Description

HOUSEHOLD CLEANER FOR FRUITS OR VEGETABLES}

The present invention relates to a household spraying fruit and vegetable washer, and to a washing by ultrasonically vibrating the washing water, it relates to a household spraying fruit, vegetable washer that can be cleaned cleanly and hygienically as well as preventing damage to the cleaning object.

Today, with the development of industrial technology and the improvement of culture level, the concept of convenience and hygiene of people is increasing day by day, while the demand for environmental protection and improvement is increasing day by day due to severe environmental pollution. However, in the kitchens everywhere, such as homes, businesses, factories, offices, etc., it was not possible to develop a cleaning device that satisfies these conveniences and hygiene as well as environmental protection. In addition, the development of a device that can prevent the environmental pollution due to waste of detergent and water while the cleaning is urgently required.

In general, when cleaning fruits or vegetables with water from a kitchen water supply, fruits or vegetables with thick or smooth skin It can be cleaned, but fruit or vegetable with thin skin or uneven surface can be cleaned at the part where the washing water touches, but not at the part where the washing water does not touch, so it can not achieve the cleaning effect as desired. In addition, the cleaning efficiency cannot be increased by only relying on the washing water freely falling from the water supply port, and since the washing is performed by hand rubbing, there is a problem of damaging the epidermis such as fruits or vegetables.

Therefore, conventionally, there has been an effective cleaning method for removing pesticides or other contaminants on fruits or vegetables by putting detergent in water in a certain container and then cleaning the fruits or vegetables.

However, the side effects of environmental pollution due to waste of detergent and water, and also when the epidermis of the fruit or vegetable has an uneven surface, there is a problem in that the detergent remains on the epidermis and cannot be hygienic cleaning.

Therefore, an object of the present invention is to solve the above problems, easy and hygienic and environmentally friendly spray type ultrasonic cleaning device by installing the ultrasonic cleaning device in the water supply apparatus installed in the kitchen everywhere, such as homes, businesses, factory offices To provide.

The object of the present invention is a household spray type ultrasonic cleaning apparatus using an ultrasonic vibrator having a space for accommodating the ultrasonic oscillation circuit unit in the housing, which is formed on the side or upper surface of the housing and connected to the household water to receive the washing water. It is connected to the inlet and the inlet, and connected to the pipe-shaped main channel and the outlet side of the main channel used as the channel of the washing water flowing in from the outside, and a plurality of parts to distribute the washing water obtained from the main channel into several branches A water inlet connected to a local channel and an outlet side of each local channel is provided at the side, and has a water outlet for discharging the washing water to the outside at the lower portion, and a plurality of jets having a tapered shape that is narrowed closer to the water outlet. It is supported by the housing on the surface facing the nozzle and the outlet of each injection nozzle. And a plurality of ultrasonic vibrators for applying ultrasonic waves to the washing water temporarily stored in the spray nozzles and a power supply line for supplying the outputs of the ultrasonic oscillator circuits to the ultrasonic vibrators. Do.

It is.

Also preferably, a gasket 36 is further included on the periphery of the ultrasonic vibrator 34 according to the present invention to prevent the washing water of the reservoir 60 from leaking into the ultrasonic oscillation circuit portion. This is because when the water storage part 60 is filled with the washing water, the washing water may leak into the gap between the ultrasonic vibrator 34 and the case 10 due to the water pressure and may flow into the ultrasonic oscillation circuit part 32. Typically, the ultrasonic vibrator 34 is bonded to the metal vibrating unit, the metal vibrating unit is integrated using an adhesive or bolt and heat is generated by the vibration in the process of transmitting the vibration of the ultrasonic frequency band generated by the ultrasonic vibrator 34. Will be released. Therefore, the leak-proof gasket 36 according to the present invention preferably uses a material having excellent heat dissipation performance, and particularly preferably uses a viton rubber having excellent heat dissipation performance and hardness characteristics.

An ultrasonic vibrator 34 is disposed inside the case 10, and a metal plate serving as a terminal for applying an input power and a signal voltage to the ultrasonic vibrator 34 from the ultrasonic oscillator circuit 32 on a plane of the ultrasonic vibrator 34. There is 38. The leakage preventing gasket 36 is interposed around the ultrasonic vibrator 34 to close a gap between the case 10 and the ultrasonic vibrator 34, so that the washing water is ultrasonic when the reservoir 60 is filled with the washing water. It is a structure which prevents the leakage by the oscillation circuit part 32.

However, when the spray type ultrasonic cleaning device disclosed in Patent Application No. 2001-39491 is used to wash vegetables or fruits, the inconvenience of using the spray nozzle 70 is small, which takes a long time to wash. This problem may be inferred in consideration of the size of the spray nozzle 70 is about 4 mm and the size of the vegetables or fruits to be cleaned. Therefore, the present invention is to provide a household spray type ultrasonic cleaning apparatus capable of washing vegetables and fruits within a relatively short time.
