In the wash cycle, the circulation pump 93 may be activated to pump wash water from the sump 80. The washing water pumped by the circulation pump 93 may be distributed to the upper rotating nozzle 51, the middle rotating nozzle 52, and the fixed nozzle 53 through a distribution device (not shown). Due to the pumping force of the circulation pump 93, washing water is sprayed at high pressure from the plurality of spray nozzles 51, 52, and 53 to wash dishes.

The washing water sprayed from the plurality of spray nozzles 51, 52, and 53 hits the dishes, removes dirt from the dishes, and falls together with the dirt to be stored in the sump 80 again. The circulation pump 93 circulates the washing water stored in the sump 80 by pumping it again. During the cleaning cycle, the circulation pump 93 may repeat operation and stop several times. In this process, the dirt that falls into the sump (80) along with the washing water is collected by a filter mounted on the sump (80) and remains in the sump (80) without being circulated to the plurality of spray nozzles (51, 52, and 53). .

In the drain stroke, the drain pump 95 operates to drain the sewage remaining in the sump 80 and the washing water together to the outside of the main body 10.

In the drying process, a heater (not shown) mounted on the tub 20 is operated to dry the dishes.

Specifically, the blocking member body 210 extends from the first part 211 and is in close contact with the bottom plate 21 of the tub 20 depending on whether the door 30 is opened or closed. It may include a second part 212. More specifically, the second part 212 of the blocking member body 210 is in close contact with the bottom plate 21 of the tub 20 when the door 30 is closed, and is in close contact with the bottom plate 21 of the tub 20 when the door 30 is opened. It can be spaced apart from the bottom plate 21.

The second part 212 of the blocking member body 210 may extend obliquely from the first part 211 of the blocking member body 210. The second part 212 of the blocking member body 210 is operated so that it passes the boundary D between the first part 211 and the second part 212 when the door 30 is closed. The first part 211 of the blocking member body 210 is inclined toward the direction in which the engaging protrusion 220 extends from the blocking member body 210 with respect to the reference line L extending in the vertical direction (Z) of (1). ) can be extended from.

Explained from another aspect, the first part 211 of the blocking member body 210 may be in close contact with both side walls 21d and 21e of the bottom plate 21 of the tub 20 when the door 30 is closed. The second part 212 of the blocking member body 210 may be in close contact with the connection portion of the base 21a and the side walls 21d and 21e of the bottom plate 21 of the tub 20 when the door 30 is closed. . At this time, the connecting portion of the base 21a and the side walls 21d and 21e of the bottom plate 21 of the tub 20 may include a curved surface. When the door 30 is closed, the second part 212 of the blocking member body 210 may be in close contact with the base 21a from the connection portion of the base 21a and the side walls 21d and 21e.

By forming the second part 212 of the blocking member body 210 to be inclined from the first part 211 of the blocking member body 210, the sealing effect of the blocking member 200 can be maximized. That is, when the second part 212 of the blocking member body 210 is formed to be inclined from the first part 211 of the blocking member body 210, the rounded base 21a and the side walls 21d and 21e Adhesion of the second part 212 of the blocking member body 210 to the connection portion can be improved.

Figure 7 is a view showing a blocking member involved in blocking the gap between the door and the tub when the door of the dishwasher is closed according to an embodiment of the present invention, and Figure 8 is a view showing the appearance of a blocking member according to an embodiment of the present invention. This is a drawing showing what the blocking member looks like when the door of the dishwasher is open. For reference, FIG. 7 is a view showing part A of FIG. 1 viewed from the top, and FIG. 8 is a view showing part B of FIG. 2 viewed from the top.

As shown in FIGS. 7 and 8 , the blocking member 200 can selectively block the gap between the door 30 and the tub 20 depending on whether the door 30 is opened or closed. Explained from another aspect, the blocking member 200 can selectively connect the sealing member 110 and the packing member 120 depending on whether the door 30 is opened or closed.

As shown in FIG. 7, the blocking member 200 is connected to the door 30 and the tub ( 20) It is possible to close the gap between Specifically, when the door 30 of the dishwasher 1 is closed, the blocking member 200 moves integrally with the sealing member 110 between the lower end of the door 30 and the bottom plate 21 of the tub 20. The gap can be closed. Explained from another aspect, the blocking member 200 includes a sealing member 110 and a packing member ( 120) can be connected.

When the door 30 is closed, the blocking member body 210 may be in close contact with the bottom plate 21 of the tub 20. Preferably, the first part 211 of the blocking member body 210 is in close contact with the side walls 21d and 21e of the bottom plate 21, and the second part 212 of the blocking member body 210 is rounded. It can be in close contact with the connection portion of the side walls (21d, 21e) and the base (21a) of the bottom plate (21).

When the door 30 is closed, the first protruding rib 231 of the blocking member 200 may be disposed between the packing member 120 and the inner frame 32 of the door 30. Specifically, when the door 30 is closed, the first surface 231a of the first protruding rib 231 of the blocking member 200 is in close contact with the packing member 120, and the first protruding rib of the blocking member 200 The second surface 231b of 231 may be in close contact with the inner surface of the inner frame 32.

The blocking member 200 blocks the gap between the door 30 and the tub 20, which is difficult to block with only the sealing member 110 and the packing member 120, thereby preventing washing water from leaking to the outside of the dishwasher 1. It can be prevented more effectively. As an example, the blocking member 200 is the front corner portions 21m and 21n of the bottom plate 21 of the tub 20 and the door 30, which are difficult to block with only the sealing member 110 and the packing member 120. The gap between them can be effectively blocked.

As shown in FIG. 8 , the blocking member 200 may not be involved in blocking the gap between the door 30 and the tub 20 when the door 30 of the dishwasher 1 is opened. Specifically, when the door 30 of the dishwasher 1 is opened, the blocking member 200 moves integrally with the sealing member 110 to connect the lower part 33 of the door 30 and the bottom plate of the tub 20. (21) may not be involved in blocking the gap between them. Explained from another perspective, the blocking member 200 may not be involved in connecting the sealing member 110 and the packing member 120 when the door 30 of the dishwasher 1 is opened.

When the door 30 is opened, the blocking member body 210 may be spaced apart from the bottom plate 21 of the tub 20.

When the door 30 is opened, the first surface 231a of the first protruding rib 231 is spaced apart from the packing member 120, and the second surface 231b of the first protruding rib 231 is adjacent to the inner frame ( 32).

In the above, specific embodiments are shown and described. However, it is not limited to the above-mentioned embodiments, and those skilled in the art can make various changes without departing from the gist of the technical idea of the invention as set forth in the claims below. .
