The bottom plate 1D constitutes the bottom surface of the mist generator, and the mist generator is installed at a desired location via the bottom plate 1D.

As shown in FIG. 1, the housing member 1C is provided with a lid portion 11 that covers the opening 11a, and a tank 12 that stores a liquid such as water is fixed to the lid portion 11. The tank 12 is slidable in the vertical direction with respect to the mist generator together with the lid portion 11, and the tank 12 is housed in the mist generator by inserting the tank 12 into the opening 11a and pushing the lid portion 11 downward. To. Further, in a state where the tank 12 is housed in the mist generator, the lid portion 11 constitutes the outer surface (a part of the back surface) of the mist generator as a part of the housing member 1C.

An opening is formed on the lower end side of the tank 12, and a valve body 13 for opening and closing the opening and a pin 14 connected to the valve body 13 are slidably attached in the vertical direction. The valve body 13 and the pin 14 are detachable from the mist generator together with the tank 12. When introducing the liquid into the tank 12, the liquid can be poured through the above-mentioned opening in a state where the tank 12 is turned upside down.

As shown in FIG. 1, below the tank 12 housed in the mist generator, a pin 15 slidably attached in the vertical direction and a chamber 17 and a chamber 18 communicating with the inside of the tank 12 are provided. ing. A valve body 16 attached to the pin 15 and sliding up and down together with the pin 15 is arranged between the chamber 17 and the chamber 18.

A flexible pipeline 19 (FIG. 2) is attached to the chamber 18.

As shown in FIG. 1, when the mist generator is lifted, the lower end of the pin 15 projects below the bottom surface of the mist generator. At this time, the valve body 16 is in a closed position that shuts off between the chamber 17 and the chamber 18. Further, the pin 14 is in a position where the lower end of the pin 14 comes into contact with the upper end of the pin 15, and the valve body 13 closes the opening on the lower end side of the tank 12.

When the mist generator is placed on a table or the like, the pin 15 whose lower end is in contact with the table is pushed by the table and slides upward. In this state, the valve body 16 opens between the chambers 17 and 18. Further, the pin 14 is pushed upward by the pin 15, and the valve body 13 opens the opening on the lower end side of the tank 12.

A mist generator 20 is provided below the substantially central portion of the mist generator. The mist generating portion 20 is attached to the housing member 1A via the support columns 72a and 72b (FIG. 1) and the mounting holes 28a and 28b (FIGS. 3B and 3E).

The mist generating portion 20 includes a heater mounting portion 21 to which a substantially flat plate-shaped heater 3 (FIG. 2) is mounted, and a heating chamber 22 for receiving a liquid between the heater 3 mounted on the heater mounting portion 21. The mist generating portion 20 may be formed of, for example, a resin or the like. The heating chamber 22 has a concave shape that is formed in a rectangular shape when viewed from the left and opens toward the left. This recess functions as a portion for storing the liquid to be heated. An uneven shape is formed inside the heating chamber 22 in order to control liquid bubbles during heating and boiling. The heater mounting portion 21 includes six screw holes 21a (FIGS. 3A and 3G) arranged around the heating chamber 22. The heater 3 is attached to the heater mounting portion 21 by a screw (not shown) screwed into the screw hole 21 so as to close the recessed heating chamber 22 from the left. The heater 3 has a rectangular shape when viewed from the left, and is attached to the heating chamber 22 via a packing member 21c (FIGS. 3A and 3G). The heater 3 is in close contact with the packing member 21c from the left side, and the airtightness around the heating chamber 22 is maintained. The liquid flowing into the heating chamber 22 comes into contact with the surface (heating surface) of the heater 3 exposed facing the heating chamber 22, is heated by the heat of the heater 3, and boils.

A heat insulating member 31 (FIG. 2) that suppresses heat dissipation from the heater 3 is attached to the left side of the heater 3. The heat insulating member 31 is formed in a shape that covers the entire surface of the heater 3 when viewed from the left. As a result, the heat from the heater 3 is suppressed from being released to the outside through the housing member 1C.

Further, the mist generating portion 20 includes a cylindrical flow path 23 extending in the vertical direction and a cylindrical flow path 24 provided above the flow path 23 and connected to the flow path 23. The flow path 24 is formed to have a diameter larger than that of the flow path 23, and is connected to the flow path 23 via a tapered portion 24a whose diameter increases upward.

On the lower end side of the flow path 23, a conduit attachment portion 23A to which the conduit 19 (FIG. 2) formed of a flexible material is attached is provided. The pipeline mounting portion 23A is hollow, and a fluid can pass through the inside. The pipeline mounting portion 23A is provided so as to project linearly to the right, and one end of the pipeline 19 is inserted and attached to the pipeline mounting portion 23A from the right direction. The other end of the pipeline 19 is connected to the chamber 18 (FIG. 1). Similar to the pipeline mounting portion 23A, the chamber 18 is provided with a mounting portion (not shown) protruding to the right from the chamber 18, and the other end of the pipeline 19 is inserted into the mounting portion from the right direction. Can be installed.

In this way, since one end of the pipeline 19 is inserted and attached to the pipeline attachment portion 23A from the side surface direction (right direction), the mist generator can be easily assembled. For example, when the housing member 1C to which the pin 15, the valve body 16, the chamber 17 and the chamber 18 are attached is attached to the housing member 1B to which the mist generating portion 20 or the like is attached, the pipe line 19 is deformed to form a pipe. One end of the road 19 can be easily inserted into the pipeline mounting portion 23A.

Further, the mist generating unit 20 includes a flow path 25 connecting the heating chamber 22 and the flow path 23, and a flow path 26 connecting the heating chamber 22 and the flow path 24. As shown in FIGS. 3A and 3G, the flow path 25 has a circular cross-sectional shape and extends in the left-right direction, and communicates with the heating chamber 22 near the lower end of the heating chamber 22. Further, as shown in FIGS. 3A and 3G, the flow path 26 has a rectangular cross-sectional shape and extends in the left-right direction, and communicates with the heating chamber 22 near the upper end of the heating chamber 22.

A diaphragm portion 24b (FIGS. 1 and 2) shaped to bend the flow path 24 is formed in the flow path 24, and an ultraviolet irradiation unit 4 (FIG. 1) communicating with the flow path 24 is formed above the throttle portion 24b. 1, Fig. 2) is provided. The ultraviolet irradiation unit 4 has a function of making the particle size of the mist finer by irradiating the mist supplied with the flow path 24 with ultraviolet rays.

Above the ultraviolet irradiation unit 4, a bellows 51 communicating with the flow path 24, a mist supply path 52, a throttle portion 53, and a discharge port 55 are provided. An opening 71 is formed in the housing member 1B, and the discharge port 55 and the throttle portion 53 are housed in the opening 71 to communicate the flow path 24 to the outside of the mist generator. In order to make the direction of the discharge port 55 adjustable, the members forming the mist supply path 52, the throttle portion 53, and the discharge port 55 rotate with respect to the housing member 1B via the mounting portion 56 (FIG. 2). It is mounted so that it can be moved. By deforming the bellows 51 in response to the rotation of the member, the direction of the discharge port 55 can be adjusted in the vertical direction while ensuring the communication state from the flow path 24 to the discharge port 55.

On the other hand, a circuit board 6 (FIG. 2) is provided on the right side of the mist generating portion 20. A power supply circuit for supplying commercial power to the heater 3 and the ultraviolet irradiation unit 4 is mounted on the circuit board 6. A cable (not shown) for supplying electric power is connected between the circuit board 6 and the heater 3 and between the circuit board 6 and the ultraviolet irradiation unit 4, respectively.

A support member 7 is arranged between the mist generating portion 20 and the circuit board 6. The support member 7 integrally supports the mist generating unit 20, the circuit board 6, and the ultraviolet irradiation unit 4.

Next, the operation of the mist generator of this embodiment will be described.

First, the tank 12 is filled with a liquid, the tank 12 is inserted into the opening 11a, the lid 11 is pushed downward, and the tank 12 is housed in a mist generator placed on a table or the like. At this time, since the pin 15 is pushed upward, the valve body 13 and the valve body 16 are in the open position, so that the liquid in the tank 12 is the chamber 17, the chamber 18, the conduit 19, and the conduit attachment portion 23A. It flows into the inside of the mist generating portion 20 (flow path 23) via the above. The inflowing liquid is also supplied to the heating chamber 22 via the flow path 25 as the liquid level rises.

The liquid supplied to the heating chamber 22 is heated by the heater 3, and when it boils, the vapor or mist generated by the boiling is introduced into the ultraviolet irradiation unit 4 as mist through the flow path 26 and the throttle portion 24b of the flow path 24. Will be done. Further, the mist having a fine particle size in the ultraviolet irradiation unit 4 is discharged forward from the discharge port 55 via the bellows 51, the mist supply path 52, and the throttle unit 53.

The liquid that has been cooled into droplets without being discharged from the discharge port 55 flows downward due to gravity and is collected in the flow path 23. The recovered liquid is reused.

As described above, in the present embodiment, since one end of the pipeline 19 is inserted and attached to the pipeline attachment portion 23A from the side surface direction (right direction), the mist generator can be easily assembled. be able to.

Further, the pipeline 19 supplies the liquid supplied from the tank 12 to the mist generating unit 20 from the side surface side (in the above embodiment, the right side surface side). Therefore, the pipeline 19 can be connected to the mist generating section 20 at an arbitrary position in the front-rear direction of the mist generating section 20. For example, in the above embodiment, the pipeline 19 is connected to the mist generating section 20 in the vicinity of the center in the front-rear direction of the mist generating section 20.

In this embodiment, the pipeline 19 extends in the front-rear direction and is bent in the direction of the arrow L near the connection position with the pipeline attachment portion 23A. As a result, the pipeline 19 and the conduit attachment 23A can be connected while forming the conduit attachment portion 23A in a straight line perpendicular to the extending surface (vertical surface) of the heating chamber 22. As a result, the moldability of the mist generating portion 20 is improved as compared with the case where the pipeline mounting portion 23A has a bent portion. Since the pipeline 19 is bent as described above, it may be formed of a flexible member that can be easily bent. As a result, the line 19 can be easily arranged as compared with the case where the line 19 is made of resin or the like.

Further, in this embodiment, as shown in FIGS. 3B and 3C, the pipeline attachment portion 23A is formed so as to overlap the flow path 24 when viewed in the vertical direction. As a result, it is possible to reduce the physique of the mist generating portion 20 in the direction intersecting in the vertical direction, and it is possible to reduce the size of the mold for manufacturing the mist generating portion 20.

Further, in this embodiment, as shown in FIGS. 3B and 3D, the pipeline attachment portion 23A is connected slightly above the lower end portion of the flow path 23. As a result, it is possible to prevent the liquid that can collect in the lower part of the flow path 23 from entering (backflowing) into the pipeline attachment portion 23A.

Further, in this embodiment, the pipeline mounting portion 23A is arranged near the center of the mist generating portion 20 in the front-rear direction. As a result, along with the flow path 23 and the flow path 25, the opening on the flow path 23 side of the pipeline mounting portion 23A can be arranged near the center of the mist generating portion 20 in the front-rear direction. In this case, since the flow path 25 can be arranged near the center of the heating chamber 22 in the front-rear direction, the liquid can be uniformly supplied to the heating chamber 22 along the front-rear direction via the flow path 25.

Here, the line L in FIG. 1 indicates the center of the mist generating portion 20 in the front-rear direction. The center of the mist generating portion 20 in the front-rear direction may coincide with the center of the heating chamber 22 in the front-rear direction and the center of the flow path 23 in the front-rear direction.

The vicinity of the center of the mist generating portion 20 in the front-rear direction can be, for example, a position within 5 mm forward or backward from the center (position of the line L) in the front-rear direction of the mist generating portion 20. However, for example, the pipeline 19 can be connected to the mist generating section 20 at a position in front of the center in the front-rear direction of the mist generating section 20. For example, the pipeline 19 can be connected to the mist generating section 20 at a position about 5 mm or more in front of the center of the mist generating section 20 in the front-rear direction. Preferably, the pipeline 19 is connected to the mist generating portion 20 at a position within 5 mm forward from the center of the mist generating portion 20 in the front-rear direction. When the pipeline 19 is connected to the mist generating section 20 at a position in front of the center of the mist generating section 20, the flow path 23 is provided at a position in front of the center of the mist generating section 20 in the front-rear direction, and the pipe is provided at this position. The road 19 may be connected to the flow path 23.

By the way, as described above, the conduit 19 is made of a flexible material, but if the deformation (curvature) at the time of mounting is too large, the liquid supply state is hindered, or the conduit 19 is used for a long period of time. 19 may be damaged. Alternatively, if the conduit 19 is significantly deformed at the time of mounting, the restoring force of the conduit 19 becomes large, which may lead to deterioration of workability when assembling the conduit 19. In this respect, the connection portion of the pipeline 19 to the mist generating portion 20, for example, according to this embodiment, the position of the pipeline mounting portion 23A is in the rear portion of the mist generating portion 20, for example, in the front-rear direction of the mist generating portion 20. It is not desirable to set it behind the center (position of line L). If the connecting portion of the pipeline 19 (that is, the position of the pipeline mounting portion 23A) is the rear portion of the mist generating portion 20, the length of the pipeline 19 is shortened by that amount, so that the pipeline 19 is deformed when mounted (that is, the position of the pipeline 19) This is because the curvature) tends to be large. In addition, it tends to be difficult to handle the pipeline 19. On the other hand, when the pipeline mounting portion 23A is arranged in front of the center of the mist generating portion 20 in the front-rear direction, the deformation of the pipeline 19 can be suppressed and the handling becomes easy.

By the way, since the tank 12, the valve body 16, the chamber 17, the chamber 18, and the like are arranged on the rear side of the mist generating portion 20, the rearmost position of the mist generating portion 20 is restricted by the layout of such components. receive. On the other hand, it is advantageous that the flow path 24 is arranged at a position overlapping the mist supply path 52 when viewed in the vertical direction, in that efficient ascent (guidance) of mist to the mist supply path 52 is promoted. Is. On the other hand, considering that it is more convenient for the user to have the discharge port 55 located above, it is advantageous that the mist supply path 52 is located rearward.

In this respect, in this embodiment, although the mist supply path 52, the flow path 23, and the pipeline attachment portion 23A are offset in the front-rear direction, the flow path 24 is partially viewed in the vertical direction with respect to the mist supply path 52. It is placed at a position that overlaps with. That is, the mist supply path 52 is arranged relatively rearward, and the pipeline attachment portion 23A is arranged near the center of the mist generating portion 20 in the front-rear direction, while the flow path 24 is viewed in the vertical direction to supply mist. It can be arranged at a position that partially overlaps the road 52.

Further, as described above, in this embodiment, a heat insulating member 31 (FIG. 2) that suppresses heat dissipation from the heater 3 is attached to the left side of the heater 3. By interposing the heat insulating member 31 between the housing 1 and the heater 3 in this way, the heat from the heater 3 is suppressed from being released to the outside through the housing 1, so that power saving is achieved. Can be done. Further, it is possible to suppress deformation of the housing 1 and damage to each part of the device due to heat release.

Further, in this embodiment, the mist generated in the mist generating unit 20 is provided with an ultraviolet irradiation unit 4 that irradiates the mist generated with ultraviolet rays, and the mist having a fine particle size is discharged from the discharge port 55 in the ultraviolet irradiation unit 4. Therefore, a mist having a finer particle size can be obtained as compared with the conventional apparatus.

Although the examples have been described in detail above, the present invention is not limited to the specific examples, and various modifications and changes can be made within the scope of the claims. It is also possible to combine all or a plurality of the components of the above-described embodiment.
