Description

  The present invention relates to a structure for inserting a plug of a vacuum cleaner or the like into an outlet.

  In modern vacuum cleaners, the cord is wound and stored in the vacuum cleaner when not in use, and when the vacuum cleaner is moved during use, it extends according to the moving distance, and is automatically wound when the use is finished. It has come to be taken. In this way, the long code is kept out of the way.

  However, in order to wind up the cord at the end of cleaning, it is necessary to go to the position where the outlet is located and unbend and unplug. Further, when cleaning a wide space by sequentially changing the plugs to different outlets, there is a problem that workability is very bad because the plugs must be removed to the outlet position each time.

Problems to be solved by the invention

  The present invention was carried out so that the plug of a vacuum cleaner or the like could be pulled out without going to the outlet position.

Means for solving the problem

  According to the present invention, in a plug insertion structure into an outlet configured by inserting a plug into an outlet, a plug detaching means for detaching the inserted plug from the outlet based on a command signal given by remote control is provided. It was set as the structure made.

  According to the above configuration, the plug detaching means is actuated by the command signal by remote operation, and the plug is detached from the outlet. The plaque detaching means can be appropriately arranged separately from the plug side, the outlet side, and both. The command signal by remote operation may be given via a cord connected to a plug in addition to being given by radio waves.

The invention's effect

  According to this invention, it becomes possible to remove the plug from the outlet by an operation at the position of the electric device to be used such as a vacuum cleaner, thereby saving the trouble of pulling the plug by bending to the outlet position, The use of electric equipment becomes easy and the workability thereof is improved.

First Embodiment FIG. 1 is a cross-sectional view showing a structure for inserting a plug into an outlet according to the present invention, and FIG. 2 is a perspective view of the plug (when inserted as shown in FIG. 1).

  In this embodiment, the plug detaching means is provided on the plug 1 side, and the outlet 2 is provided on the wall surface 4 and the connection terminal 3 is disposed therein. The plug 1 is configured such that an operating body 6 is provided in an upper part of a casing 5 so as to be slidable in a horizontal direction, and a lock device 7 is provided in a lower part. A pair of connection terminals 8 are embedded in the operating body 6 so that a part thereof protrudes from the front surface of the operating body 6, and the rear end of the connection terminal 8 extends to the inside of a boss 9 protruding from the rear surface of the operating body 6. A cord 10 that is extended and coated on a lead wire connected to the rear end of the cord 10 extends to the outside from an opening 12 formed on the rear surface of the casing 5 and is connected to a device such as a vacuum cleaner.

  A coil spring 14 is externally fitted to the boss 9, and the coil spring 14 is always urged in the contracting direction and its front end is locked to the rear surface of the operating body 6. As shown in FIG. Further, the operating body 6 is provided with pushing pieces 16 projecting on both sides, and each pushing piece 16 is positioned to project outside from a slide opening 17 formed on the side surface of the casing 5. The actuating body 6, the locking device 7, and the coil spring 14 constitute plug detaching means.

  As shown in the circuit diagram of FIG. 4, the locking device 7 operates when the receiving circuit 20, the switch circuit 21 that is turned on when receiving a reception signal from the receiving circuit 20, and the switch circuit is turned on. A solenoid mechanism 22 and a battery battery 23 serving as a power source for operating the solenoid mechanism 22 are provided, and a lock piece 24 interlocking with the solenoid mechanism 22 is located so as to protrude to the outside. The lock piece 24 is normally urged upward by a spring and protrudes to the outside, and is recessed downward in conjunction with the operation of the solenoid mechanism 22. The battery battery 23 has its charging terminal exposed on the lower surface of the locking device 7, and a connecting terminal of a charging rod can be connected to the charging terminal through a charging opening 25 formed on the lower surface of the casing 5.

  The operation of the plug 1 used in connection with a vacuum cleaner will be described below. When the vacuum cleaner is not used and the plug 1 is not connected to the outlet 2, the connection terminal 8 does not protrude from the front surface of the plug 1, as shown in FIG. Accordingly, when connecting, the pushing pieces 16 projecting on both sides are pushed in with the front face of the plug 1 aligned with the predetermined position of the outlet 2, and the operating body 6 is moved forward to bring the connection terminal 8 into the outlet 2. Insert it. The position of the plug 1 on the front surface of the outlet 2 is aligned with the positioning step 27 of the front plate 29 of the outlet 2. Then, the locking piece 24 of the locking device 7 protrudes upward by the spring bias at the position where the connecting terminal 8 is further inserted deeply and is elastically held between the terminals 3 on the outlet 2 side. By locking 24 on the rear surface, the operating body 6 is locked in that position, and the plug 1 shown in FIG. In this state, the vacuum cleaner is used.

  The vacuum cleaner is provided with a remote switch for emitting a command radio signal for detaching the plug to the lock device 7 of the plug 1, and the command radio signal transmitted by the operation of the remote switch when the vacuum cleaner is used is received circuit. When the signal is received at 20, the switch circuit 21 is turned on by the reception detection signal from the receiving circuit 20 and the solenoid mechanism 22 is operated, whereby the lock piece 24 is recessed. When the lock piece 24 is no longer locked, the operating body 6 is pulled backward by the coil spring 14, the connection terminal 8 comes out of the connection terminal 3 of the outlet 2, and the plug 1 is detached from the outlet 2.

  In this way, the user of the cleaner can unplug the plug 1 from the outlet 2 by a switch operation at a position where the cleaner is located without going to the outlet 2 position and without bending at the outlet 2 position. The remote switch on the cleaner side does not necessarily have to be fixed to the cleaner, and may be configured to be detachable and shared with other electric devices.

  As a modification of this embodiment, there is one in which the lock mechanism 7 of the plug 1 is provided on the side of the operating body 6 and the lock piece 24 is engaged with the casing 5 side of the plug. The mechanism 22 can be configured to take power from the outlet 2 side.

Second Embodiment FIG. 5 is a cross-sectional view showing a structure for inserting a plug into an outlet according to the present invention, and FIG. 2 is a perspective view of the outlet.

  In this embodiment, the plug detaching means is provided on the outlet 30 side, and a conventional plug 31 is used. The outlet 31 is embedded in a wall surface 34, a connection terminal 33 and a plug detaching device 35 as plug detaching means are provided in the base body 32, and the front surface thereof is covered with a cover 36. A detaching lever 37 interlocking with an internal solenoid mechanism extends from the plug detaching device 35, and a front portion 38 of the detaching lever 37 is disposed at a position between the pair of plug insertion holes 40 on the front surface of the cover 36. Yes. Power to the solenoid mechanism is supplied from the outlet side.

  With such a configuration, when a command radio signal of a paradox is given from the cleaner side to the plug detaching device 35 as in the first embodiment, the detaching lever 37 is operated by operating the internal solenoid mechanism. The plug 31 is released by being pushed forward and pushed by the front portion 38 of the release lever 37. In this way, the same effects as those of the first embodiment are exhibited.
