First Embodiment
Next, the details of the upper lid 3 which is the main part of the washing machine of the present invention will be described with reference to the drawings. 4 is a perspective view of the upper lid used in the washing machine according to the present invention, FIG. 5 is a perspective view of the upper lid shown in FIG. 4 with the glass plate removed, and FIG. 6 is the 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 30, a frame 31 (frame), a glass plate 32 (an example of a plate-like member), and a handle 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 portion 312 is a standing wall member formed so as to surround the periphery of the upper lid 3. More specifically, the side wall portion 312 is an upright wall member protruding in the direction orthogonal to the support portion 311 from the outer periphery of the flat support portion 311. From another point of view, it can be said that the support portion 311 is a flat member projecting inward from the side wall portion 312. An opening window 310, which is a through hole, is formed in the central portion of the support portion 311. The support part 311 and the side wall part 312 are connected and formed, and here, they are a resin integral molding. As shown in FIGS. 5 and 6, the frame 31 includes the support portion 311 and the side wall portion 312, so that it can be said that the frame 31 has a rectangular recess at the top.

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

  In addition, as an example in which the adhesion part 313 is provided, the adhesion part 313 may be marking or printing for positioning on the support part 311, attachment of a seal, or the like. Alternatively, in the production instruction, for example, a bonding portion is provided by specifying (defining) a position at which the bonding material is to be bonded to the support portion 311, such as “sticking an adhesive tape from the center to 2 mm from the groove”. You may Furthermore, if it is the upper surface of the support part 311, there may be no restriction | limiting in the position which provides an adhesion material. In such a case, the bonding portion can be said to be 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 marking, printing, sticking of a seal, or the like for positioning on a plate-like member. At this time, an appropriate method may be selected according to the material of the plate-like member. Alternatively, in the production instruction, for example, "adhere the adhesive tape from the center of the plate 2 mm from the center of the plate", etc. A part may be provided. Furthermore, if it is a surface facing the support part 311 of a plate-shaped member, there may be no restriction | limiting in the position which provides an adhesion material. In such a case, the bonding part can be said to be a place where the bonding material is provided.

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

  The glass plate 32 is firmly bonded to the bonding portion 313 using a bonding material such as an adhesive sheet. The groove 314 is formed along the side wall 312 at a portion between the bonding portion 313 of the support portion 311 and the side wall 312. An annular packing is provided on the lower surface (rear 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 top surface.

  The glass plate 32 is a transparent plate-like member. The glass plate 32 is only required to be able to view the inside of the washing and dewatering tank 6 through the opening window 310 at least 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 is It is formed to have translucency (transparency) to such an extent that it can confirm. 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 the bonding material, the portion to which the bonding material adheres may be opaque when the upper lid 3 is viewed from the top. In addition, as the glass plate 32, it is preferable to use tempered glass.

By forming in this manner, when the upper lid 3 is viewed from the upper surface, it is possible to suppress the user from visually recognizing the adhesive material (adhesive portion), thereby enhancing the design of the upper lid 3 . In addition, although the thing which forms thin films, such as a metal etc., and the thing which gives printing etc. can be mentioned as a method of making it opaque, it is not limited to this. Further, in the present embodiment, since the plate-like member has a light transmitting property, it is made of glass, but it is not limited to this. For example, it may be made of resin such as an acrylic plate. . A wide range of materials can be adopted which have a light transmitting property and can seal the inside of the washing machine A when the upper lid 3 is closed. Moreover, 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.) It is 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 engagement portion 332. The handle portion 331 is a portion held by the user when the upper lid 3 is opened or closed. The engagement portion 332 is a flat plate-like member, and a through hole (engagement hole) 333 is formed in a central portion. The upper surface member 2 is provided with a hook-shaped engaging convex portion 25 formed obliquely at the upper side, and the upper cover 3 is locked by engaging the engaging convex portion 25 with the through hole 333 .

  Further, the handle portion 33 is biased so that the engagement convex portion 25 engages with the through hole 333 by using an elastic force such as a spring. By biasing in this manner, the user operates the handle portion 33 to open the upper lid 3. When the user holds and rotates the grip portion 331, the engagement between the engagement hole 333 of the engagement portion 332 and the engagement convex portion 25 is released, and the upper lid 3 can be opened.

  As described above, the glass plate 32 is inserted into the recess formed by the support portion 311 and the side wall portion 312 of the upper lid 3, and is fixed to the adhesive portion 313 with the 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 above-mentioned recess even if there is a manufacturing error. The dimensions are as follows. When liquid such as water or washing liquid spills on the glass plate 32 in a state where the upper lid 3 is closed, the liquid infiltrates between the glass plate 32 and the side wall portion 312.

  In the washing machine A, the adhesive portion 313 and the glass plate 32 are adhered and fixed with an adhesive material such as a pressure sensitive adhesive sheet, and the adhesive material has a certain thickness. Fine gaps are formed between the two. Since the gap between the support portion 311 and the glass plate 32 is a fine gap, the liquid can easily enter the back of the gap between the support portion 311 and the glass plate 32 by capillary action. When the liquid that has entered the gap between the support portion 311 and the glass plate 32 comes in contact with the adhesive material, the adhesive force of the adhesive material may be reduced to cause the peeling of the glass plate 32.

  So, in the washing machine A concerning this invention, the groove | channel 314 is formed in the part between the adhesion part 313 of the support part 311, and the side wall part 312. As shown in FIG. Thus, by forming the groove 314, the liquid that has infiltrated into the outer peripheral surface of the glass plate 32 and the inner peripheral surface of the side wall portion 312 infiltrates between the glass plate 32 and the support portion 311 by capillary action. It is suppressed 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 312 at a portion close to the side wall 312 of 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 such that the peripheral 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 portion 312 are formed to be adjacent to each other. Note that “to reach the middle part” described above does not mean that the peripheral part of the glass plate 32 needs to be positioned at the exact center of the width of the groove 314, and the glass plate above the groove 314 It is shown that the 32 edge portions are positioned.

As described above, since the liquid flows into the groove 314 by the formation of the groove 314, the liquid is less likely to contact the surface of the glass plate 32 facing the support portion 311. Further, the gap between the glass plate 32 and the bottom of the groove 314 is large, and the capillary phenomenon generated in the gap between the glass plate 32 and the bottom of the groove 314 is less likely to occur. Thereby, by capillary action,
It is possible to suppress the liquid from infiltrating deep in the gap between the glass plate 32 and the support portion 311, to suppress the liquid from coming into contact with the adhesive material, and to suppress the occurrence of peeling of the glass plate 32.

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

  In the present embodiment, the bonding portion 313 is provided at a position close to the groove 314 of the support portion 311, but the present invention 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 design reasons, reliability reasons, and the like.

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 the 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 bonding portion 313a of the frame 31a is different. Therefore, substantially the same parts will be denoted by the same reference numerals and detailed descriptions of the same parts will be omitted.

  As shown to FIG. 7A, the flame | frame 31a is provided with the adhesion part 313a which protruded above the support part 311. As shown in FIG. The bonding 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. As described above, by making the bonding part 313 a project from the supporting part 311, the gap between the supporting part 311 and the glass plate 32 is enlarged to suppress the capillary phenomenon and the contact between the liquid and the bonding material is made. It can be effectively suppressed.

  The 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 shown in FIG. 7B, the upper lid 3A2 includes an inclined portion 311a which is inclined downward from the bonding 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 where the liquid is collected can be enlarged, and the liquid collected in the groove 314 is capillaryly adhered to the bonded portion 313a. 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 will be denoted by the same reference numerals and detailed descriptions of the same parts will be 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 a plan view, and a side wall portion 312 is formed over the entire circumference thereof. A groove 314 is formed at a position adjacent to the inner circumferential surface of the side wall portion 312 of the support portion 311. The groove 314 is formed along the side wall portion 312 so as to close one round. 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 bonding portion 313. It can be suppressed. Then, the liquid accumulated in the groove 314 can be treated by evaporation of the liquid accumulated in the groove 314 due to natural drying.

  However, when a large amount of liquid flows in 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 sufficiently process the liquid by natural drying, and the liquid accumulated in the groove 314 is glass The possibility of contacting 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 back of the gap between the glass plate 32 and the support portion 311 by capillary action and contact with the bonding material of the bonding portion 313.

  In the present embodiment, the upper lid 3B is adopted in preparation for the case where such processing by natural drying is difficult, and the drainage path 23 is provided on the upper surface of the upper surface member 2 so as to surround the opening 21. There is. The drainage path 23 is provided to drain water droplets, spilled water, washing liquid, etc. adhering to the inside of the upper lid 3 when the upper lid 3 is opened and closed. The groove 314b of the frame 31b of the upper lid 3B is provided with an open end 315 so that the liquid flows downward and flows out to the drainage channel 23 when the upper lid 3B is opened to stand up. The drainage path 23 is provided with a pipe for draining water to the drainage portion. The liquid flowing into the drainage path 23 through the pipe is drained (treated) to the drainage portion.

  More specifically, when the upper lid 3B is closed and the opening 21 of the upper surface member 2 is closed, the groove 314b is formed along the front side and the left and right sides. The rear end of the groove 314b along the left and right sides is an open end 315 so that the liquid flows out. By forming the groove 314b in this manner, when the upper lid 3B is opened and the opening 21 of the upper surface member 2 is opened, the open end 315 of the groove 314b is opened downward, so the liquid accumulated in the groove 314b is It flows out of the open end 315 into the drainage channel 23. Thereby, even if a large amount of liquid flows into the groove 314b, the liquid which has flowed in can be treated (discharged) efficiently.

  As the upper lid 3B, notches are configured to be open ends 315 at the left and right end portions of the portion that constitutes the back side of the side wall portion 312 when the opening 21 of the upper surface member 2 is closed. It is not limited to this. For example, when the opening 21 of the upper surface member 2 is closed, a plurality of notches may be formed at regular intervals in a portion that constitutes the back side of the side wall portion 312. With such a configuration, when the opening 21 is opened by the upper lid 3B, the liquid accumulated in the groove 314b formed along the side wall portion 312 constituting the back side is also efficiently flowed to the drainage path 23 be able to. Thereby, even if a large amount of washing liquid flows to the upper surface of the upper lid 3b, peeling of the glass plate 32 can be suppressed.

  Although not shown, the center in the lateral direction of the portion formed along the side wall portion 312 which constitutes the rear side of the groove 314b (the side which becomes lower when the upper lid 3B is opened) (or An open end may be formed at approximately the center). In such a configuration, it is preferable that the groove 314b be configured to incline downward toward the open end when the upper lid 3B is opened.

That is, the open end may be provided at the lower portion (downstream portion) of the groove when the upper lid is in the open state, and is preferably provided at the lowermost end (most downstream portion).

Fourth Embodiment
The further another example of the washing machine concerning this invention is demonstrated with reference to drawings. FIG. 9 is an enlarged perspective view of the vicinity of the handle portion of the upper lid used in still another example of the washing machine according to the present invention. The upper lid 3C shown in FIG. 9 has the same configuration as the upper lid 3 except that the groove 314c of the frame 31c is different. Therefore, substantially the same parts will be denoted by the same reference numerals and detailed descriptions of the same parts will be omitted. In the enlarged view of FIG. 9, the handle portion 33 is omitted for the sake of convenience.

  As shown in FIG. 3, in the upper surface member 2, when the upper lid 3 is closed in a state where the washing machine A is accurately level-adjusted and installed at the installation location (floor surface), the front side, that is, the handle 33 side is downward. Incline. Therefore, in the upper cover 3C according to the present embodiment, the water accumulated in the groove 314c is discharged using the inclination of the upper cover 3C when the upper cover 3C is closed.

  In the frame 31c, the side wall portion 312 formed to surround the outer periphery plays a role of a reinforcing member for enhancing the strength of the frame 31c. In this regard, the side wall portion 312 is preferably formed to completely surround the outer periphery of the frame 31c. However, the frame 31c is provided with the handle portion 33 so as to be rotatable, and the handle portion 331 of the handle portion 33 is disposed on the upper surface side of the upper lid 3C, and the engaging portion 332 is disposed on the lower surface side. Therefore, in order to attach the handle portion 33, the side wall portion 312 is broken at the portion where the handle portion 33 of the frame 31c is attached.

  A notch 316 is formed in the support portion 311 at a portion where the side wall portion 312 is interrupted. A portion where the groove 314 c intersects the notch 316 is an open end 315. In the frame 31 c, the liquid flowing from the open end 315 of the groove 314 c flows into the drainage channel 23 through the notch 316.

  Similar to the above-described upper lid 3, an annular packing is provided on the lower surface (rear surface) of the upper lid 3 </ b> C so as to surround the opening 21 of the upper surface member 2. In addition, the packing is provided inside the groove 314 c on the upper surface, and comes in contact with the upper surface of the upper surface member 2 inside the drainage path 23 of the upper surface member 2. By doing this, in the state where the upper lid 3C is closed, the opening 21 is sealed. Therefore, the liquid which has flowed into the drainage channel 23 does not flow into the water tank 5 or the washing and dewatering tank 6 even when the upper lid 3C is closed. In the drainage channel 23, a pipe for draining to the drainage portion is provided in a row. Therefore, even when the upper lid 3C is closed, the liquid flowing into the drainage passage 23 can be drained to the drainage portion.

  Thus, by forming the groove 314c and the notch 316, the liquid accumulated in the gap between the inner peripheral surface of the side wall 312 and the outer peripheral surface of the glass plate 32 is efficiently processed (discharged) even in the closed state of the upper lid 3C. can do.

  The other features are the same as those of the third embodiment.

Fifth Embodiment
The further another example of the washing machine concerning this invention is demonstrated with reference to drawings. FIG. 10 is an enlarged cross-sectional view schematically showing an upper lid used in still another example of the washing machine according to the present invention. FIG. 10 is a cross-sectional view in which the middle portion is omitted. The upper lid 3D shown in FIG. 10 has the same configuration as the upper lid 3 except that the groove 314d of the frame 31d is different. Therefore, substantially the same parts will be denoted by the same reference numerals and detailed descriptions of the same parts will be omitted.

  Depending on the configuration of the washing machine (the configuration of the top member), the upper lid, which is attached at an angle, may be attached to close the opening in a horizontal or substantially horizontal state. In such a case, when the upper lid is closed, the liquid accumulated in the groove becomes difficult to flow, and the liquid may reach the adhesive material.

Therefore, as shown in FIG. 10, the upper lid 3D has a slope such that the bottom surface 3141 of the groove 314d is inclined in the longitudinal direction when in the horizontal state. The lower end portion of the slope of the groove 314 d is an open end 315. In the washing machine having a configuration in which the opening 21 is closed with the upper lid 3D in a horizontal state, even if the liquid intrudes between the outer peripheral surface of the glass plate 32 and the inner peripheral surface of the side wall portion 312 in the state where the upper lid 3D is closed, It flows downward of the slope of the groove 314d. And it flows toward the drainage path 23 from the open end 315 formed in the lower end part of the inclination (discharged).

  Similar to the above-described upper lid 3, an annular packing is provided on the lower surface (rear surface) of the upper lid 3D so as to surround the opening 21 of the upper surface member 2. In addition, the packing is provided inside the groove 314 d on the upper surface, and comes in contact with the upper surface of the upper surface member 2 inside the drainage path 23 of the upper surface member 2. By doing this, in the state in which the upper lid 3D is closed, the opening 21 is sealed. Therefore, the liquid that has flowed into the drainage channel 23 does not flow into the water tank 5 or the washing and dewatering tank 6 even when the upper lid 3D is closed. In the drainage channel 23, a pipe for draining to the drainage portion is provided in a row. Therefore, even when the upper lid 3D is closed, the liquid flowing into the drainage passage 23 can be drained to the drainage portion.

  Thus, by forming the groove 314d, the liquid accumulated in the gap between the inner peripheral surface of the side wall 312 and the outer peripheral surface of the glass plate 32 can be efficiently processed (discharged) even when the upper lid 3D is in the horizontal state. Can.

  In the present embodiment, the inclination direction of the groove 314 d is the front-rear direction of the washing machine A, but the invention is not limited thereto. For example, it may be inclined in the left and right direction. In consideration of the case where the upper lid 3D is attached in an inclined manner, the inclination direction of the groove 314d extending in the inclined direction is the same as the inclined direction of the upper lid 3D when the upper lid 3D is attached in an inclined manner. The effect of the treatment (discharge) of the liquid can be enhanced, which is more preferable.

  The other features are the same as in the first embodiment.

  As shown in FIG. 11, in the groove 314 e formed in the frame 31 e, a plurality of through holes 317 are formed in the bottom surface portion 3141. The formation of the through hole 317 allows the liquid flowing into the groove 314 e to flow through the through hole 317 into the drainage channel 23.

  Similar to the above-described upper lid 3, an annular packing is provided on the lower surface (rear surface) of the upper lid 3E so as to surround the opening 21 of the upper surface member 2. Further, the packing is provided inside the groove 314 e on the upper surface, and comes in contact with the upper surface of the upper surface member 2 inside the drainage path 23 of the upper surface member 2. By doing this, in the state where the upper lid 3E is closed, the opening 21 is sealed. Therefore, the liquid that has flowed into the drainage channel 23 does not flow into the water tank 5 or the washing and dewatering tank 6 even when the upper lid 3E is closed. In the drainage channel 23, a pipe for draining to the drainage portion is provided in a row. Therefore, even when the upper lid 3E is closed, the liquid flowing into the drainage path 23 can be drained to the drainage portion.

  Thus, by forming the through holes 317 on the bottom surface 3141 of the groove 314e, the liquid accumulated in the gap between the inner peripheral surface of the side wall 312 and the outer peripheral surface of the glass plate 32 even in the closed state of the upper lid 3E. It can be processed (discharged) efficiently.

  In the present embodiment, the through hole 317 is formed on the bottom surface 3141 of the groove 314 e. However, one large through hole 317 may be provided, or a plurality of the through holes 317 may be provided at appropriate intervals. It may be formed side by side. In addition, the bottom of the groove 314e may be formed of a material such as mesh that is permeable to liquid.

  In each of the above-described embodiments, the liquid flowing between the side wall portion of the upper lid and the glass plate flows into the drainage channel 23. The drainage path 23 is connected to the drainage portion, but is not limited to this, and may be configured to flow into the water tank when the upper lid is opened. Also, the open end of the groove or the through hole may be formed to flow directly into the water tank.
