Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The application provides a drainage structure, as shown in fig. 1 and 2, which comprises a water receiving tray 1, a drainage outlet 2, an anti-blocking cover 3 and a heater 4.

The water pan 1 is arranged below the evaporator 5, the heater 4 is an electric heater, the heater 4 comprises a steel pipe, and the steel pipe is connected with the evaporator 5 and used for transferring heat to the evaporator fins and the pipeline.

The water pan 1 is arranged below the evaporator 5, when frost on the surface of the evaporator 5 is heated and melted, the melted water or the falling ice blocks fall into the water pan 1, the water pan 1 is provided with a water outlet 2, the heater 4 is used for heating by electrifying, the heat of the heater 4 is transferred to a frost layer by means of heat radiation and heat convection, the frost water is formed into water which falls into the water pan 1 at the bottom of the freezing liner, or the ice is formed into small ice blocks which fall into the water pan and is continuously heated and formed into water, and the frost water in the water pan flows through the water outlet at the bottom of the water pan and is discharged from the water outlet 2.

Further, as shown in fig. 3, the water receiving tray 1 includes a water drainage groove 11, the water outlet 2 is arranged at the middle position of the bottom of the water drainage groove 11, the cross street area from the water outlet 2 to the opening of the water drainage groove 11 is gradually increased, the water flow and the ice cubes are guided, and the water drainage effect is accelerated.

In this embodiment, the bottom surface of the drainage channel 11 is inclined, and the drainage outlet 2 is arranged at the lowest position of the horizontal position of the drainage channel 11, specifically, the bottom surface of the drainage channel 11 is arranged in a V shape, so that the drainage effect is further ensured.

An anti-blocking cover 3 made of heat conducting materials is arranged on the water outlet 2 and used for blocking larger ice blocks outside the anti-blocking cover 3; the steel pipe of heater 4 is the V font, thereby prevents that the most advanced of stifled cover 3 and steel pipe middle part contacts to prevent stifled cover 3 surfaces with heat transfer, prevents stifled cover 3 and melts its nearby ice-cube, makes the effluvium discharge fast.

Further, as shown in fig. 4 and 5, the anti-blocking cover 3 is detachably mounted on the drain opening 2, the drain opening 2 is recessed downward from the bottom surface of the drain groove 11 by a certain depth to form a circular bottom 21 and a side wall 22 of the drain opening 2, and the bottom 21 is provided with a drain hole for draining water.

As shown in fig. 6, the anti-blocking cover 3 includes an end portion 31 contacting with the heater 4, an opening portion 32 and bars 33, one end of a plurality of bars 33 is connected with the end portion 31 and extends out from the end portion 31 in one direction, the bars 33 are arranged in a circle, the direction of the bars 33 far away from the end portion 31 is enclosed to form the opening portion 32, the end portions of the bars 33 located at the opening portion 32 are connected and fixed by annular bars one by one, and the area of the anti-blocking cover 3 from the end portion 31 to the opening portion 32 is gradually increased.

When the installation, will prevent stifled opening 32 disect insertion to lateral wall 22 of cover 3, and the shape and size that opening 32's shape and lateral wall 22 enclose, the size is corresponding, make prevent stifled cover 3 direct can the disect insertion to lateral wall 22, the metal prevents stifled piece and top and defrosting heater contact, fall near the outlet when incomplete ice, can be given the heat of preventing stifled cover 3 by heater 4 and melt, thereby stop because of depositing between water collector and the freezing courage and the stifled risk of ice that the incomplete ice falls into the outlet and cause, and when silt of outlet 2 department piles up to certain degree, will prevent stifled cover 3 and extract and clear up.

Furthermore, an annular reinforcing bar 34 is arranged in the middle of each grid 33 to connect and fix the grids 33 together, so as to reinforce the structural strength of the anti-blocking cover 3.

Further, a round chamfer is provided at the junction of the upper portion of the side wall 22 and the bottom surface of the drain tank 11, thereby facilitating the removal and installation of the anti-blocking cover 3.

The application also discloses a refrigerator, which comprises the drainage structure disclosed by the application.
