Description

Technical Field

[0001] This application relates to the field of air handling technology, and in particular to a self-cleaning filter device for a dehumidifier unit. Background Technology

[0002] Currently, air humidity control is crucial in daily life and numerous industrial production scenarios. Suitable humidity not only enhances living comfort but also ensures product quality and equipment operation in industrial production. For example, in electronics manufacturing workshops, excessive humidity can damage electronic components due to moisture; in the field of document storage, a damp environment accelerates mold growth on paper, film, and other materials. Therefore, dehumidifiers, as devices that effectively regulate air humidity, are widely used in various fields and have become a key tool for ensuring suitable environmental humidity.

[0003] In related technologies, a dehumidifier typically consists of a shell forming an overall frame, with a dedicated air inlet on the front side of the shell, providing a channel for air to enter. Simultaneously, a humidity monitoring device is cleverly installed inside the shell. This device can sense the humidity of the surrounding air in real time and feed the data back to the dehumidifier's control system. This allows for precise adjustment of the dehumidifier's operating status based on the actual humidity conditions, achieving a relatively intelligent humidity control function and meeting the humidity regulation needs of different scenarios.

[0004] In the aforementioned technologies, since dust and other impurities inevitably exist in the air, when the dehumidifier is running, these dust particles enter and adhere to the air inlet and the inside of the dehumidifier as air enters through the air inlet. As the usage time continues to extend, the dust adhering to the air inlet will gradually increase and accumulate. This not only affects the normal air circulation and reduces the efficiency of air entering the dehumidifier, but more seriously, it will cause the dehumidification components inside the dehumidifier to fail to perform their functions fully, thus significantly reducing the overall dehumidification function of the dehumidifier, affecting its performance and lifespan, and there is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a self-cleaning filter device for dehumidifier units, which solves the problem in the above-mentioned related technologies that dust enters the dehumidifier with the air and accumulates at the air inlet and inside the dehumidifier, causing a significant decline in the overall dehumidification function of the dehumidifier over a long period of time.

[0006] The self-cleaning filter device for a dehumidifier unit provided in this application adopts the following technical solution: A self-cleaning filtration device for a dehumidifier unit includes a dehumidifier housing. An air inlet is located on the front side of the dehumidifier housing, and an air outlet is located on the bottom surface. A guide plate is fixed inside the dehumidifier housing. A first chamber is located on the left side of the guide plate, and a second chamber is located on the right side. A dust filter is provided on the front side of the dehumidifier housing near the air inlet and close to the first chamber. A support member is fixed on the inner wall of the air inlet to support the dust filter. The dust filter is used to adsorb dust and other impurities in the air.

[0007] By adopting the above technical solution, a dust filter is installed at the air inlet on the front side of the dehumidifier casing near the first chamber, and is supported by a support component on the inner wall of the air inlet. When air enters from the air inlet, the dust filter can efficiently adsorb dust and other impurities in the air by virtue of its own characteristics, preventing dust from entering the dehumidifier with the air and accumulating at the air inlet and inside. In this way, normal air circulation in the dehumidifier is ensured, the efficiency of air entering the dehumidifier is improved, and the dehumidification components inside the dehumidifier can play a full role, maintaining the overall dehumidification function of the dehumidifier, extending the service life of the dehumidifier, and improving its effect and reliability in regulating air humidity in different scenarios.

[0008] Optionally, a flow collector shroud and a second drive component for controlling the wind force entering the flow collector shroud are fixed on the inner wall of the first chamber, and a clearance notch is provided on the guide plate for one end of the flow collector shroud to be inserted.

[0009] By adopting the above technical solution, the air collection hood is fixed to the inner wall of the first chamber. Its special design can effectively gather the gas entering from the air inlet, making the airflow more concentrated and orderly. The second driving component can control the wind force entering the air collection hood and flexibly adjust the airflow intensity according to the actual operating needs of the dehumidifier. This ensures that the amount of air entering the dehumidifier meets the dehumidification requirements and avoids the dehumidification effect being affected by excessive or insufficient wind force.

[0010] Optionally, a dust collection box located above the second drive unit can be detachably installed on the inner wall of the first chamber. The dust collection box is used to collect dust that falls off when the cleaning brush cleans the dust filter.

[0011] By adopting the above technical solution, when the cleaning brush cleans the dust filter, the dust will fall off naturally. The dust collection box can effectively collect this dust and prevent it from falling back into other parts of the dehumidifier, thus avoiding secondary pollution. Moreover, the dust collection box adopts a detachable design, which greatly facilitates the subsequent cleaning of dust. Users only need to remove the dust collection box to easily empty the dust inside, making the operation simple and quick.

[0012] Optionally, the support member includes an upper support roller rotatably connected to the front side of the dehumidifier housing in a horizontal direction, and a lower support roller arranged parallel to the upper support roller in a vertical direction; the dust filter is sleeved on the outer circumferential surface of the upper and lower support rollers, and the dehumidifier housing is provided with a rotating member that drives the upper and lower support rollers to rotate along their own axis; the upper and lower support rollers can drive the dust filter to operate under the drive of the rotating member.

[0013] By adopting the above technical solution, this structure realizes dynamic filtration of the dust filter. Compared with the static filter, the operating filter allows different parts to come into contact with the air in sequence, avoiding the blockage caused by a certain area being subjected to high concentration of dust for a long time, and effectively extending the service life of the filter.

[0014] Optionally, the rotating component includes a drive wheel rotatably connected to both ends of the upper support roller, a drive impeller rotatably connected to the inner wall of the second chamber, and a belt connecting the drive wheel and the drive impeller; when the wind force drives the drive impeller to rotate, the drive impeller can drive the belt to move, and the two drive wheels can rotate along their own axis under the drive of the belt, and the upper support roller and the lower support roller can drive the dust filter to operate under the drive of the two drive wheels.

[0015] By adopting the above technical solution, when air flow generates wind, the drive impeller rotates under the action of wind. Through belt transmission, it drives the drive wheels connected to both ends of the upper support roller to rotate, thereby making the upper and lower support rollers rotate synchronously, driving the dust filter to circulate. This design does not require additional power consumption, truly achieving self-cleaning without any power consumption, and reducing operating costs and energy consumption.

[0016] Optionally, a cleaning brush is provided on the front side of the dehumidifier housing away from the lower support roller. The cleaning brush can clean the dust attached to the dust filter when the dust filter is in operation.

[0017] By adopting the above technical solution, when the dust filter is continuously rotated by the rotating parts, the cleaning brush will fully contact the surface of the filter and automatically brush and clean the dust attached to it. This design realizes real-time online cleaning of the filter without frequent manual intervention, which greatly improves the cleaning efficiency and ensures that the filter always maintains good filtration performance. At the same time, timely removal of dust can prevent the filter from clogging, ensure smooth air circulation, and thus maintain the stable dehumidification effect of the dehumidifier.

[0018] Optionally, the top surface of the cleaning brush is provided with an elastic element, which enables the cleaning brush to have a rotational force to rotate towards the dust filter.

[0019] By adopting the above technical solution, this ingenious design ensures that the cleaning brush and the dust filter always maintain a close and stable contact. No matter if the dust filter undergoes slight deformation due to long-term use or fluctuates in position under different operating conditions, the elastic element can make the cleaning brush self-adjust and continuously adhere to the filter surface.

[0020] Optionally, the elastic element is a torsion spring sleeved on the outer circumferential surface of the cleaning brush, and the two ends of the torsion spring are respectively fixedly connected to the inner wall of the dehumidifier housing.

[0021] By adopting the above technical solution, during the operation of the cleaning brush, when the dust filter exerts forces on it in different directions, the torsion spring can continuously provide a force for the cleaning brush to rotate towards the dust filter, ensuring that the cleaning brush always fits tightly against the filter. This fixing method is simple and reliable, easy to install and maintain, and the torsion spring has a low cost, which can effectively control the overall cost of the device.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. A dust filter is installed at the air inlet on the front side of the dehumidifier casing, near the first chamber, and is supported by a support component on the inner wall of the air inlet. When air enters from the air inlet, the dust filter can efficiently adsorb dust and other impurities in the air, preventing dust from entering the dehumidifier and accumulating at the air inlet and inside. This ensures normal air circulation within the dehumidifier, improves the efficiency of air entering the dehumidifier, and also ensures that the dehumidification components inside the dehumidifier can function fully, maintaining the overall dehumidification function of the dehumidifier, extending the service life of the dehumidifier, and improving its effect and reliability in regulating air humidity in different scenarios. 2. When airflow generates wind, the drive impeller rotates under the influence of the wind. Through belt transmission, it drives the drive wheels connected to both ends of the upper support roller to rotate, thereby causing the upper and lower support rollers to rotate synchronously, driving the dust filter to circulate. This design requires no additional electrical energy, truly achieving self-cleaning without any external force, reducing operating costs and energy consumption. Attached Figure Description

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.

[0027] Example 1: Reference Figure 1 and Figure 2 A self-cleaning filtration device for a dehumidifier unit includes a dehumidifier housing 1, wherein a steam heat exchanger is fixedly installed inside the dehumidifier housing 1, and the steam heat exchanger has a conventional structure, which will not be described in detail here; wherein an air inlet 11 is opened on the front side of the dehumidifier housing 1, and an air outlet 12 is opened on the bottom surface of the steam heat exchanger; a guide plate 2 is fixedly installed on the inner wall of the dehumidifier housing 1, and a first chamber 13 is opened on the left side of the guide plate 2 and a second chamber 14 is opened on the right side; A dust filter 3 is provided on the front side of the dehumidifier housing 1, located on the side of the air inlet 11 near the first chamber 13. A support member 4 is provided on the inner wall of the air inlet 11 to support the dust filter 3. When the gas enters the dehumidifier housing 1 from the air inlet 11, it first flows through the dust filter 3. At this time, the dust filter 3 intercepts dust and other impurities in the air, preventing them from entering the device and accumulating. Subsequently, the gas continues to flow to the steam heat exchanger. Under the action of the heat exchanger, the moisture in the gas is evaporated. The treated dry gas then flows out from the bottom of the steam heat exchanger, completing the entire air dehumidification process.

[0028] Reference Figure 2The inner wall of the first chamber 13 is fixedly installed with a flow collector 5 and a second drive unit 6 that controls the wind force entering the flow collector 5. The guide plate 2 has a clearance notch 21 for one end of the flow collector 5 to be inserted. The second drive unit 6 is a conventional airflow distribution valve device, which will not be described in detail here. The flow collector 5 can effectively gather the gas entering from the air inlet 11, and then stably transfer the gathered gas to the second chamber 14, making full preparations for subsequent actions.

[0029] Reference Figure 2 The support member 4 includes an upper support roller 41 rotatably connected to the front side of the dehumidifier housing 1 in the horizontal direction, and a lower support roller 42 arranged parallel to the upper support roller 41 in the vertical direction. The dust filter 3 is sleeved on the outer circumferential surface of the upper support roller 41 and the lower support roller 42. The dehumidifier housing 1 is provided with a rotating member 8 that drives the upper support roller 41 and the lower support roller 42 to rotate in the direction of their own axis. During normal operation, the upper support roller 41 and the lower support roller 42 can drive the dust filter 3 to operate under the drive of the rotating member 8, so that the dust in the air is not attached to one place on the dust filter 3, thereby improving the utilization rate of the dust filter 3.

[0030] Reference Figure 3 and Figure 4 The rotating component 8 includes a drive wheel 81 rotatably connected to both ends of the upper support roller 41, a drive impeller 82 rotatably connected to the inner wall of the second chamber 14, and a belt 83 connecting the drive wheel 81 and the drive impeller 82. Since the belt 83 is wound around the drive impeller 82 and the drive wheel 81, the rotation of the drive impeller 82 will drive the belt 83 to perform cyclical motion along a specific trajectory. During the motion, the belt 83 will transmit power to the two drive wheels 81, so that the two drive wheels 81 will rotate along their respective axial directions under the combined action of the friction and tension of the belt 83. When the two drive wheels 81 start to rotate, they will transmit rotational power to the upper support roller 41 and the lower support roller 42, thereby driving the upper support roller 41 and the lower support roller 42 to rotate; the rotation of the upper support roller 41 and the lower support roller 42 will drive the dust filter 3 to operate in a predetermined direction and speed, thereby realizing the dynamic adjustment of the dust filter 3.

[0031] Reference Figure 3 and Figure 5 A cleaning brush 15 is provided on the front side of the dehumidifier housing 1 away from the lower support roller 42. During the continuous operation of the dust filter 3, the cleaning brush 15 will continuously and stably clean the dust attached to its surface, peeling the dust off the dust filter 3, thereby ensuring that the dust filter 3 always maintains good ventilation performance and filtration effect.

[0032] Reference Figure 3A dust collection box 7 is detachably installed on the inner wall of the first chamber 13, located above the second drive unit 6. The dust collection box 7 is used to collect the dust that falls off when the cleaning brush 15 cleans the dust filter 3. When the dust collected in the dust collection box 7 reaches a certain amount, the staff can remove the dust collection box 7 from the inner wall of the first chamber 13 for thorough cleaning and dust removal, and then reinstall it in its original position.

[0033] Reference Figure 5 An elastic element 9 is provided on the top surface of the cleaning brush 15. The elastic element 9 is a torsion spring 91 fixedly sleeved on the outer circumference of the cleaning brush 15, and the two ends of the torsion spring 91 are fixedly connected to the inner wall of the dehumidifier housing 1. The torsion spring 91 enables the cleaning brush 15 to have a rotational force to rotate towards the dust filter 3, thereby ensuring that the cleaning brush 15 can always maintain a close and appropriate contact with the dust filter 3 during operation, so as to achieve a high-efficiency and stable cleaning effect.

[0034] The implementation principle of this application embodiment is as follows: When the dehumidifier is in normal operation, outside air enters the dehumidifier through the air inlet 11, and the dust filter 3 efficiently adsorbs dust due to its own characteristics. At the same time, the drive impeller 82 rotates, and through the transmission action of the belt 83, it drives the drive wheel 81 to rotate synchronously. The rotation of the drive wheel 81 is further transmitted to the upper support roller 41 and the lower support roller 42, causing them to rotate around their own axis, thereby driving the dust filter 3 to operate continuously. During this process, the cleaning brush 15 performs continuous and stable cleaning of the dust adhering to the surface of the operating dust filter 3.
