Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher including a dish basket that supports dishes.

  The dishwasher includes a washing tank and a dish basket that supports dishes in the washing tank. Examples of tableware to be washed by the dishwasher include large plates, medium bowls, small plates, bowls, and cooking containers (frying pans and pots) having different shapes. These tableware items are supported by the tableware basket by being set so that they are inserted between the support rods and support pins provided in the tableware basket, and are washed by being stored in the washing tank in this state. Be seen.

  The tableware basket includes a large number of support rods and support pins having different heights and bent shapes, and the region for supporting a given tableware is substantially determined by the size and spacing of the support rods and support pins.

  By the way, depending on the size and type of tableware, it does not match any of the support areas, so it is unavoidable that the tableware is intentionally set in the wrong position, or tableware with different shapes are randomly mixed and set in the tableware basket. There is a case to do. However, in this case, the washing water may not properly hit the dishes, and the washing efficiency may decrease.

  Therefore, there has been proposed a tableware basket in which the distance between adjacent support bars (supporting distance in the depth direction of the tableware) can be changed in a part of the tableware basket (see Patent Document 1 below). However, when the distance between the support rods is changed, it is only possible to cope with the large and small depth dimensions of plates, etc., and in most cases it is not possible to cope with the large and small outer diameters of tableware, so There is a problem that the dishes cannot be stably supported due to interference between the dishes and the inner wall surface of the cleaning tank.

  In addition to the above, a tableware basket has been proposed in which a small case is provided so as to be movable, and the small case covers a support member that supports some tableware or the like that is placed less frequently. 2).

  In this structure, when supporting tableware or the like having a low mounting frequency, the accessory case is moved to expose the support member supporting the tableware or the like having a low mounting frequency. However, the accessory case is formed in a relatively small size to stand up and support chopsticks, spoons, etc., and the area that can be covered up on the tableware basket is relatively small. Therefore, even if the accessory case is moved on the tableware basket, it is difficult to support, for example, tableware having a large outer diameter at the position.

  In view of the above points, an object of the present invention is to provide a dishwasher including a tableware basket that can efficiently support tableware having different sizes by efficiently using a tableware support space. To do.

  In order to achieve such an object, the present invention provides a dishwasher including a washing tank and a tableware basket provided inside the washing tank to support tableware, wherein the tableware basket is housed in the washing tank. A base frame and a tableware support member that is provided on the base frame and can support a plurality of tableware arranged in a sideways posture, and the base frame supports the tableware supported by the tableware support member. Is provided with a support member moving means that extends in the horizontal direction along the radial direction of the tableware so that the tableware supporting member can be arranged at any position in the horizontal direction. It is characterized by being provided.

  According to the present invention, when tableware having a relatively large outer diameter is supported by the tableware support member, each tableware support member is arranged at a position where the outer peripheral edge of the tableware does not interfere with other tableware or the inner wall surface of the washing tank. Thus, it can be expanded to a support space suitable for dishes with a relatively large outer diameter.

  Therefore, it is possible to efficiently use the supporting space for the tableware and easily support the tableware having a relatively large outer diameter.

  Further, in the present invention, it is preferable that the support member moving means is a rail that allows the tableware support member to be horizontally movable.

  By adopting the rail as the supporting member moving means, the tableware supporting member can be arranged at a desired position only by sliding the tableware supporting member along the rail while supporting the tableware. Thus, the tableware supporting members can be slidably moved in accordance with the outer diameter of the tableware supported by the tableware supporting member to easily adjust the positions and the supporting spaces of the tableware supporting members.

  Further, in the present invention, the tableware supporting member includes a latching claw protruding in a moving direction of the tableware supporting member, and the latching claw intersects a radial direction with an extending direction of the supporting member moving means. It is preferable that the edge of the tableware that is in the other horizontal posture in the direction of the movement is shaped so that it can be hooked.

  Supporting other tableware (for example, cookware with a large outer diameter such as a frying pan) in the space expanded by moving the tableware support member by providing a hooking claw that projects in the moving direction of the tableware support member You can

  Since the latching claw has a shape that allows the edge of the tableware to be latched in another sideways posture (that is, the direction different from the direction of the tableware arranged on the dishware supporting member), the latching claw is supported by the latching claw. The tableware to be formed has a different orientation from the tableware arranged in plural on the tableware support member. Accordingly, it is possible to support a relatively large tableware (for example, a frying pan) in a posture that does not hinder washing of a plurality of tableware arranged on the tableware support member. Therefore, according to the present invention, the support space for tableware can be used more efficiently.
