Description

Technical Field

[0001] The invention relates to the technical field of intelligent window sashes, and in particular to an electric window opener. Background Art

[0002] The inward opening and tilting window is a window that can be opened 90 degrees vertically to the room, or opened horizontally downward to a small angle for ventilation. The inward opening and tilting window is operated by operating the window handle to drive the corresponding movement of the hardware actuator, so that the window can be opened horizontally to the room or tilted to a certain angle for ventilation. The inward tilting position is another opening method of the casement window, which allows the room to circulate with the air of nature naturally, and the indoor air is fresh, while eliminating the possibility of rainwater entering the room. Fresh air undoubtedly creates a comfortable living environment for people.

[0003] The machine used to open and close windows is called a "window opener" or "window opener". It is generally called a "window opener" abroad, and is mostly called a "window opener" in China. It is now a new technology product in the domestic construction industry, and "intelligent electric windows" are the latest development in the modern window industry.

[0004] At present, electric window openers are mainly chain-type, and this type of window opener is self-locking. After installing an electric window opener on a traditional window, the user can no longer manually control the opening and closing of the window sash. The window sash is completely controlled by the electric window opener, and the original handle, transmission box and window lock will become invalid. The self-locking feature of the window opener replaces the hardware structure lock of the window sash. The window sash cannot be locked with the original hardware, and the safety of the window sash will be greatly reduced. The functions of traditional electric window openers are also limited, and they can only simply open or close the window. When installed on a multi-functional system window (top-hung, tilt-in, casement, etc.), the window opener cannot realize all the functions of the system window because it cannot control the window handle for control.

DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] See also Figures 1 to 23 , the present invention provides a technical solution:

[0055] A window fan electric control system, such as Figure 1 As shown in the figure, the system structure diagram shows the linkage modes of various electrical equipment. The linkage equipment listed in the system includes electric curtain window parts, electric window openers, electric window sash handles, indoor air purifiers, fresh air systems, indoor exhaust systems, air quality detectors (indoor), air quality detectors (outdoor), wind sensors, light sensors and rain sensors; the control equipment includes mobile phone APP, radio frequency remote controller 1 and radio frequency remote controller 2; the network communication and linkage are composed of servers, home routers and smart gateways.

[0056] Users can control the electrical equipment in the system through the mobile phone APP and RF remote control. Air and environmental parameters can be set in the App, and the system will automatically adjust the linkage work plan of the electrical equipment according to the connected devices. The APP will send the linkage plan to the smart gateway through the network, and the smart gateway will start the linkage control work after storing the plan.

[0057] The advantage of this system is that it can be disconnected from the Internet for linkage control for special purposes, which is more convenient to use. Compared with the traditional way of controlling windows, the electric window handle is added to control the window more reasonably. For system windows, the way of opening the window can be switched, and the original hardware on the window can be used to lock the window. There is no need to modify the structure of the window, which is safer.

[0058] In this system, the intelligent gateway has an independent control system, and the system can also be controlled in linkage when not connected to the Internet. The windows are equipped with electric window openers and electric window handles for combined operation, making the control of the windows more reasonable.

[0059] This system is based on the control of the opening and closing of the window sash by the electric window opener. Compared with the current existing technology, which is relatively simple and can only achieve relatively simple and single-function linkage work, and the key equipment in the system, the window opener, has many shortcomings, so as to create an intelligent control system for adjusting the indoor environment, which can achieve or approach the required indoor environment without manual intervention. At the same time, in view of the shortcomings of the existing window opener technology, a better structural control solution for windows is proposed.

[0060] This system is a control system based on the window opener, covering some electrical equipment that can work in conjunction with the window opener. This system is suitable for adjusting various indoor environments and provides convenience for production and life.

[0061] Specifically, the electric handle realizes the linkage between the window sash transmission hardware and the electric window opener, which greatly simplifies the process of electric transformation of traditional window sashes. This control system combines a variety of external electrical equipment around electric windows, can support a variety of linkage working schemes, and can provide convenience for life.

[0062] Among the above components, except for the electric window opener and the electric window sash handle, all of them can be based on existing technologies. For example, the electric curtain window part is based on the electric opening and closing curtain series and the electric lifting curtain series composed of motors, controllers, pulleys, belts and other components, which are automatically unfolded and retracted window curtains. The following is a further description of other components in the system:

[0063] 1. The role of the gateway: In the entire smart home system composed of multiple devices, the role of the gateway is actually very similar to that of the wireless router. Both are responsible for communication across different network segments and protocols, similar to what people call a "translator". The difference is that the router is the underlying support for building the wireless WiFi hotspot LAN within the entire home, and is a networking device between the intranet (LAN) and the external network (Internet) or the upper network segment, while the gateway is a data transfer device between different transmission protocols in the intranet. Several common wireless connection methods for smart homes include WIFI, Bluetooth, zigbee, and RF 315 / 433.

[0064] (1): RF 315 / 433 is the earliest and most common solution used in the field of smart home. It is simple in design and low in cost, but its fatal weakness is that it cannot provide two-way real-time feedback communication. That is to say, after the control signal is sent, it cannot reflect the status of the controlled device in real time. It is destined to be eliminated. (2): The characteristics of WiFi are that it has many devices, a wide range, and a fast speed, but it consumes a lot of power and is not suitable for low-power sensors. The characteristics of Bluetooth are low power consumption, good stability, and open protocol, but it is troublesome to form multiple networks, and it is usually one-to-one. (3): ZigBee technology is a short-range, low-complexity, low-power, low-speed, and low-cost two-way wireless communication technology. ZigBee can work at 2.4GH (global), with a maximum of 250Kbit / s and a minimum of 20Kbit / s. The transmission distance is between 10-75M. ZigBee's security is recognized to be relatively good, using AES-128 encryption. In addition, ZigBee networks have strong self-organizing and self-healing capabilities.

[0065] 2. What are Bluetooth Low Energy (BLE) and Bluetooth Gateway? Bluetooth Low Energy (BLE), also known as Bluetooth Low Energy, is a personal wireless LAN technology. Compared with the classic Bluetooth used in mobile phones, headphones, TVs, PCs or audio devices, it has lower power consumption and longer transmission distance, and is mainly used in some battery-powered smart home devices. Due to considerations such as power consumption, cost, and security, BLE sub-devices usually do not integrate WiFi modules themselves, so they cannot be directly connected to routers and external networks independently, and they also need the help of Bluetooth gateway devices to achieve this.

[0066] 3. What are Zigbee transmission protocol and Zigbee gateway? ZigBee, also known as Purple Bee, is a low-speed, short-distance transmission wireless network protocol. Its main features are low speed, low power consumption, low cost, support for a large number of network nodes and multiple topological structures.

[0067] 4. Why don't you connect to the router directly via WiFi, but need to use a gateway for transfer? If all devices are connected to the router directly via WiFi, without using a gateway for data transfer, it is definitely feasible in theory. But for the entire smart home system network, if only a few devices are involved, there will be no problem. However, with the continuous increase of various new devices, it will inevitably bring many obvious problems: First, if the entire network has only one router hub, it may not be able to support such a large number of devices. Moreover, although WiFi has stronger transmission capabilities, there will be dead spots and blind spots for houses with larger areas and multiple rooms. Even if there is no limit on the number of devices connected to the router, and perfect WiFi coverage without dead spots in the whole house, too many devices connected and transmitting are likely to cause congestion and interference, which will affect the operating efficiency and actual experience of the entire network; secondly, the power consumption of devices using WiFi transmission will also increase, which will make more devices unable to work independently without the constraints of power cords. Even if larger capacity batteries are used, they will need to be replaced or charged frequently, which will cause huge limitations and impacts on device size, research and development difficulty, maintenance cost, flexibility and convenience, etc.; and if all transmission processes are handed over to WiFi, routers and external networks to complete, and There is only one data exchange center in the network. Once there is a problem with it, all controls and scenarios will not be realized. This means that all switches that rely on WiFi transmission, security deployment and other equipment linkage will be useless. For smart devices with high security requirements such as fingerprint locks, if they are directly connected to the intranet and extranet through WiFi, even if more advanced encryption transmission protocols and processes are used, they will bring fatal potential security risks, and the risk of illegal monitoring, tampering and control will be greater. More importantly, if all devices are implanted with WiFi transmission chips, the R&D costs and hardware expenses will gradually increase, and the deployment budget and threshold of smart homes will also increase accordingly. In addition, the command transmission messages between some devices and routers are usually only a few KB, which is also a waste of WiFi communication capabilities. In summary, only the use of gateways and multi-protocol transfers to realize device data transmission and exchange is the most efficient and feasible solution in smart home systems at present and for a long time in the future. With the gradual popularization of Zigbee 3.0 and Bluetooth gateway technology, it is believed that multi-mode gateways will become an indispensable and important hardware component in the deployment and upgrade of future smart home systems, and can reflect and play a more outstanding core value and practical role.

[0068] 5. Common smart home products with built-in communication chip models: Depending on the function of the product, the product has different requirements for network communication. Products with low power consumption, large quantity and small data volume often use radio frequency, Bluetooth and zigbee modules. Products with large data transmission volume often use WiFi modules for data transmission. Electric curtains: Electric curtains need to meet the user's outdoor remote network control and indoor short-range remote control. When remotely connected to the network, it generally contains a large amount of data information such as opening size and timed switch. Therefore, general products have both WiFi and radio frequency modules. The WiFi module is usually ESP8266, and the radio frequency module is usually CC1101 wireless module (433MHz). Electric window opener: Electric window opener needs to meet the user's outdoor remote network control and indoor short-range remote control. When remotely connected to the network, it generally contains a large amount of data information such as window sash opening size and timed switch window. Therefore, general products have both WiFi and radio frequency modules. The WiFi module is usually ESP8266, and the radio frequency module is usually CC1101 wireless module (433MHz). Electric window handle: Electric window handle needs to meet the needs of outdoor remote network control and indoor short-range remote control. When remote network control is performed, it generally includes a large amount of data information such as window mode (inward tilt, inward opening, locking) and timed window opening and closing. Therefore, the general product has both WiFi and RF modules. The WiFi module is usually ESP8266, and the RF module is usually CC1101 wireless module (433MHz). Air treatment device: Air treatment device generally needs to meet the needs of outdoor remote network control. When remote network control is performed, it generally includes a large amount of data information such as working air volume gear, timed switch air treatment function, and uploading air quality data. This type of product generally has a control panel, so the product usually only has a WiFi module. The WiFi module is usually ESP8266. Air detection device: For example, an air quality detector (CN201920582419.0) is a new type of air detection device with a WiFi module inside. It can send the detected air quality and other data to the user through the network in real time, and can also transmit data to the smart home control system. The smart home control system can control the operation of smart home devices based on these data, thereby achieving automatic improvement of the environment. The WiFi module is usually ESP8266. Wind, light and rain detection device: The wind, light and rain detection device usually sends simple data to the outside. The product works outdoors, so it does not use external power supply and is usually powered by an internal battery. Its low-power product positioning determines its communication method, so the product usually only has a Bluetooth module. The Bluetooth module is usually NRF51802.

[0069] 6. Multi-function gateway chip solution: ZigBee: The multi-function gateway uses an industrial-grade ZigBee RF chip (JN5168) based on NXP for networking communication; WiFi: ESP-12F; Bluetooth: HC-05; RF: CC1101 (433MHz).

[0070] In this system, the electric window opener is a device used to control the opening and closing of the window sash. When this electric window opener is used for an inward opening and tilting window, the window sash can be tilted inward, opened inward, and locked. When used for a casement window, the window sash can be opened and locked.

[0071] As shown in 2-3, the upper cover plate 1 and the housing 2 are assembled by screws A5; the front panel 3 and the housing 2 are assembled by screws C7; screws B6 are used to fix the main body of the electric window opener on the window frame 22; electromagnetic clutch 8, motor 9, gear set 10 and circuit board 12 are installed in the housing 2; motor 9 is used to provide power to push the window sash (window sash frame 22); gear set 10 is used to convert the power provided by motor 9, reduce the speed and increase the torque; electromagnetic clutch 8 is used for the rigid and flexible connection of gear set 10 and connecting rod A11. When the electromagnetic clutch 8 is powered on, the gear set 10 and connecting rod A11 are rigidly connected. At this time, the motor 9 can drive the connecting rod A11 through the gear set 10 to drive the window sash to move, and manual opening and closing of the window sash is not allowed. When the electromagnetic clutch 8 is powered off, the gear set 10 and connecting rod A11 are flexibly connected. At this time, there is a weak damping force between the gear set 10 and connecting rod A11. The damping force is used to prevent the window sash from swinging due to wind force. At this time, manual opening and closing of the window sash is allowed. When the electric window opener receives the window opening and closing signal, the electromagnetic clutch 8 is energized, and when the window opening and closing action is completed, the electromagnetic clutch 8 is de-energized; the screw D16 is used to fix the guide rail 17 on the window frame 41; the slide block 18 is installed on the guide rail 17, and the slide block 18 can slide on the guide rail 17; the connecting rod A11 is connected to the connecting rod B15, and the other end of the connecting rod B15 is connected to the steering connecting rod 19 through the cross shaft 20. Figure 4-12 As shown in the "window opener inward opening / tilt / locked mode status", the multi-section connecting rod multi-axis structure realizes the perfect adaptation of the inward-tilt and inward-opening windows.

[0072] As shown in Figure 2, there are WiFi module (ESP8266) 13 and radio frequency module (433MHz) 14 on the circuit board 12. The WiFi module 13 is used for network control of the electric window opener. The WiFi module 13 can be directly connected to a router or to a smart gateway to achieve more advanced linkage control. The radio frequency module 14 is used for short-range remote control of the electric window opener. The remote control device for the electric window opener can be an 86 panel radio frequency remote control or a mobile handheld remote control, that is, Figure 1 RF remote control Ⅱ.

[0073] When the electric window opener is opened or closed by remote control via a mobile phone APP or a radio frequency remote control II, when the connecting rod B15 is extended or retracted into place, the current of the motor 9 increases, and at this time, the circuit board detects it, thereby controlling the power-off and stop of the motor 9.

[0074] The above electric window opener, in the open / tilt / lock mode state in the window opener, has a motion state as follows Figure 10-12 As shown, the left side is a vertical diagram, and the right side is a diagram obtained by viewing from point A in the vertical diagram. Compared with the current electric window openers, which are mainly chain-type, this type of window opener is self-locking. After the traditional window is installed with an electric window opener, the user can no longer manually control the opening and closing of the window sash. The window sash is completely controlled by the electric window opener, and the original handle, transmission box and window lock will become invalid. The self-locking feature of the window opener replaces the hardware structure lock of the window sash. The window sash cannot be locked by the original hardware, and the safety of the window sash will be greatly reduced. The functions of the traditional electric window opener are also limited, and can only simply open or close the window. When installed on a multi-functional system window (top hanging, inward tilt, flat opening, etc.), the window opener cannot realize all the functions of the system window because it cannot control the window handle for control. The electric window opener has a networking function, and users can remotely control the window opening and closing. At the same time, it makes it more convenient to control the opening and closing of the window. (Users can remotely control the window through the network, or open and close it manually like traditional windows.) Controlling windows is more scientific and reasonable. (The original structure of the window will not be damaged during installation, and the original function and structure of the user will not be affected during use.) This solves the problem of the single window opening mode of the traditional electric window opener. In addition, it solves the problem that the user cannot manually open and close the window sash when a power outage or mechanical failure occurs in the traditional electric window opener. The electric window opener has a multi-link structure and is compatible with both the inward opening and inward tilting modes of the window sash. Its use will not affect the function of the hardware on the window. In the event of a power outage or a mechanical failure of the window opener, the user can manually open and close the window without affecting the structural safety of the window.

[0075] In this system, the electric handle of the window sash is Fig.13 , 14 As shown, its shape is similar to a fingerprint door lock. The handle 24 shown is consistent with the function of the traditional handle and is used to switch the window sash mode; the square shaft 30 is a power output shaft, which is used to drive the hardware transmission box in the window frame 41 to work. The specifications of the square shaft 30 are the mainstream general specifications on the market (cross-sectional size 7*7mm), which is consistent with the traditional handle output shaft, so the hardware transmission box in the window frame 41 does not need to be specially customized, which reduces the use cost of the electric handle of the window sash; the mode lever 25 is used to switch the manual and electric modes of the electric handle of the window sash. When the electric window opener or the electric handle of the window sash fails, the user can turn the mode lever 25 to the manual mode and temporarily manually open and close the window; the panel 28 is provided with a button 26 for switching the switch mode of the window sash (inward opening and tilting window: inward tilting, inward opening, locking; casement window: casement, locking).

[0076] It can be seen from the appearance that the handle 24, the mode lever 25 and the square shaft 30 are movable parts. The square shaft 3 will rotate in the same direction as the handle 24 rotates. The state of the handle 24 varies with the window type, such as Fig.23 The figure shows the handle angle position diagram, which shows the three states of the electric window handle installed on the inward opening and tilting window. When it is installed on the casement window, there is no inward tilting state.

[0077] like Fig.15 As shown, the panel 28 and the housing 29 are assembled by snapping, gluing and magnetic attraction; the handle 24 and the transmission wheel 40 are assembled by the countersunk screw B34, because the transmission wheel 40 has a hexagonal protrusion, which can be inserted into the inner hexagonal groove of the handle 24. At the same time, the other side of the transmission wheel 40 has a square groove, and the square shaft 30 can be inserted into the square groove of the transmission wheel 40. The handle 24, the transmission wheel 40, the countersunk screw B34 and the square shaft 30 are relatively fixed. Therefore, when the user turns the handle 24, the transmission wheel 40, the countersunk screw B34 and the square shaft 30 will rotate synchronously. When the transmission wheel 40 is used as a driving wheel in the electric mode, when the transmission wheel 40 rotates, the handle 24, the countersunk screw B34 and the square shaft 30 will rotate synchronously.

[0078] like Fig.16 As shown, the mode lever 25 has a D-shaped groove, and one end of the mode shaft 36 is a D-shaped shaft. After the mode lever 25 and the mode shaft 36 are assembled, the user can drive the mode shaft 36 by turning the mode lever 25; Fig.17 As shown, under the action of the mode shaft 36, the worm / helical gear 39 meshes with the tooth structure of the transmission wheel 40. At this time, when the reduction motor 37 drives the worm / helical gear 39 to rotate, the transmission wheel 40 will rotate under the interaction of the tooth structure, thereby realizing the electric drive square shaft 30 to rotate; Fig.18 As shown, the position of the mode shaft 36 and the mode lever 25 changes. Under the action of the mode shaft 36 and the tension spring 44, the worm / bevel gear 39 and the tooth structure on the transmission wheel 40 no longer form a meshing relationship. At this time, the user can manually rotate the handle 24 to manually drive the square shaft 30 to rotate.

[0079] like Figure 19-21As shown, when installing the electric window sash handle, you only need to remove the panel 28 and the mode lever 28, plug in the signal line, and install the electric window sash handle on the window sash frame 22 through the countersunk screw C43. Then install the panel 28 and the mode lever 25 to complete the electric window sash handle. Since the installation method of the electric window sash handle is basically the same as the installation method of the traditional manual square shaft handle, the installation and use costs of the electric window sash handle are reduced. On the new window frame, holes are opened according to the standard installation holes for the manual square shaft handle, and a signal line hole is added. On the finished window, the manual square shaft handle is directly removed, and the electric window sash handle signal line hole 42 is added. As shown Fig. 22 As shown in the window frame installation hole diagram in the installation diagram, a common square shaft handle installation hole standard is listed. The electric window sash handle can directly replace the square shaft handle of this standard, but this electric window sash handle is not only applicable to this installation hole standard. Therefore, traditional window manufacturers can use electric window sash handles without spending more money in the window manufacturing process, thereby increasing the value of the window.

[0080] like Fig.17 , 18 As shown, the circuit board 12 has a WiFi module (ESP8266) 13 and a radio frequency module (433MHz) 14. The WiFi module 13 is used for the network control of the electric window sash handle. The WiFi module 14 can be directly connected to a router or to a smart gateway to achieve more advanced linkage control. The radio frequency module 14 is used for short-range remote control of the electric window sash handle. The remote control device for the electric window sash handle can be an 86 panel radio frequency remote control or a mobile handheld remote control, that is, Figure 1 RF remote control Ⅱ.

[0081] When the electric window handle is installed on the inward opening and tilting window, the electric handle can drive the original hardware actuator on the window to switch between the inward opening, inward opening and locking modes. Compared with the traditional electric window, there are no longer two modes of casement opening and locking, so the electric handle can achieve a better inward tilting state.

[0082] The electric window handle can be used alone or in conjunction with the above-mentioned electric window opener: it makes it easier to control the opening and closing of windows. (Users can remotely control windows through the network, or open and close them manually like traditional windows.) Controlling windows is more scientific and reasonable. (The original structure of the window will not be destroyed during installation, and the original function and structure of the user will not be affected during use.) Figure 4 , 6 As shown in FIG. 8, when the electric window opener and the electric window sash handle are installed on the inward opening and tilting window for use, when the window sash frame 22 is changed from the closed state to the open state, the handle 24 needs to be rotated manually or electrically to realize the following operation: Fig.23After the window is in the side-open or inward-tilt state shown, the electric window opener can be opened to realize its corresponding inward-opening or inward-tilt function.

[0083] The form of the electric window handle does not require complicated modification of the window frame, and can be installed in the same way as the traditional square shaft handle. The use of the electric window handle will not affect the function of the hardware on the window, nor will it affect the structural safety of the window. At the same time, the process of switching the window mode (opening, closing) of the electric window handle is changed from traditional manual switching to electric switching. It solves the safety problem of ordinary windows only installing electric window openers, which causes the original handles and hardware to fail.

[0084] The present invention can be applied to the following industries that use inward-opening and inward-tilting windows. For example: high-position windows, windows that are installed at a high or too far position and cannot be reached by manpower alone. The windows are too heavy, and it is laborious to open or close them, and it is inconvenient to use manual switches. Fire smoke exhaust windows on floors that require fire linkage ventilation. There are weather opening / closing window requirements, such as: windows that need to be automatically closed when it rains in warehouses. There are requirements for constant temperature indoors, such as: windows in vegetable or flower greenhouses. There are requirements for indoor temperature, and windows are automatically opened when the temperature is too high, such as: windows in communication rooms. There are strict requirements for indoor air index, and timely and regular ventilation is required. The room needs a more appropriate brightness, which needs to be achieved by adjusting the angle of the blinds. The windows need a stricter closing and sealing force, such as the skylight needs to be closed more tightly to prevent rain. Other special occasions, such as chemical, dust and other factory workshops, require timely ventilation. Green, intelligent, energy-saving modern high-rise buildings, such as curtain wall windows, etc. Building automatic control, smart home control, etc.

[0085] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
