Description

Air door with electric ion sterilization and deodorization device

The invention relates to an air door, in particular to an air door with an electric ion sterilization and deodorization device.

Air door, also called air curtain or damper, is an air-conditioning device 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. When the air door is operating, the air drawn in comes from the on-site environment. If the air contains germs (such as hospital waiting rooms, emergency rooms, epidemic prevention hotels, etc.), these germs will continue to circulate and even accumulate in the air door, keeping the indoor space unhealthy. state. In addition, there is also an unpleasant odor in the space, which needs to be removed. In order to reduce the occurrence of the aforementioned situation, air door manufacturers have developed some products with sterilization and deodorization effects.

The easiest way for an air door to have a sterilization effect is to install an ultraviolet sterilization device or an ozone sterilization device in it. These are mature products. However, the ultraviolet rays emitted by the ultraviolet sterilization device are harmful to the human body and consume a lot of machine components. The high odor concentration generated by the ozone sterilization device is not only corrosive and aging to the machine components, but too high ozone content will also cause the human body. There are health hazards, such as coughing and eye irritation. Therefore, the selection of new sterilization methods is the focus of recent air door developers' research and development. The Republic of China Model Patent No. M601105 discloses an air door equipped with a plasma sterilization device, and at least one set of plasma sterilization device is provided at the air outlet of the air door. The plasma sterilization device comprises several grid plates arranged vertically at intervals, and an electrode line with grid plates arranged in parallel is arranged between every two adjacent grid plates. After the grid plate and the electrode wire of the plasma sterilization device are respectively connected with positive and negative electricity, a high-voltage electric field can be generated between the two, so that the air curtain blown out from the air outlet through the plasma sterilization device can be eliminated through the high-voltage electric field And destroy dust mites, bacteria and viruses in the air. Due to the use of high-voltage electric field for sterilization, the plasma sterilization device itself is thick and takes up space, which causes the volume of the air door to become larger, which is not suitable for all fields, and the installation of a device at the air outlet will hinder the blowing effect of the air door itself. Reduce the important function of the product itself to form a wind wall.

Therefore, in order to effectively solve the installation problem of the existing air door plasma sterilization device and provide an effective sterilization effect, there is a new type of air door with an electric ion sterilization and deodorization device.

Since the plasma sterilization device has strong sterilization function and small size, it can be flexibly installed in the narrow space inside the air door of various sizes and different types, so that the sterilization function can be more commonly used in the air door.

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

FIG. 1 is a front view of an air door 1 with an electric ion sterilization and deodorization device according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of the air door 1 with an electric ion sterilization and deodorization device along the section AA′ in FIG. 1. FIG. 3 is a block diagram of the components of the air door 1 with the electric ion sterilization and deodorization device. The air door 1 with an electric ion sterilization and deodorizing device can be installed above the inner side of an entrance and exit door, and activated to form an air flow wall inside the entrance and exit door, which prevents the gas in the space inside the entrance and exit door from leaking to the entrance and exit door through the entrance and exit door The outer space ensures that the air-conditioning air (cold air) entering and exiting the inner space of the door does not flow out, and it can also prevent mosquitoes and flies from entering and exiting the outer space of the door. The technical components of the air door 1 with an electric ion sterilization and deodorization device include a fan module 10, a power module 20 that controls the operation of the fan module 10, at least one electric ion sterilization device 30, and one that covers the aforementioned modules.壳40。 Housing 40. The state, function and overall operation of these technical components will be described in detail below.

The fan module 10 is the most important element of the air door 1 with the electric ion sterilization and deodorization device to generate the air flow wall. Please refer to Fig. 1. For the convenience of description, a part of the center of the intake guide plate 41, which is one of the housings 40 of the air door 1 with the electro-ion sterilization and deodorization device, is removed, so that the inside of the housing 40 can be seen Fan module 10. The fan module 10 includes a driving motor 11 and two cross-flow fan blades 12 connected to the driving motor 11 and driven by it. The two cross-flow fan blades 12 are respectively connected to the rotating shafts 111 on both sides of the driving motor 11, and the driving motor 11 rotates. At this time, each rotating shaft 111 respectively drives a through-flow fan blade 12 to rotate in the same direction. Please see Figure 2. When the fan module 10 is operating, the outside air (shown by hollow arrows) is sucked in by the intake guide plate 41, and continues to rotate inside the housing 40, and finally flows out from the air outlet 42 formed under the housing 40 (the outflow air is Dotted bottom arrow is drawn). In other embodiments, the drive motors of different air doors may only drive one cross-flow fan to rotate, and the fan module of some air doors may also include a combination of multiple fan modules and cross-flow fans. These designs are all In the application of the technical scope of the present invention.

The power module 20 is electrically connected to the fan module 10 and controls the operation of the fan module 10 by switching power supply. The power module 20 may include sub-elements required by the conventional power management architecture, such as a transformer, a power distribution circuit, and an overcurrent prevention circuit, but an important sub-element is the control circuit 21. The function of the control circuit 21 will be described later.

As shown in FIG. 2, the electric ion sterilization device 30 is installed between the air outlet 42 and the fan module 10, and is electrically connected to the power module 10. Turn it on to generate multiple clusters of electrical ions in the surrounding air. These groups of charged ions will wrap and inactivate bacteria or viruses in the airflow flowing out of the air outlet 42. After the clusters of electrical ions attach to the surfaces of viruses and bacteria, under the action of a chemical reaction, they are converted into strong oxidizing reactive oxygen species—hydroxyl groups, thereby taking away the hydrogen from the surface proteins of viruses and bacteria and decomposing them (oxidative decomposition) . The group of electric ions flows along with the airflow into the space near the installation of the air door 1 with the electric ion sterilization and deodorization device, thereby expanding the scope of sterilization. In addition, the group of electric ions can also oxidize odorous chemical components in the airflow flowing out of the air outlet 42 to deodorize them. In this embodiment, an internal airflow guide plate 43 is included between the air outlet 42 and the fan module 10. The function of the internal airflow guide plate 43 is to guide the air sucked into the housing to flow out toward the air outlet 42. The electric ion sterilization device 30 is installed on the side through which the air flow of the internal air flow guide 43 flows.

Extend to the general air door, the electric ion sterilization device is best installed in the air outlet where the air flow is the largest. Due to the different designs of the cross flow fan blades, the air flow at each position of the air outlet is not necessarily the same. Generally speaking, the wind at the center of the cross-flow fan is the largest and most stable. Therefore, installing an ion sterilization device here can maximize the sterilization effect of the air in the surrounding environment. In addition, the number of ion sterilization devices 30 is not necessarily only two as in this embodiment (as shown in FIG. 1, one is provided at the center of each through-flow fan blade 12, because it is blocked by the intake guide plate 41 and cannot be seen directly. So the dashed line shows it). In other smaller air doors, there may be only one electric ion sterilization device; in other larger air doors, there may be more than two electric ion sterilization devices. According to the present invention, the number of electric ion sterilization devices installed is proportional to the average air output. For example, when the average air output is less than 1500CMH (Cubic Meter Peter Hour, cubic meters per hour), only one can be installed regardless of the number of cross-flow fans; when the average air output exceeds 1500CMH, an electric ion sterilization device is added. For example, when the average air output exceeds 1500CMH but less than or equal to 3000CMH, install 2 electric ion sterilization devices, when it exceeds 3000CMH but less than or equal to 4500CMH, install 3 electric ion sterilization devices, etc.

As mentioned above, the power module 20 includes a control circuit 21, and the function of the control circuit 21 is to control the electric ion sterilization device 30 and the fan module 10 to operate independently. When the fan module 10 is operating to generate an airflow wall, the control circuit 21 can be controlled (for example, remote control) to be turned on to perform air disinfection simultaneously; the control circuit 21 can also be controlled not to be turned on, thereby saving power. Of course, the control circuit 21 can be turned on intermittently according to a preset or artificial setting, so as to achieve a balance between the disinfection operation and the power consumption.

In the previous embodiment, the electric ion sterilization device is installed on the air duct, but this design may also affect the air output. In order to solve this problem, another embodiment of the present invention proposes a different design.

Please refer to Fig. 4, which is a front view of an air door 2 with an electric ion sterilization and deodorization device according to another embodiment of the present invention. The air door 2 with the electric ion sterilization and deodorization device uses many of the same components as the air door 1 with the electric ion sterilization and deodorization device in the previous embodiment. In order to reduce the complexity of the description, the same symbols in the two embodiments The components have the same function and type. The air door 2 with the electric ion sterilization and deodorization device can be installed above the inner side of an entrance and exit door, and activated to form an air flow wall inside the entrance and exit door. Similarly, the air door 2 with an electric ion sterilization and deodorization device also includes a fan module 10, a power module (not shown) that controls the operation of the fan module 10, at least one electric ion sterilization device 30 and the aforementioned A housing 40 for modules and devices. An air outlet 4 is formed under the casing 40. Different from the previous embodiment, the ion sterilization device 30 is not on the air duct but is located near the air outlet 42, for example, on the internal airflow guide plate 43, and a plurality of vents 44 are provided on the internal airflow guide plate 43. At least one electric ion sterilization device 30 is electrically connected to the power module and turned on to generate a plurality of electric ion groups in the surrounding air. When the outside air (shown by a hollow arrow) is sucked in by the air intake guide 41, it continues to rotate inside the housing 40, and finally flows out from the air outlet 42 under the housing 40 (the outflow air is drawn with a dot-shaped bottom arrow Show). These groups of electric ions are moved by the negative pressure of the aforementioned flowing air, pass through the vent 44, and are mixed into the air flow out of the air outlet 42 so as to achieve the purpose of wrapping and inactivating bacteria or viruses in the air flow out of the air outlet. Similarly, the group of electric ions can also oxidize the odorous chemical components in the airflow flowing out of the air outlet 42 to deodorize them.

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 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.
