It is formed in a part].

In addition, as shown in FIG. 11, the tray 7 of the present embodiment is easily pulled out from the opening 1D of the lower part of the case main body 1A in the open state by pulling up the front panel 2. In order to enable this, the handle 7G is rotatably attached. Moreover, when the tray 7G is accommodated in the case body 1A lower part, this handle 7G is accommodated so that it may be enclosed under the bottom part of the tray 7, and it can avoid that it protrudes from the front side. have. In addition, when the tray 7 is pulled out of the case main body 1A, the handle 7G is rotated upward to a predetermined angle around the rotation support point 7D to maintain a temporary standing state to maintain the water supply tank ( In order not to disturb the take-out operation of 3), a pin-shaped stopper 7E is provided on the side surface of the tray 7.

Always submerged in

When the support dish 8 is provided in the lower part of humidification filter chamber S3, and the filter unit 4A is normally accommodated in humidification filter chamber S3, as shown in FIG. It is accommodated in the humidification filter chamber S3 in the state which stood in the longitudinal direction.

As shown in Figs. 6 and 12, the support plate 8 of the present embodiment has an arm having a substantially triangular plate shape in which the filter unit 4A is fitted from both sides on the outside of the filter unit 4A. It is integral with 8A, and is rotatably centered around the rotating shaft 8C provided in the lower part of 1 A of case main bodies.

Therefore, although it mentions later in detail, it is assumed that the interlock mechanism 20 operates in conjunction with the pulling operation of the front panel 2, and the filter unit 4A is pulled up to a predetermined height. Then, the support dish 8 installed in the lower part of the filter unit 4A also raises similarly, and the support dish 8 also rotates downward with this. After that, as shown in FIG. 12, when the rising position reaches to the part which climbed higher than the tray 7, it will release | release from the engagement operation | movement with the tray 7 which pushed the support plate 8 upward. For this reason, the support plate 8 advances directly under the filter unit 4A and stops in a horizontal state.

Thereby, since the water falling from the filter 4 accommodated in the filter unit 4A can be taken out by the support plate 8 directly under this, even if the tray 7 is not pulled out, it is upwards from the tray 7, for example. By spaced apart, the droplets falling from the filter 4 spaced from the liquid level can be avoided from scattering at the liquid level of the liquid dish 7B of the tray 7. As a result, it is possible to prevent the disinfecting liquid from scattering at a predetermined position inside the case main body 1A and causing various problems, for example, fouling in the apparatus, corrosion of the conductor, or short.

In addition, when the tray 7 is pulled out from the water supply tank chamber S1 of the case main body 1A to the water supply tank 3, the supporting plate 8 is moved upward as in the case where the filter unit 4A is raised. The support plate 8 is released from the coupling operation with the tray 7 which has been pushed up. As a result, in conjunction with the withdrawal operation of the water supply tank 3, the support dish 8 also advances immediately below the filter unit 4A and is stabilized in a horizontal state. Therefore, in this case as well, water falling from the filter 4 housed in the filter unit 4A can be picked up by the support plate 8, and the disinfectant liquid is scattered at a predetermined position inside the case main body 1A. Problems such as fouling in the equipment, corrosion of conductors or shorts can be prevented from occurring.

As shown in FIG. 6, the light source 9 of this embodiment is provided in the back side of the water supply tank 3, and is comprised from LED (Light Emitting Diode). The light source 9 of this embodiment is set to illuminate the water supply tank 3 for a predetermined time at least when the humidifier 1 is turned on and when the on timer is set. Thereby, attention can be called out to confirm the residual quantity of water in a tank from the exterior via the viewing window 2C provided in the front panel 2. As shown in FIG.

As shown in FIG. 1, the air filter 10 purifies the air before it is introduced from the outside and passes through the filter 4, and is inside the case body 1A facing the humidification filter chamber S3. In the back side, it is arrange | positioned facing the air inlet 1B.

As shown in FIG. 13, the control part 11 is a front part which the lower part of the case main body 1A is exposed with the pulling operation of the front panel 2. As shown in FIG. Parts and the like are housed in the control box 11A and unitized (or modularized).

In particular, in this control part 11, the signal line, the power line, etc. which plan the connection of the various sensors installed in the humidifier 1, CPU inside the control part 11, etc. are not exposed in the state exposed in the control room S5. The wires are all wired to the control box 11A from the rear surface of the partition plate. Therefore, when the front panel 2 is pulled up by hand or the like, a hand or the like can be caught on the signal line or the power line to prevent a dangerous accident such as disconnection or electric shock.

The ozone generator 12 removes unpleasant odors by sterilizing the air even if the filter 4 which is periodically immersed in the bactericidal solution releases air containing unpleasant odors due to fouling of bacteria or the like. In addition, the ozone generator 12 can also remove, for example, the smell of tobacco or animal smell floating in the room, and can also function as a deodorizer.

In addition, the ozone generator 12 of this embodiment passes through the filter 4 between humidification filter chamber S3 and blowing fan chamber S2 in case body 1A inside, as shown in FIG. It is provided on the flow path where the air | atmosphere which flows later.

The triangular plate 22 is provided with a rotating shaft 22A at an end (right end in FIG. 14) opposite to an end (left end in FIG. 14), which is a connecting portion with the connecting member 21, and through this rotating shaft 22A. The triangular plate 22 and the arm 23 are connected in a rotatable state.

In addition, between this triangular plate 22 and the case main body 1A, as shown in FIG. 16, when the front panel 2 lowers after the pulling operation of the front panel 2, the front panel 2 and the filter are performed. The damper mechanism 70 which prevents the rapid descending operation of the unit 4A is provided. In addition, the specific structure of the damper mechanism 70 of this embodiment is demonstrated in detail later.

Therefore, according to the linkage mechanism 20 of this embodiment, a finger etc. are inserted in opening BS1 of base body BS, and the lower part of front panel 2 is gripped and it raises upwards. Then, the rotating shaft 21A journaled to the rotating bearing 2A of the lower part of the front panel 2 raises with the raising operation of the front panel 2, and the raising operation at this time is made through the connecting member 21. As shown in FIG. By the left and right lifting force transmission means 20B constituted by the link mechanism, it is transmitted to the filter unit 4A as shown in FIG. 14, and a raising operation is performed. As a result, as shown in FIG. 5 from the state of FIG. 4, the front panel 2 and the filter unit 4A protrude from the upper surface of the case main body 1A.

Finally, when it rises to the uppermost position, the guide hook 24 (refer FIG. 4) of the case main body 1A is caught in the lowest part of the guide groove 2B of the front panel 2, and the case main body 1A is stuck. Leaf spring 13 (second lock mechanism 60B); 18] Since the lock state is temporarily held by being inserted into the spring plate member having elasticity, even if the front panel 2 is not held by hand, it is not lowered and the state is maintained as it is.

Thereby, since the tray 7 equipped with the water supply tank 3 can be taken out from the tank chamber S1 opened by the rise of the front panel 2, the water in the water supply tank 3 can be supplied. . At the same time, the filter unit 4A can be taken out to clean or replace the filter 4.

On the other hand, in order to lower the front panel 2, the locked state may be canceled. The lock releases the front panel 2 and the filter unit 4A by their own weight, but the sudden dropping operation is suppressed by the damper mechanism 70 and falls by a relaxed operation, so that an impact can be avoided. In addition, safety is secured.

In addition, as shown in FIG. 15 and FIG. 18, the first lock mechanism 60A and the second lock mechanism 60B are attached to the interlock mechanism 20.

Among these, although 60 A of 1st lock mechanisms are mentioned later in detail, the interlocking mechanism 20 operates, the filter unit 4A raises with the pulling operation of the front panel 2, and the case main body 1A After a part of the filter 4 protrudes from the open closing lid 1G, only the filter unit 4A lowers the single lowering operation.

On the other hand, the second lock means 60B will be described later in detail, but the front panel 2 is lowered at the time of supply of water to the water supply tank 3 (or cleaning of the liquid dish 7B or the filter 4). It is to prevent entry of the tray 7 so that the tray 7 can be safely moved in and out, and is operated when the front panel 2 is raised to a predetermined raised position to temporarily lock the front panel 2 at the raised position. It is.

(II) With respect to the electrode evacuation mechanism 30:

The electrode evacuation mechanism 30 raises the front panel 2 to supply the tray 7 to the tray 7 from the water supply tank chamber S1 at the lower front side of the case main body 1A (front side) opened from the shielded state. This is to prevent the draw-out operation of the water supply tank 3 when drawing out (3). In this invention, the electrode 6 (refer FIG. 9 and FIG. 10) drawn in the immersion state in the liquid pan 7B of the tray 7 by this electrode retracting mechanism 30 is retracted upwards.

As shown in FIGS. 9 and 10, the electrode evacuation mechanism 30 according to the present embodiment is provided in a suspended state from the lower end of the filter unit 4A on which the filter 4 extends. That is, the electrode retraction mechanism 30 of this embodiment is comprised by the simple thing which the electrode 6 hanged physically in the lower part of 4 A of filter units, and interlocks with the lifting operation of 4 A of filter units, and the electrode 6 ) Also rises and falls, so that when the filter unit 4A rises, the electrode 6 can also be evacuated from the immersion state in the liquid pan 7B.

Therefore, when the front panel 2 is pulled up from the case body 1A, the filter unit 4A is raised in conjunction with the operation of pulling up the front panel 2, and with this, the liquid dish of the tray 7 is raised. The antibacterial electrode 6 immersed in 7B also rises. Finally, when the filter unit 4A rises to a predetermined height, the disinfection electrode 6 also rises at least to a height that can exceed the wall 7C provided around the tray 7. Finally, the lowermost side of the disinfection electrode 6 reaches a position higher in height than the wall 7C of the tray 7. Therefore, with respect to the tray 7, for example, when taking out the feed water tank 3, the tray 7 can be pulled out in the horizontal direction without being caught by the disinfection electrode 6.

(III) For the valve opening and closing mechanism 40:

7, 8 and 11, the valve opening and closing mechanism 40 automatically closes the valve when the water supply tank 3 is lifted out of the tray 7 and the water supply tank 3 is closed. Returns to the predetermined position of the tray 7 to automatically start the water supply operation. In addition, the valve opening / closing mechanism 40 is provided with a water level detection float 43 constituting the water detection means and a magnet and a proximity sensor (not shown in detail) and a detection signal for the water level. 11), and in particular, in the control unit 11, when the water level is below a predetermined level, the water supply flashing lamp 1j of the operating unit 1E is operated so that the remaining water in the water supply tank is reduced so that it is urged to supply water ( To alert the user, illuminate the liquid level.

While the valve opening / closing mechanism 40 of the present embodiment includes a normally closed valve 41 at the lower portion of the water supply tank 3, the valve operation chamber 7F of the tray 7 shown in FIGS. 7 and 8 is provided. The valve opening / closing member 42 which opens the normally closed valve 41, and the water level detection float 43 which detects a water level and displays it externally are arrange | positioned at ().

As shown in FIG. 7, the normally closed valve 41 has a screw cover 41A screwed to a water supply port 3A provided at a lower portion of the water supply tank 3, and a central portion of the screw cover 41A. It is provided with the substantially plate-shaped stopper 41B provided in the inside, and the pin member 41C which was installed so that it could move up and down in the hole of the center part of the screw cover 41A, and fixedly installed the stopper 41B in the upper part. Doing. In addition, between the screw cover 41A and the stopper 41B, a tension spring (not shown) is interposed, and the valve is closed unless it is mounted on the tray 7 and opened by the valve opening / closing member 42. (Normally closed type)

On the other hand, the valve opening / closing member 42 has a substantially Loza (Japanese letter) frame accommodated in the valve operating chamber 7F, as shown in FIG. 11, and has a rotary shaft 42B provided in the middle portion. For the above-described water level detection, the end portions of which are loosely inserted in the state of being able to move up and down with respect to the lever main body 42A and the lever main body 42A in the vicinity of the rotating shaft 42B of the lever main body 42A and both end portions of the lever main body 42A as the rotational support points The water level detection float 43 is provided. In addition, in this embodiment, although the water level detection float 43 is loosely inserted in the center of 42 A of lever bodies, it is not limited to this structure in particular, Even if it is provided in the vicinity of 42 A of lever bodies, for example. do.

As shown in FIGS. 8 and 11, the valve opening and closing member 42 is provided with a push-up portion 42C that protrudes upward at one end (left end in FIG. 11) of the lever body 42A. It is.

Moreover, as shown in FIG. 11, the valve opening-and-closing member 42 is provided with the pushing-down part 42D in the edge part (right end part in FIG. 11) of the other side of the lever main body 42A, and this push-down part is provided. The lowering part 42D is pushed down by the push-down pin 44 (refer FIG. 6) provided in a part of the lower end part of 4 A of filter units.

In addition, the pushing-down operation | movement to the pushing-down part 42D by the push-down pin 44 of the lower end part of 4A of filter units is based on the raising operation of the filter unit 4A accompanying the raising operation of the front panel 2. As shown in FIG. Release, thereby the normally closed valve 41 is closed.

As illustrated in FIG. 8, the water level detection float 43 is inserted into a central portion where the valve opening and closing member 42 is opened. ) Detects and flashes the water supply lamp 1j of the operation panel unit 1E (see FIGS. 1 and 3) to notify the outside.

As shown in FIG. 8, the water level detection float 43 according to the present embodiment has a floating body 43A on the upper portion as it moves up and down (exactly, to rotate) according to the water level in the tray 7. At the same time, a part of the sensor (magnet in the present embodiment) 43C is provided below the intermediate leg portion 43B. As for the water level detection float 43 of such a structure, the guide shaft 43D provided in the leg part 43B becomes a support point according to the increase and decrease of the water level, and the leg part 43B is a part of 7F of valve operation chambers. It is rotatable along the guide wall 7H provided. That is, the water level detection float 43 is in an upright state when it reaches the highest water level in FIG. 8, but when the water level decreases, the magnet 43C is counterclockwise along the guide wall 7H when the water level decreases. Rotate in the direction.

In addition, the floating body 43A having a specific gravity that is lighter than the water at the top of the water level detection float 43 and the magnet 43C having a higher specific gravity than the water have a weight balance such that the floating body 43A is always drafted. When the water level of the tray 7 falls to a predetermined level (lowest allowable water level) with the fall of the quantity of water accommodated in the water supply tank 3, with the raise of the magnet 43C, the proximity sensor (not shown) (for example, For example, a hall element or the like) is operated to output a detection signal to the control unit 11.

Therefore, when the water supply tank 3 is set in the tank holding portion 7A of the tray 7, the valve opening and closing member 42 is pushed down by the push-down pin 44 by the push-down portion 42D at the other end. It works. As a result, since the valve opening-closing member 42 performs the seesaw operation | movement centering around a rotation support point, the pushing-up part 42C of one side edge part raises and pushes up the pin member 41C. Thereby, since the normally closed valve 41B is opened, it becomes the state which can supply water from the inside of the water supply tank 3 into the tray 7.

(VI) About the support dish feeding mechanism 50:

The support dish feeding mechanism 50 is for receiving the water falling from the filter 4 accommodated in the filter unit 4A, and the interlocking mechanism 20 operates and the filter unit in conjunction with the pulling operation of the front panel 2. After 4A has risen to a predetermined height, when the feed water tank 3 is pulled out from the feed tank chamber S1 of the case body 1A to the tray 7th, in conjunction with the drawing operation of the feed water tank 3 The support dish 8 is made to advance directly under the filter unit 4A, and is to prevent the internal contamination of the humidifier 1 by the sterilizing liquid, the electric trouble, and the like.

The support dish dispensing mechanism 50 of this embodiment is the innermost part of the tray 7 enclosed by the wall 7C, as shown to FIG. 19 and FIG. 20 (A), (B) which are principle diagrams. It consists of the cam surface 51 provided in the wall surface part, and the support plate 8 suspended in the state rotatable by the case main body 1A.

Among them, the cam surface 51 is composed of an inclined surface 51A inclined toward the inner side and a horizontal surface 51B continuously formed from the inclined surface 51A, and the tray 7 and the filter unit 4A are not drawn out. Unless otherwise specified, the coupling pins 52 of the support plate 8 are generally coupled to either of these surfaces.

On the other hand, as shown in Fig. 19, the support plate 8 is a pair of arms 8A having a substantially triangular shape rotatably suspended on both end sides of the filter unit 4A, and a pair of these. A main body 8B is provided between the pair of arms 8A in a state of being integrally fixed to the arm 8A. The arm 8A is provided with a coupling pin 52 to be described later.

The support dish 8 of this embodiment is in the humidification filter chamber S3 which accommodates the filter unit 4A shown in FIG. 1, and the filter unit 4A was fitted from both sides of the filter unit 4A. The lower part is provided below the filter unit 4A, and the main body 8B is rotatably provided around the rotation shaft 8C.

The engaging pin 52 is engaged with the cam surface (the inclined surface 51A and the horizontal surface 51B extending rearward thereof) 51 on the inner side of the tray 7, thereby rotating the operation for feeding the support plate 8. Is done.

Therefore, according to the support dish feeding mechanism 50 of this embodiment, when the front panel 2 is pulled up and the filter unit 4A also moves upwards in association with this, regardless of whether the tray 7 is pulled out or not. By the upward movement of the filter unit 4A, the support plate 8 rotatably installed in the lower portion thereof is pulled up.

Therefore, the coupling pins 52 of the support plate 8 are pushed up to the cam surface 51 of the tray 7 to be released from the standing state, and the coupling pins 52 are not caught anywhere. As shown in (B), it moves upward with the filter unit 4A in the state suspended just below 4A of filter units.

On the other hand, when the tray 7 is inserted to the inner side of the predetermined position, the filter unit 4A is lowered to the lowermost portion, whereby the coupling surface 52 of the support plate 8 is engaged with the cam surface of the tray 7 ( It is pushed up by 51 and is accommodated in the innermost part of the tray 7 in the state in which the main body 8B stood up vertically (refer FIG. 6).

In addition, when the water collected in the support dish 8 returns to the standing state, it returns to the liquid dish 7B of the tray 7 immediately below it. That is, it is collect | recovered by the liquid dish 7B of the tray 7, and can be reused. Thereby, it is comprised so that economic effect may be acquired.

In addition, in order to lower the filter unit 4A to the lowest part, the operation | work which lowers the front panel 2 by the interlocking mechanism 20 is necessary. By the way, even if the filter unit 4A can be pushed down by hand or the like without lowering the tray 7, the tray 7 to which the coupling pin 52 of the support plate 8 is engaged is engaged. Is not present, the support dish 8 stands vertically and does not retract directly from underneath the filter unit 4A, and even if the disinfecting liquid falls from the filter 4 housed in the filter unit 4A. It can be received in the dish (8).

(VII) For the first lock mechanism 60A:

The first lock mechanism 60A of the present embodiment prevents the filter unit 4A from being raised any longer at the portion where the filter unit 4A is raised to the uppermost part, and forcibly filters the filter unit 4A. Even if it tries to push down, the filter unit 4A cannot be dropped unless the locked state of the 2nd lock mechanism 60B mentioned later is released and the front panel 2 is not dropped manually. In the case where the filter unit 4A is raised to the uppermost portion, it is also possible to avoid falling naturally due to the weight of the filter unit 4A.

In this embodiment, as shown in FIG. 15, at least in the area | region right rather than the line (neutral line) L connecting the rotating shaft 22A of the triangular plate 22, and the connection shaft 23B of the arm 23. As shown in FIG. After the connecting shaft 23A of the arm 23 reaches, in other words, after passing through the neutral point, the right edge portion (or may be the right edge portion of the arm 23) to the rightmost position Rotate Then, since the hook 24 mentioned later cannot reach the lowest part 2B 'of the groove | channel 2B, and cannot descent more than that, it will not be able to rotate further to the right side, and the triangular plate 22 and the arm 23 will not be able to rotate further. ) Becomes the locked state (final locked state) in the final position. Further, even if the hook 24 as described above reaches the bottom of the groove 2B and the final lock state for the double safety (double safe) is performed, the second lock mechanism shown in FIG. 18 will be described later in detail. By the locking operation of 60B, the triangular plate 22 and the arm 23 are in a simple primary lock state. In addition, from this temporary locked state, when the front panel 2 is raised by hand, it will be in the final locked state mentioned above.

Specifically, the connecting shaft 23A of the arm 23 reaches the region to the right of at least the line L connecting the rotating shaft 22A of the triangular plate 22 and the connecting shaft 23B of the arm 23. At one point in time, as shown in FIG. 15, the hook 24 having the lowermost part 2B '(see FIG. 15) of the groove 2B of the front panel 2 protruding from the front surface of the case body 1A. ), You will not be able to rise above this level. Thus, the triangular plate 22 constituting a part of the interlock mechanism 20 (connected with the connecting member 21 to which the rotating shaft 21A is coupled to the rotating bearing 2A of the front panel 2 (see FIG. 6)). ) And the arm 23 also cannot rotate in the rightward direction at least at a portion of the predetermined position beyond the neutral line L, thereby becoming a locked state (first locked state).

(XI) For the second lock mechanism 60B:

The second lock mechanism 60B prevents the front panel 2 from falling down when the water is supplied to the water supply tank 3 (or cleaning of the liquid dish 7B or the filter 4). It is for making an entrance work safe, and it operates when the front panel 2 is raised to a predetermined raise position, and it locks the front panel 2 temporarily at the raise position.

When the 2nd lock mechanism 60B of this embodiment raises the front panel 2 to the state shown in FIG. 15, the rotating bearing 2A provided in the lower part of the inner side surface of the front panel 2 (FIG. 6). As shown in FIG. 18, the connecting member 21 (refer FIG. 17) which protruded and provided the rotating shaft 21A which couple | bonds with and rises to the lock chamber S7 of the upper part of feed water tank chamber S1 is referred to. It is coupled to the installed leaf spring (13).

Specifically, in Fig. 18, the leaf spring 13 is pivotally supported in a state where the base is fixedly installed at the upper right corner of the lock chamber S7, and the convex projecting upward from the middle to the tip. While the portion 11A is formed, the portion from the intermediate portion where the convex portion 13A is formed to the tip portion has an elastic force directed upward. On the other hand, in the connecting member 21, the recessed part 21B along the convex part 13A of the leaf spring 13 is formed in the bottom part.

Therefore, when the front panel 2 raises to a predetermined position, and the connecting member 21 rotates to a predetermined angle in the clockwise direction with this raising operation, the recess 21B enters the convex portion 13A. Since it fits in, a temporary lock state is performed. In order to release the locked state, the front panel 2 may be lowered by a force greater than the elastic force of the leaf spring 13 to push down the leaf spring 13 to release the locked state.

(VIII) For Damper Mechanism 70:

As shown in FIG. 16, the damper mechanism 70 of this embodiment is a damper member 71 (refer FIG. 17) fixedly installed in the substantially central part side of the triangular plate 22, and this damper member 71 A sector gear 72 is provided, which is provided with a circular arc-shaped external toothed portion 72A meshing with the gear 71A provided therein, and is rotatably assembled to the rotation shaft 22A.

The damper member 71 is filled with damper oil, and even if a large rotational force acts on the gear 71A, the rotational force is attenuated using the viscosity of the damper oil, and thus the front panel 2 and the filter unit 4A. It can prevent the rapid descent operation of.

Although the center gear 72 is rotatably assembled to the rotary shaft 22A of the triangular plate 22, two places 72B and 72C on the outer circumferential side where the external teeth 72A are provided are provided in the case body. It is fixedly attached to 1A by screws etc., and is floating to the case main body 1A.

Therefore, according to the damper mechanism 70 of this embodiment, when pulling up the front panel 2 after raising the front panel 2, the front panel 2 is dropped by an excessive force, or the filter unit ( Even if 4A) is forcibly pressed in, the rapid descent operation of the front panel 2 and the filter unit 4A can be braked by the damper force of the damper member 71. FIG. Therefore, it is possible to effectively prevent the front panel 2 and the filter unit 4A and the case body 1A from being damaged by the rapid dropping operation of the front panel 2 and the filter unit 4A.

(IX) For the gear engagement mechanism 81:

As shown in FIG. 21, the gear engaging mechanism 81 is provided in the filter motor 81A of the case body 1A when the filter unit 4A is taken out or stored in the humidification filter chamber S3. It is for adjusting the engagement state of the drive gear 81B and the driven gear 4E for rotational operation of the filter 4 provided in the filter holder 4D (refer FIG. 1) of the filter unit 4A. In other words, as shown in Fig. 21, the gear engagement mechanism 81 forms a small gap (gap) δ between the filter unit 4A and the filter holder 4D, thereby absorbing backlash. It is to plan. In addition, in the gear engagement mechanism 81 of this embodiment, as shown in FIG. 1 and FIG. 21, the lower side is inclined to the front side by the angle (theta) with respect to the case main body 1A.

Therefore, according to this gear engagement mechanism 81, when moving the filter unit 4A up and down, the fitting operation | movement of the filter unit 4A and the filter holder 4D provided for installing the driven gear 4E is performed. This can be done as follows.

That is, when raising the filter unit 4A, the filter unit 4A is lifted up first and the filter holder 4D is lifted up a little later, so that the drive gear (on the drive motor side) by the driven gear 4E ( 81B) is released smoothly. On the other hand, when lowering the filter unit 4A, after engagement of the driven gear 4E and the drive gear 81B, the filter unit 4A will go further down and will be isolate | separated from the filter holder 4D. That is, when descending, the driven gear 4E and the drive gear 81B provided in the filter holder 4D inside the filter unit 4A will always be in engagement, and the filter unit 4A for moving up and down ). For that purpose, the clearance (gap) (delta) for separating is formed. By configuring in this way, since the presence of the filter unit 4A does not need to be considered in transmission of a gear, reliable engagement of the driven gear 4E and the drive gear 81B is attained.

(VIII) For the normally closed mechanism 82:

The normally closed mechanism 82 forcibly opens the closing lid 1G from the humidification filter chamber S3 accommodating the filter unit 4A provided on the upper surface of the case body 1A, and pulls out the filter unit 4A.

Diode) is installed.

According to this liquid level lighting device 110, as the light source 9, the LED illuminates the water inside the water supply tank 3 in a specific color (here, for example, blue), so that the water in the water supply tank 3 has a specific color. It is colored and floated (for example, blue), and this water can be easily confirmed from the outside through the viewing window 2C (refer to FIG. 4 (A)) provided in the front panel 2.

For (XIV) Auxiliary Suction Apparatus 84:

The auxiliary suction mechanism 84 introduces air from a place different from the air suction port 1B on the back side, so that even if the air passing through the filter 4 cannot be sufficiently deodorized by an ozone generator, Dilute the concentration to the extent that you don't care and send it out.

In the auxiliary suction mechanism 84 of the present embodiment, air is introduced from the outside toward the blowing fan 5 to a part of the case body 1A other than the installation portion of the air filter 10 that faces the filter 4. An opening (secondary air inlet) 84A (see Fig. 2) is provided. By this auxiliary suction mechanism 84, air without an unpleasant odor is flown from a place separate from the main air suction port 1B on the back side through a flow path other than the flow path from the filter 4 to the blowing fan 5. It can be introduced additionally.

Moreover, you may comprise so that the flow path which guides the air introduce | transduced from the place different from the air suction port 1B of the back side to the humidification filter 4 as this auxiliary suction mechanism 84 may be added. In this way, even if there is only the installation space where the back side approaches the wall etc. for the convenience of an installation place, the various functions which the humidifier 1 provided with the filter apparatus 90 of this invention can fully exhibit are exhibited. Therefore, the degree of freedom as an installation place also becomes high.

(VII) For safety mechanism 85:

When the interlock mechanism 20 operates, the filter unit 4A rises with the pulling-up operation of the front panel 2, and the closing cover 1G of the case main body 1A opens, the safety mechanism 85 will open this. The opening operation is detected to automatically stop the operation of the rotation driving motor of the filter 4 to ensure safety during the take-out operation of the tray 7.

As a result, as shown in FIG. 26, when the filter 4 is in the tensioned state, the driven shaft 93 positioned at the first position S1 moves to the contracted position S2. That is, the filter main body 91 contracts by the driven shaft 93 moving by the stroke (DELTA) S1. Thereby, since the filter 4 can be kept loose, the filter 4 can be easily removed from the filter main body 91 by removing from the drive shaft 92 which the filter 4 catches.

In addition, the filter 4 after simply removing it from the filter main body 91 can be installed easily also when returning to the filter main body 91 after cleaning or an exchange operation | movement. In other words, the filter 4 is arranged in the longitudinal direction (arranged so that the opening portion faces in the horizontal direction), and the opening is passed through the filter main body 91 in the contracted state while being caught by the drive shaft 92. Therefore, it is also possible to prevent soiling of hands, clothes, and the like at the time of attaching and detaching the filter.

Moreover, according to this embodiment, the driven shaft 93 always immersed in the liquid dish 7B together with the lower part of the filter 4 is in the bottom part between the blade part 93B and the side blade part 93B. Even when water is collected, when the filter main body 91 is taken out, immediately after rising from the liquid level at the liquid plate 7B of the tray 7, the through hole for water (bacterial liquid) drainage drilled in the central shaft portion 93A ( Water gathered from 93C) starts to overflow into the tray 7. Therefore, after raising the filter main body 91 upward from the tray, water (sterilization liquid) does not overflow from the filter holder 4D, and it is possible to avoid damaging the inside of the humidifier.

In addition, this invention is not limited to said embodiment, It can implement in various forms in the range which does not deviate from the summary. That is, in this embodiment, although it applied to the humidifier provided with a filter apparatus, it is also applicable also to the apparatus provided with the filter apparatus of this invention to various apparatuses, such as a cold air blower and a blower, for example.

As the filter device of the present invention can easily attach and detach a filter without being polluted by a person, clothes, the convenience of usability improves easily, and even an elderly person or a woman can clean and replace a filter neatly It is convenient.
