Description

Technical Field

[0001] The present application relates to the technical field of direct-cooling refrigerators, for example, to a control method and device for a direct-cooling refrigerator, and a direct-cooling refrigerator. Background Art

[0002] Currently, direct-cooling refrigerators are widely used in daily life and supermarket sales because of their function of refrigerating and preserving food materials and other items. A direct-cooling refrigerator usually cools the interior of the refrigerating compartment by surrounding the evaporator coil around the outer wall of the refrigerating compartment. This design will cause the temperature in the area close to the side wall of the refrigerating compartment to be relatively low. When storing fruits and vegetables in the refrigerating compartment close to the rear side wall of the refrigerating compartment, the food materials are likely to be frostbitten, affecting the fresh-keeping effect of the food materials.

[0003] There is a refrigerator in the related art, which is characterized in that it includes: a refrigerating compartment and a partition; the partition is made of a fat material, foot pads are provided at the four corners of the partition, and clips are provided on the front of the partition. When in use, the clips are clamped on the partition and the partition is pushed into the refrigerating compartment, so as to play the role of hanging, fixing the partition and isolating the partition from the inner wall of the refrigerating compartment, effectively preventing the problem of frostbite caused by vegetables and fruits being placed too close to the inner wall of the refrigerator refrigerating compartment.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] The freezing positions at different distances from the rear wall of the refrigerating compartment are different for the temperature of the rear wall of the refrigerating compartment. When the temperature of the rear wall of the refrigerating compartment changes, it is difficult to adjust the position of the partition in time, resulting in a relatively high risk of frostbite for the food materials, and the partition occupies a relatively large amount of space in the refrigerating compartment, affecting the storage capacity of the food materials in the refrigerating compartment.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present application, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0043] Combined Figure 1 and Figure 2 As shown in

[0044] In some embodiments, the direct-cooling refrigerator includes: a box body 300 and a net 400. A refrigerating compartment 310 is provided inside the box body 300, and the net 400 is movably arranged in the rear side wall area of the refrigerating compartment 310, and the net 400 can move towards or away from the rear side wall of the refrigerating compartment 310. In this way, by arranging the net 400 on the rear side wall of the refrigerating compartment 310 to block the food materials, the food materials are prevented from directly touching the rear side wall of the refrigerating compartment 310, and the risk of the food materials being frozen is reduced.

[0045] Optionally, the evaporator coil 320 of the direct-cooling refrigerator is arranged on the rear side wall of the refrigerating compartment 310.

[0046] Optionally, along the direction perpendicular to the rear side wall of the refrigerating compartment 310, the projection of the net 400 blocks the rear side wall of the refrigerating compartment 310. In this way, the net 400 can completely block the rear side wall of the refrigerating compartment 310, preventing the food materials in the refrigerating compartment 310 from directly touching the rear side wall of the refrigerating compartment 310, and reducing the risk of the food materials being frozen.

[0047] Optionally, a guiding hole is provided on the rear sidewall of the refrigerating compartment 310. A guide rail 330 is arranged on one side of the guiding hole. A connecting rod 410 extending towards the rear sidewall of the refrigerating compartment 310 is provided on the sidewall of the netting 400. The connecting rod 410 extends into the guide rail 330 along the guiding hole and is limited to slide within the guide rail 330. In this way, by providing the cooperation of the guide rail 330 and the guiding hole, the connecting rod 410 of the netting 400 is supported and guided, so that the netting 400 can stably move towards or away from the rear sidewall of the refrigerating compartment 310.

[0048] Optionally, a driving motor 500 is arranged on one side of the guide rail 330. A rack is provided on the sidewall of the connecting rod 410. The output end of the driving motor 500 meshes with the rack. In this way, the connecting rod 410 is driven to move by the driving motor 500, so as to drive the netting 400 to move towards or away from the rear sidewall of the refrigerating compartment 310, and the distance between the netting 400 and the rear sidewall of the refrigerating compartment 310 is adjusted.

[0049] It can be understood that the driving motor 500 is controlled by the processor of the direct-cooling refrigerator.

[0050] Optionally, a plurality of guiding holes are provided on the rear sidewall of the refrigerating compartment 310. A guide rail 330 is arranged on one side of each guiding hole. A plurality of connecting rods 410 are provided on the sidewall of the netting 400. Each connecting rod 410 correspondingly extends into the guide rail 330 on one side of a guiding hole. In this way, by providing the cooperation of a plurality of connecting rods 410 and guide rails 330, the stability of the support and guidance of the netting 400 is improved, and the risk of the netting 400 tilting during the movement is reduced.

[0051] Combined with Figure 3 As shown, in one embodiment, a control method for a direct-cooling refrigerator includes:

[0052] S01, the processor obtains the temperature of the rear sidewall of the refrigerating compartment;

[0053] S02, the processor determines the target movement position of the netting according to the temperature of the rear sidewall of the refrigerating compartment;

[0054] S03, the processor controls the netting to move to the target movement position to form an obstruction to the food in the refrigerating compartment.

[0055] By adopting the control method for the direct-cooling refrigerator provided by the embodiments of the present disclosure, an obstruction is formed to the food by arranging a netting on the rear sidewall of the refrigerating compartment, so as to prevent the food from directly touching the rear sidewall of the refrigerating compartment and reduce the risk of the food being frozen. Since the temperature of the rear sidewall of the refrigerating compartment is different and the positions where the food is easily frozen also vary, by obtaining the temperature of the rear sidewall of the refrigerating compartment and controlling the movement position of the netting according to the temperature of the rear sidewall of the refrigerating compartment, while using the netting to obstruct the food to reduce its freezing risk, the influence of the netting on the storage space of the refrigerating compartment is reduced, and the space utilization rate of the refrigerating compartment is improved.

[0056] Optionally, the processor controls the net movement to the target movement position, including: the processor determines the target driving stroke of the driving motor according to the target movement position of the net; the processor controls the driving motor to rotate the target driving stroke so that the net moves to the target movement position. In this way, since the movement of the net is driven by the driving motor, the processor determines the target driving stroke of the driving motor according to the target movement position of the net to control the driving motor, thereby controlling the net to move to the desired position, blocking the food ingredients, and making the net move to the target movement position more accurately.

[0057] Exemplarily, different movement positions correspond to different driving strokes, and the corresponding relationship between the movement position and the driving stroke is preset in the database of the processor. When the processor determines the target movement position, it determines the target driving stroke of the driving motor according to the corresponding relationship between the target movement position and the target driving stroke.

[0058] It can be understood that the driving stroke of the driving motor is controlled by a travel switch. The control of the driving stroke of the driving motor by the processor is essentially to control the driving motor by controlling the travel switch, which will not be elaborated here.

[0059] Optionally, the processor determines the target movement position of the net according to the temperature of the rear side wall of the refrigerated compartment, including: the processor determines the target temperature range in which the temperature of the rear side wall of the refrigerated compartment is located; the processor determines the target movement position of the net according to the corresponding relationship between the target temperature range and the movement position of the net. In this way, when the temperature of the rear side wall of the refrigerated compartment does not vary much, the difference in the ice formation position from the rear side wall of the refrigerated compartment is also not significant. To simplify the control logic and improve the control efficiency, the processor controls the movement position of the net by determining the temperature range in which the temperature of the rear side wall of the refrigerated compartment is located, making the control of the net more efficient, while reducing the risk of food ingredient frostbite and improving the control efficiency.

[0060] Optionally, the processor determines the target active position of the barrier according to the correspondence between the target temperature range and the active position of the barrier, including: when the target temperature range is the first temperature range, the processor determines the target active position of the barrier as the first position; when the target temperature range is the second temperature range, the processor determines the target active position of the barrier as the second position; wherein, the maximum value in the first temperature range is less than the minimum value in the second temperature range, and the distance between the barrier and the rear side wall of the refrigerating compartment when the barrier is in the first position is greater than the distance between the barrier and the rear side wall of the refrigerating compartment when the barrier is in the second position. In this way, when the temperature of the rear side wall of the refrigerating compartment is in the relatively small first temperature range, at this time the temperature of the rear side wall of the refrigerating compartment is relatively low, and the icing distance from the rear side wall of the refrigerating compartment is relatively far, so the processor determines the active position of the barrier as the first position which is relatively far from the rear side wall of the refrigerating compartment. When the temperature of the rear side wall of the refrigerating compartment is in the relatively large second temperature range, at this time the temperature of the rear side wall of the refrigerating compartment is relatively high, and the icing distance from the rear side wall of the refrigerating compartment is relatively close, so the processor determines the active position of the barrier as the second position which is relatively close to the rear side wall of the refrigerating compartment. By adopting the above control logic, the active position of the barrier is matched with the temperature of the rear side wall of the refrigerating compartment, reducing the risk of ingredient frostbite while minimizing the occupancy of the internal space of the refrigerating compartment by the barrier.

[0061] Exemplarily, the first temperature range is an interval greater than or equal to -5°C and less than -1°C, the second temperature range is an interval greater than or equal to -1°C and less than or equal to 2°C, the barrier is 10 centimeters away from the rear side wall of the refrigerating compartment when in the first position, and the barrier is 5 centimeters away from the rear side wall of the refrigerating compartment when in the second position. When the temperature of the rear side wall of the refrigerating compartment is -3°C, the barrier is controlled to move to a position 10 centimeters away from the rear side wall of the refrigerating compartment.

[0062] It can be understood that the distance between the barrier and the rear side wall of the refrigerating compartment refers to the distance between the plane where the barrier is located and the plane where the rear side wall of the refrigerating compartment is located in the direction perpendicular to the plane where the rear side wall of the refrigerating compartment is located.

[0063] Multiple temperature ranges and the corresponding barrier active positions for each temperature range can also be preset in the database of the processor. The barrier active position corresponding to the temperature range with a relatively higher temperature value is relatively closer to the rear side wall of the refrigerating compartment, and the barrier active position corresponding to the temperature range with a relatively lower temperature value is relatively farther from the rear side wall of the refrigerating compartment. The processor further controls the active position of the barrier according to the temperature range in which the temperature of the rear side wall of the refrigerating compartment is located.

[0064] In a specific embodiment, the processor obtains the temperature of the rear side wall of the refrigerating compartment, including: the processor obtains the current gear position of the direct-cooling refrigerator; the processor determines the temperature of the rear side wall of the refrigerating compartment according to the current gear position of the direct-cooling refrigerator. In this way, when the direct-cooling refrigerator is in different gear positions, there are differences in the refrigeration capacity, and there are also differences reflected in the temperature of the rear side wall of the refrigerating compartment. The processor determines the temperature of the rear side wall of the refrigerating compartment according to the current gear position of the direct-cooling refrigerator, and the obtained temperature value can better reflect the current temperature situation of the refrigerating compartment, without the need to set components such as sensors for acquisition, and the cost is relatively low.

[0065] Exemplarily, the direct-cooling refrigerator has multiple refrigeration gear positions, and there is a corresponding temperature of the rear side wall of the refrigerating compartment under each gear position. There is a preset binding relationship between the gear position and the temperature of the rear side wall of the refrigerating compartment. When the processor determines the current gear position of the direct-cooling refrigerator, it determines the temperature of the rear side wall of the refrigerating compartment under this gear position according to the binding relationship between the gear position and the temperature of the rear side wall of the refrigerating compartment.

[0066] The processor can obtain the current gear position of the direct-cooling refrigerator by obtaining parameters such as the operating frequency of the compressor and the input voltage of the compressor, which will not be elaborated here.

[0067] In another specific embodiment, the processor obtains the temperature of the rear side wall of the refrigerating compartment, including: the processor obtains the temperature sent by the temperature sensor arranged on the rear side wall of the refrigerating compartment. In this way, by arranging a temperature sensor on the rear side wall of the refrigerating compartment, the processor determines the temperature of the rear side wall of the refrigerating compartment by obtaining the temperature value sent by the temperature sensor, and the obtained temperature value is more accurate, so as to adjust the position of the barrier net more precisely according to the temperature value.

[0068] Combined with Figure 4 As shown in the figure, in another embodiment, a control method for a direct-cooling refrigerator includes:

[0069] S04, the processor obtains the power-on duration of the direct-cooling refrigerator;

[0070] S05, the processor determines that the power-on duration is greater than or equal to the set power-on duration;

[0071] S01, the processor obtains the temperature of the rear side wall of the refrigerating compartment;

[0072] S02, the processor determines the target moving position of the barrier net according to the temperature of the rear side wall of the refrigerating compartment;

[0073] S03, the processor controls the barrier net to move to the target moving position to form a barrier to the food in the refrigerating compartment.

[0074] Using the control method for a direct-cooling refrigerator provided by the embodiments of the present disclosure, since the temperature of the rear side wall of the refrigerating compartment is unstable when the direct-cooling refrigerator is just started and operated, the processor first obtains the startup duration of the direct-cooling refrigerator before obtaining the temperature of the rear side wall of the refrigerating compartment. When the startup duration is greater than or equal to the set duration, at this time the direct-cooling refrigerator is in a steady-state operation, and then the temperature of the rear side wall of the refrigerating compartment is obtained to control the position of the barrier net, reducing the risk of incorrect control of the barrier net.

[0075] Optionally, when the startup duration is less than the set duration, the processor controls the barrier net to move towards the rear side wall of the refrigerating compartment to the minimum distance. In this way, when the startup duration is less than the set duration, at this time the operating state of the direct-cooling refrigerator is not yet stable, and the temperature of the rear side wall of the refrigerating compartment is relatively high. Even when the food is close to the rear side wall of the refrigerating compartment, the risk of food freezing is relatively low. Therefore, the processor controls the barrier net to move towards the rear side wall of the refrigerating compartment to the minimum distance, making the barrier net close to the rear side wall of the refrigerating compartment and increasing the storage capacity of the refrigerating compartment.

[0076] It can be understood that controlling the barrier net to move towards the rear side wall of the refrigerating compartment to the minimum distance means the maximum limit that the barrier net can move towards the rear side wall of the refrigerating compartment. At this time, the distance between the barrier net and the rear side wall of the refrigerating compartment is the smallest.

[0077] Optionally, the set duration is 5 hours. In this way, when the direct-cooling refrigerator operates for 5 hours, at this time it is considered that the direct-cooling refrigerator is in a steady-state operation state.

[0078] Combined with Figure 5 As shown, in another embodiment, the control method for a direct-cooling refrigerator includes:

[0079] S06, the processor obtains the gear shift duration of the direct-cooling refrigerator;

[0080] S07, the processor determines that the gear shift duration is greater than or equal to the set shift duration;

[0081] S01, the processor obtains the temperature of the rear side wall of the refrigerating compartment;

[0082] S02, the processor determines the target movement position of the barrier net according to the temperature of the rear side wall of the refrigerating compartment;

[0083] S03, the processor controls the barrier net to move to the target movement position to block the food in the refrigerating compartment.

[0084] Using the control method for a direct-cooling refrigerator provided by the embodiments of the present disclosure, since the temperature of the rear side wall of the refrigerating compartment changes when the direct-cooling refrigerator just switches gears, the processor first obtains the gear switching duration of the direct-cooling refrigerator before obtaining the temperature of the rear side wall of the refrigerating compartment. When the gear switching duration is greater than or equal to the set switching duration, at this time, the temperature of the rear side wall of the refrigerating compartment tends to be stable, and then the temperature of the rear side wall of the refrigerating compartment is obtained to control the position of the barrier net, and the moving position of the barrier net is controlled more precisely.

[0085] Optionally, when the processor determines that the gear switching duration is less than the set switching duration, it obtains the change in the temperature of the rear side wall of the refrigerating compartment; when the temperature of the rear side wall of the refrigerating compartment drops, the processor controls the barrier net to move away from the rear side wall of the refrigerating compartment to the maximum distance; when the temperature of the rear side wall of the refrigerating compartment rises, the processor controls the position of the barrier net to remain unchanged. In this way, since the temperature of the rear side wall of the refrigerating compartment changes when the refrigeration gear of the direct-cooling refrigerator is switched, when the temperature of the rear side wall of the refrigerating compartment drops, the current position of the barrier net at this time will increase the risk of foodstuff frostbite. Therefore, the barrier net is controlled to move away from the rear side wall of the refrigerating compartment to the maximum distance to reduce the risk of foodstuff frostbite. When the temperature of the rear side wall of the refrigerating compartment rises, the current position of the barrier net at this time can better reduce the risk of foodstuff frostbite. Since it is unknown to what level the temperature of the rear side wall of the refrigerating compartment will rise, it is sufficient to keep the position of the barrier net unchanged.

[0086] Optionally, the processor obtains the change in the temperature of the rear side wall of the refrigerating compartment, including: the processor obtains the initial temperature and the end temperature of the rear side wall of the refrigerating compartment per unit time; when the initial temperature is greater than the end temperature, the processor determines that the temperature of the rear side wall of the refrigerating compartment is in a descending state; when the initial temperature is less than the end temperature, the processor determines that the temperature of the rear side wall of the refrigerating compartment is in an ascending state.

[0087] It can be understood that controlling the barrier net to move away from the rear side wall of the refrigerating compartment to the maximum distance means controlling the barrier net to move away from the rear side wall of the refrigerating compartment to the maximum limit, and at this time, the distance between the barrier net and the rear side wall of the refrigerating compartment is the largest.

[0088] Optionally, the set switching duration is 2 hours. In this way, when the gear switching duration of the direct-cooling refrigerator meets 2 hours, the temperature of the rear side wall of the refrigerating compartment can reach a stable state.

[0089] Combined with Figure 6 As shown in, in another embodiment, the control method for a direct-cooling refrigerator includes:
