Technical Field
The invention belongs to the technical field of refrigerator control, and particularly relates to a refrigerator and a defrosting control method thereof.
Background
At present, a defrosting system of a traditional refrigerator is only provided with a defrosting sensor, and the exiting of a defrosting program is controlled by judging whether the sensor meets a set temperature. Because a refrigerator usually has a defrosting heater corresponding to a defrosting sensor, the heater is controlled to be disconnected by the sensor reaching a certain temperature threshold value, generally, the defrosting sensor is arranged at the coldest position of an evaporator, usually on an inlet pipe, an outlet pipe or a left bracket and a right bracket of the evaporator, but the temperature at the position is influenced by factors such as evaporator installation, foaming deformation, air duct assembly and the like, and when the temperature rises too fast, incomplete defrosting is caused, and the refrigeration efficiency is influenced; when the temperature rises too slowly, the defrosting time is too long, the power consumption is increased, and the food storage period is affected. Once the refrigerator enters a failure mode under the condition that the defrosting sensor fails, the compressor is fixedly started and stopped according to the environment temperature sensor in the mode, and the temperature cannot be adjusted.
Disclosure of Invention
The invention aims to provide a refrigerator and a defrosting control method thereof, wherein a defrosting sensor is respectively arranged on an inlet pipeline and an outlet pipeline of a refrigerator evaporator, the signal feedback of the two sensors is comprehensively evaluated, and a defrosting exit condition is determined, so that the problems that the existing refrigerator defrosting sensor is incomplete in defrosting, poor in refrigerating efficiency and incapable of adjusting temperature once a fault occurs are solved.
In order to solve the technical problems, the invention is realized by the following technical scheme:
the invention relates to a refrigerator, which comprises a refrigerator body;
an evaporator and a heater are arranged in the refrigerator body; a defrosting sensor is respectively arranged on the inlet pipeline and the outlet pipeline of the evaporator; the defrosting sensor and the heater are both in communication connection with the main controller.
A refrigerator defrosting control method comprises the following steps:
step S1: collecting defrosting sensors on an inlet pipeline and an outlet pipeline of an evaporator of a refrigerator;
step S2: when any defrosting sensor reaches 4 ℃ and the other defrosting sensor is above 1 ℃, the defrosting is complete by default, and the refrigerator quits defrosting; otherwise, the refrigerator heater continues to work;
step S3: when any defrosting sensor reaches 10 ℃ and the other defrosting sensor is above 1 ℃, the defrosting is complete by default, and the refrigerator quits defrosting; otherwise, the refrigerator heater continues to work until the other defrosting sensor reaches 1 ℃ and then the defrosting is stopped;
step S4: when any defrosting sensor fails, the data of the other defrosting sensor is taken as the standard, and the condition that the refrigerator is stopped defrosting at 8 ℃ is met
As a preferable technical scheme, the defrosting period of the refrigerator is not more than 60min at most; and if the time exceeds 60min, the refrigerator automatically quits defrosting.
The invention has the following beneficial effects:
according to the invention, the defrosting sensors are respectively arranged on the inlet and outlet pipelines of the refrigerator evaporator, the signal feedback of the two sensors is comprehensively evaluated, and the defrosting exit condition is determined, so that the defrosting is more sufficient, the defrosting time is more reasonable, and the risk of entering a failure mode is reduced by using one sensor and one spare sensor.
Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
