Description

[0002] Air conditioners are indispensable household appliances in modern life, which have the function of controlling the temperature of the environment. The air outlet direction of the indoor unit is usually controllable. The current air sweeping direction of the indoor unit is generally four-way sweeping, i.e. up, down, left and right, the up and down air directions are controlled by the air deflector which can rotate up and down, and the left and right air directions are controlled by the blade which can rotate left and right. Among them, the blade is at the air outlet of the air conditioner, which not only guides the air flow but also blocks part of the air flow. Especially in the soft wind mode of some air conditioners on the market, after passing through the air baffle with a microporous structure in the air conditioner, the user contacts the airflow with slow flow rate and small flow. At this time, the blade air deflection seriously reduces the air outlet speed and air volume of the air conditioner, shortens the normal air supply distance of the air conditioner, and affects the performance of the air conditioner. Although the left and right air sweeping functions of the air conditioner are not necessary in the actual use of the wall-mounted air conditioner, the left and right blades of the existing air conditioner are fixedly installed in the air conditioner, which affects the air outlet speed and flow.

It should be understood that these embodiments are provided in order to make the present disclosure complete and comprehensive, and to adequately convey the ideas of these exemplary embodiments to those of ordinary skill in the art. In the drawings, the thickness of layers and regions can be exaggerated for clarity, and the same reference numerals are used to denote the same elements, so that a description thereof will be omitted.

[0061] In combination Figures 1 to 32 As shown, according to specific embodiments of the present application, an indoor unit is provided.

[0062] The indoor unit comprises a bottom shell 10, a sweeping assembly 20, a shielding assembly 30, and a driving assembly 40. The bottom shell 10 has an air outlet channel 11 and a containing space 12 communicating with the air outlet channel 11. The bottom wall of the air outlet channel 11 is provided with a vane slot 13. The sweeping assembly 20 is movably arranged relative to the bottom shell 10. The sweeping assembly 20 has a working position in the air outlet channel 11 and a hidden position in the containing space 12. The shielding assembly 30 is movably arranged relative to the bottom shell 10. The shielding assembly 30 has a closed position shielding the vane slot 13 and an avoiding position away from the vane slot 13. The driving assembly 40 is at least one. The driving assembly 40 is connected with the side wall of the air outlet channel 11 and connected with the sweeping assembly 20 and the shielding assembly 30 respectively. The driving assembly 40 can drive the sweeping assembly 20 to switch between the working position and the hidden position through the vane slot 13, and the driving assembly 40 can drive the shielding assembly 30 to switch between the closed position and the avoiding position.

[0063] According to the technical scheme of the present application, the indoor unit can drive the sweeping assembly 20 to switch between the working position and the hidden position through the driving assembly 40, so that the indoor unit can use the sweeping assembly 20 to change the air direction when needed and hide the sweeping assembly 20 when the air direction is not needed to be changed, preventing the sweeping assembly 20 from always being located in the air outlet channel 11 to affect the air outlet speed and air volume of the indoor unit. Meanwhile, the driving assembly 40 is used to drive the shielding assembly 30 to switch between the closed position and the avoiding position, so that the air outlet channel 11 and the containing space 12 are selectively communicated. When the shielding assembly 30 is located in the closed position, the air outlet channel 11 is separated from the containing space 12, which can effectively prevent the air flow from leaking and reduce the condensation phenomenon in the indoor unit. According to the technical scheme of the present application, the problem that the sweeping assembly of the indoor unit in the prior art shields the air outlet channel to affect the air outlet speed and air volume is effectively solved.

[0064] By setting the air sweeping assembly 20 as a free hidden type, and designing the shielding assembly 30 to cooperate to make the indoor unit have two modes of pushing out and stowing the air sweeping assembly. When the user needs to use the left and right air sweeping functions, the air sweeping assembly 20 can be controlled to be pushed out, and the air direction can be adjusted. When the user does not need to use the air sweeping assembly 20, it is stowed inside the air conditioner to reduce the air outlet resistance and increase the air volume. The existing part of the indoor unit sets the air sweeping assembly 20 as a detachable type, and when the user needs to sweep the air sweeping assembly 20, it cannot be quickly installed. The technical scheme of the above embodiment does not need to rely on disassembly operation in two modes, and can be freely selected and controlled by the user. Through the improvement of the bottom shell 10, the air sweeping assembly 20 and other structures, the indoor unit structure is relatively simple and reliable, at least one driving assembly 40 can be used to realize two modes, and the cost of the indoor unit is also well controlled. It should be noted that the driving assembly 40 is electrically connected with the controller, so the user can realize the functions of left and right air sweeping or hiding the air sweeping assembly 20 through manual control or remote control. When the air sweeping assembly 20 is in the working position, the air direction can be adjusted according to the user's needs, and different mode control can be performed.

[0065] Further, the shielding assembly 30 is in the closed position when the air sweeping assembly 20 is in the working position or the hidden position; the shielding assembly 30 is in the avoiding position when the air sweeping assembly 20 is in the containing space 12 and the air outlet channel 11 at the same time. That is to say, as shown in Figure 22 and Figure 30 When the air sweeping assembly 20 has entered any one of the air outlet channel 11 or the containing space 12, the shielding assembly 30 seals the blade slot 13, which can effectively prevent the exchange of air flow in the containing space 12 and the air outlet channel 11, and affect the working effect of the indoor unit. As shown in Figure 26 When the shielding assembly 30 is away from the blade slot 13, the air sweeping assembly 20 can be switched between the working position and the hidden position through the blade slot 13.

[0066] As shown in Figure 4 The air sweeping assembly 20 includes a rotating shaft 21 and a plurality of blades 22 arranged at intervals on the rotating shaft 21, and at least one end of the rotating shaft 21 is connected with the driving assembly 40. The air sweeping assembly 20 realizes the left and right air sweeping functions of the indoor unit.

[0067] As shown in Figure 3 The driving assembly 40 is two. The two driving assemblies 40 are respectively connected with the side walls of the two ends of the length direction of the air outlet channel 11. The two driving assemblies 40 are respectively connected with the two ends of the rotating shaft 21. The shielding assembly 30 includes a baffle, and the two ends of the length direction of the baffle are respectively connected with the two driving assemblies 40. In this way, the two ends of the air sweeping assembly 20 have the same movement accuracy, and the indoor unit is prevented from having gaps and being not beautiful due to insufficient rigidity of the air sweeping assembly 20.

[0068] Specifically,Figure 2 An internal view of the indoor unit with some parts concealed is shown. Figure 3 A schematic diagram of the back of the indoor unit is shown. Figure 5 A schematic diagram of the drive component 40 is shown. Figure 7 A schematic diagram of the rear of the drive assembly 40 after it is hidden from the drive housing 42 is shown. Figure 8 A front view of the drive assembly 40 after the drive housing cover 41 is hidden is shown. Figure 9 A side sectional view of the drive assembly 40 is shown. Figure 10 A schematic diagram of the drive box cover 41 is shown. Figure 11 A schematic diagram of the drive housing 42 is shown. Figure 16 A top view of the rack ring is shown. Figure 19 A side view of the shielding assembly 30 is shown. The shielding assembly 30 includes a baffle, and two baffle mounting holes 55 are provided on both sides of the baffle. The baffle mounting holes 55 are used to connect with the baffle mounting member 4335. Figure 20 A schematic diagram of the bottom shell 10 is shown. Figure 1 The document also shows a filter 50, a panel body 51, a panel 52, and an air guide plate 53.

[0069] like Figure 6 As shown, the drive assembly 40 includes: a drive housing cover 41, a drive housing base 42, a first motion assembly 43, and a second motion assembly 44. The drive housing base 42 is connected to the drive housing cover 41. A receiving cavity is formed between the drive housing base 42 and the drive housing cover 41. The first motion assembly 43 is located within the receiving cavity. The first motion assembly 43 is connected to the drive housing base 42. The first motion assembly 43 and the drive housing base 42 are movably disposed relative to each other. The first motion assembly 43 is connected to the shielding assembly 30. The first motion assembly 43 can drive the shielding assembly 30 to switch between a closed position and a clearance position. The second motion assembly 44 is located within the receiving cavity. The second motion assembly 44 is connected to the drive housing cover 41. The second motion assembly 44 is connected to the sweeping assembly 20. The second motion assembly 44 is connected to the first motion assembly 43. During the movement of the shielding assembly 30, the first motion assembly 43 can drive the second motion assembly 44 to move, thereby switching the sweeping assembly 20 between a working position and a concealed position. The drive box cover 41 and drive box base 42 together form the drive box, housing the first motion component 43 within the receiving cavity. This reduces the space occupied by the drive component 40 and simplifies its assembly steps. The second motion component 44 is connected to the first motion component 43. By using the first motion component 43 to drive the second motion component 44, a single power source can simultaneously drive the shielding component 30 and the sweeping component 20, facilitating rhythmic coordination between the two components.

[0070] like Figure 6The F1 direction shown in the figure is the first direction, and the F2 direction is the second direction. One side wall of the drive box cover 41 is provided with a first outlet 411 in the first direction. One side wall of the drive box cover 41 is provided with a second outlet 412 in the second direction. The first movement assembly 43 comprises a first motor 431, a driving gear 432, and a rack ring 433. The first motor 431 is connected with a motor mounting column 421 provided on the drive box seat 42. The driving gear 432 is connected with the first motor 431. Part of the driving gear 432 is located in the rack ring 433. The rack ring 433 is selectively engaged with the driving gear 432. The rack ring 433 is movably arranged with the drive box seat 42. The rack ring 433 is connected with a baffle, and part of the driving gear 432 passes through the rack ring 433 and is connected with the second movement assembly 44. The first motor 431 can drive the driving gear 432 to rotate, so that part of the rack ring 433 passes through the first outlet 411 and moves in the first direction, and the rotation of the driving gear 432 can drive part of the second movement assembly 44 to pass through the second outlet 412 and move in the second direction. By using the technical scheme of the embodiment, the first motor 431 is rotated to drive the two movement assemblies to move, the energy utilization efficiency is improved, and the control logic is simplified.

[0071] The driving gear 432 comprises a main gear 4321 and a secondary gear 4322 connected with the main gear 4321. The main gear 4321 and the secondary gear 4322 are coaxially arranged. The main gear 4321 is circumferentially provided with a first gear structure 4323. Part of the outer circumferential edge of the secondary gear 4322 is provided with a second gear structure 4324, the circumferential length of the second gear structure 4324 is equal to the circumferential length of the first gear structure 4323, and the diameter ratio of the secondary gear 4322 to the main gear 4321 is A, wherein 2.9≤A≤3.1. Since the main gear 4321 and the secondary gear 4322 are arranged in mesh with different components, the gear length in the embodiment is set in proportion, so that the main gear 4321 and the secondary gear 4322 can mesh with a preset multiple distance in the same time, and the movement beat coordination between the second movement assembly 44 and the first movement assembly 43 is realized.

[0072] As shown in the figure, Figure 14 The rack ring 433 is an annular structure. The rack ring 433 comprises two symmetrical straight connection segments 4331, and the extension direction of the straight connection segment 4331 is parallel to the first direction. The same end of the two straight connection segments 4331 is connected by an arc connection segment 4332. There are two arc connection segments 4332. The straight connection segment 4331 is provided with a third gear structure 4333, and the length of the third gear structure 4333 is the same as the length of the first gear structure 4323. In fact, the rack ring 433 presents a ring track structure.

[0073] AsFigure 15 and Figure 16 As shown, the rack ring 433 is also provided with multiple rack ring guide rods 4334. Multiple rack ring guide grooves 422 are spaced apart along a second direction on the side wall of the drive housing 42. The rack ring guide grooves 422 extend along a first direction. The multiple rack ring guide rods 4334 are arranged in a one-to-one correspondence with the multiple rack ring guide grooves 422. The rack ring guide rods 4334 pass through the rack ring guide grooves 422 and are connected to the drive housing cover 41. A baffle mounting member 4335 is provided on the side of the rack ring 433 opposite to the rack ring guide rods 4334. A baffle mounting groove 413 is provided on the side wall of the drive housing cover 41 along the first direction. The baffle mounting member 4335 passes through the baffle mounting groove 413 and is connected to a baffle. The rack ring 433 is movably positioned relative to the drive housing cover 41. The rack ring guide rod 4334 and the rack ring guide groove 422 work together to ensure good connection stability between the rack ring 433 and the drive box base 42, while also facilitating installation and sliding.

[0074] like Figure 6 As shown, the second motion component 44 includes a second motor 441 and a sweeping motor mount 442. The second motor 441 is connected to the rotating shaft 21. The sweeping motor mount 442 is connected to the second motor 441. A fourth toothed structure 4421 is provided on the sweeping motor mount 442. The sweeping motor mount 442 meshes with the main wheel 4321 through the fourth toothed structure 4421. The length of the fourth toothed structure 4421 is greater than the length of the first toothed structure 4323. The sweeping motor mount 442 and the drive box cover 41 are movably arranged relative to each other. The rotation of the main wheel 4321 can drive the sweeping motor mount 442 to move in a second direction, thereby driving the sweeping component 20 to move. In fact, the sweeping motor mount 442 has a "P"-shaped structure. The second motor 441 can be fixed through the sweeping motor mount 442, and a transmission relationship is established with the rack ring 433.

[0075] The sweeping motor mount 442 includes an annular mounting portion 4422 and a linear transmission portion 4424. The annular mounting portion 4422 has a mounting cavity for mounting a second motor 441. Multiple motor mount guide rods 4423 are provided on the side of the annular mounting portion 4422 away from the second motor 441. Multiple motor mount guide grooves 414 are provided on the side wall of the drive box cover 41 along a second direction. The multiple motor mount guide rods 4423 are arranged in a one-to-one correspondence with the motor mount guide grooves 414. One end of the linear transmission portion 4424 is connected to the annular mounting portion 4422, and the other end of the linear transmission portion 4424 extends along the second direction. A fourth toothed structure 4421 is provided on the top of the linear transmission portion 4424. This arrangement allows the rack ring 433 to transmit power to the sweeping motor mount 442, which is then converted into displacement along a preset direction, thereby driving the baffle.

[0076] like Figure 10As shown, the drive box cover 41 has two motor mount guide grooves 414 and one baffle mounting groove 413. Figure 11 As shown, the drive housing 42 also has two rack ring guide grooves 422 and a motor mounting post 421. (As indicated...) Figure 12 and 13 As shown, the driving gear 432 consists of two parts: a main gear 4321 and a secondary gear 4322. The main gear is a standard gear with a circumference of L. The diameter of the secondary gear is approximately three times that of the main gear. The secondary gear has a second gear tooth structure 4324, with a tooth segment arc length also of L. Figure 14 As shown, the rack ring 433 is a racetrack-shaped annular part, with a third gear tooth structure 4333 on the inner side of its two straight sections, namely rack a (i.e. Figure 14 The third gear structure 4333 in the upper middle part), rack b (i.e. Figure 14 The upper middle part has a third gear structure 4333, with two rack segments of equal length, also L. The rack ring 433 has two rack ring guide rods 4334 on its front and a baffle mounting piece 4335 on its back. The sweeping motor base 442 has a fourth tooth structure 4421 on the outer side of its linear transmission part 4424, defined as rack c, with a length slightly greater than L. The sweeping motor base 442 has two motor base guide rods 4423 on its front. The baffle is a thin-walled part with baffle mounting holes 55 on both sides; the bottom shell 10 has blade grooves 13 for the blades 22 to pass through.

[0077] The assembly sequence of the drive assembly 40 is described below: During assembly, the drive gear 432 is mounted on the first motor 431, then the first motor 431 is installed on the drive housing 42, and then the rack ring guide rod 4334 is aligned with the right edge of the guide rail on the drive housing 42 (according to...). Figure 11 (Right edge of view) Install rack ring 433, then install shaft cover 54 for fixation; install second motor 441 on sweeping motor mount, then align motor mount guide rod 4423 on sweeping motor mount 442 with upper edge of guide rail on drive box cover 41 (press) Figure 10 After the top edge of the view is assembled, install the shaft cover to fix it; finally, install the assembled drive box cover 41 and drive box base 42 to complete the drive assembly. At this time, the right end of the rack b on the rack ring 433 meshes with the lower end of the auxiliary wheel 4322 on the drive gear 432, and the lower end of the rack c on the sweeping motor base 442 meshes with the main wheel 4321 on the drive gear 432.

[0078] During the installation of the whole machine, the drive assembly 40 is installed on the outer side of the bottom shell air duct, the blade 22 is connected to the second motor 441, and the baffle is connected to the rack ring 433 after passing through the baffle mounting groove 413 on the drive box cover 41.

[0079] like Figures 21-32As shown, when the blade 22 needs to be raised for recovery, the first motor 431 drives the driving gear 432 to rotate counterclockwise, the teeth of the main wheel of the driving gear 432 engage with the rack on the air sweeping motor base 442 to drive the air sweeping motor base 442, the second motor 441 and the blade 22 to descend; the teeth of the secondary wheel of the driving gear 432 engage with the rack b on the rack ring 433 to drive the rack ring 433 and the baffle to move to the right side to make room, and the blade slot 13 of the bottom shell is gradually opened; due to the diameter difference between the main wheel and the secondary wheel of the driving gear 432, when the height of the blade 22 is lowered to 1 / 3*L, the secondary wheel of the driving gear 432 has been rotated to engage with the left end of the rack b on the rack ring 433, at this time the baffle is located at the rightmost side, and the blade slot 13 of the bottom shell is completely opened; the driving gear 432 continues to rotate, the secondary wheel disengages from the rack b on the rack ring 433, the rack ring 433 and the baffle no longer move at the maximum opening position, and the main wheel of the driving gear 432 continues to drive the air sweeping motor base 442, the second motor 441 and the blade 22 to descend; when the height of the blade 22 is lowered to 2 / 3*L, the secondary wheel of the driving gear 432 starts to engage with the left end of the rack a on the rack ring 433, the driving gear 432 continues to rotate to drive the blade 22 to continue to descend, at the same time, the rack ring 433 and the baffle move to the left, and the blade slot 13 of the bottom shell is gradually closed; when the height of the blade 22 reaches L (at this time the blade 22 has been completely located below the bottom shell air duct), the secondary wheel of the driving gear 432 engages with the right end of the rack a on the rack ring 433, the main wheel engages with the upper end of the rack on the air sweeping motor base 442, the blade 22 descends to the lowest point, the baffle returns to the original position to block the blade slot 13 of the bottom shell, and the blade hiding action is completed.

[0080] As shown in FIG. 4, the driving assembly 40 is located in the working position, that is, the blade 22 is raised. Figure 21 and Figure 22 As shown in FIG. 4, the driving assembly 40 is located in the working position, that is, the blade 22 is raised. Figure 23 and Figure 24 As shown in FIG. 4, the driving assembly 40 is located in the working position, that is, the blade 22 is raised. Figure 23 As shown in FIG. 4, the driving assembly 40 is located in the working position, that is, the blade 22 is raised. Figure 23 As shown in FIG. 4, the driving assembly 40 is located in the working position, that is, the blade 22 is raised. Figure 23The right end of the rack ring 433 is the second end. At this time, the teeth of the main wheel 4321 mesh with the end of the fourth tooth structure 4421 away from the annular mounting part 4422, and the second end of the third tooth structure 4333 meshes with the second tooth structure 4324 on the auxiliary wheel 4322. When the main wheel 4321 rotates, the meshing point of the third tooth structure 4333 and the second tooth structure 4324 moves towards the first end, and the rack ring 433 moves along the axial direction, causing the baffle to gradually avoid it. The process of gradually avoiding it is as follows: Figures 25 to 28 As shown.

[0081] like Figure 25 and Figure 26 This diagram illustrates the state of the indoor unit when the air-sweeping assembly 20 is in the working position and the concealed position, i.e., when the blades 22 are switching positions. Figure 27 and Figure 28 This diagram illustrates the positional state of the drive assembly 40 when the indoor unit is in the working position and the concealed position, i.e., when the blades 22 are switching positions.

[0082] like Figure 29 and Figure 30 The diagram shows the indoor unit in the concealed position when the air-sweeping assembly 20 is fully within the accommodating space, and the baffle completely seals the blade slot 13. Figure 31 and Figure 32 This diagram shows the position of the drive assembly 40 when the indoor unit is in the hidden position with the air swing assembly 20 in the hidden position.
