Description

Drum washing machine Invention field

The present disclosure relates to a drum washing machine that performs at least one of the washing step, the washing step, and the dehydrating step.

Background of the invention

In the past, such a drum-type washing machine was provided with an operation display unit including an input mechanism and a display mechanism on the upper and front portion of the main body. Moreover, it has been proposed to enlarge the operation display unit to improve the user's operability when using the input mechanism to input the types of washing steps, washing steps, and dehydration steps, as well as the visibility of the display mechanism (see patent Literature 1).

However, in the above-mentioned conventional drum-type washing machine, since the operation display part is arrange|positioned at the upper front part, the opening part for laundry removal is provided below the operation display part. For this reason, there must be an interval in the height direction between the operation display part and the water tank provided inside the main body. Therefore, the water tank is arranged at a low position equal to the height of the operation display part. As a result, when the entire main body has been miniaturized, the position of the opening for taking out the clothes at the front of the main body has been lowered, and there is a problem that the workability of taking out clothes is deteriorated.

The form used to implement the invention

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In addition, the present invention is not limited by this 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 state when the cover of the drum-type washing machine is opened. Fig. 3 is a view showing a longitudinal section of the drum-type washing machine. Hereinafter, the front-rear direction and the up-down direction are defined in the directions shown in FIG. 3.

In Fig. 3, in the main body 1 of the drum-type washing machine, the water tank 2 is supported by a buffer mechanism not shown in the figure, and is formed in a shakeable state. A bottomed cylindrical rotating drum 3 is arranged in the water tank 2. The axis of the rotating drum 3 of the rotating drum 3 is inclined downward from the front side to the rear side, and the rotating drum 3 is rotatably arranged in the water tank 2 Inside. The water tank 2 is provided with a clothes inlet 4 communicating with the open end of the rotating drum 3 on the front side. The front frame 5 constitutes the front surface of the main body 1. The front frame body 5 is provided with an opening 6 at the front. The cover 9 is opened to be in an open state, thereby taking out the laundry from the rotating drum 3 through the laundry inlet 4 from the opening 6 or putting the laundry into the rotating drum 3.

A plurality of through holes 10 communicating with the inside of the water tank 2 are formed on the peripheral surface of the rotating drum 3. The motor 11 installed on the back side of the water tank 2 drives the rotating drum 3 to rotate in the forward and reverse directions. A water injection pipe 12 and a drain pipe 13 are connected to the water tank 2 piping. The water filling and draining into the water tank 2 are performed by the control of the water filling valve 14 and the drain valve 15.

A lotion injection box 17 is arranged on the upper part of the main body 1. If the lotion injection box 17 is arranged on the side surface of the main body 1, the water tank 2 can be arranged above. The user first opens the lotion injection box cover 18 arranged on the top surface of the main body 1 before operation. Then, the user puts lotion and softener into the lotion input box 17.

The front frame 5 of the main body 1 is formed as a vertical (including slightly vertical) plane. The cover body 9 is supported on the front frame body 5 so that it can rotate freely. The cover 9 is rectangular (including a slightly rectangular shape), and the lateral width of the cover 9 is the same as the lateral width of the main body 1 (including slightly the same). The cover 9 is configured such that when the cover 9 is closed, the upper surface of the cover 9 becomes the same surface as the upper surface of the main body 1 (including substantially the same surface), and the two side surfaces of the cover 9 become the same as the upper surface of the main body 1. The two sides are the same (including slightly the same side).

The front frame 5 of the main body 1 supports the lower panel 40 at a position below the cover 9 so as to be in a freely rotatable state. The lower panel 40 covers a drain filter 79 for filtering the drain from the water tank 2 (refer to FIG. 29). When the lid body 9 and the lower panel 40 are in a closed state, the front face of the lid body 9 and the front face of the lower panel 40 are formed on the same surface (including substantially the same surface). The lower panel 40 is the same as the cover 9 and has the same horizontal width as the main body 1 (including slightly the same). In addition, the two side surfaces of the lower panel 40 are configured to be the same surface (including substantially the same surface) as the two side surfaces of the main body 1.

An operation display unit 16 is arranged on the upper part of the cover 9. The operation display unit 16 includes an input unit and a display unit. The user operates the input unit of the operation display unit 16 as needed, thereby setting the desired operation content, starting operation, and temporarily stopping. In addition, the user can confirm the setting status and progress status of the operation by operating the display unit of the display unit 16. The operation display part 16 is arranged on the upper surface of the cover 9 so that the operation display part can be eliminated from the upper part of the main body 1. Thereby, the water tank 2 can be arranged above, and the rotation The drum 3 is easy to take out and put out the laundry.

Open the cover 9 in the quadrangular shape (including the slightly quadrangular shape), put the laundry into the rotating drum 3, and then operate the operation display unit 16 to start the operation. With the start of the operation, the water injection valve 14 is opened. Then, water is injected into the lotion injection box 17, while flushing out the lotion in the lotion injection box 17, a predetermined amount of water is injected into the water tank 2 through the water injection pipe 12. Next, the motor 11 drives the rotating drum 3 to rotate, and the washing process starts. In the washing process, the laundry is washed by the rotation of the rotating drum 3 to repeat the stirring action of being lifted and then dropped in the rotating direction to perform washing.

After the required washing time, the drain valve 15 will be opened to allow the dirty washing liquid to drain from the drain pipe 13. The spinning drum 3 spins at a high speed to dehydrate the washing liquid contained in the laundry. After that, water is injected into the water tank 2 from the water injection pipe 12 to perform a washing process. In this washing process, the washing clothes will also repeat the stirring action by the rotation of the rotating drum 3 to perform washing.

(Description of the connection part)

Hereinafter, referring to FIGS. 4 to 14, the structure of the connecting portion that rotatably supports the cover 9 to the front frame 5 of the main body 1 will be described in detail.

As shown in FIG. 4, an upper connecting member 21 is arranged on the upper left end of the front frame 5 of the main body 1. A lower connecting member 22 is arranged at the lower left end of the front frame body 5. The upper connecting member 21 and the lower connecting member 22 are frame structures (not shown in the figure) fixed to the main body 1 and penetrate the front frame 5 to protrude in front of the main body 1.

As shown in FIG. 5, the upper connecting member 21 includes an extension toward the front of the main body 1. Stretched upper arm 23. At the front end of the upper arm portion 23 (including the vicinity of the front end), an upper support shaft portion 24 extending upward of the main body 1 is provided. As shown in FIG. 6, the lower connecting member 22 also includes a lower arm portion 25 extending toward the front of the main body 1 like the upper connecting member 21. At the front end (including the vicinity of the front end) of the lower arm portion 25 is provided a lower support shaft portion 26 extending upward of the main body 1.

As shown in FIG. 1, the cover 9 has a quadrangular shape (including a substantially quadrangular shape), and the width W1 of the cover 9 is equal to (including slightly equal) the width W2 of the main body 1. In the closed state of the cover body 9, the two side surfaces of the cover body 9 and the two side surfaces of the main body 1 are formed on the same surface (including substantially the same surface).

As shown in FIG. 12, the upper support shaft portion 24 is inserted into the upper bearing member 27 which is joined to the upper portion of the cover 9. Furthermore, FIG. 12 only shows the upper bearing member 27 and shows the state where the cover 9 is omitted.

As shown in FIG. 11, the lower support shaft portion 26 is inserted into the lower bearing member 28 which is joined to the lower portion of the cover 9. In this way, the two bearing members 27 and 28 provided on the upper and lower sides of the cover 9 are supported from below by the two upper connecting member 21 and the lower connecting member 22 provided at positions away from each other. In addition, the cover 9 rotatably covers the opening 6 of the main body 1.

FIG. 13 is a view showing a cross section of the peripheral structure of the connecting member 21 in a state where the lid body 9 is closed. FIG. 14 is a view showing a cross section of the peripheral structure of the connecting member 21 in a state where the lid body 9 is opened.

The upper arm portion 23 is formed in a curved shape so that the front end of the side wall 29 of the cover body 9 does not abut the front frame body 5 when the cover body 9 is opened. Also, in order to close the side wall 29 of the cover 9 and the front and rear of the front frame 5 Directional interval a (refer to FIG. 13), and the amount of protrusion b in the width direction from the front end 76 of the cover 9 from the side wall 29 in the rotation track from the open state to the closed state of the lid 9 (refer to FIG. 13 ) It is suppressed to be small, and the upper pivot portion 24 is arranged inside the cover 9 and is arranged close to the front face 31 and the side wall 29. The interval a in the front-rear direction becomes an apparent interval when the drum-type washing machine is viewed from an oblique direction. With the above configuration, the interval a in the front-rear direction can be reduced, and the design can be improved. Moreover, with the above-mentioned structure, the protrusion b in the width direction can be reduced, and the product can be installed close to the wall of the house when the product is installed. With this, it can be installed even in narrow places.

On the other hand, as shown in FIG. 6, the lower arm portion 25 of the lower connecting member 22 is not formed in the curved shape of the upper arm portion 23 but is configured to extend toward the front of the main body 1. This is because, as shown in FIG. 9, because the lower connecting member 22 supports the lower edge 32 of the cover 9 from below, it is not necessary to release the rotation track of the side wall 29 of the cover.

As shown in FIG. 3, when the lid 9 is closed, the window glass 33 provided on the lid 9 is brought into contact with the window packing 34 installed on the sink 2 in a water-sealed manner. This prevents the washing liquid in the water tank 2 from leaking out of the machine. In addition, when the lid body 9 changes from an opened state to a closed state, as shown in FIG. 2, the lock 35 provided on the lid body 9 engages with the lid lock hole 36 provided on the main body 1, and is in operation It will be electrically locked, and the cover 9 will not be opened.

As shown in FIG. 2, when an external force of F1 is applied to the lid 9 downward 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 connecting member 21 and the lower connecting member 22 is insufficient, the upper connecting member 21 and the lower connecting member 22 will be deformed and cause The position of the cover 9 is shifted. Thereby, when the cover 9 is closed, the water seal between the cover 9 and the window packing 34 will be broken. As a result, the washing liquid in the water tank 2 may leak to the outside of the machine, or the position of the lock 35 relative to the lid lock hole 36 when the lid 9 is closed may be difficult to close the lid 9.

For example, in the cover body with a circular shape as in the past example, even if it is desired to arrange the connecting members away from each other, it is impossible to keep the connecting members away from the center line of the cover body. Therefore, in order to increase the strength of the connecting portion of the cover, the thickness of the connecting member is increased, or a reinforcing material is provided, which requires considerable cost.

However, in this embodiment, by making the cover 9 into a quadrangular shape (including a substantially quadrangular shape), the two upper connecting members 21 and the lower connecting members 22 can be arranged sufficiently apart from each other. Thereby, as shown in FIG. 2, when an external force F1 is applied to the cover 9, the force acting on the upper connecting member 21 and the lower connecting member 22 can be reduced.

Furthermore, the upper connecting member 21 has a curved shape. Although there is a concern that the external force F1 will be weaker with respect to the downward direction, the lower connecting member 22 can support the cover 9 with sufficient strength relative to the downward load. . Therefore, no special reinforcement measures are required, and the deformation of the upper connecting member 21 and the lower connecting member 22 can be prevented. Thereby, it is possible to prevent the leakage of the washing liquid caused by the positional deviation of the cover 9 and the deterioration of the operability during the closing operation of the cover 9 can be prevented.

Furthermore, as shown in FIG. 2, it is conceivable that a force outside F2 is applied to the lid 9 in the open chase direction while the lid 9 is opened. When the cover 9 is fully opened, the brake pad 37 provided on the upper bearing member 27 abuts the setting The protruding part 38 of the upper connecting member 21 is provided with a stopper in the chase opening direction (refer to FIG. 14). Therefore, when the load of F2 is applied to the cover 9 in the chase opening direction, the direction of the force acting on the upper arm portion 23 will be the left direction of the body 1 in FIG. 14, that is, the direction in which the upper bearing member 27 is not easily deformed. Therefore, there is no need to increase the thickness of the upper connecting member 21 and the lower connecting member 22, or to provide a special structure such as a reinforcing member to increase the cost, and the connecting structure of the strong cover 9 can be realized relatively simply.

Furthermore, although not shown in the figure, the lower connecting member 22 may be provided with a stopper in the chase-opening direction similarly to the upper connecting member 21. Thereby, the force acting on the upper connecting member 21 and the lower connecting member 22 is divided into two, so that the lower bearing member 28 is not easily deformed.

(Explanation of the front shape of the drum-type washing machine)

As shown in FIG. 1, the cover 9 has a quadrangular shape (including a substantially quadrangular shape), and the horizontal width dimension W1 is equal to the horizontal width dimension W2 of the main body 1 (including approximately equal). In addition, the width dimension of the lower panel 40 covering the drain filter 79 (refer to FIG. 29) stored in the lower part of the main body 1 is equal to (including approximately equal) the width dimension W2 of the main body 1. Thereby, when viewed from the front of the product, the front surface of the drum-type washing machine becomes a flat shape. In addition, although the dividing gap 41 between the cover 9 and the lower panel 40 can be seen from the front of the drum-type washing machine, the cover 9 only rotates in the horizontal direction, so the dividing gap 41 can be controlled within 5 mm without being noticeable. Furthermore, the lower part of the lower panel 40 is configured such that the user's feet can be inserted under the lower panel 40 by not arranging parts and recessing to the front frame 5 of the main body 1 side. In this way, when the laundry is taken out and put in, the user can stand closer to the Body 1 position to work.

Moreover, as shown in FIG. 1, it is comprised so that the upper surface of the main body 1 and the upper surface of the cover 9 may be the same surface (including substantially the same surface). Thereby, the top surface of the product becomes a flat shape, which can improve the design.

For example, in the case of a circular lid as in the conventional example, in order to prevent interference between the lid and the main body when the lid is closed, it is necessary to widen the gap between the periphery of the lid and the main body to a certain extent, and The surface of the cover is made into a shape protruding from the body. The interference between the cover and the body is the largest at the intersection of the switch fulcrum of the cover and the outer periphery of the cover. Once the interference is to be avoided, the gap or drop between the cover and the main body will increase, and it becomes difficult to design the cover and the main body into the same type.

In this embodiment, the lateral width W1 of the cover 9 is equal to the lateral width W2 of the main body 1 (including approximately equal), so that the front frame 5 of the main body 1 is covered by the cover 9. Thereby, the division between the periphery of the cover 9 and the main body 1 disappears, the front surface of the product can be made flat and the division gap can be reduced, and the design can be improved.

In addition, as shown in FIG. 2, in a state where the lid body 9 is opened, the upper connecting member 21 extends forward from the front frame body 5 and therefore becomes exposed. On the other hand, the lower connecting member 22 is hidden in the lower edge 32 of the cover 9 and hardly exposed (refer to FIG. 9). Therefore, even in the state where the cover 9 is opened, it will have a simple appearance, which can improve the design. When the laundry is taken out from the opening 6 and put in, it is conceivable that the sagging part of the laundry will contact the vicinity of the lower connecting member 22. In this embodiment, since the lower connecting member 22 is covered by the cover 9, it is possible to prevent the laundry from being hooked by the lower connecting member 22. Also, preventable The lower connecting member 22 is prevented from contacting the water dripped from the laundry, and the lower connecting member 22 can be prevented from being wetted and corroded by the washing liquid of the laundry.

(Describe the assembly of the body 1 for the cover 9)

FIG. 5 is a perspective view showing the connecting member 21 in a state where the cover 9 is removed. FIG. 6 is a perspective view showing the connecting member 22 in a state where the cover 9 is removed.

As shown in FIGS. 5 and 6, in a state before the cover 9 is attached to the main body 1, the upper connecting member 21 and the lower connecting member 22 extend forward from the front frame 5. In addition, the upper support shaft portion 24 and the lower support shaft portion 26 extend upward by approximately 10 mm. Furthermore, as shown in FIG. 7, the lid body 9 is provided with an opening 42 at a position corresponding to the upper connecting member 21 on the back surface of the lid body 9.

When the cover 9 is mounted on the main body 1, after the upper arm portion 23 of the upper connecting member 21 is inserted into the opening 42 of the cover 9, as long as the force is removed, the cover 9 will sag due to its own weight. Thereby, the upper supporting shaft portion 24 is inserted into the upper bearing member 27. In this way, the upper connecting member 21 of the cover 9 is supported from below, and is rotatably attached to the main body 1. In addition, since the lower connecting member 22 supports the lower edge 32 of the cover 9 from below, it is not necessary to insert the opening part. That is, during the operation in which the upper arm portion 23 of the upper connecting member 21 is inserted into the opening portion 42, the lower support shaft portion 26 is also inserted into the lower bearing portion 28. In this way, the installation of the cover 9 to the main body 1 is carried out.

Since the upper support shaft portion 24 and the lower support shaft portion 26 extend upward by only about 10 mm, the distance that the lid 9 moves downward due to its own weight after the upper connecting member 21 is inserted into the opening 42 is only about 10 mm. Therefore, the cover 9 can be attached to the main body 1 as if by a single action, so that assembly can be achieved The improvement of sex.

FIG. 10 is a perspective view showing the peripheral structure of the connecting portion in a state where the cover 43 is removed. Figure 11 is a perspective view of the main body and the lower part of the cover. In the state where the upper bearing member 27 and the lower bearing member 28 have been inserted into the upper support shaft portion 24 and the lower support shaft portion 26, the cover 43 covering the opening portion 42 is attached to the cover 9. The upper surface 44 of the cover 43 is located close to the lower surface 45 of the upper connecting member 21. With this configuration, the 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 falling off 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 cover 9. The lead wire 46 from the main body 1 and the lead wire 47 from the operation display portion 16 are connected in the opening 42 by the connector 48 (refer to FIG. 10). Therefore, the cover 43 also has the function of protecting the lead 46 and the lead 47 waterproofly. The lead 46 and the lead 47 are constructed by bundling a plurality of leads.

The lead wire 46 from the main body 1 is housed in the lead wire cover 49 as shown in FIG. 8. A lead cover 49 is attached to the upper arm portion 23 of the upper connecting member 21 from below the upper connecting member 21 to protect the lead 46 waterproofly.

As shown in FIGS. 7 and 8, the mating surface 49a of the lead cover 49 with the upper arm portion 23 is formed in the same shape as the upper arm portion 23 (including substantially the same shape). The lead wire cover 49 includes a lead wire accommodating portion 49b that accommodates the lead wire 46 from the main body 1 on the side of the mating surface 49a with the upper arm portion 23. The lead wire accommodating portion 49b is provided with a pressing portion 77 which presses the lead wire 46 accommodated in the lead wire accommodating portion 49b. The lead wire 46 is accommodated in the lead wire accommodating part 49b, and the lead wire 46 is pressed by the pressing part 77, and the movement of the lead wire 46 is prevented. In this state, the lead cover 49 will be locked under the upper arm 23 surface.

In the state where the lead wire cover 49 is locked to the lower surface of the upper arm portion 23, there is a gap of approximately 2 mm between the lead wire 46 and the lower surface of the upper arm portion 23. The lead wire 46 pulled out from the lead wire receiving portion 49b will climb around the center axis 24a of the upper support shaft portion 24 inside the opening 42 of the cover 9 (refer to FIG. 7). The lead wire 46 climbing in the opening 42 is locked in the opening 42 by a fixing pin 78 at any position (for example, a position of 100 mm from the front end). The fixing pin 78 is at a position that is a little distance apart from the vicinity of the central axis 24 a of the upper support shaft portion 24 to lock the lead wire 46 in the opening 42. The front end portion of the lead wire 46 fixed by the fixing pin 78 is connected to the lead wire 47 from the operation display portion 16 in the opening 42 by the connector 48. The opening 42 is blocked by the cover 43 being locked to the cover 9.

The pressing portion 77 is configured such that the distance between the pressing portion 77 and the bottom surface of the lead accommodating portion 49b is the same size (including substantially the same size) as the radius of the lead 46. In addition, the pressing portion 77 is arranged in the vicinity of the central axis 24 a of the upper support shaft portion 24. The lead wire cover 49 includes a pull-out portion 99 for drawing the lead wire 46 from the lead wire accommodating portion 49b in the vicinity of the pressing portion 77. The pull-out portion 99 is located near the central axis 24a. Thereby, the lead wire 46 pulled out from the lead wire accommodating portion 49b extends from the bent portion to the range B (refer to FIG. 7) that is locked to the opening 42 by the fixing pin 78, and the lead wire 46 can be connected to the upper pivot The central axis 24a of 24 is easily accessible. In the range B from the bent portion of the lead wire 46 to the fixing pin 78 locked in the opening 42, the lead wire 46 will evolve to not be at right angles (including slightly right angles) with respect to the central axis 24a of the upper support shaft part 24 )'S leading part. With the opening and closing of the cover 9, the stress loaded on the lead wire 46 will change from the concentrated stress in the bending direction, which has a great influence on the wire break, to the stress in the twisting direction. Therefore, the breakage of the lead wire 46 can be reduced. Worry.

The lead wire 46 stored in the section C of the lead cover 49 (refer to FIG. 7) and the section from the section C to the section where the fixing pin 78 is locked to the opening 42 does not have a stress effect even if the cover 9 is opened and closed , Without moving. Therefore, the fear of disconnection of the lead wire 46 due to additional stress can be eliminated. In addition, since it is in a hidden state and not exposed to the outside, it is possible to prevent corrosion and deterioration caused by the adhesion of water or foreign objects that invade from the outside.

In addition, the lead 46 and the lead 47 are formed by bundling a plurality of leads and winding them with tape. In addition, there are cases where a plurality of lead wires 46 and 47 are provided. Since the opening 42 of the lead wire 46 is provided near the upper side surface 65 where there is no window glass 33, there is no need to reduce the window glass 33 for the lead wire 46. Since the window glass 33 is brought into contact with the window gasket 34 (see FIG. 3) attached to the sink 2 so as to cover the opening 6 in a water-sealed manner, neither the window gasket 34 nor the opening 6 needs to be reduced. Therefore, the ease of putting in and taking out the laundry is not impaired.

The upper surface 44 of the cover 43 is close to the lead cover 49 (refer to FIG. 10). In this embodiment, since the cover 43 rotates together with the cover 9, in order not to rub the cover 43 and the lead cover 49 during the opening and closing operations of the cover 9, there is a gap of 2 mm. With the above structure, since the engagement width of the upper shaft portion 24 and the lower shaft portion 26 is approximately 10 mm, even if the cover 9 is lifted upward, the cover 9 can be prevented from being separated from the upper connecting member 21 and the lower connecting member. 22 fell off. On top of this, it is also possible to prevent dirt such as a lotion immersed from the outside from adhering to the lead 46 and the lead 47, thereby corroding and deteriorating the lead 46 and the lead 47.

(Description of the composition of the cover 9)

FIG. 20 is an exploded perspective view of the cover 9. Hereinafter, the structure of the cover 9 will be described in detail based on FIG. 20.

The cover 50 has a quadrangular shape (including a substantially quadrangular shape), and has a circular hole in the center. On the back side of the cover 50, a cover back plate 51 having a quadrangular shape (including a substantially quadrangular shape) similar to that of the cover 50 and having a hole 52 in the center is formed. The cover back plate 51 is a box-shaped frame part having two side walls and a lower wall. A transparent window glass 33 is clamped between the cover back plate 51 and the cover 50 to enter the circular hole 52 of the cover back plate 51. The upper left part and the lower left part of the cover back plate 51 are formed with an upper bearing member 27 and a lower bearing member 28.

On the surface side of the cover 50, a ring-shaped decorative plate 58 is inserted into the hole. With the decorative board 58, a mortar-shaped slope 59 is formed on the surface side of the cover 50. In addition, a transparent window cover 60 having a square shape (including a substantially square shape) is provided on the surface side of the cover 50. The window cover 60 is provided with a plurality of engaging holes 60c on both side surfaces 60a (refer to FIG. 22). The engaging claw 51a formed on the side wall of the cover back plate 51 engages with the engaging hole 60c to temporarily fix the window cover 60.

Steps 60b are provided on both side surfaces 60a of the window cover 60 on the front side (refer to FIG. 23). On both side surfaces of the cover body 9, window frame members 73 and 76 are installed to cover the cover back plate 51 and the side surface 60a of the window cover 60 and slide from above to below. The step portion 60b of the window cover 60 is covered by the window frame members 73 and 76. Since the fixed portion of the window cover 60 is covered and hidden by the window frame members 73 and 76, the window cover 60 becomes a shape that constitutes the entire front surface of the cover body 9. Thereby, the front surface of the cover 9 becomes a flat shape, and the design can be improved.

The front surface of the window cover 60 becomes a completely flat shape. Window cover 60 As shown in FIG. 19B, the back surface of the decorative plate 58 abuts against the outer edge 61 of the decorative plate 58 in the front-rear direction. The inner edge 62 of the decorative board 58 covers the vicinity of the clamping portion 63 of the transparent window glass 33. The outer edge 61 and the inner edge 62 of the decorative board 58 are continuous by a mortar-shaped inclined surface 59.

A decorative plate 58 having a slightly circular ring shape is provided between the back surface of the window cover 60 and the window glass 33. On the back surface of the window cover 60, a cylindrical (including a substantially cylindrical shape) protrusion 88 (see FIG. 19B) is provided so as to approach the outer edge 61 of the decorative panel 58. The area larger than the diameter of the ridges 88 on the back of the window cover 60 constitutes an opaque coating area 64, and the part surrounded by the ridges 88 becomes a highly transparent area 82 (see FIGS. 19A and 19B ). In addition, the decorative plate 58 is painted or electroplated in a color different from the painting range 64 of the window cover 60, and becomes an appearance color that can be seen through the transparent window cover 60.

In this embodiment, the main body 1 is made white, the painting color of the painting area 64 on the back of the window cover 60 is made the same white as that of the main body 1, and the decorative plate 58 is electroplated. Thereby, the periphery of the transparent window glass 33 can look like it is surrounded by the ring-shaped electroplated decorative plate 58, and an impressive appearance can be constructed in design. Furthermore, if the decorative board 58 is configured with another painting color, the type of model can be easily expanded.

In addition, since the cover 50 is an invisible part and does not need to be painted, it can be molded with a resin that is relatively inexpensive and does not have to worry about being invaded by liquid lotion or the like. Furthermore, when painting, in order to ensure the adhesion of the painting, expensive ABS resin must be used for the material. When ABS resin is used, in order to prevent it from deteriorating even if chemicals such as liquid lotion are attached, it is necessary to add drug-resistant ingredients to blend, making the price more expensive.

For example, when tap water, lotion, or the like is splashed on the lid body 9, water may intrude into the lid body 9 from a fitting gap with the operation display portion 16 fitted on the upper part of the lid body 9. In this embodiment, since the ridge 88 is arranged close to the outer edge 61 of the decorative plate 58, even if the water reaches the outer circumference of the ridge 88, it is possible to prevent water from entering the highly transparent area 82 surrounded by the ridge 88. Furthermore, it is possible to prevent water from reaching the front side of the mortar-shaped slope 59. Since water is immersed in the area 82 with high transparency, the appearance of dirt will damage the quality, so it can be designed to have high resistance to the appearance of dirt.

In addition, the protruding strip 88 on the back of the window cover 60 also has an effect of facilitating the masking operation at the time of painting. Generally speaking, if there is an area that cannot be painted, it must be shielded to prevent the intrusion of paint. However, in this case, the shielding operation is difficult and the yield is deteriorated. Here, if a masking jig (JIG) (not shown in the figure) abuts the protruding strip 88, it is possible to reliably perform masking with a small area, thereby improving the workability of painting.

(Description of the grip)

FIG. 24 is a plan view for explaining the grip, the connecting rod, and the lock, and shows a state where the grip 55, the connecting rod 57, and the lock 35 are assembled to the cover back plate 51. Furthermore, the cover 50 is not shown. The lock 35 is arranged near the center line of the hole 52 to ensure water tightness. The grip 55 is arranged at the upper right end of the cover 9. In this way, by raising the position of the grip 55, the user does not need to bend down when opening the lid body 9. Therefore, the operability of opening and closing the lid 9 can be improved.

Since the grip 55 is arranged on the upper part of the cover 9, the grip 55 and The lock 35 will be placed away from each other. Therefore, between the grip 55 and the buckle 35, a connecting rod 57 is provided therein. The grip 55 rotates toward the front side of the cover 9, and the rotation of the grip 55 is transmitted to the lock buckle 35 via the connecting rod 57. Then, the lock 35 rotates toward the inner side in the width direction of the cover 9. By the rotation of the lock buckle 35, the engagement between the lock buckle 35 and the main body 1 will be released, and the cover body 9 will be in a rotatable state. The connecting rod 57 is composed of a high-rigidity high-steel wire material, and is maintained in a freely rotatable state by the bearing portions 80 and 81 formed on the cover back plate 51. In addition, the step portion 97 provided at one end of the connecting rod 57 abuts the grip 55, and the step 98 provided at the other end of the connecting rod 57 abuts the buckle 35.

25 is a perspective view of the main parts of the cover, and shows the installation state of the grip 55 and the connecting rod 57. Fig. 26 is a perspective view of the main parts of the cover and shows the installation state of the lock 35.

In the vicinity of the center line of the right side of the hole 52 of the cover back plate 51, a lock 35 that can rotate freely through a lock shaft 53a (refer to FIG. 7) is installed. A lock spring 54 that pushes the lock 35 is provided. The lock catch 35 is pressed by the lock catch spring 54 such that the engaging claw of the lock catch 35 rotates outward in the width direction of the cover 9.

In addition, a rotatable grip 55 is attached to the back side of the upper right side of the cover back plate 51. The grip 55 is pushed down by the grip spring 56 with a weak pushing force (refer to FIG. 20). The connecting rod 57 is rotatably attached to the cover back plate 51. One end of the connecting rod 57 provided with a bent portion abuts against the buckle 35, and the other end abuts against the handle 55, and the connecting rod 57 has a means for transmitting the rotation of the handle 55 to the buckle 35 function. That is, when the user opens the cover 9 with the cover 9 closed, he only needs to pull the handle 55 to the side of the cover 9, and The engaging claw of the lock 35 engaged with the cover lock hole 36 provided on the side of the main body 1 rotates toward the inner width direction of the cover 9 to release the engaged state and open. Thereby, the lid body 9 is formed in an openable state. In addition, the lock 35 and the grip 55 are also shown in FIG. 2 when viewed from the side of the cover back plate 51 that is the back surface of the cover body 9.

When the user pulls the handle 55 toward the front side of the lid 9 in order to open the lid 9, the handle 55 will rotate in the front direction of the lid 9 with the shaft portion 84 as the center, and press as the connecting rod 57.接部的步部97。 Join the step portion 97. As a result, the connecting rod 57 rotates around the bearing parts 80 and 81 and presses the lock catch 35 with the step part 98. As shown in Figure 26, the lock 35 uses the shaft 85 as the center to resist the urging force of the lock spring 54 to rotate the engaging claw of the lock 35 in the direction of the body 1 of the cover 9 to release the lock hole from the cover. 36 card fits. Thereby, the lid body 9 becomes an openable state.

In order to make the lid 9 easy to open, the rotation of the handle 55 must be transmitted to the lock 35 without loss. When the handle 55 and the lock 35 are arranged at a distance apart, the connecting rod 57 connecting the handle 55 and the lock 35 will become longer, so the connecting rod 57 will be prone to torsion deformation, etc., and the operation of the connecting rod 57 will be worse. Yu.

In this embodiment, the connecting rod 57 is made of, for example, a high-steel wire used in a spring or the like, so that even if it has a small diameter (for example, a diameter of 3.2 mm), sufficient rigidity can be obtained. In addition, since the shape of the connecting rod 57 can also be made into a simple shape in which the step portions 97 and 98 are provided at both ends, it can be easily processed and manufactured at low cost.

In order to rotate the lock 35 until the lid 9 is in an openable state, the rotation angle θ of the connecting rod 57 must be approximately, for example, θ=20°. When the torque T=220Nmm generated by the pressing force of the lock spring 54 acts, the connecting rod The torsion angle ψ of 57 can be derived from the formula ψ=TxL/(GcIP).

In this embodiment, the length L of the rotating part of the connecting rod 57 is set to L=242mm; the material of the connecting rod 57, that is, the transverse elastic coefficient G of the high-steel wire is set to G=78500N/mm ² ; the section of the connecting rod 57 is extremely inertial The polar moment of inertia of area IP is set to IP=10.3mm ⁴ . At this time, the torsion angle ψ of the connecting rod 57 can be approximated to about ψ=3.7° by the above formula, and the rotation angle of the grip 55 can be set by estimating the deformed portion.

In this way, if the torsion angle ψ of the connecting rod 57 is limited to a range of about 20% of the normal rotation angle θ, the movement of the grip 55 can be reduced, and therefore the thickness of the cover 9 in the front and rear directions can be thinned. The thinned part of the cover 9 can be used flexibly as the effective space of the main body 1.

In addition, since the cover back plate 51 is a resin molded product, warpage due to molding occurs. However, the connecting rod 57 has a slender shape. Even if a warpage of about 2 mm occurs relative to the height of 240 mm of the cover back plate 51, the connecting rod 57 is easily deformed in the longitudinal direction and is easy to adapt. The turning action forms an obstacle.

(The description of the main body of the grip 55)

FIG. 27 is a perspective view of the upper part of the main body and the cover, and shows the surrounding structure of the grip 55 in a state where the cover 9 is closed. FIG. 28 is a diagram showing a longitudinal section of the peripheral structure of the grip, and shows the peripheral structure of the grip 55 in a state where the lid 9 is closed.

The grip 55 is provided on the back side of the upper part of the cover 9. A recess 86 is provided at a position opposite to the grip 55 on the upper front surface of the main body 1.

When the cover 9 is closed, the grip 55 becomes No, and only a little bit can be seen from above. Thereby, the presence of the grip 55 can be suppressed in appearance. When the user wants to open the cover 9 and put his hand on the grip 55, the recess 86 provided on the upper surface of the main body 1 ensures sufficient space for inserting the hand. Therefore, the convenience of the user will not be impaired. The recess 86 is also invisible from the front, and can be a flat design in appearance. In addition, when viewed from above, since the recessed portion 86 can be clearly visually confirmed, when the lid 9 is opened, the user can recognize the position of the grip 55.

(Description of the structure of the operation display)

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. In this space, as shown in FIG. 17, an operation display unit 16 is fitted from above the cover 9. The operation display unit 16 is equipped with: for example, the user selects from above the input mechanism for the operation course from the standard washing to the "standard course" of washing and dewatering, or the "strengthening course" for washing stubbornly dirty clothes. Part, and a display part that is a display mechanism that makes an LED (light emitting diode) emit light to display the operating state in a manner that can be seen from above.

As shown in FIG. 19B, on the upper surface of the cover body 9, an operation display panel 67 for arranging and printing operation parts or display parts is arranged. As shown in FIG. 19B, on the back side of the operation display panel 67, an operation display substrate 68 equipped with a touch switch (tact switch/ALPS registered trademark; general name is tactile switch), LED, and electronic circuit, etc. is concluded. Between the operation display board 67 and the operation display board 68, there is an intermediate member 69 which transmits the operation performed by the user from the surface to the touch switch or guides the light emission of the LED to the surface side. Proceed like this, The operation display unit 16 shown in FIG. 15 is constituted.

For example, when the cover body is formed into a circular shape as in the conventional example, as shown in FIG. 34, the operation display unit 500 is generally arranged at the upper front part of the main body 100 in consideration of the user's operability and visibility.

However, as in the present embodiment, when the cover 9 has a quadrangular shape (including the scraped quadrangular shape), and the horizontal width is equal to (including slightly equal) the horizontal width of the main body 1, the operation can be The display portion 16 is arranged at any position of the upper part of the front surface of the cover 9, the upper surface 66 of the cover 9, and the front part of the top surface of the main body 1.

For example, if the operation display unit 16 is arranged on the upper part of the front face of the lid body 9, a plurality of displays related to operation and display will appear on the front of the product. In this structure, it is difficult to make the front surface of the lid body 9 into a completely flat shape. In addition, it becomes difficult to make a simple structure by minimizing the mating parts visible from the front.

In addition, when it is assumed that the operation display portion 16 is arranged on the top front portion of the main body 1, the operation display portion 16 will be retracted from the front surface of the product by a distance of about the thickness of the cover 9 to allow the user to operate or read the display The convenience becomes worse. That is, the ease of use deteriorates.

Therefore, in this embodiment, the operation display portion 16 is arranged on the upper surface 66 of the cover 9. With this configuration, the front surface of the cover 9 has a completely flat shape, and the fitting portion visible from the front can also be used only as the partition gap 41 with the lower panel 40, and a simple appearance can be realized. In recent years, the front-loading washing machine has also been placed in line with the washstand. When not in use, it can also create a design space that is compatible with other equipment. expected. In this embodiment, the concise appearance of the above-mentioned structure can be used to harmonize the installation space. In addition, when the user operates the operation display unit 16, the operation display unit 16 is arranged closest to the front and can be visually confirmed and operated from above with a natural line of sight. Therefore, the ease of use can also be improved.

Furthermore, by disposing the operation display part 16 on the cover 9, the operation display part can be eliminated from the upper part of the main body 1, and the height (size) of the operation display part can be increased and the water tank 2 can be arranged above. By arranging the water tank 2 above, the workability of taking out and putting the laundry into the rotating drum 3 can be improved.

Furthermore, in this configuration, there is a need to connect the cover 9 provided with the operation display portion 16 and the main body 1 provided with electronic components such as the motor 11 by the leads 46 and 47. In this embodiment, as shown in FIGS. 7 and 10, the opening 42 on the back of the cover 9 is connected with the lead wire 47 from the operation display unit 16 and the lead wire 46 from the main body 1 by a connector 48. With this structure, assemblability is improved. In addition, since the lead wire is covered with the cover 43 and the lead wire cover 49 in a waterproof manner, it is possible to prevent deterioration of the lead wire due to the penetration of the lotion liquid.

As shown in FIG. 15, a plurality of locking portions 70 are provided under the operation display portion 16. Furthermore, as shown in FIG. 16, a locking portion 71 is provided on the cover back plate 51 corresponding to the position of the locking portion 70. Furthermore, as shown in FIG. 18, the cover 50 is provided with a locking portion 72. Furthermore, FIG. 18 is a perspective view of the main parts of the state where the window cover 60 is removed. FIG. 17 is a perspective view of the main part of the state where the operation display portion 16 is inserted into the cover from above. In FIG. 17, the plurality of locking portions 70, 71, 72 are located at positions where they cannot be locked with each other, and the operation display portion 16 is located at a position where it cannot move downward. When the operation display part 16 moves from this position to the left direction (c side When moving to), the locking portion 70 and the locking portion 71, and the locking portion 70 and the locking portion 72 will be in a locked state, and the operation display portion 16 will fall at a predetermined position. Then, the window frame member 73 is inserted into the right side wall of the cover 9 from above. The window frame member 73 restricts the rightward movement of the operation display portion 16 to prevent the locking portion 70, the locking portion 71, and the locking portion 72 from falling off.

18 is a perspective view of a main part of a state where the locking portion 70 and the locking portion 72 are locked, and the window frame member 73 is attached to the right side wall of the cover 9. The movement of the operation display unit 16 in the left direction is restricted by the locking portion 70, the locking portion 71, and the locking portion 72. The right movement of the operation display unit 16 is restricted by the window frame member 73. Since the locking width of the locking portions 70, 71, 72 is only about 5mm, it is sufficient to insert the operation display portion 16 from above, and the amount of movement in the left direction is only about 5mm, so that the operation display portion 16 The assemblability of the cover 9 is improved.

Furthermore, by providing a plurality of locking portions 70, 71, 72, the operation display portion 16 is surely held at a predetermined position where it will no longer move downward to prevent it from floating upward. When the operation display portion 16 floats upward, the fitting gap 74 between the operation display portion 16 and the cover back plate 51 or the fitting gap 75 between the operation display portion 16 and the window cover 60 as shown in FIG. 19B increases. If the mating gaps 74 and 75 become larger, not only will the appearance quality be impaired, liquid lotion or dirt will intrude into the cover 9 from the mating gaps 74, 75, and there will be problems such as malfunctioning of the operation display substrate 68. The fear. Therefore, by arranging a plurality of locking portions 70, 71, 72 at intervals of about 100 mm, for example, which can sufficiently suppress floating across the entire area, the fitting gaps 74, 75 can be suppressed across the entire area. Very small. In this way, it can provide very superior design and Reliable operation display unit 16. Furthermore, a window frame member 73 may also be provided on the left side wall of the cover body 9, and the color of the body 1 may be changed by painting or the like to give a striking and impressive structure in design.

The horizontal width of the operation display portion 16 is the same as the horizontal width W1 of the cover 9 (including slightly the same), and a relatively large space can be obtained. On the other hand, as for the size of the vertical width W3, as shown in FIG. 15, only the thickness of the cover 9 can be obtained. In addition, the thickness of the cover 9 may be restricted to a small size in order to ensure the space on the main body 1 side. In addition, in order to make it easier to read the display arrangement corresponding to a plurality of operation strokes or the washing time of a selection button, the operation display unit 16 needs a certain thickness. The above-mentioned plural locking parts 70, 71, 72 can hold the operation display part 16 in a more space-saving manner compared to the general bolting. Since the operation display portion 16 can be enlarged by saving the space of the structural member, it is possible to realize a configuration that is easier to read. In addition, even if bolting is not performed, the window frame member 73 can prevent the operation display portion 16 from falling off the cover body 9, so that the fitting gap with the cover body 9 can be kept small.

The front frame 5 of the main body 1 supports a lower panel 40 at a position below the cover 9 and makes it rotatable. Body 1 front frame A drain filter 79 for filtering the drain from the water tank 2 is arranged at the lower part of 5. The lower panel 40 covers the drainage filter 79. The lower panel 40 has a width dimension equal to (including approximately equal to) the width dimension W2 of the main body 1.

As shown in FIG. 30, a left shaft 89 is formed on the lower left portion of the lower panel 40 facing the side of the lower panel 40. The left shaft portion 89 has a non-circular shape and contains a baffle device (not shown in the figure). Adjacent to the left shaft portion 89, an L-shaped claw portion 90 whose tip is bent toward the left shaft portion 89 is arranged. In addition, at a position facing the claw portion 90 with respect to the left shaft portion 89, an inclined rib 91 that gradually decreases as it becomes the side surface of the lower panel 40 is arranged.

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. An inclined surface 93 that gradually protrudes forward as it becomes the outside is formed on the side surface of the left bearing portion 92. In addition, a restriction rib 94 is protrudingly arranged on the 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 arranged at the lower right portion of the lower panel 40. In the front frame 5 of the main body 1, a right bearing portion 96 into which the right shaft portion 95 is inserted is arranged.

The left shaft portion 89 and the right shaft portion 95 of the lower panel 40 are respectively inserted into the left bearing portion 92 and the right bearing portion 96, and the lower panel 40 slides to the left in FIGS. 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, crosses the inclined surface 93, and is locked to the outer end surface of the left bearing portion 92. The claw portion 90 is locked to the outer end surface of the left bearing portion 92, thereby preventing the lower panel 40 from moving in the detachable and detached direction.

The drainage filter 79 is exposed by the rotation of the lower panel 40. and, By attaching and detaching the drain filter 79, thread and the like attached to the drain filter 79 can be removed.

The lower panel 40 contains a baffle device in the left shaft portion 89. Thereby, when the lower panel 40 rotates, the baffle device functions to apply resistance to the rotation of the left shaft portion 89, thereby slowing the opening and closing speed. By reducing the opening and closing speed of the lower panel 40, the damage of the lower panel 40 can be prevented, and the lower panel 40 can be opened and closed safely.

When the lower panel 40 is in the open state, the claw portion 90 abuts the restriction rib 94 to restrict the rotation of the lower panel 40. In this state, the inclined rib 91 abuts the left bearing portion 92. In the state where the rotation of the lower panel 40 is restricted, when a force is further applied in the direction to rotate the lower panel 40, since the inclined rib 91 abuts against the left bearing portion 89, the lower panel 40 is formed by the inclined rib 91 Move to the right in Figure 32. Although the pawl portion 90 is locked to the outer end surface of the left bearing portion 92, as shown in FIG. 33, as the lower panel 40 moves, the pawl portion 90 bends and deforms so as to fall off from the outer end surface of the left bearing portion 92. When the lower panel 40 rotates further, the claw portion 90 is deformed and falls off from the outer end surface of the left bearing portion 83. As a result, the lower panel 40 can be removed from the main body 1.

As described above, in the present embodiment, when the lower panel 40 is opened, when a force is applied in the opening direction of the lower panel 40, the lower panel 40 is removed from the main body 1 without being damaged. Therefore, even if an excessive load is applied due to misuse, damage to the lower panel 40 can be prevented, and it can be installed again.

Furthermore, in this embodiment, although the cover 9 has a square shape, But it is not limited to this. For example, the cover 9 may have a part formed as a notch, or a part of the cover body 9 may be formed in a bulged shape.

Moreover, although the operation display part 16 is arrange|positioned on the upper surface of the cover 9, it is not limited to this. For example, the operation display unit 16 may be arranged on the upper part of the front surface of the cover 9.

In addition, in this embodiment, although the drainage filter 79 for filtering the drainage from the water tank 2 is arranged at the lower part of the front frame 5 of the main body 1, and the drainage filter 79 is covered with the lower panel 40, it is not Limited to this. For example, it may also be a structure in which other component parts such as a control circuit are arranged at the lower part of the front frame body 5 of the main body 1, and the component parts are covered with a lower panel. Furthermore, in this case, according to the component parts covered by the lower panel, the lower panel can also be made not easy to open.
