Description

Technical Field

[0001] This invention relates to the field of refrigeration and freezing technology, and in particular to a refrigerator and its control method. Background Technology

[0002] Currently, refrigerators commonly found on the market generally have two types of drawer designs within the freezer compartment: one uses fixed vertical beams to divide the freezer into multiple drawers, and the other uses large drawers arranged vertically. While the former allows for multi-functional partitioning within the freezer, it's not ideal for storing larger items. The latter, while better suited for storing larger items, is less convenient for retrieving small, delicate foods; placing these at the bottom of the large drawer makes them difficult to access. Furthermore, both types of drawers result in relatively low rapid cooling efficiency for food stored within them, failing to meet user needs. Summary of the Invention

[0003] One objective of the first aspect of this invention is to achieve rapid cooling of the quick-cooling zone without affecting the normal use of the refrigerator and freezer compartments.

[0004] Another objective of the first aspect of this invention is to further improve the rapid cooling efficiency of the rapid cooling zone.

[0005] The second aspect of the present invention is to provide a refrigerator.

[0006] In particular, according to a first aspect of the present invention, the present invention provides a method for controlling a refrigerator, the refrigerator including a cabinet, the cabinet defining a refrigerator compartment and a freezer compartment, the freezer compartment having a quick-cooling zone, and the control method including:

[0007] Obtain the start command to activate rapid cooling mode;

[0008] Obtain the internal temperatures of the refrigerator compartment and the freezer compartment respectively;

[0009] Determine whether the refrigerator and / or freezer compartments require cooling based on their internal temperature.

[0010] If so, refrigerate the refrigerator and freezer compartments that require cooling.

[0011] After cooling the refrigerator and freezer compartments that require cooling, a separate supply of cooling airflow is provided to the rapid cooling zone to cool it.

[0012] Optionally, the steps to determine whether the refrigerator and / or freezer compartments require cooling based on the cooling situation include:

[0013] The internal temperatures of the refrigerator compartment and the freezer compartment were compared with their respective preset start-up temperatures.

[0014] If the internal temperature of the refrigerator compartment is greater than or equal to the start-up temperature of the refrigerator compartment, then it is determined that the refrigerator compartment has a cooling requirement.

[0015] If the internal temperature of the freezer compartment is greater than or equal to the freezer compartment's start-up temperature, then the freezer compartment is confirmed to have a cooling demand.

[0016] Optionally, the steps for refrigerating the refrigerator compartment and freezer compartment that require cooling include:

[0017] When the refrigerator compartment needs cooling, adjust the refrigerator's split air supply device to the fully open position, start the compressor and air supply fan, and open the refrigerator door;

[0018] When the freezer compartment requires cooling, adjust the refrigerator's split air supply device to the fully open position, start the compressor and air supply fan, and close the refrigerator door;

[0019] When both the refrigerator and freezer compartments require cooling, adjust the refrigerator's split air supply device to the fully open position, start the compressor and air supply fan, and open the refrigerator door.

[0020] Optionally, if it is determined from the internal temperature that neither the refrigerator compartment nor the freezer compartment requires refrigeration, a separate supply of cooling airflow can be provided to the rapid cooling zone to refrigerate it.

[0021] Optionally, the step of supplying cooling airflow separately to the rapid cooling zone includes:

[0022] Close the refrigerator door and adjust the refrigerator's air distribution system to the fully closed position.

[0023] Optionally, after the step of supplying cooling airflow separately to the rapid cooling zone, the method further includes:

[0024] Cumulative rapid cooling time in the rapid cooling zone;

[0025] Determine if the rapid cooling time has reached the preset time;

[0026] If so, then turn off the compressor and the blower.

[0027] Optionally, the preset time is 150 min to 210 min.

[0028] Optionally, if the rapid cooling time has not reached the preset time, the following steps are also included:

[0029] Reacquire the internal temperatures of the refrigerator and freezer compartments respectively;

[0030] Determine whether the refrigerator and / or freezer compartments require cooling based on the re-acquired internal temperature.

[0031] If so, refrigerate the refrigerator and freezer compartments that require cooling.

[0032] Optionally, a refrigeration sensor is installed in the refrigerator compartment and a freezing sensor is installed in the freezer compartment; the steps for obtaining the internal temperatures of the refrigerator compartment and the freezer compartment respectively include:

[0033] Obtain the temperature detection value from the refrigeration sensor and use the temperature detection value from the refrigeration sensor as the internal temperature of the refrigeration compartment;

[0034] Obtain the temperature detection value of the freezing sensor and use it as the internal temperature of the freezing compartment.

[0035] According to a second aspect of the present invention, a refrigerator is provided, comprising:

[0036] The cabinet is divided into a refrigerator compartment and a freezer compartment, with a dedicated quick-cooling zone inside the freezer compartment; and

[0037] The controller includes a memory and a processor. The memory stores a control program, which is executed by the processor to implement any of the control methods described above.

[0038] The refrigerator and its control method according to embodiments of the present invention, after obtaining the internal temperatures of the refrigerator compartment and the freezer compartment respectively, determine whether the refrigerator compartment and / or the freezer compartment have a cooling demand. If the refrigerator compartment and / or the freezer compartment have a cooling demand, cooling is first applied to the refrigerator compartment and the freezer compartment with the cooling demand. After the cooling of the refrigerator compartment and the freezer compartment with the cooling demand is completed, cooling airflow is supplied separately to the quick-cooling zone to cool the quick-cooling zone. In this way, rapid cooling of food in the quick-cooling zone can be achieved without affecting the normal use of the refrigerator compartment and the freezer compartment.

[0039] Furthermore, the refrigerator and its control method according to this embodiment of the invention, by employing a branched air supply device, can first adjust the branched air supply device to the fully open state when there is a cooling demand in the refrigerator compartment and / or freezer compartment, thereby cooling the refrigerator compartment and freezer compartment that require cooling, while also cooling the quick-cooling zone, eliminating the need for waiting, shortening the time required for quick cooling, and improving quick-cooling efficiency. Since the quick-cooling zone is located inside the freezer compartment, supplying cooling DC to both the freezer compartment and the quick-cooling zone simultaneously will not affect the normal cooling rate of the freezer compartment.

[0049] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0050] Figure 1 This is a schematic diagram of the structure of a refrigerator 10 according to an embodiment of the present invention, with reference to... Figure 1The interior of the cabinet 100 is defined by a refrigerator compartment 110 and a freezer compartment 120. Both the refrigerator compartment 110 and the freezer compartment 120 adopt a double-door structure, and bottle holders are provided on the inner side of the double doors for storing small and delicate food items. The freezer compartment 120 has a rapid cooling zone 130. In this embodiment, the rapid cooling zone 130 can be two rapid cooling drawers arranged side-by-side inside the freezer compartment 120. The rapid cooling drawers are relatively small and can be used to store small and delicate food items. The rapid cooling drawers are isolated from the internal space of the freezer compartment 120 by a sealing structure, allowing for rapid cooling of the food placed inside. The freezer compartment 120 also has two larger freezer drawers arranged vertically inside, which can be used to store larger food items.

[0051] The refrigeration system may include a compressor, a condenser, a capillary tube, and an evaporator, configured to generate cooling capacity in a controlled manner to maintain the internal temperature of the refrigerator compartment 110, the freezer compartment 120, and the quick-cooling zone 130. Since the operating principles of the refrigeration system are well known to those skilled in the art, they will not be described in detail here.

[0052] Figure 2 This is an exploded view of a branched air supply device 200 according to an embodiment of the present invention. Figure 3 This is a schematic diagram of the front side of the air duct rear cover 220 according to an embodiment of the present invention. Figure 4 This is a schematic diagram showing the positional relationship of the duct back cover 220, the air supply fan 230, and the adjusting component 240 when the branched air supply device 200 is in the fully closed state according to an embodiment of the present invention.

[0053] Reference Figures 2 to 4 The branched air supply device 200 can be installed on the back side of the freezer compartment 120, and includes at least a front cover 210, a rear cover 220, a blower 230, and an adjusting member 240. The front cover 210 and the rear cover 220 are interlocked. The blower 230 is installed at the air inlet of the rear cover 220. The rear cover 220 forms a refrigeration air outlet 221, a freezer air outlet 222, and a rapid cooling air outlet 223 around the blower 230. The adjusting member 240 covers the blower 230 and is configured such that when rotated to the fully open state, the refrigeration air outlet 221, the freezer air outlet 222, and the rapid cooling air outlet 223 are exposed; when rotated to the fully closed state, the refrigeration air outlet 221 and the freezer air outlet 222 are covered. In other words, the adjusting component 240 will not block the rapid cooling air outlet 223 in either the fully open or fully closed state.

[0054] In practical applications, after the user selects the rapid cooling mode, if both the refrigerator compartment 110 and the freezer compartment 120 require cooling, the adjusting component 240 can be turned to the fully open position to start the compressor and the air blower 230, thereby supplying cooling airflow to the refrigerator compartment 110 and the freezer compartment 120 to ensure normal cooling in both compartments. After the refrigerator compartment 110 and the freezer compartment 120 have finished cooling, the adjusting component 240 can be turned to the fully closed position to cool the rapid cooling zone 130 separately. It can be understood that during the cooling process of the refrigerator compartment 110 and the freezer compartment 120, although the branch air supply device 200 also supplies cooling airflow to the rapid cooling zone 130 through the rapid cooling air outlet 223, the rapid cooling zone 130 is located inside the freezer compartment 120 and therefore does not essentially reduce the cooling rate of the freezer compartment 120.

[0055] Considering that if only the freezer compartment 120 requires cooling after the user selects the quick-cooling mode, turning the adjustment component 240 to the fully open position and starting the compressor and blower fan 230 would result in excessive refrigerant airflow being introduced into the refrigerator compartment 110, causing low internal temperature and humidity in the refrigerator compartment 110 and affecting its normal operation. Therefore, to solve this problem, the refrigerator compartment 110 in this embodiment is also equipped with a separate refrigerant air damper. Refrigerant airflow can only be supplied to the refrigerator compartment 110 when the refrigerant air damper is open.

[0056] Figure 5 This is a structural block diagram of a refrigerator 10 according to an embodiment of the present invention, with reference to... Figure 5 The refrigerator 10 also includes a controller 300, which includes a memory 320 and a processor 310. The memory 320 stores a control program 321. When the controller 300 is executed by the processor 310, it is used to implement the control method of the refrigerator 10 in any of the following embodiments.

[0057] Figure 6 This is a schematic diagram of a control method for a refrigerator 10 according to an embodiment of the present invention, with reference to... Figure 4 The control method of the refrigerator 10 includes at least the following steps S102 to S110.

[0058] Step S102: Obtain the start command to enable the rapid cooling mode.

[0059] Step S104: Obtain the internal temperatures of the refrigerator compartment 110 and the freezer compartment 120 respectively.

[0060] Step S106: Determine whether the refrigerator compartment 110 and / or freezer compartment 120 have a cooling requirement based on the internal temperature.

[0061] Step S108: If so, refrigerate the refrigerator compartment 110 and the freezer compartment 120 that require refrigeration.

[0062] In step S110, after the refrigerator compartment 110 and the freezer compartment 120, which have cooling requirements, have completed cooling, a separate cooling airflow is supplied to the rapid cooling zone 130 to cool the rapid cooling zone 130.

[0063] The control method of the refrigerator 10 in this embodiment of the invention, after acquiring the internal temperatures of the refrigerator compartment 110 and the freezer compartment 120, determines whether the refrigerator compartment 110 and / or the freezer compartment 120 have a cooling requirement. If the refrigerator compartment 110 and / or the freezer compartment 120 have a cooling requirement, the refrigerator compartment 110 and the freezer compartment 120 with the cooling requirement are cooled first. After the refrigerator compartment 110 and the freezer compartment 120 with the cooling requirement are cooled, a separate cooling airflow is supplied to the quick-cooling zone 130 to cool the quick-cooling zone 130. In this way, rapid cooling of food in the quick-cooling zone 130 can be achieved without affecting the normal use of the refrigerator compartment 110 and the freezer compartment 120.

[0064] A refrigerator 10 has a refrigerator sensor installed in its refrigerator compartment 110 and a freezer sensor installed in its freezer compartment 120. The steps for obtaining the internal temperatures of the refrigerator compartment 110 and the freezer compartment 120 can be as follows: obtain the temperature detection value of the refrigerator sensor and use it as the internal temperature of the refrigerator compartment 110; obtain the temperature detection value of the freezer sensor and use it as the internal temperature of the freezer compartment 120.

[0065] In this embodiment, the step of determining whether the refrigerator compartment 110 and / or the freezer compartment 120 have a cooling requirement based on the internal temperature can be to compare the internal temperature of the refrigerator compartment 110 and the freezer compartment 120 with their respective preset start-up temperature. If the internal temperature of the refrigerator compartment 110 is greater than or equal to the start-up temperature of the refrigerator compartment 110, then it is determined that the refrigerator compartment 110 has a cooling requirement. If the internal temperature of the freezer compartment 120 is greater than or equal to the start-up temperature of the freezer compartment 120, then it is determined that the freezer compartment 120 has a cooling requirement.

[0066] The following situations require cooling: 1. Refrigerator compartment 110 requires cooling, but freezer compartment 120 does not. 2. Refrigerator compartment 110 requires cooling, but freezer compartment 120 does not. 3. Both refrigerator compartment 110 and freezer compartment 120 require cooling. To achieve higher technical performance for refrigerator 10, the above steps can be further optimized and configured, which will be described in detail based on the three situations described above.

[0067] Scenario 1: When the refrigerator compartment 110 requires cooling but the freezer compartment 120 does not, the steps to cool both compartments are as follows: First, adjust the refrigerator 10's branch air supply device 200 to the fully open position. Then, start the compressor and the blower 230, and finally open the refrigerator air door. Since the freezer compartment 120 recovers temperature faster, supplying cooling air to both the refrigerator and freezer compartments simultaneously can maintain the internal temperature of the freezer compartment 120.

[0068] Scenario 2: When the refrigerator compartment 110 does not require cooling but does require cooling, the steps to cool the refrigerator compartment 110 and freezer compartment 120 can be as follows: adjust the branch air supply device 200 of the refrigerator 10 to the fully open state, then start the compressor and the air blower 230, and then close the refrigerator air damper. Since the refrigerator compartment 110 does not require cooling, closing the refrigerator air damper can prevent excessive refrigerant airflow from entering the refrigerator compartment 110, thus avoiding low internal temperature and humidity in the refrigerator compartment 110 and affecting its normal use.

[0069] Scenario 3: When both the refrigerator compartment 110 and the freezer compartment 120 have a cooling requirement, the steps to cool the refrigerator compartment 110 and the freezer compartment 120 can be as follows: first, adjust the branch air supply device 200 of the refrigerator 10 to the fully open state, then start the compressor and the air supply fan 230, and then open the refrigerator door to cool the refrigerator compartment 110 and the freezer compartment 120 at the same time.

[0070] The above describes the specific steps for cooling the refrigerator compartment 110 and / or freezer compartment 120 when there is a cooling requirement. When neither the refrigerator compartment 110 nor the freezer compartment 120 requires cooling, a cooling airflow is directly supplied to the rapid cooling zone 130 to quickly cool it.

[0071] The step of supplying cooling airflow to the quick-cooling zone 130 separately can be to close the refrigerator door and adjust the branch air supply device 200 of the refrigerator 10 to a fully closed state, so as to supply cooling airflow only to the quick-cooling zone 130 and achieve rapid cooling of the quick-cooling zone 130.

[0072] After supplying cooling airflow to the rapid cooling zone 130 separately, the rapid cooling time of the rapid cooling zone 130 can be accumulated, and then it can be determined whether the rapid cooling time has reached the preset time. If so, the compressor and the blower 230 are turned off; if not, the cooling airflow is continued to be supplied to the rapid cooling zone 130.

[0073] In this embodiment, the preset time can be 150 min to 210 min. Preferably, the preset time is 180 min. Through practical application, it has been found that controlling the supply time of cooling airflow to the rapid cooling zone 130 to around 180 min can achieve a good rapid cooling effect. The rapid cooling efficiency is more than 3 times that of the rapid cooling mode of the traditional refrigerator 10, and the energy consumption of rapid cooling is less than half that of the rapid cooling mode of the traditional refrigerator 10, with particularly significant energy-saving effect.

[0074] Furthermore, if the rapid cooling time has not reached the preset time, the internal temperatures of the refrigerator compartment 110 and the freezer compartment 120 can be re-acquired. Then, based on the re-acquired internal temperatures, it can be determined whether the refrigerator compartment 110 and / or the freezer compartment 120 have a cooling requirement. If so, the refrigerator compartment 110 and the freezer compartment 120 with a cooling requirement are cooled to prevent the refrigerator compartment 110 and the freezer compartment 120 from not being cooled in time during the rapid cooling process, which would affect the normal use of the refrigerator compartment 110 and the freezer compartment 120.

[0075] Furthermore, after the rapid cooling zone 130 is completed, the internal temperatures of the rapid cooling compartment 110 and the freezer compartment 120 can be retrieved again. Then, based on the retrieved internal temperatures, it can be determined whether the refrigerator compartment 110 and / or the freezer compartment 120 have a cooling requirement. If so, the refrigerator compartment 110 and the freezer compartment 120 with a cooling requirement are cooled. If not, the branch air supply device 200 is adjusted to a fully closed state, the refrigerator air damper is closed, the compressor is turned off, and the air supply fan 230 is turned off.

[0076] Figure 7 This is a flowchart of a control method for a refrigerator 10 according to an embodiment of the present invention, with reference to... Figure 7 The control method includes at least the following steps S202 to S230.

[0077] Step S202: Obtain the start command to enable the rapid cooling mode.

[0078] Step S204: Obtain the internal temperature of the refrigerator compartment 110.

[0079] Step S206: Determine whether the internal temperature of the refrigerator compartment 110 is greater than or equal to the start-up temperature of the refrigerator compartment 110. If yes, proceed to step S208; otherwise, proceed to step S214.

[0080] Step S208: Adjust the branch air supply device 200 to the fully open state, start the compressor, start the air supply fan 230, and open the refrigerator air damper.

[0081] Step S210: Determine whether the internal temperature of the refrigerator compartment 110 is less than or equal to the shutdown point temperature of the refrigerator compartment 110. If so, proceed to step S212.

[0082] Step S212: Close the refrigerator door.

[0083] Step S214: Obtain the internal temperature of the freezer compartment 120.

[0084] Step S216: Determine whether the internal temperature of the freezer compartment 120 is greater than or equal to the start-up temperature of the freezer compartment 120. If yes, proceed to step S218; otherwise, proceed to step S222.

[0085] In step S218, if the compressor and the air supply fan 230 are not started at this time, the branch air supply device 200 is first adjusted to the fully open state, and then the compressor and the air supply fan 230 are started; if the compressor and the air supply fan 230 are already started at this time, the compressor and the air supply fan 230 are kept running.

[0086] Step S220: Determine whether the internal temperature of the freezer compartment 120 is less than or equal to the shutdown point temperature of the freezer compartment 120. If so, proceed to step S222.

[0087] Step S222: Adjust the branch air supply device 200 to the fully closed state.

[0088] In step S224, if the compressor and the blower 230 are not started at this time, start the compressor and the blower 230 first; if the compressor and the blower 230 are already started at this time, keep the compressor and the blower 230 running.

[0089] Step S226: Accumulate the rapid cooling time for supplying cooling airflow to the rapid cooling zone 130.

[0090] Step S228: Determine whether the rapid cooling time has reached the preset time. If so, proceed to step S230.

[0091] Step S230: Turn off the compressor and turn off the air blower 230.

[0092] According to any one or a combination of the above optional embodiments, the embodiments of the present invention can achieve the following beneficial effects:

[0093] The refrigerator 10 and its control method of this invention, after acquiring the internal temperatures of the refrigerator compartment 110 and the freezer compartment 120, determine whether the refrigerator compartment 110 and / or the freezer compartment 120 have a cooling requirement. If the refrigerator compartment 110 and / or the freezer compartment 120 have a cooling requirement, the refrigerator compartment 110 and the freezer compartment 120 with the cooling requirement are cooled first. After the refrigerator compartment 110 and the freezer compartment 120 with the cooling requirement are cooled, a separate cooling airflow is supplied to the quick-cooling zone 130 to cool the quick-cooling zone 130. In this way, rapid cooling of food in the quick-cooling zone 130 can be achieved without affecting the normal use of the refrigerator compartment 110 and the freezer compartment 120.

[0094] Furthermore, the refrigerator 10 and its control method in this embodiment of the invention, by employing a branched air supply device 200, can first adjust the branched air supply device 200 to a fully open state when there is a cooling demand in the refrigerator compartment 110 and / or the freezer compartment 120, thereby cooling the refrigerator compartment 110 and the freezer compartment 120 that have cooling demand, while also cooling the quick-cooling zone 130, eliminating the need for waiting, shortening the time required for quick cooling, and improving quick-cooling efficiency. Since the quick-cooling zone 130 is located in the freezer compartment 120, supplying cooling DC to both the freezer compartment 120 and the quick-cooling zone 130 simultaneously will not affect the normal cooling rate of the freezer compartment 120.

[0095] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
