  • Said base unit (100) and humidifying unit (200) can be easily coupled and separated. And all water- flow routes from the water injection process to the final discharge process are resident inside of the humidifying unit (200). Therefore, the humidifying unit (200) can be easily separated from the base unit (100), moved and washed without the need to move the base unit (100), when the humidifier-cleaning is needed.
  • Said humidifying unit (200) which is unified to a single body and comprises a water tank (210) which stores the water used for humidification, and a spraying chamber (220) which humidifies the external air supplied through the blast pipe (350) by generating a spray from the water supplied from the water tank (210) with the spraying generator (300) and discharges the humidified air through a vent (222).

  • the base unit (100) if it senses with the level sensor (330) that the necessary water is sufficient for the operation of the humidifying chamber (220), it supplies the external air to the humidifying chamber (220) through the blast pipe (350), and the alternating current of the high frequency corresponding to the resonant frequency of the ultrasonic vibrator included in the spraying generator (300) to the spraying generator (300).
  • Fig. 11 is a drawing augmenting the water-feeding hole (202) part of Fig. 2.
  • the water-film (205) is unable to withstand the water pressure of the water tank (210) when the water-film (205) is enlarged sufficiently, the water-film (205) is destroyed, then the water of the water tank (210) is provided to the humidifying bath (221) at a time, then the water level of the humidifying bath (221) is recovered.
  • the air among an atmosphere is supplied to the water tank (210) as much as the volume of the water supplied to the humidifying bath (221) since the atmospheric pressure is instantaneously higher than the water pressure of the water tank (210). Since this air forms the air bubbles and moves to the upper part of the water tank (210), a new balance of the force between the atmospheric pressure and water pressure is built.
  • a new water-film (205) is formed in the water-feeding hole (202). While repeating this process, the water level of the humidifying bath (221) repeats a lowering and rising in the narrow range, but the water level of the water tank (210) continues to go lower.
  • the incremental water level of the humidifying bath (221) becomes the value dividing the volume corresponding to the value multiplying the plane area of the water tank (210) and height of the water-film (205) by the sum total of the water surface area of the water tank (210) and humidifying bath (221).
  • the maximum value is smaller than the height of the water- film (205) that disappeared just before.
  • Fig. 12 shows the shape of the water tank having the structure of being like that.
  • (b) shows the drawing looked at (a) in the right side of (a), in order to help the understanding of three-dimensional shape. But since the height of the water tank (210) is decreased as much as h3, the volume of the water contained in the water tank (210) is reduced. Therefore the actual profit is not big.
  • the present invention humidifier has the inlet port (211) on the lower part of the water tank (210) for replenishing the water from an outside.
  • Second objective is to fill the water into the water tank (210) fully without any leak of the water through the water- feeding hole (202) when replenishing the water in the water tank (210). If it is assumed that it has the inlet port (211) on the top of the water tank (210), the water of the water tank (210) is continuously flowed out into the humidifying chamber (220) through the water-feeding hole (202) until the water levels of the humidifying bath (221) and water tank (210) are identical, since the inlet port (211) is in the open state in order to replenish the water. Therefore, the water tank (210) cannot be filled fully with the water, and the water level of the humidifying bath
  • the water tank (210) of a humidifier stores an amount of the water to humidify about 8 - 12 hours. Therefore, the water tank (210) is replenished with the water at least one time per day in case of heavy use of the humidifier, or one time in several days even in case of light use.
  • a consumer fills up the clean water (206) after washing the water tank (210). In this case, it is rare to be polluted because the mold or the bacteria nearly is unable to propagate although several days are passed.
  • the reason why the contamination becomes a problem is that the consumer dose not wash the humidifying chamber (220) including the humidifying bath (221) for a long term although he/she frequently washes the water tank (210). And the other reason is that, in case of not using the humidifier for a long term, he/she leaves the humidifier in the state of not empty of water, although all waters within the humidifier must be emptied in order to prevent the contamination.
  • the more essential source of those reasons is the troublesomeness of moving the base unit (100) in which the humidifying bath (221) is installed, for the washing of the humidifying bath (221).
  • the water movement route does not exist inside the base unit (100) at all and it exists only inside the humidifying unit (200). Therefore, after conveniently separating the humidifying unit (200) from the base unit (100) and moving the humidifying unit (200), the consumer can wash the whole water movement route that includes the humidifying bath (221), and can replenish the water of the water tank, at the same time.
  • Fig. 3 is a drawing for illustrating the easy-cleaning and water replenishing process of the present invention humidifier. In case the contamination is not so serious, the procedures described in the following are processed.
  • the base unit (100) senses the bind of the humidifying unit (200) and again starts the humidifying operation.
  • a humidifying unit is equipped with several combining members
  • the humidifying unit in the lower part of the humidifying unit in order to achieve objectives which are easy union/separation of the humidifying unit and base unit (attachment/detachment of the humidifying unit to/from the base unit), and maintaining the stabilized posture of the humidifying unit in contact with the ground if it is provisionally put on the ground, during the easy-cleaning and water-replenishing procedure.
  • the humidifying unit can be furnished with a handle (not illustrated) for the convenience of lifting and moving the humidifying unit.
  • the water- feeding hole (202) is positioned in the lower part of the partition (201) for easy washing and water replenishing. However it is not yet determined exactly where it should be located in the lower part of the partition (201). It is time to determine the detailed and desirable location of the water-feeding hole for the prevention of water leakage, considering various cases where a humidifier tumbles down with an external impact.
  • the location of the water- feeding hole (202) in the humidifier with the structure as shown in Fig. 2 should be either at the back-end in the lower part of the partition (201) (the top when tumbling down forwards, and the bottom when tumbling down backwards), or at the front-end (the bottom when tumbling down forwards, the top when tumbling down backwards).
  • the front (F) of a humidifier has a shape in which a width is longer than a depth when viewed from above.
  • a humidifier has such a shape.
  • front (F) and back (B) are just difference of the point of view, the same principle is applied as far as the location of the water- feeding hole (202) is concerned.
  • backward-forward axis and left?right axis are another difference of the point of view.
  • a humidifier for the sake of design differentiation, could have a shape different from the assumption described above, it is still the difference of the point of view and the same principle shall be applied.
  • FIG. 4 shows the case where the front (F) of the present invention humidifier contacts with the ground (G), while (b) shows the case where the back (B) contacts with the ground (G).
  • the water level of the water tank (210) is lower than the location of the water-feeding hole (202) and there is no flow of water to the humidifying chamber (220) from the water tank (210).
  • the water leak out of the humidifier since the water level of the humidifying chamber (220) by the water in the humidifying bath (221) is lower than the location of the vent (222) and the blast pipe (350).
  • the water level of the humidifying chamber (220) is lower than the location of the vent (222) and blast pipe (350) regardless of the side to which the humidifying chamber tumbles down, if both are positioned at approximately the middle of the front (F) and back (B).
  • the mouth of the water-feeding canal (203) is sunk in the water of the humidifying bath (221), which prevents the external air from flowing into the water tank (210), and therefore the balance between water pressure in the water tank (210) and atmospheric pressure in the humidifying chamber (220) prevents water outflow from water tank (210) into humidifying chamber (220).
  • a more desirable method for resolving the problem is that the external shape of a humidifier precludes to the possibility that the left or right side contacts with the ground (G).
  • the outer shape of the humidifier is so made that its front and back are flat while its right and left sides have a convex shape (a semicircle or any other swollen shape), then it is impossible for the humidifier to lie with its left or right side on the ground (G). In that way finally the front (F) or the back (B) reaches safe and sound in contact with the ground (G) even though at first right or left side contacts with the ground (G). That is, the front (F) and back (B) are the lying sides.
  • the internal structure of the humidifying unit (200) is such that a partition is formed in perpendicular to the lying sides, water tank (210) and humidifying chamber (220) are divided by the partition, the vent (222) and blast pipe (350) are located approximately in the middle of both lying sides,
  • the location of the water- feeding hole (202) equipped in the partition (201) is at the lower part of a partition in the front view and at the spot in which the distance (h4) to a lying side (the back, B) is minimized in the plan view.
  • water level of the humidifying bath (221) has to be maintained at a certain level to be determined by the characteristic of the ultrasonic vibrator (301) in order that the size of the sprayed particle be constant and the spraying generation by the ultrasonic vibrator (301) be efficient.
  • the typical value of the resonant frequency of the ultrasonic vibrator popular in humidifiers is 1.65 MHz, in which case the optimum water level for spraying generation efficiency is 38 mm. If the water level is higher or lower than this, the spraying generation gets less efficient.
  • the water level of the humidifying bath (221) cannot be lowered too much in order to minimize amount of the water filled with the humidifying bath (221). Rather, humidifying bath (221) structure has to be able to minimize the amount of the water therein on condition that water level of the humidifying bath (221) is constant in the normal operating state.
  • Fig. 13 is the drawing showing that a water-obstructor (223) is equipped below the vent (222) as the means for preventing the water leaked in such situation.
  • Fig. 14 is the detail sectioned drawing of the vent (222) part for showing the operating principle of the water-obstructor (223). It shows the case in which the front side (F) of the humidifying unit (200) is in contact with the ground (G) when the humidifier tumbles down. At the moment that the external impact is applied and the humidifier tumbles down, the water of the humidifying bath (221) moves according to the leakage-preventing route (225) shown as an arrow in Fig. 14. It collides with the upper side of the humidifying unit (200), thereafter again collides with the water- obstructor (223). So, the direction of the water movement route is changed towards the humidifying bath (221). Therefore the water-obstructor (223) prevents the water leakage to the outside through the vent (222).
  • spraying nozzle (226) is combined with the vent (222) and seals the side cutouts (224) during the period the humidifier operates, it contributes to the prevention of leakage in case the humidifier tumbles down by the external impact. Therefore, the spraying nozzle (226) is not easily separated from the vent (222) though the external impact is applied. And the water-obstructor (223) can be long enough as much as its end reaches the location a little higher than the humidifying bath (221). It has the effect that the spray can be mixed well enough with the external air, in addition to the effect of the water leakage prevention. In this case, it is preferable that holes replace the side cutouts (224).
  • the horn (304) between the sound source (the spraying generator, more, accurately, the ultrasonic vibrator) and medium (the water of the humidifying bath) of the ultrasonic humidifier is necessary to have the horn (304) between the sound source (the spraying generator, more, accurately, the ultrasonic vibrator) and medium (the water of the humidifying bath) of the ultrasonic humidifier as the acoustically impedance matching means in order to raise the efficiency. And in the condition that maintains a constant water level of the humidifying bath (221), the horn (304) is helpful to minimize amount of the water filled into the humidifying bath (221).
  • Fig. 15 is an augmented drawing of the spraying generator (300) part of the ultrasonic humidifier of the prior art.
  • the humidifying bath (221) is integrated on the top of the base unit (100) with the base unit (100).
  • the horn (304) is attached to and under the humidifying bath by screwing together, generally using a few of the first screw.
  • the horn (304) is cast in the metal material with superior thermal conductance. The reason for this is that the power semiconductors used for the driver circuit of the ultrasonic vibrator (301) are attached to the horn (304) and cooled down. That is, the horn (304) also serves as the role of a heat sink.
  • the spraying generator (300) after diagonally inserting the ultrasonic vibrator (301) of the disc type into the inner circumference of the bushing (302) of the cylindrical shape being made of the elastic material including the rubber etc., the bushing is mounted inside of the housing (304) of the cylindrical shape. And the housing (303) is attached to the lower part of the horn (304) by screwing together using a few of the second screw.
  • the reason for diagonally inserting the ultrasonic vibrator (301) is to maintain the relatively smooth acoustically impedance matching in spite of the minute water level changing of the humidifying bath (221).
  • the spraying generator since the spraying generator is equipped in the base unit (100), said driver circuits directly supplies the electrical power to the ultrasonic vibrator (301) through the electric wire (103).
  • the spraying generator (300) of the present invention technology comprises as the followings. After diagonally inserting the ultrasonic vibrator (301) of the disc type into the inner circumference of the bushing (302) of the cylindrical shape being made of the elastic material including the rubber etc., a power receiver (311) is installed under the bushing (302) which receives high frequency alternating current from the base unit (100) and delivers the current to the ultrasonic vibrator (301). All of these are mounted inside of the housing (304) of the cylindrical shape.
  • the horn (304) is formed in a single body with the lower part of the humidifying chamber (220), a female screw (306) is formed on the inner circumference of the upper part of said housing (303), a male screw (305) is formed on the outer circumference of the bottom part of the said horn (304), so that the horn (304) and spraying generator (300) are combined water-tightly with the elasticity of the bushing (302), and acoustical impedance matching is achieved between the ultrasonic vibrator (301) and the water in the humidifying chamber (220), when said male screw (305) and female screw (306) unite.

Abstract

La présente invention concerne un humidificateur ultrasonique. Les humidificateurs ultrasoniques de l'état de la technique présentent l'inconvénient d'être très difficiles à nettoyer de sorte que les utilisateurs ne peuvent les nettoyer fréquemment. De sérieux problèmes de contamination se posent en raison de la prolifération de champignons et de bactéries lorsque des humidificateurs ultrasoniques sont utilisés pendant une période prolongée. Bien que différents moyens soient proposés pour résoudre ce problème, tels que l'injection d'antibiotiques et l'assainissement par chauffage de l'eau, leurs effets sont limités puisqu'ils entraînent des frais supplémentaires sans pour autant éliminer la cause de la contamination. L'objectif principal de l'invention est d'éradiquer la cause de contamination sans entraîner de frais supplémentaires en rendant les humidificateurs ultrasoniques faciles à nettoyer. A cet effet, l'humidificateur ultrasonique de l'invention comprend une unité d'humidification (200) qui est formée d'un simple corps et comprend un réservoir d'eau destiné à stocker de l'eau pour l'humidification, et une chambre d'humidification destinée à humidifier l'air extérieur, et une unité de base (100) qui fournit de l'électricité et de l'air extérieur à l'unité d'humidification lorsqu'une quantité d'eau suffisante est détectée pour l'humidification, l'unité d'humidification et l'unité de base pouvant être séparées, l'unité d'humidification présentant un orifice d'apport d'eau ou un canal d'apport d'eau situé dans la partie inférieure de la séparation entre le réservoir d'eau et la chambre d'humidification, et le réservoir d'eau présentant dans son fond un orifice d'entrée.
