Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. It should be noted that this embodiment is an example and is not limited to this.

First, the usage state and the storage state of the vacuum cleaner 100 according to the present invention will be described with reference to the drawings. The configuration of the vacuum cleaner 100 according to the present invention will be described. The vacuum cleaner 100 according to the present invention has a first usage state in which the angle formed by the head 1 and the main body 2 as shown in FIGS. 1 to 3 is approximately 180 °, and the head 1 and the main body as shown in FIG. A second use state in which the angle formed by 2 can be freely changed and can rotate around the point A, and a state in which the angle formed by the head 1 and the main body 2 as shown in FIGS. 5 to 7 is approximately 90 °. It has three states of storage.

In the vacuum cleaner 100 according to the present invention, the head 1 and the main body 2 are rotatably connected to each other. The main body 2 is connected to the center of the head 1. With such a configuration, when the main body 2 is erected vertically on the head 1, the center of gravity of the main body 2 is located within the projected area of the head 1, so that the vacuum cleaner 100 falls down. There is no.

Here, the side where the head 1 is located is defined as the "front side" and the side where the main body 2 is located is defined as the "rear side" in the first use state. For example, in FIG. 1, the left side of the drawing represents the “front side” and the right side represents the “rear side”. In addition, the left and right are defined based on the person who operates the vacuum cleaner. For example, in FIG. 2, the lower side of the drawing shows the “left side” and the upper side shows the “right side”. In the case of FIG. 3, since the vacuum cleaner is viewed from the cleaning surface side, the upper side of the drawing is the “left side” and the lower side is the “right side”.

Next, the configuration of the vacuum cleaner 100 according to the present invention will be described with reference to the drawings. The vacuum cleaner 100 according to the present invention includes a head 1 having a suction port 12 and a main body 2 containing an electric blower, and the head 1 and the main body 2 are rotatably connected to each other.

The head 1 includes a suction port 12, a rear wheel 14, a sensor detection display unit 16, windows 18a and 18b, front wheels 20a and 20b, protrusions 22a and 22i, and tapping portions 24a and 24b. It is composed of a pile 26, an ultraviolet lamp 28, and grounding sensors 30a and 30b.

The main body 2 includes a main body side wheel 32, filter covers 34a and 34b, a battery cover 36, a grip portion 38, a dust collecting case 40, a release button 42, an operation switch 44, and a display portion 46.

The suction port 12 is provided at the lower part of the head 2 for sucking dust from the cleaning surface. As shown in FIG. 3, the suction port 12 is provided substantially in the center of the head 1 on the cleaning surface side. The structure of the suction port 12 may have a shape that merely has an opening as conventionally adopted, but may have a rotating member such as a brush inside the suction port 12. By having the rotating member, it is possible to scoop out dust on the cleaning surface, especially in a long-haired object such as a carpet, and to suck in more dust.

The rear wheel 14 is provided in the center of the rear side of the head 1. By providing the rear wheel 14, the vacuum cleaner 100 can be smoothly moved back and forth when the vacuum cleaner 100 is used in either the first usage state or the second usage state, so that the suction force can be obtained. This can prevent the vacuum cleaner 100 from sticking to the bedding and making it difficult to operate the vacuum cleaner 100. Although the rear wheel 14 of the present embodiment has a cylindrical shape, it may have a shape like a general tire.

The sensor detection display unit 16 displays the detection result of a sensor (not shown) provided in the vicinity of the suction port 12 of the vacuum cleaner 100 according to the present invention. The display method is to display according to the amount of dust detected by the sensor. The sensor detection display unit 16 in the present embodiment changes its color according to the amount of dust and the like. For example, if there is a lot of dust, it emits red light, and as the amount of dust decreases, it changes to yellow and green. Further, the sensor detection display unit 16 is composed of a substrate (not shown) on which a light emitting means (not shown) is mounted and a scattering plate covering the substrate. The light emitting means is a red and green light emitting diode in the vacuum cleaner 100 of the present invention. It is possible to create multiple colors by mounting a light emitting diode that emits multiple colors and adjusting the brightness of each light emitting diode. Further, by covering with a scattering plate, the light of the light emitting diode can be emitted from the entire scattering plate, and the visibility is improved.

The window portions 18a and 18b are provided on the left and right sides of the rear end portion of the head 1, respectively. An ultraviolet lamp 28, which will be described later, is provided below the windows 18a and 18b. When the ultraviolet lamp 28 is turned on, the state of lighting of the ultraviolet lamp 28 can be confirmed from the windows 18a and 18b. In the vacuum cleaner 100 according to the present invention, when the head 1 is turned over to see the lighting of the ultraviolet lamp 28, the safety mechanism operates and the ultraviolet lamp 28 is turned off. Therefore, the operator turns the head 2 over to turn the lighting state of the ultraviolet lamp 28. Cannot be confirmed. Therefore, by providing the windows 18a and 18b on the upper part of the head 2, it is possible to confirm whether or not the ultraviolet lamp 28 is operating without turning over the head 1. The members constituting the windows 18a and 18b may be transparent, but members with reduced transparency may be used. This prevents the emitted light of the ultraviolet lamp 28 from directly entering the eyes of the operator.

The front wheels 20a and 20b are provided on the front portion of the head 1 on the cleaning surface side. When the vacuum cleaner 100 is moved back and forth, it rotates on the cleaning surface together with the rear wheel 14, so that the head 1 can be smoothly moved on the cleaning surface.

The protrusions 22a to 22i are provided at the front end of the head 1 on the cleaning surface side. By providing a plurality of protrusions, a space is created between the cleaning surface and the suction port 12, so that it is possible to prevent the vacuum cleaner 100 and the cleaning surface from coming into close contact with each other. Although the vacuum cleaner 100 of the present invention is provided with nine protrusions, the number of protrusions may be larger or smaller than nine.

The tapped portions 24a and 24b are provided between the suction port 12 of the head 1 and the protruding portions 22a to 22i. By tapping the cleaning surface with the tapping portions 24a and 24b, it is possible to knock out and suck in the cleaning surface, particularly dust and the like in the back of the bedding, so that more effective cleaning becomes possible. The tapped portions 24a and 24b of the present invention are provided with two plates having protrusions on the surface over a width substantially the same as the width of the suction port 12. With this configuration, dust can be ejected over the entire width of the suction port 12 instead of only a part of the suction port 12, so that cleaning can be performed efficiently. Although the vacuum cleaner 100 of the present invention is provided with two tapping portions, one or three or more tapping portions may be provided.

The vibration of the tapped portions 24a and 24b of the electric vacuum cleaner 100 according to the present invention is realized by a vibration motor (not shown) built in the head 1. The tapping portions 24a and 24b vibrate up and down with respect to the cleaning surface due to the vibration of the vibration motors provided in the tapping portions 24a and 24b, respectively. Further, the vibration motor may be surrounded by a cushioning material. By doing so, it is possible to prevent the noise of the vibration motor or the chattering noise generated by the head 1.

Further, motors having different rotation speeds of the vibration motors may be adopted, or control may be performed so that the vibration frequency changes randomly. By doing so, it is possible to prevent noise generated when the vibration frequency of the vibration motor coincides with the resonance frequency of the case.

The pile 26 is provided on the cleaning surface side of the head 1 and on the rear side of the suction port 12. The pile 26 is provided so as to be in contact with the cleaning surface. As a result, the airtightness around the suction port 12 can be improved and dust can be efficiently sucked. Further, since it is made of pile material, it is possible to prevent the cleaning surface from being damaged even if the head 1 is in contact with the cleaning surface.

The ultraviolet lamp 28 is provided at the rear portion of the head 1 on the cleaning surface side. The ultraviolet lamp 28 is attached to the inside of the head 1 and is covered with a cover.

It is provided on the right side of 28. The grounding sensors 30a and 30b are composed of a light emitting unit and a light receiving unit, and it is determined that the grounding sensor 30a and 30b are grounded by reflecting the light emitted from the light emitting unit on the ground surface and receiving the reflected light at the light receiving unit. On the contrary, when the light receiving portion cannot receive light, it is judged that the light is separated from the floor surface.

In the vacuum cleaner 100 according to the present invention, the ultraviolet lamp 28 is turned off when any of the grounding sensors 30a and 30b is separated from the cleaning surface. By this control, the ultraviolet rays from the ultraviolet lamp 28 are not directly seen by the eyes. Further, when both the grounding sensors 30a and 30b are separated from the cleaning surface, the ultraviolet lamp 28 is turned off and the electric vacuum cleaner 100 is put into an idling state. By this control, it is possible to suppress the power consumption of the vacuum cleaner 100 when the dust cannot be sucked.

The main body side wheel 32 is provided substantially in the center of the lower portion of the main body 2. The vacuum cleaner 100 can be smoothly moved by the front wheels 20a and 20b and the rear wheels 14.

The rotating portion 48 fits in the recess 50a of the receiving portion 50 and realizes a rotating operation.

A rotation restricting portion 52 is provided around the rotating portion 48. The rotation restricting portion 52 of the vacuum cleaner 100 according to the present invention includes a first convex portion 52a, a second convex portion 52b, and a third convex portion 52c. The distance between the first convex portion 52a and the second convex portion 52b is formed to be longer than the distance between the second convex portion 52b and the third convex portion 52c.

On the other hand, the receiving portion 50 is provided with the first flat plate portion 50b and the second flat plate 50c at intervals in the front-rear direction inside the recess 50a. Further, the first flat plate portion 50b and the second flat plate portion 50c are provided at positions where the convex portion of the rotation restricting portion 52 and the flat plate portions 50b and 50c come into contact with each other when the rotating portion 48 fits in the concave portion 50a. When the rotation restricting portion 52 comes into contact with the flat plate portions 50a and 50b, a frictional force is generated, and the rotation can be regulated.

Next, the state of the connection portion in each usage state will be described with reference to FIG. As shown in FIG. 9A, when the vacuum cleaner 100 is in the retracted state, the second convex portion 52b and the third convex portion 52c of the rotation restricting portion 52 are the first flat plate portion 50b and the second flat plate portion, respectively. It touches at the same time as 50c. Since the battery is built in the rear part of the vacuum cleaner 100 of the present invention, it is possible for the main body 2 to stand substantially vertically on the head 1 so that the main body 2 does not fall due to the weight of the battery in the stored state. ..

As shown in FIG. 9B, when the vacuum cleaner 100 is in the first use state, the first convex portion 52a of the rotation restricting portion 52 is in contact with the first flat plate portion 50b. By doing so, a frictional force is generated between the rotation restricting portion 52 and the flat plate portions 50b and 50c, and the rotation between the head 1 and the main body 2 can be restricted. At this time, since the length between the grip portion 38 and the head 1 is long in the front-rear direction, the vacuum cleaner 100 can easily reach a distant cleaning range.

As shown in FIG. 9C, when the vacuum cleaner 100 is in the second use state, the rotation restricting portion 52 does not come into contact with either the first flat plate portion 50b or the second flat plate portion 50c. With such a configuration, the angle formed by the head 1 and the main body 2 changes according to the positional relationship between the operator and the vacuum cleaner 100, so that the angle between the grip portion and the operator's hand does not become unnatural. ..

The first fixing portion 54 and the second fixing portion 56 are provided on the head 1 and the main body 2, respectively. In the vacuum cleaner 100 of the present invention, the first fixing portion 54 uses a magnet and the second fixing portion 56 uses a metal plate. When the vacuum cleaner 100 is in the first use state, it is provided at a position where the first fixing portion 54 and the second fixing portion 56 come into contact with each other. In the first use state, the first fixing portion 54 and the second fixing portion 56 come into contact with each other to maintain the contacted state by magnetic force. By providing the first fixing portion 54 and the second fixing portion 56, it is possible to regulate with a stronger force than the rotation regulation realized by the rotation restricting portion 52 and the flat plate portions 50b and 50c. Although a magnet and a metal plate are used in the present invention, they may be other than magnets as long as they have the same effect.

Further, the diffused portion 16b may be smoked or provided with irregularities.

A mounted light emitting means (not shown) is mounted on the sensor detection display unit board 16c. The light emitting means is a light emitting diode capable of emitting two colors of red and green in the vacuum cleaner 100 according to the present invention. It is possible to create multiple colors by mounting a light emitting diode that emits multiple colors and adjusting the brightness of each light emitting diode.

(Detailed configuration of the tapping part)
Next, the detailed configuration of the tapping portions 24a and 24b will be described with reference to FIGS. 13 and 14. Since the tapping portions 24a and 24b are configured as a pair on the left and right and have the same configuration, the tapping portion 24b will be described in detail.

The tapping portion 24b includes a tapping portion 24b for tapping the cleaning surface, a vibration motor 62 provided inside the head 1, and a vibration motor case 64 for accommodating the vibration motor 62. The vibration motor 62 generates vibration according to the rotation speed by rotating the weight 62b attached eccentrically to the rotation shaft 62a. The electric power for driving the vibration motor 62 is supplied from the outside by the wiring 62c. Therefore, the vibration motor case 64 is configured to be divisible, and the wiring 62c can be taken out of the vibration motor case 64.

The striking portion 24b and the vibration motor case 64 are screwed together by a screw 66, and the vibration of the vibration motor 62 vibrates the striking portion 24b transmitted to the vibration motor case 64. The tapping portion 24b and the vibration motor case 64 may be fixed by a fixing method other than screwing.

When the vibration motor 62 vibrates, the vibration motor 62 and the vibration motor case 64 collide with each other, and a so-called chattering noise is generated. To prevent this, each part is provided with a member that absorbs vibration.

The first vibration absorbing member 68 is provided in a through hole provided in the lower part of the head 1 for inserting the tapping portion 24b.

The tubular portions 28b and 28c guide the emitted light of the ultraviolet lamp 28 to the window portions 18a and 18b provided on the upper portion of the head 1. With this configuration, it is possible to confirm whether the ultraviolet lamp 28 is on or off through the windows 18a and 18b, so that it is not necessary to turn over the head 1 in order to confirm the operation of the ultraviolet lamp 28.

The wall portion 28d is provided on the reflector plate 28a so as to be in contact with the tubular portion 28c. A slit is provided in the wall portion 28d, and it is possible to fix the electric wiring.

The vacuum cleaner 100 according to the present invention has grounding sensors 30a and 30b that are turned off when the head 1 is lifted from the cleaning surface so that the emitted light of the ultraviolet lamp 28 does not directly enter the eyes. The grounding sensors 30a and 30b are composed of a light emitting element and a light receiving element. When the light emitted from the light emitting element is reflected on the cleaning surface and the light receiving element receives light, it is determined to be in the grounded state, and when the light receiving element does not receive light. Is determined to be away from the cleaning surface.

The grounding sensor 30a is arranged on the front left side of the ultraviolet lamp 28, and the grounding sensor 30b is arranged on the rear right side of the ultraviolet lamp 28. When either the grounding sensor 30a or 30b detects that the head 1 is separated from the cleaning surface, the ultraviolet lamp 28 is turned off.

The wiring for the grounding sensors 30a and 30b is drawn from the main body 2 through the opening of the rotating portion 48 and from the head 1. Of the wiring drawn out from the main body 2, the wiring is directly routed to the grounding sensor 30a. The wiring to the grounding sensor 30b is routed to the grounding sensor 30b through the upper part of the suction port 12 and the slit of the wall portion 28d. It is possible to prevent the wiring from inadvertently moving inside the head 1 by routing the wiring through the slit of the wall portion 28d.

In the vacuum cleaner 100 according to the present invention, in addition to the wall portion 28d described above as a wall portion for fixing wiring, the wall portions 80a and 80b provided on the suction port 12 and the wall portion provided on the outside of the vibration motor case 64. It has 80c and 80d. Like the wall portion 28d, slits for fixing wiring are formed in each of the wall portions 80a, 80b, 80c, and 80d.

FIG. 17 schematically shows the wiring inside the head 1. In the figure, the thick wire represents the wiring, and the wiring connected to the vibration motor 62 and the grounding sensor 30b on the right side is fixed to the wall portions 80a and 80b. By fixing at two places, a plurality of wirings can be routed together on the suction port 12 without being separated inside the head 1.

Wiring connected to the left and right vibration motors 62 is fixed to the wall portions 80c and 80d. Since the vibration motor 62 vibrates, the vibration is also transmitted to the wiring, but since it is fixed to the wall portions 80c and 80d, the wiring does not move more than necessary and the disconnection can be prevented.

The present invention is not limited to the above-described embodiment, and various changes, modifications, and the like can be made without changing the gist of the present invention.
