Description

Technical Field

[0001] This utility model relates to the field of fresh air technology, and more specifically, to an air handling device and a rain cover. Background Technology

[0002] Existing fresh air systems and air conditioners have ductwork that connects to the outside. When the fresh air mode is activated, this duct draws outdoor air into the room. Because the air inlet extending outdoors is under negative pressure, rainwater can easily be drawn into the duct during rainy days. To overcome this problem, a raised rain cover is typically installed at the front end of the air inlet to prevent rainwater from entering.

[0003] However, during actual installation, the rain cover may be installed backwards. When installed backwards, the rain cover will act as a bowl to catch rainwater, and all the rainwater collected by the rain cover will flow back into the fresh air duct, which will aggravate the water absorption of the fresh air duct and reduce the fresh air volume. Utility Model Content

[0004] This utility model embodiment provides a rain cover, which includes:

[0005] The cylindrical body includes an air inlet and an air outlet opposite to the air inlet; and

[0006] The cover extends from the air inlet end toward the direction away from the air outlet end;

[0007] The cover is provided with a water leakage hole.

[0008] In one illustrative embodiment, the drainage hole is located in the middle of the cover, on the side of the cover closer to the cylinder, or on the side of the cover away from the cylinder.

[0009] In one illustrative embodiment, the cover includes:

[0010] The first rain shield is constructed as a groove with an arched cross-section, one end of which is connected to the air inlet; and,

[0011] The second rain shield covers the end of the first rain shield that is away from the cylinder.

[0012] In one illustrative embodiment, the drainage hole is disposed on the first rain shield and located at one end of the first rain shield near the boundary line of the second rain shield; or,

[0013] The drainage hole is located at the junction of the first rain shield and the second rain shield; or,

[0014] The water leakage hole is provided on the second rain shield and is located at the end of the second rain shield that is closer to the first rain shield.

[0015] In one illustrative embodiment, multiple drainage holes are provided, and the multiple drainage holes are arranged sequentially along the extension direction of the boundary line.

[0016] In one illustrative embodiment, the cylinder is cylindrical.

[0017] The inner wall of the first rain shield is a semi-cylindrical surface that is coaxial with the inner wall of the cylinder and has the same diameter;

[0018] The outer wall of the first rain shield is a semi-cylindrical surface that is coaxial with the outer wall of the cylinder and has the same diameter.

[0019] In one illustrative embodiment, a grille is also provided inside the air inlet.

[0020] In one illustrative embodiment, the top surface of the cover is provided with a directional marker, which is used to indicate that the top surface of the cover is facing upwards.

[0021] In one illustrative embodiment, the diameter of the drainage hole is 5–15 mm.

[0022] In one illustrative embodiment, a one-way valve is provided in the leakage through-hole, which can only allow fluid flowing from inside the cover to outside the cover.

[0023] This application discloses an air handling device, which includes a rain cover as described above and a fresh air duct, with the cylindrical body fitted over one end of the fresh air duct.

[0024] When the rain cover is installed on the fresh air duct in the wrong way, the drainage hole is at the lowest position of the rain cover. The rainwater received inside the rain cover can flow out through the drainage hole, thereby preventing rainwater from accumulating inside the rain cover and entering the fresh air duct. This will prevent the water from entering the fresh air duct from getting worse and increase the air intake of the fresh air duct.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0039] like Figures 1-3 As shown, Figures 1-3 The structure of a rain cover 100 according to an embodiment of this application is shown. The rain cover 100 includes a cylindrical body 1 and a cover body 2. The cover body 2 is connected to the cylindrical body 1.

[0040] The cylinder 1 has a cylindrical structure. The shape of the cylinder 1 is not limited; it can be a straight cylinder or a curved cylinder, and its cross-section can be circular, rectangular, or elliptical. The cylinder 1 includes an air inlet end 11 and an air outlet end 12. The air inlet end 11 and the air outlet end 12 are arranged opposite each other. The cylinder 1 is arranged horizontally.

[0041] The cover 2 can be constructed as an upwardly arched shell. The cover 2 is connected to the air inlet end 11 of the cylinder 1, and extends from the air inlet end 11 away from the air outlet end 12. The cover 2 is connected to the upper part of the air inlet end 11. The cover 2 and the cylinder 1 can be an integrally formed structure. An inner cavity 25 is provided inside the cover 2, with an air inlet 26 at the bottom of the inner cavity 25 and an air outlet 27 on the side of the inner cavity 25 near the cylinder 1, which communicates with the air inlet end 11 of the cylinder 1. A water leakage hole 20 is provided at the top of the cover 2. That is, the water leakage hole 20 is located on the side of the cover 2 away from the air inlet 26. The water leakage hole 20 penetrates the cover 2. The shape of the water leakage hole 20 is not limited; it can be a circular hole, an elliptical hole, a square hole, or a triangular hole.

[0042] When using the rain cover 100, simply install the outlet end 12 of the sleeve onto the end of the fresh air duct 200 that extends outdoors. For example, the outlet end 12 of the sleeve can be fitted onto the end of the fresh air duct 200. The correct installation method for the rain cover 100 is with the top of the cover 2 facing upwards; the incorrect installation method is with the top of the cover 2 facing downwards. After the rain cover 100 is installed on the fresh air duct 200 in the correct manner, it can block the inlet of the fresh air duct 200 during rain, preventing rainwater from entering the fresh air duct 200 due to its suction. When the rain cover 100 is installed on the fresh air duct 200 in the wrong way, the water leakage hole 20 is at the lowest position of the rain cover 100. The rainwater received inside the rain cover 100 can flow out of the rain cover 100 through the water leakage hole 20, thereby preventing rainwater from accumulating inside the rain cover 100 and entering the fresh air duct 200, thus preventing the water ingress into the fresh air duct 200 from worsening and increasing the air intake of the fresh air duct 200.

[0043] In one illustrative embodiment, the water leakage hole 20 is located at the top of the cover 2 on the side away from the cylinder 1.

[0044] In this way, the drainage hole 20 is located as far away from the cylinder 1 as possible, preventing rainwater from entering the air inlet 11 of the cylinder 1 and then the fresh air duct 200 when the rain cover 100 is installed on the fresh air duct 200 according to the correct installation method. When the rain cover 100 is installed on the fresh air duct 200 according to the correct installation method, the fresh air duct 200 will not draw in rainwater. If the rain cover 100 is installed on the fresh air duct 200 according to the incorrect installation method, the rainwater received inside the rain cover 100 can still flow out of the rain cover 100 through the drainage hole 20.

[0045] In one illustrative embodiment, the water leakage hole 20 may also be provided on the side of the cover 2 near the cylinder 1 or in the middle of the cover 2.

[0046] The water leakage hole 20 is located on the side of the cover 2 near the cylinder 1 or in the middle of the cover 2. After the rain cover 100 is installed on the fresh air duct 200 in an incorrect way, the rainwater received inside the rain cover 100 can flow out of the rain cover 100 through the water leakage hole 20.

[0047] In one illustrative embodiment, the cover 2 includes a first rain shield 21 and a second rain shield 22. The first rain shield 21 is constructed as a groove with an upwardly arched cross-section. The groove can be a straight strip, and its extension direction is the same as the axial direction of the cylinder 1. One end of the first rain shield 21 is connected to the upper half of the air inlet 11 of the cylinder 1. The second rain shield 22 covers the end of the first rain shield 21 away from the cylinder 1. The second rain shield 22 is constructed as a plate, and can be spherical. The second rain shield 22 arches towards the side opposite to the first rain shield 21.

[0048] The first rain shield 21 has an upwardly arched groove structure, allowing rainwater to slide down its outer wall and prevent water accumulation. Simultaneously, the second rain shield 22 covers the end of the first rain shield 21 facing away from the cylinder 1, also serving to block rain and prevent rainwater from entering below it. This structure of the cover 2 effectively protects against rain, preventing rainwater from entering the cylinder 1, while simultaneously allowing air intake at the cylinder 1's air inlet 11 to remain sufficiently large.

[0049] In one illustrative embodiment, a boundary line exists between the first rain shield 21 and the second rain shield 22, and a drainage hole 20 is disposed on the boundary line between the first rain shield 21 and the second rain shield 22. The drainage hole 20 may be disposed in the middle section of the boundary line. A portion of a single drainage hole 20 is located on the first rain shield 21, and another portion is located on the second rain shield 22.

[0050] In this way, the drainage hole 20 is located on the boundary line between the first rain shield 21 and the second rain shield 22, so that the drainage hole 20 is as far away from the cylinder 1 as possible. This can prevent rainwater from entering the air inlet end 11 of the cylinder 1 through the drainage hole 20 when the rain cover 100 is installed on the fresh air duct 200 in the correct installation manner. At the same time, if the rain cover 100 is installed on the fresh air duct 200 in the wrong installation manner, the rainwater received inside the rain cover 100 can still flow out of the rain cover 100 through the drainage hole 20.

[0051] In one illustrative embodiment, all the water leakage holes 20 are provided on the first rain shield 21, and the water leakage holes 20 are located on the top of the first rain shield 21 near the end of the second rain shield 22.

[0052] In this way, the water leakage hole 20 is located at the end of the first rain shield 21 near the second rain shield 22, so that the water leakage hole 20 is as far away from the cylinder 1 as possible. This can prevent rainwater from entering the air inlet end 11 of the cylinder 1 through the water leakage hole 20 when the rain cover 100 is installed on the fresh air duct 200 in the correct installation manner. At the same time, if the rain cover 100 is installed on the fresh air duct 200 in the wrong installation manner, the rainwater received inside the rain cover 100 can still flow out of the rain cover 100 through the water leakage hole 20.

[0053] In one illustrative embodiment, all the drainage holes 20 are provided on the second rain shield 22, and the drainage holes 20 are located at the top of the end of the second rain shield 22 near the first rain shield 21. The drainage holes 20 may be located in the middle section near the boundary line 24.

[0054] In this way, the water leakage hole 20 is located at the end of the second rain shield 22 near the first rain shield 21, so that the water leakage hole 20 is as far away from the cylinder 1 as possible. This can prevent rainwater from entering the air inlet end 11 of the cylinder 1 through the water leakage hole 20 when the rain cover 100 is installed on the fresh air duct 200 in the correct installation manner. At the same time, if the rain cover 100 is installed on the fresh air duct 200 in the wrong installation manner, the rainwater received inside the rain cover 100 can still flow out of the rain cover 100 through the water leakage hole 20.

[0055] In one illustrative embodiment, multiple drainage holes 20 are provided. For example, three drainage holes 20 may be provided. The multiple drainage holes 20 are arranged sequentially along the extension direction of the boundary line 24 between the first rain shield 21 and the second rain shield 22. There is a gap between two adjacent drainage holes 20.

[0056] Multiple drainage holes 20 are provided to increase drainage volume and accelerate the discharge of water from the rain cover 100, preventing water accumulation inside the rain cover 100. Furthermore, even if the rain cover 100 is installed incorrectly on the fresh air duct 200, regardless of the installation angle, at least one drainage hole 20 will be located at the lowest point of the rain cover 100, effectively draining rainwater from inside the rain cover 100 and preventing rainwater from entering the fresh air duct 200.

[0057] In one illustrative embodiment, the cylinder 1 is cylindrical. The inner diameter of the cylinder 1 is the same as the outer diameter of the fresh air duct 200. The inner wall of the first rain shield 21 is a semi-cylindrical surface, which is coaxial with the inner wall of the cylinder 1, and the diameter of the semi-cylindrical surface is the same as that of the inner wall of the cylinder 1. The inner wall of the first rain shield 21 smoothly transitions with the inner wall of the cylinder 1.

[0058] The outer wall of the first rain shield 21 is a semi-cylindrical surface, which is coaxial with the outer wall of the cylinder 1, and the diameter of the semi-cylindrical surface is the same as that of the outer wall of the cylinder 1. The outer wall of the first rain shield 21 transitions smoothly with the outer wall of the cylinder 1.

[0059] The second rain shield 22 is constructed as a spherical panel. The diameter of the inner wall of the second rain shield 22 is equal to the diameter of the inner wall of the cylinder 1, and the diameter of the outer wall of the second rain shield 22 is equal to the diameter of the outer wall of the cylinder 1. The inner wall of the second rain shield 22 and the inner wall of the first rain shield 21 have a smooth transition. The outer wall of the second rain shield 22 and the outer wall of the first rain shield 21 also have a smooth transition.

[0060] Thus, the first rain shield 21 has a semi-cylindrical structure with the same diameter as the cylinder 1, which facilitates the passage of the rain cover 100 through the through-hole in the wall to the outside after it is installed on the fresh air duct 200, making the installation of the fresh air duct 200 easier. At the same time, the outer wall of the second rain shield 22 is spherical, which can guide the rain cover 100 through the through-hole in the wall and reduce the impact when the rain cover 100 passes through the through-hole.

[0061] In one illustrative embodiment, a grille 3 is provided inside the air inlet end 11 of the cylinder 1. The grille 3 covers the air inlet end 11 of the cylinder 1. A plurality of ventilation holes 31 are provided on the grille 3.

[0062] The air inlet 11 of the cylinder 1 is provided with a grille 3 to block foreign objects larger than the air vent 31 of the grille 3, so as to prevent foreign objects from entering the fresh air duct. Such foreign objects are, for example, insects, birds, mice, etc.

[0063] In one illustrative embodiment, a directional marker 23 is provided on the top surface of the cover 2. The directional marker 23 is used to indicate that the top surface of the cover 2 is facing upwards. The directional marker 23 can be text and / or a pattern. In this embodiment, the directional marker 23 is the text "This side is up".

[0064] When installing the rain cover 100, the indicator markings can indicate the correct installation position of the rain cover 100, reducing the possibility of operator error and the probability of incorrect installation of the rain cover 100.

[0065] In one illustrative embodiment, the diameter of the water leakage hole 20 is 5mm to 15mm.

[0066] The diameter of the drainage hole 20 is 5mm to 15mm. This can meet the drainage needs of the rain cover 100 when it is installed incorrectly, preventing rainwater from accumulating inside the rain cover 100. It can also ensure that very little water enters the drainage hole 20 when the rain cover 100 is installed correctly, preventing the fresh air duct 200 from sucking in rainwater.

[0067] In one illustrative embodiment, a one-way valve is provided within the drainage hole 20. The number of one-way valves is the same as the number of drainage holes 20, with one one-way valve provided in each drainage hole 20. This one-way valve can be a diaphragm-type one-way valve. The one-way valve is configured to allow only fluid flowing from inside the housing 2 to the outside of the housing 2 to pass through.

[0068] In this way, when the rain cover 100 is installed correctly, the one-way valve can block rainwater from entering the rain cover 100 through the drain hole 20. When the rain cover 100 is installed incorrectly, the one-way valve can be opened, allowing rainwater to flow out of the rain cover 100 smoothly through the drain hole 20.

[0069] This embodiment also proposes an air handling device capable of both air intake and exhaust. Its air handling function is not limited, for example, it can perform at least one of the following: temperature control, humidification, purification, and circulation. This air handling device includes, but is not limited to, an air conditioner. It can also be a purifier, humidifier, fan, etc. Once the specific type of air handling device is determined, those skilled in the art will understand its other components, which will not be elaborated upon here.

[0070] This air handling unit has a fresh air function. The air handling unit includes a rain cover 100 and a fresh air duct 200 as described above. The air outlet 12 of the rain cover 100 is fitted onto one end of the fresh air duct 200.
