Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a dust removal device and an air conditioner. Background Art

[0002] There are many air conditioners in the prior art that can prevent dust accumulation on the filter screen of the air inlet, but such air conditioners in the prior art still have defects. Take the following two air conditioners as examples:

However, with this type of air conditioner, the filter remains at the air inlet regardless of whether the air conditioner is in use. Consequently, dust and dirt accumulate on the filter when the air conditioner is not in use, and dust may even pass through the filter and enter the evaporator and air duct.

[0004] The second type of air conditioner includes an air vent assembly that prevents dust from settling in the air inlet when the air conditioner is not in use. The air vent assembly includes a flexible baffle connected to a filter screen. The flexible baffle is retractable so that the filter screen and the flexible baffle can be selectively positioned to block the air inlet. However, while this air conditioner can prevent dust from entering the evaporator and the air duct, it cannot clean the dust on the flexible baffle. After the air conditioner has been stationary for a long time, dust easily accumulates on the flexible baffle. This easily causes dust accumulation when the flexible baffle is reeled up, and the flexible baffle suffers from a problem of asynchronous reeling along the distribution direction of the filter screen and the flexible baffle.

[0037] The dust removal device of the present invention includes a shielding assembly 10 and a cleaning assembly 20. The shielding assembly 10 is used to be arranged at the vent 100. The shielding assembly 10 includes a filter 11 and a baffle 12 connected to each other. By moving the shielding assembly 10, the filter 11 and the baffle 12 can be selectively shielded at the vent 100. In this way, when the air conditioner is not working, the baffle 12 can shield the vent 100 to prevent external dust from falling into the interior of the air conditioner. In addition, the cleaning assembly 20 in the present application contacts the shielding assembly 10 so that when relative movement occurs between the cleaning assembly 20 and the shielding assembly 10, the dust on the shielding assembly 10 is cleaned by the cleaning assembly 20. In this way, the dust generated on the baffle 12 due to the air conditioner being stationary for a long time can be cleaned by the cleaning assembly 20, so that the baffle 12 is reeled synchronously along the distribution direction of the filter and the flexible baffle, thereby solving the problem that the dust at the baffle of the vent of the air conditioner in the prior art is difficult to clean, and realizing automatic cleaning of the baffle of the vent.

[0044] Specifically, the retaining rib ridge 120 contacts the inner wall surface of the upper shell of the installation shell 30 close to the vent 100, so that a stop space is formed on the side of the retaining rib ridge 120 away from the vent 100 to prevent the airflow of the vent 100 from affecting the dust in the stop space when the air conditioner is running.

[0045] Specifically, the retaining rib ridges 120 are made of a flexible material.

[0046] In an embodiment of the present invention, the cleaning assembly 20 includes a first cleaning component 21 and a second cleaning component 22 , and the first cleaning component 21 and the second cleaning component 22 are respectively arranged at both ends of the vent 100 along the movement direction of the shielding assembly 10 .

[0048] like Figure 7 and Figure 8 As shown, the main part of the mounting shell 30 includes a first guide rail 310 and a second guide rail 320. The first guide rail 310 is located above the second guide rail 320. The first guide rail 310 and the second guide rail 320 are spaced apart. When the filter screen 11 blocks the vent 100, the filter screen 11 is located in the first guide rail 310.

[0049] Specifically, the dust removal device further includes: a shielding drive assembly 40 , which is drivingly connected to the shielding assembly 10 to drive the baffle 12 and the filter 11 of the shielding assembly 10 to selectively shield the vent 100 .

[0050] Specifically, the shielding drive assembly 40 includes a first drive component 41 and a second drive component 42, and the first drive component 41 and the second drive component 42 are respectively arranged at both ends of the mounting shell 30 of the dust removal device. The first drive component 41 is connected to the filter 11, and the second drive component 42 is connected to the baffle 12; wherein, the first drive component 41 and the second drive component 42 move synchronously and have the same driving direction.

[0051] Specifically, the first driving component 41 has a roller component 410, the outer surface of the roller component 410 is provided with meshing teeth 411, the inner wall surface of the filter screen 11 is provided with meshing protrusions 111, and the meshing teeth 411 are engaged with the meshing protrusions 111; and / or the second driving component 42 includes a reel component 420, the baffle 12 is a flexible plate, and the reel component 420 is connected to one end of the baffle 12 away from the filter screen 11 so as to reel or release the baffle 12 by rotating the reel component 420.

[0052] Specifically, the baffle 12 is a flexible PET plate.

[0053] Specifically, meshing gears are provided at both ends of the drum component 410, and the meshing teeth 411 of the meshing gears cooperate with the meshing protrusions 111.

[0054] During the specific implementation of the embodiment of the present invention, when the air conditioner is in working state, the second driving component 42 rotates and reels clockwise, and the first driving component 41 rotates clockwise, driving the shielding assembly 10 to move in the first guide rail 310 and the second guide rail 320 of the mounting shell 30, and the baffle 12 moves toward the direction close to the second driving component 42. At this time, the second cleaning component 22 is in close contact with the baffle, and the dust on the baffle 12 is swept to the connecting section 13 between the baffle 12 and the filter 11, and is located on the side of the second cleaning component 22 close to the filter 11. At this time, the filter 11 moves from the second guide rail 320 to the first guide rail 310 until the filter 11 completely covers the vent 100, and then stops rewinding.

[0055] Specifically, the second driving component 42 is activated earlier than the first driving component 41 , and the first driving component 41 is 0.1 seconds faster than the second driving component 42 to ensure that the flexible baffle and the filter screen are in a tensioned state.

The filter 11 moves within the first guide rail 310 toward the first drive component 41, and is rolled into the second guide rail 320 by the roller component 410. The first cleaning component 21 simultaneously rotates clockwise, sweeping dust from the filter 11 into the dust collection box until the dust from the connecting section in the previous process is also swept into the collection box 52, and the rewinding stops. At this time, the baffle 12 covers the vent 100 and stops rewinding. At this point, the baffle 12 and filter 11 of the shielding assembly 10 are cleaned with each power cycle of the air conditioner, achieving fully closed and fully automatic dust removal.

The shielding assembly 10 includes a filter 11 and a baffle 12 connected to each other. By moving the shielding assembly 10, the filter 11 and the baffle 12 can be selectively shielded at the vent 100. In this way, when the air conditioner is not working, the baffle 12 can shield the vent 100 to prevent external dust from falling into the interior of the air conditioner. In addition, the cleaning assembly 20 in the present application contacts the shielding assembly 10 so that when relative movement occurs between the cleaning assembly 20 and the shielding assembly 10, the dust on the shielding assembly 10 is cleaned by the cleaning assembly 20. In this way, the dust generated on the baffle 12 due to the air conditioner being stationary for a long time can be cleaned by the cleaning assembly 20, so that the baffle 12 is reeled synchronously along the distribution direction of the filter and the flexible baffle, thereby solving the problem that the dust at the baffle of the vent of the air conditioner in the prior art is difficult to clean, and realizing automatic cleaning of the baffle of the vent.
