[0007] In one embodiment of this utility model, the motor mounting part includes: a motor compartment, in which a drive assembly is installed, and a first wire guide is provided at the opening of the motor compartment; a motor cover, which is located at the opening, and a second wire guide is provided on the side of the motor cover away from the motor compartment; wherein the first wire guide and the second wire guide cooperate to form a wire guide structure.

[0008] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by separately setting the wire-passing structure on the motor cover and the motor housing, the electrical connection wires of the drive component can be constrained in the wire-passing structure while the motor cover is placed on the motor housing, saving the time of separately placing the electrical connection wires into the wire-passing structure.

[0009] In one embodiment of this utility model, the first wire guide portion includes: a first side plate, which is disposed on the side of the motor compartment near the motor cover; and a second side plate, which is disposed opposite to the first side plate.

[0010] Compared with the existing technology, the technical effect achieved by adopting this technical solution is that, through the first side plate and the second side plate arranged opposite to each other on the motor compartment, the electrical connection wire can be placed in the corresponding position of the first wire passage more conveniently before the motor cover is placed on the motor compartment, which facilitates the operation of the user.

[0011] In one embodiment of this utility model, the second wire guide portion includes: a third side plate, which is disposed on the side of the motor cover away from the motor compartment; wherein the first side plate, the second side plate and the third side plate surround a wire harness channel forming a wire guide structure.

[0012] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: by setting a third side plate on the motor cover, when the motor cover is placed on the motor compartment, the third side plate, the first side plate, and the second side plate form a wire harness channel, so that the two steps of placing the motor cover on the motor compartment and placing the electrical connection wire into the wire harness channel of the wire structure are achieved simultaneously, thereby saving time for users.

[0013] In one embodiment of this utility model, a first positioning groove is provided on the side of the second side plate near the third side plate; a first positioning member that cooperates with the first positioning groove is provided on the side of the third side plate near the second side plate to restrict the sliding of the second side plate and the second side plate relative to each other.

[0016] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: Due to the structural limitations of the third side plate itself, the stability of the third side plate on the motor cover is not high enough. By setting several reinforcing ribs on the side of the third side plate away from the second side plate, on the one hand, the stability of the second wire passage itself is enhanced; on the other hand, it also makes the reinforcing ribs and the wire harness channel not set on the same side, thereby affecting the routing of the electrical connection wires in the wire harness channel.

[0017] In one embodiment of this utility model, the motor compartment has several fixed protrusions on its periphery; the motor cover has several fixed buckles that cooperate with the fixed protrusions on its periphery, so that the motor cover is snapped onto the top of the motor compartment.

[0040] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0041] See Figures 1 to 9 This utility model provides an indoor unit 1, which includes a housing assembly 10, an air guide assembly 20, and a wiring structure. The housing assembly 10 has an air outlet; the air guide assembly 20 is disposed in the air outlet chamber 11 of the housing assembly 10 forming the air outlet. Both the air guide assembly 20 and the air outlet chamber 11 are elongated, and one end of the air guide assembly 20 has a motor mounting part for mounting a drive assembly 50; the wiring structure is disposed in the fitting gap between the motor mounting part and the side wall of the air outlet chamber 11, for the passage of the electrical connection wire 51 of the drive assembly 50. After passing through the wiring structure, the electrical connection wire 51 passes through the side wall of the air outlet chamber 11 and then connects to the electrical control box 70. By providing a wiring structure between the motor mounting part and the side wall of the air outlet, the electrical connection wire 51 of the drive assembly 50 can be protected by the wiring structure, improving its fault tolerance; and by providing a wiring structure, when looking at the indoor unit 1 from the outside, the motor wire is no longer exposed, improving its aesthetics.

[0042] Preferably, the motor mounting section includes a motor housing 30 and a motor cover 40. The drive assembly 50 is installed in the motor housing space. The motor housing 30 is located at the air outlet of the indoor unit 1. The motor housing 30 has a housing space for installing the drive assembly 50 and an opening communicating with the housing space. A first wire guide 100 is provided at the opening of the motor housing 30. The motor cover 40 is located at the opening. A second wire guide 200 is provided on the side of the motor cover 40 away from the motor housing 30. The first wire guide 100 and the second wire guide 200 are complementary structures. The first wire guide 100 and the second wire guide 200 cooperate to form a wire guide structure for constraining the electrical connection wire 51 of the drive assembly 50. The electrical connection wire 51 of the drive assembly 50 extends from the wire guide structure and connects to other components inside the indoor unit 1. By separately setting the wire-passing structure on the motor cover 40 and the motor compartment 30, the electrical connection wire 51 of the drive assembly 50 can be constrained in the wire-passing structure while the motor cover 40 is placed on the motor compartment 30, saving the time of separately placing the electrical connection wire 51 into the wire-passing structure.

[0043] Preferably, the first wire guide portion 100 includes a first side plate 110 and a second side plate 120. The first side plate 110 is disposed on the motor housing 30 near the motor cover 40. The second side plate 120 is disposed opposite to the first side plate 110, and the second side plate 120 is shorter than the first side plate 110. The distance between the first side plate 110 and the second side plate 120 is larger than the electrical connection line 51 of the drive assembly 50, so as to constrain the electrical connection line 51. Specifically, the first side plate 110 and the second side plate 120 have a slight included angle to adjust the constraint effect of the wire guide structure on the electrical connection line 51.

[0044] With the first side plate 110 and the second side plate 120 arranged opposite to each other on the motor compartment 30, the electrical connection wire 51 can be placed in advance at the corresponding position of the first wire passage 100 before the motor cover 40 is placed on the motor compartment 30, which makes it easier for the user to operate.

[0045] Furthermore, the second wire guide section 200 also includes a third side plate 210, which is disposed on the side of the motor cover 40 away from the motor compartment 30. The first side plate 110, the second side plate 120, and the third side plate 210 form a wire harness channel, and the two ends of the third side plate 210 are respectively connected to the first side plate 110 and the second side plate 120 to form a complete closed channel. The third side plate has a slight curvature to accommodate the angle between the first side plate 110 and the second side plate 120. By providing the third side plate 210 on the motor cover 40, when the motor cover 40 is placed on the motor compartment 30, the third side plate 210, the first side plate 110, and the second side plate 120 form a wire harness channel. This allows the two steps of placing the motor cover 40 on the motor compartment 30 and placing the electrical connection wire 51 into the wire harness channel of the wire guide structure to be achieved simultaneously, thus saving time for the user.

[0046] Specifically, the second side plate 120 has a first positioning groove 121 on the side near the third side plate 210; the third side plate 210 has a first positioning member 211 on the side near the second side plate 120 that cooperates with the first positioning groove 121 to restrict the sliding of the second side plate 120 and the second side plate 120 relative to each other; since the second side plate 120 is shorter than the first side plate 110, the first positioning member 211 protrudes from the third side plate 210 so that the first positioning member 211 and the first positioning groove 121 can cooperate. Through the cooperation of the first positioning groove 121 and the first positioning member 211, after the motor cover 40 is placed on the motor compartment 30, the wire-passing structure can be made more stable, the wire-passing structure is not easy to deform, and the electrical connection wire 51 is not easy to come out in the wire-passing channel.

[0047] In addition, the second wire guide section 200 also includes several reinforcing ribs 220. The reinforcing ribs 220 are located on the side of the third side plate 210 away from the second side plate 120. The reinforcing ribs 220 are triangular plate-shaped ribs to improve the stability of the reinforcing ribs 220. Furthermore, several reinforcing ribs 220 can also be provided on the outer side of the first side plate 110 and the second side plate 120 to improve the overall strength of the wire guide structure. Due to the structural limitations of the third side plate 210 itself, the stability of the third side plate 210 on the motor cover 40 is not high enough. By providing several reinforcing ribs 220 on the side of the third side plate 210 away from the second side plate 120, on the one hand, the stability of the second wire guide section 200 itself is enhanced; on the other hand, it also ensures that the reinforcing ribs 220 and the wire harness channel are not located on the same side, thereby affecting the routing of the electrical connection wire 51 in the wire harness channel.

[0048] Preferably, the motor housing 30 has a plurality of fixing protrusions 31 on its periphery, which are evenly distributed along the periphery of the motor housing 30; the motor cover 40 has a plurality of fixing buckles 41 on its periphery that cooperate with the fixing protrusions 31, so that the motor cover 40 is snapped onto the top of the motor housing 30, and the fixing buckles 41 are also evenly distributed around the motor cover 40. Through the cooperation of the fixing protrusions 31 and the fixing buckles 41, the motor cover 40 can be detachably installed on the motor housing 30; on the other hand, the even distribution of the buckles along the circumference of the motor housing 30 can improve the stability of the motor cover 40 installed on the motor housing 30, so that the fixing buckles 41 and the fixing protrusions 31 will not easily detach.

[0049] Furthermore, the first wire guide portion 100 also includes a motor shaft seat 130. The motor shaft seat 130 is circular and is located at the edge of the opening of the motor compartment 30 to reduce its impact on the opening. The motor shaft seat 130 is located on the side of the second side plate 120 away from the third side plate 210 and is connected to the first side plate 110 and the second side plate 120 respectively. The side of the motor shaft seat 130, together with the first side plate 110, the second side plate 120, and the third side plate 210, forms a wire harness channel. By incorporating the motor shaft seat 130 as part of the wire guide structure, on the one hand, it saves the material and space required for the side wall of the separate wire guide structure, facilitating industrial manufacturing; on the other hand, the stability of the first wire guide portion 100 is improved by the motor shaft seat 130, which acts as a reinforcing rib 220.

[0050] In addition, the indoor unit 1 also includes an adapter plate 60, which is installed inside the air outlet of the indoor unit 1. The adapter plate 60 is located on the side of the motor cover 40 away from the motor compartment 30. The adapter plate 60 has a clearance groove 61 that is opposite to the wiring structure. A wire harness buckle 62 is also provided on the side of the adapter plate 60 away from the motor cover 40. The wire harness channel, the clearance groove 61, and the wire harness buckle 62 form a wiring channel for constraining the electrical connection wire 51. The electrical connection wire 51 is connected to the electrical control box 70 of the indoor unit 1 through the wiring channel. By constructing a wiring channel inside the indoor unit 1, the electrical connection wire 51 is arranged more reasonably inside the indoor unit 1 and will not be scattered.

[0051] Furthermore, the clearance groove 61 is fan-shaped, and its size is larger than that of the wiring structure, so that the wiring structure can slide within the clearance groove 61. Simultaneously, the shape of the clearance groove 61 is designed to fit the shape of the wiring structure, thus limiting the sliding range of the wiring structure within the clearance groove 61. When the wiring structure is placed within the clearance groove 61, by making the clearance groove 61 fan-shaped, the transmission problem of the air guide plate connected to the motor compartment 30 inside the indoor unit 1 is solved, and the wiring route problem inside the indoor unit 1 is also solved, achieving multiple benefits in one fell swoop.

[0052] This utility model also provides an air conditioner, including the indoor unit 1 of any of the above.

[0053] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
