[0002] Refrigerators, as refrigeration equipment for food storage and preservation, have become essential household appliances. However, simple low-temperature storage cannot inhibit the activity of all microorganisms, resulting in a limited shelf life. To extend the shelf life of refrigerators, manufacturers often choose to install sterilization devices inside the refrigerator to sterilize the food stored there to inhibit bacterial growth and extend the shelf life of the food. Common sterilization methods include ion sterilization and ultraviolet sterilization. However, both ion sterilization and ultraviolet sterilization can easily cause harm to the human body and have limited effectiveness against bacteria attached to the side walls of storage compartments, shelves, or food packaging.

[0003] To address the significant hazards and poor sterilization effectiveness of traditional sterilization methods, a steam sterilization refrigerator and its control method are disclosed. The steam sterilization refrigerator includes a housing having a refrigeration compartment and a steam generator for supplying steam into the refrigeration compartment. The control method includes: supplying steam to the refrigeration compartment via the steam generator; detecting the temperature within the refrigeration compartment and starting a timer when the temperature reaches a first preset value; controlling the steam generator to stop when the timer reaches the first preset time; and detecting the temperature of the steam generator and controlling the steam generator to stop when the temperature reaches a second preset value. When the temperature of the steam generator reaches 50°C to 80°C, water is supplied to the steam generator at a flow rate of 30 ml / min to 40 ml / min.

[0049] Combine Figures 5 to 7 As shown, an embodiment of the present disclosure provides a refrigerator 6, including a housing 60, a steam generator 70, a water box (not shown in the figure), and a water pump (not shown in the figure). The housing 60 defines a sterilization compartment 610. The steam generator 70 is connected to the sterilization compartment 610 and is used to provide steam to the sterilization compartment 610. The water box is connected to the steam generator 70 and is used to store water. The water pump is arranged between the water box and the steam generator 70 and is used to control the flow of water entering the steam generator 70. The refrigerator 6 also includes a processor 510 and a memory 520. The memory 520 is used to store program instructions. The processor 510 can call the program instructions stored in the memory 520.

[0050] The embodiment of the present disclosure provides a sterilization control method for a refrigerator, which can be run on a refrigerator 6. Figure 1 As shown, the sterilization control method includes:

[0051] S101: The processor obtains the water temperature of the water box.

[0052] S102, the processor adjusts the water pump opening according to the water temperature of the water box to adjust the steam temperature in the sterilization room.

[0053] The sterilization control method for a refrigerator provided by the disclosed embodiments can adjust the opening of the water pump by adjusting the water temperature in the water box, thereby regulating the steam temperature in the sterilization room and achieving steam temperature control in the sterilization room. By controlling the steam temperature in the sterilization room, the stability of the steam temperature in the sterilization room is improved, so that the steam temperature in the sterilization room meets the sterilization needs of the user, thereby improving the sterilization effect of the refrigerator. At the same time, the opening of the water pump is adjusted by adjusting the water temperature in the water box to adjust the steam temperature in the sterilization room. The water temperature state in the water box is utilized to control the opening of the water pump and thus the water flow rate of the water pump, thereby avoiding excessive energy waste and improving the energy utilization rate of the refrigerator.

[0054] Combine Figure 2 As shown, the embodiment of the present disclosure provides another sterilization control method for a refrigerator, comprising:

[0055] S201: The processor obtains the water temperature of the water box.

[0056] S202: The processor determines the maximum water pump flow rate according to the water temperature of the water box.

[0057] S203: The processor determines the water pump flow rate according to the maximum water pump flow rate.

[0058] S204: The processor adjusts the water pump opening according to the water pump flow rate to adjust the steam temperature in the sterilization room.

[0059] In this embodiment, the maximum water pump flow rate corresponding to the current water box temperature can be determined based on the water box temperature. Based on the maximum water pump flow rate, the water pump flow rate that meets user needs is then determined. The water pump opening is determined based on the water pump flow rate. Different water box water temperatures correspond to different maximum water pump flows, and thus different water pump flows and pump openings, thus enabling control of the water pump opening based on the water box temperature. Related art proposes supplying water to the steam generator at a flow rate of 30 ml / min to 40 ml / min when the steam generator temperature reaches a temperature threshold to prevent hot water from splashing out of the steam generator. Compared to related art, the water pump opening adjustment method provided in this embodiment eliminates the step of comparing the steam generator temperature with the temperature threshold. Instead, the water pump opening is determined based on the maximum water pump flow rate, which is determined by the water box temperature. By limiting the maximum water pump flow rate, hot water splashing out of the steam generator is prevented. Furthermore, by determining the water pump opening based on the maximum water pump flow rate, the steam generator water supply becomes more flexible, thereby enhancing the flexibility of this method.

[0060] Optionally, the step of determining the maximum water pump flow rate according to the water temperature of the water box includes: calculating Get the maximum pump flow q max Where P represents the heating power of the steam generator and T represents the water temperature of the water box.

[0061] In this embodiment, P represents the heating power of the steam generator, T represents the water temperature of the water box, and q max Indicates the maximum water pump flow rate. Since the specific heat capacity of water is 4.2kJ / (kg·℃), and the latent heat of vaporization of water is 2257.2kJ / kg at standard atmospheric pressure, the steam generator can pump The water is converted into water vapor. Therefore, the maximum water pump flow is defined as The unit is kg / min. The maximum flow rate of the water pump is defined by the water temperature in the water box and the heating power of the steam generator. Setting the maximum flow rate limit ensures that all water entering the steam generator through the water pump is converted into steam. This avoids excessive water flow from the water pump, which causes excessive water to enter the steam generator, resulting in some water not being converted into steam and remaining in the steam generator, leading to energy waste.

[0062] For example, when the water temperature of the water box is 30°C and the heating power of the steam generator is 1000W, the maximum water pump flow rate is When the water temperature of the water box is 50℃ and the heating power of the steam generator is 1000W, the maximum water pump flow rate is

[0063] It should be noted that the heating power of the steam generator needs to be specifically set or selected by researchers based on the actual specifications and dimensions of the refrigerator. This solution only provides some embodiments, and the specific value of the steam generator heating power is not specified here.

[0064] Optionally, the step of determining the water pump flow rate according to the maximum water pump flow rate includes: calculating q = q max ×[1-(n-1)k], the water pump flow rate q is obtained. Where n represents the sterilization gear of the refrigerator, and k represents the flow gradient coefficient of the water pump.

[0065] In this embodiment, n represents the sterilization gear of the refrigerator, k represents the flow gradient coefficient of the water pump, and q represents the water pump flow rate. The sterilization gear n of the refrigerator is set by the user according to the needs, and the flow gradient coefficient k of the water pump is a constant, so the water pump flow rate q is defined as q = q max ×[1-(n-1)k], so that the water pump flow rate q depends on the sterilization gear n set by the user and the maximum water pump flow rate q max . Maximum pump flow q max It refers to the amount of water that is completely converted into water vapor per minute when the water enters the steam generator through the water pump under the current water box temperature. This amount of water flows through all the paths in the steam generator and is completely converted into water vapor. The water pump flow rate q = q max ×[1-(n-1)k] and the water pump flow gradient coefficient k, where n refers to the sterilization level set by the user. The water pump flow rate q is determined based on the sterilization level n and the water pump flow gradient coefficient k. Based on the water pump flow rate q, the pump opening is controlled to regulate the amount of water entering the steam generator through the water pump. This advances the point at which the water is completely converted into water vapor after passing through the steam generator. The converted water vapor continues to absorb heat along the remaining path, raising its temperature, thereby increasing the steam temperature in the sterilization room and enabling regulation of the steam temperature within the sterilization room.

[0066] For example, the flow gradient coefficient k of the water pump is 0.1, and the maximum water pump flow q at this time is maxWhen it is 0.0235 kg / min and the sterilization gear position n of the refrigerator set by the user is 5, the water pump flow rate q at this time is q = 0.0235 kg / min × [1 - (5 - 1) × 0.1] = 0.0141 kg / min. When the sterilization gear position n of the refrigerator set by the user is 6, the water pump flow rate q at this time is q = 0.0235 kg / min × [1 - (6 - 1) × 0.1] = 0.0118 kg / min. As the sterilization gear position n of the refrigerator set by the user increases, the water pump flow rate q decreases, the amount of water entering the steam generator through the water pump decreases, the position where all the water is converted into water vapor in the steam generator is advanced, the remaining path that the converted water vapor passes through in the steam generator increases, the temperature of the water vapor rises, and the steam temperature in the sterilization chamber rises.

[0067] Optionally, the value range of k is: where N represents the number of sterilization gear positions of the refrigerator.

[0068] In this embodiment, N represents the number of sterilization gear positions of the refrigerator, and the value range of k is Exemplarily, when N takes the value of 9, the value range of k is 0 < k ≤ 0.125. More specifically, the value of k can be 0.025, 0.05, 0.075, 0.1 or 0.125. <U+

[0069] It should be noted that the number of sterilization gear positions N of the refrigerator and the flow gradient coefficient k of the water pump need to be specifically set by researchers according to the actual specifications of the refrigerator or the steam generator. Only some embodiments are given in this solution, and only the value of k needs to meet the conditions. The specific values of the number of sterilization gear positions N of the refrigerator and the flow gradient coefficient k of the water pump are not specified here.

[0070] Optionally, the steps of adjusting the water pump opening according to the water pump flow rate include: reducing the water pump opening when the water pump flow rate decreases; or increasing the water pump opening when the water pump flow rate increases; where the smaller the opening of the water pump, the higher the steam temperature in the sterilization chamber.

[0071] In this embodiment, the higher the sterilization gear position n of the refrigerator set by the user, the smaller the water pump flow rate, the smaller the opening of the water pump, the more heat the water vapor absorbs, and the higher the steam temperature in the sterilization chamber. It enables the user to adjust the water pump opening by adjusting the sterilization gear position of the refrigerator, and further adjust the steam temperature in the sterilization chamber. It enables the user to select the sterilization gear position according to their own needs and realize the selection of the sterilization steam temperature.

[0072] Combined with Figure 3 As shown, another sterilization control method for a refrigerator provided by an embodiment of the present disclosure includes:

[0073] S301: The processor obtains the water temperature of the water box.

[0074] S302: The processor determines the maximum water pump flow rate according to the water temperature of the water box.

[0075] S303: The processor determines the water pump flow rate according to the maximum water pump flow rate.

[0076] S304: The processor adjusts the water pump opening according to the water pump flow rate to adjust the steam temperature in the sterilization room.

[0077] S305: The processor obtains the steam temperature in the sterilization room.

[0078] S306: When the steam temperature is greater than the temperature threshold, the processor starts calculating the running time.

[0079] S307: The processor controls the steam generator to be turned on or off according to the operating time.

[0080] In this embodiment, the sterilization mode of the refrigerator can be turned on or off by measuring the steam temperature in the sterilization room and starting to calculate the operating time when the steam temperature exceeds a temperature threshold. By restarting the sterilization mode operating time when the steam temperature exceeds the temperature threshold, items can be fully sterilized while meeting the user's sterilization temperature requirements, further improving the refrigerator's sterilization effectiveness.

[0081] Optionally, there is a mapping relationship between the temperature threshold and the sterilization level of the refrigerator, and the higher the sterilization level of the refrigerator, the higher the temperature threshold.

[0082] In this embodiment, a preset mapping relationship exists between the temperature threshold and the sterilization level of the refrigerator. The higher the sterilization level, the higher the temperature threshold. This pre-set mapping relationship allows different sterilization levels of the refrigerator to correspond to different temperature thresholds, allowing the user to select the sterilization steam temperature by simply setting the sterilization level. During the sterilization process, different foods or items have different heat tolerances. By enabling users to select the sterilization steam temperature by setting the sterilization level, the refrigerator's universal applicability is enhanced, improving the user experience.

[0083] For example, when the sterilization level n of the refrigerator is 1, the corresponding temperature threshold is 100° C. When the sterilization level n of the refrigerator is 2, the corresponding temperature threshold is 110° C.

[0084] It should be noted that the mapping relationship between the temperature threshold and the sterilization level of the refrigerator needs to be specifically set by researchers based on the actual specifications and dimensions of the refrigerator or steam generator. This solution only provides some implementation examples, and the specific mapping relationship between the temperature threshold and the sterilization level of the refrigerator is not specified here.

[0085] Optionally, the step of controlling the steam generator to turn on or off according to the operating time includes: controlling the steam generator to turn on when t≤t0; or controlling the steam generator to turn off when t≥t0; wherein t represents the operating time, and t0 represents the sterilization time of the refrigerator.

[0086] In this embodiment, t represents the runtime, which begins when the steam temperature exceeds a threshold. t0 represents the sterilization duration of the refrigerator, which is user-configurable. By controlling the steam generator to remain on when t ≤ t0, or to shut it off when t ≥ t0, the steam generator is turned on or off, thereby controlling the sterilization mode of the refrigerator.

[0087] Furthermore, in related art, by monitoring the temperature inside the refrigeration compartment and the temperature of the steam generator, the steam generator is controlled to start and stop, causing the steam generator to operate intermittently, resulting in unstable steam temperature in the refrigeration compartment. Compared with related art, by controlling the steam generator to continuously operate when t≤t0, the steam generator is controlled to continuously supply steam to the sterilization compartment, thereby improving the stability of the steam temperature in the sterilization compartment and enhancing the sterilization effect of the refrigerator.

[0088] For example, if the user sets the refrigerator's sterilization level to 1 and the sterilization duration to 20 minutes, the corresponding temperature threshold is 100°C. When the steam temperature in the sterilization room exceeds 100°C, the run time t begins to be calculated. If t ≤ 20 minutes, the steam generator is controlled to remain on until t ≥ 20 minutes, at which point it is controlled to shut off, exiting sterilization mode.

[0089] Combine Figure 4 As shown, an embodiment of the present disclosure provides a sterilization control device 40 for a refrigerator, comprising an acquisition module 410 and a control module 420. The acquisition module 410 is configured to acquire the water temperature of the water box; the control module 420 is configured to adjust the water pump opening according to the water temperature of the water box to regulate the steam temperature in the sterilization room.

[0090] The sterilization control device 40 for a refrigerator provided in the disclosed embodiments can adjust the water pump opening by adjusting the water temperature in the water box. Adjusting the water pump opening adjusts the steam temperature in the sterilization chamber, thereby achieving steam temperature control within the sterilization chamber. By controlling the steam temperature within the sterilization chamber, the stability of the steam temperature within the sterilization chamber is improved, ensuring that the steam temperature within the sterilization chamber meets the user's sterilization requirements, thereby improving the sterilization effectiveness of the refrigerator.

[0091] Combine Figure 5 As shown, an embodiment of the present disclosure provides a sterilization control device 50 for a refrigerator, comprising a processor 510 and a memory 520. Optionally, the device 50 may further comprise a communication interface 530 and a bus 540. The processor 510, the communication interface 530, and the memory 520 may communicate with each other via the bus 540. The communication interface 530 may be used for information transmission. The processor 510 may call the logic instructions in the memory 520 to execute the sterilization control method for the refrigerator of the above embodiment.

[0092] In addition, the logic instructions in the memory 520 can be implemented in the form of software functional units and can be stored in a computer-readable storage medium when sold or used as an independent product.

[0093] Memory 520, as a computer-readable storage medium, can be used to store software programs and computer-executable programs, such as the program instructions / modules corresponding to the methods in the embodiments of the present disclosure. Processor 510 executes the program instructions / modules stored in memory 520 to perform functional applications and data processing, thereby implementing the sterilization control method for refrigerators in the above-mentioned embodiments.

[0094] The memory 520 may include a program storage area and a data storage area. The program storage area may store an operating system and application programs required for at least one function; the data storage area may store data generated based on the use of the terminal device. Furthermore, the memory 520 may include high-speed random access memory and non-volatile memory.

The water box is connected to the steam generator 70 and is located below the heat dissipation coil. The heat dissipation coil is used to preheat the water in the water box. The water pump is arranged between the water box and the steam generator 70. The opening of the water pump is used to control the steam temperature in the sterilization chamber 610. The opening of the water pump is determined according to the water temperature of the water box.

[0096] In this embodiment, the housing 60 defines a sterilization compartment 610. In the related art, the refrigeration compartment and the sterilization compartment are the same compartment. During the sterilization mode, food or items that do not require sterilization need to be removed. Compared with the related art, by separately defining the sterilization compartment 610, the user does not need to remove food or items that do not require sterilization during the sterilization process, thereby improving the convenience of use of the refrigerator 6. The water box is located below the heat dissipation coil. By utilizing the waste heat generated by the heat dissipation coil connected to the compressor and condenser, the heat dissipation coil preheats the water in the water box, and the water in the water box pre-cools the refrigerant flowing through the heat dissipation coil, thereby improving the steam conversion efficiency and cooling efficiency of the refrigerator 6 and improving the energy utilization efficiency of the refrigerator 6.

[0097] In addition, the water pump opening can control the steam temperature in the sterilization chamber 610. The water pump opening is determined by the water temperature in the water box. The water temperature in the water box can be used to adjust the water pump opening, thereby regulating the steam temperature in the sterilization chamber 610. This achieves steam temperature control in the sterilization chamber 610, improves the stability of the steam temperature in the sterilization chamber 610, and enhances the sterilization effect of the refrigerator 6.

[0098] Optionally, combined Figure 6 As shown, the box body 60 further defines a refrigeration compartment 620 and / or a freezer compartment 630 , wherein a heat-insulating material 640 is provided between the sterilization compartment 610 and the refrigeration compartment 620 and / or the freezer compartment 630 .

[0099] In this embodiment, the sterilization compartment 610 is independently configured from the refrigeration compartment 620 and / or the freezer compartment 630. In the related art, the refrigeration compartment and the sterilization compartment are the same compartment, and refrigeration needs to be stopped during the sterilization mode. Compared to the related art, by separately defining the sterilization compartment 610 and the refrigeration compartment 620 and / or the freezer compartment 630, the refrigerator 6 does not need to stop refrigeration during the sterilization process, thereby improving the convenience of use of the refrigerator 6. In addition, if the refrigeration compartment and the sterilization compartment are the same compartment, when refrigeration is resumed after sterilization, the refrigerator refrigeration compartment starts at a higher temperature, consuming more refrigerator energy to bring the refrigeration compartment to the refrigeration or freezing temperature. By independently providing the sterilization compartment 610 and the refrigeration compartment 620 and / or the freezer compartment 630, and providing an insulation material 640 between the sterilization compartment 610 and the refrigeration compartment 620 and / or the freezer compartment 630, the sterilization mode and the refrigeration mode of the refrigerator 6 can be performed simultaneously, and the high-temperature steam generated during the sterilization process of the refrigerator will not affect the refrigeration of the refrigerator. Compared with the related art, the energy consumption of the refrigerator is reduced.

[0100] Optionally, combined Figure 7 and Figure 8 As shown, the steam generator 70 includes a housing 710, a heating element 720, and a plurality of shelves 730. The housing 710 defines a heating chamber 712 and a mounting chamber (not shown). The heating chamber 712 is connected to the sterilization chamber 610 and the water box. The heating element 720 is disposed in the mounting chamber. The plurality of shelves 730 are arranged in a predetermined pattern within the heating chamber 712 to form a flow path within the heating chamber 712.

[0101] In this embodiment, a heating element 720 is disposed within the mounting cavity and is used to heat water flowing through the heating cavity 712, converting the water within the heating cavity 712 into steam, thereby providing steam for the sterilization heating chamber. A plurality of shelves 730 are provided within the heating cavity 712. The shelves 730 are arranged in a predetermined pattern to form flow channels within the heating cavity 712 for water to circulate. Forming flow channels within the heating cavity 712 increases the path through which water circulates within the steam generator 70, allowing the water to absorb sufficient heat within the steam generator 70 for conversion to steam, thereby improving the steam conversion efficiency of the steam generator 70.

[0102] It should be noted that the number and arrangement of the shelves 730 need to be specifically set by researchers based on the actual specifications and dimensions of the refrigerator 6 or steam generator 70, and are not specified here.

[0103] Optionally, the refrigerator 6 further includes an evaporator (not shown), a water receiving tank (not shown), and a first drain pipe (not shown). The water receiving tank is located below the evaporator and is used to collect condensed water generated by the evaporator. The water inlet of the first drain pipe is connected to the water receiving tank, and the water outlet of the first drain pipe is connected to the water box.

[0104] In this embodiment, a water collection tank is provided below the evaporator to collect condensed water generated by the evaporator. The water collection tank is connected to the water box via a first drain pipe, which directs water from the water collection tank to the water box, where it is used as a water source for steam generator 70 to generate steam. By collecting condensed water from the evaporator and using it as a water source for steam generator 70 to generate steam, wastewater is reused, improving the energy efficiency of refrigerator 6.

[0105] Optionally, combined Figure 6 and Figure 7 As shown, the refrigerator 6 further includes a second drain pipe 80. The water inlet of the second drain pipe 80 is connected to the sterilization chamber 610 for draining the water in the sterilization chamber 610.

[0106] In this embodiment, a second drain pipe 80 is provided to drain the water generated in the sterilization chamber 610 to prevent the water formed by condensation of water vapor in the sterilization chamber 610 from being retained in the sterilization chamber 610 and affecting the user's refrigerator experience.

[0107] Optionally, combined Figure 6 As shown, the refrigerator 6 also includes a sterilization control device 40 (50) for the refrigerator 6 as described in any of the above embodiments.
