Description

Technical Field

[0001] The present invention relates to the field of air conditioning equipment, in particular to an outdoor unit and an air conditioner having the same. Background Art

[0002] At present, as the requirements for aesthetics and noise in buildings are getting higher and higher, more and more buildings in cities reserve built-in spaces (such as the space under the bay window) for the installation of air conditioner outdoor units (i.e., air conditioner outdoor units). Usually, this type of space has three sides of the building entity and one side is a beautification grille, and the space size is limited.

[0003] If the outdoor unit is a small single-fan outdoor unit, it can be barely installed in the space, but the air outlet is usually facing outward and the air inlet is facing the wall. This outdoor unit installation method makes the air inlet relatively narrow. If it is not installed properly, it is easy to cause partial airflow short circuit in a relatively sealed environment, resulting in poor heat exchange effect. In addition, for household central air conditioners, the outdoor unit that needs to be configured is generally larger and needs an outdoor unit with a double-blade fan. This type of outdoor unit cannot be installed in this type of building at all.

[0004] There is also an air conditioner in the prior art, whose shell includes: a shell body and an escape portion, the escape portion is arranged on the side wall of the shell body, the outer wall of the escape portion protrudes from the outer wall of the shell body, and the inner wall of the escape portion forms a concave structure for escaping the fan blades of the fan. This air conditioner outdoor unit, when the thickness of the fan blades is reduced, increases the diameter of the fan blades and expands the coverage area of ​​the fan blades, thereby ensuring the air supply of the fan and meeting the predetermined heat exchange efficiency requirements of the outdoor unit. The outdoor unit of this structure has air intake at the bottom and air outlet at the top, which is easy to heat (when cooling) or cool (when heating) the building maintenance structure, but increases the building load.

[0005] There is also an embedded air conditioner outdoor unit in the prior art. It can provide an effective installation structure for the installation of an outdoor unit whose capacity is increasing as the air conditioning capacity of the embedded air conditioner increases. The embedded outdoor unit includes a shutter frame fixedly installed on the inner side of a rectangular space formed on the outer wall of a building, which can be divided into an intake area and an exhaust area, each area is provided with a plurality of shutter blades, and air can be inhaled and exhausted through the gaps between the shutter blades; and a shutter frame fixedly installed on the bottom surface of the building inside close to the shutter frame, and one side facing the intake area and the exhaust area on the shutter frame is open and the other side is closed, and a compressor that can compress the gaseous refrigerant provided by the outdoor unit through the refrigerant pipe, an air-cooled condenser that can condense the gaseous refrigerant provided by the compressor, and an outdoor unit housing of a cooling fan that can provide external air to the air-cooled condenser through the intake area and exhaust the air after heat exchange through the exhaust area. This structure fan is installed on the upper part of the heat exchanger. If it is used in a space with a low height, the capacity of the unit will be greatly limited; the directions of its inlet and outlet louvers are consistent, which is not conducive to the organization of airflow.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0031] like Figures 1 to 6 As shown, according to an embodiment of the present invention, the outdoor unit includes an outdoor unit housing 1, the outdoor unit housing 1 has a accommodating cavity, and an air inlet 3 and an air outlet 4 connected to the accommodating cavity are arranged on a first side wall 2 of the outdoor unit housing 1. The outdoor unit also includes a first heat exchanger 7 and a first centrifugal fan 8. The first heat exchanger 7 is arranged in the accommodating cavity corresponding to the air inlet 3, and the first centrifugal fan 8 is arranged in the accommodating cavity corresponding to the first heat exchanger 7. The first centrifugal fan 8 is located on a side of the first heat exchanger 7 away from the air inlet 3. In the axial direction of the first centrifugal fan 8, the first heat exchanger 7 and the first centrifugal fan 8 are located at the same height.

[0032] The air inlet 3 of the outdoor unit allows gas to pass through and enter the outdoor unit housing 1, and the air outlet 4 allows gas to flow out of the outdoor unit housing 1. The first heat exchanger 7 is arranged in the accommodating cavity corresponding to the air inlet 3, and is used to adjust the temperature of the airflow entering through the air inlet 3 and exchange heat with it. Since the first centrifugal fan 8 and the first heat exchanger 7 of the outdoor unit are located at the same height in the axial direction of the first centrifugal fan 8, that is, the outdoor unit is a horizontal outdoor unit, so that the outdoor unit can save space, can adapt to a shorter installation space, and has better adaptability.

[0033] Optionally, the first centrifugal fan 8 is in the form of a centrifugal fan, which can change the direction of air flow so that a good air duct is formed in the outdoor unit casing 1.

[0034] Optionally, in this embodiment, there is a distance between the air outlet 4 and the air inlet 3, a first air guide plate 5 is arranged in the air inlet 3, and a second air guide plate 6 is arranged in the air outlet 4. The first air guide plate 5 makes the air inlet direction of the air inlet 3 away from the air outlet 4, and the second air guide plate 6 makes the air outlet direction of the air outlet 4 away from the air inlet 3.

[0035] The air inlet 3 and the air outlet 4 of the outdoor unit housing 1 of the outdoor unit are both arranged on the first side wall 2. Usually, the air outlet 4 of the outdoor unit faces the outside, while the air inlet 3 faces the external environment at the same time, thereby avoiding the situation where the existing outdoor unit air inlet faces the building wall and causes insufficient air intake. The first air guide plate 5 makes the air inlet direction of the air inlet 3 away from the air outlet 4, and the second air guide plate 6 makes the air outlet direction of the air outlet 4 away from the air inlet 3, thereby avoiding air inlet and air outlet short-flow (short-flow means that the airflow flowing out of the air outlet 4 is directly sucked into the air inlet 3), ensuring the working effect of the outdoor unit.

[0036] In this embodiment, along the direction from the inside to the outside of the accommodating cavity, the first air guide plate 5 is tilted in a first direction, and the second air guide plate 6 is tilted in a second direction opposite to the first direction, so that the second air guide plate 6 of the air outlet 4 and the first air guide plate 5 of the air inlet 3 are arranged in reverse on the horizontal outdoor unit housing 1, optimizing the organization of the airflow in and out and preventing airflow short circuit. Avoiding the straight in and out of the airflow that may be caused by the parallel setting, the airflow near the middle is more likely to short circuit. By reverse arrangement, such as Figure 3 As shown, the airflow comes in at a certain angle from the right and goes out at a certain angle from the left, so the airflow distance is lengthened and the airflow in the middle is not easy to short-circuit.

[0037] like Figure 3 and Figure 4 As shown, in this embodiment, the outdoor unit housing 1 includes, in addition to the first side wall 2, a second side wall, a third side wall 10, a fourth side wall, a top wall and a bottom wall. Among them, the first side wall 2 faces the building grille 24 of the reserved placement space 23 in the building, and the second side wall is separated from the first side wall 2 and parallel to the first side wall 2. The third side wall 10 connects the first end of the first side wall 2 and the second side wall (the first end is the end close to the air inlet 3). The fourth side wall is arranged parallel to and separated from the third side wall 10, and is connected to the second end of the first side wall 2 and the second side wall (the second end is the end close to the air outlet 4). The top wall is arranged above the first side wall 2, and the bottom wall is arranged below the first side wall 2.

[0038] In this embodiment, the first heat exchanger 7 is placed on the bottom wall, and the upper part contacts the top wall, and each contact surface needs to be sealed. The shape of the first heat exchanger 7 can be designed according to actual needs to increase the heat exchange area as much as possible.

[0039] Optionally, the outdoor unit further includes a side air inlet 9, which is disposed on the third side wall 10. By disposing the side air inlet 9, the air inlet area can be increased and the air inlet volume can be increased. The side air inlet 9 can be provided or not provided according to different air inlet volume requirements. Alternatively, the side air inlet 9 can be opened or closed according to different air inlet volume requirements.

[0040] Optionally, if a side air inlet 9 is provided on the outdoor unit housing 1, the outdoor unit further comprises a second heat exchanger 11, which is arranged in the accommodating cavity corresponding to the side air inlet 9 and is located between the first centrifugal fan 8 and the side air inlet 9. The second heat exchanger 11 is used to adjust the temperature of the airflow entering from the side air inlet 9 and to exchange heat with it.

[0041] In this embodiment, the first heat exchanger 7 and the second heat exchanger 11 are connected by a bent tube or a hose to achieve the communication of the refrigerant. Alternatively, the first heat exchanger 7 is a bent structure, and the first heat exchanger 7 includes a first heat exchange part corresponding to the air inlet 3 and a second heat exchange part corresponding to the side air inlet 9. The first heat exchange part and the second heat exchange part are integrally formed.

[0042] Optionally, the outdoor unit further includes a compressor assembly 12, which is disposed in the accommodating cavity and between the air inlet 3 and the air outlet 4. The compressor assembly 12 includes a compressor 21 and a plurality of partitions disposed outside the compressor 21, and the plurality of partitions enclose the compressor 21 in an independent space.

[0043] Specifically, the compressor 21 is surrounded by a space consisting of the first side wall 2, the top wall, the bottom wall, and the partition, etc. The compressor is not located in the air duct to meet the requirements of safety and performance, and the compressor 21 is separated from the air duct by the partition.

[0044] The first heat exchanger 7 and the second heat exchanger 11 are connected to the compressor 21 to realize refrigerant transmission.

[0045] In this embodiment, the outdoor unit further includes a first baffle assembly 13, which is connected to the outlet of the first centrifugal fan 8 and cooperates with the compressor assembly 12 to divide the accommodating chamber into an air inlet side space and an air outlet side space. The first baffle assembly 13 cooperates with the compressor assembly 12 to divide the accommodating chamber into an air inlet side space and an air outlet side space, so that the airflow entering from the air inlet 3 and the side air inlet 9 passes through the corresponding heat exchanger for heat exchange, and then flows out from the outlet of the first centrifugal fan 8 through the first centrifugal fan 8.

[0046] In this embodiment, the ventilation area of ​​the first baffle assembly 13 gradually increases from the inlet to the outlet. In this embodiment, the first baffle assembly 13 includes a plurality of baffles, for example, baffle a19 and b20. The first baffle assembly 13 is formed by arranging four baffles at the outlet of the first centrifugal fan 8, and the sides of the four baffles are connected to form an air duct.

[0047] The joints where the four partitions are connected to the partitions of the outdoor unit housing 1 and the compressor assembly 12 are sealed to prevent air leakage.

[0048] Optionally, the outdoor unit further includes a guide plate 14, which is disposed in the air outlet side space and located on a side of the outdoor unit housing 1 away from the air outlet 4. The guide plate 14 is used to guide the gas flowing out of the first baffle assembly 13 to reduce noise.

[0049] Optionally, the guide plate 14 is an arc-shaped guide plate 14. The arc-shaped guide plate 14 can make the gas turn more smoothly. The single fan structure air outlet duct adopts the guide plate 14 to reduce local pressure loss. The guide plate 14 adopts an arc structure to better organize the airflow and reduce local pressure loss. One end of the guide plate is installed on the second side wall, and the other end is installed on the fourth side wall, and the upper and lower parts are respectively in contact with the bottom wall and the top wall.

[0050] Optionally, according to different air volume requirements, the outdoor unit further includes a second centrifugal fan 15, which is arranged in the air outlet side space and corresponds to the outlet of the first baffle assembly 13, and the axis of the second centrifugal fan 15 is perpendicular to the axis of the first centrifugal fan 8. The dual fan structure is arranged in series, and the center of the first fan outlet and the second fan inlet are staggered.

[0051] Optionally, the outdoor unit also includes a second baffle assembly 16, which is arranged in the air outlet side space, and the inlet of the second baffle assembly 16 is connected to the outlet of the second centrifugal fan 15. Along the inlet to the outlet direction of the second baffle assembly 16, the ventilation area of ​​the second baffle assembly 16 gradually increases.

[0052] Optionally, the outdoor unit further includes a third heat exchanger 17 , which is disposed at an outlet of the first baffle assembly 13 .

[0053] Optionally, the outdoor unit further includes a fourth heat exchanger 18 , which is disposed at an outlet of the second baffle assembly 16 .

[0054] In addition to the compressor 21, the heat exchanger, the first centrifugal fan 8, etc., the outdoor unit also includes structures such as a four-way valve, pipe fittings and an electrical box. The first three occupy the largest space, and the remaining components can be arranged according to actual conditions and are not described in detail.

[0055] The first side wall 2, the bottom wall, the top wall, the second side wall, the third side wall and the fourth side wall may be provided with functional holes in parts that are not in the air inlet or air outlet ducts, but no holes may be opened in the parts located in the air ducts.

[0056] The first side wall 2 forms an air inlet 3 through the air inlet louver (first air guide plate 5). The third side wall (right side panel) adopts a mesh cover or a grille structure to form a side air inlet 9. The exhaust louver forms an air outlet 4 on the first side wall 2. The air inlet louver and the air outlet louver have opposite opening directions to prevent the outlet air from directly returning to the air inlet and causing air flow short circuit.

[0057] The top wall, the bottom wall, the second side wall, the first baffle assembly 13, the compressor assembly 12, etc. form an air inlet duct. The top wall, the bottom wall, the second side wall, the fourth side wall, the guide plate 14, etc. form an air outlet duct. The air inlet duct and the air outlet duct are connected through the air duct of the first baffle assembly 13.

[0058] like Figure 3 As shown, when the single-fan outdoor unit is working, air enters from the air inlet 3 and the side air inlet 9, and after heat exchange through the first heat exchanger 7 and the second heat exchanger, is sucked in from the inlet of the first centrifugal fan 8, and is discharged from its outlet, and is discharged from the air outlet 4 after being guided by the first partition assembly 13 and the guide plate 14.

[0059] When a dual-fan outdoor unit structure is adopted, the outdoor unit is a tandem dual-fan horizontal outdoor unit structure. On the basis of the single-fan structure, a third heat exchanger, a fourth heat exchanger, a second centrifugal fan and a second partition assembly are added. The guide plate 14 is cancelled.

[0060] The second heat exchanger may be disposed at the outlet of the first partition assembly 13 , with its respective sides contacting the top wall, the second side wall, the bottom wall, and the partition of the compressor assembly 12 .

[0061] The second fan is also a centrifugal fan, and is connected in series with the first centrifugal fan. Its axis is staggered with the outlet center line of the first centrifugal fan 8 and is arranged at different heights to reduce uneven heat exchange of the third heat exchanger.

[0062] The second partition assembly 16 cooperates with the compressor assembly 12 to divide the air outlet side space into two parts, so that the airflow passes through the fourth heat exchanger 18 and then flows out from the air outlet 4.

[0063] like Figure 5 As shown, when the outdoor unit of the dual-fan is working, air enters from the air inlet 3 and the side air inlet 9, and after heat exchange through the first heat exchanger 7 and the second heat exchanger 11, it is sucked in from the inlet of the first centrifugal fan 8, and discharged from its outlet, passes through the first baffle assembly 13, and then enters the third heat exchanger 17 for heat exchange, and is then sucked in and pressurized by the inlet of the second centrifugal fan 15 and discharged, passes through the second baffle assembly 16, enters the fourth heat exchanger 18 for heat exchange, and is discharged from the air outlet 4.

[0064] like Figure 1 and 2 As shown, when installing the outdoor unit, without affecting the appearance, the surface (first side wall 2) where the air inlet 3 and the air outlet 4 of the outdoor unit are located needs to be close to the beautifying building grille 25. Preferably, the distance between the first side wall 2 and the building grille 25 ranges from 1 to 3 cm.

[0065] If the actual situation does not allow such installation, a baffle 24 can be placed in front of the first side wall 2 at the same plane to further separate the air inlet 3 and the air outlet 4 to prevent short-circuiting of the air flow.

[0066] According to another aspect of the present invention, an air conditioner is provided, which includes the above-mentioned outdoor unit. The outdoor unit can solve the problem that a large unit cannot be installed when a building only provides a low embedded installation space, and solve the problem of short circuit of inlet and outlet airflow in the embedded installation space.

[0067] The outdoor unit according to the present invention and the air conditioner having the same have the following technical effects:

[0068] The outdoor unit is a horizontal structure that can be equipped with single or double fans, and can adapt to the situation where the building installation space is shorter.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
