Description
Technical Field
The invention relates to the field of refrigerators, in particular to a refrigerator defrosting method and a refrigerator adopting the refrigerator defrosting method.
Background
When the refrigerator is used in a frequent power failure area, if the refrigerator has power failure in a defrosting mode, how to detect the defrosting effect of the refrigerator when the refrigerator is powered on again has great influence on the use of the refrigerator. The direct-cooling refrigerator generally carries out natural defrosting, the temperature of an evaporator rises back to defrost when a compressor stops, the defrosting effect cannot be guaranteed, the defrosting effect of the direct-cooling refrigerator is guaranteed particularly in areas with frequent power failure, and no product is available at present.
In addition, for the electric control type direct-cooling refrigerator, certain conditions can be set to force the compressor to start and stop, and the refrigerating chamber is controlled to defrost.
Chinese patent document No. CN101915491A discloses a control method for defrosting of a direct-cooling refrigerator in 2010, 8 months and 3 days, which comprises the following steps: after the refrigerator is plugged, firstly sensing the temperature of an evaporator temperature sensor; if the temperature is higher than T ℃, judging that the refrigerator is powered on for the first time, timing, and defrosting after the refrigerator is powered on for T1 hours; if the temperature is lower than T ℃, judging that the refrigerator is powered on again, timing, and defrosting after the refrigerator is powered on for T2 hours; immediately after defrosting is finished, timing is started, and the timing of defrosting is selected with t3 hours as a period. The control method takes 24 hours as a period and takes 4 hours without opening and closing a door as a control point for judging whether a user normally uses the control point to carry out self-adaptive defrosting. According to the control method, after the refrigerator is powered on, the temperature of the evaporator temperature sensor is sensed, the refrigerator is judged to be powered on for the first time or powered on again, and then different entering conditions are given to primary defrosting. However, the control method is obviously unreasonable, if the refrigerator is in the defrosting mode before power failure and is powered on again when defrosting is not completed, the refrigerator is powered on for t2 hours according to the control method to defrost, and therefore the refrigerating effect and the next defrosting effect are affected.
Chinese patent document No. CN106839642A discloses a direct-cooling refrigerator and a defrosting control method and device thereof in 2017, 6 and 13, wherein the method comprises the following steps: detecting the ambient temperature of the environment where the direct cooling refrigerator is located, and detecting the temperature in a refrigerating chamber of the direct cooling refrigerator; calculating a temperature difference value between the ambient temperature and the temperature in the refrigerating chamber, and judging whether the temperature difference value is smaller than a preset value or not; if the temperature difference is smaller than the preset value, acquiring the maximum continuous operation time of the compressor in the direct-cooling refrigerator according to the temperature difference; and when the continuous operation time of the compressor reaches the acquired maximum continuous operation time, controlling the compressor to be forcibly stopped so that the direct cooling refrigerator performs defrosting action. The control method is not scientific but only establishes a set of corresponding relations between frosting and ambient temperature. The frosting on the surface of the evaporator is more influenced by the use of the refrigerating chamber, the door opening times are more, the heat exchange is more, and the frosting on the surface of the evaporator is more; on the contrary, the surface of the refrigeration evaporator is rarely frosted when the door is not opened for a long time. The invention only considers the influence of the ambient temperature on frosting and does not consider the influence of the actual use of a user on frosting.
The refrigerator has different use conditions, such as environment temperature, use frequency, food put into how much, and the like, and under different use conditions, the degree of frosting of refrigerator is very big, if do not consider user's actual use influence, only with a certain condition control refrigerator and get into the mode of defrosting, undoubtedly can increase refrigerator power consumption, cause the waste of energy. Similarly, setting a fixed time as the condition for ending defrosting regardless of the amount of frosting will certainly cause waste of energy.

Detailed Description
As shown in fig. 1, in an embodiment of the present invention, a refrigerator defrosting method is provided, which includes steps S1-S7. The details will be described below.
Step S1: and when the refrigerator is powered on again after power failure, judging the working mode of the refrigerating chamber before power failure.
It should be noted that, since the air-cooled refrigerator is generally not frozen in the refrigerating chamber, the refrigeration method of the refrigerator of the present invention is mainly used in the direct-cooling refrigerator. For a direct-cooling refrigerator, the refrigeration compartment of the refrigerator generally includes two refrigeration compartment modes of operation: a cold storage mode and a defrost mode. In the cold storage mode, the cold storage compartment refrigeration system operates to maintain the cold storage compartment temperature at a set temperature. In the defrosting mode, the refrigerating chamber refrigerating system is closed, the compensation heater is started to heat, and ice in the refrigerating chamber is melted. In the embodiment of the invention, the compensation heater is arranged around the water collecting tank of the refrigerating chamber to prevent the water collecting tank and the water outlet from icing.
Step S2: and if the cold storage mode is operated before the power failure, the cold storage mode is operated.
It should be noted that, in the embodiment of the present invention, the refrigeration mode includes two operation states, i.e., an energy saving state and a non-energy saving state, and in the non-energy saving state, the refrigeration operation power of the refrigerator is greater than the refrigeration operation power in the energy saving state. After the refrigeration mode is started, the refrigerator firstly operates in a non-energy-saving state and records the operation time of the non-energy-saving state, so that the refrigerating chamber of the refrigerator quickly reaches the set temperature, and the refrigerator automatically switches to operate in the energy-saving state after the operation time of the non-energy-saving state reaches the set time, thereby reducing the energy consumption. In the embodiment of the invention, the running time of the non-energy-saving state reaches 24 hours, and the non-energy-saving state is automatically switched to the energy-saving state to run.
As shown in fig. 2, in the energy saving state, factors that may cause a temperature change of the refrigerating compartment, such as the external ambient temperature, the single door opening time, the door opening times, and the accumulated door opening time, are further detected, and if any one of the external ambient temperature, the single door opening time, the door opening times, and the accumulated door opening time reaches the set energy saving exit condition, the energy saving state is exited, and the non-energy saving state is entered. Specifically, the set energy saving exit condition includes at least one of the following conditions:
the external environment temperature is more than or equal to 34 ℃;
the single door opening time is more than or equal to 70S;
the door opening times are more than or equal to 3;
the accumulated door opening time is more than or equal to 90S.
Step S3: if the defrosting mode is operated before the power failure, checking whether the surface temperature tr of the refrigeration evaporator reaches a defrosting exit temperature T1, and if the surface temperature tr of the refrigeration evaporator does not reach the defrosting exit temperature T1, entering a step S5 to operate the defrosting mode; if the defrosting exit temperature T1 is reached, the defrosting mode exits, and the refrigeration mode is operated by jumping to step S2.
The refrigerating chamber of the direct cooling refrigerator performs heat exchange between a refrigerating evaporator disposed in the refrigerating chamber and air in the refrigerating chamber. When the refrigerator runs, the surface temperature of the refrigeration evaporator is lower than zero, so that water vapor in the refrigerator is frozen on the surface of the evaporator, and the heat exchange effect of the refrigeration evaporator is influenced. In order to melt the ice, the surface temperature of the refrigerating evaporator needs to be raised above zero, and therefore, the frost exit temperature T1 is greater than zero and cannot be set too high, which may affect the stored food and cause waste of electric energy. The defrosting exit temperature T1 is generally set before the refrigerator leaves the factory. For example, it may be set to 1 degree.
Step S4: and in the cold storage mode, judging whether the defrosting condition is met, if so, entering step S5, entering the defrosting mode, and if not, continuing to operate the cold storage mode.
In the embodiment of the invention, in the non-energy-saving state, the condition of the defrosting mode of the refrigerator operation is at least one of the following conditions:
the accumulated refrigerating time of the refrigerating chamber reaches m1, and the refrigerating chamber reaches a stop point;
the accumulated refrigerating time of the refrigerating chamber reaches m 2;
the continuous refrigerating time of the refrigerating chamber reaches m3, and the refrigerating chamber reaches a stop point;
the continuous refrigerating time of the refrigerating chamber reaches m 4;
wherein m1, m2, m3 and m4 are set running times.
In the energy saving state, the condition of the refrigerator operating the defrosting mode is at least one of the following conditions:
the accumulated refrigerating time of the refrigerating chamber reaches m5, and the refrigerating chamber reaches a stop point;
the accumulated refrigerating time of the refrigerating chamber reaches m 6;
the continuous refrigerating time of the refrigerating chamber reaches m7, and the refrigerating chamber reaches a stop point;
the continuous refrigerating time of the refrigerating chamber reaches m 8;
wherein m5, m6, m7 and m8 are set running times.
It should be noted that, when the refrigerator works in an energy-saving state, the frosting is less, and a longer running time can be set to enter a defrosting mode; the refrigerator works in a non-energy-saving state, frosting is more, and short running time can be set to enter a defrosting mode. The defrosting control method is economical and energy-saving, and is beneficial to food storage.
Step S5: and entering a defrosting mode, recording the running time of the defrosting mode and detecting the surface temperature of the refrigeration evaporator.
Step S6: and judging whether the condition for exiting the defrosting mode is met, if so, entering the step S7 to exit the defrosting mode, otherwise, entering the step S5 to continue operating the defrosting mode.
It should be noted that, in the embodiment of the invention, the defrosting mode exit condition is that the operating time HS of the defrosting mode reaches the set defrosting operating time HS, and the surface temperature tr of the refrigerating evaporator reaches the set defrosting exit temperature T1.
In the defrosting mode, the refrigerating chamber is heated by the compensating heater, and the heating power is usually fixed at the time of factory shipment, so the defrosting effect can be controlled by setting the defrosting operation time HS at the time of factory shipment, and the user can also set the defrosting operation time HS in the control interface of the refrigerator to cope with icing conditions of different degrees. In addition, if the surface temperature tr of the refrigerating evaporator reaches the set defrosting exit temperature T1, it indicates that the surface ice formation of the refrigerating evaporator has been dissolved. Therefore, in the defrosting mode, the operation time of the defrosting mode is detected, and if the operation time of the defrosting mode reaches the set defrosting operation time, the defrosting mode is exited. And in the defrosting mode, detecting the surface temperature of the refrigerating evaporator, and if the surface temperature of the refrigerating evaporator reaches a defrosting exit temperature, exiting the defrosting mode.
Step S7: the defrosting mode is exited, and the process returns to step S2 to enter the cold storage mode.
In summary, in the defrosting method for the refrigerator of the present invention, when the refrigerator is powered on again after power failure, the refrigerator operates according to the working mode of the refrigerating chamber before power failure, if the defrosting mode is operated before power failure, it is checked whether the surface temperature of the refrigerating evaporator reaches the defrosting exit temperature, and if the defrosting exit temperature is not reached, the defrosting mode continues to be operated; if the defrosting exit temperature is reached, the defrosting mode is exited, so that the influence of the defrosting effect of the refrigerator during frequent power failure is prevented; different defrosting mode entering conditions are set according to the energy-saving state and the non-energy-saving state of the refrigerator, so that the refrigerator is economical and energy-saving and is beneficial to food storage; the accumulated defrosting time or the surface temperature of the refrigeration evaporator is used as a condition for exiting the defrosting mode, so that the energy consumption can be reduced, and the influence of defrosting on the temperature of the compartment can be reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
