Problems solved by technology
However, since the connection terminal is inside the opening, it is difficult to put your hand in, so the operability is not good, and improvement is desired.
In addition, according to the above-mentioned prior art, there is a danger that the connection terminal will fall freely due to its own weight, and when the power cord is connected to the connection terminal, since the connection terminal is not fixed, it is difficult to insert the power cord into the power terminal. There is a problem that the connection terminal is retreated to the inner side, and it is difficult to carry out the connection construction of the power line.
In this way, if the electrical contact of the power cord is insufficient, not only will there be a safety problem, but it will also cause a fire, and improvement is desired.
In addition, if a VVF cable is used as a power supply line, the built-in copper wire is thick and hard, so there is another problem that if it is bent sharply during power supply connection construction, it will break and cause poor contact

Embodiment approach 1
[0037] figure 1It is a perspective view showing an embodiment of the blower of the present invention, figure 2 It is a front view seen from the blower outlet side, image 3 It is a front view seen from the suction port side of the blower. The blower 100 has an elongated cubic box-shaped outer case 1 constituting an outer case. An air outlet 2 and an air inlet 3 are formed on opposite surfaces of the outer case 1 . The blower outlet 2 is formed in upper and lower layers, such as figure 1 As indicated by the middle arrow A, air is blown out from each outlet 2 . The outer box 1 is installed, for example, so as to be suspended from a ceiling by means of mounting plates 7 provided at both end portions. In this embodiment, a pair of mounting plates 7 erected downward on the ceiling surface (not shown) pivotally support both ends of the outer case 1 so that both ends can rotate freely. figure 1 As shown by the middle arrow B, the outer case 1 rotates to change the wind directi...

The invention provides an air blower which is provided with an outer box, a mounting plate, blades, a motor, a terminal panel and a tension inhibition part. Sucking-in openings and blowing-out openings are formed in the outer box. The mounting plate is arranged on the side of the outer box in a matched mode and supports the outer box from a ceiling face or a wall face. The blades and the motor are stored in the outer box. The blades blow air towards the blowing-out openings from the sucking-in openings, and the motor drives the blades. The terminal panel is provided with a connecting terminal which enables a wire supplying power to the motor to be electrically connected with the motor. The tension inhibition part is arranged on the side face of the outer box, and the wire is clamped to enable tension acting on the wire not to be transmitted to the connecting terminal or to the connection portion of the connecting terminal and the wire. The supporting face, clamping the wire, of the tension inhibition part tilts in the direction in which the wire with the flat cross section is likely to be bent.
Description
[0001] The patent application of the present invention is a divisional application of the patent application for invention with the filing date of August 3, 2009, the application number of 201410106422.7, and the invention title of "blower". technical field [0002] The invention relates to an air blower installed at a high place in a living room. Background technique [0003] Conventionally, for example, in a ventilation fan for a duct, there is known a structure in which a motor and a fan driven by the motor are provided in an outer box that is opened on the lower surface and arranged to be inserted into an installation opening of the ceiling, and is surrounded by a In this fan mode, a fan cover made of plastic is provided. In this structure, an electrical component housing portion having an opening on the lower surface is integrally formed on the outer peripheral portion of the fan cover, and a housing for connecting the leads of the motor and the The connecting terminal ...
