  Embodiment of the vacuum cleaner of this invention is described with reference to figures. 1-3 is an example of a vacuum cleaner main body, FIG. 1 is a perspective view of the main body, FIG. 2 is a side view of the main body, and FIG. 3 is a side sectional view of the main body. The vacuum cleaner is composed of a dust collection unit 1 and an electric blower storage unit 2, 3 is a dust collection chamber having a dust compression function, and 4 is an electric blower.

  When throwing away the dust collected in the dust collecting chamber of the dust collecting section, it is usual to throw the garbage down with the dust throwing port of the dust collecting chamber down. However, static electricity is generated inside the dust collection chamber due to the centrifugal force of the air, and fine dust sticks, and there is a problem that fine dust does not fall just by putting the dust disposal port down. Therefore, the present invention solves the problem of dust separation when throwing away trash. Since various types of dust collecting chambers of the dust collecting unit (hereinafter also referred to as a dust box) used in the vacuum cleaner can be considered, various embodiments of the vacuum cleaner of the present invention will be described below with reference to the drawings. explain.

  Next, an embodiment of a dust collecting unit used for a vacuum cleaner will be described with reference to the drawings. FIG. 4 is a perspective view of the dust collecting unit removed from the main body of the vacuum cleaner, FIG. 5 is a side sectional view of the dust collecting chamber, and FIG. 6 is a side sectional view of the dust collecting chamber at the time of throwing away trash. In the figure, 1 is a dust collecting part (dust box), 3 is a dust collecting chamber (dust cup), 4 is an electric blower, 5 is a filter, 6 is a dust box cover, 7 is a filter fixture, 8 is packing A, and 9 is packing. B and 10 are garbage.

  The dust collecting part 1 of the cyclone type vacuum cleaner has a configuration shown in FIG. Inside the dust collection chamber 3 being cleaned, air is rotated by centrifugal force and is in a state of being charged with static electricity. The lid of the dust collection chamber 3 is composed of a dust box cover 6, a filter fixture 7, packing A8, and packing B9. Even if the lid is opened and the trash is thrown away, the fine dust adhered to the inside of the dust collection chamber 3 due to static electricity. Dust does not fall. Therefore, Teflon (registered trademark) processing is applied to the inside of the dust collection chamber 3 to suppress adhesion of fine dust due to static electricity.

  FIG. 6 shows a side cross-sectional view of the dust collection chamber when the trash is thrown away. When the lid is opened to throw away the dust 10 in the dust collection chamber, Teflon processing is applied to the inside of the dust collection chamber 3 to suppress the adhesion of fine dust due to static electricity, so the dust 10 can be thrown away with one touch. The time and labor required for throwing away dust in the dust collection chamber can be greatly reduced.

  Next, another embodiment of the dust collection unit used in the vacuum cleaner will be described with reference to the drawings. FIG. 7A is a front cross-sectional view of the main body of the vacuum cleaner, and FIG. 7B is a side cross-sectional view along the AA plane. FIG. 8 shows a situation where garbage is thrown away from the dust collection chamber. In the figure, reference numeral 11 denotes an elastomer material which is rubber or a deformable resin, and a part of the resin portion forming the dust collecting chamber is formed of rubber or an elastomer material. The same components as those in FIGS. 5 and 6 are denoted by the same reference numerals.

  The feature of this embodiment is that, as shown in FIGS. 7 and 8B, a part of the resin portion forming the dust collecting chamber 3 is formed of rubber or elastomer material 11 processed by insert molding. It is. Here, a state in which the dust 10 collected in the dust collection chamber is discarded will be described with reference to FIG. FIG. 8A is a configuration diagram of a conventional dust collection chamber, and the dust collection chamber 3 is formed only of resin. Dust is thrown down with the dust collection port of the dust collecting unit 1 down, but the dust 10 sticks to the inside of the dust collection chamber 3, and the dust 10 falls at once only by putting the dust collection port down. Absent.

  On the other hand, in the case where the rubber or elastomer material 11 of the present invention shown in FIG. 8B is used as a part of the resin portion forming the dust collection chamber 3, the dust collection chamber 3 is disposed when the dust 10 is discarded. The dust 10 stuck to the inside of the dust collection chamber 3 can be dropped by pushing the rubber or elastomer material 11 portion in a horizontal direction, and the rubber or elastomer material 11 can be pushed down.

  When separating dust in the dust collection part of a cyclone vacuum cleaner, if the dust separation part and the dust collection chamber are divided, dust may be caught at the dust collection part entrance or dust collection. When a mechanism for compressing dust in a room is added, there is a problem that dust is difficult to drop from the dust collection chamber when the dust is discarded due to the compression force. At that time, a part of the dust collecting part was formed of an elastomer material, and a mechanism for pushing out the clogged dust was added, and the dust could be thrown away with one touch. However, when the vacuum cleaner is operated, the elastomer part is sucked inward by the suction force, and there is a problem that the dust collection capacity is reduced. Therefore, the present embodiment solves this drawback.

  Next, another embodiment of the dust collecting unit used in the electric vacuum cleaner of the present invention will be described with reference to the drawings. FIG. 9 is a plan sectional view of the dust collecting portion, FIG. 9 (A) is a plan sectional view of the dust collecting portion without deformation of the elastomer, and FIG. 9 (B) is a plan view of the dust collecting portion when the elastomer is deformed. It is sectional drawing. FIG. 10 is a plan sectional view and a side sectional view when the dust collecting portion of the present embodiment is fixed to the main body. In the figure, 3 is a dust collection chamber having a dust compression function, 4 is an electric blower, 12 is a centrifugal separation mechanism for separating dust formed by a flow path, 13 is a mesh portion, 14 is a bypass flow path, and 15 is dust. A filter, 16 is a hook-shaped rib, and 17 is a rib of the cleaner body.

  This embodiment will be described with reference to the drawings. FIG. 9 is a plan cross-sectional view of the dust collecting portion, and the dust sucked from the suction port 4 is collected in the dust collecting chamber 3 through the flow path 12. At this time, the air passes through the mesh part 13, passes through the bypass flow path 14, and clean air that has passed through the dust filter 15 flows into a motor (not shown) of the electric blower.

  Part of the dust collecting portion 1 is formed of an elastomer material 11, and a hook-shaped rib 16 is integrated therewith. As shown in FIG. 9B, the elastomer portion 11 can be deformed. The dust is pushed out by pressing the elastomer 11 when thrown away when the dust caught at the entrance of the dust collection chamber or the compressed dust collects in the dust collection chamber.

  When the dust collecting unit 1 is attached to the main body, the hook-shaped ribs 16 of the dust collecting unit 1 are hooked and fixed to the ribs 17 of the cleaner main body as shown in FIG. In this way, by providing a mechanism for hooking and fixing resin parts to a part of the main body, when the cleaner is operated, the elastomer part is not sucked inward, so the dust collection capacity during operation is reduced. Sufficient capacity can be ensured without decreasing.

  As a result, the resin part in a shape that can be hooked with the elastomer in the dust collection chamber is integrated, and the resin part is hooked and fixed to a part of the main body when the main body is mounted. To prevent. Thereby, it is possible to add a dust pushing mechanism while securing a dust collection capacity.

  In vacuum cleaners with a dust collection unit that can be disposed of when collecting and throwing away garbage, such as cyclone vacuum cleaners, the dust flows from the dust collection chamber to the motor in order to compress the dust in the dust collection chamber. A compression mesh was provided on the road. However, the mesh for compression caused clogging at an early stage when fine dust was sucked in, so that the dust could not be sufficiently compressed and the work rate was lowered. Therefore, the present embodiment solves this drawback.

  Next, other embodiments of the dust collecting unit used in the electric vacuum cleaner of the present invention will be described with reference to FIGS. 11 is a partially broken sectional view and a side sectional view of the front surface of the dust collecting unit, FIG. 12 is a perspective view of a filter in the dust collecting unit, and FIG. 13 is a side sectional view showing a positional relationship between the filter and the electric blower. In the figure, the same components as those in FIGS. 9 and 10 are denoted by the same reference numerals.

  In a normal vacuum cleaner, the size of the filter 15 is sufficient if it covers the front (suction port) of the electric blower 4, but in the case of a cyclone vacuum cleaner, the filter clogs very quickly and sucks in dust. If you continue to do so, you will not be able to compress the garbage enough, and the work rate will drop.

  As shown in FIG. 13, by providing the filter 15 with an area that covers the entire area of the dust collecting part (dust box), the surface area of the filter 15 can be increased, and clogging of the filter 15 can be greatly reduced. There is an effect that it is possible to moderate the reduction of the work rate when the dust is continuously sucked. Moreover, by having the filter part 18 of the part which is not in front of the electric blower 4 (suction inlet), clogging of the filter 15 can be partially dispersed, and the degree of reduction in the work rate can be reduced.

  In this way, in the dust collection part of the vacuum cleaner, the filter in the dust box is made up of a filter that has the full area of the dust box on the side of the dust box, reducing filter clogging and sucking in dust. The degree of decrease in the work rate when continued can be moderated.

  Next, another embodiment of the dust collecting unit used in the electric vacuum cleaner of the present invention will be described with reference to FIGS. 14 and 15. FIG. 14 is a side sectional view showing the positional relationship between the filter and the electric blower, and FIG. 15 is a plan sectional view showing the positional relationship between the filter and the electric blower. In the figure, 19 is an upper filter, 20 is a lower filter, and the same components as those in FIG.

  This embodiment is a modification of the above-described embodiment 4 and aims to increase the surface area of the filter. In the side sectional view of FIG. 14, an upper filter 19 and a lower filter 20 are provided above and below the one-side filter 15 as a filter in the dust collecting portion (dust box) 1 in addition to the ordinary one-side filter 15. With the motor of the electric blower 4, the wind flows as shown by arrows so as to pass through the respective filters 15, 19, 20 as shown in FIG. 14.

  In the plan sectional view of FIG. 15, a right filter 21 and a left filter 22 are provided at both ends of the one-side filter 15 as a filter in the dust collecting unit 1 in addition to a normal one-side filter 17. With the motor of the electric blower 4, the wind flows as shown by arrows so as to pass through the respective filters 15, 21, 22 as shown in FIG. 15.

  As described above, it is usually sufficient that the filter covers one surface of the electric blower 4 (suction port). However, as shown in FIGS. By constructing the entire top, bottom, left, and right with 19, 20, 21, and 22, the surface area of the filter can be dramatically increased, and the clogging of the filter can be dispersed without concentrating on a specific place and greatly reduced. Can be reduced, and the degree of decrease in the work rate when the dust is continuously sucked can be moderated.

  In vacuum cleaners, it is common to place a filter so that fine dust does not flow to the motor, but such a filter clogs each time fine dust is collected and eventually flows. Since the road is blocked, care is required to eliminate clogging. Therefore, when a pleated filter is used for this filter, the shape thereof is a series of peaks and valleys, so that the maintenance is troublesome. Therefore, the present embodiment solves this drawback.

  Next, an embodiment of a filter used in the electric vacuum cleaner of the present invention will be described with reference to FIG. FIG. 16A is a development view of the pleat filter, FIG. 16B is a partially enlarged view of the pleat filter, and FIG. 16C is a state diagram showing expandability of the pleat filter. In the figure, 23 is a pleated filter, and 24 is a soft material such as an elastomer.

  In the vacuum cleaner, the air flows into the dust collecting portion from the intake air inlet, passes through the pleated filter 23, and clean air flows into the electric blower. At that time, the pleated filter 23 is gradually clogged with fine dust. Therefore, as shown in FIG. 16B, the pleated filter 23 is covered with a soft material 24 such as an elastomer.

  At this time, the elastomer 24 connects the gaps between the mountains of the pleat filter 23 on the air flow side. With this shape, as shown in FIG. 16 (C), it becomes possible to greatly widen the pleated valley portion, improve the ease of cleaning when removing dust stuck to the pleated valley portion, The effect is that the trash can be dropped down as it is.

  In this way, all the pleats on one side (the side where the flow path exits) are connected with the soft resin so that they do not fall apart. In this state, the overall shape of the pleats can be opened greatly without breaking the shape of the pleats on the side where the dust is collected (the side where the flow path enters). Can be dropped.

  In a vacuum cleaner, a filter is arranged so that fine dust does not flow to the motor of the electric blower, but care is required to recover the clogging of the filter. In particular, when a pleated filter is used as a filter, a mechanism such as dust removal with a brush or the like to remove clogging of the filter or vibration removal is added. This embodiment proposes a novel means capable of automatic dust removal.

  Next, another embodiment of the filter used in the electric vacuum cleaner of the present invention will be described with reference to FIGS. 17 is a side sectional view of the main body of the vacuum cleaner equipped with the filter of the present invention, FIG. 18 is a pleat filter when removed from the main body of the vacuum cleaner, FIG. 19 is a front view when a dust removing brush is attached to the pleat filter, and FIG. It is a pleated filter at the time of wearing. Reference numeral 23 denotes a pleated filter, 25 denotes a dust removing brush, 26 denotes a shaft, and 27 denotes an engaging claw.

  When the dust removing brush is attached to the pleated filter, as shown in FIG. 19, the dust removing brush 25 is disposed so as to be opposed to the pleated filter 23. A mechanism for removing dust from the pleated filter 23 is configured by moving the dust removing brush 25 up and down while in contact with the pleated filter 23 in the dust collecting portion.

  In FIG. 17, the dust collector 1 is fixed to the upper portion of the pleat filter 23 when the dust collector 1 is removed upward from the cleaner body from the state where the dust collector 1 is attached to the cleaner body (FIG. 18A). The shaft 26 connected to the dust removing brush 25 is hooked on the engaging claw 27 connected to the bottom surface of the cleaner body, and the dust removing brush 25 moves to the lower part of the pleat filter 23 (FIG. 18B). , Remove the accumulated garbage. Thereafter, by applying a force, the shaft 26 is detached from the cleaner body (FIG. 18C), and the dust collecting unit 1 can be removed.

  When the dust collecting unit 1 is mounted on the cleaner body, the shaft 26 comes into contact with the engagement 27 connected to the cleaner body (FIG. 20A), and the dust removing brush 25 is located above the pleat filter 23 from the bottom. (FIG. 20 (B)) and force is applied, the shaft 26 engages with the engaging claw 27, and the dust collecting part 1 is fixed to the cleaner body (FIG. 20 (C)). Thus, automatic dust removal can be performed when the dust collecting unit is attached or detached.

  Thus, automatic dust removal is possible by providing a mechanism for removing the filter by moving the brush in contact with the filter in the dust collector up and down when the dust collector is attached and detached.

  When the pleat filter of the vacuum cleaner dust collection unit prevents fine dust from flowing out, the frame of the pleat filter is made of an opaque resin, and the dust collection unit is used for a dust press. Covered with a mesh filter, it is difficult to see where the pleated filter is located, and the stains on the pleated filter are not visible. Therefore, even if the pleat filter is clogged, the vacuum cleaner will be used, and it will become a kind of low load state and overspeed, which will cause the temperature of the vacuum cleaner body to rise and the motor to be abnormal / noise. . In view of this, this embodiment makes it possible to visually check the degree of contamination of the pleated filter, thereby eliminating such drawbacks.

  Next, another embodiment of the filter used in the electric vacuum cleaner of the present invention will be described with reference to a side sectional view of the dust collecting portion in FIG. In the figure, 6 is a dust box cover, 7 is a transparent filter fixture, 23 is a pleated filter, 28 is a surface on which fine dust adheres to the pleated filter 23, and 29 is a mesh filter for dust press.

  The frame body of the pleated filter 23 includes a dust box cover 6 and a filter fixture 7. The surface 28 to which fine dust adheres to the breez filter 23 is covered with a dust press mesh filter 29 and cannot be visually observed. Therefore, by making the dust box cover 6 and the filter fixture 7 transparent, the surface 28 on which fine dust adheres to the pleated filter 23 can be visually observed. In this way, by making the frame of the pleated filter 23 transparent, it is possible to visually check the stain on the pleated filter.

  When the urethane filter in the dust collection part of the vacuum cleaner prevents the fine dust from flowing out of the vacuum cleaner body, the urethane filter frame is made of opaque resin, and the dust collection part Is covered with a dust filter mesh filter, and it is difficult to see where the urethane filter is located, and the degree of contamination of the urethane filter is not visible. Therefore, even if the urethane filter is clogged, the vacuum cleaner will be used, and it will become a kind of low load and overspeed, which will cause the temperature of the vacuum cleaner body to rise and the motor to be abnormal or abnormal. . In view of this, this embodiment makes it possible to visually check the degree of contamination of the urethane filter, thereby eliminating such drawbacks.

  Next, another embodiment of the filter used in the electric vacuum cleaner of the present invention will be described with reference to a side sectional view of the dust collecting portion in FIG. In the figure, 6 is a dust box cover, 7 is a transparent filter fixture, 28 is a surface on which fine dust adheres to a urethane filter, and 29 is a mesh filter for dust press.

  In FIG. 22, the frame body of the urethane filter (blue) 30, the urethane filter (yellow) 31, and the urethane filter (red) 32 includes a dust box cover 6 and a filter fixture 7.

  The surface 28 where fine dust adheres to the urethane filter (blue) 30 is covered with the dust filter mesh filter 29 and cannot be visually observed. By making the dust box cover 6 and the filter fixture 7 transparent, the surface 28 on which fine dust adheres to the urethane filter (blue) 30 can be visually observed.

  In addition, since fine dust gradually enters the inside of the urethane filter, the fine dust uses the boundary line between the urethane filter (yellow) 31 and the urethane filter (red) 32 as a cleaning sign, and the sides of the urethane filters of different colors are visually observed. You can check it easily. Here, the urethane filter can be formed of two layers of two colors or three layers of three colors.

  Thus, by making the frame of the urethane filter transparent, the dirt on the urethane filter can be visually observed. In addition, since fine dust enters the inside of the urethane filter little by little, if the color of the filter is changed to form a multilayer urethane filter and enters the boundary line of the final urethane filter layer, it can be used as a cleaning sign.

  For example, as shown in the side sectional view of the dust collecting unit in FIG. 23, the urethane filter, the pleat filter 23, etc. of the dust collecting unit of the vacuum cleaner for preventing the outflow of fine dust to the outside of the vacuum cleaner body are dust. When covered with a press mesh filter, the frame of the pleat filter 23 is composed of a dust box cover 6 and a filter fixture 7.

In the conventional filter of FIG. 24, as shown in FIG. 24 (A) is a side sectional view of the filter, and FIG. 24 (B) is a plan view of the filter, the surface on which fine dust adheres to the urethane filter or the breezes filter 23.
