Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and more specifically, to an outdoor air conditioning unit and air conditioning equipment. Background Technology

[0002] Wall-mounted air conditioning units are the most common and widely used type of air conditioning equipment. They include indoor wall-mounted units and outdoor units. Currently, the outdoor units of wall-mounted air conditioning units are generally larger than the indoor units, so they take up more space during transportation.

[0003] When transporting wall-mounted air conditioning equipment, a transport vehicle typically needs to be equipped with an indoor wall-mounted unit and an outdoor air conditioning unit in a 1:1 ratio. The outdoor air conditioning unit may occupy up to 2 / 3 of the entire vehicle's space, which limits the number of wall-mounted air conditioning units that the transport vehicle can carry. This may also waste transport space, resulting in transportation waste and increased transport costs. Utility Model Content

[0004] The purpose of this application is to provide an outdoor air conditioning unit and air conditioning equipment. The outdoor air conditioning unit adopts a stretchable and retractable structure, which can be retracted to a smaller volume during transportation, reducing the space it occupies during transportation. This can increase the number of wall-mounted air conditioning units that can be transported by the transport vehicle, reduce the waste of transportation space, and lower transportation costs.

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

[0006] The outdoor unit body is extendable;

[0007] The outdoor unit fan blades are foldable and are housed within the outdoor unit body.

[0008] When the outdoor unit body is in a retracted state, the outdoor unit fan blades are folded within the outdoor unit body.

[0009] In the implementation of the above technical solution, the outdoor unit of the air conditioner adopts a stretchable and retractable structure. The main body of the outdoor unit is stretchable and the fan blades are foldable. During transportation, the main body of the outdoor unit can be in a retracted state, and the fan blades can be in a folded state within the main body of the outdoor unit. This allows the outdoor unit of the air conditioner to be reduced to a smaller volume, reducing the space it occupies during transportation and freeing up more space for indoor wall-mounted units. This increases the number of wall-mounted air conditioning units that can be transported by the transport vehicle, reduces the waste of transport space, and lowers the transportation cost of the wall-mounted air conditioning units.

[0010] In addition, during the installation and use of the outdoor unit, the main body of the outdoor unit can be extended to the unfolded state, restoring it to the normal size of the outdoor unit, and the fan blades of the outdoor unit can be in the unfolded state, without affecting the normal use of the outdoor unit.

[0011] In a preferred embodiment of this application, the outdoor unit body includes an outdoor unit housing, which includes an upper housing, a middle housing, a lower housing, a top cover, and a chassis.

[0012] The upper shell is stretchably nested with the upper part of the middle shell, and the lower shell is stretchably nested with the lower part of the middle shell.

[0013] The top cover is disposed on the upper housing, and the chassis is disposed on the lower housing.

[0014] In the process of implementing the above technical solution, the shrinking and unfolding of the outdoor unit casing is achieved by stretching and nesting the upper part of the upper casing and the middle casing, and stretching and nesting the lower part of the lower casing and the middle casing. This structure of stretching and shrinking the outdoor unit casing facilitates the shrinking and unfolding of the outdoor unit casing, and can better ensure the consistency of the outdoor unit casing after shrinking and unfolding, as well as the structural stability and structural strength.

[0015] In a preferred embodiment of this application, the outdoor unit body further includes a mounting bracket, which comprises an upper bracket, a middle bracket, and a lower bracket.

[0016] The upper support is stretchably nested with the upper part of the middle support, and the lower support is stretchably nested with the lower part of the middle support.

[0017] The top end of the upper bracket is connected to the top cover, and the bottom end of the lower bracket is connected to the chassis.

[0018] In the implementation of the above technical solution, the retraction and expansion of the mounting bracket are achieved through the stretching and nesting of the upper bracket and the middle bracket at the top, and the stretching and nesting of the lower bracket and the middle bracket at the bottom. This structure of stretching and retracting of the mounting bracket facilitates the retraction and expansion of the mounting bracket and the outdoor unit body. The stretching and retraction of the mounting bracket is synchronized with the stretching and retraction of the outdoor unit casing. Furthermore, it facilitates the installation of other structures (e.g., outdoor unit heat exchanger) and other components of the outdoor unit body, thereby reducing modifications to the internal structure of the air conditioner outdoor unit and ensuring the stability and performance of the air conditioner outdoor unit.

[0019] In a preferred embodiment of this application, the outdoor unit body further includes an outdoor unit heat exchanger, which comprises an upper heat exchanger and a lower heat exchanger.

[0020] The upper heat exchanger is mounted on the upper support, and the lower heat exchanger is mounted on the lower support, with the lower heat exchanger and the upper heat exchanger being offset from each other.

[0021] In the implementation of the above technical solution, the lower heat exchanger and the upper heat exchanger are staggered, which facilitates the installation of the outdoor unit heat exchanger on the outdoor unit body. Furthermore, the upper heat exchanger is installed on the upper bracket and the lower heat exchanger is installed on the lower bracket. When the mounting bracket is stretched or contracted, the outdoor unit heat exchanger is stretched or contracted synchronously with the mounting bracket. This facilitates the contraction and expansion of the outdoor unit heat exchanger and the outdoor unit body.

[0022] In a preferred embodiment of this application, limit buckles are provided on the upper housing, the intermediate housing, and the lower housing;

[0023] When the outdoor unit casing is in the fully extended state, the upper casing and the middle casing, as well as the lower casing and the middle casing, are locked together by the limiting buckle.

[0024] In the implementation of the above technical solution, the limit buckle can lock the upper shell and the middle shell, and the lower shell and the middle shell when the outdoor unit shell is in the fully unfolded state. The limit buckle can facilitate the fixation of the outdoor unit shell structure when the outdoor unit shell is unfolded, and can better stabilize the structure of the outdoor unit shell when it is in the fully unfolded state, thus better ensuring the stability and strength of the outdoor unit shell structure.

[0025] In a preferred embodiment of this application, the outdoor unit fan blades include a fan hub and multiple fan blades.

[0026] The impeller hub is disposed in the outdoor unit body, and a plurality of impeller blades are disposed on the impeller hub, each impeller blade being foldable;

[0027] When the outdoor unit body is in a retracted state, the fan blades are folded within the outdoor unit body.

[0028] In the implementation of the above technical solution, the folding and unfolding of the outdoor unit fan blades is achieved by folding and unfolding multiple fan blades. This makes it easier to fold and unfold the outdoor unit fan blades, makes better use of the internal space in the outdoor unit body, and facilitates the unfolding of the outdoor unit fan blades when the outdoor unit is installed or used.

[0029] In a preferred embodiment of this application, each of the wind turbine blades includes a first segmented blade and a second segmented blade.

[0030] The first blade is disposed on the wind turbine hub, and a blade shaft is disposed on one side of the first blade;

[0031] The second blade is adapted to the first blade, and the second blade is rotatably connected to the first blade via the blade pivot, so that the wind turbine blade can be folded or unfolded.

[0032] In the implementation of the above technical solution, the second blade is rotatably connected to the first blade via a blade shaft, allowing the fan blades to be folded or unfolded. With this structure, when the outdoor unit of the air conditioner is in use, the multiple fan blades of the outdoor unit can unfold with the rotation of the fan hub, restoring to the normal shape of the fan blades, ensuring the normal use of the outdoor unit fan blades. This facilitates the installation of the outdoor unit of the air conditioner, eliminating the need for installers to open the outdoor unit to adjust the shape of the fan blades during installation.

[0033] In a preferred embodiment of this application, a rotation limiting part is provided on the blade shaft, and the rotation limiting part is used to limit the rotation angle of the second blade.

[0034] In the implementation of the above technical solution, the setting of the rotation limit part can limit the rotation angle of the second blade, so that the fan blade unfolds to a specific shape as the fan hub rotates, and maintains this specific shape in the subsequent process, avoiding the continuous switching of the fan blade shape, ensuring the quality of the fan blade and the outdoor unit fan blade, and thus ensuring the use quality and product performance of the air conditioner outdoor unit.

[0035] In a preferred embodiment of this application, a fan blade drive component is provided in the outdoor unit body, and the fan blade hub is disposed on the fan blade drive component.

[0036] In the implementation of the above technical solution, the rotation of the wind turbine hub is driven by the wind turbine drive component.

[0037] Secondly, this application provides an air conditioning device, including the aforementioned outdoor air conditioning unit.

[0038] This application discloses an outdoor air conditioning unit and air conditioning equipment, which, compared with the prior art, has at least the following advantages:

[0039] The outdoor unit of this application includes an outdoor unit body and an outdoor unit fan blade. The outdoor unit body is extendable, and the outdoor unit fan blade is foldable and housed within the outdoor unit body. This outdoor unit employs a stretchable and retractable structure. During transportation, the outdoor unit body can be retracted, and the outdoor unit fan blade can be folded within the outdoor unit body. This allows the outdoor unit to be reduced to a smaller size, minimizing the space it occupies during transportation and freeing up more space for indoor wall-mounted units. This increases the number of wall-mounted air conditioning units that can be transported by a vehicle, reducing wasted transport space and lowering transportation costs. Furthermore, during installation and use, the outdoor unit body can be extended to a conventional size, and the outdoor unit fan blade can remain extended without affecting the normal operation of the outdoor unit.

[0040] The air conditioning equipment of this application uses the aforementioned outdoor air conditioning unit. During transportation, the outdoor air conditioning unit can be retracted to a smaller size, reducing the space it occupies during transportation and freeing up more space for indoor wall-mounted units. This increases the number of wall-mounted air conditioning units that can be transported by the transport vehicle, reduces the waste of transport space, and lowers the transportation cost of the wall-mounted air conditioning units.

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Unless otherwise stated, "a plurality of" means two or more.

[0055] Currently, the outdoor units of wall-mounted air conditioners are generally quite large, and even larger than the indoor units. Therefore, they take up more space during transportation. Typically, a transport vehicle needs to carry an indoor unit and an outdoor unit in a 1:1 ratio, with the outdoor unit occupying up to two-thirds of the vehicle's space. This limits the number of wall-mounted air conditioners a vehicle can transport, potentially wasting transport space and increasing costs.

[0056] To address the problems in the prior art, this application provides an outdoor air conditioning unit and air conditioning equipment. The outdoor air conditioning unit adopts a stretchable and retractable structure, which can be retracted to a smaller volume during transportation, reducing the space it occupies during transportation. This increases the number of wall-mounted air conditioning units that can be transported by the transport vehicle, reduces the waste of transportation space, and lowers transportation costs.

[0057] Example 1

[0058] See Figures 1 to 3 The outdoor unit of the air conditioner in this application embodiment includes:

[0059] The outdoor unit body 10 is extendable;

[0060] The outdoor unit fan blade 20 is foldable and is located in the outdoor unit body 10.

[0061] When the outdoor unit body 10 is in the retracted state, the outdoor unit fan blades 20 are in the folded state within the outdoor unit body 10.

[0062] The outdoor unit of the air conditioner in this embodiment can be used as the outdoor unit of a wall-mounted air conditioner or as the outdoor unit of other types of air conditioners, such as the outdoor unit of a floor-standing air conditioner. In this embodiment, the outdoor unit of the air conditioner in this embodiment is described and explained using the outdoor unit of a wall-mounted air conditioner.

[0063] In this embodiment, the outdoor unit body 10 is stretchable. That is, the outdoor unit body 10 can be stretched and adjusted to be in two states: retracted and extended. When the outdoor unit body 10 is in the retracted state, the volume of the outdoor unit body 10 is relatively reduced. When the outdoor unit body 10 is in the extended state, the volume of the outdoor unit body 10 is relatively increased, and it can be restored to its normal size.

[0064] In this embodiment, the outdoor unit fan blades 20 are foldable. In other words, the outdoor unit fan blades 20 can be adjusted to be in two states: folded and unfolded. When the outdoor unit fan blades 20 are in the folded state, the volume occupied by the outdoor unit fan blades 20 is relatively smaller, matching the outdoor unit body 10 in a retracted state. When the outdoor unit fan blades 20 are in the unfolded state, the volume occupied by the outdoor unit fan blades 20 is relatively larger, matching the outdoor unit body 10 in an unfolded state.

[0065] In this embodiment, when the outdoor unit needs to be transported, the outdoor unit body 10 is in a retracted state, and the outdoor unit fan blades 20 are in a folded state within the outdoor unit body 10; when the outdoor unit is installed and used, the outdoor unit body 10 is stretched and adjusted to be in an unfolded state, and the outdoor unit fan blades 20 are adjusted to be in an unfolded state for normal use.

[0066] The outdoor unit of the air conditioner in this embodiment adopts a stretchable and retractable structure. The outdoor unit body 10 is stretchable and the outdoor unit fan blades 20 are foldable. During transportation, the outdoor unit body 10 can be in a retracted state and the outdoor unit fan blades 20 can be in a folded state within the outdoor unit body 10. This allows the outdoor unit to be retracted to a smaller volume, reducing the space it occupies during transportation and freeing up more space for indoor wall-mounted units. This increases the number of wall-mounted air conditioning units that can be transported by the transport vehicle, reduces the waste of transport space, and lowers the transportation cost of the wall-mounted air conditioning units.

[0067] In addition, during the installation and use of the outdoor unit, the outdoor unit body 10 can be extended to the unfolded state, restoring it to the normal size of the outdoor unit, and the outdoor unit fan blades 20 can be in the unfolded state, without affecting the normal use of the outdoor unit.

[0068] Example 2

[0069] See Figures 1 to 5 Based on the above embodiment one, the outdoor unit of the air conditioner in this embodiment includes an outdoor unit housing 11, which comprises an upper housing 111, a middle housing 112, a lower housing 113, a top cover 114, and a chassis 115.

[0070] The upper shell 111 and the upper part of the middle shell 112 are connected in a stretchable nested connection, and the lower shell 113 and the lower part of the middle shell 112 are connected in a stretchable nested connection.

[0071] The top cover 114 is mounted on the upper housing 111, and the chassis 115 is mounted on the lower housing 113.

[0072] In this embodiment, the upper shell 111 is slidably connected to the upper part of the middle shell 112 to form a stretchable nested connection structure; the lower shell 113 is slidably connected to the lower part of the middle shell 112 to form a stretchable nested connection structure.

[0073] In the above structure, the expansion and contraction of the outdoor unit housing 11 are achieved by the upper shell 111 and the middle shell 112 being stretched and nested at the top, and the lower shell 113 and the middle shell 112 being stretched and nested at the bottom. This structure of the outdoor unit housing 11 being stretched and contracted facilitates the expansion and contraction of the outdoor unit housing 11 and can better ensure the consistency of the outdoor unit housing 11 after expansion and contraction, as well as the structural stability and structural strength.

[0074] Furthermore, in this embodiment, limit buckles 116 are provided on the upper shell 111, the middle shell 112 and the lower shell 113;

[0075] When the outdoor unit housing 11 is in the fully extended state, the upper housing 111 and the middle housing 112, and the lower housing 113 and the middle housing 112 are locked by the limit buckle 116.

[0076] For example, corresponding limiting buckles 116 may be provided on the upper housing 111 and the middle housing 112. When the outdoor unit housing 11 is in the fully extended state, the upper housing 111 and the middle housing 112 are locked by the corresponding limiting buckles 116. Similarly, corresponding limiting buckles 116 may be provided on the lower housing 113 and the middle housing 112. When the outdoor unit housing 11 is in the fully extended state, the lower housing 113 and the middle housing 112 are locked by the corresponding limiting buckles 116.

[0077] The limiting buckle 116 is a relatively conventional structural locking component. In this embodiment, the type and structure of the limiting buckle 116 that can be used on the outdoor unit housing 11 will not be exemplified.

[0078] In the above structure, the limiting buckle 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 extended state. The setting of the limiting buckle 116 can facilitate the fixation of the outdoor unit shell 11 structure when the outdoor unit shell 11 is extended, and can better stabilize the structure of the outdoor unit shell 11 when it is in the fully extended state, thus better ensuring the structural stability and structural strength of the outdoor unit shell 11.

[0079] Furthermore, in this embodiment, the outdoor unit body 10 also includes a mounting bracket 12, which includes an upper bracket 121, a middle bracket 122, and a lower bracket 123.

[0080] The upper support 121 and the upper part of the middle support 122 are connected in a stretchable nested connection, and the lower support 123 and the lower part of the middle support 122 are connected in a stretchable nested connection.

[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 chassis 115.

[0082] In this embodiment, the upper support 121 is slidably connected to the upper part of the middle support 122 to form a stretchable nested connection structure, and the lower support 123 is slidably connected to the lower part of the middle support 122 to form a stretchable nested connection structure.

[0083] In the above structure, the retraction and expansion of the mounting bracket 12 are achieved through the stretching and nesting of the upper bracket 121 and the middle bracket 122, and the stretching and nesting of the lower bracket 123 and the middle bracket 122. This structure of stretching and retracting of the mounting bracket 12 facilitates the retraction and expansion of the mounting bracket 12 and the outdoor unit body 10. Since the top end of the upper bracket 121 is connected to the top cover 114, which is located on the upper housing 111, and the bottom end of the lower bracket 123 is connected to the chassis 115, which is located on the lower housing 113, the stretching and retraction of the mounting bracket 12 is synchronized with the stretching and retraction of the outdoor unit housing 11. Furthermore, it facilitates the installation of other structures (e.g., the outdoor unit heat exchanger 13) and other components of the outdoor unit body 10, thereby reducing modifications to the internal structure of the air conditioner outdoor unit and ensuring the stability and performance of the air conditioner outdoor unit.

[0084] Furthermore, in this embodiment, the outdoor unit body 10 also includes an outdoor unit heat exchanger 13, which includes an upper heat exchanger 131 and a lower heat exchanger 132.

[0085] The upper heat exchanger 131 is mounted on the upper bracket 121, and the lower heat exchanger 132 is mounted on the lower bracket 123, with the lower heat exchanger 132 and the upper heat exchanger 131 being offset from each other.

[0086] Understandably, the lower heat exchanger 132 and the upper heat exchanger 131 are offset from each other, that is, the positions of the lower heat exchanger 132 and the upper heat exchanger 131 are offset from each other. In this embodiment, the positions of the lower heat exchanger 132 and the upper heat exchanger 131 are offset from each other in the vertical direction.

[0087] In the above structure, the lower heat exchanger 132 and the upper heat exchanger 131 are staggered, which facilitates the installation of the outdoor unit heat exchanger 13 on the outdoor unit body 10. Furthermore, the upper heat exchanger 131 is installed on the upper bracket 121, and the lower heat exchanger 132 is installed on the lower bracket 123. When the mounting bracket 12 is stretched or contracted, because the upper heat exchanger 131 is installed on the upper bracket 121 and the lower heat exchanger 132 is installed 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. This facilitates the contraction and expansion of the outdoor unit heat exchanger 13 and the outdoor unit body 10.

[0088] Example 3

[0089] See Figures 1 to 7 Based on the above embodiment one or embodiment two, the outdoor unit of the air conditioner in this embodiment includes a fan blade 20 comprising a fan hub 21 and multiple fan blades 22.

[0090] The impeller hub 21 is located in the outdoor unit body 10, and multiple impeller blades 22 are located on the impeller hub 21. Each impeller blade 22 is foldable.

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

[0092] In this embodiment, three wind turbine blades 22 are provided. It can be understood that in other embodiments, the number of wind turbine blades 22 may also be set to other quantities, for example, five wind turbine blades 22 may also be set.

[0093] In this embodiment, when the fan blades 22 are in a folded state, the outdoor unit fan blades 20 are in a folded state; correspondingly, when the fan blades 22 are in an unfolded state, the outdoor unit fan blades 20 are in an unfolded state.

[0094] In the above structure, the folding and unfolding of the outdoor unit fan blades 20 is achieved by folding and unfolding multiple fan blades 22. This makes it easier to fold and unfold the outdoor unit fan blades 20, and makes better use of the internal space in the outdoor unit body 10. It also facilitates the unfolding of the outdoor unit fan blades 20 when the outdoor unit is installed or used.

[0095] Furthermore, in this embodiment, the outdoor unit body 10 is provided with a fan blade drive component 31, and the fan blade hub 21 is disposed on the fan blade drive component 31.

[0096] Specifically, based on Embodiment 2, the fan blade drive component 31 is mounted on the intermediate support 122, and the rotation of the fan blade hub 21 is driven by the fan blade drive component 31.

[0097] For example, the fan blade drive component 31 is a fan blade drive motor.

[0098] Example 4

[0099] See Figures 1 to 7 Based on the above embodiment three, in this embodiment of the air conditioner outdoor unit, each fan blade 22 includes a first blade 221 and a second blade 222.

[0100] The first blade 221 is mounted on the impeller hub 21, and a blade shaft 223 is mounted on one side of the first blade 221.

[0101] The second blade 222 is adapted to the first blade 221. The second blade 222 is rotatably connected to the first blade 221 through the blade shaft 223, so that the wind turbine blade 22 can be folded or unfolded.

[0102] In this embodiment, the first blade 221 is fixedly mounted on the impeller hub 21, and the second blade 222 is rotatably connected to the first blade 221 via the blade shaft 223. When the outdoor unit of the air conditioner is in use, the second blade 222 can gradually unfold relative to the first blade 221 as the impeller hub 21 and the first blade 221 rotate, until it is fully unfolded and returns to its normal form for use.

[0103] In the above structure, the second blade 222 is rotatably connected to the first blade 221 via the blade shaft 223, so that the fan blade 22 can be folded or unfolded. With this structure, when the outdoor unit of the air conditioner is in use, the multiple fan blades 22 of the outdoor unit fan blade 20 can unfold with the rotation of the fan hub 21 and return to the normal shape of the fan blade 22, ensuring the normal use of the outdoor unit fan blade 20. This facilitates the installation of the outdoor unit of the air conditioner, eliminating the need for the staff to open the outdoor unit of the air conditioner to adjust the shape of the fan blades 22 during installation.

[0104] Specifically, in this embodiment, a rotation limiting part (not shown in the figure) is provided on the blade shaft 223, which is used to limit the rotation angle of the second blade 222.

[0105] In the above structure, the rotation limiter can limit the rotation angle of the second blade 222, so that the fan blade 22 unfolds to a specific shape as the fan hub 21 rotates, and maintains this specific shape in the future, avoiding the continuous switching of the shape of the fan blade 22, ensuring the quality of the fan blade 22 and the outdoor unit fan blade 20, and thus ensuring the quality of use and product performance of the air conditioner outdoor unit.

[0106] Example 5

[0107] See Figures 1 to 7 This application provides an air conditioning device, including an outdoor unit of an air conditioner from any of the embodiments one to four described above.

[0108] For example, the air conditioning equipment can be a wall-mounted air conditioning unit or a floor-standing air conditioning unit, etc.

[0109] The air conditioning equipment in this application embodiment uses an outdoor air conditioning unit from any of the embodiments one to four above. During transportation, the outdoor air conditioning unit can be reduced to a smaller size, reducing the space it occupies during transportation and freeing up more space for indoor wall-mounted units. This increases the number of wall-mounted air conditioning units that can be transported by the transport vehicle, reduces the waste of transport space, and lowers the transportation cost of the wall-mounted air conditioning units.
