[0001] The present invention relates to a dishwasher.

Background Art

[0002] Patent Document 1 discloses an example of a conventional dishwasher. This dishwasher includes a housing, a washing tub, a lid, and a lifting mechanism.

[0003] The housing is open at the front. The washing tub is movable between a storage position where it is housed inside the housing and a drawer position where it moves forward from the storage position and is exposed outside the housing. The washing tub has an upwardly open tub opening and can accommodate the objects to be washed.

[0004] The lid is provided inside the housing. The lid is in a closing position where it closes the tub opening when the washing tub is in the storage position. The lid is movable between the closing position and a retracted position where it moves upward from the closing position to open the tub opening. The lifting mechanism is interlocked with the movement of the washing tub between the storage position and the drawer position, and moves the lid between the closing position and the retracted position.

[0005] More specifically, the lifting mechanism has a spring, two pairs of L-shaped links, and two pairs of guide members. The spring is provided between the housing and the lid, and biases the lid toward the retracted position. One end of each link is connected to the side edge of the lid. The other end of each link is swingably supported on the inner wall surface of the housing. A roller is rotatably supported at the bent portion of each link. Each guide member is provided on the side wall of the washing tub so as to correspond one-to-one to each link. Each guide member is positioned such that it can press the roller of each link downward.

[0006] When the washing tub moves from the drawer position to the storage position, the lifting mechanism moves each guide member backward to press the roller of each link downward, and swings each link against the spring, thereby moving the lid to the closing position.

[0007] On the other hand, in the lifting mechanism, when the washing tank moves from the storage position to the pull-out position, each guide member moves forward and away from the rollers of each link, causing the springs to swing each link in the opposite direction and move the lid to the retracted position. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Japanese Patent Publication No. 2002-165744 [Overview of the Initiative] [Problems that the invention aims to solve]

[0009] Incidentally, in the conventional dishwasher described above, the washing tub, which is movably supported by the housing, has play in the width direction relative to the housing. Each link, which is pivotably supported by the housing, has play in the width direction relative to the housing. The lids connected to each link have play in the width direction relative to each link.

[0010] Therefore, when the lid moves to the closed position in conjunction with the movement of the washing tank to the storage position, if the washing tank and the lid are positioned in the width direction via the housing and each link, errors due to play in these components tend to accumulate. As a result, it is difficult to improve the positioning accuracy of the lid in the width direction relative to the washing tank in this dishwasher.

[0011] This invention has been made in view of the above-mentioned conventional circumstances, and aims to solve the problem of providing a dishwasher that can improve the positioning accuracy of the lid in the width direction relative to the washing tank. [Means for solving the problem]

[0012] The dishwasher of the present invention has a housing that is open at the front, A washing tank is movable between a storage position housed within the housing and a pull-out position that moves forward from the storage position to be exposed outside the housing, and has an open top to accommodate the object to be washed. A lid provided within the housing, which is in a closed position that closes the tank opening when the washing tank is in the housing position, and which is movable between the closed position and a retracted position that is furthest above the closed position and opens the tank opening, A dishwasher comprising a lifting mechanism that moves the lid between the closed position and the retracted position in conjunction with the movement of the washing tub between the storage position and the pull-out position, The lifting mechanism is provided between the housing and the lid and includes a biasing means that biases the lid toward the retracted position, The washing tank is provided with a contact portion which abuts against the lid when the washing tank moves from the pull-out position to the storage position, causing the lid to move from the retracted position to the closed position, At least one pair of guided protrusions projecting outward in the width direction from the side edge of the lid so as to be spaced apart from each other, Each of the following is provided: at least one pair of guide portions supported on the inner wall surface of the housing so as to correspond one-to-one with each of the guided protrusions, each guide portion having a guide groove that extends to be inclined rearward and downward and into which the guided protrusion is inserted, and which causes the guided protrusion to slide along the guide groove when the lid moves between the closed position and the retracted position, Each of the guide sections includes a first restricting section that, when the cleaning tank is in the storage position, contacts the side wall of the cleaning tank from the outside in the width direction to restrict the misalignment of the cleaning tank in the width direction, The present invention is characterized by having a second restricting portion located above the first restricting portion, which, when the cover is in the closed position, contacts the side edge of the cover from the outside in the width direction to restrict the positional displacement of the cover in the width direction.

[0013] In the dishwasher of the present invention, the lifting mechanism restricts the front-to-back position of the lid relative to the washing tub by causing the contact portion of the washing tub to move backward and contact the lid when the washing tub moves from the pull-out position to the storage position.

[0014] Next, the contact portion presses the lid backward against the biasing means, moving it to the closed position. At this time, each guide portion slides the guided protrusion backward and downward along the guide groove, so that the lid can be moved to the closed position with high reliability.

[0015] Furthermore, the first restricting portion of each guide section restricts the widthwise displacement of the cleaning tank by contacting the side wall of the cleaning tank from the outside in the width direction when the cleaning tank is in the housing position. In addition, the second restricting portion of each guide section, which is located above the first restricting portion, restricts the widthwise displacement of the lid by contacting the side edge of the lid from the outside in the width direction when the lid is in the closed position.

[0016] On the other hand, in the lifting mechanism, when the washing tank moves from the storage position to the pull-out position, the contact part moves forward and separates from the lid, causing the biasing means to move the lid to the retracted position.

[0017] Thus, when positioning the lid in the width direction relative to the washing tank, this dishwasher uses guides having a first restricting section and a second restricting section to perform the positioning. As a result, even if there is play in the width direction of the washing tank, which is movably supported by the housing, this play is less likely to affect the width direction positioning of the lid relative to the washing tank.

[0018] As a result, this dishwasher can suppress the accumulation of errors compared to the conventional dishwasher described above, in which the washing tub and lid are positioned via the housing and each link.

[0019] Therefore, the dishwasher of the present invention can improve the positioning accuracy of the lid in the width direction relative to the washing tank.

[0020] The first regulating part preferably has a first inclined surface that faces the inner side in the width direction, is inclined inward and rearward in the width direction, and can contact the side wall of the washing tank when the washing tank moves from the drawn-out position to the storage position.

[0021] In this case, when the washing tank moves from the drawn-out position to the storage position, the first regulating part of each guide part makes it easier to guide the washing tank to an appropriate position in the width direction by the first inclined surface contacting the side wall of the washing tank. As a result, this dishwasher can further improve the positioning accuracy in the width direction of the lid with respect to the washing tank.

[0022] The side wall of the washing tank preferably has a first regulated part that can contact the first regulating part from the inner side in the width direction when the washing tank moves from the drawn-out position to the storage position. The first regulated part has a first part that contacts the first regulating part when the washing tank is in the storage position, and a tank inclined surface that is located behind the first part, faces the outer side in the width direction, and is inclined inward and rearward in the width direction, and can contact the first regulating part during the movement of the washing tank from the drawn-out position to the storage position.

[0023] In this case, when the washing tank moves from the drawn-out position to the storage position, the first regulating part of each guide part makes it easier to guide the washing tank to an appropriate position in the width direction by contacting the tank inclined surface of the first regulated part of the side wall. And when the washing tank is in the storage position, the first regulating part of each guide part can reliably regulate the displacement in the width direction of the washing tank by contacting the first part of the first regulated part. As a result, this dishwasher can further improve the positioning accuracy in the width direction of the lid with respect to the washing tank.

[0024] The second regulating part preferably has a second inclined surface that faces the inner side in the width direction, is inclined outward and upward in the width direction, and can contact the side edge of the lid when the lid moves from the retracted position to the closed position.

[0025] In this case, when the lid moves from the retracted position to the closed position, the second restricting portion of each guide part makes it easier to guide the lid to the appropriate position in the width direction by having the second inclined surface abut against the side edge of the lid. As a result, this dishwasher can further improve the positioning accuracy of the lid in the width direction relative to the washing tank.

[0026] The second restricting portion preferably has a third inclined surface that faces inward in the width direction and is inclined inward and rearward in the width direction, and that can abut against the side edge of the lid when the lid moves from the retracted position to the closed position.

[0027] In this case, when the lid moves from the retracted position to the closed position, the second regulating portion of each guide part makes it easier to guide the lid to the appropriate position in the width direction by having the third inclined surface abut against the side edge of the lid. As a result, this dishwasher can further improve the positioning accuracy of the lid in the width direction relative to the washing tank.

[0028] The side edge of the lid preferably has a second restricted portion that can contact the second restricted portion from the inside in the width direction when the lid moves from the retracted position to the closed position. Furthermore, the second restricted portion preferably has a second portion that contacts the second restricted portion when the lid is in the closed position, and a lid inclined surface located below the second portion, facing outward in the width direction and inclined inward and downward in the width direction, which can contact the second restricted portion while the lid is moving from the retracted position to the closed position.

[0029] In this case, when the lid moves from the retracted position to the closed position, the second restricting portion of each guide unit contacts the inclined surface of the second restricted portion of the lid, making it easier to guide the lid to the appropriate position in the width direction. Then, when the lid is in the closed position, the second restricting portion of each guide unit contacts the second portion of the second restricted portion, thereby reliably restricting the lid's positional displacement in the width direction. As a result, this dishwasher can further improve the positioning accuracy of the lid in the width direction relative to the washing tank. [Effects of the Invention]

[0030] According to the dishwasher of the present invention, the positioning accuracy of the lid in the width direction relative to the washing tank can be improved. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0032] The following describes embodiments of the present invention with reference to the drawings.

[0033] (Examples) As shown in Figure 1, the dishwasher 1 of the embodiment is an example of a specific embodiment of the dishwasher of the present invention. The dishwasher 1 is a front-pull type installed below the countertop CT1 of a system kitchen.

[0034] In this embodiment, the side facing the casing 9 when a user of the system kitchen is using it, i.e., the left side of Figure 1, is defined as the front of the casing 9, and the opposite side, the right side of Figure 1, is defined as the rear of the casing 9. Furthermore, the side to the left when the user is facing the casing 9, i.e., the far side of Figure 1, is defined as the left side of the casing 9, and the side to the right, i.e., the near side of Figure 1, is defined as the right side of the casing 9. The front-to-back, left-to-right, and up-and-down directions shown in Figures 2 and beyond all correspond to those in Figure 1. In this embodiment, the width direction of the dishwasher 1 is the left-to-right direction.

[0035] <Housing, washing tank, and lid> The dishwasher 1 comprises a housing 9, a washing tank 7, and a lid 8.

[0036] The enclosure 9 is roughly box-shaped. The top of the enclosure 9 is covered by the top plate CT1. The enclosure 9 has an enclosure opening 9H. The enclosure opening 9H opens up a wide area from the top to the bottom of the front of the enclosure 9. The enclosure opening 9H connects the inside of the enclosure 9 to the outside.

[0037] The cleaning tank 7 is housed within the housing 9. The position of the cleaning tank 7 shown in Figure 1 is considered its housing position. When the cleaning tank 7 is in its housing position, the housing opening 9H is closed.

[0038] The washing tank 7 is roughly box-shaped. In this embodiment, the washing tank 7 is a resin molded product that has heat resistance in the temperature range of heated washing water and heated air used for drying.

[0039] A slide rail mechanism (not shown) is positioned between the cleaning tank 7 and the housing 9. As shown in Figure 2, the cleaning tank 7 can slide in the front-rear direction relative to the housing 9 by this slide rail mechanism.

[0040] As shown in Figures 3 and 4, the cleaning tank 7 has a tank opening 7H. The top of the cleaning tank 7 is open through the tank opening 7H. The cleaning tank 7 also has an annular periphery 7E surrounding the tank opening 7H.

[0041] A resin cover member 77 is fitted to the portion of the washing tank 7 located between its front and upper ends and the peripheral edge 7E. The rear edge of the cover member 77 is adjacent to the front edge of the peripheral edge 7E.

[0042] As shown in Figure 1, a handle 7G is provided at the upper front end of the cleaning tank 7. By grasping the handle 7G and manually sliding the cleaning tank 7 from the storage position shown in Figure 1 to the front of the housing 9, the cleaning tank 7 moves to a pull-out position where it is exposed to the outside of the housing 9 through the housing opening 9H, as shown in Figure 2. Furthermore, by manually sliding the cleaning tank 7 from the pull-out position shown in Figure 2 to the rear of the housing 9, the cleaning tank 7 returns to the storage position shown in Figure 1.

[0043] As shown in Figure 2, with the washing tank 7 moved to the pull-out position, the user can place the tableware TW1 into or remove it from the washing tank 7 through the tank opening 7H.

[0044] Tableware TW1 includes, for example, bowls, plates, glasses and other eating and drinking utensils, as well as chopsticks, spoons, forks, etc. Tableware TW1 is an example of the "items to be washed" in this invention.

[0045] As shown in Figure 1, a water reservoir 71 is provided at the bottom of the washing tank 7, capable of storing washing water for washing the tableware TW1. A dish basket 70 is also placed inside the washing tank 7. The tableware TW1 is placed on the dish basket 70.

[0046] As shown in Figures 1 and 2, the lid 8 is positioned at the top of the housing 9. As shown in Figures 5 and 6, the lid 8 is a roughly rectangular flat plate with reinforcing ribs and protrusions. In this embodiment, the lid 8, like the washing tank 7, is a resin molded product that has heat resistance in the temperature range of heated washing water and heated air used for drying.

[0047] Reinforcement frames 8W1, 8W2, and 8W3 are located on the left and right side edges 8S and the front edge of the cover 8. Reinforcement frames 8W1 to 8W3 are steel plates bent into a roughly U-shape in cross-section. Reinforcement frames 8W1 to 8W3 reinforce the cover 8 to suppress deformation such as warping and twisting.

[0048] As shown in Figure 5, a sealing member 80 is provided on the lower surface of the lid 8. The upper part of the sealing member 80 is fitted into fitting grooves recessed in the left and right side edges 8S, the front edge, and the rear edge of the lid 8, and is held in place by reinforcing frames 8W1 to 8W3 to prevent it from coming out of the fitting grooves.

[0049] The sealing member 80 is annular in shape and conforms to the peripheral edge 7E surrounding the tank opening 7H in the washing tank 7. The sealing member 80 is made of an elastic material such as rubber or a closed-cell foam.

[0050] The lower portion of the sealing member 80 is, for example, an annular cross-section, and is easily deformed to expand horizontally while being compressed vertically when it comes into contact with the peripheral edge 7E surrounding the tank opening 7H.

[0051] As shown in Figure 1, the lid 8 is in a closed position that closes the tank opening 7H when the washing tank 7 is in the housing position. At this time, the sealing member 80 seals the gap between the peripheral edge 7E surrounding the tank opening 7H and the lid 8 in the closed position. In Figure 3, the area E1 on the peripheral edge 7E that the sealing member 80 contacts is shown with shading.

[0052] The lid 8 is movable between a closed position as shown in Figure 1 and a retracted position as shown in Figure 2, which is the uppermost and forwardmost position within the housing 9 from the closed position, opening the tank opening 7H.

[0053] <Lifting mechanism> As shown in Figures 1 and 2, the dishwasher 1 is further equipped with a lifting mechanism 5. The lifting mechanism 5 moves in conjunction with the movement of the washing tub 7 between the storage position shown in Figure 1 and the unfolded position shown in Figure 2, as will be explained in detail below, and moves the lid 8 between the closed position shown in Figure 1 and the retracted position shown in Figure 2.

[0054] The lifting mechanism 5 includes a tension coil spring 59 shown in Figures 1, 2, and 6, a guided projection 85 shown in Figures 5 to 8 and 10 to 12, a guide part 50 shown in Figures 7 to 9 and 11 to 15, and a cam part 57 shown in Figures 4, 8, 10, and 13. The tension coil spring 59 is an example of the "biasing means" of the present invention.

[0055] Furthermore, the lifting mechanism 5 has a contact portion 78 shown in Figures 3, 4, 7, 8, 11, and 12, and a contacted portion 88 shown in Figures 5 to 8, 11, and 12.

[0056] <Tension coil spring> As shown in Figure 6, a pair of tension coil springs 59 are provided on the left side edge 8S of the lid 8 and on the right side edge 8S of the lid 8. The rear end of each tension coil spring 59 is locked to locking pieces 8W1A and 8W2A which are protruding from the intermediate parts of the reinforcing frames 8W1 and 8W2.

[0057] As shown in Figures 1 and 2, the front end of each tension coil spring 59 is locked to the front end of the upper wall of the housing 9. Each tension coil spring 59 is provided between the housing 9 and the lid 8, biasing the lid 8 forward toward the retracted position shown in Figure 2.

[0058] <Guided protrusion> As shown in Figure 5, two pairs of guided projections 85 are provided on the front and rear ends of the left and right side edges 8S of the cover 8. Each guided projection 85 is a roughly cylindrical metal member. The tip of each guided projection 85 is widened in a flange shape to prevent it from coming off.

[0059] A pair of guided protrusions 85 located at the front are fastened to the front ends of the reinforcing frames 8W1 and 8W2 and protrude outward in the width direction so as to be spaced apart from each other from the left and right side edges 8S of the cover 8. A pair of guided protrusions 85 located at the rear are fastened to the rear ends of the reinforcing frames 8W1 and 8W2 and protrude outward in the width direction so as to be spaced apart from each other from the left and right side edges 8S of the cover 8.

[0060] <Information Department> As shown in Figure 7, the guide portion 50 is supported on the inner wall surface 9W of the side wall 9S of the housing 9 so as to correspond one-to-one with each guided protrusion 85. The guide portion 50 is positioned between the side wall 9S of the housing 9 and the left and right side edges 8S of the lid 8. In Figure 8, the side wall 9S of the housing 9 is not shown, but the side wall 9S is located on the near side of the page relative to the guide portion 50.

[0061] The guide section 50 is provided in pairs corresponding to a pair of guided projections 85 located at the front, and also in pairs corresponding to a pair of guided projections 85 located at the rear.

[0062] Figures 7 and 8 show the guide section 50 located at the front and right within the housing 9. Figures 11 and 12 show a pair of guide sections 50 located at the front and left and right within the housing 9. Figures 13 to 15 show the guide section 50 located at the rear and right within the housing 9. The same applies to the guide section 50 located at the rear and left within the housing 9, so its illustration is omitted.

[0063] The support shaft 50X shown in Figure 8 is a multi-stage cylinder that extends short in the width direction, and its outer end in the width direction is fastened to the side wall 9S of the housing 9. The restricting piece 9S1 shown by the dashed line in Figure 8 is a small piece cut out from the side wall 9S so as to protrude inward in the width direction. The restricting edge 9S2 shown by the dashed line in Figure 8 is part of the periphery of the notch used to cut out the restricting piece 9S1.

[0064] The guide portion 50 is externally fitted onto the support shaft 50X and is supported on the inner wall surface 9W of the side wall 9S by being restricted from coming off the support shaft 50X by a restricting piece 9S1 and a restricting edge 9S2 that engage with the rear portion.

[0065] In this embodiment, the guide portion 50 is a resin molded product and integrally has a protrusion 51T and a pair of deformable portions 51U and 51D.

[0066] As shown in Figures 8 and 9, the protrusion 51T is a cylinder that projects inward in the width direction from the lower end of the guide portion 50. The pair of deformable portions 51U and 51D are each approximately U-shaped. As shown in Figure 8, they sandwich the restricting piece 9S1 in the vertical direction.

[0067] The guide section 50 can swing within a small angular range around the support shaft 50X due to the elastic deformation of the deformable sections 51U and 51D.

[0068] As shown in Figures 7 to 9, a guide groove 58 is formed in the upper part of the guide portion 50. The guide groove 58 extends backward sloping downward from the front end 58F, and further extends backward so that the downward sloping angle gradually decreases until it is approximately horizontal. As shown in Figures 7 and 8, the guide groove 58 accommodates the guided projection 85.

[0069] As the lid 8 moves between the closed position shown in Figure 1 and the retracted position shown in Figure 2, the guided projection 85 slides along the guide groove 58. The position of the lid 8 shown in Figures 7 and 8 is the closed position, where the guided projection 85 is moved rearward from the front end 58F of the guide groove 58. The position of the washing tank 7 shown in Figures 7 and 8 is the storage position.

[0070] The position of the lid 8 shown in Figure 10 is the closed position, and the position of the washing tank 7 shown in Figure 10 is the storage position.

[0071] The position of the lid 8 shown in Figures 11 and 12 is the retracted position, where the lid 8 is biased by each tension coil spring 59 and the guided projection 85 is stopped in contact with the front end 58F of the guide groove 58. The state of the washing tank 7 shown in Figures 11 and 12 is a transient state in which it is moving from the pull-out position to the storage position.

[0072] <Cam section> As shown in Figures 4, 8, 10, and 13, the cam portion 57 is integrally formed on the left and right side walls 7S of the cleaning tank 7 so as to correspond one-to-one with each guide portion 50. The cam portion 57 is composed of ribs that protrude outward in the width direction from the left and right side walls 7S of the cleaning tank 7.

[0073] The cam portion 57 is provided in pairs corresponding to a pair of guide portions 50 located at the front, and also in pairs corresponding to a pair of guide portions 50 located at the rear.

[0074] Figures 4 and 8 show the cam portion 57 located in the front part of the right side wall 7S of the cleaning tank 7. Figures 10 and 13 show the cam portion 57 located in the rear part of the right side wall 7S of the cleaning tank 7. The same applies to the two cam portions 57 located in the front and rear parts of the right side wall 7S of the cleaning tank 7, so their illustration is omitted.

[0075] The lower surface of the cam portion 57 slopes downward from the rear end toward the front, and then extends horizontally toward the front. When the cleaning tank 7 moves from the pull-out position shown in Figure 2 toward the storage position shown in Figure 1, and the lid 8 is pressed backward by the pair of contact portions 78 of the cleaning tank 7 as will be described later, each guided projection 85 slides along each guide groove 58 so as to slope downward toward the rear. As a result, the lid 8 descends and the sealing member 80 comes into contact with the periphery 7E of the cleaning tank 7.

[0076] In this case, as shown in Figures 8 and 13(c), the lower surface of the cam portion 57 contacts the outer circumferential surface of the convex portion 51T of the guide portion 50 from above. As a result, the guide portion 50 can reliably resist the restoring force when the sealing member 80 is compressed and deformed. Consequently, when the cleaning tank 7 reaches the storage position, the sealing member 80 can reliably seal the gap between the peripheral edge 7E surrounding the tank opening 7H and the lid 8 in the closed position.

[0077] <Contact part> As shown in Figures 4 and 11, a pair of contact portions 78 are provided in the cleaning tank 7. The contact portions 78 are integrally formed with the peripheral edge 7E surrounding the tank opening 7H in the cleaning tank 7.

[0078] The left contact portion 78 protrudes upward from a position forward and to the left of the tank opening 7H on the peripheral edge 7E. The right contact portion 78 protrudes upward from a position forward and to the right of the tank opening 7H on the peripheral edge 7E. The rearward-facing surface of each contact portion 78 is a flat surface extending in the vertical and width directions.

[0079] A pair of reinforcing protrusions 77A are integrally formed on the cover member 77. The left reinforcing protrusion 77A protrudes upward from the rear and left corner of the cover member 77 and abuts against the left contact portion 78 from the front, reinforcing the left contact portion 78. The right reinforcing protrusion 77A protrudes upward from the rear and right corner of the cover member 77 and abuts against the right contact portion 78 from the front, reinforcing the right contact portion 78.

[0080] <Abutted part> As shown in Figures 6 and 11, a pair of contact portions 88 are provided on the lid 8. The left contact portion 88 is recessed at the front and left corner of the lid 8, corresponding to the left contact portion 78. The right contact portion 88 is recessed at the front and right corner of the lid 8, corresponding to the right contact portion 78.

[0081] The forward-facing surface of each contact portion 88 is a flat surface that extends vertically and horizontally so as to be able to contact each contact portion 78.

[0082] As shown in Figure 11, during the transient state in which the washing tank 7 moves from the pull-out position to the storage position, each contact portion 78 approaches each contacted portion 88.

[0083] When the cleaning tank 7 moves further toward the storage position from the state shown in Figure 11 to the state shown in Figure 12, the rearward-facing surface of each contact portion 78 comes into contact with the forward-facing surface of each contacted portion 88, thereby restricting the front-to-back position of the lid 8 relative to the cleaning tank 7.

[0084] In this state, a sufficient gap is ensured between the inward-facing surface in the width direction of each contact portion 78 and the inclined surface adjacent to each contacted portion 88 in the width direction.

[0085] Subsequently, each contact portion 78 effectively becomes a pressing portion that pushes the lid 8 backward, moving the lid 8 to the closed position shown in Figure 1 against each tension coil spring 59.

[0086] <First Regulatory Department, Second Regulatory Department, First Regulated Department, and Second Regulated Department> The dishwasher 1 has the following configuration to improve the positioning accuracy of the lid 8 in the width direction relative to the washing tank 7 when the washing tank 7 moves to the pull-out position shown in Figure 2 and the lid 8 moves to the retracted position shown in Figure 2 in conjunction with this movement.

[0087] Each guide section 50 has a first regulating section 100 shown in Figures 8, 9, 13, and 14, and a second regulating section 200 shown in Figures 7, 9, 13, and 15.

[0088] The side wall 7S of the washing tank 7 has a first restricted portion 110 as shown in Figures 8, 10, 13, and 14. The left and right side edges 8S of the lid 8 have a second restricted portion 220 as shown in Figures 8, 10, 13, and 15.

[0089] As shown in Figure 9, the first restricting portion 100 is formed at the inner end in the width direction of the protrusion 51T of each guide portion 50. The first restricting portion 100 has a first inclined surface 101. The first inclined surface 101 faces inward in the width direction and is inclined inward and backward in the width direction.

[0090] The second restricting portion 200 is located above the first restricting portion 100 in each guide portion 50 and is formed in a portion facing inward in the width direction. The second restricting portion 200 has a second inclined surface 202 and a third inclined surface 203.

[0091] The second inclined surface 202 is located above and behind the rear end of the guide groove 58, and is inclined outward and upward in the width direction, facing inward in the width direction. The second inclined surface 202 has a roughly right-angled triangular shape, with a first side extending in the front-rear direction above, a second side connecting to the rear end of the first side and perpendicular to the first side, extending inward and downward in the width direction, and a hypotenuse connecting the front end of the first side and the lower end of the second side.

[0092] The third inclined surface 203 connects to the hypotenuse of the second inclined surface 202 and extends downward from the second inclined surface 202. The lower portion of the third inclined surface 203 is located behind the rear end of the guide groove 58. The third inclined surface 203 faces inward in the width direction and is inclined inward and rearward in the width direction. The third inclined surface 203 is approximately trapezoidal in shape.

[0093] As shown in Figures 8, 10, 13, and 14, the first restricted portion 110 is integrally formed with the side wall 7S of the cleaning tank 7 so as to correspond one-to-one with the first restricted portion 100 of each guide portion 50. The first restricted portion 110 has a rib 110R that protrudes outward in the width direction from the side wall 7S of the cleaning tank 7 and extends in the front-rear direction.

[0094] The first restricted sections 110 are provided in pairs corresponding to the first restricted sections 100 of the pair of guide sections 50 located at the front, and also in pairs corresponding to the first restricted sections 100 of the pair of guide sections 50 located at the rear.

[0095] Figure 8 shows the first restricted portion 110 located in the front part of the right side wall 7S of the cleaning tank 7. Figures 10, 13, and 14 show the first restricted portion 110 located in the rear part of the right side wall 7S of the cleaning tank 7. The same applies to the two first restricted portions 110 located in the front and rear parts of the left side wall 7S of the cleaning tank 7, so their illustration is omitted.

[0096] As shown in Figures 8 and 10, the first restricted portion 110 has a first part 111 and a tank inclined surface 115. The first part 111 is located in the middle of the rib 110R in the front-rear direction and, as shown in Figures 8, 13(c), and 14(c), is the part that abuts against the rear end of the first inclined surface 101 of the first restricted portion 100 when the washing tank 7 is in the housing position.

[0097] The first restricting section 100 restricts the positional displacement of the cleaning tank 7 in the width direction by having the rear end of the first inclined surface 101 abut against the side wall 7S of the cleaning tank 7 from the outside in the width direction, more specifically, against the first portion 111 of the first restricted section 110, when the cleaning tank 7 is in the housing position.

[0098] In this case, the rear end of the first inclined surface 101 does not necessarily come into contact with the first portion 111 of the first restricted portion 110, but may face the first portion 111 of the first restricted portion 110 with a small gap that is permitted in the design.

[0099] As shown in Figures 8 and 10, the tank inclined surface 115 is the rear end portion of the rib 110R and is located behind the first portion 111. The tank inclined surface 115 faces outward in the width direction and is inclined inward and rearward in the width direction.

[0100] As shown in Figures 14(a) and (b), the inclined surface 115 of the tank can contact the first inclined surface 101 of the first restricting section 100 from the inside in the width direction when the washing tank 7 is moving from the pull-out position to the storage position and there is a large displacement of the washing tank 7 in the width direction. The rib 110R can also contact the first inclined surface 101 of the first restricting section 100 from the inside in the width direction when the washing tank 7 is moving from the pull-out position to the storage position.

[0101] In other words, when the washing tank 7 moves from the pull-out position to the storage position, the first inclined surface 101 of the first restricting section 100 can come into contact with the tank inclined surface 115 and rib 110R of the first restricted section 110 from the outside in the width direction.

[0102] As shown in Figures 8, 10, 13, and 15, the second restricted portion 220 is formed on the reinforcing frames 8W1 and 8W2 of the left and right side edges 8S of the cover 8 so as to correspond one-to-one with the second restricted portion 200 of each guide portion 50.

[0103] The second restricted sections 220 are provided in pairs corresponding to the second restricted sections 200 of the pair of guide sections 50 located at the front, and also in pairs corresponding to the second restricted sections 200 of the pair of guide sections 50 located at the rear.

[0104] Figure 8 shows the second restricted portion 220 located on the front part of the right side edge 8S of the cover 8. Figures 10, 13, and 15 show the second restricted portion 220 located on the rear part of the right side edge 8S of the cover 8. The same applies to the two second restricted portions 220 located on the front and rear parts of the left side edge 8S of the cover 8, so their illustration is omitted.

[0105] As shown in Figures 8, 10, and 13, the second restricted portion 220 is located behind the guided projection 85 on the side edge 8S of the lid 8. The second restricted portion 220 has a second part 222 and a lid inclined surface 225. The second part 222 is the upper part of the side edge 8S of the lid 8, is a flat surface that extends vertically and in the front-rear direction and faces outward in the width direction, and as shown in Figures 13(c) and 15(c), is the part that abuts against the rear end of the third inclined surface 203 of the second restricted portion 200 when the lid 8 is in the closed position.

[0106] The second restricting portion 200 restricts the widthwise displacement of the lid 8 when the lid 8 is in the closed position by having the rear end of the third inclined surface 203 abut against the left and right side edges 8S of the lid 8 from the outside in the widthwise direction, more specifically against the second portion 222 of the second restricted portion 220.

[0107] In this case, the rear end of the third inclined surface 203 does not necessarily come into contact with the second portion 222 of the second restricted portion 220, but may face the second portion 222 of the second restricted portion 220 with a small gap that is permitted in the design.

[0108] As shown in Figures 8, 10, and 13, the lid inclined surface 225 is located below the second portion 222. The lid inclined surface 225 faces outward in the width direction and is inclined inward and downward in the width direction.

[0109] As shown in Figures 13(a) and (b), the lid inclined surface 225 can come into contact with the second inclined surface 202 of the second restricting portion 200 from the inside in the width direction when the lid 8 is moving from the retracted position to the closed position and there is a large displacement of the lid 8 in the width direction.

[0110] As shown in Figures 15(a) to (c), the third inclined surface 203 of the second restricting portion 200 can contact the left and right side edges 8S of the lid 8, more specifically, the inclined surface 225 and the second portion 222 of the second restricted portion 220 from the inside in the width direction, when the lid 8 moves from the retracted position to the closed position.

[0111] In other words, when the lid 8 moves from the retracted position to the closed position, the second inclined surface 202 and the third inclined surface 203 of the second restricting portion 200 can come into contact with the lid inclined surface 225 and the second portion 222 of the second restricted portion 220 from the outside in the width direction.

[0112] <Water supply pipes, water supply solenoid valves, drainage pipes, nozzles, and pumps> As shown in Figure 1, the dishwasher 1 further includes a water supply pipe P1, a water supply solenoid valve 69, a drain pipe P2, a nozzle 61, and a pump 62.

[0113] The water supply pipe P1 supplies water to the washing tank 7 from a water source (not shown) located outside the dishwasher 1. The water supply solenoid valve 69 opens and closes the water supply pipe P1 to switch the supply of water to the washing tank 7 on and off. The drain pipe P2 drains the washing water from the washing tank 7 to the outside of the dishwasher 1.

[0114] The nozzle 61 is located inside the cleaning tank 7. The pump 62 is assembled at the bottom of the water reservoir 71 of the cleaning tank 7.

[0115] The nozzle 61 is capable of spraying cleaning water into the cleaning tank 7 from multiple discharge holes. The spray direction of the nozzle 61 can be changed in various directions to ensure thorough cleaning of multiple stacked dishes TW1 in the cleaning tank 7, and to clean the inner wall surface of the cleaning tank 7 and the dish basket 70.

[0116] When the pump 62 is operating in the forward direction, it supplies the washing water stored in the water reservoir 71 of the washing tank 7 to the nozzle 61, causing it to be sprayed into the washing tank 7. The sprayed washing water is stored in the water reservoir 71 and is repeatedly supplied to the nozzle 61 by the pump 62. When the pump 62 is operating in the reverse direction, it drains the washing water in the washing tank 7 to the outside of the dishwasher 1 via the food residue filter 67 and the drain pipe P2.

[0117] <Heater, temperature sensor, and drying fan> The dishwasher 1 further includes a heater 63, a temperature sensor 31, and a drying fan 68.

[0118] The heater 63 heats the cleaning water stored in the water reservoir 71 of the cleaning tank 7, or the air inside the cleaning tank 7. The temperature sensor 31 detects the temperature of the cleaning water stored in the water reservoir 71 of the cleaning tank 7, or the air inside the cleaning tank 7, near the heater 63.

[0119] The drying fan 68 rotates with the heater 63 activated, sending heated air into the washing tank 7 to dry the dishes TW1. The air sent into the washing tank 7 by the drying fan 68 is exhausted to the outside of the dishwasher 1 via an exhaust passage 79 that opens at the front of the washing tank 7 and communicates with the inside of the washing tank 7.

[0120] <Washing operation> In the dishwasher 1 configured as described above, when the user pulls out the washing tank 7 to the storage position shown in Figure 2 in order to place the dishes TW1 inside the washing tank 7, the lifting mechanism 5 moves the lid 8 to the retracted position shown in Figure 2 in conjunction with the movement of the washing tank 7.

[0121] After the user places the tableware TW1 into the washing tank 7 and sets and starts the washing operation, the user pushes the washing tank 7 to the storage position shown in Figure 1, causing the lifting mechanism 5 to move the lid 8 to the closed position shown in Figure 1 in conjunction with the movement of the washing tank 7.

[0122] Then, the control unit (not shown) confirms, using sensors or the like, that the cleaning tank 7 is locked in the storage position and the tank opening 7H is closed by the lid 8, and then activates the pump 62 to perform a cleaning operation in which cleaning water is sprayed into the cleaning tank 7 from the nozzle 61.

[0123] During the washing operation, the control unit sequentially performs a washing process using washing water containing detergent and a rinsing process using clean washing water to thoroughly wash the dishes TW1 in the washing tank 7. At the end of the washing operation, the control unit performs a drying process, operating the heater 63 and drying fan 68 as appropriate to dry the dishes TW1 in the washing tank 7, and then terminates the washing operation.

[0124] <Effects and Effects> In the dishwasher 1 of this embodiment, when the washing tank 7 moves from the pull-out position shown in Figure 2 to the storage position shown in Figure 1, the lifting mechanism 5 enters a transient state as shown in Figures 11 and 12, bringing each contact portion 78 of the washing tank 7 closer to each contact portion 88 of the lid 8.

[0125] Then, as shown in Figure 12, the lifting mechanism 5 restricts the front-to-back position of the lid 8 relative to the cleaning tank 7 by having each contact portion 78 of the cleaning tank 7 come into contact with each contacted portion 88 of the lid 8.

[0126] Next, each contact portion 78 acts as a pressing portion that substantially presses the lid 8 backward, moving the lid 8 to the closed position shown in Figure 1 against each tension coil spring 59. At this time, each guide portion 50 slides the guided protrusion 85 backward and downward along the guide groove 58, so that the lid 8 can be moved to the closed position with high reliability.

[0127] Then, as shown in Figures 13(c) and 14(c), the first restricting portion 100 of each guide portion 50 restricts the positional displacement of the cleaning tank 7 in the width direction by having the rear end of the first inclined surface 101 abut against the side wall 7S of the cleaning tank 7 from the outside in the width direction, more specifically against the first portion 111 of the first restricted portion 110, when the cleaning tank 7 is in the housing position.

[0128] Furthermore, as shown in Figures 13(c) and 15(c), the second restricting portion 200, located above the first restricting portion 100 in each guide portion 50, restricts the widthwise displacement of the lid 8 when the lid 8 is in the closed position, by the rear end of the third inclined surface 203 contacting the left and right side edges 8S of the lid 8 from the outside in the widthwise direction, more specifically, the second portion 222 of the second restricted portion 220.

[0129] On the other hand, when the washing tank 7 moves from the storage position shown in Figure 1 to the pull-out position shown in Figure 2, the lifting mechanism 5 causes each contact portion 78 to move forward and separate from each contacted portion 88 of the lid 8, thereby moving each tension coil spring 59 to the retracted position shown in Figure 2.

[0130] Thus, when positioning the lid 8 in the width direction relative to the washing tank 7, the dishwasher 1 uses the guide sections 50, each having a first restricting section 100 and a second restricting section 200, to perform the positioning. As a result, even if there is play in the width direction of the washing tank 7, which is movably supported by the housing 9, this play is less likely to affect the width direction positioning of the lid 8 relative to the washing tank 7.

[0131] As a result, this dishwasher 1 can suppress the accumulation of errors compared to the conventional dishwasher described above, in which the washing tank and lid are positioned via the housing and each link.

[0132] Therefore, the dishwasher 1 of this embodiment can improve the positioning accuracy of the lid 8 in the width direction relative to the washing tank 7. As a result, when the washing tank 7 reaches the storage position, the dishwasher 1 can reliably seal the gap between the peripheral edge 7E surrounding the tank opening 7H and the lid 8 in the closed position with the sealing member 80 which precisely contacts the region E1 shown in Figure 3, thereby reliably suppressing water leakage from that gap. Furthermore, even if bending or deformation occurs in the washing tank 7 or the lid 8 due to aging, the sealing member 80 can absorb that bending or deformation to some extent, so that the state of sealing the gap between the peripheral edge 7E surrounding the tank opening 7H and the lid 8 in the closed position can be stably maintained over a long period of time.

[0133] Furthermore, in this dishwasher 1, as shown in Figures 13 and 14, the first restricting portion 100 has a first inclined surface 101. With this configuration, when the washing tank 7 moves from the pull-out position to the storage position, the first restricting portion 100 of each guide portion 50 makes it easier to guide the washing tank 7 to the appropriate position in the width direction by having the first inclined surface 101 come into contact with the first restricted portion 110 formed on the side wall 7S of the washing tank 7. As a result, this dishwasher 1 can further improve the positioning accuracy of the lid 8 in the width direction relative to the washing tank 7.

[0134] Furthermore, in this dishwasher 1, the first restricted portion 110 has a first part 111 and a tub inclined surface 115. With this configuration, when the washing tub 7 moves from the pull-out position to the storage position, the first restricted portion 100 of each guide portion 50 makes it easier to guide the washing tub 7 to the appropriate position in the width direction by having the first inclined surface 101 abut against the tub inclined surface 115 of the first restricted portion 110. When the washing tub 7 is in the storage position, the first restricted portion 100 of each guide portion 50 has the rear end of the first inclined surface 101 abut against the first part 111 of the first restricted portion 110, thereby reliably restricting the positional displacement of the washing tub 7 in the width direction. As a result, this dishwasher 1 can further improve the positioning accuracy of the lid 8 in the width direction relative to the washing tub 7.

[0135] Furthermore, in this dishwasher 1, as shown in Figures 13 and 15, the second restricting portion 200 has a second inclined surface 202 and a third inclined surface 203. With this configuration, when the lid 8 moves from the retracted position to the closed position, the second restricting portion 200 of each guide portion 50 makes it easier to guide the lid 8 to the appropriate position in the width direction by having the second inclined surface 202 and the third inclined surface 203 contact the second restricted portion 220 formed on the left and right side edges 8S of the lid 8. As a result, this dishwasher 1 can further improve the positioning accuracy of the lid 8 in the width direction relative to the washing tank 7.

[0136] Furthermore, in this dishwasher 1, the second restricted portion 220 has a second portion 222 and a lid inclined surface 225. With this configuration, when the lid 8 moves from the retracted position to the closed position, the second restricting portion 200 of each guide portion 50 makes it easier to guide the lid 8 to the appropriate position in the width direction by having the second inclined surface 202 and the third inclined surface 203 come into contact with the lid inclined surface 225 and the second portion 222 of the second restricted portion 220. When the lid 8 is in the closed position, the rear end of the third inclined surface 203 of each guide portion 50 comes into contact with the second portion 222 of the second restricted portion 220, thereby reliably restricting the positional displacement of the lid 8 in the width direction. As a result, this dishwasher 1 can further improve the positioning accuracy of the lid 8 in the width direction relative to the washing tank 7.

[0137] Although the present invention has been described above with reference to examples, it goes without saying that the present invention is not limited to the above examples and can be applied with appropriate modifications without departing from its spirit.

[0138] In the embodiment, the lifting mechanism 5 has two pairs of guide sections 50, each having a first restricting section 100 and a second restricting section 200. However, the present invention is not limited to this configuration. For example, in the embodiment, the first restricting section 100 and the second restricting section 200 are removed from a pair of guide sections 50 located in the front or rear, and the lifting mechanism 5 is modified to have one pair of guide sections 50 having the first restricting section 100 and the second restricting section 200. Furthermore, in the embodiment, the pair of guided protrusions 85 located in the front or rear and the pair of guide sections 50 are removed, and the remaining pair of guided protrusions 85 and the pair of guide sections 50 are modified to appropriately adjust their front-to-back position within the housing 9.

[0139] In this embodiment, the first restricting portion 100 has a protruding shape, but the present invention is not limited to this configuration, and any shape is acceptable, such as a non-protruding sliding surface. The same applies to the second restricting portion 200 and the first restricted portion 110.

[0140] In this embodiment, the second restricted portion 220 is a non-protruding sliding surface, but the present invention is not limited to this configuration, and may have any shape, such as a protruding convex portion or rib. [Industrial applicability]

[0141] The present invention can be used, for example, in dishwashers, dishwasher-dryers with drying functions, or kitchen equipment. [Explanation of Symbols]
