Detailed ways

The present invention first provides an air treatment device. FIG. 1 is a schematic structural diagram of an air treatment device according to an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view of an air treatment device according to an embodiment of the present invention. The dashed arrows indicate the approximate direction of airflow.

Referring to FIGS. 1 and 2 , the air treatment apparatus 1 of the present invention includes a casing 10 . The housing 10 is provided with an air inlet and an air outlet 13. The air outlet 13 is used to communicate with the room. In a specific embodiment, the number of air inlets may be one, and the air inlets may be communicated with indoors or outdoors. In another specific embodiment, the number of air inlets may also be two or more. For example, in the embodiment shown in FIG. 1 , the number of air inlets is two, which includes a The indoor air inlet 11 and the outdoor air inlet 12 for communicating with the outdoors to introduce fresh air. The indoor air inlet 11 and/or the outdoor air inlet 12 can be selectively opened or closed through the damper, so as to selectively allow indoor return air and/or outdoor fresh air to enter the air handling device 1 and be sent out after being processed by the air handling device 1 .

It should be noted that the indoor in the embodiment of the present invention refers to the indoor environment space where the air handling device 1 is located, and the outdoor in the embodiment of the present invention refers to the outdoor environment space.

The air handling apparatus 1 further includes a fan 21 , a water storage tank 31 for containing water, and a drum 41 .

The fan 21 is arranged in the casing 10 and is used to drive the airflow to flow from the air inlet to the air outlet 13 . The fan 21 may be a centrifugal fan, an axial fan or a cross-flow fan.

The water storage tank 31 is disposed in the casing 10 , that is, in the air flow path in the casing 10 .

The drum 41 is rotatably disposed in the water storage tank 31 and includes a plurality of rotating disks 412 disposed on the rotating shaft 411 thereof. The drum 41 is configured to take out the water in the water storage tank 31 through the rotating disk 412 during rotation, so as to wash the airflow through the water adhering to the rotating disk 412 when the airflow flows through the drum 41 .

Specifically, when the drum 41 rotates, part of the water in the water storage tank 31 can adhere to the rotating disk 412 and be taken out with the rotation of the rotating disk 412 . When the airflow passes through the drum 41 and contacts the water on the rotating disk 412, impurities, fluff, water-soluble harmful gases and other pollutants in the airflow can be dissolved in the water, thereby realizing the water cleaning of the airflow. The rotating disc 412 provides a reliable and large contact area for the air flow and the water, and the distribution of the water on the rotating disc 412 is relatively uniform, so it can ensure that the water and the air flow are fully and effectively contacted, and the purification effect and purification of the air flow are improved. efficiency.

It can be understood that the height of the drum 41 in the water storage tank 31 can be set such that when the water in the water storage tank 31 reaches the highest water level, at least part of the drum 41 is above the water surface of the water storage tank 31 so that at least part of the drum 41 is above the water surface. The segment is in the airflow flow path so that at least a portion of the drum 41 is submerged in water when the water in the water storage tank 31 reaches a minimum level so that the water can be brought out as the drum rotates.

The water level in the water storage tank 31 can be obtained by existing methods such as a liquid level sensor, a magnetic float, etc. When the liquid level in the water storage tank 31 is lower than the minimum water level, the user can be prompted to the water storage tank 31 through a display screen, a buzzer, etc. Add water inside.

In some embodiments, the air treatment device 1 further includes a driving mechanism 42 for driving the drum 41 to rotate. The drive mechanism 42 may include a motor and gear assembly. The motor may be arranged on the housing for outputting driving force. The gear assembly is connected between the motor and the rotating shaft 411 of the drum 41 , and is used to transmit the driving force output by the motor to the rotating shaft 411 , thereby causing the drum 41 to rotate. Both ends of the rotating shaft 411 can be rotatably supported on the two side walls of the water storage tank 31 through a bearing, respectively.

The applicant realizes that there is a problem in using the drum 41 for water cleaning of the air flow. After the air treatment device 1 is used for a period of time, certain pollutants may accumulate on the rotating disk 412. The accumulation of dirt becomes thicker and thicker, which affects the life of the rotating disk 412 and the ability of the rotating disk 412 to adhere to water, thereby affecting the purification effect of the airflow. To this end, the air handling device 1 of the present application further includes a cleanliness detection device for detecting the cleanliness of the rotating disk and an automatic cleaning device 80 for cleaning the rotating disk 412 in a controlled manner. In this way, the dirty state of the rotating disk 412 can be acquired in time by the cleanliness detection device. When the cleanliness of the rotating disk 412 is low, the dirt is more serious, and the dirt on the rotating disk 412 can be cleaned by the automatic cleaning device 80, thereby realizing the self-cleaning of the drum 41, prolonging its service life, and ensuring It has good water washing ability for a long time.

3 is a schematic structural diagram of an automatic cleaning device in a cleaning state according to an embodiment of the present invention, and FIG. 4 is a schematic structural diagram of an automatic cleaning device in a non-cleaning state (ie, idle state) according to an embodiment of the present invention. Referring to FIGS. 3 and 4 , in some embodiments, a plurality of rotating disks 412 are passed through the rotating shaft 411 and are arranged at intervals, each rotating disk 412 includes a transparent detection area 4129 , and the detection area of each rotating disk 412 is at The projections in the plane perpendicular to the axis of rotation 411 coincide.

Further, the cleanliness detection device may include a light transmitter 71 for emitting light and a light receiver 72 for receiving light, the light transmitter 71 and the light receiver 72 are respectively disposed on the drum 41 in a direction parallel to the rotation axis 411 and the straight line where the light transmitter 71 and the light receiver 72 are located passes through the detection area 4129 of each rotating disk 412, so as to judge the light transmittance of the detection area 4129 according to the light received by the light receiver 72, so as to determine the light transmittance of the detection area 4129 according to the The light transmittance determines the cleanliness of the rotating disk 412 .

In the present application, a transparent detection area 4129 is provided on each rotating disk 412 , and the projections of the detection area 4129 of each rotating disk 412 in a plane perpendicular to the rotation axis 411 are coincident. Therefore, only a pair of light emitters 71 and light receivers 72 can be arranged on both sides of the drum 41 to effectively detect the cleanliness of all the rotating disks 412 , which reduces the number and structure of cleanliness testing devices and facilitates cleanliness testing. installation of the device.

In some embodiments, the detection zone 4129 is an annular detection zone concentric with the rotation axis 411 . In these embodiments, the rotating disks 412 may be straight disk-like structures arranged in parallel. In other embodiments, the projection of the detection area 4129 on a plane perpendicular to the rotation axis 411 is an annular shape concentric with the rotation axis 411 . In these embodiments, the rotating disk 412 may be a curved disk-like structure. Therefore, no matter where the drum 41 is rotated, the cleanliness of the rotating disk 412 can be detected by the cleanliness detection device even during the rotation of the drum 41 .

In some embodiments, a plurality of rotating disks 412 are arranged in parallel, and each rotating disk 412 has two end faces disposed opposite to each other. The automatic cleaning device 80 is provided on the side of the drum 41 in the radial direction so as to be in direct contact with the end face of each rotating disk 412 . The automatic cleaning device 80 is configured to move in a controlled manner toward the direction close to the drum 41 to a cleaning position in contact with the end surface of the rotating disk 412 when the cleanliness of the rotating disk 412 is less than or equal to the first minimum cleanliness, so that the rotating disk 412 rotates during the rotation process. During the cleaning of the rotating disk 412 , when the cleanliness of the rotating disk 412 is greater than or equal to a preset standard cleanliness, the rotating disk 412 is controlled to move away from the drum 41 to an initial position on the radial side of the drum 41 .

Therefore, when the drum 41 does not need to be cleaned, the automatic cleaning device 80 is located on the radial side of the drum 41 and does not have any influence on the rotation of the drum 41 . When the automatic cleaning device 80 is in the cleaning position, each end face of each rotating disk 412 can be in direct contact with the automatic cleaning device 80 . Therefore, the rotating disk 412 can be cleaned more thoroughly and comprehensively, and the rotating disk 412 can be cleaned more thoroughly. cleaning efficiency and cleaning effect.

In some embodiments, the rotating shaft 411 of the drum 41 extends in the horizontal direction, and the air inlet is located at the radial outer side of the drum 41, so that the airflow entering the casing 10 through the air inlet flows to the drum 41 along the radial direction of the drum 41, and passes through the air inlet. The gap between the two adjacent rotating disks 412 flows through the drum 41 , so that the air flow is washed with water by the water adhering to the rotating disks 412 . Specifically, a gap is formed between every two adjacent rotating disks 412, and the air flow can flow through the gap between the two adjacent rotating disks 412 when it flows to the drum 41 in the radial direction of the drum 41, and the drum 41 hardly It produces any resistance to the airflow, so it hardly affects the air outlet speed of the air outlet 13 .

Further, the automatic cleaning device 80 is arranged above the drum 41 so as to be far away from the water storage tank 31, so it will not be affected by the water in the water storage tank 31, nor will it produce a large resistance to the flow of the airflow, thereby reducing the impact on the airflow. influence of flow rate.

In some embodiments, the plurality of rotating disks 412 are arranged at equal intervals, and each rotating disk 412 has the same thickness. The automatic cleaning device 80 may be any one of a brush, a nozzle and an ultrasonic cleaning device. Specifically, in the embodiments shown in FIGS. 3 and 4 , the automatic cleaning device 80 may include a plurality of brushes 81 arranged at intervals along the rotation axis 411 . The thickness of the brush 81 is equivalent to the distance between the two adjacent rotating disks 412 . When the automatic cleaning device 80 is in the cleaning position, the plurality of brushes 81 can be respectively inserted into the plurality of gaps formed by the plurality of rotating discs 412 arranged at intervals. In addition, the brush 81 located in the gap between the two adjacent rotating disks 412 can reliably contact the opposite end faces of the two rotating disks 412, and the two rotating disks 412 will not squeeze the brush 81. The pressure action prevents the brush 81 from being deformed.

Further, the length of the brush 81 may be slightly larger than the radius of the rotating disk 412 . The distance that the automatic cleaning device 80 moves downward is set so that when the automatic cleaning device 80 is in the cleaning position, the bottom end of the brush 81 is equal to or lower than the height of the rotating shaft 411, so as to ensure that the cleaning range of the brush 81 can cover the rotation The entire area of the disk 412 further improves the comprehensiveness of cleaning the rotating disk 412, and avoids the problem that the center of the rotating disk 412 cannot be cleaned.

In other embodiments, the automatic cleaning device 80 may further include a nozzle and a water pump. The nozzles are disposed toward the drum and communicate with the interior of the water storage tank. The water pump is arranged on the pipeline between the nozzle and the water storage tank, and is used for pumping the water in the water storage tank to the nozzle, and spraying it to the drum through the nozzle, so as to use the water in the water storage tank to clean the drum.

In still other embodiments, the automatic cleaning device 80 may also be an ultrasonic cleaning device, and the ultrasonic cleaning device is disposed in the water storage tank 31 for emitting ultrasonic waves and using ultrasonic waves to clean the drum 41 .

FIG. 5 is a schematic structural view of a rotating disk according to an embodiment of the present invention, and FIG. 6 is a schematic enlarged view of part A in FIG. 5 . In some embodiments, each end surface of the rotating disk 412 is provided with densely arranged ribs 4123 to form densely arranged slots 4124 on the end surface. Compared with the flat surface, the slot 4124 not only has a larger surface area, but also can accommodate more water, and has a strong holding capacity for water under the action of capillary suction. Therefore, the densely arranged ribs 4123 and slots 4124 not only greatly increase the total area of the rotating disk 412 that can be in contact with the airflow, but also effectively increase the amount of water attached to the entire end face, so that there is sufficient A lot of water is in contact with the airflow, which further improves the purification efficiency and purification effect.

Further, the center of each rotating disk 412 is provided with a connecting hole 4121 for the rotating shaft 411 to pass through. Two flanges 4125. That is, two flanges 4125 are respectively disposed at the two peripheral edges of the connecting hole 4121 , and each flange 4125 protrudes from the end surface of the rotating disk 412 . Each flange 4125 has an annular cylindrical shape.

Further, the oppositely arranged flanges 4125 of two adjacent rotating disks 412 abut to form a constant gap between the two adjacent rotating disks 412. In this way, during the rotation of the drum 41, the gap between the two adjacent rotating disks 412 changes or even disappears due to factors such as shaking and offset of the rotating disk 412, so as to avoid the problem of changing or even disappearing the gap between the two adjacent rotating disks. The airflow between 412 and the airflow purification effect have an impact. At the same time, the arrangement of the flanges 4125 also increases the contact area between each rotating disk 412 and the rotating shaft 411 , improves the support stability of the rotating disk 412 , and prevents it from shaking relative to the rotating shaft 411 during rotation.

Since the flange 4125 is located at the center of the rotating disk 412 and the diameter of the rotating disk 412 is relatively large, simply relying on the flange 4125 may not be able to effectively prevent the outer periphery of the rotating disk 412 from shaking or offsetting. To this end, in some embodiments, each end surface of each rotating disk 412 is provided with a distance column 4126 protruding from the end surface, and the distance columns on the opposite end surfaces of two adjacent rotating disks 412 are provided with distance columns 4126 . 4126 abut to form a constant gap between two adjacent rotating disks 412 . Since the spacer column 4126 is located on the end surface, the spacer column 4126 of the two rotating disks 412 can have a good supporting effect on the entire disk body of the rotating disk 412 after contacting, thereby effectively preventing the drum 41 from rotating during the rotation process. The shaking, offset and other factors of the disks 412 cause the gap between two adjacent rotating disks 412 to change or even disappear, so as to avoid affecting the airflow and the airflow purification effect between the two adjacent rotating disks 412 .

In some embodiments, each rotating disk 412 is provided with a plurality of honeycomb holes for retaining water. It is understandable that, compared with the structural design such as ribs and grooves, the honeycomb holes hold a larger amount of water, so the total amount of water carried out by the rotating disk 412 can be increased, and the purification effect and purification efficiency of the air flow can be further improved. With the continuous rotation of the drum 41, the water kept in the honeycomb holes is constantly renewed, so as to maintain a good water cleaning ability for a long time.

In some embodiments, the cleanliness detection device is further configured to controllably detect the cleanliness of the water in the water storage tank 31 . The air handling device 1 further includes a prompting device 90, and the prompting device 90 is used to controllably issue instructions to replace the water storage tank when the cleanliness obtained again after the automatic cleaning device 80 cleans the rotating disk 412 is less than the second minimum cleanliness. 31. Warning signal for water in the 31.

After the automatic cleaning device 80 cleans the rotating disk 412, if the cleanliness obtained by the cleanliness detection device is still relatively low, it indicates that the water in the water storage tank 31 is highly polluted, that is to say, the cleanliness detection device can also The cleanliness of the water in the water storage tank 31 is detected. When the cleanliness of the water is low, the prompting device 90 can issue a prompting signal, thereby prompting the user to replace the water in the water storage tank 31 in time, thereby improving the user's use experience.

Specifically, the prompting device 90 may be a display device, a buzzer, or the like.

The applicant has recognized that when the air temperature is low, especially when fresh air with an outdoor temperature below zero is introduced into the room, it is easy to cause freezing in the water storage tank 31 when the air contacts with water. To this end, in some embodiments, a water tank heating device 33 for heating the water in the water storage tank 31 may be provided in the water storage tank 31, so as to use the heated water to water-clean and/or humidify the airflow. When the heated water comes into contact with the airflow, it transfers heat to the airflow, thereby increasing the temperature of the airflow. That is to say, the present application converts the heating of the airflow into the heating of water, so that the purification, humidification and temperature rise of the airflow are carried out simultaneously when the airflow and the water are in contact. The air is humidified and water washed, and it can compensate for the air temperature and assist heating.

Further, the water tank heating device 33 can be arranged at the bottom of the water storage tank 31 to directly contact the water after the water storage tank 31 is filled with water to transfer heat to the water. This method has higher heat transfer efficiency and faster heating speed. quick. At the same time, it can also be ensured that when there is a small amount of water in the water storage tank 31, the water can still be efficiently heated by direct contact.

Specifically, the water tank heating device 33 may be a heating rod, a heating wire, or the like.

In some embodiments, the air treatment device 1 further includes an ultraviolet generating device 34 for emitting ultraviolet rays into the water storage tank 31 to sterilize the water in the water storage tank 31 . The ultraviolet generating device 34 can be arranged in the water storage tank 31 . In this way, the ultraviolet rays emitted by the ultraviolet generating device 34 can be transmitted to the water storage tank 31 in a short path, and the loss of ultraviolet rays is less, and the sterilization effect is improved.

In some embodiments, the housing 10 is further provided with a mist separation net 29 for dehumidifying the air flowing therethrough. In addition, on the air flow path from the air inlet to the air outlet 13 , the mist shielding net 29 is located downstream of the drum-type water washing device. When high humidity is not needed in the room, the air flow from the water washing device can be dehumidified through the mist separation net 29, so that the air flow into the room is not only cleaned by water, but also has a low humidity, which will not affect the overall humidity of the indoor air.

Specifically, the opening and closing state and/or the opening degree of the mist separation net 29 can be adjusted by the driving mechanism.

The present application also provides an air conditioner. 7 is a schematic structural diagram of an air conditioner according to an embodiment of the present invention. The air conditioner 100 of the present application may include a cabinet 200 and the air treatment device 1 described in any of the above embodiments.

Specifically, the casing 200 is provided with an air inlet 301 for introducing airflow thereinto. The air outlet 13 of the air handling device 1 is connected to the air inlet 301 to introduce the air treated by the air handling device 1 into the casing 200 . Therefore, the air flow introduced into the cabinet 200 through the air handling device 1 is the air flow after water washing and/or humidification, which improves the quality of indoor air and improves the humidity of the indoor air.

In some embodiments, the air conditioner 100 further includes a jet device 300, which is used to controllably cause the air flow outside of the air conditioner to flow into the interior of the air conditioner and send out through the jet outlet, and make the air flow sent out through the jet outlet match the flow through the jet outlet.
