Description

  The present invention relates to a dishwasher.

  DESCRIPTION OF RELATED ART Conventionally, the dishwasher which can wash | clean tableware by spraying water (washing water) toward the tableware accommodated in the washing tank is known. The tableware is put in and out of the washing tank through a tableware inlet formed on the front surface of the dishwasher, for example. The tableware slot can be covered with, for example, two open / close doors (upper door and lower door) arranged side by side. Packing is attached to the peripheral edge of the tableware slot.When the upper and lower doors are closed, the upper and lower doors are pressed against the packing, and the tableware slot is closed watertight. ing.

Some dishwashers of this type have an upper door that opens and closes in conjunction with the opening and closing of the lower door (see, for example, Patent Document 1). When the lower door is opened, the upper door moves to the upper side of the washing tank so as to slide upward while moving away from the tableware inlet, and the inner surface (when facing the tableware inlet when closed) The front end portion is in a lower posture than the rear end portion with the surface) facing downward. According to such a configuration, the upper door can be satisfactorily opened even when the space above the dishwasher is narrow.
JP 2002-301003 A

  However, in the above prior art, water adhering to the inner surface of the upper door with the upper door opened falls to the top surface of the dishwasher, or the dish inlet is opened from an arbitrary position at the front end of the upper door. Or fall into the cleaning tank. When water adhering to the inner surface of the upper door falls on the top surface of the dishwasher, the top surface must be wiped down, which is troublesome. In addition, when water adhering to the inner surface of the upper door falls into the washing tank from any position at the front end of the upper door through the tableware inlet, not only looks bad, In some cases, water falling from the upper door may get on the hand, or water falling from the upper door may get wet on the dried tableware.

Some dishwashers have an exhaust port formed in the upper door for discharging steam in the washing tank to the outside. In such a configuration, when the upper door is opened, water (condensed water) adhering to the periphery of the exhaust port may fall on the top of the dishwasher.
On the other hand, it is possible to relatively easily prevent water in the washing tank from leaking out of the machine by providing a packing at the peripheral edge of the tableware inlet, but the steam in the washing tank is discharged from the tableware inlet to the outside of the machine. It is relatively difficult to prevent leakage of the steam, and when rattling occurs in the interlocking mechanism of the open / close door, steam easily leaks out of the machine from the tableware inlet. Therefore, there is a demand for a dishwasher capable of closing the dish slot more tightly.

The present invention has been made under such a background, it is to provide a dishwasher capable of closing the tableware inlet more watertight.

The invention according to claim 1 is a cleaning tank (4) for storing tableware, a tableware insertion port (5) formed on the front surface of the cleaning tank, for loading and unloading tableware to and from the cleaning tank, Two open / close doors (6, 7) for covering the tableware slot, each having an inner surface (6A, 7A) facing the tableware slot in a closed state, and one open / close door (7) The other opening / closing door (6) is formed on the inner surface (the end) of the other opening / closing door to open / close so that the other opening / closing door (6) slides with respect to the tableware insertion slot. The sliding contact surface includes a guide portion (37) and sliding contact surfaces (36A, 36B) that are formed at the peripheral edge of the tableware insertion port and contact the guide portion when the other opening / closing door is closed. The other opening / closing door is closed by guiding the guide portion to the rear side. It is an inclined surface for guiding the position (36B) dishwasher, characterized in that is provided with (1).

  According to this configuration, when one of the opening / closing doors is closed, the guide portion of the other opening / closing door is slidably contacted with the sliding contact surface, and the other opening / closing door is guided to the closed position side. The other door is guided to the closed position by being guided rearward along the inclined surface. Therefore, even when rattling occurs in the mechanism for interlocking the two doors, the inner surface of the door is more strongly pressed against the packing attached to the peripheral edge of the tableware slot. The inlet can be closed more watertight.

Embodiments of the present invention will be specifically described below with reference to the drawings.
FIG. 1 is a front view showing an external configuration of a dishwasher 1 according to an embodiment of the present invention. FIG. 2 is a left side view of the dishwasher 1. This dishwasher 1 not only can wash dishes by spraying water (washing water) toward the dishes stored in the dishwasher 1, but also introduces hot air into the dishes after washing. It also has the function of drying.

  With reference to FIG. 1 and FIG. 2, the dishwasher 1 is divided by the housing | casing 2 whose external shape is a substantially rectangular parallelepiped shape. The dishwasher 1 is of a wide type, and the casing 2 is formed so that the width is longer than the depth. An operation display panel 3 for setting the operation content of the dishwasher 1 and displaying the operation status is disposed in the lower front portion of the housing 2.

  A cleaning tank 4 for storing tableware to be cleaned is disposed in the housing 2 (see FIG. 2). On the front surface of the washing tank 4, a tableware inlet 5 for taking in and out the tableware is formed. The tableware slot 5 is inclined by a predetermined angle with respect to the vertical direction so as to recede as it goes upward. Thus, by setting it as the structure where the tableware insertion port 5 faces a little upwards, it can make it easy to take in and out the tableware with respect to the washing tank 4 from the upper front side of the dishwasher 1 via the tableware insertion port 5. .

  The tableware slot 5 can be opened and closed by two doors (upper door 6 and lower door 7). The upper door 6 can cover almost the upper half of the tableware slot 5, while the lower door 7 can cover almost the lower half of the tableware slot 5. A grip lever 8 is disposed at the center in the left-right direction of the upper end portion of the lower door 7 for the user to grip when the lower door 7 is opened and closed. Further, an exhaust port 9 that communicates the inside of the cleaning tank 4 with the outside of the machine with the upper door 6 and the lower door 7 closed is formed to extend in the left and right direction at the central portion in the left and right direction of the upper portion of the upper door 6. In addition, when the dishes are washed or dried, the steam in the washing tank 4 is discharged to the outside through the exhaust port 9.

FIG. 3 is a left side view of the dishwasher 1 and shows a state in which the upper door 6 and the lower door 7 are opened.
The upper door 6 and the lower door 7 are connected to each other by an interlocking mechanism (not shown) so that the upper door 6 opens and closes in conjunction with the opening and closing of the lower door 7. That is, as shown in FIG. 2, the grip lever 8 is gripped with the upper door 6 and the lower door 7 closed, and the lock for locking the lower door 7 in the closed position by pushing down the grip lever 8 downward. After unlocking the mechanism (not shown), the lower door 7 can be rotated forward and downward by pulling the grip lever 8, and the upper door 6 is moved along the tableware slot 5 in conjunction with this. Can be slid upward.

  As shown in FIG. 3, the lower door 7 has its inner surface 7 </ b> A (the surface facing the tableware inlet 5 in a closed state) in the most open state. On the other hand, as the lower door 7 opens, the upper door 6 rises while leaving the front along the tableware slot 5, and gradually tilts backward from the upper end thereof. When the upper door 6 is in the most open state, the front end (lower end) of the upper door 6 is inclined slightly lower than the rear end (upper end) with the inner surface 6A facing downward. . Thus, the space above the dishwasher 1 is narrow by adopting a configuration in which the upper door 6 slides with respect to the tableware inlet 5 and moves above the washing tank 4 (housing 2). Even in this case, the upper door 6 can be opened satisfactorily.

  A table basket (not shown) for holding tableware is arranged in the cleaning tank 4. In this embodiment, two tableware baskets (upper basket and lower basket) are arranged at regular intervals in the vertical direction. The left and right ends of the upper car are slidably attached to the inner surface of the cleaning tank 4 so that they can slide back and forth. On the other hand, a plurality of (for example, four) rollers are attached to the bottom of the lower cage, and the rollers are rolled on the bottom surface of the cleaning tank 4 and the inner surface 7A of the lower door 7 opened substantially horizontally. Thus, the lower car can be slid back and forth.

FIG. 4 is a plan view showing the configuration of the lower car 10.
Referring to FIG. 4, the right portion (range of about one third from the right end) of the lower basket 10 is a platter accommodating portion 10 </ b> A that can be accommodated in a state in which a relatively large dish such as a middle dish or a platter is set up. It has become. In addition, the portion from the center to the left side of the lower basket 10 (the range of about two-thirds from the left end) can accommodate bowls such as tea bowls, soup bowls, and bowls in a standing state. Part 10B. Between the platter accommodating part 10A and the bowl accommodating part 10B, a long chopstick accommodating part 10C is arranged in the front-rear direction. In addition to the chopsticks, a spoon, a fork or the like is set up in this chopstick accommodating part 10C. It can be accommodated in a state.

FIG. 5 is a view of the upper door 6 as viewed from the inner surface 6A side. FIG. 6 is a cross-sectional view of the upper door 6 taken along the vertical direction (short direction).
With reference to FIG. 5 and FIG. 6, the upper door 6 includes a main body 11 for opening and closing the tableware inlet 5 and a transparent cover 12 covering the front side of the main body 11 (the side opposite to the tableware inlet 5). I have. The main body 11 includes an inner surface plate 13 that constitutes an inner surface 6 </ b> A that faces the tableware slot 5 with the upper door 6 closed, and an outer surface plate 14 that constitutes the outer surface (front surface) of the main body 11. The inner surface plate 13 is made of, for example, PP (polypropylene), and the outer surface plate 14 is made of, for example, ABS (acrylonitrile butadiene styrene).

  The inner surface plate 13 includes, for example, an annular protrusion 15 formed so as to protrude forward, and an exhaust port 9 is formed by the inner surface of the annular protrusion 15. Openings 16 and 17 are formed in the outer plate 14 and the transparent cover 12 at positions corresponding to the annular protrusions 15 of the inner plate 13, respectively. The annular protrusion 15 is inserted into each opening 16, 17, and the tip of the annular protrusion 15 protrudes forward (slightly forward from the front surface of the transparent cover 12).

  The transparent cover 12 is made of, for example, transparent AS (acrylonitrile styrene). In this embodiment, the transparent cover 12 is attached to the outer surface plate 14 from the front with a sheet (not shown) sandwiched between the transparent cover 12 and the main body 11 (outer surface plate 14). The sheet is a flexible member formed to a thickness of about 0.2 mm by, for example, PET (polyethylene terephthalate), and is curved along the surface (front surface) of the outer surface plate 14. Covering the entire surface of the. The sheet is transparent, and the surface on the outer plate 14 side is color-printed with a predetermined color, for example.

  Water sealing ribs 18 projecting from the upper end to the lower end of the upper door 6 in the vertical direction are provided on the left and right ends of the inner surface 6 </ b> A of the upper door 6. The water sealing rib 18 is for preventing water in the cleaning tank 4 from leaking out of the machine from the tableware inlet 5. In this embodiment, not only the water sealing rib 18 but also the upper end of the upper door 6 at a position closer to the center than the position where the water sealing rib 18 is formed at the left and right ends of the inner surface of the upper door 6. A labyrinth rib 19 extending in the up-down direction from the bottom end to the bottom end is provided. By providing the labyrinth rib 19, water flowing from the cleaning tank 4 toward the water seal rib 18 can be temporarily blocked by the labyrinth rib 19, so that it is more effective for water to leak out of the machine from the tableware inlet 5. Can be prevented.

  A substantially rectangular housing recess 20 is formed around the exhaust port 9 on the inner surface 6A of the upper door 6, and an exhaust port cover 21 for covering the rear side of the exhaust port 9 is fitted into the housing recess 20. ing. On the inner surface 6A of the upper door 6 on both the left and right sides of the exhaust port cover 21, first ridges 221 that are inclined so as to approach the lower end portion toward the left and right ends of the upper door 6 are formed. Yes. The inner surface 6 </ b> A of the upper door 6 below the exhaust port cover 21 has a vertex at the center in the left-right direction of the upper door 6, and approaches the lower end as it goes from the vertex to the left and right ends of the upper door 6. In this way, three substantially rectangular (substantially mountain-shaped) ridges (second ridge 222, third ridge 223, and fourth ridge 224) are formed so as to be lined up and down. The first to fourth protrusions 221 to 224 are connected to the labyrinth rib 19 on the left and right ends of the upper door 6, respectively.

  Since the upper door 6 moves to the upper side of the cleaning tank 4 in an open state and its front end (lower end) is lower than the rear end (upper end), the upper door 6 The water adhering to the inner surface 6A of the door 6 tends to flow to the front end side along the inner surface 6A. Water that is about to flow to the front end side along the inner surface 6A of the upper door 6 is guided to the left and right end portions of the upper door 6 by the first to fourth protrusions 221 to 224, and the front end (lower end) of each labyrinth rib 19 ) It can be dropped into the cleaning tank 4 through the tableware inlet 5 from 19A.

  Therefore, water adhering to the inner surface 6A of the upper door 6 falls to the top surface of the dishwasher 1 (housing 2) or is washed from any position at the front end of the upper door 6 through the tableware inlet 5. It can prevent falling into the tank 4, and the water adhering to the upper door 6 can be dropped to a more suitable position. In addition, if the height of the first to fourth protrusions 221 to 224 is increased or the number of protrusions is increased, more water can be guided to the left and right ends of the upper door 6. However, the configuration is not limited to the configuration in which the water adhering to the inner surface 6A of the upper door 6 is guided to the left and right ends of the upper door 6, but may be configured to be guided to one of the left and right ends.

  In this embodiment, with the upper door 6 opened, the front end 19A of each labyrinth rib 19 is positioned above the outside of the lower car 10, and the water dropped into the cleaning tank 4 from the front end 19A of each labyrinth rib 19 As shown by a two-dot chain line in FIG. 4, it falls to the vicinity of the right front end portion and the left front end portion of the lower car 10 (near the front roller 10D). As described above, the water that has fallen from the front end 19A of each labyrinth rib 19 falls to the vicinity of the peripheral edge of the lower basket 10 in the cleaning tank 4, so that the dropped water is held in the lower basket 10. It is possible to prevent the tableware from falling. Therefore, the water adhering to the upper door 6 can be dropped to a more suitable position. However, the position where the water falls from the front end 19A of each labyrinth rib 19 is another position in the vicinity of the peripheral edge of the lower car 10 (the part within the range of the lower car 10 or outside the lower car 10, etc., where there is no tableware) ).

FIG. 7 is a view showing a configuration of the exhaust port cover 21. 7A is a view of the exhaust port cover 21 as viewed from the inside (exhaust port 9 side), and FIG. 7B is a cross-sectional view taken along the arrow AA in FIG. 7A. .
With reference to FIGS. 6 and 7, the exhaust port cover 21 includes a substantially rectangular facing plate 23 that faces the exhaust port 9 in a state where the exhaust port cover 21 is fitted in the housing recess 20 formed on the inner surface 6 </ b> A of the upper door 6. An upper plate 24, a lower plate 25, a left plate 26 and a right plate 27 rising from the four sides of the opposing plate 23 to the upper door 6 side (exhaust port 9 side) are included. A labyrinth rib 28 protrudes on the inner surface (surface on the exhaust port 9 side) of the counter plate 23 so as to surround the left and right sides and the lower side of the exhaust port 9, and the exhaust port 9 is formed by the labyrinth rib 28 and the upper plate 24. By surrounding the rear side, water in the cleaning tank 4 can be prevented from leaking out of the apparatus through the exhaust port 9.

  The left and right plates 26 and 27 are each formed with a substantially rectangular notch 29 from the tip to the opposing plate 23 side to a predetermined depth (a depth that does not reach the opposing plate 23). A recess 30 is formed in the inner surface 6A of the upper door 6 at a portion facing each notch 29 of the left and right side plates 26 and 27 of the exhaust port cover 21 (see FIG. 5). With such a configuration, steam generated in the cleaning tank 4 when cleaning or drying the tableware enters the exhaust port cover 21 through the recess 30 and the notch 29 and is discharged from the exhaust port 9 to the outside of the machine. .

  In this embodiment, since the notches 29 formed in the left and right side plates 26 and 27 of the exhaust port cover 21 are deep enough not to reach the counter plate 23, the counter plate 23 and the side plates 24 to 27 are cut. A space surrounded by the portion on the counter plate 23 side with respect to the line along the lower edge of the notch 29 constitutes the water reservoir 31. That is, when the upper door 6 is opened, the facing plate 23 is positioned substantially horizontally on the lower side, and water adhering to the periphery of the exhaust port 9 (condensed water) opens the upper door 6. When the water drops, the water is received by the exhaust port cover 21 and collected in the water reservoir 31. Then, the water accumulated in the water reservoir 31 can be dropped into the cleaning tank 4 when the upper door 6 is closed thereafter. Therefore, when the upper door 6 is opened, it is possible to prevent water adhering to the periphery of the exhaust port 9 from falling on the top surface of the dishwasher 1 (housing 2). It can be dropped to a suitable position.

However, the water reservoir 31 is not constituted by the side plates 24 to 27 of the exhaust port cover 21, but, for example, ribs protruding from the inner surface of the exhaust port cover 21 to the upper door 6 side (exhaust port 9 side) are separately provided. It may be provided and the water reservoir may be constituted by this rib.
FIG. 8 is a front view of the cleaning tank 4.
Referring to FIG. 8, the upper door 6 and the lower door 7 are closed at the peripheral edge portions (upper edge portion 32, left edge portion 33 and right edge portion 34) of the tableware inlet 5 of the cleaning tank 4. A packing 35 is attached to the inner surfaces 6A and 7A of the doors 6 and 7 so as to prevent the water in the cleaning tank 4 from leaking out of the machine from the tableware inlet 5. Outside the packing 35 of the left and right edge portions 33, 34 of the tableware slot 5, guide ribs extending in the vertical direction at positions where the lower end portions of the left and right ends of the upper door 6 face each other when the upper door 6 is closed. 36 is protrudingly provided. The front surface of the guide rib 36 includes a parallel surface 36A that extends substantially in parallel along the left and right edge portions 33, 34 of the tableware inlet 5, and an inclined surface 36B that retreats downward from the lower end of the parallel surface 36A. On the other hand, sliding contact projections 37 are formed on the lower left and right ends of the inner surface 6 </ b> A of the upper door 6 so as to protrude from the water sealing rib 18 in the left-right direction for sliding contact with the guide rib 36 when the upper door 6 is closed. (See FIG. 5).

  Engaging protrusions 38 that protrude upward are formed on the left and right ends of the upper edge portion 32 (outside the packing 35) of the tableware insertion slot 5. On the other hand, engaging recesses 39 are formed on both the left and right sides of the upper surface 6A of the upper door 6 (see FIG. 5), and slides downward along the tableware slot 5 when the upper door 6 is closed. The engagement protrusion 38 can be engaged with the engagement recess 39 of the door 6.

FIGS. 9-12 is a longitudinal cross-sectional view of the dishwasher 1 for demonstrating the aspect at the time of closing the upper door 6 and the lower door 7. FIG.
As shown in FIG. 9, when the lower door 7 is closed, the upper door 6 is also closed in conjunction with the lower door 7, and the upper door 6 approaches the tableware slot 5 before the lower door 7. Thereafter, when the lower door 7 is further closed, the tip of the sliding protrusion 37 of the interlocking upper door 6 comes into contact with the inclined surface 36B of the guide rib 36 (see FIG. 10), and further interlocked when the lower door 7 is closed. The tip of the sliding protrusion 37 of the upper door 6 slides downward along the inclined surface 36B of the guide rib 36, and the upper end of the lower door 7 contacts the lower end of the upper door 6 (see FIG. 11).

  When the lower door 7 is further closed from this state, the lower end portion of the upper door 6 is pressed by the upper end portion of the lower door 7 as shown in FIG. The upper door 6 is pulled downward until it reaches the lower end of the surface 36B, and the upper door 6 reaches the closed position. At this time, the engagement protrusion 38 enters the engagement recess 39 of the upper door 6 so that the upper door 6 does not slide any more, and the upper door 6 does not move in the direction away from the tableware inlet 5 (forward). To be regulated.

  As described above, the upper door 6 and the lower door are configured such that the tip of the sliding protrusion 37 is guided rearward along the inclined surface 36B of the guide rib 36 and the upper door 6 is pulled into the closed position. The packing 35 in which the inner surface 6A of the upper door 6 is attached to the peripheral edge of the tableware insertion slot 5 (especially, the sliding direction when closing the upper door 6) Since it is more strongly pressed against the packing 35) attached to the upper edge 32 of the tableware inlet 5 on the upstream side, the tableware inlet 5 can be closed more tightly.

  Further, by adopting a configuration in which the tip of the sliding contact projection 37 is slidably contacted from the parallel surface 36A of the guide rib 36 to the inclined surface 36B and pulled from the front side to the rear side, the tip of the sliding contact projection 37 is parallel surface 36A. It is possible to prevent the inner surface 6 </ b> A of the upper door 6 from coming into contact with the packing 35 attached to the peripheral edge of the tableware inlet 5. Therefore, until the upper door 6 reaches the vicinity of the closed position, the inner surface 6A of the upper door 6 can be prevented from slidingly contacting the packing 35, so that the packing 35 can be prevented from sliding and deteriorating.

  Further, when the upper door 6 is closed, the upper door 6 is restricted to the closed position by the engagement of the engagement protrusion 38 and the engagement recess 39 so that the upper door 6 does not move away from the tableware inlet 5. By doing so, the upper door 6 can be reliably maintained in the closed position. Therefore, it is possible to prevent the upper door 6 from being deformed or an external force being applied to the upper door 6 to reduce the watertightness of the upper door 6 with respect to the tableware insertion port 5, so the tableware insertion port 5 is closed more tightly. be able to.

  In particular, when the upper door 6 is configured to slide along the tableware slot 5, the lower end of the upper door 6 is pressed backward by the upper end of the lower door 7 in a state where the upper door 6 is closed. However, the upper end of the upper door 6 (the end opposite to the lower door 7) is likely to move away from the tableware slot 5 (front), and the water tightness at the upper end of the upper door 6 is likely to deteriorate. . Therefore, the watertightness can be more effectively improved by setting the engagement position between the engagement protrusion 38 and the engagement recess 39 as the upper end of the upper door 6 as in this embodiment.

  In the above description, the sliding protrusion 37 does not contact the parallel surface 36A of the guide rib 36. However, when the upper door 6 is deformed or the backlash occurs in the interlocking mechanism, the upper door When the slidable contact projection 37 is brought into contact with the parallel surface 36A of the guide rib 36 when the slidable contact 6 is closed, the slidable contact projection 37 is slidably contacted from the parallel surface 36A to the inclined surface 36B. It can be pulled down well.

FIG. 13 is a view of a vertical section of the upper part of the dishwasher 1 as seen from the right side. Moreover, FIG. 14 is the figure which looked at the cross section of the left front end part of the dishwasher 1 from upper direction.
A car holding member 40 for holding the upper car is attached to the upper part of the inner surface of the left and right side plates 4A of the cleaning tank 4. Since the left and right car holding members 40 have the same configuration, only the configuration of the left car holding member 40 will be described with reference to FIGS. 13 and 14.

  The car holding member 40 covers the entire upper part of the inner surface of the left side plate 4A, and two rails 41 for engaging with the left edge of the upper car and slidably holding it in the front-rear direction are fixed in the vertical direction. Are arranged in parallel with an interval of. According to such a configuration, the height of the upper car can be switched between two levels depending on which of the two rails 41 arranged vertically is engaged with the upper car.

  As shown in FIG. 6, a recess 42 is formed at the upper end of the labyrinth rib 19 of the upper door 6. With such a configuration, even when the upper door 6 is slid along the tableware inlet 5 to open and close, the labyrinth rib 19 of the upper door 6 slides on the packing 35 attached to the upper edge 32 of the tableware inlet 5. Since the contact can be prevented, the packing 35 can be prevented from being slid and deteriorated. Thus, when the hollow 42 is formed in the upper end part of the labyrinth rib 19, the water in the washing tank 4 will be directly applied to the water seal rib 18, and there is a possibility that the water tightness in this part is lowered. Therefore, a labyrinth rib 43 having a shape corresponding to the recess 42 of the labyrinth rib 19 of the upper door 6 is formed on the front upper end portion of the car holding member 40. Since the labyrinth rib 43 can prevent the water in the cleaning tank 4 from being directly applied to the water seal rib 18, the tableware inlet 5 can be closed more tightly.

  At the upper end portion of the labyrinth rib 43, a flange portion 44 that protrudes in the horizontal direction is provided so as to extend in the front-rear direction and bend in a substantially square shape so that the front end portion is inclined obliquely downward. The flange 44 can prevent water in the cleaning tank 4 from entering the water sealing rib 18 through the gap above the labyrinth rib 43. Therefore, it is possible to more effectively prevent the water in the cleaning tank 4 from being directly applied to the water seal rib 18, so that the tableware inlet 5 can be closed more tightly.

The present invention is not limited to the contents of the above embodiments, and various modifications can be made within the scope of the claims .
