-
FIG. 1 is a perspective view illustrating an outer appearance of a drum washing machine using a holder according to an exemplary embodiment,FIG. 2 is a perspective view illustrating the interior of the drum washing machine illustrated inFIG. 1 in the case where air moves in a circulation hose, andFIG. 3 is a perspective view illustrating the interior of the drum washing machine illustrated inFIG. 1 in the case where wash water moves in the circulation hose. - As illustrated in
FIGS. 1 to 3 , the drum washing machine 10 includes a cabinet 30 defining an outer appearance of the washing machine 10, a tub 40 placed in the cabinet 30, a drum 50 rotatably placed in the tub 40, and a motor (not shown) to drive the drum 50. - The cabinet 30 has an opening (not shown) perforated in a front surface thereof such that laundry is put into the drum 50 through the opening. A door 20 is coupled to the front surface of the cabinet 30 to open or close the opening (not shown).
- The tub 40 has a plurality of fastening bosses 45 protruding from a front surface thereof. These fastening bosses 45 are used for fastening with a pressure member (500 or 600, see
FIGS. 9 to 11 ). - A circulation pump 70 is arranged beneath the tub 40.
- The circulation pump 70 serves to pump wash water directed from a water supply hose 80 connected to the tub 40, to return the wash water into the tub 40 through a connection hose 90 (see
FIG. 2 ) or through a circulation hose 60 (seeFIG. 3 ). - The circulation hose 60 illustrated in
FIG. 2 serves to provide the wash water to be returned into the tub 40 through the connection hose 90 with air. One end of the circulation hose 60 is connected to a connection pipe 75 and the other end of the circulation hose 60 is connected to the tub 40. - Air present in the tub 40 moves to a lower end of the tub 40 through the circulation hose 60 to thereby be introduced into the connection pipe 75. Then, the air introduced into the connection pipe 75 is mixed with the wash water moving in the connection hose 90, thereby being introduced into the tub 40.
- As the mixture of wash water and air is introduced into the tub 40, bubbles are generated within the drum 50, enhancing the washing ability of the drum washing machine 1.
- The circulation hose 60 illustrated in
FIG. 3 is directly connected to the pump 70 and serves to supply wash water into the tub 40. - Once wash water is introduced into the pump 70 through the water supply hose 80 connected to the tub 40, the wash water is again injected into the tub 40 through the circulation hose 60 via pumping of the pump 70. Although
FIG. 3 illustrates a diaphragm 25 as having an injection hole by way of example, the injection hole may be formed in the tub 40. - The above described circulation of wash water may allow detergent to be uniformly distributed in the wash water, thus enhancing the washing ability of the drum washing machine 1 and reducing the amount of wash water used during washing.
- The above described circulation hose 60 is fixed to a position of the tub 40 by use of a holder 100, 200, 300 or 400, so as to be kept stationary without movement during rotation of the drum 50.
- In addition, the above described circulation hose 60 is made of synthetic rubber, polyurethane, etc., and thus, may be deformed to have various shapes.

FIG. 9 is a perspective view illustrating the interior of the drum washing machine, in a state in which the pressure member is coupled to the tub to which the holder has been mounted, andFIG. 10 is a sectional view taken along the line I-I ofFIG. 9 in the case where the holder of the firstly described embodiment is used. - As illustrated in
FIGS. 9 and10 , the pressure member 500 may be coupled to the front surface of the tub 40. - The pressure member 500 is fastened with the fastening bosses 45 protruding from the front surface of the tub 40, thereby being fixed to the tub 40.
- The pressure member 500 includes an accommodation portion 510 and a pressure plane 520 provided at the accommodation portion 510.
- The accommodation portion 510 takes the form of a recess having an open side such that the coupling loop 140 of the hook 180 and a part of or the entire circulation hose 60 fitted to the inner peripheral surface of the coupling loop 140 may be received in the accommodation portion 510.
- The pressure plane 520 comes into contact with a part of the coupling loop 140 and acts to press the hook 180 and the circulation hose 60 toward the front surface or lateral surface of the tub 40.
- In a state in which the holder 100 of the firstly described embodiment is mounted to the tub 40, the pressure member 500 is coupled to the tub 40 to cover the holder 100 and serves to prevent the hook 180 and the circulation hose 60 coupled to the hook 180 from moving forward or rearward due to rotational vibration of the drum 50.
- The pressure member 500 coupled to the tub 40 may also serve as a weight-balance.
- When the drum 50 is rotated upon receiving drive force from the motor (not shown), laundry received in the drum 50 may be concentrated on one side of the drum 50, thus causing eccentric rotation of the drum 50 because the drum 50 is made of a thin metal panel and has a light weight.
- To prevent the eccentric rotation of the drum 50, the weight-balance is coupled to the tub 40 connected with the drum 50, to increase the weight of the drum 50.
- The pressure member 500 according to the embodiment contains a material (e.g., cement) having an appropriate weight and thus, may serve as a weight-balance to be coupled to the tub 40.
-
FIG. 11 is a sectional view taken along the line I-I ofFIG. 9 in the case where the pressure member is used instead of the fixing plate. - As described above, the holder 300 of the thirdly described embodiment includes the at least one fixing protrusion 310, the seating recess 320 in which the circulation hose 60 is seated, and the fixing plate 380.
- As illustrated in
FIG. 11 , when using the pressure member 600, it may be possible to omit the fixing plate 380 and the fixing protrusion 310. - More specifically, in a state in which the circulation hose 60 is seated in the seating recess 320 indented in the front surface of the tub 40, the pressure member 600 is coupled to the tub 40 to fix the circulation hose 60.
- Once the pressure member 600 is coupled to the tub 40, a pressure plane 620 of the pressure member 600 presses the circulation hose 60, causing the circulation hose 60 to come into close contact with the tub 40 and consequently, preventing movement of the circulation hose 60.
- Similarly, the pressure member 600 contains a material (e.g., cement) having an appropriate weight and thus, may serve as a weight-balance to be coupled to the tub 40.
-
FIG. 12 is an enlarged perspective view of the portion 'B' ofFIG. 2 . - As illustrated in
FIG. 12 , the tub 40 is provided at a lateral surface thereof with a protruding rib 700. - The protruding rib 700 protrudes from the lateral surface of the tub 40 by a predetermined length, and includes a supporting plane 710.
- The supporting plane 710 is provided at a surface of the protruding rib 700, and in particular, serves to support a specific region of the circulation hose 60 that is bent rapidly in the course of being connected to the tub 40, thereby allowing the circulation hose 60 to be naturally connected to the tub 40.
- When the circulation hose 60 is naturally connected to the tub 40 owing to the supporting plane 710, this may also assure efficient circulation of air within the circulation hose 60.
- Although the protruding rib 700 may be integrally formed with the tub 40 during injection molding of the tub 40, the protruding rib 700 may be separately prefabricated and be mounted to the tub 40.
- Hereinafter, one of manufacturing processes of the drum washing machine 10, i.e. a process of assembling the tub 40 will be described.
- The tub 40 consists of a front tub 42 and a rear tub 44 (see
FIG. 2 or3 ). The front tub 42 and the rear tub 44 are individually formed by injection molding. - After the circulation hose 60 is coupled to the front tub 42 via the diaphragm 25, a hose-drawer (not shown) and the holder 100, 200, 300 or 400 according to the embodiments of the present invention, the front tub 42 is assembled with the rear tub 44 via screws, to complete the tub 40.
- Alternatively, the circulation hose 60 may be coupled to the front tub 42 via the holder 100, 200, 300 or 400 after the front tub 42 and the rear tub 44 are assembled with each other.
- As described above, when using the holder 100, 200, 300 or 400 according to the embodiments of the present invention, the circulation hose 60 may be directly fixed to the tub 40. Accordingly, a process of coupling the circulation hose 60 to the tub 40 may be included in the process of assembling the tub 40.
- In this way, a separate process of coupling the circulation hose 60 may be unnecessary, resulting in enhanced productivity.
- As is apparent from the above description, according to the embodiments, simplified fixing of a hose may be possible.
- As a result of stably fixing a hose, it may be possible to prevent the hose from colliding with other interior components of a washing machine due to rotational vibration of a drum. This may prevent abrasion of the hose and also, generation of collision noise.
- With provision of a structure for simplified hose fixing, enhanced assembly efficiency and productivity may be accomplished.
- Although a few embodiments have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles of the invention, the scope of which is defined in the claims and their equivalents.
