Hereinafter, described in detail by the accompanying drawings a preferred embodiment for achieving the above object is as follows.

As shown in FIG. 1 to FIG. 7, a washing water tank 11 and a rinsing water tank 12 are respectively installed below the case 10 of the dishwasher 1, and the tanks 11 and 12 are respectively provided. The washing water and the rinsing water, respectively stored in the pump, can be transferred through the respective supply pipes 13 by pumps.

The washing water and the rinsing water transferred through the supply pipes 13 are sequentially sprayed onto the dishes 15a placed on the rack 15 through the nozzles 14a of the upper and lower injection pipes 14 rotatably mounted. It is configured to be.

The bent vertical frame 20 is mounted at both rear sides of the case 10, and the guide rails 41 are mounted at both inner rear sides of the cover 40, and the rollers 21 are mounted at the vertical frame 20. ) Are mounted and slide coupled to the guide rail 41.

Therefore, as the guide rails 41 on both sides are coupled to the rollers 21 of the vertical frame 20 and lifted while the guide rails 41 are stably supported, the cover 40 is moved from the upper portion of the case 10. It is configured to open and close while lifting.

Of course, the dishwasher 1 having the above-described configuration is a known art. However, the most important feature of the present invention is that the spring 34a and a linkage device are installed inside the cover 40 of the dishwasher 1, which not only maintains the appearance of the overall dishwasher but also the dishwasher is placed. Losing land is to take up less space.

That is, vertical frames 20 are mounted on both rear sides of the case 10, and guide pieces 22 are mounted on both sides of the vertical frame 20, respectively, and inside the guide pieces 22. The operation plate 30 is coupled to the shaft 31 and rotatably mounted. The shaft 31 is coupled to the guide piece 22 through the lower center of the operating plate 30.

The operating rods 32 are fixed to the two operating plates 30, respectively, and a link piece 33 is coupled to the tip of the operating rod 32 by a pin 32a. The front ends of both side link pieces 33 are fixed to pins 33a on both sides of the cover 40, respectively.

Guide rods 34 are mounted between the operation plates 30 on both sides, and the guide rods 34 are fixed by bolts passing through the upper rear of the operation plates 30. The guide rod 34 is mounted at a rear diagonal position in the upper diagonal direction of the shaft 31 penetrating the operating plate 30.

Springs 34a are mounted on both sides of the guide rod 34, respectively, and support pieces 42 are fixed on both lower sides of the rear plate 40a mounted on both vertical frames 20, respectively. Shaft bolts 43 are screwed to the support pieces 42. Lower portions of the two side springs 34a are fixed to an upper portion of the axial bolt 43 screwed to both of the support pieces 42.

Adjusting nuts 43a are screwed to the upper and lower portions of the shaft bolts 43 and are positioned with the support pieces 42 interposed therebetween, and the shaft bolts 43 are supported by rotating the nuts 43a to adjust their positions. Raised from the piece 42 is configured to appropriately adjust the tension of the spring (34a).

The front handles of the cover 40 are respectively equipped with a handle 50 continuously bent in one direction, and both sides of the handle 50 are in close contact with the front surface and one side of the cover 40 and fastened therethrough. It is firmly fixed by the bolt 51, and when the bolt 51 is removed, the handle 50 is also separated.

Therefore, when the dishwasher 1 is installed in the corner, it can be installed as close as possible to the corner with the handle 50 on one side removed, thereby minimizing the installation space of the dishwasher 1 and efficiently freeing space. It can be used to advantage. Of course, at this time, the cover 40 can be opened and closed by using the handle 50 of the other corner which is not separated.

In addition, the ceiling of the cover 40 is projected to form a gentle inclined surface in the center, even when water is scattered on the ceiling when the dish is being washed, since it is quickly dropped and processed through the inclined surface, after the washing of the dishes is completed. The washing water falls from the ceiling to the dishes, thereby preventing the contamination of the dishes.

In the present invention having the above-described configuration, as shown in FIG. 5A, while the washing operation is in progress, the link piece 33 fixed to the cover 40 moves the operating rod 32 downward while the cover 40 is closed. When the operation plate 30 is inclined forward and the operation plate 30 is inclined forward, the guide rod 34 is positioned directly above the shaft 31 passing through the operation plate 30. As the spring 34a mounted on the guide rod 34 is vertical in the shaft 31 and pulls the operating plate 30 down, the pulling force of the spring 34a is weak on the operating plate 30. The cover 40 having a considerable weight can be stably held closed by its own weight.

Then, the cleaning operation is completed, while holding the handles on both sides to lift the cover 40 up, as shown in Figure 5b, while the link piece 33 inclined forward to lift the operating rod 32 upwards As the operating plate 30 is rotated upwardly about the shaft 31, the guide rod 34 is moved to the rear of the shaft 31 to be out of the vertical state, and thus the pulling force of the spring 34a is the operating plate 30. The operating plate 30 is pulled down by the force of the spring 34a, and the pulling force is transmitted to the cover 40 through the operating rod 32 and the link piece 33 to lift the cover 40. Since the heavy cover 40 is easily lifted even when a relatively light force is applied, the cover 40 can be opened very easily.

In addition, when the cover 40 is continuously raised and fully opened, the guide rod 34 is positioned at the rear of the shaft 31 so that the pulling force of the spring 34a is pulled very strongly at right angles to the shaft 31. The open cover 40 is fixed by the force of the spring (34a) to maintain a stable open state.

On the other hand, the inclined surface (30a) is formed on the lower rear of the operating plate 30, the stopper (22a) of the elastic material is fixed to the lower bent piece (22b) of the guide piece 22 to lift the cover 40 When fully opened, the inclined surface 30a of the operating plate 30 is in close contact with the stopper 22a of rubber material, and the operating plate 30 is elastically supported so that the cover 40 is no longer opened.

In the above described and illustrated with respect to the preferred embodiment of the present invention, the present invention is not limited to the above-described embodiment, it is common in the field to which the present invention belongs without departing from the spirit of the present invention claimed in the claims. Various modifications can be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.

The present invention as described above, the operation plate 30, the operating rods 32, respectively mounted on both vertical frames 20 are received by the pulling force of the spring 34a, the cover 40 is very simple It can be opened and closed, while maintaining the open and closed state of the cover 40 at the same time, the spring 34a and various link devices are installed on both sides of the cover 40 so that they are hidden from view from the outside. Not only can the appearance of 1) be kept beautiful, but since there are no devices protruding from the outside of the dishwasher 1, the dishwasher 1 can be installed as close to the wall or corner as possible, so that the space occupied by the dishwasher It is minimized, so that the remaining free space can be effectively used, which can maximize the external competitiveness of the dishwasher.
