  FIG. 1 is a diagram illustrating a table mounting smoke odor eliminating apparatus according to an embodiment of the present invention. In the figure, reference numeral 10 denotes a table, and the table 10 includes a top plate 12 and legs 14. In this example, the table-mounting deodorizer / deodorizer 20 according to the present invention also constitutes a part of the legs 14 of the table 10, and the cylindrical body case 22 is fixed to the back surface of the top plate 12. 24 and the fixing bracket 26. In the main body case 22, a suction blower 27 including a fan and a motor is installed. Optionally, in the main body case 22, a heater or a cooler that warms or cools the flowing air may be installed as appropriate.

  The lower part of the main body case 22 is connected to the leg shaft 14a and serves as a discharge port 22a.

  In the upper part of the main body case 22, the suction unit 28 can slide up and down through the table 10. Therefore, the top plate 12 of the table 10 has an opening 12a having an inner diameter of about 100 mm. The opening 12a can be set by appropriately drilling the top plate 12 of an existing or new ordinary table 10. Thus, the main body case 22 and the suction unit 28 communicate with each other through the opening 12a.

  The suction unit 28 includes a cylindrical movable case 30, and a punching hole 30 a serving as a suction port is formed in an upper portion of the suction unit 28. Inside the suction unit 28, a negative ion generator 32 serving as a smoke eliminating / deodorizing unit is formed. Is installed.

  The negative ion generator 32 performs a smoke sterilization / deodorization and sterilization action. Specifically, as shown in FIG. 3, the needle electrode 34 and a cylindrical shape facing the tip of the needle electrode 34. And electrode 36. The needle electrode 34 and the cylindrical electrode 36 are disposed on the same central axis and separated by a predetermined distance. When a high voltage is applied between them, corona discharge is generated, and negative ions and ozone are generated. These negative ions adhere to and decompose the particles that make up smoke and odor, and smoke and odor are removed. Moreover, the trace amount ozone generated at the same time can deodorize the smell of tobacco.

  A plurality of negative ion generators 32 composed of the needle electrode 34 and the cylindrical electrode 36 can be provided in the cylindrical movable case 30. As an example, the negative ion generator 32 4 provided at intervals of 90 degrees on the circumference. A total of eight negative ion generators 32 can be provided in two rows.

  A high voltage generator 38 and a control device for applying to the needle electrode 34 and the cylindrical electrode 36 are fixed to the fixing plate 24 adjacent to the main body case 22 on the back side of the top plate 12 of the table 10. A cable from the high voltage generator 38 (not shown) is inserted into the main body case 22 and connected to the negative ion generator 32 in the movable case 30.

  As described above, the suction unit 28 is slidable up and down with respect to the table 10 and the main body case 22, and is the highest raised position shown in FIG. 1 and the lowest lowered position shown in FIG. 2. It is possible to move between. In order to be movable between these two positions, an operation button 42 protrudes from the side surface of the movable case 30 of the suction unit 28. The operation button 42 can be moved in and out of the movable case 30 and is always urged by the return spring 40 in a direction in which the operation button 42 projects out of the movable case 30.

  The operation of the table-mounted smoke eliminating and deodorizing apparatus 20 configured as described above will be described.

  As shown in FIG. 1, when the suction unit 28 is in the upper limit position, it is in use, and at this time, the suction blower 27 is activated, whereby the inside of the movable case 30 becomes negative pressure, and external smoke is sucked. It is sucked from the mouth 30a. When the smoke sucked into the movable case 30 reaches the negative ion generation device 32, the smoke and deodorization are instantaneously performed by the negative ions and ozone generated there. Thus, the cleaned air flow passes through the suction fan 27 and is discharged from the discharge port 22a.

  1, the upper end surface of the movable case 30 of the suction unit 28 is preferably positioned at a height of 150 to 300 mm from the top plate 12, and is seated around the table 10 at this height. Tobacco smoke from a smoker can be efficiently sucked from the suction port 30a and smoke-removed and deodorized.

  Further, when it is not necessary to use the table-installing smoke eliminating and deodorizing apparatus 20 itself, such as when the table 10 is not used, the operation button 42 is operated to lower the suction unit 28 so that the movable case 30 is moved. It can be stored in the main body case 22. Thus, it is possible to prevent the movable case 30 from interfering under the top plate 12 of the table 10 when not in use. Further, since the upper end surface of the movable case 30 of the suction unit 28 is flush with the upper surface of the top plate 12 of the table 10, the suction unit 28 does not get in the way above the top plate 12 of the table 10.

  In the illustrated embodiment, the main body case 22 of the table mounting smoke odor eliminating apparatus also serves as the legs 14 of the table 10, and is thus configured without being bulky, but is not limited thereto. Aside from the legs 14, the table 10 may be attached to the back surface of the top plate 12. Further, instead of being stored in the main body case 22, the movable case 30 can be lowered out of the main body case 22 while maintaining communication with the main body case 22.

  Further, the negative ion generator 32 is built in the suction unit 28 as a smoke eliminating / deodorizing unit. However, the present invention is not limited to this, and a filter is used together with the negative ion generator 32 or in place of the negative ion generator 32. It is also possible to provide. In addition, the smoke eliminating / deodorizing unit provided in the suction unit 28 can be removed from the top plate 12 and replaced as appropriate, and in this case, it is not necessary to remove the main body case 22, so it can be easily replaced. Work can be done.
