  According to this configuration, the circular cross section of the ejection nozzle through which the atomized water passes is narrowed by the disk and the plurality of connecting portions, and the amount of large particle water directly ejected from the ejection port is reduced. Further, among the atomized water, those with large particles collide with the disk and aggregate, so the amount of water with large particles ejected from the ejection port is further reduced.

  A preferred embodiment of a humidifier according to the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view showing a humidifier according to the present invention. FIG. 2 is a sectional view showing the internal configuration of the humidifier according to the present invention.

  As shown in the perspective view of FIG. 1, the humidifier 1 has a vase-like appearance, and atomized water (hereinafter sometimes simply referred to as mist) is a spout 12 at the upper end of the humidifier 1. The air can be sprayed with air and the surroundings can be humidified.

  The humidifier 1 can be divided into an upper part and a lower part, and the housing 2 is also divided into a housing upper part 2a and a housing lower part 2b. The housing upper part 2a accommodates a water supply tank 3, an outlet 12 and the like, and the housing lower part 2b accommodates a water intake part 4, a mist forming part 5, a blower 6, a circuit part 8 and the like. The configuration and arrangement of each part will be described in detail below with reference to the drawings. FIG. 3 shows a perspective view in which the humidifier 1 is divided into upper and lower parts, and the upper part is viewed obliquely from below. FIG.

  The water supply tank 3 stores water for atomization and humidification. The water supply tank 3 is accommodated in the housing | casing upper part 2a, and the external shape of the water supply tank 3 is hemispherical. However, in order to send the water atomized by the mist formation part 5 to the upper jet outlet 12, the mist channel | path 3a has penetrated the center part of the water supply tank 3 in the orthogonal | vertical direction. Further, the water supply tank 3 is formed with a wind passage forming portion 9 to be described later. Note that water is supplied to the water supply tank 3 by opening the cap 3b of FIG.

  The water intake unit 4 is for taking water from the water supply tank 3. The water intake portion 4 is formed integrally with the lower substrate 20 and is a circular recess that is slightly larger than the cap 3b of the water supply tank 3 as shown in FIG. When the upper part and the lower part of the humidifier 1 are combined, the cap 3 b is inserted into the water intake part 4.

  The water intake unit 4 can take out water from the water supply tank 3 by a water supply mechanism provided in the cap 3 b of the water supply tank 3. An example of the water supply mechanism is one in which a water supply port 3c provided in the cap 3b is closed from the inside by a lid urged by a spring (not shown). The water intake 4 is exemplified by a protrusion (not shown) provided at a position facing the lid of the cap 3b at the bottom of a circular recess. According to this example, the water supply port 3c is normally closed from the inside by a lid urged by a spring, but when the upper and lower portions of the humidifier 1 are combined, the water intake 4 side has a protrusion. The lid is pushed into the interior, thereby opening the water supply port 3c, so that the water in the water supply tank 3 can be taken out from the water supply port 3c. However, the configuration of the water supply mechanism and the water intake unit 4 is not limited to this example.

  The mist formation part 5 is for atomizing the water taken out from the water supply tank 3 by the water intake part 4. The mist formation part 5 is comprised from the water storage part 5a which stores the water taken out from the water supply tank 3 in the water intake part 4, and the ultrasonic transducer | vibrator 5b attached to the bottom part of this water storage part 5a. The water reservoir 5a is formed integrally with the lower substrate 20.

  As shown in FIG. 4, the water storage part 5a is connected with the recessed part of the adjacent water intake part 4, and the water in the water intake part 4 can flow into the water storage part 5a. The ultrasonic vibrator 5b can atomize the water in the water storage section 5a by ultrasonic vibration, and a known one can be used as appropriate. Further, a water level sensor 5c for measuring the water level in the water storage unit 5a is provided in the water storage unit 5a, and when the water level becomes lower than a certain level, the vibration of the ultrasonic transducer 5b is automatically stopped. You may do it.

  The blower 6 is for spraying and diffusing the water atomized by the mist forming unit 5 together with the air from the outlet 12. The blower 6 is fixed to the lower surface of the lower substrate 20 and is accommodated in the housing lower part 2b. The air blower 6 can send the air taken in from the air hole provided in the bottom surface of the housing lower part 2b to the upper air blowing unit 7.

  As shown in FIG. 4, the air blower 7 is formed so as to protrude from the lower substrate 20, and the inside is hollow. The shape of the air blowing unit 7 is a square frustum in the figure, but may be other shapes such as a quadrangular column, a cylinder, and a truncated cone. The blower 6 is disposed below the blower unit 7 and can send air into the blower unit 7.

  The air sent into the blower unit 7 by the blower 6 is discharged from a blower port 7 a provided in the upper part of the blower unit 7. The air blowing port 7 a is a side wall of the air blowing unit 7 and is formed on a surface close to the mist forming unit 5. The air blowing port 7 a may be formed on the side wall of the air blowing unit 7 far from the mist forming unit 5, the upper surface of the air blowing unit 7, or the like. It is preferable to be provided in the upper part of the ventilation part 7 so that it may be difficult.

  When the upper part and the lower part of the humidifier 1 are combined, the air passage forming part 9 is formed in the water supply tank 3 so as to cover the blower part 7. Specifically, a rectangular concave portion that is slightly larger than the air blowing portion 7 of the square frustum is formed as the air passage forming portion 9.

  In FIG. 2, an enlarged cross-sectional view of the periphery of the air blowing part 7 and the air passage forming part 9 is shown in FIG. 5. The gap between the air passage forming portion 9 and the air blowing portion 7 serves as a passage for the air exiting from the air blowing port 7a. In the present embodiment, the air passage forming portion 9 An example in which the air passage 9a is formed by the gap between In this example, the side wall far from the mist forming part 5 of the blower part 7 is in contact with the air passage forming part 9 with almost no gap, and no air passage is formed on this side. Further, no air passage is formed between the side walls of the air blowing unit 7 in the direction perpendicular to the paper surface of FIG. 5 and the air passage forming unit 9. That is, only the gap between the side wall near the mist forming part 5 of the air blowing part 7 and the air passage forming part 9 functions as the air passage 9a.

  As shown by an arrow in FIG. 5, the air that has exited from the air blowing port 7 a is sent downward through the air passage 9 a, and then is sent to the upper portion of the mist forming unit 5 through the air vent 9 b. This sent air raises the water atomized by the mist formation part 5 to the mist channel | path 3a provided in the center of the water supply tank 3. FIG. The upper end of the mist passage 3a is connected to a pipe-like ejection nozzle 10 formed integrally with the housing upper part 2a. For this reason, the mist in the mist passage 3a is further raised in the ejection nozzle 10 by the flow of air, and finally sprayed from the ejection port 12.

  It is preferable that a suppression mechanism for suppressing the passage of fog as shown in FIG. 6 is provided in the ejection nozzle 10. FIG. 6 shows a view of the ejection nozzle 10 as viewed from the lower side, that is, the water supply tank 3 side. Specifically, in the suppression mechanism 11, a disk 11 a having a radius smaller than the circular cross section of the ejection nozzle 10 is coupled to the inner wall of the ejection nozzle 10 by a plurality of coupling portions 11 b. Note that the number of connecting portions 11b may be three as shown in FIG. 6A or four as shown in FIG. 6B.

  By forming the suppression mechanism 11 in the ejection nozzle 10, the section of the ejection nozzle 10 is narrowed by the disk 11a and the plurality of connecting portions 11b, and the atomized water is ejected with large particles. The amount directly ejected from the mouth 12 is reduced. Moreover, since the large particles of atomized water collide with the disk 11a and agglomerate, the amount of large particle water ejected from the ejection port 12 is further reduced. Thereby, it is possible to prevent water having large particles from being sprayed from the ejection port 12 and soaking the surroundings of the humidifier 1.

  Further, the casing lower part 2b accommodates a circuit unit 8 including a control circuit for controlling the ultrasonic transducer 5b and the blower 6. The circuit unit 8 turns on / off the ultrasonic vibrator 5b and the blower 6 by an on / off signal from a switch (not shown), or automatically turns the ultrasonic vibrator 5b and the blower 6 on by the signal of the water level sensor 5c described above. Or turn it off.
