[0016] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0017] In recent years, as users' demand for frozen drinks continues to grow, the demand for ice-making equipment has also continued to grow, and the ice-making efficiency and energy consumption of ice-making equipment have attracted much attention.

[0018] The water temperature during ice making has a significant impact on the ice making capacity of the ice making equipment: when the water temperature is high, the ice making capacity will be significantly reduced under the same ice making time. When the demand for ice making is high, which is often when the temperature is high, the water temperature is usually high at room temperature, resulting in lower ice making efficiency.

[0019] In order to improve the above-mentioned problems, the inventors have proposed the pre-cooling control method, device, ice-making equipment and storage medium provided in the present application. The method is applied to the ice-making equipment, which includes a refrigeration system and a water supply system; the water supply system includes a water storage module, a water supply pipeline, a return water channel, a drive module and a water storage module; the method includes: when a pre-cooling instruction is received, obtaining the detected temperature of the liquid in the water storage module; if the detected temperature is greater than the pre-cooling control temperature, starting the refrigeration system to cool the water storage module, and starting the drive module to transport the liquid in the water storage module to the water storage module through the water supply pipeline; wherein, when the liquid level of the water storage module exceeds a preset liquid level, the liquid exceeding the preset liquid level flows back to the water storage module through the return water channel to reduce the temperature of the liquid in the water storage module, thereby eliminating the need to change the hardware architecture of the ice-making equipment and utilizing the synergistic effect of the ice-making system and the water supply system of the ice-making equipment to achieve high-efficiency and low-cost liquid pre-cooling, thereby effectively improving the ice-making efficiency of the ice-making equipment.

[0020] The following introduces the application environment of the pre-cooling control method provided by the present invention.

[0021] See also Figure 1 , Figure 1 This is a schematic diagram of an application scenario of a pre-cooling control method provided by an embodiment of the present invention. Figure 1 As shown, the ice-making device 100 includes a water supply system 110 and a refrigeration system 120 .

[0022] The water supply system 110 includes a water storage module 111 , a water supply pipeline 112 , a return water channel (not shown), a driving module 113 and a water storage module 114 .

[0023] The water storage module 111 is used to store liquid for ice making, such as purified water.

[0024] One end of the water supply pipe 112 is connected to the water inlet of the water storage module 114 , and the other end of the water supply pipe 112 is connected to the water storage module 111 .

[0025] The water outlet of the water storage module 114 is connected to one end of the water return channel, and the other end of the water return channel is connected to the water storage module 111. The water inlet of the water storage module 114 is closer to the bottom of the water storage module 114 than the water outlet.

[0026] When the driving module 113 is activated, the liquid in the water storage module 111 can be transported to the water storage module 114 through the water supply pipe 112, causing the liquid level in the water storage module 114 to rise. When the liquid level in the water storage module 114 reaches a preset level (i.e., reaches the water outlet), the liquid exceeding the preset level will flow back from the water outlet to the water storage module 111. The driving module 113 can be a water pump.

[0027] In some embodiments, a return channel connecting the water outlet and the water storage module 114 may be separately provided to allow liquid exceeding a preset liquid level to flow back from the return channel to the water storage module 111 through the water outlet.

[0028] In other embodiments, the ice-making device 100 further includes an ice basket for placing the prepared ice cubes. A water leakage hole is provided at the bottom of the ice basket. After the water holding module 114 completes ice making and ice removal, the ice cubes fall into the ice basket, and the excess liquid flows back to the water storage module 111 through the water leakage hole. In order to simplify the device structure and reduce the cost of device manufacturing, the return water channel can also reuse the ice drop channel for ice cubes to recover liquid that exceeds the liquid level. Specifically, the liquid level of the water holding module 114 rises. When the water holding module 114 is full, the liquid overflows, and the overflowed liquid falls into the ice basket, and flows back to the water storage module 111 through the water leakage hole at the bottom of the ice basket.

[0029] The refrigeration system 120 includes a compressor 121 , a condenser (not shown), a capillary tube, a fan 122 , and an ice-making evaporator 123 ; wherein the compressor 121 , the condenser, the capillary tube, and the ice-making evaporator 123 are connected in sequence.

[0030] When the fan 122 is started, it can dissipate heat for the condenser.

[0031] When the compressor 121 is started, high-temperature and high-pressure refrigerant vapor enters the condenser and is condensed into a refrigerant liquid at room temperature and high pressure in the condenser; the refrigerant liquid at room temperature and high pressure is throttled by the capillary tube to become a two-phase refrigerant mixture at low temperature and low pressure; the two-phase refrigerant mixture at low temperature and low pressure absorbs heat in the ice-making evaporator 123 (that is, it absorbs heat from the water holding module 114, causing the temperature of the liquid in the water holding module 114 to drop), thereby evaporating into low-temperature refrigerant vapor.

[0032] When the ice-making device 100 makes ice, the refrigeration system 120 cools the liquid in the water holding module 114. When the liquid in the water holding module 114 forms ice cubes, the ice cubes in the water holding module 114 can be discharged by adjusting the spatial orientation of the water holding module 114 (for example, flipping a preset angle) for the next round of ice making.

[0033] It should be noted that Figure 1 This is only an exemplary application scenario. The method provided in the embodiments of the present application can also be run in other application scenarios and is not limited here.

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0035] See also Figure 2 , an embodiment of the present application provides a pre-cooling control method, which is applied to the above-mentioned ice-making equipment.

[0036] Among them, the ice-making equipment includes a refrigeration system and a water supply system; the water supply system includes a water storage module, a water supply pipeline, a return water channel, a drive module and a water storage module, and the details can be referred to the detailed description of the above embodiment.

[0037] like Figure 2 As shown, the pre-cooling control method provided in the embodiment of the present application includes: step S210 to step S220.

[0038] Step S210: When a pre-cooling instruction is received, the temperature of the liquid in the water storage module is obtained as the detection temperature.

[0039] In some embodiments, the ice-making device is provided with a pre-cooling mode, and the user can generate a pre-cooling instruction through the interactive module (voice module, button module, touch screen module, etc.) of the ice-making device to trigger the pre-cooling mode through the pre-cooling instruction.

[0040] In some embodiments, the user may trigger the pre-cooling mode through the terminal, that is, send a pre-cooling instruction to the ice-making device through the terminal to trigger the pre-cooling mode.

[0041] In some embodiments, after the user starts ice making, the machine automatically enters the pre-cooling mode first.

[0042] The user can add liquid for making ice into the water storage module in advance.

[0043] In some embodiments, the ice-making device may include a temperature detection module, which is disposed in the water storage module and is used to detect the temperature of the liquid in the water storage module.

[0044] The temperature of the liquid in the water storage module has a great influence on the ice making efficiency. If the ice making demand is not met, the ice making time can be shortened and the ice making amount can be increased by lowering the temperature of the liquid in the water storage module.

[0045] When the ice-making device receives a pre-cooling command, it obtains the temperature of the liquid in the water storage module as detected by the temperature detection module. The detected temperature is the temperature of the liquid in the water storage module at the start of the pre-cooling mode. The subsequent pre-cooling process is controlled based on the detected temperature, thereby reducing the temperature of the liquid in the water storage module to the low temperature required for ice making.

[0046] Step S220: If the detected temperature is greater than the pre-cooling control temperature, the refrigeration system is started to cool the water storage module, and the driving module is started to transport the liquid in the water storage module to the water storage module through the water supply pipeline; wherein, when the liquid level of the water storage module exceeds the preset liquid level, it flows back to the water storage module through the return water channel to reduce the temperature of the liquid in the water storage module.

[0047] In some embodiments, the pre-cooling control temperature is the pre-cooling control temperature of the liquid during ice making, which can be 2-4°C, for example, 3°C.

[0048] If the detected temperature is greater than the pre-cooling control temperature, it means that the liquid temperature does not meet the requirements of efficient ice making, and the liquid in the water module needs to be cooled.

[0049] In an embodiment of the present application, the water storage module is cooled by starting the refrigeration system, and the driving module is started to transport the liquid in the water storage module to the water storage module through the water supply pipeline.

[0050] As the liquid passes through the water storage module, it exchanges heat with the module. As the refrigeration system continuously cools the module, it continuously removes heat from the liquid in the module. The driver module continuously transfers liquid from the water storage module to the water storage module, causing the liquid level in the module to rise. When the liquid level exceeds a preset level, it flows back to the water storage module through the return channel. The overflowing liquid, having been cooled, continues to exchange heat with the liquid in the water storage module, thereby lowering the temperature of the liquid in the water storage module.

[0051] In an embodiment of the present application, the refrigeration system is an ice-making device originally used to cool the water holding module and make ice. The pre-cooling control method provided in the embodiment of the present application cools the liquid in the water holding module by reusing the ice-making system and the water supply system of the ice-making device without changing the original hardware architecture of the ice-making device. The synergistic effect of the ice-making system and the water supply system of the ice-making device is utilized to achieve high-efficiency and low-cost liquid pre-cooling, thereby effectively improving the ice-making efficiency of the ice-making device.

[0052] In some embodiments, the steps of activating the refrigeration system and activating the driver module can be performed in parallel. Since the refrigeration system requires a certain amount of time to cool, in some embodiments, the refrigeration system can be activated for a preset time before activating the driver module to ensure that the liquid is efficiently cooled when passing through the water storage module.

[0053] In some embodiments, the pre-cooling control method provided in the embodiments of the present application further includes: if the temperature of the liquid is less than or equal to the pre-cooling control temperature, performing a de-icing operation.

[0054] During the pre-cooling process, the liquid temperature is continuously monitored. If the detected liquid temperature is less than or equal to the pre-cooling control temperature, the liquid in the water storage module has reached the required efficient cooling. During the pre-cooling process, as the refrigeration system continues to cool, the liquid in contact with the evaporator and the water storage module gradually freezes. This ice layer affects the normal ice making process, resulting in uneven ice shape during normal ice making. The presence of the ice layer can also cause significant errors in the calculation of the ice making time.

[0055] In order not to affect normal ice making, in an embodiment of the present application, if the temperature of the liquid is detected to be less than or equal to the pre-cooling control temperature, the ice-defrosting operation is performed.

[0056] The deicing operation refers to the removal of ice from the evaporator of a refrigeration system. In some embodiments, the deicing operation can be performed by switching the refrigerant flow direction, allowing high-temperature, high-pressure gaseous refrigerant to flow into the evaporator, releasing heat and thereby melting the ice. In other embodiments, a heating module can be installed inside or outside the steam generator to heat the evaporator to melt the ice. It is understood that this application is not limited to this embodiment, and the deicing operation can also be performed by other methods.

[0057] In some embodiments, after removing the ice layer from the evaporator of the refrigeration system, the de-icing operation may also include draining the liquid from the water storage module. For example, the spatial orientation of the water storage module can be adjusted to drain the liquid. Exemplarily, the water storage module is flipped at a predetermined angle to drain the liquid. The de-iced liquid is then returned to the water storage module, fully utilizing the liquid containing the ice layer to cool the liquid in the water storage module.

[0058] In some embodiments, the pre-cooling control method provided in the embodiment of the present application further includes: if the temperature of the liquid is less than or equal to the pre-cooling control temperature, controlling the refrigeration system and the driving module to stop working.

[0059] During the pre-cooling process, the temperature of the liquid is continuously detected. If the temperature of the liquid is detected to be less than or equal to the pre-cooling control temperature, it means that the liquid in the water storage module meets the high-efficiency cooling requirements. At this time, the refrigeration system and the drive module are controlled to stop working.

[0060] In some embodiments, the steps of stopping the refrigeration system and stopping the driver module can be performed in parallel. In some embodiments, after the refrigeration system stops, the temperature of the water storage module is still relatively low. Therefore, the refrigeration system can be stopped first, followed by the driver module. This allows the driver module to continue operating for a period of time after the refrigeration system stops, allowing the lower temperature of the water storage module to be fully utilized to cool the water storage module.

[0061] When the temperature of the water storage module is lowered to the pre-cooling control temperature or below the pre-cooling control temperature, if the user does not start the ice making mode, the ice making device will enter the insulation mode to maintain the temperature of the liquid in the water storage module within the preset insulation range.

[0062] In some embodiments, after the step of controlling the refrigeration system and the drive module to stop working if the temperature of the liquid is less than or equal to the pre-cooling control temperature, the pre-cooling control method provided in the embodiment of the present application further includes: starting the refrigeration system and the drive module if the temperature of the liquid is greater than the insulation control temperature; wherein the insulation control temperature is greater than the pre-cooling control temperature.

[0063] After the refrigeration system stops working, the temperature of the liquid in the water storage module will gradually rise. The ice-making equipment will continue to detect the temperature of the liquid in the water storage module. When it is detected that the temperature of the liquid is higher than the insulation control temperature, the refrigeration system and the drive module will be restarted to cool the liquid in the water storage module.

[0064] In some embodiments, the heat preservation control temperature is the upper limit temperature of the liquid in the heat preservation mode. The heat preservation control temperature can be 5-7°C, for example, 6°C.

[0065] In some embodiments, the ice-making device may also be provided with a cooling pipeline to provide another way to pre-cool the water storage module.

[0066] Among them, the cooling pipeline is connected to the refrigeration system, and the cooling pipeline is arranged in the water storage module, that is, the refrigeration circuit of the refrigeration system is extended to the water storage module. When the refrigeration system is started, the low-temperature and low-pressure refrigerant two-phase mixture will also flow into the cooling pipeline to cool the cooling pipeline. The cooling pipeline is arranged in the water storage module, and the cooling pipeline contacts the liquid in the water storage module for heat exchange, thereby achieving cooling of the liquid in the water storage module.

[0067] In some embodiments, if the detected temperature is greater than the pre-cooling control temperature, the refrigeration system is started to cool the water storage module, and the driving module is started to transport the liquid in the water storage module to the water storage module through the water supply pipeline, including: if the detected temperature is greater than the preset pre-cooling temperature, the refrigeration system is started to cool the water storage module and the cooling pipeline, and the driving module is started to transport the liquid in the water storage module to the water storage module through the water supply pipeline.

[0068] That is to say, during the pre-cooling process, the water storage module is pre-cooled through the dual paths of cooling in the cooling pipeline and cooling liquid return in the water storage module, which further improves the pre-cooling efficiency and improves the temperature resistance of the system.

[0069] During the ice-making process, the refrigeration system is turned on to make ice, and the residual cold of the ice-making system can be fully utilized by the cooling pipeline to suppress the rate of increase in the liquid temperature in the water storage module and further improve the ice-making efficiency.

[0070] During the pre-cooling process, when the liquid temperature reaches the pre-cooling control temperature, the ice-making equipment enters the insulation mode. In the insulation mode, the ice-making equipment continuously detects the temperature of the liquid. When the temperature of the liquid exceeds the control temperature range, the pre-cooling measures of the ice-making equipment are promptly started to control the temperature of the liquid.

[0071] In some embodiments, when the ice-making device has two pre-cooling modes, the corresponding pre-cooling mode can be selected according to the change in liquid temperature.

[0072] In some embodiments, the temperature change of the liquid, such as the rate of temperature change of the liquid, can be detected. When the rate of temperature change of the liquid is lower than a preset rate, the temperature of the liquid in the water storage module is controlled within a control temperature range by cooling the liquid through the cooling pipe. When the rate of temperature change of the liquid is higher than the preset rate, the temperature of the liquid in the water storage module is controlled within the control temperature range by both cooling the liquid through the cooling pipe and returning the cooled liquid to the water storage module.

[0073] In some embodiments, the temperature of the liquid can be detected, and the pre-cooling method to be used can be determined based on the temperature of the liquid. After the step of controlling the refrigeration system and the drive module to stop operating if the temperature of the liquid is less than or equal to the pre-cooling control temperature, the pre-cooling control method provided in the embodiment of the present application further includes the following steps.

[0074] (1) If the temperature of the liquid is greater than the insulation control temperature and less than the first temperature, the refrigeration system is started to cool the cooling pipe.

[0075] (2) If the temperature of the liquid is greater than the second temperature, the refrigeration system and the drive module are started.

[0076] Among them, the heat preservation control temperature is greater than the pre-cooling control temperature, the first temperature is greater than the heat preservation control temperature, and the second temperature is greater than the first temperature.

[0077] By adopting different cooling methods in stages, more efficient, energy-saving and stable temperature control can be achieved. This not only saves energy and reduces noise, extends the life of core equipment, but also ensures system stability and avoids system overload.

[0078] In different scenarios, when entering the pre-cooling mode, the initial temperature of the liquid in the water storage module is different. When the initial temperature of the liquid in the water storage module is close to the pre-cooling control temperature, the pre-cooling intensity required is smaller. When the initial temperature of the liquid in the water storage module is far from the pre-cooling control temperature, the pre-cooling intensity required is greater. In order to reduce the power consumption of the system and provide temperature control accuracy, in some embodiments, the step of starting the driving module to transport the liquid in the water storage module to the water holding module through the water supply pipeline may include the following steps.

[0079] (1) Determine the liquid flow rate based on the detected temperature.

[0080] (2) Start the driving module to transport the liquid in the water storage module to the water holding module through the water supply pipeline according to the liquid flow rate.

[0081] In some embodiments, multiple temperature intervals can be pre-set, each temperature interval having a corresponding flow rate, and the liquid flow rate is determined according to the temperature interval in which the detected temperature is located. The temperature interval closer to the pre-cooling control temperature corresponds to a lower liquid flow rate.

[0082] Exemplarily, three temperature intervals may be pre-set, such as a pre-cooling control temperature interval, a heat preservation control temperature interval, and a first temperature interval.

[0083] In some embodiments, when the detected temperature is within the pre-cooling control temperature range (T≤T1), the liquid flow rate is at a first flow rate. Optionally, T1 may be, for example, 10°C, and the first flow rate may be 10% of the flow rate.

[0084] In some embodiments, when the detected temperature is within the insulation control temperature range (T1<T≤T2), the liquid flow rate is at a second flow rate. Optionally, T2 may be, for example, 40°C, and the second flow rate may be 50% of the flow rate.

[0085] In other embodiments, when the detected temperature is within the insulation control temperature range, the liquid flow rate may also change linearly or exponentially according to the detected temperature to further refine the temperature control accuracy.

[0086] In some embodiments, when the detected temperature is within the first temperature interval (T2<T), the liquid flow rate is a third flow rate. Optionally, the third flow rate may be 100% flow rate.

[0088] The temperature detection module 310 is used to obtain the temperature of the liquid in the water storage module as the detection temperature when receiving the pre-cooling instruction.

[0089] The cooling control module 320 is used to start the refrigeration system to cool the water storage module if the temperature of the liquid is greater than the pre-cooling control temperature, and start the driving module to transport the liquid in the water storage module to the water storage module through the water supply pipeline; wherein, when the liquid level of the water storage module exceeds the preset liquid level, the liquid exceeding the preset liquid level flows back to the water storage module through the return water channel.
