Description

Air supply device

The present invention relates to a blower. The air-supplying device refers to a device that sucks air from a suction port and blows air from a blow-out port with some treatment or no treatment other than pressurization. For example, dehumidifiers, humidifiers, air conditioners, circulators, air coolers, electric heaters, and electric fans are suitable for the air supply device.

Dehumidifiers and humidifiers have been proposed that can change the direction of the wind (air) blown from the air outlet. Such a dehumidifier is disclosed in Patent Document 1, for example.

In the dehumidifier of Patent Document 1, the cover body located at the upper center portion of the main body is arranged to be rotatable relative to the main body by a motor. The lid has an opening portion that opens upward, and a blow-out nozzle is provided in the opening portion. The blow-out nozzle has a mechanism that can move up and down. With the movable cover body and blowing nozzle, the dehumidifier can supply dehumidified wind in a wide range.

However, the dehumidifier of Patent Document 1 cannot supply the wind directly below or horizontally than the blowout nozzle. The dehumidifier is rotating The cover is arranged in the center, and the blow-out nozzle is provided on the cover. Therefore, the blow-out nozzle is arranged upward from the cover, and the blow-out nozzle cannot be moved downward or horizontally.

A humidifier capable of changing the direction in which the wind is blown is disclosed in Patent Document 2.

The humidifier of Patent Document 2 includes a main box and an airflow direction changing unit disposed on an upper portion of the main box. The wind direction changing portion constitutes the outermost peripheral portion and can be manually rotated relative to the main body case. In addition, the wind direction changing part has a local blowout port for blowing out humidified air on a side surface thereof.

However, in the humidifier of Patent Document 2, since the rotation of the wind direction changing section is performed manually, the user can only supply wind with a fixed wind direction in a narrow range without changing the wind direction by the user. Therefore, it is impossible to efficiently humidify the entire house to various corners.

Patent Document 2 Japanese Patent Application Publication No. 2014-20707

An object of the present invention is to provide a supply air that can supply wind even in a downward direction or a horizontal direction, in addition to supplying wind in a wide range of directions in a circumferential direction (a rotation direction centered on an axis). Device.

The present invention provides a blower device including a main body portion having a suction port and a blower means, and a rotating portion disposed above the main body portion and arranged so as to be able to face the axis around the axis by the first driving means. The main body part rotates, and a side of the rotating part is provided with an air outlet that blows air sucked from the inlet through the air blowing means in a direction crossing the axis.

According to this air blowing device, the air outlet is arranged on the side of the rotating portion that is rotated by the first driving means, thereby supplying various wind directions in a wide range in addition to the circumferential direction (the rotation direction around the axis) to supply the wind. In addition, the wind can be supplied even in a downward or horizontal direction. Therefore, the wind can be supplied to every corner of the room, and even the wind can be supplied to a specific location.

It is preferable that the blower is an ejection range of the air emitted from the air outlet, and includes a range of ± 180 ° from a reference position when viewed from a direction in which the axis extends.

According to this air supply device, since the emission range of the air (wind) from the air outlet includes a range of ± 180 °, the wind can be supplied to the entire range in the circumferential direction, and the wind can be supplied to every corner of the room.

Preferably, the rotating portion is rotatably disposed around the axis with respect to the fixing portion fixed to the body portion, the fixing portion has at least one receiving portion, and the rotating portion has at least one corresponding portion. When the abutting portion of the receiving portion is rotated to the rotation limit, the abutting portion and the abutting portion are in contact with each other to restrict the rotation of the rotating portion.

According to this air blowing device, the rotation mechanism of the rotating part including the range of ± 180 ° (or to the rotation limit) from the reference position can be realized with a simple structure without the need for additional parts, and can be reliably performed. The rotation of the rotating portion is substantially limited to a range of ± 180 ° (or a rotation limit). Here, the range of substantially ± 180 ° refers to a range in which an error between thicknesses of the receiving portion and the abutting portion is considered. In other words, the actual rotation angle range is a range smaller than the range of ± 180 degrees in the thickness of the receiving portion and the abutting portion. Even in this case, since the emission range of the wind is wider than the actual rotation angle because it can be diffused, it can include ± 180 degrees.

Preferably, the receiving portion is provided with a first receiving portion and a second receiving portion at positions of different heights, and the abutting portion is provided with a first abutting portion disposed at the same height as the first receiving portion, and an arrangement In the second abutting portion having the same height as the second receiving portion, when the rotating portion rotates to a rotation limit, the first receiving portion and the first abutting portion abut, the second receiving portion and the second abutting portion. The abutting portion abuts to restrict rotation of the rotating portion.

According to this air blower, by providing two receiving portions and abutting portions, it is possible to more reliably prevent the abutting portion from overriding the receiving portion when the rotating portion is rotated, as compared with a case where each receiving portion is provided.

Preferably, the blade driven by the second driving means is disposed at the blow-out port.

According to this air blowing device, since the air outlet has blades movable by the second driving means, the air can be supplied from the air outlet in various directions. In particular, it is possible to supply wind of various wind directions in a wide range by rotating the blower outlet together with the rotating portion.

Preferably, the air treatment members are arranged on both sides in the air outlet.

According to this blower, not only the supply of air but also the treatment of the blown air can be performed simultaneously. Air treatment refers to sterilization, deodorization, and aroma. In addition, by arranging both sides in the air outlet, air having a relatively high flow velocity that is blown from the center side of the air outlet can pass through the air outlet without affecting the flow velocity. Therefore, it is possible to prevent a decrease in the amount of blown air compared to the case where the air processing member is arranged in the center.

According to the present invention, the air outlet is disposed on the side of the rotating portion that is rotated by the first driving means, so that various wind directions can be changed in a wide range in addition to the circumferential direction (the rotation direction around the axis) to supply the In addition, the wind can be supplied even in a downward or horizontal direction.

FIG. 11A is a front view as viewed from the air outlet when the air blowing section 640 is located at the position shown in FIG. 8A. As shown in FIG. 11A, the first receiving portion 684 and the first abutting portion 686 abut, and the second receiving portion 685 and the second The abutting portion 687 abuts. Thereby, the rotation of the blower part 640 is restricted to substantially not more than + 180 °.

FIG. 11C is a front view as viewed from the air outlet when the air blowing section 640 is located at the position shown in FIG. 8C. As shown in FIG. 11C, the first receiving portion 684 and the first abutting portion 686 abut, and the second receiving portion 685 and the second The abutting portion 687 abuts (see FIG. 11C). Thereby, the rotation of the ventilation part 640 is restricted so that it may not substantially exceed -180 degrees.

The receiving sections 684 and 685 and the abutting sections 686 and 687 are respectively provided The reason why the two are provided is because it is possible to more reliably prevent the abutting portions 686 and 687 from overtaking the receiving portions 684 and 685 as compared with the case of each one. Therefore, each of the receiving portions 684 and 685 and the abutting portions 686 and 687 may be one each (the first receiving portion 684 and the first abutting portion 686 or the second receiving portion 685 and the second abutting portion 687). Furthermore, in the present embodiment, the receiving portions 684 and 685 and the abutting portions 686 and 687 are formed in a convex shape, respectively, but they are not limited to this as long as they have corresponding shapes. For example, the abutting portions 686 and 687 may have a convex shape, and the receiving portions 684 and 685 may have a corresponding groove shape. This corresponds to the shape of the groove.

Blowing section 640 from the reference position in the circumferential direction P _R A substantially ± 180 degrees of rotation, and is arranged pivotable in the vertical direction B, the blade 660 outlet portion 642 is provided at a side portion of the blower 640, whereby the circumferential direction and can be A Various winds are blown in the vertical direction B. Therefore, it is possible to supply wind by changing various wind directions in a wide range, and it is possible to supply wind to every corner of the room, and it is also possible to supply wind to a specific position.

12A and 12B are a perspective view and a front view of the rotating body portion 650. As shown in FIGS. 12A and 12B, the air treatment member 690 may be disposed near the air outlet 642. As a result, not only the dehumidification of the treated air, but also the treatment of the blown air can be performed simultaneously. Air treatment refers to sterilization, deodorization, and aroma. The air treatment member 690 is a porous material containing a ceramic material, and although it does not completely block the flow of air, it is a resistance to the flow when there is a flow path of the air. The air treatment member 690 has two central openings for opening the air outlet 642 arranged on both sides. With such a configuration, the processing air having a relatively high flow velocity which is blown out from the central side of the blow-out port 642 can pass through the blow-out port 642 without being affected by the flow rate. Therefore, it is possible to prevent a decrease in the blow-out amount of the processing air compared to a case where the air processing member 690 is arranged in the center.

(Second Embodiment)

Fig. 13 is a conceptual sectional view showing a dehumidifier 1 according to a second embodiment. The structure of the dehumidifier 1 according to this embodiment is the same as that of the first embodiment shown in FIG. 4 except for a part of the top portion 600. Therefore, the same parts as those in the structure shown in FIG. 4 are given the same reference numerals, and descriptions thereof are omitted.

As shown in FIG. 13, the dehumidifier 1 according to this embodiment is different from the first embodiment and does not include a top base 610 and a storage box 680. Therefore, in the present embodiment, the air blowing section 640 constituting the rotating section of the present invention is disposed above the main body 100 and is rotatable relative to the main body 100. In addition, the top base 610 may be integrally formed on the upper surface of the main body 100, for example.

With this configuration, in this embodiment, compared with the first embodiment, the number of parts can be reduced and a simple structure can be realized.

In addition, the dehumidifier 1 includes, for example, indoor air as a dehumidification target, and also includes moisture on clothes as a dehumidification target for drying clothes, or both of these purposes.

Furthermore, although the dehumidifier is taken as an example to explain the present invention, the present invention can also be applied to a humidifier, an air conditioner, a circulator, and a cold air. Fans, heaters, and fans other than dehumidifiers.
