However, according to the above-mentioned conventional configuration, when the ice tray of the ice tray is set to rotate, if there is no signal from the detection mechanism of the full ice of the detectable refrigerator within a predetermined time, the refrigerator will be detected as a refrigerator. Not full of ice. Secondly, the solidity of the operating time of the ice-dipping motor, the temperature deviation, etc. may cause the above-mentioned signal to be unreceived within a predetermined time, and the full ice of the refrigerator cannot be detected. At this time, even if the ice cubes cannot be supplied to the refrigerator and the ice cubes are left in the ice tray, the water supply valve is supplied with water. Therefore, it is impossible to make ice cubes of a predetermined size, and the water will overflow and flow into the refrigerator in which the ice cubes are stored, resulting in melting of the stored ice cubes, and greatly degrading the quality of the ice cubes to the user. Become a problem.

The present invention solves the above-mentioned problems and aims to provide a refrigerator which can manufacture high quality ice cubes.

In order to solve the above problems, the refrigerator of one aspect of the present invention includes an ice making device, which is provided with: an ice making machine capable of making ice; and a refrigerator for pre-storing the ice made by the ice making machine. The ice making machine comprises: an ice making tray capable of receiving water supplied from the outside; and an ice discharging motor capable of rotating the ice making tray from the ice making tray after the water of the ice making tray has been frozen And the detecting portion is configured to detect a rotational position of the ice-carrying motor, and detect whether a frozen state of a predetermined amount or more of ice has been stored in the refrigerator; the refrigerator further includes a control unit When the power is turned on, the ice pump is rotated by the ice making tray, and the time before the signal from the detecting unit is changed is measured, and the operating time of the ice pumping motor is corrected by the measured time.

According to this configuration, when the power is turned on, the ice pumping motor can be rotated to measure the time before the signal of the detecting unit is changed, and the operating time of the ice pumping motor can be corrected. Here, when the ice pumping motor rotates forward, if there is no signal from the detecting portion within a predetermined time, it is detected that the refrigerator is not full of ice, so the solidity of the operating time of the ice pumping motor, temperature deviation, etc. may result in the predetermined time. The above signal could not be received, and the full ice of the refrigerator could not be detected. That is, the signal of the ice tray position or the signal of the full ice may be misdetected. Therefore, the solid deviation of the ice-splitting motor within a predetermined time is measured in advance, and the operation time is corrected, so that the false detection of the detecting mechanism can be avoided, and high-quality ice can be manufactured.

Further, the present invention can be realized not only as the above-described refrigerator but also as a control method for controlling the aforementioned refrigerator. Moreover, the special processing included in the above control method can also be implemented as a program executable by a computer. Secondly, the aforementioned program can be distributed by means of a recording medium such as a CD-ROM and a transmission medium such as a network, and it goes without saying.

Form for implementing the invention

The refrigerator of one aspect of the invention includes an ice making device, which is provided with: an ice making machine capable of making ice; and a storage refrigerator capable of pre-storing ice cubes made by the ice making machine; the ice making machine comprises The ice making tray can receive the water supplied from the outside; the ice discharging motor can rotate the ice making tray and remove the ice cube from the ice making tray after the water of the ice making tray has been frozen; The detecting unit detects the rotational position of the ice-carrying motor and detects whether the ice storage state of the predetermined amount or more of ice is stored in the storage refrigerator; and the refrigerator further includes a control unit that can perform the ice-discharging when the power is turned on The motor rotates the ice making tray and measures the time before the signal from the detecting unit is changed, and corrects the operating time of the ice pumping motor by the measured time.

In this way, the control unit can rotate the ice pumping motor when the power is turned on, measure the time before the signal of the detecting unit changes, and correct the operating time of the ice pumping motor. Here, when the ice-splitting motor rotates forward, if there is no signal from the detecting portion within a predetermined time, it is detected that the refrigerator is not full of ice, so the solid and temperature deviation of the operating time of the ice-splitting motor may cause misdetection of the ice tray. The signal of the location or the signal of the full ice. Therefore, by detecting the solid deviation of the ice-splitting motor for a predetermined time in advance and correcting the operation time, the detection unit can be prevented from being misdetected.

Thereby, the water supply valve is not supplied from the water intake valve in the state where the ice cube remains in the ice tray, so that it is possible to supply water to the ice tray after the ice is dialed. Therefore, it is possible to make ice cubes of a predetermined size, and the water does not flow into the refrigerator in which the ice cubes are stored, so that the stored ice cubes are not melted, so that high-quality ice cubes can be produced.

Further, the control unit preferably measures a time period from the start of the operation of the ice pumping motor until the detecting unit detects that the ice has not been filled as the time before the signal change, and corrects the detecting unit to detect that the ice has been filled with the measured time. Time is the operating time of the aforementioned ice pumping motor.

In this manner, the control unit can measure the time from the start of the operation of the ice-pumping motor to the time when the detecting unit detects that the ice has not been completed, and corrects the time at which the detecting unit detects that the ice has been full with the measured time. In other words, when the correction detecting unit detects that the ice has been full, the detecting unit can correctly detect the full ice state. Therefore, it is possible to avoid the false detection of the detecting portion and to make high quality ice.

Further, the refrigerator of the present invention further includes a freezer compartment temperature sensor capable of detecting the temperature of the freezer compartment formed inside the refrigerator, and the control unit preferably further makes the above-described system by the above-described ice-carrying motor before the operation of the ice-carrying operation. The ice tray is rotated, and the time before the signal change from the detecting portion is measured, and the operating time of the ice pumping motor is corrected by the measured time and the value measured by the freezing chamber temperature sensor.

In this way, the control unit can rotate the ice pumping motor to measure the time before the signal of the detecting unit is changed, and correct the operating time of the ice pumping motor according to the value measured by the freezer temperature sensor. Here, when the ice pump is rotated forward, if there is no signal from the detecting unit within the predetermined time, it is detected that the refrigerator is not full of ice, so the solidity of the operating time of the ice pump, temperature deviation, etc. may cause misdetection. The signal of the ice tray position or the signal of the full ice. Therefore, the temperature deviation within the predetermined time of the ice pump motor is measured in advance, and the operation time is corrected to avoid the false detection of the detecting portion.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The freezer compartment doors 12 and 13 are box doors for the freezer compartment provided in front of the refrigerator body 11, the freezer compartment door 12 is the box door on the left side, and the freezer compartment door 13 is the box door on the right side. In addition, in the figure, the open state of the freezer compartment door 12 is shown.

The operation substrate 14 is disposed on the operation substrate at the left end of the freezer compartment door 13 .

The freezer compartment temperature sensor 15 is a sensor that can detect the temperature of the freezer compartment formed inside the refrigerator 10, and is provided near the center of the freezing compartment. Further, the in-tank lamp 16 is an in-tank lamp that is disposed on the side wall of the freezer compartment in the refrigerator main body 11 box and can be illuminated inside the box.

The ice making device 20 is an ice making device that is disposed on the freezer compartment door 12. The ice making device 20 can supply tap water from the water injection port 19 via the water tank 17, the water intake valve 17a, and the water pipe 18. Here, the ice making device 20 includes an ice maker 21 that can automatically make ice, and a refrigerator 22 that can pre-store ice cubes made by the ice maker 21. The detailed structure of the ice maker 21 will be described later.

Further, the configuration of the door of the refrigerator 10 is representative of the nature and is not limited to such a configuration.

Hereinafter, the operation and function of the refrigerator 10 as described above will be described.

Fig. 2 is a structural view showing the structure of the ice maker 21 provided in the refrigerator 10 of the first embodiment of the present invention.

As shown in the figure, the ice maker 21 includes an ice tray 31, an ice pumping motor 32, a detecting unit 33, and an ice storage amount detecting lever 34.

The ice tray 31 is a tray that can receive water supplied from the outside. Specifically, once the water intake valve 17a is opened, water can be injected from the water injection port 19 through the water supply pipe 18 toward the ice making tray 31.

That is, the water intake valve 17a is disposed at one end of the tap that directly passes through the tap water, and the other end is connected to the tap water pipe 18 of the water injection port 19, and the predetermined water amount can be injected from the water injection port 19 toward the ice making tray 31.

The ice pumping motor 32 is connected to the ice making tray 31. When the water in the ice making tray 31 is frozen, the ice making tray 31 is rotated, and the homemade ice tray 31 is set to remove the ice. Specifically, after determining that the water in the ice making tray 31 has frozen, the ice making motor 32 can perform the forward rotation of the ice making tray 31, and perform the action of peeling off the ice in the ice making tray 31, and then borrow The rotation is reversed to return the ice tray 31 to the horizontal position.

The detecting unit 33 is mounted in the ice pumping motor 32, and is a position detecting mechanism that can detect the position of the ice making tray 31. Specifically, the detecting unit 33 can detect the rotational position of the ice pumping motor 32 and detect whether or not the full ice state in which the ice cubes of the predetermined amount or more are stored in the refrigerator 22 has been formed.

The ice storage amount detecting lever 34 is movable in synchronization with the rotational position of the ice pumping motor 32, and is moved between the (1) position and the (2) position of the figure. Specifically, when the ice in the refrigerator 22 is not full, the ice storage amount detecting lever 34 can be moved to the (1) position, and the detecting portion 33 does not detect the above-described full ice state. Further, when the ice in the refrigerator 22 is full, the ice storage amount detecting lever 34 is pushed back to the ice block before the position (1), so that the detecting unit 33 detects the full ice state.

Fig. 3 is a functional block diagram showing the functional configuration of a control mechanism provided in the refrigerator 10 of the first embodiment of the present invention.

As shown in the figure, the refrigerator 10 is provided with a control unit 41.

The control unit 41 is connected to the detecting unit 33, and the detecting unit 33 can detect whether the position of the ice making tray 31 and the ice in the refrigerator 22 are full.

Further, the control unit 41 can detect the temperature of the water icing in the ice making tray 31 by the freezing compartment temperature sensor 15, and cause the motor driving unit 43 having the function of operating the ice pumping motor 32 to make the ice pumping motor 32 positive. Turning, the ice in the ice tray 31 is peeled off. Further, the control unit 41 causes the motor drive unit 43 to cause the ice pumping motor 32 to perform the reverse operation until it is at the horizontal position.

Further, the control unit 41 can dial the ice cube of the ice tray 31 by the ice motor 32, and then the valve driving unit 44 that can perform the switching control of the water intake valve 17a can control the water supply to the water supply tray 31. The valve 17a is opened.

Next, the control unit 41 can rotate the ice tray 31 by the ice motor 32 when the power is turned on, and measure the time before the signal from the detecting unit 33 is changed, and correct the action of the ice pump 32 with the measured time. time. Specifically, the control unit 41 can measure the time from the start of the operation of the ice pumping motor 32 until the detection unit 33 detects that the ice has not been filled as the time before the signal change, and the detected time correction detecting unit 33 detects the full time. The time of ice is used as the operating time of the ice pumping motor 32.

Further, the control unit 41, the water intake valve 17a, and the ice pumping motor 32 are supplied with electric power such as the power source 42.

Fig. 4 is a flow chart showing an example of the operation of the control unit 41 of the refrigerator 10 according to the first embodiment of the present invention.

As shown in the figure, first, when the power is turned on, the control unit 41 rotates the ice tray 31 by the ice motor 32 (step S102).

Next, the control unit 41 measures the time until the signal from the detecting unit 33 is changed in accordance with the operation of the ice pumping motor 32 (step S104). In other words, the control unit 41 measures the time until the detection unit 33 detects that the operation of the ice pumping motor 32 has not been completed. In addition, the details of its time measurement are left to be described later.

Then, the control unit 41 corrects the operation time of the ice pumping motor 32 with the measured time (step S106). In other words, the control unit 41 detects the time when the detection unit 33 detects the full ice by the measured time. In addition, the details of the action time correction are left to be described later.

Hereinafter, the operation of the ice pumping motor 32 will be described based on the control flowchart of the ice maker 21 of the refrigerator 10. Fig. 5 is a flow chart showing the control of the operation of the ice pump 32 of the refrigerator 10 according to the first embodiment of the present invention.

Specifically, the figure shows the relationship between the operation of the ice-splitting motor 32 and the detection unit 33 in which the signal installed in the ice-splitting motor 32 corresponds to the position of the ice tray 31. Hereinafter, the position numbers (1) and (2) shown in the figure will be described.

The position number (1) indicates that the ice tray 31 is in the horizontal position, and the signal from the detecting portion 33 indicates "H".

If the water in the ice tray 31 freezes, the control unit 41 sends a signal to the ice pump 32 to forward the forward rotation according to the command from the motor drive unit 43, and the ice tray 31 starts the forward rotation operation. After that, the signal of the detecting unit 33 is changed to "L".

Next, if the ice in the refrigerator 22 is not full, the signal of the detecting unit 33 will be maintained at "L", and if the signal of the detecting portion 33 is changed to "L" → "H" at the position number (2) Then, the control unit 41 stops the forward rotation operation of the ice pumping motor 32. At this time, the ice tray 31 has been rotated by 180 degrees to be in an ice-discharging state, and the ice cubes in the ice tray 31 are dropped into the refrigerator 22.

Further, the control unit 41 can measure the time tx before the signal of the detecting unit 33 of the position numbers (1) to (2) is changed.

Then, the ice tray 31 receives an instruction to reverse the operation from the control unit 41. After the ice pump 32 has reversed the operation, the signal of the detecting unit 33 is changed to "H" -> "L".

Next, before the signal of the detecting unit 33 is changed to "L" → "H" again, the ice pumping motor 32 will maintain the reverse operation. If the position number (1) is changed to "L" → "H", then at t14 After the braking is performed during the period, the control unit 41 returns the ice tray 31 to the horizontal position by the ice motor 32, and stops the ice pump 32 within the period t12.

Hereinafter, the solid deviation correction characteristic of the operation time of the ice pump 32 will be described. Fig. 6 is a view showing the solid deviation correction characteristic of the operation time of the ice pumping motor 32 according to the first embodiment of the present invention.

There is a fixed deviation between the timing of the dialing motor 32 and the detecting unit 33, and the following correction value is added to avoid erroneous detection by the detecting unit 33. Hereinafter, the correction method will be described.

Based on the tx measurement result in Fig. 5, tm can be obtained from the characteristics shown in Fig. 6. That is, the figure shows that if tx = tx1, then tm = tm1, and if tx = tx2, then tm = tm2 has a positive characteristic. Here, tm is the period from the start of the operation of the ice pumping motor 32 until the detecting unit 33 detects the full ice.

Hereinafter, a control flow chart in which the solid deviation of the ice pump 32 of the refrigerator 10 has been corrected will be described with respect to the timing of tm. Fig. 7 is a flow chart showing the control of the operation of the ice pump motor 32 after the solid deviation correction according to the first embodiment of the present invention.

First, if the water in the ice tray 31 freezes, a signal of the forward rotation operation is sent to the ice pumping motor 32 in response to a command from the control unit 41 to the motor drive unit 43, and the ice pump 32 causes the ice tray 31 to start. In the forward rotation operation, after t14, the signal of the detecting unit 33 is "L".

Next, after the operation of the ice-carrying motor 32 is displayed and the signal of the detecting unit 33 is changed to "L" -> "H" within the period from the position number (3) to the time t21, the ice storage amount detecting lever 34 is used. The detecting unit 33 detects that the ice in the refrigerator 22 is full of ice. Therefore, the ice tray 31 is not turned down and the ice tray 31 is returned to the horizontal position, so the control unit 41 switches the ice pumping motor 32 to the reverse operation.

Then, before the signal of the detecting unit 33 is changed to "L" → "H" again, the ice pumping motor 32 will maintain the reverse operation. If the position number (1) is changed to "L" → "H", then at t14 After braking in the period, the control unit 41 transfers the ice tray 31 to the horizontal position by the ice motor 32, and stops the ice pump 32 within the period t12.

Here, although the period of t12 is a preset value, depending on the solid deviation of the ice pump 32, it is possible to change the signal of the detecting unit 33 to "L" → "H" at the position number (3). It takes time tm. That is, when t21 < tm, the detecting unit 33 cannot detect the full ice, and mistakes the position number (3) as the position number (2), and causes the ice pumping motor 32 to be erroneously reversed. At this time, the ice tray 31 is returned to the horizontal position at the position number (1), and even if ice cubes remain in the ice tray 31, the water supply valve 17a is supplied with water.

Therefore, according to the solid deviation correction characteristic of the operation time of the ice-carrying motor 32 shown in FIG. 6, when the tx measured when the power is turned on is tx1, the control unit 41 can be corrected to the value after t21 by tm1. Take control. Thereby, it is not affected by the solid deviation of the ice-carrying motor 32, and full ice can be detected on the position number (3).

As described above, according to the refrigerator 10 of the first embodiment, when the power is turned on, the ice pumping motor 32 can be rotated to measure the time until the signal of the detecting unit 33 is changed, thereby correcting the operation time of the ice pumping motor 32. Here, when the ice motor 32 is rotated forward, if there is no signal from the detecting unit 33 within a predetermined time, it is detected that the refrigerator 22 is not full of ice, so the solid deviation of the operating time of the ice pump 32 will cause misdetection. The signal of the ice tray position or the signal of full ice. Therefore, the solid deviation of the ice-splitting motor 32 for a predetermined time is measured in advance, and the operation time is corrected, so that the false detection by the detecting portion 33 can be avoided.

Specifically, the control unit 41 can measure the time from when the operation of the ice pumping motor 32 is started until the detection unit 33 detects that the ice has not been completed, and corrects the time when the detected time is detected by the detected time detecting unit 33. In other words, when the correction detecting unit 33 detects the time of full ice, the detecting unit 33 can accurately detect that the ice is full, so that the detection unit 33 can be prevented from being erroneously detected.

Thereby, water is supplied from the water intake valve 17a in a state where ice cubes remain in the ice tray 31, so that water supply to the ice tray 31 after ice plucking can be surely performed. Therefore, it is possible to produce ice cubes of a predetermined size, and the water does not flow into the refrigerator 22 in which the ice cubes are stored, so that the stored ice cubes are not melted, so that high-quality ice cubes can be produced.

(Second embodiment)

In the second embodiment, the control unit 41 can further correct the operation time of the ice pumping motor 32 by using the value measured by the freezing compartment temperature sensor 15. That is, the control unit 41 can rotate the ice tray 31 by the ice motor 32 before the ice-carrying operation, and measure the time before the signal change from the detecting unit 33, and sense the time and the freezing chamber temperature measured. The value measured by the device 15 corrects the operating time of the ice pumping motor 32.

Fig. 8 is a view showing the temperature characteristics of the operating time of the ice pumping motor 32 according to the second embodiment of the present invention.

Fig. 9 is a view showing the temperature deviation correction characteristic of the operation time of the ice pumping motor 32 according to the second embodiment of the present invention.

The time tx of the position numbers (1) to (2) in the control flow chart of the ice pump motor 32 of the refrigerator 10 of the first embodiment shown in Fig. 5 is measured by the freezer compartment temperature sensor 15. It changes with temperature.

In Fig. 8, tx4 at -20 degrees and tx3 at 25 degrees show the characteristics of the value change.

Therefore, each time the freezing compartment temperature sensor 15 detects the predetermined temperature, the control unit 41 measures the value of tx based on the characteristics shown in the figure and the control flowchart of the ice pump 32 shown in FIG.

Next, by using the temperature deviation correction characteristic of the operation time of the ice pump 32 shown in FIG. 9, the correction value of the temperature deviation can be added to the timing of the ice pump 32 and the detecting unit 33, thereby avoiding the false detection by the detecting unit 33. , the following, it explains its correction method.

That is, based on the measurement result of tx, tm can be obtained from the characteristics shown in Fig. 9. The figure shows that tm = tm3 if tx = tx3, and tm = tm4 if tx = tx4. Here, as in the sixth drawing, tm is the period from the start of the operation of the ice pumping motor 32 until the detecting unit 33 detects the full ice.

Next, a control flow chart after the temperature deviation correction of the ice pump 32 of the second embodiment of the present invention in Fig. 10 will be described with respect to the timing of tm. Fig. 10 is a flow chart showing the control of the operation of the ice pump motor 32 after the solid deviation correction according to the second embodiment of the present invention.

First, if the water in the ice tray 31 freezes, a signal of the forward rotation operation is sent to the ice pump motor 32 in response to a command from the control unit 41 to the motor drive unit 43, and the ice pump 32 causes the ice tray 31 to start. The forward rotation operation is performed, and after t14, the signal of the detection unit 33 is "L".

Next, after the operation of the ice pumping motor 32 is displayed and the signal of the detecting unit 33 is changed to "L" → "H" within the period from the start of the position number (3) to the period t21, the ice storage amount detecting lever 34 can be used for detection. The portion 33 detects that the ice in the refrigerator 22 is full of ice. Therefore, in order to return the ice tray 31 to the horizontal position without dropping the ice cubes of the ice tray 31, the control unit 41 switches the ice pumping motor 32 to the reverse operation. Next, before the signal of the detecting unit 33 is changed again from "L" to "H", the ice pumping motor 32 will maintain the reverse operation. If the position number (1) is changed to "L" → "H", then at t14 After braking in the period, the control unit 41 returns the ice tray 31 to the horizontal position by the ice pump 32, and stops the ice pump 32 within the period t12.

Here, although the period of t12 is a preset value, depending on the solid deviation of the ice pump 32, it is possible to change the signal of the detecting unit 33 to "L" → "H" at the position number (3). It takes time tm. That is, when t21 < tm, the detecting unit 33 cannot detect the full ice, and mistakes the position number (3) as the position number (2), and causes the ice pumping motor 32 to be erroneously reversed. At this time, the ice tray 31 is returned to the horizontal position at the position number (1), and the water is supplied from the water intake valve 17a even if the ice tray 31 remains in the ice tray 31.

Therefore, according to the temperature deviation correction characteristic of the operation time of the ice pump 32 shown in FIGS. 8 and 9, when the value measured by the freezer temperature sensor 15 is -20 degrees, tx will be tx4, so control The portion 41 can be controlled by correcting t21 to a value of tm4. Thereby, it is not affected by the temperature deviation of the ice-carrying motor 32, and full ice can be detected on the position number (3).

As described above, according to the refrigerator of the second embodiment, the ice pumping motor 32 can be rotated to measure the time before the signal of the detecting unit 33 is changed, and the value measured by the freezer temperature sensor 15 can be corrected. The operating time of the ice motor 32. Here, when the ice motor 32 is rotated forward, if there is no signal from the detecting unit 33 within a predetermined time, it will be detected that the refrigerator 22 is not full of ice, so the temperature deviation of the operating time of the ice pump 32 will cause an error. Measure the signal of the ice tray position or the signal of the full ice. Therefore, the temperature deviation within the predetermined time of the ice pumping motor 32 is measured in advance, and the operation time is corrected, so that the erroneous measurement by the detecting portion 33 can be avoided.

Thereby, the water supply from the water intake valve 17a is not performed in a state where the ice cubes remain in the ice tray 31, so that the ice tray 31 after the ice is supplied can be surely supplied with water. Therefore, ice cubes of a predetermined size can be formed, and the water does not flow into the refrigerator 22 storing the ice cubes, so that the stored ice cubes are not melted, so that the user can maintain the supply of high-quality ice cubes.

Although the refrigerator of the present invention has been described above based on the embodiments, the present invention is not limited to the above embodiments.

That is, the embodiments disclosed above are considered to be illustrative in nature and not limiting in nature. The scope of the present invention is defined by the scope of the claims, and is intended to cover all modifications within the meaning and scope of the claims.

For example, the present invention can also be implemented as a control method for controlling a refrigerator. Moreover, the special processing included in the above control method can also be implemented as a program executable by a computer. Secondly, the above program can be distributed by means of a recording medium such as a CD-ROM and a transmission medium such as a network, and it goes without saying.

Industrial availability

The refrigerator of the present invention can be applied to ice cubes of a predetermined size, and the water does not flow into the refrigerator in which the ice cubes are stored, so that the stored ice cubes are not melted, so that high-quality ice cubes can be maintained for the user. The refrigerator provided can also be applied to other system control such as a kitchen storage box equipped with an ice making device and various storage boxes in conjunction with other machines.
