Is changed in the vertical direction.

FIG. 4 shows an electric circuit diagram of the mat vacuum cleaner.
The motor 9 that drives the blower 10 is connected to a three-phase power supply via normally open contacts S ₁ , S ₂ , and S ₃ of the electromagnetic switch 43. Further, normally open contact S ₄ and the electromagnetic solenoid coil C _2, and the relay 43 of the electromagnetic coil C _1, and the micro switch 30 and the electromagnetic relay 44 of the electromagnetic switch 43 in the single-phase power supply via the operating switch 2 connect the circuit connected in parallel to the electromagnetic coil C ₃ of the valve 27, further microswitch 30
Connecting the normally open contacts S ₅ of the electromagnetic relay 44 in parallel with.

Next, the operation of the thus constructed mat cleaner will be described. First, the operator presses the operation switch 2 and then pulls out the dust catcher 5 to move the work of mounting the mat M. On the other hand, the electric circuit energizes the electromagnetic coil C ₁ by pressing the operation switch 2 and the normally open contact S _1. , S
_2, the closed S _3, the switch waits for input from the microswitch 30 by the blower 10 into the operating state by the driving of the motor 9.

When the blower 10 is driven, most of the air supplied from the blower 10 is blown out into the main body 1 through the opening 19, and the amount of air blown out from the blow-out nozzle 7 is reduced. When the mat M is inserted from the mat insertion opening 13, the mat M can be easily inserted without receiving wind pressure resistance. In addition, in the standby state, the tip of the adjustment plate 35 is in contact with the air path plate 4, so that the air blown out from the outlet 8 spreads in the left-right direction, and vibrates the mat at the time of mounting the mat M to generate dust. To prevent splashing.

Here, the operator holds the upper end of the mat M with both hands, inserts the upper end of the mat M through the mat insertion slot 13, and when the mat M is inserted to a predetermined position, the hand holding the mat M is operated. Lift the rod 30 and wait for the mat M to be fixed. The hand holding the mat hits the operating rod 31 before entering the danger zone above the mat insertion slot 13 and does not accidentally get caught in the mat holding plate 12 and cause an accident. On the other hand, when the microswitch 30 is closed, the electric circuit energizes the electromagnetic coil C ₂ to close the normally open contacts S ₄ and S ₅ , to maintain the energized state of the electromagnetic coil C ₂ , and the electromagnetic coil C _{3 of the} electromagnetic valve 27. To supply compressed air to the air cylinder 26 to extend the lot of the air cylinder 26.

When the air cylinder 26 is extended, the mat pressing plate 12 presses the mat M against the front surface of the blowing nozzle 7 and the air passage plate 4 to fix and hold the mat M, and to open and close the on-off valve 1.
8 is turned to a closed state, and air is blown out from the blowing nozzle 7 toward between the mat M and the air path plate 4. Here, the operator turns the adjustment knob 41 to change the distance between the mat M and the air passage plate 4, and determines the distance between the mat M and the air passage plate 4 based on the thickness h _{0 of the} outlet 8. If set to a short distance h ₁ (FIG. 5
(Refer to (1)), the air blown out from between the tip of the adjusting plate 35 and the air path plate 4 accelerates the wind speed and starts vibration having a smaller amplitude than the point a, and the distance between the mat M and the air path plate 4 Is set to a distance h ₂ equal to the thickness h ₀ of the outlet 8 (FIG. 5).
(See (2)), the mat M swells from the tip of the adjustment plate 35 to a point above the point b, and the maximum wind speed is reached at the point b approaching the air path plate 4 due to the weight of the mat M. When the high-speed vibration is started from the point b and the distance between the mat M and the air path plate 4 is set to a distance h ₁ longer than the thickness h ₀ of the outlet 8 (see FIG. 5C), the adjusting plate C from the tip of 35
The mat M swells to a point above and the maximum wind speed is reached at the point c where the mat M approaches the air path plate 4 due to its own weight.
Thus, by changing the adjusting means 34, the mat M
The vibration starting point moves in the vertical direction, and the entire mat is vibrated evenly to completely expel dust that has entered the raised portion of the mat M and guide the dust expelled from the mat M to the dust receiver 5.

When the cleaning of the mat M is completed, the operator presses the operation switch 2 and waits for the mat M to be released from the fixed state, while the electric circuit turns off the electromagnetic coil C ₁ when the operation switch 2 is opened. Switch to energized state and open normally contact S
₁ , S ₂ and S ₃ are opened, and the blower 1
0 is stopped. Also, the closed state of the on-off valve 18 with the electromagnetic coil C ₃ of the solenoid valve 27 shuts off the supply of compressed air to the air cylinder 26 in turn de-energized state, to release the mat pressing state of the mat pressing plate 12 Has been released.
