Description

Plate rinse washer

The present invention relates to a plate rinsing and washing device, and more particularly, while sequentially moving the plates immersed in the immersion detergent solution and pre-washed in the longitudinal direction along the tunnel space, high-pressure washing water and rinsing water are applied to the surface of the moving plate. It relates to a plate rinsing washing device that washes and rinses foreign substances and detergent solution remaining on the surface of the plate by high-pressure spraying.

In general, a dishwasher is to automatically wash and dry a large amount of tableware, for example, plates, soup bowls, plates, etc., and is mainly installed and used in large-scale restaurants or group cafeterias such as hotels, hospitals, schools, factories, military, etc.

A typical dish washing machine in the prior art includes a tunnel-type washing space, a plate transfer unit for moving the plates in an upright state along the tunnel-type washing space, and a high pressure on the surface of the plate passing through the washing space along the plate transfer unit. It is configured as a rinsing washing water jetting type including a jet nozzle for jetting rinsing washing water.

The plate transfer unit is attached in the form of an endless track between the driving shaft, the driven shaft, and the driving shaft and the driven shaft, and is continuously pulled in one direction by the one-way rotation of the driving shaft and moved, and the plates seated through the support fingers are erected. It is composed of a conveyor structure including a plate transport belt that is arranged in each state.

Therefore, the plates seated on the plate transport belt of the plate transport unit sequentially pass through the tunnel-type washing space in which the spray nozzle is disposed by the traction transport action of the plate transport belt, and in this process, the plates placed in the tunnel-type washing space The plates are rinsed and cleaned by the rinse-cleaning liquid sprayed through the spray nozzle, so that foreign substances or detergent solution remaining on the surface are removed.

On the other hand, the present inventor circulates the soaking detergent solution stored in the soaking tank in the soaking tank to form a water flow without the hassle of directly rubbing the dish plate with a scrubber, etc. As much as possible, a water-flow immersion type plate washer has been proposed.

As described above, with the development and dissemination of the water-immersion type dish washer, the hard labor caused by the worker rubbing the surface of the dish with a loofah, etc. was resolved, and by immersion cleaning of the dish using a water current, stable pre-cleaning of foreign substances without operator intervention this has been accomplished

Therefore, in the art, by sequentially arranging a water-flow immersion-type plate washer and a rinse-washing-water spraying-type plate washer, the plate immersed in the water-flow immersion-type plate-cleaning device is put into the rinse-washing-water spraying-type plate washer, and the primary washing is completed. By rinsing and discharging, it has improved efficiency according to the washing of the plate.

However, since an appropriate amount of the immersion detergent is dissolved in the immersion detergent stored in the water-flow immersion type plate washing device, the detergent solution of the immersion detergent remains on the surface of the plate after preliminary washing.

In particular, an organic surfactant component or an inorganic surfactant component is incorporated in the immersion detergent, wherein the organic surfactant component has a property that cannot be easily removed.

Therefore, when an actual water-flow immersion-type plate washer and a rinsing washing-water spray-type plate washer are disposed to sequentially wash and rinse the plate, a phenomenon in which some detergent solution remains on the surface of the plate after washing and rinsing has been found.

On the other hand, the plate transport belt of the plate transport part of the conventional rinsing washing water injection type plate washer is configured to move only in the horizontally deployed state in the rinse washing section, and as a result, it is disposed on the plate transport belt to support the plate in an inclined manner. The fingers always support the plate at a certain angle.

Therefore, the plates seated on the plate transport belt always move in the rinsing washing section while maintaining a constant angle. Washing blind areas are inevitable.

Such a washing blind area may be formed by adjacent plates or by a standing angle. However, if a washing blind area to which the rinsing washing water does not reach occurs, it is difficult to achieve stable rinsing and washing of dishes.

The bending roller unit 50 includes a lifting support roller 51 that upwardly supports the bottom surface of the plate transport belt 23 to bend the supported plate transport belt 23 in an arcuate shape, and preferably supports the elevation. By disposing compression support rollers 52 downwardly supporting the upper both sides of the plate conveying belt 23 bent in an arcuate shape by an elevating support roller 51 at the front and rear of the roller 51, the bending roller part ( The plate conveying belt 23 passing through 50 is bent to be standardized along the trajectory formed between the lifting support roller 51 and the pressing support roller 52 .

In this embodiment, the plate transport belt 23 on the moving path of the plate transport belt 23 is horizontally expanded and moved in the horizontal movement section (CL) and the plate transport belt 23 by the bending roller unit 50 . ) continuously forms a curved transfer section (CA) in which it is deformed and moved vertically.

Therefore, the plate transport belt 23 of the plate transport unit 20, which is arranged to stand upright by the bending roller unit 50 and moved in one direction, is bent by the bending roller unit 50 and the plate ( The support angle of T) is changed in the front-rear direction, and as a result, the plates (T) passing through the tunnel space part 10 do not maintain a standing state only at a certain angle, but form various front and rear standing angles in the process of passing.

Thus, the plates (T) seated on the plate transport belt (23) have a deformed standing angle that passes through the tunnel space part (10) through the bending roller part (50), so that the plates (T) are sprayed through the spray nozzle part (30). Evenly spraying of rinsing water and washing water can be achieved on each part of the plates T without generating a dead area where rinsing water and washing water are not sprayed.

In particular, both sides of the plate transport belt 23 bent upward in an arcuate shape by the elevating support roller 51 are compressed by the compression support roller 52, and are bent in a standardized trajectory to support the plate T. angle will change.

In addition, in this embodiment, as shown in FIG. 4 , the upper portion of the dining plate transfer belt 23 bent by the bending support unit 50 elastically supports the upper portion of the dining plate T, whose standing angle is changed, the dining plate (T). An elastic interference member 53 is disposed to prevent them from falling forward.

Here, the elastic interference member 53 may be adopted in various forms for elastically supporting the upper portion of the plate, such as an elastic pad made of an elastic material or a tanji arm having elasticity.

If the elastic interference member 23 is not provided as shown in FIG. 5 showing a comparative example, the plate T passing through the bending transfer section CA by the bending roller part 50 intermittently tilts forward excessively. As a result, a phenomenon of falling forward occurs due to inertia, but as shown in FIG. 4 , if the elastic interference member 23 is provided, the phenomenon that the plate is tilted forward excessively is prevented, so the phenomenon that the plate (T) falls forward This can be prevented.

Therefore, the plates (T) that are arranged to stand upright on the plate transport belt 23 and pass through the tunnel space part 10 while being pulled and moved in one direction by the one-way rotation of the driving shaft 21 are curved roller parts 50 While passing through the curved support section (CA) in which is formed, it moves in a bent up and down state, and in this process, the standing angle of each support finger 24 disposed on the plate transport belt 23 is temporarily changed.

That is, the plate transport belt 23 forms a flatly deployed state in the horizontal transport section (LA) section, so that the support fingers 24 maintain a standardized support angle to support the plate (T), and the bending roller unit In the bending transfer section CA where 50 is formed, it is deformed to be bent up and down to temporarily change the standing angle of the plate T by the support fingers 24 connected to the chain link structure.

Thus, the eating plates (T) supported by each support finger 24 while passing through the bending transfer section (CA) change the standing angle, the standing height, and the spacing between the plate (T), the plate (T) The rinsing water and washing water sprayed through the spray nozzle unit 30 are met at various angles.

Accordingly, the plates (T) passing through the tunnel space portion 10 by the plate transfer unit 20 form various standing angles and standing heights, so that the rinsing water and washing water are not sprayed. Even spraying of rinsing washing water is achieved on each part of (T), so that even rinsing washing of the plates (T) is achieved.

In particular, when the plate transport belt 23 is locally bent up and down by the bending roller unit 50 , the plates T supported in a standing state on the plate transport belt 23 are mutually fluid at a standing angle. In this process, the rinsing water and the washing water sprayed from the spray nozzle unit 30 penetrate between the plates (T) with different intervals to achieve stable rinsing and washing of foreign substances remaining on the surface of each plate (T). there is.

At this time, the plate T, which is seated on the plate transport belt 23 bent by the bending support 50 and the standing angle is changed, includes an elastic interference member 53 disposed on the upper portion of the bending support section CA and When elastically interfered, the support state by the support finger 24 is poor, and the plate T is prevented from falling forward.
