Description

One-stop cup automatic cleaning device}

This is about a cleaning and storage device that automatically cleans, dries, sterilizes, and stores cups.

Cups are generally used as containers for drinking water or beverages, and are made of various materials such as glass, plastic, and metal. These cups are widely used in vending machines and restaurants, and after use, the cups are washed manually by managers. However, there is a limit to washing large quantities, so they are currently washed in a dishwasher.

However, since the dishwasher is not a device specifically for washing cups, it is not only inconvenient to use for washing cups, but also has a high risk of being damaged by collision with dishes. In addition, despite the fact that cups do not often have dirty or difficult-to-clean surfaces on their surfaces, conventional dishwashers wash cups to the same extent as dishes, which not only wastes a lot of water but also wastes a lot of time. There was a problem with power being wasted.

To solve this problem, Korea Patent No. 10-0881712 "Cup Washer" was invented to greatly improve the cleanliness and usability of cups by sterilizing and washing used cups and storing them. However, after washing, drying, and sterilizing at a temperature unsuitable for the material of the cup, the cup became deformed or damaged and became unusable. Even if the manager directly sets the temperature and operating time, it is inconvenient to manually check and set the temperature appropriate for the material. It was raw. Also, because the cups were not completely sterilized at the appropriate temperature and time, there was a risk that bacteria or viruses that cause food poisoning and disease could be spread through the cups. As the device was equipped to move the cups one by one inside the device and go through a cleaning and drying process, As the size of the device grew, there was a problem that space for installation had to be considered.

Republic of Korea Patent Publication No. 10-0881712

The purpose of the present invention is to automatically determine the material of the cup placed in the device, set appropriate washing, drying, and sterilization temperatures and operating times according to the material of the cup, and perform the washing, drying, and sterilization of the cup sequentially. The goal is to provide a one-stop automatic cleaning and storage device that is stored inside and can be used as a one-stop from cleaning to storage using a single device.

The washing and storage device of the present invention includes a main body in which a plurality of cups are arranged and stored; A detection unit installed inside the main body and irradiating a laser to the cup to determine whether it is metal, glass, or plastic; a washing unit installed on the inner wall of the main body unit and spraying washing water into the cup at a preset intensity and temperature according to the determination result of the sensing unit; a drying unit installed inside the main body unit and spraying hot air onto the cup at a preset intensity and temperature according to the determination result of the sensing unit; and a sterilizing unit installed inside the main body unit and irradiating an ultraviolet lamp toward the cup at a preset operating time according to the determination result of the sensing unit. The cleaning unit, drying unit, and sterilizing unit are sequentially executed. .

It can be improved. In addition, since the cleaning, drying, and sterilizing units are sequentially performed in one device, space usage can be minimized, unlike existing devices where several devices exist separately.

In addition, by automatically classifying the material of the cup as metal, glass, or plastic based on laser transmission and diffuse reflection, the user can automatically distinguish the cup material without any separate settings and set a customized sterilization environment accordingly. Convenience for administrators can be improved.

In addition, by comparing and reading the appearance of the cup, it is possible to automatically detect foreign substances, damage, or distorted state of the cup. When an abnormality in the cup is detected, it can notify the manager, greatly improving the convenience of cup management. .

In addition, individual identification numbers are assigned to multiple cups placed inside the device, and the identification number and current image of the cup in which an abnormality is detected are sent together to the administrator terminal, so that the administrator can use the identification number to immediately locate the cup and create a new one. It can be replaced with

In addition, based on fine dust, food poisoning, and infectious disease information received from external data, sterilization can be controlled by adjusting the hot air intensity and temperature of the drying section and the ultraviolet lamp irradiation time of the sterilizing section, and the manager can provide news information or related news. Even if it is not possible to confirm, information about this can be reflected in advance.

The one-stop automatic cleaning and storage device that can be used as a one-stop from cleaning to storage using a single cleaning and storage device will be briefly abbreviated as 'cleaning and storage device.'

1 is a diagram showing the internal configuration of the one-stop automatic cleaning and storage device of the present invention. Referring to FIG. 1, the washing and storage device of this embodiment includes a main body unit 100, a sensing unit 200, a cleaning unit 300, a drying unit 400, a sterilizing unit 500, an identification unit 600, and a photographing unit. It may include a unit 700, a storage unit 800, and a control unit 900. The cleaning and storage device with this configuration can clean, dry, sterilize, and store the cup in one stop with one device. It reads the material of the cup and cleans, dries, sterilizes, sterilizes, and operates at a temperature and operating time within the range that does not cause damage. The sterilization function can be improved by controlling.

The main body 100 has a rectangular box-shaped interior in which a plurality of cups are stored upside down in a single layer so as not to overlap each other, and an installation space is provided so that other components can be installed inside. In particular, the main body 100 stores a plurality of identical cups made of one of metal, glass, and plastic inside, so that washing, drying, and sterilization are performed under appropriate conditions. In detail, the main body 100 includes a main body 110 whose front side of the rectangular box is opened and closed by a door, a shelf 120 and a main body 110 that are installed in layers spaced apart inside the main body 110 and on which a cup is placed. ) It is installed on the inner floor and includes a water catcher (130) that stores the washing water that falls during washing.

The main body 110 has a front surface made of glass or a display so that the inside can be seen through a door that opens and closes in the front, so that the working status can be checked when the cup stored inside is washed, dried, and sterilized. In addition, the main body 110 is equipped to allow touch input through a display formed on the front, so that the administrator can arbitrarily set or change the set temperature and operating time during cleaning, drying, and sterilization. Through this, the main body 110 allows the manager to easily check and control the operation of the cleaning and storage device, thereby improving the manager's workability and convenience.

The shelf support 120 is spaced vertically within the main body 110 so that the shelf support can be fixed left and right symmetrically, and is installed to rest on the upper part of the shelf support. At this time, the shelf 120 is equipped with a plurality of anti-slip protrusions regularly formed on the upper surface or a fixing protrusion for fixing the cup is inserted into the cup. As a result, cups placed face down on the upper surface of the shelf stand 120 do not move due to pressure when washing water is sprayed, so that a plurality of cups can be safely washed without colliding with each other. In addition, the shelf stand 120 is made of a mesh network, so that when washing the cup, the washing water flows downward, so that the water collects in the water pan 130 and is discharged to the outside through the discharge pipe.

In detail, the water pan 130 is formed concavely in a square shape to correspond to the lower surface of the main body 110 and is inclined toward the outlet. At this time, a water level sensor is installed on the inner side of the water pan 130 to measure the amount of stored washing water. In addition, the water pan 130 has an outlet formed on one lower side and is connected to the outside through a discharge pipe, and when the water level measurement sensor detects that the standard water level has been exceeded, the outlet is automatically opened. In addition, the water pan 130 allows the washing water to be discharged to the outside through the discharge pipe, thereby preventing an accident where the washing water overflows from the water pan 130.

The detection unit 200 is configured to irradiate a laser to the cup to determine whether it is metal, glass, or plastic. This detection unit 200 irradiates a laser to one of the plurality of cups to determine the material of the cup, and the control unit 900 can determine whether the laser is transmitted or reflected. First, the sensing unit 200 is determined to be metal when the laser is non-transmitted and reflected, is determined to be glass when the laser is transmitted, and is determined to be plastic when the laser is diffusely reflected. In detail, diffuse reflection refers to light reflection that is reflected in multiple directions when light entering a surface is reflected.

This detection unit 200 can identify transparent objects by mounting a photoelectric sensor on the back of the cup where the laser is irradiated, and detecting changes in distance and brightness of light. In addition, metal proximity sensors can be used to classify metals and non-metals, and sound sensors can be used to classify plastics and glass. At this time, because the sound of the glass cup is relatively louder than the sound of the plastic cup, if the sound is between 300 and less than 400, it is judged as a plastic cup, and if it is over 400, it is judged as a glass cup.

The washing unit 300 is configured to spray washing water into a plurality of cups displayed within the main body 100 to clean them. Such a washing unit 300 can be arranged left and right on each floor where cups are displayed, and is equipped with a spray nozzle through which washing water is sprayed. At this time, the spray nozzle is formed so that the washing water is discharged in a straight line, or is rotated to discharge in a spiral shape and spreads over a wide area, and the spray angle can be changed to improve workability during washing. The washing unit 300 sprays washing water mixed with detergent used for washing and water, and then sprays water used for rinsing before drying, allowing drying work to be performed with the detergent on the cup washed away.

In detail, the cleaning unit 300 automatically sets the set temperature and operating time according to the material of the cup read by the sensing unit 200. For glass cups, the washing temperature is set to 50-60℃, the rinsing temperature is set to 65-75℃, and the operating time is set to 30-40 minutes. And in the case of stainless steel cups, the washing temperature is set to 65-75℃, the rinsing temperature is set to 70-80℃, and the operating time is set to 20-30 minutes. For plastic cups, the washing temperature is set to 55-65℃, the rinsing temperature is set to 55-65℃, and the operating time is set to 30-40 minutes.

The drying unit 400 is configured to spray hot air onto a plurality of cups cleaned within the main body 100 to dry them. This drying unit 400 may have a hot air blower installed in the lower part of the main body 100, and hot air rises from the lower part of the main body 100 to the upper part, passing through the mesh of the shelf 120 and displaying cups. can all be dried. In addition, the drying unit 400 has heat blowers installed on both sides of the lower part of the main body 100, thereby shortening the drying time and increasing drying efficiency. In addition, the drying unit 400 is operated immediately after the rinsing operation in the washing unit 300 is completed, thereby shortening the working time.

In detail, the drying unit 400 automatically sets the set temperature and operating time according to the material of the cup read by the sensing unit 200. For glass cups, the drying temperature is set at 65-75℃ and the operating time is 20-30 minutes. As an example of metal, for stainless steel cups, the drying temperature is set to 85-90℃ and the operating time is 15-20 minutes, and for plastic cups, the drying temperature is set to 55-65℃ and the operating time is 20-30 minutes. This type of drying unit 400 is set higher than the washing temperature and dries quickly in a short period of time. Not only can it prevent water marks from forming, but it can also achieve a sterilizing effect on the cup by exposing it to ultraviolet rays in a completely dried state.

The sterilizing unit 500 is configured to sterilize the cup by irradiating ultraviolet rays toward the cup using an ultraviolet lamp installed on the upper surface or inner wall of the main body 100. Such a sterilizing unit 500 emits UV-C wavelengths and has a sterilizing effect on various bacteria, and sterilizing and disinfecting effects can be expected. In particular, the sterilizing unit 500 does not transmit ultraviolet rays through metal or plastic cups, so the sterilizing effect is achieved only when it is directed directly to the area requiring sterilization. Therefore, when attempting to sterilize a cup made of that material, the inner surface of the cup must be exposed to ultraviolet rays. make it possible

To this end, the sterilizing unit 500 sterilizes the cup in an overturned state, and then the manager directly rotates the cup to the correct position so that the inner surface of the cup is exposed to ultraviolet rays by the ultraviolet ray lamp at the top. In addition, in the sterilizing unit 500, the ultraviolet sterilizing effect is inversely proportional to humidity, so if the cup is exposed to ultraviolet rays without drying, the ultraviolet sterilizing effect cannot be expected, and the recommended sterilizing time for the sterilizing effect is maintained at more than 40 minutes when using 10W. shall.

The identification unit 600 is configured to identify the cups by assigning individual identification numbers to each position of the plurality of cups arranged in each layer in the main body 100. This identification unit 600 helps the manager easily identify and find the location of the cup using the cup's identification number, and has the effect of shortening the manager's work time. The identification unit 600 can be expressed as

The photographing unit 700 is configured to photograph the exterior of a plurality of cups after the operation of the sterilizing unit 500 is completed and store the current image 710. This photographing unit 700 can be installed on the inner upper and rear surfaces of the main body 100, and can store the current image 710 by simultaneously photographing a plurality of cups or separately photographing the exterior for each identification number. Additionally, when taking individual shots, the photographing unit 700 rotates and moves to the corresponding position of the cup by an object detection sensor and takes pictures only when the cup is placed, and does not recognize empty spots, thereby preventing unnecessary image taking.

The storage unit 800 stores the initial image 810 for comparison with the current image 710 of the cup. At this time, the storage unit 800 preferably stores the first image 810 for each cup material, and the first image 810 corresponding to the material of the cup determined by the detection unit 200 is transmitted to the control unit 900. It can be. This storage unit 800 stores the initial image 810 so that it can detect foreign substances in the cleaned cup, a damaged cup, or a distorted cup that has been dented.

The control unit 900 controls the operation of each component of the cleaning and storage device to clean, dry, sterilize, and store the cup. The control unit 900 determines the material in the detection unit 200 according to whether the laser is transmitted or not and whether there is diffuse reflection. At this time, the control unit 900 may determine that the laser is metal if non-transmission is detected by the detection unit 200, may be judged to be glass if the laser transmission is detected, and may be judged to be plastic if diffuse reflection is detected.

In particular, the control unit 900 compares and reads the captured current image 710 and the first image 810 to detect an abnormality in the cup and transmits an abnormality detection notification to the manager terminal 10. Unlike the initial image 810, the control unit 900 may detect an abnormality in the cup in the current image 710 due to residual foreign substances in the cup or a damaged or distorted state. At this time, the control unit 900 transmits the cup's identification number 610, current image 710, and abnormality detection notification 910 to the manager terminal 10 so that the manager can immediately check it.

Here, the manager terminal 10 can be wirelessly connected to the washing and storage device using an app, and the manager checks the manager terminal 10 by the abnormality detection notification 910 and then checks the current image 710 to place the cup. You can decide whether to replace it. If the manager determines that the cup needs to be replaced, the manager presses the replacement button on the manager terminal 10 and replaces the cup corresponding to the identification number 610 with a new one. On the other hand, if the manager determines that replacement of the cup is unnecessary, he or she presses the no-replacement button on the manager terminal 10 and stores the cup so that it can continue to be used.

At this time, the control unit 900 learns feedback by matching the current image 710 with the current image 710 to determine whether the current image 710 needs to be replaced, and when a similar image determined not to need replacement is confirmed, the administrator terminal 10 You can prevent the abnormality detection notification (910) from being transmitted. As a result, the control unit 900 can increase the accuracy of cup abnormality detection by preventing unnecessary abnormality detection notifications 910 from being transmitted to the manager terminal 10, and improve the manager's work efficiency.

In addition, the control unit 900 is connected to external data to receive information on fine dust, food poisoning, and infectious diseases, and controls the intensity and temperature of the hot air in the drying unit 400 to block viruses that can cause various diseases from the outside. The cup is sterilized with high-temperature hot air so that the user can use the cup safely. At this time, the control unit 900 receives information about various viruses and disease-causing information from organizations that provide information (Korea Disease Control and Prevention Agency, Korea Meteorological Administration, News, etc.) and outputs the intensity of the hot air at a higher level than the intensity of the hot air that is actually used. The temperature of the hot air is controlled to sterilize the cup at a high temperature of 90℃.
