hot water pipe and loses some heat, the remaining temperature of the water is still greater than the third preset temperature threshold, thus ensuring the effectiveness of the sterilization process.

[0111] In one embodiment, step 308 above includes the following steps:

[0112] When the operating time of the circulation control component reaches the second preset sterilization time threshold, the circulation control component is controlled to close, and the second drainage control component is controlled to open to drain the water in the ice water tank.

[0113] The second preset sterilization time threshold represents the time required for the sterilization rate in the ice water tank to reach the preset value.

[0114] It should be noted that when other sterilization methods are used during the sterilization process of the ice-making system, such as when the UV lamps in the ice-making system are turned on simultaneously while the circulation control component is running, the sterilization effect can be improved by extending the irradiation time of the UV lamps, even if the water temperature in the ice water tank is lower than the third preset temperature threshold.

[0115] In one embodiment, the second preset water level threshold is greater than the first preset water level threshold.
