Description

Pre-activated air door

The present invention relates to an air door, especially an air door that uses infrared images to pre-start.

Air door, also called air curtain or damper, is an air-conditioning device that is installed on the entrance and exit door to isolate indoor and outdoor air by airflow. The air door can prevent outdoor dust and heat from entering the room, saving air-conditioning leakage and preventing mosquitoes from entering the room. Although the air door is a goalkeeper for entering and exiting the door, it is very common and convenient because most of the doors of business premises use linkage control switches, that is, when the door is opened, the air door will receive a signal to start blowing. However, there is a problem of time lag for those who want to greatly improve the saving of air-conditioning spills and prevent the entry of flies and mosquitoes.

If you want to reduce the consumption of air-conditioning electricity and more effectively stop outdoor mosquitoes, the best solution is to open the empty door at the time when people enter and leave the door, and close it immediately after people pass the door. In response to this demand, the Republic of China Patent No. M529042 discloses an air door advance sensing device, which is mainly because an air door and an automatic door have an independent circuit respectively, so the air door and the automatic door will not be activated at the same time. The air door starts first and the automatic door starts later. In practice, if you follow the automatic door and then open the air door, before the air door forms an air wall, there will be airflow through the inside and outside of the automatic door, which will bring in mosquitoes and dust, and let the air-conditioning leak out. Such an approach cannot solve the aforementioned problems.

Therefore, in order to effectively solve this problem, the creator of the present invention proposes an innovative pre-activated air door.

This paragraph of text extracts and compiles certain features of the new model. Other features will be revealed in subsequent paragraphs. Its purpose is to cover the spirit and scope of the additional patent application, various modifications and similar arrangements.

In order to solve the aforementioned problems, the present invention discloses a pre-activated air door. The air door is installed above the inner side of an entry and exit door, activated to form an airflow wall inside the entry and exit door, and includes a fan module, a power module that controls the operation of the fan module, and a cover for the two modules. A shell. In addition, it further includes: a first infrared human body sensor installed on the inner fixing object of the entrance and exit door, and when a first distance range from the inner side of the entrance and exit door is detected, a first infrared sensor is emitted. Opening message; a second infrared human body sensor installed on the outer fixed object of the entrance and exit door, when it detects that someone appears within a second distance from the outer side of the entrance and exit door, it sends out a second opening message; and A processing module installed in the housing, connected with the first infrared body sensor, the second infrared body sensor, and the power module electrical signal, when receiving the first opening message or the second opening After the message, control the power module to start the fan module.

The present invention also discloses another pre-activated air door. The air door is installed above the inner side of an entry and exit door, activated to form an airflow wall inside the entry and exit door, and includes a fan module, a power module that controls the operation of the fan module, and a cover for the two modules. A shell. In addition, it further includes: a first infrared human body sensor installed on the housing, when it detects that someone appears within a first distance from the inside of the entrance and exit door, it sends out a first opening message; and a second An infrared human body sensor is installed on the outer fixed object of the entrance and exit door, and when it detects that someone appears within a second distance from the outer side of the entrance and exit door, it sends a second opening message; and a processing module is installed. In the housing, it is connected with the first infrared human body sensor, the second infrared human body sensor and the power module electrical signal, and the power is controlled after receiving the first turn-on message or the second turn-on message The module activates the fan module.

When the first infrared human body sensor detects that no one is present within the first distance from the entrance and exit door, it sends out a first closing message. After receiving the first closing message, the processing module controls the power module The group closes the fan module. When the second infrared human body sensor detects that no one is present within the second distance from the entrance and exit door, it sends a second closing message. After receiving the second closing message, the processing module controls the power module The group closes the fan module.

Preferably, the entry and exit door is an automatic induction door. The first distance and the second distance are greater than an opening distance for the induction automatic door to be opened by induction. The second distance is greater than the first distance.

In another embodiment, the processing module can control the power module to turn off the fan module after a set time.

Since the air door can be opened and closed independently of the entrance and exit doors, in addition to effectively saving power, the independent setting of the second distance and the first distance can also ensure that the air wall is formed before the entrance and exit doors are opened, preventing the leakage of cold air from the inside or the outside Mosquitoes and dust invade.

Figure 1 is a component structure diagram of the pre-activated air door according to the first embodiment of the present invention, Figure 2 shows the installation state of the pre-activated air door, and Figure 3 shows the second embodiment of the present invention The installation state of the pre-activated air door.

The present invention will be described in more detail by referring to the following embodiments.

Please refer to FIG. 1 and FIG. 2. FIG. 1 is a component structure diagram of the pre-activated air door according to the first embodiment of the present invention, and FIG. 2 shows the installation state of the pre-activated air door. The technical components of the pre-activated air door mainly include a fan module 10, a power module 20, a first infrared body sensor 30, a second infrared body sensor 40, a processing module 50, and a壳60。 Housing 60. The types, functions, and mutual operations of the aforementioned technical components will be described below.

As shown in FIG. 2, the pre-activated air door of the present invention is installed above the inner side of an access door 1, such as the wall 2 above the inner side of the access door 1. For the convenience of description, "inside" refers to the side of the entrance and exit door 1 where the pre-activated air door is installed; relatively, "outside" refers to the side of the entrance and exit door 1 where the pre-activated air door is not installed. In Figure 2, the left side of entry and exit door 1 is "inside", and the right side is "outside". The pre-activated air door of the present invention is activated to form an air flow wall inside the entrance and exit door 1, as shown by the hollow arrow in Figure 2. In terms of application, the entrance and exit door 1 can be any kind of door, and people need to prevent dust, mosquitoes, and block the flow of cold air on both sides of the entrance and exit door 1. In this embodiment, a sensor automatic door is taken as an example for illustration. The sensor automatic door uses infrared rays to sense the human body on both sides, and the human body senses to open as soon as it approaches an opening distance. The opening distance varies with the setting of each sensor automatic door, and there is no fixed value.

The fan module 10 in the present invention includes more than one motor, which generates wind flow by interlocking the movement of the fan, which blows to the inner floor of the entrance door 1 (as shown by the hollow arrow in Figure 2), forming an isolated entrance and exit door 1 Airflow walls on both sides. In terms of form, the present invention does not limit the use of any type of fan module 10. The power module 20 controls the operation of the fan module 10. In practice, the power module 20 may include, but is not limited to, a power connection interface (such as a wire connected to a mains plug), a transformer, a control circuit, a power output circuit, and the like. The design of the power module 20 is familiar to the industry. However, the present invention requires the power module 20 to be able to connect with the processing module 50 disclosed in this case. This point will be explained later. The fan module 10 and part of the power module 20 are wrapped in a casing 60 and protected by the casing 60. In addition, the casing 60 also designs an air outlet 61 in cooperation with the fan module 10, which can effectively guide the circulation of airflow and the formation of airflow walls.

The functions of the first infrared human body sensor 30 and the second infrared human body sensor 40 are to detect infrared images emitted by the human body around the environment, so as to determine the location of the human body represented by the image. The difference is that the first infrared body sensor 30 is used to detect people inside the door 1, and the second infrared body sensor 40 is used to detect people outside the door 1. The first infrared human body sensor 30 is installed on the inner fixed object of the entrance and exit door 1. For example, it can be located on the same wall of the wall 2 as the housing 60 or on the wall of the vertical wall 2. In addition, the fixed object can also be other extensions attached to the wall, floor or ceiling. Such as support frame. The purpose of using a fixed object to install the first infrared human body sensor 30 is to find the best detection angle of the first infrared human body sensor 30. As shown in FIG. 2, when the first infrared human body sensor 30 detects the presence of a person (a child 3 shown in FIG. 2) within a first distance L1 from the inside of the entrance and exit door 1, it emits a first opening The message (telecommunications signal) is transmitted to the processing module 50 through the wire. The first distance L1 is the preset inner detection distance of the first infrared human body sensor 30. If the first distance L1 is less than the opening distance, this will cause the induction automatic door to open before the airflow wall is formed, and the air on both sides of the induction automatic door can still circulate, so dust, mosquitoes and air-conditioning will pass. Therefore, in practice, the preset first distance L1 of the first infrared human body sensor 30 should be greater than the opening distance of the sensing automatic door.

In contrast, the second infrared human body sensor 40 is installed on the outer fixed object of the entrance and exit door 1, usually a hole 2a is opened in the wall 2, and a wire is installed in between to connect the second infrared human body sensor 40 and the processing module 50. As shown in FIG. 2, when the first infrared human body sensor 30 detects that a person (child 3 shown in FIG. 2) appears within a second distance L2 from the inner side of the entrance and exit door 1, it emits a second opening The message (telecommunications signal) is transmitted to the processing module 50 through the wire. Similarly, it is preferable that the preset outer detection distance (the second distance L2) of the second infrared human body sensor 40 should be greater than the opening distance of the automatic door.

The processing module 50 is installed in the housing 60 and is connected to the first infrared human body sensor 30, the second infrared human body sensor 40, and the power module 20 for electrical signals. After the processing module 50 receives the aforementioned first turn-on message or the second turn-on message, it controls the power module 20 to activate the fan module 10. In other words, by using the processing module 50 to control some of the power switches in the power module 20, it is possible to switch the fan module 10 with an external infrared human body sensor.

It is impossible for the fan module 10 to remain on after being turned on, which consumes power. Therefore, when the first infrared human body sensor 30 detects that no one is present within the first distance L1 from the door 1, it will send a first closing message. After receiving the first shutdown message, the processing module 50 controls the power module 20 to shut down the fan module 10. Similarly, when the second infrared human body sensor 40 detects that no one is present within the second distance L2 from the entrance and exit 1, it will also send a second closing message. The processing module 50 receives the first 2. After closing the message, the power module 20 is also controlled to turn off the fan module 10. Of course, the fan module 10 can also be set to shut down at a specific time after startup, without being affected by the data of the infrared body sensor. For example, the processing module 50 can control the power module 20 to turn off the fan module 10 after a set time (such as 10 seconds, 30 seconds, or 60 seconds, set according to user needs).

It should be noted that since the main body of the air door is installed on the inner side, if the second distance is the same as the first distance, when someone triggers the opening of the entrance door 1 on both the inner side and the outer side at the same time, the child 3 who enters the entrance door 1 from the inner side will enter than the outer side The old man 4 entering and exiting the door 1 first touches the air wall (assuming that the two move at the same speed). In order to allow people on both sides to form an air wall before entering and exiting the door 1, the second distance should be greater than the first distance.

Please refer to Fig. 3, which shows the installation state of the pre-activated air door according to the second embodiment of the present invention. The structure of this embodiment is similar to the previous embodiment, the difference is that the first infrared human body sensor 30 is installed on the housing 60 instead of on the inner fixed object of the access door 1. It should be noted that the first infrared human body sensor 30 can be installed on the housing 60 or any position in the housing, as long as the detection unit is not shielded by the housing 60. In this way, the effective space inside the original casing 60 of the air door can be utilized, and the dependence on the inner fixing objects of the entry and exit door 1 can be reduced.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the relevant technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, The scope of protection of this new model shall be subject to the scope of the attached patent application.
