Abstract

The purpose of the present invention is to manufacture a humidifier for solving disadvantages, wherein each general humidifier definitely has advantages but also has disadvantages as much as the advantages. Moreover, additionally, the humidifiers are considered to be used in midwinter, so that the almost humidifiers are developed to increase peripheral temperature (inside of a room). By comparing and analyzing the humidifier based on temperature, humidity, cost, existence of hyper humidification, existence of condensation, noise, and a power consumption amount by setting the existing humidifier as a control group, the present invention seeks better features than the general humidifier when comparing a termite mound humidifier with the control group. The present invention concentrates on the disadvantages of each humidifier to analyze a result value in a way of supplementing the disadvantages.

Description

Termite house humidifier}

Architecture, chemical mechanics

In the field of architecture, the termite house principle is often applied.

Simply put, it is a structure that maintains the proper temperature and humidity by injecting the cold air below and discharging the hot air above.

In order to improve the disadvantages of these vaporization humidifiers-noise generation, low evaporation rate, and room temperature drop, we devised a "evaporative humidifier incorporating the white anthill principle".

Termites use the soil, excrement, and carcasses of their dead companions to build houses of about 6 meters with porous building materials. The white anthill built in this way maintains fresh air with a temperature of 27℃ and a humidity of 60% even in hot meadows exceeding 40 degrees Celsius. Its principle is the convection phenomenon.

The structure of the white anthill is largely divided into three types. Area A that discharges air from the upper part, area B in the middle that acts as a capillary tube for good air circulation, and area C that collects cold air. The activity of termites heats the internal air, and the heated air rises and escapes to the chimney (A) at the top because the density decreases. Accordingly, the air pressure in the lower part of the house (C) is lowered, so that cold air is introduced through the hole below to compensate for the difference in air pressure, and spread to the entire interior of the house through the capillary tube (B). In this process, as air is pushed toward the outer wall, carbon dioxide escapes and oxygen enters through the outer wall with many fine holes. This air warms up again and escapes through the hole in the top, causing continuous convection. Through this, the humidity and temperature of the air are adjusted to suit the internal environment.

If a porous material is used, the absorption and evaporation of the liquid will occur more easily. If the porosity is low, the drag force acts strongly and the droplets penetrate slowly due to the flow resistance into the medium. In addition, when the porosity is low, vapor generated near the droplet does not escape to the outside, and there is no change according to the velocity of the external flow. The higher the porosity, the more it is affected by external flow, and the flow can be easily affected by the empty space of the porous medium. That is, the higher the porosity, the faster the liquid absorption rate and the evaporation rate.

It was thought that the shortcomings of the existing vaporization humidifier could be supplemented by simulating such a white anthill. If water is evaporated by using the active convection phenomenon that occurs by heating the air inside the humidifier, and the evaporation rate of water is increased by using a porous filter like a porous termite house, the humidification efficiency can be improved. In addition, as the temperature increases, the amount of saturated water vapor increases, so if convection occurs with the heated air, a larger amount of moisture can be evaporated, and the humidification effect is expected to increase.

In the case of patent literature, we looked for patents using the termite nest principle, which is the most basic of this invention, and patents related to vaporization humidifiers.

Create a natural vaporizing humidifier and use the structure of a termite nest.

Dry indoor air in winter dries up the mucous membranes of the nose and bronchial tubes, reducing immunity, which is likely to cause respiratory diseases. It can also cause dry skin or dry eyes. Therefore, maintaining proper indoor humidity is important for disease prevention. Humidifiers are widely used because they can easily increase indoor humidity. However, they have several problems.

There are three types of humidifiers currently in use: ultrasonic humidifiers, heated humidifiers, and convection humidifiers.

Ultrasonic humidifiers use the vibration of ultrasonic waves to make water into small particles of tens of micrometers and spread it into the air. At the bottom of the ultrasonic humidifier, there is a'vibrating plate' to which a'ultrasonic vibrator' is attached. When current flows, the size of the vibrator changes and the diaphragm vibrates to generate ultrasonic waves. When the ultrasonic wave vibrates the water, water particles on the surface of the water bounce off the surface in the form of small particles, and these particles are released into the air through an internal fan. There is no risk of burns, power consumption is low, and noise is low. However, since the ultrasonic humidifier is vaporized indoors, the indoor temperature is lowered by the heat of vaporization. Because the water particles are large, overall humidification is not performed, and impurities contained in the water are also released, so bacteria in the water can enter the respiratory tract through the air. Therefore, it has to be cleaned frequently to prevent the growth of bacteria, but a ‘humidifier disinfectant incident’, which was added to the humidifier's water to prevent the growth of bacteria, caused the death of pregnant women, causing fear of consumers.

Heated humidifiers use electricity to boil water and spread water vapor into the air. Since water is boiled, it has a sterilization effect and the room temperature is maintained. However, since it generates a lot of heat, there is a risk of burns and power consumption is high.

Evaporative humidifiers complement the disadvantages of ultrasonic humidifiers and heated humidifiers. It uses natural wind or a fan to evaporate it naturally. Moisture particles are smaller than bacteria that grow in the tank, so impurities or bacteria in the water do not spread into the air and there is no risk of burns. Unlike the two types of humidifiers mentioned above, as the relative humidity increases, the amount of natural evaporation decreases, so even if it is operated for a long time, it does not become wet due to over-humidification. However, since the fan is running, it is noisy and it is difficult to increase the humidity in a short time due to the limitation of the evaporation rate. In addition, it has the disadvantage of lowering the temperature of the room due to vaporization of water.

Since the vaporization humidifier using the white anthill principle is a humidifier that complements the shortcomings of the existing ultrasonic humidifier, heating humidifier, and vaporization humidifier, the experiment was conducted by comparing their performance in the same environment. The criteria applied in the experiment are temperature change, humidity change, noise, price, power consumption, whether or not condensation of water droplets in the test box, and whether or not over-humidification is present.

1) Heated humidifier

A heated humidifier is a humidifier that uses electricity to raise the temperature of water to 100℃ and humidifies the surroundings with water vapor generated by boiling of water. By boiling water, sterilized humidification can be achieved, and at the same time, the ambient temperature is not lowered, so it has a heating effect in winter. However, since the water is boiled, all of the water evaporates in a short period of time, so the lasting power is weak and there is a risk of children's burns due to the hot outlet temperature. The main points of comparison with the humidifier are the presence or absence of condensation of water droplets, noise, and presence or absence of over-humidification.

2) Ultrasonic humidifier

An ultrasonic humidifier is a humidifier that uses electricity to generate ultrasonic waves, splits water into microns and spreads it into the air. Since this humidifier is a cold humidifier, it is safe for children and has the advantage of quick humidification. However, there is a risk of bacterial propagation because it spreads water droplets of larger particles than bacteria in the water, and there is a disadvantage that the indoor temperature is lowered in winter, and the water particles can sink to the floor as it is, making the floor a sea of water. The main points of comparison with the humidifier are temperature change and the presence or absence of over-humidification.

3) Natural vaporization humidifier

A natural vaporization humidifier is a humidifier that adds moisture to the atmosphere by evaporating it using natural wind or a fan on a filter moistened with water. Evaporative humidifiers have different amounts of evaporation depending on temperature and humidity, so they are not over-humidified, so they can maintain comfortable indoor humidity, and there is no worry about burns or spreading bacteria. However, if the room temperature is lowered due to evaporation heat and a fan is used, noise may be generated and sleep may be disturbed. The main points of comparison with our humidifier are noise, temperature change, and humidity change.

It is expected that a humidifier using the principle of a white anthill can be produced to provide high temperature and humid air in cold and dry winter, providing adequate humidity and temperature for human life. The operating principle of a general humidifier is very similar to that of an evaporative humidifier, but the cause of the convection phenomenon is different, and the change in efficiency accordingly is to be measured. It is expected that the consumption of power is also low because the amount of saturated water vapor increases due to temperature rise and natural convection is used. Measure the amount of moisture provided to a unit volume per unit time, to what extent the temperature of the unit volume can be increased, measure the time it takes to increase the temperature, and compare it with other humidifiers.

Humidity that gives comfort varies depending on the temperature. At 15℃, about 70%, at 18~20℃, 60%, at 21~23℃, 50%, and above 24℃ are 40%. Therefore, our group tried to aim for an optimal humidity of 60% at 18~20℃, which is the average indoor temperature in winter, but it is difficult to meet the experimental conditions of this temperature in the middle of summer, so we set a temperature between at least 19~22℃. I decided to measure the time and planned an experiment to measure the time to reach it.

A humidifier made using the white anthill principle can complement the weaknesses of existing humidifiers and create new value.

(1) It is safe to use.

Evaporative humidifiers evaporate the water absorbed by the filter, so the evaporating moisture particles are smaller than the bacteria that grow in the tank. Therefore, no humidifier disinfectant is required, and bacterial infection does not occur through the air. In addition, since heated humidifiers boil water and emit steam, the temperature at the outlet is high and there is a risk of burns, whereas a humidifier using the white anthill principle uses a lower temperature (50~60℃), so there is a risk of burns. none. Therefore, it is suitable for use by the elderly and pregnant women.

(2) No noise is generated.

An evaporative humidifier that uses an ultrasonic humidifier and a fan to generate forced convection generates noise because it operates the fan. Heated humidifiers generate noise while boiling water. On the other hand, a humidifier using the white anthill principle does not generate noise because it evaporates water using heat energy. Therefore, it is particularly suitable for use while studying, reading, and sleeping.

(3) It can be used as a portable humidifier due to its high energy efficiency.

Since the power consumption of a heated humidifier is as high as 120W, the portable humidifier on the market is an ultrasonic humidifier. However, the ultrasonic humidifier has a small space for humidification because the size of the water molecules sprayed is large and cannot be distributed far away. The power consumption of the white anthill humidifier is 12W, similar to that of an ultrasonic humidifier. Therefore, it can be used by connecting to an auxiliary battery, and it can be used for a long time with little power because it generates a humidification effect because spontaneous evaporation occurs even when the power is turned off. Therefore, it is suitable for portable use and can be expected to be used as a humidifier for vehicles.

(4) Good holding power.

Ultrasonic humidifiers and evaporative humidifiers artificially add moisture irrespective of the surrounding humidity to cause over-humidification and consume water quickly, which is not good for maintaining humidification, so it is not efficient for long-term maintenance. However, evaporative humidifiers do not cause over-humidification by changing the evaporation amount according to the humidity in the air. Therefore, it can supply moisture to the respiratory system for a long time, so it is good to put it on the bedside.

(5) It can also function as a heater and air purifier.

If a suitable heating device is used, it can act as a heater in winter by controlling the temperature of the internal heating device. In addition, since the principle of termite humidifier is to suck in outside air and discharge it again, it can function as an air purifier by replacing the filter from a humidifying filter to an air cleaning filter. Therefore, it is possible to make a multifunctional humidifier.

Figure 1 can be described in comparison with the termite nest principle. The blue arrow below indicates the inflow of cold air, and the hot air passes through the filter and exits the upper hole as the air is heated by a heating wire in the middle.
At this time, the heating wire can be compared to the generation of heat by termite metabolism in the termite nest, and the filter can be said to act as a capillary tube for the termite nest.

(1) Comparison of humidity arrival time

Tables 2-1, 2-2, and 2-4 show time on the x-axis and the amount of humidification on the y-axis. In the case of Table 2-1, the time for the natural vaporization method to reach 50% humidity in Table 2-2 is too long to properly view the remaining values, so the data obtained by removing the natural vaporization graph and comparing the data of the remaining humidifiers to be.

Table 2-3 shows the time required to reach the appropriate humidity 50 for each humidifier on the y-axis.

Through the graphs in Table 2-1, 2-2, and 2-3, the targets of our experiment are the natural vaporization humidifier using a hot wire, and the ultrasonic humidifier used as a control, a heating humidifier, and a natural vaporization using a fan. As can be seen from the graph above, the natural vaporization (FAN) takes the longest to reach 50% humidity, and the consumption time decreases in the order of ultrasound, vaporization (Heat), and heating.

In the case of Table2-4, data showing different performances according to the shape of the filter.

Heat' is the case when the filter is left around the heat source, and the data of the Heat is changed so that the air heated by the heat source passes through the filter unconditionally. Through this, the air heated by heat rises vertically, and the filter is tied up vertically. It can be seen that the case where air is also made to pass through the filter shows greater efficiency.

Table 3 is a graph showing only the time to reach 50% humidity for each humidifier. Through this, it can be seen that there is a disadvantage that the humidification efficiency is very inferior when a fan or a heating wire is not used compared to the advantages of the natural vaporization method.

The heating type humidifier takes 2 minutes to heat at the first operation, but in the table above, it is shown as the time consumed from the start of humidification immediately after heating ends.

It took 3600 seconds for a natural vaporizing humidifier, 221 seconds for an ultrasonic humidifier, 30 seconds for a heated humidifier, 155 seconds for a natural vaporizing humidifier using a hot wire, and natural vaporization using a fan. The type humidifier is 578 seconds. As for the humidification rate, the heated humidifier reached the humidity 50 the fastest in the order of the natural vaporization method using a fan, the ultrasonic method, the natural vaporization method using a hot wire, and the heating method. The natural vaporization humidifier using a hot wire, which is our experiment, reached the second fastest, about 23 times faster than the natural vaporization humidifier and about 4 times faster than the natural vaporization humidifier using a fan. This shows that among the same natural vaporization humidifiers, the method using a hot wire shows the highest humidification efficiency.

(2) Comparison of over-humidification

Table4 shows the humidity according to the operating time on the y-axis.

The appropriate indoor humidity in winter is 40-60%, and there is a risk of mold growth if excessive humidification (over-humidity) occurs. While there is little concern about over-humidification in the naturally vaporized humidifier, the forced humidification method such as the ultrasonic and heating humidifiers continued to humidify even when the humidity exceeded 60%. In the experiment, the natural vaporization humidifier was measured until the humidity was no longer easily increased, and the result showed convergence around 50% of humidity. At this time, the natural vaporization humidifier using a hot wire reached 50% of the proper humidity faster than the natural vaporization humidifier using a fan.

(3) Comparison of power consumption

Table 5 shows the power consumed to reach the proper humidity 50 by comparing each humidifier.

The natural vaporization humidifier using a fan consumed 1445J, the natural vaporization humidifier using a hot wire 1860J, the heating humidifier 12250J, and the ultrasonic humidifier 3783J. The goal of our experiment was 1860J, which consumed 415J more than a humidifier using a fan, but showed a consumption efficiency that was about 7 times higher than that of a heated humidifier and about 2 times that of an ultrasonic humidifier.

(3) noise comparison

Table 6 is a graph showing the MAX and MIN values of each humidifier noise. At this time, the loudest noise in the MAX value is an ultrasonic humidifier, and the smallest one is a humidifier using a heat source. In addition, ultrasonic humidifier is the one with the loudest noise in MIN value, and the humidifier using a heat source that makes the smallest noise is. In the case of a humidifier using a heat source, it means that there is almost no sound, and in the case of more than 60 decibels, it is the sound of a noisy bar.
