Description

TECHNICAL FIELD Embodiments of the present invention relate to the field of household appliance technologies, and in particular, to a packing mat for a household appliance and a household appliance. BACKGROUND Household appliances are generally subjected to additional external package protection to prevent damage caused by impacts to outer surfaces of the household appliances during handling. It is common practice in the industry to place a household appliance on a bottom mat for packing to provide buffer protection when the household appliance accidentally falls. Currently, for most bottom mat products on the market, hollow boards made of polypropylene (PP for short) are attached to foam bottom mats, or directly attached to bottom mats of expanded polystyrene (EPS for short) boards through an adhesive tape, which are used for bearing and transporting household appliances. In addition, to address inadequate protection during transportation, a density or a thickness of foam is often increased in a local region of the bottom mat (for example, a main load-bearing region on the bottom mat when the household appliance falls), or even elastic materials such as expanded polypropylene (EPP for short) are additionally provided to enhance bearing performance of the region. In this way, costs of components are increased, and the assembly process on the production line is complicated and manufacturing efficiency is low. On the other hand, foam particles may fall during transportation, and EPS foam bottom mats are difficult to recycle, which is to take hundreds of years to decompose, causing environmental pollution problems. SUMMARY An objective of embodiments of the present invention is to provide an improved packing solution for household appliances. Therefore, an embodiment of the present invention provides a packing mat for a household appliance, which supports at least one surface of the household appliance for packing. The packing mat includes a body made of a paper material. The body includes: a first support region, correspondingly supporting a first portion of the household appliance. Rigidity and/or strength of the first support region is greater than rigidity and/or strength of a remaining region of the body. Gravity borne by the first portion per unit area is greater than gravity borne by a remaining portion of the at least one surface per unit area. Compared with an existing packing solution using EPS, in this implementation, the packing mat is made of paper, which facilitates environmental protection while reliably protecting the household appliance. The body of the packing mat is enhanced in terms of rigidity and/or strength in a local region (for example, a region corresponding to the first portion of the household appliance), so as to achieve a better drop protection effect in the local region without additionally arranging elastic buffers. Specifically, the first support region has stronger load-bearing performance and is not easily broken during falling of the household appliance, thereby effectively improving the protective performance for the household appliance. Further, the first support region is a part of the body. The entire body is made of a paper material, which is green and environmentally friendly. Optionally, the first support region includes a plurality of first support ribs, the remaining region includes a plurality of second support ribs, and a distribution density of the plurality of first support ribs in the first support region is greater than a distribution density of the plurality of second support ribs in the remaining region. A denser arrangement of support ribs can improve the rigidity and/or strength of the first support region, so that the first support region is less prone to compression deformation than the second support region, thereby more reliably protecting the first portion of the household appliance. During falling of the household appliance, the first support region reliably supports the falling first portion through the first support ribs arranged with high density, thereby preventing the first portion from colliding with the ground and causing damage. Optionally, the first support region and the remaining region are formed integrally with the paper material. Therefore, a quantity of components included in the packing mat is reduced, so that a packing process is simplified during packing of the household appliance on a production line, thereby improving manufacturing efficiency. Further, the one-piece molding method eliminates the need for additional fixing materials (for example, adhesive tape), which is green and environmentally friendly. Optionally, the body is manufactured through a pulp molding process. Pulp molding is a three-dimensional paper-making technology, in which waste paper is usually used as raw material and a body is formed into the required shape through a plurality of processes. The entire manufacturing process is harmless to the environment, and
