Abstract

The utility model relates to a freezer with a defrosting and draining device installed on an inner shell at the bottom of a freezer box. The utility model is characterized in that the main body of the defrosting and draining device is a drainpipe provided with an upper end orifice with an outward turning edge. A downward turning orifice matched with the size of the inside diameter of the upper end orifice is arranged in the inner shell of the freezer. The upper end orifice is sleeved on the turned down orifice. The lower end of drainpipe is positioned on a baseboard of the freezer through a ring shaped baffle. The upper end orifice is provided with a detachable airproof drain cover. The inner wall of the upper end orifice is provided with a screw thread for the drain cover to make the inclined planes of the drain cover, the inner shell and the drainpipe matched with each other more tightly. The utility model can realize the effective drain function, use few components and enhance the service valve of the water inlet of the draining device of the freezer. Besides, the utility model greatly saves the material utilization and decreases the product cost.

Description

A kind of refrigerator that has the defrost drainage arrangement

Technical field

The utility model relates to a kind of refrigerator that has the defrost drainage arrangement.

Background technology

At present, be used to deposit various food, cold drink,, after use a period of time, can in cabinet, freeze or frosting, make refrigerating efficiency descend as the refrigerator and the horizontal showcase of ice cream, ice cream etc., so, need clear up cabinet according to circumstances, carry out defrost.Usually, drainage arrangement is installed, is mainly used in the outside that the water that will form after the defrost in the cabinet is discharged cabinet at refrigerator and horizontal showcase bottom of cabinet bulk.And the water inlet of common refrigerator drainage arrangement, the structural design more complicated, used part is more, and not only cost is higher, and what have is bad because of cooperating between the part, has also had influence on practical effect.

The utility model content

At the problems referred to above, the purpose of this utility model is to provide a kind of refrigerator that has the defrost drainage arrangement, with under the situation of using less part, realizes the function of draining well.

To achieve these goals, the technical solution of the utility model has been to adopt a kind of refrigerator that has the defrost drainage arrangement, the defrost drainage arrangement is installed on the bottom inner casing of refrigerator box body, the main body of this defrost drainage arrangement is a drainpipe, drainpipe has one and has the outer upper port that turns edge, on the cabinet inner casing, be provided with the upper port internal diameter size and descend turned welt accordingly, the corresponding cover of upper port is inserted in down on the turned welt, the lower end of drainpipe is positioned on the cabinet base plate by an annular catch, is equipped with removable sealing drain cap on upper port.

Described drain cap screw thread is assemblied on the inwall of upper port.

The cap body of described drain cap is provided with disassembly and assembly structure.

Described disassembly and assembly structure is one flat mouthful of nut structure.

The cap body of described drain cap is corresponding countersunk head structure with the cabinet inner casing of corresponding position.

Adopt refrigerator of the present utility model, during use, the drain cap that screws on the drainpipe upper port is removed, defrost then, the water of defrost will flow out along the water inlet of this drainage arrangement.The drain cap screw thread is assemblied on the inwall of upper port of drainpipe, make the more tight refrigerator of the present utility model of cooperation on inclined-plane of the inclined-plane of inclined-plane, inner casing of drain cap and drainpipe can either realize effective drain function, used part is few simultaneously, improved the use value of refrigerator drainage arrangement water inlet effectively, the utility model has been saved the use of material greatly, has reduced production cost.
