Abstract

PROBLEM TO BE SOLVED: To provide a humidifier to prevent thickening of scale component condensation, such as calcium, contained in a large quantity in service water and not to progress adhesion to the inner surface and the bottom surface of a heating tank. SOLUTION: Overflowing water drips in a filter chamber 9 through a nozzle 11 connected to an inundation port 10 formed in a position below a steady water level (a) in a heating tank 5 and sucked by a suction filter 8 in the filter chamber 9 and vaporized by air from a blower 6 and hitting the suction filter 8. Meanwhile, fresh water is supplied in the heating tank 5, in which the steady water level is lowered, through a feed water pipe 3 from a feed water tank 1. By thinning scale component condensation, adhesion to the inner surface and the bottom surface of the heating tank 5 is prevented from progression, and the number of cleaning times can be decreased.

TECHNICAL FIELD The present invention relates to a humidifier,
More specifically, the present invention relates to a structure in which the concentration of scale components such as calcium contained in tap water in a large amount is suppressed so that the adhesion to the inner surface or the bottom surface of the heating tank does not proceed.

[0002]

2. Description of the Related Art A conventional humidifier has a heat shield provided in a water passage between a water tank and a heating tank as disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-74426, and the heat shield passes through the heat shield. By removing it from the water channel, scale components such as calcium that adhere to the water channel can be easily cleaned, and the separated heat shield can be easily cleaned. It has an effect of not causing troubles such as hindering water flow to and from the tank.

However, the invention described in the above publication is such that scale components such as adhered calcium can be easily cleaned. For example, in a heating tank,
It has not been possible to prevent scale components such as calcium from easily adhering.

DISCLOSURE OF THE INVENTION The present invention solves the above problems and suppresses the concentration of scale component concentration such as calcium contained in tap water in a large amount to prevent the adhesion to the inner or bottom surface of the heating tank. The purpose is to provide such a humidifier.

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a water storage tank for storing water supplied from a water supply tank and a water supply pipe from the water storage tank in a casing having an open upper part. Heating tank that heats the water supplied by a heater to atomize it as water vapor, a mixing chamber that mixes the air from the air blower and the water vapor from the heating tank provided in a suitable place, the air blower and the mixing chamber. A filter chamber that is partitioned as a part of an air passage that connects with, and that accommodates a water absorbing filter, and a nozzle that drops overflow water into the filter chamber that is connected to an overflow port provided below the steady water surface of the heating tank, A configuration in which a lid provided with an opening facing the mixing chamber is detachably attached to the upper part of the casing, and a suction port protruding from the opening is attached to the upper part of the mixing chamber. Become There.

Further, the tip of the nozzle is provided near the air guide hole provided in the filter chamber so as to face the blower.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will now be described in detail as examples based on the drawings. FIG. 1 is a sectional view of a humidifier according to the present invention.

The humidifier according to the present invention, as shown in the figure,
A water storage tank 2 having a float for storing water supplied from a water supply tank 1 is provided inside a casing A having an open upper portion, and water supplied from the water storage tank 2 via a water supply pipe 3 is heated by a heater 4 There is provided a heating tank 5 that is heated by the above and atomized as steam.

An air blower 6 is provided below the water storage tank 2, and an air blower 6 from the air blower 6 is provided above the heating tank 5.
A mixing chamber 7 for mixing the wind and the steam from the heating tank 5 as shown by the arrow a in (A) is provided.

A filter chamber 9 for accommodating the water absorbing filter 8 is defined as a part of an air passage connecting the blower 6 and the mixing chamber 7 adjacent to the mixing chamber 7, and the filter chamber 9 is set up by the blower 6. As shown by the arrows b and c in FIG. 1 (A), the blown air is sent to the mixing chamber 7 from the filter chamber 9 having the air guide holes 9a and the outlet holes 9b. There is.

An overflow port 10 is provided below the steady water surface a in the heating tank 5, and a nozzle 11 for constantly dropping the overflow water into the filter chamber 9 is connected to the overflow port 10.

An upper portion of the opened casing A is covered with a lid B which is detachably attached, and is projected upward from an opening C formed in the lid B. A suction port 13 is attached to the upper portion of the mixing chamber 9.

With the above configuration, the operation will be described below. By the nozzle 11 connected to the heating tank 5,
Overflow water is constantly dropped in the filter chamber 9 to
Water is absorbed by the water absorbing filter 8 housed in.

Then, by the blower 6, as shown in FIG.
As indicated by the arrow b, the air introduced from the air guide hole 9a is applied to the water absorbing filter 8 that has absorbed the water to evaporate the water content, and as indicated by the arrow c, from the outlet hole 9b as a humidified air flow. It can be delivered to the mixing chamber 7.

On the other hand, in the heating tank 5, the steady water surface a is lowered by constantly dropping it by the nozzle 11, so that the float provided in the water tank 2 functions and the water tank 1 Therefore, fresh water is replenished through the water supply pipe 3.

By replenishing the heating tank 5 with fresh water, it is possible to dilute the concentration of scale components such as calcium contained in tap water so as not to be concentrated. It is possible to prevent the adherence of particles from advancing, and it is possible to greatly reduce the number of times of cleaning.

Since the tip of the nozzle 11 is provided so as to face the blower 6 and to face the air guide hole 9a provided in the filter chamber 9, While applying the water dropped on the wind indicated by the arrow b to the filter 8, the water can be efficiently absorbed and effectively evaporated.

[0018]

As described above, according to the present invention,
It is a humidifier that suppresses the concentration of scale components such as calcium contained in tap water in a large amount to prevent the adhesion to the inner surface and the bottom surface of the heating tank.
