In addition, a packing is provided at the connection portion of each component to maintain airtightness during operation. Further, a structure for positioning the dust collector 2 and the dust collector 2 are fixed to the cleaner body 1 so that the dust collector 2 can be easily kept airtight when attached to the cleaner body 1. The structure for.
(About air flow)
In such a handy type vacuum cleaner 100, air flows as shown by arrows in FIGS. At this time, the solid line arrow represents the flow of the incoming air, and the broken line arrow represents the flow of the air in the exhaust circulation.

  The air containing the dust sucked from the suction port 6 reaches the dust collecting device 2 through the introduction pipe 6c, passes through the dust collecting filter 14 provided in the dust collecting device 2, and reaches the electric blower 5 through the duct 8a. . The air discharged from the electric blower 5 is divided into air discharged from the main body exhaust port 4 and air flowing into the exhaust circulation path 11. The air flowing into the exhaust circulation path 11 is discharged to the suction chamber 6a via the exhaust circulation path 11, and is again sucked from the introduction pipe 6c. The air flowing into the exhaust circulation path 11 is heated by the heat generated from the electric blower 5 when passing through the electric blower 5, and the heated air passes through the exhaust circulation path 11 and the introduction pipe 6c. It circulates again to the dust collector 2. Thereby, the heated air enters the dust collector 2, and the inside of the dust collector 2 can be heated to a temperature at which harmful microorganisms such as mites can be exterminated.

  In the present embodiment, when the exhaust circulation path 11 is arranged inside the cleaner body 1, the exhaust heat from the electric blower 5 is provided outside the cleaner body 1 or outside the cleaner body 1. The structure which conveys to the dust collector 2 with a short flow path is employ | adopted. Further, by forming the exhaust circulation path 11 with an elastic material such as rubber or elastomer, it is possible to flexibly pipe the cleaner body 1 inside, and less space than when the flow path is formed by plastic molding. The flow path can be configured.

  In order to get rid of ticks by increasing the temperature in the dust collector 2, it is necessary to heat the ticks to a temperature of 50 to 60 degrees where the ticks can be extinguished, but the exhaust circulation path passes through the inside of the cleaner body 1. By constructing with a flow path, an exhaust circulation flow path is created with a conventional canister-type hose or extension tube, and the suction port is longer than the type that passes through the vacuum cleaner body 1. It is possible to reduce the fear that the exhaust temperature will be lowered when discharged into the tank.

  Moreover, since it is not necessary to raise the exhaust heat from the electric blower 5 for heating in the dust collector 2 by preventing the exhaust temperature from being lowered, the plastic is dissolved or used due to the exhaust temperature becoming high. Can reduce the risk of burns.

  Inside the vacuum cleaner main body 1, a temperature detection means 16, for example, a thermistor is provided behind the dust collector 2, and it is possible to detect the temperature of the outer shell of the dust collector 2 when heated by exhaust circulation. is there. At this time, the temperature detection means 16 is connected to the control circuit board 10 inside the cleaner body 1.

  If the dust collector 2 exceeds a predetermined temperature by continuing the exhaust circulation, the control board 10 connected to the temperature detection means 16 automatically suppresses the input to the electric blower 5 and reduces the air volume of the exhaust circulation. . By reducing the air volume of the exhaust gas circulation based on the detection result of the temperature detection means 16, the temperature rise in the dust collector 2 can be suppressed.

(About the structure of the dust collector)
Next, the dust collector 2 will be described with reference to FIGS. 4 is a front view of the dust collector 2, FIG. 5 is a cross-sectional view taken along the line AA of the dust collector 2 shown in FIG. 4, and FIG. 6 is a development view of the dust collector 2.

  The dust collector 2 is generally formed of an outer cylinder 12, an inner cylinder 13, a dust collection filter 14, and a filter case 15 that houses the dust collection filter 14. The filter case 15 is provided on the outer cylinder 12, and the outer cylinder An inner cylinder 13 is provided so as to be concentric with 12.

The outer cylinder 12, the inner cylinder 13, and the filter case 15 are formed of a material such as plastic.
(About the outer cylinder)
The outer cylinder 12 has a substantially cylindrical shape with an open top, and has an inlet 12a on the bottom surface. The opening part of the inflow port 12a is substantially square shape. The filter case 15 provided on the upper part of the outer cylinder 12 has a lid structure, and the dust collector 2 is divided into an outer cylinder 12 and a filter case 15.

  In the present embodiment, the case where the outer cylinder 12 is substantially cylindrical has been described as an example. However, the present invention is not limited to this, and the outer wall may be a substantially cylindrical shape because the inner wall may be substantially cylindrical. It may be a shape and can be changed as appropriate.

  The outer cylinder 12 includes a substantially cylindrical swirl chamber 12b that has an inflow port on the bottom surface and communicates with the inner cylinder. The swirl chamber 12b has a spiral structure in the swirl chamber 12b, and can swirl the air flowing in from the inlet 12a and separate dust sucked together with the air by centrifugal force.

  The outer cylinder 12 includes a dust collection chamber 12c formed in a substantially cylindrical shape that communicates with the swirl chamber 12b and accumulates dust. The dust collection chamber 12c accommodates dust separated by centrifugal force in the swirl chamber 12b. When harmful microorganisms such as mites are contained in the dust, they can be eliminated by causing them to collide with the inner walls of the swirl chamber 12b to the dust collection chamber 12c by centrifugal force generated by swirling. Moreover, the dust collection chamber 12c is provided with a collision wall 12d as shown in FIG. 5, and the dust swirling in the dust collection chamber 12c collides with the collision wall 12d, so that mites contained in the dust etc. It is possible to get rid of harmful microorganisms.

  In the present embodiment, the case where the collision wall 12d is provided at one location has been described as an example, but the present invention is not limited to this. Since dust that swirls within the dust collection chamber 12d only needs to collide, the collision walls 12d may be provided at two or more locations, and can be changed as appropriate.

The outer cylinder 12 is made of a transparent plastic having a low heat transfer coefficient, such as an acrylic resin or PET. Thereby, when the outer cylinder 12 is heated by exhaust gas circulation, the outer cylinder 12 can be maintained in a high temperature state, and therefore dust containing harmful microorganisms such as mites accommodated in the dust collecting chamber 12c is contained. It is possible to sufficiently heat the dust. In the present embodiment, the case where the outer cylinder 12 is made of a material having a small heat transfer coefficient has been described as an example. However, the present invention is not limited to this. Since it is only necessary to maintain the temperature at which the outer cylinder 12 is heated by exhaust gas circulation, a shape that does not release heat to the outside by using a double wall as the outer cylinder may be used and can be changed as appropriate.

(About the inner cylinder)
The inner cylinder 13 has a cylindrical shape with an opening in the upper direction, and a shape in which a lower portion is reduced to a taper shape from a certain portion. The taper shape surface of the present embodiment is perpendicular to the central axis. In this state, it is inclined about 13 degrees from the horizontal plane. The taper-shaped surface has a plurality of holes communicating with the swirl chamber 12b, and air separated from dust in the swirl chamber 12b flows into the inner cylinder 13. At this time, by making the lower part into a taper shape, the surface area of the taper-shaped surface is enlarged, and air can easily flow into the inner cylinder 13.

The inner cylinder 13 communicates with the dust collection filter 14 and allows air passing through the inner cylinder 13 to flow into the dust collection filter 14.
(Dust collection filter and filter case)
The dust collecting filter 14 is housed in a filter case 15 provided on the outer cylinder 12.

  The dust collection filter 14 is provided with a pleated air filter or the like, and can filter the air passing through the inner cylinder by the air filter.

The filter case 15 includes an exhaust port 15a that communicates with the inner cylinder 13 and communicates with the duct 8a. Air that has passed through the dust collection filter 14 can flow into the duct 8a.
(Air flow in the dust collector)
By providing the vacuum cleaner main body 1 with the dust collector 2 having the above structure, the air containing the dust flows as follows. The flow in the dust collector 2 during the operation of the cleaner will be described with the arrows shown in FIG. At this time, the solid line arrow represents the air flow, and the alternate long and short dash line arrow represents the dust flow.

  When the user starts operation with the operation button 7 provided on the hand handle 3, the electric blower 5 rotates and sucks air. The sucked air flows into the swirl chamber 12b in the dust collector 2 from the inlet 12a on the bottom surface of the outer cylinder 12 through the suction chamber 6a and the introduction pipe 6c. The air that has passed through the swirl chamber 12b becomes a swirl flow, centrifugal force acts on the dust, and the dust and air are separated.

  At this time, when harmful microorganisms such as ticks are contained in the swirled dust, the harmful microorganisms such as ticks are extinguished by collision with the inner wall of the outer cylinder 12 of the dust collector 2 during turning.

In addition, much of the air separated from the dust flows into the inner cylinder 13. Then, the air passes through the dust collection filter 14 and reaches the duct 8a through the discharge port 15a of the filter case 15. The air is heated from the electric blower 5 and is circulated to the dust collector 2 through the exhaust circulation path 11, and the inside of the dust collector 2 is heated to a temperature at which harmful microorganisms such as mites can be exterminated. It is possible to get rid of harmful microorganisms such as ticks that couldn't be eliminated due to the collision of time.
