Description

Technical Field

[0001] The utility model relates to the technical field of plastic-steel windows, in particular to a plastic-steel window with good ventilation performance. Background Technique

[0002] Plastic-steel windows are a form of window following wooden, iron, and aluminum alloy windows. Due to their relatively low price and good performance-price ratio, they are still widely used. Plastic-steel windows are mainly made of polyvinyl chloride resin, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc. They are extruded into profiles, and then made into door and window frames and sashes by cutting, welding, or screwing. Sealing rubber strips, wool strips, hardware, etc. are assembled. At the same time, to enhance the rigidity of the profiles, steel linings need to be added to the cavities of profiles exceeding a certain length. The doors and windows made in this way are called plastic-steel doors and windows, which are one of the most commonly used window categories in modern architecture. Currently, when using plastic-steel windows, people actively close or open them according to weather changes, and the functions are relatively simple. Generally, plastic-steel windows are mostly closed in rainy, foggy, and sandy weather. After closing, the ventilation performance is poor, which is not convenient for the circulation of indoor and outdoor air to a certain extent. Therefore, a plastic-steel window with good ventilation performance is needed.

[0003] In the publicly disclosed Chinese patent application, the publication number is: CN207715044U, and the patent name is: A plastic-steel window with good ventilation performance. Although, for this plastic-steel window with good ventilation performance, when there is a severely polluted weather, the two pieces of glass are closed, the box door is opened, and the fan is started. The fan sucks air, and the outdoor air enters the interior of the filter box after being filtered by the filter screen for particulate impurities, and then enters the room after being filtered by the activated carbon adsorption net for odor, achieving the effect of accelerating the circulation of indoor and outdoor air and filtering the air, thus effectively solving the problem that general plastic-steel windows are mostly closed in rainy and foggy weather, and the ventilation performance is poor after closing, which is not convenient for the circulation of indoor and outdoor air to a certain extent. However, the automation degree of this existing technology is relatively low, and it cannot open or close the window in time according to weather changes. Content of the Utility Model

[0028] Embodiment 1

[0029] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a plastic-steel window with good ventilation performance includes a mounting bracket 1, a window assembly rotatably arranged on the mounting bracket 1, a ventilation assembly arranged inside the mounting bracket 1, and a control assembly.

[0030] Among them, the mounting bracket 1 is fixedly installed on the window opening during implementation. The window assembly is rotatably arranged on the mounting bracket 1. After the window assembly rotates, the plastic-steel window with good ventilation performance shown in this application is opened or closed. After the window assembly rotates and opens, ventilation and air permeability can be achieved indoors; after the window assembly rotates and closes, the indoor and outdoor air is separated. The ventilation assembly is used to assist ventilation. When the window assembly separates the indoor and outdoor air, under the operation of the ventilation assembly, outdoor air can flow into the room. The control assembly is used to control the window assembly and the ventilation assembly.

[0031] The mounting bracket 1 is composed of two longitudinal beams and two cross beams to form a rectangular frame structure. Air inlet holes 5 are respectively formed on the inner side walls of the two longitudinal beams of the mounting bracket 1, and air outlet ports 8 are respectively formed on the outer side walls of the two cross beams of the mounting bracket 1. The ventilation assembly includes at least one air pump 9. The air inlet end of the air pump 9 is communicated with the air inlet hole 5, and the air outlet end of the air pump 9 is communicated with the air outlet port 8. Specifically, an air inlet pipe 10 is installed at the air inlet end of the air pump 9, and a second through pipe 12 communicated with it is installed at the end of the air inlet pipe 10 away from the air pump 9. The end of the second through pipe 12 away from the air inlet pipe 10 is communicated with the air inlet hole 5.

[0032] Among them, the air inlet hole 5 is communicated with the outside, the air outlet port 8 is located on the indoor side of the plastic-steel window with good ventilation performance shown in the present application, and the air outlet port 8 is communicated with the indoor. The air pump 9 extracts outdoor air through the air inlet hole 5 and conveys the air to the indoor through the air outlet port 8. The air pump 9 can be any one of an air pump and a small blower.

[0033] The window assembly includes a window frame 2, a first glass 3, a second glass 7 and a filter screen 15. The first glass 3 and the second glass 7 are fixedly installed side by side on the inner side wall of the window frame 2. The filter screen 15 is arranged between the first glass 3 and the second glass 7, and a filter cavity is formed between the first glass 3 and the second glass 7. A plurality of first through holes 4 are formed on the first glass 3, and the filter cavity is communicated with the air inlet hole 5.

[0034] Among them, the first glass 3 and the second glass 7 play a role in preventing wind and rain. The filter screen 15 is used to filter the air entering the filter cavity and remove particulate impurities in the air. Outdoor air flows into the filter cavity through each of the first through holes 4 on the first glass 3. The filter screen 15 filters the air, and the air pump 9 extracts the air in the filter cavity through the air inlet hole 5 and conveys the air to the indoor through the air outlet port 8.

[0035] The control assembly includes a control board and a temperature and humidity sensor. The control board is respectively connected to the window assembly and the ventilation assembly for control, and the control board is respectively electrically connected to the temperature and humidity sensor and the air pump 9 through wires.

[0036] Among them, the control board can be one of a single-chip microcomputer and a programmable logic controller. A logic control program and a timing control program are installed inside the control board to meet the need for automatic control of the window assembly and the ventilation assembly. The temperature and humidity sensor is used to detect the temperature and humidity of outdoor air and convert the temperature and humidity into electrical signals and transmit them to the control board. The control board judges whether to close (or open) the window assembly and the ventilation assembly according to the temperature change within a certain period of time. For example, if the outdoor temperature drops by 10 °C within one hour, the control board controls to close the window assembly and controls to open the ventilation assembly; the control board judges whether to close (or open) the window assembly and the ventilation assembly according to the humidity change within a certain period of time.

[0037] Specifically, the two outer side walls of the window frame 2 are respectively fixedly connected with a rotating shaft 11 and a connecting shaft 13 , and the window frame 2 is rotatably connected to the mounting frame 1 via the rotating shaft 11 and the connecting shaft 13 .

[0038] The rotating shaft 11 and the connecting shaft 13 are respectively fixedly mounted on the two outer side walls of the upper part of the window frame 2, and the rotating shaft 11 and the connecting shaft 13 are symmetrically arranged. When the window frame 2 is opened or closed, it rotates clockwise or counterclockwise by a certain angle with the rotating shaft 11 and the connecting shaft 13 as the central axis.

[0039] Specifically, the window assembly further includes a servo motor 14, which is installed inside the mounting frame 1, and the output shaft end of the servo motor 14 is coaxially connected to the connecting shaft 13; the control panel is electrically connected to the servo motor 14 through a wire.

[0040] The servo motor 14 is used to drive the window frame 2 to rotate. After the servo motor 14 is started, the output shaft of the servo motor 14 drives the connecting shaft 13 to rotate, and the connecting shaft 13 drives the window frame 2 to rotate.

[0041] Specifically, a plurality of drainage holes 20 are provided on the lower cross beam of the window frame 2, and each drainage hole 20 is connected to the filter cavity.

[0042] The drainage holes 20 are used to drain the water in the filter cavity. After rainwater enters the filter cavity, it is discharged through each drainage hole 20.

[0043] Specifically, a filter plate 6 is provided on the mounting frame 1 and located at the exhaust port 8 .

[0044] The filter plate 6 is used for secondary filtering of the air transported into the room at the exhaust port 8 .

[0045] During use, when the weather is clear and there is no haze, the control panel starts the servo motor 14, the servo motor 14 drives the connecting shaft 13 to rotate, the connecting shaft 13 drives the window frame 2 to rotate, and the window frame 2 drives the first glass 3, the second glass 7, and the filter 15 to rotate as a whole. When the window frame 2 rotates ninety degrees, the servo motor 14 stops, so that the window is fully opened, the ventilation area is increased, and the ventilation effect is improved.

[0046] In bad weather conditions such as rainy days, the outdoor temperature changes quickly and the air humidity increases. The temperature and humidity sensor transmits the detected outdoor temperature and outdoor humidity data to the control board, which determines whether to close (or open) the window assembly and ventilation assembly based on the temperature changes within a certain period of time. The control board determines whether to close (or open) the window assembly and ventilation assembly based on the humidity changes within a certain period of time.

[0047] When encountering bad weather such as rainy days, (1) the control board activates the servo motor 14, the servo motor 14 drives the connecting shaft 13 to rotate, the connecting shaft 13 drives the window frame 2 to rotate, the window frame 2 drives the first glass 3, the second glass 7, and the filter screen 15 to rotate as a whole. When the window frame 2 rotates to an appropriate angle (in the state where the window is slightly open or closed at an angle less than 90 degrees), the servo motor 14 stops. At this time, under the action of the first glass 3, the second glass 7, and the filter screen 15, rainwater is blocked, preventing rainwater from entering the house through the window. At the same time, the rainwater falling on the first glass 3 will flow through the first through-hole 4 to the filter screen 15, and then the filter screen 15 can be cleaned. Since the first glass 3, the second glass 7, and the filter screen 15 are in an inclined or vertical state at this time, the rainwater entering the filter chamber flushes the filter screen 15. Therefore, the rainwater after cleaning the filter screen 15 will flow to the drain hole 20 and then be discharged through the drain hole 20.

[0048] (2) The control board controls the air pump 9 to start. At this time, the window is in a closed state, and the air inlet hole 5 is connected to the filter chamber. Outdoor air flows through the first through-hole 4, the filter screen 15, the air inlet hole 5, and the exhaust port 8 under the action of the air pump 9 and is then discharged into the room, finally realizing indoor ventilation.

[0049] Embodiment 2

[0050] Please refer to Figures 6 to 7 , the main difference between this embodiment and Embodiment 1 is that: on both cross beams of the window frame 2 and on the side wall close to the filter screen 15, sliding grooves 18 are provided. The filter screen 15 is slidably arranged on the window frame 2 through the sliding grooves 18. A spring 17 is arranged in the sliding grooves 18. One end of the spring 17 is fixedly connected to the cross beam of the window frame 2 through a relief groove 19, and the other end of the spring 17 is fixedly connected to the filter screen 15.

[0051] Among them, the filter screen 15 is slidably arranged on the window frame 2 through the sliding grooves 18. After the servo motor 14 drives the window frame 2 to rotate outward by a certain angle, the whole window frame 2 is inclined. The filter screen 15 slides at the sliding grooves 18 under the influence of its own gravity. When the filter screen 15 slides, it vibrates under the influence of the spring 17, and the dust on the filter screen 15 falls off through the vibration.

[0052] Specifically, cylindrical plugs 16 are installed on some of the first through-holes 4 on the first glass 3. One end of the cylindrical plug 16 protrudes from the side surface of the first glass 3 close to the filter screen 15.

[0053] Among them, the length of the cylindrical plug 16 is slightly greater than the thickness of the first glass 3, and the end of the cylindrical plug 16 close to the filter screen 15 protrudes from the first glass 3. The cylindrical plug 16 can be made of rubber material. The cylindrical plug 16 is used to prevent the filter screen 15 from directly hitting the first glass 3 in the reverse direction and avoid damage to the first glass 3.

[0054] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
