[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] Reference Figures 1-11 As shown, this embodiment of the present invention provides a refrigerator, comprising: The compressor 100, condenser 200, fan 300, and water tray assembly 400 are provided; the condenser 200 is located on one side of the compressor 100; the fan 300 is located between the compressor 100 and the condenser 200; and the water tray assembly 400 is located on one side of the compressor 100.

[0019] The drip tray assembly 400 includes a drip tray body 410 and an air guide component 420. The drip tray body 410 has a chamber 411 for holding defrost water; the air guide component 420 is located on one side of the drip tray body 410; the air guide component 420 includes an air guide body 421 and an air duct 422 disposed in the air guide body 421; the two ends of the air duct 422 are an air inlet 4221 and an air outlet 4222, respectively; the cross-sectional area of ​​the air inlet 4221 is larger than the cross-sectional area of ​​the air outlet 4222; the air outlet 4222 is disposed facing the bottom of the chamber 411; the air inlet 4221 of the air guide component 420 of the drip tray assembly 400 is disposed facing the fan 300.

[0020] Specifically, during refrigerator operation, under the action of fan 300, a portion of the airflow from condenser 200 enters the air inlet 4221, passes through air duct 422, and exits from air outlet 4222. The air exiting from air outlet 4222 blows towards the bottom of cavity 411, thus directly blowing the defrost water in cavity 411. That is, this application changes the horizontal airflow direction and guides it into the drip tray body 410. At the same time, the cross-sectional area of ​​air inlet 4221 is larger than that of air outlet 4222, effectively increasing the air velocity at air outlet 4222, ultimately evaporating the defrost water in drip tray body 410 quickly. Therefore, this application effectively changes the airflow direction while increasing the air velocity, effectively improving the evaporation efficiency of defrost water and preventing defrost water overflow that could cause refrigerator leakage.

[0021] This embodiment can evaporate defrost water relatively quickly even under certain low wind speed operating conditions.

[0022] The rapid evaporation of defrost water in the drip tray 410 can quickly remove the heat from the compressor 100 compartment (to cool down the compressor 100) and also prevent problems such as water leakage at the bottom of the refrigerator.

[0023] This application ensures that high evaporation efficiency can be maintained even at low water levels.

[0024] Furthermore, along the direction of airflow V, the air guide body 421 includes an air inlet section 4223 and an air outlet section 4224; the air inlet section 4223 and the air outlet section 4224 are smoothly transitioned; along the direction of airflow V, the air inlet section 4223 is inclined upward from bottom to top, and the air outlet section 4224 is inclined downward from top to bottom.

[0025] Specifically, in this embodiment, the air inlet section 4223 allows as much airflow as possible to enter the air duct 422, and the inclined air outlet section 4224 causes the air outlet 4222 to face the bottom of the chamber 411, thereby facilitating the airflow to be guided onto the defrost water in the chamber 411 for rapid evaporation.

[0026] Furthermore, the air intake section 4223 is set horizontally.

[0027] Specifically, since the wind direction is horizontal before entering the water tray assembly 400, the air inlet section 4223 of this application is designed to be horizontal in the same direction as the wind, so as to reduce wind resistance and increase the speed of airflow when the airflow enters the air duct 422.

[0028] Furthermore, the air outlet 4222 is higher than the upper surface of the water receiving tray body 410.

[0029] Specifically, this embodiment ensures the volume of the water receiving tray body 410. This prevents the air outlet 4222 from extending into the chamber 411 and being submerged by defrost water, which could lead to failure.

[0030] Furthermore, a notch 412 is provided on one side of the water receiving tray body 410; a connecting part 4211 is provided in the air guide body 421 near the air inlet 4221; one of the sidewalls of the notch 412 and the connecting part 4211 is provided with a first retaining platform 413 and the other with a first retaining groove 4212; the first retaining groove 4212 cooperates with the first retaining platform 413. In some embodiments, the sidewall of the notch 412 is provided with the first retaining platform 413, and the sidewall of the connecting part 4211 is provided with the first retaining groove 4212. In this way, only the notch 412 needs to be opened on the original water receiving tray body 410 to form the first retaining platform 413 on the sidewall of the water receiving tray body 410, and then the first retaining groove 4212 can be directly opened when producing the connecting part 4211. It can be seen that the modification to the original water receiving tray body 410 is minimal, reducing costs.

[0031] Furthermore, along the direction of the airflow V, the air intake section 4223 tilts forward from bottom to top.

[0032] Specifically, the air guide component 420 is directly installed on the top of the water receiving tray assembly 400, so that a notch 412 is directly opened on the original water receiving tray body 410, and the air inlet 4221 is installed at the notch 412. In order to ensure that the air outlet 4222 is higher than the upper surface of the water receiving tray body 410, the air inlet section 4223 is tilted forward from bottom to top.

[0033] Furthermore, along the direction of airflow V, the cross-sectional area of ​​air duct 422 gradually decreases.

[0034] Specifically, in this embodiment, the cross-sectional area of ​​the air duct 422 gradually decreases, thereby reducing wind resistance, further increasing the effective wind speed of the air outlet 4222, and improving the evaporation efficiency of the defrost water.

[0035] Furthermore, along the direction V of the airflow, the width of the air duct 422 remains unchanged, while the height of the air duct 422 gradually decreases.

[0036] Specifically, in this embodiment, the height of the air duct 422 is changed so that the cross-sectional area of ​​the air duct 422 is changed while the width of the air duct 422 remains unchanged, thereby reducing the processing difficulty and reducing the cost.

[0037] Furthermore, the air guide body 421 includes an upper air guide 4213 and a lower air guide 4214; the upper air guide 4213 and the lower air guide 4214 are connected vertically.

[0038] Specifically, in this embodiment, the air guide body 421 is divided into an upper air guide 4213 and a lower air guide 4214, which facilitates injection molding.

[0039] Furthermore, the bottom of the upper air guide 4213 and the top of the lower air guide 4214 are provided with a second carding platform 4215 and a second carding groove 4216, respectively; the second carding groove 4216 cooperates with the second carding platform 4215.

[0040] Specifically, in this embodiment, the second slot 4216 cooperates with the second mounting plate 4215 to achieve quick installation and disassembly of the upper air guide 4213 and the lower air guide 4214. The structure is simple and the operation is convenient and quick.

[0041] With the use of fan 300, the air blown from the condenser 200 side is directed into the water tray body 410 after passing through the air guide component 420, effectively increasing the airflow speed and accelerating the defrosting water evaporation.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
