Description

Technology Field

[0001] The present invention relates to a window opening and closing system that considers indoor and outdoor environmental data, and to a technology that automates the opening and closing of windows by utilizing IoT and automatic control technologies, and improves user convenience and safety. Background Technology

[0002] In modern buildings, maximizing energy efficiency and maintaining a comfortable indoor environment are considered important factors. In particular, window opening and closing methods are important means of improving indoor air quality and reducing heating and cooling energy consumption; however, existing window opening and closing methods have limitations in that they rely on manual operation by users, making it difficult to meet demands for energy saving, indoor environment optimization, and enhanced security.

[0003] Existing window opening and closing systems provide only simple opening and closing functions and do not reflect changes in the indoor and outdoor environment, leading to issues such as unnecessary energy loss or inadequate indoor air quality management. For example, if windows are opened during heating in winter, there is a high likelihood of heating energy loss, and if windows are opened during cooling in summer, hot outdoor air may flow into the room, potentially increasing the cooling load. Furthermore, opening and closing windows without considering differences in indoor and outdoor fine dust concentrations, carbon dioxide concentrations, or wind speed can worsen indoor air quality, and there are problems such as increased security threats if windows remain open even when the user is away.

[0004] To solve these problems, the present invention provides a system that automatically optimizes window opening and closing by comprehensively analyzing indoor and outdoor environmental data and security factors. The system analyzes data such as indoor and outdoor temperature, humidity, fine dust concentration, and carbon dioxide concentration in real time to calculate an environmental suitability score, and enables the automatic determination of whether to open or close the window based on this score. The problem to be solved

[0005] The problem that the present invention aims to solve is to provide a window opening and closing device installed on the side of a window.

[0006] The problem that the present invention aims to solve is to provide a window opening and closing device that detects the position of a window and controls the opening and closing operation.

[0007] The problem that the present invention aims to solve is to provide a window opening and closing device that improves user convenience by automatically analyzing indoor and outdoor environmental data, the degree of energy saving, and the security situation of the residence to determine whether to automatically open or close the window. means of solving the problem

[0008] The window opening and closing system of the present invention comprises: a window opening and closing device installed on a first window and a second window that are movable to move in a lateral direction and overlap each other, and a server that determines whether to open or close the window based on at least one of an environmental suitability score, an energy saving score, or a security score; wherein the window opening and closing device comprises: a body; a coupling part connected to one side of the body and coupled to the side of the first window; and a moving part, a portion of which is formed protruding from one surface of the body facing the second window and moves one of the first window or the second window using frictional force with the second window.

[0009] The above environmental suitability score is a score that evaluates whether opening and closing windows is appropriate for improving the indoor environment, and can be determined based on the temperature difference, humidity difference, fine dust concentration difference, and carbon dioxide concentration difference obtained by subtracting the indoor measurement value from the outdoor measurement value.

[0010] The server may increase the environmental suitability score as the absolute value of the temperature difference increases, but decrease the environmental suitability score to prevent indoor condensation if the absolute value of the humidity difference exceeds a preset threshold, and increase the environmental suitability score as the carbon dioxide concentration difference increases, but decrease the environmental suitability score in proportion to the fine dust concentration difference if the fine dust concentration difference has a positive value.

[0011] The above server obtains wind speed data from collected weather data and, if the wind speed is greater than or equal to a preset threshold value, decreases the environmental suitability score to prevent an increase in indoor fine dust, but, if the temperature difference has a negative value and the wind speed is less than or equal to the preset threshold value, increases the environmental suitability score to induce a natural cooling effect.

[0012] The above server may reduce the energy saving score as the temperature difference increases, and reduce the energy saving score as the humidity difference increases to prevent an increase in the load of the air conditioning system.

[0013] The above server may reduce the security score as the duration of the user's absence increases, and may reduce the security score as the distance between the user and the window opening / closing device, calculated based on GPS information collected from the user terminal, increases.

[0014] If a load is detected on the moving part while no user operation command is transmitted to the window opening / closing device, it is determined that there is an attempt to forcibly open the first window or the second window, and the security score may be reduced.

[0015] The device may further include a control unit that increases the minimum torque value for the moving part to operate when a load is detected in the moving part while no user operation command is transmitted to the window opening / closing device. Effects of the invention

[0016] According to the window opening and closing system of the present invention, there is an effect of being able to provide a window opening and closing device installed on the side of the window.

[0017] According to the window opening and closing system of the present invention, there is an effect of being able to detect the position of the window and control the opening and closing operation.

[0018] According to the window opening and closing system of the present invention, by automatically analyzing indoor and outdoor environmental data, the degree of energy saving, and the security situation of the residence to determine whether to automatically open or close the window, the convenience of the user can be improved.

Specific details for implementing the invention

[0020] The embodiments are described in detail below with reference to exemplary drawings. It should be noted that when assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the embodiments, if it is determined that a detailed description of related known configurations or functions would hinder understanding of the embodiments, such detailed description is omitted.

[0021] Additionally, terms such as first, second, A, B, (a), (b), etc., may be used when describing the components of the embodiments. These terms are intended only to distinguish the components from other components, and the nature, order, or sequence of the components is not limited by the terms. Where it is stated that a component is "connected," "combined," or "joined" to another component, it should be understood that the component may be directly connected or joined to the other component, but that another component may also be "connected," "combined," or "joined" between each component.

[0022] Components included in any one embodiment and components having common functions shall be described using the same names in other embodiments. Unless otherwise stated, the description in any one embodiment may also apply to other embodiments, and specific descriptions shall be omitted to the extent of overlap.

[0023] FIG. 1 is a perspective view of a window opening / closing device (1) according to an embodiment of the present invention installed on a closed window, and FIG. 2 is a perspective view of a window opening / closing device (1) according to an embodiment of the present invention installed on an open window.

[0024] Referring to FIGS. 1 and 2, a window opening / closing device (1) according to an embodiment of the present invention is installed on a window to control whether the window is opened or closed. For example, the window opening / closing device (1) may be installed on a first window (S1) and a second window (S2) that are movable to move in a lateral direction and overlap each other. Specifically, the first window (S1) and the second window (S2) may include sliding windows.

[0025] In other words, the first window (S1) and the second window (S2) may be movable along surfaces facing each other while partially overlapping. That is, based on the user's view from inside the indoor space, the first window (S1) and the second window (S2) may move in left and right directions, and the indoor space may be sealed off from or opened off from the outside space. However, the structure of the first window (S1) and the second window (S2) on which the window opening / closing device (1) is installed is not limited thereto and may include various sliding structures that open and close the indoor space and the outdoor space.

[0026] The window opening / closing device (1) can be coupled to the side (S10) of the first window (S1). For example, the first window (S1) and the second window (S2) may face the interior space in a forward direction, and the first window (S1) may be positioned in front of the second window (S2). The window opening / closing device (1) may be installed to be located in front of the second window (S2) while also being coupled to the side (S10) of the first window (S1).

[0027] Additionally, based on the view from the top, the width of the window opening / closing device (1) may be smaller than the width of the first window (S1).

[0028] According to this structure, in a situation where a plurality of first windows (S1) and a plurality of second windows (S2) are designed to alternate with each other, the window opening and closing device (1) can be placed in the space between the plurality of windows, thereby occupying the installation space more efficiently.

[0029] Next, the window opening / closing device (1) may not move the first window (S1) or the second window (S2) when the first window (S1) or the second window (S2) has moved a certain distance. For example, when the first window (S1) or the second window (S2) moves a certain distance, the window opening / closing device (1) may detect a specific point on the second window (S2) and stop the movement of the first window (S1) or the second window (S2).

[0030] Specifically, a first point (P1) and a second point (P2) are marked on the second window (S2), and when the window opening / closing device (1) detects the first point (P1) of the second window (S2) during the process of opening the second window (S2), it is determined that the second window (S2) is sufficiently opened and the operation of opening the second window (S2) can be stopped. Conversely, when the window opening / closing device (1) detects the second point (P2) of the second window (S2) during the process of closing the second window (S2), it is determined that the second window (S2) is closed and the operation of closing the second window (S2) can be stopped.

[0031] The above example is an example in which the opening and closing operation of the second window (S2) is performed while the first window (S1) is in place, and conversely, the first window (S1) can be opened or closed by the window opening and closing device (1) while the second window (S2) is fixed.

[0032] With the control operation of the window opening and closing device (1) as described above, the convenience of use and user satisfaction can be further enhanced by preventing the window from opening beyond a certain limit, and the problem of the device being damaged or broken can be prevented in advance by preventing further closing operation from occurring while it is in a closed state.

[0033] FIG. 3 is a front view perspective of a window opening / closing device (1) according to an embodiment of the present invention, and FIG. 4 is a rear view perspective of a window opening / closing device (1) according to an embodiment of the present invention. FIG. 5 is an internal configuration diagram showing one side (10a) of the body (10) of the window opening / closing device (1) according to an embodiment of the present invention removed, and FIG. 6 is an enlarged view of the window opening / closing device (1) according to an embodiment of the present invention.

[0034] Referring to FIGS. 3 to 6, the window opening / closing device (1) may include a body (10), a connecting part (11), a moving part (12), and a controlling part (13).

[0035] The body (10) can form the exterior of the window opening / closing device (1). For example, the body (10) can form an empty space inside, and components necessary for operating the window opening / closing device (1) can be placed in the empty space inside.

[0036] The body (10) may be formed to be positioned on the side (S10) of the first window (S1). For example, when viewed from above, the width of the body (10) may be smaller than the width of the first window (S1). Additionally, the body (10) may include a roughly rectangular shape. However, the shape of the body (10) is not limited thereto and may include various shapes that can be positioned between a plurality of second windows (S2).

[0037] The connecting part (11) is connected to one side of the body (10) and can be connected to the side (S10) of the first window (S1). For example, the connecting part (11) can be installed on the side (S10) of the first window (S1) and can connect the body (10) and the first window (S1) to each other. Specifically, the connecting part (11) is installed and connected to the side (S10) of the first window (S1) through screw connection, and the window opening / closing device (1) can be installed on the first window (S1) by connecting the body (10) to the connecting part (11) while the connecting part (11) is connected to the first window (S1).

[0038] Additionally, the connecting portion (11) may be formed along the side (S10) of the first window (S1). That is, the longitudinal direction of the connecting portion (11) may be parallel to the vertical direction.

[0039] The connecting part (11) may include a connecting part (110) and a fixing part (111).

[0040] The connecting part (110) is connected to one side of the body (10) and can be coupled with the side (S10) of the first window (S1) to connect the body (10) to the first window (S1). For example, when one side of the connecting part (110) is in contact with the side (S10) of the first window (S1), the connecting part (110) can be coupled to the first window (S1) through screw coupling with the side (S10) of the first window (S1).

[0041] At this time, the other side of the connecting part (110), which is the opposite side of one side, may include a specific shape that is coupled with the body (10). For example, the body (10) and the connecting part (110) may include an uneven shape formed in a shape corresponding to each other on the surfaces connected to each other.

[0042] In other words, the other surface of the connecting part (110) includes an uneven shape formed to protrude toward the body (10), and likewise, an uneven shape may be formed on the surface of the body (10) facing the connecting part (110). The uneven shapes of the body (10) and the connecting part (110) may be interlocked and connected to each other.

[0043] The fixing part (111) can fix the body (10) and the connecting part (110) by penetrating the body (10) and the connecting part (110). For example, when the uneven shapes of the body (10) and the connecting part (110) are interlocked and connected, the fixing part (111) can be formed to penetrate the uneven shapes of the body (10) and the connecting part (110). That is, the fixing part (111) can be formed to alternately penetrate the uneven shapes of the body (10) and the connecting part (110). Based on the user's view from the interior space, the longitudinal direction of the fixing part (111) can be parallel to the vertical direction.

[0044] The moving part (12) can move either the first window (S1) or the second window (S2) by utilizing frictional force with the second window (S2). For example, a part of the moving part (12) may be formed on the inner side of the body (10), and another part of the moving part (12) may be formed protruding from one side (10a) of the body (10). The one side (10a) of the body (10) may be the side (10a) facing the second window (S2).

[0045] In other words, the body (10) is formed along the direction of movement of the first window (S1) and the second window (S2) from the side (S10) of the first window (S1), and the moving part (12) protrudes from the body (10) toward the rear direction and can come into contact with the second window (S2).

[0046] The moving part (12) includes a surface material with high friction, such as rubber, and can move the first window (S1) or the second window (S2) by pushing the second window (S2) while in contact with the second window (S2). That is, when the first window (S1) is fixed, the second window (S2) can be moved, and when the second window (S2) is fixed, the first window (S1) can be moved.

[0047] Specifically, the moving part (12) may include a motor (120) and a driving part (121).

[0048] The motor (120) is located inside the body (10) and can generate rotational force. For example, the motor (120) can receive power from the power supply unit (16) described later and convert electrical energy into mechanical kinetic energy. Depending on the usage environment and design environment, the motor (120) may be a DC motor (120), a stepper motor (120), or a servo motor (120).

[0049] The drive unit (121) is connected to the rotation axis of the motor (120) and can rotate by the rotational force of the motor (120). Accordingly, the drive unit (121) can move either the first window (S1) or the second window (S2). For example, the drive unit (121) may include a wheel shape that contacts the second window (S2) and can rotate by the rotational movement of the motor (120). A part of the drive unit (121) may protrude from one side (10a) of the body (10) and contact the second window (S2), and can move the first window (S1) or the second window (S2) through frictional force with the second window (S2).

[0050] Specifically, the motor (120) can be fixed to the inner surface of one side (10a) of the body (10). With respect to the rotation axis of the motor (120), the outer surface of the driving part (121) is spaced further away from the rotation axis of the motor (120) than the outer surface of the motor (120), so that the driving part (121) can be formed to protrude from one side (10a) of the body (10).

[0051] More specifically, the rotation axis of the motor (120) can be formed along the side (S10) of the first window (S1) and perpendicular to the direction of movement of the second window (S2). That is, when the window opening / closing device (1) is coupled with the first window (S1), the motor (120) can be positioned so that the longitudinal direction of the motor (120) is parallel to the side (S10) of the first window (S1). In other words, the motor (120) can be positioned in an up-and-down direction.

[0052] At this time, based on one side (10a) of the body (10) facing the second window (S2), the motor (120) and the second window (S2) are located on both sides of one side (10a) of the body (10), and the motor (120) can be connected and fixed to the inner side of one side (10a) of the body (10).

[0053] Based on the reference point from the rotation axis of the motor (120), that is, based on the reference point from the upper side, the driving unit (121) may occupy a larger area than the motor (120). In other words, the motor (120) and the driving unit (121) may be formed such that, based on the reference point from the rotation axis of the motor (120), the area occupied by the driving unit (121) is formed further outward than the area occupied by the motor (120).

[0054] Due to the difference in size between the motor (120) and the drive unit (121) and the fact that the motor (120) is attached to the inner surface of one side (10a) of the body (10), the drive unit (121) can protrude from one side (10a) of the body (10) and come into contact with the second window (S2) and move the first window (S1) or the second window (S2).

[0055] The driving unit (121) is formed on one side (10a) of the body (10) facing the second window (S2), rather than on the lower surface of the body (10), thereby allowing the first window (S1) or the second window (S2) to be moved more effectively and preventing structural defects in the first window (S1) or the second window (S2) caused by the use of the window opening / closing device (1). Specifically, if the driving unit (121) is formed on the lower surface of the body (10), the driving unit (121) comes into contact with the lower part of the second window (S2) or the point where the window and the window frame are connected. Since that part is a part where resin molding is formed or where the structural bonding force is weak, if the driving unit (121) is formed on the lower surface of the body (10), problems such as damage or defects may occur in that part.

[0056] Additionally, the window opening / closing device (1) may be positioned in the space between the widths of the second window (S2). For example, the window opening / closing device (1) may be positioned in the space between the extension line of the front surface of the first window (S1) and the extension line of the rear surface of the first window (S1), based on the reference from the rotation axis of the motor (120), that is, based on the reference from the upper side.

[0057] Specifically, based on the view from the rotation axis of the motor (120), the distance between the end of the driving part (121) protruding from one side (10a) of the body (10) and the other side (10c) of the body (10), which is the opposite side of the one side (10a) of the body (10), may be smaller than the width of the first window (S1).

[0058] According to the size of the window opening / closing device (1) as described above, even if a plurality of first windows (S1) and a plurality of second windows (S2) are arranged alternately, the window opening / closing device (1) can be placed between the plurality of second windows (S2) and combined with the first window (S1), thus occupying the installation space more efficiently.

[0059] The control unit (13) can control the operation of the moving unit (12). For example, the control unit (13) may include a circuit board and control the operation of the moving unit (12) by transmitting an electrical signal to the moving unit (12). Additionally, the control unit (13) may receive a signal from another component and control the operation of the moving unit (12) according to the received signal.

[0060] Specifically, the control unit (13) can receive a signal from the detection sensor (14) described later and control the operation of the moving unit (12) according to the signal of the detection sensor (14). For example, the control unit (13) can stop the opening or closing operation of the moving unit (12) according to the signal of the detection sensor (14). A detailed explanation will be provided later in the description of the detection sensor (14).

[0061] Next, the control unit (13) can control the operation of the moving unit (12) according to the user's operation signal. For example, the window opening / closing device (1) may further include an input unit (15) formed on the outer surface of the body (10) and receiving an operation signal from the user. The input unit (15) includes a switch form formed on the outer surface of the body (10) and can be pressed by the user's operation. The input unit (15) may include a button for the direction in which the first window (S1) or the second window (S2) closes, a button for the direction in which the first window (S1) or the second window (S2) opens, and a button for stopping the first window (S1) or the second window (S2), for a total of three buttons. The control unit (13) receives information input by the user through the input unit (15) and can control the operation of the moving unit (12) according to the input information.

[0062] Additionally, the control unit (13) can control the operation of the moving unit (12) according to a signal from an external device. For example, through wireless communication such as an application of a wireless terminal or a remote controller, the control unit (13) can receive an operation signal from the outside and control the operation of the moving unit (12) according to the received operation signal.

[0063] The control unit (13) may be positioned spaced apart from the coupling unit (11) than the motor (120). Specifically, the control unit (13) and the motor (120) may be arranged along the direction of movement of the first window (S1) and the second window (S2). In other words, the control unit (13) and the motor (120) may be arranged side by side along the surface direction of the second window (S2). That is, they may be arranged and formed in the order of the coupling unit (11), the motor (120), and the control unit (13) along the second window (S2).

[0064] According to the arrangement order of the coupling part (11), motor (120) and control part (13) as described above, the motor (120) and control part (13) occupy a narrower space inside the body (10), so the body (10) can be thinner, and the window opening / closing device (1) can occupy a narrower space on the side (S10) of the first window (S1).

[0065] The window opening / closing device (1) may further include a detection sensor (14) located on the inside of the body (10) and detecting a specific point of the second window (S2). For example, the body (10) includes a through hole (10b) formed through one side (10a), and the detection sensor (14) may detect a specific point of the second window (S2) through the through hole (10b) while located on the inside of the body (10).

[0066] Specifically, the detection sensor (14) may include an opening sensor (140) that detects an open state of either the first window (S1) or the second window (S2) by detecting a first point (P1) of the second window (S2), and a closing sensor (141) that detects a closed state of either the first window (S1) or the second window (S2) by detecting a second point (P2) of the second window (S2).

[0067] More specifically, when the second window (S2) is opened by the moving part (12) based on the indoor space, that is, based on the front view, and the first point (P1) of the second window (S2) passes the lower side of the opening sensor (140), the opening sensor (140) can detect the first point (P1). Conversely, when the second window (S2) is closed by the moving part (12) based on the indoor space, that is, based on the front view, and the second point (P2) of the second window (S2) passes the lower side of the closing sensor (141), the closing sensor (141) can detect the second point (P2).

[0068] The distance between the first point (P1) and the side (S10) of the first window (S1) may be longer than the distance between the second point (P2) and the side (S10) of the first window (S1). That is, the first point (P1) may be formed further from the side (S10) of the first window (S1) than the second point (P2).

[0069] Even when the second window (S2) is fixed and the first window (S1) is moved, the opening sensor (140) can detect the first point (P1) and the closing sensor (141) can detect the second point (P2).

[0070] The open sensor (140) and the close sensor (141) may be separate sensors. That is, the same sensor may not perform the functions of the open sensor (140) and the close sensor (141), but each sensor may perform the functions of the open sensor (140) and the close sensor (141).

[0071] The control unit (13) can stop the operation of the moving unit (12) by receiving a signal from the detection sensor (14) that a specific point of the second window (S2) has been detected. For example, if the control unit (13) receives a signal from the opening sensor (140) that a first point (P1) of the second window (S2) has been detected, the control unit (13) can stop the operation of the moving unit (12) that moves either the first window (S1) or the second window (S2) to open. Conversely, if the control unit (13) receives a signal from the closing sensor (141) that a second point (P2) of the second window (S2) has been detected, the control unit (13) can stop the operation of the moving unit (12) that moves either the first window (S1) or the second window (S2) to close.

[0072] According to the operation of the detection sensor (14) and the control unit (13), the window opening / closing device (1) may not move the first window (S1) or the second window (S2) when the first window (S1) or the second window (S2) has moved a certain distance. For example, when the first window (S1) or the second window (S2) moves a certain distance, the window opening / closing device (1) may detect a specific point on the second window (S2) and stop the movement of the first window (S1) or the second window (S2).

[0073] Accordingly, the window opening / closing device (1) can increase user convenience or user satisfaction by preventing the window from opening beyond a certain limit, and can prevent the problem of the device being damaged or broken by preventing further closing operations while it is in a closed state.

[0074] The window opening / closing device (1) may further include a power supply unit (16) that supplies power to the moving part (12). The power supply unit (16) may include means for storing electrical energy. Specifically, the power supply unit (16) may include a battery.

[0075] The power supply unit (16) can be arranged to be stacked on the control unit (13). For example, when the direction of looking at the first window (S1) or the second window (S2) in the indoor space is the direction viewed from the front, the power supply unit (16) and the control unit (13) can be arranged along the direction viewed from the front.

[0076] According to the arrangement relationship of the power supply unit (16) and the control unit (13) as described above, the power supply unit (16) and the control unit (13) occupy the internal space of the body (10) more compactly, so the internal space of the body (10) can be occupied less, and the body (10) can be made thinner, so the window opening / closing device (1) can occupy the installation space more efficiently.

[0078] FIG. 7 is a diagram illustrating an example of a network environment according to one embodiment. The network environment of FIG. 7 illustrates an example including a window opening / closing device (1), a server (730), and a network (720). FIG. 7 is an example for explaining the invention, and the number of window opening / closing devices (1) or the number of servers are not limited to that shown in FIG. 7. Furthermore, the network environment of FIG. 7 is merely an example of one of the environments applicable to the embodiments, and the environments applicable to the embodiments are not limited to the network environment of FIG. 7.

[0079] The communication method is not limited and may include not only communication methods utilizing communication networks (e.g., mobile communication networks, wired internet, wireless internet, broadcasting networks) that the network (720) may include, but also short-range wireless communication between devices. For example, the network (140) may include any one or more networks such as a PAN (personal area network), LAN (local area network), CAN (campus area network), MAN (metropolitan area network), WAN (wide area network), BBN (broadband network), and the Internet.

[0080] Each server (720) may be implemented as a computer device or a plurality of computer devices that communicate with the window opening / closing device (1) and the network (720) to provide commands, code, files, content, services, etc. For example, the server (730) may be a system that provides services (e.g., cloud service, game service, content provision service, group call service (or voice conference service), messaging service, mail service, social network service, map service, translation service, financial service, payment service, search service, etc.) to the window opening / closing device (1) connected through the network (720).

[0081] FIG. 8 is a flowchart illustrating a method for determining whether to automatically open or close a window based on an environmental suitability score, an energy saving score, and a security score according to an embodiment of the present invention.

[0082] The window opening and closing system of the present invention is a device that provides an automatic opening and closing function for improving the indoor environment, saving energy, and enhancing security, and can be installed on a first window and a second window that can move laterally and overlap each other. The window opening and closing system may include a window opening and closing device that automatically opens and closes the window, and a server that determines whether to open or close the window based on at least one of an environmental suitability score, an energy saving score, or a security score. The window opening and closing device includes a body, a coupling part, and a moving part to effectively move the window, and each component can perform a smooth opening and closing operation.

[0083] The body forms the main structure of the window opening and closing device and can perform the function of supporting the window. The coupling part is connected to one side of the body and can perform the function of fixing the window opening and closing device to the window by coupling with the side of the first window. Through this, the window opening and closing device can operate stably as it is integrated with the window, and the coupling part can provide stable support force when the window is opened or closed. The moving part is formed in a form in which a portion protrudes from one side of the body facing the second window, and can serve to move either the first window or the second window by utilizing frictional force with the second window. The moving part can be connected to a driving device and configured to smoothly open and close the window in a horizontal direction, and can include a mechanism for controlling frictional force to minimize unnecessary resistance during window opening and closing. Additionally, the moving part can be controlled so that the window moves at a predetermined speed and can include a function to adjust the window opening and closing speed as needed. The window opening and closing system of the present invention can be designed to automatically open and close the window without user intervention and can provide structural stability so that the window moves smoothly along a certain trajectory. Through this, the window opening and closing device can effectively regulate the indoor environment and perform functions that contribute to energy saving and security maintenance.

[0084] Referring to Fig. 8, in step S801, an environmental suitability score can be calculated to comprehensively consider indoor and outdoor environmental conditions. The environmental suitability score can be calculated based on the difference in indoor and outdoor temperature, humidity, fine dust concentration, and carbon dioxide concentration. For example, the greater the difference in indoor and outdoor temperature, the greater the need to open windows for ventilation, so the environmental suitability score may increase. On the other hand, if the difference in humidity between the indoors and outdoors exceeds a set threshold, the score is lowered to prevent indoor condensation. If the difference in carbon dioxide concentration is large, the score increases because the need for ventilation increases; conversely, if the indoor fine dust concentration is lower than the outdoor concentration, the score for opening windows is reduced to prevent the influx of contaminated outside air. Based on these environmental suitability scores, the system can determine whether it is appropriate to open the windows under current conditions.

[0085] More specifically, the window opening and closing system of the present invention can calculate an environmental suitability score by comprehensively analyzing indoor and outdoor environmental data and automatically determine whether to open or close the window based on the score. The environmental suitability score is an indicator that evaluates whether indoor and outdoor environmental conditions are suitable for opening or closing the window, and can be calculated by considering factors such as the difference in indoor and outdoor temperature, the difference in humidity, the difference in fine dust concentration, and the difference in carbon dioxide concentration.

[0086] The environmental suitability score serves as a criterion for determining whether the indoor environment can be improved by opening and closing windows by comprehensively evaluating indoor and outdoor air quality. The method for calculating the environmental suitability score and the method of application applied in this invention are described in detail as follows.

[0087] The window opening and closing system of the present invention can calculate an environmental suitability score to determine whether to open or close the window by comprehensively analyzing indoor and outdoor environmental conditions. The environmental suitability score can be determined by considering the difference in indoor and outdoor temperature, humidity, fine dust concentration, and carbon dioxide concentration, and by comprehensively analyzing these factors, the impact of opening or closing the window on improving the indoor environment can be evaluated. The environmental suitability score can be calculated in real time, and if it exceeds a specific threshold, the system can operate to open or close the window.

[0088] The indoor-outdoor temperature difference can serve as an important criterion in the process of calculating the environmental suitability score. Generally, the greater the temperature difference, the greater the need to regulate the indoor temperature by opening windows; therefore, a larger temperature difference can lead to an increase in the environmental suitability score. However, if the indoor-outdoor humidity difference exceeds a threshold, the likelihood of condensation increases; in such situations, the environmental suitability score can be reduced to restrict window opening. For example, in winter when the indoors are warm and the outdoors are very cold, opening the windows can cause condensation to form on the window surface due to the rapid temperature change. Accordingly, this system can restrict window opening even if the indoor-outdoor temperature difference is large, provided that the humidity difference exceeds a set threshold.

[0089] Furthermore, the difference in carbon dioxide concentrations between indoor and outdoor environments can be a significant factor in evaluating the necessity of ventilation. If indoor carbon dioxide levels are high and outdoor levels are low, ventilation is required, which increases the environmental suitability score and may lead to window opening. Conversely, if outdoor fine dust concentrations are higher than indoor levels, there is a possibility that contaminated outdoor air will enter the indoor space, potentially decreasing the environmental suitability score. For instance, on days with high fine dust concentrations, opening windows may actually worsen indoor air quality, necessitating restrictions on window operation. This system can operate by analyzing fine dust concentrations in real time; it permits window opening when indoor air quality is better than outdoor quality and restricts it when the opposite is true.

[0090] The environmental suitability score can also reflect wind speed data. Since opening windows when external wind speeds are strong increases the likelihood of a rapid influx of fine dust into the interior, the environmental suitability score can be reduced to restrict window opening if wind speeds exceeding a certain threshold are detected. Conversely, if the indoor-outdoor temperature difference is negative (meaning the interior is warmer than the exterior) and the external wind speed is low, the environmental suitability score can be increased to encourage window opening, as natural cooling effects can be utilized. For example, during the summer, if the outdoor temperature is lower than the indoor temperature and the wind is calm, opening the windows can be expected to reduce the cooling load. This system can determine the optimal window opening state to improve the indoor environment by comprehensively considering these conditions.

[0091] The window opening and closing system of the present invention can automatically determine whether to open or close a window by analyzing indoor and outdoor environmental data in real time and dynamically adjusting the environmental suitability score. Through this, indoor air quality can be optimized without user intervention, and by appropriately responding to changes in the external environment, it is possible to save energy and maintain a comfortable indoor environment.

[0092] If the temperature difference is within a specific range, natural cooling or heating effects can be expected through opening and closing the windows, thereby increasing the environmental suitability score. Conversely, if the temperature difference is too large, energy loss for cooling or heating may occur, which lowers the score and may restrict opening and closing.

[0093] For example, if the indoor temperature is higher than the outdoor temperature and the difference between the indoor and outdoor temperatures is within a certain range (e.g., 3 to 7°C), the indoor air can be naturally cooled by opening the windows. Conversely, if the indoor temperature is lower than the outdoor temperature (i.e., the outdoor temperature is colder in winter), opening the windows may impede the indoor heating effect, so opening and closing are restricted.

[0094] The window opening and closing system of the present invention is configured to determine whether to open or close a window by considering the difference in humidity between the inside and outside. The difference in humidity is an important factor in evaluating the impact of window opening and closing on the indoor environment, and can be utilized, in particular, to prevent condensation.

[0095] If the humidity difference exceeds a certain threshold, the likelihood of condensation forming on the indoor window surface increases. Accordingly, the system can suppress window opening by reducing the environmental suitability score when the humidity difference exceeds a specific threshold.

[0096] For example, if indoor humidity is 70% or higher and outdoor humidity is 40% or lower, opening the windows can help regulate indoor humidity as indoor moisture escapes. On the other hand, if outdoor humidity is higher than indoor humidity, opening the windows allows outdoor moisture to enter the room, increasing the likelihood of condensation, so the window opening score is lowered to restrict opening.

[0097] The window opening and closing system of the present invention evaluates indoor air quality by utilizing the difference in indoor and outdoor fine dust concentrations and can reflect this in the decision of whether to open or close the window.

[0098] If the outdoor fine dust concentration is lower than the indoor concentration, opening the windows allows fresh air to enter, so the environmental suitability score is increased to raise the likelihood of opening. Conversely, if the outdoor fine dust concentration is higher than the indoor concentration, opening the windows may worsen indoor air quality, so the score is lowered to restrict opening.

[0099] For example, if the indoor fine dust concentration is 50 µg / m³ and the outdoor fine dust concentration is 30 µg / m³, the opening score is increased to purify the indoor air by opening the windows. However, if the outdoor fine dust concentration is 80 µg / m³ and the indoor fine dust is 40 µg / m³, the opening score is lowered to restrict window opening because there is a high possibility that contaminated outside air will enter.

[0100] The window opening and closing system of the present invention evaluates the need for indoor ventilation by utilizing the difference in carbon dioxide concentration between the indoor and outdoor environments, and can reflect this in the decision regarding whether to open or close the window. In indoor environments with high carbon dioxide concentrations, air quality deteriorates, leading to a decrease in oxygen concentration and potentially causing reduced concentration and fatigue. Accordingly, the system of the present invention adjusts the environmental suitability score to induce window opening when the indoor carbon dioxide concentration exceeds a specific threshold.

[0101] For example, if the indoor carbon dioxide concentration is 1200 ppm and the outdoor carbon dioxide concentration is 400 ppm, the outdoor air quality is better, so it is necessary to open the windows to purify the indoor air. On the other hand, if the outdoor carbon dioxide concentration is high at 800 ppm, the difference in indoor and outdoor air quality is not significant, so the opening can be limited by adjusting the opening / closing points.

[0102] Referring to FIG. 8, in step S803, the window opening and closing system of the present invention calculates an energy saving score (W_energy) to minimize energy consumption according to changes in the indoor and outdoor environment, and optimizes whether to open or close the window based on this. The energy saving score can be determined by considering the temperature difference and humidity difference between the indoor and outdoor environments, and the opening and closing of the window can be automatically adjusted to prevent unnecessary waste of heating and cooling energy. Through this, the amount of energy required to maintain the indoor temperature can be reduced, and the load on the HVAC system can be minimized to improve energy efficiency.

[0103] The energy saving score can be designed to decrease as the temperature difference between the inside and outside increases. A large temperature difference means that more heating and cooling energy is required to maintain the indoor temperature; in such cases, opening windows allows heated or cooled air to escape, resulting in energy loss. For example, if the indoor temperature is 22°C and the outdoor temperature is 5°C in winter, opening the windows causes heating energy to escape, potentially leading to the consumption of additional heating energy to maintain the indoor temperature. Conversely, if the indoor temperature is 26°C and the outdoor temperature is 22°C in summer, opening the windows allows for the utilization of natural cooling effects, which increases the energy saving score and incentivizes the opening of the windows.

[0104] In addition, the difference in indoor and outdoor humidity can also affect the energy saving score. Since a large difference in indoor and outdoor humidity may increase the load on the HVAC system, this system can restrict window opening by reducing the energy saving score if the humidity difference exceeds a threshold. For example, if the indoor humidity is 50% and the outdoor humidity is 80% in the summer, opening the windows increases the likelihood of high-humidity air entering the room, which may increase the load on the dehumidifier to remove it. Conversely, if the indoor humidity is 40% and the outdoor humidity is 20% in the winter, opening the windows can induce a natural humidification effect, which increases the energy saving score and may allow the windows to be opened.

[0105] The system of the present invention can more precisely adjust the impact of window opening and closing on energy saving by linking with an HVAC system. When the HVAC system is in operation, if there is a large difference between the indoor and outdoor temperatures, the opening of windows can be restricted to prevent heating or cooling energy from being lost to the outside; conversely, when the HVAC system is turned off, windows can be opened considering the difference between the indoor and outdoor temperatures to maximize the use of natural cooling or heating effects. For example, if the indoor temperature is 24℃ and the outdoor temperature is 18℃, if the HVAC system is in operation, window opening can be restricted to prioritize maintaining the indoor temperature, whereas if the HVAC system is turned off, windows can be opened to utilize the natural cooling effect.

[0106] This system also utilizes AI-based learning capabilities to analyze users' opening and closing patterns and energy consumption data, enabling the automatic application of optimal opening and closing strategies under specific time periods or environmental conditions. For example, if a user exhibits a pattern of opening windows during specific times, the AI ​​can adjust the energy saving score to allow window opening during those periods. This allows window opening and closing to be optimized for energy savings without user intervention, while minimizing unnecessary energy consumption and maintaining a comfortable indoor environment.

[0107] The window opening and closing system of the present invention calculates an energy saving score based on the temperature and humidity differences between the inside and outside, and can automatically determine whether to open or close the window based on this score. Furthermore, by integrating with an HVAC system to minimize heating and cooling loads and utilizing AI learning functions to reflect the user's opening and closing patterns, the system can maximize energy saving effects. Through this, the system can reduce unnecessary energy consumption while effectively maintaining the indoor environment, and can contribute to long-term energy cost reduction and environmental protection.

[0108] An energy saving score is calculated separately to evaluate the impact of opening and closing windows on the building's heating and cooling energy consumption. Since opening windows in situations where there is a large difference between indoor and outdoor temperatures can result in heating and cooling losses, the energy saving score is lowered in such cases to prevent windows from being easily opened. Similarly, if an increase in the load of the HVAC system is expected when windows are opened due to a large difference in humidity, the score is adjusted to suppress unnecessary window opening. The window opening and closing system of the present invention can operate in conjunction with an HVAC (heating, ventilation, and air conditioning) device and analyzes in real time the impact of opening or closing windows on indoor temperature control and energy consumption.

[0109] The window opening and closing system of the present invention can evaluate the impact of indoor and outdoor temperature and humidity differences on indoor energy consumption. If opening and closing the window is highly likely to cause energy loss, the energy saving score can be reduced to restrict window opening; conversely, if opening and closing the window contributes to naturally regulating the indoor environment, the score can be increased to encourage window opening.

[0110] Since the likelihood of heating and cooling energy loss due to opening and closing windows increases with a larger temperature difference, this system can be designed to reduce the energy saving score as the temperature difference increases. For example, if the indoor and outdoor temperature difference is small (e.g., 3°C or less), there is no change in the score because the impact of opening and closing windows on energy saving is minimal; however, if the indoor and outdoor temperature difference is in the range of 5 to 10°C, the score may gradually decrease as there is a possibility of heating and cooling loss. Furthermore, if the indoor and outdoor temperature difference is 10°C or more, the score may decrease sharply to restrict window opening due to the high likelihood of significant heating and cooling energy loss.

[0111] For example, when the indoor temperature is 22°C and the outdoor temperature is 5°C in winter, the system may limit opening by reducing the energy saving score because there is a high likelihood of heating energy loss when the window is opened. On the other hand, when the indoor temperature is 28°C and the outdoor temperature is 24°C in summer, the system may encourage opening the window by increasing the energy saving score because natural cooling effects can be expected.

[0112] This system analyzes the difference in indoor and outdoor humidity to evaluate the impact of opening and closing windows on the increase in HVAC load. More specifically, when the difference in indoor and outdoor humidity is small (e.g., 10% or less), the impact of opening and closing windows on the HVAC load is minimal, so there may be no change in the score. When the difference in indoor and outdoor humidity is 20% or more, the likelihood of an increase in the load of dehumidifiers / humidifiers increases, which may lead to a decrease in the score. Additionally, when the difference in indoor and outdoor humidity is 30% or more, the likelihood of increased energy consumption of the HVAC system due to opening and closing windows increases, so window opening may be restricted.

[0113] For example, in the summer when indoor humidity is 50% and outdoor humidity is 80%, opening the windows may increase indoor humidity and potentially increase the cooling load; therefore, this system can limit window opening by reducing the energy saving score. Conversely, in the winter when indoor humidity is 40% and outdoor humidity is 20%, opening the windows can be expected to provide a natural humidification effect, so it can encourage window opening by increasing the energy saving score.

[0114] Referring to FIG. 8, in step S805, the window opening / closing system of the present invention can determine whether to open or close the window by calculating a security score, thereby reducing the risk of external intrusion and enhancing the security of the window by considering the user's absence. The security score can be adjusted in real time by analyzing the user's location information, time of absence, and the operating status of the window opening / closing device, and if the security score falls below a certain threshold, the opening of the window can be restricted or additional security measures can be executed. Through this, the window opening / closing system can perform smart control functions for security enhancement beyond simple ventilation functions.

[0115] The security score can be configured to decrease as the user's absence lengthens. Since the likelihood of windows being left open poses a security risk increases as the user is away from home for longer periods, the system can take this into account and gradually reduce the security score. For example, the security score may decrease slightly after 30 minutes of absence, and may be lowered further if the user is absent for more than 3 hours. Additionally, if the user is away for more than 6 hours or is absent for an extended period, the security score may be drastically reduced to restrict window opening and enhance security.

[0116] This system can also be designed to determine whether to open or close windows based on the user's location information. To this end, GPS data is collected from the user's smartphone or similar devices, allowing the security score to be gradually reduced as the user moves further away from the location where the window opening / closing device is installed. For example, the security score may be maintained if the user is within 500m, but it may be reduced if the user is more than 1km away, and window opening may be restricted if the user is more than 5km away. This prevents windows from being unnecessarily opened when the user is away from home and at a long distance, and enhances security by automatically closing the windows during prolonged absence.

[0117] This system can be configured to detect abnormal opening or closing attempts by sensing the operating status of the window opening / closing device in real time. If a higher-than-expected load is detected on the moving part of the window opening / closing device without a user operation command, the system may determine this as an attempt at forced opening and drastically reduce the security score. For example, if a load higher than the normal opening / closing torque value occurs, this may be considered an attempt by an external intruder to forcibly open the window; consequently, the security score may be significantly lowered, and window opening / closing may be restricted. Furthermore, if abnormal opening / closing is detected, the system may immediately send a notification to the user or activate a security alarm system. Additionally, it may be configured to increase the minimum opening / closing torque value of the moving part to prevent the window from physically moving, thereby making it more difficult to forcibly open the window.

[0118] The window opening and closing system of the present invention evaluates the impact of window opening and closing on security by adjusting the security score in real time, and can automatically determine whether to open or close the window based on this. It can be designed to adjust the security score by reflecting the user's absence time and location information, and to automatically perform security measures by detecting unexpected attempts to open or close the window. This prevents windows from being unnecessarily opened while the user is away or at night, and minimizes the risk of external intrusion. Furthermore, if an attempt at forced opening or closing is detected, the security score is immediately reduced and window opening / closing is blocked to enhance security. Through these functions, the present system can address the security vulnerabilities of existing window opening and closing methods and enable safer window management in a smart home environment.

[0119] The longer the user is away from home, the lower the security score automatically becomes, and the security level can be dynamically adjusted by utilizing GPS information from the user's smartphone to determine the user's current location and absence.

[0120] If the load on the motor of the window opening / closing device exceeds the expected opening / closing torque value, the system detects this as an abnormal attempt to open or close the window and can immediately restrict or stop the window's movement. In particular, if such an abnormal attempt occurs at night or when the user is away, the alarm system activates to send a notification to the user and, if necessary, activates surrounding warning lights or sirens to take additional security measures. Through these enhanced security features, the window opening / closing system increases safety and protects the living space even when the user is absent.

[0121] For example, the longer the user is absent, the lower the security score may decrease. If the user leaves within 30 minutes, there is no decrease in the security score, and if the user is absent for more than 1 hour, the security score may decrease slightly. If the user is absent for more than 3 hours, the security score may decrease due to increased security risks associated with opening and closing windows. If the user is absent for more than 6 hours, the security score may decrease sharply to restrict window opening. This system can be designed to detect cases where windows are opened or closed without a user operation command and immediately decrease the security score.

[0122] In an embodiment of the present invention, if an excessive load is detected on the moving part, it is determined that the window is abnormally opened or closed, and the security score can be reduced. If a load higher than expected is detected on the moving part of the window opening / closing device, it is determined that there is an attempt to forcibly open the window, and the security score can be reduced. For example, if a load higher than the normal opening / closing torque value is detected, there is a possibility that the window may be forcibly opened from the outside, so the security score can be drastically reduced to restrict window opening.

[0123] This system can be configured to increase the minimum operating torque value of the moving part to more firmly secure the window when an attempt at forced opening or closing is detected. This prevents the window from opening easily when a forced opening attempt is made.

[0124] Based on the technical implementation method described above, the window opening and closing system of the present invention can automatically control the opening and closing of windows by comprehensively considering environmental changes, energy saving requirements, security situations, and user patterns. As a result, it provides various benefits, such as improving indoor air quality and comfort, increasing building energy efficiency, and ensuring safety from external intrusion, while minimizing user intervention. These features are the main advantages of the window opening and closing device of the present invention, enabling the realization of a more intelligent and efficient window management system by overcoming the limitations of conventional technology.
