Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The air curtain machine is widely applied to scenes such as markets, theaters, restaurants, subways, refrigerators and the like, separates indoor air and outdoor air through high-speed airflow generated by the operation of the internal fan, and plays roles in preventing indoor and outdoor air exchange, preventing dust, preventing insects and preventing pollution.
However, at present, a user usually customizes the air curtain machine according to the size of the used door, and usually only customizes the air curtain machine installed at the top of the door or the air curtain machine installed at the side of the door, so that the size of the fan inside the single air curtain machine needs to be increased along with the increase of the height of the door, and only the single air curtain machine acts on the area corresponding to the door. This not only consumes energy and is inconvenient to install, but also does not prevent indoor and outdoor air exchange at all once a single working air curtain machine fails. Meanwhile, the air curtain machine is customized and is inconvenient to use for the second time, so that waste is caused, and the applicability is poor.
In addition, the switch that present part air curtain opportunity combines the door opens and stops control, reaches energy-conserving purpose, promptly: when people pass through, the air curtain machine is opened by opening the door; when the person leaves, the door closes the air curtain machine. However, the air curtain machine has low applicability and cannot be used in occasions where the door needs to be normally opened.
In view of the above-mentioned unreasonables of the prior art air curtain machine, the present invention provides an air curtain device, comprising: and each air curtain machine is positioned at different positions on the edge of the same area. In combination with the shape of the door, the air curtain device generally comprises: at least one transverse air curtain machine arranged at the top end of the door and at least one longitudinal air curtain machine arranged at the side of the door. This air curtain device can be freely nimble assemble the use to a plurality of air curtain machines according to the height of door, can be suitable for the door of multiple various sizes. Meanwhile, due to the mode of assembling and using the plurality of air curtain machines, the size of the fan inside the air curtain machine is also reduced, so that the air curtain machine is convenient to mount and dismount.
In addition, the air curtain device provided by the invention is also provided with the sensing device, the sensing device is used for monitoring whether a person approaches a door using the air curtain device in real time, and when the person walks into a preset range, the air curtain device can automatically reduce the rotating speed of the fan, so that the energy is saved, and passers experience is comfortable.
The principles and construction of the present invention will be described in detail below with reference to the drawings and examples.
As shown in fig. 1, the air curtain device according to the present invention includes: a transverse air curtain machine 1, a first longitudinal air curtain machine 2 and a second longitudinal air curtain machine 3. The first longitudinal air curtain machine 2 and the second longitudinal air curtain machine 3 are oppositely arranged and relatively exhaust air, and the transverse air curtain machine 1 is arranged above the first longitudinal air curtain machine 2 and the second longitudinal air curtain machine 3 and exhausts air downwards. The transverse air curtain machine, the first longitudinal air curtain machine or the second longitudinal air curtain machine consists of an air curtain box 8, a fan 5 and an air pipe 6. 6 one end openings of tuber pipe, fan 5 just set up in open end one side, blow to tuber pipe 6 is interior, evenly is equipped with a plurality of exhaust vents side by side along the axial on the side of tuber pipe 6, and the wind that fan 5 blew off just flows out from the exhaust vent. Tuber pipe 6 and fan 5 are all fixed inside air curtain case 8, and fan 5 is fixed with the lateral wall of air curtain case 8, and the blind end of tuber pipe 6 and the end connection of air curtain case 8 are equipped with a plurality of play tuber pipes 7 on the lateral wall of air curtain case 8 simultaneously, go out the position of tuber pipe 7 and the position one-to-one of exhaust vent and intercommunication. The air curtain machine has extremely simple composition, saves materials, simplifies the manufacturing process and is convenient for large-scale production. Meanwhile, when the longitudinal air curtain machines are arranged on two sides of the door relatively, the condition that air outlet air flow possibly generates convection is considered, air outlet pipes of the longitudinal air curtain machines which are located at opposite positions are staggered mutually when the longitudinal air curtain machines are installed, and the air outlet density is increased to place convection. Therefore, when the first longitudinal air curtain machine and the second longitudinal air curtain machine in the embodiment are designed, the air outlet pipes of the first longitudinal air curtain machine and the second longitudinal air curtain machine are staggered in the vertical direction.
In addition, the displacement sensor 4 is installed inside the transverse air curtain machine 1, the displacement sensor 4 detects the moving distance of an object, a detection distance (the detection distance refers to the distance between the object and the air curtain device) is preset in the air curtain device, and when the object enters the distance range, the controller controls the rotating speed of the fans in the first longitudinal air curtain machine 2 and the second longitudinal air curtain machine 3 to be reduced. When the object moves out of the range of the detection distance, the rotating speeds of the fans in the first longitudinal air curtain machine and the second longitudinal air curtain machine are controlled to be restored to the original state. For example, when the distance between the person and the air curtain device is less than or equal to the detection distance, the controller controls the fans of the first longitudinal air curtain machine and the second longitudinal air curtain machine to rotate at a first rotating speed; when the distance between the living object and the air curtain device is larger than the detection distance, the controller controls the fans of the first longitudinal air curtain machine and the second longitudinal air curtain machine to rotate at a second rotating speed, wherein the first rotating speed is smaller than the second rotating speed. Therefore, when people pass through the air curtain device, better skin feeling experience can be achieved, and meanwhile, the energy-saving effect is achieved.
In other embodiments, the number of the air curtain machines in the air curtain device is not limited, and the user only needs to assemble and use the air curtain device at will according to the needs of the user. The positions of the air outlet pipes on the air curtain machine are not limited to be arranged on a straight line, the positions of the left air outlet pipe and the right air outlet pipe can be staggered in a grid mode, the air outlet pipe on one side is positioned on the upper half part, the air outlet pipe on the other side is positioned on the lower half part, the positions of the left air outlet pipe and the right air outlet pipe are staggered front and back, and the like. The sensing device may be other devices such as an infrared sensor.
