Description

[Detailed explanation of the idea] This invention relates to an improvement of a washing machine for root vegetables.

As shown in FIGS. 1 and 2, a conventional washing machine of this type has a cap on the top of a rotary shaft that is vertically rotatably installed in the center of a square tubular washing tank a with a bottom. It is equipped with a shaped brush C, and as the brush C rotates, water d in the cleaning tank a collides with the corner of the cleaning tank a, causing it to rise in a wavy shape and forming the water in the cleaning tank a. Let it bounce back to the center,
The brush C was used to wash root vegetables using the circulation of water d.

However, with this type of structure, the circulation speed of the water d tends to be delayed compared to the rotation of the brush C, and the speed decreases proportionally as the objects to be cleaned are thrown in, resulting in cleaning performance. There was a problem in that the value decreased significantly.

In addition, when trying to increase the rotation speed of brush C to solve this problem, the power consumption increases at an accelerated rate, but the circulation speed of water d does not increase, but rather causes turbulence, resulting in a loss of horsepower. There has been a problem in that the inconvenience of increased size occurs.

This idea was developed in view of the above circumstances, and the brush is divided into upper and lower halves, and the rotation speed of the cap-shaped upper brush, which is lower than the height of the lower brush to reduce water resistance, is lower than that of the lower brush. By increasing the rotation speed to a higher speed than the rotational speed, it is possible to wash only the items to be washed at high speed, and the root vegetables can be washed efficiently with less horsepower loss. The aim is to provide a washing machine.

Examples of this invention will be described below with reference to FIGS. 3 to 6.

In the figure, reference numeral 1 denotes a cleaning tank, which is formed almost in the shape of a rectangular cylinder with a slightly rounded corner.
A concentric inner rotating shaft 2 and a hollow outer rotating shaft 3 are rotatably installed in the center of the bottom 1', and these rotating shafts 2 protrude downward from the bottom 1'. , 3 are equipped with a small-diameter driven pulley 7 and a large-diameter driven pulley 8, which respectively carry a transmission belt 6, 6 mounted on a drive pulley 5 mounted on a drive shaft 4' of a motor 4. has been done.

In this case, by setting the smaller diameter driven pulley 7 to approximately 172 times the larger diameter driven pulley 8, the rotation speed of the inner rotation shaft 2 can be set to approximately twice the rotation speed of the outer rotation shaft 3. .

A cylindrical lower brush 10 is attached to the upper end of the outer rotating shaft 3 via a bracket 9, and the lower brush 10 is attached to the upper end of the inner rotating shaft 2 that projects upward from the inner rotating shaft 3. A cap-shaped upper brush 11 having an arcuate top and a height lower than the height H of 10 is attached.

In the cleaning machine of this invention constructed as described above, the cleaning brush is a two-part type consisting of an upper brush 11 and a lower brush 10, and the upper brush 11 is lower in height than the lower brush 10. The resistance of the water 12 is made as small as possible, and the rotation speed is approximately twice that of the lower brush 10, so that the object to be cleaned 1 can be cleaned without loss of horsepower.
Only 3 can be cleaned at high speed.

In this case, as shown in FIG. 6, the upper brush 11 and the lower brush 10 are formed into a tapered shape that becomes narrower toward the top, so that the lower brush 10 is spaced appropriately from the lower end to the upper end. Speed at position ■1. v2.

In addition, the flocked hairs 11', 11', which constitute the upper brush 11 are

On the other hand, in the lower brush 10, a rotating flow is applied to the water 12, so that the object 13 to be cleaned can be efficiently cleaned.

As explained above, in the cleaning machine of this invention, the cleaning brush is divided into upper and lower halves, and the rotation speed of the cap-shaped upper brush, which is lower than the height of the lower brush to reduce water resistance, is lower than that of the lower brush. Since the rotation speed is set higher than the rotation speed of the brush, it is possible to wash only the object to be cleaned at high speed, and it is possible to eliminate horsepower loss and power consumption. Since it is possible to form a whirlpool, it has excellent effects such as being able to efficiently and evenly wash the root vegetables that are to be washed, and its utility value is remarkable.
