Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, for example, to an inner tank assembly and a refrigerator. Background Art

[0002] The refrigerator liner is provided with a drain port for draining the condensed water in the liner. In order to drain the condensed water in the liner into the water receiving tray, a drain pipe is connected to the drain port, and the condensed water is led into the water receiving tray through the drain pipe.

[0003] In the related art, in order to improve the stability of the connection between the drain pipe and the inner tank, the drain pipe is fixed to the inner tank by sticking tape.

[0004] In the publicly available implementation process, there are at least the following problems:

[0005] The installation method of the drain pipe is inefficient. The drain pipe is at the front processing end, and additional tape needs to be pasted. The release paper needs to be torn off and pasted on the bottom of the inner tank for assembly. There are many steps and there is a risk of leakage if the tape is not applied evenly. It is easy to freeze and block the drain port under long-term use, causing adverse effects on the refrigeration system. In addition, if the tape is not applied evenly, it will affect the sealing of the structure and cause the risk of leakage.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.
