Description

Technical Field

[0001] This invention relates to the field of fan technology, specifically to air duct structure and humidification air outlet equipment. Background Technology

[0002] Traditional air coolers primarily rely on evaporative cooling pads at the air inlet to cool the incoming air. The larger the contact area between the evaporative cooling pad and the air inlet, the stronger the cooling effect. However, most air coolers use short, straight ducts with air intake at one end and exhaust at the other, limiting the space available for the evaporative cooling pad. Therefore, the area covered by the evaporative cooling pad at the air inlet is relatively small, resulting in a less effective cooling effect. Summary of the Invention

[0003] In view of this, the present invention provides an air duct structure and a humidification air outlet device to solve the problem that the area of ​​the wet curtain covering the air inlet and the area of ​​the air inlet are relatively small in the air ducts of related technologies.

[0004] In a first aspect, the present invention provides an air duct structure, including an air duct shell, the air duct shell having a first air inlet, a second air inlet and an air outlet, the first air inlet and the second air inlet being connected to the air outlet, and both the first air inlet and the second air inlet being suitable for being fitted with wet curtains.

[0005] Beneficial effects: The air duct shell has two air inlets and one air outlet. Air enters through both air inlets simultaneously and is finally blown out through the air outlet. Compared with related technologies, the air intake area is doubled, which can increase the air volume. Wet curtains can be installed outside the first and second air inlets, so the area covered by the wet curtains at the air inlets of the air duct can reach the maximum value of 1, thus improving the cooling effect.

[0006] In one alternative embodiment, the duct housing is T-shaped.

[0007] Beneficial effects: The structure of the air duct shell is easy to process. When air is introduced, it enters horizontally from the first and second air inlets on the left and right sides, resulting in low air intake resistance.

[0008] In one optional embodiment, the centers of the first air inlet and the second air inlet are on the same horizontal line, and both the first air inlet and the second air inlet are vertically arranged.

[0009] Beneficial effects: Since both the first and second air inlets are vertically arranged, it is easy to make the air duct shell swing up and down while keeping the wet curtain assembly stationary.

[0010] In one optional embodiment, the duct shell includes a first inlet section, a second inlet section, and an outlet section connected to each other. The first inlet section is provided with a first air inlet, the second inlet section is provided with a second air inlet, and the outlet section is provided with an air outlet. The first inlet section and the outlet section are connected by a smooth curved surface, and the second inlet section and the outlet section are connected by a smooth curved surface.

[0011] Beneficial effects: The first inlet section and the outlet section are connected by a smooth curved surface, and the second inlet section and the outlet section are connected by a smooth curved surface. This can reduce the resistance of air flowing from the first air inlet and the second air inlet to the air outlet, making the air intake smooth and continuous, and having little impact on the wind speed.

[0012] In one alternative embodiment, along the airflow direction, the first inlet section includes a first curved portion that bends toward the air outlet on the side away from the outlet section, and / or the second inlet section includes a second curved portion that bends toward the air outlet on the side away from the outlet section.

[0013] Beneficial effects: Since the first curved section bends towards the air outlet on the side away from the outlet section, and the second curved section bends towards the air outlet on the side away from the outlet section, it can avoid the air intake of the first air inlet and the air intake of the second air inlet from directly colliding and reducing the air volume and wind speed at the air outlet. At the same time, it can reduce the resistance of air flowing from the first air inlet and the second air inlet to the air outlet, making the air intake continuous and smooth, and having little impact on the wind speed.

[0014] In one alternative embodiment, the first inlet section and the second inlet section are symmetrically arranged, and the connection between the first curved portion and the second curved portion is directly opposite the center of the air outlet.

[0015] Beneficial effect: Since the connection between the first and second curved sections is directly opposite the center of the air outlet, the air intake volume of the first and second air inlets can be equal.

[0016] In one optional embodiment, the connection between the first curved portion and the second curved portion is not lower than the lowest position of the first air inlet and the second air inlet.

[0017] Beneficial effects: By ensuring that the connection between the first and second curved sections is not lower than the lowest point of the first and second air inlets, space within the outlet section can be avoided, thus reducing air loss.

[0018] In one optional embodiment, the first air inlet and the second air inlet are provided with rotating mounting parts.

[0019] Beneficial effect: By setting rotating mounting parts at the first and second air inlets, it is easy to realize the up and down swing of the air duct structure.

[0020] Secondly, the present invention also provides a humidifying air outlet device, comprising:

[0021] The aforementioned air duct structure includes fan blades and a main motor that drives the fan blades to rotate.

[0022] The support bracket is provided in two parts, and the air duct structure is rotatably disposed between the two support brackets;

[0023] The evaporative cooling pad assembly is located on the side of the support bracket away from the air duct structure.

[0024] Beneficial effects: The duct shell has two air inlets and one air outlet. Air enters through both inlets simultaneously and exits through the outlet. Compared with related technologies, the air intake area is doubled, increasing the air volume. Support brackets are installed outside both the first and second air inlets. A wet curtain assembly is located on the side of the support brackets facing away from the duct structure, outside the first and second air inlets. This maximizes the area covered by the wet curtain at the air inlets, improving cooling efficiency. Furthermore, the duct structure is rotatably mounted between the two support brackets, allowing for vertical oscillation and, theoretically, 360° vertical oscillation.

[0025] In one alternative embodiment, at least one of the support brackets is fixedly connected to a rotating shaft, and the air duct structure is rotatable relative to the rotating shaft.

[0026] Beneficial effect: The rotating shaft allows the air duct structure to swing up and down stably.

[0027] In one alternative embodiment, the evaporative cooling pad assembly includes an evaporative cooling pad support and an evaporative cooling pad disposed on the evaporative cooling pad support.

[0028] Beneficial effects: The evaporative cooling pad bracket is used to support the installation of evaporative cooling pads. During assembly, the evaporative cooling pad can be installed on the evaporative cooling pad bracket first, and then the evaporative cooling pad bracket can be fixedly installed on the support bracket.

[0029] In one alternative embodiment, the humidifying air outlet device further includes an air inlet screen, which is connected to the support bracket and covers the wet curtain assembly inside it.

[0030] Beneficial effects: The air inlet mesh cover is used to protect the evaporative cooling pad, preventing direct contact between human hands and the pad. The air inlet mesh cover is connected to the support bracket, enclosing both the evaporative cooling pad and its bracket, resulting in a more aesthetically pleasing appearance.

[0031] In one alternative embodiment, the air inlet grille and the support bracket are connected by snap-fit.

[0032] Beneficial effects: The connection between the air inlet mesh cover and the support bracket is simple and convenient. Attached Figure Description

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Traditional air coolers primarily rely on evaporative cooling pads at the air inlet to cool the incoming air. The larger the contact area between the evaporative cooling pad and the air inlet, the stronger the cooling effect. However, most air coolers use short, straight ducts with air intake at one end and exhaust at the other, limiting the space available for the evaporative cooling pad. Therefore, the area covered by the evaporative cooling pad at the air inlet is relatively small, resulting in a less effective cooling effect.

[0050] In addition, since there is water on the wet curtain, electrical safety is a concern. Given that the oscillation function is an essential feature of a fan, the structural design usually avoids the wet curtain from swinging up and down randomly with the head (because when the wet curtain swings up and down, it moves in an arc around the axis of rotation, not vertically up and down; if the wet curtain swings up and down randomly with the head, water will leak out) to avoid water coming into contact with electricity and causing safety hazards.

[0051] The following is combined Figures 1 to 12 The following describes embodiments of the present invention.

[0052] According to embodiments of the present invention, in one aspect, an air duct structure is provided, such as... Figures 1 to 3 As shown, the device includes a duct housing 1, which has a first air inlet 101, a second air inlet 102, and an air outlet 103. The first air inlet 101 and the second air inlet 102 are both connected to the air outlet 103. The first air inlet 101 and the second air inlet 102 are both suitable for installing wet curtains 4.

[0053] In this embodiment, the air duct shell 1 has two air inlets and one air outlet 103. Air enters through the two air inlets simultaneously and is finally blown out through the air outlet 103. Compared with related technologies, the air intake area is doubled, which can increase the air intake volume. Wet curtains 4 can be installed outside the first air inlet 101 and the second air inlet 102. Therefore, the area covered by the wet curtain 4 at the air inlet of the air duct can reach the maximum value of 1, which improves the cooling effect.

[0054] In one embodiment, the duct housing 1 is T-shaped.

[0055] In this embodiment, the structure of the air duct shell 1 is easy to process. When air is introduced, it enters horizontally from the first air inlet 101 and the second air inlet 102 on the left and right sides, resulting in low air intake resistance.

[0056] In one embodiment not shown in the figure, the duct housing 1 is Y-shaped. It should be noted that when the duct housing 1 is Y-shaped, if the first air inlet 101 and the second air inlet 102 are symmetrical and both are vertically arranged, it is also convenient to realize the up and down swinging of the duct housing 1 while keeping the wet curtain assembly stationary.

[0057] In one embodiment, the centers of the first air inlet 101 and the second air inlet 102 are on the same horizontal line, and both the first air inlet 101 and the second air inlet 102 are vertically arranged.

[0058] In this embodiment, since both the first air inlet 101 and the second air inlet 102 are vertically arranged, it is convenient to make the air duct shell 1 swing up and down while keeping the wet curtain assembly stationary.

[0059] In one embodiment, the air duct shell 1 includes a first inlet section 104, a second inlet section 105, and an outlet section 106 that are connected to each other. The first inlet section 104 is provided with a first air inlet 101, the second inlet section 105 is provided with a second air inlet 102, and the outlet section 106 is provided with an air outlet 103. The first inlet section 104 and the outlet section 106 are connected by a smooth curved surface, and the second inlet section 105 and the outlet section 106 are connected by a smooth curved surface.

[0060] In this embodiment, the first inlet section 104 and the outlet section 106 are connected by a smooth curved surface, and the second inlet section 105 and the outlet section 106 are connected by a smooth curved surface. This can reduce the resistance of air flowing from the first air inlet 101 and the second air inlet 102 to the air outlet 103, making the air intake smooth and continuous, and having little impact on the wind speed.

[0061] In one embodiment, along the airflow direction, the first inlet section 104 includes a first curved portion 1041 that bends toward the air outlet 103 on the side away from the outlet section 106, and / or the second inlet section 105 includes a second curved portion 1051 that bends toward the air outlet 103 on the side away from the outlet section 106.

[0062] In this embodiment, since the first curved portion 1041 bends toward the air outlet 103 on the side away from the outlet section 106, and the second curved portion 1051 bends toward the air outlet 103 on the side away from the outlet section 106, it can avoid the air intake of the first air inlet 101 and the air intake of the second air inlet 102 from directly clashing, thereby reducing the air volume and air speed of the air outlet 103. At the same time, it can reduce the resistance of air flowing from the first air inlet 101 and the second air inlet 102 to the air outlet 103, making the air intake continuous and smooth, and having a smaller impact on the air speed.

[0063] Specifically, such as Figure 2 As shown, the first inlet section 104 includes a first curved portion 1041 that bends toward the air outlet 103 on the side away from the outlet section 106, while the second inlet section 105 includes a second curved portion 1051 that bends toward the air outlet 103 on the side away from the outlet section 106.

[0064] In one embodiment not shown in the figure, the first inlet section 104 may include a first bend 1041, while the second inlet section 105 may be horizontally disposed on the side away from the outlet section 106.

[0065] In one embodiment not shown in the figure, the first inlet section 104 may be horizontally positioned on the side away from the outlet section 106, and the second inlet section 105 may include a second bend 1051.

[0066] In one embodiment, the first inlet section 104 and the second inlet section 105 are symmetrically arranged, and the connection between the first curved portion 1041 and the second curved portion 1051 is directly opposite to the center of the air outlet 103.

[0067] In this embodiment, since the connection between the first curved portion 1041 and the second curved portion 1051 is directly opposite to the center of the air outlet 103, the air intake volume of the first air inlet 101 and the second air inlet 102 can be equal.

[0068] Specifically in one embodiment, such as Figure 2 As shown, with the center of the connection between the first curved portion 1041 and the second curved portion 1051 as the vertex, tangents to the first curved portion and the second curved portion 1051 are drawn from this vertex. The included angle between the two tangents is B. The smaller B is, the closer the vertex is to the air outlet 103, the more complete the guidance of the air intake on both sides, and the smaller the air loss.

[0069] In one embodiment, the connection between the first curved portion 1041 and the second curved portion 1051 is not lower than the lowest position of the first air inlet 101 and the second air inlet 102.

[0070] In this embodiment, by ensuring that the connection between the first curved portion 1041 and the second curved portion 1051 is not lower than the lowest position of the first air inlet 101 and the second air inlet 102, the space occupied in the outlet section 106 can be avoided, and the loss of air can be reduced.

[0071] In one embodiment, a rotating mounting portion 107 is provided at the first air inlet 101 and the second air inlet 102.

[0072] In this embodiment, by providing a rotating mounting part 107 at the first air inlet 101 and the second air inlet 102, it is easy to realize the up and down swing of the air duct structure.

[0073] Specifically, such as Figure 3 As shown, multiple connecting strips are provided radially at the first air inlet 101 and the second air inlet 102. One end of the connecting strip is connected to the inner wall of the air duct shell 1, and the other end is connected to the rotating mounting part 107. The rotating mounting part 107 has a shaft hole, which can be fixedly connected to the output shaft of the oscillating motor or rotatably connected to the rotating shaft 7.

[0074] According to an embodiment of the present invention, in another aspect, a humidifying air outlet device is also provided, which may specifically be a cooling fan or a circulating fan.

[0075] In one embodiment, such as Figures 4 to 7 As shown, the humidifying air outlet device includes: the aforementioned air duct structure, support bracket 2, and evaporative cooling pad assembly. The air duct structure contains fan blades 6 and a main motor 5 that drives the fan blades 6 to rotate; two support brackets 2 are provided, and the air duct structure is rotatably positioned between the two support brackets 2; the evaporative cooling pad assembly is located on the side of the support bracket 2 facing away from the air duct structure.

[0076] In this embodiment, the duct shell 1 has two air inlets and one air outlet 103. Air enters through both air inlets simultaneously and is finally blown out through the air outlet 103. Compared with related technologies, the air intake area is doubled, which can increase the air intake volume. Support brackets 2 are provided outside the first air inlet 101 and the second air inlet 102. A wet curtain assembly is provided on the side of the support bracket 2 away from the duct structure. The wet curtain assembly is located outside the first air inlet 101 and the second air inlet 102. Therefore, the area covered by the wet curtain 4 at the air inlet of the duct can reach the maximum value of 1, which improves the cooling effect. In addition, the duct structure is rotatably arranged between the two support brackets 2, which can realize up and down swinging, and theoretically can realize 360° swinging in the vertical direction.

[0077] In one embodiment, at least one support bracket 2 is fixedly connected to a rotating shaft 7, and the air duct structure is able to rotate relative to the rotating shaft 7.

[0078] In this embodiment, the rotating shaft 7 allows the air duct structure to swing up and down stably.

[0079] Specifically in one embodiment, such as Figure 7 As shown, both left and right support brackets 2 are fixedly connected to a rotating shaft 7. A rotating mounting part 107 is provided at the first air inlet 101 and the second air inlet 102. The rotating shaft 7 passes through the rotating mounting part 107, and the rotating mounting part 107 is rotatably sleeved on the outside of the rotating shaft 7.

[0080] In one embodiment not shown in the figure, the rotating shaft 7 can be fixedly connected to only one side of the support bracket 2, and the oscillating motor can be fixedly installed on the other side of the support bracket 2. The output shaft of the oscillating motor is fixedly connected to the air duct shell 1.

[0081] In one embodiment, the evaporative cooling pad assembly includes an evaporative cooling pad support 3 and an evaporative cooling pad 4 disposed on the evaporative cooling pad support 3.

[0082] In this embodiment, the wet curtain bracket 3 is used to support the installation of the wet curtain 4. During assembly, the wet curtain 4 can be installed on the wet curtain bracket 3 first, and then the wet curtain bracket 3 can be fixedly installed on the support bracket 2.

[0083] In one specific embodiment, the support bracket 2 is provided with a mounting position for the wet curtain bracket 3, and the mounting position for the wet curtain bracket 3 is fixedly connected to the connecting part of the wet curtain bracket 3.

[0084] Specifically in one embodiment, such as Figure 8 , Figure 9 and Figure 11 As shown, the support bracket 2 is provided with a horizontal rib 201 extending in the horizontal direction. The installation position of the wet curtain bracket 3 is provided with two screw holes 202 on the horizontal rib 201. Two screw holes 301 are provided on both sides of the wet curtain bracket 3. When installing the wet curtain bracket 3, align the screw holes 301 on the wet curtain bracket 3 with the two screw holes 202 on the horizontal rib 201, and tighten the screws to achieve a fixed connection between the wet curtain bracket 3 and the support bracket 2.

[0085] The wet curtain bracket 3 is provided with a water baffle 302, and the support bracket 2 is provided with a clearance groove for avoiding the water baffle 302 of the wet curtain bracket 3.

[0086] In this embodiment, by providing an avoidance groove in the support bracket 2, which is used to avoid the water baffle 302 of the wet curtain bracket 3, the gap between the wet curtain bracket 3 and the support bracket 2 can be made smaller, thereby reducing the overall volume of the humidification air outlet equipment.

[0087] Specifically in one embodiment, such as Figure 11 As shown, the wet curtain bracket 3 is provided with two water baffles 302, and correspondingly, the support bracket 2 is provided with two clearance grooves.

[0088] Specifically, such as Figure 11 As shown, the water baffle 302 is tilted to prevent water from falling into areas outside the wet curtain support 3.

[0089] In one embodiment, the humidifying air outlet device further includes an air inlet screen 8, which is connected to the support bracket 2 and covers the wet curtain assembly inside it.

[0090] In this embodiment, the air inlet mesh cover 8 is used to protect the wet curtain 4 and prevent people from directly touching the wet curtain 4. The air inlet mesh cover 8 is connected to the support bracket 2 and surrounds both the wet curtain 4 and the wet curtain bracket 3, making the appearance more beautiful.

[0091] In one embodiment, the air inlet mesh cover 8 and the support bracket 2 are connected by a snap fastener.

[0092] In this embodiment, the connection between the air inlet mesh cover 8 and the support bracket 2 is simple and convenient.

[0093] Specifically, such as Figure 8 and Figure 12 As shown, the support bracket 2 is provided with a first engaging part, and the air inlet mesh cover 8 is provided with a second engaging part 801. The first engaging part and the second engaging part 801 are engaged in a corresponding manner.

[0094] Specifically, the humidification air outlet equipment also includes components such as a water tank, an inlet water pipe, and a outlet water pipe. The inlet water pipe is used to supply water to the wet curtain 4, and the outlet water pipe is used to guide the water falling from the wet curtain 4 into the water tank for reuse.

[0095] Specifically, the support bracket 2 is also provided with holes for water supply pipes and drainage pipes to pass through.

[0096] Specifically, the humidifying air outlet device also includes a support base, and the support bracket 2 is fixedly installed on the support base.
