[0045] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0046] In the description of the present application, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0047] In the description of this application, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0048] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0049] In some cases, the storage drawers of existing refrigerators accurately match the air volume through stratified air supply, and the bottom sensor is linked to the top sensor to monitor the meat temperature changes in real time to adjust the space temperature, so that the meat temperature is accurately controlled at the freezing point. This technology is currently used in single-system refrigerators, where the refrigeration humidity is relatively low (30% to 50%), and the risk of condensation and icing is small. When used in dual-system refrigerators, such as Figure 4 A dual-system refrigerator is provided with a freezing evaporator 204 and a refrigerating evaporator 203. The refrigerating capacity of the refrigerating evaporator 203 is driven by a refrigerating fan 201 to cool the refrigerating chamber and the storage drawer 207. When the temperature of the refrigerating chamber is lower than the set temperature, the refrigerating air door 202 is opened, and the refrigerating air duct 206 is connected to the refrigerating chamber. When the temperature of the storage drawer 207 is lower than the set temperature, the drawer air door 208 is opened, and the refrigerating air duct 206 is connected to the storage drawer 207, thereby cooling the storage drawer 207.

[0050] When the refrigerated evaporator 203 is used to supply air to the storage drawer 207, due to the high refrigerated humidity (60% to 80%) and the low temperature of the storage drawer (-2°C to 3°C), the temperature at the bottom of the storage drawer 207 is likely to be lower than the dew point temperature, resulting in condensation or even ice on the box and the side walls of the storage drawer 207. If condensation and ice form on the guide rail of the storage drawer 207, there is a risk of corrosion or jamming of the guide rail, thereby affecting the user experience. In this regard, the current solution is to add an integrated barrel to seal and insulate against water vapor, but the overall cost of this structure is high and the structural design is relatively complex.

[0051] Based on the above situation, the embodiment of the present application proposes a dehumidification and anti-condensation control method, controller, refrigerator and storage medium for a refrigerator, aiming to achieve a low-cost solution to the condensation and icing problem caused by high refrigeration humidity in a dual-system refrigerator.

[0052] The following is a further description of various embodiments of the refrigerator of the present application in conjunction with the accompanying drawings.

[0053] like Figures 1 to 4 As shown, Figure 1 is an exploded schematic diagram of a storage drawer of a dual-system refrigerator provided by an embodiment of the present application; Figure 2 is a cross-sectional schematic diagram of a storage drawer of a dual-system refrigerator provided by an embodiment of the present application; Figure 3 This application Figure 2 A magnified view of part A; Figure 4 It is a schematic diagram of the structure of a dual-system refrigerator provided by an embodiment of the present application.

[0054] In one embodiment, the refrigerator includes but is not limited to a refrigerating chamber and a humidity sensor 101 , wherein the humidity sensor 101 is used to detect the humidity of the surrounding air of the storage drawer 207 .

[0055] In one embodiment, the refrigerator is further provided with a refrigerating fan 201 , a refrigerating damper 202 , a refrigerating evaporator 203 , a freezing evaporator 204 , a freezing air duct 205 , a refrigerating air duct 206 , a storage drawer 207 , and a drawer damper 208 .

[0056] In one embodiment, the refrigeration fan 201 can be set at the back of the cold storage room and installed inside the back plate of the refrigeration air duct 206, wherein the air blown out by the refrigeration fan 201 will enter the cold storage room. Specifically, the refrigeration fan 201 circulates the wind in the entire cold storage room, and can bring the cold energy of the evaporator to the outside of the back plate through the fan, thereby playing a role in cooling the cold storage room. When defrosting, the refrigeration fan 201 brings the hot air outside the back plate to the evaporator, and uses the external hot air to make the frost on the evaporator absorb heat and melt, thereby achieving the defrosting effect.

[0057] In one embodiment, the refrigerator is further provided with a drawer fan 102, which is installed on the outside of the storage drawer 207, wherein the air blown out by the drawer fan 102 will not enter the storage drawer 207, but flows around the storage drawer 207. Specifically, the main function of the drawer fan 102 is to strengthen the air disturbance around the storage drawer 207 under high humidity conditions, so as to prevent the surrounding high humidity air from condensing into droplets on the wall of the storage drawer 207.

[0058] In one embodiment, the humidity sensor 101 is provided with a probe 116 for detecting the humidity value of the surrounding air of the storage drawer 207 of the refrigerator.

[0059] In one embodiment, the storage drawer 207 of the refrigerator further includes a first drawer 112, a first drawer air supply duct 106, a fan fixing cover 110, a drawer fan air outlet 113, and a drawer layer plate 114. The drawer fan 102 is arranged above the fan fixing cover 110, the first drawer 112 is arranged below the fan fixing cover 110, the first drawer air supply duct 106 is arranged at one end of the fan fixing cover 110, the drawer fan 102 is provided with a drawer fan air outlet 113, and the drawer layer plate 114 is arranged at the top of the drawer fan 102.

[0060] In one embodiment, the storage drawer 207 of the refrigerator further includes an air duct cover plate 103, an air duct foam 104, a freezing return air duct 105, and a drawer air duct air inlet 115. The air duct cover plate 103 is arranged around the air duct foam 104, the freezing return air duct 105 is arranged below the first drawer 112, and the drawer air duct air inlet 115 is arranged above the fan fixing cover 110 and connected to the drawer layer plate 114.

[0061] In one embodiment, the storage drawer 207 of the refrigerator further includes a second drawer 107, a second drawer return air port 108, an air outlet 109 of the air supply duct inside the second drawer, and an air inlet 111 of the air supply duct inside the second drawer. The second drawer return air port 108 is installed on a first side of the second drawer 107, the air outlet 109 of the air supply duct inside the second drawer is installed on a second side of the second drawer 107, and the air inlet 111 of the air supply duct inside the second drawer is installed at the top position of the second drawer 107.

[0062] Based on the hardware structure of the refrigerator in each of the above-mentioned embodiments, various embodiments of the dehumidification and anti-condensation control method for the refrigerator of the present application are respectively proposed below.

[0063] like Figure 5 As shown, Figure 5 It is a flow chart of a dehumidification and anti-condensation control method for a refrigerator provided by an embodiment of the present application; the dehumidification and anti-condensation control method for a refrigerator may include but is not limited to step S510 and step S520.

[0064] Step S510, collecting the humidity value of the air around the storage drawer through the humidity sensor;

[0065] Step S520: When the humidity value is greater than or equal to the first preset value, increase the temperature of the storage drawer.

[0066] In one embodiment, first, when it is determined that the humidity sensor is working, the embodiment of the present application will collect the humidity value of the surrounding air of the storage drawer; then, if the humidity value is greater than or equal to the first preset value, it indicates that condensation and icing are likely to occur at this time. In this regard, the embodiment of the present application can reduce condensation and frost caused by the drawer temperature being lower than the dew point temperature by increasing the temperature of the storage drawer. Therefore, the embodiment of the present application does not need to add an integrated barrel sealing and heat preservation structure, so that the condensation or icing problem caused by high refrigeration humidity can be solved at a low cost.

[0067] It should be noted that, regarding the method of obtaining the humidity value, the embodiment of the present application can add a humidity sensor at a peripheral position on the outer side of the storage drawer, and collect the humidity value through the humidity sensor.

[0068] In addition, it can be understood that the type of humidity sensor may be a capacitive humidity sensor, a resistive humidity sensor, a semiconductor humidity sensor, an ultrasonic humidity sensor, or other types of humidity sensors. The embodiments of the present application do not limit the specific type of the humidity sensor.

[0069] It is understandable that the first preset value mentioned above may be preset by a user or a system. The user or the system can set the specific value of the first preset value, and the embodiment of the present application does not specifically limit the value of the first preset value.

[0070] In addition, if Figure 6 As shown, Figure 6 This application Figure 5 A sub-flowchart of step S510; regarding the above step S510 in which the humidity value of the surrounding air of the storage drawer is collected by the humidity sensor, it may include but is not limited to step S610 and step S620.

[0071] Step S610, receiving a refrigerator door closing instruction;

[0072] Step S620: activating the humidity sensor to collect the humidity value of the air around the storage drawer according to the refrigerator door closing instruction.

[0073] In one embodiment, a door opening / closing sensor on the refrigerator door receives a signal indicating that the refrigerator door is closed, and then the control system responds to the signal indicating that the refrigerator door is closed. Upon receiving the refrigerator door closing instruction, the humidity sensor is activated to collect the humidity value of the surrounding air of the storage drawer, and then the humidity value is compared with a first preset value to determine whether the storage drawer control temperature needs to be increased.

[0074] It should be noted that regarding the method of receiving the refrigerator door closing instruction, the embodiment of the present application can add a refrigerator door switch sensor at the position of the refrigerator door, and receive the refrigerator door closing instruction through the door switch sensor.

[0075] In addition, it can be understood that the type of the refrigerator door switch sensor can be a mechanical switch, a reed switch, a capacitive sensor, an inductive sensor, an ultrasonic sensor, or other types of refrigerator door switch sensors. The embodiments of the present application do not limit the specific type of the refrigerator door switch sensor.

[0076] like Figure 7 As shown, Figure 7 This application Figure 5 Another sub-flow chart of step S510; regarding the humidity value of the surrounding air of the storage drawer collected by the humidity sensor in the above step S510, it may include but is not limited to step S710 and step S720.

[0077] Step S710, collecting sampled humidity values ​​at multiple times within a preset time period through a humidity sensor;

[0078] Step S720: determine a humidity value according to a plurality of sampled humidity values, wherein the humidity value is one of the following: an average humidity value, a median humidity value, and a mode humidity value.

[0079] It should be noted that the above-mentioned preset duration can be preset by the user or the system. The user or the system can set the specific value of the preset duration according to their own needs, and the embodiment of the present application does not specifically limit the value of the preset duration. Thereby, the preset duration can be made more reasonable, which not only better guarantees the normal operation of the system, but also makes the sampled humidity value more accurate.

[0080] It can be understood that the average humidity value is the value obtained by adding the sum of the sampled humidity values ​​collected at multiple moments within multiple preset time periods and dividing it by the number of multiple moments; the median humidity value is the value obtained by sorting the sampled humidity values ​​collected at multiple moments within multiple preset time periods in sequence. When the number of sampled humidity values ​​is n and n is an odd number, the median is the (n+1) / 2th number; when the number of sampled humidity values ​​is n and n is an even number, the median is the average of the n / 2th number and the n / 2+1th number; the mode humidity value is the sampled humidity value that appears most frequently among the sampled humidity values ​​collected at multiple moments within the preset time period.

[0081] like Figure 8 As shown, Figure 8 This application Figure 5A sub-flow chart of step S520 in the figure; regarding the above step S520, the temperature of the storage drawer is increased by the following steps, which may include but are not limited to step S810 and step S820.

[0082] Step S810, determining the target upward adjustment range according to the humidity value;

[0083] Step S820: Increase the temperature of the storage drawer based on the target increase amplitude.

[0084] In one embodiment, there is a positive correlation between the target upward adjustment amplitude and the humidity value, that is, the larger the humidity value, the larger the target upward adjustment amplitude, that is, each humidity value has a corresponding target upward adjustment amplitude.

[0085] In one embodiment, all humidity values ​​are set to multiple humidity intervals, each humidity interval corresponds to a target increase range, and the target increase range corresponding to a higher humidity interval is greater than the target increase range corresponding to a lower humidity interval.

[0086] It is understandable that increasing the temperature of the storage drawer after determining the increase range is helpful to improve the accuracy of increasing the temperature of the storage drawer.

[0087] In addition, if Fig. 9 As shown, Fig. 9 This application Figure 8 A sub-flowchart of step S810 in FIG. 8 ; regarding the above step S810, it may include but is not limited to step S910 and step S920.

[0088] Step S910: when the humidity value is greater than or equal to a first preset value and less than or equal to a second preset value, taking a first upward adjustment range as a target upward adjustment range, wherein the first preset value is less than the second preset value;

[0089] Step S920: When the humidity value is greater than the second preset value, the second increase range is used as the target increase range, wherein the second increase range is greater than the first increase range.

[0090] It is understandable that the second preset value mentioned above may be preset by a user or a system. The user or the system can set the specific value of the second preset value, and the embodiment of the present application does not specifically limit the value of the second preset value.

[0091] Specifically, for a refrigerator equipped with a humidity sensor, the embodiment of the present application can determine the target upward adjustment amplitude based on the current humidity value. If the humidity value is less than a first preset value, the target upward adjustment amplitude will not be adjusted; if the humidity value is greater than or equal to the first preset value and less than or equal to the second preset value, the first upward adjustment amplitude will be used as the target upward adjustment amplitude, wherein the first preset value is less than the second preset value; if the humidity value is greater than the second preset value, the second upward adjustment amplitude will be used as the target upward adjustment amplitude, wherein the second upward adjustment amplitude is greater than the first upward adjustment amplitude.

[0092] In addition, if Fig.10 As shown, Fig.10 It is a subsequent flow chart after increasing the temperature of the storage drawer provided by an embodiment of the present application; after increasing the temperature of the storage drawer, the method may also include but is not limited to step S1010, step S1020 and step S1030.

[0093] Step S1010, start timing;

[0094] Step S1020: When the timing time is greater than or equal to the preset time, a reminder message is pushed to the user to remind the user to check the closing status of the refrigerator door and / or storage drawer;

[0095] Step S1030: When the timing time is less than the preset time, the humidity value of the air surrounding the storage drawer continues to be collected through the humidity sensor.

[0096] In addition, it is worth noting that the timing start time refers to the time when the temperature of the storage drawer is increased, so as to calculate the time when the temperature of the storage drawer is increased.

[0097] In one embodiment, after the temperature of the storage drawer is increased, the timer starts timing, and when the temperature of the storage drawer is restored, the timer stops timing and the accumulated time of the timer is reset to zero, and when the temperature of the storage drawer is increased again, the timer starts timing again.

[0098] Specifically, the embodiment of the present application can compare the increased temperature of the storage drawer and the preset time. After the temperature of the storage drawer is increased, the timing time is greater than or equal to the preset time and the humidity has not been significantly reduced, which indicates that the dehumidification effect has been low, indicating that the refrigerator door may not be closed tightly. The refrigerator will then push a reminder message to the user to remind the user to check the closing status of the refrigerator door and / or the storage drawer; after the temperature of the storage drawer is increased, the humidity has decreased during the period when the timing time is less than the preset time. In this regard, the embodiment of the present application will continue to collect the humidity value of the surrounding air of the storage drawer through the humidity sensor.

[0099] In one embodiment, the reminder information can be pushed to the user through a display panel or a buzzer to remind the user to check the closing status of the door and / or storage drawer of the refrigerator. If the full water reminder information is pushed to the user through the display panel, the display panel can design a user interface for the reminder information, and the user interface includes but is not limited to the text, icon or animation of the reminder information. Then determine the display mode of the reminder information, and the display mode includes but is not limited to full screen display, pop-up window or status bar notification. If the reminder information is pushed to the user through a buzzer, the buzzer can set the reminder duration, number of reminders, reminder interval duration and the volume of the buzzer sound during the reminder.

[0100] In one embodiment, when the humidity value is greater than or equal to a first preset value, the refrigeration level of the refrigeration chamber is increased, wherein the refrigeration level includes at least one of the following: refrigeration time and refrigeration frequency.

[0101] In one embodiment, the refrigeration level of the refrigeration chamber is increased by extending the refrigeration time and increasing the refrigeration frequency. Extending the refrigeration time and increasing the refrigeration frequency is equivalent to extending the dehumidification time and enhancing the dehumidification capacity, thereby achieving the effect of reducing condensation and icing.

[0102] It should be noted that the above-mentioned cooling time can be preset by the user or the system. The user or the system can set the specific value of the cooling time according to their own needs, and the embodiment of the present application does not specifically limit the value of the cooling time.

[0103] It should be noted that the above-mentioned refrigeration frequency can be preset by the user. The user can set the specific value of the refrigeration frequency according to his own needs, and the embodiment of the present application does not specifically limit the value of the refrigeration frequency.

[0104] It is understandable that the refrigeration level of the refrigerating chamber can be increased by extending the refrigeration time alone, by increasing the refrigeration frequency alone, or by extending the refrigeration time and increasing the refrigeration frequency at the same time, and the dehumidification time can be extended and the dehumidification capacity can be enhanced by extending the refrigeration time and / or increasing the refrigeration frequency.

[0105] In one embodiment, after collecting the humidity value of the surrounding air of the storage drawer by the humidity sensor, the method further includes:

[0106] When the humidity value is less than the first preset value, the refrigeration gear of the refrigeration chamber is restored to the original setting gear, and the control temperature of the storage drawer is restored to the original setting temperature.

[0107] It is understandable that the above-mentioned set temperature may be preset by a user or a system. The user or the system may set a specific value of the set temperature, and the embodiment of the present application does not specifically limit the value of the set temperature.

[0108] In one embodiment, when the humidity value is greater than or equal to the first preset value, the embodiment of the present application can first increase the refrigeration level of the refrigeration chamber, and then determine whether to increase the temperature of the storage drawer. For example, if the humidity value of the surrounding air of the storage drawer is less than the first preset value after the preset time after the refrigeration level of the refrigeration chamber is increased, then there is no need to increase the temperature of the storage drawer. By setting it in this way, the preservation effect of the food in the storage drawer can be guaranteed first, thereby retaining the nutritional value and taste experience of the food.

[0109] The storage drawer of the embodiment of the present application can keep meat and seafood ingredients fresh for many days under refrigerated conditions without freezing, thereby retaining the nutritional value and taste experience of the ingredients. A metal tray is designed at the bottom of the storage drawer, which can accurately monitor and transmit the temperature changes of the ingredients, achieving a micro-crystallized but not frozen state.
