A water supply tank 30 is disposed in the water supply tank mounting portion 23, and a water supply system including a water supply pump 25 is disposed in the pump mounting portion 24.

  Next, the water supply tank 30 and the water supply system will be briefly described. First, the water supply tank 30 is roughly composed of a bottomed tank body 31 having an upper surface opened and a lid body 32 covering the upper surface opening of the tank body 31.

  Next, the ice tray 17 will be described with reference to FIGS. The ice making tray 17 having a rectangular shape in plan view is made of, for example, a synthetic resin, and is partitioned into a plurality of ice making blocks 41 formed inside by a partition wall 40 in a concave shape. The ice making blocks 41 are open at the top, and are formed in, for example, two rows. A water channel 42 that communicates the ice making blocks 41 arranged in the longitudinal direction and a water channel 43 that communicates the two rows of ice making blocks 41 at the front and rear portions. The partition wall 40 is formed so as to widen from the upper end to the lower end of the substantially central portion, that is, from the upper end to the lower end (lowermost portion) of the ice making block 41 and further toward the upper portion.

  Further, the ice tray 17 is rotatably supported by the drive device 18 having a drive motor and the like because the supported portion 44 on the other end side is rotatably fitted (freely fitted) to a support shaft (not shown). Yes.

  Accordingly, water from the water supply tank 30 is injected into one of the left and right ice making blocks 41 near the supported portion 44 of the ice tray 17 through the water supply port at the end of the water injection pipe 36, and each of the water is supplied through the water channels 42 and 43. Water spreads over the ice making block 41, and cool air sent from the cooler 13 to the upper freezer compartment 8 through the slit 15 is blown to the back side of the ice making tray 17 to cool the ice making tray 17 from the bottom side to make ice. Is done.

  Reference numeral 45 denotes an ice detecting lever for detecting whether or not a predetermined amount or more of ice (full ice state) is stored in the ice storage container 21. In addition, an engaging projection 46 is provided at the rear end of the ice tray 17, and when the ice tray 17 is turned upside down by the drive device 18 in the direction of the arrow shown in FIG. The engaging projection 46 is in contact with the upper part of the regulating body 47 provided on the partition wall 6, and the ice that is made by twisting is dropped into the ice storage container 21 and stored.

  Whether or not ice is stored in the ice storage container 21 in a predetermined amount or more, that is, whether or not it is full is determined when the ice detecting lever 45 is moved toward the ice storage container 21 when deicing. Rotate. If the full ice detection sensor 29 as a full ice detection device detects that the ice detecting lever 45 does not receive a force exceeding a predetermined value even if the ice detecting lever 45 rotates at this time. Then, the control device 27 determines that the ice storage container 21 has not stored ice more than a predetermined amount (not full ice), and the deicing operation as described above can be started.

  Next, the control block diagram will be described with reference to FIG. 4. A control device 27 is a microcomputer that controls the refrigerator in an integrated manner. The control device 27 includes a CPU 27A, a RAM 27B that stores various data, and a control program. The ROM 27C and the like are stored, and various operations and functions of the refrigerator are controlled according to programs stored in the ROM 27C based on information such as the temperature detection sensor 26, the ice making completion sensor 28, and the full ice detection sensor 29.

  Hereinafter, operations for ice making and deicing will be described. As described above, the compressor 14B sucks and compresses the refrigerant to obtain high temperature and high pressure, the condenser condenses the high temperature and high pressure gaseous refrigerant from the compressor 14B, and the refrigerant that has become low temperature and low pressure by the capillary tube cools the refrigerant. The cooler 13 is vaporized, and the cool air cooled by the cooler 13 is blown out to the freezer compartment 8 through the slit 15 by the blower 14A. In this case, when the temperature detection sensor 26 detects minus 16 ° C., the control device 27 causes the compressor 14B and the blower 14A to operate, and when minus 18 ° C. is detected, stops the operation of the compressor 14B and the blower 14A. To control.

  Then, water from the water supply tank 30 is injected into one of the left and right ice making blocks 41 near the supported portion 44 of the ice making tray 17 through the water supply port at the end of the water injection pipe 36, and the water is supplied through the water channels 42 and 43. When water reaches the ice making block 41, the cool air sent from the cooler 13 to the upper freezing chamber 8 through the slit 15 is blown to the back side of the ice making tray 17 to cool the ice making tray 17 from the bottom side. Ice making.

  When this ice making is performed and the temperature of the bottom surface of the ice tray 17 becomes minus 11 ° C., the ice making completion sensor 28 detects that ice making is completed, and the detection signal is input to the control device 27.

  Then, the control device 27 to which the detection signal indicating that the ice making is completed controls the ice detecting lever 45 to rotate toward the ice storage container 21. In this case, even if the ice detecting lever 45 rotates by a predetermined angle, when the full ice detection sensor 29 detects that it does not receive a force exceeding a predetermined value when it contacts the ice in the ice storage container 21, The control device 27 determines that the predetermined amount or more of ice is not stored in the ice storage container 21 (is not full of ice), and performs control so that the deicing operation can be started.

  When the temperature detection sensor 26 detects that the room temperature of the freezer compartment 8 is minus 16 ° C., the control device 27 controls the compressor 14B and the blower 14A to operate, and the control device 27 is driven. An operation signal is output to the device 18, and the deicing operation is started. That is, the ice tray 17 is rotated by the drive device 18 while the supported portion 44 is supported by the support shaft, the ice tray 17 is turned upside down, and the engagement protrusion 46 is provided on the partition wall 6. The ice that is in contact with the upper portion of the body 47 and twisted and made into ice falls into the ice storage container 21 and is stored.

  In this case, since the deicing operation is performed when it is detected that the room temperature of the freezer compartment 8 is a high temperature (higher than minus 18 ° C.) minus 16 ° C., the ice is relatively detached from the ice tray 17. Therefore, it is possible to reduce the torque of the driving device 18 when the ice tray 17 is twisted at the time of deicing.

  And after ice falls from the ice tray 17, the ice tray 17 is reversed by the drive device 18, and the ice tray 17 returns to the state before reversal, that is, the state where the opening is turned up. Next, an operation signal is output from the control device 27 to the water supply pump 25.

  For this reason, the water supply pump 25 is operated for a predetermined time, and the water in the water supply tank 30 flows down from the water injection pipe 36 and is supplied to the ice tray 17. In this case, the water supplied to one ice making block 41 at the rear end of the ice tray 17 flows to each adjacent ice making block 41 via each water channel 42, 43. At this time, since each water channel 42, 43 is formed upward from the lower end of each ice making block 41, water supplied to a part of the ice making blocks 41 is supplied to all ice making blocks 41 via each water channel 42, 43. Ice will be supplied almost uniformly to the level of the upper end of the partition wall 40, and ice will be made thereafter.

  The second embodiment will be described mainly based on FIG. A planar heater 48 is provided over the entire bottom surface of the ice tray 17 for heating the ice tray 17. A timer 49 measures the time from the start of energization of the heater 48.

  As described above, when the cool air cooled by the cooler 13 is blown out to the freezer compartment 8 through the slit 15 by the blower 14A and the temperature detection sensor 26 detects minus 16 ° C., the control device 27 causes the compressor 14B and the blower 14A are operated, and when minus 18 ° C. is detected, the compressor 14B and the blower 14A are stopped.

  Then, ice making is performed by cooling the ice tray 17 supplied with water from the water supply tank 30 from the bottom side, and when the temperature of the bottom surface of the ice tray 17 becomes minus 11 ° C., the ice making completion sensor 28 has completed the ice making. , And the detection signal is input to the control device 27. Then, the control device 27 to which the detection signal indicating that the ice making is completed inputs the ice detecting lever 45 toward the ice storage container 21. In this case, even if the ice detecting lever 45 rotates by a predetermined angle, when the full ice detection sensor 29 detects that it does not receive a force exceeding a predetermined value when it contacts the ice in the ice storage container 21, The control device 27 determines that the predetermined amount or more of ice is not stored in the ice storage container 21 (is not full of ice), and performs control so that the deicing operation can be started.

  When the temperature detection sensor 26 detects that the temperature in the freezer compartment 8 is minus 16 ° C., the control device 27 controls the compressor 14B and the blower 14A to operate, and the control device 27 is driven. An operation signal is output to the device 18, and the deicing operation is started. That is, first, the control device 27 controls the heater 48 to start energization. Then, the timer 49 measures the time from the start of energization of the heater 48, and outputs a drive signal to the drive device 18 when it is timed that a predetermined time (for example, 60 seconds) has elapsed since the start of energization.

  For this reason, the ice tray 17 is rotated while the supported portion 44 is supported by the support shaft, the ice tray 17 is turned upside down, and the upper portion of the regulating body 47 provided with the engaging projection 46 on the partition wall 6. The ice that is twisted and made into ice is dropped into the ice storage container 21 and stored. In this case, since the bottom surface of the ice tray 17 is heated by the heater 48, the ice is easily peeled off from the ice tray 17, so that the drive device 18 for twisting the ice tray 17 at the time of deicing is used. Torque can be reduced. Subsequent operations are omitted here.

  In the third embodiment, when the temperature of the freezer compartment 8 rises and reaches a first predetermined temperature (for example, minus 16 ° C.), the compressor 14B and the blower 14A are turned on to perform the cooling operation. An automatic ice maker in a refrigerator that repeatedly operates to stop the cooling operation by turning off the compressor 14B and the blower 14A when the temperature of the freezer compartment 8 decreases and reaches a second predetermined temperature (for example, minus 18 ° C.). The operation of the deicing machine 19 that performs deicing by twisting the ice tray 17 may be performed when the temperature of the freezer compartment 8 is near the first predetermined temperature.

  In this embodiment, the temperature detection device 26 detects the temperature of the freezer compartment 8 and after the completion of ice making, that is, after the completion of ice making is detected by the ice making completion sensor 28, the temperature detection device 26 detects the first predetermined temperature. When the temperature in the vicinity is detected, the deicer 19 may be operated.

  Further, in this embodiment, the cycle of the repeated operation is detected, and the cycle operation is turned on / off so that the temperature of the freezer compartment 8 is close to the first predetermined temperature when the ice making is predicted to be completed by the value of the cycle. The timing may be adjusted.

  Furthermore, in this embodiment, when the temperature setting of the freezer compartment 8 is set to weak cooling by the user, the deicer 19 performs the deicing operation regardless of the temperature of the freezer compartment 8 when the ice making is completed. You may make it start.

  Furthermore, in these embodiments, before the ice removing machine 19 twists the ice tray 17, the heater 48 provided in the ice tray 17 may be energized.

  Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is not limited to the various alternatives described above without departing from the spirit of the present invention.
