Description

Cleaner and Rinse Supply Apparatus for Ware Washer

The present invention relates to a container washer, and more particularly, to wipe off foreign substances such as oil contained in a container by supplying a first appropriate amount of detergent in a washing tank, and to induce sterilization and drying by adding a second rinse. A detergent and rinse supply device for a container washer.

Generally, measuring cups are used to dispense detergent in the container washers. In this case, the user must continuously input after a certain time, not only to cause inconvenience to the user, but also to cause chemical damage due to careless handling.

Another method is a hydraulic method in which detergent is introduced by the hydraulic pressure at the site of use. However, in the hydraulic method, the dosage is not constant according to the change of the hydraulic pressure, and detergent is impossible at low pressure and frequent failures.

Alternatively, a general chemical pump may be used, but the equipment is expensive, a separate control system is required, and a large installation space is required. The amount of detergent is relatively convenient, but the error range is wide, making precise control difficult.

In addition, when the timer method is applied, it is possible to inject detergent only as the timer is set, and to reset the timer or adjust the water pressure according to the washing water. According to this, the detergent is introduced as much as the timer is set during the operation of the washing machine, but the cleaning effect is reduced because the detergent cannot be supplied properly according to the washing product, and it is difficult to improve the productivity because the timer adjustment and the water pressure adjustment should be continued according to the washing product. It uses analog time control device and D / C motor pump, and there is a disadvantage that proper amount of control is inaccurate when used for a long time.

Automatic container washer is 70-80% of the washing condition is determined by the quantitative supply of the detergent according to the washing water, the detergent supply device using the conventional method is not sanitary cleaning because it does not supply a constant detergent And a serious problem such as secondary sewage pollution.

Therefore, the object of the present invention is to solve the above problems, by supplying the first appropriate amount of detergent in the cleaning tank to wipe off foreign substances such as oil on the container, and by adding a second rinse to promote sterilization and drying To provide a detergent and rinse supply device for a container washer.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a configuration diagram showing the piping and wiring state by disassembling the main portion of the device according to the present invention,

The present invention relates to a container washer having a detergent container (12) and a rinse container (14) for supplying detergent and rinse to the washing tank (10), and a concentration sensor for detecting the concentration of the detergent on the washing tank (10). 35 is installed. The concentration sensor 35 for detergent detection is a part that is precisely controlled with a metering pump to be described later, and is essential to maximize the washing effect by narrowing the error range as much as possible. The concentration sensor 35 is a kind of chemical sensor and outputs an analog signal according to the concentration change of the detergent to be detected. This can be seen as using the principle of the moisture sensor used in the food processor.

In addition, according to the present invention, each of the quantitative feeder 20 which is driven independently and quantitatively transfers the detergent or the rinse is mounted on the pipe from the detergent container 12 and the rinse container 14 to the washing tank 10. One side of the metering feeder 20 is connected to the pipe flowing from the detergent container 12 and transferred to the washing tank 10, and the other side is connected to the pipe flowing from the rinse tank 14 and transferred to the washing tank 10. . The metering feeder 20 is preferably installed at a position close to the washing tank 10 to minimize the length of the pipe.

In addition, the controller 30 according to the present invention receives the signal of the concentration sensor 35 as the input unit 32, compares with the reference value preset in the microcomputer 31, and the drive unit 33 in accordance with the lack of the comparison value Through the algorithm to control the output to the metering feeder 20 through. The microcomputer 31 includes a microprocessor and memories such as EPROM and RAM. The input unit 32 includes an A / D converter for converting a signal of the concentration sensor 35 into digital data. The driving unit 33 includes a relay or a power transistor for controlling the motor power of the metering supply 20.

Although not shown, the controller 30 is configured to be able to use any voltage, in particular, it is possible to apply to the washing machine driven by a dual power source by configuring a dual voltage of 24V-240V, 50V-60V range. Thermocouple temperature compensation ensures that the detergent is released throughout the entire temperature range.

Figure 2 is a perspective view showing the internal configuration by disassembling the metering feeder according to the present invention.

The metering feeder 20 of the present invention has a pair of gear motor 22 and the metering pump 24 on the integral housing 21 to face. Covers 23 are respectively mounted on both sides of the housing 21, and each cover 23 is equipped with a gear motor 22 and a metering pump 24. This is a DC motor pump to quantitatively dispense detergent and rinse with a minimum error range when controlled by the program of the controller 30.

At this time, the specification of the metering feeder 20 and the pipe connected thereto considers chemical resistance so that both liquid or powdery detergents can be used as well as detergents as well as chemicals.

3 is a graph showing a control principle according to the present invention, Figure 4 is a flowchart showing the main algorithm of the controller according to the present invention.

When the processing of the program according to the present invention is started in the controller 30, the controller receives the appropriate temperature O.P and then the concentration sensor 35. In the next step, the two motors are compared to drive the gear motor 22 of the metering feeder 20 at the lowest concentration (L.P), and the gear motor 22 of the metering feeder 20 is stopped at the highest concentration (H.P).

In this case, the gear motor 22 for the detergent transfer is controlled at a constant speed, while the gear motor 22 for the rinse transfer may be freely controlled. By adjusting the speed of the gear motor 22 and the quantitative pump 24 for rinsing, an appropriate rinse can be added to maintain optimal sterilization and drying conditions. Detergent concentration can be adjusted by selecting the range of 0% -100%.

In addition, the controller 30 receives the concentration reference value of the detergent according to the type of the object to be washed and changed through the dip switch 34. Appropriate control is performed by adjusting the dip switch 34 according to the type, water quality, and wash of the washer. As described above, the rinse adjusts the rotational speed of the motor according to the required amount at 0 to set a desired input amount, and the speed is designed so that the rinsing water can be supplied normally up to about 3 Kg / cm 2. Detergents to be metered in have a detergent content of 0 at the initial dose and reach H.P. At this time, the interval between H.P and L.P is preferably set.

In the method of measuring H.P and L.P according to detergent input at the development and design stage, a device or a reagent capable of measuring the amount of detergent diluted in the washing tank 10 is required. After preparing the washing machine to be tested as a standard model, the metering feeder 20 is operated, and after the detergent is completely put into the detergent pipe, the metering feeder 20 is stopped. Then, the metering feeder 20 is restarted, and after the detergent is completely added, the washing machine is stopped and the amount of detergent is measured with the reagent. The measured value is the highest concentration (H.P). Next, after the machine is cleaned and rinsed, the machine is stopped and the amount of detergent is measured when the detergent is refilled. The measured value is the lowest concentration (L.P). It is desirable to repeat the process several times in this way to obtain an average value.

On the other hand, there are two types of reagents: a detection reagent and a reducing reagent. When two drops of a predetermined detection reagent are added, the reagent turns purple. Drop the prescribed reducing reagent by 1 drop and shake the container sufficiently to check the amount of detergent according to the number of drops until it is reduced to colorless.

At this time, the controller 30 of the present invention operates an alarm when the detergent concentration in the washing tank 10 does not reach the reference value within a predetermined time. In the above-described conventional water pressure method, timer method, etc., it is necessary to take irregular detergent supply, but by applying the device of the present invention, it is possible to freely adjust the detergent and rinse concentration while maintaining a fixed supply amount, as well as displaying a lamp and the like during normal operation. In case of automatic supply error Perform.

More specifically, alarms and lamps flash when the detergent runs out and at the same time the cleaning process stops naturally. The alarm size can be adjusted to suit the working environment. Hardware processing using a separate switch or software processing using a program adjusts the alarm delay time until the detergent reaches the set reference value. After the alarm is triggered, switch off the power and start the program again to restore the detergent supply.

In operation, first, the washing machine, the washing water, the water quality is measured by adjusting the dip switch 34 so that the appropriate amount of detergent concentration is set, and then the washing tank 10 is filled with water and the washing machine is operated when the proper temperature is reached. Thereafter, the metering feeder 20 is operated according to a predetermined program and a series of washing operations are completed.

Conventional detergent supply device can not expect the washing effect and productivity improvement and sanitary treatment due to near manual work, but the device of the present invention can be maximized productivity and sanitary treatment because it is processed by a fully automated concept. As food poisoning accidents of group meals are frequent, hygiene management of tableware is important.

The domestic detergent dosing device market is expected to be over 50 billion won per year. Currently, the automatic detergent supply device is more than 90% dependent on foreign imports. Therefore, it is expected to have a great influence on import substitution effect and securing external competitiveness.

The device of the present invention adopts this technology in an automatic dishwasher, but can be widely used in an industrial automatic washing machine, an ultrasonic component washing machine, an industrial washing machine, etc. using water-soluble detergent. In addition, the quantitative injection of the boiler cleansing agent, the automatic quantitative injection of various chemicals in the wastewater purification facility, the water treatment facility, and also can be applied to various experimental equipment.

In addition, it is possible to apply to a machine, a facility, a place where it is necessary to react according to the concentration of solute dissolved in a solvent and maintain a constant concentration.

According to the above configuration and operation, the present invention supplies the first appropriate amount of detergent in the cleaning tank to wipe off foreign substances such as oil on the container, and adds a second rinse to promote sterilization and drying to improve cleaning power and environment. It is effective in preventing contamination.

It is apparent to those skilled in the art that the present invention is not limited to the embodiments described, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or modifications will have to belong to the utility model registration claims of the present invention.
