[0069] 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.

[0070] 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 common and usual meanings.

[0071] 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.

[0072] The display panel installed on the refrigerator is relatively small in size. The display screen in the display panel usually uses a thin film field effect transistor (TFT) liquid crystal display. Considering the production cost and display function, the display panel is generally controlled by a low-cost processor or a single-chip microcomputer.

[0073] As the functions of refrigerators increase, in order to solve the problem of insufficient physical buttons on the display panel, usually for a button, the user can long press or short press to control different functions. For example, when the display screen is in lock state, the user can long press the button to unlock it, while a short press will keep it locked, that is, the unlocking fails.

[0074] However, as the functions of refrigerators increase, the above method is difficult to meet the interactive needs. At present, in order to meet this demand, some refrigerators use Android screens or Linux screens for display panels, but these display screens require high-performance controller support, resulting in increased production costs for refrigerator display panels.

[0075] Then, how to expand the buttons to satisfy the user's interaction with multiple functions of the refrigerator is an urgent problem to be solved.

[0076] Therefore, the present application provides a refrigerator, which adds extended buttons and corresponding control components on the display panel so that the control components communicate with the main control component (i.e., the first control component) to control functions other than the functions corresponding to the original touch buttons on the display panel of the refrigerator, and the display screen still uses a TFT liquid crystal display, so that the extended buttons are controlled by a low-cost processor or single-chip microcomputer (i.e., the second control component) to reduce the manufacturing cost of the display panel of the refrigerator.

[0077] 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.

[0078] First, the specific structure of a refrigerator provided in an embodiment of the present application is described. 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 cabinet 101 , a door 102 and a display panel 103 .

[0079] A storage room is provided in the box body 101, and the storage room may include a refrigerating room, a freezing room, etc. The door body 102 is used to open or close the storage room.

Figure 1 The refrigerator 10 in the example is a double-door refrigerator, and the display panel 103 can be set on any one of the two door bodies. It can be understood that the refrigerator 10 can also be other types, and the present application does not limit the type of refrigerator 10.

[0081] Figure 2 A schematic diagram of the structure of a display panel 103 provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the display panel 103 includes a main display panel 104 and a key expansion panel 105 .

[0082] The main display panel 104 includes a plurality of touch buttons 41 , a first control component 42 and a display screen 43 .

For any touch button, the touch button is configured to control the activation of the function corresponding to the touch button when the touch button is triggered. That is, the user can press the touch button to control the activation of the function corresponding to the touch button.

[0084] The first control component 42 is connected to the plurality of touch buttons 41 and the display screen 43 respectively.

[0085] The key expansion board 105 includes multiple extension keys 51 and a second control component 52. The second control component 52 is respectively connected to the multiple extension keys 51 and the first control component 42. For any extension key, the extension key is configured to control the start of the function corresponding to the extension key when the extension key is triggered. The function corresponding to the extension key is a function other than the functions corresponding to the multiple touch keys.

[0086] A plurality of extended keys 51 may be provided in a key extension area of ​​the display panel 103 .

[0087] The second control component 52 is configured to send control information to the first control component when detecting that a target extension key is triggered. The target extension key is one of the multiple extension keys 51 .

[0088] The first control component 42 is configured to:

[0089] When it is detected that the target touch key is triggered, the function corresponding to the target touch key is started, or, according to the control information, the function corresponding to the target extended key is started, wherein the target touch key is one of the multiple touch keys 41 .

[0090] Figure 3 Schematic diagram of the display panel 103 on the door body 102 of the present application example. It can be understood that Figure 3 The numbers of touch keys in the middle key area and the key extension area are just examples.

[0091] In this embodiment, the refrigerator 10 includes a box body 101 provided with a storage chamber, a door body 102 for opening or closing the storage chamber, and a display panel 103 provided on the door body, the display panel 103 includes a main display panel 104 and a key expansion panel 105, the main display panel 104 includes a plurality of touch keys 41, a first control component 42 and a display screen 43, the first control component 42 is respectively connected to the plurality of touch keys 41 and the display screen 43, for any touch key, the touch key is configured to control the activation of the function corresponding to the touch key when the touch key is triggered. The key expansion panel 105 includes a plurality of extension keys 51 and a second control component 52, the second control component 52 is respectively connected to the plurality of extension keys 51 and the first control component 42, for any extension key, the extension key is configured to control the activation of the function corresponding to the extension key when the extension key is triggered, and the function corresponding to the extension key is a function other than the functions corresponding to the plurality of touch keys. The second control component 52 is configured to send control information to the first control component 42 when it detects that the target expansion button is triggered. The first control component 42 is configured to start the function corresponding to the target touch button when it detects that the target touch button is triggered, or to start the function corresponding to the target expansion button according to the control information, thereby solving the problem of insufficient physical buttons on the display panel of the refrigerator.

[0092] Based on the above display panel 103, Figure 4 A flowchart of a method for controlling a refrigerator display panel provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the method may include the following steps:

[0093] S401. When the second control component detects that a target extension key is triggered, the second control component starts a timing function, where the timing function is used to time a first touch duration of the target extension key.

[0094] When it is detected that the target expansion key is triggered, that is, when it is detected that the user presses the target expansion key, the first control component can time the first touch duration of the target expansion key.

[0095] S402: When the target extended key is released from touch, the second control component determines a first touch duration.

[0096] S403: The second control component generates control information according to the first touch duration and the first identifier of the target extended key.

[0097] After determining the duration for which the target extension key is pressed by the user, the second control component may generate control information according to the first touch duration and the first identifier of the target extension key.

[0098] In a possible implementation, the second control component can determine the first state of the target extended key according to the first touch duration, the first state being a long press state or a short press state, and then generate control information according to the first state and the first identifier.

[0099] Specifically, if the first touch duration is less than a preset duration, the first state is determined to be a short press state, and if the first touch duration is longer than the preset duration, the first state is determined to be a long press state.

[0100] Exemplarily, the preset duration may be 3 seconds. When the first touch duration is less than 3 seconds, the first state may be determined to be a short press state. If the first touch duration is longer than 3 seconds, the first state may be determined to be a long press state.

[0101] By sending the first state of the target extension key to the first control component, the first control component can activate the function of the target extension key in the long press state or the short press state.

[0102] In this embodiment, when the second control component detects that the target extension key is triggered, it starts the timing function, and the timing function is used to time the first touch duration of the target extension key. Then, when the target extension key is released from touch, the second control component determines the first touch duration, and generates control information based on the first touch duration and the first identifier of the target extension key, so as to realize control of the corresponding function of the extension key through the second control component.

[0103] In one possible implementation, if the target extension component is a single-function button, that is, there is no long press state or short press state, the control information sent by the second control component to the first control component includes a first identifier, and the first control component directly determines the target extension button among multiple extension buttons based on the first identifier to start the function corresponding to the target extension button.

[0104] In a possible implementation, the first control component and the second control component may be connected via a serial port to achieve communication.

[0105] Then, when transmitting control information, data transmission errors may occur due to hardware, software or environmental reasons, and the refrigerator startup function may not match the function corresponding to the target expansion button, affecting the user experience.

[0106] In order to solve the above problems, Figure 5 A flow chart of another method for controlling a refrigerator display panel provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the method may include the following steps:

[0107] S501. A first control component generates a first verification code according to a first state and a first identifier in control information.

[0108] In a possible implementation manner, the control information may include a target check code, where the target check code is generated according to the first state and the first identifier.

[0109] Exemplarily, the control information may be transmitted in the form of a data frame of multiple bytes, as shown in Table 1, where 7 bytes and 16 extended keys are taken as an example.

[0110] Table 1

[0111]

[0112] Among them, Byte1 is the frame header of the data frame, Byte2 is a reserved bit, generally set to 0000, Byte3, Byte4, Byte5 and Byte6 are used to indicate the first state corresponding to different extended keys, and Byte7 is used to indicate the target check bit.

[0113] For the sake of illustration, Byte3, Byte4, Byte5 and Byte6 are exemplified below:

[0114] When the binary bits of Byte3, Byte4, and Byte5 are all 0, the binary bits corresponding to Byte6 are: 0000 0001, which means that button 0 is in short press state.

[0115] When the binary bits of Byte3, Byte4, and Byte5 are all 0, the binary bits corresponding to Byte6 are: 0000 0010, which means that button 1 is in short press state.

[0116] When the binary bits of Byte3, Byte4, and Byte6 are all 0, and the binary bits of Byte5 are all: 0000 1000, it means that button 11 is in short press state.

[0117] When the binary bits of Byte3, Byte5, and Byte6 are all 0, and the binary bits of Byte4 are all: 0000 0001, it means that button 0 is in the long press state.

[0118] The first states corresponding to other extended keys are similar and will not be described in detail here.

[0119] In a possible implementation, the first identifier includes multiple button identifiers, and the first control component can determine the combination extension button corresponding to the multiple button identifiers, and start the function corresponding to the combination extension button to achieve control of more functions through the form of combination buttons.

[0120] For example, the user can press button 1 and button 2 at the same time to start function A.

[0121] Taking the data frame in Table 1 as an example, when the binary bits of Byte3, Byte5, and Byte6 are all 0, and the binary bits of Byte4 are all: 0000 0011, it means that button 0 and button 1 are in the long press state at the same time, which means that button 0 and button 1 are combination buttons, which are used to start a certain function in the long press state at the same time.

[0122] It should be understood that the combination key can be a combination of an extension key and a touch key, and the first control component can activate the function corresponding to the combination key according to the second state of the triggered touch key and the first state of the triggered extension key.

[0123] In one possible implementation, the target check code can be calculated by the second control component based on the binary code corresponding to Byte3, Byte4, Byte5 and Byte6 in the data frame corresponding to the control information. The present application does not limit the method of calculating the target check code based on the binary code, for example, it can be addition or other calculation methods.

[0124] Then, after receiving the control information, the first control component may generate the first verification code according to the way in which the second control component generates the target verification code.

[0125] S502: The first control component determines whether the control information is transmitted incorrectly according to the first check code and the target check code.

[0126] After the first check code is generated, the first control component can determine whether the control information is transmitted incorrectly based on the first check code and the target check code.

[0127] In a possible implementation, if the first check code is different from the target check code, it is determined that the control information is transmitted incorrectly. If the first check code is the same as the target check code, it is determined that the control information is transmitted correctly.

[0128] S503: If the control information is transmitted incorrectly, the first control component sends a feedback signal to the second control component, where the feedback signal is used to instruct the second control component to resend the control information.

[0129] If the control information is transmitted incorrectly, the first control component sends a feedback signal to the second control component, where the feedback signal is used to indicate that the control information is transmitted incorrectly, and the second control component may resend the control information.

[0130] If the control information is transmitted correctly, the first control component can further control according to the control information.

[0131] In this embodiment, the first control component generates a first verification code according to the first state and the first identifier in the control information, and then determines whether the control information is transmitted incorrectly according to the first verification code and the target verification code. If the control information is transmitted incorrectly, the first control component sends a feedback signal to the second control component, and the feedback signal is used to instruct the second control component to resend the control information. The verification code is used to verify whether the data transmission between the first control component and the second control component is erroneous, thereby avoiding the occurrence of errors in key function control.

[0132] Figure 6 A flow chart of another method for controlling a refrigerator display panel provided in an embodiment of the present application is shown as follows: Figure 6 As shown, the method may include the following steps:

[0133] S601: When the first control component detects that a target touch key is triggered, the first control component starts a timing function, where the timing function is used to time a second touch duration of the target touch key.

[0134] S602: When the target touch key is released from touch, the first control component determines a second touch duration.

[0135] S603: The first control component determines a second state corresponding to the target touch key according to the second touch duration, where the second state is a long press state or a short press state.

[0136] S604: The first control component activates a function corresponding to the target touch button in the second state.

[0137] In this embodiment, the first control component determines whether the touch key is long pressed or short pressed based on the touch duration of the touch key, so as to realize the control of different functions.

[0138] In a possible implementation, the first control component may start the function corresponding to the target touch key or the target extension key in the following manner:

[0139] Figure 7 A schematic diagram of the structure of a refrigerator provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, the refrigerator further includes a main control board 106, which is connected to the first control component 42. The first control component 42 can send a control signal to the main control board 106 according to the control information, so that the main control board 106 can start the function of the target expansion key in the first state or the corresponding function of the target touch key in the second state based on the control signal. For example, the target expansion touch key is an unlocking key, which can be unlocked in a long press state and remains locked in a short press state, that is, not unlocked.

[0140] In a possible implementation, the display screen 43 may be a TFT liquid crystal display, and accordingly, the first control component 32 and the second control component 35 may be a low-cost processor or microcontroller unit (MCU), which may be called a single-chip microcomputer. By controlling the display screen 43 through a low-cost control component, the manufacturing cost of the refrigerator display panel may be further reduced.
