The dish washer includes: a main body including a dish washing compartment having a dish inlet/outlet; and a door for opening and closing the tableware inlet/outlet, and including an outer panel and an inner panel with a gap therebetween, wherein the door includes a panel movement preventing member disposed in the gap between the outer panel and the inner panel and preventing a relative movement of the outer panel and the inner panel. The dishwasher of the present invention has a panel movement preventing member interposed between an inner panel and an outer panel of a door, and thus prevents relative movement of the inner panel and the outer panel, and prevents deformation into a diamond shape, thereby reinforcing a stable structure of the door, and preventing leakage due to deformation.

Description

Dish-washing machine

Technical Field

The present disclosure relates to a dishwasher, and more particularly, to a door of a dishwasher having a panel movement preventing structure for preventing deformation.

Background

The door of the dishwasher has a box-like shape, with an inner panel and an outer panel coupled by side panels, leaving a space between the inner panel and the outer panel to accommodate various components therein, such as a control circuit board, wiring, etc. In this case, the door is blocked in forward, backward, leftward, rightward and upward directions except for the downward direction, and is hollow inside. In particular, the dishwasher mainly employs a lower hinge structure to open and close a door to be tilted up and down, and thus a load is concentrated on the lower portion when the door is opened and closed.

Because the inner and outer panels move relative to each other as the load of the door is concentrated in the lower portion when the door is opened to tilt up and down, such a door (whose interior is hollow, particularly shaped like a box opened downward) is deformed from a rectangular shape to a diamond shape, i.e., deformed.

In particular, the inner and outer panels of the door need to be separated from each other to replace and repair the interior components. Thus, the inner and outer panels are detachably coupled to each other. Such detachable coupling between the inner and outer panels causes deformation of the door due to relative movement between the inner and outer panels.

In addition, the door in the large-sized dishwasher has a large area and thus is more easily deformed by the relative movement between the inner and outer panels.

The deformation of the door of the dishwasher not only prevents smooth opening and closing of the door, but also causes water leakage during the operation of the dishwasher, thereby making the durability unsatisfactory for consumers.

Detailed Description

Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so as to be easily implemented by one of ordinary skill in the art. The present disclosure may be embodied in a variety of different forms and is not limited to the embodiments described herein. For clarity of description, like reference numerals refer to like elements throughout.

Hereinafter, the main operation of the dishwasher according to the present disclosure and features of elements included in the dishwasher will be described in detail.

As shown in fig. 1, a dishwasher 1 according to the present disclosure includes a main body 100 having a washing chamber 110 formed therein with a washing inlet opening forward, and a door 130 mounted to a front portion of the main body 100 and tiltable up and down to open and close the washing inlet of the washing chamber 110.

In the washing chamber 110, cutlery baskets 112a and 112b for accommodating cutlery and the like are provided up and down. Further, in order to spray the washing water toward the dishes received in the dish baskets 112a and 112b, the fixed nozzle 113a is disposed in an inner upper portion of the washing chamber 110, and the rotating nozzles 113b and 113c are respectively disposed in middle and lower portions of the washing chamber 110. In addition, a water supply pipe 115 having a water supply control valve 114 is provided at the back of the washing chamber 110 so that washing water can be supplied to the inside of the washing chamber 110 at an initial stage.

Below the washing chamber 110, a washing pump 116 is provided to supply washing water to the nozzles 113a, 113b, and 113c in the washing chamber 110 and to the nozzles 113a, 113b, and 113c in the washing chamber 110. Further, a sump 117 recessed by a predetermined depth to collect wash water and contaminated water is formed at a lower portion of the washing chamber 110, and the sump 117 is provided with a filter 118 to filter out purified contaminated water. A water inlet pipe 119 is connected between the washing pump 116 and the sump 117 to circulate the washing water filtered through the filter 118, a drain pump 120 is provided under the sump 117 to drain the washing water after the washing operation is completed, and a drain pipe 121 extends from the drain pump 120 to the outside of the main body 100.

As shown in fig. 4, the door 130 is coupled to opposite front lower sides of the main body 100 by a pair of hinge units 122. A pair of hinge units 122 are provided at lower opposite sides of the door 130, respectively. As shown in fig. 3, the hinge unit 122 includes a portion 124a supported on a first sidewall 135a of the inner panel 132 of the door 130, a portion 124b supported on a first coupling protrusion 135b of the door 130, a portion 124c supported on the support bracket 140, and an inclined bar 124d bent and extended rearward from the portion 124c supported on the support bracket 140.

Further, a buffer spring 125 is provided in a lower inner portion of the main body 100, and allows the door 130 to be easily opened and closed. The buffer spring 125 connects a spring holder 126 provided in a lower inner portion of the main body 100 and an end of the inclined lever 124d of the hinge unit 122. When the user opens the door 130, the buffer spring 125 prevents the door 130 from being suddenly opened, and allows the door 130 to be easily closed with a small force.

Further, as shown in fig. 3, the door 130 is formed of an outer panel 131 and an inner panel 132 detachably coupled to each other. Although not shown in detail in the drawings, the front portion of the door 130 (i.e., the front portion of the exterior panel) is provided with a control portion including a plurality of control buttons for controlling the operation of the apparatus, a display for displaying an operation state, and the like. Further, wiring for electrical connection with a control circuit board associated with a control portion of the front of the door 130 is provided inside the door 130.

The outer panel 131 and the inner panel 132 are respectively provided and assembled into the door 130. The assembled door 130 includes a first lateral side 135 of the inner panel 132 and a second lateral side 136 of the outer panel 131. As shown in fig. 3, the first lateral side 135 of the inner panel 132 includes a first sidewall 135a bent and extended rearward from left, right and upper edges of the inner panel 132, and a first coupling protrusion 135b bent and extended laterally from the first sidewall 135 a. The second lateral side 136 includes a second sidewall 136a bent and extended forward from left, right and upper edges of the outer panel 131, and a second coupling protrusion 136b bent and extended laterally again from the second sidewall 136a. The outer panel 131 and the inner panel 132 are coupled in a state where the first coupling protrusion 135b and the second coupling protrusion 136b overlap. The first and second coupling protrusions 135b and 136b overlapped with each other include a plurality of screw holes 138a and 138b in respective portions fastened by screws and nuts. Of course, the door 130 may include an outer panel 131 and an inner panel 132 formed as a single body.

The inner panel 132 of the door 130 includes a recessed portion 137 at a lower portion thereof and recessed toward the outer panel 131. The concave portion 137 not only enhances the structural strength of the door 130, but also serves as a space expanding from the inside of the washing chamber 110. The space between the bottom of the concave portion 137 and the outer panel 131 is narrow, but the space between the edge 139 surrounding the concave portion 137 and the outer panel 131 is wide.

According to an embodiment of the present disclosure, the panel movement preventing member 200 is placed in the lower portion of the door 130. Further, the panel movement preventing member 200 is placed to include the middle portion of the door 130. The panel movement preventing member 200 is interposed between the inner panel 132 and the outer panel 131 of the door 130. In particular, the panel movement prevention member 200 is disposed at an intermediate position of the edge 139 below the recessed portion 137 of the inner panel 132. The panel movement preventing member 200 firmly holds and supports the inner sides of the inner panel 132 and the outer panel 131 and prevents relative movement between the inner panel 132 and the outer panel 131. When the panel movement preventing member 200 extends as long as possible in the lateral direction from the lower middle portion of the door 130, the effect of preventing the deformation of the door becomes better. However, wiring extending upward from the lower portion needs to be placed in the door 130, and thus the panel movement preventing member 200 may have a length corresponding to one third of the lateral width of the door 130. Alternatively, the panel movement preventing member 200 may be formed as long as possible, and the panel movement preventing member 200 includes a wiring through hole (not shown).

When the door 130 is deformed, the highest portion of the door 130 where the control portion is located is most affected by the deformation. Accordingly, when a force is applied to deform the product, the door 130 is easily deformed from a substantially rectangular shape to a diamond shape. To solve this problem, as in the embodiment of the present disclosure, it is effective to keep the middle portions of the inner panel 132 and the outer panel 131 assembled in the door 130, not the opposite end portions (i.e., hinge portions) of the door 130.

The panel movement preventing member 200 may be provided as at least one panel holding block having a surface that contacts the inner surfaces of the outer panel 131 and the inner panel 132 and holds the inner surfaces of the outer panel 131 and the inner panel 132. Here, the at least one panel holding block may be provided as a single body or an assembled body.

Fig. 5 is a sectional view showing a mounted state of the panel movement preventing member 200, fig. 6 is a perspective view of the panel movement preventing member 200 according to the first embodiment of the present disclosure, and fig. 7 is a partial sectional view showing a mounted state of the panel movement preventing member 200.

The panel movement preventing member 200 includes an inner retaining block 210 and an outer retaining block 220, which are provided and assembled by a concave structure and a convex structure, respectively. The contact surfaces between the inner side holding block 210 and the inner panel 132 and between the outer side holding block 220 and the outer panel 131 may be appropriately set as needed.

The panel movement preventing member 200 may include an inner retaining block 210 and an outer retaining block 220 as shown in fig. 6. The inner and outer retaining blocks 210, 220 may be manufactured by plastic injection molding, but may alternatively be manufactured by metal plates alone or a combination of metal plates and plastic.

The inside retaining block 210 includes an inner panel support 212 supported on the inner panel 132, at least one recessed portion 214 formed on opposite sides of the inner panel support 212, a tub escape 216 concavely and laterally formed in a lower portion of the door, and a wire holder 218 protruding on opposite sides.

The inner panel support 212 is attached to the lower intermediate inner surface (i.e., the raised boss portion) of the inner panel 132 by screws or an adhesive (or glue).

The at least one concave portion 214 accommodates a convex portion 224 of the outer holding block 220 and is coupled with the convex portion 224 (to be described later). The inner panel 132 and the outer panel 131 need to be disassembled based on the coupling between the inner and outer retaining blocks 210 and 220 of the concave and convex structures to replace or repair the components.

The wiring holder 218 is configured to arrange and hold wiring extending upward from a lower portion within the door 130. The wiring holder 218 includes a first holding projection 217-1, a second holding projection 217-2, and a third holding projection 217-3 projecting from opposite sides. The first and third holding projections 217-1 and 217-3 are spaced apart from each other in the lateral direction, and the second holding projection 217-2 is spaced apart from an intermediate portion between the first and third holding projections 217-1 and 217-3 in a direction perpendicular to the lateral direction. The first, second and third holding protrusions 217-1, 217-2 and 217-3 include a wiring accommodation groove 219 on surfaces facing each other to accommodate the wiring. The wiring is inserted and held in the wiring accommodation groove 219 located in the space between the first holding projection 217-1, the second holding projection 217-2, and the third holding projection 217-3. The wiring holder 218 is not limited to the above-described three holding protrusions, but may include two or more than four protrusions. Alternatively, the wire holder 218 may be based on wires that directly compress wires or bond wires with springs and similar elastomers, instead of fitting wires between the first, second, and third holding protrusions 217-1, 217-2, 217-3.

The tub escape portion 216 refers to a groove that prevents interference with the tub 128 protruding from the bottom of the washing compartment 110 when the door 130 is tiltably opened and closed. The tub 128 of the lower portion of the washing chamber 110 refers to a protrusion that prevents washing water used in the washing process from leaking to the outside. The tub escape 216 is elongated longitudinally in the lower part of the inner holding block 210.

The outer holding block 220 includes an outer panel support 222 contacting the outer panel 131 and supported on the outer panel 131, and at least one projection 224 projecting from a side opposite to the outer panel support 222. The outer panel support 222 is attached to the lower intermediate inner surface of the outer panel 131 by screws or an adhesive (or glue). The at least one male portion 224 is inserted into the at least one female portion 214 of the medial retention block 210.

As described above, the panel movement preventing member 200 connects and maintains the inner surface of the inner panel 132 and the inner surface of the outer panel 131 to effectively reinforce the strength of the door 130, thereby maximizing convenience in using the dishwasher, such as stable closing, prevention of leakage due to deformation, and the like.

According to another embodiment, the panel movement preventing member 200 may be formed as a single body of the panel holding block and have opposite surfaces facing the inner surface of the inner panel 132 and the inner surface of the outer panel 131, both of which are attached by an adhesive. However, when the product is repaired or inevitably disassembled, the continuous function of the panel movement preventing member 200 is not desirable. Accordingly, the panel movement preventing member 200 may have a fastening structure such as a magnet, a hook, or the like that is easily detachable from one of the inner panel 132 and the outer panel 131.

Fig. 8 is a sectional view showing the installation of the panel movement preventing member 300 according to the second embodiment of the present disclosure to a door. The panel movement preventing member 300 includes a middle holding block 310 placed in a lower middle portion of the door 130, and a pair of outer holding blocks 320 and 330 placed at lower opposite sides of the door 130, respectively. The middle holding block 310 and the pair of outer holding blocks 320 and 330 may be manufactured by plastic injection molding, but may also be manufactured by only a metal plate or a combination of a metal plate and plastic.

The middle holding block 310 and the pair of outer holding blocks 320 and 330 include inner panel supports 312, 322 and 332 in contact with the inner surface of the inner panel 132, outer panel supports 314, 324 and 334 in contact with the inner surface of the outer panel 131, and tub avoidance (not shown) formed on the bottom surface.

The pair of outer retention blocks 320 and 330 includes sloped lateral surfaces 326 and 336 facing the corner between the outer panel 131 and the second sidewall 136a. The inclined lateral surfaces 326 and 336 may include lateral surface contact portions (not shown) that extend to be inclined toward the second sidewall 136a and contact an inner surface of the second sidewall 136a.

The outer panel supports 314, 324, and 334 are attached to the inner surface of the outer panel 131 by an adhesive (or glue). The inner panel supports 312, 322, and 332 include permanent magnets 313, 323, and 333 that are detachably attached to the inner surface of the inner panel 132. In this case, the inner surface of the inner panel 132 to which the inner panel supports 312, 322, and 332 are attached includes the metal plates 311, 321, and 331 or magnets having opposite polarities. Instead of the permanent magnets 313, 323, and 333, one side between the inner panel supports 312, 322, and 332 and the inner panel 132 may be provided with hooks, and the other side may be provided with hook holders.

Each end portion of the angled supports 414 and 424 has a gradually expanding and widening width. The inclined supports 414 and 424 having such wide end portions can effectively support the door 130 in a wide range of up-down directions. The inner panel supports 412 and 422 are secured to the inner surface of the inner panel 132 by an adhesive (or glue). Alternatively, the inclined supports 414 and 424 may be maintained only in contact or may be detachably fastened. The pair of tilt support holders 410 and 420 may comprise a single tilt support holder in which the inner panel supports 412 and 422 are integrally connected to each other rather than separate bodies supporting two spaced apart positions of the inner panel 132. The pair of inclined support holders 410 and 420 may include at least one curved support (not shown) curved from end portions of the inclined supports 414 and 424 and in surface contact with the outer panel 131 and/or the second sidewall 136a.

The pair of inclined support holders 610 and 620 may include at least one curved support (not shown) curved from the inclined supports 614 and 624 and in surface contact with the outer panel 131 and/or the second sidewall 136a. The bracket supports 612 and 622 may be fastened to the support bracket 140 by an adhesive (or glue) or screws. The inclined supports 614 and 624 may be in contact with or detachably fixed to the outer panel 131 or the second side wall 136a and/or in contact with or detachably fixed to corners between the outer panel 131 and the second side wall 136a. The pair of inclined support holders 610 and 620 may be implemented by a single body in which the bracket supports 612 and 622 for supporting two separate positions of the support bracket 140 are integrally connected.

As shown in fig. 12, the stent support 612 includes two separate supports 615 and 617, and the two separate supports 615 and 617 can be folded over each other to reduce their lengths. The rack support 612 comprises a folding hinge unit 613 by means of which folding hinge unit 613 two separate supports 615 and 617 are foldable. The two separate supports 615 and 617 include a concave portion 619 and a convex portion 618, which concave portion 619 and convex portion 618 may be coupled to each other when folded with respect to the folding hinge unit 613.

Fig. 13 is a perspective view showing that the tilt bearing holder 610 is folded in the panel movement preventing member 600 according to the fifth embodiment of the present disclosure. The dishwasher 1 may have a door 130, the width of the door 130 being narrowed according to model. Thus, when two separate supports 615 and 617 are folded up to reduce the length, the space between the two positions supported by the inclined supports 614 and 624 of the pair of inclined support holders 610 and 620 is reduced. Similarly, the change in length of the inclined support holders 610 and 620 allows the panel movement preventing member 600 to be commonly applied to doors of products having different sizes, thereby reducing production costs.

Fig. 14 is a perspective view of a different tilt bearing retainer 610. As shown in the drawings, the tilting support holder 610 includes a bracket support 612 supported at one position of the support bracket 140; a tilting support 614 integrally extended from the bracket support 612 and extending obliquely outward from one position toward a corner between the outer panel 131 and the second sidewall 136 a; and at least one curved support 616, 618 curved from the inclined support 614 and in surface contact with the outer panel 131 and the second side wall 136a. The bracket support 612 is fastened to the support bracket 140 by an adhesive (or glue) or a screw. The end portion of the inclined support 614 is in contact with the corner between the outer panel 131 and the second side wall 136a. At least one curved support member 616, 618 is in contact with the outer panel 131 and/or the second side wall 136a. Here, the end portions of the inclined support 614 and/or the curved supports 616, 618 may be in contact with the corner between the outer panel 131 and the second side wall 136a, or detachably fixed to the corner between the outer panel 131 and the second side wall 136a, the outer panel 131 and the second side wall 136a. As described above, the inclined support holder 610 may support all of the corners between the outer panel 131 and the second sidewall 136a, the outer panel 131, and the second sidewall 136a.

Fig. 15 is a sectional view schematically illustrating the installation of a panel movement preventing member 700 according to a sixth embodiment of the present disclosure to a door 130. The panel movement preventing member 700 includes a support bracket 140 for holding and supporting a pair of hinge units 122 respectively placed at opposite sides of a lower portion of the door 130, a pair of inclined support holders 710 and 720 placed at opposite end portions of the support bracket 140, and an inner panel support 730 placed in the middle of the support bracket 140. When the support bracket 140 for holding and supporting the pair of hinge units 122 is not present in the panel movement preventing member 700, an additional support bracket for supporting the panel movement preventing member 700 may be provided. The pair of inclined support holders 710 and 720 may be manufactured by plastic injection molding, but may alternatively be manufactured only by a metal plate or a combination of a metal plate and plastic. The inner panel support 730 may be made of sheet metal, but may alternatively be made of plastic alone or a combination of sheet metal and plastic. The support bracket 140 may be made of sheet metal, but may alternatively be made of plastic alone, or a combination of sheet metal and plastic.

The pair of inclined support holders 710 and 720 have the same structure as the inclined support holder 610 of fig. 11, and thus duplicate description will be omitted.

The inner panel support 730 is formed by, for example, bending and machining opposite ends of a metal plate to have a "≡" shaped cross section, and has one curved side fastened to the middle of the support bracket 140 and the other curved side fastened to the inner panel 132 with screws or an adhesive (glue).

Although some embodiments of the present disclosure have been described in detail, various changes may be made to the disclosure without departing from the scope of the claims.
