Definitions

  • the present invention relates to a refrigerator with a refrigerating compartment and a freezing compartment and a control method for the same.
  • refrigerators include a body containing freezing and refrigerating compartments divided by a wall. Separate doors are generally provided for the freezing and refrigerating compartments. An evaporator and a fan are located behind a wall at the back of the freezing compartment, in order to generate cold air which is supplied to the freezing compartment. Another evaporator and another fan are arranged behind a wall at the back of the refrigerating compartment, in order to generate cold air which is supplied to the refrigerating compartment. Thus, cold air is supplied to the freezing and refrigerating compartments independently. Such a system is called an "independent cooling system".
  • the independent cooling system is used because the freezing compartment needs to be cooled significantly more than the refrigerating compartment.
  • the evaporators of the freezing and refrigerating compartments must have different evaporation temperatures.
  • expansion (pressure reduction) of a refrigerant at the upstream sides of each evaporator must be carried out in such a manner that the expansion degrees are different. Accordingly, a first expansion device is provided for the refrigerating compartment evaporator and a second expansion device is provided for the freezing compartment evaporator.
  • EP 1 394 481 discloses a refrigerator with a path change device that diverts the refrigerant between the expansion devices for the freezing and refrigerating compartments, that is adapted to vary a refrigerant flow path in order to increase the speed and efficiency of cooling for a selected one of the freezing and refrigerant compartments.
  • JP 2002 213626 discloses a valve for controlling refrigerant flow, for which first refrigerant path or a second refrigerant path can be continuously supplied with refrigerant.
  • the different evaporation temperatures of the evaporators for the freezing and refrigerating compartments means different refrigerant pressures in the evaporators.
  • Such a refrigerant pressure difference causes the refrigerant to flow through one of the evaporators in a larger quantity so that the refrigerant may not flow smoothly through the other evaporator when the refrigerant flow path is changed.
  • the invention also includes a method of controlling a refrigerator as claimed in claim 4.
  • refrigerant which is discharged from a compressor 201, is fed to a refrigerating compartment capillary tube 304 or a freezing compartment capillary tube 308 after passing through a condenser 302 according to the state of 3-way valve 310.
  • the 3-way valve 310 is operated such that a refrigerating compartment valve 310a thereof is closed and a freezing compartment valve 310b thereof is open, the refrigerant emerging from the condenser 302 is only fed to the freezing compartment evaporator 207 through the freezing compartment capillary tube 308. In this case, cooling is carried out in the freezing compartment 220 alone.
  • the 3-way valve 310 is operated to open the refrigerating compartment valve 310a and close the freezing compartment valve 310b.
  • the refrigerant emerging from the condenser 302 is fed into the refrigerating compartment evaporator 205 and then into the freezing compartment evaporator 207 via the refrigerating compartment capillary tube 304 and a connecting capillary tube 306.
  • the state of the 3-way valve 310 is controlled by a stepping motor (not shown). That is, a refrigerant flow path, which communicates with at least one of the refrigerating compartment evaporator 205 and freezing compartment evaporator 207, is set by operation of the stepping motor.
  • different or no refrigerant flow paths are established by selectively opening one or other or both or none of the refrigerating compartment valve 310a and the freezing compartment valve 310b using the stepping motor.
  • the angular position of the stepping motor is 34°
  • both the refrigerating compartment valve 310a and the freezing compartment valve 310b are closed so that no refrigerant flow path is established.
  • the stepping motor further rotates to about 95°
  • the freezing compartment valve 310b is opened while the refrigerating compartment valve 310b is still closed. In this state, a refrigerant flow path is established through the freezing compartment evaporator 207 via the freezing compartment capillary tube 308.
  • a further rotation of the stepping motor to about 154° opens the refrigerating compartment valve 310b as well.
  • the stepping motor further rotates to about 195°, the freezing compartment valve 310b is closed while the refrigerating compartment valve 310a remains open. In this state, a refrigerant flow path is established only through the refrigerating compartment evaporator 205 via the refrigerating compartment capillary tube 304.
  • a further rotation of the stepping motor to 215° closes the refrigerating compartment valve 310a as well. As a result, there is no refrigerant flow paths.
  • the establishment of a desired refrigerant flow path is effected by rotation of the stepping motor so as to control the openings and closings of the 3-way valve.
  • a certain angular position of the stepping motor for example, about 154° in the case of Figure 2, there is a simultaneous opening stage t0 in which both the refrigerating compartment valve 310a and the freezing compartment valve 310b are open.
  • the refrigerant can flow through the refrigerating compartment evaporator 205 and the freezing compartment evaporator 207.
  • the refrigerant flows toward the freezing compartment evaporator 207 in a larger quantity because the pressure of the freezing compartment evaporator 207 is relatively higher than that of the refrigerating compartment evaporator 205.
  • the operation mode of the refrigerator is changed from a mode for cooling the refrigerating compartment to a mode for cooling the freezing compartment alone (that is, the angular position of the stepping motor is changed from 195° to 95° via an angular position of about 154°)
  • the refrigerant concentrated to the freezing compartment evaporator 207 cannot be sufficiently supplied through the refrigerant flow path communicating with the refrigerating compartment evaporator 205.
  • the simultaneous opening stage t0 corresponding to the position of about 154°, is maintained for a relatively long period of time.
  • both the refrigerating compartment valve 310a and the freezing compartment valve 310b are open for a sufficient period of time to allow the refrigerant concentrated to the freezing compartment evaporator 207 to be sufficiently and smoothly supplied through the refrigerant flow path communicating with the refrigerating compartment evaporator 205.
  • the refrigerator includes the control system shown in Figure 3.
  • an input unit 354 and a temperature detecting unit 356 are connected to an input of a control unit 352 for controlling the operation of the refrigerator.
  • the input unit 354 allows the user to set a desired target cooling temperature, a desired cooling mode and other operating conditions.
  • the temperature detecting unit 356 detects the temperatures of the refrigerating compartment 210, the freezing compartment 220, the refrigerating compartment evaporator 205 and the freezing compartment evaporator 207 and other temperatures and informs the control unit 352 of the detected temperatures. Based on the detected temperatures, the control unit 352 controls the cooling operation of the refrigerator.
  • the 3-way valve 310 is electrically connected to an output of the control unit 352, along with a compressor 201.
  • the 3-way valve 310 and compressor 201 are controlled by the control unit 352 to implement a cooling mode and achieve a target cooling temperature set by the user.
  • the operation of the control unit 352 will now be described with reference to Figures 4 and 5.
  • Step 402 After completion of the cooling of the refrigerating compartment 210, the control unit 352 determines whether or not the freezing compartment 220 needs cooling. Based on this determination, the control unit 352 determines whether or not the refrigerant flow path needs to be changed from the refrigerating compartment 210 to the freezing compartment 220 (Step 404).
  • Step 406 the control unit 352 changes the angular position of the stepping motor from 195° to 154°.
  • This procedure is an intermediate procedure involved in a procedure in which the stepping motor is rotated to 95°.
  • both the refrigerating compartment valve 310a and the freezing compartment valve 310b are open.
  • the stepping motor is rotated to the 95° position without any delay in the intermediate procedure, thereby closing the refrigerating compartment valve 310a while opening only the freezing compartment valve 310b to cool only the freezing compartment 220 (Step 408).
  • the time, for which both of the valves 310a, 310b are open is minimized during the change of the refrigerant flow path from the refrigerating compartment 210 to the freezing compartment 220. Accordingly, it is possible to reduce the degree of concentration of the refrigerant from the refrigerating compartment evaporator 205 to the freezing compartment evaporator 207.
  • Step 502 After completion of the cooling of the freezing compartment 220, it is determined whether or not the refrigerating compartment 210 needs to be cooled. Based on this determination, it is then determined whether or not the refrigerant flow path needs to be changed from the freezing compartment 220 to the refrigerating compartment 210 (Step 504).
  • Step 506 When it is necessary to change the refrigerant flow path from the freezing compartment 220 to the refrigerating compartment 210, the angular position of the stepping motor is changed from 95° to 154° (Step 506).
  • This procedure is an intermediate procedure involved in a procedure in which the stepping motor is rotated to 195°.
  • a simultaneous opening stage in which both the refrigerating compartment valve 310a and the freezing compartment valve 310b are both open, is established. Where the refrigerant flow path is to be changed from the freezing compartment 220 to the refrigerating compartment 210, the simultaneous opening stage established in the intermediate procedure is continued for a predetermined time (for example, 10 seconds).
  • both the refrigerating compartment valve 310a and the freezing compartment valve 310b are open for the predetermined time (Step 508).
  • both of the valves 310a and 310b are open for the predetermined time during the change of the refrigerant flow path from the freezing compartment 220 to the refrigerating compartment 210, as described above, the refrigerant concentrated to the freezing compartment evaporator 220 can sufficiently flow toward the refrigerating compartment evaporator 210.
  • the predetermined time for which both the refrigerating compartment valve 310a and the freezing compartment valve 310b are open, upon changing the refrigerant flow path from the freezing compartment 220 to the refrigerating compartment 210, is set to be longer than the inevitable delay time (for example, 10 seconds), in order to allow the refrigerant concentrated to the freezing compartment evaporator 220 to flow sufficiently toward the refrigerating compartment evaporator 210.
  • the stepping motor is rotated to 195°, thereby closing the freezing compartment valve 310b while maintaining only the refrigerating compartment valve 310a in the open state.
  • Step 510 only the refrigerating compartment 210 is cooled
