All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Because defrosting needs, a defrosting water receiving disc for storing defrosting water is arranged in the compressor bin, a section of condenser pipeline is usually arranged in the defrosting water receiving disc to ensure that the defrosting water does not overflow, and heating and evaporation of the defrosting water are realized by utilizing partial heat dissipation of the condenser during refrigeration of the compressor. The evaporation rate of water is closely related to the water temperature, the air flow rate on the water surface, the contact area between the water surface and the air, and other factors. The energy-saving effect can be achieved by utilizing the mode that partial heat generated by the condenser pipeline heats defrosting water when the compressor runs, but in practical application, the evaporation speed is closely related to the running condition of the compressor, the opening rate of the refrigerator compressor, the use environment, the humidity of placed articles and other influencing factors need to be considered, and when the running rate of the compressor is low, the heating effect is poor. And the defrosting water quantity difference of different use environments is larger in different time periods, and in order to ensure that the defrosting water does not overflow, a mode of increasing the capacity of a defrosting water receiving disc is generally adopted. Under certain severe working conditions, the defrosting interval is shortened, and the defrosting water in the defrosting water pan is gradually increased, so that the design redundancy of the capacity of the defrosting water pan is required to be increased, and the capacity of the defrosting water pan of the air-cooled refrigerator in the market at present is generally more than 1.5-5 liters. This requires a large compressor compartment space. At present, the volume of the compressor and the condenser are miniaturized, and the space occupied by the water receiving disc becomes an important factor affecting the use volume of the refrigerator.
In order to solve the problems, the application provides a water receiving disc auxiliary heating control method for a refrigerator and the refrigerator, wherein the water receiving disc auxiliary heating control method for the refrigerator is applied to the refrigerator comprising a water receiving disc and a water receiving disc auxiliary heater, the water receiving disc auxiliary heater is tightly attached to the bottom of the water receiving disc, and the water receiving disc is subjected to auxiliary heating by controlling the opening and closing of the water receiving disc auxiliary heater. As shown in fig. 1, the method comprises the steps of:
And acquiring defrosting heating time, wherein the defrosting heating time is the defrosting time of the refrigerator in the defrosting heating process performed last time. The defrosting heating time is single defrosting time of the refrigerator, the defrosting heating time reflects the quantity of defrosting water, and the longer the defrosting heating time is, the more the quantity of defrosting water is. Because of the large difference of the defrosting water amounts in different time periods and different use environments, the defrosting time of the last time is obtained, and the accuracy of the defrosting time under different working conditions is ensured.
And if the defrosting heating time is longer than the target time, determining the heating power and the heating proportion of the auxiliary heater of the water receiving disc according to the defrosting heating time. The target time is the time corresponding to the time when the defrosting water evaporation can be completed without auxiliary heating. Judging whether to start the auxiliary water receiving tray heater according to the defrosting heating time and the target time, namely judging whether the auxiliary water receiving tray heater meets starting conditions or not, if the defrosting heating time is larger than the target time, indicating that the defrosting water quantity is larger, and if the auxiliary water receiving tray heater needs to be started for auxiliary heating, further determining the heating power and the heating proportion of the auxiliary water receiving tray heater according to the defrosting heating time. The target time may be 20 minutes, which may be set by a user according to the state of the refrigerator, which is not limited in the present application.
And generating a control instruction based on the heating power and the heating proportion, wherein the control instruction is used for starting the water-receiving tray auxiliary heater at a preset interval after the refrigerator performs the defrosting heating process last time, so that the water-receiving tray auxiliary heater carries out auxiliary heating on the water-receiving tray according to the heating power and the heating proportion.
In this embodiment, the start-stop and control of the auxiliary heater of the water-receiving tray are associated with defrosting heating time, and whether to start the auxiliary heater of the water-receiving tray is judged according to the defrosting heating time and target time. And the heating power and the heating proportion are dynamically adjusted according to the defrosting water quantity, so that the defrosting water is evaporated in the minimum defrosting period. Because the water temperature of the defrosting water in the stage of just discharging is lower, the water temperature is increased after the compressor is operated for a period of time, and the auxiliary heater of the defrosting water pan can be arranged to heat the defrosting water pan in an auxiliary mode within 1 hour after defrosting is finished so as to evaporate the defrosting water.
If the defrosting heating time is smaller than or equal to the target time, the defrosting water quantity is not large, the auxiliary heater of the water receiving disc is not required to be started for auxiliary heating, and an instruction for indicating the auxiliary heater of the water receiving disc to be closed before the refrigerator executes the next defrosting heating process is completed is generated. I.e. the instruction that the auxiliary heater of the water pan does not work before the next defrosting is completed. The defrosting water heater is controlled to be started and stopped according to the defrosting water quantity, and the defrosting water heater is controlled to perform auxiliary heating only when the defrosting water quantity is large, and the defrosting water is evaporated before the next defrosting begins. On the premise of ensuring that the defrosting water can be evaporated, the energy consumption is greatly reduced, and the cost is reduced.
According to the defrosting water heater, the auxiliary heater of the defrosting water tray is added at the bottom of the defrosting water tray, the auxiliary heater heating control is added, the starting and control of the auxiliary heater of the defrosting water tray are related to defrosting heating time, heating power and heating proportion are dynamically adjusted according to defrosting water quantity, when defrosting water quantity is large, the heating proportion and heating power are controlled, and evaporation of defrosting water is completed before next defrosting begins, so that defrosting water is evaporated in a minimum defrosting period. The capacity of the water receiving disc is reduced, the space of the compressor bin occupied by the water receiving disc is reduced, and the effective use volume of the refrigerator is increased. The energy consumption of the refrigerator is reduced while the reliability of defrosting water evaporation is ensured.
The method steps for determining the heating power and the heating proportion of the auxiliary heater of the water pan according to the defrosting heating time are further described below.
The step of determining the heating power of the defrosting auxiliary heater according to the defrosting heating time comprises the following steps:
If the defrosting heating time is in the first preset interval, the heating power is low, and the heating proportion is 25% -40%.
If the defrosting heating time is located in a second preset interval with the value higher than that of the first preset interval, the heating power is middle power, and the heating proportion is 45% -60%.
If the defrosting heating time is in a third preset interval with a value higher than that of the second preset interval, the heating power is high, and the heating proportion is 65% -80%.
The numerical ranges of the first preset interval, the second preset interval and the third preset interval may be set according to actual situations, as shown in fig. 2, for example, the target time is 20 minutes, the first preset interval is 20-30 minutes, that is, greater than 20 minutes and less than or equal to 30 minutes, the second preset interval is 30-40 minutes, that is, greater than 30 minutes and less than or equal to 40 minutes, and the third preset interval is greater than 40 minutes. And acquiring defrosting heating time, and if the defrosting heating time is less than or equal to 20 minutes, generating an instruction for indicating the auxiliary heater of the water receiving disc to be closed before the refrigerator executes the next defrosting heating process. If the defrosting heating time is more than 20 minutes, the heating power and the heating proportion of the auxiliary heater of the water receiving disc are further determined according to the defrosting heating time. If the defrosting heating time is less than 20 minutes and less than or equal to 30 minutes, the heating power is low, and the heating proportion is 25% -40%; if the defrosting heating time is less than 30 minutes and less than or equal to 40 minutes, the heating power is the intermediate power, and the heating proportion is 45% -60%; if the defrosting heating time is more than 40 minutes, the heating power is high, and the heating proportion is 65-80%. Based on the heating power and the heating ratio, a control instruction for starting the water pan auxiliary heater 1 hour after the refrigerator has last performed the defrosting heating process is generated.
The heating proportion is the ratio of the starting auxiliary heating time to the total time in the process of alternately executing the starting auxiliary heating and stopping auxiliary heating on the water receiving disc, and the total time is the sum of the starting auxiliary heating time and the stopping auxiliary heating time. The auxiliary heating stopping time is a constant value, and the auxiliary heating stopping time is 3-5 minutes. The application sets the time of stopping auxiliary heating of the auxiliary heater of the water receiving tray as a constant value, and controls the time of starting auxiliary heating of the auxiliary heater of the water receiving tray so as to meet the specified heating proportion. The auxiliary heater of the water receiving tray responds to the control instruction, and the circulation process of starting auxiliary heating and stopping auxiliary heating is alternately executed on the water receiving tray according to the target heating proportion until the refrigerator starts to defrost next time, and the circulation is stopped.
For example, as shown in fig. 3, if the heating ratio is 50%, the auxiliary heater for the water pan alternately performs the on-state and the off-state of the auxiliary heating, and fig. 3 is a schematic diagram of a heating cycle of the auxiliary heater for the water pan according to the heating ratio of 50%, wherein a solid line represents a time of starting the auxiliary heating, a dotted line represents a time of stopping the auxiliary heating, and the alternately performed cycle is started for 3min, stopped for 3min, … …, started for 3min, and stopped for 3min. If the refrigerator starts defrosting, the present heating cycle ends.
In this embodiment, the heating power and the heating proportion of the auxiliary heater for the water-receiving tray are determined according to the defrosting heating time, the defrosting heating time reflects the amount of defrosting water, the longer the defrosting heating time is, the more the defrosting water is, the higher the heat required for compensating for one time of maximizing the defrosting water is, and the higher the heating power of the auxiliary heater for the water-receiving tray is, the longer the required heating time is. Three preset sections are set, namely a first preset section, a second preset section and a third preset section, wherein the value of the second preset section is higher than that of the first preset section, and the value of the third preset section is higher than that of the second preset section. If the defrosting heating time is in the first preset interval, the heat required to be compensated for evaporating the defrosting water quantity for the time is low, and the auxiliary heater of the water receiving disc is controlled to heat according to low power, wherein the heating proportion is 25% -40%; if the defrosting heating time is in the second preset interval, the heat required to be compensated for evaporating the defrosting water quantity for the time is medium, and the auxiliary heater of the water receiving disc is controlled to heat according to the intermediate power, wherein the heating proportion is 45% -60%; if the defrosting heating time is in the third preset interval, the heat required to be compensated for evaporating the defrosting water quantity for the time is higher, and the auxiliary heater of the water receiving disc is controlled to heat according to high power, wherein the heating proportion is 65% -80%. The reliability of defrosting is ensured, and the energy consumption of the refrigerator is reduced.
In the specific implementation process of the invention, the power of the auxiliary heater of the water receiving tray is determined according to the heat quantity required to be compensated for completing the once maximum frost water quantity, and the heat utilization rate is determined. The corresponding heating proportion can be adjusted according to actual conditions, and the evaporating speed can be influenced due to the contact area of defrosting water in the water receiving disc and air, so that the heating proportion is required to be increased when the plane occupation area of the water receiving disc is reduced, and the defrosting water can be evaporated.
As shown in fig. 4, a schematic diagram of an exemplary compressor compartment structure is provided in this embodiment, a refrigerator applied by the method includes a compressor compartment 1 disposed at the bottom of a refrigerator body, and a compressor 2, a water pan 3 and a water pan auxiliary heater 4 are disposed in the compressor compartment 1.

The water receiving disc auxiliary heater 4 is tightly attached to the bottom of the water receiving disc 3 and fixed on a bottom plate of the compressor for carrying out auxiliary heating on the water receiving disc 3. Due to the fact that the defrosting water tray auxiliary heater 4 is added to carry out auxiliary heating on the defrosting water tray 3, the evaporation speed of defrosting water stored in the defrosting water tray 3 can be obviously accelerated, the risks that defrosting water is excessively long in storage time and cannot evaporate so as to overflow are avoided, and the reliability of defrosting water evaporation is guaranteed. And because the water pan auxiliary heater 4 greatly improves the heating effect, the capacity of the water pan 3 can be reduced, the space of the compressor bin 1 occupied by the water pan 3 is reduced, and the effective use volume of the refrigerator is greatly increased.
Wherein, water collector auxiliary heater 4 adopts the aluminium foil heater, and the aluminium foil heater is as heat transfer carrier with the aluminium foil, places the heater wire between two aluminium foils or the hot melt is on the individual layer aluminium foil, and the aluminium foil heater is with self-adhesion bottom, installs and dismantles the aspect, through pasting it in water collector 3 bottoms, increases the area of heating and guarantees to be heated evenly. And because the water pan auxiliary heater 4 is in the moist environment all the time in the compressor bin 1, the water pan auxiliary heater 4 adopts the aluminium foil heater, can dampproofing and waterproofing, improve the life of water pan auxiliary heater 4.

If the auxiliary heating control is carried out without using the auxiliary heater of the water receiving tray, the capacity of the water receiving tray needs to be more than 1.5 liters, and the occupied area is 180 multiplied by 230mm. The auxiliary heater of the water receiving disc adopts an aluminum foil heater, has rated power of 20W, is attached to the bottom of the water receiving disc and is fixed on the bottom plate of the compressor.
