Description

Technical Field

[0001] The utility model belongs to the technical field of casement windows, and particularly relates to a casement window with a hidden hydrophobic structure. Background Technique

[0002] In modern architectural design, windows, as key components connecting the interior and exterior, directly affect the ventilation, lighting, heat insulation, sound insulation, and waterproofing effects of buildings. Although traditional casement windows have advantages such as a large opening area, good ventilation effect, and strong sealing performance, they often have deficiencies in drainage design. Conventional casement windows achieve drainage by setting drainage holes at the bottom of the window frame. When dealing with harsh weather, they often face problems such as rainwater penetration and poor drainage. Although the traditional drainage hole design can drain some accumulated water, it is easily interfered by external factors. For example, when there is strong wind pressure and a large amount of rain, rainwater is likely to penetrate into the room. In addition, traditional drainage holes are also prone to becoming channels for dust to enter, affecting the indoor environment.

[0003] To solve the above problems, some improved drainage window frame designs have emerged on the market, such as hidden drainage window frames. These designs have improved the drainage effect to a certain extent, but there are still problems such as insufficient drainage speed and unsatisfactory dust and rain prevention effects. Therefore, a more efficient and reliable drainage solution is needed to meet the high requirements of modern buildings for window performance. Summary of the Utility Model

[0004] Aiming at the above problems, the purpose of the utility model is to provide a casement window with a hidden hydrophobic structure to solve the problems that the existing hidden drainage window frames still have insufficient drainage speed and unsatisfactory dust and rain prevention effects.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a casement window with a hidden hydrophobic structure, including a hydrophobic component. The hydrophobic component includes a cover plate. A one-way channel composed of multiple Tesla valves is formed on the bottom surface of the cover plate. The two ends of the one-way channel respectively penetrate through the two end faces of the cover plate and form a water inlet and a water outlet. The cover plate is fixedly pressed on the window frame by screws. The drainage hole opened on the window frame is opposite to and communicated with the port of the water outlet.

[0006] The beneficial effect of the utility model is that the special structure of the one-way channel enables the water body in the window frame to quickly drain through the drainage hole under the action of gravity, improving the drainage efficiency and avoiding the problem of water accumulation caused by poor drainage. When external dust, rainwater, etc. try to enter the room through the drainage hole, due to the reverse resistance of the one-way channel, these impurities are effectively blocked outside the room, keeping the room clean and dry.

[0007] To ensure the one-way diversion effect of the one-way channel;

[0008] As a further improvement of the above technical solution: The direction from the water inlet to the water outlet is the forward direction of the Tesla valve forming a one-way channel.

[0009] The beneficial effect of this improvement is that when rainwater enters the one-way channel through the water inlet and flows inside, the fluid is split into two streams at each turning point, and then these two streams of fluid will converge again at the next intersection point, thus achieving an acceleration effect; when the three-dimensional flows reversely in the one-way channel, the backflow resistance gradually increases, thus achieving one-way diversion.

[0010] To ensure the sealing performance at the connection between the one-way channel and the window frame;

[0011] As a further improvement of the above technical solution: The bottom surface of the cover plate is in smooth contact with the window frame, and the number of the screws is multiple.

[0012] The beneficial effect of this improvement is that the cover plate can be firmly attached to the window frame under the fastening of multiple screws, and the sealing performance at the connection between the one-way channel and the window frame is ensured as much as possible.

[0013] To effectively collect the water flow in the window frame;

[0014] As a further improvement of the above technical solution: The number of the drain holes is two and they are respectively opened at both ends of the side surface of the window frame.

[0015] The beneficial effect of this improvement is that the two groups of drain holes and their cooperating hydrophobic components can effectively collect and discharge the accumulated water flow in the window frame.

[0016] To effectively discharge the water body;

[0017] As a further improvement of the above technical solution: The water outlet is of an L-shaped structure, and the port of the water outlet is in smooth contact with the drain hole.

[0018] The beneficial effect of this improvement is that the water body in the one-way channel can be smoothly discharged through the water outlet and the drain hole.

[0019] To prevent the water body from entering the interior of the window frame through the screw holes opened on the window frame for connecting the screws;

[0020] As a further improvement of the above technical solution: The cover plate is provided with counterbores for inserting the screws, and sealing rings are installed inside the counterbores.

[0021] The beneficial effect of this improvement is that the sealing rings are elastically deformed after being squeezed by the cover plate and the window frame, thus effectively preventing the screw holes opened on the window frame.

[0022] The parts not involved in this device are the same as the prior art or can be implemented by using the prior art. Description of the Drawings

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0029] Example 1:

[0030] Such as Figure 1As shown in Fig. 4, a casement window with a hidden hydrophobic structure includes a hydrophobic component 3. The hydrophobic component 3 includes a cover plate 31. A one-way channel 33 composed of multiple Tesla valves is formed on the bottom surface of the cover plate 31. Both ends of the one-way channel 33 penetrate through the two end faces of the cover plate 31 and form a water inlet 34 and a water outlet 35. The cover plate 31 is fixed on the window frame 1 by screws 32. The drain hole 2 opened on the window frame 1 is opposite to and communicated with the port of the water outlet 35. The special structure of the one-way channel 33 enables the water body in the window frame 1 to quickly drain through the drain hole 2 under the action of gravity, improving the drainage efficiency and avoiding the water accumulation problem caused by poor drainage. When external dust, rainwater, etc. attempt to enter the room through the drain hole 2, due to the reverse resistance of the one-way channel 33, these impurities are effectively blocked outside, keeping the room clean and dry. The direction from the water inlet 34 to the water outlet 35 is the forward direction of the Tesla valves forming the one-way channel 33. When rainwater enters the inside of the one-way channel 33 through the water inlet 34 and flows, the fluid is divided into two streams at each intersection, and then these two streams of fluid will converge again at the next intersection, thus achieving an acceleration effect. When flowing reversely in the one-way channel 33, the backflow resistance gradually increases, thus realizing one-way diversion. The bottom surface of the cover plate 31 is in flat contact with the window frame 1. The number of the screws 32 is multiple. The cover plate 31 can be firmly attached to the window frame 1 under the fastening of multiple screws 32, and the sealing performance at the connection between the one-way channel 33 and the window frame 1 is ensured as much as possible. The number of the drain holes 2 is two and they are respectively opened at both ends of the side of the window frame 1. The two groups of drain holes 2 and the matching hydrophobic components 3 can effectively collect and drain the accumulated water in the window frame 1. The water outlet 35 is of an L-shaped structure. The port of the water outlet 35 is in flat contact with the drain hole 2. The water body in the one-way channel 33 can be smoothly drained through the water outlet 35 and the drain hole 2. A counterbore 37 for inserting the screw 32 is opened on the cover plate 31. A sealing ring 36 is installed inside the counterbore 37. After being squeezed by the cover plate 31 and the window frame 1, the sealing ring 36 undergoes elastic deformation, thus effectively avoiding the screw holes opened on the window frame 1.

[0031] The working principle of this technical solution is as follows: Align the L-shaped water outlet 35 with the drain hole 2, place the sealing ring 36 in the counterbore 37, and screw the screw 32 into the counterbore 37 and the screw holes opened on the window frame 1 to realize the stable installation of the hydrophobic component 3. After being squeezed by the cover plate 31 and the window frame 1, the sealing ring 36 undergoes elastic deformation, thus effectively avoiding the water inlet of the screw holes opened on the window frame 1. When rainwater accumulates in the window frame 1, the water body enters the one-way channel 33 of multiple Tesla valve types in the forward direction through the water inlet 34, accelerates the flow and then quickly drains to the outside through the water outlet 35 and the drain hole 2. When external dust, rainwater, etc. attempt to enter the room through the drain hole 2, due to the reverse resistance of the one-way channel 33, these impurities are effectively blocked outside, keeping the room clean and dry.
