DETAILED DESCRIPTION OF THE INVENTION

[0062] Some examples of the invention are described in detail below in combination with the drawings. It should be understood that the examples described here are merely used to describe and explain the invention and are not intended to limit the invention.

[0063] In the invention, unless otherwise stated, orientation words used such as "front", "rear", "left" and "right" are defined based on an XY coordinate system in Figs. 1 and 2. Specifically, direction X refers to a front-rear direction, in which a side indicated by an arrow is front, and the other side is rear. Direction Y refers to a left-right direction, in which a side indicated by an arrow is left, and the other side is right. The up-down direction can refer to a gravity direction of a corresponding component. "Inner" and "outer" refer to an inner contour and an outer contour of each part. "Upstream" and "downstream" are defined based on a flow direction of air. Terms used such as "first" and "second" are to distinguish one element from another, and do not indicate sequence and importance. Furthermore, when the following description relates to the drawings, the same reference numerals in different drawings indicate the same or similar elements, which are not repeated here.

[0064] According to some examples of the invention, an indoor unit is provided. With reference to Figs. 1-3, the indoor unit includes a cross-flow fan 1, an air duct assembly 2, an air outlet assembly 3 and a protective net assembly 4. The cross-flow fan 1 is arranged in the air duct assembly 2, the air outlet assembly 3 is in communication with a downstream portion of the air duct assembly 2, and the protective net assembly 4 is arranged between the air duct assembly 2 and the air outlet assembly 3.

[0065] Through the above technical solution, in the indoor unit provided in the invention, by arranging the protective net assembly 4 between the air duct assembly 2 and the air outlet assembly 3, an inner space of the indoor unit can be used to accommodate the protective net assembly 4, that is to say, a space between the air duct assembly 2 and the air outlet assembly 3 can be used to accommodate the protective net assembly 4. In this way, compared with an example in which the protective net assembly 4 is arranged outside the air outlet assembly 3, the protective net assembly 4 of the invention can be arranged inside the indoor unit, thus facilitating compact design of the indoor unit.

[0066] In some examples of the invention, with reference to Figs. 1-3, the air duct assembly 2 may have a guide passage 21. The guide passage 21 obliquely extends rightwards gradually from rear to front and has an outlet 22. In this way, air flowing out of the cross-flow fan 1 may flow into the guide passage 21 and then flow rightwards from rear to front to the outlet 22 gradually. The air outlet assembly 3 may have a first air outlet 31 and a second air outlet 32. The first air outlet 31 is arranged on a left side of the second air outlet 32. The protective net assembly 4 includes a protective net 41 and a flow diversion member 42. The protective net 41 includes a protective net body 411 arranged at the outlet 22. The flow diversion member 42 is arranged on a front side of the protective net body 411 and is located on a downstream portion of the protective net body 411. The flow diversion member 42 is configured to guide air flowing through the flow diversion member to the first air outlet 31. Here, the flow diversion member 42 of the invention may implement pre-diversion on air flowing out of the cross-flow fan 1. Specifically, the air flowing out of the cross-flow fan 1 may flow rightwards from rear to front to the outlet 22 gradually. In this case, a part of the air may pass through the protective net body 411 to flow rightwards and forwards and flow out from the second air outlet 32, and another part of the air may pass through the protective net body 411, flow leftwards and forwards through guide of the flow diversion member 42, and flow out from the first air outlet 31. In this case, the pre-diversion on the air by the flow diversion member 42 is beneficial to uniform air outflow of the first air outlet 31 and the second air outlet 32, that is, substantially the same air volume from the first air outlet 31 and the second air outlet 32. Thus, the indoor unit of the invention may be configured as a double-outlet-type indoor unit.

[0067] In some examples of the invention, with reference to Figs. 1-3, 6 and 7, the protective net body 411 may cover the outlet 22 and have a left end, a right end, and a middle end located between the left end and the right end. The middle end may be understood as being at a position bisecting the protective net body 411 in a left-right direction. The left end is arranged on a leftmost side of the outlet 22. The right end is arranged on a rightmost side of the outlet 22. The flow diversion member 42 is configured as a flow diversion rib. The flow diversion rib has a first upstream end 421 and a first downstream end 422. The first upstream end 421 is arranged on a right side of the middle end. Here, since the air flowing out of the cross-flow fan 1 flows rightwards from rear to front gradually to the outlet 22, the air flowing at a right side of the outlet 22 has a higher flow velocity, and the air flowing at a left side of the outlet 22 has a lower flow velocity. Thus, by arranging the first upstream end 421 at a right side of the middle end, more air flowing at a lower flow velocity may flow to the first air outlet 31 through the guide of the flow diversion member 42, and less air flowing at a higher flow velocity may flow rightwards and forwards to the first air outlet 31. In this case, such an arrangement can achieve uniform air outflow of the first air outlet 31 and the second air outlet 32.

[0068] In some examples of the invention, with reference to Figs. 1-3, 6 and 7, the first downstream end 422 may be located on a left side of the first upstream end 421. In this way, the flow diversion member 42 may conveniently guide the air to flow leftwards.

[0069] In some examples of the invention, with reference to Figs. 1-3, 6 and 7, the flow diversion rib may be configured to be of an arc-shaped plate structure. Certainly, in other examples, the flow diversion rib may also be configured to be of a flat-plate structure, which is not limited here.

[0070] In some examples of the invention, with reference to Figs. 1-3, 6 and 7, the protective net 41 includes a protective net body 411. The protective net body 411 is configured to be of a grid shape and has a vertical rib 4111 and a horizontal rib 4112 connected together. The vertical rib 4111 is arranged to obliquely extend rightwards gradually from rear to front. In this way, the vertical rib 4111 may adapt to the air flowing rightwards gradually from rear to front, thus reducing a wind resistance and then reducing a loss of air volume. Here, the protective net body 411 may have a plurality of vertical ribs 4111. Any two vertical ribs 4111 may be parallel to each other, and alternatively, any two vertical ribs 4111 may be arranged at an included angle, which is not limited here.

[0071] In some examples of the invention, with reference to Figs. 1-3 and 6-8, the air outlet assembly 3 may be arranged on a front side of the protective net assembly 4. The air outlet assembly 3 includes a flow diversion cone 33 and a swing blade 34 rotatably arranged on the flow diversion cone 33. The protective net assembly 4 includes the protective net 41. The protective net 41 is at least partially concave to form an avoidance space 100 for avoiding the swing blade 34.

[0072] Through the above technical solution, the air flowing out of the cross-flow fan 1 may enter the air outlet assembly 3 through the protective net assembly 4. In this case, the swing blade 34 may change the flow direction of the air by rotation, and the flow diversion cone 33 may divert the air. Here, the arrangement of the avoidance space 100 may avoid interference between the swing blade 34 and the protective net assembly 4, so as to guarantee respective normal operation of the swing blade 34 and the protective net assembly 4, and achieve reasonable design of relative positions of the respective 34 and the protective net assembly 4.

[0073] According to some examples, when the protective net assembly 4 is disposed at the outlet 22 of the indoor unit, the swing blade 34 may be arranged on a front side of the protective net body 411. In this case, the swing blade 34 may change the flow direction of the air by rotation, for example, by up-down swing. During rotation of the swing blade 34, the arrangement of the avoidance space 100 may avoid collision between the protective net body 411 and the swing blade 34. According to some other examples, a distance between the swing blade 34 and the protective net body 411 may be no less than 3 mm-5 mm, so as to absorb an influence caused by assembly errors and manufacturing errors, and further avoid collision between the protective net body 411 and the swing blade 34.

[0074] In some examples of the invention, with reference to Figs. 1-3, 6 and 7, the flow diversion cone 33 may include a first flow diversion plate 331 and a second flow diversion plate 332 that are arranged to form an angle. The first flow diversion plate 331 and the second flow diversion plate 332 each are provided with the swing blade 34. The protective net 41 includes the protective net body 411. The protective net body 411 has a first net body 4113 and a second net body 4114 that are connected together. The first net body 4113 is provided with an avoidance space 100 for avoiding the swing blade 34 on the first flow diversion plate 331, and the second net body 4114 is provided with an avoidance space 100 for avoiding the swing blade 34 on the second flow diversion plate 332, that is to say, the first net body 4113 and the second net body 4114 separately form the avoidance spaces 100. In this way, the first net body 4113 and the second net body 4114 may avoid the corresponding swing blades 34 through the avoidance spaces 100 formed by the first net body and the second net body respectively, such that the indoor unit disclosed in the invention is suitable for being configured as a dual-air-outlet indoor unit. For example, the indoor unit may include the first air outlet 31 and the second air outlet 32. One swing blade 34 may be arranged on a rear side or upstream side of each of the first air outlet 31 and the second air outlet 32. The swing blades 34 may be partially arranged in the corresponding avoidance spaces 100.

[0075] In some examples of the invention, with reference to Figs. 1-3, 6 and 7, the protective net body 411 may be configured as M-shaped net by the first net body 4113 and the second net body 4114 jointly. That is to say, the protective net body 411 of the invention may form the two avoidance spaces 100 by its own M-shape, thus facilitating formation of the two avoidance spaces 100.

[0076] In some examples, with reference to Figs. 1-3, 6 and 7, a joint 4115 of the first net body 4113 and the second net body 4114 is located at a frontmost end of the protective net body 411. Here, the joint 4115 can be used to arrange the flow diversion member 42 conveniently. Moreover, since the joint 4115 is located at the frontmost end of the protective net 41, a flow diversion effect of the flow diversion member 42 can be guaranteed.

[0077] In some examples, with reference to Figs. 1-3, 6 and 7, the protective net body 411 is configured to be of a grid shape and has vertical ribs 4111 and horizontal ribs 4112 connected together. The first net body 4113 has at least three vertical ribs 4111 spaced in sequence in a left-right direction. In the three adjacent vertical ribs 4111, a frontmost end of the vertical rib 4111 located in the middle is arranged on a front side of frontmost ends of the vertical ribs 4111 located on two sides. In this way, in the example where the flow diversion member 42 is configured to guide the air flowing through the flow diversion member to flow leftwards and forwards, and in a case that the indoor unit has the first air outlet 31 and the second air outlet 32 located on the right side of the first air outlet 31, the middle vertical rib 4111 is arranged closer to a front side or a downstream side, such that the air passing through the middle vertical rib 4111 can flow forwards to the flow diversion member 42. In a case that the frontmost end of the middle vertical rib 4111 is arranged on a rear side of frontmost ends of the vertical ribs 4111 located on two sides, part of the air passing through the middle vertical rib 4111 is prevented from flowing directly to the second air outlet 32 without passing through the flow diversion member 42. Thus, the above arrangement is beneficial to uniform air outflow of the first air outlet 31 and the second air outlet 32. Here, in some examples, with reference to Figs. 1-3, 6 and 7, the second net body 4114 may have one vertical rib 4111, which is not limited here.

[0078] In some examples of the invention, with reference to Figs. 1-3, 6 and 7, the protective net 41 includes a protective net body 411. The protective net body 411 is configured to be of a grid shape and has a vertical rib 4111 and a horizontal rib 4112 connected together. The vertical rib 4111 may be understood as a rib arranged in an up-down direction. The vertical rib 4111 has a second upstream end 41111 and a second downstream end 41112. The second upstream end 41111 may has a width less than that of the second downstream end 41112. In this way, the wind resistance can be reduced to reduce the loss of air volume. It should be noted that the width of the second upstream end 41111 may be understood as a width of a cross section of the second upstream end 41111. Similarly, the width of the second downstream end 41112 may be understood as a width of a cross section of the second downstream end 41112.

[0079] In some examples of the invention, with reference to Figs. 1-3, 6 and 7, the horizontal rib 4112 has a third upstream end 41121 and a third downstream end 41122. The third upstream end 41121 may have a width less than that of the third downstream end 41122. In this way, the wind resistance can be reduced to reduce the loss of air volume. It should be noted that the width of the third upstream end 41121 may be understood as a width of a longitudinal section of the third upstream end 41121. Similarly, the width of the third downstream end 41122 may be understood as a width of a longitudinal section of the third downstream end 41122.

[0080] In some examples of the invention, with reference to Figs. 1-3, the air outlet assembly 3 may include a flow diversion bracket 35. The flow diversion bracket 35 and the flow diversion cone 33 define a first air outlet passage 200 and a second air outlet passage 300. The first air outlet passage 200 has the first air outlet 31. The second air outlet passage 300 has the second air outlet 32. The swing blade 34 is partially arranged in the first air outlet passage 200 or the second air outlet passage 300 correspondingly. Here, the first air outlet passage 200 and the second air outlet passage 300 defined by the flow diversion bracket 35 and the flow diversion cone 33 can implement a flow diversion function of the air outlet assembly 3. Specifically, after the air flowing out from the cross-flow fan 1 enters the air outlet assembly 3 through the protective net 41, the air is divided into the first air outlet passage 200 and the second air outlet passage 300 through the flow diversion bracket 35 and the flow diversion cone 33, such that the double-air-outlet design of the indoor unit is achieved. Here, the swing blade 34 is partially arranged in the first air outlet passage 200 or second air outlet passage 300 correspondingly, such that the swing blade 34 can conveniently change the flow direction of the air in the first air outlet passage 200 or second air outlet passage 300 correspondingly.

[0081] In some examples of the invention, with reference to Figs. 1-3, the first flow diversion plate 331 may be configured to define the first air outlet passage 200, and the second flow diversion plate 332 may be configured to define the second air outlet passage 300. The first flow diversion plate 331 is bent to have a first plate section 3311 and a second plate section 3312 that are connected to each other. The first plate section 3311 is connected to the second flow diversion plate 332. An included angle between the second plate section 3312 and the second flow diversion plate 332 is greater than an included angle between the first plate section 3311 and the second flow diversion plate 332. The swing blade 34 is connected to the second plate section 3312. Here, the swing blade 34 on the second plate section 3312 may be farther away from the protective net 41 than the first plate section 3311, and since the included angle between the second plate section 3312 and the second flow diversion plate 332 is greater than the included angle between the first plate section 3311 and the second flow diversion plate 332, such an arrangement may also arrange the swing blade 34 on the second plate section 3312 closer to the interior of the indoor unit, so as to facilitate the compact design of the indoor unit.

[0082] In some examples, with reference to Figs. 1-3, the swing blade 34 has a rotating shaft 341, and a rotating axis of the rotating shaft 341 is horizontally arranged and is perpendicular to the second plate section 3312 or the second flow diversion plate 332 correspondingly. In this way, up-down swing of the swing blade 34 may be implemented.

[0083] In some examples of the invention, with reference to Figs. 1-3, the flow diversion cone 33 has a tip end 333. The tip end 333 is aligned with the first downstream end 422 in a left-right direction. In this way, it is advantageous for the flow diversion cone 33 to divert the air flowing towards the flow diversion cone.

[0084] In some examples of the invention, with reference to Figs. 1-3 and 6, the protective net assembly 4 includes a protective net 41 and a flow diversion member 42. The protective net 41 and the flow diversion member 42 may be formed integrally.

[0085] Through the above technical solution, in the protective net assembly 4 provided in the invention, integrated formation of the protective net 41 and the flow diversion member 42 can reduce the number of parts of the protective net assembly 4, so as to simplify assembly steps of the protective net assembly 4. Similarly, such the arrangement can also reduce the number of parts of the indoor unit, so as to simplify the assembly steps of the indoor unit.

[0086] It should be noted that the protective net assembly 4 of the invention can be configured as an integrally formed part, which is not limited here. For example, the protective net assembly 4 may be integrally molded by extrusion. Here, the protective net assembly 4 may be made of a plastic material, which can also reduce manufacturing cost of the protective net assembly 4. Compared with the protective net assembly 4 made of a metal material, the protective net assembly 4 made of a plastic material may also avoid abnormal noise generated by the indoor unit during heating, such that user experience is improved.

[0087] It should also be noted that the flow diversion member 42 of the invention may be understood as a part that may achieve flow division by changing a flow direction of air, which will be described in detail in the following examples of the invention. Moreover, since the protective net 41 and the flow diversion member 42 are formed integrally, the protective net 41 and the flow diversion member 42 may be arranged at substantially the same position in the indoor unit. Thus, a flow diversion function of the flow diversion member 42 and a false touch prevention function of the protective net 41 can be advantageously juggled . Here, the false touch prevention function refers to that the protective net 41 can prevent a user from falsely touching the cross-flow fan 1 of the indoor unit.

[0088] In some examples of the invention, with reference to Figs. 1-3, the protective net 41 includes a protective net body 411. The protective net body 411 may have a first net body 4113 and a second net body 4114 that are connected together. The protective net body 411 is configured as an M-shaped net by the first net body 4113 and the second net body 4114 jointly. The flow diversion member 42 is connected to a joint 4115 of the first net body 4113 and the second net body 4114. Here, the joint 4115 can be used to arrange the flow diversion member 42 conveniently. Moreover, since the joint 4115 is located at the frontmost end of the protective net 41, a flow diversion effect of the flow diversion member 42 can be guaranteed.

[0089] In some examples of the invention, with reference to Figs. 6 and 8-10, the protective net 41 includes a frame body 43 and a protective net body 411 arranged in the frame body 43. The frame body 43 has an upper frame 431 and a lower frame 432. Both the upper frame 431 and the lower frame 432 may have bosses 433. The flow diversion member 42 is connected to the protective net body 411. An upper end and a lower end of the flow diversion member 42 are connected to the corresponding bosses 433 respectively. Here, the bosses 433 may provide a mounting base for the upper end or the lower end of the flow diversion member 42, such that connection strength between the bosses 433 and the protective net 41 is improved.

[0090] In some examples of the invention, with reference to Fig. 10, at least one of the two bosses 433 may be further provided with a mounting platform 434. The mounting platform 434 is configured to overlap the flow diversion bracket 35 of the indoor unit. In this way, by using overlapping of the mounting platform 434 and the flow diversion bracket 35, it is convenient to arrange a sealing structure at an overlapping position of the mounting platform 434 and the flow diversion bracket 35, so as to achieve sealed connection between the upper frame 431 or the lower frame 432 and the flow diversion bracket 35.

[0091] In some examples of the invention, with reference to Figs. 7, 12 and 13, the protective net assembly 4 includes a protective net 41 and a flow diversion member 42. The flow diversion member 42 is detachably connected to the protective net 41.

[0092] Through the above technical solution, in the protective net assembly 4 provided in the invention, the flow diversion member 42 is configured to be detachably connected to the protective net 41, that is, the protective net 41 and the flow diversion member 42 are two separate parts. In this way, compared with a manner that the protective net 41 and the flow diversion member 42 are formed integrally, a material, shape, etc. of the flow diversion member 42 may be independently designed without considering the protective net 41, such that the flow diversion member 42 has higher structural strength. Accordingly, in a case that the flow diversion member 42 is connected to the protective net 41, the flow diversion member 42 is not easily deformed when air flows through the flow diversion member 42, and when the air deforms the protective net 41, the deformation of the protective net 41 is unlikely to deform the flow diversion member 42. Thus, the protective net assembly 4 of the invention can solve the technical problem that the flow diversion member 42 is likely to deform.

[0093] It should be noted that the invention does not limit a specific detachable connection manner between the flow diversion member 42 and the protective net 41, which will be described in detail in the following examples of the invention.

[0094] In some examples of the invention, the flow diversion member 42 may be made of a metal material. In this way, compared with the flow diversion member 42 made of a plastic material, the flow diversion member 42 made of a metal material has higher structural strength and is less likely to deform. Here, the flow diversion member 42 may be made of aluminum, which is not limited here.

[0095] In some examples of the invention, with reference to Figs. 7, 12 and 13, the protective net 41 may include a frame body 43 and a protective net body 411 arranged in the frame body 43. The flow diversion member 42 is detachably connected to the frame body 43. The flow diversion member 42 is spaced from the protective net body 411. Here, the protective net body 411 may be deformed by the air. In this case, since the flow diversion member 42 is spaced from the protective net body 411, the deformation of the protective net body 411 can be prevented from being transmitted to the flow diversion member 42. Thus, such an arrangement can effectively avoid deformation of the flow diversion member 42, improve stability and reliability of the flow diversion member 42, and avoid abnormal noise caused by the deformation of the flow diversion member 42.

[0096] In some examples of the invention, with reference to Figs. 12-14, the frame body 43 may have an upper frame 431 and a lower frame 432. Both the upper frame 431 and the lower frame 432 have limiting holes 435. An upper end and a lower end of the flow diversion member 42 penetrate the corresponding limiting holes 435 respectively. The lower end of the flow diversion member 42 further extends out of the lower frame 432, such that limiting can be provided for the flow diversion member 42 through the limiting holes 435. The protective net assembly 4 may include a compression cover 44. The compression cover 44 has a fixing hole 441. The fixing hole 441 is connected to the flow diversion member 42 in an interference fit manner. The compression cover 44 is detachably connected to the lower frame 432. In this way, through the interference fit between the fixing hole 441 and the flow diversion member 42, the compression cover 44 may be fixedly connected to the flow diversion member 42. Through connection between the compression cover 44 and the lower frame 432, the flow diversion member 42 may be assembled with the protective net 41, the structure is simple, and operation is convenient.

[0097] In some examples of the invention, with reference to Figs. 12-14, the lower frame 432 may be provided with a connection column 436. The connection column 436 has a threaded hole in threaded connection to a fastener. The compression cover 44 has a through hole 442 fitted to the connection column 436. In this way, the compression cover 44 and the connection column 436 may be fixed by the threaded connection between the fastener and the threaded hole, and the reliability is high. Certainly, in other examples of the invention, the compression cover 44 may also be clamped on the lower frame 432. For example, one of the compression cover 44 and the lower frame 432 may be provided with a buckle, and the other may be provided with a clamp groove. The detachable connection between the compression cover 44 and the lower frame 432 is achieved through clamping of the buckle and the clamp groove.

[0098] In some examples of the invention, as shown in Fig. 13, the limiting hole 435 of the upper frame 431 may be configured as a blind hole. In this way, the upper frame 431 may also provide downward limitation for the flow diversion member 42.

[0099] In some examples, with reference to Figs. 13 and 14, the upper frame 431 and the lower frame 432 are provided with bosses 433 separately. The bosses 433 may be provided with limiting holes 435. In this way, the bosses 433 may also provide a mounting base for the flow diversion member 42. Furthermore, compared with increasing a size of the upper frame 431 or the lower frame 432 as a whole, adding the bosses 433 can also reduce a volume and weight of the upper frame 431 or the lower frame 432, which is advantageous to compact design of the indoor unit.

[0100] In some examples, with reference to Figs. 13 and 14, the limiting holes 435 may further extend into the upper frame 431 or the lower frame 432 correspondingly. In this way, the upper frame 431 and the lower frame 432 may also be used to provide a mounting base for the flow diversion member 42. Moreover, the upper frame 431 or the lower frame 432 may be used to arrange the limiting holes 435, so as to be adapted to the flow diversion members 42 with different sizes.

[0101] In some examples, with reference to Fig. 12, the boss 433 on the upper frame 431 may be further provided with a mounting platform 434. The mounting platform 434 is configured to overlap the flow diversion bracket 35 of the indoor unit. In this way, by using overlapping of the mounting platform 434 and the flow diversion bracket 35, it is convenient to arrange a sealing structure at an overlapping position of the mounting platform 434 and the flow diversion bracket 35, so as to achieve sealed connection between the upper frame 431 and the flow diversion bracket 35.

[0102] In some examples of the invention, with reference to Figs. 1-3 and 9-13, the air outlet assembly 3 may include a flow diversion bracket 35. The protective net 41 may include a frame body 43 and a protective net body 411 arranged in the frame body 43. A connection structure 45 is arranged on the frame body 43. The frame body 43 is detachably connected to the flow diversion bracket 35 through the connection structure 45. In this way, the protective net 41 and the flow diversion bracket 35 may be disassembled and assembled through the connection structure 45, such that the assembly and disassembly of the protective net assembly 4 and the flow diversion bracket 35 is convenient. Here, the invention does not limit a specific structure of the connection structure 45, which will be described in detail in the following examples of the invention.

[0105] In some examples of the invention, with reference to Figs. 9-13, the connection structure 45 may include connection plates 452 arranged on the left side and the right side of the frame body 43 respectively. The connection plates 452 have through holes allowing fasteners to penetrate. The connection plates 452 are detachably connected to the flow diversion bracket 35 through fasteners. In this way, the protective net 41 is detachably fixed to the flow diversion bracket 35 through fitting of the connection plates 452 and the fasteners, such that reliability of connection between the protective net 41 and the flow diversion bracket 35 is improved. Here, the flow diversion bracket 35 may be provided with a threaded hole fitted to a fastener, which is not limited here.

[0106] In some examples of the invention, with reference to Figs. 9-13, the plurality of connection plates 452 spaced in an up-down direction may be arranged on the left side and the right side of the frame body 43 respectively. In this way, the stability of the connection between the protective net 41 and the flow diversion bracket 35 may be improved, and connection strength between the protective net and the flow diversion bracket may be improved.

[0107] In some examples, with reference to Figs. 9-13, any of the connection plates 452 is arranged between two different adjacent slide fasteners 451. In this way, fixing points between the protective net 41 and the flow diversion bracket 35 may be arranged scattered, and insertion points between the protective net 41 and the flow diversion bracket 35 may be arranged scattered, such that the stability of the connection between the protective net 41 and the flow diversion bracket 35 is improved.

[0108] In some examples of the invention, with reference to Figs. 1-3, 8 and 9, the protective net 41 includes a frame body 43. The protective net body 411 is arranged in the frame body 43. The flow diversion bracket 35 and the air duct assembly 2 may jointly clamp the frame body 43. In this way, it is advantageous for the relative stability of the position of the protective net 41 and preventing the protective net 41 from shifting and offsetting.

The first insertion portion 4371 has a second body portion 4372 and a second protrusion 4373 arranged on the second body portion 4372. The second protrusion 4373 and the second body portion 4372 define a second insertion groove 4374. The first projection 3522 is inserted into the second insertion groove 4374 in a shape-fitting manner. The second projection 4373 is inserted into the first insertion groove 3523 in a shape-fitting manner. In this way, the left frame 437 may be inserted into the first wall plate 352 in a shape-fitting manner. Accordingly, a sealing structure may be conveniently arranged between the left frame 437 and the first wall plate 352 to prevent air leakage.

[0110] In some examples of the invention, with reference to Figs. 3, 4, 6 and 7, the first protrusion 3522 shares a first wall surface 3524 with the first insertion groove 3523. The second protrusion 4373 shares a second wall surface 4375 with the second insertion groove 4374. The first wall surface 3524 is attached to the second wall surface 4375. The first wall surface 3524 obliquely extends leftwards gradually from rear to front. In this way, the first wall surface 3524 and the second wall surface 4375 are attached to each other to prevent air leakage. The first wall surface 3524 is arranged to obliquely extend leftwards gradually from rear to front to facilitate insertion of the left frame 437 into the flow diversion bracket 35.

[0112] In some examples of the invention, with reference to Figs. 1-3, 4, 6 and 7, the frame body 43 has a left frame 437 and a right frame 438. The air duct assembly 2 has a third wall plate 23 for defining the guide passage 21. The third wall plate 23 has a third wall surface 231. The left frame 437 has a fourth wall surface 4376 attached to the third wall surface 231. The fourth wall surface 4376 obliquely extends leftwards gradually from rear to front. In this way, the third wall surface 231 and the fourth wall surface 4376 are attached to each other to prevent air leakage. The fourth wall surface 4376 is arranged to obliquely extend leftwards gradually from rear to front to facilitate assembly of the left frame 437 with the air duct assembly 2.

In this way, the fifth wall surface 241 and the sixth wall surface 4382 are attached to each other to prevent air leakage.

[0114] In some examples of the invention, with reference to Figs. 8-10, the left side and the right side of the flow diversion bracket 35 may be provided with overlap buckles 354 respectively. The overlap buckles 354 are configured to overlap in overlap grooves 25 of the air duct assembly 2 of the indoor unit. In this way, pre-assembly of the air duct assembly 2 with the flow diversion bracket 35 may be implemented by overlap of the overlap buckles with the overlap grooves 25.

[0115] In some examples of the invention, with reference to Figs. 8-10, the plurality of overlap buckles 354 spaced in an up-down direction may be arranged on the left side and the right side of the flow diversion bracket 35 respectively.

Here, the air duct assembly 2 may be provided with a threaded hole fitted to a fastener, which is not limited here.

[0117] In the below, a specific working process of the indoor unit will be described in detail in combination with the above specific examples in the invention. With reference to Figs. 1-3, firstly, with rotation of the cross-flow fan 1, air may enter the guide passage 21, and flow out of the outlet 22 rightwards from rear to front gradually through guide of the guide passage 21. In this case, a part of the air may pass through the protective net body 411 to flow rightwards and forwards and flow out from the second air outlet 32, and another part of the air may pass through the protective net body 411, flow leftwards and forwards through guide of the flow diversion member 42, and flow out from the first air outlet 31, such that the double-air-outlet design of the indoor unit is achieved. In this process, since the first upstream end 421 of the flow diversion rib is arranged close to the right, more air flowing at a lower flow velocity flows to the first air outlet 31 through the guide of the flow diversion member 42, and less air flowing at a higher flow velocity flows rightwards and forwards to the first air outlet 31. In this case, such an arrangement can achieve uniform air outflow of the first air outlet 31 and the second air outlet 32.

[0118] In the below, a specific working process of the indoor unit will be described in detail in combination with the above specific examples in the invention. Here, the indoor unit may further include a front housing 5 and a rear housing 6. During assembly, with reference to Figs. 1, 8 and 9, the cross-flow fan 1 and the air duct assembly 2 may be mounted on the rear housing 6 first, and then the flow diversion cone 33 and the flow diversion bracket 35 may be connected together.
