Description
Technical Field
The invention relates to refrigeration equipment, in particular to a refrigerator.
Background
After the air-cooled refrigerator or other refrigeration equipment operates for a period of time, the evaporator of the air-cooled refrigerator or other refrigeration equipment can generate frosting, and the frosting can influence the heat dissipation of the evaporator, so that the operation efficiency of the refrigerator is influenced. Therefore, the refrigerator or other refrigeration equipment needs to perform a defrosting operation on the evaporator after a period of refrigeration, and the evaporator is generally defrosted by using an electric heating device.
However, in the conventional defrosting method used for the refrigerator or the refrigeration equipment, preset time is set according to empirical data, and defrosting is automatically started after the refrigerator or the refrigeration equipment runs for the preset time. However, this method of empirically setting the defrosting start point is not effective in defrosting because the frost formation cannot be clearly understood. For example: in some cases, when the preset refrigeration thickness is reached, the frosting thickness of the evaporator is not high, and the electric heating device starts to work for defrosting, so that the refrigeration time of the compressor is shortened, and heating energy is wasted; in other cases, when the evaporator frost layer is already thick and needs to be defrosted, the defrosting is not allowed due to the preset time program not being reached, which affects the normal operation of the evaporator.

Detailed Description
The embodiment of the invention provides a refrigerator. This refrigerator is forced air cooling refrigerator, and it includes: a box body, a door body, an evaporator 200, a compressor, a condenser and the like. The storage compartment and the evaporator chamber communicated with the storage compartment are formed in the box body, and the evaporator chamber is formed at the rear part of the storage compartment. The evaporator chamber is extended along the vertical direction of the refrigerator, and the evaporator 200 is arranged in the evaporator chamber and provides cold energy to the storage compartment. As shown in fig. 1, the case further includes: the refrigerator comprises a refrigerator shell, an inner container 102, an air duct bottom plate 104, an air duct cover plate 103 and the like. The inner container 102 is arranged in the inner layer of the shell, and a storage compartment, an evaporator chamber and an air supply duct are formed in the inner container 102. The air duct cover plate 103 and the air duct bottom plate 104 are vertically arranged inside the inner container 102 at intervals, and the air duct bottom plate 104 is spaced from the rear wall of the inner container 102 at a certain distance. The back wall and portions of the side walls of the inner container 102 and the air duct bottom 104 together form the evaporator compartment of the refrigerator. An air supply duct is formed between the duct cover plate 103 and the duct bottom plate 104. A plurality of air inlets are formed on the air duct bottom plate 104 and the air duct cover plate 103 to allow cold air after heat exchange with the evaporator 200 to enter the storage compartment. The internal structure of an air-cooled refrigerator is well known to those skilled in the art and will not be described in detail herein.
The evaporator 200 is disposed in the evaporator chamber. In the prior art, the evaporator 200 is fixedly arranged inside the evaporator chamber, and the evaporator 200 cannot move. As shown in fig. 2 to 4, unlike the prior art, the evaporator 200 of the present embodiment is suspended inside the evaporator chamber by at least one elastic means 300, so that the evaporator 200 can move up and down within a certain range. Specifically, one end of each elastic means 300 is connected to the surface of the evaporator 200, and the other end is directly or indirectly connected to the inner wall of the evaporator chamber, so that the evaporator 200 is hung inside the evaporator chamber. In this embodiment, the elastic device 300 may be a spring. In other embodiments of the present invention, the elastic device 300 may be a rubber strip or the like having elasticity. The surface of the evaporator 200 refers to the surface of the refrigerant pipe, the fixing plates on both sides of the refrigerant pipe or other accessories connected with the outer side of the refrigerant pipe.
The above refrigerator further includes: a ranging sensor 400. The distance measuring sensor 400 is disposed above the evaporator 200, and is used for detecting a distance value from the distance measuring sensor 400 to the evaporator 200. The refrigerator determines the degree of frosting on the surface of the evaporator by the distance value. It should be understood by those skilled in the art that as the refrigerator is used for a longer time, frost is more and more deposited on the surface of the evaporator 200, the evaporator 200 is heavier and falls down, and the distance value detected by the distance measuring sensor 400 is increased. In this embodiment, the refrigerator determines the current frosting degree of the evaporator 200 according to the distance value detected by the distance measuring sensor 400, and the distance measuring sensor 400 can convert the detected distance value into an electric signal and transmit the electric signal to the main control board of the refrigerator. When the evaporator 200 frosts to a certain degree, the main control board controls the refrigerator to perform corresponding actions, for example: defrost or suspend refrigeration for a period of time.
The above refrigerator further includes: a defrosting device. The defrosting device is disposed adjacent to the evaporator 200, and is used for heating and defrosting the evaporator 200. In this embodiment, the defrosting device is a heating wire disposed at the bottom of the evaporator 200, two ends of the heating wire are connected to a power supply of the refrigerator, and the evaporator 200 is defrosted by electric heating. The distance measuring sensor 400 transmits the detected distance value to a main control board of the refrigerator in an electric signal mode, and the main control board controls the start and stop of the defrosting device according to the electric signal.
The defrosting device is further configured to turn on defrosting when the ranging sensor 400 detects that the distance value is greater than a first preset distance threshold. When the distance value detected by the distance measuring sensor 400 is smaller than a second preset distance threshold value, the defrosting is finished. The first preset distance threshold and the second preset distance threshold may be set according to the size of the evaporator 200 and the length, the set number, and the form of the elastic device 300, and the two thresholds may be pre-stored in a main control board of the refrigerator before the refrigerator leaves a factory. Specifically, during the cooling process of the refrigerator, when the distance sensor 400 detects that the distance value is greater than the first preset distance threshold, the frost formation amount on the surface of the evaporator 200 exceeds the normal range. At this time, the compressor is controlled to stop, and refrigeration is suspended. And then starting a defrosting device to defrost. As the frost is gradually melted into water and drops from the surface of the evaporator 200, the weight of the evaporator 200 is gradually reduced, and when the distance sensor 400 detects that the distance value is smaller than the second preset distance threshold, the frost on the surface of the evaporator 200 is substantially removed, and at this time, the defrosting device is turned off, and the defrosting is finished. And then restart the compressor for cooling.
