[0046] Considering that the top-mounted air conditioner 1000 is installed on the roof of the vehicle, and its internal electrical reliability and the like face more complex operating environments as the whole vehicle bounces and drives, it is necessary to reasonably design to ensure electrical safety performance. In the related art, most of the fixing is near the outlet of the electric control box assembly 500, which is not a systematic whole machine wiring fixing scheme. The overall wiring configuration has problems, the electrical safety cannot be fully guaranteed, the wire fixing method relies on external auxiliary parts, the cost cannot be maximized, and the operation efficiency is not high.

[0047] Based on this, the embodiment of the present application sets the wire fixing mechanism 900 on the inner air duct fixing cover 330 or the outer air duct fixing part 420, the wire fixing mechanism 900 is used to fix the wire connected between the installation component and the electric control box assembly 500, the wire fixing mechanism 900 and the inner air duct fixing cover 330 or the outer air duct fixing part 420 can adopt an integrated structure, for example, the wire fixing mechanism 900 can be a wire buckle, a wire groove or the like structure, without the need to additionally increase auxiliary parts, of course, the wire fixing mechanism 900 can also be set on the inner air duct fixing cover 330 and the outer air duct fixing part 420 at the same time, so that the wiring structure is more stable and reliable, the wire fixing mode is more reasonable, the wiring of the installation component is facilitated to be straightened, the cost investment is reduced, and the assembly efficiency is improved.

[0048] Referring to Figure 2 and Figure 3 As shown in the figure, the inner air duct fixing cover 330 and the outer air duct fixing part 420 are respectively provided with a plurality of wire fixing hooks, by distributing the plurality of wire fixing hooks at different positions of the inner air duct fixing cover 330 and the outer air duct fixing part 420, the wiring of the installation component can be reasonably fixed. Specifically, the compressor 600 is installed on the right side of the base plate 100, the first wire fixing hook 331 is arranged on the side of the inner air duct fixing cover 330 close to the compressor 600, the first wire fixing hook 331 is used to fix the first wire between the electric control box assembly 500 and the compressor 600, the first wire is also called the compressor wire 610, the compressor wire 610 is fixed at the first wire fixing hook 331 after being led out from the wire outlet at the top position, so that the compressor wire 610 is fixed near the wire outlet. The first wire fixing hook 331 is a hook structure, the size of the hook structure is adjusted according to the size of the wire body, and the specific shape is not limited, the wire can be directly buckled at the first wire fixing hook 331 during assembly, without the need to additionally increase auxiliary parts for fixing, and the operation is simple and fast.

[0049] In combination with Figure 4 It can be understood that in the height direction of the top-mounted air conditioner 1000, the height of the first wire fixing hook 331 is less than the height of the wire outlet of the compressor 600, the compressor wire 610 is first fixed downward at the first wire fixing hook 331, and then is wired upward, after assembly, the compressor wire 610 forms a downward backwater bend near the wire outlet position, which can effectively prevent the wire body from leading water to the wire outlet of the compressor 600, and avoid the erosion and damage of water.

[0050] Referring to Figure 2As shown, it can be understood that the top of the inner air duct fixing cover 330 is provided with three second wire hooks 332, which are arranged in intervals in the direction of the compressor 600 towards the electric control box assembly 500. After the compressor wire 610 passes through the first wire hook 331, it extends upwards and continues to be wired along the top of the inner air duct fixing cover 330. The wire body at the top position is fixed by the second wire hook 332, and the wire body enters the electric control box assembly 500, so that the wiring between the compressor 600 and the electric control box assembly 500 can be effectively fixed.

[0051] It should be noted that the electric control box assembly 500 is located at the top of the inner air duct fixing cover 330, and the outer periphery of the box body of the electric control box assembly 500 is provided with a plurality of wire inlet ports for entering the wiring. Among them, the wire inlet port of the compressor wire 610 is arranged close to the second wire hook 332, so that the compressor wire 610 can enter the electric control box assembly 500 in a straight line after passing through the second wire hook 332, which is beneficial to reduce the length of the wire body, so that the wiring is more reasonable and fixed, and avoids scattered arrangement. It is worth pointing out that the wire inlet port position of the electric control box assembly 500 can be arranged higher than the position of the second wire hook 332, so that the wire body is not easy to enter the electric control box assembly 500, thereby reducing the risk of water entering the electric control box assembly 500.

[0052] In addition, the second wire hook 332 can adopt the same hook form as the first wire hook 331, and the number of the second wire hook 332 is not limited to the number shown in the above embodiment. The number of the second wire hook 332 can be set according to actual use requirements, so as to avoid the wire body at the top of the inner air duct fixing cover 330 from being scattered, for example, two or more second wire hooks 332 can be arranged, and the specific number is not limited.

[0053] It is worth pointing out that the top of the inner air duct fixing cover 330 in the embodiment is provided with a first wire passing groove 333, which extends in the direction of the compressor 600 towards the electric control box assembly 500. The opening of the first wire passing groove 333 is arranged upwards, and the second wire hook 332 is distributed along the opening of the first wire passing groove 333. Specifically, one end of the second wire hook 332 is connected with the side wall of the first wire passing groove 333, and the other end extends above the first wire passing groove 333 and is arranged in intervals with the other side wall, so that the wire body of the compressor 600 can be wired along the first wire passing groove 333, and the wire body is compressed by the second wire hook 332, so that the wiring is more straight, and the wire body can also be effectively protected.

[0054] Referring to Figure 2As shown, in some embodiments, the compressor 600 is provided with an exhaust pipe temperature sensing wire 620, through which the temperature of the exhaust pipe of the compressor 600 is detected, and the working condition of the compressor 600 can be known according to the temperature of the exhaust pipe. The exhaust pipe temperature sensing wire 620 is fixed at the top of the exhaust pipe of the compressor 600, and then the wire body is straightened and enters the first wire passing groove 333, and is fixed through the second wire fixing hook 332, so that the exhaust pipe temperature sensing wire 620 enters the wire inlet of the side part of the electric control box assembly 500 along the first wire passing groove 333.

[0055] Referring to Figure 2 and Figure 6 As shown, it can be understood that the inner air duct assembly 300 includes an inner air fan 340, and the inner air fan 340 includes an inner motor 341 and a cross-flow fan wheel 342, wherein the inner motor 341 is located on the right side of the inner air duct member 320 and is fixedly connected with the chassis 100, and a cover body 337 is arranged on the right side of the inner air duct fixing cover 330, and the cover body 337 covers the inner motor 341 after the inner air duct fixing cover 330 is assembled in place. A third wire fixing hook 334 is arranged on the right side wall of the inner air duct fixing cover 330, and the third wire fixing hook 334 is located between the wire outlet position of the inner motor 341 and the second wire fixing hook 332. The number of the third wire fixing hook 334 can be one or more, and is not limited in particular. The third wire fixing hook 334 cooperates with the second wire fixing hook 332 to fix a second wire line between the inner air fan 340 and the electric control box assembly 500. The second wire line is also referred to as an inner motor wire 343. The inner motor wire 343 is wired from a position close to the chassis 100, then extends upwardly through the third wire fixing hook 334, is fixed after passing through the third wire fixing hook 334, then continues to extend upwardly into the first wire passing groove 333, and finally enters the electric control box assembly 500 along the first wire passing groove 333. The side part of the electric control box assembly 500 is provided with a wire inlet corresponding to the inner motor wire 343 near the edge of the inner air duct fixing cover 330, so that the wiring of the inner motor 341 can enter the electric control box assembly 500 straightly.

[0056] Referring to Figure 2 As shown, in some embodiments, the right side wall of the inner air duct fixing cover 330 is further provided with a second wire passing groove 335 perpendicular to the first wire passing groove 333. The second wire passing groove 335 extends obliquely from the wire outlet position close to the inner motor 341 towards the first wire passing groove 333. The third wire fixing hook 334 is arranged in the second wire passing groove 335. In this way, the inner motor wire 343 can be wired in sequence through the second wire passing groove 335 and the first wire passing groove 333. The wire line is pressed against the wire body by the third wire fixing hook 334 when passing through the second wire passing groove 335, and is pressed against the wire body by the second wire fixing hook 332 when passing through the first wire passing groove 333, so that the inner motor wire 343 is effectively fixed.

[0057] Referring to Figure 6As shown, it is worth pointing out that the chassis 100 is provided with a support seat 130, the inner motor 341 is fixedly installed in the support seat 130, a side wall of the support seat 130 is provided with a wire outlet slot 131, and the inner motor wire 343 is wired from the wire outlet slot 131; referring to Figure 7 and Figure 8 As shown, the inner air duct fixed cover 330 is provided with a wire pressing column 338, the wire pressing column 338 is located at the bottom of the cover body 337 and extends downward, and the wire pressing column 338 is integrally formed with the inner air duct fixed cover 330.

[0058] Combined with Figure 9 and Figure 10 It can be understood that after the inner air duct fixed cover 330 is assembled in place, the cover body 337 is covered on the support seat 130, at this time the wire pressing column 338 presses the wire body downward, so that the wire is bent downward to form a backwater bend, and then the wire is wired along the wire outlet slot 131, and the backwater bend can effectively prevent the wire body from leading water into the inner motor 341, thereby reducing the risk of water entering the inner motor 341.

[0059] It should be noted that the inner motor wire 343 is wired along the first wire passing slot 333 together with the compressor wire 610 and the exhaust pipe temperature sensing wire 620, and the second wire fixing hook 332 can be used to fix the three wire bodies at the same time, which is beneficial to simplify the wire fixing mechanism 900 and make the wiring more reasonable and save the length of the wire. It can be understood that the inner air duct fixed cover 330 is fixedly connected with the chassis 100, and after being fastened, the inner air duct fixed cover 330 presses the entire inner air duct member 320 downward, and supports the electric control box assembly 500 at the top. By cooperation of the first wire passing slot 333, the second wire passing slot 335, the first wire fixing hook 331, the second wire fixing hook 332 and the third wire fixing hook 334, the wire can be fixed, which can effectively prevent the wire from being relatively pulled.

[0060] Referring to Figure 3 As shown, it can be understood that the top-mounted air conditioner 1000 needs to be powered by a vehicle, and needs to be connected to the electric control box assembly 500 from the house car interior through the power supply wire 541. Since the indoor air inlet 110 is communicated with the house car interior, the power supply wire 541 can be led out from the electric control box assembly 500 and then enter the house car interior through the indoor air inlet 110. Specifically, the side of the electric control box assembly 500 away from the compressor 600 is provided with a wire inlet of the power supply wire 541, and the fourth wire fixing hook 336 is arranged at the left side of the inner air duct fixed cover 330, close to the wire inlet of the power supply wire 541 and below the electric control box assembly 500.

[0061] Combined with Figure 5 and Figure 6It can be understood that the side wall of the indoor air inlet 110 is provided with a fifth fixed line hook 140, and the third line 540 at least including the power line 541 described above can be fixed by cooperation of the fourth fixed line hook 336 and the fifth fixed line hook 140, so that the power line 541 is effectively fixed. It should be noted that, in order to display the working state of the top-mounted air conditioner 1000 and other information in real time in the vehicle, the line of the display panel needs to enter the whole machine through the indoor air inlet 110 and be connected with the electric control box assembly 500, and the line of the display panel is also called a signal line 542. Therefore, in the embodiment, the power line 541 and the signal line 542 are combined into the third line 540, and the third line 540 is fixed at the fourth fixed line hook 336 and the fifth fixed line hook 140.

[0062] Referring to Figure 5 and Figure 6 It can be understood that the side wall of the indoor air inlet 110 is provided with a fifth fixed line hook 140, and the third line 540 at least including the power line 541 described above can be fixed by cooperation of the fourth fixed line hook 336 and the fifth fixed line hook 140, so that the power line 541 is effectively fixed. It should be noted that, in order to display the working state of the top-mounted air conditioner 1000 and other information in real time in the vehicle, the line of the display panel needs to enter the whole machine through the indoor air inlet 110 and be connected with the electric control box assembly 500, and the line of the display panel is also called a signal line 542. Therefore, in the embodiment, the power line 541 and the signal line 542 are combined into the third line 540, and the third line 540 is fixed at the fourth fixed line hook 336 and the fifth fixed line hook 140.

[0063] Referring to Figure 6 It can be understood that the side wall of the indoor air inlet 110 is provided with a fifth fixed line hook 140, and the third line 540 at least including the power line 541 described above can be fixed by cooperation of the fourth fixed line hook 336 and the fifth fixed line hook 140, so that the power line 541 is effectively fixed. It should be noted that, in order to display the working state of the top-mounted air conditioner 1000 and other information in real time in the vehicle, the line of the display panel needs to enter the whole machine through the indoor air inlet 110 and be connected with the electric control box assembly 500, and the line of the display panel is also called a signal line 542. Therefore, in the embodiment, the power line 541 and the signal line 542 are combined into the third line 540, and the third line 540 is fixed at the fourth fixed line hook 336 and the fifth fixed line hook 140.

[0064] It should be noted that in some embodiments, the evaporator 310 may be equipped with an evaporator pipe temperature sensing wire (not shown in the attached diagram). This evaporator pipe temperature sensing wire extends downwards from the evaporator 310 and passes through the indoor air inlet 110 into the vehicle interior. The evaporator pipe temperature sensing wire and the indoor ambient temperature sensing wire 551 form a fourth line 550, which is fixed to the indoor air inlet 110 using a sixth wire hook 150. It is worth noting that the fifth wire hook 140 and the sixth wire hook 150 are spaced apart to avoid electromagnetic interference between the wires. Figure 1 It is understood that the third line 540 and the fourth line 550 both exit from the indoor air inlet 110 to avoid the problem of condensation on the line. In the embodiment, the fifth wire hook 140 is located on the side wall of the indoor air inlet 110 away from the compressor 600, and the sixth wire hook 150 is located on the side wall of the indoor air inlet 110 close to the compressor 600.

[0065] It should be noted that the roof-mounted air conditioner 1000 in this embodiment of the invention is an inverter air conditioner. The power cord 541, signal cord 542, indoor ambient temperature sensing wire 551, and evaporator pipe temperature sensing wire all extend downward from the indoor air inlet 110 and then enter the RV interior. The power cord 541 is directly connected to the RV power supply line. The signal cord 542, indoor ambient temperature sensing wire 551, and evaporator pipe temperature sensing wire can be connected to the control display panel inside the RV. The wiring fixing mechanism 900 of the above embodiment can complete the installation of the entire roof-mounted air conditioner 1000 on the RV and the fixing of the wiring.

[0066] Furthermore, it should be noted that in this embodiment, the wiring is routed through the indoor air inlet 110 to realize the installation of power supply and control lines for the entire unit's operation. This avoids the design of separately opening a wiring port on the chassis 100 of the entire unit, preventing water leakage into the RV interior through the wiring port. Moreover, the wiring enters the RV interior through the indoor air inlet 110, rather than through the indoor air outlet 120. This also avoids all wires being cooled by the low-temperature cold air generated by the refrigeration system when the wiring is routed through the indoor air outlet 120. This further avoids the formation of condensation on the wire surface due to various factors such as the wire heating up due to cold, internal heating, or intermittent shutdown, which could cause water to enter the wiring terminals and cause short circuits and leakage, thus greatly improving the electrical safety performance of the entire unit.

[0067] Reference Figure 2 As shown, in some embodiments, the mounting components also include a reactor 700, which is fixed to the chassis 100 and located below the electrical control box assembly 500, in conjunction with... Figure 6It can be understood that the line of the electric reactor 700 is called the electric reactor line 710, which is out of the side close to the inner air duct fixing cover 330, the line body is bent upward and fixed at the fourth wire fixing hook 336, and finally extends upward and bends towards the rear of the whole machine and extends into the electric control box assembly 500.

The outer motor 431 is assembled at the middle part of the mounting bracket 440, and the outlet terminal of the outer motor 431 extends downward at the rear, the fifth line is also called the outer motor line 433, the outer motor line 433 first extends downward in a straight line, then bends upward, and is clamped at the seventh wire fixing hook 421 at the bending position, the line body continuously stretched upward passes through the top of the outer air duct fixing member 420 and is clamped and fixed by the eighth wire fixing hook 422, then bends and walks into the electric control box assembly 500 along the left and right directions of the whole machine, it should be noted that the outer motor line 433 enters the electric control box assembly 500 from the middle of the side of the electric control box assembly 500 to the inlet of the outer air duct fixing member 420.

[0069] Referring to Figure 2As shown, in the embodiment, the condenser 410 is provided with an outlet pipe temperature sensing wire 411, and the top of the outer air duct fixing member 420 is provided with a ninth wire fixing hook 423. In the embodiment, the ninth wire fixing hook 423 is provided with two, and the two ninth wire fixing hooks 423 are distributed along the top of the outer air duct fixing member 420 at intervals. It can be understood that the eighth wire fixing hook 422 is located at the middle position of the top of the outer air duct fixing member 420 and is close to the electric control box assembly 500, and the two ninth wire fixing hooks 423 are distributed close to the right side of the outer air duct fixing member 420. The end of the outlet pipe temperature sensing wire 411 is inserted and fixed on the pipeline of the condenser 410, and then the wire body passes through the ninth wire fixing hook 423 and the eighth wire fixing hook 422 in turn and is clamped and fixed upwards along the top of the outer air duct fixing member 420, and finally enters the wire inlet close to the edge of the outer air duct fixing member 420 on the side of the electric control box assembly 500. It should be noted that the outlet pipe temperature sensing wire 411 and the outer motor wire 433 are fixed at the eighth wire fixing hook 422 together, so that the two wires can enter the electric control box assembly 500 straightly, and the wiring is more reasonable. In addition, the eighth wire fixing hook 422 and the ninth wire fixing hook 423 can specifically adopt the form of buckles, so as to facilitate the clamping of the wire body.

It can be understood that this position is close to the air inlet grille 210 of the top cover 200, so as to facilitate sensing the outdoor air inlet environment temperature.

[0071] It should be noted that the side of the electric control box assembly 500 can also be provided with a tenth wire fixing hook 530 for fixing the outdoor environment temperature sensing wire 510, which is specifically set according to actual use requirements. In some embodiments, the second wire fixing clamp 520 can also be arranged at a position close to the air inlet grille 210 of the outer air duct fixing member 420, so as to enable the outdoor environment temperature sensing wire 510 to sense the outdoor air inlet environment temperature.
