Abstract

An apparatus for collecting smoke and dust with a deodorizing function which has excellent capability for maintenance and an improved deodorizing and silencing effect, the apparatus having a housing and a bulkhead having an opening and disposed in the housing to separate a space for deodorizing and filtering exhaust gas from a space for discharging exhaust gas, a vacuuming device for vacuuming exhaust gas disposed in the space for discharging and communicating with the opening of the bulkhead, a filtering device for filtering exhaust gas disposed in the space for deodorizing and filtering and communicating with the vacuuming device through the opening of the bulkhead, and a deodorizing device for deodorizing the exhaust gas concentrically disposed at an outer side of the filtering device.

Claims

1. An apparatus for collecting smoke and dust with a deodorizing function, comprising:

a housing having a space for deodorizing and filtering exhaust gas and a space for discharging exhaust gas, which spaces are separated by a bulkhead having an opening,

a deodorizing and filtering unit located at the opening of the bulkhead in the space for deodorizing and filtering exhaust gas, wherein the deodorizing and filtering unit has a filtering means having a cylindrical shape and a deodorizing means concentrically disposed at an outer side of the filtering means, and

a vacuuming means disposed at the opening of the bulkhead for pulling exhaust gas that has passed through the deodorizing and filtering unit through the opening and into the space for discharging exhaust gas,

wherein the deodorizing and filtering unit is supported and held in the housing by a fastening member that passes through a hollow of cylindrical filtering means and two guide elements that are located in the housing along a side of the deodorizing and filtering unit.

2. The apparatus for collecting smoke and dust with a deodorizing function of claim 1, wherein there is a gap of 5-15 mm between an inside surface of the deodorizing means and an outside surface of the filtering means.

3. The apparatus for collecting smoke and dust with a deodorizing function of claim 1, wherein the vacuuming means comprises an air blower having a driving motor and further comprising a control panel having an inverter controller for controlling the driving motor of the vacuuming means.

4. The apparatus for collecting smoke and dust with a deodorizing function of claim 1, wherein the fastening member includes a stud bolt that is fixed at one end to an installation plate, which plate connects the vacuuming means to the bulkhead, and which bolt passes through the hollow of the filtering means, and a butterfly nut threaded to the other end of the stud bolt to hold the deodorizing and filtering unit in place in the housing.

5. The apparatus for collecting smoke and dust with a deodorizing function of claim 1, wherein the two guide elements are spaced with a predetermined interval between them along a side of and under the deodorizing and filtering unit and are fixed at one end to the bulkhead, and at the other end to a structure in the bottom of the space for deodorizing and filtering the exhaust gas.

6. The apparatus for collecting smoke and dust with a deodorizing function of claim 3, further comprising an acoustic absorption member disposed at an inner wall of the space for discharging exhaust gas, wherein the acoustic absorption member extends towards the driving motor of the air blower.

7. The apparatus for collecting smoke and dust with a deodorizing function of claim 6, wherein the acoustic absorption member is disposed at the inner wall of the space for discharging exhaust gas across an exhaust opening therein.

8. The apparatus for collecting smoke and dust with a deodorizing function of claim 6, wherein the acoustic absorption member has a V-shaped configuration.

9. The apparatus for collecting smoke and dust with a deodorizing function of claim 6, wherein the acoustic absorption member is covered by an acoustic insulating material.

10. The apparatus for collecting smoke and dust with a deodorizing function of claim 6,

wherein the deodorizing and filtering unit includes

the filtering means having a cylindrical shape,

the deodorizing means concentrically disposed at an outer side of the filtering means, and

cover plates disposed at both sides of the filtering means and the deodorizing means.

13. The apparatus for collecting smoke and dust with a deodorizing function of claim 1 or 11,

wherein the deodorizing means is a perforated material having an inner wall and an outer wall, and a deodorizer is located between the inner wall and the outer wall.

14. The apparatus for collecting smoke and dust with a deodorizing function of claim 13,

wherein the perforated material is a net made from a resin.

15. The apparatus for collecting smoke and dust with a deodorizing function of claim 13,

wherein the deodorizer is activated charcoal.

16. The apparatus for collecting smoke and dust with a deodorizing function of claim 15,

wherein the activated charcoal is made from palm nuts, is ground, and has an irregular form of 1-6 mm in size, and has a specific surface area of more than 1,000 m²/g.

17. The apparatus for collecting smoke and dust with a deodorizing function of claim 5,

wherein the activated charcoal is impregnated with an impregnating agent.

18. The apparatus for collecting smoke and dust with a deodorizing function of claim 17,

wherein the impregnating agent is an organic or inorganic substance that affects a specific odoriferous substance.

11. An apparatus for collecting smoke and dust with a deodorizing function, comprising:

a housing having a space for deodorizing and filtering exhaust gas and a space for discharging exhaust gas, wherein the space for deodorizing and filtering and the space for discharging are separated by a bulkhead having an opening,

a deodorizing and filtering unit provided with a filtering means having a cylindrical shape and a first deodorizing means concentrically disposed at an outer side of the filtering means, wherein the deodorizing and filtering unit is located at the opening of the bulkhead in the space for deodorizing and filtering the exhaust gas,

a vacuuming means located at the opening of the bulkhead for pulling exhaust gas that has passed through the deodorizing and filtering unit through the opening and discharging the exhaust gas through an exhaust portion thereof into the space for discharging the exhaust gas, and

a control panel for controlling the vacuuming means,

wherein the deodorizing and filtering unit is supported and held in the housing by a fastening member that passes through a hollow of the cylindrical filtering means and two guide elements that are located in the housing along a side of the deodorizing and filtering unit,

wherein the space for discharging the exhaust gas has an exhaust opening in a wall of the housing for discharging the exhaust gas to an outside of the housing,

wherein in a pathway for discharging the exhaust gas from the exhaust portion of the vacuuming means to the exhaust opening for discharging the exhaust gas, the exhaust portion is in communication with an exhaust pocket, and

wherein a second deodorizing means also having a noise absorbing function is adjacently located at a downstream side of the exhaust pocket.

12. The apparatus for collecting smoke and dust with a deodorizing function of claim 11, wherein the second deodorizing means has a two-layered structure including a deodorizing means and a filtering means.
