There is a filter 54 behind a case 51 in a body of the dehumidifier 50, a heat exchanger 60 in front of the filter 54 for carrying out a dehumidifying action, and a fan 70 in front of the heat exchanger 60. That is, the room air flows from the rear of the dehumidifier, is dehumidified at the heat exchanger 60, and is discharged into a room through a discharge grill 9 in front of the dehumidifier. The heat exchanger 60 is provided with an evaporator and a condenser, refrigerant is circulated by a compressor 53, and water dehumidified at the condenser (hereafter called as “condensate”) is collected at a water tank 80 under the heat exchanger 60.
FIG. 5 illustrates an enlarged front view of“A” part in FIG. 4;
FIG. 6 illustrates a perspective view of a housing seen in a “B” direction in FIG. 4;
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. A first preferred embodiment of the present invention will be explained with reference to FIGS. 2˜6.
The barrier part 11 includes a main wall part 12 provided vertical between the compressor 2 and the water tank 6, and sidewall parts 13 extended from both sides of the main wall part 12 to both sides of the drain part 40. The barrier part 11 supports the heat exchanger 3 and the motor 5, and isolates front and rear spaces of the shroud part 20. There are a plurality of reinforcing ribs 12a for reinforcing a supporting strength against the shroud part 20. The main wall part 12 has a space securing recess 14 recessed from a front face(where the compressor is disposed) to a rear face(where the water tank is disposed) for easy mounting of devices, such as the compressor 2 and other tubes. And, as shown in FIG. 6, the main wall part 12 has a plurality of fastening projections 16 on a bottom face thereof for coupling with the base pan 7. Of course, as shown in FIG. 2, the base pan 7 has recesses 7 a for inserting the fastening projections 16. Of the fastening projections 16, the fastening projections on both sides thereof are bent in ‘λ’ forms for inserting into the recesses 7 a in the base pan 7. And, the main wall part 12 has holes 17 and 18 for fitting a switch to make confirmation of water tank 6 mounting and a switch to make confirmation of full of the water tank 6. In the meantime, as shown in FIG. 4, the main wall part 12 has hanging projections 19 on inside surfaces of the sidewall parts 13, and the water tank 6 has recesses 6 a in both sides thereof to insert the hanging projections 19 thereto. And, as shown in FIG. 3, the sidewall part 13 has a cable guide part 19 a.
The shroud part 20 includes an annular shroud 22 projected from a circumference of the air flow hole 20 a in the isolation wall 21. And, there is a tube pass through hole 23 in a side portion of the isolation wall 21 for pass of refrigerant tubes connected from the compressor to the heat exchanger. And, there is a controller fitting part 24 in an upper portion of the tube pass through hole 23 for fitting a controller 9 b connected to an operation switch 9 a fitted to top of the discharge grill 9. The controller fitting part 24 has a hanging part 24 a formed relatively high portion for hanging a controller 9 b, and a projection 24 b formed in a lower portion of the hanging part 24 a for supporting the controller 9 b to prevent movement of the controller 9 b. And, the shroud 22 has a cable guide projection 25 on a front surface thereof for guiding the cable connected to the controller 9 b.
The motor fixing part 30 includes a motor fastener 31 formed in a ring form in front of the shroud part 20 for fastening the motor 5 thereto, and supporting members 35 connected from the motor fastener 31 to the shroud 22 of the shroud part 20 in a radial form. There are a plurality of ribs 32 projected from an inside circumference of the motor fastener 31, for maintaining a gap between the motor 5 and the motor fastener 31, to prevent a heat generated during operation of the motor 5 from transmission toward the motor fastener 31, which is formed by injection molding, as it is, and secure a heat dissipation space of the motor. The supporting member 35 has main supporting members 36 formed at 120° intervals from the motor fastener 31 to the shroud part, and a plurality of supplementary supporting members 37 formed between the main supporting members 36 for maintaining a concentricity of the motor fastener 31 and reinforcing a supporting strength. The main supporting members 36 are formed to have an adequate rigidity for supporting the fan 4 and the motor 4, and the supplementary supporting members 37 are formed to be parallel to a flow direction of the air so as to have the least contact area with a flowing air for minimizing a resistance to the air discharged from the fan 4. The motor fixing part 30 has a plurality of screw holes 33 for fastening the motor 5 with bolts or screws. In this instance, as shown in FIGS. 4 and 5, the screw hole 33 has a nut recess 34 of a regular bolt head form, to cope with a case when the screw hole 33 is worn down owing to frequent screwing for taking out and repair of the motor, when a bolt or nut is inserted in the nut recess 34 and fasten it. According to the present invention, because the motor 5 is firmly mounted on the motor fixing part 30 by the plurality of supporting members 35, and the fan 4 is supported by the firmly mounted motor 5, the vibration generated during operation of the fan 4 and motor 5 can be reduced.
