FIG. 7 is a partial rear view of the circulation duct 20. In addition, the white arrow of FIGS. 4-7 shows the distribution route and distribution direction of air.

  As shown in FIGS. 3 and 4, a suction port 22 b and a blower port 22 a are opened at the upper end of the front surface of the circulation duct 20. The suction port 22b is disposed at a position biased to the right when viewed from the front, and the air outlet 22a is disposed at a position biased to the left when viewed from the front. The inlet 22b and the outlet 22a are disposed above the upper end of the inner case 6 (see FIG. 2).

  A blower 25 made of a centrifugal fan is disposed inside the circulation duct 20. The lower part of the circulation duct 20 protrudes forward and guides the airflow to the intake port facing the front of the blower 25. An intake passage 22c is formed between the suction port 22b and the intake port of the blower 25, and an exhaust passage 22d is formed between the exhaust port of the blower 25 and the outlet 22a.

  On the upper side wall 20b of the exhaust path 22d, an ion generator 26 that emits ions is disposed inside the exhaust path 22d. The ion generator 26 has a discharge electrode (not shown), and generates ions and ozone by corona discharge caused by applying a high voltage having an AC waveform or an impulse waveform to the discharge electrode. The ions generated by the ion generator 26 are preferably those having a deodorizing and sterilizing effect. For example, negative ions or a pair of positive ions and negative ions are preferable.

  A deodorizing unit 50 is detachably disposed in the exhaust path 22d between the ion generator 26 and the air outlet 22a. The deodorizing unit 50 includes a deodorizing body 51 and a housing 52.

  The deodorizing body 51 is formed by supporting a metal oxide such as manganese oxide or an adsorbent such as zeolite on a honeycomb substrate. The deodorizing body 51 deodorizes the air inside the circulation duct 20 by chemical adsorption or physical adsorption of odor components. The housing 52 is formed of a resin molded product, covers the periphery of the deodorizing body 51, and opens an air inlet 52a and an outlet 52b. The deodorizing body 51 is disposed inside the housing 52 so that the honeycomb-shaped opening face faces the inlet 52 a and the outlet 52 b of the housing 52. Thereby, the deodorizing effect inside the accommodating part 4 can be improved more.

  In the deodorization storage 1 having the above-described configuration, the lid portion 10 is opened by pressing the open button 11, and waste is introduced into the inner case 6 or the garbage bag disposed in the inner case 6 to close the lid portion 10. . The refrigeration cycle is operated by driving the compressor 7, and the inside of the storage unit 4 is cooled to the refrigeration temperature. Thereby, transpiration of moisture containing odor components from the waste is suppressed.

  Further, the air inside the storage portion 4 flows into the circulation duct 20 through the suction port 22b as shown by the arrow A1 in FIG. 4 by driving the blower 25. At this time, the ion generator 26 is driven. The air flowing into the circulation duct 20 flows through the intake passage 22c as shown by an arrow A2 (see FIG. 4) and is guided to the blower 25.

  The air exhausted from the blower 25 flows through the exhaust path 22d as shown by the arrow B1 (see FIG. 4), and is sterilized and deodorized by the ions generated by the ion generator 26. The air flowing through the exhaust path 22d flows into the housing 52 of the deodorizing unit 50 through the inflow port 52a. The air that has flowed into the housing 52 passes through the deodorizing body 51 and then flows out of the housing 52 through the outflow port 52b. Thereby, the air exhausted from the blower 25 is further deodorized.

  The air that has passed through the deodorizing body 51 and has flowed out of the outlet 52b is sent out from the outlet 22a to the inside of the storage portion 4 as shown by an arrow B2 (see FIG. 4). Ions contained in the air sent out from the air outlet 22a are diffused inside the storage unit 4, and the inside of the storage unit 4 is sterilized and deodorized.

  By disposing the ion generator 26 on the upstream side in the air flow direction of the deodorizing unit 50, the odor components adsorbed by the deodorizing body 51 are decomposed. Thereby, lifetime improvement of the deodorizing body 51 can be achieved. The deodorizing unit 50 may be arranged upstream of the ion generator 26 in the air flow direction. In this case, ions and ozone can be directly discharged from the outlet 22a to the storage unit 4.

  In addition, the housing 52 of the deodorizing unit 50 includes a lid portion 52 d disposed on the front side of the housing 52. An engaging portion 52e is provided at the center in the left-right direction of the upper end portion of the lid portion 52d. The engaging part 52e is elastically deformed when the upper end is pressed downward with fingers. Locking pieces (not shown) are provided at both ends in the left-right direction of the lower end portion of the lid portion 52d.

  On the other hand, an opening 20a is provided at a location on the front side of the deodorizing unit 50 and corresponding to the arrangement area of the deodorizing unit 50. The opening 20 a allows the deodorizing unit 50 to be attached to and detached from the outside of the circulation duct 20. Since the opening 20 a faces the inside of the storage unit 4, the deodorizing unit 50 can be attached and detached from the inside of the storage unit 4.

  After engaging the locking piece at the lower end of the lid 52d with the lower end of the opening 20a of the circulation duct 20, the deodorizing body 51 is inserted into the circulation duct 20 from the opening 20a. Then, the engaging portion 52e of the lid portion 52d is elastically deformed and engaged with the upper end of the opening 20a. Thereby, the opening 20a is closed by the lid 52d, and the deodorizing unit 50 is attached to the main body 2. At this time, as shown in FIG. 3, the lid portion 52 d is arranged facing the inside of the storage portion 4.

  Since the deodorizing performance of the deodorizing body 51 is reduced by using the deodorizing storage 1, it is necessary to replace the deodorizing body 51 after use for a predetermined period. When the deodorizing body 51 is replaced, after the lid portion 10 is opened by pressing the open button 11, the engagement portion 52e and the locking piece of the lid portion 52d of the deodorizing unit 50 are engaged with the peripheral edge of the opening portion 20a. And the deodorizing unit 50 is removed from the main body 2. Then, the replacement deodorizing unit 50 is attached to the main body 2 by engaging the engaging portion 52e and the locking piece of the replacement deodorizing unit 50 with the peripheral edge of the opening 20a.

  Here, when using the deodorization preservation | save store | warehouse | chamber 1, the deodorizing unit 50 may be removed from the main-body part 2, and the periphery of the opening part 20a may be cleaned. At this time, in order to remove liquid such as water that has entered the inside of the circulation duct 20 from the opening 20a, the circulation duct 20 includes a liquid removal unit 60 shown in FIGS.

  The liquid removing unit 60 is provided below the opening 20a inside the circulation duct 20 and on the side wall 20c below the exhaust passage 22d. The liquid removing unit 60 is provided between the opening 20a and the blower 25.
