In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples.

In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize the applicability of other processes and/or the use of other materials.

Next, a window air conditioner 100 according to an embodiment of the present invention is described with reference to the accompanying drawings.

As shown in fig. 1 and 2, the window air conditioner 100 includes: the window type air conditioner 100 has a use form in which the inner unit body 1 can be positioned on the indoor side and the outer unit body 2 can be positioned on the outdoor side, so that the window type air conditioner 100 has the use form in which the inner unit body 101 and the outer unit body 102 are longitudinally spaced apart from the inner unit body 1, and the inner unit body 101 and the outer unit body 102 include the inner unit body 1 and the outer unit body 2. It should be noted that, the window-type air conditioner 100 described herein is suitable for being disposed in the window 200, the inside-outside direction of the window 200 (i.e., the direction penetrating the window 200) is "longitudinal", the width direction of the window 200 is "transverse", and the height direction of the window 200 is "vertical".

Briefly, according to the window air conditioner 100 of the embodiment of the present invention, the inner unit 101 includes the inner unit body 1 adapted to be disposed at the indoor side, the outer unit 102 includes the outer unit body 2 adapted to be disposed at the outdoor side, and when the window air conditioner 100 is in the use configuration (for example, the configuration shown in fig. 1 and 2), the inner unit body 1 is spaced apart from the outer unit body 2 in the inner and outer directions, the inner unit body 1 is disposed at the indoor side for adjusting the indoor environment temperature or the like, and the outer unit body 2 is disposed at the outdoor side for exchanging heat with the outdoor environment.

For example, in some alternative examples, the inner unit body 1 may include an indoor side heat exchanger, an indoor side fan, etc., and the outer unit body 2 may include a compressor, an outdoor side heat exchanger, an outdoor side fan, etc., and a refrigerant pipe is connected between the inner unit body 1 and the outer unit body 2, so that the indoor side heat exchanger, the outdoor side heat exchanger, the compressor, etc. constitute a refrigerant circulation system to implement a refrigeration cycle or a heating cycle. Of course, the present invention is not limited thereto, and for example, in other embodiments of the present invention, an indoor side fan, an outdoor side fan, etc. may be omitted, which is not exemplified herein.

As shown in fig. 1, the inner unit part 101 is rotatably connected with the outer unit part 102) such that one of the outer unit part 102 and the inner unit part 101 is rotatable with respect to the other about a rotation axis L extending in a lateral direction to change the configuration of the window air conditioner 100. The term "lateral direction" as used herein, in which the rotation axis L extends in the lateral direction, refers to the lateral direction when the window air conditioner 100 is in the use configuration.

Thus, when one of the outer machine part 102 and the inner machine part 101 is used as a rotating part and the other is used as a static part, when the form of the window air conditioner 100 needs to be changed, the rotating part can be forced to rotate around the rotation axis L relative to the static part, so that the form of the window air conditioner 100 can be changed to meet different requirements. For example, the window air conditioner 100 may be configured to meet the installation requirement, the transportation requirement, the packaging requirement, the transportation requirement, or the like of the window air conditioner 100 by changing the configuration of the window air conditioner 100, so that the window air conditioner 100 may be configured to flexibly change the configuration (e.g., to the configuration shown in fig. 3 or 4) without being limited by the usage configuration (e.g., the configuration shown in fig. 1 and 2) of the window air conditioner 100 in the installation, the transportation, the packaging, the transportation, or the like.

In some embodiments, the inner machine part 101 is pivotally connected to the outer machine part 102 such that the axis of rotation L about which the outer machine part 102 and the inner machine part 101 rotate relative to each other is uniquely defined, and there are no multiple axes of rotation or otherwise, so that it can be ensured that the locus of rotation of the rotating part relative to the stationary part is defined. Therefore, when the form of the window air conditioner 100 needs to be changed, the rotating component can rotate around the uniquely determined rotation axis L relative to the static component, so that the rotation track of the rotating component is unique and determined, the rotating component rotates stably and is supported reliably (namely, the unique rotation axis L is used as a support), the window air conditioner 100 can be further ensured to reliably change the form, and the rotation of the rotating component is driven to be simple, smooth and labor-saving. For example, in some alternative examples, the inner machine member 101 and the outer machine member 102 may be pivotally connected by a pivot mechanism such as a hinge assembly 106, a bearing, a shaft, or the like.

It should be noted that, if the movable connection of at least one link is replaced with the pivotal connection about the single rotation axis L, there are at least two rotation axes, and when the rotation member rotates relative to the stationary member, the movement locus of the rotation member is uncertain, so that the operation of driving the rotation member to rotate is difficult and difficult to control. And if there are a plurality of rotation axes, it is difficult to perform reliable and efficient rotation support of the rotation member by the rotation position, for example, by connecting the inner machine member and the outer machine member by a link whose both ends are rotatable, and it is difficult for the link to form reliable support for the rotation member, thereby resulting in more effort to drive the rotation member to move.

In some embodiments, the outer machine body 2 is reciprocally rotatable relative to the axis of rotation L between a first state (e.g., the state shown in fig. 1 and 2) and a second state (e.g., the state shown in fig. 3 and 4). As shown in fig. 1 and 2, in the first state, the back plate of the outer machine body 2 (i.e., the first back plate 21) is vertically arranged, and the rotation axis L is located at a height position of the back plate upper portion of the outer machine body 2 (but the longitudinal position of the rotation axis L is not limited). As shown in fig. 3 and 4, in the second state, the back plate of the outer machine body 2 (i.e., the first back plate 21) is placed horizontally so as to serve as the bottom wall of the outer machine body 2.

It should be noted that "vertical" as used herein is vertical or substantially vertical, and "horizontal" is horizontal or substantially horizontal, as broadly understood. In addition, it should be noted that, when the window air conditioner 100 is in the use configuration, the back plate of the outer unit body 2 (i.e., the first back plate 21) refers to a side structure of the outer unit body 2 facing the wall at the window, for example, when the outer unit body 2 is in a closed structure, the first back plate 21 may be a side wall surface of the housing of the outer unit body 2, and for example, when the outer unit body 2 is in a semi-open structure, the first back plate 21 may also be a side wall surface of the condenser.

It should be noted that the phrase "the outer machine body 2 is reciprocally rotatable between the first state and the second state with respect to the rotation axis L" is intended to describe that the outer machine body 2 has the capability of switching the two states by rotation, but is not limited to the fact that the switching between the two states must be achieved by driving the rotation of the outer machine body 2, and for example, when the switching between the states of the outer machine body 2 is required, the switching may be achieved by driving the rotation of the outer machine member 102 or the rotation of the inner machine member 101, which falls within the scope of the present application.

For example, when the window air conditioner 100 assumes a use configuration (e.g., as shown in fig. 1 and 2), the exterior body 2 may be changed to the first state. When the window air conditioner 100 needs to be changed to the installation configuration (for example, as shown in fig. 3 and 4), the exterior body 2 may be changed to the second state. In addition, when the window air conditioner 100 is switched between the use mode and the installation mode, the position and the mode of the indoor unit body 1 may be changed or may not be changed, and the present application is not limited thereto.

It will be appreciated that the vertical height position of the rotation axis L may be maintained regardless of whether the outer machine body 2 is in the first state or the second state, and the rotation axis L is located at an upper height position of the outer machine body 2 when the outer machine body 2 assumes the first state, and corresponds to a lower height position of the outer machine body 2 because the back plate of the outer machine body 2 is lifted to a horizontal state when the outer machine body 2 assumes the second state.

That is, it corresponds to substantially: when the outer machine body 2 presents the first state, the whole outer machine body 2 is generally lower than the horizontal plane of the rotation axis L, and when the outer machine body 2 presents the second state, the whole outer machine body 2 is generally higher than the horizontal plane of the rotation axis L. For example, the exterior body 2 may be turned upward by the bottom elevation (counterclockwise rotation as shown in fig. 3), so that the exterior body 2 is changed from the first state (the state shown in fig. 1 and 2) to the second state (the state shown in fig. 3 and 4).

Therefore, when the outer machine body 2 is changed from the first state to the second state, the whole outer machine body 2 is lifted relative to the rotation axis L, so that the outer machine body 2 can be easily pushed out from the window 200 from the indoor side to the outdoor side, the installation difficulty of the window type air conditioner 100 can be reduced, and the window type air conditioner 100 can be installed more labor-effectively. That is, the operation of pushing out the exterior body 2 from the inside to the outside by raising the window air conditioner 100 as a whole so that the bottom wall of the exterior body 2 exceeds the sill height is avoided, thereby making the operation more labor-saving. Moreover, since the window air conditioner 100 is not required to be integrally lifted and the outer machine body 2 is pushed out, the risk that the whole machine is inclined and falls to the outside due to the fact that the gravity center of the whole machine is high and difficult to control when the whole machine is pushed out from inside to outside is avoided, and therefore the installation safety is improved.

For example, as shown in fig. 1 and 2, when the window air conditioner 100 is in the use configuration, the inner unit body 1 is spaced apart from the outer unit body 2 in the inward-outward direction, the bottom plate (i.e., the second bottom plate 12) of the inner unit body 1 is downward, the top plate (i.e., the second top plate 13) is upward, the panel (i.e., the second panel 14) is inward, and the back plate (i.e., the second back plate 11) is outward. The bottom plate (i.e., the first bottom plate 22) of the outer machine body 2 is downward, the top plate (i.e., the first top plate 23) is upward, the face plate (i.e., the first face plate 24) is outward, the back plate (i.e., the first back plate 21) is inward, and the upper inner end of the outer machine member 102 is pivotally connected to the upper outer end of the inner machine member 101.

For example, as shown in fig. 3 and 4, if the outer machine member 102 is pulled upward to pivot the outer machine member 102 in a counterclockwise direction about the rotation axis L, the window air conditioner 100 assumes an installed configuration when the outer machine member 102 is rotated 90 °, with the bottom plate (i.e., the first bottom plate 22) of the outer machine body 2 facing the outdoor side, the top plate (i.e., the first top plate 23) facing the indoor side, the front plate (i.e., the first front plate 24) facing upward, and the rear plate (i.e., the first rear plate 21) facing downward. The inner machine body 1 still keeps the bottom plate (i.e., the second bottom plate 12) downward, the top plate (i.e., the second top plate 13) upward, the panel (i.e., the second panel 14) toward the indoor side, and the back plate (i.e., the second back plate 11) toward the outdoor side.

For example, as shown in fig. 5, if the inner unit 101 is pulled upward to pivot the inner unit 101 in a clockwise direction about the rotation axis L, the window air conditioner 100 is in an intermediate state when the inner unit 101 is rotated 90 °, the bottom plate (i.e., the second bottom plate 12) of the inner unit body 1 faces the indoor side, the top plate (i.e., the second top plate 13) faces the outdoor side, the panel (i.e., the second panel 14) faces upward, and the back plate (i.e., the second back plate 11) faces downward. The outer machine body 2 still keeps the bottom plate (i.e., the first bottom plate 22) downward, the top plate (i.e., the first top plate 23) upward, the face plate (i.e., the first face plate 24) outward, and the back plate (i.e., the first back plate 21) inward. It will be appreciated that the window air conditioner 100 (shown in fig. 5) in its intermediate configuration is rotated 90 ° counterclockwise as a whole, and the window air conditioner 100 may assume its installed configuration (e.g., as shown in fig. 3).

To sum up, as shown in fig. 1 and 2, when the window air conditioner 100 is in the use form, the rotation axis L is located at the upper height position of the outer machine body 2, as shown in fig. 3 and 4, when the window air conditioner 100 is in the installation form, the rotation axis L is located at the lower height position of the outer machine body 2, and since the vertical height of the rotation axis L is unchanged, the whole outer machine body 2 is lifted up, so that the outer machine body 2 can be easily pushed out from the indoor side to the outdoor side through the window 200 under the condition that the state of the inner machine body 1 is unchanged, the installation difficulty of the window air conditioner 100 is reduced, the installation of the window air conditioner 100 is more labor-saving, the control is easy, and the risk that the whole air conditioner falls sideways outdoors is reduced.

It will be appreciated that if the window air conditioner 100 is maintained in the use state all the time, the window air conditioner 100 needs to be lifted up as a whole when the outer machine body 2 needs to be pushed out from the window 200, and the operation is laborious. Moreover, if the window air conditioner 100 is always kept in the usage mode, when the whole machine is lifted to push out the whole machine, the whole machine is slightly higher in gravity center due to the fact that the height of the inner machine part 101 is also higher (for example, higher than the bottom edge height of the window 200), so that the problem that the outer machine body 2 is inclined outwards is solved, and the control is difficult, and the danger is caused.

In the window-type air conditioner 100 according to some embodiments of the present invention, since the inner unit 101 can be maintained at the height of the usage mode, for example, lower than the bottom edge of the window 200, the installer can easily press the inner unit 1 from the top of the inner unit 1, thereby avoiding the problem that the outer unit 2 falls down and falls down, and being easy to control and reduce the risk.

As described above, the window air conditioner 100 is changed from the use mode to the installation mode in various ways. For example, as shown in fig. 1 and 3, the exterior body 2 may be rotated from the first state to the second state by rotating 90 ° counterclockwise about the rotation axis L, so that the window air conditioner 100 is changed from the use configuration to the installation configuration. Alternatively, as shown in fig. 1 and 5, for example, the indoor unit body 1 may be turned 90 ° clockwise about the rotation axis L to turn the window air conditioner 100 into an intermediate configuration, and then turning the whole unit counterclockwise by 90 ° in conjunction with fig. 3 and 5 to turn the window air conditioner 100 from the intermediate configuration into an installation configuration (for example, the configuration shown in fig. 3).

In some embodiments, as shown in fig. 1 and 2, the inner machine part 101 includes a connection bracket 3 adapted to be inserted through the window 200, and an outer end of the connection bracket 3 extends to be pivotally connected to an upper inner end of the outer machine body 2, so that the rotation axis L is located at a junction position of a back plate (i.e., the first back plate 21) and a top plate (i.e., the first top plate 23) of the outer machine body 2 (i.e., a position near an indoor side of an upper portion of the outer machine body 2 in a use configuration of the window air conditioner 100).

It should be noted that the phrase "the outer end of the connection bracket 3 extends to be pivotally connected to the upper inner end of the outer machine body 2" is intended to describe a position where the inner machine component 101 is connected to the outer machine body 2, and is not limited to a position where connection is achieved, and may be, for example, direct connection or indirect connection, and the position where the linking member used for indirect connection is provided is not limited, and may be, for example, provided in the connection bracket 3 or provided in the inner machine body 1..

Therefore, since the inner machine part 101 comprises the connecting bracket 3 which can pass through the window 200 and is pivotally connected with the outer machine body 2, the rotation axis L can be positioned at the upper inner end of the outer machine body 2 (namely, at the junction position of the back plate and the top plate of the outer machine body 2), when the inner machine part 101 is used as a static part and the outer machine part 102 is rotated, the inner machine part 101 is equivalent to the rotation axis L which is only positioned at the upper inner end position of the outer machine body 2, so that the position of the rotation axis L can be used as a reliable rotation support, the pivoting stability and reliability of the outer machine body 2 are improved, the whole rotation sweeping space range of the outer machine part 102 can be reduced, the driving moment required for driving the outer machine part 102 to rotate is reduced, the operation is more labor-saving, and the opening height requirement of the window 200 is lower (for example, the window 200 is lower).

It should be noted that the connection relationship between the inner machine body 1 and the connection bracket 3 is not limited, and may be, for example, a fixed connection or a sliding connection that is relatively movable in the longitudinal direction, and the like, which is not limited herein. When the inner machine body 1 is fixedly connected with the connecting bracket 3, at least part of the connecting bracket 3 is always positioned on the outer side of the inner machine body 1, so that the outer machine body 2 is longitudinally spaced from the inner machine body 1. When the inner unit body 1 and the connecting bracket 3 are connected in a sliding manner in the longitudinal direction, and the window air conditioner 100 is in a use mode, at least part of the connecting bracket 3 is positioned outside the inner unit body 1, so that the outer unit body 2 is spaced apart from the inner unit body 1 in the longitudinal direction. When the inner unit body 1 and the connection bracket 3 are slidably connected in the longitudinal direction, and the window air conditioner 100 is in the installed configuration, the connection bracket 3 may be stacked on the upper portion of the inner unit body 1 so that the inner unit part 1 and the outer unit part 2 are in a state of being adjacent to each other, or at least a portion of the connection bracket 3 may be located on the outer side of the inner unit body 1 so that the inner unit body 1 and the outer unit body 2 are spaced apart in the longitudinal direction.

When the inner machine body 1 and the connecting support 3 are in sliding connection capable of moving relatively along the longitudinal direction, the relative longitudinal positions of the outer machine body 2 and the inner machine body 1 can be adjusted, so that the longitudinal distance between the outer machine body 2 and the inner machine body 1 is reduced, packaging and transportation are facilitated, and the longitudinal interval distance between the outer machine body 2 and the inner machine body 1 can be matched with the longitudinal size requirements of different windowsills.

Of course, the invention is not limited thereto, and for example, in other embodiments of the invention, instead of the connecting bracket 3, a first bracket and a second bracket may be employed, wherein the inner machine part 101 comprises a first bracket that can extend into the window 200 from inside to outside, the outer machine part 102 comprises a second bracket that can extend into the window 200 from outside to inside, and an outer end (i.e., an end near the outside of the room) of the first bracket is pivotally connected to an inner end (i.e., an end near the inside of the room) of the second bracket (this embodiment is not shown). At this time, when the inner machine part 101 is used as a stationary part and the outer machine part 102 is rotated, the outer machine body 2 and the second bracket rotate together around the rotation axis L, the space range swept by the whole rotation of the outer machine part 102 is relatively large, the driving torque required for driving the outer machine part 102 to rotate is large, and the requirement on the opening height of the window 200 is slightly high (for example, the height of the window 200 needs to be slightly high).

Alternatively, in other embodiments of the present invention, instead of the connection bracket 3, a third bracket may be used, where the outer unit 102 includes a third bracket adapted to be disposed through the window 200, and an inner end (i.e., an end near the indoor side) of the third bracket is pivotally connected to an upper outer end of the inner unit body 1 (i.e., an end near the outdoor side of the upper portion of the inner unit body 1 in the use configuration of the window air conditioner 100) (this embodiment is not shown). At this time, when the inner machine part 101 is used as a stationary part and the outer machine part 102 is rotated, the outer machine body 2 and the third bracket rotate together around the rotation axis L, the space range swept by the whole rotation of the outer machine part 102 is larger, the driving torque required for driving the rotation of the outer machine part 102 is larger, and the requirement on the opening height of the window 200 is higher (for example, the window 200 is higher, especially, the longitudinal dimension of the window 200 is larger, the opening height of the window 200 is higher).

In addition, when the inner machine part 101 includes the connecting bracket 3, the outer end of the connecting bracket 3 is pivotally connected with the upper inner end of the outer machine body 2, compared with the scheme that the outer machine part 102 also includes a bracket section (such as the second bracket or the third bracket), when the outer machine part 102 is rotated, the outer machine body 2 is prevented from applying force to the bracket section (such as the second bracket or the third bracket), so that hidden troubles of compression damage, fracture and the like of the bracket section are caused, and the structural reliability can be improved at low cost. In addition, when the outer machine part 102 does not include a bracket section, the structure of the outer machine part 102 can be simplified, the cost can be reduced, and the assembly can be simplified.

In some embodiments, as shown in fig. 6, when the outer machine body 2 assumes the second state, the back plate of the outer machine body 2 (i.e., the first back plate 21) is flush with the bottom plate of the connection bracket 3. It should be noted that "flush" herein may be completely flush, or substantially flush. Therefore, when the outer machine body 2 is pushed from the indoor side to the outdoor side, in the process that the outer machine body 2 passes through the window 200, the window type air conditioner 100 is almost free from moving in the vertical direction, and the connecting support 3 can immediately penetrate into the window 200 after the outer machine body 2, so that the operation is simplified, the operation is more labor-saving and convenient, and the assembly efficiency is higher.

In some embodiments, as shown in fig. 6-8, the back plate (i.e., the first back plate 21) of the outer machine body 2 has a first guiding structure 25 thereon, and the first guiding structure 25 is adapted to cooperate with a guide rail 301 mounted on a mounting bracket 300 of the window 200, so as to implement push-pull guiding of the outer machine body 2 in the second state along the inner and outer directions. Thus, when the window air conditioner 100 is in the installed state, the outer machine body 2 can be smoothly pushed out from the indoor side to the outdoor side with a reduced effort by the engagement of the first guide structure 25 and the guide rail 301.

Further, referring to fig. 6, 7 and 9, the bottom of the connecting bracket 3 has a second guiding structure 31, and the second guiding structure 31 is adapted to mate with the guide rail 301 after the first guiding structure 25. That is, when the window type air conditioner 100 assumes the installation form, the outer machine body 2 can be smoothly and laborsaving pushed out from the indoor side to the outdoor side by using the cooperation of the first guide structure 25 and the guide rail 301, then the connecting bracket 3 can be pushed into the window 200 by using the cooperation of the second guide structure 31 and the guide rail 301, in this process, the whole window type air conditioner 100 does not need to move vertically, and the connecting bracket 3 can immediately follow the outer machine body 2 to penetrate into the window 200, so that the operation is simplified, the operation is more laborsaving and convenient, and the assembly efficiency is higher. The shapes of the first guide structure 25, the second guide structure 31, and the guide rail 301 are not limited, and may be, for example, long strip shapes, etc., as long as the guide requirements can be satisfied well.

In short, the second guide structure 31 and the first guide structure 25 are respectively disposed at the bottom of the connection bracket 3 and the back plate of the outer unit body 2, and meanwhile, the guide rail 301 is disposed on the installation bracket 300, the window air conditioner 100 is transformed into the installation configuration, and the inner unit body 1 and the outer unit body 2 are longitudinally spaced apart and connected through the connection bracket 3, at this time, the window air conditioner 100 is placed on the installation bracket 300, so that the first guide structure 25 at the bottom of the outer unit body 2 is matched with the guide rail 301, the window air conditioner 100 is pushed outwards along the guide of the guide rail 301, the matched part of the first guide structure 25 and the guide rail 301 is reduced as the whole unit moves outwards, the second guide structure 31 gradually enters into the matched part with the guide rail 301, and the matched part of the second guide structure 31 and the guide rail 301 is increased, thereby ensuring the reliable matched between the whole unit and the installation bracket 300. When the outer machine body 1 is completely extended to the outside of the window 200, the first guide structure 25 is separated from the guide rail 301, and the second guide structure 31 is still matched with the guide rail 301, so that the whole machine is reliably matched with the mounting bracket 300. After that, the outer machine body 1 can be turned downward so that the outer machine body 1 is shifted to the first state satisfying the use requirement.

In some embodiments of the present invention, the back plate of the outer machine body 2 (i.e. the first back plate 21) may further have two reinforcing rails, which are separately disposed on two lateral sides of the back plate of the outer machine body 2, and all the first guide structures 25 are located between the two reinforcing rails, where when the outer machine body 2 assumes the second state, the two reinforcing rails are sandwiched on two lateral sides of the mounting bracket 300 or cooperate with guide structures disposed at corresponding positions on the mounting bracket 300, so as to further perform a guiding function.

In some embodiments of the present invention, the window air conditioner 100 may include a first limit structure 104 (in conjunction with fig. 10 and 11), the first limit structure 104 being adapted to prevent the outer machine body 2 from continuing to rotate in a current rotational direction (e.g., prevent the outer machine body 2 from rotating in a counterclockwise direction as shown in fig. 3) when the outer machine body 2 rotates to a second state (e.g., the state shown in fig. 3) relative to the inner machine part 101. Therefore, an installer can easily change the outer machine body 2 to the second state, the operation is simplified, and the assembly efficiency is improved.

The structure and the installation position of the first limiting structure 104 are not limited, as long as the above-described limitation can be achieved. For example, as shown in fig. 10 and 11, when the inner machine part 101 is pivotally connected to the outer machine part 102 through the hinge assembly 106, the first limiting structure 104 may be integrated with the hinge assembly 106, for example, the hinge assembly 106 may include a first hinge member 41 and a second hinge member 42 that rotate relatively, a first stop portion 411 is disposed on the first hinge member 41, and a second stop portion 421 is disposed on the second hinge member 42, and when the outer machine body 2 rotates from the first state to the second state, the first stop portion 411 and the second stop portion 421 are in stop fit to prevent the outer machine body 2 from continuing to rotate along the current rotation direction.

For another example, referring to fig. 11, the first limiting structure 104 may be further divided into a first substructure 1041 disposed on the inner machine component 101 and a second substructure 1042 disposed on the outer machine component 102, where when the outer machine body 2 rotates to the second state relative to the inner machine component 101, the first substructure 1041 and the second substructure 1042 are in stop fit, so as to prevent the outer machine body 2 from continuing to rotate along the current rotation direction, and so on.

In some embodiments of the present invention, as shown in fig. 12, the window air conditioner 100 may include a second limit structure 105, the second limit structure 105 being adapted to prevent the outer machine body 2 from reversing toward the direction of returning to the first state (e.g., prevent the outer machine body 2 from rotating in a clockwise direction as shown in fig. 12) when the outer machine body 2 rotates to the second state relative to the inner machine member 101. Therefore, the outer machine body 2 can be stably kept in the second state, and the installation is convenient.

The structure and the installation position of the second limiting structure 105 are not limited, as long as the above-described limitation can be achieved. For example, in some embodiments, as shown in fig. 13 and 14, the second limiting structure 105 is in the form of a buckle and includes a first buckle element 61 and a second buckle element 62, the first buckle element 61 is provided on the inner machine part 101, the second buckle element 62 is provided on the outer machine part 102, when the outer machine body 2 assumes the second state (for example, the state shown in fig. 12 and 13), the first buckle element 61 and the second buckle element 62 can be locked by the buckle, the second limiting structure 105 prevents the outer machine body 2 from reversing in a direction to recover the first state, and when the first buckle element 61 and the second buckle element 62 are separated and unlocked, the outer machine body 2 can reversing in a direction to recover the first state from the second state to switch back to the first state (for example, to the state shown in fig. 1 and 14). Thus, the second limiting structure 105 is simple, facilitating the position locking.

Alternatively, as shown in fig. 12 to 14, the second limiting structure 105 in the form of a snap may be two and separately disposed on two lateral sides of the outer machine member 102, and when the outer machine member 102 is in the first state (as shown in fig. 1 and 14), the first snap 61 is connected to a portion of the upper portion of the inner machine member 101 near the back plate of the inner machine body 1 (i.e., the second back plate 11), and extends obliquely upward from the indoor side to the outdoor side, and the second snap 62 is connected to a portion of the upper portion of the outer machine member 102 near the back plate of the outer machine body 2 (i.e., the first back plate 21), and extends obliquely upward from the outdoor side to the indoor side. When the outer machine part 102 rotates to the second state (as shown in fig. 12 and 13), the second fastening member 62 rotates to be connected with the first fastening member 61 in a straight line and is hooked, so that triangular supporting limit is formed with the outer machine part 102 and the inner machine part 101, and a relatively stable limit is formed.

For example, in some embodiments, as shown in fig. 15, the second limiting structure 105 may further include a pull rod 71 and a sliding groove 72, where the sliding groove 72 extends longitudinally and is formed on the inner machine part 101, the inner end of the sliding groove 72 has an upwardly extending detent slot 73, two ends of the pull rod 71 are a first end 711 and a second end 712, respectively, the first end 711 is rotatably connected with the outer machine body 2, the second end 712 cooperates with the sliding groove 72 to be slidable along the sliding groove 72, and when the second end 712 cooperates with the detent slot 73, the second limiting structure 105 may prevent the outer machine body 2 from reversing in a direction of returning to the first state (for example, prevent the outer machine body 2 shown in fig. 16 from rotating in a clockwise direction). Thus, the second limiting structure 105 is simple, facilitating the position locking.

Alternatively, as shown in fig. 15 and 16, the tie rod 71 may be two and separately disposed on both lateral sides of the outer machine member 102, and as shown in fig. 15, the first end 711 of the tie rod 71 is connected to a portion of the upper portion of the outer machine member 102 near the panel (i.e., the first panel 24) when the outer machine member 102 is in the first state. As shown in fig. 16, when the outer machine part 102 rotates to the second state, the second end 712 of the pull rod 71 may slide toward the indoor side and enter the clamping groove 73, at this time, the connection between the pull rod 71 and the outer machine part 102 and the connection between the pull rod 71 and the inner machine part 101 may form a triangle, so as to form a relatively stable limit, and the outer machine part 102 may not slide toward the outdoor side along the sliding groove 72 even if the outer machine part 102 has a downward rotation tendency under the action of gravity, so as to prevent the outer machine part 102 from rotating toward the first state shown in fig. 15.

Further, in conjunction with fig. 17, the second limiting structure 105 may further include a return spring 74, where the return spring 74 is connected between the inner machine part 101 and the second end 712 to apply an elastic force to the second end 712 that moves toward the detent groove 73. Thus, when the outer machine member 102 is rotated from the second state to the first state, the return spring 74 can be extended to provide a cushioning effect to some extent. When the second end 712 of the pull rod 71 enters the locking groove 73, the pull rod 71 can be forced by the return spring 74, so that a more stable limit is formed and the outer machine part 102 is prevented from turning upside down.

In some embodiments of the present invention, the outer end of the connection bracket 3 and the outer machine body 2 may be pivotally connected by a hinge assembly 106. The type of the hinge assembly 106 is not limited, and in some embodiments, for example, as shown in fig. 18 and 19, the hinge assembly 106 may be an exposed hinge a, and at least a portion of the exposed hinge a may be exposed outside the top wall or the bottom wall of the connection bracket 3. Thereby, the installation and inspection of the exposed hinge a can be simplified. The hinge assembly 106 may also be a built-in hinge b, as shown for example in fig. 10 and 11, which is not exposed outside the top wall or outside the bottom wall of the connecting bracket 3. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the inner machine part 101 and the outer machine part 102 may be pivotally connected by other manners, such as through bearings or a shaft connection, etc., which are not described herein.

In some embodiments of the present invention, as shown in fig. 10 and 11, the hinge assembly 106 may include a first hinge member 41 provided to the inner machine part 1 and a second hinge member 42 provided to the outer machine part 2, which are hingedly connected, and in some embodiments, the first hinge member 41 and the second hinge member 42 may be pivotally connected by a damping hinge shaft 43. For example, the damping rotating shaft 43 may adopt a spring washer, and the rotating moment may be adjusted as required, so as to solve the problem that the outer machine body 2 drops rapidly when rotating, and the damping rotating shaft 43 has a strong enough structure to effectively support the outer machine body 2 to rotate.

In some embodiments of the present invention, as shown in fig. 19-21, the outer machine body 2 has a grip groove 26 thereon, and the grip groove 26 is located on at least one of the lateral side plate (i.e., the first side plate 20), the top plate (i.e., the first top plate 23), and the back plate (i.e., the first back plate 21) of the outer machine body 2. That is, a groove-shaped structure may be formed on the outer machine body 2 as the catch groove 26, thereby facilitating the rotation of the outer machine body 2. It should be noted that, in order to reduce the noise influence of the window air conditioner 100 on the indoor environment, the compressor may be disposed in the outer machine body 2, so that the weight of the outer machine body 2 is relatively heavy, and by disposing the buckling groove 26, the installer may stably and reliably operate the outer machine body 2 to rotate, so as to avoid the problem of hand sliding.

For example, as shown in fig. 20 and 21, the number of the catch grooves 26 is two and located at positions on the lateral sides of the outer machine body 2, and for example, as shown in fig. 19, the number of the catch grooves 26 is two and located on the back plate (i.e., the first back plate 21) and spaced apart in the lateral direction, thereby facilitating the operation of the outer machine body 2 to rotate by gripping the catch grooves 26, and thus facilitating the manual change of the form of the window air conditioner 100.

Alternatively, the width of the clasp gap 26 may be more than 800mm, so as to be ergonomic, ensuring a greater width than the palm, so that the machine can be effectively lifted.

In an embodiment of the present invention, as shown in fig. 20, the window air conditioner 100 may further include a support assembly 108, wherein the support assembly 108 is movably disposed between the connection bracket 3 and the outer casing body 2, and is used for preventing (not preventing) the outer casing body 2 from performing the bottom-lowering overturning motion. For example, when the outer casing 2 is rotated downward (e.g., rotated clockwise as shown in fig. 20) with respect to the inner casing 101 with the bottom lowered, the outer casing 2 is provided with resistance to the rotation in this direction to buffer the downward rotation of the outer casing 2, avoiding the problem of the outer casing 2 being bumped or dropped by the rapid downward rotation, and improving the reliability and safety of the installation. For example, when the outer machine body 2 is turned upwards, the outer machine body 2 is blocked to a certain extent by the action of the supporting component 108, so that the operation of an installer can be more labor-saving, and the operation difficulty is reduced.

For example, as shown in fig. 20, the support assembly 108 may include a first support member 81 and a second support member 82 that can slide relatively, an energy storage medium is provided between the first support member 81 and the second support member 82, one end of the length of the first support member 81 away from the second support member 82 is rotatably connected with the connection bracket 3, and one end of the length of the second support member 82 away from the first support member 81 is rotatably connected with the outer machine body 2. Thus, the support assembly 108 may extend and retract by the relative sliding of the first support member 81 and the second support member 82, and support is achieved by the energy storage medium, for example, when the outer machine body 2 rotates downward, the first support member 81 and the second support member 82 relatively move to shorten the support assembly 108, and at this time, the energy storage medium is compressed, and the energy storage medium may provide the above resistance to buffer the downward rotation of the outer machine body 2.

Optionally, one of the first support 81 and the second support 82 is a sleeve, the other is a plunger, the plunger is slidably disposed in the sleeve, and the energy storage medium is a gas, a liquid, or a spring 83 disposed in the sleeve. That is, the first support member 8 may be a pneumatic rod, a hydraulic rod, a spring telescopic rod, or the like. Therefore, through the structural design, the stability and reliability of the relative sliding of the first support member 81 and the second support member 82 can be ensured, and the selective variety of the energy storage medium is more, so that the support blocking effect can be reliably and stably exerted.

Saddle formula window machine among the related art, interior machine is fixed relatively with outer machine, and the upper end of interior machine is connected with the upper end of outer machine, and during the installation, needs to wholly raise saddle formula window machine, and outside the window was released to outer machine, this operation was comparatively laborious, and the outer machine had the risk of outwards falling.

In the window air conditioner 100 according to the embodiment of the present invention, the outer unit body 2 is provided in a pivotable manner, so that the above-mentioned technical problems can be effectively solved. For example, in some embodiments of the present invention, the outer machine body 2 may be rotated 90 ° about a single axis of rotation L from a first state (e.g., the state shown in fig. 1 and 2) to a second state (e.g., the state shown in fig. 3 and 4). For example, the inner machine part 101 may be turned 90 ° by lifting the inner machine part 101, or the inner machine part 101 may be turned to a vertical state (for example, as shown in fig. 5), or the outer machine body 2 may be turned 90 ° by lifting the outer machine body 2, or the outer machine body 2 may be turned to a horizontal position (for example, as shown in fig. 3).

As shown in fig. 3 and 4, when the external unit body 2 is shifted to the second state, the first snap member 61 and the second snap member 62 are engaged to lock the position of the external unit body 2. Wherein, when rotating interior machine part 101 or outer machine body 2, borrow the support resistance of supporting component 108 for outer machine body 2 can easily rotate 90 positions.

As shown in fig. 3 and 4, when the outer machine body 2 rotates 90 ° to the second state, the lower bottom surface of the outer machine body 2 (i.e., the first back plate 21) is flush with the lower bottom surface of the connection bracket 3, so that the outer machine body 2 and the connection bracket 3 can be smoothly and smoothly pushed out.

When the outer machine body 2 reaches the outdoor side, the locking of the first fastening piece 61 and the second fastening piece 62 is released, and then the outer machine body 2 can slowly rotate and fall under the action of the supporting component 108, as shown in fig. 22. Referring to fig. 23, when the outdoor unit body 2 is rotated by 90 ° to return to the first state, it may fall onto the support leg 302 of the mounting bracket 300, and the window air conditioner 100 is supported by the mounting bracket 300, thereby realizing the installation and fixation of the window air conditioner 100, and being safe and reliable.

Therefore, the problems that the saddle type window machine is difficult to install and the outer machine is too heavy to be directly lifted from the window 200 to the outdoor side for installation can be effectively solved. In addition, according to some embodiments of the window air conditioner 100 of the present invention, a low temperature heating function can be achieved, and the window air conditioner can also operate normally at-30 ℃, which is not described herein.
