Ultrasonic vibrator mounting structure of dish washing machine

Abstract

The invention discloses an ultrasonic vibrator mounting structure of a dish washing machine. The ultrasonic vibrator mounting structure comprises an inner container, a fixing support and an ultrasonicvibrator, the fixing support is arranged below the bottom of the inner container and fixedly connected with the inner container, the ultrasonic vibrator is arranged on the fixing support, and the topface of the vibration face of the top of the ultrasonic vibrator is tightly attached to the outer side face of the bottom of the inner container. The ultrasonic vibrator is simple in installation structure, and the vibration surface of the top of the ultrasonic vibrator is always tightly attached to the outer side surface of the bottom of the inner container, so that the ultrasonic transmission effect between the ultrasonic vibrator and the inner container of the dish washing machine is effectively guaranteed; besides, compared with the prior art that a conventional ultrasonic vibrator is installed at the hole in the bottom of the inner container, the invention has the advantages that the bottom of the inner container does not need to be provided with a hole, so that a sealing ring is omitted, the manufacturing cost is reduced, the water leakage risk caused after the sealing ring is aged can be avoided, and the use safety of the dish washing machine is further improved.

Description

technical field [0001] The invention relates to the technical field of dishwashers, in particular to an installation structure of ultrasonic vibrators for dishwashers. Background technique [0002] With the improvement of living standards, dishwashers are gradually becoming popular in families due to their convenient operation and superior cleaning performance. In order to improve the cleaning performance of the dishwasher, ultrasonic waves are often installed on the dishwasher. In the prior art, an opening is provided at the bottom of the dishwasher liner for installing an ultrasonic vibrator. The ultrasonic vibrator is installed in the opening through an external thread and a nut. At the hole, in order to avoid water leakage at the joint between the hole and the ultrasonic vibrator, a sealing ring needs to be provided, which has a complex structure and high cost.

In order to improve the cleaning performance of the dishwasher, ultrasonic waves are often installed on the dishwasher. In the prior art, an opening is provided at the bottom of the dishwasher liner for installing an ultrasonic vibrator. The ultrasonic vibrator is installed in the opening through an external thread and a nut. At the hole, in order to avoid water leakage at the joint between the hole and the ultrasonic vibrator, a sealing ring is required, which has a complex structure and high cost

In addition, the oil stain inside the dishwasher will have a corrosive effect. After the dishwasher has been used for a long time, the sealing ring will age, and there is still a risk of water leakage, which will affect the performance of the dishwasher.
