Description

The technical solution relates to automatic devices for opening windows in rooms with adjustable thermal conditions.

The device according to the patent RU 135 486 U1, published on 12/20/2013, comprising an electric motor with a reducer, a closing opening mechanism connected at one end to the output shaft of the reducer, an electronic unit and a power unit, the electronic unit including a digital temperature sensor, is known from the prior art. CPU.

This known device serves as a prototype of the claimed technical solution.

A disadvantage of the known device is the use of limit switches and electromagnetic relays that do not adequately protect against short-circuiting the wires of the electric motor and the electric motor when the gearbox and the closing opening mechanism are jammed. The next disadvantage is the regulation of temperature only.

The objective of the claimed utility model is to develop an automatic device for opening or closing a window or window for a given period of time according to several parameters (temperature, CO2 content), a simple and reliable design.

The technical result of the proposed solution is to expand the parameters for regulation while increasing the reliability of the device.

The problem is solved in that in an automatic device for opening windows containing an electric motor with a reducer, a closing opening mechanism connected at one end to the output shaft of the reducer, an electronic unit and a power supply, while the electronic unit includes a digital temperature sensor, the processor is inserted into an electronic unit associated with the processor carbon dioxide sensor, Wi-Fi module, transistor keys, power components, controls and displays, stand-alone control panel, while the device is made with the ability to change the operating mode of the information about the measured temperature or the content of carbon dioxide from the respective sensors, on information from the schedule exact opening and closing time. The components for power are made in the form of a 3.7-4.2 V battery, a 3.7 V to 12 V voltage converter, and a charging circuit. The controls and indications are made in the form of a display and a keyboard containing at least 3 buttons. The standalone control panel is configured to communicate according to the 433 MHz wireless standard.

Figure 1 shows a general view of the design of an automatic device (phase closed).

Figure 2 shows a general view of the design of the automatic device (phase "open").

Figure 3 shows the block diagram of the device.

In Fig. 6, 7, 8, 9, 10, 11, methods of installing the device on the window frame and window panes are shown.

An automatic window opening device includes:

1 - transmitter, 2 - buttons from the remote control, 3 - processor, 4 display, 5 - keyboard, 6 - receiver, 7 - carbon dioxide sensor, 8 - temperature sensor, 9 - Wi-Fi element, 10 - transistor keys, 11 - current sensor, 12 - power converter, 13 - motor, 14 - gearbox, 15 - closing opening mechanism, 16 - battery, 17 - charging circuit, 18 - mains adapter

An automatic device for opening contains a closing opening mechanism 15, an electronic unit and a power supply unit, an electric motor with a gearbox, an output shaft connected to one end of the closing opening mechanism in the housing. A stand-alone remote control for controlling the device remotely in manual mode and consists of a transmitter unit 1 at 433 MHz and control buttons 2. The electronic unit contains a receiver 6 at 433 MHz for receiving commands from the remote control, processor 3, configured to receive signals from sensors and compare received data with control and issuing control signals. The processor receives commands of the following elements of the electronic unit: from the keyboard 5, carbon dioxide sensor 7, Wi-Fi module 9, temperature sensor 8, provides information on the liquid crystal display 4, provides signals to transistor switches 10, reads data from the current sensor 11. Current sensor 11 replaces the limit switches, provides protection against short circuit of the wires of the electric motor 13, protects the electric motor when the gearbox 14 and the closing opening mechanism 15 are jammed.

The transistor switches 10 are powered by a 12 V voltage converter 12 from 3.7 V to 12 V. A voltage converter of 3.7 V to 12 V provides a large electric motor power. When using a 12 V electric motor of 2000 rpm with a gearbox of 1 \ 600, the moment of force is reached up to 60 kg \ cm, which facilitates the use of the device for large windows or windows that are tightly closed if you apply a lot of force to them. The device is powered by a 16 to 3.7-4.2 V battery. The battery is made in the form of a lithium-ion battery; it is charged by charging circuit 17. The device can operate independently or in conjunction with a network adapter 18 by 110 ... 220 \ 5 V. Wi-Fi module 9 provides the exchange of information according to the wireless standard for setting up and controlling the processor from a personal computer or smartphone remotely. Display 4 is made to display the current time, temperature and device settings. Keyboard 5 contains at least 3 buttons for entering information and device settings.

The inventive device by means of an electronic module and an associated closing opening mechanism controls, i.e. opens or closes the window according to the received information about the parameters at a particular moment in time, analyzes them and issues a command for transistor switches 10 for the device to work in a certain mode.

The electronic module is configured to operate in several modes:

Scheduled mode - there are 20 programs with the exact time of opening and closing the window in minutes and hours.

Range operation mode - the user sets the time of the open window in minutes and the pause time between openings in minutes (for example, 3 minutes the window is open every 17 minutes, i.e. within an hour the window will open 3 times for 3 minutes and so on cyclically, if you put 1 minute after 4 minutes, then within an hour the window will open 6 times for 1 minute).

The operating mode for the full opening range is the time interval in hours and minutes during which the window is open regardless of the “scheduled” settings (for example, during the day from 12:00 to 16:00 the window will be fully open regardless of other settings).

The operating mode for the range of full closure is similar to the “full open” algorithm only during this period of time the window is completely closed. (for example, from 23:00 to 6:00 the window will always be closed, it is used for living rooms or greenhouses so that the windows are always closed in the evening or at night).

Operating mode according to the temperature sensor - the window opens and closes depending on the set temperature threshold (used for greenhouses).

Carbon dioxide sensor operating mode - sets a threshold value from 0 to 2,000 conventional units, at which the window opens for a limited time interval and pauses between them, is set in minutes, for example, we set the time interval 2 minutes open 18 minutes closed, with a threshold value for the CO2 sensor - 1200 units, if the sensor values become higher than 1200 units then the window works as “scheduled” if the threshold value is not exceeded, then the window is always closed (used for houses, apartments and office buildings).

Operating mode from the remote control - regardless of what the status in the program is in the manual mode, the user can open or close the window remotely, at any time.

An automatic device for opening windows is made with the possibility of installing on the frame of a window or window leaf in various ways (FIGS. 6, 7, 8, 9, 10, 11).

The inventive automatic device for opening windows has eliminated the disadvantages of the known device, to provide an extension of the parameters for regulation while increasing the reliability of the device by introducing a carbon dioxide sensor, current sensor, stand-alone remote control.

The inventive device is planned to be used to control windows, which allows us to conclude that it meets the criterion of "industrial applicability" for the utility model.
