At this time, the circulation pipe (not shown) is provided so that cleaning water can be supplied to the water supply pipe 52 connected to the injection nozzle 51.
[0014]
The cleaning water sprayed from the spray nozzle 51 by such a structure is sprayed to the basket 40 side to clean the tableware in the basket 40, and then collected on the bottom surface of the cleaning tank 30, and the water collecting tube (not shown). ), And is sent to the water suction pipe 52 through a water collection pipe (not shown) and a circulation pipe (not shown) by the operation of a circulation pump (not shown), and then supplied to the injection nozzle 51 for washing. Circulate inside the machine. Thus, the wash water circulating inside the washing machine is drained to the outside of the washing machine along the drain pipe (not shown) by the action of a drain pump (not shown) after a lapse of a predetermined time.
[0015]
On the other hand, in the dishwasher according to the present invention, the door 20 is formed such that its height is shorter than the depth of the washing tub 30, which is a more compact type by lowering the height of the dishwasher. To get a dishwasher. For reference, the depth of the cleaning tank 30 means the length from the front surface to the rear surface of the cleaning tank 30.
[0016]
Due to the height of the door 20, the basket 40 cannot be sufficiently pulled out of the cleaning tank 30 while being supported on the upper surface of the opened door 20. The dishwasher according to the present invention is provided by the three-stage sliding rail 60 installed between the inner wall of the washing tub 30 and the basket 40 so that the basket 40 is sufficiently drawn out of the washing tub 30. However, even if not supported by the upper surface of the opened door 20, it is provided so as to be sufficiently drawn out of the cleaning tank 30.
[0017]
The three-stage slide rail 60 is a multi-stage slide rail provided in a telescopic manner. As shown in FIGS. 3 and 4, both side surfaces of the basket 40 and the interior of the cleaning tank 30 corresponding thereto are provided. A pair is installed between the two side surfaces. The three-stage slide rail 60 includes a first rail 61 fixed to the side surface of the basket 40, a third rail 63 fixed to the inner surface of the cleaning tank 30, and the first rail 61 and the third rail 61. A second rail 62 provided between the rail 63 and the rail 63 is included. At this time, the third rail 63 is provided so as to accommodate the second rail 62 therein, and the second rail 62 is provided so as to accommodate the first rail 61 therein.

Therefore, in such a state, water drops attached to the tableware in the basket 40 may drop on the floor surface of the kitchen space in which the dishwasher is installed to contaminate the kitchen. Therefore, in the dishwasher according to the present invention, the door 20 extends to the lower portion of the basket 40 as the basket 40 is pulled out, and blocks water drops dripping from the basket 40 onto the floor of the kitchen. A cover 70 is provided.
[0020]
The cover 70 includes a main body 71 slidably inserted into the door 20, and is locked to a tip of the basket 40 when the basket 40 is pulled out so that the main body 71 is pulled out together with the basket 40. And a locking portion 72 provided at the tip of the main body 71. In such a cover 70, when the basket 40 is extended so as to pass through the door 20, the locking portion 72 is locked to the tip of the basket 40. As the basket 40 is subsequently pulled out, the cover 70 is extended to the outside of the door 20 together with the basket 40 as shown in FIG. Thereby, the basket 40 of the dishwasher according to the present invention is sufficiently extended to the outside of the washing tub 30 even when it is not supported by the upper surface of the opened door 20 by the three-stage sliding rail 60, and It is possible to prevent water droplets from dropping from the basket 40 extended to the outside of the door 20 by the cover 70 onto the floor surface of the kitchen.
[0021]
The length of the cover 70 is provided so that the lower portion of the basket 40 can be blocked even when the basket 40 is pulled out in consideration of the maximum drawing length of the basket 40 by the three-stage slide rail 60. . The locking portion 72 is preferably provided so that it can be easily locked to the tip of the basket 40 when the basket 40 is pulled out.
[0022]
Further, in the present embodiment, the cover 70 is provided so as to be pulled out from the door 20 by the sliding method as described above, but unlike this, the door 20 is rotated by a rotating roller method such as a normal shutter. As long as the basket 40 is extended to the lower side of the basket 40 as the basket 40 is pulled out and water drops dripping from the basket 40 onto the bottom surface of the sink can be blocked, the structure may be provided in any structure.
[0023]
【The invention's effect】
As described above, according to the dishwasher according to the present invention, the basket 40 is installed on the wall surface of the washing tank 30 by the telescopic three-stage slide rail 60. Therefore, even if the basket 40 is not supported by the upper surface of the opened door 20, the basket 40 can be pulled out to the outside of the washing tub 30, whereby the height of the door 20 of the dishwasher is designed to be lower.
