Description

  The present invention relates to a denture cleaner for cleaning dentures and the like at home, and more particularly to a denture cleaner with improved sterilizing effect.

  Conventionally, as a method of cleaning dentures at home, a method of cleaning and sterilizing by immersing the denture in a cleaning solution into which a drug has been added has been widely used. However, it takes a long time to decompose the soil and it is difficult to completely kill the bacteria.

  In addition, cleaning methods using dedicated denture cleaners are also used, most of which are based on ultrasonic cleaning, but cleaning with only ultrasonics has weak cleaning power, and sufficient cleaning and sterilizing effects can be expected. In addition, there is a problem that the dentures are damaged when cleaning is performed with a high energy of about 30 W in order to exert a certain level of cleaning power using only ultrasonic waves.

  Therefore, a method of cleaning by ultrasonic and low-frequency vibrations and a decomposition action using digestive enzymes (see Patent Document 1), a method of cleaning by blowing ozone into the cleaning liquid, and a cleaning device (Patent Document 2) Reference) and the like.

JP 2004-174184 A JP-A-11-244310

  However, in the cleaning method described in Patent Document 1, it is necessary to prepare a cleaning solution in which three types of digestive enzymes are dissolved each time cleaning is performed. In order to make digestive enzymes function, the temperature of the cleaning solution is changed from room temperature to body temperature. It must be kept to a certain extent and handling is complicated. Furthermore, since three types of digestive enzymes are consumed for each washing, labor and cost are required.

  On the other hand, in the cleaning method described in Patent Document 2, a cleaning device having a complicated mechanism must be used to generate ozone, and ozone gas, which is a toxic substance, is generated. There is a problem with sex.

  The present invention has been made in view of the above points, and an object thereof is to provide a denture washer having a simple structure and handling, and capable of obtaining a sufficient cleaning effect and sterilizing effect.

  In order to solve the above problems, the present invention provides the following.

  (1) A housing part in which the cleaning tank is housed, a vibrator provided below the housing part, and an ultraviolet light provided on an opening / closing lid that opens and closes the housing part above the housing part. A denture cleaning device, wherein a cleaning tank in which an antibacterial zeolite is kneaded is detachably stored in the storage unit.

  According to the present invention, the housing portion in which the cleaning tank is housed, the vibrator provided below the housing portion, and the ultraviolet light provided on the opening / closing lid that opens and closes the housing portion above the housing portion. And denaturing the dentures by irradiating ultraviolet light, so that the sterilization can be effectively performed without damaging the dentures.

  When ultraviolet light is irradiated by the ultraviolet light generating means, bacteria and viruses can be inactivated. When an appropriate amount of ultraviolet light is irradiated at an appropriate wavelength, the ultraviolet light is absorbed by DNA in the nucleus of the organism, and the absorbed ultraviolet light destroys the genetic code of bacterial and viral DNA. Bacteria and viruses cannot be propagated without the correct DNA code, and thus can be sterilized in this way. Since there is no odor or irritation caused by the drug, no drug remains, and no harmful substances are produced, it does not affect the human body and the environment, and can be used for food, drinking water, aquaculture water, and the like.

  In general, ultraviolet light exhibits a bactericidal action at a central wavelength of 100 nm to 280 nm, and particularly exhibits a bactericidal action at a wavelength near 260 nm. Here, the mercury lamp currently widely used as an ultraviolet light source can emit ultraviolet light with wavelengths of 254 nm and 185 nm, which have a particularly high bactericidal effect.

  Therefore, by irradiating the cleaning tank with ultraviolet light, bacteria and viruses attached to the dentures and the like can be inactivated and effectively sterilized without damaging the dentures and the like in the cleaning tank.

  In addition, since the denture washer is equipped with a vibrating body that applies ultrasonic vibrations or ultrasonic vibrations to the water in the cleaning tank, cleaning is performed by performing cleaning and sterilization using vibrations from the vibrating body and ultraviolet light. It is possible to perform cleaning and sterilization more effectively and safely without damaging the dentures and the like that are the object.

  That is, when ultrasonic waves are generated by the vibrating body and ultrasonic vibrations are applied to the liquid, cavitation occurs. Cavitation refers to a phenomenon in which very small bubbles are rapidly formed in a liquid or collapsed violently. The dirt is peeled off by powerful energy released when the bubbles collapse.

  Since the conventional ultrasonic cleaner is for cleaning with ultrasonic waves of a relatively low frequency of 30 KHz to 40 KHz, its cleaning ability is low, and in order to obtain a cleaning effect, it is necessary to increase the output of ultrasonic waves. . By washing with high output ultrasonic waves, teeth may be chipped or deformed during washing, and dentures may be damaged.

  In the present invention, the cleaning performance is improved by using ultrasonic waves having a relatively high frequency of 70 KHz to 100 KHz, and the cleaning effect can be obtained even if the output of the ultrasonic waves is lowered. Highly effective cleaning can be performed. Further, when a sound wave of about 130 Hz is generated by the vibrating body and the sound wave vibration is applied to the liquid, the vibration vibrates the liquid around the denture and peels off the dirt. By using low-frequency sonic vibration of about 130 Hz (8000 times / minute), cleaning can be performed without damaging the dentures during cleaning.

  Therefore, by performing cleaning and sterilization using vibration by a vibrating body and ultraviolet light, two types of cleaning and sterilization by ultrasonic vibration or sonic vibration and sterilization by ultraviolet light act, and more safely A high cleaning effect and sterilizing effect can be obtained.

  Moreover, the washing tank can obtain a higher sterilization effect by using a resin in which antibacterial zeolite is kneaded. Antibacterial zeolite is based on inorganic zeolite with a three-dimensional skeleton structure based on aluminosilicate, and metal ions in the structure are ion-exchanged with silver ions, zinc ions, copper ions, etc. having antibacterial properties. . The antibacterial zeolite used in the present invention is desirably “Zeomic” (trade name, Sinane Zeomic Co., Ltd.) in which silver ions and the like are incorporated in the structure of the zeolite. “Zeomic” can be used as a powder, and is excellent in safety, antibacterial spectrum, durability and heat resistance, and can be kneaded into a resin or the like. By using a resin in which “Zeomic” is kneaded, the antibacterial effect can be exerted against a wide range of microorganisms such as viruses, bacteria, and molds by the effect of silver ions contained in “Zeomic”.

  (2) A denture washer having a cleaning holder made of a resin kneaded with antibacterial zeolite in the cleaning tank.

  According to the present invention, a cleaning holder made of a resin in which antibacterial zeolite has been kneaded is installed in the cleaning tank. The antibacterial effect of the zeolite can be made to act more effectively at a position close to dentures and the like.

  In particular, by using a cleaning holder made of a resin in which antibacterial zeolite is kneaded and installed in a cleaning tank filled with water, the sterilizing effect and cleaning effect are enhanced in water-mediated cleaning. be able to.

  The cleaning holder according to the present invention can be used for any cleaning device that performs cleaning using water as a medium, for example, a cleaning device that performs cleaning by heating or applying an electric field. By using the cleaning holder according to the present invention, the sterilizing effect can be added or the sterilizing effect can be enhanced.

  As described above, the present invention performs cleaning and sterilization by ultraviolet light and vibration by a vibrating body, thereby safely and more effectively cleaning and sterilizing without damaging dentures or the like that are objects to be cleaned. It can be performed. Furthermore, the disinfection effect can be further enhanced by providing a cleaning tank and a cleaning holder made of a resin in which antibacterial zeolite is kneaded.

  The best mode for carrying out the present invention will be described below with reference to the drawings.
