Detailed ways

The present invention first provides an air treatment apparatus. FIG. 1 is a schematic structural diagram of an air treatment apparatus according to an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view of an air treatment apparatus according to an embodiment of the present invention.

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.

An air duct connecting the air inlet and the air outlet 13 is formed in the housing 10, and the air duct is provided with a fan 21 for driving the air flow from the air inlet to the air outlet 13, a water storage tank 31 for accommodating water, and a rotatable fan 21. The drum 41 is disposed in the water storage tank 31 , and the air flow in the air duct flows to the drum 41 along the radial direction of the drum 41 . That is, the direction in which the airflow flows to the drum 41 is perpendicular to its rotation axis.

The drum 41 includes a rotating shaft 411 and a plurality of rotating discs 412 which are arranged on the rotating shaft 411 and are arranged at intervals along the rotating shaft 411 . Therefore, 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 a direction perpendicular to the rotation axis of the drum 41, and the drum 41 It hardly produces any resistance to the airflow, so it hardly affects the air outlet speed of the air outlet 13 .

FIG. 3 is a schematic structural diagram of a rotating disk according to an embodiment of the present invention. Further, each rotating disk 412 is provided with a plurality of honeycomb holes 4122 for retaining water. The drum 41 is arranged to take out the water in the water storage tank 31 through the honeycomb holes 4122 during rotation, so that when the air flows through the drum 41 through the gap between the two adjacent rotating disks 412, the water brought out through the honeycomb holes 4122 Water scrubbing and/or humidifying the air stream. Specifically, when the rotating disk 412 is in contact with water, the honeycomb holes 4122 of the rotating disk 412 below the water surface are filled with water, and when the part of the honeycomb holes 4122 moves out of the water surface with the rotation of the rotating disk 412, at least part of the water will remain in the honeycomb holes 4122 Inside.

That is to say, when the drum 41 is rotating, part of the water in the water storage tank 31 is kept in the honeycomb holes 4122 on the rotating disk 412 , and is taken out with the rotation of the rotating disk 412 . When the airflow flows toward the drum 41 along the radial direction of the drum 41 , it can flow through the gap between the two adjacent rotating disks 412 . During this process, the air flow contacts the water held in the honeycomb holes 4122, and solid pollutants such as particulate matter and fluff in the air flow, as well as water-soluble harmful gases such as formaldehyde and benzene, can be dissolved in the water, so as to achieve the purpose of water washing of the air flow. . At the same time, the airflow can take away part of the water vapor, thereby being humidified. It is understandable that, compared with the structural design of ribs, grooves, etc., the honeycomb holes 4122 hold a larger amount of water, so the 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 held in the honeycomb holes 4122 is constantly renewed, so as to maintain a good water cleaning ability for a long time.

It can be understood that when the honeycomb holes 4122 are not arranged next to each other, other areas of the rotating disk 412 except the honeycomb holes 4122 can also bring out part of the water, and the water brought out from this part can also be mixed with the airflow. contact and water scrub and/or humidify the airflow.

Specifically, the honeycomb hole 4122 is preferably a through hole with a polygonal cross-section, so as to increase its holding capacity for water. In other embodiments, the honeycomb holes 4122 may also be pipe perforations with a circular, triangular or irregular cross-section.

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 for transmitting 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.

In some embodiments, the air duct is further provided with a partition 43 adjacent to the top of the drum 41, and the partition 43 is used to guide all the airflow entering the air duct through the air inlet to the drum 41, so that all the airflow in the air duct passes through The water cleaning and/or humidification of the drum improves the comprehensiveness of the purification and/or humidification treatment of the air flow.

In some embodiments, the rotating disk 412 is a curved panel extending in a wave shape, so that a plurality of ridges 4123 and a plurality of recesses 4124 are formed on both sides of the rotating disk 412 . Thus, the surface area of the rotating disk 412 is increased.

Further, each ridge 4123 and each recess 4124 are provided with a plurality of honeycomb holes 4122 . As a result, the number of honeycomb holes 4122 is increased, which not only increases the total area of the rotating disk 412 that can be in contact with the airflow, but also increases the amount of water held by the entire rotating disk 412, so that there is enough water in contact with the airflow, which further improves the The purification efficiency and purification effect are improved.

There are various ways in which the rotating disk 412 can be extended in a wave shape. In some embodiments, the rotating disk 412 may include a plurality of sector-shaped disk areas 412a, each of which is provided with a plurality of ridges 4123 and a plurality of concave grooves 4124, and a plurality of ridges 4123 and a plurality of grooves and grooves. 4124 all extend along the radial direction of the rotating disk 412 and are parallel to each other. That is, the rotating disk 412 may be curved and extended in a wavy manner along the circumferential direction thereof in sections.

FIG. 4 is a schematic structural diagram of a rotating disk according to another embodiment of the present invention. In other embodiments, the convex ridges 4123 may be annular convex ridges concentric with the rotating disk 412 , the concave grooves 4124 may be annular concave grooves concentric with the rotating disk 412 , and the radii of the plurality of convex ridges 4123 and the plurality of concave grooves 4124 are equal to gradually increase. That is, the rotating disk 412 is centered on the center of the circle and extends outward in a wavy manner along its radial direction.

Of course, in some alternative embodiments, the rotating disk 412 may also extend along a wave-shaped bend in other ways, which will not be listed here.

In some embodiments, the center of each rotating disk 412 is provided with a connecting hole 4121 for the rotating shaft of the drum 41 to pass through. of the 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 opposite flanges 4125 of two adjacent rotating disks 412 are abutted 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 the gap between the two adjacent rotating disks 412. 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, two sides of each rotating disk 412 are provided with spacer columns 4126 that protrude outward along the direction of the rotating shaft 411 respectively. The posts 4126 abut to form a constant gap between two adjacent rotating disks 412 . That is to say, the distance posts 4126 are arranged on the end face of the rotating disk 412, so the spacing columns 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 During the rotation of the drum 41, the gap between the two adjacent rotating disks 412 changes or even disappears due to the shaking, offset and other factors of the rotating disk 412, so as to avoid the problem of the gap between the two adjacent rotating disks 412. Air flow and air purification effect.

Specifically, the number of the distance posts 4126 may be multiple, and the plurality of distance posts 4126 may be evenly distributed on the end surface of the rotating disk 412 . circle and set at equal intervals.

In some embodiments, the height of each spacer column 4126 on each rotating disk 412 is the same, and the height of the flange 4125 on each rotating disk 412 is the same; on the same rotating disk 412, the distance column 4126 is the same height as flange 4125. Therefore, the size of the gap formed between any two rotating disks 412 is the same, which facilitates the uniformity of the airflow to flow through the drum 41, and further improves the uniformity and purifying effect of purifying the airflow.

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 inlet may be located on the radially outer side of the drum 41 so that the air entering the air duct through the air inlet flows to the drum 41 along the radial direction of the drum 41 and flows through the gap between two adjacent rotating disks 412 through the drum 41 . Specifically, in the embodiment shown in FIG. 1 , the air inlet includes an indoor air inlet 11 and an outdoor air inlet 12 , and both the indoor air inlet 11 and the outdoor air inlet 12 are located radially outside the drum 41 . Therefore, the design of the air duct is simplified, the air flow path between the air inlet and the drum 41 is shortened, and the air flow resistance is reduced.

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 air duct 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 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.

5 is a schematic structural diagram of an automatic cleaning device in a cleaning state according to an embodiment of the present invention, and FIG. 6 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. In some embodiments, each rotating disk 412 includes a transparent detection area 4129 , and the projections of the detection areas of each rotating disk 412 on a plane perpendicular to the rotation axis 411 are coincident.

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.

Specifically, the detection area 4129 may be an annular detection area concentric with the rotation axis 411 .

In some embodiments, the automatic cleaning device 80 may be any of a brush, a nozzle, and an ultrasonic cleaning device.

Specifically, in the embodiments shown in FIG. 5 and FIG. 6 , the automatic cleaning device 80 may include a plurality of brushes 81 arranged at intervals along the direction of the rotating shaft 411 , and the automatic cleaning device 80 is configured so that the cleanliness of the rotating disk 412 is less than When equal to the first minimum degree of cleanliness, it is controlled to move in a direction close to the drum 41 to a cleaning position where its brush is in contact with the end face of the rotating disk 412 to clean the rotating disk 412 during the rotation of the rotating disk 412, When the cleanliness of the disc 412 is greater than or equal to the preset standard cleanliness, the disc 412 is controlled to move in a direction away from the drum 41 to an initial position on the radial side of the drum 41 .

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 .

In some embodiments, the housing 10 is provided with a water filling port, and the water filling port is provided with a water filling box 50 for adding water to the water storage tank 31 , and the water filling box 50 is arranged to be operably hidden in the housing 10 and closed to the water supply. The water port is switched between a closed state and an open state protruding outward from the housing 10 to allow water to flow through the water filling box 50 to the water storage tank 31 . That is, when the water storage tank 31 does not need to be filled with water, the water filling box 50 can be hidden in the housing 10 and close the water filling port, which will not affect the appearance of the housing 10 and cause water to splash out through the water filling port. When the water storage tank 31 needs to be filled with water, the water filling box 50 can be pulled out from the casing 10 to protrude outward from the casing 10 , thereby allowing water to flow to the water storage tank 31 through the water filling box 50 . After the water storage tank 31 is filled with water, the water filling box 50 can be directly pushed into the housing 10 . The entire water adding process does not need to move the water storage tank 31 or other components, and the water adding operation is very simple.

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. The heat exchange air flow out of the heat exchange air flow outlet of the air conditioner 100 is mixed, so as to prevent the air from the air conditioner 100 from being overcooled or overheated, thereby improving the softness of the air output and the user's comfortable experience. That is to say, the jet device 300 is used to introduce into the air conditioner 100 the natural air that has not been heat-exchanged by the heat exchange device of the air conditioner 100 , so as to moderate the outlet air temperature of the air conditioner 100 .

Further, the air inlet 301 may be opened on the jet device 300 of the air conditioner 100 and serve as the air inlet of the jet device 300 . Therefore, the air flow processed by the air handling device 1 can flow out directly through the jet device 300 and be mixed with the heat exchange air flow and then be sent into the room, and the air flow directly sent into the room has been washed and/or humidified by the water in the air handling device 1, There is no need to provide a corresponding purification device and/or a humidification device in the air conditioner 100, which simplifies the structure of the air conditioner 100 body.

Further, the air conditioner 100 may be a cabinet-type air conditioner indoor unit, and the jet device 300 thereof may extend vertically as a whole, so that the jet air outlet matches the shape of the air outlet of the cabinet-type air conditioner indoor unit. In these embodiments, the air inlet 301 can be opened at the bottom of the jet device 300, and the air outlet 13 of the air handling device 1 can be located at the top thereof, so as to facilitate the connection between the air inlet 301 and the air outlet 13.

Of course, in some alternative embodiments, the air inlet 301 can also be a normal air inlet of the air conditioner 100, and the air after being purified and/or humidified by the air treatment device 1 is sent into the casing 200 through the air inlet 301, and passed through the air inlet 301. The heat exchange device of the air conditioner 100 exchanges heat and sends it out.
