Description

  The present invention relates to a dishwasher that sprays cleaning water onto dishes set in a basket for cleaning.

  A conventional general dishwasher will be described with reference to FIGS.

4 and 5, a conventional dishwasher has a washing tank 1 having an opening 1 a on the front surface and a door 2 that opens and closes the opening 1 a, and a nozzle 3 that jets washing water to the center of the bottom of the washing tank 1. In the washing tank 1, an upper basket 4 and a lower basket 5 are provided as baskets for storing tableware 10. When the door 2 is opened, the lower basket 5 is movable between the door 2 and the cleaning tank 1 in the front-rear direction. The upper basket 4 is supported by a rail portion 6 provided on the wall surface in the cleaning tank 1 so as to be movable in the front-rear direction.

  An accessory case 7 is fixed near the center of the lower basket 5, and a heater 8 is used at the bottom of the cleaning tank 1 to warm the cleaning water. A cleaning pump 9 is provided. The tableware 10 is set in the upper basket 4 and the lower basket 5, the small items 11 such as spoons and forks are set in the accessory case 7, and a drain port 12 is provided in the lower part of the cleaning tank 1. Is provided.

  In addition, as shown in FIG. 6, there is also a dishwasher in which a plurality of rail portions 6 for moving the upper basket 4 in the front-rear direction are provided in the washing tank 1 in the vertical direction. In this figure, the example of the dishwasher which provided the rail part 6 in three places up and down is shown (for example, refer patent document 1).

  Next, the operation of the conventional dishwasher will be described.

  First, the door 2 is opened, the lower basket 5 is pulled out on the door 2 and the small items 11 are set in the tableware 10 and the small case 7, and the upper table 4 is pulled forward and the tableware 10 is set. I do.

  Moreover, as shown in FIG. 6, in the dishwasher which provided the rail part 6 at three places up and down, before the tableware 10 is set, the rail part 6 is selected according to the size of the tableware 10, and the upper basket 4 Move up and down. That is, the height can be adjusted in three stages depending on the size of the tableware 10. For example, when the tableware 10 to be set in the lower basket 5 is large, the upper basket 4 may be supported by the upper rail portion 6.

Then, the cleaning water in the cleaning tank 1 is heated by the heater 8, sucked from the drain port 12 in the cleaning tank 1 by the cleaning pump 9, pumped to the nozzle 3, and vigorously moved to the tableware 10 from the nozzle 3.

In this way, the dishes 10 set in the upper basket 4 and the lower basket 5 and the accessories 11 set in the accessory case 7 are washed.
JP 2004-321283 A

  However, in the configuration of the conventional dishwasher, the size of the tableware 10 that can be set in both the upper basket 4 and the lower basket 5 is determined. Therefore, when setting tableware 10 such as dishes and bowls with a large diameter, and cups with a long total length, tableware larger than the set space cannot be set.

  If the washing tank 1 is enlarged as a means of ensuring a wide set space for the dishes 10, the dishwasher body becomes large, and the dishwasher cannot be installed in a kitchen sink. Since it corresponds to a set, the means to enlarge the washing tank 1 generally is not good.

  In addition, in conventional dishwashers, there are also dishwashers that raise and lower the upper basket, but in order to move the upper basket up and down, there are many things that are provided with a plurality of rail parts on the upper and lower sides of the upper basket, so On the other hand, there has been a problem that the set space is reduced, and the mechanism for vertically moving the upper basket is expensive. In addition, depending on the size of the tableware, it takes time and effort to move the upper basket up and down, and on the contrary, it takes time to set the tableware.

  The present invention solves the above-described conventional problems, and without increasing the size of the washing tank, the basket is rotated in the vertical direction with an inexpensive and simple structure so that the dishes having a large diameter, An object of the present invention is to provide a dishwasher with excellent setability of tableware by securing a set space for setting tableware such as long cups.

In order to solve the above-described conventional problems, a dishwasher of the present invention includes a washing tank having a wall surface formed of resin and having an opening in the front, and a fixed nozzle that is formed of resin and injects washing water for washing dishes. a main basket for containing the dishes provided in a lower portion in the cleaning tank, and sub-basket for containing the dishes in the size of the lateral direction substantially 1/2 of disposed rearward above the main car the main car , and a plurality of support members for supporting the rear end of the auxiliary basket is provided in two places between the back side and the side surface rear of the washing tub as rotating fulcrum, the wall surface of the one with the side surface of the cleaning tank of the support member And the other of the support member and the fixed nozzle are integrally formed of resin, and the fixed nozzle is provided at a substantially intermediate point in the left-right direction of the inner surface of the back surface of the cleaning tank. the basket, the pivot point of the supporting member of the two portions For example, when setting large dishes that cannot be accommodated in the set space of the lower basket of the main basket, the front end of the upper basket of the secondary basket is set upward from the original position. When it rotates, the set space in the lower car becomes larger, and when it is turned downward from the initial position, the set space of the upper car becomes larger. Therefore, it becomes possible to set large tableware that cannot be accommodated in the initial upper and lower basket setting spaces, and the setability of the tableware is significantly improved without enlarging the washing tank. In addition, since the wall surface of one support member and the washing tub is integrally formed of resin and the other support member and the fixed nozzle are integrally formed of resin, new mold costs and assembly costs for the support member are also required. Does not occur. Therefore, it is possible to improve the setability of tableware with a simple and inexpensive configuration.

  In the dishwasher of the present invention, the rear end of the secondary basket is rotatably supported by a support member provided on the wall surface of the cleaning tank without increasing the size of the cleaning tank. By rotating the front part of the container in the vertical direction, it is possible to increase the required space for setting the basket and improve the setability of the tableware.

A first aspect of the present invention is a cleaning tank having a wall surface formed of a resin and having an opening in the front, a fixed nozzle that is formed of a resin and injects cleaning water for cleaning dishes, and is provided at a lower portion in the cleaning tank. A main basket for storing dishes, a secondary basket that is arranged at the upper rear of the main basket and stores dishes with a size approximately ½ of the horizontal direction of the main basket, a rear side and a rear side of the washing tank, the support together with the sub-cage rear is provided in two locations and a plurality of support members for supporting a rotating fulcrum, and a wall of one the side surface of the cleaning tank of the support member is formed integrally with resin The other of the members and the fixed nozzle are integrally formed of resin, the fixed nozzle is provided at a substantially middle point in the left-right direction of the inner surface of the back surface of the cleaning tank, and the auxiliary basket is rotated around the two supporting members. As a moving fulcrum, it can be turned up and down, for example For example, when setting large tableware that cannot be accommodated in the set space of the lower basket of the main basket, turning the front end of the upper basket of the sub basket upward from the original position will increase the set space in the lower basket. Rotating downward from the initial position increases the set space for the upper basket. Therefore, it becomes possible to set large tableware that cannot be accommodated in the initial upper and lower basket setting spaces, and the setability of the tableware is significantly improved without enlarging the washing tank. In addition, since the wall surface of one support member and the washing tub is integrally formed of resin and the other support member and the fixed nozzle are integrally formed of resin, new mold costs and assembly costs for the support member are also required. Does not occur. Therefore, it is possible to improve the setability of tableware with a simple and inexpensive configuration.
In addition, a combination of a support member formed integrally with the wall surface of the cleaning tank and a support member formed integrally with the fixed nozzle can be formed with a simple and inexpensive configuration even if the size and position of the upper basket changes. It is. For example, if you want to provide an upper basket that is 1/2 the size of the lower basket in the left-right direction on the left rear side of the cleaning tank, a support member is provided on the left side wall of the cleaning tank, and a fixed nozzle is provided on the right side of the upper basket. If the member is configured, the support member of the upper basket can be configured with a simple configuration. Further, if a support member is provided on the right side surface of the cleaning tank, the user can change the position of the upper basket to the right rear of the cleaning tank, which further improves usability.

In the second invention, in particular, the width in the front-rear direction of the secondary car of the first invention is configured to be ½ or less of the width in the front-rear direction of the main car. The upper car is centered on the support member. As a result, the space in the height direction of the lower car opens greatly. If the width in the front-rear direction of the upper basket is 1/2 or more, the rotation angle becomes small, so the space in the height direction of the lower basket becomes small, and large dishes cannot be set. In addition, in the conventional dishwasher, when setting tableware behind the lower basket, there is a problem that the upper basket is in the way and it is difficult to set the dishes. However, according to the present invention, since the width of the upper basket in the front-rear direction is less than half of the width in the front-rear direction of the lower basket, the user sets the tableware in the lower basket below the upper basket. There is no problem that the upper basket gets in the way and is difficult to set. In addition, there is no need to pull the lower basket forward.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a side sectional view of the dishwasher according to the first embodiment of the present invention, and FIG. 2 is a front view of the dishwasher. This embodiment is different from the conventional example only in the shape and attachment method of the upper basket, and the same parts as those in the conventional example are denoted by the same reference numerals, and the description thereof is omitted.

  1 and 2, the dishwasher according to the present embodiment includes a lower basket 5 made of a rod-shaped wire rod as a main basket for storing tableware 10, and a resin-made secondary basket behind and above the lower basket 5. The upper basket 15 is provided. The size of the upper basket 15 is approximately half the size of the lower basket 5 in both the left-right direction and the front-back direction. A wall surface of a fixed nozzle 18 that supports the upper basket 15 and serves as a rotation fulcrum at the rear side of the left side of the cleaning tank 1 and the substantially intermediate point in the left-right direction of the back inner surface of the cleaning tank 1. Are provided at two locations. Further, a support member C19 for supporting the upper basket 15 is further provided at an intermediate point in the front-rear direction of the left side surface of the cleaning tank 1. The support members A16 and C19, the wall surface of the cleaning tank 1, the support member B17, and the fixed nozzle 18 are all integrally formed of resin. Other configurations are the same as those of the conventional example, and thus the description thereof is omitted.

  The usage method of the upper basket 15 of the dishwasher comprised as mentioned above is demonstrated.

  The upward rotation of the upper basket 15 is performed by the support members A16 and B17 that also serve as rotation fulcrums. The upper basket 15 at the initial position before rotation is supported at three points: support members A16 and B17 provided on the wall surface of the cleaning tank 1 and the wall surface of the fixed nozzle 18, and a support member C19 provided on the side surface of the cleaning tank 1. ing.

  In this embodiment, the tableware 10 is set in the upper basket 15 in this state. Moreover, when setting the large tableware 10 which cannot be accommodated in the set space of the lower basket 5, if the upper basket 15 is rotated upward from the initial position, the set space in the lower basket 5 becomes large. Therefore, the large tableware 10 which cannot be accommodated in the set space of the lower basket 5 can be set, and the setability of the tableware 10 is remarkably improved without enlarging the washing tank 1.

Moreover, the supporting members A16 and C19 and the wall surface of the cleaning tank 1, the supporting member B17 and the fixed nozzle 18
Are integrally formed of resin, so that new mold costs and assembly costs of the support members A16, B17, and C19 do not occur. Therefore, in this embodiment mode, it can be formed with a simple and inexpensive configuration. In the present embodiment, the upper basket 15 is rotated around the support members A16 and B17. However, if the upper cage 15 is moved up and down, the tableware 10 can be set even when moved upward. .

  The support members A16, B17, and C19 can be formed in the lower cage 5. However, in order to form the support members A16, B17, and C19 on the upper portion of the lower cage 5, This method is not good because the wall surface and the like need to be raised to the position of the upper basket 15 and the cost of the constituent members and the lower basket 5 increases.

  Further, if a support member is further provided on the right side surface of the cleaning tank 1, the user can change the position of the upper basket 15 to the right rear side of the cleaning tank 1, and the usability is further improved.

  Further, as shown in FIG. 3 (a), the width of the upper basket 15 in the front-rear direction is set to approximately ½ or less of the width of the lower basket 5 in the front-rear direction, whereby the upper basket 15 is supported by the supporting members A16, B17. , The upper basket 15 is located in the upper rear part of the cleaning tank 1, so that the space in the height direction of the lower basket 5 is greatly opened. Moreover, since most of the tableware 10 is substantially circular, the rear upper part of the cleaning tank 1 is not necessary as a set space. Therefore, the large tableware 10 can be set. As shown in FIG. 3B, if the width of the upper basket 15 in the front-rear direction is 1/2 or more of the width of the lower basket 5 in the front-rear direction, the rotation angle of the upper basket 15 becomes smaller. The space in the height direction of the basket 5 becomes small, and the large tableware 10 cannot be set.

  However, in the present embodiment, since the width of the upper basket 15 in the left-right direction is also about ½ of the width of the lower basket 5, the upper portion of the lower basket 5 opposite to the upper basket 15 has a large space and a larger space. The merit that the tableware 10 can be set also arises.

  Moreover, in the conventional dishwasher which has the opening part 1a, when a user sets the tableware 10 in the back position of the lower basket 5, the upper basket 4 becomes obstructive and it is difficult to set the tableware 10. However, in this embodiment, the width of the upper basket 15 in the front-rear direction is less than half the width of the lower basket 5 in the front-rear direction. Therefore, when the user sets the tableware 10 in the lower basket 5 below the upper basket 15, there is no problem that the upper basket 15 gets in the way and is difficult to set.

  In addition, there is a merit that it does not take time to pull the lower basket 5 forward. In addition, this Embodiment is especially useful in the dishwasher which has the opening part 1a ahead.

  As described above, according to the present embodiment, even if the washing tank 1 is not enlarged, the upper basket 15 of the secondary basket can be rotated with a simple structure and cannot be accommodated in the initial set space of the lower basket 5. Large tableware 10 can be easily set. Therefore, the setability of the tableware 10 is greatly improved. In addition, since the support members A16, B17, and C19 and the wall surface of the cleaning tank 1 are integrally formed of resin, new mold costs and assembly costs for the support members A16, B17, and C19 do not occur. Therefore, it can be formed with a simple and inexpensive configuration.

  As described above, the dishwasher according to the present invention can move the basket up and down with a simple structure without increasing the cost without enlarging the washing tank. Can be applied to household and commercial dishwashers.
