Japanese Patent Application Publication No. 2-282638

In the humidifier of Patent Document 1, when replenishing water to the water tank, it is first necessary to separate the top lid from the main body, but at this time, consideration must be given to where to place the separated top lid, and some users may This can sometimes be a nuisance. Since the top lid has a mist outlet, water droplets tend to adhere to the area around it, so if the top lid is placed on a desk or the like, there is a risk that the desk or the like will get wet with the water droplets that adhere to the top lid.

SUMMARY OF THE INVENTION An object of the present invention is to provide a humidifier equipped with a removable lid so that the user can place the lid in an appropriate position without having to worry about where to place the lid.

The humidifier according to the present invention has a humidifying unit 11 that vaporizes water to generate mist, a water tank 2 that supplies water to the humidifying unit 11, a mist discharge port 9, and an opening of the water tank 2 that can be attached or detached. It is characterized by comprising a tank lid 8 that can be freely opened and closed, and a lid support 132 on which the tank lid 8 separated from the water supply tank 2 is placed.

The lid support base 132 may be arranged inside the peripheral wall of the water tank 2 in plan view.

A configuration may be adopted in which the lid support stand 132 is disposed below the upper edge of the water tank 2.

In plan view, a configuration may be adopted in which a majority of the tank lid 8 placed on the lid support 132 is disposed inside the peripheral wall of the water tank 2.

A configuration may be adopted in which the lid support stand 132 is arranged above the full water level of the water tank 2.

The tank lid 8 is formed into a disk shape, and the peripheral edge of the tank lid 8 can be inserted into and placed on the lid support 132.

The lid support base 132 includes a lid receiving surface 147 that supports the peripheral edge of the tank lid 8 from below, and the lid receiving surface 147 may be formed in a downward convex arc shape.

The water passage hole 150 penetrating the lid support base 132 may extend downward from the bottom of the lid receiving surface 147.

The inclination angle θ with respect to the vertical plane when the tank lid 8 is placed on the lid support base 132 can be set to 25° or less.

It is equipped with a mist cylinder 7 that guides the mist generated by the humidification unit 11 upward, and an attachment cylinder 130 that is inserted into the mist cylinder 7 from above and fixed to the outer circumferential surface of the mist cylinder 7, and a configuration can be adopted in which the lid support base 132 is provided integrally with the attachment cylinder 130.

If the humidifier according to the present invention is provided with a lid support base 132 on which the tank lid 8 separated from the water tank 2 is placed, the tank lid 8 can be moved between the tank lid 8 and the water tank 2 when replenishing water to the water absorption tank 2. When separated from the water supply tank 2, the tank lid 8 separated from the water supply tank 2 can be placed on the lid support stand 132. According to this, the user does not have to worry about where to place the tank lid 8 and can place the tank lid 8 in an appropriate position, thereby improving the convenience of the humidifier. Since there is no need to place the tank lid 8 on a desk or the like, problems such as the tank lid 8 with water droplets wetting the desk or the like can be solved.

When the lid support base 132 is arranged inside the peripheral wall of the water tank 2, water droplets that have flowed down to the lid support base 132 along the tank lid 8 can be dripped into the water supply tank 2, so that the water droplets can be used as a humidifier. Prevents the surrounding area from getting wet.

If the lid support base 132 is arranged below the upper edge of the water tank 2, even if water droplets attached to the tank lid 8 are scattered due to the impact when the tank lid 8 is placed on the lid support base 132, Since much of the water can fall into the water supply tank 2, it is possible to prevent the area around the humidifier from getting wet due to water droplets adhering to the tank lid 8.

If the majority of the tank lid 8 placed on the lid support stand 132 is placed inside the peripheral wall of the water tank 2, even if water droplets adhering to the tank lid 8 drip without being transmitted, Since much of the water can be dropped into the water supply tank 2, it is possible to prevent the area around the humidifier from getting wet due to water droplets adhering to the tank lid 8.

When the lid support base 132 is arranged above the full water level of the water supply tank 2, it is possible to prevent the lid support base 132 and, by extension, the tank lid 8, from getting wet due to accumulated water in the water supply tank 2.

If the tank lid 8 is formed into a disk shape and the peripheral edge of the tank lid 8 is inserted into the lid support base 132 and placed on it, the user is not aware of the circumferential direction of the tank lid 8. Any part of the periphery can be inserted into the lid support base 132 and placed thereon without having to do so. Therefore, the tank lid 8 can be reliably placed on the lid support base 132 with a simpler operation.

The lid support base 132 includes a lid receiving surface 147 that supports the peripheral edge of the tank lid 8 from below, and if the lid receiving surface 147 is formed in a downward convex arc shape, the lid receiving surface Water droplets flowing down to 147 can be collected in one place at the bottom thereof. According to this, it becomes easy to dispose of the collected water droplets later, for example, by letting the collected water droplets flow out from the lid support base 132.

When the water hole 150 penetrating the lid support base 132 extends downward from the bottom of the lid receiving surface 147, water droplets collected at the bottom along the slope of the lid receiving surface 147 are passed through the water hole 150 to the lid. It can be discharged outside the receiving surface 147. According to this, it is possible to prevent water from accumulating on the lid receiving surface 147, so that it is possible to prevent the proliferation of various bacteria.

If the inclination angle θ with respect to the vertical plane when the tank lid 8 is placed on the lid support 132 is set to 25° or less, water droplets attached to the tank lid 8 can be transferred to the lid support 132 more reliably and quickly. Since the water can be allowed to flow down, it is possible to prevent water droplets adhering to the tank lid 8 from scattering and wetting the area around the humidifier. Moreover, since most parts of the tank lid 8 can be arranged inside the peripheral wall of the water supply tank 2, this also prevents the area around the humidifier from getting wet with water droplets dripping from the tank lid 8.

It includes a mist tube 7 that guides the mist generated by the humidifying unit 11 upward, and a mounting tube 130 that is inserted into the mist tube 7 from above and fixed to the outer peripheral surface of the mist tube 7. is provided integrally with the mounting cylinder 130, the lid support stand 132 can be supported by the mist cylinder 7 via the mounting cylinder 130. According to this, the lid support stand 132 can be supported stably. Further, the tank lid 8 supported by the lid support base 132 can be stably supported.

The opening on the upper surface of the lower gas supply 54 communicates with the upper gas supply 53, and the opening on the right side communicates with a mist fan 56, which will be described next.

The mist fan 56 is a centrifugal blower fan (sirocco fan) whose intake direction and exhaust direction are perpendicular to each other, and is fixed to the right side of the lower gas 54 on the front outer surface of the water storage section 44 with screws 55. Specifically, the mist fan 56 includes a spiral fan casing 58 and a cylindrical impeller 59 that rotates around a horizontal axis (front-back direction) within the fan casing 58. An intake port 60 of the mist fan 56 is formed on the front surface of the fan casing 58 so as to be concentric with the impeller 59 . An exhaust port 61 of the mist fan 56 is provided on the left side of the fan casing 58 , and the edge of the opening is inserted into an opening on the right side of the lower gas 54 , that is, an inlet 62 . That is, when the impeller 59 in the fan casing 58 is driven, the airflow formed by the impeller 59 flows into the lower gas 54 and causes the lower gas 54 and the upper gas 53 to rise in sequence. Note that the exhaust port 61 of the mist fan 56 is sloped gently upward toward the lower gas supply 54, thereby reducing the loss of air volume when diverting the airflow upward within the lower gas supply 54. can do.

As shown in FIG. 4, a main body side stepped portion 66 is formed in a circumferential manner in the middle of the upper and lower sides of the side surface of the mounting recess 3. As shown in FIG. A downwardly recessed notch 67 is formed at the rear end of the main body side step portion 66 (12 o'clock position in FIG. 6), and a lock piece 68 constituting the locking mechanism 4 is installed inside this notch recess 67. The tip of the is located. The base end of the lock piece 68 is housed between the outer case 16 and the humidifying case 35, and only the tip of the lock piece 68 is exposed toward the notch recess 67 through the window opened in the humidifying case 35. (See Figure 5). In addition, downwardly recessed engagement grooves 69 are provided at three locations (2 o'clock, 6 o'clock, and 10 o'clock positions in FIG. 6) on the main body side step portion 66 at equal intervals in the circumferential direction. The lower surface of the cutout recess 67 is sloped downward toward the center of the mounting recess 3 , so that water droplets that have entered the cutout recess 67 are discharged along the slope, and the water droplets in the cutout recess 67 are removed. It is possible to prevent the accumulation of By preventing the water droplets from accumulating, water droplets can be prevented from entering the inside of the humidifying case 35 through the window for the lock piece 68, and corrosion (rust) of the springs and the like that constitute the lock mechanism 4 can be prevented. .

A circumferential tank side step portion 71 is also provided at the lower part of the outer peripheral surface of the water supply tank 2 . At the rear end of the tank side step 71 (12 o'clock position in FIG. 8), there is a U-shaped lock frame 72 that protrudes downward, corresponding to the notch recess 67 and lock piece 68 of the main body side step 66. are provided at three locations on the tank side step 71 (2 o'clock, 6 o'clock, and 10 o'clock positions in FIG. 8), and downwardly extending grooves 69 are provided in the tank side step 71 (at 2 o'clock, 6 o'clock, and 10 o'clock positions in FIG. 8). Projecting engagement protrusions 73 are provided at equal intervals in the circumferential direction.

When the water tank 2 is inserted into the mounting recess 3 from above, the tank side step 71 of the water tank 2 is received by the main body side step 66 of the mounting recess 3, and each engagement protrusion 73 enters each engagement groove 69. At the same time, the lock frame 72 enters the notch recess 67, and the lock piece 68 engages with the lock frame 72 (see FIG. 9). The engagement between each engagement protrusion 73 and each engagement groove 69 and the engagement between the lock frame 72 and the notch recess 67 restrict the rotation of the water tank 2 around the vertical axis with respect to the device main body 1. The engagement of the lock frame 72 prevents the water tank 2 from coming out of the mounting recess 3 unintentionally. These regulations allow the water tank 2 to be stably maintained in the attached state. The engagement protrusion 73 (engagement groove 69) and lock frame 72 (notch recess 67) also function as a guide (positioning) for the user to mount the water tank 2 at a proper position within the mounting recess 3.

The lock piece 68 is disposed inside the notch recess 67. In other words, the structure for restricting the water tank 2 from slipping out and the structure for restricting the rotation of the water tank 2 are located inside the mounting recess 3. It is consolidated in one place. Further, the lock frame 72 of the water tank 2 has a structure that engages with the lock piece 68 to restrict the water tank 2 from slipping out, and a structure that engages with the notch recess 67 to restrict the rotation of the water tank 2. Therefore, both structures are integrated in one place in the water supply tank 2 as well. According to such an integrated arrangement, the space of the mounting recess 3 and the water tank 2 that is not occupied by both of the above-mentioned structures can be widened, and other structures can be relatively freely arranged in the space.

A flat bottomed cylindrical tank base 75 is attached to the bottom of the tank body 6 of the water tank 2 from the outside. The tank base 75 is accommodated in the lower half of the mounting recess 3 (below the main body side step 66) when the water supply tank 2 is mounted, and is supported on the bottom surface of the mounting recess 3. As shown in FIG. 9, an engaging recess 76 recessed inwardly (upwards) is formed at the rear of the lower surface of the tank base 75, and a power receiving terminal 77 is fixed to the bottom of the engaging recess 76. When the water supply tank 2 is attached, the engagement recess 76 engages with the engagement protrusion 45 on the bottom of the attachment recess 3, and the power receiving terminal 77 contacts the power supply terminal 37 exposed from the slit 46. As a result, the power supply terminal 37 and the power reception terminal 77 become energized. According to the above embodiment, it is not necessary for the user to connect the terminals 37 and 77 separately from attaching the water tank 2, thereby improving the user's convenience. The power feeding terminal 37 and the power receiving terminal 77 are subjected to arbitrary waterproofing treatment. The power supply terminal 37 functions as a sensor that detects whether or not the water supply tank 2 is attached, and whether or not the water supply tank 2 is attached is determined based on whether or not electricity is supplied from the power supply terminal 37 to the power receiving terminal 77. . In a state where power is not supplied from the power supply terminal 37 to the power reception terminal 77, it is assumed that the water supply tank 2 is not attached, and an error is displayed on the operation board 39.

The water tank 2 includes a float-type water storage sensor 79 that detects the water level in the tank body 6, a lighting device 80 that illuminates the inside of the tank body 6, and ozonated water (sterilized water) that is generated by electrolyzing the water in the tank body 6. It is equipped with electrical equipment such as an electrolysis device 81 (see FIG. 10) that converts water into water. These electrical devices are electrically connected to the power receiving terminal 77, and can be driven by receiving power from the power receiving terminal 77 when the water tank 2 is attached. The water storage sensor 79 consists of a float that floats on water in the tank body 6, a magnet attached to the float, a guide body that supports the float in a vertically movable manner on the top side of the bottom wall of the tank body 6, and a guide body that supports the float in a vertically movable manner on the top side of the bottom wall of the tank body 6. and a Hall element attached to the lower surface side. When the amount of water stored in the tank body 6 is sufficient, the float floats up to its limit, and at this time the magnet is located outside the detection range by the Hall element. When the amount of water stored in the tank body 6 decreases and there is only a little left, the float descends and the magnet is detected by the Hall element, and in response to this, an error message is displayed on the operation board 39 indicating that there is no more water in the tank body 6. is displayed.

As shown in FIG. 11, a water supply channel 83 is formed inside the tank base 75 for supplying ozone water in the tank body 6 to the apparatus body 1. The water supply channel 83 connects a water supply port 84 provided at the bottom of the tank body 6 and a drip port 85 provided at the bottom of the tank base 75, and is formed in a crank shape as a whole. The dripping port 85 is located directly above the dripping position P of the water receiving wall 48 when the water supply tank 2 is attached. A filter member 86 for filtration is detachably attached to the water supply port 84 from the inner surface of the tank body 6, thereby preventing foreign matter from entering the water supply channel 83.

Specifically, the water supply channel 83 includes a first water supply body 88 on the upstream side extending downward from the water supply port 84 and a second water supply body 89 on the downstream side extending from the lower end of the first water supply body 88 to the drip port 85. Of these, the second water supply body 89 is provided with a water passage hole 91 that is opened and closed by an on-off valve 90. The on-off valve 90 is composed of a solenoid that includes a frame 92 fixed to the lower surface of the tank body 6 and a plunger 93 that is operated to move in and out from the lower surface of the frame 92, and is electrically connected to the power receiving terminal 77 to receive power. is supplied. The tip (lower end) of the plunger 93 faces the water passage hole 91 from above and can move toward and away from the water passage hole 91. The on-off valve 90 also includes a spring that biases the plunger 93 in a direction to protrude from the frame 92, that is, downward, and a coil that surrounds the base of the plunger 93.

In a normal state in which the on-off valve 90 is not energized, such as when the water storage section 44 is full of water or when the water supply tank 2 is separated, the tip of the plunger 93 biased by a spring comes into contact with the water passage hole 91 to close it. That is, the water supply channel 83 is closed and the water supply from the water tank 2 to the main body 1 of the apparatus is cut off. On the other hand, when the coil of the on-off valve 90 is energized, an upward electromagnetic force is generated that acts on the plunger 93, and the plunger 93 rises against the biasing force of the spring (retreats into the frame 92), causing the water passage hole to rise. Move away from 91 and open this. That is, the water supply channel 83 is opened and water is supplied from the water supply tank 2 to the main body 1 of the apparatus.

As shown in FIG. 10, the water supply tank 2 is attached to the mounting recess 3 on the top of the device main body 1 and is positioned above the water storage section 44. The water in the water supply tank 2 flows down the crank-shaped water supply path 83 from the water supply port 84 at the bottom of the tank main body 6, drips from the drip port 85 at the bottom of the tank base 75 onto the water receiving wall 48, and flows down the water receiving wall 48 into the water storage section 44. Thus, in this embodiment, water can be sent to the water storage section 44 simply by allowing it to freely fall from the tank main body 6 of the water supply tank 2. In other words, a drive system such as a pump is not required to send water to the water storage section 44, and the water supply structure can be simplified.

The full water level of the water storage section 44 is set at the lower end (left end) of the water receiving wall 48, and the water supply tank 2 (tank base 75) and its dripping port 85 face this water receiving wall 48 from above. In other words, the water supply tank 2 and its dripping port 85 are located above the full water level of the water storage section 44, which prevents the water supply tank 2 from being immersed in water stored in the water storage section 44. The surface of the water tank 2 is not wetted with water. Further, as described above, when the water supply tank 2 is separated from the apparatus main body 1, the water supply channel 83 (dropping port 85) is closed by the on-off valve 90. Therefore, when the water supply tank 2 is separated from the apparatus main body 1 and carried, it is possible to prevent the surroundings of the apparatus main body 1 from getting wet with drops dripping from the surface of the water supply tank 2 or the drip opening 85.

The mist cylinder 7 is formed into a cylindrical shape that extends vertically by vertically connecting an upper cylinder body 96 provided integrally with the tank body 6 and a lower cylinder body 97 provided integrally with the tank base 75. Strictly speaking, it is formed in an upwardly tapered shape whose diameter gradually decreases from the lower end to the upper end. The upper cylindrical body 96 is formed inside the tank body 6 so as to be concentric with the circumferential surface thereof, and the lower cylindrical body 97 is similarly formed inside the tank base 75 so as to be concentric with the circumferential surface thereof. The opening on the lower side of the mist cylinder 7 directly faces the water storage section 44 from above when the water supply tank 2 is attached. That is, the mist generated by the humidifying module 36 ascends from the water storage section 44 up the mist cylinder 7 and is released from the discharge port 9. By gradually reducing the diameter of the mist cylinder 7, the wind speed of the mist can be increased and the mist can be sent further.

As shown in FIG. 9, the engaging recess 76 of the water tank 2 and the power receiving terminal 77 are arranged on the outside of the cylinder wall of the mist cylinder 7 (lower cylinder body 97). That is, when the water supply tank 2 is attached, the engagement recess 76 engages the engagement protrusion 45 of the device main body 1 on the outside of the mist cylinder 7, and the power reception terminal 77 and the power supply terminal 37 come into contact. According to the above configuration, the mist rising up the mist tube 7 can be prevented from touching the power feeding terminal 37 and the power receiving terminal 77, and poor contact between the terminals 37 and 77 due to moisture can be prevented.

An air supply groove 98 is provided on the front side of the lower cylindrical body 97 in the tank base 75 to receive the upper part of the supply cylinder 52 when the water supply tank 2 is attached. The air supply groove 98 is a longitudinally long groove that is recessed inwardly (upwardly) from the lower surface of the tank base 75, and its rear end communicates with the inside of the lower cylinder body 97 without separating the wall. The air inlet 99 at the upper end of the air cylinder 52 opens forward and faces the front wall of the air groove 98 with a sufficient gap therebetween. Further, the left and right width dimensions of the air supply groove 98 are formed to be sufficiently larger than the same dimensions of the upper part of the supply cylinder 52, and there is a space between the air supply groove 98 and the left and right walls of the supply cylinder 52 to prevent the passage of airflow. There is a gap that allows for this.

In other words, the airflow formed by the mist fan 56 and rising through the blowing cylinder 52 is blown out forward from the air blowing port 99 at its upper end, then collides with the front wall of the air blowing groove 98 and splits into left and right sides. The air flows backward along the left and right walls of the air supply groove 98. Thereafter, the mist reaches the lower cylinder body 97 of the mist cylinder 7, takes in the mist rising from the water storage part 44, moves up the mist cylinder 7, and is discharged from the discharge port 9. Note that the front wall of the air supply groove 98 is formed into an outward convex arc shape in plan view using the peripheral wall of the tank base 75 (see Fig. 8), so that the airflow from the air supply port 99 can be smoothly directed from side to side. You can change direction. In this way, when the mist fan 56 forms an airflow in the mist cylinder 7, the mist generated by the humidification module 36 can be carried on the airflow and efficiently emitted from the outlet 9 to the outside of the humidifier. Note that the operating current value of the mist fan 56 is constantly monitored, and if this current value is out of the normal range, an error is displayed on the operation board 39 to prompt inspection of the mist fan 56.

The upper end portion of the feed cylinder 52 is adjacent to the water storage portion 44, so that the path from the air feed port 99 of the feed cylinder 52 to above the water storage portion 44 can be shortened or simplified. When the air supply port 99 is opened only in the forward direction (horizontal direction), the upper surface of the supply cylinder 52 is closed, and water droplets and mist can be prevented from entering the supply cylinder 52 from the upper surface. Furthermore, when the air supply port 99 is opened in a direction away from the water storage section 44 , when the mist rising from the water storage section 44 flows backward toward the supply cylinder 52 , the mist enters the supply cylinder 52 from the air supply port 99 . can be restrained from doing so. Furthermore, when the air supply port 99 is opened in a direction away from the water receiving wall 48 , when the water dripping from the dripping port 85 of the water supply tank 2 splashes significantly on the water receiving wall 48 , the water droplets are removed from the air supply port 99 . Intrusion into the sending cylinder 52 can be prevented.

As shown in FIG. 12, the upper end of the mist cylinder 7 communicates with a mixing chamber 125 surrounded by a mist cover 123 and a holder unit 124. In this mixing chamber 125, the ozone gas floating in the tank body 6 is mixed with the mist rising from the mist cylinder 7. Further, the mixing chamber 125 communicates with a discharge chamber 127 surrounded by the tank lid 8 and the mist guide 126, and the discharge port 9 faces the front end of the discharge chamber 127. That is, the mist rising from the mist tube 7 turns into an ozone-containing mist in the mixing chamber 125, flows into the discharge chamber 127, and is discharged from the discharge chamber 127 to the outside of the humidifier via the discharge port 9.

Both the mist cover 123 and the holder unit 124 are made of resin molded products. The holder unit 124 supports the mist cover 123 from below, and is inserted into the mist cylinder 7 from above and fixed to its outer circumferential surface. It integrally includes a substantially cylindrical mounting cylinder 130 to be fitted, a saucer part 131 projecting in the radial direction from the outer peripheral surface of the mounting cylinder 130, and a lid support base 132 extending rearward from the rear surface of the saucer part 131. The saucer portion 131 is formed into a mortar shape as a whole, and its wall surface slopes upward toward the outside. The outer peripheral edge (upper edge) of the saucer portion 131 engages with the mist cover 123 and supports it from below. Details of the lid support stand 132 will be described later.

The mist cover 123 includes a mist wall 134 having an upwardly convex spherical shape that faces directly toward the upper opening of the mist tube 7 from above, a substantially cylindrical engagement tube 135 extending downward from the periphery of the mist wall 134, and an engagement tube 135 extending downward from the periphery of the mist wall 134. The indicator body 136 is integrally provided with an indicator body 136 that slopes downward from the front surface of the indicator body to the front side. The engagement tube 135 elastically engages with the outer peripheral edge of the saucer portion 131 of the holder unit 124. The indicator body 136 indicates the full water level in the tank body 6, and a position slightly below the lower end of the indicator body 136 corresponds to the full water level. On the upper surface of the indicator body 136, characters or the like can be displayed to inform the user that the lower end thereof is an indicator of the full water level. The mist wall 134 has a larger diameter than the upper opening of the mist tube 7 and is formed concentrically, and a plurality of mist holes 137 are provided at equal intervals in the circumferential direction on the periphery thereof to allow the passage of mist. In plan view, the group of mist holes 137 is arranged so as to surround the upper opening of the mist tube 7 from the outside (see FIG. 13).

A space surrounded by the mist wall 134 of the mist cover 123, the mounting tube 130 of the holder unit 124, and the saucer portion 131 constitutes a mixing chamber 125 in which ozone gas is mixed with the mist. Ozone gas generated by electrolysis of water by the electrolyzer 81 is floating inside the tank body 6, and a plurality of suction passages 140 for sucking the ozone gas into the mixing chamber 125 are provided in the holder unit 124. ing. Each suction path 140 consists of a groove that vertically passes through the holder unit 124, and is formed in an arc shape in plan view (see FIG. 13). The group of suction passages 140 is arranged so as to surround the upper opening of the mist cylinder 7 from the outside.

The mist rising from the mist tube 7 is received by the inner surface (lower surface) of the mist wall 134 and deflected in the radial direction of the mist wall 134. That is, a flow of mist flows from the mixing chamber 125 to the discharge chamber 127 via the mist hole 137. The outflow of this mist creates a negative pressure in the mixing chamber 125, and this negative pressure causes the ozone gas in the tank body 6 to be sucked into the mixing chamber 125 via the suction path 140 (Venturi effect). The ozone gas sucked in this way mixes with the mist in the mixing chamber 125, thereby generating ozone-containing mist.

When the ozone gas in the tank body 6 is sucked into the mixing chamber 125, mixed with mist, and released from the discharge port 9, the concentration of ozone gas in the tank body 6 is lowered to prevent it from being filled with high concentration of ozone gas. be able to. Thereby, when the tank lid 8 is separated from the tank body 6 and its upper surface is opened, the irritating odor of ozone gas felt by the user can be significantly reduced. In addition, the sterilizing effect of ozone gas can be added to the mist discharged from the discharge port 9. Further, by providing the mixing chamber 125 for mixing ozone gas into the mist, the ozone gas can be evenly distributed in the mist emitted from the outlet 9. If the distribution of ozone gas is uneven, there is a risk that the user receiving the mist may temporarily feel a strong odor of ozone gas, but according to the present embodiment, this risk can be significantly reduced.

Note that the mist rising from the mist tube 7 may contain relatively large water droplets. Most of these water droplets are caught and attached to the inner surface of the mist wall 134, and drip from the periphery of the mist wall 134 toward the bottom of the mixing chamber 125. The water then flows down one of the suction paths 140 extending downward from the bottom of the mixing chamber 125 (lower edge of the saucer part 131), travels along the outer surface of the mist cylinder 7, and joins the accumulated water in the tank body 6. In other words, the suction path 140 also serves as a recovery path 141 for returning water droplets contained in the mist into the tank body 6.

When the mist rising from the mist tube 7 is received by the upper wall of the mixing chamber 125, that is, the mist wall 134, relatively large water droplets contained in the mist are attached to the mist wall 134, and can be removed from the mist. In other words, a high-quality mist containing only minute water droplets and less likely to wet the user's skin can be emitted from the outlet 9. Furthermore, if the water droplets dripping from the mist wall 134 to the bottom of the mixing chamber 125 are made to join the accumulated water in the tank body 6 through the recovery path 141, it is possible to prevent the water droplets from accumulating in the mixing chamber 125, and to remove the water droplets from the mist. It can be reused as a raw material.

The mist guide 126 is made of a resin molded product formed into a shallow dish shape, and is fixed to the inner surface (lower surface) of the tank lid 8. A circular insertion hole 143 through which the mist wall 134 of the mist cover 123 is inserted is provided at the center of the bottom wall of the mist guide 126. Each mist hole 137 provided in the mist wall 134 opens obliquely upward toward the discharge chamber 127 surrounded by the tank lid 8 and the mist guide 126, so that the ozone-containing mist in the mixing chamber 125 is It can smoothly flow into the discharge chamber 127 through 137.

By separating the tank lid 8 from the tank body 6 and opening its top surface, the user can supply water into the tank body 6, more precisely between the inner peripheral surface of the tank body 6 and the outer peripheral surface of the mist tube 7. . The mist lid 134 that covers the upper opening of the mist tube 7 from above also serves as a protective cover to prevent the user from accidentally supplying water to the inside of the mist tube 7. On the outer surface (upper surface) of the mist lid 134, characters or the like can be displayed to inform the user that water should not be supplied to the inside of the mist cylinder 7.

As shown in FIG. 10, the peripheral wall of the tank body 6 is formed into a substantially truncated conical shape whose diameter decreases downward, and the upper part thereof is covered from the outside with a substantially cylindrical decorative cover 144. The upper end of the decorative cover 144 protrudes above the tank body 6, and the tank lid 8 is removably fitted inside the upper end. The tank lid 8 is made of a disc-shaped resin molded product, and a bayonet structure consisting of a protrusion and a groove extending in the circumferential direction is provided between the outer peripheral surface of the tank lid 8 and the inner peripheral surface of the decorative cover 144. There is. In other words, when the tank lid 8 is rotated inside the decorative cover 144, there are two states: a locked state (tank lid 8 cannot be lifted) in which the bayonet-structure protrusion engages with the groove, and an unlocked state (in which the protrusion leaves the groove). tank lid 8 can be lifted). Note that it is also possible to omit the decorative cover 144 and provide an engagement structure between the tank body 6 and the tank lid 8, so that the tank lid 8 can be directly attached to the tank body 6.

As shown in FIGS. 1 and 14, the tank lid 8 separated from the tank body 6 during water supply etc. can be placed on a lid support 132 behind the mist cylinder 7. Specifically, the lid support base 132 is formed in the shape of a gutter extending left and right, and the peripheral edge of the disk-shaped tank lid 8 is inserted into the lid support base 132 from above and placed thereon. According to the humidifier of this embodiment that includes the lid support base 132 as described above, the user does not have to worry about where to place the tank lid 8 and can place the tank lid 8 in an appropriate position, which is convenient. A humidifier with excellent performance can be obtained. Since there is no need to place the tank lid 8 on a desk or the like, problems such as the tank lid 8 with water droplets wetting the desk or the like can be solved. The tank lid 8 placed on the lid support stand 132 is a wall that catches some of the water splash from the water surface of the tank body 6 during water supply and prevents it from flying around the humidifier. functions as

The inner bottom surface of the lid support base 132 constitutes a lid receiving surface 147 that supports the peripheral edge of the tank lid 8 from below. In a rear view (front view), the lid receiving surface 147 is formed in a downward convex arc shape. Further, the lid receiving surface 147 slopes downwardly toward the rear, so that the tank lid 8 is also supported in an inclined posture that slopes backward. In this embodiment, the inclination angle θ of the tank lid 8 with respect to the vertical plane in the inclined position is set to 20°. It is preferable that the inclination angle θ is set within a range of 15° or more and 25° or less.

A regulating body 148 consisting of a protrusion extending rearward toward the lid receiving surface 147 is provided on the front wall of the lid support base 132. Correspondingly, the inner surface (lower surface) of the tank lid 8 has an annular shape. A regulated body 149 consisting of a protrusion is provided. The regulating body 148 engages with the lower end of the regulated body 149 of the tank lid 8 inserted into the lid support base 132, and tilts the tank lid 8 against the rotational moment in the direction in which it tends to fall. Hold the posture stably.

Although FIGS. 1 and 14 show the tank lid 8 in a horizontal position (position in which the opening of the tank body 6 is closed) with the front end inserted, the part of the tank lid 8 that can be inserted is limited to the front end. Instead, any part of the peripheral edge of the tank lid 8 can be inserted into the lid support 132. In other words, if the tank lid 8 is formed into a disk shape and the regulated body 149 is formed in an annular shape on its inner surface, the regulated body 148 will engage with the regulated body 149 regardless of the circumferential direction of the tank lid 8. Therefore, when the user inserts the tank lid 8 into the lid support base 132, there is no need to pay attention to the direction of the tank lid 8, thereby improving convenience. Further, the annular regulated body 149 functions as a dam that prevents water droplets adhering to the inner surface of the tank lid 8 from traveling to the peripheral edge and eventually to the outer surface.

When the tank lid 8 is placed on the lid support base 132, most of the water droplets attached to the tank lid 8 flow down the tank lid 8 to the lid receiving surface 147. A water passage hole 150 that penetrates the lid support base 132 extends downward from the rear end of the left and right center of the lid receiving surface 147, that is, from the bottom of the lid receiving surface 147 (see FIG. 15). According to this, water droplets flowing down from the tank lid 8 to the lid receiving surface 147 head toward the bottom along the slope of the lid receiving surface 147 and drip from the water passage hole 150 toward the bottom of the tank body 6. . As described above, since the lid receiving surface 147 of the lid supporting base 132 is formed into a downwardly convex arc shape and the water passage hole 150 extending downward from the bottom is provided, The collected water droplets can be discharged from the water passage hole 150 to the outside of the lid receiving surface 147. In other words, it is possible to prevent water from accumulating on the lid receiving surface 147. Therefore, it is possible to prevent bacteria from breeding in the water.

In plan view, the lid support base 132 is disposed inside the peripheral wall of the water supply tank 2. This allows water droplets that have flowed down the tank lid 8 to the lid support base 132 to drip into the water supply tank 2, preventing the area around the humidifier from getting wet. The lid support base 132 is also disposed below the upper edge of the water supply tank 2, which allows most of the water droplets to fall into the water supply tank 2 even if the water droplets on the tank lid 8 are scattered by the impact of placing the tank lid 8 on the lid support base 132, preventing the area around the humidifier from getting wet.

Since the lid support base 132 is arranged above the full water level (indicator 136) of the water supply tank 2, it is possible to prevent the lid support base 132 and, by extension, the tank lid 8, from getting wet due to accumulated water in the water supply tank 2. Note that the lid support base 132 and the index body 136 are arranged symmetrically in the front and rear with the mist cylinder 7 in between. According to this, when the tank lid 8 is inserted into the lid support base 132, the tank lid 8 does not cover the upper part of the index body 136, and the user can easily use the index when replenishing water to the water tank 2. The body 136 can be visually recognized. Therefore, the user can more reliably recognize the full water level of the water tank 2. Note that the positional relationship between the lid support 132 and the index body 136 is not limited to being symmetrical with the mist tube 7 in between; for example, either the lid support 132 or the index body 136 may be moved to the left or right side of the mist tube 7. Even if the phase around the mist tube 7 is different by 90 degrees, the same effect as described above can be obtained.

Since the majority of the tank lid 8, which is placed in an inclined position on the lid support base 132, is placed inside the peripheral wall of the water supply tank 2 in plan view, water droplets attached to the tank lid 8 drip without running down it. Even in this case, much of it can fall into the water tank 2. Therefore, it is possible to prevent the area around the humidifier from getting wet due to water droplets. At this time, the inclination angle θ of the tank lid 8 with respect to the vertical plane is set to 25 degrees or less (20 degrees in this embodiment), so that the water droplets attached to the tank lid 8 can more reliably and quickly flow down to the lid support 132. be able to. Therefore, this also prevents water droplets adhering to the tank lid 8 from scattering and wetting the area around the humidifier. Since most parts of the tank lid 8 can be arranged inside the peripheral wall of the water supply tank 2, this also prevents water droplets dripping from the tank lid 8 from getting wet around the humidifier.

The lid support base 132 of this embodiment is made of a resin molded product that is provided integrally with the saucer portion 131 and the mounting tube 130, and the mounting tube 130 is fixed to the outer peripheral surface of the mist tube 7. That is, the lid support stand 132 is supported by the mist cylinder 7 via the saucer part 131 and the mounting cylinder 130. According to this, the lid support base 132 and, by extension, the tank lid 8 can be stably supported without wobbling.

A user of a humidifier configured as described above can switch the humidifier between an operating state and a standby state by connecting the power cable 24 and operating the operation unit 41. When the humidifier is in an operating state, the various parts of the humidifying unit 11 and the purification unit 12 are driven to simultaneously generate mist and purified air. Of course, it is also possible to operate only one of the humidifying unit 11 and the purification unit 12 and generate only mist or purified air.

When the humidifying unit 11 is in operation, the humidifying module 36 and the mist fan 56 are mainly driven, and the generated mist is carried by the airflow and discharged from the discharge port 9 . Further, power is supplied from the power supply terminal 37 of the humidifying unit 11 to the on-off valve 90 of the water supply tank 2, and water is supplied from the tank body 6 to the water storage section 44 through the water supply channel 83. The opening and closing of the water supply channel 83 by the on-off valve 90 is controlled based on the output of the water level sensor 50 of the water storage section 44 . That is, during operation of the humidifying unit 11, when the water level sensor 50 detects that the water is full, the water supply channel 83 is closed, and when the water level sensor 50 detects a decrease in the water level, the water supply channel 83 is opened again.

The humidifier according to the present invention can contribute to goal 3 (health and welfare for all) of the Sustainable Development Goals (SDGs) advocated by the United Nations. The present invention can also be applied to a humidifier that does not have a purification unit 12 and does not generate purified air. In addition to the ultrasonic humidifier shown in the above embodiment, the present invention also includes a steam type (heating type) humidifier that heats and vaporizes water (the humidifying module 36 is a heater), and a water-containing filter that blows air. It can also be applied to a vaporization-type humidifier (the humidification module 36 is a fan) that vaporizes water by applying water.
