Japanese Unexamined Patent Publication No. 2004-261624 (pages 4-7, FIG. 1)

  However, according to the conventional cold box, when an ion release material is used as an ion generator, the amount of ions generated decreases with time. Even when ion generation by discharge is used as the ion generator, the electrode is deteriorated by long-term driving, and the amount of generated ions is reduced. As a result, the deodorization performance of the deodorization storage is lowered, so that the ion generator needs to be replaced.

At this time, the ion generator is driven when the storage portion is higher than the first switching temperature within the temperature range, and the air flowing through the circulation duct is sterilized and deodorized by the ions generated by the ion generator. When the storage unit becomes cooler than the first switching temperature, the ion generator is stopped.

<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1: has shown the perspective view of the deodorizing storage warehouse of 1st Embodiment. The deodorization storage 1 is provided with the main-body part 2 installed in a floor surface, and the cover part 10 which covers the upper surface of the main-body part 2. As shown in FIG. The main body 2 has an outer box 3 that forms an exterior, and casters 17 and 18 (see FIG. 2) are provided on the bottom surface of the outer box 3. A handle 16 is provided on the front upper portion of the outer box 3, and the deodorization storage 1 can be moved on the floor by holding the handle 16.

  The lid 10 is pivotally supported at the rear end of the outer box 3 and opens and closes an opening 3a (see FIG. 2) on the upper surface of the outer box 3. An open button 11 that opens the lid 10 is provided at the front upper surface of the lid 10.

  FIG. 2 shows a side sectional view of the deodorization storage 1. 3 shows a perspective view of the lid 10 as viewed from below, and FIG. 4 shows a perspective view of the main body 2 as viewed from above. The outer box 3 is formed in a substantially rectangular horizontal cross section, and an opening 3a is opened on an upper surface formed of an inclined surface with the front side lowered. A machine room 5 is provided at the bottom of the outer box 3, and a storage part 4 is provided above the machine room 5 via a partition wall 9. The wall surface of the storage part 4 including the partition wall 9 is formed by filling a heat insulating material such as urethane foam.

  A lid portion 10 is pivotally supported by a hinge portion 12 at the rear end of the outer box 3. The hinge portion 12 is provided with a biasing portion 13 formed of a torsion spring that biases the lid portion 10 in the opening direction. A locking claw 31 protrudes from the lower surface of the front portion of the lid portion 10, and a hole portion 32 that engages with the locking claw 31 is provided on the front surface of the outer box 3.

  The locking claw 31 engages with the hole 32 and the lid 10 is closed. When the open button 11 is pressed, the engagement between the locking claw 31 and the hole 32 is released and the lid 10 is opened. The outer box 3 is provided with a stopper 14 that comes into contact with the lid 10 when the lid 10 is opened and restricts the rotation range. In addition, an annular packing that closes the gap between the outer box 3 and the lid 10 is provided on the periphery of the lid 10.

  The casters 17 and 18 arranged on the bottom surface of the outer box 3 are attached to the bottom plate 5 c of the machine room 5. The pair of front casters 17 have a vertical rotation axis and a horizontal rotation axis, and are mounted on the mounting surface 5a of the bottom plate 5c. The pair of rear casters 18 have a horizontal rotation shaft, and are attached to the recess 5b disposed below the attachment surface 5a.

  A compressor 7 that operates the refrigeration cycle is mounted in the recess 5b via a support plate 7a. Thereby, the compressor 11 is arrange | positioned under the accommodating part 4 which has arrange | positioned the inner case 6 mentioned later. Therefore, the installation space of the deodorizing storage 1 can be reduced, and the deodorizing storage 1 can be installed in the living room.

  Moreover, since the compressor 7 is installed in the recessed part 5b distribute | arranged below with respect to the attachment surface 5a of the caster 17, the height of the machine room 5 can be made low. Thereby, while accommodating the storage part 4 with a large internal volume, the opening part 3a of the outer case 3 can be provided in a low position.

  A cooler 8 made of a refrigerant pipe is connected to the compressor 7. The cooler 8 is arranged in the front wall and both side walls of the storage unit 4 by meandering. When the refrigeration cycle is operated by the compressor 7, the inside of the storage unit 4 is cooled by the cooler 8. That is, the compressor 7 and the cooler 8 constitute a cooling device that cools the storage unit 4. Thereby, the inside of the accommodating part 4 is maintained in the predetermined temperature range Tr (refer FIG. 9) of refrigeration temperature (0 degreeC-10 degreeC). In this embodiment, the temperature range Tr is set to 1 ° C to 5 ° C. By cooling the inside of the storage part 4 to a refrigeration temperature higher than the freezing point, it is possible to prevent the cover part 10 and the inner case 6 to be described later from sticking due to freezing of the condensed water.

  The deodorization storage 1 is provided with a normal cooling mode and a rapid cooling mode in which the cooling conditions of the storage unit 4 are different. In the normal cooling mode, the storage unit 4 is cooled by driving the compressor 7 at a predetermined number of revolutions. In the rapid cooling mode, the storage unit 4 is rapidly cooled by driving the compressor 7 at a higher number of rotations than in the normal cooling mode. . In the normal cooling mode, the compressor 7 is driven at a lower speed than in the rapid cooling mode, so that energy saving of the deodorization storage 1 can be achieved.

  A drain pipe 33 is provided in the partition wall 5 to allow the storage portion 4 to communicate with the outside of the outer box 3. Condensed water generated in the storage unit 4 due to the cooling of the storage unit 4 is drained through the drain pipe 33.

  An inner case 6 in which an upper surface is opened and waste is introduced is disposed in the storage unit 4. The inner case 6 is formed in a substantially rectangular horizontal cross section, and is taken in and out through the opening 3a. The inner case 6 is provided with a handle (not shown) that is gripped when being taken in and out. A waste bag into which waste is put may be provided in the inner case 6, and the waste bag may be taken in and out through the opening 3a.

  The storage unit 4 and the lid unit 10 are provided with a circulation duct 20 for circulating the air in the storage unit 4. The circulation duct 20 includes a lid portion duct 21 disposed on the lid portion 10 and a storage portion duct 22 disposed on the back wall of the storage portion 4.

  A temperature sensor 36 for detecting the temperature in the storage unit 4 is provided on the storage unit duct 22. Based on the detection result of the temperature sensor 36, the compressor 7 is turned on and off, and the inside of the storage part 4 is maintained in a predetermined temperature range Tr. Further, an ion generator 26 described later is turned on / off based on the detection result of the temperature sensor 36.

  5 shows a perspective view of the circulation duct 20 as viewed from above, and FIG. 6 shows a perspective view of the storage portion duct 22 as seen from the rear. The lid duct 21 of the circulation duct 20 has a suction port 21a at the front and a communication port 21b at the rear, and forms a first intake passage 21c between the suction port 21a and the communication port 21b. The communication port 21b is arranged at a position biased to the right when viewed from the front. The lower wall of the first intake passage 21c is formed in parallel to the upper surface of the lid 10 and is disposed horizontally.

  The storage part duct 22 has an air outlet 22a opened at a position biased to the left of the front surface, and a communication port 22b facing the communication port 21b opened on the upper surface. The blower outlet 22a is arranged above the upper end of the inner case 6 (see FIG. 2).

  A blower 25 composed of a centrifugal fan is disposed in the storage unit duct 22. The lower part of the storage unit duct 22 projects forward and guides the airflow to an air inlet (not shown) facing the front of the blower 25. A second intake passage 22c is formed between the communication 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 blower outlet 22a.

  On the side wall of the exhaust path 22d, an ion generator 26 that emits ions into the exhaust path 22d is disposed. The ion generator 26 has a pair of discharge electrodes (not shown), and a corona discharge is generated by applying a high voltage having an AC waveform or an impulse waveform to the discharge electrodes.

A positive voltage is applied to one of the discharge electrodes, and water molecules in the air are ionized by corona discharge to generate hydrogen ions. This hydrogen ion is clustered with water molecules in the air by solvation energy. As a result, positive ions of air ions composed of H ⁺ (H ₂ O) m (m is 0 or an arbitrary natural number) are released.

A negative voltage is applied to the other discharge electrode, and oxygen molecules or water molecules in the air are ionized by corona discharge to generate oxygen ions. This oxygen ion is clustered with water molecules in the air by solvation energy. Thereby, negative ions of air ions composed of O ₂ ⁻ (H ₂ O) n (n is an arbitrary natural number) are released.

H ⁺ (H ₂ O) m and O ₂ ⁻ (H ₂ O) n aggregate on the surface of airborne bacteria and odorous components and surround them. Then, as shown in the formulas (1) to (3), the active species [.OH] (hydroxyl radical) and H ₂ O ₂ (hydrogen peroxide) are aggregated and formed on the surface of the microorganism or the like by collision. Destroy airborne bacteria and odorous components. Here, m ′ and n ′ are arbitrary natural numbers.

  Therefore, by generating positive ions and negative ions and releasing them into the exhaust passage 22d, the airflow flowing through the exhaust passage 22d can be sterilized and deodorized. Moreover, the sterilization and deodorization in the accommodating part 4 can be performed by sending out positive ions and negative ions from the air outlet 22a.

H ⁺ (H ₂ O) m + O ₂ ⁻ (H ₂ O) n → OH + 1 / 2O ₂ + (m + n) H ₂ O (1)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ 2 OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)

  In addition, the ion generator 26 is not limited to the form which has a pair of discharge electrode, For example, a discharge electrode may be single. The ions generated by the ion generator 26 may be either positive ions or negative ions.

  A deodorizing catalyst 27 is disposed between the ion generator 26 and the outlet 22a. The deodorization catalyst 27 is formed by supporting an adsorbent such as manganese dioxide or zeolite on a honeycomb substrate, and deodorizes the air current in the duct portion 20 by chemical adsorption or physical adsorption of odor components. Thereby, the deodorizing effect in the accommodating part 4 can be improved more. Therefore, the ion generator 26 and the deodorizing catalyst 27 constitute a deodorizing device that deodorizes the inside of the storage unit 4.

  In addition, by forming the deodorization catalyst 27 in a honeycomb shape, ions generated by the ion generator 26 can pass through the deodorization catalyst 27 and suppress the disappearance of ions. The deodorizing catalyst 27 may be disposed upstream of the ion generator 26.

  Since the circulation duct 20 includes the lid part duct 21 and the storage part duct 22, and the blower 25, the ion generator 26 and the deodorization catalyst 27 are disposed in the storage part duct 22, the lid part 10 can be reduced in weight. Thereby, even if the urging | biasing force of the urging | biasing part 13 is weakened, the cover part 10 can be opened, and the burden on the user at the time of closing the cover part 10 against the urging | biasing part 13 can be eased.

  In addition, since the ion generator 26 and the blower 25 that are electrical components are not arranged on the lid 10 that is a movable part, it is not necessary to pass electrical wiring through the lid 10. In addition, the ion generator 26 and the blower 25 are not directly subjected to the impact caused by the opening and closing of the lid 10. Therefore, the reliability of the ion generator 26 and the blower 25 can be improved and the life can be extended.

  FIG. 7 shows a side cross-sectional view through the air outlet 22a at the top of the deodorization storage 1 and FIG. 8 shows a side cross-sectional view through the communication ports 21b and 22b at the top of the deodorization storage 1. By driving the blower 25 (see FIG. 6), an air flow is sent out from the rear outlet 22a into the storage portion 4 (arrow B2). The airflow sent into the storage unit 4 diffuses ions into the storage unit 4 and flows into the circulation duct 20 from the front suction port 21a through the space 34 between the lid 10 and the inner case 6. (Arrow A1).

  Thereby, an air curtain is formed in the space 34 above the inner case 6, and the outflow of odor components from the gap between the outer box 3 and the lid 10 can be further prevented. At this time, since the upper surface of the outer box 3 is formed on an inclined surface with the front side lowered, it is possible to secure a formation area of the air curtain and reduce the height of the front end of the opening 3a.

  The width × depth × height of the deodorization storage 1 is, for example, 330 mm × 440 mm × 680 mm. The width of the deodorizing storage 1 is preferably 350 mm or less. That is, the length of the care bed is about 200 mm to 220 mm, and the length of the wall surface of the living room is often about 2550 mm (1.5 tatami mats). For this reason, when the care bed is arranged along the wall surface, the deodorization storage 1 can be installed in the dead space under the care bed or overhead.

  Further, the inner case 6 has a width × depth × height of about 220 mm × about 280 mm × about 340 mm. As a result, the inner volume of the inner case 6 is about 20 L, and four daily diapers for adults used by care recipients can be accommodated for four days (weight: about 8 kg). For this reason, if the collection date of combustible waste is twice per week, the disposable diaper can be stored in the inner case 6 until the collection date.

  The width of the inner case 6 is limited by the width of the outer box 3 and the thickness of the peripheral wall of the outer box 3. If the depth of the inner case 6 is remarkably increased with respect to the lateral width, it becomes difficult to carry the inner case 6. Therefore, the depth of the inner case 6 is preferably 1.5 times or less of the lateral width. Thereby, the height of the inner case 6 is determined so as to secure a desired inner capacity (20 L in the present embodiment).

  Moreover, the height of the front end of the opening part 3a opened to the upper surface which consists of the inclined surface of the outer case 3 is formed in 500 mm-600 mm. By forming the height of the front end of the opening 3a to be 500 mm or more, the user can take out the inner case 6 or the garbage bag in the inner case 6 without bending. In addition, by setting the height of the front end of the opening 3a to 600 mm or less, it is possible to easily lift the heavy inner case 6 and the garbage bag above the opening 3a by accommodating waste. Thereby, even a woman with weak arm strength or an elderly user can easily take out the inner case 6 or the garbage bag and discard the waste.

  In the deodorization storage 1 having the above-described configuration, the lid portion 10 is opened by pressing the open button 11, waste is put into the inner case 6 or the garbage bag disposed in the inner case 6, and the lid portion 10 is closed. 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.

  Moreover, the air in the accommodating part 4 flows into the cover part duct 21 of the circulation duct 20 through the suction inlet 21a by the drive of the air blower 25 and the ion generator 26 as shown by arrow A1 (refer FIG. 8). The air that has flowed into the lid duct 21 flows through the first intake passage 21c and flows into the storage duct 22 through the communication ports 21b and 22b as shown by the arrow A2 (see FIG. 8). The air flowing into the housing duct 22 flows through the second intake passage 22c as shown by arrows A3, A4, A5 (see FIG. 6) 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. 6), and is sterilized and deodorized by the ions generated by the ion generator 26. Further, the air flowing through the exhaust passage 22d passes through the deodorization catalyst 27, and further deodorization is performed. The air that has passed through the deodorizing catalyst 27 is sent out from the outlet 22a into the storage portion 4 as shown by an arrow B2 (see FIG. 7). Ions contained in the air sent out from the air outlet 22a are diffused into the storage unit 4 and sterilization and deodorization in the storage unit 4 are performed.

  FIG. 9 is a diagram showing the relationship between the odor index and the temperature in the storage unit 4 due to the deodorization of the deodorization storage 1. The vertical axis represents the odor index, and the horizontal axis represents the temperature (unit: ° C.). In the storage unit 4, raw garbage is stored as an example of waste, and the state where the ion generator 26 is driven is indicated by a broken line Pon and the stopped state is indicated by a broken line Poff.

  The odor index is expressed by equation (1). In formula (1), N is an odor index and M is an odor concentration. The odor index N is expressed by logarithmically expressing the odor concentration M.

  N = 10 logM (1)

  Since human senses increase or decrease logarithmically, the increase or decrease in odors felt by humans can be expressed by the odor index. That is, if the change ratio of the odor concentration is the same, the change amount of the odor index is the same, and the deodorizing effect felt by a person is also the same.

  Moreover, the evaluation of the sensory test of odors by humans may be performed based on the odor intensity of 6 levels from 0 (no odor) to 5 (strong odor). When the odor intensity value changes by 1 or more, the user can feel the increase or decrease in odor. Although it differs depending on the odor component, it is known that when the odor index changes by 10 for many odor components, the odor intensity changes by 1 or more.

  According to FIG. 9, the odor index of the driving state (Pon) and the stopping state (Poff) of the ion generator 26 decreases as the temperature decreases. That is, when the storage unit 4 is at a low temperature, the evaporation of moisture containing odor components from the waste is small, and the odor concentration in the storage unit 4 is low, so the odor index is low. Further, since deodorization by ions is performed when the ion generator 26 is driven, the odor index in the driving state of the ion generator 26 is lower than the odor index in the stopped state.

  At this time, as indicated by a solid line P in the drawing, the ion generator 26 is driven between the storage portion 4 between the first switching temperature T1 and the second switching temperature T2. Further, the ion generator 26 is stopped in a period lower than the first switching temperature T1 and a period higher than the second switching temperature T2. The first switching temperature T1 is set to a temperature within a temperature range Tr in which the storage unit 4 is temperature-controlled. The second switching temperature T2 is set to a temperature higher than the temperature range Tr.

  In the figure, S1 indicates an odor index when the inside of the storage unit 4 where the ion generator 26 is stopped is at room temperature (25 ° C.), and S2 indicates an odor index that is 10 lower than the odor index S1. The odor index S1 is equivalent to the odor index in the room when waste is left in the room at room temperature.

  In the present embodiment, the temperature (4 ° C.) at which the inside of the storage unit 4 where the ion generator 26 is stopped becomes the odor index S2 is set to the first switching temperature T1. Thereby, even when the ion generator 26 is stopped during the period lower than the first switching temperature T1, the value of the odor intensity is reduced by about 1 or more as compared with the case where the waste is left in the room at room temperature. For this reason, the user can feel the deodorizing effect in a normal room at room temperature.

  In the present embodiment, the second switching temperature T2 is set to room temperature (25 ° C.). When the lid 10 is opened for a long time in summer when the living room is hot, the storage unit 4 becomes hotter than room temperature, and the odor index in the storage unit 4 is higher than the odor index S1. Similarly, when the waste is left in this room, the odor index in the room is higher than the odor index S1.

  In a period higher than normal temperature, the amount of decrease in odor index (difference between Poff and Pon) when the ion generator 26 is driven is smaller than when waste is left in the room. For this reason, even if the ion generator 26 is driven in a period higher than the second switching temperature T2 at room temperature, the user does not feel the deodorizing effect, and even if the user stops, the user does not feel the decrease in the deodorizing effect so much. .

  Therefore, if the ion generator 26 is stopped during a period lower than the first switching temperature T1 and a period higher than the second switching temperature T2, the driving time of the ion generator 26 can be reduced. Thereby, deterioration of a discharge electrode can be suppressed and the lifetime of the ion generator 26 can be extended.

  The first switching temperature T1 may be set to another temperature within the temperature range Tr. For example, the first switching temperature T1 may be set to a temperature at which the difference from the odor index S1 is an odor index greater than 10. Alternatively, the first switching temperature T1 may be set to a temperature at which the difference from the odor index S1 is an odor index smaller than 10. In this case, a deodorizing effect can be felt for some users in a room at a normal room temperature.

  Further, the second switching temperature T2 may be set to a temperature other than room temperature that is higher than the temperature range Tr. When the second switching temperature T2 is higher than room temperature, the inside of the storage unit 4 of the garbage container 1 disposed in the living room rarely reaches the second switching temperature T2. For this reason, if the 2nd switching temperature T2 is made into temperature lower than normal temperature, the drive time of the ion generator 26 can be reduced more.

  At this time, the second switching temperature T2 may be set to a temperature higher than the temperature (about 12 ° C. in FIG. 9) at which the inside of the storage unit 4 becomes the odor index S2 when the ion generator 26 is driven. Thereby, even if the ion generator 26 is driven, the ion generator 26 is stopped in a period in which the difference between the odor index in the storage unit 4 and the odor index S1 is smaller than 10. For this reason, the drive time of the ion generator 26 can be reduced, without making a user feel much the fall of a deodorizing effect.

  Alternatively, the second switching temperature T2 may be set to a temperature higher than the temperature at which the difference in odor index between when the ion generator 26 is stopped and when it is driven (about 15 ° C. in FIG. 9). As a result, the difference between the odor index when the ion generator 26 is driven and the odor index S2 becomes higher than the second switching temperature T2, and the odor index when the ion generator 26 is driven and the odor index when the ion generator 26 is stopped. The difference with is small. For this reason, even if the ion generator 26 is driven, the difference in the odor index from when the ion generator 26 is stopped is small, and the driving time of the ion generator 26 can be reduced without making the user feel more deodorizing effect.

  The first switching temperature T1 and the second switching temperature T2 can be set not only to a single value but also to a value having a width. For example, in the present embodiment, the set temperature of the first switching temperature T1 may have a range of ± 0.2 ° C. with respect to 4 ° C. Thus, the ion generator 26 is stopped when the temperature is lower than 3.8 ° C., and the ion generator 26 is driven when the temperature is higher than 4.2 ° C. Thus, by providing a range for the set temperature, it is possible to prevent the ion generator 26 from being frequently turned on and off near the set temperature.

  FIG. 10 is a flowchart showing the operation of the deodorization storage 1. When the deodorization storage 1 is turned on, it is determined in step # 11 whether or not the temperature T0 in the storage unit 4 is higher than the upper limit temperature (5 ° C.) of the temperature range Tr. If the temperature T0 is not higher than the upper limit temperature of the temperature range Tr, the process proceeds to step # 15, and if it is higher, the process proceeds to step # 12.

  In step # 12, it is determined whether or not the normal cooling mode is selected. If the rapid cooling mode is selected, the process proceeds to step # 13. In step # 13, the compressor 7 is driven at a high speed, and the process proceeds to step # 26. If the normal cooling mode is selected, the process proceeds to step # 14. In step # 14, the compressor 7 is driven at a low rotation, and the process proceeds to step # 21.

  In step # 15, it is determined whether or not the compressor 7 is driven at a high rotation speed in the rapid cooling mode. When the compressor 7 is not driven at high rotation, the process proceeds to step # 21. When the compressor 7 is driven at a high rotation, the process proceeds to step # 14, where the compressor 7 is driven at a low rotation, and the rapid cooling mode is switched to the normal cooling mode.

  In step # 21, it is determined whether or not the temperature T0 of the storage unit 4 is higher than the second switching temperature T2 (25 ° C.). If the temperature T0 is higher than the second switching temperature T2, the process proceeds to step # 26, and if not, the process proceeds to step # 22.

  In step # 22, it is determined whether or not the temperature T0 of the storage unit 4 is lower than the first switching temperature T1. If the temperature T0 is lower than the first switching temperature T1 (4 ° C.), the process proceeds to step # 26, and if not, the process proceeds to step # 23.

  In step # 23, it is determined whether or not the lid 10 is open. If the lid 10 is open, the process proceeds to step # 26, and if it is closed, the process proceeds to step # 24.

  In step # 24, the ion generator 26 is driven, and in step # 25, the blower 25 is driven, and the process proceeds to step # 31. Thereby, the deodorizing effect by ion is acquired.

  In step # 26, the ion generator 26 is stopped, and in step # 27, the blower 25 is stopped, and the process proceeds to step # 31. Thereby, in the rapid cooling mode, the ion generator 26 and the blower 25 are stopped when the temperature is lower than the first switching temperature T1, when the temperature is higher than the second switching temperature T2, and when the lid portion 10 is opened.

  When the lid 10 is opened, even if the ion generator 26 is driven, ions are released into the room and a sufficient deodorizing effect cannot be obtained. Moreover, if the cover part 10 is opened and the air blower 25 is driven, the odor component in the storage part 4 will be discharge | released indoors and will give a user discomfort. For this reason, when the cover part 10 is opened, while stopping the ion generator 26 and the air blower 25 and extending these lifetimes, discomfort can be prevented.

  In addition, since the rapid cooling mode operates according to the user's selection, there is a high possibility that the closed state of the lid 10 is maintained. For this reason, the ion generator 26 and the air blower 25 can be stopped in the rapid cooling mode to extend their life.

  In step # 31, it is determined whether or not the temperature T0 in the storage unit 4 is lower than the lower limit temperature (1 ° C.) of the temperature range Tr. If the temperature T0 is not lower than the lower limit temperature of the temperature range Tr, the process proceeds to step # 11 and steps # 11 to # 31 are repeated. When the temperature T0 is lower than the lower limit temperature of the temperature range Tr, the process proceeds to step # 32 and the compressor 7 is stopped. Then, Steps # 11 to # 32 are repeated.

  In the present embodiment, when the ion generator 26 is stopped with the lid 10 closed, the blower 25 may be driven to perform deodorization by the deodorization catalyst 27.

  According to the present embodiment, the storage unit 4 is maintained in the predetermined temperature range Tr by cooling, and the ion generator 26 is driven when the temperature is higher than the first switching temperature T1 in the temperature range Tr, and the ion generator when the temperature is low. 26 is stopped. For this reason, the ion generator 26 can be stopped when the odor concentration becomes low due to the cooling of the storage unit 4, and the life of the ion generator 26 can be extended.

  Further, when the storage unit 4 is at a temperature higher than the second switching temperature T2, which is higher than the temperature range Tr, the ion generator 26 is stopped and the compressor 7 is driven. Thereby, even if the ion generator 26 is driven, the ion generator 26 can be stopped in a high temperature period during which the user does not feel the deodorizing effect, and the life of the ion generator 26 can be further extended.

  Further, since the blower 25 is driven when the ion generator 26 is driven and the blower 25 is stopped when the ion generator 26 is stopped, the life of the blower 25 can be extended.

  In addition, when the lid 10 is opened, ions are released into the room and a sufficient deodorizing effect cannot be obtained, so that the ion generator 26 can be stopped to extend the life of the ion generator 26. At this time, by stopping the blower 25, discomfort due to the release of odorous components can be prevented.

  Further, the normal cooling mode and the rapid cooling mode are provided so as to be selectable by the user, and the ion generator 26 is stopped when the rapid cooling mode is executed. Since the rapid cooling mode is selected by the user, there is a high possibility that the closed state of the lid 10 is maintained, and the ion generator 26 can be stopped to extend the life of the ion generator 26. Further, when the rapid cooling mode is executed and the storage unit 4 is in the low temperature range Tr, the normal cooling mode is switched, so that power saving of the deodorization storage 1 can be achieved.

  Moreover, since the inside of the storage unit 4 is cooled to a refrigeration temperature higher than the freezing point (0 ° C.) by the cooler 8, it is possible to prevent the lid 10 and the inner case 6 from being fixed due to freezing of condensed water.

  Further, a suction port 21a is opened at the front portion of the lid portion duct 21 disposed on the lid portion 10, and the air outlet 22a is located above the inner case 6 of the housing portion duct 22 disposed on the back wall of the housing portion 4. Is opened, and the upper surface of the outer box 3 is formed into an inclined surface. As a result, an air curtain can be formed above the inner case 6 to prevent odor components from flowing out from the gap between the outer box 3 and the lid 10. Moreover, the height of the front end of the opening part 3a can be formed low, and the inner case 6 can be easily put in and out of the opening part 3a.

  Further, the cooler 8 is formed by a refrigerant pipe disposed on a peripheral wall (front wall, side wall) excluding the back wall of the storage unit 4. Thereby, the cooler 8 which consists of a refrigerant | coolant pipe | tube is arrange | positioned adjacent to the storage area | region of the content which has arrange | positioned the inner case 6 in the storage part 4, and a storage area | region can be cooled efficiently.

  On the upper surface of the storage unit duct 22, a communication port 22 b is opened at a position biased to the right when viewed from the front, and an air outlet 22 a is opened at a position biased to the left. A concave portion 21d that is recessed upward is provided on the lower surface of the lid duct 21 so as to face the air outlet 22a.

  FIG. 13 shows a side cross-sectional view passing through the upper outlet 22a of the deodorization storage 1. The air sent upward from the blower outlet 22a by driving the blower 25 reverses downward along the inner surface of the recess 21d as indicated by an arrow B3. A part of the air containing ions is supplied to the inside of the inner case 6 and flows into the lid duct 21 from the front suction port 21a. Thereby, while forming an air curtain in the space part 34 above the inner case 6, the inside of the inner case 6 can be sterilized and deodorized by ions. Therefore, the same effect as the first embodiment can be obtained.
