Description

TECHNICAL FIELD Embodiments of the present disclosure relate to the field of household appliance technologies, and specifically, to a packaging cushion for a household appliance, a household appliance, and a method for manufacturing a packaging cushion. BACKGROUND During transportation, a household appliance is usually additionally packaged and protected on the outside to avoid damage caused by impact on the external surface of the household appliance during handling. At present, during the handling of a household appliance, a top cover (and/or a bottom cushion) made of an expanded polystyrene board (EPS for short) material is usually used to protect a periphery of a top (and/or a periphery of a bottom) of the household appliance. However, the EPS material is not environmentally friendly, foam particles may fall down during transportation, and it is difficult to recycle and process an EPS foam top cover, which requires hundreds of years to decompose, causing environmental pollution problems. On the other hand, the protection for the top and/or the bottom of the household appliance by the existing EPS foam top cover is concentrated on the top surface and/or the bottom surface, and the protection for the side surface of the household appliance close to the top and/or the bottom is relatively weak. SUMMARY An objective of embodiments of the present disclosure is to provide an improved packaging solution for a household appliance. Therefore, the embodiments of the present disclosure provide a packaging cushion for a household appliance. The household appliance includes a main body defining a chamber and a door configured to close the chamber. The packaging cushion wraps a top or a bottom of the household appliance. The packaging cushion includes: a first plate, at least configured to cover a top surface or a bottom surface of the main body, a rim on at least one side of the first plate being folded to form a side portion provided with a cavity, and the side portion being configured to cover at least part of a side surface of the main body; and a protective member, filled in the cavity. Compared with an existing packaging solution using EPS, in this implementation solution, the top surface or the bottom surface of the household appliance is protected by the first plate, and the side portion provides targeted protection for the side surface of the household appliance close to the top or the bottom, which is beneficial to more reliable protection of the household appliance. When the household appliance is inclined during handling, the cooperation of the side portion and the first plate can protect corners and edges of the top or the bottom of the household appliance in an all-round way, thereby better preventing the household appliance from impact and damage. Further, the side portion is formed by folding of the flange of the first plate, that is, the side portion and the first plate are the same member, so that the packaging cushion has a small quantity of parts and is easy to manufacture and assemble. Further, the cavity of the side portion is prevented from springback and deformation in the manner of filling the protective member, to ensure flat crush strength of the overall structure of the flange, thereby effectively protecting the periphery of the top or the bottom of the household appliance. Optionally, the side portion extends at least partially around the first plate. Therefore, at least part of the periphery of the top or the bottom of the household appliance can be reliably protected. Optionally, the rim on the at least one side of the first plate first extends along a first direction and then extends back to the first plate to form the cavity, a non-zero angle being formed between the first direction and a plane in which the first plate is located. Therefore, the first plate is self-folded to form the side portion, and an integral design is beneficial to reducing an assembly error and simplifying an assembly process. Further, the design of the cavity enables the side portion to have a particular thickness, so that when being impacted by an external force, the side portion can serve the functions of cushioning and shock absorption, thereby better protecting the side surface of the household appliance. Optionally, the protective member and the first plate are separately made of paper materials of different structures. Therefore, manufacturing of the packaging cushion using paper is beneficial to environmental protection while effectively protecting the top or the bottom of the household appliance. Further, the characteristic of the paper material enables the side portion to be more easily folded and formed, thereby reducing processing difficulty of the packaging cushion and facilitating manufacturing. Further, the protective member and the first plate are separately manufactured using more suitable paper materials, and can better achieve the functions of the components. For example, the first plate is ma
