Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

Referring to FIGS. 1 to 7 , the present application provides an air conditioner, comprising an electric control box 1, a panel 2, a water baffle 3 and a fan 4. The electric control box 1 is connected to the panel 2, the electric control box 1 is provided with an electric control box heat dissipation hole 5, the panel 2 is provided with a panel heat dissipation hole 6, the water baffle 3 is arranged on the side of the panel 2 facing away from the electric control box 1 and corresponds to the position of the panel heat dissipation hole 6, a heat dissipation channel 7 is formed between the water baffle 3 and the panel 2, the fan 4 is arranged on the side of the panel 2 facing away from the electric control box 1, a heat dissipation area is formed between the fan 4 and the panel 2 on the side facing the panel 2, and the heat dissipation port of the heat dissipation channel 7 is connected to the heat dissipation area.

In some embodiments, the electric control box 1 is connected to the enclosure 2, and the electric control box 1 is provided with an electric control box heat dissipation hole 5, which is used to achieve air connectivity between the inside and outside of the electric control box 1, accelerate the heat exchange efficiency between the inside and outside of the electric control box 1, and enable the heat dissipated by the internal components of the electric control box 1 to be promptly conducted to the outside of the electric control box 1 through the electric control box heat dissipation hole 5; the enclosure 2 is provided with an enclosure heat dissipation hole 6, which is used to achieve air connectivity on both sides of the enclosure heat dissipation hole 6, so that the heat conducted from the electric control box 1 can be further conducted out in time. The water retaining plate 3 is arranged on the side of the enclosure 2 facing away from the electric control box 1 and corresponds to the position of the enclosure heat dissipation hole 6. For example, along the direction perpendicular to the enclosure 2, at least part of the water retaining plate 3 blocks the enclosure heat dissipation hole 6, thereby preventing outdoor rainwater or water droplets from passing through the enclosure heat dissipation hole 6. The water retaining plate 3 has a water-blocking effect on the enclosure heat dissipation hole 6, ensuring that outdoor rainwater or water droplets will not enter the electric control box 1 through the enclosure heat dissipation hole 6 and the electric control box heat dissipation hole 5, thereby avoiding the influence of rainwater or water droplets on the normal operation of the internal components of the electric control box 1.

In some embodiments, a heat dissipation channel 7 is formed between the water retaining plate 3 and the enclosure 2, and the fan 4 is arranged on the side of the enclosure 2 facing away from the electric control box 1. A heat dissipation area is formed between the fan 4 and the enclosure 2 on the side facing the enclosure 2. When the fan 4 is working, the heat dissipation area will become a heat dissipation negative pressure area. Referring to the arrow shown near the fan in FIG6, it indicates the flow direction of the air when the fan is working. The heat dissipation negative pressure area formed by the fan 4 can be used to timely inhale the hot air and dissipate it to the outside of the air conditioner through the fan 4. The water retaining plate 3 is located on the side of the enclosure 2 facing the fan 4, and the heat dissipation port of the heat dissipation channel 7 is connected to the heat dissipation area, that is, the heat dissipated by the internal components of the electric control box 1 is conducted to the heat dissipation channel 7 through the electric control box heat dissipation hole 5 and the enclosure heat dissipation hole 6, and then is sucked away by the heat dissipation negative pressure area formed by the fan 4 and dissipated through the fan 4. In other words, a structure is provided for the electric control box 1 that can complete heat dissipation and meet the waterproof requirements at the same time, thereby meeting the performance requirements of the air conditioner in different working conditions and working scenes.

The electric control box in the present application can also be other electrical components with both heat dissipation and waterproofing requirements. At the same time, the air conditioner in the present application can be a window air conditioner, a wall-mounted air conditioner, or a vertical air conditioner. As long as the air conditioner is equipped with electrical components with heat dissipation and waterproofing requirements, the type and model of the air conditioner are not limited.

In some embodiments, on the projection surface perpendicular to the enclosure 2, the projection of the heat dissipation holes 5 of the electric control box is spaced apart from the projection of the heat dissipation holes 6 of the enclosure, that is, the heat dissipation holes 5 of the electric control box and the heat dissipation holes 6 of the enclosure are staggered, so that even if rainwater or water droplets enter the area of the electric control box 1 through the heat dissipation holes 6 of the enclosure, they will not directly enter the electric control box 1 through the heat dissipation holes 5 of the electric control box, thereby further preventing rainwater or water droplets from entering the electric control box 1.

Continuing to refer to FIG. 2, FIG. 3, FIG. 4, FIG. 6 and FIG. 7, the electric control box 1 includes an electric control box body 11 and an electric control box cover 12. It can be understood that the purpose of the electric control box 1 including the electric control box body 11 and the electric control box cover 12 is to facilitate the inspection and replacement of the internal components of the electric control box 1. Of course, the electric control box 1 can also be an integral design. The enclosure 2 includes a front enclosure 21 and a side enclosure 22 connected to the front enclosure 21 in an L shape. The side enclosure 22 is provided with an electric control box accommodating port for accommodating the electric control box body 11 and a plurality of electric control box mounting holes arranged around the electric control box accommodating port. The electric control box body 11 and/or the electric control box cover 12 are provided with connection holes corresponding to the electric control box mounting holes.

In some embodiments, the electric control box body 11 is inserted into the electric control box receiving opening along the side of the side panel 22 away from the front panel 21 and in the direction of the side panel 22 toward the side of the front panel 21, and the connecting hole on the electric control box body 11 is connected with the electric control box mounting hole on the side panel 22 by screws, and the electric control box cover 12 is installed on the electric control box body 11 on the side of the side panel 22 away from the front panel 21, and further, the connecting hole on the electric control box cover 12 can be connected with the electric control box mounting hole on the side panel 22 by screws. The advantage of this installation method is that when it is necessary to inspect and replace the internal components of the electric control box 1, it can be inspected and replaced by only opening the cover plate, without disassembling the side panel 22.

In some embodiments, the electric control box body 11 is installed on the electric control box cover 12, and the electric control box cover 12 is connected to the side panel 22 through the electric control box installation hole. The advantage of this installation method is that it is convenient to disassemble and replace the electric control box 1 as a whole. In some embodiments, the side panel 22 may not have any installation holes, and the electric control box 1 or the electric control box 11 is directly installed on the side panel 22, or the electric control box 1 is directly connected to the front panel 21. It should be noted that in some embodiments In this example, a fixed side panel connected to the front panel 21 in an L shape is provided at the end of the front panel 21 away from the side panel 22 (i.e., the end away from the electronic control box 1). The fixed side panel is used to connect the front panel 21 and will be connected to the air conditioner to enhance the stability of the panel 2.

In some embodiments, as shown in FIG. 7 , the heat dissipation hole 5 of the electric control box includes a first heat dissipation hole 51 disposed on a side wall of the electric control box body 11 close to the front panel 21. The first heat dissipation hole 51 is staggered with the heat dissipation hole 6 of the panel. A gap is reserved between the electric control box body 11 and the front panel 21, and the first heat dissipation hole 51 is connected with the heat dissipation hole 6 of the panel to form a first heat dissipation channel 71. The first heat dissipation channel 71 is connected with the heat dissipation channel 7 through the heat dissipation hole 6 of the panel. When working, the internal gas of the electric control box 1 heated by the operation of the internal components of the electric control box 1 realizes convection heat exchange with the internal gas of the first heat dissipation channel 71 through the first heat dissipation hole 51, and then realizes convection heat exchange between the internal gas of the electric control box 1 and the gas at the heat dissipation channel 7 through the heat dissipation hole 6 of the panel, and accelerates the heat dissipation of the inside of the electric control box 1 through direct heat convection between the gases. In addition, the staggered arrangement of the first heat dissipation hole 51 and the enclosure heat dissipation hole 6 helps to improve the waterproof performance of the electric control box 1. In the most unfavorable case, when outdoor rain or water drops enter the surrounding area of the electric control box 1 enclosed by the enclosure 2 through the enclosure heat dissipation hole 6, the staggered arrangement can prevent rain or water drops from directly entering the electric control box 1 through the first heat dissipation hole 51, thereby preventing water drops from damaging the internal components of the electric control box 1 when the above situation occurs. It should be noted that the arrangement of the first heat dissipation channel 71, on the one hand, helps to dissipate the heat inside the electric control box 1, and on the other hand, can prevent the side wall of the electric control box body 11 close to the front enclosure 21 from directly contacting the front enclosure 21, thereby forming a capillary phenomenon and causing water drops to remain.

Continuing to refer to FIG. 2 , FIG. 6 and FIG. 7 , in some embodiments, the air conditioner includes an air duct volute 41 located on the side of the front panel 21 facing the electric control box 1. In the direction of the side of the electric control box body 11 away from the front panel 21 and the direction of the side of the electric control box body 11 away from the electric control box cover 12, a gap is reserved between the electric control box body 11 and the air duct volute 41 to form a second heat dissipation channel 72. Correspondingly, the electric control box heat dissipation hole 5 also includes a second heat dissipation hole 52 provided on a side wall of the electric control box body 11 away from the front panel 21. The second heat dissipation hole 52 is connected to the enclosure heat dissipation hole 6 through the second heat dissipation channel 72, and the enclosure heat dissipation hole 6 is arranged opposite to the second heat dissipation channel 72. It can be understood that the function of the second heat dissipation hole 52 is to connect the gas inside the electric control box 1 with the gas inside the second heat dissipation channel 72, to achieve convection heat exchange between the gas inside the electric control box 1 and the gas inside the second heat dissipation channel 72, and further enhance the heat dissipation effect of the electric control box 1. Enclosure heat dissipation The beneficial effects of the hole 6 being arranged opposite to the second heat dissipation channel 72 are: on the one hand, the efficiency of convective heat exchange between the gas inside the second heat dissipation channel 72 and the gas in the heat dissipation channel 7 is improved; on the other hand, it avoids the direct impact of outdoor rain or water droplets on the electric control box 1 after passing through the heat dissipation hole 6 of the enclosure under the most unfavorable conditions.

In some embodiments, since the side of the electric control box body 11 away from the front panel 21 is less likely to be invaded by water drops, a heat dissipation port 54 is provided on the side of the electric control box body 11 away from the front panel 21, and the heat dissipation port is located at the lower part of the electric control box body 11, and the second heat dissipation hole 52 is located at the upper part of the electric control box body 11. That is to say, according to the actual working situation, under the condition of meeting the waterproof performance requirements or index requirements, other shapes and numbers of heat dissipation ports can be added to the electric control box body, and this application does not limit this.

Continuing to refer to FIG. 1 and FIG. 6, in some embodiments, the air conditioner includes an air conditioner outer box 8, the electric control box 1, the enclosure 2, the water baffle 3 and the fan 4 are all located in the air conditioner outer box 8, an air inlet channel 9 is formed between the air conditioner outer box 8 and the fan 4, and the water baffle 3 is arranged opposite to the air inlet channel 9. The arrows shown in FIG. 1 indicate the inlet and outlet directions of the air. It can be understood that, due to the wrapping of the air conditioner outer box 8 on the whole air conditioner, rain or water droplets mainly affect the electric control box 1 through the air inlet channel 9, and thus the purpose of setting the water baffle 3 opposite to the air inlet channel 9 is to block rain or water droplets coming from this path.

2, the water baffle 3 includes a water baffle portion 31 facing the air inlet channel 9 and upper and lower connecting portions 32 (i.e., an upper connecting portion and a lower connecting portion) connected to the water baffle portion 31 at a preset angle, and the water baffle 3 is connected to the front panel 21 via the upper and lower connecting portions 32. By providing the upper and lower connecting portions 32, the water baffle 3 protects the heat dissipation holes 6 of the panel in the vertical direction, and further improves the waterproof performance of the electric control box 1.

In some embodiments, the side of the water baffle 3 close to the air-conditioning outer box 8 is squeezed and sealed with the air-conditioning outer box 8 through a soft connection. For example, a soft material such as a sealing rubber pad is provided at the position where the water baffle 3 is squeezed and sealed with the air-conditioning outer box 8 to achieve squeeze sealing. The water baffle 3 is provided with a heat dissipation opening on the side close to the fan 4 to connect the heat dissipation channel 7 with the heat dissipation area. It can be understood that the beneficial effect of the side of the water baffle 3 close to the air-conditioning outer box 8 being squeezed and sealed with the air-conditioning outer box 8 through a soft connection is that through the squeeze sealing between the water baffle 3 and the air-conditioning outer box 8, a complete partition wall is formed in the direction of the water baffle 3 facing the air inlet channel 9, which can effectively block rainwater blown in or sucked in from the air inlet channel 9 from passing through the space between the water baffle 3 and the air-conditioning outer box 8. The gap enters the heat dissipation channel 7 and then enters the electric control box 1. On the other hand, the water baffle 3 is provided with a heat dissipation opening on the side close to the fan 4, which is used to connect the heat dissipation channel 7 with the heat dissipation area, so that the hot air at the heat dissipation channel 7 can be directly dissipated by the fan 4 through the heat dissipation area. With this as the goal, the shape and position of the heat dissipation opening can be adaptively set according to the working conditions of the equipment, and this application does not make specific restrictions. In particular, the heat dissipation opening is opened on the water baffle 3 at a height equivalent to or higher than the height of the heat dissipation hole 6 of the enclosure.

Since the fan 4 needs to take in air from the air inlet channel 9 during operation, based on the air movement trajectory inside the air inlet channel 9, in some embodiments, as shown in Figure 2, the water retaining portion 31 is bent at a preset angle toward the front panel 21 on the side close to the fan 4, and the panel heat dissipation hole 6 is arranged on the upper part of the front panel 21. The water retaining portion 31 narrows in the direction away from the fan 4 at a position lower than the preset height of the lower edge of the panel heat dissipation hole 6.

It should be noted that the advantages of the water retaining portion 31 being bent at a set angle toward the front panel 21 on the side close to the fan 4 are: on the one hand, the air intake efficiency of the air inlet channel 9 is improved, thereby improving the working efficiency and heat exchange efficiency of the fan; on the other hand, the probability of rainwater or water droplets entering the heat dissipation channel 7 is reduced; on the other hand, by bending the water retaining portion 31 at a set angle toward the front panel 21 on the side close to the fan 4, the movement speed of hot air at the heat dissipation opening of the heat dissipation channel 7 is increased, and the Bernoulli effect can be used to greatly accelerate the dissipation rate of hot air in the heat dissipation channel 7. The advantages of the panel heat dissipation hole 6 being arranged at the upper part of the front panel 21 are: on the one hand, the upward movement of hot air can effectively accelerate the dissipation of hot air in the first heat dissipation channel 71 and the second heat dissipation channel 72; on the other hand, the upper arrangement can prevent rainwater from entering the first heat dissipation channel 71 and the second heat dissipation channel 72 through the panel heat dissipation hole 6 in extreme weather. At the same time, the purpose of narrowing the water retaining portion 31 in the direction away from the fan 4 at a position lower than the preset height of the lower edge of the heat dissipation hole 6 of the enclosure is to improve the air intake efficiency and air intake speed of the air inlet channel 9 while ensuring that the hot air emitted from the heat dissipation hole 6 of the enclosure is further dissipated through the heat dissipation channel 7, thereby improving the heat dissipation efficiency of the fan 4, and utilizing the Bernoulli effect to further accelerate the dissipation rate of the hot air in the heat dissipation channel 7.

Of course, according to the actual working conditions and working requirements of the equipment, the angle at which the water retaining portion 31 is bent toward the front panel 21 on the side close to the fan 4, the height at which the panel heat dissipation holes 6 are set on the front panel 21, the height at which the water retaining portion 31 is narrowed, and the narrowing scale of the water retaining portion 31 can be adaptively adjusted, and the present application does not impose any restrictions on this.

Continuing to refer to FIG. 3 , FIG. 6 and FIG. 7 , in some embodiments, a gap is reserved between the air conditioner outer box 8 and the electric control box cover 12 to form a third heat dissipation channel 73, the third heat dissipation channel 73 is connected to the heat dissipation channel 7, and the electric control box heat dissipation hole 5 also includes a third heat dissipation hole 53 provided on the electric control box cover 12, and the third heat dissipation hole 53 is connected to the heat dissipation channel 7 through the third heat dissipation channel 73. It can be understood that the function of the third heat dissipation hole 53 is to connect the gas inside the electric control box 1 with the gas inside the third heat dissipation channel 73, to achieve convection heat exchange between the gas inside the electric control box 1 and the gas inside the third heat dissipation channel 73, and then make the hot air after heat exchange dissipate through the heat dissipation channel 7 formed between the water baffle 3 and the front panel 21, and further enhance the heat dissipation effect of the electric control box 1.

The heat dissipation holes 5 of the electric control box and the heat dissipation holes 6 of the enclosure are both louver heat dissipation holes. The heat dissipation holes 5 of the electric control box are tilted downward in the direction from the inside of the electric control box 1 to the outside of the electric control box 1, and the heat dissipation holes 6 of the enclosure are tilted downward in the direction from the side of the enclosure 2 toward the electric control box 1 to the back of the electric control box 1. It can be understood that the advantage of setting the heat dissipation holes 5 of the electric control box as louver heat dissipation holes and tilting downward is to prevent rainwater or water droplets from entering the electric control box 1 from the upper side, and the purpose of setting the heat dissipation holes 6 of the enclosure as louver heat dissipation holes and tilting downward is to prevent rainwater or water droplets from entering the first heat dissipation channel 71 and the second heat dissipation channel 72 from the upper side. With this as the goal, the shapes and directions of the heat dissipation holes 5 of the electric control box and the heat dissipation holes 6 of the enclosure can be adaptively adjusted according to the working conditions and actual needs of the equipment, and this application does not limit this.

Continuing to refer to FIG. 4 and FIG. 5 , in some embodiments, a wire hole 10 is provided on one side of the electric control box body 11 close to the front panel 21, a sealing rubber block 101 is provided at the wire hole 10, and a waterproof wire pressing cover plate 211 is provided at a position on the front panel 21 directly opposite to the wire hole 10. The sealing rubber block 101 and the waterproof wire pressing cover plate 211 are both arranged downward. It can be understood that the purpose of providing the sealing rubber block 101 at the wire hole 10, providing the waterproof wire pressing cover plate 211 at a position on the front panel 21 directly opposite to the wire hole 10, and the sealing rubber block 101 and the waterproof wire pressing cover plate 211 are both arranged downward is to ensure the waterproof performance requirements of the electric control box 1 while meeting the wiring requirements, with this as the goal, any other waterproof measures and technical means that meet the waterproof requirements can also be adopted at the wire hole 10, and this application does not make specific restrictions on this.

When the air conditioner is working, the components inside the electric control box 1 work to heat the air inside the electric control box 1. A part of the hot air inside the electric control box 1 enters the first heat dissipation channel 71 through the first heat dissipation hole 51, and a part of the hot air enters the second heat dissipation channel 72 through the second heat dissipation hole 52 and the heat dissipation port 54. A part of the air enters the third heat dissipation channel 73 through the third heat dissipation hole 53 and then enters the heat dissipation channel 7. The hot air in the first heat dissipation channel 71 and the second heat dissipation channel 72 enters the heat dissipation channel 7 through the enclosure heat dissipation hole 6. The hot air in the heat dissipation channel 7 passes through the heat dissipation opening on the water baffle 3 and then through the heat dissipation negative pressure area formed by the operation of the fan 4 and is dispersed out of the air conditioner by the fan 4. The rain or water droplets entering from the direction of the air inlet channel 9 are directly blocked by the water baffle 3 on the side of the water baffle 3 facing away from the enclosure heat dissipation hole 6, thereby avoiding the influence of rain or water droplets on the electric control box 1. Therefore, the electric control box 1 meets the performance requirements of waterproofing and heat dissipation at the same time.
