Description

[Detailed description of the invention] [Purpose of the invention] The invention relates to an assembly structure for a washing pump and a drain pump in a dishwasher used in general households, and its purpose is to improve productivity. The object of the present invention is to provide a dishwasher having a rational assembly structure.

The assembly structure of a washing pump and a drain pump in a conventional dishwasher will be explained with reference to FIG. 1 is the main body of the dishwasher, 2 is a washing tank, 3 and 4 are dish baskets that accommodate dishes to be washed (not shown);
Reference numerals 5 and 6 are injection nozzles that spray cleaning water, and 7 is an opening/closing door provided at the front opening of the cleaning tank 2 so as to be openable and closable. Reference numeral 8 denotes a cleaning pump driven by a motor 9, and a cleaning water reservoir chamber 10 formed at the bottom of the cleaning tank 2.
Cleaning water sucked from the jet nozzles 5 and 6 is supplied to the jet nozzles 5 and 6. Reference numeral 11 denotes a drainage pump which sucks the washing water from the washing water reservoir chamber 10 and discharges it after washing and rinsing are completed. 12 is a filter.

By the way, in the above structure, the cleaning pump 8
The housing 13 of the housing 13 is directly connected to the wash water reservoir chamber 10, while the drain pump 11 is connected to the wash water reservoir chamber 10 by a hose 14. In this way, the connection using the hose 14 requires a band or adhesive to prevent water leakage at the connection part, and also requires a large number of parts such as metal fittings to separately fix the drain pump 11, and is difficult to assemble. It takes a lot of time. The present invention aims to solve this problem and provide a structure that can improve productivity.

[Structure of the idea]

The dishwasher of the present invention is provided with a mortar type filter, which forms a fine filter on the surrounding side surface and a coarse filter on the bottom surface, at the bottom of a washing tank having a washing water injection nozzle, and is provided below the coarse filter. A first wash water reservoir is directly connected to the housing of the drainage pump to serve as a wash water suction chamber of the drain pump, and a second wash water reservoir formed around the fine filter is directly connected to the housing of the wash pump. and a cleaning water suction chamber for supplying the cleaning water to the injection nozzle.

An embodiment of the invention will be described with reference to FIG. 1
Reference numeral 5 denotes a filter attached to an opening 16 provided at the bottom of the cleaning tank 2, and has a mortar-like shape, with a narrow filter 15a formed on the surrounding side surfaces and a coarse filter 15b formed on the bottom surface. 17 is filter 1
A first wash water reservoir chamber provided below the drain pump 5 is directly connected to the housing 19 of the drain pump 18 and becomes a wash water suction chamber of the drain pump 18. Filter 1
5 forms a second cleaning water reservoir chamber 20, which is directly connected to the housing 22 of the cleaning pump 21 and becomes a suction chamber for cleaning water supplied to the injection nozzles 5 and 6. 23 is an impeller of the drain pump 18, 24 is a discharge port, 25 is a motor, and 26 is a cooling fan.
27 is a discharge port of the cleaning pump 21.

[Effect of idea]

As described above, in the dishwasher of the present invention, the area around the filter 15 provided at the bottom of the cleaning tank 2 forms the cleaning water suction chamber 20 of the cleaning pump 21 having the fine filter 15a, and the injection nozzles 5, 6 is supplied with cleaning water with little waste. Further, since a washing water reservoir chamber 17 having a coarse filter 15b is formed below the filter 15, large dirt is discharged by a drainage pump 18. And the housings 19 and 22 of the drain pump 18 and the cleaning pump 21
is integrally connected to the cleaning water reservoir chambers 17 and 20, and the drain pump 18 and the cleaning pump 21 are configured to be driven by independent motors 25 and 9, respectively. In addition to being able to solve the above-mentioned problems with the structure, both pumps can be mounted in the best configuration, preventing water leakage and saving space.
