Description

The present application is based on a Chinese patent application with application number 202310799782.9, filed on June 30, 2023, and claims the priority of the Chinese patent application, the entire content of which is incorporated herein by reference. TECHNICAL FIELD The present application relates to a field of refrigeration, and particularly relates to a refrigerator. BACKGROUND Currently, for most built-in refrigerators, a control system assembly for controlling an operation of refrigerator electrical components is integrated at a top of a refrigerator, either by opening a hole at a top of a housing and adding a plastic box to accommodate the control system assembly; or by opening a hole on a front side of the housing and installing a control board bracket into the refrigerator, and then assembling a display mask or a decorative cover on an outside for covering. An operation is complex, time-consuming and labor-intensive, and inconvenient for subsequent disassembly and maintenance. Any related art mentioned in the description does not indicate confirmation or suggestion that the related art constitutes part of common knowledge in any jurisdiction, or that the related art can be reasonably expected to be understood, regarded as relevant and/or combined with other related art by those skilled in the art. SUMMARY An object of the present application is to provide a refrigerator to solve the technical problem of a complex control system assembly in the related art.
