In the drawings, Figure 1 is an overall configuration of the deodorization deodorizing device for kitchen according to an embodiment of the present invention. 2 is an assembled view showing the filter part shown in FIG. 1, FIG. 3 is a side cross-sectional view showing the filter part shown in FIG. 1, and FIG. 4 is a planar cross-sectional view showing the filter part shown in FIG. 1. 5 is an air flow diagram of the ceramic filter illustrated in FIG. 2, and FIG. 6A is a front partial cross-sectional view illustrating the adsorption filter illustrated in FIG. 2, and FIG. 6B is a planar partial cross-sectional view illustrating the adsorption filter illustrated in FIG. 2.

As shown in FIG. 1, the deodorization apparatus 100 for a kitchen is located at an upper portion of the kitchen cooking appliance 101 and collects exhaust gas from the hood 102, and fines from the exhaust gas collected through the hood 102. Filter unit 104 to remove oil and odor, and blower 105 for exhausting the exhaust gas passing through the filter unit 104 through the flue 107.

Hereinafter will be described in detail for the deodorization deodorization device for the kitchen configured as described above.

As shown in FIG. 1, the hood 102 is positioned on the upper portion of the cooking appliance 101 to collect exhaust gas generated through cooking, and the collected exhaust gas is used to filter the grease filter 110 mounted on the hood 102. After the first pass, it flows to the filter part 104 through the exhaust pipe 103 extending to the hood 102. The grease filter 110 is a filter mentioned in Korean Utility Model Registration Application No. 2006-033008 (hereinafter referred to as 'prior art'), and the fine oil contained in the exhaust gas is dropletized to remove the fine oil from the exhaust gas. Separate. Since the grease filter 110 is described in detail in the prior art, a detailed description of the grease filter 110 will be omitted.

On the other hand, the exhaust gas passing through the grease filter 110 passes through the filter unit 104.

As shown in Figures 2 to 4, the filter portion 104 has a front portion extending in the inflow direction of the exhaust gas, the rear portion exiting the filter portion 104 has a contracted structure, the exhaust gas filter The blower 105 mounted to the rear of the unit 104 passes through the filter unit 104. Meanwhile, the upper and lower baffles 165H and 165L, the ceramic filter 120, the adsorption filter 130, the ultraviolet lamp 140, and the photocatalyst filter 150 are mounted inside the filter unit 104 in the traveling direction of the exhaust gas. . Therefore, the exhaust gas introduced into the filter unit 104 through the exhaust pipe 103 passes through the grease filter 110 between the upper and lower baffles 165H and 165L, and then passes through the ceramic filter 120 in the second place. Passing through the adsorption filter 130, and passes through the ultraviolet catalyst 140, the photocatalyst filter 150, which is the fourth filter.

The following describes the function of each filter and UV lamp before explaining the organic coupling relationship of each component.

As the exhaust gas flows into the filter unit 104, it hits the upper baffle 165H as shown in FIG. 3, flows downward, and then flows backward beyond the lower baffle 165L. At this time, while the exhaust gas hits the upper baffle 165H and the lower baffle 165L, the fine oil contained in the exhaust gas is fixed to the upper and lower baffles 165H and 165L, and dropletized and then flows down to the lower portion, through the housing 167 through the outlet port 167. 160 is discharged to the outside.

Meanwhile, the ceramic filter 120 is activated by mixing SiC (silicon carbide), Al 2 O 3, Fe 2 O 3, clay, and the like, and sintering it at about 1300 degrees to form a myriad of fine pores in the crystal. In this way, a myriad of fine pores are formed in the ceramic filter, thereby having a strong adsorption capacity. In addition, in order to maximize the adsorption capacity of the ceramic filter 120 to form a myriad of cells (cell) like a sponge. Such a cell is used to maximize the cross-sectional area of fluid contact, and forms pores of about 20 PPI (Pore Per Liner Inch).

In addition, the adsorption capacity is lost when the fine oil continues to be adsorbed to the ceramic filter 120 and saturated state, the kitchen deodorization deodorization apparatus 100 according to the present invention is the ceramic filter 120 as shown in FIG. Baffles 124 are provided at the upper and lower portions of the exhaust passage to form an exhaust passage that causes rapid air movement and vortex phenomena. The flow of the exhaust gas allows the exhaust gas to be in uniform contact with the ceramic filter 120 and at the same time serves to force the saturated oil 129 out. In addition, as the size of the baffle 124 increases, the resistance according to the air flow becomes large. At this time, as the air resistance increases, some air passes through the ceramic filter 120 having low resistance, so that the fine oil contained in the exhaust gas is the ceramic filter. Dropped to 120.

However, when the saturated oil 129 is not discharged to the ceramic filter 120, the fine oil of the exhaust gas is no longer dropleted and loses the function of the ceramic filter 120. Therefore, the ceramic filter 120 should be designed to have a self-renewal ability in which adsorption and regeneration are simultaneously performed. In the kitchen deoiling and deodorizing apparatus 100 of the present invention, as shown in FIGS. 3 and 5, by constituting a bottom for supporting the ceramic filter 120 with the perforated plate 134, the oil saturated in the ceramic filter 120 is formed. After passing through the perforated plate 134 is stored in the tank 125 is configured to be discharged. The configuration and organic coupling relationship will be described in detail later.

 On the other hand, the air passing through the ceramic filter 120 passes through the adsorption filter 130 filled with an adsorbent such as activated carbon or zeolite. An opening 136 is formed at one side of the adsorption filter 130 so as to easily fill and remove the adsorbent so that the adsorbent can be selected and filled according to the type of smell.

Such an adsorption filter 130 is arranged to be stacked in a zigzag form in order to increase the contact area with the exhaust gas in a small space, it is configured to be detachable along the guide rail 133 on the side of the filter portion (104).

The air passing through the adsorption filter 130 passes through the ultraviolet lamp 140 and finally passes through the photocatalyst filter 150. The photocatalyst filter 150 is a filter in which a photocatalyst is coated on a copper alloy material filter having a honeycomb structure, and removes the odor contained in the exhaust gas by the ultraviolet lamp 140 located in front and has a sterilization function. As another example of the photocatalyst filter 150 may be replaced by a filter coated with a photocatalyst on the activated carbon filter.

Hereinafter, the organic coupling relationship between the components of the filter unit configured as described above will be described in detail.

The filter unit 104 includes a housing 160 surrounding the ceramic filter 120, the adsorption filter 130, the ultraviolet lamp 140, and the photocatalyst filter 150.

In addition, the inside of the perforated network 134 is fixed to the nonwoven fabric 135 is fixed so that the adsorbent is not discharged through the perforated network 134.

In the rear of the adsorption filter 130 configured as described above, a plurality of ultraviolet lamps 140 are installed. The photocatalyst filter 150 is mounted at the rear of the ultraviolet lamp 140. The photocatalyst filter 150 receives the ultraviolet rays generated from the ultraviolet lamp 140 located in front, or the ultraviolet rays and the ozone, and removes the odor contained in the exhaust gas.

The exhaust gas from which the odor has been removed by passing through the photocatalyst filter 150 passes through the olfactory sensor 170 while going backward, and the olfactory sensor 170 detects the odor contained in the exhaust gas as an electrical signal. The electrical signal generated by the olfactory sensor 170 is input to the control panel 180 mounted outside the housing 160. The electrical signal input to the control panel 180 has information on the intensity of the smell so that the control panel 180 can recognize the smell contained in the exhaust gas. Therefore, when the odor is not normally included in the exhaust gas, the control panel 180 turns off the ultraviolet lamp 140, and when the odor is included in the exhaust gas, the ultraviolet light lamp (eg, by the information input from the olfactory sensor 170). 140) on. When the ultraviolet lamp 140 emits light, the photocatalyst filter 150 reacts to remove the odor contained in the exhaust gas. If it is time to replace among the filters located in front of the odor removal effect is reduced, this can be alerted through the warning lamp of the control panel 180 through the olfactory sensor 170.

Ultraviolet rays generated from such ultraviolet lamps have a sterilizing function to sterilize exhaust gases.

As described above, the exhaust gas generated in the kitchen passes through the primary grease filter 110, the secondary ceramic filter 120, the tertiary adsorption filter 130, and the quaternary photocatalyst filter 150.
