Description

  The present invention relates to a drum-type washing machine that performs washing, rinsing, and dewatering steps.

  Conventionally, in this type of drum-type washing machine, as shown in FIG. 23, a circular opening 215 is provided on the front surface of the main body 100, and a lid 300 that covers the opening 215 so as to be freely opened and closed is provided. . The lid 300 is formed in a circular shape that matches the shape of the opening 215 (see, for example, Patent Document 1).

  However, in the conventional technique described above, since the lid is circular, it is necessary to provide a support member that supports the lid to a certain extent in the center side of the end of the lid. For this reason, when the lid is opened and closed, in order to prevent the end of the lid from interfering with the main body, the gap between the periphery of the lid and the main body is widened to a certain extent, and the surface of the lid is protruded from the main body. There is a need to form. Therefore, there is a problem that it is difficult to make the front surface of the product clear and to enhance the sense of quality by designing the lid and the main body in the same form.

  Therefore, by forming a lid body that covers the opening on the front side of the main body so as to have a width dimension substantially equal to the width dimension of the main body, the front surface of the product is made clear, and a high-class design is enhanced. It is possible to do.

  However, when the width of the lid is designed to be substantially equal to the width of the main body, the window glass is disposed on the inner surface side of the lid, and the window glass protrudes toward the rotating drum. However, since the window glass is heavy, it is assumed that the upper side of the lid body moves to the main body side due to the weight of the window glass, and the lower side of the lid body is displaced to the front side.

  In particular, on the connecting part side that supports the lid body, since the lid body is firmly supported by the body, displacement of the lid body with respect to the main body hardly occurs, but the handle side for opening and closing the lid body is Because it is on the free end side of the lid, the lid is easily displaced with respect to the main body, and when viewed from above, the gap between the lid and the main body is different on the connecting side and the handle side, and the design is impaired. It is assumed that

  The present invention solves the above-described conventional problems, and an object of the present invention is to provide a drum type washing machine excellent in design.

In order to solve the above-described conventional problems, the drum type washing machine of the present invention is rotatably provided by a main body having an opening formed in the front and a connecting portion provided on one side of the main body, A lid that closes the opening so as to be openable and closable, and the lid is formed such that a lateral dimension is substantially equal to a lateral dimension of the main body, and the lid is formed on the other side of the lid. A handle that opens and closes is formed, and a biasing means that biases the upper part of the lid side surface of the lid toward the direction away from the main body is formed.

  With such a configuration, it is possible to provide a drum type washing machine excellent in design.

  As described above, according to the present invention, it is possible to provide a drum type washing machine excellent in design.

(Description of connecting portion between main body 1 and lid 9)
The configuration of the connecting portion that rotatably supports the lid 9 on the front frame 5 of the main body 1 will be described in detail below with reference to FIGS.

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

  As shown in FIG. 6, the upper connecting member 21 has an upper arm portion 23 extending forward of the main body 1. In the vicinity of the tip of the upper arm portion 23, an upper support shaft portion 24 extending above the main body 1 is provided. As shown in FIG. 7, the lower connecting member 22 similarly has a lower arm portion 25 extending forward of the main body 1, and a lower support shaft extending upward of the main body 1 near the tip of the lower arm portion 25. A portion 26 is provided.

  As shown in FIG. 1, the lid body 9 has a substantially square shape, and the lateral width dimension W <b> 1 of the lid body 9 is substantially equal to the lateral width dimension W <b> 2 of the main body 1. Thus, both side surfaces of the lid body 9 are formed so as to be substantially flush with the both side surfaces of the main body 1.

  As shown in FIG. 13, the upper support shaft portion 24 is inserted into the 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 the state where the lid body 9 is omitted.

  As shown in FIG. 12, the lower support shaft portion 26 is inserted into the lower bearing member 28 fastened to the lower portion of the lid body 9. As described above, the lid body 9 includes the two upper connecting members 21 and the lower connecting members 22 provided at the positions where the two bearing members 27 and 28 provided on the upper and lower sides of the lid 9 are separated from each other. While being supported from below, it rotates with respect to the main body 1 to cover the opening 6 in a freely rotatable manner.

  14 is a cross-sectional view showing the upper connecting member 21 portion when the lid body 9 is closed, and FIG. 15 is a cross-sectional view showing the upper connecting member 21 portion when the lid body 9 is opened.

  The upper arm portion 23 is formed in a curved shape so that the tip of the side wall 29 of the lid body 9 does not come into contact with the lid body 9 in an open state. Further, a front-rear direction gap (shown by a in FIG. 14) with the front frame 5 when the lid body 9 is closed, and a front end portion of the lid body 9 in a rotation locus from the open state to the closed state of the lid body 9 In order to suppress the protrusion in the width direction from the side surface of the lid body 9 (indicated by b in FIG. 14), the upper support shaft portion 24 is disposed inside the lid body 9, It is disposed near the side wall 29. The front-rear direction gap a is an external appearance gap when viewed from an oblique direction. With the above configuration, the front-rear direction gap a can be reduced, and the design can be improved. In addition, the above-described configuration has an advantage that the allowance b in the width direction can be reduced, can be installed close to the wall of the house when the product is installed, and can be installed in a narrow place.

  On the other hand, as shown in FIG. 7, the lower arm portion 25 of the lower connecting member 22 extends forward of the main body 1 without taking a curved shape like the upper arm portion 23. This is because, as shown in FIG. 10, the lower connecting member 22 supports the lower side 32 of the lid body 9 from below, so that it is not necessary to escape the rotation locus of the side wall 29 of the lid body.

  As shown in FIG. 4, when the lid body 9 is closed, the glass window glass 33 provided on the lid body 9 is in water-sealing contact with the window packing 34 attached to the water tank 2, and The washing liquid is prevented from leaking outside the machine. Further, when the lid body 9 is closed from the opened state, as shown in FIG. 2, the latch 35 provided in the lid body 9 is engaged with the lid lock hole 36 provided in the main body 1 and is electrically operated during operation. So that the lid 9 cannot be opened.

As shown in FIG. 2, when an external force F <b> 1 is applied downward to the lid 9 when the lid 9 is opened, the applied load is supported by the upper coupling member 21 and the lower coupling member 22. . Therefore, if the strength of the upper connecting member 21 and the lower connecting member 22 is not sufficient, the upper connecting member 21 and the lower connecting member 22 are deformed and the position of the lid 9 is shifted, and the lid 9 and the window packing are closed when the lid 9 is closed. There is a possibility that the water seal with 34 is broken and the washing liquid in the water tub 2 leaks out of the machine, or when the lid body 9 is closed, the position of the latch 35 is displaced with respect to the lid lock hole 36 and is difficult to close.

  For example, in the case of a circular lid as in the conventional example, even if the connecting members are separated from each other, they cannot be separated from the center line of the lid. Therefore, enormous costs are required to increase the strength of the connecting portion of the lid, such as increasing the thickness of the connecting member or providing a reinforcing material.

  However, in the present embodiment, by forming the lid body 9 in a substantially square shape, the two upper connecting members 21 and the lower connecting member 22 can be arranged separately from each other. Thereby, as shown in FIG. 2, when an external force F <b> 1 is applied to the lid body 9, the force acting on the upper connecting member 21 and the lower connecting member 22 can be reduced.

  The upper connecting member 21 has a curved shape and seems to be weak against the downward external force F1, but is supported by the lower connecting member 22 with sufficient strength against a downward load. Can do. Accordingly, the upper connecting member 21 and the lower connecting member 22 can be prevented from being deformed without requiring a special reinforcing measure, and the washing liquid leaks due to the displacement of the position of the lid 9 or the lid 9. It is possible to prevent adverse effects such as deterioration of operability during the closing operation.

  Moreover, as shown in FIG. 2, the case where the external force of F2 is applied in the follow-up direction further opened to the cover body 9 in the open state of the cover body 9 is assumed. When the lid 9 is fully opened, as shown in FIG. 15, the stopper piece 37 of the upper bearing member 27 abuts on the protrusion 38 of the upper connecting member 21 to form a stopper in the follow-up direction. When a load of F2 is applied to the lid 9 in the follow-up 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, and the upper bearing member 27 is not easily deformed. Direction. Therefore, the lid 9 can be connected relatively easily and without any cost by adopting a special configuration such as increasing the thickness of the upper connecting member 21 and the lower connecting member 22 or providing a reinforcing member. Can be configured.

  Although not shown, the stopper in the follow-up direction is also formed in the lower connecting member 22 in the same manner as the upper connecting member 21, and the force acting on the upper connecting member 21 and the lower connecting member 22 is divided into two parts. Consideration is given to prevent deformation.

(Description of the front shape of the washing machine)
As shown in FIG. 1, the lid body 9 has a substantially rectangular shape, and the lateral width dimension W <b> 1 is formed to have a lateral width substantially equal to the lateral width dimension W <b> 2 of the main body 1. In addition, a lower panel 40 that covers the drainage filter 79 housed in the lower portion of the main body 1 is formed to have a width that is substantially equal to the width W2 of the main body 1. Thereby, the front shape when viewed from the front of the product can be formed into a flat shape. Moreover, although the division | segmentation clearance gap 41 of the cover body 9 and the lower panel 40 is visible from the product front, since the lid | cover body 9 only rotates in a horizontal direction, the division | segmentation clearance gap 41 can be suppressed within 5 mm, and is not conspicuous. Can be formed. The lower panel 40 is configured so that the user's feet can be inserted below the lower panel 40 by disposing the parts to the main body 1 side up to the front frame 5 of the main body 1 without arranging parts. Yes. Thereby, the user can work while standing in a position closer to the main body 1 when the laundry is taken in and out of the main body 1.

  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 body 9 may become a substantially identical surface. Thereby, the upper surface of a product can be formed in a flat shape, and design property can be improved.

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 opened and closed, the gap between the lid and the main body is widened to some extent, and the lid It is necessary to form the surface in a shape protruding from the main body. Interference between the lid and the main body is greatest at the intersection of the lid opening / closing fulcrum and the lid outer periphery. If it is going to avoid interference, the clearance gap and level | step difference of a cover body and a main body will become large, and it will become difficult to comprise a cover body in the same form as a main body in design.

  The lid body 9 of the present embodiment has a lateral width dimension W1 substantially equal to the lateral width dimension W2 of the main body 1 so that the front frame body 5 of the main body 1 is covered by the lid body 9, so that the periphery of the lid body 9 and the main body No division with 1 is possible, the front surface of the product is flat and there are few division gaps, and the design can be improved.

  Further, as shown in FIG. 2, in the state where the lid body 9 is opened, the upper connecting member 21 is exposed because it extends forward from the front frame body 5, but the lower connecting member 22 is shown in FIG. 10. As shown in FIG. 4, it is hidden behind the lower side 32 of the lid 9 and is hardly visible. Therefore, even when the lid 9 is open, it looks neat and the design can be improved. When the laundry is taken in and out of the opening 6, it is assumed that the hanging part of the laundry touches the vicinity of the lower connecting member 22, but the lower connecting member 22 is covered by the lid body 9, The laundry does not get caught on the lower connecting member 22, and the lower connecting member 22 does not come into contact with water dripping from the laundry, so that the laundry can be prevented from getting wet and corroding.

(Explanation of the assembly of the lid body)
FIG. 6 is a perspective view showing the upper connecting member 21 with the lid 9 removed. FIG. 7 is a perspective view showing the lower connecting member 22 with the lid 9 removed.

  As shown in FIGS. 6 and 7, in a state before the lid body 9 is attached to the main body 1, the upper support shaft portion is located at a position where the upper connecting member 21 and the lower connecting member 22 extend forward from the front frame body 5. 24 and the lower support shaft portion 26 extend upward by about 10 mm. Further, as shown in FIG. 8, 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 attaching the lid 9 to the main body 1, after inserting the upper arm 23 of the upper connecting member 21 into the opening 42 of the lid 9, if the force is removed, the lid 9 is lowered downward by its own weight, and the upper support The shaft portion 24 is inserted into the upper bearing member 27 and is rotatably mounted while being supported by the upper connecting member 21 from below. Since the lower connecting member 22 supports the lower side 32 of the lid body 9 from below, the lower connecting member 22 does not need to be inserted into the opening, and in the process of inserting the upper arm portion 23 of the upper connecting member 21 into the opening 42, the lower connecting member 22 The shaft portion 26 is also inserted into the lower bearing member 28, and the lid 9 can be attached to the main body 1.

  Since the upper support shaft portion 24 and the lower support shaft portion 26 only extend upward by about 10 mm, it is also 10 mm that the lid 9 moves downward by its own weight after the upper connecting member 21 is inserted into the opening 42. Less in degree. Therefore, since the attachment can be performed by one operation, the assembling property can be improved.

FIG. 11 is an exploded perspective view with the cover 43 removed. FIG. 12 is a transparent perspective view of the main body and the lower part of the lid.
As shown in FIGS. 8 and 12, the cover 43 covering the opening 42 is attached to the lid body 9 in a state where the upper support shaft portion 24 and the lower support shaft portion 26 are inserted into the upper bearing member 27 and the lower bearing member 28. The upper surface 44 of the attachment and cover 43 is brought close to the lower surface 45 of the upper connecting member 21. With this configuration, the upward movement of the lid body 9 can be restricted, and even when the lid body 9 is lifted upward, it can be prevented from coming off from the upper coupling member 21 and the lower coupling member 22.

As shown in FIG. 1, an operation display unit 16 is provided on the upper side of the lid body 9. The lead wire 46 from the main body 1 and the lead wire 47 from the operation display unit 16 are connected to the opening 4 by the connector 48.
2 are connected. Therefore, the cover 43 also has a function of protecting the lead wire 46 and the lead wire 47 in a waterproof manner. The lead wire 46 and the lead wire 47 are a bundle of a plurality of lead wires.

  The lead wire 46 from the main body 1 is housed in a lead wire cover 49 shown in FIG. 9, and the lead wire cover 49 is attached to the upper arm portion 23 of the upper connecting member 21 from below the upper connecting member 21. Protect it waterproofly.

  As shown in FIGS. 8 and 9, the lead wire cover 49 has a mating surface 49 a with the upper arm portion 23 formed in substantially the same shape as the upper arm portion 23. In the lead wire cover 49, a lead wire storage portion 49 b that stores the lead wire 46 from the main body 1 is formed on the mating surface 49 a side with the upper arm portion 23. The lead wire storage portion 49b is provided with a pressing portion 77 for pressing the lead wire 46 stored in the lead wire storage portion 49b. The lead wire 46 is accommodated in the lead wire accommodating portion 49b, and the lead wire 46 is prevented from moving by being pressed by the pressing portion 77. In this state, the lead wire cover 49 is locked to the lower surface of the upper arm portion 23.

  In a state where the lead wire cover 49 is locked to the lower surface of the upper arm portion 23, a gap of about 2 mm is provided between the lead wire 46 and the lower surface of the upper arm portion 23. The lead wire 46 drawn out from the lead wire storage portion 49b is placed in the vicinity of the central axis 24a of the upper support shaft portion 24 inside the opening portion 42 of the lid body 9, and is placed at an arbitrary position on the front side (for example, The position of the tip 100 mm) is locked in the opening 42 by the fixing pin 78. The fixing pin 78 locks the lead wire 46 in the opening 42 at a position that is slightly spaced from the vicinity of the central axis 24 a of the upper support shaft 24. The leading end portion of the lead wire 46 fixed by the fixing pin 78 is connected in the opening 42 by the lead wire 47 from the operation display unit 16 and the connector 48. The opening 42 is closed by locking the cover 43 to the lid body 9.

  The holding portion 77 is formed such that the distance from the bottom surface of the lead wire storage portion 49 b is substantially the same radius as the radius of the lead wire 46. The pressing portion 77 is formed at a position close to the central axis 24 a of the upper support shaft portion 24. As a result, the lead wire 46 drawn out from the lead wire storage portion 49b is in the range B (shown in FIG. 8) where the lead wire 46 is locked to the opening 42 by the fixing pin 78 from the bent portion. The central axis 24a can be easily brought close to. In a range B where the lead wire 46 is bent and locked in the opening 42 by the fixing pin 78, the lead wire 46 has no routing portion that is substantially perpendicular to the central axis 24a of the upper support shaft portion 24. Since the stress applied to the lead wire 46 by opening and closing the lid body 9 becomes stress in the twist direction from concentrated stress in the bending direction that has a great influence on the disconnection, the concern about the disconnection of the lead wire 46 can be reduced. .

  The section C (shown in FIG. 8) housed in the lead wire cover 49 and the lead wire 46 that is locked to the opening 42 by the fixing pin 78 are not stressed even when the lid body 9 is opened and closed. It does n’t move. Therefore, it is possible to eliminate the fear of disconnection due to stress being applied. Further, since it is concealed from the outside, it is possible to prevent corrosion and deterioration due to adhesion of dirt such as water and foreign matter entering from the outside.

  The lead wire 46 and the lead wire 47 are obtained by bundling a plurality of lead wires and winding a tape. In addition, a plurality of lead wires 46 and lead wires 47 may be provided. Since the opening 42 through which the lead wire 46 is routed is provided in the upper side surface portion 65 where the window glass 33 does not exist, it is not necessary to make the window glass 33 small in order to route the lead wire 46. Since the window glass 33 is in water-sealing contact with the window packing 34 attached to the water tub 2 so as to cover the opening 6, it is not necessary to make the window packing 34 and the opening 6 small, and the laundry is put in and out. The effect on the ease of work is not impaired.

  The upper surface 44 of the cover 43 is brought close to the lead wire cover 49. In the present embodiment, since the cover 43 rotates together with the lid body 9, a gap of about 2 mm is provided so as not to rub against the lead wire cover 49 to which the cover 43 is fixed in the process of opening and closing the lid body 9. ing. With the above configuration, the upper support shaft portion 24 and the lower support shaft portion 26 have an engagement margin of about 10 mm. Therefore, even when the lid body 9 is lifted upward, it is possible to prevent the upper support member 21 and the lower connection member 22 from coming off. At the same time, the lead wire 46 and the lead wire 47 can be prevented from being corroded and deteriorated due to the adhesion of dirt such as detergent entering from the outside.

(Explanation of lid structure)
FIG. 16 is an exploded perspective view of the lid body 9. Based on FIG. 16, the structure of the cover body 9 is explained in full detail below.

  Reference numeral 50 denotes a lid, which is formed in a substantially square shape and has a circular hole in the center. On the back surface side of the lid 50, similarly to the lid 50, a lid backing plate 51 that is formed in a substantially square shape and has a circular center portion and a hole portion 52 is fastened. The lid back plate 51 is a box-shaped frame component having both side walls and a lower wall. A 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 and a lower bearing member 28 are fastened to the upper left portion and the lower left portion of the lid back plate 51.

  A ring-shaped decorative plate 58 is fitted into the hole on the surface side of the lid 50, and a mortar-shaped slope 59 is formed by the decorative plate 58. A substantially rectangular transparent window cover 60 is provided on the surface side of the lid 50. A plurality of engagement holes 60 c are formed on both side surfaces 60 a of the window cover 60, and the engagement holes 60 c are engaged and temporarily fixed to engagement claws 51 a formed on the side wall of the lid back plate 51.

  On both side surfaces 60a of the window cover 60, step portions 60b are formed on the front surface side. Sash members 73 and 76 are mounted on both side surfaces of the lid body 9 by sliding the sash members 73 and 76 downward from above so as to cover the lid back plate 51 and the side surface 60a of the window cover 60. The step portion 60 b of the window cover 60 is covered with sash members 73 and 76, and the fixed portion of the window cover 60 is covered with the sash members 73 and 76 so that the window cover 60 forms the entire front surface of the lid body 9. it can. Thereby, the front surface of the lid body 9 can be formed in a flat shape, and the design can be improved.

  The front surface of the window cover 60 has a completely flat shape. As shown in FIG. 19, the back surface of the window cover 60 contacts 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 sandwiching portion 63 of the transparent window glass 33, and the outer edge 61 and the inner edge 62 of the decorative plate 58 are continuous by a mortar-shaped slope 59.

  A substantially annular decorative plate 58 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 substantially cylindrical protrusion 88 is provided in the vicinity of the outer edge 61 of the decorative plate 58. The range larger in diameter than the protrusion 88 on the back surface of the window cover 60 forms an opaquely painted area 64, and a portion surrounded by the protrusion 88 is a highly transparent area 82. The decorative plate 58 is painted or plated in a color different from the painting range 64 of the window cover 60, and has an appearance color that can be seen through the transparent window cover 60.

  In the present embodiment, for example, if the main body 1 is white, the coating color of the painting range 64 on the back surface of the window cover 60 is the same white as the main body 1, and the decorative plate 58 is plated, the surroundings of the transparent window glass 33 The ring-shaped plated decorative plate 58 appears to surround the frame, and an appearance having a design impact can be configured. Furthermore, if the decorative board 58 is made of a different paint color, the model can be easily developed.

In addition, the lid 50 is a part that cannot be seen from the exterior, and painting is not required. Therefore, the lid 50 can be molded with a resin that is inexpensive and does not need to be affected by liquid detergent. If the structure is to be painted, it is necessary to use an expensive ABS or the like as the material in order to ensure adhesion of the coating. When ABS is used, it is necessary to add a chemical-resistant specification so that it does not deteriorate even if chemicals such as liquid detergent adhere to it, and it is further expensive.

  For example, when tap water or detergent is applied to the lid body 9, there is a possibility that water may enter the inside of the lid body 9 through a fitting gap with the operation display unit 16 fitted on the upper portion of the lid body 9. In the present embodiment, since the ridge 88 is brought close to the outer edge 61 of the decorative plate 58, even if water travels along the outer periphery of the ridge 88, water enters the region 82 having high transparency surrounded by the ridge 88. Can be prevented, and can be prevented from traveling along the front side of the mortar-shaped slope 59. If water or the like enters the region 82 with high transparency, the quality is deteriorated as appearance dirt, so that the design can be strong against appearance dirt.

  Further, the protrusion 88 on the back surface of the window cover 60 has an effect of facilitating the masking work when painting. In general, if there is an area that should not be painted, it is necessary to mask the surrounding area to prevent the paint from entering, but the masking operation is difficult and the yield is poor. Therefore, by bringing a masking jig (not shown) into contact with the ridge 88, masking can be reliably performed in a small area, so that the workability of painting can be improved.
