Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below in conjunction with the detailed description of the present application and the corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, are intended to fall within the scope of the present application.
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present application and are not to be construed as limiting the present application.
As shown in fig. 1, a flow chart of a first embodiment of a method for controlling ice blockage of a refrigerator fan provided by the application specifically includes the following steps:
s11: repeatedly switching on and off the fan after judging that the fan is in an abnormal state;
s12: if the repeated opening times of the fan reach the first maximum trial opening times and are still in an abnormal operation state, starting the defrosting heating device until the temperature reaches the first forced defrosting stop temperature;
s13: repeatedly switching on and off the fan again after defrosting is stopped;
s14: if the fan is still in an abnormal operation state after the repeated starting times of the fan in the repeated switching process reaches the second maximum trial starting times, starting the defrosting heating device until the temperature reaches the second forced defrosting stop temperature;
the steps will be specifically described below.
S11: and repeatedly switching on and switching off the fan after judging that the fan is in an abnormal state.
Specifically, whether the rotating speed of the fan is abnormal or not can be judged by collecting the real-time rotating speed of the fan or collecting the average rotating speed of the fan in a period of time, and then whether the fan is ice-blocked or not is judged. In addition, the temperature of the fan can be collected through the temperature sensing device to judge whether ice blockage occurs.
Further, as shown in fig. 2, the fan that repeatedly switches specifically includes:
s111: and starting the fan at the maximum rotating speed, and judging whether the rotating speed of the fan is smaller than the maximum rotating speed after the first test starting time.
S112: if not, carrying out a normal operation flow, if so, detecting and judging whether the opening times of the fan are smaller than the preset first maximum trial opening times;
s113: if yes, the fan is turned off until the first pause time, the steps are repeated, and if not, the follow-up steps are carried out.
Here, the fan is started at the maximum rotation speed, so that the fan is started at the maximum rotation speed when light micro ice blockage occurs or in a critical state, broken ice blocking fan blades can be removed in a physical mode by utilizing the rotation of the fan, the success of one-time starting is ensured as much as possible, and the effect of improving efficiency is achieved.
In other embodiments of the present application, it may be configured that the fan is started at a low rotation speed, and the fan is gradually adjusted to a maximum rotation speed in the first fan test start procedure repeatedly, and the protection effect on the fan may be achieved by setting a gradually increased rotation speed.
By repeatedly and intermittently turning on the fan under certain condition parameters, on one hand, broken ice can be tried to be opened through the rotation of the fan; on the other hand, whether the fan is normal or not can be comprehensively judged by collecting the rotating speed data of the fan for a plurality of times and utilizing the rotating speed or the average rotating speed for a plurality of times, so that erroneous judgment is avoided.
Illustratively, the first test on time is 10 seconds. The fan is started at the maximum rotating speed, and then whether the rotating speed reaches the maximum rotating speed is detected, so that the fan can keep a stable running state when the speed is measured, the first test starting time is set to be shorter, and the fan can be prevented from being started at the maximum rotating speed to generate heat under the condition of ice blockage, and the service life of the fan is influenced.
Illustratively, the first pause time is 2 minutes. After the fan is started for the first test starting time, the fan is closed until the first pause time is reached, and then the fan is started repeatedly, so that the blocked fan can be prevented from generating too much heat due to the excessively high starting frequency, and the fan is further protected.
The first maximum number of test starts is 10, for example. In the first fan test opening process, through the test opening of more times, under the condition of not defrosting and heating, the physical type ice breaking can be tried for a plurality of times, so that the process time and the energy consumption are reduced as much as possible, and in the first ice blockage solving process, the accuracy of data can be ensured through the fan rotating speed acquired for more times.
Of course, in other embodiments, the first test opening time, the first pause time and the first maximum test opening frequency may be specifically adjusted according to parameters of different types of refrigerators.
S121: after the repeated opening times of the fan reach the first maximum trial opening times, judging whether the fan is still in an abnormal operation state or not;
s122: if yes, starting the defrosting heating device until the temperature reaches the first forced defrosting stop temperature, and if not, performing a normal operation flow.
Further, the stopping conditions of the defrosting heating device further include: and the starting time of the defrosting heating device reaches the preset defrosting heating time.
The defrosting heating device can be a resistance wire or the like.
Here, through setting up two kinds of stopping modes of time cut-off and temperature cut-off, can reduce the energy consumption to avoid defrosting heating device high temperature and cause the damage to each part.
Illustratively, the first defrosting heating stop time is 30 minutes and the first defrosting heating stop temperature is 12 degrees. The first defrosting heating stop temperature is set to be a lower temperature to try to solve ice blockage, so that energy consumption can be reduced.
Of course, in other embodiments, the first defrosting heating stop time and the first defrosting heating stop temperature can be specifically adjusted according to parameters of different types of refrigerators.
S13: and repeatedly switching on and off the fan again after defrosting is stopped.
Further, as shown in fig. 3, repeatedly switching on and off the blower again specifically includes:
s131: and starting the fan at the maximum rotating speed, and judging whether the rotating speed of the fan is smaller than the maximum rotating speed after the fan is started for the second test starting time.
S132: if not, carrying out a normal operation flow, if so, detecting and judging whether the opening times of the fan are smaller than the preset second maximum trial opening times;
s133: if yes, the fan is turned off until the second pause time, the steps are repeated, and if not, the follow-up steps are carried out.
Further, the second maximum number of test openings is less than the first maximum number of test openings.
Here, since the defrosting heating is performed once, reducing the maximum number of trial openings can reduce the amount of heat generated by starting the blower in the case that ice blockage is not resolved, thereby reducing damage to the blower.
The maximum number of pilot openings is, for example, 5. Of course, in other embodiments, the maximum number of times of opening may be adjusted, as long as the second maximum number of times of opening is smaller than the first maximum number of times of opening.
The second test opening time and the second pause time can be adaptively adjusted according to the temperature of the heated defrosting, for example, the second test opening time is shortened and the second pause time is prolonged relative to the parameters in the first fan test opening process; parameters in the first fan test-on procedure may also be used, and detailed descriptions thereof are omitted herein.
S141: after the repeated opening times of the fan in the repeated opening and closing process again reach the second maximum trial opening times, judging whether the fan is still in an abnormal operation state or not;
s142: if yes, starting the defrosting heating device until the temperature reaches the second forced defrosting stop temperature, and if not, performing a normal operation flow.
Further, the second forced defrosting stop condition includes: the starting time of the defrosting heating device reaches a preset second defrosting heating time, or when the defrosting sensor arranged at the defrosting heating device senses that the temperature reaches a preset second defrosting heating stop temperature.
Further, the second forced defrosting heating stop temperature is higher than the first forced defrosting heating stop temperature.
Illustratively, the first defrosting heating stop time is 30 minutes and the first defrosting heating stop temperature is 30 degrees.
Here, since the first defrosting heating has been performed, the second forced defrosting heating stop temperature is raised, which is more advantageous for heating and deicing.
Therefore, in step S11 to step S142, the fan ice blockage solving step by step is realized by the first fan test start flow and the second fan test start flow, and combining with the subsequent forced defrosting flow which is finished under the first forced defrosting stop condition and the second forced defrosting stop condition respectively. The technological parameters are set to be gradually changed, and under the condition that ice blockage is just discovered, the efficiency of solving the ice blockage can be improved under the condition of keeping low energy consumption by carrying out self-starting of the fan for multiple times and defrosting and heating at a lower temperature; after primary defrosting heating, the self-starting times of the fan are reduced, defrosting heating temperature is increased, and the fan can be protected while the efficiency of ending ice blockage is further improved.
Fig. 4 is a schematic flow chart of a second embodiment of a method for controlling ice blockage of a refrigerator fan according to the present application, in the second embodiment, steps S21 to S24 are the same as steps S11 to S14 in the first embodiment, and are not described herein again; the difference is that the step S25 further includes a step S26:
s25: judging whether the fan still operates abnormally, if so, starting the defrosting heating device again and repeatedly switching on and off the fan, and if not, performing a normal flow.
S26: after repeatedly switching on and off the fan each time, if the fan is still in an abnormal operation state, detecting and judging whether the accumulated starting times of the defrosting heating device reach the maximum defrosting times or not;
if yes, outputting a fan fault alarm signal, and if not, repeating the step.
Further, in this embodiment, in each repeated switching process, the number of repeated switching-on times of the fan is limited by the second maximum number of trial switching-on times; and heating to the second forced defrosting stop temperature every time the defrosting heating device is started.
Here, after the switching and defrosting are repeated twice, if there is still a problem in that the fan tries to be turned on, the forced defrosting process and the additional fan try to be turned on process are repeated multiple times to further try to solve the ice blockage problem. Meanwhile, the maximum test running times are set, so that the problem that the fan is further damaged due to repeated ice blockage solving processes still can be avoided under the condition that other sundries are blocked or the fan is damaged and cannot be processed through the control method of the ice blockage of the refrigerator fan. The flow parameters can be simplified on the basis of protecting the fan by using the second maximum start times and the second forced defrosting stop temperature.
Fig. 5 is a schematic flow chart of a third embodiment of a method for controlling ice blockage of a refrigerator fan according to the present application, in which steps S31 to S34 are the same as steps S21 to S24 in the second embodiment, and are not described herein again; the difference is that: the condition parameters in step S35 and step S36 are changed.
Specifically, in step S35 and step S36, the maximum number of times of start-up of the blower and the defrosting heating stop temperature gradually change as the number of repetitions of the step increases. In each repeated switching process, the repeated starting times of the fan gradually decrease along with the increase of the repeated times; each time the defrosting heating device is started, the defrosting stop temperature gradually decreases along with the increase of the repetition times. Through the gradually-changed flow parameters, the control method of the ice blockage of the refrigerator fan is more refined, the ice blockage solving efficiency is further improved, the energy consumption is reduced, and the fan is protected strongly.
As shown in fig. 6, a flow chart of a step of detecting whether the defrosting heating device has a fault in a fourth embodiment of a control method for ice blockage of a refrigerator fan according to the present application is shown, in this fourth embodiment, steps S41 to S45 are the same as steps S11 to S15 in the first embodiment, and are not described herein again; the difference is that, before step S41, step S40 "detect whether there is a failure in the defrosting heating device", which specifically includes:
s401: judging to enter a defrosting step, starting the defrosting heating device, and closing the fan and the compressor to preset conventional defrosting stopping conditions;
s402: judging whether the temperature of the defrosting sensor reaches a preset defrosting end temperature, if so, entering a normal operation flow, and if not, outputting a defrosting device fault alarm and entering a refrigeration flow.
Further, the defrosting end temperature is set in normal operation of the refrigerator.
It can be understood that "entering into a normal operation flow" herein refers to an equal normal operation flow including a control method for solving the ice blockage of the refrigerator fan.
By performing the detecting whether the defrosting heating device has a fault process before entering the flow of the control method of the ice blockage of the refrigerator fan, misjudgment caused by the problem of the defrosting heating device in the fan ice blockage solving process can be avoided.
The application also provides a refrigerator, comprising: the refrigerator fan ice blockage control method is characterized in that the processor executes the program to realize the refrigerator fan ice blockage control method.
The application also provides a computer storage medium in which a computer program is stored and which when run causes a device in which the computer storage medium is located to perform the steps of the method for controlling ice blockage of a refrigerator fan according to any one of claims 1-8.
In summary, the application adopts the step-by-step fan to detect the flow process and the defrosting process, effectively solves the problem of ice blockage caused by freezing of condensed water in the fan of the air-cooled refrigerator by combining mechanical physics and defrosting heating, and can improve the efficiency of solving ice blockage and reduce energy consumption by the step-by-step flow steps.
