[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] The following further describes various embodiments of the refrigerator of the present application in conjunction with the accompanying drawings.

[0055] 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 in one embodiment of the present application.

[0056] 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 .

[0057] 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 .

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] Based on the hardware structure of the dual-system refrigerator in each of the above-mentioned embodiments, various embodiments of the dehumidification and anti-condensation control method of the refrigerator of the present application are respectively proposed below.

[0065] 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.

[0066] Step S510: collecting the humidity value of the air around the storage drawer through a humidity sensor;

[0067] Step S520: When the humidity value is greater than or equal to the first preset value, the drawer fan is controlled to start working.

[0068] In one embodiment, first, when it is determined that the humidity sensor is in operation, the embodiment of the present application will collect the humidity value of the air surrounding the storage drawer; then, if the humidity value is greater than or equal to the first preset value, it indicates that the humidity is high at this time, and condensation and ice problems are likely to occur. In this regard, the embodiment of the present application can control the start-up of the drawer fan to strengthen the turbulence around the storage drawer, thereby accelerating the evaporation of water vapor and reducing the occurrence of condensation or ice. Therefore, the embodiment of the present application does not need to add an integrated barrel sealing and insulation structure, and can also solve the condensation or ice problems caused by the high refrigeration humidity of the dual-system refrigerator at a low cost.

[0069] 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 the peripheral position of the storage drawer, and collect the humidity value through the humidity sensor.

[0070] 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.

[0071] 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.

[0072] In addition, if Figure 6 As shown, Figure 6 This application Figure 5 A sub-flowchart of step S510 in FIG. 5 ; regarding the above step S510, it may include but is not limited to step S610 and step S620.

[0073] Step S610, receiving a refrigerator door closing instruction;

[0074] Step S620: activating the humidity sensor to collect the humidity value of the surrounding air of the storage drawer according to the refrigerator door closing instruction.

[0075] 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. The humidity sensor is activated upon receiving the refrigerator door closing instruction 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 drawer fan needs to be controlled to start working.

[0076] 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.

[0077] 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.

[0078] like Figure 7 As shown, Figure 7 This application Figure 5 Another sub-flowchart of step S510 in the above-mentioned step S510; regarding the above-mentioned step S510, it may include but is not limited to step S710 and step S720.

[0079] Step S710, collecting sampled humidity values ​​at multiple times within a preset time period through a humidity sensor;

[0080] 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.

[0081] 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.

[0082] 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 sampled humidity value is n and n is an odd number, the median is the (n+1) / 2th number; when the sampled humidity value 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] It should be noted that the above-mentioned cooling frequency may be preset by the user or the system. The user or the system can set the specific value of the cooling frequency according to their own needs, and the embodiment of the present application does not specifically limit the value of the cooling frequency.

[0087] It is understandable that the refrigeration level of the refrigerator compartment can be increased by extending the refrigeration time, the refrigeration level of the refrigerator compartment can be increased by increasing the refrigeration frequency, the refrigeration level of the refrigerator compartment can be increased by extending the refrigeration time and increasing the refrigeration frequency, 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.

[0088] like Figure 8 As shown, Figure 8 This application Figure 5 A sub-flow chart of step S520 in the refrigerator; the refrigerator is also provided with a refrigeration fan, which is used to make air flow through the interior of the refrigeration chamber and the storage drawer; regarding the control of the drawer fan startup work in the above step S520, it may include but is not limited to step S810 and step S820.

[0089] Step S810, obtaining the current state of the refrigeration fan;

[0090] Step S820: When the refrigeration fan is in the shutdown state, control the drawer fan to start working.

[0091] In one embodiment, for the method of obtaining the current state of the refrigeration fan, an air volume sensor is installed in the refrigeration equipment of the embodiment of the present application, and the exhaust volume of the fan can be monitored in real time. The current state of the refrigeration fan is determined according to the exhaust volume of the refrigeration fan. When the exhaust volume of the refrigeration fan is greater than or equal to the preset exhaust volume, the refrigeration fan is in a working state, and when the exhaust volume of the refrigeration fan is less than the preset exhaust volume, the refrigeration fan is in a stopped state.

[0092] In one embodiment, for the method of obtaining the current state of the refrigeration fan, the embodiment of the present application can detect the current of the refrigeration fan, and determine the current state of the refrigeration fan based on the current of the refrigeration fan. When the current of the refrigeration fan is greater than or equal to a preset current, the refrigeration fan is in a working state, and when the current of the refrigeration fan is less than a preset current, the refrigeration fan is in a stopped state.

[0093] In one embodiment, for the method of obtaining the current state of the refrigeration fan, the embodiment of the present application can detect the rotation speed of the refrigeration fan, and determine the current state of the refrigeration fan according to the rotation speed of the refrigeration fan. When the rotation speed of the refrigeration fan is greater than or equal to the preset rotation speed, the refrigeration fan is in a working state, and when the rotation speed of the refrigeration fan is less than the preset rotation speed, the refrigeration fan is in a stopped state.

[0094] It should be noted that the above-mentioned preset exhaust volume, preset current and preset speed can be preset by the user or the system. The user or the system can set the specific values ​​of the preset exhaust volume, preset current and preset speed according to their own needs. The embodiments of the present application do not specifically limit the values ​​of the preset exhaust volume, preset current and preset speed.

[0095] In one embodiment, a method for obtaining the current state of a refrigeration fan is provided by integrating sensor technology, Internet of Things technology, big data analysis and artificial intelligence algorithms, monitoring the refrigeration fan environment through a management cloud platform, a dynamic environment host and various sensors, identifying various situations occurring during the operation of the refrigeration fan, and determining the current state of the refrigeration fan.

[0096] It should be noted that, with respect to obtaining the current state of the refrigeration fan, in addition to using sensor technology, intelligent monitoring solutions, or other acquisition methods, the embodiments of the present application do not limit the method for obtaining the current state of the refrigeration fan.

[0097] In one embodiment, the refrigeration fan will send cold air to the refrigeration room and the storage drawer through the refrigeration air duct and the drawer air duct respectively, so as to achieve cooling, that is, the refrigeration fan will also play a role in disturbing the air around the storage drawer. Therefore, if the refrigeration fan is in a stopped state at this time, it means that the fluidity of the air around the storage drawer is poor, and condensation or ice will easily occur. In this regard, the embodiment of the present application can start the drawer fan when the refrigeration fan is in a stopped state, thereby strengthening the turbulence around the storage drawer, thereby accelerating the evaporation of water vapor and reducing the occurrence of condensation or ice.

[0098] In one embodiment, after obtaining the current state of the refrigeration fan, the method also includes: when the refrigeration fan is in working state, the refrigeration fan will send cold air to the refrigeration chamber and the storage drawer through the refrigeration air duct and the drawer air duct respectively, that is, the refrigeration fan will also strengthen the turbulence around the storage drawer, thereby accelerating the evaporation of water vapor and reducing the occurrence of condensation or ice; then, in order to reduce the reliability risks such as life span and noise caused by the long-term operation of the drawer fan, the embodiment of the present application can control the drawer fan to stop running at this time.

[0099] In addition, if Fig. 9 As shown, Fig. 9 It is a subsequent flow chart provided by an embodiment of the present application after controlling the start-up of the drawer fan; after controlling the start-up of the drawer fan, the method may also include but is not limited to step S910, step S920 and step S830.

[0100] Step S810, obtaining the cumulative running time of the drawer fan;

[0101] Step S820: When the accumulated running 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;

[0102] Step S830: When the accumulated running 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.

[0103] It is understandable that the above-mentioned preset time may be preset by a user or a system. The user or the system can set a specific value of the preset time, and the embodiment of the present application does not specifically limit the value of the preset time.

[0104] In addition, it is worth noting that with regard to obtaining the cumulative operating time of the drawer fan, the timer starts timing after the drawer fan starts working, and stops timing when the drawer fan stops working, thereby obtaining the cumulative operating time of the drawer fan.

[0105] In one embodiment, the timer starts counting after the drawer fan starts working, stops counting when the drawer fan stops working, and the accumulated time of the timer is reset to zero, and starts counting again when the drawer fan starts working again.

[0106] Specifically, the embodiment of the present application can compare the cumulative running time and the preset time. After the drawer fan is controlled to start working, the cumulative running time of the drawer fan 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, and the refrigerator door may not be closed tightly. Then 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; after the drawer fan is controlled to start working, the humidity has decreased during the period when the cumulative running time of the drawer fan is less than the preset time. 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.
