  In such a conventional humidifier, water is evaporated in a state where water is once stored in the water storage container or moisture absorbent body. Therefore, in the long-term use, scale is generated inside the water storage container and adheres to the stored water. In the system in which water droplets 102 are dropped on the electric heating element 101 disposed on the inner bottom portion of the container 100, the water droplets 102 come into contact with the electric heating element 101 and the moisture evaporates. Precipitation of scale due to problems such as accumulation of moisture content and dust in the air at the contact portion of the water droplet 102, which tends to be unsanitary and requires regular cleaning in terms of hygiene, which requires troublesome management. There is also a need for a hygienic and humidifying method that suppresses the accumulation of moisture and dirt and dust.

  In addition, in the method of heating and evaporating the water droplet 102 being dropped by the spiral state electric heater 106, the water droplet 102 needs to evaporate while passing through the spiral state electric heater 106, so the helical state electric body 106 is heated to a high temperature. Therefore, there is a problem that a large amount of electric power is required for humidification, and a method capable of performing humidification with low power consumption is required.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIGS. 1 and 2, a water supply tank 2 for storing humidifying water is provided inside a hollow device housing 1, and a water supply pipe for guiding water inside the water supply tank 2 to the lower part of the water supply tank 2. 3, the water pipe 3 is connected to the water feeding means 4 for feeding out water, and the water fed from the water feeding means 4 is arranged by disposing the nozzle 5 with the tip facing upward in the water feeding direction of the water feeding means 4. A polka dot 6 is formed by being pushed out to the tip of the nozzle 5. A heating means 7 for heating and evaporating the formed polka dots 6 is disposed at the tip of the nozzle 5. Here, since the water supply means 4 is disposed below the water supply tank 2, the water in the water supply tank 2 is pressurized under the influence of gravity and constantly flows toward the water supply means 4.

  Further, the water supply means 4 and the heating means 7 are connected to a humidification control means 8 for controlling the timing of forming the polka dots 6 on the tip of the nozzle 5 by the water supply operation and the timing of the heating operation of the heating means 7 for heating the formed polka dots 6. Is done. A water tray 9 for receiving the water dripped by mistake is disposed below the nozzle 5. Blower means 10 that blows air inside the apparatus housing 1 upward is disposed below the water tray 9, and outside air is blown by the air blower 10 at the upper and lower ends of the apparatus casing 1. Air blowing openings 11a and 11b are provided so that air can be sucked into the interior of the apparatus 1 and discharged outside the apparatus housing 1. A confirmation window 12 is provided at a position where the heating means 7 is disposed inside the surface of the apparatus housing 1 and at a position where the polka dots 6 formed on the nozzle 5 heated by the heating means 7 from the outside of the apparatus housing 1 can be seen. Is arranged.

  Here, the humidification control means 8 has its main function constituted by the microcomputer 13, and controls the timing of the water supply operation of the water supply means 4 to be controlled and the timing of the heating operation of the heating means 7 in time series. As shown in the flow chart of FIG. 3, after supplying a water supply signal to the water supply means 4 in step Sa1, wait for a certain waiting time in step Sa2 to wait for normal formation of the polka dots 6 and then heat in step Sa3 after the waiting time has elapsed. Humidification is performed by heating and evaporating the polka dots 6 by giving a heating signal to the means 7 for a certain period of time, and the humidification operation is controlled by defining the repetition of this series of operations by software. . The waiting time in step Sa2 is to set an optimum value from the actual confirmation result until the polka dots 6 are completely formed by the activation of the water supply means 4, and the transmission time of the heating signal to the heating means 7 in step Sa3 is The shortest time required for heating and evaporating the polka dots 6 on which the target heating means 7 is formed is confirmed by testing and set. The microcomputer 13 is a so-called one-chip microcomputer incorporating a central processing unit (CPU), an input / output device, an analog / digital conversion input device (A / D), a read only memory (ROM), and a read / write memory (RAM). It is.

  Next, the structure of the water supply means 4 is demonstrated based on FIG.

  The water supply means 4 includes a water supply side water passage 20 that communicates with the water supply pipe 3, a pressure water passage 21 that applies pressure to the supplied water, and a nozzle water passage 22 that discharges the pressurized water. The nozzle 5 is configured. The water supply side water channel 20 and the pressurized water channel 21 are separated by a ball valve 24 that is operatively held in the water channel and a ball valve seat 25 provided on the water supply side water channel 20 side that contacts the ball valve 24 to close the water channel. The ball valve 24 is regulated by a ball valve stop rod 26 so as not to move in the direction of the pressurized water passage 21. A movable plunger 27 that is press-fitted into the pressurized water channel 21 and applies pressure to the water in the pressurized water channel 21 is disposed in the pressurized water channel 21, and this plunger 27 is driven by an electromagnetic actuator 28. The plunger 27 is provided with a plunger valve 29 that separates the pressurized water passage 21 and the nozzle water passage 22. The plunger valve 29 is inserted into the pressurized water passage 21 in the plunger valve 29 with the pressurized water passage 21 and the nozzle water passage 22. Plunger port 30 for conducting is arranged.

  Here, the electromagnetic actuator 28 is normally in a contracted state, and is configured to protrude when receiving a water supply signal from the microcomputer 13. For example, the power of the power supply power source is a transistor or the like. The general switching element is configured to close the power supply signal as a trigger to supply electric power to the electromagnetic actuator 28 and drive it to project.

  Next, the operation of the water supply means 4 configured as described above will be described.

  As described above, the water in the water supply side water channel 20 is constantly pressurized by gravity, and the ball valve 24 receives a force pushed by the ball stopper rod 26 in the direction of the pressurized water channel 21 due to the pressurization of the gravity. The water channel 20 and the pressurized water channel 21 are normally in a conductive state. In addition, the plunger 27 is normally held in a state where the pressurized water passage 21 is opened. Therefore, the plunger valve 29 configured in the plunger 27 separates the pressurized water passage 21 and the nozzle water passage 22, and in a steady state. The water in the pressurized water passage 21 is stopped by the plunger valve 29 so that it does not leak in the direction of the nozzle water passage 22. Here, when the electromagnetic actuator 28 operates in response to the water supply start signal 14 from the microcomputer 13, the plunger 27 is pushed out in the direction of the pressurized water channel 21, so that the water inside the pressurized water channel 21 is pressurized. When the water inside the pressurized water passage 21 is pressurized, the ball valve 24 is pressed against the ball valve seat 25 by this pressure, and the water supply side water passage 20 and the pressurized water passage 21 are brought into contact with the ball valve seat 25 by pressure. 24. In a state where the water supply side water channel 20 and the pressurized water channel 21 are separated, when the plunger 27 is further pushed into the pressurized water channel 21, the pressure in the pressurized water channel 21 increases and the plunger provided in the plunger valve 29. When the plunger 27 moves to a position where the opening 30 is connected to the pressurized water passage 21 and the nozzle water passage 22, the pressurized water in the pressurized water passage 21 flows out through the plunger mouth 30 in the direction of the nozzle water passage 22. The polka dots 6 are formed at the tip of the end 23. FIG. 5 shows the operating condition of the water supply means 4 when the polka dots 6 are formed.

  In the state where the plunger 27 is completely pushed out into the pressurized water channel 21, the pressurized water channel 21 and the nozzle water channel 22 are separated by the plunger 27, so that the water pressurized from the water supply side water channel 20 side is the nozzle water channel. It will not leak in the direction of 22. When the water supply start signal 14 from the microcomputer 13 stops and the electromagnetic actuator 28 returns to the steady state position, the plunger 27 opens the pressurized water passage 21 and simultaneously the plunger valve 29 separates the pressurized water passage 21 and the nozzle water passage 22 and stops. Since water is lost, the flow of water in the direction of the nozzle end 23 is stopped, and the polka dots 6 formed on the nozzle end 23 are held without dripping.

  Here, the volume of the pressurized water passage 21, the volume of the plunger 27, and the arrangement position and the hole diameter of the plunger port 30 arranged on the plunger valve 29 are such that the polka dots 6 formed at the nozzle end 23 maintain the surface tension. It is set so as to have a volume containing water that does not dripping and that can realize a target humidification amount by one water feeding operation.

  Needless to say, the nozzle end 23 is made of a highly water-repellent material such as Teflon (registered trademark) or coated to increase the contact angle with water and form and hold the polka dots 6 more stably. .

  Further, as shown in FIGS. 6 to 8, the presence of the polka dots 6 formed at the tip of the nozzle 5 is detected at the position where the polka dots 6 at the tip of the nozzle 5 are formed, and the presence or absence of the polka dots 6 is detected with respect to the humidification control means 8. A polka dot sensing means 40 for sending information is arranged, and a water leak sensing means 41 for sensing the dripping of the polka dots 6 and notifying the humidification control means 8 of the occurrence of water leakage is arranged at the lower part of the nozzle 5 to detect the polka dots. When the means 40 senses the formation of the polka dots 6, the heating means 7 heats the polka dots 6, and when the water leakage sensing means 41 senses the occurrence of water leakage, the humidification control means 8 stops the humidification operation. A judgment operation can also be set.

  Here, the water leak detection means 41 is disposed inside the water tray 9, and a dish lid 42 is disposed on the water tray 9, and the dish lid 42 has a funnel-like shape for collecting the dropped water. By providing the water collecting port 43 and disposing the water leak detecting means 41 immediately below the center of the water collecting port 43, the water leak detecting means 41 can reliably detect the dropped water.

  Next, the configuration of the polka dot sensing means 40 and the water leak sensing means 41 will be described with reference to FIG.

  The polka dot detection means 40 and the water leak detection means 41 are configured in the same manner, and the light emitting diode 44 and the NPN phototransistor 45 that receives light emitted from the light emitting diode 44 and is in a conductive state are opened in a certain space. It is composed of a general photo interrupter circuit arranged and constructed. Here, the light-emitting diode 44 is connected to a circuit power supply 46 serving as a power supply source through a resistor a47a to emit light by applying power, and the NPN phototransistor 45 is similarly connected to the circuit power supply 46 through a resistor b47b. Power is applied, and a connection point between the NPN phototransistor 45 and the resistor b47b is used as a sensing voltage output terminal.

  In this configuration, if there is no obstruction in the space between the light emitting diode 44 and the NPN phototransistor 45, the light emitted from the light emitting diode 44 reaches the NPN phototransistor 45 and the NPN phototransistor 45 is in a conductive state. The output terminal 48 is almost at the GND voltage, and if there is an obstacle in the space between the light emitting diode 44 and the NPN phototransistor 45, the light emitted from the light emitting diode 44 does not reach the NPN phototransistor 45. The same voltage as the circuit power supply 46 is output.

  Therefore, if the output voltage of the sensing voltage output terminal 48 is the GND voltage, it can be determined that there is no object that obstructs the space between the light emitting diode 44 and the NPN phototransistor 45, and is the same as the circuit power supply 46. If it is about a level, it can be determined that there is a sensing state where there is an obstacle. The object that blocks the space between the light emitting diode 44 and the NPN phototransistor 45 is the polka dot 6 in the case of application to the polka dot detection means 40, and the dropped water in the application to the water leak detection means 41. In the case of application, the light emitting diode 44 and the NPN phototransistor 45 are arranged with a space in the arrangement where the polka dots 6 are located in the center of the light emitting diode 44 and the NPN phototransistor 45, and applied to the water leak detection means 41. In this case, the light emitting diode 44 and the NPN phototransistor 45 are arranged at a distance from each other at a position where water dropped from the center of the light emitting diode 44 and the NPN phototransistor 45 passes.

  Each detection result of the polka dot detection means 40 and the water leak detection means 41 is input to the microcomputer 13 constituting the humidification control means 8 as a signal of a voltage change at its detection voltage output terminal 48, and the microcomputer 13 receives this input. The humidification operation of the humidification control means 8 is changed by judging the presence of the polka dots 6 and the occurrence of water leakage from the voltage change signal.

  Next, the correspondence between the detection result of the polka dots 6 of the polka dot detection means 40 and the humidification operation determined by the microcomputer 13 constituting the humidification control means 8 will be described with reference to the flowchart of FIG.

  The flowchart shows a routine after the water supply operation is performed by starting the water supply means 4 in step Sb1, and the detection result of the polka dots 6 of the polka dot detection means 40 is determined in step Sb2. If the result of determination in step Sb2 is that the polka dot 6 is in the sensing state, the heating means 7 is activated in step Sb3 to heat the polka dot 6, and thereafter, a series of control routines are repeated. In addition, if the polka dot 6 is in a non-sensing state based on the determination result in step Sb2, it is determined that the polka dot 6 is not formed. Therefore, the detection determination of the polka dot 6 in step Sb2 is performed again after a predetermined time has elapsed in step Sb4. Let Note that the number of passages is counted in step Sb4, and if there is a certain number of passages in step Sb4, it is possible to determine a failure due to the destruction of the water supply means 4 and stop a series of humidification operations.

  Next, the correspondence between the detection result of the occurrence of water leak of the water leak detecting means 41 and the humidifying operation determined by the microcomputer 13 constituting the humidifying control means 8 will be described with reference to the flowchart of FIG.

  The flowchart shows a routine after execution of the water supply operation by starting the water supply means 4 in step Sb1, and the detection result of the water leak state of the water leak detection means 41 is determined in step Sc2. If there is no water leak as a result of the determination in step Sc2, the heating means 7 is activated in step Sb3 to heat the polka dots 6 to perform humidification. Thereafter, the humidification operation is executed by repeating a series of control routines. Will be. Further, if it is determined that the water leak has occurred according to the determination result in step Sc2, a series of humidification control operations are stopped in step Sc3 since it is determined that water has dripped. In addition, when the humidification control operation is stopped in step Sc3, the function of improving the maintainability by notifying the user of the stop of the humidification operation due to the occurrence of water leakage by notifying by the generation of light or sound of the lamp. Needless to say, you can offer.

  Next, the structure of the heating means 7 will be described with reference to FIGS.

  Here, the electric heating element 50b uses a ceramic type or the like which has a high insulating property and uses a short-time heat generation type electric heater, and generates heat by supplying power when receiving a heating signal from the humidification control means 8. is there. Further, the outlet 55 is set to have a hole diameter that matches the diameter of the polka dots 6 formed on the nozzle 5, and is further arranged close to the polka dots 6, and the blowing air speed of the thermal blower 53 is from the outlet 55. By setting the wind speed to such an extent that the polka dots 6 are not blown away without being evaporated by the hot air blown out, the heat generated by the electric heating element 50b is concentrated only on the polka dots 6 and sprayed to efficiently heat the polka dots 6. And evaporate.

  As shown in FIG. 15, the heating means 7 includes a high heat generation lamp 57 inside the lamp shell 56, and the light emitted from the high heat generation lamp 57 is formed on the nozzle 5 once in the lamp shell 56. A lens 58 for focusing and irradiating the polka dots 6 is disposed. Here, the high exothermic lamp 57 uses a halogen type electric lamp or the like that emits a large amount of infrared rays having a wavelength of 0.8 to 5 μm, which has the highest heating action. The polka dots 6 can be efficiently emitted by selecting the one that can irradiate with sufficient infrared rays to instantaneously heat and evaporate the polka dots 6 when the light is concentrated and irradiated on the polka dots 6 with the lens 58.
