Definitions

  • the present invention relates to drum-type washing machines that wash clothes and others.
  • a conventional drum-type washing machine is disclosed in, e.g. Unexamined Japanese Patent Application Publication No. H10-127978 (Patent Literature 1).
  • This washing machine includes a pump for supplying wash water stored in a water tub into a water circulating path and a nozzle having multiple holes through which the wash water jets from this side of a rotating drum toward an inner part of the drum.
  • the nozzle is placed in front of the drum and the multiple holes are formed at slightly different angles from each other, so that clothes loaded in the drum can get wet fast.
  • the rpm of the drum is controlled to prevent the wet clothes from tangling with non-wet clothes or clustering between the wet clothes.
  • Fig. 18 is a lateral cross section schematically illustrating a method for jetting wash water of the drum-type washing machine.
  • Fig. 19 is a perspective view of nozzle 26 in part.
  • the drum-type washing machine is formed of: housing 1, water tub 2, rotary drum 4, motor 44, pump 21, water shut off valve 6, drain valve 19, water circulating path 20, feed valve 15, vents 13, drain path 18, drain port 17, door 7, motor pulley 40, driving belt 41, driving pulley 42, tank 43, and nozzle 26.
  • the dotted lines in Fig. 18 indicate the jets of wash water.
  • Nozzle 26 shown in Fig. 19 includes inlet 24 through which the wash water to be jetted is supplied, and multiple nozzle holes 31 having openings at different positions.
  • the foregoing conventional drum-type washing machine jets the wash water from the door side toward the inner part of drum 4 through nozzle 26 placed above drum 4 at the door side, thereby wetting the laundry for washing.
  • This method fails to practically wet the laundry when a small volume of laundry is loaded in drum 4 because the water jetted in parts fail to hit the laundry but hit the drum directly.
  • the wash water jetted in parts only hit the laundry near to the nozzles or nozzle holes, so that nozzle 26 also fails to wet the laundry uniformly or in a wider area. In these cases, wash performance for the entire laundry cannot be improved.
  • the nozzle Since the nozzle has multiple nozzle-holes, greater pressure loss is incurred during the water supply from the circulating path to the individual holes. As a result, a smaller amount of wash water is jetted from each one of the nozzle holes, so that it is difficult to wet the clothes quickly and uniformly.
  • a nozzle greater in size is used, and multiple nozzles are provided in the water tub for jetting the wash water over the greater area.
  • these measures cause the laundry rotating in the rotary drum to tangle with the nozzles.
  • GB 2 308 388 A relates to a washing machine having a spraying nozzle assembly.
  • the washing machine has a spraying nozzle assembly which evenly and strongly sprays a circulated washing liquid onto an article to be washed.
  • the washing machine has a housing, an outer tub disposed in the housing so as to receive the washing liquid, a spin tub accommodated in the outer tub, an outer tub cover mounted on the outer tub, and a spraying nozzle assembly for spraying the washing liquid onto the article to be washed which is loaded in the spin tub.
  • the spraying nozzle assembly includes an upper frame mounted on an upper surface of the outer tub cover and a lower frame which is rotatably coupled to a lower portion of the upper frame.
  • the lower frame is formed at a bottom wall thereof with a plurality of spraying nozzles which are regularly arranged in a spiral pattern.
  • the washing machine can evenly and strongly spray the circulated washing liquid onto the articles through the spraying nozzles arranged in the spiral pattern, so the washing effect can be improved without wasting any washing liquid. Since the lower frame rotates while the washing liquid is being sprayed, the washing liquid does not concentrate at one spot of the articles, but sprays widely onto the articles.
  • US 2010/0000266 A1 relates to a washing machine.
  • the washing machine has a water spray device to efficiently wet the laundry by spraying washing water to the laundry with uniform pressure.
  • the washing machine includes an outer tub, and a water spray device installed at an upper portion of the outer tub to spray washing water.
  • the water spray device includes a diffusion duct for diffusing the washing water around the outer tub and a spray member provided in the diffusion duct to spray the washing water into the outer tub.
  • US 2007/0107471 A1 relates to methods and apparatus for washing machine.
  • a spraying device for a washing machine includes a body including a wall having an outer surface, a water inlet and a channel defined therein. The channel is in flow communication with the water inlet, and a plurality of nozzles extend through the wall and in flow communication with the channel.
  • the washing machine includes a wash tub and a basket mounted within the wash tub. The basket is configured to rotate.
  • the nozzles include an inlet, an outlet, an inner diameter, and an outer diameter.
  • At least a portion of the outlet includes a surface substantially perpendicular to a flow of water through the nozzle, and the nozzles have a length longer than a thickness of the wall. At least a portion of the outlet is unitary with the wall outer surface.
  • US 2003/0061843 A1 relates to a drum type washing machine.
  • the drum type washing machine includes a cabinet which defines an outer appearance of the washing machine, a water tub set inside the cabinet to contain wash water therein, a rotary tub having spin drying perforations and rotatably set in the water tub, and a water turbine which is mounted at an open front of the rotary tub and rotates along with the rotary tub to spray the wash water contained in the water tub into the rotary tub.
  • the water turbine includes an external member having an annular shape, and an internal member having an annular shape corresponding to the external member.
  • the internal member is arranged apart from the external member by a predetermined interval.
  • a vane unit is set between the external and the internal members, and raises the wash water contained in the water tub and sprays the wash water into the rotary tub.
  • JP 2007-082784 A relates to a drum type washing machine. The washing water which turns in the water receiving tub accompanying the rotation of the rotary drum is jetted to the rotary drum from the front side of the water receiving tub by the circulating water passage, and the washing water is fed to clothes in the rotary drum to increase the washing effects.
  • the holding arrangement serves to allow the washing tub to be positioned to be inclined at a predetermined angle with regard to a vertical axis.
  • the water circulating arrangement forcibly circulates washing water from a bottom of the washing tub to a top of the washing tub and is extended from the bottom of the washing tub to the top of the washing tub.
  • a drum-type washing machine comprises the following structural elements:
  • the structure discussed above allows the wash water conveyed by the pump into the water tub to jet over a greater area, thereby exposing the laundry agitated in the rotary drum to the wash water more frequently. As a result, the wash water can be supplied all over the laundry in the drum, thereby wetting the laundry uniformly, and improving the performance of wash and rinse.
  • the opening side of the rotary drum of the drum-type washing machine is referred to as a front, a front side, a front section, or a front face, and the opposite side to the opening side is referred to as a rear, a rear side, a rear section or a rear face.
  • Fig. 1 is a sectional view of a drum-type washing machine in accordance with the first embodiment of the present invention.
  • This drum-type washing machine as shown in Fig. 1 , comprises the following elements: housing 1, water tub 2, suspension 3, rotary drum 4, openings 5 and 6, door 7, motor 9, protrusion 12, feed valve 15, drain valve 19, water circulating path 20, pump 21, nozzle water path 22, nozzle 26.
  • the washing machine further comprises controller 32 mounted on a rear bottom in housing 1 for controlling motor 9, feed valve 15, drain valve 19, and pump 21 as well as controlling the steps of wash, rinse, and spin-dry based on a given program.
  • Water tub 2 shaped like a cylinder having a bottom is resiliently supported by suspension 3 in housing 1.
  • Rotary drum 4 shaped like a cylinder having a bottom is placed rotatably in water tub 2.
  • Rotary axis 4a of drum 4 substantially agrees with the center line on which rotary drum 4 rotates, and also substantially agrees with the center line on which water tub 2 rotates.
  • Tub 2 and drum 4 have circular openings 5 and 6 respectively, on the front, i.e. the place where door 7 is mounted.
  • Rotary axis 4a tilts rearward (front-up and rear-down) by, e.g. 1.0 - 20 degrees relative to the horizontal 4b, so that water tub 2 can be situated in housing 1.
  • door 7 is placed on the front of housing 1 for loading or unloading the laundry into or from drum 4.
  • Bellows 8 made of elastic material such as rubber is placed around opening 5 of water tub 2, so that shut of door 7 bites a rim of bellows 8 at inner face of door 7 for sealing door 7 shut.
  • Drain port 17 is formed on the underside of water tub 2 for discharging the wash water stored in tub 2, and drain path 18 is connected to drain port 17 for conveying the wash water to the outside of housing 1. Drain valve 19 is placed somewhere in path 18 for closing path 18.
  • Circulating path 20 connected to drain port 17 branches off from drain path 18 so that the wash water discharged from tub 2 can circulate via rotary drum 4 into water tub 2 again.
  • Circulating path 20 is laid under water tub 2 such that it extends from the rear to the front and lies almost horizontally.
  • Driving pump 21 placed somewhere in circulating path 20 draws the wash water stored in water tub 2 from drain port 17 into path 20, and pressurizes the wash water flowing in path 20 for conveying it into drum 4. This mechanism allows the wash water stored in water tub 2 to run through path 20 and circulate to tub 2.
  • Nozzle water path 22 is formed inside the front face of water tub 2, to be more specific, on the inner face of opening 5 viewed from opening 6 of drum 4 and outside of rim 23a of circular opening 6 of drum 4.
  • Nozzle water path 22 is shaped like a circle, which is approx. concentric (including concentric) with opening 5 of tub 2 and opening 6 of drum 4.
  • Inner rim 23a of path 22 is placed outside rim 23a of opening 6 in the radial direction.
  • FIG. 2 shows a sectional view of an essential part of the drum-type washing machine in accordance with the first embodiment.
  • flow-in port 25 is formed at an upper section of circulating path 20 such that port 25 communicates with path 20.
  • Nozzles 26 are provided at an upper section of nozzle water path 22 which is formed circularly outside rim 23 a of opening 6.
  • Space 27 is provided between nozzle 26 and rim 23 a.
  • Reflector 28 is provided in space 27 for the wash water jetted into space 27 to reflect thereon toward opening 6. The jetted wash water can be thus guided to opening 6 and then into drum 4.
  • Reflector 28 is formed annularly around opening 5 and confronts the front of rotary drum 4.
  • Reflector 28 includes hit-face 28a tilting relative to the jet stream from nozzle 26. This tilt avoids scattering the wash water in all directions and allows the jet stream of wash water to land stably on hit-face 28a, thereby diffusing the wash water along hit-face 28a. As a result, the wash water can be sprayed over the laundry in drum 4 in a stable manner.
  • a smaller tilt angle of hit-face 28a relative to the jet direction from nozzle 26 allows the jet stream to land more stably on hit-face 28a and diffuse over a greater area.
  • reflector 28 is formed of only hit-face 28a, a small tilt angle of hit-face 28a fails to guide the jet stream into the inner part of drum 4, and the wash water is sprayed onto only the clothes located at the front part of drum 4.
  • guide-face 28b is formed on the inner rim of reflector 28, and the tilt angle of reflector 28 relative to the jet direction is set smaller than that of guide-face 28b.
  • This structure allows setting the tilt angle of hit-face 28a gently relative to the jet direction from nozzle 26, whereby the jet stream of the wash water can land at hit-face 28a more steadily and diffuse over a wider area regardless of the direction which guides the jet stream into drum 4.
  • the jet stream is guided by guide-face 28b along the direction toward inside drum 4, so that the wash water can be sprayed over the laundry in drum 4 in a steady diffusing manner.
  • the length of guide-face 28b is set shorter than that of hit-face 28a because it is necessary for hit-face 28a to have a greater contacting area than a hitting area of the jet stream so that the jet stream can stably land on hit-face 28a and diffuse. Since guide-face 28b functions only as changing the jet stream direction, a smaller contacting area of guide-face 28b than that of hit-face 28a works good. This structure allows minimizing the reduction in the flow velocity at guide-face 28b, thereby spraying the wash water more strongly over the laundry. As a result, the performance of wash and rinse can be improved.
  • the jet stream from nozzle 26 should run to reflector 28, so that a water-guide wall, which is regularly used in a conventional washing machine, is omitted from Fig. 2 .
  • Omission of the water-guide wall allows the jet stream from nozzle 26 to flow into space 27, and then hit the hit-face 28a, and diffuse into drum 4 through opening 6 with the aid of guide-face 28b.
  • the mechanism allows nozzle 26 to be located away from the rim of opening 6 of drum 4 while the jet stream from nozzle 26 can be guided into rotary drum 4 free from adverse resistance from the wall. As a result, this structure allows minimizing the reduction in the flow velocity, thereby spraying the wash water more strongly over the laundry in drum 4.
  • Nozzle 26 is not necessarily shaped like a flat tube which is required for running along the water guide wall, but its cross-sectional area should equal to that of the flat one, so that the cross section of nozzle 26 is shaped like, e.g. a round hole because this shape invites the least pressure loss.
  • This shape allows minimizing the reduction in volumetric flow of the wash water jetted from nozzle 26, so that a sufficient quantity of the wash water can be supplied to the laundry in drum 4.
  • Reflector 28 diffuses the bar-shaped jet stream, so that the wash water can be sprayed in a wide area over the laundry in rotary drum 4. As a result, the performance of wash and rinse can be improved.
  • Fig. 3 is a fragmentary view taken along arrows 3 - 3 of the drum-type washing machine shown in Fig. 1 .
  • Fig. 3 shows the structure viewed from opening 6 of rotary drum 4.
  • nozzle water path 22 is provided with flow-in port 25 at the lower a section.
  • Nozzle water path 22 runs along the shape of water tub 2, so that path 22 shapes approx. annularly (including a circle), and it branches off at port 25 to both sides and the two branched paths extend to end parts 22a respectively.
  • the water flowing in path 22 is split into two streams which run long and approx. annularly (including a circle) such that the streams surround opening 5. This split makes each one of the streams short, which reduces the pressure loss in nozzle water path 22.
  • Nozzle water path 22 is not necessarily provided with end parts 22a, so that path 22 can be formed seamlessly. In this case, since the water flow is also split into two directions at flow-in port 25, an advantage similar to what is discussed above is obtainable.
  • the wash water flows into nozzle water path 22 from flow-in port 25 along the direction toward rotary axis 4a (direction indicated by arrow C in Fig. 3 ).
  • This structure allows the streams to branch off smoothly in two directions, thereby applying sufficient pressures onto respective nozzles 26a - 26g. As a result, this structure can increase the velocity of the jet streams.
  • path 22 is preferably structured to avoid this possible problem. For instance, a path running clockwise and another path running counterclockwise are prepared so that the wash water cannot dash against each other at port 25.
  • multiple nozzles 26a - 26g provided in nozzle water path 22 are supposed to jet the wash water toward rotary axis 4a (e.g. nozzle 26c is supposed to jet the wash water along the alternate long and short dash line); however, the jet direction is shifted from the alternate long and short dash line to the arrow line by angle ⁇ 1.
  • Respective nozzles 26a - 26g are thus shifted toward the same direction by the same angle ⁇ 1 (shift angle). This structure allows enlarging the area over which the wash water can be sprayed, so that the wash water can be supplied all over the laundry in an efficient manner.
  • Thickness "L” of nozzle hole 31 is set not greater than diameter "d” thereof, because if the length of hole 31 along the jet direction is too long, the contracted flow separated from the inside wall of hole 31 flares gradually before the flow is jetted, which cancels the advantage of increasing the velocity of flow. This is the reason why thickness "L” of nozzle hole 31 is preferably set not greater than diameter "d” thereof.
  • jet directions "a" (indicated in a solid line with arrow in Fig. 3 ) of respective nozzles 26a - 26g are shifted by angle ⁇ 1 from the directions (indicated in an alternate long and short dash line in Fig. 3 ) directed to rotary axis 4a.
  • This structure allows jetting the wash water uniformly in a wider area, so that the laundry agitated in drum 4 is more frequently exposed to the wash water. As a result, the wash water can be sprayed all over the laundry, and the performance of wash and rinse can be improved.
  • the flow around inner wall 22b of nozzle water path 22 tries to flow as close as possible to inner wall 22b due to the viscosity; however, the tapered hole 31 bends sharply inner wall 22b by well over 90 degrees at the place where the wash water is jetted from hole 31.
  • the flow of wash water thus separates at a greater distance than the conventional one from the inside wall of hole 31, so that the flow is contracted.
  • the structure discussed above thus contracts the jet stream of wash water for increasing the velocity thereof. As a result, stronger jet streams can be expected, and the performance of wash and rinse can be improved.
  • flow-in port 25 formed at an upper section of drum 4 invites no loss in the flow velocity, where the loss is caused by the conversion into potential energy, so that there is no need to vary the jetting area for both of nozzles 26a and 26b.
