Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a dishwasher for washing and drying dishes.

Prior Art As shown in FIG. 3, a conventional dishwasher has a washing tank 2 installed inside a main body 1 of the dishwasher. 3
A cleaning pump circulates the cleaning tank in the cleaning tank 2, and is rotationally driven by a cleaning pump motor 4.
5 is a residue filter installed at the bottom of the cleaning tank 2;
Washing water sucked in from the leftover filter 5 is pressurized by a washing pump 3 and is ejected from a nozzle 6 to wash dishes 8 placed in a basket 7. The car 7 has a structure in which wheels 9 fixed to the car itself move on a wheel running surface 10 on the washing tank side formed on the inner wall of the washing tank 2. Reference numeral 11 denotes a door that can be opened and closed at the front of the washing tank 2 to take in and take out the tableware 8;
A wheel running surface 12 on the door side of the car 7 is formed on the surface of the door 11 on the cleaning tank 2 side.

The basket 7 moves back and forth between the wheel running surface 10 on the washing tank side and the wheel running surface on the door side.
Take in and out. Also, on the back of door 11, there is a fourth
As shown in the figure, wheel running guide ribs 13 are provided to regulate the position of the wheels 9 of the car 7 in the left-right direction. On the other hand, the inner wall of the cleaning tank 2 has a wheel running surface 1.
0 is provided, and its side wall portion 15 regulates the position when the basket 7 is stored in the cleaning tank 2.

Problems to be Solved by the Invention According to the conventional configuration, when the car 7 is pulled forward, the wheels 9 may get caught on the guide rib end 14 formed on the back surface of the door 11, making smooth movement impossible. do. This is the outer width of the wheel 9 and the inner width of the wheel running surface (the back side of the cleaning tank 2 and door 11).
On the other hand, when the back of the door 11 is made of synthetic resin, the width of the wheel running surface 12 expands and contracts when the washing water temperature changes and when it is cold or hot, so when the car is pulled out, 7 is slanted,
This is because the wheel 9 comes into contact with the guide rib end portion 14.

If there is no smooth movement when moving the basket 7 back and forth, there has been a problem that the tableware set in the basket 7 may break or be partially chipped.

This invention solves these problems,
The purpose is to make the basket move smoothly in the front and back direction, improve the feeling of operation, and prevent tableware from being damaged.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a washing tank having an opening on the front side, and a wheel on the side of the washing tank on which a wheel of a dish basket is placed inside the washing tank. The door is provided with a running surface and a door that covers the washing tank opening, and the door is configured to open approximately 90 degrees forward with its lower part as the center of rotation. In addition, guide ribs for the dish basket are provided on both outside sides of the back of the door, extending along the inner wall of the washing tank. The outer surface has a superimposed surface that overlaps with the outer surface of the wheel.

Effect In the above configuration, when the car is placed on the wheel running surface of the cleaning tank, the wheels are always overlapped with the wheel running guide ribs on the back of the door, so when the car is moved back and forth, the wheels on the back of the door cannot be moved. It is possible to prevent it from getting caught on the end of the travel guide rib.

Embodiment Hereinafter, an embodiment of the dishwasher of the present invention will be described based on the drawings.

In Figures 1 and 2, 15 is a cleaning tank, 16
is a washing tank side wheel running surface formed on the inner wall of the washing tank, and the wheels 18 of the tableware basket 17 are placed on this surface. Reference numeral 19 denotes a door provided on the front surface of the cleaning tank 15 so as to be openable and closable, and a door-side wheel running surface 20 is formed on the back surface, and a guide rib 21 is provided protruding from the outside thereof.
Reference numeral 22 denotes a portion where the guide rib 21 overlaps with the wheel 18, which is formed by extending the guide rib 21 toward the back of the cleaning tank 2. This polymerization part 2
2 is formed in a substantially arc shape with respect to the door rotation center 23 so that it always overlaps the outer surface of the wheel 18 regardless of whether the door 19 is opened or closed.

Therefore, since the wheels 18 of the car 17 are always superimposed on the inner surface of the guide rib 21 of the door 19 while being placed on the wheel running surface 16 in the cleaning tank 2, the wheels 18 of the car 17 are not moved forward or backward. Guide rib 2 for loading and unloading
It will not hit the end of 1.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the outer surface of the car wheel and the wheel running guide rib on the back surface of the door are always overlapped, so that when the car is moved in and out of the front and back, The wheels do not get caught on the ends of the guide ribs, allowing smooth operation of loading and unloading the car.
It is possible to prevent tableware from being damaged.
