(First embodiment)
Next, the detail of the upper cover 3 which is the principal part of the washing machine of this invention is demonstrated with reference to drawings. 4 is a perspective view of an upper lid used in the washing machine according to the present invention, FIG. 5 is a perspective view of a state where a glass plate is removed from the upper lid shown in FIG. 4, and FIG. 6 is a side of the upper lid shown in FIG. It is the expanded sectional view which expanded the cross section of the part.

  The upper lid 3 includes a hinge portion 30, a frame 31 (frame body), a glass plate 32 (an example of a plate-like member), and a handle portion 33. The hinge portion 30 connects the frame 31 and the upper surface member 2, and the upper lid 3 can be opened and closed by the hinge portion 30 (see FIGS. 2 and 3). As shown in FIG. 5, the frame 31 includes a support portion 311, a side wall portion 312, an adhesive portion 313, and a groove 314.

  The side wall 312 is a standing wall member formed so as to surround the upper lid 3. More specifically, the side wall portion 312 is a standing wall member that protrudes from the outer periphery of the flat support portion 311 in a direction orthogonal to the support portion 311. In other words, the support portion 311 can be said to be a flat plate-like member protruding inward from the side wall portion 312. An opening window 310 that is a through hole is formed in the central portion of the support portion 311. The support portion 311 and the side wall portion 312 are formed to be connected to each other, and here is an integrally molded body of resin. As shown in FIGS. 5 and 6, the frame 31 includes a support portion 311 and a side wall portion 312, so that it can be said that the frame 31 has a rectangular recess at the top.

  An adhesive portion 313 for adhering the glass plate 32 is provided inside the region surrounded by the side wall portion 312 of the support portion 311. The side provided with the bonding portion 313 is the upper surface (surface) of the upper lid 3. That is, the surface facing upward with the upper lid 3 closed is the upper surface of the upper lid 3. The bonding portion 313 is a portion provided on a plane in the support portion 311, and comes into contact with the glass plate 32 equally or substantially equally.

  As an example in which the bonding portion 313 is provided, the bonding portion 313 may be engraving or printing for positioning on the support portion 311, sticking of a seal, or the like. Alternatively, in the production instruction, for example, the position where the adhesive material is applied to the support portion 311 is specified (defined) such as “apply adhesive tape from the center of 2 mm from the groove” to provide the adhesive portion. It may be. Furthermore, the position where the adhesive material is provided is not limited as long as it is the upper surface of the support portion 311. In such a case, it can be said that the bonding portion is a place where the bonding material is provided.

  Moreover, you may provide the support part 311 not in the support part 311 but in a plate-shaped member (for example, glass plate 32). In this case, as an example in which the bonding portion 313 is provided, the bonding portion 313 may be stamping or printing for positioning, sticking a seal, or the like on the plate-like member. At this time, an appropriate method may be selected according to the material of the plate member. Alternatively, in the production instruction sheet, for example, it is indicated by specifying (specifying) the position where the adhesive material is applied to the plate-like member, such as “apply adhesive tape from the center of 2 mm from the end of the plate-like member”. A portion may be provided. Furthermore, the position where the adhesive material is provided is not limited as long as it is a surface facing the support portion 311 of the plate-like member. In such a case, it can be said that the bonding portion is a place where the bonding material is provided.

  In the present embodiment, the upper surface of the upper lid 3 is planar, and the support portion 311 is also planar, but the upper lid 3 may be formed in a curved shape for design reasons or other reasons. The part 311 may also be curved. In such a case, the bonding portion 313 may be provided on the curved surface in the support portion 311. Furthermore, the upper lid 3 may be formed from a combination of a curved surface and a flat surface. In such a case, the adhesion part 313 may be provided on a plane according to the shape and attachment position of the glass plate 32, and may be provided on a curved surface.

The glass plate 32 is firmly bonded to the bonding portion 313 using an adhesive material such as an adhesive sheet. The groove 314 is formed along the side wall portion 312 in a portion between the bonding portion 313 and the side wall portion 312 of the support portion 311. An annular packing is provided on the lower surface (back surface) of the upper lid 3 so as to surround the opening 21 of the upper surface member 2. This packing is provided inside the groove 314 on the upper surface.

  The glass plate 32 is a transparent plate-shaped member. The glass plate 32 only needs to be able to visually recognize the inside of the washing and dewatering tub 6 through the opening window 310 when the upper lid 3 is closed, and the portion overlapping the opening window 310 of the upper lid 3 of the glass plate 32 It is formed so as to have a light-transmitting property that can be confirmed (having transparency). The entire surface of the glass plate 32 may be transparent, but is not limited thereto. Since the glass plate 32 is bonded to the bonding portion 313 with an adhesive material, a portion to which the adhesive material adheres when the upper lid 3 is viewed from the upper surface may be formed opaque. The glass plate 32 is preferably tempered glass.

  By forming in this way, when the upper lid 3 is viewed from the upper surface, it is possible to prevent the user from visually recognizing the adhesive material (adhered portion), and thereby to improve the design of the upper lid 3. . Examples of the opaque method include a method for forming a thin film such as a metal and a method for performing printing, but are not limited thereto. In the present embodiment, the plate-like member has a light-transmitting configuration, and thus is made of glass. However, the present invention is not limited to this, and may be made of a resin such as an acrylic plate. . A material that has translucency and has a characteristic that the inside of the washing machine A can be sealed when the upper lid 3 is closed can be widely used. Further, when it is not necessary to visually recognize the inside of the washing machine A in a state where the upper lid 3 closes the opening 21, the plate-like member is formed of an opaque material (metal, resin, etc.) Also good. Alternatively, the opening window 310 may not be provided on the upper lid.

  As shown in FIGS. 4 and 5, the handle portion 33 is rotatably supported by the frame 31 and includes a handle portion 331 and an engaging portion 332. The handle portion 331 is a portion that is gripped when the user opens or closes the upper lid 3. The engaging portion 332 is a flat plate-like member, and a through hole (engagement hole) 333 is formed in the central portion. The upper surface member 2 is provided with a wedge-shaped engaging convex portion 25 whose upper side is formed obliquely, and the upper lid 3 is locked by engaging the engaging convex portion 25 with the through hole 333. .

  Further, the handle portion 33 is urged so that the engaging convex portion 25 engages with the through hole 333 using an elastic force such as a spring. By energizing in this way, the user operates the handle portion 33 so that the upper lid 3 is opened. When the user grips and rotates the handle portion 331, the engagement hole 333 and the engagement convex portion 25 of the engagement portion 332 are disengaged, and the upper lid 3 can be opened.

  As described above, the glass plate 32 is inserted into the concave portion formed by the support portion 311 and the side wall portion 312 of the upper lid 3 and fixed to the adhesive portion 313 with an adhesive material. A gap is formed between the outer peripheral surface of the glass plate 32 and the inner peripheral surface of the side wall portion 312 so that the frame 31 and the glass plate 32 can be inserted into the concave portion even if there is an error in manufacturing. The dimensions are as follows. If a liquid such as water or washing liquid spills on the glass plate 32 with the upper lid 3 closed, the liquid enters between the glass plate 32 and the side wall 312.

  In the washing machine A, the bonding portion 313 and the glass plate 32 are bonded and fixed with an adhesive material such as a pressure-sensitive adhesive sheet, and since the adhesive material has a certain thickness, the bonding portion 313 and the support portion 311 including the bonding portion 313 are included. A fine gap is formed between them. Since there is a fine gap between the support portion 311 and the glass plate 32, the liquid easily enters the back of the gap between the support portion 311 and the glass plate 32 due to a capillary phenomenon. When the liquid that has entered the gap between the support portion 311 and the glass plate 32 comes into contact with the adhesive material, the adhesive force of the adhesive material is reduced, which may cause the glass plate 32 to peel off.

  Therefore, in the washing machine A according to the present invention, the groove 314 is formed in a portion between the adhesive portion 313 and the side wall portion 312 of the support portion 311. Thus, by forming the groove 314, the liquid that has entered the outer peripheral surface of the glass plate 32 and the inner peripheral surface of the side wall portion 312 enters between the glass plate 32 and the support portion 311 by capillary action. It is restrained to do. Next, the groove 314 for suppressing the capillary phenomenon will be described.

  As shown in FIGS. 5 and 6, the groove 314 is formed along the side wall portion 312 in a portion adjacent to the side wall portion 312 on the upper surface of the support portion 311. Then, when the glass plate 32 is bonded to the bonding portion 313 with an adhesive material, the groove 314 is formed so that the edge portion of the glass plate 32 reaches the middle portion of the groove 314. In the upper lid 3 of the washing machine A according to the present invention, the groove 314 and the side wall 312 are formed so as to be adjacent to each other. The above-mentioned “so as to reach the middle portion” does not mean that the edge portion of the glass plate 32 needs to be positioned at the exact center of the width of the groove 314, but the glass plate above the groove 314. This indicates that the 32 edge portions are positioned.

  As described above, since the groove 314 is formed, the liquid flows into the groove 314, so that the liquid does not easily come into contact with the surface of the glass plate 32 facing the support portion 311. Further, the gap between the glass plate 32 and the bottom portion of the groove 314 is large, and the capillary phenomenon that occurs in the gap between the glass plate 32 and the bottom of the groove 314 is less likely to occur. As a result, the capillary phenomenon prevents the liquid from entering the back of the gap between the glass plate 32 and the support portion 311, suppresses the liquid from contacting the adhesive material, and suppresses the occurrence of peeling of the glass plate 32. can do.

By suppressing the glass plate 32 from peeling from the frame 31, it is possible to suppress a decrease in the sealing performance of the washing machine A. As a result, the operation of the washing machine A (for example, washing, rinsing, dehydration, drying, etc.) can be stably performed over a long period of time.

  In the present embodiment, the adhesive portion 313 is provided at a position close to the groove 314 of the support portion 311, but is not limited to this. For example, it may be provided near the center of the support portion 311 or may be provided near the opening window 310 of the support portion 311. That is, when designing, an appropriate position may be set in consideration of a reason for design and a reason for reliability.

(Second Embodiment)
Another example of the washing machine according to the present invention will be described with reference to the drawings. FIG. 7A is an enlarged cross-sectional view of an upper lid used in another example of the washing machine according to the present invention. The upper lid 3A shown in FIG. 7A has the same configuration as the upper lid 3 except that the adhesive portion 313a of the frame 31a is different. Therefore, substantially the same parts are denoted by the same reference numerals and detailed description of the same parts is omitted.

  As illustrated in FIG. 7A, the frame 31 a includes an adhesive portion 313 a that protrudes upward from the support portion 311. The adhesive portion 313a is provided (formed) in a strip shape extending along the side wall portion 312. And while arrange | positioning adhesive materials, such as an adhesive sheet, on the upper surface of the adhesion part 313a, the glass plate 32 is adhere | attached. Thus, by making the adhesion part 313a into the shape which protruded from the support part 311, the clearance gap between the support part 311 and the glass plate 32 is enlarged, a capillary phenomenon is suppressed, and contact with a liquid and adhesive material is carried out. It can be effectively suppressed.

  Other features are the same as in the first embodiment.

(Modification)
Another example of the washing machine according to the present invention will be described with reference to the drawings. FIG. 7B is a cross-sectional view of a modification of the upper lid shown in FIG. 7A. As illustrated in FIG. 7B, the upper lid 3A2 includes an inclined portion 311a that is inclined downward from the adhesive portion 313a toward the groove 314. With such a configuration, the gap between the inclined portion 311a and the glass plate 32 in the vicinity of the groove 314 in which the liquid is accumulated can be increased, and the liquid accumulated in the groove 314 is bonded to the bonding portion 313a by capillary action. Can be suppressed.

(Third embodiment)
Another example of the washing machine according to the present invention will be described with reference to the drawings. FIG. 8 is a perspective view schematically showing an upper lid used in another example of the washing machine according to the present invention. The upper lid 3B shown in FIG. 8 has the same configuration as the upper lid 3 except that the groove 314b of the frame 31b is different. Therefore, substantially the same parts are denoted by the same reference numerals and detailed description of the same parts is omitted. Moreover, in FIG. 8, illustration of a glass plate is abbreviate | omitted for convenience.

  In the upper lid 3 of the first embodiment, the frame 31 has a rectangular shape in plan view, and a side wall portion 312 is formed over the entire periphery. A groove 314 is formed at a position adjacent to the inner peripheral surface of the side wall portion 312 of the support portion 311. The groove 314 is formed so as to be closed once along the side wall portion 312. In such a configuration, even when a certain amount of liquid flows into the gap between the inner peripheral surface of the side wall portion 312 and the outer peripheral surface of the glass plate 32, the liquid reaches (contacts) the adhesive material of the adhesive portion 313. Can be suppressed. The liquid accumulated in the groove 314 evaporates by natural drying, so that the liquid accumulated in the groove 314 can be processed.

  However, when a large amount of liquid flows between the outer peripheral surface of the glass plate 32 and the inner peripheral surface of the side wall portion 312, it is difficult to process the liquid sufficiently by natural drying, and the liquid accumulated in the grooves 314 is not glass. The possibility of coming into contact with the surface of the plate 32 facing the support portion 311 is increased. As a result, there is a possibility that liquid may enter the gap between the glass plate 32 and the support portion 311 and come into contact with the adhesive material of the adhesive portion 313 due to capillary action.

  In the present embodiment, in order to prepare for such a case where natural drying is difficult, the upper lid 3B is employed, and a drainage channel 23 is provided on the upper surface of the upper surface member 2 so as to surround the opening 21.
