Description

Technical Field

[0001] The present invention relates to the technical field of air guiding devices, and particularly relates to a window-mounted natural wind guiding component and a using method thereof. Background Art

[0002] Due to the relatively high air flow speed at high altitudes in high-rise residential buildings, when the window is normally opened, since there is no obstruction at the window opening, when the air flow enters the room through the window opening, it will still maintain a relatively high air flow speed.

[0003] In the way of direct blowing of high-speed air flow, the air flow will be relatively concentrated in a certain direction. The concentrated high-speed air flow will cause a poor body feeling for the residents in the residence, and at the same time, it will also cause a decrease in the complete circulation speed of the air flow in the room. For this reason, a window-mounted natural wind guiding component and a using method thereof are proposed. Summary of the Invention

[0004] In order to solve the above technical problems existing in the prior art, the present invention provides a window-mounted natural wind guiding component and a using method thereof.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A window-mounted natural wind guiding component, including a follow-up connection component, a wind guiding plate, and a movable angle limiting component for the wind guiding blades;

[0006] There are two groups of the follow-up connection components, and the two groups of the follow-up connection components are respectively installed on the outer window frame and the inner window frame surfaces of the window;

[0007] There are several groups of the wind guiding plates, and the several groups of the wind guiding plates are connected to each other to form a wind guiding plate group. Both ends of the wind guiding plate group are respectively connected to the two groups of the follow-up connection components. The wind guiding plate includes two groups of cross frames arranged up and down and a wind guiding plate with a rotating shaft arranged between the two groups of cross frames;

[0008] The movable angle limiting component for the wind guiding blades is installed at the end of the cross frame. The movable angle limiting component for the wind guiding blades is engaged with the end of the wind guiding plate, and the movable angle limiting component for the wind guiding blades limits the rotatable angle of the wind guiding plate.

[0009] Preferably, the follow-up connection component includes a metal tube, a connection joint, and a cross connection plate. The metal tube is a hollow tube. There are two groups of both the connection joint and the cross connection plate. The two groups of the connection joints are respectively installed outside both ends of the metal tube. The cross connection plate is installed inside the connection joint through a rotating shaft. The cross frame is connected to the cross connection plate through a rotating shaft.

[0010] Preferably, the follow-up connection assembly further includes connection hooks, hook springs and window attachment connection seats. There are two sets of connection hooks, and the two sets of connection hooks are respectively sleeved inside both ends of the metal tube. The hook springs are arranged inside the metal tube, and both ends of the hook springs are respectively connected to the two sets of connection hooks. The window attachment connection seat is arranged between the two sets of connection hooks.

[0011] Preferably, the cross-frame includes an upper rod and a lower rod. The centers of the upper rod and the lower rod are connected by a hollow rotating shaft. The air guide plate is installed inside the hollow rotating shafts of the two sets of cross-frames. The air guide plate is supported by the two sets of cross-frames. One side of the upper rod and the lower rod is connected to the cross-connecting plate through a rotating shaft, and the other side of the upper rod and the lower rod is connected to one side of another set of upper rod and lower rod through a rotating shaft.

[0012] Preferably, rotation limiting shafts are formed at the central positions of the top and bottom of the air guide plate. The rotation limiting shafts at the top and bottom of the air guide plate are respectively nested inside the hollow rotating shafts of the upper and lower two sets of cross-frames. A number of limiting notch openings for cooperation in limiting are formed at the ends of the rotation limiting shafts.

[0013] Preferably, through holes are formed at both ends of the middle part of the air guide plate, and an elastic binding band is commonly connected inside the through holes on the same side of a number of air guide plates.

[0014] Preferably, the movable angle limiting assembly of the air guide blades is sleeved outside the rotation limiting shaft. The movable angle limiting assembly of the air guide blades includes a fixed base, a limiting cover and a limiting baffle. The fixed base is installed outside the hollow rotating shaft of the cross-frame. The limiting cover is sleeved outside the fixed base and is snap-connected to the fixed base. The limiting baffle is formed on the inner wall of the fixed base, and the limiting baffle is placed inside the limiting notch opening of the rotation limiting shaft.

[0015] Preferably, the opening direction of the limiting notch opening of the rotation limiting shaft is consistent with both ends of the air guide plate, and the opening angle of the limiting notch opening is 90°.

[0016] The usage method of the window-following natural wind guiding assembly includes the following steps:

[0017] Step A, install the device between the outer window frame and the inner window frame of the window;

[0018] Step B, set the movable angle limiting assembly of the air guide blades according to the opening method of the window;

[0019] Step C, open the window, and the device unfolds as the window is opened.

[0020] Preferably, the said Step A includes,

[0021] Step A1: Set the window to the closed state, and fix the two sets of auxiliary window connection seats at the same height on the same side of the outer window frame and the inner window frame of the window in the closed state.

[0022] Step A2: Connect the two sets of follower connection components to the two sets of auxiliary window connection seats respectively. Pull the connection hook at one end of the metal tube in a set of follower connection components to move the connection hook vertically along the metal tube, embed the end of the connection hook at the other end into one end of a set of auxiliary window connection seats. Align the pulled connection hook with one end of the auxiliary window connection seat, release the pull on the pulled connection hook, and let the connection hook retract along the metal tube again under the elastic force of the hook spring. The end of the connection hook is embedded into the other end of the auxiliary window connection seat during the retraction process to complete the connection. Similarly, repeat the above steps to connect the other set of follower connection components to the other set of auxiliary window connection seats.

[0023] Step B includes:

[0024] Step B1: For a horizontally sliding window, set the limit baffle in the limit cover at the middle position of the limit slot of the rotating limit shaft. The rotating limit shaft cooperates with the limit baffle, and the movable angle of the rotating limit shaft relative to the limit baffle is ±45°.

[0025] Step B2: For a side-sliding window, set the limit baffle in the limit cover at the side of the limit slot of the rotating limit shaft. The rotating limit shaft cooperates with the limit baffle, and the movable angle of the rotating limit shaft relative to the limit baffle is ±90°.

[0026] Step C includes:

[0027] Step C1: The metal tube that moves with the inner window frame drives the connection joint and the cross connection plate to move synchronously.

[0028] Step C2: Under the pull of the cross connection plate, the cross frame is subjected to a lateral pulling force. During the force-bearing process of the cross frame, the upper rod and the lower rod rotate and open relative to the hollow rotating shaft. After opening, there is a certain distance between each group of cross frames, and the wind guide plates arranged between the cross frames open with the cross frames.

[0029] Step C3: Several groups of wind guide plates open synchronously with the expansion of the cross frames. The elastic binding straps are gradually straightened and tightened under the pull of the wind guide plates. Under the pull of the elastic binding straps, several groups of wind guide plates maintain the same orientation.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. The present invention is provided with a follow-up connection component and a movable angle limit component for the air guide vane. The air guide vane can reduce the wind speed of the passing air flow, and the movable angle limit component can limit the movable angle of the air guide vane, enabling the air guide plate to be maintained within a limited angle according to the outdoor wind direction and wind speed. After the air flow passes through the air guide vane, the air flow velocity slows down, reducing the problem of poor physical sensation caused by the direct blowing of high-speed air flow. At the same time, after the wind speed decreases, the speed of the air flow completely circulating in the room is correspondingly increased.

[0032] 2. By setting a metal pipe connection joint, a cross connection plate, a connection hook, a hook spring, and a window attachment connection seat, the present invention can be adapted to both side-opening sliding windows and casement windows in a split connection manner. When the window is opened, it unfolds synchronously with the window. When the window is closed, it retracts to one side of the window wall with the window, reducing the occupied space.

[0048] The following further elaborates the present invention in combination with the accompanying drawings and embodiments on the above and other technical features and advantages of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them.

[0049] Embodiment:

[0050] As Figures 1 - 3 shown, the present invention provides a window-following natural wind guiding component, including a follow-up connection assembly 1, an air deflector 3, and a movable angle limit assembly 4 for air guide vanes;

[0051] Two groups of follow-up connection assemblies 1 are provided, and the two groups of follow-up connection assemblies 1 are respectively installed on the surfaces of the outer window frame and the inner window frame of the window;

[0052] A number of groups of air deflectors 3 are provided, and the several groups of air deflectors 3 are connected to form an air deflector group. Both ends of the air deflector group are respectively connected to the two groups of follow-up connection assemblies 1. The air deflector 3 includes two groups of cross frames 2 arranged up and down and an air deflector 3 with a rotating shaft arranged between the two groups of cross frames 2;

[0053] The movable angle limit assembly 4 for air guide vanes is installed at the end of the cross frame 2. The movable angle limit assembly 4 for air guide vanes is engaged with the end of the air deflector 3, and the movable angle limit assembly 4 for air guide vanes limits the rotatable angle of the air deflector 3.

[0054] The follow-up connection assembly 1 includes a metal tube 11, a connection joint 12, and a cross connection plate 13;

[0055] The metal pipe 11 is a hollow pipe. There are two sets of connecting joints 12 and cross connecting plates 13. The two sets of connecting joints 12 are respectively installed on the outer parts of both ends of the metal pipe 11. The cross connecting plate 13 is installed inside the connecting joint 12 through a rotating shaft. The cross frame 2 is connected to the cross connecting plate 13 through a rotating shaft. The metal pipes 11 of the two sets of follow-up connecting components 1 are respectively connected to the surfaces of the outer window frame and the inner window frame of the window. When the inner window frame is opened, it drives the metal pipe 11 to move, and the metal pipe 11 synchronously drives the connecting joint 12 and the cross connecting plate 13 to move.

[0056] The cross frame 2 includes an upper rod 21 and a lower rod 22;

[0057] The centers of the upper rod 21 and the lower rod 22 are connected by a hollow rotating shaft. The air guiding plate 3 is installed inside the hollow rotating shafts of the two sets of cross frames 2. The air guiding plate 3 supports the two sets of cross frames 2. One side of the upper rod 21 and the lower rod 22 is connected to the cross connecting plate 13 through a rotating shaft. The other side of the upper rod 21 and the lower rod 22 is connected to one side of another set of upper rod 21 and lower rod 22 through a rotating shaft. Under the pulling of the cross connecting plates 13 on both sides, the cross frame 2 is subjected to a lateral pulling force. During the force application process, the upper rod 21 and the lower rod 22 rotate and open relative to the hollow rotating shaft. A certain distance is maintained between each set of opened cross frames 2. The air guiding plate 3 arranged between the cross frames 2 opens with the cross frame 2.

[0058] Rotating limit shafts 31 are formed at the central positions of the top and bottom of the air guiding plate 3. The rotating limit shafts 31 at the top and bottom of the air guiding plate 3 are respectively nested inside the hollow rotating shafts of the upper and lower two sets of cross frames 2. During the opening process of the upper and lower two sets of cross frames 2, the air guiding plate 3 is driven to move synchronously through the rotating limit shafts 31. A number of sets of air guiding plates 3 are synchronously unfolded with the opening of the cross frame 2. A number of sets of limiting notch openings for cooperation are provided at the ends of the rotating limit shafts 31. The opening direction of the limiting notch openings of the rotating limit shafts 31 is consistent with both ends of the air guiding plate 3. The opening angle of the limiting notch openings is 90°.

[0059] Through holes are provided at both ends in the middle of the air guiding plate 3. A set of elastic straps 32 are commonly connected inside the through holes on the same side of a number of sets of air guiding plates 3. When a number of sets of air guiding plates 3 are synchronously opened with the unfolding of the cross frame 2, the elastic straps 32 are gradually straightened and tightened under the pulling of the air guiding plates 3. Under the pulling of the elastic straps 32, a number of sets of air guiding plates 3 that open with the cross frame 2 maintain the same orientation. When encountering air flow, due to the stretchable property of the elastic straps 32, adjacent two sets of air guiding plates 3 can rotate to different degrees according to the wind receiving situation. Between adjacent two sets of elastic straps 32, the different degrees of deflection of the adjacent air guiding plates 3 are adapted through stretching to adapt to sudden increases in wind speed, wind speed changes, and turbulent flows. After the wind speed decreases, the elastic straps 32 can retract through elastic force to make the air guiding plates 3 return to the initial state, and all sets of air guiding plates 3 maintain the same deflection angle.

[0060] The movable angle limiting assembly 4 of the air guide vane is sleeved outside the rotation limiting shaft 31. The movable angle limiting assembly 4 of the air guide vane includes a fixed base 41, a limiting cover 42 and a limiting baffle 43;

[0061] The fixed base 41 is installed outside the hollow rotating shaft of the cross-frame 2. The limiting cover 42 is sleeved outside the fixed base 41 and is snap-connected to the fixed base 41. After the limiting baffle 43 is snap-connected to the fixed base 41, the relative positions of the limiting cover 42 and the fixed base 41 are fixed. The limiting baffle 43 is formed on the inner wall of the fixed base 41. The limiting baffle 43 is placed in the limiting notch of the air guide plate 3. When the limiting cover 42 is in a fixed setting state, the setting angle of the limiting baffle 43 is fixed. In the fixed state, the movable angle of the rotation limiting shaft 31 is restricted by the limiting baffle 43. Therefore, the movable angle of the air guide plate 3 is also restricted. The air guide plate 3 swings within a certain range within the area restricted by the limiting cover 42.

[0062] The follow-up connection assembly 1 further includes a connection hook 14, a hook spring 15 and an attached window connection seat 16;

[0063] There are two sets of connection hooks 14. The two sets of connection hooks 14 are respectively sleeved inside the two ends of the metal tube 11. The hook spring 15 is arranged inside the metal tube 11. The two ends of the hook spring 15 are respectively connected to the two sets of connection hooks 14. Under the elastic force of the hook spring 15, the two sets of connection hooks 14 are pulled closer and stored inside the metal tube 11. By pulling, the connection hook 14 can be horizontally moved along the metal tube 11, so as to expand the distance between the two sets of connection hooks 14 for connection during installation. The attached window connection seat 16 is arranged between the two sets of connection hooks 14. The attached window connection seat 16 is used to adhere to the surface of the inner window frame or the outer window frame. The attached window connection seat 16 that fits with the surface of the inner window frame or the outer window frame is used to connect with the connection hook 14. During connection, pull one end of the connection hook 14 to make the connection hook 14 vertically move along the metal tube 11, embed the end of the other connection hook 14 into one end of the attached window connection seat 16. Align the pulled connection hook 14 with one end of the attached window connection seat 16, release the pulling of the pulled connection hook 14, and make the connection hook 14 retract along the metal tube 11 again under the elastic force of the hook spring 15. The end of the connection hook 14 is embedded into the other end of the attached window connection seat 16 during the retraction process to complete the connection.

[0064] Such as Figure 4 and Figure 5As shown in the figure, a feasibility verification is carried out through simulation. The PHOENICS software is used for the feasibility verification. The northeast wind and the southeast wind are selected. The wind speeds in different indoor areas are simulated respectively under the conditions of 10 m / s without the window-mounted natural wind guiding component and 10 m / s with the window-mounted natural wind guiding component. It can be seen from the simulation results that the indoor wind speed with the window-mounted natural wind guiding component is significantly lower than that without the window-mounted natural wind guiding component, and there is air flow in each room with the window-mounted natural wind guiding component, which means natural ventilation is carried out indoors;

[0065] As Figures 6 - 13 shown, a numerical simulation analysis of natural ventilation under the condition of adding the window-mounted natural wind guiding component is carried out. Through the computational fluid dynamics (CFD) simulation method, a corresponding table of the relationship between the time required for the indoor air to be replaced once and the opening angle of the air guiding plate at different wind speeds in the southeast wind environment is obtained:

[0066] Table 1. Corresponding table of the relationship between the time required for the indoor air to be replaced once and the opening angle of the air guiding plate at different wind speeds

[0067] Wind speed 10 m / s 9 m / s 8 m / s 7 m / s 6 m / s Opening angle 90° 90° 90° 90° 90° Ventilation time 80s 75s 70s 63s 60s Opening angle 60° 60° 60° 60° 60° Ventilation time 80s 73s 69s 64s 59s Opening angle 30° 30° 30° 30° 30° Ventilation time 78s 75s 70s 62s 60s

[0068] It can be seen from the analysis of the data in Table 1 that the optimal indoor ventilation speed is achieved when the movable range of the air guiding plate 3 is maintained within the range of ±30° to ±90°;

[0069] Therefore, after the window-mounted natural wind guiding component is set, the movable angle position of the air guiding plate is restricted to be maintained within the range of ±30° to ±90° by adjusting the movable angle limiting component of the air guiding blade.

[0070] The above description is only a preferred embodiment of the present invention, which is illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
