The dining table 10 of the embodiment of the present invention is supported by a plurality of legs 14 on the upper plate 12 as shown in FIG. 1 . The upper plate 12 has a rectangular plate shape in this embodiment. However, the upper plate 12 may have various shapes, such as a circular shape or an oval shape. Food can be placed on the top plate 12 , and components to be described below are installed. The leg 14 supports the upper plate 12 and sets the height of the upper plate 12 at the same time. The leg 14 may be at a height at which the user can use the dining table 10 while sitting on a chair, or at a height at which the user can use the dining table 10 while sitting on the floor.

The upper plate 12 has a first induction coil 16 . The first induction coil 16 is for wireless charging, and power can be supplied to the sterilization cutlery 20 to be described below by using an electromagnetic induction method or a magnetic resonance method or the like. In the present embodiment, the first induction coil 16 is formed on a portion of the left and right edges of the upper plate 12 . This is because, in general, when eating at the dining table 10 , food is placed starting from the middle of the top plate 12 , and both edges of the top plate 12 are often empty. As such, it is most efficient to form the first induction coil 16 by a predetermined width on the left or right edge of the upper plate 12 . In addition, even when the shape of the upper plate 12 is not a square, it is preferable to position the first induction coil 16 in the edge area.

In the drawings, as an example, the first induction coil 16 is shown to be formed in a circular shape, but this is an example for illustration and may be formed in an oval shape as shown in FIG. 6 . When the first induction coil 16 is formed in an elliptical shape, it may be formed to have a predetermined width along the left or right edge or edge of the upper plate 12 . In this case, when the sterilization spoon 20 is placed on the portion where the first induction coil 16 is formed, it may be placed at any position among the edges, so that the range of choices for the position where the sterilization spoon 20 is placed can be widened.

A heat source 18 may be provided at the center of the upper plate 12 . An example of the heat source 18 is an induction heater. Of course, various things may be installed as the heat source 18 . For example, a charcoal barrel may be positioned in the place of the heat source 18 , or a gas burner may be positioned to be integrated with the upper plate 12 .

The sterilization water reservoir 20 is used by being positioned on the first induction coil 16 on the upper plate 12 . The cutlery body 22 forms the outer appearance and skeleton of the sterilizing cutlery container 20 . The cutlery body 22 has an elongated hexahedral shape in this embodiment. However, the outer appearance of the cutlery body 22 may have various shapes, and the inner storage space 24 may have a shape convenient to accommodate spoons and chopsticks.

A plurality of spoons and chopsticks may be positioned in the storage space 24 . The storage space 24 is shielded from the outside by a cover 26 . The cover 26 is positioned at the entrance of the storage space 24 to shield the storage space 24 from the outside. Preferably, the cover 26 is made of a transparent or translucent material so that the inside of the storage space 24 can be seen. Of course, since UV rays for sterilization are emitted from the inside of the storage space 24, the part of the cover 26 that is located adjacent to the sterilization light 30, which will be described below, is made opaque to block UV rays from being exposed to the outside. can be

One end in the longitudinal direction of the cutlery barrel body 22 has an upper surface plate 27 . The surface of the top plate 27 is flush with the surface of the cover 26 . A substrate 28 is installed on a lower surface of the upper plate 27 , and a sterilization light 30 is provided on the substrate 28 . The sterilization light 30 provides ultraviolet rays to sterilize spoons and chopsticks.

The sterilization light 30 is installed on the lower surface of the upper plate 27 to irradiate ultraviolet rays toward the bottom of the storage space 24 , that is, a portion corresponding to the ceiling of the storage space 24 . Accordingly, the ultraviolet rays emitted from the sterilization light 30 are irradiated toward the bottom of the storage space 24 .

A wireless call bell 32 may be provided on the substrate 28 . The wireless call bell 32 is exposed through the top plate 27 . That is, the wireless call bell 32 is installed to be exposed to the upper surface of the sterilization spoon 20 so that the user can easily operate it. The wireless call bell 32 is to inform the number of the table 10 to the employee by pressing the user when calling the employee, and to provide a sound so that the employee can hear.

There is a second induction coil (34) at the bottom of the cutlery body (22). The second induction coil 34 interacts with the first induction coil 16 on the upper plate 12 of the dining table 10 to receive power. Since the second induction coil 34 is at the bottom of the cutlery body 22, when the cutlery body 22 is positioned in the area where the first induction coil 16 is formed, power is supplied to the cutlery body 22. will lose

One side of the cutlery body 22 has a battery 36 . The battery 36 serves to store power supplied by the interaction between the first induction coil 16 and the second induction coil 34 . For reference, the power charged in the battery 36 may be used to operate the sterilization light 30 or the wireless call bell 32 . Of course, the power transmitted from the second induction coil 34 may be directly used by the sterilizing light 30 or the wireless call bell 32 .

Specifically, when a current is applied to the first induction coil 16 in a state in which the first induction coil 16 and the second induction coil 34 are positioned to face each other, the first induction coil 16 and the A voltage is induced in the second induction coil 34 through electromagnetic inductive coupling between the second induction coils 34 . In this way, the battery 36 is charged by the voltage induced in the second induction coil 34 . The induced voltage is also supplied to the wireless call bell 32 and the sterilization light 30 . When the battery 36 is charged with a voltage, the voltage detection unit 38 detects the charging voltage. The charging voltage detected by the voltage detection unit 38 is transmitted to the control unit 42 .

In order to generate an induced voltage due to inductive coupling between the first and second induction coils 16 and 34, the first induction coil 16 and the second induction coil 34 are preferably positioned to face each other. Since the sterilization spoon 20 is movable, in order to induce the sterilization spoon 20 to be disposed at the position where the first induction coil 16 is formed, the first induction coil 16 is mounted on the upper plate 12. A plurality of protrusions (not shown) indicating the formed positions may be additionally formed. Preferably, four of these protrusions may be formed at positions corresponding to the size of the sterilizing spoon 20 . Accordingly, by arranging the sterilizing spoon 20 in the area made up of the four protrusions, the first induction coil 16 and the second induction coil 34 can be arranged at positions corresponding to each other. The protrusion may be used for the purpose of limiting or guiding the movement of the sterilizing spoon 20 . On the other hand, a groove or a space may be formed in the bottom of the spoon body 22 to correspond to the protrusion. The protrusion is positioned in the groove or space to prevent the cutlery body 22 from moving arbitrarily.

A switching device 40 may be installed between the battery 36 and the sterilization light 30 . Specifically, the switching device 40 is to selectively supply any one of the voltage supplied from the battery 36 and the voltage supplied from the second induction coil 34 to the sterilization light 30 . .

The switching operation of the switching element 40 is performed by the control unit 42 . In particular, the control unit 42 may control the switching device 40 using the charging voltage detected by the voltage detection unit 38 . For example, the controller 42 may control the switching device 40 so that the charging voltage of the battery 36 is supplied to the sterilizing light 30 when the charging voltage is equal to or greater than a preset reference value. Conversely, when the charging voltage is less than the reference value, the control unit 42 may control the switching device 40 so that the voltage of the second induction coil 34 is supplied to the sterilization light 30 .

In this way, the sterilization light 30 receives the voltage of the second induction coil 34 when the voltage charged in the battery 36 by the switching operation of the switching element 40 is lower than the reference value, and the When the battery 36 is sufficiently charged, the voltage of the battery 36 may be supplied. Accordingly, while the battery 36 is used, power consumption can be reduced by cutting off the power supplied to the first induction coil 16 .

The bottom of the storage space 24 of the cutlery container body 22 may have a reflective part 33 at a position facing the sterilization light 30 . The reflector 33 reflects the ultraviolet rays emitted from the sterilization light 30 and transmits them to spoons or chopsticks so that the ultraviolet rays can effectively sterilize.

Hereinafter, the use of the sterilizing spoon container according to the present invention having the configuration as described above and a dining table having the same will be described in detail.

Spoons and chopsticks are placed in the storage space 24 of the sterilization cutlery container 20 to be sterilized. To this end, the cover 26 is removed to open the storage space 24 , and spoons and chopsticks are put into the storage space 24 . At this time, the tip of the spoon and the tip of the chopsticks, that is, the portion that enters the user's mouth is positioned below the sterilizing light 30 .

When the spoon and chopsticks are placed in the storage space 24 , the cover 26 is closed so that the storage space 24 is not exposed to the outside. In this state, the sterilization light 30 may be operated. The operation of the sterilization light 30 may occur when a separate button is operated or the cover 26 is closed.

When the sterilization light 30 is operated, as shown in FIG. 5 , ultraviolet rays are mainly irradiated to the tips of spoons and chopsticks to sterilize. Some of the ultraviolet rays emitted from the sterilizing light 30 may be reflected by the reflective part 33 and transmitted to a part that is not directly touched by the sterilizing light 30 .

If the sterilization spoon 20 is positioned on the table 10 in this state, the sterilization action can occur continuously. The sterilization spoon 20 is preferably located in the area of the first induction coil 16 on the top plate 12 of the dining table 10 as shown in FIG. 1 . Of course, since the battery 36 is already charged, when the sterilization light 30 and the wireless call bell 32 are in an operable state, it does not matter if it is not in the area of the first induction coil 16 .

If the sterilization spoon 20 is in the area of the first induction coil 16, it is induced in the second induction coil 34 by inductive coupling between the first induction coil 16 and the second induction coil 34. The applied voltage is transmitted to the sterilization light 30 and the wireless call bell 32 . At this time, when the sterilization light 30 and the wireless call bell 32 are not in use, the switching device 40 is controlled by the control unit 42 so that power is supplied to the battery 36 to be charged. can

The control unit 42 controls the switching element 40 using the charging voltage detected by the voltage detection unit 38, and sets a reference value of the charging voltage in advance, and controls the switching element 40 based on this. do. The controller 42 may control the switching device 40 so that the charging voltage of the battery 36 is supplied to the sterilizing light 30 when the charging voltage is equal to or greater than a preset reference value. Conversely, when the charging voltage is less than the reference value, the control unit 42 may control the switching device 40 so that the voltage of the second induction coil 34 is supplied to the sterilization light 30 .

In this way, the sterilization light 30 receives the voltage of the second induction coil 34 when the voltage charged in the battery 36 by the switching operation of the switching element 40 is lower than the reference value, and the When the battery 36 is sufficiently charged, a voltage may be supplied from the battery 36 .

On the other hand, since the power used for the wireless call bell 32 is not very large, power is supplied through the battery 36 . However, power supply can be controlled by providing a separate switching device 40 for the wireless call bell 32 as well. The wireless call bell 32 is used by the power supplied through the battery 36, so that the user can easily call the staff.

And, as above, the spoon and chopsticks sterilized by the sterilization light 30 in the storage space 24 can be used by the user who eats at the table by opening the cover 26 .
