Patent Publication 2002-96890

  When considering installing a fan in a bedroom or a washroom as well as in a living room, for example, it is not necessary to use a fan installed in the living room at bedtime, or the usage time of a fan installed in a washroom is Although it is assumed that the fan is short, it is not practical to move the fan for use in a bedroom, for example, because a fan that is mainly used in a living room is large or heavy. As a result, it is difficult to secure storage space because it is necessary to purchase multiple small fans that are supposed to be used in bedrooms and children's rooms, etc. in addition to their use in living rooms. Yes.

Means for solving the idea

  In the connected fan according to the first aspect of the present invention, in the fan having a plurality of blower units, each blower unit has a power input unit and a power output unit, and receives a power input from another blower unit or an external power supply. By having a structure capable of blowing air and outputting the power supply from the power supply output unit, any number of blower units can be connected and used in the vertical or horizontal direction, and each blower can be used. A connected fan that can be used alone with the unit removed.

  Each blower unit has a structure for receiving power directly or indirectly, and each blower unit has a mechanism for performing part or all of control such as adjustment of power supply, air volume, or automatic stop function by a timer. The connected fan according to claim 1, wherein the blower unit can be used alone and can be controlled for each blower unit when connected.

  It has a control unit with a structure that can connect and connect the blower unit, and when the blower unit is connected, part or all of the control, such as adjustment of power supply and air volume or automatic stop function by timer, is performed centrally. The connected electric fan according to claim 1, wherein the electric fan is made possible.

  When connecting and connecting the blower units in the vertical direction, it can be fixed or freely rotated at any angle left and right or up and down with respect to the horizontal axis with respect to the vertical axis. The connected fan according to claim 1, wherein air can be blown in a state in which each blower unit is directed in a different direction.

  In the connection connection of each blower unit or the connection connection between the blower unit and the control unit, the power supply input part and the power supply output part have one convex shape and one concave shape with respect to the connection surface. If the connection is in the vertical direction, the concave part for position definition protrudes toward the convex side of the power input part or power output part on one of the left and right side surfaces if the connection is horizontal. And the convex shape of the power input part or power output part is controlled by the blower unit or control by setting the depth of the position defining concave part deeper than the height of the convex shape of the power input part or power output part. The connected fan according to claim 1, wherein the connected fan is prevented from projecting out from the unit and being damaged during connection and storage.

Effect of device

  In the connected fan of the present invention according to claim 1, a fan composed of a plurality of blower units is used to connect a plurality of blower units to a large type used in a living room or the like, and the blower unit is removed and used alone. It can be used as a small type used in bedrooms, etc., so not only can one fan be divided into multiple units and used simultaneously, but also each fan unit can be removed and stored for storage I can do it.

  In the coupled fan of the present invention according to claim 2, when the blower unit is used alone, the blower unit has a control unit, so that functions such as air volume adjustment and timer function can be used even in a bedroom. Can have.

  In the coupled fan of the present invention according to claim 3, when the blower unit is coupled and used, by providing a control unit that concentrates functions such as air volume adjustment and timer function, a user operation method is provided. Can be made easier.

  In the coupled fan of the present invention according to claim 4, when the blower unit is connected and used, it is possible to send the wind to a wider range by arbitrarily changing the mounting direction of the blower unit.

  The connected fan of the present invention according to claim 5 is such that the power input part or power output part of the blower unit or the control unit has one convex shape and one concave shape with respect to the connection surface. Or by making it the structure which does not protrude from a control unit, the damage at the time of a connection or accommodation can be prevented.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic structural diagram of a connecting portion of a connecting fan according to an embodiment of the present invention, and FIG. 1 (A) is a structural diagram when two a blower units are connected to a b control unit in a vertical direction. FIG. 4B is an enlarged view of the inside of the air blowing unit.

  In FIG. 1 (B), when the power input from the b power input unit disposed on the lower surface of the a blower unit is branched by the e internal wiring, on the other hand, the f motor is driven to rotate the g fan to blow air. At the same time, on the other hand, the power is sent to the power output unit c arranged on the upper surface of the air blowing unit.

In FIG. 1B, branching is performed by e internal wiring, but as a branching method, for example, a terminal block is used or a control board for adjusting the air volume is used. Is also possible.

  In FIG. 1 (A), by connecting a blower unit, power is supplied from a c power supply input part arranged on the upper surface of one a blower unit to a b power supply input part arranged on the lower surface of the other a blower unit. It becomes possible to send.

  Power supply from the outside can be directly input to the lowermost a blower unit. However, as shown in FIG. 1 (A), the d control unit is placed at the lowermost position and power supply is performed at the same time. It is possible to control the entire connected a blower unit.

  FIG. 2 is an overall conceptual diagram of a connected fan according to an embodiment of the present invention. FIG. 2A shows a state in which three a blower units are connected and connected on a d control unit. ) Is a conceptual diagram in which one a blower fan in FIG. 3A is removed, and the remaining two a blower units and d control unit and the removed a blower unit are connected to the h small control unit.

  In FIG. 2B, the removed a blower unit is connected to the d small control unit, but it is also possible to use the a blower unit alone without being connected to the d small control unit.

  FIG. 3 is a conceptual diagram of the connection direction of the connecting fan according to the embodiment of the present invention. For example, when three a blower units are connected, the direction of the blow is changed for each a blower unit by changing the connection direction. It can be changed and installed.

  1, 2, and 3, the shape of a vertical fan using a crossflow fan is described as an example as an embodiment. However, by changing the shape of the fan with a similar structure, for example, It is also possible to connect a circular fan having a round blower portion or to connect it horizontally.
