A main body provided behind the blade housing;
A fan having a support leg provided at a lower portion of the main body,
The blade housing portion includes a cylindrical main body, and a first operation portion is provided on an outer peripheral side surface of the cylindrical main body.

  The operation and effects of the fan having such a configuration will be described. The fan includes a blade housing portion in which a blowing blade is housed, the blade housing portion includes a cylindrical main body, and a first operation portion is provided on an outer peripheral side surface thereof. That is, the operation unit is not disposed on the base at the lower end of the support leg portion, but is disposed on the blade housing portion. Therefore, it is possible to operate without making a large bend on the body, and the operability is improved. As a result, a fan with improved operability can be provided.

  It is preferable that the cylindrical main body according to the present invention has a front edge which is continuous with the outer peripheral side, and a second operation portion is provided on the front edge.

  According to this configuration, the second operation portion is provided on the front edge portion of the cylindrical main body of the blade housing portion. Therefore, the operation unit necessary for the fan can be divided into the first operation unit and the second operation unit.

  Preferably, the first operation unit according to the present invention is a dial-type operation unit. Ergonomically, the first operation portion on the outer peripheral side can be easily operated by making it dial-type.

  The second operation unit according to the present invention is preferably a button type operation unit. Ergonomically, the second operation unit disposed in front can be easily operated by using a button type.

  It is preferable that the dial-type operation unit according to the present invention is disposed at the same height as the rotation center of the blower blade. With this configuration, it is possible to operate the operation unit in a reasonable posture.

  It is preferable that the second operation unit according to the present invention is disposed adjacent to the first operation unit. Thereby, the first operation unit and the second operation unit can be operated in the same posture.

  A preferred embodiment of a fan according to the present invention will be described using the drawings. FIG. 1 is a front view of a fan according to the present embodiment. FIG. 2 is also a side view. FIG. 3 is also a rear view. FIG. 4 is a central longitudinal sectional view.

  As shown in FIG. 1 and FIG. 2 etc., the fan according to the present invention comprises a fan blade 1 which is rotationally driven, a blade housing 2 in which the fan 1 is accommodated, and a front opening of the blade housing 2. The blade guard 3 is provided to close the unit. The blower blade 1 has seven blades, but the number and shape of the blades are not limited to a specific one. The blade guard 1 is detachably attached to the blade housing 2.

  The blade housing 2 has a ring-shaped cylindrical main body, and has an outer peripheral side surface 20, a front edge 21, and a rear surface edge 22. The front edge 21 is in the shape of a ring having a predetermined width, and the wing guard 3 is provided on the inside thereof. The rear edge 22 is also in the form of a ring having a predetermined width, and is provided with the rear blade guard 7 inside thereof. The outer circumferential side surface 20, the front edge 21 and the rear edge 22 are integrally formed of resin.

  A main body 4 is provided at the rear of the rear blade guard 7 (blade housing 2), and a motor for rotating the blower blades 1, other drive circuits, and a control circuit are disposed. Handles 8 are provided in the main body portion 4 and supported by the left and right side surfaces of the main body portion 4 so as to be rotatable around the shaft core 8 a. By rotating the handle 8 around the shaft core 8 a and moving the handle 8 upward, the fan 8 can be carried by hand.

  A support leg 5 is provided below the main body 4. The support leg portion 5 is configured by combining a plurality of vertical rod-like members, and the length can be adjusted by expanding and contracting. A base 6 is attached to the lower end of the support leg 5. The telescopic mechanism may be of known construction.

  As shown in FIG. 4, a drive motor 40 for driving the blower blade 1 and a power supply circuit and a control circuit (not shown) are disposed inside the main body 4.

  FIG. 5 is a partially enlarged perspective view of the operation unit. FIG. 6 is a partially enlarged front view of the operation unit. The operation unit is an operation dial 23 (corresponding to a first operation unit) disposed on the outer peripheral side surface 20 of the cylindrical main body, and a button group 24 (corresponding to a second operation unit) disposed on the front edge 21 of the cylindrical main body. And). The operation dial 23 can rotate around a horizontal axis, and the height of the rotation center is the same height as the rotation center of the blower blade 1.

  The button group 24 includes a first button 24a, a second button 24b, and a third button 24c. The button group 24 is a touch switch type operation unit and can be touched from the front side. The button group 24 is disposed in the vicinity of the operation dial 23 and the height is also substantially the same as that of the operation dial 23. In particular, the middle second button 24 b is located at the same height as the operation dial 23.

  The operation dial 23 has a function of power ON / OFF and a function of air volume adjustment. The first button 24a has a function of swinging left and right, the second button 24b has a setting of an ON / OFF timer, and the third button 24c has a function of setting a rhythm / night time mode.
