Description

CROSS REFERENCE TO RELATED APPLICATIONS This application is a continuation application of PCT International Patent Application No. PCT/CN2020/129247, filed on Nov. 17, 2020, which claims priority to and benefits of Chinese Patent Application No. 202010241373.3, titled “WALL-MOUNTED AIR CONDITIONING INDOOR UNIT AND AIR CONDITIONER” and filed with the Chinese Patent Office on Mar. 30, 2020. The entire contents of the aforementioned applications are incorporated in this application by reference for all purposes. No new matter has been introduced. FIELD This application relates to the field of air conditioners, and in particular, to a wall-mounted air conditioning indoor unit and an air conditioner. BACKGROUND The current air conditioner only circularly heats or cools the indoor air when heating or cooling, and meanwhile, in order to maintain the indoor temperature, the user will close the door of the room at the same time, which will gradually deteriorate the indoor air quality and do harm to the user's health. In particular, in recent years, the air pollution is getting worse and worse, especially in the period of supplying heating in winter, and people are reluctant to open windows for ventilation. As such, the indoor air quality will deteriorate, and the level of oxygen contents in the indoor air will decrease, which harms the health of users. In the related technology, the fresh air device has been introduced into the air conditioning indoor unit. Since the fresh air inlet is kept open, the outdoor cold air will directly enter the fresh air device in cold seasons, resulting in the internal structures of the fresh air device being frozen due to long-term exposure to cold air, and the reduction of the service life of the fresh air device. SUMMARY An object of this application is to provide a wall-mounted air conditioning indoor unit, which aims at solving at least the technical problem of how to prolong the service life of fresh air module.
