Description

Technical Field

[0001] This disclosure relates to the technical field of refrigerators, such as to a shelf module for a refrigerator, a refrigerator, and a method for controlling a refrigerator. Background Technology

[0002] As people's living standards continue to improve, refrigerators, as an indispensable household appliance, have received widespread attention for their functionality and user experience. In daily use, users often need to store leftover food that is still at a relatively high temperature in the refrigerator. However, placing hot food directly into the refrigerator's crisper compartment can affect its normal operation.

[0003] Because food itself carries a large amount of heat, its temperature is much higher than the set temperature of the refrigerator compartment. When it enters the refrigerator environment, it rapidly releases heat into the surrounding air, causing the overall temperature of the refrigerator compartment to rise significantly in a short period of time. This results in other stored foods in the refrigerator compartment experiencing unnecessary temperature fluctuations, affecting their preservation effect. Therefore, refrigerators with this technology lack targeted and rapid cooling methods for high-temperature foods, thus impacting the refrigerator's preservation performance.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides a shelf module for a refrigerator, a refrigerator, and a control method for the refrigerator, which can quickly cool down food at high temperatures, avoid drastic fluctuations in temperature and humidity inside the refrigerator, and ensure the freshness of the food.

[0007] According to a first aspect of this disclosure, a shelf module for a refrigerator is provided, disposed in the refrigerator compartment, comprising: The hollow shelf has an internal cavity. The hollow shelf includes a first panel and a second panel. The first panel is used to hold food, and the second panel faces the fast-cooling zone of the refrigerator compartment. The second panel has ventilation holes that are connected to the cavity. The vent pipe has one end connected to the hollow shelf and communicates with the cavity, and the other end connected to the inner wall of the refrigerator body and communicates with the main return air duct of the refrigerator body. The hollow shelf cavity, ventilation holes, and vent pipes together form a local return air channel. When the temperature and humidity collected by the refrigerator's temperature and humidity sensors exceed the corresponding thresholds, the refrigeration system introduces the air from the refrigerator compartment into the main return air channel through the local return air channel to cool and dehumidify the air.

[0008] In some embodiments, the second panel is provided with a plurality of ventilation holes, which are distributed in an array.

[0009] In some embodiments, the ventilation holes are located in the area of ​​the second panel away from the vent pipe.

[0010] According to a second aspect of this disclosure, a refrigerator is provided, comprising: The refrigerator itself is equipped with a refrigeration system; The first aspect of this disclosure provides a shelf module, which is installed in the refrigerator compartment of the refrigerator body. The second panel of the hollow shelf of the shelf module faces the fast cooling zone of the refrigerator compartment. One end of the vent pipe of the shelf module is connected to the inner wall of the refrigerator body and communicates with the main return air channel of the refrigerator body. Temperature and humidity sensors are installed in the refrigerator compartment to detect temperature and humidity. When the temperature and humidity collected by the temperature and humidity sensors exceed the corresponding thresholds, the refrigeration system introduces the air from the refrigerator compartment into the main return air duct through the local return air duct of the shelf module to cool and dehumidify the air.

[0011] In some embodiments, the refrigeration system includes a fan and an evaporator, both of which are located in the main return air duct. When the temperature and humidity collected by the temperature and humidity sensor exceed the corresponding threshold, the fan starts and introduces the air from the refrigerator compartment into the main return air duct through the local return air duct in the shelf module, and drives the air to flow through the evaporator to cool and dehumidify the air.

[0012] In some embodiments, a temperature and humidity sensor is installed in the rapid cooling zone. When the temperature and humidity collected by the temperature and humidity sensor exceed the corresponding threshold, the operating power of the fan is determined by the temperature and humidity collected by the temperature and humidity sensor.

[0013] In some embodiments, the hollow shelf of the shelf module is located in the middle of the height direction of the refrigerator compartment, and a conventional shelf is provided below the hollow shelf. The hollow shelf and the conventional shelf together define a rapid cooling zone.

[0014] According to a third aspect of this disclosure, a control method for a refrigerator is provided, applied to a refrigerator provided according to a second aspect of this disclosure, the control method comprising: Acquire temperature and humidity data from a temperature and humidity sensor; Determine whether the temperature and humidity collected by the temperature and humidity sensor exceed the corresponding threshold. When the temperature and humidity collected by the temperature and humidity sensors exceed the corresponding thresholds, the refrigeration system is controlled to introduce the air from the refrigerator compartment into the main return air duct through the local return air duct of the shelf module to cool and dehumidify the air.

[0015] In some embodiments, when the temperature and humidity collected by the temperature and humidity sensors exceed corresponding thresholds, the refrigeration system is controlled to introduce air from the refrigerator compartment into the main return air duct through the local return air duct of the shelf module to cool and dehumidify the air, including: When the temperature and humidity collected by the temperature and humidity sensor exceed the corresponding threshold, the fan is activated, which introduces the air from the refrigerator compartment into the main return air duct through the local return air duct in the shelf module, and drives the air to flow through the evaporator to cool and dehumidify the air.

[0016] In some embodiments, when the temperature and humidity collected by the temperature and humidity sensor exceed corresponding thresholds, the fan is activated, causing the fan to introduce air from the refrigerator compartment into the main return air duct through the local return air duct in the shelf module, and drive the air to flow through the evaporator, so as to utilize the evaporator to cool and dehumidify the air, including: When the temperature and humidity collected by the temperature and humidity sensor exceed the corresponding threshold, the target operating power of the fan is determined based on the temperature and humidity collected by the temperature and humidity sensor. Start the fan and control it to operate at the target power. The fan will draw air from the refrigerator compartment into the main return air duct through the local return air duct in the storage module and drive the air to flow through the evaporator to cool and dehumidify the air.

[0017] The shelf module, refrigerator, and refrigerator control method for a refrigerator provided in this disclosure can achieve the following technical effects: Because the second panel with ventilation holes in the hollow shelf faces the quick-cooling zone, the hot and humid air surrounding the food in the quick-cooling zone is preferentially drawn into the cavity of the hollow shelf through the ventilation holes and enters the main return air duct through the vent pipe. This localized return air duct prioritizes guiding the hot and humid air from the quick-cooling zone to the refrigeration system for cooling and dehumidification, effectively preventing it from spreading to other areas of the refrigerator compartment. This avoids drastic fluctuations in temperature and humidity within the refrigerator compartment, ensuring the freshness of food in other areas. The cooled, dry air processed by the refrigeration system is then returned to the refrigerator compartment to continue circulating and rapidly cooling the food in the quick-cooling zone. This process is repeated continuously, thus cooling hot food in a timely and efficient manner.

[0021] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0023] Unless otherwise stated, the term "multiple" means two or more.

[0024] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0025] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0026] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0027] like Figures 1 to 4 As shown, this embodiment of the present disclosure provides a shelf module 1 for a refrigerator 100, which is disposed in the refrigerator compartment 201 of the refrigerator 100. The shelf module 1 includes a hollow shelf 11 and a vent pipe 12. The hollow shelf 11 has a cavity 110 inside, and the hollow shelf 11 includes a first panel 111 and a second panel 112. The first panel 111 is used to hold food, and the second panel 112 faces the quick-cooling zone 2011 of the refrigerator compartment 201 in the refrigerator body 2. The second panel 112 is provided with a vent hole 1121, and the vent hole 1121 communicates with the cavity 110.

[0028] One end of the vent pipe 12 is connected to the hollow shelf 11 and communicates with the cavity 110, while the other end is connected to the inner wall 21 of the refrigerator body 2 and communicates with the main return air channel 202 of the refrigerator body 2. The cavity 110 of the hollow shelf 11, the vent 1121, and the vent pipe 12 together constitute a local return air channel. It can be understood that the local return air channel and the main return air channel 202 are connected to form a continuous return air channel. When the temperature and humidity collected by the temperature and humidity sensor 3 of the refrigerator 100 exceed the corresponding threshold, the refrigeration system 22 introduces the air from the refrigerator compartment 201 into the main return air channel 202 through the local return air channel to cool and dehumidify the air. The inner wall 21 of the refrigerator body 2 is provided with an air outlet (not shown in the figure), and the low-temperature dry air processed by the refrigeration system 22 can be returned to the refrigerator compartment 201 through the air outlet.

[0029] In this embodiment, the rapid cooling zone 2011 is a specific area within the refrigerator compartment 201, used to preferentially place high-temperature foods. Since the second panel 112 of the hollow shelf 11, which has ventilation holes 1121, faces the rapid cooling zone 2011, the hot and humid air surrounding the high-temperature foods in the rapid cooling zone 2011 can be preferentially drawn into the cavity 110 of the hollow shelf 11 through the ventilation holes 1121 and enter the main return air channel 202 through the vent pipe 12. This localized return air channel preferentially guides the hot and humid air from the rapid cooling zone 2011 to the refrigeration system 22 for cooling and dehumidification, effectively preventing it from spreading to other areas of the refrigerator compartment 201. This avoids drastic fluctuations in temperature and humidity within the refrigerator compartment 201, ensuring the preservation effect of food in other areas. The low-temperature, dry air processed by the refrigeration system 22 is then returned to the refrigerator compartment 201 to continue participating in the circulating cooling, continuously and rapidly cooling the food in the rapid cooling zone 2011. This process is repeated continuously, thus cooling down hot food in a timely and efficient manner.

[0030] In some embodiments, the second panel 112 is provided with ventilation holes 1121. The array of multiple ventilation holes 1121 can form a uniform air intake distribution on the surface of the second panel 112, ensuring that the hot and humid air in different positions of the rapid cooling zone 2011 is synchronously and evenly drawn into the cavity 110, thereby improving the overall ventilation efficiency of the local return air channel.

[0031] In some embodiments, the vent 1121 is located in the area of ​​the second panel 112 away from the vent pipe 12. This area is close to the outlet of the quick-cooling zone 2011. By setting the vent 1121 in this position, the hot and humid air in the quick-cooling zone 2011 that is about to spread to other areas can be drawn in in time, effectively preventing the hot and humid air from spreading to other areas of the refrigerator compartment 201.

[0032] like Figures 1 to 4As shown, this embodiment of the present disclosure provides a refrigerator 100, which includes a refrigerator body 2, a temperature and humidity sensor 3, and a shelf module 1 provided in the above embodiment. The refrigerator body 2 is provided with a refrigeration system 22, and a main return air duct 202 is provided inside the refrigerator body 2. Some components of the refrigeration system 22 are located in the main return air duct 202. The shelf module 1 is disposed in the refrigerator compartment 201 of the refrigerator body 2. The second panel 112 of the hollow shelf 11 of the shelf module 1 faces the fast cooling zone 2011 of the refrigerator compartment 201. One end of the vent pipe 12 of the shelf module 1 is connected to the inner wall 21 of the refrigerator body 2 and communicates with the main return air duct 202 of the refrigerator body 2. The temperature and humidity sensor 3 is disposed in the refrigerator compartment 201 and is used to detect temperature and humidity. When the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold, the refrigeration system 22 introduces air from the refrigerator compartment 201 into the main return air duct 202 through the local return air duct of the shelf module 1 to cool and dehumidify the air. The inner wall 21 of the refrigerator body 2 is provided with an air outlet (not shown in the figure), and the low-temperature dry air processed by the refrigeration system 22 can be returned to the refrigerator compartment 201 through the air outlet.

[0033] In some embodiments, the refrigeration system 22 includes a fan 221 and an evaporator 222, both of which are located in the main return air duct 202. When the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold, the fan 221 starts, introducing air from the refrigerator compartment 201 into the main return air duct 202 through the local return air duct in the shelf module 1, and driving the air to flow through the evaporator 222, so as to use the evaporator 222 to cool and dehumidify the air.

[0034] Fan 221 acts as an air drive source, driving air to flow across the surface of evaporator 222 located in the main return air duct 202, rapidly cooling the hot and humid air to below the dew point, achieving efficient cooling and condensation dehumidification. The treated low-temperature dry air is then returned to the cold storage compartment 201, effectively reducing the temperature and humidity levels.

[0035] In some embodiments, the temperature and humidity sensor 3 is installed in the rapid cooling zone 2011. When the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold, the operating power of the fan 221 is determined by the temperature and humidity collected by the temperature and humidity sensor 3.

[0036] When the temperature and humidity collected by temperature and humidity sensor 3 exceed corresponding thresholds, the rate of temperature change and the rate of humidity change within a preset time period are detected. A combined rate of change is calculated based on the temperature and humidity rates, and the target operating power of fan 221 is determined based on this combined rate of change. Here, the combined rate of change can be the average of the temperature and humidity rates of change.

[0037] The rapid cooling zone 2011 is where high-temperature foods are concentrated, and temperature and humidity fluctuate drastically. By directly placing temperature and humidity sensors 3 in the rapid cooling zone 2011, changes in temperature and humidity can be accurately captured in real time, ensuring high sensitivity and responsiveness of the control system. The operating power of the fan 221 is dynamically determined based on the temperature and humidity data collected by the temperature and humidity sensors 3 in the rapid cooling zone 2011. An appropriate operating power can be set according to the heat content of the high-temperature foods, ensuring timely and efficient cooling of the foods while avoiding over-cooling and energy waste. This significantly reduces overall energy consumption while improving cooling efficiency, achieving synergistic optimization of energy saving and performance.

[0038] In some embodiments, the hollow shelf 11 of the shelf module 1 is located at the middle of the height direction of the refrigerator compartment 201, and a conventional shelf 23 is provided below the hollow shelf 11. The hollow shelf 11 and the conventional shelf 23 together define the rapid cooling zone 2011. Food with a higher temperature is placed on the conventional shelf 23, thus placing the food with a higher temperature in the rapid cooling zone 2011.

[0039] Setting the hollow shelf 11 too high or too low may cause cold air to be drawn back before it can circulate fully. Placing the hollow shelf 11 in the middle helps to extend the air circulation path within the refrigerator compartment 201, promoting sufficient flow of cold air from the top and bottom to the middle, and improving the uniformity of temperature and humidity distribution within the refrigerator 100. Furthermore, the middle position is the most visually and operationally accessible area within the refrigerator compartment 201. Placing the hollow shelf 11 with its return air function here does not affect the normal use of the upper and lower spaces, and also serves as a functional boundary, naturally dividing the regular storage area above the hollow shelf 11 into the rapid cooling zone 2011 below, achieving scientific zoning and efficient utilization of the storage space.

[0040] In some embodiments, such as Figure 5 As shown, the refrigerator 100 also includes a control device 4. The control device 4 is communicatively connected to the refrigeration system 22. The control device 4 can control the refrigeration system 22 to introduce air from the refrigerator compartment 201 into the main return air duct 202 through the local return air duct of the shelf module 1, so as to cool and dehumidify the air.

[0041] In some embodiments, the refrigeration system 22 includes a fan 221 and an evaporator 222. The control device 4 is communicatively connected to the fan 221. The control device 4 can control the fan 221 to start, so that the fan 221 introduces the air of the refrigerator compartment 201 into the main return air duct 202 through the local return air duct in the shelf module 1, and drives the air to flow through the evaporator 222, so as to use the evaporator 222 to cool and dehumidify the air.

[0042] In some embodiments, the control device 4 is communicatively connected to the temperature and humidity sensor 3. The control device 4 acquires the temperature and humidity collected by the temperature and humidity sensor 3. When the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold, the control device 4 can control the refrigeration system 22 to introduce the air of the refrigerator compartment 201 into the main return air channel 202 through the local return air channel of the shelf module 1 to cool and dehumidify the air.

[0043] In conjunction with the refrigerator 100 provided in this embodiment, this embodiment provides a control method for the refrigerator 100, which can be executed by the refrigerator 100's own control device 4. For example... Figure 6 As shown, the control method includes the following steps: S601, the control device 4 acquires the temperature and humidity collected by the temperature and humidity sensor 3.

[0044] S602, the control device 4 determines whether the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold.

[0045] S603, when the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold, the control device 4 controls the refrigeration system 22 to introduce the air of the refrigerator compartment 201 into the main return air channel 202 through the local return air channel of the shelf module 1, so as to cool and dehumidify the air.

[0046] In this embodiment, temperature and humidity thresholds can be set. The control device 4 determines whether the temperature collected by the temperature and humidity sensor 3 exceeds the temperature threshold and whether the humidity collected by the temperature and humidity sensor 3 exceeds the humidity threshold. When the temperature collected by the temperature and humidity sensor 3 exceeds the temperature threshold and the humidity collected by the temperature and humidity sensor 3 exceeds the humidity threshold, the control device 4 controls the refrigeration system 22 to introduce air from the refrigerator compartment 201 into the main return air duct 202 through the local return air duct of the shelf module 1 to cool and dehumidify the air.

[0047] It is understandable that the inner wall 21 of the refrigerator body 2 is provided with an air outlet, and the low-temperature dry air processed by the refrigeration system 22 can be sent back to the refrigerator compartment 201 through the air outlet.

[0048] In some embodiments, when the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold, the refrigeration system 22 is controlled to introduce the air of the refrigerator compartment 201 into the main return air channel 202 through the local return air channel of the shelf module 1 to cool and dehumidify the air. This includes: when the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold, starting the fan 221, so that the fan 221 introduces the air of the refrigerator compartment 201 into the main return air channel 202 through the local return air channel in the shelf module 1, and drives the air to flow through the evaporator 222 to cool and dehumidify the air using the evaporator 222.

[0049] Fan 221 acts as an air drive source, driving air to flow across the surface of evaporator 222 located in the main return air duct 202, rapidly cooling the hot and humid air to below the dew point, achieving efficient cooling and condensation dehumidification. The treated low-temperature dry air is then returned to the cold storage compartment 201, effectively reducing temperature and humidity.

[0050] This disclosure provides another method for controlling a refrigerator 100, such as... Figure 7 As shown, the control method includes the following steps: S701, the control device 4 acquires the temperature and humidity collected by the temperature and humidity sensor 3.

[0051] S702, the control device 4 determines whether the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold.

[0052] S703, when the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold, the control device 4 starts the fan 221, so that the fan 221 introduces the air of the refrigerator compartment 201 into the main return air channel 202 through the local return air channel in the storage module 1, and drives the air to flow through the evaporator 222, so as to use the evaporator 222 to cool and dehumidify the air.

[0053] In some embodiments, the temperature and humidity sensor 3 is located in the rapid cooling zone 2011. When the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold, the fan 221 is activated, causing the fan 221 to introduce air from the refrigerator compartment 201 into the main return air channel 202 through the local return air channel in the shelf module 1, and drive the air to flow through the evaporator 222, so as to use the evaporator 222 to cool and dehumidify the air. This includes: when the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold, determining the target operating power of the fan 221 based on the temperature and humidity collected by the temperature and humidity sensor 3; activating the fan 221 and controlling the fan 221 to operate at the target operating power, causing the fan 221 to introduce air from the refrigerator compartment 201 into the main return air channel 202 through the local return air channel in the shelf module 1, and driving the air to flow through the evaporator 222, so as to use the evaporator 222 to cool and dehumidify the air.

[0054] The rapid cooling zone 2011 is where high-temperature foods are concentrated, and temperature and humidity fluctuate drastically. By directly placing temperature and humidity sensors 3 in the rapid cooling zone 2011, changes in temperature and humidity can be accurately captured in real time, ensuring high sensitivity and responsiveness of the control system. The operating power of the fan 221 is dynamically determined based on the temperature and humidity data collected by the temperature and humidity sensors 3 in the rapid cooling zone 2011. An appropriate operating power can be set according to the heat content of the high-temperature foods, ensuring timely and efficient cooling of the foods while avoiding over-cooling and energy waste. This significantly reduces overall energy consumption while improving cooling efficiency, achieving synergistic optimization of energy saving and performance.

[0055] This disclosure provides another method for controlling a refrigerator 100, such as... Figure 8 As shown, the control method includes the following steps: S801, the control device 4 acquires the temperature and humidity collected by the temperature and humidity sensor 3.

[0056] S802, the control device 4 determines whether the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold.

[0057] S803, when the temperature and humidity collected by the temperature and humidity sensor 3 exceed the corresponding threshold, the control device 4 determines the target operating power of the fan 221 based on the temperature and humidity collected by the temperature and humidity sensor 3.

[0058] S804, the control device 4 starts the fan 221 and controls the fan 221 to operate at the target working power, so that the fan 221 introduces the air of the refrigerator compartment 201 into the main return air channel 202 through the local return air channel in the storage module 1, and drives the air to flow through the evaporator 222, so as to use the evaporator 222 to cool and dehumidify the air.

[0059] In some embodiments, when the temperature and humidity collected by the temperature and humidity sensor 3 exceed corresponding thresholds, the rate of temperature change and the rate of humidity change within a preset time period are detected. A combined rate of change is calculated based on the temperature and humidity rates, and the target operating power of the fan 221 is determined based on the combined rate of change.

[0060] Here, the combined rate of change can be the average of the rate of change of temperature and the rate of change of humidity. When the combined rate of change is high, it indicates that a large amount of hot and humid food has been placed in, and the heat load is increasing rapidly. A higher target operating power is set to quickly establish negative pressure, and the hot and humid air is drawn into the main return air duct through the local return air duct to prevent it from spreading to other areas of the refrigerator compartment. When the combined rate of change is low, a lower target operating power is set to maintain stable cooling and avoid energy consumption and noise problems caused by frequent start-stop operations.

[0061] Combination Figure 9 As shown, the control device 4 of the refrigerator 100 provided in this embodiment includes a processor 41 and a memory 42. Optionally, the outdoor electronic control unit 4 may further include a communication interface 43 and a bus 44.

[0062] Furthermore, the logical instructions in the aforementioned memory 42 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium.
