2. Description of the Related Art In recent years, humidifiers have been often used in ordinary homes and offices to prevent air from drying in living rooms, reception rooms, conference rooms, and the like. Humidifiers are classified into an ultrasonic type that emits water by vibrating water with ultrasonic waves and a heating type that emits steam by heating water.

FIG. 53 is a conceptual diagram showing a configuration example of a heating type humidifier 1 according to a conventional system. Humidifier 1 shown in FIG.
Has a tank storage container 2, and a tank 3 having a water inlet 3A is mounted upside down. That is, since the water inlet 3A is mounted toward the bottom of the tank container 2, the atmospheric pressure is not applied to the water surface C inside the tank after the tank is mounted. A valve body (not shown) is attached to the water inlet 3A, and when the tank 3 is mounted on the tank storage container 2, the valve body is opened by the projection 4 or the like, so that the water 5 can flow out.

[0004] A heating section 6 is provided adjacent to the tank housing 2 to heat water 5 supplied from the tank 3. The heating section 6 has a pan 6A for evaporation and a heat source 6B. The heat source 6B is attached to a lower portion of the evaporating dish 6A, and predetermined heat energy is applied to the water 5 of the dish 6A. For this purpose, a pipe 7 is provided so as to connect the tank container 2 and the plate 6A in the horizontal direction. In this type of humidifier 1, the water level A of the heating unit 6 and the water level B of the tank storage container 2 become equal due to the atmospheric pressure, but the water level (water surface C) in the tank and the water level A of the heating unit 6 are different. State (Pascal's principle).

Accordingly, when the water 5 in the heating unit 6 is heated and the hot water is reduced by evaporation, the heating unit 6 is removed from the tank 3.
Water 5 is supplied. This watering principle is almost equivalent to a bird waterer. A steam guide member 8 is attached to an upper portion of the heating unit 6, and the steam 9 is guided and discharged to the outside. The steam 9 can prevent the drying of air in a living room, a reception room, a conference room, or the like. According to the heating type, the surroundings of the humidifier are not stained white as compared with the ultrasonic type.

[0006]

However, according to the conventional heating type humidifier, since the water inlet 3A of the tank 3 is mounted with the water inlet 3A directed toward the bottom of the tank container 2, the tank 3 is mounted. The water 5 cannot be replenished in the tank while the tank is attached. Therefore, after the tank 3 is extracted from the tank storage container 2, the water 5 must be replenished in the tank, and the operability at the time of water replenishment is poor. By the way, without any contrivance, the water inlet 3
Structure with A (hereinafter referred to as upper water injection type tank structure)
In this case, the atmospheric pressure is applied to the inside of the tank during the water supply, so that the water level of the heating unit 6 rises and overflows.

In view of the above, the present invention has solved such a conventional problem. When an upper water injection type tank structure is adopted, even if the tank lid is opened, liquid does not flow out from the lower part of the tank. In addition, an object of the present invention is to propose a tank and a humidifier in which liquid can be added from the upper portion of the tank while the tank is mounted.

[0008]

In order to solve the above-mentioned problems, a tank according to the present invention has a liquid storage portion having an opening at an upper portion, a lid for opening and closing the opening, and a lid for closing the lid. A lower valve body that closes the first closed portion and a lower valve body that closes the second closed portion by external pressure on the downstream side of the upper valve body. The first closed portion is disposed at the same height or lower than the second closed portion.

According to the tank according to the present invention, the first closed portion is closed by the upper valve body with the closing of the lid,
The second closed part is closed by the lower valve body by the external pressure on the downstream side of the upper valve body, but the first closed part is at the same height or the same height as the second closed part. Since it is arranged below, the upper valve body can be closed at a position surrounding the lower valve body, so that the valve remains in the tank as compared with the case where the first closed surface is higher than the second closed surface. Not only can the amount of liquid to be reduced be reduced, but also the height of the tank can be reduced. Thereby, the tank can be sufficiently applied to a humidifier.

A humidifier according to the present invention is a humidifier having a tank for storing water and a humidifier for supplying water from the tank and evaporating or spouting the water.
A liquid storage portion having an opening at an upper portion, a lid for opening and closing the opening, an upper valve body for closing the first closed portion with the lid closed, and a downstream side of the upper valve body. A valve mechanism provided with a lower valve body for closing the second closed portion by pressing from the outside and provided at a lower portion of the liquid storage portion, wherein the first closed portion is provided on the second closed portion. On the other hand, they are arranged at the same height or below.

According to the humidifier according to the present invention, since the above-mentioned tank is applied, the first closed portion is closed by the upper valve body with the closing of the lid, and the downstream of the upper valve body. On the side, the second closed part is closed by the lower valve body due to external pressure, but since the first closed part is disposed at the same height or below the second closed part, The valve can be closed at a position where the upper valve surrounds the lower valve.

Therefore, not only can the amount of water remaining in the tank be reduced, but also the height of the tank can be reduced. This makes it possible to provide a heating and ultrasonic humidifier that is extremely easy to use.

This circular annular body 332 is fixed so as to be hooked on an edge portion of the opening 203 attached to the lower part of the tank main body 301. The rigidity of the tank 300 can be increased by the reinforcing frame 304.

FIG. 24 is a component assembly perspective view showing a configuration example of the link mechanism 34 of the tank 300. The reinforcing frame 304 shown in FIG. 24 has a circular ring-shaped body 329 at the upper part. The reinforcing frame 304 is formed by processing the same material as the above-described reinforcing frame 204 into a predetermined shape. A projection 333 is formed inside the circular ring-shaped body 329, and an opening 334 having a predetermined diameter is formed at the center of the projection 333. A pressed portion 319 having a predetermined length shorter than the pressed portion 219 is inserted into the opening 334.

An annular body 335 is formed at an intermediate portion of 37D, and the four columnar portions 37A to 37D are fixed and reinforced so as not to bend.

An Ω-shaped link mechanism mounting portion 337 is provided on the upper portion of the annular body 335. Link mechanism mounting part 3
Engagement holes 312 and 313 are opened at predetermined positions of 37. A pair of linear pressing force transmitting members 35A and 35B are movably attached to the holes 312 and 313 by pins 318 and the like. This pin 318 forms a fulcrum. One end of the pin 318 is fixed by a locking member 338 such as a split pin or a snap ring. A pressed portion 319 and a weight bar 339 as a valve body operating portion are movably attached to the pressing force transmitting members 35A and 35B. These are engaged by screws and pins 341 and 342.

The pin 318 and the pins 341 and 342 are shown in FIG.
Are assembled according to the alternate long and short dash line shown in FIG.
4 fixed. The upper valve body 32 is attached to the other end of the weight rod 339. A cup-type valve is used for the upper valve body 32, and is attached to the other end of the weight bar 339 with a screw 345 or the like with the cup portion facing downward.
In this example, the upper valve 32 is lowered by the weight of the weight bar 339 based on the release of the pressing force of the cap 21, and the upper opening of the support 224 is closed.

The upper valve body 32 and the pressing force transmitting member 35
A and 35B are made of the same material as the link mechanism 24. The upper valve body 32 is moved up and down by the link mechanism 34 and is closed so as to surround the cylindrical portion 155 of the support 224 shown in FIG. The lower valve 23 opens the lower opening of the support 224 based on external force in the same manner as the tank 200. Note that the method of attaching the support 224 to the lower part of the tank is the same as that of the tank 200, and a description thereof will be omitted. Reinforcement frame 30 with link mechanism
4, the tank 300 can be reinforced.

FIG. 25 shows the valve mechanism 3 when the cap 21 is closed.
FIG. 4 is a cross-sectional view of a tank 300 showing a configuration example of No. 0. In this example, it is assumed that the lower valve body 23 is closed. Therefore, the dovetail groove 2 of the tank body 201 shown in FIG.
The protruding portions 25 up to the bending portions (first positions) of 6A to 26D
At the time when A to 25D are pushed in, the pressed portions 319 of the link mechanism 34 shown in FIG.
By operating B, the upper valve body 32 is opened. Since the lower valve body 23 is closed, the water 5 does not leak from the lower part of the tank.

FIG. 26 is a cross-sectional view showing a configuration example of the humidifier 100 when the tank is mounted and the cap is opened, and FIG. 27 is a cross-sectional view showing a configuration example of the humidifier 100 when the cap is closed. In this example, the tank 300 is mounted on the tank container 2 shown in FIG.
The third pressed piece 157 is in contact with the projection 4. Accordingly, the pressed piece 157 overcomes the urging force of the spring 158 and moves upward, so that the lower valve body 23 is opened and the water 5 in the tank flows out into the tank storage container 2. This is assumed.

When opening the cap 21 in this state,
When the protrusions 25A to 25D are returned from the dovetail groove end portion (second position) to the bent portions of the dovetail grooves 26A to 26D of the tank main body 201 shown in FIG. 12A, and the cap 21 is further pulled upward, FIG. Weight bar 3 of the link mechanism 34 shown in FIG.
39 is lowered by gravity, and the pressing force transmitting members 35A,
5B operates and the upper valve body 32 is closed. At this time, the pressed portion 319 is pushed up. Therefore, tank 3
Water can be injected from the upper part of the tank while the humidifier 100 is attached to the humidifier 100.

After the water injection, when the cap 21 shown in FIG. 27 is loaded into the tank main body 201, the inside of the tank is brought into a non-atmospheric pressure state. That is, at the time when the protrusions 25A to 25D are pushed into the bent portions of the dovetail grooves 26A to 26D of the tank main body 201 shown in FIG. 12A, the pressed portion 319 of the link mechanism 34 transmits the pressing force as shown in FIG. The upper valve body 32 is opened by operating the members 35A and 35B. At this point, since the lower valve body 23 has already been opened, the water 5 can be gradually supplied from the lower part of the tank to the tank storage container 2 according to the pressure inside the tank.

As described above, according to the structure of the tank 300 of the present embodiment, the weight of the pressed portion 319, the pressing force transmitting members 35A and 35B, and the weight bar 339 causes
When the cap 21 is closed, the upper valve body 32 is opened, and the upper valve body 32 is always urged in the closing direction by its own weight. Therefore, when the cap 21 is opened, the lower valve body 23 is closed. Independently of the open / closed state, the pressing force by the link mechanism 34 is released, and the upper valve body 32 is closed by the weight of the weight rod 339 itself.

At this time, since the atmospheric pressure is applied to the water surface, when the water 5 is present in the tank, the weight of the water 5 is also applied, so that the upper valve body 32 covers the upper opening of the support 224. So closed. Therefore, even when the lower opening of the support 224 is opened by the lower valve body 23, the water 5 does not flow out from the lower part of the tank. Take out the tank 300 without turning it over
With the cap attached, the cap 21 can be opened and water can be added to the tank 300 from above.

Thus, the tank can be sufficiently applied to the humidifier 100. Further, there is no need for a spring body that constantly biases the upper valve body 32 in the closing direction. This makes it possible to provide a very convenient heating humidifier 100 and an ultrasonic humidifier.

(4) Tank provided with another cup-shaped valve FIG. 28 is a cross-sectional view showing a configuration example of a tank 400 as an embodiment applicable to the humidifier 100. FIG. 29 is a cross-sectional view showing a configuration example of the tank 401 after the structure change. In this embodiment, when the tank structure of the upper water injection type is adopted, the double valve mechanism 40
When the cap 21 is opened, the lower valve body 23
Independently of the open / closed state, the upper valve body 42 is closed at a position surrounding the lower valve body 23 so that the water 5 does not flow out from the lower part of the tank even when the cap 21 is opened. At the same time, the water 5 can be added from the upper part of the tank while the tank 400 is mounted on the storage container 2 or the like. In addition, the water 5 can be effectively used up to the opening of the lower valve body 23, and the height of the tank 400 can be reduced.

In the tank 400 shown in FIG. 28, an upper valve body 42 composed of a cup-shaped valve is attached to the connecting member 214 of the valve mechanism 40 instead of the upper valve body 22 of the valve mechanism 20 shown in FIG. In addition, the valve mechanism 40 includes the tank 200.
Is used. The components having the same reference numerals as those of the tank 200 have the same functions, and the description thereof will be omitted.

In the valve mechanism 40, the upper valve body 42 is opened and closed by the link mechanism 24 at a position surrounding the lower valve body 23 at least based on the opening and closing operation of the cap 21. For example, the valve mechanism 40 releases the pressing force of the cap 21 due to the opening operation of the cap 21, and the urging force of the spring body 222 of the link mechanism 24 causes the upper valve body 4
2 is closed. Of course, the link mechanism 24 is
24 and fixed to the lower part of the tank.

In this example, two openings 41 and 43 are formed in the support 224, and the upper part has a large diameter and the lower part has a small diameter. Also in this example, the large-diameter-side opening 41 is opened by the upper valve body 42 based on the pressing force of the cap 21 exceeding the urging force of the spring body 222 of the link mechanism 24. The opening 43 on the small diameter side is opened and closed by the lower valve body 23 based on an external force. Here, a surface where the large-diameter side opening 41 and the upper valve body 42 are in contact with each other is a first closed surface (hereinafter referred to as an upper valve body opening / closing surface).
When the surface where the opening 43 on the small diameter side and the lower valve body 23 are in contact with each other is a second closed surface (hereinafter referred to as a lower valve body opening / closing surface), the upper valve body opening / closing surface and the lower valve body opening / closing surface Are made substantially the same. With this definition, the upper valve body 42 can be opened and closed so as to surround the lower valve body 23.

Further, in FIG. 28, if the length of the support 224 protruding from the lower part of the tank is denoted by β, the length β determines the height h0 of the tank 400. That is, when the length β of the support 224 occupies a large amount with respect to the tank height h0, the entire humidifier must be increased. Then, as shown by the two-dot chain line in FIG. 28, the fulcrum p of the pressing force transmitting member 214 is shifted upward,
19 and the length of the cup portion of the upper valve body 42 are reduced. Even with this configuration, the link mechanism 44
Operate similarly to the link mechanism 24. In addition, cap 2
The operation of opening and closing 1 is the same as that of the tank 200, and the description thereof is omitted.

When the upper and lower valve body opening / closing surfaces are made the same as described above, the support 2 of the tank 401 shown in FIG.
The length β ′ of 24 ′ can be made shorter than the length β of the support 224 shown in FIG. 28, and the lower part of the tank 401 can be made flat. In FIG. 29, the pressed portion 219 'has a shorter length, and the upper valve body 42' has a shorter cup portion. Valve mechanism 40 '
Is constituted by an upper valve body 42 ′ and a lower valve body 23. Therefore, the height of the tank 401 can be reduced as compared with the other tanks 200 to 400 without reducing the tank capacity as compared with the other tanks 400.

In this manner, the tank 40 of this embodiment is
According to the structure of No. 0, when the cap 21 is opened,
The pressing force of the link mechanism 24 is released, and the upper valve body 42 is moved to the lower valve body 2 independently of the open / close state of the lower valve body 23.
Since it is closed at a position surrounding 3, water 5 does not flow out from the lower part of the tank. In addition, the upper valve body opening / closing surface is closed by the upper valve body 42 with the lid closing of the cap 21, and the lower valve body opening / closing surface is closed by the lower valve body 23 on the downstream side of the upper valve body 23 due to external pressure. Is done. At this time, since the atmospheric pressure is applied to the water surface, the weight of the water 5 in the tank is also applied, and the upper valve body 42 is moved to the large-diameter opening 4 of the support 224.
1 is closed to close.

Therefore, the support 224 is formed by the lower valve 23.
Even when the small-diameter opening 43 is opened, the water 5 does not flow out from the lower part of the tank. Therefore, with the tank 400 attached to the storage container 2 or the like, the cap 21 is opened and the tank is opened from the upper part. 400 can be supplemented with water 5. Moreover, since the upper valve body opening / closing surface is arranged at the same height as the lower valve body opening / closing surface, the valve can be closed at a position where the upper valve body 42 surrounds the lower valve body 23.

Thus, as compared with the case where the upper valve body opening / closing surface is made higher than the lower valve body opening / closing surface, not only the amount of water 5 remaining inside the tank (ineffective portion) can be reduced, but also the tank 400 The height can be reduced. Therefore,
The tank can be sufficiently applied to the humidifier 100,
It is possible to provide a heating humidifier 100 and an ultrasonic humidifier that are extremely easy to use.

Is the maximum opening angle. The bottom of the cam is set such that the movable piece 505 has a gap (clearance) with respect to the cam portions 55A to 55D with respect to the position where the upper valve body 52 is completely closed.

FIG. 33 is a perspective view showing an example of the configuration of the cap 51 and the opening 502 of the tank 500. As shown in FIG. In the tank 500 shown in FIG. 33, the opening 502 of the tank main body 501 is not provided with the protrusion 227 described in the tank 200. This is because the pressed portion 219 is connected to the connecting member 519.
Instead, the linking member 519 has the structure of the link mechanism 54 attached to the movable piece 505.

The projections 25A to 25 of the cap 51
The arrangement of D and dovetail grooves 26A to 26D is as described for cap 21. Since the packing member 226 and the groove 225 thereof are also as described above, the description thereof will be omitted. Also in this example, the projections 25A to
The cap 51 is attached to the opening 502 along the 25D and L-shaped dovetail grooves 26A to 26D (see FIG. 10).

A hole 5 is provided inside the projection 53 shown in FIG.
06 is formed to reduce the weight of the cap 51. The air is confined in the hole 506. Therefore, suction and exhaust ports 56A to 56D are formed corresponding to the four locations of the cam portions 55A to 55D.
Air is circulated between the outside and the outside. of course,
The intake / exhaust port 56A may be provided at one location. 56A
Thereby, the pressure inside the tank and the pressure in the hole 506 can be made equal.

Subsequently, when the cap 51 is closed, the valve mechanism 5 is closed.
The operation of 0 will be described. FIGS. 34 and 35 show an operation example (parts 1 and 2) of the valve mechanism 50 when the cap 51 is closed.
FIG. 5 is a cross-sectional view of a tank 500 illustrating In this example, when the tank is not mounted, the opening 502 of the tank body 501 is opened.
It is assumed that when the valve mechanism 50 is closed by the cap 51, the valve mechanism 50 is operated by the rotation operation mechanism 59.
In this example, first, in the first stage, the cap 51 is placed vertically to the dovetail groove 26A of the tank body 501 shown in FIG.
Is closed so as to move the projection 25A. And
The packing member 22 is provided between the cap 51 and the inside of the tank.
6 makes the airtight state.

At this stage, that is, at the stage when the cap 51 shown in FIG. 34 is attached to the opening 502 of the tank body 501, the upper valve body 52 of the valve mechanism 50 is not opened. In this state, the movable piece 505 of the link mechanism 54 is not in contact with the cam portion 55A of the rotary operation mechanism 59, that is, a gap is formed between the movable piece 505 and the cam portion 55A.
Therefore, the pressing force from the rotation operation mechanism 59 to the link mechanism 54 is not generated.

Thereafter, as the second stage, when the cap 51 shown in FIG. 35 is rotated in a predetermined direction, the cam portion 55A comes into contact with the movable piece 505. The cam part 55A
When the user pushes the movable piece 505, the movable piece 505
Pushes down the connecting member 519. By the pressing force of this connecting member 519, the valve body operation part 514 causes the upper valve body 52
, The upper opening of the support 224 is opened.

Accordingly, the upper valve body 52 can be operated after the inside of the tank has been brought to a non-atmospheric pressure state and after the rotation operation of the cap 51. Note that the operation of the valve mechanism 50 when the tank is mounted only adds a state in which the lower valve body 23 is opened, and a description thereof will be omitted (see FIGS. 26 and 27). As described above, according to the structure of the tank 500 according to the present embodiment, in a state in which the atmospheric pressure is applied to the inside of the tank (a state in which the airtightness is not maintained), the rotation operation mechanism 59 does not shift to the link operation, and The upper valve body 52 of the valve mechanism 50 remains closed.

That is, when the cap 51 is attached to the opening 502, the projection 25A
25D reaches the bent portion (first position) of the dovetail grooves 26A to 26D, the opening 502 is closed, and the cap 51 and the tank body are closed by the packing member 226 while being pushed into the bent portion. Part 5
01 is kept airtight. Thereafter, the cap 51 is set at an angle of about 90 from the bent portion in the circumferential direction.
When rotated by °, the link operation is started at the stage where the rotation operation is performed to the end portion (second position) of the dovetail grooves 26A to 26D. Therefore, when the cap 51 is not completely closed, the link mechanism 54 is not operated and the upper valve body 52 is not opened, so that the water 5 can be prevented from flowing out from the tank bottom to the outside.

The clearance between the movable piece 505 of the link mechanism 54 and the cam portion 55A of the rotary operation mechanism 59 absorbs variations in tank accuracy and other rigidities of the tank 500, thereby stably operating the upper valve body 52. Therefore, a highly reliable tank can be provided. Moreover, the tank is humidifier 1
The heating humidifier 100 and the ultrasonic humidifier provided with the tank 500, which can be sufficiently applied to P.00 and have excellent usability, can be provided.

Shows the tank structure when the lid is opened. In this embodiment, when the tank structure of the upper water injection type is adopted, the tank 6
A valve mechanism 60 having a double structure having an upper valve body 62 and a lower valve body 23 is provided below 00, and a cap 61 having a rotation operation mechanism 69 for operating the valve mechanism 60 is provided.
After the inside of the tank is brought to a non-atmospheric pressure state, the upper valve body 62 of the valve mechanism 60 is opened to prevent the water 5 from flowing out from the tank bottom to the outside in a state where the cap 61 is not completely closed. It is like that.

A tank 600 shown in FIG. 36 has a tank main body 601. The appearance is formed in a cubic shape in the same manner as the tanks 200 to 500. The tank main body 601 has a larger opening 603 at the lower part of the tank than the tanks 200 to 500 described above, and the opening 60
The center of 3 is shifted from the center of the tank 600 by γ, for example, to the right. Of course, the opening 603 may be shifted to the left. A support 224 'is attached to a lower portion of the tank 600. The support 224 'is formed by shifting the mounting position of the lower valve body 23 to the right from the center of the support 224 described above.

Further, an opening 602 is formed in the upper center of the tank body 601 shown in FIG. This opening 6
A water supply cap 61 is engaged with 02 so as to be openable and closable.
After the cap 61 is closed, the inside of the tank is brought to a non-atmospheric pressure state. Also in this example, the water 5 is freely added from above with the cap 61 removed. This cap 61
Has a rotation operation mechanism 69, and operates to open the upper valve body 62 after the inside of the tank is brought to a non-atmospheric pressure state.
The rotation operation mechanism 69 has a cap 61 as a protruding member.
Is provided with a columnar protruding portion 63 inside. In the center of the back side of the protruding portion 63, for example, a square concave hole 61 is formed.
4 are formed. Hole 614 may be triangular, pentagonal, hexagonal.

A double valve mechanism 60 is attached to the opening 603 at the bottom of the tank body 601. The valve mechanism 60 includes a faucet mechanism 64, a rotary frustum-shaped upper valve body 62, a liquid partition 65, and a sucker-type lower valve body 23. The upper valve body 62 has a protrusion 605 at one end and a rod-shaped body (hereinafter referred to as a shaft) 606 that receives a rotational force when the cap 61 is opened and closed. In this example,
The convex portion 605 of the shaft 606 has substantially the same square shape as the concave portion 614 of the rotation operation mechanism 69 of the cap 61.

The liquid partition 65 is formed so as to partition the lower part of the tank body 601 with good watertightness, and the upper opening 60
7 and a lower opening 608. Liquid partition 65
The upper opening 607 is opened and closed by the upper valve body 62, and the upper valve body 62 is opened and closed by the faucet mechanism 64 independently of the lower valve body 23 based on at least the opening and closing operation of the cap 61. . In particular, when the cap 61 is opened, the upper valve body 62 is closed independently of the open / close state of the lower valve body 23, and the upper valve body 62 is opened by the rotational force of the cap 61 accompanying the closing operation. . The upper valve body 62 is attached to the faucet mechanism 64. Due to the bending of the shaft 606 of the faucet mechanism 64, the lower valve body 62 is rotated in response to the rotation operation when the cap 61 is closed. The lower valve 23 opens and closes the lower opening 608 of the liquid partition 65 based on external force.

FIG. 37 is a component assembly perspective view showing an example of the structure of the faucet mechanism 64. As shown in FIG. In this example, the faucet mechanism 64 is shown in FIG.
Has a circular base 611 shown in FIG. Base 61
The size of the outer diameter of 1 is substantially equal to the inner diameter of the support 224 '. The base 611 has a truncated cone-shaped hole 612 and an arc-shaped water supply port (upper opening 607) formed on the upper surface thereof. The hole 612 is formed in the upper opening 6 by a water channel 613.
07.

The bottom of the base 611 is open, and the base 611 is mounted inside the support 224 '. The liquid partition 65 described above is formed by a space defined by the back surface of the base 611 and the support 224 '. An L-shaped support 604 is attached to the base 611. A hole 615 is formed at the tip of the support 604.
The support portion 604 is formed on the base portion 6 using screws (not shown) or the like.
11 is engaged. A shaft 606 having a square convex portion 605 at one end and a truncated upper valve body 62 at the other end is passed through the support portion 604.

The upper valve body 62 has an insertion hole 616 communicating with the water channel 613 of the hole 612 described above. After the shaft 606 is inserted into the hole 615, the end of the upper valve body 62 is fixed from the back surface of the base 611 by a screw 617 through a washer 618 and a spring body 619. The spring body 619 has a biasing force for pressing the lower valve body 62 against the hole 612. This is to improve the watertightness of the valve. Thereby, the upper valve body 62
Constitutes a so-called rotary faucet. The rotary faucet is provided with a water passage 61 in a hole 612 of a base 611 shown in FIG.
When the third valve 3 and the insertion hole 616 of the upper valve body 62 are in communication with each other, the upper valve body 62 is opened.

For the faucet mechanism 69, for example, a resin molded into a mold is used. The valve structure of the support 224 'is the same as that of the support 224, except that the mounting position of the lower valve body 23 of the support 224 is shifted rightward from the center thereof. Further, the method of attaching the support 224 'to the lower part of the tank is also described in the tank 200.
Since it is similar to the case of ~ 500, description thereof will be omitted.

FIG. 38 shows a rotation operation mechanism 69 of the cap 61.
39 is a bottom view showing an example of the configuration of FIG. 39, and FIG. 39 is a perspective view showing an example of the configuration of the cap 61. A rotary operation mechanism 69 shown in FIG. 38 is provided with a columnar projection 63 on the back side of the cap 61. Of course, also in this example, the projections 25A to 25D are provided inside the cap 61, and the dovetail groove 26 is formed on the outer periphery of the opening 602 of the tank body 601 (not shown).
A to 26D are provided. Inside the protruding portion 63, a rectangular recessed hole 614 is formed.

In this example, the entrance of the hole 614 shown in FIG. 39 has an inclined surface, so that the projection 605 of the shaft 606 can easily enter the hole 615. This is because the protrusion 63 of the cap 61 and the shaft 6 of the faucet mechanism 69
This is for the purpose of facilitating the alignment of the projections 605 of 06 and improving the operability of the cap 61 when the lid is closed. The projections 25A to 25D of the cap 61 and the dovetail groove 26A
The arrangement of to 26D is as described for the cap 21. Since the packing member 226 and the groove 225 thereof are also as described above, the description thereof will be omitted. Also in this example, the cap 71 is attached to the opening 602 along the projections 25A to 25D and the L-shaped dovetails 26A to 26D (see FIG. 10).

Subsequently, when the cap 61 is closed, the valve mechanism 6 is closed.
The operation of 0 will be described. FIG. 40 is a sectional view of the tank 600 showing an operation example of the valve mechanism 60 when the cap 61 is closed. In this example, when the tank is not mounted, FIG.
It is assumed that the cap 61 on the opening 602 of the tank main body 601 is positioned and the cap 61 shown in FIG. 40 is closed, and the valve mechanism 60 is operated by the rotation operation mechanism 69. . Of course, FIG.
The upper valve body 62 shown in FIG. 6 is in the “closed” state. In this state, the water passage 613 of the hole 612 of the base 611 and the insertion hole 616 of the upper valve body 62 cross each other. The lower valve body 23 is also in a closed state.

Based on this premise, the cap 61 is first closed so as to move the projection 26A of the cap 61 in the vertical direction of the dovetail groove 26A of the tank body 601 in the first stage (FIG. 3).
3). Then, the space between the cap 61 and the inside of the tank is made airtight by the packing member 226. At this stage, that is, at the stage when the cap 61 is attached to the opening 602 of the tank main body 601, the upper valve body 62 of the valve mechanism 60 is not opened. This is a state where the convex part 605 of the shaft 606 of the faucet mechanism part 64 is aligned with the concave hole part 614 of the protruding part 63 of the rotary operation mechanism 69. After that, the convex portion 605 is inserted into the hole portion 614 from the alignment state of the convex portion 605 and the hole portion 614.

That is, when the square convex portion 605 of the shaft 606 matches the rectangular hole portion 614 of the projecting portion 63, the convex portion 605 is inserted into the hole portion 614. Therefore, after the protrusion 605 of the shaft 606 is inserted into the hole 614 of the protrusion 63, the cap 51
Is rotated by an angle of 90 °, a hole 612 of the base 611 is formed.
From the cross state of the water channel 613 and the insertion hole 616 of the upper valve body 62, the water channel 613 and the insertion hole 616 shown in FIG.
Are in communication with each other, so that the upper valve body 62 is opened. Therefore, the upper valve body 62 can be operated by rotating the cap 61 after the inside of the tank is brought to a non-atmospheric pressure state. Note that the operation of the valve mechanism 60 when the tank is mounted only adds the state in which the lower valve body 23 is opened, and a description thereof will be omitted (FIGS. 26 and 2).
7).

As described above, according to the structure of the tank 600 of the present embodiment, after the cap 61 is closed and the inside of the tank is brought to a non-atmospheric pressure state, the upper valve body 62 of the valve mechanism 60 is rotated by the rotation operating mechanism 69. Is opened. In other words, the projections 25A to 25D of the cap 61 are replaced with the dovetail grooves 26A to 26D.
The opening 602 is closed at the time of reaching the bent portion (first position) of D, and the airtightness between the cap 61 and the tank main body 601 is improved by the packing member 226 while being pushed into the bent portion. The state is maintained.

Thereafter, when the cap 61 is rotated from this bent portion in the circumferential direction by approximately 90 °, the dovetail groove 2
At the stage of rotating operation to the end portion (second position) of 6A to 26D, the rotational force is transmitted to the valve mechanism 60, and the valve mechanism 60
As a result, the upper valve body 62 is opened, and the lower valve body 23 and the tank body 601 are communicated. Therefore, in a state where atmospheric pressure is applied to the inside of the tank (a state in which airtightness is not maintained), the upper valve body 62 is not opened, so that the water 5 can be prevented from flowing out from the tank bottom to the outside.

In addition, the variation in accuracy of the tank 600 in the left-right direction is absorbed by the bending of the shaft 606 of the faucet mechanism 54, and the protrusion 605 of the shaft 606 in the vertical direction.
And the clearance between the concave hole 614 of the protrusion 63 of the rotary operation mechanism 69 is absorbed, so that the upper valve body 62 can be operated stably. Thereby, the tank 50
0, a highly reliable tank can be provided. In addition, the tank can be sufficiently applied to the humidifier 100, and the heating humidifier 100 and the ultrasonic humidifier provided with the extremely convenient tank 600 can be provided.

In this embodiment, when a tank structure of an upper water injection type is adopted, a valve mechanism 70 having a multi-cylindrical valve body 72 is provided below the tank 700, and a rotation operation for operating the valve mechanism 70 is performed. After the cap 71 having the mechanism 79 is provided and the inside of the tank is brought into a non-atmospheric pressure state, the valve body 72 of the valve mechanism 70 is released from the "closed" restrained state, and the cap 71 is not completely closed. Thus, the water 5 can be prevented from flowing out from the tank bottom to the outside.

A tank 700 shown in FIG. 41 has a tank body 701. The appearance is formed in a cubic shape in the same manner as the tanks 200 to 600. An opening 702 is formed at the upper center of the tank body 701 shown in FIG.
A water supply cap 71 is openably and closably engaged with the opening 702, and after the cap 71 is closed, the inside of the tank is brought into a non-atmospheric pressure state. Also in this example, the water 5 is freely added from above with the cap 71 removed. The arrangement of the projections 25A to 25D and the dovetail grooves 26A to 26D of the cap 71 is as described for the cap 21. Packing member 226 and its groove 22
5 is also as described above, and the description thereof is omitted. Also in this example, the cap 71 has the projection 25A.
25D are attached to the openings 701 along the L-shaped dovetails 26A to 26D (see FIG. 10).

An opening 703 is formed in the center of the lower portion of the tank main body 701, and a support 724 is formed in the opening 703.
The support 724 is provided with a single-structured valve mechanism 70. This valve mechanism 70 has a suction cup type double-tubular valve body 72, a faucet mechanism section 74 as a rotation transmitting section, and a liquid partition section 75. The “closed” state is restricted, or the “closed” restricted state of the valve body is released. The liquid partition 75 is attached to the support 724 and is provided so as to partition the lower part of the tank body 701 with good watertightness, and has an upper opening 707 and a lower opening 708.

The cap 71 is provided with a rotation operation mechanism 79 for releasing the "closed" state of the valve body of the valve mechanism 70 after the inside of the tank is brought to a non-atmospheric pressure state.
As the rotation operation mechanism 79, a columnar projection 73 is provided inside the cap 71. For example, a square concave hole 714 is formed at the center of the rear side of the protrusion 73. Hole 714 may be triangular, pentagonal, hexagonal. In this rotary operation mechanism 79, only the depth of the hole 614 of the above-mentioned rotary operation mechanism 69 is defined, and the rotary operation mechanism 69 can be used as it is.

FIG. 42 is a component assembly perspective view showing a configuration example of the valve mechanism 70 and the faucet mechanism 74. In this example, the faucet mechanism 74 has a circular base 711 as shown in FIG. The outer diameter of the base part 711 is
Is approximately equal to the inner diameter of A circular upper opening 707 is formed on the upper surface of the base 711 as a water supply port.
The bottom of the base 711 is open, and the support 72
The base part 711 is attached to the inside of 4. The liquid partition 75 described above is formed by a space defined by the back surface of the base 711 and the support 724.

The base 711 has an L-shaped support 70.
4 is attached, and a female screw 712 is formed at the center of the base 711. A hole 715 is formed at the tip of the support 704. The support portion 704 is engaged with the base portion 711 using a screw (not shown) or the like. A rod-shaped body (hereinafter referred to as a shaft) 706 is passed through the hole 715 of the support portion 704. The shaft 706 has a convex portion 7 at one end.
05, and a screw-shaped male screw 713 is formed on the outer peripheral portion below the same. The male screw 713 is engaged with the female screw 712 of the base 711. Female screw 712
The male screw 713 is formed in a screw shape so that the shaft 706 rises when the cap 71 is rotated clockwise, and the shaft 706 descends when the cap 71 is rotated counterclockwise.

The projection 705 is formed in the recess 71 of the cap 71.
4 has substantially the same square shape. This is cap 7
This is for making the protrusion 705 of the shaft 706 detachable from the one recess 714. The shaft 706 is inserted and fitted into the hole 715 of the support portion 704 described above and is prevented from swaying. After being inserted into the hole 715, the shaft 706 is engaged with a female screw 712 at the center of the base 711.

[0146] The lower end of the shaft 706 is opposed to the upper center of the valve body 72 and receives the rotational force when the cap 71 is opened and closed. For example, when the cap 71 is opened, the state where the shaft 706 is lowered and the valve body 72 is closed is restrained. When the cap 71 is closed, the shaft 706 is raised to release the closed state of the valve body 72. The method for attaching the support 724 to the lower part of the tank is the same as that for the tanks 200 to 500, and a description thereof will be omitted. After the valve body 72 is released from the “closed” restrained state, the valve body 72 is opened by the double-tubular valve mechanism 70.

FIG. 43 is a component assembly perspective view showing an example of the configuration of a double-cylindrical valve body 72 of the valve mechanism 70. As shown in FIG. In this example, the valve mechanism 70 is attached to the support 724. A lower opening 708 is formed concentrically at the center of the support 724 shown in FIG. The lower opening 708 has an annular projecting wall 71.
6 and a circular step 717, which is opened and closed by a double-tubular valve 72.

The valve body 72 has a cylindrical body 721, a valve 722, a pressed part 723, and first and second spring bodies 725 and 726. Spring springs (coil springs) are used for the spring bodies 725 and 726. The cylindrical body 721 has a tapered portion 727 at the tip, a groove 728 below the tapered portion 727, and a slide hole 73 on the side surface.
1 and has a collar-shaped retaining portion 729 at the end. The tapered portion 727 is held down by the terminal end of the shaft 706. In this example, a spring 725 is attached between the back surface of the step portion 717 of the lower opening 708 and the retaining portion 729 of the tubular body 721. The spring 725 has a biasing force for pressing the valve 722 against the lower opening 708. This is to improve the watertightness of the valve.

A spring 72 is provided inside the cylindrical body 721.
6, and a pressed portion 723 having a different diameter at one end is movably mounted so as to prevent the spring 726 from coming off. A projection 732 is formed at the cylindrical portion of the pressed portion 723, and is engaged with the slide hole 731 of the cylindrical body 721. The urging force of the spring 726 is set to be larger than the urging force of the spring 725.
This is because the valve 722 is opened with good reproducibility when the closed state of the valve body 72 is released and an external force is applied to the pressed portion 723. The valve 722 has a hole 709.

In this example, after the components are assembled in the order of the pressed portion 723, the spring 726, the cylindrical body 721, and the spring 725, these assembled components are assembled into the lower opening 708 from the back surface, and the assembled components are assembled. When it comes to the surface of the lower opening 708, the valve 7 is attached to the cylindrical body 721.
22 is attached. The valve 722 is inserted into the groove 728 of the cylindrical body 721 with the large diameter side facing upward.
9 is inserted and fixed. The valve 722 is formed by processing natural rubber or synthetic rubber into a conical shape. Also, the support 7
When the base 24 is attached to the base 24, the faucet mechanism 74 is located on the valve body 72. And cap 71
, The "closed" state of the valve body 72 is restrained by the vertical movement accompanying the rotation of the faucet mechanism 74, or the "closed" restrained state of the valve body is released. With this configuration, the valve 722 opens and closes the lower opening 708.

Next, an operation example of the valve mechanism 70 of the tank 700 will be described. FIG. 44 is a cross-sectional view of the tank 700 showing an operation example of the valve mechanism 70 when the cap 71 is closed. In this example, when the tank is not mounted, the cap 71 on the opening 702 of the tank main body 701 shown in FIG.
Are aligned and the cap 71 is closed at the position shown in FIG. 44, and the valve mechanism 70 is operated by the rotation operating mechanism 79. Of course, the valve body 72 shown in FIG. 41 is in the “closed” state. In this state, the upper portion of the valve body 72 is pressed by the shaft 706, and the valve 7
Reference numeral 22 denotes a state in which the opening 708 is closed.

Based on this premise, the cap 71 is first closed so as to move the projection 26A of the cap 71 in the vertical direction of the dovetail groove 26A of the tank body 701 in the first stage (FIG. 4).
1). Then, the space between the cap 71 and the inside of the tank is sealed by the packing member 226. At this stage, that is, at the stage when the cap 71 is attached to the opening 702 of the tank main body 701, the valve body 7 of the valve mechanism 70
2 is not opened. This is a state in which no rotational force is transmitted from the rotary operation mechanism 79 to the faucet mechanism 74.

Therefore, when the cap 71 is rotated by an angle of 90 °, the shaft 706 moves upward from the upper portion of the valve body 72. As shown in FIG. 44, the "closed" restrained state of the valve body 72 is released, that is, the valve body 72 is brought into a state where it can be "opened". At this point, the valve 702 can be kept in the “closed” state because of the urging force of the spring 725.
As described above, after the inside of the tank is set to the non-atmospheric pressure state, the valve body 72 can be operated by rotating the cap 71.

FIG. 45 is a sectional view showing a configuration example of the humidifier 100 when the tank is mounted and the cap is closed, and FIG. 46 is a cross-sectional view showing a configuration example of the humidifier 100 when the cap is opened. In this example, the tank 700 shown in FIG.
The third pressed piece 723 is in contact with the projection 4. Thus, when the pressed piece 723 moves up, the spring 7
26 is greater than the biasing force of the spring 725, the spring 725 contracts and
Moves upward. Therefore, the valve 722 is opened, and the water 5 in the tank flows out into the tank container 2.

When water is injected with the tank 700 attached to the humidifier 100, first, the cap 71 shown in FIG. 45 is removed from the tank main body 701. At this time, by rotating the cap 71 in the direction opposite to the direction when closing the lid,
The shaft 706 shown in FIG.
Is pressed against the opening 708, and the valve body 72 is restrained in the “closed” state. Therefore, water can be injected from above the tank while the tank 700 is mounted on the humidifier 100.

As described above, the tank 70 according to this embodiment is
According to the structure of No. 0, after the cap 71 is closed and the inside of the tank is brought to a non-atmospheric pressure state, the “closed” restrained state of the double-tubular valve body 72 of the valve mechanism 70 is released by the rotation operating mechanism 79. Therefore, in a state where atmospheric pressure is applied to the inside of the tank (a state where airtightness is not maintained), the valve mechanism 70
As a result, the closed state of the valve body 72 is kept restricted.

Therefore, it is possible to prevent the water 5 from flowing out of the tank bottom to the outside when the cap 71 is not completely closed. In addition, the dual structure valve mechanism 20, 30,
The number of valve bodies 72 can be reduced by one as compared with 40, 50, 60. Thereby, a highly reliable tank can be provided.
In addition, the tank can be sufficiently applied to the humidifier 100, and the heating humidifier 100 and the ultrasonic humidifier provided with the extremely easy-to-use tank 700 can be provided. In this embodiment, a link mechanism 84 of a tank 800 described below can be applied instead of the faucet mechanism 74.

(8) Tank with Differential Valve Mechanism FIG. 47 is a sectional view showing a configuration example of a tank 800 as an embodiment applicable to the humidifier 100. In this embodiment, when the tank structure of the upper water injection type is adopted, the tank 8
00, a differential valve mechanism 80 is provided to open and close a valve element 82 at the lower part of the tank based on an opening and closing operation of a cap 81 and an external force. The closed state 82 can be maintained, and the water 5 can be prevented from flowing out of the tank bottom to the outside when the cap 81 is not completely closed.

A tank 800 shown in FIG. 47 has a tank main body 801. The appearance is formed in a cubic shape in the same manner as the tanks 200 to 700. An opening 802 is formed at the upper center of the tank body 801. This opening 8
02 is provided with a water supply cap 81 so as to be freely opened and closed.
After the cap 81 is closed, the inside of the tank is brought to a non-atmospheric pressure state. Also in this example, with the cap 81 removed, the water 5 is freely added from above.

The cap 81 having the structure shown in FIG. 10 is used. Regarding the arrangement of the projections 25A to 25D and the dovetail grooves 26A to 26D of the cap 81,
As described in 1. Since the packing member 226 and the groove 225 thereof are also as described above, the description thereof will be omitted. Also in this example, the cap 81 has protrusions 25A to 25D whose L-shaped dovetails 26A to 26D.
(See FIG. 10).

In this example, the shape of the lower part of the tank is different.
An opening 803 having a smaller diameter than that of the opening 700 is formed. An escape recess 83 is formed adjacent to the opening 803. By straddling the opening 803 and the recess 83,
A pair of bearing portions 85A and 85B are formed, and a valve mechanism 80 having a single structure is movably attached to the bearing portions 85A and 85B. The above-mentioned opening 803 is opened and closed by the valve mechanism 80.

This valve mechanism 80 has a differential valve element 82. The valve mechanism 80 has only one valve element 82, and based on the opening / closing operation of the cap 81 and an external force, the valve element 82
Is opened and closed. In this example, the "closed" state of the valve element 82 is restricted based on the opening operation of the cap 81, or the "closed" restricted state of the valve element 82 is released by the closing operation. After the release of the "closed" restrained state, the valve element 82 is opened and closed based on the external force. Also in this example, the cap 81 releases the "closed" state of the valve body 82 of the valve mechanism 80 after the inside of the tank is brought to a non-atmospheric pressure state.

In this example, a columnar reinforcing frame 804 is provided between the upper and lower portions inside the tank, and the rigidity of the tank is increased. The structure of the reinforcing frame 204 shown in FIG. 16 is applied to the reinforcing frame 804. Reinforcement frame 80
4, a circular ring-shaped body 229 is formed, and four columnar parts 27 </ b> A to 2 </ b> A are formed in a downward direction from the inside of the circular ring-shaped body 229.
7D is provided.

At the lower part of each of the columnar portions 27A to 27D, female screws 28A to 28D for engagement are formed. The circular annular body 229 is fixed so as to be hooked on an edge portion of the opening 802 of the tank main body 801. Also,
The terminal portions of the four columnar portions 27A to 27D are provided on the bottom of the tank main body 801 by female screws 28 (not shown) or the like.
A to 28D. Thereby, the rigidity of the tank 800 can be increased.

In this example, the valve mechanism 80 has a link mechanism 84, which is moved up and down by the pressing force of the cap 81. The link mechanism 84 is provided, for example, between the columnar portions 27A and 27C. The link mechanism 84 has an h-shaped support portion 811, and its leg portion has a columnar portion 27 </ b> A.
And the columnar portion 27C.

A pressing force transmitting member 805 having a certain pressing area is movably attached to the column 811 to form a fulcrum. The pressing force transmitting member 805
, A coil-shaped spring body 819 is attached as an urging means, and the pressing force transmitting member 805 is urged in a certain direction (downward in this example). Further, a cover transmitting portion 806 having a predetermined length is attached to the pressing force transmitting member 805 so that the pressing force of the cap 81 is transmitted to the pressing force transmitting member 805. Note that the method of assembling the components of the link mechanism 84 is substantially the same as that of the link mechanism 24, and thus the description thereof is omitted (see FIG. 17).

A projection 233 is formed inside the above-mentioned circular annular body 229, and an opening 234 having a predetermined diameter is formed at the center of the projection 233. The above-described cover transmission unit 806 is inserted into the opening 234. When the cap 81 is opened, the tip of the lid transmission unit 806 is made to go outside. When the cap 81 is closed, the tip is pushed and retracted into the opening 234. An annular body 235 is formed in an intermediate portion between the four columnar portions 27A to 27D, and is fixedly reinforced so that the four columnar portions 27A to 27D are not bent. Cover transmission unit 806
This is for accurately transmitting the pressing force by the pressing force to the pressing force transmitting member 805. The above-mentioned valve element 82 is arranged such that its upper part faces the pressing force transmitting member 805 of the link mechanism 84.

FIG. 48 is a component assembly perspective view showing a configuration example of the differential valve element 82 of the valve mechanism 80. As shown in FIG. FIG. 49 is a component assembly perspective view showing an example of mounting the differential valve element 82. In this example, the valve body 82 has a T-shaped shaft 812 shown in FIG. The shaft body 812 has a length of about 6 to 7 cm, and has a protruding portion 813 having a diameter of about 5 mm to 10 mm, a short shaft portion 814, and a long shaft portion 815. The shaft 812 is made of stainless steel or hard resin. A disc-shaped pressed portion 816 is provided at the tip of the protruding portion 813 so that the shaft body 812 is rotated by a predetermined angle based on an external force.

The long axis portion 815 of the shaft body 812 has an annular spring spring 817 and a cylindrical body 818 with an L-shaped projection.
Are movably inserted and attached. This cylindrical body 8
Reference numeral 18 has an L-shaped projection 821. Protrusion 82
1 is bent in a crank shape, for example, and has a tapered portion 823 at the tip thereof, and a groove 8 below the tapered portion 823.
24. The tapered portion 823 is pressed by the pressing force transmitting member 805 when the cap 81 is closed.
The valve 822 is attached to the groove 824 after parts are assembled. The hole 807 of the valve 822 is inserted and fixed in the groove 824 with the large diameter side facing upward. Valve 8
Reference numeral 22 is formed by processing natural rubber, synthetic rubber, or the like into a conical shape.

The spring 817 is a cylindrical member 818.
The cylindrical body 818 always moves following the shaft body 812, but the shaft body 812 is fixed and the cylindrical body 818 alone is rotated, or conversely, the cylindrical body 818 is wound around the cylindrical body 818. 818
Is fixed, and only the shaft body 812 can be rotated. In this example, the spring 81
One end of 7 is engaged with the projection 813 of the shaft 812, and the other end of the spring 817 is engaged with the projection 821 of the cylindrical body 818.

In this example, after the cylindrical body 818 and the spring 817 are engaged with the shaft 812, the long shaft 81
The rotation locking portion 808 is inserted and fixed to 5. The rotation locking portion 808 is a pin-shaped rotation stopper 825 shown in FIG.
have. This rotation stopper 825 is a cylindrical member 818.
The cylindrical body 818 is attached so as to press the projection 821 from above.
Of the shaft body 812 is restricted.

In this example, when the pressed portion 816 is pushed up while the cylindrical body 818 is restrained, the spring spring 8
The shaft body 812 rotates against the urging force of
Only the shaft body 812 rotates so that the projection 821 is separated from 08. On the other hand, when the tapered portion 823 is pressed down while the pressed portion 816 is restrained, the spring spring 8
The cylindrical body 818 is rotated against the urging force of the cylindrical member 17 so that the protrusion 821 is separated from the rotation locking portion 808.
Only 8 rotates.

Of course, in a state where the cylindrical body 818 and the shaft body 812 are not restrained at all, when the pressed portion 816 is pushed up, the rotation stopper 825 is brought into close contact with the projection 821 by the urging force of the spring spring 817. Shape 8
When both the shaft 18 and the shaft 812 rotate in the same direction and the tapered portion 823 is pressed down, the cylindrical body 818 and the shaft 812 both rotate in the opposite direction in the same state by the urging force of the spring 817. As a result, FIG.
9 is assembled.

The above-mentioned differential mechanism parts are a pair of bearing parts 85A, 85A formed in a projecting shape at the lower part of the tank shown in FIG.
B is movably attached to B. Long shaft portion 8 of shaft body 812
15 is inserted into the bearing 85A, and its short shaft 814 is inserted into the bearing 85B. At this time, the tapered portion 823 of the projection 821 of the differential mechanism component is inserted into the opening 803. The valve 822 is inserted into the groove 824 of the projection 821 and fixed from the inside of the tank 800 after the mechanical parts are attached to the lower part of the tank. The opening 803 at the lower part of the tank is opened and closed by the valve 822. An escape recess 83 is provided on the bottom surface of the tank 800 as a regulating portion, and the driving range of the shaft 812 is regulated. As a result, FIG.
Is completed, and the valve 822 opens and closes the opening 803.

Next, an operation example of the valve mechanism 80 of the tank 800 will be described. FIG. 50 is a cross-sectional view of the tank 800 showing an operation example of the valve mechanism 80 when the cap 81 is closed. In this example, when the tank is not mounted, the cap 81 on the opening 802 of the tank body 801 shown in FIG.
Is assumed, and the cap 81 shown in FIG. 50 is closed. Of course, the valve element 8 shown in FIG.
2 is a "closed" state. In this state, the upper part of the valve body 82 is pressed by the link mechanism 84, and the valve 822 closes the opening 803.

Assuming this, first, the tank body 8
The cap is closed so as to move the projection 26A of the cap 81 in the vertical direction of the dovetail groove 26A (see FIG. 47).
Then, the space between the cap 81 and the inside of the tank is made airtight by the packing member 226. After this airtight state, the lid transmission unit 806 of the link mechanism 84 is pressed down, so that the valve body 82 can be opened by the upward movement of the pressing force transmission member 805.
In this state, if no external force is still applied to the pressed portion 816 of the shaft 812, the water pressure inside the tank and the shaft 812,
The valve element 82 is biased in the valve closing direction by the rotational moment of the rotation locking portion 808 and the pressed portion 816 and the like.
Remains closed.

FIG. 51 is a sectional view showing a configuration example of the humidifier 100 when the tank is mounted and the cap is closed. FIG. 52 is a sectional view showing a configuration example of the humidifier 100 when the cap is opened. In this example, the valve element 82 shown in FIG.
By attaching the tank 800 in the enabled state to the tank container 2, the pressed portion 816 of the valve mechanism 80 comes into contact with the projection 4. When an external force is applied to the pressed portion 816, the valve element 82 is opened based on the external force. That is, since an external force is applied to the pressed portion 816 in an upward direction from the “openable” state of the valve element 82, the T-shaped protrusion 821 is in close contact with the rotation stopper 825 by the urging force of the spring 817. Both the shaft body 812 and the cylindrical body 818 rotate in the valve opening direction, and these rotate with the tapered portion 82.
The valve 822 can be opened because it moves in the direction to push up the valve 3. Therefore, the water 5 in the tank flows into the tank storage container 2.

When water is injected while the tank 800 is attached to the humidifier 100, first, the cap 81 shown in FIG. 51 is removed from the tank body 801. At this time, by rotating the cap 81 in the direction opposite to the direction when the lid is closed, the lid transmission unit 806 shown in FIG. 51 is raised. As a result, the pressing force transmitting member 805 is pushed down by the spring body 819, so that the valve 822 is pressed against the opening 803, and the valve body 82 is restrained in the “closed” state. That is, since the cylindrical body 818 to which the valve 822 is attached is restrained, even if the pressed portion 816 is pushed up, the spring spring 8
17 from the rotation locking portion 808 against the urging force
Only the shaft 812 rotates so that 1 is separated.

Therefore, water can be injected from the upper part of the tank with the tank 800 attached to the humidifier 100. In addition, when the tank 800 is removed from the tank storage portion 2 with the cap 81 opened, the external force applied to the pressed portion 816 is removed, and the T-shaped shaft 8 is removed.
Since only the valve 12 returns to the position regulated by the spring 817 and the rotation locking portion 808, the valve closing state of the valve body 82 is not restricted and the valve closing state of the valve body 82 is still restricted. (See FIG. 47).

As described above, the tank 8 according to the present embodiment is
According to the structure of No. 00, when the cap 81 is open, the state in which the valve element 82 at the lower part of the tank is closed by the differential valve mechanism 80 regardless of external force. When the cap 81 is closed and the inside of the tank is brought to a non-atmospheric pressure state, the valve element 82 is brought into a state where it can be "opened". Therefore, since the valve 822 can be opened based on external force from the time when the valve element 82 can be opened, the water 5 flows out of the tank bottom to the outside in a state where the cap 81 is not completely closed. Can be prevented. In addition, the number of the valve elements 82 can be reduced to one as compared with the valve mechanism 20, 30, 40, 50, 60 having a double structure.

In this embodiment, the case where the urging force of the valve body 82 in the valve closing direction uses the water pressure inside the tank and the rotational moment of the differential mechanism components is described, but the present invention is not limited to this. An urging means for forcibly urging the valve body 82 in the valve closing direction, that is, the pressed portion 816 in the downward direction, may be separately provided on the shaft body 812 or the like. In this embodiment, the faucet mechanism 74 of the tank 700 can be applied instead of the link mechanism 84. Thereby, a highly reliable tank can be provided. Moreover, the tank is connected to the humidifier 10.
The heating type humidifier 100 and the ultrasonic type humidifier having the tank 800 which can be sufficiently applied to 0 and which is extremely easy to use can be provided.

[0182]

As described above, according to the tank according to the present invention, the upper valve body for closing the first closed portion with the closing of the lid, and the external valve downstream of the upper valve body. A valve mechanism provided at a lower portion of the liquid storage portion with a lower valve body for closing the second closed portion by pressing from the first closed portion with respect to the second closed portion. At the same height or below.

With this configuration, even when the lid is opened with the lower valve body open, the liquid does not flow out from the lower part of the tank.
Liquid can be added from the top of the tank. Moreover,
The first valve can be closed at a position where the upper valve body surrounds the lower valve body.
As compared with the case where the closed surface is higher than the second closed surface, not only the amount of liquid remaining in the tank can be reduced, but also the height of the tank can be reduced.

According to the humidifier of the present invention, since the above-described tank is applied, when the lid is opened, the upper valve surrounds the lower valve independently of the open / close state of the lower valve. It is closed at the position where you do.

With this configuration, even if the lid is opened with the lower valve body open, water does not flow out from the lower part of the tank. Can be added. Moreover, not only can the amount of water remaining in the tank be reduced, but also the height of the tank can be reduced.

The present invention is very suitable when applied to an ultrasonic or heating humidifier capable of injecting water from the upper part of the tank.
