Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the priority, under 35 U.S.C. § 119, of Chinese Patent Application CN 202411558772.7, filed Nov. 1, 2024; the prior application is herewith incorporated by reference in its entirety. FIELD OF THE INVENTION 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 OF THE INVENTION 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 that 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, and take hundreds of years to decompose, causing environmental pollution problems. SUMMARY OF THE INVENTION It is accordingly an object of the invention to provide a packing mat for household appliances and a household appliance, which overcome the hereinafore-mentioned disadvantages of the heretofore-known devices of this general type and which provide an improved packing solution for household appliances. With the foregoing and other objects in view there is provided, in accordance with the invention, 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 buffer support region, corresponding to a support portion of the household appliance. A non-zero gap is defined between the buffer support region and the support portion to absorb potential energy generated by downward movement of the support portion. The support portion includes a support plate of a compressor compartment. The support plate is configured to support a compressor. Compared with an existing packing solution using EPS, in this implementation, the packing mat is made of paper, which facilitates environmental protection while effectively protecting the household appliance. The packing mat is provided with the buffer support region. The buffer support region does not play an actual supporting role when the household appliance in a packed state is normally placed. For example, during a falling test, the support portion of the household appliance moves downward due to falling, and a gap between the buffer support region and the support portion gradually decreases until in contact with each other. In this case, potential energy generated through falling of the support portion is absorbed by the buffer support region, thereby implementing reliable protection for the household appliance (especially the support portion) during the falling test. Further, the buffer support region is a part of the body. The entire body is made of a paper material, which is green and environmentally friendly. Further, the support portion of the household appliance is configured to support most of the weight of the household appliance, and therefore requires special protection when the household appliance falls. In the packing mat provided in this implementation, the buffer support region is specially disposed for the support portion, which plays a buffer role when the household appliance falls, to avoid causing an adverse effect due to excessive rigidity of the body, and provide flexible support for the support portion. Therefore, the body has both better bearing performance and buffer performance, which can provide a better protection effect for the household appliance. Optionally, the buffer support region includes a peripheral region, and a middle platform region recessed from the peripheral region and at least partially surrounded by the peripheral region. If a support region is formed by a large plane, the support region has strong rigidity, which is not beneficial to absorb the potential energy during the falling of the household appliance. B
