Technical Field

[0001] The present application relates to the technical field of air treatment, and in particular to air treatment equipment. Background Art

[0002] Air handling equipment is a device used to adjust the temperature, humidity and air flow rate in a room or a specific enclosed space. It uses a cooling or heating system to circulate air to provide people with a comfortable living or working environment. Air handling equipment currently on the market, such as wall-mounted air conditioners, indoor mobile cooling fans or central air conditioners, usually includes a shell, an air inlet and an air outlet arranged in the shell, and a heat exchanger arranged in the shell for heat exchange with the air.

[0003] At present, the prior art has developed an air handling device that integrates cooling, heating and dehumidification functions. However, this air handling device has multiple heat exchangers and at least four air duct control valves inside. During use, the switching between the cooling mode and the dehumidification mode is achieved by controlling the power of the heat exchanger and the air duct control valve, and the control structure is complex and the control is troublesome.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0005] In order to solve or improve to a certain extent the technical problem that the conversion structure of the cooling mode and the cooling and dehumidification mode of the air handling equipment in the prior art is complicated and the conversion is troublesome, the present invention provides an air handling equipment. The air handling equipment comprises: a shell, the interior of the shell is formed with a second heat exchange cavity and a first heat exchange cavity spaced from each other in the vertical direction; a first heat exchanger, the first heat exchanger is arranged in the first heat exchange cavity; a second heat exchanger, the second heat exchanger is arranged in the second heat exchange cavity, and the second heat exchanger and the first heat exchanger are spaced from each other in the vertical direction; and a baffle, the baffle is movably arranged between the second heat exchanger and the first heat exchanger, wherein when the baffle is converted to the water blocking position, the condensed water passage between the second heat exchanger and the first heat exchanger is blocked, and the air handling equipment can perform the cooling mode and the dehumidification mode at the same time; when the baffle is converted to the water passing position, the condensed water passage between the second heat exchanger and the first heat exchanger is connected, and the air handling equipment can perform the cooling mode.

[0006] It can be understood by those skilled in the art that the air handling device of the present invention includes a housing, a first heat exchanger and a second heat exchanger. Among them, the housing provides a suitable installation area for the first heat exchanger and the second heat exchanger. The second heat exchange chamber inside the housing provides a suitable heat exchange space for the second heat exchanger so that the gas in the second heat exchange chamber reaches a set temperature. The first heat exchange chamber inside the housing provides a suitable heat exchange space for the first heat exchanger so that the gas in the first heat exchange chamber reaches a set temperature. When the baffle is in the water-blocking position, the condensed water condensed by the second heat exchanger flows to the baffle, so that the condensed water will not flow to the first heat exchanger, and the condensed water will not be re-evaporated into the air by the first heat exchanger, ensuring a good air drying effect. When the baffle is in the water-passing position, the condensed water condensed by the second heat exchanger flows directly to the first heat exchanger, and the condensed water flows to the surface of the first heat exchanger, increasing the evaporation area of ​​the condensed water, improving the evaporation efficiency of the condensed water, and only reducing the air temperature without reducing the air humidity in the cooling mode. In addition, by switching the baffle between the water-passing position and the water-blocking position, the air handling equipment can be switched between executing the cooling mode and executing the cooling mode and the dehumidification mode at the same time. The switching structure is simple and easy to control.

[0007] In a preferred technical solution of the above air treatment equipment, the baffle is provided with a through hole, and the through hole is located directly above the first heat exchanger.

[0008] Through the above arrangement, when the baffle is switched to the water-passing position, the condensed water condensed by cooling in the second heat exchanger can accurately flow through the through holes of the baffle to the first heat exchanger located below, thereby improving the efficiency of the condensed water re-evaporating back into the air.

[0009] In a preferred technical solution of the above-mentioned air treatment equipment, a water receiving pan located below the first heat exchanger is provided in the first heat exchange chamber.

[0010] Through the above arrangement, the condensed water condensed by the first heat exchanger flows to the water receiving tray below due to gravity, which is convenient for collecting the condensed water and avoids damage to the air handling equipment due to the condensed water flowing onto the circuit.

[0011] In a preferred technical solution of the above air treatment equipment, the baffle is provided with a guide groove, and the guide groove is communicated with the water receiving tray.

[0012] Through the above arrangement, when the baffle is in the water-blocking position, the guide groove can guide the condensed water on the baffle to the water receiving tray below, which is convenient for collecting the condensed water and also prevents the condensed water from contacting the circuit and causing damage to the air handling equipment.

[0013] In a preferred technical solution of the above-mentioned air treatment equipment, the air treatment equipment further includes a third heat exchanger arranged in the water receiving tray.

[0014] Through the above arrangement, the third heat exchanger can improve the evaporation efficiency of the condensed water in the water receiving tray when dissipating heat, further reduce the decrease in air humidity, and enhance the user's usage experience.

[0015] In a preferred technical solution of the above air handling equipment, the first heat exchanger, the second heat exchanger and the third heat exchanger are in the same refrigeration system.

[0016] Through the above arrangement, the first heat exchanger, the second heat exchanger and the third heat exchanger in the same refrigeration system can be controlled to switch between heat absorption and heat dissipation at the same time, with high conversion efficiency and convenient control.

[0017] In a preferred technical solution of the above-mentioned air treatment equipment, one of the first heat exchanger and the second heat exchanger is configured to absorb heat, and the other of the first heat exchanger and the second heat exchanger is configured to dissipate heat.

[0018] Through the above arrangement, when the first heat exchanger absorbs heat, the second heat exchanger dissipates heat. When the first heat exchanger dissipates heat, the second heat exchanger absorbs heat. Only one of the first heat exchanger and the second heat exchanger needs to be controlled to control the other, which is convenient for control.

[0019] In the preferred technical solution of the above-mentioned air treatment equipment, the air treatment equipment also includes: a first fan, which is arranged in the first heat exchange cavity and opposite to the first heat exchanger; and / or a second fan, which is arranged in the second heat exchange cavity and opposite to the second heat exchanger.

[0020] Through the above-mentioned arrangement, the first fan increases the air flow rate in the first heat exchange cavity, speeds up the speed at which the first heat exchanger contacts the air, and improves the heat exchange efficiency of the first heat exchanger. The second fan increases the air flow rate in the second heat exchange cavity, speeds up the speed at which the second heat exchanger contacts the air, and improves the heat exchange efficiency of the second heat exchanger. In addition, the first fan is arranged relative to the first heat exchanger, further speeds up the speed at which the first heat exchanger contacts the air, and further improves the heat exchange efficiency of the first heat exchanger. The second fan is arranged relative to the second heat exchanger, further speeds up the speed at which the second heat exchanger contacts the air, and further improves the heat exchange efficiency of the second heat exchanger.

[0021] In the preferred technical scheme of the above-mentioned air treatment equipment, the second heat exchange chamber includes an upper air outlet and an upper air inlet, the first heat exchange chamber includes a lower air outlet and a lower air inlet, and the second heat exchange chamber and the first heat exchange chamber are connected through a vent; the air treatment equipment also includes: a first air valve, the first air valve is arranged on the shell, and the first air valve is configured to control the synchronous opening and closing of the upper air inlet and the lower air outlet; a second air valve, the second air valve is arranged on the shell, and the second air valve is configured to control the opening and closing of the vent; wherein, when the first air valve synchronously opens the upper air inlet and the lower air outlet, the second air valve closes the vent, so that the air treatment equipment executes a cooling mode, a heating mode, or a cooling mode and a dehumidification mode at the same time; when the first air valve synchronously closes the upper air inlet and the lower air outlet, the second air valve opens the vent, so that the air treatment equipment executes a dehumidification mode.

[0022] Through the above-mentioned arrangement, the upper air outlet provides a channel for air to flow out of the second heat exchange chamber. The upper air inlet provides a channel for air to flow into the second heat exchange chamber. The lower air outlet provides a channel for air to flow out of the first heat exchange chamber. The lower air inlet provides a channel for air to flow into the first heat exchange chamber. The vent enables the air in the second heat exchange chamber and the first heat exchange chamber to communicate with each other. When the first air valve synchronously opens the upper air inlet and the lower air outlet, the second air valve closes the vent, so that the air handling device can execute the cooling mode, the heating mode, or the cooling mode and the dehumidification mode at the same time. Correspondingly, when the first air valve synchronously closes the upper air inlet and the lower air outlet, the second air valve opens the vent, so that the air handling device can execute the dehumidification mode. It can be seen that by controlling the first air valve and the second air valve, the air handling device can be controlled to switch between the dehumidification mode and other working modes, and the control structure is simple and the control is convenient.

[0023] In the preferred technical solution of the above air treatment equipment, the air treatment equipment further comprises a driving assembly disposed on the housing and used to control the movement of the baffle. Through the above arrangement, the driving assembly can control the baffle to switch between the water blocking position and the water passing position, so that the air treatment equipment has automatic control performance and avoids errors caused by manual control.

The upper air outlet 122 and the lower air inlet 111 are located on the other side of the housing 1. The upper air inlet 121 is arranged opposite to the upper air outlet 122. The lower air inlet 111 is arranged opposite to the lower air outlet 112. Figure 1 In the orientation shown, the upper air inlet 121 and the lower air outlet 112 are located on the left side of the housing 1. The upper air outlet 122 and the lower air inlet 111 are located on the right side of the housing 1. The shapes of the upper air inlet 121, the upper air outlet 122, the lower air inlet 111, the lower air outlet 112 and the vent 132 can be, but not limited to, circular or square. The upper air inlet 121 and the lower air outlet 112 are connected to the indoor air. The upper air inlet 121 and the lower air outlet 112 can also be connected to the outdoors through air ducts according to actual needs. The upper air outlet 122 faces the user, so that the user can quickly feel the required air flow.

[0039] Continue to see Figure 1 In one or more embodiments, a partition 13 is fixedly provided inside the housing 1. Figure 1 In the orientation shown, the partition 13 is horizontally fixed in the middle position inside the housing 1. The second heat exchange chamber 12 is located on the upper side of the partition 13, and the first heat exchange chamber 11 is located on the lower side of the partition 13. The vent 132 is provided on the partition 13. The vent 132 enables the air in the second heat exchange chamber 12 and the first heat exchange chamber 11 to communicate with each other. The partition 13 is also provided with a water flow hole 131 for condensed water to flow to the first heat exchanger 51. The water flow hole 131 is directly opposite to the top of the first heat exchanger 51.

[0040] Continue to see Figure 1In one or more embodiments, the first heat exchanger 51 and the second heat exchanger 52 are both fixedly disposed inside the housing 1. The first heat exchanger 51 is disposed in the first heat exchange cavity 11. The second heat exchanger 52 is disposed in the second heat exchange cavity 12. The second heat exchanger 52 and the first heat exchanger 51 are spaced apart from each other in the vertical direction. The first heat exchanger 51 is located near the lower air inlet 111 and is opposite to the lower air inlet 111. The second heat exchanger 52 is located near the upper air inlet 121 and is opposite to the upper air inlet 121. One of the first heat exchanger 51 and the second heat exchanger 52 is configured to absorb heat, and the other of the first heat exchanger 51 and the second heat exchanger 52 is configured to dissipate heat.

[0041] Continue to see Figure 1 In one or more embodiments, the air handling device 100 further includes a baffle 2. The baffle 2 is movably disposed between the second heat exchanger 52 and the first heat exchanger 51. When the baffle 2 is switched to the water-passing position, the condensed water passage between the second heat exchanger 52 and the first heat exchanger 51 is connected, and the air handling device 100 can perform a cooling mode. Figure 2 Schematic diagram of the structure of the air treatment equipment of the present invention when the baffle is switched to the water retaining position. Figure 2 In one or more embodiments, when the baffle 2 is switched to the water blocking position, the condensate water passage between the second heat exchanger 52 and the first heat exchanger 51 is cut off, and the air handling device 100 can simultaneously execute the cooling mode and the dehumidification mode. The baffle 2 switches between the water blocking position and the water passing position, and can disconnect or connect the condensate water passage between the first heat exchanger 51 and the second heat exchanger 52 to adjust the humidity of the air, with a simple structure and convenient control.

[0042] Continue to see Figure 1 In one or more embodiments, the baffle 2 is rotatably connected to the partition 13. The rotatable connection between the baffle 2 and the partition 13 may be, but is not limited to, a hinge connection or a swivel joint connection. A gap is left between the baffle 2 and the inner wall of the housing 1 to facilitate the rotation of the baffle 2 in the housing 1 without damaging the housing 1 and the baffle 2. The area of ​​the baffle 2 is larger than the mouth area of ​​the water flow hole 131, so that the baffle 2 can cover the water flow hole 131 when it is switched to the water flow position.

[0043] Figure 3 Schematic diagram of the structure of the baffle of the air treatment equipment of the present invention. Figure 3In one or more embodiments, the baffle 2 is provided with a plurality of through holes 21 arranged at intervals from each other. The number of through holes 21 can be set to 2, 3 or other suitable numbers according to actual needs, so as to accelerate the flow of condensed water to the first heat exchanger 51. The baffle 2 is also provided with a guide groove 22. The guide groove 22 is arranged in a direction perpendicular to the rotation axis of the baffle 2. The number of guide grooves 22 is the same as the number of through holes 21. The through hole 21 is arranged at one end of the guide groove 22. A plurality of guide grooves 22 correspond to and are connected to a plurality of through holes 21 one by one. One end of the guide groove 22 away from the through hole 21 is connected to the water receiving tray 6 of the air treatment device 100. The communication method between the guide groove 22 and the water receiving tray 6 can be but is not limited to water pipe communication or groove communication. Based on Figure 2 In the orientation shown, when the baffle 2 is switched to the water blocking position, the baffle 2 is tilted and turned toward the second heat exchanger 52. The through hole 21 on the baffle 2 is located higher than the position of the end connected to the water receiving pan 6 in the horizontal direction, so that the condensed water condensed by the second heat exchanger 52 is guided into the water receiving pan 6 by the inclined guide groove 22 due to gravity, thereby blocking the condensed water from flowing toward the first heat exchanger 51. Figure 1 In the orientation shown, when the baffle 2 is switched to the water-passing position, the position of the through hole 21 on the baffle 2 is lower than the position of the end connected to the water receiving pan 6 in the horizontal direction. The through hole 21 is directly opposite to the water flow hole 131. The through hole 21 is located directly above the first heat exchanger 51, so that the condensed water condensed by the second heat exchanger 52 flows to the first heat exchanger 51 through the guide groove 22 of the baffle 2, the through hole 21 and the water flow hole 131 of the partition 13 in sequence due to gravity.

[0044] Continue to see Figure 1In one or more embodiments, the first heat exchanger 51 is arranged below the second heat exchanger 52, so that the condensed water condensed when the second heat exchanger 52 absorbs heat can flow to the first heat exchanger 51 under the action of gravity. The structure is simple and easy to manufacture. The first heat exchanger 51 includes a plurality of first heat exchange plates (not shown in the figure) arranged in a vertical direction. The second heat exchanger 52 includes a plurality of second heat exchange plates (not shown in the figure) arranged obliquely. The plurality of first heat exchange plates are arranged at intervals on the outside of the first heat exchanger 51. The plurality of second heat exchange plates are arranged at intervals on the outside of the second heat exchanger 52. During operation, when the second heat exchanger 52 absorbs heat and the first heat exchanger 51 dissipates heat, the water vapor in the second heat exchange chamber 12 condenses on the second heat exchange plate to form condensed water. Under the action of gravity, the condensed water flows along the second heat exchange plate to the first heat exchange plate. By utilizing the principle of heat absorption by vaporization of condensed water, the condensed water can cool down the first heat exchanger 51, accelerate the heat dissipation speed of the first heat exchanger 51, and improve the refrigeration efficiency of the refrigeration system 101 of the air handling device 100. In addition, in the cooling mode, the condensed water flows to the first heat exchanger 51 and vaporizes back into the air, avoiding air dryness and providing a good user experience. Multiple first heat exchange plates correspond one-to-one to multiple through holes 21, so that the condensed water on the baffle 2 can be evenly distributed to each first heat exchange plate, improving the heat dissipation efficiency of the first heat exchanger 51, and increasing the contact area between the condensed water and the air, accelerating the vaporization of the condensed water back into the air. The first heat exchange plate has a first guide surface. The second heat exchange plate has a second guide surface. When the baffle 2 is switched to the water-passing position, the top of the first guide plate abuts against the position of the baffle 2 close to the through hole 21, so that the first guide surface is connected to the baffle 2, so that the condensed water on the baffle 2 flows smoothly to the first guide surface through the through hole 21, thereby improving the efficiency of the condensed water flow.

[0045] In one or more embodiments, the air treatment device 100 also includes a drive assembly (not shown in the figure) disposed on the housing 1 and used to control the movement of the baffle 2. The drive assembly includes a rotary motor (not shown in the figure) and an angle limiter (not shown in the figure). The rotary motor and the angle limiter are disposed on the housing 1. The output shaft of the rotary motor is fixedly connected to the rotating shaft of the baffle 2 so that the rotary motor drives the baffle 2 to switch between the water retaining position and the water passing position. The angle limiter is also electrically connected to the rotary motor. The sensor of the angle limiter detects the rotation angle of the baffle 2 and sends a signal to control the rotation angle of the output shaft of the rotary motor, thereby controlling the rotation angle of the baffle 2, making the movement of the baffle 2 more precise, improving the accuracy of the flow of condensed water, and thus improving the accuracy of the air humidity control of the air treatment device 100.

[0046] Continue to see Figure 1In one or more embodiments, a water receiving pan 6 located below the first heat exchanger 51 is provided in the first heat exchange chamber 11. The water receiving pan 6 is fixedly connected to the lower side of the interior of the outer shell 1. The water receiving pan 6 has a water storage chamber for storing water. The top of the water receiving pan 6 has an opening connected to the water storage chamber. The first heat exchange plate of the first heat exchanger 51 extends into the water storage chamber through the opening of the water receiving pan 6. During operation, when the first heat exchanger 51 absorbs heat, the condensed water condensed on the first heat exchange plate flows along the first guide surface to the water receiving pan 6 under the action of gravity, which is convenient for the collection of condensed water. On the one hand, it avoids damage to the circuit due to the condensed water contacting the circuit. On the other hand, the collected condensed water can avoid re-evaporation into water vapor and return to the air, thereby ensuring a better dehumidification effect.

[0047] Continue to see Figure 1 In one or more embodiments, the air treatment device 100 further includes a third heat exchanger 53 disposed in the water receiving tray 6. The third heat exchanger 53 is located in the water storage cavity of the water receiving tray 6. The third heat exchange plate of the third heat exchanger 53 can fully contact the condensed water in the water receiving tray 6, thereby improving the heat exchange efficiency between the condensed water and the third heat exchanger 53.

[0048] Figure 6 Schematic diagram of the structure of the refrigeration system of the air handling equipment of the present invention. Figure 6In one or more embodiments, the air handling device 100 further includes a refrigeration system 101. The first heat exchanger 51, the second heat exchanger 52 and the third heat exchanger 53 are in the same refrigeration system 101. The first heat exchanger 51, the second heat exchanger 52 and the third heat exchanger 53 are connected by a heat exchange tube 1012. A heat exchange medium flows through the heat exchange tube 1012. The heat exchange medium may be, but is not limited to, Ra. The refrigeration system 101 further includes a compressor 1011, a four-way valve 1014, an electronic expansion valve 1013 and a solenoid valve 1015. The third heat exchanger 53 is connected in parallel with the solenoid valve 1015 and then connected in series with the compressor 1011 to form a first series circuit. The first heat exchanger 51, the second heat exchanger 52 and the electronic expansion valve 1013 are connected in series to form a second sub-series circuit. The first series circuit and the second series circuit are connected in parallel through the four-way valve 1014. When the first heat exchanger 51 switches between heat absorption and heat dissipation, the four-way valve 1014 changes the flow direction of the heat exchange medium, so that the second heat exchanger 52 can switch between heat dissipation and heat absorption, and the switch is convenient. The compressor 1011 is used to increase the pressure and temperature of the heat exchange medium, so that the high-pressure and high-temperature heat exchange medium circulates in the refrigeration system 101, thereby realizing the transfer of heat. The compressor 1011 is arranged in the first heat exchange chamber 11. The electronic expansion valve 1013 is used to adjust the flow of the heat exchange medium. The solenoid valve 1015 is used to control the opening and closing of the third heat exchanger 53. The first heat exchanger 51 and the second heat exchanger 52 in the same refrigeration system 101 can be controlled to switch between heat absorption or heat dissipation at the same time, with high conversion efficiency and convenient control. In addition, when the air handling device 100 is in heating mode, the second heat exchanger 52 dissipates heat, the upper air outlet 122 blows out hot air, and the first heat exchanger 51 in the same refrigeration system 101 absorbs heat, increases the temperature of the heat exchange medium, and improves the heating efficiency. When the air handling device 100 is in cooling mode, the second heat exchanger 52 absorbs heat, the upper air outlet 122 blows out cold air, and the first heat exchanger 51 in the same refrigeration system 101 dissipates heat, thereby reducing the temperature of the heat exchange medium and improving the refrigeration efficiency.

[0049] Continue to see Figure 1 In one or more embodiments, the first air valve 3 is disposed on the housing 1. The first air valve 3 is configured to control the synchronous opening and closing of the upper air inlet 121 and the lower air outlet 112. The first air valve 3 is located near the upper air inlet 121 and the lower air outlet 112. The first air valve 3 includes a plurality of first air guide plates 31. The plurality of first air guide plates 31 are rotatably connected to the housing 1 and are spaced apart from each other at the upper air inlet 121 and the lower air outlet 112. Based on Figure 1In the orientation shown, a plurality of first air guide plates 31 are arranged from top to bottom with intervals between them.

[0057] Continue to see Figure 1 In one or more embodiments, the air treatment equipment 100 also includes an auxiliary heating device 8 disposed in the second heat exchange cavity 12. The auxiliary heating device 8 may be, but is not limited to, a PCT heater or a resistance wire heater. When the second heat exchanger 52 dissipates heat, the auxiliary heating device 8 starts heating, which can increase the temperature of the second heat exchange cavity 12 and improve the heating efficiency of the air treatment equipment 100. The PTC heater specifically includes a plurality of heat dissipating fins and a positive temperature coefficient thermistor (Positive Temperature Coefficient, PTC) arranged alternately with each other. The plurality of heat dissipating fins are all connected to the positive temperature coefficient thermistor. Gaps are left between the plurality of heat dissipating fins, so that the air can be evenly and fully heated.

[0058] Continue to see Figure 1 In one or more embodiments, the air treatment device 100 further includes a humidifying water box 9 fixedly disposed inside the housing 1. The humidifying water box 9 is located in the second heat exchange chamber 12 and can provide moisture to the air.

[0059] Continue to see Figure 1In one or more embodiments, the air handling device 100 further includes a controller 102. The controller 102 is electrically connected to the first drive motor of the first air valve 3, the second drive motor of the second air valve 4, the first heat exchanger 51, the second heat exchanger 52, the first fan 71, the second fan 72, the auxiliary heating device 8 and the driving assembly.

[0060] Below, combined with the attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 and attached Figure 5 The working steps of the air treatment device 100 of the present invention are described in detail.

[0061] When the air handling device 100 is in the heating mode, the controller 102 controls the first fan 71 and the second fan 72 to start blowing, controls the first drive motor to open the upper air inlet 121 and the lower air outlet 112, controls the second drive motor to close the vent 132, and controls the drive assembly to drive the baffle 2 to switch to the water-passing position. The lower air inlet 111 is connected to the lower air outlet 112, and the upper air inlet 121 is connected to the upper air outlet 122. Air flows into the first heat exchange chamber 11 from the lower air inlet 111, and then flows out of the first heat exchange chamber 11 from the lower air outlet 112. Air also flows into the second heat exchange chamber 12 from the upper air inlet 121, and then flows out of the second heat exchange chamber 12 from the upper air outlet 122. The controller 102 controls the first heat exchanger 51 to absorb heat, the second heat exchanger 52 to dissipate heat, the auxiliary heating device 8 to heat, and the upper air outlet 122 to blow out hot air.

[0062] When the air handling device 100 switches from the heating mode to the dehumidification mode, the controller 102 controls the first drive motor to close the upper air inlet 121 and the lower air outlet 112, and also controls the second drive motor to open the vent 132. The baffle 2 is maintained in the water-passing position. The air flows into the first heat exchange chamber 11 from the lower air inlet 111, then flows into the second heat exchange chamber 12 from the vent 132, and finally flows out of the second heat exchange chamber 12 through the upper air outlet 122, so that the upper air outlet 122 blows out dry air. It is only necessary to control the first air valve 3 and the second air valve 4 to control the switching of the air handling device 100 between the heating mode and the dehumidification mode. The switching structure is simple, the switching steps are simple, and it is easy to use.

[0063] When the air handling device 100 is in the cooling mode, the controller 102 controls the first fan 71 and the second fan 72 to start blowing, controls the first drive motor to open the upper air inlet 121 and the lower air outlet 112, and the second drive motor to close the vent 132. The baffle 2 is maintained in the water-passing position. The lower air inlet 111 is connected to the lower air outlet 112, and the upper air inlet 121 is connected to the upper air outlet 122. Air flows into the first heat exchange chamber 11 from the lower air inlet 111, and then flows out of the first heat exchange chamber 11 from the lower air outlet 112. Air also flows into the second heat exchange chamber 12 from the upper air inlet 121, and then flows out of the second heat exchange chamber 12 from the upper air outlet 122. The controller 102 controls the first heat exchanger 51 to dissipate heat, the second heat exchanger 52 to absorb heat, the third heat exchanger 53 to dissipate heat, and the upper air outlet 122 to blow out cold air. The condensed water on the second heat exchanger 52 flows into the first heat exchanger 51 under the action of gravity. The temperature of the first heat exchanger 51 for heat dissipation is high. The condensed water vaporizes and evaporates into the air on the first heat exchanger 51, ensuring that the humidity in the air remains unchanged, giving the user a good experience. The condensed water flowing into the water receiving tray 6 is heated to 60°C by the third heat exchanger 53, further accelerating the vaporization and evaporation of the condensed water back into the air.

[0064] When the air handling device 100 switches from the cooling mode to the cooling mode and the dehumidification mode, the controller 102 controls the driving assembly to switch the baffle 2 to the water blocking position. The condensed water condensed by the second heat exchanger 52 flows onto the baffle 2, and the guide groove 22 of the baffle 2 guides the condensed water into the water receiving tray 6, so that the upper air outlet 122 blows out dry cold air. The switching of the air handling device 100 between the cooling mode and the cooling mode and the dehumidification mode can be controlled by only controlling the baffle 2. The switching structure is simple, the switching steps are simple, and the use is convenient.

[0065] When the air handling device 100 is in the air supply humidification mode, the controller 102 controls the second fan 72 to start blowing, the controller 102 controls the first drive motor to close the upper air inlet 121 and the lower air outlet 112, the second drive motor to open the vent 132, the humidification water box 9 is opened, and the baffle 2 is switched to the water passing position. The air flows into the first heat exchange chamber 11 from the lower air inlet 111, then flows into the second heat exchange chamber 12 from the vent 132, and finally flows out of the second heat exchange chamber 12 through the upper air outlet 122, so that the upper air outlet 122 blows out the wind with water vapor.

[0066] When the air handling device 100 is in the auxiliary heating and humidification mode, the controller 102 controls the second fan 72 to start blowing, the controller 102 controls the first drive motor to close the upper air inlet 121 and the lower air outlet 112, the second drive motor to open the vent 132, the humidification water box 9 is opened, and the baffle 2 is switched to the water-passing position. The air flows into the first heat exchange chamber 11 from the lower air inlet 111, then flows into the second heat exchange chamber 12 from the vent 132, and finally flows out of the second heat exchange chamber 12 through the upper air outlet 122. The controller 102 controls the auxiliary heating device 8 to start heating, so that the upper air outlet 122 blows out higher temperature wind with water vapor.

[0067] When the air handling device 100 is in the heating and humidification mode, the controller 102 controls the second fan 72 to start blowing, the controller 102 controls the first drive motor to close the upper air inlet 121 and the lower air outlet 112, the second drive motor to open the vent 132, the humidification water box 9 is opened, and the baffle 2 is switched to the water-passing position. The air flows into the first heat exchange chamber 11 from the lower air inlet 111, flows into the second heat exchange chamber 12 from the vent 132, and finally flows out of the second heat exchange chamber 12 through the upper air outlet 122. The controller 102 controls the first heat exchanger 51 to absorb heat and the second heat exchanger 52 to dissipate heat, so that the upper air outlet 122 blows out high-temperature wind with water vapor.

[0068] When the air handling device 100 is in full heat humidification mode, the controller 102 controls the second fan 72 to start blowing, the controller 102 controls the first drive motor to close the upper air inlet 121 and the lower air outlet 112, the second drive motor to open the vent 132, the humidification water box 9 is opened, and the baffle 2 is switched to the water-passing position. The air flows into the first heat exchange chamber 11 from the lower air inlet 111, then flows into the second heat exchange chamber 12 from the vent 132, and finally flows out of the second heat exchange chamber 12 through the upper air outlet 122. The controller 102 controls the first heat exchanger 51 to absorb heat and the second heat exchanger 52 to dissipate heat, and the auxiliary heating device 8 to start heating, so that the upper air outlet 122 blows out the highest temperature wind with water vapor.
