Description

  The present invention relates to a dishwasher basket for a dishwasher installed in a washing tank of a dishwasher.

  Conventionally, as this type of tableware basket, one having a lower basket and an upper basket provided above a rear portion of the lower basket is known from Patent Document 1. In this structure, the upper basket is slidably connected at the rear end portion to the first shaft portion provided at the upper end portion of the rising portion that is erected on both sides in the lateral direction of the rear portion of the lower cage, and stands upright. A main body part that can be raised and lowered to a position and a lying position that has fallen forward, and a rear shelf part that projects rearward from the rear end of the main body part when the main body part is in the lying position. The rear shelf portion is swingably connected at the front end portion to a second shaft portion provided at a portion of the main body portion located in front of the first shaft portion when the main body portion is set to the lying position.

  According to this, these tablewares are cleaned by placing the cup, cups, etc. on the front and rear shelves of the upper basket upside down and placing the table upside down on the front part of the main body. can do. Further, if the upper basket body is set to the upright position, the upper basket does not get in the way when setting tableware on the rear part of the lower basket. Here, when the main body is set to the upright position, the rear part of the rear shelf that projects rearward from the main body in the lying position hangs downward from the main body, but the rear shelf uses the second shaft as a fulcrum with respect to the main body. Because it is swingable, even when tableware hits the rear shelf when setting tableware on the rear part of the lower basket, it is pushed by the tableware and the rear shelf swings backward, making it impossible to set the tableware. There is nothing.

However, depending on the shape of the tableware, when the tableware is set on the rear portion of the lower basket, the tableware may be caught on the rear shelf. In this case, it is necessary to set the tableware after the rear shelf is swung back by hand, and the setting property of the tableware to the rear portion of the lower basket is deteriorated. In addition, when leftover food sticks adhere to the second shaft portion and the rear shelf portion does not swing smoothly, the main body portion falls forward when the tableware comes into contact with the rear shelf portion hanging from the main body portion, It may be difficult to set tableware at the rear of the lower basket.

The center nozzle 6 includes a lower half 61 and an upper half 62 inserted in the lower half 61 so as to be movable up and down. When the cleaning water is supplied from the cleaning / drainage pump 3, the center nozzle 6 swivels together with the lower nozzle 5 and moves upward by the upward movement of the upper half 62 due to water pressure. Then, washing water is ejected from a plurality of nozzle holes 62 a formed in the upper half portion 62 of the center nozzle 6. In addition, a nozzle hole 61a is formed at the upper end of the lower half portion 61 of the center nozzle 6 for injecting cleaning water toward the downward opening end of the tableware W placed upside down on the upper basket 42. Yes.

  Referring also to FIGS. 2 and 3, the tableware basket 4 includes a lower basket 41 and an upper basket 42 provided above the rear portion of the lower basket 41. Rising parts 411 and 411 are erected on both lateral sides of the rear part of the lower basket 41. The upper basket 42 is swingably connected at a rear end portion to a lateral first shaft portion 412 provided at an upper end portion of the rising portion 411, and is placed between an upright position and a fall position that has fallen forward. A body part 43 that can be raised and lowered, a rear shelf part 44 coupled to the rear part of the body part 43, and a front shelf part 45 coupled to the front part of the body part 43 are provided. A rear guard 413 that supports the tableware W placed on the rear shelf 44 from the rear is provided between the rear ends of the compatible ascending portions 411 and 411 of the lower basket 41.

  The main body portion 43 includes a pair of left and right vertical bar portions 431 and 431 bent in a waveform in the vertical direction, and a front portion of the tableware W placed on the rear shelf portion 44 laid horizontally between the vertical bar portions 431 and 431. It has the horizontal bar part 432 which mounts, and the intermediate | middle guard part 433 which supports the tableware W mounted in the front shelf part 44 from back. An engagement portion 434 for the first shaft portion 412 is formed at the rear end of each vertical bar portion 431, and the main body portion 43 is swingably connected to the first shaft portion 412 at the engagement portion 434. Further, a support portion 414 is provided at the front end of the rising portion 411 to support the main body portion 43 by abutting against the vertical bar portion 431 when the main body portion 43 is set to the lying position.

  Further, a bar 435 that is bent in a U-shape in the lateral direction is attached to a portion of the vertical bar portion 431 that is positioned in front of the first shaft portion 412 when the main body portion 43 is set to the lying position. The rear shelf portion 44 is swingably connected to the second shaft portion 436 in the lateral direction formed by the rod portion on the front side of the rod member 435 at its front end portion.

  The rear shelf part 44 includes a horizontal bar part 441 at the rear end, a pair of left and right vertical bar parts 442 and 442 extending forward from the left and right ends of the horizontal bar part 441, and between the vertical bar parts 442 and 442. It has a horizontal bar portion 443 on which tableware W to be placed on the rear shelf portion 44 is placed. An engaging portion 444 for the second shaft portion 436 is formed at the front end of each vertical bar portion 442, and the rear shelf portion 44 is connected to the second shaft portion 436 in a swingable manner at the engaging portion 444. When the main body 43 is set to the lying position, the rear shelf 44 is supported by the bar on the rear side of the U-shaped bar 435 and is held in a posture in which the tableware W can be placed. In this state, the rear shelf portion 44 projects rearward from the rear end of the main body portion 43.
