Abstract

PURPOSE:To improve the recovery efficiency of removed water by providing a plurality of groove extending radially in the same direction as that of rotation of a double-vane fan on the side, facing a circulation side, of a partition plate which separates the fan into a circulation side and a cooling side. CONSTITUTION:A double-vane fan 1, which is driven by a motor 5 and has a function of ventilation and heat exchange, is divided into a circulation side and a cooling side by means of a partition plate 2. The fan is is enclosed by a circulation side casing 4 and a cooling side casing 3. A plurality of grooves 6 extending radially in the same direction as that of rotation of the fan 1 are provided on the side, facing the circulation side, of the plate 2. By this simple construction, the moisture which is condensed by heat exchange and attached to the side of the plate 2, facing the circulation side, is prevented from seeping to the cooling side, facilitating the recovery of the moisture, resulting in improved recovery of removed water.

In FIG. 5, the motor 41 is driven and the double-wing fan 42 is driven.
rotates, and air flows C and d are generated in the cooling side casing 44 and circulation side casing 45, which are separated by the partition plate 43. Here, c and d indicate the flow of cooling air and circulating air, respectively. The hot and humid circulating air is cooled and dehumidified by the cooling air in the blades of the double-winged fan 42. In this way, the hot and humid air is dehumidified. At this time, the structure of the partition plate 43 is a disk-shaped flat plate as shown in FIG.

(Problems to be Solved by the Invention) In the above conventional configuration of the partition plate 43, when the dehumidifier is used horizontally, that is, when the double-blade fan 42 is used horizontally, the difference in pressure between the circulation side and the cooling side is equal to the difference in temperature. This occurs due to steam pressure and the pressure on the circulation side increases. In such a state, if moisture condensed through heat exchange in the blades of the double-blade fan 42 adheres to the circulation side surface of the partition plate 43, it will rotate while remaining attached to the circulation side surface of the partition plate 43 according to the rotational direction of the double-blade fan 42. However, there is a drawback that the dehumidified water leaks from the gap between the double-wing fan 42 and the partition plate 43 to the cooling side due to the pressure difference, and the recovery rate of dehumidified water decreases.

In the dehumidifying process as described above, water droplets condensed through heat exchange by the blades of the double-blade fan 1 are blown to the outer periphery of the fan by the rotational force of the double-blade fan 1. The water droplets adhering to the circulation side surface of the partition plate 2 flow concentrically in the rotational direction of the double-blade fan 1 due to the force of the circulating air. However, since the grooves 6 are present, these water droplets enter the grooves 6 due to capillary action, and flow further toward the outer circumference along the grooves 6 due to the force of the circulating wind. As a result, water droplets adhering to the partition plate 2 quickly flow toward the outer circumference, thereby preventing water droplets from leaking to the cooling side and improving the recovery rate of dehumidified water.

In FIG. 3, the drawings and explanations of the parts having the same configuration as the embodiment of the first means shown in FIG. 1 will be omitted. In the figure, 2 is a partition plate, 4 is a circulation side casing, and 7 is a tongue provided at the exhaust port of the circulation side casing 4. In this configuration, one of the plurality of grooves 6 provided in the partition plate 2 is located close to the tongue 7.

With the above configuration, the effect of the first means is of course achieved. In addition, the circulation air flow path is the narrowest near the tongue 7 of the exhaust port of the circulation side casing 4, so the flow velocity is high, and furthermore, the back surface of the tongue 7, that is, near the starting point of the circulation side casing 4, is under negative pressure. A part of the circulating air is not exhausted from the exhaust port but is drawn into the back side of the tongs 7 and circulated again. As a result of the above, the water droplets also try to circulate inside the circulation side casing 4 together with the circulating air, but since the groove 6 is located near the tongue 7, the water droplets also enter the groove 6 there due to capillary action. The force of the circulating air causes the air to flow along the grooves 6 toward the exhaust port of the circulation-side casing 4. Therefore, the dew condensation water is prevented from circulating inside the circulation side casing 4 again, the water droplets quickly flow toward the exhaust port, and the recovery rate of dehumidified water can be further improved.

(Effects of the Invention) With the configuration of the first means as described above, water droplets attached to the circulation side of the partition plate are moved to the outer circumference of the circulation side casing by the force of circulation air generated by the rotation of the double-blade fan and the grooves. It can be flushed quickly. Therefore, it prevents water droplets from leaking to the cooling side, improves the recovery rate of dehumidified water, and prevents the cooling air exhaust from becoming high humidity, so if you use this dehumidifier, there will be no condensation due to the cooling air exhaust.
