Description

  The present invention relates to a refrigerator-freezer equipped with an automatic ice making device.

  In recent years, refrigerator-freezers equipped with an automatic ice making device have become mainstream (see, for example, Patent Document 1).

  FIG. 15 shows a refrigerator-freezer equipped with a conventional automatic ice making device described in Patent Document 1. FIG. 16 is a flowchart showing the operation of a conventional refrigerator-freezer. FIG. 17 is a flowchart showing the operation of a conventional automatic ice making device.

  As shown in FIG. 15, the refrigerator-freezer body 1 includes an outer box 2, an inner box 3, and a heat insulating material 4 filled between the outer box 2 and the inner box 3. The inside of the refrigerator-freezer main body 1 is partitioned vertically by a partition wall 5, and a refrigerator compartment 6 is formed at the top, a switching chamber 7 and an ice making chamber 8 at the center, and a freezer compartment 9 at the bottom.

  The cooler 10 is provided on the back surface of the freezer compartment 9 to generate cold air and forcibly circulate the cold air generated by the blower 11 to form a part of the refrigeration cycle. The internal temperature detection means 12 is means for detecting the internal temperature from the internal temperature detection thermistor 13 installed in the freezer compartment 9, and the internal temperature determination means 14 is detected by the internal temperature detection means 12. It is means for determining whether the measured temperature is equal to or higher than the set temperature. The compressor driving means 15 is means for operating the compressor 16 of the refrigeration cycle. When the ice tray 17 is attached to a household refrigerator-freezer, the ice tray 17 is located in the vicinity of the cold air outlet of the ice making chamber 8 so that the cold air generated by the cooler 10 and the blower 11 is directly applied. .

  The ice making temperature determining means 18 estimates the ice making temperature based on the correlation between the integrated operation time of the blower 11 and the detected temperature of the internal temperature detecting means 12, and determines the ice making completion temperature based on the estimated ice making temperature. decide. The water supply tank 19 is installed in the refrigerator compartment 6 when it is attached to a domestic refrigerator-freezer. The water supply pump motor 20 supplies water from the water supply tank 19 to the ice tray 17. The ice removing mechanism 21 has a function of rotating the ice tray 17 with a motor and twisting the ice making plate 17 to remove the ice. The ice removing mechanism 21 is configured in an ice making case 22 surrounded by plastic or the like.

  An ice storage box 23 for storing the dropped ice is disposed under the ice tray 17. The ice making case 22 includes an ice detecting lever 24 that moves up and down in conjunction with the motor of the ice removing mechanism 21 with a part of the ice making case 22 that detects the amount of ice in the ice storage box 23 as a fulcrum. It is located on the ice storage box 23. When the motor of the deicing mechanism 21 starts to move, the ice detecting lever 24 starts to descend and reaches the lowest position after a certain time. Further, when the motor of the ice removing mechanism 21 is moved, the ice detecting lever 24 starts to rise and finally the ice detecting lever 24 returns to the initial position. If the ice detecting lever 24 hits an obstacle such as ice while the ice detecting lever 24 goes down, the ice detecting lever 24 stops on the spot, but the motor of the ice removing mechanism 21 continues to move.

  The ice detecting lever 24 is also raised in conjunction with the operation of raising the ice detecting lever 24 after a certain period of time since the motor of the ice removing mechanism 21 starts to move. The ice making case 22 includes an ice making amount detection switch 25 including a micro switch that detects the amount of ice by a series of operation amounts of the series of ice detecting levers 24. Further, the ice making temperature determining means 26 determines whether the temperature determined by the ice making temperature determining means 18 is equal to or lower than a set temperature. The deicing determining means 27 is a means for determining whether or not a series of operations in which the ice removing mechanism 21 twists the ice making plate 17 to remove the ice to return to the original horizontal position by the rotation of the motor of the ice removing mechanism 21 is completed. It is. The ice making amount detection means 28 is a means for detecting the state of the ice making amount detection switch 25, and the ice making amount determination means 29 is a means for determining from the ice making amount detection means 28 whether the ice storage box 23 is full. . The motor driving means 30 is means for operating the motor of the deicing mechanism 21 from the ice making temperature determination means 26. The feed water pump motor drive means 31 is means for operating the feed water pump motor 20.

  The water supply timer 32 is a timer that counts the time during which the water supply pump motor 20 is operating, and determines whether the time is up. The first timer 33 is a timer that counts from when the ice making amount determination means 29 is full and the motor driving means 30 stops the motor of the deicing mechanism 21 and also determines whether the time is up. The second timer 34 is a timer that counts from the time when the motor of the ice removing mechanism 21 starts to move, and determines whether the time is up. The third timer 35 also determines whether the time is up or not by a timer that counts when the ice making amount determining means 29 is in a state where the ice storage amount is insufficient and the water supply pump motor 20 supplies water from the water supply tank 19 to the ice tray 17.

  The operation of the refrigerator-freezer configured as described above will be described below with reference to FIG.

  First, in step 1, the internal temperature detection means 12 detects the internal temperature of the freezer from the internal temperature detection thermistor 13 installed in the freezer compartment 9. Next, in step 2, the internal temperature determination means 14 determines whether the temperature detected by the internal temperature detection means 12 is higher or lower than the set temperature. If higher, the compressor driving means 15 in step 3 causes the compressor 16 to Return to step 1. However, if it is determined in step 2 that the internal temperature is low, the process proceeds to step 4 where the compressor driving means 15 stops the compressor 16 and the process returns to step 1. This cycle is repeated to cool the inside of the cabinet.

  Next, the operation of the automatic ice making device will be described with reference to FIG.

  First, in step 101, the ice making temperature determining means 18 estimates the ice tray temperature from the accumulated operation time of the blower 11 and the detected temperature of the internal temperature detecting means 12 by the correlation, and the estimated ice making temperature is obtained. The ice making completion temperature is determined based on this. Next, in step 102, the ice making temperature determination means 26 determines whether the temperature determined in step 101 is higher or lower than the set temperature. If it is higher, the process returns to step 101, and if it is lower, it is determined that ice making has been completed. Then, the motor driving means 30 operates the motor of the ice removing mechanism 21 and starts the second timer 34 in the next step 104. In step 105, it is determined whether or not the second timer 34 has been counted for a certain time, and the process waits until the time is up.

  The motor of the deicing mechanism 21 is moving during this time, and the operation is such that the ice detecting lever 24 first falls and hits the ice in the ice storage box 23 to reach the lowest point without stopping or hitting it, and then moves up. Yes. The ice making amount detection switch 24 judges the amount of ice based on the operation amount of the ice detecting lever 24, and is turned off when there is a lot of ice and turned on when there is little ice. When the series of operations of the ice detecting lever 24 is finished, the time count of the second timer 34 is also finished and the routine proceeds to step 106. In step 106, the ice making amount detection means 28 detects the state of the ice making amount detection switch 25. In the next step 107, if the ice making amount determination means 29 determines that the ice making amount is small, the process proceeds to step 108 and performs the ice removing operation. .

  In step 108, the deicing determining means 27 is a series of the ice removing mechanism 21 that rotates the ice making tray 17 by the motor of the ice removing mechanism 21 and twists the ice to remove the ice from the ice making plate 17 and return it to the original horizontal position. It is determined whether or not the above operation has been completed. If it is determined that the operation has been completed, the routine proceeds to step 109, where the motor driving means 30 stops the motor of the deicing mechanism 21. In step 110, the water supply pump motor driving means 31 operates the water supply pump motor 18 to supply water to the empty ice tray 17 and starts the water supply timer 31 in step 111. In step 112, it is determined whether or not the water supply timer 31 has counted for a certain time, and the water supply pump motor 20 is operated until the time is up. When the water supply timer 32 expires in step 112, the water supply pump motor drive means 31 stops the water supply pump motor 20 in the next step 113.

Since the water supply is thus completed and the ice making cycle is completed, the process proceeds to step 114, and when the third timer 35 times out, the process returns to step 101 again, and thereafter this cycle is repeated to automatically make ice. If it is determined at step 107 that the ice making amount determination means 28 has a large ice making amount, the routine proceeds to step 114. In step 115, the motor driving means 30 stops the motor of the ice removing mechanism 21, and in step 116 the first timer 33 is started. In step 117, it is determined whether or not the first timer 33 has counted for a certain time, and the process waits until the time is up. When the first timer 33 expires in step 116, the process returns to step 103 and the ice detection operation is performed again.
