JP 2005-131549 A

  However, in the configuration using the blower fan described in Patent Document 1, it is necessary to use a large blower fan in order to obtain a predetermined air volume, and the structure is complicated and the entire apparatus is enlarged. was there.

  In particular, when used in a vehicle air conditioner, the space for installing the electrostatic fine particle water generator is limited, and thus there is a great need for downsizing the device.

  Then, this invention aims at providing the vehicle air conditioner provided with the electrostatic fine particle water generator which does not require a dedicated ventilation fan.

  In order to achieve the above object, an air conditioner for a vehicle according to the present invention includes an air conditioning unit having a heat exchanger, a blower for sending air to the air conditioning unit, and a duct for introducing air that has passed through the air conditioning unit into a vehicle interior. An air conditioner for a vehicle comprising an electrostatic fine particle water generator, wherein a housing portion is attached to an opening provided in a wall surface of the duct, and the housing portion is connected to the upstream side of the duct. It has an outlet and a discharge port communicating with the downstream side, and an electrostatic fine particle water generating part of the electrostatic fine particle water generator is arranged inside the housing part.

  Here, the electrostatic fine particle water generation unit is disposed in a detour that connects the intake port and the discharge port, and moisture in the air is added to the electrostatic fine particle water generation unit inside the duct. The heat radiation fins of the thermoelectric conversion elements that supply the heat can be arranged.

  In addition, the housing part includes a venturi path that allows the intake port and the discharge port to communicate with each other via a narrow portion, and a generation path and a heat dissipation path that take in air from a location different from the opening. In the generation path, the electrostatic fine particle water generation unit is disposed and the downstream side thereof is connected to the vicinity of the narrow portion of the venturi path, and the heat dissipation path is connected to the electrostatic fine particle water generation unit in the air. A heat dissipation fin of a thermoelectric conversion element that supplies moisture may be disposed and a downstream side thereof may be communicated with the inside of the duct.

  The vehicle air conditioner of the present invention configured as described above has a housing portion mounted in an opening provided on a wall surface of a duct, and the electrostatic fine particle water generating portion of the electrostatic fine particle water generating device inside the housing portion. Is placed.

  And since this housing part has an intake port and a discharge port communicating with the upstream side and the downstream side of the duct, the flow and pressure difference of the air can be used, without providing a dedicated blower fan, Electrostatic fine particle water can be discharged into the duct.

  In addition, the electrostatic particulate water generator can be easily assembled by mounting the housing portion in which the electrostatic particulate water generating portion is disposed in the opening of the duct.

  Furthermore, if the electrostatic fine particle water generation part is arranged in a detour that communicates the intake port and the discharge port, and the heat dissipating fin is arranged inside the duct, the inside of the duct can be provided without providing a dedicated blower fan. The radiating fin can be efficiently cooled by the flowing air.

  In another form of vehicle air conditioner, the air flowing inside the duct is taken in from the intake port to form a flow in the venturi path. On the other hand, air is taken in from a place other than the opening of the duct, and the air flows through a generation path where the electrostatic fine particle water generation unit is arranged and a heat dissipation path where the radiation fins are arranged.

  By connecting the generation path to this venturi path, it is possible to form an air flow in an amount necessary for discharging electrostatic fine particle water without being greatly affected by the wind speed and static pressure inside the duct. it can.

  Further, if the air flowing from the portion other than the opening of the duct to the generation path and the heat dissipation path is secured, the air volume can be secured without being influenced by the wind speed or static pressure inside the duct. Furthermore, it is possible to flow air containing a lot of moisture that easily generates dew condensation water through the generation path.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  First, the structure of the vehicle air conditioner 1 of this Embodiment is demonstrated using FIG.

Side vent ducts 41 and 41 and center vent ducts 42 and 42 are provided as ducts for releasing heated and cooled air into the passenger compartment.

  The blower 3 includes an inside / outside air introduction section (not shown) for introducing air inside and outside the vehicle interior, a filter (not shown) for filtering air, and a blower blade (not shown). Since it is a sirocco fan type, in addition to ensuring a high static pressure when blowing air, there is a feature that a certain amount of blowing air can be secured even when a high static pressure is applied.

  Moreover, as shown in FIG. 5, the evaporator 21 and the heater 22 are arrange | positioned inside the air-conditioning unit 2 as a heat exchanger, the air ventilated from the air blower 3 is cooled and heated, and it mixes with a mix chamber. Thus, the air can be adjusted to an optimum temperature and blown to the passenger compartment side.

  Further, as shown in FIG. 2, the side vent ducts 41 and 41 and the center vent ducts 42 and 42 can efficiently introduce the air adjusted to the optimum temperature by the air conditioning unit 2 into the vehicle interior. The air outlet of the air conditioning unit 2 is connected to the vehicle interior, and has a predetermined cross-sectional area and a smooth inner surface.

  As shown in FIGS. 1 and 2, in the vehicle air conditioner 1 of the present embodiment, an opening 41a is provided on the upper wall surface of one side vent duct 41, and the electrostatic fine particle water generator is provided in the opening 41a. A housing part 5 to which 6 is attached is mounted.

  The housing portion 5 is formed in substantially the same shape as the plan view of the opening portion 41a so that the lower end fits into the opening portion 41a, and a flange portion 55 is projected around the lower end to project the opening portion 41a. It is configured to be engaged around. By mounting the housing part 5, the opening 41a of the side vent duct 41 is closed.

  Further, as shown in FIG. 1, the housing portion 5 is formed with a bypass 51 that meanders and connects the intake port 52 and the discharge port 53.

  The intake port 52 protrudes into the side vent duct 41 and opens toward the upstream side (air conditioning unit 2 side), and the opening surface has a direction in which the air inside the side vent duct 41 flows (FIG. 1). In the direction of white arrow).

  Further, the discharge port 53 opens toward the center of the cross section of the side vent duct 41, and the opening surface is substantially parallel to the direction in which the air inside the side vent duct 41 flows (the white arrow direction in FIG. 1). .

  Further, for example, as shown in FIG. 1, the bypass 51 extends and bends outward from the intake port 52 toward the outside of the side vent duct 41, and extends substantially parallel to the extending direction of the side vent duct 41. Later, it is bent at the mounting opening 54 of the electrostatic fine particle water generator 6 to be described later, is extended outward again, and is turned back toward the discharge opening 53.

  A mounting port 54 provided in the middle of the detour 51 is formed with an opening for communicating the inside of the side vent duct 41 and the detour 51, and is used for mounting the electrostatic fine particle water generator 6. The

  As shown in FIG. 3, the electrostatic fine particle water generator 6 supplies electrostatic fine particle water generation unit 61 that generates electrostatic fine particle water M, and supplies moisture in the air to the electrostatic fine particle water generation unit 61. It is mainly composed of a Peltier element 62 as a thermoelectric conversion element, a heat radiation fin 63 that cools the Peltier element 62, and an insulating plate 64 that closes the mounting opening 54.

  The electrostatic fine particle water generating unit 61 includes a plate-like discharge electrode 61a, a water transport unit 61b protruding from the discharge electrode 61a, and a counter electrode 61c disposed at a position spaced from the tip of the water transport unit 61b. And is composed mainly of.

  The discharge electrode 61 a is formed in a rectangular shape in plan view with a metal such as aluminum and is disposed on the upper surface side of the insulating plate 64.

  In addition, the water transport unit 61b is formed in a conical shape using a porous material such as ceramic so that the condensed water moves to the tip by capillary action, and is protruded substantially at the center of the discharge electrode 61a. Yes.

  Further, the counter electrode 61c is processed into an annular plate shape having holes concentrically formed of metal or the like.

  The discharge electrode 61a and the counter electrode 61c are connected to a high voltage application unit 71 that is supplied with power from the power supply control unit 7, and a high voltage is applied so that the discharge electrode 61a side becomes a negative electrode.

  A Peltier element 62 having substantially the same shape as that of the discharge electrode 61a is provided in contact with the back surface of the discharge electrode 61a, and a heat radiating fin 63 is attached to the back surface of the Peltier element 62.

This Peltier element 62 is formed in a plate shape by joining two kinds of metals. When a current is supplied from the power supply control unit 7 to the joint of the two kinds of metals, heat is transferred from one metal to the other. This is a plate-like semiconductor element that utilizes the Peltier effect of moving, and in this embodiment, the side that contacts the discharge electrode 61a is a heat absorbing part, and the side that contacts the heat radiating fin 63 is a heat radiating part.

  Further, the insulating plate 64 is provided with a rectangular opening that accommodates the Peltier element 62 and communicates the discharge electrode 61a side and the radiation fin 63 side.

  On the other hand, the radiating fin 63 is formed of a metal such as aluminum, and as shown in FIG. 3, a plurality of thin plate-like wings are projected substantially in parallel on one side of the plate-like base. The surface area is increased so that heat can be exchanged efficiently.

  In order to uniformly blow air to each of the thin plate-like wings, the radiating fins 63 have the wing surfaces parallel to the air flow direction as shown in FIG. Project toward the inside.

  On the other hand, when the radiating fin 63 is attached to the mounting port 54 in such a direction, the electrostatic fine particle water generating unit 61 is projected inside the detour 51.

  A part of the air flowing inside the side vent duct 41 is taken in from the intake port 52 of the bypass 51 and supplied to the electrostatic fine particle water generation unit 61, and the electrostatic fine particle water M generated there At the same time, the electrostatic fine particle water M is discharged into the side vent duct 41 by being carried to the discharge port 53.

  Next, the effect | action of the vehicle air conditioner 1 of this Embodiment is demonstrated.

  As shown in FIG. 1, the vehicle air conditioner 1 of the present embodiment configured as described above has a housing portion 5 mounted in an opening 41 a provided on the upper wall surface of the side vent duct 41, and the housing portion The electrostatic fine particle water generation unit 61 of the electrostatic fine particle water generator 6 is disposed inside the detour path 51 of the fifth.

  And since this housing part 5 has the intake port 52 and the discharge port 53 which are connected to the upstream and downstream of the side vent duct 41, respectively, the flow of air flowing inside the side vent duct 41 and The pressure difference between the intake port 52 and the discharge port 53 can be used to take air into the bypass 51.

  For this reason, without providing a dedicated blower fan, the electrostatic fine particle water M can be discharged into the side vent duct 41 and the electrostatic fine particle water M can be discharged from there into the vehicle interior.

  That is, when air is taken in from the intake port 52, an air flow is formed along the detour 51 to the discharge port 53.

  This bypass 51 is meandering, and air flows at a speed different from the wind speed inside the side vent duct 41.

  Then, air containing moisture flows into the electrostatic fine particle water generation unit 61 and passes through the central hole of the counter electrode 61c. At this time, between the water transport unit 61b and the counter electrode 61c, The electrostatic fine particle water M sprayed in the form of mist is mixed.

  Since the bypass 51 is formed with a one-way air flow, the passing air does not stay or flow backward, and the electrostatic fine particle water M sprayed in a mist form from the water transport section 61b. Can be attracted efficiently.

  Here, the generation mechanism of the electrostatic fine particle water M will be schematically described.

  First, as shown in FIG. 3, when the Peltier element 62 is energized, the surface of the Peltier element 62 facing the discharge electrode 61a is cooled, and the discharge electrode 61a that is in contact with the Peltier element 62 is cooled. Condensed water is generated on the surface of the electrode 61a.

  This condensed water is transported by capillary action from the root portion to the tip end portion of the water transport portion 61b protruding from the discharge electrode 61a.

  The condensed water transported to the tip of the water transport 61b is directed from the sharp tip of the water transport 61b toward the counter electrode 61c by a high voltage applied between the discharge electrode 61a and the counter electrode 61c. Are ejected to become electrostatic fine particle water M.

  Here, in order to generate this dew condensation water, heat is radiated by the radiation fins 63 provided in contact with the back surface of the Peltier element 62. As shown in FIG. Since it protrudes inside 41, the air volume required for cooling the heat radiation fin 63 can be obtained without providing a dedicated blower fan.

  That is, since the heat radiation fin 63 protrudes from the opening 41a of the side vent duct 41 toward the inside, a sufficient amount of air can be blown to the heat radiation fin 63, so that air does not stay or flow backward. It becomes possible to dissipate heat efficiently.

  And since the heat radiation of the Peltier element 62 is accelerated | stimulated through the heat dissipation surface of the Peltier element 62 which contacts the front side of this heat radiation fin 63 by cooling the radiation fin 63, heat exchange can be performed efficiently.

  The air containing the electrostatic fine particle water M as described above is discharged into the side vent duct 41 from the discharge port 53 of the bypass 51 as shown in FIG.

  And the air discharged | emitted by the side vent duct 41 will be finally discharge | released by the vehicle interior, and will disinfect and deodorize the vehicle interior.

  Since the electrostatic fine particle water M discharged from the electrostatic fine particle water generator 6 is less attenuated with the passage of time, the electrostatic fine particle water M discharged from the outlet of the side vent duct 41 into the vehicle interior is used as the entire vehicle interior. Can diffuse.

  Moreover, if the electrostatic fine particle water generator 6 is arrange | positioned in the duct close | similar to a vehicle interior like the side vent duct 41, the attenuation | damping inside the vehicle air conditioner 1 can be suppressed to the minimum.

  Furthermore, if it is the structure which attaches the housing part 5 directly to the opening part 41a of ducts, such as the side vent duct 41, it can be easily assembled | attached to a vehicle air conditioner of various forms, hardly changing. it can.

  That is, if the electrostatic fine particle water generating device 6 is attached to the mounting opening 54 of the housing part 5, the electrostatic fine particle can be simply attached to the opening 41 a opened on the upper wall surface of the side vent duct 41. The arrangement of the water generator 6 is completed.

  Thus, in the vehicle air conditioner 1 of the present embodiment, it is possible to obtain an air volume and a wind speed sufficient for discharging the electrostatic fine particle water M with a simple configuration without providing a dedicated blower fan.

  Moreover, since the housing part 5 is arrange | positioned outside the side vent duct 41, there are few restrictions with respect to a shape, and it can employ | adopt the shape which is easy to shape | mold.

  Hereinafter, a vehicle air conditioner 1 </ b> A of a form different from the above embodiment will be described using FIGS. 4 and 5. The description of the same or equivalent parts as those described in the above embodiment will be given the same reference numerals.

  In this example, the case where not only the air flowing inside the side vent duct 41 is used as in the above-described embodiment but also the air is taken in from other locations and used will be described.

  As shown in FIG. 5, the vehicle air conditioner 1 </ b> A according to this embodiment is heated by the air blower 3, the air conditioning unit 2 including the heat exchanger that heats and cools the air blown from the blower 3, and the air conditioning unit 2. And a duct 4 such as a side vent duct or a center vent duct that discharges the cooled air into the vehicle interior.

  Inside the air conditioning unit 2, an evaporator 21 and a heater 22 are arranged. The air blown from the blower 3 is cooled and heated, and mixed in a mix chamber to adjust the air to an optimum temperature. The air can be blown into the room.

  On the other hand, an opening 4a as shown in FIG. 4 is provided on the wall surface of the duct 4, and a housing 8 having an electrostatic fine particle water generator 6 attached to the opening 4a is mounted.

  The housing portion 8 of this embodiment is formed in substantially the same shape as the plan view of the opening portion 4a so that the lower end fits into the opening portion 4a, and a flange portion 87 is projected around the lower end to open the opening portion 4a. It is configured to be engaged around the portion 4a.

  As shown in FIG. 4, a venturi path 81 that connects the intake port 82 and the discharge port 83 is formed in the housing portion 8.

  The venturi path 81 is formed with a narrow portion 81a having a smaller cross section than the cross section of the intake port 82 and the discharge port 83 at both ends of the flow path, and is faster than the wind speed when taken in at the intake port 82. The wind speed when passing through the narrow part 81a becomes faster, and the pressure of the narrow part 81a becomes lower from Bernoulli's theorem.

  On the other hand, the surface of the housing portion 8 corresponding to the downstream side of the air flow in the duct 4 is opened to take in air from a location different from the opening 4a.

  In this opening, a generation path 84 in which the electrostatic fine particle water generation unit 61 is disposed, and a heat dissipation path 85 in which the heat dissipation fins 63 of the Peltier element 62 that supplies moisture in the air to the electrostatic fine particle water generation unit 61 are disposed. And communicated with each other.

  The generation path 84 extends substantially parallel to the extending direction of the duct 4, and then bends at the mounting port 86 of the electrostatic fine particle water generator 6 to be connected to the downstream side of the narrow portion 81 a of the venturi path 81. The

  The heat dissipation path 85 is formed by a path different from the generation path 84 and is connected to the discharge port 83 of the venturi path 81.

  Then, the electrostatic fine particle water generator 61 is disposed in the generation path 84, and the electrostatic fine particle water generator 6 is attached to the mounting opening 86 so that the heat radiation fins 63 are disposed in the heat radiation path 85.

  At this time, the counter electrode 61 c of the electrostatic fine particle water generation unit 61 is disposed at the connection port 88 between the venturi path 81 and the generation path 84. Further, the mounting opening 86 is closed by the insulating plate 64 of the electrostatic fine particle water generator 6, and the generation path 84 and the heat dissipation path 85 are separated.

  As described above, according to Bernoulli's theorem, air from the generation path 84 easily flows into the narrow portion 81a where the pressure is low, and a stronger air flow than the heat dissipation path 85 is formed.

  Here, the small diameter pipe 92 of the aspirator 9 is connected to the generation path 84 and the heat dissipation path 85 as shown in FIG.

  The aspirator 9 is necessary for an air conditioner that automatically adjusts the temperature. The aspirator 9 uses Bernoulli's theorem to introduce the air in the vehicle interior into the inside air intake port 91, and a temperature detection sensor (see FIG. The temperature in the passenger compartment is detected by a not shown).

  The aspirator 9 is formed in a pipe shape by a large-diameter pipe 93 on the inside air intake port 91 side and a small-diameter pipe 92 connected to the aspirator 9. For example, the aspirator 9 is provided on the side of the steering of the instrument panel. Air in the passenger compartment is introduced from the inside air intake 91.

  For this reason, air can be taken in from the location different from the duct 4 by connecting the end part of the production | generation path 84 and the thermal radiation path 85 to this aspirator 9. FIG.

  Then, the air taken in by the aspirator 9 generates electrostatic fine particle water M in the generation path 84, and the heat dissipation fins 63 are cooled in the heat dissipation path 85.

  Next, the effect | action of 1 A of vehicle air conditioners of a present Example is demonstrated.

  The thus configured vehicle air conditioner 1 </ b> A of this embodiment takes in the air flowing through the duct 4 from the intake port 82 and forms an air flow in the venturi path 81.

  On the other hand, air is taken in from the aspirator 9 and flows through the generation path 84 where the electrostatic fine particle water generation unit 61 is disposed and the heat dissipation path 85 where the radiation fins 63 are disposed.

  Then, by connecting the generation path 84 to the downstream side of the narrow portion 81a of the venturi path 81, the electrostatic fine particle water M generated in the generation path 84 is discharged from the discharge port 83 on the air flow of the venturi path 81. can do.

  That is, since the generation path 84 is connected to the vicinity of the narrow portion 81a where the wind speed of the venturi section 81 is the fastest, the electrostatic fine particle water M flowing into the venturi path 81 from the connection port 88 of the generation path 84 is efficiently released. It can be carried to the exit 83.

  By providing the venturi path 81 in this way, it is possible to form a flow of air necessary for discharging the electrostatic fine particle water M without being greatly influenced by the wind speed and static pressure inside the duct 4. .

  Further, if the air flowing from the portion other than the opening 4a of the duct 4 to the generation path 84 and the heat radiation path 85 is secured, the air volume can be secured without being influenced by the wind speed or static pressure inside the duct 4. Can do.

  Furthermore, since the air flowing inside the duct 4 is air dehumidified by the evaporator 21, it is possible to reliably generate dew condensation water by taking in air containing more moisture than that and flowing it through the generation path 84. It is easy to maintain a state where the electrostatic fine particle water M can be continuously generated.

  Other configurations and functions and effects are substantially the same as those in the above-described embodiment, and thus description thereof is omitted.

  The best mode and examples of the present invention have been described in detail above with reference to the drawings. However, the specific configuration is not limited to this mode and examples, and does not depart from the gist of the present invention. A degree of design change is included in the present invention.

  For example, in the above-described embodiment, the case where the housing portion 5 is mounted on the side vent duct 41 has been described. However, the present invention is not limited to this, and is configured to be mounted on another duct such as the center vent duct 42. Also good.

  Moreover, although the said embodiment demonstrated the case where the aspirator 9 was connected to the production | generation path 84 and the heat radiating path 85, and air was taken in from the different place from the duct 4, it is not limited to this, Other inside air is not limited to this.
