DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, a vacuum cleaner 1 according to one embodiment of the present invention will be described in detail with reference to the drawings. In the following description, the overall configuration of the vacuum cleaner 1 will be briefly described, and then the main parts will be described in more detail. In the following description, unless otherwise specified, the positional relationships in the up-down direction, width direction, front-rear direction, etc. will be described based on the state in which the vacuum cleaner 1 is erected as shown in FIG.

[0013] <Overall configuration of vacuum cleaner 1> As shown in Figs. 1 and 2, the vacuum cleaner 1 is a vacuum cleaner having a stick-shaped (vertical) appearance. The vacuum cleaner 1 can be, for example, a rechargeable type or a type that obtains power from an external power source via a power cord. As shown in Figs. 1 and 2, the vacuum cleaner 1 includes a vacuum cleaner body 10, a handle unit 20, a dust collection unit 50 (dust collection device), an extension tube 70, and a suction port body 100. Note that, in the following, an example will be described in which a stick-shaped (vertical) vacuum cleaner 1 includes the suction port body 100, but a so-called canister type vacuum cleaner may be configured to include the suction port body 100, or a handheld type vacuum cleaner may be configured to include the suction port body 100.

[0014] The vacuum cleaner main body 10 constitutes the main body of the vacuum cleaner 1 and is the part that exerts suction power to collect dust. Specifically, as shown in Fig. 2, the vacuum cleaner main body 10 includes, inside a housing 12 that forms a housing, an electric blower 14 for sucking in air and generating an airflow, a drive circuit for driving other electronic components, and other components.

[0015] The vacuum cleaner body 10 includes a battery storage section 15, and a battery 15a is stored in the battery storage section 15. The battery 15a (battery storage section 15) is provided in an area of ​​the vacuum cleaner body 10 that is rearward of the position where the handle section 20 is provided. The battery 15a is also provided in an area above the electric blower 14.

[0016] A main body suction port 32 for connecting the extension tube 70 or the suction port body 100 is provided at the lower end of the vacuum cleaner body 10. The vacuum cleaner body 10 has a main body tube section 30. The main body tube section 30 forms the main body suction port 32 at one end and also forms an outlet communicating with the inlet of the dust collection section 50. The main body suction port 32 is provided on the lower side in the vertical direction of the vacuum cleaner body 10. The battery storage section 15 is arranged to be aligned with the handle section 20 in a direction (front-rear direction) perpendicular to the axial direction (up-down direction) of the vacuum cleaner body 10.

[0017] The handle portion 20 is a portion provided for a user of the vacuum cleaner 1 to grip the vacuum cleaner body 10. The handle portion 20 may have any suitable shape, such as a circular shape, an oval shape such as an ellipse or an oval shape, a polygonal shape, or a rod shape. In this embodiment, the handle portion 20 is oval in shape. The handle portion 20 also forms a handle opening 22 for inserting a hand. The handle opening 22 is opened so that the length in the up-down direction is greater than the length in the front-rear direction. The vacuum cleaner 1 is configured so that the user can grip the vacuum cleaner body 10, for example, by passing the fingers except the thumb through the opening portion formed by the handle portion 20. The handle portion 20 is provided on the upper side of the vacuum cleaner body 10. The handle portion 20 is also located on the front side of the vacuum cleaner body 10. To explain the positional relationship between the handle portion 20 and the battery 15a in detail, the battery 15a is arranged so as to overlap within a range below the upper end of the handle opening 22 and above the lower end of the handle opening 22. Also, the external exhaust ports of the vacuum cleaner body 10 are arranged on both the left and right sides of the rear side.

[0018] The dust collecting section 50 is a section where dust sucked by the vacuum cleaner 1 is collected. As shown in FIG. 1 and FIG. 2, the dust collecting section 50 is provided so as to be continuous with the vacuum cleaner body 10. The dust collecting section 50 can be any suitable type, such as a so-called paper bag type or a so-called cyclone type dust collecting device. In this embodiment, the dust collecting section 50 is configured by a cyclone type dust collecting device. That is, the dust collecting section 50 is configured to collect dust in the process of introducing air from a dust collecting section inlet 58 provided in the outer cylinder 52, forming a swirling air current in the outer cylinder 52, and discharging the air. The dust collecting section 50 can adopt a so-called single-stage or multiple-stage separation type, but in this embodiment, a single-stage separation type is adopted. As shown in FIG. 2, the dust collecting section 50 has an outer cylinder 52 (dust cup) and a structure 54, and a dust collecting space 56 is formed between them.

[0019] The extension tube 70 is a cylindrical member that detachably connects the vacuum cleaner body 10 and the suction port body 100. One end of the extension tube 70 is shaped so that it can be inserted into the body suction port 32 provided in the body tube section 30 of the vacuum cleaner body 10, and the other end is shaped so that it can be connected to the suction port body 100. By connecting the vacuum cleaner body 10 and the suction port body 100 via the extension tube 70, a continuous communication path (air passage) from the suction port body 100 to the vacuum cleaner body 10 can be formed.

[0020] The suction port body 100 is connected directly to the main body suction port 32 of the vacuum cleaner main body 10, or indirectly via an extension tube 70. The suction port body 100 has a suction port 120 and a tube section 150. The suction port 120 opens toward the bottom. The tube section 150 is connectable to the main body suction port 32 or the extension tube 70. Characteristic parts of the suction port body 100 will be described in detail later.

[0021] The electric vacuum cleaner 1 is roughly configured as described above. The electric vacuum cleaner 1 has characteristic structures in the dust collecting section 50 and the suction port body 100. The suction port body 100 will be described in further detail below.

[0022] <About the suction port body 100> Next, the configuration of the suction port body 100 will be described in detail with reference to Figs. 3 to 12 and the like. The suction port body 100 is for taking in dust from the outside, and is capable of sucking in air and dust from the outside by the action of suction force from the electric blower 14. As shown in Figs. 3 and 4 and the like, the suction port body 100 has a case body 110 and a pipe section 150 (joint section). Furthermore, as shown in Figs. 6 and 7 and the like, the suction port body 100 has a rotating cleaning body 160, a drive section 170, and a power transmission mechanism 180 inside the case body 110. In addition to these configurations, the suction port body 100 has a light emitting unit 200.

[0023] The case body 110 is a part that is placed on the floor during cleaning, and has a shape that is long in the left-right direction compared to the front-rear direction in which the user operates during cleaning. As shown in FIG. 4 and other figures, the case body 110 includes a main body case 112 and a cover case 114, and the internal area formed by these includes an intake space 116, a storage section 118, a communication section 140, and the like. In addition to these, the case body 110 includes a light-emitting unit placement section 130 for mounting the light-emitting unit 200, which will be described later in detail. The case body 110 also includes a bumper 115 on the front side (front side) for mitigating impact when the case body 110 collides with another object such as a wall surface.

[0024] The main body case 112 is a member that constitutes the bottom part of the case body 110. The main body case 112 has the suction port 120 and is a member that constitutes the bottom part of the suction space 116 and the storage section 118. The suction port 120 is constituted by an opening formed in the main body case 112. The suction port 120 is an opening that is long in the width direction (left and right direction) of the main body case 112 (case body 110). The opening shape of the suction port 120 can be appropriately selected, but in this embodiment, it is rectangular. In addition, the main body case 112 has a curved portion 126. The curved portion 126 is a portion that covers an area corresponding to the suction space 116 in which the rotating cleaning body 160 is arranged, in the suction space 116 formed inside the case body 110.

[0025] The covering case 114 is a member provided so as to cover at least a portion of the above-mentioned main case 112. As shown in Figures 3 and 4, the covering case 114 has a first covering case component 122, a second covering case component 123, and a third covering case component 124.

[0026] The first covering case component 122 mainly constitutes a portion of the covering case 114 that is on one side in the left-right direction of the case body 110. In this embodiment, the first covering case component 122 covers an area adjacent to the left and right of the suction space 116 on the front side of the case body 110, an area corresponding to the storage section 118 formed inside the case body 110, and the like.

[0027] The second covering case component 123 is a part located on the central side in the left-right direction. The second covering case component 123 covers at least the light source 210 that constitutes the light emitting unit 200.

[0028] The third covering case component 124 is not an essential component, but forms a part of the covering case 114 on the other side in the left-right direction (the opposite side to the first covering case component 122).

[0029] As shown in Figs. 3, 4, 9, etc., curved portion 126 is a portion that is curved so as to be convex upward. The portion indicated by a black circle in the figures corresponds to apex T of the curved portion. Curved portion 126 is provided in suction space 116 formed inside case body 110 at a position that corresponds to suction space 116 where rotating cleaning body 160 is disposed. Curved portion 126 is formed so as to extend in the left-right direction (width direction) in case body 110. Curved portion 126 is formed so as to be curved in an arc shape when case body 110 is viewed from the side.

[0030] The suction space 116 communicates with the outside through the suction port 120 on the bottom side. Therefore, the suction space 116 can suck in dust and air from the suction port 120 and let them in. The suction space 116 extends in the left-right direction of the case body 110 and has a size that can accommodate the rotating cleaning body 160. The rotating cleaning body 160 is accommodated in the suction space 116 so as to be rotatable around the axis position. The suction space 116 communicates with a communication part 140 provided on the rear side of the suction space 116 at a middle part in the left-right direction (approximately the center part in the left-right direction in this embodiment). The communication part 140 has a communication port 140a at an end part (opposite the pipe part 150) that communicates with the suction space 116.

[0031] Similar to the suction space 116, the accommodation section 118 is a hollow space formed inside the case body 110 by combining the above-mentioned main body case 112 and covering case 114. The accommodation section 118 is provided at a position offset in the longitudinal direction from the suction space 116 or at a position on the rear side from the suction space 116. The accommodation section 118 accommodates the drive section 170, which will be described in detail later, the power transmission mechanism 180, the support section 190 (support section 190a), etc.

[0032] As shown in Fig. 4, Fig. 6, etc., the light emitting unit arrangement section 130 is a portion of the case body 110 where the light emitting unit 200, which will be described later in detail, is arranged. The light emitting unit arrangement section 130 is configured by a combination of a first covering case component 122, a second covering case component 123, and a third covering case component 124 that configure the covering case 114. Specifically, the covering case 114 is formed so that the first covering case component 122 and the third covering case component 124 do not overlap with the main case 112 in most parts. Meanwhile, the covering case 114 is attached such that the second covering case component 123 covers at least a part of the main case 112 in the portion that configures the light emitting unit arrangement section 130.

[0033] Here, in this embodiment, the light emitting unit 200 is disposed in the middle part (center part in the illustrated example) in the longitudinal direction (width direction) of the main body case 112. As shown in FIG. 4 and FIG. 5, etc., in response to this, the covering case 114 is provided with a bulging part 125 in which the second covering case constituent part 123 bulges in a direction away from the first covering case constituent part 122 at a position that is the longitudinal middle part of the case body 110. As a result, the covering case 114 is provided with a light emitting unit disposing part 130 for incorporating the light emitting unit 200 in the longitudinal (width direction) middle part between the first covering case constituent part 122 and the third covering case constituent part 124. Also, the bulging part 125 has a shape that is open toward the front side (front side).

[0034] Moreover, the covering case 114 is at least partially light-shielding. Specifically, at least the portion of the covering case 114 that forms the light-emitting unit arrangement portion 130 is light-shielding. In this embodiment, at least the portion of the first covering case component 122 that is covered by the bulging portion 125 (second covering case component 123) is light-shielding. Furthermore, at least the portion of the second covering case component 123 that forms the bulging portion 125 is light-shielding. Furthermore, the main body case 112 (case body 110) has at least a portion of a transmission portion 134 through which light from the light-emitting unit 200 (light source) passes. The light source of the light-emitting unit 200 is inclined so that the optical axis faces the bottom side, and when the optical axis passes through the main body case 112, it is preferable that the main body case 112 easily transmits light.

[0035] As shown in FIG. 10 and FIG. 11, the light-emitting unit arrangement section 130 has a base 132 therein. The base 132 is provided in the covering case 114 at a position rearward of the apex T of the curved portion 126. The base 132 functions as a base supporting the light-emitting unit 200, which will be described later in detail. When the case body 110 is viewed from the side, the base 132 can be formed, for example, by bulging a portion of the main case 112 rearward of the apex T of the curved portion 126 upward or by arranging a separately prepared member at that portion. In this embodiment, the base 132 is formed by bulging the main case 112. The base 132 is disposed at a position lower than the apex T of the curved portion 126.

[0036] As shown in FIG. 10 and FIG. 11, the light emitting unit arrangement section 130 is provided with a protrusion 130b formed of, for example, a screw or a pin on the base section 132. The protrusion 130b is provided so as to protrude upward from the suction space 116 side of the main body case 112 toward the upper side of the base section 132. The light emitting unit arrangement section 130 is provided with a convex boss section 130d having a recess 130c into which the protrusion 130b can be inserted, at a position corresponding to the protrusion 130b in the second covering case component 123. The case body 110 can be configured such that the main body case 112 and the second covering case component 123 are connected in the light emitting unit arrangement section 130 by a connecting structure formed by the protrusion 130b and the boss section 130d. The case body 110 can improve the positioning accuracy of the components constituting the light emitting unit 200 by assembling the components constituting the light emitting unit 200 based on the protrusion 130b.

[0037] As shown in FIG. 9 and other figures, the communication part 140 is a space formed inside the case body 110 so as to communicate with the above-mentioned suction space 116. The communication part 140 communicates with the suction space 116 at a middle part in the left-right direction (width direction) of the suction space 116. In this embodiment, the communication part 140 communicates with the suction space 116 at a substantially central part in the left-right direction of the suction space 116. The communication part 140 also communicates with the pipe part 150 via the communication opening 140a. Therefore, the communication part 140 functions as a space that communicates the suction space 116 and the pipe part 150. At least a part of the light-emitting unit 200 is located forward of the communication opening 140a.

[0038] The pipe section 150 is provided in a position of the case body 110 on the rear side (rear side) of the vacuum cleaner 1 so as to communicate with the communication section 140. The pipe section 150 is a portion (joint section) that functions as a joint to which the extension pipe 70 is connected. The pipe section 150 is attached to the case body 110 so as to be rotatable within a predetermined rotation range (at least one of the front-rear direction and the left-right direction). Specifically, the joint section to which the pipe section 150 is connected rotates left-right relative to the case body 110, and the pipe section 150 rotates front-rear relative to the joint section.

[0039] The rotary cleaning body 160 is a member accommodated in the suction space 116 and supported rotatably around a support shaft extending along the left-right direction (width direction) of the case body 110. Specifically, one end of the support shaft of the rotary cleaning body 160 is rotatably supported by a first support portion 190a of a support portion 190 described in detail later, and the other end is rotatably supported by a second support portion 190b. The rotary cleaning body 160 is rotatable in the suction space 116 by receiving power generated in the drive portion 170 via a power transmission mechanism 180 described in detail later. Thus, the rotary cleaning body 160 is supported rotatably relative to the case body 110.

[0040] The driving unit 170 serves as a driving source for the rotary cleaning body 160. The driving unit 170 is configured by an electric motor and is capable of outputting rotational power from an output shaft 170a. The driving unit 170 is accommodated in a space forming the accommodation section 118. Specifically, the driving unit 170 is accommodated in a space (accommodation section 118) provided at a position on the rear side of the suction space 116 and on one side in the left-right direction (width direction) of the communication section 140 in a state in which the suction port body 100 is viewed from above. The driving unit 170 is accommodated in a position in which the output shaft 170a protrudes approximately parallel to the rotation support shaft of the rotary cleaning body 160.

[0041] 4, 6, etc., the power transmission mechanism 180 is a mechanism for transmitting power between the rotary cleaning body 160 and the drive unit 170. The power transmission mechanism 180 is accommodated in a space (accommodating unit 118) that is provided at one side in the left-right direction (width direction) with respect to the suction space 116 when the suction port body 100 is viewed in a plan view, among the spaces that form the accommodation unit 118. The power transmission mechanism 180 includes an output pulley 182, a driven pulley 184, and a belt 186.

[0042] The output side pulley 182 is connected to the output shaft 170a of the drive unit 170 protruding toward the housing unit 118, and is a pulley that can rotate integrally with the output shaft 170a. The output side pulley 182 is configured by a toothed pulley that has teeth extending in the axial direction on its periphery. The output side pulley 182 is housed in the housing unit 118a in a rear area of ​​the case body 110 (suction port body 100).

[0043] The driven pulley 184 is a pulley directly or indirectly connected to the rotary cleaning body 160. The driven pulley 184 is rotatable integrally with the rotary cleaning body 160. The driven pulley 184 is configured by a toothed pulley having teeth extending in the axial direction on a periphery around which the belt 186 is wound. The driven pulley 184 is accommodated in the accommodation section 118 at a position adjacent to the suction space 116 in the left-right direction (width direction). Therefore, the driven pulley 184 is accommodated in the accommodation section 118a at a position away from the output pulley 182 on the front side of the case body 110 (suction port body 100).

[0044] The belt 186 is configured as an endless belt with teeth. The belt 186 is wound around an output pulley 182 and a driven pulley 184. The teeth on the belt 186 mesh with the teeth on the output pulley 182 and the driven pulley 184. Therefore, by operating the drive unit 170, the power transmission mechanism 180 can transmit the rotational power output from the output shaft 170a of the drive unit 170 to the rotary cleaning body 160 via the output pulley 182, the belt 186, and the driven pulley 184, thereby rotating the rotary cleaning body 160.

[0045] The support part 190 rotatably supports the rotating cleaning body 160 inside the case body 110. Specifically, the support part 190 has a first support part 190a that supports the rotating cleaning body 160 on one axial side, and a second support part 190b that supports the rotating cleaning body 160 on the other axial side. The first support part 190a and the second support part 190b each have a bearing, and thus can rotatably support the spindle of the rotating cleaning body 160. The third covering case component 124 has a part that covers the second support part 190b of the main body case 112, but from the viewpoint of weight reduction, it is not necessary to provide a part that covers the second support part 190b.

[0046] The light-emitting unit 200 is intended to emit light toward the front side of the case body 110 to illuminate an area in front of the case body 110. As shown in Fig. 6 and Figs. 8 to 12, the light-emitting unit 200 is assembled to a light-emitting unit mounting portion 130 provided in the case body 110. The light-emitting unit 200 includes, as components, a light source 210, a substrate 220, a cover 230, a guide portion 250, and a fixture 260.

[0047] The light source 210 emits light when electricity is applied, such as an LED or a light bulb. In this embodiment, an LED is provided as the light source 210. The light source 210 is mounted on the front surface side of the substrate 220. The light source 210 is arranged on the base 132 with its optical axis facing forward (front side). In this embodiment, the substrate 220 on which the light source 210 is mounted is arranged so that the light source 210 faces forward, and the substrate 220 is erected on the base 132 behind the protrusion 130b, so that the light source 210 is arranged on the base 132. In addition, the light source 210 may be provided as a single light source or as a plurality of light sources, three or more, but in this embodiment, two light sources are provided. The light sources 210, 210 are arranged at a predetermined interval in the longitudinal direction (left-right direction) of the case body 110. In addition, the light sources 210, 210 are arranged symmetrically with the longitudinal center of the case body 110 as a boundary.

[0048] 10, 11, etc., the substrate 220 has the light source 210 attached to its front surface as described above, and is provided with the connector 222 on its back surface. The substrate 220 has an engaged portion 224 at a position that is the upper end side when the substrate 220 is placed upright on the base portion 132. The engaged portion 224 is a portion that engages with the guide portion 250. The engaged portion 224 may have any shape or structure as long as it can engage with the guide portion 250, but in this embodiment it is configured by a rectangular cutout.

[0049] As shown in FIG. 11, the light source 210 is mounted on the substrate 220 as described above and is disposed in the light emitting unit disposing section 130. As a result, the light source 210 is disposed so as to irradiate light to the front side of the case body 110 through the opening 130a. The light source 210 is disposed between the main body case 112 and the covering case 114 in the light emitting unit disposing section 130. The light source 210 is disposed at a position above the suction space 116. The light source 210 is located on the front side with respect to the tube section 150. The light source 210 is disposed in the base section 132, and is therefore located rearward of the apex of the curved shape section 126. The light source 210 is disposed in an inclined position so that the optical axis approaches the bottom surface side.

[0050] The cover 230 is capable of transmitting light from the light source 210. Specifically, as shown in Figs. 10 to 12 and the like, the cover 230 includes a light emitting portion 232, a base connecting portion 234, and a boss engaging portion 240.

[0051] The light emitting portion 232 is formed in a plate shape that closes the opening 130a of the light emitting unit arrangement portion 130. The light emitting portion 232 is capable of transmitting light emitted from the light source 210. In this embodiment, the light emitting portion 232 is formed of a transparent plate.

[0052] The base connection part 234 is a part that is connected to the base part 132. The base connection part 234 has a protrusion engagement part 236 and a base engagement part 238. The base connection part 234 has a hook-like shape that is bent into an L-shape in a side view by the protrusion engagement part 236 and the base engagement part 238.

[0053] The protrusion engagement portion 236 is connected to the light emitting portion 232 at its base end, and is a plate-like portion extending in a direction intersecting the light emitting portion 232. The protrusion engagement portion 236 extends rearward from the light emitting portion 232 inside the light emitting unit arrangement portion 130 when the light emitting unit 200 is in an assembled state. The protrusion engagement portion 236 is provided with an insertion hole 236a through which the protrusion 130b provided on the base portion 132 can be inserted. The base engagement portion 238 is a plate-like portion extending in a direction intersecting the protrusion engagement portion 236 on the tip side of the protrusion engagement portion 236 (the rear side when the light emitting unit 200 is in an assembled state).

[0054] The boss engagement portion 240 is a portion that engages with the boss portion 130d provided on the top surface side (the bulging portion 125 of the second covering case constituent portion 123) of the light-emitting unit arrangement portion 130. The boss engagement portion 240 is provided at a position spaced upward from the protrusion engagement portion 236 of the base connection portion 234 described above. Like the protrusion engagement portion 236, the boss engagement portion 240 is connected to the light emitting portion 232 at its base end, and is a plate-like portion that extends in a direction intersecting the light emitting portion 232 (rearward). The boss engagement portion 240 is provided with a boss engagement hole 242 large enough to insert the boss portion 130d therethrough.

[0055] The cover 230 includes the base connection portion 234 and the boss engagement portion 240 on the back side (rear side) of the light emission portion 232. The base engagement portion 238 is bent downward with respect to the protrusion engagement portion 236 at a position away from the connection position (base end of the protrusion engagement portion 236) between the protrusion engagement portion 236 and the light emission portion 232 by an amount equivalent to the length of the base portion 132 in the front-rear direction from the connection position (base end of the protrusion engagement portion 236). Therefore, as shown in FIG. 8, FIG. 12, etc., the base connection portion 234 is attached so that the protrusion engagement portion 236 covers the base portion 132 from above, and the base engagement portion 238 is engaged with the rear side of the base portion 132. As a result, the base connection portion 234 is positioned in the front-rear direction with respect to the base portion 132. Further, the protrusion 130b provided on the base portion 132 is inserted into the insertion hole 236a provided on the protrusion engagement portion 236. Furthermore, the boss engagement portion 240 has the boss portion 130d protruding downward from the top surface side of the light-emitting unit arrangement portion 130 inserted into the boss engagement hole 242. Furthermore, the protrusion 130b protruding upward from the bottom is inserted into the recess 130c provided on the boss portion 130d through the insertion hole 236a of the protrusion engagement portion 236, and is in an engaged state. As a result, the base connection portion 234 and the boss engagement portion 240 are positioned in the front-rear direction and the left-right direction (width direction). The base connection portion 234 is attached to the base portion 132 in this manner. Therefore, the light emitting portion 232 is installed in a state where it is positioned in any of the front, rear, left and right directions by the connection structure formed by the base connecting portion 234, the boss engaging portion 240, the base portion 132, and the protrusion 130b.

[0056] The guide portion 250 is provided to guide the light generated in the light source 210 to the cover 230. As shown in Figs. 6, 8, etc., and as shown in Figs. 10 to 12, etc., the guide portion 250 is fixed to the case body 110 in a state where it is sandwiched between the substrate 220 and the cover 230. The guide portion 250 is fixed in a state where it is engaged with the substrate 220. The guide portion 250 includes a light guiding portion 252 and an engagement portion 256.

[0057] The light guide 252 functions as a light guide member that guides the light generated in the light source 210 toward the cover. The light guide 252 has a cylindrical shape with openings at one end and the other end. This allows the light guide 252 to guide the light introduced from the opening at one end toward the other end and emit it from the opening at the other end. The light guide 252 also has a light blocking property. This allows the light guide 252 to suppress leakage of light to the outside before the light introduced from one end reaches the other end. Therefore, the light guide 252 can guide substantially all of the light generated in the light source 210 from one end to the other end.

[0058] Moreover, the light guiding section 252 has a length equivalent to the distance between the substrate 220 and the cover 230 that are arranged to face each other in the front-rear direction when the light emitting unit 200 is incorporated in the light emitting unit arrangement section 130. Therefore, by arranging the light guiding section 252 between the substrate 220 and the cover 230, the light guiding section 252 can be arranged such that one end side of the light guiding section 252 is in contact with the front surface of the substrate 220 and the other end side of the light guiding section 252 is in contact with the rear surface side (rear surface) of the cover 230. Therefore, the light guiding section 252 can suppress the leakage of light from both the substrate 220 side that serves as the light inlet and the cover 230 side that serves as the light outlet.

[0059] The light guide 252 is provided corresponding to the light source 210. As described above, in this embodiment, the two light sources 210, 210 are arranged with a predetermined interval therebetween. Therefore, in this embodiment, the two light guides 252, 252 are provided with an equal interval therebetween to the light sources 210, 210. In this embodiment, the light guides 252, 252 are arranged in parallel so that an interval corresponding to the width (length in the left-right direction) of the base 132 is formed between the light guides 252, 252. The light guides 252, 252 are connected by a light guide connector 254 on the side that serves as the light inlet. The light guide connector 254 may have any shape as long as it can connect the light guides 252, 252, but in this embodiment, it is a plate-shaped one.

[0060] The engaging portion 256 is for engaging the guide portion 250 with the substrate 220. As described above, since the engaged portion 224 is provided at the upper end portion of the substrate 220, the engaging portion 256 is adapted to engage with the engaged portion 224. Specifically, the engaging portion 256 is configured as a piece that extends from the light-guiding connection portion 254 toward the substrate 220 and engages with the engaged portion 224 in a state in which the light-emitting unit 200 is assembled in the light-emitting unit arrangement portion 130.

[0061] The engaging portion 256 has a piece-shaped portion 256a that is inserted from the front side to the rear side into a rectangular cutout that forms the engaged portion 224, and an engaging protrusion 256b that protrudes from the tip side of the piece-shaped portion 256a in a direction intersecting the extension direction of the piece-shaped portion 256a. In this embodiment, the engaging portion 256 has the engaging protrusions 256b, 256b protruding on both the left and right sides of the piece-shaped portion 256a. Therefore, the engaging portion 256 can engage the guide portion 250 with the substrate 220 by an engagement structure formed by inserting the piece-shaped portion 256a from the front side to the back side of the substrate 220 in the engaged portion 224 and engaging the engaging protrusions 256b, 256b on the back side of the substrate 220.

[0062] The guide section 250 is configured by connecting the light guide sections 252, 252 by the light guide connection section 254 on the side that serves as the light inlet. The light guide connection section 254 is configured to be plate-shaped. The light guide connection section 254 is arranged so as to be in surface contact with the surface of the substrate 220 in a state in which the light-emitting unit 200 is assembled to the light-emitting unit arrangement section 130. In this embodiment, the light guide connection section 254 is arranged so as to be in surface contact with the surface of the substrate 220 in a state in which it is sandwiched in a gap between the substrate 220 that is erected in the vertical direction and the back surface of the base section 132 that is formed so as to extend in the vertical direction. Furthermore, the guide section 250 can be engaged with the substrate 220 by engaging the engagement section 256 with the engaged section 224 of the substrate 220 as described above. Therefore, the guide section 250 is arranged in a state of being positioned in the light-emitting unit arrangement section 130 based on the substrate 220 and the light guide connection section 254 that is arranged in surface contact therewith as references. Furthermore, in a state where the light-emitting unit 200 is incorporated into the light-emitting unit mounting section 130, the base connection section 234 and the boss engagement section 240 of the cover 230 are disposed between the light-guiding sections 252, 252. As a result, the guide section 250 and the cover 230 are disposed in the light-emitting unit mounting section 130 in a state where they are also positioned relative to each other by the base connection section 234 and the boss engagement section 240.

[0063] The fixture 260 is attached to the main body case 112 and the covering case 114 in the light-emitting unit arrangement section 130, thereby fixing the cover 230. The fixture 260 is configured by a combination of the protrusion 130b and the boss section 130d described above. The fixture 260 can fix the cover 230 while positioning it by inserting a pin or screw forming the protrusion 130b into an insertion hole 236a provided in the protrusion engagement section 236 of the cover 230. The fixture 260 can also fix the cover 230 while positioning it by inserting the boss section 130d into the boss engagement hole 242 provided in the boss engagement section 240 of the cover 230 and engaging the protrusion 130b with the recess 130c.

[0064] <About the effects, etc.> The effects and the like obtained by the above-mentioned suction mouth unit 100 and the electric vacuum cleaner 1 equipped with the same will be described below.

[0065] [Regarding the suction mouth body 100 and the electric vacuum cleaner 1 according to the first aspect of the present invention] Conventionally, a floor suction tool for an electric vacuum cleaner has been provided, as disclosed in a patent document (JP Patent Publication 2010-148661 A). This floor suction tool has a suction port on the bottom surface of a main body case, and a rotating brush rotated by a drive source is disposed inside the main body case facing the suction port. In addition, this floor suction tool has a lighting unit on the top surface of the main body case that illuminates the front. The floor suction tool of the vacuum cleaner according to the above-mentioned patent document is structured with a flip-up shutter, and an illumination unit is provided at the top of the curved, upwardly convex shape of the main body case. With such a configuration, there is a problem that the illumination unit protrudes from the top, which hinders the miniaturization of the floor suction tool. Therefore, an object of the present invention is to provide a suction port body for a vacuum cleaner that can be made compact in a configuration that includes a light source, and a vacuum cleaner that includes the suction port body. (1-1) The suction port body 100 of the vacuum cleaner 1 has a curved portion 126 that is curved so as to be convex upward, and comprises a case body 110 having a suction port 120 on the bottom surface, a tube portion 150 that connects the suction source and the suction port 120 rearward of the curved portion 126, and a light source 210 arranged to irradiate light to the front side of the case body 110, characterized in that the light source 210 is located forward of the tube portion 150 and rearward of the top of the curved portion 126.

[0066] In the suction port body 100 of the above-mentioned vacuum cleaner 1, the light source 210 is provided at a position behind the curved portion 126 that is curved so as to be convex upward in the case body 110 and in front of the tube portion 150 that is located behind the curved portion 126. This allows the suction port body 100 to provide the light source 210 by utilizing the space between the curved portion 126 and the tube portion 150. Therefore, according to the suction port body 100 of the above-mentioned embodiment, it is possible to provide the light source 210 while achieving miniaturization, compared to the conventional technology in which the light source 210 is provided so as to protrude from the top of the curved portion 126 or the conventional technology in which the light source 210 is provided in front of the curved portion 126.

[0067] (1-2) As described above, the suction port body 100 of the vacuum cleaner 1 relating to (1-1) is characterized in that the case body 110 has the suction port 120 and includes a main case 112 that defines the suction space 116, and a covering case 114 that covers at least a portion of the main case 112, and the light source 210 is arranged between the main case 112 and the covering case 114.

[0068] By configuring suction port body 100 as described above in (1-2), light source 210 can be provided without being exposed to the outside of main body case 112 and covering case 114 that constitute case body 110. This allows suction port body 100 to have light source 210 orderly arranged without being exposed to the outside.

[0069] (1-3) As described above, the suction port body 100 of the vacuum cleaner 1 relating to (1-1) or (1-2) may be characterized in that it includes the suction space 116 and a communication portion 140 that communicates with the tube portion 150 rearward of the suction space 116, and that the light source 210 is disposed above the suction space 116.

[0070] By configuring suction port body 100 as described above in (1-3), it is possible to utilize the space provided above suction space 116 located forward of communication portion 140 to place light source 210.

[0071] (1-4) As described above, the suction port body 100 of the vacuum cleaner 1 relating to any one of (1-1) to (1-3) is preferably characterized in that the case body 110 has a base portion 132 rearward of the apex of the curved portion 126, and the light-emitting unit 200 including the light source 210 is disposed on the base portion 132, so that the optical axis of the light source 210 is inclined so as to approach the bottom side.

[0072] By configuring suction port body 100 as described above in (1-4), light source 210 can be arranged rearward of the apex of curved portion 126, while allowing light source 210 to generate light from a position higher by the height of base portion 132. Furthermore, in suction port body 100, light source 210 is arranged such that the optical axis is inclined toward the bottom side. Therefore, suction port body 100 can irradiate light generated in light source 210 toward the bottom side.

[0073] (1-5) As described above, the suction port body 100 of the vacuum cleaner 1 relating to any one of (1-1) to (1-4) is preferably characterized in that the case body 110 has a base portion 132 rearward of the apex of the curved portion 126, and the base portion 132 is disposed at a position lower than the apex.

[0074] By configuring the suction port body 100 as described above in (1-5), it is possible to position the light source 210 as low as possible below the curved portion 126, while more reliably irradiating the light generated by the light source 210 toward the front side.

[0075] (1-6) As described above, the suction mouth body 100 of the vacuum cleaner 1 relating to any of (1-1) to (1-5) may include a light-emitting unit 200 having a cover 230 that transmits light from the light source 210, and a guide portion 250 that guides the light from the light source 210 to the cover 230, and is characterized in that the light-emitting unit 200 is fixed to the case body 110 with the guide portion 250 sandwiched between the substrate 220 on which the light source 210 is arranged, and the cover 230.

[0076] By configuring suction port body 100 as described above in (1-6), guiding section 250 can reliably cause light generated in light source 210 to reach cover 230. As a result, suction port body 100 can reliably emit light generated in light source 210 from cover 230. Furthermore, suction port body 100 is installed in a state in which guiding section 250 is sandwiched and positioned between substrate 220 and cover 230. Therefore, suction port body 100 can reliably guide light generated in light source 210 to cover 230.

[0077] (1-7) As described above, the suction mouth body 100 of the vacuum cleaner 1 according to any one of (1-1) to (1-6) may be as described in claim 5, characterized in that the guide portion 250 and the base plate 220 are fixed by an engagement structure.

[0078] By configuring suction port body 100 as described above in (1-7), guiding section 250 can be positioned with reference to substrate 220. Therefore, suction port body 100 has high positioning accuracy between light source 210 arranged on substrate 220 and guiding section 250. As a result, suction port body 100 can reliably guide light generated by light source 210 with guiding section 250.

[0079] (1-8) As described above, the suction port body 100 of the electric vacuum cleaner 1 relating to any one of (1-1) to (1-7) preferably includes a rotating cleaning body 160 rotatably arranged in the suction space 116, a drive unit 170 which serves as a drive source for the rotating cleaning body 160, and a power transmission mechanism 180 which transmits a driving force from the drive unit 170 to the rotating cleaning body 160, and the covering case 114 is characterized in that it covers the power transmission mechanism 180.

[0080] By configuring the suction port body 100 as described above in (1-8), the light source 210 can be provided by utilizing the covering case 114 that covers the power transmission mechanism 180.

[0081] (1-9) As described above, the suction port body 100 of the vacuum cleaner 1 relating to any one of (1-1) to (1-8) is preferably characterized in that a part of the case body 110 has a light-transmitting portion 134 having translucency, and light from the light source 210 transmits through the light-transmitting portion 134.

[0082] By configuring suction port body 100 as described above in (1-9), light generated by light source 210 can be transmitted through transmitting portion 134 of case body 110, thereby illuminating the front.

[0083] (1-10) The electric vacuum cleaner 1 includes the suction mouth body 100 according to any one of (1-1) to (1-9) described above.

[0084] Since the electric vacuum cleaner 1 includes the suction port body 100 described above, the suction port body 100 can have a compact configuration while still providing the light source 210 in the suction port body 100.

[0085] [Regarding the suction mouth body 100 and the vacuum cleaner 1 according to the second aspect of the present invention] Here, the floor suction tool of the vacuum cleaner disclosed in JP 2010-148661 A is provided with an illumination unit that illuminates the area ahead. This floor suction tool is based on a structure that has a flip-up shutter, and the illumination unit is provided above the main body case.

[0086] Here, the suction port body of the floor suction tool of the conventional technology described above is a part that is easily subjected to external impacts when carrying or cleaning, and there is a concern that such impacts may cause the lighting section to become loose or shift out of place.

[0087] Therefore, an object of the present invention is to realize an intake body with a light-emitting unit that has improved impact resistance.

[0088] (2-1) The suction port body 100 of the vacuum cleaner 1 comprises a case body 110 having a suction port 120 on the bottom surface, a tube section 150 connecting the suction source and the suction port 120, and a light-emitting unit 200 arranged to irradiate light to the front side of the case body 110, and is characterized in that the light-emitting unit 200 is fixed to the case body 110.

[0089] By configuring the suction port body 100 as described above in (2-1), even if it receives an external impact when carrying or cleaning it, the light emitting unit is unlikely to come off or cause other problems. Therefore, by configuring the suction port body 100 as described above in (2-1), it is possible to realize a suction port body 100 with a light emitting unit 200 that has improved impact resistance.

[0090] In the suction port body 100 according to the second aspect of the present invention, the case body 110 is not limited to a configuration having a curved portion 126 that is convex upward, and includes, for example, a configuration in which the upper surface of the case body 110 (main body case 112) is flat, or a configuration in which the case body 110 has an upper surface that becomes lower from the rear side to the front side. In the case of a configuration in which the case body 110 (main body case 112) has an upper surface that becomes lower from the rear side to the front side, if the drive unit 170 is provided diagonally above the rotating cleaning body 160, the front-to-rear length of the rotating cleaning body 160 and the drive unit 170 can be shortened compared to a configuration in which the drive unit 170 is located directly behind the rotating cleaning body 160, and it becomes easier to tilt the optical axis of the light source 210 diagonally downward.

[0091] (2-2) As described above, in the suction port body 100 of the vacuum cleaner 1 relating to (2-1), the light-emitting unit 200 has a light source 210, a cover 230 that transmits light from the light source 210, and a guide portion 250 that guides the light from the light source 210 to the cover 230, and it is preferable that the light-emitting unit 200 is fixed to the case body 110 with the guide portion 250 sandwiched between the substrate 220 on which the light source 210 is arranged and the cover 230.

[0092] By configuring suction port body 100 as described above in (2-2), guide section 250 for guiding light generated by light source 210 is positioned by being sandwiched between substrate 220 and cover 230. As a result, even if suction port body 100 is subjected to an external shock when being carried or cleaned, problems such as guide section 250 becoming displaced or guide section 250 falling off are unlikely to occur. Therefore, by configuring suction port body 100 as described above in (2-2), it is possible to further improve the shock resistance.

[0093] Furthermore, the suction port body 100 can reliably guide the light generated by the light source 210 to the cover 230. This makes it possible for the suction port body 100 to suppress the occurrence of poor light emission in the cover 230 due to the guide portion 250 falling off or being misaligned.

[0094] (2-3) As described above, the suction head body 100 of the vacuum cleaner 1 according to (2-1) or (2-2) may be characterized in that the guide portion 250 and the base plate 220 are fixed together by an engagement structure.

[0095] By configuring suction port body 100 as described above in (2-3), it is possible to arrange substrate 220 and guide portion 250 in a state where they are positioned relative to each other. This makes it possible for suction port body 100 to have high impact resistance, in which displacement of substrate 220 and guide portion 250 is unlikely to occur even if suction port body 100 is subjected to an external impact when being carried or cleaned.

[0096] (2-4) As described above, the suction port body 100 of the vacuum cleaner 1 relating to any of (2-1) to (2-3) preferably includes a case body 110 having the suction port 120, a main case 112 that defines the suction space 116, and a covering case 114 that covers at least a portion of the main case 112, and the cover 230 or the guide portion 250 (the cover 230 in the above embodiment) has an insertion hole 236a, and the fixing device 260 (protrusion 130b) is fixed to the covering case 114 from the main case 112 through the insertion hole 236a.

[0097] By configuring suction port body 100 as described above in (2-4), it is possible to position cover 230 and guide section 250 using insertion hole 236a as a reference. This allows suction port body 100 to have high impact resistance, in which displacement of substrate 220 and guide section 250 is unlikely to occur even if suction port body 100 is subjected to an external impact. Note that, in the above embodiment, a configuration in which insertion hole 236a for inserting protrusion 130b forming fixture 260 is provided in cover 230 has been exemplified, but the present invention is not limited to this, and it is also possible for something equivalent to insertion hole 236a to be provided in guide section 250.

[0098] (2-5) As described above, the suction port body 100 of the vacuum cleaner 1 relating to any of (2-1) to (2-4) is preferably characterized in that a part of the case body 110 has a light-transmitting portion 134 having translucency, and light from the light-emitting unit 200 transmits through the light-transmitting portion 134.

[0099] By configuring suction port body 100 as described above in (2-5), light generated by light source 210 can be irradiated toward the front of case body 110 via transmission portion 134 that case body 110 has.

[0100] (2-6) The vacuum cleaner 1 includes the suction mouth body 100 according to any one of (2-1) to (2-5) described above.

[0101] By configuring the vacuum cleaner 1 as described above in (2-6), it is possible to provide the vacuum cleaner 1 with high impact resistance and the suction mouth body 100 equipped with the light emitting unit 200.

[0102] In the suction port body 100 according to the first aspect of the present invention, the case body 110 is configured to have a curved portion 126 that is convex upward, but it is also possible to configure the drive unit 170 to be provided diagonally above the rear side of the rotating cleaning body 160, and to configure the case body 110 (main case 112) so that its upper surface becomes lower from the rear side to the front side.

[0103] (3-1) In other words, in order to solve the same problems as those of the first embodiment described above, the suction port body 100 of the third aspect of the present invention comprises a case body 110 having an upper surface which becomes lower from the rear side to the front side and having a suction port 120 on the front bottom surface, a tube section 150 which connects the suction source and the suction port 120, a light source 210 arranged to irradiate light to the front side of the case body 110, a rotating cleaning body 160 arranged rotatably in the case body 110, a drive unit 170A which serves as a drive source for the rotating cleaning body 160, and a power transmission mechanism which transmits a driving force from the drive unit 170A to the rotating cleaning body, and the drive unit 170A is arranged diagonally above the rear side of the rotating cleaning body 160. This allows the front-to-rear length of the rotating cleaning body 160 and the drive unit 170A to be shorter compared to a configuration in which the drive unit 170 is located directly behind the rotating cleaning body 160, making it possible to reduce the size of the suction port body 100 while making it easier to tilt the optical axis of the light source 210 diagonally downward.

[0104] (3-2) In addition, the above (3-1) may have at least one of the above (1-2) to (1-3) and (1-6) to (1-9).

[0105] <<Variations>> The examples given in the above embodiment are merely examples of the present invention, and the configurations according to (1-1) to (1-10) and (2-1) to (2-6) may be different from those given in the above embodiment, without departing from the spirit of the present invention. The suction mouth body and vacuum cleaner of the present invention may be provided with other configurations in addition to or in place of the configurations included in (1-1) to (1-10) and (2-1) to (2-6), or may be configured with some of the configurations omitted. Specifically, the following modified examples are possible.

[0106] In the above embodiment, the light guiding section 252 of the guide section 250 has a passage that extends linearly from one end side to the other end side, but the present invention is not limited to this. The guide section 250 may have a curved light passage that extends from one end side of the light guiding section 252 to the other end side.

[0107] In the above-described embodiment, the configuration in which the cover 230 is fixed to the case body 110 has been exemplified, but the present invention is not limited to this. The guide portion 250 or the substrate 220 may be fixed to the case body 110.

[0108] In the above-described embodiment, the guide portion 250 and the substrate 220 are fixed to each other by forming an engagement structure, but the present invention is not limited to this. For example, the suction port body 100 may be configured such that the guide portion 250 is fixed to the substrate 220 by using screws, adhesive, or the like.

[0109] The present invention is not limited to the above-mentioned embodiments and modifications, and other embodiments may be possible within the scope of the claims. The components of the above-mentioned embodiments may be arbitrarily selected and combined. Any component of the embodiment may be arbitrarily combined with any component described in the means for solving the problems or any component that embodies any component described in the means for solving the problems. We intend to obtain rights to these as well through amendments to this application or divisional applications, etc. [Industrial Applicability]
