The invention provides a wall-mounted air conditioner integrated machine.
In the embodiment of the present invention, as shown in fig. 1 to 4, the wall-mounted air conditioner integrated machine includes a housing, and a cross flow fan 200, an axial flow fan 300, a first heat exchanger 400 and a second heat exchanger 500 disposed in the housing; the casing has a rear wall 110 for wall-mounting, a first air inlet 101 is provided on the casing corresponding to the air inlet side of the through-flow fan 200, a first air outlet 102 is provided corresponding to the air outlet side of the through-flow fan 200, a second air inlet 103 is provided corresponding to the air inlet side of the axial-flow fan 300, and a second air outlet 104 is provided corresponding to the air outlet side of the axial-flow fan 300; the second air outlet 104 is communicated with the outside; the first heat exchanger 400 is arranged between the first air inlet 101 and the air inlet side of the cross flow fan 200; the second heat exchanger 500 is disposed between the second air inlet 103 and the air inlet side of the axial flow fan 300.
In the embodiment of the present invention, the cross flow fan 200 and the axial flow fan 300 may be distributed in a horizontal direction or may be distributed in a vertical direction. The wall-mounted air conditioner is installed indoors, for example, in a kitchen, and the axial flow fan 300 sends out the air after heat exchange with the second heat exchanger 500 outdoors through the second air outlet 104. Specifically, the second air outlet 104 may be located on the rear wall 110 of the housing, so that an air outlet may be formed on an indoor wall or window glass at a position corresponding to the second air outlet 104, so that the second air outlet 104 is directly communicated with the air outlet. The second air outlet 104 may also be located on the top surface, the bottom surface or the side surface of the casing, and is connected to the air outlet by a hose or an elbow arranged on the second air outlet 104, so that the air outlet may be arranged at any position of an indoor wall or window glass, so that the installation position of the wall-mounted air conditioner is not limited.
Specifically, the indoor air enters the air inlet side of the cross flow fan 200 from the first air inlet 101 under the action of the cross flow fan 200, and after exchanging heat with the first heat exchanger 400, is blown back into the room from the first air outlet 102 by the cross flow fan 200. Meanwhile, the indoor air enters the air inlet side of the axial flow fan 300 from the second air inlet 103 under the action of the axial flow fan 300, and is sent out of the room from the second air outlet 104 by the axial flow fan 300 after exchanging heat with the second heat exchanger 500.
In the invention, the wall-mounted air conditioner is arranged on the wall body through the rear wall 110, so that the occupation of the object placing space can be reduced, and the placing of other objects in the room is convenient. Meanwhile, by adopting the mode that the axial flow fan 300 sends out the indoor air after the heat exchange of the second heat exchanger 500 outdoors, the air supply distance is far because the air supply pressure of the axial flow fan 300 is large, and the axial flow fan can effectively send out the indoor air after the heat exchange of the second heat exchanger 500 to a position far outdoors, thereby avoiding the influence on the heat exchange of the second heat exchanger 500 caused by the fact that the indoor air after the heat exchange of the second heat exchanger 500 is accumulated at the air supply opening on the wall body. In addition, by adopting the mode of the cross-flow fan 200, the noise is low, the comfort is good and the like.
In the embodiment of the present invention, the wall-mounted air conditioner integrated machine further includes a compressor assembly 600 disposed in the housing, and the cross flow fan 200, the axial flow fan 300, and the compressor assembly 600 may be disposed in a horizontal direction or in a vertical direction. For example, in one embodiment, the cross flow fan 200 and the axial flow fan 300 are separately disposed at both ends of the housing in the horizontal direction, so as to leave a space for installing the compressor assembly 600 between the cross flow fan 200 and the axial flow fan 300. By installing the compressor assembly 600 between the cross flow fan 200 and the axial flow fan 300, the distance between the cross flow fan 200 and the axial flow fan 300 is long, and the air blown out through the first air outlet 102 can be effectively prevented from flowing back to the second air inlet 103, thereby avoiding energy loss. Preferably, in this embodiment, the axial direction of the cross flow fan 200 extends in the left-right direction, and the axial direction of the axial flow fan 300 extends in the front-rear direction.
Further, the housing further has a front wall 120 opposite to the rear wall 110, and a plurality of side walls 130 connecting the rear wall 110 and the front wall 120, the first air outlet 102 and the first air inlet 101 are both disposed on the front wall 120, and the first air outlet 102 is located below the first air inlet 101. In this embodiment, the first air inlet 101 and the first air outlet 102 are disposed on the front wall 120, and the front wall 120 is not shielded by a wall body, so that the air inlet of the first air inlet 101 and the air outlet of the first air outlet 102 are not obstructed, and the installation position of the wall-mounted air conditioner is not limited. Meanwhile, because the first air outlet 102 is located below the first air inlet 101, when the wall-mounted air conditioner integrated machine is used for indoor refrigeration, the cold air blown out through the first air outlet 102 sinks, so that the phenomenon that the cold air directly moves into the first air inlet 101 can be reduced, and the energy is reasonably utilized. Particularly, when the wall-mounted air conditioner is used as a kitchen air conditioner, only cooling is often needed in the kitchen due to high kitchen temperature, and energy can be saved by arranging the first air outlet 102 below the first air inlet 101.
The front wall 120 includes a vertical wall 121 and an inclined wall 122 connected to a lower end of the vertical wall 121, the inclined wall 122 being gradually inclined from top to bottom in a direction approaching the rear wall 110; the first air outlet 102 is located on the inclined wall 122, and the first air inlet 101 is located on the vertical wall 121. In this embodiment, by providing the inclined wall 122, the air blown out through the first air outlet 102 may be blown out obliquely downward, so that the air supply range is wider, and the cooled air or the hot air after heat exchange may be effectively sent to the indoor lower side, thereby improving the user experience.
Referring to fig. 5 in combination, since the through-flow fan 200 is radially air-in and radially air-out, in order to guide the air blown by the through-flow fan 200 to the front side of the housing, the volute tongue 210 and the volute 220 of the through-flow fan 200 both extend forward, specifically, the volute tongue 210 of the through-flow fan 200 extends obliquely forward from the front side of the through-flow fan 200 to abut against the inner side of the inclined wall 122; the volute 220 of the cross flow fan 200 extends obliquely forward from the rear side of the cross flow fan 200 to abut against the inner side of the inclined wall 122; the first air outlet 102 is located between the volute tongue 210 and the volute 220 of the cross-flow fan 200. Because the volute tongue 210 and the volute 220 are propped against the inclined wall 122, air blown out from the air outlet of the cross-flow fan 200 is prevented from diffusing to the periphery, so that the air can be intensively sent out from the first air outlet 102, the loss of air energy is reduced, the air supply pressure of the cross-flow fan 200 is ensured, the air supply distance is further, and the temperature of each part in a room is more uniform.
The first heat exchanger 400 is at least partially arranged around the cross flow fan 200, and the heat exchange area of the first heat exchanger 400 is larger, so that air can be subjected to heat exchange with the first heat exchanger 400 before entering the air channel of the cross flow fan 200, the heat exchange efficiency is improved, and energy sources can be reasonably utilized. Preferably, the first heat exchanger 400 includes a first section 410, a second section 420 and a third section 430 connected in sequence, wherein the first section 410 is disposed opposite to the first air inlet 101 on the front wall 120; the second section 420 is inclined backward gradually from the top of the first section 410 upwards; the third section 430 is disposed gradually and obliquely downward from the top end of the second section 420.
In an embodiment, the front wall 120 is provided with the second air inlet 103 at a position corresponding to the air inlet side of the axial flow fan 300, and the rear wall 110 is provided with the second air outlet 104 at a position corresponding to the air outlet side of the axial flow fan 300. By arranging the second air inlet 103 on the front wall 120, the front wall 120 is not shielded by a wall body, so that the air inlet of the second air inlet 103 is not blocked, and the installation position of the wall-mounted air conditioner is not limited. Meanwhile, since the second air outlet 104 is disposed on the rear wall 110, when the wall-mounted air conditioner is installed, an air outlet can be directly disposed at a position of the wall corresponding to the second air outlet 104, so that air blown out from the second air outlet 104 can be blown out to the outside directly from the air outlet without additional communication pipes or other components for air guiding, thereby simplifying the structure and reducing the installation steps. Of course, in other embodiments, the second air outlet 104 may be disposed at other locations of the housing than the rear wall 110, such as the front wall 120 or the side wall 130. When the second air outlet 104 is disposed on the front wall 120 or the side wall 130, in order to ensure that the air blown out through the second air outlet 104 is smoothly discharged to the outside, an exhaust pipe (not shown) is further disposed on the second air outlet 104, one end of the exhaust pipe is communicated with the second air outlet 104, and the other end of the exhaust pipe extends into the air outlet on the wall body to be communicated with the outside. Specifically, the exhaust pipe may be a hose or be arranged in a bent shape, so as to adapt to the installation of the second air outlet 104 and the air supply outlet at different positions. In addition, when wall-hanging air conditioner all-in-one is installed in the kitchen, owing to be equipped with oily tobacco pipe and total flue in the kitchen, total flue and outdoor intercommunication, consequently, can be in the other end of blast pipe sets up the three-way valve, the three-way valve includes first end, second end and third end, wherein, first end with the other end intercommunication of blast pipe, the second end with oily fume pipe intercommunication, the third end with total flue intercommunication, so, the three-way valve will the blast pipe with oily fume pipe inserts respectively total flue to the installation has been simplified.
In the embodiment of the present invention, in order to increase the heat exchange efficiency and increase the air intake, the number of the second air inlets 103 is plural, wherein one second air inlet 103 is disposed on the front wall 120, and the other second air inlets 103 are disposed on the side wall 130 adjacent to the air intake side of the axial flow fan 300, for example, at least one second air inlet 103 is disposed on the side wall 130 adjacent to the air intake side of the axial flow fan 300. Specifically, the plurality of side walls 130 include a left side wall facing to the left side and a right side wall facing to the right side, the cross flow fan 200 is disposed close to the left side wall, the axial flow fan 300 is disposed close to the right side wall, and the second air inlet 103 is disposed at a position of the right side wall adjacent to the air inlet side of the axial flow fan 300. Of course, the second air inlet 103 may be disposed on the other side wall 130.
The second heat exchanger 500 includes a plurality of main heat exchange sections, each of the main heat exchange sections is disposed corresponding to one of the second air inlets 103, so that air entering through any one of the second air inlets 103 can fully exchange heat with the second heat exchanger 500, thereby improving heat exchange efficiency. In an embodiment, the front wall 120 and the right side wall are each provided with the second air inlet 103, so that the second heat exchanger 500 correspondingly includes two main heat exchange sections and is in an L-shape.
Further, as shown in fig. 3, a baffle 710 is disposed between the axial flow fan 300 and the cross flow fan 200, and the second heat exchanger 500 is mounted on the baffle 710 and is disposed around the air intake side of the axial flow fan 300 together with the baffle 710. Specifically, a mounting plate 720 is disposed in the casing, the compressor assembly 600, the axial flow fan 300, the second heat exchanger 500 and the baffle 710 are all mounted on the mounting plate 720, the baffle 710 is preferably disposed between the compressor assembly 600 and the axial flow fan 300, as shown in fig. 7, a fixing hole 711 for passing through a heat exchange tube on the second heat exchanger 500 is disposed at the front end of the baffle 710, so as to fix the second heat exchanger 500, and the baffle 710 is connected with the second heat exchanger 500 to form a U-shape. When the air enters the housing from the second air inlet 103 and exchanges heat with the two heat exchangers 500, most of the air can enter the air channel of the axial flow fan 300, and a small part of the air diffuses all around, so that by arranging the baffle 710, the small part of the air can be prevented from flowing towards one side of the through flow fan 200, and meanwhile, the air entering from the first air inlet 101 can be prevented from flowing to one side of the axial flow fan 300, thereby avoiding the interference of the air between the first air inlet 101 and the second air inlet 103.
