Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a deodorizing device used for deodorizing a room such as a hotel or an office.

[0002]

[Prior art]

 Various types of deodorizing devices are known as deodorizing devices that have been developed to deodorize indoor air. Among them, the deodorizing device that can be removed by the deodorizing filter has the structure shown in Figs. 1 and 2. There is.

That is, reference numeral 1 is a case of a deodorizing device, and an intake port 2 is formed in upper portions of both side surfaces of the case 1 and an upper surface of the case.

Below the intake port 2 inside the case 1, a guide rail 3 having an end face of a substantially U-shape is formed at symmetrical positions and extended in the front-rear direction. Thus, for example, the deodorizing filter cassette 4 filled with activated carbon is detachably accommodated and held.

[0005]

[Problems to be solved by the device]

 Thus, in the detachable structure of the cassette that allows the deodorizing filter cassette 4 to be pulled out or pushed in from the case 1 for maintenance and inspection, the peripheral frame of the deodorizing filter cassette 4 guided and held by the rails 3 is used. Since a gap is likely to be formed between the rail 5 and the rail 3, a part of the air sucked from the intake port 2 when the deodorizing device is ventilated, as shown in FIG. Since it passes through the gap between No. 3 and 3, the deodorizing efficiency is lowered.

[0006]

[Means for Solving the Problems]

 The present invention has been made in view of such a conventional defect, and provides a deodorizing device capable of enhancing the deodorizing efficiency by forming a structure in which the peripheral frame of the deodorizing filter cassette and the inner surface of the case can be hermetically joined. Especially.

Further, the present invention provides a deodorizing device capable of enhancing the workability of attaching and detaching the deodorizing filter cassette by allowing the deodorizing filter cassette to be airtightly attached to the case by one-touch operation. .

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIGS.

Reference numeral 11 denotes a case of the deodorizing device, and an intake port 12 which is the same as that of the conventional example is provided at the upper part of the case 11. Reference numeral 13 is a frame-shaped cassette receiving frame provided inside the case 11 and below the intake port 12. The upper surface of the receiving frame 13 is made of a urethane foam sheet or the like. The sealing material 14 is laid.

Further, along the left and right wall surfaces of the case 11 on the upper surface of the cassette receiving frame 13, there are provided a guide rail 15 and a guide plate 16 which are vertically spaced apart from each other. An inclined surface 17 that is inclined toward the surface of the seal material 14 is formed at the rear end portions of both guide rails 15, and the rear end portion of the guide plate 16 is formed as an inclined surface 18 that is parallel to the inclined surface 17. ing. Further, a projection-like stopper 19 is formed on the lower surface of the front end portion of the guide plate 16.

Reference numeral 20 denotes a filter cassette housed in the case 11, and the filter cassette 20 is filled with a filler such as activated carbon. Guide pins 21 guided by the guide rails 15 and stopper pins 22 engaged with the stoppers 19 are provided on both left and right wall surfaces of the filter cassette 20 so as to project therefrom.

The structure of the present embodiment is as described above. Next, the operation thereof will be described. To mount (set) the filter cassette 20 in the case 11, the filter cassette 20 is provided on both left and right wall surfaces. Slide the guide pin 21 along the guide rail 15. Immediately before the filter cassette 20 reaches the rear end of the guide rail 15, the upper edge of the filter cassette 20 is pushed down by the inclined surface 18, and at the same time, the guide pin 21 slides down on the inclined surface 17. Therefore, each edge (four-direction edge) of the lower surface of the filter cassette 20 is pressed against the surface of the seal material 14 on the cassette receiving frame 13.

When the filter cassette 20 is completely installed in the case 11, the stopper pin 22 provided on the side surface of the filter cassette 20 has passed over the ridge of the stopper 19 as shown in FIG. It is locked to the inner side surface, whereby the insertion of the filter cassette 20 into the case is completed.

As described above, in this embodiment, the filter cassette 20 is inserted into the case 11 of the deodorizing device, and at the same time, the lower peripheral edge of the filter cassette 20 is provided inside the case 11. Since the sealing material 14 is pressed against the surface of the receiving frame 13, the airtightness between the filter cassette 20 and the inside of the case 11 is enhanced, and the efficiency of cleaning air by the filter cassette is significantly improved.

Further, according to the filter cassette 20 and the case structure of the above-described embodiment, the work of inserting the filter cassette 20 into the case 11 and the work of removing the filter cassette 20 from the case 11 can be performed by one-touch operation. It has the feature that the workability of attaching and detaching the filter cassette is improved.

[0016]

[Effect of device]

 As described above, according to the present invention, in the deodorizing device having the structure in which the filter cassette 20 is detachably mounted in the case 11 of the deodorizing device, the frame-shaped receiving frame 13 having an annular shape is provided inside the case 11. An elastic sealing material 14 is formed on the upper surface of the receiving frame 13, and a guide rail 15 for slidingly guiding the filter cassette 20 is provided on a pair of edges of the receiving frame 13 and the guide rail 15. The slanted surfaces 17 and 18 for pressing the lower peripheral portion of the filter cassette 20 guided by the guide rail 15 and inserted into the case against the sealing material 14 are provided at the rear end of the Guide pins 21 guided by the guide rails 15 on the left and right side surfaces of the filter cassette 20 and when the filter cassette 20 is completely inserted into the case Since the deodorizing device is provided with the stopper pin 22 for preventing the filter cassette 20 from being detached by being locked to the case, according to this, the filter cassette 20 is inserted into the case 11 of the deodorizing device at the same time. Since the lower peripheral edge of the filter cassette 20 is pressed against the surface of the sealing material 14 on the cassette receiving frame 13 provided inside the case 11, the airtightness between the filter cassette 20 and the inside of the case 11 is maintained. As a result, the efficiency of air purification by the filter cassette is greatly improved. Further, according to this invention, the work of inserting the filter cassette 20 into the case 11 and the work of removing the filter cassette 20 from the case 11 can be performed by one-touch operation, so that the workability of attaching and detaching the filter cassette is improved. The effect is obtained.
