Description

Technical Field

[0001] The invention relates to the technical field of air coolers, and in particular to an air cooler. Background Art

[0002] The air cooler is a mild cooling device, which mainly realizes air cooling by absorbing heat during the evaporation process of water. Traditional air coolers usually include a water tank, a water pump, an air duct, a fan arranged in the air duct, and a water curtain. Traditional air coolers are usually single-tank air coolers. The water tank is arranged below the water curtain. The water pump pumps the water in the water tank to the top of the water curtain, so that part of the water on the water curtain is evaporated, making the air at the water curtain cooler. The fan blows the airflow passing through the water curtain to the air outlet of the air duct through the air inlet of the air duct, so that the blown air is cooler and more comfortable to achieve the effect of air cooling.

[0003] However, the end face of the air outlet of the traditional air duct is usually a plane perpendicular to the air outlet direction or a plane parallel to the plate surface of the outer shell corresponding to the air outlet. Therefore, most of the wind blown out from the air outlet is concentrated in the area corresponding to the air outlet, so that the blown wind is mostly concentrated in the local area, and only a small part of the wind is blown out around the air outlet. The air outlet range is small and the air supply distances at different locations are uneven. Summary of the invention

[0004] The main purpose of the present invention is to provide an air cooler, aiming to improve the problem of uneven air output.

[0005] To achieve the above-mentioned purpose, the air cooler proposed in the present invention includes a shell and an air duct; the shell has an air outlet; the air duct is arranged in the shell, and the air duct has an air supply port corresponding to the air outlet and connected, and an extension plate is provided at the air supply port, one end of the extension plate is connected to the inner wall of the air supply port, and the other end extends in a direction away from the center of the air supply port and close to the air outlet.

[0006] Optionally, the shell also has an air inlet connected to the air duct, the air duct is arranged on a side of the shell away from the air inlet, the center line of the air inlet is perpendicular to the center line of the air supply outlet, and the extension plate is connected to the inner wall of the air supply outlet close to the air inlet.

[0007] Optionally, the air duct includes a first air duct and a second air duct that are independent of each other, the first air duct and the second air duct both have the extension plate, and the air supply port of the first air duct and the air supply port of the second air duct both correspond to the air outlet.

[0008] Optionally, the first air duct and the second air duct are arranged at the air inlet in a mirror-symmetrical manner.

[0009] Optionally, the first air duct and the second air duct are detachably connected.

[0010] Optionally, the first air duct is snap-connected to the second air duct.

[0011] Optionally, a water curtain is further provided in the shell, and the water curtain is arranged corresponding to the air inlet and is arranged on a side of the air duct facing the air inlet.

[0012] Optionally, an evaporator is further provided in the shell, and the evaporator is provided between the water curtain and the air duct.

[0013] Optionally, a plurality of air guide plates are installed at the air outlet, and the air guide plates are rotatably connected to the shell.

[0014] Optionally, the air guide plate includes a first air guide plate and a second air guide plate which are perpendicular to each other, and the first air guide plate and the second air guide plate are both rotatably connected to the shell.

[0015] The technical solution of the present invention is to provide an extension plate at the air supply outlet, with one end of the extension plate connected to the inner wall of the air supply outlet, and the other end extending in a direction away from the center of the air supply outlet and close to the air outlet, so that a part of the wind delivered from the air supply outlet is blown out vertically at the air supply outlet, and the other part is blown between the extension plate and the air outlet along the extension direction of the extension plate; at the same time, since the other end of the extension plate extends in a direction away from the center of the air supply outlet and close to the air outlet, the farther the extension plate is from the air supply outlet, the shorter the distance between the extension plate and the air outlet, and thus, under the premise of the same air volume, the farther the extension plate is from the air supply outlet, the easier the air is compressed, which leads to a greater air outlet pressure at this location, thereby increasing the air outlet pressure at this location, so that long-distance air supply can be achieved at this location, thereby ensuring a relatively uniform air outlet effect at all locations of the air outlet.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] The invention provides a cooling fan.

[0032] In the embodiments of the present invention, please refer to Figures 1 to 5 The air cooler includes a shell 100 and an air duct 200; the shell 100 has an air outlet 120; the air duct 200 is arranged in the shell 100, and the air duct 200 has an air supply port 201 corresponding to and connected with the air outlet 120, and an extension plate 202 is provided at the air supply port 201, one end of the extension plate 202 is connected to the inner wall of the air supply port 201, and the other end extends in a direction away from the center of the air supply port 201 and close to the air outlet 120.

[0033] The air cooler can draw external wind into the air inlet 110, and then pass through the air duct 200, and then be sent to the air outlet 120 of the air cooler housing 100 through the air supply port 201 of the air duct 200, and finally blow out the cold air through the air outlet 120 of the housing 100. It can be understood that the air supply port 201 of the air duct 200 has a certain size, and when the wind in the air duct 200 is sent out through the air supply port 201, most of the wind will be concentrated at the air supply port 201 and sent out in a direction perpendicular to the air supply port 201; and only a small part of the wind will be blown around the air supply port 201. In the technical solution of the present invention, the structure near the air supply port 201 is changed, that is, an extension plate 202 is provided, one end of the extension plate 202 is connected to the inner wall of the air supply port 201, and the other end extends in a direction away from the center of the air supply port 201 and close to the air outlet 120 (that is, the extension plate 202 is arranged at an acute angle to the air supply direction of the air supply port 201, and the end of the extension plate 202 that is not connected to the inner wall of the air supply port 201 does not block the air supply port 201). On the one hand, the extension plate 202 can guide the airflow, so that a part of the airflow flows along the extension plate 202 and is sent from the extension plate 202 to the air outlet 120. On the other hand, the air volume decreases from the direction close to the center of the air outlet 201 to the direction away from the center of the air outlet 201; and the other end of the extension plate 202 extends in the direction away from the center of the air outlet 201 and close to the air outlet 120, so that the distance between the extension plate 202 and the air outlet 120 becomes closer and closer from the direction close to the center of the air outlet 201 to the direction away from the center of the air outlet 201, and the airflow is more and more easily squeezed, so that the airflow has a greater outlet pressure when it is blown out at the place where the extension plate 202 is far away from the air outlet 201, so that the air supply effect at a longer distance can be achieved, and the effect of uniform air outlet distance at various places of the air outlet 120 is achieved as a whole. Specifically, the plate surface of the extension plate 202 can be a plane or a curved surface. The shape of the air outlet 201 can be rectangular, circular or other shapes. Similarly, the shape of the air outlet 120 can also be rectangular, circular or other shapes. The air supply port 201 may be located inside the housing 100, that is, the airflow first passes through the air supply port 201 and then passes through the air outlet 120 of the housing 100; or, the air supply port 201 may also be arranged to overlap with the air outlet 120, that is, the airflow passes through the air supply port 201 and also passes through the air outlet 120. It is understandable that in the technical solution of the present invention, a fan will be provided in the air duct 200 so as to suck the external wind into the housing 100 and discharge it through the air duct 200. Specifically, the fan may be a cross-flow fan or an axial flow fan. Depending on the type of fan, the center line of the air supply port 201 and the center line of the air inlet 110 may be located on the same straight line, or they may be arranged perpendicular to each other.

[0034] The technical solution of the present invention is to set an extension plate 202 at the air supply outlet 201, and one end of the extension plate 202 is connected to the inner wall of the air supply outlet 201, and the other end extends in a direction away from the center of the air supply outlet 201 and close to the air outlet 120, so that a part of the wind delivered from the air supply outlet 201 is blown out vertically from the air supply outlet 201, and the other part is blown between the extension plate 202 and the air outlet 120 along the extension direction of the extension plate 202; at the same time, since the other end of the extension plate 202 extends in a direction away from the center of the air supply outlet 201 and close to the air outlet 120, the farther the extension plate 202 is from the air supply outlet 201, the shorter the distance between the extension plate 202 and the air outlet 120, and then, under the premise of the same air volume, the farther the extension plate 202 is from the air supply outlet 201, the easier the air is compressed, which leads to a greater air outlet pressure at this place, thereby increasing the air outlet pressure here, so that long-distance air supply can also be achieved there, and the overall effect of relatively uniform air outlet at various places of the air outlet 120 is guaranteed.

[0035] Further, please refer to Figures 1 to 3 The shell 100 also has an air inlet 110 connected to the air duct 200, the center line of the air inlet 110 is perpendicular to the center line of the air supply port 201, the air duct 200 is arranged on a side of the shell 100 away from the air inlet 110, and the extension plate 202 is connected to the inner wall of the air supply port 201 close to the air inlet 110.

[0036] In order to make the wind blown out of the air outlet 120 cooler, the air cooler has a heat exchange device, which is usually arranged corresponding to the air inlet 110 and arranged between the air duct 200 and the air inlet 110, so that when the external wind is sucked in through the air inlet 110, it will be heat exchanged through the heat exchange device, and the gas after heat exchange will be blown to the air outlet 120 of the shell 100 through the air supply port 201 of the air duct 200, and then blown out from the air outlet 120; therefore, the air duct 200 and the side of the shell 100 where the air inlet 110 is provided need to have an installation space for installing the heat exchange device. In this embodiment, the air duct 200 is arranged on the side of the shell 100 away from the air inlet 110, so that an installation space is formed between the air duct 200 and the side of the shell 100 where the air inlet 110 is provided, so as to install the heat exchange device. On this basis, it can be understood that the air supply outlet 201 of the air duct 200 will be closer to the side of the shell 100 away from the air inlet 110. By connecting the extension plate 202 to the inner wall of the air supply outlet 201 close to the air inlet 110, the air outlet range can be expanded to the side of the shell 100 close to the air inlet 110, thereby achieving a better air outlet effect.

[0037] Specifically, Figure 3 As shown, in order to achieve a heat exchange effect, in this embodiment, a water curtain 400 is further provided in the housing 100 . The water curtain 400 is provided corresponding to the air inlet 110 and is provided on a side of the air duct 200 facing the air inlet 110 .

[0038] By arranging the water curtain 400 corresponding to the air inlet 110, the external airflow passes through the air inlet 110 and then passes through the water curtain 400. When the airflow passes through the water curtain 400, it exchanges heat with the water curtain 400 (in the present invention, the water curtain 400 evaporates and absorbs heat), thereby achieving the effect of regulating the airflow temperature. It can be understood that in order to achieve the effect of cooling the external air and blowing out cold air from the air outlet 120, the water on the water curtain 400 in this embodiment can be water with a temperature lower than that of the external air.

[0039] Please refer to Figure 3 and Figure 5 In order to receive the water left on the water curtain 400, a water tank 500 connected to the housing 100 is provided below the water curtain 400 in the technical solution of the present invention. Furthermore, in order to enable the water falling into the water tank 500 to be recycled, a water pump may be provided in the water tank 500, and the water pump is connected to a water pipe, which extends to the top of the water curtain 400, so that when the water pump is working, the water in the water tank 500 can be pumped up and pumped to the top of the water curtain 400 through the water pipe, and then flows down through the water curtain 400 again under the action of gravity.

[0040] In order to cool the water pumped from the water tank 500 to the top of the water curtain 400, the water tank 500 in the technical solution of the present invention may include a first water tank 510 and a second water tank 520, wherein the first water tank 510 is provided with the above-mentioned water pump, and the second water tank 520 is provided above the first water tank 510. The water curtain 400 includes a first sub-water curtain 410 and a second sub-water curtain 420, wherein the first sub-water curtain 410 is provided above the second water tank 520, and the second sub-water curtain 420 is provided between the second water tank 520 and the first water tank 510, and the water pipe connected to the water pump passes through the second sub-water curtain 420 and extends to the top of the first sub-water curtain 410, so that when the water in the water pipe is pumped to the top of the first sub-water curtain 410, the water is firstly heat-exchanged by the first sub-water curtain 410 and the air that has exchanged heat with the first sub-water curtain 410, thereby ensuring that the water pumped to the top of the first sub-water curtain 410 is relatively cold, and further ensuring that the wind blown out of the air outlet 120 is relatively cool.

[0041] Furthermore, if Figure 3 As shown, an evaporator 600 is further disposed in the housing 100 , and the evaporator 600 is disposed between the water curtain 400 and the air duct 200 .

[0042] By arranging the evaporator 600 between the water curtain 400 and the air duct 200, the airflow is cooled once after passing through the water curtain 400, and then cooled twice after passing through the evaporator 600, and finally the cooled airflow is sent out through the air duct 200. Such an arrangement can improve the cooling effect of the air cooler.

[0043] In this embodiment, please refer to Figures 1 to 3The air duct 200 includes a first air duct 210 and a second air duct 220 which are independent of each other. The first air duct 210 and the second air duct 220 both have an extension plate 202 , and the air supply port 201 of the first air duct 210 and the air supply port 201 of the second air duct 220 both correspond to the air outlet 120 .

[0044] In this embodiment, the air supply ports 201 of the first air duct 210 and the second air duct 220 both correspond to the air outlet 120, so that the fans in the first air duct 210 and the fans in the second air duct 220, after sucking in the air from the air inlet 110, are rectified in their respective air ducts 200 and converge at the air supply port 201, and are blown out from the air outlet 120 at the same time after converging. In addition, it can be understood that, under the premise that the size of the air inlet 110 remains unchanged, if one fan is used to suck in the external airflow and rectify it in the air duct 200, then the rectification pressure is relatively large, so that a relatively large noise is generated in the air duct 200; and under the premise that the size of the air inlet 110 remains unchanged, by setting two air ducts 200, that is, setting two fans, the power required for each fan to work can be relatively small, thereby reducing the rectification pressure of each fan, which can reduce the noise generated during rectification on the one hand, and increase the service life of the fan on the other hand. Of course, in other embodiments, three, four or more air ducts 200 may be provided. In the present invention, two air ducts 200 are preferably provided, so that the number of parts installed in the housing 100 can be reduced and the manufacturing cost can be reduced on the basis of reducing the rectified pressure to reduce noise. In addition, the more the number of air ducts 200 is, the more difficult it is to converge the airflows in the multiple air ducts 200 through the air outlet 201.

[0045] For details, please refer to Figures 1 to 3 The first air duct 210 and the second air duct 220 are arranged at the air inlet 110 in a mirror-symmetrical manner.

[0046] Such an arrangement ensures that the first air duct 210 and the second air duct 220 can be stacked and integrated together, thereby achieving the effect of integrating two small air supply outlets 201 into a large air supply outlet 201 .

[0047] Furthermore, in order to facilitate assembly and disassembly, in this embodiment, the first air duct 210 and the second air duct 220 are detachably connected.

[0048] With such arrangement, when one of the air ducts 200 is damaged, it is advantageous to replace only one of the air ducts 200 without replacing the entirety of the first air duct 210 and the second air duct 220 , thereby saving replacement costs and facilitating the installation of the air duct 200 in the housing 100 .

[0049] Further, please refer to Figure 4 , Figure 7 and Figure 8In order to ensure the stability and convenience of the installation of the first air duct 210 and the second air duct 220, the first air duct 210 and the second air duct 220 can be connected by screw connection, flange connection or snap connection. In this embodiment, the first air duct 210 and the second air duct 220 can be optionally snap-connected. For example, one of the first air duct 210 and the second air duct 220 is provided with a snap hole 211, and the other is provided with a snap 221. Specifically, the air duct 200 has an air duct 200 wall, wherein the air duct 200 wall of one air duct 200 is provided with a snap hole 211 facing the end face of the other air duct 200, and the air duct 200 wall of the other air duct 200 is correspondingly convexly provided with a snap 221, and the snap 221 is snapped into the snap hole 211 to achieve the effect of the first air duct 210 and the second air duct 220 snap connection 221. In this way, the efficiency of the connection between the first air duct 210 and the second air duct 220 can be improved.

[0050] Please refer to Figures 3 to 5 In order to adjust the direction of the airflow delivered from the air outlet 201 , a plurality of air guide plates 300 are installed at the air outlet 120 , and the air guide plates 300 are rotatably connected to the housing 100 .

[0051] The wind deflector 300 is rotatably connected to the housing 100, so that the user can adjust the rotation angle of the wind deflector 300, thereby adjusting the wind volume and wind direction blown out from the air outlet 120. Specifically, the wind deflector 300 can be one, two, three or more.

[0052] Specifically, Figure 5 As shown, the air guide plate 300 includes a first air guide plate 310 and a second air guide plate 320 that are perpendicular to each other, and the first air guide plate 310 and the second air guide plate 320 are both rotatably connected to the housing 100 .

[0053] By setting the first air guide plate 310 and the second air guide plate 320 perpendicular to each other, the user can adjust the angle of the air guide plate 300 in the front, back, left, right, or up, down, left, and right directions, thereby more flexibly adjusting the air volume and wind direction of the air outlet. For example, when the air outlet 120 is open toward the front or side, one of the first air guide plate 310 and the second air guide plate 320 can extend in the vertical direction, and the other can extend in the horizontal direction, so that the effect of adjusting the angle of the air guide plate 300 in the up, down, left, and right directions can be achieved. When the air outlet 120 is open toward the top, the first air guide plate 310 and the second air guide plate 320 can both extend in the horizontal direction, but it is only necessary to ensure that the first air guide plate 310 and the second air guide plate 320 are perpendicular to each other, so that the effect of adjusting the angle of the air guide plate 300 in the front, back, left, and right directions can be achieved.

[0054] Of course, the first air guide plate 310 and the second air guide plate 320 may not be arranged vertically, but may have a certain angle, and the air volume and wind direction of the air outlet may also be adjusted more flexibly. In this embodiment, the first air guide plate 310 and the second air guide plate 320 are arranged vertically, which can maximize the adjustment range of the air outlet direction. Specifically, the first air guide plate 310 and the second air guide plate 320 may each be provided with a plurality of them.

[0055] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
