Description
DEHUMIDIFYING DRIER APPARATUS
The invention relates to dehumidifying drier apparatus, and more specifically, to a heater for drying off absorbed moisture in a dehumidifying rotor in the apparatus.
In a dehumidifying drier apparatus including a conventional dehumidifying rotor and a conventional heater, the heater in its heating unit, for heating rotor-revitalizing air being sent to a revitalization portion of the dehumidifying rotor, is made approximately sectoral in form as a whole, corresponding to the revitalization portion of the dehumiditring rotor.
The heater is made with coiled nichrome wires, each folded like a winding road, and installed in two layers interleaved with three sheets of insulating material that flare radially (Japanese Patent Laid-Open No. H11-300144 (page 3 through page 5, and Fig. 2 through Fig. 13)).
The conventional heater configured as described above must be made approximately sectoral in form as a whole, in which the coiled nichrome wires, each folded like a winding road, are installed in two layers. l
Therefore, a lot of man-hours have been required in manufacturing, mounting and processing the heaters.
The present invention has been made to resolve such a problem, and aims to realize a dehumidifying drier apparatus that makes it easy to manufacture, mount and process the heater for drying a dehumidifying rotor, and that leaves no undried portion in the revitalization portion of the dehumidifying rotor.
A dehumidifying drier apparatus relevant to the present invention prepares dry air by passing air to be dehumidified through a dehumidifying I rotor, being a rotating body including a absorbent material for absorbing moisture, to cause the rotor to absorb moisture in the air to be dehumidified, and passes heated air, prepared in a heater, through the dehumidifying rotor having absorbed moisture, to dry the dehumidifying rotor. The heater is disposed in the vicinity of the dehumidifying rotor upstream in the heated air's airflow passage, and is configured so that the distance between the heater and the heated-air passing surface of the dehumidifying rotor! gradually increases heading from the circumferential side of the dehumidifying rotor radially toward its center.
Because, in the dehumidifying drier apparatus according to the invention, the heater is disposed so that the distance from the dehumidifying rotor gradually increases heading from the circumference to the center, a heater with a simple structure stretching Mom the circumferential side of the dehumidifying rotor radially toward its center can be disposed at a slant, and it is easy to manufacture, mount and process the heater. In addition, because the velocity is varied according to radial positions from the rotational center due to rotation of the dehumidifying rotor, nonuniform drying is likely to occur. However, the heater is disposed so that the distance between the heater and the dehumdibing rotor gradually increases heading from the circumferential side toward the center as in the invention, whereby nonuniform drying can be prevented, and the moisture in the revitalization portion of the dehumidifying rotor can be uniformly dried without portions remaining undried.
The invention will be further described by way of non-limitative example with reference to the accompanying drawings, in which: Fig. 1 is a schematic diagram illustrating the internal structure of a dehumidifying drier apparatus in Embodiment 1 of the present invention.

Embodiment 1.
Fig. 1 is a schematic diagram illustrating the internal structure of a dehumidifying drier apparatus according to Embodiment 1 of the present invention, Fig. 2 is a perspective view illustrating an arrangement of a heater with respect to a dehumidifying rotor in the dehumidifying drier apparatus in Fig. 1, and Fig. 3 is a side view illustrating the arrangement of the heater with respect to the dehumidifying rotor in Fig. 1.
In Fig. 1, the dehumidifying drier apparatus houses, in its chassis, a condenser 1 for condensing moisture in rotor-revitalizing air, a dehumidifying rotor 2 that is a rotating moisture-absorbing body for passing therethrough air to be dehumidified, which is indoor air, to absorb moisture in the air, a heater 3 for heating the rotorrevitalizing air, a blower fan for taking in the air to be dehumidified, which is indoor air, from an intake (not illustrated) of the chassis, and for blowing it out into the room as dry air through an outlet (not illustrated of the chassis, a water storage tank 5 for storing water condensed by the condenser 1, a revitalizing air channel 7, formed by the wall, through which rotor-revitalizing air is circulated by a revitalizing-air-channel blower fan 6, and a motor 8 for driving the blower fan 4.
The dehumidifying rotor 2 is a rotating disk rotated by a dehumidifyingrotor rotating motor (not illustrated in the figure), holds moisture absorbent material such as zeolites thereon, and has air permeability that allows air to distribute through the disk face of the rotating disk. Moreover, the dehumidifying rotor 2 is composed of a dehumidifying portion 2a through which the air to be dehumidified is passed, and which absorbs moisture Mom the air to be dehumidified, and of a revitalization portion 2b through which the rotor-revitalizing air that is heated air heated by the heater 3 is passed so that the moisture is removed as evaporated moisture.
The condenser 1 is a portion of the revitalizing air channel 7, in which the warm and moist rotor-revitalizing air in the revitalizing air channel 7, that has passed through the revitalization portion 2b of the dehumidifying rotor 2 and that has evaporated the moisture absorbed in the revitalization portion 2b, and the indoor air outside of the revitalizing air channel 7, which has been taken in from the intake, carry out heat exchange, whereby the warm and moist rotor-revitalizing air in the revitalizing air channel 7 is cooled, so that the moisture is condensed.
Along the revitalizing air channel 7, the dehumidifying rotor 2 is rotatably installed, with the rotor-revitalizingair passing surface being perpendicular to the direction of the rotorrevitalizing air flow. An aperture section of the revitalizing air channel 7, in which the dehumidifying rotor 2 is installed, is an elongated form such as an approximate rectangle, facing the dehumidifying rotor 2 Mom the circumferential side toward the center of the dehumidifying rotor 2. The aperture section is formed so as to correspond to the outer shape of a later-described rod heater 3a as a heater 3. And, the portion of the dehumidifying rotor 2, corresponding to the aperture section of the revitalizing air channel 7, more specifically, the portion through which the heated air Tom the aperture section passes, and which is irradiated with radiation heat from the heater 3, is the revitalization portion 2b of the dehumidifying rotor 2. The remaining portion thereof, more specifically, the portion through which the air to be dehumidified passes, is the dehumidifying portion 2a.
In addition, under the revitalizing air channel 7, a communicating channel for draining water condensed by the condenser 1 to the water storage tank 5 in the lower portion of the chassis is formed. The moisture condensed in the condenser 1 is stored in the water storage tank 5 via the communicating channel.
Next, an arrangement of the heater 3 with respect to the dehumidifying rotor 2 will be described according to Fig. 2 and Fig. 3.
Re-release of moisture by heating the dehumidifying rotor 2 is performed b both "radiation heats' and "passage of heated air". The percentage of the eYect of "radiation heat" is relatively smaller than that of the moisture release effect of Passage of heated air".
In the present embodiment, a U-shaped rod heater 3a is used for the heater 3. The rod heater 3a is installed so that the plane containing its U shape faces the revitalization portion 2b of the dehumidifying rotor 2. In addition, one end (lead wire side) of the longitudinal direction of the heater 3 is disposed facing the circumferential side of the dehumidifying rotor 2, and the other end is disposed facing the rotational center of the dehumidifying rotor 2. Because the dehumidifying rotor 2 is a rotating body, the velocity is different according to the distance from the rotational center.
More specifically, the more apart from the rotational center, the faster the velocity, and the closer to the rotational center, the slower the velocity.
Therefore, if the heater 3 is disposed in parallel to the rotorrevitalizing-air passing, face of the dehlTnidifying rotor 2, nonuniform drying arises. In the embodiment, the heater 3 is disposed at a slant so that the distance from the revitalization portion 2b of the dehumidifying rotor 2 decreases toward the circumferential side of the dehumidifying rotor 2, and increases toward the rotational center. Accordingly, because the distance to the rod heater 3a is small in the circumferential side of the dehumidifying rotor 2, the heated air passes through the dehumidifying rotor 2 with its high temperature kept, and because the distance to the rod heater 3a is large in the low-speed central side, the heated air passes through the dehumidifying rotor 2 with its temperature slightly reduced.
Moreover, because the radiation heat generated from the rod heater 3a irradiates from the rod heater 3a to the revitalization portion 2b of the dehumidifying rotor 2, the larger the distance between the dehumidifying rotor 2 and the rod heater 3a, the more the amount of irradiation heat F om the- heater 3a to the dehumidifying rotor 2 decreases.
For this reason, because the distance between the circumferential side of the dehumidifying rotor 2 and the rod heater 3a is small, and heated air having a large amount of irradiation heat with a high temperature passes through the circumferential side, the circumferential side moves at high speed, but is heated during a short period of time. Although, through the central side of the dehumidifying rotor 2, heated air having a small amount of irradiation heat with a temperature lower than the circumferential portion passes, the central side is heated during a relatively long period of time because it moves at low speed. In other words, the revitalization portion 2b of the dehumidifying rotor 2 is heated uniformly throughout the radial direction.
In addition, the rod heater 3a is disposed so as to face the revitalization portion 2b of the dehmidify-ing rotor 2, but so as not to contact with the dehumidifying rotor 2.
In the dehumidifying drier apparatus, the indoor air taken in from the intake, which is the air to be dehumidified, passes through the dehumidifying portion 2a of the dehumidifying rotor 2, whereby its moisture is removed, and the dehumidified air blows out as dry air from the outlet into the room.
Meanwhile, the dehumidifying portion 2a of the dehumidifying rotor 2, that has absorbed moisture, moves to the revitalization portion 2b due to its rotation, and is dried by the high temperature heated air heated by the heater 3 (rod heater 3a) passing therethrough. At this conjuncture, because
S
the rod heater 3a is disposed at a slant with respect to the revitalization portion 2b of the dehumidifying rotor 2, nonuniform drying caused by the variance in velocity according to the distance from the rotational center, due to the rotation of the dehumidifying rotor 2, can be prevented, and the 6 moisture in the revitalization portion 2b can be uniformly dried without leaving undried portions.
Moreover, a heater with a simple structure stretching radially from the circumferential side of dehumidifying rotor 2 toward the center can be disposed at a slant to be used for the heater 3 Furthermore, the aperture shape of the aperture section of the revitalizing air channel 7 can be a simple rectangular shape. Thus, the heater 3 is easy to manufacture and install.
Fig. 4-is a diagram illustrating measurement results of the surface temperature distribution of the dehumidifying portion 2a in the dehumidifying rotor 2 when the dehumidifying drier apparatus is running.
The horizontal axis is the distance from the rotational center of the dehumidifying rotor 2, and the vertical axis is the surface temperature of the dehumidifying rotor 2 in steady running. As illustrated in Fig. 4, according to the invention, regarding the surface temperature t of the dehumidif King rotor 2, a radially uniform temperature from the distance R1 through the distance R2 apart from the rotational center of the dehumidifying rotor 2 can be realized.
Moreover, another heater separated from the heater 3 irradiating radiation heat to the dehumidifying rotor 2 can be used for a heater 3 for preparing heated air, which is rotorrevitalizinb air, and the same effects can be obtained.
Furthermore, the aperture shape of the aperture section of the revitalizing air channel 7 is not limited to a simple rectangle that is radially elongated, but can be an approximate sectoral form along the shape of the disk of the dehumidifying rotor 2. If the aperture is made approximately sectoral in form, by appropriately configuring the area of the aperture, radial nonuniformity in heated-air drying, between the circumferential side and the center of the rotor, can be reduced.
Embodiment 2.
Fig. 5 is a perspective view illustrating an arrangement of a heater with respect to a dehumidifying rotor in a dehumidifying drier apparatus in Embodiment 2, and Fig. 6 is a side view also illustrating the arrangement of the heater with respect to the dehumidifying rotor. Fig. 5 and Fig. 6 are diagrams corresponding to Fig. 2 and Fig. 3 in Embodiment 1, respectively.
Although the heater 3 in the dehumidifying drier apparatus in Embodiment 1 is linearly inclined, the heater 3 in the present embodiment is inclined describing a curve. Because the configuration and the flue of the other components are similar to those in Embodiment 1, the differences will be mainly described below.
The heater 3 in the present embodiment is configured in the manner in which, in the U shaped rod heater 3a in Embodiment 1, the linear portions of the U shaped body are continuously curved (curved in a circular arc in the example of Fig. 5 and Fig. 6) longitudinally from one end (an end facing the circumferential side of the dehumidifying rotor 2) to the other end (an end facing the rotational center of the dehumidifying rotor 2) so that the side opposing the dehumidifying rotor 2 is concave. More specifically, in Embodiment 1, the rod heater 3a is linearly inclined with respect to the face of the revitalization portion 2b of the dehumidifying rotor 2 so that the distance between the two increases radially from the circumferential side toward the rotational center, while in the present embodiment, a curved heater 3b that is inclined in a curved fashion is used.
In the present embodiment, because the curved heater 3b is disposed to be inclined describing a curve with respect to the face of the revitalization portion 2b of the dehumidifying rotor 2 so that the distance between the. two increases from the circumferential side of the dehumidifying rotor 2 toward the rotational center, nonuniform drying caused by the variance in velocity according to the distance from the center of the dehumidifying rotor 2 can be prevented as in Embodiment 1. In addition, in the present embodiment, even if there are variance in air volume along a radius of the dehumidifying portion 2a, which is variance in atmospheric condition of the air to be dehumidified, and variance in air volume or temperature along a radius of the revitalization portion 2b, which is variance in atmospheric condition of the heated air7 in other words, even if there is variance in moisture absorbing amount along a radius of the revitalization portion 267 according to atmospheric conditions of air to be dehumidified and to atmospheric conditions of heated air heating in accordance with conditions becomes easy by selecting the curvature, so that nonuniform drying can be prevented, and moisture in the revitalization portion 2b can be uniformly dried without leaving undried portions.
Moreover, if the heater 3 is installed in a state slanted to vary in consideration of velocity variance according to distance variance from the center due to the rotation of the dehumidifying rotor 2, and radial variance in atmospheric condition of the air to be dehumidified in the dehumidifying portion 2a of the dehumidifying rotor 2 and/or radial variance in atmospheric condition of the heated air in the revitalization portion 2b of the dehumidifying rotor 2, then the dehumidifying drier apparatus can uniformly dry moisture in the revitalization portion 2b more effectively without leaving undried portions. 1 _
