Abstract

PURPOSE:To prevent dust clogging inside piping by stopping an electric motor after a certain period of time after switching OFF an ON-OFF circuit of the motor through a delay means, and increasing output of the motor within a certain period of time. CONSTITUTION:A floor brush 55 is attached to one end of an extension pipe 54 which is coupled with a tube 51 at the other end. A cleaning hose 5 is inserted into a connection opening 4 of a room to be cleaned. When a hand switch 53 is turned ON, an electric motor 75 of a cleaner body begins to rotate, so that dust one the floor 2 or 3 is sucked through the floor brush 55, then through a piping 6 and finally collected within a dust collecting case 71. When the hand switch 53 is turned OFF at the finish of cleaning, a delay circuit 9 operates to let the electric motor 75 to continue to rotate with the output increased. After that, when a delay time period corresponding to CR value of the delay circuit 9 has passed, a fan 76 stops its operation. Thus the dust sucked by the floor brush 55 just before the turn-OFF of the hand switch 53 is collected within the dust collecting case 71 so completely that any amount of it does not remain with in the piping.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a central cleaner.

[Conventional technology]

The central cleaner is configured to use the main body of a stationary electric vacuum cleaner to intensively collect dust from connection ports provided at multiple locations in each room of a building through walls and pipes under the floor. Dust collection piping depends on the size of the building, but even in a normal house, the length of the piping can be more than 10 meters or even longer. On the other hand, the flow of air that passes through the pipes due to the suction force of the main body of the vacuum cleaner is significantly slower than the rotating and stopping operations of the electric motor, which is controlled by the flow. In contrast, in conventional devices of this type, the delay in air flow as described above is not taken into account.

[Problem to be solved by the invention]

As mentioned above, conventional central cleaners do not take into account the delay in airflow flowing through the pipes. For this reason, when the dirt sucked in from the hose is passing through the pipe.

1! The electric motor in the main body of the dynamic sweeper may stop rotating. If debris gets stuck in the middle of the pipe, it can cause a clog. In particular, if moisture-containing dust or adhesive tape is stopped midway through, it will not only stick to the pipe walls and reduce the dust collection ability, but also block the pipes at 2pm, making it necessary to remove the floorboards and replace the pipes. There were problems such as having to do so.

The present invention was created with attention to the current situation, and was created by providing a delay circuit in the on/off circuit of the machine, and using this circuit, it is possible to wait for a certain period of time after turning off the power switch. '11 since the garbage was completely collected! This is a central cleaner that stops the rotation of the machine.

[Means to solve the problem]

A delay circuit is provided in the on/off circuit of the dust collecting motor of the main body of the present invention, and the rotation of the motor is stopped after a certain period of time after the on/off circuit of the #t@ machine is turned off. It is a companion device that constitutes a central cleaner that increases the output of the electric motor within a certain period of time.

[Effect]

When you connect the cleaning hose to the connection port and turn on the switch, the electric motor for dust collection rotates and dirt on the floor is sucked into the hose. The dust that is sucked in is sent to the suction port of the main unit through piping.

The dust is collected in the dust collection case. Even after cleaning is finished and the switch is turned off, a delay circuit operates and the dust collection motor continues to rotate for a while with increased output.

The delay time of the delay circuit is set corresponding to the length of the piping. After a certain period of time has passed and all the dust sucked in from the hose has been collected into the dust collection case, the dust collection electric motor stops rotating.

Further, the delay circuit (9) is constituted by an OR circuit consisting of two resistors and a capacitor, for example, and the capacitance of the capacitor at each connection port (4) is selected to correspond to the length of the pipe f61. Furthermore, when this delay circuit (9) is in operation, 11t@

When you finish cleaning the club room and turn off the hand switch (53),
The delay circuit (9) operates and the electric motor (75) increases its output and continues to rotate. Then, after the delay time corresponding to the OR value of the delay circuit (9) has passed.

The rotation of the fan (76) caused by the electric motor (75) K stops. In this case, the dust sucked in from the floor brush (55) just before the first hand switch (53) is turned off is collected into the dust collection case (71) using the delay time and left in the middle of the pipe (6). There is no chance that I will be disappointed. Moreover, the electric motor (75

When the rotation of 75) has stopped, the cleaning hose (5) can be pulled out from the connection port 14) and inserted into the concubine connection port 14) of the primary room, and cleaning can be performed in the same manner.

In addition, although the above-mentioned example illustrated and explained the case of a two-story general house, it may also be a building such as a Chichisuji building or an office. Further, although the explanation has been given with respect to the case where the electric vacuum cleaner is installed outside a building, it goes without saying that the present invention can also be applied when the electric vacuum cleaner is installed inside a building.

〔Effect of the invention〕

As described above, the present invention is a central cleaner for character collection in which a delay means is provided in the on/off path of the motive. As a result, when the on/off circuit of the motor is turned off by operating the hand switch, the rotation of the motor will stop after a certain period of time has elapsed due to the delay means. The motor's output has been improved to powerfully move debris inside the pipes.

Therefore, all the dirt sucked in by the unbrushed end of the cleaning hose and noise is collected into the Togaku case, and no dirt gets stuck in the middle of the pipe.

Therefore, according to the present invention, there is provided a central cleaner which has various features such as being able to prevent the occurrence of garbage in pipes with a simple configuration, being free from malfunctions, and requiring no installation or replacement work. can be realized.
