Abstract

PURPOSE:To provide the vacuum cleaner of high economical property with safety by inserting the thermo-protector of an automatic replacer type into a line for connecting a distribution means for feeding power to a floor nozzle motor for driving a rotary brush, and a blower motor to each other. CONSTITUTION:Power is fed to a blower motor 3 and a floor nozzle motor 8 respectively in parallel with each other, from a distribution means 10, and into a line for connecting the blower motor 3 and a distribution means 9 to each other, the thermo-protector 14 of an automatic replacer type is inserted. When a cleaner is worked in said composition, and a dust collecting chamber 4 is filled up with dust, and a hose 5 and an extension pipe 6 are choked with the dust, then air cannot be exhausted, and the blower motor 3 is heated. In this case, before an abnormal temperature is generated by heating, the thermo- protector 14 is turned OFF, and the blower motor 3 is set in a stopped state. When the floor nozzle motor 8 is, moved, then the blower motor 3 is stopped, and thus a user can know with naked eyes that the abnormal temperature is generated, and so a main switch 11 and a floor nozzle switch 12 are tuned OFF, and the blower motor 3 and the floor nozzle motor 8 can be set to a stopped state.

A floor nozzle 7 connected to the main body 1 through a hose 5 and an extension tube 6 is provided with a floor nozzle motor 8 for driving this rotating brush 9. Electric power is supplied to the blower motor 3 and the floor nozzle motor 8 in parallel through a power distribution means 1o, and a main switch 11 and a floor nozzle switch 12 are provided in each power supply circuit. An automatic return type thermoprotector 14 is inserted in the line between the electricity distribution means 1o and the power source 13. The thermo-blot cover 14 is attached near the blower motor 3 so as to operate by sensing the heat of the blower motor 3.

In the above configuration, if the dust collection chamber 4 is full of dust or the hose 5
If the extension pipe 6 is blocked by dust, exhaust cannot be carried out, the blower motor 3 is heated, and the thermo protector 14 is turned off before the temperature reaches an abnormal temperature, and the blower motor 3 and floor nozzle motor 8 are stopped. . Therefore, the user shuts off the main switch 11 and the floor nozzle switch 12 to prevent the blower motor 3 and the floor nozzle motor 8 from restarting.

Problems to be Solved by the Invention In such a conventional vacuum cleaner, the thermo protector 14 is placed in the line between the power source 13 and the power distribution means 10, so if the temperature becomes abnormal, the protector 14 is turned off.
If the user does not notice the abnormality and does not shut off the main switch 11 and floor nozzle switch 12,
After a while, the temperature of the thermo protector 14 became low (when the thermo protector 14 became ON, the blower motor 3 and the floor nozzle motor 8 started suddenly, which was extremely dangerous. Therefore, the thermo protector 14 was changed to a manual reset type). It is possible to do so, but it would be expensive (and impractical).

To explain the operation in the above configuration, when the dust collection chamber 4 is filled with dust or the port 5 or the extension pipe 6 is blocked by dust,
The blower motor 3 is heated when exhaustion is no longer possible, and the thermo protector 13 is turned off before the temperature reaches an abnormal temperature, and the blower motor 3 is brought to a stopped state. Since the blower motor 3 stops while the floor nozzle motor 8 is running, the user can visually tell that the temperature has become abnormal, and turns off the main switch 11 and the floor nozzle switch 12, turning off the blower motor 3 and the floor nozzle motor 3. The nozzle motor 8 can be kept in a stopped state.
