Abstract
Description
- The present disclosure relates to a washing machine mainly suitable for household use.
- In the past, for a top-loading washing machine, four positions of a tub are supported by hoisting rods, so as to prevent the tub and a drum near a resonance point from generating vibration and rotation (e.g., refer to a patent literature 1).
- The hoisting rods extend from the lower end of the tub to an inclined top; the tub is suspended and supported by a damping spring; and a dead angle between an angular part of a housing which is rectangular when observed from top and the tub is used as an accommodating place.
- Patent Literature 1: Japan specifically disclosed No. 2005-253626 Bulletin
- However, under a condition of applying a structure with the above hoisting rods, since components of forming the hoisting rods are in sliding contact with the tub, a potential problem of impossibility of eliminating abnormal noise exists. In addition, recently, except a design appearance, from perspectives of visualization of a washing state, visual confirmation of a fault part and the like, a requirement of enabling the housing of the washing machine to be transparent so as to see an interior may exist. In order to meet the requirements, the hoisting rods become obstacles and a supporting structure needs to be reconsidered.
- Therefore, as a new supporting structure, it can be contemplated that: the top-loading washing machine is the same as a horizontal washing machine which is called as a front-loading washing machine, and is supported with a damper from the lower side of the tub. In this way, it can be firstly contemplated that: considering propagation of the vibration to the housing, the damper is arranged near the bottom wall of the housing. However, under a condition of applying the structure, compared with the structures of the hoisting rods, the position of the tub is lowered. Therefore, if heights of an operating plate and the like of a cover part of the housing are the same as those of the structures of the hoisting rods, a new problem may be caused, i.e., a distance from the tub/drum to an opening of the cover part of the housing is larger than that of the washing machine which applies the hoisting rods.
- The present disclosure is completed to effectively solve such problem. A purpose of the present disclosure is to provide a washing machine. The washing machine adopts a supporting structure which is so far not present, and vibration in a working process may be well inhibited compared with a structure which applies a hoisting rod.
- The present disclosure is a technical solution completed in view of the above problem.
- That is, the washing machine of the present disclosure includes: a drum for accommodating laundry and formed with a drum side opening; a tub for accommodating the inner drum; and a housing for accommodating the drum and the tub, the washing machine includes: a damper vertically arranged from a bottom wall, absorbing vibration of the tub and supporting a lower end of the tub; and a hopper arranged between the drum side opening and a lid side opening and configured to guide throwing-in and taking-out of laundry from the lid side opening to the drum side opening.
- In addition, in the present disclosure, the hopper is formed with an approximately conical shape, and includes: a lower end part connected with an upper end part of the drum; and a large-diameter upper end part formed with a diameter which gradually increases upwards from the lower end part.
- In addition, in the present disclosure, at least part of the housing and the hopper are provided to be transparent or semitransparent.
- In addition, in the present disclosure, the hopper is made of material with a specific gravity smaller than that of the materials of the tub and the drum.
- In addition, in the present disclosure, the hopper performs a function as a heightened drum for storing water with a water level higher than the upper end of the drum.
- In addition, in the present disclosure, the hopper includes: an extending part extending from an inner circumference of the tub to the drum side opening; and a hopper body integrally arranged vertically from the extending part.
- The present disclosure described above has: the damper vertically arranged from the bottom wall of the housing, absorbing vibration of the tub and supporting the lower end of the tub; and the hopper arranged between the drum side opening and the lid side opening and configured to guide throwing-in and taking-out of the laundry from the lid side opening to the drum side opening. Thus, generation of abnormal noise caused by sliding contact between the hoisting rods and the tub is eliminated by removing the hoisting rod; and the damper is provided for supporting near the bottom wall of the housing, thereby effectively inhibiting an influence of the vibration caused by an overturning moment on the housing. In addition, the hopper is clamped between the housing and the drum; and even if a distance between the drum side opening and the lid side opening is increased, taking-out and throwing-in of the laundry can be properly guided.
- In addition, according to the present disclosure, the hopper is formed with the approximately conical shape, and includes: a lower end part connected with the upper end part of the drum; and the large-diameter upper end part formed with a diameter which gradually increases upwards from the lower end part. In other words, an inverted truncated cone shape or an approximate mortar shape is adopted. Therefore, an opening area of the upper end part of the hopper can be obtained more broadly than the drum, thereby further enhancing convenience of taking-out and throwing-in of the laundry.
- In addition, according to the present disclosure, at least part of the housing and the hopper are provided to be transparent or semitransparent. Therefore, except a design appearance, visualization of a washing state and visual confirmation of a fault part can be enhanced.
- In addition, according to the present disclosure, the hopper is made of the material with a specific gravity smaller than that of the materials of the tub and the drum. Therefore, components supported by the damper have light weight, thereby increasing natural vibration frequency and reducing vibration during general dewatering.
- In addition, according to the present disclosure, the hopper performs a function as the heightened drum for storing the water with a water level higher than the upper end of the drum. Therefore, the same effect as the washing machine with an increased volume of the drum can be obtained.
- In addition, according to the present disclosure, the hopper includes: the extending part extending from the inner circumference of the tub to the drum side opening; and the hopper body integrally arranged vertically from the extending part. Therefore, the strength of the hopper can be effectively enhanced regardless of the used material.

Thefixing lid 24 is fixed to the upper end of thehousing body 20, and themovable lid 25 is movably arranged on thefixing lid 24, enables the upper end of thehousing body 20 to be selectively opened outwards and can form a lid side opening 28 which upwards opens the innerdrum side opening 43 formed in the upper end part of thedrum 4 on thefixing lid 24; adamper 6 vertically arranged from thebottom wall 21, absorbing vibration of thetub 3 and supporting the lower end of thetub 3; and ahopper 7 arranged between the drum side opening 43 and a lid side opening 28 and is configured to guide throwing-in of the laundry from the lid side opening 28 to the drum side opening 43 or taking-out of the laundry from the drum side opening 43 to the cover side opening 28. - Structures of constitutive elements which form the
washing machine 1 are illustrated as follows. Firstly, as shown inFIG. 1 andFIG. 2 , thehousing 2 is formed with a bottomed approximately-cylindrical shape and is separated from thetub 3 accommodated inside by an approximately uniform dimension when observed from top. Thehousing 2 includes: ahousing body 20 using acylindrical body 22 which is cylindrical and open at an upper end as a main body; abottom wall 21 arranged on thehousing body 20, i.e., a lower end of thecylindrical body 22 and supporting thetub 3 from the lower side; afixing lid 24 fixed to the upper end of thehousing body 20 and has a circular annular shape when observed from top; and amovable lid 25 has an approximately circular shape when observed from top, movably arranged on thefixing lid 24, enables the upper end of thehousing body 20 to be selectively opened outwards and forming a lid side opening 28 which upwards opens thedrum side opening 43 formed in the upper end part of thedrum 4. - The
housing body 20 includes: acylindrical body 22 with a cylindrical shape, for example, formed by transparent or semitransparent resin of acrylic acid and the like; awire cover 23 arranged across the top and bottom of thecylindrical body 22 and configured to accommodate various wires; and abottom wall 21 indirectly supporting theouter drum 3 from the lower side at a bottom surface side of thehousing body 20. Thefixing lid 24 has a lid side opening 28 with an approximately circular-shaped opening in a circumferential side, and has ahinging part 26 movably supporting themovable lid 25 in a manner of opening and closing. Moreover, awater supply part 27 is arranged. Thewater supply part 27 is disposed in a position for displacing from the hingingpart 26 to a circumferential direction and is configured to supply water to thedrum 4. - The
tub 3 is a bottomed cylindrical component configured in thehousing 2, and can store washing water inside. Thetub 3 has: atub body 31 for storing water; atub cover 32 arranged on an upper end of thetub body 31; and a packing water-sealingpart 34 clamped between thetub body 31 and thetub cover 32 and configured to prevent the water from leaking outwards. The packing water-sealingpart 34 includes: a water-sealingcomponent 36 arranged on the lower side of thetub cover 32; and apacking component 35 configured to prevent the water from leaking. In addition, nearby specific structures about the packing water-sealingpart 34 are described later. - The
drum 4 is a bottomed cylindrical component configured coaxially with thetub 3 in thetub 3 and supported in a manner of free rotation. Thedrum 4 can generally accommodate laundry inside, and has a plurality of water through holes in a wall surface. As shown inFIG. 3 , abalancer 41 protruding inwards in a circular annular shape and threebaffles 42 protruding inwards on a lower side of thebalancer 41 are arranged on an upper end side of an inner circumferential surface of thedrum 4. Then, in a top-loading fullautomatic washing machine 1 in the present embodiment, a pulsator (agitating wing) 5 driven by a drivingdevice 50 shown by an imaginary line is configured in a manner of free rotation in a bottom center of thedrum 4. - The
pulsator 5 generally includes: an approximately disk-shaped pulsator body and a plurality of blade parts formed on an upper surface of the pulsator body. Thepulsator 5 agitates the washing water stored in thetub 3 to produce a water flow. With respect to the drivingdevice 50, although the position of the drivingdevice 50 is shown only by the imaginary line in the same figure, a motor not shown is used as a main body so that a driving shaft extending to a bottom of thedrum 4 rotates to rotate thedrum 4 and thepulsator 5. Thewashing machine 1 mainly rotates thepulsator 5 in a washing process and rotates thedrum 4 and thepulsator 5 integrally at high speed in a dewatering process. - Then, in the present embodiment, the
tub 3 and thedrum 4 in thehousing 2 are supported on thebottom wall 21 of thehousing 2 by means of thedamper 6 from the lower side. Then, thetub 3 is not supported by a hoisting rod from a side surface or an upper side. That is, the configuration of the hoisting rod is avoided in thewashing machine 1 in the present embodiment, thereby further increasing visual confirmation of the laundry to be observed from the upper side, which will be described in detail subsequently. - The
damper 6 is configured to support thetub 3 in a operating state from a lower side and effectively reduce vibration generated by thetub 3 in the operating state. Thedamper 6 includes: aninner shaft 61 fixed to thebottom wall 21 of thehousing 2; anouter shaft 62 covering an outer side of theinner shaft 61 and fixed to thetub 3 side; and aspring 63 serving as a helical compression spring, arranged between the lower end of theouter shaft 62 and thebottom wall 21 side of thehousing 2 and configured to alleviate the vibration transferred to thehousing 2 through proper extension and contraction with up and down movement or vibration of thetub 3. In addition, abuffer rubber 64 is arranged between theouter shaft 62 and thetub 3 and between theinner shaft 61 and thebottom wall 21. In the present embodiment, as shown inFIG. 2 andFIG. 3 , thedamper 6 is configured at a position with a largest diameter or near the position within a range without protrusion, when observed from top, from the bottom of thetub 3. In addition, in the present embodiment, thespring 63 reduces an elastic constant in such a degree that the spring is not close during dewatering and such a degree that thetub 3 is not inclined during operation. - Then, as mentioned above, in the present embodiment, the
hopper 7 is arranged in such a manner of being clamped from an upper side of thetub 3, i.e., specifically from the lid side opening 28 of the fixinglid 24, to thedrum side opening 43. As shown inFIG. 2 andFIG. 3 , thehopper 7 is arranged between thelid side opening 28 and thedrum side opening 43, performs a function as a water receiving guidance component for guiding throwing-in of the laundry from thelid side opening 28 to thedrum side opening 43 or taking-out of the laundry from thedrum side opening 43 to thelid side opening 28, and is configured to guide throwing-in of the laundry from thelid side opening 28 to thedrum side opening 43 or taking-out of the laundry from thedrum side opening 43 to thelid side opening 28. - The
hopper 7 is formed by an integrally formed product constituted to be transparent or semitransparent resinaceous, and includes: ahopper body 71 formed in an approximately conical shape, i.e., a conical shape; and an extendingpart 72 extending from a lower end part of thehopper body 71 to an outer side. A diameter of an opening part as an inner edge of theprotrusion part 72 is formed into a diameter approximately matching with the opening at thedrum 4 side. In addition, thehopper body 71 includes: a large-diameterupper end part 73 which is open to a greater degree than thedrum side opening 43 at the upper end of thehopper body 71; a retracingend 74 arranged on the large-diameterupper end part 73; and anoverflow hole 75 which is an opening formed in any position of a middle position in an up-down direction of thehopper body 71 for setting upper limit water levels of the washing process and the rinsing process. When resin material is used as the material, the material with a specific gravity smaller than that of the material used in thetub 3 is also used sometimes for thehopper 7; and thus, compared with thetub 3, thehopper 7 has a light structure. - Then, as shown in
FIG. 2 andFIG. 4 , anoverflow pipe 76 is connected to the outer side of theoverflow hole 75. Theoverflow pipe 76 is configured to drain water from theoverflow hole 75 to the outer side of the washing machine in order to prevent the water from being stored at the upper side of theoverflow hole 75. Theoverflow pipe 76 uses a part which has a bent oval section when observed from top as a main body in order to effectively use a space bent into a circumferential shape between thecylindrical housing 2 and thetub 3. In addition, since a mechanism and a structure for discharging the water from theoverflow pipe 76 to the outer side of the washing machine belong to an existing art, the related description is omitted. - In addition, in the present embodiment, especially as shown in
FIG. 4 , the inner circumference of the lid side opening 28 of the fixinglid 24 is configured as a shape and size of integrally opening thedrum side opening 43 approximately upwards, and thedrum side opening 43 arranged in the upper end part of thedrum 4 is approximately integrally configured as a shape and a size of upward opening. In other words, an open edge of thelid side opening 28 is located on the outer side of any position of the open edge of thedrum side opening 43. - Then, in the present embodiment, the
hopper 7 performs a function as a heightened drum for storing water with a water level higher than the upper end of thedrum 4. That is, thehopper 7 performs a function as a washing drum. In addition, in the present embodiment, as mentioned above, since thecylindrical body 22, themovable lid 25 and thehopper 7 of thehousing body 20 are configured to be transparent or semitransparent, it is easy to perform visual confirmation on laundry which rise near a water surface of thehopper 7 by means of the fixinglid 24 and perform visual confirmation on laundry near the water surface from the side by means of thecylindrical body 22 and thehopper 7 during washing. In other words, visualization of the laundry is good. In addition, by providing thecylindrical body 22 to be transparent or semitransparent, visualization of internal mechanism components is also increased. Therefore, the grasping of the operating state by a user and the convenience for operations are improved. - In addition, in the present embodiment, the
hopper 7 performs a function as the heightened drum during washing. Since an approximately conical shape, i.e., a conical shape is adopted, and the laundry is guided to thedrum 4 as a dewatering drum during dewatering, thereby reliably accommodating the laundry into thedrum 4. - In addition, in the present embodiment, especially as shown in
FIG. 5 , thedamper 6 is provided at the lower part of thetub 3 and thehopper 7 as the heightened drum is formed with a light type, thereby increasing natural vibration frequency of the part supported by thedamper 6 and further reducing vibration during dewatering. - Further, in the present embodiment, the
hopper 7 is fixed to thetub 3 and cannot rotate; and on the other hand, undoubtedly, thedrum 4 is formed to be rotatable. However, the water does not leak between thedrum 4 and thehopper 7. - That is, in the present embodiment, especially as shown in
FIG. 6 , the labyrinth-type sealing part 8 is formed across regions of thehopper 7, thetub 3 and the upper end of thedrum 4, and includes: anupper side rib 81 arranged on the extendingpart 72 of thehopper 7 and extending to the lower side of a vertical direction; alower side rib 82 arranged on the upper end of thedrum 4 and extending to the upper side of the vertical direction; and anair retention part 83. Thepacking component 35 is arranged at the upper end of thetub 3 and is arranged at a position including the upper side of the vertical direction of an imaginary plane of the top part of theupper side rib 81, to seal the upper end of thetub 3 and the extendingpart 73. Thus, air of theair retention part 83 can be prevented from exceeding thepacking component 35 and leaking from thetub 3. - When the water is accumulated on the upper side of the
balancer 41 of thedrum 4, a liquid level in thelabyrinth sealing part 8 is formed to be in a same plane approximately as the top part of theupper side rib 81, and the air-filledpart 83 is formed between the liquid level and the inner circumferential surface of the extendingpart 72 above the liquid level. By forming the air-filledpart 83, even if the water in thehopper 7 moves from a place between the upper and thelower ribs part 83 since the air-filled part is already formed near thepacking component 35. In addition, since thepacking component 35 is arranged, even if the water exceeds the air-filledpart 83 and immerges, the water can be prevented from flowing to the outer side of thetub 3. Thus, the quantity of connecting components required for connecting thetub 3 with thehopper 7 can be effectively reduced. - As mentioned above, the
washing machine 1 in the present embodiment includes: adamper 6 vertically arranged from thebottom wall 21 of thehousing 2, absorbing vibration of thetub 3 and supporting the lower end of thetub 3; and ahopper 7 arranged between thedrum side opening 43 and alid side opening 28 and configured to guide throwing-in of the laundry from thelid side opening 28 to thedrum side opening 43 or taking-out of the laundry from thedrum side opening 43 to thelid side opening 28. Thus, generation of abnormal noise caused by sliding contact between the hoisting rod and thetub 3 is eliminated by removing the hoisting rod; and thedamper 6 is provided for supporting near thebottom wall 21 of thehousing 2, thereby effectively inhibiting an influence of the vibration caused by an overturning moment on thehousing 2. In addition, thehopper 7 is clamped between thehousing 2 and thedrum 4; and even if a distance between thedrum side opening 43 and thelid side opening 28 is increased, taking-out and throwing-in of laundry can be properly guided. - In addition, according to the present embodiment, the
hopper 7 is formed in an approximately conical shape, and includes: a lower end part connected with an upper end part of thedrum 4; and a large-diameterupper end part 73 formed with a diameter which gradually increases upwards from the lower end part. In other words, an inverted truncated cone shape or an approximate mortar shape is adopted. Therefore, an opening area of the upper end part of thehopper 7 can be obtained more broadly than thedrum 4, thereby further enhancing convenience of taking-out and throwing-in of the laundry. - Further, according to the present embodiment, at least part of the
housing 2 and thehopper 7 are provided to be transparent or semitransparent. Therefore, except a design appearance, visualization of a washing state and visual confirmation of a fault part can be enhanced. - In addition, according to the present embodiment, the
hopper 7 is made of the material with a specific gravity smaller than that of the materials of thetub 3 and thedrum 4. Therefore, components supported by thedamper 6 have light weight, thereby increasing natural vibration frequency of the part supported by thedamper 6 and reducing vibration during general dewatering. - Then, according to the present embodiment, the
hopper 7 performs a function as the heightened drum for storing the water with a water level higher than the upper end of thedrum 4. Therefore, the same effect as the washing machine with a simple structure and an increased volume of thedrum 4 can be obtained. - In addition, according to the present embodiment, the
hopper 7 includes: an extendingpart 72 extending from an inner circumference of thetub 3 to thedrum side opening 43; and ahopper body 71 integrally arranged vertically from the extendingpart 72. Therefore, although the material with light weight is used, the strength of thehopper 7 is effectively enhanced since the shape of the material is difficult to be bent. - Although an embodiment of the present disclosure is described above, the structure of the present embodiment is not limited to the above-mentioned contents and can be varied in any forms.
- For example, in above embodiments, a structure configured with three dampers is disclosed. However, undoubtedly, a manner of more than four dampers can also be applied as long as the manner supports the tub.
- In addition, in above embodiments, the structure that the hopper is fixed to the tub is disclosed. However, undoubtedly, a structure that the hopper is configured at the housing side can be adopted. Specifically, the structure that the hopper is fixed to the fixing lid and the housing body is adopted.
- Various variations can also be made to other structures without departing from the scope of the spirit of the present disclosure.
