Description

  The present invention relates to a vacuum ultrasonic cleaning apparatus in which a housing is provided with a cleaning tank and a lid member provided with a vacuum pump is mounted on an ultrasonic cleaning machine in which a piezoelectric vibrator is mounted on the cleaning tank.

  A conventional small tabletop ultrasonic cleaner is configured to have a cleaning tank mounted inside the housing and a piezoelectric vibrator mounted to the bottom of the cleaning tank. The top of the cleaning tank is released, and cleaning liquid is supplied to the cleaning tank. Putting them in and cleaning glasses or watch bands or small bags.

However, in the conventional small tabletop ultrasonic cleaner configured as described above, the inside of the cleaning tank is generally not evacuated. In order to evacuate the inside of the cleaning tank, the vacuum pump is installed in the housing. In order to remove air from the cleaning tank, an air vent must be installed in the cleaning tank, and the configuration of the small tabletop ultrasonic cleaner must be changed significantly. is there.
JP 7-116620 A

  The problem to be solved is that a conventional small tabletop ultrasonic cleaning machine has a problem that the configuration must be largely changed in order to form a vacuum ultrasonic cleaning machine.

  In the present invention, the ultrasonic cleaning machine is configured such that the housing is integrally attached to the top of the cleaning tank, the piezoelectric vibrator is attached to the bottom of the cleaning tank, and the oscillator applies an oscillation output to the piezoelectric vibrator. The lid member is provided with a hermetic packing at the top of the housing, a vacuum pump connected to the air vent at the center, and an oscillator and a power source for supplying power to the vacuum pump.

  In the vacuum ultrasonic cleaning liquid device of the present invention, the lid member is configured to be sealed on the upper part of the housing via a packing, and a vacuum pump is attached to the lid member so that the air vent connected to the vacuum pump is placed under the lid member. By attaching the lid to the top of the housing where the cleaning tank of the ultrasonic cleaning machine is attached, the inside of the cleaning machine tank can be easily evacuated by driving the vacuum pump. By connecting a solenoid valve to the air vent and controlling (switching) the solenoid valve with a timer, it is possible to peel off bubbles and dirt in the hole in the short time.

  In the present invention, by attaching a vacuum pump and air vent to the lid member, the conventional ultrasonic cleaner can be easily changed as a vacuum ultrasonic cleaner.

  1 is a side sectional view of a vacuum ultrasonic cleaning apparatus according to an embodiment of the present invention, FIG. 2 is a plan view of a lid member, FIG. 3 is a side sectional view of the lid member, and the upper periphery of the cleaning tank 2 is fixed to the housing 1 Then, the piezoelectric vibrator 3 is attached to the bottom of the cleaning tank 2, and the oscillation output is applied to the piezoelectric vibrator 3 from the oscillator 4 attached to the bottom of the housing 1, and the cleaning liquid is applied to the bottom of the cleaning tank 2. A discharger 5 for discharging is mounted, and a lid member 6 is hermetically sealed at the top of the housing 1 by a packing 7. A vacuum pump 8 is built in a mounting portion 6 a formed at the center of the lid member 6. An air vent 8 a connected to 8 protrudes below the lid member 6, and the vacuum pump 8 and the oscillator 5 are connected to a power source 9.

  In the vacuum ultrasonic cleaning apparatus of this embodiment configured as described above, the lid member 6 at the top of the housing 1 is removed, the cleaning liquid and the object to be cleaned are placed in the cleaning tank 2, and the lid member 6 is placed at the top of the housing 1. When the vacuum pump 8 is differentially covered, the air in the cleaning tank 2 is extracted from the air vent 8a, and the cleaning tank 2 is evacuated. Is applied, the inside of the cleaning tank 2 can be cleaned in a vacuum state, so that it is possible to clean fine holes and bag holes that were not partitioned in the normal pressure state, and large bubbles are removed during cleaning, Stronger cavitation can be obtained, and the cleaning power becomes stronger, so that there is an advantage that the cleaning time is shortened. In addition, air is supplied into the cleaning tank 2 by the pressure relief valve 10 to obtain normal pressure. This It makes it possible to remove the lid member 6 simply allows cleaning with normal pressure.

  FIG. 4 is a plan view of a lid member of a vacuum ultrasonic cleaning apparatus according to another embodiment of the present invention, wherein 6 is a lid member, 8 is a vacuum pump, 10 is a pressure relief valve, and these configurations are the same as in the above embodiment. Therefore, although explanation is omitted, in the present embodiment, the electromagnetic valve 11 is mounted between the vacuum pump 8 and the air vent 8a, and this electromagnetic valve 11 is turned on / off every time determined by the controller 12. It is configured as follows.

  In the vacuum ultrasonic cleaning apparatus of the present embodiment configured as described above, the electromagnetic valve 11 is turned on / off by the controller, and the vacuum and normal pressure are controlled at predetermined time intervals. The dirt can be removed in a short time.

  In addition, in the said Example, although the housing 1 and the washing | cleaning tank 2 are comprised separately, what comprised the housing 1 and the washing | cleaning tank integrally may be sufficient.

It is side surface sectional drawing of the vacuum ultrasonic cleaning apparatus of the Example of this invention. It is a top view of the cover member of FIG. It is side surface sectional drawing of the cover member of FIG. It is a top view of the cover member of the vacuum ultrasonic cleaning apparatus of the other Example of this invention.
