Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a dust removal device and an indoor air conditioning unit having the same. Background Technology

[0002] Wall-mounted air conditioners typically have filters installed at the air inlet to prevent dust from falling into the evaporator. Traditional air conditioner filters require frequent cleaning and maintenance; moreover, before cleaning, the filters gradually become clogged, leading to reduced airflow, decreased overall performance, and increased power consumption. Even in some air conditioners with automatic filter cleaning systems, the filter remains exposed to the air when the air conditioner is not in use, meaning dust prevention is not thorough. Summary of the Invention

[0003] The main objective of this invention is to provide a dust removal device and an indoor air conditioning unit having the same, so as to solve the problem in the prior art that the filter screen of an air conditioner is exposed to the air and easily accumulates dust when it is not in use.

[0004] To achieve the above objectives, according to one aspect of the present invention, a dust removal device is provided, having an air inlet and a filter element. The dust removal device further includes: a first rotating part; a baffle, a first end of the baffle being connected to the first rotating part, and a second end of the baffle being connected to the filter element; wherein the first rotating part is rotatably disposed so that by rotating the first rotating part, the baffle is wound around the first rotating part so that at least a portion of the filter element is disposed opposite to the air inlet; or the first rotating part releases the baffle so that the baffle closes the air inlet.

[0005] Furthermore, the dust removal device also includes: a second rotating part, rotatably disposed, with at least a portion of the filter element wrapped around the second rotating part; a first guide channel, located between the first rotating part and the second rotating part; a second guide channel, located between the first rotating part and the second rotating part and on the side of the first guide channel away from the air inlet, the second guide channel being used to accommodate the filter element when the baffle closes the air inlet; and a cleaning element, used to clean the filter element entering the second guide channel.

[0006] Furthermore, the dust removal device also includes: a second rotating part, rotatably disposed, with at least a portion of the filter element wound around the second rotating part; a first guide channel located between the first rotating part and the second rotating part; and a third guide channel located between the first rotating part and the second rotating part and on the side of the first guide channel away from the air inlet, the third guide channel being used to accommodate the filter element when the baffle closes the air inlet.

[0007] Furthermore, the dust removal device also includes a third guide channel, located between the first rotating part and the second rotating part and between the first guide channel and the second guide channel, the third guide channel being used to accommodate the filter element when the baffle closes the air inlet.

[0008] Furthermore, the dust removal device also includes a shielding member having a first position for closing the first inlet of the second guide channel and a second position for closing the second inlet of the third guide channel, the shielding member switching between the first position and the second position.

[0009] Furthermore, the dust removal device also includes: a first partition plate forming a first guide channel with the air inlet; a second partition plate forming a third guide channel with the first partition plate; and a third partition plate located on the side of the second partition plate away from the first partition plate, forming a second guide channel with the second partition plate.

[0010] Furthermore, a connecting port is provided on the third partition plate, through which at least a portion of the cleaning component is positioned within the second guide channel.

[0011] Furthermore, the dust removal device also includes a first driving member, which is drivenly connected to the first rotating part.

[0012] Furthermore, the dust removal device also includes: a second rotating part, which is rotatably arranged, and the filter element is connected to the second rotating part.

[0013] Furthermore, the dust removal device also includes a second driving member, which is drivenly connected to the second rotating part.

[0014] Furthermore, the filter element includes a filter body and a transmission part, the transmission part having a first meshing tooth; the second rotating part includes a transmission gear, the transmission gear having a second meshing tooth, the transmission gear and the transmission part being connected by meshing through the first meshing tooth and the second meshing tooth.

[0015] According to another aspect of the present invention, an air conditioning indoor unit is provided, including the dust removal device described above.

[0016] The dust removal device of the present invention has an air inlet and a filter element, and further includes a first rotating part and a baffle. A first end of the baffle is connected to the first rotating part, and a second end of the baffle is connected to the filter element. The first rotating part is rotatably arranged. Since the first end of the baffle is connected to the first rotating part, rotating the first rotating part can drive the first end of the baffle to rotate, so that the baffle wraps around the first rotating part. Since the second end of the baffle is connected to the filter element, during the process of the baffle wrapping around the first rotating part, the second end of the baffle drives the filter element to move, so that at least a part of the filter element is positioned opposite to the air inlet, and the filter element achieves the dust removal effect. Alternatively, the first rotating part can be rotated in the opposite direction to release the baffle, so that the baffle closes the air inlet, the baffle blocks the air inlet, and the baffle pushes the filter element to move, so that the filter element is no longer positioned opposite to the air inlet, avoiding the problem that the filter element is exposed to the air and easily accumulates dust when the air conditioner is not in use.

[0027] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] This invention provides a dust removal device; please refer to [the relevant documentation]. Figures 1 to 6 The dust removal device has an air inlet 10 and a filter element 20. The dust removal device also includes: a first rotating part 30; a baffle 40, the first end of the baffle 40 being connected to the first rotating part 30 and the second end of the baffle 40 being connected to the filter element 20; wherein the first rotating part 30 is rotatably arranged so that by rotating the first rotating part 30, the baffle 40 is wound around the first rotating part 30 so that at least a portion of the filter element 20 is positioned opposite to the air inlet 10; or the first rotating part 30 is released to release the baffle 40 so that the baffle 40 closes the air inlet 10.

[0030] The dust removal device of the present invention has an air inlet 10 and a filter element 20, and further includes a first rotating part 30 and a baffle 40. A first end of the baffle 40 is connected to the first rotating part 30, and a second end of the baffle 40 is connected to the filter element 20. The first rotating part 30 is rotatably disposed. Since the first end of the baffle 40 is connected to the first rotating part 30, rotating the first rotating part 30 can drive the first end of the baffle 40 to rotate, causing the baffle 40 to wrap around the first rotating part 30. Since the second end of the baffle 40 is connected to the filter element 20, the baffle 40 wraps around the filter element 20. During the rotation of the first rotating part 30, the second end of the baffle 40 drives the filter element 20 to move, eventually causing at least a portion of the filter element 20 to be positioned opposite the air inlet 10, thus achieving the dust removal effect; or the first rotating part 30 can be rotated in the opposite direction to release the baffle 40, so that the baffle 40 closes the air inlet 10, blocking the air inlet 10, and the baffle 40 pushes the filter element 20 to move, so that the filter element 20 is no longer positioned opposite the air inlet 10, avoiding the problem of the filter element 20 being exposed to the air and easily accumulating dust when the air conditioner is not in use.

[0031] It should be noted that, as Figure 1 As shown, when the first rotating part 30 rotates clockwise, the baffle 40 is wrapped around the first rotating part 30; when the first rotating part 30 rotates counterclockwise, the baffle 40 is released.

[0032] Specifically, the baffle 40 is a flexible baffle that can be wrapped around the first rotating part 30 when it is not in use, thus avoiding the baffle 40 occupying space when not in use. Optionally, the baffle 40 is made of polyethylene terephthalate (PET).

[0033] Specifically, the filter element 20 is a filter screen. After the air passes through the air inlet 10, the air is filtered by the filter element 20, and the dust in the air is removed by the filter element 20.

[0034] Specifically, the filter element 20 is connected to the baffle 40 by ultrasonic welding or integral molding.

[0035] In this embodiment, the dust removal device further includes: a second rotating part 50, rotatably disposed, with at least a portion of the filter element 20 wound around the second rotating part 50; a first guide channel 60, located between the first rotating part 30 and the second rotating part 50; a second guide channel 70, located between the first rotating part 30 and the second rotating part 50 and on the side of the first guide channel 60 away from the air inlet 10, the second guide channel 70 being used to accommodate the filter element 20 when the baffle 40 closes the air inlet 10; and a cleaning member 80, used to clean the filter element 20 entering the second guide channel 70. It should be noted that the first rotating part 30 is connected to the baffle 40, and the second rotating part 50 is connected to the filter element 20. Both the first rotating part 30 and the second rotating part 50 are rotatably disposed so that they jointly drive the baffle 40 and the filter element 20 to move. This arrangement makes the movement of the baffle 40 and the filter element 20 more reliable.

[0036] In practice, when the filter element 20 needs to be cleaned, both the first rotating part 30 and the second rotating part 50 rotate, driving the filter element 20 into the second guide channel 70. The cleaning part 80 cleans the filter element 20 during the process of the filter element 20 entering the second guide channel 70 to remove the dust that has accumulated on the filter element 20 and cannot fall off, thus avoiding the problem of excessive dust on the filter element 20 affecting the air conditioning performance.

[0037] In specific implementation, such as Figure 3 and Figure 4 As shown, when the filter element 20 is working, the filter element 20 is disposed in the first guide channel 60, at least a portion of the filter element 20 is disposed opposite to the air inlet 10, the first end of the filter element 20 is connected to the second end of the baffle 40, and at least a portion of the second end of the filter element 20 is wrapped around the second rotating part 50; when the filter element 20 needs to be cleaned, the second rotating part 50 drives the second end of the filter element 20 to rotate around the second rotating part 50 until the second end of the filter element 20 is disengaged from the second rotating part 50, and the portion between the second end and the first end of the filter element 20 continues to rotate around the second rotating part 50 until the first end of the filter element 20 is wrapped around the second rotating part 50, and the entire filter element 20 enters the second guide channel 70. During this process, the surface of the filter element 20 is cleaned by the cleaning part 80, removing dust.

[0038] Specifically, such as Figure 2As shown, the dust removal device also includes a dust collection box 160, which is located below the cleaning component 80. During the cleaning process of the cleaning component 80, dust will fall off and fall into the dust collection box 160, thus preventing dust from entering the air conditioner after cleaning and affecting the performance of the air conditioner.

[0039] In this embodiment, as Figure 2 As shown, the dust removal device also includes a third guide channel 90, located between the first rotating part 30 and the second rotating part 50, and between the first guide channel 60 and the second guide channel 70. The third guide channel 90 is used to accommodate the filter element 20 when the baffle 40 closes the air inlet 10. In specific implementation, when the filter element 20 does not need to be dusted and the air conditioner is not in operation, the second rotating part 50 drives the filter element 20 into the third guide channel 90. During the process of entering the third guide channel 90, the filter element 20 does not need to be cleaned by the cleaning element 80, avoiding the need for the filter element 20 to pass through the cleaning element 80 every time it is recycled while in a clean state. This ensures that the cleaning element 80 will not be easily damaged and increases its service life. The position setting of the third guide channel 90 ensures that the filter element 20 in the first guide channel 60 is in contact with the air inlet 10 to achieve automatic dust removal of the air, and also ensures that it does not come into contact with the cleaning element 80 during the process of entering the third guide channel 90.

[0040] Specifically, the cleaning component 80 is a brush.

[0041] It should be noted that the dust removal device in this embodiment includes a second guide channel 70 and / or a third guide channel 90. When the dust removal device only includes the third guide channel 90, the third guide channel 90 is located between the first rotating part 30 and the second rotating part 50 and on the side of the first guide channel 60 away from the air inlet 10. The third guide channel 90 is used to accommodate the filter element 20 when the baffle 40 closes the air inlet 10. When the air conditioner is not in operation, the second rotating part 50 drives the filter element 20 into the third guide channel 90, thus solving the problem of storing the filter element 20 while the baffle closes the air inlet.

[0042] In this embodiment, as Figure 2 As shown, the dust removal device also includes a shield 100, having a first position for closing the first inlet 71 of the second guide channel 70 and a second position for closing the second inlet 91 of the third guide channel 90, the shield 100 switching between the first position and the second position.

[0043] In practice, the shielding component 100 can block the first inlet 71 or the second inlet 91, so that the filter element 20 can determine whether to enter the second guide channel 70 or the third guide channel 90 based on the state of its accumulated dust. When it needs to enter the second guide channel 70, the second inlet 91 is closed, and when it needs to enter the third guide channel 90, the first inlet 71 is closed, thus preventing the filter element 20 from entering the wrong channel.

[0044] Specifically, a sensor is installed on the filter element 20. The sensor detects the amount of dust accumulated on the filter element 20. If the amount of dust is greater than or equal to the user-set value, the filter element 20 enters the second guide channel 70 for dust removal. If the amount of dust is less than the user-set value, the filter element 20 enters the third guide channel 90.

[0045] In this embodiment, as Figure 2 As shown, the dust removal device further includes: a first partition plate 110, which forms a first guide channel 60 with the air inlet 10; a second partition plate 120, which forms a third guide channel 90 with the first partition plate 110; and a third partition plate 130, located on the side of the second partition plate 120 away from the first partition plate 110, which forms a second guide channel 70 with the second partition plate 120.

[0046] In practice, the arrangement of the first partition plate 110, the second partition plate 120 and the third partition plate 130 forms the first guide channel 60, the third guide channel 90 and the second guide channel 70, so that the filter element 20 can be in different channels in different states.

[0047] In this embodiment, a communication port is provided on the third partition plate 130, and at least a portion of the cleaning member 80 is disposed in the second guide channel 70 through the communication port.

[0048] In practice, since at least part of the cleaning component 80 is set in the second guide channel 70 through the connecting port, the filter component 20 is cleaned by the cleaning component 80 during the process of entering the second guide channel 70, thus realizing the dust cleaning process.

[0049] In this embodiment, the dust removal device further includes a first driving member 140, which is drivenly connected to the first rotating part 30.

[0050] In practice, the first driving component 140 drives the first rotating part 30 to rotate, thereby moving the baffle 40 and the filter 20 to achieve the mode switching of the air conditioner.

[0051] Optionally, the first driving component 140 is a motor.

[0052] In this embodiment, the dust removal device further includes a second rotating part 50, which is rotatably disposed, and the filter element 20 is connected to the second rotating part 50.

[0053] In practice, the second rotating part 50 drives the filter element 20 to move, so that the filter element 20 enters different first guide channels 60, third guide channels 90 and second guide channels 70, so that the filter element 20 can enter the working, dust removal and normal modes.

[0054] In this embodiment, the dust removal device further includes a second driving member 150, which is drivenly connected to the second rotating part 50.

[0055] In practice, the second driving member 150 drives the second rotating part 50 to rotate, thereby moving the filter element 20.

[0056] Optionally, the second drive element 150 is a motor.

[0057] In this embodiment, the filter element 20 includes a filter body 21 and a transmission part 22, the transmission part 22 having a first meshing tooth; the second rotating part 50 includes a transmission gear 51, the transmission gear 51 having a second meshing tooth, the transmission gear 51 and the transmission part 22 being connected by meshing through the first meshing tooth and the second meshing tooth.

[0058] In specific implementation, the filter body 21 is a filter screen, which is used to filter the air entering through the air inlet; through the transmission cooperation between the transmission part 22 of the filter element 20 and the transmission gear 51, the second rotating part 50 can transport the filter element 20 into the first guide channel 60, the third guide channel 90 and the second guide channel 70.

[0059] This invention also provides an indoor air conditioning unit, please refer to... Figure 6 This includes the dust removal device described in the above embodiments.

[0060] When this application is specifically implemented:

[0061] Before the air conditioner is turned off, the filter is in working mode, such as... Figure 3 As shown, the sensor on filter element 20 detects filter element 20 and records its cleanliness level. The next time the device is turned on, if the previously recorded dust accumulation on filter element 20 is greater than or equal to the user-defined value X (the default value is used if no value is set), the dust removal mode will automatically activate. Figure 4As shown, when the first rotating part 30 completely rolls up the baffle 40, the blocking part 100 will rotate to the position of the second inlet 91. After the machine is turned off, the filter element 20 will enter the second guide channel 70 from the first guide channel 60, passing through the cleaning part 80 for a cleaning. The cleaned dust will fall into the dust collection box 160. When the machine is turned on again, the filter element 20 will return from the second guide channel 70 to the first guide channel 60, and the filter element 20 will pass through the cleaning part 80 again for a cleaning. Until the machine is turned off, if the amount of dust accumulated on the filter element 20 recorded last time is less than the user-set value X, the dust removal mode will be canceled and the normal mode will be turned on. Figure 5 As shown, when the first rotating part 30 rolls up the baffle 40 completely, the shield 100 will rotate to the position of the first inlet 71. After the machine is turned off, the filter 20 will return from the first guide channel 60 through the shield 100 to the third guide channel 90, without passing through the cleaning part 80, ensuring that the filter 20 is in a clean state and does not damage the cleaning part 80, thus increasing the service life of the cleaning part 80.

[0062] This application solves the following technical problems:

[0063] This solution addresses the problem of dust accumulation in the air-exposed filter element 20 when the air conditioner is not in use; it also solves the problem of difficulty in manually cleaning the filter element 20; and it addresses the problem of easy damage to the cleaning element 80.

[0064] This application has the following beneficial effects:

[0065] When the air conditioner is not in use, the fully enclosed air inlet 10, which combines the filter element 20 with the baffle 40, can effectively prevent dust. The addition of the cleaning element 80 enables automatic dust removal. Based on the cleanliness of the filter element 20, the system automatically determines whether the filter element 20 is running in different guide channels, thereby achieving automatic dust removal while reducing wear on the cleaning element 80 and extending its service life.

[0066] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0067] The dust removal device of the present invention has an air inlet 10 and a filter element 20, and further includes a first rotating part 30 and a baffle 40. A first end of the baffle 40 is connected to the first rotating part 30, and a second end of the baffle 40 is connected to the filter element 20. The first rotating part 30 is rotatably disposed. Since the first end of the baffle 40 is connected to the first rotating part 30, rotating the first rotating part 30 can drive the first end of the baffle 40 to rotate, causing the baffle 40 to wrap around the first rotating part 30. Since the second end of the baffle 40 is connected to the filter element 20, the baffle 40 wraps around the filter element 20. During the rotation of the first rotating part 30, the second end of the baffle 40 drives the filter element 20 to move, eventually causing at least a portion of the filter element 20 to be positioned opposite the air inlet 10, thus achieving the dust removal effect; or the first rotating part 30 can be rotated in the opposite direction to release the baffle 40, so that the baffle 40 closes the air inlet 10, blocking the air inlet 10, and the baffle 40 pushes the filter element 20 to move, so that the filter element 20 is no longer positioned opposite the air inlet 10, avoiding the problem of the filter element 20 being exposed to the air and easily accumulating dust when the air conditioner is not in use.
