Description

Technical Field

[0001] This utility model relates to the field of window sash technology, specifically to a window sash that facilitates two-way ventilation. Background Technology

[0002] Window sashes are typically installed on windows and are structurally divided into indoor and outdoor sections. Their main function is to introduce fresh outdoor air into the room, help lower the room temperature, and remove some heat through airflow.

[0003] A window sash with adjustable air intake direction, disclosed in CN215565574U, includes a housing, a fan rotatably disposed within the housing, and a rotary drive for driving the fan to rotate. The housing has an air inlet and an air outlet. An air control assembly is also provided within the housing. The air control assembly includes a mounting base rotatably connected to the housing, a guide plate and a cutter plate disposed on the mounting base, and an air control drive for driving the mounting base to rotate. The guide plate and cutter plate are located on the outer periphery of the fan and are used to guide the airflow. In the above device, the guide plate and cutter plate are both installed on the outer periphery of the fan. During the air intake process, especially during changes in wind speed, inlet turbulence may occur. Inlet turbulence refers to the disordered and irregular flow phenomenon of airflow entering the window sash, making it impossible for the airflow entering the window sash to be evenly distributed. The fan blades generate asymmetrical loads due to local velocity differences, which may cause vibration or accelerated wear. At the same time, turbulence increases airflow resistance, forcing the rotary drive to increase power to maintain the target airflow, resulting in increased motor load.

[0004] Therefore, it is necessary to invent a window sash that facilitates two-way ventilation to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a window sash that facilitates bidirectional ventilation, thus solving the problem of inlet turbulence that may occur when gas enters the casing during actual use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A window sash for facilitating bidirectional ventilation includes a rotating impeller body, a housing located outside the impeller body, and air vents on both sides of the housing. A drive assembly for rotating the impeller body is installed inside the housing. An air exchange assembly is located inside the housing, including a cutter assembly for dividing airflow and a guide plate for guiding gas. The drive assembly also includes impeller limiting plates located on both sides of the impeller body. The guide plates are detachably connected to the impeller limiting plates at both ends. The cutter assembly is fixedly installed inside the housing, and a smooth guide end face is provided at the end of the cutter assembly near the air vents.

[0008] As a preferred embodiment of this utility model, the housing includes a front shell, a rear shell, and a side cover. The air vents include an air vent one located at the upper half of the front shell and an air vent two located at the lower half of the rear shell. The air cutting assembly includes a front air cutting plate, a rear air cutting plate, a fixing block one, and a fixing block two. The front air cutting plate is fixedly connected to the front shell through the fixing block two, and the rear air cutting plate is fixedly connected to the rear shell through the fixing block one.

[0009] In a preferred embodiment of this utility model, the front air cutter is located at the bottom of the first air outlet, and the rear air cutter is located at the top of the second air outlet.

[0010] When the air guide plate is close to the front air cutter plate, the air outlet is the second air outlet;

[0011] When the air guide plate is close to the rear air cutter plate, the air outlet is the first air outlet.

[0012] In a preferred embodiment of this utility model, the drive assembly further includes a motor mounting base, a drive motor, an adjusting gear, and a drive gear. The side cover also includes a left side cover and a right side cover. The motor mounting base is fixedly installed on one side of the side cover. The drive motor is fixedly installed on the inner side of the motor mounting base. The output end of the drive motor is used to drive the wind turbine body to rotate. The adjusting gear is fixedly installed on the other end of the wind turbine limiting plate. A drive gear is provided on one side of the adjusting gear to drive the wind turbine limiting plate to rotate synchronously. A stepper motor is installed on the inner side of the motor mounting base, and the stepper motor is used to drive the drive gear to rotate.

[0013] In a preferred embodiment of this utility model, the drive component is disposed on one side of the left or right cover.

[0014] In a preferred embodiment of this utility model, the impeller limiting plate is rotatably connected to the motor mounting base, and the impeller limiting plate on the side away from the motor mounting base is rotatably connected to the side cover.

[0015] As a preferred embodiment of this utility model, a control module for controlling the drive assembly is detachably installed at the bottom of the inner side of the front shell.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] In this invention, by installing the air cutter plate inside the housing and setting a smooth guide end face on the side of the air cutter plate near the air outlet, the smooth surface of the air cutter plate can guide the airflow smoothly into the interior of the housing, avoiding turbulence at the entrance of the housing. By dividing or guiding the external airflow into the interior of the window sash, the uniformity and stability of the airflow are improved, avoiding excessively high local wind speeds or dead air zones. By optimizing the air outlets on both sides, local superimposed resistance is avoided, reducing fan energy consumption. By controlling the air guide plate to move closer to or further away from the corresponding air cutter plate, the airflow direction of the window sash can be switched, thereby achieving the switching of indoor or outdoor airflow direction and realizing the purpose of bidirectional ventilation.

[0024] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be construed as limiting the scope of protection of the present invention.

[0025] This utility model provides, for example Figure 1-5The window sash shown is designed for bidirectional ventilation. It includes a rotating impeller body 7, a housing located outside the impeller body 7, and air vents on both sides of the housing. A drive assembly 6 for rotating the impeller body 7 is installed inside the housing. An ventilation assembly is located inside the housing, including a cutter assembly 8 for dividing airflow and a guide plate 9 for guiding gas. The drive assembly 6 also includes impeller limiting plates 605 located on both sides of the impeller body 7. The guide plate 9 is detachably connected to the impeller limiting plates 605 at both ends. The cutter assembly 8 is fixedly installed inside the housing, and a smooth guide end face is provided at the end of the cutter assembly 8 near the air vents. The impeller limiting plates 605 at both ends are coaxially aligned with the impeller body 7, ensuring uniform force distribution during impeller rotation and avoiding eccentricity caused by misalignment, thereby reducing vibration and noise. The connection between the impeller limiting plates 605 on both sides and the guide plates 9 facilitates synchronous rotation of the impeller limiting plates 605 on both sides.

[0026] The housing includes a front shell 1, a rear shell 2, and side covers. The air vents include an air vent 101 located at the upper half of the front shell 1 and an air vent 201 located at the lower half of the rear shell 2. The air cutting assembly 8 includes a front air cutter 803, a rear air cutter 801, a fixing block 802, and a fixing block 804. The front air cutter 803 is fixedly connected to the front shell 1 via the fixing block 804, and the rear air cutter 801 is fixedly connected to the rear shell 2 via the fixing block 802. The air cutter configuration of the front and rear air cutters 803 and 801 ensures that turbulence can still be reduced after a change in wind direction.

[0027] The front air cutter 803 is located at the bottom of the air outlet 101, and the rear air cutter 801 is located at the top of the air outlet 201.

[0028] When the air guide plate 9 is close to the front air cutter plate 803, the air outlet is the second air outlet 201;

[0029] When the air guide plate 9 approaches the rear air cutter plate 801, the air outlet is air outlet 101. By setting the air cutter plate at the top or bottom of the air outlet, the airflow can be prevented from directly impacting the air cutter plate, thus affecting the airflow delivery, avoiding turbulence caused by vertical impact, and reducing local resistance.

[0030] The drive assembly 6 further includes a motor mounting base 601, a drive motor 602, an adjusting gear 603, and a drive gear 604. The side cover also includes a left side cover 3 and a right side cover 4. The motor mounting base 601 is fixedly installed on one side of the side cover. The drive motor 602 is fixedly installed on the inner side of the motor mounting base 601. The output end of the drive motor 602 is used to drive the wind turbine body 7 to rotate. The adjusting gear 603 is fixedly installed on the other end of the wind turbine limiting plate 605. A drive gear 604 is provided on one side of the adjusting gear 603 to drive the wind turbine limiting plate 605 to rotate synchronously. A stepper motor is installed on the inner side of the motor mounting base 601, and the stepper motor is used to drive the drive gear 604 to rotate. The output end of the drive motor 602 extends through the motor mounting base 601, through the adjusting gear 603 and the wind turbine limiting plate 605 to the inner side of the wind turbine body 7, and is fixed thereto by bolts.

[0031] The drive component 6 is located on one side of the left cover 3 or the right cover 4.

[0032] The impeller limiting plate 605 is rotatably connected to the motor mounting base 601, and the impeller limiting plate 605 on the side away from the motor mounting base 601 is rotatably connected to the side cover. The rotatable connection of the impeller limiting plates 605 ensures that the impeller limiting plates 605 on both sides can rotate synchronously, avoiding the impact of speed deviation on the rotation of the impeller and ensuring the stability of rotation.

[0033] A control module 5 for controlling the drive assembly 6 is detachably installed at the bottom of the inner side of the front housing 1. The control module 5 is used to control the speed of the drive motor 602 and to control the drive gear 604 to rotate via a stepper motor, thereby adjusting the position of the air guide plate 9.

[0034] This invention, by installing a wind-cutting plate inside the housing and providing a smooth guide surface on the side of the wind-cutting plate near the air outlet, can guide the airflow smoothly into the interior of the housing using the smooth surface of the wind-cutting plate, avoiding turbulence at the housing inlet. By dividing or guiding external airflow into the interior of the window sash, it improves the uniformity and stability of the airflow, avoiding excessively high local wind speeds or dead air zones. By optimizing the air outlets on both sides, it avoids localized resistance accumulation and reduces fan energy consumption. By controlling the air guide plate 9 to move closer to or further away from the corresponding wind-cutting plate, it can switch the airflow direction of the window sash, thereby achieving the switching of indoor or outdoor airflow direction and realizing bidirectional ventilation.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
