Description

Window with living environment improves function

The application is a divisional application, and the parent application is an application with the invention name of 'window with living environment improvement function' and the application number of 201680038494.X, which is submitted in 2017, 12 and 28 (priority date: 2015, 8 and 11).

Technical Field

The present invention relates to a window having a residential environment improvement function, and more particularly, to a window capable of implementing various functions such as automatic opening and closing of a window sash, natural ventilation, light adjustment for switching a window glass between transparent and opaque states, and opening and closing notification including sensing forced opening and closing of a window sash, using a terminal such as a smart phone in real time regardless of location.

Background

Generally, a window is used as a wall for isolating an indoor from an outdoor, and additionally, as a wall for allowing sunlight and fresh air to enter for indoor ventilation.

In recent years, in addition to simple window opening and closing functions, window systems including automatic sash opening and closing, ventilation, and a safety system incorporated therein have been proposed for the convenience of users.

For example, an automatic opening and closing apparatus capable of slidably opening and closing a window sash by a screw shaft rotated by a driving means to automatically open and close the window sash is disclosed in korean registered patent No. 10-0915952.

However, most automatic window opening and closing devices and ventilation devices are configured such that a user directly manipulates the device indoors using a remote controller in a state where the user is located near the device. When the user goes out, the user may not be able to check whether the ventilation device is operating or whether the window sash is opened or closed. In addition, when it rains, if the user goes out, the user may not close the window sash.

Meanwhile, a security system for preventing thieves and preventing forced entry is configured such that a plurality of sensors are installed at a place where forced entry is expected, and an alarm is generated or forced entry is notified to a security company or a police kiosk when a signal sensed by the sensor indicates such forced entry. One example of providing a window security system is disclosed in korean registered utility model No. 20-0310214.

However, in the conventional security system, a signal indicating forced entry is transmitted only to a contact (contact) set when the security system is initially installed. Therefore, it is not possible for the user to transmit signals to other new contacts.

Also, when the user goes out, the user cannot control the security system, resulting in failure to check whether the security system is operating normally.

Detailed Description

The present invention will now be described in more detail with reference to the following examples. These examples are provided only for illustrating the present invention and should not be construed as limiting the scope and spirit of the present invention.

In the drawings, the same or similar elements are denoted by the same reference numerals even though they are shown in different drawings.

Fig. 1 is a perspective view showing a window having a residential environment improving function according to the present invention, fig. 2 is a view showing an overall structure of the window according to the present invention, and fig. 3 is a front view showing an indoor side of the window according to the present invention.

Referring to fig. 1 and 2, a window 1 having a residential environment improvement function according to one embodiment of the present invention includes at least a pair of window sashes 20 installed in a window frame 10 such that the window sashes 20 can be opened and closed in a sliding manner, and the window 1 includes an automatic opening and closing unit 100, a natural ventilation unit 200, a light adjusting unit 300, an opening and closing notification unit 400, and a control unit 500.

Hereinafter, each unit of the window according to the present invention will be described in detail.

Referring to fig. 3, the automatic opening and closing unit 100 is mounted on a window sash (e.g., a sliding window sash 21) of one of the window sashes 20 configured to be opened and closed in a sliding manner, so as to be capable of automatically opening and closing the sliding window sash 21. The automatic opening and closing unit 100 may be installed in a mullion 21a of a sliding window sash 21 and at an upper or lower portion of the mullion 21a, where the window sashes 20 meet at the mullion 21 a. Alternatively, the automatic opening and closing unit 100 may be installed in the mullion 21a of the sliding window sash 21, and on each of the upper and lower portions of the mullion 21 a. In this embodiment, an example in which the automatic opening and closing unit 100 is installed in the mullion 21a of the sliding sash 21 and on each of the upper and lower portions of the mullion 21a will be shown and described.

Referring to fig. 4, the automatic opening and closing unit 100 may include a driving motor 110 installed in a mullion 21a of a sliding window sash 21, and a driving roller 120, wherein the driving roller 120 is configured to be rotated by power from the driving motor 110 in a state where an outer circumferential surface of the driving roller 120 is in contact with one surface 23a of a fixed window sash 23 installed adjacent to the driving roller 120 to slidably open and close the sliding window sash 21.

In addition, the automatic opening and closing unit 100 may further include an electronic clutch 130 to switch between manual opening and closing of the sliding sash 21 and automatic opening and closing of the sliding sash 21. An electronic clutch 130 is installed on the shaft 111 connecting the driving motor 110 and the driving roller 120 to each other to selectively interrupt power transmission from the motor 110 to the driving roller 120. Therefore, when the current is cut off or when the automatic opening and closing unit 100 malfunctions, the sliding window sash 21 may be manually opened and closed.

The operation of the electronic clutch 130 will be described in detail, the first gear 113 is integrally coupled to a rotation shaft of the driving motor 110, and the first gear 113 is engaged with the second gear 115 to rotate the shaft 111, thereby rotating the driving roller 120. The second gear 115 is coupled to the shaft 111 such that the second gear 115 can idle. The electronic clutch 130 and the second gear 115 are arranged side by side on the same shaft as the shaft 111 so that the electronic clutch 130 can be coupled to the second gear 115. The electronic clutch 130 is integrally fixed to the shaft 111 such that the electronic clutch 130 can rotate together with the shaft 111. An electromagnet (not shown) is provided in the electronic clutch 130.

Therefore, when current is supplied to the electromagnet in the electronic clutch 130, the second gear 115 adjacent to the electronic clutch 130 is coupled to the electronic clutch 130 due to magnetic force, so that the electronic clutch 130 rotates together with the second gear 115. Accordingly, power from the driving motor 110 is transmitted to the driving roller 120 to automatically open and close the sliding sash 21.

On the other hand, when the current supply of the electromagnet in the electronic clutch 130 is interrupted, the electronic clutch 130 is separated from the second gear 115, so that the power from the driving motor 110 is not transmitted to the driving roller 120. Therefore, when the current is cut off or when the automatic opening and closing unit 100 malfunctions, the sliding sash 21 can be manually opened and closed without difficulty.

In this case, the first gear 113 and the second gear 115 may be spur gears. However, in order to reduce noise generated between the first gear 113 and the second gear 115, helical gears may be used as the first gear 113 and the second gear 115.

Referring to fig. 5, the outer circumferential surface of drive roller 120 may be made of rubber or urethane to improve contact between fixed sash 23 and the outer circumferential surface of drive roller 120.

A plurality of grooves 121 may be formed at regular intervals in the outer circumferential surface of the driving roller 120 to increase friction between the outer circumferential surface of the driving roller 120 and the surface 23a of the fixed sash 23 when the outer circumferential surface of the driving roller 120 is in contact with the surface 23a of the fixed sash 23.

In addition, a surface 23a of the fixed sash 23, which is in contact with the outer circumferential surface of the drive roller 120, may be provided with a pad having a protrusion configured to engage with the groove 121, so as to prevent the drive roller 120 from slipping when the drive roller 120 starts rotating. The protrusion pad 123 may be formed on the entire area of the surface 23a of the fixed sash 23 in the direction in which the sliding sash 21 is opened and closed. Alternatively, the protrusion pad 123 may be formed only in a predetermined area where the driving roller 120 in a stationary state starts to rotate.

Referring again to fig. 3, the automatic opening and closing unit 100 may further include a safety sensor 140 for sensing whether a person or an object passes through the window frame 10 while the sliding sash 21 is closed, to immediately interrupt the operation of the driving motor 110. The safety sensor 140 may be installed in a surface 23a of the fixed window sash 23, such as a mullion 23a, or may be installed in the distal end of the sliding window sash 21 in a direction in which the sliding window sash 21 is closed. In this embodiment, the safety sensor 140 is installed in the mullion 23a where the window sash 23 is fixed.

Referring to fig. 6 and 7, the automatic opening and closing unit 100 may further include a pushing means 150 for pressing an outer circumferential surface of the driving roller 120 against the surface 23a of the fixed sash 23. When the automatic opening and closing unit 100 is mounted on the sliding sash 21, the outer peripheral surface of the driving roller 120 does not come into press contact with the surface 23a of the fixed sash 23 due to errors in assembly tolerances among the respective parts constituting the automatic opening and closing unit 100 (see fig. 4). Even in the case where the distance between the outer peripheral surface of the driving roller 120 and the surface 23a of the fixed sash 23 is small, for example, 1-2mm, it is impossible to satisfactorily provide the frictional force.

For this reason, it is necessary to be able to easily adjust the distance between the driving roller 120 and the fixed window sash 23 by providing the pushing means 150, thereby providing the frictional force required to automatically open and close the sliding window sash 21.

Specifically, the pushing device 150 may include: a sliding member 151 having one side coupled to the shaft 111 through a bearing 151a and the other side slidably coupled to a fixed member 151b fixed to the sliding sash 21 (see fig. 7); a support member 153 fixed to the sliding sash 21 such that the support member 153 is spaced apart from the sliding member 151 in a direction in which the sliding member 151 slides, the support member 153 having a fastening hole 153 a; and a manipulation member 155 screw-coupled into the fastening hole 153a in a state that the tip of the manipulation member 155 is in contact with one surface 153c of the sliding member 151 to push the sliding member 151.

In this case, the sliding member 151 may be coupled to the fixed member 151b by a plurality of balls 151d so that the sliding member 151 can smoothly slide.

The manipulation member 155 may be provided with a wrench recess on one surface thereof, wherein the manipulation member 155 may be manipulated using a tool such as a hexagonal wrench. However, the present invention is not limited thereto. The manipulation member 155 may be modified to have various structures such that the manipulation member 155 may be manipulated using various other tools such as a wrench and a driver.

In this embodiment, one side of the sliding member 151 is coupled to the shaft 111 through a bearing 151a so as to move a driving module composed of the driving motor 111 and the driving roller 120. However, the present invention is not limited thereto. The structure of the sliding member 151 is not particularly limited as long as the sliding member 151 can move the driving module including the driving motor 111 and the driving roller 120.

In addition, in order to move the driving module at uniform intervals, a plurality of pushing devices 150 may be installed in the mullion 21a of the sliding sash 21 at predetermined intervals in a longitudinal direction thereof (i.e., a vertical direction).

The automatic opening and closing unit 100 having the above-described structure may be applied to a lifting type sliding window sash as well as a general sliding window sash.

Referring again to fig. 3, a natural ventilation unit 200 is installed in at least one of the sashes 20 to allow fresh air to enter. For example, the natural ventilation unit 200 may be installed in the fixed window sash 23 that is not opened and closed.

In this case, the natural ventilation unit 200 may include a carbon dioxide sensor 210 for measuring the concentration of carbon dioxide in indoor air. The natural ventilation unit 200 may automatically operate when the concentration of carbon dioxide measured by the carbon dioxide sensor 210 exceeds a predetermined reference value.

Any one of the window ventilators disclosed in korean registered patent nos. 10-1274838, 10-1259671, 10-1260564, 10-1301811, 10-1293852, 10-1307645, 10-1433437, 10-1293846, 10-1292365, 10-1330447, 10-1252906, 10-1272994, 10-1338547, 10-1273019, 10-293802, 10-1263991, and 10-1254413, which were filed and registered in the name of the applicant of the present application, may be applied to the natural ventilation unit 200. However, the present invention is not limited thereto. Any ventilator generally used in a window may be applied to the natural ventilation unit 200. A detailed description of the operation of the ventilator for a window will be omitted.

The light adjusting unit 300 is mounted on a part or all of glass provided in the window sash 20 in order to adjust light transmittance of the glass, i.e., to switch the state of the glass between a transparent state and an opaque state. The light conditioning unit 300 is commonly referred to as "magic glass".

The magic glass used as the light adjusting unit 300 is a laminated glass manufactured by pressing two sheets of glass in a state in which an ITO film and a polymer containing liquid crystal are placed between the two sheets of glass. When a voltage is applied to the magic glass, the arrangement of molecules of the liquid crystal in the polymer between the films is changed, so that the state of the glass is switched from an opaque state to a transparent state. The transparency of the glass can be easily changed according to the magnitude of the voltage.

Specifically, in a state where no voltage is applied to the magic glass, liquid crystals (each of which is a stripe-shaped molecule) are aligned along the inner walls of the capsule. In this state, light incident on the magic glass is refracted at the surface of or within the capsule due to the refractive index difference between the polymer and the liquid crystal and the birefringence of the liquid crystal. Therefore, the light is not directly propagated forward, but scattered, and the magic glass becomes opaque.

On the other hand, when a voltage is applied to the magic glass, the liquid crystal is aligned perpendicular to the electrodes due to the properties of the liquid crystal, wherein the alignment direction of the liquid crystal is parallel to the direction of the applied voltage. If in this state the refractive index of the liquid crystal is the same as that of the polymer, this means that the capsules have no interface and the light is not scattered but travels directly forward. Thus, the magic glass becomes transparent.

The opening and closing notification unit 400 includes a sensor 410 mounted on the window 1 for sensing whether the sliding sash 21 has been opened or closed in real time.

In this case, the sensor 410 may include at least one pair of magnet type sensors mounted on the sliding sash 21 and the window frame 10 in a corresponding manner for sensing whether the sliding sash 21 has been opened or closed.

Specifically, the sensor 410 may be buried in an upper portion of the sliding sash 21 and one surface of the window frame 10 corresponding thereto. However, the present invention is not limited thereto. The installation position of the sensor 410 is not particularly limited as long as the sensor 410 can easily sense whether the sliding sash 21 has been opened or closed.

The control unit 500 controls the

units

100, 200, 300, and 400 individually or integrally whenever and wherever possible using the user's wireless communication terminal 510. In addition, the control unit 500 performs control to display the states of the

units

100, 200, 300, and 400 on the display window of the wireless communication terminal 510 in real time.

Specifically, the control unit 500 performs control in a wireless communication manner in which a wireless signal is transmitted to a gateway and then connected to an application installed in the terminal 510 through the internet.

In this case, the wireless communication may be Radio Frequency (RF) communication. However, the present invention is not limited thereto. ZigBee wireless communication supporting near field communication may also be used. For reference, ZigBee wireless communication is one of the IEEE 802.14.4 standards supporting near field communication. ZigBee wireless communication is a technology for near field communication within 10-20m, and is also a ubiquitous computing technology in wireless network areas such as homes or offices. That is, ZigBee is a concept of a portable phone and a wireless local area network. ZigBee differs from the prior art in that a small amount of information is transmitted and power consumption is minimized.

In this embodiment, RF communication or ZigBee wireless communication is used as wireless communication. However, the present invention is not limited thereto. Any one selected from bluetooth, WiFi, WiBro, and Near Field Communication (NFC) may be used as the wireless communication.

In addition, a smart phone, which is easily held and allows a specific application to be installed therein, may be used as the terminal 510. However, the present invention is not limited thereto. Any one of a tablet computer, a cellular phone, a desktop computer, a notebook computer, a tablet notebook computer, and a Personal Digital Assistant (PDA) may be used as the terminal 510.

The control unit 500 having the above-described structure may monitor the current state of the window 1 having various functions in real time through the display window of the terminal 510.

That is, the user may check whether the window 1 has been opened or closed using a specific application installed in the terminal 510. In addition, the user can check the operations of the natural ventilation unit 200, the light adjustment unit 300, and the opening and closing notification unit 400 in real time.

In a state where the window 1 is opened, the user may manipulate a menu of the automatic opening and closing unit 100 in a main menu of an application installed in the terminal 510 to close the sliding window sash 21. After the sliding sash 21 is closed, the user may perform the safety mode through the opening and closing notification unit 400 of the window 1.

Specifically, when the opening and closing notification unit 400 senses a signal, the control unit 500 determines whether the sensed signal indicates forced entry. The control unit 500 first determines whether the window sash 20 is forcibly opened. When it is determined that the window sash 20 has been forcibly opened, the control unit 500 immediately generates an alarm. The alarm may be generated simultaneously through the terminal 510 of the user and a speaker (not shown) provided in the window 1.

In addition, the control unit 500 may transmit a text message or call at least one selected from specific contacts including acquaintances, security companies, control rooms, and police boxes, which have been set in advance by the user, so as to immediately announce the forced entry state.

Alternatively, the control unit 500 may notify the user of the state of forced entry of the terminal 510 using an alarm and may display the above-described measures on a display window so that the user can select one of the above-described measures.

Fig. 8A to 8J are views illustrating application programs installed in a terminal for controlling various functions of a window according to the present invention. Hereinafter, the menu and the function of the application will be described in detail.

Referring to fig. 8A, when an application program starts to be executed, a main menu is displayed on a display window of the terminal 510. The main menu may include a menu for overall control T configured to control all functions in one screen and a menu for controlling the automatic opening and closing unit 100, the natural ventilation unit 200, the light adjusting unit 300, and the opening and closing notification unit 400 configured to display the current states of the respective units and selectively control the respective units in a specific case.

Fig. 8B is a view showing a screen displayed when a menu for the overall control T is selected from the main menu (see fig. 8A) for simply controlling the various functions 100 to 400 under the previously set conditions. Specifically, a closing and opening button for closing and opening the sliding sash 21 may be provided for the automatic opening and closing unit 100, and a stopping and starting button for stopping and starting the ventilation fan may be provided for the natural ventilation unit 200. In addition, a transparent and opaque button for switching between a transparent state and an opaque state of the sash glass to which the magic glass is applied may be provided for the light adjusting unit 300, and a release and set button for releasing and setting the safety function of the house may be provided for the opening and closing notification unit 400.

Fig. 8C is a view showing a screen displayed when a menu for the automatic opening and closing unit 100 is selected from the main menu (see fig. 8A). On this screen, it is possible to display whether or not the sliding sash 21 has been opened or closed, and to open and close the sliding sash 21. Further, a window sash that a user wishes to open or close may be selected from among the window sashes.

In addition, in the menu of the automatic opening and closing unit 100, a degree of opening or closing the window sash 21 may be selected. That is, assuming that the maximum opening width of the window sash 21 is 100cm, the degree of opening and closing of the window sash 21 may be selected such that the window sash 21 is opened by 20-30cm to achieve natural ventilation, or to allow a pet to move between a living room and a balcony when the pet is alone in a house.

Fig. 8D is a view illustrating a screen displayed when a menu of the natural ventilation unit 200 is selected from the main menu (see fig. 8A). On this screen, it is possible to display in real time whether the ventilator is running, when to change the filter, and the carbon dioxide concentration sensed by the carbon dioxide sensor 210.

In addition, when the sensed carbon dioxide concentration is equal to or greater than a reference value (e.g., 800ppm), a screen may be set such that the ventilator automatically operates.

Fig. 8E is a diagram showing a screen displayed when the menu of the light adjusting unit 300 is selected from the main menu (see fig. 8A). On the screen, whether the state of the window sash 20 to which the magic glass is applied is transparent or opaque may be displayed, and furthermore, it is possible to switch between the transparent state and the opaque state in real time.

Fig. 8F is a view showing a screen displayed when the menu of the opening and closing notification unit 400 is selected from the main menu (see fig. 8A). On this screen, the current safety state of the window 1 may be displayed, and the safety function of the window 1 may also be released or set.

Meanwhile, when sensing that the window sash 20 is forcibly opened or closed in a state in which the menu for opening and closing the notification unit 400 is set with the security function, the control unit 500 controls an alarm window shown in fig. 8G to be displayed on the terminal 510 so that the user can send a text message or make a call to at least one of specific contacts including acquaintances, security companies, control rooms, and police kiosks, which the user has set in advance, in order to immediately notify the counterpart of the state of forcible entry.

Referring to fig. 8H, a setup (S) menu is always displayed in the upper right corner of the display window of the terminal 510. When the settings (S) menu is selected, a drop down menu appears.

Fig. 8I is a view showing a screen displayed when a lifestyle (L) menu is selected from a pull-down menu. In the life style (L) menu,
