Description

Multi-functional air purifier with module assembly structure and Internet on Things based indoor air quality management system}

The present invention relates to an air cleaning and ventilation device made of a modular type and to an indoor air quality management system using the same. More specifically, the air cleaning and ventilation device and the multiple air cleaners can be selected and manufactured according to the user's requirements. Indoor air quality management system using wireless communication-based IoT in operation.

Recently, the possibility of causing air pollution due to fine dust and ultrafine dust and various diseases such as respiratory organs, skin, and eyes is increasing. In order to prevent these problems, household air cleaners having various functions have been developed and sold. However, the current air cleaners are very difficult to use in low-income class because of their high price and easy management. Indeed, the most affected by air pollution are low-income people who are exposed to fine dust, which can increase personal and social costs. In order to solve these problems, low-income people can purchase and develop low-cost air cleaners faithful to the basic functions of air cleaners. In addition, the air environment is contaminated with various harmful substances such as indoor bacteria causing various infectious diseases, dusty volatile organic compounds causing sick house syndrome, and radon gas causing radiation exposure. Hazards caused by these various factors cannot be managed by a simple air cleaner equipped with only a fine dust sensor, but there is a demand for an air quality management system that can detect risk factors and inspect and manage air quality in various ways.

The present invention relates to a structure of a modular air cleaner and an indoor air quality management system using an IoT based multiple air cleaner. Modular prefabricated air cleaners can solve the problem of having to purchase expensive air cleaners, which are not needed due to the combination of existing air cleaners. It provides a structure for the user to select and purchase the function of. / Basic air cleaner can be used as a wall-mounted or floor-mounted type, and when combined with a fan module, it provides a function to simultaneously perform air cleaning and ventilation. In addition, if a module including fine dust, ultrafine dust, carbon dioxide, carbon monoxide, volatile organic compounds, and radon gas sensors is installed for air quality management, the air quality is managed by measuring various harmful substances. These various functions can be selectively applied according to the needs of the user, thereby eliminating unnecessary functions of the air cleaner and inexpensively purchasing and operating the air cleaner including only necessary functions. In addition, the air purifier's ability to purify air quality is usually limited to the room in which it is installed, so several air cleaners may be used. When operating several air cleaners in the house, the air cleaner provided by the present invention forms the Internet of Things network by wireless communication method to share air quality measurement data with each other, and secures data related to outdoor air quality through the Internet. Jointly, the operation for purifying indoor air quality is performed. The present invention can provide an efficient air quality management system by forming an Internet of Things network during the air cleaning period and jointly managing indoor air quality.

Modular prefabricated air cleaner of the present invention can perform a function to measure and manage the complex air quality by adding a low-cost air cleaner and a ventilation module and various sensor modules that perform the basic functions of air cleaning. In addition, it provides a system that jointly manages indoor air quality by sharing sensor measurement values for indoor air quality through the IoT network based on wireless communication using several modular assembly air cleaners. .

Module prefabricated air purifier can be included in the air purifier by selecting the necessary functions, so it is possible to use the air purifier at a low cost by eliminating the cost increase due to unnecessary functions, and upgrade the air purifier function by adding the necessary ventilation module and sensor module during use. It can provide a way to do it. Users can directly assemble and disassemble each module, so there is no need to repair the entire product when repairing due to a breakdown of the air cleaner, and it is possible to proceed with the repair of each module. In addition, when operating multiple modular air cleaners at the same time, it is connected by wireless communication method to share air quality measurement values measured by sensor modules of each air cleaner to detect changes in fine dust or various harmful substances, In response to co-operation, the air purification operation may be performed in advance, or ventilation may be simultaneously performed to respond to changes in air quality quickly.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and the contents described in the accompanying drawings, but the present invention is not limited or limited by the embodiments.

The air cleaner of Figure 1 is largely divided into an air cleaner module and a window-mounted ventilation module. The air purifier module consists of a two-way ventilation fan, an air filter, an air purifying / ventilating shutter, a prefilter, and a ventilation shutter. The two-way ventilation fan operates from inside to outside during ventilation, and from outside to inside during air purification. The air purifying-ventilating shutter blocks the connection path with the air filter during ventilation and allows only external air to flow into the ventilation fan, and at the same time, the ventilation shutter connected to the outside air is opened at the same time so that the air inside the ventilation fan, pre-filter and ventilation The camera may go out through the shutter or enter the outside air. When the air purifying-ventilation shutter opens the connection path with the air filter, the ventilation shutter is closed and the air inside is circulated through the ventilation fan through the air filter to purify the internal air. The space remaining when the window is mounted can be prevented from entering the fine dust by using a screen shade made to fit the window size. The air cleaner basic module is equipped with a control unit, a temperature and humidity sensor, and a fine dust sensor as a base as shown in FIG. 1, and additionally, a display module for displaying an air cleaner state, a carbon dioxide sensor module, a radon sensor module, a volatile organic compound sensor module, and a human body sensor. Modules and the like can be further mounted.

2 is a view showing a device type that can be utilized as a wall-mounted type in combination with an internal structure of a single air cleaner module and a wall-mounted cradle. A single air purifier module is composed of a ventilation fan, an air filter and a control unit. If a wall mount holder is added thereto, the air purifier can be used while being mounted on a wall as shown in FIG. 2 to increase space utilization.

Figure 3 shows a schematic diagram of the wireless communication connection when operating several air purifiers and porch sensor module at the same time. In general, since the air purifier can be cleaned up to a living room or room, the air purifier can be installed in a limited space in an individual home or office. That is, there are cases where several air cleaners are operated at the same time in individual households. In this case, each air cleaner has a problem that it is difficult to cooperatively cope with the air quality management of the entire house by operating individually. The air quality management system proposed in the present invention efficiently manages the air quality in the house because one of several air cleaners can perform ventilation or purification function in response to air pollution based on sensor values measured in each air cleaner. It has the advantage of being manageable. In addition, the porch module including a display and a sensor module that can be installed on the porch in addition to the air purifier is an additional module that detects a change in the air quality at the entrance and performs the air cleaning and ventilation function that is operating indoors. The entrance module includes a function that informs the weather of today's weather or fine dust forecast when going out from the entrance along with the pollution detection of the entrance.
