It should be understood that a person of ordinary skill in the art can recognize that the invention can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0046] The embodiments of the present application provide a refrigerator and a defrost control method, device and storage medium thereof, which are described in detail below.

[0047] High moisture retention refrigerator is an important technology to achieve high freshness preservation effect of refrigerator. During the refrigeration operation of the refrigerator, when the moisture exchanges heat with the evaporator, the water vapor inside it will condense on the surface of the evaporator. Therefore, the evaporator needs to be defrosted. During defrosting, the surface of the evaporator is heated by the defrost module, and the frozen ice layer / frost layer turns into water and drips into the storage box. In a high humidity environment, more defrost water is used and the defrost time is longer. Therefore, the defrost water is very easy to overflow the storage box. To this end, an embodiment of the present application proposes a defrost control method. Specifically, the specific steps of the defrost control method are executed by a controller on the refrigerator.

[0048] Combination Figure 1 and Figure 2 As shown, the defrost control method includes:

[0049] S200, obtaining the liquid level in the storage box; the storage box is used to receive defrost water;

[0050] S300, if the liquid level is less than a first preset height, controlling the defrost module to allow defrosting or start defrosting;

[0051] S400, if the liquid level height is greater than the first preset height, control the heating module to provide heat to the storage box, and after the liquid level height changes from greater than the first preset height to less than the first preset height, control the defrost module to allow defrosting or start defrosting.

[0052] In the technical solution of the embodiment of the present application, the liquid level in the storage box is obtained to determine whether to start defrosting immediately, so as to avoid the storage box being unable to meet the demand for more defrosting water due to the remaining amount. When the liquid level is less than the first preset height, it means that the current remaining amount can bear the defrosting water generated by the high humidity environment, and the defrosting module is controlled to allow defrosting or start defrosting; and when the liquid level is greater than the first preset height, it means that the current remaining amount is difficult to bear the defrosting water generated by the high humidity environment, and the heating module is controlled to heat the storage box to evaporate the water in the storage box and lower the liquid level until the liquid level changes from greater than the first preset height to less than the first preset height, so that the remaining amount can bear the defrosting water generated by the high humidity environment, and then the defrosting module is controlled to allow defrosting.

[0053] In an embodiment, the liquid level in the storage box is collected by a liquid level acquisition module. The liquid level acquisition module may be a liquid level sensor. The liquid level acquisition module may also be a distance measuring device, such as a radar distance measuring device. The radar distance measuring device is installed on the back plate at a preset distance above the water storage box, and there is no obstruction within a certain range around the lower side of the device, and the probe is vertically downward.

[0054] Taking the radar ranging device as an example, when the refrigerator is powered on for the first time, the steps for measuring the liquid level are as follows: when powered on for the first time, the distance X1 from the probe to the bottom of the water storage box is determined by taking the average value based on 100 measurements of the probe. Then, each time before defrosting, the radar ranging device is turned on to collect the height X2, and the liquid level height X3 = X1-X2.

[0055] In some embodiments, Figure 3 As shown, after receiving the defrost request, the defrost control method of the present application is executed; the defrost request may be automatically generated by the refrigerator when the preset condition is triggered, and at this time, the liquid level acquisition module is controlled to start collecting the liquid level height, and then the liquid level height is obtained. The above preset condition may be: the refrigeration temperature of the refrigerator reaches the shutdown point temperature. The defrost request can also be triggered by the user / maintenance personnel through manipulation. At this time, when the liquid level height is less than the first preset height, the defrost module starts defrosting.

[0056] like Figure 3 As shown, in some embodiments, the defrost control method includes:

[0057] S100: Obtain a defrost request.

[0058] S200, obtaining the liquid level in the storage box; the storage box is used to receive defrost water;

[0059] S310, if the liquid level is less than a first preset height, controlling the defrost module to start defrosting;

[0060] S410, if the liquid level height is greater than the first preset height, control the heating module to provide heat to the storage box, and after the liquid level height changes from greater than the first preset height to less than the first preset height, control the defrost module to start defrosting.

[0061] In some other embodiments, when a defrost request has not been received, the defrost control method of the present application is executed. The liquid level acquisition module acquires the liquid level height; when the liquid level height is greater than the first preset height, the heating module is controlled to provide heat to the storage box so that the water in the storage box evaporates and the liquid level height is reduced; and when the liquid level height is less than the first preset height, the defrost module is controlled to allow defrosting. That is, when the liquid level height is less than the first preset height, the defrost module enters the defrost working mode after receiving the defrost request.

[0062] like Figure 4 As shown, in some embodiments, the defrost control method includes:

[0063] S200, obtaining the liquid level in the storage box; the storage box is used to receive defrost water;

[0064] S320, if the liquid level is less than a first preset height, controlling the defrost module to allow defrosting;

[0065] S420, if the liquid level is greater than the first preset height, controlling the heating module to provide heat to the storage box, and controlling the defrosting module to allow defrosting after the liquid level changes from greater than the first preset height to less than the first preset height;

[0066] After step S320 or 420, S100, obtaining a defrost request;

[0067] When the liquid level is less than the first preset height, the defrost module enters the defrost working mode after receiving the defrost request. That is, before the defrost request, the liquid level is first lowered to a state where more defrost water can be received. After receiving the defrost request, defrost starts directly.

[0068] As an optional implementation of the above embodiments, the heating module includes a heating module and / or a compressor of the refrigerator. In an embodiment, the heating module can be a heating plate or a heating wire arranged on the storage box. In an embodiment, the compressor can be configured to radiate heat to the storage box, such as the storage box is arranged close to the compressor, and the refrigerant generated during its operation or; in an embodiment, the compressor can also be configured so that its outlet pipe is close to or in contact with the storage box, so that a high-temperature refrigerant flows inside, which can be used for radiant heating or heat conduction of the storage box.

[0069] Further, in an embodiment, the outlet pipeline of the compressor can be divided into two routes, the first route is directly connected to the condenser, and the second route is arranged close to or in contact with the storage box. A valve is arranged on the second route, which is opened when the storage box needs to be heated by the high-temperature refrigerant of the compressor. The second route can be connected to the condenser.

[0070] In an embodiment, Figure 5 As shown, if the liquid level height is greater than the first preset height, controlling the heating module to provide heat to the storage box includes:

[0071] S430, if the liquid level is greater than a second preset height, control the heating module to heat the storage box; if the liquid level is greater than the first preset height and less than the second preset height, control the compressor to run at a reduced speed.

[0072] In an embodiment, when the liquid level is greater than or less than the first preset height and less than the second preset height, the compressor is slowed down to extend the working time of the compressor and increase the evaporation time of the water in the storage box to achieve the purpose of lowering the liquid level. When the liquid level is greater than the second preset height, the water in the storage box is directly heated by the heating module to quickly lower the liquid level and prevent the water in the storage box from exceeding the warning line.

[0073] In other cases, after defrosting begins, because the refrigerator is running in a high humidity environment, there is more defrosting water in the storage box, and the water in the storage box begins to increase. The water level may change from below the first preset height to above the first preset height. At this time, the operating speed of the compressor can also be reduced to extend the working time of the compressor, increase the evaporation time, and increase the evaporation amount. After reducing the operating speed of the compressor, the dripping speed exceeds the evaporation speed. When the liquid level is greater than the second preset height, the water in the storage box is quickly heated by the heating module to quickly reduce the liquid level and prevent the water in the storage box from exceeding the warning line.

[0074] As an optional implementation of the above embodiments, Figure 6 As shown, the defrost control method further includes: S500, if the liquid level is greater than a third preset height, a warning message is issued; the third preset height is greater than the first preset height. In an embodiment, during the defrosting process, the defrost water increases, and when the liquid level is greater than the third preset height, a warning message is issued, prompting the user to manually handle the water in the storage box.

[0075] For example, in some embodiments, during the defrosting process, when the water in the storage box is evaporated by the heating module, the volume of the defrosting water stored therein increases and exceeds the third preset height because the dripping speed exceeds the evaporation speed, and a warning message is issued at this time. In an embodiment, the warning message can be a voice prompt or a text prompt. For example, the warning message can be directly displayed on the refrigerator or voice broadcast. For another example, the warning message can be sent to the user APP.

[0076] In some embodiments, while issuing a warning message, the defrost module can also be controlled to suspend defrosting and continue to heat the storage box to lower the liquid level in the storage box. Defrosting can be started again after the liquid level is lower than a first preset height.

[0077] As an optional implementation of the above embodiments, Figure 7 As shown, if the liquid level height is greater than the first preset height, controlling the heating module to provide heat to the storage box, and after the liquid level height changes from greater than the first preset height to less than the first preset height, controlling the defrost module to allow defrosting or start defrosting also includes:

[0078] S440, after the liquid level height changes from greater than the first preset height to less than the first preset height, control the heating module to continue to provide heat to the storage box until the liquid level height changes to less than a fourth preset height, and then control the heating module to stop providing heat to the storage box.

[0079] In an embodiment, before defrosting begins, the liquid level height in the storage box decreases due to gradual evaporation of water after the heating module provides heat. When the liquid level height decreases to be less than a fourth preset height, the heating module is controlled to stop providing heat to the storage box, so that the storage box has surplus capacity and reduces energy consumption.

[0080] In other embodiments, during the defrosting process, if the defrosting water dripping speed is lower than the evaporation speed, the liquid level height gradually decreases. When it decreases to a level lower than a fourth preset height, the heating module is controlled to stop providing heat to the storage box to reduce energy consumption.

[0081] For example, in an embodiment, the outlet pipeline of the compressor can be divided into two routes, the first route is directly connected to the condenser, and the second route is arranged close to or in contact with the storage box. A valve is arranged on the second route, and when the liquid level drops to less than a fourth preset height, the valve is closed, and the high-temperature refrigerant passing through the compressor does not enter the second route, and the heating of the storage box is stopped at this time.

[0082] For example, in an embodiment, a heating plate or a heating wire is provided on the storage box. At this time, after the liquid level height is reduced to less than the fourth preset height, the heating plate or the heating wire stops heating.

[0083] As an optional implementation of the above embodiments, obtaining the liquid level in the storage box includes:

[0084] Obtaining the current operating mode of the refrigerator;

[0085] If the current operation mode is the energy-saving mode, controlling the liquid level acquisition module to acquire the liquid level height according to the first acquisition mode;

[0086] If the current operation mode is the normal mode, the liquid level acquisition module is controlled to acquire the liquid level height according to the second acquisition mode; the number of acquisitions performed by the liquid level acquisition module in the first acquisition mode is less than the number of acquisitions performed by the liquid level acquisition module in the second acquisition mode;

[0087] The liquid level height collected by the liquid level collection module according to the first collection mode or the liquid level height collected by the liquid level collection module according to the second collection mode is obtained.

[0088] In the prior art, refrigerators include energy-saving mode and normal mode. For example, when the user is out, the refrigerator can be set to energy-saving mode; and when in normal use, the refrigerator can be set to normal mode. For another example, the refrigerator operates in energy-saving mode during peak power periods and in normal mode during valley power periods. The number of collection times of the liquid level collection module in energy-saving mode is less than that in normal mode, so as to reduce energy consumption.

[0089] In some embodiments, the liquid level acquisition module is a radar ranging module.

[0090] As an optional implementation of the above embodiments, controlling the liquid level acquisition module to acquire the liquid level height according to the first acquisition mode includes:

[0091] Before defrosting begins, the liquid level acquisition module is controlled to acquire the current liquid level height once.

[0092] In an embodiment, before defrosting begins, the acquisition module acquires the current liquid level height once to determine whether it exceeds a first preset height.

[0093] In another embodiment, when defrosting is not required, the frequency of the liquid level acquisition module or the number of times the liquid level acquisition module is turned on can be adjusted according to the liquid level height measured each time to adapt to the energy-saving mode. For example, when the liquid level is low, the number of measurements before defrosting can be reduced to reduce energy consumption. When the liquid level is high, that is, exceeds the first preset height, the system is measured once before defrosting for real-time monitoring. Each time the liquid level is measured, the radar measurement module is only turned on once to prevent energy waste.

[0094] As an optional implementation of the above embodiments, controlling the liquid level acquisition module to acquire the liquid level height according to the second acquisition mode includes:

[0095] Before defrosting begins, the liquid level collection module is controlled to continuously collect multiple current liquid level heights according to a preset number of times;

[0096] The step of obtaining the liquid level height collected by the liquid level collection module according to the second collection mode comprises:

[0097] Obtaining the multiple current liquid level heights;

[0098] The liquid level height is determined according to the multiple current liquid level heights.

[0099] That is, in the embodiment, before defrosting begins, the current liquid level is measured multiple times continuously to obtain multiple current liquid level heights, so as to accurately measure the liquid level height. For example, the liquid level height can be obtained by averaging the multiple current liquid level heights to monitor the liquid level in the storage box in real time.

[0100] In the embodiment, when the refrigerator is in normal mode, the refrigerator system automatically adjusts the compressor operating speed according to the gear and weak gear set in the refrigerator / freezer and the liquid level of the storage box. Different gears are set to correspond to different speeds to meet different refrigeration and freezing requirements.
