Each filter of the filter unit 20 as described above is preferably in the form of a cartridge, particularly for ease of replacement, each filter has a frame that matches the size of each compartment accommodating portion (S) of the enclosure 10 and the inlet It is preferable that the air is communicated only in the passage P connecting the outlet and there is no air inflow and outflow in the other enclosure gap.

Further, in the present invention, it is preferable that doors 13A, 13B, 13C, 13D, and 13E are provided in each compartment accommodating part S to allow the cartridge type filter to be easily entered and removed for replacement. Each door 13A is provided with an elastic hook for tightly fixing each filter 21A, 21B, 23, 25, 27 to the inside of the enclosure 10, in particular the compartment accommodating portion S, to prevent rocking. Introduced.

Looking at the elastic hook 40, first, each door engaging portion of the enclosure 10 is provided with a fixing frame 15, the fixing frame is formed with a coupling piece (15A) to increase the coupling to the enclosure Is coupled by fastening means such as bolts,

A fastening jaw 15b is formed inside the fixing frame 15, and a slot 15a is also formed.

The elastic hook 40 provided inside each of the doors 13A, 13B, 13C, 13D, and 13E is bent or integrally injection molded, as shown in FIGS. In one product,

The door joint 41, the connecting portion 43, which is connected to the joint and bent forward, the supporting portion 45 which is connected to the connecting portion and is bent toward the rear, and is connected to the supporting portion and bent toward the connecting portion. It is a form that includes the close contact fixing portion 47.

When the door is coupled to the fixing frame 15, the filter may be press-contacted by the bending peak 44 between the connecting portion 43 and the support portion 45 of the elastic hook 40,

At this time, the close fixing portion 47 is in contact with the locking step (15b) of the fixing frame (15).

The close fixing part 47 is to prevent the fluctuation of the filter as the main function, as described in detail below with respect to FIGS.

If the shape of the elastic hook is a form in which the close fixing portion 47 is omitted, if only the support portion 45 is formed, the support portion is in contact with the engaging jaw 15b.

On the other hand, when the elastic hook 40 is coupled to the fixing frame 15 fixed to the enclosure 10, the one-touch in such a way that the elastic hook 40 is caught on the locking jaw (15b) of the fixing frame (15). Type combination assembly is possible,

In addition, if the elastic hook 40 and the filter need to be separated for filter replacement and other maintenance, the one-touch type can be detached and a more perfect one-touch type detachable filter will be possible.

To this end, the fixing frame 15 is formed with a slot 15a, and when the rod or finger is inserted into the slot and the support 45 of the elastic hook is pressed, the elastic hook 40 is more easily separated from the fixing frame. can do.

Next, the process of coupling the elastic hook 40 to the fixing frame 15,

In particular, it will be described that the filter is in close contact with the compartment accommodating portion (S) in the enclosure by introducing the adhesive fixing portion 47 of the elastic hook.

That is, the elastic hook can be seen in Figures 2 and 3,

Comparing the case with and without the contact fixing portion 47 that is bent toward the connecting portion 43 at the end of the support 45, respectively,

First, in Figure 3 (A) is a case where the close fixing portion 47 is provided on the elastic hook, the straight length from the bending point 44 to the close fixing portion 47 is the support portion 45 is the connection portion 43 In the case of unfolding than the maximum compression toward), there is little change in the straight length, but more precisely, the length is longer than '1'.

When there is no close fixing part in the elastic hook as shown in (B), the straight length from the end of the supporting part P45 of the elastic hook P40 to the bending point P44 is unfolded than when the supporting part P45 is compressed to the maximum. In this case, the length is shorter by '2'.

Therefore, as shown in Figures 2 and 3, the elastic hook 40 having the close fixing portion 47 when the door is coupled to the fixing frame 15

As the locking jaw 15b of the fixing frame 15 and the elastic hook support 45 come into contact with each other, they are compressed toward the connecting portion 43.

As the support part 45 is unfolded while the end portion of the close fixing portion 47 is out of the catching jaw 15b, the close fixing portion 47 is positioned at the front of the catching jaw 15b.

At this time, since the straight length from the bending vertex 44 to the adhesion fixing part 47 becomes longer by 'l1', the filter is tightly pressed by the bending vertex.

In addition to the clearance-free coupling of such a filter is achieved due to the close fixing portion 47 of the elastic hook 40,

It may be made by a fixing protrusion 49 formed on the support portion 45 of the elastic hook 40,

That is, the relative position of the fixing protrusion 49 and the slot 15a of the fixing frame 15 is a position at which the bending peak 44 can be in close contact with the filter.

As the elastic hook 40 is coupled to the fixing frame 15, the support part 45 of the elastic hook 40 is unfolded so that the fixing protrusion 49 is fitted into the fixing frame slot 15a. The frame may be pressurized by the bending vertex.

In this case, the locking jaw 15b of the fixing frame 15 and the close fixing portion 47 of the elastic hook 40 may be omitted.

On the other hand, the fixing protrusion 49 of the elastic hook 40 is a portion that is pressed when the elastic hook 40 is separated, and the pressure of the support 45 can be made more easily due to the fixing protrusion 49. have.

Each of the fixing frame 15 is provided with a packing member (not shown) that can increase the sealing property in contact with the enclosure 10 in the engaging piece (15A), and also the packing member in each door (13a) (see Fig. 2) is provided to increase the adhesion to the fixing frame 15, the packing member 49a in contact with the fixing frame slot (15a) also in the fixing projections 49 of the elastic hook (40) (Refer FIG. 1) is provided. The packing member 49a may be omitted when a packing ring is provided around the fixing frame slot.

Next, the air filtered by the filter unit 20 passes further through the sterilization heater 50 arranged adjacent to the enclosure outlet 11B, thereby making sure that the odor causing substance is removed more.

In particular, the sterilization heater 50 is arranged to the rear of the air supply fan 30 to prevent damage to the fan by the heat, and the heater may function as an auxiliary heat source in winter.

In addition, although not shown in the enclosure 10 according to the present invention by configuring a control panel, the on-off control of the supply fan and the heater from the automatic filtering and filter replacement cycle through the more precise intake and exhaust air pollution level sensing It is possible to consider the introduction of various types of control such as to enable detection and to introduce an alarm function when the filter is replaced and an abnormal signal is detected.

As described above, the deodorizer according to the present invention comprises a filter unit including a harmful substance adsorption filter and a catalyst filter to completely remove various chemicals that are the main cause of the odor. By introducing an elastic hook into the door for each filter, the filter is housed close to the compartment containing part of the outer casing to prevent rocking, thereby facilitating maintenance, and finally eliminating chemical odor substances by oxidation and neutralization through the adsorption filter. It is possible to provide a odor removal system of one billionth (PPb) level.

In the above description, a specific type and specification of a filter related to the deodorizer and a general known technology related to a heating temperature of a heater are omitted, but those skilled in the art will naturally be able to infer and deduce it.

In addition, in the above description of the present invention with reference to the accompanying drawings, the deodorizing apparatus having a specific configuration and structure, but mainly described the present invention can be various modifications and changes by those skilled in the art, such modifications and changes are the protection of the present invention Should be interpreted as being within the scope.
