Description

  The present invention relates to a humidifier that humidifies a personal space.

  The configuration of a conventional humidifier of this type is as follows.

  That is, a main body case having an intake port and an exhaust port, and in the main body case, a blower unit and a humidifier unit are provided in a blower passage that blows air from the intake port to the exhaust port (for example, The prior literature similar to this is described in Patent Document 1 below).

Japanese Patent Laid-Open No. 62-172145

  The problem in the conventional example is that when the feeling of cold air is reduced in the humidifier that humidifies the personal space, the amount of humidification also decreases.

  When humidifying a personal space, it is humidified near a person and directly receives humidified air. Therefore, especially in winter, it is easy to feel a cold wind depending on the room temperature. In order to suppress the feeling of cold wind, the conventional object can reduce the feeling of cold wind by lowering the notch, reducing the amount of humidified air, and lowering the wind speed. However, since the amount of humidified air decreases, the amount of humidification also decreases.

  Then, this invention aims at suppressing the fall of the humidification amount accompanying reduction of a cool wind feeling.

  In order to achieve this object, the present invention provides a main body case having an air inlet and an air outlet, and an air blower and a humidifier in the air passage that blows air from the air inlet to the air outlet in the main body case. The air outlet is provided with a wind direction changing means for changing the wind direction, and the wind direction changing means is provided with a cool wind feeling adjusting means. The cool wind feeling adjusting means includes the first cool wind feeling and the second cool wind feeling. The first cold wind feeling has a first humidification amount at a first wind speed, and the second cold wind feeling has a second humidification amount at a second wind speed. The second wind speed is slower than the first wind speed, and the second humidification amount is larger than the first humidification amount.

  This achieves the initial objective.

  As described above, the present invention provides a main body case having an air inlet and an air outlet, and, in the main body case, an air blowing means and a humidifying means are provided in an air passage that blows air from the air inlet to the air outlet. The air outlet is provided with a wind direction changing means for changing the wind direction. The wind direction changing means is provided with a cold wind feeling adjusting means, and the cold wind feeling adjusting means can be adjusted to the first cold wind feeling and the second cold wind feeling. The first cold sensation has a first humidification amount at a first wind speed, the second cold sensation has a second humidification amount at a second wind speed, The second wind speed is slower than the first wind speed, and the second humidification amount is larger than the first humidification amount.

  That is, when a cold wind feeling is sensed by the first cold wind feeling, the second wind speed is slower than the first wind speed by switching to the second cold wind feeling by the cold wind feeling adjusting means, and the second humidification amount. Becomes larger than the first humidification amount. That is, since the wind speed of the humidified air is reduced, the feeling of cool air is reduced, and the amount of humidified air is increased, so that a decrease in the humidified amount can be suppressed.

(Embodiment 1)
As shown in FIGS. 1 and 3, the humidifier according to Embodiment 1 of the present invention is provided with a blower outlet 1 on the top surface of the substantially cylindrical main body case 3, and at the lower part of the rear side surface of the main body case 3. Is provided with an inlet 2. Inside the main body case 3, a blowing unit 5 is provided in a blowing path 4 that blows air from the inlet 2 to the outlet 1.

  As shown in FIGS. 2 and 3, the air outlet 1 is provided with a wind direction changing means 19 that is rotatable in the elevation direction. The wind direction changing means 19 includes a substantially flat first horizontal plate 20, a substantially flat second horizontal plate 21 disposed below the first horizontal plate 20, and a first The rear plate 22 is formed downward from the rear portion of the horizontal plate 20, and a plurality of connecting plates 23 that connect the first horizontal plate 20 and the second horizontal plate 21.

  The area of the first horizontal plate 20 is larger than the area of the second horizontal plate 21, and the first horizontal plate 20 and the second horizontal plate 21 are positioned substantially in parallel. The second horizontal plate 21 is located below the first horizontal plate 20, near the tip of the first horizontal plate 20, that is, on the front side in the main body case 3.

  Among the plurality of connection plates 23, the connection plates 23 positioned at both ends of the second horizontal plate 21 are provided with shaft portions 24 that extend in the outward horizontal direction from the outer surfaces of these connection plates 23. .

  The wind direction changing means 19 is attached to the air outlet 1 through these shaft portions 24 so as to be rotatable in the elevation angle direction.

  The blowing means 5 is formed of a scroll-shaped casing 6, an electric motor 7 provided in the casing 6, and a sirocco fan 8 that is rotated by the electric motor 7. A suction port 9 is provided on the side surface of the casing 6, and a discharge port 10 is provided on the top surface of the casing 6. Humidifying means 11 is provided between the inlet 9 of the casing 6 and the inlet 2 of the main body case 3.

  The humidifying means 11 is disposed in the lower part of the main body case 3 and has an upper surface opened, a water storage container 12 for storing water at a constant water level, and a lower part immersed in the water storage container 12 from the upper surface opening. The humidifying filter 13 is made. A fixed amount of water is supplied to the water storage container 12 by a water supply tank 14.

  The air in the room sucked from the air inlet 2 passes through the humidifying filter 13 of the humidifying means 11 by the air blowing means 5 and the air is humidified. The humidified air is blown into the room through the blowing means 5, the air outlet 1, and the wind direction changing means 19, thereby humidifying the room. Here, when humidifying the personal space, the air is humidified near a person and the humidified air is directly blown to the person. As an example, a humidifier is placed on a desk and humidified air is blown directly toward the face of a sitting person.

  The feature in this embodiment is that the cool air feeling adjusting means 15 is provided in the air direction changing means 19 of the air outlet 1. The cold wind feeling adjusting means 15 can be adjusted to a first cold wind feeling and a second cold wind feeling. This first cold wind feeling has a first humidification amount at the first wind speed, and the second cold wind feeling has a second humidification amount at the second wind speed. Here, the second wind speed is slower than the first wind speed, and the second humidification amount is larger than the first humidification amount.

  That is, when the personal space is humidified, humidification is performed near the person and the humidified air is blown directly to the person. Therefore, when the first feeling of cold air is felt, the cold air feeling adjusting means 15 Thus, by switching to the second cold wind feeling, the second wind speed is slower than the first wind speed, and the second humidification amount is larger than the first humidification amount. That is, since the wind speed of the humidified air is reduced, the feeling of cool air is reduced, and the amount of humidified air is increased, so that a decrease in the humidified amount can be suppressed.

  The cool wind feeling adjusting means 15 can change the air blowing range. Specifically, as shown in FIGS. 3 to 5, the cool wind feeling adjusting means 15 includes a rectangular tube-shaped tube portion 16, a first opening 17 on one side of the tube portion 16, and the tube portion 16. It has the 2nd opening part 18 of the other side, and can be attached or detached to the blower outlet 1. FIG. Here, the opening area of the first opening 17 on one side is smaller than the opening area of the second opening 18 on the other side. That is, the upper surface portion 25 and the lower surface portion 26 of the tubular portion 16 having a rectangular tube shape are such that the first horizontal plate 20 and the second horizontal plate 21 of the wind direction changing means 19 are inclined inwardly from substantially parallel to each other. The left surface portion 27 and the right surface portion 28 of the cylindrical tube portion 16 are inclined inward from substantially parallel to the connecting plate 23 of the wind direction changing means 19. That is, the opening area of the first opening 17 on the downstream side in the air flow is smaller than the opening area of the second opening 18 on the upstream side, and the second opening 18 on the upstream side. The opening area of the first opening 17 gradually decreases and becomes the opening area of the first opening 17 on the downstream side. Thereby, it blows out so that it may gather in the central-axis direction of the cylinder part 16. As shown in FIG. A second opening 18 on the upstream side of the cylindrical portion 16 can be attached to and detached from the air outlet 1 via the wind direction changing means 19.

  That is, when the cylinder portion 16 is mounted on the air outlet 1 and operated, the humidified air blown upward from the air outlet 1 is applied to the lower surfaces of the first horizontal plate 20 and the second horizontal plate 21 that are the wind direction changing means 19. Since it flows along, the wind direction changes to the front side in the main body case 3. Then, by passing through the cylindrical portion 16, the opening area of the second opening portion 18 on the upstream side gradually decreases and becomes the opening area of the first opening portion 17 on the downstream side. It blows out to gather in the central axis direction. Thereby, the ventilation range which blows off from the 1st opening part 17 of the cylinder part 16 becomes smaller than the ventilation range which blows off from the blower outlet 1 mentioned later. In this state, the humidified air blown out has the first humidification amount at the first wind speed.

  Here, when a cold wind feeling is felt by the first cold wind feeling, the cylinder part 16 is removed from the wind direction changing means 19 of the air outlet 1 and used. Here, the upper surface portion 25 and the lower surface portion 26 of the tubular portion 16 of the rectangular tube shape are such that the first horizontal plate 20 and the second horizontal plate 21 of the wind direction changing means 19 are inclined inward from substantially parallel, Since the left surface portion 27 and the right surface portion 28 of the tubular portion 16 having a rectangular tube shape are inclined inward from substantially parallel to the connecting plate 23 of the air direction changing means 19, the air direction changing means 19 of the outlet 1 is Although the cylindrical portion 16 that is the cool wind feeling adjusting means 15 is blown out in substantially the same direction as when it is mounted, it is blown out from the air direction changing means 19 from the air blowing range that passes through the cylindrical portion 16 and blows out from the first opening 17. In this state, the humidified air blown out has a second humidification amount and a second humidification amount. That is, since the opening area of the wind direction changing means 19 is larger than the opening area of the first opening portion 17 and is blown out while expanding, the second wind speed is slower than the first wind speed. On the other hand, by removing the cylinder part 16 from the blower outlet 1, since ventilation resistance reduces and the amount of humidification air increases, the 2nd humidification amount becomes larger than the 1st humidification amount. As a result, by removing the cylinder part 16 from the blower outlet 1, the wind speed of the humidified air is reduced, so that the feeling of cold air is reduced and the amount of humidified air is increased, so that a decrease in the humidified amount can be suppressed. .

  The horizontal opening size of the first opening 17 on the downstream side of the cylindrical portion 16 is smaller than the horizontal opening size of the second opening 18 on the upstream side. On the other hand, the vertical opening size of the first opening portion 17 on the downstream side of the cylindrical portion 16 is smaller than the vertical opening size of the second opening portion 18 on the upstream side, and is on the upstream side. The opening area of the second opening 18 is gradually reduced to the opening area of the first opening 17 on the downstream side. Accordingly, the humidified air blown out from the first opening 17 on the downstream side of the cylindrical portion 16 is blown out so as to collect in the central axis direction of the cylindrical portion 16, and thus blown out from the first opening 17 of the cylindrical portion 16. The air blowing range blown out from the first opening 17 of the cylindrical portion 16 is smaller than the air blowing range.

  Here, the reduction ratio of the opening dimension from the upstream side to the downstream side in the air flow is such that the reduction ratio of the opening dimension in the vertical direction is larger than the reduction ratio in the opening dimension in the horizontal direction. That is, the vertical cross-sectional shape with respect to the air flow blown out by mounting the cool wind feeling adjusting means 15 is a horizontally long rectangular shape, and the reduction ratio of the opening dimension from the upstream side to the downstream side in the air flow is: The vertical opening dimension is larger than the horizontal opening dimension.

  Thereby, when humidifying a personal space, since humid air is blown directly to a person, the cylinder portion 16 is removed from the outlet 1 and used when the first cold air feeling is felt. As a result, the air blowing range blown out from the wind direction changing means 19 is larger in the rate of spreading in the vertical direction than in the horizontal direction as compared with the air blowing range blown out from the second opening 18 of the cylindrical portion 16. In other words, when humidifying a personal space, humidify near a person and blow humidified air directly to the person. If a feeling of cold air is felt by the first cold air feeling, Rather than concentrating on the part, the blowing range can be expanded to the whole body. In particular, when a humidifier is placed on the desk and the humidified air is blown directly toward the face of the person sitting, the blowing range is expanded in the vertical direction, so that the blowing range is expanded over the entire upper body, The wind speed of the humidified air in the personal space is reduced, the feeling of cool air is reduced, and the amount of humidified air is increased, so that a decrease in the humidified amount can be suppressed.

  As described above, the present invention provides a main body case having an air inlet and an air outlet, and, in the main body case, an air blowing means and a humidifying means are provided in an air passage that blows air from the air inlet to the air outlet. The air outlet is provided with a wind direction changing means for changing the wind direction. The wind direction changing means is provided with a cold wind feeling adjusting means, and the cold wind feeling adjusting means can be adjusted to the first cold wind feeling and the second cold wind feeling. The first cold sensation has a first humidification amount at a first wind speed, the second cold sensation has a second humidification amount at a second wind speed, The second wind speed is slower than the first wind speed, and the second humidification amount is larger than the first humidification amount.

  That is, when a cold wind feeling is sensed by the first cold wind feeling, the second wind speed is slower than the first wind speed by switching to the second cold wind feeling by the cold wind feeling adjusting means, and the second humidification amount. Since it becomes larger than the first humidification amount, the wind speed of the humidified air is reduced, so that the cool air feeling is reduced and the humidified air amount is increased, so that the decrease in the humidification amount can be suppressed.

  Therefore, it is expected to be used as a humidifier for home use or office use.
