Description

Air conditioner

The present invention relates to an air conditioner that performs air conditioning by releasing air containing ions.

Conventionally, an air conditioner that purifies air by releasing ions into the air has been used. Such an air conditioner includes an ion generator that generates positive ions H ⁺ (H ₂ O) _m and negative ions O ₂ ⁻ (H ₂ O) _n , and generates the generated ions in the air. To release. Here, m and n are arbitrary natural numbers. Ions released into the air attach around and surround fungi, bacteria, viruses, etc. in the air, and the action of hydroxyl radicals of the active species produced during the attachment causes fungi, bacteria, viruses, etc. Inactivate. Such techniques are disclosed in, for example, Patent Documents 1 to 3.

Also, Patent Document 4 discloses a technique for installing an air conditioner under the floor of a building. When the air conditioner is installed under the floor, an air outlet is provided on the floor of the building.

The air conditioner installed under the floor has an outlet on the top surface. At the outflow port, a net-like lid is arranged to prevent foreign matter from falling from the outflow port while allowing air to be released. However, in spite of the presence of this lid, there is a risk that foreign matter will fall from the outlet and enter the air conditioner. For example, liquid spilled on the floor of a building may enter the device's inner surface from the edge of the outlet. If a foreign object enters the interior, the ion generator cannot generate a sufficient amount of ions due to the foreign object, or the foreign object may become clogged in the air path and interfere with the air flow. May occur. Thus, in the air conditioner installed under the floor, due to the occurrence of a problem, a sufficient amount of ions cannot be diffused in the air, and the ability to clean the air may deteriorate. There is.

The present invention has been made in view of such circumstances, and an object of the present invention is to suppress the deterioration of the ability of air cleaning using ions by preventing the occurrence of problems due to the fall of foreign matter. An object of the present invention is to provide an air conditioner that can perform the above-described operation.

An air conditioner according to the present invention is provided with an air inlet and outlet, and includes an ion generator in the middle of a path through which air passes from the inlet to the outlet, and the ion generator is generated. In the air conditioner that discharges air containing ions from the outlet, the outlet opens above the ion generator, and the ion generator generates ions generated in the air flowing through the path. It is characterized in that it has an ion emission port for discharging the ion, and the ion emission port is arranged downward.

In the present invention, in an air conditioner that includes an ion generator and discharges air containing ions from an outlet port above the ion generator, the ion generator is disposed with the ion emission port facing downward. Even when foreign matter falls from the outflow port, foreign matter is prevented from entering the ion emission port.

The air conditioner according to the present invention further includes a plate-like protective member that covers the top of the ion generator below the outflow port.

In the present invention, by providing a protective member that covers the top of the ion generator below the outflow port, even if the foreign material falls from the outflow port, the foreign material directly falls into the ion generator. It is prevented.

The air conditioner according to the present invention is characterized in that the protective member is in close contact with the ion generator.

In the present invention, the protective member is in close contact with the ion generator, so that air that should flow out from the outlet does not enter between the protective member and the ion generator.

The air conditioner according to the present invention further includes a member that connects a surface of the ion generator and an end of the protective member.

In the present invention, by providing a member that connects the surface of the ion generator and the end of the protection member in the air conditioner, the air flowing along the surface of the ion generator smoothly reaches the end of the protection member. Flowing.

The air conditioner according to the present invention is characterized in that the ion generator is disposed in a casing in which the outflow port is formed on an upper surface, and is not in direct contact with the inner surface of the casing. And

In the present invention, since the ion generator is not in direct contact with the inner surface of the housing, even if the foreign material enters the air conditioner through the inner surface of the housing, the foreign material remains in the ion generator. Hard to touch.

The air conditioner according to the present invention is characterized in that at least a part of a path of air from which ions are discharged from the ion discharge port is narrowed from upstream to downstream.

In the present invention, the path through which the air containing the ions discharged from the ion discharge port flows is continuously narrowed from the upstream to the downstream of the air, and the flowing air gradually accelerates. The high-speed air flow suppresses the fall of foreign matters and the clogging of foreign matters.

The air conditioner according to the present invention further includes a member for guiding the flow of air flowing in from the inlet to the ion emission port.

In the present invention, the air conditioner includes a member that guides the air flowing in from the inlet to the ion discharge port, so that ions are efficiently included in the air that flows in.

In the present invention, the air conditioner has a problem that the ion generator cannot generate a sufficient amount of ions due to the foreign matter, or the foreign matter is blocked in the air path and obstructs the air flow. It becomes difficult to occur. For this reason, in an air conditioning apparatus, this invention has the outstanding effect that the deterioration of the capability of the air cleaning using ion is suppressed.

Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof.
FIG. 1 is a schematic view showing a state in which the air conditioner of the present invention is installed in a building. The air conditioning apparatus 1 according to the present invention forms part of an air conditioning system and is installed under the floor of a building 5. In FIG. 1, the typical cross section which looked at the building 5 from the side is shown. The air conditioner 1 is installed below the floor 51 of the building 5 so that the upper surface is substantially the same as the upper surface of the floor 51. A control device 2 for controlling the operation of the air conditioner 1 is installed in the building 5. A blower 3 is installed in the building 5, and the blower 3 and the air conditioner 1 are connected by a duct 4. The blower 3 sends air to the duct 4, and the sent air flows through the duct 4 and flows into the air conditioner 1, and the air conditioner 1 releases the air that has flowed into the space above the floor 51. In FIG. 1, the air flow is indicated by arrows.

FIG. 2 is a schematic diagram showing the appearance of the air conditioner 1. The air conditioner 1 has a configuration in which a lid 12 having a net-like structure covers an upper side of a rectangular parallelepiped casing 11. FIG. 3 is a schematic perspective view showing the configuration inside the housing 11 of the air conditioner 1. In FIG. 3, the outer shape of the housing 11 is indicated by a two-dot chain line. An air inlet 111 is formed on the bottom surface of the housing 11. The duct 4 is connected to the bottom surface of the housing 11, and the air flowing through the duct 4 flows into the housing 11 from the inlet 111. An air outlet 112 is formed on the upper surface of the housing 11. The air that has flowed into the housing 11 from the inflow port 111 flows out from the outflow port 112. The lid portion 12 is a lid that covers the outflow port 112. In the state where the air conditioner 1 is installed, the upper surface of the lid 12 is substantially flush with the upper surface of the floor 51. Since the lid portion 12 has a net-like structure, the air flowing out from the outflow port 112 is allowed to pass through while the foreign matter is prevented from falling into the housing 11.

The air conditioner 1 includes two

ion generators

13 and 13 in a housing 11. FIG. 4 is a schematic perspective view of the ion generator 13. The ion generator 13 is formed in a rectangular parallelepiped shape, and generates positive ions H ⁺ (H ₂ O) _m and negative ions O ₂ ⁻ (H ₂ O) _n . The ion generator 13 is provided with an ion emission surface 131, and the ion emission surface 131 is provided with an open negative ion emission port 132 and a positive ion emission port 133. FIG. 4 shows a form in which two negative ion discharge ports 132 and two positive ion discharge ports 133 are provided. The distance between the negative ion emission port 132 and the positive ion emission port 133 is longer than the distance between the negative ion emission ports 132 and the distance between the positive ion emission ports 133. The ion generator 13 includes an electrode for discharge inside, and generates negative ions and positive ions by discharge. Negative ions are released from the negative ion discharge port 132 into the air, and positive ions are released from the positive ion discharge port 133 into the air. In addition, the ion generator 13 may have a form in which one negative ion outlet 132 and one positive ion outlet 133 are provided, or may be in a form in which three or more are provided.

Each ion generator 13 is arranged in parallel to the longitudinal direction of the housing 11. The two

ion generators

13 and 13 are arranged in the housing 11 without contacting the inner surface of the housing 11 with the back surface of the ion emission surface 131 facing each other. Further, each ion generator 13 is arranged with the ion emission surface 131 inclined downward. For this reason, the negative ion discharge port 132 and the positive ion discharge port 133 are directed downward. The horizontal distance between the ion emission surfaces 131 of the two

ion generators

13 and 13 is narrower toward the lower side and wider toward the upper side. Since the ion emission surface 131 faces downward, even if the foreign material falls into the air conditioner 1, the foreign material does not fall directly on the ion emission surface 131. For this reason, the possibility that foreign matter enters the ion generator 13 from the negative ion emission port 132 and the positive ion emission port 133 is low. Further, since the ion generator 13 is not in contact with the inner surface of the housing 11, the foreign material contacts the ion generator 13 even if the foreign material enters the air conditioner 1 through the inner surface of the housing 11. It is hard to do. Therefore, it is unlikely that a foreign substance enters the ion generator 13 and interferes with the generation of ions.

The position where the

ion generators

13 and 13 are arranged is in the middle of the path through which the air flowing in from the inlet 111 passes to the outlet 112. The

ion generators

13 and 13 emit ions to the passing air. Since the ion emission surfaces 131 are inclined downward, the distance between each ion emission surface 131 and the inner surface of the housing 11 is continuously narrowed from the bottom to the top.

A plate-like protective member 14 is disposed above the

ion generators

13 and 13. The position of the protection member 14 is below the outflow port 112. The protection member 14 is disposed substantially horizontally and covers the

ion generators

13 and 13 so that the

ion generators

13 and 13 are not exposed in plan view. The protection member 14 is fixed by being placed on the

ion generators

13 and 13. Further, both side ends of the upper surface of the protection member 14 are formed in a curved shape so that the upper surface and side surfaces of the protection member 14 are smoothly continuous. There is a gap through which air flows between the end of the protection member 14 and the inner wall of the housing 11. Further, there is a certain distance between the upper surface of the protection member 14 and the outlet 112. Since the protection member 14 covers the

ion generators

13 and 13, even if the foreign matter falls from the outflow port 112, the foreign matter does not fall directly on the

ion generators

13 and 13.

Projections

17 and 17 projecting from the inner surface of the housing 11 are provided at positions facing the ion emission surfaces 131 of the

ion generators

13 and 13. The protruding portion 17 is a member formed in a shape in which the protruding amount from the inner surface of the housing 11 becomes larger from the bottom to the top, and is fixed to the inner surface of the housing 11 facing the ion emission surface 131. ing. Since the ion emission surface 131 is inclined downward and the protrusion amount of the protrusion 17 increases toward the upper side, the path of the air flowing along the ion emission surface 131 is gradually narrowed from the bottom to the top. . In addition, there is a certain distance between the upper ends of the

protrusions

17 and 17 and the outlet 112.

The protective member 14 is in close contact with the upper ends of the

ion generators

13, 13, and a filling member 15 that fills the space between the respective ion generators 13 and the protective member 14 is disposed. The filling member 15 is filled in a gap between the ion generator 13 and the protection member 14, and the surface of the filling member 15 continuously connects the ion emission surface 131 of the ion generator 13 and the side end of the protection member 14. Are connected. Since the protection member 14 is in close contact with the upper end of the ion generator 13, the air flowing from the bottom to the top along the ion emission surface 131 does not enter between the protection member 14 and the ion generator 13. Further, due to the presence of the filling member 15, air is guided to the side end of the protection member 14 along the surface of the filling member 15 without colliding with the lower side of the protection member 14.

An air guide member 16 is disposed below the

ion generators

13 and 13. The air guide member 16 is formed in a triangular prism shape, and the axis of the triangular prism is arranged in parallel to the longitudinal direction of the

ion generators

13 and 13. Moreover, the air guide member 16 is disposed so as to protrude downward with one side surface of the triangular prism facing upward. The lower ends of the

ion generators

13 and 13 are covered with the air guide member 16, and the air flowing in from the inlet 111 cannot flow between the

ion generators

13 and 13. The air guide member 16 is disposed immediately above the inflow port 111, and the air flowing in from the inflow port 111 collides with the air guide member 16.

FIG. 5 is a schematic view of the configuration inside the housing 11 as viewed from above. In the outflow port 112, the protection member 14 and the

protrusions

17 and 17 are visible, and the inflow port 111 is visible in the back. The

ion generators

13 and 13 are concealed by the protective member 14 and are arranged on the upper side of the inflow port 111. Further, the

ion generators

13 and 13 are connected to the inner wall of the housing 11 by connecting

portions

134 and 134 and are fixed in a space in the housing 11. The connecting portions 134 are not shown in FIG. The

ion generators

13 and 13 are electrically connected via the connecting

portions

134 and 134. The filling

members

15 and 15 and the air guide member 16 are also hidden behind the protective member 14 in FIG. The air guide member 16 is connected to the

ion generators

13 and 13 and hung, or extends in the longitudinal direction from the

ion generators

13 and 13 and is connected to the inner wall of the housing 11.

FIG. 6 is a block diagram showing an internal functional configuration of the control device 2. The control device 2 includes a control unit 21 including a calculation unit that performs a calculation for controlling the air conditioner 1 and a storage unit that stores data necessary for the calculation. Connected to the control unit 21 is an operation unit 22 including operation buttons for receiving an operation from a user. The control unit 21 is connected to a display unit 23 that displays information necessary for operation. The display unit 23 is composed of, for example, a liquid crystal panel. The operation unit 22 and the display unit 23 may be configured with a touch panel. An external power source 20 such as a commercial power source is connected to the control unit 21, and power is supplied from the power source 20 to the control unit 21. The control unit 21 is connected to the

ion generators

13 and 13 of the air conditioner 1. Connection between the

ion generators

13 and 13 and the control unit 21 is performed through

connection units

134 and 134.

When the user operates the operation unit 22 and receives an operation start instruction from the operation unit 22, the control unit 21 performs control to operate the

ion generators

13 and 13, and indicates information indicating the operating state. Is displayed on the display unit 23. When the stop instruction is received by the operation unit 22, the control unit 21 performs control to stop the

ion generators

13 and 13. Note that the control device 2 may include a power supply inside. Moreover, the control part 21 may be provided in the air conditioning apparatus 1. In this embodiment, the operation unit 22 and the display unit 23 in the control device 2 are connected to the control unit 21 in the air conditioner 1.

Next, the operation of the air conditioner 1 will be described. FIG. 7 is a schematic view showing the inside of the air conditioner 1 in operation. In FIG. 7, the figure which looked at the inside of the air conditioning apparatus 1 from the front is shown, and the housing | casing 11 is shown with the cross section. The air sent out from the blower 3 passes through the duct 4 and flows into the air conditioner 1 from the inlet 111. Inflowed air flows from the inlet 111 to the outlet 112.

The air flowing in from the inlet 111 first collides with the air guide member 16. Since the air guide member 16 is convex downward, the path through which air flows branches on both sides of the air guide member 16. There is an ion generator 13 in the middle of each branched path. The air that flows along one of the two side surfaces other than the upper side surface of the air guide member 16 then flows along the ion emission surface 131 of the one ion generator 13. The air flowing along the other side surface of the air guide member 16 then flows along the ion emission surface 131 of the other ion generator 13. The

ion generators

13 and 13 emit ions to the air flowing along the ion emission surface 131. As a result, air containing ions flows toward the outlet 112. In FIG. 7, the air flow is indicated by arrows, negative ions are indicated by-and positive ions are indicated by +. By the air guide member 16, the air flowing in from the inflow port 111 is reliably guided to the

ion generators

13 and 13, and ions are included in the air.

The air containing ions flows upward along the ion emission surface 131, flows along the surface of the filling member 15, and reaches the side end of the protection member 14. Since the protection member 14 is in close contact with the upper end of the ion generator 13, air does not enter between the protection member 14 and the ion generator 13. Further, since air flows along the filling

members

15 and 15, the air does not hit the lower surface of the protective member 14, and air does not stay on the lower surface of the protective member 14. For this reason, the air containing ions and flowing upward along the ion emission surface 131 flows smoothly to the side end of the protection member 14. The path of the air to reach the side end of the protective member 14 is a space sandwiched between the

ion generators

13 and 13 and the

protrusions

17 and 17 and continuously narrows from the upstream side to the downstream side of the air. It becomes the composition which becomes. For this reason, the air containing ions is gradually accelerated as it flows from the bottom to the top.

The air that flows while accelerating between the

ion generators

13 and 13 and the

protrusions

17 and 17 flows out from the outlet 112. At this time, most of the air blows up from both sides of the protective member 14 and flows out from the edge portion 113 including the edge of the outlet 112 in the outlet 112. Further, part of the air flows along the upper surface of the protective member 14 from the side of the protective member 14 due to the Coanda effect, and flows out of the central portion 114 including the center of the outlet 112 in the outlet 112. Since both side ends of the upper surface of the protection member 14 are formed in a curved surface shape, the Coanda effect is likely to occur, and the air that has flowed easily wraps around the protection member 14. The air that flows out from the edge portion 113 has a higher flow velocity than the air that once flows along the upper surface of the protection member 14 and then flows out from the central portion 114. In FIG. 7, the flow velocity of the air flowing out from the outlet 112 is indicated by the length of the arrow.

The side edge of the upper surface of the protective member 14 may be formed at a right angle, but it is desirable that it is formed in a curved surface as shown in FIG. 7 so that the Coanda effect is easily generated. Moreover, the side edge of the upper surface of the protection member 14 may be formed in a streamline shape so that air can flow more easily. Moreover, the side edge of the upper surface of the protection member 14 may be formed in an obtuse angle, may be formed in a combination of a plurality of obtuse angles, and may be formed in a combination of an obtuse angle and a curved surface.

Since air flows out from the edge portion 113 of the outlet 112 at a high speed, it is possible to prevent foreign matters from falling from the periphery of the outlet 112 into the air conditioner 1. Ions contained in the air flowing out from the central portion 114 of the outlet 112 are blocked from the surroundings by the high-speed air flowing out from the edge portion 113. For this reason, ions contained in the air flowing out from the central portion 114 are efficiently diffused into the space in the building 5. The diffused ions clean the air in the building 5.

As described above, in the air conditioner 1 according to the present embodiment, foreign matter falls from the periphery of the outlet 112 into the air conditioner 1 due to the air flowing out from the edge portion 113 of the outlet 112 at a high speed. It is suppressed. Even if the foreign matter falls into the air conditioner 1, the air rises while accelerating. Therefore, it is difficult for the foreign matter to be clogged in the air path and the air flow to deteriorate. Moreover, in the air conditioning apparatus 1 according to the present embodiment, since the protection member 14 is provided on the upper side of the

ion emitters

13 and 13, foreign matter does not fall directly on the

ion emitters

13 and 13. Further, since the ion emission surface 131 is inclined downward, it is unlikely that foreign matter enters the ion generator 13 from the negative ion emission port 132 and the positive ion emission port 133. For this reason, even if a foreign substance falls from the outflow port 112 and enters the air conditioner 1, there is a low possibility that a defect occurs in the ion generator 131 due to the foreign substance. In addition, since the ion generator 13 according to the present embodiment is not in direct contact with the inner surface of the housing 11, even if foreign matter enters the air conditioner 1 through the inner surface of the housing 11, It is difficult for foreign matter to contact the ion generator 13. Therefore, in the present embodiment, the ion generator 13 cannot generate a sufficient amount of ions due to the foreign matter, or the foreign matter is clogged in the air path and the air flow is hindered. It becomes difficult. For this reason, in the air conditioning apparatus 1 which concerns on this Embodiment, the deterioration of the capability of the air cleaning using ion is suppressed.

Next, another configuration example of the air conditioner 1 will be described. FIG. 8 is a schematic diagram illustrating another internal configuration example of the air-conditioning apparatus 1. In FIG. 8, the figure which looked at the inside of the air conditioning apparatus 1 from the front is shown, and the housing | casing 11 is shown with the cross section. The air flow is indicated by arrows. In the example shown in FIG. 8, a protrusion is provided on the inner surface facing one of the

ion generators

13, 13, and a protrusion is formed on the inner surface facing the other ion generator 13. Is not provided. The air that has flowed through the space sandwiched between the one ion generator 13 and the protrusion 17 and released the ions flows while accelerating from the bottom to the top. The air from which ions are released from the other ion generator 13 is accelerated by the inclination of the ion generator 13, but becomes a smaller-scale acceleration.

In the form shown in FIG. 8, the portion of the outlet 112 where the accelerated air flows out between the ion generator 13 and the protrusion 17 includes only one edge of the outlet 112 in a front view. Yes. From the part including the other edge of the outlet 112, air flows out at a lower speed. In a state where the air conditioner 1 is disposed at the end of the floor 51, the possibility that foreign matter will fall from a portion near the end of the floor 51 within the edge of the outlet 112 is low. Therefore, by arranging the air conditioner 1 such that the portion of the edge of the outlet 112 where the air flows out by small-scale acceleration is closer to the end of the floor 51 than the other portion, From falling into the air conditioner 1 is suppressed. Even if the foreign matter falls into the air conditioner 1, it is possible to prevent the foreign matter from being clogged in the air path by the air accelerated between the ion generator 13 and the protrusion 17. Therefore, also in this form, in the air conditioning apparatus 1, it becomes difficult for the malfunction by the fall of a foreign material to generate | occur | produce, and the deterioration of the air-cleaning capability using ion is suppressed.

In addition, in the above embodiment, although the form provided with the protrusion part 17 was shown, the form which is not provided with the protrusion part 17 may be sufficient as the air conditioning apparatus 1. FIG. Even if the protrusion 17 is not provided, since the ion emission surface 131 of the ion generator 13 is inclined downward, the air flowing from the bottom to the top is accelerated, and the trouble due to the fall of the foreign matter is unlikely to occur. Become. Further, the air conditioner 1 may be configured such that the distance between the inner side surfaces of the housing 11 is continuously narrowed from the bottom to the top. In this embodiment, even if the protrusion 17 is not provided, the air passing between the ion generator 13 and the inner surface of the housing 11 flows while accelerating from the bottom to the top. Moreover, in the above embodiment, although the form provided with two ion generator 13 was shown, the air conditioning apparatus 1 is the form provided with only one ion generator 13, or three ion generators 13. The form provided with the stand or more may be sufficient.

Further, the air conditioner 1 may be in a form in which the filling member 15 is not provided. Although the embodiment including the filling member 15 has higher efficiency of discharging the air containing ions from the outlet 112, even the air conditioner 1 that does not include the filling member 15 performs air cleaning using ions. It is possible to suppress the deterioration of the ability. Moreover, the air conditioning apparatus 1 may not include the air guide member 16. Even if the air conditioner 1 that does not include the air guide member 16 is provided with the air guide member 16, the air guide member 16 does not include the air guide member 16, although the air flowing in from the inlet 111 is more efficiently guided to the ion generator 13. Air cleaning using is possible.

In the present embodiment, the inlet 111 is formed on the bottom surface of the casing 11. However, the air conditioner 1 has the inlet 111 formed on the side surface of the casing 11. May be. Moreover, in this Embodiment, although the form which has the air blower 3 in the exterior of the air conditioning apparatus 1 was shown, the air conditioning apparatus 1 may be a form which equipped the inside with air blowing mechanisms, such as a fan. Two or more air conditioners 1 may be installed in one room.
