  Next, the operation of the dishwasher in the above embodiment will be described.

  When installing the dishwasher, there are cases where the front of the dishwasher is placed forward or along the side wall (not shown) of the kitchen. In recent kitchens, a controller (not shown) 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 present embodiment, since 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, even when the controller is installed low, it contacts 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 this Embodiment, the visibility and operability of a controller can be ensured and installation property can be improved also in the kitchen which has already installed controllers, such as a bathtub and a water heater.

  Further, the upper shape of the main body 1 and the upper shape of the upper door 6 are formed in a substantially arc shape that bulges upward, and the upper door 6 is moved along the arc-shaped portion 1c of the upper portion of the main body 1 so as to be washed. 2 is configured to open and close the opening 4 provided from the front to the top, 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.

  In addition, in a conventional dishwasher, the shape seen from the side of the main body from the back to the top of the washing tub is substantially perpendicular, so that the washing water that flows from the back to the top of the washing tub at the time of washing is on the top. Since it is difficult to reach and there is little washing water that pours into the tableware from the upper surface, the washing performance of dirt adhering to the surface of the object to be washed 19 is low, but according to this embodiment, the amount of washing water to the upper surface of the washing tank 2 increases. Therefore, the amount of cleaning water that pours onto the object to be cleaned 19 from the upper surface increases, and the dirt adhering to the surface of the object to be cleaned 19 can be reliably washed away.

  Further, the opening 4 is formed so as to include the front surface 1a of the main body 1 and the arc-shaped portion 1c provided so as to bulge outward from the front surface 1a to the upper surface. Setting and taking-out are facilitated, the setability of the object to be cleaned 19 is improved, and installation in a kitchen in which a controller such as a bathtub or a water heater is already installed is facilitated.

Further, the upper end portion 39 of the opening 4 provided on the upper surface of the main body 1 is formed so as to be positioned in the vicinity of the top portion 17 of the arc-shaped portion 1c that bulges upward. It can be set as the structure which opens half. Therefore, the field of view up to the back of the upper basket 9 is widened, and the object to be cleaned 19 can be easily put in and out. In particular, since the tableware basket 3 is configured so that the distance from the front surface of the main body 1 at the center of the arcuate portion 1c that bulges upward is the center of gravity of the dishes, the platter or the like is the opening of the washing tank 2 It can be easily put in and out without contacting the edge of 4.

  As described above, according to the present embodiment, by setting the opening 4 to approximately half of the front side of the upper surface of the main body 1, it is possible to easily set and remove the article 19 to be cleaned from the tableware basket 3. The setability of the article 19 to be cleaned can be improved.

  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 longer in the up-down direction than the conventional dishwasher of a comparable main body dimension. For this reason, in the case of a single door body with an open top structure, the door body becomes in the way and the tableware cannot be taken out. Also, in the case of a single door structure with a downward opening, if the door is placed in front, the door will be opened from the main body, and there will be no cooking space on the kitchen counter. Will not be able to open the door completely.

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

  Further, the position (point D) at which the upper door support portion 23 intersects the arc-shaped portion 1 c that bulges upward from the main body 1 at the end of the opening operation of the door body 5 is behind the upper end portion 39 of the opening 4. It is configured as follows. When installing a dishwasher on the sink side of a narrow kitchen, it is more often installed vertically on the right or left sink side of the kitchen than on the front side where the opening 4 of the main body 1 is facing the user. . In the case of this vertical installation, when the door body 5 is opened and the object to be cleaned 19 such as tableware is taken in and out, the opening is performed obliquely in front of the opening 4, but the upper door support 23 in the present embodiment is the upper door. 6 is formed in a substantially arc shape that bulges upward so as to be accommodated in the cover 37 when the lid 6 is closed, and the upper door support portion 23 bulges upward when the upper door 6 is opened. It is displaced rearward from the position intersecting the arcuate portion 1c, and the upper door support portion 23 does not obstruct the opening portion 4, so that the field of view is not obstructed and the setability of the cleaning object 19 can be improved. it can.

  Further, since the upper door 6 is provided with a cover 37 for accommodating the upper door support portion 23 and the door body 5 is closed, the upper door support portion 23 is accommodated in the cover 37. The moving shaft 25 is not exposed to the outside of the main body 1, and foreign matter such as dust and dirt can be prevented from being caught or accumulated on the upper door rotating shaft 25, and the door body 5 can be opened and closed smoothly. it can.

  Further, the moving shaft 27 and the moving groove 28 are also configured not to be exposed to the outside of the main body 1 by the main body side body 38, so that foreign matters such as dust and dust are prevented from adhering to the moving shaft 27 and entering the moving groove 28. be able to.

  In addition, since the upper door 6 is also rotated in conjunction with the rotation of the lower door 7, the operability and usability of the door body 5 can be improved.

Further, in the present embodiment, as shown in FIG. 5, a water receiving body 40 is attached to the tip of the upper door 6 by claw fitting, pinching, adhesion, etc. When the door 5 is opened and closed, the water droplets 42 adhering to the inner wall of the upper door 6 are scattered from the upper door 6 toward the back of the main body 1 due to the impact when the upper door 6 stops in the fully open state. The splashed water droplets 42 are received by the water receiver 40. As a result, it is possible to prevent water droplets 42 from adhering to the back wall or flying to the outlet portion on the back surface of the main body 1, so that the area around the sink 50 can be kept clean at all times, and there is a risk of electric leakage, etc. Can be eliminated and safety can be improved. Moreover, the effect which prevents the water droplet 42 adhering to the door body 5 from scattering becomes the largest by arranging the water receiver 40 on the upper surface from the portion covering the opening 4.

  In the above configuration, when it is desired to reduce the gap 41 between the upper surfaces of the upper door 6 and the main body 1, the water receiving body 40 is made of a soft material so that the door body 5 can be brought into contact with the main body 1 by the opening / closing operation. The appearance of the exterior can be improved without affecting the opening / closing operation of the door body 5.

  In addition, if the water receiving body 40 is formed of a hard material and the gap 41 that does not interfere with the upper door 6 and the main body 1 is designed by opening and closing operation, the upper and lowering operations of the door body 5 are not affected. A hand can be put in the gap 41 between the door 6 and the main body 1, and the tip of the upper door 6 can be forcibly pulled to prevent an unsafe mode, thereby improving safety.
