  However, when the decorative board described in Patent Document 1 is provided, the number of parts and the number of assembling steps are increased, resulting in an increase in product cost. In addition, the transparency of the lid cover is not indispensable outside the range where the laundry through the window of the lid body is visible from the outside. However, if the transparency of the lid cover is broken at the periphery by the decorative plate, the entire opening and closing lid It has been found that the related products shown in FIG. 6 of Patent Document 1 and the related products shown in FIGS.

  The object of the present invention is to make use of transparency up to the outer periphery having a fixing part by elastic engagement with the lid main body of the cover cover, and the fixing part does not look and feel without requiring a special member or assembly man-hours, The object is to provide a drum-type washing machine with a good appearance.

  In order to achieve the above object, a drum-type washing machine according to the present invention is configured such that a rotating drum formed in a bottomed cylindrical shape has a horizontal or horizontal rotation axis direction from an opening front side toward a back side as a bottom. Installed in the water tank so that it is inclined downward, opens the opening / closing lid provided at the front of the washing machine housing, stores the laundry in the rotating drum, and drives the rotating drum with a motor, washing process, rinsing In the drum-type washing machine capable of at least one of a process and a dehydration process, the opening / closing lid includes a lid body having a window through which the laundry is seen from the outside, and a transparent lid cover that is applied to the front surface of the lid body and covers the lid body A plurality of engaging pieces projecting rearward are integrally formed on the back surface of the outer peripheral portion of the lid cover, and the engaging pieces are received by the lid body, and the received engaging pieces are elastically formed by the locking portions. Engage to prevent slipping A locking hole for locking and fixing the lid cover in a state of being applied to the lid body, and at least a surface of the lid cover in a range substantially corresponding to the fixing portion refracts and disperses light from the inside. It is characterized by having a surface shape to be transmitted.

In such a configuration, the opening / closing lid is closed after the laundry is accommodated in the rotating drum, so that the rotating drum is rotated to perform at least one of the washing process, the rinsing process, and the dehydrating process. While preventing leakage of water, splashes of dehydration, etc., the laundry can be observed through the transparent lid cover and window while observing the state of the laundry from the outside. The transparent lid cover is applied to the front surface of the lid body, and the engagement piece protruding rearward of the back surface of the outer peripheral portion is elastically engaged with the locking portion of the locking hole at the corresponding position of the lid body and fixed. In addition, even if at least the range of the cover cover corresponding to the fixed part remains transparent, the surface of the cover cover has a surface shape that refracts and disperses the light from the inside, so that the reflected light from the fixed part is covered with the cover. Refractive and dispersed when passing through the surface to prevent the image of the fixed part from being imaged by the human eye without any special members or assembly man-hours. As a result of irregular reflection such as a fine textured surface called “uneven”, the surface is not transparent, and a concavo-convex pattern that does not reflect the shadow of the fixed part is exhibited.

  In the above, the lid cover further includes a wraparound peripheral wall that wraps around the outer peripheral surface of the lid main body, the engagement piece is integrally formed on an end surface of the wraparound peripheral wall, and the end surface is formed on the outer periphery of the lid main body. A protruding wall that protrudes from the outer periphery of the lid body is formed integrally with a stepped surface that faces the outer periphery of the lid body, and the locking hole is formed so as to penetrate forward and backward in the protruding wall.

  In such a configuration, in addition to the above, since the lid cover wraps around and covers the outer periphery of the lid main body, the outer periphery that is visible from the front oblique side of the washing machine housing or by the line of sight that extends obliquely from the upper front. A uniform transparent wall area can be extended to a wide area including the surroundings.

  In the above, the lid body further comprises a front frame and a back frame that are arranged in the middle so as to form a window, and a transparent window plate sandwiched between the front and back frames, The overhanging wall is provided on a front frame, the lid cover has a surface in which an outer peripheral surface of the wraparound wall is substantially continuous with an outer peripheral surface of the overhanging wall, and the back frame has an outward flange at a front end thereof. The flange is fitted to a front frame, and the flange is fitted to a step inside the rear end of the overhanging wall.

  In such a configuration, in addition to the above, the lid frame further treats the front frame with the lid cover elastically engaged as one member, and achieves a combined coupling with the back frame while sandwiching the window plate. Or, it can be handled as a single member with the window plate sandwiched between the front and back frames, and the lid cover can be elastically engaged with the front frame and fixed, and the lid cover is the outer periphery of the surrounding wall. Since the surface is substantially continuous with the outer peripheral surface of the overhanging wall, the outer surface is simplified to include a wide area and a solid area. In addition, the back frame has an outward flange at the front end and is fitted to the front frame, and this flange fits into the step inside the rear end of the overhanging wall. Since it is located on the inner side from the outer peripheral surface of the frame, it is possible to reduce the feeling of thickness in the range of appearance in the closed state.

It is one of the uneven surfaces, and the prevention of the appearance of the engaging portion by the uneven pattern that does not impair the transparency is realized.

According to the present invention, the state of the laundry is observed from the outside through the transparent lid cover and the window while preventing leakage of washing water, rinsing water, dehydration splashes, etc. to the outside in the state of being closed by the opening / closing lid. However, when this transparent lid cover is fixed to the front surface of the lid body by elastic engagement with the lid body, at least the area corresponding to the locking portion of the lid cover remains transparent. By reflecting and dispersing the reflected light from the engaging portion that is transmitted by the surface shape, the transparency and the transparent feeling are not impaired, and therefore the appearance of the material that is not seen while improving the transparency without narrowing is improved. It is possible, and for that reason, no special members or assembly man-hours are required, and this does not cause an increase in cost. In addition, it is possible to exhibit a design effect by exhibiting an uneven pattern that does not impair transparency due to irregular reflection such as a fine textured surface and does not project the shadow of the locking portion to the outside.

  Hereinafter, a drum type washing machine according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5 for the understanding of the present invention. In addition, the following description is a specific example of this invention, Comprising: The content of description of a claim is not limited.

  As shown in FIG. 2, the drum-type washing machine 1 according to the present embodiment shown in FIGS. 1 and 2 moves the rotating drum 2 formed in a bottomed cylindrical shape from the opening front side to the back side as the bottom. It is installed in the water tank 3 so that the rotation axis direction is horizontal or inclined downward from the horizontal direction, and the opening / closing lid 5 provided at the front part of the washing machine housing 4 is opened to store the laundry in the rotating drum 2. When the rotary drum 2 is driven by the motor 6, at least one of a washing process, a rinsing process, and a dehydrating process can be performed.

  As shown in FIGS. 1 to 3, the opening / closing lid 5 includes a lid body 8 having a window 7 for seeing through the laundry from the outside, and a transparent lid cover 9 applied to the front surface of the lid body 8. ing. As shown in FIGS. 3 and 4, a plurality of engaging pieces 9 a protruding rearward are integrally formed on the rear surface of the outer peripheral portion of the lid cover 9. Correspondingly, the lid body 8 receives the engaging piece 9a as shown in FIG. 3 and elastically engages the received engaging piece 9a with the engaging portion 8a as shown in FIGS. Locking holes 8b are provided to prevent the cover cover 9 from coming off and to lock and fix the cover cover 9 in a state of being applied to the cover body 8. As a result, the lid cover 9 is fixed to the lid main body 8 in a state where the lid cover 9 is applied and covered from the front side. A positioning projection 41 is provided on a part of the lid cover 9 and is fitted into the positioning hole 42 of the lid body 8. The positioning protrusion 41 does not have the only locking hole 8b.

  In such a fixing structure of the lid cover 9, in order to prevent the fixing portion 11 and the positioning projection 41 by the engaging piece 9 a and the locking hole 8 b from appearing without damaging the transparency of the lid cover 9, In the present embodiment, at least the surface 9b of the lid cover 9 in a range substantially corresponding to the fixed portion 11 is shown by a solid line and a virtual line in FIG. It has a surface shape as in the example. In this way, the transparent lid cover 9 is applied to the front surface of the lid body 8, and the engaging piece 9 a protruding rearward of the back surface of the outer peripheral portion is used as the locking portion 8 a of the locking hole 8 b at the corresponding position of the lid body 8. Even if at least the locking hole 8b and the fixing portion 11 of the lid cover 9 are transparent, the surface 9b refracts and disperses light from the inside even when the cover cover 9 is transparent. When the reflected light from the locking portion 8a, the locking hole 8b, the engaging piece 9a, etc. of the fixing portion 11 is transmitted through the surface 9b of the lid cover 9, the solid arrow in FIG. As shown by the phantom line arrow, the surface 9b is refracted and dispersed to prevent the image of the locking portion from being imaged by human eyes without any special members or assembly man-hours. And the transparency is lost due to irregular reflection like a fine textured surface. It exhibits an uneven pattern without that would reflect the shadow.

As a result, the state of the laundry is observed from the outside through the transparent lid cover 9 and the window 7 while preventing washing water, rinsing water, splashes of dehydration, etc. from leaking outside while being closed by the open / close lid 5. However, in order to fix the transparent lid cover 9 to the front surface of the lid body 8 and to fix the lid body 8 by elastic engagement with the lid body 8 at the fixing portion 11, at least the fixing portion 11 of the lid cover 9 is fixed. The corresponding range remains transparent, and the reflected light from the fixed portion 11 that is transmitted by the surface shape of the surface 9b is refracted and dispersed, so that the transparency and transparency are not impaired, and thus the transparent area is not narrowed and enhanced. However, it can be made to have a good texture that is not visible, and therefore, no special members or assembly man-hours are required and this does not cause an increase in cost. In addition, it is possible to exhibit a design effect by presenting an uneven pattern that does not impair the transparency due to irregular reflection such as a fine textured surface and does not project the shadow of the fixed portion 11 to the outside.

  Further, as shown in FIG. 3, the lid cover 9 is made of synthetic resin and covers and covers a wraparound peripheral wall 9c that wraps around the outer peripheral surface of the cover body 8. The engagement piece 9a is covered on the end surface 9d of the wraparound peripheral wall 9c. A projecting wall 8d is formed integrally on the outer periphery of the lid body 8 and has a stepped surface 8c facing the end surface 9d. The projecting wall 8d projects on the outer periphery of the lid base 8, and the locking hole 8b is formed on the projecting wall 8d. It is formed so as to penetrate forward and backward. Thereby, since the transparent lid cover 9 wraps around and covers the outer periphery of the lid body 8, the wide range including the outer periphery around the outer periphery of the washing machine housing 4 that is visible from the front oblique side or from the front oblique upper side. The uniform transparent wall area can be expanded to improve the appearance texture.

  The fixing portion 11 is provided on the inner periphery of the illustrated locking hole 8b so as to be engaged with an engaging hole 9e or an engaging hook as illustrated in the engaging piece 9a and elastically engaged with the engaging hole 9e. It is composed of the check claw 8a and one of the rear opening edges of the locking hole 8a, so that the lid cover 9 can be fixed to the lid body 8 by elastic engagement.

  Further, the lid body 8 is sandwiched between the front and back frames 21 and 22 made of synthetic resin and constituting the lid frame 20 in the middle so as to form the window 7, and the front and back frames 21 and 22. The cover plate 9 is formed of a transparent window plate 23 made of a synthetic resin, the protruding wall 8d is provided on the front frame 21, and the lid cover 9 has a surface in which the outer peripheral surface of the surrounding wall 9c is substantially continuous with the outer peripheral surface of the protruding wall 22, The back frame 22 has an outward flange 22a at the front end thereof and is fitted to the front frame 21, and the flange 22a is fitted to a step portion 21a inside the rear end portion of the overhanging wall 8d. As a result, the lid frame 20 handles the front frame 21 elastically engaged with the lid cover 9 as one member to achieve a combined connection with the back frame 22 with the window plate 23 sandwiched therebetween, or the window plate 23, the front and back frames 21 and 22 can be handled as one member joined together in the middle, and the lid cover 9 is applied to the front frame 21 to be elastically engaged and fixed. Since the outer peripheral surface of the wraparound wall 9c is substantially continuous with the outer peripheral surface of the overhanging wall 8d, the outer surface is simplified in a wide area and including a three-dimensional area. Further, the back frame 22 has an outward flange 22a at its front end and is fitted to the front frame 21, and this flange 22a fits into the step 22b inside the rear end of the overhanging wall 8d. Since the side peripheral wall is located on the inner side from the outer peripheral surfaces of the lid cover 9 and the front frame 21, it is possible to reduce the feeling of thickness in the range of appearance in the closed state.

  Further, the surface 9b that allows light from the inside to be refracted and dispersed and transmitted is bent in a radial direction as shown by an imaginary line in FIG. One annular or arc-shaped bent convex surface, or one of an annular or arc-shaped bent wave surface continuously bent in the radial direction as shown by a solid line in FIG. 3, and an uneven surface spreading in all directions in a continuous bent shape. What is necessary is just to realize the prevention of the appearance of the engaging portion by the uneven pattern which does not impair the transparency. In order not to impair the transparency, it is a requirement that the surface is not matte, and the uneven surface spreading in all directions in a continuous bent shape needs to have a roughness more than that of a knurled pattern called a knurling.

More specifically, as shown in FIGS. 1 and 2, an upwardly inclined surface 4a is formed on the upper front side of the washing machine casing 4, and a circular access port 31 for taking in and out the laundry is provided on the inclined surface 4a. Is formed.
