DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing system for dishes and the like, and a nozzle structure suitable for use in such a washing system.

[0002]

2. Description of the Related Art Various types of cleaning systems for dishes and the like have been developed and used in the past. One of these types is a tableware in which washing water is to be washed using a nozzle. Etc. to be sprayed. As a conventional example of using a nozzle as described above, there is a conventional example in which a nozzle is a flexible tube having a spiral coil wound around the outer periphery. In the conventional cleaning system, when the cleaning water is jetted from the nozzle, since the nozzle tube is flexible, the cleaning water is jetted over a wide area by the swiveling movement of the nozzle tip by the reaction force of the jetting, The aim is to improve the cleaning effect.

[0003]

In such a conventional nozzle structure, when the pressure of the washing water fed into the nozzle is relatively low, the desired swirling motion of the nozzle is exerted to achieve the desired cleaning. The effect can be obtained. However, if the pressure of the wash water pumped into the nozzle is significantly increased in order to obtain even higher wash power, the nozzle tube loses its flexibility due to the high pressure wash water flow therethrough and simply extends straight. It does not perform the movement of swirling the nozzle tip, but only jets the cleaning water straight. In this case, there is a problem that the cleaning water is intensively sprayed only at one location, and it is not possible to achieve a wide range of cleaning effect.

An object of the present invention is to provide a cleaning system for dishes and the like and a nozzle structure which can solve the problems of the prior art as described above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in more detail with reference to the accompanying drawings according to embodiments and examples of the present invention.

FIG. 1 schematically shows the configuration of a dishwashing system or the like as an embodiment of the present invention. In the washing system of this embodiment, a washing basket 2 containing a large number of dishes 1 to be washed is transported to a washing station 20 by a conveyor belt 12 hung on a pulley 11 driven by a motor 10. Above the washing station 20, a trumpet-like washing water horn 30 is provided. A washing water injection nozzle 40 is attached to the washing water horn 30 so as to extend downward along the central axis. A cleaning station 2 is provided around the open end of the cleaning water horn 30 facing the cleaning station 20.
An enclosure 50 is provided to limit the area of the wash water that is jetted to zero.

The upper end of the washing water horn 30 is
0 and suspended and supported. Although the detailed structure of the washing water injection nozzle 40 will be described later, the washing water injection nozzle 40 is connected to a washing water supply pipe 61 constituting a part of the washing water supply means. The cleaning water supply pipe 61 is laid along the support structure 60, and the other end is connected to a pump 63 for pumping the cleaning water through an electromagnetic valve 62. In this embodiment, the pump 6
The cleaning water pumped by 3 is water or hot water containing a detergent. Further, in this embodiment, an appropriate amount of air is mixed into the washing water pumped by the pump 63 from the air supply pipe 64.

In this embodiment, the conveyor belt 1
Of the motor 10 for driving the cleaning water supply pipe 6
A control circuit 65 is provided for controlling the operation of the electromagnetic valve 62 for controlling the pumping of the cleaning water to the cleaning water 1 by adjusting the timing. The control circuit 65 gives, for example, an operation start signal to the motor 10 to drive the conveyor belt 12 to transport the washing basket 2 containing the dishes 1 to be washed to the washing station 20, and thereafter , A stop signal to the motor 10 to feed the conveyor belt 1
2 is stopped, and control is performed so that the washing basket 2 stays at the washing station 20 for a predetermined time. Next, the control circuit 65 gives an open signal to the solenoid valve 62,
The electromagnetic valve 62 is opened, and the cleaning water is supplied to the cleaning water injection nozzle 40, and the cleaning water is injected from the cleaning water injection nozzle 40 to the cleaning basket 2 remaining at the cleaning station 20 for a predetermined time. To be able to Then, after the washing of the dishes 1 in the washing basket 2 is completed, the control circuit 65 gives a closing signal to the solenoid valve 62 to stop the supply of the washing water to the nozzle 40 and, at the same time, sends an operation signal to the motor 10. Then, the driving of the conveyor belt 12 is resumed, and the washing basket 2 containing the washed dishes 1 is moved to the washing station 2.
0 to the storage area and bring the washing basket containing the next utensils to be washed to the washing station.

Next, the washing water injection nozzle 40 according to the present invention
Will be described in detail with reference to FIG.
FIG. 2 is a longitudinal sectional view of a water injection nozzle used as the cleaning water injection nozzle 40 in the cleaning system of FIG. As shown in FIG. 2, the water injection nozzle includes a flexible tube 41 having a predetermined length formed of, for example, nylon or vinyl. At one end of the flexible tube 41, for example, a metal connection port member 42 for connecting to a water supply means such as the above-described cleaning water supply pipe 61 is inserted. Further, an attachment connection auxiliary member 43 is attached to the connection port member 42.
A communication hole 43 that communicates with a communication hole 42 </ b> A of the connection port member 42 with the flexible tube 41 is provided in the attachment connection auxiliary member 43.
A is formed. Further, the mounting connection auxiliary member 4
For example, this nozzle is attached to the outer periphery of one end of the cleaning horn 3.
A screw portion 43B for extending and extending along the center axis of the screw is formed, and a screw portion for screw connection to the cleaning water supply pipe 61 is formed on the outer periphery of the other end. 43C are formed.

On the outer periphery of the other end of the flexible tube 41, a water injection port defining member 44 is mounted to define a water injection port and reinforce the water injection port. The water outlet defining member 44 may be formed of a suitable plastic material. Further, on the outer periphery of the flexible tube 41, a cylindrical turning adjusting member 45 is mounted at a position slightly retreated from the water jet port defining member 44. This turning adjustment member 45
May also be formed of a suitable plastic material. For example, by changing the mounting position of the turning adjustment member 45, the range and speed of the turning motion of the water jet, which is the tip of the flexible tube 41, can be adjusted.

According to the present invention, the flexible tube 41
The spiral coil 46 is inserted along the inner peripheral wall inside. The spiral coil 46 may be formed of an elastic metal material having corrosion resistance to washing water or the like. The spiral coil 46 functions as an obstruction effect imparting unit that provides an obstruction effect imparting unit that obstructs the flow of water that is pumped through the flexible tube 41. In this embodiment, the spiral coil 46 constitutes the obstacle action providing means, but the present invention is not limited to this. For example, the obstacle action imparting means may be a ridge or a groove formed in a spiral shape along the inner peripheral wall of the flexible tube 41. The ridge or groove may be formed integrally when the flexible tube is formed, or may be provided as a separate insertion member.

Next, with particular reference to FIG. 3, the washing water injection nozzle 4 during the washing operation in the washing system of FIG.
The behavior of 0 will be described. FIG. 3 is an enlarged sectional view showing a portion related to the cleaning water injection nozzle 40 in the cleaning system of FIG. When the electromagnetic valve 62 is opened and the cleaning water pressure-fed through the cleaning water supply pipe 61 is introduced into the flexible tube 41 of the cleaning water injection nozzle 40, as shown in FIG. Due to the obstruction effect given to the washing water flow by the spiral coil 46 inserted along the inner peripheral wall of the flexible tube 41 and the flexibility of the flexible tube 41 itself, the flexible tube 4
The tip of the first member makes a revolving motion as shown by the arrow S. The radius of the swirling motion changes at random from moment to moment within the range inside the cleaning horn 30. This behavior has been confirmed experimentally, and the theoretical basis has not been elucidated at this time. However, it is likely that the flexible tube 41 bends as a hindrance effect given by the spiral coil 46 to the water flow flowing in the flexible tube 41, for example, a reaction force of the resistance to the water flow, and this bending causes the resistance to the water flow And the degree of curvature of the flexible tube 41 changes as a reaction to the change in the resistance. Further, it has been experimentally confirmed that the water jet nozzle according to the present invention exhibits the same behavior even when the pressure of the water flow flowing to the flexible tube 41 is largely changed.

Therefore, the washing water is sprayed from the spray port at the tip of the flexible tube 41 as shown by the symbol J,
The jet direction of the washing water is changed every moment within a range limited to the opening range of the washing horn 30. For this reason, the washing water is sprayed evenly on the tableware 1 stored in the washing basket 2 placed on the washing station 20, so that very effective washing is performed.

Although the water injection nozzle described in detail with reference to FIG. 2 was used as the cleaning water injection nozzle in the cleaning system in the above-described embodiment, the present invention is not limited to this. The water jet nozzle according to the present invention is effective not only for jetting the washing water but also for the purpose of, for example, uniformly spraying various liquids over a wide range.

[0021]

As described above, even if the pressure of the washing water or the like to be fed to the nozzle is changed, uniform spraying is performed over a wide range, so that effective washing can always be performed. Therefore, it is possible to freely perform control such as increasing the cleaning water pumping pressure to increase the cleaning power in accordance with the degree of contamination of the dishes and the like to be cleaned.

According to the structure of the water injection nozzle of the present invention, uniform injection of various fluids over a wide range can be performed in spite of the simple structure of only the flexible tube and the obstruction effect imparting means such as the spiral coil. Can be.
