Description

Drum type washing machine

The present application is a divisional application of application having application date of 2016, 8/3/2016, application number of 201680042800.7 (PCT/JP 2016/003574), and title of "drum-type washing machine".

Technical Field

The present disclosure relates to a drum type washing machine that performs at least one of a washing process, a rinsing process, and a dehydrating process.

Background

Conventionally, such a drum-type washing machine has an operation display unit including an input unit and a display unit disposed in front of an upper surface of a main body. Moreover, the following solutions are proposed: by enlarging the operation display unit, operability when a user inputs the types of the washing step, the rinsing step, the dehydrating step, and the like using the input means and visibility of the display means are improved (see patent document 1).

However, in the conventional drum-type washing machine, the operation display unit is disposed in front of the upper surface of the main body, and therefore the opening for taking out the laundry is provided below the operation display unit. Therefore, the operation display unit and the water tank provided in the main body need to be spaced apart from each other in the height direction. Therefore, the water tank is disposed at a position lower by an amount corresponding to the height of the operation display portion. As a result, when the entire body is downsized, the position of the opening for taking out the clothes located on the front surface of the body becomes low, and there is a problem that the workability of taking out the clothes becomes poor.

Detailed Description

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

Fig. 1 is an overall perspective view of a drum-type washing machine according to an embodiment of the present disclosure. Fig. 2 is an overall perspective view of the drum type washing machine when the cover is opened. Fig. 3 is a view showing a longitudinal section of the drum type washing machine. Hereinafter, the front-back direction and the up-down direction are defined as the directions shown in fig. 3.

In fig. 3, a water tub 2 is swingably supported by a buffer unit, not shown, in a main body 1 of the drum-type washing machine. In the water tub 2, a rotating drum 3 having a bottomed cylindrical shape is rotatably disposed so that the axial direction thereof is inclined downward from the front side toward the rear side. Water tub 2 has a laundry entrance 4 at the front side to the open end of rotary drum 3. The front frame 5 constitutes the front surface of the main body 1. The front frame 5 has an opening 6 at the front. When the lid 9 is opened, laundry is put into the rotary drum 3 through the laundry entrance 4 from the opening 6 or laundry is taken out from the rotary drum 3.

A large number of through holes 10 that pass through the water tub 2 are formed in the circumferential surface of the rotary drum 3. The rotary drum 3 is rotationally driven in the normal rotation direction and the reverse rotation direction by a motor 11 attached to the back surface side of the water tub 2. The water injection line 12 and the drain line 13 are connected to the water tank 2 by pipes. The water supply into the water tank 2 and the water discharge from the water tank 2 are performed by controlling the water supply valve 14 and the water discharge valve 15.

A detergent supply container 17 is disposed on the upper portion of the main body 1. Since detergent supply container 17 is disposed on the side surface side of main body 1, water tank 2 can be disposed above. Before the operation, the user opens the detergent inlet container lid 18 disposed on the top surface of the main body 1. Then, the user puts the detergent and the softener into the detergent putting container 17.

The front frame 5 of the main body 1 is formed as a vertical (including substantially vertical) plane. The lid 9 is rotatably supported by the front frame 5. The lid 9 has a rectangular shape (including a substantially rectangular shape), and the width dimension of the lid 9 is the same as (including substantially the same as) the width dimension of the main body 1. The lid 9 is configured such that, in a state where the lid 9 is closed, the upper surface of the lid 9 is flush with (includes substantially flush with) the upper surface of the main body 1, and both side surfaces of the lid 9 are flush with (includes substantially flush with) both side surfaces of the main body 1.

The lower panel 40 is rotatably supported at a position below the lid 9 of the front frame 5 of the main body 1. The lower panel 40 covers a drain filter 79 (see fig. 29) for filtering the drain from the water tank 2. In a state where the lid 9 and the lower panel 40 are closed, the front surface of the lid 9 and the front surface of the lower panel 40 are configured to be flush (including substantially flush) with each other. The width of the lower panel 40 is the same as (including substantially the same as) the width of the main body 1, as in the case of the lid 9. The two side surfaces of the lower panel 40 are flush with (include substantially flush with) the two side surfaces of the main body 1.

An operation display unit 16 is disposed on the upper portion of the lid 9. The operation display unit 16 includes an input unit and a display unit. The user can set desired operation contents, start operation, and temporarily stop operation by operating the input unit of the operation display unit 16 as necessary. The user can check the setting state and the progress state of the operation by operating the display unit of the display unit 16. The operation display unit 16 is disposed on the upper surface of the lid 9, and thus can be removed from the upper portion of the main body 1. Accordingly, water tub 2 can be disposed above, and the workability of taking out laundry from rotary drum 3 and putting laundry into rotary drum 3 can be improved.

The operation is started by opening the lid 9 having a quadrangular shape (including a substantially quadrangular shape), putting laundry into the rotary drum 3, and operating the operation display unit 16. By the start of the operation, the water injection valve 14 is opened. Then, water is injected into the detergent supply container 17, and a predetermined amount of the detergent supplied into the detergent supply container 17 is supplied into the water tank 2 through the water supply line 12 while flowing. Then, the rotary drum 3 is rotated by the motor 11, and the washing stroke is started. The laundry in the washing stroke is washed by repeating the stirring operation of being lifted up in the rotation direction and then falling down by the rotation of the rotary drum 3.

After the required washing time, the drain valve 15 is opened and the contaminated washing liquid is drained from the drain line 13. The spin drum 3 performs a spin-drying operation of rotating at a high speed, thereby dehydrating the washing liquid contained in the laundry, and then, water is supplied into the water tank 2 through the water supply line 12, thereby performing a rinsing stroke. In the rinsing stroke, the washing is repeatedly agitated by the rotation of the rotary drum 3, and rinsing is performed.

(description of the linking section)

Next, the structure of the coupling portion that rotatably supports lid 9 to front frame 5 of main body 1 will be described in detail with reference to fig. 4 to 14.

As shown in fig. 4, an upper coupling member 21 is disposed at the upper left end of the front frame 5 of the main body 1. A lower connecting member 22 is disposed at a lower portion of the left end of the front frame 5. The upper coupling member 21 and the lower coupling member 22 are fixed to a frame structure (not shown) of the main body 1, and penetrate the front frame 5 to protrude forward of the main body 1.

As shown in fig. 5, the upper connecting member 21 includes an upper arm portion 23 extending forward of the main body 1. An upper support shaft 24 extending upward of the main body 1 is provided at the tip (including the vicinity of the tip) of the upper arm portion 23. As shown in fig. 6, the lower connecting member 22 also includes a lower arm portion 25 extending forward of the main body 1, similarly to the upper connecting member 21. A lower support shaft 26 extending upward of the main body 1 is provided at the tip (including the vicinity of the tip) of the lower arm 25.

As shown in fig. 1, the lid 9 has a rectangular shape (including a substantially rectangular shape), and the width W1 of the lid 9 is equal to (including substantially equal to) the width W2 of the main body 1. In the closed state of the lid 9, both side surfaces of the lid 9 and both side surfaces of the main body 1 are flush (include substantially flush) with each other.

As shown in fig. 12, the upper support shaft portion 24 is inserted into an upper bearing member 27 fastened to the upper portion of the lid body 9. Fig. 12 shows only the upper bearing member 27, and shows a state in which the lid 9 is omitted.

As shown in fig. 11, the lower support shaft 26 is inserted into a lower bearing member 28 fastened to the lower portion of the lid 9. Thus, the two bearing

members

27 and 28 provided on the upper and lower sides of the lid body 9 are supported from below by the two upper coupling members 21 and lower coupling members 22 provided at positions separated from each other. The lid 9 covers the opening 6 of the main body 1 to be rotatable.

Fig. 13 is a cross-sectional view showing a peripheral structure of the upper coupling member 21 in a state where the lid 9 is closed. Fig. 14 is a cross-sectional view showing the peripheral structure of the upper coupling member 21 in a state where the lid 9 is opened.

The upper arm portion 23 is formed in a curved shape so as to prevent the front end of the side wall 29 of the lid body 9 from abutting the front frame body 5 in a state where the lid body 9 is opened. The upper support shaft 24 is disposed inside the lid 9 at a position close to the front face 31 and the side wall 29 so as to reduce a front-rear direction gap a (see fig. 13) between the side wall 29 of the lid 9 and the front frame 5 when the lid 9 is closed and a projection amount b (see fig. 13) from the front face end 76 of the lid 9 in the width direction of the side wall 29 on a rotation trajectory from a state in which the lid 9 is opened to a state in which the lid is closed. The front-rear direction interval a is an appearance gap when the drum-type washing machine is viewed from an oblique direction. With the above configuration, the front-rear direction interval a can be reduced, and the appearance can be improved. In addition, with the above configuration, the amount of projection b in the width direction can be reduced, and the product can be installed closer to the house wall when installed. This enables installation even in a narrow place.

On the other hand, as shown in fig. 6, the lower arm portion 25 of the lower connecting member 22 is not curved like the upper arm portion 23, but is configured to extend forward of the main body 1. This is because the lower coupling member 22 does not need to support the lower edge 32 of the lid body 9 from below, deviating from the turning locus of the side wall 29 of the lid body, as shown in fig. 9.

As shown in fig. 3, when the lid 9 is closed, the window glass 33 provided in the lid 9 is in water-tight contact with the window seal 34 attached to the water tub 2. This prevents the washing liquid in the water tank 2 from leaking to the outside of the washing machine. When the lid 9 is opened and closed, as shown in fig. 2, the latch 35 provided in the lid 9 engages with the lid lock hole 36 provided in the main body 1, and is electrically locked during operation, so that the lid 9 is not opened.

As shown in fig. 2, when an external force F1 is applied downward to the lid 9 when the lid 9 is opened, the applied load is supported by the upper connecting member 21 and the lower connecting member 22. Therefore, if the strength of the upper coupling member 21 and the lower coupling member 22 is insufficient, the upper coupling member 21 and the lower coupling member 22 are deformed to displace the position of the lid body 9. Thus, when the lid 9 is closed, the water seal between the lid 9 and the window seal 34 is broken. As a result, the washing liquid in the water tub 2 may leak out of the machine, or the position of the latch 35 may be shifted with respect to the lid lock hole 36 when the lid 9 is closed, and the lid 9 may be difficult to close.

For example, in the case of a circular lid as in the conventional example, even if the coupling members are disposed apart from each other, the coupling members cannot be separated from each other from the center line of the lid. Therefore, it is necessary to increase the thickness of the coupling member or to provide a reinforcing member, and a significant cost is required to increase the strength of the coupling portion of the lid body.

However, in the present embodiment, the cover 9 is formed in a rectangular shape (including a substantially rectangular shape), so that the two upper connecting members 21 and the lower connecting member 22 can be disposed sufficiently apart from each other. As a result, as shown in fig. 2, when external force F1 is applied to lid 9, the force acting on upper coupling member 21 and lower coupling member 22 can be reduced.

Further, although the upper coupling member 21 has a curved shape and may be weak against the external force F1 in the downward direction, the lid 9 can be supported by the lower coupling member 22 with sufficient strength to resist the downward load. This prevents deformation of the upper and

lower coupling members

21 and 22 without requiring any special reinforcement measures. This prevents leakage of the cleaning liquid due to displacement of the lid 9, and prevents deterioration of operability during closing operation of the lid 9.

Further, as shown in fig. 2, it is assumed that, in a state where the lid 9 is opened, an external force F2 is applied to the lid 9 in a superopening direction in which the lid is further opened. When the lid 9 is fully opened, the stopper piece 37 provided in the upper bearing member 27 abuts against the projection 38 provided in the upper coupling member 21, thereby forming a stopper in the superopen direction (see fig. 14). Therefore, when a load F2 is applied to the lid 9 in the superopen direction, the direction of the force acting on the upper arm portion 23 is the left direction of the main body 1 in fig. 14, that is, the direction in which the upper bearing member 27 is difficult to deform. Accordingly, it is possible to relatively easily realize a strong coupling structure of the lid body 9 without increasing the thickness of the upper coupling member 21 and the lower coupling member 22 or providing a special structure such as a reinforcing member, which leads to additional cost.

Further, although not shown, a stopper in the superopen direction may be provided also in the lower coupling member 22, similarly to the upper coupling member 21. Thus, the force acting on the upper connecting member 21 and the lower connecting member 22 is shared by the two members, and the lower bearing member 28 is less likely to be deformed.

(description of front surface shape of Drum type washing machine)

As shown in fig. 1, the lid 9 has a rectangular shape (including a substantially rectangular shape), and a width W1 is equal to (including substantially equal to) a width W2 of the main body 1. The width of the lower panel 40 covering the drain filter 79 (see fig. 29) housed in the lower portion of the main body 1 is equal to (including substantially equal to) the width W2 of the main body 1. Thus, the front surface of the drum type washing machine when viewed from the front of the product is in the shape of a flat plate. The split gap 41 between the lid 9 and the lower panel 40 is visible from the front of the drum-type washing machine, but since the lid 9 is rotated only in the horizontal direction, the split gap 41 can be suppressed to within 5mm, which is difficult to be noticed. The lower side of the lower panel 40 is recessed toward the main body 1 side to the front frame 5 of the main body 1 without disposing any component, so that the user's foot can be inserted below the lower panel 40. Thus, when taking out and putting in laundry, the user can perform work while standing closer to the main body 1.

As shown in fig. 1, the upper surface of the main body 1 and the upper surface of the lid 9 are configured to be flush (including substantially flush) with each other. Thus, the upper surface of the product is in the shape of a flat plate, and the appearance can be improved.

For example, in the case of a circular lid as in the conventional example, it is necessary to widen the gap between the periphery of the lid and the main body to some extent and to form the lid surface in a shape protruding from the main body in order to prevent interference between the lid and the main body when opening and closing the lid. The interference between the lid and the main body is greatest at the position where the opening/closing fulcrum of the lid intersects the outer periphery of the lid. If this interference is to be avoided, the gap or height difference between the cover and the main body becomes large, and it is difficult to configure the cover to have the same form as the main body in appearance.

In the present embodiment, the width W1 of the lid 9 is equal to (including substantially equal to) the width W2 of the main body 1, and thus the front frame 5 of the main body 1 is covered with the lid 9. Accordingly, the division between the periphery of the lid 9 and the main body 1 disappears, the front surface of the product can be flat, and the division gap can be reduced, so that the appearance can be improved.

As shown in fig. 2, when the lid 9 is opened, the upper coupling member 21 extends forward from the front frame 5 and is exposed. On the other hand, the lower coupling member 22 is hidden and hardly exposed at the lower edge 32 of the lid body 9 (see fig. 9). This makes it possible to improve the appearance by providing a clean appearance even when the lid 9 is opened. It is assumed that when the laundry is taken out from the opening 6 or put into the opening 6, a hanging portion of the laundry contacts the vicinity of the lower coupling member 22. In the present embodiment, since the lower coupling member 22 is covered by the lid body 9, the laundry is prevented from being caught by the lower coupling member 22. Further, the lower coupling member 22 can be prevented from contacting water dripping from the laundry, and the lower coupling member 22 can be prevented from being wetted with the washing liquid from the laundry and corroded.

(explanation of assembly of cover 9 to main body 1)

Fig. 5 is a perspective view showing the upper coupling member 21 in a state where the lid 9 is removed. Fig. 6 is a perspective view showing the lower coupling member 22 in a state where the lid 9 is removed.

As shown in fig. 5 and 6, in a state before the lid 9 is attached to the main body 1, the upper coupling member 21 and the lower coupling member 22 extend forward from the front frame 5. The upper support shaft 24 and the lower support shaft 26 extend upward by about 10 mm. As shown in fig. 7, the lid 9 is provided with an opening 42 at a position corresponding to the upper coupling member 21 on the back surface of the lid 9.

When the lid 9 is attached to the main body 1, the upper arm portion 23 of the upper connecting member 21 is inserted into the opening 42 of the lid 9, and then the lid 9 drops downward due to its own weight if the force is removed. Thereby, the upper support shaft portion 24 is inserted into the upper bearing member 27. Thus, the lid 9 is rotatably attached to the main body 1 while being supported from below by the upper coupling member 21. Further, since the lower connecting member 22 supports the lower edge 32 of the lid body 9 from below, the insertion opening portion is not required. That is, during the operation of inserting the upper arm portion 23 of the upper connecting member 21 into the opening 42, the lower support shaft portion 26 is also inserted into the lower bearing member 28. In this way, the cover 9 is attached to the main body 1.

Since the upper support shaft portion 24 and the lower support shaft portion 26 extend upward by only about 10mm, the distance from the insertion of the upper connecting member 21 into the opening 42 to the downward movement of the lid body 9 by its own weight is only about 10 mm. Therefore, the cover 9 can be attached to the main body 1 by just one operation, and thus the assembling property is improved.

Fig. 10 is a perspective view showing a peripheral structure of the coupling portion in a state where the cover 43 is removed. Fig. 11 is a perspective view of the main body and the lower part of the cover. In a state where the upper support shaft portion 24 is inserted into the upper bearing member 27 and the lower support shaft portion 26 is inserted into the lower bearing member 28, the cover 43 covering the opening 42 is attached to the lid 9. The upper surface 44 of the cover 43 is located near the lower surface 45 of the upper coupling member 21. With this configuration, upward movement of the lid 9 can be restricted, and even if the lid 9 is lifted upward, the lid 9 can be prevented from being detached from the upper connecting member 21 and the lower connecting member 22.

As shown in fig. 1, an operation display unit 16 is provided on the upper surface of the lid 9. A lead 46 drawn from the main body 1 and a lead 47 drawn from the operation display unit 16 are connected to each other by a connector 48 in the opening 42 (see fig. 10). Thus, the cover 43 also has a function of protecting the

lead wires

46 and 47 from water. The

lead wires

46 and 47 are formed by bundling a plurality of lead wires.

The lead wire 46 drawn out from the main body 1 is housed in a lead wire cover 49 shown in fig. 8. The lead wire cover 49 is attached to the upper arm portion 23 of the upper coupling member 21 from below the upper coupling member 21 to protect the lead wires 46 from water.

As shown in fig. 7 and 8, the surface 49a of the lead cover 49 that is joined to the upper arm portion 23 is configured to have the same shape (including substantially the same shape) as the upper arm portion 23. A lead wire housing portion 49b for housing the lead wire 46 drawn out from the main body 1 is provided on the surface 49a side of the lead wire cover 49 that is joined to the upper arm portion 23. A pressing portion 77 that presses the lead 46 housed in the lead housing portion 49b is disposed in the lead housing portion 49b. The lead 46 is housed in the lead housing portion 49b, and the movement of the lead 46 is prevented by pressing the lead 46 by the pressing portion 77. In this state, the lead cover 49 is engaged with the lower surface of the upper arm 23.

In a state where the lead cover 49 is engaged with the lower surface of the upper arm 23, a gap of about 2mm is present between the lead 46 and the lower surface of the upper arm 23. The lead 46 drawn out from the lead housing portion 49b extends along the vicinity of the central axis 24a of the upper support shaft portion 24 inside the opening portion 42 of the lid 9 (see fig. 7). The lead 46 extending in the opening 42 is engaged with the inside of the opening 42 at an arbitrary position (for example, a position of 100mm at the tip) by a fixing pin 78. The fixing pin 78 engages the lead 46 in the opening 42 at a position slightly spaced apart from the vicinity of the central axis 24a of the upper support shaft 24. The leading end portion of the lead wire 46 fixed by the fixing pin 78 and the lead wire 47 drawn out from the operation display portion 16 are connected in the opening 42 by the connector 48. The opening 42 is closed by engaging the cover 43 with the lid 9.

The pressing portion 77 is configured such that the distance between the pressing portion 77 and the bottom surface of the lead wire housing portion 49b is the same size (including substantially the same size) as the radius of the lead wire 46. The pressing portion 77 is disposed near the central axis 24a of the upper support shaft 24. The lead cover 49 includes a lead-out portion 99 for drawing out the lead 46 from the lead housing portion 49b in the vicinity of the pressing portion 77. The lead portion 99 is located in the vicinity of the central axis 24 a. Thus, the lead 46 drawn out from the lead housing portion 49B can be easily brought close to the central axis 24a of the upper support shaft portion 24 in a range B (see fig. 7) from a portion where the lead 46 is bent to the portion engaged with the opening 42 by the fixing pin 78. The lead 46 has no lead portion extending at a right angle (including a substantially right angle) to the central axis 24a of the upper support shaft 24 in a range B from the bent portion of the lead 46 to the engagement with the opening 42 by the fixing pin 78. Since the stress applied to the lead 46 by opening and closing the lid 9 is changed from the concentrated stress in the bending direction having a large influence on the disconnection to the stress in the twisting direction, the possibility of disconnection of the lead 46 can be reduced.

Even when the lid 9 is opened and closed, the lead 46 is not stressed and does not move in the section C (see fig. 7) housed in the lead cover 49 and the section from the section C to the position where the lead is engaged with the opening 42 by the fixing pin 78. Therefore, the lead 46 can be prevented from being broken by the stress. Further, since the outside is avoided, corrosion and deterioration due to adhesion of contaminants such as water and foreign matter entering from the outside can be prevented.

The

lead wires

46 and 47 are configured by bundling a plurality of lead wires and winding the bundled lead wires with a tape. In addition, a plurality of

leads

46 and 47 may be provided. Since the opening 42 of the lead wire 46 is provided in the upper side surface portion 65 where the window glass 33 is not present, it is not necessary to make the window glass 33 small to lead the lead wire 46. Since the window glass 33 is in water-tight contact with a window seal 34 (see fig. 3) attached to the water tub 2 so as to cover the opening 6, it is not necessary to make the window seal 34 and the opening 6 small. Therefore, the ease of the work of taking out and putting in the laundry is not impaired.

The upper surface 44 of the cover 43 approaches the lead cover 49 (see fig. 10). In the present embodiment, since the cover 43 rotates together with the lid 9, the cover 43 and the fixed lead wire cover 49 have a clearance of about 2mm to avoid friction therebetween during the opening and closing operation of the lid 9. With the above configuration, the engagement amount between the upper support shaft 24 and the lower support shaft 26 is about 10mm, and therefore even if the lid 9 is lifted upward, the lid 9 can be prevented from coming off from the upper coupling member 21 and the lower coupling member 22. In addition, it is possible to prevent contaminants such as detergent that have entered from the outside from adhering to the

leads

46 and 47, and to prevent the

leads

46 and 47 from being corroded and deteriorated.

(explanation of the structure of the lid 9)

Fig. 20 is an exploded perspective view of the lid 9. Next, the structure of the lid 9 will be described in detail with reference to fig. 20.

The cover 50 has a quadrangular shape (including a substantially quadrangular shape), and has a circular hole at the center. A lid back plate 51 having a rectangular shape (including a substantially rectangular shape) similar to the lid 50 and having a circular hole 52 in the center is fastened to the back surface side of the lid 50. The lid back plate 51 is a box-shaped skeleton member having two side walls and a lower wall. The transparent window glass 33 is sandwiched between the lid back plate 51 and the lid 50 so as to enter the circular hole 52 of the lid back plate 51. An upper bearing member 27 is fastened to the left upper portion of the lid back plate 51, and a lower bearing member 28 is fastened to the left lower portion of the lid back plate 51.

On the surface side of the cover 50, a ring-shaped decorative plate 58 is fitted into the hole. The surface side of the cover 50 is formed with a tapered slope 59 by the decorative plate 58. A transparent window cover 60 having a rectangular shape (including a substantially rectangular shape) is provided on the front surface side of the cover 50. The window cover 60 includes a plurality of engagement holes 60c (see fig. 22) on both side surfaces 60a. The engagement claw 51a formed on the side wall of the lid back plate 51 is engaged with the engagement hole 60c and temporarily fixed to the window cover 60.

A stepped portion 60b is provided on the front surface side of both side surfaces 60a of the window cover 60 (see fig. 23). The

frame members

73 and 76 are attached to both side surfaces of the lid body 9 by sliding from above to below so as to cover the lid back plate 51 and the side surface 60a of the window cover 60. The step 60b of the window cover 60 is covered with the

frame members

73, 76. The fixed portion of the window cover 60 is covered by the

frame members

73, 76, and therefore the window cover 60 is shaped to constitute the entire front surface of the lid body 9. This makes the front surface of the lid 9 flat, thereby improving the appearance.

The front surface of the window cover 60 has a completely flat plate shape. As shown in fig. 19B, the rear surface of the window cover 60 abuts against the outer edge 61 of the decorative plate 58 in the front-rear direction. The inner edge 62 of the decorative plate 58 covers the vicinity of the nip 63 of the transparent window glass 33. The outer edge 61 and the inner edge 62 of the decorative plate 58 are continued by the tapered slope 59.

A substantially circular decorative plate 58 is provided between the rear surface of the window cover 60 and the window glass 33. A cylindrical (including substantially cylindrical) rib 88 is provided on the rear surface of the window cover 60 so as to be close to the outer edge 61 of the decorative plate 58 (see fig. 19B). The range of the rear surface of the window cover 60 larger than the diameter of the rib 88 constitutes the opaque-coated coating range 64, and the portion surrounded by the rib 88 becomes the region 82 having high transparency (see fig. 19A and 19B). The decorative plate 58 is painted or plated in a color different from the painting range 64 of the window cover 60, and is in an appearance color that can be observed through the transparent window cover 60.

In the present embodiment, the main body 1 is white, the paint color of the paint range 64 on the rear surface of the window cover 60 is white similar to that of the main body 1, and the decorative plate 58 is plated. Thus, it can be seen that the ring-shaped plated decorative plate 58 surrounds the transparent window glass 33, and can provide an appearance with a feeling of impact in design. Further, if the decorative plate 58 is formed in another coating color, the model development can be easily performed.

Further, since the cover 50 is a member that is not visible from the appearance and does not require painting, it can be formed of a resin that is inexpensive and does not require a fear of being penetrated by a liquid detergent or the like. In addition, in the case of coating, in order to ensure the adhesion of the coating, ABS resin or the like, which is expensive, needs to be used. When ABS resin is used, it is necessary to match the chemical resistance specifications so that chemicals such as liquid detergent do not deteriorate even if adhered, and the price is further increased.

For example, when tap water or detergent is splashed on the lid 9, water may enter the lid 9 through a fitting gap with the operation display unit 16 fitted to the upper portion of the lid 9. In the present embodiment, since the ribs 88 are disposed close to the outer edge 61 of the decorative panel 58, water flows around the outer periphery of the ribs 88, and water can be prevented from entering the high-transparency region 82 surrounded by the ribs 88. Moreover, water can be prevented from flowing to the surface side of the tapered slope 59. If water or the like enters the region 82 having high transparency, the quality is deteriorated as an external dirt, and therefore, a design having high resistance to the external dirt can be performed.

The rib 88 on the rear surface of the window cover 60 also has an effect of facilitating masking work when painting is performed. In general, if there is a region where coating is impossible, the surrounding must be masked to prevent the paint from entering, but in this case, masking work is difficult, and the yield is lowered. Therefore, by bringing a masking jig (not shown) into contact with the rib 88, masking can be reliably performed in a narrow area, and thus workability of coating can be improved.

(description of the handle)

Fig. 24 is a plan view for explaining the handle, the connecting rod, and the latch, and shows a state where the handle 55, the connecting rod 57, and the latch 35 are attached to the lid back plate 51. Further, the cover 50 is not shown. The latch 35 is provided near the center line of the hole portion 52 to ensure water-tightness. The handle 55 is disposed at the upper right end portion of the lid 9. By raising the position of the handle 55 in this way, the user does not need to bend down when opening the lid 9. Thus, the operability of opening and closing of the lid body 9 is improved.

Since the handle 55 is disposed on the upper portion of the lid 9, the handle 55 is disposed apart from the latch 35. Thus, the connecting rod 57 is interposed between the handle 55 and the latch 35. The handle 55 is rotated toward the front side of the lid body 9, and the rotation of the handle 55 is transmitted to the latch 35 through the coupling rod 57. Then, the latch bar 35 is turned toward the width direction inside of the cover 9. The latch 35 is rotated to disengage the latch 35 from the main body 1, so that the lid 9 can be rotated. The connecting rod 57 is made of a high-rigidity steel wire material, and is rotatably held by bearing

portions

80 and 81 formed in the cover back plate 51. Further, a step 97 provided at one end of the connecting rod 57 abuts on the handle 55, and a step 98 provided at the other end of the connecting rod 57 abuts on the latch 35.

Fig. 25 is a perspective view of a main part of the lid body, showing a state in which the handle 55 and the coupling rod 57 are attached. Fig. 26 is a perspective view of a main portion of the cover body, showing an attached state of the latch 35.

In the vicinity of the right center line of the hole 52 of the lid back plate 51, the latch 35 is rotatably attached via a latch shaft 53a (see fig. 7). A latch spring 54 that urges the latch 35 is provided. The latch spring 54 biases the latch 35 so that the engagement claw of the latch 35 is turned outward in the width direction of the cover 9.

Further, a handle 55 is rotatably attached to the rear surface side of the upper right side of the lid back plate 51. The handle 55 is pushed downward by a handle spring 56 with a weak biasing force (see fig. 20). The connecting rod 57 is rotatably attached to the lid back plate 51. One end of a connecting rod 57 provided with a bent portion abuts on the latch 35, and the other end abuts on the handle 55, and the connecting rod 57 has a function of transmitting the rotation of the handle 55 to the latch 35. That is, when the user opens the lid 9 in a state where the lid 9 is closed, if the handle 55 is pulled toward the lid 9, the engagement claw of the latch 35 that engages with the lid lock hole 36 provided on the main body 1 side is turned inward in the width direction of the lid 9, and is opened from the engaged state. Thereby, the lid 9 is in an openable state. Further, the latch 35 and the handle 55 are also illustrated in fig. 2 viewed from the lid back plate 51 side which becomes the back surface of the lid body 9.

If the user pulls the handle 55 toward the front surface side of the lid 9 in order to open the lid 9, the handle 55 rotates about the shaft 84 toward the front surface of the lid 9, and presses the step portion 97 of the coupling rod 57 as an abutting portion. As a result, the coupling rod 57 pivots about the

bearings

80 and 81, and presses the latch 35 via the step 98. As shown in fig. 26, the latch 35 rotates the engaging claw of the latch 35 in the direction of the main body 1 of the lid body 9 about the shaft portion 85 against the urging force of the latch spring 54, and disengages from the lid locking hole 36. This allows the lid 9 to be opened.

In order to easily open the cover 9, it is necessary to transmit the rotation of the handle 55 to the latch 35 without loss. If the handle 55 and the latch 35 are arranged separately, the connecting rod 57 connecting the handle 55 and the latch 35 becomes long, and therefore the connecting rod 57 is likely to be deformed such as twisted, and the movement of the connecting rod 57 may be deteriorated.

In the present embodiment, a high steel wire material used for a spring or the like is used for the connecting rod 57, and thus sufficient torsional rigidity can be obtained even if the connecting rod is configured to have a relatively small diameter (for example, a diameter of 3.2 mm). Further, since the shape of the connecting rod 57 can be a simple shape with the

step portions

97 and 98 provided at both ends, the processing is also easy and the manufacturing can be performed at low cost.

In order to pivot the latch 35 to a state where the lid 9 can be opened, the pivot angle θ of the connecting rod 57 needs to be, for example, about θ =20 °. The torsion angle of the connecting rod 57 is set such that the torque T =220Nmm based on the urging force of the latch spring 54 acts

Is composed of

And (6) exporting.

In the present embodiment, the length L of the rotating portion of the connecting rod 57 is set to L =242mm, and the transverse elastic modulus G of the high-steel wire rod as the material of the connecting rod 57 is set to G =78500N/mm ² The polar moment of inertia IP of the connecting rod 57 is set to IP =10.3mm ⁴ . In this case, the twist angle of the connecting rod 57 is calculated according to the above calculation formula

Converge to

On the left and right sides, the amount of this deformation may be estimated to set the rotation angle of the handle 55.

Thus, if the twist angle of the connecting rod 57 is set

Converging within the range of about two degrees of the normal rotation angle θ can reduce the movement of the handle 55, and therefore the thickness of the lid 9 in the front-rear direction can be reduced. The amount of the thickness by which the lid body 9 is thinned can be utilized as an effective space of the main body 1.

Since the lid back plate 51 is a resin molded product, warpage due to molding occurs. However, the connecting rod 57 is elongated, and even if the lid back plate 51 is warped by about 2mm with respect to the height of 240mm, the connecting rod 57 is easily bent in the longitudinal direction and easily adapted, and does not hinder the rotation of the connecting rod 57.

(explanation of the body facing the handle 55)

Fig. 27 is an upper perspective view of the main body and the lid body, and shows a structure around the handle 55 in a state where the lid body 9 is closed. Fig. 28 is a longitudinal cross section showing a peripheral structure of the handle, and shows a peripheral structure of the handle 55 in a state where the lid 9 is closed.

The handle 55 is provided on the back side of the upper portion of the lid 9. A recess 86 is provided on the front upper surface of the main body 1 at a position facing the handle 55.

In a state where the lid 9 is closed, the handle 55 is not visible from the front surface but slightly visible from above. This can suppress the feeling of presence of the handle 55 in appearance. When the user wants to open the lid 9 and to put his hand on the handle 55, a sufficient space for inserting his hand is secured by the recess 86 provided on the upper surface of the main body 1. Therefore, the convenience of the user is not impaired. The concave portion 86 is similarly not visible from the front surface, and can be designed to have a flat appearance over the entire surface. Further, since the concave portion 86 can be clearly visually recognized when viewed from above, the user can recognize the position of the handle 55 when the lid body 9 is opened.

(description of the construction of the operation display section)

As shown in fig. 16, a space surrounded by the cover 50 and the cover back plate 51 is formed on the upper surface 66 of the cover 9. As shown in fig. 17, the operation display unit 16 is fitted into the space from above the lid 9. The operation display unit 16 is provided with an operation unit, which is an input unit for a user to select an operation program such as a "standard program" for performing standard washing, rinsing, and spin-drying, and a "reinforcement program" for washing stubborn-dirt laundry, from above, and a display unit, which is a display unit for displaying an operation state by emitting light from an LED (light emitting diode) or the like so as to be visible from above.

As shown in fig. 19B, an operation display sheet 67 on which an operation portion and a display portion are printed is arranged on the upper surface of the cover 9. As shown in fig. 19B, an operation display substrate 68 mounted with a tact switch, an LED, an electronic circuit, and the like is fastened to the back surface side of the operation display panel 67. An intermediate member 69 for guiding an operation from the surface by a user to a tact switch or guiding light emission of the LED to the surface side is sandwiched between the operation display panel 67 and the operation display substrate 68. In this way, the operation display unit 16 as shown in fig. 15 is configured.

For example, in the case where the cover is circular as in the conventional example, as shown in fig. 34, the operation display unit 500 is generally disposed in front of the upper portion of the main body 100 in view of operability and visual confirmation for the user.

However, as in the present embodiment, when the lid 9 has a quadrangular shape (including a substantially quadrangular shape) and a shape having a width dimension equal to (including substantially equal to) that of the main body 1, the operation display portion 16 can be disposed at any position among the upper portion of the front surface of the lid 9, the upper surface 66 of the lid 9, and the front portion of the top surface of the main body 1.

For example, if the operation display unit 16 is disposed on the upper portion of the front surface of the cover 9, a plurality of displays related to operations and displays appear on the front surface of the product. With this structure, it is difficult to make the front surface of the lid 9 into a completely flat plate shape. Further, it is difficult to make the fitting portion as small as possible in a sharp configuration when viewed from the front.

Further, if the operation display portion 16 is disposed on the front portion of the top surface of the main body 1, the operation display portion 16 is retracted from the front surface of the product by an amount corresponding to the thickness of the cover 9, and the convenience of the user in performing the operation or viewing the display is deteriorated. That is, the convenience of use is deteriorated.

Therefore, in the present embodiment, the operation display unit 16 is disposed on the upper surface 66 of the lid 9. With this configuration, the front surface of the lid 9 is completely flat, and the fitting portion that can be seen from the front can be provided only as the split gap 41 with the lower panel 40, thereby achieving a clean appearance. In recent years, there has been an increasing number of cases where a drum-type washing machine and a wash basin are placed side by side, and there has been a demand for a design that provides an installation space compatible with other appliances even when not in use. In the present embodiment, the configuration described above can be adjusted to the installation space in terms of the appearance of the facility. Further, when the user operates the operation display unit 16, the operation display unit 16 is disposed at a position closest to the front surface and capable of being visually confirmed and operated from above with a natural line of sight, and thus the usability can be improved.

Further, by disposing the operation display portion 16 on the lid 9, the operation display portion can be removed from the main body 1, and the water tank 2 can be disposed upward by an amount corresponding to the height (size) of the operation display portion. By disposing water tub 2 above, the workability of taking out laundry from rotary drum 3 and putting laundry into rotary drum 3 is improved.

In addition, with this configuration, it is necessary to connect the lid 9 on which the operation display portion 16 is disposed and the main body 1 on which the electric components such as the motor 11 are disposed, via the

lead wires

46 and 47. In the present embodiment, as shown in fig. 7 and 10, a lead 47 drawn from the operation display portion 16 and a lead 46 drawn from the main body 1 are connected to an opening 42 on the back surface of the cover 9 by a connector 48. With this structure, the assembling property is improved. Further, since the lead is covered with the cover 43 and the lead cover 49 in a waterproof manner, deterioration of the lead due to intrusion of the detergent liquid or the like can be prevented.

As shown in fig. 15, a plurality of engaging portions 70 are provided at a lower portion of the operation display portion 16. As shown in fig. 16, an engagement portion 71 is provided on the lid back plate 51 at a position corresponding to the engagement portion 70. As shown in fig. 18, the cover 50 is provided with an engaging portion 72. Fig. 18 is a perspective view of a main part of the window cover 60 in a state where the window cover is removed. Fig. 17 is a perspective view of a main portion of the operation display unit 16 in a state where the cover is inserted from above. In fig. 17, the plurality of engaging

portions

70, 71, and 72 are located at positions not engaged with each other, and the operation display portion 16 is located at a position not further moved downward. When the operation display unit 16 moves in the left direction (c direction) from this position, the

engagement portions

70 and 71 and the

engagement portions

70 and 72 are in the engaged state, and the operation display unit 16 converges to the predetermined position. Thereafter, the frame member 73 is inserted into the right side wall of the lid body 9 from above. The frame member 73 restricts movement of the operation display unit 16 in the right direction, and prevents the

engagement portions

70, 71, and 72 from coming off.

Fig. 18 is a perspective view of a main portion in a state where the engaging portion 70 is engaged with the engaging portion 72 and the frame member 73 is placed on the right side wall of the cover 9. The movement of the operation display unit 16 in the left direction is restricted by the engaging unit 70, the engaging unit 71, and the engaging unit 72. The movement of the operation display portion 16 in the right direction is restricted by the frame member 73. Since the engaging amount of the engaging

portions

70, 71, and 72 is enough to be about 5mm, the amount of movement in the left direction after the operation display portion 16 is inserted from above is also as small as about 5mm, and the ease of assembly of the operation display portion 16 to the cover 9 is improved.

Further, by providing the plurality of engaging

portions

70, 71, and 72, the operation display portion 16 is firmly held at a predetermined position where it does not move further downward, and is prevented from floating upward. If the operation display unit 16 floats upward, as shown in fig. 19B, a fitting gap 74 between the operation display unit 16 and the lid back plate 51 and a fitting gap 75 between the operation display unit 16 and the window cover 60 become large. When the

fitting gaps

74 and 75 are large, not only the appearance quality is deteriorated, but also a problem may occur in that liquid detergent or dirt enters the inside of the lid body 9 through the

fitting gaps

74 and 75, causing malfunction of the operation display substrate 68. Thus, the plurality of engaging

portions

70, 71, 72 are provided at intervals that can sufficiently restrict the floating over the entire width, for example, at intervals of about 100mm, and the

fitting gaps

74, 75 can be suppressed to be small over the entire width. This makes it possible to provide the operation display unit 16 having excellent design and high reliability. Further, a frame member 73 may be further provided on the left side wall of the lid body 9, and the color of the main body 1 may be changed by painting or the like to give a design impact feeling.

The width of the operation display unit 16 is the same as (including substantially the same as) the width W1 of the lid 9, and a relatively wide space can be provided. On the other hand, the dimension of the longitudinal width W3 can only be an amount corresponding to the thickness of the lid body 9 as shown in fig. 15. Further, there is a restriction that the thickness of the lid 9 is intended to be reduced to a small size to secure a space on the main body 1 side. In addition, the operation display unit 16 needs to have a certain thickness in order to be arranged so that the display of the washing time and the like corresponding to the plurality of operation programs and the selection button can be easily observed. The plurality of engaging

portions

70, 71, and 72 can hold the operation display portion 16 in a space-saving manner as compared with a general screw fastening. Since the operation display unit 16 can be enlarged by reducing the space of the fastening member, it is possible to arrange the fastening member more easily. Further, even if the screw fastening is not performed, the frame member 73 can prevent the operation display portion 16 from being detached from the cover 9, and therefore, the fitting gap with the cover 9 can be suppressed to be small.

(description of the lower Panel 40)

Fig. 29 is a perspective view of the lower panel 40 in an open state. Fig. 30 is a perspective view showing a left side coupling portion of the lower panel 40. Fig. 31 is a perspective view showing a right side coupling portion of the lower panel 40. Fig. 32 is a perspective view illustrating an assembled state of the left side coupling portion of the lower panel 40. Fig. 33 is a perspective view illustrating an assembled state of the left side coupling portion of the lower panel 40.

A lower panel 40 is rotatably supported at a position below the lid 9 in the front frame 5 of the main body 1. A drain filter 79 for filtering the drain water from the water tank 2 is disposed at a lower portion of the front frame 5 of the main body 1. The lower panel 40 covers the drain filter 79. The lower panel 40 has a width equal to (including substantially equal to) the width W2 of the main body 1.

As shown in fig. 30, a left shaft portion 89 is formed in a lower left portion of the lower panel 40 so as to face a side surface of the lower panel 40. The left shaft portion 89 has a non-circular outer shape and incorporates a damper device (not shown). An L-shaped claw portion 90 having a tip bent toward the left shaft portion 89 is disposed adjacent to the left shaft portion 89. In addition, an inclined rib 91 that gradually decreases toward the side surface of the lower panel 40 is disposed on the left shaft portion 89 at a position facing the claw portion 90.

The front frame 5 of the main body 1 is provided with a left bearing 92 into which the left shaft 89 of the lower panel 40 is inserted. A side surface of the left bearing portion 92 is formed with an inclined surface 93 which gradually protrudes forward toward the outside. Further, a restricting rib 94 is disposed so as to protrude from an outer end surface of the left bearing portion 92.

As shown in fig. 31, a cylindrical right shaft portion 95 protruding in the direction of the left shaft portion 89 is disposed at the right lower portion of the lower panel 40. A right bearing portion 96 into which the right shaft portion 95 is inserted is disposed in the front housing 5 of the main body 1.

The left shaft portion 89 of the lower panel 40 is inserted into the left bearing portion 92, the right shaft portion 95 of the lower panel 40 is inserted into the right bearing portion 96, and the lower panel 40 slides in the left direction in fig. 30 and 31. Along with the sliding of the lower panel 40, the claw portion 90 disposed adjacent to the left shaft portion 89 moves along the side surface of the left bearing portion 92, and goes over the inclined surface 93 to engage with the outer end surface of the left bearing portion 92. The claw portion 90 is engaged with the outer end surface of the left bearing portion 92, thereby preventing the lower panel 40 from moving in the direction of detachment.

The lower panel 40 is rotated, whereby the drain filter 79 is exposed. Also, the thread ends and the like attached to the drain filter 79 can be removed by attaching and detaching the drain filter 79.

The lower panel 40 incorporates a damper device in the left shaft portion 89. Thus, when the lower panel 40 is rotated, the damper device functions to apply resistance to the rotation of the left shaft portion 89, thereby attenuating the opening/closing speed. The opening/closing speed of the lower panel 40 is reduced, whereby the lower panel 40 can be prevented from being damaged, and the opening/closing operation of the lower panel 40 can be performed safely.

When the lower panel 40 is opened, the pawl portion 90 abuts against the restricting rib 94 to restrict the rotation of the lower panel 40. In this state, the inclined rib 91 abuts against the left bearing portion 92. When a force is applied in a direction to further rotate the lower panel 40 in a state where the rotation of the lower panel 40 is restricted, the inclined rib 91 abuts against the left bearing portion 89, and therefore the lower panel 40 is moved in the right direction in fig. 32 by the inclined rib 91. The claw portion 90 engages with the outer end surface of the left bearing portion 92, but as shown in fig. 33, the claw portion 90 is flexibly deformed so as to be separated from the outer end surface of the left bearing portion 92 as the lower panel 40 moves. When the lower panel 40 further rotates, the claw portion 90 deforms and separates from the outer end surface of the left bearing portion 83. As a result, the lower panel 40 is removed from the main body 1.

As described above, in the present embodiment, when a force is applied in a direction in which the lower panel 40 is further opened in a state in which the lower panel 40 is opened, the lower panel 40 is removed from the main body 1 without being damaged. Therefore, even if an excessive load is applied due to erroneous use or the like, the lower panel 40 can be mounted again while preventing damage.

In the present embodiment, the lid 9 has a rectangular shape, but is not limited to this. For example, the lid 9 may have a shape in which a part thereof is cut or a part thereof bulges.

Further, the operation display portion 16 is disposed on the upper surface of the lid 9, but is not limited thereto. For example, the operation display unit 16 may be disposed on the upper front surface of the lid 9.
