Description

  The present invention relates to a drainage hose configuration of a drum-type washing machine, and relates to a configuration for switching the drainage hose to a plurality of directions of the main body, in particular, to the left and right of a main body that is frequently used, and holding the drainage hose.

  Conventionally, the drainage hose of this type of drum-type washing machine performs the mounting work to change the position of the hose stopper having a self-hinge holding the drainage hose left and right when changing the drainage direction from the bottom of the product. (For example, see Patent Document 1).

  In addition, there is an example in which a drainage hose having a bellows configuration is bent and held in an L shape, and the work is simplified using a holder that rotates the drainage hose in the extending direction (see, for example, Patent Document 2).

  FIG. 5 is a longitudinal sectional view of a main part of a conventional washing machine described in Patent Document 1. As shown in FIG.

  As shown in FIG. 5, the drainage hose 23 having one end 23a connected to the bottom (not shown) of the washing tub in the outer box 12 is opened and closed by a self hinge of a hose stopper 24 attached to the lower part of the back plate 12a. One end side is sandwiched by the portion 25, and the other end side is sandwiched by a sandwiching portion 27 that opens and closes by a self hinge of a hose stopper 26 that is detachably attached to the attachment holes 46 at the lower portions of the left and right side plates 12b. For example, in FIG. 5, it is attached to the right mounting hole 46.

  To change the extending direction, first, the outer box 12 is laid down, and the drain hose 23 is removed from the bottom portions of the hose stopper 24 and the holding portions 25 and 27 of the hose stopper 26 by opening and closing the self hinge. 46 is passed through and pulled into the outer box 12.

  Thereafter, the tip of the drainage hose 23 is pulled out from the left side mounting hole 46 to the left side, and the hose stopper 26 is also replaced with the mounting hole 46 below the left side plate 12b and moved to the left side. The drain hose 23 is sandwiched between the stoppers 26.

  FIG. 6 is a diagram showing a conventional drainage hose direction change state described in Patent Document 2. As shown in FIG.

  As shown in FIG. 6, one end of the bellows-like hose body 1 is connected and fixed to the drain valve 34, and the first bellows part 4 is bent and accommodated in the bending holder 10 in an approximately L shape. Then, the connection port 7 at the tip is fixed to the main body (not shown).

  The extension direction is changed by tilting the product, removing the connection port 7 inward (left side in the figure) from the bottom, and looking at the extension direction of the drain valve 34 from the B direction in FIG. When the holder 10 is rotated 180 degrees clockwise (right direction), the first bellows portion 4 expands and contracts in response to bending in the clockwise direction (right direction) in the curved housing portion of the hose body 1, and the hose body 1, the second annular sliding contact portion 5 extends in the clockwise direction (right direction) with respect to the annular sliding portion of the holder 10 with the extending direction of the hose body 1 as the central axis. The outgoing direction is changed.

  Therefore, the extending direction of the hose body 1 can be changed by a simple operation of removing the connection port 7 inward and rotating the holder 10 without removing the hose body 1 from the drain valve 34.

  However, in the conventional configuration of Patent Document 1, the drainage hose 23 is held using another member called a hose stopper 24, the outer box 12 is laid down, and the position of the hose stopper 24 is changed from the bottom. If the washing machine is light in weight, there is little trouble in the work, but because the product weight is large like a drum type washing machine, it is difficult to easily turn the product on its side and change the direction of the drainage hose.

  In addition, since separate members such as the hose stopper 24 and the hose stopper 26 are used, it is necessary to hold the drainage hose 23 once inward and then to hold it again. When the position is shifted, the reliability of the drainage hose is affected.

  Moreover, in the conventional structure of the said patent document 2, it is the structure which changes an extending direction by rotation of the holder 10, there is no operation | work of drawing out the drainage hose etc. of the said patent document 1, and some problems are eliminated. However, since the work is carried out such that the product is laid down and the holder 10 is rotated 180 degrees from the bottom surface, there remains a problem that the work at the time of installing the drum-type washing machine having the product weight is difficult.

  In addition, the drainage hose of Patent Document 1 is a pipe that is connected to a hose stop or connection port of a main body from a member with vibration such as a water tank, and discharges washing water to the outside of the machine. In the case where the dimensions for vibration absorption are changed by changing the direction of drainage, there is a problem that the reliability of the drainage hose is adversely affected.

  Also, in the case of Patent Document 2, the drainage valve 34 connected to the drainage hose is configured at the bottom of the water tank, and is a pipe from a member with vibration similar to that of Patent Document 1, and the same concern is expected. There was a problem.

  Furthermore, the holding of the drainage hose is performed by a member called a hose stopper and a hose stopper which are separate members in Patent Document 1, and by a separate member called a holder in Patent Literature 2, and there is a problem in terms of the number of parts. there were.

  This invention solves the said conventional subject, and it aims at changing the extension direction of a drainage hose and holding it easily and reliably.

  In order to solve the above-mentioned conventional problems, the drum type washing machine of the present invention is arranged to be freely openable and closable at the main body of the drum type washing machine configured to be placed on the lower base plate and the front lower part of the main body. A front cover, a water tank that is supported in a vibration-proof manner inside the main body, a rotating drum that puts clothes rotatably supported in the water tank, and a water tank discharge connected to a drain tube at the bottom of the water tank A hose, a drain valve for controlling drainage from the water tank discharge hose, and a drain port provided in both the left and right sides of the main body by piping in a groove formed by left and right vertical walls formed on the lower base plate from the drain valve A drainage hose connected to any one of the above, the groove is positioned at the approximate center of the main body at substantially the same distance from the outlets provided on both the left and right sides of the main body, and is formed in a beam shape on the left and right vertical wall portions The drainage hose A bent portion that is arranged in the groove portion toward the front-rear direction of the main body and is restricted by the restriction beam portion at a substantially center and bendable on the downstream side of the groove portion, and moves inward of the main body from the discharge port. It is possible.

  This makes it possible to change the direction of drainage from the front of the product body in an upright state in which a heavy product such as a drum-type washing machine is installed without having to lay it down. The drainage hose is held by the groove part and the restriction beam part formed on the lower base plate, so it is difficult for work to occur when the drainage direction is changed, and there is a risk of contact with the tank discharge hose etc. The reliability of the drainage structure can be increased.

  The drum type washing machine of the present invention can easily and reliably change and maintain the drainage extending direction.

It is possible to change the extending direction of the stable drainage hose.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited by this embodiment.

(Embodiment 1)
FIG. 1 is an external view of a drum type washing machine according to an embodiment of the present invention, and FIG. 2 is a partial external view of the washing machine with a front panel removed. 3 is a partial cross-sectional view of the washing machine, and FIG. 4 is a partial plan view of the lower base plate portion of the washing machine.

  In the external view of FIG. 1, a drum-type washing machine main body 51 has a structure in which an openable / closable door body 53 is disposed at the center of a front plate 52 and is placed on a lower base plate 54. A front opening cover 55 is configured between the front plate 52 and the lower base plate 54 so as to be openable and closable in front of the main body 51, and a right discharge port 56 and the right side are provided on the right side of the lower base plate 54. An external drainage connection hose 57 connected to the discharge port 56 is connected.

  A left discharge port 58 is formed on the left side surface of the lower base plate 54.

  2 shows a state in which the front cover 55 is opened. In this state, a front opening 61 is formed below the front plate 52, and the internal drain valve 59, the drain valve 59, etc. The drainage hose 60 and the like to be piped are visually recognized from the front opening 61, and the extension work of the drainage hose 60 can be changed from the front plate 52 side of the main body.

  In FIG. 2, the drain hose 60 shows a state of right drainage in which a drain valve 59 and a right discharge port 56 are internally piped.

  In the partial cross-sectional view of FIG. 3, a water tank 63 that rotatably supports a rotating drum 62 that opens a door 53 and puts laundry clothes is provided inside a main body 51 of the drum-type washing machine. It is supported by a damping damper 66 or the like so as to swing freely.

  A drain tube 64 is formed at the bottom of the water tank 63. The drain tube 64 is made of a material such as rubber and is connected to one end of a flexible water tank discharge hose 65. The other end of the water tank discharge hose 65 is The drain valve 59 and the foreign matter removal filter 68 configured on the lower base plate 54 are connected.

  The drain valve 59 opens and closes the drain for washing water in the water tank 63, and the foreign matter removal filter 68 functions to remove foreign matters contained in the waste water during the drain operation.

  The drain hose 60 is connected to the downstream side from the drain valve 59 and the foreign matter removing filter 68 with the water tank discharge hose 65 side being the upstream side of the washing water flow, and the right side discharge port 56 part of the lower base plate 54 on the downstream side. To be piped.

  The drain hose 60 is made of a flexible material formed in a bellows shape, for example, a resin material such as rubber-containing polyethylene or polypropylene, and can be bent.

  When draining the washing water inside the aquarium 63, the drain valve 59 is opened to allow the washing water inside the aquarium 63 to pass through the drain valve 59 and the foreign matter removal filter 68 from the upstream aquarium drain hose 65. Via, it is discharged from the drain outlet hose 60 on the downstream side through the right outlet 56.

  During the dehydration operation, swinging due to strong vibration of the water tank 63 is absorbed by the flexible water tank discharge hose 65 that can be followed by clothes distributed in an unbalanced manner in the rotating drum 62, and the drain valve 59 and foreign matter removal are performed. The filter 68 and the downstream drainage hose 60 are configured so that vibration does not directly affect them.

  In addition, the lower base plate is provided with a regulating beam portion 76 that regulates the upward movement so that the drainage hose 60 generates a slack and moves upward and does not come into contact with the swinging water tank discharge hose 65 according to the movement of the water tank 63. 54 is formed integrally (details will be described later with reference to FIG. 4).

  Further, in order to stabilize the downstream dimension of the drainage hose for changing the extending direction, the hose holding projections 77a and 77b are positioned (details are described in FIG. 4).

  In the partial plan view of the lower base plate portion of FIG. 4, the drainage hose 60 is in the plane direction of the drum type washing machine at the first arc bent portion 70 from the connection portion 69 between the drainage valve 59 and the foreign matter removal filter 68. A second arc bent portion 72 is formed so as to be connected to a substantially straight portion 71 formed along the AA line as a center line, and further bent to the right in the figure from the center line AA. It connects with the hose base 73 with which the right side discharge port 56 of a right side surface is mounted | worn.

  The drain hose 60 and the hose base 73 are integrally formed as a unit member (for example, by bonding or fitting).

  The straight portion 71 of the drain hose 60 passes through the central groove portion 74 formed by the left and right vertical wall portions 75 a and 75 b integrally formed with the lower base plate 54, and the left and right vertical walls are disposed on the upper surface of the drain hose 60. By integrally forming the restriction beam portion 76 in a beam shape on the portions 75a and 75b, the linear portion 71 of the drainage hose 60 is configured not to be disengaged above the central groove portion 74.

  Further, on the upstream side (drainage valve 59 side) from the left and right vertical wall portions 75a and 75b, hose restraining projections 77a and 77b are integrally formed from the left and right, respectively, and the tips of the hose restraining projections 77a and 77b are formed. The gap portion 78 is formed to have a size slightly smaller than the outer diameter of the drainage hose 60.

  Accordingly, the lower base of the drainage hose 60 is positioned between the bottom surface of the central groove portion 74 by positioning by slightly pushing the width of the diameter using the flexibility of the material of the drainage hose 60 and pushing from above the gap portion 78. Since it can hold | maintain in the centerline AA part of the board | plate 54, the length dimension after the 2nd circular arc bending part 72 downstream from the said clearance gap part 78 can be set correctly.

  A hose base 73 integrally connected to the distal end of the drain hose 60 from the second circular arc bent portion 72 is attached to the inner surface side of the right discharge port 56 portion of the right side surface 80 of the lower base plate 54 and discharged. The cylinder 81 is directed outward and the external drainage connection hose 57 is connected.

  The hose base 73 is fixed to the vicinity of the right discharge port 56 on the right side surface 80 of the lower base plate 54 with a small screw 79 from the right outside of the main body.

  Therefore, when the machine screw 79 is loosened from the outside, the hose base 73 can be removed inward of the product.

  FIG. 4 shows a state in which the drainage extending direction is set to the right side. However, when the drainage extension direction is set to the left side, as described in FIG. Open to the front (downward in FIG. 4), loosen the small screw 79 from the right outside of the main body, remove the hose base 73, and draw the drain hose 60 and the hose base 73 to the left from the front of the main body. The second arc bent portion 72 is bent 180 degrees to the left by using the property, and the third arc bent portion 82 shown by the dotted line in the figure is formed, and the hose base 73 is connected to the left discharge port 83. The mounting of the drainage is completed by fixing the hose base 73 in the vicinity of the left outlet 83 with a small screw 79 from the left outside of the main body.

  The operation of the drum type washing machine configured as described above will be described below.

  First, the main body of the drum-type washing machine placed on the lower base plate is configured such that the front cover body is freely opened and closed at the front lower portion thereof, and the work such as internal piping is performed from the front of the product.

  In addition, the drainage hose with a structure that changes the direction of drainage to the left and right is separated from the shaking of the vibrating tank, so it is not directly affected by the vibration of the tank during operation of the drum type washing machine. . Therefore, it is a member that does not cause vibration even if there is a work variation, and there is no risk of greatly affecting reliability.

  In addition, the drain hose is held and positioned by the central groove part formed integrally with the center line part of the lower base plate and the hose restraining protrusions from the left and right sides, so the length after the second circular arc bent part on the downstream side The dimensions are set correctly, and the upward detachment from the central groove is prevented by a position restricting beam configured in a beam shape on the upper surface of the central groove. Therefore, the operation of switching the extending direction to the left and right is stabilized.

  Also, the hose base, which is the most downstream side of the drainage hose, is attached from the inside of the product to the outlet of the lower base plate, and is fixed by fastening a small screw from the outside. The hose base can be easily attached and detached simply by loosening and fastening the small screw.

  As described above, in the present embodiment, since the drainage hose is positioned and held securely, it is possible to prevent contact with other members due to work variations associated with left and right changes in the drainage direction. It increases the reliability of the drainage structure.

  In addition, it is possible to change the direction of drainage from the front of the product body in an upright state where a heavy product such as a drum-type washing machine is installed without performing work such as lying down, reducing work time and workability. It is excellent.

  As described above, the drum-type washing machine according to the present invention can change the extending direction of drainage from the front of the product body in an upright state in which a heavy product is installed without performing work such as lying down. Therefore, it can be applied to uses such as a washing dryer.
