[0042] In the embodiments of the present disclosure, an intelligent household appliance device refers to a household appliance product formed by introducing microprocessor, sensor technology, and network communication technology into household appliance devices, and has the characteristics of intelligent control, intelligent perception, and intelligent application. The operation process of intelligent household appliance devices often depends on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips.

The mobile device can, for example, include a mobile phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, etc., or any combination thereof, where the wearable device includes, for example: a smart watch, a smart bracelet, a pedometer, etc.

[0044] Combined with Figures 1-3 As shown, in some embodiments, a refrigerator includes: a compressor 300, a refrigerating compartment 400, a heat storage component 500, and a heat conduction component 600. The heat storage component 500 is arranged on one side of the compressor 300 and is used to absorb and store the heat of the compressor 300. The heat conduction component 600 has a first end 610 and a second end 620. The first end 610 is detachably connected to the heat storage component 500, and the second end 620 extends into the drain port 410 of the refrigerating compartment 400.

[0045] The refrigerator provided in the embodiments of the present disclosure is adopted. By arranging a heat storage component 500 on one side of the compressor 300 of the refrigerator, the heat generated during the operation of the compressor 300 is stored. The heat conduction component 600 is detachably connected to the heat storage component 500, and the heat of the heat storage component 500 is selectively conducted to the drainage port 410 of the refrigerating compartment 400 for defrosting. By the method of conducting the heat of the compressor 300 to defrost the drainage port 410, while reducing the risk of ice blockage at the drainage port 410, the cost of defrosting the drainage port 410 is reduced, and the user experience is improved.

[0046] Optionally, the heat storage component 500 is arranged on the upper side of the compressor 300, and there is a gap between the heat storage component 500 and the compressor 300. In this way, since the heat generated during the operation of the compressor 300 naturally rises, arranging the heat storage component 500 on the upper side of the compressor 300 can absorb the heat of the compressor 300 more efficiently and improve the heat storage effect. The compressor 300 generates vibration during operation. To avoid the vibration of the compressor 300 acting on the heat storage component 500, a gap is arranged between the heat storage component 500 and the compressor 300.

[0047] Optionally, in the vertical direction, the minimum value of the gap between the heat storage component 500 and the compressor 300 is 0.5 cm. In this way, it can not only provide a buffer space for the vibration of the compressor 300 to avoid the fine displacement caused by the vibration of the compressor 300 resulting in the collision between the compressor 300 and the heat storage component 500, but also ensure that the heat of the compressor 300 is well absorbed by the heat storage component 500.

[0048] Optionally, the first end 610 is arranged above the heat storage component 500. When the first end 610 moves towards the heat storage component 500, the first end 610 is connected to the heat storage component 500. When the first end 610 moves away from the heat storage component 500, the first end 610 is separated from the heat storage component 500.

[0049] Optionally, the heat storage component 500 includes a cylindrical ceramic structure, and a plurality of through holes 510 are arranged inside the heat storage component 500 in the vertical direction. In this way, by arranging the heat storage component 500 as a porous ceramic heat storage structure, it can better absorb and store the heat of the compressor 300, and can also better cooperate with the first end 610 of the heat conduction component 600 for heat conduction.

[0050] Optionally, the plurality of through holes 510 are evenly distributed inside the cylindrical ceramic structure. In this way, it can improve the uniformity of heat storage and also improve the uniformity of heat exchange between the first end 610 of the heat conduction component 600 and the heat storage component 500.

[0051] Optionally, the heat conduction component 600 further has a trunk 630, a first end 610 is connected to one end of the trunk 630, and a second end 620 is connected to the other end of the trunk 630. In this way, the setting of the trunk 630 can ensure the length of the heat conduction component 600, so that the first end 610 of the heat conduction component 600 can extend above the heat storage component 500, and the second end 620 can extend to the drain port 410.

[0052] Optionally, the outer side of the trunk 630 is coated with a heat insulation material. In this way, the loss of heat conducted in the trunk 630 can be reduced.

[0053] It can be understood that the trunk 630 can be a rod-shaped, plate-shaped or other special-shaped structure, which is not limited here.

[0054] Optionally, the trunk 630, the first end 610 and the second end 620 are all made of heat-conducting metal materials. For example, copper. In this way, while the trunk 630, the first end 610 and the second end 620 have good heat conduction performance, they have relatively high strength and are not easily damaged.

[0055] Optionally, the first end 610 includes: a connection disk 611 and heat exchange rods 612. The connection disk 611 is arranged horizontally and is connected to one end of the trunk 630. There are multiple heat exchange rods 612, each heat exchange rod 612 is arranged vertically, the upper end of each heat exchange rod 612 is connected to the lower side wall of the connection disk 611, and the lower end of each heat exchange rod 612 faces a through hole 510. In this way, the first end 610 composed of the connection disk 611 and multiple heat exchange rods 612 can better cooperate with the heat storage component 500 of the porous ceramic heat storage structure, improve the heat exchange efficiency between the first end 610 and the heat storage component 500, and thus efficiently conduct the heat stored by the heat storage component 500 of the compressor 300 to the drain port 410 for defrosting, and improve the defrosting efficiency at the drain port 410.

[0056] Optionally, the number of the heat exchange rods 612 matches the number of the through holes 510 in the heat storage component 500. One heat exchange rod 612 is arranged corresponding to one through hole 510, and the heat exchange rod 612 is located above the corresponding through hole 510. In this way, when the first end 610 moves towards the heat storage component 500, multiple heat exchange rods 612 can respectively extend into the corresponding through holes 510, increasing the heat exchange area between the first end 610 and the through holes 510, and enabling the heat stored in the heat storage component 500 to be more efficiently conducted to the drain port 410 through the heat conduction component 600.

[0057] Optionally, the diameter of the heat exchange rod 612 is less than or equal to the inner diameter of the through hole 510. In this way, the heat exchange rod 612 can smoothly extend into the through hole 510.

[0058] Optionally, a guiding head is provided at the lower end of the heat exchange rod 612. The guiding head is a downward conical structure, and the diameter of the upper end face of the guiding head is the same as that of the heat exchange rod 612. In this way, under the guiding action of the guiding head, even if the heat exchange rod 612 is offset, it can smoothly extend into the through hole 510.

[0059] Exemplarily, when the first end 610 moves towards the heat storage assembly 500, the plurality of heat exchange rods 612 respectively extend into the through holes 510 corresponding thereto and are connected to the inner wall of the heat storage assembly 500; when the first end 610 moves away from the heat storage assembly 500, the plurality of heat exchange rods 612 are respectively pulled out from the through holes 510 corresponding thereto, so that the first end 610 is separated from the heat storage assembly 500.

[0060] Optionally, a driving assembly 640 is arranged above the first end 610. The output end of the driving assembly 640 is connected to the first end 610, and the driving assembly 640 can drive the first end 610 to move downward or upward in the vertical direction.

[0061] It can be understood that the driving assembly 640 can be any one of a telescopic driving assembly 640, an electromagnetic driving assembly 640, and a cam driving assembly 640, which will not be elaborated here.

[0062] Optionally, the output end of the driving assembly 640 and the first end 610 are connected by a heat insulation connecting rod. In this way, the heat exchange between the driving assembly 640 and the first end 610 can be reduced, and the loss of the heat conducted in the heat conduction assembly 600 can be reduced.

[0063] Optionally, the refrigerator further includes: a box body 700. The refrigerating compartment 400 is defined by the box body 700. A compressor compartment 710 is further defined inside the box body 700. The compressor 300 is arranged in the compressor 300 compartment, and the driving assembly 640 is fixed to the upper side wall of the compressor compartment 710. In this way, the compressor compartment 710 is used to support the driving assembly 640.

[0064] Optionally, the drain port 410 is arranged vertically, and the second end 620 extends into the drain port 410 in the vertical direction. In this way, the heat conducted by the second end 620 directly acts on the ice cubes inside the drain port 410, accelerating the melting of the ice cubes and improving the ice melting efficiency of the drain port 410.

[0065] Optionally, the second end 620 includes a first rod 621 and a second rod 622. The first rod 621 is vertically inserted into the drain opening 410. The lower end of the first rod 621 is connected to the trunk portion 630. The second rod 622 is horizontally lapped on the upper end surface of the drain opening 410. The upper end of the first rod 621 is connected to the middle section area of the second rod 622. In this way, the second end 620 is set as a T-shaped rod structure. The first rod 621 is inserted into the drain opening 410, and the second rod 622 is lapped on the upper end surface of the drain opening 410, so that the ice inside the drain opening 410 and the ice accumulated above the drain opening 410 can absorb heat and melt efficiently.

[0066] Optionally, the first rod 621 is a cylindrical rod, and the axis of the first rod 621 coincides with the axis of the drain opening 410. In this way, the occupation of the internal space of the drain opening 410 by the first rod 621 can be reduced, and the influence of the first rod 621 on the flow-through area of the drain opening 410 can be reduced.

[0067] Optionally, the second rod 622 is a rectangular plate structure, and the width of the second rod 622 is one-tenth of the diameter of the drain opening 410. In this way, the shielding of the upper end surface of the drain opening 410 by the second rod 622 can be reduced.

[0068] Combined Figure 4 As shown, in one embodiment, a control method for refrigerator drainage includes:

[0069] S01, the processor obtains the temperature of the drain opening of the refrigerating compartment;

[0070] S02, the processor determines the magnitude relationship between the temperature of the drain opening and the set temperature threshold;

[0071] S03, when the temperature of the drain opening is less than the first set temperature threshold, the processor controls the first end of the heat conduction component to be connected to the heat storage component;

[0072] S04, when the temperature of the drain opening is greater than or equal to the first set temperature threshold, the processor controls the first end of the heat conduction component to be separated from the heat storage component.

[0073] Adopt the control method for refrigerator drainage provided by the embodiments of the present disclosure. By obtaining the temperature at the drainage outlet and controlling the connection relationship between the heat conduction component and the heat storage component according to the magnitude of the temperature at the drainage outlet. When the temperature at the drainage outlet is relatively low, there may be an ice blockage at the drainage outlet at this time. Control the first end of the heat conduction component to be connected to the heat storage component, and conduct the heat of the heat storage component to the drainage outlet for heating and defrosting. When the temperature at the drainage outlet is relatively high, there is no risk of ice blockage at the drainage outlet at this time. Control the first end of the heat conduction component to be separated from the heat storage component to avoid conducting heat into the refrigerating compartment and affecting the fresh-keeping effect in the refrigerating compartment. By the method of conducting the heat of the compressor for defrosting the drainage outlet, while reducing the risk of ice blockage at the drainage outlet, the cost of defrosting the drainage outlet is reduced, and the user experience is improved.

[0074] Optionally, set the temperature threshold to 0.5°C. In this way, when there is an ice blockage phenomenon inside the drainage outlet, at this time, the temperature of the drainage outlet is affected by environmental factors, and the temperature reflected to the processor end may not be below 0°C. To ensure the accuracy of the processor's judgment of ice blockage at the drainage outlet, set the set temperature threshold to 0.5°C. When the temperature of the drainage outlet is less than 0.5°C, it is determined that there is an ice blockage at the drainage outlet, and control the first end of the heat conduction component to be connected to the heat storage component for heat conduction and defrosting. When the temperature of the drainage outlet is greater than or equal to 0.5°C, at this time, the risk of ice blockage at the drainage outlet is relatively low, so control the first end of the heat conduction component to be separated from the heat storage component.

[0075] Optionally, the refrigerating compartment is the fresh food compartment. In this way, the temperature of the fresh food compartment is generally between 3°C and 10°C, making the temperature at the drainage outlet higher than 0.5°C, avoiding misjudgment by the processor. Only when the side wall freezes or the food defrosts in the fresh food compartment will the defrosting water be discharged from the drainage outlet.

[0076] Optionally, the processor obtains the temperature of the drainage outlet of the refrigerating compartment, including: the processor obtains the temperature inside the drainage outlet of the refrigerating compartment. In this way, when there is an ice blockage inside the drainage outlet, the temperature inside the drainage outlet is relatively low, and the temperature of the outer wall of the drainage outlet may not be able to well reflect the ice blockage situation inside the drainage outlet. Therefore, the processor obtains the temperature inside the drainage outlet to more accurately judge the ice blockage situation of the drainage outlet.

[0077] Optionally, a temperature sensor is arranged on the inner wall of the drainage outlet. The processor obtains the temperature inside the drainage outlet of the refrigerating compartment, including: the processor obtains the temperature inside the drainage outlet sent by the temperature sensor on the inner wall of the drainage outlet.

[0078] Optionally, the processor obtains the temperature inside the drain outlet of the refrigerating compartment, including: the processor obtains multiple temperature values at multiple positions inside the drain outlet of the refrigerating compartment; the processor determines the minimum temperature value among the multiple temperature values as the temperature inside the obtained drain outlet. In this way, when ice blockage occurs inside the drain outlet, the position of the blocked ice inside the drain outlet is variable. Therefore, the processor obtains multiple temperature values at multiple positions inside the drain outlet and determines the minimum temperature value as the temperature inside the obtained drain outlet, which can more accurately reflect the ice blockage situation inside the drain outlet and improve the accuracy of determination.

[0079] Optionally, the drain outlet is a vertically arranged tubular structure, and multiple temperature sensors are arranged on the inner wall of the drain outlet along the vertical direction. The processor obtains multiple temperature values simultaneously sent by the multiple temperature sensors. In this way, by arranging multiple temperature sensors on the inner wall of the vertically arranged tubular drain outlet, the multiple temperature sensors can detect the temperatures at multiple positions in the vertical direction inside the drain outlet, more accurately reflect the ice blockage situation inside the drain outlet, and facilitate the processor to make a more accurate judgment.

[0080] Combined with Figure 5 As shown, in another embodiment, a control method for refrigerator drainage includes:

[0081] S01, the processor obtains the temperature of the drain outlet of the refrigerating compartment;

[0082] S02, the processor determines the magnitude relationship between the temperature of the drain outlet and a set temperature threshold;

[0083] S03, when the temperature of the drain outlet is less than the first set temperature threshold, the processor controls the first end of the heat conduction component to be connected to the heat storage component;

[0084] S05, the processor determines the temperature range in which the temperature of the drain outlet is located;

[0085] S06, the processor controls the contact area between the first end of the heat conduction component and the heat storage component according to the temperature range in which the temperature of the drain outlet is located.

[0086] Using the control method for refrigerator drainage provided by the embodiments of the present disclosure, the ice blockage conditions in the drainage outlet are different, and the heat required for defrosting is also different. When the ice blockage in the drainage outlet is relatively serious, there are relatively more ice cubes in the drainage outlet, the temperature inside the drainage outlet is relatively low, and the defrosting heat required is relatively more. When the ice blockage in the drainage outlet is relatively slight, there are relatively fewer ice cubes in the drainage outlet, the temperature inside the drainage outlet is relatively high, and the defrosting heat required is relatively less. Therefore, when the processor determines that defrosting is required inside the drainage outlet and controls the first end of the heat conduction component to be connected to the heat storage component, the processor controls the contact area between the first end of the heat conduction component and the heat storage component according to the temperature range where the temperature of the drainage outlet is located, thereby controlling the heat exchange amount between the heat conduction component and the heat storage component, and thus controlling the heat conducted by the heat conduction component to the inside of the drainage outlet, so that the heat inside the drainage outlet matches its defrosting requirement, reducing the influence of the defrosting heat on the temperature inside the refrigerating compartment, and while ensuring the defrosting effect of the drainage outlet, reducing the temperature fluctuation inside the refrigerating compartment.

[0087] Optionally, controlling the contact area between the first end of the heat conduction component and the heat storage component according to the temperature range where the temperature of the drainage outlet is located includes: when the temperature of the drainage outlet is in the first temperature range, controlling the contact area between the first end of the heat conduction component and the heat storage component to be the first area; when the temperature of the drainage outlet is in the second temperature range, controlling the contact area between the first end of the heat conduction component and the heat storage component to be the second area; wherein, the first area is smaller than the second area, and the minimum value in the first temperature range is greater than the maximum value in the second temperature range. In this way, when the temperature of the drainage outlet is in the relatively large first temperature range, at this time the ice blockage condition in the drainage outlet is relatively slight, and the heat required for defrosting the drainage outlet is relatively less. Therefore, the processor controls the contact area between the first end of the heat conduction component and the heat storage component to be the relatively small first area, so that the temperature conducted by the heat conduction component to the drainage outlet matches the defrosting requirement, reducing the influence of the drainage outlet defrosting on the temperature inside the refrigerating compartment. When the temperature of the drainage outlet is in the relatively small second temperature range, at this time the ice blockage condition in the drainage outlet is relatively serious, and the heat required for defrosting the drainage outlet is relatively more. Therefore, the processor controls the contact area between the first end of the heat conduction component and the heat storage component to be the relatively large second area, so that the heat conduction component conducts relatively more heat to the drainage outlet for defrosting, improving the defrosting efficiency of the drainage outlet.

[0088] Optionally, the first temperature range is a temperature range greater than -3°C and less than 0.5°C, and the second temperature range is a temperature range less than or equal to -3°C.

[0089] Optionally, the processor controls the contact area between the first end of the heat conduction component and the heat storage component to be a first area, including: the processor controls the first end of the heat conduction component to move a first distance toward the heat storage component; the processor controls the contact area between the first end of the heat conduction component and the heat storage component to be a second area, including: the processor controls the first end of the heat conduction component to move a second distance toward the heat storage component; wherein, the second distance is greater than the first distance. In this way, since the first end of the heat conduction component is located above the heat storage component, the first end of the heat conduction component has a plurality of heat exchange rods, and the heat exchange rods move toward the heat storage component and extend into the through holes inside the heat storage component to connect and exchange heat with the inner wall of the heat storage component. Therefore, by controlling the magnitude of the distance that the first end moves toward the heat storage component by the processor, the depth of the plurality of heat exchange rods at the first end extending into the heat storage component can be controlled, thereby controlling the contact area between the first end and the heat storage component. The greater the distance that the first end moves toward the heat storage component, the greater the contact area between the first end and the heat storage component. Therefore, when the processor controls the first end to move a relatively small first distance toward the heat storage component, the contact area between the first end and the heat storage component is a relatively small first area, and when the processor controls the first end to move a relatively large second distance toward the heat storage component, the contact area between the first end and the heat storage component is a relatively large second area.

[0090] It can be understood that the distance that the processor controls the first end component to move toward the heat storage component is essentially to control the driving stroke of the driving component, and the driving stroke of the driving component can be controlled by controlling the on-off duration of the driving component or by controlling the travel switch of the driving component. In addition, there is a corresponding relationship between the driving stroke of the driving component and the temperature range in which the temperature of the drain outlet is located. When the processor determines the temperature range in which the temperature of the drain outlet is located, it immediately determines the driving stroke of the driving component, and more corresponding relationships between the driving stroke and more temperature ranges can also be set, which will not be elaborated here.

[0091] Combined with Figure 6 As shown in the figure, in one embodiment, a control method for draining water from a refrigerator includes:

[0092] S07, the processor determines that the drain outlet of the refrigerating compartment is in a draining state;

[0093] S01, the processor obtains the temperature of the drain outlet of the refrigerating compartment;

[0094] [[ID=I7]]S02, the processor determines the magnitude relationship between the temperature of the drain outlet and the set temperature threshold;

[0095] S03, when the temperature of the drain outlet is less than the first set temperature threshold, the processor controls the first end of the heat conduction component to be connected to the heat storage component;

[0096] S04. When the temperature at the drain outlet is greater than or equal to the first set temperature threshold, the processor controls the separation of the first end of the heat conduction component from the heat storage component.

[0097] By using the control method for refrigerator drainage provided in the embodiments of the present disclosure, to avoid the processor frequently obtaining the temperature of the drain outlet for judgment, before the processor obtains the temperature of the drain outlet for judgment, it is necessary to determine that the drain outlet is in the drainage state. When the drain outlet is in the drainage state, the processor obtains the temperature of the drain outlet for the next step of control, which simplifies the operation logic of the processor and reduces energy consumption.

[0098] Optionally, for the processor to determine that the drain outlet of the refrigerating compartment is in the drainage state, it includes: the processor obtains whether there is a water flow signal in the drain outlet; when there is a water flow signal in the drain outlet, the processor determines that the drain outlet is in the drainage state. In this way, by obtaining the water flow signal existing in the drain outlet to determine that the drain outlet is in the drainage state, the accuracy of determining the drainage state of the drain outlet can be improved.

[0099] Optionally, a water flow sensor is arranged inside the drain outlet. When the processor obtains whether there is a water flow signal in the drain outlet, it includes: the processor obtains whether there is a water flow signal in the drain outlet through the water flow sensor arranged in the drain outlet. In this way, by arranging a water flow sensor inside the drain outlet and obtaining whether there is a water flow signal in the drain outlet through the water flow sensor, the accuracy of obtaining the water flow signal is improved.

[0100] Optionally, when the water flow sensor sends an electrical signal, there is a water flow signal in the drain outlet.

[0101] Combined with Figure 7 As shown in

[0102] S01. The processor obtains the temperature of the drain outlet of the refrigerating compartment.

[0103] S02. The processor determines the magnitude relationship between the temperature of the drain outlet and the set temperature threshold.

[0104] S03. When the temperature of the drain outlet is less than the first set temperature threshold, the processor controls the connection of the first end of the heat conduction component to the heat storage component.

[0105] S08. The processor obtains the increase value of the temperature at the drain outlet per unit time.

[0106] S09. When the increase value of the temperature is less than the set value, the processor issues an alarm prompt to the user.

[0108] Using the control method for refrigerator drainage provided by the embodiments of the present disclosure, when the processor determines that there is ice blockage in the drainage port, it controls the first end of the heat conduction component to be connected to the heat storage component to conduct heat to the inside of the drainage port for defrosting. When there is a large accumulation of ice cubes in the drainage port and the ice blockage situation in the drainage port is serious, it may not be possible to effectively defrost by conducting the heat of the compressor. To ensure the defrosting efficiency and improve the drainage efficiency of the drainage port, after the processor controls the first end to be connected to the heat storage component, it obtains the temperature increase value at the drainage port per unit time. When the temperature increase value at the drainage port per unit time is less than the set value, the defrosting requirement of the drainage port cannot be met, and the processor issues an alarm prompt to the user, prompting the user to manually clean it to ensure the drainage efficiency of the drainage port.

[0109] Optionally, the set value is 5°C. In this way, when the temperature increase value at the drainage port per unit time is less than 5°C, at this time, it is not possible to effectively defrost the drainage port by conducting heat through the heat conduction component.

[0110] Optionally, the unit time is 10 minutes. In this way, the processor obtaining the temperature increase value at the drainage port within 10 minutes can reflect the defrosting situation at the drainage port.

[0111] Optionally, the processor obtains the first temperature value at a time point in the environment, and obtains the second temperature value of the environment again after the unit time, and determines that the difference between the first temperature value and the second temperature value is the temperature increase value per unit time.

[0112] Optionally, the refrigerator further includes a speaker, and the processor issues an alarm prompt in the form of voice broadcast to the user through the speaker. In this way, the user can more intuitively understand the alarm prompt information.
