[18] When the cleaning tank is accommodated in the washing machine main body in the slide open type dish washing machine, the present invention prevents the interference between the inner lid and the cleaning tank closing the upper opening of the cleaning tank, and increases the amount of drawout from the washing machine main body of the cleaning bath. It relates to a dish washer provided with a means for concealing the gap between the washing tank to be generated and the cleaner body.
[19] [Prior art]
[20] FIG. 16 shows Japanese Patent No. 3129318, which is one of the prior art examples of a slide-open type dish washer that takes in and cleans dishes from a washing machine body. As shown in the figure, the cleaning tank 14 which opens upward is configured to be able to take out and forward from the front opening of the cleaner main body 15, and the withdrawal from the washing machine main body 15 of the washing tank 14 is 1st. The slide rail 16 comprises a pair of slide rails in which the second slide rail 17 is mounted via a rotating body such as a ball bearing. Since the first slide rails 16 are fixed to both inner surfaces of the cleaner main body 15, and the second slide rails 17 are fixed to both outer surfaces of the washing tank 14, the washing tank 14 is opened. When withdrawing or pushing from the cleaner main body 15, the 2nd slide rail 17 fixed to the washing tank 14 moves in the 1st slide rail 16, and since the rotating body is interposed between both rails, The washing tank 14 can be withdrawn from the washing machine main body 15 by smooth movement.
[21] In the slide-open dishwasher, when the washing tank 14 is accommodated in the washing machine main body 15, the inner lid 11 disposed above the washing machine main body 15 descends to close the opening of the washing tank 14, It is comprised so that the washing | cleaning water sprayed from the washing | cleaning nozzle 8 may not scatter outside (for example, Unexamined-Japanese-Patent No. 2001-275916). The inner lid 11 is held in the cleaner main body 15 by a link mechanism (not shown) and biased toward the front upper side by a biasing means. When the washing tank 14 is accommodated in the washing machine main body 15, the inner lid 11 is resisted by the biasing means by the biasing means provided by the coupling means provided in the washing tank 14 by the pushing operation immediately before the completion of the receiving. It descends by a link mechanism and closes the opening part of the washing tank 14. On the other hand, since the pressurization by the coupling means is released when the washing tank 14 is drawn out from the cleaner main body 15, the inner lid 11 is moved upwards by the bias by the biasing means. The upper part of the washing tank 14 is opened.
[22] However, in the structure of the said prior art, even if the washing tank 14 is pulled out from the washing machine main body 15 to the extraction end position, the rear part of the inner tank of the washing tank 14 will remain in the washing | cleaning main body 15, There has been a problem that putting in and out of tableware from the rear part of the tank 14 becomes difficult.
[23] Thus, in order to facilitate the withdrawal of dishes from the washing tank 14, the washing tank 14 is pulled out so that the upper portion of the inner wall rear surface of the washing tank 14 is located at least in front of the front end of the washing machine main body 15. If possible, a space | interval occurs between the back surface of the washing tank 14 and the front surface of the washing machine main body 15. FIG.
[24] When the washing tank 14 is taken out to a position where an interval occurs with the washing machine main body 15, when a plurality of dishes are stored in the withdrawn washing tank 14 and the weight is increased, the rear end of the washing tank 14 When the side is raised, as shown in FIG. 17, when the cleaning tank 14 is pushed into the cleaner body 15, the rear end upper portion of the cleaning tank 14 interferes with the inner lid 11. The upper part of the rear end of the washing tank 14 may be caught by the inner lid 11.
[25] SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and its object is to prevent interference between the cleaning tank and the inner lid, and at the same time increase the amount of the cleaning tank withdrawn from the cleaning body of the cleaning tank. It is to provide a dish washer provided with a means for concealing the gap therebetween.
[26] [Means for solving the problem]
[27] The present invention for achieving the above object is disposed with respect to the washing machine body formed of a substantially box-shaped body opening forward, so that the cleaning tank opening upwards can enter and exit from the front opening of the cleaner body by the slide rail, A dishwasher having an inner lid for lowering in association with a movement operation for accommodating the washing tank in a washing machine body and closing an upper opening of the contained washing tank, wherein the washing tank is formed by at least an upper portion of the rear side of the inner wall of the washing machine. It is possible to draw out to the drawing end position located on the front side of the front end of the front side, and at the same time, the extension part which extended the upper surface back of the washing tank toward the back side was provided, and this extension part took out the washing tank to the said drawing end position. When the tip is located under the inner lid It is characterized in that it is formed in an extended length.
[28] According to the above configuration, since the extended portion formed behind the upper surface of the cleaning tank has a length at which the tip end is located under the inner lid even when the cleaning tank is taken out to the withdrawal end position, a large number of dishes are stored in the extracted cleaning tank and the weight is increased. As the rear end side of the cleaning tank is increased, the extension part slides the lower surface of the inner lid even if the operation of pushing the cleaning tank into the cleaner body in such a state prevents the cleaning operation of the cleaning tank. It doesn't work. In particular, when the withdrawal amount of the cleaning tank is increased, the amount of rising of the rear end side of the cleaning tank increases due to the weight increase, so when the cleaning tank is pushed in when there is no extension, the rear end of the raised cleaning tank may collide with the side of the inner lid and be damaged. Concerns are resolved.
[29] In the above configuration, the extension portion extends in a plate shape from the rear of the upper surface of the cleaning tank toward the rear side, thereby concealing an upper gap generated between the rear of the cleaning tank and the washing machine main body when the extraction amount of the cleaning tank is increased. The effect can also be obtained.

As a result, the hose holder 46 rotates to stabilize the connection state of the water supply hose 38 and the drain hose 39 with respect to the moving washing tank 32.
[33] In addition, as shown in FIGS. 5 and 6, the slide rails 33 are fixed rails 41 fixed to inner surfaces of both side surfaces of the cleaner main body 31, and outer surface sides of both sides of the cleaning tank 32. The intermediate rail 43 is sandwiched between the movable rails 42 fixed to the rails via ball bearings 47, and is constituted by a three-stage structure. The fixing rail 41 is provided with a horizontal surface 44a extending from its side and a vertical surface 44b bent at right angles in the vertical direction from the horizontal surface 44a to form an attachment portion 44 formed in the L-shaped cross section. It is. This slide rail 33 is mounted inside the both side surfaces of the cleaner main body 31 as shown in FIGS.
[34] 7 and 8, the washing machine main body 31 is formed in a substantially box shape in which the front surface is opened by a metal plate material, and on both sides thereof, the attachment rails 44 are held to temporarily fix the slide rails 33, Or the accommodating part 48 and the clamping part 49 for temporarily fixing are formed. As shown in FIG. 8, the receiving portion 48 and the clamping portion 49 are formed at intervals corresponding to the vertical height dimension of the attachment portion 44 by protruding the plate surface of the cleaner main body 31. As shown in the drawing, when the upper end of the vertical surface 44b of the attachment portion 44 is inserted into the clamping portion 49, and the horizontal surface 44a is pushed onto the receiving portion 48, the slide rail 33 is used as a washing machine body ( 31) is temporarily fixed to the side. The temporarily fixed slide rail 33 has a screw 51 coupled to two screw holes 50 formed in the attachment portion 44 corresponding thereto from two fixing holes formed in the cleaner main body 31. It is fixed.

The support part 45 is mounted on the movable rail 42 of the slide rail 33 attached to the cleaner main body 31, and the cleaning tank 32 is slid backwards on the movable rail 42. As shown in FIG. As shown in FIG. 11, the fitting protrusion 52 which protrudes toward the rear from the back of the support part 45 is cut-up part 53 cut-up in the shape of the letter L at the back side of the movable rail 42. As shown in FIG. ) Is inserted into the projection 54 projecting downward from the front side of the support portion 45, the front end is inserted into the opening 55 (see Fig. 5) formed in the movable rail 42, the slide rail 33 The position of the cleaning tank 32 relative to) is achieved. The cleaning tank 32 is positioned on the slide rails 33 on both sides thereof so as to be in a stable mounting state. However, the cleaning tank 32 is formed in the movable rails 42 from a fixing hole formed in the front side of the support part 45 to maintain this state. By engaging the screw with the screw hole, the cleaning tank 32 is fixed to the movable rail 42 (see FIG. 8).
[36] The slide rail 33 has a three-stage structure as described above, and when the washing tank 32 is taken out from the washing machine main body 31, the movable rail 42 to which the washing tank 32 is fixed is placed on the intermediate rail 43. It moves smoothly, the intermediate rail 43 moves on the stationary rail 41 late to the movement of the movable rail 42. As shown in FIG. 10A and 10B show the moving states of the movable rail 42 and the intermediate rail 43 according to the withdrawal operation of the washing tank 32 from the washing machine main body 31. Specifically, FIG. 10A shows the washing tank 32. ) Is accommodated in the washer main body 31, and FIG. 10B shows a state where the washer 32 is pulled out to the withdrawal end position. When the withdrawal operation of the washing tank 32 starts from the state shown in FIG. 10A, the movable rail 42 to which the washing tank 32 was fixed starts moving on the intermediate rail 43, as shown by a virtual line. do. As the movable rail 42 moves, the retainer 90 (see FIG. 6) for capturing a plurality of ball bearings 47 interposed between the movable rail 42 and the intermediate rail 43 at predetermined intervals is always movable rail ( The intermediate rail 43 starts to move on the fixed rail 41 by interposing between the 42 and the intermediate rail 43 as the movable rail 42 moves to a predetermined position. Between the intermediate rail 43 and the fixed rail 41, there is a retainer 90 for capturing a plurality of ball bearings 47 at predetermined intervals, like the movable rail 42, and as shown in Fig. 10B, When the tank 32 is pulled out to the withdrawal end position, about 1/2 length of the intermediate rail 43 corresponding to the length of the retainer 90 is fitted in the fixed rail 41, and about 1 Move until / 2 protrudes from the fixed rail 41. In addition, since the movable rail 42 can be moved until about half of the intermediate rail 43 is inserted and about half of the movable rail 42 protrudes from the intermediate rail 43, the washing tank 32 It is possible to increase the withdrawal amount from the washing machine main body 31 of).
[37] In addition, in the slide rail 33 having a three-stage structure as described above, even when the movable rail 42 is largely drawn out from the fixed rail 41, since the intermediate rail 43 exists between both rails, Even if a load of the cleaning tank 32 is applied to the movable rail 42, the cleaning tank 32 can be supported by the slide rail 33.
[38] According to the above structure, as shown in FIG. 1, the upper portion "A" of the inner wall rear surface of the inner tank 34 is located at least in front of the front end "B" of the cleaner body 31. Since it can be taken out from the washing | cleaning main body 31 until the state, and the state without a shielding object can be obtained in the whole upper part of the inner tank 34, the operation | work of putting out and disposing of tableware and the residual process after washing becomes easy. However, when the withdrawal amount of the washing tank 32 is increased, a gap is generated between the rear of the washing tank 32 and the front end of the washing machine main body 31, and as shown in FIG. 4, the washing tank 32 is shown. Members, such as the electric pump 37 arrange | positioned at the back surface of the inside, are externally exposed from a clearance gap. In particular, when the electric pump 37 is arrange | positioned so that it may be accommodated in the recessed part 74 formed in the back surface of the tank 79, the electric pump 37 will expose much outside. Such a state is unfavorable to look at, and there is a risk of an accident or a breakdown caused by touching the electrical equipment such as the electric pump 37 when the child makes a prank such as putting a hand or a metal object through the gap. In order to solve this problem, a rearward concealment plate is provided around the rear surface of the cleaning tank 32 to conceal the gap.
[39] An under cover 56 is attached to the lower surface of the cleaning tank 32 and lower portions of the support portions 45 on both sides thereof to cover the lower surface of the cleaning tank 32 as shown in FIGS. 4 and 11. Since the rear end side of the under cover 56 is diagonally illustrated in FIG. 4, the under cover extension portion 56a extending rearward is formed so as to be lower than the lower surface and the slide rails 33 on both sides. The site can be concealed.
[40] By attaching a side concealment plate 58 extending from the side of the cleaning tank 32 toward the rear, as shown in FIGS. 4 and 11, the portion above the support 45 on both sides of the cleaning tank 32, The external exposure of the member disposed on the rear surface of the cleaning tank 32 can be concealed from the side surface. In addition, the same effect can be obtained even if the cover part which extends in the plate shape toward both rear surfaces of the back side of the washing tank 32 integrally with the washing tank 32 is resin-molded.
[41] As shown in FIG. 11 and FIG. 12A, the upper back of the washing tank 32 can be concealed by forming the extension part 57 which extended the rear end part of the upper surface of the tank 79 to plate shape toward the rear. As shown in FIG. 14, the extension portion 57 is in the state where the cleaning tank 32 is pulled out to the withdrawal end position, and the tip portion “E” of the extension portion 57 is located below the inner lid 60. It is formed with an extended length in which it is located.
[42] As shown in the schematic diagram in FIG. 13, the inner lid 60 has a link mechanism provided on one side of the washing machine main body 31 with a main body side support point 93 and the other as an inner lid side support point 94 ( Since it is arrange | positioned up and down by 62, and it is biased forward and upward by the spring 63, in the state with which the washing | cleaning tank 32 was withdrawn from the washing | cleaning main body 31, it applies to the bias of the said spring 63. FIG. It is in the upper position shown by dashed line. The washing tank 32 is pushed into the washing machine main body 31, the inner lid 60 is extruded to the rear side by the pressing piece 59 formed on the front upper surface of the tank 79, and the inner lid 60 is In response to the bias of the spring 63, the inner lid 60 is lowered obliquely downward from the front by the link mechanism 62 to the opening of the tank 79 of the cleaning tank 32 pushed to the receiving end position. The center part 95 is fitted, and the inside of the inner tank 34 is sealed by the packing 78 arrange | positioned around the center part 95. FIG.
[43] In the state in which many dishes are accommodated in the inner tank 34 of the washing tank 32 withdrawn from the washing machine main body 31, and the weight of the washing tank 32 increased, the washing tank 32 supported by the slide rail 33 was carried out. ) Tends to be in a state where the front side goes down and the rear side goes up. When the cleaning tank 32 is pushed into the cleaner main body 31 in such a state, the extension part 57 which extends from the rear end of the tank 79 becomes the front end part "C" or "D" of the inner lid 60 (FIG. 14), as described above, the extension portion 57 has a center portion 95 of the inner lid 60 even when its tip portion “E” pulls out the cleaning tank 32 to the withdrawal end position. Since the extension portion 57 is formed to have an extension length positioned rearward and downward from the front end portion "D" of the front end portion, the extension portion 57 has a washing tank 32 pushed into the cleaner body 31 of the inner lid 60. Guided along the lower surface, it can be guided to the receiving end position.
[44] The extension part 57 does not need to be formed to have an extended length until reaching the bottom of the inner lid 60, provided that it is only for concealing the rear of the cleaning tank 32, but the cleaning tank 32 is not In order to serve as a guide for guiding along the lid 60, an extension length leading down the inner lid 60 is essential. If only the action of the guide is required, as shown in Fig. 12B, the plurality of extension portions 57a may be formed to protrude, and there is no need to form the plate in particular.
[45] If the washing tank 32 is not pushed firmly into the receiving end position in the washing machine main body 31, the sealed state of the inner tank 34 by the inner lid 60 will become inadequate, and a leak will generate | occur | produce or the washing tank 32 There is a fear that the handle operation to maintain the accommodating state may become incomplete. Thus, in order to reliably guide the cleaning tank 32 to the receiving end position in the cleaner main body 31, an insertion mechanism 64 is provided on the slide rail 33 (Figs. 5, 6, 10a, and 10b). And the cleaning tank 32 can be reliably pushed to the storage end position in the cleaner main body 31.
[46] As shown in FIG. 15, the pulling piece 64 is attached to the side surface of the fixed rail 41 which comprises the slide rail 33, and the operation piece couple | bonds with the engaging piece 65 provided in the drawing mechanism 64. As shown in FIG. 66 is mounted on the side of the movable rail 42. In the state where the cleaning tank 32 is accommodated in the cleaner main body 31, the projection part 66a formed in the said operation piece 66 is between the pair of engagement projections 65a and 65b formed in the said engagement piece 65. Combining The front end of the spring shaft 68 is fitted to the coupling piece 65 so as to be movable, and a spring receiving cylinder 72 is provided on the other end side of the spring shaft 68, and the spring shaft 68 is provided therein. The coil spring 70 is accommodated by the spring accommodating part 73 provided in the other edge part.
[47] When the operation of taking out the cleaning tank 32 from the cleaner main body 31 is performed, the movable rail 42 moves, the engagement piece 65 is moved by the operating piece 66 fixed to it, and the spring shaft ( 68 is pulled and the coil spring 70 is compressed. A locking recess 71 is formed at one end of the side wall 69 which forms the groove in which the coupling piece 65 slides, and is engaged with the operation piece 66 by the movement of the movable rail 42. When the engaging projection 65a of the moving engagement piece 65 reaches the engaging recess 71, the engaging projection 65a enters into the engaging recess 71 and the projection 66a of the working piece 66. The bond with is released. By engaging the engaging projection 65a in the locking recess 71, the coil spring 70 is held in a compressed state by the spring receiving portion 73.
[48] When the operation of pushing the extracted cleaning tank 32 into the cleaner main body 31 is performed, the movable rail 42 moves to the rear side, and the engaging piece 66 is engaged by the locking recess 71. When the position of the piece 65 is reached, the projection 66a of the operation piece 66 engages and presses against the engaging projection 65b remaining on the side wall 69, so that the engaging projection of the engaging piece 65 is pressed. 65a escapes from the locking recess 71, and the locking state is released. Since the elastic return force of the coil spring 70 compressed by the release of the latch extends from the spring shaft 68 to the engaging piece 65 and the working piece 66, the movable rail 42 is applied to the cleaning tank 32. Even when the force of the push operation with respect to the state is not applied, it can move, and can push the washing tank 32 to the receiving end position in the washing machine main body 31. FIG.
[49] In the drawing-in mechanism 64, a coil spring 70 is provided on a spring receiving portion 73 attached to the tip of the spring shaft 68, using a spring receiving cylinder 72 for accommodating the coil spring 70 as a cylinder. The air damper which compresses the air in the spring container 72 by the spring accommodating part 73 when the compressed coil spring 70 elastically returns by giving the action of a piston simultaneously with the action | support of one end of the Since the effect of the present invention can be obtained, the movement speed decreases to the end of the introduction of the cleaning tank 32 into the cleaner main body 31, and the effect of quietly accommodating the cleaning tank 32 can be obtained.
[50] As described above, according to the present invention, an extension part is formed extending from the rear of the upper surface of the washing tank toward the rear, and the extension part is located at the bottom of the inner lid even when the distal end thereof pulls the washing tank from the cleaner body to the withdrawal end position. Since the change is caused in the upper and lower positions of the rear end due to the weight change of the washing tank, the washing tank pushed into the washing machine main body can be guided to the receiving position without colliding the rear end with the inner lid. In addition, by forming the extension portion in the shape of a plate, when the draw amount from the washing machine main body of the washing tank is set large, the effect as a concealing plate for concealing the gap generated between the rear of the washing tank and the washing machine main body can also be obtained.
