[0058] The embodiments of the present application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0059] In the description of the present specification, the description of the terms "some embodiments", "in embodiments", "example", "specific example", or "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiments or examples are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiments or examples. Also, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples. In addition, the person skilled in the art can combine and combine the different embodiments or examples described in the present specification and the features of the different embodiments or examples without contradiction.

[0060] The sterilization method, device, refrigerator, equipment, medium and program product of the refrigerator according to the present application will be described below with reference to Figs. 1-7.

[0061] Fig. 1 is a first flowchart of the sterilization method of the refrigerator according to the present application, as shown in Fig. 1, the sterilization method of the refrigerator can be applied to the refrigerator, including but not limited to the following steps 101 and 102.

[0062] Step 101: determining that the standby time length of the pulse function module is greater than the first preset time length, and generating a sterilization signal.

[0063] The pulse function module is a function module connected to the refrigerator, which emits pulse light in the refrigerator to sterilize the food in the refrigerator.

[0064] The standby time length refers to the cumulative time length of the pulse function module in the standby state of non-sterilization.

[0065] The first preset time length is a time length between two sterilizations of the refrigerator.

[0066] Specifically, when the standby time length of the pulse function module exceeds the first preset time length, the controller automatically generates a sterilization signal to trigger the pulse function module to enter the sterilization state, indicating that the refrigerator has not been sterilized for a period of time and the user has not manually started the sterilization function within the first preset time length.

[0067] In an embodiment, the standby time length starts to be counted from when the refrigerator is powered on or from when the pulse function module completes the last sterilization.

[0068] Optionally, the pulse function module sends a sterilization termination signal to the refrigerator when it completes the last sterilization, and the refrigerator starts to count from when the sterilization termination signal is received.

[0069] Optionally, based on the working principle of the pulse function module sterilizing food by emitting pulse light, a light sensor can be arranged inside the refrigerator to sense the pulse light emitted by the pulse function module, and the controller starts to count from when the light sensor senses the last pulse light in the last sterilization process.

[0070] Optionally, based on the sterilization time determined according to the sterilization mode and the start time of the last sterilization, the controller starts to count from when the start time of the last sterilization has elapsed for the sterilization time.

[0071] In some embodiments, the first preset time length can be determined according to at least one of the following factors: the capacity and structure of the refrigerator, the type and / or actual storage of food in the refrigerator, the sterilization frequency, the food storage requirement, the real-time temperature in the refrigerator, the actual operation of the refrigerator, etc.

[0072] For example, the first preset time length is set to 8 hours, 12 hours, or 16 hours, etc.

[0073] Optionally, the first preset time length can be shortened or lengthened during the operation of the refrigerator based on factors such as the type and / or actual storage of food in the refrigerator, the completion of the last sterilization of the refrigerator, etc.

[0074] For example, the factory setting of the first preset time length is 12 hours, which can be lengthened to 16 hours when there is too much food stored in the refrigerator, or shortened to 8 hours when the user does not open the refrigerator door or add new food after the completion of the last sterilization of the refrigerator.

[0075] In an embodiment, the pulse function module includes a xenon lamp.

[0076] In an embodiment, the pulse function module and the refrigerator are detachably connected or non-detachably connected.

[0077] It should be noted that the pulse function module can be installed at any position of the refrigerator where sterilization of food is required, and can be installed on the refrigeration chamber or in a drawer of the refrigeration chamber; can be installed on the top wall of the refrigeration chamber or on the side wall of the refrigeration chamber. The specific installation position of the pulse function module can be determined according to the actual sterilization requirement, and the application does not limit this.

[0078] Step 102: Send the sterilization signal to the pulse function module, the sterilization signal being used to instruct the pulse function module to emit pulse light in the refrigerator according to the sterilization mode.

[0079] The sterilization mode includes but is not limited to at least one of the indicators consisting of the number of times, the frequency, the light intensity, and the single light duration of the pulse light emitted by the pulse function module in the refrigerator.

[0080] For example, the sterilization mode is that the pulse function module emits pulse light in the refrigerator at a frequency of 1 time per second for 180 seconds to sterilize the food.

[0081] For another example, the sterilization mode is that the pulse function module emits pulse light in the refrigerator at a frequency of 2 times per second for 90 seconds to sterilize the food.

[0082] Specifically, after generating the sterilization signal, the controller transmits the sterilization signal to the pulse function module, and triggers the pulse function module to emit pulse light in the refrigerator according to the preset sterilization mode after receiving the sterilization signal, so as to disinfect the food in the refrigerator.

[0083] For the refrigerator equipped with the pulse function module for realizing the sterilization function, the user often needs to manually turn on the sterilization function. And after completing the sterilization once, the user still needs to manually turn on the sterilization next time. That is, the user needs to manually turn on the sterilization function each time. In this case, many users will forget to turn on the sterilization function, or will not turn on the sterilization function because they think that it is too troublesome to manually turn on the sterilization each time, resulting in that the food in the refrigerator cannot be sterilized, bacteria breed, and the cleanliness of the food and the refrigerator is seriously affected.

[0084] The refrigerator sterilization method provided by the application counts the standby time length of the pulse function module, and automatically generates a sterilization signal for triggering the pulse function module to sterilize when the sterilization time length of the refrigerator exceeds the preset time length, so as to control the pulse function module to automatically sterilize in the refrigerator when the user forgets to sterilize or thinks that it is too troublesome to manually turn on the sterilization, prevent the food from breeding bacteria during refrigeration, and effectively ensure the cleanliness of the food and the refrigerator.

[0085] Based on the above embodiments, the sending of the sterilization signal to the pulse function module comprises:

[0086] determining that the refrigerator door of the refrigerator is in a closed state, and sending the sterilization signal to the pulse function module;

[0087] determining that the refrigerator door of the refrigerator is in an open state, and waiting for the refrigerator door to be in a closed state before sending the sterilization signal to the pulse function module.

[0088] Specifically, when the standby duration of the pulse function module exceeds the first preset duration, the controller generates a sterilization signal, but before sending the sterilization signal to the pulse function module, the controller first obtains a determination result of whether the refrigerator door is in a closed state, and determines the timing of sending the sterilization signal to the pulse function module according to the determination result.

[0089] If it is determined that the refrigerator door of the refrigerator is in a closed state, the sterilization signal can be directly sent to the pulse function module.

[0090] If it is determined that the refrigerator door of the refrigerator is in an open state, the sending of the sterilization signal to the pulse function module is paused, and the sterilization signal is sent to the pulse function module only after it is determined that the refrigerator door of the refrigerator is in a closed state, so as to trigger the pulse function module to emit pulse light in the refrigerator according to the sterilization mode.

[0091] Optionally, when it is determined that the refrigerator door of the refrigerator is in an open state, the controller receives a door closing signal generated by a light intensity sensor arranged inside the refrigerator when the light intensity sensor senses a sudden change in ambient light intensity.

[0092] When the refrigerator door is in an open state, ambient light can enter the inside of the refrigerator, and the lighting lamp inside the refrigerator is turned on. When the refrigerator door changes from an open state to a closed state, the refrigerator door blocks ambient light, and the lighting lamp inside the refrigerator is turned off. Therefore, the signal generated by the light intensity sensor when it senses a sudden change in ambient light intensity can be used as a door closing signal generated when the refrigerator door changes from an open state to a closed state.

[0093] Optionally, the door closing signal is a signal generated by a pressure sensor arranged at a door frame of the refrigerator door when the door frame changes from a pressure release state to a pressure state.

[0094] The refrigerator sterilization method provided in the present application determines whether the refrigerator door is in a closed state when the user does not manually turn on the sterilization function for a certain period of time, and triggers the pulse function module to perform sterilization only when it is confirmed that the refrigerator door is in a closed state, thereby avoiding the pulse light emitted by the pulse function module from irradiating the user who is using the refrigerator while opening the door, and preventing adverse effects on the user, and ensuring sterilization safety.

[0095] Based on the above embodiments, the determination that the refrigerator door of the refrigerator is in an open state, the sending of the sterilization signal to the pulse function module after waiting for the refrigerator door to be in a closed state, comprises:

[0096] determining that the refrigerator door of the refrigerator is in an open state, and generating a light-on signal;

[0097] sending the light-on signal to the indicator light, the light-on signal being used to instruct the indicator light to remain on.

[0098] Specifically, before the automatic start of the sterilization function is required, if it is determined that the refrigerator door is not closed, the controller generates a light-on signal and sends it to the indicator light. After the indicator light receives the light-on signal, it remains on to remind the user who is using the refrigerator that the sterilization function will be automatically started soon, and the user needs to use the refrigerator as soon as possible and close the refrigerator door.

[0099] Optionally, the light-on signal generated by the controller can also be sent to the pulse function module, and after the pulse function module receives the light-on signal, it is forwarded to the indicator light connected to the pulse function module.

[0100] Further, after the user closes the refrigerator door, the controller sends a door-closing signal to the pulse function module, and after the pulse function module receives the door-closing signal, it not only starts to emit pulsed light in the refrigerator, but also controls the indicator light to turn off from being on.

[0101] Optionally, the indicator light is integrally arranged on the pulse function module, and the pulse function module controls the indicator light to remain on after receiving the light-on signal.

[0102] Optionally, the indicator light is connected to the pulse function module by electrical connection, rather than being integrated in the pulse function module. At this time, the installation positions of the pulse function module and the indicator light can be different.

[0103] For example, the pulse function module is installed on the top wall inside the refrigerator, so that the emitted pulsed light is more likely to irradiate all the stored food materials. At the same time, the indicator light can be installed on the inner wall of the refrigerator opposite to the refrigerator door, which is more likely to attract the attention of the user, so as to better prompt the user that the sterilization function will be automatically started soon.

[0104] In another embodiment, the pulse function module is connected with an indicator voice playing device.

[0105] Before the automatic start of the sterilization function is required, if it is determined that the refrigerator door is not closed, the controller generates a playing signal and sends it to the pulse function module. After the pulse function module receives the playing signal, the indicator voice playing device connected to the pulse function module starts to work, and plays the pre-stored voice to the user that the sterilization function will be automatically started soon, so as to remind the user to use the refrigerator as soon as possible and close the refrigerator door.

[0106] The refrigerator sterilization method provided by the present application can provide the user with the need to use the refrigerator as soon as possible and close the refrigerator door, so as to safely sterilize the food after the user closes the refrigerator door, when the refrigerator is about to automatically start the sterilization function and the user is still using the refrigerator.

[0107] Based on the above embodiment, after the sterilization signal is sent to the pulse function module, the method further comprises:

[0108] determining that the refrigerator door of the refrigerator is in an open state, sending a pause sterilization signal to the pulse function module, the pause sterilization signal being used to instruct the pulse function module to pause emitting the pulsed light;

[0109] after the refrigerator door is in a closed state, sending a resume sterilization signal to the pulse function module, the resume sterilization signal being used to instruct the pulse function module to continue emitting the pulsed light according to the sterilization mode.

[0110] After the refrigerator starts the automatic sterilization function, it generally takes tens of seconds to several minutes to complete the sterilization of food. When the refrigerator is sterilizing with pulsed light and the sterilization is not completed, if the user opens the refrigerator door at this time, the pulsed light sterilization needs to be automatically paused.

[0111] Specifically, when the user opens the refrigerator door, the opening signal generated by the change of the refrigerator door from the closed state to the open state is sensed by the pressure sensor, the light sensor, the infrared sensor and the like, the controller generates a pause sterilization signal, and sends the pause sterilization signal to the pulse function module. After receiving the pause sterilization signal, the pulse function module pauses emitting the pulsed light.

[0112] Further, when the sterilization is paused, after the user closes the door again, the closing signal generated by the change of the refrigerator door from the open state to the closed state is obtained. The controller generates a resume sterilization signal, and sends the resume sterilization signal to the pulse function module. After receiving the resume sterilization signal, the pulse function module resumes emitting the pulsed light according to the sterilization mode.

[0113] For example, if the sterilization mode is that the pulse function module works continuously at a frequency of 1 time per second for 180 seconds. When the user opens the refrigerator door, the pulse function module has worked for 80 seconds, that is, has emitted 80 times of pulsed light. Then, after the user closes the door again, the pulse function module continues to work for 100 seconds, that is, still needs to emit 100 times of pulsed light.

[0114] The refrigerator is provided with an indicator light and / or an indication voice playing device. If the refrigerator door is suddenly opened by a user when the pulse function module emits pulse light to sterilize the food in the refrigerator, the control indicator light and / or the indication voice playing device perform the operation of keeping the indicator light on, playing the indication voice that the automatic sterilization is in progress, and the like, to prompt the user that the refrigerator is in automatic sterilization and the refrigerator door needs to be closed as soon as possible.

[0115] The refrigerator sterilization method provided in the application can automatically pause the sterilization when the refrigerator is in automatic sterilization and the refrigerator door is opened by a user, and then resume the sterilization after the user closes the door, so as to avoid that the pulse light emitted by the pulse function module irradiates the user who needs to open the door to use the refrigerator, and to protect the sterilization safety.

[0116] Based on the above embodiment, the sterilization mode comprises:

[0117] The pulse function module enters a working preparation state after receiving the sterilization signal or the sterilization resuming signal;

[0118] The pulse function module emits pulse light in the refrigerator after the time length of the pulse function module entering the working preparation state exceeds a second preset time length.

[0119] Specifically, the pulse function module does not emit pulse light immediately after receiving the sterilization signal or the sterilization resuming signal, but enters a working preparation state, and then emits pulse light in the refrigerator to sterilize the food after the time length of entering the working preparation state exceeds a second preset time length.

[0120] The second preset time length can be determined according to one or more of the performance parameters of the pulse function module, the capacity of the refrigerator, the types and quantities of the food stored in the refrigerator, and the like.

[0121] For example, the second preset time length can be set to 3 seconds, 4 seconds, 8 seconds, 10 seconds, and the like.

[0122] Compared with the method that the pulse function module sterilizes immediately by emitting pulse light after receiving the sterilization signal or the sterilization resuming signal, the sterilization mode provided in the application is that the pulse function module enters a working preparation state for a certain time length after receiving the sterilization signal or the sterilization resuming signal, and then starts sterilization, which can avoid that the user is irradiated by pulse light when the user suddenly opens the refrigerator door, and can also allow the pulse function module to have enough charging time for energy storage, thereby improving the sterilization effect.

[0123] Based on the above embodiment, after the sterilization signal is sent to the pulse function module, the method further comprises:

[0124] Determine that the pulse function module completes sterilization, and reset the standby time length.

[0125] The user triggers a sterilization termination operation, and the standby duration is reset to zero.

[0126] Generally, the refrigerator sterilization can be performed in two ways.

[0127] One is that the user manually starts the sterilization, that is, the user manually triggers the switch key of the pulse function module, or selects the operation of starting the sterilization on the application program of the user terminal, the pulse function module obtains the sterilization signal generated by itself, or obtains the sterilization signal generated by the user terminal in response to the operation of starting the sterilization selected by the user and forwarded by the refrigerator, and emits pulse light based on the sterilization signal to perform sterilization.

[0128] The other is that the refrigerator automatically starts the sterilization, that is, when the standby duration of the pulse function module exceeds the first preset duration, the controller generates and sends a sterilization signal to the pulse function module to trigger the pulse function module to emit pulse light in the refrigerator according to the sterilization mode.

[0129] Specifically, whether the user manually starts the sterilization or the refrigerator automatically starts the sterilization, after the pulse function module completes the sterilization, or before the pulse function module completes the sterilization, but the user closes the ongoing sterilization process of the refrigerator by manually pressing the key or operating the application program, that is, triggers the sterilization termination operation, the controller obtains the sterilization termination signal, resets the standby duration data of the pulse function module to zero, and re-timers the standby duration of the pulse function module, so as to restart the automatic sterilization process when the standby duration of the pulse function module exceeds the first preset duration.

[0130] Optionally, the sterilization termination signal is generated by the pulse function module after completing the sterilization and sent to the controller.

[0131] Optionally, the sterilization termination signal is generated by the controller based on the sterilization required time and the sterilization start time, and the sterilization termination signal is generated by the controller after the sterilization start time elapses for the sterilization required time.

[0132] Optionally, the sterilization termination signal is generated by the pulse function module and sent to the refrigerator when the user triggers the switch key of the pulse function module, that is, triggers the sterilization termination operation. The switch key can be a line control key integrated on the pulse function module, or a virtual key arranged on the control screen of the refrigerator.

[0133] Optionally, the sterilization termination signal is generated by the user terminal and sent to the controller when the user selects the operation of terminating the sterilization on the application program of the user terminal.

[0134] The refrigerator sterilization method provided in the application re-calculates the standby duration of the pulse function module after each sterilization is completed or terminated, and then after each sterilization, even if the user forgets the next sterilization or the user does not start the sterilization function because he or she thinks that manually starting the sterilization is too troublesome, the refrigerator can automatically perform the next sterilization of food, prevent bacteria from growing in the food during refrigeration, and effectively protect the food and the interior of the refrigerator.

[0135] Based on the above embodiment, after the user triggers the sterilization termination operation and resets the standby duration, the method further comprises:

[0136] Determining an irradiation ratio based on the ratio of the irradiation times of the pulse function module emitting pulse light to the preset irradiation times of the sterilization mode.

[0137] Determining a third preset duration based on the product of the first preset duration and the irradiation ratio.

[0138] Updating the first preset duration to the third preset duration.

[0139] Specifically, when the controller determines that the user triggers the sterilization termination operation and the pulse function module terminates emitting pulse light, the controller determines the irradiation times of the pulse function module emitting pulse light according to the sterilization mode based on the sterilization termination signal, obtains the irradiation ratio between the irradiation times and the preset irradiation times of the sterilization mode, and then multiplies the irradiation ratio by the first preset duration to obtain a third preset duration. Then the first preset duration is updated to the calculated third preset duration, the standby duration is reset to zero, and the timing of the standby duration of the pulse function module is re-started. When the standby duration of the pulse function module reaches the third preset duration, the controller generates a new sterilization signal and sends the new sterilization signal to the pulse function module to trigger the pulse function module to emit pulse light in the refrigerator according to the sterilization mode to sterilize the food in the refrigerator.

[0140] Optionally, if the sterilization termination signal is generated by the pulse function module and sent to the controller after the user triggers the switch button of the pulse function module, the sterilization termination signal contains the number of times of pulse light emitted by the pulse function module during the sterilization, and the controller analyzes the number of times from the sterilization termination signal and determines the irradiation ratio based on the ratio between the number of times and the preset irradiation times.

[0141] Optionally, if the sterilization termination signal is generated by the user terminal and sent to the controller after the user selects the operation of terminating sterilization on the application program of the user terminal, the controller forwards the sterilization termination signal to the pulse function module after receiving the sterilization termination signal, controls the pulse function module to stop sterilization and obtains the number of times information fed back by the pulse function module, or the controller receives the sterilization termination signal and forwards it to the pulse function module, controls the pulse function module to stop sterilization, and at the same time, determines the number of times information of the pulse function module emitting pulsed light in this sterilization process through the light signal received by the light sensor, so as to determine the irradiation ratio according to the ratio between the number of times information and the preset irradiation number.

[0142] In an embodiment, the expression of the third preset time length is as follows:

[0143] Wherein, T3 is the third preset time length, T1 is the first preset time length, S1 is the irradiation number of the pulse function module emitting pulsed light according to the sterilization mode, and S is the preset irradiation number of the sterilization mode.

[0144] For example, assuming that the first preset time length T1 is 12h and the preset irradiation number S of the sterilization mode is 180 times. When the pulse function module has performed 72 times of irradiation in the current sterilization process, the user performs the operation of terminating sterilization through the application program of the user terminal, that is, the irradiation number S1 is 72 times, and the third preset time length T3 is calculated to be 4.8h according to 12h*(72÷180). Therefore, after obtaining the sterilization termination signal, if the standby time length of the pulse function module exceeds 4.8h, the controller generates a new sterilization signal and sends it to the pulse function module to trigger the pulse function module to perform a new round of pulsed light emission sterilization according to the preset irradiation number 180 times of the sterilization mode.

[0145] The refrigerator sterilization method provided in the application can shorten the interval time length between the current incomplete sterilization process and the next sterilization, avoid the situation that the current sterilization process is not complete and the user does not actively start sterilization within a certain time length, effectively protect the food and the cleanliness of the refrigerator interior.

[0146] The following provides an embodiment to better illustrate the complete process of the refrigerator sterilization method of the application.

[0147] Fig. 2 is a flowchart of a second embodiment of the sterilization method of the refrigerator according to the present application. As shown in Fig. 2, after the refrigerator is powered on, the standby time of the pulse function module is started. Within the first preset time, the user manually starts the sterilization function through the start button of the pulse function module or the application of the user terminal, and the standby time is restarted. If the standby time of the pulse function module exceeds the first preset time, a sterilization signal is generated.

[0148] Before the controller sends the sterilization signal to the pulse function module, it is further determined whether the refrigerator door is in a closed state. If the refrigerator door is in a closed state, the sterilization signal is sent to the pulse function module to control the pulse function module to emit pulse light according to the sterilization mode. If the refrigerator door is not in a closed state, a light-on signal is generated and sent to the pulse function module to trigger the indicator light connected to the pulse function module to keep on. In this way, the user using the refrigerator is prompted that the sterilization function will be automatically started soon, and the user is required to use the refrigerator as soon as possible and close the refrigerator door. After the door closing signal of the refrigerator door is obtained, the sterilization signal is sent to the pulse function module, and the indicator light is turned off from the on state.

[0149] If the user opens the refrigerator door during the sterilization process of the pulse function module, the controller generates the sterilization signal and the light-on signal and sends them to the pulse function module to control the pulse function module to pause emitting pulse light and keep the indicator light on to remind the user that the refrigerator is being automatically sterilized and the refrigerator door needs to be closed as soon as possible.

[0150] After the user closes the refrigerator door, the controller generates a sterilization resuming signal and sends it to the pulse function module. After receiving the sterilization resuming signal, the pulse function module enters a working preparation state and resumes emitting pulse light in the refrigerator and turns off the indicator light after the working preparation state exceeds a second preset time. After the sterilization is completed, the standby time is reset to zero, and the standby time is restarted to manually sterilize when the user does not start the sterilization function within the first preset time in the next time.

[0151] If the user manually turns off the sterilization function during the sterilization process of the pulse function module, the current sterilization round is not completed but has ended. The controller determines a third preset time as a new first preset time according to the number of irradiation times of the pulse light that has been emitted by the pulse function module during the current sterilization round and the preset irradiation times preset in the sterilization mode, and resets the standby time to zero and restarts the standby time to manually sterilize when the user does not start the sterilization function within the third preset time in the next time.

As shown in Fig. 3, the sterilization method of the refrigerator can be applied to the pulse function module, including but not limited to the following steps 301 and 302.
