Description

TECHNICAL FIELD [0001] The present invention relates to a twist ice maker and a refrigerator including the twist ice maker.

An embodiment of the present invention relates to a twisted ice maker and a refrigerator including the twisted ice maker.

Generally, a refrigerator has a main body having a refrigerating chamber for refrigerating and storing foods and a freezing chamber for refrigerating and storing food, and a compressor for compressing the refrigerant and a heat exchanger for generating cold air are installed at the rear of the main body. The cold air generated by the heat exchanger is supplied to the refrigerator compartment or the freezer compartment by the fan and circulated in the refrigerator compartment or the freezer compartment to supply the heated air to the refrigerator compartment or the freezer compartment through the heat exchanger. State. At this time, an ice maker for producing ice is installed in the freezing room or the refrigerating room.

The ice maker provided in the refrigerator automatically supplies water to the ice maker and checks the ice making condition, and when the ice maker is finished, the ice cubes are automatically released from the ice maker to be loaded on the ice maker. It is widely used in recent years because it can obtain ice without any special operation.

These ice makers are of the type that includes the ejector and the heater and the type that twist the tray to freeze the ice. In the type of ice maker that twists the tray, the energy efficiency is higher than the type including the ejector and the heater because the heater is not used. In the case of a type of twisting the tray, it is necessary to twist the tray and return it to the original position. For this purpose, the motor uses a direct current (DC) motor. Conventionally, a brush motor is used as a DC motor for a long time.

However, in the brush formed of carbon used for the brush motor, dust is generated over time. As a result, there is a limit to the service life of the brush motor itself, and contamination by dust is generated around the brush motor (inside the refrigerator). In addition, noise and vibration generated in the brush motor itself are serious, and the user may feel uncomfortable during operation. In addition, the amount of current consumed during operation of the brush motor is high and the heat generated by the brush motor is high, which results in a decrease in energy efficiency.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is an exemplary embodiment only and the present invention is not limited thereto.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are merely a means for efficiently describing the technical idea of the present invention to a person having ordinary skill in the art to which the present invention belongs.

Hereinafter, various embodiments will be described below. In each embodiment, an embodiment including at least one of a control unit, a signal transmission unit, a cross output unit, a signal reception unit, and a driver unit will be described below.

The control unit, the signal transmitting unit, and the cross output unit may be located on the refrigerator side, and the icemaker may include a signal receiving unit, a driving unit, and the like. Since the signal transmission unit and the cross output unit are located in the refrigerator, the ice maker can receive the control signal from the refrigerator.

The drive motor to be described later may be a stepping motor. Further, it may be a stepping motor and a geared motor. That is, a geared portion is provided in the case of the stepping motor, so that the rotational speed and the torque can be increased or decreased compared with the conventional numerical value. Specifically, a plurality of gears are provided on the side where the motor shaft extends from the drive motor, and the speed ratio is adjusted to increase or decrease the rotation speed of the drive motor. Of course, since the number of revolutions and the torque can be inversely proportional, a person skilled in the art can determine the gear ratio of the driving motor in consideration of the number of revolutions and torque. By employing the drive motor, it is not necessary to secure a space for providing a separate gear structure in the ice-maker for deceleration or torque control. Accordingly, it is possible to prevent malfunctions and faults generated from separate gears in advance.

On the other hand, as a convenience for explaining the features of the present invention, a case where a stepping motor is employed will be described below as an example.

1 is a sectional view of an ice maker 10 according to a first embodiment of the present invention.

Referring to FIG. 1, the ice maker 10 may be disposed in a space having a refrigeration temperature of the refrigerator. The icemaker 10 may include a driving unit 20 and an eyestra 30.

The ice stalks 30 may include an ice making space 35 for receiving de-iced water therein. A plurality of partition walls are formed in the interior of the ice tray 30 to separate the ice making space 35 into a plurality of spaces. The ice stray 30 may be provided with a temperature sensor unit 37 for measuring the temperature of the ice making water. In addition, a capacitance sensor 36 may be provided to sense the amount of ice-making water contained in the ice-making space 35.

The eye stray 30 may be formed of a resin material and may be twisted by the driving unit 20 and then returned to its original shape.

The driving unit 20 may be provided on one side of the icestray 30. [ The driving unit 20 can twist the icemaker 30 to freeze the ice cubes in the icemaker 30. [ For this purpose, the driving unit 20 may include a structure for rotating the icestra 30. [

For example, the driving unit 20 may include a driving motor 21, a gear unit 24, a casing unit 26, and an output unit 25. The drive motor 21 can provide a rotational force for rotating the eye straighter 30. [ The drive motor 21 can generate a predetermined rotation speed. The drive motor 21 may be a stepping motor. Since the stepping motor rotates by a certain angle every time a pulse signal is applied, the number of input pulse signals is proportional to the rotation angle of the motor. Therefore, the rotation angle of the motor can be accurately controlled by controlling the input pulse.

When the brush motor is used as the motor, the life of the brush formed of carbon is limited, and the periphery of the motor may be contaminated by the carbon powder generated in the carbon brush. Further, noise and vibration generated by the brush motor are large, and the current consumed during operation of the brush motor may be high. In addition, the temperature generated by the brush motor may increase significantly, resulting in a large energy consumption. On the other hand, the current consumed by the stepping motor is low, and noise and vibration during operation are small. In addition, the heat generated during the operation of the stepping motor is low, so that the energy efficiency is high. Also, since there is no carbon brush, there is no contamination caused by carbon powder, and the service life is semi-permanent.

On the other hand, "21a" in FIG. 1, which is not described, is a film-type power supply unit 21a provided to supply power to the drive motor 21.

The ice maker 10 may include a position sensor (not shown) for detecting the rotational position of the eye strainer 30 by the drive motor 21. [

The gear portion 24 may reduce the rotation speed of the rotation generated in the drive motor 21 and increase the torque. An auxiliary gear 22 may be formed on the shaft 23 of the drive motor 21. [ The auxiliary gear 22 can increase the torque of the rotation generated in the drive motor 21 before the gear portion 24 so that the torque of the rotation generated in the gear portion 24 can be further increased.

The gear portion 24 is connected to an ice-full sensing lever (not shown) to twist the ice-strainer 30 as well as the amount of ice generated in the icemaker 10 and stored in an ice reservoir Can also be performed.

The output unit 25 can be connected to the iostula 30 to output a rotational force having a reduced rotational speed and an increased torque by the gear unit 24 to the iestray 30 side.

The casing unit 26 may have a driving motor 21 and a gear unit 24 disposed therein and a through hole may be formed so that the output unit 25 can be connected to the icestray 30. [ At least one of the light emitting portion and the light receiving portion may be positioned on one side of the casing portion 26 to detect the fullness of ice stored in the ice reservoir located below the casing portion 26. [ That is, the light emitting unit and / or the light receiving unit located in the casing unit 26 can detect whether or not the ice is full according to the degree of reflection of light reflected on the ice.

The icicle 30 can be twisted by the rotational force generated in the driving unit 20. [ In order for the eye stray 30 to be twisted, one side of the eye stray 30 stops at a state rotated by a predetermined rotation distance, and the other side of the eye stray 30 can rotate more than the predetermined rotation distance. Thus, the rotation distances of both sides of the eye stray 30 are different from each other, so that the eye straighter 30 can be twisted.

A motor control unit (not shown) for controlling the driving motor 21 can be located in the icemaker 10 or in the refrigerator. (Not shown) disposed on one side of the drive motor 21 when the motor control unit is located in the icemaker 10. [ Since the driving motor 21 is a stepping motor, the motor control unit can control the driving motor 21 by receiving the control waveform. Further, a position signal by the drive waveform of the drive motor 21 can be supplied to the motor control section. Accordingly, the motor control unit can accurately control the rotational position of the drive motor 21. [ The motor control unit may be a driver for generating a pulse signal for driving the driving motor 21. [

The stepping motor, which is the drive motor 21, is capable of both forward and reverse rotation. Therefore, it is possible to twist the icestra 30 only by the drive motor 21 and return it to its original position. However, the present invention is not limited to this. The twist of the eyestra 30 can be achieved by driving the motor 21 and bringing the eyestra 30 back in position. The elastic member (not shown) mounted on one side of the eyestra 30 ).

2 and 3 are views for explaining the operation of the ice maker according to the second embodiment of the present invention.

2 and 3, the icemaker 10 includes a signal transmission unit 500, a cross output unit 300, a signal reception unit 400, a driving unit 100, and an eye strainer 200, which transmit the electric signal 1, . ≪ / RTI >

Specifically, the signal transmitter 500 may transmit the electric signal 1 to drive the driving unit 100 according to the information contained in the electric signal 1. The electric signal 1 received from the signal transmitting unit 500 may be transmitted to the signal receiving unit 400 via the cross output unit 300. The direction of transmission may determine the operation information of the driving unit to which the electric signal 1 is finally transmitted to the electric signal.

Furthermore. The information contained in the electrical signal 1 is transmitted in a different pps (pulse per second) when the electrical signal is transmitted in a pulse form, and each pps (pulse per secomd) may include specific information. For example, when the signal is transmitted at 180 pps, when the signal is transmitted at 500 pps in forward rotation, the driving unit may be driven in the reverse direction. As described above, not only the information related to the rotation direction but also information including the rotation angle and the torque.

In the case of digital signals of 0, 1, -1, etc., the rotation speed, the rotation direction, the rotation angle, the torque, and the like can be determined as a result of signal combination transmitted for each of a plurality of signal lines. That is, the electrical signal may be in bipolar form. Of course, it can be a unipolar type. For example, even in the case of a digital signal which is a signal of 1, 0, the rotational speed, the rotational direction, the rotational angle and the torque can be determined through the combination of the respective signals. That is, the electric signal may be applied to one or more of bipolar and unipolar.

Of course, the information such as the rotational direction, the rotational angle, the rotational speed, and the torque may be determined according to the above-described information, or may be determined according to the electric signal 1 transmitted in the crossing output section 300 as in the present embodiment have. That is, it can be determined according to information such as the type of information intersected by the cross output unit 300, the intersection time, and the number of intersections. The signal receiving unit 400 or the drive 110 receiving the electrical information 1 transmitted by the crossover output unit 300 to convert the information into the rotation information may record data of predetermined periodical information, It is possible to perform processing to switch to rotation information when the mobile station 1 is received.

The electric signal 1 transmitted from the crossover output unit 300 may be received by the signal receiving unit 400 and then transmitted to the driving unit 100. The driving unit 100 may be driven by receiving the electric signal. Here, the driving unit 100 may include a drive 110 and a driving motor 120. The drive 110 transmits information on which the drive motor 120 is driven, so that the rotation information on which the drive motor 120 is rotated can be produced. Here, the production can be based on a predetermined rule as a process of interpreting the information contained in the received electric signal (1), and the predetermined rule is the same as the description described with respect to the information included in the electric signal (1) .

When the rotation information for rotating the driving motor 120 is produced by the drive 110, the rotation information is transmitted to the driving motor 120, and the driving motor can be driven corresponding to the predetermined rotation information. At this time, the power for rotating the motor can be separately supplied from the outside by the power line 50. For example, the voltage for sending the electric signal 1 may be 5V, and the voltage for driving the driving motor 120 may be 12V. The power supply line 50 may be connected to the driving unit 100 to transmit power. That is, the power may be transmitted to the drive 110 or the drive motor 120.

The transmitted power may rotate the drive motor 120 and rotate one side of the idler 200 connected to the axis of the drive motor 120. One side of the eye stray 200 is connected to the driving motor 120 and rotated together with the front section according to the rotation of the driving motor and the other side section is caught by a stopper (not shown) . Since the predetermined interval excluding the entire interval is driven to rotate only one side of the eye strainer 200, the eye strainer 200 can be twisted. The ice stray 200, which is accommodated in the ice-making water and is disposed at a freezing temperature, is twisted to freeze the ice when the ice-making water changes to ice (ice-making).

The driving motor 120 may be driven to twist the icestra 200 and the driving motor 120 may drive the driving motor 120 to rotate the electric signal 1, The rotation information can be generated and transmitted by the drive 110 based on the rotation information. That is, in this embodiment, the electric signal 1 to be the rotation information is determined by the selective transmission of the cross output unit 300, and the ice making can be performed.

3, the electric signal 1 transmitted from the signal transmitting unit 500 (MICOM) transmits and receives an electric signal 1 with a signal converter, converts the electric signal 1 into rotational information, ). The driving motor 120 can be rotated so as to correspond to the transmitted rotation information (converted electric signal).

4 and 5 are views for explaining the operation of the icemaker 10 according to the third embodiment of the present invention.

4 and 5, the icemaker 10 may include a signal transmitting unit 500a, a signal receiving unit 400a, a driving unit 100a, and an eye strainer 200a for transmitting an electric signal 2.

Specifically, the signal transmitting unit 500a may transmit the electric signal 2 so that the driving unit 100a may be driven according to the information included in the electric signal 2. [ The electric signal 2 received from the signal transmitting unit 500a may be transmitted to the signal receiving unit 400a. The direction of transmission may determine the operation information of the driving unit to which the electric signal 2 is finally transmitted to the electric signal.

Furthermore. The information contained in the electrical signal 2 is transmitted in a different pps (pulse per secomd) when the electrical signal 2 is delivered in the form of a pulse so that each pps (pulse per secomd) may contain specific information . For example, when the signal is transmitted at 180 pps, when the signal is transmitted at 500 pps in forward rotation, the driving unit may be driven in the reverse direction. As described above, not only the information related to the rotation direction but also information including the rotation angle and the torque. In the case of a digital signal of 0, 1, -1, etc., the rotation direction, the rotation angle, the torque, and the like can be determined as a result of signal combination transmitted for each of a plurality of signal lines.

The electric signal 2 may be received by the signal receiving unit 400a and transmitted to the driving unit 100a. The driving unit 100a may be driven by receiving the electric signal. The driving unit 100a may include a driving unit 110a and a driving motor 120a. The drive 110a can generate rotation information by which the drive motor 120a is rotated by transmitting information on which the drive motor 120a is driven. Here, the production can be based on a predetermined rule as a process of interpreting the information contained in the received electric signal (2), and the predetermined rule is the same as the description described with respect to the information included in the electric signal (2) .

When the rotation information for rotating the driving motor 120a is produced in the drive 110a, the rotation information is transmitted to the driving motor 120a, and the driving motor can be driven corresponding to the predetermined rotation information. At this time, the power for rotating the motor may be separately supplied from the outside by the power line 50a. For example, the voltage for sending the electric signal 2 may be 5V, and the voltage for driving the drive motor 120a may be 12V. The power line 50a may be connected to the driving unit 100a to transmit power. That is, the power may be transmitted to the drive 110 or the drive motor 120.

The transmitted power may rotate the drive motor 120a and rotate one side of the eye strainer 200a connected to the axis of the drive motor 120a. One side of the eye stray 200a is connected to the driving motor 120a and is rotated together with the front section according to the rotation of the driving motor, and the other side section is caught by a stopper (not shown) . Since the predetermined interval excluding the entire interval is driven to rotate only one side of the eye strainer 200a, the eye straighter 200a can be twisted. The icemaker 200a, which accommodates the ice-making water and is disposed at a subzero temperature, is twisted to ice the icemaker 200a in order to freeze the ice-making water when the ice-making water changes to ice.

The driving motor 120a can be driven to twist the icestra 200a and the driving motor 120a can drive the electric signal 2 to twist the icestra 200a, And can be produced and transmitted as rotation information by the drive 110a.

In the case of digital signals of 0, 1, -1, etc., the rotation speed, the rotation direction, the rotation angle, the torque, and the like can be determined as a result of signal combination transmitted for each of a plurality of signal lines. That is, the electrical signal may be in bipolar form. Of course, it can be a unipolar type. For example, even in the case of a digital signal which is a signal of 1, 0, the rotational speed, the rotational direction, the rotational angle and the torque can be determined through the combination of the respective signals. That is, the electric signal may be applied to one or more of bipolar and unipolar.

As shown in FIG. 5, the 12V DC electric power may be power for driving the driving motor 120 driven according to the electric signal 1 transmitted from the signal transmitting unit 500 (MICOM). This means that the driving motor 120 is driven by receiving a power other than the signal transmission power, but the present invention is not limited thereto. Also, when separate power is supplied, a voltage of 12 volts DC may be supplied.

6 and 7 are views for explaining the operation of the ice maker according to the fourth embodiment of the present invention.

6 and 7, the icemaker 10 may include a signal transmitting unit 500b, a signal receiving unit 400b, a driving motor 120b, and an eye strap 200b for transmitting a rotation signal 3.

Specifically, the signal transmitting unit 500b may transmit the rotation signal 3 so that the driving motor 120b may be rotated according to the rotation signal 3. The rotation signal 3 received by the signal receiving unit 400b from the signal transmitting unit 500b can finally determine the operation information of the driving unit to which the electric signal 1 is transmitted.

Furthermore. The information contained in the rotation signal 3 is transmitted in a different pps (pulse per secomd) when the rotation signal 3 is transmitted in a pulse form so that each pps (pulse per secomd) may contain specific information . For example, when the rotation speed is 180 pps, when the rotation speed is 500 pps, the driving motor 120b may be driven in the reverse direction. As described above, not only the information related to the rotation direction but also information including the rotation angle and the torque.

In the case of digital signals of 0, 1, -1, etc., the rotation speed, the rotation direction, the rotation angle, the torque, and the like can be determined as a result of signal combination transmitted for each of a plurality of signal lines. That is, the electrical signal may be in bipolar form. Of course, it can be a unipolar type. For example, even in the case of a digital signal which is a signal of 1, 0, the rotational speed, the rotational direction, the rotational angle and the torque can be determined through the combination of the respective signals. That is, the electric signal may be applied to one or more of bipolar and unipolar.

The electric signal 1 transmitted from the signal transmitting unit 500b can be received by the signal receiving unit 400b and transmitted to the driving unit 120b. The driving motor 120b may be driven by receiving the electric signal. The signal receiving unit 400b can transmit rotation information that the driving motor 120 is rotated by transmitting information on which the driving motor 120 is driven. That is, the driving motor 120b can be driven according to a digital or pulse signal without separately processing or interpreting the received information. That is, it corresponds to the contents described in the information included in the electric signal 1 described above.

When the rotation information 3 for rotating the driving motor 120b is received, the driving motor 120b can be driven corresponding to the predetermined rotation information 3. At this time, the power for rotating the driving motor 120b may be supplied separately from the outside by the power line 50b. For example, the voltage for sending the rotation signal 3 may be 5V, and the voltage for driving the drive motor 120b may be 12V. The power line 50b may be connected to the driving motor 120b to transmit power. That is, the power may be transmitted to the driving motor 120.

The transmitted power may rotate the driving motor 120b and rotate one side of the eye straighter 200b connected to the axis of the driving motor 120b. One side of the eye stray 200 is connected to the driving motor 120b and is rotated together with the front section according to the rotation of the driving motor and the other side section is caught by a stopper (not shown) . Since the predetermined interval excluding the entire interval is driven to rotate only one side of the eye straighter 200b, the eye straighter 200b can be twisted. The ice stray 200b, which receives the iced water and is disposed at a subzero temperature, is twisted to ice the iced ice in order to freeze the iced water when the iced water is changed into ice.

In this case, the driving motor 120b may be driven to twist the icemaster 200, and the driving motor 120 may rotate the rotation information 3, Can be produced and delivered. That is, in the present embodiment, the rotation signal 3 transmitted from the signal transmission unit 500b is transmitted to the drive motor 120b through the signal reception unit 400b, and can perform ice-making.

As shown in FIG. 7, the 12V DC electricity may be power for driving the driving motor 120 driven according to the electric signal 1 transmitted from the signal transmitting unit 500 (MICOM). This means that the driving motor 120 is driven by receiving a power other than the signal transmission power, but the present invention is not limited thereto. Also, when separate power is supplied, a voltage of 12 volts DC may be supplied.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the present invention. I will understand. Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by equivalents to the appended claims, as well as the appended claims.
