Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a vacuum cleaner designed to kill harmful microorganisms such as mites trapped in a dust collection chamber.

(b) Conventional technology Harmful microorganisms such as mites captured along with dust when cleaning the room, if left untreated, may breed inside the dust collection chamber and escape outside the vacuum cleaner, so to prevent this, they must be killed. It is necessary to eliminate it completely.

Therefore, in Japanese Patent Publication No. 64-7774, the tip of the suction hose connected to the suction port of the dust collection chamber of the vacuum cleaner body was
By connecting to the connection port formed on the exhaust side of the electric blower in the main body, the exhaust flow of the electric blower is circulated through the suction hose to the dust collection chamber, and the temperature inside the dust collection chamber is controlled to prevent harmful microorganisms such as mites. A vacuum cleaner is shown in which harmful microorganisms are killed by heating to a temperature of 50° C. or higher, which is the killing temperature.

However, in the prior art, the long suction hose is also used for circulating the exhaust air, so the suction hose may bend or droop during operation to exterminate microorganisms such as mites, making the vacuum cleaner unstable. In addition, the exhaust flow circulates through a long suction hose, which reduces the heating efficiency of the dust collection chamber and increases the heating time.Also, the temperature difference between the suction port and the connection port increases, causing the inside of the dust collection chamber to deteriorate. If the temperature is maintained at the above-mentioned death temperature, there is a drawback that the temperature on the exhaust side of the electric blower becomes considerably high.

Furthermore, since the connection port is protruded from the rear of the vacuum cleaner body, it is disadvantageous in that it gets in the way during the cleaning operation and is an eyesore.

(c) Problems to be Solved by the Invention The present invention forms an exhaust outlet without protruding from the vacuum cleaner body by using a narrow-mouth suction device stored in the cleaning accessory storage part of the vacuum cleaner body, and By using a simple exhaust circulation pipe body, the dust collection chamber can be heated efficiently, and harmful microorganisms such as mites trapped in the dust collection chamber can be surely killed in a short time. To provide a vacuum cleaner whose circulation pipe body can be used for simple cleaning.

(d) Means for Solving the Problems The vacuum cleaner of the present invention has a built-in electric blower, a dust collection chamber having a suction port on the suction side of the electric blower, and a cleaning small parts storage section. A vacuum cleaner main body having a suction device holding cylinder connected to the exhaust side of the electric blower, and an exhaust circulation having a suction side connecting cylinder connected to the suction port at one end and an exhaust side connecting cylinder at the other end. Consists of a pipe body,
The exhaust side connection tube of the circulation pipe body is removably connected to the narrow-mouth suction device housed in the suction device holding tube.
It is characterized in that it communicates with the exhaust side of the electric blower via the narrow-mouth suction device.

(E) Effect With the above configuration, harmful microorganisms such as dust mites are sucked into the dust collection chamber and captured together with dust during the cleaning operation.

During mite extermination operation after cleaning, connect the suction side connection tube and exhaust side connection tube of the exhaust circulation pipe body to the suction port of the vacuum cleaner body and the narrow-mouth suction device stored in the suction device holding tube, and drive the electric blower. Due to the suction of the electric blower, the exhaust flow from the electric blower enters the exhaust circulation pipe body from the narrow-mouth suction device in the suction device holding cylinder communicating with the exhaust side through the exhaust side connection tube, passes through the circulation pipe body, and is collected. The dust is guided into the dust chamber, further sucked into an electric blower, circulated, heated by the exhaust heat of the electric blower, and heated inside the dust collection chamber until the temperature inside the dust collection chamber reaches 50°C, which is the temperature at which harmful microorganisms such as mites die. Since the above amount is reached, harmful microorganisms such as mites are killed and exterminated.

Further, the mite extermination operation uses the exhaust circulation pipe body and does not use a long suction hose, so the circulation path of the exhaust flow is shortened and the heating efficiency of the dust collection chamber is increased.

Furthermore, by connecting the narrow-mouth suction device to the exhaust side connection tube of the exhaust circulation pipe body, simple cleaning can be performed in place of the suction hose.
