TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning equipment, in particular to an air conditioner outdoor unit and air conditioning equipment. BACKGROUND

[0002] The wall-mounted air conditioning equipment is the most common and widely used type of air conditioning equipment, which includes an indoor wall-mounted machine and an air conditioner outdoor unit. At present, the air conditioner outdoor unit of the wall-mounted air conditioning equipment is generally large in size and larger than the indoor wall-mounted machine. Therefore, the air conditioner outdoor unit of the wall-mounted air conditioning equipment occupies more space during transportation.

[0003] During transportation of the wall-mounted air conditioning equipment, a transport vehicle needs to be matched with a number of indoor wall-mounted machines and air conditioner outdoor units, usually 1:1. The air conditioner outdoor unit may occupy up to 2 / 3 of the entire vehicle, which limits the number of wall-mounted air conditioning equipment that can be transported by the transport vehicle and may waste the transportation space of the transport vehicle, causing transportation waste and increasing transportation costs. SUMMARY

[0004] The purpose of the present application is to provide an air conditioner outdoor unit and air conditioning equipment. The air conditioner outdoor unit adopts a stretchable and retractable structure, which can be retracted to a smaller size during transportation, reducing the space occupied during transportation, thereby increasing the number of wall-mounted air conditioning equipment that can be transported by the transport vehicle, reducing the waste of transportation space, and reducing transportation costs.

[0005] To achieve the above purpose, in a first aspect, the present application provides an air conditioner outdoor unit, comprising:

[0006] An outdoor unit main body, which is stretchably arranged;

[0007] An outdoor unit fan blade, which is foldably arranged in the outdoor unit main body;

[0008] When the outdoor unit main body is in a retracted state, the outdoor unit fan blade is in a folded state in the outdoor unit main body.

[0055] At present, the air conditioner outdoor unit of the wall-mounted air conditioning equipment is generally large in size, and is larger than the size of the indoor wall-mounted machine, so it occupies more space during transportation. When the wall-mounted air conditioning equipment is transported, a transport vehicle needs to be matched with a number of indoor wall-mounted machines and air conditioner outdoor units, usually 1:1, wherein the occupied space of the air conditioner outdoor unit may reach 2 / 3 of the whole vehicle, so as to limit the number of wall-mounted air conditioning equipment that can be transported by the transport vehicle, and may waste the transportation space of the transport vehicle, causing transportation waste and increasing transportation cost.

[0056] In view of the problems in the prior art, the air conditioner outdoor unit and the air conditioning equipment provided by the embodiments of the present application adopt a stretchable and retractable structure, which can be retracted to a smaller size during transportation, reducing the space occupied during transportation, thereby improving the number of wall-mounted air conditioning equipment that can be transported by the transport vehicle, reducing the waste of transportation space, and reducing the transportation cost.

[0057] Embodiment one

[0058] Referring to Figures 1 to 3 The air conditioner outdoor unit of the embodiments of the present application comprises:

[0059] The outdoor unit main body 10 is stretchably arranged;

[0060] The outer unit fan blade 20 is foldably arranged in the outdoor unit main body 10.

[0061] When the outdoor unit main body 10 is in the contracted state, the outer unit fan blade 20 is in the folded state in the outdoor unit main body 10.

[0062] The air conditioner outdoor unit of the embodiment can be used as an air conditioner outdoor unit of a wall-mounted air conditioning device, and can also be used as an air conditioner outdoor unit of other types of air conditioning devices, for example, as an air conditioner outdoor unit of a floor-standing air conditioning device. In this embodiment, the air conditioner outdoor unit of the embodiment is unfolded, described and explained as an air conditioner outdoor unit of a wall-mounted air conditioning device.

[0063] In this embodiment, the outdoor unit main body 10 is arranged in a stretchable manner. That is, the outdoor unit main body 10 can be adjusted by stretching, so that the outdoor unit main body 10 is in a contracted state or an unfolded state. When the outdoor unit main body 10 is in the contracted state, the volume of the outdoor unit main body 10 is relatively reduced. When the outdoor unit main body 10 is in the unfolded state, the volume of the outdoor unit main body 10 is relatively increased, and can be restored to a normal volume.

[0064] In this embodiment, the outer unit fan blade 20 is arranged in a foldable manner. That is, the outer unit fan blade 20 can be adjusted to be in a folded state or an unfolded state. When the outer unit fan blade 20 is in the folded state, the occupied volume of the outer unit fan blade 20 is relatively reduced, matching the contracted state of the outdoor unit main body 10. When the outer unit fan blade 20 is in the unfolded state, the occupied volume of the outer unit fan blade 20 is relatively increased, matching the unfolded state of the outdoor unit main body 10.

[0065] In this embodiment, when the air conditioner outdoor unit needs to be transported, the outdoor unit main body 10 is in the contracted state, and the outer unit fan blade 20 is in the folded state in the outdoor unit main body 10. When the air conditioner outdoor unit is installed and used, the outdoor unit main body 10 is adjusted by stretching to be in the unfolded state, and the outer unit fan blade 20 is adjusted to be in the unfolded state for normal use.

[0066] The air conditioner outdoor unit of the embodiment adopts a stretchable and contractible structure. The outdoor unit main body 10 is arranged in a stretchable manner, and the outer unit fan blade 20 is arranged in a foldable manner. When transported, the outdoor unit main body 10 can be in the contracted state, and the outer unit fan blade 20 can be in the folded state in the outdoor unit main body 10, so that the air conditioner outdoor unit can be contracted to a smaller volume state, reducing the space occupied during transportation, freeing up more space for placing indoor wall-mounted machines, thereby increasing the number of wall-mounted air conditioning devices that can be transported by a transport vehicle, reducing the waste of transport space of the transport vehicle, and reducing the transportation cost of the wall-mounted air conditioning device.

[0067] In addition, during installation and use of the air conditioner outdoor unit, the outdoor unit body 10 can be stretched to an unfolded state, restored to a regular size air conditioner outdoor unit, and the outdoor unit fan blade 20 can be in an unfolded state, without affecting normal use of the air conditioner outdoor unit.

[0068] Embodiment Two

[0069] Referring to Figures 1 to 5 In the above embodiment one, the air conditioner outdoor unit of the present embodiment includes an outdoor unit body 10, which includes an outdoor unit shell 11, the outdoor unit shell 11 including an upper shell 111, an intermediate shell 112, a lower shell 113, a top cover 114, and a bottom plate 115,

[0070] The upper shell 111 and the upper part of the intermediate shell 112 are stretchably nested and connected, and the lower shell 113 and the lower part of the intermediate shell 112 are stretchably nested and connected.

[0071] The top cover 114 is arranged on the upper shell 111, and the bottom plate 115 is arranged on the lower shell 113.

[0072] In the present embodiment, the upper shell 111 and the upper part of the intermediate shell 112 are slidingly connected, forming a stretchable nested connection structure; and the lower shell 113 and the lower part of the intermediate shell 112 are slidingly connected, forming a stretchable nested connection structure.

[0073] In the above structure, the contraction and expansion of the outdoor unit shell 11 are achieved through stretchable nesting of the upper part of the upper shell 111 and the intermediate shell 112 and stretchable nesting of the lower part of the lower shell 113 and the intermediate shell 112. This structure of the outdoor unit shell 11 stretching and contracting can facilitate contraction and expansion of the outdoor unit shell 11, and can better guarantee consistency, structural stability, and structural strength of the outdoor unit shell 11 after contraction and expansion.

[0074] Further, in the present embodiment, a limiting buckle 116 is arranged on each of the upper shell 111, the intermediate shell 112, and the lower shell 113.

[0075] When the outdoor unit shell 11 is in a fully unfolded state, the upper shell 111 and the intermediate shell 112, and the lower shell 113 and the intermediate shell 112 are locked by the limiting buckle 116.

[0076] Exemplarily, the upper shell 111 and the middle shell 112 can correspondingly be provided with matched limiting buckles 116, and when the outdoor unit shell 11 is in the fully unfolded state, the upper shell 111 and the middle shell 112 are locked by the matched limiting buckles 116. Similarly, the lower shell 113 and the middle shell 112 can correspondingly be provided with matched limiting buckles 116, and when the outdoor unit shell 11 is in the fully unfolded state, the lower shell 113 and the middle shell 112 are locked by the matched limiting buckles 116.

[0077] The limiting buckles 116 are relatively common structure locking members, and in the embodiment, the type and structure of the limiting buckles 116 that can be used by the outdoor unit shell 11 are not exemplified.

[0078] In the above structure, the limiting buckles 116 can lock the upper shell 111 and the middle shell 112, and the lower shell 113 and the middle shell 112 when the outdoor unit shell 11 is in the fully unfolded state. The limiting buckles 116 are provided to facilitate the fixation of the structure of the outdoor unit shell 11 when the outdoor unit shell 11 is unfolded, and can better stabilize the structure of the outdoor unit shell 11 in the fully unfolded state, and better guarantee the structural stability and structural strength of the outdoor unit shell 11.

[0079] Further, in the embodiment, the outdoor unit body 10 further includes a mounting bracket 12, and the mounting bracket 12 includes an upper bracket 121, a middle bracket 122, and a lower bracket 123,

[0080] The upper bracket 121 and the upper part of the middle bracket 122 can be stretchably nested and connected, and the lower bracket 123 and the lower part of the middle bracket 122 can be stretchably nested and connected.

[0081] The top end of the upper bracket 121 is connected to the top cover 114, and the bottom end of the lower bracket 123 is connected to the bottom disc 115.

[0082] In the embodiment, the upper bracket 121 and the upper part of the middle bracket 122 are slidingly connected to form a stretchable nested connection structure, and the lower bracket 123 and the lower part of the middle bracket 122 are slidingly connected to form a stretchable nested connection structure.

[0083] In the above structure, the contraction and expansion of the mounting bracket 12 is realized by the stretching and nesting of the upper bracket 121 with the upper part of the middle bracket 122 and the stretching and nesting of the lower bracket 123 with the lower part of the middle bracket 122. This structure of the stretching and contraction of the mounting bracket 12 can facilitate the contraction and expansion of the mounting bracket 12 and the outdoor unit main body 10. Since the top end of the upper bracket 121 is connected to the top cover 114, which is arranged on the upper shell 111, and the bottom end of the lower bracket 123 is connected to the bottom plate 115, which is arranged on the lower shell 113, the stretching and contraction of the mounting bracket 12 is synchronized with the stretching and contraction of the outdoor unit shell 11. In addition, this can facilitate the arrangement of other structures (for example, the outdoor unit heat exchanger 13) of the outdoor unit main body 10 and the arrangement of other components, thereby reducing the modification of the internal structure of the outdoor unit of the air conditioner and ensuring the stability and performance of the operation of the outdoor unit of the air conditioner.

[0084] Further, in the present embodiment, the outdoor unit main body 10 further comprises an outdoor unit heat exchanger 13, which comprises an upper heat exchanger 131 and a lower heat exchanger 132,

[0085] The upper heat exchanger 131 is arranged on the upper bracket 121, and the lower heat exchanger 132 is arranged on the lower bracket 123, and the lower heat exchanger 132 is arranged in a staggered manner with the upper heat exchanger 131.

[0086] It can be understood that the lower heat exchanger 132 is arranged in a staggered manner with the upper heat exchanger 131, i.e., the positions of the lower heat exchanger 132 and the upper heat exchanger 131 are staggered. In the present embodiment, the positions of the lower heat exchanger 132 and the upper heat exchanger 131 are staggered in the vertical direction.

[0087] In the above structure, the lower heat exchanger 132 is arranged in a staggered manner with the upper heat exchanger 131, which can facilitate the arrangement of the outdoor unit heat exchanger 13 in the outdoor unit main body 10. In addition, the upper heat exchanger 131 is arranged on the upper bracket 121, and the lower heat exchanger 132 is arranged on the lower bracket 123. When the mounting bracket 12 is stretched and contracted, since the upper heat exchanger 131 is arranged on the upper bracket 121 and the lower heat exchanger 132 is arranged on the lower bracket 123, the stretching and contraction of the outdoor unit heat exchanger 13 is synchronized with the stretching and contraction of the mounting bracket 12. Thus, the contraction and expansion of the outdoor unit heat exchanger 13 and the outdoor unit main body 10 can be facilitated.

[0088] Embodiment Three

[0089] Referring to Figures 1 to 7 On the basis of the above-mentioned embodiment one or embodiment two, the outdoor unit of the air conditioner of the present embodiment comprises a fan blade 20, which comprises a fan hub 21 and a plurality of fan blades 22,

[0090] The fan hub 21 is arranged in the outdoor unit main body 10, and a plurality of fan blades 22 are arranged on the fan hub 21, each fan blade 22 being foldably arranged.

[0091] When the outdoor unit main body 10 is in the retracted state, the fan blades 22 are in the folded state in the outdoor unit main body 10.

[0092] In the present embodiment, the fan blades 22 are provided in three, and it can be understood that in other embodiments, the fan blades 22 can also be provided in other numbers, for example, the fan blades 22 can also be provided in five.

[0093] In the present embodiment, when the fan blades 22 are in the folded state, i.e., the outdoor fan 20 is in the folded state; correspondingly, when the fan blades 22 are in the unfolded state, i.e., the outdoor fan 20 is in the unfolded state.

[0094] In the above structure, the folding and unfolding of the outdoor fan 20 are realized by the folding and unfolding of the plurality of fan blades 22, so that the folding and unfolding of the outdoor fan 20 can be more convenient, and the internal space in the outdoor unit main body 10 can be better utilized, and the unfolding of the outdoor fan 20 can be facilitated when the air conditioner outdoor unit is installed or used.

[0095] Further, in the present embodiment, a fan driving member 31 is arranged in the outdoor unit main body 10, and the fan hub 21 is arranged on the fan driving member 31.

[0096] Specifically, on the basis of Embodiment Two, the fan driving member 31 is arranged on the middle support 122, and the rotation of the fan hub 21 is driven by the fan driving member 31.

[0097] Exemplarily, the fan driving member 31 is a fan driving motor.

[0100] The first sub-blade 221 is arranged on the fan hub 21, and a blade rotating shaft 223 is arranged on one side of the first sub-blade 221;

[0101] The second sub-blade 222 is adapted to the first sub-blade 221, and the second sub-blade 222 is rotatably connected to the first sub-blade 221 through the blade rotating shaft 223, so that the fan blade 22 can be foldably arranged or unfolded.

[0102] In the embodiment, the first sub-blade 221 is fixedly arranged on the fan hub 21, and the second sub-blade 222 is rotatably connected to the first sub-blade 221 through the blade rotating shaft 223. In use of the outdoor unit, the second sub-blade 222 can gradually unfold relative to the first sub-blade 221 along with the rotation of the fan hub 21 and the first sub-blade 221, until the second sub-blade 222 is fully unfolded and returns to the normal shape.

[0103] In the above structure, the second sub-blade 222 is rotatably connected to the first sub-blade 221 through the blade rotating shaft 223, so that the fan blade 22 can be folded or unfolded. In use of the outdoor unit, the plurality of fan blades 22 of the outdoor fan 20 can unfold along with the rotation of the fan hub 21, and return to the normal shape of the fan blade 22, thereby ensuring the normal use of the outdoor fan 20.
