Background The air conditioner is an electric appliance commonly used in daily life of people, and the air conditioner with the fresh air function is gradually popularized and used along with the improvement of the requirement of users on the air quality. An air conditioner having a fresh air function is generally additionally provided with a total heat exchange core through which indoor and outdoor air is satisfied. Chinese patent publication No. CN 220582674U discloses a total heat exchanger, in which a fan and a heat exchange core are disposed inside a housing, and a filter is disposed in the housing to filter air entering the heat exchange core in order to filter air entering the heat exchange core. In order to facilitate replacement of the filter, a switchable access cover is generally arranged on the housing, and the heat exchange core can be exposed at the maintenance opening by opening the access cover to expose the maintenance opening of the housing, and meanwhile, an operator can assemble and disassemble the filter through the maintenance opening. In the actual use process, the filters configured on the heat exchange core body are different according to different air sources flowing in, specifically, the filters configured on the air entering the heat exchange core body from indoor return air generally adopt a coarse filter screen, and the filters configured on the air entering the heat exchange core body from outdoor fresh air generally adopt a mode of combining the coarse filter screen with a high-efficiency filter screen. And limited by the size of the service port, the prior art filters are smaller in size to meet the requirements for removal from the service port. Particularly, the filter for filtering the indoor return air has smaller overall length, so that the coverage area of the filter is smaller. In view of this, how to design a technology for improving the coverage of a filter and meeting the requirement of convenient disassembly and assembly is a technical problem to be solved by the utility model. The above information disclosed in this background section is only for enhancement of understanding of the background section of the application and therefore it may not form the prior art that is already known to those of ordinary skill in the art.
