Description

Unpowered rotary injecting device}

The present invention relates to a spray device, and more specifically, to a non-powered rotary spray device that can clean cups or containers with strong spray force.

Cups are used to drink water or beverages. If a small amount is used at home, a cup with a handle is often used. Since there are not many dishes to be washed, it is not a big problem, but it is used in restaurants and meal facilities where a large amount of water is used (e.g., schools). , military bases, hospitals, cafeterias, etc.), it is inevitable that difficulties will arise in cleaning a large number of cups.

Accordingly, many dedicated washing machines that automatically clean only cups have been developed and used, and the most commonly used cups have a simple shape with a smaller cross section toward the bottom and are made of stainless steel or synthetic resin. At this time, it is natural to spray water for cleaning, but in order to ensure that the sprayed water drains quickly, in most cup cleaning devices, the cleaning process is performed by moving the cup on its side, and then drying and sterilization are performed in the same condition. It was common.

However, in the process of moving the cup on its side and going through the cleaning, drying, and sterilization process, the surface in contact with the floor may be partially cleaned or sterilized insufficiently even if the cup rolls, and after washing, the inner surface of the cup may be turned downward. Even if it is tilted, there is a risk of foreign substances entering during the drying process by blowing water in a state where the water is not completely drained.

To solve these problems of conventional cups, containers, or dishwashers, pumps and spray nozzles were used. In other words, it is a method of simply spraying high-pressure cleaning water using a pump. However, this method had the inconvenience of requiring a pump and power wiring. Additionally, to increase cleaning power, a pulsed water stream was sprayed or a rotating nozzle was used. However, these conventional injection devices used solenoid valves or actuators (e.g., eccentric motors, etc.) to form pulses, which inevitably entailed the inconvenience of wiring, noise, and vibration. Additionally, rotary nozzles had the disadvantage of sanitary issues and reduced durability due to corrosion of the ball bearings that support rotation.

In addition, the side water flow unit 150 includes a water flow inlet 152 formed in the axial direction; and a side outlet 154, one end of which is connected to the water inlet 152, and the other end of which is formed in a direction inclined to the inner surface of the main body 130.

In addition, a plurality of side discharge ports 154 are arranged at an equal angle, and the inclined direction is at least one of the radial direction, the inclined direction, and the axial direction.

Additionally, the impeller unit 200 includes an impeller 210 that is provided at the other end of the impeller unit 200 and rotates by a vortex.

Configuration of the Example

Hereinafter, the configuration of the preferred embodiment will be described in detail with reference to the attached drawings. Figure 1 is a schematic configuration diagram of a cup washing machine equipped with a non-powered rotary spray device according to an embodiment of the present invention. As shown in FIG. 1, the raw water pipe 50 may be a water supply facility. The sterilizing water generator 30 receives raw water from the raw water pipe 50 and generates electrolytic sterilizing water 350 using a diaphragm-less electrolysis method. The generated sterilizing water 350 flows into the spray device 100 through the pipe 10. A cleaned cup 60 is placed on top of the spray device 100.

Figure 2 is a perspective view of the non-powered rotary injection device 100 in Figure 1. As shown in FIG. 2, the injection device 100 is arranged vertically, the pulsation device 300 is located at the bottom, and the main body 130 is assembled on the top of the pulsation device 300.

The pulsation device 300 causes a pulsation phenomenon while mixing the sterilizing water 250 and the gas (e.g., air, carbon dioxide, etc.) 270. SURGING is a phenomenon in which the pressure and discharge amount of the liquid periodically fluctuate in the flow of liquid without a free water surface in the pipe, resulting in periodic vibration in the pipe. There are various causes of such a pulsation phenomenon, but it is known to occur when the discharge pipe of the pipe is long and there is a part where air, such as an air pocket, is present inside the pipe. Meanwhile, the pulsation phenomenon is a factor that hinders the smooth flow of fluid within the pipe. In general, methods to prevent the pulsation phenomenon, such as removing air in the pipe or adjusting the cross-sectional area, flow rate, and flow rate of the pipe, are being studied. The invention seeks to propose a method to improve the cleaning and cleaning effect of the cup through the vibration inside the pipe generated by the pulsation phenomenon and the amount of impact applied to the wall inside the pipe.

A pipe 10 is connected to the lower part of the pulsation device 300, and a gas inlet 310 and a check valve 320 for backflow prevention are located on the side.

The main body 130 is a hollow hexagonal metal body, and the nozzle 110 is exposed at the top. A pair of side holes 140 are formed on both sides of the main body 130, and the pulsating washing water 360 is branched. The branched washing water 360 is used to clean the outer surface of the cup 60.

Figure 3 is a cross-sectional view when the impeller part 200 of the non-powered rotary injection device 100 shown in Figure 2 is at the upper point, and Figure 4 is a cross-sectional view of the impeller part (200) of the non-powered rotary injection device 100 shown in Figure 2. This is a cross-sectional view when 200) is at the lower point.

As shown in Figures 3 and 4, the pulsation device 300 has a hollow shape, and a sterilizing water inlet 380 is formed at the bottom through which sterilizing water 350 flows in the axial direction, and on the side, a gas (gas) is formed in the radial direction. A gas inlet 310 through which 370 flows in and a check valve 320 are formed.

The mixing sphere 340 has a hollow cone-cylinder combination shape. In the mixing port 340, the sterilizing water 350 flowing in the axial direction and the gas 370 in the circumferential direction are mixed to cause a pulsation phenomenon.

A pair of side holes 140 are formed to be symmetrical on the side of the main body 130 and branch the washing water 160 to the side. The side washing unit 160 is fastened to the side hole 140 and sprays the branched washing water 160 onto the outer surface of the cup 60. To this end, the side washing unit 160 may include curved pipes or flexible pipes and nozzles.

As shown in FIGS. 6A and 6B, the side water flow unit 150 is built into the bottom of the main body 130, sprays the cleaning water 360 to the inner surface of the main body 130 to generate a vortex, and is made of synthetic resin. It is a resin material.

A water flow inlet 152 formed in the axial direction is formed on the lower surface of the side water flow unit 150, through which the washing water 360 flows. One end of the side discharge port 154 is connected to the water flow inlet 152, and the other end is formed in an inclined direction with the inner surface of the main body 130. Two to four side discharge ports (154) are arranged at an equal angle relative to the axis, and are inclined in the radial direction in the range of 10° to 30° and axially in the range of 70° to 85° (5° to 20° for the horizontal plane). °) and is formed to slope upward. The radial inclination of the side discharge port 154 causes the cleaning water 360 to create a vortex, and the axial inclination causes the vortex to move upward. Optionally, the side discharge port 154 may be formed to have a gradually smaller diameter along the side discharge port 154 (e.g., about 4 to 6 mm), thereby creating a nozzle effect and increasing the rotational speed of the vortex.

FIG. 5 is an operation state diagram illustrating a state in which the impeller unit 200 of FIG. 3 cleans the cup 60. As shown in FIG. 5, a plurality of impellers 210 are formed at the lower part of the impeller unit 200, a nozzle 110 is located at the upper part, and the washing water 360 inside can rise. A flow path 230 is formed.

The impeller unit 200 rotates at high speed due to the vortex of the cleaning water 360, and is moved up and down and vibrates due to the pulsation phenomenon of the cleaning water 360 and the repulsive force of the first and second permanent magnets 170 and 180. do.

Additionally, the lower part of the washing water flow path 230 is open in the central area of the impeller 210. Washing water 360 also flows in through the lower part of the open washing water flow path 230.

The nozzle 110 is formed at the top of the impeller 200 to communicate with the washing water flow path 230 and is exposed to the outside of the top of the main body 130. The nozzle 110 is shaped like a single slit 120 to form a powerful fan-shaped water stream 70. The nozzle 110 continuously sprays the cleaning water 360 while reciprocating between the upper point as shown in FIG. 3 and the lower point as shown in FIG. 4 (e.g., 2 to 4 cm).

As shown in Figure 5, the fan-shaped water flow 70 has an angle in the range of approximately 150° to 170° and is very thin. The cup 60 to be cleaned is placed upside down on the upper part of the nozzle 110.

The second permanent magnet 180 is provided in an annular shape on the rotation center of the impeller unit 200. As shown in FIG. 5, the second permanent magnet 180 is located in an embedded form at the top of the impeller 210.

The first permanent magnet 170 has the same shape as the second permanent magnet 180, and is provided to face the second permanent magnet 180 inside the main body 130. The first permanent magnet 170 and the second permanent magnet 180 are oriented with their N poles facing each other or their S poles facing each other so that mutual repulsion occurs. The first and second permanent magnets 170 and 180 may be non-contact magnetic bearings (or air bearings).

Operation of the Embodiment

Hereinafter, the operation of the preferred embodiment will be described in detail with reference to the attached drawings. First, the sterilizing water 350 flowing into the sterilizing water inlet 380 is mixed with the gas 370 at the mixing port 340, contains fine bubbles (microbubbles), and vibrates due to a pulsation phenomenon.

A portion of the generated washing water 360 is diverted to the side washing part 160 and used to wash the outer surface of the cup 60.

The washing water 360 flowing into the water inlet 152 of the side water flow unit 150 is discharged in the radial direction through the side discharge port 154. At this time, a vortex is formed around and above the side water flow unit 150.

The generated vortex rises inside the main body 130 and rotates the impeller 210 at high speed. Due to the rotation of the impeller 210, the nozzle 110 also rotates. At this time, the washing water 360 passing through the lower part of the washing water flow path 230 forms a fan-shaped water flow 70 through the slit 120 of the nozzle 110 and collides with the inner surface of the cup 60.

Due to the turbulent vortex of the washing water 360, the impeller unit 200 does not maintain a constant position but moves back and forth and vibrates. At this time, the first and second permanent magnets 170 and 180 exert mutual repulsive force so that the impeller unit 200 continuously moves back and forth.

Figure 7a is an operation state diagram showing a state in which a conventional nozzle 85 cleans the cup 60, and Figure 7b is an operation state diagram showing a state in which a spray device according to the present invention cleans the cup 60. As shown in FIG. 7A, in the conventional nozzle 85, a spherical water stream 80 is formed to clean the inner surface of the cup 60. Therefore, sufficient water flow did not collide with the bottom or corner of the cup 60, so complete cleaning was not achieved.

On the other hand, as shown in Figure 7b, a fan-shaped water stream 70 is formed in the nozzle 110 of the present invention. Since the volume of the fan-shaped water stream (70) is smaller than that of the spherical water stream (80), the flow speed becomes faster. In addition, the fan-shaped water stream 70 of the present invention forms a spiral trajectory due to the rotation and vertical movement of the nozzle 110. The fan-shaped water stream 70 with a spiral trajectory cleans the bottom and corners of the inside of the cup 60 with a powerful water stream. Moreover, since microbubbles generated by the pulsating device 300 are included in the washing water 360, the washing power is further increased when the microbubbles burst while colliding with the cup.
