[0002]

2. Description of the Related Art The applicant of the present invention has disclosed a Japanese Patent Application No. Hei 2-84747 as a mat vacuum cleaner which vibrates a carpet-like mat which is laid in the interior of a car or the like to expel dust which has entered a raised portion of the mat. The vacuum cleaner described in is proposed. The mat vacuum cleaner described here is equipped with a mat holding plate above the air passage plate, supports the mat with one hand when mounting the mat, and pushes the mat holding plate with the other hand against the bias of the spring. The mat was inserted away from the fixed portion, the mat was inserted therebetween, and the mat pressing plate was pressed against the mat to fix and hold the mat.

[0003]

However, the work of manually attaching and detaching the mat has been very troublesome and troublesome. Further, since the mat is mounted while supporting the mat, the mat may be deformed and mounted, and the mat thus mounted cannot obtain a sufficient dust removing effect due to vibration. The present invention has been made to address such a problem, and an object of the present invention is to provide a mat cleaner that can automatically mount a mat.

[0004]

In order to solve the above problems, the present invention provides an air supply means for supplying air, and an air supply means for supplying air supplied from the supply means to an air path plate and a carpet-like mat. A mat that includes: a blowing nozzle that blows out toward the space; fixing means for fixing and holding the mat at a predetermined position facing the air path plate; and operating means operable with the mat introduced to a predetermined position. Is operated to operate the operating means to give an operation to the fixing means to fix and support the mat.

The valve 18 is kept closed by the plate 18.

Reference numeral 29 denotes an operating means for operating the air cylinder 26 as a fixing means. The micro switch 30 is mounted on the back surface of the front plate 3, and both ends are bent in a U-shape toward the center and the ends thereof are formed in the front plate 3. An operating rod 31 rotatably supported on the back side of the lower end of the lever, and a lever 3 fixed to the circumferential surface of the operating rod 31 and pressing a push button of the microswitch 30
The operation rod 31 is disposed at a position where the hand holding the mat M can be hit when the mat M is inserted from the mat insertion slot 13 to the mat fixing position. L-shaped support plate 3 fixed to both sides of the part

FIG. 5 shows an electric circuit diagram of the mat vacuum cleaner.
The motor 9 for driving 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 42. The single-phase power supply is connected to the electromagnetic coil C ₁ of the electromagnetic switch 42, the micro coil 30 of the micro switch 30 and the electromagnetic coil C ₂ of the electromagnetic relay 43, and the normally open contact S _{4 of the} relay 43 via the operation 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 43 in parallel with.

Next, the operation of the thus constructed mat cleaner will be described. First, the operator pushes the operation switch 2 and then opens the door 5 toward the front to move on to 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 and S ₃ are closed, and the blower 10 is driven by the drive of the motor 9 to wait for a switch input from the microswitch 30.

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.

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. The air blown out from the blowing nozzle 7 causes a pressure fluctuation between the mat M and the air path plate 4, and the pressure fluctuation causes the mat M to vibrate at high speed to drive out the dust that has entered the raised portion of the mat M. The dust expelled from the door is guided to the dust receptacle 6 through the back surface of the door 5.

Here, the operator turns the adjusting knob 41 to change the distance between the mat M and the air path plate 4 and moves the vibration starting position of the mat M up and down so that the entire mat can be evenly distributed. Vibration completely removes dust that has entered the raised portion of the mat M.

After 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.
