[0041] In combination Figures 1 to 7 As shown in the drawings, the utility model provides a ducted air conditioner, including shell 100, heat exchanger 200, water pan 300 and water receiving box 400. Heat exchanger 200 is arranged in the shell. When the ducted air conditioner is installed horizontally, the water pan 300 is located below the heat exchanger 200, and the water pan 300 has a first side end 301 close to the bottom end of the heat exchanger 200. The water pan 300 includes a bottom disc body 310 and at least one first surrounding baffle 320 extending in a first direction, and the first surrounding baffle 320 is provided with a first drain connector 321 located at the first side end 301 and communicating with the inside of the water pan 300. The water receiving box 400 extends in a second direction and is sleeved on the first side end 301 and has an open top end when the ducted air conditioner is installed vertically, wherein the first drain connector 321 is located in the water receiving box 400.

[0042] Optionally, the inside of the shell 100 defines a heat exchange cavity, and the heat exchanger 200 is arranged obliquely in the heat exchange cavity. Further, the shell 100 includes a mounting plate, and the heat exchanger 200 is arranged on the upper side of the inside of the mounting plate. When the ducted air conditioner is installed horizontally, the heat exchanger 200 is located above the mounting plate, i.e., the orthographic projection of the heat exchanger on the mounting plate.

[0043] Optionally, the heat exchange cavity is provided with the water pan 300. The water pan 300 is arranged on the mounting plate. When the ducted air conditioner is installed horizontally, the water pan 300 is located below the heat exchanger 200, and the orthographic projection of the heat exchanger 200 on the bottom disc body 310 covers the bottom disc body 310. Further, the area of the bottom disc body 310 is greater than or equal to the area of the orthographic projection of the heat exchanger 200 on the bottom disc body 310.

[0044] The water pan 300 has a first side end 301, and comprises a bottom disc body 310 and a first surrounding baffle 320 extending in a first direction. The bottom end of the heat exchanger 200 is arranged close to the first side end 301. When the ducted type air conditioner is installed horizontally, the bottom disc body 310 is arranged horizontally, and the first surrounding baffle 320 is provided with a first water outlet joint 321, which can guide the condensed water collected in the water pan 300 to the outside. When the ducted type air conditioner is installed vertically, the bottom disc body 310 is arranged vertically.

[0045] Optionally, the ducted type air conditioner further comprises a water receiving box 400. The water receiving box 400 can be sleeved on the outer periphery of the first side end 301 through an opening. In this way, when the ducted type air conditioner is installed vertically, the water receiving box 400 can be sleeved on the first side end 301. Thus, the condensed water generated on the heat exchanger 200 can drip or flow downward into the water receiving box 400, so as to realize the collection of the condensed water when the ducted type air conditioner is installed vertically, and improve the safety of the ducted type air conditioner.

[0046] Optionally, the water pan 300 further comprises a second surrounding baffle 330, a third surrounding baffle and a fourth surrounding baffle. The first surrounding baffle 320, the second surrounding baffle 330, the third surrounding baffle and the fourth surrounding baffle are arranged around the periphery of the bottom disc body 310. The first surrounding baffle 320 and the third surrounding baffle are arranged oppositely, and the second surrounding baffle 330 and the fourth surrounding baffle are arranged oppositely. The second surrounding baffle 330 is located at the first side end.

[0047] When the ducted type air conditioner is installed vertically, the condensed water generated on the side of the heat exchanger 200 facing the first side end 301 drips or flows downward onto the second surrounding baffle 330 of the water pan 300 and into the water receiving box 400. The condensed water generated on the side of the heat exchanger 200 away from the first side end 301 drips or flows downward onto the surface of the bottom disc body 310 and further flows onto the second side plate. The condensed water flowing onto the second side plate flows into the water receiving box 400 through the gap between the inner plate surface of the corresponding side plate of the water receiving box 400.

[0048] Optionally, the water receiving box 400 extends in a second direction. The second direction is the length direction of the bottom disc body 310. The length direction of the heat exchanger 200 also extends in the second direction or intersects with the second direction.

[0049] Optionally, the first water outlet joint 321 is completely located in the water receiving box 400. In this way, the water pan 300 can be integrally received, and the collection effect of the condensed water can be ensured.

[0050] Optionally, the water receiving box 400 is integrally formed.

[0051] Optionally, the surface of the heat exchanger 200 is coated with a hydrophilic coating. By coating the surface of the heat exchanger 200 with a hydrophilic coating, the condensed water generated can flow down along the surface of the heat exchanger 200, and then flow to the edge of the bottom end of the heat exchanger and fall into the water pan 300 or the water box 400.

[0052] Specifically, the hydrophilic coating includes one or more of a silicon-based organic-inorganic hydrophilic coating film, a hydrophilic modified silica, titanium dioxide, and a hydrophilic resin. Among them, the hydrophilic resin can provide the durability of the hydrophilic coating.

[0053] Alternatively, the surface of the heat exchanger 200 is not coated with a hydrophilic coating.

[0054] In the above technical solution, in order to adapt to the horizontal or vertical installation of the ducted air conditioner, the heat exchanger is arranged obliquely. When the ducted air conditioner is installed horizontally, the water pan is used to collect the condensed water generated by the heat exchanger; when the ducted air conditioner is installed vertically, the water pan also becomes vertical with the change of the installation direction, so that the condensed water cannot be collected. The side end of the water pan close to the bottom end of the heat exchanger is defined as the first side end, and when the ducted air conditioner is installed vertically, the water box is sleeved outside the first side end, and the first drain connector is covered in the water box, so that the water in the water pan can drip into the water box through the first drain connector or other side edges of the water pan, and the condensed water generated by the heat exchanger can also drip into the water box, thereby realizing the collection of the condensed water of the heat exchanger.

[0055] In the above optional embodiment of the ducted air conditioner, the first box plate 410 of the water box 400 faces the first enclosing plate 320 and is provided with a second drain connector 411 communicating with the inside of the water box 400.

[0056] In this scheme, the second drain connector 411 provided on the first box plate 410 can realize the drainage of the water box 400.

[0057] Specifically, the second drain connector 411 can be externally connected to a drain pipe, so as to guide the collected condensed water outwards to avoid the condensed water overflowing and splashing everywhere outside the shell 100. Optionally, the drain pipe can be extended to the outside for drainage, or extended to the drain hole of the washing machine or the bathroom inside the room.

[0058] Optionally, the second drain connector 411 is integrally formed with the first box plate 410.

[0059] Alternatively, the second drain connector 411 is fixed to the first box plate 410 by welding, gluing or the like.

[0060] Optionally, the first box plate 410 is provided with a second drain hole, and the diameter of the second drain hole matches the inner diameter of the second drain connector 411.

[0061] In the alternative embodiment of the above ducted air conditioner, the bottom box plate 420 of the water collecting box 400 is arranged towards the water pan 300. The distance between the bottom box plate 420 and the first drainage joint 321 is greater than the distance between the bottom box plate 420 and the second drainage joint 411.

[0062] By setting the distance between the bottom box plate 420 and the first drainage joint 321 greater than the distance between the bottom box plate 420 and the second drainage joint 411, i.e. the second drainage joint 411 is located below the first drainage joint 321, so as to avoid the condensate water from soaking the first side end 301 after gathering in the water collecting box 400.

[0063] Specifically, when the ducted air conditioner is installed vertically, the water collecting box 400 is installed. The bottom box plate 420 is towards the second enclosing plate 330 of the water pan 300, i.e. located below the second enclosing plate 330. In this scheme, the distance between the bottom box plate 420 and the first drainage joint 321 can be the distance between the bottom box plate 420 and the lowest point of the first drainage joint 321; the distance between the bottom box plate 420 and the second drainage joint 411 can be the distance between the bottom box plate 420 and the lowest point of the second drainage joint 411. In this way, the first drainage joint 321 and the second drainage joint 411 can be partially or completely staggered. Not only can it avoid soaking the second enclosing plate 330 and the first enclosing plate 320 located at the first side end 301, but also can avoid soaking the first drainage joint 321, thereby improving the service life of the water pan 300 and the water collecting box 400.

[0064] Alternatively, the water collecting box 400 further comprises at least a second box plate, a third box plate and a fourth box plate. The first box plate 410, the second box plate, the third box plate and the fourth box plate are sequentially and foldably connected and arranged around the circumference of the bottom box plate 420 to enclose a water collecting space.

[0065] In the alternative embodiment of the above ducted air conditioner, the water collecting box 400 has a drainage end 401 accommodating the first drainage joint 321, and the drainage end 401 extends out of the shell 100.

[0066] The formed drainage end 401 can accommodate the first drainage joint 321. By setting the drainage end 401 to extend to the outside of the shell 100, there is no need to extend the corresponding length of the shell 100, and there is no need to modify the structure of the water pan 300, thereby reducing the installation difficulty and structural cost.

[0067] In the scheme, when the ducted air conditioner needs to be installed vertically, the water collecting box 400 is sleeved to the first side end 301. Since the water collecting box 400 has the drainage end 401 accommodating the first drainage joint 321, the length of the formed water collecting box 400 in the second direction is greater than the length of the shell 100. In order to adapt to the horizontal installation requirement of the ducted air conditioner, the drainage end 401 is arranged to extend to the outside of the shell 100, so as to avoid the cost waste caused by the extension length of the shell 100, and the shell body wrapping the drainage end 401 does not need to be arranged on the shell, so that the appearance of the shell 100 can be ensured. Further, in this way, the installation difficulty can be reduced, the installation efficiency can be improved, and the structure and installation cost can be reduced.

[0068] In the optional embodiment of the above-mentioned ducted air conditioner, in combination with Figure 5 As shown, the water collecting box 400 further comprises a shielding plate 430. The shielding plate 430 is detachably covered on the drainage end 401.

[0070] Optionally, the shielding plate 430 is connected with the water collecting box 400 through a clamping structure.

[0071] Alternatively, the shielding plate 430 is adhesively connected with the water collecting box 400.

[0072] Alternatively, the shielding plate 430 is magnetically connected with the water collecting box 400.

[0074] By abutting the second box plate 440 against the bottom disc body 310, noise caused by the collision between the second box plate 440 and the bottom disc body 310 when the ducted air conditioner is vertically installed and operated can be avoided, and the comfort of the user can be improved.

[0075] Optionally, the second box plate 440 is magnetically connected with the bottom disc body 310.

[0076] Alternatively, the second box plate 440 is adhesively connected with the bottom disc body 310.

[0077] In the optional embodiment of the above-mentioned ducted air conditioner, in combination with Figure 1 , Figure 6 and Figure 7As shown, the shell 100 comprises a first side plate 110. The first side plate 110 is arranged corresponding to the drainage end 401, and the first side plate 110 is provided with a first through hole 111 for the drainage end 401 to extend out.

[0078] Through the setting of the first through hole 111, when the ducted air conditioner needs to be installed vertically, the first side plate 110 does not need to be cut again, which reduces the installation difficulty and improves the installation efficiency.

[0079] Alternatively, the first side plate 110 is not provided with the first through hole 111, and manual cutting is performed according to actual installation needs.

[0081] Through the setting of the decorative plate 120, the first through hole 111 can be shielded when the ducted air conditioner is installed horizontally, and the appearance of the first side plate can be improved. At the same time, dust can be prevented from entering the heat exchange cavity through the first through hole 111, the cleanliness of the components such as the heat exchanger 200 inside the heat exchange cavity can be improved, the heat exchange efficiency can be ensured, and the service life can be prolonged.

[0082] Further, when the ducted air conditioner is installed vertically, the installer manually removes the decorative plate 120 so that the drainage end 401 extends out.

[0083] Alternatively, the decorative plate 120 is not provided.

[0084] In the optional embodiment of the above-mentioned ducted air conditioner, the decorative plate 120 is connected with the first side plate through a connecting rib or a buckle.
