Description

Technical Field

[0001] The utility model relates to an intelligent door and window, in particular to an intelligent door and window with a ventilation function, and belongs to the technical field of doors and windows. Background Art

[0002] At present, the ventilation function of intelligent doors and windows has evolved from a single air exchange function to an integrated solution for environmental perception and energy management, but there are still obvious shortcomings in the ventilation and filtration link: the filter screen is fixedly installed, its cleaning completely relies on manual regular cleaning, and a self-cleaning mechanism is lacked. Meanwhile, the filter screen is located outside the window frame, which makes cleaning quite inconvenient. If a user neglects maintenance, impurities such as dust and fluff will gradually accumulate on the surface of the filter screen. After long-term use, this will not only affect the filtration efficiency, but also significantly block the airflow channel, resulting in a large attenuation of the air intake volume and directly weakening the core efficiency of the ventilation system;

[0003] Therefore, an intelligent door and window with a ventilation function is designed to optimize the above problems. Utility Model Content

[0004] The main purpose of the present utility model is to provide an intelligent door and window with a ventilation function to solve the problems raised in the above background art.

[0005] The purpose of the present utility model can be achieved by adopting the following technical scheme:

[0006] An intelligent door and window with a ventilation function comprises an outer frame body, an air duct is arranged inside the outer frame body, the air duct is in a shape of a Chinese character '冂', intake fans are installed at the tops of both ends of the air duct, exhaust ports are opened at both ends of the inner side of the outer frame body, a controller is arranged at the middle position of one end of the inner side of the outer frame body, and a sensor module is arranged at the top of the outer frame body;

[0007] A shaft rod is rotatably installed along the length direction at the inner top of the air duct, one end of the shaft rod is connected with a motor, a baffle is fixed on the shaft rod along the length direction, an arc-shaped filter screen attached to the inner bottom of the air duct is fixed on the inner side of the baffle, and filter elements are arranged at both ends inside the air duct;

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model constructs a highly efficient self-cleaning and ventilation filtration system by fixing a baffle on the shaft at the motor output end and setting an arc-shaped filter screen inside the baffle that fits against the bottom of the outer frame.

[0031] Example 1

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment proposes an intelligent door and window with ventilation function, including an outer frame 1. An air duct 101 is opened inside the outer frame 1, and the shape of the air duct 101 is U-shaped. An air intake fan 102 is installed at the top of both ends of the air duct 101. The type is an axial flow fan (model DC12V8025), with an air volume of 100-150m³ / h, an air pressure of 50-80Pa, a speed of 2000-3000RPM, and a noise level of ≤35dB.

[0033] The outer frame 1 has exhaust ports 104 at both ends on the inner side, a controller 103 at the middle position of one end of the inner side of the outer frame 1, and a sensor module 105 at the top of the outer frame 1.

[0034] A shaft 3 is rotatably mounted on the inner top of the air duct 101 along its length. The shaft 3 is made of 304 stainless steel, has a diameter of 10mm, and its length matches the length of the inner top of the air duct. One end of the shaft 3 is connected to a motor 2. The motor 2 is a 57 stepper motor with a rated voltage of DC24V, a rated current of 1.5A, a step angle of 1.8°, and a reduction ratio of 5:1. It receives pulse signals from the controller 103 through a driver.

[0035] A baffle 4 is fixed on the shaft 3 along the length direction. An arc-shaped filter screen 5 that fits against the bottom of the air duct 101 is fixed on the inner side of the baffle 4. Filter elements 6 are provided at both ends inside the air duct 101.

[0036] The controller 103 is electrically connected to the intake fan 102, the sensor module 105, and the motor 2.

[0037] In use, the sensor module 105 on the top of the outer frame 1 monitors the indoor environment (such as air quality, temperature, and humidity) in real time and transmits the data to the controller 103 inside. When the controller 103 determines that ventilation is needed (such as when poor indoor air quality or temperature and humidity imbalance is detected), it triggers the ventilation program. The controller 103 drives the motor 2 to run, and the motor 2 drives the shaft 3 at the top inside the air duct 101 to rotate 90°. The baffle 4 on the shaft 3 rotates with it, causing the arc-shaped filter 5 inside the baffle 4 to rotate out into the airflow path of the air duct 101. At this time, the arc-shaped filter 5 is tightly attached to the bottom inside the air duct 101, forming a preliminary filtration barrier. The controller 103 simultaneously starts the air intake fans 1 at the top of both ends of the air duct 101. 02. The intake fan 102 draws outdoor air into the U-shaped air duct 101. The air first passes through the arc-shaped filter 5, which filters out large particles (such as dust and lint). Then, the airflow continues to flow through the filter elements 6 at both ends of the air duct 101. The filter elements 6 remove fine particles through deep filtration, completing secondary purification. The purified air is finally delivered into the room through the exhaust port 104 on the inner side of the outer frame 1. After ventilation, the controller 103 drives the motor 2 to reverse, and the baffle 4 drives the arc-shaped filter 5 to reset. During the reset process, the bottom of the air duct 101 is tightly attached to the outer side of the arc-shaped filter 5, scraping off the impurities attached to the filter surface, realizing the self-cleaning of the arc-shaped filter 5 and avoiding the inconvenience of manual cleaning.

[0038] Example 2

[0039] The following section provides a further description of the scheme in Example 1, focusing on its specific working method. See the description below for details:

[0040] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the arc-shaped filter 5 has a mesh size of 0.5-2mm, and the surface of the arc-shaped filter 5 is coated with an oleophobic and hydrophobic coating. The arc-shaped filter 5 adopts a mesh design of 0.5-2mm, which can accurately intercept large particles of different sizes. The oleophobic and hydrophobic coating on its surface can reduce the adhesion of oil and water vapor on the filter surface, reduce the probability of impurity adhesion, and extend the cleaning cycle.

[0041] like Figure 2 As shown, in a preferred embodiment, based on the above method, further, the outer frame 1 is provided with aromatherapy boxes 8 at both ends of the air duct 101, and the aromatherapy boxes 8 are drawer-type structures and are slidably connected to the outer frame 1. The drawer-type aromatherapy boxes 8 can hold aromatherapy tablets or essential oils. When the purified air flows through the air duct 101, it will carry the fragrance released by the aromatherapy boxes 8 and send it into the room from the exhaust port 104 to improve the indoor smell. The aromatherapy boxes 8 adopt a sliding connection design, which makes it convenient for users to take them out and replace the aromatherapy materials at any time.

[0042] like Figure 3and Figure 4 As shown, in a preferred embodiment, based on the above method, a stepped groove 401 is further provided at the bottom of the inner side of the baffle 4, and a rubber strip 402 is provided at the bottom of the inner side of the air duct 101 along the length direction. The stepped groove 401 at the bottom of the inner side of the baffle 4 is closely fitted with the rubber strip 402 at the bottom of the air duct 101, forming a sealing structure during the closing process. When the baffle 4 is unfolded and reset, the rubber strip 402 slides against the surface of the arc-shaped filter screen 5, which can improve the cleaning effect on the surface of the arc-shaped filter screen 5.

[0043] like Figure 2 As shown, in a preferred embodiment, based on the above method, the sensor module 105 further includes at least one of an air quality sensor and a temperature and humidity sensor, and the detection end of the sensor module 105 extends to the inside of the outer frame 1. During the detection process, the sensor module 105 can directly acquire the real indoor environmental data, ensuring that the controller 103 makes more accurate judgments.

[0044] like Figure 2 As shown, in a preferred embodiment, based on the above method, the filter element 6 is further designed to be detachable, and the filter element 6 is fixed to the inner wall of the air duct 101 by means of a snap-fit ​​or magnetic attraction, which makes it more convenient to fix and disassemble.

[0045] like Figure 2 As shown, in a preferred embodiment, based on the above method, a cover plate 7 is provided on the inner side of the outer frame 1 at the position corresponding to the filter element 6, and a snap-fit ​​groove is provided on the cover plate 7. When replacing the filter element 6, the cover plate 7 can be opened, and the user can directly take out the filter element 6 for replacement or cleaning without disassembling the door or window, which solves the problem of inconvenient maintenance of traditional filter screens.

[0046] Example 3

[0047] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0048] The sensor module 105 monitors outdoor environmental parameters in real time. The controller 103 automatically determines whether to start ventilation based on preset logic (indoor environmental threshold). When started, the motor 2 drives the baffle 4 to form a filtration channel with the arc-shaped filter 5. Outdoor air is drawn into the U-shaped air duct 101 inside the outer frame 1 by the intake fan 102. It first flows through the arc-shaped filter 5 for primary coarse filtration. The mesh size of the arc-shaped filter 5 is 0.5-2mm, which can effectively intercept large particles such as dust and lint in the air. In addition, the oleophobic and hydrophobic coating on its surface can reduce oil and water vapor on the filter surface. The surface is adhered to, reducing the probability of impurities sticking together. After the coarse filter, the air continues to flow in the air duct 101, and then undergoes secondary fine filtration through the filter element 6 set at both ends inside the air duct 101. After double purification, the fragrance mixed with the aroma box 8 is sent into the room. At the same time, when the arc-shaped filter 5 is unfolded, the rubber strip 402 fits against the outer side of the arc-shaped filter 5, effectively preventing leakage. After ventilation, the arc-shaped filter 5 achieves self-cleaning through reset friction. The detachable design of the filter element 6 and the aroma box 8 reduces long-term maintenance costs. The whole process does not require manual intervention, realizing the intelligent, efficient and low-maintenance ventilation function.

[0049] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
