Description

Technical Field

[0001] The present invention belongs to the technical field of energy-saving ventilation, and particularly relates to an energy-saving building ventilation device. Background Art

[0002] With the continuous development of the economy, the scale of current buildings is getting larger and larger. Since the exterior walls of current buildings use glass and curtain walls, and for safety reasons, the window area in building design is limited, and the windows are basically in a closed state during use. Therefore, the natural ventilation effect of modern buildings is relatively low, and it is not easy to achieve natural ventilation.

[0003] In addition, when the windows of a building use casement windows and sliding windows for ventilation, rainwater is easily blown into the room by the wind, resulting in rain leakage, and it is not suitable for natural ventilation on hot and humid rainy days; when using outward-opening windows for ventilation, the outward-opening windows are pushed open from the lower part, creating a gap, and the window opening faces downward, which can avoid rain leakage to a certain extent on rainy days, but the wind is not easily blown in, and the actual natural ventilation effect is relatively poor. Other ventilation methods using ventilation equipment consume a large amount of electric energy, which is not conducive to energy conservation, emission reduction, and green development. Summary of the Invention

[0004] In order to solve the deficiencies mentioned in the above prior art, the present invention provides an energy-saving building ventilation device.

[0005] The present application proposes an energy-saving building ventilation device, which includes a window frame. The upper inner wall of the top end of the window frame is movably installed with an upper-hung window through a hinge, and the lower inner wall of the window frame is installed with an auxiliary frame having a telescopic function.

[0006] Specifically, the auxiliary frame includes a fixed frame and a movable frame. The bottom end of the fixed frame is fixedly installed on the lower inner wall of the window frame. A placement groove is opened on the top surface of the fixed frame, and a control component is arranged in the fixed frame. The control component can control the movable frame to be inserted into the placement groove.

[0007] Specifically, the control component includes two long strip blocks, which are respectively fixedly installed on both sides of the movable frame. A threaded hole is opened at the bottom end of the long strip block. A long strip groove is opened inside the bottom end of the window frame. The inner walls of the bottom ends on both sides of the long strip groove are respectively movably installed with screw rods. The top end of the screw rod passes through the bottom end of the fixed frame, and the top end of the screw rod can be inserted into the threaded hole. The two screw rods are connected by a connecting piece. An adjusting piece is installed at the bottom end of the window frame, and the adjusting piece can control the screw rod to rotate.

[0008] Specifically, the connecting piece includes two sprockets, which are fixedly installed at the bottom ends of the screw rods, and the two sprockets are movably connected by a chain.

[0009] Specifically, the adjusting member includes a groove formed at the bottom end of the front of the window frame. The rear end of the groove communicates with the inside of the long slot. A rotating rod is installed in the groove by a bearing, and a first bevel gear is fixedly installed at the rear end of the rotating rod. A second bevel gear is fixedly installed at the bottom end of one of the screw rods, and the second bevel gear can be engaged with the first bevel gear.

[0010] Specifically, a fixing block is fixedly installed at the front of the bottom end of the window frame. A jack is formed at the top end of the fixing block, and a T-shaped plug rod is slidably installed in the jack. A through hole is formed on the top surface of the rotating rod, and the vertical rod of the T-shaped plug rod can be inserted into the through hole.

[0011] Compared with the prior art, the present invention has the following beneficial effects: When the top-hung window is closed, it contacts the top end of the auxiliary frame in the extended state. When ventilation is required on a sunny day, the top-hung window is pushed outwards to open, and the hinge fixes the top-hung window. There is a gap between the top-hung window and the auxiliary frame for ventilation. When better ventilation effect is needed, the auxiliary frame contracts, and the distance between the top end of the auxiliary frame and the top-hung window becomes larger, that is, the gap increases, and more air volume can enter; when ventilation is required on a rainy day, the top-hung window is pushed outwards to open, and the wind enters the room through the gap between the top-hung window and the auxiliary frame. When more air volume is needed, the auxiliary frame contracts, and the gap between the auxiliary frame and the top-hung window becomes larger, and more wind can enter the room. Moreover, due to the function of the top-hung window, rainwater can be prevented from entering the room; through the present application, the ventilation opening area can be increased during ventilation, so that more wind can enter the room. Moreover, on rainy days, ventilation can also be carried out through operation, and the air volume can also be adjusted, and the effect of natural ventilation can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the following drawings are some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0013] Figure 1 is a schematic structural diagram of the present invention; Figure 2 is a use state diagram in the side view direction of the present invention; Figure 3 is Figure 2 a partial enlarged view of A of Figure 4 is Figure 2 a partial enlarged view of B of DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0015] An energy-saving building ventilation device, as Figures 1-4 shown, includes a window frame 1. The inner wall of the top end of the window frame 1 is movably installed with an upper-hung window 2 through a hinge. The inner wall of the bottom end of the window frame 1 is installed with an auxiliary frame 3 with a telescopic function. The connection relationship and installation method of the upper-hung window 2 and the hinge are prior arts, so no detailed description will be given here. The upper-hung window is pushed outwards to open in the existing manner.

[0016] When the upper-hung window 2 is closed, it contacts the top end of the extended auxiliary frame 3. When ventilation is required on a sunny day, the upper-hung window 2 is pushed outwards to open, and the hinge fixes the upper-hung window. There is a gap between the upper-hung window 2 and the auxiliary frame 3 for ventilation. When a better ventilation effect is needed, the auxiliary frame 3 contracts, and the distance between the top end of the auxiliary frame 3 and the upper-hung window 2 becomes larger, that is, the gap increases, and more air volume can enter. When ventilation is required on a rainy day, the upper-hung window 2 is pushed outwards to open, and the wind enters the house through the gap between the upper-hung window 2 and the auxiliary frame 3. When it is necessary to increase the air volume, the auxiliary frame 3 contracts, and the gap between the auxiliary frame 3 and the upper-hung window 2 becomes larger, and more wind can enter the house. Moreover, due to the function of the upper-hung window 2, rainwater can be prevented from entering the house. Through this application, the ventilation opening area can be increased during the ventilation process, so that more wind can enter the house. Moreover, on rainy days, ventilation can also be achieved through operation, and the air volume can also be adjusted, and the effect of natural ventilation can be realized.

[0017] Specifically, the auxiliary frame 3 described in this embodiment includes a fixed frame 4 and a movable frame 5. The bottom end of the fixed frame 4 is fixedly installed on the inner wall of the bottom end of the window frame 1. A placement groove 6 is formed on the top surface of the fixed frame 4. A control component is arranged in the fixed frame 4, and the control component can control the movable frame 5 to be inserted into the placement groove 6.

[0018] Glass is fixedly installed both inside the fixed frame 4 and inside the movable frame 5. A drain hole is opened on the inner wall at the rear bottom end of the placement groove 6. Some of the rainwater blown into the placement groove 6 by the wind during rainy days is discharged under the action of the drain hole. The movable frame 5 is moved out of the placement groove 6 under the control of the control assembly. The top end of the movable frame 5 can contact the bottom surface of the casement window 2 in the closed state. At this time, the window frame 1 is blocked, and there is no gas exchange between the interior and the outside. When only the casement window 2 is opened, ventilation is carried out through the gap between the casement window 2 and the movable frame 5. When it is necessary to increase the air volume, the control assembly controls the movable frame 5 to move downward. The movable frame 5 enters the placement groove 6. The length of the movable frame 5 entering the placement groove 6 determines the size of the gap between the movable frame 5 and the casement window 2, thereby controlling the change in the area of the ventilation opening and controlling the air intake volume.

[0019] Further, the control assembly described in this embodiment includes two long strip blocks 7. The two long strip blocks 7 are respectively fixedly installed on both sides of the movable frame 5. A threaded hole is opened at the bottom end of the long strip block 7. A long strip groove 8 is opened inside the bottom end of the window frame 1. The inner walls at the bottom ends on both sides of the long strip groove 8 are respectively movably installed with screw rods 9. The top end of the screw rod 9 passes through the bottom end of the fixed frame 4, and the top end of the screw rod 9 can be inserted into the threaded hole. The two screw rods 9 are connected through a connecting piece. An adjusting piece is installed at the bottom end of the window frame 1, and the adjusting piece can control the screw rod 9 to rotate.

[0020] The long strip block 7 can be inserted into the placement groove 6. The adjusting piece controls the screw rod 9 to rotate. Through the connection of the connecting piece, the two screw rods 9 rotate synchronously. The screw rod 9 is in threaded cooperation with the threaded hole, so that the two long strip blocks 7 can move upward or downward, driving the movable frame 5 to move up and down reciprocally, adjusting the height change of the movable frame 5, and performing ventilation operations with different air volumes.

[0021] Still further, the connecting piece described in this embodiment includes two sprockets 10. The sprockets 10 are fixedly installed at the bottom ends of the screw rods 9. The two sprockets 10 are movably connected through a chain. The sprockets 10 and the chain are located in the long strip groove 8. Through the connection of the sprockets 10 and the chain, the two screw rods 9 can rotate synchronously.

[0022] Still further, the adjusting piece described in this embodiment includes a groove 11 opened at the bottom end of the front end of the window frame 1. The rear end of the groove 11 communicates with the inside of the long strip groove 8. A rotating rod 12 is installed in the groove 11 by means of a bearing. A first bevel gear 13 is fixedly installed at the rear end of the rotating rod 12. A second bevel gear 14 is fixedly installed at the bottom end of one of the screw rods 9. The second bevel gear 14 can be meshed and matched with the first bevel gear 13.

[0023] The outer periphery of the rotating rod 12 is fixedly connected to the inner wall of the inner ring of the bearing, and the outer wall of the outer ring of the bearing is fixedly connected to the inner wall of the groove 11. Rotating the rotating rod 12 drives the first bevel gear 13 to rotate. The first bevel gear 13 is meshed with the second bevel gear 14, which can drive the screw rod 9 to rotate. Through the action of the connecting piece, the rotation of two screw rods 9 can be controlled simultaneously. The operation is simple. Only by controlling the rotation of the rotating rod 12 can the up-and-down movement of the moving frame 5 be controlled.

[0024] Furthermore, a fixing block 15 is fixedly installed on the front of the bottom end of the window frame 1 in this embodiment. A jack is opened at the top of the fixing block 15, and a T-shaped plug rod 16 is slidably installed in the jack. A through hole is opened on the top surface of the rotating rod 12, and the vertical rod of the T-shaped plug rod 16 can be inserted into the through hole.

[0025] The length of the horizontal rod of the T-shaped plug rod 16 is greater than the diameter of the jack. When the moving frame 5 does not need to be adjusted, the vertical rod of the T-shaped plug rod 16 passes through the fixing sleeve 15 and is inserted into the through hole. At this time, the rotating rod 12 cannot rotate for protection. When the rotating rod 12 needs to be rotated, only the T-shaped plug rod 16 needs to be taken out of the through hole.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
