Description

Technical Field

[0001] The present application relates to the technical field of household appliances, for example, to a defrosting control method and device for a refrigeration device, a refrigeration device, and a computer-readable storage medium. Background Art

[0002] A freezer is a household appliance that can lower the internal temperature to provide a low-temperature storage cavity for storing food or ingredients, so as to extend the shelf life of food or ingredients. A freezer generally includes a cabinet, a refrigeration system, and a control system. During the flow of the refrigerant, heat exchange between the storage cavity of the freezer and the external environment can be completed through evaporation and condensation, etc., so as to ensure that the storage cavity is in a low-temperature state. However, if the humidity inside the freezer is too high or the sealing performance is not good, it may cause the drain hole to be blocked or the water droplets cannot be discharged smoothly, gradually accumulating on the inner wall or shelves of the freezer, and finally forming frost.

[0003] In the related art, the temperature of the evaporator is detected by a temperature sensor, and the temperature inside the storage cavity is calculated based on the temperature of the evaporator, so as to determine whether frosting occurs inside the storage cavity.

[0004] After the freezer is frosted, defrosting is generally performed through a hot gas defrosting system, that is, the evaporator is temporarily made into a condenser through a solenoid valve, and defrosting is performed with the hot gas generated by the condenser.

[0005] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0006] In the related art, since the temperature inside the storage cavity cannot be detected in time to determine whether frosting occurs in the storage cavity, a fixed defrosting time can only be set. This may lead to incomplete defrosting due to insufficient defrosting time, or affect the refrigeration effect inside the storage cavity due to too long defrosting time, reducing the user experience.

[0007] 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.

[0040] In order to more comprehensively understand the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The attached drawings are only for reference and explanation, and are not used to limit the embodiments of the present disclosure. In the following technical descriptions, for the sake of explanation, numerous details are provided to give a thorough understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be shown in a simplified manner to simplify the drawings.

[0041] In the embodiments of the present disclosure, the terms "first", "second", etc. in the description and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so as to implement the embodiments of the present disclosure described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0042] In the embodiments of the present disclosure, the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "middle", "outer", "front", "rear", etc. is based on the orientation or positional relationship shown in the accompanying drawings. These terms are mainly used to better describe the embodiments of the present disclosure and their implementations, and are not used to limit that the indicated devices, elements or components must have a specific orientation or be constructed and operated in a specific orientation. And, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0043] In addition, the terms "arranged", "connected", "fixed" should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, elements or components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0044] Unless otherwise specified, the term "plurality" means two or more.

[0045] In the embodiments of the present disclosure, the character " / " indicates an "or" relationship between the front and rear objects. For example, A / B means: A or B.

[0046] The term "and / or" is an associative relationship describing an object, indicating that three relationships can exist. For example, A and / or B means: A or B, or, these three relationships of A and B.

[0047] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0048] In the related art, generally, a temperature sensor is arranged at the evaporator of the refrigerator to obtain the temperature of the evaporator. After obtaining the temperature of the evaporator, the temperature sensor can calculate the estimated temperature in the storage cavity through a preset formula, and determine whether frosting occurs in the storage cavity according to the estimated temperature.

[0049] However, the above method cannot detect the temperature in the storage cavity in a timely and accurate manner, and thus cannot accurately judge the specific frosting situation in the storage cavity. Therefore, after judging that frosting occurs in the storage cavity, a fixed defrosting time will be set. At this time, if there are more goods in the storage cavity, the temperature recovery speed of the storage cavity is slower, and the situation of incomplete defrosting may occur; if there are fewer goods in the storage cavity, the temperature recovery speed of the storage cavity is faster, which may affect the refrigeration effect in the storage cavity and the user experience is not good.

[0050] As Figures 1 to 9 shown, the embodiments of the present disclosure provide a defrosting control method and device for a refrigeration device, a refrigeration device, and a computer-readable storage medium, which can timely detect the temperature of the inner container and judge whether the inner container is frosted, so as to avoid the situation of too long or too short defrosting time and improve the user experience.

[0051] As Figures 1 to 6 shown, the embodiments of the present disclosure provide a refrigeration device, including: a box body, a defrosting device, and an inner container 02 temperature sensor. The box body includes an inner container 02; the defrosting device is arranged in the box body for defrosting the inner container 02; the inner container 02 temperature sensor includes a first detection probe arranged in the inner container 02 for obtaining the temperature of the inner container 02. Among them, the inner container 02 temperature sensor is electrically connected to the defrosting device, and the inner container 02 temperature sensor can control the defrosting device to start or stop according to the temperature of the inner container 02.

[0052] Specifically, the defrosting device is fixedly installed at a position corresponding to the inner container 02 of the box body, and is used to defrost the inner container 02 to prevent the inner container 02 from frosting and affecting the refrigeration effect of the refrigeration equipment. The temperature sensor of the inner container 02 is arranged on the box body, and the first detection probe is attached to the inner container 02, so that the temperature of the inner container 02 obtained by the temperature sensor of the inner container 02 is more accurate. After the temperature sensor of the inner container 02 obtains the temperature of the inner container 02, the frosting condition of the inner container 02 can be further judged according to the temperature of the inner container 02, and the defrosting device can be controlled to start or stop according to the frosting condition.

[0053] Optionally, the refrigeration equipment further includes a timer. The timer is electrically connected to the temperature sensor of the inner container 02 and is used to obtain the defrosting cycle. Among them, within the preset defrosting cycle, the temperature sensor of the inner container 02 only controls the defrosting device to start once.

[0054] In practical applications, the preset defrosting cycle can be set according to the actual needs of users. For example, when the defrosting cycle is greater than or equal to 24h, that is, the time since the last defrosting device was started is greater than or equal to 24h, such as the defrosting cycle is 24h, 25h or 26h, and the first temperature T1 of the inner container 02 is greater than or equal to the first preset temperature, the temperature sensor of the inner container 02 controls the defrosting device to start.

[0055] Optionally, the timer can also obtain the defrosting time, and the timer is electrically connected to the defrosting device. When the defrosting time is greater than the preset time, the timer controls the defrosting device to stop. Such a setting can prevent the defrosting time from being too long due to inaccurate detection results of the temperature sensor of the inner container 02, and further prevent the goods stored by users from melting.

[0056] In practical applications, the defrosting time can be set according to the actual needs of users, such as the defrosting time is 25min.

[0057] As Figure 1 shown, in some embodiments, the inner container 02 is provided with a storage cavity 03. The refrigeration equipment further includes: a temperature sensor of the storage cavity 03. The temperature sensor of the storage cavity 03 includes a second detection probe arranged in the storage cavity 03 and is used to obtain the temperature of the storage cavity 03. Among them, the temperature sensor of the storage cavity 03 is electrically connected to the defrosting device. When the defrosting device is started, the temperature sensor of the storage cavity 03 can control the defrosting device to stop according to the temperature in the storage cavity 03.

[0058] Specifically, the user can store items in the storage cavity 03. The second detection head of the temperature sensor of the storage cavity 03 is arranged in the storage cavity 03 to obtain the temperature in the storage cavity 03 in a timely manner. When the defrosting device is turned on, the temperature sensor of the storage cavity 03 can obtain the third temperature T3 of the storage cavity 03. If the third temperature T3 of the storage cavity 03 obtained by the temperature sensor of the storage cavity 03 is less than or equal to the third preset temperature, the temperature sensor of the storage cavity 03 determines that the defrosting is completed and controls the defrosting device to turn off.

[0059] As Figure 2 shown, in some embodiments, an avoidance opening is provided on the side wall surface of the inner container 02; the refrigeration device further includes: a fixed box 20 and a connecting pipe 30. The fixed box 20 is arranged at a position corresponding to the avoidance opening in the interlayer, and includes a connecting cavity 21 communicating with the avoidance opening; the connecting pipe 30 is arranged in the interlayer and communicates with the connecting cavity 21. Among them, the temperature sensor of the storage cavity 03 passes through the connecting pipe 30 and the connecting cavity 21 in sequence, and the second detection probe extends into the storage cavity 03 through the avoidance opening.

[0060] Specifically, the temperature sensor of the storage cavity 03 includes a wire harness and a second detection probe. The wire harness is used to realize the electrical connection between the defrosting device and the second detection probe. The first end of the wire harness is connected to the defrosting device, and the second end passes through the connecting pipe 30 and the connecting cavity 21 in sequence, and extends into the storage cavity 03 through the avoidance opening. Among them, the second detection probe is arranged at the second end of the wire harness so that the second detection probe is located in the storage cavity 03.

[0061] It can be understood that the interlayer is generally filled with foaming material. If the wire harness of the temperature sensor of the storage cavity 03 is directly embedded in the foaming material, it will affect the later maintenance or replacement of the temperature sensor of the storage cavity 03. Therefore, setting the fixed box 20 and the connecting cavity 21 in the interlayer is more convenient for the user to maintain or replace the temperature sensor of the storage cavity 03.

[0062] As Figure 4 and Figure 5 shown, in some embodiments, on the extending path of the temperature sensor of the storage cavity, a guiding surface 22 is provided in the connecting cavity 21. Among them, the guiding direction of the guiding surface 22 is defined as facing the fixed cavity 11.

[0063] Specifically, when installing the temperature sensor of the storage cavity, the temperature sensor of the storage cavity can be inserted into the connecting cavity 21 from the interlayer. After the temperature sensor of the storage cavity is inserted into the connecting cavity 21, the temperature sensor of the storage cavity will contact the guiding surface 22. At this time, the guiding surface 22 can guide the temperature sensor of the storage cavity in the direction facing the fixed cavity 11, so that the temperature sensor of the storage cavity continues to move and is inserted into the fixed cavity 11 through the avoidance opening.

[0064] As Figure 4 and Figure 6As shown, in some embodiments, the refrigeration device further includes: a fixed buckle plate 40. The fixed buckle plate 40 is disposed on the other side of the avoidance opening relative to the fixed box 20. Wherein, the fixed buckle plate 40 can be snapped onto the fixed box 20 so that the fixed buckle plate 40 and the fixed box 20 clamp the inner liner 02.

[0065] Specifically, after the fixed box 20 is installed in the interlayer, the fixed buckle plate 40 can be buckled and snapped onto the fixed box 20 from the storage cavity 03, as Figure 4 shown. Wherein, the sizes of the fixed box 20 and the fixed buckle plate 40 are larger than the size of the avoidance opening. In this way, after the fixed buckle plate 40 is buckled and snapped onto the fixed box 20, the fixed buckle plate 40 and the fixed box 20 can clamp the edge of the avoidance opening to fix the fixed buckle plate 40 and the fixed box 20 on the inner liner 02. At the same time, the fixed buckle plate 40 is connected to the fixed box 20 by a snap connection method, which is more convenient for the user to disassemble the fixed box 20 later and maintain or replace the temperature sensor of the storage cavity 03.

[0066] As Figures 4 to 6 shown, in some embodiments, a snap protrusion 23 is provided on the side wall surface of the connection cavity 21; a snap 41 is provided at a position corresponding to the snap protrusion 23 on the fixed buckle plate 40. Wherein, the snap 41 extends through the avoidance opening to a position corresponding to the snap protrusion 23 so that the snap 41 can be snapped onto the snap protrusion 23.

[0067] Specifically, after the fixed buckle plate 40 is buckled onto the fixed box 20 from the storage cavity 03, the snap 41 of the fixed buckle plate 40 can extend through the avoidance opening to a position corresponding to the snap protrusion 23 and be snapped onto the snap protrusion 23 to prevent the fixed buckle plate 40 from detaching from the fixed box 20, as Figure 4 shown. At the same time, the fixed buckle plate 40 is snapped onto the fixed box 20 by using the snap 41 and the snap protrusion 23, which is more convenient for the user to remove the fixed buckle plate 40 from the fixed box 20.

[0068] As Figure 2 and Figure 3 shown, in some embodiments, the refrigeration device further includes: a fixed seat 10. The fixed seat 10 is disposed at a position corresponding to the second detection probe in the storage cavity 03. Wherein, the fixed seat 10 is provided with a hook 12, and the second detection probe can be snapped onto the hook 12.

[0069] Specifically, the fixed seat 10 is disposed in the storage cavity 03. After the second detection probe extends into the storage cavity 03 through the avoidance opening, the second detection probe can be snapped onto the hook 12 of the fixed seat 10 to fix the second detection probe.

[0070] The fixed seat 10 is arranged at a position corresponding to the avoidance opening in the storage cavity 03, and the fixed seat 10 is arranged in a way that covers the second detection probe, so that the second detection probe is located in the fixed cavity 11, thereby avoiding the second detection probe from contacting the items in the storage cavity 03. A clamping portion is arranged at a position corresponding to the second detection probe in the fixed cavity 11, and the user can clamp the second detection probe of the temperature sensor of the storage cavity 03 to the clamping portion to prevent the second detection probe from shaking.

[0071] It can be understood that making the fixed cavity 11 communicate with the storage cavity 03 can allow the air in the storage cavity 03 to flow into the fixed cavity 11 and reach the second detection probe. With this setting, the second detection probe of the temperature sensor of the storage cavity 03 can directly detect the temperature of the air in the storage cavity 03 to more accurately determine whether frosting occurs in the storage cavity 03.

[0072] Such as Figure 3 As shown, optionally, a ventilation opening 14 is arranged at a position corresponding to the second detection probe on the fixed seat 10, and the ventilation opening 14 is used to communicate the fixed cavity 11 and the storage cavity 03. In this way, the air in the storage cavity 03 can directly flow through the ventilation opening 14 to the second detection probe, so as to further ensure the accuracy of the temperature result obtained by the temperature sensor of the storage cavity 03.

[0073] In some embodiments, a sealing device is arranged in the connection cavity 21 to prevent the cold air in the storage cavity 03 from leaking into the connecting pipe 30.

[0074] Specifically, after clamping the temperature sensor of the storage cavity 03 to the fixed seat 10, the user can install the sealing device in the connection cavity 21 to seal the connection cavity 21. In this way, it is possible to prevent the cold air in the storage cavity 03 from flowing out through the connecting pipe 30 and causing cold leakage, thereby ensuring the refrigeration effect of the refrigeration device.

[0075] Optionally, the sealing device is sealing putty. After clamping the temperature sensor of the storage cavity 03 to the fixed seat 10, the user can press the sealing putty in the connection cavity 21 to make the sealing putty seal the connection cavity 21.

[0076] The connecting pipe 30 is arranged in a form that penetrates the interlayer, and the connecting pipe 30 communicates with the connection cavity 21. When the user installs the temperature sensor of the storage cavity 03, the temperature sensor of the storage cavity 03 can be inserted into the connecting pipe 30 from outside the interlayer and then the temperature sensor of the storage cavity 03 can continue to move and extend into the connection cavity 21. If the user needs to maintain or replace the temperature sensor of the storage cavity 03, the temperature sensor of the storage cavity 03 can be first disengaged from the clamping portion of the fixed cavity 11, and then the temperature sensor of the storage cavity 03 can be directly pulled out from the fixed box 20 and the connecting pipe 30.

[0077] Optionally, the lower wall surface of the connection cavity 21 of the fixed box 20 is inclined to form a diversion surface, and the diversion surface is provided with a diversion opening. Among them, the height of the side of the diversion surface away from the avoidance opening is lower than the height of the side close to the avoidance opening, and the diversion opening is arranged on the side of the diversion surface away from the avoidance opening. In this way, if condensed water is generated in the connection cavity 21, the condensed water can slide to the diversion opening through the diversion surface and flow out of the connection cavity 21 through the diversion opening. Such a setting can prevent the condensed water from accumulating in the connection cavity 21.

[0078] As Figure 4 and Figure 5 shown, optionally, when the connecting pipe 30 is located below the fixed box 20, the connecting pipe 30 extends into the connection cavity 21, and the end of the connecting pipe 30 protrudes from the bottom wall surface of the connection cavity 21 to prevent the condensed water in the connection cavity 21 from flowing into the connecting pipe 30.

[0079] In some embodiments, the distance between the hook 12 and the inner tank 02 is greater than or equal to a preset distance.

[0080] Specifically, a convex portion is provided at the position of the fixed seat 10 corresponding to the temperature sensor of the storage cavity 03, and the convex portion protrudes in a direction away from the fixed box 20 to increase the space of the fixed cavity 11 at this position. The hook 12 is arranged at the position corresponding to the convex portion of the fixed cavity 11 to increase the distance between the hook 12 and the inner tank 02. Such a setting can prevent the inner tank 02 from affecting the detection result of the temperature sensor of the storage cavity 03 if the inner tank 02 frosts.

[0081] In practical applications, the distance between the hook 12 and the inner tank 02 can be set according to the actual needs of the user. For example, the hook 12 is 1 cm, 2 cm or 3 cm away from the inner tank 02.

[0082] As Figure 2 and Figure 3 shown, in some embodiments, an installation opening 15 is provided at the position of the fixed seat 10 corresponding to the sealing device, and the sealing device can be installed in the connection cavity 21 through the installation opening 15.

[0083] Specifically, after the temperature sensor of the storage cavity 03 is clamped to the fixed seat 10, the user can press and fill the sealing putty into the connection cavity 21 through the installation opening 15 to seal the connection cavity 21.

[0084] It can be understood that if the sealing putty is pressed and filled into the connection cavity 21 before the installation of the temperature sensor of the storage cavity 03 and the fixed box 20 is completed, the user cannot continue to adjust the length of the temperature sensor of the storage cavity 03 subsequently. At this time, if the wire harness of the temperature sensor of the storage cavity 03 located in the fixed seat 10 is long, it will cause the problem that the wire harness cannot be collected, affecting the aesthetics of the fixed seat 10.

[0085] Optionally, the installation opening 15 is provided at a position corresponding to the hook 12. In this way, after the fixing base 10 and the fixing box 20 are installed, the user can snap the second detection probe of the temperature sensor in the storage cavity 03 onto the fixing base 10 through the installation opening 15, or remove the detection probe from the fixing base 10. With such a setting, the user can install or remove the second detection probe of the temperature sensor in the storage cavity 03 without disassembling the fixing base 10, improving the user experience.

[0086] As Figures 3 to 5 shown, optionally, the fixing base 10 and the fixing box 20 are respectively provided with a first screw post 13 and a second screw post 24. After the fixing box 20 and the fixing base 10 are installed, the first screw post 13 and the second screw post 24 can be firmly connected by fasteners such as screws or bolts to further prevent the fixing base 10 and the fixing box 20 from falling off the inner tank 02.

[0087] As Figure 2 and Figure 3 shown, optionally, the refrigeration device is further provided with a cover plate 16, and the cover plate 16 is detachably installed at the installation opening 15. After the temperature sensor in the storage cavity is installed, the user can snap and fix the cover plate at the installation opening 15. If the user needs to disassemble the temperature sensor in the storage cavity, the cover plate 16 can be removed from the installation opening 15, and then the temperature sensor in the storage cavity can be disassembled through the installation opening 15.

[0088] As Figure 7 shown, the embodiment of the present disclosure further provides a defrosting control method for a refrigeration device, which is applied to the above refrigeration device.

[0089] The defrosting control method for the refrigeration device includes:

[0090] S101, the inner tank temperature sensor obtains the first temperature T1 of the inner tank.

[0091] S102, when the first temperature T1 is less than or equal to the first preset temperature, the inner tank temperature sensor controls the defrosting device to start.

[0092] S103, the inner tank temperature sensor obtains the second temperature T2 of the inner tank.

[0093] S104, when the preset condition is satisfied, the inner tank temperature sensor controls the defrosting device to close.

[0094] Among them, the preset condition includes that the second temperature T2 of the inner tank is greater than or equal to the second preset temperature.

[0095] If the first temperature T1 of the inner container obtained by the inner container temperature sensor is less than or equal to the first preset temperature, it is determined that frosting occurs in the inner container. At this time, the inner container temperature sensor can control the defrosting device to start to defrost the inner container.

[0096] When the defrosting device is started, the inner container temperature sensor can obtain the second temperature T2 of the inner container again. If the second temperature T2 of the inner container is greater than or equal to the second preset temperature, it is determined that the defrosting of the inner container is completed, and the defrosting device is controlled to stop.

[0097] With such a setting, the inner container temperature sensor can judge the frosting situation of the inner container in real time according to the temperature of the inner container, and control the defrosting time of the defrosting device according to the frosting situation, so as to avoid the situation of too long or too short defrosting time, and improve the user experience.

[0098] In practical applications, the first preset temperature and the second preset temperature can be set according to the actual needs of users. For example, if the first temperature T1 of the inner container obtained by the inner container temperature sensor is less than or equal to 6°C, such as the first temperature T1 is 6°C, 5°C or 4°C, it is determined that frosting occurs in the inner container. At this time, the inner container temperature sensor can control the defrosting device to start to defrost the inner container. When the defrosting device is started, the inner container temperature sensor can obtain the second temperature T2 of the inner container again. If the second temperature T2 of the inner container is greater than or equal to 15°C, such as the second temperature T2 is 15°C, 16°C or 17°C, it is determined that the defrosting of the inner container is completed, and the defrosting device is controlled to stop.

[0099] As Figure 8 shown, an embodiment of the present disclosure provides another defrosting control method for a refrigeration device, which is applied to the above refrigeration device.

[0100] The defrosting control method for a refrigeration device includes:

[0101] S201, the temperature sensor assembly obtains the first temperature T1 of the inner container.

[0102] S202, when the first temperature T1 is less than or equal to the first preset temperature, the temperature sensor assembly controls the defrosting device to start.

[0103] S203, the temperature sensor assembly obtains the second temperature T2 of the inner container.

[0104] S204, the temperature sensor assembly obtains the third temperature T3 of the storage cavity.

[0105] S204, when the preset conditions are met, the temperature sensor assembly controls the defrosting device to close.

[0106] Among them, the preset conditions include that the second temperature T2 of the inner container is greater than or equal to the second preset temperature, and the third temperature T3 is less than or equal to the third preset temperature.

[0107] Specifically, the inner liner temperature sensor and the storage cavity temperature sensor can form a temperature sensor assembly, and the storage cavity temperature sensor is used to obtain the temperature of the storage cavity.

[0108] In practical applications, the third preset temperature can be set according to actual needs. For example, when the defrosting device is turned on, the storage cavity temperature sensor can obtain the third temperature T3 of the storage cavity. If the third temperature T3 of the storage cavity obtained by the storage cavity temperature sensor is less than or equal to -17°C, for example, the third temperature T3 is -17°C, -18°C, or -19°C, the storage cavity temperature sensor determines that the defrosting is completed and controls the defrosting device to turn off.

[0109] As Figure 9 shown, an embodiment of the present disclosure also provides a defrosting control device for a refrigeration device, including a processor 501 (processor) and a memory 502 (memory). Optionally, the device may further include a communication interface 504 (Communication Interface) and a bus 503.

[0110] In addition, when the logical instructions in the above-mentioned memory 502 are implemented in the form of a software functional unit and sold or used as an independent product, they can be stored in a computer-readable storage medium.

[0111] The memory 502, as a computer-readable storage medium, can be used to store software programs and computer-executable programs, such as the program instructions / modules corresponding to the methods in the embodiments of the present disclosure. The processor 501 executes functional applications and data processing by running the program instructions / modules stored in the memory 502, that is, implements the door body detection method for the refrigeration device in the above embodiment.
