The invention provides an air conditioner integrated machine.

In an embodiment of the present invention, as shown in fig. 1 to 5, the air conditioner integrated machine includes:

a housing having a first cavity 10 and a second cavity 20, an air inlet 101 and an air outlet 102 respectively communicating with the first cavity 10 and the indoor space, and an air outlet 201 communicating with the second cavity 20 and the outdoor space;

the first heat exchanger 30 is arranged in the first cavity 10, the first heat exchanger 30 comprises two heat exchange parts 31 with adjacent top ends and included angles at bottom ends, the first heat exchanger 30 divides the first cavity 10 into an upper cavity and a lower cavity, the air inlet 101 is communicated with one cavity, and the air outlet 102 is communicated with the other cavity; and, a step of, in the first embodiment,

a second heat exchanger is located within the second cavity 20.

In the embodiment of the present invention, the first cavity 10 and the second cavity 20 are preferably arranged in the horizontal direction. The bottom ends of the two heat exchanging parts 31 are preferably located on the bottom wall of the first cavity 10, and the bottom wall of the first cavity 10 is used for supporting the first heat exchanger 30. Since the first heat exchanger 30 is in an inverted V shape, the bottom ends of the two heat exchanging portions 31 are separated and the top ends thereof are close, so that the first heat exchanger 30 can be stably erected on the bottom wall of the first cavity 10.

In order to enable the air flowing into the first cavity 10 from the air inlet 101 to flow through the first heat exchanger 30 for heat exchange, the side edge of the first heat exchanger 30 is preferably abutted against the inner side wall of the first cavity 10, so that the air is prevented or reduced from flowing through a gap between the side edge of the first heat exchanger 30 and the inner side wall of the first cavity 10.

The first heat exchanger 30 divides the first cavity 10 into an upper cavity and a lower cavity, the air inlet 101 can be communicated with the lower cavity, and the air outlet 102 is communicated with the upper cavity, so that the first cavity 10 is fed with air from below and discharged with air from above; of course, the air inlet 101 may also be in communication with the upper cavity, and the air outlet 102 may be in communication with the lower cavity.

In general, the air conditioning unit is placed outdoors, the air of the air outlet 201 is directly discharged outdoors, and the air inlet 101 and the air outlet 102 may be connected indoors by a pipe, or may be perforated on a wall or a glass window, so that the air inlet 101 and the air outlet 102 are communicated with the room through the holes. Indoor air enters the first cavity 10 from the air inlet 101, and after heat exchange by the first heat exchanger 30, is blown into the room from the air outlet 102, so as to meet indoor refrigeration or heating requirements.

In the invention, the first heat exchanger 30 is arranged in a V shape, and compared with a straight plate shape, the structure is more compact, has a larger heat exchange area, and is beneficial to reducing the volume of the whole machine. Since the first heat exchanger 30 is located on the bottom wall of the first cavity 10, there is no need to provide an additional support structure on the housing for supporting the first heat exchanger 30 to prevent the first heat exchanger 30 from falling, so that the structure of the housing can be simplified.

In the embodiment of the present invention, the included angle between the two heat exchanging portions 31 is 25 ° -35 °. Specifically, the included angle between the two heat exchanging portions 31 may be 25 ° or 35 °, preferably 30 °, so that the air conditioner integrated machine is not only prevented from being too long due to too large included angle, but also the heat exchanging area is prevented from being too small due to too small included angle.

In order to make the contact between the first heat exchanger 30 and the inner side wall of the first cavity 10 better, in one embodiment, the inner side wall of the first cavity 10 is provided with a lapping protrusion, and the lapping protrusion extends along the side edge of the heat exchanging portion 31, and the inner sides of the two heat exchanging portions 31 lean against the lapping protrusion. The inner sides of the two heat exchanging portions 31 refer to the two sides of the two heat exchanging portions 31 facing each other. By arranging the overlap joint convex part, the first heat exchanger 30 is overlapped with the overlap joint convex part, so that the generation of a space between the first heat exchanger 30 and the inner side wall of the first cavity 10 is avoided, and air can flow out after heat exchange of the first heat exchanger 30. Meanwhile, the lap joint convex part can also better support the first heat exchanger 30, so that the first heat exchanger 30 leans against the lap joint convex part, the two heat exchange parts 31 are prevented from being respectively close, and the two heat exchange parts 31 can also be prevented from sliding down.

The above-mentioned overlap protrusion may be a protrusion provided on the inner side surface of the housing, but in other embodiments, the overlap protrusion may be formed in other forms. For example, in one embodiment, referring to fig. 6 to 8, the housing includes a first housing 40 and a second housing 50 disposed above and below each other, and the first housing 40 and the second housing 50 are connected to each other to form the first cavity 10.

In this embodiment, the overlapping flanges 521 may extend inwardly from the side edges of the overlapping side panels 52, may extend outwardly, or may extend both inwardly and outwardly.

The air conditioner all-in-one machine may further include a fixing strip, where the fixing strip is located at a side edge of the first heat exchanger 30 and is used for the heat exchange tube of the first heat exchanger 30 to pass through, and the fixing strip is fixed with the lap joint convex part by a screw, so that the first heat exchanger 30 can be fixed on the lap joint convex part.

In the embodiment of the present invention, the first housing 40 includes a top wall 41 opposite to the bottom plate 51, and a peripheral wall 42 surrounding the periphery of the top wall 41, wherein a notch 421 is provided at the bottom end of the peripheral wall 42 and corresponds to each overlapping side plate 52, and the two notches 421 are tapered from bottom to top; the overlapping side plate 52 is inserted into the notch 421 to cover the notch 421, and the bottom end of the peripheral wall 42 is connected to the chassis 51, so as to form the first cavity 10. Preferably, a first mounting flange 422 is provided at a position of the peripheral wall 42 where the notch 421 is provided, and the first mounting flange 422 is connected to a lap flange 521 on the lap side plate 52. Meanwhile, a second mounting flange 423 is provided at the bottom end of the peripheral wall 42, and the peripheral wall 42 is fixed to the chassis 51 by the second mounting flange 423. By fixing in the form of a flange, the contact area can be increased, facilitating the connection of the first housing 40 and the second housing 50.

In the present invention, the first heat exchanger 30 may be mounted on the second housing 50 and then the first housing 40 may be mounted by dividing the housing forming the first cavity 10 into the first housing 40 and the second housing 50, so that the first heat exchanger 30 may be mounted conveniently.

In other embodiments, the peripheral wall 42 of the first housing 40 is not provided with the notch 421, and the entire peripheral wall 42 is covered on the second housing 50 to cover the overlapping side plate 52.

In the embodiment of the present invention, the air inlet 101 is disposed on one of the overlapping side plates 52. Of course, the air inlet 101 may also be disposed on the peripheral wall 42 and near the bottom end. The air outlet 102 may be disposed on a top surface of the first cavity 10, or may be disposed on a side surface of the first cavity 10.

In an embodiment, the top wall 41 is provided with a communication port 411, and preferably, the communication port 411 is disposed corresponding to a connection position of the two heat exchange portions 31. The air conditioner integrated machine further comprises a centrifugal fan 60, the centrifugal fan 60 is located at the outer side of the top wall 41, the air inlet side of the centrifugal fan 60 is arranged corresponding to the communication port 411, and the air outlet side of the centrifugal fan 60 forms the air outlet 102. Specifically, the centrifugal fan 60 includes a centrifugal wind wheel and a centrifugal volute, the centrifugal volute is mounted on the outer surface of the top wall 41, specifically, a screwing or clamping manner may be adopted, and the centrifugal fan 60 is located in the centrifugal volute and is disposed opposite to the communication port 411. The air outlet side of the centrifugal volute and the air inlet 101 are preferably located on the same side of the air conditioner integrated machine, and when the air conditioner integrated machine is located outdoors, the air outlet side of the centrifugal volute and the air inlet 101 are located on one side, facing indoors, of the air conditioner integrated machine, so that the air outlet side of the centrifugal volute and the air inlet 101 are conveniently communicated with the indoor space.

In order to form a better air outlet effect, preferably, the air outlet 102 of the centrifugal volute is gradually expanded along the air outlet direction, so that the air outlet area can be better enlarged, and a wider air supply range is ensured.

Referring to fig. 6 again, since the air conditioner unit generates condensed water on the first heat exchanger 30 when cooling, the condensed water drops on the bottom plate 51, in order to avoid the bottom end of the first heat exchanger 30 from being immersed in the condensed water and to make the condensed water better accumulate on the bottom plate 51, the bottom wall of the first cavity 10 is provided with a supporting boss 511 on the bottom plate 51 and corresponding to the bottom ends of the two heat exchange portions 31, and each heat exchange portion 31 is disposed on the top surface of one supporting boss 511. Preferably, the support boss 511 abuts a side wall of the chassis 51. For discharging the condensed water, a drain 512 is provided in the bottom plate 51. Preferably, the drain opening 512 is provided on a side wall of the chassis 51 and is provided through the support boss 511 adjacent to the side wall. By providing the support boss 511 to support the heat exchanging part 31, condensed water flows to the support boss 511 along the heat exchanging part 31 and is accumulated on the bottom surface of the bottom plate 51, and is discharged from the water discharge port 512, thereby avoiding the first heat exchanger 30 from blocking the discharge of condensed water.

In order to make the condensed water flow down from the support boss 511 better, the top surface of the support boss 511 is inclined downward from the outside to the inside of the first cavity 10, thereby forming a better guiding effect.
