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, fig. 1 is a schematic structural diagram of a refrigerator provided in 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. the working state of the ice maker and the ambient temperature outside the refrigerator are acquired.
102. The opening and closing of the ice making air door are controlled according to the working state of the ice making machine and the ambient temperature.
With respect to 101 and 102:
for example, the open/close control of the ice making damper 13 may be controlled according to the operating state of the ice maker 12 and the ambient temperature outside the refrigerator 1. The operating state of the ice maker 12 determines whether ice making is required and whether rapid ice making is required, and the ambient temperature determines the timing of opening or closing the ice making damper 13. 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. Different control logics can be implemented for the ice making damper 13 according to different operating states of the ice maker 12 and the ambient temperature.
The opening and closing of the ice making damper 13 can be controlled according to different environmental temperatures under different working states of the ice maker 12, so that the air quantity sent to the ice maker 12 can be controlled, and the function of independently controlling the ice maker 12 to make ice is realized. The problem that the refrigerator cannot independently control the air volume supplied to the ice maker is solved by arranging the ice making air door 13 for independently controlling the air volume supplied to the ice maker 12 and the method for controlling the opening and closing of the ice making air door 13 according to the working state and the environmental temperature of the ice maker 12.
For a clearer explanation of the situation of controlling the opening and closing of the ice making damper 13 according to the operating state of the ice maker 12 and the ambient temperature, 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 comprises the following steps:
201. the working state of the ice maker and the ambient temperature outside the refrigerator are acquired.
Reference may be made to the description of steps 101 and 102, which are not repeated herein.
202. When the working state of the ice maker is an ice making state, the freezing temperature of the freezing chamber of the refrigerator and the ice making temperature of the ice maker are obtained, and the opening and closing of the ice making damper are controlled according to the ice making state, the ambient temperature, the freezing temperature and the ice making temperature of the ice maker.
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.
When the operating 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. For example, 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 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 ℃.
When the operating 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. 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 open. 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 ℃.
When the operating 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. For example, when the ice making temperature of the ice maker 12 is less than or equal to the first ice making threshold, the ice making damper 13 is controlled to be closed. 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 ℃; the first ice-making threshold may be selected to be-14 ℃ when the ambient temperature is greater than or equal to 10 ℃ and less than 20 ℃; 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 ℃.
It should be noted that there may be other ways for determining the first ice making threshold value, the first temperature difference threshold value and the second temperature difference threshold value, which are only illustrated here by way of example and should not be construed as limiting the way of determining the first ice making threshold value, the first temperature difference threshold value and the second temperature difference threshold value.
In addition, when the ice making state of the ice maker 12 is the rapid ice making state or the normal ice making state, and the ice making temperature of the ice maker 12 is less than or equal to the first ice making threshold value, the ice making damper 13 is kept open for a first period of time, and then the ice making damper 13 is controlled to be closed. It can be understood that when it is determined that the ice making temperature of the ice maker 12 is less than or equal to the first ice making threshold, that is, the ice making is required, a first time period may be waited to keep the ice making state, so that the amount of power for subsequently making ice can be saved. The first time period may be determined according to the ambient temperature, for example, when the ambient temperature is less than 10 ℃, the first time period may be selected to be 35 minutes; when the ambient temperature is greater than or equal to 10 ℃ and less than 40 ℃, the first time period may be selected to be 25 minutes; the first time period may be selected to be 30 minutes when the ambient temperature is greater than 40 ℃. Of course, the selection of the first time period may also be made according to other ways, which are merely illustrated herein and should not be construed as limiting the first time period.
203. And when the working state of the ice maker is a full ice state, controlling the opening and closing of the ice making air door according to the ice making temperature.
When the ice maker 12 is in the full ice state, controlling the opening and closing of the ice making damper 13 according to the ice making temperature includes:
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.
204. And when the working state of the ice maker is the ice making stop state, 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.
For example, please refer to fig. 4 in combination with fig. 1, and fig. 4 is a third flowchart of a control method of a refrigerator according to an embodiment of the present application. The control method of the refrigerator comprises the following steps:
301. the working state of the ice maker and the ambient temperature outside the refrigerator are acquired.
The description of steps 101 and 102 can be referred to above, and will not be repeated herein.
302. When the working state of the ice maker is the ice making state, the freezing temperature of the freezing chamber of the refrigerator and the ice making time of the ice maker are obtained, and the opening and closing of the ice making damper are controlled according to the ice making state, the ambient temperature, the freezing temperature and the ice making time of the ice maker.
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.
When the operating 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 time. For example, 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 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 ℃.
When the operating 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. 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 open. 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 ℃.
When the operating 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 time. For example, when the ice making time of the ice maker 12 is greater than or equal to the first time threshold, the ice making damper 13 is controlled to be closed. 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 rapid ice making is performed. 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 as 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.
In addition, when the ice making state of the ice maker 12 is the rapid ice making state or the normal ice making state, and the ice making time of the ice maker 12 is greater than or equal to the first time threshold, the ice making damper 13 is kept open for the first time period, and then the ice making damper 13 is controlled to be closed. It can be understood that when it is determined that the ice making time of the ice maker 12 is greater than or equal to the first time threshold, that is, the ice making is required, the first time period may be waited to maintain the ice making state, so that the amount of electricity for subsequently making ice can be saved. The first time period may be determined based on the ambient temperature, for example, when the ambient temperature is less than 10 ℃, the first time period may be selected to be 35 minutes; when the ambient temperature is greater than or equal to 10 ℃ and less than 40 ℃, the first time period may be selected to be 25 minutes; the first time period may be selected to be 30 minutes when the ambient temperature is greater than 40 ℃. Of course, the selection of the first time period may also be made in other ways, which are merely illustrated herein and should not be construed as limiting the first time period.
303. And when the working state of the ice maker is the full ice state, acquiring the ice making temperature of the ice maker, and controlling the opening and closing of the ice making air door according to the ice making temperature.
When the ice maker 12 is in the full ice state, controlling the opening and closing of the ice making damper 13 according to the ice making temperature includes:
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 ℃ and the fifth ice making threshold may be-15 ℃. 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.
304. And when the working state of the ice maker is the ice making stop state, 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.
