That is, the guiding rail structure <NUM> is detachably connected to the face frame <NUM> through the connecting member <NUM> and/or the first guiding member <NUM> and/or the second guiding member <NUM>. The connecting member <NUM> and the first guiding member <NUM> and the second guiding member <NUM> as a whole are detachably connected to the face frame <NUM>. In the present embodiment, the connecting member <NUM> may be a plate-like structure or a block-like structure, and the connecting member <NUM> functions as a mounting, fixing, supporting, and connecting. When the guiding rail structure <NUM> is mounted on the face frame <NUM>, in order to prevent the connecting member <NUM> from affecting the amount of air entering the air inlet <NUM>, optionally, the connecting member <NUM> is a plate-like structure.

As shown in <FIG>, <FIG> and <FIG>, the embodiment further provides an indoor unit of an air conditioner <NUM>, including a chassis <NUM>, a face frame assembly <NUM> connected to the chassis <NUM>, and a filter screen <NUM>. The specific structure of the face frame assembly <NUM> is referred to the above embodiments. Since the indoor unit of the air conditioner <NUM> adopts all the technical solutions of all the above embodiments, at least the effects brought by the technical solutions of the foregoing embodiments are not described herein.

Specially, the face frame assembly <NUM> is the above-described face frame assembly <NUM>, and the chassis <NUM> is cooperated with the face frame assembly <NUM> to form a mounting cavity. The guiding rail structure <NUM> is located within the mounting cavity, and the filter screen <NUM> is movably mounted on the sliding rail <NUM> and is located near the air inlet <NUM>.

It should be understood that, as shown in <FIG>, a limiting baffle <NUM> is protruded from one end of the filter screen <NUM>. The arrangement of the limiting baffle <NUM> facilitates the operator to remove the filter screen <NUM> from the face frame <NUM> through the limiting baffle <NUM> on the filter screen <NUM> at the filter screen mounting opening <NUM>. Of course, when the filter screen <NUM> is mounted in the air inlet <NUM> of the face frame <NUM>, the limiting baffle <NUM> is abutted against the inner wall of the filter screen mounting opening <NUM>.

In the embodiment, the indoor unit of the air conditioner <NUM> can have either a function of automatically cleaning the filter screen or a function of manually cleaning the filter screen. When the indoor unit of the air conditioner <NUM> has the function of automatically cleaning the filter screen, a cleaning assembly <NUM> is further disposed in the mounting cavity of the indoor unit of the air conditioner <NUM>. At this time, the guiding rail structure <NUM> is not mounted in the air inlet <NUM> of the face frame <NUM>, the filter screen <NUM> is mounted in the air inlet <NUM> of the face frame <NUM>, and the cleaning assembly <NUM> can drive the filter screen <NUM> to move and clean the filter screen <NUM>. When the indoor unit of the air conditioner <NUM> has the function of manually cleaning the filter screen, the cleaning assembly <NUM> is not disposed in the mounting cavity of the indoor unit of the air conditioner <NUM>. At this time, the guiding rail structure <NUM> is mounted in the air inlet <NUM> of the face frame <NUM>, the filter screen <NUM> may be mounted in the air inlet <NUM> of the face frame <NUM> from the sliding rail <NUM> of the filter screen mounting opening <NUM> via the sliding rail <NUM> of the guiding rail structure <NUM>. When the filter screen <NUM> needs to be disassembled, the filter screen <NUM> is removed from the air inlet <NUM> of the face frame <NUM> through the sliding rails <NUM> of the guiding rail structure <NUM> from the slide <NUM> through the limiting baffle <NUM> of the filter screen <NUM>.

The embodiment further provides a face frame <NUM>. The specific result of the face frame <NUM> can be referred to <FIG>, <FIG>, <FIG>, <FIG>, and <FIG>, and the face frame <NUM> includes a filter screen mounting structure. Specifically, the face frame <NUM> has a frame structure or a cover structure, and the face frame <NUM> includes an air inlet <NUM> and a filter screen mounting opening <NUM> which are spaced apart. That is, the upper side of the face frame <NUM> has an air inlet <NUM>, and the front side of the face frame <NUM> has a filter screen mounting opening <NUM>. The face frame <NUM> is further provided with an air inlet grille <NUM> near the air inlet <NUM>, that is, the air inlet grille <NUM> is integrally formed at the air inlet <NUM> of the face frame <NUM>.

Specially, the filter screen mounting structure includes a first mounting structure in the air inlet and a second mounting structure in the filter screen mounting opening. It can be understood that the filter screen mounting structure is composed of two parts of the first mounting structure and the second mounting structure. That is, one end of the first mounting structure is detachably connected to one end of the second mounting structure, and one end of the first mounting structure is abutted against one end of the second mounting structure to make the filter screen mounting structure as a whole. In the present application, the first mounting structure may be the above-mentioned guiding rail structure <NUM>, or may be a structure in which the filter screen is installed, which is not limited herein.

Further, the filter screen mounting structure has a mounting space for the filter screen <NUM> to be mounted. The mounting space may be a space structure formed by the filter screen mounting structure itself, or a space structure formed by the cooperation of the filter screen mounting structure and the air inlet grille <NUM>, which is not limited herein. Specifically, the first mounting structure is formed with a sliding rail <NUM>, and the second mounting structure is formed with a slide <NUM>. When one end of the first mounting structure is abutted against one end of the second mounting structure, the sliding rail <NUM> and the slide <NUM> communicate to define the mounting space for the filter screen <NUM> to be mounted.

The face frame <NUM> connects the first partial mounting structure in the air inlet <NUM> to the face frame <NUM> by splitting the filter screen mounting structure into two parts. As such, the face frame <NUM> can automatically clean the filter screen or manually clean the filter screen, which improves the utilization and production efficiency of the face frame <NUM> mold, simplifies the production process, and reduces the production cost. Besides, the first mounting structure in the air inlet <NUM> and the second mounting structure in the filter screen mounting opening <NUM> are used to facilitate manual disassembly and cleaning of the filter screen, thereby improving the convenience of use of the face frame <NUM>.

As shown in <FIG>, <FIG> and <FIG>, the present disclosure further provides an indoor unit of an air conditioner <NUM>, including a chassis <NUM>, a face frame <NUM> connected to the chassis <NUM> and a filter screen <NUM>. The specific structure of the face frame <NUM> is referred to the above embodiments.
