Description

Direct injection vaporization device

The present invention relates to a direct injection type vaporization apparatus, and more particularly, by providing a warm air and blowing the liquid containing the vaporized instantaneously in the warm air, so as to effectively reach all corners through which air flows to maximize energy efficiency It relates to a spray vaporization device.

With the development of eco-friendly insecticides and the film industry, various kinds of perfumes prepared in advance according to the plot of the film are sprayed according to the plot of the film for a sense of reality.

However, the vaporization apparatus according to the prior art has the following problems.

First, because the spray particles of the liquid to be sprayed in the air is too large, due to the load of the liquid is not easily sprayed to the bottom of the area to be sprayed due to the load of the liquid has dropped the effective side.

For example, in the case of a humidifier which is one of the vaporizers, the humidification effect was not maximized, and when used with a warm air device, it was not very effective in increasing the room temperature.

That is, when a warm air device and a humidifier are used together indoors in winter, the steam of the humidifier contained in the warm air dissipates energy as much as the heat obtained when it is vaporized to increase the room temperature rise, due to the load of the steam as described above. It did not reach the corner of the room, the energy efficiency was not maximized.

In other words, the temperature is high around the hot air heater and the humidifier, but the temperature difference is so great that the rest of the area is not efficient.

Second, if the vaporization device is provided for spraying warm air and medicinal herbs for cultivation of crops, etc., the effect is increased when the medicinal components are evenly dispersed in the air, but the liquid drops directly on the leaves of the fruit due to the liquid load. There was a problem that it is difficult to increase the quality of the product because it caused the wound on the leaves.

Third, in order to solve the above problems, in order to minimize the particles in the liquid state, a heating method of directly injecting the gas directly into the heating element is required, but in this case, the temperature of the heating element may be quenched and precipitates may be generated. Since it comes in direct contact, problems such as high maintenance costs due to problems such as corrosion occurred.

The present invention has been made to solve the above problems, the object of the present invention is to minimize the particles of the liquid to be sprayed to the outside to be evenly distributed to the area to be sprayed, even if the liquid directly touches the temperature is not quenched constant It is to provide a direct injection vaporization apparatus using a molybdenum heating element to keep it so as to prevent corrosion of the molybdenum heating element.

To this end, a case including a suction unit and a discharge unit; a water tank installed in the inner lower portion of the case; a blower duct installed in the inner upper portion of the case, the pipe duct is formed toward the discharge portion; is installed in the blower duct, the air through the discharge portion Blowing fan for discharging to the outside; The blower duct and the water tank is connected to each other, the pressure duct is installed in the opening of the blower duct side guide portion for guiding a part of the discharge pressure of the blower fan into the water tank; It provides a direct injection type instantaneous vaporization apparatus comprising a plurality of heating elements: installed between the blower duct and the discharge portion to vaporize the water discharged by the blower fan.

In this case, it is preferable that a nozzle for spraying water pumped by the pressure pump is installed in the blowing duct, and a steel mesh is further installed in the blowing duct between the nozzle and the heating element.

At this time, it is preferable that an auxiliary heating element is further installed between the nozzle and the pressure pump.

In addition, it is preferable that a sub flow passage connecting each other is formed between the portion just before the heating element and the pressure flow passage in the blowing duct.

(I) consisting of a tube and a heat dissipation fin, wherein the heat dissipation fin and the copper tube is preferably plated with gold.

According to the direct injection vaporization apparatus according to the present invention has the following effects.

First, since the solution and the air to be injected are instantaneously vaporized by direct thermal contact with the heating element, the energy consumption efficiency is improved, and the discharged warm air has a performance of rapidly spreading everywhere where air flows due to an increase in enthalpy by vaporization heat.

Accordingly, in the case of the vaporization device that the humidification and warm air action at the same time, the heat efficiency is high to minimize the energy consumption for heating, and in the case of drug spraying the drug can be evenly spread throughout the plastic house, This is effective to increase.

Second, by using a heating element having a molybdenum heating wire, even if the liquid directly contacts the heating element, the heating element is not quenched or precipitates are generated, there is an effect corresponding to the characteristics for the instantaneous vaporization.

Third, the molybdenum heating element is inevitably in continuous contact with the liquid phase due to the nature of vaporizing the liquid phase to the molybdenum heating element at the moment, the gold plating and copper material for the corrosion prevention is used to solve the problems, the lifetime of the heating element And it is effective to increase the efficiency of the vaporizer.

At this time, the high water level sensor 211, when the solution is introduced into the water reservoir 200, when the water level approaches or reaches the high water level, a warning sound is generated to stop the user from entering the solution.

On the contrary, the water shortage sensor 212 serves to stop the operation of the pressure pump 600 to be described later by detecting the low water level of the solution.

On the other hand, the solution flowing into the reservoir 200 is a mineral component, phytoncide solution, herbal extracts, mugwort extract, which may be beneficial to the human body when contained in the indoor air, as well as various insecticides required for agricultural cultivation Can be.

Next, the air blowing duct 300 is a conduit through which the air introduced into the case 100 and the solution of the reservoir 200 are discharged toward the heating element 700, and is installed on the inner upper portion of the case 100.

In this case, a space for installing the blowing fan 400 is formed at the rear end of the blowing duct 300, and the front end corresponds to the heating element 700 to be described later.

At this time, an opening for forming the pressure passage 500 to be described later is formed on the bottom surface of the blowing duct 300.

In addition, a nozzle 310 is installed on an upper surface of the air blowing duct 300, and a pumping pipe 320 is formed between the nozzle 310 and the water reservoir 200.

By such a configuration, the solution of the reservoir 200 may be injected into the blowing duct 300 through the nozzle 310 along the pumping pipe 320.

At this time, it is preferable that the steel mesh 330 is further installed between the nozzle 310 and the tip of the inside of the blowing duct 300.

The steel mesh 330 serves to crush the liquid phase before the liquid phase discharged by the blowing fan 400 reaches the heating element 700.

At this time, the steel mesh 330 has a function to allow a plurality of through-holes are formed in a thin thin plate, so that the air and the liquid discharged by swelling the liquid finely mixed with each other.

Next, the blowing fan 400 flows in the outside air through the suction unit 110 and discharges it through the discharge unit 120, and serves to pump the liquid phase injected into the blower duct 300 to the heating element 700. .

At this time, the blowing fan 400 is preferably a sirocco fan.

Next, the pressure passage 500 serves to smoothly pump the solution of the reservoir 200 using the pressure of the blower fan 400.

That is, the atmospheric pressure in the blowing duct 300 is formed by the blowing fan 400 to be high, thereby guiding a part of the pressure to the reservoir 200 to pressurize the water surface of the reservoir 200.

Such a configuration uses Pascal's principle.

At this time, the pressure passage 500 is formed by connecting the opening formed in the bottom surface of the blowing duct 300 and the opening formed in the upper portion of the reservoir 200.

At this time, it is preferable that the guide piece 510 is further formed in the opening formed in the blowing duct 300 of the pressure flow path 500.

The guide piece 510 serves to maximize efficiency in guiding the high pressure in the blower duct 300 to the reservoir 200.

That is, as shown in FIG. 1, a portion of the liquid phase that is not in contact with the heating element 700 during the liquid phase being pushed through the steel mesh 330 is naturally dropped into the water storage tank 200 through the sub-channel 520. It is.

Next, the pressure pump 600 serves to pump water in the reservoir 200 into the air blowing duct 300, and is installed in the pumping pipe 320.

The pressure pump 600 is preferably a metering pump (chemical pump).

The metering pump discharges only a certain flow rate, and has the feature of adjusting and confirming the total flow rate consumed with the metering control.

On the other hand, by applying the pressure of the blower fan 400 to the reservoir 200 according to the principle of Pascal, the pumping burden for the pressure pump 600 can be alleviated somewhat.

On the other hand, the auxiliary heating element 610 is preferably installed between the pressure pump 600 and the nozzle 310.

This is to increase the temperature by first heating the liquid phase with the water temperature of room temperature before the injection through the nozzle 310, so that the effect of vaporizing through the heating element 700 can be maximized.

Next, the heating element 700 converts the air blown through the blower duct 300 into warm air, and the liquid phase pumped through the steel mesh 330 serves to vaporize.

That is, the air blown by the blower fan 400 is converted into warm air while passing through the heating element 700 and discharged to the outside of the case 100, and the compressed liquid is thermally contacted with the heating element 700 to be vaporized and vaporized. Vaporized heat is also discharged to the outside of the case 100 together with the warm air.

At this time, the heating element 700 is provided as a molybdenum heating element.

Due to the characteristics of the vaporization device according to the present invention, the heating element 700 should be directly sprayed with liquid phase so that the temperature of the heating element 700 is lowered or corrosion and deposits are not generated.

In order to satisfy this, the heating element 700 is provided as a molybdenum heating element in which molybdenum heating wire is installed.

The molybdenum heating element is a high temperature heating element having a heat generation temperature of 1900 degrees, and has a longer life, a faster heat generation rate, and a constant temperature characteristic in which the resistance value varies depending on the temperature, such as ceramic PTC, as compared to a sheath heater having a nickel-chromium heating wire. There is this.

In addition, the durability is strong, there is an advantage that does not oxidize or degrade performance.

Due to this characteristic, even if a liquid with a relatively low temperature is directly sprayed on the heating element 700, it is possible to maintain a constant discharge wind temperature by adjusting the thermal energy absorbed as the liquid jetting liquid is vaporized by the constant temperature characteristic.

On the other hand, the vaporization device having a characteristic that the liquid phase is directly sprayed on the heating element 700, it is very important that the corrosion of the heating element 700 does not occur.

The heating element will be described in more detail with reference to FIGS. 3A and 3B.

3A illustrates one heat generating unit constituting the heat generating element, and FIG. 3B is a view illustrating a front cross section of the heat generating unit.

3A and 3B, the heating element 700 includes molybdenum heating wire 710, magnesium oxide 720, SUS pipe 730, copper pipe 740, and heat radiation fin 750. It is composed.

Since the molybdenum heating wire 710 exhibits a phenomenon in which electrical resistance is increased or decreased due to the constant temperature holding property of molybdenum, even when direct injection instantaneous vaporization is a technical feature of the present invention, it is possible to maintain a uniform discharge wind temperature.

In addition, the magnesium oxide 720 serves to insulate the current flowing through the molybdenum heating wire 710 from leaking to the outside, and is installed to surround the molybdenum heating wire 710.

In addition, the SUS pipe 730 serves to prevent excessive heat of the molybdenum heating wire 710 up to 1900 degrees to prevent heat from flowing out.

Accordingly, the surface temperature of the heating element directly contacted by the pressurized liquid phase may be maintained at about 200 degrees without evaporating at all times.

And, the copper pipe 740 is to prevent corrosion, is installed in close contact with the SUS pipe 730.

The copper pipe 740 is made of a copper material having a very good thermal conductivity so that the heat energy passing through the SUS pipe 730 can be smoothly absorbed to achieve an optimal heat exchange between the liquid phase and the introduced indoor air.

Accordingly, by quickly absorbing the surface heat of the SUS pipe 730, it is possible to quickly replenish the surface temperature dropped due to the contact of the liquid phase.

In this case, the copper tube 740 is preferably plated with gold, which is an excellent material for preventing corrosion, to prevent corrosion.

In addition, the heat dissipation fin 750 serves to enlarge the area in which the inlet air and the liquid phase are in thermal contact, and the material is provided with a copper material having high thermal conductivity.

At this time, the heat dissipation fin 750 is preferably made of a gold plating treatment to prevent corrosion.

On the other hand, it is preferable that a plurality of the heating element described so far is installed from the front end portion of the blower duct 300 to the discharge portion 120, in the present specification, two heating elements 700 are installed for the purpose of understanding.

At this time, for convenience of description, the heating element 700 installed at the front end of the blower duct 300 is referred to as the first heating element 700A, and the heating element 700 proximate to the discharge part 120 is referred to as the second heating element 700B.

The first heating element 700A is a portion in which the liquid and the air pushed through the steel mesh 330 are first vaporized, and the second heating element 700B completely vaporizes the liquid that has not been vaporized during the vaporization process. Site.

On the other hand, it is preferable that the vaporizer 800 is further installed between the first heating element 700A and the second heating element 700B.

The vaporizer 800 forms a chamber 810 partitioned into a plurality of partitions, and serves to guide the liquid and hot air passing through the first heating element 700A to be uniformly discharged without being biased to either side. .

That is, since the liquid and hot air passing through the first heating element 700A uniformly pass through each chamber 810 of the vaporizer 800, the warm air and the vaporized heat passing through the second heating element 700B and the discharge port 120 are It can be discharged uniformly.

Hereinafter, the operation of the vaporization device having the above configuration will be described.

When the power switch 156 is operated to apply power to the vaporizer, various sensors of the control panel 150 operate, and the heating of the heating element 700 is operated together with the rotation of the blower fan 400.

Thereafter, the pressure of the pressure pump 600 and the pressure by the blower fan 400 acts into the water tank 200 along the pressure passage 500 by the guide piece 510 and the liquid phase through the nozzle 310. It is injected into the blowing duct 300.

Such a principle can be smoothly pumped by the principle of Pascal as described above.

Meanwhile, the pumped liquid is pumped along the pumping pipe 320 and then injected into the blowing duct 300 through the nozzle 310.

At this time, the liquid phase is a state heated by the auxiliary heating element 610, a water temperature higher than the temperature of the room temperature is formed.

Thereafter, the liquid phase injected into the blowing duct 300 is forwarded by the blowing fan 400 along the blowing duct 300.

In this case, the liquid is vaporized after contacting the first heating element 700A in a state of being broken into fine pieces while passing through the steel mesh 330, and the air blown by the blowing fan 400 also passes through the first heating element 700A. The temperature rises.

At this time, in the process in which the liquid phase is passed through the steel mesh 330 to the first heating element 700A, the liquid phase that is not in contact with the first heating element 700A and is dropped downward along the sub-flow path 520. As it is re-introduced into, there is a feature that can be recycled.

Meanwhile, the vaporized heat passes through the vaporizer 800 together with the warm air whose temperature rises through the first heating element 700A.

At this time, the warm air and the vaporized heat passes through the respective chambers 810 of the vaporizer 800, and thus is in contact with the second heating element 700B evenly distributed.

In this case, since the vaporizer 800 is also disposed between the heating elements 700 and made of the same material, the vaporizer 800 has a high thermal conductivity and a high surface temperature.

That is, it can also serve to vaporize the liquid phase that is not vaporized in the first heating element (700A).

Thereafter, the warm air and the vaporized heat passing through the vaporizer 800 are finally passed through the second heating element 700B and discharged to the outside.

As such, the reason why the liquid is crushed several times and passed through the heating element 700 is to prevent the liquid phase from being discharged into the liquid form without evaporating the outside of the vaporization apparatus.

That is, since the pressure of the blower fan 400 increases, the liquid may be immediately discharged to the outside, such that a burn or the like may occur.

As described above, the vaporization apparatus according to the present invention has a feature that the liquid phase is directly sprayed onto the heating element 700 and discharged in a vaporized state, so that it can be evenly sprayed throughout the room.

Accordingly, when used as a warm air device, there is a technical feature that the room temperature increase effect relative to the energy in addition to the humidification effect.

In addition, when used as a spreading device for crop cultivation has a high technical characteristics of sterilization disinfection by spraying mixed with air evenly throughout the plastic house.
