Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to a self-contained louvered ventilator. Background Art

[0002] Ventilation, also known as air exchange, is the use of mechanical or natural methods to deliver sufficient fresh air into the indoor space, while expelling the dirty air that does not meet the hygiene requirements in the room, so that the indoor air meets the hygiene requirements and the needs of the production process.

[0003] At present, the conventional practice is to separate the ventilator and the air inlet louver, and reserve two holes in the room to install the ventilator and the air inlet louver respectively. However, too many holes will affect the integrity of the building structure wall and the aesthetics will be poor. In addition, since some rooms are small and can only have one hole, the ventilator can only be installed on the side wall, and the air inlet louver cannot be installed. The air can only enter through the door gap. In the long run, it will cause excessive negative pressure in the room, affecting the user's breathing experience, reducing the comfort of the room, and even affecting the opening of the room evacuation door. In addition, when the air outlet of the ventilator and the air inlet of the air inlet louver are too close, the dirty air that goes out through the ventilator outlet will directly enter the room through the air inlet louver, affecting the ventilation effect of the ventilator, and even affecting the air flow path, reducing the ventilation efficiency of the ventilator.

[0030] Such as Figure 1 and Figure 2As shown in the figure, this embodiment provides a built-in louver type ventilator, which includes a housing 1, a louver assembly 2, a ventilation assembly 3 and a flow deflector 4. Inside the housing 1, an air inlet chamber 11 and a ventilation chamber 12 are sequentially arranged from top to bottom. The louver assembly 2 is arranged at opposite ends of the air inlet chamber 11 along the first horizontal direction. A first through hole is formed in the louver assembly 2, and the air inlet chamber 11 is communicated with the outside through the first through hole. The ventilation assembly 3 is arranged in the ventilation chamber 12 and includes a ventilation driver 31 and a ventilation member 32. The ventilation driver 31 can drive the ventilation member 32 to rotate around the first horizontal direction. Second through holes are arranged at opposite ends of the ventilation chamber 12 along the first horizontal direction, and the ventilation chamber 12 is communicated with the outside through the second through holes. The flow deflector 4 is connected to the housing 1 and is arranged between the first through hole and the second through hole.

[0031] In this embodiment, the air inlet chamber 11 and the ventilation chamber 12 are sequentially arranged from top to bottom inside the housing 1, so that the air inlet and ventilation processes are separated from each other, which is beneficial to optimizing the air flow path, reducing air mixing and improving ventilation efficiency. The louver assembly 2 is arranged at opposite ends of the air inlet chamber 11 along the first horizontal direction. A first through hole is formed in the louver assembly 2, and the air inlet chamber 11 is communicated with the outside through the first through hole, so that the outside air can smoothly enter the air inlet chamber 11, which can not only ensure that there is sufficient fresh air in the room, but also ensure that the ventilation assembly 3 smoothly extracts gas from the room and discharges it to the outside. At the same time, by setting the louver assembly 2, sundries can be prevented from entering the air inlet chamber 11 to a certain extent, ensuring the smooth progress of the ventilation operation. The ventilation assembly 3 is arranged in the ventilation chamber 12 and includes a ventilation driver 31 and a ventilation member 32. The ventilation driver 31 can drive the ventilation member 32 to rotate around the first horizontal direction, thereby generating a strong air flow and effectively discharging the polluted air in the room. Second through holes are arranged at opposite ends of the ventilation chamber 12 along the first horizontal direction, and the ventilation chamber 12 is communicated with the outside through the second through holes to ensure the smoothness of the air flow path and ensure the normal operation of the ventilation assembly 3. The flow deflector 4 is connected to the housing 1 and is arranged between the first through hole and the second through hole, thereby isolating the direct air flow exchange between the air inlet chamber 11 and the ventilation chamber 12, preventing the polluted air discharged through the second through hole from directly entering the room through the first through hole, not only improving the ventilation effect, ensuring the indoor air quality, but also optimizing the air flow path and improving the ventilation efficiency. Through the above settings, the built-in louver type ventilator of this embodiment can integrate the louver assembly 2 and the ventilation assembly 3 into one body, which is convenient for installation and use and improves the ventilation quality and efficiency.

[0032] The specific structure of the built-in louver type ventilator will be described below:

[0033] Specifically, as Figure 2As shown in the figure, a partition 13 is provided inside the housing 1. The partition 13 is arranged between the air inlet chamber 11 and the ventilation chamber 12, which can isolate the air inlet chamber 11 and the ventilation chamber 12 from each other, avoiding direct air flow exchange between the two, ensuring that fresh air is introduced into the air inlet chamber 11, while the ventilation chamber 12 is used to discharge dirty air, thus optimizing the air flow path.

[0034] More specifically, as Figure 1 shown, the louver assembly 2 includes a plurality of louver blades 21. The plurality of louver blades 21 are sequentially arranged at intervals along the vertical direction on the housing 1, which helps to optimize the air flow path. At the same time, by arranging a plurality of louver blades 21, it can prevent debris such as large particles from entering and improve the ventilation effect. A first through hole is formed between two adjacent louver blades 21, enabling external air to smoothly enter the air inlet chamber 11 through the first through hole.

[0035] Specifically, as Figure 2 shown, the output end of the ventilation driver 31 is connected to the ventilation member 32, which can drive the ventilation member 32 to rotate, ensuring the high efficiency and accuracy of power transmission. When the ventilation driver 31 is started, it can quickly convert electrical energy or mechanical energy into rotational power and directly transmit it to the ventilation member 32 through the output end. When the ventilation driver 31 is not started or damaged, the indoor air can be exchanged through the louver assembly 2, avoiding the user from having difficulty breathing or even falling into a coma due to excessive carbon dioxide concentration in the room.

[0036] More specifically, as Figure 1 and Figure 2 shown, in this embodiment, the ventilation member 32 includes a rotating shaft 321 and a plurality of fan blades 322. The rotating shaft 321 extends along the first horizontal direction, and the plurality of fan blades 322 are arranged at intervals along the circumference of the rotating shaft 321. The ventilation driver 31 includes a motor, and the output shaft of the motor is connected to the rotating shaft 321, which can drive the rotating shaft 321 to rotate around its own axis. As the rotating shaft 321 rotates, the fan blades 322 start to cut the surrounding air and generate a forward air flow. These air flows converge in the ventilation chamber 12 and form a certain wind speed and flow rate, and finally are discharged outdoors through the second through hole. Among them, the ventilation driver 31 includes a stepper motor or a servo motor to ensure the stable operation of the fan blades 322, that is, the specific structure of the motor is not overly limited as long as it can achieve the above functions.

[0037] Even more specifically, in other embodiments, the ventilation member 32 further includes a rotating disk and a plurality of impellers. The plurality of impellers are arranged at intervals along the circumference of the rotating disk. The rotating disk is driven by a motor to rotate around the first horizontal direction, and then drives the impellers to rotate to achieve ventilation. It can be understood that the specific structure of the ventilation member 32 is not limited as long as it can achieve the above functions.

[0038] Specifically, among the two second through-holes, one second through-hole is configured as the air outlet end of the ventilation cavity 12, and the other second through-hole is configured as the air inlet end of the ventilation cavity 12. The air outlet end faces the outside, and the air inlet end faces the inside. When the fan blade 322 rotates to generate an air flow, the air in the ventilation cavity 12 is pushed towards the air outlet end and discharged outside through the second through-hole. During this process, to ensure the normal operation of the ventilation component 3, fresh air outside enters the room through the first through-hole on the louver component 2. When the fan blade 322 rotates to generate a negative pressure in the ventilation cavity 12, the polluted air in the room enters the ventilation cavity 12 through the air inlet end and is then discharged through the air outlet end, thereby realizing the circulation and renewal of the indoor air.

[0039] More specifically, the ventilation rate of the louver component 2 near the air outlet end is less than that of the louver component 2 near the air inlet end, that is, the density of the louver component 2 near the air outlet end is greater than that of the louver component 2 near the air inlet end. On the one hand, through the above setting, the exhaust air volume is slightly larger than the intake air volume, the air disturbance in the room is strengthened, and the gas circulates and flows, which is beneficial to discharging the turbid air and introducing fresh air. On the other hand, it can ensure that the louver component 2 near the air outlet end plays a certain shielding role to prevent rainwater from entering the air inlet cavity 11.

[0040] Specifically, the self - contained louvered ventilator further includes a filter screen, which is arranged on the louver component 2 to filter the air entering the air inlet cavity 11 and the room, preventing large - particle substances such as flying insects and soil particles from entering to ensure the ventilation effect.

[0041] Specifically, as Figure 2 shown, the flow - dividing plate 4 extends downward along the direction away from the housing 1. It can not only effectively guide the air flow, improve the air flow path, and prevent the polluted air discharged through the second through - hole from directly entering the room through the first through - hole. Moreover, by arranging the flow - dividing plate 4 between the air inlet cavity 11 and the ventilation cavity 12, it can play a certain rain - shielding role to prevent rainwater from eroding the ventilation component 3 in the ventilation cavity 12.

[0042] More specifically, the flow - dividing plate 4 is detachably connected to the housing 1 to facilitate the user to disassemble and maintain the flow - dividing plate 4. Among them, the detachable connection between the above - mentioned components can adopt methods such as screwing or clamping, and no more limitations are made here.

[0043] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
