Description

Technical Field

[0001] The present invention relates to the technical field of drinking water equipment, and in particular to a water replenishment control method, device, equipment and storage medium for ice-making and drinking water equipment. Background Art

[0002] The ice-making process of drinking water equipment with ice-making function on the market is that room temperature water is refrigerated by a compressor or ice tank to produce cold water of 0-10℃. The cold water in the cold water tank is then lifted to the ice-making unit through a circulation pump. The cold water sprays downward and evenly covers the surface of the low-temperature evaporator (ice tray) to form ice, realizing live water circulation ice making.

[0003] However, in actual use, it was found that if the user used cold water during the ice-making process, the time to complete the ice-making would be longer, which extended the user's waiting time, and the shape of the ice cubes produced would be irregular, resulting in poor ice-making effect. Summary of the Invention

[0004] In view of this, the present invention provides a water replenishment control method, device, equipment and storage medium for ice-making and drinking water equipment to solve the problem that if the user takes cold water during the ice-making process, the time to complete ice-making will be longer, which will extend the user's waiting time, and the shape of the ice cubes produced will be irregular, resulting in poor ice-making effect.

[0005] In a first aspect, the present invention provides a water replenishment control method for an ice-making and drinking water device, comprising:

[0006] Get the liquid level of the cold water tank;

[0007] When the liquid level of the cold water tank is greater than or equal to the first threshold, water is added after a preset amount of ice is produced.

[0008] Beneficial effect: The first threshold value is the liquid level value corresponding to the amount of water required to make one plate of ice. When the liquid level in the cold water tank is greater than or equal to the first threshold value, it indicates that at least one plate of ice can be made (when equal to the first threshold value), or even a box of ice can be made (when greater than the first threshold value). The preset amount of ice includes the amount of one plate of ice and the amount of one box of ice. After the preset amount of ice is made, water is added to ensure that no water is added during the ice-making process. The water temperature in the cold water tank does not rise during the ice-making process, which will not extend the ice-making time and the user's waiting time, and can also ensure the ice-making effect.

[0009] In an optional embodiment, the water replenishment control method further includes:

[0010] When the liquid level of the cold water tank is greater than or equal to a second threshold, water is added after making a box of ice; the second threshold is greater than the first threshold.

[0011] Beneficial effect: The second threshold is the liquid level value corresponding to the amount of water required to make a box of ice. When the liquid level in the cold water tank is greater than or equal to the second threshold, it indicates that at least one box of ice can be made. In this case, water is added after one box of ice is made. During the ice-making process, no room temperature water is added to the cold water tank, the water temperature will not rise, the ice-making time will not be extended, and the ice-making effect can be ensured.

[0012] In an optional embodiment, the water replenishment control method further includes:

[0013] When the liquid level of the cold water tank is greater than or equal to the first threshold value and less than the second threshold value, water is added after one plate of ice is made and the ice is removed.

[0014] Beneficial effect: The liquid level of the cold water tank is greater than or equal to the first threshold value and less than the second threshold value, indicating that the water amount in the cold water tank is greater than or equal to the cold water amount required to make one plate of ice, and less than the cold water amount required to make one box of ice. The water in the cold water tank is at least enough to make one plate of ice but not enough to make a box of ice. At this time, after making one plate of ice and in the defrosting state, water is added, which effectively utilizes the defrosting time and can minimize the ice making time.

[0015] In an optional embodiment, the water replenishment control method further includes:

[0016] When it is detected that a user takes cold water, and the amount of water taken is less than or equal to the difference between the total capacity of the cold water tank and the amount of cold water required to make a box of ice, water will be added after making a box of ice.

[0017] Beneficial Effect: By determining whether a user has drawn water, the remaining water level in the cold water tank is indirectly reflected. This eliminates the need for a liquid level sensor. Instead, the remaining water level in the cold water tank can be calculated directly by determining the user's water withdrawal action and the amount of water withdrawn. This reduces the cost of adding a water level sensor to the cold water tank. If the amount of water withdrawn is less than or equal to the difference between the total cold water tank capacity and the amount of cold water required to make one box of ice, the remaining water level is sufficient to make one box of ice. In this case, water can be added after making one box of ice, meaning no water is added during the ice-making process. This prevents extended ice-making time and ensures optimal ice-making results.

[0018] In an optional embodiment, the water replenishment control method further includes:

[0019] When it is detected that a user takes cold water, and the amount of water taken is greater than the difference between the total capacity of the cold water tank and the amount of cold water required to make a box of ice, water will be added after one plate of ice is made and the ice is defrosted.

[0020] Beneficial effect: When the amount of water taken is greater than the difference between the total capacity of the cold water tank and the amount of cold water required to make a box of ice, it indicates that the remaining water is insufficient to make a box of ice. At this time, water is added during the defrosting state after each sheet of ice is made, effectively utilizing the defrosting time to add water without affecting the ice making process.

[0021] In an optional embodiment, the water replenishment control method further includes:

[0022] Get the water temperature of the mixed water in the cold water tank;

[0023] When the temperature of the mixed water in the cold water tank is less than or equal to the preset water temperature, the single water replenishment amount is controlled to be twice the amount of cold water required to make one plate of ice.

[0024] Beneficial effect: If the temperature of the mixed water is low, the amount of room temperature water added should be less. However, at this time, it is also necessary to consider the situation where the water level in the cold water tank is low and the water volume needs to be increased quickly. Therefore, through comprehensive calculation, twice the amount of cold water required to make one plate of ice is added here. This can not only meet the need to quickly increase the water level in the cold water tank, but also ensure that the temperature of the mixed water is within a controllable range, further ensuring that the ice making time will not be too long.

[0025] In an optional embodiment, the water replenishment control method further includes:

[0026] When the temperature of the mixed water in the cold water tank is higher than the preset water temperature, the single water replenishment amount is controlled to be 1 / 2 of the cold water amount required to make one plate of ice.

[0027] Beneficial effect: When the temperature of the mixed water in the cold water tank is higher than the preset water temperature, it indicates that the temperature of the mixed water is relatively high. You can add less water. The single water replenishment amount can be set to 1 / 2 of the cold water required to make one plate of ice, so as to avoid the high mixed water temperature from increasing too quickly and ensure the ice-making effect.

[0028] In an optional embodiment, the water replenishment control method further includes:

[0029] When the liquid level of the cold water tank is lower than the first threshold, the user is restricted from taking cold water and is required to replenish water.

[0030] Beneficial effect: When the liquid level in the cold water tank is lower than the first threshold, it indicates that the water in the cold water tank is insufficient to make one plate of ice. To ensure ice making, it is necessary to restrict users from taking cold water and replenish water to avoid the situation where ice cannot be made due to lack of water.

[0031] In an optional embodiment, the water replenishment control method further includes:

[0032] When the liquid level of the cold water tank is lower than the first threshold, the water replenishment speed is increased until the liquid level is greater than or equal to the first threshold.

[0033] Beneficial effect: When the liquid level in the cold water tank is lower than the first threshold, it indicates that the water in the cold water tank is insufficient to produce one plate of ice. In this case, emergency water replenishment is required until the water level is sufficient to produce one plate of ice and then the replenishment is stopped. This avoids the situation where ice cannot be made due to lack of water, and only the amount of water required to produce one plate of ice is replenished, thereby minimizing the energy consumption caused by the replenishment of room temperature water.

[0034] In an optional embodiment, increasing the water replenishment speed includes:

[0035] Control and increase the motor speed of the water supply pump so that the water supply flow rate is greater than the cold water supply flow rate.

[0036] Beneficial effect: By increasing the motor speed of the water supply pump to increase the water supply flow, it is easy to control and adjust, so that the water supply flow is greater than the flow of cold water, completing emergency accelerated water supply and ensuring that there is always cold water for ice making.

[0037] In an optional embodiment, the water replenishment control method further includes:

[0038] Get the liquid level of the cold water tank after starting the machine;

[0039] When the liquid level in the cold water tank is lower than the third threshold, water replenishment is started until the liquid level in the cold water tank is equal to the third threshold.

[0040] Beneficial effect: The third threshold is the liquid level value corresponding to the full liquid in the cold water tank (maximum liquid level). When refrigeration or ice making is not turned on after the machine is turned on, water replenishment will not affect ice making. Therefore, water replenishment can be directly controlled until the cold water tank is full, reducing the impact of water replenishment on ice making after starting refrigeration or ice making.

[0041] In an optional embodiment, the water replenishment control method further includes:

[0042] When the liquid level in the cold water tank is equal to the third threshold, the current working state is maintained or water replenishment is stopped.

[0043] Beneficial effect: When the machine is in a full liquid state at startup, the current working state is maintained, and when the water replenishment reaches the full liquid state, the water replenishment is stopped, ensuring sufficient water volume while avoiding overflow.

[0044] In an optional embodiment, the water replenishment control method further includes:

[0045] After turning on refrigeration or ice making, when it is detected that no user takes cold water and the ice box is full, when the cold water tank level is less than the third threshold, water is continuously replenished until the cold water tank level is equal to the third threshold.

[0046] Beneficial effect: If no user takes cold water, the only cold water consumption is for ice making. At this time, it is determined whether the ice box is full. If the ice box is full, it indicates that ice making is not currently needed and water replenishment will not affect ice making. Water can be replenished as needed. When the cold water tank is not full, the water replenishment pump is directly controlled to continuously replenish water until the cold water tank is full.

[0047] In an optional embodiment, the water replenishment control method further includes:

[0048] When it is detected that no user is taking cold water and the ice box is not full, the current working state is maintained.

[0049] Beneficial effect: When no user takes cold water, only ice making consumes cold water. Since the amount of cold water consumed by ice making is small and the amount of cold water in the cold water tank is still sufficient, when the ice box is not full, full ice making is performed without water replenishment, so as to avoid the influence of water temperature increase on ice making.

[0050] In a second aspect, the present invention further provides a water replenishment control device for an ice-making and drinking water device, comprising:

[0051] An acquisition module is used to obtain the liquid level of the cold water tank;

[0052] The control module is used for producing a preset amount of ice and then replenishing water when the liquid level of the cold water tank is greater than or equal to a first threshold.

[0053] Beneficial effects: The liquid level of the cold water tank is obtained through the acquisition module, and the control module is used to make a preset amount of ice and then add water when the liquid level of the cold water tank is greater than or equal to the first threshold, ensuring that no water is added during the ice-making process, the water temperature in the cold water tank does not rise during the ice-making process, and the ice-making time and user waiting time will not be extended, and the ice-making effect can also be ensured.

[0054] In a third aspect, the present invention further provides a computer device, comprising:

[0055] A memory and a processor, wherein the memory and the processor are communicatively connected to each other, the memory stores computer instructions, and the processor executes the water replenishment control method of the ice making and drinking water equipment described in any one of the above items by executing the computer instructions.

[0056] Beneficial effect: The processor executes the water replenishment control method of the ice-making and drinking water equipment of the present invention by executing the computer instructions stored in the memory. When the liquid level of the cold water tank is greater than or equal to the first threshold, water is replenished after a preset amount of ice is made, ensuring that water is not replenished during the ice-making process, the water temperature in the cold water tank does not rise during the ice-making process, the ice-making time and the user's waiting time will not be extended, and the ice-making effect can also be ensured.

[0057] In a fourth aspect, the present invention further provides a computer-readable storage medium having computer instructions stored thereon, wherein the computer instructions are used to enable a computer to execute any of the above-mentioned water replenishment control methods for ice-making and drinking water equipment.

[0058] Beneficial effect: By executing computer instructions stored on a computer-readable storage medium, the computer executes the water replenishment control method for the ice-making and drinking water equipment of the present invention. When the liquid level in the cold water tank is greater than or equal to the first threshold, water is replenished after a preset amount of ice is made, ensuring that water is not replenished during the ice-making process, the water temperature in the cold water tank does not rise during the ice-making process, the ice-making time and the user's waiting time will not be extended, and the ice-making effect can also be ensured.

[0075] The following combination Figures 1 to 12 , describing embodiments of the present invention.

[0076] According to an embodiment of the present invention, on the one hand, Figure 1As shown, a water replenishment control method for an ice-making and drinking water device is provided, comprising:

[0077] Get the liquid level of the cold water tank;

[0078] When the liquid level of the cold water tank is greater than or equal to the first threshold, water is added after a preset amount of ice is produced.

[0079] The first threshold is the liquid level value corresponding to the amount of water required to make one plate of ice. When the liquid level in the cold water tank is greater than or equal to the first threshold, it indicates that at least one plate of ice can be made (when equal to the first threshold), or even a box of ice can be made (when greater than the first threshold). The preset amount of ice includes the amount of one plate of ice and one box of ice. After the preset amount of ice is made, water is added to ensure that no water is added during the ice-making process. The water temperature in the cold water tank does not rise during the ice-making process, which will not extend the ice-making time and the user's waiting time, and can also ensure the ice-making effect.

[0080] In some embodiments, as Figure 2 As shown, the water replenishment control method further includes:

[0081] When the liquid level of the cold water tank is greater than or equal to a second threshold, water is added after making a box of ice; the second threshold is greater than the first threshold.

[0082] The second threshold is the liquid level value corresponding to the amount of water required to make a box of ice. When the liquid level in the cold water tank is greater than or equal to the second threshold, it indicates that at least one box of ice can be made. In this case, water is added after one box of ice is made. During the ice-making process, no room temperature water is added to the cold water tank, the water temperature does not rise, the ice-making time will not be extended, and the ice-making effect can be ensured.

[0083] In some embodiments, as Figure 3 As shown, the water replenishment control method further includes:

[0084] When the liquid level of the cold water tank is greater than or equal to the first threshold value and less than the second threshold value, water is added after one plate of ice is made and the ice is removed.

[0085] The liquid level in the cold water tank is greater than or equal to the first threshold and less than the second threshold, indicating that the water volume in the cold water tank is greater than or equal to the cold water volume required to make one plate of ice and less than the cold water volume required to make one box of ice. The water in the cold water tank is at least enough to make one plate of ice but not enough to make a box of ice. In this case, water is added after making one plate of ice and in the defrosting state, effectively utilizing the defrosting time and thus shortening the ice-making time to the maximum extent.

[0086] In some embodiments, as Figure 4 As shown, the water replenishment control method further includes:

[0087] When it is detected that a user takes cold water, and the amount of water taken is less than or equal to the difference between the total capacity of the cold water tank and the amount of cold water required to make a box of ice, water will be added after making a box of ice.

[0088] By determining whether a user has drawn water, the remaining water level in the cold water tank is indirectly reflected. This eliminates the need for a level sensor. By directly determining the user's water withdrawal and the amount of water withdrawn, the remaining water level in the cold water tank can be calculated. This reduces the cost of adding a water level sensor to the cold water tank. If the water withdrawal amount is less than or equal to the difference between the total cold water tank capacity and the amount of cold water required to make one box of ice, the remaining water level is sufficient for making one box of ice. In this case, water can be added after making one box of ice. This eliminates the need for water addition during the ice-making process, preventing extended ice-making time and ensuring optimal ice-making results.

[0089] In some embodiments, as Figure 5 As shown, the water replenishment control method further includes:

[0090] When it is detected that a user takes cold water, and the amount of water taken is greater than the difference between the total capacity of the cold water tank and the amount of cold water required to make a box of ice, water will be added after one plate of ice is made and the ice is defrosted.

[0091] If the amount of water taken is greater than the difference between the total capacity of the cold water tank and the amount of cold water required to make a box of ice, it means that the remaining water is insufficient to make a box of ice. In this case, water is added during the defrosting state after each sheet of ice is made, which effectively utilizes the defrosting time for water addition without affecting the ice making process.

[0092] In some embodiments, as Figure 6 As shown, the water replenishment control method further includes:

[0093] Get the water temperature of the mixed water in the cold water tank;

[0094] When the temperature of the mixed water in the cold water tank is less than or equal to the preset water temperature, the single water replenishment amount is controlled to be twice the amount of cold water required to make one plate of ice.

[0095] If the temperature of the mixed water is low, the amount of room temperature water added should be even less. However, at this time, we also need to consider the situation where the water level in the cold water tank is low and the water volume needs to be increased quickly. Therefore, through comprehensive calculation, twice the amount of cold water required to make one plate of ice is added here. This can not only meet the need to quickly increase the water level in the cold water tank, but also ensure that the temperature of the mixed water is within a controllable range, further ensuring that the ice making time will not be too long.

[0096] In some embodiments, as Figure 6 As shown, the water replenishment control method further includes:

[0097] When the temperature of the mixed water in the cold water tank is higher than the preset water temperature, the single water replenishment amount is controlled to be 1 / 2 of the cold water amount required to make one plate of ice.

[0098] When the temperature of the mixed water in the cold water tank is higher than the preset water temperature, it indicates that the temperature of the mixed water is relatively high. You can add less water. The single water replenishment amount can be set to 1 / 2 of the amount of cold water required to make one plate of ice to avoid the higher mixed water temperature from increasing too quickly and ensure the ice-making effect.

[0099] In some embodiments, as Figure 7 As shown, the water replenishment control method further includes:

[0100] When the liquid level of the cold water tank is lower than the first threshold, the user is restricted from taking cold water and is required to replenish water.

[0101] The liquid level in the cold water tank is lower than the first threshold, indicating that the water in the cold water tank is insufficient to make one sheet of ice. To ensure ice making, it is necessary to restrict users from taking cold water and replenish water to avoid the situation where ice cannot be made due to lack of water.

[0102] In some embodiments, as Figure 8 As shown, the water replenishment control method further includes:

[0103] When the liquid level in the cold water tank is lower than the first threshold, the emergency accelerated water replenishment is started to increase the water replenishment speed until the liquid level is greater than or equal to the first threshold.

[0104] When the liquid level in the cold water tank is lower than the first threshold, it indicates that the water in the cold water tank is insufficient to produce one sheet of ice. In this case, emergency water replenishment is required until the water level is sufficient to produce one sheet of ice. Then, water replenishment is stopped to avoid the situation where ice cannot be produced due to lack of water. In addition, water is only replenished to the amount sufficient to produce one sheet of ice, thereby minimizing the energy consumption caused by replenishing water at room temperature.

[0105] The water replenishment stage of the ice making and drinking water equipment includes:

[0106] The first stage of water replenishment refers to the water replenishment during the load-not-operating stage after the ice-making and drinking water equipment is turned on;

[0107] The second stage of water replenishment refers to the water replenishment when there is no user taking cold water after turning on refrigeration or ice making;

[0108] The third stage of water replenishment refers to the water replenishment after the refrigeration or ice making is turned on, when a user takes cold water and the liquid level in the cold water tank has reached the minimum;

[0109] The fourth stage of water replenishment refers to the water replenishment when a user takes cold water after the refrigeration water or ice making is turned on and the liquid level in the cold water tank has not reached the minimum;

[0110] The water replenishment control method comprises:

[0111] Based on the principle of giving priority to ice making, water replenishment is controlled in a targeted manner according to different water replenishment stages of the ice making and drinking water equipment.

[0112] The water replenishment control method for ice-making and drinking water equipment of the present invention takes ice making as a priority and controls water replenishment in a targeted manner according to different water replenishment stages of the ice-making and drinking water equipment, thereby ensuring that the influence of the water replenishment process on the ice-making time and ice-making effect can be reduced in different water replenishment stages, thereby preventing the ice-making time from being prolonged, shortening the user's waiting time, avoiding a large increase in the cold water temperature, ensuring the ice cube forming effect, and improving the user experience.

[0113] In some embodiments, the water replenishment control method includes:

[0114] After powering on, obtain the liquid level status of the cold water tank and determine whether the liquid level of the cold water tank has reached a third threshold;

[0115] When the liquid level in the cold water tank does not reach the third threshold, the first stage of water replenishment is entered, and the water replenishment pump is controlled to start until the liquid level in the cold water tank reaches the third threshold.

[0116] After powering on the machine, the first step is to check whether the cold water tank level has reached the third threshold. This indicates the tank is full. If it has not, water replenishment is required. Since cooling or ice making has not yet been activated, replenishing water at this time will not affect ice making. Therefore, the replenishment pump can be directly controlled to start replenishing water until the cold water tank is full, minimizing the impact of replenishing water after cooling or ice making has been activated.

[0117] In some embodiments, the water replenishment control method further includes:

[0118] When the liquid level in the cold water tank reaches the third threshold, the water supply pump is not started or is shut down.

[0119] During the startup phase, when the liquid level in the cold water tank reaches the third threshold, the water replenishment pump will not be started. During the startup water replenishment phase, if the water level in the cold water tank is full, the water replenishment pump will be shut down in time.

[0120] In some embodiments, the water replenishment control method includes:

[0121] After turning on refrigeration or ice making, determine whether there is a user taking cold water;

[0122] When no user takes cold water, the second stage of water replenishment is entered to determine whether the ice box is full;

[0123] When the ice box is full, it is determined whether the liquid level in the cold water tank has reached a third threshold;

[0124] When the liquid level in the cold water tank does not reach the third threshold, the water replenishment pump is controlled to continuously replenish water until the liquid level in the cold water tank reaches the third threshold.

[0125] After turning on refrigeration or ice making, if no user takes cold water, the cold water consumption is only for ice making. At this time, it is determined whether the ice box is full. If the ice box is full, it means that ice making is not currently needed and water replenishment will not affect ice making. Water can be replenished as needed. When the cold water tank is not full, the water replenishment pump is directly controlled to continuously replenish water until the cold water tank is full.

[0126] By judging whether there is a user taking cold water and the amount of water taken, the remaining water amount can be indirectly reflected. Compared with directly detecting through the liquid level sensor in the water tank, the remaining water amount in the water tank can be indirectly reflected by judging the user's water taking action and the amount of water taken. This can reduce the cost of adding a water level sensor in the water tank.

[0127] In some embodiments, the water replenishment control method further includes:

[0128] When the ice box is full and the liquid level in the cold water tank has reached the third threshold, water replenishment is stopped.

[0129] If the ice box is full, it means that ice making is not needed at present, and adding water will not affect ice making. If the ice box is full, it means that ice making is not needed either. In this case, you can stop adding water when the cold water tank is full.

[0130] In some embodiments, the water replenishment control method further includes:

[0131] When no user takes cold water and the ice box is not full, water will not be replenished.

[0132] When no user takes cold water, only ice making consumes cold water. Since the amount of cold water consumed by ice making is small and the amount of cold water in the cold water tank is still sufficient, when the ice box is not full, full ice making is performed without water replenishment to avoid the impact of water replenishment on ice making.

[0133] In some embodiments, the water replenishment control method further includes:

[0134] After turning on refrigeration or ice making, when a user takes cold water, the third stage of water replenishment is entered to determine whether the liquid level in the cold water tank drops to the first threshold;

[0135] When the liquid level in the cold water tank has dropped to a first threshold, users are restricted from taking cold water, and the water replenishment pump is controlled to start replenishing water.

[0136] After turning on refrigeration or ice making, when a user draws cold water, the cold water consumption includes the user's water drawing and ice making. At this time, it is determined whether the liquid level in the cold water tank has dropped to the first threshold. Dropping to the first threshold indicates that there is no cold water or the water drawing limit has been reached or it is not enough to make a plate of ice. At this time, it is necessary to restrict users from drawing cold water, shut down the water drawing pump, and start the water replenishment pump to replenish water in time. Quick water replenishment ensures the amount of cold water for ice making.

[0137] In some embodiments, after restricting users from taking cold water and controlling the water replenishment pump to start replenishing water, the method further includes:

[0138] Determining whether the liquid level in the cold water tank reaches a third threshold;

[0139] When the liquid level in the cold water tank has not reached the third threshold, the water replenishment speed is increased to continue replenishing water until the liquid level in the cold water tank reaches the third threshold.

[0140] When the water tank level does not reach the third threshold, in order to ensure that there is no shortage of cold water during ice making, it is necessary to speed up the water replenishment and perform emergency water replenishment until the cold water tank is full.

[0141] In some embodiments, increasing the water replenishment rate includes:

[0142] Control and increase the motor speed of the water supply pump so that the water supply flow rate is greater than the cold water supply flow rate.

[0143] Increase the motor speed of the water supply pump to increase the water supply speed, so that the water supply flow rate is greater than the cold water withdrawal flow rate, thereby replenishing the cold water consumed by the cold water withdrawal while ensuring that the liquid level in the cold water tank can increase rapidly.

[0144] In some embodiments, when the liquid level in the cold water tank reaches a third threshold, water replenishment is stopped.

[0145] Stop adding water in time when the cold water tank is full to save energy.

[0146] In some embodiments, the water replenishment control method further includes:

[0147] After turning on refrigeration or ice making, when a user takes cold water and the liquid level in the cold water tank has not dropped to the first threshold, the fourth stage of water replenishment is entered;

[0148] Obtain the user's cold water consumption and determine whether the cold water consumption is greater than the difference between the total capacity of the cold water tank and the amount of cold water required to make a full box of ice;

[0149] When the amount of cold water taken is greater than the difference between the total capacity of the cold water tank and the amount of cold water required to make a full box of ice;

[0150] When the required water amount is not enough to make a full box of ice, water is added during the de-icing process of each sheet of ice, and water is added multiple times until the required water amount is enough to make a full box of ice.

[0151] When a user draws cold water and the cold water tank level hasn't dropped to the first threshold, indicating there's still some cold water in the tank for ice making, the system determines the user's water withdrawal amount and whether the remaining ice water is sufficient to make a full box of ice. If not, water replenishment is required. To ensure the ice-making process is not affected, water is added during the defrosting process after a sheet of ice is produced (after a sheet of ice is produced, the ice cubes are poured into the ice box; several sheets of ice can fill the ice box). This ensures water replenishment while minimizing ice-making time. Multiple water replenishments ensure that the added room-temperature water mixes thoroughly with the ice water in the cold water tank, ensuring the temperature of the mixed water is sufficiently low, which is beneficial for improving ice-making results.

[0152] In some embodiments, the replenishing of water during the de-icing process of each ice sheet includes determining a single replenishing amount of water, and the determining a single replenishing amount of water includes:

[0153] Get the temperature of the mixed water in the cold water tank and determine whether it is less than or equal to the preset water temperature;

[0154] When the temperature of the mixed water in the cold water tank is less than or equal to the preset water temperature, the single water replenishment amount is twice the amount of cold water required to make one plate of ice.

[0155] The single water replenishment amount is determined based on the water temperature of the mixed water in the cold water tank. When the water temperature of the mixed water in the cold water tank is less than or equal to the preset water temperature, it indicates that the temperature of the mixed water is relatively low and you can add more water. The single water replenishment amount can be set to twice the amount of cold water required to make one plate of ice. This ensures that the water temperature of the mixed water will not increase too quickly while ensuring the water replenishment amount.

[0156] If the temperature of the mixed water is low, the amount of room temperature water added should be even less. However, at this time, we also need to consider the situation where the water level in the cold water tank is low and the water volume needs to be increased quickly. Therefore, through comprehensive calculation, twice the amount of cold water required to make one plate of ice is added here. This can not only meet the need to quickly increase the water level in the cold water tank, but also ensure that the temperature of the mixed water is within a controllable range, further ensuring that the ice making time will not be too long.

[0157] In some embodiments, the water replenishment control method further includes:

[0158] When the temperature of the mixed water in the cold water tank is higher than the preset water temperature, the single water replenishment amount is 1 / 2 of the cold water amount required to make one plate of ice.

[0159] When the temperature of the mixed water in the cold water tank is higher than the preset water temperature, it indicates that the temperature of the mixed water is relatively high. You can add less water. The single water replenishment amount can be set to 1 / 2 of the amount of cold water required to make one plate of ice to avoid the higher mixed water temperature from increasing too quickly and ensure the ice-making effect.

[0160] In some embodiments, the preset water temperature is 10°C.

[0161] Water between 0 and 10°C is considered cold water, so the preset water temperature is set to 10°C. If the temperature is lower than 10°C, it means the water temperature is low, and the mixed water temperature will not drop much after replenishing water. If the temperature is higher than 10°C, it means the mixed water in the cold water tank is no longer the cold water specified in the national standard. At this time, the amount of water replenishment needs to be controlled so that the replenishment process does not cause the mixed water temperature to rise too quickly.

[0162] In some embodiments, the water replenishment control method further includes:

[0163] When the amount of cold water taken is greater than or equal to the difference between the total capacity of the cold water tank and the amount of cold water required to make a full box of ice, and the required amount of water is enough to make a full box of ice, the water replenishment pump is started and the water replenishment is stopped after the liquid level in the cold water tank reaches the maximum level.

[0164] When there is still a certain amount of cold water in the cold water tank that can be used for ice making, and the amount of cold water added after taking water is enough to make a full box of ice, you can stop adding water after the cold water tank is filled to avoid affecting ice making. At the same time, the amount of cold water is also sufficient to make a box of ice.

[0165] In some embodiments, the water replenishment control method further includes:

[0166] When the amount of cold water taken is less than the difference between the total capacity of the cold water tank and the amount of cold water required to make a full box of ice, it is necessary to wait until a box of ice is made before adding water.

[0167] When the amount of cold water taken is less than the remaining cold water in the cold water tank after making a full box of ice, there is no need to replenish water to ensure that ice making is given priority.

[0168] The invention of ice-making drinking water equipment also has the function of cooling water when the ice-making function is turned on, and gives priority to ensuring the realization of ice cubes. The ice-making temperature range of general drinking water equipment is 0-1°C, and the temperature range of cold water is 0-10°C.

[0169] The mixed water in the cold water tank is consumed by users taking out cold water and making ice.

[0170] When the cold water in the cold water tank is consumed, when to replenish water so as not to affect ice making is the focus of the present invention.

[0171] The temperature of the mixed water after the normal temperature water is added and the cold water flowing into the cold water tank after cooling is T 混合 See also Figure 9 The water replenishment stages of the ice-making and drinking water equipment include the first stage water replenishment, the second stage water replenishment, the third stage water replenishment and the fourth stage water replenishment, which are explained below respectively.

[0172] 1) The first stage of water replenishment (also known as power-on water replenishment)

[0173] The system starts replenishing water when the whole machine is powered on to ensure that there is sufficient water for cooling or ice making every time the machine is powered on.

[0174] 2) Second stage hydration (also known as continuous hydration)

[0175] If the user does not take cold water (water in the cold water tank), for the cold water consumed by ice making, when to replenish water needs to consider whether it will affect the ice making time and ice making effect. 混合 It should not affect the ice making effect. If you keep adding room temperature water, it will make T 混合If the temperature is too high, the condensed water will melt, prolonging the ice making process and affecting the ice making effect. Ice cubes can be shaped like square or bullet. When making ice, the ice cubes must be regular in shape, transparent, icy, and free of cracks.

[0176] Therefore, after making a full box of ice, water is added (it is estimated that a full box of ice consumes half the total capacity of the cold water tank). At this point, the ice box is full, and there is no need to worry about the impact of water addition. Although a small amount of cold water is consumed during each plate of ice making, this does not require water addition. In other words, water is added when the ice full sensor is activated until the cold water tank reaches the third threshold. Specifically, the ice fullness is determined by the infrared sensor.

[0177] 3) The third stage of water replenishment (also known as emergency water replenishment)

[0178] If a user is constantly drawing cold water, you need to limit their water draw. That is, when the user reaches the first threshold of the cold water tank, stop drawing cold water and prioritize ice making. This stops the user from drawing cold water by directly shutting down the water pump, with a display and buzzer alerting the user.

[0179] When there is still a small amount of residual cold water in the cold water tank, it can still meet the needs of ice making, but the cold water tank is no longer full of water, so it should be ensured that there is enough water to meet the needs of ice making.

[0180] In order not to prolong the ice making time and affect the ice making effect, the water replenishment at this time should ensure that the flow rate of normal temperature water replenishment must keep up with the water intake flow rate of cold water until the third threshold of the cold water tank is reached.

[0181] 4) The fourth stage of hydration (also known as de-icing and hydration)

[0182] If the remaining water after the user dispenses is insufficient to make a full box of ice, that is, the amount of water dispensed ≥ (total cold water tank capacity - water required to make a full box of ice), then water refilling is required. Assume the total cold water tank capacity is 1000ml and the amount of water required to make a full box of ice is 500ml. If the amount of water dispensed ≥ (1000-500)ml, then water refilling is required.

[0183] At this time, it should be ensured that there is enough water to meet the needs of ice making, and the temperature of the mixed water in the cold water tank should be low enough to avoid increasing the ice making time and ice making effect.

[0184] Therefore, water needs to be added during the ice-making process, that is, after ice-making is complete and during the defrosting process. The total water replenishment is the amount needed to make a full box of ice, and this replenishment is done in multiple steps, with each step equal to the amount consumed during one ice-making cycle. This replenishment is defined as defrosting replenishment. A complete ice-making cycle takes approximately 8 seconds. The purpose of these multiple replenishments is to ensure that the added room-temperature water mixes thoroughly with the cold water in the ice tank, ensuring a sufficiently low temperature for the mixed water.

[0185] It should be noted that making one sheet of ice is estimated to consume 125ml of cold water, and making a full box of ice requires making 4 sheets of ice (also known as making ice 4 times).

[0186] Each time you add water, add water based on the detected mixed water temperature. If the mixed water temperature is detected to be ≤10°C (the cold water cutoff point), add more water, specifically twice the amount of cold water consumed for one ice making cycle. If the mixed water temperature is >10°C, add less water, specifically 1 / 2 the amount of cold water consumed for one ice making cycle.

[0187] If the amount of cold water left after the user takes it out is still enough to make a full box of ice, there is no need to add water. That is, when the amount of cold water taken out is less than 500ml, there is no need to add water.

[0188] After a box of ice is full, water is added, that is, when the ice full sensor is detected, water is added until the third threshold of the cold water tank is reached.

[0189] The present invention focuses on analyzing when and how to replenish water when the mixed water in the cold water tank is consumed so that the temperature of the mixed water in the water tank is sufficiently low, and proposes a water replenishment control method for ice-making and drinking water equipment. The method defines power-on water replenishment, continuous water replenishment, emergency water replenishment and ice-removal water replenishment. Timely, effective and reasonable water replenishment can maintain a good ice-making effect and shorten the ice-making time, thereby improving the user experience.

[0190] In some embodiments, when the water level in the cold water tank is insufficient to produce a plate of ice, emergency accelerated water replenishment is started until the water volume meets the water volume for producing a plate of ice, then the de-icing and water replenishment stage is entered and the single water replenishment volume is adjusted according to the water temperature. Finally, in this stage, the water volume is slowly replenished to the volume that can produce a box of ice. At the same time, the accelerated water replenishment in the emergency water replenishment can also be maintained until the water volume for producing a box of ice is met and the accelerated water replenishment is stopped.
