Description

  The present invention relates to a humidifier that can easily take out a water supply tank, a liquid dish, and a filter, and can easily supply water to the water supply tank, and clean the liquid dish and the filter.

Conventionally, for example, a humidifier described in Patent Document 1 is known.
That is, as shown in FIG. 22 and FIG. 23, the humidifier 100 includes a main frame body 101 having an air outlet 107 formed on the front surface, and a blower device 102 mounted in the main frame body 101 behind the air outlet 107. The water tank 103 detachably stored in the lower part inside the main frame 101, the belt-like filter 104 whose lower part is immersed in the water W stored in the water tank 103, and the vertical direction so as to rotate the belt-like filter 104 to the inner surface. There is known a structure having a lid body 105 that is installed and supported on the rear side of the main frame body 101 so that the rear opening of the main frame body 101 can be opened and closed. Further, the lid 105 is formed with an air inlet 106 in which a belt-like filter 104 is arranged in the vicinity. The main frame 101 and the lid 105 form a humidifier casing, and the belt-like filter A ventilation path provided from the air inlet 106 to the air outlet 107 through 104 is formed in the housing.

Such a humidifier 100 rotates the belt-like filter 104 in a state where it is immersed in the water W of the water tank 103, and sucks air from the air inlet 106 and blows air from the air outlet 107 by driving the air blower 102. ing.
The air blown out from the air outlet 107 passes through the water-containing belt-like filter 104 in the vicinity of the air inlet 106 and is evaporated from the belt-like filter 104 and humidified by the latent heat of vaporization of water. By blowing out the humidified air from the outlet 107, the surrounding space of the humidifier 100 is humidified.
Further, in consideration of use in winter, the humidifier 100 has a heating element 108 arranged in the blower 102 so as to protrude into the air passage, and even if the intake humidity from the intake port 106 is low, The heater 108 heats the air in the air passage to increase the amount of saturated water vapor, and air with high humidity can be obtained.

  By the way, in the humidifier having such a configuration, as shown in FIG. 24, a water supply body 110 that can be pulled out is attached to the opening formed in the right side portion of the main frame 101. Further, a water supply hole is formed in the lid 111 portion of the water supply body 110 with respect to the inner outlet of the main frame 101, and water is supplied from the water supply body 110 to the water tank 103.

  However, in the humidifier configured as described above, when the water supply operation is performed, the transported water is replenished to the water tank 103 from the relatively narrow water supply body 110 by a sprinkler or the like. There is a risk of spilling water when replenishing from the supply body 110. Further, since the water tank 103 cannot be easily taken out, the bottom of the water tank 103 cannot be cleaned.

  Further, as a humidifier equipped with such a humidifying filter, for example, a humidifier equipped with a sterilizing electrode for sterilizing water in the water tank in a water tank in which the humidifying filter is installed is known.

  This type of humidifier has an air suction port and a discharge port, and an outer case provided with a water tank for storing water supplied from a water supply tank at a predetermined level at the bottom, a humidifying filter installed in the water tank, And a blower that vaporizes water that has been blown to the humidification filter and penetrated into the humidification filter, and is provided with a sterilization electrode that performs a sterilization action of water in the water tank at an appropriate position of the water tank.

  Unlike the one described in Patent Document 1, the humidifier described above uses a cartridge-type water supply tank, so that it is easy to supply water, and there is no problem in that respect. However, in general, when cleaning the clog of the humidification filter or replacing the humidification filter with a new one, the water tank or water supply path where the humidification filter is installed is exposed and installed in this water tank or water supply path. There was a concern that the customer touches the disinfected electrode. Usually, because the electrode for sterilization is made of a thin metal plate such as stainless steel or titanium alloy, if the customer touches the sterilization electrode by mistake, there is a concern that the finger may be injured. Further, when the humidifying filter is brought into contact with the sterilization electrode, there is a concern that the sterilization electrode may be damaged.

  Therefore, a humidifier has been proposed in which electrodes such as a sterilization electrode and a water level detection electrode are installed in a water tank for storing water for humidification so that the safety of the humidifier can be improved (for example, Patent Documents). 2).

That is, for example, as shown in FIGS. 25 and 26, the case has an air suction port 201 and a discharge port 202, and a water tank 203 for storing water supplied from the water supply tank 210 at a predetermined level at the bottom. A main body 200A, a detachable panel 220 that is detachably attached to the case main body 200A, a humidifying filter 230 installed in the water supply tank 210, and a blower that vaporizes water that is blown to the humidifying filter 230 and permeates the humidifying filter. 240, a humidifier in which the humidifying filter 230 is detachable from the open surface Z (see FIG. 26) of the case body 200A by removing the detachable panel 220 from the case body 200A. A sterilization electrode 211 for sterilizing the water in the water supply tank 210 is provided at an appropriate position of the water supply tank 210, and air permeability is provided between the sterilization electrode 211 and the open surface Z of the case body 200A. It is the structure which provided the protection member 240 (refer FIG. 25) which has.
In the figure, reference numeral 250 denotes an air purification filter, 260 denotes an operation unit, 270 denotes a controller, and 280 denotes a fan.

When the tray 7 is stored in the lower part of the case main body 1A, the handle 7G can be stored so as to be buried under the bottom of the tray 7 and can be prevented from protruding from the front side. ing. Further, when the tray 7 is pulled out of the case body 1A, if the handle 7G is rotated upward to a predetermined angle around the rotation fulcrum 7D, a temporary standing state is maintained and the water supply tank 3 is maintained. A pin-like stopper 7E is provided on the side surface of the tray 7 so as not to obstruct the take-out operation.

  In the tank holding portion 7A, as shown in FIG. 7, a valve operation chamber 7F in which a valve opening / closing member 42 for opening a normally closed valve 41, which will be described later, is installed is formed at the center. In the valve operation chamber 7F, when the water supply tank 3 is set on the tray 7, a lower portion of the normally closed valve 41 is disposed, and a valve opening / closing member 42 and a float member 43 are attached.

  In the liquid dish 7B, a sterilizing liquid is generated and stored from tap water sent out from the water supply tank 3, and any lower region of the endless belt-like filter 4 that is rotationally driven at an appropriate timing is provided. It is always immersed in this sterilization solution.

  Therefore, although details will be described later, it is assumed that the interlocking mechanism 20 operates in conjunction with the lifting operation of the front panel 2 and the filter unit 4A is pulled up to a predetermined height. Then, the saucer 8 attached to the lower part of the filter unit 4A rises in the same manner, and the saucer 8 also rotates downward along with this. Thereafter, as shown in FIG. 12, when the ascending position reaches a position higher than the tray 7, the engaging operation with the tray 7 that has pushed the tray 8 upward is released. For this reason, the saucer 8 advances just below the filter unit 4A and stops in a horizontal state.

  As a result, water dripping from the filter 4 accommodated in the filter unit 4A can be received by the receiving tray 8 immediately below, so that even if the tray 7 is not pulled out, the liquid can be separated from the tray 7 by moving upward. It is possible to avoid the droplets dropping from the filter 4 away from the surface from being scattered on the liquid surface of the liquid dish 7B of the tray 7. As a result, it is possible to prevent the disinfecting liquid from splashing at a predetermined position inside the case main body 1A and causing various inconveniences such as internal contamination, conductor corrosion, or short circuit.

Further, from the water supply tank chamber S ₁ of the case main body 1A, the water supply tank 3 per tray 7 is pulled out, as in the case where the filter unit 4A is raised, engages operation of a tray 7 which had pushed up the pan 8 upwards The tray 8 is released from the above. As a result, in conjunction with the pulling-out operation of the water supply tank 3, the receiving tray 8 also advances immediately below the filter unit 4A and stabilizes in a horizontal state. Accordingly, in this case as well, water dripping from the filter 4 accommodated in the filter unit 4A can be received by the tray 8 and the disinfecting liquid is scattered at a predetermined position inside the case main body 1A. It is possible to prevent the occurrence of internal contamination, conductor corrosion, or short circuit.

  The light source 9 constitutes a lamp for visually confirming the amount of water that illuminates the water in the water supply tank 3 with a specific color. The light source 9 of this embodiment is installed in the back side of the water supply tank 3, as shown in FIG. 6, and is comprised by LED (Light Emitting Diode). The light source 9 of the present 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 urged to confirm the amount of remaining water in the tank from the outside through the visual recognition window 2 </ b> C provided on the front panel 2.

Air filter 10, as shown in FIG. 1, is intended for purifying the air before passing through the filter 4 is taken from the outside, the rear side of the inner case body 1A that faces the humidifying filter chamber S _3, the air inlet Opposing to the mouth 1B.

  As shown in FIG. 13, the control unit 11 includes various electronic components in the electric system that perform various controls in the control box 11 </ b> A at the front portion where the lower portion of the case body 1 </ b> A is exposed as the front panel 2 is pulled up. And is unitized (or modularized).

In particular, in the control unit 11, so that such signal lines and power lines to achieve a connection, such as the various sensors and the control unit 11 inside the CPU provided inside the humidifier 1 is not exposed in a bare state to the internal control chamber S _5, All the electric wires are wired from the back surface of the partition plate to the control box 11A.

(I) About interlocking mechanism 20:
The interlocking mechanism 20 can supply water (tap water) to the water supply tank 3 and clean the liquid dish 7B (in this embodiment, the filter 4 can also be cleaned or replaced. Therefore, the filter unit 4 </ b> A can be pulled out in conjunction with the operation of pulling up the front panel 2. As described above, when the water supply tank 3 is replenished with water (tap water), the filter unit 4A is configured to be pulled out (exactly pulled up). On the other hand, the lower part of the filter unit 4A enters the liquid plate 7B of the tray 7, and this becomes an obstacle unless the lower part of the filter unit 4A is lifted upward. It is because it cannot be pulled out.

  Thus, in particular, in the interlocking mechanism 20 of the present invention, the water supply tank 3 is not pulled up and taken out as in the prior art, but is taken out by being pulled out in the horizontal direction so that water can be replenished. The take-out operation of the water supply tank 3 can be easily performed. In the present embodiment, when the front panel 2 is pulled up, the fingertip can be inserted into the front central portion of the base body BS as shown in FIG. An opening BS1 is provided.

Still further, this interlocking mechanism 20, the extraction (withdrawal) can upper portion of the filter unit 4A is been projected from the humidifying filter chamber S ₃ of the inner case body 1A. As a result, as described above, the filter 4 can be cleaned or replaced at the same time.

  The interlocking mechanism 20 is configured so that the filter unit 4A, on which the filter 4 is stretched, rises in conjunction with the operation of pulling up the front panel 2 from the case main body 1A, and the upper surface of the case main body 1A is raised by the ascent operation of the filter unit 4A. The installed closure lid 1G is pushed up and opened, and the upper part of the filter unit 4A (filter 4) protrudes from the upper surface of the case body.

  As shown in FIG. 4B, the interlock mechanism 20 of the present embodiment is a slide provided between the case body 1A and the front panel 2 in order to guide the front panel 2 to be movable up and down relative to the case body 1A. As shown in FIG. 14, the guide means 20 </ b> A and lifting force transmission means 20 </ b> B for lifting and lowering the filter unit 4 </ b> A by transmitting the lifting operation of the front panel 2 are provided.

  Among these, the slide guide means 20 </ b> A constituting a part of the interlocking mechanism 20 of the present embodiment is installed between the case body 1 </ b> A and the front panel 2. Specifically, as shown in FIG. 6, the slide guide means 20A is disposed at the lower part on the inner surface side of the front panel 2 by the cooperative action with the rotary bearing 2A (see FIG. 4B) described above. A guide groove 2B is formed along the vertical direction as a guide for moving the panel 2 in the vertical direction. On the other hand, to correspond to this, a claw 24 (see FIG. 4B) that engages with the guide groove 2B is projected from both ends in the width (Y) direction of the case body 1A.

  On the other hand, the lifting force transmitting means 20B constituting the remaining part of the interlocking mechanism 20 of the present embodiment is installed between the front panel 2 and the filter unit 4A, and is mainly interlocked with the lifting operation of the front panel 2. The link mechanism rotates. Specifically, as shown in FIGS. 14 and 15, the lifting force transmitting means 20B is pivotally connected to the pivot bearing 2A of the front panel 2 (see FIG. 4B). A connecting member 21 (see FIG. 14) having a shaft 21A attached in the width (Y) direction of the case body 1A, and a pair of triangular plates 22 fixed to both ends of the connecting member 21 by screws or the like so as not to rotate. The arm 23 is connected to a connecting shaft 23A provided at the upper corner of the triangular plate 22 in a state where one end is rotatable, and the multi-end connecting shaft 23B is connected to the filter unit 4A in a rotatable state. And. One set of the lifting force transmission means 20B is installed on each of the left and right side surfaces of the case body 1A, and the lifting force transmission means 20B on both the left and right sides are simultaneously operated by the connecting member 21.

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

  Further, between the triangular plate 22 and the case main body 1A, as shown in FIG. 16, when the front panel 2 is pulled down after the front panel 2 is pulled up, the front panel 2 and the filter unit 4A are rapidly moved. A damper mechanism 70 for preventing the lowering operation is provided. The specific configuration of the damper mechanism 70 of this embodiment will be described in detail later.

  Therefore, according to the interlocking mechanism 20 of the present embodiment, a finger of a hand or the like is inserted into the opening BS1 of the base body BS to grip the lower portion of the front panel 2 and lifted upward. Then, the rotating shaft 21A pivotally supported by the rotating bearing 2A at the lower part of the front panel 2 rises with the raising operation of the front panel 2, and the raising operation at this time is configured by a link mechanism via the connecting member 21. The left and right lifting force transmitting means 20B, as shown in FIG. 14, transmits to the filter unit 4A to perform the ascending operation. 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 body 1A.

  When it finally rises to the uppermost position, the guide claw 24 (see FIG. 4) of the case main body 1A engages with the lowermost portion of the guide groove 2B of the front panel 2, and the leaf spring 13 (first step) of the case main body 1A 2 lock mechanism 60B (refer to FIG. 18) is fitted into a leaf spring member having a spring property so that the locked state is temporarily maintained. Therefore, even if the front panel 2 is not held by hand, it can be lowered. It remains as it is.

Thus, since the tray 7 equipped with a water supply tank 3 from the tank chamber S ₁ for opening by an increase of the front panel 2 is enabled drawer, allows replenishment of water into the water supply tank 3. At the same time, the filter unit 4A can be pulled out and the filter 4 can be cleaned or replaced.

  On the other hand, in order to lower the front panel 2, the locked state may be released. By releasing the lock, the front panel 2 and the filter unit 4A are lowered by their own weights, but the sudden lowering operation is suppressed by the damper mechanism 70 and the lowering operation is performed slowly, so that impact is avoided and safety is ensured. Is also secured.

Further, the interlock mechanism 20 is provided with a first lock mechanism 60A and a second lock mechanism 60B as shown in FIGS.
Among these, the first lock mechanism 60A, which will be described in detail later, operates the interlocking mechanism 20 to raise the filter unit 4A as the front panel 2 is pulled up, and the filter 4 from the closed lid 1G opened in the case body 1A. This prevents the single descent operation in which only the filter unit 4A descends after a part of the projection protrudes.

  On the other hand, as will be described in detail later, the second lock means 60B prevents the front panel 2 from descending when water is supplied to the water supply tank 3 (or when the liquid dish 7B and the filter 4 are cleaned). The tray 7 can be safely moved in and out, and is activated when the front panel 2 is pulled up to a predetermined raised position, and the front panel 2 is temporarily locked at the raised position. Yes.

(II) Regarding the electrode retracting mechanism 30:
Electrode retracting mechanism 30, by raising the front panel 2, this from the water supply tank chamber S ₁ of the lower front of the opened case body 1A from the shield state (front side), when pulling out the per tray 7 water tank 3 This is intended not to obstruct the operation of pulling out the water supply tank 3. In the present invention, the electrode 6 (see FIG. 9 and FIG. 10) that has entered the liquid dish 7B of the tray 7 in the immersed state is retracted upward by the electrode retracting mechanism 30.

  As shown in FIGS. 9 and 10, the electrode retracting mechanism 30 of the present embodiment is installed in a state of being suspended from the lower end of the filter unit 4 </ b> A on which the filter 4 is stretched. That is, the electrode retracting mechanism 30 according to the present embodiment is configured by a simple structure in which the electrode 6 is physically suspended below the filter unit 4A, and the electrode 6 is also interlocked with the lifting operation of the filter unit 4A. Since it moves up and down in the same way, if the filter unit 4A is raised, the electrode 6 can be retracted from the immersion state in the liquid dish 7B.

  Accordingly, when the front panel 2 is pulled up from the case main body 1A, the filter unit 4A is lifted in conjunction with the operation of pulling up the front panel 2, and along with this, the filter unit 4B of the tray 7 is immersed in the liquid dish 7B. The fungus electrode 6 also rises. Finally, when the filter unit 4A is raised to a predetermined height, the sterilization electrode 6 is also raised to at least a height that can exceed the wall 7C provided around the tray 7. Finally, the lowermost part of the sterilization electrode 6 reaches a position where the height is higher than the wall 7C of the tray 7. Therefore, the tray 7 can be pulled out in the horizontal direction without being locked to the sterilization electrode 6 when the water supply tank 3 is taken out, for example.

(III) Regarding the valve opening / closing mechanism 40:
As shown in FIGS. 7, 8 and 11, the valve opening / closing mechanism 40 automatically closes when the water supply tank 3 is lifted and removed from the tray 7, and automatically when the water supply tank 3 is returned to a predetermined position on the tray 7. This is for starting the water supply operation. Further, the valve opening / closing mechanism 40 is provided with a water level detection float 43 that constitutes a water detection means, and a magnet and proximity sensor (not shown) that are not shown, and outputs a detection signal to the control unit 11 for the water level. At the same time, the control unit 11 activates the water supply blinking lamp 1j of the operation unit 1E when the water level is equal to or lower than a predetermined level. Illuminate the liquid surface for arousal).

  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 and a valve that opens the normally closed valve 41 in the valve operation chamber 7F of the tray 7 shown in FIGS. An opening / closing member 42 and a water level detection float 43 that detects and displays the water level are disposed.

  As shown in FIG. 7, the normally closed valve 41 includes a screw lid 41A screwed into a water supply port 3A provided in the lower portion of the water supply tank 3, and a substantially dish-shaped valve installed at the center of the screw lid 41A. A plug body 41B and a pin member 41C, which is installed in a hole at the center of the screw lid 41A so as to be vertically movable and has a plug body 41B integrally fixed to the upper part thereof. A tension spring (not shown) is interposed between the screw lid 41A and the plug body 41B, 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, as shown in FIG. 11, the valve opening / closing member 42 has a substantially square frame housed in the valve operation chamber 7F, and both ends of the valve opening / closing member 42 have a rotation shaft 42B provided at an intermediate portion as a rotation fulcrum. A lever body 42A that can be operated seesaw up and down, and a water level detection float 43 for water level detection that is loosely inserted with respect to the lever body 42A in the vicinity of the pivot shaft 42B of the lever body 42A. It is equipped with. In this embodiment, the water level detection float 43 is loosely inserted in the center of the lever main body 42A. However, the present invention is not particularly limited to this configuration. For example, the water level detection float 43 may be provided near the lever main body 42A. .

  As shown in FIGS. 8 and 11, the valve opening / closing member 42 is formed with a push-up portion 42 </ b> C protruding upward at one end portion (left end portion in FIG. 11) of the lever main body 42 </ b> A.

Further, as shown in FIG. 11, the valve opening / closing member 42 is formed with a pressing portion 42D at the other end portion (the right end portion in FIG. 11) of the lever main body 42A. The pressing portion 42D serves as a filter unit. It is pushed downward by a push pin 44 (see FIG. 6) provided at a part of the lower end of 4A.
Note that the pressing operation to the pressing portion 42D by the pressing pin 44 at the lower end of the filter unit 4A is released by the lifting operation of the filter unit 4A accompanying the lifting operation of the front panel 2, and thereafter the normally closed valve 41 is closed. Is done.

  As shown in FIG. 8, the water level detection float 43 is inserted in the central portion where the valve opening / closing member 42 is opened, and the control unit 11 detects when the water in the tray 7 drops to the set minimum water level. Then, the water supply lamp 1j of the operation panel unit 1E (see FIGS. 1 and 3) is blinked to notify the outside.

  As shown in FIG. 8, the water level detection float 43 of the present embodiment has a floating body 43 </ b> A at the top so as to move up and down according to the water level in the tray 7 (more precisely, rotate) and an intermediate leg. A part (a magnet in the present embodiment) 43C of the sensor is provided in the lower part via the part 43B. In the water level detection float 43 having such a configuration, the guide shaft 43D provided in the leg portion 43B serves as a fulcrum according to the increase or decrease of the water level, and the leg portion 43B extends along the guide wall 7H provided in a part of the valve operation chamber 7F. It can be turned. That is, in FIG. 8, the water level detection float 43 becomes upright when the highest water level is reached, but when the water level falls, the magnet 43C rotates counterclockwise along the guide wall 7H as the water level falls.

  Note that the floating body 43A having a specific gravity lighter than the water above the water level detection float 43 and the magnet 43C having a specific gravity heavier than water are balanced in weight so that the floating body 43A is always drafted. When the water level of the tray 7 decreases to a predetermined level (minimum allowable water level) as the amount of stored water decreases, a proximity sensor (for example, a Hall element) (not shown) is activated as the magnet 43C rises. A detection signal is output to the control unit 11.

  Accordingly, when the water supply tank 3 is set in the tank holding portion 7 </ b> A of the tray 7, the valve opening / closing member 42 is pushed down by the pressing pin 44 at the pressing portion 42 </ b> D at the other end. As a result, the valve opening / closing member 42 performs a seesaw operation around the rotation fulcrum, so that the push-up portion 42C at one end is raised to push up the pin member 41C. Accordingly, the normally closed valve 41B is opened, so that water can be supplied from the inside of the water supply tank 3 into the tray 7.

(VI) Regarding the tray feeding mechanism 50:
The tray feeding mechanism 50 is for receiving water dripping from the filter 4 accommodated in the filter unit 4A. The interlocking mechanism 20 is activated, and the filter unit 4A is moved to a predetermined height in conjunction with the pulling operation of the front panel 2. after rising in summary, from a water supply tank chamber S ₁ of the case main body 1A, the tray 7 by the water supply tank 3 is pulled out, in conjunction with the pull-out operation of the water supply tank 3, pan 8 immediately below the filter unit 4A moves forward In this way, the inside of the humidifier 1 due to the sterilizing liquid is prevented from being contaminated or electrically troubled.

The tray feeding mechanism 50 of the present embodiment is provided on the innermost wall surface portion of the tray 7 surrounded by the wall 7C, as shown in FIGS. It is comprised by the cam surface 51 and the saucer 8 suspended so that rotation to the case main body 1A was possible.
Of these, the cam surface 51 is composed of an inclined surface 51A inclined toward the inner part and a horizontal surface 51B provided continuously from the inclined surface 51A. Normally, unless the tray 7 and the filter unit 4A are pulled out, The engagement pin 52 of the tray 8 is engaged with any one of these surfaces.

  On the other hand, as shown in FIG. 19, the tray 8 is integrally fixed to a pair of arms 8A having a substantially triangular shape that is pivotably suspended at both ends of the filter unit 4A, and the pair of arms 8A. And a main body 8B spanned between the pair of arms 8A. The arm 8A is provided with an engagement pin 52 described later.

Pan 8 of the present embodiment, in a humidified filter chamber S ₃ which accommodates the filter unit 4A shown in FIG. 1, in a state as the both sides of the filter unit 4A sandwich the filter unit 4A, attached to the lower filter unit 4A The main body 8B is rotatably installed around the rotation shaft 8C.

  The engagement pin 52 engages with the cam surface (the inclined surface 51 </ b> A and the horizontal surface 51 </ b> B extending rearward) 51 on the back side of the tray 7, thereby performing a rotation operation for the feeding operation of the tray 8.

  Therefore, according to the tray feeding mechanism 50 of the present embodiment, when the front panel 2 is pulled up and the filter unit 4A is also moved upward in conjunction therewith, the filter unit regardless of whether or not the tray 7 is pulled out. The saucer 8 pivotally attached to the lower part by the upward movement of 4A is pulled up.

  Accordingly, the engaging pin 52 of the tray 8 is released from the standing state by being pushed up by the cam surface 51 of the tray 7 by being engaged, and the engaging pin 52 is not locked anywhere. As shown in FIG. 20B, the filter unit 4A moves upward together with the filter unit 4A in a state of being hung directly below the filter unit 4A.

On the other hand, when the tray 7 is inserted to the back of the predetermined position, the filter unit 4A is lowered to the lowermost position, so that the engaging pin 52 of the tray 8 is pushed up to the cam surface 51 of the tray 7 while being engaged. The main body 8B is stored in the innermost part of the tray 7 in a vertically upright state (see FIG. 6).
The water collected in the tray 8 is returned to the liquid tray 7B of the tray 7 immediately below when returning to the standing state. That is, it is collected in the liquid dish 7B of the tray 7 and can be reused. Thereby, it is comprised so that an economic effect may be acquired.

  In order to lower the filter unit 4 </ b> A to the lowest position, it is necessary to lower the front panel 2 by the interlocking mechanism 20. However, even if the filter unit 4A can be forcibly pushed down and lowered to the lowermost part without accommodating the tray 7 by any means, the tray 7 to which the engaging pin 52 of the tray 8 is engaged can be obtained. When it does not exist, the receiving tray 8 stands vertically and does not retract from directly below the filter unit 4A, and even if the sterilizing liquid drops from the filter 4 stored in the filter unit 4A, it can be received by the receiving tray 8. it can.

(VII) Regarding the first lock mechanism 60A:
The first lock mechanism 60A of the present embodiment prevents the filter unit 4A from being raised any more when the filter unit 4A is raised to the top, and forcibly depresses and lowers the filter unit 4A by any chance. Even so, the filter unit 4A cannot be lowered unless the lock state of the second lock mechanism 60B described later is released and the front panel 2 is lowered by hand. Further, when the filter unit 4A is left as it is up to the top, it can be avoided that the filter unit 4A naturally descends due to its own weight.

  In this embodiment, as shown in FIG. 15, the connecting shaft 23 </ b> A of the arm 23 reaches the right region from a line (neutral line) L connecting at least the rotating shaft 22 </ b> A of the triangular plate 22 and the connecting shaft 23 </ b> B of the arm 23. In other words, in other words, the right edge (or the right edge of the arm 23) of the triangular plate 22 after passing through the neutral point rotates to the rightmost position. Then, since the later-described pawl 24 reaches the lowermost part 2B ′ of the groove 2B and cannot be lowered further, it cannot be rotated further to the right, and the triangular plate 22 and the arm 23 are locked in the final position ( Final lock state). Further, even before the claw 24 as described above reaches the lowermost part of the groove 2B and the final locked state for double safety (double safe) is performed, details will be described later. By the locking operation of the two-lock mechanism 60B, the triangular plate 22 and the arm 23 are in a simple primary locked state. In addition, when the front panel 2 is further raised by hand from this temporarily locked state, the above-described final locked state is obtained.

  Specifically, at least when the connecting shaft 23A of the arm 23 reaches the right region from the line L connecting the rotating shaft 22A of the triangular plate 22 and the connecting shaft 23B of the arm 23, as shown in FIG. The lowermost part 2B '(see FIG. 15) of the groove 2B of the front panel 2 is locked to the claw 24 projecting from the front surface of the case body 1A, and cannot be further raised. Accordingly, the triangular plate 22 and the arm 23 that constitute a part of the interlocking mechanism 20 (connected to the connecting member 21 having the rotating shaft 21A engaged with the rotating bearing 2A (see FIG. 6) of the front panel 2). However, at least at a predetermined position beyond the neutral line L, it can no longer be rotated to the right, and a locked state (first locked state) is established.

(XI) Regarding the second lock mechanism 60B:
The second lock mechanism 60B prevents the front panel 2 from descending when water is supplied to the water supply tank 3 (or cleaning of the liquid dish 7B and the filter 4), and the tray 7 can be safely inserted and removed. For this purpose, it operates when the front panel 2 is pulled up to a predetermined lifted position, and the front panel 2 is temporarily locked at the lifted position.

When the front panel 2 is pulled up to the state shown in FIG. 15, the second lock mechanism 60 </ b> B of the present embodiment engages with the rotary bearing 2 </ b> A (see FIG. 6) provided at the lower portion of the inner side surface of the front panel 2 and rises. coupling member 21 the rotating shaft 21A projecting from the (see FIG. 17), as shown in FIG. 18, is engaged with the leaf spring 13 provided on the top of the lock chamber S ₇ of the water supply tank chamber S _1.

Specifically, in FIG. 18, the leaf spring 13 is pivotally supported in a state where the base portion is fixed to the upper right corner of the lock chamber S ₇ , and a convex portion 11 </ b> A protruding upward from the intermediate portion to the tip is formed. In addition, 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, the connecting member 21 is formed with a recess 21 </ b> B following the protrusion 13 </ b> A of the leaf spring 13 at the bottom.

  Accordingly, when the front panel 2 is raised to a predetermined position and the connecting member 21 is rotated clockwise by a predetermined angle in accordance with the raising operation, the concave portion 21B enters and fits the convex portion 13A. A locked state is performed. In order to release this locked state, the locked state may be released by lowering the front panel 2 with a force larger than the elastic force of the leaf spring 13 and pushing down the leaf spring 13.

(VIII) Damper mechanism 70:
As shown in FIG. 16, the damper mechanism 70 according to the present embodiment meshes with a damper member 71 (see FIG. 17) fixed on the substantially central side of the triangular plate 22 and a gear 71 </ b> A provided on the damper member 71. An arc-shaped external tooth 72A is provided, and a sector gear 72 is rotatably mounted on the rotating shaft 22A.

  The damper member 71 is filled with damper oil. Even if a large rotational force is applied to the gear 71A, the rotational force is reduced by utilizing the viscosity of the damper oil. 4A rapid descent operation can be prevented.

  The sector gear 72 is pivotally assembled to the pivot shaft 22A of the triangular plate 22 at the center side, but the two locations 72B and 72C on the outer peripheral edge side provided with the external teeth 72A are fixed to the case body 1A with screws or the like. Thus, the case main body 1A is in an immobile state.

  Therefore, according to the damper mechanism 70 of the present embodiment, when the front panel 2 is pulled down after the front panel 2 is pulled up, the front panel 2 is lowered by an excessive force or the filter unit 4A is forcedly pushed. Even so, the rapid lowering operation of the front panel 2 and the filter unit 4 </ b> A can be braked by the damper force of the damper member 71. Therefore, the front panel 2 and the filter unit 4A can be effectively prevented from being damaged by the rapid lowering operation of the front panel 2 and the filter unit 4A.

(IX) About the gear meshing mechanism 81:
Gear meshing mechanism 81, as shown in FIG. 21, a filter unit 4A, when or videos or drawers from the humidifying filter chamber S _3, the drive gear 81B which is provided on the filter for motor 81A of the case main body 1A and the filter unit This is for adjusting the meshing state with the driven gear 4E for rotating operation of the filter 4 installed in the filter holder 4D of 4A (see FIG. 1). In other words, as shown in FIG. 21, the gear meshing mechanism 81 is designed to absorb backlash by providing a slight play (gap) δ between the filter unit 4A and the filter holder 4D. . In the gear meshing mechanism 81 of the present embodiment, as shown in FIGS. 1 and 21, the lower side is inclined toward the front by an angle θ with respect to the case body 1A.

  Therefore, according to the gear meshing mechanism 81, when the filter unit 4A is moved up and down, the fitting operation between the filter unit 4A and the filter holder 4D provided for installing the driven gear 4E can be performed as follows. It becomes like this.
