[0040] Please refer to the attached Figure 1 The present invention provides a vertical fresh air air conditioning device, the vertical fresh air air conditioning device comprising:

[0041] The housing 10 includes an air inlet duct 11, an air outlet duct 12, a return air duct 13, and an air outlet duct 14. The air inlet duct 11 and the air outlet duct 12 are both used to communicate with the outside, and the return air duct 13 is used to communicate with the inside of the room.

[0042] The temperature regulating assembly is arranged in the housing 10, including a compressor 310, a four-way valve 320, a condenser 330 and an evaporator 340 which are sequentially connected through a refrigerant pipeline; the condenser 330 is arranged in the exhaust air duct 12, and the evaporator 340 is arranged in the outlet air duct 14;

[0043] A heat exchange core 200 is arranged in the shell 10, and an indoor air duct and an outdoor air duct are formed on the heat exchange core 200. The air inlet end of the indoor air duct faces the return air duct 13, and the air outlet end of the indoor air duct faces the exhaust air duct 12; the air inlet end of the outdoor air duct faces the air inlet duct 11, and the air outlet end of the outdoor air duct faces the air outlet duct 14.

[0044] Among them, the air inlet duct 11 is connected to the outdoors to introduce fresh air from the outdoors, the air outlet duct 14 is connected to the indoors to supply conditioned air into the indoors, the return air duct 13 is connected to the indoors to recycle a portion of the indoor air for air circulation, and the exhaust duct 12 is connected to the outdoors to exhaust turbid indoor air to the outdoors.

[0045] Among them, the specific structure and function of the temperature adjustment component can refer to the existing air conditioning temperature adjustment structure. For example, when in the indoor cooling mode, the compressor 310 compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser 330 of the exhaust duct 12 to dissipate heat and become a liquid refrigerant at normal temperature and high pressure. The liquid refrigerant is then sent to the evaporator 340 of the outlet duct 14 to absorb heat, so that the air supplied to the room is cold air.

[0046] Among them, the heat exchange core 200 serves as an intermediary device for each air duct, and the outdoor air entering the room and the indoor air being discharged to the outdoor all pass through the heat exchange core 200. The heat exchange core 200 is a prior art, and its specific structure is not introduced in detail here. The heat exchange core 200 is generally provided with two independent air ducts, which are used to transport cold air and hot air respectively. The heat exchange core 200 recycles the coldness or heat of the indoor air to pre-cool or pre-heat the fresh air. For example, when in the indoor cooling mode, the indoor cold air enters the heat exchange core 200 through the return air duct 13 to pre-cool the outdoor fresh air; when in the indoor heating mode, the indoor hot air enters the heat exchange core 200 through the return air duct 13 to pre-heat the outdoor fresh air, thereby achieving the purpose of saving energy.

[0047] The return air duct 13 and the outlet air duct 14 may not be separated, so that part of the indoor air can be internally circulated, thereby achieving the purpose of saving electricity.

[0048] In the scheme of the present application, since the vertical fresh air air conditioning device includes a housing 10, a temperature adjustment component, a heat exchange core and an air outlet component, the housing 10 is formed with an air inlet duct 11, an exhaust duct 12, a return duct 13 and an air outlet duct 14 which are independent of each other, wherein the air inlet duct 11 is connected to the outside to introduce fresh air from the outside, the air outlet duct 14 is connected to the room to supply the conditioned air into the room, the return duct 13 is connected to the room to recycle a part of the indoor air for air circulation, and the exhaust duct 12 is connected to the outside to discharge the turbid indoor air to the outside. The temperature adjustment component is arranged in the housing 10 to realize air cooling and heating, wherein the condenser 330 is arranged in the exhaust duct 12 to perform heat exchange with the air to be discharged to the outside, and the evaporator 340 is arranged in the exhaust duct 14 to perform heat exchange with the air to be supplied to the room. The heat exchange core 200 is used as an intermediary device for each air duct, and the outdoor air enters the room and the indoor air is discharged to the outside through the heat exchange core. The heat exchange core 200 is used to recover the cold or heat of the indoor air to pre-cool or pre-heat the fresh air. The present application combines the fresh air with the air conditioning technology, so that the fresh air can be introduced from the outside, thereby improving the indoor air quality. The heat exchange core 200 serves as an intermediary device for each air duct, and can pre-cool or pre-heat the fresh air at the same time, saving energy consumption and improving the energy efficiency ratio of the equipment.

[0049] Please refer to the attached Figure 2 To Attachment Figure 4 As a specific embodiment of the present invention, the housing 10 includes a lower wind box 100 and an upper wind box 101 disposed on the top of the lower wind box 100. An air outlet duct 14 is formed in the upper wind box 101. An air outlet connected to the air outlet duct 14 is formed on the side wall of the upper wind box 101. The bottom of the upper wind box 101 is connected to the top of the lower wind box 100. The evaporator is disposed in the upper wind box 101. In this embodiment, in order to better discharge air, an upper wind box 101 for discharging air is separately provided, and various air outlet components can be disposed in the upper wind box 101. Furthermore, the upper wind box 101 is rotatably disposed on the lower wind box 100, so that air can be discharged while rotating.

[0050] Specifically, the lower air box 100 includes an upper top plate 110 and a lower bottom plate 120 which are arranged in parallel and opposite to each other, and a return air plate 130, a wind shield plate 140, a wind partition plate 150, a left plate 160 and a right plate 170 which are arranged between the upper top plate 110 and the lower bottom plate 120; an air outlet 111 is formed on the upper top plate 110, and a return air outlet 131 is formed on the return air plate 130; the wind shield plate 140 is arranged opposite to the return air plate 130, and an exhaust air outlet 141 and an air inlet 142 are formed on the wind shield plate 140; wherein, the air inlet end of the indoor air duct faces the return air outlet 131, and the air outlet end of the indoor air duct faces the exhaust air outlet 141; the air inlet end of the outdoor air duct faces the air inlet 142, and the air outlet end of the outdoor air duct faces the air outlet 111;

[0051] The wind partition plate 150 is vertically arranged on the wind shield plate 140, and the exhaust port 141 and the air inlet 142 are respectively located on both sides of the wind partition plate 150; the left side plate 160 and the right side plate 170 are arranged opposite to each other; the upper top plate 110, the lower bottom plate 120, the return air plate 130, the wind shield plate 140, the left side plate 160 and the right side plate 170 enclose a chamber with six walls; the upper top plate 110, the lower bottom plate 120, the wind partition plate 150, and the left side plate 160 enclose an exhaust duct or an air inlet duct; the upper top plate 110, the lower bottom plate 120, the wind partition plate 150, and the right side plate 170 enclose an air inlet duct or an exhaust duct.

[0052] In this embodiment, since the air inlet end of the indoor air duct faces the return air port 131, and the air outlet end of the indoor air duct faces the exhaust port 141, the turbid air in the room can be discharged to the outside from the exhaust port 141 through the indoor air duct of the heat exchange core 200. The air inlet end of the outdoor air duct faces the air inlet 142, and the air outlet end of the outdoor air duct faces the air outlet 111, and the fresh air outside can be transported to the room from the air inlet 142 through the outdoor air duct of the heat exchange core 200. When the outdoor air passes through the heat exchange core 200, the heat or cold of the indoor air will be transferred to the outdoor air, thereby preheating or precooling the outdoor air. In addition, the wind partition 150 is vertically arranged on the wind shield 140, and the exhaust port 141 and the air inlet 142 are respectively located on both sides of the wind partition 150, thereby separating the air inlet duct or the exhaust duct from affecting each other. The fresh air duct structure of the present application can solve the problem of introducing fresh air into air-conditioning equipment, improve indoor air quality and reduce energy consumption.

[0053] As a preferred embodiment of the present invention, the lower air box 100 further includes a first partition 180; one end of the first partition 180 is connected to the top of the heat exchange core 200, and the other end of the first partition 180 is fixed to the junction of the wind shield 140 and the upper top plate 110 to separate the air inlet 142 from the air outlet 141. In this embodiment, in order to reduce the interference between airflows, the first partition 180 can be set to separate the air inlet 142 from the air outlet 141, thereby preventing the indoor wind from entering the air outlet 111.

[0054] As another preferred embodiment of the present invention, the lower air box 100 further includes a second partition 190; one end of the second partition 190 is connected to the bottom of the heat exchange core 200, and the other end of the second partition 190 is fixed to the lower bottom plate 120 to separate the return air port 131 from the air inlet 142. In this embodiment, in order to prevent the indoor air from mixing with the outdoor fresh air, the second partition 190 can be set to separate the return air port 131 from the air inlet 142. The second partition 190 can be vertically set on the lower bottom plate 120.

[0055] As a specific embodiment of the present invention, the wind baffle 150 is arranged in the vertical direction, and the wind baffle 150, the left side plate 160 and the right side plate 170 are parallel to each other. The wind baffle 150 is used to separate the air inlet duct or the air outlet duct, and the wind baffle 150, the left side plate 160 and the right side plate 170 are parallel to each other so that the wind speed at each place in the duct is equal. Preferably, the exhaust port 141 is located obliquely above the air inlet 142. On the one hand, the exhaust port 141 and the air inlet 142 are separated from each other by the wind baffle 150 on the left and right sides, and on the other hand, they are also separated from each other in position up and down, and do not affect each other. Preferably, the return air plate 130 can be an arc-shaped plate, and the left side plate 160, the return air plate 130 and the right side plate 170 form a U-shaped wall panel assembly. Since the return air plate 130 faces the room, setting the return air plate 130 as an arc-shaped plate can prevent the owner from being injured by the edges and corners.

[0056] As a specific embodiment of the present invention, the heat exchange core 200 is a rhombus core. When the heat exchange core 200 is installed, a diagonal line of the rhombus is arranged along the vertical direction. Further, the air inlet end of the indoor air duct is oriented obliquely downward; the air outlet end of the indoor air duct is oriented obliquely upward; the air inlet end of the outdoor air duct is oriented obliquely downward; the air outlet end of the outdoor air duct is oriented obliquely upward, so that the spacing between the air outlets is sufficiently large. Further, the return air outlet 131 is close to the lower base plate 120, and the air outlet 111 is close to the return air plate 130. Further, a plurality of casters 400 can be provided at the bottom of the bellows, and the casters 400 are used to facilitate the movement of the bellows.

[0057] Furthermore, a circle of decorative panels 165 may be provided on the side wall of the lower air box 100. Figure 5 During the specific installation, in order to make the air inlet duct 11 and the exhaust duct 12 communicate with the outside, the wall can be pierced, and the air inlet end of the lower bellows 100 is embedded in the wall. The decorative plate 165 is attached to the wall to indicate the placement position of the lower bellows 100.

[0058] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
