Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a vacuum cleaner in which a suction port to which a dust suction hose is connected is formed on the upper surface of the main body case.

[Prior art]

Figures 6 and 7 show, for example, a conventional vacuum cleaner shown in Japanese Utility Model Publication No. 48-42760, which has an opening/closing lid on the top surface of the main body and a suction port to which a dust suction hose is connected to the top surface of the opening/closing lid. FIG. 6 is a cross-sectional side view of the main part in the cleaning state, and FIG. 7 is a cross-sectional side view of the main part in the filter dust removal state.

In the figure, 87 is the main body of the vacuum cleaner, 88 is a dust collection case, 89 and 90 are filters, 91 is a collection filter, 91 is an opening/closing lid that covers the top of the dust collection case 88, and 92 and 93 are the filters 89 and 90. A scraping brush 94 slides on the lower and upper surfaces, and 94 is a dust suction hose. Reference numeral 95 denotes a suction cylinder, and inside this suction cylinder 95 there is a flange 9 having a suction port 96 at the center and a knob 97 at the upper edge.
A rotary cylinder 99 having an integrally formed rotary cylinder 99 is rotatably attached and is prevented from coming off in the axial direction.
And under this rotary cylinder 99 is a scraping brush 9.
2 and 93 are fixed, and the lower side thereof fits into the dust removal hole 100 of the filter 89 as shown in FIG. When the filter 89 or 90 is about to become clogged, the user pulls out the suction pipe 94, grasps the knob 97, and rotates the rotating cylinder 99 in any direction. At this time, since the dust removal hole 100 is in an open state, the scraping brushes 92 and 93 are scraping off the fine dust captured by the filters 89 and 90.

Next, Figures 8 to 10 show the conventional vacuum cleaner shown in Japanese Utility Model Publication No. 17346/1973, and Figure 8 shows the front view with the cover of the hose connection to the suction port removed. 9 is a side view of the same as above, and FIG. 10 is a partial cross-sectional view taken along line A--A in FIG. 8.

In the figure, 110 is a dust suction hose, 111
11 is a connection part of the dust suction hose 110 on the suction port side of the vacuum cleaner body; 112 and 113 are terminal pieces that are connected when the electrode on the suction port side and the hose 110 are connected;
4, 115 is a sliding conductor connected to the operation panel of the remote circuit of the hose 110; 116, 117;
connects the terminal piece 112 and the sliding conductor 114 to the terminal piece 1
13 and the sliding conductor 115 electrically. 118 is a locking claw for locking the hose 110 to the suction port of the cleaner body.

Although the connection part 111 cannot be removed from the hose 110, the hose 110 cannot be removed from the connection part 1.
11, and this connecting portion 111 was fitted into the suction port of the main body of the vacuum cleaner.

Next, FIG. 11 is a cross-sectional view of a conventional vacuum cleaner disclosed in, for example, Japanese Utility Model Publication No. 17750/1980, in which a suction port to which a dust extraction hose is detachably connected is provided in the main body case.

In the figure, 129 is the vacuum cleaner body, 121 is an electric blower, 122 is a dust collecting cylinder, 123 is a cloth bag provided inside the dust collecting cylinder 122, 124 is a front lid, and 125 is a suction inlet of the front lid 124. 126 is a check valve made of a soft rubber material; 127 is a rear lid; and 128 is an intake hole in the rear lid.

As shown in FIG. 11, a conventional vacuum cleaner is provided with a check valve 126 made of a soft rubber material, and when the hose is not connected to the suction port 124, it closes the suction port 124 and closes the inside of the vacuum cleaner. This was to prevent the accumulated dust from leaking outside.

FIG. 12 is a sectional view of a main part of a dust suction port of a central type dust suction device installed in a building, as disclosed in, for example, Japanese Utility Model Publication No. 51-22551.

In the figure, 135 is a side wall of the building, 130 is a cylinder buried in the side wall 135, 131 is a dust intake port,
132 is a lid that naturally falls inside the cylinder 130 and closes the dust suction port 131; 133 is a handle provided on the lid 132; and 134 is a dust suction pipe that is connected to the dust suction port 131 opened by pushing up the lid 132 with the handle 133.

Since the device shown in FIG. 12 is intended for a central type dust suction device installed in a building, the dust suction port 131 is provided on one fixed side wall 135, and the dust suction port 131 is provided on a fixed side wall 135. Dust suction hose 1 connected to the dust suction port 131 inside the room on the side
34, and is different in structure and target from ordinary vacuum cleaners.

Additionally, USP3449787 shows a device with a lid attached to the connection port of a dust collector installed at the rear of the car, but the hose only faces forward, and the hose cannot be rotated. Even if I try to do so, the rear window glass and lid prevent the hose from rotating, and in addition, this connection port has a gap in the connection port for extending the hose from the dust collector to the inside of the car. Like the dust suction device shown in the figure, it is different in structure and object from a normal vacuum cleaner.

[The problem that the idea aims to solve]

In the conventional vacuum cleaner as shown in FIGS. 6 and 7, the rotary barrel 95 and the dust removal brushes 92 and 93 of the filters 89 and 90 are rotatably provided to drive them. When the suction hose 94 is inserted and used for cleaning, the lower side of the dust suction hose 94 is fitted into the dust removal hole 100 of the filter 89, and the dust suction hose 94 is inserted into the dust removal hole 100 of the filter 89.
cannot be rotated, so if you try to clean in a direction other than the front when the dust suction hose 94 is facing the front as shown in Figure 6, the direction of the vacuum cleaner body 87 will always change. , the direction of the vacuum cleaner body 87 must be changed, and when the direction of the vacuum cleaner body 87 is changed, the entire vacuum cleaner body 87 must be A load due to its own weight is applied, which causes problems such as crushing, distortion, and damage to the hose 94 and the main body 87.

In the conventional vacuum cleaners shown in Figs. 8 to 10, the hose rotation mechanism and electric contact mechanism are integrally formed on the hose side, so that the hose cannot be hit when the hose is removed or when it is in the removed state. External pressure from stepping on the hose is likely to damage or distort the rotating mechanism and electrical contact mechanism of the hose, and furthermore, the user must grasp the rotating mechanism and electrical contact mechanism themselves when connecting or disconnecting the hose. Because it does not, it is more prone to breakage and distortion, leading to problems with durability.

Furthermore, in the conventional vacuum cleaner shown in FIGS. 6 and 7, when the dust suction hose 94 is removed, the suction port 9
6, the outside air and the inside of the dust collection case 88 are always in communication, so the dust collected in the dust collection case 88 tends to scatter, making it extremely unsanitary.Furthermore, since the suction port is on the top, it is difficult to use the case. There was a problem in that the person had to directly look at the dust accumulated inside the dust collection case 88, making it look very unsightly.

In the conventional vacuum cleaner as shown in FIG. 11, the suction port 124 is simply blocked by a check valve 126 made of soft rubber, so it may open due to deterioration of the check valve and the inside may leak. There were problems in that it was unsanitary because the accumulated dust would scatter, and it was also unsightly as the inside of the suction port could be seen directly when the hose was not connected.

This invention was made to solve such problems in vacuum cleaners, and the purpose is to provide a sanitary vacuum cleaner in which the dust suction hose is detachable and rotatable.

[Means to solve the problem]

The vacuum cleaner according to this invention is equipped with a lid that can be opened and closed on the top surface of the main body, and a suction port to which a dust suction hose is connected is provided on the top surface of the lid. An inner lid attached to form a storage space separated from the room side is provided, and a rotating tool is provided in the storage space, facing the suction port and holding the dust suction hose detachably and 360° rotatably. , when the dust suction hose is not connected to the suction port between the suction port and the rotary tool, the dust collection filter side and the outside of the main body case are partitioned, and the upper surface of the main case is tilted in the direction of inclination. A shutter having a sliding knob is provided, a storage space for the shutter is formed inside the main body case above the slope of the upper surface of the main body case with respect to the suction port, and a storage space for the shutter is formed on the storage space side of the suction port. A knob storage space is formed to store the knobs.

[Effect]

In the vacuum cleaner of this invention, the hose itself is detachable and rotatable 360 degrees, and a rotary mechanism is installed inside the opening/closing lid inside the main body, so it is possible to remove dirt and dust during cleaning and non-cleaning. The rotary tool of the opening/closing lid is more reliably protected from dirt and is less likely to be damaged or distorted when taking out the lid, making it highly durable. It is hygienic as it prevents scattering, and looks good as the inside of the dust collection chamber cannot be seen through the suction port on the top of the main unit.The shutter can be opened and closed extremely easily using the knob.
Moreover, since the knob is located in the knob storage area when the shutter is opened, there is no need to worry about attaching or detaching the hose to the suction port.

Since a knob storage space is formed in which the knob is stored, the hose itself is detachable and rotatable 360 degrees, and a rotating mechanism is provided inside the opening/closing lid inside the main body, so when cleaning, The rotary tool of the opening/closing lid is more reliably protected from dirt and less likely to be damaged or distorted, both when not cleaning or when taking out trash, and is highly durable. It is hygienic because it prevents dust from scattering outside, and it looks good because the inside of the dust collection chamber cannot be seen through the suction port on the top of the main body.The shutter can be opened and closed very easily from above using the knob. Furthermore, since the knob is located in the knob storage area when the shutter is opened, it has the unique effect of not getting in the way of attaching or detaching the hose to the suction port.

Furthermore, since the shutter is installed along the slope of the top surface of the main body case, a portion of the shutter's own weight acts perpendicular to the slope and acts as a force that prevents the shutter from moving, so there is no concern that the shutter will move. Since there is no pressure and part of the shutter's own weight acts in the direction of movement of the shutter along the slope, the shutter can be moved with a small amount of force, and since the storage space for the shutter is above the suction port, This has a unique effect in that the force in the direction of shutter movement always acts in the closing direction.
