  The present invention relates to a dishwasher comprising a washing tub in which a tableware basket that supports tableware is stored, a washing nozzle provided in the washing tub, and a washing pump that supplies washing water in the washing tub to the washing nozzle. About.

  Conventionally, as a dishwasher of this type, the washing nozzle has a center nozzle that is pushed upward by the water pressure of the washing water supplied from the washing pump, and the dish basket is in a state where the center nozzle extends upward. A device having an upper cage arranged at a position lower than the upper end of the center nozzle is known (see, for example, Patent Document 1). The upper basket can support tableware with a small diameter and a deep bottom, represented by a cup or a cup of water, in an attitude that is inclined in a direction away from the center nozzle with the opening edge down, and an opening that receives the opening edge of the tableware. It has a receiving part and a peripheral wall receiving part that receives a part of the peripheral wall part of the tableware in the direction of tableware inclination, so that cleaning water sprayed from a nozzle hole formed in the center nozzle enters the tableware.

  By the way, in order to reduce the size of the dishwasher, it may be required to shorten the horizontal distance between the center nozzle and the upper basket. In this case, when the tableware is placed at a position closest to the center nozzle of the upper basket, the portion of the tableware protruding from the side end of the upper basket near the center nozzle may interfere with the center nozzle extending upward.

  This invention makes it the subject to provide the dishwasher which made it possible to prevent that the tableware mounted in the upper basket interferes with the center nozzle extended upwards in view of the above point.

  In order to solve the above-described problems, the present invention supplies a cleaning tank in which a tableware basket supporting tableware is stored, a cleaning nozzle provided in the cleaning tank, and cleaning water in the cleaning tank to the cleaning nozzle. A dishwasher comprising a washing pump, wherein the washing nozzle has a center nozzle that is pushed upward by the pressure of washing water supplied from the washing pump, and the dish basket has a state in which the center nozzle extends upward In the case where the upper basket is disposed at a position lower than the upper end of the center nozzle, tableware placement restriction means is provided for preventing the tableware from being placed on a specific portion of the upper car. In this particular location, when tableware is placed here, the portion of the tableware that protrudes from the side edge of the upper basket near the center nozzle may interfere with the center nozzle that extends upward. Characterized in that it is a closest to point to Nozuru.

  According to the present invention, it is not possible to place tableware by the tableware placement restriction means provided here at the place closest to the center nozzle which is a specific place of the upper car. Therefore, it is possible to prevent a problem that the tableware interferes with the center nozzle extending upward, which occurs when the tableware is placed at a position closest to the center nozzle of the upper basket.

  In addition, the upper basket can support dishes with a small diameter and deep bottom, represented by cups and cups, with the opening edge down and tilted away from the center nozzle, and receives the opening edge of the tableware. In the case of having an opening receiving portion and a peripheral wall receiving portion that receives a portion of the peripheral wall portion of the tableware on the side of the tableware inclination direction, the tableware placement restricting means is provided at a part of the peripheral wall portion of the tableware at the specific location. And it should just be comprised with the baffle plate provided so that the part of the direction which cross | intersects the tableware inclination direction may contact | abut. According to this, since the peripheral wall part of tableware contacts a baffle plate, it becomes impossible to place tableware in the said specific location.

  The baffle plate is preferably provided so as to straddle both the opening receiving portion and the peripheral wall receiving portion. According to this, the baffle plate also functions as a reinforcing member that connects the opening receiving portion and the peripheral wall receiving portion, and the rigidity of the upper car is increased.

  If the height of the upper edge of the baffle plate is lower than the height of the upper end of the peripheral wall receiving portion, the tableware is mistakenly placed at a specific location with the peripheral wall portion of the tableware placed on the upper end of the peripheral wall receiving portion and the upper edge of the baffle plate. May be placed. Therefore, the height of the upper edge of the baffle plate is desirably equal to or higher than the upper end of the peripheral wall receiving portion. According to this, even if the peripheral wall portion of the tableware is placed on the upper edge of the baffle plate, the peripheral wall portion of the tableware is not placed on the upper end of the peripheral wall receiving portion, so the tableware is not stable and the tableware is erroneously placed at a specific location. Can be prevented.

  The dishwasher according to the embodiment of the present invention shown in FIG. 1 is a built-in type that is installed in a system kitchen and is housed in a housing 1 whose front surface is open so that it can be drawn out forward. It has. In the cleaning tank 2, a table basket 3 that supports tableware is stored, and a cleaning nozzle 4 that sprays cleaning water toward the tableware basket 3 is provided. A front lid 21 that closes the front surface of the housing 1 is attached to the front surface of the cleaning tank 2. In addition, a seal lid 11 that closes the opened upper surface of the cleaning tank 2 is provided in the upper part of the housing 1.

  At the bottom of the cleaning tank 2, there is provided a cleaning water reservoir 23 that communicates with the cleaning tank 2 through the leftover filter 22. A cleaning pump 5 that communicates with the reservoir 23 is installed below the bottom of the cleaning tank 2. When the cleaning pump 5 is rotated forward, the cleaning water in the cleaning tank 2 is supplied to the cleaning nozzle 4 via the reservoir 23 and the cleaning pump 5, and when the cleaning pump 5 is reversed, the cleaning water is It is made to drain from the washing tank 2.

  The cleaning nozzle 4 extends horizontally in the lower part of the cleaning tank 2, and can rotate around the vertical axis at the center in the longitudinal direction, and a center nozzle 42 erected at the center in the longitudinal direction of the lower nozzle 41. have. The lower nozzle 41 ejects cleaning water from the nozzle hole 411 formed in the lower nozzle 41, and rotates by this ejection reaction force. The center nozzle 42 includes a lower half portion 42a integrated with the lower nozzle 41, and an upper half portion 42b inserted in the lower half portion 42a so as to be movable up and down. When the cleaning water is supplied from the cleaning pump 5, the upper half 42 is pushed up by the water pressure of the cleaning water and the center nozzle 42 extends upward. Then, cleaning water is jetted from the nozzle holes 421 formed in the upper end portion of the lower half portion 42a and the nozzle holes 422 formed in the upper half portion 42b.

  The tableware basket 3 is disposed above the lower nozzle 41 and supports a relatively large tableware W1 such as a large plate, a small plate, a medium bowl, a bowl, and the center nozzle 42. It has an upper basket 32 which supports a tableware W2 having a small diameter and a deep bottom, which is typified by a cup or a cup of water, which is disposed at a position lower than the upper end of the center nozzle 42 when extended. A guard frame 311 surrounding the center nozzle 42 is provided at the center of the lower car 31 so that the tableware W1 placed thereon can be prevented from interfering with the center nozzle 42.

  Referring also to FIGS. 2 to 4, the upper basket 32 is engaged with and supported by the upper wall surface of the cleaning tank 2, and a frame body 321 made of a wire rod and a synthetic resin basket fixed to the frame body 321. The main body 322 is comprised. The car body 322 has two rows of tableware support portions 322a and 322b which are curved in the front and rear directions, and the tableware support portions 322a and 322b in each row can support a plurality of tableware W2 side by side. The tableware support portions 322a and 322b in each row can support the tableware W2 in a posture inclined toward the direction (backward) away from the center nozzle 42 with the opening edge down, and receive the opening edge of the tableware W2. And a peripheral wall receiving portion 324 formed of a single or a plurality of rod-shaped bodies that receive the rear side portion of the peripheral wall portion of the tableware W2.

  Here, in this embodiment, the horizontal distance between the center nozzle 42 and the upper basket 32 is shortened in order to reduce the size of the dishwasher. As a result, when the tableware W2 is placed at the position closest to the center nozzle 42 of the upper basket 32, that is, the horizontal center of the tableware support 322a in the front row, the side end of the upper basket 32 near the center nozzle 42, That is, the portion of the tableware W2 protruding from the front end may interfere with the center nozzle 42 extending upward.

  Therefore, in the present embodiment, tableware placement restriction means is provided that prevents the tableware W2 from being placed at the specific location, with the horizontal central portion of the tableware support portion 322a in the front row as the specific location. More specifically, a baffle plate 325 with which a lateral portion that is a direction intersecting the tableware inclination direction of the peripheral wall portion of the tableware W2 abuts is provided at a specific location. Is configured. According to this, since the peripheral wall portion of the tableware W2 comes into contact with the baffle plate 325, there is no space for placing the tableware W2 at the specific location, and the tableware W2 cannot be placed, so the tableware W2 is placed at the specific location. The problem that the tableware W2 interferes with the center nozzle 42 extending upward can be prevented.

  Moreover, in this embodiment, the baffle plate 325 is provided so that it may straddle both the opening receiving part 323 and the surrounding wall receiving part 324 of the tableware support part 322a of the front row. Thereby, the baffle plate 325 also functions as a reinforcing member that connects the opening receiving portion 323 and the peripheral wall receiving portion 324, and the rigidity of the upper car 32 is increased. Further, in the present embodiment, a hanging portion 325 a that engages with the horizontal bar portion 321 a of the frame body 321 is extended to the baffle plate 325 so that the support rigidity of the car body 322 can be increased.

  In addition, when the height of the upper edge of the baffle plate 325 is lower than the height of the upper end of the peripheral wall receiving portion 324, the peripheral wall portion of the tableware W2 is specified with being placed on the upper end of the peripheral wall receiving portion 324 and the upper edge of the baffle plate 325 There is a risk that the tableware W2 is erroneously placed in the place. Therefore, in this embodiment, the height of the upper edge of the baffle plate 325 is set to be equal to or higher than the upper end of the peripheral wall receiving portion 324. According to this, even if the peripheral wall portion of the tableware W2 is placed on the upper edge of the baffle plate 325, the peripheral wall portion of the tableware W2 does not rest on the upper end of the peripheral wall receiving portion 324, so the tableware W2 is not stable and is erroneously placed at a specific location Thus, it is possible to prevent the tableware W2 from being placed.
