Description
CROSS-REFERENCE TO RELATED PRESENT APPLICATIONS
[0001] The present application claims the priority of a Chinese
Patent Application No. PCT/CN2018/124968 entitled "Control Method
and Device for Refrigerator, and Refrigerator" filed on Dec. 28,
2018 by Hefei Midea Refrigerator Co., Ltd., Hefei Hualing Co.,
Ltd., and Midea Group Co., Ltd.
BACKGROUND
Technical Field
[0002] The present disclosure relates to the technical field of
electrical appliances, in particular to a control method and device
for a refrigerator, and the refrigerator.
Description of the Related Art
[0003] 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.
[0004] 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
[0041] 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 examples and are intended to
be illustrative of the present disclosure and are not to be
construed as limiting the present disclosure.
[0042] 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.
[0043] 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.
[0044] 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.
[0045] S101, acquiring a compartment currently requesting
cooling.
[0046] 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.
[0047] 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.
[0048] 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.ltoreq.Tj1 and
Th.ltoreq.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.
[0049] 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 is
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.
[0050] 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.
[0051] 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.
[0052] 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.
[0053] 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 include steps as follows.
[0054] S201, controlling a set compartment to request cooling,
wherein the set compartment is any one of two compartments.
[0055] 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.
[0056] 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.
[0057] 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.
[0058] 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

[0060] 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.
[0061] 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. FIG.
4 is a specific flowchart of a control method for a refrigerator
according to another embodiment of the present disclosure, and as
shown in FIG. 4, the control method for a refrigerator may
specifically include: [0062] S301, acquiring a compartment
currently requesting cooling; [0063] S302, judging whether the
compartment currently requesting cooling is a refrigerating
compartment; [0064] if so, entering step S303; if not, entering
step S306; [0065] S303, acquiring the compartment interior
temperature Tcj and the evaporator outlet temperature Tch of the
refrigerating compartment; [0066] 304, after a first set time,
acquiring the compartment interior temperature Tcj1 and the
evaporator outlet temperature Tch1 of the refrigerating
compartment; [0067] S305, judging whether Tcj>Tcj1 or
Tch>Tch1; [0068] if so, entering step S312; if not, entering
step S310; [0069] S306, acquiring the compartment interior
temperature Tdj and the evaporator outlet temperature Tdh of the
freezing compartment; [0070] S307, acquiring compartment interior
temperature Tdj1 and the evaporator outlet temperature Tdh1 of the
freezing compartment after the first set time; [0071] S308, judging
whether Tdj>Tdj1 or Tdh>Tdh1; [0072] if so, entering step
S312; if not, entering step S309; [0073] S309, interchanging the
currently set valve body rotation angles corresponding to the
refrigerating compartment and the freezing compartment requesting
cooling; [0074] S310, determining any one of the refrigerating
compartment and the freezing compartment as a set compartment, and
controlling the set compartment to request cooling; [0075] S311,
judging whether the set compartment is cooled after a second set
time; [0076] if so, entering step S312; if not, entering step S313;
[0077] S312, keeping the currently set valve body rotation angles
corresponding to the refrigerating compartment and the freezing
compartment requesting cooling unchanged; and [0078] S313, sending
out a refrigerator fault alerting signal.
[0079] According to the control method for a refrigerator provided
by the embodiments of the present disclosure, the refrigerator
includes two compartments. Firstly, a set compartment is controlled
to request cooling and the set compartment is any one of the two
compartments. Then, after a second set time, detecting and
confirming that the set compartment is cooled after the second set
time, the currently set valve body rotation angles corresponding to
the two compartments requesting cooling are kept unchanged; if
detecting and confirming that the set compartment is not cooled
after the second set time, a refrigerator fault alerting signal is
sent out. 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 double-system
refrigerator may be solved, the refrigerator repair rate is
reduced, the refrigerator production efficiency is improved,
fabrication costs are reduced and an alerting signal can be sent
out when the refrigerator fails.
[0080] FIG. 5 is a flowchart of a control method for a refrigerator
according to another embodiment of the present disclosure. When the
refrigerator includes at least three compartments, that is, the
refrigerator is a three-system or a more-system refrigerator, after
step S102 of the embodiment shown in FIG. 2, as shown in FIG. 5,
the control method for a refrigerator may further include steps as
follows.
[0081] S401, interchanging for accumulated 1 time.
[0082] In the embodiment of the present disclosure, after the valve
body rotation angles interchange in the step S103, the
interchanging time is accumulated 1 time, and the initial value of
the interchanging time is 0.
[0083] S402, detecting and confirming that the interchanging time
is smaller than the interchanging time threshold value, controlling
the currently cooled compartment to request cooling, and returning
to the step of acquiring the compartment currently requesting
cooling.
[0084] In the embodiment of the present disclosure, the
interchanging time threshold value can be preset with the
difference between the number of at least three compartments and
the interchanging time threshold value being possible to be 1. If
detecting and confirming that the interchanging time is smaller
than the interchanging time threshold value, the currently cooled
compartment requesting cooling can be controlled by a refrigerator
control system, and step S101 of the embodiment shown in FIG. 2 is
returned to enter a cycle. Until the currently cooled compartment
is cooled, that is, the compartment currently requesting cooling
and the currently cooled compartment are both cooled, the cycle is
withdrawn from, and the currently set valve body rotation angles
corresponding to the at least three compartments requesting cooling
are kept unchanged.
[0085] Further, as shown in FIG. 5, the control method for a
refrigerator may further include steps as follows.
[0086] S403, detecting and confirming that the interchanging time
is equal to the interchanging time threshold value, and controlling
the currently cooled compartment to request cooling.
[0087] In the embodiment of the present disclosure, if detecting
and confirming that the interchanging time is equal to the
interchanging time threshold value, the currently cooled
compartment can be controlled by the refrigerator control system to
request cooling.
[0088] S404, reacquiring a compartment currently requesting
cooling.
[0089] In the embodiment of the present disclosure, the compartment
currently requesting cooling is reacquired.
[0090] S405, detecting and confirming that the compartment
currently requesting cooling is cooled after a third set time, and
keeping the currently set valve body rotation angles corresponding
to at least three compartments requesting cooling unchanged.
[0091] In the embodiment of the present disclosure, the third set
time can be preset, and the third set time can be specifically 5
min. After the third set time, whether the compartment currently
requesting cooling, which is reacquired in step S404, 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 S102 of the embodiment shown in FIG. 2, which will not be
described in detail herein. If detecting and confirming that the
compartment currently requesting cooling after the third set time
is cooled, it can be judged that the two compartments interchanging
the valve body rotation angles are both cooled, and the currently
set valve body rotation angles corresponding to at least three
compartments requesting cooling are kept unchanged.
[0092] S406, detecting and confirming that the compartment
currently requesting cooling is not cooled after the third set
time, and sending out a refrigerator fault alerting signal.
[0093] In the embodiment of the present disclosure, if detecting
and confirming that the compartment currently requesting cooling is
not cooled after the third set time, it is suggested that the
refrigerator may have a fault, and a refrigerator fault alerting
signal is sent out.
