A water receiver 40 is provided.

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 if 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. It can be set as the structure which opens substantially half. 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 an 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.

  Moreover, since the water receiving part 40 is provided in the back part of the main body 1, even if the water droplet 41 is dripped on the outer surface of the substantially arc-shaped main body 1 mainly from the inner surface of the upper door body 6 when the door body 5 is opened and closed. 1 is received by the water receiving portion 40 on the back surface portion, so that the water droplet 41 does not hang down on the sink 60 and can be kept clean, and a power cord portion (not shown) disposed on the back surface portion of the product. ) Can be prevented from adhering to the water droplets 41 and safety can be improved.
