[0002] The duct air conditioner is a concealed air conditioner that is installed in the ceiling of the room. It has the advantages of flexible and concealed installation location and saving indoor space.

[0003] In the related art, when a ducted air conditioner is installed vertically, the heat exchanger of the ducted air conditioner is tilted, and condensed water flows along the heat exchanger into the vertical water receiving surface of the water receiving pan. At the same time, to prevent the water receiving pan from blocking the wind when installed vertically, the vertical water receiving surface of the water receiving pan does not exceed the air inlet.

[0004] In the related art, when the ducted air conditioner is installed vertically, the projection of the heat exchanger on the horizontal plane is not entirely within the water tray, and condensed water may drip outside the water tray. When the fan is working, the air flow blows through the heat exchanger from bottom to top, and the air flow will offset part of the gravity of the condensed water, so that the condensed water tends to flow to the water tray. However, when the fan stops working, the condensed water is easy to drip outside the water tray under the action of gravity. If the condensed water drips into the volute of the fan, it will affect the working condition and service life of the volute, and may even cause a short circuit, fire, and water leakage of the ducted air conditioner, affecting the user experience.

[0036] A ducted air conditioner is a concealed air conditioner that is installed in the ceiling of a room. It has the advantages of flexible and concealed installation location and saving indoor space. More and more home air conditioners are using ducted air conditioners.

[0037] In the related art, the heat exchanger of the ducted air conditioner is tilted, and when installed vertically, condensed water flows along the heat exchanger into the vertical water receiving surface of the water receiving pan. At the same time, to prevent the water receiving pan from blocking the wind when installed vertically, the vertical water receiving surface of the water receiving pan does not exceed the air inlet.

[0038] In the related art, when the ducted air conditioner is installed vertically, the projection of the heat exchanger on the horizontal plane is not entirely within the water tray, and condensed water may drip outside the water tray. When the fan is working, the air flow blows through the heat exchanger from bottom to top, and the air flow will offset part of the gravity of the condensed water, so that the condensed water tends to flow to the water tray. However, when the fan stops working, the condensed water is easy to drip outside the water tray under the action of gravity. If the condensed water drips into the volute of the fan, it will affect the working condition and service life of the volute, and may even cause a short circuit, fire, and water leakage of the ducted air conditioner, affecting the user experience.

[0039] In a first aspect, the present application provides a duct air conditioner.

[0040] Combine Figure 1 As shown, the duct air conditioner provided in this application includes a chassis 1, a fan 2, a water receiving tray 3, a heat exchanger 4 and a water baffle 5.

[0041] The chassis is provided with a heat exchange chamber 101 and a fan chamber 102; the fan 2 is arranged in the fan chamber 102; the heat exchanger 4 is arranged obliquely in the heat exchange chamber 101, and the water receiving tray 3 is arranged at the lower end of the heat exchanger 4 along the gravity direction, and the positive projection of the heat exchanger 4 on the water receiving tray 3 at least partially covers the bottom surface of the water receiving tray 3, and the end of the heat exchanger 4 opposite to the lower end extends toward the side away from the fan chamber 102; the water baffle 5 is rotatably arranged on the side of the heat exchanger 4 close to the fan chamber 102, and the water baffle 5 includes a fixed side and a rotating side, the fixed side is connected to the first side wall of the chassis, and the rotating side rotates around the fixed side according to the state parameters of the duct machine.

[0042] When the duct air conditioner is installed vertically, the fan cavity 102 is located below the heat exchange cavity 101. The heat exchanger 4 is arranged at an angle, and the positive projection of the heat exchanger 4 on the water receiving tray 3 at least partially covers the bottom surface of the water receiving tray 3, so the condensed water on the heat exchanger 4 will flow into the water receiving tray 3 along the heat exchanger 4. In order to avoid the water receiving tray blocking the wind when the duct air conditioner is installed vertically, the vertical water receiving plate of the water receiving tray will not exceed the air inlet of the fan. However, part of the condensed water has a tendency to drip downward under the action of gravity, and the condensed water dripping downward will fall outside the water receiving tray, or even drip into the air outlet of the fan. When the fan 2 is working, the airflow blows from the fan cavity 102 to the heat exchanger 4, and the airflow offsets part of the gravity of the condensed water, so that the condensed water is more inclined to flow to the water receiving tray 3, and is not easy to drip directly from the heat exchanger.

[0043] When the ducted air conditioner is installed vertically, with fan 2 stopped, water baffle 5 rotates close to heat exchanger 4. This catches condensed water dripping from heat exchanger 4, preventing it from entering the volute of fan 2 and affecting its operating condition and service life. This improves the safety of the ducted air conditioner and enhances the user experience. When fan 2 is running, water baffle 5 is kept away from heat exchanger 4 to avoid affecting the air path between fan 2 and heat exchanger 4.

[0044] When the ducted air conditioner is installed vertically, the fan cavity 102 is located below the heat exchange cavity 101 .

[0045] When the ducted air conditioner is installed flat, the fan cavity 102 and the heat exchange cavity 101 are arranged side by side, and the heat exchanger 4 is located above the water receiving tray 3.

[0046] The water receiving tray 3 is used to collect the condensed cold water dripping from the heat exchanger 4, so as to meet the water collection requirements of the ducted air conditioner in both horizontal and vertical installation modes.

[0047] In some embodiments, combined Figure 1 As shown, the water receiving pan 3 includes a vertical water receiving plate 301 near the fan chamber 102. The vertical water receiving plate 301 is tilted toward the side away from the fan chamber 102. When the water baffle 5 is close to the heat exchanger 4, the water baffle 5 is located on the side of the vertical water receiving plate 301 near the heat exchanger 4. The orthographic projection of the rotating side of the water baffle 5 on the bottom surface of the water receiving pan is located within the vertical water receiving plate 301.

[0048] So set up, combined with Figure 1 As shown, when the ducted air conditioner is installed vertically, condensed water from the heat exchanger 4 flows down along the heat exchanger to the bottom of the heat exchanger, where it collects and drips onto the vertically mounted water receiving plate 301. It then flows along the vertically mounted water receiving plate 301 into the water receiving pan 3. Condensed water dripping directly from the heat exchanger 4 falls onto the water baffle 5, along which it flows onto the vertically mounted water receiving plate 301, and then along the vertically mounted water receiving plate 301 into the water receiving pan 3. The provision of the vertically mounted water receiving plate 301 facilitates the collection of condensed water when the ducted air conditioner is installed vertically.

[0049] Combine Figure 1 As shown, a partition 103 is provided between the heat exchange chamber and the fan chamber, and the vertical water receiving plate 301 does not exceed the fan air inlet of the partition 103, so as to avoid the vertical water receiving plate 301 affecting the air path between the fan 2 and the heat exchanger 4.

[0050] In some embodiments, combined Figure 4 As shown, the water tray 3 also includes a flush-mounted water receiving plate 302, a first enclosure, a second enclosure, and a third enclosure. The chassis includes a second sidewall opposite the first sidewall. The flush-mounted water receiving plate 302 is parallel to the second sidewall. The first enclosure and the vertical enclosure 301 are disposed opposite each other along the length of the flush-mounted water receiving plate 302. The second enclosure and the third enclosure are disposed opposite each other along the width of the flush-mounted water receiving plate 302. The flush-mounted water receiving plate 302, the first enclosure, the second enclosure, the third enclosure, and the vertical enclosure 301 together form a water receiving trough.

[0051] So set up, combined with Figure 4As shown, when the ducted air conditioner is mounted flat, condensed water from the heat exchanger 4 flows down along the heat exchanger into the water collection trough. Condensed water dripping directly from the heat exchanger 4 falls onto the flat-mounted water collection plate 302. The provision of the flat-mounted water collection plate 302 facilitates the collection of condensed water when the ducted air conditioner is mounted flat.

[0052] Under some specific engineering conditions, the duct air conditioner needs to have both horizontal and vertical installation methods. In summary, the water collection tray of the duct air conditioner in this application can effectively collect condensate when installed horizontally or vertically, and can be installed horizontally or vertically to meet different installation requirements.

[0053] In some embodiments, combined Figure 4 As shown, the orthographic projection of the water baffle 5 on the second side wall is located in the water receiving pan 3. With this arrangement, when the ducted air conditioner is installed flat, when the water baffle 5 is used to block water, for example, when the water baffle 5 is used to block water when cleaning the heat exchanger, the water receiving pan 3 can more completely collect condensed water dripping from the heat exchanger 4.

[0054] The water baffle 5 is used to receive the condensed water dripping from the heat exchanger 4 and guide the condensed water into the water receiving pan 3 .

[0055] In some embodiments, combined Figure 2 As shown, the water baffle 5 includes a bottom plate 501 opposite to the heat exchanger 4, and the middle part of the bottom plate 501 protrudes toward the direction close to the heat exchanger 4 to form a shape with a high middle and low sides; a partition 103 is arranged between the fan cavity 102 and the heat exchange cavity 101, and a fan outlet 1031 is arranged in the middle part of the partition 103, and the positive projections of the two sides of the lower position of the bottom plate 501 on the partition are located on the outside of the fan outlet 1031.

[0056] When the ducted air conditioner is installed vertically and the water baffle 5 is close to the heat exchanger 4, the bottom plate 501 can receive the condensed water dripping from the heat exchanger 4 to prevent the condensed water from falling into the fan cavity. Figure 3 As shown, the condensed water falling on the water baffle 5 will flow along the surface of the bottom plate 501 to both sides of the bottom plate 501. The water baffle 5 is higher in the middle, and there is less condensation remaining in the middle. This can prevent the condensed water from flowing down from the middle of the water baffle 5 and entering the fan outlet during the swinging of the water baffle 5.

[0057] In some embodiments, combined Figure 2 As shown, the water retaining plate 5 includes a first side plate 502 and a second side plate 503 . The first side plate 502 and the second side plate 503 are relatively arranged on two lower sides of the bottom plate 501 . The fixed side of the bottom plate 501 is rotatably connected to the inner wall surface of the chassis 1 .

[0058] When the ducted air conditioner is installed vertically, with the water baffle 5 positioned close to the heat exchanger 4, the bottom plate 501 can catch condensed water dripping from the heat exchanger 4, preventing it from entering the fan cavity. The first and second side plates 502, 503, together with the bottom plate 501, define the direction of condensed water flow and direct it into the water tray 3. The fixed side of the bottom plate 501 is rotatably connected to the inner wall of the chassis 1, allowing the water baffle 5 to be rotatably mounted within the chassis 1.

[0059] In some embodiments, combined Figure 2 As shown, in the length direction of the water baffle 5, the middle part of the bottom plate 501 of the water baffle 5 is raised toward the direction close to the heat exchanger 4. That is, along the length direction of the water baffle 5, the bottom plate 501 is high in the middle and low on both sides.

[0060] So set up, combined with Figure 3 As shown, the condensed water falling on the water baffle 5 will flow along the surface of the bottom plate 501 to both sides of the bottom plate 501, so as to prevent the condensed water from flowing down from the middle of the water baffle 5 and entering the fan outlet during the swinging process of the water baffle 5.

[0061] For example, since most of the condensed water received by the water baffle 5 is generated when the duct air conditioner is shut down, and the water baffle 5 is close to the bottom of the heat exchanger when the duct air conditioner is shut down, the condensed water is diverted to both sides of the water baffle 5 under the influence of the structure of the water baffle 5 itself, and finally flows into the water receiving tray 3. As the downtime of the duct air conditioner increases, the condensed water in the middle position of the water baffle 5 will become less and less. When the duct air conditioner is started again, in the process of the water baffle 5 rotating from close to the heat exchanger to away from the heat exchanger, there is less condensed cold water in the middle position of the water baffle 5, which can greatly reduce the probability of condensed water dripping into the fan outlet. It can be understood that the fan outlet is provided in the middle of the partition 103, and the fan outlet corresponds to the middle position of the water baffle 5.

[0062] In some embodiments, a fan outlet 1031 is provided in the middle of the partition 103. The airflow generated by the fan 2 is blown toward the heat exchanger 4 along the fan outlet 1031. Figure 3 As shown, the orthographic projections of the first side plate 502 and the second side plate 503 of the water retaining plate 5 on the partition plate 103 are located outside the fan outlet 1031 .

[0063] Since the water baffle 5 is higher in the middle and lower on both sides, most of the condensed water on the water baffle remains on both sides of the water baffle. With this arrangement, during the rotation of the water baffle 5, the remaining condensed water flows down from both sides of the water baffle 5 and will not flow into the fan outlet to damage the fan.

[0064] In some embodiments, the first side plate 502 and the second side plate 503 are folded toward the heat exchanger 4. By providing the first side plate 502 and the second side plate 503, the bottom plate 501 can be enclosed to define the flow direction of the condensed water and guide the condensed water into the water receiving tray 3.

[0065] In some embodiments, combined Figure 1 As shown, the area of ​​the bottom plate 501 of the water retaining plate 5 is greater than or equal to the area of ​​the heat exchanger 4. Such an arrangement can better receive the condensed water dripping from the heat exchanger 4 and prevent the condenser from falling into the air outlet of the fan.

[0066] In some embodiments, the state parameters of the ducted air conditioner include the fan running state and the fan shutdown state. Figure 5 As shown, when the duct air conditioner is installed upright, when the duct air conditioner is in the fan running state, the water baffle 5 is close to the first side wall, and the orthographic projection of the water baffle on the partition is located on the outside of the fan outlet. With this arrangement, the water baffle 5 avoids the fan outlet, which can avoid affecting the air path between the fan and the heat exchanger, and can also prevent residual condensed water from dripping into the fan outlet. When the duct air conditioner is in the fan shutdown state, the water baffle 5 rotates close to the heat exchanger 4, and the orthographic projection of the rotating side on the bottom surface of the water receiving tray 3 is located inside the water receiving tray 3. With this arrangement, the water baffle 5 can catch the condensed water dripping from the heat exchanger 4 and guide the condensed water into the water receiving tray 3, preventing the condensed water from dripping into the volute of the fan 2 and affecting the working state and service life of the volute.

[0067] Optionally, combined Figure 8 As shown, the first side plate 501 of the water baffle 5 is provided with a first fixing hole 5021, and the second side plate 503 is provided with a second fixing hole 5031. The air duct unit also includes a fixing rod, which passes through the first fixing hole 5021 and the second fixing hole 5031 in sequence and is rotatably fixed to the chassis of the air duct unit.

[0068] In some embodiments, when the ducted air conditioner is flush-mounted and the fan is running, the water baffle 5 is positioned close to the first side wall. This arrangement allows the water baffle 5 to avoid obstructing the air path between the fan and the heat exchanger. When the ducted air conditioner is flush-mounted and the heat exchanger is not being cleaned, the water baffle 5 is positioned close to the first side wall or close to the heat exchanger 4.

[0069] In some embodiments, the state parameter of the ducted air conditioner also includes the clean state of the heat exchanger. When the heat exchanger is in the clean state, the water baffle rotates close to the heat exchanger, and the positive projection of the rotating side on the bottom surface of the water receiving tray is located inside the water receiving tray. Figure 6 and Figure 7 As shown, when cleaning the heat exchanger 4, the water baffle 5 is close to the heat exchanger 4. Regardless of whether the duct unit is installed vertically or horizontally, when cleaning the heat exchanger 4, the water baffle 5 is close to the heat exchanger 4.

[0070] Because the heat exchanger of a vertical ducted air conditioner is more susceptible to dust accumulation, when the heat exchanger becomes clogged, the localized flow of condensate becomes uncontrollable, increasing the risk of condensate dripping. To prevent clogged heat exchangers, the heat exchanger needs to be cleaned regularly. A water baffle 5 is provided below the heat exchanger to effectively divert wastewater generated during cleaning into the water pan 3, protecting the fan cavity during cleaning and effectively preventing water leakage from the chassis during cleaning.

[0071] It should be noted that when the air conditioner is in cleaning mode, the water baffle is always kept close to the heat exchanger, allowing the heat exchanger to be flushed. After flushing, a signal is given to the air conditioner to heat at the appropriate temperature and send hot air to the heat exchanger for the appropriate time to dry the water baffle and heat exchanger.

[0072] In summary, the duct machine provided in this application can be installed horizontally or vertically to meet different installation requirements.

[0073] In the case of flat-mounted ducted air conditioner: Figure 4 As shown, the fan chamber 102 and heat exchange chamber 101 are arranged side by side, with the heat exchanger 4 positioned above the water collection tray 3. Condensate from the heat exchanger 4 flows down along the heat exchanger into the water collection trough. Condensate dripping directly from the heat exchanger 4 falls onto the flush-mounted water collection plate 302. The water collection tray 3 effectively collects the condensed water.

[0074] When the ducted air conditioner is installed flat and the fan is running, the water baffle 5 is close to the first side wall. In this way, the water baffle 5 avoids the fan outlet and can avoid affecting the air path between the fan and the heat exchanger.

[0075] When the duct machine is installed flat and the heat exchanger 4 is being cleaned, the water baffle 5 is close to the heat exchanger 4. Figure 7 As shown, clean water is sprayed toward the heat exchanger from the side away from the fan. The water baffle 5 prevents wastewater from splashing toward the fan side and diverts wastewater generated during the heat exchanger cleaning process into the water receiving tray 3. This protects the fan cavity during heat exchanger cleaning and prevents water leakage from the chassis during the cleaning process. When the air conditioner is in cleaning mode, the water baffle remains close to the heat exchanger, allowing it to be flushed. After flushing, a signal is sent to the air conditioner to heat at the appropriate temperature, deliver hot air to the heat exchanger for the appropriate amount of time, and dry the water baffle and heat exchanger.

[0076] In the case of vertical installation of duct machine: Figure 1 As shown, the fan chamber 102 is located below the heat exchange chamber 101. The water baffle 5 is close to the heat exchanger 4 when the fan 2 is stopped, and is away from the heat exchanger 4 when the fan 2 is running.

[0077] When the fan 2 is shut down, the condensed water on the heat exchanger 4 flows down along the heat exchanger to the bottom of the heat exchanger, gathers at the bottom of the heat exchanger and drips onto the vertical water receiving plate 301, and then enters the water receiving pan 3 along the vertical water receiving plate 301. The condensed water dripping directly from the heat exchanger 4 falls on the water baffle 5, and the condensed water flows along the water baffle 5 into the vertical water receiving plate 301, and then enters the water receiving pan 3 along the vertical water receiving plate 301. Along the length direction of the water baffle 5, the bottom plate 501 is high in the middle and low on both sides. The condensed water falling on the water baffle 5 will flow along the surface of the bottom plate 501 to the sides of the bottom plate 501, so as to prevent the condensed water from flowing down from the middle of the water baffle 5 and entering the fan outlet during the swinging process of the water baffle 5. The water receiving pan 3 can collect condensed water well.

[0078] When fan 2 is running, water baffle 5 is close to the first side wall, and its orthographic projection on the partition is located outside the fan outlet. Water baffle 5 avoids the fan outlet, thus avoiding affecting the air path between the fan and the heat exchanger and preventing residual condensed water from dripping into the fan outlet.

[0079] In a second aspect, the present application provides a control method for a ducted air conditioner.

[0080] The control method of the duct air conditioner provided in this application includes the following steps:

[0081] S101, obtaining the working mode of the duct air conditioner.

[0082] The working modes include cooling mode, heating mode and cleaning mode.

[0083] S102: When the ducted air conditioner is in cooling or heating mode, determine the working state of the fan.

[0084] The ducted air conditioner in this application can be installed horizontally or vertically. Condensation water may be generated when the ducted air conditioner is in cooling or heating mode. As described above, when the air conditioner is stopped, the condensation water is likely to drip outside the water collection tray under the action of gravity.

[0085] S103, when the fan is turned off, controlling the water baffle to rotate to a first position, wherein the first position is that the water baffle is close to the heat exchanger.

[0086] If the ducted air conditioner is installed vertically, the water baffle 5 rotates to a position close to the heat exchanger 4. This catches condensed water dripping from the heat exchanger 4, preventing it from entering the volute of the fan 2 and affecting its operating condition and service life. This improves the safety of the ducted air conditioner and enhances the user experience. If the ducted air conditioner is installed horizontally, the water baffle 5 rotates to a position close to the heat exchanger 4 to prevent foreign matter from entering the fan 2. This control method is applicable to both horizontal and vertical installations, eliminating the need for separate control for the two different installation situations, which helps save costs.

[0087] S104, when the fan is running, controlling the water baffle to rotate to a second position, wherein the second position is that the water baffle is away from the heat exchanger.

[0088] When the fan 2 is running, the water baffle 5 is away from the heat exchanger 4 , which can avoid affecting the air path between the fan 2 and the heat exchanger 4 .

[0089] In some embodiments, the control method further includes: controlling the water baffle to rotate to a first position when the ducted air conditioner is in cleaning mode. When the air conditioner is in cleaning mode, the water baffle remains in close proximity to the heat exchanger, allowing the heat exchanger to be flushed. Clean water is sprayed toward the heat exchanger from the side of the heat exchanger away from the fan. The water baffle 5 prevents wastewater from splashing toward the fan side and can divert wastewater generated during the heat exchanger cleaning process into the water receiving pan 3, protecting the fan cavity during heat exchanger cleaning and preventing water leakage from the chassis during the cleaning process.

[0090] Optionally, the ducted air conditioner's operating mode also includes: upon completion of heat exchanger cleaning, sending hot air to the heat exchanger to dry the water baffle and heat exchanger. Upon completion of heat exchanger cleaning, a signal is sent to the air conditioner to heat at an appropriate temperature, sending hot air to the heat exchanger for an appropriate period of time to dry the water baffle and heat exchanger.
