Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to an air conditioner cabinet and an air conditioner. Background Art

[0002] At present, some air-conditioning cabinets are equipped with electric heaters to meet the purpose of delivering hot air to the room. The electric heaters are usually set upstream of the air duct assembly, and the air flow is converted into hot air by heat exchange with the electric heater when passing through, and then further delivered to the room.

[0003] However, the electric heater in the existing air-conditioning cabinet is usually installed and fixed on the evaporator upper bracket / evaporator lower bracket. In the air-conditioning cabinet, in addition to the electric heater, the main power cable is the cable connected to the fan motor. However, the above installation method causes the two power cables to be far apart, making the wiring operation of the electric heater lead and the wiring operation of the fan motor lead two independent processes. The electric heater and the wind drive motor need to be wired separately and then connected to the electrical control box, which has low operating efficiency. Utility Model Content

[0004] A first aspect of the present invention aims to provide an air-conditioning cabinet unit to solve the technical problem of low efficiency in managing the wires of existing electric heaters.

[0005] The first aspect of the present invention provides an air conditioning cabinet, comprising:

[0006] An air duct assembly and an air duct support, wherein the air duct assembly has an air duct wall, and an axial flow fan is arranged in the air duct wall;

[0007] The air duct wall is mounted on the air duct support, and the air inlet of the air duct wall is located at the rear side of the air duct support; an electric heater is provided at the rear side of the air duct support, and the electric heater is located at the upstream side of the air inlet;

[0008] The electric heater is connected to a heater lead, and the heater lead extends from the rear side of the air duct support to the front side of the air duct support and is connected to the electric control box.

[0009] The beneficial effects brought by the utility model air conditioning cabinet are:

[0010] By extending the heater lead of the electric heater arranged on the upstream side of the air inlet of the duct wall from the rear side of the duct support to the front side of the duct support, it can be connected to the electrical control box from the front side of the duct support together with the remaining leads of the air-conditioning cabinet. In this way, the heater lead of the electric heater and the remaining leads of the air-conditioning cabinet are managed together, and the wiring operation can be completed only once, which improves operational efficiency and reduces production costs.

[0011] In an optional technical solution, the air duct support member is provided with a first wire pressing member and / or a lead portion, and the heater lead is connected to the first wire pressing member and / or the lead portion.

[0012] By setting a lead part or a first wire pressing part, the heater lead can pass through the lead part or be pressed by the first wire pressing part, thereby preventing the heater lead from being affected by airflow or vibration and causing large shaking, resulting in damage to the heater lead or loose connection, thereby improving the reliability and service life of the air-conditioning cabinet.

[0013] In an optional technical solution, the lead portion includes a lead groove with two ends open, and the lead groove is located on the side wall of the air duct support member and extends along the front-to-back direction of the air duct support member.

[0014] By setting a lead groove with open ends on the side wall of the duct support, not only the bending degree of the heater lead is reduced, which is beneficial to improving the service life of the heater lead, but the lead groove can also be used to limit the relative position of the heater lead with respect to the duct support in the up and down directions, and the length of the area that plays a limiting role can be increased, thereby improving the fixation reliability of the heater lead.

[0015] In an optional technical solution, the wire guide groove includes a groove bottom plate, and a notch portion is provided at the front end of the groove bottom plate.

[0016] By providing a notch at the front end of the bottom plate of the lead trough, the heater lead can be routed through the notch toward the left-right center of the duct support, where it can merge with other leads and pass to the electrical control box. The notch allows for vertical positioning of the heater lead from the lead trough to the left-right center of the duct support, reducing the length of the free-hanging section of the heater lead and improving its securement.

[0017] In an optional technical solution, the wire guide groove includes a wire pressing baffle, which is arranged at the groove opening of the wire guide groove. The wire guide groove includes a first groove wall and a second groove wall fixed on opposite sides of the groove bottom plate. The wire pressing baffle is arranged on the first groove wall and protrudes from the first groove wall in the direction of the second groove wall.

[0018] By setting a wire pressing baffle and making it protrude toward the other groove wall of the lead groove, the heater lead can be blocked after passing through or buried in the lead groove to prevent the heater lead from popping out of the lead groove, thereby improving the reliability of fixation.

[0019] In an optional technical solution, the second groove wall is also provided with a protrusion, which protrudes from the second groove wall in the direction of the first groove wall; the protrusion is located between the front end of the guide groove and the wire pressing baffle; the side of the protrusion facing away from the groove bottom plate is provided with a first rib, and the first rib is connected to the second groove wall.

[0020] By providing a raised portion projecting in the opposite direction from the wire-pressing baffle, the raised portion and the wire-pressing baffle can be used to jointly clamp the heater lead, improving the securing effect. Placing the raised portion before the wire-pressing baffle allows the heater lead to bend horizontally within the lead slot as it passes around the raised portion, forming a bend with the raised portion facing the notch. This allows the heater lead to pass smoothly through the notch, avoiding bending directly toward the notch, which would result in a narrow bending radius and damage to the heater lead during use. The first rib further assists the heater lead in forming this bend.

[0021] In an optional technical solution, the first wire pressing member is fixedly arranged on the rear side of the air duct support member and has a first wire accommodating groove and a first guiding portion;

[0022] The first wire accommodating groove is recessed in a direction away from the air duct support member, one end of the first wire accommodating groove extends to the air duct support member, and a first wire passing gap is formed between the other end and the rear surface of the air duct support member, and the width of the first wire passing gap is smaller than the diameter of the heater lead;

[0023] The first guide portion extends from the first wire-passing gap in a direction away from the air duct support member and the wire-containing groove.

[0024] Since there is an incoming air flow behind the air duct support, a first wire pressing member is provided on the rear side of the air duct support, which can fix the heater lead between the electric heater and the lead groove, thereby reducing the swing of this part of the heater lead caused by the influence of wind. By providing a first wire accommodating groove to accommodate the heater lead, and the width of the first wire passing gap is smaller than the diameter of the heater lead, the heater lead can be prevented from escaping from the first wire accommodating groove. The first guide portion is provided to extend from the first wire passing gap in a direction away from the air duct support and the wire accommodating groove at the same time. When the heater lead needs to be removed from the first wire pressing member, the first guide portion can be pulled backward to increase the width of the first wire passing gap so that the heater lead can pass through the first wire passing gap.

[0025] In an optional technical solution, the air duct support member is equipped with the support grille, the axial flow fan is installed in the middle of the support grille, the support grille includes wire-passing grille bars, and the wire-passing grille bars are passed through by motor leads; the motor leads are configured to electrically connect the electric control box and the axial flow fan;

[0026] A second wire pressing member is fixedly provided on the front side of the air duct support member, and the second wire pressing member has a second wire accommodating groove and a second guide portion;

[0027] The second wire accommodating groove is recessed in a direction away from the air duct support and is used to accommodate the motor lead; one end of the second wire accommodating groove extends to the air duct support, and a second wire passing gap is defined between the other end and the rear surface of the air duct support, wherein the width of the second wire passing gap is smaller than the diameter of the motor lead;

[0028] The second guide portion extends from the second wire-passing gap in a direction away from the air duct support member and the second wire-containing groove.

[0029] A second wire pressing member is fixedly provided on the front side of the air duct support member, and the motor lead can be fixed after the motor lead is led out of the wire grid bar, thereby reducing the swing of the motor lead in this part. By providing a second wire accommodating groove to accommodate the motor lead, and the width of the second wire passing gap is smaller than the diameter of the motor lead, the motor lead can be prevented from escaping from the second wire accommodating groove. A second guide portion is provided to extend from the second wire passing gap in a direction away from the air duct support member and the second wire accommodating groove at the same time. When the motor lead needs to be taken out of the second wire pressing member, the second guide portion can be pulled forward to increase the width of the second wire passing gap so that the motor lead can pass through the second wire passing gap.

[0030] In an optional technical solution, a third wire pressing member is further fixedly provided on the front side surface of the air duct support member, the third wire pressing member is lower than the second wire pressing member, the third wire pressing member has a third wire accommodating groove and a third guide portion, the third wire accommodating groove is recessed in a direction away from the air duct support member and is used to accommodate the heater lead and the motor lead; one end of the third wire accommodating groove extends to the air duct support member, and a third wire passing gap is defined between the other end and the rear surface of the air duct support member, and the width of the third wire passing gap is smaller than the diameter of at least one of the motor lead and the heater lead;

[0031] The third guide portion extends from the third wire-passing gap in a direction away from the air duct support member and the third wire-accommodating groove.

[0032] A third wire pressing member is fixedly provided on the front side surface of the air duct support member, and the heater lead and the motor lead can be fixed together after the motor lead is led out of the wire grid bar and after the heater lead passes through the lead groove, thereby reducing the swing of the heater lead and the motor lead. By providing a third wire accommodating groove to accommodate the heater lead and the motor lead, and the width of the third wire passing gap is smaller than the diameter of at least one of the heater lead and the motor lead, the heater lead and the motor lead can be prevented from escaping from the third wire accommodating groove. A third guide portion is provided to extend from the third wire passing gap in a direction away from the air duct support member and the third wire accommodating groove at the same time. When it is necessary to remove the heater lead and the motor lead from the third wire pressing member, the third guide portion can be pulled forward to increase the width of the third wire passing gap, so that the heater lead and the motor lead can pass through the third wire passing gap.

[0033] A second aspect of the present invention is to provide an air conditioner to solve the technical problem of low efficiency in managing the leads of an electric heater.

DETAILED DESCRIPTION

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

The bottom refers to the side of the air-conditioning cabinet facing the ground. The top refers to the side of the air-conditioning cabinet facing the roof. Left and right can be defined based on the above-mentioned front, back and bottom, that is, when the observer faces the wall on which the air-conditioning cabinet is installed, the observer's left hand direction is the left side, and the observer's right hand direction is the right side. In addition, the inside and outside are defined based on components in the shape of a cavity, box or cylinder. The side of the cavity, box or cylinder facing its internal space is the inside, and the outside is the side of the cavity or box facing its external space.

[0048] Example 1:

[0049] Figure 1 A schematic diagram of the internal structure of an air-conditioning cabinet provided in Example 1 of the present utility model; Figure 2 The figure is a schematic diagram of the internal structure of the air-conditioning cabinet provided by the first embodiment of the present invention as viewed from another direction; The figure is a schematic diagram of the internal structure of the air-conditioning cabinet provided by the first embodiment of the present invention as viewed from yet another direction. Figure 1-Figure 3As shown, the air-conditioning cabinet provided in the first embodiment of the present invention includes a duct assembly 100 and a duct support 500. The duct assembly 100 has a duct wall 110, and an axial fan 200 is provided in the duct wall 110; the duct wall 110 is installed on the duct support 500, and the air inlet of the duct wall 110 is located on the rear side of the duct support 500; the rear side of the duct support 500 is provided with an electric heater 310, and the electric heater 310 is located on the upstream side of the air inlet; the electric heater 310 is connected to a heater lead 320, and the heater lead 320 extends from the rear side of the duct support 500 to the front side of the duct support 500 and is connected to the electric control box 400.

[0050] By extending the heater lead 320 of the electric heater 310 arranged on the upstream side of the air inlet of the duct wall 110 from the rear side of the duct support 500 to the front side of the duct support 500, it can be connected to the electrical control box 400 from the front side of the duct support 500 together with the remaining leads of the air-conditioning cabinet. In this way, the heater lead 320 of the electric heater 310 and the remaining leads of the air-conditioning cabinet are managed together, and the wiring operation can be completed only once, which improves operating efficiency and reduces production costs.

[0051] Specifically, in this embodiment, the axial direction of the duct assembly 100 is the front-to-back direction. The rear wall of the air conditioner (not shown) is provided with an air inlet, and the indoor heat exchanger (not shown) of the air conditioner is positioned between the air inlet and the air inlet of the duct wall 110. The electric heater 310 is positioned between the indoor heat exchanger and the air inlet of the duct wall 110. That is, along the air inlet direction of the air conditioner, the air inlet, indoor heat exchanger, electric heater 310, and air inlet can be positioned sequentially. When the air conditioner is in heating mode, after absorbing heat from the indoor heat exchanger, the air can also absorb heat from the electric heater 310, further increasing the air outlet temperature. Furthermore, since the indoor heat exchanger may produce condensation in cooling mode, a water collection pan 510 is typically provided below the heater to collect the condensation. Extending the heater lead 320 to the front side of the duct support member 500 and connecting it to the electrical control box 400 can reduce interference between the heater lead 320 and the water collection pan 510.

[0052] Specifically, the electric heater 310 is vertically positioned behind the duct support 500. If the air conditioner cabinet has multiple duct assemblies 100, it is positioned corresponding to the air inlets of the duct assemblies 100. The heater lead 320 of the electric heater 310 can be extended from the bottom of the electric heater 310 and connected to the electrical control box 400. This shortens the overall length of the heater lead 320, reducing the material cost of the air conditioner cabinet. It also avoids the need to extend the heater lead 320 from the top of the electric heater 310, which would require additional locations to secure the heater lead 320 and increase production costs due to the increased number of steps involved.

[0053] like Figure 1-Figure 3 As shown, optionally, the air duct support 500 is provided with a first wire pressing member 540 and / or a lead portion, and the heater lead 320 is connected to the first wire pressing member 540 and / or the lead portion.

[0054] By setting a lead part or a first wire pressing piece 540, the heater lead 320 can pass through the lead part or be pressed by the first wire pressing piece 540, thereby preventing the heater lead 320 from being affected by airflow or vibration and causing large shaking, resulting in damage to the heater lead 320 or loose connection, thereby improving the reliability and service life of the air-conditioning cabinet.

[0055] The lead portion may be a lead groove 530 provided on the air duct support 500 or a hole passing through in the front-to-back direction.

[0056] like Figure 1-Figure 3 As shown, optionally, the lead portion includes a lead groove 530 with two ends open, and the lead groove 530 is located on the side wall of the air duct support member 500 and extends along the front-to-back direction of the air duct support member 500.

[0057] By setting a lead groove 530 with both ends open on the side wall of the air duct support 500, not only the bending degree of the heater lead 320 is reduced, which is beneficial to improving the service life of the heater lead 320, but also the lead groove 530 can be used to limit the relative position of the heater lead 320 with respect to the air duct support 500 in the up and down directions, and the length of the area that plays a limiting role can be increased, thereby improving the fixing reliability of the heater lead 320.

[0058] Specifically, in this embodiment, the duct support member 500 primarily supports the duct assembly 100 via a support plate 521. Edge ribs 522 are provided on the left and right edges of the support plate 521 to reinforce the support plate 521. The wire guide groove 530 is provided on the edge ribs 522. The rear end of the wire guide groove 530 protrudes rearward from the support plate 521, while the front end of the wire guide groove 530 protrudes forward from the support plate 521.

[0059] Specifically, in this embodiment, the lead groove 530 is arranged on the left side wall of the air duct support 500. The main reason is that the motor lead 211 of the fan motor 210 described later is led out from the lower left part of the support grille 120 described later. The lead groove 530 is arranged here so that the heater lead 320 can pass through the lead groove 530 and only needs a shorter distance to merge with the motor lead 211 of the fan motor 210, which is convenient for the operator to organize the wires.

[0060] like Figure 1-Figure 3 As shown, optionally, the lead groove 530 includes a groove bottom plate 531 , and a notch portion 5311 is provided at the front end of the groove bottom plate 531 .

[0061] By providing a notch 5311 at the front end of the bottom plate 531 of the lead trough 530, the heater lead 320 can be routed through the notch 5311 toward the middle of the duct support 500 in the left-right direction, where it can merge with other leads and pass to the electrical control box 400. The provision of the notch 5311 allows the heater lead 320 to be positioned vertically in the area between the lead trough 530 and the middle of the duct support 500 in the left-right direction, thereby reducing the length of the freely suspended section of the heater lead 320 and improving the securing effect of the heater lead 320.

[0062] It should be noted that the groove bottom plate 531 is defined based on the groove properties fixed to the lead groove 530 itself, and does not mean that the groove bottom plate 531 is located at the bottom of the groove in actual space. Specifically, in this embodiment, the lead groove 530 is arranged on the left side wall of the air duct support 500, and the notch of the lead groove 530 is on the left side, and the groove bottom plate 531 is located on the right side of the lead groove 530. The heater lead 320 can turn right in the lead groove 530 and pass through the notch portion 5311. Compared with the solution in which the heater lead 320 passes through the lead groove 530, extends forward, and then turns toward the middle of the left and right directions of the air duct support 500, the upper and lower positions of this section extending roughly in the left and right directions can be more effectively controlled, and the length of the freely suspended section can also be reduced.

[0063] like Figure 1-Figure 3 As shown, optionally, the lead groove 530 includes a wire pressing baffle 534, which is arranged at the groove opening of the lead groove 530. The lead groove 530 includes a first groove wall 532 and a second groove wall 533 fixed on opposite sides of the groove bottom plate 531. The wire pressing baffle 534 is arranged on the first groove wall 532 and protrudes from the first groove wall 532 toward the direction of the second groove wall 533.

[0064] By setting a wire pressing baffle 534 and making it protrude toward the other side wall of the lead groove 530, the heater lead 320 can be blocked after passing through or being buried in the lead groove 530 to prevent the heater lead 320 from popping out of the lead groove 530, thereby improving the reliability of the fixation.

[0065] Specifically, in this embodiment, the wire pressing baffle 534 can be only provided on one side wall of the wire guide groove 530 , such as the lower side wall of the wire guide groove 530 , that is, the wire pressing baffle 534 extends upward from the lower side wall of the wire guide groove 530 .

[0066] like Figure 1-Figure 3As shown, optionally, the second groove wall 533 is further provided with a protrusion 535, which protrudes from the second groove wall 533 in the direction of the first groove wall 532; in the extension direction of the lead groove 530, the protrusion 535 is located between the front end of the lead groove 530 and the wire pressing baffle 534; a side of the protrusion 535 facing away from the groove bottom plate 531 is provided with a first rib 5351, and the first rib 5351 is connected to the second groove wall 533.

[0067] By providing a raised portion 535 that projects in the opposite direction to the wire pressing baffle 534, the raised portion 535 and the wire pressing baffle 534 can be used to clamp the heater lead 320 together, improving the fixing effect. Placing the raised portion 535 before the wire pressing baffle 534 allows the heater lead 320 to bend horizontally in the lead slot 530 when bypassing the raised portion 535, forming a bend with the raised direction toward the notch, so that the heater lead 320 can smoothly pass through the notch 5311, avoiding bending directly toward the notch 5311, which would result in the heater lead 320 having an excessively small bending radius and causing damage to the heater lead 320 during use. The first rib 5351 can further assist the heater lead 320 in forming the aforementioned bend.

[0068] Specifically, the protrusion 535 is located in front of the wire pressing baffle 534. The wire pressing baffle 534 protrudes upward from the first groove wall 532 below the notch of the wire guide groove 530, while the protrusion 535 protrudes downward from the second groove wall 533 above the notch of the wire guide groove 530. In this embodiment, the protrusion 535 is located on the side of the groove bottom plate 531 of the wire guide groove 530. In other words, it can also be considered that the protrusion 535 protrudes from the groove bottom plate 531 of the wire guide groove 530 toward the notch. The first rib 5351 of the protrusion 535 is located on the side of the protrusion 535 facing the notch. The position where the first rib 5351 is connected to the lower end of the protrusion 535 is a triangle with a smaller bottom and a larger top, and the wire pressing baffle 534 is also provided with a second rib 5341 to connect the side of the wire pressing baffle 534 facing the groove bottom plate 531 and the second groove wall 533, and the position where the second rib 5341 is connected to the top of the wire pressing baffle 534 is a triangle with a smaller top and a larger bottom. The first rib 5351 and the second rib 5341 cooperate with each other, so that the heater lead 320 can form a bend that first bulges upward and then bulges downward when it bypasses the first rib 5351 and the second rib 5341 when it is routed in the lead groove 530, and can also improve the fixing ability of the lead groove 530 to the heater lead 320.

[0069] like Figure 1-Figure 3 As shown, optionally, the first wire pressing member 540 is fixedly arranged on the rear side of the air duct support member 500 and has a first wire accommodating groove 541 and a first guide portion 542;

[0070] The first wire accommodating groove 541 is recessed in a direction away from the air duct support member 500. One end of the first wire accommodating groove 541 extends to the air duct support member 500, and a first wire passing gap 543 is defined between the other end and the rear surface of the air duct support member 500. The width of the first wire passing gap 543 is smaller than the diameter of the heater lead 320.

[0071] The first guide portion 542 extends from the first wire-passing gap 543 in a direction away from the air duct support member 500 and the first wire-accommodating groove 541 .

[0072] Since there is an incoming air flow behind the duct support member 500, a first wire pressing member 540 is provided on the rear side of the duct support member 500 to fix the heater lead 320 between the electric heater 310 and the lead groove 530, thereby reducing the swinging of the heater lead 320 caused by the wind. By providing a first wire accommodating groove 541 to accommodate the heater lead 320, and the width of the first wire passing gap 543 is smaller than the diameter of the heater lead 320, the heater lead 320 can be prevented from escaping from the first wire accommodating groove 541. A first guide portion 542 is provided to extend from the first wire passing gap 543 in a direction away from the duct support member 500 and the first wire accommodating groove 541. When it is necessary to remove the heater lead 320 from the first wire pressing member 540, the first guide portion 542 can be pulled backward to increase the width of the first wire passing gap 543, so that the heater lead 320 can pass through the first wire passing gap 543.

[0073] The first wire pressing member 540 can be integrally formed with the air duct support member 500, and the first wire pressing member 540 includes a first plate body bent along its thickness direction and two parallel first side ribs. The first side ribs are generally arc-shaped, and the first plate body can form a first wire accommodating groove 541 and a first guide portion 542. In addition, when the heater lead 320 is fixed to the first wire pressing member 540, the heater lead 320 can be moved from the first guide portion 542 to the first wire accommodating groove 541. Since the first guide portion 542 extends away from the first wire accommodating groove 541 and away from the air duct support member 500, the heater lead 320 can be used to squeeze the first guide portion 542 backward to allow the heater lead 320 to pass through the first wire-passing gap 543.

[0074] like Figure 2 and Figure 3 As shown, optionally, the air duct support member 500 is installed with a support grille 120, and the fan motor 210 is installed in the middle of the support grille 120. The support grille 120 includes a wire grid bar 121, and the wire grid bar 121 is passed through a motor lead 211; the motor lead 211 is configured to electrically connect the electric control box 400 and the axial flow fan 200;

[0075] A second wire pressing member 550 is fixedly provided on the front side of the duct support member 500. The second wire pressing member 550 has a second wire accommodating groove 551 and a second guide portion 552. The second wire accommodating groove 551 is recessed away from the duct support member 500 and is used to accommodate the motor lead 211. One end of the second wire accommodating groove 551 extends to the duct support member 500, and a second wire passing gap 553 is defined between the other end and the rear surface of the duct support member 500. The width of the second wire passing gap 553 is smaller than the diameter of the motor lead 211.

[0076] The second guide portion 552 extends from the second wire-passing gap 553 in a direction away from the air duct support member 500 and the second wire-accommodating groove 551 .

[0077] A second wire pressing member 550 is fixedly provided on the front side of the air duct support member 500, and the motor lead 211 can be fixed after the motor lead 211 is led out of the wire grid bar 121, thereby reducing the swing of the motor lead 211 in this part. By providing a second wire accommodating groove 551 to accommodate the motor lead 211, and the width of the second wire gap 5533 is smaller than the diameter of the motor lead 211, the motor lead 211 can be prevented from escaping from the second wire accommodating groove 551. A second guide portion 552 is provided to extend from the second wire gap 553 to the direction away from the air duct support member 500 and the second wire accommodating groove 551 at the same time. When the motor lead 211 needs to be removed from the second wire pressing member 550, the second guide portion 552 can be pulled forward to increase the width of the second wire gap 5533 so that the motor lead 211 can pass through the second wire gap 5533.

[0078] The axial flow fan 200 includes a fan motor 210 and an axial flow fan 220 driven by the fan motor 210. The fan motor 210 is connected to the electric control box 400 via a motor lead 211.

[0079] Wherein, two air duct assemblies 100 are provided in the present embodiment, and the two air duct assemblies 100 are arranged in the up-down direction. Naturally, an axial flow fan 200 is provided in each air duct assembly 100, so the two fan motors 210 are also arranged in the up-down direction. At the lower left of each support grid 120, a second wire pressing member 550 is provided on the front surface of the air duct support member 500. The second wire pressing member 550 can be opened toward the left side. The second wire pressing member 550 can be integrally formed with the air duct support member 500, and the second wire pressing member 550 includes a second plate body bent along its own thickness direction and two second side ribs arranged in parallel, the second side ribs being roughly arc-shaped, and the second plate body can form a second wire accommodating groove 551 and a second guide portion 552. In addition, when the motor lead 211 is fixed to the second wire pressing piece 550, the motor lead 211 can be moved from the second guide portion 552 to the second wire accommodating groove 551. Since the second guide portion 552 extends away from the second wire accommodating groove 551 and away from the air duct support 500, the motor lead 211 can be used to squeeze the second guide portion 552 forward so that the motor lead 211 passes through the second wire passing gap 5533.

[0080] like Figure 2 and Figure 3 As shown, optionally, a third wire pressing member 560 is further fixed to the front side of the duct support member 500. The third wire pressing member 560 is lower than the second wire pressing member 550. The third wire pressing member 560 has a third wire accommodating groove 561 and a third guide portion 562. The third wire accommodating groove 561 is used to accommodate the heater lead 320 and the motor lead 211; one end of the third wire accommodating groove 561 extends to the duct support member 500, and a third wire passing gap 563 is defined between the other end and the rear surface of the duct support member 500. The width of the third wire passing gap 563 is smaller than the diameter of at least one of the motor lead 211 and the heater lead 320;

[0081] The third guide portion 562 extends from the third wire-passing gap 563 in a direction away from the air duct support member 500 and the third wire-accommodating groove 561 .

[0082] A third wire-holding member 560 is provided on the front side of the air duct support member 500. This secures the heater lead 320 and the motor lead 211 together after the motor lead 211 exits the wire grid bar 121 and after the heater lead 320 passes through the wire groove 530, thereby reducing swinging of the heater lead 320 and the motor lead 211. By providing the third wire-holding groove 561 to accommodate the heater lead 320 and the motor lead 211, and by ensuring that the width of the third wire-holding gap 563 is smaller than the diameter of at least one of the heater lead 320 and the motor lead 211, the heater lead 320 and the motor lead 211 are prevented from escaping from the third wire-holding groove 561. A third guide portion 562 is provided to extend from the third wire gap 563 in a direction away from the air duct support 500 and the third wire accommodating groove 561. When it is necessary to remove the heater lead 320 and the motor lead 211 from the third wire pressing member 560, the third guide portion 562 can be pushed forward to increase the width of the third wire gap 563 so that the heater lead 320 and the motor lead 211 can pass through the third wire gap 563.

[0083] Among them, the third wire pressing member 560 can be integrally formed with the air duct support member 500, and the third wire pressing member 560 includes a third plate body bent along its own thickness direction and two third side ribs arranged in parallel, the third side ribs are roughly arc-shaped, and the third plate body can form a third wire accommodating groove 561 and a third guide portion 562. In addition, when the motor lead 211 is fixed to the third wire pressing member 560, the heater lead 320 and the motor lead 211 can be moved from the third guide portion 562 to the third wire accommodating groove 561. Since the third guide portion 562 extends in a direction away from the third wire accommodating groove 561 and away from the air duct support member 500, the heater lead 320 and the motor lead 211 can be used to squeeze the third guide portion 562 forward, so that the heater lead 320 and the motor lead 211 pass through the third wire gap 563.

[0084] Specifically, the third wire pressing member 560 is provided at the front edge of the bottom plate 523 of the air duct support member 500, and the front edge of the bottom plate 523 also belongs to the front surface of the air duct support member 500. Furthermore, a recessed portion can be provided at the front edge of the bottom plate 523, and the heater lead 320 and the motor lead 211 are jointly accommodated between the recessed portion and the third wire pressing member 560.

[0085] In this embodiment, the heater's power is greater than that of the blower motor 210, so the diameter of the heater lead 320 is also greater than the diameter of the motor lead 211. Therefore, within the third wire-receiving slot 561, the heater lead 320 is positioned between the motor lead 211 and the third wire-receiving gap 563. Similarly, if the motor lead 211 has a larger diameter than the heater lead 320, the motor lead 211 is positioned between the heater lead 320 and the third wire-receiving gap 563. That is, the heater lead 320 and the motor lead 211, with the larger diameter, are positioned between the smaller diameter and the third wire-receiving gap 563. Thus, the third wire-receiving gap 563 traps the larger diameter within the third wire-receiving slot 561 while also preventing the smaller diameter from escaping.
