Description

Method for cleaning and reducing living space fine dust

The present invention relates to a method for cleaning fine dust and a method for reducing fine dust, and relates to a method for cleaning fine dust and a method for reducing fine dust to efficiently clean fine dust in a residential space.

In order to clean contaminated floors, suction-type vacuum cleaners used for floor cleaning at homes and businesses use negative pressure generated by intake means such as fanning dust and dirt from the floor, and inhale through the suction duct made of hood and tube together with air. And, after filtering the dirt using a network such as a nonwoven fabric, the inhaled air is exhausted to the atmosphere.

Conventional suction-type vacuum cleaners collect and remove dust and dirt with large particle diameters that are easily filtered from the respiratory tract, while dust and fine dust with small particle diameters that can penetrate deep into the respiratory tract are deposited in a relatively stable state on the floor. Since even dust scatters and floats into the indoor space, there is a problem that the cleaning act of removing dirt to restore a pleasant environment by increasing the chance of being inhaled by a person's respiratory system adversely affects the person's health.

Among the particulate matter contained in the air exhausted from the suction-type cleaning device, sedimentary dust having a large particle diameter and floating dust such as pollen can be cleaned by installing a general filter. However, it is difficult to purify fine dust such as mold and mite decomposition products and ultrafine dust such as cigarette smoke particles with a general filter.

If a filtration filter that can remove fine dust by sieving is installed in the cleaning device, the pressure loss increases as the particle size of the material to be removed increases, so the power and size of the intake fan and motor increase, and noise is generated. There is a drawback of frequent filter replacement in a short period of time. Therefore, if a filter for removing fine dust, a fan with a high suction power, and a motor are installed in the cleaning device, housewives with relatively weak strength due to weight and noise become difficult to handle.

1 is a diagram showing a solution for reducing fine dust in a residential space according to an embodiment of the present invention.

Dust refers to particulate matter that floats or scatters in the air. It is often generated when burning fossil fuels such as coal and petroleum, or from exhaust gases such as factories and automobiles.

Dust is classified into total dust (TSP, Total Suspended Particles), which is less than 50μm, and fine dust (PM, Particulate Matter), which has a very small particle size, depending on the size of the particles. Fine dust is further divided into fine dust (PM10) with a diameter of less than 10 μm and fine dust (PM2.5) with a diameter of less than 2.5 μm. If PM10 is about 1/5~1/7 smaller than the diameter of human hair (50~70μm), PM2.5 is very small, about 1/20~1/30 of the hair. Hereinafter, the term “fine dust” described in the present invention refers to dust having a diameter of less than 10 μm.

In order to reduce fine dust in the room, as shown in Fig. 1, i) install a window interceptor, ii) replace the window screen for ventilation with a fine dust net, iii) clean the indoor space using a water filter cleaner , iv) It can be achieved by regular management of the heat exchanger filter. It will be described in detail below.

1) Installation of complete circuit breaker between window gaps

It is possible to reduce indoor air pollution by blocking yellow dust and fine dust entering through the window as a source.

2) The window screen for ventilation is replaced with a fine dust screen.

Clean net installation filters fine dust and introduces fresh air with natural circulation function. It is composed of a light mesh and can be used for a long time without tearing or breaking, and rainwater does not enter the interior even when it rains. Indoor air pollution is usually 2 to 5 times higher than outdoors and 10 times more than outside air in winter. To solve this problem, ventilation must be provided. If the concentration of fine dust outside is high, the ventilation effect will not be seen.If a clean screen is installed instead of the insect screen at this time, it prevents the inflow of fine dust into the house without worrying about yellow dust, fine dust, and pollen even if the window is opened. It can be put into. Clean air is brought in, and natural ventilation keeps the indoor air quality.

3) Clean all indoor spaces using a water filter cleaner

It is a vacuum cleaner with air purifier, mite cleaner, and vacuum cleaning function. Unlike general vacuum cleaners, it features an air purification technology that uses water as a filter. Since water itself is used as a filter, there is no need to use a separate consumable filter, and it has the function of filtering 99.97% of fine dust as well as removing house dust mites and various germs, so it can be used as a vacuum cleaner as well as a bedding cleaner. . By using such a water filter cleaner, fine dust in a residential space can be reduced. A method of cleaning an indoor residential space for fine dust reduction will be described in detail with reference to FIGS. 2 to 4 to be described later.

When using a water filter cleaner, pure water can be used to remove dust and various harmful gases, germs, and odors floating in the air, and change the air to clean and fresh air. Therefore, the following functions can be performed.

-Air purification and odor removal function

-Remove harmful gas

-Indoor floor cleaning function

-Function to remove dust mites from blankets, beds, sofas, etc.

-Function to remove dust accumulated on home appliances and furniture

-Water suction cleaning function

-Dry, humidification, aroma function using oil

-Spray function

-Carpet cleaning

4) Regular management of heat exchanger filter

The ventilation device (total heat exchanger) discharges indoor air contaminated by fine dust, radon, etc., and introduces outdoor air into the room to remove fine dust. The built-in filter removes pollutants, introduces clean outdoor air into the room, and removes odors. In addition, it is possible to increase thermal efficiency during cooling and heating by minimizing heat loss in the air through a heat exchange element.

Indoor air pollutants such as fine dust and radon damage human health, intensify the waste of energy in the ventilation system (total heat exchanger), and also cause fire due to static electricity generated by accumulated dust, and infestation of pests and mold. , And it causes a variety of problems, such as smelling.

The lack of management of the ventilation system (total heat exchanger) installed to improve indoor air quality leads to unsatisfactory effects, waste of energy, and deterioration in health. Therefore, the ventilation system (total heat exchanger) maintenance solution can maximize the indoor air quality improvement effect. In addition to IAQ (indoor air quality), it can show a satisfaction level of 90% or more in various areas ranging from fire prevention, sanitation, and disaster prevention.

2 is a flow chart showing a method of cleaning fine dust in a residential space according to an embodiment of the present invention, and FIG. 3 is a flow diagram in which the water filter cleaner prioritizes the size of the residential space in the order of the largest size according to the embodiment of the present invention. This is an exemplary picture, and FIG. 4 is an exemplary picture of moving and cleaning by prioritizing in order of increasing carbon dioxide emission according to an embodiment of the present invention.

In the present invention, a water filter cleaner is provided with a filtering means inside the device to filter fine dust sucked into the device, and a cleaner that uses water as these filtering means, and uses water as the filtering means in the present specification. Is called a water filter cleaner.

The water filter cleaner includes, for example, a lower body having a water filter working space part forming a concave water filter working space, a hollow upper body installed on the upper end of the lower body, and a water filter. Water to communicate with the space separation unit installed in the working space, the accessory guide coupled to the bottom of the upper body, the rear filter and the accessory installed in the accessory guide, the suction pipe connected to the lower body to communicate with the water filter working space, and the suction pipe. It has a suction guide installed in the filter working space, a suction head coupled to the end of the suction pipe, and an exhaust motor and an exhaust fan installed inside the upper body.

Meanwhile, a water filter cleaner for cleaning fine dust in a residential space is a cleaning robot including a positioning module, a motor moving wheel, and a movement control module, and is a water filter cleaner that is moved by robot control. The movement control module can determine the current position of itself through the position identification module and drive a desired moving wheel to move it to a desired position. For reference, the location detection module can identify its location through a beacon sensor attached to each of the residential spaces, and in addition, it can identify its current location through various location detection means such as a triangulation method.

In the fine dust cleaning method and the fine dust reduction method in which the water filter cleaner cleans fine dust in a residential space, the water filter cleaner of the present invention moves to a residential space determined to need fine dust cleaning, and The fine dust in the residential space is removed by contacting water.

To this end, as shown in FIG. 2, the process of wirelessly transmitting the measured fine dust value to the water filter cleaner by the fine dust measuring sensor provided in each residential space (S10), and based on the measured fine dust value by the water filter cleaner. As a result, it is possible to carry out a process (S20) of moving to a residential space that is determined to require fine dust cleaning and cleaning by contacting water with fine dust in the moved residential space. Here, the residential space may correspond to a room, an entrance, a living room, a kitchen, and a veranda.

Also cleaned In the process (S20), the cleaning method of the corner may be different, that is, the corner may be Water filter The vacuum cleaner Can inhale Since there is no, it is possible to clean it by blowing out the fine dust and then discharging the fine dust to the outside and sucking the fine dust again.

Also fine dust When cleaning In the air It is possible to inhale fine dust due to the movement of fine dust or fine dust, but places that are not By hand variety Tools You can use it to remove fine dust.

Meanwhile, in determining that fine dust cleaning is necessary based on the measured fine dust value, a fine dust measuring sensor is used. The fine dust measurement sensor is provided in each residential space such as a room, entrance, living room, kitchen, and veranda, and measures fine dust in the corresponding residential space and transmits it wirelessly to a water filter cleaner. For reference, wireless transmission may use a wireless communication method such as infrared communication, Bluetooth, radio frequency (RF), and wireless LAN.

The residential space determined to need fine dust cleaning may be a residential space having fine dust exceeding a preset indoor standard value. For example, the measured value of fine dust in the bedroom is 20㎍/㎥, the measured value of fine dust in the living room is 35㎍/㎥, the measured value of fine dust in the entrance is 30㎍/㎥, and the measured value of fine dust in the kitchen is In the case of 50㎍/㎥ and the indoor standard value is 45㎍/㎥, the water filter cleaner moves to the kitchen exceeding the indoor standard value and cleans the fine dust in the kitchen.

In the above, the indoor reference value may vary depending on the amount of external fine dust measured. For example, the higher the external fine dust is measured, the lower the indoor reference value may be.This is because if the external fine dust is high, the surrounding fine dust is generally higher, although the internal fine dust inside the residential space is less than usual. Even if it is, it is necessary to clean fine dust more strictly.

In addition, the indoor standard value may vary depending on the occupants living in each residential space. For example, if the resident is a newborn baby, a child, or a person with respiratory disease, the higher the disease level of the newborn, child, or respiratory disease person, the lower the indoor standard value of the residential space can be set. Therefore, even if the same fine dust is measured in each residential space, if the indoor standard value of the living space in which newborns, young children, and people with respiratory diseases live are lower than the amount of fine dust measured, the living space in which newborns, small children, and people with respiratory diseases reside. Fine dust cleaning is performed using a water filter.

On the other hand, when there are two or more residential spaces that are measured as having fine dust exceeding the indoor standard value, cleaning standards are required because two residential spaces cannot be cleaned at the same time.

Therefore, if there are two or more residential spaces that are measured as having fine dust exceeding the indoor standard value, they are moved to the residential space determined by the preset cleaning standard and cleaned.

There can be two criteria for such cleaning criteria as follows.

The first cleaning criterion when there are two or more residential spaces is to move and clean the residential spaces in order of large size. For example, as shown in FIG. 3, if fine dust in the master room and living room exceeds the indoor standard value, first move to a large living room and then move to the next room after cleaning the living room. Let cleaning be done. Therefore, by cleaning the large space first, it is to preferentially block the spread of fine dust in the large space to other spaces.

Another second cleaning criterion when there are two or more residential spaces is to move and clean in the order of high carbon dioxide emissions. To this end, a carbon dioxide measuring sensor is provided in each residential space, and the measured amount of carbon dioxide in the residential space must be wirelessly transmitted to the water filter cleaner.

As shown in Fig. 4, when fine dust in the bedroom and living room in each residential space exceeds the indoor standard value and carbon dioxide emission is detected in the master room and not detected in the living room, first move to the master room where carbon dioxide is discharged, and then clean the bedroom. After completion, move to the living room for the next time so that the living room is cleaned. This is because humans emit carbon dioxide, so first of all, the living spaces where people are active are cleaned of fine dust.

The embodiments in the description of the present invention described above are presented by selecting the most preferable examples to aid the understanding of those skilled in the art from among various possible examples, and the technical idea of the present invention is not necessarily limited or limited only by this embodiment. , Various changes and modifications, and other equivalent embodiments are possible within the scope of the technical spirit of the present invention.
