Description

Condensation promoting cooking apparatus {ACCELERATING CONDENSATION TYPE COOKING APPARATUS}

The present invention relates to a condensation promoting cooking apparatus, and more particularly, to a condensation promoting cooking apparatus that can easily collect the liquefiable material in the gas.

Water is 70% of the human body, which is the second most needed after living for humans. Currently, there is a shortage of water around the world, and the price of drinking water is very expensive in countries where water is scarce.

 On the other hand, Korea is not short of the amount of water to be used per person, but due to the increase in population and changes in living environment, warning about water shortages is not ceaseless. In addition, since there is a tendency that water resources that can be used as drinking water are decreasing along with environmental pollution, interest in water resource development is increasing.

In addition to the water resources on the surface of the earth, such as rivers, and the water resources hidden inside the earth, such as groundwater, the resources to be considered are moisture contained in the atmosphere. About 15 g of water is contained in 1 kg of air having a dew point temperature (dew point temperature) of 20 ° C. at 1 atmosphere. If this air is cooled to 0 ° C, only 3.7g remains in the air and the remaining 11.3g is condensed into water. If air with a dew point temperature of 20 ° C is introduced at a wind speed of 5 m / s in a hose with a cross-section of 10 cm ² , the inflow rate is 0.005 m ³ / s. Therefore, the time required for the introduction of 1 m ³ of air is 200 sec (3.3 min), and since the air density is about 1.25 kg / m ³ , the weight is 1.25 kg. The amount of water extracted here is 11.3 x 1.25 (= 14.125 g). Thus, you can get 6.164 kg of water a day.

Thus, condensing moisture in the air to obtain water may be referred to as a new water resource, but using only a condenser using a separate cooler for this method has a problem in that it is inefficient in energy efficiency and lacks in economic efficiency.

The present invention has been invented to solve the above problems, it is an object of the present invention to provide a device for promoting the condensation of moisture in the air by using a cooler of the existing equipment installed without using a separate cooler.

In order to achieve the above object, the condensation promoting apparatus according to the present invention includes an inlet through which air is introduced into the through hole formed in the upper portion, an outlet through which air and liquid escape through the through hole formed in the lower portion, and a condensation tank having an empty inside. A condensing unit for condensing liquefiable materials such as water vapor contained in the air by cooling the air introduced into the condensing tank; An intake port connected to the outside at one end thereof and connected to the inlet at the other end thereof to intake an outside air containing the liquefiable material into the coagulation tank; A collecting part connected to the outlet and collecting the air and the condensed liquid in the condenser; And an exhaust portion connected to the outside at one end thereof and connected to the discharge hole, which is a through hole formed above the water collecting portion, to discharge the collected air of the liquid; It does not have a cooler of its own, the condensation unit is characterized in that installed inside the equipment having a cooler, such as a refrigerator to cool the internal air.

The air contains a considerable amount of water, and as the air temperature decreases, the amount of saturated water vapor in the air decreases. The temperature at which the amount of water vapor contained in the air is equal to the amount of saturated water vapor is called the dew point temperature (dew point temperature). When the air is cooled below the dew point temperature, water vapor condenses. Water can be obtained by condensing moisture in the air by using this principle, but in case of using a separate cooler to lower the temperature of the air, its efficiency is low and economical. Therefore, if a cooler such as a refrigerator generally used in homes, etc., without using a separate cooler, condensed water can be obtained without any economic burden.

The air also becomes denser and heavier as the temperature goes down. A relatively high temperature air rises up and a relatively low temperature air flows down. Therefore, the air cooled inside the cooling tank naturally flows out continuously through the lower outlet, and the outside air continuously flows through the intake unit to fill the voids. This circulation proceeds naturally without the need for a separate circulation device.

Further, in order to improve the cooling effect, a structure capable of detaching a plurality of cooling plates in the condensing tank is preferable, and the cooling plates may be made of a plate-like member having a plurality of holes formed by using a metal material having high thermal conductivity.

In addition, an air intake filter or a deodorant may be attached to the intake port, and an intake fan may be attached.

Furthermore, since the speed of the air flowing inside the condensation promoting device can be adjusted by adjusting the height of the exhaust port, it is preferable to have means for adjusting the height of the exhaust port.

Heating means such as a hot wire may be provided to prevent the condensed water from freezing to block the inlet and outlet of the condensation tank.

In addition, the condensation promoting cooking apparatus according to the present invention, the cooking apparatus for generating air containing the liquefiable material by heating, the air inside is discharged only to one place; It comprises an inlet through which air is introduced into the through-hole formed in the upper part, an outlet through which air and liquid escape through the through-hole formed in the lower part, and a condensation tank having an empty inside, and cooling the air introduced into the condensation tank into the air. A condensation unit for condensing the liquefied substance thus obtained; An air inlet is formed at one end of the air inlet of the cooking appliance, and the other end of the air inlet is connected to the inlet port to send air containing a liquefiable material into the coagulation tank; A collecting part connected to the outlet and collecting the air and the condensed liquid in the condenser; And an exhaust portion connected to the outside at one end thereof and connected to the discharge hole, which is a through hole formed above the water collecting portion, to discharge the collected air of the liquid; It does not have a cooler of its own, the condensation unit is characterized in that installed inside the equipment having a cooler, such as a refrigerator to cool the internal air.

According to the present invention, by using the cooler of the existing equipment installed and used without installing a separate cooler has the effect of extremely low production cost to obtain water by condensing moisture in the atmosphere. In addition, in the process of condensing moisture in the air, it is possible to obtain the effects of moisture removal, air purification, and deodorization.

In addition, when connected to cooking utensils, etc., there is an effect that can easily produce a distilled spirit, spices and the like at a low cost.

The present invention will now be described in detail with reference to the accompanying drawings.

1 is a view showing a condensation promoting device according to an embodiment of the present invention.

The condensation promoting device of the present invention includes an intake portion 10, a condensation portion 20, a collecting portion 30, and an exhaust portion 40. Among these, the condensation unit 20 is installed inside other equipment including a cooler, which will be described based on the case where it is installed in the refrigerator 100.

The intake unit 10 is a portion that serves to send air from the outside of the refrigerator 100 to the condensation unit 20 located inside the refrigerator 100, and at one end of the intake unit 10, an inlet opening ( 12 is formed and the opposite side is connected with the condensation part 20. To this end, a through hole penetrating the wall of the refrigerator 100 is formed, and an intake unit 10 is installed in the through hole. At this time, the efficiency of the refrigerator 100 is well sealed between the through hole and the intake portion.

The inlet 12 may be provided with a filter 14 for filtering foreign matter in the air. In this case, in addition to obtaining condensed water, the effect of purifying the indoor air can also be expected. And when the deodorant is provided in addition to the filter 14 described above, the effect of indoor deodorization can also be obtained.

In the condensation promoting device of the present invention, the inflow of the outside air is steadily made without additional equipment due to convection caused by cooling, but when the inflow of the outside air is difficult due to the need to adjust the air inflow amount or the above-described filter. An intake fan 16 can be mounted to the fan.

The condensation unit 20 is a portion that is installed inside the refrigerator 100 to cool the air introduced through the intake unit 10 to obtain condensation water, and a condensation tank for cooling the air and the inlet port 22 through which air enters ( 24) and an outlet 26 through which air and condensed water exit.

Inlet 22 is a portion in which the intake unit 10 is fastened so that air outside the refrigerator 100 is introduced. Since the air introduced from the outside is relatively warm air, in view of the convection phenomenon, the position of the inlet 22 is to be located above the condensation part 20.

The condensation tank 24 is an empty space in which the air introduced from the outside stays, and is located inside the refrigerator 100, and thus all of the wall surfaces are cooled. Therefore, the air located inside is also cooled, and moisture in the air condenses as the temperature of the air falls below the dew point temperature. The condensation tank 24 is manufactured in a shape that narrows toward the bottom in consideration of convection and discharge of condensation water. In addition, it is manufactured using a metal material with high thermal conductivity.

In the condensation tank 24, a cooling plate 50 may be installed to improve the cooling effect. Like the condensation tank 24, the cooling plate 50 is cooled due to the cold air of the refrigerator 100, so that the contact area between the air introduced into the condensation tank 24 and the cooled portion is widened, thereby speeding up the air. Cool. The cooling plate 50 is manufactured in the shape of a plate using a metal material having high thermal conductivity, and forms a through hole 52 therein to allow air to flow. 2 is a view showing one shape of a cooling plate. In addition, by increasing the number of the installed cooling plate 50, the contact surface increases and the flow of air is delayed by using the point that the cooling effect is improved, by controlling the number of the cooling plate 50 can adjust the cooling effect.

Since the condensed water obtained in the present invention may be used as drinking water, the condensed bath 24 and the cooling plate 50 use a material harmless to the human body. It is possible to coat the surface of copper with high thermal conductivity, or to use aluminum which is slightly lower in thermal conductivity but harmless to human body.

The outlet port 26 is a portion in which the condensed water obtained by cooling the air and the cooled air flow out of the condensation tank 24. In order to continuously obtain the condensed water, the outside air containing a lot of moisture must be continuously introduced, so the cooled air must be discharged to the outside, and when the condensed water stays in the condensation tank 24, it is inconvenient to take out the condensed water. Therefore, the outlet 26 is formed so that the condensation water formed inside the condensation tank 24 continuously flows outward.

The condensation unit 20 may be installed at both the refrigerating chamber and the freezing chamber of the refrigerator 100. If you need fast cooling, consider using a freezer. However, when the condensation part 20 is installed in the freezer compartment or when the condensation part 20 is installed in the refrigerating compartment, if the temperature of the refrigerating compartment is lowered a lot, the condensation water that prevents the condensation water frozen in the narrow inlet or outlet 26 is blocked. Problems may arise. In order to prevent this, heating means such as heating wires 28 may be installed at the inlet 22 and the outlet 26 to prevent melting or freezing of the ice. If ice is generated inside the condensation tank 24, the condensation unit 20 will be separated from the refrigerator to melt the ice inside.

The collecting part 30 is a part collecting the condensation water collected by the condensation tank 24. The water collecting unit 30 may be installed inside the refrigerator 100 or may be installed outside the refrigerator 100 so that the collected condensed water may be used at any time. However, it is better to install the condensation water to be installed below rather than the condensation part 20. The water collecting unit 30 is connected to the outlet 26 of the condensation tank 24 by using a hose 32 and the like, and when the water collecting unit 30 is installed outside the refrigerator 100, a through hole is formed in the refrigerator. And install a hose (32) or the like. At this time, the seal between the through hole and the hose 32 is well sealed so that the efficiency of the refrigerator 100 is not degraded.

The water collecting unit 30 also enters air cooled together with condensed water. In order to continuously introduce new external air into the condensation tank 24, the cooled air must be discharged, and a discharge port for this is formed above the water collecting part 30. Since the air just flowed out from the condensation tank 24 is lower than the temperature of the air previously introduced into the water collecting unit 30, the air is discharged as it is pushed down while being positioned downward.

The exhaust part 40 is a part which sends out the air which collected the condensed water. One end is engaged with the outlet 34 of the water collecting part 30, and the other end is formed with an outlet 42 through which air is finally discharged. A filter may be provided in order to prevent foreign substances such as dust from entering the exhaust port 42, or the exhaust port 42 may be bent downward by bending the end of the exhaust part 40. FIG.

When a separate intake means such as an intake fan is not operated in the intake port 12, the speed of the air flowing inside the condensation promoting device depends on the speed of the air discharged to the exhaust port 42. And the force that the air is discharged from the exhaust port 42 is a force that pushes up the air by the density difference according to the temperature of the air as described above. Therefore, the lower the height of the exhaust port 42, the easier the air is discharged, the faster the flow of air, on the contrary, the higher the height of the exhaust port 42, the slower the flow of the air. By using this advantage, the speed of the air flowing inside the condensation promoting device can be controlled by adjusting the height of the exhaust port 42. Means for adjusting the height of the exhaust port 42 may be provided in various ways, the simplest method is to configure the exhaust portion 40 to be hooked to the height-adjustable hook 44 as shown in FIG. have.

Referring to the operation of the condensation promoting device of the present invention configured as described above are as follows.

First, in consideration of the required degree of cooling, the condensation part 20 having the appropriate number of cooling plates 50 installed therein is placed in the refrigerating chamber or the freezing chamber of the refrigerator 100, and disposed at the inlet port 22 and the outlet port 26. One end of the base 40 is fastened to the hose 32 connected to the collecting part 30. However, before the condensation part 20 is installed, the through hole penetrating the wall of the refrigerator is blocked in order to prevent the efficiency of the refrigerator from falling.

While the condensation unit 20 is cooled by cold air inside the refrigerator 100, the condensation tank 24 and the cooling plate 50 are also cooled. As the temperature of the condensation tank 24 and the cooling plate 50 decreases, the temperature of the air in contact with these drops. When the temperature of the air decreases, water vapor contained in the air liquefies, condensing moisture, and cold air descends. At this time, since the condensation tank 24 becomes narrower toward the lower side, the condensed water also flows toward the outlet 26 and the cooled, heavy air flows out along the outlet 26.

When the cooled and heavy air flows out through the outlet 26, an empty space is formed inside the coagulation tank 24, and is connected to an inlet 22 formed above the coagulation tank 24 to fill this space. Air outside the refrigerator 100 is introduced into the condensation tank 24 through the intake unit 10. As the warm air of the refrigerator 100 introduced as described above is cooled, the above-described process is repeated.

On the other hand, the condensed water and the cooled air flowing out through the outlet 26 enters the water collecting unit 30 located outside the refrigerator 100. Condensed water is collected at the lower part of the collecting part 30, and cooled air is collected at the upper part. Condensed water and air enter into the catchment part because the discharge hole 34 penetrates the outside and is formed above the catchment part 30, and the air located above the exhaust part 40 is attached to the outlet port 34. It is then discharged to the outside.

At this time, since the air just leaked from the condensation tank 24 has a lower temperature than the air collected in the water collecting unit 30, the air collected in the water collecting unit 30 is located downward while pushing up the air collected inside the water collecting unit 30. Therefore, the higher the position of the exhaust port 42 through which the air is discharged to the outside, the more force is required to push the air up in the water collecting unit 30. This means that the air that is cooled in the condensation tank 24 must be stronger to enter the water collecting portion 30, and that the air stays in the condensing tank 24 longer and needs to be cooled more. As a result, as the height of the exhaust port 42 increases, the speed of the air flowing in the condensation promoting device decreases, so that the operating speed of the condensation promoting device can be adjusted by adjusting the height of the exhaust port 42.

The heat conductivity of the air is from ^{0 ℃ 2.4 x 10- 2 J m} -1 s -1 K -1, static vapor specific heat is 1463 JK ^-1 kg ^-1.

If the shape of the coagulation bath 24 is half of the cuboid of 50 x 20 x 20 (cm), the surface area is 0.3477 m ² (3,477 cm ² = [{(1/2) (50 x 20) x 2} + ( 20 x 20) + (20 x 50) + {(20 ² + 50 ² ) ^1/2 x 20}]). And the volume of this coagulation tank 24 is 0.02 m <^3> . If the temperature of the air sucked into the coagulation bath 24 is 25 ° C and the temperature in the coagulation bath 24 is -20 ° C, 0.375 J m / s per unit time (= 0.3477 m ² x 2.4 x 10 ^-2 J m ^-1). s ^-1 K ^-1 x (25-(-20)) K) flows. If the distance between the surface of the coagulation bath 24 and the air is set to 1 cm on average, it can be expressed as 37.5 J cm / s.

And so the average air density is 1.25 kg / m ^3, the air of 0.02m ³ is 0.025kg. To cool this wet air from 25 ° C to -20 ° C, 806.6 J (= 0.025 kg x 717 JK ^-1 kg ^-1 x 45K) must be exhausted. At this time, the static specific heat C _v of air was calculated as 717 JK ^-1 kg ^-1 . Therefore, it takes 21.6 seconds for the heat of air to be transferred through the iron plate at a distance of 1 cm. As a result, it is only 21.6 seconds in the cooler to be completely dehumidified and almost all of the water vapor in the air is converted to water.

However, even if the dew point temperature is 20 ℃ and the air temperature is 25 ℃, the mixing ratio decreases from 15 to 3.2 even if the air is cooled only to -2.5 ℃, and 79% of water vapor condenses, and the time to cool down to -2.5 ℃ is 10.8 seconds. to be. Therefore, cooling only to -2.5 ° C is efficient.

On the other hand, a method of reducing the cooling time of 10.8 seconds is to increase the cooling rate. In order to increase the cooling rate, the cooling plate 50 may be installed in the condensation tank 24 to increase the surface area in contact with the air. If the surface area of the added cooling plate 50 is the same as the internal surface area of the condensation bath 24, the total surface area is doubled and thus the cooling rate is doubled to 5.4 seconds. If the total surface area, which is the sum of the surface areas of the condensation tank 24 and the cooling plate 50, is ten times the surface area of the condensing tank 24, the cooling time is 1.08 seconds, and about 0.75 g per second (about 2700 g per hour). ) Water can be collected.

According to another use method of the present invention, the intake fan 16 may be installed in the intake port 12 through which outside air is introduced. In this case, the cooling process and the process of condensation water condensation are the same as above, but there is a difference that the air flow is forced by the intake fan 16. Therefore, the operating speed of the condensation promoting device cannot be adjusted to the height of the exhaust port 42, but must be adjusted through the intake fan 16. At this time, if the intake fan 16 is set too fast, the time for air to stay in the condensation tank 24 is shortened, and the condensed water may not be sufficiently obtained because it is not sufficiently cooled. However, in the case where the deodorant or the air purifying filter 14 is installed in the inlet 12, since the external air is hardly introduced into the condensing tank 24 only by the natural convection phenomenon described above, the efficiency of the intake fan 16 is improved. Will be increased.

Another embodiment of the present invention is to condense a specific material, not to condense moisture in the outside air. 4 is a diagram showing an embodiment of the present invention.

To this end, the inlet 12 is not opened to the outside atmosphere, and is fastened to the cooking appliance 60 where air is discharged. The material is put into the cooking utensil 60 and heated to create hot air containing a specific substance that can be liquefied, and the air forms the condensing bath 24 along the inlet 12 which is fastened to the discharge passage which is only one of the cooking utensils 60. Go to. As the air moved to the condensation tank 24 is cooled, a specific substance is liquefied and collected in the water collecting unit 30.

The specific substance is typically alcohol. When the steam produced by heating the alcohol-fermented food is passed through the condensation promoting device of the present invention, alcohol can be easily produced. In addition, by cooling the air generated by heating a strong fragrance material such as Schisandra chinensis can obtain a liquid living fragrance, which can be used as a fragrance as well as to develop a variety of applications by research.

In this case, it is not easy to control the degree of cooling because the speed of flowing through the condensation promoting device depends on the vapor pressure of the heating. However, unlike the case of collecting moisture in the air, since the case of liquefying steam is relatively effective because it does not require much cooling. For example, in the case of alcohol, since the vaporization temperature is 78 ℃ it will be easily liquefied inside the coagulation bath.

In the above, the present invention has been shown and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiments, and those skilled in the art to which the present invention pertains may variously change the present invention without departing from the technical spirit of the present invention. Therefore, the scope of the present invention should not be limited to the specific embodiments, but should be construed as defined by the appended claims.
