Description

Ice maker module and refrigerator {ICE MAKER MODULE AND REFRIGERATOR INCLUDING THE SAME}

The present invention relates to an ice making module and a refrigerator including the same.

In general, a refrigerator includes a main body including a refrigerating chamber for refrigerating and storing food and a freezing chamber for freezing and storing food, and a compressor for compressing a refrigerant and a heat exchanger for generating cold air are installed behind the main body. The cold air generated from the heat exchanger is supplied to the inside of the refrigerator or freezer by a fan, and the air whose temperature has risen by circulating the refrigerator or freezer is supplied to the refrigerator or freezer through the heat exchanger. You can always keep it fresh. In this case, an ice maker for manufacturing ice is installed in the freezing chamber or the refrigerating chamber.

The ice maker automatically supplies water to the ice making container and checks the ice making condition. When the ice making is complete, the ice is automatically removed from the ice making container and loaded into the ice storage container. Can be obtained and has been widely used recently.

The ice maker is supplied with water to the ice making container and in order to ice the ice made, various sensors (eg, ice-making water sensor, position sensor, ice detection sensor, temperature sensor, etc.) and motors (eg, ejector motor or twist Motor, etc.). The second controller, which controls the overall operation of the ice maker, receives a sensing signal from such a sensor, transmits the received sensing signal to the first controller provided in the refrigerator body, and receives a motor control signal from the first controller to receive a motor in the ice maker. They control their behavior. In this process, a large number of wires may increase the volume of the ice maker. Accordingly, a reduction in a large number of wirings in the refrigerator or a change in the arrangement structure of the ice maker is required.

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

In describing the present invention, when it is determined that a detailed description of known technologies related to the present invention may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted. In addition, terms to be described later are terms defined in consideration of functions in the present invention and may vary according to the intention or custom of users or operators. Therefore, the definition should be made based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are only one means for efficiently describing the technical idea of the present invention to those of ordinary skill in the art.

In the ice making module of the present invention, which will be described below, wiring for communication with the refrigerator can be simplified because a control box including a first control box and a second control box is disposed on the door of the refrigerator, and the first It includes a feature that can also control the control unit provided in the second control box by the second control unit included in the control box.

In the communication, as shown in FIG. 6, the signal transmitted to the second controller 150 of the ice making module 100 is a motor drive 230 or a switched mode power supply (SMPS) 250. It can be delivered via.

And, as described above, the second control unit 150 may be provided in the control box 110. In the following embodiment to implement the present invention, the second control unit 150 is located in the first control box 111 Let's explain the example.

In addition, the second control box 112 and the first control box 111 are disposed on the door side, but may be spaced apart from each other. Since the first control box 111 connected to the ice making tray 140 is located above the second control box 112 connected to the storage unit 130, the ice made can be moved into the storage unit 130 by its own weight. Can be arranged so that An ice discharge unit (not shown) may be provided on the door side to allow ice to be extracted from the storage unit 130 to which the ice has been moved.

Accordingly, in order for ice to be drawn out of the refrigerator, the ice discharging unit and the storage unit may communicate with a space in which ice can be moved, and an opening is formed in the case even when the case is further provided, so that the communication can be maintained. It will be described later in more detail with reference to FIGS. 1 to 5 below.

1 is a view showing a refrigerator 10 including an ice making module 100 according to an embodiment of the present invention.

Referring to FIG. 1, the refrigerator 10 may include an ice making module 100 and a first control unit 1. The ice making module 100 may control some operations of at least some components according to a control signal from the first controller 1 provided in the refrigerator 10, and may be located on the door 11 side of the refrigerator 10. .

In this embodiment, a plurality of cabinets may be provided vertically. Each of the cabinets 12 and 13 at this time may have a different temperature environment created in the internal space. Accordingly, the first cabinet 12 positioned at the upper side and the second cabinet 13 positioned at the lower side may be provided to be thermally partitioned by the partition wall 14. For example, the first cabinet 12 may maintain a sub-zero temperature, and the second cabinet 14 may maintain the temperature of an image.

Accordingly, the ice making module 100 according to an embodiment of the present invention may be located in a space maintaining a sub-zero temperature, that is, in an environment where the first cabinet 12 is exposed to the temperature or at the same temperature. Ice made by the ice making module 100 located in the first cabinet 12 may be provided to the user through a dispenser (not shown) formed on the door 11 side.

Meanwhile, in the ice making module 100 according to an embodiment of the present invention, the control box 110 may be located on the door 11 side. Since the dispenser is generally formed outside the door 11 of the refrigerator 10, It may be located above the door 11.

Meanwhile, a wiring arranged to receive a signal from the first control unit 1 may extend toward the ice making module 100, and the extension path is provided for coupling the door 11 to the refrigerator 10, for example. The wiring may be formed through a hinge or a portion coupled to the hinge, and the wiring may connect the first control unit 1 and the ice making module 100.

2 is a diagram illustrating a connection between the first control unit 1 and the second control unit 150 according to an embodiment of the present invention.

Referring to FIG. 2, the first control unit 1 provided on the refrigerator 10 side may be a main control unit. In other words, the refrigerator 10 may be provided with other independent components in addition to the ice making module 100 shown in FIG. 1, and may be connected to and controlled by the above components. The configurations further include a separate control unit, so that the first control unit 1 does not directly control it, but can indirectly control it through the separate control unit. Through this, control is possible even if the first control unit 1 and a driving unit included in an individual configuration are not directly connected.

In the case of the ice-making module 100, the second control unit 150 of the ice-making module 100 is connected to the first control unit 1 of the refrigerator 10, and the second control unit 150 is the motor unit 170 , It is also possible to directly control sub-components included in the ice making module 100 such as the ice making tray 140, auger motor 160, auger screw 161, and the like. For example, from the first control unit 1, only a signal indicating whether the second control unit 150 is operating may be transmitted, and the second control unit 150 may transmit specific operation information to each component for control. For example, the first control unit 1 may transmit a signal to rotate the motor unit 170, and the second control unit 150 may control the motor unit 170 to rotate at a predetermined angle and speed. .

Meanwhile, the control box 110 may include a first control box 111 and a second control box 112. Here, the first control box 111 and the second control box 112 may be physically separated from each other, or may mean functionally divided configurations. The functionally divided configuration means that the first control box 111 controls a driving unit that includes a function to perform ice ice, and controls the configuration in which the second control box 112 stores and discharges ice ice. Means to do. That is, when the first control box 111 is an ice making module including a heater ice maker, a heater, a water supply unit, an ejector, and a motor that rotates the ejector may control the first control box 111. Of course, in the case of the twist ice maker, the ejector and the motor that rotates the ejector may be replaced with a motor that rotates the ice tray 140 to function.

The second control box 112 controls the auger screw 161 and the auger motor 160 that rotates the auger screw 161 and rotates for discharging or crushing to the user when the ice cubed ice is stored in the storage unit 130 Means the ability to do.

Each component may be connected to the second control unit 150 in order to receive an operation signal by the second control unit 150 that has received a signal from the first control unit 1 in order to operate the series of operations described above. The connection with the second control unit 150 may be an electrical connection through wiring. In this embodiment, an electrical connection between the second control unit 150 and the driving unit is possible within the control box 110, so that the control box Separate wiring for connection between (111, 112) may not be required.

On the other hand, even when the first control box 111 and the second control box 112 are arranged due to the classification of the physical control box 110 described above, it is significantly more pronounced than when the second control unit 150 is horizontally spaced apart. It can be simplified. The simplification of the wiring is that the case 101 in which the wiring is to be provided can be downsized by the size of the simplified wiring, and the downsizing is possible, so that the internal volume of the first cabinet 12 can be increased. This increase in internal volume may be an effect that can be expected without increasing the size of the refrigerator 10 or changing the internal design.

3 is a view showing a driving unit operated by the second control unit 150 according to an embodiment of the present invention.

Referring to FIG. 3, the second control unit 150 receives a first signal S1 transmitted from the first control unit 1 provided in the refrigerator 10, and the second control unit 150 receives a second signal S2. It is possible to control the driving units 170, 180, and 190 by transmitting to the driving units 170, 180, 190. Here, the driving unit 170, 180, 190 includes a first operation unit 180 and a second operation unit 190, and the first operation unit 180 is a component that operates on the first control box 111 side. , The second operation unit 190 may be classified into a configuration that operates on the side of the second control box 112.

Alternatively, one of the first operation unit 180 and the second operation unit 190 may be a configuration requiring feedback, that is, an operation unit that is required to transmit whether or not the detection unit is detected to the first control unit 1 again. . The other one may be an operation unit in which the operation of the configuration ends in receiving a heating signal and performing heat generation, such as heating. This classification is because it may be required to divide the wiring for communication, which can be described in detail with reference to FIGS. 4 and 5 below.

4 is a diagram illustrating a driving and communication flow of an ice maker according to the first embodiment of the present invention.

Referring to FIG. 4, the refrigerator 10 and the second controller 150 may communicate through a communication bus 210. When the communication bus 210 transmits and receives via a connection between a universal asynchronous receiver/transmitter (UART) unit and a port, it transmits an operation signal from the refrigerator 10 to the second control unit 150, and , The refrigerator 10 may receive sensing information from the second control unit 150. The operation signal may include an operation signal for driving a driving motor including the motor unit 170 and the Auger motor 180. Here, the motor unit 170 may be a motor for rotating the ejector, but in the case of a twister ice maker other than a heater type, it may be a motor that twists for eaves. The Auger motor 180 may be rotated in a process of transferring or crushing ice stored in the storage unit 130 to be discharged.

Since the respective information for driving the motor unit 170 and the Auger motor 180 may be different from each other, individual information may be transmitted from each other. The information may include information such as rotation speed, rotation angle, and rotation torque of the motor, respectively. This is because the torque is prioritized when the ice is crushed or twisted to freeze the frozen ice in the ice making tray 140, and the rotational speed is prioritized when the ejector is rotated, so the information included in the operation signal may be different.

In addition, the operation signal may include driving information of the heater D5. Here, the heater (D5) may be a heater (D5) that defrosts the outlet to prevent ice from forming at the outlet while the fluid formed by condensation, etc., located on the side of the ice bank where the Auger motor 180 is located is discharged. have. The heating information of the heater D5 may be determined within a predetermined time period, for example, within a predetermined temperature section. Of course, when the heat exceeds a predetermined temperature range, heat generation of the heater D5 may be blocked by an overheating preventing means (not shown).

For example, when a sensor detecting the temperature of the heater D5 transmits the heat detection information of the heater D5 to the refrigerator 10 through the second controller 150, the first controller 1 An operation signal including "stop" information may be transmitted to the second control unit 150. The second control unit 150 may identify and transmit the location where the “heating stop” information is to be transmitted, that is, the heater D5.

As various examples, the ice making module 100 may include a temperature sensor D1, a water level detection sensor D2, a full ice detection sensor D3, a position sensor D4, and the like. As described above, each sensor When the sensed sensing information is transmitted to the second controller 150, the second controller 150 may transmit the sensing information to the refrigerator 10 to receive feedback information corresponding to each sensing information from the refrigerator. The feedback information received back may be transmitted to various locations, and it may be distinguished and transmitted to correspond to the temperature sensor D1, the water level detection sensor D2, the ice detection sensor D3, and the position sensor D4.

In the above-described communication method, communication between the second control unit 150 and the refrigerator 10 may be communication through transmission and reception through a connection between a universal asynchronous receiver/transmitter (UART) unit and a port, as described above. have. Universal Asynchronous Receiver/Transmitter (UART) includes various communication methods, for example, K-LINE communication, RS232, RS422, RS485, and LIN (Local Interconnect Network) communication.

Here, K-line communication is a diagnostic protocol that complies with the ISO 14230 standard, and is based on a typical UART (Universal Asynchronous Receiver Transmitter) circuit technology like a standard RS232 serial interface. In the case of universal asynchronous transmission and reception, the sender and receiver use the start bit and stop bit for synchronization purposes. This means that a single line is sufficient for the system without additional lines. In contrast to the RS232, K-Line communication can communicate with various ECUs like a bus system. The standard baud rate is 10,400 baud and the maximum rate is 115.2 K baud, which can be used for flash memory programming and other purposes.

In addition, K-Line is suitable for both onboard and offboard diagnostics and can provide two kinds of special initialization patterns. In addition, one of the characteristics of K-Line may be a special key byte used when checking a header format and timing parameters.

The communication module may convert each sensing signal received from the second control unit 150 into data suitable for corresponding network communication, and then transmit it to the refrigerator 10 through the communication bus 210. That is, when the corresponding network communication is LIN communication, the communication module may convert each sensing signal received from the second control unit 150 into data according to the LIN protocol, and then transmit the data to the refrigerator through the communication bus 210.

Accordingly, wiring for communication between the ice making module 100 and the refrigerator 10 can be minimized, so that the ice making module 100 can be miniaturized, and generation of noise and electromagnetic waves can be reduced.

5 is a diagram illustrating a driving and communication flow of an ice maker according to a third embodiment of the present invention.

Referring to FIG. 5, the refrigerator 10 including the first controller 1 and the ice maker 100a may communicate through a communication bus 210. When the communication bus 210 communicates with a universal asynchronous receiver/transmitter (UART) unit, it transmits an operation signal from the first control unit 1 to the ice maker 100a and detects it from the ice maker 100a. The first control unit 1 may receive information. The operation signal may include an operation signal for driving a driving motor including the motor unit 170 and the Auger motor 180. Here, the motor unit 170 may be a motor for rotating the ejector, but in the case of a twister ice maker other than a heater type, it may be a motor that twists for eaves. In addition, the Auger motor 180 may be an Auger motor. The ice stored in the storage unit 130 may be an auger motor that is rotated in the process of transporting it to be discharged.

Since the respective information for driving the motor unit 170 and the Auger motor 180 may be different from each other, individual information may be transmitted from each other. The information may include information such as rotation speed, rotation angle, and rotation torque of the motor, respectively. This is because the torque is prioritized when the ice is crushed or twisted to freeze the frozen ice in the ice making tray 140, and the rotational speed is prioritized when the ejector is rotated, so the information included in the operation signal may be different.

In addition, the operation signal may include driving information of the heater D5. Here, the heater D5 may be a heater D5 that defrosts the outlet to prevent ice from forming at the outlet through which a fluid formed by condensation, etc., located on the side of the ice bank where the Auger motor 180 is located is discharged. . The heating information of the heater D5 may be determined within a predetermined time period, for example, within a predetermined temperature section. Of course, when the heat exceeds a predetermined temperature range, heat generation of the heater D5 may be blocked by an overheating preventing means (not shown).

For example, when a sensor that senses the temperature of the heater D5 transmits heat detection information of the heater D5 to the first control unit 1 through the ice maker 100a, the first control unit 1 An operation signal including "stop" information may be transmitted to the ice maker 100a. The ice maker 100a may stop heating the heater by receiving the "heating stop" information.

As various examples, the ice maker 100a may include a temperature sensor D1, a water level detection sensor D2, a full ice detection sensor D3, and a position sensor D4, and each sensor detects it as described above. When one sensing information is transmitted to the first controller 1, feedback information corresponding to each sensing information of the first controller 1 may be transmitted to the ice maker 100a. The received feedback information may be transmitted to correspond to the temperature sensor D1, the water level detection sensor D2, the ice detection sensor D3, and the position sensor D4.

In the above-described communication method, communication between the second control unit 150 and the first control unit 1 may be communication transmitted and received with a universal asynchronous receiver/transmitter (UART) unit, as described above. Universal Asynchronous Receiver/Transmitter (UART) includes various communication methods, for example, K-LINE communication, RS232, RS422, RS485, and LIN (Local Interconnect Network) communication.

After the first control unit 1 converts each sensing signal into data suitable for a corresponding network communication, the communication module may transmit the data to the ice maker 100a through the communication bus 210. That is, when the network communication is LIN communication, the communication module converts each sensing signal received from the first control unit 1 according to the LIN protocol, and then transmits the data to the ice maker 100a through the communication bus 210. have.

Accordingly, wiring for communication between the ice making module 100 and the refrigerator 10 can be minimized, so that the ice making module 100 can be miniaturized, and generation of noise and electromagnetic waves can be reduced.

Furthermore, in the case of including a CAN port, the communication network of the refrigerator 10 may be a controller area network (CAN), and the communication bus 210 may be formed of two twisted pair wires. One of the two twisted wires may transmit a CAN HIGH signal, and the other may transmit a CAN LOW signal. Here, by using different voltages for the two twisted wires, electrical noise can be reduced.

In addition, when the communication network of the refrigerator 10 is a controller area network (CAN), each electronic control device may be assigned a unique identifier. The unique identifier may consist of 11 bits or 29 bits. Here, priority for data transmission may be set between each electronic control device through a bit value of the unique identifier. That is, when a plurality of electronic control devices simultaneously transmit data through the communication bus 210, data of the electronic control device having a high priority according to the bit value of the unique identifier is prioritized and transmitted.

Meanwhile, when the communication network of the refrigerator 10 is a local interconnect network (LIN), the communication bus 210 may be formed of one line. In addition, when the communication network of the refrigerator 10 is a local interconnect network (LIN), the first control unit 1 becomes a master node, and the second control unit 150 and the driving unit D become slave nodes to perform communication. can do. Here, the first controller 1 as a master may switch an operation mode from an active mode to a sleep mode according to a state of use of the communication bus 210. For example, when there is no data transmission through the communication bus 210 for a preset time, some of the driving units D may switch the communication network mode to the sleep mode to prevent unnecessary power waste.

In this way, when a controller area network (CAN) or a local interconnect network (LIN) is used as the communication network of the refrigerator 10, when another driving unit D, which is not illustrated, is added to the refrigerator 10, the driving unit D ) To the communication bus 210, it is possible to secure excellent expandability according to specification changes.

Although the exemplary embodiments of the present invention have been described in detail above, those of ordinary skill in the art to which the present invention pertains will understand that various modifications may be made to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention should not be defined by being limited to the described embodiments, and should not be determined by the claims to be described later, but also by the claims and equivalents.
