Description

[Detailed Description of the Invention] The present invention relates to an improvement of a humidifier equipped with a tank for metered water supply.

This kind of conventional humidifier has a water storage tank provided at the bottom of the outer box, the tank is removably mounted inside the outer box, and a discharge port equipped with a valve case having a valve device is provided at the bottom of the tank. The structure is such that a fixed amount of water is always supplied into the water storage tank from the discharge port of the tank via the valve device and the valve case.

However, according to the conventional configuration described above, the water spout is generally used as a water inlet, so when injecting water into the tank, it is necessary to remove the valve case attached to the discharge port one by one. The valve device may be damaged during installation or removal of the valve case.

The present invention was made in view of the above circumstances, and its purpose is to provide a partition wall that partitions a part of the water tank at the bottom of the outer box into a small storage chamber, and to provide a tank that can be detachably attached to the outer box. A discharge port facing into the water storage tank is provided at the bottom of the tank, a valve device is provided at the discharge port, and a bulge having a water inlet facing into the storage chamber is provided at the bottom of the tank. By attaching a removable cap to the water inlet, it is possible to prevent water from being injected into the tank from the water inlet in the bulge and damaging the valve device at the outlet as much as possible. Normally, water does not accumulate in the storage chamber facing the tank, so even if the bulge suddenly enters the storage chamber when the tank is attached to the outer box, there will be no water splashing. To provide a humidifier in which even when water leaks due to incomplete blocking of a water inlet, the water leakage stops naturally when the water reaches a predetermined level in a storage chamber, and there is no risk of the water leaking outside. It is in.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

Reference numeral 1 denotes an outer box with openings on both the upper and lower sides, an air intake port 2 is formed on the left side wall, and a cover plate 3 is attached to the opening on the top surface.
A water storage container 4 is attached to the bottom opening by, for example, a knob 5 so as to close the opening.

Further, a spout 6 is formed in the left half of the cover plate 3, and an insertion/removal lower part is formed in the right half, and a wind guide tube 8 is provided downward at the peripheral edge of the spout 6. It is integrally molded.

Further, the dehydration container 4 has a top-bottom shape, and the inside is a water storage tank 9.
A partition wall 10 is integrally formed upwardly protruding from the bottom wall on the right end side of the water storage tank 9, and the partition wall 10 allows storage of a small volume on the right end side of the water storage tank 9. The chamber 11 is partitioned.

Reference numeral 12 denotes a ventilation type humidifying mechanism disposed in the left half of the outer box 1, which is driven by a drive motor 13 disposed within the air guide tube 8. Blowing blades 14 rotated by this drive motor 13. It consists of a water pump 15 rotated by the drive motor 13 together with the air blowing blade 14, and a cylindrical wet member 16 surrounding the water pump 15.

Reference numeral 17 denotes a tank that is removably attached to the outer box 1 via an insertion/removal lower, and is in the shape of a substantially sealed rectangular container.

18 is a discharge port formed at the bottom of the tank 17;
is a cylindrical valve case of the valve device 21 which is removably screwed onto the discharge port 18 and watertightly via a packing 20, and the discharge port 18 of the tank 17 is located in a partition wall 19a formed approximately in the center of the interior thereof. An outlet 22 is formed which communicates with the outlet.

23 is an outlet 2 in the partition wall 19a of the cylindrical valve case 19.
A bearing ring 24 is integral with a plurality of ribs 23a formed protruding within the bearing ring 23, and 24 is a valve rod supported vertically and slidably on the bearing ring 23, and a valve body for opening and closing the outlet 22 is provided at its upper end. 2
5 is attached.

Reference numeral 26 denotes a compression spring interposed between the bearing ring 23 and the lower end flange 24a of the valve stem 24, which always urges the valve stem 24 downward, so that the valve body 25 is always kept free of flow. The outlet 22 is blocked.

Reference numeral 27 denotes a bulge formed at the bottom of the tank 17 to protrude downward, and a water inlet 28 is formed on one side of the bulge at a position below the lower end of the cylindrical valve case 19.

A cap 29 is removably attached to the water inlet 28 and watertightly screwed onto the water inlet 28 via a gasket 30.

Then, when the tank 17 is stored and installed in the outer box 1 from the insertion/removal lower part, the discharge port 18 , that is, the cylindrical valve case 19 faces into the water storage tank 9 , and the lower end flange 24 a of the valve stem 24 faces into the water storage tank 9 . The valve body 25
is adapted to open the outflow port 22, and the bulging portion 2
7 faces into the storage chamber 11 and its bottom wall is placed on the bottom wall of the storage chamber 11.

Next, the operation of this embodiment having the above configuration will be described.

First, with the tank 17 removed from the outer box 1, the cap 29 is removed from the water inlet 28, and the cap 29 is removed from the water inlet 28.
Water is supplied into the tank 17 from the tank 17, the cap 29 is again screwed onto the water inlet 28, and the tank 17 is installed into the outer box 1 from the insertion/removal lower part.

At this time, the valve stem 24 contacts the protrusion 31 to open the outlet 22, and the water in the tank 17 flows into the water storage tank 9 from the outlet 22, and the water level in the water tank 9 rises to the cylindrical valve case 19. When the lower end of the cylindrical valve case 19 is reached, the lower end opening of the cylindrical valve case 19 is sealed with water.
As a result, water injection into the water tank 9 is stopped, and the water level in the water tank 9 becomes a constant water level A.

When the water level in the water tank 9 decreases by performing a well-known humidifying operation by operating the humidifying mechanism 12, the water seal for the lower end opening of the cylindrical valve case 19 is broken, so that the water in the tank 17 is In the same manner as described above, the water flows into the water tank 9 one after another, and the water level in the water tank 9 is always maintained at a constant water level A.

In this case, since the storage chamber 11 is separated from the water tank 9 by the partition wall 10, no water is stored in the storage chamber 11.

By the way, the cap 29 was not tightened enough and the water inlet 2
If water leaks from the water inlet 8, this water will be stored in the storage chamber 11, but if the water reaches the upper edge 28a of the water inlet 28, the water inlet 28 will be blocked by the water. After that, water leakage is naturally stopped and the water level in the storage chamber 11 is kept constant at a predetermined water level B.

As described above, according to this embodiment, since the bulging portion 27 having the water inlet 28 is provided at the bottom of the tank 17 in addition to the discharge port 18, water can be replenished into the tank 17 from the water inlet 28. Therefore, unlike the conventional case, there is no need to remove the cylindrical valve case 19 of the discharge port 18, so damage to the valve device 21 can be prevented as much as possible. Therefore, unlike when replenishing water from the discharge port 18 into the tank 17, the tank 17 does not need to be in an upright position, and the tank 17 can be placed horizontally. Ice replenishment work can be carried out easily.

By the way, in the case where the bulging part 27 having the water inlet 28 is provided at the bottom of the tank 17 as in this embodiment, for example, the water storage tank 9 has a storage chamber 11 formed by the partition wall 10.
Assuming that no A is formed, when the water in the tank 17 drops below a predetermined level and the tank 17 is removed from the outer box 1 to replenish water, the water storage tank 9 will still have a constant water level A.
If the tank 17 is suddenly inserted into the outer box 1 after replenishing water in this state, the bulging portion 27 will violently collide with the water surface at a constant water level A, causing water to splash. This causes a problem in that the splashed water crosses the side wall of the water storage container 4, hits the inner surface of the side wall of the outer box 1, flows out from the lower part, and wets the surrounding surface.

In contrast, in this embodiment, a storage chamber 11 is partitioned into a part of the water storage tank 9 by a partition wall 10.
Since the bulging portion 27 faces the inside of the storage chamber 11, the water in the water storage tank 9 does not enter the storage chamber 11 and is stored therein. The problem of water splashing does not occur when the product is suddenly installed.

Further, according to this embodiment, the water inlet 28 by the cap 29
If the water inlet 28 is not completely blocked, water will leak from the water inlet 28, but when the leaked water reaches a predetermined water level B in the storage chamber 11 that blocks the water inlet 28, water leakage will occur naturally. Therefore, there is no risk that the water will continue to leak and the water will flow out to the outside. When this happens, the bulge 27 and the cap 29 are wet with water, so the user can know that a water leak has occurred, and can therefore drain the water stored in the storage chamber 11.

If the user reinstalls the tank 17 into the outer box 1 without noticing the water leak, the volume of the storage chamber 11 will be extremely small, and the volume occupied by the bulging portion 27 with respect to this storage chamber 11 will be small. Because of the large size, the bulge 2 is
Even if the water level is at the predetermined water level B when the 7 is stored in the storage chamber 11, the bulging portion 27 does not reach the storage chamber 11 as shown in FIG.
When the water level C is lifted from the water level C, the water level C is extremely low. Therefore, even if the bulging portion 27 suddenly enters the storage chamber 11 at the water level C, water splashing will not occur.

Note that the present invention is not limited to the embodiments described above and shown in the drawings; for example, the humidifying mechanism is not limited to the ventilation type humidifying mechanism 16, but may also be of various types such as an ultrasonic type or a pulverizing type. Various changes and modifications can be made without departing from the scope of the invention.

As explained above, the present invention includes a partition wall that partitions a part of the water storage tank at the bottom of the outer box into a small storage chamber, and a partition wall that partitions a part of the water storage tank at the bottom of the outer box into a small storage chamber. A facing discharge port is provided, a valve device is provided on the discharge port, a bulge portion having a water inlet facing into the storage chamber is provided at the bottom of the tank, and a cap is removably attached to the water inlet of the bulge portion. Because of this structure, it is possible to prevent water from being injected into the tank from the water inlet of the bulge and damaging the valve device of the discharge port as much as possible.Moreover, there is no space in the storage chamber facing the bulge during normal times. Water does not accumulate, so even if the bulge suddenly enters the storage chamber when the tank is attached to the outer box, there will be no water splashing.In addition, the water inlet is not completely blocked by the cap, so water will not leak out. To provide a humidifier in which even when water leaks, the water naturally stops leaking when it reaches a predetermined level in a storage room, and there is no risk of water leaking outside.
