Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

(Embodiment)
1 and 2 show a deodorizing apparatus according to an embodiment of the present invention.

As shown in the figure, the body case 1 is provided with an air inlet 2 and an air outlet 3. The main body case 1 has a honeycomb-like deodorizing element 4 that removes odors contained in the air by passing air sucked from the air inlet 2, and air is sucked from the air inlet 2 and blown out from the air outlet 3. Is provided with a blower 5 that causes the deodorizing element 4 to flow through, and a control unit 6 that controls the blower and the like.

  The deodorizing element 4 is composed of a quadrilateral honeycomb body of an adsorbing element in which the thickness in the air aeration direction for removing odor contained in the air is reduced by passing air through a large number of honeycomb-shaped cells. The deodorizing element 4 has a honeycomb cell number per inch square of 250 or less in order to reduce the pressure loss of the air passage.

  The blower 5 is constituted by a cross flow fan having a motor 7 and is provided on the upstream side of the deodorizing element 4.

The pre-filter 10 is provided at the intake port 2 to prevent clogging of dust in the deodorizing element 4, and is composed of a coarse filter 10a and a fine filter 10b, and a coarse filter on the upstream side of the intake air. 10a is provided. The storage cover 11 has a lower end claw 11a inserted into the main body case 1 as a fulcrum, and is attached to the intake port 2 so that it can be opened and closed. Moreover, the arm 11b is provided in both sides, and it is a stopper of the cover at the time of opening. Further, the arm 11 b has a fixing projection on the outside and is fixed to the main body case 1. By pushing the arm 11b inward from the left and right outer sides, the protrusion is removed, and the storage cover 2 can be easily removed. The prefilter 10 is detachably stored in the storage cover 11. Therefore, when removing the adhering dust, the storage cover 11 is opened on the front side of the main body case 1 as shown by the dotted line, the prefilter 10 is taken out, and the regenerated prefilter 10 is stored in the storage cover 11 again. Thus, the storage cover 11 is closed.

  The operation unit 13 of the deodorizing apparatus is connected to the control unit 6 and faces the front surface of the main body case 1. In addition, the arrow in a figure shows the flow of the air at the time of deodorizing.

  Next, operation | movement of the deodorizing apparatus comprised as mentioned above is demonstrated. When an operation signal is input from the operation unit 13, an operation signal is sent from the control unit 6 to the motor 7 based on a sequence set in advance according to the input.

  The blower 5 rotated by the operation of the motor 7 sucks the generated odor in the air through the pre-filter 10 from the air inlet 2 of the main body case 1.

  The inhaled odor passes through the air passage in the main body case 1 and passes through the deodorizing element 4 to be deodorized. At this time, the deodorizing element 4 is composed of a honeycomb-shaped adsorbing element and is thin in the air ventilation direction, and the number of cells per inch is 250 or less. The air blower 5 can intake a large amount of air with low noise.

  Furthermore, if dust adheres to the pre-filter 10 of the deodorizing device, the amount of blown air is reduced and the deodorizing ability is reduced. Therefore, the pre-filter 10 has a coarse filter 10a and a fine filter 10b, and dust selectively adheres to both filters according to the roughness of the dust, thereby suppressing an increase in pressure loss due to the dust. . Moreover, since the honeycomb body of the deodorizing element 4 has a cell number of 250 or less per inch, the dust that has passed through the prefilter 10 is hardly clogged in the deodorizing element 4, and the capability of the deodorizing element 4 is maintained for a long time. The deodorizing performance with a large air volume can be continued by simple cleaning of the pre-filter.

  As described above, according to the present embodiment, the following operational effects can be obtained.

That is, a body case 1 provided with an air inlet 2 and an air outlet 3 respectively, and a body case 1 provided in the body case 1 to remove odors contained in the air by passing air from the air inlet 2 To the deodorizing element 4, the blower 5 that sucks air from the air inlet 2, blows out from the outlet 3 and flows through the deodorizing element 4, the control unit 6 that controls the blower 5, and the deodorizing element 4 A pre-filter 10 that prevents clogging of dust, and a storage cover 11 that detachably stores the pre-filter 10 and that can be opened and closed on the intake port 2 side. The storage cover 11 has a claw 11a at the lower end. Can be opened and closed by being inserted into the main body case 1, and the deodorizing apparatus is configured so that the storage cover 11 can be easily attached and detached. The storage cover 11 can be made thin and compact by storing only the storage cover 11, and the claw 11 a is provided at the lower end of the storage cover 11 as a fulcrum, so that the storage cover 11 can be easily attached and detached, and the storage cover 11 is washed. It is possible to greatly improve the cleaning performance.

  The storage cover 11 is fixed to the main body case 1 by an arm 11b that determines an open position, and the arm 11b can be easily fixed. Since the storage cover 11 is fixed at a certain angle of the arm 11b, the prefilter 10 can be easily attached and detached. Moreover, it can be set as the structure which does not impair cleaning property by setting it as the structure which can be easily removed.

  Further, even when the storage cover 11 is opened to the open position, the position of the claw 11a at the lower part of the storage cover, which is a fulcrum, is set to be closer to the center of gravity so that it closes with its own weight. Thereby, the storage cover 11 is opened only when the prefilter 10 is replaced, and is closed when the support by the hand or the like is released. The storage cover 11 is not left in the opened state during replacement. Thereby, it can be set as the deodorizing apparatus of the structure which can replace | exchange the pre filter 10 safely, without touching components, such as a fan inside, easily.

  The pre-filter 10 is composed of a coarse filter 10a and a fine filter 10b, and the coarse filter 10a is provided on the air suction side. As a long-life filter with a small pressure loss, the deodorizing device can significantly improve the filter life compared to the case where finer dust is removed with the fine filter 10b and the dust is removed only with the fine filter 10b. Large air volume and long life can be achieved.

  Further, the deodorizing element 4 is a honeycomb body having a thin air ventilation direction, and the number of cells per inch square is 250 or less. By setting the size of the honeycomb body so that dust that cannot be removed by the prefilter 10 can pass through the deodorizing element 4, the deodorizing element 4 can be used for a long period of time with little pressure loss without clogging the deodorizing element 4. It becomes possible.

  The blower 5 is a deodorizing device using a cross flow fan. By using a prefilter or a deodorizing material with a small low pressure loss, and using the blower 5 as a cross flow fan, the blower 5 has a long life and is large. It can be set as a compact deodorizing apparatus with low airflow and low noise.

  As described above, in the deodorizing apparatus according to the present invention, the storage cover that stores only the prefilter can be made thin and compact. In addition, the storage cover can be easily attached and detached by simply pulling it upward with an open upper body. That is, the cleanability of the storage cover that is easily contaminated can be greatly improved. For this reason, it is useful also as a deodorizing apparatus in various apparatuses.
