Further, as shown in FIGS. 6 and 8, ribs 47 that pour water droplets 46 into the space between the upper door body 6 and the lid body 41 when the door body 5 is opened are formed on the left and right ends of the horizontally long lid body 41. Is extended longer than the lower end of the other part. The ribs 47 are provided adjacent to some of the plurality of holes 45 of the opening 42.

  Next, the operation and action in the above embodiment will be described. When installing a dishwasher, there are cases where the front of the dishwasher is placed toward the front along the side wall of the kitchen, and there are cases where the side is faced toward the front. In recent kitchens, a controller that centrally controls hot water supply facilities such as a bathtub and a water heater is generally installed on the side wall of the kitchen. When installing the dishwasher in the kitchen, there is no problem when the controller is installed at a position higher than the height of the main body 1 of the dishwasher, but when the controller is installed slightly lower, the display section provided on the controller In order to ensure the visibility and the operability of switches, the dishwasher must be installed away from the wall surface, which impairs the workability in the kitchen. And if the controller is installed lower, the dishwasher cannot be installed.

  However, according to the configuration of the present invention, the upper shape of the main body 1 is formed in a substantially arc shape that bulges upward from the front surface to the back surface, so that even when the controller is installed low, it can contact the controller. The main body 1 can be installed close to the wall surface. In addition, since the user can visually recognize the controller from above through the main body 1, the visibility of the display unit is obtained and the operability of the switches is also ensured.

  Thus, according to the present invention, the visibility and operability of the controller can be ensured and the installation property can be improved in a kitchen in which a controller such as a bathtub or a water heater is already installed.

  Further, the upper shape of the main body 1 and the upper shape of the upper door body 6 are formed in a substantially arc shape that bulges upward, and the upper door body 6 is moved along the arc-shaped portion 1c of the upper portion of the main body 1 to be cleaned. 2 is configured to open and close the opening 4 provided from the front surface to the upper surface, so that the height of the main body 1 when the opening 4 is opened can be kept low, and a hanging cabinet or the like is already installed. Installation in a place where the height of the space is low can be facilitated.

  Moreover, in the conventional dishwasher, since the shape seen from the side of the main body from the back surface to the upper surface of the washing tub 2 is substantially perpendicular, the washing water flowing from the back surface to the upper surface inside the washing tub 2 during washing. Is difficult to reach the top surface, and there is little washing water that pours onto the tableware from the top surface, so that the cleaning performance of dirt attached to the surface of the tableware is low, but according to the configuration of the present invention, the amount of washing water on the top surface of the washing tank 2 increases. Therefore, the amount of washing water that pours onto the tableware from the upper surface increases, and the dirt adhering to the surface of the tableware can be reliably washed away.

  The opening 4 is formed so as to include a front surface 1a of the main body 1 and an arc-shaped portion 1c provided so as to bulge outward from the front surface 1a to the upper surface. It is easy to take out and the setting property of the tableware is improved, and it becomes easy to install in a kitchen in which a controller such as a bathtub or a water heater is already installed.

  Further, the upper end 39 of the opening 4 provided on the upper surface of the cleaning tank 2 is formed so as to be positioned in the vicinity of the top 17 of the arcuate portion 1c that bulges upward, so that the upper area of the main body 1 is increased. Approximately half can be opened. For this reason, the field of view up to the back of the upper basket 9 is widened, and tableware can be easily put in and out. In particular, since the tableware basket 3 is configured so that the center of the dish 50 and the center of the arcuate portion 1c bulging upward from the front surface of the main body 1 are substantially equal, the platter or the like is the opening of the washing tub 2. It can be easily put in and out without contacting the edge of the portion 4.

  As described above, according to the present invention, by opening up to approximately half of the front surface side of the upper surface of the main body 1, it is possible to easily set and take out tableware and the like from the tableware basket 3, and improve the setability of the tableware. Can be made.

  Moreover, since the opening part 4 is the structure which open | releases the front surface and upper surface of the main body 1, the door body 5 which covers this opening part 4 becomes long in the up-down direction rather than the conventional dishwasher of a comparable main body dimension. For this reason, in the case of a single door with an upward opening structure, the door becomes an obstacle and the tableware cannot be taken out. In the case of the downward opening configuration, the door is opened from the main body if it is placed on the front, and there is no cooking space on the kitchen counter. It becomes impossible to open.

  However, according to the configuration of the present invention, the door body 5 is constituted by two doors of the upper door body 6 and the lower door body 7, and the flat portion of the opening 4 provided from the front surface to the upper surface of the cleaning tank 2. By providing an engagement portion 18 by providing the door 5 with a split position in 1d, the amount of protrusion of the lower door body 7 to the front of the main body 1 when the opening 4 is opened is reduced. The installation depth dimension in front of the main body 1 can be reduced, and the installation property of the main body can be improved even when a water tap or the like is present in the vicinity of the main body 1.

  Further, the upper door support 23 has a position (point D in FIG. 3) that intersects the arcuate portion 1 c that bulges upward from the main body 1 when the opening operation of the door 5 ends. It is configured to be more rearward. When installing a dishwasher on the sink side of a narrow kitchen, it is installed vertically on the right or left sink side of the kitchen as shown in FIG. 3, rather than on the front where the opening 4 of the washing tub 2 is facing the user. There are many cases where it is done. In the case of this vertical installation, when the door 5 is opened and the tableware is taken in and out, it is carried out obliquely in front of the opening 4, but the upper door support 23 of the present invention is when the upper door 6 is closed. It is formed in a substantially arc shape that bulges upward so as to be accommodated in the cover 37, and when the upper door body 6 is opened, the arc-shaped portion 1c in which the upper door body support portion 23 bulges upward is provided. Since it is displaced rearward from the intersecting position and the upper door support 23 does not obstruct the opening 4, the visibility is not obstructed, and the setability of the tableware can be improved.

  The upper door body 6 is provided with a cover 37 for accommodating the upper door body support portion 23, and a portion protruding from the main body 1 of the upper door body support portion 23 when the door body 5 is closed can be accommodated in the cover 37. Therefore, since the upper door body support portion 23 and the upper door body rotation shaft 34 are not exposed to the outside of the main body, foreign matters such as dust and dust are caught or accumulated on the upper door body rotation shaft 25. The door body 5 can be opened and closed smoothly.

  Further, since the moving shaft 27 and the moving groove 28 are also configured not to be exposed to the outside of the main body by the main body side surface body 38, foreign matters such as dust and dust can be prevented from entering the moving shaft 27 and the moving groove 28.

  Moreover, since the upper door body 6 also rotates in conjunction with the rotation of the lower door body 7, the operability and usability of the door body 5 can be improved.

  The upper door body 6 has an opening 42 that opens laterally from the lower end obliquely rearward to the inner surface of the vicinity of the tip located above when the opening 4 of the cleaning tank 2 is closed, and above the opening 42. A groove 43 having an opening on the inside is provided, and a lid 41 is disposed so as to cover the opening 42 and the groove 43 by opening a part of the lower portion of the opening 42 with a plurality of holes 45, and an upper door body. 6 is attached. And in order to ensure the sealing performance with respect to washing water when attaching the cover body 41 to the upper door body 6, it is set as the structure which apply | coats the adhesive agent 44 to the groove | channel 43 of the upper door body 6, and attaches it. Further, in the fully open state of the door body 5, the tip portion of the upper door body 6 including the opening portion 42 passes through the top portion 17 of the main body 1 and turns downward on the back side, and the state in which the opening portion 4 is closed is: The upper and lower sides are reversed, and the opening 42 is positioned below the upper door body 6.

  Therefore, even when the door body 5 is opened and closed during the cleaning, the opening portion constituted by the upper door body 6 and the lid body 41 from the hole 45 provided with the water droplet 46 flowing through the inner surface of the upper door body 6 in the lid body. 42, the water droplet 46 can be prevented from dripping and flowing down to the sink 60 on the substantially arc-shaped main body, so that the main body 1 and the sink 60 can be kept clean and disposed on the back of the product. Since the water droplet 46 is not attached to the power cord portion (not shown), safety can be improved. Further, since the water droplets 46 accumulated in the opening part 42 are disposed so as to return to the inside of the washing tub 2 from the opening 4 at the front part of the main body 1 when the door body 5 is closed, the water drops 46 are returned to the main body 1 when the door body 6 is opened and closed. The water droplet 46 can be prevented from falling.

  In addition, since a lattice-like exhaust window 40 for exhausting the air in the cleaning tank 2 to the outside of the apparatus is disposed on a part of the front surface facing the outside air of the open portion 42, the inner surface of the exhaust window 40 and the like Water droplets condensed on the inner wall of the opening part 42 can also be collected in the opening part 42 when the door body 5 is opened, and returned to the cleaning tank 2 when the door body 5 is closed. It should be noted that the same action and effect can be obtained with respect to the water droplet 46 flowing along the inner surface of the upper door body 6 regardless of whether the exhaust window 40 is disposed on the front surface of the open portion 42.

  Moreover, since the rib 48 was arrange | positioned in the cover body 41 so that it might become a labyrinth structure in the location facing the groove | channel 43 provided in the upper door body 6 of the cover body 41, the upper door body 6 and cover body in the adhesive agent 44 are provided. The seal area is secured by increasing the adhesion area with 41, and the water flowing into the opening 42 is leaked by the labyrinth configuration regardless of variations in the application of the adhesive 44 (due to workers and automatic machines). Since it can be stored in the open portion 42 without any problems, the quality can be improved.

  Further, when it is possible to take a sufficient space in the groove 43 of the upper door body 6, even when the adhesive 44 is not applied by making the labyrinth structure two layers and three layers, Water droplets can be stored in the open portion 42, and an equivalent effect can be obtained. Thereby, application | coating of the adhesive agent 44 can be abolished and the cost of an installation and material cost can be reduced.

  Also, ribs 47 that allow water droplets 46 to flow into the space between the upper door body 6 and the lid body 41 when the door body 5 is opened extend longer than the lower ends of the other portions at the left and right ends of the horizontally long lid body 41. Therefore, when the door body 5 is opened and closed after the operation is completed (cleaning and rinsing process) or during the operation (during cleaning, etc.), water droplets 46 adhering to the upper door body 6 are formed on the wall of the upper door body 6. The water droplets are received by the ribs 47 provided on the lid body 41, and the received water droplets 46 are constituted by the upper door body 6 and the lid body 41 and flow into the opening portion 42. Because of such a configuration, the flowing water droplets 46 can be efficiently collected in the open portion 42 of the upper door body 6, and the water droplets 46 can be prevented from falling onto the main body 1.

  As described above, the dishwasher of the present invention can easily set and remove tableware and the like from the tableware basket, and allows water droplets flowing through the door body to open and close from the hole in the lid body when the door body is opened and closed. To prevent water droplets from dripping onto the generally arc-shaped body, and since the water droplets do not reach the sink through the body, the main body and the sink are kept clean and the power cord arranged on the back of the product It is useful as a dishwasher that has improved the safety by eliminating water droplets on the part.
