[0002] With the improvement of people's quality of life, the use of air conditioners is becoming more and more popular. At present, the common room air conditioners mainly include split wall-mounted, split cabinet, window and mobile air conditioners. Among them, the split wall-mounted type is widely loved by consumers because of its beautiful appearance and small space. At present, most people use wall-mounted panels to install the indoor unit of the air conditioner. Usually, the wall-mounted panel is installed on the wall first, and then the indoor unit with the connecting pipe installed is hung on the wall-mounted panel, and then connected with the outdoor unit. However, in Europe and other regions, the connecting pipe is often pre-buried in the wall. At this time, when the wall-mounted panel is used for installation, the indoor unit can only be hung on the wall-mounted panel first, and then it is lifted up to a certain angle to install the connecting pipe. The operating space is small and very inconvenient, and the indoor unit is easy to fall and injure people, which poses considerable safety hazards. Summary of the invention

[0039] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be clearly and completely described below in combination with the specific embodiments of the present disclosure and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0040] In the related art, an up and down folding support structure is added on the basis of an ordinary wall-mounted plate. After the indoor unit is rotated and lifted, the support structure is opened to support the indoor unit, so as to facilitate after-sales personnel to install and maintain it. This design is more complicated to operate. After lifting the indoor unit, one hand is required to support the indoor unit and the other hand is required to open the support structure, which is inconvenient for single-person operation.

[0041] Related technologies also have a support structure that automatically opens when the indoor unit rotates to a certain position. This design simplifies the operation of after-sales personnel. During installation and maintenance, they only need to lift the indoor unit upwards, without having to manually open the support structure. However, due to the structure and installation requirements of the wall-mounted panel, the space in which the indoor unit can be rotated and opened is limited, but it is still inevitable that the indoor unit has a small space for operation. If the lifting angle is too large, the risk of the indoor unit falling is extremely high, which often causes the unit to fall, causing equipment damage or personal injury.

[0042] In the related art, in order to facilitate the installation of the indoor unit, a seat plate is first fixed on the wall, and then the indoor unit is mounted on the seat plate using a wall-mounted plate, and the mounting point is usually designed at the upper end. Therefore, when connecting the pipeline, the indoor unit can only be flipped upward to make the lower edge of the indoor unit away from the wall, forming an opening downward angle. However, with the miniaturization and miniaturization of the indoor unit, the vertical dimensions of the seat plate and the wall-mounted plate are continuously reduced. When the flip-up angle remains unchanged, the distance between the lower edge of the indoor unit and the wall becomes smaller, and the operating space also becomes smaller accordingly.

[0043] Combination Figures 1 to 8 As shown, an embodiment of the present disclosure provides an indoor unit installation system, including: a wall-mounted plate 1, used to connect to the indoor unit 2; a connecting rod assembly 13, one end of the connecting rod assembly 1 is connected to the wall-mounted plate 1, and the other end is connected to the wall, the connecting rod assembly 13 includes a stowed state and an unfolded state, in the stowed state, the connecting rod assembly 13 can fix the indoor unit 2 on the wall; in the unfolded state, the connecting rod assembly 13 can support the indoor unit 2 so that the indoor unit 2 forms a first preset angle and / or a first preset distance with the wall.

[0044] The indoor unit installation system of the disclosed embodiment adopts a connecting rod assembly 13 as a connection between the wall and the wall-mounted plate 1 of the indoor unit 2. With the support of the connecting rod assembly 13, the indoor unit 2 can realize flipping, translation, or flipping and translation movements, and the connecting rod assembly 13 can realize a reasonable design of the motion trajectory and motion range with the help of its own structure. Compared with the wall-mounted plate 1 support structure in the related technology, the indoor unit 2 can have a larger flipping and / or translation space, and the connecting pipe operation area behind the indoor unit 2 is exposed to facilitate after-sales personnel to connect the pipelines. The size of the operating space that can be exposed by the movement of the indoor unit is no longer limited by the size of the indoor unit, the wall-mounted plate and the seat plate. It is easy to use, and the machine body will not fall due to excessive flipping angle, and it is safer.

[0045] The connecting rod assembly 13 of this embodiment can support the indoor unit 2 to achieve flipping, translation, or flipping and translation. The indoor unit 2 flips relative to the wall and can form a first preset angle with the wall. The size of the first preset angle is based on the convenience of after-sales personnel to connect the pipes. The indoor unit 2 translates relative to the wall and can form a first preset distance with the wall. The size of the first preset distance is based on the convenience of after-sales personnel to connect the pipes. The indoor unit 2 flips and translates relative to the wall and can form a first preset angle and a first preset distance with the wall, which makes it easier for after-sales personnel to access the pipes behind the indoor unit 2. Different installation methods are used in different installation environments, which has a wider range of adaptability and stronger practicality.

[0046] In some embodiments, in the unfolded state, the connecting rod assembly 13 can support the indoor unit 2 to move downward in the vertical direction to open, forming a first preset angle with the wall, and at the same time move away from the wall to form a first preset distance with the wall.

[0047] The indoor unit installation system of this embodiment is different from the related art in which the indoor unit adopts an upward-flipping technical solution. It fully considers safety factors and adopts a downward-flipping design. After-sales personnel connect the pipes from the top or the side, and after-sales personnel do not have to stand directly under the indoor unit, which is safer.

[0048] Furthermore, the connecting rod assembly 13 can support the indoor unit 2 to move and open along the wall toward both axial directions of the indoor unit 2, forming a first preset angle with the wall, while moving away from the wall to form a first preset distance with the wall, which can also serve the purpose of increasing the operating space and preventing falling.

[0049] In some embodiments, in order to ensure the stability of the indoor unit 2, the number of the connecting rod assemblies 13 is at least two, and at least two of the connecting rod assemblies 13 are spaced apart along the length direction of the indoor unit 2, so that at least two connecting rod assemblies 13 provide stable balancing support to firmly support the indoor unit 2.

[0050] In some embodiments, the connecting rod assembly 13 includes a first rod 3, a second rod 4, a third rod 5, and a fourth rod 6; the end of the first rod 3 is hinged to the end of the second rod 4, the other end of the first rod 3 is hinged to the wall, the other end of the second rod 4 is hinged to the wall-mounted plate 1, the end of the third rod 5 is hinged to the end of the fourth rod 6, the other end of the third rod 5 is hinged to the wall, the other end of the fourth rod 6 is hinged to the wall-mounted plate 1, and the second rod 4 is cross-hinged with the third rod 5.

[0051] The connecting rod assembly of the present embodiment can support the indoor unit 2 to realize flipping and translational movement, so that the indoor unit 2 has a larger flipping and translational space and a larger operating space. Different installation methods can be used in different installation environments, such as the angle between two walls, the angle between the ceiling and the wall, etc., which has a wider adaptability and stronger practicality.

[0052] In some embodiments, the second rod member 4 is a bent rod member, the second rod member 4 includes a first rod segment 7, a second rod segment 8, and a first bending portion 11, the first rod segment 7 and the second rod segment 8 are bent and connected at the first bending portion 11, and the second rod segment 8 is hinged to the wall-mounted panel 1; and / or, the third rod member 5 is a bent rod member, the third rod member 5 includes a third rod segment 9, a fourth rod segment 10, and a second bending portion 12, the third rod segment 9 and the fourth rod segment 10 are bent and connected at the second bending portion 12, and the fourth rod segment 10 is hinged to the wall.

[0053] Since the connection between the connecting rod assembly 13 and the wall panel 1 and the wall is a single-point hinge, the force on the hinge position is relatively concentrated. For example, the first rod 3 and the third rod 5 are hinged to the wall, resulting in two connection points with relatively concentrated force. In order to prevent the two force points from being too close to each other and causing a large concentrated load on the wall, it is necessary to keep a certain safety distance between the two force points. The second rod 4 and the fourth rod 6 also have the same problem. Therefore, in this embodiment, the third rod 5 is designed as a bent rod, so that the hinge point of the third rod 5 on the wall and the hinge point of the first rod 3 on the wall can be at a certain distance in the direction perpendicular to the wall, thereby avoiding the force concentration on the wall. Similarly, the second rod 4 is designed as a bent rod, which can also avoid the problem of concentrated force on the wall panel 1.

[0054] Preferably, when the first rod segment 7 and the second rod segment 8 are bent and connected at the first bending portion 11, and the third rod segment 9 and the fourth rod segment 10 are bent and connected at the second bending portion 12, the first bending portion 11 and the second bending portion 12 are hingedly connected so that the second rod member 4 and the third rod member 5 are cross-hinged.

[0055] Therefore, compared with the non-bending joint hinge, this embodiment can maximize the distance between the hinge point of the third rod 5 on the wall and the hinge point of the first rod 3 on the wall in the direction perpendicular to the wall, and has the best effect of avoiding force concentration on the wall. Similarly, it also has the best effect of avoiding force concentration on the wall-mounted plate 1.

[0056] Furthermore, the length of the first rod segment 7 is smaller than that of the second rod segment 8, the first bending portion 11 is close to an end of the second rod member 4 away from the wall and the wall-mounted plate 1, and / or the length of the third rod segment 9 is smaller than that of the fourth rod segment 10, and the second bending portion 12 is close to an end of the third rod member 5 away from the wall and the wall-mounted plate 1.

[0057] Therefore, the second rod 4 and the third rod 5 of this embodiment have sufficient length to satisfy the support of the connecting rod assembly 13 for the movement of the indoor unit, so that the indoor unit 2 has a larger flipping and translation space.

[0058] In some embodiments, the second rod 4 is a straight rod, the third rod 5 is a straight rod, and the second rod 4 and the third rod 5 are hinged to form an X shape. Therefore, when the connecting rod assembly 13 is in the retracted state, the second rod 4 and the third rod 5 can completely overlap along the axial direction of the indoor unit 2, and at the same time, the first rod 3 hinged to the second rod 4 and the fourth rod 6 hinged to the third rod 5 will also overlap with the indoor unit 2 in the axial direction, thereby reducing the vertical distance between the wall-mounted plate 1 and the wall, which is suitable for ensuring that the indoor unit 2 has a good close contact effect with the wall when the distance between the wall-mounted plate 1 and the wall is required to be high.

[0059] In some embodiments, the first rod 3, the second rod 4, the third rod 5, and the fourth rod 6 are hingedly connected in parallel in sequence, so that the hinge points of the first rod 3, the third rod 5 and the wall can be staggered in the axial direction of the indoor unit 2, and the hinge points of the second rod 4, the fourth rod 6 and the wall-mounted plate 1 can be staggered in the axial direction of the indoor unit 2, further avoiding the force concentration on the wall and the wall-mounted plate 1. Preferably, the second rod 4 and the third rod 5 are hinged with cylindrical pins, which can meet the working condition of the two rods being hinged in parallel.

[0060] In some embodiments, the connecting rod assembly 13 is provided with a locking device 27, and the locking device 27 can limit the movement of the connecting rod assembly 13 so that the indoor unit is fixed at a position forming a first preset angle and / or a first preset distance with the wall.

[0061] The locking device 27 of this embodiment is used to limit the movement of the connecting rod assembly 13, for example, to limit the maximum movement range of the connecting rod assembly, or to lock the connecting rod assembly 13 in the optimal operating position when the indoor unit 2 does not need to move to the maximum position. The locking device 27 can be a fixed structure that can hinder the rotation of the connecting rod relative to the hinge point, such as a bump, or a moving structure that can be controlled to lock the connecting rod, such as a moving pin or a ratchet mechanism.

[0062] In some embodiments, the connecting rod assembly 13 further includes a first support 14 and a second support 15, wherein the first support 14 is disposed on the wall surface, and the second support 15 is disposed on the wall-mounted plate 1. Preferably, the locking device 27 includes a convex block protruding from the first support 14, and the convex block can be disposed at the lower dead point of the rotational movement of the first rod 3 and the third rod 5, respectively.

[0063] In order to achieve a stable and reliable connection between the connecting rod assembly 13 and the wall surface and the wall-mounted plate 1, the connecting rod assembly 13 can be preassembled as a whole, and the connecting rod assembly 13 has a first support 14 and a second support 15. At the same time, the locking device 27 can be integrally designed on the first support 14, so as to limit the maximum movement range of the connecting rod assembly 13 when the connecting rod assembly 13 supports the indoor unit 2 to flip and translate downward.

[0064] In some embodiments, the first support 14 includes a first hinge portion 16 and a third hinge portion 18, the first rod 3 is hinged to the first support 14 through the first hinge portion 16, and the third rod 5 is hinged to the first support 14 through the third hinge portion 18; and / or, the second support 15 includes a second hinge portion 17 and a fourth hinge portion, the second rod 4 is hinged to the second support 15 through the second hinge portion 17, and the fourth rod 6 is hinged to the second support 15 through the fourth hinge portion.

[0065] The connecting rod assembly 13 of this embodiment has four rods matched in pairs and stably assembled through two supports. The supports serve as force-bearing structures and can be made of materials with higher strength, so that the movement of the indoor unit can be achieved with the help of reliable support from the supports.

[0066] In some embodiments, when the first hinge part 16 and the third hinge part 18 are included; the first hinge part 16 includes a flat pin part 20, a circular hole part 21, and a flat hole part 22, the circular hole part 21 is connected to the flat hole part 22, the flat pin part 20 can slide and switch between the circular hole part 21 and the flat hole part 22, when the flat pin part 20 is in the circular hole part 21, corresponding to the unfolded state of the connecting rod assembly 13, the flat pin part 20 and the circular hole part 21 are rotatably matched, the first rod part 3 can rotate around the first hinge part 16, when the flat pin part 20 is in the flat hole part 22, corresponding to the retracted state of the connecting rod assembly 13, the flat pin part 20 and the flat hole part 22 are stop-rotating matched, and the first rod part 3 is fixed at an angle relative to the first hinge part 16.

[0067] The connecting rod assembly 13 of the present embodiment can be put in the folded state by locking and fixing the first rod 3 through the anti-rotation cooperation between the flat pin member 20 and the flat hole portion 22, thereby locking the entire connecting rod assembly 13, thereby ensuring that in the folded state, the connecting rod assembly 13 can reliably and stably hang the indoor unit 2 on the wall.

[0068] In some embodiments, the third hinged portion 18 includes a flat pin member 20, a circular hole portion 21, and a flat hole portion 22. The circular hole portion 21 is connected to the flat hole portion 22, and the flat pin member 20 can slide and switch between the circular hole portion 21 and the flat hole portion 22. When the flat pin member 20 is in the circular hole portion 21, the flat pin member 20 and the circular hole portion 21 are rotationally matched, and the third rod member 5 can rotate around the third hinged portion 18. When the flat pin member 20 is in the flat hole portion 22, the flat pin member 20 and the flat hole portion 22 are stop-rotating matched, and the third rod member 5 is fixed at an angle relative to the third hinged portion 18.

[0069] The connecting rod assembly 13 of the present embodiment can be put in the folded state by means of the anti-rotation cooperation between the flat pin member 20 and the flat hole portion 22, and by locking and fixing the third rod member 5, thereby locking the entire connecting rod assembly 13, thereby ensuring that in the folded state, the connecting rod assembly 13 can reliably and stably hang the indoor unit 2 on the wall.

[0070] Preferably, when the first hinged part 16 includes a flat pin part 20, a circular hole part 21, and a flat hole part 22, the flat hole part 22 is located below the circular hole part 21 in the vertical direction; when the third hinged part 18 includes a flat pin part 20, a circular hole part 21, and a flat hole part 22, the flat hole part 22 is located below the circular hole part 21 in the vertical direction.

[0071] Therefore, when the connecting rod assembly of this embodiment can be folded, the flat pin member 20 can slide into and stay in the flat hole portion 22 under the action of gravity, and under the action of gravity, the flat pin member 20 is always pressed in the flat hole portion 22 and is not easy to fall out, and the indoor unit 2 is reliably fixed to the wall.

[0072] When the connecting pipe is to be installed or removed, the indoor unit 2 is first lifted upward, so that the flat pin 20 moves upward, disengages from the flat hole 22, and enters the round hole 21. At this time, the flat pin 20 can rotate freely and the indoor unit can be rotated downward to open.

[0073] In some embodiments, the first support 14 is a ∏-shaped structure, and the first support 14 is fixed to the wall surface through a bottom wall 23 opposite to the opening, such as screws. When the first support 14 includes a first hinge 16 and a third hinge 18, the first hinge 16 and the third hinge 18 are respectively arranged on two side walls 24 adjacent to the opening of the first support 14. And / or, the second support 15 is formed on the wall-mounted board 1 by a sheet metal process, such as using a punching and shearing device to punch and shear the board of the wall-mounted board 1, and then folding the sheared board to make it perpendicular to the wall-mounted board 1. When the second support 15 includes a second hinge 17 and a fourth hinge, the second support 15 includes a first seat body 25 and a second seat body 26, the second hinge 17 is arranged on the first seat body 25, and the fourth hinge is arranged on the second seat body 26.

[0074] Thus, the first support 14 of this embodiment can provide stable hinged support for the first rod 3 and the third rod 5, respectively, and the two side walls 24 are respectively used as force-bearing parts, avoiding the problem of force concentration, and at the same time the bottom wall 23 can be firmly connected to the wall surface, with high reliability. The second support 15 can be directly formed on the wall-mounted plate 1 through sheet metal processing, which is convenient and fast to produce, reduces the number of parts, and is easy to install.

[0075] Preferably, the side wall 24 where the first hinge part 16 is located is smaller in dimension perpendicular to the wall than the side wall 24 where the third hinge part 18 is located, and correspondingly, the first seat body 25 is smaller in dimension perpendicular to the wall-mounted plate 1 than the second seat body 26. When the connecting rod assembly is in a retracted state, the shorter side wall 24 corresponds to the longer first seat body 25, and the longer side wall 24 corresponds to the shorter second seat body 26. Thus, the first support 14 and the second support 15 are staggered, which can reduce the dimension of the connecting rod assembly 13 perpendicular to the wall and improve the wall-adhering effect of the indoor unit 2.

[0076] In some embodiments, when the first support 14 includes a first hinge portion 16 and a third hinge portion 18, the projections of the first hinge portion 16 and the third hinge portion 18 along the horizontal direction and / or the vertical direction do not overlap. When the second support 15 includes a second hinge portion 17 and a fourth hinge portion, the projections of the second hinge portion 17 and the fourth hinge portion along the horizontal direction and / or the vertical direction do not overlap.

[0077] Therefore, in the indoor unit installation system of this embodiment, the first hinge part 16 and the third hinge part 18 on the wall side can be projected in the horizontal and vertical directions without overlapping, and the positions are staggered in multiple directions. The second hinge part 17 and the fourth hinge part on the wall-mounted plate 1 side can be projected in the horizontal and vertical directions without overlapping, and the positions are staggered in multiple directions. That is, the four hinge points of the connecting rod assembly 13 are staggered, avoiding the formation of single-point, single-line, and single-surface force, which can effectively improve the stability of the connecting rod assembly 13 and the service life of the connecting rod assembly 13 itself.

[0078] In some embodiments, when the first support 14 includes a first hinge portion 16 and a third hinge portion 18, and the second support 15 includes a second hinge portion 17 and a fourth hinge portion, the first rod segment 7 and the second rod segment 8 are bent and connected at the first bending portion 11, and the third rod segment 9 and the fourth rod segment 10 are bent and connected at the second bending portion 12, the third rod segment 9 is arranged parallel to the first rod member 3, the first rod segment 7 and the fourth rod member 6 are arranged parallel to each other, the second rod segment 8 is bent toward the side where the first rod member 3 is located, and the fourth rod segment 10 is bent toward the side where the fourth rod member 6 is located, the line connecting the first hinge portion 16 and the third hinge portion 18 is parallel to the second rod segment 8, and the line connecting the second hinge portion 17 and the fourth hinge portion is parallel to the fourth rod segment 10.

[0079] Thus, the four rods of this embodiment are connected by pins to form two congruent quadrilaterals: quadrilateral 1 formed by the first rod 3, the first rod segment 7, the fourth rod segment 10, and the first support 14, and quadrilateral 2 formed by the fourth rod 6, the third rod segment 9, the second rod segment 8, and the second support 15. These two quadrilaterals always remain congruent at any time of movement. This feature can be used to maintain the stability of the indoor unit during the downward opening process, and can also effectively avoid scratches and collisions between the indoor unit casing and the wall.

[0080] The indoor unit installation system of this embodiment is installed by first connecting the connecting rod assembly 13 to the wall-mounted plate 1, then installing the connecting rod assembly 13 on the wall, keeping the connecting rod assembly 13 in the retracted state, the flat pin 20 is located in the flat hole 22, and then installing the indoor unit 2 on the wall-mounted plate 1 and fixing it. When the connecting rod assembly 13 is in the retracted state, the flat pin 20 naturally falls into the flat hole 22 under the action of gravity. At this time, the movement of the flat pin 20 is limited, the connecting rod assembly 13 cannot rotate, and the indoor unit 2 is reliably fixed on the wall. When the connecting pipe is to be installed or removed, the indoor unit 2 is first lifted upward so that the flat pin 20 moves upward to the circular hole 21. At this time, the flat pin 20 can rotate freely and the indoor unit 2 can be rotated downward to open; when the indoor unit is opened downward to a certain angle, the first rod 3 and the third rod 5 contact the protrusion as the locking device 27, and are restricted from continuing to move downward. At the same time, the indoor unit 2 is also fixed at this angle, and the connecting pipe can be installed or removed.
