Description

  The present invention relates to a blower. The blower device refers to a device that sucks air from the suction port and blows out air from the air outlet without applying any processing or processing other than pressurization. For example, a dehumidifier, a humidifier, an air conditioner, a circulator, a cold air fan, a hot air fan, an electric fan, etc. correspond to an air blower.

  Conventionally, a dehumidifier and a humidifier that can change the direction in which wind (air) blows out from an air outlet have been proposed. For example, this type of humidifier is disclosed in Patent Document 1.

  The humidifier of Patent Literature 1 includes a main body case and a wind direction changing unit disposed on the upper portion of the main body case. The wind direction changing unit is rotatable with respect to the main body case. Moreover, a wind direction change part has the blower outlet for spots for blowing the humidified air on the side surface.

  However, in the humidifier of Patent Document 1, when the wind direction changing portion rotates with respect to the main body case, the wind direction changing portion slides on the upper surface of the main body case, so that rotation between the main body case and the wind direction changing portion is caused by friction. There is a drag that prevents it.

The sliding resistance can also be reduced by sliding the.

  It is preferable that the first contact portion and the urging means are disposed in the rotating portion, and the first receiving surface is disposed in the main body portion.

  According to this blower, the first abutting portion and the urging means are arranged on the rotating portion, so that the urging of the first abutting portion by the urging means becomes easy. Specifically, since the rotating part is above the main body part, the urging means urges the first abutting part downward by providing the first abutting part and the urging means on the rotating part side. To do. Therefore, since the gravity direction and the urging direction coincide with each other, the urging force can be reduced compared to the case where the first contact portion and the urging means are provided on the main body side, and the urging is facilitated.

  The rotating portion has a through hole, and further includes a fixed top portion disposed at least partially in the through hole with a gap between the rotating portion, and an inner side of the through hole and the fixed top portion. It is preferable that one of them includes a second receiving surface, and the other of the inside of the through hole and the fixed top portion includes a second contact portion that contacts the second receiving surface.

  According to this blower, the rotational resistance of the rotating part can be reduced by providing the second contact part. Further, the movable range in the horizontal direction (direction intersecting the axis) of the rotating part can be restricted by the second rolling element and the second receiving surface coming into contact with each other.

  The second contact portion is preferably a part of a second rolling element that rolls on the second receiving surface.

  Since the second contact portion is a part of the second rolling element, the rotational resistance of the rotating portion can be further reduced. Here, the second rolling element includes a ball type having no shaft in addition to a wheel type having a shaft.

  ADVANTAGE OF THE INVENTION According to this invention, in the air blower which has a rotation part, while being able to reduce the rotation resistance of a rotation part, the damage when an excessive force is added to an axial direction with respect to an apparatus can be prevented.

When a pressing force of a predetermined level or more is applied, the first roller 691 moves upward together with the holding casing 692 by bending the leaf spring 693. As a result, the first roller 691 is accommodated in the attachment portion 653 together with the holding casing 692. At this time, the upper surface 633 of the base cover 630 is in contact with the stopper 655 of the mounting portion 653, and a pressing force exceeding a predetermined value is not applied to the first roller 691. By doing in this way, damage, such as a shaft break of the 1st roller 691, can be prevented.

  Further, as shown in FIGS. 7 and 10A and 10B, the stopper 655 of the mounting portion 653 is a flat surface. Accordingly, when the first abutting portion 691a of the first roller 691 is pressed upward from the upper surface 633 of the base cover 630 with a pressing force of a predetermined level or more, the stop portion 655 of the mounting portion 653 is the base cover. The load at the time of contact received from the upper surface 633 of 630 can be distributed. Therefore, damage to the attachment portion 653 and the base cover 630 can be prevented.

  FIG. 11A is a perspective view of the rotating main body 650. FIG. 11B is a partially enlarged view of FIG. 11A. As shown in FIGS. 11A and 11B, a plurality of second rollers (second rolling elements) 696 are disposed on the upper part of the inflow portion 651 in the rotating main body portion 650. In the present embodiment, six second rollers 696 are arranged at equal intervals around the inflow portion 651 at an equal distance from the axis L. The second roller 696 has its axis disposed in the same direction as the axis L, and includes a second contact portion 696a. The second contact portion 696a is a side surface (second receiving surface) of the cover panel 682. ) Is in contact with 683. Accordingly, when the rotating main body 650 is rotated, the second roller 696 rotates on the side surface 683 of the cover panel 682, and the frictional resistance between the rotating main body 650 and the cover panel 682 is reduced. Further, the movable range of the blower 640 in the horizontal direction (direction intersecting the axis L) can be restricted by the second roller 696 and the side surface 683 of the cover panel 682 coming into contact with each other.

(Second Embodiment)
12A and 12B are cross-sectional views of the roller unit 690 and the mounting portion 653 showing the first roller 691 before and after the movement according to the second embodiment. The dehumidifier 1 of this embodiment is the same as that of 1st Embodiment of FIG. 10A and FIG. 10B except the part relevant to the roller unit 690 and the attaching part 653. FIG. Therefore, the same components as those shown in FIGS. 10A and 10B are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIGS. 12A and 12B, the dehumidifier 1 of the present embodiment is different from the first embodiment in that the attachment portion 653 does not include the stop portion 655 and stops downward on the lower surface of the rotary main body portion 650. A portion 655 is disposed. Accordingly, when the first contact portion 691a of the first roller 691 is pressed upward from the base cover upper surface 633, the first roller 691 is displaced upward, and the stopper portion 655 contacts the base cover upper surface 633. . Accordingly, a pressing force equal to or greater than a predetermined force is not applied to the first contact portion 691a of the first roller 691, so that the first roller 691 can be prevented from being damaged.

(Third embodiment)
FIGS. 13A and 13B are sectional views of an abutment unit (roller unit) 690 and an attachment portion 653 showing the first abutment portion 691a before and after the movement according to the third embodiment. The dehumidifier 1 of this embodiment is the same as that of 1st Embodiment of FIG. 10A and 10B except the part relevant to the contact part unit 690 and the attaching part 653. FIG. Therefore, the same components as those shown in FIGS. 10A and 10B are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIGS. 13A and 13B, the dehumidifier 1 of this embodiment does not include the first roller 691 and the holding casing 692, unlike the first and second embodiments. Specifically, one end of the urging means 693 constitutes a first contact portion 691a, and the first contact portion 691a slides on the base cover upper surface 633. Accordingly, when the first contact portion 691a, which is one end of the biasing means 693, is pressed upward from the base cover upper surface 633 with a pressing force equal to or greater than a predetermined force, the first contact portion 691a is displaced upward.
