Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a washing machine for dish-shaped objects such as tableware.

In the present invention, the term "dish-shaped object to be washed" refers to a relatively flat object to be washed, such as eating and drinking plates, trays, other tableware, or ashtrays. 〇 Conventionally, in places where a large number of dish-shaped objects are used such as cafeterias, restaurants, and hotels, food and drink objects that are firmly or closely attached to the dish-shaped objects are excluded. To remove the ring, the plate-shaped object that has been washed (prewashed or prewashed) is placed in a large automatic washing machine, sealed, and thoroughly cleaned by spraying boiling water from multiple directions. However, since automatic washing machines use machines to wash, they may not be completely cleaned, and some damage to the washed body is unavoidable during washing. Currently, they are washed manually and with the utmost care.

Regardless of whether you use an automatic washing machine or manually to clean the edges, the leftover food is emptied into a food bin, then stacked on a table, immersed in many large water tanks, and then placed in a dish-like container. In most cases, the washing body is taken out and washed to remove food or drink slag that is firmly and closely attached to the dish-shaped object to be washed. Therefore, conventional automatic washing machines have had the disadvantage of requiring a large amount of space, equipment, and labor to stack and immerse and take out the objects to be washed. Also, it required a lot of water for soaking. However, washing old trees requires labor, time, and space, and requires great attention to the washing of the object to be washed.
However, even if careful attention is paid to the washing of the object to be washed, there is a drawback that damage to the object to be washed cannot be prevented.

The present invention overcomes the aforementioned drawbacks.

SUMMARY OF THE INVENTION An object of the present invention is to provide a washing machine that easily and reliably washes a dish-shaped object.

An object of the present invention is to provide a washing machine with a simple and robust structure.

An object of the present invention is to provide a washing machine that is lightweight, small, and easy to carry.

An object of the present invention is to provide a washing machine that is easy to use and less likely to malfunction.

SUMMARY OF THE INVENTION An object of the present invention is to provide a washing machine that causes less damage to objects to be washed and is safe for the operator.

An object of the present invention is to provide a sanitary washing machine.

The present invention is a washing machine in which the object to be washed automatically pops out onto the surface of the washing liquid after washing. SUMMARY OF THE INVENTION An object of the present invention is to provide a washing machine that automatically washes dish-shaped objects having a wide range of sizes.

An object of the present invention is to provide a washing machine that saves labor, time, washing water, and occupied space.The present invention provides a washing machine that is installed at a level below the bath surface of the washing liquid in a washing tank filled with washing liquid. It is equipped with two pairs of cleaning brushes that rotate in opposite directions with different angles, and the upper pair of cleaning brushes is inserted between the two cleaning brushes in such a direction as to draw the dish-shaped object to be cleaned between the brushes, and the lower pair of cleaning brushes is This washing machine for a dish-shaped object is connected to a drive system that rotates a pair of cleaning brushes in a direction that pushes the dish-shaped object back by overcoming the retraction force.

In the present invention, the upper pair of cleaning brushes is inserted between the two cleaning brushes in such a direction that the dish-shaped object to be cleaned is pulled between the brushes, and the lower pair of cleaning brushes is inserted in the direction in which the dish-shaped object to be cleaned is pulled in between the brushes, and the lower pair of cleaning brushes is inserted in the direction in which the dish-shaped object to be cleaned is pulled in between the brushes. Since the objects to be cleaned inserted between the upper pair of brushes are automatically drawn into the cleaning liquid with the upper part left intact (see Figure 4), the objects to be cleaned are automatically drawn into the cleaning liquid, leaving the upper part intact. Push the remaining upper part further downward into the cleaning solution, and the cleaning brush will automatically clean both the front and back of the object (see Figure 5).
As soon as the downward push is stopped, the object to be washed will almost immediately reveal its upper part above the surface of the washing liquid (see FIG. 6).

In a preferred embodiment of the present invention, the rotational speed of the cleaning brush pair on the lower stage is set to be higher than the rotational speed of the cleaning brush pair on the upper stage.

In another example of the present invention, the diameter of the lower cleaning brush is made larger than the diameter of the upper cleaning brush, so that when the rotational speed is the same, the lower rotating brush has a larger diameter. Allow your body to be pushed back.

In another example of the present invention, one or more of the thickness and bristle density of the bristles of the lower pair of cleaning brushes are set to be greater than that of the bristles of the upper pair of cleaning brushes.

In another example of the invention, the cleaning brush is replaceable.

In another example of the present invention, the distance between the pair of cleaning brushes can be adjusted. In this way, the pulling force or pushing force of the cleaning brush can be reduced, and if the width is adjusted to a wide width, it becomes extremely easy to clean extremely large or small objects. The intervals are set so that a wide range of medium-sized objects can be washed, excluding small objects. Although it is of course possible to adjust the spacing depending on the shape, size, and material of the extremely large or small object to be washed, the spacing is usually adjusted in advance to suit the medium-sized object as described above. I'll keep it.

If the cleaning action is increased, for example by increasing the cleaning time, the washer of the present invention will function not only as a pre-washing machine but also as a cleaning machine. Therefore, the washer of the present invention can be effectively used in places where a large automatic washer is not available, such as a small restaurant or home.

After the washing process has been completed, the object to be washed is cleaned by passing it through a large washer using clean water such as tap water or hot water. thoroughly cleaned. Next, the water on the cleaned object to be washed is wiped off with a towel.

The invention will now be explained in more detail with reference to the drawings.

1 to 8 show one part of the washing machine of the present invention. In the washing machine 1 shown in Figs. 1 to 8, the washing tank 2 has a total of four washing brushes 8, two in each of upper and lower stages. The cleaning brush 8 has a rotating shaft 4 extending substantially horizontally, and brush bristles 5 attached to the rotating shaft 4. The four cleaning brushes B are driven by drip-proof or waterproof motors M, and the cleaning brushes 8°8 of each stage are rotated in opposite directions to each other via a pulley belt device or gear device (not shown for simplicity). The cleaning brush 8.8 rotates to pull the object W inserted between the brushes downward, and the lower cleaning brushes 8, 8 push the object W inserted between the brushes upward. Rotate to return it (see arrow in Figure 1). If the belt is hung on two cleaning brushes located diagonally above and below, there will be two belts.

The lower cleaning brushes 8.8 are arranged so that the force of the lower cleaning brushes 8, 8 pushing back the object W to be cleaned is greater than the force of the upper cleaning brush 8.8 pulling the object W downward. The rotational speed of the upper cleaning brush 8.8 is set to be the rotational speed of the upper cleaning brush 8.8. For this reason, the diameter of the pulley fixed to the rotating shaft 4 of the lower cleaning brush 8 is made larger than that of the pulley fixed to the rotating shaft 4 of the upper cleaning brush 8.

The washing tank 2 is supported by a support frame, and the motor M is connected to the washing tank 2.
It is installed on a support frame below the washer, which stabilizes the washing machine and prevents the motor from coming into direct contact with the often wet surfaces of the kitchen. This is to ensure the safety of the operator.

The rotating shaft 4G: t of the cleaning brush B is supported by a watertight bearing IO installed in the center of an internal seal plate 12 that projects eight bolts 11 outward. The rotary brush rotating shaft number and eight bolts 11 can protrude outward from the cleaning tank B, and the same horizontal position 1! 2. The adjustable mechanism has a horizontally elongated brush rotation shaft slot 1B (see Figure 2) and a bolt slot 14. An outer sealing plate 16 having approximately the same diameter as the inner sealing plate 12 can be placed over the opening 14 from the outside. External seal plate 16
There is a center hole 17 and 8 bolts for the 7397 rotating shaft.
The brush rotating shaft 4 supported by a bearing 10 fitted in an O internal sealing plate 12 with a peripheral hole 18 for cleaning is inserted into the cleaning tank 2.
After passing the eight bolts 11 of the inner seal plate 12 through the groove holes 14 of the cleaning tank 2 and the peripheral holes 18 of the outer seal plate 16 through the groove holes 18 of the outer seal plate 16. By screwing the eight nuts 19 onto the bolts 11 and tightening them, the brush rotation shaft slot 18 and the bolt slot 14 of the cleaning tank 2 are connected to the inner seal plate 1B and the outer seal plate 16.
(See Figure 8). Optionally, a watertight backing or washer may be used to increase watertightness. By loosening 19B, the distance between the rotating brushes 8.8 can be reduced to 11. The adjustment range is maximally l Q mm.

When the brush bristles 5 of the rotating brush 8 are worn out or lose their elasticity, or when the area of the object to be washed is extremely large or small compared to the normal size, when cleaning a large amount of objects to be washed,
It is possible to adjust the distance between the inner seal plate 16 and outer seal plate 16 of one of the upper cleaning brushes and the other cleaning brush facing the other cleaning brush by loosening the 8 nuts) 19. This can be done by adjusting the push back force of the lower brush.

A drain hole 20Ti with a stopper 21 is provided at the bottom or side surface of the lower part of the washing tank 2, and a filter 22 or 22' for filtering kitchen dust is provided on the front surface of the drain hole 20Ti to prevent the drain hole 20 from being blocked. The filter 22 or 22' is detachably provided to prevent clogging and to be cleaned at any time. The motor M is started and stopped by a manual switch (not shown). Or start and stop automatically. For example, the bearings 10 of the upper rotating brushes 8, 8 are supported so as to be slidable laterally in the slot 1B, and a spring B is suspended between the bearings 10.
When the body to be washed is inserted between the cleaning brushes 8 and 8, the suspension spring expands and the switch circuit of the motor M is closed, while when the cane is pulled up, the suspension spring contracts and the switch of the motor M is closed. Open the circuit. Alternatively, instead of a manual switch, a photoelectric relay switch that senses the presence of the object to be washed or a hand is used.

The washing machine of the present invention is operated as follows: When the object to be washed, W, is inserted from above between the washing brushes rotating in the washing liquid, the object to be washed, P sinks in the cleaning tank due to the pulling force, and is pushed back by the pushing force of the lower cleaning brush, resulting in the state shown in FIG. 4. Next, when the object W to be washed is pushed into the washing liquid by pushing the upper end of the object W by hand, the front and back surfaces of the object W to be washed are washed by the four cleaning brushes. When the user releases his/her hand after sufficient washing has been completed, the upper part of the object W to be washed will again appear above the surface of the washing liquid due to the pushing back force of the lower washing brush (see FIG. 6). Next, hold the upper end of the object to be washed and pull up the object to be washed. The lifted object to be washed is exposed to flowing tap water or warm water for several seconds to remove the washing liquid and clean it.

@Figure 7 shows the case where the washing machine of the present invention is a porta-pull type and is placed on a household sink S. The motor M is of a waterproof type and is installed at the top of the washing tank 2 near a corner. support,
The leg L' can be omitted, □.,

When installed on the kitchen floor, the dimensions of the washing tank 2 are, for example, about 45 crn in length, about 45 crn in width, and about 60 crn in length. The height of the support frame is about 70 to 90 crn, and can be adjusted as appropriate depending on the height of the user. Household sink S
If it is placed on top, the overall dimensions should be reduced to make it smaller. The washing tank 2 may be provided with an overflow hole (optional).

If the bristles 6 of the cleaning brush become worn or lose their rigidity, they can be easily replaced with a new cleaning brush by removing the LL bin 2B (see Figure 8). When the brush bristles 51 are removably fixed to the brush rotation shaft 4 as a cylindrical body, the brush bristles 5
Only can be easily replaced - so economical.

The washing machine of the present invention has a simple structure, is easy to use, has almost no trouble, is lightweight and small, is easy to install or carry, is less likely to damage the object to be washed, and requires less water, labor, time, and space for washing. It is hygienic, safe for the operator, and can automatically wash a wide range of objects.When the washing is finished, the objects to be washed automatically pop out onto the surface of the cleaning solution. Therefore, the present invention has a very large practical effect and is extremely useful industrially.

Although the invention has been described with reference to specific examples, it will be understood that various changes and modifications may be made without departing from the broader spirit and scope of the invention.
