The technical solution of the present disclosure is described below with reference to the accompanying drawings and specific embodiments.

An air conditioner according to some embodiments of the present disclosure is intended to at least to some extent solve the technical problem that a wire group on one side of a heat exchanger of the air conditioner needs to be connected to an electrical control box, and one version needs to be routed inside the air conditioner shell, but the internal space of the shell is small, thus causing inconvenience in assembly and subsequent maintenance of the air conditioner.

FIG. 1 is a schematic diagram of the structure of an air conditioner according to some embodiments of the present disclosure; FIG. 2 is a schematic diagram of the arrangement of the wire group of the air conditioner in FIG. 1; and FIG. 4 is a schematic diagram of the arrangement of the radiator of the air conditioner in FIG. 1. In combination with FIG. 1, FIG. 2 and FIG. 4, the air conditioner according to some embodiments of the present disclosure includes: a housing 40, an electric control assembly 60 and a wire group 70. A heat exchanger 50, a crossbeam 100 and a fan 90 are arranged in the housing 40. The crossbeam 100 is arranged between the heat exchanger 50 and the fan 90, and a notch 1001 is opened on the crossbeam 100. The electric control assembly 60 includes an electric control box 601 arranged in the housing 40 and connected to the crossbeam 100, and a control component 602 arranged in the electric control box 601. The end of the electric control box 601 facing the crossbeam 100 is opened with an opening 6011 connected to the notch 1001. One end of the wire group 70 is connected to the heat exchanger 50, and the other end is successively passed through the notch 1001 and the opening 6011 to connect with the control component 602.

The air conditioner may be a ducted air conditioner.

The crossbeam 100 can close the opening 6011, so that an end plate does not need to be provided at the end of the electric control box 601 facing the crossbeam 100. The crossbeam 100 can be used as the end plate of the electric control box 601, thereby improving the utilization rate of components and reducing costs.

The control component 602 can be a PCB (Printed Circuit Board).

In the related art, the wiring method of the indoor unit of the duct air conditioner is as follows: the wire group on one side of the heat exchanger is generally routed from the inside of the shell and then connected to the electrical control box. In this way, the wire group needs to pass through the crossbeam into the area of the shell that supports the fan, and then pass through the electrical control box to connect with the control components. Therefore, it is necessary to thread the wires in the narrow space in the shell. However, the internal space of the shell is small, which will lead to inconvenience in assembly and maintenance of the air conditioner.

In the technical solutions according to some embodiments of the present disclosure, since the heat exchanger 50, the crossbeam 100 and the fan 90 are arranged in the housing 40 of the air conditioner, the crossbeam 100 is arranged between the heat exchanger 50 and the fan 90, and a notch 1001 is provided on the crossbeam 100, the crossbeam 100 is supported by the housing 40. Since the electric control assembly 60 includes an electric control box 601 arranged in the housing 40 and connected to the crossbeam 100 and a control component 602 arranged in the electric control box 601, and the electric control box 601 is provided with an opening 6011 communicating with the notch 1001 at the end facing the crossbeam 100, the electric control box 601 is supported by the housing 40, and the electric control box 601 is supported by the housing 40. Support control component 602. Since one end of wire group 70 is connected to heat exchanger 50, and the other end is sequentially passed through notch 1001 and opening 6011 to connect to control component 602, it is not necessary to pass wire group 70 through crossbeam 100 and then enter the area of housing 40 carrying fan 90, that is, it is not necessary to thread wire in the narrow space of housing 40, so the operation space is large, assembly and maintenance are convenient, and efficiency is high.

FIG. 7 is a schematic diagram of the seal and the crossbeam of the air conditioner in FIG. 1 ; FIG. 8 is a schematic diagram of the structure of the seal in FIG. 7 ; FIG. 9 is a front view of the seal in FIG. 7 ; and FIG. 10 is a rear view of the seal in FIG. 7 . In combination with FIG. 7 , FIG. 8 , FIG. 9 and FIG. 10 , in some embodiments, in order to prevent condensed water from entering the electric control box 601 , the air conditioner may further include: a seal 120 . The seal 120 is connected to the crossbeam 100 and is arranged in the notch 1001 . The wire group 70 is sequentially arranged through the seal 120 and the electric control box 601 and connected to the control component 602 . The notch 1001 is sealed by the seal 120 to prevent condensed water from entering the electric control box 601 through the notch 1001 , thereby ensuring the safety of the control component 602 .

2 and 7 , in some embodiments, the notch 1001 may be provided at the edge of the beam 100 , so that the seal 120 may be disposed at the edge of the beam 100 . In this way, the seal 120 may be directly installed in the notch 1001 , facilitating the installation of the seal 120 without obstruction, thereby improving assembly efficiency.

In conjunction with FIG. 7 , FIG. 8 , FIG. 9 and FIG. 10 , in some embodiments, in order to facilitate wiring, at least one wire groove 1201 is provided on the seal 120. The number of wire grooves 1201 may be one or more. The wire group 70 is provided in the wire groove 1201, and the wire groove 1201 penetrates the seal 120 so that the wire group 70 can pass through the seal 120 to connect with the control component 602, and the wire groove 1201 guides the direction of the wire group 70 to facilitate the wiring of the wire group 70.

If the width of the wire groove 1201 is too large, the wire assembly 70 will not be unlimited and the wire assembly 70 will easily escape from the wire groove 1201. If the width of the wire groove 1201 is too small, the wire assembly 70 will be difficult to insert into the wire groove 1201. In some embodiments, in order to facilitate the wire assembly 70 to enter the wire groove 1201 and prevent the wire assembly 70 from escaping from the wire groove 1201, the width of the wire groove 1201 matches the diameter of the wire assembly 70.

In the related art, in order to achieve sealing, a wire-passing rubber ring is generally provided on the middle partition of the air conditioner, and the wiring terminal at one end of the wire group is connected to the heat exchanger, and the wiring terminal at the other end passes through the wire-passing rubber ring and is connected to the control component of the electronic control assembly. However, if the wiring terminal of the wire group is large or the angle of the wiring harness is large, in order to allow the wire group to pass through the wire-passing rubber ring, the wire-passing rubber ring needs to be made very large, resulting in poor sealing, increased cost, and great difficulty in wire management and maintenance. In the technical solution according to some embodiments of the present disclosure, a wire-passing groove 1201 is provided on one side of the seal 120, that is, the wire-passing groove 1201 is provided on the end surface of the seal 120 facing the piping pressure plate 110. It can be understood that the wire trough 1201 has an opening. When installing, the piping pressure plate 110 is removed from the shell 40, and the notch 1001 is unobstructed. The seal 120 can be installed in the notch 1001 and fixed on the beam 100. When disassembling and assembling the wire group 70, the opening of the wire trough 1201 is also unobstructed. The middle part of the wire group 70 can be passed through the opening of the wire trough 1201 on the outside of the shell 40 and arranged in the wire trough 1201, or the wire group 70 can be directly pulled out from the opening of the wire trough 1201 in the wire trough 1201. There is no need to pass the wiring terminals of the wire group 70 through the wire trough 1201, which is convenient for disassembling and assembling the wire group 70. There is no need to pull the wire harness, which is convenient for wiring management and has low maintenance difficulty. There is no need to consider the size of the wiring terminals of the wire group or the angle of the wire harness, and there is no need to enlarge the wire trough 1201, which ensures sealing performance and reduces costs.

In conjunction with FIG. 7 , FIG. 8 , FIG. 9 and FIG. 10 , in some embodiments, in order to ensure the sealing performance of the sealing member 120 , a clamping member 140 is provided on the sealing member 120 , and the clamping member 140 is provided in the wire groove 1201 . The wire group 70 entering the wire groove 1201 is clamped by the clamping member 140 , so that the wire group 70 can be prevented from being separated from the wire groove 1201 , and it is also ensured that the wire group 70 is better sealed when passing through the wire groove 1201 , and condensed water is prevented from entering the electric control box 601 through the gap 1001 , thereby ensuring the safety of the control components 602 . In some embodiments, the material of the clamping member 140 and the sealing member 120 can be a rubber with a relatively high hardness, such as polyurethane rubber. If the material of the clamping member 140 and the sealing member 120 is too soft, the wire group 70 can be easily separated from the wire groove 1201 .

In some embodiments, in order to ensure the connection strength between the sealing member 120 and the clamping member 140 , the sealing member 120 and the clamping member 140 may be integrally formed, which is also convenient for preparation.

In combination with Figures 7, 8, 9 and 10, in some embodiments, in order to facilitate the installation of the seal 120, one of the seal 120 and the beam 100 is provided with a clamp, and the other is provided with a mounting groove 1202, and the clamp is clamped in the mounting groove 1202. Through the cooperation between the clamp and the mounting groove 1202, the seal 120 is limited to ensure that the position of the seal 120 is determined, so that the seal 120 can be installed in the notch 1001.

In some embodiments, the seal 120 is provided with a clamp, the cross beam 100 is provided with a mounting groove 1202, and the clamp is clamped in the mounting groove 1202. In other embodiments, the cross beam 100 is provided with a clamp, the seal 120 is provided with a mounting groove 1202, and the clamp is clamped in the mounting groove 1202. Since there is a folded edge on the cross beam 100, the folded edge can be directly used as a clamp. Therefore, in order to reduce the manufacturing difficulty and reduce the manufacturing cost, in some embodiments, the cross beam 100 is provided with a clamp, and the seal 120 is provided with a mounting groove 1202.

In conjunction with FIG. 7, FIG. 8, FIG. 9 and FIG. 10, in some embodiments, in order to ensure the stability of the connection between the seal 120 and the crossbeam 100, a fitting 150 is provided on the seal 120, and the fitting 150 is connected to the crossbeam 100 to fix the seal 120 on the crossbeam 100, to ensure that the position of the seal 120 is determined, and to avoid the position change of the seal 120. In some embodiments, a through hole is provided on the fitting 150, and a fastener passes through the through hole and is connected to the crossbeam 100 to fasten the fitting 150 to the crossbeam 100. In some embodiments, the fastener may be a bolt.

In some embodiments, in order to ensure the connection strength between the sealing component 120 and the fitting component 150 , the sealing component 120 and the fitting component 150 may be integrally formed, which is also convenient for preparation.

In some embodiments, when assembling the air conditioner in the factory, the heat exchanger 50 is first installed in the housing 40, one end of the wire group 70 is connected to the heat exchanger 50, and the other end of the wire group 70 passes through the first support member 80, and then passes through the seal 120 on the cross beam 100, and is connected to the control component 602 in the electric control box 601. Then, the pipe clamp 110 is installed, and the wire group 70 of the water pump assembly 30 of the drainage device on the pipe clamp 110 also passes through the first support member 80, and then passes through the seal 120 on the cross beam 100, and is connected to the control component 602 in the electric control box 601, which is convenient for assembly.

In some embodiments, if the water pump assembly 30 needs to be replaced, the terminal of the corresponding wire group 70 is removed from the control component 602 in the electrical control box 601, the wire group 70 is taken out from the seal 120, and the piping pressure plate 110 is removed from the shell 40. After replacing the water pump assembly 30, the entire piping pressure plate 110 is installed on the shell 40 according to the above-mentioned assembly method, which can facilitate the above-mentioned disassembly and assembly operations and improve the assembly efficiency.

In some embodiments, when it is necessary to replace or overhaul the electric control components on the heat exchanger 50, first remove the piping pressure plate 110 to expose the inspection port 404, then remove the terminal of the corresponding wire group 70 from the control component 602 in the electric control box 601, remove the wire group 70 from the seal 120, replace the new electric control components, and then install them back. If the heat exchanger 50 is equipped with an electronic expansion valve, when replacing the electronic expansion valve, it is necessary to use a welding gun to remove the electronic expansion valve from the pipe group of the heat exchanger 50, and after replacing the new electronic expansion valve, it is necessary to re-weld it to the pipe group of the heat exchanger 50. Thanks to the large space left after removing the piping pressure plate 110, it is convenient for the staff to operate, and it is easy to replace the electrical control components, which improves work efficiency.

In some embodiments, if the water tray 10 needs to be cleaned, the pipe pressing plate 110 is removed, and the water tray 10 can be cleaned or the sterilization and deodorization module on the water tray 10 can be replaced. The dust on the water tray 10 is washed with water, the drain pipe is unblocked, the sewage is discharged, and the sterilization and deodorization module on the water tray 10 is replaced. After completion, the pipe pressing plate 110 is reinstalled. Thanks to the large space left after the pipe pressing plate 110 is removed, it is convenient for the staff to operate, and the water tray 10 is easy to clean, which improves work efficiency.

In some embodiments, in order to control the operation of the heat exchanger 50, the air conditioner also includes a heat exchanger 50 disposed in the shell 40, an electronic control component 60 connected to the shell 40, and a wire group 70 connected to the heat exchanger 50 and the electronic control component 60. The control signal of the electronic control component 60 is transmitted to the heat exchanger 50 through the wire group 70 to control the operation of the heat exchanger 50.

FIG3 is a schematic diagram of the air conditioner in FIG1 in a vertical installation state. In combination with FIG2 and FIG3, since the wire group 70 is connected to the heat exchanger 50, part of the wire group 70 will be close to the pipe 501 of the heat exchanger 50, and when the heat exchanger 50 is working, condensation water will be generated on the wire group 70. In some embodiments, in order to prevent condensation water from entering the electric control component 60 from the wire group 70, the middle part of the wire group 70 is higher than the two ends of the wire group 70, so that the wire group 70 forms a water return structure. Under the action of gravity, the condensation water generated by the wire group 70 due to the proximity of the pipe 501 of the heat exchanger 50 will drip onto the water receiving tray 10, preventing the condensation water from entering the electric control component 60, thereby ensuring the safe operation of the electric control component 60.

In conjunction with FIG. 2 and FIG. 3 , in some embodiments, in order to ensure that the electric control component 60 can control the operation of the heat exchanger 50, the wire group 70 may include: a first wiring segment 701 and a second wiring segment 702. The first wiring segment 701 is connected to the heat exchanger 50. One end of the second wiring segment 702 is connected to the first wiring segment 701, and the other end is connected to the electric control component 60. The control signal of the electric control component 60 is transmitted to the heat exchanger 50 through the first wiring segment 701 and the second wiring segment 702 to control the operation of the heat exchanger 50. In some embodiments, the first wiring segment 701 and the second wiring segment 702 are integrally formed.

In conjunction with Figure 3, in some embodiments, in order to prevent condensation water from entering the electronic control component 60 through the wire group 70, when the air conditioner is in a vertical state, the height of the connection between the first wiring segment 701 and the heat exchanger 50 is less than the height of the connection between the first wiring segment 701 and the second wiring segment 702. Therefore, after the first wiring segment 701 is fixedly connected to the lower part of the heat exchanger 50, it is routed upward to connect with the second wiring segment 702. After the second wiring segment 702 is connected to the first wiring segment 701, it is routed downward to connect with the electronic control component 60, so that the wire group 70 forms a return bend structure, so that the condensation water generated by the wire group 70 due to the proximity of the piping 501 of the heat exchanger 50 falls onto the water receiving tray 10.

In some embodiments, in order to ensure that condensed water generated by the wire group 70 due to the proximity of the piping 501 to the heat exchanger 50 falls onto the water receiving tray 10, the first wiring segment 701 is located above the water receiving tray 10, so that the condensed water generated on the first wiring segment 701 drips into the water receiving tray 10, thereby preventing the condensed water from falling to the outside of the water receiving tray 10, thereby improving the user experience and preventing the condensed water from entering the electronic control component 60, thereby ensuring the safe operation of the electronic control component 60.

In some embodiments, in order to prevent condensation water from entering the electronic control component 60 through the wire group 70, when the air conditioner is in a flat-mounted state, the height of the connection between the first wiring segment 701 and the heat exchanger 50 is also smaller than the height of the connection between the first wiring segment 701 and the second wiring segment 702. Therefore, after the first wiring segment 701 is fixedly connected to the lower part of the heat exchanger 50, it is routed upward to connect with the second wiring segment 702. After the second wiring segment 702 is connected to the first wiring segment 701, it is routed downward to connect with the electronic control component 60, so that the wire group 70 forms a return bend structure, so that the condensation water generated by the wire group 70 due to the proximity of the piping 501 to the heat exchanger 50 falls onto the water receiving tray 10.

In conjunction with FIG. 2 and FIG. 3 , in some embodiments, when the air conditioner is in a flat-mounted state, the water receiving pan 10 is disposed below the fins of the heat exchanger 50 and the first connecting section 701, and the condensed water on the heat exchanger 50 drips into the water receiving pan 10 along the fins, and the condensed water on the first connecting section 701 also drips into the water receiving pan 10. When the air conditioner is in a vertically mounted state, the water receiving pan 10 is disposed below the piping 501 of the heat exchanger 50 and the first connecting section 701. Thus, the water receiving pan 10 covers the entire piping area of the heat exchanger 50, and the condensed water on the heat exchanger 50 drips into the water receiving pan 10 along the piping 501, and the condensed water on the first connecting section 701 also drips into the water receiving pan 10.

In conjunction with FIG. 2 and FIG. 3 , in some embodiments, in order to ensure the stability of the installation of the heat exchanger 50, the air conditioner further includes the heat exchanger 50 disposed in the housing 40, and the air conditioner may further include: a second support member 130. One end of the second support member 130 is connected to the housing 40, and the other end is connected to the heat exchanger 50, so that the second support member 130 supports the heat exchanger 50 and ensures the stability of the installation of the heat exchanger 50.

2 and 3, in some embodiments, the second support member 130 may be connected to the top cover 401 of the housing 40. In other embodiments, the second support member 130 may also be connected to the water receiving tray 10. However, if the second support member 130 is supported by the water receiving tray 10, the structural strength of the water receiving tray 10 will be affected. Therefore, in order to ensure the stability of the second support member 130 supporting the heat exchanger 50, in some embodiments, the second support member 130 is connected to the top cover 401 of the housing 40.

Since the second support member 130 supports the heat exchanger 50, there will be condensed water on the second support member 130. In combination with Figures 2 and 3, in some embodiments, in order to prevent condensed water from entering the electronic control component 60, the second support member 130 is tilted in the shell 40; in some embodiments, when the air conditioner is in a vertical state, the height of the connection between the second support member 130 and the shell 40 is greater than the height of the connection between the second support member 130 and the heat exchanger 50. At this time, the water receiving tray 10 is located below the second support member 130. Under the action of gravity, the condensed water on the second support member 130 will gather at the lowest point of the second support member 130, and then drip into the water receiving tray 10, which can prevent condensed water from entering the electronic control component 60 and ensure the safety of the electronic control component 60.

In some embodiments, when the air conditioner is in a flat-pack state, the height of the connection between the second support member 130 and the shell 40 is greater than the height of the connection between the second support member 130 and the heat exchanger 50. At this time, the water receiving tray 10 is located below the heat exchanger 50. Under the action of gravity, the condensed water on the second support member 130 will gather at the lowest point of the second support member 130, and then flow to the heat exchanger 50, and then drip onto the water receiving tray 10, which can prevent the condensed water from entering the electronic control component 60, thereby ensuring the safety of the electronic control component 60.

6 , in some embodiments, in order to support the piping 501 of the heat exchanger 50 , a supporting groove 1102 is provided on the piping pressing plate 110 , and the piping 501 of the heat exchanger 50 passing through the shell 40 is provided in the supporting groove 1102 , and the piping 501 is supported by the supporting groove 1102 .

In the related art, the wiring method of the indoor unit of the duct air conditioner is as follows: the wire group on one side of the heat exchanger is generally routed from the inside of the shell and then connected to the electrical control box. In this way, the wire group needs to pass through the crossbeam into the area of the shell that supports the fan, and then pass through the electrical control box to connect with the control components. Therefore, it is necessary to thread the wires in the narrow space of the shell. The operating space in the shell is small, and assembly and maintenance are inconvenient and inefficient.

In the technical solutions according to some embodiments of the present disclosure, since a heat exchanger, a beam and a fan are provided in a shell of the air conditioner, the beam is provided between the heat exchanger and the fan, and a notch is provided on the beam, the beam is supported by the shell; since the electric control assembly includes an electric control box provided in the shell and connected to the beam and control components provided in the electric control box, and the electric control box has an opening connected to the notch at the end facing the beam, the electric control box is supported by the shell, and the control components are supported by the electric control box; since one end of the wire group is connected to the heat exchanger, and the other end is successively passed through the notch and the opening to be connected to the control components, there is no need to pass the wire group through the beam into the area of the shell that carries the fan, and there is no need to thread the wires in the narrow space of the shell, thereby making the operating space large, facilitating assembly and maintenance, and achieving high efficiency.
