Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] The terms "first", "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0057] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0058] See also Figure 1 , Figure 1 It is a schematic diagram of the external structure of a refrigerator provided by an embodiment of the present invention. The refrigerator 100 of this embodiment is approximately in the shape of a rectangular parallelepiped. The refrigerator includes a box body that defines a storage space and a plurality of door bodies arranged at the opening of the box body, wherein the door body includes a door body shell located on the outside of the box body, a door body liner located on the inside of the box body, an upper end cover, a lower end cover, and an insulating layer located between the door body shell, the door body liner, the upper end cover, and the lower end cover; usually, the insulating layer is filled with foam. The box body is provided with a chamber, wherein the chamber includes a component storage chamber for placing components in the refrigerator, such as a press cabin, etc., and also includes a storage space for storing food, etc. The refrigerator also includes a display panel 101, which is located on the door of the box and is used to display the operation information of the refrigerator and receive user input operations. The display panel is provided with a number of buttons.

[0059] See also Figure 2 , Figure 2 : is a schematic diagram of the internal structure of a refrigerator provided by an embodiment of the present invention. The storage space can be divided into multiple storage rooms. The storage rooms can be configured as refrigerators and freezers according to different uses. They can also include variable temperature rooms, vacuum drawers, moisturizing drawers, etc. Each storage room corresponds to one or more door bodies, for example, Figure 2 The storage room at the upper part is provided with a double-opening door body. The door body can be pivotally arranged at the opening of the box body, and can also be opened in a drawer-like manner to realize drawer-like storage.

[0060] See also Figure 3 , Figure 3 It is a structural schematic diagram of the refrigeration system in the refrigerator provided by an embodiment of the present invention, and the refrigeration system includes a compressor 1, an evaporator 2, a drying filter (not shown in the figure), a capillary tube 3, a condenser 4 and a gas-liquid separator (not shown in the figure). The working process of the refrigeration system includes a compression process, a condensation process, a throttling process and an evaporation process. Among them, the compression process is: plug in the power cord of the refrigerator, when the contacts of the thermostat are connected, the compressor 1 starts to work, and the low-temperature and low-pressure refrigerant is sucked into the compressor 1, and is compressed into a high-temperature and high-pressure superheated gas in the cylinder of the compressor 1 and then discharged to the condenser 4; the condensation process is: the high-temperature and high-pressure refrigerant gas dissipates heat through the condenser 4, the temperature continues to drop, and is gradually cooled to a saturated vapor of normal temperature and high pressure, and is further cooled to a saturated liquid, and the temperature no longer drops. The temperature at this time is called the condensation temperature, and the pressure of the refrigerant remains almost unchanged during the entire condensation process; the throttling process is as follows: The flow process is as follows: the saturated liquid refrigerant after condensation is filtered out of moisture and impurities by a drying filter and then flows into the capillary tube 3 for throttling and pressure reduction, and the refrigerant becomes wet steam at room temperature and low pressure; the evaporation process is as follows: the wet steam at room temperature and low pressure begins to absorb heat and vaporize in the evaporator 2, which not only reduces the temperature of the evaporator 2 and its surroundings, but also turns the refrigerant into a low-temperature and low-pressure gas. The refrigerant coming out of the evaporator 2 passes through the gas-liquid separator and then returns to the compressor 1, repeating the above process to transfer the heat in the refrigerator to the air outside the box, thereby achieving the purpose of refrigeration.

[0061] See also Figure 4 , Figure 4 It is a schematic diagram of a display panel in a refrigerator provided by an embodiment of the present invention, wherein the display panel 101 includes a plurality of buttons 102 and a display 103. The display panel is integrated on a display module, and the model of the display module is HX-HB6865. The touch button control part of the display panel of this scheme is mainly composed of a display module (containing a touch spring button and a digital tube) and a dedicated CPU chip (with a touch sensing function, which can process the touch button signal and determine whether the button is pressed). The display module is also connected to a display driver chip, and the model of this display driver chip is MC2204. The CPU drives the display driver chip through pins to achieve the effect of controlling the display panel. The buttons of the display module are directly connected to the pins of the CPU with TK function. The pin schematics and connection relationships of the specific CPU chip, display module chip and display driver chip can refer to the existing digital tube drive circuit, which will not be repeated here.

[0062] Specifically, the controller described in the embodiment of the present invention is configured as follows: when the refrigerator is operating in the normal button operation mode, if a long press operation of a designated button is detected, the button sensitivity adjustment mode is entered; when a short press operation of any button is detected, the corresponding button sensitivity adjustment operation is performed according to the number of short press operations; when a long press operation of the designated button is detected, the sensitivity adjustment mode is exited and the normal button operation mode is entered.

[0063] For example, see Figure 5 , Figure 5 It is the first working flow chart of the controller provided by the embodiment of the present invention, and the controller is configured to execute steps S11 to S18. When the refrigerator is running in the normal working mode of the key, the key on the display panel performs the corresponding function. If it is detected that the user long presses the designated key on the display panel, the key sensitivity adjustment mode is entered. At this time, the key no longer performs the original function, but is used to adjust the sensitivity; the designated key is used to enter and exit the key sensitivity adjustment mode. In the key sensitivity adjustment mode, the sensitivity level is modified by short pressing the key. If it is detected that the user short presses any key, the corresponding key sensitivity adjustment operation is performed according to the number of short press operations. When the adjustment operation is completed, the designated key can be long pressed to exit the sensitivity adjustment mode. If it is detected that the user long presses the designated key, the sensitivity adjustment mode is exited and the normal working mode of the key is entered. At this time, the key resumes to perform the original function. Among them, the number of the keys can be one or more, and the number of seconds for long pressing the designated key is pre-set before leaving the factory, such as 3 to 5 seconds, or the number of seconds for long pressing can also be set by the user, which is not specifically limited here.

[0064] Specifically, the controller is also configured to: when a voltage signal on any key is detected, obtain the voltage signal; when the voltage signal reaches a preset voltage threshold corresponding to the current key, determine that the current key is pressed; when the voltage signal does not reach the voltage threshold, determine that the current key is not pressed.

[0065] For example, see Figure 6 , Figure 6It is the second working flow chart of the controller provided by the embodiment of the present invention, and the controller is also configured to execute steps S21 to S25. The controller also includes a signal processing chip, which has a touch sensing function and can process touch button signals to determine whether the button is pressed. Each button has a preset voltage threshold. When a voltage signal on any button is detected, the voltage signal is obtained and compared with the preset voltage threshold corresponding to the current button. When the voltage signal reaches the preset voltage threshold, it is determined that the current button is pressed. When the voltage signal does not reach the voltage threshold, it is determined that the current button is not pressed. Among them, the preset voltage thresholds of different buttons can be the same or different. The voltage thresholds of some special function buttons (such as child safety locks, refrigerator ice buttons, etc.) can be set larger to prevent children from accidentally touching them.

[0066] Specifically, performing corresponding key sensitivity adjustment operation according to the number of short press operations includes: obtaining the number of short press operations detected within a preset time period, and adjusting the sensitivity level of the current key according to the number of short press operations; wherein the number of key presses is proportional to the sensitivity level.

[0067] For example, see Figure 7 , Figure 7 is the third workflow diagram of the controller provided in an embodiment of the present invention, and the controller is further configured to execute steps S31 to S32. In the key sensitivity adjustment mode, the user modifies the sensitivity level by short pressing the key. If it is detected that the user performs a short press operation on any key, the number of short presses within a preset time period is obtained, and the sensitivity is adjusted to a corresponding level according to the number of short presses; wherein the number of key presses is proportional to the sensitivity level, and each time a key is short pressed, the sensitivity of the corresponding key increases by one level.

[0068] Specifically, adjusting the sensitivity level of the current key according to the number of key presses also includes: when the sensitivity level of the current key is the highest level, modifying the current sensitivity level to the lowest level, and modifying the preset voltage threshold to the voltage threshold corresponding to the lowest level; when the sensitivity level of the current key is not the highest level, modifying the current sensitivity level to the next sensitivity level, and modifying the preset voltage threshold to the voltage threshold corresponding to the next sensitivity level.

[0069] For example, see Figure 8 , Figure 8It is the fourth work flow chart of the controller provided by the embodiment of the present invention, and the controller is further configured to execute steps S41 to S45. After the user performs a short press operation in the key sensitivity adjustment mode, the number of short press operations and the sensitivity level of the current key within the preset time period are obtained, and it is determined whether the current sensitivity level is the highest sensitivity level. When the sensitivity level of the current key is the highest level, the user performs a short press operation, the current sensitivity level is modified to the lowest level, and the preset voltage threshold is modified to the voltage threshold corresponding to the lowest level. Then, a short press operation is performed again, and the sensitivity is increased by one level, and the preset voltage threshold is modified to the voltage threshold corresponding to the next sensitivity level; when the sensitivity level of the current key is not the highest level, a short press operation is performed, the current sensitivity level is modified to the next sensitivity level, and the preset voltage threshold is modified to the voltage threshold corresponding to the next sensitivity level. Specifically, different voltage thresholds can be set to form a threshold parameter set. Different sensitivity levels correspond to different voltage thresholds. a[1] corresponds to level 1 sensitivity, a[2] corresponds to level 2 sensitivity, a[3] corresponds to level 3 sensitivity, a[4] corresponds to level 4 sensitivity, a[5] corresponds to level 5 sensitivity, and so on. For example, the initial sensitivity level of a common function key can be set to level 3, and the preset voltage threshold corresponds to a[3]. The initial sensitivity level of a special function key can be set to level 5, and the preset voltage threshold corresponds to a[5], and so on.

[0070] Specifically, a display is also provided on the display panel; then, the controller is further configured to: in the key sensitivity adjustment mode, control the display to display the current sensitivity level of the corresponding key.

[0071] For example, see Fig. 9 , Fig. 9 is the fifth work flow chart of the controller provided in the embodiment of the present invention, and the controller is further configured to execute steps S51 to S53. A display is also provided on the display panel of the refrigerator. When the refrigerator is operated in the key sensitivity adjustment mode, the controller controls the display to display the current sensitivity level of the corresponding key. After the user performs a short press operation on the key, the display displays the modified sensitivity level of the corresponding key according to the number of short presses, so that the user can more intuitively understand the sensitivity level adjustment situation; when the refrigerator is operated in the normal working mode, the controller controls the display to display the current working temperature of the refrigerator.

[0072] Compared with the prior art, the refrigerator disclosed in the present invention enters a button sensitivity adjustment mode by long pressing a designated button, and adjusts the sensitivity level of the button by short pressing a corresponding button, so that the user can adjust the sensitivity of each function button on the refrigerator touch display panel by himself, thereby improving user convenience and reducing product after-sales maintenance costs.

[0073] See also Fig.10 , Fig.10 The flowchart of a method for adjusting the sensitivity of a key of a refrigerator provided by an embodiment of the present invention is a flowchart of a method for adjusting the sensitivity of a key of a refrigerator provided by an embodiment of the present invention. The method for controlling a refrigerator provided by an embodiment of the present invention is implemented by a controller in a refrigerator. The refrigerator includes a cabinet, a cabinet door, and a display panel. The display panel is provided on the cabinet door and is used to display the operation information of the refrigerator and receive the input operation of the user. The display panel includes a plurality of keys. Then, the method for adjusting the sensitivity of a key of a refrigerator includes:

[0074] S1. When the refrigerator is operating in the normal button operation mode, if a long press operation of a designated button is detected, the button sensitivity adjustment mode is entered;

[0075] S2. When a short press operation of any key is detected, a corresponding key sensitivity adjustment operation is performed according to the number of short press operations;

[0076] S3. When a long press operation of the designated key is detected, exit the sensitivity adjustment mode and enter the normal working mode of the key.

[0077] Exemplarily, when the refrigerator is operating in the normal button operation mode, the buttons on the display panel perform corresponding functions. If it is detected that the user long presses the designated button on the display panel, the refrigerator enters the button sensitivity adjustment mode. At this time, the button no longer performs the original function, but is used to adjust the sensitivity. The designated button is used to enter and exit the button sensitivity adjustment mode. In the button sensitivity adjustment mode, the sensitivity level is modified by short pressing the button. If it is detected that the user short presses any button, the corresponding button sensitivity adjustment operation is performed according to the number of short press operations. When the adjustment operation is completed, the designated button can be long pressed to exit the sensitivity adjustment mode. If it is detected that the user long presses the designated button, the sensitivity adjustment mode is exited and the normal button operation mode is entered. At this time, the button resumes to execute the original function. Among them, the number of the buttons can be one or more, and the number of seconds for long pressing the designated button is preset before leaving the factory, and is not specifically limited here.

[0078] Specifically, the method also includes: when a voltage signal on any key is detected, acquiring the voltage signal; when the voltage signal reaches a preset voltage threshold corresponding to the current key, determining that the current key is pressed; when the voltage signal does not reach the voltage threshold, determining that the current key is not pressed.

[0079] Exemplarily, the controller also includes a signal processing chip, which has a touch sensing function and can process touch button signals to determine whether the button is pressed. Each button has a preset voltage threshold. When a voltage signal on any button is detected, the voltage signal is obtained and compared with the preset voltage threshold corresponding to the current button. When the voltage signal reaches the preset voltage threshold, it is determined that the current button is pressed. When the voltage signal does not reach the voltage threshold, it is determined that the current button is not pressed. Among them, the preset voltage thresholds of different buttons can be the same or different. The voltage thresholds of some special function buttons (such as child safety locks, refrigerator ice buttons, etc.) can be set larger to prevent children from touching them by mistake.

[0080] Specifically, performing corresponding key sensitivity adjustment operation according to the number of short press operations includes: obtaining the number of short press operations detected within a preset time period; adjusting the sensitivity level of the current key according to the number of key presses; wherein the number of key presses is proportional to the sensitivity level.

[0081] Exemplarily, in the button sensitivity adjustment mode, the user modifies the sensitivity level by short pressing the button. If it is detected that the user short presses any button, the number of short presses within a preset time period is obtained, and the sensitivity is adjusted to the corresponding level according to the number of short presses; wherein, the number of button presses is directly proportional to the sensitivity level, and each time a button is short pressed, the sensitivity of the corresponding button increases by one level.

[0082] Specifically, adjusting the sensitivity level of the current key according to the number of key presses also includes: when the sensitivity level of the current key is the highest level, modifying the current sensitivity level to the lowest level, and modifying the preset voltage threshold to the voltage threshold corresponding to the lowest level; when the sensitivity level of the current key is not the highest level, modifying the current sensitivity level to the next sensitivity level, and modifying the preset voltage threshold to the voltage threshold corresponding to the next sensitivity level.

[0083] Exemplarily, after the user performs a short press operation in the button sensitivity adjustment mode, the number of short press operations on the button within a preset time period and the sensitivity level of the current button are obtained, and it is determined whether the current sensitivity level is the highest sensitivity level. When the sensitivity level of the current button is the highest level, the user performs a short press operation, the current sensitivity level is modified to the lowest level, and the preset voltage threshold is modified to the voltage threshold corresponding to the lowest level. Then, a short press operation is performed again, the sensitivity increases by one level, and the preset voltage threshold is modified to the voltage threshold corresponding to the next sensitivity level. When the sensitivity level of the current button is not the highest level, a short press operation is performed, the current sensitivity level is modified to the next sensitivity level, and the preset voltage threshold is modified to the voltage threshold corresponding to the next sensitivity level. Specifically, different voltage thresholds can be set to form a threshold parameter set. Different sensitivity levels correspond to different voltage thresholds. a[1] corresponds to level 1 sensitivity, a[2] corresponds to level 2 sensitivity, a[3] corresponds to level 3 sensitivity, a[4] corresponds to level 4 sensitivity, a[5] corresponds to level 5 sensitivity, and so on. For example, the initial sensitivity level of a common function key can be set to level 3, and the preset voltage threshold corresponds to a[3]. The initial sensitivity level of a special function key can be set to level 5, and the preset voltage threshold corresponds to a[5], and so on.

[0084] Specifically, a display is also provided on the display panel; then, the method further comprises: in the key sensitivity adjustment mode, controlling the display to display the current sensitivity level of the corresponding key.

[0085] Exemplarily, a display is also provided on the display panel of the refrigerator. When the refrigerator operates in a button sensitivity adjustment mode, the controller controls the display to display the current sensitivity level of the corresponding button. After the user short presses the button, the display displays the modified sensitivity level of the corresponding button according to the number of short presses, so that the user can understand the sensitivity level adjustment more intuitively; when the refrigerator operates in a normal working mode, the controller controls the display to display the current working temperature of the refrigerator.

[0086] Compared with the prior art, the refrigerator button sensitivity adjustment method disclosed in the present invention enters the button sensitivity adjustment mode by long pressing the designated button, and adjusts the sensitivity level of the button by short pressing the corresponding button, so that the user can adjust the sensitivity of each function button on the refrigerator touch display panel by himself, thereby improving user convenience and reducing product after-sales maintenance costs.

[0087] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
