For purposes of explanation, specific details are set forth in order to provide a thorough understanding of the application. It will be apparent to one skilled in the art, however, that the application can be practiced without the specific details presented herein. In other instances, well known structures and processes are not elaborated in order to avoid obscuring the subject matter of this application. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.

[0046] Embodiments of the present application provide a refrigerator and a defrosting control method, device and storage medium thereof, which are described in detail as follows.

[0047] High-humidity-maintaining refrigerator is an important technology to achieve high-preservation effect of the refrigerator. In the refrigeration process of the refrigerator, when the moisture exchanges heat with the evaporator, the water vapor in the refrigerator will freeze on the surface of the evaporator. Therefore, the evaporator needs to be defrosted. When defrosting, the evaporator surface is heated by a defrosting module, and the frozen ice layer / frost layer is converted into water and drips into the storage box. In a high-humidity environment, more defrosting water and longer defrosting time are needed. Therefore, the defrosting water is easy to overflow the storage box. Therefore, embodiments of the present application propose a defrosting control method. Specifically, the specific steps of the defrosting control method are executed by a controller on the refrigerator.

[0048] In combination with FIGS. 1-3, Figure 1 and Figure 2 The defrosting control method comprises the following steps.

[0049] S200, acquiring a liquid level height in a storage box; the storage box is used to receive defrosting water;

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

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

[0052] The technical scheme of the embodiment of the present application acquires the liquid level height in the storage box, which is used to determine whether to immediately start defrosting, so as to avoid the situation that the storage box cannot meet the demand of defrosting water due to the remaining amount. When the liquid level height is less than the first preset height, it indicates that the current remaining amount can accommodate the defrosting water generated due to the high humidity environment, and at this time, the defrosting module is controlled to allow defrosting or start defrosting. When the liquid level height is greater than the first preset height, it indicates that the current remaining amount is difficult to accommodate the defrosting water generated due to the high humidity environment, and at this time, the heating module is controlled to heat the storage box, so that the water in the storage box evaporates and the liquid level is reduced, until the liquid level height changes from greater than the first preset height to less than the first preset height, so that the remaining amount can accommodate the defrosting water generated due to the high humidity environment, and then the defrosting module is controlled to allow defrosting.

[0053] In the embodiment, the liquid level height in the storage box is collected by a liquid level collection module. The liquid level collection module can be a liquid level sensor. The liquid level collection module can also be a ranging device, such as a radar ranging device. The radar ranging device is installed at a back plate at a preset distance above the water storage box, there is no obstruction around the lower side of the device within a certain range, 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 liquid level height is measured 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 according to 100 times of measurement of the probe. Then, before defrosting each time, the radar ranging device is turned on to collect the height X2, and then the liquid level height X3 = X1-X2.

[0055] In some embodiments, as shown in Figure 3 When the defrosting request is received, the defrosting control method of the present application is started to be executed; the defrosting request can be automatically generated when the refrigerator triggers a preset condition, at which time the liquid level collection module is controlled to start collecting the liquid level height, and then the liquid level height is acquired. The above-mentioned preset condition can be that the refrigeration temperature of the refrigerator reaches the shutdown point temperature. The defrosting request can also be triggered by the user / maintenance personnel through operation. At this time, when the liquid level height is less than the first preset height, the defrosting module starts defrosting.

[0056] As shown in Figure 3 In some embodiments, the defrosting control method comprises:

[0057] S100, acquiring a defrosting request.

[0058] S200, acquiring the liquid level height in the storage box; the storage box is used to accommodate defrosting water;

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

[0060] S410, 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 being greater than the first preset height to being less than the first preset height, controlling the defrosting module to start defrosting.

[0061] In some other embodiments, the defrosting control method of the present application is executed when no defrosting request has been received. 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 moisture 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 defrosting module is controlled to allow defrosting. That is, when the liquid level height is less than the first preset height, the defrosting module enters the working mode of defrosting after receiving the defrosting request.

[0062] As shown in Figure 4 some embodiments, the defrosting control method comprises:

[0063] S200, acquiring the liquid level height in the storage box; the storage box is used to receive defrosting water;

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

[0065] S420, 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 being greater than the first preset height to being less than the first preset height, controlling the defrosting module to allow defrosting;

[0066] After step S320 or 420, S100, acquiring a defrosting request;

[0067] When the liquid level height is less than the first preset height, the defrosting module enters the working mode of defrosting after receiving the defrosting request. That is, before the defrosting request, the liquid level height is first reduced to a state capable of receiving more defrosting water. After receiving the defrosting request, defrosting is directly started.

[0068] As an optional implementation of the above embodiments, the heating module comprises a heating module and / or a compressor of the refrigerator. In an embodiment, the heating module can be a heating sheet or a heating wire arranged on the storage box. In an embodiment, the compressor can be configured to radiate heat to the storage box, for example, the storage box is arranged close to the compressor, and the refrigerant generated by the operation of the compressor or the compressor itself can be used to radiate heat to the storage box.

[0069] Furthermore, in this embodiment, the compressor's outlet pipeline can be divided into two paths: the first path connects directly to the condenser, and the second path is positioned near or in contact with the storage box. A valve is installed on the second path, which opens when the storage box needs to be heated by the high-temperature refrigerant from the compressor. The second path can be connected to the condenser.

[0070] In an embodiment, such as Figure 5 As shown, if the liquid level 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 the second preset height, the heating module is controlled to heat the storage box; if the liquid level is greater than the first preset height and less than the second preset height, the compressor is controlled to reduce its speed.

[0072] In this embodiment, when the liquid level is greater than or less than a first preset height and less than a second preset height, the compressor is operated at a reduced speed to extend its operating time and increase the evaporation time of the water in the storage box, thereby reducing the liquid level. Conversely, when the liquid level is greater than the second preset height, the water in the storage box is directly heated by a heating module to quickly reduce the liquid level and prevent the water level from exceeding the warning line.

[0073] In other cases, after defrosting begins, due to the high humidity environment of the refrigerator, there is a significant amount of defrost water in the storage compartment. The water level may rise from below the first preset height to above it. In this situation, the compressor's operating speed can be reduced to extend its working time, increasing evaporation time and the amount of water evaporated. However, after reducing the compressor speed, the dripping rate exceeds the evaporation rate. When the liquid level exceeds the second preset height, the heating module rapidly heats the water in the storage compartment to quickly lower the liquid level and prevent it from exceeding the warning line.

[0074] As an optional implementation of the above embodiments, such as Figure 6 As shown, the defrosting 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 this embodiment, during the defrosting process, the defrosting 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 due to the fact that the dripping speed exceeds the evaporation speed, at which time the warning information is issued. In embodiments, the warning information can be a voice prompt or a text prompt. For example, the warning information can be displayed directly on the refrigerator or broadcasted by voice. For another example, the warning information can be sent to the user's APP.

[0076] In some embodiments, when the warning information is issued, the defrosting module can also be controlled to pause defrosting, and the storage box can be continuously heated to reduce the liquid level height in the storage box, and after the liquid level height is lower than the first preset height, defrosting can be started again.

[0077] As an optional implementation of the above embodiments, as shown in Figure 7 If the liquid level height is greater than the first preset height, the heating module is controlled to provide heat to the storage box, and after the liquid level height changes from being greater than the first preset height to being less than the first preset height, the defrosting module is controlled to allow defrosting or start defrosting, which further includes:

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

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

[0080] In some other embodiments, during the defrosting process, if the defrosting water dripping speed is less than the evaporation speed, the liquid level height also gradually decreases, and when the liquid level height changes to be less than the fourth preset height, the heating module is controlled to stop providing heat to the storage box, thereby reducing energy consumption.

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

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

[0083] As an optional implementation of the above embodiments, the acquiring the liquid level height in the storage box comprises:

[0084] acquiring a current operation 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, controlling the liquid level acquisition module to acquire the liquid level height according to the second acquisition mode; the acquisition times of the liquid level acquisition module in the first acquisition mode are less than the acquisition times of the liquid level acquisition module in the second acquisition mode;

[0087] acquiring the liquid level height acquired by the liquid level acquisition module according to the first acquisition mode or the liquid level height acquired by the liquid level acquisition module according to the second acquisition mode.

[0088] In the prior art, the refrigerator includes an energy-saving mode and a normal mode. For example, when the user is out, the refrigerator can be set to the energy-saving mode; and when it is normally used, the refrigerator is set to the normal mode. For another example, the refrigerator is operated in the energy-saving mode during peak electricity and is operated in the normal mode during valley electricity. The acquisition times of the liquid level acquisition module in the energy-saving mode are less than the acquisition times of the liquid level acquisition module in the 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, the controlling the liquid level acquisition module to acquire the liquid level height according to the first acquisition mode comprises:

[0091] controlling the liquid level acquisition module to acquire the current liquid level height once before defrosting starts.

[0092] In an embodiment, the acquisition module acquires the current liquid level height once before defrosting starts, so as to determine whether the first preset height is exceeded.

[0093] In another embodiment, when defrosting is not needed, the frequency of acquisition of the liquid level acquisition module or the number of starts of the liquid level acquisition module can be adjusted according to the measured liquid level height each time, so as to adapt to the energy-saving mode. For example, when the liquid level is low, the measurement times before defrosting can be reduced, so as to reduce energy consumption. When the liquid level is high, i.e., exceeds the first preset height, the system measures only once before defrosting, so as to realize real-time monitoring. The radar measurement module starts only once each time when the liquid level height is measured, so as to prevent energy waste.

[0094] As an optional implementation of the above embodiments, the control liquid level acquisition module acquires the liquid level height in the second acquisition mode includes:

[0095] Before defrosting starts, the control liquid level acquisition module acquires a plurality of current liquid level heights in a preset number of times in succession;

[0096] The liquid level height acquired by the liquid level acquisition module in the second acquisition mode includes:

[0097] The plurality of current liquid level heights are acquired;

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

[0099] That is, in the embodiments, the current liquid level height is measured in succession for a plurality of times before defrosting starts, so that the plurality of current liquid level heights are acquired, and the liquid level height is accurately measured. For example, the liquid level height is obtained by averaging the plurality of current liquid level heights, so that the liquid level height in the storage box is monitored in real time.

[0100] In the embodiments, in the normal mode, the refrigerator system automatically adjusts the working speed of the compressor according to the set gear of the refrigerating chamber and the freezing chamber and the weak gear and the liquid level height of the storage box. Different gears correspond to different speeds to adapt to different refrigeration and freezing requirements.
