DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher for washing dishes.

[0002]

2. Description of the Related Art In a conventional dishwasher, cleaning water pumped by a cleaning pump is jetted from a cleaning nozzle located in a space above a cleaning tank via a water pipe (outside) and a water pipe (inside). The tableware placed in the tableware basket was washed. In such a dishwasher, the path from the washing pump to the washing nozzle has been sealed by pressing the respective surfaces with an O-ring or a flat packing interposed therebetween. Therefore, each joining portion requires a fastening member, and also requires accurate mutual positioning.

[0003]

In a conventional dishwasher, since there are many joints as described above in a path from a washing pump to a washing nozzle, mutual positioning is required to prevent water leakage. It was important that not only the dimensional accuracy of each part in that aspect was required, but also the latest attention was required for assembly. As a result, not only does the cost of the parts of the seal part increase, but also the assembly work becomes complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a dishwasher which can surely prevent water leakage from a joint in a path from a washing pump of a dishwasher to a washing nozzle and has a simple assembling work. .

By sealing the joint in the plane direction, the joint at which water pressure is applied can be reliably sealed, and the reliability against water leakage is improved.

According to a third aspect of the present invention, there is provided a washing tank for accommodating a dish basket on which tableware is placed, a washing pump for pressure-feeding washing water supplied into the washing tank, and a washing pump positioned in the washing tank for supplying washing water. A cleaning nozzle for spraying, a water pipe (inside) for supplying cleaning water to the cleaning nozzle, and a water pipe (outside) located outside the wall surface of the cleaning tank and communicating from the cleaning pump to the water pipe (inside). In the dishwasher provided with, the connecting direction of the joints with the members joined to both ends of the water pipe (outside) is one in the horizontal direction and one in the vertical direction, and each joint is sealed in the radial direction. By doing so, the sealing can be reliably performed without separately providing a fixing means at the joint.

According to a fourth aspect of the present invention, the joint between the water pipe (outside) and the water pipe (inside) is radially sealed, and the joint between the water pipe (outside) or the water pipe (inside) and the cleaning tank is sealed. By sealing in the plane direction, in addition to the effect of claim 1, furthermore, it is possible to reliably seal the joint where the water pressure is applied.
The reliability against water leakage is improved.

According to a fifth aspect of the present invention, the connecting directions of the joints with the members joined to both ends of the water pipe (outside) are one in a horizontal direction and one in a vertical direction, and each joint is sealed in a radial direction. By doing so, in addition to the effects of claims 1, 2, and 4,

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. This dishwasher has an exterior 9 as shown in FIG.
The washing tank 1 is built in the inside of the container, and two doors 10 are provided on the front surface.
And the lower tableware basket 2b are freely installed and removed, and two upper cleaning nozzles 3 that rotate in a plane between the upper tableware basket 2a and the lower tableware basket 2b are arranged on the left and right sides, and the lower part rotates in a plane below the lower tableware basket 2b. Two cleaning nozzles 4 are arranged on the left and right. FIG.
As shown in FIG. 1, a water pipe 7 is provided as a water pipe (outside) between a wall surface of the cleaning tank 1 and the exterior 9, and an upper cleaning nozzle 3 is provided above a rear wall of the cleaning tank 1. An upper cleaning nozzle bracket 5 is provided as a water pipe (inside) for supplying cleaning water to the cleaning tank 3 and holding the upper cleaning nozzle 3.
A lower cleaning nozzle bracket 6 is provided below a water pipe 7 that supplies cleaning water to the lower cleaning nozzle 4 and holds the lower cleaning nozzle 4. A cleaning pump 8 is provided below the lower cleaning nozzle bracket 6, and the lower cleaning nozzle bracket 6 is provided.
The cleaning water is supplied to the upper cleaning nozzle bracket 5 via a water guide pipe 7 which is located on the back of the cleaning tank 1 and communicates from the cleaning pump 8 to the upper cleaning nozzle bracket 5 via the lower cleaning nozzle bracket 6. Pumping wash water to

The upper joint portion 11 between the upper cleaning nozzle bracket 5 and the water pipe 7 is located at the penetrating portion of the cleaning tank 1, and the cleaning water pumped from the cleaning pump 8 is supplied as shown in FIG. At the joint between the upper cleaning nozzle bracket 5 and the water pipe 7, a seal is made in the radial direction using an O-ring 13,
The joint between the cleaning tank 1 and the water pipe 7 has a structure in which a flat packing 15 is used to seal in the surface direction. Furthermore, the joint 11 between the water pipe 7 and the lower cleaning nozzle bracket 6 is
As shown in FIG. 4, a structure is adopted in which the O-ring 14 is used to seal in the radial direction.

Next, an assembling procedure will be described. The upper cleaning nozzle bracket 5 has a rear convex portion inserted into the penetrating portion of the cleaning tank 1 via a flat packing 15 and fixed by fixing means separately provided on the side surface of the cleaning tank 1. Lower cleaning nozzle bracket 6
The cleaning pump is fixed by a fixing means separately provided on the back side of the bottom of the cleaning tank 1. After inserting the lower end concave portion of the water guide pipe 7 into the upper convex portion of the lower cleaning nozzle bracket 6 together with the O-ring 14, the upper concave portion is inserted together with the O-ring into the rear convex portion of the upper cleaning nozzle bracket 5. 1 is fixed to the back of the device 1 with fixing screws 16.

It is possible to simultaneously fix the upper cleaning nozzle bracket 5 and the water guide pipe 7 to the cleaning tank 1 by one fastening, and the assembly work is one time as compared with the case where the joint and the penetrating part are separately provided. And the number of members required for fixing can be reduced. Furthermore, since the upper joint portion 11 and the lower joint portion 12 are sealed in the radial direction, they can be reliably sealed without being affected by the deviation in the surface direction at the joint portion of the members.

In this embodiment, the joint between the upper cleaning nozzle bracket 5 and the water guide pipe 7 is provided on the back surface of the cleaning tank 1. However, the same effect can be obtained on other wall surfaces.
