Description

dishwasher

The present invention relates to a built-in type dishwasher that cleans dishes by spraying washing water from the washing nozzle toward the dishes.

The configuration of the conventional dishwasher 100 will be described.

FIG. 6 is a side view showing an internal configuration of a conventional dishwasher 100, and FIG. 7 is a front view thereof. As shown in FIGS. 6 and 7, the dishwasher 100 is housed in a system kitchen, and includes a washing tub 102 inside a metal casing 101 having an opening on the front side.

The washing tank 102 has an opening 102a on the upper side, and a washing basket 104 for storing tableware 103 is disposed therein. A cleaning nozzle 105 is rotatably provided below the cleaning basket 104, and cleaning water accumulated in the cleaning tank 102 is circulated by the cleaning pump 106 and sprayed from the cleaning nozzle 105 to clean the dishes 103. .

Further, a slide mechanism 107 composed of a rail or the like is fixed to the side of the cleaning tank 102, and the cleaning tank 102 is supported so as to be movable in the front-rear direction.

When the tableware 103 is taken in and out, the user pulls the cleaning tank 102 forward from the housing 101 and accommodates the tableware 103 from the opening 102a. Next, the user returns the cleaning tank 102 to the housing 101 and stores it. At the same time, the lid 108 that has been waiting in the upper space in the housing 101 moves downward while moving downward by the link mechanism 109 or the like disposed on the inner surface of the housing 101, and opens the opening 102 a of the cleaning tank 102. Occlude.

The metal casing 101 is made of a thin rolled steel plate. The rail holding portion 101a is formed by performing step pressing on the left and right side walls of the housing 101. The rail holding unit 101a holds the washing tank 102 containing the tableware 103 via the slide mechanism 107 (see, for example, Patent Document 1).

However, as the dishwasher 100 becomes larger, the quantity of tableware that can be accommodated increases. In the conventional configuration, when the weight of the cleaning tank 102 increases, the conventional casing 101 lacks the strength of the portion that supports the cleaning tank 102 via the slide mechanism 107. For this reason, there exists a possibility that the washing tank 102 moves below and the watertightness of the part which obstruct | occludes the opening part 102a above the washing tank 102 with the cover body 108 may fall. Although it is necessary to reinforce the portion that supports the cleaning tank 102, there is a problem that if the thickness of the housing 101 is increased, the cost increases.

Also, there is a limit to the depth of the step pressing process on the side wall of the casing 101. By deepening the stepping, there is a problem that processing becomes difficult or deformation easily occurs, and the function as the outer structure is impaired.

It is a front view which shows the detailed structure of the part which supports the washing tank 11 of.

As shown in FIGS. 1 to 3, the dishwasher 50 is provided with a washing tub 11 that houses tableware 3 that is an object to be cleaned, and is housed in a metal housing 10 that has an opening in the front. I have. The cleaning tank 11 has an opening 11a on the upper side.

The washing tank 11 is held movably in the front-rear direction by a slide mechanism 12 fixed below both sides, and the slide mechanism 12 is supported by rail mounting members 13 provided inside the left and right side walls 10a of the housing 10. It is supported.

The slide mechanism 12 has a fixed rail portion 12 a fixed to the rail mounting member 13 and a movable rail portion 12 b fixed to the cleaning tank 11. Between the fixed rail portion 12a and the movable rail portion 12b, the movable rail portion 12b is moved in the longitudinal direction with respect to the fixed rail portion 12a by the plurality of rolling elements 30 (in the front-rear direction in a state where it is incorporated in the dishwasher 50). ) Can be moved.

When the tableware 3 is taken in and out, the user pulls the cleaning tank 11 forward from the housing 10 and accommodates or takes out the tableware 3 from the opening 11a. Next, the user returns the cleaning tank 11 into the housing 10 and stores it. At the same time, the lid body 14 waiting in the upper space in the housing 10 is lowered while moving backward by the link mechanism 15 arranged on the inner surface of the housing 10. Then, the lid 14 closes the opening 11 a of the cleaning tank 11 in a watertight manner via a seal member 23 provided on the outer periphery of the inner surface of the lid 14.

The metal casing 10 is formed by integrally bending the left and right side walls 10a and the bottom surface 10f by bending a thin rolled steel sheet. A rail mounting member support portion 10b that protrudes inward is formed by performing step pressing (more specifically, louver processing in which the upper side is opened) at a plurality of positions at the same height on the left and right side walls 10a. Has been. The rail attachment member support portion 10b holds the cleaning tank 11 containing the tableware 3 from below via the rail attachment member 13 and the slide mechanism 12. It is assumed that the dishwasher 50 has a larger width and height than conventional ones.

The rail mounting member 13 is formed in a long shape so that the cross-section is substantially U-shaped (Greek character-shaped) by bending a thin rolled steel plate, which is the same as the housing 10. Is done. The rail attachment member 13 has a step portion 13 a located inside the housing 10 in a state of being attached to the side wall 10 a of the housing 10. The rail attachment member 13 is configured to have a rectangular or box-shaped cross section when attached to the housing 10.

A rail holding portion 13b that supports and holds the fixed rail portion 12a of the slide mechanism 12 from below is provided in a plurality of positions at the lowermost portion of the step portion 13a by step pressing (more specifically, louver processing in which the upper portion is opened). And projecting in the same direction.

The rail mounting member 13 has an upper flange portion 13c and a lower flange portion 13d on the upper side and the lower side of the substantially U-shaped section, respectively. The rail attachment member 13 is fixed to the side wall 10a of the housing 10 with several screws at the upper flange portion 13c and the lower flange portion 13d.

The upper mounting portion 10c facing the upper flange portion 13c of the side wall 10a of the housing 10 and the lower mounting portion 10d facing the lower flange portion 13d are each subjected to step pressing so as to cover almost the entire length in the depth direction. Indented inward. Thereby, the strength of the side wall 10a is improved.

Furthermore, the upper mounting portion 10c and the lower mounting portion 10d have a step in the degree of inward protrusion. That is, the upper mounting portion 10c is located inside the lower mounting portion 10d. In accordance with this, the rail mounting member 13 is configured such that the upper flange portion 13c is located inside the lower flange portion 13d.

Further, an outer convex portion 10e formed by not performing step pressing is provided between the upper mounting portion 10c and the lower mounting portion 10d. This outward convex portion 10e is also formed to protrude outward substantially over the entire length in the depth direction.

The cleaning tank 11 includes a resin cleaning tank member 16 constituting at least a side surface and a resin bottom constituent member 17 constituting at least a bottom part. The bottom component member 17 is formed in a bottomed tray shape, and a seal member 18 made of an elastic body such as rubber is disposed on the outer peripheral upper end portion 17a.

Further, a groove portion 17b opened upward for holding the seal member 18 is formed in an annular shape on the outer peripheral upper end portion 17a. Further, the bottom component 17 is unitized by mounting most of the electrical components and mechanism components necessary for controlling the operation of the dishwasher 50, such as the movable rail portion 12b of the slide mechanism 12, the cleaning nozzle 19, and the cleaning pump 20. Has been. Thereby, even if the washing tank member 16 having a changed size is attached to the bottom component member 17, it is configured to function as the dishwasher 50.

The front and rear left and right outer peripheral lower end portions 16a of the cleaning tank member 16 are respectively provided with seal ribs 16b that hold the seal member 18 from above and work together with the groove portion 17b of the bottom component member 17 to exhibit water tightness.

The outer peripheral upper end 17a of the bottom component member 17 and the outer peripheral lower end 16a of the cleaning tank member 16 are joined in the vertical direction. The joint portion is provided with a seal portion 21 including a groove portion 17b, a seal rib 16b, and a seal member 18, and is sealed in a watertight manner.

Further, the left and right side wall portions 16c of the cleaning tank member 16 extend downward so that the seal portion 21 covers the mounting position of the slide mechanism 12 from above in the width direction.

In addition, a cleaning basket 22 that houses the tableware 3 is disposed above the seal portion 21 in the cleaning tank 11. A cleaning nozzle 19 is rotatably disposed below the cleaning basket 22, and cleaning water stored in the cleaning tank 11 is circulated by the cleaning pump 20 and sprayed from the cleaning nozzle 19 to clean the dishes 3.

Next, the operation and action of the dishwasher 50 configured as described above will be described.

First, a method for assembling the cleaning tank 11 in the casing 10 so as to be movable in the front-rear direction will be described. As described above, since the rail mounting member 13 has a step in the width direction between the upper flange portion 13c and the lower flange portion 13d, a pair of symmetrical objects is prepared. The pair of slide mechanisms 12 that are also symmetrical to each other are positioned on the rail mounting member 13 by bringing the bottom surface of the fixed rail portion 12 a into contact with the upper end surface of the rail holding portion 13 b of the rail mounting member 13. In this state, the side surface of the fixed rail portion 12a is fixed to the step portion 13a of the rail mounting member 13 with a screw.

Next, the pair of left and right rail mounting members 13 to which the slide mechanism 12 is mounted are, with respect to the left and right side walls 10a of the housing 10, the upper flange portion 13c as the upper mounting portion 10c and the lower flange portion 13d as the lower mounting portion 10d. Then, fix the screws at multiple locations.

At this time, the inner surface of the upper surface of the rail mounting member 13 is screwed in a state of being placed on the upper end surface of the rail mounting member support portion 10b provided on the side wall 10a of the housing 10. Thereby, the slide mechanism 12 is positioned in the height direction. In this way, the left and right slide mechanisms 12 are attached to the left and right side walls 10 a of the housing 10.

On the other hand, the cleaning tank 11 is assembled as follows. The cleaning tank member 16 is inserted from above the bottom component member 17 on which the seal member 18 is set. Thereby, the engaging part 16d provided in the downward extending part of the side wall part 16c is temporarily deformed by its own elasticity. Then, the engaging hole 16e is engaged with the convex portion 17c provided in the bottom component member 17, the vertical direction is restricted, and the cleaning tank member 16 and the bottom component member 17 are combined and integrated, whereby the cleaning tank 11 is completed. To do. At this time, the seal rib 16b of the cleaning tank member 16 presses the seal member 18 from above and deforms it to a specified tightening position, and the seal portion 21 is formed to seal the joint portion with water.

Furthermore, the cleaning tank 11 that has been assembled is placed on the movable rail portion 12b of the left and right slide mechanisms 12 assembled to the housing 10, and the movable rail portion 12b is positioned with a screw or the like in a state in which the depth direction is positioned. Fix it. Accordingly, the cleaning tank 11 is supported so as to be movable in the front-rear direction with respect to the housing 10.

In this state, the rail mounting member 13 having a substantially U-shaped cross section and the side wall 10a of the housing 10 form a cross-sectional shape of a rectangle or a box. Furthermore, the outward convex part 10e is formed in the side wall 10a part whose cross-sectional shape is a rectangle or a box-shaped part. As a result, the portion of the side wall 10a of the housing 10 where the load of the cleaning tank 11 containing the tableware 3 is applied is reinforced in a limited and concentrated manner, and the downward deformation strength is improved. The movement down is suppressed.

As the built-in dishwasher 50 spreads in the market, the need for larger size is increasing. In order to cope with this, the dishwasher 50 needs to enlarge the outline or increase the capacity of the tableware 3 that can be stored in the washing tank 11. In the system kitchen, a predetermined space (for example, a width of 450 mm and a height of 800 mm) for securing the dishwasher 50 is secured. For this reason, when enlarging the dishwasher 50, first, the width of the outer shell is maximized in a predetermined space, and the height is made as high as possible. Furthermore, the capacity | capacitance is enlarged by making the width | variety and height of the washing tank 11 high in it.

The left and right side walls 10a of the casing 10 constituting the outer shell of the dishwasher 50 are formed by bending a thin rolled steel plate. The side wall 10a is required to have a strength sufficient to cope with an increase in the capacity of the tableware and an increase in the amount of washing water necessary to ensure the increased cleaning performance of the tableware 3 via the slide mechanism 12. become.

In the dishwasher 50, the rail attachment member 13 having a substantially U-shaped cross section is attached to the side wall 10a, and the cross sectional shape of the rail attachment member 13 and the side wall 10a of the housing 10 is rectangular or box-like. To form. Thereby, only the part required in order to support the washing tank 11 which increased the weight can be reinforced. Therefore, the strength against the load can be improved without incurring costs such as increasing the thickness of the rolled steel sheet.

At this time, due to the presence of the rail attachment member 13, the slide mechanism 12 is positioned inward with respect to the side wall 10a. However, the cleaning tank 11 raises the left and right side wall parts 16 c of the cleaning tank member 16 upward from the outermost periphery of the seal part 21. Thereby, since the internal capacity | capacitance above the seal | sticker part 21 is expanded and the washing basket 22 is arrange | positioned there, the capacity | capacitance of the tableware 3 to accommodate can be enlarged.

Further, since it is not necessary to forcefully perform a deep stepping process corresponding to the width of the rail mounting member 13 on the side wall 10a of the housing 10, there is no fear of distortion or breakage during molding. Thereby, while being able to process easily, the housing | casing 10 with the stable shape dimension can be obtained.

Moreover, the rail attachment member 13 can be formed by a simple process only of bending, and is configured such that the cross-sectional shape is rectangular or box-like when attached to the side wall 10a of the housing 10. Thereby, the structure which can ensure intensity | strength easily is realizable.

Further, the side portion of the rail attachment member 13 includes a rail holding portion 13b that protrudes inward in a state of being attached to the housing 10 and supports the slide mechanism 12 from below. Thus, the rail holding portion 13b and the upper mounting portion are not concentrated on the upper mounting portion 10c and the lower mounting portion 10d of the side wall 10a of the housing 10 which is fixed with screws. 10c and the lower mounting portion 10d. Therefore, the structure of the attachment part by screw fixation can be simplified.

Further, the mounting height position of the rail mounting member 13 is determined on the housing 10 and rail mounting member support portions 10b for supporting the rail mounting member 13 from below are provided so as to protrude inward from the left and right side walls 10a. Yes. Thereby, the dispersion | variation in the height position of the slide mechanism 12 on either side can be reduced, and the movement to the front-back direction of the washing tank 11 can be made smooth. Moreover, the load of the washing tank 11 which accommodated the tableware 3 is supported by the upper end surface of the rail attachment member support part 10b, and the downward deformation | transformation of the rail attachment member 13 is suppressed. Thereby, the downward movement of the cleaning tank 11 can be suppressed, and the water-tightness of the part where the opening 11a above the cleaning tank 11 is closed by the lid 14 can be ensured.

Furthermore, since the load of the washing tank 11 containing the tableware 3 can be distributed to the rail attachment member support portion 10b, the upper attachment portion 10c, and the lower attachment portion 10d, the structure of the attachment portion by screw fixing is simplified. Can be

Further, the upper mounting portion 10c and the lower mounting portion 10d formed by projecting inwardly on the left and right side walls 10a of the housing 10 have a step difference in the degree of inward projection. Thereby, the part which attaches the rail attachment member 13 of the side wall 10a of the housing | casing 10 can be reinforced effectively by a simple process intensively and without incurring cost.

Further, on the left and right side walls 10a of the housing 10, between the upper mounting portion 10c and the lower mounting portion 10d, an outward convex portion 10e that protrudes outward from the upper mounting portion 10c and the lower mounting portion 10d is provided. ing. As a result, the rail mounting member 13 on the side wall 10a of the housing 10 and the portion of which the cross-sectional shape is formed in a rectangular or box shape can be reinforced in a concentrated manner with simple processing.

Note that a plurality of rail attachment member support portions 10b formed on the left and right side walls 10a and a rail holding portion 13b formed at the bottom of the step portion 13a of the rail attachment member 13 are provided in the depth direction of the dishwasher 50. It has been. However, you may form at least one of the rail attachment member support part 10b and the rail holding | maintenance part 13b as one protrusion part long in a depth direction. In particular, if the rail attachment member support portion 10b is formed as a single projecting portion that is long in the depth direction, the downward deformation of the upper surface of the rail attachment member 13 due to the load of the cleaning tank 11 containing the tableware 3 is suppressed. The effect can be increased.

Furthermore, the dishwasher 50 is configured by dividing the washing tub 11 into a washing tub member 16 and a bottom component 17. Further, most of the electrical parts and mechanism parts are mounted on the bottom component member 17 to form a unit. Thereby, even if a single thing is used as the bottom part component member 17 by enlarging or downsizing the portion above the seal portion 21 of the cleaning tank member 16, a cleaning tank having a different capacity can be obtained. Can do. For this reason, it can respond easily to production of the dishwasher 50 from which washing tank capacity differs, and can improve manufacturing efficiency.

Here, further features of the dishwasher 50 according to the present embodiment will be described in comparison with other dishwashers 51 using the same bottom component 17.

FIG. 4 is a side view showing the internal configuration of another dishwasher 51 using the same bottom component 17 in the embodiment of the present invention, and FIG. It is a front view which shows a part. In addition, the thing of the same structure as the dishwasher 50, such as the bottom part structural member 17, attaches | subjects the same code | symbol and abbreviate | omits the description.

As shown in FIG. 4, the dishwasher 51 has a shallower washing tank depth than the above-described dishwasher 50, and stores kitchen utensils in the system kitchen space below the dishwasher 51. A drawer 25 is provided. Such a shallow dishwasher 51 and the above-described deep dishwasher 50 having a deep washing tank depth are prepared so that the user can select a favorite one when planning a system kitchen. To improve the usability of the system kitchen.

The deep dishwasher 50 is characterized by the fact that the amount of tableware 3 that can be accommodated in the washing tub 11 is large. Therefore, as compared with the shallow dishwasher 51, not only the depth is deep but also the width dimension is required to be as wide as possible. Both the width dimension of the housing 10 and the width dimension of the washing tub 11 are set wider than the shallow dishwasher 51.

Specifically, as shown in FIG. 3, the dishwasher 50 raises the left and right side wall portions 16 c of the cleaning tub member 16 upward from the outermost periphery of the seal portion 21, thereby enabling the width dimension of the cleaning tub 11. It is as big as possible. As a result, the internal volume of the cleaning tank 11 is maximized. At the time of use, it is necessary to close the opening 11 a at the top of the cleaning tank member 16 for taking in and out the dishes 3 with the lid 14.

At this time, it is necessary to realize the convenience of taking in and out the tableware 3 and the resin moldability of the washing tank member 16. Therefore, in the dishwasher 50, it is necessary to provide the flange portion 16f so as to protrude outward from the side wall portion 16c in a portion where the lid body 14 abuts and closes via the seal member 23 (see FIG. 2).

That is, when the bottom component 17 is shared by the deep dishwasher 50, the fixed rail portion 12a of the slide mechanism 12 is attached to the side wall 10a of the housing 10 while ensuring the width dimension for the flange portion 16f. The structure for this is needed.

On the other hand, in the case of the shallow dishwasher 51, as shown in FIG. 5, the cleaning tank member 40 that is joined to the bottom component member 17 and constitutes the cleaning tank 29 has the left and right side walls 40a of the seal portion 54. It rises upward from the innermost circumference. Thereby, the width dimension for the flange part which protruded around the opening part of the uppermost part of the washing tank member 40 is securable. Therefore, the fixed rail portion 12 a of the slide mechanism 12 can be directly attached to the side wall 27 a of the housing 27. In addition, the structure of the sealing part 54 which consists of the groove part 17b, the sealing rib 40b, and the sealing member 18 is the same as that of the sealing part 21 of the deep dishwasher mentioned above.

The rail mounting member 13 reinforces the necessary portions of the left and right side walls 10a having a high height in the deep dishwasher 50 in a concentrated manner. Furthermore, when the rail mounting member 13 uses the shallow dishwasher 51 and the bottom component member 17 in common, the rail mounting member 13 secures a width dimension for the flange portion 16f, As a configuration for attaching to the 10 side walls 10a, a great effect is exhibited.

As described above, according to the present invention, it is possible to reinforce only a necessary part of a case of a dishwasher that is to be enlarged, and to obtain a case structure that can be easily processed while ensuring strength without cost. It becomes possible. Therefore, it is useful as a built-in type dishwasher or the like that pulls out a washing tank and puts in and out dishes.
