Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a washing machine for washing objects such as bulbous vegetables such as potatoes and carrots and simple-shaped mechanical parts.

(Prior art) Traditionally, for example, in processed food factories, it was necessary to wash large quantities of bulbous vegetables, etc., so a large amount of potatoes, etc., were placed in a wire mesh storage basket and the basket was rotated to wash. As disclosed in Japanese Patent No. 45110, an inner tank is provided within an outer tank, and cleaning is performed using a rotating brush installed at the bottom of the inner tank.

(The problem that the invention aims to solve) However, in the former example, it takes a long time to completely wash the items located in the center, and in the latter example, the rotating brush built into the inner tank only rotates. However, it has the disadvantage that it cannot be cleaned thoroughly.

An object of the present invention is to provide a washing machine that can thoroughly wash a large amount of potatoes, etc., efficiently and in a short period of time.

(Means for Solving the Problems) The present invention consists of a cleaning tank 3 with an open top and a screw plate 1 rotatably provided at the inner bottom of the cleaning tank.
2, a storage basket 5 rotatably supported above the screw plate, and rotation drive means 8, 9, 10, 11, 13 for rotating the screw plate and the storage basket in mutually opposite directions; The brush rod 14 is provided vertically within the storage basket.

(Function) By the operation of the rotation drive means 8, 9, 10, 11, and 13, the storage basket 5 is rotated within the cleaning tank 3, and the screw plate 12 is also rotated at the same time. At this time, since the screw plate 12 and the storage basket rotate in opposite directions, a vortex is generated in the cleaning water in the cleaning tank, thereby enhancing the cleaning effect. Further, since the brush rod 14 is vertically installed inside the rotating storage basket 5, it is possible to sufficiently clean objects to be cleaned in the central part of the inside of the storage basket.

(Example) Examples of the present invention will be described below.

In FIG. 1, a lid 2 is hinged to one side of the upper opening edge of an outer case 1, and inside this outer case, a cleaning tank 3 with an upper opening is provided, and a plurality of support columns 4,
Supported by 4. A storage basket 5 is removably inserted into the cleaning tank 3, and this storage basket is removably connected to a rotary plate 6 disposed at the bottom of the cleaning tank 3. It is. The center of the lower surface of the rotary plate 6 is supported by a cylindrical shaft 7, and the rotary drive means for this shaft is a drive pulley 9 of a drive motor 8 supported by one of the support columns 4. The pulley 11 of the speed reduction mechanism 10 is rotated in conjunction with the speed reduction mechanism 10, and the shaft 7 is rotationally driven through this speed reduction mechanism.

In the speed reduction mechanism 10, the rotational driving force of the drive motor 8 is branched, and one side rotates the shaft 7 as described above, but at the same time, it passes through the hollow part of this shaft and extends above the rotating plate 6. The drive shaft 1 connected to the lower center of the screw plate 12 located at
3 is also rotated. The screw plate 12 has protrusions radially formed on its upper surface, and is driven to rotate in the opposite direction to the rotary plate 6.

Further, in the center of the storage basket 5, a brush rod 14 having brushes radiating outward is vertically disposed so as not to come into contact with the storage basket. It is fixed to a support arm 15 which is installed between the edges of the upper opening and is locked. A drain hole 16 is provided at the outer corner of the bottom of the cleaning tank 3, and a drain pipe 1 with a valve is provided in this hole.
7 are connected.

Next, to explain how to wash potatoes P, the storage basket 5 is placed in the washing tank 3 in advance, and this storage basket is locked to the rotary plate 6. Then, the brush rod 14 is positioned at the center of the storage basket, the support arm 15 is locked to the upper opening edge of the cleaning tank 3, and the potatoes P are thrown into the storage basket 5.

Therefore, when the drive motor 8 is driven to rotate after pouring into the cleaning tank 3, the storage basket 5 rotates in the cleaning tank 3, and a vortex is generated, which not only affects the potatoes P located on the outer periphery but also inside. The potatoes located are also cleaned by the brush rod 14.

Since the screw plate 12 rotates in the opposite direction to the rotation direction of the storage basket 5, the vortex becomes even stronger and the cleaning effect is further improved. In particular, intermittently reversing the rotational directions of the storage basket 5 and the screw plate 12 is also effective in increasing the cleaning effect.

(Effects of the invention) According to the invention, since the brush rod is installed vertically in the rotatable storage basket, even if the items to be cleaned are irregularly placed in the storage basket, they can be cleaned even if they are placed in the center of the storage basket. The screw plate and storage basket rotate in opposite directions, creating a whirlpool in the cleaning water in the cleaning tank, allowing for efficient and thorough cleaning in a short period of time, saving energy for the drive motor and extending its life. It is effective in
