Abstract

PROBLEM TO BE SOLVED: To improve the distribution of wind velocity and to reduce the size of a box main body by arranging a swirl chamber of which direction of air intake hole is axial and the direction of blowing out hole is radial to a casing accommodating impellers of a centrifugal blower and introducing the intake air to the blowing out hole located axially backward. SOLUTION: A box main body 1 has an air intake hole 3 on a front surface and an air blow out hole 4 on a back surface and is provided with a filter 5, a humidifier 6, a chemical supplying tank 9 and a duct guide 10. The volute chamber of a fan casing that guide the intake air and blowing out air accommodates the impellers of a centrifugal blower 2 and is arranged inside the box main body 1. When the blower 2 is driven, the air sucked from the intake hole 3 of the box body 1 flows in the centrifugal direction of a shaft through the intake hole of volute chamber facing axial direction shown by an arrow. The distribution of the wind velocity is improved by flowing the air taken in from the axial direction to the intake hole backward in the axial direction.

[0002]

2. Description of the Related Art FIG. 3 is a diagram showing a humidifier of a ceiling embedded type using a conventional centrifugal blower. The configuration and operation will be described below with reference to FIG. In the figure,
The inside of the box body 1 has a hollow structure, and air is sucked from a suction port 3 provided on the front side of the box body 1 by a centrifugal blower 2 having strong wind pressure characteristics. And the air from which the dust has been removed is humidified by the humidifying element 6 to form humid air. The humid air is passed from the outlet 4 of the box body 1 to the duct 17.
Supply to the room through the like.

[0003] As shown in FIG.
The rotation axis of the centrifugal blower 2 installed in the
Since the suction port of the centrifugal blower 4 is disposed so as to be orthogonal to the flow of the air sucked from the box body 1, the suction port of the box body 1 The air sucked from 3 flows along the side surface of the box body and is sucked into the suction port of the centrifugal blower 4. The sucked air flows in a direction perpendicular to the rotation axis of the centrifugal blower 2 (centrifugal direction of the rotation axis), that is, along the side surface of the box body 1.

[0004] Next, the humidifying element 6 provided downstream of this flow and having absorbed water by utilizing the capillary phenomenon humidifies to humid air. In addition, since the temperature of air falls by this humidification process, in order to prevent this, the humidification element 6 is heated by a built-in heater (not shown), and is blown out after raising the air temperature to a predetermined temperature.

[0005]

As described above, in the conventional humidifier, the inlet and outlet of the box body are provided in the centrifugal direction of the rotating shaft of the centrifugal blower, and the centrifugal air is sucked from the centrifugal direction and centrifuged. Since the air velocity is blown in the direction, the wind speed near the center of the box main body, which is the air flow path, and the side wall side greatly differ, so it is necessary to take sufficient distance between the centrifugal blower and the humidifying element to average the air velocity, There is a problem that the box body, which is a road, becomes longer.

In addition, there is a problem that the method is only used for humidification, so that it can be used, for example, in hospitals and the like in which sterilized air must be supplied.

The present invention has been made to solve the above problems, and has as its object to provide a humidifier having a good wind speed distribution and a short box body. It is another object of the present invention to obtain a multifunctional humidifier.

A centrifugal blower that has an impeller and blows air, 3 is a suction port of the box body 1, 4 is an outlet of the box body 1, 5 is a device that adsorbs dust and the like in the air blown out by the centrifugal blower 2 and removes air. Filedone filters to be cleaned
Reference numeral 6 denotes a humidifier for humidifying the air cleaned by the filter 5, 7 a water supply tank for supplying water to the humidifier 6, 8 an inspection port, and 9 a chemical for supplying a chemical solution such as phytoncide to the humidifier 6. The supply tank 10 is a duct guide connected to each of the inlet and the outlet, and 11 is a filter holder shown in FIG. 2 and supporting a filter. Here, the phytoncide refers to an organic substance contained in a leaf of a tree, for example, a substance such as a terpene, an organic acid, an alkaloid, or a composite substance thereof.

As shown in FIG. 3, the impeller of the centrifugal blower 2 is housed in a swirl chamber 2b of a fan casing 2a for guiding the intake and blown air of the centrifugal blower.
It is installed in. The spiral chamber 2b of the fan casing 2a has one air inlet 2c and two air outlets 2c.
d, 2e, and two air blowing chambers 2f, 2g respectively connected to the air outlets 2d, 2e of the spiral chamber 2b, and sucks air from the axial direction on the impeller insertion side. It is structured to blow out in the axial direction on the side opposite to the insertion side. That is, these air blowing chambers 2f and 2g are provided on both sides of the spiral chamber 2b so as to surround the outer side wall surface of the spiral chamber 2b for accommodating the impeller of the blower, and the openings thereof are suction ports.
