Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to steam processing for equipment that generates steam, such as rice cookers, and particularly relates to a built-in device that dehumidifies the steam generated.

Prior Art A conventional example is shown in FIG. In FIG. 3, when a double-blade fan 1 with functions of air blowing and heat exchange is rotated by a motor 6, a cooling side casing 3 is separated by a partition plate 2.
Air flows a and b are generated within the dehumidifying casing 4.

Here, a and b indicate the flow of cooling air and humid air, respectively.

The hot and humid outside air C flowing in through the intake hole 7 is circulated through the separator 8 in the dehumidifying side casing 4 as shown by the arrow, and is cooled by the cooling air a in the blade portions 9 of the double-wing fan 1. , dehumidified. Moisture that is cooled and condensed on the surface of the blade portion 90 is drained from the drain hole 5 provided at the lower part of the separator 9. The upper part of the drain hole 6 is sloped near the opening 10 so that condensed moisture flows into the drain hole 6.

Problems to be Solved by the Invention In such a conventional configuration, the humid air space in the dehumidifying side casing 4 flows through the separator 8 in a complicated circulation flow (arrow b).
) is occurring. Therefore, the upper part of the drain hole 5 is
When the slope of 0 is gentle, the force of the flow of cooled and condensed water toward the drain hole 5 is exceeded by the wind pressure of the humid air flow generated by the double-blade fan rotating 10 times, and the condensed water flows below the drain hole 5. Almost no water flows, and the upper part of the drain hole 6 in the dehumidifying side casing 4 remains in the opening 1o.
In some cases, it leaks into the cooling side casing 3 through the gap between the double-wing fan 1 and the partition plate 2.

In order to allow condensed water to flow smoothly toward the drain hole 6, if the upper part of the drain hole 6 is sloped steeply near the opening 10, the shape of the drain hole 6 will become complicated. There were other issues.

An object of the present invention is to provide a dehumidifying device that has a simple structure, allows smooth drainage without scooping up condensed water, and has a simple shape near the upper part of the drain hole 5.

Means for Solving the Problem A first invention for achieving the above-mentioned object is a dehumidifier in which the drain hole is located on the extension of the rotating outer circumference of both blade fans and in a straight line with the dehumidifying side casing side of the partition plate. This is a configuration that is installed at the bottom of the side casing.

In the second invention, a groove is provided on the inner peripheral surface of the dehumidifying casing, and a drain hole is provided in the lower part of the groove formed in the lower part of the dehumidifying casing.

Effect 5.＼ / With the configuration of the first invention, moisture that has been cooled and condensed by the blades of the double-blade fan is blown away by the action of centrifugal force around the rotating outer circumference of the double-blade fan, and further Moisture flows along the inner peripheral surface of the dehumidifying side casing due to the wind pressure effect of the flow generated by the rotation of the double-blade fan, and then flows down to the bottom of the casing due to moisture gravity, and is drained through the drain hole without stopping at the upper part of the drain hole. Therefore, as in the conventional example described above, the rotation of the double-blade fan scrapes up the standing water and allows it to be drained from the drain hole without leaking into the cooling side casing.

Next, with the configuration of the second invention, the water cooled and condensed by the blades of the double-blade fan is blown onto the inner peripheral surface of the dehumidifying side casing outside the rotating outer periphery by the rotational centrifugal force of the double-blade fan. , is collected in the groove provided on the inner peripheral surface, and as mentioned above, due to the wind pressure effect of the airflow due to the rotation of the double-blade fan and the water gravity, it flows down the groove to the lower part of the casing, and is drained smoothly through the drain hole. . Therefore, as described above, the retained water is not scraped up and leaked into the cooling side casing as in the conventional example.

Example Embodiments of the present invention will be described below based on the accompanying drawings.

FIG. 1 shows an embodiment of the first invention.

In FIG. 1, reference numeral 1 denotes a double-blade fan with functions of blowing air and heat exchange, and the outer periphery of the double-blade fan 1 and a partition plate 2 partition the fan into a cooling side casing 3 and a dehumidifying side casing 11. The cooling side casing 3 is provided with a cooling side intake hole 12 for sucking in cold air at the outer center thereof, and an exhaust hole 13 for discharging the air inside the cooling side casing 3 at the lower part thereof. The dehumidifying side casing 11 has a dehumidifying side intake hole 7 in the outer central part thereof for sucking in humid outside air C from the outside, and a separator 8 with holes formed in the central part facing the intake hole 7 and in the outer peripheral part is provided inside the dehumidifying side intake hole 7. The inside of the dehumidifying side casing 11 is divided into two rooms. Furthermore, a drain hole 14 is provided in the lower part of the dehumidifying casing 11 for draining dew condensation water generated within the dehumidifying casing 11. In the figure, d is the cooling air flowing through the cooling side casing 3, and e is the moist outside air C flowing through the intake hole 7.
It shows the humid air sucked in from the air and circulating through the separator 12 within the dehumidification side casing 11.

In the dehumidifier having the above configuration, when the double-blade fan 1 is rotationally driven by the motor 6, a pressure difference is created between the center and the outer circumference of the double-blade fan 1, and the center becomes negative pressure, resulting in air flows d and e. The humid outside air C sucked in through the intake holes 7 becomes a flow e, and is cooled and dehumidified by the action of heat exchange by the cooling air d in the blade section 9 of the double-blade fan 1. At this time, the drain hole 14 is located in the lower part of the dehumidifying casing 11, which is located on the extension of the outer peripheral part of the double-blade fan 1 and approximately in a straight line with the surface of the partition plate 2 on the dehumidifying casing 11 side. Since it is installed on the same extension as the two partition plates, it is cooled by the blade part 9,
The condensed water slowly flows into the drain hole 14 and is smoothly drained without remaining in the upper part of the drain hole 14 as in the conventional example. Therefore, unlike the conventional example, condensed water does not accumulate and is scooped up by the double-blade fan 1 and does not leak into the cooling side casing 3.

Next, an embodiment of the second invention is shown in FIG.

In FIG. 2, the same components as those in the first embodiment of the invention are given the same reference numerals and detailed explanations will be omitted.

The feature of this second invention is that a groove 16 is formed on the inner circumferential surface of the dehumidifying side casing 15, and a drain hole 17 is provided at the lower part of the groove for draining the condensed water generated by the dehumidifying action of the double-blade fan 1.
This is because we have established Note that one end of the edge of the groove 16 is connected to the corner formed by the partition plate 2 and the dehumidifying side casing 16 so that the moisture blown toward the outer circumference of the double-blade fan 1 can easily collect in the groove 16. There is.

In the dehumidifier having the above configuration, when the double-blade fan 1 is driven to rotate by the motor 6 or the like, air flows d.

The humid air generated by the cooling air d is cooled and dehumidified by the cooling air d in the blade section 9 of the double-winged fan 1.

9...7 At this time, since the groove 16 is provided on the inner peripheral surface of the dehumidifying side casing 15, the moisture dehumidified by the blade portion 9 of the double-blade fan 1 is transferred to the dehumidifying side casing 15 by the centrifugal force of the double-blade fan 10 rotation. is blown to the inner surface of the groove 16, and receives the rotational wind pressure of the double-blade fan 1.
Water is drained through the drain hole 17. Therefore, unlike the conventional example, moisture remains in the upper part of the drain hole 17 and is scraped up by the double-blade fan 1, and does not leak into the cooling side casing 3.

Note that, similarly to the first invention, the groove 16 is arranged on the inner circumferential surface of the dehumidifying side casing 15 between the partition plate 2 and the separator 80, adjacent to the partition plate 2, and a drain hole is provided in the lower part of the groove 16. 17, the condensed water can be drained smoothly.

Although the shape of the groove 16 is shown as approximately V-shaped in FIG. 2, there is no particular designation of the shape, and it may be U-shaped, for example.

Effects of the Invention As described above, by using the means of the first invention, moisture that is cooled and condensed by the blades of the double-blade fan is blown to the outer periphery of the rotation by the rotation of the double-blade fan. Further, due to the wind pressure effect of the flow caused by the rotation, it flows along the inner circumferential surface of the dehumidifying side casing, and is smoothly drained from a drain hole provided in a path on the outer circumferential extension of the rotation where condensed water can easily flow. Therefore, unlike the conventional example, the moisture remaining in the upper part of the drain hole is scraped up by the rotation of the double-blade fan and does not leak into the cooling side casing. Furthermore, the shape can be made simpler than the conventional example.

Moreover, by adopting the means of the second invention, moisture that is cooled and condensed by the blade portions of the double-blade fan is blown to the outer periphery of the rotation by the rotation of the double-blade fan, and is collected in the groove.
Further, due to the wind pressure effect of the flow caused by the rotation of the fan, the water flows smoothly down the groove provided on the inner peripheral surface of the dehumidifying side casing, and is drained through the drain hole. Therefore, as described above, condensed water is scraped up by the rotation of the fan and does not leak into the cooling side casing. Moreover, it can be made extremely simple in shape.
