Description

  The present invention relates to all types of washing machines such as a drum-type washing machine, a fully automatic washing machine, and a two-tank washing machine.

  Conventionally, as shown in FIG. 8, a drum-type washing machine is arranged in an outer box 801 having an opening 801a for loading laundry, and is disposed in the outer box 801 and faces the opening 801a for loading laundry. Some have a water tank 802 having an opening 802a and a rotating drum 803 that is rotatably disposed in the water tank 802 and stores laundry.

  The opening 801a for putting the laundry in the outer box 801 is connected to the opening 802a of the water tank 802 by a door packing 805, and is sealed by the door 806.

  The water tank 802 is suspended in the outer box 801 by an elastic spring 811. A water supply valve 809 and a water supply device 810 are provided above the water tank 802. On the other hand, a drainage device 807 is provided below the water tank 802.

  The rotary drum 803 is directly rotated by a drive mechanism 808 attached to the rear part of the water tank 802. A plurality of small holes 803 a are provided in the entire peripheral wall of the rotating drum 803.

  The top plate 820 at the top of the outer box 801 is fixed to the side of the outer box 801 with screws. By removing the top plate 820, as shown in FIG. 9, the water tank 802, the water supply valve 809, the water supply device 810, and the like are exposed, so that the repair can be performed without moving the outer box 801.

  According to the drum type washing machine having the above configuration, when the laundry is put into the rotating drum 803 and then the start button at the upper front of the outer box 801 is pressed, the water supply valve 809 is opened, and the water supply valve 809 moves to the water tank 802. Water flows towards you. The water passes through the water supply device 810 and flows into the water tank 802 as washing water including the detergent stored in the water supply device 810. When the amount of water in the water tank 802 reaches a predetermined amount, the water supply valve 809 is closed and the rotating drum 803 rotates at a low speed. As the rotating drum 803 rotates, the laundry in the rotating drum 803 is repeatedly lifted and dropped. As a result, the laundry in the rotating drum 803 is soiled by the impact force of dropping.

  When the washing of the laundry is completed, the drainage device 807 is driven, the dirty detergent solution in the water tank 802 is discharged, and the laundry is rinsed.

  When the rinsing is completed, the drainage device 807 is driven again, the rinsing water in the water tank 802 is discharged, and the laundry is dehydrated. In this dehydration, the laundry and the water contained in the laundry are separated by centrifugal force by rotating the rotary drum 803 at a high speed. At this time, the moisture separated from the laundry flows out of the drum 803 from the small hole 803b, then moves downward through the inner wall of the water tank 2, and is discharged out of the washing machine through the drainage device 807. .

  In the drum type washing machine, since the top plate 820 has a flat plate shape, a detergent 851 or the like can be placed on the top plate 820 as shown in FIG. That is, the space on the top plate 820 can be effectively used as a space for placing objects.

  For example, Patent Document 1 (Japanese Patent Laid-Open No. 10-263266) discloses an improved detachability of the top plate 820 of the drum type washing machine as described above. In Patent Document 1, it is possible to perform maintenance and replacement of parts in the outer box by removing the top plate. However, since the edges of other metal parts and wiring are also exposed, safety and reliability are ensured. Only the service person can remove the top plate so as not to lower the performance.

As a result, when the consumable parts in the outer box are consumed, a service man is called and the consumable parts are exchanged by the service person, so that there is a problem that the running cost increases.

  Hereinafter, a washing machine of the present invention will be described in detail with reference to embodiments shown in the drawings.

(First embodiment)
FIG. 1 shows a schematic cross-sectional view of the drum type washing machine according to the first embodiment of the present invention.

  The drum-type washing machine includes an outer box 1, a water tank 2 disposed in the outer box 1, a rotary drum 3 rotatably disposed in the water tank 2, and the laundry tank 2. A drainage device 7 provided at the bottom, a motor 8 for rotating the rotary drum 3, and a water supply device 10 disposed above the water tank 4 are provided. This water supply apparatus 10 is an example of a water supply means.

  The upper part of the outer box 1 is made of a top plate 20, the front part of the outer box 1 is made of a front panel 21, and the bottom part of the outer box 1 is made of a bottom base 22. A rear lid 23 is attached to the rear surface of the outer box 1. The front panel 21 is provided with an opening 21a, and the laundry is taken in and out through the opening 21a. The opening 21 a of the front panel 21 is opened and closed by an external door 24 that can slide in the vertical direction with respect to the front panel 21. The external door 24 is accommodated inside the lower portion of the front panel 21. That is, when the opening 21a of the front panel 21 is opened, the external door 24 is positioned as indicated by a two-dot chain line. In addition, an operation panel 12 having operation keys and a display unit is provided on the curved portion on the front side of the outer box 1. A control device 13 for controlling the operation of the drum type washing machine is arranged on the back side (water tank 2 side) of the operation panel 12.

  The water tank 2 is elastically supported by a suspension 11. Further, the water tank 2 has a bottomed cylindrical shape, and is arranged in a horizontal direction with a slight inclination so that the opening 2a faces the opening 21a of the front panel 21. More specifically, the rotational axis of the rotary drum 3 is inclined such that the rear side (the back side of the rotary drum 3) is lowered by, for example, 10 ° to 20 ° with respect to the horizontal direction. Further, the opening 2a of the water tank 2 and the opening 21a of the front panel 21 are spaced apart from each other. A transparent hinge-type lid body 6 is rotatably attached to the water tank 2. When the opening 2 a of the water tank 2 is closed with the lid 6, water does not leak to the outside from the opening 2 a of the water tank 2.

  A plurality of small holes 3 a are provided in the entire peripheral wall of the rotating drum 3. The small holes 3 a are for flowing liquid (washing water or rinse water) between the space between the water tank 2 and the rotating drum 3 and the space in the rotating drum 3. Further, a baffle 3b is provided on the inner wall surface of the rotating drum 3 so as to protrude inward in the radial direction. The baffles 3b are provided at three locations, for example, at 120 ° intervals in the circumferential direction. Such a baffle 3b works to repeat the lifting and dropping of the laundry as the rotating drum 3 rotates. The rotary drum 3 is provided with a fluid balancer 3d that surrounds the opening 3c from the outside. Thereby, when the rotating drum 3 rotates, the imbalance that is caused by the bias of the laundry and the liquid (washing water or rinsing water) is canceled by the movement of the sealed fluid in the fluid balancer 3d.

  The drainage device 7 is opened and closed by a drain valve motor. By opening the drainage device 7, the liquid in the water tank 2 is drained to the outside through a flexible drainage hose 19.

  A nozzle 10 a is provided in the upper part of the water supply apparatus 10. Further, water is supplied from the water supply valve 9 to the water supply device 10. The water from the water supply valve 9 passes through the water supply device 10 and then flows into the water tank 2 through the duct 15.

  FIG. 2 shows a schematic view of the drum-type washing machine as viewed obliquely from above.

  The top plate 20 is formed of resin, and is fixed to the front, side, and rear of the outer box 1 with screws. A concave portion 20 a for accommodating the sheet-shaped canopy 32 is provided at a substantially central portion of the top plate 20. An opening 20 b that faces the silver ion unit 31 is provided near the corner of the bottom surface of the recess 20 a. The canopy 32 is approximately the same size as the recess 20a.

  Since the canopy 32 is merely placed on the bottom surface of the recess 20a, it can be easily removed from the recess 20a. For example, when the silver ion unit 31 is replaced due to a failure or a lifetime, the user can expose the silver ion unit 31 simply by removing the canopy 32 from the recess 20a.

  FIG. 3 is a schematic sectional view of the upper part of the drum type washing machine. In addition, FIG. 3 is based on a different cut surface from FIG.

  The silver ion unit 31 is attachable to and detachable from a water supply path 30 that connects the water supply valve 9 and the nozzle 10a. The water supply path 30 has a substantially inverted T shape, and one end portion of the substantially horizontal portion 30a is connected to the water supply valve 9, and the other end portion of the substantially horizontal portion 30a is connected to the nozzle 10a. The substantially vertical portion 30 b of the water supply path 30 is connected to the silver ion unit 31. When water flows through such a water supply path 30, the water reaches the nozzle 10a after passing through the silver ion unit 31. The substantially vertical portion 30 b of the water supply path 30 and the silver ion unit 31 are watertight with an O-ring 33.

  The water supply device 10 sprays water from the water supply valve 9 into the detergent case 34 using the nozzle 10a. The detergent case 34 can be taken in and out with respect to the water supply apparatus 10, and a detergent and a softening agent can be stored in the detergent case 10d. Moreover, the hole 10b facing the opening part 20b is provided in the upper part by the side of the water supply valve 9 of the said water supply apparatus 10. FIG. Since the substantially vertical portion 30 b of the water supply path 30 is inserted through the hole 10 b, the upper portion of the substantially vertical portion 30 b of the water supply path 30 protrudes from the water supply device 10. A rib 10c is provided so as to surround the hole 10b and the periphery of the silver ion unit 31. The upper end of the rib 10c is fixed to the back surface of the top plate 20, and the inner peripheral surface of the rib 10c and the inner peripheral surface of the opening 10b are substantially flush with each other.

  According to the drum type washing machine having the above-described configuration, the opening 20b faces the silver ion unit 31, so that the silver ion unit 31 is exposed from the opening by removing the canopy 32 from the recess 20a. Therefore, maintenance and replacement of the silver ion unit 31 can be performed without removing the top plate 20. Therefore, for example, the maintenance and replacement of the silver ion unit 31 can be performed by the user himself without relying on a service person, and the running cost can be reduced.

  Further, when the maintenance or replacement of the silver ion unit 31 is performed, the top plate 20 is not removed, so that the edge of the other metal silver ion unit 31 and the wiring are not exposed. Therefore, safety and reliability can be improved.

  Further, since the rib 10c surrounds the silver ion unit 31, the silver ion unit 31 can be maintained and replaced safely.

  Moreover, since the opening part 20b is covered with the canopy 32 by accommodating the canopy 32 in the recessed part of the said top plate 20, design property can be improved.

  Since the canopy 32 is only placed on the bottom surface of the recess 20a, the canopy 32 can be easily cleaned by removing the canopy 32 from the recess 20a.

  Further, since the canopy 32 is merely placed on the bottom surface of the recess 20a, the color and design of the canopy 32 can be easily adjusted to the user's preference by replacing the canopy 32.

  The drum type washing machine operates as follows.

  After the laundry is put into the rotating drum 3, when a start button on the operation panel 12 is pressed, the water supply valve 9 is opened and water flows from the water supply valve 9 toward the water tank 2. The water passes through the water supply device 10 and flows into the water tank 2 as washing water including the detergent stored in the water supply device 10. When the amount of water in the water tank 2 reaches a predetermined amount, the water supply valve 9 is closed and the rotary drum 3 rotates at a low speed. As the rotating drum 3 rotates, the laundry in the rotating drum 3 is repeatedly lifted and dropped. As a result, the laundry in the rotating drum 3 is soiled by the impact force of dropping.

  When the washing of the laundry is completed, the drainage device 7 is driven, the dirty detergent solution in the water tub 2 is discharged, and the laundry is rinsed.

  When the rinsing is completed, the drainage device 7 is driven again, the rinsing water in the water tank 2 is discharged, and the laundry is dehydrated. In this dehydration, the laundry is separated from the moisture contained in the laundry by centrifugal force by rotating the drum 3 at a high speed. At this time, the water separated from the laundry flows out of the drum 3 through the small holes 3b, moves downward through the inner wall of the water tank 2, and is discharged out of the washing machine through the drainage device 7. .

  In short, the drum type washing machine of this embodiment can perform the same operation as the conventional drum type washing machine of FIG.

  Even if the canopy 32 is not provided, the appearance and the like are not affected by the appearance problem, but it is inconvenient when an object is placed on the top plate 20.

(Second Embodiment)
In FIG. 4, the schematic sectional drawing of the upper part of the drum type washing machine of 2nd Embodiment of this invention is shown. 4, the same components as those shown in FIG. 3 are denoted by the same reference numerals as those in FIG. 3, and the description thereof will be omitted or simply described.

  The drum type washing machine of the present embodiment is different from the first embodiment in the configuration of the top plate 120 and the detergent case 134. More specifically, the top plate 120 includes a fixed portion 120A and a slide portion 120B that can slide in the front-rear direction with respect to the fixed portion 120A. The fixing portion 120A is fixed to the front, side and rear portions of the outer box 101 with screws. A concave portion 120 a that houses the plate-shaped canopy 32 is provided at a substantially central portion of the top plate 120. An opening 120b facing the silver ion unit 31 is provided near the corner of the bottom surface of the recess 120a. A part of the peripheral wall of the recess 120a is configured by an end portion of the slide portion 120B on the water supply valve 9 side. The slide part 120B is connected to the detergent case 134. Accordingly, when the slide part 120B is slid forward, the detergent case 134 can be pulled out. Thus, the slide part 120B also serves as a handle for the detergent case 134.

  According to the drum-type washing machine having the above-described configuration, the same effect as that of the first embodiment is obtained, and the side surface of the canopy 32 is exposed by sliding the slide portion 120B forward. Can be turned easily. That is, the user can easily remove the canopy 32 from the recess 120a.

  A protrusion for hooking a hand may be provided on the side surface of the canopy 32. In this case, the user can turn the canopy 32 more easily by hand.

  In the first and second embodiments, the opening 20b facing the silver ion unit 31 is provided on the top plates 20 and 120. However, the opening facing the water purification unit or the like in the outer box 1 or 101 is provided on the ceiling. The plates 20 and 120 may be provided.

  Moreover, in a washing machine with a drying function, you may provide the opening part which opposes the filter provided in the ventilation path in an outer box in a top plate.

  In short, the top plate of the washing machine may be provided with an opening facing a part that requires user maintenance among the parts in the outer box.

  In the first and second embodiments, the canopy 32 may be made of an elastic body such as rubber. When the canopy 32 is made of an elastic body, even if the bottom surfaces of the recesses 20a and 120a are warped, the canopy 32 can be adapted to the bottom surfaces. Therefore, shakiness of the canopy 32 due to warping of the bottom surfaces of the recesses 20a and 120a can be prevented.

  In addition, when the canopy 32 is made of an elastic material, the canopy 32 can be prevented from rattling, so that a detergent or the like placed on the canopy 32 can be prevented from falling due to rattling of the canopy 32. Therefore, the user will not be uncomfortable with the noise caused by the drop of detergent or the like placed on the canopy 32.

  In addition, if the canopy 32 is formed of a transparent or translucent material, the silver ion unit 31 can be confirmed without removing the canopy 32 from the recesses 20a and 120a. it can.

  The canopy 32 may be made of a single material or may be made of a plurality of different materials. For example, a canopy 132 shown in FIG. 5 may be used instead of the canopy 32. The canopy 132 is obtained by bonding or insert molding a front side member 132a and a back side member 132b made of a material different from the front side member 132a. When the material of the front side member 132a is a non-heat resistant material capable of printing or the like, and the material of the back side member 132b is a heat resistant material, the back side member 132b can be conveniently used as an ironing board.

  Further, instead of the canopy 32, for example, a canopy 232 having a substantially concave cross section shown in FIG. 6 may be used. When this canopy 232 is used, even if a wet cloth or liquid detergent is placed on the canopy 232, the liquid can be prevented from entering the outer box 1101. Further, if the canopy 232 is removed from the recesses 20a and 120a, it can be conveniently used as a tray for carrying a wet cloth or liquid detergent.

  In addition, instead of the canopy 32, a canopy 332 shown in FIG. Cylindrical shaft portions 332c are provided on the left and right sides of the end portion of the canopy 332 on the water supply valve 9 side. The shaft portion 332c is held by the top plate 20, and the canopy 332 can be rotated to the position of the two-dot chain line.

  Moreover, since the canopy 332 is connected to the top plate 20, the canopy 332 can be prevented from being lost.

  Further, although not shown, the canopy 332 may be rotatably attached to the top plate 120. Further, like the canopy 332, the canopy 132 may be rotatably attached to the top plate 20 or the top plate 120, or the canopy 232 may be rotatably attached to the top plate 20 or the top plate 120. Good.

  The canopy of the present invention may be made of the same resin as the top plate or may be made of a foam.

  Further, it is preferable to provide a handle on the canopy of the present invention because the operability of the canopy is improved.

  Further, the present invention can be applied not only to a drum type washing machine but also to various washing machines such as a so-called vertical type fully automatic washing machine and a two-tank washing machine.

  The present invention can be applied not only to a washing machine having a drying function but also to a washing machine having no drying function.
