Description

Humidifier {Humidifier}

The present invention relates to a humidifier.

Humidity, in a broad sense, is the ratio of water contained in all materials and plays an important role in our living environment as much as temperature, and the inclusion of moisture in the atmosphere is a very important factor in human and animal environments. In particular, not only in everyday life, but also in life on the earth, the existence of air with proper humidity can maintain life, and human comfort life is affected by temperature and humidity control. Humidity is also a very important factor because the quality and performance of various products vary depending on the amount of humidity in various industrial fields. Generally, the indoor air maintains a proper humidity of about 60%, thereby preventing respiratory disorder or disease, and maintaining a pleasant indoor atmosphere. If there is no adequate water vapor in the room and the temperature rises, it becomes dry. In this way, the humidity of the room can be adjusted by using a humidifier when it is dried.

Examples of the type of the humidifier include a centrifugal atomizing type humidifier for granulating the inhaled water by centrifugal force and an electric humidifier for generating steam by heating the water with a heater or an electrode. In addition, there are a vaporization type humidifier which evaporates water by passing air through a wet filter, and an ultrasonic humidifier which generates ultrasonic waves by transmitting a high frequency electric signal generated by a driving circuit to a vibrator.

Of the various humidifiers, the ultrasonic humidifier has an abundant amount of humidification, and there is no fear of burning. However, the ultrasonic humidifier according to the related art has a problem of spraying fine particles contaminated with bacteria, bacteria, mold or the like. Specifically, as disclosed in the patent documents of the following prior art documents, the tuyeres communicating with the air blowing fan and the anemometer are arranged on different axes. Due to such a configuration, fresh air supplied to the blowing fan is not directly discharged to the atomizer, but air in the water bath is pushed by the air supplied to the blowing fan and discharged. Here, the air in the water tank is highly likely to be contaminated by stored water. Therefore, there is a problem that the ultrasonic humidifier according to the related art has a high possibility of jetting contaminated fine particles. In addition, since the air supplied to the blowing fan necessarily contacts the surface of the stored water over a certain distance, and then is discharged to the atomizer, there is a problem that the air can be discharged in a contaminated state by the stored water.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of related arts which may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of a humidifier according to an embodiment of the present invention.

1, the humidifier according to the present embodiment includes a water tub 110, a blowing pipe 120 communicating with the water tub 110 to supply air to the water tub 110, And a discharge pipe 130 facing the blowing pipe 120 so as to correspond to a direction in which air is blown by the blowing pipe 120. The blowing pipe 120 includes a main body 123, (125) having a smaller cross-sectional area than the main body (123).

For example, the water tub 110 is connected to the lower end of the water tub 120 so as to communicate with the lower end of the water tub 110, and the drain pipe 130 is connected to the upper end of the water tub 110 to communicate with the upper end. The air supplied from the blowing pipe 120 is discharged through the discharge pipe 130 and the mist is discharged through the discharge pipe 130 together with the air between the blowing pipe 120 and the discharge pipe 130. At this time, the mist is generated from the water stored in the water tank 110. An ultrasonic vibrator 113 is provided on one side (lower side) of the water tub 110 to generate mist from the water. Specifically, the ultrasonic vibrator 113 is formed of a piezoelectric ceramics or the like and generates ultrasonic waves, thereby generating cavitation, which is a phenomenon in which small bubbles of vacuum are produced by the vibration effect. Due to such cavitation, fine water vapor may protrude from the surface of the water to generate mist. In addition, when mist is generated from the water stored in the water tub 110, the water level of water stored in the water bath 110 is lowered, so that it is necessary to supply water to the water bath 110. Accordingly, the water level sensor 150 is provided in the water tank 110 to sense the water level. If the water level is below the predetermined level, the water storage tank 155 is stored in the water tank 110 through the supply line 157 Additional water can be supplied. Meanwhile, a ceramic ball (115) may be provided inside the water tank (110). Here, the ceramic ball 115 sterilizes the water stored in the water tub 110 to prevent water stored in the water tub 110 from being contaminated.

The blowing pipe 120 serves to supply air to the water tub 110 and communicates with the water tub 110. The blowing tube 120 includes a main body 123 and an extension 125 extending from the main body 123 toward the discharge tube 130 and having a smaller cross sectional area than the main body 123. [ That is, the blowing tube 120 is extended in a constant cross-sectional area, and the sectional area is narrowed at the end. The air supplied through the blowing pipe 120 becomes narrower in cross section at the extension portion 125, so that the speed increases. As a result, the final air velocity supplied to the water tub 110 from the blowing pipe 120 is very fast, and thus the pressure is low. The mist generated from water in the water tub 110 is moved between the blowing pipe 120 and the discharge pipe 130 and finally discharged to the discharge pipe 130 together with the air . At this time, the air is supplied to the water tub 110 from the air blowing pipe 120 and is discharged to the discharge pipe 130 together with the mist, so that the fine particles contaminated by the air in the water tub 110 or the stored water are prevented from being discharged The details of this will be described later. In this case, in order to prevent the water stored in the water tub 110 from flowing into the blowing pipe 120, the blowing pipe 120 is connected to the lower end of the water tub 110, And extends to a position higher than the water level. In order to supply air to the water tub 110, the blowing pipe 120 may be provided with one or more fans 127, and the fan 127 blows air toward the water tub 110 . At this time, the air blown into the fan 127 is supplied to the water tub 110 through the blowing pipe 120, and the air supplied to the water tub 110 is discharged through the discharge pipe 130 facing away from the blowing pipe 120 do. In addition, an air filter 129 may be connected to the blower pipe 120 to purify the air. Here, the air filter 129 may be, for example, a HEPA filter capable of removing viruses, fungi, mites and the like. Specifically, the HEPA filter is a collection of irregularly arranged fibers in which the particles in the air are blocked by the fibers and are caught on the fibers by electrostatic forces. However, the air filter 129 does not necessarily have to be a HEPA filter but may be any type of air filter known in the art.

The discharge pipe 130 serves to discharge air and is in communication with the water tub 110. For example, when the blowing pipe 120 is communicated with the lower end of the water tub 110, the discharge pipe 130 is communicated with the upper end of the water tub 110. Here, the discharge pipe 130 faces the blowing pipe 120 so as to correspond to the direction in which the blowing pipe 120 injects air. That is, the discharge pipe 130 is disposed on the same axis as the blowing pipe 120. Therefore, the air supplied from the blowing pipe 120 can be discharged directly to the discharge pipe 130 (see the enlarged view of FIG. 1). The air in the water tub 110 which is likely to be contaminated is not pushed by the air supplied from the air blowing pipe 120 and discharged to the discharge pipe 130 but the air supplied from the air blowing pipe 120 directly flows into the discharge pipe 130 . Here, since the air supplied from the air blowing pipe 120 is purified by the air filter 129, the humidifier does not finally spray the contaminated fine particles. Besides. The air supplied from the air blowing pipe 120 is discharged to the discharge pipe 130 without contacting the surface of the water stored in the water tub 110. Therefore, it is possible to prevent the possibility that the air is contaminated by the water stored in the water tub 110 in advance.

Since the discharge pipe 130 is spaced apart from the blowing pipe 120 by a predetermined distance, the mist generated from the water can be moved between the discharge pipe 130 and the blowing pipe 120 and discharged to the discharge pipe 130 together with the air. In order to smoothly discharge the air supplied from the blowing pipe 120 through the discharge pipe 130, the extension part 125 of the blowing pipe 120 is formed to have a cross-sectional area smaller than that of the end of the discharge pipe 130, (See the enlarged view of Fig. 1). That is, since the distal end of the discharge pipe 130 having a relatively large cross-sectional area is opposed to the extended portion 125 of the blowing pipe 120 having a relatively small cross-sectional area, air is smoothly transferred from the blowing pipe 120 to the discharge pipe 130 .

On the other hand, when the blowing pipe 120 and the discharge pipe 130 are separated from each other, the air supplied from the blowing pipe 120 may not be discharged directly to the discharge pipe 130, The mist may not be discharged to the discharge pipe 130 together with the air. Therefore, the distance between the blowing pipe 120 and the discharge pipe 130 is preferably 0.5 to 1 times the diameter of the end of the discharge pipe 130, but the present invention is not limited thereto.

Also, the discharge pipe 130 may be rotatable with respect to the water tub 110 so that the humidifier can adjust the direction in which the mist is sprayed. Meanwhile, in order to prevent contamination of water and air stored in the water tub 110, the discharge pipe 130 may be provided with an opening / closing part 133. The opening and closing part 133 may include a switch 133b for driving the switch 133a and the switch 133a. Specifically, when the blowing pipe 120 supplies air, the driving unit 133b opens the opening and closing unit 133a to open the discharge pipe 130 so that the discharge pipe 130 can discharge the air. On the other hand, when the air blowing pipe 120 does not supply air, the driving unit 133b closes the opening / closing unit 133a to close the discharge pipe 130, so that the pollutants of the outside are introduced into the water tub 110 through the discharge pipe 130 Can be prevented.

In addition, the discharge pipe 130 may be connected to the discharge pipe 140 and the air supply pipe 145. Here, the injection tube 140 is in communication with the discharge tube 130, and extends at a predetermined angle with the discharge tube 130. That is, the injection pipe 140 is connected to the upper end of the discharge pipe 130 so as to be bent at a predetermined angle. Accordingly, the mist discharged to the discharge pipe 130 is finally discharged to the outside through the spray pipe 140. In addition, the injection pipe 140 may be provided with an induction rod 143 so that the mist can be effectively injected through the injection pipe 140. Here, the guide rod 143 is supported by the injection tube 140 and extends to the outside of the injection tube 140. Since the guide rod 143 extends to the outside of the spray tube 140 in this manner, the mist sprayed to the spray tube 140 is moved along the guide rod 143 and the distance by which the mist is sprayed becomes longer It is effective. In addition, the induction rod 143 can be expanded and contracted in the longitudinal direction by connecting a plurality of segments, and the distance by which the mist is injected can be adjusted accordingly.

The air supply pipe 145 communicates with the discharge pipe 130 and the discharge pipe 140 and extends in the direction opposite to the discharge pipe 140. That is, the air supply pipe 145 is connected to the upper end of the discharge pipe 130 and extends in the direction opposite to the discharge pipe 140 with respect to the discharge pipe 130. Here, the air supply pipe 145 serves to additionally supply air. Specifically, the air supply pipe 145 may be provided with an auxiliary fan 147 for blowing air. Since the air blown to the auxiliary fan 147 moves in the direction of the spray pipe 140 from the air supply pipe 145 in this way, the mist can be effectively sprayed by the air blown by the auxiliary fan 147. In addition, a venturi tube 149 may be provided in the air supply pipe 145 so that the air blown by the auxiliary fan 147 can more effectively spray the mist. Specifically, the venturi pipe 149 is disposed closer to the spray pipe 140 than the auxiliary fan 147 so that the air blown by the auxiliary fan 147 passes. The venturi pipe 149 has a smaller cross sectional area than the injection pipe 140 at one end 149a near the injection pipe 140. As a result, the air blown by the auxiliary fan 147 increases in speed as it passes through one end 149a of the venturi pipe 149 having a relatively small cross-sectional area, so that the air that has passed through the venturi pipe 149 is discharged through the discharge pipe 130 It is possible to more effectively spray the mist that is discharged from the combustion chamber.

The water tub 110, the blowing tube 120, the discharge tube 130, the fan 127, the air filter 129, and the ultrasonic vibrator 113 of the humidifier according to the present embodiment, As shown in FIG. However, it is needless to say that the housing 100 shown in FIG. 1 is illustrative and that the scope of the present invention is not limited thereto, but can be manufactured in various forms.

2 to 5 are sectional views illustrating the operation of the humidifier according to the embodiment of the present invention. Referring to FIG. 2, the operation of the humidifier according to the present embodiment will be described.

2, before the humidifier is activated, the opening and closing unit 133a of the opening and closing unit 133 is closed and the discharge pipe 130 is closed. Therefore, foreign contaminants can be prevented from flowing into the water tub 110 through the discharge pipe 130. However, since the air introduced into the water tub 110 through the air blowing pipe 120 is purified by the air filter 129, the pollutants can be removed from the water tub 110, It does not flow into the water channel 110. In addition, the water stored in the water tank 110 can be sterilized by the ceramic ball 115 and can be prevented from being contaminated.

3, when the humidifier is operated, the fan 127 is driven to blow air purified by the air filter 129 toward the water tub 110 through the air blowing pipe 120. As shown in FIG. In addition, a mist is generated from water stored in the water tub 110 while the ultrasonic vibrator 113 is driven. Therefore, when air is supplied from the blowing pipe 120 and discharged to the discharge pipe 130, the mist is discharged to the discharge pipe 130 together with the air. Specifically, the air supplied to the water tub 110 through the blowing pipe 120 passes through the extension portion 125 of the blowing pipe 120 having a relatively small cross-sectional area, thereby increasing the speed and reducing the pressure. Accordingly, the mist is moved between the blowing pipe 120 and the discharge pipe 130, and is discharged to the discharge pipe 130 together with the air. As a result, the air supplied to the water tub 110 through the air blowing pipe 120 is directly discharged to the discharge pipe 130, so that the fine particles contaminated by the air in the water bath or the stored water can be prevented from being discharged.

4, the mist discharged into the discharge pipe 130 is sprayed to the discharge pipe 140 communicated with the discharge pipe 130. [ At this time, the auxiliary fan 147 provided in the air supply pipe 145 is driven to blow air in the direction of the spray pipe 140, so that the mist can be effectively sprayed. Further, the air blown by the auxiliary fan 147 passes through the venturi pipe 149 and increases in speed, so that the mist can be more effectively sprayed. On the other hand, the spray tube 140 is provided with an induction rod 143, and the mist is moved along the induction rod 143, so that the spray distance of the mist can be made longer.

Further, as shown in 5, when the mist is generated from the water stored in the water tub 110 using the ultrasonic vibrator 113, the amount of water is reduced. Accordingly, the water level sensor 150 senses the water level of the water, and when it is determined that the water level of the water is below the predetermined value, the storage tank 155 can supply water to the water tank 110 through the supply line 157.

6 is a cross-sectional view of a humidifier according to another embodiment of the present invention.

As shown in FIG. 6, the humidifier according to the present embodiment may be added with a dehumidifier 160. Specifically, when water stored in the water tray 110 is completely removed, and the dehumidifier 160 is connected to the blowing pipe 120, the water can be used to remove moisture in the air. Here, the dehumidifier 160 may be a freezer which cools the moisture in the air by cooling the temperature of the air, or a desiccant that adsorbs moisture in the air by using an adsorbent, or the like.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
