2. Description of the Related Art Plastic containers are widely used as containers for transporting milk bottles, lunch boxes for lunch, and the like. These containers deliver milk, lunches, and the like to stores and offices, and then collect empty milk bottles, lunch boxes, and the like and take them back. This brought back container is washed and used repeatedly.

[0003] The above-mentioned plastic container is usually formed with a fold at the upper edge of the side wall in order to make it easier to hold by hand, also serving as reinforcement. In addition, the side walls are slightly tapered and spread upward to facilitate the removal of the mold during molding.

In washing the above-mentioned container, it is necessary to drain and dry the container after the washing. Conventionally, in order to perform this draining and drying, a blower or the like is attached to the cleaning device to ventilate the humid cleaning case,
Air or hot air is blown on the container in the cleaning case. In addition, a drying apparatus having a compressor or a hot air blower may be used separately from the cleaning apparatus.

[0005] The above-described conventional method requires an expensive blower and a dedicated drying device, and thus has a problem that equipment costs are increased.

An object of the present invention is to provide an inexpensive centrifugal dewatering type washing apparatus which does not require any drying equipment.

[0007]

In order to solve the above-mentioned problems, a centrifugal dewatering type washing apparatus of the present invention drives a washing case, a rotating shaft protruding from the bottom of the washing case, and the rotating shaft. A motor, a mounting table attached to the upper end of the rotating shaft, a fixture for fixing an object to be cleaned to the mounting table, and a nozzle for spraying cleaning water toward the mounting table are employed.

That is, after the object to be cleaned fixed on the table is washed by the washing water injection nozzle, the object to be cleaned is drained by using a rotating shaft at a high speed and centrifugal force. Is dried by cutting off the wind.

By configuring the mounting table with a frame, objects to be cleaned of different sizes can be efficiently cleaned without interrupting cleaning water injected from below.

[0010] By providing an exhaust hole on the side of the side of the cleaning case where the object to be cleaned comes along with the rotation, and an intake hole on the side where the object to be cleaned escapes with the rotation, the object to be cleaned is provided. Utilizing the wind caused by the rotation of the object, the humid air in the cleaning case can be exhausted from the exhaust port, and the external dry air can be taken in from the intake port to ventilate the object. Can be performed more efficiently.

An arm extending on both sides of a fulcrum is formed as the fixing tool. A hook is provided at a tip of one arm, and a weight is provided at a tip of the other arm. By adopting a structure in which the fulcrum is rotatably attached to the mounting table in a direction away from the rotation center of the shaft, the weight is lifted by centrifugal force during rotation of the object to be washed, and the hook is washed. When the object gets caught on the edge of the object and the rotation of the object to be cleaned stops, the weight is lowered and the hook is lifted from the edge of the object to be cleaned, so that the object to be cleaned can be automatically fixed to the table and released.
