Abstract

A blower for a dehumidifier has a casing, a cover, a small low-voltage motor and a fan. The fan is mounted between the casing and the small low-voltage motor. The cover is mounted on the small low-voltage motor and the fan. The fan draws air in axially from the casing and exhausts air out radially from the cover. Since the small low-voltage motor is directly attached to the cover, the blower has simplified structure. Furthermore, because the fan is mounted between the small low-voltage motor and the casing, the airflow does not pass through the small low-voltage motor. Therefore, dust does not collect on the small low-voltage motor.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a blower, especially to a blower for a dehumidifier.
  • 2. Description of the Prior Arts
  • A dehumidifier draws moist air to pass through a heat exchanger by a blower. The heat exchanger condenses moisture from the moist air so that the moist air is transformed into dry air. Then the dry air is exhausted out by the blower to reduce humidity of surrounding air.
  • With reference to FIGS. 5 and 6, a conventional blower 90 for dehumidifier comprises a casing 91, a cover 92, a fan 93 and an alternating current (AC) motor 94. A heat exchanger 80 and the cover 92 are mounted respectively on two sides of the casing 91. The casing 91 has multiple ribs 911 for securing the AC motor 94. The fan 93 is a centrifugal fan, is connected electrically to the AC motor 94 and is mounted in the cover 92. When the dehumidifier is operated, the fan 93 axially draws moist air through the heat exchanger 80. Then the dry air is exhausted radially by the fan 93.
  • Since the AC motor 94 is heavier and larger, the ribs 911 of the casing 91 are necessary for stably securing the AC motor 94. Thus, the structure of the casing 91 is complicated. Furthermore, the AC motor 94 is located at the air inlet side of the fan 93 so that the AC motor 94 blocks the airflow and easily collects dust.
  • To overcome the shortcomings, the present invention provides a blower for a dehumidifier to mitigate or obviate the aforementioned problems.
    • SUMMARY OF THE INVENTION
  • The main objective of the present invention is to provide a blower for a dehumidifier with simplified structure and small volume. The blower has a casing, a cover, a small low-voltage motor and a fan. The fan is mounted between the casing and the small low-voltage motor. The cover is mounted on the small low-voltage motor and the fan. The fan draws air in axially from the casing and exhausts air out radially from the cover. Since the small low-voltage motor is directly attached to the cover, the blower has simplified structure. Furthermore, because the fan is mounted between the small low-voltage motor and the casing, the airflow does not pass through the small low-voltage motor. Therefore, dust does not collect on the small low-voltage motor.
  • Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective view of a blower in accordance with the present invention, shown connecting with a heat exchanger.
  • FIG. 2 is an exploded perspective view of the blower in FIG. 1 with the heat exchanger;
  • FIG. 3 is an exploded perspective view of the blower;
  • FIG. 4 is a side view in partial section of the blower in FIG. 1 with the heat exchanger;

  • FIG. 6 is a side view in partial section of the conventional blower in FIG. 5 with the heat exchanger.
    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • With reference to FIGS. 1 and 2, a blower for a dehumidifier in accordance with the present invention comprises a casing 10, a cover 20, a small low-voltage direct current (DC) motor 30 and a fan 40.
  • With further reference to FIG. 3, the casing 10 has an air inlet 11 formed axially therethrough.
  • The cover 20 is attached securely to an outer side of the casing 10 and is covered by the air inlet 11 of the casing 10. A heat exchanger 50 of the dehumidifier is attached to an inner side of the casing 10. The cover 20 has a main wall 21 and a sidewall 22. The main wall 21 has a through hole 211 formed axially therethrough. The sidewall 22 is formed around an annular edge of the main wall 21, is attached securely to the casing 10 and has an air outlet 221 formed transversely therethrough.
  • The small low-voltage DC motor 30 is attached securely to the main wall 21 of the cover 20 and has a motor body 31 and a rotating shaft 32. The motor body 31 is attached securely to the main wall 21 of the cover 20. The rotating shaft 32 extends rotatably out from the motor body 31, is mounted in the cover 20 and protrudes toward the air inlet 11 of the casing 10. In a preferred embodiment, the motor body 31 is mounted through the through hole 211 of the main wall 21 of the cover 20 and has multiple tabs 311. The tabs 311 are formed separately on and protrude transversely out from an annular edge of the motor body 31. Multiple screws 34 are mounted respectively through the tabs 311 and are mounted securely into the main wall 21 of the cover 20.
  • Because the small low-voltage DC motor 30 is light and small, the small low-voltage DC motor 30 is directly attached to the main wall 21 of the cover 20 without additional reinforced structure. Therefore, the volume of the casing 10 is decreased. Furthermore, the small low-voltage DC motor 30 has advantages including high efficiency, energy saving and safety. Moreover, the driving voltage of the small low-voltage DC motor 30 is lower than 24 volts.
  • With further reference to FIG. 4, the fan 40 is mounted securely around the rotating shaft 32, is mounted in the cover 20 and is mounted between the casing 10 and the small low-voltage DC motor 30. The fan 40 draws in air axially from the air inlet 11 of the casing 10 and exhausts air radially out toward the air outlet 221 of the cover 20. In a preferred embodiment, the fan 40 is a centrifugal fan. Since the fan 40 is mounted between the casing 10 and the small low-voltage DC motor 30, the small low-voltage DC motor 30 does not block the airflow so that dust does not collect on the small low-voltage DC motor 30.
  • In a preferred embodiment, the rotating shaft 32 has a main part 321, an extending part 322 and a shoulder 324. The extending part 322 is thinner than the main part 321 and has outer threaded wall. The shoulder 324 is formed between the main part 321 and the extending part 322. At least one protrusion 323 protrudes transversely out from the extending part 322 near the shoulder 324. The fan 40 has a connecting wall 41 mounted around the rotating shaft 32 of the small low-voltage DC motor 30. The connecting wall 41 has a step 413 and a connecting hole 411. The step 413 is formed in an outside surface of the connecting wall 41 and is mounted around the main part 321 of the rotating shaft 32. The connecting hole 411 is formed through the step 413 and is mounted around the extending part 322 of the rotating shaft 32. At least one notch 412 is formed through the step 413, is formed around and communicates with the connecting hole 411 and respectively engages the at least one protrusion 323 of the rotating shaft 32. A fastener 33 is mounted around the extending part 322 of the rotating shaft 32 and is attached to the step 413 and has a threaded hole 331 screwed onto the outer threaded wall of the extending part 322 of the rotating shaft 32.
  • The blower as described has following advantages. Because the small low-voltage motor 30 is directly connected to the cover 20 without adding reinforced structures, the structure of the blower is simplified and the volume of the blower is reduced. Furthermore, since the fan 40 is mounted between the air inlet 11 and the small low-voltage motor 30, the airflow does not pass through the small low-voltage motor 30. Therefore, the small low-voltage motor 30 does not collect dust and does not influence the airflow.
  • Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
