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 is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a control method of a refrigerator, which aims to solve the problem that the existing refrigerator cannot independently control the air volume sent to an ice maker. The following description will be made with reference to the accompanying drawings.
For example, please refer to fig. 1, and fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present application. The embodiment of the application provides a refrigerator 1, and the refrigerator 1 comprises: the refrigerator comprises a shell 10, a compressor 11, an ice maker 12 and an ice making damper 13, wherein the compressor 11 is communicated with or disconnected from the ice maker 12 through the ice making damper 13. The compressor 11, the ice maker 12, and the ice making damper 13 are disposed in the case 10. An ice making air duct 14 is further disposed in the housing 10, one end of the ice making air duct 14 is communicated with the compressor 11, the other end of the ice making air duct 14 is communicated with the ice maker 12, and an ice making damper 13 is disposed between the compressor 11 and the ice maker 12, so that the connection or disconnection between the compressor 11 and the ice maker 12 is controlled by controlling the opening and closing of the ice making damper 13. The housing 10 also has a freezing chamber 15 therein, and when the ice maker 12 makes ice, cold air is generally required to be transferred from the back of the freezing chamber 15 into the ice maker 12, however, such a design is generally incapable of separately controlling the amount of air fed to the ice maker 12, so that the ice making efficiency of the ice maker 12 is reduced.
In view of the above problems, an embodiment of the present invention provides a method for controlling a refrigerator, please refer to fig. 2 in combination with fig. 1, and fig. 2 is a first flowchart of the method for controlling the refrigerator according to the embodiment of the present invention. The control method of the refrigerator comprises the following steps:
101. an operation state of the compressor and an ice making temperature or an ice making time of the ice maker are recognized.
The operation state of the compressor 11 can be divided into three states: a power-on stage state, a sensor control stage state and a defrosting stage state. The power-on state may be understood as the power-on state of the refrigerator 1, and the compressor 11 is also in the power-on state, that is, a state of being changed from the power-off state to the power-on state, and at this time, the ambient temperature outside the refrigerator 1 and the freezing temperature inside the freezing chamber 15 may be the same, that is, both ambient temperatures, and at this time, the opening and closing of the ice making damper 13 may be controlled based on the ambient temperatures. The sensor control stage state may be understood as a stage of an operation state after the refrigerator 1 is powered on, and at this time, the opening and closing of the ice making damper 13 may be controlled according to the temperature and the calculation time collected by a collecting sensor, for example, a freezing sensor, a defrosting sensor, an ice making sensor, and the like. The defrosting stage state refers to a start-up or stop stage of the compressor 11 after the refrigerator 1 is in the defrosting stage. At this time, the opening and closing of the ice making damper 13 may be controlled according to the temperature and the calculation time collected by the collecting sensor. For example, the ice maker 12 may include an ice making sensor 122, the ice making sensor 122 being disposed in a cavity of the ice maker 12, and an ice making temperature of the ice maker 12 being collected by the ice making sensor 122.
102. The opening and closing of the ice making damper is controlled according to the running state of the compressor and the ice making temperature or ice making time of the ice making machine.
The above three operating states of the compressor 11 are known: a power-on stage state, a sensor control stage state and a defrosting stage state. Under different operation states, the opening and closing of the ice making damper 13 can be controlled according to different ice making temperatures of the ice maker 12 or ice making time of the ice maker 12, so that the air volume sent to the ice maker 12 can be controlled, and the function of independently controlling the ice making of the ice maker 12 is realized. The problem that the refrigerator cannot independently control the air volume sent to the ice maker is solved by arranging the ice making damper 13 for independently controlling the air volume sent to the ice maker 12 and the opening and closing control method of the ice making damper 13 according to the running state of the compressor 11 and the ice making temperature of the ice maker 12 or the ice making time of the ice maker 12.
Further, controlling the opening and closing of the ice making damper 13 according to the operation state of the compressor 11 and the ice making temperature of the ice maker 12 or the ice making time of the ice maker 12 includes:
in the first case, when the operation state of the compressor 11 is the power-on stage state, the ice making damper 13 is controlled to be closed. It should be noted that the state at this time may be understood as an initial state of the ice making damper 13, that is, when the compressor 11 is in the power-on stage state, the ice making damper 13 is first reset and closed for subsequent control.
In the second case, when the operation state of the compressor 11 is the sensor control stage state or the defrosting stage state, the ice making damper 13 is controlled to maintain the current state. It can be understood that, the state of the compressor 11 in the sensor control stage or the defrosting stage is the control of the compressor 11 in the operation stage of the refrigerator 1, and at this time, the ice making damper 13 can be controlled to maintain the current state, that is, the state of the ice making damper 13 controlled in the previous step.
For a more clear description of the case of controlling the opening and closing of the ice making damper 13 according to the operation state of the compressor 11 and the ice making temperature of the ice maker 12 or the ice making time of the ice maker 12, please refer to fig. 3 in conjunction with fig. 1, and fig. 3 is a second flow chart of the control method of the refrigerator provided in the embodiment of the present application. The control method of the refrigerator further includes:
201. an operation state of the compressor and an ice making temperature or an ice making time of the ice maker are recognized.
For step 201, reference may be made to the description of step 101, which is not described herein again.
202. The working state of the ice maker, the ambient temperature outside the refrigerator, and the freezing temperature of the freezing chamber of the refrigerator are obtained.
The operating state of the ice maker 12 can be divided into an ice making state, a full ice state, and an ice making stop state, wherein the ice making state includes a quick ice making state and a normal ice making state, and different states correspond to different control logics. The full ice state is a state in which ice cubes made by the ice maker 12 occupy the storage space of the ice maker 12. The ice-making stopped state is a state where ice-making is not required.
203a, when the running state of the compressor is the power-on stage state and the working state of the ice maker is the ice making state, controlling the opening and closing of the ice making damper according to the environment temperature outside the refrigerator, the freezing temperature of the freezing chamber of the refrigerator and the ice making temperature or ice making time of the ice maker.
When the operation state of the compressor 11 is the power-on stage state, that is, the power-on initial operation stage, if the operation state of the ice maker 12 is set to the ice making state, the opening and closing of the ice making damper 13 may be controlled according to the ambient temperature outside the refrigerator 1, the freezing temperature of the freezing chamber 15 of the refrigerator 1, and the ice making temperature of the ice maker 12. The ice making state may include a rapid ice making state and a normal ice making state, for example, whether a rapid ice making button and a normal ice making button of a display control panel of the refrigerator 1 are in an operating state may be detected, and if the rapid ice making button is in a pressed state, it may be understood that a user needs to take out ice cubes made in a short time, and a control scheme capable of rapidly making ice is needed to control the refrigerator 1 and the ice maker 12. Accordingly, when the user does not need to take the made ice cubes within a short time, the refrigerator 1 and the ice maker 12 can be controlled by a control scheme for normally making ice. It should be noted that, the ice making state may also be identified by an automatic detection scheme as the fast ice making state or the normal ice making state, which is only illustrated here by way of example and should not be construed as a limitation on the ice making state.
In the first case, when the operation state of the compressor 11 is the power-on stage state and the operation state of the ice maker 12 is the rapid ice making state, the opening and closing of the ice making damper 13 may be controlled according to the ambient temperature and the ice making temperature or ice making time of the ice maker 12. Illustratively, when the temperature difference between the ambient temperature and the freezing temperature is greater than or equal to the first temperature difference threshold, the ice making damper 13 is controlled to be opened. The selection of the first temperature difference threshold may select one of a plurality of temperature difference thresholds as the first temperature difference threshold according to the ambient temperature. For example, when the ambient temperature is less than 10 ℃, the first temperature difference threshold may be selected to be 25 ℃; when the ambient temperature is greater than or equal to 10 ℃ and less than 20 ℃, the first temperature difference threshold may be selected to be 35 ℃; when the ambient temperature is greater than or equal to 20 ℃ and less than 30 ℃, the first temperature difference threshold may be selected to be 45 ℃; when the ambient temperature is greater than or equal to 30 ℃ and less than 40 ℃, the first temperature difference threshold may be selected to be 55 ℃; when the ambient temperature is greater than 40 ℃, the first temperature difference threshold may be selected to be 65 ℃.
In the second case, when the operation state of the compressor 11 is the power-on stage state and the operation state of the ice maker 12 is the normal ice making state, the opening and closing of the ice making damper 13 may be controlled according to the ambient temperature and the ice making temperature or ice making time of the ice maker 12. Illustratively, when the temperature difference between the ambient temperature and the freezing temperature is greater than or equal to the second temperature difference threshold, the ice making damper 13 is controlled to be opened. The selection of the second temperature difference threshold may select one of a plurality of temperature difference thresholds as the second temperature difference threshold according to the ambient temperature, and the second temperature difference threshold is smaller than the first temperature difference threshold. For example, when the ambient temperature is less than 10 ℃, the second temperature difference threshold may be selected to be 15 ℃; when the ambient temperature is greater than or equal to 10 ℃ and less than 20 ℃, the second temperature difference threshold may be selected to be 25 ℃; when the ambient temperature is greater than or equal to 20 ℃ and less than 30 ℃, the second temperature difference threshold may be selected to be 35 ℃; when the ambient temperature is greater than or equal to 30 ℃ and less than 40 ℃, the second temperature difference threshold may be selected to be 45 ℃; when the ambient temperature is greater than 40 ℃, the second temperature difference threshold may be selected to be 55 ℃.
In the third case, when the operation state of the compressor 11 is the power-on stage state and the operation state of the ice maker 12 is the rapid ice making state or the normal ice making state, the opening and closing of the ice making damper 13 may be controlled according to the ice making temperature or the ice making time of the ice maker 12. Illustratively, the ice making damper 13 is controlled to be closed when the ice making temperature of the ice maker 12 is less than or equal to the first ice making threshold value. The selection of the first ice-making threshold may select one of a plurality of ice-making thresholds as the first ice-making threshold according to an ambient temperature. For example, when the ambient temperature is less than 10 ℃, the first ice-making threshold may be selected to be-18 ℃; when the ambient temperature is greater than or equal to 10 ℃ and less than 20 ℃, the first ice-making threshold may be selected to be-14 ℃; when the ambient temperature is greater than or equal to 20 ℃ and less than 30 ℃, the first ice-making threshold may be selected to be-14 ℃; when the ambient temperature is greater than or equal to 30 ℃ and less than 40 ℃, the first ice-making threshold may be selected to be-14 ℃; when the ambient temperature is greater than 40 ℃, the first ice-making threshold may be selected to be-16 ℃.
Illustratively, the ice making damper 13 is controlled to be closed when the ice making time of the ice maker 12 is greater than or equal to a first time threshold. The selection of the first time threshold may be a selection of one of a plurality of time thresholds as the first time threshold based on the ambient temperature. Also, different first time thresholds may be selected for the rapid ice making state and the normal ice making state.
It should be noted that, when the ice making state of the ice maker 12 is the rapid ice making state, and the temperature difference between the ambient temperature and the freezing temperature is greater than or equal to the first temperature difference threshold, the ice maker 12 may start to fill water, and after the water is filled for a certain time, the ice making damper 13 is controlled to open. The water filling time may be set, for example, to 1 minute after the water filling, and the ice making damper 13 is controlled to be opened. For the selection of the time threshold, reference may be made to the following description. For example, in the rapid ice making state, when the ambient temperature is less than 10 ℃, the first time threshold may be selected to be 220 minutes; when the ambient temperature is greater than or equal to 10 ℃ and less than 20 ℃, the first time threshold may be selected to be 180 minutes; when the ambient temperature is greater than or equal to 20 ℃ and less than 30 ℃, the first time threshold may be selected to be 180 minutes; when the ambient temperature is greater than or equal to 30 ℃ and less than 40 ℃, the first time threshold may be selected to be 180 minutes; when the ambient temperature is greater than 40 ℃, the first time threshold may be selected to be 200 minutes.
When the ice making state of the ice maker 12 is the normal ice making state and the temperature difference between the ambient temperature and the freezing temperature is greater than or equal to the second temperature difference threshold value, the ice maker 12 may start to fill water, and after the water is filled for a certain time, the ice making damper 13 is controlled to be opened. The water filling time may be set to be the same as the time when the ice is rapidly made. For the selection of the time threshold, reference may be made to the following description. For example, in a normal ice making state, when the ambient temperature is less than 10 ℃, the first time threshold may be selected to be 240 minutes; when the ambient temperature is greater than or equal to 10 ℃ and less than 20 ℃, the first time threshold may be selected to be 200 minutes; when the ambient temperature is greater than or equal to 20 ℃ and less than 30 ℃, the first time threshold may be selected to be 180 minutes; when the ambient temperature is greater than or equal to 30 ℃ and less than 40 ℃, the first time threshold may be selected to be 180 minutes; when the ambient temperature is greater than 40 ℃, the first time threshold may be selected to be 220 minutes.
It should be noted that there may be other ways for determining the first ice making threshold, the first time threshold, the first temperature difference threshold, and the second temperature difference threshold, which are only illustrated by way of example and should not be construed as limiting the way for determining the first ice making threshold, the first time threshold, the first temperature difference threshold, and the second temperature difference threshold.
203b, when the running state of the compressor is the sensor control stage state and the working state of the ice maker is the ice making state, controlling the opening and closing of the ice making damper according to the environment temperature and the ice making temperature or ice making time of the ice maker.
When the operation state of the compressor 11 is the sensor control stage state, the opening and closing of the ice making damper 13 may be controlled according to the ambient temperature and the ice making temperature or the ice making time, regardless of whether the operation state of the ice maker 12 is the rapid ice making state or the normal ice making state. Illustratively, when the ice making temperature is greater than or equal to the second ice making threshold, the ice making damper 13 is controlled to be opened. When the ice making temperature is less than the second ice making threshold, the ice making damper 13 is controlled to be closed. The selection of the second ice-making threshold may select one of the plurality of ice-making thresholds as the second ice-making threshold according to an ambient temperature. For example, when the ambient temperature is less than 10 ℃, the second ice-making threshold may be selected to be-14 ℃; when the ambient temperature is greater than or equal to 10 ℃ and less than 20 ℃, the second ice-making threshold may be selected to be-10 ℃; when the ambient temperature is greater than or equal to 20 ℃ and less than 30 ℃, the second ice-making threshold may be selected to be-10 ℃; when the ambient temperature is greater than or equal to 30 ℃ and less than 40 ℃, the second ice-making threshold may be selected to be-10 ℃; when the ambient temperature is greater than 40 ℃, the second ice-making threshold may be selected to be-12 ℃. The selection of the second ice-making threshold may also be determined in other ways, not further exemplified herein.
Illustratively, when the ice making time is greater than or equal to the second time threshold, the ice making damper 13 is controlled to be opened. It should be noted that the ice making time at this time may be understood as water filling time, that is, after the ice making machine 12 is filled with water for the second time threshold, the ice making damper 13 is controlled to open. For example, the second time threshold may be selected to be 1 minute. It will be appreciated that after the ice tray volume for ice making and the water flow rate for water fill are determined, a second time threshold for water fill may be determined.
When the ice making time is greater than or equal to the third time threshold, the ice making damper 13 is controlled to be closed. The third time threshold may be selected from one of a plurality of time thresholds as the third time threshold according to the ambient temperature. For example, when the ambient temperature is less than 10 ℃, the third time threshold may be selected to be 130 minutes; when the ambient temperature is greater than or equal to 10 ℃ and less than 40 ℃, the third time threshold may be selected to be 90 minutes; when the ambient temperature is greater than 40 ℃, the third time threshold may be selected to be 110 minutes.
203c, when the running state of the compressor is a defrosting stage state and the working state of the ice maker is an ice making state, controlling the opening and closing of the ice making damper according to the ice making temperature or ice making time of the ice maker.
The operation state of the compressor 11 is a defrosting stage state, and it should be noted that when the refrigerator 1 is at the end of the defrosting stage, the compressor 11 needs to be turned on for the first time after the end of defrosting, and at this time, the ice making temperature of the ice maker 12 or the ice making time of the ice maker 12 is mainly considered. Illustratively, when the ice making temperature is greater than or equal to the third ice making threshold, the ice making damper 13 is controlled to be opened; when the ice making temperature is less than the third ice making threshold, the ice making damper 13 is controlled to be closed. It should be noted that, when the compressor 11 is stopped, the opening and closing of the ice making damper 13 may be controlled according to the ice making temperature and the defrosting temperature, for example, when the ice making temperature is greater than or equal to the third ice making threshold, the ice making damper 13 is controlled to be opened, and when the defrosting temperature is less than or equal to the third ice making threshold, the ice making damper 13 is controlled to be closed. After the defrosting stage, the compressor 11 is started for 3 minutes, and only the ice making temperature may be considered at this time, for example, when the ice making temperature is greater than or equal to the third ice making threshold, the ice making damper 13 is controlled to be opened; when the ice making temperature is less than the third ice making threshold, the ice making damper 13 is controlled to be closed. The third ice-making threshold does not need to be selected at this time according to the ambient temperature. For example, the third ice-making threshold may be-12 ℃.
Illustratively, when the ice making time of the ice maker 12 is greater than or equal to the fourth time threshold, the ice making damper 13 is controlled to be closed. It should be noted that, when the current state of the ice making damper 13 is in the open state, and the defrosting temperature in the defrosting stage is less than or equal to the third ice making threshold, and the ice making time is greater than or equal to the fourth time threshold, the ice making damper 13 is controlled to be closed. The closing time of the ice making damper 13 may be extended by a time period, for example, 30 minutes, based on the fourth time threshold at the time of the next control period of the ice making damper 13.
And when the ice making time of the ice maker 12 is greater than or equal to the fifth time threshold, controlling the ice making damper 13 to be opened. It should be noted that the current state of the ice making damper 13 is in a closed state, and after defrosting starts, water may be filled into the ice maker 12 for a fifth time threshold, and after the fifth time threshold is filled, the ice making damper 13 is controlled to be opened. The fifth time threshold may be fixed, for example, the fifth time threshold may be 1 minute.

when the ice making temperature is greater than or equal to the fourth ice making threshold, controlling the ice making damper 13 to be opened; and when the ice making temperature is less than or equal to a fifth ice making threshold value, controlling the ice making damper 13 to be closed, wherein the fifth ice making threshold value is less than a fourth ice making threshold value. The selection of the fourth ice making threshold and the fifth ice making threshold may be determined based on the designer's development experience, for example, the fourth ice making threshold may be-1 deg.C and the fifth ice making threshold may be-15 deg.C. The fourth ice making threshold and the fifth ice making threshold are illustrated herein only and should not be construed as limiting the fourth ice making threshold and the fifth ice making threshold.
205b, when the running state of the compressor is the sensor control stage state and the working state of the ice machine is the full ice state, controlling the ice making damper to be closed.
Since the operation state of the compressor 11 is a sensor control stage state, that is, the state of the compressor 11 in the normal state of the refrigerator 1, and the temperature of the ice maker 12 is close to the ice making threshold value at this time, if the operation state of the ice maker 12 is the full ice state, the ice making damper 13 can be directly controlled to be closed, so that energy consumption can be saved.
205c, when the running state of the compressor is a defrosting stage state and the working state of the ice machine is a full ice state, acquiring the defrosting temperature of the defrosting sensor, and controlling the opening and closing of the ice making air door according to the defrosting temperature and the ice making temperature.
When the operation state of the compressor 11 is the defrosting stage state and the operation state of the ice maker 12 is the ice full state, the defrosting temperature of the defrosting sensor 154 is acquired. The defrosting sensor 154 may be provided in the freezing chamber 15 or in the case 10 adjacent to the freezing chamber 15 to collect a temperature at the time of defrosting.
Controlling the opening and closing of the ice making damper 13 according to the defrosting temperature and the ice making temperature includes:

At this time, the determination of the sixth and seventh ice making thresholds need not be based on the ambient temperature regardless of the ambient temperature, and the sixth and seventh ice making thresholds may be determined or selected according to the experience of the developer, for example. For example, the sixth ice-making threshold may be-1 ℃ and the seventh ice-making threshold may be-12 ℃. The sixth and seventh ice making thresholds are merely illustrated herein and should not be construed as limiting the sixth and seventh ice making thresholds.
206. And when the working state of the ice maker is ice making stop, controlling the ice making damper to be closed.
It can be understood that when the operating state of the ice maker 12 is the ice making stop state, that is, when ice making is not required, the ice making damper 13 may be controlled to be closed at this time, so as to save energy consumption.
According to the control method of the refrigerator, the problem that the refrigerator cannot independently control the air volume sent to the ice maker is solved by arranging the ice making air door 13 for independently controlling the air volume sent to the ice maker 12 and the opening and closing control method of the ice making air door 13 according to the running state of the compressor 11 and the ice making temperature or ice making time of the ice maker 12.
