Description

Technical Field

[0001] The present invention relates to the technical field of preventing ice connection in an ice bin of an ice maker, and particularly to a method, device, equipment and medium for preventing ice connection in an ice bin of an ice maker. Background Art

[0002] In the modern food and beverage industry, ice makers are widely used in various scenarios, including food service, bars, and food storage. The normal operation of ice makers is crucial for ensuring the quality of food and beverages. However, due to factors such as external environmental changes and equipment failures, the ice cubes in the ice maker may agglomerate, that is, the ice cubes stick together to form "connected ice", which directly affects the ice-making efficiency of the ice maker and the quality of the ice cubes.

[0003] The formation of connected ice is mainly closely related to the temperature control in the ice bin. When the temperature in the ice bin rises, the surface of the ice cubes will start to melt, and moisture will accumulate between the ice cubes, resulting in the ice cubes sticking to each other. In addition, long-term static placement will also exacerbate the phenomenon of connected ice. Currently, the prevention of connected ice is mainly achieved by agitation, but long-term agitation will affect the quality of the ice cubes. Therefore, there is an urgent need for a method for preventing connected ice to balance the agitation time. Summary of the Invention

Description of the Drawings

[0047] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention, and for those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0048] Among them:

[0049] Figure 1 It is an application environment diagram of the ice connection prevention method for the ice bin of the ice maker in an embodiment;

[0050] Figure 2 It is a flowchart of the ice connection prevention for the ice bin of the ice maker in an embodiment;

[0051] Figure 3 Structural block diagram of an ice - connecting prevention device for an ice storage bin of an ice maker in an embodiment;

[0052] Figure 4 Structural block diagram of a computer device in an embodiment. Detailed implementation manners

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0054] In a specific embodiment, the ice-making process of the ice maker is as follows. After the ice maker activates the ice-making function, the compressor starts working to make ice. After the first ice-making is completed, the ice cubes are pushed into the ice bin through the ice-turning and ice-shoveling structure. There is an ice-stirring worm and an ice-bin temperature NTC in the ice bin, and a supplementary cooling evaporator is arranged outside the ice bin. Since the supplementary cooling evaporator and the ice-making system are generally set in a series structure, the supplementary cooling evaporator also absorbs heat and cools during the first ice-making. When the first ice-making is in progress, the supplementary cooling evaporator absorbs heat to lower the temperature in the ice bin. When the ice cubes enter the ice bin, due to the lower temperature in the ice bin, the melting speed of the ice cubes can be effectively slowed down. After the first ice-making is completed, the compressor works again, and at this time, the supplementary cooling evaporator also works to lower the temperature in the ice bin and reduce the melting of the ice cubes in the ice bin. As the supplementary cooling of the ice bin progresses, the temperature in the ice bin continues to drop. When the temperature drops to a certain value, to ensure that the ice cubes in the ice bin do not connect due to too low a temperature, the ice-bin worm starts to rotate clockwise for 5 seconds and then counterclockwise for 5 seconds (or other times, which can be adjusted accordingly according to the temperature change situation) to stir and break up the ice cubes in the ice bin. When the ice bin is full of ice, the worm in the ice bin immediately rotates clockwise for 5 seconds and then counterclockwise for 5 seconds to stir and break up the ice in the ice bin. After the ice-making operation is completed, the ice maker enters the supplementary cooling and heat preservation state: when the ice-bin NTC detects that the temperature in the ice bin is lower than a certain value, the supplementary cooling evaporator on the outer wall of the ice bin does not work; as the temperature rises, the ice-bin worm starts to rotate accordingly to stir and break up the ice cubes to prevent the ice from connecting due to the melting of the ice cubes caused by the rising temperature; when the ice-bin NTC detects that the temperature in the ice bin is higher than a certain value, the supplementary cooling evaporator on the outer wall of the ice bin starts to work for supplementary cooling; as the temperature drops, the ice-bin worm starts to rotate to stir and break up the ice cubes to prevent the ice from connecting due to too rapid a temperature drop. The ice-bin worm is designed as an asymmetric spiral worm, that is, it has a positive lead angle and a negative lead angle: during ice discharging, due to the design of the positive lead angle, the contact between the worm and the ice cubes increases, making the ice discharging smoother; when stirring the ice to prevent ice connection problems, due to the design of the negative lead angle, the shear force is increased, making it easier for the ice cubes to be sheared and broken up when ice connection occurs. The surface of the ice-bin worm is treated to increase the contact area with the ice cubes, thereby increasing the friction force, making the ice discharging and ice stirring more effective.

[0055] Figure 1 It is an application environment diagram for preventing ice connection in the ice bin of an ice maker in an embodiment. Refer to Figure 1, The method for preventing ice bonding in the ice bin of an ice maker is applied to the ice bin ice bonding prevention system of the ice maker. The ice bin ice bonding prevention system of the ice maker includes a terminal 110 and a server 120. The terminal 110 and the server 120 are connected through a network. The terminal 110 can specifically be a desktop terminal or a mobile terminal, and the mobile terminal can specifically be at least one of a mobile phone, a tablet computer, a laptop computer, etc. The server 120 can be implemented by an independent server or a server cluster composed of multiple servers. The terminal 110 is used to monitor a preset temperature value, and the server 120 is used to provide data support.

[0056] As Figure 2 shown, in one embodiment, a method for preventing ice bonding in the ice bin of an ice maker is provided. This method can be applied to both the terminal and the server. In this embodiment, it is exemplified by being applied to the terminal. A temperature detection unit and a worm are arranged in the ice bin of the ice maker. The temperature detection unit is used to detect the temperature value in the ice bin of the ice maker, and the worm is used to stir the ice cubes in the ice bin of the ice maker. The method for preventing ice bonding in the ice bin of the ice maker specifically includes the following steps:

[0057] S1: Continuously monitor whether the temperature value in the ice bin of the ice maker is higher than the preset temperature value;

[0058] S2: When it is monitored that the temperature value at the current moment is higher than the preset temperature value, then based on the temperature sequence within a set time period before the current moment;

[0059] S3: Calculate the temperature change rate according to the temperature sequence;

[0060] S4: Set the stirring parameters of the worm based on the temperature change rate;

[0061] S5: Control the worm to stir the ice cubes in the ice bin of the ice maker based on the stirring parameters.

[0062] As described in step S1 above, continuously monitor whether the temperature value in the ice bin of the ice maker is higher than the preset temperature value. The ice maker continuously monitors the temperature value in the ice bin through the temperature detection unit. Since the ice making efficiency and the quality of the ice cubes are directly affected by the temperature, the preset temperature value is a standard formulated according to the design and working conditions of the device, that is, the temperature at which ice bonding is preset to occur. Specifically, it can be set manually according to the actual situation. When the monitored temperature value is higher than this standard, it indicates that the ice bin environment may have an ice bonding phenomenon. Through temperature monitoring, the ice maker can respond in a timely manner and initiate subsequent ice cube stirring and temperature adjustment measures, thereby preventing the ice bonding phenomenon of the ice cubes.

[0063] As described in step S2 above, when the temperature value at the current moment is higher than the preset temperature value, it is based on the temperature sequence within a set duration before the current moment. When the temperature value in the ice bin is detected to be higher than the preset temperature, the ice maker will analyze based on the temperature sequence within the set duration to determine subsequent agitation actions. Herein, the temperature sequence refers to the temperature data collected within a period of time before the current moment and can provide trend information on temperature changes.

[0064] As described in step S3 above, calculate the temperature change rate according to the temperature sequence. Calculating the temperature change rate means calculating the change speed of temperature over time, and through this change rate, the stability of the internal environment of the ice bin can be evaluated. Specifically, using the data in the temperature sequence, the device will calculate the temperature change situation within a certain time period according to the formula. Since the temperature change rate reflects the real-time temperature fluctuations, and the phenomenon of ice block adhesion generally occurs under the condition of easy temperature change, that is, when the temperature rises, the surface of the ice block will melt to form a water film, and the existence of the water film increases the contact area between the ice blocks. In this case, if the temperature drops rapidly, the water film may freeze quickly, resulting in the adhesion of ice blocks to form ice block adhesion. If the temperature change rate is relatively slow, the melting of the ice block surface and the loss of moisture will be relatively uniform, reducing the possibility of ice block adhesion. Therefore, it cannot be considered that ice block adhesion occurs when the temperature is lower than a certain value, but the change situation needs to be considered. If the temperature change situation, that is, the temperature change rate, is large during this period, it indicates that the temperature range in the ice bin of the ice maker is large and ice block adhesion is likely to occur. Therefore, the temperature change rate can provide strong data support for setting subsequent agitation parameters of the worm, so that appropriate agitation measures can be taken in a high-temperature environment to minimize the ice block adhesion phenomenon to the greatest extent.

[0065] As described in steps S4 - S5 above, set the agitation parameters of the worm based on the temperature change rate, and control the worm to agitate the ice blocks in the ice bin of the ice maker based on the agitation parameters. After obtaining the temperature change rate, the device will set the agitation parameters of the worm according to this value. Specifically, the way of setting the agitation parameters is not limited. For example, a relationship correspondence table between the temperature change rate and the agitation parameters can be established in advance, and then the agitation parameters can be set according to the relationship correspondence table. Or a calculation formula can be set in advance, and then the forward and reverse cycle is combined with the ideal temperature, the current temperature, and the temperature change rate to ensure that the agitation action of the worm can adapt to the state change of the ice blocks, such as the increase or decrease in the number of ice blocks. Through this dynamic adjustment, the ice maker can maintain an ideal operating environment while effectively preventing ice block adhesion and realizing efficient and intelligent ice bin management.

[0066] In one embodiment, step S3 of calculating the temperature change rate according to the temperature sequence includes:

[0067] S301: According to the formula Calculate the temperature change rate; where, ΔT represents the temperature change rate, and t i represents the i-th temperature value in the temperature sequence, and t i-1 represents the (i - 1)-th temperature value in the temperature sequence, and t j represents the j-th temperature value in the temperature sequence, and t j-1 represents the (j - 1)-th temperature value in the temperature sequence, and G(·) represents a pre-designed calculation function.

[0068] As described in the above step S301, the calculation of the temperature change rate is realized, where G(·) represents a pre-designed calculation function, which can specifically be a linear function, a quadratic function, an exponential function, a composite function, a logarithmic function, etc. The condition it needs to meet is that the higher the temperature value, the greater the corresponding function value. The greater the temperature change rate, it indicates that during this period, the temperature change amplitude in the ice bin of the ice maker is greater, which will cause ice cubes to stick together and form the phenomenon of connected ice.

[0069] In one embodiment, the step S4 of setting the stirring parameter of the worm based on the temperature change rate includes:

[0070] S401: Obtain the ideal temperature value of the ice bin of the ice maker and the number of ice cubes in the ice bin;

[0071] S402: According to the formula Δt = K p ·(T target - t1)+ K d ·ΔT to calculate the forward and reverse cycle of the worm, and set the stirring time of the worm according to the number of ice cubes, so as to set the stirring parameter of the worm; where, Δt is the forward and reverse cycle, and K p and K d are both constant parameters, T target is the ideal temperature value, t1 is the temperature value at the current moment, and ΔT is the temperature change rate.

[0072] As described in the above steps S401 - S402, the calculation of the agitation parameters is achieved. The ideal temperature value is usually preset according to the design parameters of the device and the actual operating conditions. Usually, for the ice cubes to be stored in the best state, ensuring that they do not melt and preventing quality loss at too low temperatures, this temperature is used as the ideal temperature value. At the same time, different numbers of ice cubes will affect the temperature distribution, cooling efficiency, and the operation mode of the ice maker. When the number of ice cubes is large, the interaction between the ice cubes will affect their temperature changes, possibly causing the surface temperature of some ice cubes to rise, making them more likely to melt and trigger ice bridging. Therefore, by accurately obtaining the number of ice cubes in the ice bin, the device can better evaluate the condition of the ice cubes and provide a basis for subsequent agitation and refrigeration measures. Specifically, the collection method can be carried out through the ice cube detection unit, which monitors the actual number of ice cubes in the ice bin through sensors. The ice maker will calculate the forward and reverse rotation periods of the worm using a preset formula based on the obtained ideal temperature value and the number of ice cubes in the ice bin. The forward and reverse rotation period refers to the duration of each rotation of the worm in one direction during the agitation process, and the time required to turn to the other direction afterwards. The calculation of this period is crucial for optimizing the agitation effect of the ice maker because a suitable agitation period can keep the ice cubes in a loose state and prevent them from sticking due to surface melting. Setting the agitation time of the worm according to the number of ice cubes further strengthens this control mechanism. When the number of ice cubes is large, a longer agitation time is required to ensure that each ice cube can be fully agitated and cooled; while when the number of ice cubes is small, a shorter agitation time is sufficient to maintain the quality of the ice cubes. Through the calculation of the formula, the ice maker can dynamically adjust the agitation parameters of the worm to ensure that the worm always works with the optimal efficiency under different numbers of ice cubes and ambient temperatures. This process not only improves the dispersion of the ice cubes, reduces the risk of ice bridging, but also enhances the overall working efficiency of the ice maker. Through a reasonable agitation strategy, the use of resources is optimized to ensure that the ice cubes are always in the best cooling state, where K p and K d The value ranges are not limited and can be adjusted according to the size of the ice bin of the ice maker, so that the final forward and reverse rotation period is between 5s - 30s. Among them, K d The value is generally 2 - 5 times that of K p In a household water dispenser, the value of K d is generally about 5.

[0073] In an embodiment, the ice bin of the ice maker further includes an ice cube detection unit for detecting the number of ice cubes in the ice bin of the ice maker. Before the step S1 of continuously monitoring whether the temperature value in the ice bin of the ice maker is higher than the preset temperature value, it further includes:

[0074] S001: Monitoring the number of ice cubes in the ice bin of the ice maker through the ice cube detection unit;

[0075] S002: Based on a preset correspondence table between the number of ice cubes and temperature values, set the preset temperature value according to the number of ice cubes.

[0076] As described in the above steps S001 - S002, the ice cube detection unit is used to monitor the number of ice cubes in the ice bin in real time. The ice cube detection unit usually consists of a sensor (such as an infrared sensor), and mechanical, optical, or ultrasonic sensing technologies can also be used to monitor the number of ice cubes in the ice bin. This enables timely understanding of the current storage status of the ice bin, ensuring that the device can be adjusted according to the actual situation at different operating stages. Since the change in the number of ice cubes directly affects the operation mode and working efficiency of the ice maker. For example, when the number of ice cubes increases, their contact area will be larger, and the relatively high contact temperature may cause melting water on the surface of the ice cubes, thus increasing the risk of ice block connection. Therefore, obtaining the information of the number of ice cubes in a timely manner can help the ice maker take corresponding stirring measures when the capacity reaches a certain threshold, preventing the ice cubes from being damaged or affected in use due to adhesion. At the same time, the monitoring of the number of ice cubes can also assist the ice maker in temperature adjustment, maintaining an ideal environment in the ice bin through dynamic adjustment. The preset temperature value is set according to the number of ice cubes, based on a predefined correspondence table between the number of ice cubes and temperature values. This table is usually obtained through experiments or calculations during the device design, providing appropriate temperature values for different numbers of ice cubes to ensure that the ice cubes are in the best storage and use state. When the number of ice cubes reaches a certain specific value, the corresponding temperature value will be set in real time to meet the best standard for the current ice bin situation. For example, if the number of ice cubes is large, the heat in the ice bin may cause the temperature to rise due to the stacking of ice cubes, and at this time, a lower preset temperature value needs to be set to maintain the cooling state of the ice cubes. On the contrary, if the number of ice cubes is small, the temperature value can be appropriately increased to reach a standard that can operate effectively without causing ice block connection. Through such dynamic adjustment, the ice maker can not only efficiently maintain an ideal storage environment, but also help reduce energy consumption and refrigeration burden, improving the overall operating efficiency.

[0077] In one embodiment, after the step S001 of monitoring the number of ice cubes in the ice bin of the ice maker by the ice cube detection unit, the following is further included:

[0078] S0021: When the number of ice cubes in the ice bin of the ice maker monitored by the ice cube detection unit changes from the unfilled state to the filled state, control the worm to stir with a first preset parameter.

[0079] As in the above step S0021, when the number of ice cubes changes from the unfilled state to the filled state, corresponding control is performed to ensure the quality of the ice cubes. By monitoring the change in the number of ice cubes, the ice maker can determine the filling state of the ice bin and decide the agitation behavior of the worm gear based on this judgment result. When the ice bin is in the filled state, it often means that the ice cubes need to be agitated more frequently to prevent the phenomenon of ice blockage caused by extrusion or too long time. In this case, the ice maker starts to agitate according to the set first preset parameter, prompting the ice cubes to remain loose in the bin, thus effectively preventing their adhesion and providing good ice cubes for subsequent use. Among them, the first preset parameter is short-cycle and low-intensity agitation to balance ice blockage prevention and ice cube quality. For example, "the first preset parameter is that the worm gear rotates forward for 10 seconds and reverses for 5 seconds, and the agitation cycle is 30 seconds.

[0080] In one embodiment, the ice bin of the ice maker further includes an outer wall supplementary cooling evaporator for cooling the ice cubes in the ice bin of the ice maker. After the step S1 of continuously monitoring whether the temperature value in the ice bin of the ice maker is higher than the preset temperature value, the following steps are further included:

[0081] S201: When the temperature value in the ice bin of the ice maker is lower than or equal to the preset temperature value, detect whether the outer wall supplementary cooling evaporator is in the rest state;

[0082] S202: If it is in the rest state, control the worm gear to agitate with a second preset parameter.

[0083] As described in the above steps S201 - S202, the ice maker first checks whether the temperature in the ice bin is lower than or equal to a preset temperature value. The preset temperature value is usually set according to the design standards and optimal operating conditions of the device, belonging to an ideal working range. When the temperature is lower than or equal to this value, it means that the current cooling effect of the device is good, the ice cubes are in a good storage state, and usually no additional cooling measures are required. Subsequently, the ice maker will detect the operating state of the outer wall supplementary cooling evaporator. The main function of the outer wall supplementary cooling evaporator is to enhance the cooling effect in the ice bin. By cooling the outer wall of the ice bin, the cooling efficiency of the ice cubes is further improved. If the evaporator is in a resting state, it means that the device is not performing the supplementary cooling work. This detection not only helps to judge the current operating condition but also helps to save energy and reduce unnecessary equipment wear. When implementing this detection, the ice maker usually uses a temperature sensor or a pressure sensor to determine whether the outer wall evaporator is in an active state. When it is detected that the outer wall supplementary cooling evaporator is indeed in a resting state, where the resting state is a pre - set state. In a specific embodiment, if the supplementary cooling evaporator has not started refrigeration for 30 consecutive minutes, it is determined to be in a resting state. The worm starts to agitate with a second preset parameter, ensuring the operation when the cooling effect does not necessarily need to be enhanced, so as to avoid burdening the device. Controlling the worm to agitate with a second preset parameter can effectively promote the mixing and spreading of the ice cubes. At the same time, it avoids the ice cubes being broken or damaged due to extremely high agitation intensity. The second preset parameter is usually a gentler agitation setting compared to the first preset parameter, aiming to keep the ice cubes in a loose state under the current conditions, prevent the occurrence of ice bridging, and ensure that the ice cubes maintain the optimal temperature. This gentle agitation of the worm helps to evenly distribute the temperature, making the crystallization state of the ice cubes stable during storage. It enables the ice maker to maintain the state of the ice cubes without the need to strengthen cooling, effectively preventing the risk of ice bridging. The whole process not only ensures the quality of the ice cubes but also reduces the energy consumption of the system. In addition, the dynamically adjusted agitation parameters ensure the adaptability of the entire ice maker system under different environments and loads, enabling it to work efficiently and safely.

[0084] In one embodiment, after step S5 of controlling the worm to agitate the ice cubes in the ice bin of the ice maker based on the agitation parameter, the following steps are further included:

[0085] S601: Detect the ice bridging ratio of the ice cubes in the ice bin of the ice maker;

[0086] S602: Judge whether the ice bridging ratio is greater than a preset ratio;

[0087] S603: If it is greater than the preset ratio, adjust the constant parameter corresponding to the temperature change rate and the agitation parameter.

[0088] As described in the above steps S601 - S603, the ice - linking ratio of the ice cubes in the ice bin is detected. This ratio is an important indicator for measuring the adhesion situation between ice cubes, and the key lies in reflecting the quality and usability of the ice cubes. The calculation of the ice - linking ratio may include multiple factors, such as the number of ice cubes, whether the ice cubes are in contact with each other, and whether there is a large amount of melted water on the surface of the ice cubes. When the positions of the ice cubes change, accumulated moisture, temperature fluctuations, etc. may cause the ice cubes to gather together, thus forming the ice - linking phenomenon. In some embodiments, the contact area between the ice cubes can be detected by an infrared sensor, and then the proportion of the adhered ice cubes can be calculated to obtain the ice - linking ratio. In a more specific embodiment, since here it is to determine whether to change the parameters, rather than detecting the ice - linking ratio every time, that is, if the user finds that the ice - linking phenomenon is relatively serious during use, the detection of the ice - linking ratio can be triggered. Therefore, here the ice in the ice bin can be directly taken out to determine whether it is ice - linked, so as to achieve the purpose of detecting the ice - linking ratio of the ice cubes in the ice bin. When the ice - linking ratio is greater than the preset ratio, the constant parameter corresponding to the temperature change rate and the stirring parameter is adjusted. Among them, the preset ratio is also a pre - set ratio, formulated based on the device design standard and the actual operating conditions, and can be adjusted according to different occasions and requirements. If the detected ice - linking ratio is greater than this preset value, it indicates that the adhesion situation between the ice cubes is serious, affecting the use and performance of the ice cubes. Calculate the changes in the current environment and the ice cube state, and reset the relevant constants of the stirring parameter according to the new temperature change rate. This dynamic adjustment strategy ensures that the ice maker can flexibly respond under different operating conditions and ice cube states, minimizing the ice - linking risk. By increasing the sensitivity of the temperature change rate or increasing the stirring intensity of the worm, the dispersion of the ice cubes can be effectively promoted, preventing the deterioration of the adhesion phenomenon.
