The utility model provides an air conditioner which can be used for a movable board room or a container room, a commodity room and the like.

Referring to fig. 1 to 3, in an embodiment of the present invention, the air conditioner includes:

an inner machine casing 11;

the indoor heat exchanger 20 is arranged in the inner machine shell 11, and the indoor heat exchanger 20 comprises a heat exchange section extending in the vertical direction and/or a heat exchange section extending in an inclined manner; and

and the water pan 31 is arranged in the inner machine shell 11 and is positioned below the indoor side heat exchanger 20, and the projection of the lower end of the heat exchange section extending along the vertical direction and/or the lower end of the heat exchange section extending obliquely on the water pan 31 is positioned in the water pan 31.

In the technical scheme of the utility model, when condensate water is generated on each heat exchange section of the indoor side heat exchanger 20, the condensate water flows downwards to the lower end of the corresponding heat exchange section along the corresponding heat exchange section under the action of gravity and then drips downwards, and because the projection of the lower end of each heat exchange section on the indoor side heat exchanger 20 on the water receiving tray 31 is positioned in the water receiving tray 31, the dripped condensate water can fall into the water receiving tray 31 and then is discharged outwards, so that the condensate water can be prevented from dripping onto other parts in the indoor machine shell 11, particularly the condensate water can be prevented from dripping onto related electric parts, and the phenomena of short circuit or electric leakage and the like can be avoided.

In one embodiment, the air conditioner is an integral air conditioner, which further comprises a chassis 13, an outer machine casing 12, a compressor 70 and an outdoor heat exchanger 80; the chassis 13 includes a first disk section 131 and a second disk section 132 (see fig. 9) connected to each other, the inner machine casing 11 is disposed in the first disk section 131, the outer machine casing 12 is disposed in the second disk section 132, the outer machine casing 12 is connected to the inner machine casing 11, the compressor 70 is disposed in the inner machine casing 11 and located below the water pan 31, and the outdoor heat exchanger 80 is disposed in the outer machine casing 12.

It should be noted that the "inner machine casing 11" and the "outer machine casing 12" in the embodiment of the present invention do not limit the installation positions of the inner machine casing 11 and the outer machine casing 12, and the integrated air conditioner may be installed in a room as a whole, in which case, the inner machine casing 11 and the outer machine casing 12 are both installed in the room. It is also possible to dispose the inner machine casing 11 indoors and to extend the outer machine casing 12 at least partially outdoors. In order to allow the outer cabinet 12 to protrude outdoors, a mounting hole is generally provided in the wall body so that the outer cabinet 12 can protrude outdoors from the mounting hole, in which case the portion of the space (mounting hole) between the inner surface of the wall body and the outer surface of the wall body can be regarded as an outdoor space, that is, the space inside the inner surface of the wall body can be regarded as an indoor space, and the space outside the inner surface of the wall body can be regarded as an outdoor space.

It should be noted that the term "wall" is used herein in a broad sense, that is, the "wall" may be a wall of a common building (e.g., a wall built with building bricks), a wall panel of a portable house, or a side panel of a container house. That is, the unitary air conditioner may be used in a portable room or a container room, and may also be used in a commercial room.

Further, by disposing the compressor 70 inside the inner machine case 11, in use, the compressor 70 and the inner machine case 11 can be placed indoors so that the outer machine case 12 is extended outdoors. The overall weight of the outer machine casing 12 is reduced, so that the pressure of the outer machine casing 12 on the support frame can be reduced when the outer machine casing 12 is installed on a floor above the second floor of a house. For example, when the integral air conditioner is used in a portable house or a container house having two or more layers, the pressure on the support frame can be reduced by installing the outer casing 12 outdoors, and when the outer casing 12 is connected to the inner casing 11, the outer casing 12 can be supported without the support frame, which is convenient for use in the portable house or the container house. Of course, in other embodiments, the compressor 70 may be disposed within the outer casing 12.

It should be noted that, in the present embodiment, the air conditioner applied to the related structure between the indoor side heat exchanger 20 and the water pan 31 is an integral air conditioner; however, the design is not limited thereto, and in other embodiments, the air conditioner applied to the related structure between the indoor side heat exchanger 20 and the water pan 31 may also be a split type air conditioner, such as but not limited to a split type cabinet air conditioner, a split type hanging air conditioner, etc.

It can be understood that, in this embodiment, the first heat exchange section 21 and the second heat exchange section 22 are disposed at an angle, and form a V-shaped structure with an upward opening, and a projection of a lower end of the V-shaped structure on the water-receiving tray 31 is located in the water-receiving tray 31, so that condensed water formed on the first heat exchange section 21 and the second heat exchange section 22 can both drip into the water-receiving tray 31. In addition, the V-shaped structure formed by the first heat exchange section 21 and the second heat exchange section 22 is beneficial to increasing the heat exchange area of the indoor side heat exchanger 20, improving the heat exchange capability of the indoor side heat exchanger 20 and improving the energy efficiency of the air conditioner.

It can be understood that part of the condensed water formed on the second heat exchange section 22 flows downwards along the first support frame 41. According to the technical scheme of the embodiment, the lower end of the first support frame 41 and the first side wall 311 are arranged at intervals, so that the part of the condensed water flowing downwards along the first support frame 41 can be prevented from flowing to the outer side of the first side wall 311, and the condensed water can be ensured to flow into the water pan 31.

In an embodiment, the water-receiving tray 31 further has a second side wall 312 adjacent to the first side wall 311, and a second space is provided between the lower end of the first support frame 41 and the second side wall 312 to prevent the condensed water from flowing to the outside of the second side wall 312, thereby further ensuring that the condensed water can flow into the water-receiving tray 31.

In one embodiment, the water tray 31 further has a third side wall 313 parallel to and spaced apart from the first side wall 311; the air conditioner further comprises a second support frame 42 which is arranged in a plate shape, the lower end of the second support frame 42 is connected with the water pan 31, and the upper end of the second support frame is connected to the lower side of the upper end of the first heat exchange section 21. It can be understood that the addition of the second support frame 42 can further support the indoor side heat exchanger 20, thereby further improving the installation stability of the indoor side heat exchanger 20; on the other hand, the second support frame 42 is in a plate shape, and can be used for assisting in forming an internal air duct of the air conditioner, reducing air leakage, and improving the heat exchange efficiency of the indoor side heat exchanger 20.

Optionally, the upper end of the second supporting frame 42 is provided with an air leakage prevention flange 421, and the air leakage prevention flange 421 is attached to the lower side of the upper end of the first heat exchange section 21.

In one embodiment, a third space is provided between the lower end of the second supporting frame 42 and the third side wall 313. It will be appreciated that the outer surface of the second support shelf 42 may be formed with condensed water, which may flow down along the second support shelf 42. According to the technical scheme of the embodiment, the lower end of the second support frame 42 and the third side wall 313 are arranged at intervals, so that part of the condensed water flowing downwards along the second support frame 42 can be prevented from flowing to the outer side of the third side wall 313, and the condensed water can be ensured to flow into the water pan 31. Further optionally, the third spacing L2 is greater than or equal to 3 millimeters; it is understood that if the third interval L2 is too small, when the falling condensed water droplets are large, the large droplets may partially cross the third interval and flow to the outside of the third side wall 313; in this embodiment, the third interval L2 is not less than 3 mm to ensure that the third interval is large to prevent the condensed water from flowing to the outside of the third side wall 313.

In the former embodiment, since the outer surface of the second supporting frame 42 may form condensed water, the third space needs to be provided to allow the surface condensed water to flow to the outside of the third sidewall 313. However, the design is not limited thereto, in other embodiments, an insulating layer may be further disposed on a surface of the second supporting frame 42 facing the third sidewall 313 to prevent the outer surface of the second supporting frame 42 from forming condensed water, and if so designed, the third space may not be disposed. Of course, in other embodiments, the third space may be provided while the surface of the second supporting frame 42 facing the third side wall 313 is covered with an insulating layer, which is not limited in the present invention.

Optionally, the heat insulation layer on the second support frame 42 is set as a heat insulation sponge layer; the heat-insulating sponge has a good heat-insulating effect and also has the advantage of low cost. However, the design is not limited thereto, and in other embodiments, the insulation layer on the second supporting frame 42 may also be, but not limited to, a flocking layer or an insulation cloth layer. Optionally, the insulating layer on the second support frame 42 is adhered to the outer surface of the second support frame 42; the bonding method is simple and easy to operate, and the structure of the second support frame 42 can be simplified without forming an additional structure for installing the insulation layer on the second support frame 42.

In an embodiment, the indoor heat exchanger 20 further includes a third heat exchange section 23 extending in an up-down direction, and a lower end of the third heat exchange section 23 is connected to an upper end of the second heat exchange section 22; therefore, the heat exchange area of the indoor side heat exchanger 20 is further increased, the heat exchange capacity of the indoor side heat exchanger 20 is improved, and the energy efficiency of the air conditioner is improved. In this embodiment, optionally, the heat exchanger further includes a connecting side plate 24, where the connecting side plate 24 includes a first connecting section 241, a second connecting section 242, and a third connecting section 243 that are connected in sequence, the first connecting section 241 is connected with the first heat exchange section 21, the second connecting section 242 is connected with the second heat exchange section 22, and the third connecting section 243 is connected with the third heat exchange section 23, so that the heat exchanger is connected as a whole, so as to be integrally installed, and thus, the installation efficiency is improved. It should be noted that, in this embodiment, the third heat exchange section 23 may extend along the vertical direction, or may be slightly inclined compared to the vertical direction, and the present invention is not limited thereto.

Optionally, the projection of the lower end of the third heat exchange section 23 on the water pan 31 is located in the water pan 31. It will be appreciated that the third heat exchange stage 23 will form condensed water which will flow down along the third heat exchange stage 23 itself. Most of the condensed water flowing down from the third heat exchange section 23 will continue to flow down along the second heat exchange section 22 and finally drop into the water pan 31 from the lower end of the V-shaped structure, but some of the condensed water may also directly drop down from the lower end of the third heat exchange section 23. In the technical scheme of this embodiment, the projection of the lower end of the third heat exchange section 23 on the water collector 31 is also located in the water collector 31, so that part of the condensed water directly dropping downward from the lower end of the third heat exchange section 23 does not drop outside the water collector 31, and it is ensured that the water collector 31 can collect the part of the condensed water.

It will be appreciated that the first side wall 311 is not only parallel to and horizontally adjacent the upper end of the second heat exchange section 22, but also parallel to and horizontally adjacent the lower end of the third heat exchange section 23. Optionally, the upper edge of the first side wall 311 is provided with a water retaining flange 314 extending outward, and a projection of the lower end of the third heat exchange section 23 on the water collector 31 is located in the water retaining flange 314, so that part of the condensed water dropping downward directly from the lower end of the third heat exchange section 23 can flow back into the water collector 31 under the limiting action of the water retaining flange 314. In addition, the water retaining flange 314 is normally spaced from the lower end of the first support frame 41, so that part of the condensed water flowing downwards along the first support frame 41 can be prevented from flowing to the outer side of the first side wall 311, and the condensed water can be ensured to flow into the water pan 31; optionally, an interval L1 between the lower end of the first support frame 41 and the water baffle flange 314 is greater than or equal to 4 mm; it can be understood that if the interval L1 between the lower end of the first support frame 41 and the water-retaining flange 314 is too small, when the size of the flowing condensed water drops is large, the large water drops may partially cross the interval and flow outside the water-retaining flange 314; in this embodiment, the distance L1 is not less than 4 mm, so as to ensure that the distance L1 is large, and prevent the condensed water from flowing to the outside of the water-blocking flange 314. It should be noted that, for the technical solution with the water retaining flange 314, the first interval may not be provided; of course, the water blocking flange 314 and the first space may be provided at the same time, which is not limited in the present invention. Further optionally, the water retaining flange 314 includes a first water retaining section extending upward and obliquely outward from the upper edge of the first side wall 311, and a second water retaining section extending upward from the first water retaining section; it can be understood that the second water retaining section is arranged to facilitate heightening of the water retaining flange 314, so that condensed water is prevented from splashing out of the water receiving tray 31, and the first water retaining section arranged obliquely is arranged to facilitate guiding the condensed water back into the water receiving tray 31.
