In some prior cabinet air conditioners, as shown in fig. 1 to 3, an air duct assembly for guiding an air flow is disposed between a front panel and a back panel 500. The air duct assembly comprises an air duct housing 100 consisting of a volute 110 and a volute tongue 120, a cross-flow fan 300 driven by a motor is arranged in the air duct housing 100, a first wire clamping groove 230 and a second wire clamping groove 260 for fixing cables are arranged on the back of the volute 110, and the first wire clamping groove 230 and the second wire clamping groove 260 are arranged side by side.

Example one

Fig. 4 is a schematic partial structural view of a cabinet air conditioner according to an embodiment of the present invention; FIG. 5 is an enlarged partial schematic view at C of FIG. 4; fig. 6 is a top view of fig. 4. As shown in fig. 4 to 6, the present embodiment provides an air conditioning duct assembly, wherein the duct housing 100 includes a volute 110 and a volute tongue 120, the volute tongue 120 is fixedly connected to the volute 110, and illustratively, the volute tongue 120 may be fixed to the volute 110 by means of bolt fastening or snap connection. The cross flow fan 300 is rotatably disposed on the volute 110, and when the cross flow fan 300 rotates, the air processed by the air conditioner heat exchanger can be driven to flow out from the air outlet of the air duct housing 100. It is easily understood that the side of the scroll casing 110 facing the cross flow fan 300 is the back of the scroll casing 110, the side of the scroll casing 110 facing away from the cross flow fan 300 is the back of the scroll casing 110, the cross flow fan 300 is driven by a motor, and cables for connecting the motor and an electrical box are routed from the back of the scroll casing 110.

The cable fixing part 200 is provided at a rear surface of the scroll casing 110 for arranging cables passing through an outer surface of the duct housing 100. It is easily understood that the number of the cable holders 200 is not limited and may be one or more, and when the number of the cable holders 200 is plural, the plural cable holders 200 are spaced apart in the vertical direction. In one possible implementation manner, the cable fixing portion 200 includes a first claw 210 and a first stopper 220, and illustratively, the first claw 210, the first stopper 220 and the volute 110 may be manufactured as a single piece through a one-step molding process. The free end of the first jaw 210 is bent backward, i.e., toward the backplate 500. Fig. 4 to 6 show that the first latch 210 is approximately in the shape of an "L-shaped structure", one end of the "L-shaped structure" is fixed to the outer surface of the duct housing 100, and the other end of the "L-shaped structure" extends in the horizontal direction and is bent backward.

With continued reference to fig. 4-6, the first retaining member 220 is spaced apart from the first pawl 210 in the horizontal direction and is opposite to the free end of the first pawl 210. The limiting member is approximately a "columnar structure", one end of the "columnar structure" is fixed to the outer surface of the air duct casing 100, and the other end of the "columnar structure" is suspended. The first latch 210 and the first stopper 220 define a first wire-clamping groove 230, and an opening of the first wire-clamping groove 230 is located on a side of the first wire-clamping groove 230 facing away from the volute 110. The volume of the first wire clamping groove 230 may be set according to actual needs, and this embodiment is not limited here. It is easy to understand that the space between the free end of the first latch 210 and the first stopper 220 is the opening of the first wire-clamping groove 230.

As can be understood by those skilled in the art, the first latch 210 and the first stopper 220 are disposed on the back surface of the volute 110, the first latch 210 and the first stopper 220 define a first wire-clamping groove 230, the first wire-clamping groove 230 is formed to be an annular structure provided with an opening, and the opening of the annular structure is located on a side of the annular structure facing away from the volute 110. During the process of fixing the cable, the worker may enter the inside of the first cable clamping groove 230 from the opening of the first cable clamping groove 230 in the direction indicated by the arrow in fig. 6. The opening of the first wire clamping groove 230 is not shielded by the evaporator 400 inside the air conditioner, and the operation space is large and cannot be interfered by the evaporator 400 inside the air conditioner when the cable is fixed, so that the efficiency of cable fixation can be improved.

Preferably, as shown in fig. 4-6, the opening of the first wire-clamping groove 230 is a flared opening with a large opening facing outward, that is, the opening width of the first wire-clamping groove 230 gradually decreases from the side away from the volute 110 to the side close to the volute 110. The opening wall surface of the first wire-clamping groove 230 may be an inclined plane or an arc surface, and the embodiment is not limited herein.

As can be understood by those skilled in the art, the opening of the first wire clamping groove 230 is set to be a bell mouth to play a role in guiding, and in the process that a cable enters the inside of the first wire clamping groove 230 from the opening of the first wire clamping groove 230, the opening of the first wire clamping groove 230 can rapidly guide the cable to the inside of the first wire clamping groove 230, so that the cable assembling efficiency is improved.

Specifically, as shown in fig. 5 to 6, a surface of the first stopper 220 facing the first jaw 210 includes a first vertical surface 221 connected to the scroll casing 110, and a first inclined surface 222 connected to the first vertical surface 221. Illustratively, the surface of the first limiting member 220 facing the first jaw 210 is provided with a bent segment extending in a vertical direction, and two opposite sides of the bent segment are a first vertical surface 221 and a first inclined surface 222, respectively. The included angle between the first vertical surface 221 and the first inclined surface 222 is not limited in the present embodiment, and can be set by those skilled in the art according to actual needs.

Accordingly, the first jaw 210 includes a first vertical section 211 connected to the scroll casing 110, a first horizontal section 222 connected to the first vertical section 211, and a first inclined section 223 connected to the first horizontal section 222, the first inclined section 223 extending toward the direction of the scroll casing 110. Illustratively, the first vertical section 211, the first horizontal section 222, and the first inclined section 223 are formed as one piece by a one-shot molding process. It should be noted that the first vertical section 211, the first horizontal section 222, and the first inclined section 223 are all disposed in the same horizontal plane. The length of each segment of the first jaw 210 and the size of the included angle between the first horizontal segment 222 and the first inclined segment 223 can be set by those skilled in the art according to actual needs.

It is easy to understand that the first inclined section 223 is opposite to the first inclined surface 222, and the surface of the first inclined section 223 facing the first limiting member 220 and the first inclined surface 222 together define the opening of the wire clamping groove.

As can be understood by those skilled in the art, both the surface of the first inclined section 223 facing the first limiting member 220 and the first inclined surface 222 function as a guiding surface, and during the process that the cable enters the inside of the first cable clamping groove 230 from the opening of the first cable clamping groove 230, the surface of the first inclined section 223 facing the first limiting member 220 and the first inclined surface 222 guide the cable to rapidly enter the inside of the first cable clamping groove 230, so as to improve the cable fixing efficiency.

As shown in fig. 4 to 6, the cable fixing portion 200 further includes a second claw 240 and a second stopper 250, the second claw 240 and the second stopper 250 are located in the same horizontal plane, and the volute 110, the second claw 240 and the second stopper 250 are exemplarily formed as a single piece through a one-step molding process. The second stopper 250 is disposed opposite to the free end of the second jaw 240 and defines a second catching groove 260 with the second jaw 240. It is easy to understand that the space between the free end of the second latch 240 and the second stopper 250 is the opening of the second wire-clamping groove 260.

Illustratively, the second jaw 240 and the first jaw 210 are arranged side by side in a horizontal direction or in a vertical direction, that is, the second jaw 240 and the first jaw 210 may be located in a same horizontal plane or the second jaw 240 and the first jaw 210 are staggered in a vertical direction, so that the second wire clamping groove 260 and the first wire clamping groove 230 may be located in a same horizontal plane or staggered in a vertical direction. It is worth mentioning that the first card wire slot 230 and the second card wire slot 260 are spaced apart.

As can be appreciated by those skilled in the art, one of the first and second wire-clamping grooves 230 and 260 may be used to fix a strong-current cable, and the other may be used to fix a weak-current cable. The strong electric cables include, but are not limited to, cables for connecting the fan motor and the electric box and electric heating wires inside the air conditioner; the weak current cable comprises but is not limited to a cable for connecting the swing blade motor and the electric box, and the strong current cable and the weak current cable are respectively fixed in two different wire clamping grooves, so that interference of strong current to weak current is avoided, and the reliability of signal transmission of the cable is ensured. The opening direction of the second wire clamping groove 260 is set to be the same as that of the first wire clamping groove 230, so that a worker can fix a cable inside the second wire clamping groove 260.

Preferably, the opening of the second wire-clamping groove 260 is also a flared opening with a large opening facing outwards, that is, the opening width of the second wire-clamping groove 260 gradually decreases from the side far away from the volute 110 to the side near the volute 110. Thereby facilitating entry of cables from the opening of the second card wire slot 260 into the interior of the second card wire slot 260.

Specifically, as shown in fig. 5 to 6, a surface of the second stopper 250 facing the second jaw 240 includes a second vertical surface 251 connected to the scroll casing 110, and a second inclined surface 252 connected to the second vertical surface 251. It is easy to understand that the surface of the second stopper 250 facing the second jaw 240 is also provided with a bent section extending in the vertical direction, and two opposite sides of the bent section are a second vertical surface 251 and a second inclined surface 252.

Likewise, the second jaw 240 includes a second vertical section 241 connected to the scroll casing 110, a second horizontal section 242 connected to the second vertical section 241, and a second inclined section 243 connected to the second horizontal section 242, the second inclined section 243 extending toward the scroll casing 110. The second vertical section 241, the second horizontal section 242 and the second inclined section 243 are located in the same horizontal plane. The second inclined section 243 is opposite to the second inclined surface 252, and the surface of the second inclined section 243 facing the second limiting member 250 and the second inclined surface 252 jointly define an opening of the second wire-clamping groove 260.

It is easy to understand that the surface of the second inclined section 243 facing the second limiting member 250 and the second inclined surface 252 also function as guide surfaces, and during the process that the cable enters the inside of the second wire clamping groove 260 from the opening of the second wire clamping groove 260, the surface of the second inclined section 243 facing the second limiting member 250 and the second inclined surface 252 guide the cable to rapidly enter the inside of the second wire clamping groove 260, so as to improve the efficiency of cable fixing.

It is worth mentioning that the minimum width of the opening of the first wire clamping groove 230 and the minimum width of the opening of the second wire clamping groove 260 are both smaller than the diameter of the cable. The opening is opened when pressure is applied to allow a cable to pass through the opening and enter the first wire clamping groove 230 or the second wire clamping groove 260, and the opening is restored to an original state after the pressure disappears so as to trap the cable in the first wire clamping groove 230 or the second wire clamping groove 260. Those skilled in the art can set the specific widths of the openings of the first card wire slot 230 and the second card wire slot 260 according to the diameter of the cable passing through the rear surface of the volute 110, and the embodiment is not limited. It is easy to understand that the cable can be effectively prevented from being pulled out from the first card wire slot 230 or the second card wire slot 260 by the above arrangement.

Further, taking the first jaw 210 as an example, a surface of the first inclined section 223 of the first jaw 210 opposite to the first limiting member 220 is an inclined surface, and the inclined surface may be set to be inclined upward, so that a bottom end of the inclined surface is closer to the first limiting member 220 than a top end of the inclined surface. Alternatively, it can also be said that the width of the top of the opening of the first wire clamping groove 230 is greater than the width of the bottom of the opening of the first wire clamping groove 230. The person skilled in the art can set the inclination angle of the inclined plane according to actual needs, and the embodiment is not limited. It is easy to think that the surface of the second inclined section 243 of the second jaw 240 opposite to the second limiting member 250 may also be provided with an upwardly inclined slope. The arrangement is convenient for fixing the cable, namely, the worker only needs to press the cable from top to bottom at the opening of the first wire clamping groove 230 and the second wire clamping groove 260, so that pressure can be applied to the opening to open the opening, and then the cable penetrates through the opening to enter the first wire clamping groove 230 or the second wire clamping groove 260.

In a possible implementation manner, the first jaw 210 and the second jaw 240 are a single piece, and free ends of the two jaws are bent in opposite directions, specifically, the free end of the first jaw 210 is bent backward, and the free end of the second jaw 240 is bent forward. Along the flowing direction of the air inside the air duct housing 100, the first latch 210 and the second latch 240 are located between the first stopper 220 and the second stopper 250. The first jaw 210 and the second jaw 240 use the same fixed end, or alternatively, two jaws form a "T-shaped structure" shown in fig. 5-6, and the bottom end of the "T-shaped structure" is fixed to the scroll casing 110. It is easy to understand that the first jaw 210 and the second jaw 240 are made into a single piece, so that the horizontal distance between the first wire clamping groove 230 and the second wire clamping groove 260 can be reduced, and the worker can conveniently fix the cable.

One skilled in the art can also separate the first jaw 210 from the second jaw 240 to ensure that the strong and weak cables do not interfere with each other. Several arrangements of the first and second jaws 210 and 240 are described below, but it should be understood by those skilled in the art that the following specific implementation should not be considered as a specific limitation to the first and second jaws 210 and 240.

Fig. 7 is a schematic structural diagram of another arrangement of the first and second jaws, and as shown in fig. 7, in one possible implementation, the first and second jaws 210 and 240 are spaced apart in a horizontal direction, and a bending direction of a free end of the second jaw 240 is opposite to a bending direction of a free end of the first jaw 210. Those skilled in the art can also set the bending direction of the free end of the second latch 240 to be the same as the bending direction of the free end of the first latch 210, and the embodiment is not limited herein.

Fig. 8 is a schematic structural diagram of another arrangement of the first and second jaws, and as shown in fig. 8, in another possible implementation, the first and second jaws 210 and 240 are arranged on the same vertical line and a space is provided between the first and second jaws 210 and 240 in a vertical direction.
