The refrigeration principle of the refrigerator is as follows: the compressor compresses the refrigerant gas and discharges the compressed refrigerant gas at high pressure; the high-pressure gaseous refrigerant discharged by the compressor enters the condenser and is cooled by cooling water or air at normal temperature to be condensed into high-pressure liquid; the high-pressure liquid is throttled when flowing through the expansion valve, becomes a low-pressure low-temperature gas-liquid two-phase mixture, enters the evaporator, the liquid refrigerant in the evaporator is evaporated and refrigerated, and the generated low-pressure steam is sucked by the compressor again, so that the process is repeated and the circulation is continued.
The technical scheme of the invention provides a defrosting structure for a refrigerator, as shown in fig. 1, which comprises the following steps: the box body 10 is provided with a condensation frame 20 arranged on the upper end surface of the box body 10.

The condensing frame 20 includes an inlet end 31 and an outlet end 32, the inlet end 31 is connected to a compressor in the tank 10, and the outlet end 32 is connected to an evaporator in the tank 10. When the high-pressure gaseous refrigerant discharged from the compressor enters the condensation frame 20, the gaseous refrigerant is cooled in the condensation frame 20, condensed into high-pressure liquid, the high-pressure liquid becomes a gas-liquid two-phase mixture through the expansion valve, and enters the evaporator to complete the heat dissipation process.
The defrosting drawer 50 is arranged on the condensing frame 20, and when the condensing frame 20 dissipates heat, the heat emitted by the condensing frame 20 is transferred to the defrosting drawer 50. When food to be thawed is stored in the thawing drawer 50, the thawing drawer 50 obtains heat, and thawing of the food is completed. In the process of thawing food materials, a thawing chamber and a circuit for enabling the thawing chamber to operate are not required to be arranged independently, the thawing process can be completed according to the refrigeration principle of the refrigerator, and power consumption is saved; moreover, because the condensation frame 20 is not in a closed environment, the heat dissipation is relatively faster, and on the basis, a condensation fan used in the original refrigerator can be omitted, so that the production cost is reduced, and the refrigerator is more suitable for a small-sized air-cooled refrigerator.

It will be appreciated that the first side wall 21 may be disposed on a side of the back of the refrigerator, and the front plate of the drawer may be disposed on a side facing away from the first side wall 21, so as to facilitate use by a user. In particular, the coil-shaped condenser, after the completion of the coiling, can be wound back on the plane of the first side wall 21, i.e. in this way, when connected to the compressor and the evaporator inside the refrigerator, is connected to the back of the refrigerator, without affecting the aesthetic and normal use.

After the support frame 70 is installed on the condensation rack 20, the thawing drawer 50 is inserted into the drawer groove, the support frame 70 is attached to the bottom plate of the thawing drawer 50, and is used for supporting the thawing drawer 50, so that a user can conveniently take out or put the thawing drawer 50 into the drawer groove; on the other hand, direct abrasion to the condensing frame 20 is avoided, and the service life of the condensing frame 20 is prolonged.
In a preferred embodiment of the present invention, a temperature sensor 80 is further disposed on the support frame 70, and the temperature sensor 80 is located at the bottom of the thawing drawer 50 and connected to a controller of the refrigerator through a wire for detecting the temperature of the thawing drawer 50.
In a preferred embodiment of the present invention, the thawing drawer is a metal drawer, that is, the thawing drawer is made of metal, which is favorable for heat conduction and increases thawing speed.
The invention also provides a defrosting method for realizing the defrosting structure of the refrigerator, as shown in fig. 2, which comprises the following implementation steps:
s100, detecting the current temperature of the thawing drawer, and judging whether the current temperature is smaller than a first preset threshold value.
Specifically, the temperature of the thawing drawer may be detected by the temperature sensor, or a temperature detector may be separately placed in the thawing drawer, and various ways for detecting the current temperature of the thawing drawer are provided, which are not exemplified herein. The first preset threshold is set by the manufacturer of the refrigerator, for example, the first preset value can be set to be higher than the temperature of the food material to be thawed normally, and the specific set value can be adjusted according to actual conditions.
And S200, when the current temperature is smaller than a first preset threshold value, acquiring the ambient temperature, and judging whether the ambient temperature is smaller than a second preset threshold value.
When the current temperature is smaller than a first preset threshold, the fact that the articles (such as food materials) to be thawed are placed in the thawing drawer at the moment is indicated, and when the articles to be thawed are placed in the thawing drawer, the temperature of the thawing drawer is lowered, so that the detected current temperature is smaller than the first preset threshold. After that, the refrigerator can detect the ambient temperature, and the purpose of detecting the ambient temperature is that when the refrigerator is in a colder environment, as the condensation frame is arranged outside the refrigerator body, the temperature difference between the temperature of the condensation frame and the ambient temperature is large, the heat dissipation is fast, most of heat is emitted to the external environment, and enough heat cannot be received in the thawing drawer, so that the purpose of thawing cannot be achieved, measures are needed to increase the heat dissipation capacity of the condensation frame, and more heat is transferred to the thawing drawer to finish thawing; when the thawing drawer is in a hotter environment, based on the same principle, the thawing drawer can acquire enough heat to complete thawing, and no more heat is needed to be provided for the thawing drawer, so long as normal thawing can be completed.
In the preferred embodiment of the present invention, the second preset threshold may be a temperature in a normal temperature environment, typically 25 ℃, and the second preset threshold is set to be compared with the ambient temperature, so that season differentiation can be performed on the thawing condition, and intelligent thawing can be achieved.
And S310, controlling the refrigerator to be adjusted to the highest gear for operation when the ambient temperature is not less than a second preset threshold.
When the ambient temperature is not less than the second preset threshold, the ambient temperature is higher, and the thawing drawer can complete thawing only by acquiring a certain amount of heat. And controlling the refrigerator to operate at the highest gear, and radiating heat by the condensation frame, so that the temperature of the thawing drawer is increased, and thawing is facilitated.
The step S200 further includes:
and S320, when the ambient temperature is smaller than a second preset threshold value, controlling the current shutdown temperature of the refrigerator to be adjusted to a preset defrosting shutdown temperature for operation, wherein the defrosting shutdown temperature is smaller than the normal shutdown temperature of the refrigerator.
When the ambient temperature is less than a second preset threshold, indicating that the ambient temperature is low, the condensation frame needs to transfer more heat to the thawing drawer to complete thawing. A defrost shutdown temperature is set, which may preferably be set to a temperature 2 deg.c below the normal shutdown temperature. For example, when the normal shutdown temperature of the refrigerator is-25 ℃, and the defrost shutdown temperature is-27 ℃.
The step S320 further includes:
s321, stopping the compressor after the refrigerator reaches the defrosting stop temperature.
For example, when the refrigerator is operating normally, it is stopped when the normal stop temperature reaches-25 ℃, and at this time, the condensing frame stops radiating heat. However, since the ambient temperature is low and the defrosting effect is not good, the current shutdown temperature can be adjusted to be the defrosting shutdown temperature, namely-27 ℃. The refrigerator operates at-27 ℃ according to the defrosting stop temperature, and when the temperature of the refrigerator is low to-27 ℃, the compressor is stopped, so that the heat dissipation time of the condensing frame is prolonged, namely, more heat is provided for the defrosting drawer.
S322, when the refrigerator reaches the normal starting temperature, the compressor is controlled to start according to a preset starting and stopping period.
When the temperature in the refrigerator rises to the normal starting temperature, the compressor is started according to a preset starting and stopping period. Specifically, the preset start-stop period is three periods, and each period is started and stopped once. That is, the start-up temperature of each cycle is a normal start-up temperature, and the shutdown temperature is a defrosting shutdown temperature. It can be understood that the defrosting stop temperature and the original normal stop temperature are arranged in the refrigerator program, when the refrigerator returns to the temperature and reaches the normal start temperature, the compressor operates, the temperature in the refrigerator is reduced, and when the temperature is reduced to the defrosting stop temperature, the compressor stops; the temperature rises, the temperature in the refrigerator reaches the normal starting temperature again, and the preset starting and stopping period is completed by three cycles. The three periods are set on the basis of the strongest level of the refrigerator. By setting a preset start-stop period, the heat dissipation of the condensing frame is increased.
And S332, after the start and stop of the compressor are completed according to a preset start and stop period, the refrigerator controls the current stop temperature to be adjusted to the normal stop temperature for operation.
Specifically, because the defrosting and stopping temperature is low, in order to prevent frost formation in the refrigerator, after the refrigerator is controlled according to a preset starting and stopping period, the original refrigerating effect needs to be recovered, that is, the current stopping temperature is adjusted to the normal stopping temperature for operation.
In a preferred embodiment of the present invention, as shown in fig. 3, the determination process of the thawing method is as follows:
s1, detecting the current temperature of a thawing drawer;
s2, judging whether the current temperature is smaller than a first preset threshold value, if yes, executing a step S3; if not, returning to the step S1;
s3, obtaining the ambient temperature;

s5: controlling the refrigerator to adjust to the highest gear for running;
s6: and controlling the current shutdown temperature of the refrigerator to be adjusted to the preset defrosting shutdown temperature for operation.
