  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 shows an external perspective view of the present embodiment. The main body case 1 of the dehumidifying device has a box shape, has a substantially rectangular air outlet 2 at the top, and has an intake panel 5 at the front. By combining the main body case 1 and the intake panel 5, a suction port 3 is formed on the side of the main body case 1. Further, a tank 6 is provided at the lower part of the main body case 1. Further, an operation unit 4 is provided at the upper part, and the user can operate the dehumidifying device by operating the operation unit 4, and sucks indoor humid air from the suction port 3. Dehumidification is performed in the case 1 and returned to the room as dry air from the air outlet 2. The dehumidified moisture becomes water droplets and is stored in the tank 6.

  2 is a schematic cross-sectional view taken along the line AA in FIG. 1, and FIG. 3 is an exploded perspective view. Inside the main body case 1, a fan 7 that takes in indoor air from the inlet 3 and blows it to the outlet 2, a disk-like rotor 8 that absorbs moisture from the indoor air, and a drive means 9 that drives the rotor 8 to rotate. The circulation path 10 is provided. The circulation path 10 is formed so that the regeneration air is circulated through a part of the rotor 8, a circulation fan 11 that circulates the regeneration air in the circulation path 10, and a heater 12 that releases moisture from the rotor 8 in the circulation path 10. And a condenser 13 for condensing moisture by exchanging heat between the regenerated air containing moisture released from the rotor 8 and the indoor air supplied by the fan 7.

  The main body case 1 is provided with a suction port 22, and air flowing in from the suction ports 3 on both side surfaces is taken into the main body case 1 from the suction port 22. A filter 14 for filtering out dust and the like in room air is provided outside the suction port 22, and an intake panel 5 is provided outside the filter 14.

  The rotor 8 is configured by supporting a hygroscopic material such as zeolite or silica gel on a substrate such as a honeycomb-shaped ceramic paper, and is configured in a disk shape. The rotor 8 absorbs moisture and releases moisture. It is divided into wet areas. And it is comprised so that a moisture absorption and moisture release may be repeated continuously by exchanging a moisture absorption area | region and a moisture release area | region sequentially by rotating.

  The drive means 9 is composed of a small motor or the like, and is combined with the rotor 8 via a gear or the like to drive the rotor 8 to rotate.

  The circulation fan 11 is configured as a so-called sirocco fan that combines a motor and an impeller, and circulates air in the circulation path 10.

  The heater 12 is made of a material that generates heat when energized, such as a nichrome wire, and heat is released from the rotor 8 in the moisture release region of the rotor 8.

  The condenser 13 is a heat exchanger in which a plurality of heat transfer plates that transmit heat of resin or metal are combined, and has a wind path through which the regenerated air of the circulation path 10 flows and a wind path through which room air flows. It is comprised so that heat may be exchanged between these air paths. When the high-temperature and high-humidity regeneration air is cooled to the room air, moisture is condensed and taken out as water droplets.

  The fan 7 is configured as a so-called sirocco fan in which an impeller rotates and blows air in a casing, and takes in indoor air from the suction port 3 into the main body case 1. A dehumidifying air passage 15 that is introduced into the rotor 8 to remove moisture and a cooling air passage 16 that is introduced into the condenser 13 and cools the condenser 13 are formed. Then, the air from each air path is mixed from the blower outlet 2, and it blows so that it may blow off. The rotor 8 and the condenser 13 are juxtaposed in the horizontal direction on the long side of the main body case 1. Thus, the air sucked from the suction port 3 is diverted to each of the rotor 8 and the condenser 13 and flows in parallel in the short side direction of the main body case 1, so that the air passage area can be increased and the air passage distance is short. Therefore, the in-machine ventilation resistance can be reduced with respect to the required air volume, and as a result, effects such as noise reduction due to the ventilation resistance and downsizing of the fan 7 can be obtained.

  The dehumidifying operation in the above configuration will be described. Room air is sucked from the suction port 3 by the fan 7, moisture is absorbed by the moisture absorption region of the rotor 8, and the dehumidified air is blown into the room from the outlet 2 as dry air (dehumidification air passage 15). Moisture absorbed by the rotor 8 moves to the moisture release region by the rotational drive of the rotor 8, and is released to the circulation path 10 by the heating of the heater 12. In the circulation path 10, the hot and humid air sent from the rotor 8 is blown to the condenser 13 by the blowing of the circulation fan 11. In the condenser 13, heat is exchanged between the circulation path 10 and the cooling air path 16 that cools the condenser 13 sucked into the main body case 1 by the fan 7, and the high-temperature and high-humidity air in the circulation path 10 is cooled to condense the moisture. It is recovered as water. The air in the cooling air passage 16 that has cooled the condenser 13 and increased in temperature is mixed with the air in the dehumidifying air passage 15 by the fan 7 and blown into the room from the air outlet 2. In this way, the indoor air dehumidifying operation is performed.

  Details of the circulation path 10 will be described. FIG. 4 is a schematic view of the internal configuration viewed from the fan 7 side, and FIG. 5 is a schematic view of the internal configuration viewed from the suction port 22 side.

  The air blown by the circulation fan 11 is heated by the heater 12, becomes high temperature, and is introduced into the rotor 8. Here, by releasing moisture from the rotor 8 containing moisture, the rotor 8 is regenerated to a state where moisture can be adsorbed again. The air that contains a lot of moisture after passing through the rotor 8 and becomes hot and humid is blown upward, and is blown upward of the rotor 8 toward the condenser 13. In the condenser 13, the air in the circulation path 10 flows from the upper side to the lower side, and heat exchange is performed with the indoor air passing in the horizontal direction. The hot and humid air becomes saturated by being cooled, and moisture is condensed. The air that has become saturated due to the condensation of moisture passes under the rotor 8 and is sucked into the circulation fan 11. In the air passage that passes below the rotor 8, the water receiver 17 that collects condensed water droplets serves as a part of the air passage. The condensed water droplets are collected by the water receiver 17 and guided to the tank 6.

  As shown in FIG. 5, this embodiment is characterized in that heat exchange promoting means 18 for promoting heat exchange with the air supplied by the fan 7 to the circulation path 10 is provided.

  That is, in the air passages other than the condenser 13 in the circulation path 10, the heat exchange with the room air is promoted, so that the condensation of the circulating air is promoted also outside the condenser 13 and more moisture is taken out.

As shown in FIG. 5, by providing the heat exchange promoting means 18 at the place facing the suction port 22 of the main body case 1 of the circulation path 10, the heat exchange between the air in the circulation path 10 and the room air is promoted, It is possible to promote the condensation of the circulating air. Then, the air having a reduced moisture content can be introduced into the heater 12, and the air after being heated by the heater 12 can be in a more dry state, and the regeneration capability when the rotor 8 is regenerated is improved. As a result, the adsorption performance of moisture from room air is also improved. As a result, it is possible to provide a dehumidifying device capable of improving the dehumidifying ability.

  Further, the heat exchange promoting means 18 is provided in the circulation path 10 from the condenser 13 to the heater 12.

  That is, in the circulation path 10, the portion from the condenser 13 to the heater 12 is a portion after moisture condensation in the condenser 13, so that the relative humidity of air is in a saturated state close to 100%. By providing the heat exchange accelerating means 18 in this part, all of the heat exchanged heat can be utilized for moisture condensation, and condensation can be promoted efficiently. As a result, it is possible to provide a dehumidifying device capable of improving the dehumidifying ability.

And the heat exchange promotion means 18 is provided with the water droplet guidance | induction part 19 which guides the water droplet which condensed on the wall to the lower part.

  That is, if a water droplet stays on the wall, the attached water droplet becomes a thermal resistance, and the heat exchange between the indoor air and the circulating air through the wall is hindered. In this way, by actively guiding the water droplet to the lower portion by the water droplet guiding section 19, it is possible to suppress the water droplet from remaining on the wall and to promote heat exchange. Further, since the lower part of the circulation air passage is configured as a water receiving portion 17 that leads water droplets to the tank as they are, the water droplets are smoothly collected and led to the tank 6. As a result, it is possible to provide a dehumidifying device capable of improving the dehumidifying ability.

  Further, a plurality of grooves 20 extending in the vertical direction are provided in the circulation path 10.

  That is, by providing the groove 20, the cross section of the wall partitioning the room air and the circulating air becomes uneven, and the area of the wall increases. That is, the area of the heat transfer surface for transferring heat increases, and heat exchange can be promoted. Furthermore, by forming a groove shape in the vertical direction, water droplets generated on the wall will be promoted to drop downward along the groove, and it is possible to suppress water droplets from staying on the wall and heat exchange. Can be promoted.

  As a result, it is possible to provide a dehumidifying device capable of improving the dehumidifying ability.

That.

  That is, in the air passages other than the condenser in the circulation path, the heat exchange with the room air is promoted, so that the condensation of the circulation air is promoted even outside the condenser, and more water can be taken out. By providing the heat exchange promoting means at the place facing the suction port of the main body of the circulation path, heat exchange between the air in the circulation path and the room air can be promoted, and condensation of the circulation air can be promoted.
