DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultraviolet disinfection system for a vending machine that prepares, manufactures and sells food, drink, ice, hot water, and the like using purified water, and more particularly, to miniaturize the system and improve water safety. The present invention relates to an ultraviolet disinfection system for a vending machine which is high, clean and sanitary.

[0002]

2. Description of the Related Art Conventionally, in a cup type vending machine,
Water was passed through a filter or an adsorbent such as activated carbon to purify the water. In addition, for sterilization of water, chemical treatment with chlorine or the like, heating, or physical treatment with ultraviolet light or the like has been performed.

[0003]

In many ordinary cup-type vending machines, an activated carbon filter is provided. In this case, it is advantageous to remove chlorine odor by adsorbing chlorine etc. in tap water on activated carbon, but since water from which chlorine has been removed has a very weak bactericidal activity, bacteria grow in activated carbon and purification is performed. Bacteria are often contained in waste water in large quantities. Therefore, it is necessary to frequently replace the activated carbon filter.

[0004] In the case of a cup-type vending machine having a device for adding a disinfectant such as chlorine, the disinfectant is again contained after removing the chlorine and the like by the activated carbon filter, which is not efficient. In addition, there is a risk that health may be impaired by the disinfectant.

[0005] In the case of a cup-type vending machine having a heat sterilizer, if heat sterilization and activated carbon adsorption are performed in the same container, the adsorption power of activated carbon is reduced, so that adsorption sterilization can be performed in one container. Must be cleaned and sterilized in separate containers. Therefore, there is a limit to miniaturization of the device. Further, since the heat-sterilized water is not immediately cooled, it may further include a cooling device, but this takes time and has a problem in efficiency.

[0006] In the case of a conventional apparatus which purifies with an activated carbon filter and sterilizes with ultraviolet rays, it often still contains slightly surviving bacteria. This is because there is a problem in the sterilization method and the structure of the device.

[0007] Activated carbon water purification and ultraviolet sterilization are usually performed in separate containers in many cases.
Japanese Patent Application Laid-Open No. 09-09090 and Japanese Patent Application Laid-Open No. H10-180251), which makes it difficult to reduce the size of the device. There are quite a few cases in which activated carbon water purification and ultraviolet sterilization are performed in the same container (Japanese Patent Laid-Open Nos. 5-277494 and 10-2).
No. 16705, JP-A-11-9993), these are those in which activated carbon is irradiated with ultraviolet rays, and the adsorbed substance adsorbed on activated carbon by the ultraviolet rays is desorbed,
Because the adsorption power decreases due to the deterioration (oxidation) of the activated carbon,
Purification action is not sufficiently exhibited.

[0008] In addition, a usual cup-type vending machine often stores purified and sterilized water in a tank, but the purified water has a weak sterilizing power. Proliferate in water and water is often unsafe.

In addition, the periphery of the supply unit having a nozzle for pouring beverages or foods, ice, hot water, etc. of the cup-type vending machine and a receiving unit for receiving the cup (where the cup comes out) is in contact with the outside air. In many cases, floating bacteria adhere, oxygen is sufficiently supplied, and water droplets of drinking water scatter around the supply portion, and sugars and the like in the drinking water often adhere. In this case, there is a problem in hygiene because the environment is excellent for bacteria to grow. In order to prevent the propagation of this bacterium, a chemical means such as a disinfectant is sometimes used (Japanese Patent Laid-Open No. 5-2 / 1993).
However, there is a problem in view of simplicity of handling and health safety.

[0010] It is an object of the present invention to provide a clean and sanitary UV disinfection system for vending machines, which makes the system smaller, increases water safety and is clean.

Another object of the present invention is to provide an ultraviolet sterilizing system for a vending machine having a simple structure and high maintainability.

The test was conducted by adding a bacterial solution to tap water neutralized with residual chlorine and passing the mixed test water through this primary sterilizer at a predetermined flow rate, collecting the water passing through, and measuring the number of viable bacteria. did.

The test bacteria are Escherichia coli, Staphylococcus aureus and Enterococcus. The test medium is tryptoiso broth medium (SCD medium) and standard agar medium (SA medium). The bacterial solution is inoculated with the test bacteria in an SCD medium, at 35 ° C.,
After culturing with shaking for 4 hours, the culture solution is centrifuged, the supernatant is removed, and the cells of the obtained test bacteria are suspended in sterile phosphate-buffered saline so that the number of bacteria per ml becomes about 10 ^9. Was prepared. Raw water is 10% in approximately 20 liters of tap water
It was prepared by adding 6 ml of a sodium thiosulfate solution to neutralize residual chlorine. Test water was added to 20 liters of raw water in a bacterial solution (2 ml for Escherichia coli and Staphylococcus aureus and 4 ml for enterococci).
ml) were added and mixed. In the test operation, test water is passed through the sample at the flow rates shown in Table 1, and 100 ml of the passed water is collected. The viable cell count was obtained by measuring the viable cell count of test water and passing water by a pour plate method (cultured at 35 ° C. for 2 days) using an SA medium.

[0034]

[Table 1] <1: Not detected.

As shown in Table 1, aseptic water is obtained for at least Escherichia coli, Staphylococcus aureus and Enterococcus using the primary sterilizing section of the ultraviolet sterilizing system according to one embodiment of the present invention. In addition, although O-157 is under investigation, it is considered that it becomes sterile.

The tank 21 includes a tank 22 and an inlet 23.
, An outlet 24, and an ultraviolet sterilization lamp 25.
The tank 22 stores the water purified and sterilized by the primary sterilizing section 1. The inlet 23 is disposed on the upper surface of the tank 22 and is connected to the outlet 6 of the primary sterilizing section. The outlet 24 is provided on the bottom surface of the tank, serves as an outlet for storing water, and is connected to an ice maker, a water bath, and the like. The ultraviolet sterilizing lamp 25 sterilizes water to be stored, and is disposed on the upper surface of the tank 22. In addition,

The control of turning on and off of 6 is performed by the primary sterilizing section 1 and the tank section 2.
This is performed in response to a signal from a vending machine-side control unit that controls the opening and closing of a solenoid valve 32 provided at a predetermined position of a pipe connecting 1.

[0039]

According to the present invention, since the adsorption and purification of water and the sterilization with ultraviolet rays are carried out reliably, the safety, cleanliness and hygiene of water can be ensured.

Even if the primary sterilizing section is a single container, adsorption purification and ultraviolet sterilization are surely performed, so that the apparatus can be downsized. In particular, by providing a guide tube around the ultraviolet sterilizing lamp in the primary sterilizing section, ultraviolet sterilization is performed efficiently and intensively in the tube, so that highly safe water can be supplied.

Further, by surrounding the ultraviolet sterilizing lamp in the primary sterilizing section with a guide tube, it is possible to prevent the filter from being directly irradiated with ultraviolet rays, so that deterioration (oxidation) of the filter including the adsorbent is prevented, and adsorption is prevented. The original adsorption power of the material can be exhibited. Therefore, since the purification and sterilization of water are surely performed even in one container, the size of the apparatus can be reduced, and the loss of water pressure can be suppressed.

Since the interior of the supply section is sterilized by ultraviolet rays, drinking water can be supplied cleanly and sanitarily.
