Description

Technical Field

[0001] The embodiments of the present application relate to the field of household appliances, and more specifically, to a refrigerator and a control method of the refrigerator. Background Art

[0002] As user needs continue to diversify, refrigerators have added many auxiliary functions in addition to the basic refrigeration function, such as sterilization, vacuum, fresh-keeping, wet and dry drawers, etc. In order to facilitate interactive operations with users, interactive functions are added in different temperature zones or drawers.

[0003] At present, the power supply for auxiliary functions or interactive functions is directly provided from the main control power supply part through the connecting line. When a short circuit occurs in the power supply part of the auxiliary function or interactive function, the entire power supply system of the refrigerator will be paralyzed, and the refrigerator will not be able to maintain the basic refrigeration function, causing food damage. Summary of the invention

[0004] The embodiment of the present application provides a refrigerator and a control method for a refrigerator, which can be used to solve the problem in the related art that when a short circuit occurs in the power supply part of an auxiliary function or an interactive function, the entire power supply system of the refrigerator will be paralyzed, the refrigerator will be unable to maintain basic refrigeration functions, and food will be damaged.

[0005] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0006] A refrigeration system, used for cooling the refrigerator;

[0007] A main control system connected to the refrigeration system, used to control the refrigeration system to refrigerate after the refrigerator is powered on;

[0008] A plurality of functional components connected to the main control system respectively through a plurality of preset switches, used to realize auxiliary functions of the refrigerator in addition to the refrigeration function; for any functional component, the preset switch corresponding to the functional component is used to control whether the main control system supplies power to the functional component;

[0009] The main control system is also used for:

[0010] After the refrigerator is powered on, initializing the states of the plurality of preset switches to be off;

[0011] Among the plurality of functional components, the state of the preset switch corresponding to the functional component that has not failed is closed, and the state of the preset switch corresponding to the functional component that has failed is closed.

[0012] In this embodiment, the refrigerator includes a refrigeration system for refrigerating the refrigerator, a main control system connected to the refrigeration system, and multiple functional components respectively connected to the main control system through multiple preset switches, wherein the main control system is used to control the refrigeration of the refrigeration system, and the multiple functional components are used to realize the auxiliary functions of the refrigerator other than the refrigeration function. For any functional component, the preset switch corresponding to the functional component is used to control whether the main control system supplies power to the functional component. The main control system is also used to initialize the states of the multiple preset switches to be disconnected after the refrigerator is powered on, and control the states of the preset switches corresponding to the functional components that have not failed to be closed, and the states of the preset switches corresponding to the functional components that have failed to be closed. The present application cuts off the faulty functional components by the preset switches, so that the refrigeration function can operate normally and reduce food damage.

[0013] In some embodiments of the present application, the main control system is specifically used for:

[0014] Determine the power failure reason before the refrigerator is powered on, wherein the power failure reason includes fault power failure and normal power failure;

[0015] According to the power failure reason, the states of the plurality of preset switches are controlled, the states being open or closed.

[0016] In this embodiment, by determining the cause of the power outage of the refrigerator, the state of the preset switch is controlled according to the cause of the power outage, so that the state of the preset switch is determined for different scenarios, thereby improving the control efficiency.

[0017] In some embodiments of the present application, the main control system is specifically used for:

[0018] If the power outage is caused by a fault, the target functional component that has failed is determined, the preset switch corresponding to the target functional component is controlled to remain open, and the preset switch corresponding to the functional component that has not failed is controlled to be closed.

[0019] In this embodiment, if the refrigerator is powered off due to a fault before being powered on, the faulty functional component can be determined and the preset switch of the faulty component can be disconnected to achieve the purpose of cutting off the power supply of the faulty component.

[0020] In some embodiments of the present application, the main control system is also used for:

[0025] In some embodiments of the present application, the main control system is specifically used for:

[0026] If the power failure reason is a normal power failure, the states of the plurality of preset switches are controlled to be closed.

[0027] In this embodiment, if the refrigerator is powered off normally before being powered on, then the functional components are likely not faulty. At this time, multiple preset switches can be directly closed so that multiple functional components can enter the working state when the operating conditions are met.

[0028] In some embodiments of the present application, if the power failure cause is a normal power failure, fault detection is performed on the multiple functional components;

[0029] If there is a faulty functional component, the preset switch corresponding to the faulty functional component is controlled to remain open, and the state of the preset switch corresponding to the functional component that has not failed is controlled to be closed;

[0030] If there is no faulty functional component, the states of the plurality of functional components are controlled to be closed.

[0031] In this embodiment, if the refrigerator is normally powered off before being powered on, functional components may also fail. In this case, fault detection can be performed on multiple functional components to avoid faulty functional components. After the preset switches are closed, the refrigerator will be powered off when the functional components are working.

[0032] In some embodiments of the present application, the main control system is also used for:

[0033] When a failure of a target functional component is detected, the refrigerator is controlled to be powered on after being powered off for a preset period of time.

[0034] In this embodiment, the refrigerator has a self-protection function. If a functional component fails during operation, the main control system can control the refrigerator to be powered off for a short period of time and then control the refrigerator to be powered on.

[0035] In some embodiments of the present application, for a first functional component among the multiple functional components that has an operating condition, the main control system is further configured to:

[0036] After the refrigerator is powered on, if the first functional component meets the operating conditions and the first functional component is a functional component without any faults, the first functional component is controlled to enter a working state.

[0037] In this embodiment, it is possible to prevent a faulty functional component from entering a working state when the operating conditions are met, thereby causing a power outage in the refrigerator.

[0040] A refrigeration system disposed in the box body, used for refrigerating the refrigerating chamber and the freezing chamber;

[0042] A plurality of functional components connected to the main control system respectively through a plurality of preset switches, used to realize auxiliary functions of the refrigerator in addition to the refrigeration function; for any functional component, the preset switch corresponding to the functional component is used to control whether the main control system supplies power to the functional component;

[0043] The main control system is also used for:

[0044] After the refrigerator is powered on, initializing the states of the plurality of preset switches to be off;

[0045] For any functional component, if the functional component meets the operating conditions, determine whether the functional component is a faulty component. If not, control the state of the preset switch corresponding to the functional component to be closed, and control the functional component to enter the working state.

[0046] In this embodiment, the refrigerator includes a refrigeration system for refrigerating the refrigerator, a main control system connected to the refrigeration system, and multiple functional components respectively connected to the main control system through multiple preset switches, wherein the main control system is used to control the refrigeration of the refrigeration system, and the multiple functional components are used to realize the auxiliary functions of the refrigerator other than the refrigeration function. For any functional component, the preset switch corresponding to the functional component is used to control whether the main control system supplies power to the functional component. The main control system is also used to initialize the states of the multiple preset switches to disconnect after the refrigerator is powered on. For any functional component, if the functional component meets the operating conditions, it is determined whether the functional component is a faulty component. If not, the state of the preset switch corresponding to the functional component is controlled to be closed, and the functional component is controlled to enter a working state. The present application cuts off the faulty functional component through the preset switch, so that the refrigeration function can operate normally and reduce food damage.

[0047] In a third aspect, the present application provides a control method for a refrigerator, the refrigerator comprising: a refrigeration system for refrigerating the refrigerator, a main control system connected to the refrigeration system, and a plurality of functional components respectively connected to the main control system through a plurality of preset switches;

[0066] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0067] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and common meanings.

[0068] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0069] At present, the power supply of each functional component is directly provided from the power supply part of the main control system through the connecting line. When a short circuit occurs in the power supply part of a functional component, the entire refrigerator will be cut off from power for a short period of time (for example, two minutes) due to self-protection, and then the refrigerator can automatically restart and power on. However, if a functional component has been in a short-circuit state, that is, it has not been repaired, then the refrigerator will be in a power-off state due to self-protection and cannot be restarted, which will cause the entire power system of the refrigerator to be paralyzed, and the refrigerator will be unable to maintain basic refrigeration functions, causing food damage.

[0070] In order to solve the above problems, the present application provides a refrigerator, in which a preset switch is set between each functional component and the power supply of the main control system, so that after the refrigerator is powered on, the preset switches corresponding to each functional component are first disconnected, and then the preset switches corresponding to the functional components with faults are kept disconnected, and the preset switches corresponding to the functional components that have not failed are closed, so that the functional components that have not failed can enter the working state when the operating conditions are met, and the functional components that have failed cannot enter the operating state, which can avoid the situation where the refrigerator is powered off due to a fault, so that the refrigeration function and the functional components that have not failed can operate normally, reducing food damage.

[0071] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other or exist independently. The same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0072] Figure 1 A schematic diagram of the structure of a refrigerator provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the refrigerator 10 includes a refrigeration system 101 , a main control system 102 connected to the refrigeration system 101 , and a plurality of functional components 104 respectively connected to the main control system 102 via a plurality of preset switches 103 .

[0073] The refrigeration system 101 refrigerates the refrigerator 10 . Specifically, the refrigeration system 101 may refrigerate a refrigerating chamber and a freezing chamber disposed in the body of the refrigerator 10 .

[0074] The main control system 102 is used to control the refrigeration system 101 to refrigerate after the refrigerator 10 is powered on.

[0075] Multiple functional components 104 are used to realize auxiliary functions of the refrigerator 10 except the refrigeration function. For any functional component, the preset switch corresponding to the functional component is used to control whether the main control system 102 supplies power to the functional component. That is, when the preset switch is disconnected, the main control system 102 does not supply power to the functional component (that is, the power supply of the functional component is disconnected). When the preset switch is closed, the main control system 102 can supply power to the functional component.

[0076] Exemplarily, the plurality of functional components 104 may include: a plurality of auxiliary functional components and a plurality of interactive functional components;

[0077] Multiple auxiliary functional components include: sterilization component, preservation component, vacuum component, humidification component, dry and wet storage drawers, etc.

[0078] Multiple interactive functional components include: display component, communication component, voice interaction component, etc.

[0079] Among them, the sterilization component can sterilize the refrigerator.

[0080] The fresh-keeping component can extend the shelf life of food and prevent food from spoiling through dehumidification, sterilization and cooling technology.

[0081] The vacuum component can expel oxygen from food by vacuuming it, preventing the generation of bacteria and oxidation, thereby achieving the purpose of preserving food.

[0082] The humidifying component can increase the humidity inside the refrigerator 10 to maintain the freshness and taste of vegetables and fruits.

[0083] Dry and wet storage drawers can be used to store foods with certain humidity requirements, such as dry goods, fruits and vegetables, etc.

[0084] The display component may be a display screen provided on the door of the refrigerator 10 , through which the user may interact with the refrigerator 10 .

[0085] Communication component, the user can interact with the refrigerator through the communication component, for example, the user can interact with the refrigerator through the terminal application.

[0086] Voice interaction component, users can interact with the refrigerator through voice control component, such as controlling the opening of each functional component or adjusting the temperature through voice.

[0087] The main control system 102 is also used for:

[0088] After the refrigerator 10 is powered on, the states of the plurality of preset switches 103 are initialized to be off.

[0089] Among the multiple functional components 104, the states of the preset switches corresponding to the functional components that have not failed are closed, and the states of the preset switches corresponding to the functional components that have failed remain open.

[0090] That is, no matter what the reason for the power failure of the refrigerator 10, after the refrigerator 10 is powered on, the states of the plurality of preset switches 103 are initialized to be off, so that after the refrigerator 10 is powered on, the plurality of functional components 104 are first in a power-off state. Then, the main control system 102 sets the states of the corresponding preset switches according to whether the functional components have failed, so that the power of the functional components that have not failed is turned on, and the power of the functional components that have failed remains off.

[0091] For example, Figure 2 As shown, the main control system 102 includes a refrigeration control module 21, a power system 22 and a main controller 23. The main controller 23 can supply power to the refrigeration system 101 through the power system 22, and control the operation of the refrigeration system 101 through the refrigeration control module 21 to achieve refrigeration. The main controller 23 is connected to a plurality of preset switches 103 to control the closing or opening of the plurality of preset switches 103. It can be understood that in order to control the operation of each functional component, the main controller 23 is connected to each functional component, which is not shown in the figure.

[0092] The main controller 23 may be a microcontroller unit (MCU), and the refrigeration control module 21 may be implemented by software, hardware, or a combination of software and hardware, which is not limited in the present application.

[0093] In a possible implementation, the preset switch may be a transistor.

[0094] For example, since the transistor is a current-type control component, the input voltage requirement of the control end required for the transistor to be turned on is relatively low, generally 0.4V to 0.6V (volts) or above can achieve transistor conduction. The main control system 102 can send a control signal to the base to control the base current limiting resistor to change the base current, thereby achieving control of the state of the transistor.

[0095] For example, Figure 3 This is a schematic diagram of a preset switch structure exemplified in this application. Figure 3 The current limiting resistor is used to reduce the current in the circuit, and the pull-down resistor is used to connect an uncertain signal to the functional component through the resistor and fix it at a low level.

[0096] In a possible implementation, the preset switch may be a metal-oxide semiconductor field-effect transistor, MOSFET for short, or MOS for short.

[0097] The MOSFET is a voltage-controlled component. The voltage required for conduction is generally about 4V to 10V. The main control system 102 sends a control signal to the gate to control the voltage of the MOSFET, thereby achieving control over the state of the MOSFET.

[0098] For example, Figure 4 This is a schematic diagram of the structure of another exemplary preset switch of the present application. The main control system 102 can control the voltage of the gate to achieve control of its state.

[0099] It can be understood that the preset switch can also be other devices or controllable switches that can be used as switches and can be automatically controlled to be on and off, and this application does not limit this.

[0100] In a possible implementation, for a first functional component having an operating condition among the plurality of functional components 104, the main control system 102 is further configured to:

[0101] After the refrigerator is powered on, if the first functional component meets the operating conditions and the first functional component is a functional component without any fault, the first functional component is controlled to enter the working state, so as to avoid the faulty functional component entering the working state when the operating conditions are met, causing the refrigerator to be powered off.

[0102] That is to say, the main control system 102 can monitor the first functional component, and when the first functional component meets the operating conditions and is a functional component without any faults, the first functional component is controlled to enter a working state.

[0103] In a possible implementation, the main control system 102 is also used to control the refrigerator to power on after the refrigerator is powered off for a preset period of time when a failure of a target functional component is detected.

[0104] In this embodiment, the refrigerator has a self-protection function. If a functional component fails during operation, the main control system 102 can control the refrigerator to be powered off for a short period of time and then control the refrigerator to be powered on. The preset time period can be, for example, 2 minutes.

[0105] In this embodiment, the refrigerator 10 includes a refrigeration system 101 for refrigerating the refrigerator, a main control system 102 connected to the refrigeration system 101, and multiple functional components 104 respectively connected to the main control system 102 through multiple preset switches 103, wherein the main control system 102 is used to control the refrigeration of the refrigeration system 101, and the multiple functional components 104 are used to realize the auxiliary functions of the refrigerator in addition to the refrigeration function. For any functional component, the preset switch corresponding to the functional component is used to control whether the main control system 102 supplies power to the functional component. The main control system 102 is also used to initialize the state of the multiple preset switches 103 to disconnect after the refrigerator is powered on, and control the state of the preset switches corresponding to the functional components that have not failed in the multiple functional components 104 to be closed, and the state of the preset switches corresponding to the functional components that have failed to be closed. In this application, when a short circuit fault occurs in a functional component, the preset switch cuts off the faulty functional component, so that the refrigeration function can operate normally and reduce food damage.

[0106] Based on the above refrigerator, Figure 5 A flowchart of a refrigerator control method provided in an embodiment of the present application is provided. The execution subject of the method may be a main control system, such as Figure 5 As shown, the method includes the following steps.

[0107] S501, determining the reason for a power outage before the refrigerator is powered on, where the power outage reason includes a fault power outage and a normal power outage.

[0108] The reason for the power failure of the refrigerator before powering on may be due to a short circuit failure of a functional component, hereinafter referred to as a fault power failure, or it may be a normal power failure, such as a power outage or the user unplugging the refrigerator, causing the refrigerator to lose power.

[0109] If the refrigerator is powered off normally, the various functional components may not necessarily fail. If the refrigerator is powered off due to a fault, there may be a functional component with a short circuit failure among the multiple functional components of the refrigerator.

[0110] S502: According to the power failure reason, control the status of multiple preset switches, the status being open or closed.

[0111] After determining the cause of the power outage, the main control system can control the states of multiple preset switches according to the cause of the power outage.

[0112] In other words, the status of multiple preset switches can be controlled based on different power outage scenarios. For example, if the refrigerator is powered off normally, the various functional components may not necessarily fail. In this scenario, it is not necessary to judge whether multiple functional components have failed, that is, the preset switches corresponding to the multiple functional components can be directly closed.

[0113] In an embodiment, the cause of a power outage of the refrigerator can be determined and the state of a preset switch can be controlled according to the cause of the power outage, so that the state of the preset switch can be determined for different scenarios, thereby improving control efficiency.

[0114] Next, it is explained how the main control system controls the states of multiple preset switches for different power failure reasons.

[0115] Figure 6 A flowchart of another refrigerator control method provided in an embodiment of the present application is provided. The execution subject of the method may be a main control system, such as Figure 6 As shown, the method includes the following steps.

[0116] S601: After the refrigerator is powered on, the states of multiple preset switches are controlled to be initialized to be disconnected.

[0117] S602: Determine whether the power failure before the refrigerator is powered on is caused by a fault.

[0118] If the power outage is caused by a fault, S603 is executed. If the power outage is not caused by a fault, that is, the power outage is caused by a normal power outage, S605 is executed.

[0119] Exemplarily, the refrigerator can monitor and record the cause of the power outage. For example, if the refrigerator loses power due to a short circuit failure in a functional component, the refrigerator can record the cause of the power outage as a faulty power outage. For example, 1 can be used to record the cause of the power outage. If the power supply to the refrigerator is disconnected, such as a power outage or the user unplugging the refrigerator, the refrigerator can record the cause of the power outage as a normal power outage. For example, 0 can be used to record the cause of the power outage.

[0120] S603: Determine the target functional component where the failure occurs.

[0121] If the power outage is caused by a fault, the main control system can determine the target functional component where the fault occurs, so as to control the state of a preset switch corresponding to the faulty functional component.

[0122] S604: Control the preset switch corresponding to the target functional component to remain open, and control the preset switch corresponding to the functional component that has not failed to close.

[0123] S605: Control the states of multiple preset switches corresponding to the multiple functional components to be closed.

[0124] If the power failure is caused by a normal power failure, and the multiple functional components are likely not to have failed, the main control system can control the states of the multiple preset switches to be closed, so that the multiple functional components can enter a working state.

[0125] In this embodiment, the main control system can determine whether the power failure reason before the refrigerator is powered on is a fault power failure. If so, the target functional component with the fault can be determined, and the preset switch corresponding to the target functional component can be controlled to remain open, and the preset switch corresponding to the functional component that has not failed can be controlled to be closed. If not, the state of multiple preset switches can be controlled to be closed. By controlling the state of the preset switch according to the power failure reason of the refrigerator, the state of the preset switch can be determined for different scenarios, thereby improving the efficiency of control.

[0126] Figure 7 A flowchart of another refrigerator control method provided in an embodiment of the present application is provided. The execution subject of the method may be a main control system, such as Figure 7 As shown, the method includes the following steps.

[0127] S701: After the refrigerator is powered on, the states of multiple preset switches are controlled to be initialized to be off.

[0128] S702: Determine whether the power failure before the refrigerator is powered on is caused by a fault.

[0129] If the power outage is caused by a fault, then S703 is executed. If the power outage is not caused by a fault, that is, the power outage is caused by a normal power outage, then S705 is executed.

[0130] S703: Determine the target functional component where the failure occurs.

[0131] S704: Determine whether the target functional component is repaired.

[0132] If yes, execute S705, if no, execute S706.

[0133] Before the refrigerator is powered on, the target functional component of the refrigerator may be repaired, for example, by a maintenance person.

[0134] S705: Control the states of preset switches corresponding to the plurality of functional components to be closed.

[0135] S706: Control the state of the preset switch corresponding to the target functional component to be open, and control the state of the preset switch corresponding to the functional component that has not failed to be closed.

[0136] In this embodiment, the main control system can determine whether the power failure cause before the refrigerator is powered on is a fault power failure. If so, the target functional component that has failed can be determined, and it can be determined whether the target functional component has been repaired. If it has been repaired, the state of the preset switches corresponding to the multiple functional components is controlled to be closed. If it has not been repaired, the state of the preset switches corresponding to the target functional components is controlled to be open, and the state of the preset switches corresponding to the functional components that have not failed is controlled to be closed. If the power failure cause is not a fault power failure, the state of multiple preset switches can be controlled to be closed. By controlling the state of the preset switches according to the power failure cause of the refrigerator, it is avoided that the faulty functional component has been repaired but cannot enter the working state.

[0137] Figure 8 A flowchart of another refrigerator control method provided in an embodiment of the present application is provided. The execution subject of the method may be a main control system, such as Figure 8 As shown, the method includes the following steps.

[0138] S801: After the refrigerator is powered on, the states of multiple preset switches are controlled to be initialized to be disconnected.

[0139] S802: Determine whether the power failure before the refrigerator is powered on is caused by a fault.

[0140] If the power outage is caused by a fault, then S803 is executed. If the power outage is not caused by a fault, that is, the power outage is caused by a normal power outage, then S807 is executed.

[0141] S803: Determine the target functional component where the failure occurs.

[0142] S804: Determine whether the target functional component is repaired.

[0143] If yes, execute S805, if no, execute S806.

[0144] S805: Control the states of preset switches corresponding to the plurality of functional components to be closed.

[0145] S806: Control the state of the preset switch corresponding to the target functional component to be open, and control the state of the preset switch corresponding to the functional component that has not failed to be closed.

[0146] S807: Perform fault detection on multiple functional components to determine whether there is a faulty functional component.

[0147] If yes, execute S806, if no, execute S805.

[0148] In this embodiment, the main control system can determine whether the power failure before the refrigerator is powered on is caused by a fault. If so, the target functional component that has failed can be determined, and it can be determined whether the target functional component has been repaired. If it has been repaired, the preset switches corresponding to the multiple functional components are controlled to be closed. If it has not been repaired, the preset switches corresponding to the target functional components are controlled to be open, and the preset switches corresponding to the functional components that have not failed are controlled to be closed. If the power failure is not caused by a fault, the functional components may also fail. In this case, fault detection can be performed on multiple functional components to avoid a faulty functional component. After the preset switches of the faulty functional components are closed, the refrigerator will be powered off when the functional components are working.
