The present application also proposes a refrigerator 10, and it includes a cabinet 110, a water tray 410, and a water blocking assembly.

The interior of the cabinet 110 defines a cooling chamber 112. The water receiving tray 410 is located in the cooling chamber 112, and a water discharging hole 430 is formed at a bottom of the water receiving tray 410, and the water receiving tray 410 receives the defrosting water dropped from the evaporator 120 of the refrigerator 10 and discharges the defrosting water from the water discharging hole 430. The water blocking assembly is disposed at the water discharge hole 430, and includes a fixed portion 422 and a movable portion 424. The fixing portion 422 is connected to the bottom of the water tray 410 and disposed at the periphery of the drainage hole 430, the movable portion 424 is made of a heat-deformable material, and the movable portion 424 extends from the fixing portion 422 to the drainage hole 430, and is configured to be folded at a predetermined angle in a direction away from the drainage hole 430 to expose the drainage hole 430 after being heated to a predetermined temperature threshold.

In the present embodiment, the interior of the cabinet 110 defines a cooling chamber 112, and an evaporator 120 is generally disposed in the cooling chamber 112, and the evaporator 120 provides cooling energy to the refrigerator 10. The evaporator 120 often condenses water vapor in the air due to the low temperature thereon. The water tray 410 is disposed in the cooling chamber 112 and is used for receiving the condensed water or the defrosted water from the evaporator 120 to prevent the condensed water or the defrosted water from directly dripping on other components of the refrigerator 10 to cause adverse effects.

The drain hole 430 is provided on the water tray 410, and condensed water or defrosted water collected in the water tray 410 may be drained out of the cooling chamber 112 by the drain. In the present embodiment, in order to prevent the reverse flow of the external air from the drain hole 430 to the cooling chamber 112 and to cause an increase in power consumption and noise of the refrigerator 10, a water blocking assembly is provided at the drain hole 430. The water blocking assembly may achieve control of opening and closing of the drain hole 430, opening of the drain hole 430 when drainage is required, and closing of the drain hole 430 when drainage is not required.

The water blocking assembly includes a fixed portion 422 and a movable portion 424. The fixing part 422 is disposed at the periphery of the drain hole 430 and connected to the bottom of the water collector 410 to fix the relative position of the water blocking assembly and the drain hole 430, so that the water blocking assembly is more closely fitted to the drain hole 430 during operation.

In the present embodiment, the movable portion 424 is made of a heat-deformable material. The heat-deformable material is a material which changes its shape according to a certain deformation mode according to the temperature change on the material.

The movable portion 424 extends from the fixed portion 422 toward the drainage hole 430, and the movable portion 424 is folded away from the drainage hole 430 when the temperature of the movable portion 424 reaches a predetermined temperature threshold. In some embodiments of the present disclosure, the direction away from the drain hole 430 may be turned upward or downward by a predetermined angle relative to the drain hole 430 to expose the drain hole 430, and the drain hole 430 is in a drainage state, so that condensed water or defrosted water in the water-receiving tray 410 is drained from the drain hole 430.

When the drain pan 410 does not need to drain or the drain pan 410 does not collect condensed water or defrosted water, the temperature of the movable portion 424 may be controlled such that the movable portion 424 closes the drain hole 430 again due to a temperature change.

In some embodiments of the present disclosure, the active portion 424 may be a memory metal. The memory metal is a special metal material which can be plastically deformed in a certain temperature range and can restore the original macroscopic shape in another temperature range. In the present embodiment, the preset temperature threshold may be the lowest temperature at which the memory metal begins to deform, and a person skilled in the art may select the memory metal with the preset temperature threshold suitable for the temperature of the environment where the refrigerator 10 drains water, so that the opening and closing of the drain hole 430 may be controlled by controlling the preset temperature threshold.

The water blocking assembly controls the water discharge hole 430, and after the temperature of the movable part 424 is changed, the movable part 424 is deformed and folded to expose the water discharge hole 430 and start water discharge. Also, when the water discharge is not required, the temperature of the movable portion 424 is also changed to restore the movable portion 424 to its original position to close the water discharge hole 430.

In some embodiments of the application, the refrigerator 10 further includes an evaporator 120 and a heating element.

The evaporator 120 is disposed within the cooling chamber 112 above the drip tray 410 and is configured to cool the airflow entering the cooling chamber 112 to form a cooled airflow. The heating member is provided on the evaporator 120 for activating and transferring heat to the movable part 424 to open or close the water discharge hole 430 when defrosting the evaporator 120. The heating element is also thermally coupled to the evaporator 120 to directly or indirectly heat the evaporator 120 to melt frost on the evaporator 120.

The evaporator 120 serves as a cooling component of the refrigerator 10 to exchange heat with the airflow entering the cooling compartment 112, so as to reduce the temperature of the storage compartment of the refrigerator 10, thereby achieving the effect of refrigerating frozen food or other articles. In order to melt frost formed on the evaporator 120, a heating member is provided on the evaporator 120, and the evaporator 120 is heated at intervals according to a certain parameter. For example, when the temperature of the evaporator 120 is decreased when the compressor 200 starts to operate, the amount of the condensed water or the defrost water generated is large, and the heating member starts to perform heating defrosting. That is, the heating member is operated or stopped in synchronization with the compressor 200.

In the present embodiment, the heating member may also serve to transfer heat to the movable parts 424 to change the temperature of the movable parts 424, and to allow each of the movable parts 424 to open or close the water discharge holes 430 by changing the temperature thereof. Generally, when the compressor 200 starts to operate, the heating elements also start to operate synchronously, so that on one hand, defrosting can be started at a stage when the frost formation amount of the evaporator 120 is large, and at the same time, the defrosting water amount collected on the water pan 410 is also large at the stage, on the other hand, the heating elements transmit heat to the movable part 424 to enable the temperature of the movable part 424 to reach a preset temperature threshold value, and the movable part 424 starts to deform to open the drain hole 430.

That is, the heating member not only has a function of simultaneously transferring heat to the evaporator 120 and the movable portion 424, but also performs defrosting and opening of the drain hole 430 at the same time when the frost formation amount of the evaporator 120 is large, and stops defrosting and closing of the drain hole 430 at the same time when the frost formation amount of the evaporator 120 is small, thereby preventing the reverse flow of the outside air to the cooling chamber 112. Therefore, the heating wire 210 not only realizes defrosting and draining, but also meets the synchronization of defrosting and draining, produces unexpected technical effect, and has outstanding substantive characteristics and remarkable progress.

The press silo 114 is typically at a higher temperature, even higher than the outside temperature. The drain pipe 300 can guide the defrosting water and the condensed water collected by the water pan 410 to the evaporation pan 130 positioned in the press bin 114, and the defrosting water and the condensed water are evaporated in the evaporation pan 130 in a heat absorption manner, so that the defect that the evaporator 120 is frosted is overcome, the use experience of a user is improved, the water blocking component can block the drain hole 430, hot air cannot enter the cooling chamber 112 through the drain pipe 300 and the drain hole 430, and the energy consumption of the refrigerator 10 is optimized.

In some embodiments of the present disclosure, the bottom of the drip tray 410 is inclined toward the drain hole 430. The inclined bottom of the drip pan 410 may facilitate the condensed or defrosted water in the drip pan 410 to flow into the drainage hole 430 more smoothly. Those skilled in the art may tilt the entire water-receiving tray 410 to the drain hole 430, or may set the bottom wall of the water-receiving tray 410 to have a slope that is inclined toward the drain hole 430.
