[0018] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of devices and methods consistent with some aspects of the present application as detailed in the claims.

[0019] When developing the control panel of a smart refrigerator product, it is necessary to define the functions of the control panel according to the functions of the product. Since both hardware and software are involved, it is necessary to wait until the hardware processing of the control panel is completed before software development can be carried out, and then joint debugging and testing with the APP or mini program are carried out, which prolongs the production cycle of the control panel and thus the production cycle of the refrigerator product.

[0020] In order to solve the problem of long production cycle of control panel, some embodiments of the present application provide a programmable control device, see Figure 1 , Figure 1 The schematic diagram of the structure of the programmable control device provided for the present application includes: a control panel, a programmable control unit and a power supply unit; wherein the output end of the power supply unit is electrically connected to the input end of the control panel and the input end of the programmable control unit respectively, and the power supply unit is used to supply power to the control panel and the programmable control unit.

[0021] See also Figure 2 , Figure 2 The schematic diagram of the structure of the programmable control unit provided in the embodiment of the present application is used to configure the functions and display of the control panel, and the programmable control unit includes a function configuration circuit, a display configuration circuit, an interaction configuration circuit, a protocol configuration circuit and a configuration download circuit. The output end of the function configuration circuit, the output end of the display configuration circuit, the output end of the interaction configuration circuit, and the output end of the protocol configuration circuit are electrically connected to the input end of the configuration download circuit respectively.

[0022] The function configuration circuit is used to configure the control function and mode of the product. Developers can configure the control function and mode of the product by programming the control chip in the function configuration circuit. The function configuration circuit includes a switch subcircuit, a temperature adjustment subcircuit and a mode selection subcircuit. The output end of the switch subcircuit is electrically connected to the input end of the temperature adjustment subcircuit and the input end of the mode selection subcircuit respectively, and the output end of the mode selection subcircuit is electrically connected to the input end of the temperature adjustment subcircuit. By setting the switch subcircuit, the temperature adjustment subcircuit and the mode selection subcircuit, developers can configure the switch function, temperature adjustment function and various functional modes of the product through programming.

[0023] Taking refrigerator products as an example, the functional mode of the refrigerator product can be configured through the mode selection subcircuit. For example, the functional mode may include smart mode, quick freezing mode, refrigeration mode, and freezing mode. The switch state of the refrigerator product can be configured through the switch subcircuit. For example, two physical buttons can be defined to turn on or off the refrigerator product, or other physical buttons can be defined to turn on or off the above functional modes. The current mode state can be set by 0 or 1, for example, 0 means off and 1 means on. The temperature of each functional mode can be adjusted by the temperature adjustment subcircuit. For example, the temperature adjustment range of the refrigeration mode can be set to 2 to 8°C, and the temperature adjustment range of the freezing mode can be set to -24 to -16°C. At the same time, the temperature adjustment is set to increase by 1°C each time and cycle within the set range.

[0024] The display configuration circuit is used to configure the display of the product's functions or modes, etc. Developers can configure the display of the product's functions or modes, etc. by programming the control chip in the display configuration circuit. The display panel of a smart refrigerator product usually displays the product's functions or modes, etc. For example, the display panel will display words such as the refrigerator product's smart mode or quick freezing mode, and the display configuration circuit can configure the display content.

[0025] The interactive configuration circuit is used to configure the operation of triggering the function or mode of the product. Developers can configure the triggering operation of the product by programming the control chip in the interactive configuration circuit. For example, the operation of triggering different functions of the product can be a single button click, a double button click, or a long press.

[0026] The protocol configuration circuit is used to configure the communication protocol between the control panel and the external device. The developer can configure the communication protocol between the control panel and the external device by programming the control chip in the protocol configuration circuit. It is understandable that when controlling the refrigerator product through an external device such as an APP or applet in a mobile phone terminal, the external device needs to be connected to the refrigerator product in communication. In some embodiments, the external device can be connected to the control panel in communication, and the protocol configuration circuit can configure the communication protocol of the communication connection. It should be noted that when configuring the communication protocol, the position and parsing method of the product function or mode in the protocol should be determined.

[0027] The configuration download circuit is used to transmit the configured data information to the control panel. By connecting the input end of the configuration download circuit to the output end of the function configuration circuit, display configuration circuit, interaction configuration circuit, and protocol configuration circuit respectively, the data information in each circuit can be received.

[0028] In some embodiments, the programmable control unit further includes a storage circuit, the input end of the storage circuit is electrically connected to the output end of the function configuration circuit, the output end of the display configuration circuit, the output end of the interaction configuration circuit, and the output end of the protocol configuration circuit. The storage circuit can store the configuration data of the function configuration circuit, the display configuration circuit, the interaction configuration circuit, and the protocol configuration circuit to prevent data loss after a circuit failure.

[0029] See also Figure 3 , Figure 3 The control panel structure diagram provided for the embodiment of the present application, the control panel includes a communication port, a main control circuit, a communication circuit, a function key and a display panel. The communication port, the input end of the main control circuit, the input end of the communication circuit, the function key and the display panel are electrically connected to the output end of the power supply unit respectively. The communication port is connected to the output end of the configuration download circuit so that the communication port can receive the data information in the configuration download circuit. The input end of the main control circuit is electrically connected to the communication port, the main control circuit is used to receive the data information downloaded by the communication port, and the output end of the main control circuit is electrically connected to the function key and the display panel respectively to control the function of the function key and the display of the display panel according to the received data information. In some embodiments, the communication port can be an RS232 communication port, the function key can be multiple, and the specific number can be set according to the function or mode configured by the function configuration circuit, and the display panel can be an LED display screen. The output end of the main control circuit is also electrically connected to the input end of the communication circuit, and the communication circuit is connected to the external device through a communication protocol. The external device is the APP or applet in the mobile terminal described in the above embodiment.

[0030] The main control circuit includes a function subcircuit, a display subcircuit, an interaction subcircuit and a protocol subcircuit. The input ends of the function subcircuit, the display subcircuit, the interaction subcircuit and the protocol subcircuit are electrically connected to the communication port respectively. The function keys are electrically connected to the output ends of the function subcircuit and the output end of the interaction subcircuit respectively. The function subcircuit controls the function of the function key according to the received data information, and the interaction subcircuit controls the operation of the function key according to the received data information. The output end of the function subcircuit is also electrically connected to the input end of the display subcircuit, and the output end of the display subcircuit is electrically connected to the display panel, so that the display panel can display the function configured by the function key.

[0031] The output end of the protocol subcircuit is electrically connected to the input end of the communication circuit, so that the communication circuit can receive the communication protocol information of the protocol subcircuit and communicate with the external device according to the communication protocol information. The communication protocol includes a command header code, a command type, a command length and a verification method. The command header code is used to define the transmission direction of the command. The communication circuit can receive the command type sent by the external device and reply to the command type. The command type received by the communication circuit may include a status query command, a mode setting command, and a temperature setting command. The command type replied by the communication circuit is a full status reporting command. The communication mechanism between the communication circuit and the external device is: after the control panel receives the command sent by the external device, it first performs a verification. If the verification is wrong, the frame data is ignored and the next frame data is continued to be received; if the verification is correct, the received command type is analyzed and processed accordingly.

[0032] It is understandable that the control panel in the embodiment of the present application does not need to be a control panel with a complete finished product structure, and can be composed by piecing together multiple hardware components, as long as the control function of the control panel can be realized. For example, the communication port, the main control circuit and the communication circuit can be integrated on a control panel, and a number of function buttons and a display panel electrically connected to the main control circuit are set at the same time. After the programmable control unit is connected to the communication port through a data line, it is connected to the external device through the communication circuit, and the control panel, refrigerator product and external device can be tested for joint debugging. By pre-configuring the function or mode on the programmable control unit, and then transmitting the configuration setting to the control panel, there is no need to edit the program on the completed control panel, and joint debugging and testing can be performed with the external device, which saves the time required for the program editing process and shortens the production and development cycle of the control panel.

[0033] See again Figure 1 In some embodiments, the power supply unit includes a DC conversion circuit, and the output end of the DC conversion circuit is electrically connected to the input end of the function configuration circuit, the input end of the display configuration circuit, the input end of the interaction configuration circuit, the input end of the protocol configuration circuit, the input end of the storage circuit, the input end of the main control circuit, and the input end of the communication circuit. The DC conversion circuit can convert the output voltage of the power supply unit into the operating voltage of each of the above-mentioned circuits so that each circuit can work normally.

[0034] Some embodiments of the present application also provide a refrigerator, including a box body, a door body and a programmable control device provided in some of the above embodiments, the box body is hinged to the door body, the device includes a control panel, a programmable control unit and a power supply unit, the control panel is arranged on the door body, and the control panel is detachably connected to the door body. It should be noted that the control panel connected to the door body can be a control panel of a finished structure with pre-configured functions or modes provided in the above embodiments. Since the control panel and the programmable control unit are connected through a communication port, the programmable control unit can be removed after the refrigerator product is debugged.

[0035] It can be seen from the above technical scheme that the embodiment of the present application provides a programmable control device and a refrigerator, the device includes a control panel, a programmable control unit and a power supply unit, and the power supply unit is electrically connected to the control panel and the programmable control unit respectively. The programmable control unit includes a function configuration circuit, a display configuration circuit, an interactive configuration circuit, a protocol configuration circuit and a configuration download circuit. The function configuration circuit, the display configuration circuit, the interactive configuration circuit, and the protocol configuration circuit are respectively used to configure the function mode, function display, key operation and communication protocol of the control panel, and the configuration download circuit is used to transmit the above configuration data to the control panel so that the control panel controls the function buttons and the display panel according to the received data information, and the control panel is connected to the external device through the configured communication protocol communication.
