As shown in FIG. 2, each of the exhaust port 10 and the exhaust intake port 11 has an opening portion 12. The opening portion 12 is opened and closed by rotating a valve 13 having a screw portion 13a at the bottom. By. The valve 13 has a groove 13b formed to fit the shape of the hose so that the intake hose 5 or the exhaust hose can be fitted into the valve 13. By pressing 14 to the opening 12,
This is a packing that keeps the opening airtight. Reference numeral 15 is a guard 15 for preventing the futon 9 from blocking the opening 12.

In FIG. 2, the opening 12 of the discharge port 10 is opened, and the groove 13 of the valve 13 of the discharge port 10 is opened.
The state where the intake hose 5 is fitted in b is shown, and when the electric vacuum cleaner 1 operates in this state, the air in the storage bag 8 is sucked by the electric vacuum cleaner 1 as shown by the arrow. On the other hand, the opening 12 of the exhaust intake 11 is closed, and the exhaust intake 11 is provided with a lid 16 for preventing the opening 12 from being clogged with dust or the like.

In FIG. 1, 17 is an electric blower 6
It is an exhaust hose for exhausting the exhaust air from the storage bag 8 and one end of which is fitted into the exhaust port 7. Numeral 18 is a temperature fuse switch for automatically stopping the electric blower 6 in order to prevent the electric blower 6 from overheating when it detects that the temperature inside the storage bag 8 has exceeded the death temperature of ticks. It is provided in the vicinity of the end of one end that is fitted to the main body 2.

Next, the tick removing operation of the thus constructed vacuum cleaner exhaust heat circulation device will be described.

First, the end of the suction hose 5 on the side where the temperature fuse switch 18 is provided is fitted into the suction port 4 of the vacuum cleaner body 2, and the exhaust hose 17 is connected to the exhaust port 7.
Insert one end of. At this time, the thermal fuse switch 18 is connected to a power supply circuit (not shown) of the main body 2.

Next, the opening 12 of the discharge port 10 of the storage bag 8
Is opened by the valve 13, and the other end of the intake hose 5 is fitted into the groove 13b of the valve 13. Also,
Similarly, after the opening 12 of the exhaust inlet 11 of the storage bag 8 is opened by the valve 13, the other end of the exhaust hose 17 is fitted into the groove 13b of the valve 13.

Thereafter, when a power switch (not shown) of the main body 2 is turned on and the electric blower 6 in the main body 2 is rotated, the exhaust air from the electric blower 6 is exhausted through the exhaust port 7, the exhaust hose 17 and the storage bag 8. After passing through 11, the air is exhausted into the storage bag 8 as shown by the arrow A, and the heat of the exhaust is gradually transferred to the futon 9.

On the other hand, the air in the storage bag 8 is sucked into the main body 2 from the intake port 4 of the main body 2 through the outlet 10 of the storage bag 8 and the intake hose 5 as shown by the arrow B. In this way, the exhaust gas circulates between the vacuum cleaner 1 and the storage bag 8.

Then, as the winding temperature of a motor (not shown) in the electric blower 6 rises, and the exhaust gas temperature rises accordingly, the exhaust gas discharged into the storage bag 8 becomes hot, and the hot air exhausts the futon 9 The temperature rises.

Eventually, when the temperature of the exhaust gas reaches the mite killing temperature, usually about 50 degrees, all the mite on the futon 9 will die. After that, when the temperature of the exhaust gas exceeds the temperature at which the ticks die, the temperature fuse switch 18 is activated, and the electric blower 6 is automatically stopped to prevent overheating. In addition, although mite may be contained in the air sucked from the storage bag 8, the mite is collected in the dust collection chamber 3 and is killed in the dust collection chamber 3 by high temperature exhaust.

After the temperature of the exhaust gas exceeds the mite death temperature and the electric blower 6 automatically stops, the exhaust hose 17 and the intake hose 5 are removed from the storage bag 8, and the valve 13 is turned to close the opening 12. Then, the lid 16 is put on.

By the way, when the power switch is turned on again while the intake hose 5 is still inserted into the exhaust port 10 only by disconnecting the exhaust hose 17 and closing the exhaust intake port 11, the electric blower 6 is rotated again. The air in the storage bag 8 is sucked into the main body 2 through the outlet 10 and the intake hose 5. As a result, the inside of the storage bag 8 becomes almost vacuum, and the futon 9 is compressed.

As described above, if the exhaust inlet 11 of the storage bag 8 is closed and the air in the storage bag 8 is sucked out from the discharge port 10, the storage bag 8 can be used as a futon compression storage bag. it can.

Although the thermal fuse switch is provided near the end of the intake hose in the above description, it may be provided on the exhaust hose side if it can be connected to the power supply circuit. In addition, in order to effectively perform futon compression, the operating temperature of the thermal fuse switch may be set higher than the mite killing temperature, if necessary.

By the way, in the above description, the case where the temperature fuse switch is used in order to prevent overheating of the electric blower when the mites are removed and the futon is compressed, the air outside the machine is taken in to drive the electric blower. It is conceivable to cool the fan motor.

Next, another embodiment of the present invention for cooling the motor of the electric blower by such outside air will be described with reference to the drawings.
