Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dishwasher that cleans tableware by spraying a cleaning liquid.

Conventionally, in this type of dishwasher, as shown in FIG. 3, a dishwashing tank 1 houses dishwashing baskets 3 and 4 containing dishes 2, and a washing liquid is placed at the bottom of the dishwashing tub 1. 5 is stored, and this is sent to the cleaning pump 6.
The cleaning liquid 5 is sent to the rotary arm nozzles 10 and 11 through the recessed food waste filter 8 that covers the bottom recess 7 of the dishwashing tank and the water intake port 9, and is sprayed onto the dishes 2, thereby washing the dishes 2. The cleaning liquid or rinsing liquid after cleaning is discharged to the outside of the main body 14 through the drain port 12 by the drain pump 13. In this draining process, in the conventional dishwasher, as shown in FIG. 4, the drain pump 13 operates when the washing pump 6 finishes operating (washing or rinsing) to drain the washing liquid or rinsing liquid. Problems to be Solved by the Invention When such a method is carried out, while the washing pump 6 is operating, leftover food and dirt that have fallen from dishes etc. are drawn in by the suction force of the washing pump 6, and are filtered through the recessed food waste filter. 8
However, as soon as the washing pump 6 finishes operating, the leftover food and dirt, which has a specific gravity lighter than that of water, floats up and spreads over the entire bottom of the dishwashing tank 1 where the washing liquid 5 is collected. Put it away. When the drainage process starts in this state and the drainage pump 13 is operated,
Since the water level gradually decreases, the leftover food remains attached to the bottom of the dishwashing tank 1. No matter how many times you repeat the rinsing process, this kind of situation cannot be fundamentally resolved, and even after all the processes of the dishwasher are completed, some leftover food remains scattered on the bottom of the dishwashing tank 1. Therefore, it is not enough just to take out the leftover filter 8 and clean it, but the post-processing is troublesome and may cause the generation of bad odors.

The present invention is a dishwasher that solves these conventional problems and aims to simplify the post-processing of leftovers and the like.

Means for Solving the Problems In order to achieve the above object, the dishwasher of the present invention includes a dishwashing tank, a washing pump that circulates the washing liquid stored at the bottom of the dishwashing tank, and a washing liquid in the dishwashing tank. A rotating arm nozzle that sprays
a drain pump for discharging cleaning liquid etc. to the outside of the main body, a recess is formed in the bottom of the dishwashing tank, and the bottom of the dishwashing tank is inclined so that the cleaning liquid etc. flows toward the recess; The concave portion has a drain port communicating with the drain pump, a water suction port communicating with the washing pump, and a removable concave debris filter that covers the concave portion of the bottom surface of the dishwashing tank, during draining operation of the washing liquid or rinsing liquid. The cleaning pump is configured to operate intermittently or continuously.

Function The dishwasher of the present invention has a washing pump, a drain pump, and a waste filter, and operates the washing pump during draining operation to circulate the washing liquid.
The leftover food etc. are surely collected in the leftover food filter, and the post-processing of the leftover food is simplified.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In the configuration of the conventional dishwasher shown in FIG. 3, as shown in FIG. 13), the cleaning pump 6 is operated continuously (solid line) or intermittently (broken line).
It is something.

Next, this operation will be explained. When the cleaning pump 6 is operated in the draining process as explained in FIG. 1, on the one hand, from the drain port 12 as shown in FIG.
The cleaning liquid and the rinsing liquid are gradually discharged by the drain pump 13, and on the other hand, by the cleaning pump 6, from the water inlet 9 to the cleaning pump 6, the rotating arm nozzle 10,
11. Inside the dishwashing tank 1 and concave leftover filter 8;
The cleaning liquid 5 or the rinsing liquid circulates through the recess 7 on the bottom surface of the dishwashing tank. At this time, the water level of the cleaning liquid 5 accumulated at the bottom of the dishwashing tank 1 gradually lowers as it drains, and the floating leftover food a adheres to the bottom of the tank, but the cleaning pump 6 continues to operate. Therefore, when the adhering leftover food a is washed away by the water flow and suction power, the washed away leftover food is tilted so that the bottom surface of the dishwashing tank faces the recess 7 and the washing liquid etc. flows into it. Therefore, it flows smoothly into the recess 7, and finally all of it flows into the recess of the waste filter 8. Therefore, after all the cycles of the dishwasher are completed, the removable recessed food waste filter 8 is simply taken out and cleaned, making post-processing extremely easy and sanitary. Further, the effect of running the cleaning pump intermittently is that if it is operated continuously, the large suction force of the cleaning pump will affect the drainage capacity of the drainage pump, which will lengthen the drainage time. To solve this problem, the cleaning pump is operated intermittently.

Effects of the Invention As is clear from the above embodiments, the dishwasher of the present invention operates the drain pump and the washing pump in parallel, especially in the draining process, and the washing effect of water flow in the dishwashing tank caused by the operation of the washing pump causes floating,
Dispersed leftovers can be collected in one place, improving post-processing of leftovers and hygiene.
