Abstract

PURPOSE:To surely exterminate harmful microorganisms by means of a vacuum cleaner main body only by providing a shielding plate which opens or closes the outlet of a circulated passage by utilizing the closed or opened state of the intake port section of a dust collecting chamber to a shutter plate provided at the intake port. CONSTITUTION:The cap-body side passage tube 42 of a circulating passage is composed of 8 lower frame body 44 formed on the side face of a holding frame cover 27 in a united state and an upper frame body 45, and the upper intake tube 46 of the cover 27 is provided with a circulating outlet 47. A notched section 48 is formed at the part of the frame body 45 facing the outlet 47. A shielding plate 49 formed on a shutter plate 29 in a united condition, opens or closes the output 47 when it fits in or out of the notched section 48 as the plate 29 slides, in such a way that the plate 49 closes the outlet 47 when the plate 29 opens an intake port 24, and vice versa. When this cleaner is operated for exterminating such harmful microorganisms as ticks, etc., after cleaning is completed, the output 47 is opened as the plate 49 comes out of the notched section 48 in an interlocked state with the closure of the shutter plate 29 and the exhaust air flow of a motor operated flower 8 is sucked into a dust collecting chamber 4 through the circulating passage 41 and kills the harmful microorganisms such as ticks retained on the surface of a paper bag filter 15.

Description

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

(Explanation) Conventional technology A vacuum cleaner that heats the inside of the dust collection chamber by circulating the exhaust flow of a wind fan into the dust collection chamber after dust and dirt are trapped in the dust collection chamber by cleaning the room was developed in Japanese Patent Laid-Open No. 62 -12 By connecting the outflow rli, a suction hose forms a circulation path for circulating the exhaust flow of the electric blower into the dust collection chamber, and the exhaust flow circulates through the long suction hose, so it is possible to create a circulation path inside the dust collection chamber. This has the disadvantage that heating efficiency deteriorates and the suction hose deteriorates due to heat.

(c) Problems that Fan Ming attempts to solve The present invention circulates the exhaust flow of an electric blower to the dust collection chamber within the vacuum cleaner body, thereby killing and exterminating dust mites and other microorganisms using only the vacuum cleaner body. At the same time, it is an object of the present invention to obtain an electric {1δ remover that completely prevents the circulation of the exhaust gas flow within the cleaner body during the cleaner operating state so that the suction function does not deteriorate.

(2) Means for Solving the Problems The first vacuum cleaner of the present invention has a dust collection chamber with a suction section that can be opened and closed by a shutter plate, and a suction side in the dust collection chamber. The connected electric blower, + 1 of the suction 1-1 part
When the shutter is temporarily closed, the exhaust flow of the electric blower is circulated to the dust collection chamber through the inlet part (n)1, and the ring passage is connected to the dust collection chamber. ：Provided, iii. The shutter/tar plate is provided with a valve that closes the circulation outlet of the circulation passage when the suction section is opened.
It is characterized by having a shielding plate that opens the circulating output ``-1'' in section 61j when the section is closed.

(e) Effect I According to the configuration described in section 2, in the return operation state, as the suction port is opened by the shunter plate, the shielding plate closes the circulation outlet, so the exhaust flow of the electric blower does not enter the circulation passage.
Therefore, the circulation of the exhaust air flow is completely blocked and it does not enter the dust collection chamber, and the suction function from the 11 room is maintained at a high level without degrading. When the captured written microorganisms are exterminated, the shutter plate closes the 11 & 1-1 section and the shield plate opens the circulation outlet ['', so the exhaust flow of the electric blower is sucked and collected through the circulation passage. The dust is circulated from part 1 to the dust collection chamber, and the dust collection chamber is heated to a temperature that can kill objects, thereby killing harmful microorganisms.
