 2. Prior Art Portable home appliances such as portable dishwashers and portable automatic washing machines are provided with retractable hoses for connecting the appli ance to a source of water such as a faucet of a sink and to provide a discharge line for discharging the water used in washing and rinsing. Normally. the water inlet hose and the drain hose are connected to a single connector which is detachably connected to the faucet of the sink and the hoses have a sufficient length to enable connecting the appliance to the faucet. When not in use. the hoses must be stored and are preferably retracted into the appliance through an opening in the outer cabinet of the appliance to drape or hang in a loose loop between the outer cabinet and the tub or washing chamber. In such an arrangement hoses are often extended from or retracted into the cabinet only with at least some difficulty. and problems have oc curred with the hose becoming snagged on various internal parts of the cabinet and on parts of the machine disposed therein. Also. the hose may be damaged by coming in contact with moving parts during operation of the appliance.  
  To overcome these problems various suggestions have been proposed. For example. it has been proposed to store the hose in a special compartment contained in the cabinet which compartment is adjacent either a side wall or a top wall. It has also been suggested to provide various guides for guiding the hose into an area where it will not become snagged on moving parts or projections of the internal structure of the cabinet of the appliance. However. these proposals for handling the hoses or placing them in a stored position in the cabinet require either additional space in the cabinet or the provision of structural members such as guides or partitions which structural members will increase the manufacturing cost for the appliance.  
  In portable appliances particularly portable automatic washers. a portion of the hose which is still rctained in the cabinet during operation of the appliance may be free to move. Due to vibrations created by the operation of the appliance. the hose may move into contact with moving parts of the appliance and may produce undesirable noise by hitting or slapping against a portion of the cabinet. This slapping against the cabinet is known in the art as hose slaps.&#34; While the provision of separate compartments or hose guides will isolate the hose from coming into contact with the moving parts. such compartments or guides do not prevent the occurrence of hose slaps.&#34;  
 SUMMARY OF THE INVENTION The present invention is directed to an apparatus or device for facilitating extending a flexible conduit. such as a hose. from and retracting the hose back into an appliance cabinet. which hose may be part of a fluid passage means for introducing water to and removing water from a washing chamber of the appliance. The apparatus or device facilitates proper handling and storage of the hose and maintains the hose in a plane parallel to a wall of the cabinet as the hose is being oil moved between an extended position and a stored or retracted position and prevents &#34;hose slaps&#34; and contact of the hose with moving parts of the appliance. The apparatus accomplishes this by providing a hose retainer which engages the hose and which is con nected to one end ofa rod which is mounted for pivoting movement in a plane extending parallel to a wall of the cabinet so that during extension and retraction of the hose. the hose moves in a plane which is parallel to the cabinet wall. Preferably. the end of the rod which is pivotally mounted on the cabinet is provided with means to urge the retainer into sliding engagement with the one wall to ensure that on extension or retraction the hose freely moves in a plane positively spaced from projections and moving parts of the appliance.

 DESCRIPTION OF THE PREFERRED EMBODIMENTS The principles of the present invention are particularly useful for providing a hose retracting apparatus or device generally indicated at 8 (FIG. 2) for a portable appliance having a washing chamber. While the hose retracting device or apparatus of the present invention may be used on various appliances having a washing chamber. it is particularly useful in a portable auto matic washing machine generally indicated at 9 and diagrammatically shown in FIG. I.  
  The automatic washing machine 9 has a tub I0 which receives a perforate clothes container or spin basket I I. An agitator I2 is centrally disposed in the spin basket II and mounted for oscillatable movement with respect thereto and for spinning movement with the hasket during the extraction of water from the clothes in the basket. The tub 10, the spin basket II, the agitator l2 and the drive mechanism therefor are enclosed in a cabinet 13.  
  The cabinet I3 is shown as being generally rectangular in form having a front wall [441. a pair of side walls I41). and 14:1. and a back wall He (FIG. 2) which walls are detachably mounted on an upright flange 15 of a base I6 as by screws 17. The screws 17 may be selftapping screws of the conventional form and extend through walls 14b. 141&#39; and l-Id and flange I5 to detachably secure the cabinet 13 to the base I6. The cabinet 13 also includes a top 19 having a hinged lid 20 openable to afford access to the clothes-receiving opening 21 in a tub ring 22 extending about the tub and over a corresponding opening in a spin basket I]. The cabinet I3 has a timing dial 23 connected to a timer 24 and mounted on the front wall 14a of the top of the cabinet beneath the top I9. Suitable wiring 25 connects the timer 24 to a motor 26 and other electrically operated devices of the machine. The timer dial 23 and timer 24 may be in any desired location and are shown in this present location for illustrative purposes only.  
  Supported above the cabinet base 16 on spring and vibration dampener assemblies 27 is a base plate 28 forming a support for the tub l0, basket II and agitator 12 in a conventional manner. The base plate 28 may be suitably supported on any vibrational dampening assembly which will provide support for the base plate 28 from the cabinet base I6 and which will absorb vibrations caused by spinning of the spin basket I l. The base plate 28 also forms a support for the motor 26 and a drive control mechanism or transmission generally indicated by reference 29 which may also include a clutch and control mechanism. as well as a drive mechanism for oscillatably driving the agitator 12 or spinning the spin basket ll while releasing the agitator to spin freely with the spin basket.  
  A pump 30 for removing wash or rinse water from the tub at the termination of a washing or rinsing operation is also supported below the base plate 28 and has an outlet port (not shown) connected to an adapter or coupler 31 by a flexible conduit or drain hose 32 which extends through an opening 33 in the back wall 14L of the cabinet [3. An inlet port (not shown) of the pump communicates with the washing chamber by means of a conduit 42. It should be understood that the motor 26. drive control mechanism 29 and pump 30 can be mounted in any convenient manner between the cabinet base I6 and the base plate 28 and need not neccssarily be closely adjacent the base plate 28 as shown.  
  The cabinet [3 also includes means for mounting a suitable water inlet control device or water inlet valve 34 of a conventional construction which valve supplies the tub H] with water received by a flexible conduit or water inlet hose 35 which extends through the opening 33 to the adapter 31 which in turn is illustrated as connected to a source of water such as the faucet 36 of a sink 37. The adapter 31 is. of course. provided with a drain outlet connecting to drain hose 32. The water inlet valve 34 (FIG. 2) is connected through a hose 38 that extends to a conventional anti-siphon device 39 which is mounted on a flange 40 on the side wall 14b and discharges into an outlet hose 4] which connects into the tub ring 22 to discharge into the tub 10 (FIG. I).  
  As best illustrated in FIG. 2, the retracting device or apparatus indicated at 8 includes a rod mounting means for pivotally mounting one end of the rod adjacent to side wall 14b which means. as illustrated. is a bracket 51; and a hose retainer 52 pivotally connected to the other end of the rod 50. The bracket 5] is mounted to the front wall [411 by screws and has an upper flange 53 which is secured to either the flange 40 of the side wall 1411 or to a gusset attached thereto by suitable means such as threaded fasteners. As illustrated. the bracket 5|. in addition to providing a pivotal mounting means for the rod 50, provides a mounting for the water inlet valve 34.  
  To pivotally mount the rod 50 on the bracket 51 for movement in a plane parallel to the wall 14b. one end of the rod is provided with a pair of bends to produce an offset portion comprising a short leg 55 and a second leg or portion 56 (FIG. 5). As best illustrated in FIG. 5. the portion 56 extends at a slight angle (approximately ID&#34;) with respect to the remaining portion 57 of the rod 50. The bracket 5I has an opening or aperture 58 through which the short leg 55 extends so that the second leg 56 engages an opposite side 51a of the basket 5i to provide the pivotal connection between the rod 50 and bracket 5!. The bracket 51 is. also. provided with stop means illustrated as a tab or projection 59 bent from the bracket. which tab contacts the leg 56 to limit the arc of pivoting movement of the rod 50 in the clockwise direction as illustrated in FIG. 2. Adjacent to the aperture 58 the bracket 51 supports a clip or clamp 60 which grips the drain hose 32 and holds it in an elevated relationship to the pump 30 and serves as a support point in maintaining the planar position of the hose.  
  As best illustrated in FIG. 4, the hose retainer 52 is provided with engagement means for slidably engaging each of the hoses 32 and 35, which engagement means are illustrated as resilient curved fingers 62 and 63 which extend from one side 64 of a body portion 65 and terminate adjacent an opposite surface 66 on the body portion to form gaps therewith indicated at 66a and 66b. The retainer 52 is preferably made of a resilient material such as plastic and each of the fingers 62 and 63 can be spread apart to receive the respective hoses 32 and 35. Each of the fingers 62 and 63 engage their respective hose with the engagement means being in a plane (along line IVIV of FIG. 2) which extends substantially perpendicular to the plane of surface 66 which is in sliding engagement with the inner surface of a flat portion of wall 14b.  
  To pivotally mount the retainer 52 on the end of the rod 50. the second end of the rod 50 is provided with a hook portion 67 which extends through an elongated slot 68 in the body portion 65 of retainer 52 and hooks around rib member 6511. Thus. the retainer 52 can pivot on the hook portion 67 as the rod 50 moves from its extreme retracted position illustrated in FIG. 2 to an extended position shown in broken lines during extension of the hoses 32 and 35. As mentioned hereinabove. the leg portion 56 engages a surface 51a of the bracket 51 and thus causes a bias ofthe rod 50 toward the wall Mb to maintain the flat surface 66 in sliding engagement therewith.  
  As illustrated. the opening 33 receives a housing 70 having an opening through which the hoses 32 and 35 pass. The housing 70 provides a storage recess in the cabinet 13 for the adapter or coupling 31. To prevent twisting or overlapping of the hoses 32 and 35 and binding of the two hoses as a result. a divider or separator 71, which can be a pin extending horizontally across the opening of the housing or a bar molded as an integral part of housing 70. is provided. The divider maintains the water inlet hose 35 above the drain hose 32.  
  Since it is important to prevent any twisting of the hoses 32 and 35 during installation thereof. one or both of the hoses may be provided with indicator means such as a longitudinal stripe so that the assembler can easily determine ifthe hoses have been attached to the appliances [0 without any twisting. For example. if the hoses are properly oriented. i.e. installed. without any residual twist which would cause a tendency in the hoses to curl or twist. virtually all portions of the stripes 75 will be visible and substantially parallel to the edges of the hoses as shown in FIG. 2.  
  The hose retainer 52, the opening in housing 70 and the clamp 60 and valve 34 provide a three point suspension for the hoses 32 and 35 when they are in the retracted position. Due to the natural rigidity of the hoses. the three point suspension causes the hoses to hang or drape in a plane substantially parallel to the side wall 1412 well away from the moving parts of the appliance and from any parts on which it is possible for the hoses to become snagged. As mentioned above. a tab 59 is provided to prevent or limit the extent or amount of movement of the retracting device 8 in the retracting direction. Thus. when the leg 56 engages the tab 59. the retainer 52 is positioned in its extreme retracted position which prevents the hoses 32 and 35 from draping into a lower position which may enable the hoses to snag or engage moving parts of the appliance.  
  As the hoses are extended for connection of the coupling 3] to the faucet 36. the hoses will assume an extended position which is illustrated in broken lines in FIG. 2. If during operation the hose pair is in a partially extended position with a slight draping. the device 8 provides sufficient restraint to prevent hose slaps&#34; from occurring due to vibrations imparted by the appliance. Thus. the device 8 besides guiding the hose during extension and retraction and preventing the hose from becoming entangled or snagged on the internal parts of the appliance also prevents undesirable noise due to hose slaps.  
  While the retracting device has been described for coacting with a pair of hoses which provide a drain passageway and an inlet passageway for the appliance 9. the retainer 52 can be modified to engage a single hose which may contain one or more fluid passageways.  
  Although various minor modifications might be suggested by those versed in the art. it should be understood that we wish to employ within the scope of the patent warranted hereon all such modifications as reasonably and properly come within the scope of our contribution to the art.
