Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an indoor unit of an air conditioner. Background Art

[0002] With the popularity of air conditioners, air conditioners have entered thousands of households. Currently on the air conditioner market, the air guide plate of the air conditioner is connected to the lower shell through an axis hole. When the air conditioner is disassembled, the air guide plate needs to be disassembled first. However, this assembly method makes it very troublesome to disassemble the air guide plate and it is easy to damage the air guide plate.

[0003] In addition, the air guide plate is connected to the shell through an axial hole. At the air outlet of the air conditioner, the air guide plate is affected by the cold and warm air flows. Due to thermal expansion and contraction, it is necessary to leave a gap of about 2 mm on both sides of the air guide plate. This makes it easy for the air guide plate to move laterally, resulting in large and uneven gaps on both sides, affecting the overall appearance of the air conditioner.

[0004] It can be seen from this that it is very necessary to simplify the disassembly process of the air guide plate and fix the air guide plate on the housing of the air conditioner to prevent the air guide plate from moving during operation. Summary of the invention

[0005] The problem solved by the present invention is that the air guide plate in the prior art is difficult to disassemble and is easy to move laterally.

[0006] In order to solve the above problems, the present invention provides an indoor unit of an air conditioner to solve the difficulty of removing the air guide plate on the indoor unit housing of the air conditioner. To achieve the above purpose, the technical solution of the present invention is implemented as follows:

[0007] An indoor unit of an air conditioner comprises a shell with an air outlet and an air guide plate arranged at the air outlet, and also comprises: a bracket fixedly arranged on the shell, the shell is detachably connected to the bracket via a bracket support on the shell, the bracket support comprises a plurality of fixing blocks, a clamping space is formed between the plurality of fixing blocks and the shell, the bracket is clamped into the clamping space for fixing, and the bracket is used to fix the air guide plate.

[0008] The bracket fixed to the air guide plate is arranged to be detachably connected. When the air guide plate is removed, the bracket is also removed together, so as to facilitate cleaning of the outlet air duct. The bracket support formed by a simply arranged fixing block can clip and fix the bracket on the inner machine casing, so as to facilitate installation and removal of the bracket.

[0009] Furthermore, the shell is also provided with a buckle, the buckle is arranged between a plurality of fixing blocks, the bracket is provided with a positioning opening, and the buckle cooperates with the positioning opening.

[0010] By arranging the cooperation between the buckle and the positioning opening, the bracket can be prevented from moving up and down on the inner casing of the air conditioner. At the same time, the limiting cooperation between the buckle and the fixing block can tightly fix the bracket on the bracket support.

[0011] Furthermore, a guiding inclined surface is provided on the buckle.

[0012] The guide slope has a guiding function, which facilitates the quick installation of the bracket.

[0013] Furthermore, a support member is provided on the shell, a groove is provided at the bottom of the bracket, and the support member is clamped in the groove.

[0014] By providing the snap-fit ​​cooperation between the groove and the support member, the fixing effect between the air guide plate and the shell is improved, and the left and right lateral movement of the air guide plate is also restricted.

[0015] Furthermore, a buckle is provided at one end of the bracket, and the buckle protrudes to a side away from the groove.

[0016] After the bracket is installed on the inner casing of the air conditioner, the buckle protrudes from the plane of the casing, which can provide a force-bearing position for the operator's fingers, making it easy to remove the bracket during disassembly.

[0017] Furthermore, a limiting rib is provided on one side of the bracket that cooperates with the clamping space.

[0018] The limiting ribs can not only increase the strength of the bracket, but also reduce the contact area between the bracket and the clamping space after the bracket is inserted into the clamping space of the bracket support, thereby reducing friction and abnormal noise when the air conditioner is running.

[0019] Furthermore, a deformation zone is provided between the buckle handle and the groove.

[0020] The deformation zone is thinner than other surrounding parts, and is prone to deformation when the bracket is disassembled. When the operator's fingers apply external force to the buckle, the deformation zone helps the buckle to fall off from the positioning port of the bracket.

[0021] Furthermore, the bracket is fixed on the shell and located in the middle of the air guide plate, or is fixed on the shell and located in the middle of the air outlet of the indoor unit.

[0022] Setting the bracket in the middle of the air guide plate can improve the stability of the rotation of the air guide plate; setting the bracket in the middle of the air outlet makes the deformation of the air guide plates at both ends of the bracket more uniform due to the thermal expansion and contraction of the air outlet, which can also improve the stability of the rotation of the air guide plate.

[0023] Furthermore, a buckle that can be opened or closed is provided at one end of the bracket, a rotating shaft hole is formed between the buckle and the bracket, and a middle rotating shaft of the air guide plate is arranged in the rotating shaft hole.

[0024] By providing a ring buckle that is easy to open and snap, the air guide plate and the bracket can be quickly installed and disassembled. At this time, the air guide plate and the bracket are detachably connected, and the bracket and the inner machine shell are detachably connected, which is convenient for removing the air guide plate when the air conditioner is disassembled.

[0025] Furthermore, a shaft groove is provided at one end of the bracket, the middle shaft of the air guide plate is inserted into the shaft groove, and the arc formed by the cross section of the shaft groove is a major arc.

[0026] The shaft groove is provided so that the air guide plate can be conveniently snapped into and fixed on the bracket of the shell, thereby realizing quick installation and removal between the air guide plate and the bracket.

[0027] Compared with the prior art, the indoor unit of the air conditioner described in the present invention has the following advantages:

[0028] 1) When the air guide plate of the indoor unit of the air conditioner described in the present invention is disassembled, the bracket fixed to the air guide plate can be conveniently removed from the indoor unit;

[0029] 2) The air guide plate and the bracket are easy to remove, which facilitates further disassembly of the air guide plate;

[0030] 3) The air guide plate will not move laterally, and the gaps between the two sides of the air guide plate and the middle frame of the inner casing are small and uniform. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] Example 1

[0044] In the prior art, one end of the air guide plate of the indoor unit of the air conditioner is connected to the motor to provide power for the rotation of the air guide plate, and the other end is provided with a rotating shaft extending along the length direction of the air guide plate. The rotating shaft is inserted into the reserved hole of the indoor unit casing for rotation. Of course, the air guide plate can also be fixedly connected to the motor at both ends to improve the rotation and wind sweeping effect of the air guide plate.

[0045] Since the air guide plates are mostly long and thin strips, a support component needs to be provided in the middle of the air guide plates to prevent the air guide plates from twisting and deforming during rotation. The air guide plates are fixedly mounted on the housing of the air conditioner indoor unit through the rotating shafts and motors at both ends and the support component in the middle. In this embodiment, the support component in the middle of the air guide plates is a bracket.

[0046] like Figure 1-3 As shown, the present invention provides an indoor unit of an air conditioner, comprising a shell 1 with an air outlet and an air guide plate 3 arranged at the air outlet, a bracket 2 is fixedly arranged on the shell 1, and the bracket 2 is fixed to the shell 1 of the air conditioner in a detachable connection manner, such as a threaded connection, a buckle connection and a hinge connection, and the air guide plate 3 of the air conditioner is fixed to the air conditioner through the bracket 2.

[0047] In the present invention, the bracket 2 is arranged on the shell 1 by means of snap-fitting and fixing. Two fixing blocks 11 are arranged on the shell 1. The fixing blocks 11 and the shell 1 form a snap-fitting space 12. When the bracket 2 is fixed on the shell 1, the bracket 2 is inserted into the snap-fitting space 12 for fixing.

[0048] The fixing block 11 is protrudingly arranged on the shell 1. For the sake of aesthetics and ease of use, the fixing block 11 is arranged on the shell 1 in a flat form. When the bracket is removed, the fixing block 11 occupies a smaller volume on the shell 1, which facilitates the subsequent disassembly of other parts of the air conditioner indoor unit.

[0049] In this embodiment, the direction between the air outlet and the air inlet of the indoor unit of the air conditioner is taken as the up-down direction, and the length direction of the air guide plate is taken as the left-right direction.

[0050] After the bracket 2 is inserted into the clamping space 12 formed by the fixing block 11, the fixing blocks 11 are provided on both sides of the bracket 2 for limiting the position, thereby preventing the air guide plate 3 from moving along the length direction of the air guide plate.

[0051] Preferably, a limiting rib 29 is provided on one side of the bracket 2 that cooperates with the snap-in space 12 to increase the strength of the bracket 2. After the bracket 2 is snapped into the snap-in space 12 of the bracket support, the limiting rib 29 can also reduce the contact area between the bracket 2 and the snap-in space 12, thereby reducing friction noise during the operation of the air conditioner.

[0052] Furthermore, in order to prevent the bracket 2 from moving up and down on the shell 1, a buckle 13 is provided on the shell 1, and the buckle 13 is provided between the fixing blocks 11. Correspondingly, a positioning port 21 is provided on the bracket 2. After the bracket 2 is inserted into the snap-fitting space 12, the positioning port 21 is snap-fitted with the buckle 13, which can prevent the bracket 2 from moving up and down, and make the bracket 2 more firmly fixed.

[0053] Preferably, a guiding bevel is provided on the buckle 13 , and when the bracket 2 is engaged with the bracket support, the guiding bevel guides the edge of the positioning opening 21 to slide along the buckle 13 , so that the bracket 2 can be more easily engaged and fixed with the buckle 13 .

[0054] Furthermore, a support member 14 is provided on the shell 1, and the support member 14 is provided between the fixed blocks 11. Preferably, the support member 14 is provided at the center position of the line connecting the two fixed blocks 11. A groove 22 is provided at the bottom of the bracket 2. When the bracket 2 is assembled on the shell 1, the support member 14 is clamped in the groove 22, which can prevent the bracket 2 from moving left and right.

[0055] The housing 1 of the indoor unit of the air conditioner is provided with a fixing block 11 and a buckle 13, which ensures that the bracket 2 will not move up and down after being clamped on the housing 1; the support member 14 is clamped with the groove 22 of the bracket 2, which ensures that the bracket 2 will not move left and right on the housing 1. In this way, the bracket 2 is firmly clamped and fixed on the indoor unit of the air conditioner, and when the air conditioner is running, the bracket 2 fixed to the air guide plate 3 will not move or sway.

[0056] Furthermore, a buckle 28 is provided at one end of the bracket 2, and the buckle 28 protrudes to a side away from the groove 22. After the bracket 2 is installed on the inner housing 1 of the air conditioner, the buckle 28 protrudes from the plane of the housing 1. When disassembling the air conditioner, the operator's fingers can have a force-bearing part on the bracket 2, which facilitates the removal of the bracket 2.

[0057] The bracket 2 is overall in a "U" or "V" shape. On the one hand, it can allow the part connected to the air guide plate to face the outside of the air outlet, which is convenient for installation and disassembly. On the other hand, it can reduce the obstruction of the air outlet and reduce the influence of the bracket 2 on the air outlet of the air conditioner. At the same time, the bracket 2 is small in size and beautiful in appearance.

[0058] The bracket 2 is provided with a deformation zone 211, and the deformation zone 211 is located between the buckle 23 and the groove 22. The thickness of the deformation zone 211 is relatively thin, and the deformation zone 211 is easy to deform when the bracket 2 is disassembled. When the operator's fingers apply external force to the buckle 23, the deformation zone 211 is conducive to the buckle 13 falling off from the positioning port 21 of the bracket 2.

[0059] The number of the brackets 2 is more than one to improve the fixing effect of the air guide plate 3. In this embodiment, one bracket 2 is selected and the bracket 2 is set at the middle position of the air guide plate 3 on the shell 1.

[0060] In the prior art, it is common practice for the indoor unit of the air conditioner to set a motor drive component and other parts at one end of the indoor unit casing 1. Therefore, the length of the air outlet of the air conditioner is smaller than the length of the casing 1. For the beauty of the air conditioner, the length of the air guide plate 3 is set to be consistent with the length of the casing 1 of the indoor unit of the air conditioner, and a "fake air outlet" is formed on one side of the indoor unit of the air conditioner. At the "fake air outlet plate", the indoor unit of the air conditioner has an air guide plate 3 but no air outlet.

[0061] The bracket 2 can be arranged on the housing 1 and located in the middle of the air guide plate, or can be arranged on the housing 1 and located in the middle of the air outlet. When the bracket 2 is arranged in the middle of the air guide plate 3, the stability of the rotation of the air guide plate 3 can be improved; when the bracket 2 is arranged in the middle of the air outlet, the deformation of the air guide plates at both ends of the bracket 2 due to the thermal expansion and contraction of the air outlet is more uniform, which can also improve the stability of the rotation of the air guide plates.

[0062] The indoor unit of the air conditioner provided by the present invention facilitates the disassembly and installation of the air guide plate 3 of the indoor unit of the air conditioner. The user can directly disassemble the bracket 2 and the shell 1 and remove the air guide plate 3.

[0063] Example 2

[0064] like Figure 4-8 As shown, based on the first embodiment, this embodiment provides an indoor unit of an air conditioner in which the bracket 2 and the air guide plate 3 can also be easily disassembled and installed.

[0065] One end of the bracket 2 is arranged on the housing 1, and the other end is provided with a buckle 23. Figure 5 As shown, the buckle 23 can be opened or buckled on the bracket 2. When the buckle 23 is buckled, the buckle 23 and the bracket 2 form a shaft hole 24, and the middle shaft 31 of the air guide plate 3 is wrapped in the buckle 23. The air guide plate 3 rotates on the bracket 2 through the middle shaft 31;

[0066] By providing a ring buckle 23 that can be opened and snapped, the air guide plate 3 is assembled on the bracket 2 and then fixed on the inner machine casing 1 of the air conditioner, so as to facilitate the detachable connection between the air guide plate 3 and the casing 1, simplify the assembly and disassembly process of the inner machine of the air conditioner, and during the disassembly process, the air guide plate 3 only needs to be slightly deformed and is not easily damaged.

[0067] One end of the buckle 23 is pivotally connected to the bracket 2, and the other end is snap-fitted to the bracket 2. The buckle 23 can be opened or closed on the bracket 2 by the pivotal connection, so as to facilitate the installation and disassembly between the air guide plate 3 and the bracket 2.

[0068] Preferably, the buckle 23 is arched, and the middle rotating shaft 31 of the air guide plate 3 is wrapped in the buckle 23. Axle holes 231 are provided on both sides of the buckle 23, and a fixed shaft is correspondingly provided on the bracket 2. The axle hole 231 passes through the fixed shaft on the bracket, and the buckle 23 is fixed on the bracket 2 and rotates around the fixed shaft to form a pivot connection. When the buckle 23 is assembled or disassembled with the bracket 2, the axle holes 231 on both sides are respectively fixed or disengaged from the fixed shaft, and the parts on the bracket 2 can be further disassembled and disassembled, and the indoor unit of the air conditioner is more convenient to assemble.

[0069] Furthermore, a card interface 232 is provided on the ring buckle 23, and a card block 26 is provided on the bracket 2. When the ring buckle 23 is buckled, the card block 26 is buckled into the card interface 232, so that the ring buckle 23 is buckled on the bracket 2. The card structure of the card interface 232 and the card block 26 tightly matches the ring buckle 23 with the bracket 2, thereby preventing the intermediate rotating shaft 31 in the ring buckle 23 from falling off and the air guide plate 3 from malfunctioning.

[0070] When the buckle 23 is buckled on the bracket 2, the intermediate shaft 31 is wrapped in the buckle 23. Since the intermediate shaft 31 of the air guide plate 3 is limited and fixed in the buckle 23, during the operation of the indoor unit of the air conditioner, the intermediate shaft 31 is prevented from falling off or loosening from the buckle 23, causing the air guide plate 3 to move or malfunction.

[0071] Preferably, a positioning block 233 is provided on the ring buckle 23, and the positioning block 233 is provided between the shaft holes 231. The positioning block 233 is provided with a positioning hole, and the positioning hole matches with the protrusion on the bracket. The positioning hole of the positioning block 233 matches with the protrusion, which can keep the rotation shaft hole 24 formed after the ring buckle 23 is buckled without deformation.

[0072] Axial holes 231 are provided on both sides of the ring buckle 23, and a gap is provided between the two axis holes 231. When the ring buckle 23 is installed on the bracket 2, the fixing parts where the axis holes 231 on both sides are located are slightly deformed, so that the axis holes 231 of the ring buckle 23 are clamped on the fixed shaft on the bracket 2.

[0073] When the air guide plate 3 is assembled with the shell 1, the buckle 23 is opened, the middle shaft 31 is placed in the shaft hole 24 in the buckle 23, the buckle 23 is fastened, and the middle shaft 31 of the air guide plate 3 rotates in the buckle 23; when the air guide plate 3 needs to be removed, the buckle 23 is opened, and the middle shaft 31 of the air guide plate 3 is taken out from the shaft hole 24, which is simple and convenient; the installation method at both ends of the air guide plate 3 is the same as the prior art and will not be repeated here.

[0074] During the operation of the indoor air guide plate 3 of the air conditioner, one end connected to the motor is tightly fixed, but during the rotation of the other end, in order to ensure the normal rotation of the air guide plate 3, there is a gap between the rotating shaft of the air guide plate 3 and the reserved hole on the shell 1, which may also cause the air guide plate 3 to move in the length direction. In order to solve this problem, the present invention provides a baffle 32 on the intermediate rotating shaft 31 of the air guide plate 3. The baffle 32 is annular and is arranged on the circumferential surface of the intermediate rotating shaft 31. A positioning groove 25 is also provided on the bracket 2. The baffle 32 cooperates with the positioning groove 25 to prevent the air guide plate 3 from moving.

[0075] Preferably, the baffle 32 has a pair of Figure 6 As shown, the baffles 32 are arranged on both sides of the middle rotating shaft 31, and the positioning grooves 25 on the bracket 2 are arranged on both sides of the rotating shaft hole 24. When the air guide plate 3 is fixed on the bracket 2, the baffles 32 are fixed in the two positioning grooves 25. The two baffles 32 also have a clamping and fixing effect, so that the fixation between the air guide plate 3 and the bracket 2 is more stable.

[0076] Example 3

[0077] like Fig. 9 As shown, in this embodiment, when the air guide plate 3 is installed on the bracket 2, the middle shaft 31 of the air guide plate 3 is inserted into the shaft groove 27 of the bracket 2, and the arc formed by the shaft groove 27 is a major arc. At this time, the air guide plate 3 can be fixed on the bracket 2 of the shell 1 without using the buckle 23.

[0078] When the shaft groove 27 is assembled with the intermediate shaft 31, the intermediate shaft 31 is inserted therein through the elastic deformation of the shaft groove 27; when the air guide plate 3 needs to be removed, it only needs to apply external force to the air guide plate 3, the shaft groove 27 will undergo elastic deformation, and the intermediate shaft 31 of the air guide plate 3 can be removed from the bracket 2.

[0079] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
