  The air conditioner 1 connects the indoor unit 2 and the outdoor unit 6 with a connection pipe 8 to air-condition the room. In the indoor unit 2, an indoor heat exchanger 33 is placed in the center portion of the housing base 21, and a cross-flow fan type blower fan 311 having a length substantially equal to the width of the heat exchanger 33 is disposed under the heat exchanger 33.

  The electrostatic atomizer 42 includes a high voltage generator 450, an atomized particle discharge unit 430, an atomizing water generator 440, and the like.

  A high voltage of −3 kV to −6 kV generated by the high voltage generator 450 is applied to the atomization electrode 422 and the ion electrode 428, and the water supplied from the atomization water generation unit 440 is finely divided from the tip of the atomization electrode 422. And charged and released. Further, ions are released from the ion electrode 428.

  In the embodiment, an atomized particle discharge unit 430 that houses the atomizing electrode 422 and the ion electrode 428 is provided so as to protrude from the blowing air channel side wall 290 c of the indoor unit 2 to the blowing air channel 290.

  The atomizing water generating unit 440 is a method of condensing moisture from air using the Peltier effect. A cooling plate 425 serving as a heat absorption unit is attached to the low temperature part 442 of the Peltier element 441, and a heat radiation plate 338 serving as a heat radiation unit is attached to the high temperature unit 444. As shown in FIG. 7B, the cooling plate 425 is in close contact with the low temperature portion 442 of the Peltier element 441 with the electric insulating sheet 443 interposed therebetween, and cools and condenses moisture in the surrounding air.

  Below the cooling plate 425, a generated water guide 446 is provided through a space as shown in FIGS. 7A and 7B, and receives condensed water dripped and dripped on the surface of the cooling plate 425. Then, it guides to the discharge part 430 of the atomized particles. Thereby, the atomizing water condensed on the cooling plate 425 is guided by the generated water guide 446 and supplied to the atomizing electrode 422.

  The cooling surface of the cooling plate 425 faces the cooling space 425c and is provided parallel to the vertical direction. The cooling space 425c has a front opening to form a cooling space opening 425d, the front surface of which communicates with the suction air passage 270 of the heat exchanger 33, and a generated water guide 446 provided below.

  When the blower fan 311 is driven and the electrostatic atomizer 42 is operated, a negative high voltage is applied to the atomization electrode 422 and the ion electrode 428 by the high voltage generator 450.

  At this time, corona discharge occurs from the ion electrode 428 toward the surrounding air, electrons are emitted, and ions are generated. The atomized electrode 422 discharges charged fine-grained water, and the ions and charged fine-grained water are discharged to the blowout air passage 290 and are blown into the room by the blown airflow. The effect such as improving is demonstrated.

  At this time, as shown in FIG. 6, an airflow that flows from the suction port 27 to the blowout port 29 is generated by the operation of the blower fan 311, and the room air enters the suction air passage 270 of the heat exchanger 33 that communicates with the air around the Peltier element 441. Flows in. By this air flow, heat is radiated from the heat radiating plate 338 of the atomizing water generating unit 440, and moisture is supplied to the cooling plate 425, and dew condensation is generated.

  At this time, in order to improve the heat radiation from the Peltier element 441, the heat radiation fins 338a are provided on the heat radiation plate 338 attached to the high temperature portion 444. The heat dissipating fins 338a are opposed to the heat exchanger 33, and the longitudinal direction thereof is provided substantially in parallel with the vertical direction so as not to be the resistance of the suction airflow from the suction port 27 on the upper surface.

  On the other hand, through the cooling space opening 425d, the moisture in the suction air quickly moves to the cooling space 425c by the mass transfer based on the difference between the saturation absolute humidity determined by the temperature of the cooling surface and the absolute humidity determined by the temperature and humidity of the suction air. As a result, condensation occurs on the cooling surface. In this case, the cooling plate 425 is provided on the opposite side with the heat dissipation plate 338 and the Peltier element 441 interposed therebetween. Thus, the cooling plate 425 is hidden by the heat radiating plate 338 and shielded from the radiant heat from the heat exchanger 33, and the temperature of the cooling surface is not affected by the heat from the heat exchanger 33 and is stable even during heating. The water for atomization can be generated.

  By adopting such a structure, moisture in the air moves to the cooling plate 425, and condensation occurs continuously. The condensed water gradually increases, flows down the surface of the cooling plate 425 provided in parallel to the vertical direction, and drops from the lower end to the generated water guide 446 provided below. The dropped water droplets flow downward due to gravity and reach the atomizing electrode 422 of the atomized particle emitting unit 430 provided in the blowing air passage 290.

  When a high voltage is applied to the atomizing electrode 422 from the high voltage generator 450, the water of fine particles charged from the tip of the atomizing electrode 422 is atomized and blown out into the indoor space by the airflow. The atomized water of charged fine particles rides on the air current and fills the room, and as described above, exerts a deodorizing effect on the indoor air and odor components such as walls, curtains and furniture.

  In this way, the heat radiating plate 338 is sufficiently cooled by the large amount of airflow sucked into the suction air passage of the heat exchanger 33 from the suction port 27 on the upper surface of the housing by the operation of the blower fan 311, and the cooling plate 425 is reliably The dew point temperature of the air can be reduced below.

  In addition, since the cooling plate 425 is shielded from radiation from the heat exchanger 33, the temperature of the cooling surface is not affected by the heat exchanger 33, and the temperature of the room air as during heating. Even when the humidity is low, a sufficient amount of condensation can be secured.

  In general, it is known that when fine water particles are charged by electrostatic atomization and floated in a room, radicals are generated by the charges, thereby exhibiting a deodorizing action. At this time, even if the amount of water to be electrostatically atomized is very small, the number of the water becomes enormous due to nano-level fine water, and a deodorizing effect appears.

  In this way, the air-conditioning blower fan 311 is operated to flow the air around the atomizing water generating unit 440, so that a dedicated fan for the atomizing water generating unit 440 is not required, saving resources and light weight. Can be achieved. Moreover, the energy for operating the fan for exclusive use of the atomization water production | generation part 440 becomes unnecessary.

  Thus, the air conditioner of the example has an electrostatic atomizer that collects atomization water from room air, and the heat absorption part and the heat dissipation part of the electronic cooling device that collects the atomization water from the heat exchanger. It arrange | positions in an upstream suction air path, and arrange | positions the discharge | release part of the atomized particle in a blowing air path.

  Generally, the cooling amount of the low temperature part of the electronic cooling device is greatly influenced by the heat dissipation performance of the high temperature part, and if the heat dissipation of the high temperature part is not progressing smoothly, the cooling performance is improved even if the heat transfer area and heat transfer coefficient on the cooling side are increased. The improvement will be insignificant.

  In the air conditioner of an Example, the thermal radiation part of the electronic cooling apparatus which collects the water for atomization is arrange | positioned in the suction air path upstream from a heat exchanger. As a result, the heat radiating unit is placed in a large amount of airflow generated by the indoor fan that circulates the room air in order to heat and cool the room. Therefore, heat is radiated to the airflow that has almost the same temperature as the air-conditioned room. Thus, a sufficient temperature difference can be obtained and sufficient heat dissipation can be achieved.

  In addition, since the amount required to improve the quality of indoor air by electrostatic atomization is several mL / h at the most, the heat transfer area of the heat radiating part required for collecting the water for atomization necessary for this is required. Since it is known that the air volume is much smaller than the heat transfer area required for air conditioning and the required air volume, even if the heat transfer area of the heat dissipating part is slightly increased, the effect on air conditioning is negligible. Absent.

  Moreover, since the supply source of the moisture condensed in the heat absorption part is the above-described large amount of intake air having substantially the same humidity as the indoor air before being heated or cooled by the heat exchanger, the amount of moisture contained is required. A sufficient amount with respect to the amount of water for atomization and a temperature difference to the dew point is small, the dew point is reached with a small endothermic amount, and condensation can be easily performed.

  For this reason, if the amount of heat release or heat absorption is insufficient during the study process, the amount of atomization water generated can be increased by raising (lowering) the temperature on the high temperature side (low temperature side) of the electronic cooling device. Ensuring is easy. Further, by increasing the heat transfer area on the heat dissipation side and heat absorption side, it is possible to secure a heat dissipation amount and a heat absorption amount that are substantially proportional to the rate of increase in the heat transfer area, thereby reducing input to the electronic cooling device.

  Also, when the atomized particle discharge part is arranged upstream of the heat exchanger, the discharged atomized particle collides with the fin of the heat exchanger and adheres to the fin, and further, the blade of the blower or the wall of the air passage Since the remaining particles only collide with and adhere to the room, the atomized particles that reach the room are greatly reduced.

  In the present invention, since the discharge part of the atomized particles is arranged in the blowing air passage, the obstacle between the discharged atomized particles and the room is only the vertical wind direction plate, and most of the atomized particles are obstructions. It flows into the room without being disturbed and improves the air quality in the room by deodorizing. For this reason, compared with the case where a discharge part is arrange | positioned upstream of a heat exchanger, the indoor air quality is improved effectively.

  Furthermore, unlike Patent Documents 1 and 2, there is no need to provide a dedicated air blower for the electrostatic atomizer, which saves energy, space and resources, reduces the number of parts, and improves reliability.

  For this reason, the amount of atomization required indoors can be increased and the air conditioner which can reduce the input to an electronic cooling device can be provided.

  Moreover, the air conditioner of an Example arrange | positions the thermal radiation part and heat absorption part of the said electronic cooling apparatus between the side plates of the said heat exchanger.

  Thereby, since the heat absorption part and the heat radiation part are arranged by effectively utilizing the wide part from the suction port to the heat exchanger, there are few dimensional restrictions.

  In Patent Documents 1 and 2, since the electronic cooling device is arranged on the side of the heat exchanger, the width of the heat exchanger is reduced by that amount. Because the heat exchanger is wider than the same housing width, the heat transfer area of the indoor heat exchanger can be increased, and the heating and cooling performance of the air conditioner can be increased. Can be improved.

  Furthermore, by increasing the width of the heat exchanger, the suction air passage becomes wider, the wind speed of the suction airflow passing through the heat exchanger and the suction air passage is reduced, and air blowing noise and fan input are reduced. Can do.

  For this reason, the air conditioner which air-conditioning performances, such as heating and cooling capability and noise, improves can be provided.

  Moreover, the air conditioner of an Example provides the heat absorption part of the said electronic cooling device, and the discharge | release part of the said atomization particle | grains in proximity to the blowing air channel side wall of one side.

  Thereby, the flow velocity is stabilized at the side wall portion of the air passage where the air flow tends to be unstable, noise such as peeling sound is suppressed, and the audibility is improved. In addition, since the heat absorption part of the electronic cooling device and the discharge part of the atomized particles are provided close to one side of the air path, the travel distance of the generated water is short, the time required for the movement is shortened, Re-evaporation can be suppressed, and the generated atomizing water is not wasted.

  In addition, the endothermic part of the electronic cooling device and the discharge part of the atomized particles will be lined up and down, and the movement of the generated water to the discharge part of the atomized particles can be performed only by gravity. Water-retaining materials and water-absorbing materials are no longer necessary, the number of parts is reduced, and the number of assembly work steps is reduced accordingly, leading to cost reduction.

  Therefore, it is possible to provide an air conditioner in which the blowing air is stabilized and the audibility is improved, and no carrier is required for the movement of the atomizing water.

  Moreover, the air conditioner of an Example provides the said thermal radiation part facing the said heat exchanger, and provides the said heat absorption part in the position which does not oppose the said heat exchanger.

  Thereby, since a thermal radiation part is exposed to the large amount of suction | inhalation airflow which flows in into a heat exchanger, heat dissipation is performed favorably and the production | generation of the water for atomization is accelerated | stimulated. At this time, since the heat radiating part blocks the heat absorbing part and the heat exchanger and the heat absorbing part is not opposed to the heat exchanger, the influence of radiation from the heat exchanger even when the temperature of the heat exchanger is high during heating. Without generating heat, it exhibits stable endothermic performance and efficiently generates water for atomization.

  For this reason, the air conditioner which can produce | generate the water for atomization efficiently can be provided.

  In the air conditioner of the embodiment, the size of the heat radiating portion in the direction parallel to the suction surface of the heat exchanger that is orthogonal to the axis of the cross flow fan and the heat radiating portion mainly faces is the heat radiating portion in the axial direction of the cross flow fan. Longer than

  As a result, a heat radiating section is formed along the suction air flow of the heat exchanger, so that the flow of the suction air is less disturbed, and the suction air is smaller than when the dimension of the heat radiating section in the axial direction of the crossflow fan is large. The decrease in the cross-sectional area of the air flow is small, the increase in the resistance of the suction airflow can be suppressed, and the adverse effect on the refrigeration cycle can be reduced.

  For this reason, the air conditioner with a little bad influence on a refrigerating cycle when producing the water for atomization can be provided.

  Moreover, the air conditioner of an Example arrange | positions the heat absorption part and heat dissipation part of the said electronic cooling device downstream of a filter.

  Thereby, since the heat absorption part and the heat radiation part are arranged by effectively utilizing the wide part from the filter to the heat exchanger, there are few dimensional restrictions. In addition, since the dust is removed from the suction air flowing into the heat absorption part by a filter, the amount of dust contained in the condensed atomization water is small, and the transport path of the atomization water to the atomization particle generation part may be contaminated. Less.

  For this reason, the air conditioner which can always use an electrostatic atomizer in a clean state can be provided.

  Next, processing when the generation of atomizing water becomes excessive will be described with reference to FIGS. FIG. 9 is a front view of the excess water treatment unit.

  A generated water guide 446 is disposed below the cooling plate 425 of the atomizing water generating unit 440 and receives dripping water from the cooling plate 425. The generated water guide 446 is provided with a trough 446a serving as an excessive dew condensation water treatment channel. When the generated water is accumulated at the bottom of the generated water guide 446 when the generation of the atomizing water is excessive, it passes along the trough 446a and the excessive dew condensation water is generated. It falls to the lower excess water receiving member 447 serving as a processing means.

  The excess water receiving member 447 is a water-absorbing sheet-like member attached to the bottom inner surface of the decorative frame 23. Excess water generated from the ridge 446a spreads rapidly on the member and spreads on the sheet, and is exposed to room air. In response to the heat from the bottom of the decorative frame 23, it quickly evaporates from the diffused wide surface. By configuring in this way, even when condensation exceeding the amount consumed by atomization occurs when the humidity of indoor air is high, excess condensed water evaporates indoors on the excess water receiving member 447, Even when the indoor humidity is high, the interior and surroundings of the indoor unit 2 are not wetted with excessive dew condensation water.

  As described above, the air conditioner of the embodiment includes the excessive dew condensation water treatment water channel that branches from the middle of the conveyance path that conveys the dew condensation water from the atomization water generation unit to the discharge unit, and the excessive dew condensation provided at the end thereof. Has water treatment means.

  As a result, even if the amount of atomized particles released is less than the generation of atomization water, the excess atomization water flows into the excess dew condensation water treatment channel, and is treated by the excess dew condensation water treatment means at the end. It does not drop or blow out with water droplets from the outlet.

  For this reason, the air conditioner which does not have a possibility that the atomization water which became excess indoors dripped or blows out can be provided.

  In the air conditioner of the embodiment, the excess water treatment means is a water retaining material disposed on the inner surface of the outer casing.

  As a result, the excessive dew condensation water is absorbed by the water retention material, spontaneously evaporates from the surface, and does not drop out of the casing.

  For this reason, it is possible to provide an air conditioner that has a simple configuration and does not allow excessive dew condensation water to spontaneously evaporate and drop out of the casing.

  As described above, according to the air conditioner of claim 1, the heat absorption part and the heat dissipation of the electronic cooling device that has the electrostatic atomizer that collects the atomizing water from the indoor air and collects the atomizing water. A part is arrange | positioned in the suction air path upstream from a heat exchanger, and the discharge | release part of the atomization particle | grain is arrange | positioned in a blowing air path.

  Thereby, the thermal radiation part of the electronic cooling device which collects the water for atomization is arrange | positioned in the suction air path upstream from a heat exchanger. As a result, the heat radiating unit is placed in a large amount of airflow generated by the indoor fan that circulates the room air in order to heat and cool the room. Therefore, heat is radiated to the airflow that has almost the same temperature as the air-conditioned room. Thus, a sufficient temperature difference can be obtained and sufficient heat dissipation can be achieved.

  In addition, since the amount required to improve the quality of indoor air by electrostatic atomization is several mL / h at the most, the heat transfer area of the heat radiating part required for collecting the water for atomization necessary for this is required. Since it is known that the air volume is much smaller than the heat transfer area required for air conditioning and the required air volume, even if the heat transfer area of the heat dissipating part is slightly increased, the effect on air conditioning is negligible. Absent.

  Moreover, since the supply source of the moisture condensed in the heat absorption part is the above-described large amount of intake air having substantially the same humidity as the indoor air before being heated or cooled by the heat exchanger, the amount of moisture contained is required. A sufficient amount with respect to the amount of water for atomization and a temperature difference to the dew point is small, the dew point is reached with a small endothermic amount, and condensation can be easily performed.

  For this reason, if the amount of heat release or heat absorption is insufficient during the study process, the amount of atomization water generated can be increased by raising (lowering) the temperature on the high temperature side (low temperature side) of the electronic cooling device. Ensuring is easy. Further, by increasing the heat transfer area on the heat dissipation side and heat absorption side, it is possible to secure a heat dissipation amount and a heat absorption amount that are substantially proportional to the rate of increase in the heat transfer area, thereby reducing input to the electronic cooling device.

  Also, when the atomized particle discharge part is arranged upstream of the heat exchanger, the discharged atomized particle collides with the fin of the heat exchanger and adheres to the fin, and further, the blade of the blower or the wall of the air passage Since the remaining particles only collide with and adhere to the room, the atomized particles that reach the room are greatly reduced.

  In the present invention, since the discharge part of the atomized particles is arranged in the blowing air passage, the obstacle between the discharged atomized particles and the room is only the vertical wind direction plate, and most of the atomized particles are obstructions. It flows into the room without being disturbed and improves the air quality in the room by deodorizing. For this reason, compared with the case where a discharge part is arrange | positioned upstream of a heat exchanger, the indoor air quality is improved effectively.

  Furthermore, unlike Patent Documents 1 and 2, there is no need to provide a dedicated air blower for the electrostatic atomizer, which saves energy, space and resources, reduces the number of parts, and improves reliability.

  For this reason, the amount of atomization required indoors can be increased and the air conditioner which can reduce the input to an electronic cooling device can be obtained.

  Moreover, according to the air conditioner of Claim 2, the thermal radiation part and heat absorption part of the said electronic cooling device are arrange | positioned between the side plates of the said heat exchanger.

  Thereby, since the heat absorption part and the heat radiation part are arranged by effectively utilizing the wide part from the suction port to the heat exchanger, there are few dimensional restrictions.

  In Patent Documents 1 and 2, since the electronic cooling device is arranged on the side of the heat exchanger, the width of the heat exchanger is reduced by that amount. Because the heat exchanger is wider than the same housing width, the heat transfer area of the indoor heat exchanger can be increased, and the heating and cooling performance of the air conditioner can be increased. Can be improved.

  Furthermore, by increasing the width of the heat exchanger, the suction air passage becomes wider, the wind speed of the suction airflow passing through the heat exchanger and the suction air passage is reduced, and blowing noise and fan input are reduced. Can do.

  For this reason, the air conditioner which air-conditioning performances, such as heating and cooling capability and noise, improves can be obtained.

  According to the air conditioner of the third aspect, the heat absorption part of the electronic cooling device and the discharge part of the atomized particles are provided close to the blowout air channel side wall on one side.

  Thereby, the flow velocity is stabilized at the side wall portion of the air passage where the air flow tends to be unstable, noise such as peeling sound is suppressed, and the audibility is improved. In addition, since the heat absorption part of the electronic cooling device and the discharge part of the atomized particles are provided close to one side of the air path, the travel distance of the generated water is short, the time required for the movement is shortened, Re-evaporation can be suppressed, and the generated atomizing water is not wasted.

  In addition, the endothermic part of the electronic cooling device and the discharge part of the atomized particles will be lined up and down, and the movement of the generated water to the discharge part of the atomized particles can be performed only by gravity. Water-retaining materials and water-absorbing materials are no longer necessary, the number of parts is reduced, and the number of assembly work steps is reduced accordingly, leading to cost reduction.

  Therefore, it is possible to obtain an air conditioner in which the blowing air is stabilized and the audibility is improved, and no carrier is required for the movement of the atomizing water.

  Moreover, according to the air conditioner of Claim 4, the said heat radiating part is provided facing the said heat exchanger, and the said heat absorption part is provided in the position which does not face the said heat exchanger.

  Thereby, since a thermal radiation part is exposed to the large amount of suction | inhalation airflow which flows in into a heat exchanger, heat dissipation is performed favorably and the production | generation of the water for atomization is accelerated | stimulated. At this time, since the heat radiating part blocks the heat absorbing part and the heat exchanger and the heat absorbing part is not opposed to the heat exchanger, the influence of radiation from the heat exchanger even when the temperature of the heat exchanger is high during heating. Without generating heat, it exhibits stable endothermic performance and efficiently generates water for atomization.

  For this reason, the air conditioner which can produce | generate the water for atomization efficiently can be obtained.

  According to the air conditioner of claim 5, the dimension of the heat radiating portion in a direction perpendicular to the axis of the cross flow fan and parallel to the suction surface of the heat exchanger facing the heat radiating portion mainly is the axial direction of the cross flow fan. It is longer than the dimension of the heat radiation part.

  As a result, a heat radiating section is formed along the suction air flow of the heat exchanger, so that the flow of the suction air is less disturbed, and the suction air is smaller than when the dimension of the heat radiating section in the axial direction of the crossflow fan is large. The decrease in the cross-sectional area of the air flow is small, the increase in the resistance of the suction airflow can be suppressed, and the adverse effect on the refrigeration cycle can be reduced.

  For this reason, an air conditioner having a small adverse effect on the refrigeration cycle when generating the atomizing water can be obtained.

  According to the air conditioner of the sixth aspect, the heat absorption part and the heat radiation part of the electronic cooling device are arranged downstream of the filter.

  Thereby, since the heat absorption part and the heat radiation part are arranged by effectively utilizing the wide part from the filter to the heat exchanger, there are few dimensional restrictions. In addition, since the dust is removed from the suction air flowing into the heat absorption part by a filter, the amount of dust contained in the condensed atomization water is small, and the transport path of the atomization water to the atomization particle generation part may be contaminated. Less.

  For this reason, the air conditioner which can always use an electrostatic atomizer in a clean state can be obtained.

  Moreover, according to the air conditioner of Claim 7, it provided in the excess dew condensation water processing water channel branched from the middle of the conveyance path which conveys the dew condensation water from the said atomization water production | generation part to the said discharge | release part, and the terminal It has excessive dew condensation water treatment means.

  As a result, even if the amount of atomized particles released is less than the generation of atomization water, the excess atomization water flows into the excess dew condensation water treatment channel, and is treated by the excess dew condensation water treatment means at the end. It does not drop or blow out with water droplets from the outlet.

  For this reason, the air conditioner which does not have a possibility that the atomization water which became excessive indoors dripping or blowing out can be obtained.

  According to the air conditioner of the eighth aspect, the excess water treatment means is a water retention material disposed on the inner surface of the outer casing.

  As a result, the excessive dew condensation water is absorbed by the water retention material, spontaneously evaporates from the surface, and does not drop out of the casing.

  For this reason, it is possible to obtain an air conditioner that has a simple structure and does not allow excessive condensed water to spontaneously evaporate and drop out of the casing.
