Description

  The present invention relates to an air conditioner having a deodorizing function.

  Conventionally, an air conditioner has been used for air conditioning (heating and dehumidification) of a room. For example, the air conditioner 1 ′ shown in FIG. 6 includes a fan 10 that sucks indoor air from the suction port 6 and blows it out from the blowout port 7 in the middle of the air blowing path 9 that connects the suction port 6 and the blowout port 7. A heat exchanger 12 that exchanges heat between the sucked room air and the refrigerant is provided, and the room air flowing through the air passage 9 is heated or cooled by the heat exchanger 12 to perform air conditioning. .

  Some of the above air conditioners have a deodorizing function. As this air conditioner, for example, an odor component is adsorbed by a filter provided in the suction port 6 shown in FIG. Some adsorb odor components by a deodorizing unit provided with a catalyst layer having an oxidative decomposition function provided in the middle of an air blowing path. However, the air conditioner having the above-mentioned deodorizing function only removes the odor component contained in the air sucked from the suction port, and does not remove the odor component contained in the air in the room. In such an air conditioner, in particular, odorous components adhering to curtains and walls could not be removed. Further, in the air conditioner, condensation is likely to occur due to the heat exchanger. Therefore, mold or the like is easily generated in the blowing path, and odor is likely to be generated. The odor component contained in the air flowing into the blowing path is removed by the filter. Even if it is removed by the deodorizing unit, there is a problem that the odor in the air flow path on the downstream side of the portion where the odor component is removed is blown into the room.

  In recent years, it is not an air conditioner, but a water reservoir, a transport unit formed by a porous member that transports water from the water reservoir, and a counter electrode unit disposed so as to face the transport direction of the transport unit And an electrostatic atomizer that applies a voltage to the water in the path from the water reservoir to the end of the transport unit in the transport direction, and the water mark of the electrostatic atomizer An active species possessed by the electrostatic mist dispersed in the room by a fan, comprising a fan that scatters electrostatic mist having a particle size of nanometer size generated when a high voltage is applied between the additional electrode part and the counter electrode part The electrostatic atomizer which removes the odor component contained in the air in the room is utilized. However, this electrostatic atomizer cannot perform air conditioning or dehumidification. Therefore, conventionally, when performing air conditioning or dehumidification and removing odor components adhering to curtains, walls, etc., the electrostatic atomizer is not compatible with the air conditioner. Since it is necessary to use both of the atomizers, there is a problem that costs are increased and a large installation space is required.

Therefore, the present inventor provided an electrostatic atomizer on the upstream side of the heat exchanger in the air flow path of the air conditioner in the process leading to the present invention, and used as a fan for sending the mist generated by the electrostatic atomizer into the room. We recalled an air conditioner with an electrostatic atomizer that also serves as a fan for the air conditioner. However, the heat exchanger of the air conditioner has a large surface area by providing fins or the like so that the contact area with the air sucked from the suction port is increased on the downstream side of the electrostatic atomizer. The mist generated by the atomizer comes into contact with the heat exchanger, which causes a problem that the mist cannot be efficiently dispersed in the room.

  The present invention has been invented in view of the above-mentioned conventional problems, and is capable of blowing out deodorized air from which odor components in the ventilation path and odor components originally contained in the room air are removed, and electrostatically. An air conditioner that can blow out air containing mist into the room and efficiently remove odorous components in the air, especially odorous components attached to curtains and walls, etc. The issue is to provide.

In order to solve the above-described problems, the air conditioner according to the present invention sucks air from the suction port 6 and blows it out from the blower port 7 in the middle of the air passage 9 that connects the suction port 6 and the long blower port 7 in the left-right direction. In the air conditioner 1 provided with the blowing means 10 and the heat exchanger 12, a water reservoir 19 (33) and a transport unit formed by a porous member that transports water from the water reservoir 19 (33). 20 (34), the counter electrode part 26a (35a) facing the end part in the transport direction of the transport part 20 (34), and the end of the transport part 20 (34) in the transport direction from the water reservoir 19 (33) And a water application electrode part 24a (36a) for applying a voltage to water in the path leading to the high voltage, and the voltage application part 27 causes a high voltage between the water application electrode part 24a (36a) and the counter electrode part 26a (35a). Applying voltage causes electrostatic atomization. And an electrostatic atomizing device 18 (32) for generating an electrostatic mist 23 having a particle size of nanometer size and containing active species, and the electrostatic atomizing device 18 (32) is connected to the heat exchanger 12 in the blower path 9.

A plurality of atomizing portions 30 (39) each composed of a counter electrode portion 26a (35a) facing the end portion in the transport direction are arranged in the longitudinal direction of the air outlet 7.

  The odor component originally contained in the room air by the electrostatic mist 23 containing the active species generated by the electrostatic atomization of the electrostatic atomizer 18 (32) and the odor component such as the mold odor attached by passing through the ventilation path 9 It is possible to deodorize the air blown out from the blow-out port 7 and to disperse the air containing the electrostatic mist 23 over the entire room by being blown by the blowing means 10. Therefore, it is possible to deodorize the room with the electrostatic mist 23 simultaneously with air conditioning, and to remove odor components in the air in the room, particularly odor components adhering to the indoor wall surface and curtains, etc. Since the electrostatic mist 23 generated in the electrostatic atomizer 18 (32) can be sent indoors by using the air blowing means 10 provided in the air conditioner, the cost is greatly increased or the size is increased. This Without it sprayed electrostatic mist 23 comprising the active species into the room. Furthermore, since the electrostatic atomizer 18 (32) is provided on the downstream side of the heat exchanger 12, the electrostatic mist 23 contained in the air blown out from the air outlet 7 flows through the air blowing path 9. Therefore, the electrostatic mist 23 generated by the electrostatic atomizer 18 can be efficiently dispersed in the room without contacting the heat exchanger 12 having a large surface area.

Further, by disposing the electrostatic atomizer 18 (32) at the downstream end of the air blowing path 9 , the electrostatic mist 23 can be dispersed more efficiently in the room.

The atomizing section 30 (39) is composed of an end portion in the transport direction of the transport section 20 (34) and a counter electrode section 26a (35a) facing the end section in the transport direction of the transport section 20 (34). By arranging a plurality of the air outlets 7 in the longitudinal direction of the air outlet 7 , the air blown out from the air outlet 7 uniformly contains the electrostatic mist 23, and the electrostatic mist 23 can be dispersed more efficiently in the room.

It is also preferable to provide the electrostatic atomizer 32 to the louvers 8. The louver 8 can disperse the electrostatic mist 23 throughout the room, and the electrostatic mist 23 included in the airflow hardly comes into contact with the louver 8, and the electrostatic mist 23 is changed regardless of the wind blowing direction changed by the louver 8. The air blowing means 10 can efficiently spray the room.

  It is also preferable to provide an air flow path 31 for returning a part of the air including the electrostatic mist 23 generated in the electrostatic atomizer 18 to the upstream side of the heat exchanger 12 in the air blowing path 9. Odor components in the heat exchanger 12 and the air flow path 9 built in the air conditioner 1 can be removed by the electrostatic mist 23 generated in the electrostatic atomizer 18.

  In the present invention, it is possible to blow out deodorized air from which the odor components in the air passage and the odor components originally contained in the room air are removed, and to blow out the air containing the electrostatic mist from the air outlet. It is possible to provide an air conditioner that can efficiently remove odorous components in a certain air, particularly odorous components adhering to curtains, walls, etc., and has a small installation space.

The heat exchanger 12 exchanges heat between the indoor air flowing into the air passage 9 from the suction port 6 and the refrigerant sent from the outdoor unit (not shown), and thereby the room flowing into the air passage 9 from the suction port 6. It cools or heats the air, and is disposed in the housing 2 along the upper portion 5 a, the upper surface portion 4, and the rear surface portion 3 of the front surface portion 5 of the housing 2.

  In addition, a drain pan 13 that is located below the heat exchanger 12 and the fan 10 and receives water condensed on the surface of the heat exchanger 12 is disposed in the housing 2. The drain pan 13 is connected to the other end of a drain hose 14 having one end communicating with the outside of the housing 2, and the drainage hose 14 allows the condensed water accumulated in the drain pan 13 to be discharged outdoors. A gap 17 is formed between the rear end of the drain pan 13 and the inner surface of the rear surface portion 3 of the housing 2 so that the upper space 15 of the drain pan 13 and the lower space 16 of the drain pan 13 in the housing 2 communicate with each other.

  The plurality of transport units 20 are arranged in a line at equal intervals in the longitudinal direction (that is, the left-right direction) of the air outlet 7. The transport unit 20 is formed of a porous member such as a porous ceramic or a porous metal alloy and has water absorption, and water in the water reservoir 19 is allowed to flow at the end on the counter electrode 26 side by capillary action. It is sucked up to a certain upper end (that is, the end in the transport direction) and transported. The transport unit 20 has a needle-like upper end, the upper part on the counter electrode 26 side projects upward from the water application electrode 24, and the lower part on the water reservoir 19 side has a lower part than the water application electrode 24. It protrudes downward and is in contact with the water to be atomized which is accommodated in the water reservoir 19.

  A rectangular and cylindrical holding portion 25 that is long in the left-right direction in a plan view is disposed so as to surround the upper portions of the plurality of conveying portions 20, and the four side wall portions of the cylindrical holding portion 25 are arranged. Among them, ventilation holes 22 are respectively formed in portions corresponding to the respective conveying portions 20 of the side wall portions (that is, the front wall portion 25a and the rear wall portion 25b) orthogonal to the blowing direction.

  Both the substantially rectangular water application electrode 24 and the counter electrode 26 that are long in the left-right direction in plan view are both made of a synthetic resin mixed with a conductive material such as carbon or a metal such as SUS. In addition, the longitudinal ends of the water application electrode 24 and the counter electrode 26 are electrically connected to a voltage application unit 27 serving as a high voltage generation source built in the housing 2.

  The water application electrode 24 is detachably attached to the upper surface of the water reservoir 19, and the user removes the electrostatic atomizer 18 from the housing 2 and removes the water application electrode 24 from the water reservoir 19 to remove water. The water stored in the reservoir 19 can be easily replenished. A plurality of circular holding hole portions 28 are formed in the water application electrode 24 in the longitudinal direction of the air outlet 7, and the holding portion 28 is held in a state where the conveying portion 20 is inserted. And in the example of illustration, the peripheral part which contact | connects the outer periphery of the intermediate part of the conveyance part 20 of each holding hole part 28 is used as the water application electrode part 24a which applies a voltage to the water in the path | route from the water reservoir part 19 to the upper end of the conveyance part 20. Yes.

  The counter electrode 26 is disposed above the transport unit 20, and the counter electrode 26 penetrates up and down at a position facing the upper end of each transport unit 20 (that is, the end in the transport direction) and holds the holding unit 27. A circular opening 29 for communicating the inside and the air passage 9 is formed. The circular openings 29 are provided side by side in the longitudinal direction of the air outlet 7. In the illustrated example, each circular opening 29 is used as a counter electrode part 26 a. In other words, a plurality of atomizing sections 30 composed of the upper end portion of the transport section 20 and the counter electrode section 26 a facing the upper end section of the transport section 20 are arranged in the longitudinal direction of the air outlet 7. Are arranged in a line at equal intervals. In addition, the front-end | tip of the needle-like part 20a which is an upper end part of the conveyance part 20 shall be located in the center of the counter electrode part 26a seeing from upper direction.

  Then, the transport unit 20 sucks up the water by capillary action, and further, the voltage application unit 27 applies a high voltage that can cause Rayleigh splitting to the counter electrode 26 and the water application electrode 24. The water that has reached 20 needle-like parts 20a undergoes Rayleigh splitting at the tip of the needle-like part 20a to cause electrostatic mist 23, and the electrostatic mist 23 produced by this electrostatic atomization is From each counter electrode part 26a of the electrostatic atomizer 18, it blows out toward the ventilation path 9. That is, when a high voltage is applied between the water application electrode 24 and the counter electrode 26 by the voltage application unit 27 and the conveyance unit 20 sucks up water by capillary action, the tip of the needle-like portion 20a of the conveyance unit 20 is the water application electrode. It functions as a substantial electrode on the 24 side, and at the same time, the peripheral edge portion of each holding hole 28 (counter electrode portion 26a) functions as a substantial electrode on the counter electrode 26 side. Here, it is preferable that the voltage application unit 27 provides an electrolytic strength of 500 V / mm or more between the water application electrode unit 24a and the counter electrode 26a.

  When performing indoor deodorization using the air conditioner 1 equipped with the electrostatic atomizer 18, the fan 10 is operated and, as described above, between the water application electrode unit 24a and the counter electrode unit 26a by the voltage application unit 27. A high voltage is applied to the electrostatic atomizer 18 to operate it. As a result, the odor components in the air passage 9 and the odor components originally contained in the indoor air are removed from the air blown from the outlet 7 by the electrostatic mist 23 having active species generated by electrostatic atomization. The electrostatic mist 23 having the active species generated by the electrostatic atomization can be dispersed throughout the room by being blown by the fan 10, and the electrostatic mist 23 has an active species. It is possible to remove odor components in the air in the room, particularly odor components adhering to the wall surface of the room, curtains and the like, and furthermore, air conditioning can be performed simultaneously with the removal of the odor components. Thus, since the air conditioner 1 of this embodiment can send the electrostatic mist 23 produced in the electrostatic atomizer 18 indoors using the fan 10 with which the air conditioner is equipped conventionally, it is large. It is possible to remove indoor odor components without increasing the cost or increasing the size.

  In the air conditioner 1 described above, since the electrostatic atomizer 18 is disposed downstream of the heat exchanger 12, the electrostatic mist 23 that flows through the blowing path 9 by the blowing of the fan 10 is generated. Without contact with the heat exchanger 12 whose surface area is increased by fins or the like, the electrostatic mist 23 generated by the electrostatic atomizer 18 can be efficiently dispersed indoors. Moreover, since the electrostatic atomizer 18 is arrange | positioned in the downstream edge part which is the blower outlet 7 vicinity of the ventilation path 9 as mentioned above, electrostatic mist 23 can be spread | dispersed indoors still more efficiently. Yes. Further, as described above, the atomizing unit 30 constituted by the upper end portion (needle-like portion 20a) of the transport unit 20 and the counter electrode unit 26a arranged so as to face the transport direction of the transport unit 20 is blown out. 7 is arranged in the longitudinal direction, the electrostatic mist 23 is uniformly contained in the air blown out from the air outlet 7, and the electrostatic mist 23 can be more efficiently dispersed throughout the room. Further, as described above, since the ventilation hole 22 is formed in the peripheral surface portion of the holding portion 25 of the electrostatic atomizer 18, the electrostatic mist 23 in the holding portion 25 can be put on the air blown by the fan 10. it can.

  Next, an embodiment different from the above embodiment will be described. In addition, the same number is provided about the structure same as embodiment of FIG. 1, and description is abbreviate | omitted about the overlapping description.

  In the present embodiment, as shown in FIG. 3, an air flow path 31 is provided to return a part of the air including the electrostatic mist 23 generated in the electrostatic atomizer 18 to the upstream side of the heat exchanger 12 in the blowing path 9. Yes. The air flow path 31 is constituted by a pipe, and one end of the air flow path 31 is directly above the counter electrode portion 26a of the electrostatic atomizer 18 in the air blowing path 9 (that is, from the electrostatic atomizer 18 to the electrostatic mist). The other end of the air flow path 31 communicates with the downstream side of the air purifying filter 11 and the upstream side of the heat exchanger 12. Thus, when the fan 10 is operated and the electrostatic atomizer 18 is operated, the electrostatic mist 23 sprayed from the electrostatic atomizer 18 rides on the air sent by the fan 10, and then the Part of the air including the electrostatic mist 23 flows into the upstream side of the heat exchanger 12 in the air passage 9 through the air flow path 31, and the rest is blown out from the air outlet 7 without passing through the air flow path 31. . Here, part of the air returned to the upstream side of the heat exchanger 12 by the air flow path 31 immediately passes through the heat exchanger 12 and is then sent to the downstream side of the fan 10. Thus, by returning a part of the air including the electrostatic mist 23 generated in the electrostatic atomizer 18 to the upstream side of the heat exchanger 12 by the air flow path 31, the electrostatic mist 23 contained in the air It is possible to remove odor components in the heat exchanger 12 and the air passage 9 installed in the air conditioner 1.

  Next, an embodiment different from the above embodiment will be described. In this embodiment, as shown in FIG. 4, the electrostatic atomizer 32 is provided in the horizontal louver 8 in the embodiment of FIG. 1, and the same configuration as that of the embodiment of FIG. Numbers are given, and descriptions of overlapping descriptions are omitted.

  The horizontal louver 8 of this embodiment is composed of an electrostatic atomizer 32, and the electrostatic atomizer 32 will be described below. In the following description of the electrostatic atomizer 32, the blowing direction of the wind blown from the outlet 7 with the horizontal louver 8 (that is, the electrostatic atomizer 32) turned in a vertical plane in a horizontal position. In the following description, the horizontal direction of the horizontal louver 8 is defined as the vertical direction.

  As in the embodiment of FIG. 1, the electrostatic atomizer 32 includes a water reservoir 33 that stores water to be atomized and a vertically long rod-shaped transport unit that transports water in the water reservoir 33. 34, a counter electrode part 35a facing the end part in the transport direction of the transport part 34, and a water application electrode part 36a for applying a voltage to the water in the path from the water reservoir 33 to the end in the transport direction of the transport part 34 And.

  More specifically, the electrostatic atomizer 32 is formed of an insulator and has a shallow container 37 that is long in the left-right direction and opens upward, and an excellent water absorption property such as felt disposed in the container 37. The water reservoir 33 made of a water-absorbing body, a piece of water application electrode 36 held on the outer peripheral wall of the container 37, a plurality of the transporting parts 34 standing on the bottom plate of the container 37, and a container The outer surface of the electrostatic atomizer 32 composed of the container 37 and the counter electrode 35 is formed in a box shape that is long in the left-right direction. I am doing. And the electrostatic atomizer 1 is attached to the opening provided in the lower part 5b of the front part 5 of the housing | casing 2 so that rotation is possible, and the electrostatic atomizer 1 winds from the blower outlet 7. It functions as a horizontal louver 8 that changes the blowing direction of.

  The plurality of transport units 34 are erected in a row at equal intervals in the longitudinal direction (that is, left-right direction) of the air outlet 7 on the bottom surface of the container 37. The transport unit 34 is formed of a porous member such as a porous ceramic or a porous metal alloy so as to absorb water, and the water in the water reservoir 33 is absorbed at the end on the counter electrode 35 side by capillary action. It is sucked up to a certain upper end (that is, the end in the transport direction) and transported. The upper end of the transport part 34 is pointed like a needle, and the lower part, which is a part on the side of the water reservoir 33, is in contact with the water absorbed by the water reservoir 33.

The strip-shaped water application electrode 36 and the substantially rectangular counter electrode 35 that is long in the left-right direction in plan view are made of a synthetic resin mixed with a conductive material such as carbon or a metal such as SUS. In addition, one end of the counter electrode 35 in the left-right direction and the end of the water application electrode 36 that protrudes outward from the outer peripheral wall of the container 37 are both electrically connected to the voltage application unit 27.

  The counter electrode 35 is positioned higher than the plurality of transport units 34, and the counter electrode 35 is provided with a circular opening 38 penetrating vertically at a position facing the upper end of each transport unit 34. . The circular openings 38 are arranged side by side in the longitudinal direction of the air outlet 7, and in the example shown in the drawing, these circular openings 38 serve as counter electrode portions 35 a. That is, in this example as well, the atomizing portion 39 composed of the end portion (the needle-like portion 34a) of the transport portion 34 in the transport direction and the counter electrode portion 35a facing the end portion of the transport portion 34 in the transport direction is provided as the air outlet 7. A plurality of these atomizing portions 39 are arranged in a line at equal intervals. Also in this example, it is assumed that the tip of the needle-like portion 34a, which is the end portion in the carrying direction of the carrying portion 34, is located at the center of the circular opening 38 as viewed from above. The counter electrode 35 may be detachably attached to the end face on the opening side of the container 37 so that water can be supplied to the water reservoir 33 made of a water absorbent.

  The end of the water application electrode 36 opposite to the side connected to the voltage application unit 27 protrudes inward from the outer peripheral wall of the container 37 and is in contact with the water absorbed by the water reservoir 33. In other words, in this example, the end of the water application electrode 36 in contact with the water reservoir 33 is a water application electrode portion 36a.

  Then, as in the embodiment of FIG. 1 described above, by applying a high voltage to the counter electrode 35 and the water application electrode 36 by the voltage application unit 27, the water that has reached the needle-like portion 34a of the transport portion 34 is Electrostatic atomization that causes Rayleigh splitting at the tip to generate an electrostatic mist 23 is performed, and the electrostatic mist 23 generated by the electrostatic atomization is each counter electrode portion arranged on the upper portion of the electrostatic atomizer 32. It is blown upward from 35a and sprayed in the space formed between the horizontal louvers 8, 8 adjacent vertically.

The air is blown upward from the counter electrode portion 35a, and then blown from the blower outlet 7 (blow hole 7a) along with the air blown from the fan 10 flowing between the horizontal louvers 8, whereby the electrostatic mist 23 is blown out. 7, it becomes difficult to contact the horizontal louver 8 when being blown out, and the electrostatic mist 23 can be efficiently sprayed indoors by the fan 10 regardless of the blowing direction of the wind changed by the horizontal louver 8. Moreover, since the water reservoir 33 of the electrostatic atomizer 32 according to the present embodiment is constituted by a water absorbent, the blowing direction of the wind blown from the outlet 7 by the electrostatic atomizer 32 constituting the horizontal louver 8. When the electrostatic atomizer 32 is tilted with respect to the horizontal when changing, the water that will be atomized from the container 37 can be prevented from spilling.
