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, and the military.

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 the 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 conveying belt that is arranged in each state.

Therefore, the plates seated on the plate transport belt of the plate transport part sequentially pass through the tunnel-type washing space in which the spray nozzle part 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 part The plates are rinsed and cleaned by the rinse-cleaning liquid sprayed through the spray nozzle, and foreign substances or detergent liquid remaining on the surface are removed.

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

As described above, with the development and distribution 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 and 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 washed by immersion 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 into the immersion detergent, wherein the organic surfactant component has a characteristic that cannot be easily removed.

Therefore, when an actual water-flow immersion type dish washer and a rinse-wash spray type dish washer are disposed to sequentially wash and rinse the dish, a phenomenon in which some detergent solution remains on the surface of the dish 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 the rinse washing section in a horizontally deployed state, 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, and as a result, the rinsing washing water sprayed in the rinsing washing section is always sprayed on the plate at a constant angle, so that the rinsing washing water does not reach Cleaning blind areas are inevitably generated.

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

It is continuously pulled and moved in one direction, and includes a conveyor structure configured including a plate transfer belt 23 for arranging the plates T seated through the support fingers 24 in an upright state, respectively.

The plate transport belt 23 is composed of an annular assembly in which the supporting fingers 24 are connected in a chain link structure through a connecting pin 25, and the plate T through each supporting finger 24 is a plate transport belt ( 23) is supported by standing on the upper surface of the

And, as shown in FIG. 2, the support finger 24 is formed to stand on the chain link end 24a connected to the chain link structure through the connecting pin 25, and the chain link end 24a, so that the plate ( T) is composed of a molded body formed with a plate support end (24b) for supporting upright.

In this embodiment, the support fingers 24 are connected in a chain link structure in a matrix structure through the connecting pin 25 to form an annular assembly, and additionally chain pieces ( 26) so that the plate conveying belt 23 is assembled with the sprockets provided on the drive shaft 21 and the driven shaft 22 through the chain piece 26 to be pulled and moved in one direction by the drive shaft 21 rotating in one direction. are doing

On the other hand, in the present invention, as shown in FIGS. 1, 4 and 5, the plate transport belt 23 disposed on the movement path of the plate transport belt 23 and moved by pulling it in one direction is curved to guide the plate, It further includes a bending roller part 50 for changing the support angle of the plate (T) by rotating the support finger 24 for supporting the plate (T) in the front-rear direction by deforming the transfer belt (23) up and down to bend.

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, preferably the lifting support roller By disposing compression support rollers 52 downwardly supporting both upper sides of the plate conveying belt 23 bent in an arcuate shape by an elevating support roller 51 at the front and rear of 51, the bending roller part 50 ) The plate conveying belt 23 passing through 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 conveying section (CA) in which it is deformed and moved vertically.

Therefore, the plate transport belt 23 of the plate transport unit 20, which aligns the plates (T) to stand up by the bending roller unit 50 and moves in one direction, is bent by the bending roller unit 50 while 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 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 plate (T) seated on the plate conveying belt 23 is the standing angle that passes through the tunnel space part 10 through the bending roller part 50 is deformed, so that it is injected 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. will change the angle.

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

Here, the elastic interference member 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.

With this configuration, when the plates T are excessively tilted forward by the bending of the plate transport belt 23, the elastic interference member elastically interferes with the upper end of the inclined plate so that the support state of the support fingers 24 is changed. The phenomenon of deterioration is prevented, and as a result, the phenomenon of dismantling of the support state by the support fingers as the plate falls forward during the bending transfer process can be prevented.

As shown in FIG. 5 showing a comparative example, if an elastic interference member is not provided, the plate passing through the bending transfer section by the bending roller part intermittently tilts forward excessively, and falls forward due to inertia. However, if the elastic interference member is provided as shown in FIG. 4 , the phenomenon that the plate is tilted forward excessively is prevented, and thus the phenomenon that the plate is tilted forward can be prevented.

Therefore, the plates (T) that are arranged to stand on the plate conveying 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 formed bending support section CA, 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) They meet the rinsing water and the washing water sprayed through the spray nozzle unit 30 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 the 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 in this process, so that stable rinsing and washing of foreign substances remaining on the surface of each plate (T) can be achieved. 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, is 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.
