Description

  The present invention relates to a fluid conveyance device.

  In the fluid conveyance device, the high-humidity air generation unit generates high-humidity air. The high-humidity air is conveyed to the pressurizing chamber using a pipe or a blower. The humid air is discharged from the pressurizing chamber as a vortex ring (see, for example, Patent Documents 1 and 2).

  However, in these fluid conveyance devices, the product size is increased by the amount of the piping and the blower fan.

  On the other hand, a fluid conveyance device having a high-humidity air generation unit in a pressurized chamber has been proposed. According to the fluid conveyance device, the pressurized chamber can be filled with high-humidity air without using a pipe or a blower fan (see, for example, Patent Document 3).

Japanese Patent No. 3675203 JP 2010-054146 A Japanese Patent No. 4559498

  However, in the fluid conveyance device, the pressurizing chamber becomes larger by the amount of the high-humidity air generation unit. For this reason, the pressurized chamber cannot be filled with high-concentration high-humidity air. Moreover, if the excitation force for the high-humidity air is insufficient, only a small vortex ring with insufficient transport distance and water retention amount is released. That is, in order to discharge a high-density vortex ring with a large amount of water retention, a large vibrator is required. For this reason, the fluid conveyance device becomes large and heavy.

  This invention was made in order to solve the above-mentioned subject, and the objective is to provide the fluid conveying apparatus which can discharge | release a high-density vortex ring, even if a product size is small.

Fluid transport apparatus according to the present invention includes a fluid reservoir which is provided so as to store the fluid, vaporized or atomized allowed by the fluid storage to produce a high-humidity air of the stored fluid in the fluid reservoir and high-humidity air generating part provided in parts, so as to extend in one direction from immediately above the fluid reservoir to hold the high-humidity air generated in the high-humidity air generating part in the horizontal direction of the fluid reservoir A high-humidity air storage section provided, and a pressurization chamber provided directly above the high-humidity air storage section and having an opening communicating with the high-humidity air storage section on one side in the horizontal direction of the fluid storage section A vibration unit provided to pressurize the high-humidity air retained in the high-humidity air storage unit by vibrating in the vertical direction in the pressurization chamber; and the high-humidity air pressurized by the vibration unit the pressure chamber but to be released in the horizontal direction becomes vortex ring The said fluid reservoir of said high-humidity air reservoir is obtained and a vortex ring generator communicating with the opposite side just below.

  According to the present invention, a high-density vortex ring can be released even if the product size is small.

  An atomization chamber 10 is provided immediately above the water storage unit 5 as a high-humidity air storage unit. The atomization chamber 10 is formed so as to protrude from the water storage unit 5 toward the center of the main body case 1. An inclined surface 10 a is formed on the center side of the main body case 1 at the bottom of the atomizing chamber 10. The inclined surface 10 a is inclined downward from the central side of the main body case 1 with respect to the water reservoir 5. The lower edge portion of the inclined surface 10 a is connected to the central side of the main body case 1 at the upper edge portion of the water storage portion 5.

  A pressurizing chamber 11 is provided immediately above the atomizing chamber 10. In the center of the lower surface of the pressurizing chamber 11, an opening 11a is provided.

  A vibration exciter 12 is provided directly above the pressurizing chamber 11 as a pressurizing unit. The vibrator 12 has the same structure as a general speaker. That is, the vibrator 12 includes a voice coil 12a, a diaphragm 12b, and a magnet 12c.

  The voice coil 12a is disposed on the vertical line at the approximate center of the opening 11a. A diaphragm 12b as a vibrating part is fixed to a fixed position below the voice coil 12a through an adhesive layer. The diaphragm 12b is formed of a material having heat resistance. The lower surface of the diaphragm 12b is formed to be larger than the area of the opening 11a on the horizontal projection surface.

An input end of the ultrasonic element 9 is connected to the control device 14. The control device 14 is connected to the input end of the voice coil 12a.

Next, operation | movement of a fluid conveying apparatus is demonstrated using FIG.
FIG. 3 is a flowchart for explaining the operation of the fluid conveyance device according to Embodiment 1 of the present invention.

  First, water is supplied to the water supply tank 2 outside the main body case 1. Thereafter, the water supply tank 2 is inserted into the main body case 1 along a tank insertion portion (not shown). By the insertion, the water in the water supply tank 2 flows into the water supply unit 3 through the water supply valve 2a. The water flows into the water reservoir 5 through the water supply channel 4. At this time, the amount of water supplied from the water supply tank 2 is kept constant by the water supply valve 2a. As a result, the water reservoir 5 is filled with water up to the same height as the upper end of the heater 7.

  Thereafter, when a power source SW (not shown) is pressed in step S1, the power source of the fluid conveyance device is turned on. With this state, the operation of the fluid conveyance device is started. Then, it progresses to step S2 and the control apparatus 14 makes the heater 7 an ON state. In this state, a current flows through the heater 7. The heater 7 generates heat by the current. The water reservoir 5 is heated by the heat. Due to the heating, the water temperature in the water reservoir 5 rises.

  Then, it progresses to step S3 and the control apparatus 14 judges whether the water temperature of the water storage part 5 is higher than 80 degreeC based on the detected temperature of the thermistor 8. FIG.

  When the water temperature of the water storage part 5 is 80 degrees C or less, it returns to step S2. When the water temperature of the water storage unit 5 is higher than 80 degrees Celsius for 1 minute, the sterilization of water is completed. In this case, the process proceeds to step S4, and the control device 14 turns off the heater 7.

  Then, it progresses to step S5 and the control apparatus 14 sets the ultrasonic element 9 and the vibrator 12 to ON state. By the intermittent operation of the ultrasonic element 9, the water in the water reservoir 5 is refined at the interface. That is, the water in the water storage unit 5 is atomized. By the atomization, the substantially central portions of the atomizing chamber 10 and the pressurizing chamber 11 are filled with the high-humidity air 15. At this time, the high-humidity air 15 is not diffused but is held in the substantially central portion of the atomizing chamber 10 and the pressurizing chamber 11.

  At this time, water droplets jump from the water storage unit 5 as a water column. The water drops are collected in the water storage section 5 through the wall surface of the atomization chamber 10. On the other hand, condensed moisture adheres in the atomization chamber 10. The moisture is collected in the water storage section 5 through the inclined surface 10a.

  In the vibrator 12 that is in the ON state, a drive signal is input to the voice coil 12a. By this input, the voice coil 12a is electromagnetically driven with the magnet 12c. Due to the electromagnetic drive, the diaphragm 12b intermittently vibrates in the vertical direction with the inside of the pressurizing chamber 11 as a drive region 11b without contacting the wall surface of the pressurizing chamber 11.

  Due to the vibration, the volume in the pressurizing chamber 11 varies. Due to the fluctuation, the high-humidity air 15 in the pressurizing chamber 11 is pressurized. At this time, the excitation force is strongest in the vicinity of the center portion of the diaphragm 12b. Due to the pressurization, the high-humidity air 15 in the pressurizing chamber 11 passes through the opening 11 a and moves to the atomizing chamber 10. By the movement, the high-humidity air 15 in the atomization chamber 10 is also pressurized. At this time, amplification due to resonance of abnormal noise generated in the pressurizing chamber 11 is prevented by rubber or the like.

  The high-humidity air 15 moves in the vortex ring production tube 13 outward in the horizontal direction. At this time, the high-humidity air 15 is decelerated by friction with the inner peripheral surface of the vortex ring generating tube 13. For this reason, a wind speed distribution of the high-humidity air 15 is formed between the vicinity of the inner peripheral surface of the vortex ring generating tube 13 and the center of the vortex ring generating tube 13. Due to the wind speed distribution, a vortex is generated in the vicinity of the inner peripheral surface of the vortex ring generating tube 13. As a whole, the swirl-like high-humidity air 15 is discharged from the outlet opening 13a by the swirl.

  The high-humidity air 15 translates in a direction away from the main body case 1. Thereafter, the outer peripheral part of the vortex ring of the high-humidity air 15 gradually diffuses. As a result, thereafter, the high-humidity air 15 cannot maintain the shape of the vortex ring. As a result, the high-humidity air 15 is mixed with other air.

  Then, it progresses to step S6 and the control apparatus 14 judges whether the water temperature of the water storage part 5 is higher than 80 degreeC based on the detected temperature of the thermistor 8. FIG. When the water temperature of the water storage part 5 is 80 degrees C or less, it returns to step S2. When the water temperature of the water storage unit 5 is higher than 80 degrees Celsius, the process proceeds to step S7.

  In step S <b> 7, the control device 14 determines that the amount of water in the water supply tank 2 is 0 based on whether the power supply SW is in the OFF state, whether the set time of the timer has elapsed, and the detection result of the water level detection means 6. It is determined whether or not. If neither condition is satisfied, the process returns to step S3. If any condition is satisfied, the process proceeds to step S8. In step S8, the operation of the fluid conveyance device is finished.

  Next, a maintenance method after the operation of the fluid conveyance device is completed will be described with reference to FIG.

  First, the user removes the lid 1a at the dividing point A. Thereafter, the user discharges the water remaining in the water supply tank 2, the water supply unit 3, the water supply channel 4, and the water storage unit 5 out of the main body case 1. By the discharge, the propagation of bacteria and the generation of malodor in the water supply tank 2 and the like are suppressed when the fluid conveyance device is not used. At this time, the user can surely wipe the water remaining on the pressure surface (lower surface) of the diaphragm 12b. For this reason, the propagation of bacteria and the generation of malodor on the diaphragm 12b are suppressed.

  According to the first embodiment described above, the high-humidity air 15 is in a confidential state with high density in a minimum space. The high-humidity air 15 is efficiently pressurized by the vibrator 12. For this reason, even if the product size of the fluid conveyance device is small, it is possible to generate a vortex ring having high density and stable propulsive force.

  Further, it is not necessary to use a pipe or a blower fan for conveying the high-humidity air 15. For this reason, the number of parts is also reduced. As a result, the fluid conveyance device can be made inexpensive.

  In addition, by reducing the space in contact with the high-humidity air 15, the inflow of the high-humidity air 15 to a place where pressurization is difficult is suppressed. For this reason, a fluid conveyance apparatus can be kept hygienic.

  The diaphragm 12b has a larger area than the opening 11a on the horizontal projection plane. For this reason, the high-humidity air 15 in the atomization chamber 10 can be pressurized reliably.

  Moreover, the opening part 11a is formed just under the substantial center of the diaphragm 12b. For this reason, the high-humidity air 15 in the atomization chamber 10 can be pressurized more reliably and without loss.

  Further, the vortex ring generating tube 13 is set to have a horizontal length so as to become a vortex ring when the high-humidity air 15 is released. For this reason, it is possible to suppress the high-humidity air 15 from naturally flowing out without becoming a vortex ring. Therefore, the fluid conveyance device does not wet the surrounding floor. Moreover, the aesthetics of the fluid conveyance device are not impaired.

  A space is formed below the outlet opening 13 a of the vortex ring generating tube 13. The ridges other than the lower part of the outlet opening 13 a of the vortex ring generating tube 13 coincide with the side surface of the main body case 1. For this reason, the vortex ring discharged from the outlet opening 13a does not come into contact with the components of the fluid conveyance device. Therefore, the vortex ring does not collapse.

  Further, moisture condensed on the wall surface of the atomizing chamber 10 and the wall surface of the pressurizing chamber 11 is collected in the water storage section 5 through the inclined surface 10a. Therefore, water can be reused efficiently and hygienically. Further, a water recovery path is not required. For this reason, a fluid conveyance apparatus can be made small and cheap.

  Further, the water reservoir 5 is provided adjacent to and directly below the opening 11 a of the pressurizing chamber 11. For this reason, scattering of water droplets by the water column can be prevented.

  Note that the humidified air 15 may be generated by evaporating the water in the water storage unit 5 by heating the heater 7. In this case, the ultrasonic element 9 becomes unnecessary. For this reason, a control circuit etc. can be simplified. As a result, the fluid conveyance device can be made small and inexpensive. In this case, the visibility of the vortex ring is slightly deteriorated. However, the vortex ring can be experienced by touching.

  Moreover, you may convey the air containing fragrances, such as essential oil. In this case, there is no visibility of the vortex ring. However, the vortex ring can be experienced by sniffing.

  Further, the lid 1a may be removed at the dividing point A and the water storage unit 5 may be directly supplied with water. In this case, the operation continuation time of the fluid conveyance device is shortened. However, the water supply tank 2, the water supply path 4, etc. become unnecessary. For this reason, a fluid conveyance apparatus can be made small and cheap. The said structure is effective especially when conveying fragrance when humidification is unnecessary.

  Further, the ultrasonic element 9 may generate high-humidity air 15 for one vortex ring. In this case, the vortex ring can be reliably discharged by holding one vortex ring in the atomizing chamber 10 and vibrating the diaphragm 12b in the vertical direction. Moreover, the atomization chamber 10 can be reduced in size.

  Further, it is not necessary to limit the position of the control device 14.

FIG. 5 is a plan view of the fluid conveyance device according to the second embodiment of the present invention as viewed from below. In addition, the same code | symbol is attached | subjected to Embodiment 1 and an equivalent part, and description is abbreviate | omitted.

  The water storage section 5 of the first embodiment is provided immediately adjacent to the opening 11 a of the pressurizing chamber 11. On the other hand, the water reservoir 5 of the second embodiment is provided directly below the opening 11a of the diaphragm 12b. The vortex ring production tube 13 is set to an arbitrary length. For this reason, the highly humid air 15 and the water droplets of the water column do not flow out of the fluid conveyance device.

  According to the second embodiment described above, the fluid conveyance device can be made smaller than in the first embodiment.
