The present invention relates to an ultrasonic humidifier. More specifically, when it detects that the humidifier body integrally formed with a bucket for storing water and a humidification chamber for humidifying the external air and the water necessary for humidification, the power and external air used for humidification are supplied to the humidifier. It has a structure consisting of a main body , wherein the humidifier and the main body is separable, provided with a water outlet or water pipe at the lower end of the partition partitioning the water tank and the humidification chamber, the lower portion of the water tank It relates to an ultrasonic humidifier having a water supply port. In the humidifier of the present invention, since the entire process until water is supplied to the bucket and finally the water in the sprayed state is discharged to the outside is performed only inside the humidifier, when it is desired to clean the contamination that is likely to occur on the movement path of water Only the humidifier can be removed without moving the main body and can be easily cleaned ergonomically , preventing leakage to the outside even when the humidifier is tilted or collapsed by an external impact.

There are various methods of humidifier for humidifying dry indoor air. Ultrasonic humidifiers are widely used because of their superior spray generation efficiency compared to other methods. Figure 1 shows a typical structure of the ultrasonic humidifier of the prior art (a) is a separated state, (b) shows a combined state. As shown in Figure 1, the ultrasonic humidifier of the prior art is typically a bucket 210 for storing water ; A humidification chamber 220 generating a spray from the water supplied from the bucket 210 by the spray generator 300 to humidify the indoor air ; And when the water level detector 330 detects that the water necessary for generating the spray is sufficient, supplies an alternating current of high frequency corresponding to the resonance frequency of the ultrasonic vibrator used for generating the spray to the spray generator 300. And at the same time through the blower tube 350, the main body 100 for supplying the external air to the humidification chamber 220; has a structure consisting of.

The humidification chamber 220, a humidification tank 221 for temporarily storing the water supplied from the bucket 210, a water level detector 330 for detecting the water level of the humidification tank 221, the humidification tank 221 A spray generator 300 installed at the lower part to make the water stored in the humidification tank 221 into fine water particle spray by ultrasonic vibration, a blower tube 350 for supplying external air to be mixed with the spray, Cover 227 to form a closed space so that the spray and the outside air is smoothly mixed, provided on the cover 227 above the outlet 222 for discharging the spray, and coupled to the outlet 222 to the outside specific It consists of a spray nozzle 226 for effective spray spray in the direction. Here, the main parts of the humidification chamber 220, such as the humidification tank 221, the water level detector 330, the spray generator 300, and the blower tube 350, are all formed integrally with the main body 100, and thus, separation from the main body 100 is impossible. In addition, since only the cover 227 and the outlet 222 and the spray nozzle 226 can be separated, the main body 100 must be moved to clean the humidifier, in particular, the humidification tank 221.

On the other hand, the water tank 210 is provided with a water inlet 211 for replenishing water when the water is insufficient, the water supply valve 213 for supplying water to the humidification tank 221 Is provided at the bottom of the bucket 210. The water flow valve 213 normally acts to supply water to the humidification tank 221 by opening the water flow valve 213 when the water flow valve 213 is pressed by the protrusion 113 provided in the main body 100. At the same time, the spray generator 300 serves to maintain a constant level of the humidification tank 221 for a smooth spraying operation. The bucket 210 may be separated from the main body 100 to make it easier to move and replenish water.

However, if the above-described humidifier of the prior art is used for a long time, contamination by breeding of mold or bacteria in the water tank 210 and the humidifier tank 221 occurs seriously, and the humidifier for health rather than indoor air pollution. Cause. To prevent this, the water tank 210 and the humidification tank 221 should be washed frequently. At this time, since the water tank 210 is detachable and can be easily cleaned, as shown in FIG. 1, since the humidification tank 221 is integrally formed in the main body 100, it is very inconvenient to move and wash the main body 100. There are disadvantages. In addition, since the inside of the main body 100 is composed of an electronic circuit, there is always a risk of a malfunction of the humidifier due to damage to the insulation state of the electronic circuit due to the inflow of water during the cleaning or electric shock. Therefore, most consumers wash the water tank 210 frequently, but the cleaning of the humidification tank 221 is hardly performed, so the contamination of the humidification tank 221 proceeds more seriously. Therefore, even if clean water is not contaminated by washing the water tank 210 is supplied to the humidification tank 221 is mixed with the water of the humidification tank 221 already seriously polluted to humidify the indoor air, contamination of the humidification tank 221 Continues to accumulate, so the cause of indoor air pollution will only get worse over time.

In order to solve this problem, there is a method of injecting a chemical that suppresses the growth of mold or bacteria into the water, but the chemical is also mixed with humidified air and diffused into the room. There is a disadvantage of being added. Meanwhile, in the complex humidifier, a method of sterilizing mold or bacteria by heating the water in the humidification tank 221 to about 60 to 70 degrees Celsius is used. However, mold or bacteria that can survive even at a high temperature cannot be sterilized. In order to heat the power, which requires several times the power of the humidifier itself, it consumes a lot of power and has the disadvantage of increasing production costs.

On the other hand, according to the Republic of Korea Patent Publication KR10-0513693B1 and Publication No. KR10-2004-0073403A, a method capable of separately washing by having a structure in which the humidification chamber 220 is separated from the main body 100 separately from the water tank 210 Although it is being presented, there is a disadvantage in terms of the cause of the failure and production cost because the structurally complex fluid connection pipe (water supply passage) between the water tank 210 and the humidification chamber 220, the main body 100 There is no suggestion of a specific connection means (power transmission means, state detection and control means) between the spray generator and the spray generator 300. In addition, according to the Utility Model Registration No. KR20-0398711Y1, it is possible to separate the humidification chamber 220 by applying a contactless power transmission method between the main body 100 and the spray generator 300, but the main body 100 and the humidification chamber. Specific means of the connection means (status detection means) between the 220, the connection means (water supply means) between the water tank 210 and the humidification chamber 220 and the means for maintaining the level of the humidification tank 221 constant No contactless power transfer technology is already known to those skilled in the art.

On the other hand, the ultrasonic humidifier of the prior art has a disadvantage in that the water contained in the humidifier tank 221 leaks to the outside when the humidifier is inclined or collapsed due to an external impact to wet the outer bottom surface (hereinafter referred to as the ground). . This has the disadvantage of cleaning the ground, which is a very significant disadvantage especially in families with young children who lack situational judgment ability. Most households use a humidifier in the room used by the infant for the health of the infant, since the water spilled outside the humidification chamber 220 may wet the infant's clothes and cause a cold and a risk of electric shock. .

In addition, the ultrasonic vibrator is a part that is sensitive to scratches, so it is a part that requires careful attention when cleaning, and it is well known that it is a kind of consumable part because it has the shortest life span among the components of the ultrasonic humidifier, but in the prior art, the main body (100) ) Because it is formed integrally inside there is a disadvantage that there is no way to separate it easily wash or replace.

The present invention has been invented to solve the above-mentioned problems of the prior art, the first object of the present invention is easy to wash the contamination by the breeding of mold or bacteria, which is easy to occur when the humidifier is used for a long time, and water The present invention provides an ultrasonic humidifier with an ergonomic structure that automatically discharges contaminated water, which is a source of indoor air pollution when replenishing.

It is a second object of the present invention to provide an ultrasonic humidifier which prevents leakage to the outside even when the humidifier is tilted or collapsed by an external impact.

[First Example ]

Figure 2 is a view showing the structure of the humidifier of the present invention, (a) is a separated state, (b) shows a combined state. As shown in FIG. 2, the humidifier of the present invention includes a main body 100 and a humidifier 200. The main body 100 and the humidifier 200 can be easily combined and separated, and all the water movement processes between the final injection process of water from the outside from the injection of water from the outside and the humidifier 200 Since it is made only inside, it is possible to simply clean the humidifier 200 by moving separately without the need to move the main body 100 when the humidifier cleaning is required.

The humidifier 200 is provided with a water supply port 211 for injecting water from the outside and a water tank 210 for storing water used for humidification, and the water tank 210 by the spray generator 300. ) To generate a spray from water supplied from the water to humidify the external air, and then to form a humidifying chamber 220 to be discharged to the outside again through the outlet 222, the water tank 210 and the humidifying chamber 220 The water passage 202 or the water pipe 203 is provided in the lower end part of the partition 201 which divides ().

When the main body 100 detects that the water required for the operation of the humidification chamber 220 is sufficient by the water level detector 330, a high frequency corresponding to the resonance frequency of the ultrasonic vibrator included in the spray generator 300 While supplying an alternating current to the spray generator 300 and at the same time through the blower pipe 350 to supply the external air to the humidification chamber (220).

On the other hand, the spray generator 300, the water level detector 330, the blower tube 350, etc., which were provided integrally with the main body 100 in the prior art, are all provided in the humidifier 200 in the present invention. 100) and a means of connecting in terms of functionality.

Channel

In the humidifier of the present invention, since the water tank 210 and the humidifying chamber 220 are integrally formed and cannot be separated, the water flow valve 213 in the related art is unnecessary, and instead, the water tank 210 and the humidifying chamber 220 may be separated from each other. A water outlet 202 is installed for water supply. The water outlet 202 is installed at the lower end of the partition wall 201 separating the water tank 210 and the humidification chamber 220, the connection means between the water tank 210 and the humidification chamber 220 in terms of functionality It acts as a (water supply passage) and determines the water level of the humidification tank 221 at the time of operation of the humidifier. In addition, when replenishing water to the bucket 210, the water level of the bucket 210 is determined, since the water inlet 211 is provided in the lower portion of the bucket 210, because the inverted humidifier 200 during water replenishment. .

FIG. 11 is an enlarged view of the water outlet 202 of FIG. 2. When the water supply of the humidification tank 221 starts to be supplied to the humidification tank 221 through the water outlet 202 from the water tank 210 in the state where the humidification tank 221 is empty initially, the final humidification The water level of the tank 221 is not the upper end of the water passage 202, but rather a position (about 6 to 8 mm) lower than that as shown in Fig. 11A. This is due to the surface tension of water in a state where a balance of force between air pressure (a kind of vacuum state) and synthetic pressure of pressure by water weight (hereinafter referred to as water pressure) and atmospheric pressure in a closed space is shown. This is because the water film 205 is formed. At this time, even if the force imbalance occurs within the range of the surface tension, the water film 205 is not destroyed.

When the water level of the humidification tank 221 is finely lowered while the spray is generated by the spray generator 300, the water film 205 gradually increases downward as shown in FIG. At this time, the atmospheric pressure is almost constant, but the water level in the water tank 210 relative to the lower end of the water film 205 is relatively high (h2> h1), so that the lower end of the water film 205 increases the water pressure, so that the balance between atmospheric pressure and water pressure is increased. This gradually collapses. When the water film 205 becomes larger and cannot withstand the water pressure of the water tank 210, the water film 205 is destroyed and the water of the water tank 210 is supplied to the humidification tank 221 at a time so that the water level of the humidification tank 221 is It rises again. At this time, since the atmospheric pressure is higher than the water pressure of the bucket 210, the air in the atmosphere is supplied to the bucket 210 by the volume of the water supplied to the humidification tank 221. As the air moves to the upper portion of the water tank 210 while forming air bubbles, a new force balance is achieved between the atmospheric pressure and the water pressure, so that a new water film 205 is formed in the water passage 202. While repeating this process, the water level of the humidification tank 221 repeats the descending and rising within a narrow range, but the water level of the bucket 210 is continuously lowered.

When the water in the bucket 210 is further reduced so that the water level is lower than the top of the water outlet 202, the water tank 210 can no longer be a sealed space, so the water film 205 disappears and the water tank 210 and the humidifying tank ( The water surface of 221 is the same. Since the plane of the water tank 210 is much wider than that of the humidification tank 221, a large amount of water is suddenly supplied to the humidification tank 221 at the moment when the water film 205 disappears, so that the water level of the humidification tank 221 becomes high. do. At this time, the increase in the water level of the humidifier tank 221 is divided by the sum of the surface area of the water tank 210 and the humidifier tank 221 divided by the volume corresponding to the product of the water surface of the water tank 210 and the height of the water film 205. The maximum value is, of course, smaller than the height of the water film 205 immediately before the water film 205 disappears.

To prevent a sudden increase in the level of the humidification tank 221 when the water film 205 disappears, the surface area of the water tank 210 may be reduced when the water film 205 disappears. Figure 12 shows the shape of a bucket having such a structure, Figure 12 (b) shows a view of Figure 12 (a) viewed from the right side to aid in understanding the three-dimensional shape. However, since the height of the bucket 210 is reduced by h3, the amount of water stored in the bucket 210 is reduced, so the profit is not large.

On the other hand, it is well known that the amount of spray generation is constant and the static and dynamic water level change of the humidification tank 221 must be small in order to generate stable spray evenly sprayed. Accordingly, the water passage 202 is preferably a rectangular shape having a width of about 1 to 2 cm and a height of about 1 cm. The width and height are values obtained by the inventors' approximate experiment, so it may be found that there may be a significant error.

If the width of the water inlet 202 is too narrow, the surface tension in the horizontal direction is strong, the water film 205 is destroyed only when the water level of the humidification tank 221 is changed a lot, so the static water level change of the humidification tank 221 is severely changed. Not preferred. On the contrary, if the width of the water inlet 202 becomes too wide, the amount of water supplied increases every time the water film 205 is destroyed, so that the wave generated in the humidification tank 221 becomes large, and thus the dynamic water level change increases. At this time, since the size of the air bubbles generated in the water tank 210 is increased, the noise generated by the water is increased, which is not preferable. In the humidifier of the prior art, the noise was so severe that it became a significant stressor at night when the surroundings were quiet.

On the other hand, if the height of the water inlet 202 is too low, since the surface tension in the vertical direction is strong so that the water film 205 is not destroyed, the connection means (water supply) between the water tank 210 and the humidification chamber 220 in terms of functionality Does not work). In addition, if the height of the water outlet 202 is too high, the water level when replenishing the water is lowered and the capacity of the water tank 210 is reduced.

Water supply

The humidifier of the present invention has a water supply port 211 for replenishing water from the outside at the bottom of the bucket 210, for two reasons. First, in order to replenish water in the bucket 210 so that the consumer turns the humidifier 200 so that the contaminated water 207 remaining in the humidification chamber 220 is automatically discharged through the outlet 222. to be. Second, when replenishing the water in the bucket 210 is to fill the bucket 210 full of water without the outflow of water through the water outlet 202. If it is assumed that the water inlet 211 is in the upper portion of the water tank 210, since the water inlet 211 is open to replenish water, until the water level of the water tank 210 and the humidification tank 221 is the same. Water in the bucket 210 is continuously discharged to the humidification chamber 220 through the water outlet 202, it is not possible to fill the bucket full of water and maintain the proper level of the humidification tank (221).

Easy cleaning  And water replenishment process

The bucket 210 of the humidifier stores the amount of water that can be humidified normally about 8 to 12 hours. Therefore, if you use a lot of humidifiers at least once a day, even if not many times once a few days will replenish the water in the bucket (210). In general, when the consumer replenishes the water tank 210, the water tank 210 is washed, and then the fresh water 206 is replenished. In this case, even after several days, the mold or bacteria hardly reproduce, so that the soil is contaminated. The degree is very low. Nevertheless, the reason that contamination is a problem in the humidifier of the related art is because the consumer frequently washes the water tank 210 but the humidification chamber 220 including the humidification tank 221 does not wash for a long time. Another reason is that when the humidifier is not used for a long time, all water in the humidifier should be left empty to prevent contamination, but it is left for a long time without emptying the water. A more fundamental cause of these reasons is the hassle of moving the main body 100 in which the humidification tank 221 is installed in order to clean the humidification tank 221.

Since the humidifier of the present invention does not exist at all in the body 100, but only in the humidifier 200, the humidifier 200 can easily separate and move the water to move the water including the humidifier tank 221. Water can be added at the same time as the entire route is cleaned. 3 is a view for explaining a simple washing and water replenishment process of the present invention humidifier. If the contamination is not very serious, the following steps are taken.

(1) When the water filled in the bucket 210 is completely consumed by the humidification operation, as shown in FIG. 3 (a), the water remaining in the humidification tank 221 is used for the natural breeding of mold or bacteria. It becomes slightly polluted by.

(2) The consumer separates the humidifier 200 from the main body 100 to replenish the water in the bucket 210, and moves to a place where the water can be replenished, such as a kitchen sink or a toilet. At this time, the main body 100 detects the separation of the humidifier 200 and stops the humidification operation.

(3) When the humidifier 200 is inverted, the stopper 300 is opened, and the water of the bucket 210 is started to be replenished. As shown in FIG. 3B, the contaminated water remaining in the humidification tank 221 is shown. 207 is automatically discharged through the outlet 222.

(4) When the water tank 210 is filled with water, the consumer closes the stopper 300, and then reverses the humidifier 200 again to the place where the main body 100 is located as shown in FIG. Move. At this time, the humidification tank 221 is filled with clean water 206 through the water inlet 202.

(5) When the consumer combines the humidifier 200 with the main body 100 again, the main body 100 detects the coupling of the humidifier 200 and resumes the humidification operation.

It should be noted here that there is no conscious cleaning process of the consumer among the above processes. If you use a lot of humidifiers are often supplemented with water, so little contamination occurs, simply by going through the above process is to ergonomically simple washing and water replenishment.

On the other hand, when the contamination is a little serious because the humidifier is not used a lot, it is possible to wash the contamination by rinsing the bucket 210 and the humidification chamber 220 once with clean water in the middle of the above (3) process. If the humidifier is left unused for a long period of time and the contamination is very serious, it should be wiped with a soft cloth or the like by putting a hand inside the bucket 210 and the humidification chamber 220. Therefore, from the viewpoint of the washing of the water tank 210 and the humidification chamber 220, the water inlet 211 and the outlet 222 is preferably a large hole size so that the hand of an adult male.

On the other hand, the purpose of easy coupling and separation between the main body 100 and the humidifier 200 during the simple washing and water replenishment process and the purpose of maintaining the stable posture in contact with the ground when the humidifier is temporarily separated. In order to achieve this, the lower portion of the humidifier is provided with a coupling member 204. In addition, a handle (not shown) may be provided on the humidifier for convenience when carrying the humidifier.

It is said that the water outlet 202 is located at the lower end of the partition wall 201 for easy washing and water replenishment, but it is not determined which position among the lower ends of the partition wall 201. Now, various cases in which the humidifier is collapsed by external impacts will be examined to determine a more detailed and desirable position for preventing leakage to the outside. In conclusion, in the humidifier having the structure as shown in FIG. 2, the position of the water outlet 202 is more specific than the rearmost part of the bottom of the partition 201 (upper part in the down state, the lower part in the back state) or the front part. (The lower part in the down state, the upper part in the back state).

Normally, the humidifier is called the front face F, which has an operation part for controlling its operation, and when viewed from the top view, the humidifier has a shape that is longer in length than in length. For convenience, the embodiment of the present invention is assumed to assume that the humidifier has such a shape. Here, the front (front, F) and the rear (back, B) are merely differences in perspective and the same principle applies as far as the position of the water outlet 202 relative to the leak prevention structure is concerned. In addition, the front and rear and left and right directions are also differences in viewpoints. In addition, there may be a humidifier in a shape that is outside of the above assumptions in terms of differentiated design, but basically the same principle applies to differences in viewpoints. Therefore, even if only one case is described, it is possible to generalize to cover all cases due to the difference in viewpoint. Hereinafter, the position of the water outlet 202 in the humidifier having the shape of the home described above is the most at the bottom of the partition 201. Only the case of the rear side (the upper end of the bulkhead in plan view) will be described.

Figure 4 (a) is a case where the front surface (F) of the humidifier of the present invention is in contact with the ground (G), Figure 4 (b) shows a case where the humidifier rear surface (B) is in contact with the ground (G). As shown in FIG. 4A, when the front surface F of the humidifier falls down in contact with the ground G, the water level of the water tank 210 is lower than the position of the water inlet 202 so that the humidifier chamber from the water tank 210 can be found. There is no outflow of water to the 220, and since the water level of the humidification chamber 220 by the water in the humidification tank 221 is lower than the position of the outlet 222 or the blower pipe 350, there is no leakage to the outside of the humidifier. On the other hand, as shown in (b) of FIG. 4, when the rear surface B of the humidifier is in contact with the ground G, water in the humidification tank 221 blocks the water inlet 202 and the humidification chamber 220. Since air cannot flow from the bucket 210 to the bucket 210, there is no leakage of water from the bucket 210 to the humidification chamber 220, and there is no leakage to the outside of the humidifier for the same reason as in FIG. Here, the outlet 222 and the blower tube 350 should be located at approximately an intermediate point between the front side F and the rear side B, and it can be seen that the humidifier chamber is higher than the water level of the humidification chamber 220 even if the humidifier falls down either side. .

Since the humidifier of the present invention shown in the first embodiment has a rectangular shape in plan view, the case where the side length is smaller, that is, the left and right sides fall down to contact the ground surface G, is considerably low. 5A illustrates a case where the right side R is in contact with the ground surface G, and FIG. 5B illustrates a case where the left side L is in contact with the ground surface G. FIG. As shown in (a) of FIG. 5, when the humidifier has fallen so that the right side R contacts the ground G, the water in the humidification tank 221 flows back into the water tank 210 and the outlet 222 or There is no leakage to the outside of the humidifier through the blower tube 350. As shown in FIG. 5B, when the left side L falls down to contact the ground G, the water in the humidification tank 221 does not block the water inlet 202 so that the water in the bucket 210 may be reduced. The humidification chamber 220 continues to flow out. Accordingly, when the water level of the humidification chamber 220 becomes higher than the position of the discharge port 222 or the blower pipe 350, leakage to the outside of the humidifier occurs. In order to solve this problem, as shown by a dotted line in Fig. 5B, the outlet port 202 is replaced with a water pipe 203 so that the outlet is locked by the water of the humidification tank 221. Since the air cannot be introduced into the bucket 210, a balance is achieved between the atmospheric pressure and the water pressure inside the bucket 210, thereby preventing the flow of water from the bucket 210 to the humidification chamber 220.

A more preferable way to solve the above problem is that the external shape of the humidifier itself does not allow the side to contact the ground (G). As seen from the top view of the humidifier, as shown in Fig. 6, the front and rear sides have a flat shape, and the left and right sides have a non-flat shape (semi-circle or other convex shape), and the left and right sides have a stable seating on the ground (G). By disabling, even if the left and right sides are in contact with the ground (G) first by the external impact, the front (F) or the rear (B) is finally in contact with the ground (G). That is, the front (F) and the rear (B) is the seating side, the front and rear direction is the mounting direction. Figure 6 (a) is a case where the front surface (F) of the humidifier of the present invention is in contact with the ground (G), Figure 6 (b) shows a case where the humidifier rear surface (B) is in contact with the ground (G). In this case, the principle that water leakage from the water tank 210 to the humidification chamber 220 and the principle of no leakage to the outside of the humidifier are the same as in FIG. 4, and thus description thereof is omitted.

It should be noted that the concept of flatness is a relative concept, and does not mean a partial plane but is used to mean that the radius of curvature is large. This is consistent with dictionary meanings and social notions. Although the left and right side surfaces L and R have a planar shape and the front side F and the rear side B have convex shapes, if the length of the left and right directions LR is considerably longer than the length of the front and rear directions FB, In general, the radius of curvature of the front and rear surfaces (F, B) is relatively larger than that of the left and right sides (L, R), and the front (F) and the rear (B) are the seating sides and the front and rear directions ( FB) becomes the seating direction. In this case, unless the left side L or the right side R is intentionally erected to come into contact with the ground, any one of the left and right sides falls first in contact with the ground when the humidifier falls by an external impact. As one side of the front and rear surfaces are in contact with the ground to be seated.

Meanwhile, referring to the internal structure of the humidifier 200 in FIG. 6, a partition wall 201 is formed in the seating direction, and a bucket 210 and a humidification chamber 220 are disposed at both sides thereof, and an outlet 222 and The position in the seating direction of the blower pipe 350 is approximately an intermediate point in the humidification chamber 220, and the position of the water passage 202 provided in the partition wall 201 is the lower end of the partition wall in the front view, but the seating side (rear view) in the plan view. , B) is the point where the distance (h4) of the mounting direction (front and rear, FB) is minimized.

Although it is a very rare probability, we can think of the case where the humidifier is completely turned upside down by the external strong impact and the upper surface is in contact with the ground (G). In this case, since the position of the water outlet 202 is higher than the water level of the water tank 210 as shown in FIG. 3 (b), there is no water leakage from the water tank 210 to the humidification chamber 220, but the humidification tank ( Leakage outside the humidifier by water contained in 221 is unavoidable. Therefore, it is necessary to minimize the amount of water contained in the humidification tank 221 in the normal operating state.

On the other hand, in order to equalize the size of the spray particles and increase the spray generation efficiency of the ultrasonic vibrator 301, the water level of the humidification tank 221 should be maintained at a constant value determined by the characteristics of the ultrasonic vibrator 301 used. Known. For example, the resonant frequency of an ultrasonic vibrator that is frequently used in a humidifier is 1.65 MHz, and the level of spray generation efficiency is 38 mm. If the water level is higher or lower than this, the spraying efficiency is lowered. Therefore, in order to minimize the amount of water contained in the humidification tank 221, it is not possible to lower the level of the humidification tank 221 unintentionally, and to minimize the amount of water contained in the normal condition of the humidification tank 221 level. Humidifier should be a structure (221).

outlet

On the other hand, when the humidifier 200 is collapsed by the external shock in more detail, the water contained in the humidifier tank 221 is sharply directed toward the discharge port 222 by the impact is to hit the upper surface of the humidifier. . If the impact is quite large, the water hitting the upper surface is likely to leak and then leak out through the outlet 222 by inertia. FIG. 13 is a view showing that the water barrier 223 is provided under the outlet 222 as a means for preventing leakage due to such a situation. 222) A detailed perspective view of the portion. As shown in FIG. 13, a cylindrical water barrier 223 is installed along the outer circumferential surface of the discharge hole 222 below the outlet 222, and the water barrier 223 is side-slit 224 in the left-right direction (L-R) of the humidifier. It is provided. When the humidifier 200 is inverted in the above-described simple washing and refilling process, the side slit 224 serves to smoothly discharge the water in the humidification tank 221.

FIG. 14 is a detailed cross-sectional view of a portion of the outlet 222 for showing the principle of operation of the water barrier 223, and shows the case in which the humidifier 200 is brought down by contacting the front surface F of the humidifier 200. FIG. At the moment when the external shock is applied and the humidifier collapses, the water in the humidifier 221 moves along the leakage preventing path 225 indicated by the arrow in FIG. 14 to collide with the upper surface of the humidifier 200, and then the water barrier Since the direction of the water movement path is changed toward the humidification tank 221 by colliding with 223 again, the water barrier 223 prevents leakage to the outside through the outlet 222.

Meanwhile, when the humidifier is operated, the spray nozzle 226 is coupled with the outlet 222 to prevent the side frame 224, thereby helping to prevent leakage when the humidifier is collapsed by an external impact. Therefore, the spray nozzle 226 should not be easily separated from the outlet 222 even in the external impact. In addition, the water barrier 223 may be long enough so that its length reaches a position higher than the humidification tank 221. This not only prevents leakage, but also helps to mix the spray and the outside air well enough. At this time, the side trim 224 is preferably replaced by a hole.

Spray generator

In order to clearly compare the technical differences between the spray generator 300 and the prior art spray generator 300 of the present invention, the structure of the spray generator 300 of the prior art will be briefly described. First, according to the acoustic engineering technology for the main pipe, the acoustic impedance matching between the sound source and the medium is made to maximize the efficiency of converting electrical energy into acoustic energy, and the horn 304 is commonly used as the impedance matching means. do. A representative example thereof may be a megaphone. Therefore, the horn 304 is required as an acoustic impedance matching means between the sound source (spray generator, more precisely the ultrasonic vibrator) and the medium (water in the humidifier) of the ultrasonic humidifier to increase the efficiency. In addition, the horn 304 helps to minimize the amount of water contained in the humidification tank 221 under the condition that the water level of the humidification tank 221 is kept constant.

15 is an enlarged view of the spray generator 300 in the ultrasonic humidifier of the prior art. In the ultrasonic humidifier of the prior art, the humidification tank 221 is provided integrally with the main body 100 on the upper part of the main body 100, and the horn 304 is normally screwed by using several first screws thereunder. Attached. The horn 304 is usually manufactured by using a metal material having excellent thermal conductivity because the power semiconductor used in the driving circuit of the ultrasonic vibrator 301 is attached to the horn 304 and cooled. In other words, the horn 304 also serves as a heatsink. On the other hand, the spray generator 300 is installed by installing the ultrasonic wave oscillator 301 of the disc shape obliquely on the inner circumferential surface of the cylindrical bushing 302 made of an elastic material such as rubber and then mounted it inside the cylindrical housing 303 In the configuration, the housing 303 is again attached to the lower portion of the horn 304 by screwing using several second screws. The reason why the ultrasonic vibrator 301 is inserted at an angle is to maintain a relatively smooth acoustic impedance match despite the minute water level change of the humidification tank 221. On the other hand, since the spray generator 300 is provided in the main body 100, the driving circuit directly supplies power to the ultrasonic vibrator 301 through the driving wire 103.

On the other hand, the spray generator 300 according to the present invention is installed by inserting the disk-shaped ultrasonic vibrator 301 obliquely on the inner circumferential surface of the cylindrical bushing 302 made of elastic material such as rubber, and transmitted from the main body 100. The power receiver 311 that transmits the received high frequency AC current to the ultrasonic vibrator 301 is installed under the bushing 302, and then all of them are mounted inside the cylindrical housing 303. On the other hand, the horn 304 is integrated with the humidification chamber 220 is installed in the lower portion of the humidification chamber 220, and the male screw 305 is formed on the outer circumferential surface of the lower end of the horn 304 and then the male screw 305 and The female thread 306 is formed on the inner circumferential surface of the upper end of the housing 303, so that the horn 304 and the horn are formed by the elasticity of the bushing 302 when the male screw 305 and the female screw 306 are coupled to each other. The spray generator 300 is watertightly coupled, and achieves acoustic impedance matching between the ultrasonic vibrator 301 and the water of the humidification tank 221. Means for connecting the spray generator 300 with the main body 100 is implemented by having a power transmitter 310 at a position above the main body 100 corresponding to the position of the power receiver 311.

16 and 17 show the structure of the spray generator 300 of the present invention, Figure 16 shows a contact method for supplying power to the ultrasonic vibrator 301 through electrical contacts, Figure 17 is a magnetic induction (magnetic) It shows a contactless method of supplying power to the ultrasonic vibrator 301 by induction.

As shown in FIG. 16 (b), the power receiver 311 in the contact method is formed such that the circular contact 313 and the annular contact 314 coincide with each other on the disk-shaped printed circuit board 312. Is implemented. Meanwhile, as shown in FIG. 16C, the power transmitter 310 has two elastic contacts 315 at positions above the main body 100 corresponding to the positions of the circular contact 313 and the annular contact 314. It is provided by having. In this case, the elastic contact 315 functions to stably maintain contact between the contacts by elasticity when the humidifier 200 and the main body 100 are coupled to each other.

Meanwhile, the power transmitter 310 and the power receiver 311 in the contactless method are implemented by coils wound on the magnetic core 316 that can be separated. 17 (b) shows a cross section of the power transmitter 310 and the power receiver 311. The pot-shaped magnetic core 316 is divided in half, and then wires are wound around each of them. The coil 318 and the receiving coil 317 are implemented. However, if the two magnetic cores are coupled to each other and can form a closed circuit to maintain a close coupling state, the transmitting coil 318 and the receiving coil 317 are not necessarily wound around the magnetic core 316 of the same shape. It is well known that the shape of each magnetic core 316 can be variously changed. Furthermore, an air core coil without using the magnetic core 316 may be used.

The transmitting coil 318 and the receiving coil 317 act as a primary coil and a secondary coil of a detachable high frequency transformer, respectively, and when the main body 100 and the humidifier 200 are combined, they are magnetically coupled to form one complete high frequency wave. By operating as a transformer, the connecting means between the humidifier 200 and the main body 100 can be configured in a contactless manner by magnetic induction without exposing the electrical contact to the outside.

Meanwhile, the power transmission efficiency can be increased by configuring the primary side and / or secondary side circuits of the high frequency transformer to be a resonant circuit operating at a frequency corresponding to the resonant frequency of the ultrasonic vibrator 301. The resonant circuit may use a series resonant circuit or a parallel resonant circuit. However, the stray capacitance present between the electrodes of the ultrasonic vibrator 301 is much larger than the intrinsic capacitance of the ultrasonic vibrator 301 when viewed on an equivalent circuit of the ultrasonic vibrator 301. In order to cancel the effect of the secondary side parallel resonant circuit that connects the resonance coil 319 in parallel with the ultrasonic vibrator 301 is preferable. In this case, the resonant coil 319 forms a parallel resonant circuit together with the stray capacitance, and FIG. 17A shows an example in which a resonant circuit using the resonant coil 319 is configured.

In the above description, the advantages of the inventive spray generator 300 over the prior art spray generator 300 become apparent. First, when replacing or cleaning the spray generator 300, the invention can be easily separated by lifting the humidifier 200 by rotating the spray generator 300 attached to the lower by hand, in the prior art, the main body ( Opening 100) requires a very complex procedure since the second screw 102, which is coupled to the horn 304 with the spray generator 300 with a screwdriver, can be removed. Spray generator 300 is a kind of consumable parts and should be easy to replace. Second, in the invention technology, since the horn 304 is integrally formed using the same material (usually plastic) as the humidifier 200 under the humidifier 200, it is structurally simple, requires no assembly process, and has low production cost. In the prior art, since the horn 304 is a separate part that is cast using a metal material, the assembly process is complicated and the production cost is high. On the other hand, there is no cooling measures of the power semiconductor in the invention technology, which is solved by using a general-purpose heat sink inside the main body 100.

Water level detector

Before describing the means for connecting the water level sensor 330 to the main body 100, the float 331 switch generally used as the water level sensor 330 in the humidifier of the prior art will be described with reference to FIG. As described above, the float switch is composed of an annular float 331 and a rod-shaped induction pipe 332. The float 331 usually includes a permanent magnet therein, and has a specific gravity smaller than that of water so that the float 331 moves up and down along the induction pipe 332 to indicate the level of the humidification tank 221. Inside the induction pipe 332 is a reed switch (reed switch) commonly used as a magnetic sensor 334 in response to the magnetic field of the permanent magnet is installed at a position corresponding to the float 331, the water level of the humidification tank 221 Is the normal level, the switch contact is shorted (switch on), and when the level is low, the switch contact is switched off (switch off). The main body 100 determines that the water in the humidification tank 221 is sufficient when the switch contact state is a short-circuit state and maintains a humidification operation. When the switch contact state is open, the water shortage state of the humidification tank 221 is maintained. Judging by it, stop the humidification operation. Here, the magnetic sensor 334 for detecting the magnetic field may be a Hall device as well as a reed switch.

In the humidifier of the present invention, since all movement paths of water exist only in the humidifier 200 in which the bucket 210 and the humidification chamber 220 are integrally formed, the float 331 must be provided in the humidifier 200. The level of the humidification tank 221 can be detected. Therefore, the means for connecting the float switch with the main body 100 can be achieved by providing a connection contact in the lower portion of the induction pipe 332 and a connection contact coupled to the upper portion of the main body 100.

More preferably, as shown in Fig. 2 or 18 (a) in the float switch of the prior art is provided with a sensing tube 333 that can be inserted into the induction tube 332 on the main body 100 and the lid therein By providing a switch, the connecting means between the float switch and the main body 100 can be configured without exposing the electrical contact to the outside. On the other hand, when the humidifier 200 is separated from the main body 100, the float switch contact is opened, so the main body 100 stops the humidification operation regardless of whether the level of the humidification tank 221 is normal. That is, the water level detector 330 not only detects that the water necessary for the operation of the spray generator 300 is sufficient, but also functions to detect whether the main body 100 and the humidifier 200 are coupled.

Meanwhile, since the water tank 210 and the humidification chamber 220 are separated from the conventional humidifier, the water level sensor 330 must detect the water level of the humidification tank 221, but the humidifier of the present invention is the water tank 210 and the humidification chamber. Since the 220 is integrally formed, the water level sensor 330 does not necessarily sense the level of the humidification tank 221, and may directly achieve the same purpose even by directly detecting the level of the water tank 210. When the water level sensor 330 is installed in the water tank, the humidification chamber 220 can be made very small, including the humidification tank 221, and thus the humidification body 200 having a highly desirable leak prevention structure can be manufactured.

Figure 18 (b) ~ (d) shows a case of directly detecting the water level of the bucket 210. 18 (b) is provided with an induction pipe in the lower portion of the water tank 210 and provided with an annular float 331 so as to move up and down along the outer circumferential surface of the induction pipe, and then It is shown that the magnetic sensor 334 is provided at the corresponding position. 18 (c) is a cylindrical induction pipe 332 is installed in the lower portion of the water tank 210, but the water in the water tank 210 by drilling a water hole 335 in the upper and lower portions of the induction pipe 332 It is shown that the magnetic sensor 334 is provided at a corresponding position on the upper part of the main body 100 after inserting the cylindrical float 331 into the inside of the induction pipe 332. Figure 18 (d) is connected to the float 331 on one end of the rod 336, and the other end of the rod 336 is coupled to the lower portion of the bucket 210 and the hinge (hinge, 337) to the bucket 210 According to the water level of the float 331 is to move up and down and then the magnetic sensor 334 at the corresponding position on the upper portion of the main body 100 is shown.

18 (b) to (d), since the magnetic field is detected when the water in the water tank 210 is completely emptied, as opposed to the case of FIG. 18 (a), between the humidifier 200 and the main body 100. Means for determining whether the coupling of the separately required, a micro switch (micro switch), a magnetic sensor, a photo interrupter (photo interrupter) may be used.

Blower

In the humidifier of the related art, the blower tube 350 is integrated with the main body 100 to form the humidification chamber 220, but the blower tube 350 of the present invention should be provided in the humidifier 200 and be separated from the main body 100. , A means for connecting the blower tube 350 to the main body 100 is required. This is provided with a connection pipe 351 on the upper part of the main body 100 so that when the humidifier 200 and the main body 100 are coupled, as shown in FIG. 3, the connection pipe 351 is inserted into the blower tube 350. Is achieved. In this case, it is preferable to prevent air from leaking from the connection portion between the connection pipe 351 and the blower pipe 350 for efficient blowing. The outer diameter of the connecting pipe 351 and the inner diameter of the blower tube 350 is exactly the same, or the upper part of the main body having an annular hermetic member having an elastic such as a rubber plate surrounding the connecting pipe 351, the humidifier ( The object can be achieved by pressing the airtight member by the weight of 200). Here, the blower pipe 350 may be inserted into and coupled to the inside of the connection pipe 351. In view of airtightness, the air is blown because the minute gap between the blower pipe 350 and the connection pipe 351 is in the same direction as the flow of air. Although it is a small amount, the possibility of leakage is high, which is not preferable to the former method. On the other hand, the external air supplied from the outside of the humidifier is preferably used to cool the heat generated in the electronic circuit, etc. inside the main body 100 is preferably supplied to the humidification chamber 220 through the connection pipe 351 and the blowing pipe 350. .

[Second Example ]

Humidifier 200 structure of the humidifier of the present invention shown in the first embodiment described above is a humidifier chamber 220 on the left side, the bucket 210 is disposed on the right side based on the partition 201, in terms of design When the humidification chamber 220 is disposed inside the bucket 210 can be considered. An alternative shape of the humidifier of the present invention shown in the second embodiment is a dome shape in which the front and rear directions are pressed flat. Fig. 7 is a front view of this structure as seen from the front face (F) direction. In the first exemplary embodiment, only the side surfaces of the humidifying chamber 220 and the water tank 210 are in contact with the partition wall 201. Thus, the partition wall 201 surrounds all of the humidification chambers. In the figure, the water level detector 330 is not shown, and only the main part shows the name.

8 is a view for explaining a simple washing and water replenishment process of the present invention humidifier. The detailed operation is the same as that of the first embodiment, and thus will be omitted.

9 and 10 show a case in which the humidifier of the present invention is knocked down by an external impact. Figure 9 (a) is a case where the front surface (F) of the humidifier of the present invention is in contact with the ground (G). In this case, since the upper end of the humidification chamber 220 is lower than the water level of the water tank 210, a water pipe 203 is used instead of the water hole 202, and the end thereof is higher than the water level of the water tank 210. The outflow of water from the 210 to the humidification chamber 220 should be prevented. Figure 9 (b) shows a case in which the back of the humidifier (B) is in contact with the ground (G). In this case, the water in the humidification tank 221 blocks the water supply pipe 203 so that air cannot flow from the humidification chamber 220 into the bucket 210, so that the water from the bucket 210 to the humidification chamber 220 is removed. There is no spill. In both cases, since the water level of the humidification chamber 220 is lower than the position of the outlet 222 or the blower pipe 350, there is no leakage to the outside of the humidifier.

On the other hand, by making the center of the humidification chamber 220 seen in the plan view eccentric without matching the center of the water tank 210, it may be used instead of the water pipe 203. 10A illustrates a case where the front surface F is in contact with the ground surface G, and FIG. 10B illustrates a case where the rear surface B is in contact with the ground surface G. FIG. In this case, the center of the humidifier chamber 220 is eccentric from the center of the water tank 210 so that the position of the water outlet 202 is higher than or equal to the water level of the water tank 210 to leak the outside of the humidifier. It is preventing. In FIG. 10, the humidification chamber 220 may not be eccentric only in the up and down direction, and may be in the left and right directions as long as the position of the water outlet 202 is higher than the water level of the water tank 210.

Meanwhile, referring to the internal structure of the humidifier 200 in FIGS. 9 and 10, since the bucket 210 surrounds the humidification chamber 220, the partition 201 is formed all around the humidification chamber 220, and the outlet port is formed. The position of the seating direction of the 222 and the blower tube 350 is approximately an intermediate point in the humidification chamber 220, and the position of the water outlet 202 or the water pipe 203 provided in the partition wall 201 is in front view. Although it is the lower end of a partition, in the plan view, the distance h4 of the mounting direction (rear direction, FB) with any one seating side surface (rear surface B) is minimized.

It should be noted that, unlike the first embodiment, in the second embodiment, not only the left and right side surfaces but also the upper surface has a convex shape (dome shape) such that stable mounting on the ground surface G is impossible. Therefore, even if the upper surface is first contacted with the ground (G) by the external strong impact, the front (F) or the rear surface (B) is finally in contact with the ground (G) to be seated. Therefore, there is only a slight leakage at the moment when the external surface is first contacted with the ground (G), and after that, no leakage to the outside of the humidifier occurs.

On the other hand, although it is not preferable from the design point of view, it is possible to have a shape in which the humidifier does not fall down even when the external impact occurs, which is a case where the height is relatively low compared to the planar dimension of the humidifier. For example, a humidifier designed with a very low height with a square or circular top view. In this case, since the humidifier does not fall sideways in the external impact, the location of the water outlet 202 or the water pipe 203 may be any position of the partition 201 as long as it is the lower end of the partition 201, and the principle thereof is self-explanatory. Not shown.

The above detailed description of the configuration of the present invention and the preferred embodiments thereof, the present invention is not limited to the above-described typical preferred embodiments, but various improvements, modifications, It may be easily understood by those of ordinary skill in the art that the present invention may be substituted or added. If the implementation by such improvement, change, replacement or addition falls within the scope of the appended claims, the technical idea should also be regarded as belonging to the present invention.
