[0068] 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.

[0069] 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.

[0070] 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.

[0071] At present, it has become an industry trend to integrate display screens on refrigerators to present better display effects. For example, 21.5-inch, 10-inch and 7-inch display screens have been used on refrigerators. These large-size display screens can present better display effects, but the production cost of refrigerators is relatively high. Small-size display screens, due to their small display area, do not match the large area of ​​refrigerators, and their display effects on refrigerators are poor, so they are not widely used in refrigerators.

[0072] Therefore, how to improve the display effect when setting a small-sized display screen on a refrigerator is an urgent problem to be solved.

[0073] Therefore, the present application provides a refrigerator. By adding an extended button and a corresponding control component on the display module, the control component communicates with the main control component (i.e., the first control component), and can control the small-size display screen and the extended color film button to light up or go out synchronously, so that the display module of the refrigerator can achieve integrated display while increasing the display area, thereby improving the display effect of the display module on the refrigerator.

[0074] 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.

[0075] First, the specific structure of a refrigerator provided in an embodiment of the present application is described. Figure 1A 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 module 103 .

[0076] 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.

[0077] The display module 103 is disposed on the door body 102. Specifically, Figure 1 As shown, the display module 103 is arranged on the side facing the user, so that the user can control the corresponding functions of the refrigerator 10 through the display module 103 when using the refrigerator. Figure 1 The refrigerator 10 in the example is a double-door refrigerator, and the display module 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.

[0078] Figure 2 A schematic diagram of the structure of a display module 103 provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the display module 103 includes a main display panel 104 and a key expansion panel 105 .

[0079] The main display panel 104 includes a plurality of touch buttons 41 , a first control component 42 and a display screen 43 .

[0080] Multiple touch buttons 41 can be set in the button area of ​​the display module 103. 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 control the activation of the function corresponding to the touch button by pressing the touch button.

[0081] The first control component 42 is connected to the plurality of touch buttons 41 and the display screen 43 respectively.

[0082] The key expansion board 105 includes a plurality of color film keys 51, a second control component 52, and a light emitting component 53 disposed under the plurality of color film keys 51. The second control component 52 is respectively connected to the plurality of color film keys 51 and the first control component 42, and the light emitting component 53 is connected to the second control component 52, and is configured to illuminate the plurality of color film keys 51 when it is lit, that is, the light emitting component 53 can be disposed on the back of the plurality of color film keys 51, so that when the light emitting component 53 is lit, the plurality of color film keys 51 can be illuminated.

[0083] Among them, multiple color film buttons 51 can be set in the button extension area of ​​the display module 103. For any color film expansion button, the color film expansion button is configured to control the activation of the function corresponding to the color film button when the color film button is triggered, and the function corresponding to the color film button is a function other than the functions corresponding to the multiple touch buttons.

[0084] Exemplarily, the light-emitting component 53 may be a light-emitting diode (LED), or may be other devices that can emit light, which is not limited in the present application.

[0085] The second control component 52 is configured to: send control information to the first control component 42 according to the first state of the display module 103, and control the light-emitting component 53 to be in the second state, the first state is the unlocked state or the locked screen state, the second state is lit or off, and the control information includes the second state.

[0086] The first control component 42 is configured to: control the display screen 43 to be in the second state according to the control information, so that the state of the light-emitting component 53 is consistent with the state of the display screen 43, which can prevent the display screen 43 from lighting up but the color film part is not lighting up, or the display screen 43 is off but the color film part is not off, resulting in a poor user experience.

[0087] It can be understood that when the first state of the display module 103 is the lock screen state, the user cannot control the refrigerator through the main display panel 104 and the key expansion panel 105. After unlocking, the refrigerator can be controlled through the main display panel 104 or the key expansion panel 105.

[0088] Understandably, Figure 2 It is only a schematic diagram of the structure of the display module 103 , and does not limit the positions of the first control component 42 , the multiple touch buttons 41 , the display screen 43 , the second control component 52 , the multiple color film buttons 51 and the light-emitting component 53 in the display module 103 .

[0089] Figure 3 Schematic diagram of the display module 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.

[0090] 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 module 103 provided on the door body. The display module 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 connected to the plurality of touch keys 41 and the display screen 43, respectively. The key expansion panel 105 includes a plurality of color film keys 51, a second control component 52, and a light emitting component 53 provided on the back of the plurality of color film keys 51. The light emitting component 53 is configured to illuminate the plurality of color film keys 51 when it is lit. The second control component 52 is configured to send control information to the first control component 42 according to the first state of the display module 103, and control the light emitting component 53 to be in the second state. The first control component 42 is configured to control the display screen 43 to be in the second state according to the control information, so that the state of the light emitting component 53 is consistent with the state of the display screen. The present application controls the button expansion panel 105 and the main display panel 104 to light up or go out synchronously, so that the display module 103 can achieve integrated display while increasing the display area, thereby improving the display effect of the display module 103 on the refrigerator.

[0091] In a possible implementation, the key expansion board 105 further includes a sensing component 54. Figure 4 A schematic diagram of the structure of another display module 103 provided in an embodiment of the present application, wherein the sensing component 54 is connected to the second control component 53, and the sensing component 54 is configured to detect a preset area of ​​the environment where the refrigerator 10 is located, and when a user is detected approaching the refrigerator, a sensing signal can be sent to the second control component 52, and the sensing signal is used to indicate that the user is approaching the refrigerator. Exemplarily, the preset area can be the detectable range of the sensing component 54 on the side of the door body 102 facing the user.

[0092] Exemplarily, the sensing component 54 may be an infrared sensor (Passive infrared detectors, PIR), or other devices that can detect the human body, and the present application does not limit this.

[0093] The second control component 52 is configured to control the display screen 43 and the light-emitting component 53 to light up at the same time according to the sensing signal when the display module 103 is locked, so that when the user approaches the refrigerator and the display module 103 is in the locked state, the light-emitting component 53 and the display screen 43 are controlled to light up at the same time.

[0094] Based on the above display module 103, Figure 5 A flow chart of a method for controlling a display module of a refrigerator provided in an embodiment of the present application can be executed by a second control component, such as Figure 5 As shown, the method may include the following steps:

[0095] S501: When the first state of the display module is the screen lock state, determine, according to the sensing signal, that the second state of the display screen is lighting, and send control information to the first control component.

[0096] When the display model is in the locked screen state and no user is operating the refrigerator, the display screen and the light-emitting component are both off. When the display module receives the sensing signal sent by the sensing module, it can be determined that a user is approaching the refrigerator. In order to improve the user experience, the second control component can determine that the second state of the display screen is lit based on the sensing signal, and send control information to the first control component.

[0097] It can be understood that the second state included in the control information can be a lighting mark. For example, when the second state is 1, it means lighting, and when the second state is 0, it means off. In this case, the second state in the control information can be 1.

[0098] S502, controlling the second state of the light-emitting component to be lit.

[0099] After sending a control signal to the first control component, the second control component can control the second state of the light-emitting component to be lit, that is, the light-emitting component is lit so that the plurality of color film buttons and the display screen are lit at the same time.

[0100] Exemplarily, in order to ensure that the light-emitting component and the display screen light up at the same time, for example, it takes 0.1s for the second control component to send control information to the first control component. Then, the first control component lights up the display screen at the moment of receiving the control information. Then, the second control component can light up the light-emitting component 0.1s after sending the control information, so that the light-emitting component and the display screen light up at the same time. It can be understood that the light-emitting component can be lit according to the brightness of the display module in the lock screen state, the display screen can be lit according to the brightness, and the interface required to be displayed under the lock screen can also be displayed.

[0101] In this embodiment, when the display module is in a locked state, when it is sensed that a user is approaching the refrigerator, the light-emitting component and the display screen can be controlled to light up at the same time, so that the user can perform corresponding operations based on the lit display module, thereby improving the user experience.

[0102] In one possible implementation, after the user approaches the refrigerator so that the display screen and the light-emitting component light up, the display screen can display a lock screen prompt message, such as "Currently locked, please press key a to unlock."

[0103] In another possible implementation, after the user approaches the refrigerator so that the display screen and the light-emitting component light up, the second control component can prompt the user to unlock the refrigerator in the following manner:

[0104] Figure 6A flow chart of another method for controlling a display module of a refrigerator provided in an embodiment of the present application is shown as follows: Figure 6 As shown, the method may include the following steps:

[0105] S601: After the light-emitting component and the display screen are lit, if the second control component detects that any one of the plurality of color film buttons is triggered, it sends indication information to the first control component.

[0106] The indication information is used to instruct the display screen to display the lock screen prompt information, and the lock screen prompt information is used to prompt the user that the current display module is in the lock screen state. For example, the lock screen indication information may be "Currently in the locked state, please press key a to unlock."

[0107] S602: The first control component displays lock screen indication information according to the indication information.

[0108] In this embodiment, after the user approaches the refrigerator and causes the display screen and the light-emitting component to light up, if the second control component detects that the user has triggered a color film button, indicating that the user needs to control the refrigerator, the display screen can be controlled to display a lock screen indication message to prompt the user to unlock the refrigerator. This can avoid the situation where the user is just passing by the refrigerator but does not need to control the refrigerator, in which case there is no need to display the lock screen indication message.

[0109] In a possible implementation, after the user unlocks the device, that is, after the first state of the display module is switched from the locked screen state to the unlocked state, the second control component may monitor whether the user triggers the color film button, specifically:

[0110] If the second control component detects that the target color film button is triggered, that is, when the user presses the target color film button, the second control component can send a first message to the first control component, and the first message can be used to instruct the first control component to start the function corresponding to the target color film button.

[0111] Exemplarily, the first information may include an identifier of a target color film button, and the first control component determines the function of the target color film button from functions corresponding to a plurality of color film buttons according to the identifier to activate the function corresponding to the target color film button.

[0112] In a possible implementation, if the target color film component is a multi-function button, for example, the target color film button corresponds to different functions in a long press state and a short press state, respectively, the second control component can generate the first information in the following manner:

[0113] Figure 7 A flow chart of another method for controlling a display module of a refrigerator provided in an embodiment of the present application is shown as follows: Figure 7 As shown, the method may include the following steps:

[0114] S701: When it is detected that a target color film key is triggered, a timing function is started, where the timing function is used to time the first touch duration of the target color film key.

[0115] When it is detected that the target color film button is triggered, that is, when it is detected that the user presses the target color film button, the first control component can time the first touch duration of the target color film button.

[0116] S702: When the target color film button is released from touch, determine a first touch duration.

[0117] S703: Generate first information according to the first touch duration and the first identifier of the target color film key.

[0118] After determining the duration for which the target color film key is pressed by the user, the second control component may generate first information according to the first touch duration and the first identifier of the target color film key.

[0119] Specifically, the second control component can determine the first state of the target color film key according to the first touch duration, the first state is a long press state or a short press state, and then generate the first information according to the first state and the first identifier. Exemplarily, the preset duration can be 3 seconds. When the first touch duration is less than 3 seconds, the first state can be determined to be a short press state. If the first touch duration is more than 3 seconds, the first state can be determined to be a long press state.

[0120] In this embodiment, when the second control component detects that the target color film key is triggered, it starts the timing function, and the timing function is used to time the first touch duration of the target color film key. Then, when the target color film 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 color film key, so as to realize the control of the corresponding function of the extended key through the second control component.

[0121] After the user unlocks the display module, if the user does not operate for a long time, the second control component can control the light-emitting component and the display screen to turn off to save power.

[0122] Specifically, Figure 8 A flow chart of another method for controlling a display module of a refrigerator provided in an embodiment of the present application is shown as follows: Figure 8 As shown, the method can be executed by a second control component, and the method can include the following steps:

[0123] S801. Within the first preset time after the first state of the display module is switched from the locked screen state to the unlocked state, or within the first preset time after the target color film button is triggered, if multiple color film buttons and multiple touch buttons are not detected to be triggered, send lock screen indication information to the first control component.

[0124] Within the first preset time after the first state of the display module is switched from the locked screen state to the unlocked state, or within the first preset time after the user presses the target color film button and lifts it, if multiple color film buttons and multiple touch buttons are not detected to be triggered, it means that the user has no operation within the first preset time, and the lock screen indication information can be sent to the first control component. The lock screen indication information is used to indicate that the first state of the display module is the locked screen state, and the first control component can set the first state of the display module to the locked screen state, that is, lock the display module, and the display screen can display the lock screen related interface.

[0125] Exemplarily, the first preset duration may be 30 seconds.

[0126] S802: Control the brightness value of the light-emitting component to be a preset brightness value.

[0127] The second control component can control the brightness of the light-emitting component to decrease, for example, the brightness value of the light-emitting component can be controlled to be a preset brightness value, which is smaller than the brightness of the light-emitting component when the display module is in an unlocked state.

[0128] It can be understood that in order to achieve synchronization of the display module entering the lock screen state and the brightness reduction of the light-emitting component, the second control component can control the brightness value of the light-emitting component to a preset brightness value after sending the lock screen indication information for a preset time. The preset time can be the time required for the first control component to send information to the second control component. Of course, since the preset time is short and can be ignored, the second control component can control the brightness of the light-emitting component to the preset brightness value when sending the lock screen indication information.

[0129] In this embodiment, within the first preset time after the first state of the display module is switched from the locked screen state to the unlocked state, or within the first preset time after the target color film button is triggered, if multiple color film buttons and multiple touch buttons are not detected to be triggered, the lock screen indication information is sent to the first control component, and the brightness value of the light emitting component is controlled to be a preset brightness value, so that the user can reduce the brightness of the light emitting component and lock the display module when there is no operation.

[0130] After the first state of the display module is switched to the locked screen state, that is, after the display module is locked, if the user does not operate for a long time, the light-emitting component and the display screen can be controlled to turn off to further save power.

[0131] Specifically, Fig. 9 A flow chart of another method for controlling a display module of a refrigerator provided in an embodiment of the present application is shown as follows: Fig. 9 As shown, the method can be executed by a second control component, and the method can include the following steps:

[0132] S901. Within a second preset time after the first state of the display module is switched to the lock screen state, if the multiple touch keys are not triggered and the multiple color film keys are not detected to be triggered, the second state of the light-emitting component is controlled to be off.

[0133] Within the second preset time after the display module switches from the first state to the lock screen state, if multiple touch buttons are not triggered and multiple color film buttons are not detected to be triggered, it means that the user still has no operation within the second preset time after the display module is locked, then the second control combination can control the light-emitting component to turn off.

[0134] Exemplarily, the second preset duration may be 1 minute.

[0135] S902: Determine that the second state of the display screen is off, and send control information to the first control component, where the control information is used to indicate that the second state of the display screen is off.

[0136] The second control component can determine that the second state of the display screen is off, and then send control information to the first control component. Exemplarily, the second state in the control information can be represented by 0, so that after receiving the control information, the first control component controls the second state of the display screen to off.

[0137] In this embodiment, if the user still does not perform any operation within the second preset time period after the display module enters the lock screen state, the light-emitting component and the display screen can be controlled to turn off.

Fig.10 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 control a signal to the main control board 106, so that the main control board 106 activates the corresponding function of the target color film button in a long press state or a short press state or the corresponding function of the target touch button (any one of the multiple touch buttons) in a long press state or a short press state in response to the control signal. For example, the target color film button is an unlock button, which can be unlocked in a long press state, and remains locked in a short press state, that is, not unlocked.
