Description

  The present invention relates to a configuration of an air conditioner that performs sterilization, deodorization, and removal of harmful substances by discharging water fine particles (water clusters) having high oxidizing power into a room.

  Recent air conditioners are not limited to cooling and heating, but are provided with various functions such as removal of floating dust and allergen, deodorization, and antibacterial in order to improve the quality of indoor air. However, basically, as these means, various types of filters are provided at the air suction port and filtered or adsorbed. When the contamination of these filters progresses, the ventilation resistance increases and air conditioning is increased. Not only does energy consumption increase, but dust and odor accumulate on the filter if not properly cleaned and cared for, which may have the opposite effect.

  In addition, when deodorizing by the above method, the odorous component in the indoor air is removed relatively quickly, but the odorous component adhering to the indoor walls and curtains cannot be removed. Had the problem that the odor remained.

  On the other hand, for example, by mixing an appropriate amount of deodorizing and sterilizing gas with cold / warm air blown out from the inside of air conditioners as shown in FIG. 6, generation of bad odors, bacteria, bacteria, moss, etc. An air conditioner equipped with a deodorizing and sterilizing gas supply means that can prevent diffusion is invented (see, for example, Patent Document 1).

  In this conventional example, as shown in FIG. 6, a deodorizing and sterilizing gas supply means 110 having a drug container 112 and a vaporization promoting part 114 that performs a vaporization promoting action on the drug container 112 is provided in an air flow path. Air conditioners equipped with a deodorizing and sterilizing gas supply means disposed in part. Examples of applicable chemicals include formalin and cresol. Stabilized chlorine dioxide is particularly excellent in sterilizing and deodorizing properties. It is said to be safe for handling.

  The deodorizing and sterilizing gas supply means 110 is desirably disposed in an air flow path between the air intake port 1 of the air conditioner and the heat exchanger (cold / warm air forming section) 2.

  With such a configuration, due to the vaporization promoting action of the vaporization promoting unit 114, chlorine dioxide is vaporized from the stabilized chlorine dioxide stored in the drug container 112 in an appropriate amount, and the chlorine dioxide gas thus obtained can be various. The appropriate amount of cold air or heat that is exchanged from the heat source or the heat source is mixed in an appropriate amount, and then sequentially passes through the inside of the air conditioner equipment, the duct, etc., and the room as the air conditioning target space from the air outlet 4 of the air conditioner etc. Is blown out.

Thus, cold / warm air mixed with deodorizing and sterilizing gas is blown into the room, and the atmosphere in the applied room can be maintained in a clean and safe state.

  However, the conventional configuration assumes the use of a chemical substance such as chlorine dioxide as a deodorizing and sterilizing gas. Especially when it is widely used for home use, if the management of the release amount becomes insufficient, it is completely safe. However, there were problems such as odor in the released substance itself.

The present invention solves the above-described conventional problems, generates highly safe and highly oxidizing water fine particles efficiently and stably, and even to odor components adhering to indoor walls and curtains. It is an object of the present invention to provide an air conditioner having a function that can be removed, and a function that can inactivate allergens, viruses, etc., and sterilize mold, bacteria, and the like.

  In order to solve the above-mentioned conventional problems, a heat exchanger, a blower, a blower circuit extending from the suction port through the heat exchanger, the blower to the blowout port, and a Peltier element, on the cooling surface side A water cluster generator that discharges the generated water into the air as fine water particles containing radicals and ions with high oxidizing power by discharge of the discharge electrode, the cooling surface of the water cluster generator and the discharge electrode The discharge electrode is placed outside the air outlet and the discharge electrode is placed in the vicinity of the air outlet, and the discharged water fine particles are attracted to the air blow and discharged into the room.

  As a result, water particles with high oxidizing power regardless of the operating condition of the air conditioner are spread on the air blower of the air conditioner and diffused in the room to remove odorous components adhering to the walls and curtains in the room. High performance is exhibited against inactivation of allergens and viruses floating or adhering in the room and sterilization of molds, bacteria, and the like. Moreover, since the discharge | release component is water, high safety | security is ensured. Furthermore, since the cooling surface and the discharge electrode of the water cluster generator are outside the air outlet, that is, outside the air passage, the air temperature is low even during heating, and since the air speed is slow because it is outside the air passage, the cooling surface is easily provided. Condensation can occur. In addition, since the cooling surface and the discharge electrode are in the vicinity of the outlet, the discharged water fine particles are attracted by the blowing air and diffused widely in the room.

  The present invention can remove even odorous components adhering to indoor walls and curtains, etc., and has an air conditioning function that can inactivate allergens, viruses, etc. that are floating or adhering in the room and sterilize mold, bacteria, etc. Machine can be provided.

  The first invention has a heat exchanger, a blower, a blower circuit from the suction port through the heat exchanger, the blower to the outlet, and a Peltier element, and water generated on the cooling surface side A water cluster generator for discharging into the air as fine water particles containing radicals and ions with high oxidizing power by discharge of the discharge electrode, the cooling surface of the water cluster generator and the discharge electrode being connected to the outlet The discharge electrode is placed in the vicinity of the outlet, and the discharged water fine particles are attracted to the blow-off air and released into the room. Removes odorous components adhering to indoor walls and curtains by riding in the wind, and also inactivates allergens, viruses, etc. floating or adhering to indoors and sterilizing mold, bacteria, etc. High Performance is exhibited, also, high safety is ensured. Furthermore, because the cooling surface and discharge electrode of the cluster generator are outside the air outlet, that is, outside the air passage, the air temperature is low even during heating, and the air speed is slow because it is outside the air passage, so condensation easily forms on the cooling surface. In addition, since the cooling surface and the discharge electrode are in the vicinity of the outlet, the discharged water fine particles can be attracted by the outlet air and diffused widely in the room.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a longitudinal sectional view of an air conditioner indoor unit according to a first embodiment of the present invention, FIG. 2 is a front view of a blower outlet, and FIG. 3 is an enlarged perspective view of a water cluster generator to be attached. FIG. 4 is a longitudinal sectional view of the water cluster generator, and FIG. 5 is a graph showing a deodorizing effect by water fine particles.

  1 and 2, there is a blower circuit from the suction port 1 through the heat exchanger 2 and the blower 3 to the blowout port 4, and the water cluster generator 5 is fixed inside the right side of the blowout port 4.

  3 to 4, the water cluster generating device 5 has a Peltier element 6, which contacts the cooling surface side 7 of the discharge electrode 8 and contacts the heat dissipation surface side 9 and fixes the radiation fins 10. Further, a ground electrode 11 is provided on the opposite side of the discharge electrode, and a high voltage is applied between both electrodes.

  In addition, an opening 12 is provided near the lower portion of the water cluster generator 5, and an air passage 13 is provided to allow the air sucked and attracted to the blower 3 from the opening 12 to the heat radiating fins 10 of the water cluster generator 5 only.

  About the air conditioner indoor unit comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the Peltier element 6 is energized, a temperature difference occurs between the two surfaces. In this case, if the cooling amount on the cooling surface in contact with the cooling surface side 7 and the heat radiation amount from the radiation fin 10 in contact with the heat radiation surface side 9 are appropriately designed, dew condensation occurs on the discharge electrode 8 thereon.

  Here, when a high voltage is applied to the discharge electrode 8 and the ground electrode 11, a discharge occurs, and fine water particles (clusters) having a diameter of about 18 nm are discharged (the diameter and amount of water particles are high voltage). Therefore, the application amount and the input of the Peltier element are adjusted so that the most effective particle size and the amount of discharge are increased.)

  These water fine particles have high reactivity, and have the ability to act on odorous components and decompose them into odorless components. The effect is shown in FIG. Here, a cigarette odor was attached to the curtain fabric, and after 2 hours, the difference in odor attenuation due to the presence or absence of water cluster release was evaluated by a sensory test (6-step odor display method). The effect is clearly seen compared to the case of.

  In addition, since this water cluster has high safety and high oxidizing power, it is highly effective against inactivation of allergens, viruses, etc. floating or adhering to the room and sterilization of molds, bacteria, etc.

  Moreover, since the air temperature in the blower outlet 4 is high at the time of heating, and normally the absolute humidity is lowered, the cooling surface 7 and the discharge electrode 8 are placed in the blower outlet 4. It is not easy to lower the temperature of the discharge electrode 8 below the dew point. However, by placing the cooling surface 7 and the discharge electrode 8 outside the outlet 4 as in the present invention, the air temperature is low and the wind speed is slow because it is outside the air passage, so that condensation can easily occur on the cooling surface 8. it can. Furthermore, by placing the cooling surface 7 and the discharge electrode 8 in the vicinity of the outlet 4, the discharged water fine particles are attracted by the blowing air and can be diffused widely in the room.

  Further, unlike the blowout air whose temperature changes due to cooling or heating operation, the air in the air-conditioned room having a relatively stable temperature is passed from the opening 12 through the ventilation path 13 only to the heat radiating fins 10. The heat dissipating fins 10 can be radiated efficiently and stably. Therefore, dew condensation is possible with low input without increasing the input to the Peltier element 6, dew condensation on the discharge electrode 8 is stable, the discharge state is stable, and water fine particles having high oxidizing power are stably generated. be able to.

Moreover, as shown to FIGS. 3-4, the length of the ventilation path 13 becomes short by providing the opening part 12 which sucks air into the ventilation path 13 in the vicinity of the water cluster generator 5, and the sucked air becomes ventilation path Since the air is passed through the heat radiating fin 10 with almost no reduction in the wind speed at 13, the heat radiation can be promoted, the temperature of the cooling surface 7 can be lowered efficiently, and the input to the Peltier element 6 required for dew condensation can be reduced.

  Furthermore, the opening 12 is arranged in the lower part of the water cluster generator 5 and the heat radiating fins 10 have parallel fins arranged in the vertical direction so that the air heated by the heat radiating fins 10 is accompanied by a rising airflow. Since the air sucked from the opening 12 below the heat radiating fin 10 easily flows upward and the wind speed increases, the heat radiation of the heat radiating fin 10 is promoted. Thus, the temperature of the cooling surface 7 can be lowered efficiently, and the input to the Peltier element 6 required for dew condensation can be lowered. The position of the opening 12 is not limited to the above, and the opening is arranged so that the ventilation to the radiation fins is optimized according to the installation mode of the air conditioner and the internal structure.

  In addition, as shown in FIG. 4, the water cluster generating device 5 provides a partition so that there is no air communication between the space where the discharge electrode 8 is provided and the ventilation path 13, thereby generating water generated from the discharge electrode 8. Since the fine particles are not attracted to the air passage 13 and are attracted to the blown air, they are put on the blown air while maintaining a strong oxidizing power without reducing the oxidizing power in the air blowing path until it is released indoors. Can be diffused indoors.

  As described above, the air conditioner according to the present invention is not limited to the wall-mounted indoor unit of a general residential air conditioner, but has various forms such as an air conditioner for a large space such as an office. It can also be widely applied as an air purifying function of other air conditioners.
