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 dust collection chamber.

(b) Conventional technology Pests such as mites that are inhaled along 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 can breed inside the dust collection chamber. In order 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 approximately 50°C, and in order to achieve this, the 7U
A vacuum cleaner as shown in A is known. Therefore, the seventh
In the vacuum cleaner shown in the figure, the tip of the suction port (51) inserted into the suction port of the main body case (50) is inserted into the main body case (50). Exhaust outlet (5) of blower (52)
3), and circulates the hot exhaust flow of the dynamic air blower (52) to the dust collection case (54) through the suction hose (51) to kill pests such as mites in the dust collection case (54). It is configured to allow

However, according to this prior art, the main body case (50)
An exhaust outlet (53) is required on the exhaust side of the suction case (51), which is also used for connecting and sewing the suction case (51), and when the cleaning machine is used, it becomes a concentrated exhaust, which increases the exhaust noise and also prevents pests such as mites. It takes time to set up a long suction hose (51) when exterminating the main body case (50), and the suction hose (51) attached to the outside of the main body case (50) may bend or hang down, making the main body case (50) unstable. Also, since the exhaust flow is circulated through the long suction hose (51), the dust collection case (54)
) has disadvantages such as poor heating efficiency and longer heating time.

On the other hand, in addition to the remote control terminal that is electrically connected to the hand control section of the suction hose in order to turn off the electric feeder and control the rotation speed, the suction port of modern vacuum cleaners has a Some are equipped with a power supply terminal for the motor that rotates the rotating brush at the suction port.

(c) Problems to be Solved by the Invention The present invention reduces the rotational speed of the electric feeder in the vacuum cleaner body by simply attaching the simple actuator member to the suction port. By blowing hot air into the vacuum cleaner body with the suction power set to low Fahrenheit, the hot air is allowed to flow into the vacuum cleaner body while still being at a high temperature. There is a means to kill insects efficiently and reliably in a short time, to perform complete extermination, to reduce power consumption when exterminating pests such as mites, and to reduce the rotational speed of TM and dynamic blower. The aim is to obtain a vacuum cleaner that is highly reliable and does not break down due to heat or shock.

(d) Means for Solving the Problems As shown in FIGS. 1 to 6, 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 part and blows hot air into the dust collection chamber, and the suction port has a power supply terminal and a power supply terminal for remote control of the electric blower. The mI recording hot air suction unit includes a heater electrically connected to the power supply terminal, and a relay activation terminal in which a resistor for reducing the rotation speed of the electric blower is connected to a normally open contact. It is characterized in that the terminal has a relay drive i1+terminal end- which supplies power from the power supply terminal.

(E) Function With the above configuration, during cleaning, dust and pests such as mites are sucked into the dust collection chamber through the suction hose connected to the suction port and stored therein.

When a hot air blowing unit is attached to the suction port instead of the suction hose after cleaning, the heater is electrically connected to the power supply terminal, and the relay drive contact is electrically connected to the activation terminal, so that power is supplied to the relay.

Therefore, the electric blower operates at a reduced rotational speed due to the resistance, reducing the suction force, and due to this reduced suction force, hot air heated by the heater flows into the dust collection chamber with a small air volume. Pests such as mites are completely exterminated by heating to a temperature of 50°C or higher, which is the temperature at which pests such as mites die. At this time, since the suction power of the electric blower is reduced, the amount of hot air blown out from the hot air blowing unit is reduced, and therefore high temperature hot air can be blown out using a heater with a small heat generating capacity, reducing overall power consumption. . Furthermore, since the relay and resistor are provided in the vacuum cleaner body rather than in the hot air blowing unit, they are not heated by the hot air.

The configuration allows the time to be delayed by a predetermined amount of time (for example, about 1 to 2 minutes), and then the sensing switch (33) is used as a timer.

(G) Effects of the Invention The vacuum cleaner of the present invention is constructed as described above, and in particular, the hot air blowing unit I as an attachment member is equipped with a heater and a relay drive terminal, and the vacuum cleaner body is equipped with a heater and a relay drive terminal. Power is supplied by an actuating terminal read directly from the
- and a resistor for reducing the rotation speed of the electric blower controlled by the relay, so simply attaching the unit to the suction port of the vacuum cleaner body will reduce the rotation speed of the electric blower. Since the suction force is small and the amount of hot air heated by the heater is reduced, high-temperature hot air can flow into the dust collection chamber using a heater with a small heat generation capacity, and it can easily remove pests such as mites stored in the dust collection chamber. It can be easily exterminated.

Furthermore, since the relay and resistor are placed inside the vacuum cleaner body, these parts are not heated by hot air, nor are they subject to large shocks due to drops, etc., so there is no failure due to such heating or shocks. Furthermore, since the heat source only needs to have a small heat generating capacity and the rotational speed of the electric blower is reduced, the overall power consumption is small and does not exceed the capacity of a household electrical outlet, and the rotation of the electric blower is also reduced. Since the noise is also reduced, the operating noise during extermination of pests such as mites becomes quieter, and it is possible to obtain a highly reliable vacuum cleaner that is difficult to break down and can exterminate pests such as mites anywhere.
