Description

Technical Field

[0001] The present invention relates to the technical field of ice making machines, and in particular to an ice making machine control method, an ice making machine control device and an ice making machine. Background Art

[0002] An ice maker is a refrigeration mechanical device that generates ice by cooling water through an evaporator with the refrigerant of the refrigeration system. It uses a refrigeration system and a water carrier to make ice by passing through a certain device under power-on state. In the specific ice-making process, water automatically enters a water storage tank through the water inlet valve, and then is sent to the diverter head through a water pump through a flow control valve, where the water is evenly sprayed on the surface of the ice maker and flows through the wall of the ice maker. The water is cooled to the freezing point, and the water that has not been evaporated and frozen will flow into the water storage tank through the porous groove and restart the circulation. When the ice reaches the required thickness, it enters the de-icing state, and the high-pressure hot air discharged from the compressor is diverted to the evaporator through the reversing valve to replace the low-temperature liquid refrigerant. In this way, a layer of water film is formed between the ice and the evaporator. This layer of water film causes the ice to separate from the evaporator, and the ice falls freely into the ice storage tank below by gravity.

[0003] In the prior art, the ice maker detects the height change of the liquid level in the water storage tank through a liquid level sensor and controls the water pump and the water inlet valve. When the liquid level sensor fails, the system will stop immediately, resulting in incomplete ice cubes being made at the moment, and ice cubes still remaining in the ice tray. When making the next plate of ice, the remaining ice cubes need to be processed, which wastes time and reduces ice making efficiency.

[0004] With regard to the problem in the related art that ice making stops when the liquid level sensor of the ice maker fails and the remaining ice cubes affect the next ice making process, no effective solution has been proposed yet. Summary of the invention

[0010] Furthermore, after controlling the ice maker to continue making ice, or controlling the water inlet valve of the ice maker to let water in to complete the current ice making, it also includes: after completing the current ice making, controlling the ice maker to stop, and issuing a failure alarm for the liquid level sensor.

[0011] Furthermore, controlling water intake through the water inlet valve of the ice maker also includes: obtaining the ice-making mode of the current ice-making; determining whether the water demand of the ice-making mode of the current ice-making is the ice-making mode with the smallest water demand; if so, triggering the control of the water inlet valve of the ice maker to intake water; otherwise, determining whether there are other ice-making modes whose current water storage capacity of the water storage tank can meet the ice-making demand, and if so, switching the ice-making mode of the current ice-making to the other ice-making mode, and controlling the ice-making machine to continue making ice according to the other ice-making mode.

[0012] Furthermore, before the liquid level sensor of the ice maker water tank fails, it also includes: acquiring liquid level data detected by the liquid level sensor; determining whether the liquid level data is valid; when the number of invalid times of the liquid level data reaches a preset number, determining that the liquid level sensor has failed, otherwise, determining that the liquid level sensor has not failed.

[0013] According to another aspect of an embodiment of the present invention, an ice maker control device is provided, comprising: an acquisition module, for acquiring the liquid level data detected by the liquid level sensor for the last time when the liquid level sensor of the water tank of the ice maker fails; a judgment module, for judging whether the current water storage capacity of the water tank meets the current ice making demand according to the liquid level data; and a control module, for controlling the ice maker to continue making ice if so, and otherwise controlling the water inlet valve of the ice maker to let water in so as to complete the current ice making.

When the liquid level sensor of the water tank of the ice maker fails, the liquid level data detected by the liquid level sensor for the last time is obtained, and it is judged whether the current water storage capacity of the water tank meets the ice making demand at the time according to the liquid level data. When it meets the demand, the ice maker operates normally to ensure that the ice making process continues.

[0027] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] In a preferred embodiment 1 of the present invention, an ice making machine control method is provided, and the control method can be directly applied to various ice making machines. Specifically, Figure 1 An optional structural schematic diagram of the ice maker is shown, such as Figure 1 As shown, the ice making machine comprises:

[0030] Water pump: responsible for pumping water from the water storage tank into the ice making tank, the flow rate is adjustable;

[0031] Liquid level sensor: monitors the water level in the water tank in real time and transmits the data to the control system;

[0032] Water inlet valve: controls the water inlet according to the feedback from the liquid level sensor to ensure the water level in the water storage tank is appropriate;

[0033] Control system: Receives data from the liquid level sensor, controls the water pump flow and the opening and closing of the water inlet valve, and ensures the stability and efficiency of the ice-making process.

[0034] Based on the above ice making machine, a preferred embodiment 1 of the present invention further provides an ice making machine control method. Specifically, Figure 2 An optional flow chart of the method is shown as follows: Figure 2 As shown, the method includes the following steps S202-S206:

[0035] S202: when the liquid level sensor of the ice maker water tank fails, obtaining the liquid level data detected by the liquid level sensor for the last time;

[0036] S204: judging whether the current water storage capacity of the water storage tank meets the current ice making demand according to the liquid level data;

[0037] S206: If yes, control the ice maker to continue making ice; otherwise, control the water inlet valve of the ice maker to allow water to flow in, so as to complete the current ice making.

[0038] In the above embodiment, a control scheme is provided when the liquid level sensor of the ice maker fails. When the liquid level sensor of the water tank of the ice maker fails, the liquid level data detected by the liquid level sensor for the last time is obtained, and it is determined whether the current water storage capacity of the water tank meets the ice making demand at the time according to the liquid level data. When it meets the demand, the ice maker operates normally to ensure that the ice making process continues. When it does not meet the demand, the flow rate is controlled by the water inlet valve, and the water amount required for ice making is input to complete the ice making process at the time. Through the above control, after the liquid level sensor fails, the ice maker can continue to operate, avoiding the problem that ice cubes still remain in the ice tray after the ice maker stops after the liquid level sensor fails. When the next plate of ice is made, the remaining ice cubes need to be processed, which wastes time and reduces the ice making efficiency. The utilization rate of water is improved, the time for the next ice making is saved, and the operation efficiency of the ice maker is improved.

[0039] In a preferred embodiment of the present invention, judging whether the current water storage capacity of the water storage tank meets the current ice making demand according to the liquid level data includes: determining the current water storage capacity of the water storage tank according to the liquid level data; obtaining the remaining water required for the current ice making; judging whether the current water storage capacity is greater than the remaining water required; if so, determining that the current water storage capacity of the water storage tank meets the current ice making demand, otherwise, determining that the current water storage capacity of the water storage tank does not meet the current ice making demand. Since the last liquid level data detected by the liquid level sensor is obtained, the remaining water capacity of the water storage tank can be determined according to the data, and then the current water storage capacity of the water storage tank meets the current ice making demand according to the remaining water required for the current ice making. Preferably, considering that the time of the last liquid level data detected by the liquid level sensor is earlier than the time of the current judgment step, the ice maker has been running, so the current water storage capacity of the water storage tank obtained according to the last liquid level data detected by the liquid level sensor is greater than the current actual water storage capacity. Therefore, a threshold value can also be set. When the sum of the current water storage capacity of the water storage tank obtained according to the last liquid level data detected by the liquid level sensor plus the threshold value is greater than the remaining required water capacity, it is determined that the current water storage capacity of the water storage tank meets the current ice making demand. Otherwise, it is determined that the current water storage capacity of the water storage tank does not meet the current ice making demand. By setting a threshold value, the accuracy of the judgment result can be improved, which is convenient for subsequent ice making control.

[0040] In the ice-making process, the remaining required water volume of the current ice-making is obtained, including: obtaining the ice-making process or ice-making time of the current ice-making; determining the remaining required water volume according to the ice-making process or ice-making time. Since the ice-making process or ice-making time is closely related to the water consumption and ice production, the remaining required water volume can be determined according to the ice-making process or ice-making time. For example, if the ice-making is in the de-icing stage, the remaining required water volume is 0. In addition, the remaining required water volume can also be determined by the ice-making time. For example, if the ice-making time is half of the required ice-making time, the remaining required water volume is half of the total required water volume. Therefore, by calculating the remaining required water volume through the ice-making process or ice-making time, the remaining required water volume is accurately obtained, and then an accurate judgment result is obtained to guide the ice-making process.

[0041] When it is determined based on the liquid level data that the current water storage volume of the water storage tank does not meet the current ice making demand, the water inlet valve of the ice maker is controlled to inlet water, including: calculating the water volume difference between the remaining required water volume and the current water storage volume; controlling the water inlet valve to start inletting water until the water volume reaches the water volume difference. That is, when the current water storage volume does not meet the current ice making demand, ice making is not stopped, but the remaining required water volume is calculated to continue to supply water, which does not affect the current ice making. The ice making control scheme of the present invention can complete the current ice making when the remaining water volume meets the ice making demand or does not meet the ice making demand, reducing the loss of ice cubes that have been made when ice making is stopped when the liquid level sensor fails in the prior art, completing the current ice making process, improving the utilization rate of water, and saving the next ice making time, thereby improving the operating efficiency of the ice maker.

[0042] In addition, after controlling the ice maker to continue making ice, or controlling the water inlet valve of the ice maker to inlet water to complete the current ice making, it also includes: after completing the current ice making, controlling the ice maker to stop, and alarming the failure of the liquid level sensor. After the ice making is completed, a fault alarm is issued, that is, when the de-icing is completed, the unit is stopped, and the liquid level sensor is reported to be failed, so that the user can perform maintenance in time.

[0043] When it is determined that the current water storage does not meet the current ice-making demand, the water inlet valve of the ice-making machine is controlled to inlet water. At this time, the ice-making mode of the current ice-making is obtained; it is determined whether the water demand of the ice-making mode of the current ice-making is the ice-making mode with the minimum water demand; if so, the water inlet valve of the ice-making machine is triggered to inlet water; otherwise, it is determined whether there are other ice-making modes whose current water storage in the water tank can meet the ice-making demand. If so, the ice-making mode of the current ice-making is switched to other ice-making modes, and the ice-making machine is controlled to continue to make ice according to other ice-making modes. That is, the ice-making machine has multiple ice-making modes, and each ice-making mode requires different amounts of water. If the current ice-making mode is not the ice-making mode with the minimum water consumption, the ice-making mode can be adjusted to reduce the water demand of the ice-making mode, so as to avoid adding water to complete ice-making. If it is adjusted or already the ice-making mode with the minimum water demand, but water replenishment is still needed, the water inlet valve of the ice-making machine is controlled to inlet water. By judging and adjusting the ice-making mode, the reliability of ice-making can be further improved, and the ice-making process can be ensured to be completed smoothly.

[0044] Optionally, whether the liquid level sensor is failed is determined in the following manner: obtaining the liquid level data detected by the liquid level sensor; determining whether the liquid level data is valid; when the number of invalid liquid level data reaches a preset number of times, determining that the liquid level sensor is failed, otherwise, determining that the liquid level sensor is not failed. For example, when the liquid level sensor feeds back invalid liquid level information for five consecutive times, the liquid level sensor is determined to be failed. Through the above judgment process, not only can the state of the liquid level sensor be accurately determined, but also the control after the liquid level sensor fails can be carried out in time to avoid affecting the ice making process and user experience.

[0045] In another optional embodiment of the present invention, ice making can also be performed in the following manner: when the liquid level sensor fails, the system determines the current liquid level height, the current water storage volume meets the water volume required for the current ice making mode, the ice maker operates normally, and when defrosting is completed, the unit stops, and the liquid level sensor fails; when the current water storage volume does not meet the water volume required for the current ice making mode, the system selects a suitable current ice making mode based on the current liquid level information comparison, and when defrosting is completed, the unit stops, and the liquid level sensor fails. When the current water storage volume does not meet the water volume required for the current ice making mode, the system compares the current liquid level information, and none of the ice making modes pre-stored in the system can meet the requirement, the system selects the mode with the smallest water demand for ice making by default, and when defrosting is completed, the unit stops, and the liquid level sensor fails.

[0046] Another ice making machine control method is also provided in the preferred embodiment 1 of the present invention. Specifically, Figure 3 An optional flow chart of the method is shown as follows: Figure 3 As shown, the method includes the following steps S301-S311:

[0047] S301: Start;

[0048] S302: Liquid level sensor fails and the equipment is running;

[0049] S303: The liquid level is greater than the preset height. If so, proceed to step S308, otherwise proceed to step S304;

[0050] S304: water inlet valve control; that is, when the current water storage does not meet the current ice making demand, ice making is not stopped, but the remaining required water volume is calculated to continue water supply without affecting the current ice making;

[0051] S305: normal ice making;

[0052] S306: de-icing;

[0053] S307: warning prompt; controlling the water inlet valve of the ice maker to allow water to enter, so as to complete the ice making, control the ice maker to stop, and issue a liquid level sensor failure alarm so that the user can perform maintenance in time;

[0054] S308: normal ice making;

[0055] S309: de-icing;

[0056] S310: warning prompt; when the ice maker is controlled to continue making ice, after the current ice making is completed, the ice maker is controlled to stop and a liquid level sensor failure alarm is issued so that the user can perform maintenance in time;

[0057] S311: End.

[0058] In the above embodiment, when the liquid level sensor of the ice maker fails, the last data of the liquid level sensor is used to determine whether the current liquid meets the requirements for completing ice making. If not, the flow is controlled by the water inlet valve to input the amount of water required for ice making. If it meets the requirements, the ice maker operates normally to ensure that the ice making process continues.

[0059] Example 2

[0060] Based on the ice-making machine control method provided in the above-mentioned embodiment 1, an ice-making machine control device is further provided in a preferred embodiment 2 of the present invention. Specifically, Figure 4 An optional structural block diagram of the device is shown, such as Figure 4 As shown, the device comprises:

[0064] In the above embodiment, a control scheme is provided when the liquid level sensor of the ice maker fails. When the liquid level sensor of the water tank of the ice maker fails, the liquid level data detected by the liquid level sensor for the last time is obtained, and it is determined whether the current water storage capacity of the water tank meets the ice making demand at the time according to the liquid level data. When it meets the demand, the ice maker operates normally to ensure that the ice making process continues. When it does not meet the demand, the flow rate is controlled by the water inlet valve, and the water amount required for ice making is input to complete the ice making process at the time. Through the above control, after the liquid level sensor fails, the ice maker can continue to operate, avoiding the problem that ice cubes still remain in the ice tray after the ice maker stops after the liquid level sensor fails. When the next plate of ice is made, the remaining ice cubes need to be processed, which wastes time and reduces the ice making efficiency. The utilization rate of water is improved, the time for the next ice making is saved, and the operation efficiency of the ice maker is improved.

[0067] The control module 406 includes: a first control unit, which is used to control the water inlet valve of the ice maker, including: calculating the water volume difference between the remaining required water volume and the current water storage volume; controlling the water inlet valve to start water inlet until the water inlet reaches the water volume difference.

[0068] The control module 406 also includes: an alarm unit, which is used to control the ice maker to continue making ice, or control the water inlet valve of the ice maker to inlet water to complete the current ice making. After the current ice making is completed, the ice maker is controlled to stop and an alarm of liquid level sensor failure is issued.

[0069] The control module 406 also includes: a second control unit, which is used to control the water inlet of the water inlet valve of the ice maker, including: obtaining the ice-making mode of the current ice-making; determining whether the water demand of the ice-making mode of the current ice-making is the ice-making mode with the smallest water demand; if so, triggering the control of the water inlet valve of the ice maker to allow water to enter; otherwise, determining whether there are other ice-making modes whose current water storage capacity in the water storage tank can meet the ice-making demand, and if so, switching the ice-making mode of the current ice-making to other ice-making modes, and controlling the ice-maker to continue making ice according to other ice-making modes.

[0070] The device also includes: a detection module, which is used to obtain liquid level data detected by the liquid level sensor before the liquid level sensor of the ice maker water tank fails; determine whether the liquid level data is valid; when the number of invalid times of the liquid level data reaches a preset number, determine that the liquid level sensor has failed, otherwise, determine that the liquid level sensor has not failed.

[0071] Regarding the device in the above embodiment, the specific manner in which each unit and module performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.

[0072] Example 3

When the computer executable instructions are executed by a computer processor, they are used to execute the ice maker control method as described above.

[0081] In the above embodiment, a control scheme is provided when the liquid level sensor of the ice maker fails. When the liquid level sensor of the water tank of the ice maker fails, the liquid level data detected by the liquid level sensor for the last time is obtained, and it is determined whether the current water storage capacity of the water tank meets the ice making demand at the time according to the liquid level data.
