[0002] At present, the commonly used refrigerants in air-conditioning equipment include R32, R290, R161, etc., which are environmentally friendly, energy-saving and low-cost. However, these environmentally friendly refrigerants have the disadvantage of being "flammable and explosive". When the air conditioner using flammable refrigerants leaks refrigerant, the flammable refrigerant will penetrate into the electric control box. The refrigerant in the electric control box reaches a flammable concentration. At this time, if the electric control board in the electric control box generates electric sparks, it may cause combustion or even explosion.

[0003] At present, the sealing method for the wire holes of the electric control box in the industry is mostly waterproof connectors or aviation connectors. Waterproof connectors are not suitable for multi-wiring harness scenarios. Since the head of the wire group with a plug port is larger than the diameter of the wire harness, the waterproof connector cannot seal the wire hole.

[0041] According to the embodiment of the utility model, a wire passing structure of an electric control box is proposed. Figure 1 , Figure 2 and Figure 4 As shown, the electric control box wire passing structure includes an electric control box 10 , a wire passing connector, a wire passing tube and a plurality of restraining members 40 .

[0042] Specifically, the electronic control box 10 is the control module of the air conditioner. The electronic control box 10 is a control component responsible for controlling the switch, operation mode, temperature adjustment, wind speed adjustment and other functions of the air conditioner. The electronic control box 10 includes a box body 11 and a box cover 12. The interior of the electronic control box 10 defines an electronic control cavity 101. The electronic control cavity 101 is provided with electronic components such as an electronic control mainboard. The electronic components such as the electronic control mainboard in the electronic control cavity 101 are electrically connected to various functional components of the air conditioner (such as a compressor, a fan, a solenoid valve, etc.) through a wiring harness to send control signals or transmit electrical energy to each functional component to control the air conditioner to realize the switch, operation mode, temperature adjustment, wind speed adjustment and other functions.

[0043] The electric control box 10 is provided with a wire hole, which is connected to the electric control cavity 101, so that the wire harness inside the electric control cavity 101 can be electrically connected to various functional components of the air conditioner or external power supply equipment by passing through the wire hole. It can be understood that the number of wire holes can be set to two or more so that different wire harnesses can pass through.

[0044] The wire-passing joint is a tubular part, and the wire-passing joint is connected to the box body 11 by welding. The connecting end of the wire-passing joint and the box body 11 is arranged outside the wire-passing hole, so that the inner cavity of the wire-passing joint is connected to the wire-passing hole. The wire-passing tube includes but is not limited to a silicone tube and a sealing sponge. The wire-passing tube is sleeved outside the wire-passing joint. The wire-passing joint and the wire-passing tube are both used to pass the wire harness. A plurality of binding members 40 are sequentially sleeved outside the wire-passing tube along the length direction of the wire-passing tube, and a part of the binding members 40 among the plurality of binding members 40 are used to tighten and seal the connection portion 321 between the wire-passing tube and the wire-passing joint, and another part of the binding members 40 are used to tighten and seal the part of the wire-passing tube that contacts the wire harness, so as to seal the wire-passing hole. It should be noted that another part of the binding members 40 at least tightens and seals the first end of the wire-passing tube (i.e., the end of the wire-passing tube away from the wire-passing joint). In some embodiments, multiple binding members 40 can be used to form multiple sealing positions between the two ends of the wire tube, rather than just tightening the two ends of the wire tube, so as to improve the sealing effect of the wire hole.

[0045] According to the wire-passing structure of the electric control box of the utility model, after the wire harness is passed through the wire-passing tube, the wire-passing connector and the wire-passing hole, the wire-passing tube is tightly sealed by a plurality of binding members 40 to achieve sealing of the wire-passing hole. Among them. The wire-passing tube is bound by the binding member 40 and is caused to shrink and deform radially to fit tightly to the outer peripheral surface of the wire harness, so that the wire-passing tube can be applied to multiple wire harnesses or wire harnesses of different diameters, and has the advantages of low cost and convenient operation compared to aviation connectors. In addition, the wire-passing hole is sealed by using a wire-passing connector, a soft sealing tank and a plurality of binding members 40, so that the flammable refrigerant leaked in the air conditioner can be prevented from penetrating into the electric control box 10 through the wire hole, and the probability of combustion or explosion of the electric control box 10 is effectively reduced.

[0046] In some embodiments, please combine Figure 1 and Figure 2 As shown, the electric control box wire passing structure also includes a chassis 80, which can be an indoor unit chassis 80 or an outdoor unit chassis 80 of the air conditioner, or the chassis 80 can also be an indoor and outdoor integrated air conditioner chassis 80, and the chassis 80 includes a bottom plate, a top plate and side plates, and the side plates include a rear side plate, a front side plate, a left side plate and a right side plate, and the bottom plate, the top plate and the side plates together enclose the internal space of the chassis 80. The electric control box 10 is installed inside the chassis 80. It should be noted that other functional components of the air conditioner are also arranged inside the chassis 80, such as a compressor, a heat exchanger, a throttling mechanism, a gas-liquid separator, a fan and a refrigerant circulation pipeline.

[0047] In this embodiment, please combine Figure 1 , Figure 3 and Figure 4As shown, the wire connector includes a first connector 21 and a second connector (not shown in the figure), the wire tube includes a first wire tube 31 and a second wire tube 32, and the wire hole includes a first wire hole 111 and a second wire hole 112. Specifically, the first connector 21 and the first wire tube 31 cooperate to form an external wire harness enclosed structure of the external wire harness between the sealed electric control box 10 and the side plate of the chassis 80, and the second connector and the second wire tube 32 cooperate to form an internal wire harness enclosed structure that electrically connects the electric control box 10 to the internal components of the air conditioner. It should be pointed out that the external wire harness refers to a conductive wire harness connecting the electric control box 10 and an external device (such as a power supply device) outside the air conditioner. For example, the external wire harness can be a power supply wire, and the internal wire harness refers to a conductive wire harness connecting the electric control box 10 and various functional devices in the air conditioner. The internal wire harness can transmit control signals or transmit electrical energy between the electric control box 10 and various functional devices in the air conditioner.

[0048] In detail, the first connector 21 is a tubular member and is connected to the outer wall of the electric control box 10 by welding, that is, the first connector 21 is arranged in the chassis 80 and outside the electric control cavity 101, and the inner cavity of the first connector 21 is connected to the first wire hole 111. The first end of the first wire tube 31 is sleeved outside the first connector 21, and the second end of the first wire tube 31 is connected to the side plate 81 of the chassis 80. The external wire harness can be passed through the first wire tube 31, the first connector 21 and the first wire hole 111, so that the two ends of the external wire harness can be electrically connected to the electronic components such as the electric control mainboard in the electric control box 10 and external devices respectively. A plurality of binding members 40 are also sleeved on the first wire passing tube 31, and a part of the binding members 40 tightly seal the connection between the first wire passing tube 31 and the first connector 21, while another part of the binding members 40 at least tightly seal the connection between the first wire passing tube 31 and the side panel 81 of the chassis 80, thereby isolating and sealing the external wiring harness from the internal space of the chassis 80.

[0049] Among them, a wiring hole 811 for the external wiring harness to pass through is provided on the side panel 81 of the chassis 80, so that the external wiring harness can extend from the wiring hole 811 to the outside of the chassis 80 and be connected to an external device. In this embodiment, the first wire tube 31 is passed through the wiring hole 811, and the second end of the first wire tube 31 extends out of the chassis 80 through the wiring hole 811. It can be understood that extending the second end of the first wire tube 31 to the outside of the chassis 80 through the wiring hole 811 can further reduce the probability of the flammable refrigerant leaking from the air conditioner penetrating into the electric control box 10 through the first wire hole 111, and effectively prevent the electric control box 10 from burning or exploding. The side panel 81 in this embodiment can be any one of the rear side panel, the right side panel and the front panel of the chassis 80.

[0050] It is understandable that in other embodiments, such as Figure 1As shown, a third joint (not shown in the figure) communicating with the wiring hole 811 can be provided on the inner wall of the side plate 81 of the chassis 80. The structure of the third joint is the same as that of the first joint 21, the first end of the first wire tube 31 is sleeved outside the first joint 21, the second end of the first wire tube 31 is sleeved outside the third joint, and a part of the number of binding members 40 is used to tighten the first wire tube 31 and the first joint 21 to seal the connection between the two, and another part of the number of binding members 40 is used to tighten the first wire tube 31 and the third joint to seal the connection between the two, thereby isolating and sealing the first wire hole 111 and the external wiring harness from the internal space of the chassis 80.

[0051] like Figure 4 As shown, the second connector is a tubular part and is connected to the outer wall of the electric control box 10 by welding, and the inner cavity of the second connector is connected to the second wire hole 112. The second wire tube 32 is a silicone tube or a sealed sponge tube, and the second wire tube 32 includes a connecting portion 321 and a sealing portion 322 that are connected and communicated. The connecting portion 321 is a tubular structure, and the connecting portion 321 is sleeved outside the second connector and is tightened by at least one binding member 40, so that the connecting portion 321 is sealed and connected to the second connector. The sealing portion 322 is a tubular structure, and one end of the sealing portion 322 is connected to the connecting portion 321. The internal wiring harness can be passed through the second wire tube 32, the second connector and the second wire hole 112, so that the two ends of the internal wiring harness can be electrically connected to electronic components such as the electric control motherboard in the electric control box 10 and various functional components in the air conditioner. Among the multiple binding members 40, a part of the binding members 40 are sleeved on the outside of the connecting portion 321 and the connecting portion 321 is fastened to the second joint, and the connection between the second wire tube 32 and the second joint is fastened and sealed, and another part of the binding members 40 are sleeved on the outside of the sealing portion 322 and the sealing portion 322 is fastened and sealed, so that the sealing portion 322 shrinks and deforms along its own radial direction under the binding action of the binding members 40, so that the inner wall of the sealing portion 322 fits tightly to the outer peripheral surface of the internal wiring harness, thereby sealing the second wire hole 112, isolating the electric control cavity 101 from the internal space of the chassis 80, reducing the probability of flammable refrigerant leaking from the air conditioner penetrating into the electric control box 10 through the second wire hole 112, and effectively preventing the electric control box 10 from burning or exploding.

[0052] In some embodiments, Figure 4As shown, the sealing portion 322 is a bent tubular structure, one end of the sealing portion 322 is connected to the connecting portion 321, and the other end of the sealing portion 322 is bent in the opposite direction by 180°, so that the sealing portion 322 forms a first sealing segment 3221 connected to the connecting portion 321 and a second sealing segment 3222 connected to one end of the first sealing segment 3221 away from the connecting portion 321 and bent back by 180° relative to the first sealing segment 3221. Along the length direction of the sealing portion 322, at least one binding member 40 is respectively arranged at the head, middle and tail of the sealing portion 322, each binding member 40 is sleeved outside the first sealing segment 3221 and the second sealing segment 3222, and is fastened and fixed by the binding member 40, so as to form a plurality of sealing positions on the sealing portion 322, so as to further enhance the sealing effect of the second wire hole 112.

[0053] It should be noted that the restraining member 40 in this embodiment includes but is not limited to a tightening belt and a throat clamp.

[0054] The first wire passing tube 31 and the second wire passing tube 32 can be soft elastic tubes such as silicone tubes, rubber tubes, and wire passing tubes formed by wrapping the wire body with sealing sponges, or they can be hard tubes with good deformation properties, as long as they meet the sealing requirements and achieve the same sealing function.

[0055] In this embodiment, please combine Figure 5 and Figure 6 As shown, the electric control box wire passing structure also includes a radiator 50 and a sealing ring 60. The electric control box 10 is provided with a heat dissipation hole 113. The radiator 50 and the electric control box 10 are fixedly connected by bolts and other connecting parts. The radiator 50 covers the heat dissipation hole 113. The electric control mainboard inside the electric control box 10 or the electronic components integrated on the electric control mainboard are thermally connected to the radiator 50 so as to dissipate heat through the radiator 50. The sealing ring 60 is arranged outside the heat dissipation hole 113 and is clamped between the electric control box 10 and the radiator 50. The pre-tightening force applied by the bolts to the radiator 50 and the electric control box 10 is used to squeeze the sealing ring 60, so as to seal the heat dissipation hole 113, reduce the probability of the flammable refrigerant leaking from the air conditioner penetrating into the electric control box 10 through the heat dissipation hole 113, and effectively prevent the electric control box 10 from burning or exploding.

[0056] Furthermore, a groove (not shown in the figure) is provided along the circumference of the radiator 50, and the sealing ring 60 is sleeved on the outside of the radiator 50 and located in the groove. The groove on the radiator 50 is used for pre-fixing the sealing ring 60. During the assembly process, the sealing ring 60 is first sleeved in the groove of the radiator 50, and then the radiator 50 and the sealing ring 60 are installed on the electric control box 10 by bolts, and the sealing ring 60 is clamped between the outer wall surface of the electric control box 10 and the side wall surface of the groove of the radiator 50. The pre-tightening force applied to the radiator 50 and the electric control box 10 by the bolts makes the sealing ring 60 pressurized and interference fit to achieve the sealing of the heat dissipation hole 113.

[0057] In this embodiment, please combine Figure 6 and Figure 7 As shown, the electric control box 10 includes a box body 11 and a box cover 12 hinged to the box body 11, the box body 11 is a rectangular box-shaped structure, the box body 11 includes a base plate for mounting the radiator 50, a first side plate connected to the base plate, a second side plate, a third side plate and a fourth side plate, the first side plate, the second side plate, the third side plate and the fourth side plate are connected end to end in sequence, and the ends of the first side plate, the second side plate, the third side plate and the fourth side plate facing away from the base plate are bent toward the side facing away from the electric control cavity 101 to form a sealing surface (not shown in the figure). The box cover 12 is detachably mounted on the sealing surface by screws, or the box cover 12 is hinged to the box body 11 by hinges, and is used to open or close the electric control chamber 101, so as to facilitate the installation or debugging and maintenance of the electronic components inside the electric control box 10. The sealing surface is paved with a sealing member 70. When the box cover 12 is in a closed state, the sealing member 70 is clamped between the box body 11 and the box cover 12, and the sealing member 70 is pressed to have an interference fit with the box body 11 and the box cover 12 to achieve sealing. The sealing member 70 includes but is not limited to sponges and silicone parts.

[0058] In this embodiment, the box body 11 can be an integrated structure, for example, formed in one piece by injection molding or sheet metal processing; the box body 11 can also be an assembly of multiple plate-like parts processed by welding, bonding, fusion connection, etc.
