Description

Technical Field

[0001] This invention relates to the field of air purification technology, specifically providing an air purification module and an air conditioner. Background Technology

[0002] As living standards improve, air conditioners with humidification functions are becoming increasingly common. However, with prolonged operation, bacteria can easily grow in the humidification module of an air conditioner. As the air conditioner humidifies the air, these bacteria can adhere to the flowing air and spread into the air, posing a potential threat to user safety if the air conditioner operates for an extended period.

[0003] Currently, air purifiers on the market can sterilize the air flowing through a humidifier module. These devices typically add a volatile disinfectant to the liquid water in the humidifier module's water tank, so that the water mist generated by the humidifier contains the disinfectant to sterilize the air flowing through it. However, to reduce the risk to human safety, an appropriate amount of disinfectant needs to be added to the liquid water. This results in the disinfectant in the water mist not effectively killing bacteria growing in the air duct, meaning that bacteria still adhere to the air flowing out of the air conditioner's outlet, thus affecting the air conditioner's sterilization effect.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that existing air purification modules can only sterilize the air flowing through the humidification module, but cannot effectively sterilize the bacteria attached to the airflow path, resulting in the air flowing out of the air outlet of the air conditioner still having bacteria attached, thus affecting the sterilization effect of the air conditioner.

[0013] The bending portion includes a first flange and a second flange. The first flange extends horizontally and its outer edge is sealed to the inner wall of the receiving cavity. The second flange extends vertically and its upper edge is connected to its inner edge. The lower edge of the second flange is positioned such that, when the first flange is sealed to the receiving cavity, the distance between the lower edge of the second flange and the maximum water level in the receiving cavity is equal to a preset spacing threshold.

[0014] Multiple first air guide plates are connected to the outer wall of the second flange. The multiple first air guide plates are configured such that after the bending portion is sealed to the inner wall of the receiving cavity, the inner edge of the multiple first air guide plates abuts against the inner wall of the receiving cavity, the lower edge of the multiple first air guide plates is flush with the lower edge of the second flange, and the multiple first air guide plates are arranged to gradually extend to the right or left from top to bottom along the first flange in the direction from the outside to the inside.

[0015] In the preferred embodiment of the above-mentioned air purification module, the air purification module further includes:

[0016] Multiple second air guide plates are disposed on the inner sidewall of the receiving cavity. The direction in which the multiple second air guide plates extend from the inside to the outside along the first flange from top to bottom is the same as the direction in which the multiple first air guide plates extend from the outside to the inside along the first flange from top to bottom.

[0017] In the preferred embodiment of the above-mentioned air purification module, the sterilization component includes:

[0018] A water mist assembly disposed in the receiving cavity, the water mist assembly being configured to convert the liquid water located in the receiving cavity into a water mist suspended in the receiving cavity; and

[0019] A disinfectant module is disposed in the receiving cavity, the disinfectant module being configured to add a disinfectant to the liquid water.

[0020] In the preferred embodiment of the above air purification module, the water mist component includes:

[0021] A water-spinning component, disposed in the receiving cavity, is rotatably connected to the bottom wall of the receiving cavity. The water-spinning component is configured to throw its internal liquid water toward the inner wall of the receiving cavity, thereby forming a water mist inside the receiving cavity; and

[0022] A drive unit, disposed in the receiving cavity, is used to drive the water-spinning component to rotate relative to the side wall, and the rotation direction of the drive unit is configured to enable the water-spinning component to rotate in the opposite direction to the cyclone.

[0023] In the preferred embodiment of the above-mentioned air purification module, the disinfectant module includes:

[0024] A hydrogen peroxide module is disposed on the bottom wall of the receiving cavity. The hydrogen peroxide module is used to electrolyze the liquid water to generate hydrogen peroxide, so that the liquid water can be mixed with the hydrogen peroxide.

[0025] In the preferred embodiment of the above-mentioned air purification module, the air purification module further includes:

[0026] A filter assembly is disposed at the air outlet. The filter assembly is configured to absorb liquid water in the water mist, so that the disinfectant can be attached to the filter assembly, so that the filter assembly can sterilize the air flowing through it.

[0027] In the preferred embodiment of the above-mentioned air purification module, the filter component includes:

[0028] A bracket, which covers the air outlet; and

[0029] A wet film, which is disposed on the support, is used to absorb liquid water in the water mist.

[0031] In a second aspect, the present invention also provides an air conditioner, the air conditioner including the above-mentioned air purification module.

[0032] When the above technical solution is adopted, the present invention connects an air guide component to the inner wall of the receiving cavity, so that the air flowing through the air inlet can form an air cyclone in the receiving cavity under the action of the air guide component. This allows the air entering the receiving cavity to fully contact the water mist, thereby increasing the content of the disinfectant in the air. Even when the content of disinfectant in the liquid water is low, the disinfectant in the air blown out of the air purification module can effectively kill the bacteria growing on the air duct, thus ensuring the sterilization effect of the air conditioner.

[0040] Preferred embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the specification is described in conjunction with an air conditioner, it is clearly also applicable to fresh air systems, fans, humidifiers, and other household appliances with airflow functions.

Figure 2 This is a half-sectional schematic diagram of an air purification module according to an embodiment of the present invention. Figure 2 This is a top view of a centrifugal rotor according to an embodiment of the present invention. Figure 3 It is along Figure 2 A schematic diagram of the cross section along line AA. Figure 4 It is along Figure 2 A schematic diagram of the partial cut of the BB line.

[0044] To address the problem that existing air purifiers can only sterilize the air flowing through the humidification module, but cannot effectively sterilize bacteria attached to the airflow path, resulting in bacteria still being present in the air flowing out of the air conditioner's outlet, thus affecting the air conditioner's sterilization effect.

[0045] like Figure 1 As shown, see also Figure 3 and Figure 4 The air purification module 100 includes a module body 1, a receiving cavity 2, a sterilization component 5, an air inlet 21, an air outlet 22, and an air guide component 3. Specifically, the air purification module 100 is installed in the air duct of an air conditioner. The receiving cavity 2 is located inside the module body 1 and is used to contain liquid water. The sterilization component 5 is located in the receiving cavity 2 and is configured to form a water mist containing a sterilizing agent inside the receiving cavity 2. The air inlet 21 is located on the side wall of the receiving cavity 2. The air outlet 22 is located on the top wall of the receiving cavity 2. The air guide component 3 is connected to the side wall of the receiving cavity 2 and communicates with the air inlet 21. The air guide component 3 is configured to form an air cyclone in the air entering the receiving cavity 2. This allows the air entering the containment cavity 2 to form an air cyclone, enabling the air to fully contact the water mist and increase the content of disinfectant in the air flowing through the air purification module 100. This ensures that even when the content of disinfectant in the liquid water is low, the content of disinfectant in the air is still high, so that the air flowing out of the air purification module 100 also contains an appropriate amount of disinfectant. In this way, the air flowing out of the air purification module 100 can kill bacteria growing in the air duct and reduce the risk of disinfectant posing a threat to human safety.

[0046] It should be noted that although the air purification module 100 described above is installed inside the air duct of an air conditioner, this is not limiting. In other embodiments of the present invention, the air purification module 100 can also be installed in the air duct of a fresh air system, or in the air duct of an air purifier. Obviously, it can also be installed in the air duct of a humidifier, but this is not limiting either, as long as the air purification module can be installed in the air duct of a product with a blowing function. In addition, in other embodiments of the present invention, a fan (not shown) can also be provided inside the air purification module 100, and an air duct is provided inside the module body 1 so that the fan can drive air to flow in the air duct. In this case, if the air purification module 100 is combined with a product with a blowing function such as an air conditioner, a fresh air system, or a humidifier, it is not necessary to install the air purification module 100 in the air duct of the air conditioner, fresh air system, or humidifier.

[0047] As one possible implementation method, such as Figure 1 As shown, see also Figure 3 and Figure 4 The air guide assembly 3 includes a bending section and a plurality of first air guide plates 32. Specifically, the bending section includes a first flange 33 and a second flange 31. The first flange 33 extends in the horizontal direction and the outer edge of the first flange 33 is sealed to the inner wall of the receiving cavity 2. More specifically, the connection between the outer edge of the first flange and the inner wall of the receiving cavity 2 is located above the upper edge of the air inlet 21. The second flange 31 extends vertically, with its upper edge connected to its inner edge. The lower edge of the second flange 31 is positioned such that when the first flange 33 is sealed to the inner wall of the receiving cavity 2, the distance between the lower edge of the second flange 31 and the maximum water level of the liquid water in the receiving cavity 2 is equal to a preset spacing threshold. Thus, after the bent portion is in the installation position, air upstream of the air purification module 100 in the air duct enters the air inlet 21 and can enter the receiving cavity 2 through the opening between the lower edge of the second flange 31 and the liquid water, flowing upwards. This arrangement increases the contact distance between the air in the air intake receiving cavity 2 and the water mist containing the disinfectant, allowing the air flowing through the air purification module 100 to fully contact the water mist containing the disinfectant, thereby increasing the content of the disinfectant in the air flowing out of the air purification module 100 and ensuring the sterilization effect of the air purification module 100.

[0048] Continue reading Figure 1 , Figure 3 and Figure 4Multiple first air guide plates 32 are connected to the outer wall of the second flange 31. When the multiple first air guide plates 32 are sealed to the inner wall of the receiving cavity 2 at the bend, after the edges of the multiple first air guide plates 32 near the side wall of the receiving cavity 2 are sealed to the inner wall of the receiving cavity 2, the inner edges of the multiple first air guide plates 32 abut against the inner side wall of the receiving cavity 2, and the lower edges of the multiple first air guide plates 32 are flush with the lower edges of the second flange 31. The multiple first air guide plates 32 are gradually extended to the right from top to bottom along the first flange 33 from the outside to the inside, so that the air entering from the air inlet 21 can form an air cyclone in the receiving cavity 2 under the action of the multiple first air guide plates 32, so as to further increase the contact distance between the air and the water mist, thereby increasing the content of the disinfectant in the air flowing out of the air purification module 100, so as to improve the disinfection effect of the air purification module 100 on the air duct located downstream of the air purification module 100. More specifically, since the bent portion forms a downward air intake channel with the inner wall of the receiving cavity 2, in order to improve the cyclone effect applied to the air by the first air guide plate 32, in this specific implementation, the air inlet 21 is positioned at the upper end of the receiving cavity 2 to increase the distance between the lower edge of the air inlet 21 and the lower edge of the second flange 31. In this way, when factors such as air flow rate and the angle of the air guide plate remain unchanged, the air guiding area of ​​the air guide plate can be increased to enhance the air guiding effect of the air guide plate, thereby improving the cyclone effect of the air entering the receiving cavity 2, and further increasing the content of disinfectant in the air flowing out of the air purification module 100.

[0049] It should be noted that, although the above combination Figure 1 , Figure 3 and Figure 4 The multiple first air guide plates 32 described are arranged to extend gradually to the right from top to bottom along the first flange 33 from the outside to the inside. However, this is not a limitation. In specific implementation of the present invention, those skilled in the art can also arrange the multiple first air guide plates 32 to extend gradually to the left from top to bottom along the first flange 33 from the outside to the inside. Such adjustment does not deviate from the principle of the present invention and therefore will also fall within the protection scope of the present invention.

[0050] Furthermore, despite the above combination Figure 1 , Figure 3 and Figure 4The described air guide assembly 3 is composed of a bent portion and multiple first air guide plates 32, so that the air guide assembly 3 can form an air cyclone when the air enters the receiving cavity 2. However, this is not limiting. In specific implementations of the present invention, those skilled in the art can also configure the air guide assembly 3 as multiple air guide channels connected to the air inlet 21 as needed. Specifically, the multiple air guide channels are configured such that the angle between them and the outer wall of the receiving cavity 2 is less than 90 degrees, and the angles between the multiple air guide channels along the same direction surrounding the outer wall of the receiving cavity 2 are equal, so that the air entering the receiving cavity 2 through the multiple air guide channels can form an air cyclone in the receiving cavity 2. However, this is also not limiting. Without departing from the basic principles of the present invention, those skilled in the art can flexibly choose the specific configuration of the air guide assembly 3 according to the specific application scenario, as long as it can achieve the goal of forming an air cyclone when the air flowing through the air inlet 21 through the air guide assembly 3 enters the receiving cavity 2.

[0051] As one possible implementation method, such as Figure 1 As shown, see also Figure 3 and Figure 4 The air purification module 100 also includes multiple second air guide plates 34, which are evenly distributed on the inner wall of the receiving cavity 2. The multiple second air guide plates 34 extend from the inside out along the first flange 33 from top to bottom, which is the same as the multiple first air guide plates 32 extending from the outside in along the first flange 33 from top to bottom. With this arrangement, when the air cyclone formed inside the receiving cavity 2 moves from bottom to top, the air flow direction is the same as the extension direction of the air guide plates from bottom to top. Therefore, the multiple second air guide plates 34 can further increase the air guiding area of ​​the air purification module 100, thereby further enhancing the air cyclone effect under the action of the multiple second air guide plates 34, and further increasing the content of disinfectant in the air flowing out of the air purification module 100.

[0052] As one possible implementation method, such as Figure 1 As shown, see also Figure 3 and Figure 4 The sterilization component 5 includes a water mist component 51 and a sterilizing agent module 52. The water mist component 51 is disposed in the receiving cavity 2 and is configured to convert liquid water in the receiving cavity 2 into water mist suspended in the receiving cavity 2. The sterilizing agent module 52 is disposed in the receiving cavity 2 and is configured to add sterilizing agent to the liquid water. With the above arrangement, when the water mist component 51 converts the liquid water in the receiving cavity 2 into water mist, the sterilizing agent can also be suspended in the receiving cavity 2 along with the water mist, so that the water mist also contains sterilizing agent.

[0053] As one possible implementation method, such as Figure 1 As shown, see also Figure 3 and Figure 4 The water mist assembly 51 includes a water-spinning component (not labeled) and a drive unit (not shown). The water-spinning component is located inside the receiving cavity 2. Specifically, the water-spinning component is rotatably connected to the bottom wall of the receiving cavity 2 via a rotating shaft 6. More specifically, the water-spinning component has a cavity inside. The cavity has a water inlet near the bottom of the receiving cavity 2 and a water outlet at the end of the cavity away from the bottom of the receiving cavity 2. The position of the water inlet is configured such that when the water level of the liquid water inside the receiving cavity 2 is higher than a preset low threshold, the liquid water can block the water inlet. Thus, when the water-spinning component rotates, the liquid water inside the cavity can move towards the inner wall of the cavity under the action of centrifugal force. Finally, the liquid water is thrown out through the water outlet located on the side wall of the cavity and thrown towards the inner wall of the receiving cavity 2 to form a water mist. A drive unit is located in the receiving cavity 2 and is used to drive the water-spinning component to rotate relative to the side wall of the receiving cavity 2. Specifically, the drive unit is a drive motor, the main body of which is fixedly connected to the bottom of the outer wall of the receiving cavity 2. The output shaft of the drive motor is connected to the rotating shaft 6 so that the drive motor can drive the rotating shaft 6 to rotate, thereby driving the water-spinning component to rotate. More specifically, in the specific implementation of the present invention, the rotation direction of the drive component is configured to make the water-spinning component rotate in the opposite direction to the rotation direction of the air inside the receiving cavity 2, so that the movement direction of the water mist formed by the water-spinning component relative to the receiving cavity 2 is opposite to the movement direction of the air relative to the inside of the receiving cavity 2. Through the above arrangement, the water mist can be made to contact the rotating air more fully, thereby allowing the air flowing through the air purification module 100 to contain more disinfectant, thereby further improving the sterilization effect of the air purification module 100.

[0054] As one possible implementation, in order to enable liquid water to be quickly ejected from the outlet hole under the action of centrifugal force, the sidewall of the cavity is configured to gradually extend outward from the bottom of the receiving cavity 2 to the direction away from the bottom of the receiving cavity 2, so that the liquid water can move towards the outlet hole more quickly under the action of centrifugal force.

[0055] It should be noted that although the water-spinning component described above has a cavity inside, with an inlet at the bottom and an outlet at the top, this is not limiting. In specific implementations of the present invention, a water pump can also be installed inside the receiving cavity 2, a water flow channel can be provided at the axis of the water-spinning component, and an outlet communicating with the water flow channel can be provided circumferentially on the side wall of the water-spinning component. The outlet of the water pump is connected to the inlet through a pipeline so that the water pump can deliver liquid water to the water flow channel, so that when the water-spinning component rotates, the liquid water delivered by the water pump to the water flow channel can be thrown out through the outlet.

[0056] Furthermore, although the water mist assembly 51 described above consists of a water-spraying component and a driving unit, this is not limiting. In other embodiments of the present invention, the water mist assembly 51 can also be an ultrasonic atomizer. However, this is also not limiting. In other aspects of the present invention, the water mist assembly 51 can also be a compression atomizer, in which liquid water is sprayed from a nozzle using compressed air, so that the compressed air can blow the liquid water into fine mist droplets. Obviously, without departing from the basic principles of the present invention, those skilled in the art can flexibly choose the specific configuration of the water mist assembly 51 according to the specific application scenario, as long as the water mist assembly 51 can convert the liquid water located at the bottom of the receiving cavity 2 into water mist suspended in the air.

[0057] Continue reading Figure 1 , Figure 3 and Figure 4 In a specific implementation of this invention, the disinfectant module 52 includes a hydrogen peroxide module, which is located on the bottom wall of the receiving cavity 2. This hydrogen peroxide module is used to generate hydrogen peroxide from the liquid water in the receiving cavity 2 through electrolysis, ensuring that the liquid water is mixed with hydrogen peroxide. This configuration allows the disinfectant module 52 to directly generate disinfectant from liquid water during the operation of the air purifier, avoiding the need for a separate disinfectant dispensing device and reducing the number of parts. Furthermore, it eliminates the need for users to manually add disinfectant to the disinfectant module 52, making air purification more convenient and improving user satisfaction.

[0058] It should be noted that, although the above combination Figure 1 , Figure 3 and Figure 4 The described disinfectant module 52 includes a hydrogen peroxide module, but this is not limiting. In specific implementations of the present invention, the disinfectant module 52 can also be a disinfectant dispensing module. Specifically, the disinfectant module 52 is disposed in the receiving cavity 2 and is used to dispense the disinfectant contained inside the disinfectant module 52 into the liquid water, so that the liquid water in the receiving cavity 2 can be mixed with the disinfectant. The disinfectant can be a bactericidal product with sterilization function against bacteria, viruses and fungi, such as hypochlorous acid disinfectant, chlorhexidine, chlorine dioxide and povidone-iodine.

[0059] Continue reading Figures 1 to 4In a specific embodiment of the present invention, the air purification device further includes a filter assembly 4, which is disposed at the air outlet 22 of the receiving cavity 2. The filter assembly 4 is configured to absorb liquid water from the water mist, allowing hydrogen peroxide to adhere to it. This enables the filter assembly 4 to sterilize the flowing air, ensuring the air purification module 100 can effectively sterilize the air and guarantee its sterilization effect. Specifically, the filter assembly 4 includes a support 41 and a wet membrane 42. The support 41 covers the air outlet 22, and the wet membrane 42 is disposed on the support 41 for absorbing liquid water from the water mist.

[0060] Despite the above combination Figures 1 to 4 The described filter assembly 4 includes a support 41 and a wet membrane 42, but this is not limiting. In specific implementations of the present invention, the filter assembly 4 can be a filter cotton, and obviously the filter assembly 4 can also include activated carbon, synthetic fiber filter screens, and other products with filtration functions.

[0061] As one possible implementation method, such as Figure 1 and Figure 2 As shown, the support 41 includes multiple spiral openings extending outward from its center. The rotation direction of these spiral openings is configured to be the same as the cyclone direction of the air inside the receiving cavity 2. This allows the rotating air in the receiving cavity 2 to move upward to the support 41, further enhancing the cyclone effect under the influence of the spiral openings, thereby increasing the content of disinfectant in the air flowing out of the air purification module 100. Specifically, in this embodiment, the spiral openings rotate clockwise from the center of the support 41 outward along the receiving cavity 2 from bottom to top. However, this is not limiting; those skilled in the art can also configure the spiral openings to rotate counterclockwise from the center of the support 41 outward along the receiving cavity 2 from bottom to top, as long as the rotation direction of the spiral openings is the same as the cyclone direction of the air inside the receiving cavity 2.

[0062] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
