[0042] 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 systems and methods consistent with some aspects of the present application as detailed in the claims.

[0043] A refrigerator is a refrigeration device that keeps a constant low temperature. It is also a product that keeps food or other items at a constant low temperature. The box contains a compressor, an ice maker, a cabinet or box for ice making, and a storage box with a refrigeration device. The capacity of a household refrigerator is usually 20 to 500 liters.

[0044] A compartment light is usually installed in the refrigerator compartment. The main purpose of the compartment light is to facilitate users to check the food inside the refrigerator. When the refrigerator door is opened, the light will automatically light up, so that users can clearly see the food inside the refrigerator and choose the items they need. However, the brightness of the refrigerator compartment light is constant. It is more suitable to take refrigerator photos when the outside is bright during the day. However, when the refrigerator door is opened at night with the lights off, the light is too bright and dazzles the eyes.

[0045] In the prior art, an ambient light sensor can be set up to be connected to the refrigerator controller to transmit external ambient light information to the refrigerator controller in real time. The controller adjusts the light brightness according to the received information. However, setting up an ambient light sensor requires additional circuit and software support, which increases the technical complexity and manufacturing cost of the refrigerator. At the same time, it is necessary to reserve a specific position to install the sensor, which affects the adjustment of the internal structure of the refrigerator and further increases the difficulty of design and production.

[0046] To solve the problem that the brightness of the refrigerator compartment light cannot change according to the ambient brightness, see Figure 1 Some embodiments of the present application provide a method for automatically adjusting refrigerator lighting, including:

[0047] S100: Control the WIFI module to send the IP address to the cloud server.

[0048] Among them, controlling the WIFI module to generate an IP address to the cloud server includes connecting to the WIFI network, obtaining the IP address of the device, configuring HTTP requests, sending data to the cloud server, and processing server responses.

[0049] Specifically, the WiFi module needs to be connected to the specified WiFi network first to ensure that the device is successfully connected to the network and obtains the IP address. Then the IP address of the current WiFi network is obtained through the programming interface or command.

[0050] When sending the IP address to the cloud server, you also need to set the URL, method, and necessary header information of the HTTP request before you can send the obtained IP address to the cloud server as part of the request body.

[0051] When using the HTTP client library to send a data packet containing an IP address to the cloud server, you need to ensure that the data packet format meets the requirements of the cloud server, such as the JSON format. After the cloud server receives the data packet containing the IP address, the cloud server receives and generates a server response, and sends the cloud server response to the controller to confirm whether the IP address is sent successfully. For example, when the cloud server successfully receives the data packet containing the IP address and parses the IP address from the data packet, it can generate a confirmation message and send it to the controller to confirm that the IP address is sent successfully. When the IP address is not parsed from the data packet, an error message can be generated and sent to the controller to prompt that the IP address is sent incorrectly.

[0052] S200: Obtaining lighting adjustment rules generated by the cloud server according to the IP address.

[0053] When the cloud server obtains the IP address of the WIFI network to which the WIFI module is connected, it can generate corresponding lighting adjustment rules according to the IP address, such as Figure 2 As shown, obtaining the lighting adjustment rules generated by the cloud server based on the IP address includes:

[0054] S210: Acquire the region information recorded in the IP address.

[0055] After the cloud server obtains the IP address, it can use the IP address query service, such as the IPGeolocation API, to obtain the region information corresponding to the IP address. The region information includes detailed geographic information such as country, province, and city.

[0056] S220: Obtaining time zone information corresponding to the regional information according to the regional information.

[0057] S230: Generate lighting adjustment rules according to the time zone information.

[0058] Due to the different time zones in different regions, the local ambient light intensity is different at the same time point. For example, at 7 o'clock in the evening, the ambient light intensity outside Liaoning is low, while the ambient light intensity outside Xinjiang is high, that is, the lighting adjustment rules in different regions are different. Therefore, after obtaining the regional information, it is necessary to obtain the corresponding time zone information through the regional information, and then generate the lighting adjustment rules through the time zone information. Among them, the time zone information can be queried through the time zone database or API to obtain the time zone information of the region.

[0059] In some embodiments, generating a lighting adjustment rule according to the time zone information includes:

[0060] According to the time zone information, obtain the sunrise time and sunset time corresponding to the time zone information.

[0061] Based on the sunrise time and sunset time, generate light intensity levels corresponding to several time points.

[0062] After obtaining the time zone information, the sunrise and sunset APIs can be used to extract specific sunrise and sunset times from the data returned by the sunrise and sunset APIs. For example, by inputting the time zone information in the Sunrise Sunset API, two data "06:45AM" and "07:15PM" are obtained in the returned data, where 06:45AM is the sunrise time and 07:15PM is the sunset time.

[0063] After obtaining the sunrise and sunset times, define the light intensity levels for different time periods according to the needs. For example, a day can be divided into several time periods, and each time period corresponds to a light intensity level.

[0064] For example, the light intensity level is set to 1-10, where the refrigerator compartment light level is 1, the light intensity of the refrigerator compartment light is the lowest, and the refrigerator compartment light level is 10, the light intensity of the refrigerator compartment light is the highest. During the interval from sunrise to sunset, the ambient light intensity will gradually increase, and when the ambient light intensity reaches the highest point, the ambient light intensity will gradually decrease, that is, from sunrise to sunset, the light intensity level increases from level 5 to level 10 and then decreases to level 5, and from sunset to sunrise, the light intensity level decreases from level 5 to level 1 and then increases to level 5. Specifically, when the sunrise time is 7 o'clock, the light intensity level is adjusted every hour, then the light intensity level corresponding to 7 o'clock-8 o'clock is level 5, the light intensity corresponding to 8 o'clock-9 o'clock is level 6, the light intensity corresponding to 12 o'clock-13 o'clock is level 10, and the light intensity corresponding to 13 o'clock-14 o'clock is level 9, and so on. The light intensity level corresponding to the time point can be generated through the sunrise time and sunset time. When the refrigerator door is opened, the refrigerator compartment light can directly work at the corresponding light intensity level, that is, the cloud server sends information when the light brightness needs to change. After receiving the information, the controller controls the light intensity level of the refrigerator compartment light. After the refrigerator door is opened, it can directly work at the current light intensity level.

[0065] S300: Generate a control instruction according to the light adjustment rule to control the brightness of the refrigerator compartment light.

[0066] Among them, according to the light adjustment rules, generating control instructions to control the brightness of the refrigerator compartment light specifically includes:

[0067] Get the light intensity level corresponding to the opening time of the refrigerator door.

[0068] According to the light intensity level, the refrigerator compartment light is controlled to operate at the light intensity level.

[0069] After the cloud server generates the light adjustment rules according to the IP address, the level of the refrigerator compartment light can be controlled according to the light adjustment rules, that is, the brightness of the refrigerator compartment light can be controlled.

[0070] Among them, after obtaining the light adjustment rule, when the refrigerator door is closed, the refrigerator compartment light is off, and when the refrigerator door is opened, the refrigerator compartment light is on. Therefore, it is necessary to obtain the opening time point of the refrigerator door. The opening time point of the refrigerator door can be obtained by monitoring the opening and closing status of the refrigerator door, for example, by monitoring the opening and closing status of the refrigerator door through a contact switch.

[0071] Specifically, after obtaining the light adjustment rules, when the refrigerator door is closed, the refrigerator compartment light is off, and when the refrigerator door is opened, the refrigerator compartment light is on. Therefore, it is necessary to obtain the opening time point of the refrigerator door. The opening time point of the refrigerator door can be obtained by monitoring the opening and closing of the refrigerator door, for example, by monitoring the opening and closing of the refrigerator door through a contact switch. Among them, the contact switch is a commonly used sensor that can detect the position or state change of an object through physical contact. In refrigerator applications, the contact switch can be installed on the refrigerator door. When the refrigerator door is closed, the contact switch is in the disconnected state; when the refrigerator door is opened, the contact switch is in the connected state.

[0072] Through the state change of the contact switch, the opening and closing of the refrigerator door can be monitored in real time, and the opening time of the refrigerator door can be obtained. Then the brightness of the refrigerator compartment light can be controlled according to the light adjustment rules. For example, when the refrigerator door is closed, the electric contact switch is disconnected and the refrigerator compartment light is automatically turned off; when the refrigerator door is opened, the contact switch is connected, and the controller adjusts the refrigerator compartment light to the corresponding brightness level according to the light adjustment rules.

[0073] For example, the current time is 12:59, and the light adjustment rule is to set the light intensity level to level 10. When the refrigerator door is opened, the contact switch is turned on, and the refrigerator compartment light directly works at the light intensity level 10. When the time passes a few minutes later and becomes 13:01, the light adjustment rule is to set the light intensity level to level 9, and the refrigerator compartment light can be controlled to work at the light intensity level 9.

[0074] In some embodiments, the refrigerator light automatic adjustment method further includes:

[0075] The working time period of the refrigerator is determined based on the sunrise time and the sunset time; the working time period includes the day time period and the night time period.

[0076] When the refrigerator is in the daytime period, a first light adjustment instruction is generated, and the first light adjustment instruction is used to control the refrigerator compartment light to operate with natural light.

[0077] When the refrigerator is in the night time period, a second light adjustment instruction is generated, and the second light adjustment instruction is used to control the refrigerator compartment light to operate in a warm light mode.

[0078] Among them, the daytime period starts from sunrise to sunset, and the nighttime period starts from sunset to sunrise the next day. For example, if the sunrise time is 06:30AM and the sunset time is 06:30PM, then the daytime period is: 06:30AM-06:30PM, and the nighttime period is 06:30PM-06:30AM (the next day). During the daytime period, the controller will generate a first light adjustment instruction to control the refrigerator compartment light to operate in natural light mode to simulate natural light during the day. For example, the light color temperature of the refrigerator compartment light is adjusted to a higher value to make the light closer to natural light. During the nighttime period, the controller will generate a second light adjustment instruction to control the refrigerator compartment light to operate in warm light mode to provide soft lighting and avoid interference with sleep. For example, the light color temperature of the refrigerator compartment light is adjusted to a lower value to make the light warmer and softer.

[0079] In some embodiments, the refrigerator light automatic adjustment method further includes:

[0080] Get the operating status of home lights stored in the cloud server.

[0081] If the refrigerator is in the night time period and the household light is in the on state, a third light adjustment instruction is generated, and the third adjustment instruction is used to control the refrigerator compartment light to operate at a preset light intensity level.

[0082] Specifically, when the home light is connected to the smart home, the cloud server can obtain the operating status of the home light in real time through integration with the smart home system. This includes whether the home light is turned on. If the refrigerator is in the night time period and the home light is turned on, it means that the environment in which the refrigerator is located is bright. Therefore, the controller will generate a third light adjustment instruction to control the refrigerator compartment light to operate at a preset intensity level. The preset light intensity level is a pre-set light intensity level.

[0083] For example, when the user opens the refrigerator door to take out a drink at 2 a.m. and the home light is off, the refrigerator compartment light is turned on at light intensity level 3. When the user opens the refrigerator door to take out a drink at 2 a.m. and the home light is on, the refrigerator compartment light is turned on at light intensity level 8.

[0084] In some embodiments, Figure 3As shown, the embodiment of the present application provides a refrigerator light automatic adjustment system, which is applied to the refrigerator light automatic adjustment method provided in the above embodiment, including:

[0085] Refrigerator compartment lights, WIFI modules, cloud servers, controllers.

[0086] Compartment lights are installed in the refrigerator and / or freezer.

[0087] The controller is connected with the WIFI module and the refrigerator compartment light.

[0088] The cloud server is connected to the controller via the WIFI module.

[0089] Among them, the WIFI module is mainly used to connect to the WIFI network to realize the function of data transmission, and the refrigerator compartment light is installed inside the refrigerator compartment for lighting. The cloud server is used to obtain the data transmitted by the WIFI module, process the data transmitted by the WIFI module, and then send the processed data to the WIFI module.

[0090] The controller is configured as:

[0091] Control the WIFI module to send the IP address to the cloud server.

[0092] Get the lighting adjustment rules generated by the cloud server based on the IP address.

[0093] According to the lighting adjustment rules, control instructions are generated to control the brightness of the refrigerator compartment light.

[0094] In some embodiments, the refrigerator light automatic adjustment system further includes a contact switch; the contact switch is respectively connected to the WIFI module and the refrigerator compartment light.

[0095] Among them, the contact switch is used to control the opening or closing of the refrigerator compartment light. When the refrigerator door is closed, the contact switch is disconnected and the refrigerator compartment light is turned off. When the refrigerator door is opened, the contact switch is closed and the refrigerator compartment light is turned on.

[0096] It can be seen from the above technical solutions that the present application provides a method and system for automatically adjusting the light of a refrigerator, the method comprising: controlling the WIFI module to send an IP address to a cloud server; obtaining a light adjustment rule generated by the cloud server according to the IP address; generating a control instruction according to the light adjustment rule to control the brightness of the refrigerator compartment light. When the refrigerator door is opened, the geographical location of the refrigerator and the time can be obtained through the IP address uploaded by the WIFI module to automatically adjust the brightness of the refrigerator compartment light. When the user turns on the refrigerator compartment light at night, the brightness is appropriate and will not dazzle the eyes. While improving the user experience, the energy consumption of the refrigerator can be reduced, and the waste of resources caused by the excessive light when the refrigerator door is opened can be reduced, so as to solve the problem that the brightness of the refrigerator compartment light cannot change according to the ambient brightness.
