Description

  The present disclosure relates to an air conditioner.

  Conventionally, various air conditioners for adjusting air humidity, temperature, cleanliness, and the like are known. For example, Japanese Patent Application Laid-Open No. 9-225017 describes an air conditioner that removes bacteria in the air with a chemical solution. The air conditioner disclosed in Japanese Patent Laid-Open No. 9-225017 generates a flow of air by a fan, and discharges the chemical stored in the storage tank in a mist form.

  By the way, it is known that chlorine dioxide has air-conditioning effects such as removal of bacteria and viruses and deodorization. JP-A-9-225017 describes that a solution of so-called stabilized chlorine dioxide, which is a precursor of chlorine dioxide, can be used as a chemical solution. However, in the state of stabilized chlorine dioxide, an air conditioning effect equivalent to chlorine dioxide cannot be expected.

  Further, as described above, the air conditioner disclosed in Japanese Patent Laid-Open No. 9-225017 releases a mist-like chemical solution. However, it is difficult to obtain a high air conditioning effect with a mist-like chemical solution.

  An object of this indication is to provide the air conditioner which can show | play the high air conditioning effect.

  An air conditioner according to the present disclosure stores a housing having an opening, a liquid receiving portion disposed inside the housing, a chlorine dioxide aqueous solution, and dripping the chlorine dioxide aqueous solution into the liquid receiving portion. A solution tank capable of

  According to the air conditioner according to the present disclosure, a high air conditioning effect can be achieved.

FIG. 1 is a partial cross-sectional front view illustrating a schematic configuration of an air conditioner according to an embodiment. 2 is a cross-sectional view of the air conditioner shown in FIG. 1 taken along the line II-II. FIG. 3 is a longitudinal sectional view of an air conditioner according to a modification of the above embodiment. FIG. 4 is a longitudinal sectional view of an air conditioner according to another modification example of the air conditioner shown in FIG. 3. FIG. 5 is a perspective view illustrating a schematic configuration of a housing unit included in the air conditioner illustrated in FIG. 4. FIG. 6 is a plan view showing a schematic configuration of a humidifying mechanism according to a modification of the embodiment. FIG. 7 is a front view of the humidification mechanism.

  The air conditioner according to the embodiment stores a housing having an opening, a liquid receiving portion disposed inside the housing, a chlorine dioxide aqueous solution, and dripping the chlorine dioxide aqueous solution into the liquid receiving portion. A solution tank capable of

  In the air conditioner, when the chlorine dioxide aqueous solution is dropped from the solution tank to the liquid receiving part, chlorine dioxide in the dropped chlorine dioxide aqueous solution is vaporized. The vaporized chlorine dioxide (chlorine dioxide gas) is released from the opening of the housing. This chlorine dioxide gas inactivates bacteria, viruses, and the like in the room where the air conditioner is installed more reliably than the conventional air conditioner. Therefore, according to the said air conditioner, a high air harmony effect can be show | played compared with the conventional air conditioner.

  The air conditioner may further include a fan that introduces air into the housing and generates a flow of air from the liquid receiver toward the opening. According to this configuration, chlorine dioxide gas can be efficiently released from the opening of the housing.

  The air conditioner can further include a water storage tank in which water is stored. In this case, the fan may be further configured to generate an air flow that passes through the water storage tank and travels toward the opening. According to this structure, the air containing a water | moisture content can be discharge | released from the opening part of a housing | casing, and the room | chamber interior in which the air conditioner was installed can be humidified. Moreover, since bacteria, viruses, pollen, PM2.5, and the like in the room can be dropped first by the air containing moisture, the immediate effect of the air conditioning effect can be ensured. Since the fallen bacteria etc. are inactivated by the chlorine dioxide gas released from the opening of the housing, the above configuration can perform more reliable air cleaning.

  In the air conditioner, the water storage tank may be detachably attached to the housing. According to this configuration, when the air conditioner is used in a closed space where no liquid can be used, such as an aircraft or an Aegis ship, the water storage tank can be removed from the housing. Even when the water storage tank is removed from the housing, chlorine dioxide gas can be released from the opening of the housing, so that the air in the closed space can be cleaned.

  The air conditioner may further include a filter disposed in the water storage tank so that air introduced into the housing by the fan passes therethrough. According to this configuration, impurities contained in the water in the water storage tank can be removed by the filter.

  In the air conditioner, the upper end of the filter may be exposed from the water surface of the water storage tank. In this case, the liquid receiving part can be the upper end part of the filter. According to this configuration, since the chlorine dioxide aqueous solution dropped from the solution tank is difficult to mix with the water in the water storage tank, the concentration of chlorine dioxide gas released from the opening of the housing can be kept high. .

  In the above air conditioner, the liquid receiving part may be provided outside the water storage tank. According to this structure, the chlorine dioxide aqueous solution dripped from the solution tank is not mixed with the water in the water storage tank. For this reason, for example, by dropping the chlorine dioxide aqueous solution into the liquid receiving part and stopping / suppressing the generation of chlorine dioxide gas, only air containing water is substantially released from the opening of the housing. Can do. That is, the release of air containing chlorine dioxide gas and moisture can be easily controlled.

  The air conditioner may further include a water amount control unit that controls the amount of water in the water storage tank. According to this configuration, the amount of moisture in the air released from the opening of the housing by the fan can be adjusted, and as a result, the indoor humidity is adjusted.

  The air conditioner may further include vaporizing means for promoting vaporization of chlorine dioxide in the chlorine dioxide aqueous solution dropped onto the liquid receiving unit. According to this configuration, the vaporization rate of chlorine dioxide in the chlorine dioxide aqueous solution dripped from the solution tank can be increased, and the concentration of chlorine dioxide gas released from the opening of the housing can be increased.

  In the above air conditioner, the vaporizing means may include a heater for heating the chlorine dioxide aqueous solution dropped onto the liquid receiving part. Thereby, for example, even in a cold environment, chlorine dioxide in the dropped chlorine dioxide aqueous solution can be vaporized.

  In the air conditioner, the solution tank may be detachably attached to the housing. According to this configuration, when the chlorine dioxide aqueous solution in the solution tank runs out, the empty solution tank may be removed from the housing, and a new solution tank filled with the chlorine dioxide aqueous solution may be attached to the housing. The chlorine dioxide aqueous solution can be easily replenished.

  The air conditioner may further include a dropping amount control unit that controls the amount of the chlorine dioxide aqueous solution dropped from the solution tank. Thereby, the density | concentration in the air of the chlorine dioxide gas discharge | released from the opening part of a housing | casing can be adjusted.

  An air conditioner according to another embodiment includes a housing having an opening and a housing portion disposed inside the housing. The storage unit stores a solid chlorine dioxide generator that generates chlorine dioxide gas by reacting with carbon dioxide. The accommodating part is comprised so that the chlorine dioxide gas which the chlorine dioxide generator generate | occur | produced can be discharge | released.

  In the above air conditioner, chlorine dioxide gas generated by the chlorine dioxide generator is released from the housing part and further released from the opening of the housing, so that bacteria, viruses, etc. in the room where the air conditioner is installed It is more reliably deactivated compared to conventional air conditioners. Therefore, the said air conditioner also has a high air conditioning effect compared with the conventional air conditioner.

[Operation of air conditioner]
Next, operation | movement of the air conditioner 10 comprised as mentioned above is demonstrated.

  First, the user operates the operation unit 131 to start the operation of the air conditioner 10. In addition, the user performs setting operations such as indoor humidity, the amount of chlorine dioxide gas released or the concentration in the air as necessary.

  The air conditioner 10 starts control of the regulating valve 23 according to the operation start operation by the user, and drops the chlorine dioxide aqueous solution in the solution tank 2 onto the upper end portion of the filter 5 at a necessary amount and frequency. For example, the air conditioner 10 repeatedly opens and closes the regulating valve 23 at regular intervals, and supplies a chlorine dioxide aqueous solution to the upper end of the filter 5 little by little. The air conditioner 10 is configured to open and close the regulating valve 23 according to the setting of the amount of chlorine dioxide gas released by the user or the concentration in the air, the current concentration of chlorine dioxide gas in the air, and the like. Can be changed.

  The air conditioner 10 also starts controlling the adjustment valve 33 of the water tank 3. The air conditioner 10 opens and closes the regulating valve 33 in accordance with, for example, the humidity set based on the user's operation or automatically and / or the water level of the water storage tank 4, and the water in the water tank 3. Is supplied to the filter 5. As described above, the water that has passed through the filter 5 is stored in the water storage tank 4. That is, the amount of water in the water storage tank 4 is controlled by the adjustment valve 33.

  The air conditioner 10 further operates the fan 6. Air is introduced into the housing 1 by the fan 6. More specifically, the air conditioner 10 drives the motor 8 to rotate the blades 62 of the fan 6 around the rotation shaft 61. Thereby, outside air is sucked into the housing 1 through the introduction port 15.

  In FIG. 2, the flow of air generated by the fan 6 is indicated by arrows. The fan 6 generates an air flow that passes through the water storage tank 4 and the filter 5 and travels toward the opening 11.

  More specifically, the air sucked into the housing 1 from the inlet 15 first passes through the pre-filter 162 and then passes through the dust collection filter 161. The pre-filter 162 captures dust having a relatively large diameter. The dust collection filter 161 captures dust or the like that could not be captured by the pre-filter 162.

  The air that has passed through the prefilter 162 and the dust collection filter 161 flows downward along the partition wall 12 d and passes through the heater 7, the filter 5, and the water storage tank 4. Thereafter, the air passes upward between the front wall 12 a and the partition wall 12 d and is discharged from the opening 11.

  Here, when chlorine dioxide aqueous solution is dripped at the upper end part of the filter 5, the chlorine dioxide in this chlorine dioxide aqueous solution will be vaporized. The vaporized chlorine dioxide (chlorine dioxide gas) rides on the air flow generated by the fan 6 and is discharged from the opening 11. Note that the amount of chlorine dioxide gas released can be adjusted by the chlorine dioxide concentration of the chlorine dioxide aqueous solution in the solution tank 2 and the amount of chlorine dioxide aqueous solution dropped from the solution tank 2.

  When the heater 7 is ON, the air in the housing 1 can be heated by the heater 7. The heat generated by the heater 7 promotes the vaporization of chlorine dioxide in the chlorine dioxide aqueous solution dropped on the upper end of the filter 5. At the start of the operation of the air conditioner 10, it is preferable that the heater 7 is ON so that more chlorine dioxide gas can be released more quickly. However, during the operation of the air conditioner 10, the heater 7 does not always have to be ON. For example, the heater 7 may be turned on at the start of the operation of the air conditioner 10 and the heater 7 may be turned off after a predetermined time has elapsed or after the indoor chlorine dioxide concentration has exceeded a predetermined concentration.

  Moreover, when the air flow which passes the water storage tank 4 and the filter 5 is produced | generated by the fan 6, the water stored in the water storage tank 4 and the water currently hold | maintained at the filter 5 become mist shape. And discharged from the opening 11. Further, when water vapor is generated by the heat of the heater 7, the water vapor also travels on the air flow and travels toward the opening 11.

[Effect of the embodiment]
As described above, in the air conditioner 10 according to the present embodiment, when the aqueous chlorine dioxide solution is dropped from the solution tank 2 onto the upper end of the filter 5, the chlorine dioxide in the aqueous chlorine dioxide solution is vaporized and the chlorine dioxide gas. Will occur. Chlorine dioxide gas is released from the opening 11 of the housing 1. For this reason, bacteria and viruses in the room where the air conditioner 10 is installed can be reliably inactivated, and the indoor air can be effectively cleaned. Thus, if it is the said air conditioner 10, a high air conditioning effect can be show | played.

  In general, an aqueous chlorine dioxide solution is known to have a bleaching action. For this reason, in the air conditioner which discharge | releases chlorine dioxide aqueous solution in mist form, there exists a possibility of bleaching the floor surface, wall surface, etc. of the room | chamber interior in which the air conditioner is installed. On the other hand, the air conditioner 10 according to the present embodiment is configured to release chlorine dioxide gas as described above. Therefore, the air conditioner 10 can perform air cleaning without polluting the room.

  For example, when a solid chlorine dioxide agent is used as a generation source of chlorine dioxide gas, it is difficult to control the amount of chlorine dioxide gas released because the solid chlorine dioxide agent cannot be modified. However, the air conditioner 10 according to the present embodiment employs a chlorine dioxide aqueous solution as a chlorine dioxide gas generation source. For this reason, the chlorine dioxide concentration of the chlorine dioxide aqueous solution can be adjusted, and the amount of chlorine dioxide gas released can be easily controlled.

  In the air conditioner according to the present embodiment, the opening 11 is provided in the upper portion of the housing 1 in consideration that the specific gravity of chlorine dioxide gas is larger than that of air. For this reason, chlorine dioxide gas can be released from a high position, and it becomes possible to inactivate bacteria, viruses and the like floating at a high position in the room. Therefore, the air conditioning effect can be further improved.

  The air conditioner 10 according to the present embodiment includes a fan 6 that generates an air flow from the upper end of the filter 5 toward the opening 11 of the housing 1. For this reason, it is possible to efficiently release chlorine dioxide gas from the opening 11 in the air flow generated by the fan 6.

  In the air conditioner 10 according to the present embodiment, the air introduced into the housing 1 by the fan 6 also passes through the water storage tank 4. Thereby, air containing moisture can be discharged from the opening 11. Therefore, the room in which the air conditioner 10 is installed can be humidified.

  Moreover, according to the said structure, by the air containing the water | moisture content discharge | released from the opening part 11, bacteria, a virus, pollen, PM2.5, etc. which float inside can be dropped first. For this reason, the immediate effect of an air conditioning effect is securable. Note that bacteria, viruses, and the like that have fallen due to moisture-containing air are inactivated by the chlorine dioxide gas released from the opening 11, and thus are reliably removed.

  In the air conditioner 10 according to the present embodiment, the water storage tank 4 is detachably attached to the housing 1. For this reason, for example, when the air conditioner 10 is used in a closed space where liquid cannot be used, such as an aircraft or an Aegis ship, the water storage tank 4 can be removed from the housing 1. Even when the water storage tank 4 is removed from the housing 1, chlorine dioxide gas is released from the opening 11, so that the air in the closed space can be cleaned.

  In the air conditioner 10 according to the present embodiment, a filter 5 is disposed in the water storage tank 4. This filter 5 can remove impurities from the water supplied to the water storage tank 4.

  In the air conditioner 10 according to the present embodiment, the upper end portion of the filter 5 functions as a “liquid receiving portion” that receives an aqueous chlorine dioxide solution dropped from the solution tank 2. The upper end portion of the filter 5 is exposed from the water surface of the water storage tank 4. For this reason, the chlorine dioxide aqueous solution dripped from the solution tank 2 is difficult to mix with the water in the water storage tank 4, and the concentration of chlorine dioxide gas released from the opening 11 of the housing 1 can be kept high. .

  In the air conditioner 10 according to the present embodiment, the amount of water discharged from the water tank 3 is adjusted by the adjustment valve 33. That is, the amount of water in the water storage tank 4 can be controlled by the adjustment valve 33. For this reason, the moisture content in the air discharged | emitted from the opening part 11 can be adjusted, and indoor humidity can be adjusted as a result.

  The air conditioner 10 according to the present embodiment includes a heater 7. The heat generated by the heater 7 promotes vaporization of chlorine dioxide in the chlorine dioxide aqueous solution dropped on the upper end of the filter 5. Thereby, the density | concentration in the air of the chlorine dioxide gas discharge | released from the opening part 11 of the housing | casing 1 can be raised. The heater 7 can vaporize chlorine dioxide in the chlorine dioxide aqueous solution, for example, even in a cold environment.

  In the air conditioner 10 according to the present embodiment, the solution tank 2 is detachably attached to the housing 1. For this reason, when the chlorine dioxide aqueous solution in the solution tank 2 runs out, the chlorine dioxide aqueous solution can be replenished by simply replacing the solution tank 2 with a new one.

  The air conditioner 10 according to the present embodiment controls the amount of the chlorine dioxide aqueous solution dripped from the solution tank 2 by the adjustment valve 23. Thereby, the density | concentration in the air of the chlorine dioxide gas discharge | released from the opening part 11 of the housing | casing 1 can be adjusted.

[Modification]
As mentioned above, although embodiment was described, the air conditioner which concerns on this indication is not limited to the said embodiment, A various change is possible unless it deviates from the meaning.

  Although the air conditioner 10 according to the embodiment includes the water tank 3, the water storage tank 4, the filter 5, the fan 6, and the heater 7, these are not essential components. In the air conditioner 10, one or more of the water tank 3, the water storage tank 4, the filter 5, the fan 6, and the heater 7 can be omitted.

  In the above-described embodiment, the entire upper end of the housing 1 is opened, and this open portion is the opening 11, but is not particularly limited thereto. The position, number, and shape of the opening 11 in the housing 1 can be changed as appropriate.

  Although the air conditioner 10 according to the embodiment includes the heater 7 as the “vaporization unit”, the air conditioner 10 may include a “vaporization unit” other than the heater 7. For example, in the air conditioner 10, an ultraviolet irradiation device that irradiates the chlorine dioxide aqueous solution dropped from the solution tank 2 with ultraviolet rays in place of or together with the heater 7 can be provided.

  In the air conditioner 10 according to the above embodiment, the solution tank 2 is detachably attached to the housing 1, but the solution tank 2 may be configured not to be removable from the housing 1. Even if the solution tank 2 can be removed from the housing 1, the solution tank 2 does not have to be configured in a cartridge type.

  In the air conditioner 10 according to the above-described embodiment, the upper end portion of the filter 5 functions as a “liquid receiving portion”, but is not particularly limited thereto. For example, a chlorine dioxide aqueous solution may be dropped from the solution tank 2 to the water storage tank 4 so that the water storage tank 4 functions as a “liquid receiving part”, or dropped from the solution tank 2 as a “liquid receiving part”. A tray or the like for receiving a chlorine dioxide aqueous solution may be provided separately.

  For example, the air conditioner 10 </ b> A illustrated in FIG. 3 includes a solution tank 91 separately from the water storage tank 4. The solution tank 91 is disposed below the solution tank 2 in which a chlorine dioxide aqueous solution is stored.

  A filter 92 is disposed in the solution tank 91. The filter 92 is preferably wide and thin. For example, the filter 92 is disposed substantially parallel to the width direction or the depth direction of the solution tank 91. The configuration of the filter 92 is not particularly limited, but may be the same as the filter 5 in the water storage tank 4. As the filter 92 and / or the filter 5, for example, a HEPA filter or the like can be used.

  The upper end portion of the filter 92 corresponds to a “liquid receiving portion”. That is, a chlorine dioxide aqueous solution is dropped from the solution tank body 21 through the solution dropping unit 22 to the upper end of the filter 92. When the chlorine dioxide aqueous solution is dropped on the filter 92, the chlorine dioxide aqueous solution is vaporized. In the solution tank 91, the chlorine dioxide aqueous solution may be stored, but may not be stored.

  In the air conditioner 10 </ b> A, unlike the above embodiment, the carbon dioxide aqueous solution is not dropped on the filter 5 in the water storage tank 4. Therefore, only the water supplied from the water tank 3 is stored in the water storage tank 4. The water stored in the water storage tank 4 is not mixed with the chlorine dioxide aqueous solution.

  As described above, in the air conditioner 10 </ b> A, the filter 92 that is a liquid receiving portion of the chlorine dioxide aqueous solution is provided outside the water storage tank 4. For this reason, the chlorine dioxide gas and water vapor | steam discharge | released from the opening part 11 can be controlled more easily.

  For example, when it is not necessary to always spray chlorine dioxide gas, or when it is desired to reduce the amount of chlorine dioxide gas released and / or the concentration in the air, the adjustment valve 23 of the solution tank 2 is closed and the aqueous solution of dioxide is dropped onto the filter 92. Can be stopped. Thereby, generation | occurrence | production of the chlorine dioxide gas in the housing | casing 1 is stopped. As described above, since the chlorine dioxide aqueous solution is not mixed with the water in the water storage tank 4, if the generation of chlorine dioxide gas in the housing 1 is stopped, only water vapor is substantially released from the opening 11. be able to. That is, according to the air conditioner 10A, it is possible to easily perform control such as stopping or suppressing the release of chlorine dioxide gas and releasing only water vapor into the air, or releasing both chlorine dioxide gas and water vapor. it can.

  In the air conditioner 10A, the chlorine dioxide aqueous solution is dropped on the filter 92 in the solution tank 91. However, the chlorine dioxide aqueous solution may be dropped directly on the solution tank 91 without providing the filter 92 in the solution tank 91. it can. However, from the viewpoint of removing impurities, it is preferable to drop the aqueous chlorine dioxide solution on the filter 92.

  The air conditioners 10 and 10A generate chlorine dioxide gas by dropping a chlorine dioxide aqueous solution onto the liquid receiving part. However, chlorine dioxide gas can also be generated using a solid chlorine dioxide generator rather than a chlorine dioxide aqueous solution. A chlorine dioxide generator reacts with carbon dioxide in the air to generate chlorine dioxide gas. As the chlorine dioxide generator, for example, an aqueous solution containing sodium chlorite and calcined magnesium silicate impregnated with sepiolite or zeolite mineral (granular), baked and dried can be used.

  For example, like the air conditioner 10 </ b> B shown in FIG. 4, a housing portion 20 that houses a solid chlorine dioxide generator can be provided in the housing 1.

  The accommodating part 20 is comprised so that the chlorine dioxide gas which the chlorine dioxide generator generate | occur | produced can be discharge | released. For example, the storage unit 20 may include a package 201 and a case 202. The case 202 has a main body 202a and a drawer 202b.

  FIG. 5 is a perspective view showing a schematic configuration of the accommodating portion 20. The front, rear, upper, and lower shown in FIG. 5 mean front, rear, upper, and lower in a state in which the housing unit 20 is installed in the casing 1 (FIG. 4) of the air conditioner 10B.

  As shown in FIG. 5, the package 201 contains a solid chlorine dioxide generator 203. The package 201 has, for example, a rectangular parallelepiped shape or a cubic shape. However, the shape of the package 201 is not limited to this. The package 201 has air permeability in at least a part of the wall surface so that chlorine dioxide gas generated from the chlorine dioxide generator 203 can pass therethrough. For example, the front surface and the rear surface of the package 201 are formed of a breathable sheet such as a polyethylene terephthalate (PET) nonwoven fabric. The side peripheral surface of the package 201 can be made of paper, polyethylene terephthalate (PET), ABS resin, or the like.

  The package 201 before use can be stored and stored in a bag filled with an inert gas and sealed. The inert gas is a gas that does not substantially react with the chlorine dioxide generator 203. For example, nitrogen gas can be used as the inert gas. Thereby, it can suppress that the chlorine dioxide generator 203 accommodated in the package 201 deteriorates before use. The bag for storing the package 201 may be configured using a material having gas barrier properties such as aluminum. When using the package 201, the bag containing the package 201 is opened, and the package 201 is taken out of the bag and stored in the case 202.

  As described above, the case 202 includes the main body 202a and the drawer 202b that is inserted into the main body 202a. The main body 202a and the drawer 202b are formed in a bottomed box shape, for example. In the example of FIG. 5, the main body 202a has a box shape with an upper surface opened. The lead-out portion 202b has a box shape with an open front surface. The lead-out portion 202b is inserted into the main body portion 202a from the opening of the main body portion 202a. The package 201 is set in the drawer part 202b.

  The opening and closing of the case 202 is controlled by, for example, a microcomputer. That is, by the microcomputer control or the like, the drawer portion 202b is pulled out from the main body portion 202a and the case 202 is opened, or the drawer portion 202b is returned into the main body portion 202a and the case 202 is closed. Referring to FIGS. 4 and 5, when the drawing portion 202 b is drawn from the main body portion 202 a, chlorine dioxide gas generated by the chlorine dioxide generating agent 203 is released into the housing 1 and generated by the fan 6. It is discharged from the opening 11 by riding on the air flow. When the lead-out portion 202b is returned into the main body portion 202a, the release of chlorine dioxide gas from the opening portion 11 is stopped.

  The configuration of the case 202 is not limited to the above. Case 202 should just be comprised so that opening and closing is possible so that discharge of chlorine dioxide gas can be controlled. For example, the case 202 can be provided with a slide-type or door-type lid, and the lid can be opened and closed to release and stop chlorine dioxide gas.

  FIG. 4 shows a humidifying mechanism including a water tank 3, a water storage tank 4, and a filter 5 as shown in FIGS. 1 to 3, a solution tank 2, a water storage tank 4 or a solution tank 91, and a filter. A chlorine dioxide gas generation mechanism composed of 5 or 92 or the like is not shown. However, the air conditioner 10B of FIG. 4 may be configured to be attached with a humidification mechanism similar to the air conditioners 10 and 10A of FIGS. 1 to 3 and a chlorine dioxide gas generation mechanism using a chlorine dioxide aqueous solution. Good. Moreover, the air conditioner 10B may be provided with the heater 7 similarly to the air conditioners 10 and 10A.

  In the air conditioner 10B configured as described above, a chlorine dioxide gas generation mechanism (FIGS. 1 to 3) using a humidification mechanism and a chlorine dioxide aqueous solution, and chlorine dioxide gas generation using a solid chlorine dioxide generator 203 are used. A mechanism (FIGS. 4 and 5) can also be used selectively. For example, in the air conditioner 10B, normally, a humidification mechanism and a chlorine dioxide gas generation mechanism using a chlorine dioxide aqueous solution are attached, and water vapor and chlorine dioxide gas are generated by these. On the other hand, in a space where moisture is a problem, such as an aircraft, Aegis, or submarine, the humidification mechanism and the chlorine dioxide gas generation mechanism using the chlorine dioxide aqueous solution are removed from the air conditioner 10B, and the solid chlorine dioxide generator 203 is removed. The utilized chlorine dioxide gas generation mechanism can be attached to the air conditioner 10B. That is, the generation method of chlorine dioxide gas can be changed according to the environment in which the air conditioner 10B is used.

  In the above embodiment, the adjustment valves 23 and 33 that are electromagnetic valves are used to discharge water from the water tank 3 and discharge a chlorine dioxide aqueous solution from the solution tank 2. However, water and / or chlorine dioxide aqueous solution can be discharged without using a solenoid valve.

  FIG. 6 is a plan view of a water storage tank 40 having a configuration different from that of the water storage tank 4 of the above embodiment. FIG. 7 is a front view of a state in which the water tank 30 is installed in the water storage tank 40.

  As shown in FIGS. 6 and 7, the water storage tank 40 is partitioned into a first portion 402 and a second portion 403 by a partition portion 401 in which a through hole 401a is formed. The filter 5 is installed in the first portion 402. The water tank 30 is installed in the second portion 403. The second portion 403 is provided with a protruding portion 403a that protrudes upward.

  Although not shown, a water discharge port and a cap for sealing the water discharge port are provided on the lower surface of the water tank 30. The cap has a protrusion protruding downward. When the water tank 30 is installed in the second portion 403 of the water storage tank 40, the protrusion 403a of the second portion 403 pushes up the protrusion of the cap of the water tank 30, and the water in the water tank 30 is discharged. The water discharged from the water tank 30 flows not only into the second part 403 where the water tank 30 is installed, but also into the first part 402 through the through hole 401a of the partition part 401. Thereby, the water storage tank 40 is filled with water.

  Thus, according to the mechanism shown in FIGS. 6 and 7, water can be discharged from the water tank 30 and stored in the water storage tank 40 without using a solenoid valve. When water is discharged from the water tank 30 with such a mechanism, humidification ON / OFF control can be performed by the humidification sensor. The humidification sensor is also provided in the air conditioner even when water is discharged from the water tank using an electromagnetic valve.

  When a chlorine dioxide gas sensor cannot be provided in the air conditioner, it is preferable to control the amount of chlorine dioxide gas released by controlling the amount of chlorine dioxide aqueous solution dropped from the solution tank as in the above embodiment. . On the other hand, when a chlorine dioxide gas sensor can be provided in the air conditioner, the chlorine dioxide aqueous solution is discharged from the solution tank by a mechanism similar to the mechanism shown in FIGS. 6 and 7, and the amount of chlorine dioxide gas released by the chlorine dioxide gas sensor. Can be controlled.

  In short, the chlorine dioxide gas generation mechanism may be any mechanism as long as the amount of chlorine dioxide gas released can be controlled by microcomputer control or the like. Similarly, any humidifying mechanism may be used as long as humidification control is possible. That is, various mechanisms can be adopted as the mechanism for discharging water from the water tank and / or discharging the chlorine dioxide aqueous solution from the solution tank, and a mechanism using the electromagnetic valve described in the above embodiment, or The mechanism is not limited to the mechanism shown in FIGS.
