Abstract

PURPOSE:To ensure an adequate rate of air discharge so as to obtain a high deodorizing efficiency and miniaturize the overall size of device by attaching a deodorant material for removing the odorant components in the air to the inner surface of air passages of a centrifugal air impeller which comprises superposed annular corrugated plates. CONSTITUTION:When a centrifugal air impeller 6 is rotated by means of a motor 4, the air in its center is sucked, the air outside the body casing 1, i.e., the air in the room, is sucked into the center of the centrifugal air impeller 6. Such air is caused to flow into and through a number of air passages 11 in the rotating centrifugal air impeller 6 toward the radially outer side. During the process, deodorant components contained in the air are caused to be absorbed and deodorized by a deodorizing material attached to the inner surface of the air passages 11. Thereafter, the deodorized air from the air passages 11 is supplied through the air outlet 3 to the outside, i.e., into the room. The suction and delivery of the room air is thus continuously performed, and so, all the air in the room can be ultimately deodorized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a deodorizing device that removes odor components contained in indoor air.

(Prior Art) As this type of deodorizing device, the following are considered. That is, in an outer box provided with an intake port and an exhaust port, a ventilation path communicating with the intake port and exhaust port is provided, and a blower device consisting of a motor and a blower impeller is provided in the ventilation path, for example, on the exhaust port side. In addition, a plurality of filters each retaining a deodorizing agent for I days are provided between the air blower and the air intake port. Then, by driving the blower, indoor air is sucked in from the intake port, flows through the ventilation path toward the exhaust port, and sequentially passes through a plurality of layers of filters. During this time, odor components in the air are adsorbed by the deodorizer in the filter.
Deodorized air is discharged into the room from the exhaust port.

(Problem to be Solved by the Invention) However, with the above-mentioned conventional configuration, a space for arranging the air blower and a space for forming a ventilation path for providing a filter are required in the outer box, so the entire device is large. There was a flaw in the form.

In addition, in such a deodorizing device, when air passes through the filter, odor components in the air are adsorbed and deodorized by coming into contact with the deodorizing agent.
In order to obtain good deodorizing performance, it is necessary to increase the thickness of the filter or increase the number of filters so that the contact between the odor component and the deodorizing agent is good. On the other hand, in order to efficiently deodorize indoor air by increasing the exhaust amount per unit time, it is necessary to increase the area of the filter (the cross-sectional area of the ventilation path). Therefore, it has good deodorizing performance and large tl.
In order to ensure sufficient airflow, the filter must be large,
As a result, the size of the device becomes even larger.

The present invention has been made in view of the above circumstances, and its purpose is to provide a high deodorizing efficiency by ensuring sufficient υF air with good deodorizing performance, and to reduce the size of the entire device. To provide deodorizing equipment.

[Configuration of the Invention (Means for Solving the Problems)] The deodorizing device of the present invention sucks indoor air using a blower impeller disposed inside a main body case and rotated by a motor, deodorizes the indoor air, and removes the odor from the main body. The blower is configured to discharge air outside the case, and the blower is a centrifugal blower having a number of air passages formed by laminating annular corrugated plates connecting the inner and outer circumferences, and the centrifugal blower is It is characterized in that the inner surface of the air flow path of the impeller is loaded with a deodorizing agent for removing odor components from the air.

(Function) According to the above means, when the centrifugal blower wheel rotates, indoor air flows from the center side to the outer circumferential side in the air flow path, and odor components come into contact with the deodorizer in this air flow path and are removed. be done. Therefore, this centrifugal blower impeller exhibits a blowing action and also has a deodorizing function itself. In this case, by increasing the number of waves in the corrugated plate, the number of air channels can be extremely increased, and the cross-sectional area of each individual air channel can be made sufficiently small. The area is sufficiently large and the deodorizer can be supported over a wide area. As a result, the frequency with which odor components contained in the air flowing through each air flow path comes into contact with the deodorizing agent becomes extremely high, making it possible to perform high-performance deodorization. Moreover,
Since the cross-sectional area of the air flow path as a whole can be made sufficiently large, a large amount of air can be secured even if the air flow velocity in each air flow path is slow.

(Example) An example of the present invention will be described below with reference to the drawings.

First, in FIG. 1 showing the overall structure, reference numeral 1 denotes a square-shaped main body case, and an intake port 2 is formed at the center of the front surface of the main body case, and an exhaust port 3 is formed at the top surface. Inside the main body case 1, a motor 4 is attached to the central portion of the back via a mounting bracket 5, and a centrifugal blower wheel 6 is attached to the rotation shaft 4a of the motor 4. The centrifugal blower wheel 6 will be described below with reference also to FIGS. 2 to 4.

That is, 7 is an end plate having a circular outer circumferential shape, and a bulge 7a with an inner diameter that can surround the motor 4 is formed in the center of the end plate.
Furthermore, a boss portion 7b for attachment to the rotating shaft 4a of the motor 4 is formed at the center thereof. And this end plate 7
On the protruding side of the bulging portion 7a, a large number of annular tli 8 and annular waves 1 (two plates 9) are alternately laminated.

Both the annular plate 8 and the corrugated plate 9 are made of, for example, a plastic material and have an inner and outer diameter dimension equal to that of the end plate 7 and the groove. Further, the corrugated plate 9 has a shape in which a large number of wave-like undulations are formed over the entire circumference such that the crest line 9a of the wave extends in the radial direction between the inner and outer circumferences.

And these annular plates 8 and waveforms! The i29 carries a deodorizing agent as described later.

On the other hand, in the portions of the end plate 7 along the inner and outer peripheries of the annular [8 and corrugated plate 9], for example, four positioning pins (eight in total) are provided.
0 is protruding, ring-shaped! ! Notches 8a and 9b are formed in i28 and the corrugated plate 9 to correspond to the positioning pin 10. The corrugated plates 9 and the annular plates 8 are stacked alternately by fitting the respective notches 9b and 8a into the 6 positioning pins 10, and by gluing 8 to the positioning pins 10 in the final stage, the laminated state is achieved. Retained.

As a result, the centrifugal blower impeller 6 (
1■ be accomplished. When the centrifugal blower wheel 6 is rotationally driven, the static pressure increases as the circumferential velocity increases toward the outer periphery of each air flow path 11, and the cross-sectional area of the air flow path 11 increases toward the outer periphery. As a result, static pressure increases due to a decrease in flow velocity, which functions as a centrifugal blower impeller and sends the upper air from the inner circumference side to the outer circumference side.The annular plate 8 and the corrugated plate 9 have the following features. The deodorizer is supported in the following manner. That is, as shown in FIG. 4, the annular plate 8 and the corrugated plate 9 have short fibers 12 flocked on their surfaces. This fiber 12 has a diameter of 0.05 m and a length of 0.05 m.
Approximately 3 fins, both 11ij8. 9 is tightly adhered to the entire surface without any gaps. Then, apply a deodorizing liquid (for example, "Fresh Shiraimatsu" (trademark) manufactured by Shiraimatsu Shinyaku Co., Ltd., which is made from plant-extracted deodorizing ingredients) to the 12 areas of the flocked hair.
) is soaked and dried, thereby making the deodorizer adhere to the entire surface of the annular plate 8 and the corrugated plate 9. As a result, the inner surface of the air flow path 11 of the centrifugal blower 6 is in a state where the deodorizing agent is supported on the entire surface. can.

As shown in FIG. 1, the centrifugal blower wheel 6 configured as described above has its center portion located just inside the air intake port 2 and is disposed approximately in the center of the main body case 1. It is fixed to the rotating shaft 4a with a screw 13.

Next, the operation of the above configuration will be explained. When an operation switch (not shown) is turned on, the centrifugal blower wheel 6 is rotationally driven by the motor 4, and this draws air from the center side. As a result, air outside the main body case 1 , that is, inside the room, is sucked in through the intake port 2 and sent to the center side of the centrifugal blower wheel 6 .

This air flows into a large number of air channels 11 of the rotating centrifugal blower wheel 6, and is flown through the air channels 11 toward the outer circumference. During this time, odor components contained in the air are absorbed by the deodorizer attached to the inner surface of the air flow path 11 and deodorized. Thereafter, the deodorized air flowing out from the air flow path 11 is discharged to the outside (indoor) through the exhaust port 3. In this way, indoor air is continuously taken in and discharged, and eventually the entire indoor air is deodorized.

Incidentally, when the deodorizing ability of the deodorizing agent decreases due to long-term use, it is sufficient to loosen the screw 13, remove the centrifugal blower wheel 6, and replace it with a new one.

According to this embodiment, the number of air flows Wll is significantly increased due to the structure of the centrifugal blower impeller 6.
The cross-sectional area of the air flow path 11 as a whole becomes sufficiently large, and the flow velocity of the air within the air flow path 11 can be suppressed while ensuring a sufficient amount of air flow. Along with this, the air flow path 11
Since the overall internal area is sufficiently large, the deodorizer is applied over a wide area. Therefore, the air flows through the air flow path 11 to which the deodorizer is attached over a wide area.
Since the deodorizer flows slowly through the air, good contact between the odor components in the air and the deodorizer is achieved.

As a result, good deodorizing performance is obtained, and since a sufficient exhaust amount is ensured as described above, indoor air can be deodorized with high deodorizing efficiency.

In addition, since the centrifugal blower wheel 6 has a blowing function and also has a deodorizing function, it requires a space for installing a blower and a space for a filter, as in conventional ones. Unlike the above, a motor 4 and a centrifugal blower wheel 6
All you need is enough space to place the □. Therefore, in addition to having the above-mentioned high deodorizing efficiency, it is possible to downsize the device. In particular, in this embodiment, since the bulge 7a surrounding the motor 4 is formed in the center of the centrifugal blower wheel 6, the device as a whole can be further downsized.

In the above embodiment, both the annular plate 8 and the corrugated plate 9 carry the deodorizing agent, but only one of them may carry the deodorizing agent. Further, the deodorizing agent may be granular activated carbon or the like, and in this case, it may be attached using an adhesive. Further, the annular plate and the corrugated plate may be formed of a fibrous material such as corrugated paper and impregnated with the deodorizing liquid.

In addition, various modifications can be made to the present invention without departing from the scope of the invention.

[Efficacy of invention! ! ! ] As is clear from the above description, according to the deodorizing device of the present invention, the blower impeller is a centrifugal blower impeller having a large number of air flow paths connecting the inner and outer circumferences by stacking annular corrugated plates. At the same time, the inner surface of the air flow path of this centrifugal blower impeller carries a deodorizing agent that removes odor components in the air, so it has good deodorizing performance and a sufficient exhaust volume, resulting in high deodorizing efficiency. Moreover, it has the excellent effect of making it possible to downsize the entire device.
