On the outer peripheral lower end portions of the front and rear left and right of the washing tank member 40, sealing ribs 44 are provided. The sealing rib 44 is engaged with the groove portion 43 of the bottom structural member 41. The sealing ribs 44 press the second sealing member 42 from above and cooperate with the groove portion 43 to exhibit watertightness. The shielding ribs 45 are provided to hang down on the inner side thereof. The shielding ribs 45 on the both side faces of the washing tank 29 are provided so as not to have a level difference from the side inner wall 40a of the washing tank member 40.

The outer peripheral upper end portion of the bottom structural member 41 and the outer peripheral lower end portion of the washing tub member 40 are joined together in the up-and-down direction. On the other hand, the joint portion is provided with the seal portion 54 and is hermetically sealed. The seal portion is composed of the groove portion 43, the seal rib 44, and the second seal member 42. Next, between the shielding rib 45 and the groove portion 43, the recovery space 46 is provided to surround the entire circumference of the cleaning tank 29, and the sealing property of the joint portion is maintained. Further, the space 46 is recovered to prevent the washing water from reaching the sealing portion 54 due to an increase in capillary action. At this time, the gap between the front end of the shielding rib 45 and the bottom constituting member 41, that is, the size of the inlet 46a of the recovery space 46 is configured to be smaller than the main space 46b of the upper recovery space 46.

Further, the front end of the shielding rib 45 is configured to be positioned above the predetermined washing water level 47 and below the plurality of injection holes 48 of the washing nozzle 32, and is configured not to be constituted by the bottom member. The position of the rebound water flowing from the washing water on the bottom surface of the 41. Further, the front end of the shielding rib 45 is formed so as to surround the entire circumference of the cleaning tank 29 and is not positioned outside the side wall portion 49 of the bottom member member 41.

Generally, in the dishwasher, the special lotion is dissolved in water to wash the dishware 28. However, the wettability of the surface of the washing tank 29 is caused by the components such as the surfactant contained in the lotion. Significantly rises. When the wettability is increased, a very strong capillary phenomenon occurs, and the width of the recovery space 46 (main space 46b) is wider than when normal water is targeted. The recovery space 46 is formed around the entire circumference of the washing tank 29 and is in a communicating shape. In other words, the shape of the storage space 46 in the cross-sectional shape shown in Fig. 4 is removed from the dish container support portion 53, and the entire circumference of the cleaning tank 29 is substantially the same shape.

As shown in FIG. 3, in the vicinity of the left and right side walls of the bottom in the washing tank 29, the dishware container support part 53 which mounts and supports the tableware container 31 is provided in several places on the left and right. The dish container support portion 53 is divided into a support portion lower portion 53a provided in the bottom structure member 41 and a support portion upper portion 53b provided in the cleaning groove member 40. Next, as will be described later, the cleaning groove member 40 is joined to the bottom structural member 41, and as shown in Fig. 5, the support portion upper portion 53b is opposed to the support portion lower portion 53a and can be formed into a tableware. Container support portion 53. Further, the height position of the lower surface 53c of the support portion upper portion 53b of the divided surface is substantially the same height as the lower end of the shielding rib 45 of the cleaning groove member 40.

Further, on both side faces of the bottom structural member 41, the rail receiving portion 50 that supports the weight of the cleaning groove 29 is formed outside the side wall portion 49, and is almost the portion where the groove portion 43 is directly below. On the outer end portion of the rail receiving portion 50, the rib 50a is provided to extend downward to cover the movable rail portion 30d of the rail 30 from above and outside, and to enhance the mechanical strength of the rail receiving portion 50 and prevent the slave body from being covered. The washing water dripping from the outer wall of the washing tank member 40 penetrates into the rail 30.

The engaging portion 52 is extended downward in a rib shape on the outer side of the sealing rib 44 provided at the lower end of the front, rear, left and right outer peripheral portions of the washing tub member 40. On the outer circumference of the groove portion 43 of the bottom structural member 41, a plurality of convex portions 51 are provided, and the engaging portion 52 of the cleaning groove member 40 is formed with an engaging hole 52a at a position corresponding to the convex portion 51, and a member is formed from the bottom portion. The cleaning groove member 40 is inserted into the upper portion of the 41, whereby the engaging portion 52 is elastically deformed, and the convex portion 51 is engaged with the engaging hole 52a, and the cleaning groove member 40 is joined to the bottom structural member 41. Next, in a state where the cleaning groove member 40 is joined to the bottom structural member 41, the lower ends of the engaging portions 52 of the right and left side faces abut against the upper surface of the rail receiving portion 50. By combining the cleaning groove member 40 and the bottom constituting member 41 as described above, it is possible to prevent the washing water from dripping from the lid body 37 to the outer wall of the washing tank member 40 with a simple configuration. The portion of the second sealing member 42 is infiltrated to maintain the sealing property of the joint portion.

Further, as shown in Fig. 4, the cross-sectional shape of the fixed rail portion 30e of the rail 30 has a raised portion 30b on the outer side of the movable structure portion 30a, and a groove portion 30c recessed from the raised portion 30b on the outer side. The outer side of the lower end of the rib 50a provided at the outer end portion of the rail receiving portion 50 of the bottom structural member 41 is positioned directly above the raised portion 30b or outside. In this manner, the washing water dripped from the outer wall of the lid body 37 through the outer wall of the washing tank member 40 to the lower end of the rib 50a is guided to the groove portion 30c to prevent the movable structural portion 30a from penetrating into the rail 30. Further, although not shown in the drawings, a through hole is provided in the rear of any of the movable structural portion 30a and the groove portion 30c, and the washing water that has been dripped and guided is dropped to the inner bottom portion of the casing 27, and can be made available. It is detected by a water leakage detecting sensor disposed in the vicinity thereof.

The operation and action of the dishwasher according to the above configuration will be described below. In the cleaning tank 29, the cleaning groove member 40 is inserted from above the bottom constituting member 41, and the engaging portion 52 is temporarily deformed by its own elasticity, and the engaging hole 52a is engaged with the cleaning hole 52a. The convex portion of the groove member 40 controls the movement of the cleaning groove member 40 and the bottom member member 41 in the vertical direction; wherein the bottom member member is attached with the second sealing member 42. In this way, the cleaning groove member 40 is integrated with the bottom structural member 41. At that time, the sealing rib 44 of the cleaning groove member 40 presses the second sealing member 42 from above and deforms it to a predetermined closed position to seal the joint portion. The cleaning groove 29 is integrated, and the storage space 46 is formed by the shielding rib 45 provided in the cleaning tank member 40 and the groove portion 43 of the bottom structural member 41. Further, here, although the second sealing member 42 is used as an elastic body, it is also possible to water-sealing with a material such as an organic binder.

The shielding ribs 45 provided on the inner side of the groove portion 43 are arranged such that the size of the inlet 46a of the recovery space 46 becomes smaller than the main space 46b of the upper recovery space 46, so that the infiltration of water into the recovery space 46 can be reduced. Further, since the lower end of the shielding rib 45 is positioned above the predetermined washing water level 47, foreign matter, oil, and the like flushed from the tableware 28 do not accumulate in the recovery space 46, and thus the washing water is not prevented from being recovered. Moreover, the occurrence of abnormal odor or the like can be suppressed.

Further, the lower end of the shielding rib 45 is positioned lower than the injection hole of the cleaning nozzle 32, and the washing water sprayed from the injection hole 48 can be surely shielded by the shielding rib 45. Therefore, in the inlet 46a of the recovery space 46, only the washing water having a small momentum falling from above the washing tank 29 is contacted, and the water flow with the pressure does not reach the groove portion 43.

The washing water sprayed from the injection holes 48 is dropped as it hits the tableware 28, or flows down the side surface of the washing tank member 40 toward the lower end of the shielding rib 45. At this time, since the front end of the shielding rib 45 surrounds the entire circumference of the cleaning tank 29 and is located inside the side wall portion 49 of the bottom structural member 41, the washing water flowing down from the shielding rib 45 from above does not penetrate into the recovery space. 46, but flows to the bottom of the bottom member member 41.

Further, since the lower end of the shielding rib 45 is positioned above the predetermined washing water level 47, foreign matter and oil which are washed out from the tableware 28 do not accumulate in the recovery space 46, and the washing water is not prevented from being recovered. Moreover, the occurrence of abnormal odor or the like can be suppressed.

Further, since the shielding ribs 45 on both side surfaces of the cleaning tank 29 are provided so as not to have a height difference from the inner wall 40a of the cleaning tank member 40, the recovery speed of the washing water does not decrease because there is no unnecessary height difference. Can enhance the art of craftsmanship.

Further, the bottom constituting member 41 and the cleaning sump member 40 are joined together, and the sealing portion 54 and the recovery space 46 that seal the joint portion are formed, and the joining operation and the formation of the sealing portion 54 and the recovery space 46 are simplified. Improve the fit and workability.

Even in such a configuration, if the gap of the recovery space 46 (main space 46b) is narrowed, the washing water that touches the inlet 46a of the recovery space 46 is sucked up by the capillary phenomenon, and even reaches the groove portion 43. The situation. In this case, according to the present invention, the recovery space 46 between the shielding rib 45 and the groove portion 43 is provided with a slit which does not cause the washing water to be sucked up by the capillary phenomenon, even if the washing water contacts the recovery space 46. At the inlet 46a, there is no case where the washing water is sucked up toward the groove portion 43.

As described above, according to the present invention, the washing water sprayed from the washing nozzle 32 does not reach the groove portion 43. If the configuration of the second sealing member 42 is not provided, the sealing property of the joint portion can be maintained. However, when the washing water is heated, steam is generated and condensation is formed in the vicinity of the groove portion 43, and a small amount of water may be discharged outside the washing tank 29. Therefore, in the present invention, the second sealing member 42 is disposed above the outer side of the recovery space 46. In addition, since the second sealing member 42 is not provided with water, the second sealing member 42 is not deteriorated, and the vibration and force are repeatedly applied to the second sealing member 42 due to the pulling operation. The sealing property of the groove portion 43 is lowered, and the sealing property with respect to the joint portion can be maintained.

In addition, the recovery space 46 is configured such that the ring cleaning tank 29 is connected all the way, and the cleaning tank 29 is strongly pulled out by the momentum, and the washing water is heated above the predetermined washing water level 47 and washed. The purified water permeates into the recovery space 46, and by the communication space 46 that is connected, it is possible to greatly reduce the amount of washing water reaching the groove portion 43 because there is a space in which the washing water escapes in the lateral direction. Of course, even when the washing water reaches the groove portion 43, the second sealing member 42 is water-sealed, and the sealing property of the joint portion can be maintained.

As described above, the dishwasher of the present embodiment includes the second sealing member 42 having the sealing portion 54 and the water seal sealing portion 54 for sealing the upper end portion of the bottom member member 41 with the water seal. a joint portion formed by the lower end portion of the groove member 40. The cleaning groove member 40 is provided with a shielding rib 45 on the inner side of the sealing portion 54, and a recovery space 46 is provided between the sealing portion 54 and the shielding rib 45. In the use, the washing water does not reach the sealing portion 54, and the sealing property of the joint portion can be maintained even when the sealing property of the second sealing member 42 is lowered due to the use during the drawing operation and the long period of use. Further, if the recovery space 46 is formed to prevent the washing water from rising to the sealing portion 54 due to the capillary phenomenon, the sealing property can be maintained for a longer period of time.

Further, in the washing tank of the conventional dishwasher, when the dish container support portion 53 is integrally formed from the bottom member member 41 and stands above, the table container support portion 53 and the shielding rib 45 are provided. A slit is formed in the upper portion, and the jetted washing water easily enters the recovery space 46 from the slit through the inlet 46a. However, in the present embodiment, the dish container support portion 53 is divided into a support portion lower portion 53a and a support portion upper portion 53b. The support portion lower portion 53a is provided in the bottom portion constituting member 41, and the support portion upper portion 53b is provided in the cleaning. The groove member 40 is opposed to the upper portion 53a of the support portion, and the height position of the divided surface thereof is substantially the same height as the lower end of the shielding rib 45 of the cleaning groove member 40 because it is disposed at the bottom constituent member 41. The gap between the lower portion 53a of the support portion and the upper portion 53b of the support portion of the cleaning tank member 40 is formed substantially in the horizontal direction, and the washing water sprayed into the slit is hard to penetrate, and it is expected to be washed and dripped back. The washing tank 29 side is provided to prevent the washing water from flowing into the collecting space 46 from the dish container supporting portion 53.

Further, in the present embodiment, the side surface of the bottom member constituting member 41 of the lower member of the cleaning tank 29 which is formed by the upper and lower joining is formed by the rail receiving portion 50 which supports the weight of the cleaning tank 29, and does not The weight of the cleaning tank 29 and other members is applied in a direction in which the sealing portion 54 is pulled away, and the sealing property of the second sealing member 42 can be maintained for a long period of time.

Further, in the present embodiment, most of the electrical component and the component are mounted and unitized by the bottom structural member 41, and the portion larger than the sealing portion 54 of the cleaning groove member 40 is enlarged and miniaturized. Further, even if a single thing is used as the bottom constituting member 41, the washing tanks having different capacities can be obtained. Therefore, it is possible to easily produce a dishwasher having different washing tank capacities, and it is possible to improve the manufacturing efficiency.

Further, in the present embodiment, a dishwasher having a cleaning nozzle 32 that is freely rotatable in the bottom portion of the cleaning tank 29 is described. Further, for example, the inside of the cleaning tank 29 is further provided with a different portion.
