Detailed ways

The core of this application is to provide a filter structure and an indoor unit to solve the problem of inconvenient removal of the filter of the indoor unit.

In order to enable those skilled in the art to better understand the technical solutions provided by the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described The embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

In the description of this application, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left" and "right" are based on the drawings shown The orientation or positional relationship is only for the convenience of describing the application and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of this application.

As shown in Figures 1 and 2, a filter structure provided by an embodiment of the present application is applied to an indoor unit of an air conditioner, and includes a filter installation channel 2 provided on the indoor unit 1 and a filter installation The filter screen 3 in the channel 2. The filter screen installation channel 2 includes at least one installation opening 20. The filter screen 3 can be slid into and out of the installation channel 2 from the installation opening 20, and the filter screen 3 is close to the installation opening in the installed state One side of 20 is provided with an extension part 4 extending below the indoor unit 1 for the user to directly pull out the filter screen 3.

When the filter structure needs to be cleaned and disassembled, the user does not need to step on the stool or open the panel. Just pull the extension directly to drive the entire filter to slide along the filter installation channel, and the filter is outward from the installation port. Slide, and finally slide out of the filter installation channel, which greatly improves the convenience of taking out the filter of the indoor unit.

It is worth mentioning here that the installation port 20 on the filter installation channel 2 can be one or more, but it should be ensured that there is at least one installation port, so as to ensure the normal sliding in and out of the filter.

It should be noted that, generally speaking, the value range of the distance between the end of the extension part 4 and the indoor floor can be 0-160 cm. This is because for household air conditioners, the installation height of the indoor unit 1 is generally about 2 meters, and by designing the extension 4 to be 0-160 cm from the ground, most normal adults can take the extension. Department. Of course, it can be understood that in the actual application process, it can also be designed to be more than 160 cm according to user needs. Generally speaking, for the indoor height of most houses, the extension 4 is designed to extend about 40 cm to the bottom of the indoor unit to facilitate the direct pulling needs of most users.

In a further embodiment, the end of the extension 4 may also be provided with a handle 41. For example, when the extension part is suspended below the indoor unit, the handle is designed to make it more convenient for the user to grasp the extension part.

In some more specific embodiments, the structure of the above-mentioned filter installation channel 2 may specifically include a transverse installation channel 21 provided on the top of the indoor unit 1 and at least one of the left side and the right side of the indoor unit 1. The longitudinal installation channel 22 on the side, the horizontal installation channel 21 and the longitudinal installation channel 22 intersect, the installation port 20 is arranged at the lower end of the longitudinal installation channel 22; the filter screen 3 is a flexible filter screen and part of it is installed in the horizontal In the channel 21, the other part is located in the longitudinal installation channel 22. It should be noted that the layout structure of the filter installation channel is selected and set according to the requirements of the filter layout position. For example, a horizontal installation channel can also be designed only on the top of the indoor unit. At this time, the corresponding filter The net is only arranged at the top. However, this application is designed in the form of a horizontal installation channel and a vertical installation channel, on the one hand, to make the coverage of the filter more comprehensive and more helpful to filter dust, on the other hand, it is designed into the form of a horizontal installation channel and a vertical installation channel. It is more convenient to pull the filter directly downwards, which can effectively avoid jams.

In a further embodiment, in order to ensure the good operation of the electrical box 5 in the indoor unit 1 and prevent dust from entering the electrical box, generally speaking, the longitudinal installation channel 22 should at least be located near the electrical box 5 in the indoor unit 1. Design on the side, as for the side without the electrical box, it can be selectively designed according to requirements.

In some more specific embodiments, in order to enable the filter 3 reinstalled in the filter installation channel 2 to stably stay in the filter installation channel 2, generally, a damping device may also be provided in the filter installation channel 2. The transmission gear 6 is provided with a toothed structure meshing with the transmission gear 6 on the filter screen 3. The meshing of the transmission gear 6 with the toothed structure on the filter screen 3 realizes the fixation and limitation of the filter screen in the installation channel of the filter screen. It should be noted that the transmission gear 6 with damping can be realized by having a certain frictional resistance between the transmission gear and its rotating shaft, or realized by other ways known to those skilled in the art that can bring damping, here Do not make specific restrictions.

In addition, it should be noted that the above-mentioned method of using the transmission gear to realize the filter screen fixed in the filter screen installation channel is only a preferred example of the embodiment of the present application. In the actual application process, it can also be installed through the filter screen and the filter screen. The channel sliding fit has a certain frictional resistance to achieve.

In addition, it should be noted that the above-mentioned tooth-like structure can be specifically arranged on the lower surface of the filter screen 3, and of course can also be designed on the upper surface of the filter screen. In the actual application process, the layout can be selected according to the actual layout requirements.

In a further embodiment, when the filter installation channel 2 is formed by the horizontal installation channel 21 and the longitudinal installation channel 22, in order to make the joint position where the horizontal installation channel 21 and the longitudinal installation channel 22 pass through, slide more smoothly and avoid jams. Generally, it is preferable to design the transmission gear 6 at the junction corner of the horizontal installation channel 21 and the longitudinal installation channel 22. Of course, the toothed structure provided on the corresponding filter screen 3 should be set on the lower surface of the filter screen 3 at this time.

In a further embodiment, in order to avoid the problem of jamming at the corners of the horizontal and longitudinal installation channels when the filter screen 3 is installed into the filter screen installation channel 2, the above-mentioned transmission gear 6 can also be connected with Drive mechanism. When the filter screen is installed in the filter screen installation channel and reaches the corner of the horizontal installation channel and the longitudinal installation channel, the drive gear can be driven to rotate through the drive mechanism, and then the filter screen can be driven through the corner, which greatly improves the installation time Convenience.
