Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to a hidden window drainage structure. Background Art

[0002] On rainy days, rainwater will fall on the window glass and flow into the glass frame along the glass. When the water inside the glass frame cannot be drained away, it will cause indoor humidity and breed bacteria. Therefore, existing windows are equipped with drain holes to drain the water inside the glass frame.

[0003] However, the height difference between the drain outlet and the first water inlet in the existing window is small, and the drainage capacity is poor. When encountering strong winds and rains, the drainage volume is often less than the water intake volume, resulting in water overflow. In the south, there are often rainy days that last for many days. Due to the weak drainage capacity, water will always remain in the glass frame, causing indoor humidity and making people uncomfortable to live in.

[0004] Therefore, a structure for quickly solving water accumulation in the glass frame is now needed. Utility Model Content

[0005] Based on this, in order to solve the problem of water accumulation inside the glass frame, the utility model provides a hidden window drainage structure, and its specific technical solution is as follows:

[0006] A hidden window drainage structure, comprising an aluminum alloy bottom frame, window glass, a window frame, and a mounting profile, wherein the upper portion of the aluminum alloy bottom frame is connected to the window frame, and one side is connected to the mounting profile, and the window glass is fixed to the window frame. The structure is characterized in that it also includes a siphon;

[0007] The window frame is provided with a water inlet channel for guiding the flow of liquid;

[0008] The aluminum alloy bottom frame, the window frame and the mounting profile are surrounded to form a cavity, and the cavity is communicated with the water inlet channel;

[0009] A first water inlet is provided on one side of the mounting profile, a first water outlet is provided at the bottom, and a water outlet channel is provided inside. The first water inlet and the first water outlet are provided at both ends of the water outlet channel. The water outlet channel is connected to the cavity through the first water inlet. The bottom of the mounting profile is at the same level as the bottom of the aluminum alloy bottom frame.

[0010] The siphon is fixedly mounted on the mounting profile. The siphon is divided into a first suction pipe and a second suction pipe that are connected. The first suction pipe is located inside the cavity, and the second suction pipe is located in the water outlet channel.

[0011] Furthermore, the first water inlet of the installation profile is opened at the bottom where the installation profile contacts the cavity.

[0012] Furthermore, the mounting profile is provided with a receiving groove protruding toward the aluminum alloy bottom frame, and the receiving groove is communicated with the water outlet channel.

[0013] Furthermore, a second water outlet is provided at the bottom of the mounting profile, and the second water outlet is communicated with a port of the second suction pipe of the siphon pipe.

[0014] Furthermore, the connection point between the first suction pipe and the second suction pipe of the siphon is a first high point, and the first high point is higher than the top of the cavity in the vertical direction.

[0015] Furthermore, the first suction pipe of the siphon is arranged in a curved shape.

[0016] Furthermore, the first straw is bent into at least three sections.

[0017] Furthermore, the first straw is divided into a first curved section, a second curved section and a third curved section which are connected in sequence;

[0018] One end of the first curved section is communicated with the second straw, and the connections between the first curved section, the second curved section and the third curved section are all bent.

[0019] Furthermore, the connection point between the first curved segment and the second straw is higher than the connection point between the second curved segment and the third curved segment, and the connection point between the first curved segment and the second curved segment is higher than the end of the first straw.

[0020] Furthermore, the port of the first suction pipe of the siphon pipe is located at one quarter of the cavity close to the aluminum alloy bottom frame.

[0021] This solution has the beneficial effect of forming a cavity surrounded by the aluminum alloy bottom frame, window frame, and mounting profile. This cavity is connected to the water inlet channel. A first water inlet is provided on one side of the mounting profile, and a first water outlet is provided at the bottom. When rainfall is light, rainwater flows into the cavity through the water inlet channel, then flows out through the first water inlet and out through the first water outlet. When rainfall is heavy, water accumulates in the cavity because the discharge volume of the first water outlet is lower than the intake volume. At this time, the siphon tube starts to absorb water, and the rainwater in the cavity is quickly drained by the siphon tube, thus forming a circulation system to ensure that water does not accumulate in the cavity.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0030] like Figures 1 and 2As shown, a hidden window drainage structure in one embodiment of the present invention includes an aluminum alloy bottom frame 1, window glass 2, window frame 3 and mounting profile 4. The upper portion of the aluminum alloy bottom frame 1 is connected to the window frame 3, and one side is connected to the mounting profile 4. The window glass 2 is fixed to the window frame 3 and further includes a siphon 5. The window frame 3 is provided with a water inlet channel 31 for guiding the flow of liquid. The aluminum alloy bottom frame 1, the window frame 3 and the mounting profile 4 surround a cavity 100, which is communicated with the water inlet channel 31. One side of the mounting profile 4 A first water inlet 41 is provided on the side, a first water outlet 42 is provided at the bottom, and a water outlet channel 43 is provided inside. The two ends of the water outlet channel 43 are the first water inlet 41 and the first water outlet 42. The water outlet channel 43 is connected with the cavity 100 through the first water inlet 41. The bottom of the mounting profile 4 and the bottom of the aluminum alloy bottom frame 1 are at the same level; the siphon tube 5 is fixedly installed on the mounting profile 4, and the siphon tube 5 is divided into a first suction tube 51 and a second suction tube 52 connected to each other. The first suction tube 51 is located inside the cavity 100, and the second suction tube 52 is located in the water outlet channel 43.

[0031] In one embodiment, the aluminum alloy bottom frame 1, window glass 2, window frame 3, and mounting profile 4 are all based on existing technologies. The window glass 2 is fixedly mounted on the window frame 3, and the aluminum alloy bottom frame 1 and mounting profile 4 jointly support the window frame 3. However, this existing structure easily causes rainwater to seep between the aluminum alloy bottom frame 1, window frame 3, and mounting profile 4 during rainy days. The existing drain outlet cannot meet the drainage requirements, resulting in persistent water accumulation between the aluminum alloy bottom frame 1, window frame 3, and mounting profile 4.

[0032] Therefore, in this embodiment, a first water outlet 42 is opened at the bottom of the mounting profile 4, and rainwater first enters the cavity 100 through the water inlet channel 31 opened on the window frame 3, and the rainwater inlet channel 31 flows into the cavity 100, and then flows out from the first water outlet 42 through the first water inlet 41.

[0033] During heavy rainstorms, when the rainfall is high, rainwater flows into cavity 100 through water inlet channel 31. The drainage capacity of first water outlet 42 is insufficient to drain all the rainwater, causing it to gradually accumulate in cavity 100. When the rainwater in cavity 100 reaches a certain level, siphon tube 5 mounted on mounting profile 4 draws water from cavity 100, thereby directly clearing the water. The water level here refers to the lowest bend point of siphon tube 5.

[0034] The height difference between the water inlet channel 31 and the first water outlet 42 is 80mm to 110mm. According to Bernoulli's principle, water flows faster when the height difference is greater. However, the height difference of the existing water inlet channel 31 is 20mm to 35mm. Therefore, rainwater in the mounting profile 4 will be discharged from the first drain outlet at a faster rate. The first drain outlet is located at the bottom of the mounting profile 4, making its installation more discreet and more aesthetically pleasing to the window.

[0035] Since the ordinary siphon tube 5 cannot directly produce the siphon effect, the siphon tube 5 in this embodiment adopts a self-starting siphon tube 5.

[0036] The cavity 100 also has a sealing function. When it rains heavily, due to the large impact force of rainwater, as the rainwater continuously washes the window frame 3, some rainwater can easily penetrate into the window frame 3 on the indoor side. When the cavity 100 is filled with rainwater, the rainwater inside it will act as a buffer zone to offset the impact force of rainwater in heavy rain.

[0037] like Figures 1 and 2 As shown, in other embodiments, the first water inlet 41 of the installation profile 4 is opened at the bottom where the installation profile 4 contacts the cavity 100 .

[0038] In one embodiment, the height of the first water inlet 41 opened on the mounting profile 4 determines the height of the water storage inside the cavity 100. Therefore, in order to ensure that no water accumulates inside the cavity 100, the first water inlet 41 is set at the lowest point where the mounting profile 4 contacts the cavity 100, ensuring that rainwater flows into the cavity 100 from the water inlet channel 31 and flows into the first water inlet 41 as soon as possible.

[0039] like Figures 1 and 2 As shown, in other embodiments, the mounting profile 4 is provided with a receiving groove 44 protruding toward the aluminum alloy bottom frame 1 , and the receiving groove 44 is communicated with the water outlet channel 43 .

[0040] In one embodiment, the outer wall of the mounting profile 4 is provided with a receiving groove 44, which is fixedly connected to the bottom frame of the aluminum box, thereby forming a surface surrounding the outlet cavity 100. The receiving groove 44 can further store rainwater when the water outlet channel 43 overflows. Since the receiving groove 44 is a portion of the mounting profile 4 that is provided, the width of the receiving groove 44 is wider than the width of the first water outlet 42. Therefore, the flow rate is further accelerated when the upper and lower widths are different.

[0041] like Figures 1 and 2As shown, in another embodiment, the mounting profile 4 has a receiving groove 44 projecting toward the aluminum alloy base frame 1. The outer wall of the receiving groove 44 contacts the cavity 100, and a second water inlet may be provided on the contact surface. Rainwater enters the receiving groove 44 through the second water inlet, flows along the inner wall of the receiving groove 44 into the water outlet channel 43, and then flows out through the water outlet. The cooperation between the first water inlet 41 and the second water inlet further accelerates the outflow of rainwater from the cavity 100.

[0042] like Figures 1 and 2 As shown, in other embodiments, a second water outlet 45 is further provided at the bottom of the mounting profile 4 , and the second water outlet 45 is communicated with a port of the second suction pipe 52 of the siphon pipe 5 .

[0043] In one embodiment, during heavy rain, the cavity 100 and the water outlet channel 43 may be filled with rainwater. If the siphon tube 5 draws rainwater from the cavity 100 and then discharges it through the water outlet channel 43, the drainage volume in the water outlet channel 43 will increase, causing negative pressure on drainage.

[0044] In order to ensure that the siphon tube 5 can quickly drain the rainwater in the cavity 100 and discharge it out of the mounting profile 4, the second water outlet 45 at the bottom of the mounting profile 4 is connected to the port of the second suction pipe 52 of the siphon tube 5, so that the rainwater absorbed by the siphon tube 5 will be discharged directly from the second water outlet 45, thereby increasing the drainage capacity of the mounting profile 4.

[0045] like Figures 1 and 2 As shown, in other embodiments, the connection point between the first suction pipe 51 and the second suction pipe 52 of the siphon pipe 5 is a first high point 53 , and the first high point 53 is higher than the top of the cavity 100 in the vertical direction.

[0046] In one embodiment, the first high point 53 of the siphon tube 5 is the highest point. For siphoning to occur, the highest point of the siphon tube 5 must be above the water surface. During heavy rain, the cavity 100 can easily fill with rainwater. Therefore, the highest point of the siphon tube 5 must be above the highest point of the cavity 100 to ensure a more effective siphoning effect. If the amount of rainwater is insufficient to fill the cavity 100, drainage can be achieved through the first water outlet 42.

[0047] like Figures 1 and 2 As shown, in other embodiments, the siphon tube 5 is arranged in a curved shape.

[0048] In one embodiment, to ensure self-priming, the portion of the siphon 5 within cavity 100 is curved. When rainwater fills cavity 100, the water surface completely covers the curved portion of the siphon 5. Due to pressure, the rainwater flows into the portion of the siphon 5 within cavity 100. The difference in pressure between the inside and outside of the pipe causes the rainwater to flow further into the siphon 5 until it passes the bend in the siphon 5. Under the influence of gravity, the rainwater flows past the upper bend and toward the lower bend in the siphon 5. Then, under the influence of inertia and pressure, the rainwater flows through the first high point 53 of the siphon 5, completing the automatic priming process of the siphon 5.

[0049] like Figures 1 and 2 As shown, in other embodiments, the first suction pipe 51 is bent into at least three sections.

[0050] In one embodiment, due to the two-section curved tube, its outlet port needs to be blocked, the inlet port placed in water, and then the outlet port opened. This allows the water to siphon within the tube under the effects of pressure and inertia. However, the siphon tube 5 in this embodiment is placed within the mounting profile 4, making it difficult to achieve self-activation of the two-section curved tube. Therefore, to ensure the smooth operation of the automatic activation of the siphon tube 5, the first suction pipe 51 has a three-section curved shape. The pressure and inertia of rainwater cause the siphon tube 5 to automatically activate the siphon.

[0051] like Figures 1 and 2 As shown, in other embodiments, the first straw 51 is divided into a first curved section 54, a second curved section 55 and a third curved section 56 which are connected in sequence;

[0052] One end of the first curved section 54 is connected to the second straw 52 , and the connections between the first curved section 54 , the second curved section 55 and the third curved section 56 are all bent.

[0053] In one embodiment, the connection point among the second suction pipe 52, the first curved section 54, the second curved section 55 and the third curved section 56 is curved. The curved setting can reduce the resistance of rainwater flowing through the connection point among the second suction pipe 52, the first curved section 54, the second curved section 55 and the third curved section 56, thereby increasing the flow rate of rainwater in the siphon 5.

[0054] like Figures 1 and 2 As shown, in other embodiments, the connection point of the first curved segment 54 and the second straw 52 is higher than the connection point of the second curved segment 55 and the third curved segment 56 , and the connection point of the first curved segment 54 and the second curved segment 55 is higher than the end of the first straw 51 .

[0055] In one embodiment, in the height direction, the height of the connection point of the second suction pipe 52, the first curved section 54, the second curved section 55 and the third curved section 56 is:

[0056] The connection point between the first curved section 54 and the second straw 52 is higher than the connection point between the second curved section 55 and the third curved section 56. The connection point between the second curved section 55 and the third curved section 56 is higher than the connection point between the first curved section 54 and the second curved section 55. The connection point between the first curved section 54 and the second curved section 55 is higher than the opening of the third curved section 56.

[0057] When the water level in cavity 100 is higher than the connection point between the second curved section 55 and the third curved section 56, due to the principle of communicating vessels, rainwater will fill the third curved section 56 and flow past the connection point between the second curved section 55 and the third curved section 56. Under the action of gravity, the rainwater will reach the connection point between the first curved section 54 and the second curved section 55. Furthermore, under the action of inertia and pressure, the rainwater will fill the first curved section 54 and flow past the connection point between the second suction pipe 52 and the first curved section 54, achieving siphoning. This further accelerates the drainage of rainwater from cavity 100.

[0058] like Figures 1 and 2 As shown, in other embodiments, the end of the first suction pipe 51 of the siphon pipe 5 is located at one quarter of the cavity 100 close to the aluminum alloy bottom frame 1 .

[0059] In one embodiment, the siphon tube 5 has certain requirements for the water level, that is, the water level must not be higher than the highest point of the siphon tube 5, and must also be higher than the bending point of the second height of the siphon tube 5. Therefore, for convenience, when the rainfall is not large, drainage can be completed by relying solely on the first water inlet 41.

[0060] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
