Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sterilizing device for sterilizing tableware such as glasses and teacups.

[0002]

[Prior Art]

 In accommodation facilities such as hotels and Japanese inns, every time the guest changes, the tableware such as the glass and teacups provided in each room are washed and sterilized, and a sterilized paper cover is applied as necessary, or tableware. It is housed in the case and provided to guests. Also, the provided tableware is usually placed prone to show that it is not in use.

[0003]

[Problems to be solved by the device]

 By the way, since an ultraviolet lamp is well known as a sterilizing means, if an ultraviolet lamp is provided in the tableware case, the washed tableware is housed in the tableware case and the ultraviolet lamp is turned on for a predetermined time. The desired sterilization can be carried out by itself. Further, considering that the tableware is provided in a lying state, it can be said that it is preferable to dispose the ultraviolet lamp below the base plate or the like on which the tableware is placed in terms of the sterilizing effect.

However, when the UV lamp is arranged below the tableware, when the tableware in use is stored in the tableware case again, a drop or the like flowing down from the tableware adheres to the UV lamp and stains the lamp. There is a drawback that clouding occurs, the irradiation efficiency decreases, the sterilizing power decreases, and uneven distribution occurs. Further, ultraviolet rays are blocked by the base plate or the like on which the tableware is placed, so that the tableware is likely to have a shadow, which causes a variation in sterilization, resulting in poor sterilization.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a sterilizing device for tableware, which can prevent sterilizing lamps from becoming dirty and fogging and perform sterilization accurately. is there.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, according to claim 1, at least a main body case having an opening on an upper front surface thereof, a door openably and closably provided in an opening portion of the main body case, and a space provided in the main body case. A rod-shaped support member that stands upright and supports tableware such as glasses, a sterilization lamp placed below the support member in the main body case, and an upper side of the sterilization lamp that can be opened and closed. A sterilizer for tableware is configured from the shutter.

Further, according to a second aspect of the present invention, at least a main body case having an opening on an upper front surface thereof, a door openably and closably provided in an opening portion of the main body case, and an upright standing inside the main body case with a space therebetween. A rod-shaped support member that is installed to support tableware such as glasses, a shutter that is reversibly arranged below the support member in the main case, and a germicidal lamp attached to one surface of the shutter. Therefore, it constitutes a sterilizer for tableware.

[0008]

[Action]

 In the sterilizer according to the first aspect of the present invention, the washed dishes, such as glasses and teacups, are accommodated in the main body case with the door opened, and are supported by the support member while lying down. When the shutter is manually or electrically opened to expose the sterilization lamp after the tableware is housed and the tableware is turned on, the tableware in the lying state is irradiated with the light of the sterilization lamp to sterilize the irradiated portion. Since the upper side of the germicidal lamp is covered by the shutter except when the germicidal lamp is used, even if the droplets fall from the tableware in use that is stored again in the main case, the droplets can be blocked by the shutter. .. Further, since the supporting member is composed of the rod-shaped parts, the light of the germicidal lamp is not blocked by the supporting member.

In the sterilizing apparatus according to the second aspect, when the tableware is housed and the shutter is manually or electrically reversed to turn on the sterilization lamp toward the tableware, the dishware in the prone state is irradiated with the light of the sterilization lamp. Sterilization of the irradiated portion is performed. Other functions are the same as those described in claim 1.

Sterilization can be performed in the same state, and the tableware S after sterilization can be provided to the user in a lying state. Moreover, the above-mentioned sterilization can be automatically performed by opening the shutter 6 and turning on the ultraviolet lamp 4 by a simple lever operation, so that the tableware S is frequently sterilized, such as hotels and inns. It is extremely useful for sterilization and has the advantage that sterilization can be easily performed during room service. In addition, if the operation lever 7 is placed on the bottom surface of the main body case 1 so that it cannot be seen from the external appearance so that only the person on the installation side can operate it, the mischief by the guest can be prevented. be able to.

Further, since the ultraviolet lamp 4 can be covered by the shutter 6 except during the sterilization, even if the tableware S in use is stored in the main body case 1 again, the drop that drops from the eating device is dropped. And the like can be blocked by the shutter 6, so that the ultraviolet lamp 4 can be surely prevented from being contaminated or fogged due to the adhesion of drops or the like, and the irradiation efficiency and the sterilizing power can be favorably maintained.

Further, since the supporting member 3c for supporting the tableware S is composed of the rod-shaped parts, the tableware S is not shaded when irradiated with ultraviolet rays, and the light from the ultraviolet lamp 4 is evenly distributed to the tableware S.
