The upper surface 56f' and the left and right side surfaces 56g' 56h of the umbrella-shaped portion 56c at the right end of the lane 56b are formed. Here, the sealing portion 54 on the bottom structural member 41 is positioned above the air blowing port 57, and even if the washing water vent 57 is infiltrated, the washing water does not come into contact with the sealing portion. . Inside the opening 55a of the air blowing device 55, a sealing portion 54 of the bottom structural member 41 and the cleaning groove member 40 is disposed. Further, the upper end portion 56d of the air supply passage 56 is formed at a position higher than the air supply port 57, and even if a large amount of foam is generated due to misuse of the general detergent for the kitchen, the side of the running bead & air blowing device 55 can be prevented from leaking out. One thing. As shown in Fig. 4, the dishware container support portion 53 on which the tableware container 31 is placed and supported is provided in a plurality of places on the left and right sides of the bottom portion of the bottom portion of the cleaning tank 29. The dish container support portion 53 is divided into a support portion lower portion 53a provided in the bottom structural member 41 and a support portion upper portion 53b provided in the cleaning groove member 40. Next, as will be described later, the cleaning member member 40 is joined to the bottom member member 41, and as shown in Fig. 6, the support portion upper portion 53b is opposed to the upper portion of the support portion lower portion 53a to form a dish 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 set to be the same height as the lower portion 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 is formed outside the side wall portion 49, approximately at a position directly below the groove portion 43, and the track 12 201206383 is received. The weight of the cleaning tank 29 is supported by the 卩5〇. In addition to the rail receiving portion 5, the towel P extends the rib 50a downward, and covers the movable rail portion 3〇d of the rail 3〇 from the upper side and the outer side, and enhances the mechanical strength of the rail receiving portion 50. The lid body 37 is configured such that the washing water dripping from the outer wall of the washing tank member 4 is infiltrated into the rail 30. Yu. Further, the outer side of the sealing rib 44 at the lower end of the front and rear outer peripheral portions of the cleaning groove member 4 is placed, and the engaging portion 52 is ribbed downward. The outer periphery of the groove and the bottom of the bottom constituting member 41 is provided with a plurality of convexities, and the engaging portion 52 of the cleaning groove member 40 is formed with an engaging hole 2a at the position of the convex portion, and the member is formed from the bottom. A washing groove member 4' is inserted in the upper portion of the 41. The engaging portion 52 is elastically deformed, and the convex portion 51 is engaged with the engaging hole 52a', and the washing groove member 4G and the bottom forming member 41 are joined. In the joined state, the lower ends of the engaging portions 52 of the left and right side faces abut against the upper surface of the rail receiving portion 50. By forming the joint portion of the cleaning tank member 4A and the bottom member member 41 as described above, the two can be joined by a simple structure and can be prevented from dripping from the lid body 37 to the outer wall of the washing tank member 4A. The washing water penetrates into the portion of the second sealing member 42. Further, as shown in Fig. 5, the cross-sectional shape of the fixed rail portion 3〇e of the rail 3〇 is set so that the ridge portion 3〇b is provided outside the movable structure portion 3〇a, and the outer side thereof is made lower. The shape of the groove portion 3〇c. Then, the outer side of the lower end of the rib 5a provided at the outer end portion of the rail receiving portion 5 of the bottom structural member 41 is positioned directly above the raised portion 30b or outside. With such a configuration, the outer wall of the tank member 40 is washed from the lid body 37.

13 201206383 The washing water dripped to the outside of the lower end of the rib 50a is guided to the groove portion 3〇c to prevent penetration into the movable structural portion 30a of 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 dripped and guided washing water 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; wherein the bottom constituting member 41 is attached with the second sealing member 42. As a result, the card hole 52a is engaged with the convex portion provided in the bottom structural member 41 and controlled in the vertical direction, and the cleaning groove member 40 and the bottom structural member 41 are combined and formed. At that time, the sealing ribs 44 of the cleaning tank member 4 are pressed from above by the second dam member 42 to be deformed to a predetermined closed position to seal the joint portion. Since the cleaning tank 29 is formed in the same manner, the cleaning groove member 4 〇 the rib 45 and the groove portion 43 of the bottom constituting member 41 are formed in the recovery space 46, and here, the second is The sealing member 42 is configured as an elastic body, and it is also possible to seal the water with a material such as a polyoxygenated adhesive. Since the above-described cleaning groove member 40 is combined with the bottom structural member 41, the lower divided passage 56a and the upper divided passage 5 6b are also combined. Next, the formation of the air supply passage 56 and the sealing of the air supply passage 56 are performed. The formation of the weir 54 and the formation of the air supply port 57, and the connection of the air supply passage 56 and the air blowing device 55 are connected. 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 member recovery space 46 becomes smaller than the size of the main space 46b of the upper recovery space 14 201206383 46. Reducing the infiltration of water from the space. Further, since the lower end position of the shielding rib 45 is higher than 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', so that the washing water is not prevented from being recovered. Further, it is possible to suppress the occurrence of the special odor, and the lower end of the shielding rib 45 is formed so as to be located below the injection hole 48 of the cleaning nozzle 32, and the washing water sprayed from the injection hole 48 can be borrowed. The shielding ribs 45 are surely shielded. Therefore, the inlet 46a of the recovery space 46 is a washing water that is only in contact with the falling from the upper side of the washing tank 29, and the water flow with the pressure does not reach the groove portion 43. From the injection hole 48 The jetted water is dropped as it hits the tableware 28 or flows down the side of the washing tank member 4 to the lower end of the shielding rib 45. Since the front end of the shielding rib 45 is configured as The cleaning tank 29 surrounds the entire circumference of the cleaning tank 29 so as not to be positioned further outward than the inverted portion 49 of the bottom member member 41, and the washing water flowing down from the upper portion along the shielding ribs 4 does not penetrate into the recovery space 46' but to the bottom. The bottom surface of the constituent member 41 is recovered. Further, since the shielding ribs 45 on both sides of the washing tank 29 are not provided with a height difference from the inner wall 40a of the washing tank member 40, there is no unnecessary height difference, and the washing speed of the washing water is not lowered. Can enhance the art of craftsmanship. Further, while the bottom structural member 41 is joined to the cleaning groove member 40, the sealing portion 54 and the recovery space 46 of the joint portion are formed by water sealing, and the joining operation and the formation of the sealing portion 54 and the recovery space 46 are simplified. It can improve the fitting workability.

15 201206383 Even if the gap of the collection 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 arrives. The condition of the groove portion 43. According to the present invention, since the recovery space 46 between the shielding rib 45 and the groove portion 43 is set to a gap that does not cause the washing water to be sucked up by the capillary phenomenon, even if the washing water contacts the inlet 46a of the recovery space 46, There is no case that the washing water is sucked up to the ditch 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, and even if the second sealing member 42 is not formed, water leakage from the joint portion is not caused. 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 leaks out of the washing chamber 29. For this reason, in the present invention, the second sealing member is disposed above the outer side of the recovery space 46. In addition, since the second sealing member 42 is not leaked even if the second sealing member 42 is not provided, the second sealing member 42 is deteriorated due to the long-term use, and vibration and force are repeatedly applied to the groove portion 43 by the pulling operation. The resulting seal is low and there is no water leakage. Since the recovery space 46 is formed so as to surround the entire circumference of the cleaning tank 29, the washing tank 29 is pulled out and operated in a strong manner, and the washing water is higher than the predetermined washing water level 47. Then, even if the washing water permeates into the recovery space 46' 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 there is no possibility of water leakage. 16 201206383 As described above, in the present embodiment, the sealing portion 54 is provided, and the second sealing member 42 having the water sealing portion 54 is provided, and the sealing portion 54 is used for water sealing to cover the upper end portion of the member 41 and the bottom portion. A joint portion formed by the lower end portion of the clean groove member 4〇. Next, 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, which prevents the washing water from rising due to capillary action. And arrived at the sealing part 54- thing. Therefore, under normal use, the washing water does not reach the sealing portion 54, and the fourth sealing member 42 is not fresh (4) because of the use of the pulling (4) and the length (4). In the washing tank of the conventional dishwasher, if the dish container support portion is formed into a tongue formed integrally from the bottom member member 41 and standing on the upper side, as seen in Fig. 6, it can be easily analogized with the tableware. An opening gap is formed between the container support portion 53 and the shielding rib 45. Therefore, the sprayed washing water easily permeates into 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 the support portion lower portion 53a and the upper portion of the support portion, and the lower portion of the support portion is provided on the bottom structural member 4, and the upper portion of the support portion is hungry and cleaned. The trough member is such that it faces above the lower portion of the support. And: owing, the lower part of the shielding rib is slightly the same as the height by the height position of the dividing surface, and the lower part of the supporting part of the bottom constituting member 41 is disposed on the cleaning groove member The gap between the upper portion 53b of the support portion of the 4G is opened in the K-flat direction. Therefore, it is difficult to wash the water to the gap, and it is expected to be washed under the water droplets and returned to the washing tank. On the side, it is possible to prevent the washing water from flowing from the tableware holding support portion 3 to the person collecting space 46.

17 201206383 In addition, 'the cleaning of the trough member 40 and the bottom constituting member 41' is taken into the bottom of the constituting member 41 ^ part of the dividing passage: and the material is formed in the washing trough member Also combined with the body. Thereby, since the air supply passage 56 is formed and invades into the air supply passage, the washing water contacts the welded portion and the joint portion, and can be collected into the washing tank 29. Therefore, even if it is used for a long period of time, it is possible to prevent the washing water that has entered the air blowing passage 56 from leaking out of the washing tank 29. Hurricane vent 5 7 is also due to the lower split passage 5 6 & and the upper split passage 56t> card. Further, it is formed so that the connection between the thin 57 and the air supply passage 56 can be prevented, and the washing water can be prevented from leaking out of the washing tank 29 from there. The air blowing port 57 that connects the cleaning groove member 40 and the bottom constituting member 41 to the air blowing passage 56 is configured to blow air toward the heating device 33 (see FIG. 1), and the outside air can be heated and the tableware can be heated. Class 28 is dry. Therefore, the drying performance can be improved. At this time, the outside air sent from the air blowing device 55 is sent to the heating device I 33 in a state where the umbrella portion 56c is rectified, so that the outside air can be efficiently heated. The airflow of the outside air flowing through the air passage 56 is provided with a structure such as a rib in the lower divided passage 56a, the upper divided passage 56b, and the umbrella-shaped portion 56c, and the airflow toward the heating device 33 is adjusted to further efficiently heat. Further, since the umbrella-shaped portion 56c is formed integrally with the cleaning groove member 4 without a gap, it is not necessary to care for the washing water falling from above the washing tank 29 to enter the air blowing passage 56. Since the upper end of the bottom structural member 41 is formed at a position higher than the air supply port 57, the washing water permeating from the air blowing port 57 does not have a direct contact and a joint portion, and the water leakage can be eliminated even in a long-term use. 18 201206383 The sealing portion 54 of the bottom structural member 41 and the cleaning groove member 40 is positioned outside the air blowing passage 56. Therefore, the foam is generated in the washing tank 29 by the foodstuff and the detergent, and even if the foam penetrates from the air blowing port 57, the water leakage can be prevented. On the other hand, since the bottom portion constituting member 41 and the sealing portion 54 of the cleaning tank member 40 are disposed inside the opening 55 & of the air blowing device 55, the washing water does not enter the air blowing device 55. Further, since the upper end portion 56d of the air supply passage 56 is formed at a higher position than the air supply port 57, the foam can be prevented from being blown toward the air blowing device 55 even if a large amount of foam is generated due to the use of the general detergent for the kitchen. The side is out of the situation. Further, in the present embodiment, the side surface of the bottom member constituting member 41 which is a lower member of the cleaning tank 29 which is formed by the upper and lower joining is configured to have the weight receiving portion 50 for supporting the weight of the washing tank 29. By this configuration, the weight of the clean groove 29 and the other members are applied in the 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, the bottom structural member 41 is unitized by loading a large number of electronic components and structural members, and the portion of the sealing material (four) of the cleaning tank 40 is enlarged, and the small Wei is even at the bottom. It is also possible to obtain a washing tank having a different capacity by using a single member of the constituent member 41. Therefore, it is possible to make it easy to produce a tableware washing machine having a different washing tank capacity, and to improve the manufacturing efficiency. Further, in the present embodiment, it has been described that only the cleaning nozzle 32 which is freely rotatable is provided in the bottom portion of the cleaning tank 29. However, for example, even if the inner portion of the clean groove 29 is further provided with a separate washing nozzle, the basis can be obtained.
