BACKGROUND ART In general, a dishwasher is a device that sprays washing water at a high pressure to stored dishes, washes them, and then dries them. Specifically, the dishwasher operates so that washing water is sprayed at high pressure into the tub in which the dishes are accommodated, and the sprayed washing water comes into contact with the dishes to wash foreign substances such as food residues on the surface of the dishes.

A dishwasher generally includes a tub forming a washing chamber and a sump mounted on the bottom of the tub to store washing water.

Then, the washing water is moved to the jet arm by the pumping action of the washing pump mounted inside the sump, and the washing water moved to the jet arm is injected at a high pressure through the jet port formed in the jet arm.

Then, the washing water sprayed at high pressure collides with the surface of the washing target, and the dirt on the washing target falls to the bottom of the tub.

Such a dishwasher is configured to filter food waste contained in the washing water by a filter, recycle the used washing water, and dissolve the detergent into the washing water, so that the food waste can be smoothly separated.

The washing pump 60 may include an impeller for pressurizing washing water and a motor for rotating the impeller. When the impeller and the motor operate and rotate, vibration may occur in the washing pump 60 , and this vibration may be transmitted to the sump 40 and the sump 40 may also vibrate.

The vibration of the washing pump 60 and the sump 40 may cause noise. Therefore, in order to suppress the vibration of the washing pump 60 and to suppress the vibration of the washing pump 60 from being transmitted to the sump 40, a coupling mechanism capable of suppressing the vibration is used to suppress the vibration of the washing pump 60 and the washing pump 60. It is necessary to engage the sump 40 .

If the coupling mechanism is made of, for example, a low-rigidity and flexible material, for example, a rubber material, there is an advantage in that the vibration of the washing pump 60 can be effectively absorbed.

However, when a rubber coupling mechanism is used, a large position change may occur between the washing pump 60 and the sump 40 when the dishwasher is transported or moved due to the flexibility and low rigidity of the rubber.

Due to such a large change in position, there is a risk that the washing pump 60 or the sump 40 may be damaged. Therefore, the coupling mechanism needs to have a certain rigidity so that a large position change does not occur between the washing pump 60 and the sump 40 .

Therefore, in the embodiment, a flexible material capable of effectively absorbing the vibration of the washing pump 60 and a sufficient material capable of suppressing the occurrence of a large position change between the washing pump 60 and the sump 40 have a combined structure. , a holding mechanism 100 for coupling the washing pump 60 to the sump 40 is proposed.
