Description

Technical Field

[0001] This application relates to home appliance technology, including but not limited to a refrigerator. Background Technology

[0002] Existing refrigerators have different types of storage compartments and functions. Moreover, with the development of technology, refrigerators have more and more added value-added functions, resulting in a wide variety of refrigerator control boards and connecting wires, which is not conducive to production material management and cost reduction. Utility Model Content

[0003] In view of this, the refrigerator provided in this application embodiment can reduce the types of connecting wires on the main control board and reduce the types of materials, which is conducive to improving production efficiency.

[0004] This application provides a refrigerator, including:

[0005] A housing having at least one storage compartment, the storage compartment including at least a refrigerator compartment and / or a freezer compartment;

[0006] The compressor is located inside the housing;

[0007] A refrigeration system for providing cooling capacity to the refrigerator, the refrigeration system comprising a compressor, a condenser and an evaporator connected in sequence by pipes;

[0008] The main control board includes:

[0009] The first control module is electrically connected to the refrigeration load of the refrigerator via a first wiring harness, and is used to control the operation of the refrigeration load. The refrigeration load includes one or more of the following: the refrigerator's display panel, compressor, defrost heater, lighting in the storage compartment, and temperature sensor in the storage compartment.

[0010] The second control module is electrically connected to the additional load of the refrigerator via a second wiring harness, and is used to control the operation of the additional load, which includes other loads in the refrigerator besides the refrigeration load.

[0011] In the aforementioned refrigerator, by setting a first control module and a second control module in the main control board, the first control module is electrically connected to the refrigeration load through a first wiring harness, and the second control module is electrically connected to the additional load in the refrigerator other than the refrigeration load through a second wiring harness. Thus, the first control module controls the operation of the refrigeration load, and the second control module controls the operation of the additional load. The connection harnesses on the main control board can be distinguished according to the load type, thereby modularizing the design of the connection harnesses. This facilitates the reduction of the number of connection harnesses, improves the efficiency of production material management, reduces the types of materials, and is conducive to improving production efficiency.

[0012] In some embodiments, the first control module is electrically connected to the second control module, wherein:

[0013] The first control module is used to send control signals to the second control module;

[0014] The second control module is used to receive and respond to the control signal to control the operation of the additional load.

[0015] It is understandable that by electrically connecting the first control module and the second control module, the second control module can be triggered by the first control module to control the additional load. This facilitates centralized management of the control process of the additional load and the control process of the cooling load by the first control module, thereby improving control efficiency.

[0016] In some embodiments, the refrigerator further includes a drive circuit disposed between the additional load and the second control module, for driving the additional load to work under the control of the second control module.

[0017] Understandably, when an additional load requires a drive circuit, setting up a drive circuit between the additional load and the second control module can achieve precise control of the additional load and ensure that the additional load can work normally.

[0018] In some embodiments, the second wiring harness includes a power line, a communication line, and a ground line. The power line and the ground line are used to supply power to the drive circuit through the second control module, and the communication line is used to enable communication between the second control module and the additional load.

[0019] Understandably, by setting up a second harness that includes power lines, communication lines, and ground lines, the harness can be integrated, reducing the number of different types of harnesses.

[0020] In some embodiments, the number of additional loads is at least two, the drive circuit includes at least two drive modules, the second control module is electrically connected to the at least two drive modules respectively, and different drive modules are connected to different additional loads.

[0021] It is understandable that by using different drive modules to drive different additional loads, the second control module can drive multiple additional loads simultaneously, reduce mutual interference between different additional loads during driving, and improve operating efficiency.

[0022] In some embodiments, the second control module communicates with the at least two drive modules via a bus communication method, and the different drive modules have different communication addresses.

[0023] It is understandable that using bus communication to enable the second control module to drive at least two drive modules can reduce the number of communication lines between the second control module and the at least two drive modules, thereby reducing costs.

[0024] In some embodiments, the additional load includes one or more of the following: a fan disposed in the storage compartment, a damper disposed in the storage compartment, and a fan disposed at the bottom of the housing.

[0025] It is understandable that the operation of the fans, dampers, and bottom fans in the storage compartments can guide the cold air to circulate separately in each storage compartment, further enhancing the cooling effect in each compartment. This additional cooling effect is an extra function on top of the basic cooling function and is not required by all refrigerator products. Therefore, connecting the fans, dampers, and bottom fans in the storage compartments through a second wiring harness can reduce the problem of having a large number of wiring harnesses due to the excessive load functions in different storage compartments of the refrigerator.

[0026] In some embodiments, a terminal block is provided in the target area, one end of the terminal block is electrically connected to the additional load, and the other end of the terminal block is connected to the second wire harness. The target area is the space within the refrigerator that is within a preset distance threshold from the additional load.

[0027] It is understandable that setting up terminal blocks in the target area can enable quick connection between the second control module and the additional load. Furthermore, as the number of additional loads increases, the additional loads in the refrigerator can be expanded by directly connecting them to the terminal blocks, thus reducing wiring time.

[0028] In some embodiments, the main control board further includes a power supply module, the input terminal of which is connected to the mains power connection terminal, and the output terminal of which is connected to the first control module and the second control module respectively, for supplying power to the first control module and the second control module.

[0029] It is understandable that by setting up a power supply module in the main control board, and thus powering the first and second control modules, power supply components can be saved, costs can be reduced, wiring space can be saved, and power supply reliability can be improved.

[0030] In some embodiments, the power supply module is also electrically connected to the cooling load and the additional load. The power supply module includes multiple voltage conversion units with different output power. The first control module controls a target voltage conversion unit to supply power to the cooling load and the additional load based on the power of the cooling load and the additional load. The target voltage conversion unit is one of the multiple voltage conversion units.

[0031] It is understandable that by setting multiple voltage conversion units in the power supply module, the first control module can control the target voltage conversion unit to supply power to the cooling load and additional load according to the power requirements of different cooling loads and additional loads, thereby achieving targeted power supply for different loads and realizing the power supply compatibility of the power supply module.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0042] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0043] It should be noted that the terms "first, second, third" used in the embodiments of this application are used to distinguish similar or different objects and do not represent a specific order of objects. It can be understood that "first, second, third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0044] Figure 1 This is a structural schematic diagram of a refrigerator provided in an embodiment of this application. The refrigerator in this embodiment may include a cabinet 100. The cabinet 100 has at least one compartment. Specifically, as shown... Figure 2 As shown, the refrigerator in this embodiment has an approximately rectangular shape. The refrigerator includes a cabinet 100 that defines a storage space. The cabinet 100 has at least one compartment 101, and each compartment 101 has one or more doors 102 at its opening.

[0045] In some embodiments, the upper compartment 101 can be a refrigerator compartment, which has a double door. The door 102 includes a door shell located outside the cabinet 100, a door inner liner located inside the cabinet, an upper end cover 230, a lower end cover, and an insulation layer located between the door shell, the door inner liner, the upper end cover, and the lower end cover; typically, the insulation layer is filled with foam material. The compartment 101 can be configured as a refrigerator compartment, a freezer compartment, a variable temperature compartment, etc., depending on its purpose. The refrigerator also includes a refrigeration system for cooling the compartments within the cabinet 100.

[0046] Figure 3 This application provides a schematic diagram of a refrigeration system, applied to the aforementioned refrigerator. The refrigeration system may include a compressor 1, an evaporator 2, a condenser 3, and a defrost heater 4, as shown below. Figure 3 As shown, after the compressor 1 discharges the refrigerant, the refrigerant first enters the condenser 3, then enters the evaporator 2, and finally flows back to the compressor 1, completing the refrigeration cycle.

[0047] In some embodiments, the main control board may include a controller, thereby controlling the loads in the refrigerator to operate. The loads in the refrigerator may include a display panel, a sensor for detecting whether the door of the storage compartment is open, lighting in each storage compartment, temperature sensors in each storage compartment, defrosting heater 4, compressor 1, and dampers and fans in each storage compartment.

[0048] However, as technology advances, refrigerators are adding more and more value-added functions, resulting in an increasing number of loads on the refrigerator. Different loads have different effects on the refrigerator's cooling performance. If all loads are still controlled by a single control module, the number of wiring harnesses on the main control board will be too large, which is not conducive to production material management and cost reduction.

[0049] In view of the above problems, this application provides a main control board 20 applied to a refrigerator. By setting a first control module 201 and a second control module 202 in the main control board 20, the first control module 201 is electrically connected to the refrigeration load 30 through a first wiring harness, and the second control module 202 is electrically connected to an additional load 40 in the refrigerator other than the refrigeration load 30 through a second wiring harness. Thus, the first control module 201 controls the operation of the refrigeration load 30, and the second control module 202 controls the operation of the additional load 40. The connecting wiring harnesses on the main control board can be distinguished according to the load type, thereby modularizing the design of the connecting wiring harnesses, which facilitates the reduction of the number of connecting wiring harnesses, improves the efficiency of production material management, reduces the types of materials, and is conducive to improving production efficiency.

[0050] In some embodiments, such as Figure 4 As shown, the main control board 20 may include a first control module 201 and a second control module 202. The first control module 201 is electrically connected to the refrigeration load 30 of the refrigerator through a first wiring harness, and the second control module 202 is electrically connected to the additional load 40 of the refrigerator through a second wiring harness.

[0051] The first control module 201 is used to control the operation of the refrigeration load 30, which includes one or more of the following: the refrigerator's display panel, compressor 1, defrost heater 4, lighting in the storage compartment, and temperature sensor in the storage compartment.

[0052] The second control module 202 is used to control the operation of the additional load 40, which includes other loads in the refrigerator besides the refrigeration load 30.

[0053] Among them, the cooling load 30 refers to the load that realizes the most basic cooling function of the refrigerator, such as the high-voltage loads such as the compressor and defrost heater 4, as well as a small number of loads such as the lighting in the storage compartment and the sensors in the refrigerator. Usually, the first control module 201 and the cooling load 30 can form the cost-optimal control board for the refrigerator.

[0054] The additional load 40 refers to the other loads in the refrigerator besides the cooling load 30. Usually, manufacturers add other additional functions on the basis of the basic cooling function to enhance the competitiveness of the product. After adding the additional load 40, the refrigerator can further improve the cooling effect on the basis of the basic cooling function achieved by the cooling load 30, and can also achieve additional functions such as sterilization and preservation.

[0055] In some embodiments, the additional load 40 may include one or more of the following: a fan disposed in the storage compartment, a damper disposed in the storage compartment, and a fan disposed in the compressor compartment. The compressor compartment is the space in the refrigerator where the compressor is located. The compressor compartment may be located at the bottom of the refrigerator body or on the side wall of the refrigerator body, as determined by those skilled in the art according to the actual situation. The storage compartment may include a refrigerator compartment, a freezer compartment, and a variable temperature compartment.

[0056] It is understandable that the operation of the fans, dampers, and bottom fans in the storage compartments can guide the cold air to circulate separately in each storage compartment, further enhancing the cooling effect in each compartment. This additional cooling effect is an extra function on top of the basic cooling function and is not required by all refrigerator products. Therefore, connecting the fans, dampers, and bottom fans in the storage compartments through a second wiring harness can reduce the problem of having a large number of wiring harnesses due to the excessive load functions in different storage compartments of the refrigerator.

[0057] In this embodiment, the first control module 201 controls the operation of the refrigeration load 30, and the second control module 202 controls the operation of the auxiliary load 40. The load in the refrigerator is divided into the refrigeration load 30 and the auxiliary load 40. The refrigeration load 30 is the basic functional device for the refrigerator to operate in refrigeration mode, while the auxiliary load 40 is an additional function added by various manufacturers. Since the auxiliary load 40 is different for refrigerators with different functional requirements, technicians can add or remove the number of auxiliary loads 40 according to functional requirements. When the second control module 202 connects the auxiliary load 40 through the second wiring harness, the connection wiring harness of the auxiliary load 40 can be standardized, avoiding the need to add additional wiring harnesses when the auxiliary load 40 is added due to the addition of additional functions of the refrigerator, thereby reducing the types of materials.

[0058] In some embodiments, the first control module 201 can be an integrated processor, the second control module 202 can be an integrated processor, the first control module 201 and / or the second control module 202 can be a microcontroller, a programmable logic gate circuit, etc., and the first control module 201 and the second control module 202 can be the same or different.

[0059] In some embodiments, since the additional load 40 can be removed, there may be a situation in the refrigerator where there is no additional load 40. In this case, the second wiring harness can be omitted from connecting the second control module 202, thereby saving the second wiring harness.

[0060] In some embodiments, such as Figure 5 As shown, the first control module 201 can control the second control module 202, that is, the first control module 201 and the second control module 202 are electrically connected, wherein:

[0061] The first control module 201 is used to send control signals to the second control module 202;

[0062] The second control module 202 is used to receive and respond to control signals to control the operation of the additional load 40.

[0063] In this embodiment, in addition to controlling the cooling load 30 to work, the first control module 201 also sends a control signal to the second control module 202, thereby triggering the second control module 202 to control the additional load 40 to work. The control signal can be an initiation command to instruct the second control module 202 to start controlling the additional load 40 to work, or it can be a control signal that includes control parameters for controlling the additional load 40. After receiving the control signal, the second control module 202 controls the additional load 40 to work according to the control parameters in the control signal.

[0064] It is understandable that by electrically connecting the first control module 201 and the second control module 202, the second control module 202 can be triggered by the first control module 201 to control the additional load 40, which facilitates centralized management of the control process of the additional load 40 and the control process of the cooling load 30 by the first control module 201, thereby improving control efficiency.

[0065] In some embodiments, such as Figure 6 As shown, the refrigerator may also include a drive circuit 50, which is disposed between the auxiliary load 40 and the second control module 202, and is used to drive the auxiliary load 40 to work under the control of the second control module 202.

[0066] Since the additional load 40 needs to be driven by the drive circuit 50 when it is working, a drive circuit 50 needs to be set between the second control module 202 and the additional load 40 for this additional load 40. Thus, the second control signal can drive the additional load 40 by controlling the drive parameters of the drive circuit 50.

[0067] In some embodiments, the circuit structure of the driving circuit 50 can employ common techniques, such as a bridge driving circuit 50 and integrated driving chips like the L298N.

[0068] The drive circuit 50 can be set on a separate circuit board or integrated on the same circuit board as the additional load 40.

[0069] It is understandable that, in the case where the additional load 40 needs to be driven by the drive circuit 50, setting the drive circuit 50 between the additional load 40 and the second control module 202 can achieve precise control of the additional load 40 and ensure that the additional load 40 can work normally.

[0070] In some embodiments, since the second control module 202 needs to send driving parameters to the drive circuit 50 and can also supply power to the drive circuit 50, the second wiring harness may include a power line, a communication line, and a ground line. The power line and ground line are used to enable the second control module 202 to supply power to the drive circuit 50, and the communication line is used to enable communication between the second control module 202 and the additional load 40.

[0071] It is understandable that by setting up a second wiring harness that includes power lines, communication lines and ground lines, communication control between the second control module 202 and the drive circuit 50 can be achieved, thereby realizing the integration of the wiring harness and reducing the types of connecting wiring harnesses.

[0072] In some embodiments, the number of additional loads 40 can be at least two, the drive circuit 50 can include at least two drive modules, the second control module 202 is electrically connected to at least two drive modules respectively, and different drive modules are connected to different additional loads 40.

[0073] In this embodiment, for cases where there are two or more additional loads 40 in the refrigerator, multiple drive modules can be set up so that different additional loads 40 can be driven by different drive modules.

[0074] For example, the additional load 40 includes a refrigerator compartment fan, a refrigerator compartment damper, a freezer compartment fan, a freezer compartment damper, a compressor compartment damper, and a compressor compartment fan. Then, technicians can add different identifiers to the drive modules of different additional loads 40. For example, the refrigerator compartment fan is numbered as drive 11, the refrigerator compartment damper is numbered as drive 12, etc. When the second control module 202 controls the refrigerator compartment fan, it sends a target drive signal including the number of drive 11 to the drive circuit 50, thereby accurately sending the target drive signal to the drive module corresponding to the refrigerator compartment fan, realizing the drive control of the refrigerator compartment fan.

[0075] It is understandable that by driving different additional loads 40 with different drive modules, the second control module 202 can drive multiple additional loads 40 simultaneously, reduce mutual interference between different additional loads 40 during driving, and improve operating efficiency.

[0076] In some embodiments, the second control module 202 communicates and controls with at least two drive modules via bus communication, and the communication addresses of the different drive modules are different.

[0077] In this embodiment, the second control module 202 communicates with at least two drive modules via a bus communication method. The second control module 202 is the master, and each drive module is a slave, with different addresses for each slave. The master communicates with each load according to a pre-defined sequence based on the load address, sending communication requests, communication addresses, and communication commands. When each drive module receives a communication request, it verifies the communication address. If the address is correct, it receives and executes the communication command sent by the master, and returns the corresponding information after execution. Thus, the master can query each drive module according to a pre-defined procedure. When each drive module needs to communicate with the master, it sends a communication request back to the master. The master decides whether to communicate based on a pre-determined priority order.

[0078] It is understandable that by using bus communication to enable the second control module 202 to drive at least two drive modules, the number of communication lines between the second control module 202 and the at least two drive modules can be reduced, thereby lowering costs.

[0079] In some embodiments, a terminal block is provided in the target area. One end of the terminal block is electrically connected to the additional load 40, and the other end of the terminal block is connected to the second wiring harness. The target area is the space within the refrigerator that is within a preset distance threshold from the additional load 40.

[0080] In this embodiment, a terminal block is provided in the target area, which can be connected to the second wire harness. Then, when it is necessary to connect the second wire harness and the additional load 40, the additional load 40 can be directly connected to the terminal block, thereby reducing the wiring time of connecting the additional load 40 to the second control module 202.

[0081] In some embodiments, the terminal block can be a pluggable terminal block, a fixed screw terminal, or a spring cage type.

[0082] It is understandable that by setting up terminal blocks in the target area, a quick connection can be made between the second control module 202 and the additional load 40. Furthermore, when the number of additional loads 40 increases, the additional loads 40 in the refrigerator can be expanded by directly connecting the additional loads 40 to the terminal blocks, thereby reducing wiring time.

[0083] In some embodiments, such as Figure 7 As shown, the main control board 20 may also include a power supply module 203. The input terminal of the power supply module 203 is connected to the mains power connection terminal, and the output terminal of the power supply module 203 is connected to the first control module 201 and the second control module 202 respectively, for supplying power to the first control module 201 and the second control module 202.

[0084] The AC mains connection terminal refers to the connection interface that safely, reliably, and compliantly introduces 220V / 50Hz or 110V / 60Hz AC mains power into the refrigerator. The AC mains connection terminal can be a connection terminal, or a plug / socket, coupler, terminal block, etc.

[0085] In some embodiments, when the operating voltages of the first control module 201 and the second control module 202 are different, the power supply module 203 can be configured to include a first power supply unit and a second power supply unit. The input terminals of the first power supply unit and the second power supply unit are respectively connected to the mains connection terminal. The output terminal of the first power supply unit is connected to the first control module 201, and the output terminal of the second power supply unit is connected to the second control module 202. The output voltages of the first power supply unit and the second power supply unit are different, thereby realizing the power supply of the first control module 201 and the second control module 202 with different voltage requirements.

[0086] It is understandable that by setting a power supply module 203 in the main control board 20, the first control module 201 and the second control module 202 can be powered by the power supply module 203, which can save power supply components, reduce costs, save wiring space, and improve power supply reliability.

[0087] In some embodiments, the power supply module 203 is also electrically connected to the cooling load 30 and the auxiliary load 40. The power supply module 203 includes multiple voltage conversion units with different output power. The first control module 201 controls the target voltage conversion unit to supply power to the cooling load 30 and the auxiliary load 40 according to the total power of the cooling load 30 and the auxiliary load 40. The target voltage conversion unit is one of the multiple voltage conversion units.

[0088] In this embodiment, the power supply module 203 can be equipped with multiple voltage conversion units. Different voltage conversion units have different output power. Therefore, the first control module 201 can control the target voltage conversion unit to supply power to the cooling load 30 and the additional load 40 according to the total power of the cooling load 30 and the additional load 40. The greater the total power, the greater the output power of the target voltage conversion unit.

[0089] For example, the multiple voltage conversion units include a first voltage conversion unit with low output power, a second voltage conversion unit with medium output power, and a third voltage conversion unit with high output power. If there is only a cooling load 30 in the refrigerator, then the first control module 201 can control the first voltage conversion unit to supply power to the cooling load 30. If the refrigerator includes a cooling load 30 and an additional load 40, then the second voltage conversion unit or the third voltage conversion unit can be controlled to supply power to both the cooling load 30 and the additional load 40.

[0090] In some embodiments, the first control module 201 determines the target voltage conversion unit based on the total power of the cooling load 30 and the additional load 40 by detecting the number of additional loads 40 connected to the second control module 202 and then determining the target voltage conversion unit based on the number of additional loads 40.

[0091] For example, if the number of additional loads 40 is greater than a preset threshold, the target voltage conversion unit with higher output power is controlled to supply power to the cooling load 30 and the additional load 40; if the number of additional loads 40 is less than or equal to the preset threshold, the target voltage conversion unit with lower output power is controlled to supply power to the cooling load 30 and the additional load 40.

[0092] In some embodiments, when the second control module 202 detects that the second wiring harness is connected to a certain additional load 40, it can increment the number of additional loads 40 by one, and when it detects that the second wiring harness is disconnected from a certain additional load 40, it can decrement the number of additional loads 40 by one. Thus, the second control module 202 can count the number of connected additional loads 40 and thus determine the target voltage conversion unit.

[0093] It is understandable that by setting multiple voltage conversion units in the power supply module, the first control module can control the target voltage conversion unit to supply power to the cooling load and additional load according to the power requirements of different cooling loads and additional loads, thereby achieving targeted power supply for different loads and realizing the power supply compatibility of the power supply module.
