An air duct machine 100 according to an embodiment of the present utility model is described below with reference to fig. 1 to 12.

As shown in connection with fig. 1-3, an air duct machine 100 according to the present utility model may mainly include: the shell 10, the electrical apparatus box 20, the heat exchanger 30, the heat exchange fan 40 and the vortex piece 50, wherein, the electrical apparatus box 20, the heat exchanger 30, the heat exchange fan 40 and the vortex piece 50 are all arranged in the shell 10, so that the shell 10 can play a role in protecting the electrical apparatus box 20, the heat exchanger 30, the heat exchange fan 40 and the vortex piece 50, prevent the electrical apparatus box 20, the heat exchanger 30, the heat exchange fan 40 and the vortex piece 50 from being damaged due to the erosion of external foreign matters or the impact of external force, thereby improving the structural reliability of the air duct machine 100, ensuring that the air duct machine 100 can work normally, and ensuring the normal heat exchange of the heat exchanger 30 and the heat exchange fan 40 by electrically connecting the heat exchanger 30 and the heat exchange fan 40, ensuring the normal operation of the heat exchanger 30 and the heat exchange fan 40, and controlling the working states of the heat exchanger 30 and the heat exchange fan 40, and realizing the control of different working modes of the air duct machine 100.

Further, by arranging the air inlet 11 and the air outlet 12 which are spaced from each other on the casing 10, the electrical box 20 is arranged in the casing 10 and is adjacent to the air outlet 12, the heat exchanger 30 is adjacent to the air inlet 11 and is spaced from the electrical box 20, and the heat exchange fan 40 is positioned between the heat exchanger 30 and the electrical box 20, so that the air flow outside the casing 10 can be introduced into the casing 10 through the air inlet 11 through the operation of the heat exchange fan 40, and the heat exchange air flow is formed through the heat exchange of the heat exchanger 30, so that the cooling and dehumidification of the indoor air are realized, and then the heat exchange air flow is output to the outside of the casing 10 through the air outlet 12 under the driving of the heat exchange fan 40, thereby realizing the normal operation of the air duct machine 100.

The heat exchanger 30 may mainly include: the first heat exchanger 31 and the second heat exchanger 32, one end of the first heat exchanger 31 adjacent to the air inlet 11 and one end of the second heat exchanger 32 adjacent to the air inlet 11 are connected, the first heat exchanger 31 and the second heat exchanger 32 are gradually far away from each other in the direction extending from the air inlet 11 to the air outlet 12, so that a certain included angle is formed between the first heat exchanger 31 and the second heat exchanger 32, the heat exchanger 30 is in an inverted V-shaped structure in the direction extending from the air inlet 11 to the air outlet 12, on one hand, the overall size of the air duct machine 100 can be reduced, transportation and installation are convenient, on the other hand, condensed water generated on the heat exchanger 30 is prevented from dripping down to the water receiving disc 70 below in a homeotropic manner, and the heat dissipation efficiency of the heat exchanger 30 is prevented from being influenced by the condensed water gathering on the heat exchanger 30, so that the heat exchange performance and the assembly efficiency of the air duct machine 100 can be effectively improved.

As such, the ducted air machine 100 in the present application performs a refrigerating cycle of the ducted air machine 100 by using the compressor, the expansion valve, and the heat exchanger 30. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged. The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the heat exchanger 30. The heat exchanger 30 condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the heat exchanger 30 into a low-pressure liquid-phase refrigerant. The heat exchanger 30 evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low temperature and low pressure state to the compressor. The heat exchanger 30 may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. Throughout the cycle, the air duct machine 100 may adjust the temperature of the indoor space to meet the use demands of the user. Further, the heat exchange fan 40 of the present application can accelerate the flow rate of the wind flowing through the heat exchanger 30, so as to improve the heat exchange efficiency of the air duct machine 100 and improve the working performance of the air duct machine 100.

Referring to fig. 9-12, the spoiler 50 is disposed between the first heat exchanger 31 and the second heat exchanger 32, and includes a first spoiler 51 and a second spoiler 52, where the first spoiler 51 is attached to a side of the first heat exchanger 31 facing the second heat exchanger 32, one end of the first spoiler 51 adjacent to the air inlet 11 abuts against one end of the second heat exchanger 32 adjacent to the air inlet 11, one end of the second spoiler 52 is connected to one end of the first spoiler 51 away from the air inlet 11, and the other end of the second spoiler 52 extends toward the second heat exchanger 32 and abuts against the second heat exchanger 32.

Specifically, considering that when the air duct machine 100 is installed upside down, the air inlet 11 is located above, the air outlet 12 is located below, and the heat exchanger 30, the heat exchange fan 40 and the electrical box 20 are sequentially arranged at intervals from top to bottom, so that the factors such as uneven distribution of the evaporator and gravity of the refrigerant are received, the flow rate of the top of the heat exchanger 30 is high, the hot and humid air is not fully subjected to heat exchange and cooling, the hot and humid air directly enters the inside of the shell 10, the lower part of the heat exchanger 30 has better heat exchange and cooling effects, the temperature of the air passing through the heat exchanger 30 is lower, so that a large temperature difference exists in the air passing through the heat exchanger 30, the temperature of the low-temperature air is close to the temperature of the low-temperature air in the process of being blown out by the heat exchange fan 40, and the temperature of the volute is continuously contacted with the low-temperature air, so that after the hot and humid air at the top is contacted with the low-temperature volute, water is continuously condensed and separated out on the surface of the low-temperature air, the condensed dew is more and more finally flows downwards to the upper part of the electrical box 20 under the action of gravity, and enters the electrical box 20 through a gap at the upper part of the electrical box 20, and drops to an electric device, and serious safety risk is generated.

The spoiler 50 is arranged between the first heat exchanger 31 and the second heat exchanger 32, so that the first spoiler 51 is attached to one side of the first heat exchanger 31 facing the second heat exchanger 32, one end of the first spoiler 51 adjacent to the air inlet 11 is attached to one end of the second heat exchanger 32 adjacent to the air inlet 11, one end of the second spoiler 52 is connected with one end of the first spoiler 51 away from the air inlet 11, the other end of the second spoiler 52 extends towards the second heat exchanger 32 and is attached to the second heat exchanger 32, the cross section of the spoiler 50 is triangular, and the one end of the first spoiler 51 away from the air inlet 11 is attached to one side of the first heat exchanger 31 facing the second heat exchanger 32, so that the spoiler 50 can seal an upper space between the first heat exchanger 31 and the second heat exchanger 32.

So set up, on the one hand, can reduce the air velocity, make the heat transfer of gas in first heat exchanger 31 and second heat exchanger 32 more abundant, on the other hand, first spoiler 51 can change the direction of gas flow, make the top air current flow through first heat exchanger 31 or second heat exchanger 32 many times and exchange heat, make the gas can pass through the better position of heat transfer, thereby make the heat transfer of gas in first heat exchanger 31 and second heat exchanger 32 more even, so, can realize that heat exchanger 30 is to indoor gas cooling dehumidification more abundant even, make the temperature homogeneity of the heat transfer air current that flows to heat transfer fan 40 better, thereby can solve the condensation problem of heat transfer fan 40 from the source, can avoid the condensate water drip to electric apparatus box 20 on, can promote the security performance of tuber pipe machine 100.

Therefore, through the arrangement of the turbulence piece 50, the indoor air can be cooled and dehumidified more fully and uniformly by the heat exchanger 30, so that the temperature uniformity of the heat exchange air flow flowing to the heat exchange fan 40 is better, the condensation problem of the heat exchange fan 40 can be solved, the condensation water is prevented from dripping onto the electrical box 20, and the safety performance of the air duct machine 100 can be improved.

Referring to fig. 9-12, a sealing flange 521 is disposed at an end of the second spoiler 52 away from the first spoiler 51, the sealing flange 521 is bent with respect to the second spoiler 52, and the sealing flange 521 is attached to a side of the second heat exchanger 32 facing the first heat exchanger 31. Specifically, the sealing flange 521 is disposed at one end of the second spoiler 52 far away from the first spoiler 51, and the sealing flange 521 is bent and disposed opposite to the second spoiler 52, so that a cross section formed by the spoiler 50 and one of the first heat exchanger 31 and the second heat exchanger 32 is triangular, which is favorable for improving structural strength of the spoiler 50, and the sealing flange 521 and one side of the second heat exchanger 32 facing the first heat exchanger 31 are disposed in a fitting manner, so that one end of the second spoiler 52 far away from the first spoiler 51 is tightly fitted with one of the second heat exchangers 32, sealing performance between the spoiler 50 and the heat exchanger 30 is improved, leakage of gas from between the heat exchanger 30 and the spoiler 50 is prevented, and gas flow flowing back to the heat exchanger 30 from the spoiler 50 is ensured, thereby improving uniformity of gas heat exchange.

As shown in fig. 9-11, the sealing flange 521 and the end, adjacent to the air inlet 11, of the second heat exchanger 32 are arranged at intervals, so that the air circulation between the heat exchanger 30 and the turbulence piece 50 can be ensured, and part of air in the heat exchanger 30 can flow between the first turbulence plate 51 and the second turbulence plate 52 through the sealing flange 521 and the end, adjacent to the air inlet 11, of the second heat exchanger 32, so as to ensure that the flow speed of the air flow is reduced under the interference of the turbulence piece 50, the heat exchange duration of the air and the heat exchanger 30 is prolonged, and the temperature of the air flow flowing to the heat exchange fan 40 is more uniform.

As shown in connection with fig. 10, the second spoiler 52 is provided extending horizontally. Specifically, the second spoiler 52 extends between the first heat exchanger 31 and the second heat exchanger 32 along the horizontal direction, so that on one hand, the effect of sealing the upper space between the first heat exchanger 31 and the second heat exchanger 32 by the spoiler 50 can be increased, and the flow of part of the air through the space between the first heat exchanger 31 and the second heat exchanger 32 can be prevented, and on the other hand, the structure of the second spoiler 52 is simple, the production is facilitated, and the flow direction can be changed between the first heat exchanger 31 and the second heat exchanger 32 after the air flows through the spoiler 50, so that the occurrence of turbulence in the heat exchanger 30 and the generation of noise can be prevented, and further, the working performance of the air duct machine 100 can be ensured.

As shown in fig. 9, the included angle between the first spoiler 51 and the second spoiler 52 and the included angle between the first heat exchanger 31 and the second heat exchanger 32 are both α, and α satisfies the relationship: alpha is more than or equal to 40 degrees and less than or equal to 50 degrees. Specifically, since the first spoiler 51 is attached to the first heat exchanger 31, the end of the first spoiler 51 adjacent to the air inlet 11 abuts against the end of the first heat exchanger 31 adjacent to the air inlet 11, and the second spoiler 52 is attached to the side of the second heat exchanger 32 facing the first heat exchanger 31, the end of the second spoiler 52 adjacent to the air inlet 11 abuts against the end of the second heat exchanger 32 adjacent to the air inlet 11, that is: the angle between the first spoiler 51 and the second spoiler 52 needs to be set equal to the angle between the first heat exchanger 31 and the second heat exchanger 32.

Through setting the contained angle between the first spoiler 51 and the second spoiler 52 and the contained angle between the first heat exchanger 31 and the second heat exchanger 32 in a reasonable range, on one hand, the contained angle between the first heat exchanger 31 and the second heat exchanger 32 can be prevented from being too large, so that the space occupied by the heat exchanger 30 is larger, the volume of the air duct machine 100 is increased, and on the other hand, the contained angle between the first heat exchanger 31 and the second heat exchanger 32 can be prevented from being too small, so that the air volume of indoor air passing through the first heat exchanger 31 and the second heat exchanger 32 is reduced under the driving of the heat exchange fan 40, the heat exchange performance is lower, and therefore, the structural design of the heat exchanger 30 and even the air duct machine 100 can be further optimized, and the balance between the volume and the working performance of the air duct machine 100 is realized.

As shown in fig. 3, 6, 7, 8 and 10, the length directions of the first heat exchanger 31 and the second heat exchanger 32 are set to be the front-rear direction, the lengths of the first heat exchanger 31 and the second heat exchanger 32 are the same, the lengths of the first heat exchanger 31 and the second heat exchanger 32 are both L2, the lengths of the first spoiler 51 and the second spoiler 52 in the front-rear direction are the same, the lengths of the first spoiler 51 and the second spoiler 52 in the front-rear direction are both L1, and L1 and L2 satisfy the relation: l1=l2, so configured, the first spoiler 51 can completely block the area of the first heat exchanger 31 near the top in the front-rear direction, and the second spoiler 52 can reliably seal and block the area of the heat exchanger 30 near the top in the front-rear direction, thereby preventing a small amount of wind from flowing from the position of the heat exchanger 30 near the top but not sealed and blocked by the spoiler 50, improving the uniformity of the temperature of the heat exchange air flow, further more reliably preventing the generation of condensation, and improving the working safety of the air duct machine 100.

As shown in fig. 3 and 9, the interval direction of the air inlet 11 and the air outlet 12 is set to be the vertical direction, the vertical plane extending in the front-rear direction is set to be the reference plane, the height of the projection of the side of the first heat exchanger 31 toward the second heat exchanger 32 on the reference plane and the height of the projection of the side of the second heat exchanger 32 toward the first heat exchanger 31 on the reference plane are both h1, the height of the projection of the spoiler 50 on the reference plane is h2, and the h1 and h2 satisfy the relation: 1/4 < h2/h1 < 1/2.

Specifically, the interval direction of the air inlet 11 and the air outlet 12 is set to be the vertical direction, and the vertical plane extending in the front-rear direction is set to be the reference plane, by setting the ratio between the height of the projection of the spoiler 50 on the reference plane and the height of the projection of the side of the first heat exchanger 31 facing the second heat exchanger 32 on the reference plane, and the ratio between the height of the projection of the spoiler 50 on the reference plane and the height of the projection of the side of the second heat exchanger 32 facing the first heat exchanger 31 on the reference plane, in this way, on one hand, the sealing shielding area of the spoiler 50 on the top of the heat exchanger 30 can be prevented from being small, the slowing down of the flow velocity of the gas and the guiding effect on the flow direction of the air can be caused to be lower, the heat exchange between the gas and the heat exchanger 30 is not sufficiently uniform, and the generation of condensation can not be avoided, and on the other hand, the structural design of the spoiler 50 can be optimized, the balance between the condensation preventing performance of the air duct 100 and the heat exchange performance of the air duct 100 can be realized.

The cross section of the spoiler 50 and the heat exchanger 30 may be isosceles triangle, that is: the projection height of the first spoiler 51 on the reference plane is h2, the second spoiler 52 is horizontally arranged, and the cross section of the spoiler 50 may not be an isosceles triangle, namely: the second spoiler 52 is disposed obliquely, and is not particularly limited herein. Preferably, the cross section formed by the spoiler 50 and the heat exchanger 30 together is an isosceles triangle, so that the first spoiler 51 can be tightly attached to one of the first heat exchanger 31 and the second heat exchanger 32, and the sealing flange 521 can be tightly attached to one of the first heat exchanger 31 and the second heat exchanger 32, so that the size of the shielding area of the spoiler 50 to the heat exchanger 30 is set in a reasonable range, and the condensation preventing effect of the air duct machine 100 is further improved.

As shown in fig. 3, 4, 6 and 8, the air duct machine 100 may further include two sealing cover plates 60, where the two sealing cover plates 60 are respectively covered and sealed on the front and rear sides of the heat exchanger 30, at least one end of the second spoiler 52 in the front and rear directions is provided with a fixing plate 522, and the fixing plate 522 is attached to and connected with the sealing cover plates 60.

Specifically, in the direction extending from the air inlet 11 to the air outlet 12, the first heat exchanger 31 and the second heat exchanger 32 are gradually far away, and by arranging two sealing cover plates 60, the two sealing cover plates 60 are respectively covered and arranged on the front side and the rear side of the heat exchanger 30 in a sealing manner, so that the two sealing cover plates 60 can correspondingly seal the gaps of the first heat exchanger 31 and the second heat exchanger 32 on the front side and the rear side, and in the heat exchange process of indoor air and the heat exchanger 30, heat exchange airflow can be prevented from leaking from the gaps of the first heat exchanger 31 and the second heat exchanger 32 on the front side and the rear side, and further, the heat exchange airflow can be ensured to flow in the heat exchanger 30 all the time, and the working reliability of the air pipe machine 100 is ensured.

Further, a fixing plate 522 may be disposed at least one end of the second spoiler 52 in the front-rear direction, and the fixing plate 522 is attached to the sealing cover plate 60, so that the fixing plate 522 is fixedly connected to the sealing cover plate 60, and thus, the installation of the spoiler 50 between the first heat exchanger 31 and the second heat exchanger 32 may be achieved, the stability and reliability of the installation of the spoiler 50 between the first heat exchanger 31 and the second heat exchanger 32 may be ensured, and no additional auxiliary installation structure is required, and the structural design of the air duct machine 100 may be simplified.

In addition, unlike the fixing plate 522 arranged at least one end of the first spoiler 51, the fixing plate 522 is arranged at least one end of the second spoiler 52 in the front-rear direction, so that the stress of the spoiler 50 is more uniform, the stability and reliability of the installation and arrangement of the spoiler 50 can be further improved, the normal operation of the spoiler 50 is ensured, and the working performance of the air duct machine 100 is improved.

In some embodiments of the present utility model, as shown in fig. 6, 9, 10 and 11, the sealing cover plate 60 is provided with a first clamping portion 61, and the fixing plate 522 is provided with a second clamping portion 5221, and the first clamping portion 61 and the second clamping portion 5221 are in clamping fit. Specifically, by providing the first clamping portion 61 on the sealing cover plate 60 and providing the second clamping portion 5221 on the fixing plate 522, when the spoiler 50 is disposed between the first heat exchanger 31 and the second heat exchanger 32 in the vertical direction, the first clamping portion 61 and the second clamping portion 5221 may gradually approach each other and finally be clamped and matched, so that the connection between the sealing cover plate 60 and the fixing plate 522 may be realized only by the clamping and matching between the first clamping portion 61 and the second clamping portion 5221, the connection between the sealing cover plate 60 and the fixing plate 522 may be more simple and convenient, the assembly efficiency between the sealing cover plate 60 and the fixing plate 522 may be improved, and the fastening members 53 may be prevented from penetrating the fixing plate 522 and the sealing cover plate 60, and the number of parts may be reduced.

Further, one of the first clamping portion 61 and the second clamping portion 5221 is a clamping hook, and the other is a clamping groove, and the clamping groove is in clamping fit with the clamping hook.
