Description

  The present invention relates to a humidifier that drops water from above a humidifying filter by a water supply path, humidifies air passing through the humidifying filter, and collects water that has fallen from the humidifying filter and received by a water receiving tray through a recovery water path. It is related with the water storage tank used suitably by the above, and its humidifier.

  A conventional vaporizing humidifier is designed to increase humidity by impregnating water supplied from a water supply tank into a humidifying filter that absorbs water and evaporating the impregnated water into the air passing through the humidifying filter. It is configured. In order to impregnate the humidifying filter with water, a general method is to immerse the lower end of the humidifying filter in the water in the water supply tank or in the tray supplied from the water supply tank, and suck the moisture filter by the capillary phenomenon. There is also a method in which water in the water supply tank is pumped up and applied to a humidifying filter.

Patent Document 1 discloses a humidifier provided with a container placement unit that can place a beverage container such as a plastic bottle in a lower part of a humidifier body that houses a humidifier, a blower, and a water supply pump for supplying water to the humidifier. Is disclosed. In the water supply pump, a tip is inserted into the beverage container in a state of being placed on the container placement portion, and a flexible pumping pipe for pumping up the humidifying water in the beverage container is communicated, so that a beverage container such as a PET bottle can be used. Use as a water tank.
The humidifying water pumped up by the water supply pump is supplied from a discharge port provided immediately above the vaporizing filter, which is a humidifying means, and impregnated in the vaporizing filter, while being collected in the humidifying water tank, The lower end is immersed. The operation of the water supply pump is controlled according to the water level detected by the water level sensor provided in the humidified water tank.

Hereinafter, the present invention will be described with reference to the drawings illustrating embodiments thereof.
FIG. 1 is a longitudinal sectional view showing the configuration of an embodiment of a water storage tank and a humidifier according to the present invention.
This humidifier is provided with an exhaust port 16 at an upper end portion in a rectangular tube-shaped housing 1 whose cross-sectional area gradually increases toward the lower portion, and two vertically connected air blowers are provided below the exhaust port 16. Fans 14 are provided. The two blower fans 14 and 14 are respectively attached to drive shafts that protrude vertically from the blower motor 13.

Below the blower fans 14, 14 in the housing 1, a humidifying filter 12 formed in a cylindrical shape having an end opened toward the blower fans 14, 14 is provided, and the side wall of the housing 1 surrounding the humidifying filter 12 is provided. Is formed in the air inlet 15.
Below the humidifying filter 12, a water receiving tray 11 is provided for receiving water flowing down through the humidifying filter 12.

The lower part in the housing 1 serves as a storage chamber 7 for storing a rectangular parallelepiped-shaped water storage tank 2, and the water storage tank 2 is provided by a door opening provided on the side wall of the housing 1 (storage chamber 7). As shown in FIG. 2, it is detachably attached to the humidifier body.
At the upper part of the water storage tank 2, a cover plate 18 detachably attached is provided. The water supply pipe 3 and the recovery water pipe 4 penetrate the cover plate 18 so as to extend in and out. The mouth of the water supply pipe 3 extending inside the water storage tank 2 is located above the mouth of the recovery water pipe 4 extending inside the water storage tank 2 as shown in FIG. Is provided.

The water supply pipe 3 and the recovered water pipe 4 are respectively connected to the connecting portion 5 of the humidifier body in a state where the water storage tank 2 is mounted on the humidifier body.
The water supply pipe 3 is connected to a suction pipe 9 that is a water supply path via a connecting portion 5, and the suction pipe 9 is connected to a water supply pipe 10 that is a water supply path via a pump 8.
The water supply pipe 10 is laid to the upper side of the humidifying filter 12, and the water supply pipe 10 above the humidifying filter 12 is provided with a plurality of water injection ports (not shown).
A tubular recovery water path (not shown) is provided between the water receiving tray 11 and the connection part 5, and the recovery water path is connected to the recovery water pipe 4 via the connection part 5.

In the humidifier having such a configuration, the water sucked up from the water storage tank 2 by the water supply pipe 3 and the suction pipe 9 by the pump 8 is poured into the upper end portion of the humidification filter 12 through the water supply pipe 10. The removed water is impregnated in the humidification filter 12. On the other hand, the air sucked from the intake port 15 by the blower fans 14 and 14 is humidified when passing through the humidifying filter 12, and blown into the room from the exhaust port 16 through the blower fans 14 and 14.
The water that has not been impregnated in the humidifying filter 12 is received by the water receiving tray 11 by washing away dissolved components of water such as calcium and magnesium adhering to the humidifying filter 12. The water received in the water receiving tray 11 is recovered in the water storage tank 2 via a recovery path (not shown) and the recovery water pipe 4.

  The water having a high concentration of dissolved components such as calcium and magnesium collected in the water storage tank 2 is accumulated at the bottom of the water storage tank 2 because the mouth of the recovery water pipe 4 is lower than the mouth of the water supply pipe 3. It is hard to be sucked up from. Thereby, it can suppress that the dissolved component density | concentration of the feed water from the feed water pipe 3 becomes high, and when the water level of the water storage tank 2 falls to some extent (for example, half), by replacing water, Deterioration of the humidification filter 12 (salt precipitation) can be prevented.

FIG. 4 is a longitudinal sectional view showing another configuration example of the water storage tank.
In this water storage tank 2a, a bottom region 19 that faces the inner port of the water supply pipe 3a is formed shallower than a bottom region 20 that faces the inner port of the recovery water pipe 4a. Similar effects can be obtained. In addition, each position of the opening | mouth inside the water supply pipe | tube 3a and the opening | mouth inside the collection | recovery water pipe 4a may be the same height, and may be the same as that of the case of the water storage tank 2.

FIG. 5 is a longitudinal sectional view showing another configuration example of the water storage tank.
The water storage tank 2b is provided with a partition plate 21 that partitions a bottom region facing the mouth inside the water supply pipe 3b and a bottom region facing the mouth inside the recovery water pipe 4b. The same effect can be obtained. In addition, each position of the opening | mouth inside the water supply pipe | tube 3b and the opening | mouth inside the collection | recovery water pipe | tube 4b may be the same height, and may be the same as that of the case of the water storage tank 2. FIG.

It is a longitudinal cross-sectional view which shows the structure of embodiment of the water storage tank and humidifier which concern on this invention. It is explanatory drawing which shows the form by which the water storage tank which concerns on this invention is mounted | worn detachably to the humidifier main body. It is a longitudinal section showing an example of composition of a water storage tank concerning the present invention. It is a longitudinal cross-sectional view which shows the other structural example of the water storage tank which concerns on this invention. It is a longitudinal cross-sectional view which shows the other structural example of the water storage tank which concerns on this invention.
