Description of the Related Art For example, in a vacuum cleaner using a paper bag filter disclosed in Japanese Utility Model Application Laid-Open No. 59-139257, when the base of the paper bag filter is correctly set in a dust suction port of a dust collecting case, pressing is performed. A possible pin is pushed in by the backing and the lid of the dust collecting case is closed. That is, a mechanism is provided that does not close the lid if the user forgets to attach the paper bag filter to the dust collection case. [0003] However, in the case of using a paper mount, the mount may be damaged or the pin portion may not be pressed properly due to deformation or the like, and the lid may not be closed properly. In addition, there is a disadvantage that the seal with the dust suction port is deteriorated due to breakage or deformation of the backing paper. SUMMARY OF THE INVENTION [0004] The present invention has been made in view of the above-mentioned drawbacks, and has an electric configuration capable of preventing a paper bag filter from being forgotten by a simple configuration and preventing breakage or deformation of a mount. It is an object to provide a vacuum cleaner. [0005] The first means of the present invention is:
A cleaner body having a dust collecting chamber, a lid for opening and closing the opening of the dust collecting chamber, a paper bag filter provided with a mount having an intake port, and a communication port; A plate-shaped holder for fixing the suction port in a state of communicating with the communication port, and the dust collecting chamber for supporting the plate-shaped holder supporting the mount at a position where the suction port of the mount opposes the dust suction port of the dust collection chamber. A support portion formed on the plate-shaped holder, and in a state where the mount is mounted on the plate-shaped holder, one end of one of the plate-shaped holder and the mount is projected outward from the other one end, and the plate is The other of the shape holder and the backing sheet, at least a part of the other side end opposite to the one side end is made to protrude outward from the one other side end, and is brought into contact with a stopper formed on the lid. A position where the lid is prevented from engaging with the dust collecting chamber, and a stopper for the lid. And a blocking member which is retracted from a position where the cover comes into contact with the cover and moves between a position where the lid and the dust collecting chamber can be engaged, and urges the blocking member to a position where the blocking member comes into contact with a stopper of the cover. An urging means is provided, and the blocking member comprises:
It is characterized in that the plate-like holder and the backing sheet are retracted against the biasing force of the biasing means by abutting in the width direction on the other side end protruding from the one other side end. A second means of the present invention comprises a cleaner body having a dust collecting chamber, a lid for opening and closing the opening of the dust collecting chamber, and a paper bag filter provided with a mount having an air inlet.
A plate-shaped holder having a communication port, and fixing the backing sheet in a state where the suction port of the backing sheet communicates with the communication port; and a plate-shaped holder supporting the mounting sheet, the suction port of the backing sheet serving as a dust suction port of the dust collection chamber. A support portion formed in the dust collecting chamber so as to be supported at an opposing position, and in a state in which the mount is mounted on the plate-shaped holder, one end of the plate-shaped holder is moved outward from one end of the mount. At the other end opposite to the one side end, at least a part of the mount is projected outside the other end of the plate-shaped holder, and abuts a stopper formed on the lid. A position for preventing engagement between the lid and the dust collection chamber,
A blocking member is provided that retreats from a position where the lid comes into contact with the stopper and moves between a position where the lid and the dust collecting chamber can engage with each other, and moves the blocking member to a position where the blocking member comes into contact with the stopper of the lid. An urging means for urging is provided, and the blocking member retreats against the urging force of the urging means by abutting in the width direction on the other end of the mount protruding from the other end of the plate-shaped holder. The configuration is characterized. According to the above construction, when the mount of the paper bag filter is set on the plate-shaped holder and mounted on the dust suction port of the dust collecting chamber, the blocking member comes into contact with the mount and comes into contact with the stopper of the lid. Withdrawing from the position, the dust collecting chamber can be closed by the lid. [0008] Since the blocking member is configured to abut on one side end of the backing paper of the paper bag filter and retract, if the user forgets to attach the paper bag filter, the blocking member does not retract and the blocking member is attached to the lid. The blockage of the dust collection chamber by the lid is prevented by contacting the stopper. In addition, since the side end of the plate-shaped holder is formed so as to protrude outward from the side end of the backing sheet at the other side end opposite to the one side end with which the blocking member abuts, forgetting to attach the plate-shaped holder, the paper bag When only the filter is installed, the paper bag filter is pushed by the blocking member and moves, so the blocking member does not retreat and the blocking member contacts the stopper on the lid to prevent the lid from blocking the dust collection chamber. Is done. An embodiment of the present invention will be described below in detail with reference to the drawings. 1 is a floor suction port, 2 is a vacuum cleaner main body, 3 is a handle pipe having a handle 4, and these are connected linearly to form a vertical vacuum cleaner.
