[0001] The present invention relates to a misting fan device, also known simply as a mist fan. [Background technology]

[0002] Various types of fans with spray nozzles that utilize the temperature drop caused by the heat of vaporization of sprayed water have been proposed. For example, Patent Document 1 discloses an agitating fan with a fine mist device for low-pressure water, which is intended to improve agitating fans used in agriculture, livestock farming, etc.

[0003] This mixing fan has an impeller fixed to the output shaft of a motor, a spiral-shaped stator vane provided in front of the impeller, nozzles provided at specified angular intervals around the outer circumference of the stator vane, a circular pipe that supplies water to the nozzle, a connecting pipe equipped with a pump that supplies water to the piping, a tank that communicates with the connecting pipe and stores water, and a bypass pipeline equipped with an electromagnetic valve and bypassing the pump.

[0004] It is also described that with this stirring fan configuration, by closing the solenoid valve when the pump is operating, the residual pressure in the pump can be returned to the tank, thereby preventing water droplets from falling from the nozzle.

[0005] Patent Document 2 proposes a fountain fan that lowers the air temperature. This fountain fan is a device that achieves water-cooling and humidifying effects by ejecting water from a water storage tank as a light mist or water from a fountain nozzle and dispersing the mist or water into a room or the air.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A spray fan device according to one embodiment of the present invention will now be described with reference to the drawings. [First embodiment] FIG. 1 is a perspective view of the spray fan device as seen from the right of the air outlet side, and FIG. 2 is a front view as seen from the air outlet side.

[0017] 1 to 5, the front-to-rear direction of spray fan device 1 is the direction showing the depth when the surface having air outlet 15 is viewed as the front, and is the direction shown as the front-to-rear direction in Fig. 1. The lateral direction or width direction of spray fan device 1 is the direction perpendicular to the front-to-rear direction in a plan view, and is the direction shown as the left-right direction in Fig. 1.

[0018] The right side is the right direction when viewed from the front, and the left side is the left direction. The height direction of the spray fan device 1 is the direction in which the spray fan device 1 is installed upright on the installation surface 46, and is the direction shown as the up-down direction in Fig. 1. Note that these orthogonal three-axis coordinate systems are used for the convenience of expressing the configuration of the spray fan device.

[0019] As shown in Figures 1 to 8, the spray fan device 1 has a fan 6 (see Figure 3) provided in a housing 38, air intakes (in this embodiment, right-side air intake 4A and left-side air intake 5A) provided in the housing 38, an air outlet 15 provided in the housing 38, an air guide passage 14 (see Figure 3) that guides the air from the fan 6 to the air outlet 15, at least one spray nozzle portion 20 provided in the outer area of ​​the air outlet 15, and a water pipe guide portion 28 having an insertion passage 26 (see Figure 8) for passing a water pipe 24 (see Figure 8) such as a hose 23 (including a tube) from a water supply means (not shown) such as a water faucet.

[0020] As shown in Figure 8, the water tube guide portion 28 is integrally provided along the lower outer wall of the spray fan device 1 (the lower peripheral surface 3K of the body 3 is shown as being the case), and the water tube 24 is passed through the insertion passage 26, and the water supply side connector 22 of the water tube 24 is connected to the nozzle side connector 21 of the spray nozzle portion 20.

[0021] (Overall appearance) The housing 38 of the spray fan device 1 according to this embodiment is shown to have a body 3 that houses a fan 6, a right side wall 4 and a left side wall 5 that are substantially trapezoidal and form the left and right side walls of the body 3 in a side view, and a main body head 2 connected to the upper part of the body 3. The fan 6 is attached inside the body 3 and rotates around a support shaft 13 (see FIG. 4) that is horizontally suspended parallel to the installation surface 46. The right side wall 4 and the left side wall 5 are provided with a front inclined column 7, a rear inclined column 8, a bottom column 9, and an upper column 17 that correspond to the front and rear sides of the trapezoid.

[0022] A right side air intake port 4A and a left side air intake port 5A, each of which is substantially rectangular, are provided on the right side wall portion 4 and the left side wall portion 5. The right side air intake port 4A and the left side air intake port 5A are provided with a right slit cover 4B and a left slit cover 5B, each of which has an intake opening.

[0023] The fan 6 may be configured as a double-suction fan with intakes on both the left and right sides. This configuration has the advantage that it can take in outside air from both sides, improving suction efficiency and allowing more air to be sent to the air outlet 15 even with the same size.

[0024] The rear sides of the pair of left and right upper pillars 17 extend rearward to form a U-shaped connecting part 43. This connecting part 43 can also be used as a handle 10. If necessary, the base end of the connecting part 43 can be made rotatable.

[0025] As shown in Figures 3 and 4, the spray fan device 1 is provided with a right air intake 4A and a left air intake 5A, and air sucked in from the left and right sides is guided from an opening (not shown) in the circumferential part of the fan 6 to an air guide duct 14 and released to the outside from an air outlet 15 connected to the air guide duct 14. A front base plate portion 18 is provided between the pair of left and right base pillars 9 at the front end position so as to span the left and right sides, and a rear base plate portion 19 is provided at the rear end position so as to span the left and right sides.

[0026] In addition, the "housing 38" in this invention refers to the outer component of the spray fan device 1, and it is not necessary for the entire device to be covered with the housing components. For example, even if the body 3 that houses the fan 6 and the components that make up the air outlet 15 are exposed to the outside, they are included in the "housing 38".

[0027] (Vent and louver configuration) As shown in Fig. 1, a substantially rectangular air outlet 15 is provided on the front surface of the forward protruding portion 2T of the main body head 2. A left-right louver 45 (a left-right movable blade) that can be manually or otherwise adjusted to change the left-right angle of the blown air is attached to the air outlet 15. If necessary, a plurality of up-down louvers 44 (up-down movable blades) that can be manually or otherwise adjusted to change the up-down direction of the blown air can also be attached.

[0028] Although the manufacturing cost will be higher, a louver angle adjustment unit (not shown) can be provided that automatically changes the inclination angle of the left-right louvers 45. In this case, the adjustment operation by the louver angle adjustment unit can be a mode in which the louver is maintained in a state tilted to the right or left, or a mode in which the louver is automatically swung (reciprocating left and right). The adjustment operation of the louver angle adjustment unit is set by the operation unit 12 (see FIG. 3). Similarly, the up-down louvers 44 can also be automated as necessary. By providing the left and right louvers 45 at an internal position of the air outlet 15, the direction of the blown air can be set to a state preferred by the user.

[0029] (Ingenious arrangement of air outlet and spray nozzle) As shown in Figs. 1 and 3, the forward protrusion 2T of the head portion 2 is provided to protrude forward from the front position of the cylindrical body portion 3 that is disposed horizontally.

[0030] A piping storage section 41 is provided below the forward protruding section 2T of the main body head 2, and stores nozzle piping (not shown) that supplies water to the three spray nozzle sections 20. The piping storage section 41 is provided with a nozzle attachment section 36 (see FIG. 1) having a surface that is inclined obliquely upward and rearward. A nozzle side connector 21 that communicates with the spray nozzle section 20 is fixed to the underside of the piping storage section 41.

[0031] In addition, while a conventional mist fan has the spray nozzle section 20 located inside the air outlet 15, the spray fan device 1 according to this embodiment is characterized in that the nozzle outlet 20F of the spray nozzle section 20 is located outside the air outlet 15. This configuration prevents water droplets from entering the inside of the air outlet 15 and adversely affecting the internal electrical components.

[0032] 1 and 4, the spray nozzle section 20 is provided in front of the air outlet 15, and the angle θ between the opening direction 40 of the air outlet 15 and the spray direction 39 of the spray nozzle section 20 is preferably set to 10° or more and 70° or less. Also, the distance d between the rearmost end position of the air outlet 15 and the nozzle outlet 20F is preferably set to 0 mm or more and 10 mm or less.

[0033] (Water pipe guide) 1, 2, 5, and 6 to 8 are diagrams for explaining the characteristic configuration of the water tube guide portion 28 according to this embodiment. FIG. 6 is a perspective view showing an example of the shape of the nozzle side divergent portion 32 in the water tube guide portion 28 as viewed from the front, and FIG. 7 is a perspective view showing an example of the shape of the water supply side divergent portion 33 in the water tube guide portion 28 as viewed from the rear. 8 is a schematic diagram showing a state in which a hose 23 provided with a water supply side connector 22 is passed through a water pipe guide portion 28. The water supply side connector 22 may be formed of only an opening for the hose 23, etc., which is connected by elastic deformation. As shown in FIG. 8, the water pipe guide portion 28 is provided with an insertion passage 26 for a water pipe 24 such as a hose 23 .

[0034] 1, 2 and 8, the lower peripheral surface 3K of the cylindrical body 3 is located above the position of the installation surface 46 of the bottom pillar 9, so there is a gap between the installation surface 46 and the lower peripheral surface 3K to which the water tube guide 28 can be attached. In this embodiment, the water tube guide 28 is provided along the lower peripheral surface 3K of the cylindrical body 3, so that the water tube guide 28 is configured in the shape of an arc-shaped guide 27 in side view, as shown in Fig. 8. By configuring it in the shape of an arc-shaped guide 27, the water tube 24 can be passed smoothly through the insertion passage 26 with less resistance.

[0035] As shown in Fig. 6, the water tube guide 28 is provided with a nozzle side opening 30 as the outlet of the water tube 24, and the nozzle side opening 30 is formed in a nozzle side divergent portion 32. An example of such a nozzle side divergent portion 32 is a shape that gradually widens, such as the shape of a trumpet tip. Similarly, as shown in Fig. 7, a water supply side divergent portion 33 is formed in the water supply side opening 31 as the inlet of the water tube 24, and has a substantially trumpet shape. This configuration makes it easier to insert and remove the water tube 24, such as the hose 23, into and from the water tube guide 28.

[0036] 8, the tip of the nozzle-side water pipe 24 is provided with a water supply-side connector 22 that can be connected to the nozzle-side connector 21. The water pipe 24, such as a hose 23 inserted into the water supply-side opening 31, is connected to a water supply means (not shown) such as a water faucet, and the supply pressure of the water from the faucet or the like causes the water to pass through the faucet, the water pipe 24, the insertion passage 26 of the water pipe guide 28, the water supply-side connector 22, the nozzle-side connector 21, the nozzle piping (not shown) in the piping storage section 41, and the spray nozzle section 20 to reach the nozzle outlet 20F, where it is released as a spray (mist).

[0037] In addition, as shown in Figure 2, the height H1 of the opening position of the nozzle side opening 30 from the installation surface 46 of the spray fan device 1 is set to 90 mm or less, and the distance between the water supply side connector 22 and the nozzle side connector 21 can be made long, making it easy to connect the water pipe 24 to the nozzle side connector 21.

[0038] (Operation unit) As shown in Fig. 3, in the spray fan device 1 of this embodiment, a trapezoidal plate-shaped operation unit mounting portion 11 is provided on the rear side of the left side wall portion 5, and an operation unit 12 is provided for adjusting the ON / OFF and rotation speed of the spray fan device 1. The operation unit 12 shown in Fig. 3 is of a dial type, but it may also be of a touch panel type.

[0039] In addition, when the device has a louver angle adjustment unit (not shown) for automatically moving one or both of the left-right louvers 45 and the up-down louvers 44 as described above, the operation unit 12 is provided with left-right angle adjustment switches such as rightward, forward, and leftward, up-down adjustment switches such as upward, forward, and downward, and various operation switches for swing operation, etc.

[0040] (Usage of this embodiment) A usage pattern of the spray fan device 1 according to this embodiment will be briefly described below. First, when the spray fan device 1 is used for blowing air only and the spray nozzle section 20 is not used, water from the water supply should not be supplied to the spray nozzle section 20. In this case, it can be used as a simple blower by removing the nozzle side connector 21 and the water supply side connector 22 and removing the water pipe 24 inserted into the water pipe guide section 28. The fact that the water pipe 24 can be removed easily in this way is also an advantage of this device.

[0041] In addition, when using the spray fan device 1 by supplying water from a tap and spraying it from the spray nozzle section 20, the nozzle side connector 21 and the water supply side connector 22 are connected and the left and right louvers 45, etc. are adjusted so that the air blown and spray (mist) are emitted in the desired direction.

[0042] In this case, as shown in Figure 4, by setting the angle θ between the opening direction 40 of the air outlet 15 and the spray direction 39 of the spray nozzle portion 20 to be greater than or equal to 10° and less than or equal to 70°, the air blown out from the air outlet 15 can be mixed well with the mist and the distance the mist can reach can be extended.

[0043] By setting the distance d between the rearmost end position of the air outlet 15 and the nozzle outlet 20F to be 0 mm or more and 10 mm or less, most of the mist discharged from the nozzle outlet 20F can be carried in a predetermined direction by the blown air. By providing at least the left and right louvers 45 inside the air outlet 15, it is possible to supply blown air or mist in the left and right directions in response to the user's needs.

[0044] In addition, since the water pipe 24 is held over a long distance on the lower peripheral surface 3K of the body 3 by the arc-shaped guide portion 27, even if the water pipe 24 of the hose 23, etc. moves significantly due to external factors, it is possible to prevent the water supply side connector 22 from coming off the nozzle side connector 21 or the hose 23, etc. from breaking, making it impossible to supply water.

[0045] As shown in Figure 3, if necessary, a downward piping section (not shown) may be provided so that the water in the piping of the piping storage section 41 flows downward at the nozzle side connector 21, and the water in the spray nozzle section 20 is discharged from the nozzle side connector 21 in the water falling direction 35 of Figure 3, thereby preventing the occurrence of problems such as the proliferation of bacteria due to residual water.

[0046] [Other variations] The present invention is not limited to the above-described embodiment, and modifications are possible within the scope of the present invention. For example, in the present invention, an electric booster pump can be inserted in the water pipe 24 connected to a water supply means such as a water faucet to increase the water pressure in the spray nozzle section 20 and reduce the size of the spray water droplets, thereby increasing the spray intensity and distance. This modified example also has the advantage that the booster pump can be provided in the water pipe 24 upstream of the water supply opening 31, without changing the basic structure of the spray fan device 1.

[0047] Although the present invention has been described above by way of examples, the technical scope of the present invention is not limited to the configurations described in the above embodiments. The technical scope of the present invention should be determined based on the description of the claims of the utility model registration, and it goes without saying that various modifications, additions to the configuration, or improvements can be made within that scope.
