[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cyclone-type vacuum cleaner that removes dust from an intake flow by generating a spiral flow in a cylindrical dust collection chamber, and particularly has a compact form while improving dust collection efficiency. It relates to a vacuum cleaner.
[0002]
[Prior art]
The conventional vacuum cleaner is a vacuum cleaner having a disposable dust collecting bag, but in recent years, a vacuum cleaner called a cyclone method has attracted attention.
[0003]
This cyclone-type vacuum cleaner has a cylindrical dust collecting chamber, an intake port for taking in air from a circumferential direction on an upper side face of the dust collecting chamber, and a central axis below the cylindrical dust collecting chamber. An exhaust port is provided in the exhaust port, and a blower for discharging air from the dust collection chamber is attached to the exhaust port.
[0004]
According to this cyclone type vacuum cleaner, the air flow containing dust sucked in from the air inlet forms a spiral flow along the cylindrical inner wall surface, and from the upper part to the lower part of the cylindrical inner wall surface. It flows and is discharged out of the dust collecting chamber from the discharge port. At this time, the dust contained in the swirl flow moves along the inner wall surface of the dust collection chamber and is collected at the bottom of the dust collection chamber, and the airflow is discharged leaving the dust in the dust collection chamber, so that the electric cleaning is performed. Can function as a machine. Such a cyclone-type vacuum cleaner is disclosed in, for example, JP-A-2002-17636.
[0005]
[Problems to be solved by the invention]
Since the cyclone-type vacuum cleaner employs a cylindrical dust collection chamber, miniaturization of the main body is a major issue. For example, in the conventional example, the dust collection chamber is arranged in the front portion of the main body in a vertical position to reduce the size, but since the cylindrical dust collection chamber is arranged in the vertical position, the overall height is increased, Still, the overall sense of volume is growing. Furthermore, the cyclone method has a problem that large dust can be removed but small dust cannot be removed easily. Therefore, a filter for collecting small dust is provided between the dust collection chamber and the blower. Therefore, in the cyclone method, it is necessary to remove dust adhering to the filter. Therefore, it is also important to reduce the number of times of cleaning the filter. That is, it is an issue to increase the dust collection efficiency in front of the filter. Furthermore, improvement of maintenance of these dust collection chambers and filters is also an issue.
[0006]
Therefore, an object of the present invention is to provide a vacuum cleaner capable of reducing the size while improving the dust collection efficiency.
[0007]

[0031]
On the other hand, a blower 108 provided in a blower room 127 is attached to the rear passage 126 in close contact with the ventilation hole 131b. In this embodiment, the blower 108 is placed in a horizontal position in which the blower 108a with a built-in fan is adjacent to the rear passage 126, that is, the rotation axis of the drive unit 108b disposed on the left side of the blower 108a is in the horizontal position. It is arranged in the blower room 127 in a different posture. Thereby, the main dust collection chamber 107 and the blower 108 can be communicated linearly, so that the suction efficiency can be improved.
[0032]
Further, since the main dust collecting chamber 107 and the blower 108 which are arranged horizontally communicate with each other through a linear ventilation path (a front ventilation path 123 and a rear ventilation path 126) perpendicular to the main ventilation chamber 107, the front ventilation path 123 It is possible to secure a space for arranging the first filter 141 having a sufficient size and the second filter 142 having a sufficient size in the rear ventilation passage 126.
[0033]
Further, since the power supply chamber 128 is disposed on the left side of the blower room 127, that is, adjacent to the drive unit 108b side, the power supply room 128 is discharged from the blower unit 108a into the blower room 127 through the drive unit 108b (to be cooled). Can be easily guided into the power supply chamber 128.
[0034]
The power supply chamber 128 houses a charging pack 109a including a plurality of rechargeable batteries. Various types of rechargeable batteries can be used as the rechargeable battery constituting the charging pack 109a. In the present embodiment, the rechargeable battery (19.2 volts, weight 870 g) obtained by combining 16 cylindrical rechargeable batteries (cells) is used. Is adopted. In this embodiment, the column-shaped rechargeable batteries are arranged in two vertically and vertically, with the longitudinal direction of the rechargeable batteries being aligned with the vertical direction of the cleaner body 100, and are arranged in four rows in the front-rear direction and in the left-right direction. The charging pack 109a has a substantially rectangular parallelepiped shape having two rows. In the power supply chamber 128, a charging terminal portion 144 exposed on the back surface of the cleaner main body 100 is formed.
[0035]

A substrate 115 is disposed by utilizing the same. The side space 145 is supplied with the airflow sent into the power supply chamber 128 and discharged to the outside from an exhaust port 146 formed in the side space 145. At this time, a part of the airflow exhausted to the outside flows into the side space 145, so that the substrate 115 can be cooled.
[0036]
3, 4, and 5, in this embodiment, the sub-dust collection chamber 110 is provided adjacent to the column-shaped main dust collection chamber 107. For example, in this embodiment, the dust collection case 133 is formed in a substantially track-shaped cross-section, and the partition wall 147 is provided so that the main dust-collection chamber 107 is formed in a circular cross-section. I have. The main dust collecting chamber 107 and the sub dust collecting chamber 110 are communicated by a communication port 136 (see FIG. 3) formed in the partition wall 147 near the bottom of the cup shape. The dust separated in the main dust collecting chamber 107 is collected in the sub-dust collecting chamber 110 through the communication port 136, and the accumulation of dust in the main dust collecting chamber 107 is reduced. Note that, in this embodiment, the sub-dust collection chamber 110 has a shape in which one side is opened similarly to the main dust collection chamber 107, and the opening is closed by the dust collection cover 134.
[0037]
Further, in this embodiment, the main dust collection chamber 107 is attached to the dust collection case storage chamber 122, and the sub dust collection chamber 110 is attached so as to be located below. In this embodiment, the diameter of the main dust collecting chamber 107 is made smaller than the diameter of the blowing part 108a of the blower 108, and the long diameter (the vertical height) of the track-shaped dust collecting case 133 is set to The length is set to be substantially the same as the diameter of the blower 108 a of 108. Thereby, the compact cleaner main body 100 having a small actual length and a sufficient space for the sub-dust collection chamber 110 can be provided while realizing the cleaner main body 100 with the front-rear length of the cleaner main body 100 being small and flat. Has been realized.
[0038]
In the case of a cyclone type dust collecting chamber, in order to take in an air flow containing dust into the dust collecting chamber, a good spiral flow is formed unless the air intake 135 is directed in the circumferential direction. I can't. In this embodiment, since the main dust collecting chamber 107 is arranged in a horizontal direction, in a case where an air inlet 135 in the circumferential direction is provided in the horizontally arranged main dust collecting chamber 107, the hose of the suction hose 200 is used. The mounting portion 116 must be provided at an upper position or a lower position of the cleaner body 100. When attached to the upper position, the main body handle portion 104 provided above the hose attachment portion 116 protrudes largely upward. When the suction hose 200 is provided at a lower position, the suction hose 200 is attached to a position close to the floor surface, so that there remains a problem in traveling performance. Of course, the hose mounting portion 116 may be provided diagonally, but in this case, the suction hose 200 is mounted diagonally, and there remains a problem in the storability of the suction hose 200 during pulling travel and storage by the suction hose 200.
[0039]
In this embodiment, the hose mounting portion 116 is provided substantially at the center (vertical direction) of the cleaner main body 100 so that the main dust collecting chamber 107 can be mounted at a position higher than the center of the cleaner main body 100. By providing the sub-dust collection chamber 110 in the lower space of the main dust collection chamber 107, the mounting efficiency of the suction hose 200 is improved and the actual phase efficiency of the cleaner main body 100 is improved.
[0040]
Next, the flow of the intake air flow will be described with reference to FIGS. First, in this embodiment, by operating the operation switch 301 provided on the hand handle 300 shown in FIG. 1, this operation signal is transmitted to the hose mounting portion 116 via a signal line wired in the suction hose 200. This signal is transmitted to the substrate 115 via a signal line (not shown) wired in the cleaner main body 100, and the substrate 115 drives the blower 108.
[0041]
When the blower 108 is driven, the air flow including dust taken into the cleaner main body 100 from the suction hose 200 is exhausted to the outside of the cleaner main body 100 through the following path.
[0042]
First, the air flow drawn into the hose mounting portion 116 is drawn straight (see FIG. 4) into the air intake 135 formed obliquely in the circumferential direction without resistance (pressed low), and the main dust collection is performed. It is taken into the chamber 107. The captured airflow moves along with the dust along the inner circumferential surface of the main dust collecting chamber 107 from the right side to the left side of the bottom of the main dust collecting chamber 107 (upper portion in FIG. 3), that is, a vortex. From the vicinity of the center of the axis of the cylinder to the left side to the right side, and is guided to the tip of the cylindrical body 139 of the main dust collection cover 134. Here, the air flow is separated from the dust when turning from the left direction to the right direction, and the dust that is separated and still contained in the air flow is provided at the other end of the cylindrical body 139 provided on the main dust collection cover 134. It is removed by the net-shaped first filter 141. On the other hand, the dust separated in the main dust collecting chamber 107 moves from the communication port 136 formed near the bottom of the main dust collecting chamber 107 to the sub dust collecting chamber 110 and accumulates in the sub dust collecting chamber 110. Is done.
[0043]
Further, in this embodiment, since the main dust collecting chamber 107 is in the horizontal posture, dust remaining in the main dust collecting chamber 107 when the blower 108 is started is directly sucked by the first filter 141, and the dust separating efficiency is improved. It is feared that it will drop. However, in this embodiment, since the air flow is drawn out from the tip of the cylindrical body 139 provided at the center of the cylindrical main dust collecting chamber 107, the vortex flows between the cylindrical body 139 and the inner wall surface of the main dust collecting chamber 107. It moves while drawing a vortex and rotating. Therefore, when the power is turned off and the blower 108 stops, the dust falls under the cylindrical body 139, that is, between the cylindrical body 139 and the inner wall of the dust collecting case 133, and even if the blower 108 is started again. Since the dust dropped to the lower part of the cylindrical body 139 moves on the inner wall surface of the cylindrical shape and is sucked from the tip of the cylindrical body 139, it is possible to reduce the possibility that the dust is directly guided to the first filter 141. it can.
[0044]
The airflow from which dust has been removed by the first filter 141 passes from the linearly formed front passage 123 to the rear passage 126, passes through the second filter provided in the ventilation hole 131b, and further removes dust. And is taken into the blower 108a. Therefore, in this embodiment, since the ventilation path to the blower 108a is less bent, the loss of suction force is smaller.
[0045]
The air flow taken in by the blowing unit 108a is blown to the driving unit 108b to cool the driving unit 108b and to be sent to the blower room 127 around the driving unit 108b. A sound deadening material 148 is disposed in the blower room 127, and is led to the power supply room 128 through a ventilation hole 131 c provided in the partition wall 125 through a ventilation path (not shown) formed by the sound deadening material 148. In the power supply chamber 128, the airflow is cooled by passing the airflow around the charging pack 109a.
[0046]
Then, the airflow is sent from the power supply chamber 128 to the side space 145 adjacent to the power supply chamber 128, and is further exhausted to the outside through an exhaust port 146 formed in the side panel 114 adjacent to the power supply chamber 128. . At this time, a part of the airflow sent into the side space 145 is sent to the substrate 115 provided in the side space. Thus, the substrate 115 can be cooled.
[0047]
In this embodiment, the air flow is discharged from the exhaust port 146 adjacent to the power supply chamber 128 via the side space 145, but the present invention is not limited to this. For example, a passage (not shown) may be formed to communicate the airflow of the power supply chamber 128 to the side spaces 145 on both sides, and the side space 145 may be provided with an exhaust port 146 opening at a predetermined interval. . According to this embodiment, the air flow is dispersed and exhausted from the entire side surfaces of the cleaner main body 100. Therefore, the momentum of the exhaust air flow is reduced, so that dust is prevented from rising. It is possible to reduce discomfort to the user by hitting the foot or the like. Further, the cooling efficiency of the substrate 115 disposed on the side panel 114 can be improved.
[0048]
Next, with reference to FIG. 6 and FIG. 7, an appearance of the cleaner main body 100 of this embodiment will be described. 6A and 6B are external perspective views of the main body of the cleaner. FIG. 6A is a perspective view seen from the front side, and FIG. 6B is a perspective view showing another application example. 7A and 7B are external views of the main body of the vacuum cleaner, wherein FIG. 7A is a plan view, FIG. 7B is a front view, FIG. 7C is a bottom view, FIG. 7D is a left side view, and FIG. The figure is a rear view.
[0049]
6 and 7, the main body 100 of the vacuum cleaner according to the present embodiment has a flat appearance with a low overall height according to the internal device configuration. In this embodiment, a structure is provided in which the large wheel 101 does not touch the clothes of the user when the user uses the shoulder belt 106 (see FIG. 10C) to carry it on the shoulder.
[0050]
First, in this embodiment, the main dust-collecting chamber 107 having an internal horizontal attitude, the blower chamber 127 and the power supply chamber 128 arranged in parallel with each other are sandwiched by the side panel 114. When viewed from the side, the front and rear ends of the side panel 114 are rounded in accordance with the outer shapes of the dust collecting case 133 and the blower 108, so that the front and rear are provided with large roundness and both side surfaces have a flat appearance. It has a flat appearance. Thereby, the vacuum cleaner main body 100 having a small dead space and a low center of gravity is realized.
[0051]
