Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to a fan and an air conditioner. Background Technology

[0002] Currently, most air conditioner filters on the market rely on manual cleaning, but most consumers often forget to clean them, resulting in a large accumulation of dust on the air conditioner filters. This not only reduces the air intake of the air conditioner, leading to increased power consumption, but also causes secondary pollution of indoor air quality.

[0003] Some existing air conditioners are equipped with filter cleaning devices to automatically clean the filter, but the constant contact between the cleaning device and the filter can lead to reduced filter life and obstructed airflow. Summary of the Invention

[0004] The problem solved by this invention is that the cleaning device of existing air conditioners is always in contact with the filter, which reduces the lifespan of the filter and obstructs airflow.

[0005] To address the aforementioned problems, this invention provides a fan and an air conditioner that can solve the problems of reduced filter life and obstructed airflow caused by the cleaning device constantly being in contact with the filter.

[0006] In a first aspect, the present invention provides a fan, including a housing, a filter, and a cleaning component. The housing is provided with an air inlet channel, the filter is disposed in the air inlet channel, and the cleaning component is movably installed on the housing. The cleaning component has a working state in contact with the filter and a non-working state separated from the filter. In the working state, the cleaning component can clean the dust from the filter.

[0007] This application movably mounts the cleaning component onto the housing, allowing it to operate in contact with the filter and in a non-operating state. In its operating state, the cleaning component cleans dust from the filter; in its non-operating state, it separates from the filter, preventing prolonged contact and thus reducing wear on the filter and extending its lifespan. Furthermore, separating the cleaning component from the filter increases the filter's air intake area, thereby improving the fan's air intake efficiency.

[0008] In an optional embodiment, the cleaning component includes a cleaning brush and an actuator, both of which are disposed in the housing, and the cleaning brush is movable relative to the housing. The actuator is used to drive the cleaning brush to move so that the cleaning brush contacts or separates from the filter.

[0009] This embodiment incorporates an actuator and a cleaning brush, allowing the cleaning brush to move relative to the housing. The actuator enables convenient control and drive of the cleaning brush to contact and separate from the filter, making it more convenient to use.

[0010] In an optional embodiment, the cleaning brush is movably disposed within the housing, and the actuator can drive the cleaning brush to move towards or away from the filter. Movable disposal of the cleaning brush within the housing, coupled with the ability of the actuator to easily drive the brush towards or away from the filter, achieves contact or separation between the cleaning brush and the filter, resulting in a simpler structure and more convenient operation.

[0011] In an optional embodiment, the actuator includes a drive member and a guide member. The drive member is mounted on the housing, and the guide member is throttle-connected to the drive member. The drive member can drive the guide member to move in a first movement direction and a second movement direction, wherein the first movement direction and the second movement direction are opposite. When the guide member moves in the first movement direction, it can push the cleaning brush to move closer to the filter screen, so that the cleaning brush contacts the filter screen. When the guide member moves in the second movement direction, the cleaning brush can move away from the filter screen, so that the cleaning brush separates from the filter screen.

[0012] This application uses a driving component and a guide component to drive the guide component to move in the first and second motion directions, thereby facilitating the movement of the filter screen. The structure is simple and the use is more convenient.

[0013] In an optional embodiment, the cleaning assembly further includes a drive motor mounted on the housing, and the cleaning brush movably mounted on the output shaft of the drive motor. The drive motor can drive the cleaning brush to rotate, and when the guide rotates in the first direction of movement, the guide can push the cleaning brush to move along the output shaft of the drive motor.

[0014] This application allows the cleaning brush to be easily pushed and brought into contact with the filter screen by the rotation of the guide component. By incorporating a drive motor, the filter screen is rotated when the cleaning brush contacts it, facilitating easy and thorough cleaning of the filter screen.

[0015] In an optional embodiment, the cleaning assembly further includes an elastic element sleeved on the output shaft of the drive motor and disposed on the side of the cleaning brush near the filter screen. When the guide rotates in the second direction of movement, the elastic element can push the cleaning brush to move away from the filter screen.

[0016] By incorporating an elastic element, this application avoids mechanical connection between the guide element and the cleaning brush. When the guide element rotates in the first direction, it can easily push the cleaning brush to contact the filter screen. When the guide element rotates in the second direction, the elastic element can easily push the cleaning brush to move away from the filter screen, thus separating the cleaning brush from the filter screen, making the structure simpler.

[0017] In an optional embodiment, the fan further includes fan blades mounted on the output shaft of the drive motor, which drives the fan blades to rotate. This application achieves lower costs by rotatably mounting the fan blades on the output shaft of the drive motor, allowing the rotation of the fan blades and the rotation of the filter to share a single drive motor.

[0018] In an optional embodiment, the cleaning brush is rotatably disposed on the housing, and the actuator is throttle-connected to the cleaning brush. The actuator can drive the cleaning brush to rotate so that the brush head of the cleaning brush faces toward or away from the filter screen. When the brush head of the cleaning brush faces the filter screen, the brush head of the cleaning brush is in contact with the filter screen. When the brush head of the cleaning brush is away from the filter screen, the brush head of the cleaning brush is separated from the filter screen.

[0019] This application rotatably mounts a cleaning brush within a housing and connects an actuator to the cleaning brush via a transmission mechanism. The actuator drives the cleaning brush to rotate, causing the brush head to face the filter screen and make contact with it. Simultaneously, the actuator can also drive the cleaning brush to rotate, moving the brush head away from the filter screen and separating it from it.

[0020] In an optional embodiment, the actuator includes a motor, the filter screen is rotatably mounted in the air inlet channel, the motor is mounted in the housing, and the cleaning brush is mounted on the output shaft of the motor. Rotating the filter screen in the air inlet channel allows the motor to be fixedly mounted in the housing; when the brush head rotates to contact the filter screen, the filter screen rotates, thus achieving complete cleaning of the filter screen.

[0021] In an optional embodiment, the fan further includes a tension regulator mounted on the side of the filter screen away from the cleaning brush, and the tension regulator corresponds to the cleaning brush.

[0022] This application improves the cleaning effect of the filter by setting a tension regulator on the side of the filter screen away from the cleaning brush. The tension regulator supports the filter screen, allowing the cleaning brush to make better contact with the filter screen.

[0023] Secondly, the present invention provides an air conditioner including the fan described in any of the foregoing embodiments.

[0024] The air conditioner provided in this application has a cleaning component movably mounted on the housing, allowing the cleaning component to have an operating state in contact with the filter and a non-operating state separated from the filter. In the operating state, the cleaning component cleans the dust from the filter; in the non-operating state, it separates from the filter, avoiding prolonged contact between the cleaning component and the filter, thus reducing wear on the filter and extending its service life. Secondly, when the cleaning component is separated from the filter, the air intake area of ​​the filter can be increased, thereby improving the air intake efficiency of the fan.

Detailed Implementation

[0034] Some existing air conditioners also have filter cleaning devices to automatically clean the filter 130, but the fact that the cleaning device is always in contact with the filter 130 can lead to a reduction in the lifespan of the filter 130 and obstruction of airflow.

[0035] To solve the above problems, the present invention provides a fan 100 and an air conditioner, which can solve the problems of reduced lifespan of filter 130 and obstructed airflow caused by the cleaning device always being in contact with filter 130.

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Example 1

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 The present invention provides an air conditioner, including an indoor unit and an outdoor unit, which are connected by pipes to deliver cold or hot air into a building or structure to regulate the indoor temperature.

[0039] In this embodiment, the indoor unit includes an evaporator and a fan 100. The fan 100 is used to supply air into the building or structure, and the heat exchanger is used to exchange heat with the air to achieve cooling and heating of the air.

[0040] In this embodiment, the fan 100 includes a housing 110, a filter 130, and a cleaning assembly 150. The housing 110 is provided with an air inlet channel 111, the filter 130 is disposed in the air inlet channel 111, and the cleaning assembly 150 is movably installed on the housing 110. The cleaning assembly 150 has a working state in contact with the filter 130 and a non-working state separated from the filter 130. In the working state, the cleaning assembly 150 can clean the dust from the filter 130.

[0041] In this embodiment, the cleaning component 150 is movably mounted on the housing 110, allowing the cleaning component 150 to have a working state in contact with the filter screen 130 and a non-working state separated from the filter screen 130. In the working state, the cleaning component 150 cleans the dust from the filter screen 130, while in the non-working state, it is separated from the filter screen 130. This avoids prolonged contact between the cleaning component 150 and the filter screen 130, thereby reducing wear on the filter screen 130 and extending its service life. Furthermore, when the cleaning component 150 is separated from the filter screen 130, the air inlet area of ​​the filter screen 130 can be increased, thus improving the air intake efficiency of the fan 100.

[0042] In this embodiment, the cleaning component 150 includes a cleaning brush 151 and an actuator 153. Both the cleaning brush 151 and the actuator 153 are disposed on the housing 110, and the cleaning brush 151 is movable relative to the housing 110. The actuator 153 is used to drive the cleaning brush 151 to move so that the cleaning brush 151 contacts or separates from the filter screen 130.

[0043] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, by setting an actuator 153 and a cleaning brush 151, and making the cleaning brush 151 movable relative to the housing 110, the actuator 153 can conveniently control and drive the cleaning brush 151 to contact and separate from the filter screen 130, making it more convenient to use.

[0044] In this embodiment, the cleaning brush 151 is movably disposed on the housing 110. The actuator 153 can drive the cleaning brush 151 to move towards or away from the filter screen 130. By movably disposing the cleaning brush 151 on the housing 110, and using the actuator 153 to easily drive the cleaning brush 151 towards or away from the filter screen 130, the cleaning brush 151 can be brought into contact with or separated from the filter screen 130, resulting in a simpler structure and more convenient operation.

[0045] It is worth noting that the cleaning brush 151 can be movably disposed in the housing 110. This can mean that the entire cleaning brush 151 can move relative to the housing 110, or that a part of the cleaning brush 151 can move relative to the housing 110. For example, the brush head of the cleaning brush 151 may deform under external pressure and move to contact the filter screen 130.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the actuator 153 includes a drive member (not shown) and a guide member 157. The drive member is mounted on the housing 110, and the guide member 157 is driveably connected to the drive member. The drive member can drive the guide member 157 to move in a first movement direction and a second movement direction, which are opposite to each other. When the guide member 157 moves in the first movement direction, it can push the cleaning brush 151 to move closer to the filter screen 130, so that the cleaning brush 151 contacts the filter screen 130. When the guide member 157 moves in the second movement direction, the cleaning brush 151 can move away from the filter screen 130, so that the cleaning brush 151 separates from the filter screen 130.

[0047] This embodiment uses a driving component and a guide component 157. The driving component drives the guide component 157 to move in the first and second movement directions, thereby facilitating the movement of the filter screen 130. The structure is simple and the use is more convenient.

[0048] Of course, it is understood that in other embodiments of this application, the drive component can also be installed in other locations on the air conditioner, such as the middle frame, rear panel frame, or other structural components. The requirement is that the drive component can drive the guide 157 to move in the first direction, pushing the cleaning brush 151 towards the filter 130 to make the filter 130 contact the cleaning brush 151, and that the cleaning brush 151 can separate from the guide 157 when the drive component drives the guide 157 to move in the second direction.

[0049] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the cleaning assembly 150 further includes a drive motor 159. The drive component is a cloth-feeding motor 165. The drive component is fixedly installed in the housing 110, and the guide component 157 is connected to the drive component in a transmission manner, and the guide component 157 can rotate relative to the housing 110. The drive motor 159 is fixedly installed in the housing 110. The cleaning brush 151 is movably installed on the output shaft of the drive motor 159, and the drive motor 159 can drive the cleaning brush 151 to rotate. That is, the cleaning brush 151 can only move along the output shaft of the drive motor 159 and cannot rotate along the output shaft of the drive motor 159. The rotation of the cleaning brush 151 can only be driven by the drive motor 159. When the guide component 157 rotates in the first direction of movement, the guide component 157 can push the cleaning brush 151 to move along the output shaft of the drive motor 159 so that the cleaning brush 151 contacts the filter screen 130.

[0050] The rotation of the guide member 157 facilitates the pushing of the cleaning brush 151, bringing it into contact with the filter screen 130. By providing a drive motor 159, the filter screen 130 is rotated when the cleaning brush 151 contacts it, allowing for convenient and thorough cleaning.

[0051] It is understood that in this embodiment, one of the first and second movement directions is clockwise rotation and the other is counterclockwise rotation. For example, when the guide 157 rotates clockwise, the guide 157 can push the cleaning brush 151 towards the filter 130. Then, when the guide 157 rotates counterclockwise, the cleaning brush 151 can move away from the filter 130.

[0052] Of course, it is also understood that in some other embodiments of this application, the first and second movement directions can also be two directions of linear motion. That is, the first movement direction is when the guide member 157 moves towards the filter screen 130, and the second movement direction is when the guide member 157 moves away from the filter screen 130. When the first and second movement directions are two opposite directions on a straight line, the driving member can be a telescopic device, such as an electric actuator. The driving member can also be a device with linear reciprocating motion function composed of a motor 165 as the motion source. The driving member can also be an electromagnet or other device made using electromagnetic principles.

[0053] In other embodiments of this application, the cleaning brush 151 may be movably mounted on the housing 110 and rotated by the filter screen 130 to clean the filter screen 130. For example, a mounting shaft is fixedly provided on the housing 110, and a drive component is movably mounted on the mounting shaft. The drive motor 159 drives the filter screen 130 to rotate. When the filter screen 130 needs to be cleaned, the guide component 157 pushes the cleaning brush 151 to move along the mounting shaft so that the cleaning brush 151 contacts the filter screen 130. Then, the drive motor 159 is turned on to drive the filter screen 130 to rotate, thereby achieving complete cleaning of the filter screen 130.

[0054] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the cleaning assembly 150 further includes an elastic element 161. The elastic element 161 is sleeved on the output shaft of the drive motor 159 and is disposed on the side of the cleaning brush 151 near the filter screen 130. One side of the elastic element 161 abuts against the filter screen 130, and the other side abuts against the limiting platform 163 disposed on the output shaft of the drive motor 159. When the guide member 157 rotates in the second movement direction, the guide member 157 cancels the pushing force on the cleaning brush 151. At this time, under the action of the restoring force, the elastic element 161 can push the cleaning brush 151 to move away from the filter screen 130, so that the cleaning brush 151 separates from the filter screen 130.

[0055] By providing the elastic element 161, this application can avoid mechanical connection between the guide element 157 and the cleaning brush 151. When the guide element 157 rotates in the first direction, it can easily push the cleaning brush 151 to contact the filter screen 130. When the guide element 157 rotates in the second direction, the elastic element 161 can easily push the cleaning brush 151 to move away from the filter screen 130, thereby separating the cleaning brush 151 from the filter screen 130, making the structure simpler.

[0056] In this embodiment, the elastic element 161 is a spring. Of course, in other embodiments of this application, the elastic element 161 may also be a sheet or other elastic material.

[0057] Secondly, in some other embodiments of this application, the guide member 157 can also be movably connected to the cleaning brush 151. When the guide member 157 rotates in the second direction of movement, the guide member 157 can pull the cleaning brush 151 to separate from the filter screen 130. For example, the drive member is fixedly connected to the output shaft of the drive motor 159, one end of the guide member 157 is connected to the drive member for transmission, and the other end is movably connected to the cleaning brush 151.

[0058] In this embodiment, the guide 157 is cam-shaped, and rotating the guide 157 at different angles can move the filter 130 by different distances. In this embodiment, the guide 157 has a triangular structure. In other embodiments of this application, the guide 157 may also have an elliptical structure.

[0059] In this embodiment, the fan 100 also includes fan blades (not shown), which are mounted on the output shaft of the drive motor 159. The drive motor 159 can drive the fan blades to rotate. That is, the rotation of the fan blades and the rotation of the cleaning brush 151 share a single drive motor 159. This application achieves lower costs by mounting the fan blades of the fan 100 on the output shaft of the drive motor 159, so that the rotation of the fan blades and the rotation of the cleaning brush 151 share a single drive motor 159.

[0060] Of course, in some other embodiments of this application, the rotation of the cleaning brush 151 and the rotation of the fan blades can also be driven by two independent drive motors 159.

[0061] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the cleaning component 150 also includes a dust collection box 170, which is installed on the housing 110 and is used to collect dust swept by the cleaning brush 151.

[0062] In this embodiment, the fan 100 is a Sirocco fan 100. Air inlet channels 111 are provided on both opposite sides of the housing 110. The number of filters 130 and cleaning components each includes two, with two air inlet channels 111 corresponding to each of the two filters 130 and the two cleaning components.

[0063] In other embodiments of this application, the fan 100 may also be other types of axial flow fan 100 or radial flow fan 100.

[0064] Example 2

[0065] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7This embodiment is basically the same as Embodiment 1, except that the cleaning brush 151 is rotatably mounted on the housing 110, and the actuator 153 is connected to the cleaning brush 151 in a transmission manner. The actuator 153 can drive the cleaning brush 151 to rotate, so that the brush head of the cleaning brush 151 faces or moves away from the filter screen 130. When the brush head of the cleaning brush 151 faces the filter screen 130, the brush head of the cleaning brush 151 is in contact with the filter screen 130. When the brush head of the cleaning brush 151 moves away from the filter screen 130, the brush head of the cleaning brush 151 separates from the filter screen 130.

[0066] This application rotatably mounts a cleaning brush 151 onto a housing 110 and connects an actuator 153 to the cleaning brush 151. The actuator 153 drives the cleaning brush 151 to rotate, causing the brush head of the cleaning brush 151 to face the filter screen 130, thus bringing the cleaning brush 151 into contact with the filter screen 130. Simultaneously, the actuator 153 can also drive the cleaning brush 151 to rotate, causing the brush head of the cleaning brush 151 to move away from the filter screen 130, thereby separating it from the filter screen 130.

[0067] In this embodiment, the actuator 153 includes a motor 165. A filter screen 130 is rotatably mounted in the air inlet channel 111. The motor 165 is mounted in the housing 110, and a cleaning brush 151 is mounted on the output shaft of the motor 165. By rotatably mounting the filter screen 130 in the air inlet channel 111, the motor 165 can be fixedly mounted in the housing 110. When the brush head rotates to contact the filter screen 130, the filter screen 130 rotates, thus achieving complete cleaning of the filter screen 130.

[0068] In this embodiment, the filter 130 and the fan blades share a drive motor 159, and the drive motor 159 can drive the fan blades and the filter 130 to rotate simultaneously.

[0069] Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 In this embodiment, the fan 100 also includes a tension regulator 167, which is installed on the side of the filter 130 away from the cleaning brush 151 and is fixedly connected to the housing 110. The tension regulator 167 corresponds to the cleaning brush 151.

[0070] This application provides a tension regulator 167, which is positioned on the side of the filter screen 130 away from the cleaning brush 151. This allows the tension regulator 167 to support the filter screen 130 during cleaning, enabling the cleaning brush 151 to make better contact with the filter screen 130 and thus improving the cleaning effect of the filter screen 130.

[0071] Specifically, the two ends of the tension regulator 167 are fixedly connected to the housing 110, and the middle of the tension regulator 167 is provided with a through hole 169 for the output shaft of the drive motor 159 to pass through. However, there is a gap between the output shaft of the drive motor 159 and the through hole 169, so that the output shaft of the drive motor 159 will not affect the tension regulator 167 when it rotates.

[0072] In summary, the working principle and beneficial effects of the fan 100 and air conditioner provided in the embodiments of the present invention include:

[0073] This application movably mounts the cleaning component 150 onto the housing 110, allowing the cleaning component 150 to have both a working state in contact with the filter screen 130 and a non-working state separated from the filter screen 130. In the working state, the cleaning component 150 cleans the dust from the filter screen 130; in the non-working state, it separates from the filter screen 130, preventing prolonged contact between the cleaning component 150 and the filter screen 130, thereby reducing wear on the filter screen 130 and extending its service life. Furthermore, when the cleaning component 150 is separated from the filter screen 130, the air inlet area of ​​the filter screen 130 can be increased, thus improving the air intake efficiency of the fan 100.

[0074] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
