Description

Technical Field

[0001] This utility model relates to the field of ventilation window technology, and in particular to an upward-exiting ventilation blade assembly and a ventilation window. Background Technology

[0002] To achieve better waterproofing and reduce water accumulation, current ventilation windows generally adopt a downward air outlet structure, where the blades are arched and the rear blades extend downwards to form a downward air outlet. This results in the air entering the ventilation window generally blowing towards the ground. Since the ventilation window is not installed high, the indoor equipment is not directly exposed to the cold air, resulting in poor ventilation and heat dissipation. Also, because hot air rises and cold air sinks, if the cold air enters from the bottom layer, the heat dissipation effect on the upper equipment is very poor, resulting in poor overall air exchange efficiency of the ventilation window.

[0038] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0039] The following is for reference. Figures 1 to 7 The present invention describes an upper-discharge ventilation blade assembly and ventilation window according to an embodiment of the present invention, wherein the airflow is set to flow from front to back.

[0040] like Figure 1 , Figure 2 As shown, the top-discharge ventilation blade assembly according to an embodiment of the present invention includes: at least two sets of blade groups 100 spaced apart in the front-to-back direction; each set of blade groups 100 includes a plurality of blades 110 spaced apart in the up-down direction.

[0041] The blade 110 has a V-shaped cross-section and includes a first plate 111 and a second plate 112 arranged sequentially along the front-back direction and forming an angle with each other. A V-shaped cavity 113 with an upward opening is formed between the first plate 111 and the second plate 112. An extension plate 114 is provided at the lower end of the first plate 111. A concave cavity 115 with a rearward opening is formed between the extension plate 114 and the second plate 112. The second plate 112 is provided with a drain hole 116 that can connect the V-shaped cavity 113 and the concave cavity 115.

[0042] A V-shaped air intake channel is formed between adjacent blades 110, causing the airflow delivered through the blade assembly to rise, achieving an upward airflow effect. By setting up a drain hole 116, water accumulation on the blades 110 is reduced. A rearward-facing concave cavity 115 is formed between the extension plate 114 and the second plate 112. The drain hole 116 is located on the second plate 112 and connects to the V-shaped cavity 113. When the airflow passes through the extension plate 114, a negative pressure is formed at the concave cavity 115 using the Venturi effect, making it easier for water accumulated in the V-shaped cavity 113 to flow downward through the drain hole 116, improving drainage efficiency and reducing water accumulation.

[0043] Specifically, due to the limited space of the blade 110, the drain hole 116 should not be set too large (otherwise it will cause air leakage and reduce the protective effect). Therefore, the drain hole 116 is more likely to prevent water from flowing downward due to the capillary effect. In this utility model, by setting the concave cavity 115 with the opening facing backward, when the airflow passes through the extension plate 114, the Venturi effect is used to form a negative pressure in the concave cavity 115. The drain hole 116 is set on the second plate 112, connecting the concave cavity 115 and the V-shaped cavity 113. When a negative pressure is formed in the concave cavity 115, the drain hole 116 can form a suction force on the water in the V-shaped cavity 113, so that the water in the V-shaped cavity 113 can more easily flow out through the drain hole 116, thereby improving the drainage efficiency and reducing the accumulation of scale or foreign matter in the drain hole 116 due to long-term water accumulation, thus improving the reliability of the drainage system.

[0044] like Figure 1 , Figure 2 As shown, in some embodiments of this utility model, the upper opening of the drain hole 116 is connected to the bottom of the V-shaped cavity 113 to drain the water accumulated at the bottom of the V-shaped cavity 113 as much as possible.

[0045] like Figure 2 As shown, in some embodiments of this utility model, in the same set of blade groups 100, a V-shaped air inlet channel is formed between adjacent blades 110. In two adjacent sets of blade groups 100, the outlet of the air inlet channel of one set of blade groups 100 corresponds to the inlet of the air inlet channel of the other set of blade groups 100, so as to improve the ventilation efficiency.

[0046] In some embodiments of this utility model, in the same set of blade groups 100, a V-shaped air inlet channel is formed between adjacent blades 110. In two adjacent sets of blade groups 100, the outlet of the air inlet channel of one set of blade groups 100 and the inlet of the air inlet channel of the other set of blade groups 100 are at least partially intersected, so that the airflow from one set of blade groups 100 to the other set of blade groups 100 is disturbed, thereby improving the protective isolation effect.

[0047] like Figure 1 As shown, in some embodiments of this utility model, the lower part of the extension plate 114 is provided with a protrusion 117, which corresponds to the position of the drain hole 116. The protrusion 117 guides the water flow to accumulate and fall at this location, and makes it easier for water droplets to fall into the drain hole 116 on the blade 110 below, thereby improving the drainage efficiency.

[0048] like Figure 7 As shown, in some embodiments of this utility model, a blocking part 118 is provided on the rear edge of the second plate 112. The blocking part 118 extends into the outlet of the V-shaped air inlet channel to block water in the discharged airflow and improve the protection effect.

[0049] Specifically, the blocking part 118 can be a vertical plate, an arc plate, an inclined plate, etc., all of which can achieve the desired blocking effect.

[0050] like Figure 7 As shown, in some embodiments of this utility model, the length h of the blocking part 118 extending into the V-shaped air inlet channel is less than 50% of the vertical width H (perpendicular to the airflow direction) of the V-shaped air inlet channel, that is, h < 0.5H, so as to avoid affecting the normal upward discharge of airflow.

[0051] Specifically, since the blocking part 118 is located at the rear edge of the second plate 112 and is relatively short, it is difficult to form an effective downward guiding air duct with the adjacent blades 110, thus having little impact on the upward airflow.

[0052] Reference Figures 3 to 6 According to a second aspect embodiment of the present invention, the ventilation window includes an upward-exhausting ventilation blade assembly and a frame assembly from any of the first aspects of the present invention. The frame assembly includes a first frame strip 210 and a second frame strip 220 distributed in the vertical direction, and a third frame strip 230 and a fourth frame strip 240 distributed in the horizontal direction. The first frame strip 210, the second frame strip 220, the third frame strip 230 and the fourth frame strip 240 enclose a square frame that can accommodate the upward-exhausting ventilation blade assembly, so as to facilitate the installation of the upward-exhausting ventilation blade assembly and form an upward-exhausting ventilation window, which has a better ventilation and heat dissipation effect on the equipment inside the ventilation window.

[0053] Specifically, the inner sides of the third frame strip 230 and the fourth frame strip 240 are respectively provided with mounting grooves corresponding to the blade assembly 100 to position the two ends of the blade 110. The frame assembly is used to install and cooperate with the corresponding mounting holes on the door or wall to fix the ventilation window to the door or wall.

[0054] like Figure 4 As shown, in some embodiments of this utility model, the bottom of the second frame strip 220 is provided with a drainage hole 221 to facilitate the drainage of water falling from the blade 110 and reduce water accumulation.

[0055] like Figures 3 to 6 As shown, in some embodiments of this utility model, the ventilation window further includes a fan assembly. The fan assembly includes a mounting plate 310 disposed on the rear side of the frame assembly and a plurality of fans 320 disposed on the mounting plate 310. By configuring the fan assembly, the ventilation efficiency can be improved.

[0056] like Figure 5 As shown, in some embodiments of this utility model, the rear sides of the third frame strip 230 and the rear sides of the fourth frame strip 240 are respectively provided with relatively distributed slots 311, the slots 311 correspond to the edges of the mounting plate 310, so that the mounting plate 310 can be inserted into the rear side of the frame assembly from top to bottom along the slots 311; the second frame strip 220 is provided with a support groove 312 for the lower edge of the mounting plate 310 to be inserted, so that the mounting plate 310 can be inserted into the rear side of the frame assembly from top to bottom, and the mounting plate 310 can be pulled out from bottom to top, which facilitates the installation of the fan assembly.

[0057] like Figure 5 As shown, in some embodiments of this utility model, the mounting plate 310 is provided with a handle 330 to facilitate the installation of the fan assembly.

[0058] It is understood that, in some embodiments of this utility model, the mounting plate 310 can also be mounted to the rear side of the frame assembly by screws, which will not be described in detail here.

[0059] like Figures 3 to 6 As shown, in some embodiments of this utility model, the lower two sides of the frame assembly are respectively provided with a pivot mechanism 400 that can be rotatably connected to the wall or door, and the upper or side of the frame assembly is provided with a locking mechanism 500 that can be connected to the wall or door. After the locking mechanism 500 is unlocked, the ventilation window can rotate around the pivot mechanism 400 to the outside of the wall or door, which not only facilitates the outdoor installation of the ventilation window, but also allows the ventilation window to be opened outdoors (the upper part of the ventilation window is flipped outward), which facilitates the assembly, disassembly and cleaning of the fan.

[0060] Specifically, after the locking mechanism 500 is unlocked, the ventilation window rotates around the rotating shaft mechanism 400 to the outside of the wall or door, causing the upper part of the ventilation window to flip to the outside. Operators can directly disassemble and clean the fan assembly from the outside, which facilitates the maintenance of the ventilation window.

[0061] like Figure 5 As shown, in some embodiments of this utility model, the rotating shaft mechanism 400 includes a mounting base 410 installed on the rear side of the second frame strip 220 and a pin 420 slidably disposed on the mounting base 410. The mounting base 410 is equipped with a spring 430 that can drive the pin 420 to extend elastically. During installation, the pin 420 is pressed inward. After the ventilation window is installed in the set position, the pin 420 is released. The pin 420 automatically inserts into the reserved shaft hole on the door or wall by the elastic force of the spring 430, so that the lower part of the ventilation window can be rotatably installed. Similarly, during disassembly, the pin 420 is pressed in.

[0062] Specifically, in this embodiment, the pivot mechanism 400 is similar to a door bolt mechanism, and the mounting base 410 is provided with a locking position corresponding to the pin 420 to facilitate the positioning of the pin 420.

[0063] Of course, in the specific implementation process, the pivot mechanism 400 can also be a pivot pin mechanism, which connects the ventilation window to the door / wall through screws with shaft shoulders, and can also realize the rotation installation function of the ventilation window.

[0064] like Figure 5 As shown, in some embodiments of this utility model, the locking mechanism 500 includes a rotating base 510 installed on the first frame strip 210, a lock cylinder 520 rotatably disposed on the rotating base 510, and a locking member 530 disposed on the lock cylinder 520. When the lock cylinder 520 rotates, it can drive the locking member 530 to rotate to the locking position or the unlocking position. When the locking member 530 rotates to the locking position, it can lock into the door or wall to fix the upper part of the ventilation window. When the locking member 530 rotates to the unlocking position, it can disengage from the corresponding locking position on the door or wall, so that the upper part of the ventilation window can rotate relative to its lower part, which is convenient and quick to use.

[0065] Specifically, the 520 lock cylinder is equipped with a keyhole and a corresponding key, providing a certain degree of anti-theft and anti-vandalism functionality.

[0066] It is understood that in some embodiments of this utility model, the locking mechanism 500 may also be a bolt mechanism, which locks or unlocks the upper part of the ventilation window by means of a bolt pin, which will not be described in detail here.

[0067] Of course, this invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
