All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
In a first embodiment, the present embodiment provides a refrigerator control method, a refrigerator adopted in the method includes an inner container 11 and a housing (not shown in the figure) disposed outside the inner container, an evaporation chamber 12 and a condensation chamber 13 are disposed between the inner container 11 and the housing, an evaporator 121 and an evaporation fan 122 are disposed in the evaporation chamber 12, a condenser 131 and a water pan 132 for receiving defrosting water are disposed in the condensation chamber 13, a defrosting temperature sensor HSSNR for detecting a temperature of the chamber is disposed in the evaporation chamber 12, the refrigerator further includes an ambient temperature sensor HWSNR for detecting an ambient temperature, a freezing temperature sensor FSNR is disposed in the inner container 11, defrosting water and condensed water can flow into the water pan along a flow guide mechanism, an evaporator heater strip is disposed in the evaporation chamber 12 for heating the evaporator to defrost, the water pan is disposed in the condensation chamber, when the refrigerator system is cooled, heat emitted by the condenser is used for heating and evaporating accumulated water in the water pan, thereby avoiding a situation of overflowing of the accumulated water, and reducing an influence of the accumulated water on humidity of the refrigerator.
The refrigerator control method of the embodiment mainly aims to defrost an evaporator and remove accumulated water in a water pan at the same time, and specifically comprises the following steps:
selecting a control mode, detecting a set temperature, executing a defrosting and accumulated water removing step when the set temperature is less than a first set value T1, and otherwise, executing a conventional temperature control step;
whether change the frost and remove ponding step through detecting the settlement temperature and selecting according to the settlement temperature in this step, because when the settlement temperature is lower, it is longer to need the compressor operating duration, the condenser can last for ponding heating, consequently can in time detach ponding, consequently need not to get into and change the frost and remove the ponding step, be favorable to practicing thrift the energy consumption, only higher at the settlement temperature, compressor operating duration is short, when the heat that the condenser produced is not enough to heat evaporation ponding, create the condition that can open the compressor, make the compressor can operate.
Defrosting and accumulated water removing steps, which comprise:
a1, detecting the starting and stopping state of a compressor;
and a2, if the compressor is detected to be in a stop state, controlling the evaporation fan and the evaporator heating wire to be opened until the starting condition of the compressor is met, closing the evaporator heating wire, and starting the compressor.
According to the method, the heating wire of the evaporator is started, the evaporation fan is started, heat generated by the heating wire is blown into the inner container, the inner container is enabled to reach the starting temperature of the compressor as soon as possible, the compressor is further started, accumulated water is continuously heated by the condenser, and the purpose of accelerating evaporation of the accumulated water is achieved.
The set temperature is the target temperature of the inner container set by a user, the set temperature can be input and set through a control panel on the refrigerator, the set temperature can also be set through a remote controller or a mobile terminal connected with the refrigerator through a network, when the set temperature is low, the system has a large refrigeration requirement, the running time of the compressor is long, the heat emitted by the condenser can basically meet the requirement of accumulated water heating and evaporation, the step of defrosting and removing the accumulated water is mainly carried out under the condition that the set temperature is greater than a first set value T1, wherein the first set value T1 is set as required in the refrigeration range which can be realized by the refrigerator, the temperature of the first set value T1 is not too low, and energy waste can be caused by too low temperature, for example, the set temperature can be set to be-1 ℃.
In order to save energy consumption, whether the step of defrosting and removing accumulated water needs to be executed or not needs to be determined after the environmental temperature is detected and judged, because if the environmental temperature is higher, the compressor is started without heating, the high-temperature environmental temperature can accelerate evaporation of the accumulated water, therefore, in the step of selecting the control mode, the step of detecting the environmental temperature is also included, if the environmental temperature is not more than a second set value T2, the step of defrosting and removing the accumulated water is executed, otherwise, the step of controlling the conventional temperature is executed, the accumulated water is evaporated by the high-temperature environmental temperature, the second set value T2 can be set to 20 ℃, when the environmental temperature is more than 20 ℃, the accumulated water is naturally evaporated by utilizing the environment temperature, and the energy consumption is saved.
In the step of defrosting and removing accumulated water, the running time of a compressor is prolonged, the time for heating the accumulated water by a condenser is further prolonged, evaporation of the accumulated water is further accelerated, in the step a1, if the compressor is detected to be in an open state, the step a3 is executed, whether the freezing temperature reaches the shutdown temperature Toff or not is judged, if the freezing temperature reaches the shutdown temperature Toff, the compressor is closed, then the evaporator heating wire is controlled to be opened until the starting condition of the compressor is met, and the freezing temperature is the temperature in the inner container. If the current state is that the compressor is running, that is, the condenser is already heating and evaporating accumulated water, at this time, it is required to detect whether the freezing temperature reaches the shutdown temperature Toff like a normal refrigeration mode, if the freezing temperature reaches the shutdown temperature Toff, the compressor is turned off, meanwhile, in order to increase the working time of the compressor, after the compressor is turned off, it is also required to continue to make a condition capable of turning on the compressor again, that is, the evaporator heating wire is controlled to be turned on until the starting condition of the compressor is met, then the step close to the step a2 is executed, the evaporator heating wire is turned off, and the compressor is turned on. Wherein, the shutdown temperature Toff and the opening temperature Ton are obtained by the system according to the set temperature.
In order to save energy consumption, in the step a3, the evaporation fan is closed when the compressor is closed, the evaporation fan is closed, cold air is stopped from being continuously conveyed into the inner container, and when the closing time meets a set value, the evaporation fan and the evaporator heating wire are controlled to be opened until the opening condition of the compressor is met. By setting the limit value of the closing time, because the compressor works in the previous stage, the temperature of the evaporator is very low when the compressor works, the evaporator still has residual cold after the compressor stops, the surface temperature of the evaporator is lower than the normal temperature, if the evaporator heating wire is started immediately, the temperature of the evaporator is suddenly increased, and in order to prolong the service life of a device, the phenomenon that the temperature is suddenly changed from low temperature to high temperature to cause cracks and the like is avoided.
As a preferred embodiment, in the step of defrosting and removing accumulated water, the starting conditions of the compressor are as follows: when the refrigerating temperature is not less than the opening temperature Ton, the defrosting temperature is not less than the third set value T3 or the working time of the heating wire is not less than the fourth set value T4, the opening condition of the compressor is judged to be met when any one of the conditions is met, and when the opening condition of the compressor is met, the evaporator heating wire should be closed firstly and then the compressor is started because the evaporator heating wire and the compressor cannot work simultaneously. By setting the defrosting temperature not less than the third set value T3, the temperature of the evaporator is prevented from being excessively high. By setting the limitation of the working time of the heating wire, when the sensor or the heating wire is prevented from being abnormal, the program cannot jump out of the judgment condition by setting the upper limit of the heating time, for example, the third set value T3 can be set to 12 ℃, and the fourth set value T4 can be set to 20 minutes.
In order to save energy consumption, in the step a2, the evaporation fan is turned off when the evaporator heating wire is turned off, and the continuous delivery of hot air into the inner container is stopped by turning off the evaporation fan.
When it is judged that the start condition of the compressor is satisfied, it is not preferable to directly start the evaporator in order to protect the evaporator and the like, and it is also necessary to forcibly wait for a set time.
That is, in the step a2, when the starting condition of the compressor is satisfied, after the evaporation fan and the evaporator heating wire are turned off and before the compressor and the evaporation fan are turned on, a timing step is further included, and a time interval between the two steps needs to satisfy the fifth set value T5. The duration of the fifth setting value T5 can be set according to actual needs, for example, to 3 minutes, but is not limited to 3 minutes.
By setting the limit value of the closing time, because the heating wire of the evaporator at the previous stage works, the heating wire still has residual heat after stopping, the surface temperature of the evaporator is higher than the normal temperature, if the compressor is started immediately, the temperature of the evaporator is suddenly reduced, and in order to prolong the service life of the device, the phenomenon that the temperature is suddenly changed from high temperature to low temperature to cause cracks and the like is avoided.
In the step a2, after the compressor and the evaporation fan are started, whether the freezing temperature reaches a shutdown temperature Toff or not is judged, if the freezing temperature reaches the shutdown temperature Toff, the compressor and the evaporation fan are closed, and then the step of selecting the control mode is returned, wherein the freezing temperature is the temperature in the inner container. According to the setting of the main program, the purpose of starting the compressor and the evaporation fan is to refrigerate the inner container, and the temperature adjusting target is the set temperature. And after the compressor and the evaporation fan are closed, returning to the step of selecting the control mode, judging the current set temperature again and selecting the control mode according to the current set temperature.
During evaporation fan and heater strip are opened, if detect the door and open, then evaporation fan and heater strip are closed in control, prevent that the user from blowing off steam from the door body with evaporation fan when opening the door, bring not good use for the user and experience, can practice thrift the energy consumption simultaneously.
During compressor and evaporation fan open, if detect the door and open, then the evaporation fan is closed in control, and is the same reason, prevents that the user from blowing off air conditioning from the door body when opening the door, brings not good use experience for the user, and at this moment, the compressor need not to stop because the opening of compressor stops generally to have guard time, if stop the compressor and can increase system operating time.
