Abstract

PURPOSE: To enable control of performance of an ice-making apparatus properly in cooperation with the specification different from each other of ice-making devices, by judging a specification from performance signals of the ice-making machine to control the operation of the apparatus on the basis of the results of the judgment. CONSTITUTION: By applying power an ice-making pan is made to assume a horizontal position and the water in the pan freezes completely, when an ice- making completion temperature detective means 2 detects the completion of the ice making. After the detection the ice in the ice-making pan is separated by rotating the ice-making pan by means of a driving motor 7. Ice-making performance signals from positions swA10, swB11 corresponding to the turning angles of the driving motor 7 to separate the ice are outputted from the ice- separating unit 5. On the basis of the outputs a performance-judging device 14b of the control unit 14 judges the manner in which the ice is separated in the ice-separating unit 5 and on the basis of the results of the judgment a controller 14 controls the driving voltage applied to the driving motor 7. This method enables controlling the performance of an ice-making apparatus properly in the way adapted to the manner of performance peculiar to this apparatus.

【Example】

Example 1. Embodiment 1 of the present invention will be described below with reference to FIGS.
This will be described using 9. FIG. 3 shows the first example of the first embodiment.
Diagram showing an automatic ice machine installed in a refrigerator with the specifications of
FIG. 4 is a block diagram showing an automatic ice maker provided in a refrigerator of the second specification according to the first embodiment, FIG. 1 is a flowchart of a subroutine for judging the specifications of the automatic ice maker, and FIG. It is a flowchart figure which shows operation | movement of this automatic ice maker. The same components as those of the conventional one are designated by the same reference numerals, detailed description thereof will be omitted, and only different portions will be described. In FIG. 3 and FIG. 4, 14b is a specification determination device, which is a part of the operation signal of the ice making device, and indicates the specifications of the ice making device by the ON / OFF signal from the position swA10 or the position swB11 which is the ice removing operation signal. The specifications of a part of the ice removing mechanism are determined. In addition,
The control unit 14 which is the control device of the present invention uses the same name code as that of the conventional embodiment, but as will be described later, the ice making device corresponding to the specifications of each ice making device based on the determination result of the specification determining device 14b. It controls the operation of.

Next, the operation will be described with reference to FIGS.
This will be described with reference to the flowchart of FIG. First, when the power is turned on, the operation of returning the ice tray 1 to the horizontal position is performed in the origin return routine of step 100 (hereinafter step is abbreviated as S). (Details of this operation will be described later) Next, in S201, the ice tray 1 is kept horizontal until the ice making is completed.
As a result of this waiting, when the water in the ice tray 1 is completely frozen and the ice making completion temperature detecting means 2 detects, for example, −12 ° C. or lower, it is determined in S201 that the ice making is completed, and the process proceeds to S202, where the drive motor 7 is turned on. After resetting the timer A that counts the rotational drive time, the drive motor 7 is started in the normal rotation in S203, and the timer A starts counting the normal drive time in S204. The drive motor 7 starts forward rotation, and
As shown in (full ice detection) or FIGS. 8i and 9i (ice removal detection), when swA is turned on, YES is determined in S205, timer A is stopped in S206, and S207 is performed.
The drive motor 7 is stopped with. Then, in the origin return routine S100, the drive motor 7 is reversely driven to return the ice tray 1 to the horizontal position.

At the next step S208, the drive motor 7 is operated at step S20.
This is a step of determining whether the position stopped at 7 is the full ice detection position (FIGS. 8d and 9d) or the ice removal detection position (FIGs. 8i and 9i). That is, S204 to S206
In the steps up to, the time counted by timer A is 10
If it is more than a second, the drive motor 7 is normally rotated to the ice separation detection position, and the ice making tray 1 is returned by the origin return routine S100.
Determines that the ice has completed the ice removal and has returned to the horizontal position, and in order to supply water to the ice tray 1 that has returned to the horizontal position, S209, S210,
In S211, the water supply pump 13 is turned on for 10 seconds to perform the water supply operation, and when the water supply is completed, the process returns to S201 again, and the same operation is repeated. On the other hand, if NO in S208,
That is, when the time counted by the timer A is less than 10 seconds, the drive motor 7 is normally rotated to the full ice detection position, and it is determined by the origin return routine S100 that the ice tray 1 has returned to the horizontal state without releasing ice. Then, in S212 to S214, ice-waiting is waited until one hour has passed, and then the process returns to 201 after waiting.

In the forward rotation operation of the drive motor 7 up to S205, the ice detecting lever 3 is also engaged with the pin 9a of the cam gear B9. Therefore, as shown in FIG. However, the drive motor 7 is reversely rotated by the origin return routine S100, which will be described later, and when the ice detecting lever 3 is descending due to this reverse rotation, the engagement with the pin 9a is released, and the cam gear B9 is disengaged only via the spring 9b. Since they are connected, the ice detection lever 3 is prevented from descending if it hits the ice in the ice storage box 4. Therefore, the ice detection position (d in FIGS. 8 and 9)
It is determined whether the inside of the ice storage box 4 is full ice or empty ice from the rotation position (rotation angle) of the ice detection lever 3 in f). When the rotation angle of the cam gear B9 is θ ₁ = 40 ° and the rotation angle θ ₂ of the ice detecting lever 3 is 0 ° ≦ θ ₂ <30 °, swA is turned on and the drive motor 7 is rotated normally. Time, ie timer A
Since the time to count is about 3 seconds, full ice is detected in S208. The rotation angle θ ₂ of the ice detection lever 3 is 30 °.
If ≦ θ ₂ <40 °, it is determined to be empty ice. Also, s
wA does not turn on in the range of d f in FIG. 8 and FIG.
Since it is turned on at i in FIG. 9, the time until swA is turned on, that is, the time counted by the timer A is about 15 seconds. Therefore, in S208, the drive motor 7 is normally rotated to the ice removal detection position, and the ice is empty. It is determined that the ice in the ice tray 1 has been released. In addition, at the time of h in FIG. 8 and FIG.
Since the rotation of one end of the ice tray 1 is blocked at 150 °, the other end rotates to 170 ° and is twisted, so that the ice of the ice tray 1 falls into the ice storage box 4. The ice removal is completed.

Next, the operation of step 100 will be described with reference to FIGS. 1, 10 and 11. First, S120
In order to return the ice tray 1 that has been normally rotated in
Reverse the drive motor 7. Whether the automatic ice maker operating in the steps after S121 has the first specification or the second specification while the specification determination device 14b reads the ON / OFF signal of the position swA (10) and the position swB (11). Since the determination is made, the details of the operation will be described. First, in the case where the ice removing mechanism 5 of the first specification is adopted, in FIGS. 1 and 10, the control means 14 turns off the double-pole double-throw relay 33, and the reverse contact 33b is connected to the positive side of the power source 34. After the connection, when the single pole single throw relay 32 is turned on, the current I flows in the direction shown in FIG.
Starts the reverse rotation operation (the above is the operation of S120). As shown in FIG. 5 or FIG. 8, when the motor 7 rotates in the reverse direction, the position swA10 of the ice removing mechanism 5 of the first specification is continuously 3 times.
Since it does not turn on for more than a second, the ice tray 1 is horizontal (Fig. 8
When the position swB (11) is turned on, the answer is YES in S121, and the motor 7 is stopped in S126 and S127.

Next, when the ice removing mechanism 5 of the second specification is adopted, in FIG. 1 and FIG. 11, the control means 14 turns off the double pole double throw relay 33, and the reverse contact 33b of the power source 34 is used. When the single-pole single-throw relay 32 is turned on after being connected to the plus side, the current I flows in the direction shown in FIG. 11, and the motor 7 starts the reverse rotation operation (the operation of S120 above). The ice removing mechanism 5 of the second specification has the position s as shown in FIG.
Since wB is not provided, the position swB
Is never turned on, so that it is always NO in S121 and YES in S122. That is, the position where the position swA10 is turned on when the motor 7 rotates in the reverse direction is in the range of f → d and b → a in FIG. However, ON in the range of f → d
However, since the duration of ON is less than 1 second, the time counted by the pulse timer in S124 is less than 1 second, and NO is determined in S125.
1, S122 is also determined to be NO, and the time counted by this pulse timer is reset for 1 second in S123.

The condition for YES in S125 is shown in FIG.
Between b → a in the middle, or only when the cam gear A8 is mechanically locked at the time of reverse rotation drive (hereinafter abbreviated as per degree), that is, when it is locked for 3 seconds at the position of a per degree, Therefore, after YES in S125, S126
Reset the pulse timer with, and drive motor 7 with S127.
Then, the ice tray 1 stops at the horizontal position.

When it is determined that the specifications are the first specifications based on the determination result, the ice removing mechanism 5 is determined based on the determination result.
The voltage V _M applied to the drive motor 7 is controlled at 12 V both in forward rotation and in reverse rotation.
If it is determined that it is the specification of, based on this determination result,
As shown in FIG. 12, the voltage V _M applied to the drive motor 7 of the ice removing mechanism 5 is controlled to be different between the forward rotation and the reverse rotation. That is, the constant of the resistor 30 is set so that the voltage V _M applied to the drive motor 7 and the voltage V _R applied to the resistor 30 in the normal rotation have a ratio shown in “during reverse rotation” in FIG. There is. That is, the diode 31 is connected in parallel to the resistor 30, and the current I when the drive motor 7 is normally rotated flows in the direction opposite to the direction indicated by the arrow in FIG.
Forward drop voltage V _R is approximately 0.7V next diode 31, since the drive motor 7 is 12V-0.7V = 11.3 V is applied, the torque required to twist the ice tray 1 during an ice removal Can be generated. Further, at the time of reverse rotation, the voltage applied to the drive motor 7 is approximately equal to the torque required to operate the cam gear A8, the cam gear B9, and other gear trains (not shown). 2V or more, and as shown in FIG. 20, unless the applied voltage to the drive motor 7 is about 5V or less in the hit state of FIG. 9a, the cam gear A8, the gear train (not shown), etc. Due to the repeated and repetitive mechanical stress due to the repeated lock of these parts, the parts are damaged, and this automatic ice making machine becomes unusable for practical use, V _M is controlled within the range of 2V ≦ V _M ≦ 5V. Is good. Therefore, the voltage applied to the drive motor 7 during reverse rotation is controlled to be approximately 3.0V.

Example 2. In the first embodiment, the ice tray 1
Was operated based on the specification of the automatic ice maker as a result of the determination every time the is rotated to the horizontal position, the specification of the automatic ice maker as the result of the determination is stored, and as shown in FIG.
It is held as data in 128 or S129, and this data is utilized in S300 and S301 in FIG. 14 to determine whether the specifications of the automatic ice making machine judged this time are different from the specifications of the automatic ice making machine judged last time, and if there is a change. In this case, by determining whether the specifications have changed again, it is possible to prevent misjudgment of the ice making specifications caused by external noise, etc. It is possible to obtain a highly reliable controller for an automatic ice maker that accurately controls the ice making operation even when the device is incorporated.

Example 3. In the second embodiment, the ice-breaking specification of the automatic ice maker is used as data to prevent malfunction due to noise or the like. However, as shown in FIG.
According to each specification, for example, if the driving time of the drive motor 7 is set to 14 seconds, the twist angle of the ice tray can be stopped at 160 °, so that the ice making can be performed regardless of the specifications. It is possible to control the rotation angle of the dish.

In the above-mentioned Examples 1 to 3, the ice tray 1
The specifications of the ice removing mechanism of the automatic ice maker were determined by using the difference in the horizontal position detection method of the ice making machine. In the case of the specifications, each of the different operation times is determined, that is, the specification of each ice removing mechanism is determined by the ice removing operation signal of the ice removing mechanism that is the ice making operation signal of the ice making device. However, the same effect is obtained.

In the first to third embodiments described above, the ice removing operation signal of the ice removing mechanism is used as the operation signal of the ice making device. However, the ice making operation signal of the ice making device, for example, the ice making operation signal of the ice making device is used. When the ice making completion temperature which is the signal of the ice making operation is different from each other (for example, -12 ° C and -5 ° C), the ice making completion temperature signals different from each other are used as the ice making operation signal of the ice making unit. From the ice making completion temperature signal, the specification determining device 14b determines the ice making specifications of the ice making unit, which is a part of the ice making specifications of the ice making device, and the control device 14 controls the operation of the ice making device based on the result of this determination. Produce the effect of. Since the ice making operation signal of the ice making unit and the ice making operation signal of the ice removing mechanism that are part of the operation signal of the ice making device generally operate in conjunction with each other, the ice making operation signal of the ice making unit is It goes without saying that the specifications of the ice removing mechanism can be determined.

[0031]
