Description

Technical Field

[0001] This invention relates to the field of ice maker technology, and more specifically, to a quantitative ice-making control method, device, and ice maker. Background Technology

[0002] During actual use of ice makers, the amount of ice produced per batch can fluctuate greatly due to differences in ambient temperature and inlet water temperature, which will affect the actual quality of ice produced per batch.

[0003] Currently, ice makers have a quantitative ice-making function. After entering the quantitative ice-making mode, the unit operates according to logic. The number of times the unit makes ice is controlled by the quantitative relationship between the single ice-making amount under standard working conditions (i.e., the single-time quota ice-making amount) and the target ice-making amount. That is, the number of ice-making times = target ice-making amount / single-time quota ice-making amount, thereby realizing the quantitative ice-making function.

[0004] However, the ice maker's ice-making capacity per batch can be affected by variations in ambient temperature and inlet water temperature. This can lead to problems such as the machine stopping due to excessive ice or insufficient ice production, failing to meet the user's desired ice production volume. In other words, there will be a discrepancy between the actual ice production volume and the target ice production volume, and this discrepancy will become more pronounced as the ambient temperature and inlet water temperature increase or decrease.

[0005] For users, once the unit enters the quantitative ice-making mode, it is impossible to intuitively predict the unit's downtime, which inevitably has an impact on actual use. Furthermore, the actual ice-making time will also fluctuate with the ambient temperature and the inlet water temperature.

[0006] There is currently no effective solution to the problem that existing technologies cannot accurately measure ice quantity. Summary of the Invention

[0007] This invention provides a quantitative ice-making control method, apparatus, and ice maker to at least solve the problem of inaccurate quantitative ice-making in the prior art.

[0008] To address the aforementioned technical problems, embodiments of the present invention provide a quantitative ice-making control method, comprising:

[0009] In quantitative ice-making mode, obtain the current target ice-making amount;

[0010] The actual ice production capacity per batch is determined based on the ambient temperature of the ice maker and the inlet water temperature of the ice maker.

[0011] Based on the target ice production volume and the actual ice production volume in a single batch, determine the required ice production time and output the ice production time;

[0012] The opening degree of the throttling element located between the condenser and evaporator in the ice maker is controlled according to the ice-making time.

[0013] Optionally, the actual ice production capacity per batch is determined based on the ambient temperature of the ice maker and the inlet water temperature of the ice maker, including:

[0014] Determine whether the ambient temperature is within a preset temperature range and whether the inlet water temperature is within a preset water temperature range;

[0015] If the ambient temperature is within a preset temperature range and the inlet water temperature is within a preset water temperature range, then the actual ice production capacity in a single operation is determined to be equal to the rated ice production capacity under standard operating conditions.

[0016] If the ambient temperature is not within the preset temperature range or the inlet water temperature is not within the preset water temperature range, the actual ice production volume for a single batch is determined based on the single-batch ice production volume, the ambient temperature, and the inlet water temperature.

[0020] The sum of the single-time ice production quota, the first correction value, and the second correction value is calculated to obtain the single-time actual ice production volume.

[0021] Optionally, the actual ice production volume per batch can be calculated using the following formula:

[0022] K 单次实际 =K 单次额定 +A×(T 环境额定 -T 环境实际 )+B×(T 进水额定 -T 进水实际 ),

[0023] Among them, K 单次实际 K represents the actual ice production volume in a single batch. 单次额定 T represents the single-use customized ice volume under standard operating conditions. 环境额定 T represents the ambient temperature specified under standard operating conditions. 环境实际 T represents the current actual ambient temperature. 进水额定 T represents the inlet water temperature specified under standard operating conditions. 进水实际 This represents the current actual inlet water temperature. A represents the ambient temperature deviation correction factor, and B represents the inlet water temperature deviation correction factor.

[0024] Optionally, the required ice-making time is determined based on the target ice-making volume and the actual ice-making volume in a single batch, including:

[0025] Calculate the ratio of the target ice production volume to the actual ice production volume in a single batch to obtain the required number of ice production cycles;

[0026] Obtain the single ice-making time corresponding to the actual ice-making volume in a single batch based on the pre-stored information;

[0027] The ice-making time is obtained by multiplying the number of ice-making cycles by the single ice-making time.

[0028] Optionally, controlling the opening degree of the throttling element located between the condenser and evaporator in the ice maker according to the ice-making time includes:

[0029] Compare the ice-making time with the standard time, where the standard time is the time required to produce the target amount of ice under standard operating conditions;

[0030] If the ice-making time is longer than the standard time, the minimum valve opening of the throttling element is adjusted to the first opening, wherein the first opening is greater than the rated opening under standard operating conditions.

[0031] If the ice-making time is less than the standard time, the maximum valve opening of the throttling element is adjusted to a second opening, wherein the second opening is less than the rated opening under standard operating conditions.

[0032] If the ice-making time is equal to the standard time, then the maximum and minimum valve opening of the throttling element remain unchanged.

[0033] This invention also provides a quantitative ice-making control device, comprising:

[0034] The acquisition module is used to acquire the current target ice production amount in quantitative ice-making mode;

[0035] The determining module is used to determine the actual ice production volume per batch based on the ambient temperature of the ice maker and the inlet water temperature of the ice maker.

[0036] The output module is used to determine the required ice-making time based on the target ice-making amount and the actual ice-making amount in a single batch, and to output the ice-making time.

[0037] The control module is used to control the opening degree of the throttling element located between the condenser and the evaporator in the ice maker according to the ice-making time.

[0038] This invention also provides an ice maker, including: the quantitative ice-making control device described in this invention.

[0039] This invention also provides a computer device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the method described in this invention.

[0040] This invention also provides a non-volatile computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the steps of the method described in this invention.

[0041] By applying the technical solution of this invention, in the quantitative ice-making mode, the influence of ambient temperature and inlet water temperature is considered to determine the actual ice-making amount per cycle. The required ice-making time is determined and output based on the actual ice-making amount per cycle. Thus, under any operating condition with different ambient and inlet water temperatures, the actual ice-making amount can be guaranteed to match the user's total target ice-making amount. Moreover, the user can intuitively know the actual ice-making time and understand the ice-making progress, improving the user's ice-making experience. Furthermore, by controlling the opening of the throttling element located between the condenser and evaporator in the ice maker according to the ice-making time, the cooling capacity demand of the unit under variable load conditions can be met, making the quantitative ice-making control more precise and solving the problem of inaccurate quantitative ice-making in the prior art.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them.

[0052] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0053] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0054] The optional embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0055] An ice maker consists of a refrigeration system and a water system. The ice-making process is achieved through the coordinated operation of the refrigeration system and the water system.

[0056] Figure 1 This is a schematic diagram of the refrigeration system of the ice maker provided in an embodiment of the present invention, as shown below. Figure 1As shown, the refrigeration system includes: compressor 21, condenser 22, throttling element 23 (which may be an electronic expansion valve), evaporator 24, dryer filter 25, and ice-collecting solenoid valve 26. Compressor 21 is a fixed-frequency compressor.

[0057] The compressor 21 discharges high-temperature, high-pressure gaseous refrigerant into the condenser 22, where it condenses into a liquid state. After being throttled by the throttling element 23, the liquid enters the evaporator 24, absorbs heat, and vaporizes. It then returns to the compressor 21, completing one refrigeration cycle. If the ice-recovery solenoid valve 26 is opened, the high-temperature exhaust gas from the compressor 21 is directly directed to the evaporator 24, thereby enabling ice removal and ice recovery.

[0058] exist Figure 1 In the diagram, T1 is the exhaust temperature sensor, T2 is the condensation temperature sensor, T3 is the ambient temperature sensor, T4 is the evaporator inlet temperature sensor, and T5 is the evaporator outlet temperature sensor.

[0059] Figure 2 This is a schematic diagram of the water system of the ice maker provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the water system includes: inlet 1, inlet solenoid valve 2, water receiving tray 3, liquid level sensor 4, circulating water pump 5, inlet temperature sensor 6, evaporation ice tray 7, ice thickness sensor 8, water distribution mechanism 9, drain solenoid valve 10, and drain outlet 11.

[0060] The circulating water pump 5 draws water from the water receiving pan 3 to the water distribution mechanism 9, which distributes the water evenly so that it flows down along the evaporating ice plate 7 and freezes on it. The evaporating ice plate 7 in the water system is the evaporator 24 in the refrigeration system. To ensure clean ice making each time, the remaining water in the water receiving pan 3 can be drained through the drain solenoid valve 10 and the drain outlet 11 after ice making is completed.

[0061] This embodiment provides a quantitative ice-making control method that can be applied to ice makers.

[0062] Figure 3 This is a flowchart of the quantitative ice-making control method provided in the embodiments of the present invention, such as... Figure 3 As shown, the method includes the following steps:

[0063] S301, in quantitative ice-making mode, obtains the current target ice-making amount.

[0064] S302 determines the actual ice production volume per cycle based on the ambient temperature of the ice maker and the inlet water temperature of the ice maker.

[0065] S303 determines the required ice-making time based on the target ice-making volume and the actual ice-making volume per batch, and outputs the ice-making time.

[0066] S304 controls the opening degree of the throttling element located between the condenser and evaporator in the ice maker according to the ice-making time.

[0067] To use the quantitative ice-making function, users first need to set the desired total target ice quantity. During the quantitative ice-making process, as the amount of ice already made increases, the remaining target ice quantity gradually decreases. The required ice-making time is determined and updated in real time based on the current remaining target ice quantity, and the ice-making time is output in real time, allowing users to intuitively know the ice-making time and understand the ice-making progress. In other words, at the beginning of quantitative ice-making, the "current target ice quantity" in step S301 is the total target ice quantity set by the user; subsequently, as ice-making progresses, the "current target ice quantity" is the current remaining target ice quantity.

[0068] Ice production capacity per cycle refers to the amount of ice produced during one complete ice production cycle, from ice production to ice collection. Ambient temperature can be obtained using the aforementioned ambient temperature sensor T3, and inlet water temperature can be obtained using the aforementioned inlet water temperature sensor 6.

[0069] In this embodiment, under the quantitative ice-making mode, the influence of ambient temperature and inlet water temperature is considered to determine the actual ice-making amount per cycle. The required ice-making time is determined and output based on the actual ice-making amount per cycle. Thus, under any operating conditions with different ambient and inlet water temperatures, the actual ice-making amount can be guaranteed to match the user's total target ice-making amount. The user can intuitively know the actual ice-making time and understand the ice-making progress, improving the user's ice-making experience. Furthermore, by controlling the opening of the throttling element located between the condenser and evaporator in the ice maker according to the ice-making time, the cooling capacity demand of the unit under variable load conditions can be met, making the quantitative ice-making control more precise and solving the problem of inaccurate quantitative ice-making in the prior art.

[0070] In one embodiment, determining the actual ice production capacity per batch based on the ambient temperature of the ice maker and the inlet water temperature of the ice maker includes: determining whether the ambient temperature is within a preset temperature range and whether the inlet water temperature is within a preset water temperature range; if the ambient temperature is within the preset temperature range and the inlet water temperature is within the preset water temperature range, it indicates that the current operating condition is standard, and the actual ice production capacity per batch is determined to be equal to the rated ice production capacity under standard operating conditions; if the ambient temperature is not within the preset temperature range or the inlet water temperature is not within the preset water temperature range, the actual ice production capacity per batch is determined based on the rated ice production capacity per batch, the ambient temperature, and the inlet water temperature.

[0071] The preset temperature range and preset water temperature range are the temperature intervals corresponding to the standard operating conditions. The preset temperature range can be determined based on the ambient temperature specified in the standard operating conditions. For example, it can be obtained by adjusting the ambient temperature specified in the standard operating conditions by a certain amount above or below. Similarly, the preset water temperature range can also be determined based on the inlet water temperature specified in the standard operating conditions.

[0072] This implementation method can adjust the amount of ice made per batch according to the actual environmental conditions, thereby ensuring that the final amount of ice made meets the user's needs, neither too much nor too little, and can provide the user with an accurate ice-making time based on the actual amount of ice made per batch.

[0073] As the ambient temperature or inlet water temperature increases, the actual amount of ice produced per batch will decrease, and consequently, the required ice-making time will also change.

[0074] Specifically, the actual ice production volume for a single batch is determined based on the customized ice production volume, ambient temperature, and inlet water temperature. This includes: determining the correction value for the ice production volume for a single batch corresponding to the ambient temperature, denoted as the first correction value; determining the correction value for the ice production volume for a single batch corresponding to the inlet water temperature, denoted as the second correction value; and calculating the sum of the customized ice production volume for a single batch with the first correction value and the second correction value to obtain the actual ice production volume for a single batch.

[0075] This implementation method considers the impact of ambient temperature changes and inlet water temperature changes on the single ice production capacity, and combines them with the rated ice production capacity to determine the actual ice production capacity per batch, ensuring that a relatively accurate actual ice production capacity per batch can be obtained under different environmental conditions.

[0076] Preferably, the actual ice production volume per batch can be calculated using the following formula:

[0077] K 单次实际 =K 单次额定 +A×(T 环境额定 -T 环境实际 )+B×(T 进水额定 -T 进水实际 ),

[0078] Among them, K 单次实际 This represents the actual ice production capacity per cycle under the current ambient temperature and current influent water temperature, expressed in K. 单次额定 T represents the amount of custom ice produced in a single test under standard operating conditions. 环境额定 T represents the ambient temperature specified under standard operating conditions. 环境实际 T represents the current actual ambient temperature. 进水额定 T represents the inlet water temperature specified under standard operating conditions. 进水实际 This represents the current actual inlet water temperature. A represents the ambient temperature deviation correction factor, and B represents the inlet water temperature deviation correction factor. The default values ​​for A and B can be 1.

[0079] This embodiment introduces an ambient temperature deviation correction coefficient A to correct for the change in the target ice production capacity caused by changes in ambient temperature, and introduces an inlet water temperature deviation correction coefficient B to correct for the change in the target ice production capacity caused by changes in inlet water temperature, thereby accurately determining the actual ice production capacity per batch.

[0080] In one implementation, determining the required ice-making time based on the target ice-making amount and the actual ice-making amount in a single batch includes: calculating the ratio of the target ice-making amount to the actual ice-making amount in a single batch to obtain the required number of ice-making cycles; obtaining the single ice-making time corresponding to the actual ice-making amount in a single batch based on pre-stored information; and calculating the product of the number of ice-making cycles and the single ice-making time to obtain the ice-making time.

[0081] The pre-stored information refers to the correspondence between the actual amount of ice made in a single operation and the ice-making time in a single operation, which can be obtained through experimental testing.

[0082] This implementation method can determine the accurate ice-making time based on the actual ice-making volume in a single batch, allowing users to view the ice-making progress and improving the user experience.

[0083] In one embodiment, controlling the opening of a throttling element located between the condenser and evaporator in an ice maker based on the ice-making time includes: comparing the ice-making time with a standard time, wherein the standard time is the time required to produce the target amount of ice under standard operating conditions; if the ice-making time is greater than the standard time, adjusting the minimum valve opening of the throttling element to a first opening, wherein the first opening is greater than the rated opening under standard operating conditions; if the ice-making time is less than the standard time, adjusting the maximum valve opening of the throttling element to a second opening, wherein the second opening is less than the rated opening under standard operating conditions; if the ice-making time is equal to the standard time, both the maximum and minimum valve openings of the throttling element remain unchanged.

[0084] The throttling element is set with a corresponding operating range [minimum valve opening, maximum valve opening]. During the operation of the ice maker, the opening of the throttling element must not exceed this operating range. Under standard operating conditions, the rated opening Q of the throttling element under standard operating conditions can be preset. 额定 .

[0085] If the ice-making time exceeds the standard time, it indicates that the unit's current actual load is higher than the standard operating load. In this case, the minimum valve opening of the throttling element can be adjusted to a level greater than the rated opening under standard operating conditions. For example, if the rated opening under standard operating conditions is 75 steps, the adjusted minimum valve opening would be 200 steps. Therefore, even with the throttling element adjusted to its minimum valve opening, the cooling capacity provided by the refrigeration system is still greater than under standard operating conditions. In other words, by increasing the refrigerant flow rate within the refrigeration system, the system's cooling capacity is increased, thereby reducing the ice-making time and achieving control that matches the load.

[0086] If the ice-making time is less than the standard time, it indicates that the unit's current actual load is lower than the standard operating load. In this case, the maximum valve opening of the throttling element can be adjusted to a second degree lower than the rated opening under standard operating conditions. For example, if the rated opening under standard operating conditions is 75 steps, the adjusted maximum valve opening is 50 steps. Therefore, even if the throttling element is adjusted to the maximum valve opening, the cooling capacity provided by the refrigeration system will be less than the cooling capacity under standard operating conditions. This allows for a reduction in system cooling capacity by decreasing the refrigerant flow rate within the refrigeration system, achieving control that matches the load.

[0087] This implementation method, based on the current ice-making time and the standard time, can determine whether the current load of the unit is higher or lower than the standard operating load, and then adjust the operating range of the throttling element accordingly to meet the cooling capacity requirements of the unit under variable load conditions. This results in more precise control and avoids the throttling element from losing synchronization due to an excessively large operating range.

[0088] The following is combined Figure 4 The specific embodiments shown illustrate the above-described quantitative ice-making control method. However, it is worth noting that these specific embodiments are only for better illustrating this application and do not constitute an undue limitation of this application. The same or corresponding terminology as in the above embodiments will not be repeated in this embodiment.

[0089] like Figure 4 The diagram shown is a flow chart for quantitative ice making control, including the following steps:

[0090] S401, the user uses the quantitative ice-making function to set the desired total target ice quantity. During the quantitative ice-making process, the current target ice quantity K is obtained. 目标 (That is, the remaining target amount of ice to be made as ice making progresses), and obtain the ice making time, which is then displayed to the user.

[0091] S402, obtain the ambient temperature T through the unit's ambient temperature sensor T3. 环境实际 The inlet water temperature T is obtained through the inlet water temperature sensing element 6 of the unit. 进水实际 .

[0092] S403, determine whether T is satisfied. 环境额定 -T1≤T 环境实际 ≤T 环境额定 +T1 and T 进水额定 -T2≤T 进水实际 ≤T 进水额定 +T2, if yes, indicates that the current operating condition is standard, and the actual ice production capacity per cycle is the same as the rated ice production capacity per cycle, proceed to S404; otherwise, proceed to S407. T1 is the ambient temperature limit threshold, and T2 is the inlet water temperature limit threshold. T1 and T2 can be used to determine the preset temperature range and the preset water temperature range.

[0093] S404, Calculation and preparation of K目标 Number of ice-making cycles required: K 目标 / K 单次额定 Obtain K based on pre-stored information 单次额定 The corresponding single ice-making time is used to calculate the product of the number of ice-making cycles and the single ice-making time, thus obtaining the ice-making rate K. 目标 The required ice-making time t1 is calculated and output to inform the user.

[0094] S405, the unit's electronic expansion valve (i.e., the aforementioned throttling element 23) is adjusted according to logic; specifically, Q... 额定 As the minimum valve opening.

[0095] S406, run according to the initial logic settings, perform quantitative ice making, and return to S401 to update the ice making time in real time.

[0096] S407, Calculate the current actual ice production volume per cycle: K 单次实际 =K 单次额定 +A×(T 环境额定 -T 环境实际 )+B×(T 进水额定 -T 进水实际 ).

[0097] S408, Calculate the production of K affected by ambient temperature and water temperature fluctuations. 目标 Number of ice-making cycles required: K 目标 / K 单次实际 Obtain K based on pre-stored information 单次实际 The corresponding single ice-making time is used to calculate the product of the number of ice-making cycles and the single ice-making time, thus obtaining the ice-making rate K. 目标 The required ice-making time t2 is calculated and output to inform the user.

[0098] S409, determine whether t1≥t2 is satisfied. If yes, proceed to S410; otherwise, proceed to S411.

[0099] S410, with reduced overall load, the maximum valve opening of the electronic expansion valve is adjusted to Qmin, where Qmin < Q 额定 This reduces the overall refrigerant flow rate during unit operation.

[0100] S411, Due to increased overall load, the minimum valve opening of the electronic expansion valve is adjusted to Qmax, where Qmax > Q. 额定 This increases the refrigerant flow rate during the overall operation of the unit.

[0101] S412, perform quantitative ice making, return to S401 to update the ice making time in real time.

[0102] This embodiment is applicable to quantitative ice making under various environmental conditions. Considering the influence of ambient temperature and inlet water temperature, it uses standard operating condition test data as a scalar and performs quantitative ice making control based on the actual ice making volume in a single operation. This ensures that the actual ice making volume matches the user's target ice making volume and outputs the actual end time of this ice making operation, allowing users to understand the ice making progress and improving the user experience. Furthermore, based on the ice making time, it synchronously judges the changes in the overall unit load and adjusts the operating range of the electronic expansion valve to meet the unit's cooling capacity requirements under variable load conditions, achieving more precise quantitative ice making control.

[0103] Based on the same inventive concept, embodiments of the present invention also provide a quantitative ice-making control device, which can be used to implement the quantitative ice-making control method described in the above embodiments. This quantitative ice-making control device can be implemented through software and / or hardware, and is generally integrated into an ice maker.
