Description

  The present invention relates to a vacuum cleaner.

  In the conventional vacuum cleaner, a dust collection filter is mounted in the dust collection chamber, and the electric blower is operated to collect dust in the dust collection filter. As dust accumulates in the dust collection filter, the dust collection filter gradually begins to clog, and the suction force gradually decreases. At this time, since the pressure inside the dust collecting chamber 202 is larger as the negative pressure than the pressure inside the dust collecting filter, the dust collecting filter sticks to the inner wall of the dust collecting chamber, and the space where the wind flows is reduced and the suction force is reduced. Was the cause of the decline. Therefore, in order to effectively utilize the surface area of the dust collection filter and prevent a reduction in suction force, convex ribs are provided on the inner wall constituting the dust collection chamber to ensure a space for air flow (for example, Patent Document 1). .

  Moreover, since the dust collected on the dust collection filter contains a lot of dirty dust, the suction air that has passed through the dust is unsanitary. Therefore, in order to clean the suction air that has passed through the dust, a vacuum cleaner that has a filter for cleaning the suction air in a space where the suction air flows has been put on the market.

Japanese Patent Publication No. 7-85736 (paragraph numbers 0025 and 0026 and FIG. 7)

  However, in a vacuum cleaner as disclosed in Patent Document 1, in order to effectively utilize the surface area of the dust collection filter and prevent a reduction in suction force, a convex rib is provided on the dust collection chamber wall, However, since the dust collecting filter directly hits the convex rib, there was a risk that the dust collecting filter was damaged and the dust leaked into the dust collecting chamber.

  In addition, a filter is provided substantially above the electric blower in order to clean the suction air that has passed through the dust, but it is unsuitable for actively flowing air through the filter.

  An object of the present invention is to provide an electric vacuum cleaner that solves the above-described problems, prevents a decrease in suction force, and enables air to actively flow through a filter.

  In order to achieve the above object, the present invention is characterized in that a dust collection chamber having an open top surface and a vacuum cleaner body incorporating an electric blower, a dust collection filter mounted in the dust collection chamber, and the dust collection chamber. A lid that covers the upper surface opening of the dust chamber, a filter provided on the dust collection chamber side of the lid, and a holding member that is provided on the dust collection chamber side of the lid and holds the filter, The holding member has a filter storage portion for storing the filter and a flow path space provided on the outer periphery of the filter storage portion.

  In addition, a feature of the present invention is that the dust collection filter includes a mouth plate and a bag member attached to the mouth plate, and the mouth plate is closer to the electric blower than the inlet of the flow path space. It is in that.

  Further, the present invention is characterized in that the length of the flow path space is made longer than the filter housing portion in the direction in which the wind flows.

  In addition, a feature of the present invention resides in that a plurality of exhaust ports of the channel space through which suction air is discharged from the channel space are provided.

  Further, the present invention is characterized in that the lid body is formed of a substantially transparent material, an opaque member is provided outside the lid body, and the opaque member is shaped along the flow path space. .

  According to the present invention, by providing the flow path space on the outer periphery of the filter housing portion, it is possible to prevent the dust collecting filter from being damaged and to prevent the suction force from being lowered.

  In addition, the dust collection filter mouth plate is provided closer to the electric blower than the inlet of the flow path space, and the length of the flow path space is longer than the filter housing portion in the direction of the air flow. Since the filter does not block the inlet of the flow path space, it is possible to prevent the suction force from being lowered and to allow air to actively flow through the filter.

  Further, by providing a plurality of exhaust ports through which the suction air is discharged from the flow path space, it is possible to prevent the suction force from being lowered and to allow the air to actively flow through the filter without relatively reducing the volume of the dust collection chamber.

  In addition, the lid is molded with a substantially transparent material, and an opaque member having a shape along the flow path space is provided outside the lid, so that the appearance is not impaired and the suction force is prevented from being lowered and positively Since the filter can be blown and the outside of the filter housing is not covered with an opaque member, the filter is exposed to external light such as ultraviolet rays. Can be used effectively.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 3 is an overall external view of a vacuum cleaner according to an example of the embodiment of the present invention.
Dust sucked from the suction port 301 passes through the extension pipe 302 and the hose 303 and is collected in the cleaner body 201.

  FIG. 2 is a cross-sectional view of the main body of the vacuum cleaner according to an example of the embodiment of the present invention. Inside the vacuum cleaner main body 201, a dust collection chamber 202 having an open upper surface and an electric blower 203 are provided. A dust collection filter 204 for collecting the sucked dust is attached to the dust collection chamber 202. The dust collection filter 204 includes a mouth plate 205 made of a hard material such as cardboard and a bag member 206 bonded to the mouth plate 205, and is attached to the dust collection chamber 202 by the mouth plate 205.

  A lid 101 that can be opened and closed is provided at the upper part of the dust collection chamber 202 so that the dust collection filter 204 can be taken out. Further, a filter 102 for keeping the suction air clean is provided inside the lid 101 (on the dust collection chamber side), and is attached to the lid 101 with a filter holding member 103.

  Drawing 1 is a figure (figure which looked at a lid from the inside) of a vacuum cleaner concerning an example of an embodiment of the present invention. The filter 102 is housed in a filter housing portion 104 inside the filter holding member 103, and even if a dust collection filter 204 (not shown) swells around the outer periphery of the filter 102, the air flow between the inside of the lid body 101 and the dust collection filter 204 is reduced. A channel space 105 is provided so that the flowing channel does not disappear. The inlet 106 of the flow path space is greatly opened in front of the filter 102 to ensure the flow of wind to the electric blower 204 (not shown). As shown by the arrows in the drawing, the suction air enters from the lattice holes of the filter holding member 103 and is guided to the electric blower from the exhaust port 108 of the filter housing portion. Thereby, a wind actively flows to the filter 102 provided in the lid 101, and the suction air that passes through the dust and exits the dust collection filter can be cleaned. At the same time, suction air is always guided from the inlet 106 of the channel space to the channel space 105, and the dust collecting filter swells and sticks into the lid 101, thereby preventing a reduction in suction force due to the suction channel phenomenon. .

  FIG. 5 is a view of a filter holding member of a vacuum cleaner according to an example of the embodiment of the present invention. The filter holding member 103 is formed with flow passage walls 105a projecting toward the lid 101 on both sides. A filter storage wall 104 a that covers the filter storage unit 104 and protrudes toward the lid 101 is formed on the outer periphery of the filter storage unit 104. The filter storage wall 104a and the flow path wall 105a are in contact with the inside of the lid body 101, whereby the flow path space 105 is formed.

  The inlet 106 of the flow path space 105 is greatly opened in front of the filter storage section 104 to ensure a relatively large cross-sectional area. However, the flow path space 105 is located on the outer periphery of the filter storage section 104, and this embodiment In this form, the flow path is bifurcated. The exhaust port 107 in the channel space is located behind the filter 102 (not shown), and has a small cross-sectional area with respect to the inlet 106 in the channel space, but a plurality of exhaust ports 107 are provided to the electric blower 204 (not shown). The wind flow is secured. Thereby, without reducing the volume of dust that can be collected in the dust collection chamber, the suction force can be prevented from being lowered and the air can be actively passed through the filter, so that the suction air can be kept clean.

  FIG. 4 is a partially enlarged view around the filter holding member according to an example of the embodiment of the present invention. Since the mouth plate 205 of the dust collection filter 204 is located closer to the electric blower side (not shown) than the inlet 106 of the flow path space, it is prevented that the inlet 106 of the flow path space is blocked by the swollen dust collection filter. doing. In addition, the length from the inlet 106 of the channel space to the exhaust port 107 of the channel space, that is, the length of the channel space 105 is longer than the filter storage unit 104 in the direction of the air flow (the arrow direction in the drawing). Since it is provided, the flow path space is prevented from being blocked by the swelled dust collection filter.

  FIG. 6 is an external view of a main body of a vacuum cleaner according to an example of the embodiment of the present invention. The lid 101 provided on the cleaner body 201 is formed of a substantially transparent member to improve the design. Further, since the opaque member 601 is provided in a portion located outside the flow path space (not shown), the flow path space can be hidden from the outside, and the appearance is not impaired. Instead of the opaque member 601, the shaded portion can be covered with paint or the like. Furthermore, since the outside of the filter housing portion 104 is not covered with an opaque member, the filter is exposed to external light such as ultraviolet rays, so that the effect of a filter that activates using external light can be effectively utilized.
