BACKGROUND OF THE INVENTION

With the development of economy and technology and the upgrading of consumer demands of a wide range of customers, refrigerators are developing towards large volume and multi-function. As the basic technology of refrigerators, refrigerating systems have also developed from single systems to multiple systems. Multi-system refrigerators are featured with multiple capillary tubes and one solenoid valve with "one-in-multiple-out". After multiple outlet tubes of the solenoid valve are mutually connected with multiple capillary tubes, the corresponding relationship between the rotation angle of the valve body of the solenoid valve and the capillary tubes connected with the solenoid valve is preset by a program. When cooling is requested, the valve body of the solenoid valve operates according to a preset control rule, and the purpose of cooling each compartment can be achieved.
In the related art, when a refrigerator is designed, multiple outlet tubes of the solenoid valve and multiple capillary tubes corresponding to the outlet tubes are identically marked according to a set rule such that only the outlet tubes of the solenoid valve with identical marks are needed to be connected with the capillary tubes and welded well during the production. However, because the label falls off during the transportation or the operation of workers is not careful and like circumstances, error connections between the outlet tube of the solenoid valve and the capillary tube may still occur such that the refrigerator cannot be cooled normally, and the refrigerator can only be found abnormally operating and repaired after being subjected to commercial inspections, causing the production efficiency of the refrigerator to be low and fabrication costs to be high.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Like or similar reference numerals refer to the same or similar elements or have elements with the same or similar function throughout the text. The embodiments described below by reference to the drawings are exemplary and are intended to be illustrative of the present disclosure and are not to be construed as limiting the present disclosure.
The control method and device of a refrigerator, and the refrigerator in the embodiments of the present disclosure are described below with reference to the drawings.
Firstly, the working principle of a solenoid valve of a multi-system refrigerator is introduced by taking a three-system refrigerator including refrigerating, freezing, and temperature changing compartment as an example. Fig. 1 is a working principle diagram of a solenoid valve of a three-system refrigerator. As shown in Fig. 1, the solenoid valve of the three-system refrigerator is a "one-in-three-out" solenoid valve which includes three outlet tubes A, B, and C, and has three connection modes. Three outlet tubes A, B, and C of the solenoid valve respectively correspond to three specific rotation angles of the solenoid valve; after the valve body of the solenoid valve rotates by a rotation angle corresponding to the A outlet tube, the A outlet tube is connected; after the solenoid valve body rotates by a rotation angle corresponding to the B outlet tube, the B outlet tube is connected; after the solenoid valve body rotates by a rotation angle corresponding to the C outlet tube, the C outlet tube is connected. The capillary tubes corresponding to refrigerating, freezing and temperature changing are respectively connected with the three outlet tubes of the solenoid valve, then the connection mode and the rotation angles of the corresponding solenoid valves are written into a program. When the refrigerating, freezing, and temperature changing compartments request cooling, the program drives the valve body of the solenoid valve to rotate a corresponding rotation angle such that the capillary tubes corresponding to the compartment requesting cooling can be connected and cooling is realized.
Fig. 2 is a flowchart of a control method for a refrigerator according to one embodiment of the present disclosure, and as shown in Fig. 2, the control method for a refrigerator includes the following steps.
S101, acquiring a compartment currently requesting cooling.
According to the embodiment of the present disclosure, the refrigerator includes at least two compartments, in which a compartment currently requesting cooling is acquired. Specifically, every time after a compressor is started or every time after defrosting is finished, the compartment currently requesting cooling is acquired such that the out-of-step of the solenoid valve caused by the loss of a control signal in the control process is avoided, and the abnormal cooling of the refrigerator is prevented.
S102, detecting and confirming that the compartment currently requesting cooling is not cooled after a first set time, determining a currently cooled compartment, and interchanging currently set valve body rotation angles corresponding to the compartment currently requesting cooling and the currently cooled compartment requesting cooling.
In the embodiment of the present disclosure, the first set time can be preset, the first set time can be specifically 5 minutes (min), and after the first set time passes, whether the compartment currently requesting cooling is cooled or not is detected. Specifically, compartment temperature sensors can be respectively arranged in at least two compartments of the refrigerator, defrosting temperature sensors are respectively arranged at evaporator outlets of the at least two compartments of the refrigerator, the compartment temperature sensors and the defrosting temperature sensors can be connected with a refrigerator control system, and the refrigerator control system can acquire the compartment interior temperature collected by the compartment temperature sensors and the evaporator outlet temperature collected by the defrosting temperature sensors in real time. In step S101, after acquiring the compartment currently requesting cooling, an initial compartment interior temperature Tj and an initial evaporator outlet temperature Th of the compartment currently requesting cooling are collected through a refrigerator control system. After the first set time, compartment interior temperature Tj1 and evaporator outlet temperature Th1 currently requesting cooling after the first set time are collected through the refrigerator control system, and Tj is compared with Tj1, and Th is compared with Th1 to determine whether the compartment currently requesting cooling is cooled or not. If Tj≤Tj1 and Th≤Th1, that is, the compartment interior temperature is equal to or greater than the initial compartment interior temperature after the first set time and the evaporator outlet temperature is equal to or greater than the initial evaporator outlet temperature after the first set time, it can be judged that the compartment currently requesting cooling is not cooled; if Tj>Tj1 or Th>Th1, that is, the compartment interior temperature is less than the initial compartment interior temperature after the first set time and the evaporator outlet temperature is less than the initial evaporator outlet temperature after the first set time, it can be judged that the compartment currently requesting cooling is cooled.
It is detected and confirmed that the compartment currently requesting cooling is not cooled after the first set time, suggesting that the connection between the capillary tube and the outlet tube of the solenoid valve at the moment may be wrong; a currently cooled compartment is determined; and currently set valve body rotation angles corresponding to the compartment currently requesting cooling and the currently cooled compartment requesting cooling are interchanged, so that the compartment currently requesting cooling is cooled. Specifically, if the refrigerator includes two compartments, namely the refrigerator is a double-system refrigerator, the compartment which does not request cooling in the two compartments is currently cooled compartment; if the refrigerator includes at least three compartments, that is, the refrigerator is a three-system or more-system refrigerator, it may be necessary to judge successively whether a compartment which does not request cooling among the at least three compartments is cooled in order to determine the currently cooled compartment. The mode of detecting whether the compartment is cooled can specifically refer to the above description, which will not be described in detail herein.
Further, the control method for a refrigerator further includes: detecting and confirming that the compartment currently requesting cooling is cooled after the first set time, and keeping the currently set valve body rotation angles corresponding to the at least two compartments requesting cooling unchanged.
According to the embodiment of the present disclosure, if it is detected and confirmed that the compartment currently requesting cooling is cooled after the first set time, it indicates that the capillary tube is correctly connected with the outlet tube of the solenoid valve at the moment, no adjustment is needed and the valve body rotation angles corresponding to the currently set at least two compartments requesting cooling are kept unchanged.
According to the control method for a refrigerator provided by the embodiment of the present disclosure, the refrigerator includes at least two compartments. The control method for a refrigerator includes: firstly, acquiring a compartment currently requesting cooling; then detecting and confirming that the compartment currently requesting cooling is not cooled after a first set time, determining a currently cooled compartment, and interchanging currently set valve body rotation angles corresponding to the compartment currently requesting cooling and the currently cooled compartment requesting cooling. By determining a currently cooled compartment, and interchanging currently set valve body rotation angles corresponding to the compartment currently requesting cooling and the currently cooled compartment requesting cooling, the compartment currently requesting cooling is cooled such that the problem in which a refrigerator cannot be cooled normally due to a connection error between the capillary tube and a solenoid valve during the production of a multi-system refrigerator may be solved, the refrigerator repair rate is reduced, the refrigerator production efficiency is improved, and fabrication costs are reduced.
Fig. 3 is a flowchart of a control method for a refrigerator according to another embodiment of the present disclosure. When the refrigerator includes two compartments, that is, the refrigerator is a double-system refrigerator, after step S102 of the embodiment shown in Fig. 2, as shown in Fig. 3, the control method for a refrigerator may further includes steps as follows.

In the embodiment of the present disclosure, the set compartment can be controlled by the refrigerator control system to request cooling, wherein the set compartment is any one of two compartments, that is, the set compartment can be a compartment currently requesting cooling or a compartment not currently requesting cooling.
S202, detecting and confirming that set compartment is cooled after a second set time, and keeping the currently set valve body rotation angles corresponding to the two compartments requesting cooling unchanged.
In the embodiment of the present disclosure, the second set time can be preset, and the second set time can be specifically 5 min. After the second set time, whether the set compartment is cooled or not is detected, and the mode of detecting whether the compartment is cooled or not can specifically refer to the detailed description of step S102 of the embodiment shown in Fig. 2, which will not be described in detail herein.
If detecting and confirming the set compartment to be cooled after the second set time, it is judged that both the compartment currently requesting cooling and the currently cooled compartment are cooled, and the currently set (that is, after the rotation angles are interchanged) valve body rotation angles corresponding to the two compartments requesting cooling are kept unchanged.
S203, detecting and confirming that the set compartment is not cooled after the second set time, and sending out a refrigerator fault alerting signal.
In the embodiment of the present disclosure, if detecting and confirming that the set compartment is not cooled after the second set time, it can be judged that at least one of the compartment currently requesting cooling and the currently cooled compartment is not cooled, the refrigerator is abnormally cooled, and a refrigerator failure alerting signal is sent out.
In order to clearly illustrate the above-mentioned embodiments, embodiments of the present disclosure will be described in detail by taking a dual-system refrigerator including two compartments of freezing and refrigerating as an example.
