Description

Technical Field

[0001] The utility model relates to an automatic opening and closing window, in particular to a window which automatically opens and closes according to temperature. Background Art

[0002] In areas with large temperature differences between day and night, houses need to open windows for ventilation during the day and close them for heat preservation at night. When there are multiple windows installed in a building, workers have to open the windows one by one during the day and close them one by one at night, which is time-consuming and laborious. However, if each window is equipped with an intelligent switch device, it is expensive, and the subsequent maintenance and replacement costs are high. In addition, once a power outage occurs, the intelligent switch device will not work properly. Utility Model Content

[0003] Purpose of the utility model: The purpose of the utility model is to provide an automatic switch window which utilizes the expansion of air when heated and the contraction of air when cooled to control the opening and closing, which has low cost and reliable operation.

[0004] Technical solution: The automatic opening and closing window described in the utility model includes a window frame, and the window frame is equipped with automatic window sashes and manual window sashes that can move left and right. The left and right movement of the automatic window sashes is controlled by a push-pull device. The push-pull device includes a shell and a piston assembly. The shell contains and seals air. One end of the piston assembly is connected to the inside of the shell, and the other end is connected to the automatic window sash. The air in the shell expands when heated and contracts when cooled, driving the piston assembly and the automatic window sash to move.

[0005] Since the requirements for low temperature setting value and high temperature setting value are different in different seasons and regions, in order to improve the adaptability of the window, a ventilation valve for changing the low temperature setting value or the high temperature setting value is provided on the side of the shell facing the room.

[0006] In general scenarios, the air in the shell should be kept consistent with the outdoor temperature as much as possible to ensure the sensitivity and working reliability of the push-pull device. Therefore, an insulation layer can be set on the side of the shell facing the indoor room; if used in seasonal business places such as bathrooms, the air in the shell should be kept consistent with the indoor temperature as much as possible. When the indoor temperature is high, the windows are opened for ventilation, and when the indoor temperature is low, the windows are closed, and the insulation layer is set on the outdoor side. The insulation layer can effectively reduce the impact of indoor or outdoor temperature on the air temperature in the shell.

[0007] Usually, for safety reasons, the space reserved for windows in buildings is limited. By reducing the assembly space of the push-pull device and leaving more space for the window sash, the lighting and ventilation area of ​​the window can be increased. The piston assembly includes a piston tube, a piston and a piston rod. The piston tube is arranged inside the shell. One end of the piston tube is fixed to the side wall of the shell, and the other end is connected to the inside of the shell. When the air in the shell expands when heated and contracts when cooled, it will drive the piston and the piston rod to move in the piston tube. The piston tube provides a storage space for the piston and the piston rod, reducing the assembly space occupied by the push-pull device.

[0008] The piston rod is a multi-stage telescopic structure. Arranging the piston rod into multiple stages can further reduce the assembly space occupied by the push-pull device, thereby further increasing the lighting and ventilation area of ​​the window.

[0009] There are multiple push-pull devices, which are arranged in sequence in the longitudinal direction to drive the automatic window sash to move. As the window is used for a longer time, the friction between the window sash and the track will increase. Multiple push-pull devices can ensure that the window sash can move normally after the friction increases, thereby improving the working reliability of the automatic window opening and closing, and also increasing the service life of the push-pull devices.

[0010] The housings of the adjacent push-pull devices are spaced apart. A gap is formed between the spaced apart housings, and the gap is connected to the outside. The outdoor air flows into the gap to accelerate the heat exchange of the air inside and outside the housing, thereby improving the sensitivity of the push-pull device.

[0011] The window frame includes at least three tracks for installing the automatic window sash and the manual window sash. In order to increase the thermal insulation performance of the window, the number of the manual window sash is two, and the two manual window sashes are respectively installed in the tracks located on both sides of the automatic window sash. The manual window sash can also be used to manually open and close the window. When there is one manual window sash, when you want to manually open or close the window, you need to open the ventilation valve and use the automatic window sash as a manual window sash. When there are two manual window sashes, you can directly achieve the same function as an ordinary window by moving the two manual window sashes, which is convenient and quick.

[0012] Beneficial effects: Compared with the prior art, the utility model utilizes the expansion of air when heated and the contraction of air when cooled to control opening and closing, which is reliable in operation and low in cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figures 1 to 2 As shown, the automatic opening and closing window comprises a window frame 1, wherein the window frame 1 is provided with tracks for installing an automatic window sash 2, a manual window sash 3 and a screen window, and there are two manual window sashes 3, which are respectively installed in the tracks on both sides of the automatic window sash 2. Pulleys are installed between the bottom and tracks of the automatic window sash 2 and the manual window sash 3, and the left and right movement of the automatic window sash 2 is controlled by a push-pull device 4. The push-pull device 4 comprises a housing 41 and a piston assembly 42. The housing 41 contains and seals air. The piston assembly 42 comprises a piston tube 421, a piston 422 and a piston rod 423. The piston tube 421 is located in the housing 41, and one end of the piston tube 421 is welded and fixed to the side wall of the housing 41 close to the automatic window sash 2, and the other end has a gap with the other side wall of the housing 41, and is connected to the inside of the housing 41, so that the air in the housing 41 can enter the piston tube 421, and the air expands when heated and contracts when cooled, which can drive the piston 422 and the piston rod 423 to move in the piston tube 421. The other end of the piston rod 423 is connected to the automatic window sash 2, thereby driving the automatic window sash 2 to move. In order to reduce the installation space of the push-pull device 4, the piston rod 423 is a two-stage telescopic structure. At the same time, in order to ensure the overall strength of the piston rod 423, the piston rod 423 is made of a metal alloy, and the last stage is a solid rod. The automatic opening and closing window is provided with three push-pull devices 4, which are arranged in sequence in the longitudinal direction to drive the automatic window sash 2 to move. The housings 41 of adjacent push-pull devices 4 are arranged at intervals. A heat-insulating layer 5 is provided on the side of the housing 41 facing the room, and the material of the heat-insulating layer 5 is polyurethane foam.

[0020] like Figure 2 As shown, when the temperature is below the low temperature setting value, the push-pull device 4 is in a retracted state, and the automatic window sash 2 is in a closed position. Figure 3 As shown, when the temperature is greater than the low temperature setting value and less than the high temperature setting value, the push-pull device 4 extends, and the automatic window sash 2 leaves the closed position to form a ventilation gap. Figure 4 As shown, when the temperature is above the high temperature setting value, the automatic window sash 2 moves to the maximum opening position.

[0021] like Figure 1As shown, a ventilation valve 43 is provided on the side of the housing 41 facing the room, and the ventilation valve 43 is used to change the low temperature setting value or the high temperature setting value. Moreover, when the user wants to switch to the manual switch mode, he only needs to open the ventilation valve 43. At this time, the housing 41 is connected to the outside world, and the automatic window sash 2 can be manually moved to any position and cooperate with the manual window sash 3 to realize the manual opening and closing of the window. Of course, the manual opening and closing of the window can also be realized by moving the two manual window sashes 3 without opening the ventilation valve 43, avoiding the need to reset the low temperature setting value or the high temperature setting value when using the automatic switch mode.

[0022] like Figure 5 As shown, the automatic opening and closing window further includes a lubricating device 6 for providing lubrication to the push-pull device 4, the lubricating device 6 includes an oil storage container 61 for storing lubricating oil, an oil delivery container 62 connected to the oil storage container 61, and an oil delivery pipeline 63 connected to the oil delivery container 62, a flow valve 64 is further provided between the oil storage container 61 and the oil delivery container 62, and the oil delivery pipeline 63 extends to the piston tube 421. The oil storage container 61 is provided with an oil inlet, and the lubricating oil enters the oil storage container 61 from the oil inlet and is stored in the oil storage container 61, the flow valve 64 controls the supply amount of the lubricating oil, the oil delivery container 62 prevents external air from entering the oil delivery pipeline to damage the seal of the housing 41, the oil delivery pipeline 63 delivers the lubricating oil to the piston tube 421, the piston rod 423 is provided with a small hole above the piston, a part of the lubricating oil enters the piston tube 421, and a part enters the piston rod 423, thereby realizing lubrication of the push-pull device 4.

[0023] The following example takes the low temperature setting value of 10℃ and the high temperature setting value of 20℃ as an example to explain the working process of automatic window opening and closing:

[0024] 1. When the outdoor temperature is 10°C, open the ventilation valve 43, move the automatic window sash 2 to the closed position, and fully retract the push-pull device 4. When the air temperature in the housing 41 reaches 10°C, close the ventilation valve 43 to complete the setting of the low temperature setting value;

[0025] 2. When the temperature is below 10°C, the push-pull device 4 remains in the retracted state, and the automatic window sash 2 is in the closed position;

[0026] 3. When the temperature rises during the day and exceeds 10°C, the air inside the housing 41 expands due to the heat and pushes the piston 422 to move outward. Since the piston 422 is fixed to the piston rod 423 and the piston rod 423 is connected to the automatic window sash 2, the automatic window sash 2 will be pushed to form a gap to ventilate the room.

[0027] 4. When the temperature rises above 20°C, the automatic window sash 2 moves to the maximum opening position, and the automatic window sash 2 reaches the side of the window frame 1, at which time the ventilation area is the largest;

[0028] 5. At night, the temperature drops to below 20°C, and the air inside the housing 41 contracts, forming a negative pressure. The piston 422 moves back, driving the piston rod 423 and the automatic window sash 2 to move, and the ventilation gap gradually decreases.

[0029] 6. When the temperature drops below 10°C, the automatic window sash 2 closes again.

[0030] The above process 1 is to set the low temperature setting value, which does not need to be repeated during the normal operation of the window. There is no order of precedence for processes 2 to 6. The window executes the corresponding working process according to the outdoor temperature during operation.

[0031] If you want to change the low temperature setting value, for example, to change the low temperature setting value to 15°C, you can open the ventilation valve 43 when the outdoor temperature is 15°C, move the automatic window sash 2 to the closed position, let the push-pull device 4 fully retract, and when the air temperature in the shell 41 reaches 15°C, close the ventilation valve 43 to complete the change of the low temperature setting value. Of course, you can also change the high temperature setting value according to actual needs. Specifically, when the outdoor temperature is 25°C, open the ventilation valve 43, move the automatic window sash 2 to the maximum open position, and when the air temperature in the shell 41 reaches 25°C, close the ventilation valve 43, and the high temperature setting value is set.
