Description

Technical Field

[0001] The present application relates to the field of refrigerators, and particularly to a refrigerator, a refrigerator control method, and a refrigerator controller. Background Art

[0002] Currently, many high-end refrigerators on the market are equipped with an automatic ice-making function and integrate a water dispenser function; for such refrigerators integrating ice-making and water dispenser functions, water supply is generally achieved through a water tank, a water pump, and a water pipe. One way is to supply water to the ice maker to realize the ice-making function, and the other way is to supply water to the water dispenser to realize the water dispenser function.

[0003] However, some families may stop using the ice-making function and the water dispenser function after the initial experience. The water remains in the water pipe and cannot be discharged. When the water pipe is placed for a long time without use, residual water will precipitate, adhering to the inner wall of the water storage tank. Floating substances such as algae will also be generated if the residual water is left for too long, which will endanger human health when used again. Since the water pipe is generally set with a relatively long length and is an internal component and cannot be removed for cleaning, there is a problem of difficult cleaning of the water pipe.

[0049] Many high-end refrigerators are equipped with an automatic ice-making function and also integrate a water dispenser function. Therefore, currently, in a refrigerator, generally, a water tank, a water pump, and a water pipe are combined to supply water. One way supplies the ice maker, and the other way supplies the water dispenser. Among them, the water tank can be removed for free cleaning. However, since the very long water pipe is an internal component and cannot be removed for cleaning. Especially, some users may no longer use it after experiencing the water dispenser and / or ice-making function for the first time, resulting in the water flowing out of the water tank remaining in the water pipe and unable to be discharged.

[0050] Meanwhile, when the water pipe is placed for a long time without use, the residual water in the water pipe will precipitate sediment, which adheres to the inner wall of the pipe; and if the residual water is placed for too long, floating substances such as algae will also be generated, which will endanger human health when used again.

[0051] Therefore, based on the situation that it is difficult to clean the water pipe in the existing refrigerator, which will lead to the growth of bacteria and is not conducive to the user's reuse, the present application provides a refrigerator, including a water tank, an ice maker and a water dispenser. The water tank is connected to the ice maker through a first water supply pipeline, and the water tank is connected to the water dispenser through a second water supply pipeline; it further includes a third water supply pipeline; the third water supply pipeline connects the first water supply pipeline and the second water supply pipeline; a first water pump is arranged at one end of the first water supply pipeline close to the water tank, and a first water valve is arranged at one end of the first water supply pipeline close to the ice maker; a second water pump is arranged at one end of the second water supply pipeline close to the water tank, and a second water valve is arranged at one end of the second water supply pipeline close to the water dispenser; one end of the third water supply pipeline is connected to the first water supply pipeline between the first water pump and the first water valve, and the other end of the third water supply pipeline is connected to the second water supply pipeline between the second water pump and the second water valve; a third water valve is arranged on the third water supply pipeline.

[0052] Figure 1 It is a schematic diagram of the water supply device of the refrigerator provided by the embodiment of the present application. Refer to Figure 1 , the water supply device in the refrigerator 1 includes a water tank 10, an ice maker 20, a water dispenser 30, a water pump for providing power to make the water flow, and a water valve for controlling and regulating this flow. Among them, the water tank 10 is connected to the ice maker 20 to form a first water supply pipeline A, and the water tank 10 is connected to the water dispenser 30 to form a second water supply pipeline B. At the same time, a third water supply pipeline C connecting the first water supply pipeline A and the second water supply pipeline B is also provided; a first water pump 41 is arranged at one end of the first water supply pipeline A close to the water tank 10, and a second water pump 42 is arranged at one end of the second water supply pipeline B close to the water tank 10; through the first water pump 41 and the second water pump 42, the water stored in the water tank 10 flows through the first water supply pipeline A and the second water supply pipeline B respectively, and then is transported to the ice maker 20 and the water dispenser 30.

[0053] A first water valve 51 is provided at one end of the first water supply pipeline A close to the ice maker 20, and a second water valve 52 is provided at one end of the second water supply pipeline B close to the water dispenser 30; by opening or closing the first water valve 51 / second water valve 52, the water flow to the ice maker 20 / water dispenser 30 can be conveniently controlled. If the ice maker 20 / water dispenser 30 malfunctions or needs to be cleaned and maintained, closing the first water valve 51 / second water valve 52 can prevent water from continuing to flow into the ice maker 20 / water dispenser 30, thereby avoiding possible water damage or other mechanical failures. At the same time, in some cases, the first water valve 51 can adjust the water volume entering the ice maker 20 to optimize the ice-making efficiency or quality, and the second water valve 52 can adjust the water volume and speed entering the water dispenser 30.

[0054] Further, based on the first water supply pipeline A and the second water supply pipeline B, a third water supply pipeline C connecting the first water supply pipeline A and the second water supply pipeline B is provided, and a third water valve 53 is provided on the third water supply pipeline C.

[0055] When the ice-making button action is detected, first, the first water pump 41 and the first water valve 51 are opened, and the water in the water tank 10 is circulated through the first water supply pipeline A to the inlet of the ice maker 20 for ice making; when the ice-making button action is not detected, that is, when it is necessary to end the water supply to the ice maker 20, the first water valve 51 and the first water pump 41 are closed, and the second water pump 42 is opened in the reverse direction. At the same time, the third water valve 53 is opened, so that the residual water in the first water supply pipeline A passes through the third water supply pipeline C, flows reversely through the second water supply pipeline B, and returns to the water tank 10 through the reverse second water pump 42. Thus, the residual water in the first water supply pipeline A is discharged, and further the water pipe scale and bacteria growth are reduced. In some of these embodiments, due to the long-term non-cleaning of the water pipes, sediment and the like will appear on the inner wall of the water pipes, which will endanger the health of users when used again. At the same time, when a certain water pipe is blocked, this water pipe cannot supply water. Since the water tank is generally in the refrigerating chamber and the ice maker and the water dispenser are in the freezing chamber, when laying the water pipes, it is necessary to pass through the freezing door body, and it is very easy to be frozen at a low temperature due to improper installation, resulting in the temperature of the water pipe close to the inner liner of the door being too low. Or due to the abnormal operation of the water pump, the water supply cannot be provided.

[0056] To solve the above problems, in the embodiments of the present application, a refrigerator control method is provided, and this method is applied to the refrigerator provided in the embodiments of the present application. Figure 2 It is the flowchart of the refrigerator control method provided by the embodiments of the present application. Refer to Figure 2 and this control method includes:

[0057] Step S210, by responding to the received water pipe cleaning instruction, closing the first water valve and the second water valve, and opening the third water valve.

[0058] Among them, when the water pipe needs to be cleaned, the refrigerator controller receives a water pipe cleaning instruction. This water pipe cleaning instruction can be received regularly according to the historical cleaning cycle or sent by the refrigerator user, and no specific limitation is made here. Subsequently, the refrigerator controller responds to the received water pipe cleaning instruction and controls the closing of the first water valve and the second water valve. Since the first water valve and the second water valve are respectively arranged near one end of the ice maker and the water dispenser, when the first water valve and the second water valve are closed and the third water valve is opened, a cleaning circuit including the first water supply pipeline A, the second water supply pipeline B, and the third water supply pipeline C will be formed in the entire refrigerator water supply device, realizing that when cleaning the water pipe, the first water supply pipeline A and the second water supply pipeline B can be completely and thoroughly cleaned.

[0059] Step S220, pulse-start the first water pump and the second water pump; the rotation directions of the first water pump and the second water pump are opposite; after a preset time, turn off the first water pump and the second water pump.

[0060] Among them, while closing the first water valve and the second water valve and opening the third water valve, pulse-start the first water pump and the second water pump, and control the rotation directions of the first water pump and the second water pump to be opposite, so that the water in the water tank can circulate in the cleaning circuit including the first water supply pipeline A, the second water supply pipeline B, and the third water supply pipeline C, achieving the effect of cleaning the water pipe. When the time for pulse-starting the first water pump and the second water pump reaches the preset time, it indicates that the water pipes in the cleaning circuit including the first water supply pipeline A, the second water supply pipeline B, and the third water supply pipeline C have been cleaned, and at this time, turn off the first water pump and the second water pump. Further, remove and clean the water tank, and add an appropriate amount of clean water to the water tank before the next use.

[0061] Through the above steps, a third water supply pipeline with a third water valve is connected between the first water supply pipeline (ice maker water supply pipeline) and the second water supply pipeline (water dispenser water supply pipeline). By controlling the closing of the first water valve and the second water valve and opening the third water valve, a cleaning circuit including the first water supply pipeline and the second water supply pipeline is formed; at the same time, by pulse-starting the water pumps in the two water supply pipelines, one rotates forward and the other rotates backward, thereby achieving the effect of flushing the water pipes in the two water supply pipelines with a large amount of water.

[0062] In some of the embodiments, applied to the above-mentioned refrigerator, a method for discharging the residual water in the water pipe is also provided. Figure 3 It is a flowchart of another refrigerator control method provided by the embodiments of the present application. This refrigerator control method further includes:

[0063] Step S310, in response to the received drinking water instruction, open the second water valve and the second water pump to supply water to the water dispenser.

[0064] Among them, when a drinking water instruction is received, that is, when the refrigerator controller detects the action of the drinking water button, the second water pump and the second water valve are first turned on, and the water in the water tank is circulated through the second water supply pipeline B to the entrance of the drinking fountain to supply water to the drinking fountain.

[0065] Step S320, in response to the received cancel drinking water instruction, close the second water valve, open the third water valve, and turn on the first water pump with a rotation direction opposite to that of the second water pump to drain the residual water in the second water supply pipeline into the water tank.

[0066] Among them, when the received cancel drinking water instruction is received, that is, when the refrigerator controller fails to detect the action of the drinking water button, it is necessary to end the water supply to the ice maker at this time. The refrigerator controller closes the first water valve and the first water pump, and reversely opens the second water pump. At the same time, the third water valve is opened, so that the residual water in the second water supply pipeline B flows through the third water supply pipeline C, reversely flows through the first water supply pipeline A, and flows back to the water tank through the reverse first water pump. Thus, the residual water in the second water supply pipeline B is drained, and further the water pipe scale and bacteria growth are reduced.

[0067] In some of these embodiments, the method further includes: in response to the received ice making instruction, turn on the first water valve and the first water pump to supply water to the ice maker; in response to the received cancel ice making instruction, close the first water valve, open the third water valve, and control to turn on the second water pump with a rotation direction opposite to that of the first water pump to drain the residual water in the first water supply pipeline into the water tank.

[0068] Among them, when the ice making instruction is received, that is, when the action of the ice making button is detected, the refrigerator controller first turns on the first water pump and the first water valve, and the water in the water tank is circulated through the first water supply pipeline A to the entrance of the ice maker to make ice; when the cancel ice making instruction is received, that is, when the refrigerator controller fails to detect the action of the ice making button, it is necessary to end the water supply to the ice maker at this time, close the first water valve and the first water pump, and reversely open the second water pump. At the same time, the third water valve is opened, so that the residual water in the first water supply pipeline A flows through the third water supply pipeline C, reversely flows through the second water supply pipeline B, and flows back to the water tank through the reverse second water pump. Thus, the residual water in the first water supply pipeline A is drained, and further the water pipe scale and bacteria growth are reduced.

[0069] In some of these embodiments, current detection modules are both provided in the first water pump and the second water pump for respectively detecting the working current when the first water pump and the second water pump are working. The refrigerator further includes a display screen; Figure 4 is the flowchart of the abnormal water supply processing method provided by the embodiment of the present application. As Figure 4 shown, the abnormal water supply processing method further includes:

[0070] Step S410: Determine whether the operating currents of the first water pump and the second water pump exceed a preset first current threshold range to obtain a current determination result.

[0071] Among them, during the use of the water supply pipeline of the refrigerator, various types of abnormal conditions may occur. Therefore, when performing abnormal handling, it is necessary to first determine the type of abnormality of the water supply pipeline. In the embodiments of the present application, it is mainly determined by the current detection modules provided in the first water pump and the second water pump, and based on the operating currents of the first water pump and the second water pump detected by the current detection modules, combined with the preset first current threshold. The preset first current threshold can be determined according to the historical operating current of the water pump or the power state of the current refrigerator, etc., and no specific limitation is made here.

[0072] Step S420: Based on the current determination result, perform an abnormal operation on the water supply pipeline.

[0073] Among them, after obtaining the current determination result, determine the type of abnormality of the water supply pipeline according to the current determination result, and trigger a water supply pipeline adjustment instruction matching the type of abnormality of the water supply pipeline. Performing an abnormal operation on the water supply pipeline based on this power supply pipeline adjustment instruction can quickly identify and handle the type of abnormality, and further improve the efficiency of abnormal handling of the refrigerator water pipe.

[0074] Through the above steps, in the embodiments of the present application, the situation of abnormal water supply pipeline is considered, and by judging the operating currents of the first water pump and the second water pump, the corresponding type of abnormality of the water supply pipeline is determined. Based on the type of abnormality of the water supply pipeline, a water supply pipeline adjustment instruction matching the type of abnormality of the water supply pipeline is triggered, thereby improving the efficiency of abnormal handling of the water supply pipeline.

[0075] In some of these embodiments, performing an abnormal operation on the water supply pipeline based on the current determination result further includes: when it is determined that the operating current of the first water pump and / or the second water pump does not exceed the preset first current threshold range, sending a water pump abnormal signal to the display screen for abnormal warning display.

[0076] When it is determined that the operating current of the first water pump exceeds the preset first current threshold range but does not exceed the preset second current threshold range, and the operating current of the second water pump exceeds the preset second current threshold range, close the second water valve and the first water pump, and open the second water pump, the first water valve, and the third water valve; supply water to the ice maker through the second water supply pipeline.

[0077] When it is determined that the operating current of the second water pump during operation exceeds the preset first current threshold range but does not exceed the preset second current threshold range, and the operating current of the first water pump during operation exceeds the preset second current threshold range, a second adjustment instruction is triggered; the water supply pipeline adjustment instruction includes the second adjustment instruction; according to the second adjustment instruction, the first water valve and the second water pump are closed, and the first water pump, the second water valve, and the third water valve are opened; water is supplied to the drinking machine through the first water supply pipeline; the second current threshold range is greater than the first current threshold range.

[0078] Among them, when it is determined that the operating current of the first water pump and / or the second water pump during operation does not exceed the preset first current threshold range, it indicates that the first water pump and / or the second water pump is damaged. Then, a first adjustment instruction is directly triggered, and based on the first adjustment instruction, a water pump abnormal signal is sent to the display screen for abnormal warning display. Specifically, when the operating current of the first water pump and / or the second water pump during operation does not exceed the preset first current threshold range, at this time, the operating current of the first water pump and / or the second water pump is zero, indicating that the water pump is damaged and relevant personnel need to be informed for repair and replacement.

[0079] Among them, when it is determined that the operating current of the first water pump or the second water pump during operation exceeds the preset first current threshold range but does not exceed the preset second current threshold range, and the operating current of the second water pump or the first water pump during operation exceeds the preset second current threshold range, a second adjustment instruction is triggered. At this time, it indicates that there is an abnormality in the first water supply pipeline or the second water supply pipeline corresponding to the first water pump or the second water pump.

[0080] Specifically, when the operating current of the second water pump during operation exceeds the preset first current threshold range but does not exceed the preset second current threshold range, and the operating current of the first water pump exceeds the preset second current threshold range, it indicates that there is an abnormality in the second water supply pipeline corresponding to the second water pump, that is, there is an abnormality in the drinking water circuit, and the first water supply pipeline corresponding to the first water pump, that is, the ice-making water circuit, is normal. At this time, the first water valve and the second water pump are closed, and the first water pump, the second water valve, and the third water valve are opened, so that the water supply water flow path for supplying water to the drinking machine is in turn: water tank, first water pump, first water supply pipeline, third water supply pipeline (third water valve), second water valve, drinking machine, that is, the drinking machine is normally supplied with water through the third water supply pipeline.

[0081] In some of these embodiments, when the operating current of the first water pump during operation exceeds the preset first current threshold range but does not exceed the preset second current threshold range, and the operating current of the second water pump during operation exceeds the preset second current threshold range, it indicates that there is an abnormality in the first water supply pipeline corresponding to the first water pump, that is, an abnormality in the ice-making water circuit, and the second water supply pipeline corresponding to the second water pump, namely the drinking water circuit, is normal. At this time, close the second water valve and the first water pump, and turn on the second water pump, the first water valve, and the third water valve, so that the water supply path for supplying water to the ice maker is as follows: water tank, second water pump, second water supply pipeline, third water supply pipeline (third water valve), first water valve, water dispenser, that is, the water dispenser is normally supplied with water through the third water supply pipeline.

[0082] In some of these embodiments, based on the current judgment result, performing the abnormal operation of the water supply pipeline further includes: when it is judged that the operating currents of both the first water pump and the second water pump during operation exceed the preset first current threshold range and do not exceed the preset second current threshold range, triggering a third adjustment instruction; the water supply pipeline adjustment instruction includes the third adjustment instruction; according to the third adjustment instruction, close the first water valve and the second water valve, and turn on the first water pump and the second water pump whose rotation direction is opposite to that of the first water pump; when the preset first water pump opening time is reached, update the rotation directions of the first water pump and the second water pump; when the operating time of the first water pump and the second water pump after updating the rotation direction reaches the preset second water pump opening time, send a signal for replacing the hot water in the water tank to the client.

[0083] Among them, when it is judged that the operating currents of both the first water pump and the second water pump during operation exceed the preset first current threshold range and do not exceed the preset second current threshold range, that is, when it is detected that both the drinking water circuit and the ice-making water circuit are abnormal, considering that there is a fine filter screen at the water inlet of the water circuit, the abnormal type that occurs in the water supply pipeline is basically ice blockage. At this time, it is necessary to close the first water valve and the second water valve, and turn on the first water pump and the second water pump whose rotation direction is opposite to that of the first water pump. After the preset first water pump opening time is reached, update the rotation directions of the first water pump and the second water pump to make the water flow in the water tank continuously impact the ice blockage point. When the working time for impacting the ice blockage point reaches the preset second water pump opening time, it indicates that the ice blockage point is difficult to eliminate and hot water needs to be used for impact, that is, send a signal for replacing the hot water in the water tank to the client.

[0084] Further, when the client receives the signal for replacing hot water, send a signal for confirming the replacement of hot water to the refrigerator controller. At this time, repeat the operation of closing the first water valve and the second water valve, and turning on the first water pump and the second water pump whose rotation direction is opposite to that of the first water pump. After the preset first water pump opening time is reached, update the rotation directions of the first water pump and the second water pump to make the water flow in the water tank continuously impact the ice blockage point.

[0085] In some of these embodiments, after updating the rotation directions of the first water pump and the second water pump, it further includes: when the operating times of the first water pump and the second water pump after updating the rotation directions have not reached a preset second water pump start time, detecting the total operating current when the first water pump and the second water pump are operating; determining whether the total operating current exceeds a preset third current threshold range; when the total operating current exceeds the preset third current threshold range, sending a repair success signal to the client.

[0086] In some of these embodiments, after determining whether the total operating current exceeds a preset third current threshold range, it includes: when the total operating current does not exceed the preset third current threshold range, controlling to close the first water valve and the second water valve, controlling to start the first water pump and the second water pump with a rotation direction opposite to that of the first water pump; when the preset first water pump start time is reached, controlling to update the rotation directions of the first water pump and the second water pump.

[0087] Wherein, when it is determined that the operating currents of both the first water pump and the second water pump exceed a preset first current threshold range and do not exceed a preset second current threshold range, that is, after it is detected that both the drinking water circuit and the ice making circuit are abnormal, closing the first water valve and the second water valve, and starting the first water pump and the second water pump with a rotation direction opposite to that of the first water pump, and after reaching the preset first water pump start time, updating the rotation directions of the first water pump and the second water pump so that the water flow in the water tank continuously impacts the ice blockage point.

[0088] However, when the time for impacting the ice blockage point is relatively long but still has not reached the preset second water pump start time, it is necessary to detect the operating current of the corresponding water pump every time the water pump is started in the forward direction. When the total operating current of the first water pump and the second water pump exceeds the preset third current threshold range, it indicates that the ice blockage has disappeared, that is, the water supply circuit has been repaired successfully and can be used normally.

[0089] Further, when the total operating current of the first water pump and the second water pump does not exceed the preset third current threshold range, at this time, it is necessary to repeat the operation of closing the first water valve and the second water valve, starting the first water pump and the second water pump with a rotation direction opposite to that of the first water pump, and after reaching the preset first water pump start time, updating the rotation directions of the first water pump and the second water pump so that the water flow in the water tank continuously impacts the ice blockage point, until the total operating current of the first water pump and the second water pump exceeds the preset third current threshold range, indicating that the repair program is completed and the water supply pipeline can be used normally.

[0093] In one specific embodiment, when the water supply pipeline of the refrigerator supplies water abnormally,

[0094] In this specific embodiment, an abnormal water supply solution method is provided, and the process includes the following steps:

[0095] S1, sense the working current of the first water pump and the second water pump when they are working through the current detection module.

[0096] Among them, the current detection module is specifically a water pump current detection circuit. If the working current of the water pump is zero, step S2 is executed; if the initial current of a single water pump is greater than a preset first current threshold, step S3 is executed; if the initial currents of both water pumps are greater than the preset first current threshold, step S4 is executed; if the working current of the water pump is greater than a preset second current threshold, it indicates that the first water pump and the second water pump are working normally, and the program ends. Exemplarily, the preset first current threshold is set to 1, and the preset second current threshold is set to 2.

[0097] S2, the display screen prompts that the water pump is damaged. Among them, when the initial current of a single water pump is greater than the preset first current threshold, it indicates that the water pump is damaged. At this time, an abnormal signal of the water pump needs to be sent to the display screen for abnormal warning display, so that relevant personnel can replace the water pump.

[0098] S3, when an abnormality is detected in the drinking water pipeline, close the first water valve and the second water pump, and open the first water pump, the second water valve, and the third water valve. Specifically, by opening or closing the above-mentioned water valves and water pumps, normal water supply to the water dispenser can be achieved through the third water supply pipeline. When an abnormality is detected in the ice-making pipeline, it is implemented in the same way. For specific methods, reference can be made to the methods in the above embodiments, and no specific description will be given here.

[0099] S4, when abnormalities are detected simultaneously in the drinking water pipeline and the ice-making pipeline, make the water in the water tank continuously impact the ice blockage point. Specifically, the drinking water pipeline here is the second water supply pipeline in the foregoing embodiment, and the ice-making pipeline here is the first water supply pipeline in the foregoing embodiment. When abnormalities are detected simultaneously in the drinking water pipeline and the ice-making pipeline, considering that there is a fine filter screen at the water inlet of the pipeline, it is basically ice blockage.

[0100] At this time, it is necessary to close the first water valve and the second water valve, while opening the third water valve, and turn on the second water pump in the forward direction and the first water pump in the reverse direction, and keep this state for 5 seconds. Then turn on the first water pump in the reverse direction and the second water pump in the forward direction, and keep this state for 5 seconds. The forward and reverse directions of the water pumps are continuously updated, so that the water flow in the water tank continuously impacts the ice blockage point, and start the timer to record the working time T0 of the first water pump and the second water pump. Then judge whether the working time T0 of the first water pump and the second water pump is greater than the preset opening time of the second water pump, which is 45 minutes. When the working time T0 of the first water pump and the second water pump is greater than the preset opening time of the second water pump, which is 45 minutes, prompt the user to replace the water in the water tank with hot water. Then after the user confirms, repeat closing the first water valve and the second water valve, while opening the third water valve, and turn on the second water pump in the forward direction and the first water pump in the reverse direction, and keep this state for 5 seconds. Then turn on the first water pump in the reverse direction and the second water pump in the forward direction, and keep this state for 5 seconds. The forward and reverse directions of the water pumps are continuously updated, so that the water flow in the water tank continuously impacts the ice blockage point. When the working time T0 of the first water pump and the second water pump is not greater than the preset opening time of the second water pump, which is 45 minutes, every time the water pump is turned on in the forward direction for 1 minute, detect the working current of the water pump correspondingly. If the current working currents of both water pumps are greater than the preset third current threshold range, then prompt the user that the water circuit has been repaired and can be used normally. Otherwise, repeat closing the first water valve and the second water valve, while opening the third water valve, and turn on the second water pump in the forward direction and the first water pump in the reverse direction, and keep this state for 5 seconds. Then turn on the first water pump in the reverse direction and the second water pump in the forward direction, and keep this state for 5 seconds. The forward and reverse directions of the water pumps are continuously updated, so that the water flow in the water tank continuously impacts the ice blockage point until the current working currents of both water pumps are greater than the preset third current threshold range. Thus, the repair program ends.
