Description

A multifunctional automatic window closing system

technical field

The invention belongs to the field of household appliances, and relates to an automatic window closing system, in particular to a multifunctional automatic window closing system.

Background technique

With the rapid development of science and technology, the production technology and living standards of China and developed countries are shrinking day by day. , bringing various conveniences to people's daily life.

In large and medium-sized cities, especially in office buildings or residential areas, noise pollution has gradually become one of the environmental pollution that plagues people, and even threatens people's health. Patent 2010202502353 discloses a rainy automatic window closing device, which automatically closes windows only in rainy weather; patent 200920089508.8 discloses a windproof automatic window closing device, which can only automatically close windows in windy conditions. The window closing device can only complete the automatic window closing action under specific circumstances; in addition, along with the noise pollution in the city is gradually serious, so far there is no device that can monitor the noise decibel and perform the automatic window closing action. The invention provides a multifunctional automatic window closing system. When it rains and winds outside the window or the temperature drops suddenly, the window can be automatically closed; when the noise exceeds a certain decibel and lasts for a certain period of time, the window can also be automatically closed. It not only saves people the trouble of getting up and closing windows, but also isolates the harm of noise to people.

Contents of the invention

In view of the above problems, the object of the present invention is to provide a multifunctional automatic window closing system, which will automatically close the windows when the weather changes such as wind, rain, and cooling, or when the external noise reaches a certain decibel and lasts for a certain period of time.

A multifunctional automatic window closing system according to the present invention includes a sensor system box, a controller integrated system box and a rack and pinion window closing system, and is characterized in that the sensor system box, that is, the sensor system, includes a noise sensor , temperature sensor, raindrop sensor, wind speed sensor, the sensor system box is connected with the controller integrated system box through a data line.

The controller integrated system box, that is, the controller integrated system, receives the signal sent by the sensor system, makes a logical judgment, and then sends a command signal to the window closing system to close the window, and also controls the sensor system. The working state of the system, which includes the programmable controller integration and the remote control component, the remote control component can control the opening and closing of the window through the remote control board;

The rack and pinion window closing system can be installed on the installed sliding window, and can also be pre-installed on the bottom of the sliding window, which includes a rack and pinion that can be installed flexibly, a driver, a motor, a window position trigger, etc. , to receive the command sent by the controller to close the window. At the same time, the window position sensor also feeds back the window position information to the controller system. When the window is closed, the motor is stopped to close the window.

The working principle of the present invention is as follows:

When the outdoor temperature suddenly drops, the wind blows, or the weather changes such as heavy rain, the sensor system senses and sends a signal, and the controller controls the window to be closed.

When the outdoor noise exceeds a certain decibel and lasts for a certain period of time, the sensor and the controller cooperate to complete the judgment and close the window.

The anti-noise working principle of this invention is that when the sensor detects noise, the timer I is turned on, that is, the time for detecting noise is set to 10 seconds, and it is detected once per second (the effect of timer II), when the noise exceeds the setting value (noise value harmful to humans), the counter is added once. When the timer 1 timing ends, read the accumulative number of times in the counter again, if the result n is greater than or equal to 6, that is, the harmful noise value of monitoring reaches 6 times or more, just start the motor to close the window and open, if the number of times is less than 6, The windows are not closed, so that too frequent window closing actions caused by accidental noise are eliminated. If the detection system is too sensitive, too many window closing actions will cause disturbance to indoor users.

Compared with the prior art, the present invention has the following advantages:

1) The present invention does not simply close the window when the noise is detected, but when the raindrops, wind speed or noise reaches a certain value and lasts for a certain period of time, the motor is started to close the window to eliminate the misjudgment caused by accidental factors and perform frequent closing. window action;

2) Integrated application of noise sensor, wind speed sensor, raindrop sensor and temperature sensor, expanding the application range of the window closing system;

3) The application of manual remote control increases convenience;

4) Easy to install, the rack and pinion window closing system can be installed on the existing sliding windows, avoiding disassembly of the windows.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing.

As shown in Figure 1, the present invention provides a multifunctional automatic window closing system, mainly comprising: a sensor system box, a controller integrated system box (including its remote control system) and a rack and pinion window closing system. The transmission direction of the signal is shown in Figure 1.

The anti-noise working principle of this invention is as shown in Figure 2, the timer I, the setting time is 10 seconds, the timer II is set as 1 second, and the counter is used to record the number of times that the noise is detected. The specific principle is that when the sensor detects noise, the timer I is turned on, that is, the time for detecting noise is set to 10 seconds, and it is detected once every second (the function of timer II), when the noise exceeds the set value (harmful to humans) noise value), the counter is incremented once. When the timer 1 timing ends, read the accumulative number of times in the counter again, if the result n is greater than or equal to 6, that is, the harmful value of the noise detected reaches 6 times or more, just start the motor to close the window, if the number of times is less than 6, then Do not close the windows, so as to eliminate the excessive frequency of window closing actions caused by accidental noise. If the detection system is too sensitive, resulting in too many window closing actions, it will disturb indoor users instead.

The installation view of the rack and pinion window closing system is as shown in Figure 3 and Figure 4, and the outside and the inside of the window 1 (3) install the rack and pinion (5) (6) (11) (12) with screws (9) (10) simultaneously ), can increase the pulling force to the window and make the window evenly stressed and not easily stuck in the window sliding track I (1), the screw can be appropriately increased according to the situation. Two gears and two motors are respectively driven and linked (not shown on the figure), also in order to increase the pulling force when closing the window. Window position limit block (2) limits window opening position, makes the rack on the window not break away from gear (guarantee rack and pinion work normally). When the window is closed, the window position trigger (8) triggers the closing motor to stop the window closing action, prevents damage to the motor or rack and pinion, and closes the sensor system, which can save energy and save electricity.

According to the above description, relevant staff can make various changes and modifications within the scope of not deviating from the technical idea of the present invention. The technical scope of the present invention is not limited to the contents of the description, and any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
