Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a vacuum cleaner that uses hot air to kill pests such as mites sucked into a collection chamber.

(B) Conventional technology Pests such as mites that are inhaled with dust when cleaning a room are usually filtered out by a filter in the dust collection chamber and are not discharged outside the vacuum cleaner, but they breed inside the dust collection chamber. To prevent this, it is necessary to kill and completely exterminate them.

It is known that pests such as mites are killed by applying hot air at about 50 DEG C., and to achieve this, a vacuum cleaner as shown in FIG. 9 is known. That is, in the vacuum cleaner shown in FIG. 9, the tip of the suction hose (51) inserted into the suction port of the main body case (50) is connected to the exhaust outlet (53) of the electric blower II (52) of the main body case (50).
The hot exhaust flow of the electric blower (52) is circulated through the suction hose (51) to the dust collection case (54) to kill pests such as mites in the dust collection case (54). It has become.

However, according to this prior art, the main body case (50)
An exhaust outlet (53) that also serves as a connection to the suction case (51) is required on the exhaust side of the vacuum cleaner, which results in concentrated exhaust when using a vacuum cleaner, making the exhaust noise louder, and furthermore, it takes a long time to exterminate pests such as mites. It takes time to set the suction hose (51), and the suction hose (51) attached to the outside of the main case (50) is bent or sagging, making the main case (50) unstable. Furthermore, since the exhaust flow is circulated through the long suction hose (51), there are drawbacks such as the heating efficiency of the dust collection case (54) becoming poor and the heating time becoming longer.

On the other hand, the suction port of modern vacuum cleaners has a floor suction Some are equipped with a power supply terminal for the motor that rotates the rotating brush.

(C) Problems to be Solved by the Invention The present invention allows hot air to be blown into the vacuum cleaner body to remove pests such as mites by simply attaching a simple attachment to the suction port. The object of the present invention is to provide a vacuum cleaner that can kill insects efficiently and reliably in a short period of time and completely exterminate them.

(d) Means for Solving the Problems As shown in FIGS. 1 to 8, the vacuum cleaner of the present invention has a dust collection chamber equipped with a suction port and houses an electric blower. a vacuum cleaner body, and a hot air blowing unit that is removably attached to the suction port group and blows hot air into the dust collection chamber, and the blowing unit includes a heater electrically connected to the vacuum cleaner body; It is characterized by having a temperature sensing switch that turns off the heater when it is heated by the hot air emitted from the heater and reaches a set temperature.

(e) Effect With the above configuration, during cleaning, dust and pests such as mites are sucked into the dust collection chamber from the suction bow connected to the suction port and stored therein.

After cleaning is completed, attach a hot air blowing unit to the suction port instead of the suction hose, turn on the temperature sensor switch, the heater generates heat, and the electric blower operates to blow hot air from the hot air blowing unit into the dust collection chamber through the heater. The hot air flows in and heats the inside of the dust collection chamber to 50°C or higher, which is the temperature at which pests such as mites die, and the temperature sensing switch is heated to 50°C by the hot air.
When the heating reaches the set temperature, which is set at 70° C., for example, the temperature sensing switch is turned off and the heater is turned off, and in this state, pests such as mites are completely exterminated.
