Description

Technical Field

[0001] The present disclosure relates to the technical field of air conditioning, and in particular to a rainproof structure and an air conditioner. Background Art

[0002] When the fresh air air conditioner sucks in fresh air from the air inlet of the fresh air duct, it also sucks in rainwater around the air inlet, causing rainwater to accumulate in the indoor unit. When too much rainwater accumulates, during the operation of the fresh air air conditioner, rainwater will flow out from the assembly gap of the indoor unit and drip into the room, thus affecting the comfort of the whole machine and the usability of the user.

[0003] In order to avoid the occurrence of this phenomenon, the existing technical solutions are mainly to set an air inlet with an opening facing downward, or to install a rain cap with an air inlet with an opening facing downward; but when the fresh air air conditioner is in a high wind speed working state, rainwater flowing along the fresh air duct or the outer wall of the rain cap to the air inlet will still be sucked into the indoor unit.

[0039] Embodiment 1:

[0040] like Figure 1 The rainproof structure 2 shown is arranged at the air inlet 10 of the fresh air duct 1 of the air conditioner and opens downward. The rainproof structure 2 includes:

[0041] The guide portion 20 includes a first end portion 201 disposed around the air inlet 10 and a second end portion 202 that is horizontally away from the air inlet 10, so as to guide rainwater flowing around the air inlet 10 from the first end portion 201 to the second end portion 202;

[0042] The water outlet 21 is disposed at the second end portion 202 to discharge rainwater at the second end portion 202 .

[0043] Among them, when the rainproof structure 2 is not provided, the air inlet 10 with the opening facing downward can prevent most of the rainwater from being sucked into the main body of the device, but the rainwater flowing along the outer wall of the fresh air duct 1 to the vicinity of the air inlet 10 will still be sucked into the main body of the device under high wind speed conditions. By providing the rainproof structure 2 around the air inlet 10, the rainwater flowing along the outer wall of the fresh air duct 1 to the vicinity of the air inlet 10 can be guided by the guide part 20 to the second end 202 far from the air inlet 10, and flows out from the water outlet 21 provided at the second end 202 to reduce the suction force of the air conditioner on the rainwater, thereby preventing the rainwater from being sucked into the air inlet 10 by the air conditioner, reducing the hidden danger of dripping of the indoor unit, and improving the comfort and user usability of the whole machine.

[0044] In the above embodiment, if Figure 1 , Figure 7 and Figure 8 As shown, the air inlet 10 is circular in shape. The distance between the water outlet 21 and the center of the air inlet 10 is about twice the radius of the air inlet 10. This greatly reduces the suction force on the rainwater discharged from the water outlet 21, thereby preventing the rainwater from being sucked into the air conditioner.

[0045] It should be noted that the shape of the air inlet 10 includes but is not limited to polygonal, circular, non-circular or irregular shapes, and the present disclosure is not limited thereto.

[0046] In some embodiments, Figure 1 As shown, the fresh air duct 1 also includes a rainproof cap 12, and the rainproof cap 12 has an air inlet 10 opening downward. The rainproof structure 2 is welded and fixed to the outer wall of the rainproof cap 12. The rainproof structure 2 can be a plate-like structure, a block-like structure or other structures. The present disclosure is not limited to this.

[0047] It should be noted that, in other embodiments, the rainproof structure 2 may also be directly welded and fixed to the air inlet 10 of the fresh air duct 1 without providing a rainproof cap 12 .

[0048] In the above embodiments, the rainproof structure 2 may be a circle, a polygon, or an irregular shape including straight edges and / or curved edges, and the present disclosure is not limited thereto. Figure 1 , 2 As shown in Figures 5 and 6, the rainproof structure 2 may include a straight end face formed on one side of the circle. The end face is located on one side of the fresh air duct 1. The end face is an adaptive cutout made in consideration of the fact that the rainproof structure 2 is too close to the wall, and the end face can play a supporting role when it is close to the wall, thereby enhancing the reliability of the fresh air duct fixation.

[0049] In some embodiments, the guide portion 20 includes a guide surface 203 connected to the outer side wall of the fresh air duct 1, the inner edge of the guide surface 203 connected to the outer side wall of the fresh air duct 1 forms a first end 201, and the outer edge of the guide surface 203 arranged opposite to the inner edge forms a second end 202. In this way, when rainwater flows from the outer side wall of the rain cap 12 to the inner edge of the guide surface 203, i.e., the first end 201, the rainwater will gradually spread to the outer edge of the guide surface 203, i.e., the second end 202, and then be discharged from the water outlet 21, thereby preventing rainwater from directly flowing from the outer side wall of the rain cap 12 to the air inlet 10.

[0050] It should be noted that the guide surface 203 can be a horizontal plane, or can be gradually inclined downward or upward in the direction from the first end 201 to the second end 202, and the present disclosure is not limited to this.

[0051] In some embodiments, Figure 1 As shown, the horizontal distance between the water outlet section 210 of the water outlet 21 and the edge of the air inlet 10 is greater than or equal to 10 mm. The rainproof structure 2 includes a first side wall 24 located at one end of the guide portion 20. The first side wall 24 forms the water outlet section 210 of the water outlet 21.

[0052] In this way, the horizontal distance between the rainwater discharged from the water outlet 21 and the edge of the air inlet 10 is at least 10 mm, thereby effectively reducing the suction force on it, thereby preventing the rainwater from being sucked into the air conditioner. In addition, the first side wall 24 forms at least part of the water outlet 21, which has a simple structure and is easy to form.

[0053] Embodiment 2:

[0054] The difference between this embodiment and the first embodiment is that the rainproof structure 2 in this embodiment further includes a first water retaining portion 22 .

[0055] In some embodiments, Figure 2As shown, the rainproof structure 2 includes a first water retaining portion 22 arranged around the second end portion 202, and the first water retaining portion 22 is located on the guide surface 203 and protrudes from the guide surface 203. A receiving space is thus enclosed, so that rainwater flowing along the outer wall of the fresh air duct 1 to the guide portion 20 can be gathered in the receiving space, and then the rainwater can form larger raindrops or gather into a stream when discharged from the water outlet 21, so as to avoid the formation of small raindrops or rain mist around the air inlet 10.

[0056] In the above embodiment, the height of the first water retaining portion 22 protruding from the guide surface 203 is not less than 5 mm and not more than 30 mm, so that the first water retaining portion 22 can not only collect rainwater but also save costs.

[0057] In some embodiments, the water outlet 21 includes a water outlet 211 connected to the second end 202 to collect rainwater at the second end 202 into a beam and discharge it, thereby preventing rainwater from being sucked into the air inlet 10 by the air conditioner by increasing its own weight.

[0058] The water outlet portion 21 may further include a plurality of water outlet nozzles 211 connected to the second end portion 202 and distributed circumferentially along the second end portion 202 .

[0059] In the above embodiment, if Figure 6 As shown, the water outlet 211 includes a water outlet channel 212 connected to the second end 202. The bottom surface of the water outlet channel 212 forms an angle greater than or equal to 90° and less than or equal to 180° with the horizontal plane. In this way, when rainwater is discharged along the water outlet channel 212, the gravity acceleration can increase its discharge speed, thereby increasing the momentum of the rainwater itself, thereby avoiding being sucked in from the air inlet 10 by the air conditioner. At the same time, the rainwater is discharged in a direction away from the air inlet 10, which can also avoid being sucked in from the air inlet 10 by the air conditioner.

[0060] In the above embodiment, the water outlet channel 212 includes a water inlet and a water outlet. The water inlet is arranged at the first water retaining portion 22 , and the water outlet is the water outlet cross section 210 of the water outlet portion 21 .

[0061] Embodiment three:

[0062] The difference between this embodiment and the first embodiment is that the rainproof structure 2 in this embodiment further includes a second water retaining portion 25 .

[0063] In some embodiments, Figure 3 As shown, the rainproof structure 2 includes a first lower surface 23 disposed opposite to the guide surface 203. The rainproof structure 2 includes a second water retaining portion 25 disposed around the edge of the first lower surface 23. The second water retaining portion 25 is located on the first lower surface 23 and protrudes from the first lower surface 23.

[0064] Among them, when the second water retaining portion 25 is not provided, when rainwater is discharged from the water outlet portion 21, the rainwater will not only be sucked by the air conditioner, but also by the rainproof structure 2 itself, so that the rainwater may adhere to the first lower surface 23 and gradually move toward the direction close to the air inlet 10. By providing the second water retaining portion 25, this situation can be avoided.

[0065] In the above embodiment, the height of the second water retaining portion 25 protruding from the first lower surface 23 is not less than 2 mm and not more than 30 mm, so that the second water retaining portion 25 can not only prevent rainwater from being sucked into the air inlet 10 along the first lower surface 23, but also save costs.

[0066] Embodiment 4:

[0067] The difference between this embodiment and the first embodiment is that the air guide portion 20 in this embodiment gradually tilts downward in a direction away from the air inlet 10 .

[0068] In some embodiments, Figure 4 As shown, an angle B is formed between the guide surface 203 and the horizontal plane. The angle B is greater than or equal to 0° and less than or equal to 30°, so that the speed of rainwater flowing around the air inlet 10 from the first end 201 to the second end 202 is accelerated, thereby preventing the rainwater from being sucked into the air inlet 10.

[0069] In the above embodiment, an angle C is formed between the first lower surface 23 and the horizontal plane. The angle C is greater than or equal to 0° and less than or equal to 30°, so as to prevent the outer edge of the first lower surface 23 from forming another air inlet 10 of the fresh air duct 1, thereby making the rainproof structure 2 lose the function of preventing rainwater from being sucked into the air inlet 10.

[0070] Embodiment five:

[0071] The difference between this embodiment and the first embodiment is that the rainproof structure 2 in this embodiment further includes guide ribs 26 .

[0072] In some embodiments, Figure 5 As shown, the guide surface 203 is provided with a plurality of guide ribs 26 , which extend in a direction from the first end 201 to the second end 202 , so as to more accurately guide rainwater flowing around the air inlet 10 from the first end 201 to the second end 202 .

[0073] Embodiment six:

[0074] like Figure 7As shown, this embodiment provides an air conditioner, including an equipment body, a fresh air duct 1 and a rainproof structure 2 in any of the above embodiments. The fresh air duct 1 is connected to the equipment body and includes an air inlet 10 with an opening facing downward. The rainproof structure 2 is arranged around the air inlet 10. Among them, the fresh air duct 1 includes a pipe body 13 and a rainproof cap 12. The rainproof cap 12 is connected to the pipe body 13. The rainproof cap 12 includes an air inlet 10 with an opening facing downward.

[0075] In the above embodiment, the diameter of the air inlet 10 is larger than the diameter of the tube body 13 to increase the air intake volume and air intake efficiency of the fresh air. Of course, in other embodiments, the diameter of the air inlet 10 can also be less than or equal to the diameter of the tube body 13.

[0076] It should be noted that, since the diameter of the air inlet 10 is larger than the diameter of the tube body 13 , the structure of the rain cap 12 itself cannot be directly cast as one piece, but is formed by welding the first body member 120 and the second body member 121 to each other.

[0077] like Figure 8 As shown, it is an optional implementation manner of manufacturing the above-mentioned rainproof structure 2:

[0078] The rainproof structure 2 includes a first rainproof member 27 and a second rainproof member 28. The first body member 120 and the first rainproof member 27 are integrally formed, and the second body member 121 and the second rainproof member 28 are integrally formed.

[0079] Then, the first body member 120 and the second body member 121 are fixed to each other by ultrasonic welding, and the first rainproof member 27 and the second rainproof member 28 are fixed to each other by ultrasonic welding, so as to ensure the sealing of the connection of the rainproof cap 12 and the strength of the structure of the rainproof cap 12 and the rainproof member.

[0080] Another optional implementation of manufacturing the above-mentioned rainproof structure 2 is:

[0081] The first body member 120 and the second body member 121 are fixed to each other by ultrasonic welding to form the rain cap 12. The rain cap structure 2 is then fixed to the rain cap 12 by ultrasonic welding. Thus, the sealing of the connection of the rain cap 12 can be ensured, and the strength of the structure of the rain cap 12 and the rain cap structure 2 can be ensured.

[0082] Those skilled in the art will readily come up with other embodiments of the present disclosure after considering the specification and practicing the technical solutions disclosed herein. The present disclosure is intended to cover any variations, uses or adaptations of the present disclosure, which follow the general principles of the present disclosure and include common knowledge or customary technical means in the art that are not disclosed in the present disclosure.
