[0045] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0046] The following is for reference. Figures 1-13 This invention describes an air conditioner according to an embodiment of the present invention.

[0047] An air conditioner according to an embodiment of the present invention includes: a housing assembly 10, a heat exchanger assembly 20, an air duct assembly 40, and an electrical control box component.

[0048] Reference Figure 1 and Figure 2 The front of the housing assembly 10 has two air outlets 11 arranged in the left-right direction, and the rear of the housing assembly 10 has an air inlet 12. By having two air outlets 11 spaced apart in the left-right direction, the air outlet range of the air conditioner can be increased.

[0049] The heat exchanger assembly 20 is disposed within the housing assembly 10 and includes a heat exchanger component 21 and an electric auxiliary heating component 22. By including the electric auxiliary heating component 22 in the heat exchanger assembly 20, the electric auxiliary heating component 22 can improve the heat exchange efficiency of the air conditioner by heating it with electricity. For example, when the air conditioner is in heating mode, the electric auxiliary heating component 22 is energized and assists the heat exchanger assembly 20 in heating, thereby improving the air conditioner's ability to heat the airflow and enhancing its heating capacity.

[0050] The air duct assembly 40 is located within the housing assembly 10 and includes an air duct volute 41 and a fan assembly 42. The air duct volute 41 has two air ducts 43 arranged in a left-right direction, and two air outlets 11 are respectively connected to the two air ducts 43. The fan assembly 42 includes two fans 44 arranged in a left-right direction. Each fan 44 includes a fan wheel 45 and a motor 46, with the motor 46 connected to the fan wheel 45. The two fan wheels 45 are located within the two air ducts 43 respectively. By making the air duct volute 41 include two front volutes, and the fan assembly 42 include two fans 44 arranged in a left-right direction, with the fan wheels 45 of the two fans 44 respectively located within the two air ducts 43, the air conditioner's air-driving capability can be improved, thus enhancing its performance. By making the front volute and the air duct 43 partition detachably connected, the installation and removal of the air conditioner can be made more convenient for relevant personnel.

[0051] The electrical control box is located within the housing assembly 10 and below the air duct assembly 40. The wiring harness connected to the electric auxiliary heating component 22 is an electric auxiliary heating harness 60. The electric auxiliary heating harness 60 is connected to the electrical control box and includes a first harness segment 61 that runs vertically. The first harness segment 61 is located at one end of the air duct housing 41 in the horizontal direction. By placing the first harness segment 61 at one end of the air duct housing 41 in the horizontal direction, the electric auxiliary heating harness 60 can be routed through one end of the air duct housing 41 in the horizontal direction, increasing the distance between the electric auxiliary heating harness 60 and the low-voltage wiring harness, thereby preventing the electric auxiliary heating harness 60 from interfering with the signals transmitted by other low-voltage wiring harnesses.

[0052] For example, the first wire harness segment 61 can be located at the left end of the air duct volute 41, and the low-voltage wire harness can run from the central part of the air duct volute 41, thereby increasing the distance between the high-voltage wire harness and the low-voltage wire harness and reducing the influence of the electric auxiliary heating wire harness 60 on the signal of the low-voltage wire harness.

[0053] According to the embodiment of the present invention, the heat exchanger assembly 20 of the air conditioner includes an electric auxiliary heating component 22. By positioning the first section 61 of the electric auxiliary heating wire harness 60 at one end of the air duct volute 41 in the left-right direction, the electric auxiliary heating wire harness 60 can be routed from one end of the air duct volute 41 in the left-right direction, optimizing the routing path of the electric auxiliary heating wire harness 60, increasing the distance between the electric auxiliary heating wire harness 60 and other wire harnesses, reducing the interference of the electric auxiliary heating wire harness 60 to other wire harnesses, and reducing the risk of air conditioner malfunction.

[0054] According to some embodiments of the present invention, referring to Figures 3-6 The air duct housing 41 has a wiring groove 51 extending vertically at one end along the left-right direction, and the first wire harness segment 61 is accommodated in the wiring groove 51. By accommodating the first wire harness segment 61 in the wiring groove 51, the first wire harness segment 61 can be neatly routed, preventing the first wire harness segment 61 from getting tangled or affecting other components.

[0055] According to some embodiments of the present invention, referring to Figure 5 and Figure 6 The duct housing 41 is provided with multiple wire clamps 52 arranged at intervals along the vertical direction. The wire clamps 52 are located at the open opening of the cable tray 51 to limit the first wire harness segment 61. By providing wire clamps 52 on the duct housing 41 to limit the first wire harness segment 61, the first wire harness segment 61 can be prevented from getting tangled or affecting other components. By having multiple wire clamps 52, and by arranging them at intervals along the vertical direction of the duct housing 41, the first wire harness segment 61 can be limited by the wire clamps 52 in both the vertical and horizontal directions, making the limiting effect of the wire clamps 52 more sufficient. By placing the wire clamps 52 at the open opening of the cable tray 51, the installation and fixing of the first wire harness segment 61 can be made more convenient. For example, the wire clamps 52 have a certain degree of elasticity. When installing the first wire harness segment 61, the wire clamps 52 can be elastically deformed and the first wire harness segment 61 can be placed into the cable tray 51 from the open opening.

[0056] According to some embodiments of the present invention, referring to Figure 5 and Figure 6 The first wiring harness segment 61 is located on the front side of the air duct volute 41. By placing the first wiring harness segment 61 on the front side of the air duct volute 41, the influence of the heat exchanger 24 on the first wiring harness segment 61 can be avoided, and it is also convenient to connect the electric auxiliary heating component 22 located on the upper side of the air conditioner to the control center on the lower side.

[0057] For example, when the air conditioner is in cooling mode, the temperature near the heat exchanger 24 is low. If the distance between the first wiring harness segment 61 and the heat exchanger 24 is too close, a lot of water droplets may condense on the first wiring harness segment 61. By placing the first wiring harness segment 61 in front of the air duct volute 41, the accumulation of water droplets on the first wiring harness segment 61 can be avoided, thus preventing danger. When the air conditioner is in heating mode, the temperature of the heat exchanger 24 is high. If the distance between the first wiring harness segment 61 and the heat exchanger 24 is too close, the aging rate of the first wiring harness segment 61 will be accelerated. By placing the first wiring harness segment 61 in front of the air duct volute 41, the lifespan of the first wiring harness segment 61 can be extended.

[0058] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 The electric auxiliary heating harness 60 includes a second harness segment 62, which is located above the air duct housing 41 and connects the first harness segment 61 to the electric auxiliary heating component 22. By positioning the second harness segment 62 above the air duct housing 41, it is easier to arrange the second harness segment 62, resulting in neater wiring and shorter wiring distances.

[0059] According to some embodiments of the present invention, referring to Figure 3 and Figure 4The top of the duct housing 41 is provided with a motor cover 53, and the motor cover 53 has a motor cavity 54 for accommodating the motor 46. At least a portion of the second wiring harness segment 62 runs along the top of the motor cover 53. By providing a motor cover 53 on the top of the duct housing 41, the motor 46 can be accommodated in the motor cavity 54, and the motor cover 53 protects the motor 46, preventing damage caused by collisions with other components. By having at least a portion of the first wiring harness segment 61 run along the top of the motor cover 53, the arrangement of the second wiring harness segment 62 can be facilitated, making the wiring of the second wiring harness segment 62 more regular and the wiring distance shorter.

[0060] According to some embodiments of the present invention, referring to Figure 4 The top of the motor cover 53 is provided with a first wiring buckle 55, and the first wiring buckle 55 has a first wiring hole 56. The second wire harness segment 62 passes through the first wiring hole 56. By providing a first wiring buckle 55 on the top of the motor cover 53 and allowing the second wire harness segment 62 to pass through the first wiring hole 56, the first wiring buckle 55 can be used to limit the wiring, making the wiring neat.

[0061] According to some embodiments of the present invention, referring to Figures 3-6 The duct housing 41 has a wiring groove 51 extending vertically at one end in the left-right direction. The first wire harness segment 61 is accommodated in the wiring groove 51. In the left-right direction, the first wiring buckle 55 is located at the end of the motor cover 53 adjacent to the wiring groove 51. By providing a wiring groove 51 extending vertically at one end in the left-right direction of the duct housing 41 and accommodating the first wire harness segment 61 in the wiring groove 51, the wiring of the first wire harness segment 61 can be made neat, preventing the first wire harness segment 61 from getting tangled or affecting other components. By placing the first wiring buckle 55 at the end of the motor cover 53 adjacent to the wiring groove 51 in the left-right direction, the wiring of the second wire harness segment 62 can be made closer to the first wire harness segment 61, making it easier to connect the second wire harness segment 62 to the first wire harness segment 61.

[0062] For example, refer to Figure 3 The wiring trough 51 is located on the right side of the air duct volute 41. The wiring trough 51 extends in the vertical direction. The first wiring buckle 55 is located on the right side of the motor cover 53 and on the upper side of the motor cover 53. The second wire harness segment 62 passes through the first wiring hole 56 and is connected to both the first wire harness segment 61 and the electric auxiliary heating component 22.

[0063] According to some embodiments of the present invention, referring to Figure 4 and Figure 9The heat exchanger component 21 includes a heat exchanger bracket 23 and a heat exchanger 24. Both the heat exchanger 24 and the electric auxiliary heating component 22 are mounted on the heat exchanger bracket 23. A wire hole 25 is provided at the top of the heat exchanger bracket 23. The electric auxiliary heating harness 60 includes a third harness segment 63, which connects the second harness segment 62 to the electric auxiliary heating component 22. The third harness segment 63 passes through the wire hole 25. By including the third harness segment 63 in the electric auxiliary heating harness 60, the third harness segment 63 can be connected to the electric auxiliary heating component 22, facilitating the connection between them. Furthermore, by providing the wire hole 25 at the top of the heat exchanger bracket 23 and allowing the third harness segment 63 to pass through the wire hole 25, the wire hole 25 can limit the movement of the third harness segment 63 within the air conditioner.

[0064] According to some embodiments of the present invention, referring to Figure 7 and Figure 13 The electric auxiliary heating harness 60 includes a fourth harness segment 64, which connects the first harness segment 61 to the electrical control box component. The bottom surface of the heat exchanger assembly 20 is provided with a water receiving tray 30. At least one second wiring buckle 32 is provided at the front end of the water receiving tray 30. The second wiring buckle 32 has a second wiring hole 31, through which the fourth harness segment 64 passes. By including the fourth harness segment 64 in the electric auxiliary heating harness 60 and connecting the first harness segment 61 to the electrical control box component, the connection between the electric auxiliary heating component 22 and the electrical control box component is facilitated. By providing the second wiring buckle 32 at the front end of the water receiving tray 30 and allowing the fourth harness segment 64 to pass through the second wiring hole 31, the second wiring hole 31 can limit the movement of the fourth harness segment 64.

[0065] According to some embodiments of the present invention, referring to Figure 7 and Figure 13 The water receiving tray 30 is provided with a wiring protrusion 33, which is located at the front end of the water receiving tray 30. Multiple second wiring clips 32 are provided, some on the wiring protrusion 33 and some on the front side wall of the water receiving tray 30. By providing the wiring protrusion 33 within the water receiving tray 30, the wiring position of the fourth wire harness segment 64 can be raised, placing the fourth wire harness segment 64 above the water level and preventing continuous contact between the fourth wire harness segment 64 and water, thus avoiding potential danger. By placing some of the second wiring clips 32 on the front side wall of the water receiving tray 30, the fourth wire harness segment 64 can be routed downwards and pass through the front side wall of the water receiving tray 30, facilitating connection between the fourth wire harness and the electrical control box components.

[0066] According to some embodiments of the present invention, referring to Figure 7 and Figure 13The bottom wall of the water receiving tray 30 is provided with an overflow protrusion 34, and an overflow hole is provided on the overflow protrusion 34. The overflow hole penetrates the overflow protrusion 34 and the bottom wall of the water receiving tray 30 in a vertical direction. By providing an overflow protrusion 34 on the bottom wall of the water receiving tray 30 and an overflow hole on the overflow protrusion 34, water can be drained when the drain hole of the water receiving tray 30 is blocked, avoiding excessive water accumulation and overflow that could cause danger. The lowest position of the upper end face of the overflow protrusion 34 is the first height position 71, the height position of the upper end face of the wiring protrusion 33 is the second height position 72, the part of the front side wall of the water receiving tray 30 with the second wiring buckle 32 is the wiring side wall 35, and the height position of the upper end face of the wiring side wall 35 is the third height position 73. The first height position 71 is lower than the second height position 72, and the second height position 72 is lower than the third height position 73. By lowering the lowest position (first height position 71) of the upper end face of the overflow boss 34 to the second height position (second height position 72) of the upper end face of the wiring boss 33, the overflow hole can more stably and safely drain the water stored in the water collection tray 30, preventing excessive water accumulation in the water collection tray 30 from causing prolonged contact between the second wire harness segment 62 and water, which could lead to danger. The condensate adhering to the fourth wire harness segment 64 will concentrate at the lowest position on the fourth wire harness segment 64 under the influence of gravity and drip downwards. By lowering the second height position (72) of the upper end face of the wiring boss 33 to the third height position (73) of the upper end face of the wiring sidewall 35, the condensate on the fourth wire harness segment 64 can flow along the wire harness to the lower second height position (72) and eventually drip into the water collection tray, preventing water from the fourth wire harness segment 64 from dripping onto other components and causing danger.

[0067] According to some embodiments of the present invention, referring to Figure 7 and Figure 13 The height difference between the second height position 72 and the first height position 71 is x, and the value of x ranges from 4mm to 8mm. For example, the value of the height difference x between the second height position 72 and the first height position 71 can be 4mm, 5mm, 6mm, 7mm, 8mm, etc. By ensuring that the height difference x between the second height position 72 and the first height position 71 is not less than 4mm, the overflow hole can more fully and stably discharge the water stored in the water receiving tray 30; by ensuring that the height difference x between the second height position 72 and the first height position 71 is not greater than 8mm, the overall vertical dimension of the water receiving tray 30 can be prevented from becoming too large, which would increase the overall vertical dimension of the machine.

[0068] For example, the height difference between the second height position 72 and the first height position 71 is 6mm. By making the height difference between the second height position 72 and the first height position 71 6mm, the overflow hole can stably discharge the water stored in the water receiving tray 30, while the vertical dimension of the water receiving tray 30 can be appropriately reduced, which is beneficial to the miniaturization of the whole machine.

[0069] According to some embodiments of the present invention, referring to Figure 7 and Figure 13 The second cable clip 32 includes a clipping part 36, which is disposed opposite to the cable protrusion 33 in the vertical direction. The lower surface of the clipping part 36 is located at a fourth height position 74, which is higher than the second height position 72 and lower than the third height position 73. By making the fourth height position 74 higher than the second height position 72, a clipping hole 37 can be defined between the clipping part 36 and the cable protrusion 33, allowing the fourth cable harness to be accommodated in the clipping hole 37 and avoiding interference between the fourth cable harness and the clipping part 36. Since the lower surface of the clipping part 36 can limit the fourth cable harness upwards, by making the fourth height position 74 lower than the third height position 73, water on the fourth cable harness segment 64 can flow along the cable harness to a lower position under its own gravity and drip into the water receiving tray 30, preventing water on the fourth cable harness segment 64 from dripping onto other components and causing danger.

[0070] According to some embodiments of the present invention, referring to Figure 7 and Figure 13 The height difference between the fourth height position 74 and the second height position 72 is y, and the value of y ranges from 6mm to 10mm. For example, the value of the height difference y between the fourth height position 74 and the second height position 72 can be 6mm, 7mm, 8mm, 9mm, 10mm, etc. By ensuring that the height difference y between the fourth height position 74 and the second height position 72 is not less than 6mm, the space between the fastening part 36 and the wiring boss 33 is sufficient to accommodate the fourth wire harness, avoiding interference between the fastening part 36 and the fourth wire harness; by ensuring that the height difference y between the fourth height position 74 and the second height position 72 is not greater than 10mm, the fastening part 36 can more fully limit the positioning of the fourth wire harness.

[0071] For example, the height difference y between the fourth height position 74 and the second height position 72 can be 8mm. By making the height difference y between the fourth height position 74 and the second height position 72 8mm, the space between the latching part 36 and the wiring boss 33 can be sufficient to accommodate the fourth wire harness, avoiding interference between the latching part 36 and the fourth wire harness, and the latching part 36 can adequately limit the fourth wire harness.

[0072] According to some embodiments of the present invention, referring to Figure 7 and Figure 13The height difference between the third height position 73 and the fourth height position 74 is z, and the value of z ranges from 2mm to 6mm. For example, the height difference z between the third height position 73 and the fourth height position 74 can be 2mm, 3mm, 4mm, 5mm, 6mm, etc. By ensuring that the height difference z between the third height position 73 and the fourth height position 74 is not less than 2mm, the water on the fourth wire harness segment 64 can flow along the wire harness to a lower position under its own gravity and drip into the water receiving tray 30, thus more effectively preventing the water on the fourth wire harness segment 64 from dripping onto other parts and causing danger. By ensuring that the height difference z between the third height position 73 and the fourth height position 74 is not greater than 6mm, the overall vertical dimension of the water receiving tray 30 can be prevented from becoming too large, which would increase the overall vertical dimension of the machine.

[0073] For example, the height difference y between the third height position 73 and the fourth height position 74 can be 4mm. By making the height difference y between the third height position 73 and the fourth height position 74 4mm, it is possible to more effectively prevent water droplets on the fourth wiring harness from falling onto other components and causing danger, and it is also possible to avoid the overall vertical dimension of the water receiving tray 30 being too large, which would increase the overall vertical dimension of the machine.

[0074] According to some embodiments of this utility model, the air conditioner further includes a functional component, which is disposed within the housing assembly 10 and located in front of the air duct assembly 40. The functional component includes at least one of an air guiding unit and a display unit. The wiring harness connected to the functional component is a functional wiring harness, which runs along the middle of the air duct volute 41 in the left-right direction. For example, the functional component may include an air guiding unit, which may include a louver mechanism. The functional component controls the rotation of the louver mechanism to guide the airflow blown out by the air conditioner. The functional wiring harness is a low-voltage wiring harness. By running the functional wiring harness along the middle of the air duct volute 41 in the left-right direction, the distance between the functional wiring harness and the electric auxiliary heating wiring harness 60 can be increased, avoiding interference from the electric auxiliary heating wiring harness 60 to the functional wiring harness and reducing the risk of malfunction of the air conditioner's functional wiring harness.
