Abstract

The present invention provides a humidifier capable of preventing water generated by dew condensation of vapor from being combined with air, so that an air humidity can be stably controlled. A humidifier according to the present invention includes a storage tank that stores water, the storage tank being opened upward, a heater that heats the water in the storage tank, and a guide plate that is disposed above the storage tank, on at least one of one side and the other side in a first direction extending along a horizontal direction with respect to a center of the storage tank. The guide plate extends in an inclined manner such that an upper part thereof is positioned closer to the center of the storage tank in the first direction than a lower part thereof.

First claim

The invention claimed is:

1. A humidifier comprising:
a storage tank that stores water, the storage tank being opened upward;
a heater that heats the water in the storage tank; and
a guide plate that is disposed above the storage tank, on at least one of one side and the other side in a first direction extending along a horizontal direction with respect to a center of the storage tank,
wherein the guide plate extends in an inclined manner such that an upper part thereof is positioned closer to the center of the storage tank in the first direction than a lower part thereof, and
wherein the guide plate is open on both sides in a second direction that is orthogonal to the first direction in a horizontal plane.

2. The humidifier according to claim 1 , wherein the guide plate has an inclined side part that is positioned such that, in a top view, an end thereof, which is on one side of the second direction that is orthogonal to the first direction in the horizontal plane, is more distant from the center of the storage tank in the first direction than an end thereof that is on the other side of the second direction.

3. The humidifier according to claim 2 , wherein a second side part of the guide plate faces the other side of the second direction in the horizontal plane, and
wherein, in a top view, the second side part extends along the first direction.

4. The humidifier according to claim 3 , wherein a wall part of the storage tank on the other side of the second direction extends along the first direction, and
wherein in a top view, the second side part is overlapped with the wall part or is positioned outside the wall part.

5. The humidifier according to claim 3 , wherein the second side part is provided with a projection that projects downward and extends along the second side part.

6. The humidifier according to claim 1 , wherein the guide plate is disposed such that, in a top view, a gap is defined between the guide plate and a wall part of the storage tank on a side on which the guide plate itself is positioned in the first direction.

7. The humidifier according to claim 1 , wherein the guide plate is disposed on both the one side and the other side of the first direction, with respect to the center of the storage tank, and
wherein a pair of the guide plates are symmetric with reference to a vertical plane that passes the center of the storage tank in the first direction and extends along the second direction that is orthogonal to the first direction.

8. The humidifier according to claim 1 , wherein the humidifier is configured to be disposed in an air conditioner comprising an air flow path through which air flows, and a plate installed in a downstream opening of the air flow path, the plate being provided with an air through hole, wherein the air flow path includes a horizontal channel, the horizontal channel being provided with the downstream opening and extending along the horizontal direction, such that the humidifier is installed on the horizontal channel, and
wherein the humidifier is configured to be installed such that the second direction that is orthogonal to the first direction in the horizontal plane is along an extension direction of the horizontal channel, and that a part of the guide plate is disposed to be overlapped with the air through hole when viewed along the second direction.

9. The humidifier according to claim 1 , wherein the humidifier is configured to be disposed in an air conditioner comprising an air flow path through which air flows, and a plate installed in a downstream opening of the air flow path, the plate being provided with an air through hole, wherein the air flow path includes a horizontal channel, the horizontal channel being provided with the downstream opening and extending along the horizontal direction, such that the humidifier is installed on the horizontal channel, and
wherein the humidifier is configured to be installed such that the second direction that is orthogonal to the first direction in the horizontal plane is along an extension direction of the horizontal channel, and that an extension line of the guide plate is disposed to pass a center of the air through hole when seen along the second direction.

10. An air conditioner comprising:
an air flow path through which air flows;
a plate installed in a downstream opening of the air flow path, the plate being provided with an air through hole; and
a humidifier disposed on the air flow path and capable of supplying vapor into the air flow path;
wherein the air flow path has a horizontal channel provided with the downstream opening and extending along a horizontal direction,
wherein the humidifier is disposed on the horizontal channel,
wherein the humidifier has
a storage tank that stores water, the storage tank being opened upward,
a heater that heats the water in the storage tank, and
a guide plate that is disposed above the storage tank, on at least one of one side and the other side in a first direction extending along a horizontal direction with respect to a center of the storage tank, the guide plate extending in an inclined manner such that an upper part thereof is positioned closer to the center of the storage tank in the first direction than a lower part thereof, and

wherein the humidifier is configured to be installed such that a second direction, which is orthogonal to the first direction in a horizontal plane, is along an extension direction of the horizontal channel.

11. The air conditioner according to claim 10 , wherein the guide plate has an inclined side part that is positioned such that, in a top view, an end thereof, which is on one side of the second direction orthogonal to the first direction in the horizontal plane, is more distant from the center of the storage tank in the first direction than an end thereof, which is on the other side of the second direction, and
wherein the plate is positioned on the other side of the second direction with respect to the humidifier.

12. The air conditioner according to claim 11 , wherein a second side part of the guide plate faces the other side of the second direction, and
wherein the second side part extends along the first direction.

13. The air conditioner according to claim 12 , wherein a wall part of the storage tank on the other side of the second direction extends along the first direction, and
wherein in a top view, the second side part is overlapped with the wall part or is positioned outside the wall part.

14. The air conditioner according to claim 12 , wherein the second side part is provided with a projection that projects downward and extends along the second side part.

15. The air conditioner according to claim 12 further comprising:
a moisture absorption member that extends in an up and down direction, above a wall part of the storage tank on the other side of the second direction, or diagonally thereabove on the other side of the second direction.

16. The air conditioner according to claim 10 , wherein the guide plate is disposed such that, in a top view, a gap is defined between the guide plate and a wall part of the storage tank on a side on which the guide plate itself is positioned in the first direction.

17. The air conditioner according to claim 10 , wherein when seen along the second direction, a part of the guide plate is overlapped with the air through hole.

18. The air conditioner according to claim 10 , wherein when seen along the second direction, an extension line of the guide plate passes a center of the air through hole.
