(First embodiment)
Hereinafter, a first embodiment in which the present invention is applied to a vehicle humidifier used for humidifying a vehicle interior will be described with reference to FIGS. 1, 2, and 3. FIG. 1 is a diagram illustrating an internal structure of a vehicle humidifier according to the present embodiment. FIG. 2 is a partially enlarged view showing the heating device in the present embodiment. FIG. 3 is a diagram illustrating a mounting state of the vehicle humidifier in the vehicle interior according to the present embodiment, and shows the positional relationship among the vehicle humidifier 100, the passenger 200, the handle 300, and the seat 400. Note that the direction in the present embodiment is the direction when the vehicle humidifier is installed in the vehicle.

  The vehicle humidifier 1 includes a resin casing 2. The casing 2 is assumed to be provided on the ceiling surface in the vehicle compartment, and includes an upper bottom surface facing the ceiling surface in the vehicle interior and a lower bottom surface facing the passenger's head. Moreover, the inside of the casing 2 is formed with a humidifying section 2a that houses a humidifying mechanism that will be described later, and an air blowing section 2b that houses a blowing mechanism that will be described later. And the division wall 2c which divides | segments both divisions is provided between the humidification division 2a and the ventilation division 2b. Furthermore, a heat insulating member 2 d having a heat transfer coefficient lower than that of the material constituting the casing 2 covers the outer wall of the casing 2.

  Next, the configuration of the humidifying mechanism housed in the humidifying section 2a will be described. First, the partition wall 2c is provided with an air intake 3 for taking in air from the outside of the humidifying compartment 2a to the inside of the humidifying compartment 2a. In addition, the air intake 3 takes in air from the outside of the casing 2 and a permeable membrane 4 having a porous structure with a predetermined pore diameter, which is also a dew condensation part, connects the air intake 3 from the air blowing section 2b side. It is assembled to cover. In this embodiment, a permeable membrane having a porous structure with a pore diameter of 0.45 μm is used. Thereby, it can suppress that foreign materials, such as bacteria and dust larger than 0.45 micrometer, permeate the inside of the humidification division 2a. In this embodiment, the dew condensation part is formed by the permeable membrane 4.

  An electric heater 5 that generates heat when a voltage is applied is assembled to the side facing the air intake 3 in the humidifying section 2a. And the radiation fin 6 provided with the fin part 6b formed in the some convex shape is provided in the upper surface in the installation direction of the casing 2 of the electric heater 5. As shown in FIG. The radiating fin 6 is preferably formed of a material having excellent corrosion resistance, and for example, stainless steel (SUS304) may be used.

  Near the central portion of the humidifying compartment 2a, a columnar member 2e that is inscribed in the upper and lower bottom surfaces of the casing 2 and that forms a path through which air circulates in the humidifying compartment 2a is provided. Further, the columnar member 2e is chamfered at the corners so as not to hinder the air flow generated inside the casing 2.

  As shown in FIG. 2, the heat radiating fin 6 includes a plurality of fin portions 6 b that are convex portions and a groove portion 6 a that is a concave portion formed between adjacent fin portions 6 b. The heat radiating fins 6 are installed in the humidifying section 2a in such a direction that the fin portions 6b follow the air flow generated inside the casing 2.

  The surface of the fin portion 6b of the radiating fin 6 is coated with a water absorbing material 7 that absorbs moisture contained in the contacting air and releases it into the contacting air when heated. In the present embodiment, 50 g of silica gel is used as the water absorbing material 7. This silica gel is obtained by dehydrating and drying a silicate gel obtained by hydrolyzing an acid component generated by leaving an aqueous solution of sodium metasilicate. Therefore, it is possible to fix the silica gel in a state before dehydration / drying to the surface of the fin portion 6b by applying the silica gel to the surface of the fin portion 6b and drying it.

  Below the permeable membrane 4, a water collection portion 8 is formed that expands downward from the bottom surface of the casing 2 so that water converges in one place. In addition, when the vehicle performs a turning motion or the like between the electric heater 5 and the water collecting unit 8, the water collected in the water collecting unit 8 is inhibited from being approached to the electric heater 5. Members 9a and 9b are formed. When viewed from the water collecting portion 8 side, the obstructing members 9a and 9b are gently raised upward from the lower bottom surface of the casing 2, and are gently lowered at the apex to coincide with the lower bottom surface of the casing 2. It is formed in a chevron shape.

  A water retention member 14, which is a cylindrical sponge capable of absorbing moisture, is assembled at the lowermost part of the water collecting portion 8. An ultrasonic vibrator 15 and an ultrasonic oscillator 16 that vibrates the ultrasonic vibrator 15 at a predetermined frequency are assembled on the lower end side of the water retaining member 14. A portion of the ultrasonic vibrator 15 that contacts the water retention member 14 is provided with a plurality of through holes. When the ultrasonic vibrator 15 vibrates, the moisture contained in the water retention member 14 is fogged. It becomes. In addition, since the ultrasonic transducer | vibrator 15 is used in the environment exposed to the water | moisture content, it is preferable to form with the material excellent in corrosion resistance, for example, it is good to use stainless steel (SUS304).

  Each corner portion present in the humidifying section 2a is processed so that the inner surface of the corner portion is a gently curved surface. Thereby, it can reduce that water stays at a corner | angular part by interfacial tension.

  Next, the configuration of the air blowing section 2b will be described. The blower section 2b has a suction port (not shown) that sucks air from the outside of the casing 2, and a dew condensation section blower 10 that is an axial fan that sucks air from the suction port and generates an air flow in the longitudinal direction of the blower section 2b. Is provided. In this embodiment, since the permeable membrane 4 also serves as a dew condensation part, the orientation of the dew condensation part blower 10 is adjusted so that the air flow generated in the dew condensation part blower 10 is directed to the permeable film 4. .

  On the downstream side of the air flow of the dew condensation unit blower 10, a driven fan 11 that is rotated by receiving the air flow from the dew condensation unit blower 10 is installed. And the magnetic coupling 12 which transmits rotation of the driven fan 11 to the inside of the humidification division 2a using magnetic force across the division wall 2c is assembled | attached to the division wall 2c.

  Inside the humidifying section 2a, a casing internal blower 13 that is rotated by the rotational power transmitted by the magnetic coupling 12 and generates an air flow circulating inside the humidifying section 2a is installed. The casing internal blower 13 is a centrifugal fan through which fluid passes through the impeller in the radial direction.

  Next, the operation mode of the vehicle humidifier in this embodiment will be described. In the humidifying device for a vehicle in the present embodiment, the moisture contained in the air taken from the outside is absorbed, and after being vaporized, the water is obtained by dew condensation, and the purification is performed in the humidified water purification mode. And a humidifying mode for humidifying the sprayed water by spraying the atomized water into the vehicle compartment. Moreover, the vehicle humidifier 1 includes a mode change switch (not shown) that can switch between the humidified water purification mode and the humidified mode. Below, both operation modes are demonstrated concretely.

  First, the operation content in the humidified water purification mode will be described.

  When the humidification water purification mode is turned on by the mode switch, the dew condensation section blower 10 and the electric heater 5 are turned off. At this time, air containing moisture flows into the humidifying compartment 2a through the permeable membrane 4. This is because the inside of the humidifying compartment 2a is in a state where the humidity is lower than the outside of the humidifying compartment 2a due to the water absorption action of the water absorbing material 7, and water molecules contained in the high humidity air outside the humidifying compartment 2a tend to diffuse. This is because it flows into the humidifying section 2a having a lower humidity.

  Moisture that has flowed into the humidification compartment 2 a through the permeable membrane 4 is absorbed by the water absorbing material 7. And as long as the water absorbing material 7 absorbs water, the humidity inside the humidifying section 2a is lower than the outside of the humidifying section 2a. Therefore, air containing moisture flows into the humidifying section 2a through the permeable membrane 4 until the amount of water stored in the water absorbing material 7 reaches a limit. When the predetermined time necessary for the water absorbing material 7 to sufficiently absorb water elapses in the timer circuit (not shown), the vehicle humidifier 1 proceeds to the next step.

  When a predetermined time necessary for the water absorbing material 7 to sufficiently absorb water elapses, a timer circuit (not shown) provided in the vehicle humidifier 1 turns on the electric heater 5. Thereby, first, the surface temperature of the electric heater 5 rises. And with the temperature rise of the electric heater 5, the temperature of the radiation fin 6 also rises. As the temperature of the radiating fin 6 rises, the temperature of the water absorbing material 7 applied to the surface of the radiating fin 6 also rises. As the temperature of the water absorbing material 7 rises, the water stored in the water absorbing material 7 is released into the air in the humidifying section 2a. In the present embodiment, silica gel is used as the water-absorbing material 7, and the temperature at which the silica gel releases water is generally 100 ° C. to 200 ° C. Therefore, in this embodiment, it controls using the thermostat which is not shown in figure so that the surface temperature of the radiation fin 6 heated with the electric heater 5 may be about 120 degreeC.

  When moisture is released from the water absorbing material 7, the inside of the humidifying section 2a is in a humid state compared to the outside of the humidifying section 2a. Moreover, since heat is dissipated by the electric heater 5 inside the humidifying compartment 2a, the inside of the humidifying compartment 2a is in a higher temperature state than the outside of the humidifying compartment 2a.

  When a predetermined time determined by the temperature rise specification of the electric heater 5 and the characteristics of the water absorbing material 7 elapses, a timer circuit (not shown) turns on the dew condensation fan 10.

  When the dew condensation part blower 10 operates, the side surface of the blower section 2b of the permeable membrane 4 is air-cooled, and the temperature is lowered. As a result, the air in the humidification section 2a heated by the electric heater 5 and containing moisture moves toward the permeable membrane 4 having a lower temperature.

  Here, in this embodiment, the permeable membrane 4 is provided so that the center of gravity of the permeable membrane 4 which is also a dew condensation portion where moisture is condensed is positioned above the center of gravity of the humidifying section 2a in the gravity direction. As shown in FIG. 3, the casing 2 is tilted by an angle c in the vehicle compartment so that the center of gravity b of the permeable membrane 4 is positioned above the center of gravity a of the humidifying section 2a in the direction of gravity. is set up.

  As a result, the air containing water that has been heated by the electric heater 5 moves toward the permeable membrane 4 having a lower temperature, is cooled by the permeable membrane 4, and the surface of the permeable membrane 4 on the humidifying section 2a side is cooled. Allow condensation. The air cooled by the permeable membrane 4 is lowered by gravity. Due to the movement of the air, a heat convection 100 as shown in FIG. 1 is generated inside the humidifying section 2a.

  Further, the driven fan 11 is rotated by the air flow generated by the dew condensation unit blower 10. As the driven fan 11 rotates, the casing internal blower 13 connected to the driven fan 11 via the magnetic coupling 12 rotates. And the thermal convection which generate | occur | produces inside the humidification division 2a can be further accelerated | stimulated by rotating the internal fan 13 of a casing.

  The hot and humid air circulating inside the humidifying compartment 2a by the heat convection 100 generated inside the humidifying compartment 2a contacts the permeable membrane 4 existing on the circulation path. At this time, the air blowing section 2b side surface of the permeable membrane 4 has a lower temperature than the humidifying section 2a. Further, even when the permeable membrane 4 is heated by contact with high-temperature and high-humidity air circulating inside the humidifying compartment 2a by the thermal convection 100, the permeable membrane 4 from the outside of the humidifying compartment 2a by the air flow by the dew condensation section blower 10 Can be radiated, and the permeable membrane 4 can be kept at a temperature lower than that of the humidifying section 2a. In this way, when the high-temperature and high-humidity air comes into contact with the side surface of the humidifying section 2a of the permeable membrane 4 having a temperature lower than that of the humidifying section 2a, moisture is condensed and condensed.

  The water molecules on the surface of the water droplets condensed on the permeable membrane 4 are subjected to van der Waals force from the water molecules inside the water droplets. However, the force that the water molecules on the surface of the water drop receive from the air molecules present in the humidifying section 2a is extremely small as compared with the van der Waals force described above. That is, the water molecules on the surface of the water droplet are always pulled only from the water molecules inside the water droplet. Thereby, on the surface of the permeable membrane 4, the water droplets having a certain size or more are unbalanced between the gravity from the earth and the interfacial tension, which is the force pulled from the inside of the water droplets, and fall in the weight direction. .

  Water droplets that have fallen from the surface of the permeable membrane 4 converge to the water collecting unit 8 that is installed below the permeable membrane 4 on the humidifying section 2a side. Furthermore, in this embodiment, a highly water-repellent paint is applied to the inner surface of the humidifying section 2a. Thereby, the convergence of the water to the water collection part 8 can be accelerated | stimulated.

  As described above, when the humidified water purification mode is executed, moisture is collected in the water collection unit 8.

  Next, a description will be given of a humidification mode in which humidification is performed by jetting atomized water into the vehicle interior using water purified in the humidification water purification mode.

  When the humidification mode is turned on by the mode switch, a voltage is applied to the ultrasonic oscillator 16. Then, the ultrasonic oscillator 16 vibrates the ultrasonic vibrator 15 mechanically coupled to the ultrasonic oscillator 16 at a predetermined frequency. In the present embodiment, the oscillation frequency of the ultrasonic oscillator 16 is set to 2.4 MHz.

  The ultrasonic transducer 15 is provided with a large number of minute through holes having a predetermined hole diameter. When this ultrasonic vibrator vibrates in contact with the water retaining member 14 containing water, minute polka dots are generated in the respective through holes. Water can be atomized by generating a large number of these minute polka dots.

  The water atomized by the ultrasonic vibrator 15 passes through a spray port (not shown) provided in the lower part of the casing 2 and diffuses into the vehicle compartment by gravity acceleration acting downward due to gravity and a substance diffusion action. To do. Thereby, the air in the vehicle compartment is humidified.

  In the present embodiment, moisture contained in air taken from the vehicle interior is absorbed using a water absorbing material, water is released by heating the absorbed water absorbing material, and water is obtained by condensing the released moisture. An example of humidification using the water was introduced. Thereby, the humidification apparatus which reduced the necessity of the water supply by a human hand can be provided.

  In the present embodiment, a permeable membrane 4 is provided at the air intake 3. Thereby, it can suppress that foreign materials, such as bacteria and dust larger than the hole diameter of the permeable membrane 4, permeate into the humidification division 2a. Therefore, it is possible to reduce the propagation of bacteria in the humidifying section 2a and the malfunction of the ultrasonic vibrator 15 due to the invading foreign matter.

  Further, in the present embodiment, a casing internal blower 13 that generates an air flow in the humidifying compartment 2a and a columnar member 2e that constitutes a route circulating in the humidifying compartment 2a are provided. Thereby, generation | occurrence | production of the heat convection in the humidification division 2a is accelerated | stimulated, more water can be condensed and more water can be obtained.

  In addition, in the present embodiment, inhibition members 9 a and 9 b are formed to inhibit water collected in the water collection unit 8 from approaching the electric heater 5. Thereby, since the obtained water is inhibited from flowing to the electric heater 5, it can be prevented from evaporating again by the electric heater 5. The obstructing members 9a and 9b are gently raised upward from the lower bottom surface of the casing 2 when viewed from the water collecting portion 8 side, and the height gradually decreases at the apex. It is formed in a mountain shape having the same height. Therefore, it is possible to reduce the inhibition of the heat convection 100 generated in the humidification section 2a by the inhibition members 9a and 9b.

  And each corner | angular part which exists in the humidification division 2a is processed so that a corner | angular part inner surface may become a gentle curved surface, in order to prevent that water stays in a corner | angular part by interface tension. Thereby, since more water collects in the water collection part 8, more water can be used for humidification.
