The opening 4 is opened by rotating in the direction of arrow B. Further, when the opening 4 is opened, the upper door 6 moves to the rear of the main body about the upper door rotation shaft 25, but the upper door support portion 23 is behind the upper end 39 of the opening 4 at the end of the movement. At this point, the stopper portion 35 comes into contact with the stopper receiving portion 36 and the upper door 6 and the lower door 7 are stopped and do not move any further.

  Next, the operation and action of the dishwasher 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 (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 a conventional dishwasher in the kitchen, there is no problem if the controller is installed higher than the height of the main body of the dishwasher, but if the controller is installed slightly lower, the display provided on the controller In order to ensure the visibility of the parts and the operability of the switches, the dishwasher must be installed away from the wall surface, which impairs the workability in the kitchen. And when the controller was installed lower, the dishwasher could not 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 without any problems. Further, since the user can visually recognize the controller from above through the upper part of 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, in the kitchen which has already installed controllers, such as a bathtub and a water heater, the visibility and operativity of a controller can be ensured and installation property can be improved.

  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 to thereby clean the washing tank. 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.

  In addition, in the 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 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 attached to the surface of the object to be washed is low, but according to the present embodiment, the amount of washing water on 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.

  In addition, the upper end 39 of the opening 4 provided on the upper surface of the cleaning tank 2 is formed so as to be located in the vicinity of the top 17 of the arcuate part 1c bulging upward, so that the upper area of the cleaning tank 2 is increased. About half of the aperture can be opened. 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 such that the center of gravity of the dishes and the center of the arcuate portion 1c bulging upward from the front surface 1a of the main body 1 are substantially equal, It can be easily put in and out without contacting the edge of the opening 4.

  As described above, according to the present embodiment, by setting the opening 4 to approximately half of the front surface side of the upper surface of the cleaning tank 2, it is easy to set and remove the article to be cleaned 19 from the tableware basket 3. It is possible to improve the setability of the article 19 to be cleaned.

  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, when it is set as the open top structure with the single door like the past, a door body becomes obstructive and cannot take out a to-be-cleaned object. In addition, in the case of a single door with a downward opening structure, if the door is placed in front, the door is opened from the main body, and there is no cooking space on the kitchen counter. However, according to the present embodiment, the door body 5 is composed of the two doors of the upper door 6 and the lower door 7, and the door cannot be completely opened. The lower door when the opening 4 is opened by providing the dividing portion of the door body 5 at the position of the flat surface portion 1d of the opening 4 provided from the front surface to the upper surface of the tank 2 to constitute the engaging portion 18. 7 can reduce the amount of projection to the front of the main body 1 to reduce the installation depth dimension in front of the main body 1 when the main body 1 is installed, and the main body 1 can be installed even when a water tap or the like is present in the vicinity of the main body 1. Can be improved.

  Further, the upper door support portion 23 is located behind the upper end 39 of the opening 4 at a position (point D) that intersects the arcuate portion 1c that bulges upward from the main body 1 when the opening operation of the door body 5 is completed. It is comprised so that it may become. When installing a dishwasher on the sink side of a narrow kitchen, it is better to install it 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 faces the user. Many. In the case of this vertical installation, when the door body 5 is opened and the object to be cleaned 19 is taken in and out, it is carried out obliquely in front of the opening 4, but the upper door support 23 in the present embodiment closes the upper door 6. When the upper door 6 is opened, the arcuate portion 1c in which the upper door support portion 23 bulges upward is formed so as to be accommodated in the cover 37. Therefore, the upper door support portion 23 does not obstruct the opening 4, so that the field of view is not obstructed and the setability of the cleaning object 19 can be improved.

  Moreover, since the cover 37 which accommodates the upper door support part 23 in the upper door 6 is provided, and the upper door support part 23 can be accommodated in the cover 37 when the door body 5 is closed, the upper door support part 23 and The upper door rotation shaft 37 is not exposed to the outside of the main body 1, and foreign matters such as dust and dirt can be prevented from being caught or accumulated on the upper door rotation shaft 25, and the door body 5 can be opened and closed smoothly. be able to.

  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 1 by the main body side body 38, it is possible to prevent foreign matters such as dust and dirt from entering the moving shaft 27 and the moving groove 28. .

  Further, 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.

  Moreover, in this Embodiment, as shown in FIG. 5, the water receiving rib 6a which protrudes inward is provided in the rear end of the upper door 6. As shown in FIG. Thereby, when the door body 5 is opened during the cleaning, the water receiving rib 6a receives the water droplet 41 flowing through the door body 5, so that the water droplet 41 is prevented from dripping on the substantially arc-shaped main body 1. Since the water droplet 41 does not reach the sink 50 through the main body 1, the main body 1 and the sink 50 can always be kept clean, and the power cord (not shown) attached to the back of the dishwasher Water droplets do not adhere and safety can be improved. The water receiving rib 6a is formed to return the accumulated water droplet 41 from the opening 4 to the washing tub 2 when the upper door 6 is closed.

  In the present embodiment, as shown in FIG. 6, the upper door 6 is provided with an exhaust window 42 for discharging steam generated in the cleaning tank 2 to the outside during the drying process of drying the object 19 to be cleaned. A lid 43 that covers an opening (not shown) of the exhaust window 42 is accommodated, and a water receiving rib 43a that receives water droplets is disposed at the top end of the lid 43. This is the same as Form 1.

  The operation and action of the dishwasher with the above configuration will be described.

  The operation of the upper door 6 is the same as that in the first embodiment. By configuring the exhaust window 42 in the upper door 6, the upper portion of the main body 1 can be made smaller, the opening 4 can be enlarged, and the object 19 to be cleaned can be easily taken in and out, Since the upper door 6 and the lid 43 are configured separately, the water receiving rib 43a can be formed on the lid 43 according to the opening / closing angle without being limited by the mold configuration, so that more water droplets can be received. It is possible to eliminate the possibility of water droplets adhering to the mounting portion of the power cord disposed on the back portion of the product, and to further improve the safety.

  As described above, the dishwasher according to the present invention makes it easy to set and remove an object to be cleaned from the tableware basket, and can greatly improve the setability of the object to be cleaned. Prevents water droplets from dripping onto the arc-shaped body and prevents the water droplets from reaching the sink through the body, keeping the body and sink clean, and to the power cord attachment on the back of the product It can be applied to household and commercial dishwashers and washing machines.
