detailed description

The core of this specific embodiment is to provide an electrical appliance with an air filter. When the filter assembly needs to be replaced, it can be automatically moved out and into the filter without disassembling the appliance, which is convenient.

Hereinafter, an embodiment will be described with reference to the drawings. In addition, the examples shown below do not limit the content of the utility model described in the claims in any way. In addition, all the content of the structure shown by the following embodiment is not limited to what is necessary as a solution of the invention described in a claim.

Please refer to FIG. 1-FIG. 6 , an electrical appliance with an air filter provided in this embodiment includes a body 11 , a filter assembly 12 and a drive assembly. It should be noted that the electrical appliance with the air filter may specifically be a fresh air fan, an air conditioner indoor unit, an air purifier, and the like. For the convenience of description, this article will take the new fan as an example to explain this solution.

The inside of the body 11 of the fresh air blower is provided with a filter installation position, and the filter assembly 12 is in the filter installation position when it is installed normally, so that the fresh air can filter the air through the filter assembly 12 .

In this way, in the technical solution provided by this embodiment, when the filter screen assembly 12 needs to be replaced, the drive assembly can be controlled to drive the filter screen assembly 12 from the filter screen installation position in the body 11 to the outside of the body 11, and then the filter screen assembly 12 for replacement, after the replacement is completed, control the drive assembly to drive the filter screen assembly 12 to reset to the filter screen installation position in the body 11. With such an arrangement, the replacement of the filter assembly 12 can be realized without manual disassembly of the body 11 , which is more convenient.

In a preferred solution of this embodiment, a panel of the body 11 is configured to be opened and closed, and a driving component is connected to the panel, and the panel can be opened or returned to its original position under the driving action of the driving component. The filter screen assembly 12 is connected with the panel. When the drive assembly drives the panel to open, the panel drives the filter screen assembly 12 out of the filter screen installation position. In this way, the filter screen assembly 12 connected to the panel can be disassembled and replaced , after the replacement is completed, the control drive assembly drives the panel to return to the original position, and under the drive of the panel, the replaced filter screen assembly 12 is displaced to the normal installation position.

It should be noted that since fresh air fans are usually installed in a hoisting or wall-mounted manner, in order to facilitate the replacement of the filter assembly 12, the above-mentioned openable and closable ground panel is the bottom panel 18 of the body 11, and the bottom panel 18 refers to the fresh air blower. When installed normally, it is the bottom panel.

In this way, when the bottom panel 18 is opened, that is, when the bottom panel 18 is displaced downward, the filter assembly 12 can be displaced downward by the bottom surface of the body 11 under the drive of the bottom panel 18, and the distance of the downward displacement can be determined according to The actual situation is specifically set. When the filter screen assembly 12 is lowered to a lower position, it is convenient to manually replace the filter screen assembly 12 .

Of course, the above-mentioned panel can also be other panels of the body 11, for example, the above-mentioned panel can also be the front panel of the fresh air machine, or when the above-mentioned electrical appliance with the air filter is other electrical appliances, such as, specifically, when it is an air purifier, the above-mentioned The panel can be left or right panel, which can be set according to the actual situation.

In order to improve the stability when the drive assembly drives the displacement of the panel, there can be at least two drive assemblies, and each drive assembly is respectively connected to different positions of the panel. In this way, different positions of the panel are driven by the drive assembly, which can Ensure that the panel has better stability during displacement.

Further, a guide post 13 can also be fixedly installed on the panel, and a guide groove cooperating with the guide post 13 is provided on the body 11. During the displacement process of the panel, through the limiting effect of the guide post 13 and the guide groove, the panel can be further improved. Stability during displacement.

Specifically, there may be two drive components, the positions where the panel is connected to the two drive components, and the positions where the guide posts 13 are arranged on the panel, and the three positions are distributed in a triangle. In such a setting, the support of the panel is a triangular support, which has better stability.

In addition, there can be multiple filter screen assemblies 12 in this embodiment, and each filter screen assembly 12 is connected to the above-mentioned panel. For example, the filter screen assembly 12 can include a coarse filter screen 20 and a high-efficiency filter screen 19. After the filtration of the coarse-effect filter screen 20, the filter of the high-efficiency filter screen 19 can be used to filter the air more thoroughly. Moreover, a plurality of filter screen assemblies 12 are all connected to the above-mentioned panel, and when the driving assembly drives the panel to open, multiple filter screen assemblies 12 can be replaced at the same time.

Each of the above-mentioned drive assemblies may include a motor 14, a gear connected to the output shaft of the motor 14, and a rack 15 meshed with the gear, wherein the rack 15 is connected to the panel. In such a configuration, when the motor 14 drives the gear to rotate, the gear drives the rack 15 to move along a straight line. Since the rack 15 is connected to the panel, it can drive the panel to move.

Of course, the above-mentioned drive assembly can also be of other types, for example, it can be a linear motor, a combination device of a motor and a screw nut, a combination device of a motor and a connecting rod, etc., as long as it can drive the linear displacement of the panel.

In order to make the rack 15 more stable during displacement, a rack guide groove 16 may be provided on the body 11 , and the rack 15 is slidably disposed in the rack guide groove 16 . Further, a ball device 17 is provided between the rack guide groove 16 and the opposite side of the rack 15 meshing with the gear. In this way, the sliding friction between the rack 15 and the rack guide groove 16 can be converted into rolling friction, effectively reducing the friction between the two.

In addition, in this embodiment, a sealing base that can be sealed with the filter assembly 12 can be provided on the panel. In this way, when the filter assembly 12 is installed on the sealing base on the panel, there is a gap between the filter assembly 12 and the panel. The sealed state can effectively avoid the problem of air leakage between the two.

In addition, it should be noted that in this embodiment, the body 11 can also be provided with an automatic door for the filter assembly 12 to enter and exit. When the drive assembly drives the filter assembly 12 to move out of the filter installation position to the outside of the body 11, the automatic door opens. ; When the drive assembly drives the filter assembly 12 to move to the filter installation position, the automatic door is closed.

With such arrangement, the automatic output and input of the filter pack 12 can also be realized. The automatic door may specifically include a door body, a travel switch, and a driving motor controlled by the travel switch. When the filter screen assembly 12 is output or input, the travel switch may be triggered, thereby controlling the opening or closing of the automatic door.

The above description of the disclosed embodiments enables those skilled in the art to realize or use the utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
