In the following description, the length direction of the vehicle 1 corresponds to the left-right direction in FIGS. 1 and 2, and the width direction of the vehicle 1 corresponds to the up-down direction in FIG. 2.

  As shown in FIG. 1, a vehicle air conditioner 10 is installed outside the vehicle above the vehicle 1. The vehicle air conditioner 10 performs air conditioning in the vehicle 1. The vehicle air conditioner 10 is disposed at the center in the width direction of the vehicle 1.

  As shown in FIG. 2, a ceiling air inlet 2 a and a ceiling air outlet 2 b are formed in the ceiling 2 of the vehicle 1. The ceiling inlet 2a is an opening for taking in air from the vehicle 1 to the vehicle air conditioner 10. The ceiling exhaust port 2 b is an opening for exhausting air from the vehicle air conditioner 10 into the vehicle 1. The ceiling air inlet 2a is formed so as to extend in the length direction of the vehicle 1 at both ends in the width direction of the vehicle 1 and closer to the center. Moreover, the ceiling exhaust port 2b is formed in two places here in the center direction of the length direction and the width direction of the vehicle 1 at predetermined intervals in the width direction.

  As shown in FIG. 1, a decorative panel 3 is attached inside the vehicle above the vehicle 1. The decorative panel 3 is arranged at a predetermined distance from the ceiling 2 of the vehicle 1 downward. The ceiling air inlet 2a and the ceiling air outlet 2b are formed at positions that are hidden by the shadow of the decorative panel 3 and are not visible to the passengers. The decorative panel 3 is formed with an in-vehicle intake port 3a, an in-vehicle exhaust port 3b, and an in-vehicle exhaust port 3b. The in-vehicle intake port 3a communicates with the ceiling intake port 2a. Each of the in-vehicle exhaust port 3b and the in-vehicle auxiliary exhaust port 3c communicates with the ceiling exhaust port 2b.

  The in-vehicle intake port 3 a is formed in pairs at both ends in the width direction of the vehicle 1. Each in-vehicle intake port 3a is disposed closer to the end in the width direction of the vehicle 1 than the ceiling intake port 2a. In addition, the vehicle intake ports 3 a are disposed at two locations in the length direction of the vehicle 1. Therefore, here, the in-vehicle intake ports 3a are formed at a total of four locations. Further, a plurality of in-vehicle exhaust ports 3b are formed at a central portion in the width direction of the vehicle 1 with a predetermined interval in the length direction of the vehicle 1 (six locations in FIG. 2). Further, the in-vehicle auxiliary exhaust port 3 c is formed at two locations on both sides of the in-vehicle exhaust port 3 b in the vehicle width direction so as to extend in the length direction of the vehicle 1.

  As shown by the arrows in FIG. 3, the vehicle air conditioner 10 sucks air in the vehicle 1 through the in-vehicle intake port 3a and the ceiling intake port 2a. Then, the vehicle air conditioner 10 blows the sucked air into the vehicle 1 through the ceiling exhaust port 2b, the vehicle interior exhaust port 3b, and the vehicle interior auxiliary exhaust port 3c, as shown by the arrows in FIG. ing. The vehicle air conditioner 10 performs air conditioning in the vehicle 1 while circulating the air in the vehicle 1 in this manner. Here, the ceiling air inlet 2a and the vehicle interior air inlet 3a are arranged so as to be shifted in the respective vertical directions. For this reason, the air in the vehicle 1 flows upward from both ends in the width direction of the vehicle 1 toward the center.

  Although not shown, the vehicle air conditioner 10 flows through, for example, a refrigerant circuit that circulates refrigerant by connecting a compressor, a condenser, a throttling device, and an evaporator, and a condenser and an evaporator. And a blower that supplies air to be exchanged with the refrigerant.

  A control device 11 of the vehicle air conditioner 10 is disposed on the ceiling 2 side of the decorative panel 3. The control device 11 is configured by a microcomputer, for example. The control device 11 controls the entire vehicle air conditioner 10.

(Not shown).

  In addition, a dust removing device 20 for an air conditioner is installed in an air path from the in-vehicle intake port 3a to the ceiling intake port 2a. The dust remover 20 is for filtering and collecting dust from the air entering the air inlet (ceiling air inlet 2a) of the vehicle air conditioner 10 and supplying clean air to the vehicle air conditioner 10. is there. The control device 11 also performs drive control of the dust removing device 20.

  Two dust removal device mounting frames 12 are fixed to both ends of the vehicle width direction on the vehicle 1 side of the ceiling 2. In these dust removing device attachment frames 12, two openings 12 a are formed in the longitudinal direction of the vehicle 1 corresponding to the vehicle intake ports 3 a. The air which the air conditioning apparatus 10 for vehicles passes through these opening parts 12a passes. A dust remover 20 is detachably attached to each dust remover mounting frame 12 corresponding to each opening 12a.

4 is a schematic side cross-sectional view showing, in an enlarged manner, the periphery (inside the circle shown in FIG. 3) of the installation portion of the dust removing device 20 of FIG. The dust removing device 20 will be described in detail with reference to FIG.
The dust removing device 20 includes a housing 21. The housing 21 is formed with a dust remover intake port 20a and a dust remover exhaust port 20b. A filter 22 is provided in the housing 21. The filter 22 is a mesh fabric made of, for example, a Saran material in the form of a roll.

  The housing 21 of the dust removing device 20 is provided on the upstream side of the air inlet (ceiling air inlet 2a) of the vehicle air conditioner 10. Therefore, the filter 22 in the housing 21 is also provided on the upstream side of the air inlet (ceiling air inlet 2a) of the vehicle air conditioner 10. The filter 22 is for removing dust from the air entering the air inlet (ceiling air inlet 2a) of the vehicle air conditioner 10.

  The filter 22 is bridged between the drive shaft 23 and the driven shaft 24. The drive shaft 23 is driven by a motor (not shown). The driven shaft 24 is rotated following the drive shaft 23. The motor is a driving unit that rotationally drives the filter 22. That is, when the drive shaft 23 is rotated by the motor, the driven shaft 24 is also rotated along with the rotation, and the filter 22 is wound around the drive shaft 23 side.

  An idler 25 is provided between the drive shaft 23 and the driven shaft 24. An appropriate tension is applied to the filter 22 by the idler 25. In this way, the drive shaft 23 and the driven shaft 24 are prevented from idling with respect to the filter 22. The motor is electrically connected to the control device 11 (see FIG. 1) of the vehicle air conditioner 10 and is driven and controlled by the control device 11. In the first embodiment, the filter 22 is described as an example of a roll. However, the filter 22 is not particularly limited and may be a filter that does not wind up.

  The filter 22 is configured so that the in-vehicle air passes in the direction indicated by the dotted arrow in FIG. The filter 22 is an upstream surface (filtering region surface 22a) orthogonal to the passing direction of the in-vehicle air, and filters and collects coarse dust from the in-vehicle air flowing in from the dust removing device intake port 20a. The filtration region surface 22a is configured to substantially match the opening area of the dust remover intake port 20a. Further, upstream and downstream surfaces of the filter 22 that are orthogonal to the in-vehicle air passage direction (hereinafter, may be referred to as air passage surfaces) and the air inlet of the vehicle air conditioner 10 are the air passage surfaces. Each is arranged so as to be shifted in the vertical direction. In the following description, the filtration region surface 22a includes an air passage surface including a downstream surface.

  The dust remover 20 includes a discharge device 100 at the dust remover exhaust port 20b. A discharge device mounting frame 200 that supports the discharge device 100 is disposed in the dust removal device exhaust port 20b. The discharge device 100 is detachably attached to the discharge device mounting frame 200. Therefore, the discharge device mounting frame 200 is provided between the air inlet (ceiling air inlet 2 a) of the vehicle air conditioner 10 and the filter 22. The discharge device 100 is attached to the ceiling intake port 2a side of the discharge device mounting frame 200.

  Discharge device 100 is installed closer to the center in the width direction of vehicle 1 than the center of filtration region surface 22a of filter 22. The ceiling air inlet 2a is closer to the center in the width direction of the vehicle 1 than the air inlet 3a in the vehicle. Therefore, by installing the discharge device 100 closer to the center in the width direction of the vehicle 1 than the center of the filtration region surface 22a of the filter 22, the in-vehicle air can pass smoothly.

  A handle 101 is provided at one end of the discharge device 100. The discharge device 100 is attached in a direction in which the handle 101 is on the center side in the width direction of the vehicle 1. A pressing member 26 is provided at the edge (here, the end surface) of the ceiling air inlet 2a. The pressing member 26 is pressing means that contacts the discharge device 100 attached to the discharge device mounting frame 200 and presses the discharge device 100 toward the discharge device mounting frame 200. At this time, in particular, the holding member 26 contacts the handle 101 of the discharge device 100 to hold down the discharge device 100. Therefore, in other words, the handle 101 is disposed at a position where the handle 101 can come into contact with the pressing member 26 that is a pressing unit in a state where the discharge device 100 is mounted on the discharge device mounting frame 200.

Next, further description of the discharge device 100 and the discharge device mounting frame 200 will be continued with reference to FIGS. 5 and 6.
First, as shown in FIG. 5, the discharge device 100 includes a lower frame 102, a counter electrode 103, a left intermediate frame 104, a right intermediate frame 105, and a discharge electrode in order from the side facing the dust remover exhaust port 20 b, that is, from the windward side. 106, a spring 107, and an upper frame 108 are provided. A low voltage side connection portion 109 is electrically connected to the counter electrode 103. Further, the end portion of the discharge electrode 106 is electrically connected to the high voltage side power supply terminal 110 via the spring 107.

  Here, the discharge electrode 106 and the spring 107 are arranged in parallel with the wind flow. The left intermediate frame 104 and the right intermediate frame 105 are also installed in parallel with the wind flow. Furthermore, the counter electrode 103, the low-voltage side connection portion 109, and the high-voltage side power supply terminal 110 are also installed in parallel with the wind flow.

  The lower frame 102 is disposed on the furthest upstream side of the discharge device 100, and is entirely made of resin, for example. The lower frame 102 is formed with an opening for taking outside air into the discharge device 100. The openings formed in the lower frame 102 have a lattice shape so that human fingers do not enter the inside of the discharge device 100.

  The upper frame 108 is disposed on the most leeward side of the discharge device 100, and is entirely made of resin, for example. The upper frame 108 has an opening for discharging the air taken into the discharge device 100 from the opening of the upper frame 108 to the outside of the discharge device 100. A handle 101 is integrally formed on the upper frame 108. The handle 101 is used when a person holds the discharge device 100 by hand.

  The main part of the discharge electrode 106 is composed of a long plate-shaped member made of metal. As the metal constituting the discharge electrode 106, for example, tungsten, copper, nickel, stainless steel, zinc, iron, molybdenum and the like are suitable. The discharge electrode 106 is made of an alloy containing the metal as a main component, the surface of the metal is plated with a noble metal such as silver, gold, or platinum, or a carbon (graphite) layer or an oxide film is generated. Or may be configured.

  The discharge electrode 106 has a rectangular shape whose cross section is surrounded by a short side and a long side. For example, the cross section of the discharge electrode 106 may have a short side length of 0.01 to 0.1 mm and a long side length of 0.1 to 1.0 mm. A terminal having a ring shape is attached to each end of the discharge electrode 106 by pressure bonding or welding. The discharge electrode 106 is accommodated in the discharge device 100 in a state where the intermediate portion is folded about 2 to 4 times.

  The spring 107 is for applying a predetermined tension to the discharge electrode 106. The spring 107 is made of a metal member. Each end of the discharge electrode 106 is connected to a spring 107 through the terminal. The discharge electrode 106 is attached to the high-voltage power supply terminal 110 while being pulled in the longitudinal direction by the spring 107.

  The left intermediate frame 104 and the right intermediate frame 105 are for supporting the discharge electrode 106 in the discharge device 100. These intermediate frames are entirely made of resin, for example. The left intermediate frame 104 is attached to one end of the lower frame 102. The right intermediate frame 105 is attached to the other end of the lower frame 102. The left intermediate frame 104 and the right intermediate frame 105 are provided with a member for folding the discharge electrode 106 and a member for arranging the discharge electrode 106 at an appropriate position.

  The counter electrode 103 is manufactured by cutting and bending a metal plate-like member. As a metal constituting the counter electrode 103, for example, tungsten, copper, nickel, stainless steel, zinc, iron, molybdenum, or the like is preferable. The counter electrode 103 may be composed of an alloy containing the metal as a main component, or may be composed of a surface of the metal plated with a noble metal such as silver, gold, or platinum.

  The counter electrode 103 has a plate shape, and a plurality of plate-like members are arranged side by side, and are inclined so as to be inclined at a predetermined angle with respect to the opening surface of the upper frame 108 and the opening surface of the lower frame 102. Has been. In the first embodiment, the counter electrode 103 is installed so as to have an angle of 45 degrees or less with respect to the opening surface of the lower frame 102.

  In addition, the counter electrode 103 can be formed more precisely by manufacturing from a metal plate as compared to the case of manufacturing by resin molding. In addition, if the counter electrode 103 is manufactured from a metal plate, it is possible to significantly suppress the inclination from changing over time.

  The air taken into the dust remover 20 flows from the dust remover exhaust port 20b to the ceiling intake port 2a. The discharge device 100 is attached to the dust removal device exhaust port 20b, and the air taken into the discharge device 100 from the opening of the lower frame 102 of the discharge device 100 passes obliquely toward the ceiling intake port 2a. For this reason, the plate-like counter electrode 103 hinders ventilation. Therefore, by disposing the counter electrode 103 so as to be inclined at a predetermined angle, it is possible to suppress the hindrance to the flow of the wind, and to suppress the decrease in the air volume, the generation of noise, and the increase in power consumption due to the hindrance of the wind.

  At this time, since air taken in from the dust removing device intake port 20a is taken in perpendicular to the filtration region surface 22a, the counter electrode 103 is also inclined with respect to the filtration region surface 22a. When passing the wind through the filtration area surface 22a, it is better to take the air perpendicular to the filtration area surface 22a. For this reason, it is possible to suppress the wind hindrance most by allowing the wind to pass vertically on the filtration region surface 22a and allowing the wind to pass obliquely in the discharge device 100. At this time, the angle of the counter electrode 103 is desirable to be parallel to the passing wind.

  As described above, the low voltage side connection portion 109 is electrically connected to the counter electrode 103. The discharge electrode 106 is electrically connected to a high voltage side power supply terminal 110 via a spring 107. Both the low-voltage side connection portion 109 and the high-voltage side power supply terminal 110 are made of a metal member. And the high voltage | pressure side electric power feeding terminal 110 is connected to the high voltage board | substrate 204 mentioned later for supplying the voltage of 4-7 kV to the discharge electrode 106 (and between the counter electrodes 103). The low-voltage side connection unit 109 is connected to the power supply GND.

  In the discharge device 100 configured as described above, the discharge electrode 106 and the counter electrode 103 are accommodated in a frame (lower frame 102 and upper frame 108) having openings on the windward side and the leeward side. Further, the discharge device 100 includes a low voltage side connection portion 109 and a high voltage side power supply terminal 110 which are discharge device side terminals electrically connected to the discharge electrode 106 and the counter electrode 103. These discharge device side terminals (low voltage side connection portion 109 and high voltage side power supply terminal 110) are provided exposed on the outer surface of the frame (lower frame 102 and upper frame 108).

  Furthermore, the discharge device 100 includes a handle 101 provided at one end of the frame. And the discharge device side terminal (the low voltage | pressure side connection part 109 and the high voltage | pressure side electric power feeding terminal 110) is arrange | positioned at the other end part of the flame | frame. Therefore, the portion pressed by the pressing member 26 can be used also as the handle 101, and when the handle 101 is pressed, the discharge device side terminals (the low voltage side connection portion 109 and the high voltage side power supply terminal 110) are connected to the discharge device mounting frame 200 side. It becomes possible to press it firmly to.

  Next, as shown in FIG. 6, the discharge device mounting frame 200 includes a support portion 201, a power supply case 202, a lower power supply case 203, a high voltage substrate 204, a support side low voltage terminal 205, a support side high voltage terminal 206, a hook portion 207, Ribs 208 and lattice portions 209 are provided.

  The support unit 201 is for supporting the discharge device 100. The support part 201 is configured as a frame formed entirely of resin, for example. The support part 201 is formed with an opening other than the frame for maintaining the strength in places other than the power supply case 202 including the place where the discharge device 100 is attached. For this reason, it does not obstruct the passage of the taken-in wind. That is, the support part 201 is formed as a framework that can maintain a predetermined strength at a place other than the power supply case 202.

  The power supply case 202 is formed integrally with the support unit 201. A lower power supply case 203 is disposed on the back side of the power supply case 202. For example, the lower power supply case 203 may be formed of the same resin as that of the support unit 201.

  A high voltage board 204 is installed in the power supply case 202 and the lower power supply case 203. A support-side low-voltage terminal 205 and a support-side high-voltage terminal 206 are electrically connected to the high-voltage board 204. Both the support-side low-voltage terminal 205 and the support-side high-voltage terminal 206 are made of a metal member.

  The support-side low-voltage terminal 205 is connected to the low-voltage side connection unit 109 when the discharge device 100 is attached to the support unit 201. The support-side high-voltage terminal 206 is connected to the high-voltage-side power supply terminal 110 when the discharge device 100 is attached to the support unit 201. That is, the discharge device mounting frame 200 is provided on the mounting frame side provided at a position facing the discharge device side terminals (the low voltage side connection portion 109 and the high voltage side power supply terminal 110) of the discharge device 100 attached to the discharge device mounting frame 200. A support side low voltage terminal 205 and a support side high voltage terminal 206 which are terminals are provided.

  In this way, the discharge device 100 is attached to the support unit 201, and the low voltage side connection unit 109 and the support side low voltage terminal 205, and the high voltage side power supply terminal 110 and the support side high voltage terminal 206 are connected to each other. And a voltage of 4 to 7 kV is supplied between the counter electrodes 103).

  The hook portion 207 is for attaching the discharge device mounting frame 200 to the dust removing device 20. The shape of the hook portion 207 is not particularly limited, and may be any shape that allows the discharge device mounting frame 200 to be hooked and attached to the dust removing device 20. For example, the hooking portion 207 may be formed in a shape in which a part of the support portion 201 protrudes toward the back side of the drawing and the tip is hooked.

  The rib 208 supports a surface on the opposite side of the handle 101 of the upper frame 108 of the discharge device 100. The shape of the rib 208 is not particularly limited, and may be a shape that can support the upper frame 108 of the discharge device 100. For example, the rib 208 may have a shape such that a part of the support part 201 protrudes to the front side of the drawing and is inserted into a part of the upper frame 108 of the discharge device 100.

  The grid portion 209 is a portion to which the handle 101 is attached when the discharge device 100 is attached to the support portion 201. The lattice portion 209 has a lattice shape, so that the handle 101 can be easily grasped by hand when the discharge device 100 is removed. However, the specific configuration of the lattice unit 209 is not particularly limited.

  The discharge device mounting frame 200 is configured as described above, and the surface opposite to the handle 101 of the upper frame 108 is fitted into the rib 208 of the support portion 201 of the discharge device mounting frame 200 and is pushed in as it is. 100 fits in the support unit 201. By doing so, it is possible to electrically connect the low-voltage side connecting portion 109 and the support-side low-voltage terminal 205, and the high-voltage side power supply terminal 110 and the support-side high-voltage terminal 206 at the same time as supporting the discharge device 100. Yes.

  Next, operations of the vehicle air conditioner 10 and the dust remover 20 will be described. When the vehicle air conditioner 10 is driven by the control device 11, the air in the vehicle 1 passes through the vehicle intake port 3a, the dust removal device 20 and the ceiling intake port 2a and is taken into the vehicle air conditioner 10. . At this time, dust contained in the in-vehicle air is removed by the dust removing device 20, and clean air flows into the vehicle air conditioner 10. The air flowing into the vehicle air conditioner 10 is conditioned air in the vehicle air conditioner 10. The conditioned air is discharged from the vehicle air conditioner 10 and then blown into the vehicle 1 through the ceiling exhaust port 2b, the vehicle interior exhaust port 3b, and the vehicle interior auxiliary exhaust port 3c.

  In the dust remover 20, the in-vehicle air that has flowed into the housing 21 from the dust remover intake port 20 a first passes through the filtration region surface 22 a of the filter 22. The coarse dust of the air in the vehicle is filtered by the filtration area surface 22a. Thereafter, when the vehicle interior air passes through the discharge device 100, airborne bacteria, molds, viruses, allergens, and the like in the vehicle interior air are removed and inactivated to become clean air. Then, after the vehicle interior air becomes clean air, the vehicle interior air is discharged toward the vehicle air conditioner 10 from the dust remover exhaust port 20b.

  In the discharge device 100, when the vehicle air conditioner 10 is driven by the control device 11, a voltage of 4 to 7 kV is applied to the discharge electrode 106, and an electric field is formed between the discharge electrode 106 and the counter electrode 103. Corona discharge occurs. Bacteria, mold, viruses and allergens contained in the air passing through the discharge device 100 are destroyed when passing between the discharge electrode 106 and the counter electrode 103 due to the application of an electric field and discharge, and are killed or not. Activate. The killed and inactivated airborne bacteria, mold, virus and allergen are discharged out of the discharge device 100 together with air. As a result, it is possible to remove and inactivate living floating bacteria, molds, viruses, and allergens that existed in a room such as a vehicle.

Next, the removal and attachment of the discharge device 100 when necessary (for example, during maintenance) will be described with reference to FIGS.
First, as shown in FIG. 7, the dust removing device intake port 20 a can be opened and closed by turning one side portion in the width direction of the vehicle 1 as an axis. And in the state which opened the dust removal apparatus inlet port 20a, the housing | casing 21 of the dust removal apparatus 20 can also be opened and closed by turning the one side part of the outer side of the width direction of the vehicle 1 as an axis | shaft.

  Here, the discharge device mounting frame 200 is fixed to the dust removing device exhaust port 20 b of the housing 21. Therefore, the housing 21 to which the filter 22 is attached and the discharge device attachment frame 200 to which the discharge device 100 is attached move together when the housing 21 is opened and closed. That is, the housing 21 and the discharge device mounting frame 200 are integrally provided so as to be movable with respect to the ceiling air inlet 2a. Note that when the casing 21 and the discharge device mounting frame 200 are opened and closed, the discharge device 100 is held by the discharge device mounting frame 200 and moves together with the discharge device mounting frame 200.

  For this reason, by opening the casing 21, the discharge device 100 and the discharge device mounting frame 200 move to the positions shown in FIG. In this state, the discharge device 100 is opened so as to be exposed toward the inner side in the width direction of the vehicle 1, and the operator can easily remove and attach the discharge device 100. Furthermore, since the handle 101 of the discharge device 100 is located on the inner side in the width direction of the vehicle 1, the handle 101 comes to a position that is easy for an operator to grasp. Since the dust removing device 20 is arranged at the upper part of the vehicle 1, the operation is performed by raising the hand. In this way, the discharge device 100 is positioned in front of the operator only by opening the housing 21 of the dust removing device 20. And maintainability is good.

  Here, the discharge device 100 is supported by the support unit 201 in a state where the surface of the upper frame 108 opposite to the handle 101 is fitted to the rib 208 of the support unit 201. Therefore, the discharge device 100 can be easily detached from the discharge device mounting frame 200 by grasping the handle 101 and turning the discharge device 100 relative to the discharge device mounting frame 200 with the rib 208 as a fulcrum as shown in FIG. Can do.

  When the discharge device 100 is attached, the reverse procedure of removal may be performed. That is, first, the surface opposite to the handle 101 of the lower frame 102 of the discharge device 100 is fitted into the rib 208 of the support portion 201 of the discharge device mounting frame 200. Next, the discharge device 100 is fitted into the support portion 201 by pushing the handle 101 into the lattice portion 209 with the rib 208 as a fulcrum. When the discharge device 100 is attached to the discharge device mounting frame 200, the housing 21 and the dust removal device intake port 20a are turned and closed from the state shown in FIG.

  Here, in the state of FIG. 7 in which the housing 21 is opened, the handle 101 of the discharge device 100 and the pressing member 26 on the ceiling intake port 2a side are not in contact with each other. On the other hand, in the state of FIG. 4 in which the housing 21 is closed, the pressing member 26 is in contact with the handle 101 of the discharge device 100. In the state of FIG. 4, the pressing member 26 contacts the handle 101 (that is, a part of the upper frame 108) of the discharge device 100 and presses the discharge device 100 against the discharge device mounting frame 200. For this reason, the discharge member side terminals (low voltage side connecting portion 109 and high voltage side power supply terminal 110) and the mounting frame side terminals (support side low voltage terminal 205 and support side high voltage terminal 206) are reliably brought into contact with the holding member 26. Is possible.

  FIG. 9 is an enlarged view of the contact portion between the pressing member 26 and the handle 101 at this time. As described above, the pressing member 26 that is a pressing means is provided at the edge of the ceiling air inlet 2a. Here, the pressing member 26 includes a plurality of rod-shaped protrusions 26 a that protrude from the inner end face in the width direction of the vehicle 1 toward the outer side in the width direction of the vehicle 1 at the ceiling inlet 2 a.

  A plurality of groove portions 101a are formed in the handle 101 of the discharge device 100 corresponding to the plurality of rod-shaped protrusions 26a. The positions of the rod-shaped protrusions 26a and the groove portions 101a are adjusted so that each rod-shaped protrusion 26a fits into the corresponding groove portion 101a when the discharge device 100 is appropriately attached to the discharge device mounting frame 200.

  Here, even if the holding member 26 is not in contact with the handle 101, as long as the discharge device 100 is appropriately attached to the discharge device attachment frame 200, the discharge device side terminal (low voltage side connection portion) 109 and the high-voltage side power supply terminal 110) and the attachment frame side terminals (the support-side low-voltage terminal 205 and the support-side high-voltage terminal 206) are in contact with each other so that they can be energized. However, in a state where the pressing member 26 is not in contact with the handle 101, the discharge device 100 may not be properly attached to the discharge device attachment frame 200, and the discharge device side terminal and the attachment frame side terminal may cause poor contact. There is.

  On the other hand, in the state of FIG. 4 in which the pressing member 26 is in contact with the handle 101, the discharge device 100 is reliably attached to the discharge device mounting frame 200 at an appropriate position by the action of the pressing member 26. It is possible to reliably connect the discharge device side terminal and the attachment frame side terminal so as to allow energization.

  That is, when the discharge device 100 is not properly attached to the discharge device mounting frame 200 and the housing 21 of the dust removing device 20 is to be closed, the positions of the rod-shaped protrusions 26 a of the pressing member 26 and the groove portions 101 a of the handle 101 are changed. As a result, the rod-like protrusion 26a comes into contact with and interferes with a location where the groove 101a of the handle 101 is not provided, and the casing 21 cannot be completely closed. Therefore, the operator can notice that the discharge device 100 is not properly attached to the discharge device mounting frame 200.

  Alternatively, if the casing 21 is closed when the discharge device 100 is not properly attached to the discharge device mounting frame 200 by providing an inclination around the groove portion 101a, the rod-like protrusion 26a is caused by the inclination around the groove portion 101a. It can also be expected that the discharge device 100 is guided to fit into the groove portion 101 a and fits in an appropriate position of the discharge device mounting frame 200. The shape of the protrusion of the pressing member 26 may be a shape other than a rod shape as long as the handle 101 of the discharge device 100 can be pressed.

  Further, the discharge device 100 includes a discharge device side terminal (low voltage side connection portion 109 and high voltage side power supply terminal 110) and a mounting frame side terminal (support side low voltage terminal 205 and support side high voltage terminal 206) in the discharge device mounting frame 200. You may make it provide the detection means which detects that it exists in the position which touches.

  FIG. 10 shows an example of such detection means. In the example shown in FIG. 10, a switch 27 provided on the discharge device mounting frame 200 is provided as a detection means. Here, the switch 27 is provided in the lattice part 209 in particular. The switch 27 is pressed by the discharge device 100 when the discharge device 100 is attached to an appropriate position of the discharge device mounting frame 200. On the other hand, when the discharge device 100 is not attached to an appropriate position of the discharge device attachment frame 200, the switch 27 is not pressed.

  Therefore, for example, by providing an LED or the like that is turned on according to the operating state of the switch 27 (whether or not it is pressed), the operator can attach the discharge device 100 to an appropriate position of the discharge device mounting frame 200. It is possible to easily know whether or not the discharge device side terminal and the attachment frame side terminal are connected so as to be energized.

  For example, after the discharge device 100 is maintained, when the discharge device 100 is attached to the discharge device mounting frame 200 and the housing 21 of the dust removing device 20 is attached to the vehicle 1, the handle 101 of the discharge device 100 is pressed by the pressing member 26. By pushing in as it is, the discharge device 100 is securely fitted in the support portion 201. At that time, the switch 27 is also pushed by the discharge device 100 to detect that the discharge device 100 is engaged.

  If the push-in is insufficient, it is determined that the switch 27 is not pushed in and the discharge device 100 is not securely fitted. By providing the switch 27 as such a detecting means, it is possible to detect whether or not the discharge device 100 is securely attached to an appropriate position. Therefore, the discharge device side terminal (low voltage side connection portion 109 and high voltage side power supply terminal 110) and the attachment frame side terminal (support side low voltage terminal 205 and support side high voltage terminal 206) are more reliably connected so as to be energized. As a result, it is possible to suppress abnormal discharge due to poor contact and to ensure good air cleaning performance.

  The dust remover of the air conditioner configured as described above is provided on the upstream side of the ceiling intake port 2a of the air conditioner, and removes dust from the air entering the ceiling intake port 2a, and the ceiling intake port 2a. And the discharge device mounting frame 200 provided between the filter 22 and the ceiling inlet 2a side, and the discharge electrode 106 and the inside of the frame (upper frame 108 and lower frame 102) having openings on the windward side and leeward side. And a discharge device 100 in which the counter electrode 103 is accommodated.

  In addition, the discharge device 100 includes a discharge device side terminal (a low voltage side connection portion 109 and a high voltage side power supply terminal 110) provided to be exposed on the outer surface of the frame and electrically connected to the discharge electrode 106 and the counter electrode 103. The discharge device mounting frame 200 is provided with mounting frame side terminals (a support side low voltage terminal 205 and a support side high voltage) provided at positions facing the discharge device side terminals of the discharge device 100 mounted on the discharge device mounting frame 200. Terminal 206).

  Then, a pressing member that is a pressing unit that contacts the discharge device side terminal and the mounting frame side terminal by contacting the frame of the discharge device 100 attached to the discharge device mounting frame 200 at the edge of the ceiling air inlet 2a. A member 26 is provided.

  Therefore, when the discharge device 100 is attached to the dust removal device 20, the discharge device 100 is securely attached to an appropriate position where the terminal on the discharge device 100 side and the terminal on the dust removal device 20 side can be brought into contact with each other so as to be energized. be able to. That is, the discharge device 100 can be reliably attached to an appropriate position of the discharge device mounting frame 200, and the discharge device side terminals (low voltage side connection portion 109 and high voltage side power supply terminal 110) and the mounting frame side terminals (support side low voltage terminals). 205 and the support-side high-voltage terminal 206) can be surely connected so as to be energized.

  Accordingly, abnormal discharge due to poor contact can be suppressed, airborne bacteria, mold, viruses and allergens can be efficiently removed and inactivated, and good air cleaning performance can be ensured.

  The vehicle air conditioner 10 described in the first embodiment is, for example, an air circulator such as a blower that simply circulates air in addition to a device that performs temperature adjustment such as heating or cooling or a device that performs dehumidification. Including aircraft.

  Moreover, the dust remover for an air conditioner according to the present invention and the air conditioner equipped with the dust remover can be mounted, for example, inside various railway vehicles. Although the vehicle air conditioner 10 has been described as an example of the air conditioner, the present invention is not limited to this and may be an air conditioner used in a building or the like.
