Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifying / drying unit using a dehumidifying element.

[0002]

2. Description of the Related Art Conventionally, bathroom dryers are generally of the type that uses both heating with hot water or an electric heater and ventilation to discharge air in the bathroom (warm air ventilation drying system), or dehumidification using a refrigeration cycle. It was target. In the case of using hot water, there are problems that a boiler for hot water is required in addition to a drying unit installed in a bathroom, and that a system using a refrigeration cycle has a complicated structure and a large weight and external dimensions. In addition, since these systems are complicated, they are generally expensive systems and are generally installed on the ceiling of the bathroom.Installation is practically impossible until new construction or remodeling. It was hindering its spread to the bathroom.

[0003]

In the hot air ventilation drying method, since the air in the bathroom is discharged as it is, the heat loss due to the exhaust (especially when the clothes dried in the bathroom or the bathroom have a high dryness, the moisture is removed). Efficient drying because the heat loss due to the exhaust increases compared with the amount, and the heat loss from the bathroom wall or window increases even if the bathroom temperature becomes unnecessarily high due to continuous heating.) It was an obstacle to the operation. On the other hand, the heat pump type drying unit using the refrigeration cycle uses the waste heat of the condenser (reheats the dehumidified air that has passed through the evaporator), so the thermal efficiency is relatively good but the drying time is extremely long. The laundry does not dry well (it does not look like sun drying)
There were problems such as. Further, the hot water ventilation drying method requires a boiler and the heat pump type uses a refrigeration circuit, so that the structure is complicated and the system is relatively expensive. In addition, since these devices are generally embedded in the ceiling, they are often difficult to introduce into existing houses, and there is a potential demand for drying bathroom clothes, but this has been a hindrance to the spread. Further, from the viewpoint of the recent CFC problem, a system for dehumidifying and drying without using a refrigeration cycle is also a socially required technology. Therefore,
It is an object of the present invention to provide a dehumidifying / drying unit which is compact and functional and which can be directly installed in a room.

[0004]

In order to achieve the above object, the present invention comprises a heater and a dehumidifying element in a case, and dehumidifies air passing through the heater and the dehumidifying element.
In a dehumidifying / drying unit for drying, a case is provided with a suction port, a blowout port, and an exhaust port, and a ventilation path connecting the suction port to the blowout port is provided with a heater and a dehumidifying element, and the heater and the dehumidifying element are provided. The secondary side of the above is provided with an exhaust damper that directs the air passing through these to the exhaust port. Further, according to the present invention, a ventilation port is further provided in the case, the heater and the dehumidifying element are provided upstream of the heater and the dehumidifying element is bypassed, and the air from the suction port is directly directed to the ventilation port. It is characterized by having a ventilation damper. Furthermore, the present invention is characterized in that the suction port and the air outlet of the case are directly opened in the room where dehumidification and drying are performed. In addition, the air sucked from the suction port bypasses the heater and the dehumidifying element and is exhausted from the ventilation port, or the heater that operates the sucked air and the dehumidifying element are passed. After the regeneration operation for discharging from the exhaust port, the heater that does not function the air sucked through the suction port, and the dehumidifying element to start the dehumidifying operation that blows out from the outlet. is there. Furthermore,
The present invention comprises a plurality of dehumidifying elements in the above case,
Each of the dehumidifying elements independently plays a role of dehumidifying and drying the room.

[0005]

According to the present invention, when the air in the room circulates, first, the air in the room is sucked into the case through the suction port, the moisture is adsorbed by the dehumidifying element in the ventilation passage, and the air is discharged. Is blown from and is returned to the room. However,
When the exhaust damper is switched, the air in the room that has passed through the heater and the dehumidifying element is exhausted from the exhaust port, whereby the dehumidifying element has its moisture removed and is regenerated. Further, when the ventilation damper is switched, the air from the room bypasses the heater and the dehumidifying element and is exhausted from the ventilation port, whereby the room is ventilated. Since various devices are compactly integrated in the case, if the inlet and outlet of the case are directly opened in the room to be dehumidified and dried, the case can be directly connected to, for example, a ventilation fan frame. As a result, this unit can be easily constructed even if it is not newly built or remodeled. If a plurality of dehumidifying elements are provided in the case, it is possible to dehumidify and dry the room using the other dehumidifying element while regenerating one dehumidifying element, and vice versa. It is possible to dehumidify and dry the inside of the room by utilizing one dehumidifying element while regenerating the dehumidifying element.

The dehumidifying / drying unit 100 according to this embodiment has a compact design and can be attached to, for example, a ventilation fan attachment frame without duct work. Dehumidifying / drying unit 1
As shown in FIGS. 2 and 3, 00 includes a case 10, and the case 10 is provided with a suction port 11, a blow port 13, a ventilation port 15, and an exhaust port 17. Further, the case 10 is provided with a partition wall 21 for partitioning the inside in the longitudinal direction and a partition wall 23 for partitioning in the lateral direction, and a ventilation path partitioned by these, that is, from the suction port 11 to the outlet port 13.
In the ventilation passage 25 connected to, a dust removing filter 26 for removing cotton dust and the like from the primary side, a heater (heater) 27, and a dehumidifying element 29 are arranged. 31 is a blower. As shown in FIG. 4, the dehumidifying element 29 is a ceramic honeycomb laminated body, includes a liner portion 29a and a flute portion 29b, and adsorbs moisture on the entire surfaces of the liner portion 29a and the flute portion 29b. These are made of a material obtained by polymerizing a metal silicate gel in a ceramic honeycomb laminate. The metal silicate gel is, for example, a combination of silica gel and a plurality of metals such as cobalt, iron, and manganese. As is apparent from FIG. 3, an electric ventilation damper 33 is provided on the primary side of the heater 27, and when the damper 33 reaches the position a, the air from the bathroom 1 is driven by the dehumidifying element 29 and the like. Instead of passing through, it is directly discharged to the outside through the ventilation port 15. If operated in this state, the bathroom 1 is ventilated. Further, two electric exhaust dampers 35 are provided on the secondary side of the dehumidifying element 29. Each of the dampers 35 reaches the position a, and the damper 33
