Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The embodiment of the application provides an abnormality detection method of an ice maker, which can be an independent ice maker or an ice maker configured in a refrigerator. Referring to fig. 1, fig. 1 is a flowchart of an anomaly detection method of an ice maker according to an embodiment of the present application. The ice maker comprises an ice crushing assembly, the ice crushing assembly comprises an ice crushing motor and an ice crushing knife which are connected with each other, and the ice crushing motor is used for driving the ice crushing knife to rotate so as to push ice cubes out of the ice crushing chamber in a whole ice or crushed ice mode. The abnormality detection method of the ice maker is performed by, for example, a processor of the ice maker, and includes the following steps S101 to S103:
step S101: controlling the ice crushing motor to rotate according to a preset rotation program, and acquiring the rotation speed acceleration of the ice crushing motor in the rotation speed lifting process;
it should be noted that the preset rotation program is pre-stored in the memory of the ice maker and executed by the processor. Illustratively, the preset rotation program includes the following:
controlling the ice crushing motor to rotate clockwise for a first preset time period and then stopping the ice crushing motor;
and controlling the ice crushing motor to rotate anticlockwise for a second preset time period and then stopping the ice crushing motor.
The first preset time length and the second preset time length are determined according to the specific model of the ice crushing motor. The first preset duration and the second preset duration are 30-60 seconds. When the ice crushing motor rotates clockwise, the processor acquires a first rotational speed acceleration of the ice crushing motor in the rotational speed lifting process at least once; when the ice crushing motor rotates anticlockwise, the processor acquires a second rotating speed acceleration of the ice crushing motor in the rotating speed lifting process at least once; and the processor is used for judging whether the ice crushing assembly is abnormal or not according to the first rotational speed acceleration and the second rotational speed acceleration.
It can be appreciated that there is sometimes no abnormality in the ice crushing assembly itself, but there may be some fluctuation in rotational speed and acceleration of the ice crushing motor due to external factors such as unstable current. In order to avoid the situation that the ice crushing assembly is abnormally measured by mistake, the rotational speed and the acceleration of the ice crushing motor can be acquired for multiple times within a first preset time length and a second preset time length, and a final rotational speed and acceleration value is obtained according to the multiple rotational speed and acceleration values and is used for subsequent judgment. For example, the average acceleration value may be obtained by removing the maximum value and the minimum value of the plurality of rotational speed acceleration values, and one value with the largest occurrence number of the plurality of rotational speed accelerations may be taken as the final rotational speed acceleration value.
In some embodiments, an acceleration sensor is disposed on the ice crushing motor, and is configured to detect a rotational speed acceleration of the ice crushing motor, and send a corresponding feedback signal to the processor according to the rotational speed acceleration of the ice crushing motor in a rotational speed lifting process, so that the processor performs subsequent judgment according to the feedback signal. For example, if the rotational speed acceleration of the ice crushing motor in the rotational speed increasing process reaches a first preset value, a feedback signal with a flag bit of 1 is sent out, otherwise, a feedback signal with a flag bit of 0 is sent out.
Step S102: judging whether the rotational speed acceleration reaches a first preset acceleration or not;
it should be noted that, the first preset acceleration is determined according to a specific model of the ice crushing motor, and the rotational speed and the acceleration of the ice crushing motor can reach at least the first preset acceleration under the condition that the ice crushing assembly works normally. When the rotational speed and the acceleration of the ice crushing motor can not reach the first preset acceleration, the problems of freezing of the ice crushing assembly at the part, excessive icing on the surface of the ice crushing cutter or circuit and mechanical structure inside the ice crushing assembly can be solved.
For example, if the processor obtains the first rotational speed acceleration when the ice crushing motor rotates clockwise and the second rotational speed acceleration when the ice crushing motor rotates counterclockwise, respectively, it is determined whether the first rotational speed acceleration reaches the first preset acceleration and whether the second rotational speed acceleration reaches the first preset acceleration. And if any one of the first rotational speed acceleration and the second rotational speed acceleration does not reach the first preset acceleration, confirming that the ice crushing assembly is abnormal.
Step S103: and if the rotational speed acceleration does not reach the first preset acceleration, confirming that the ice crushing assembly is abnormal.
It will be appreciated that when the anomaly of some ice crushing assemblies is not severe, the rotational speed of the ice crushing motor may eventually reach a preset rotational speed, and the ice crushing blade may also normally reach the corresponding position. Therefore, if the broken ice component is judged to be faulty only according to the rotating speed of the broken ice motor, the abnormal condition cannot be detected before the abnormality of the broken ice component becomes serious so as to repair, and finally, the broken ice component cannot be automatically repaired or the manual repair difficulty is high, so that the maintenance cost of the ice machine is increased.
According to the abnormality detection method for the ice maker, whether the ice crushing assembly is abnormal or not is judged by detecting whether the rotational speed acceleration of the ice crushing motor in the speed lifting process reaches the first preset speed or not, potential abnormal conditions of the ice crushing assembly can be detected in advance, and the abnormal severity is avoided, so that the maintenance cost is increased.
In some embodiments, after confirming that the crushed ice assembly is abnormal, the processor further controls the ice maker to perform a preset repair procedure to attempt to repair the crushed ice assembly. Referring to fig. 2, fig. 2 is a flowchart of an automatic repairing method of an ice maker according to an embodiment of the present application. The vicinity of the crushed ice assembly is provided with a heating device, for example, and the automatic restoration method includes the following steps S201 to S204:
step S201: acquiring the temperature T1 of the ice crushing assembly;
illustratively, a temperature sensor is utilized to obtain the temperature of the ice blade and/or the ice crushing motor surface. It will be appreciated that when the temperature of the surface of the ice blade and/or motor is too low, it may be that the blade and/or motor freezes or the surface freezes.
Step S202: judging whether the temperature T1 of the ice crushing assembly is lower than a first preset temperature T0 or not;
it should be noted that the first preset temperature is determined according to actual needs, and is, for example, a temperature of 0 ℃ or lower than 0 ℃. When the temperature of the ice crushing assembly is lower than the first preset temperature, the condition that more ice is formed on the surface of the ice crushing assembly or the ice crushing blade is frozen with the inner wall of the ice crushing chamber can be indicated.
If the temperature of the ice crushing assembly is lower than the first preset temperature, the following step S203 is performed, otherwise, step S204 is performed.
Step S203: the heating device is started until the temperature of the ice crushing assembly is increased to a second preset temperature.
It should be noted that the first preset temperature is determined according to actual needs, for example, higher than 0 ℃. When the temperature of the ice crushing assembly is increased to the second preset temperature, for example, the ice on the surface of the ice crushing assembly is melted completely, so that the normal operation of the ice crushing assembly is not affected.
Step S204: and controlling the ice crushing motor to alternately rotate forward and backward.
It can be appreciated that when ice is jammed between the ice crushing blades, the rotational speed and the acceleration of the ice crushing motor can be influenced, and the jammed ice can be pushed out of the ice crushing chamber by controlling the ice crushing motor to alternately rotate forward and backward, so that the ice crushing assembly can work normally.
Illustratively, controlling the ice crushing motor to alternately rotate forward and backward may include the steps of:
s1: controlling the ice crushing motor to start and stop after rotating forward for 2 seconds;
s2: after stopping rotating for 0.2 seconds, controlling the ice crushing motor to rotate reversely for 20 degrees and stopping;
s3: after stopping rotating for 1 second, controlling the ice crushing motor to rotate reversely for 2 seconds and stopping;
s4: and after stopping rotating for 0.2 seconds, controlling the ice crushing motor to rotate forward for 20 degrees and stopping the ice crushing motor.
In some embodiments, for example, the crushed ice motor is controlled to stop for a plurality of times, for example four times, according to steps S1-S4, and then repair is finished.
In some embodiments, after the repair procedure of the ice machine is completed, for example, whether the crushed ice component is recovered to normal or not is detected, if the crushed ice component is not recovered to normal, an abnormal prompt is sent out, so that a user can find out and find out the repair personnel in time to solve the problem. The way to detect whether the crushed ice assembly is restored is to detect whether the rotational speed and the acceleration of the crushed ice motor can reach the first preset acceleration.
In some embodiments, referring to fig. 3, fig. 3 is a second flowchart of an anomaly detection method for an ice maker according to an embodiment of the present application. The abnormality detection method of the ice maker includes the following steps S301 to S308:
step S301: controlling the ice crushing motor to start rotating according to a preset rotating program;
it will be appreciated that each rotation of the ice crushing motor includes a first rotational speed ramp-up phase, an intermediate rotational speed stabilization phase, and a final deceleration phase.
Step S302: judging whether the ice crushing motor is in a rotating speed lifting stage or not;
if the ice crushing motor is in the rotation speed increasing stage, the following steps S303-S304 are executed, otherwise the following steps S305-S306 are executed.
Step S303: acquiring the rotating speed acceleration a of the ice crushing motor;
step S304: judging whether the rotational speed acceleration a is smaller than a first preset acceleration a1 or not;
if the rotational speed acceleration a is smaller than the first preset acceleration a1, confirming that the ice crushing assembly is abnormal, otherwise, returning to the step S302.
Step S305: monitoring the rotating speed of the ice crushing motor;
the ice crushing motor is provided with a rotation speed detecting device such as a photoelectric encoder or a Hall sensor for detecting the rotation speed of the motor.
Step S306: judging whether the highest rotating speed Rm of the ice crushing motor is greater than or equal to a first preset rotating speed R1 or not;
the first preset rotational speed is determined, for example, according to a model of the ice crushing motor, and the ice crushing motor can at least reach the first preset rotational speed, for example, when the ice crushing motor is operating normally.
If the maximum rotation speed Rm of the ice crushing motor fails to reach the first preset rotation speed R1, it is confirmed that the ice crushing assembly is abnormal, otherwise, the following step S307 is performed.
Step S307: when the shaft body of the ice crushing blade rotates to a preset initial position, acquiring the blade position of the ice crushing blade;
the ice crushing cutter comprises a shaft body and a blade, and the ice crushing motor is used for rotating the shaft body to drive the blade to rotate. The position of the shaft and blade may be detected by hall sensors or photoelectric encoders, for example. It will be appreciated that the relative position of the shaft will not generally change due to deformation or the like, whereas the blades have long been used to break hard ice cubes and are relatively prone to mechanical problems such as deformation. Therefore, by looking at the position of the shaft body as a reference and observing whether the blade is in the normal position, it is possible to determine whether the blade has a problem of deformation.
Step S308: judging whether the blade is at a first preset position or not;
if the blade is not at the first preset position, confirming that the ice crushing blade is abnormal, otherwise, ending the detection flow. It will be appreciated that the detection of whether the ice crushing blade is deformed may be before starting rotation or after ending rotation during rotation of the ice crushing motor, and the above detection method is only one embodiment.
In some embodiments, to avoid the abnormal position of the blade caused by the deformation of the shaft body relative to the motor, the ice crushing motor may be rotated to an initial state before the ice crushing motor rotates according to a preset rotation program, and it may be determined whether the shaft body is at the preset initial position, and if the shaft body is not at the preset initial position, the ice crushing blade abnormality may be confirmed and an indication of the ice crushing blade abnormality may be immediately sent.
According to the abnormality detection method for the ice maker, in the speed increasing stage of the ice crushing motor, whether the rotational speed acceleration of the ice crushing motor reaches the first preset acceleration is detected, so that potential abnormality of the ice crushing motor is detected before the abnormality problem of the ice crushing motor is serious. And if the rotational speed acceleration of the ice crushing motor is not abnormal, detecting whether the rotational speed of the ice crushing motor can reach the normal rotational speed to judge whether the rotational speed is abnormal or not, and detecting the position of the ice crushing blade to judge whether the ice crushing blade is abnormal or not, so that the abnormality of the ice crushing assembly can be detected more comprehensively and accurately, serious faults of the ice machine are avoided, the maintenance cost is increased, and the influence on the use experience of users is avoided.
