[0005] Therefore, an object of the present invention is to realize a suction inlet body with a light-emitting unit having improved impact resistance.
Means for Solving the Problems
[0006] The suction inlet body of the present invention provided to solve the above-described problems includes a case body having a suction inlet on the bottom surface, a pipe portion that communicates the suction source and the suction inlet, and a light-emitting unit arranged to irradiate light on the front side of the case body, and the light-emitting unit is fixed to the case body. The light-emitting unit comprises a light source, a cover that transmits light from the light source, and a guide portion that guides the light from the light source to the cover, and the case body comprises a main body case having the intake port and constituting an intake space, and a covering case that covers at least a part of the main body case, and the cover or the guide portion has an insertion hole, and the fixing device is fixed from the main body case through the insertion hole to the covering case.
[0007] The suction port body of the present invention, with the above-described configuration, is less prone to malfunctions such as the light-emitting unit becoming detached due to external impacts during transport or cleaning. Therefore, by adopting the above-described configuration, a suction port body with a light-emitting unit that has improved impact resistance can be realized.
[0008] The electric vacuum cleaner of the present invention is equipped with a suction port body according to the present invention.

[0012] Hereinafter, an electric 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 electric vacuum cleaner 1 will be described in general terms, and then the main parts will be described in more detail. In the following description, unless otherwise specified, positional relationships in the vertical, horizontal, and front-to-back directions will be described based on the state in which the electric vacuum cleaner 1 is erected, as shown in Figure 1.
[0013] ≪Overall Configuration of Vacuum Cleaner 1≫ As shown in Fig. 1, Fig. 2, etc., 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 one that obtains power from an external power source via a power cord. As shown in Fig. 1 and Fig. 2, the vacuum cleaner 1 includes a cleaner main body 10, a handle portion 20, a dust collection portion 50 (dust collection device), an extension pipe 70, and a suction inlet body 100. In the following, the case where the stick-shaped (vertical) vacuum cleaner 1 includes the suction inlet body 100 will be described as an example, but a so-called canister-type vacuum cleaner may have a configuration including the suction inlet body 100, or a handy-type vacuum cleaner may have a configuration including the suction inlet body 100.
[0014] The cleaner main body 10 forms the main body of the vacuum cleaner 1 and is a part that exhibits the function of generating a suction force for dust collection. Specifically, as shown in Fig. 2, inside the housing 12 that forms the housing of the cleaner main body 10, there are provided an electric blower 14 for sucking air to generate an air flow, a drive circuit for driving other electronic components, and other components.
[0015] The cleaner main body 10 includes a battery housing portion 15, and a battery 15a is housed in the battery housing portion 15. The battery 15a (battery housing portion 15) is provided in a region on the rear side of the cleaner main body 10 relative to the position where the handle portion 20 is provided. Also, the battery 15a is provided in an upper region with respect to the electric blower 14.
[0016] On the lower end side of the cleaner main body 10, a main body suction port 32 for connecting the extension pipe 70 or the suction inlet body 100 is provided. The cleaner main body 10 has a main body pipe portion 30. The main body pipe portion 30 forms a main body suction port 32 at one end and a discharge port that communicates with the inlet of the dust collection portion 50. The main body suction port 32 is provided on the lower side in the vertical direction of the cleaner main body 10. The battery housing portion 15 is arranged in a direction (front-rear direction) orthogonal to the axial direction (vertical direction) of the cleaner main body 10 so as to be aligned with the handle portion 20.
[0017] The handle portion 20 is a part provided for the user of the vacuum cleaner 1 to grip the vacuum cleaner body 10. The handle portion 20 can have any suitable shape, such as a circular shape, an oval shape such as an ellipse or oblong 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 its length in the vertical direction is greater than its length in the front-to-back direction. The vacuum cleaner 1 is configured so that the user can grip the vacuum cleaner body 10 by, for example, inserting their fingers (excluding the thumb) into the opening 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 in detail the positional relationship between the handle 20 and the battery 15a, the battery 15a is positioned 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. In addition, the external exhaust ports of the vacuum cleaner body 10 are located on both the left and right sides of the rear.
[0018] The dust collection section 50 is the part where dust and debris sucked up by the vacuum cleaner 1 are collected. As shown in Figures 1 and 2, the dust collection section 50 is provided so as to be continuous with the vacuum cleaner body 10. The dust collection section 50 can be a so-called paper bag type or a so-called cyclone type dust collection device, or any other appropriate type. In this embodiment, the dust collection section 50 is configured as a cyclone type dust collection device. That is, the dust collection section 50 is configured to collect dust in the process of introducing air from a dust collection section inlet 58 provided in the outer cylinder 52, forming a swirling airflow within the outer cylinder 52, and then discharging the air. The dust collection section 50 can employ a so-called single-stage or multi-stage separation method, but in this embodiment, a single-stage separation method is employed. As shown in Figure 2, the dust collection section 50 has an outer cylinder 52 (dust cup) and a structure 54, with a dust collection space 56 formed between them.
[0019] The extension tube 70 is a cylindrical member that detachably connects the vacuum cleaner body 10 and the suction port 100. One end of the extension tube 70 is shaped to be inserted into the main suction port 32 provided in the main pipe section 30 of the vacuum cleaner body 10, and the other end is shaped to be connected to the suction port 100. By connecting the vacuum cleaner body 10 and the suction port 100 via the extension tube 70, a series of connected paths (air passages) from the suction port 100 to the vacuum cleaner body 10 can be formed.
[0020] The suction port body 100 is connected directly to the main suction port 32 of the vacuum cleaner body 10, or indirectly via the extension pipe 70. The suction port body 100 has a suction port 120 and a pipe section 150. The suction port 120 opens toward the bottom. The pipe section 150 can be connected to the main suction port 32 or the extension pipe 70. Characteristic parts of the suction port body 100 will be described in detail later.
[0021] The vacuum cleaner 1 is generally configured as described above. The vacuum cleaner 1 is said to have a distinctive structure in the dust collection unit 50 and the suction port 100. The suction port 100 will be described in more detail below.
[0022] Regarding the suction port body 100: Next, the configuration of the suction port body 100 will be explained in detail with reference to Figures 3 to 12, etc. The suction port body 100 is for taking in dust from the outside, and the suction force from the electric blower 14 allows it to suck in air and dust from the outside. As shown in Figures 3 and 4, the suction port body 100 has a case body 110 and a pipe section 150 (joint section). In addition, as shown in Figures 6 and 7, the suction port body 100 has a rotating cleaning body 160, a drive unit 170, and a power transmission mechanism 180 inside the case body 110. In addition to these components, the suction port body 100 has a light-emitting unit 200.
[0023] The case body 110 is the part that is placed on the floor during cleaning and has a shape that is elongated in the left-right direction relative to the front-back direction, which is the direction in which the user moves during cleaning. As shown in Figure 4, the case body 110 comprises a main body case 112 and a covering case 114, and the internal area formed by these comprises a suction space 116, a housing section 118, and a communication section 140. In addition to these, the case body 110 also has a light-emitting unit placement section 130 for assembling the light-emitting unit 200, which will be described in detail later. Furthermore, the case body 110 is equipped with a bumper 115 on the front side (front side) to mitigate the impact when it collides with other objects such as walls.
[0024] The main body case 112 is a component that constitutes the bottom portion of the case body 110. The main body case 112 has a suction port 120 and is a component that forms the bottom portion of the suction space 116 and the housing section 118. The suction port 120 is formed 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-right direction) of the main body case 112 (case body 110). The shape of the opening of the suction port 120 can be any appropriate shape, but in this embodiment it is rectangular. The main body case 112 also has a curved portion 126. The curved portion 126 is a portion that covers the area of the suction space 116 formed inside the case body 110 that corresponds to the suction space 116 in which the rotating cleaning body 160 is placed.
[0025] The covering case 114 is a component provided to cover at least a part of the main body case 112 described above. 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 forms one side of the case body 110 in the left-right direction within the covering case 114. In this embodiment, the first covering case component 122 covers the areas adjacent to the suction space 116 on the left-right side of the front of the case body 110, and the area corresponding to the housing portion 118 formed inside the case body 110.
[0027] The second covering case component 123 is 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 it forms the other side of the covering case 114 in the left-right direction (opposite side of the first covering case component 122).
[0029] As shown in Figures 3, 4, and 9, the curved portion 126 is a part that is curved so as to be convex upward. In the figures, the part indicated by the black circle corresponds to the apex T of the curved portion. The curved portion 126 is provided in the suction space 116 formed inside the case body 110, at a position corresponding to the suction space 116 where the rotating cleaning body 160 is placed. The curved portion 126 is formed to extend in the left-right direction (width direction) of the case body 110. The curved portion 126 is formed to curve in an arc shape when the case body 110 is viewed from the side.
[0030] The suction space 116 communicates with the outside via the suction port 120 on its bottom side. Therefore, dust and air can be drawn into the suction space 116 through the suction port 120. The suction space 116 extends in the left-right direction of the case body 110 and is large enough to accommodate the rotating cleaning body 160. The rotating cleaning body 160 is housed in the suction space 116 so as to be rotatable about its axial position. The suction space 116 communicates with a communication section 140 located on the rear side of the suction space 116 at its intermediate point in the left-right direction (approximately the center in this embodiment). The end of the communication section 140 (opposite the pipe section 150) has a communication port 140a that communicates with the suction space 116.
[0031] The housing section 118, like the suction space 116, is a hollow space formed inside the case body 110 by combining the main body case 112 and the covering case 114 described above. The housing section 118 is located at a position offset longitudinally from the suction space 116, or at a position rearward from the suction space 116. The housing section 118 houses the drive unit 170, the power transmission mechanism 180, the support unit 190 (support unit 190a), etc., which will be described in detail later.
[0032] As shown in Figures 4 and 6, the light-emitting unit arrangement section 130 is the part of the case body 110 where the light-emitting unit 200, which will be described in detail later, is arranged. The light-emitting unit arrangement section 130 is composed of a combination of the first covering case component 122, the second covering case component 123, and the third covering case component 124 that constitute 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 body case 112 in most respects. On the other hand, in the part of the covering case 114 that forms the light-emitting unit arrangement section 130, the second covering case component 123 is attached so that it covers at least a part of the main body case 112.
[0033] In this embodiment, the light-emitting unit 200 is positioned in the middle of the longitudinal direction (width direction) of the main body case 112 (the central part in the illustrated example). As shown in Figures 4 and 5, the covering case 114 is configured such that the second covering case component 123 has a bulge 125 that bulges away from the first covering case component 122 at a position that is the middle of the longitudinal direction of the case body 110. As a result, the covering case 114 has a light-emitting unit placement section 130 for incorporating the light-emitting unit 200 between the first covering case component 122 and the third covering case component 124, located in the middle of the longitudinal direction (width direction). Furthermore, the bulge 125 has a shape that is open toward the front side (front side).
[0034] Furthermore, the covering case 114 is designed to have light-shielding properties in at least a portion of it. Specifically, the covering case 114 is designed to have light-shielding properties in at least the portion that forms the light-emitting unit arrangement portion 130. In this embodiment, the first covering case component 122 is designed to have light-shielding properties in at least the portion that is covered by the bulging portion 125 (second covering case component 123). Also, the second covering case component 123 is designed to have light-shielding properties in at least the portion that forms the bulging portion 125. In addition, the main body case 112 (case body 110) has at least a portion of a transmissive portion 134 through which light from the light-emitting unit 200 (light source) is transmitted. The light source of the light-emitting unit 200 is tilted so that the optical axis faces the bottom side, but when the optical axis passes through the main body case 112, it is preferable that the main body case 112 transmits light easily.
[0035] As shown in Figures 10 and 11, the light-emitting unit placement section 130 has a base section 132 inside. The base section 132 is provided in the covering case 114 at a position behind the top T of the curved section 126. The base section 132 functions as a base that supports the light-emitting unit 200, which will be described in detail later. When the case body 110 is viewed from the side, the base section 132 can be formed, for example, by bulging upward the part of the main case 112 that is behind the top T of the curved section 126, or by placing a separately prepared member in that part. In this embodiment, the base section 132 is formed by bulging the main case 112. The base section 132 is positioned lower than the top T of the curved section 126.
[0036] As shown in Figures 10 and 11, the light-emitting unit arrangement section 130 is provided with a base section 132 having a protrusion 130b, such as a screw or pin. The protrusion 130b is provided so as to project upward from the suction space 116 side of the main body case 112 toward the base section 132. Furthermore, the light-emitting unit arrangement section 130 is provided with a convex boss section 130d in the second covering case component 123 at a position corresponding to the protrusion 130b, which has a recess 130c into which the protrusion 130b can be inserted. 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 composed of the protrusion 130b and the boss section 130d. In addition, 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 with the protrusion 130b as a reference.
[0037] As shown in Figure 9, the communication section 140 is a space formed inside the case body 110 to communicate with the suction space 116 described above. The communication section 140 communicates with the suction space 116 at the middle of the suction space 116 in the left-right direction (width direction). In this embodiment, the communication section 140 communicates with the suction space 116 at approximately the center of the suction space 116 in the left-right direction. The communication section 140 also communicates with the pipe section 150 via the communication port 140a. Therefore, the communication section 140 functions as a space that connects the suction space 116 and the pipe section 150. At least a part of the light-emitting unit 200 is located in front of the communication port 140a.
[0038] The pipe section 150 is provided in a position on the rear side (rear side) of the case body 110, so as to communicate with the communication section 140. The pipe section 150 is a part (joint section) that functions as a joint to which the extension pipe 70 is connected. The pipe section 150 is mounted on the case body 110 so as to be rotatable within a predetermined range of rotation (at least one of the front-to-back direction and the left-to-right direction). Specifically, the joint section to which the pipe section 150 is connected rotates left-to-right relative to the case body 110, and the pipe section 150 rotates front-to-back relative to the joint section.
[0039] The rotating cleaning body 160 is housed in the suction space 116 described above and is a member that is rotatably supported with respect to a pivot shaft that extends along the left-right direction (width direction) of the case body 110 as the center of rotation. Specifically, one end of the pivot shaft of the rotating cleaning body 160 is rotatably supported by the first support part 190a of the support part 190, which will be described in detail later, and the other end is rotatably supported by the second support part 190b. Furthermore, the rotating cleaning body 160 is made rotatable in the suction space 116 by receiving power generated in the drive unit 170 via the power transmission mechanism 180, which will be described in detail later. As a result, the rotating cleaning body 160 is rotatably supported with respect to the case body 110.
[0040] The drive unit 170 is the power source for the rotating cleaning body 160. The drive unit 170 is composed of an electric motor and is capable of outputting rotational power from its output shaft 170a. The drive unit 170 is housed in a space that forms the housing section 118. Specifically, the drive unit 170 is housed in a space (housing section 118) that is located on the rear side of the suction space 116 and on one side of the communication section 140 in the left-right direction (width direction) when the suction port body 100 is viewed from above. The drive unit 170 is housed in a position where its output shaft 170a protrudes approximately parallel to the rotation support shaft of the rotating cleaning body 160.
[0041] As shown in Figures 4 and 6, the power transmission mechanism 180 is a mechanism for transmitting power between the rotating cleaning body 160 and the drive unit 170. The power transmission mechanism 180 is housed in a space (housing section 118) that is located on one side in the left-right direction (width direction) relative to the suction space 116 when the suction port body 100 is viewed from above. The power transmission mechanism 180 includes an output pulley 182, a driven pulley 184, and a belt 186.
[0042] The output pulley 182 is connected to the output shaft 170a of the drive unit 170, which protrudes toward the housing 118, and is a pulley that can rotate integrally with the output shaft 170a. The output pulley 182 is composed of a toothed pulley with teeth extending axially on its circumference. The output pulley 182 is housed in the rear region of the case body 110 (suction port body 100) in the housing 118a.
[0043] The driven pulley 184 is a pulley directly or indirectly connected to the rotating cleaning body 160. The driven pulley 184 is designed to rotate integrally with the rotating cleaning body 160. The driven pulley 184 is composed of a toothed pulley with teeth extending axially on the circumference over which the belt 186 is placed. The driven pulley 184 is housed in the housing section 118 in a position adjacent to the suction space 116 in the left-right direction (width direction). Therefore, in the housing section 118a, the driven pulley 184 is housed in a position away from the output pulley 182 on the front side of the case body 110 (suction port body 100).
[0044] Belt 186 is made of a toothed endless belt. Belt 186 is wrapped between the output pulley 182 and the driven pulley 184. The teeth on 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 transmits the rotational power output from the output shaft 170a of the drive unit 170 to the rotating cleaning body 160 via the output pulley 182, belt 186, and driven pulley 184, thereby rotating the rotating cleaning body 160.
[0045] The support portion 190 rotatably supports the rotating cleaning body 160 inside the case body 110. Specifically, the support portion 190 has a first support portion 190a that supports the rotating cleaning body 160 on one side in the axial direction, and a second support portion 190b that supports it on the other side in the axial direction. The first support portion 190a and the second support portion 190b are each equipped with bearings, thereby enabling the pivot shaft of the rotating cleaning body 160 to be rotatably supported. The third covering case component 124 has a portion that covers the second support portion 190b of the main case 112, but from the viewpoint of weight reduction, it is not necessary to provide a portion that covers the second support portion 190b.
[0046] The light-emitting unit 200 emits light toward the front of the case body 110, thereby illuminating the front area of the case body 110. As shown in Figures 6 and 8 to 12, the light-emitting unit 200 is assembled to a light-emitting unit placement section 130 provided on the case body 110. The light-emitting unit 200 comprises a light source 210, a substrate 220, a cover 230, a guide section 250, and a fixing device 260 as its components.
[0047] The light source 210 is a device that emits light when power 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 surface side of the substrate 220. The light source 210 is positioned so that its optical axis faces forward (front side) and is placed on the base portion 132. In this embodiment, the light source 210 is positioned on the base portion 132 by placing the substrate 220 on which the light source 210 is mounted so that the light source 210 faces forward, and the substrate 220 is erected on the base portion 132 behind the protrusion 130b. In addition, there may be only one light source 210 or three or more, but in this embodiment, two 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. Furthermore, the light sources 210, 210 are arranged symmetrically with respect to the longitudinal center of the case body 110 as the boundary.
[0048] As shown in Figures 10 and 11, the substrate 220 has the light source 210 mounted on its front surface and a connector 222 on its back surface, as described above. The substrate 220 has an engaging portion 224 at the upper end when it is erected on the base portion 132. The engaging portion 224 is the part that engages with the guide portion 250. The engaging portion 224 may have any shape or structure as long as it is able to engage with the guide portion 250, but in this embodiment it is composed of a rectangular notch.
[0049] As shown in Figure 11, the light source 210 is mounted on the substrate 220 as described above and placed in the light-emitting unit placement section 130. This arrangement allows the light source 210 to irradiate the front side of the case body 110 through the opening 130a. The light source 210 is also positioned between the main body case 112 and the covering case 114 in the light-emitting unit placement section 130. Furthermore, the light source 210 is positioned above the intake space 116. The light source 210 is located in front of the tube section 150. Because the light source 210 is placed in the base section 132, it is located behind the top of the curved section 126. The light source 210 is positioned in an inclined position so that its optical axis approaches the bottom surface.
[0050] The cover 230 is designed to allow light from the light source 210 to pass through. Specifically, as shown in Figures 10 to 12, the cover 230 is equipped with a light emitting section 232, a base connection section 234, and a boss engagement section 240.
[0051] The light-emitting section 232 is formed in the shape of a plate that closes the opening 130a of the light-emitting unit arrangement section 130. The light-emitting section 232 is designed to transmit light emitted from the light source 210. In this embodiment, the light-emitting section 232 is formed of a transparent plate.
[0052] The base connection portion 234 is the part that connects to the base portion 132. The base connection portion 234 has a protruding engagement portion 236 and a base engagement portion 238. The base connection portion 234 has a hook-like shape that is bent in an L-shape when viewed from the side due to the protruding engagement portion 236 and the base engagement portion 238.
[0053] The projection engagement portion 236 is a plate-shaped portion that is connected to the light-emitting portion 232 at its base end and extends in a direction intersecting the light-emitting portion 232. In the assembled state of the light-emitting unit 200, the projection engagement portion 236 extends rearward from the light-emitting portion 232 inside the light-emitting unit arrangement portion 130. The projection engagement portion 236 is provided with an insertion hole 236a through which the projection 130b provided in the base portion 132 can be inserted. The base engagement portion 238 is a plate-shaped portion that extends in a direction intersecting the projection engagement portion 236 at the tip side of the projection engagement portion 236 (rear side in the assembled state of the light-emitting unit 200).
[0054] The boss engagement portion 240 is the part that engages with the boss portion 130d provided on the top surface side of the light-emitting unit arrangement portion 130 (the bulging portion 125 of the second covering case component 123). The boss engagement portion 240 is provided at a position above and away from the protruding engagement portion 236 of the base connection portion 234 described above. Similar to the protruding engagement portion 236, the boss engagement portion 240 is connected to the light-emitting portion 232 at its base end and is a plate-shaped 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 that is sized to allow the boss portion 130d to pass through.
[0055] The cover 230 is equipped with the base connection portion 234 and boss engagement portion 240 on the back (rear side) of the light emitting portion 232 described above. Furthermore, the base engagement portion 238 is bent downward relative to the protruding engagement portion 236 at a position corresponding to the length of the base portion 132 in the front-rear direction from the connection position between the protruding engagement portion 236 and the light emitting portion 232 (the base end of the protruding engagement portion 236). Therefore, as shown in Figures 8 and 12, the base connection portion 234 is attached so that the protruding engagement portion 236 covers the base portion 132 from above, thereby engaging the base engagement portion 238 on the rear side of the base portion 132. As a result, the base connection portion 234 is positioned in the front-rear direction relative to the base portion 132. Furthermore, the projection 130b provided on the base portion 132 is inserted through the insertion hole 236a provided on the projection engagement portion 236. In addition, the boss engagement portion 240 is inserted through the boss engagement hole 242 into the boss engagement hole 242 into the boss portion 130d, which is projecting downward from the top surface of the light-emitting unit arrangement portion 130. Furthermore, the projection 130b projecting upward from below is inserted into the recess 130c provided on the boss portion 130d via the insertion hole 236a of the projection engagement portion 236, thereby engaging them. 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 section 232 is installed in a position that can be positioned in any direction, front, back, left, or right, by a connection structure consisting of a base connection section 234, a boss engagement section 240, a base section 132, and a projection 130b.
[0056] The guide portion 250 is provided to guide the light generated by the light source 210 to the cover 230. As shown in Figures 6 and 8, and as shown in Figures 10 to 12, the guide portion 250 is fixed to the case body 110 while sandwiched between the substrate 220 and the cover 230. The guide portion 250 is also fixed in an engaged state with the substrate 220. The guide portion 250 includes a light guide portion 252 and an engagement portion 256.
[0057] The light guide section 252 functions as a light guide member that guides the light generated in the light source 210 toward the cover. The light guide section 252 has a cylindrical shape with openings at one end and the other end. As a result, the light guide section 252 guides the light introduced from the opening at one end toward the other end and emits it from the opening at the other end. In addition, the light guide section 252 is designed to have light-shielding properties. As a result, the light guide section 252 can suppress light leakage to the outside between the light introduced from one end and the other end. Therefore, the light guide section 252 can guide almost all of the light generated in the light source 210 from one end to the other end.
[0058] Furthermore, the light guide section 252 has a length corresponding to the distance between the substrate 220 and the cover 230, which are arranged facing each other in the front-to-back direction when the light-emitting unit 200 is assembled into the light-emitting unit arrangement section 130. Therefore, by arranging the light guide section 252 between the substrate 220 and the cover 230, the light guide section 252 can be positioned such that one end of the light guide section 252 is in contact with the surface of the substrate 220, while the other end of the light guide section 252 is in contact with the back side (rear side) of the cover 230. As a result, the light guide section 252 can suppress light leakage on both the substrate 220 side, which is the light inlet, and the cover 230 side, which is the light outlet.
[0059] The light guide section 252 is provided in correspondence with the light source 210. As described above, in this embodiment, the two light sources 210, 210 are arranged at a predetermined distance apart. Therefore, in this embodiment, the two light guide sections 252, 252 are provided at the same distance apart as the light sources 210, 210. In this embodiment, the light guide sections 252, 252 are arranged in parallel such that a gap equivalent to the width (length in the left-right direction) of the base section 132 is formed between them. The light guide sections 252, 252 are connected by a light guide connector 254 on the side that serves as the light inlet. The shape of the light guide connector 254 can be made appropriate as long as it can connect to the light guide sections 252, 252, but in this embodiment it is plate-shaped.
[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 of the substrate 220, the engaging portion 256 is designed to engage with the engaged portion 224. Specifically, the engaging portion 256 is composed of a piece-shaped element that extends from the light guide connection portion 254 toward the substrate 220 and engages with the engaged portion 224 when the light-emitting unit 200 is assembled to the light-emitting unit placement portion 130.
[0061] The engaging portion 256 has a flap-shaped portion 256a that is inserted from the front to the rear in a rectangular notch forming the engaged portion 224, and an engaging projection 256b that protrudes from the tip side of the flap-shaped portion 256a in a direction intersecting the extension direction of the flap-shaped portion 256a. In this embodiment, the engaging portion 256 has engaging projections 256b, 256b protruding from both the left and right sides relative to the flap-shaped portion 256a. Therefore, the engaging portion 256 can be engaged with the substrate 220 by an engaging structure formed by inserting the flap-shaped portion 256a from the front side to the back side of the substrate 220 in the engaged portion 224, and engaging the engaging projections 256b, 256b on the back side of the substrate 220.
[0062] The guide section 250 is configured such that the light guide sections 252, 252 are connected by a light guide connector 254 on the side that serves as the light inlet. The light guide connector 254 is plate-shaped. The light guide connector 254 is positioned so as to be in surface contact with the surface of the substrate 220 when the light-emitting unit 200 is assembled to the light-emitting unit placement section 130. In this embodiment, the light guide connector 254 is positioned so as to be in surface contact with the surface of the substrate 220, sandwiched in the gap between the vertically erect substrate 220 and the back surface of the base section 132 which is formed to extend vertically. Furthermore, the guide section 250 can be engaged with the substrate 220 by engaging the engaging section 256 with the engaged section 224 of the substrate 220 as described above. Therefore, the guide section 250 is positioned within the light-emitting unit placement section 130 with respect to the substrate 220 and the light guide connector 254 which is in surface contact with it. Furthermore, when the light-emitting unit 200 is assembled into the light-emitting unit placement section 130, the base connection section 234 and boss engagement section 240 of the cover 230 are positioned between the light guide sections 252, 252. As a result, the guide section 250 and the cover 230 are positioned relative to each other by the base connection section 234 and boss engagement section 240 when placed in the light-emitting unit placement section 130.
[0063] The fixing device 260 is attached to the main body case 112 and the covering case 114 in the light-emitting unit placement section 130 to fix the cover 230. The fixing device 260 is composed of the above-described combination of protrusion 130b and boss portion 130d. The fixing device 260 can position and fix the cover 230 by inserting a pin or screw forming the protrusion 130b into the insertion hole 236a provided in the protrusion engagement portion 236 of the cover 230. In addition, the fixing device 260 can position and fix the cover 230 by inserting the boss portion 130d into the boss engagement hole 242 provided in the boss engagement portion 240 of the cover 230 and engaging the protrusion 130b into the recess 130c.
[0064] Regarding the effects and benefits: The following describes the effects obtained by the suction port 100 described above and the vacuum cleaner 1 equipped therewith.
[0065] [Regarding the suction port 100 and vacuum cleaner 1 according to the first aspect of the present invention] Conventionally, floor vacuum cleaner attachments have been provided, such as the one disclosed in the patent document (Japanese Patent Publication No. 2010-148661). This floor vacuum cleaner has a suction port on the bottom of the main body case, and a rotating brush, driven by a power source, is positioned inside the main body case facing the suction port. In addition, this floor vacuum cleaner has an illumination unit that lights up the front on the top surface of the main body case. The floor suction attachment for the electric vacuum cleaner described in the aforementioned patent document has a structure equipped with a flip-up shutter, and the main body case has a curved top that protrudes upwards, with a lighting unit provided at the top. With this configuration, the protrusion of the lighting unit from the top hinders the miniaturization of the floor suction attachment. Therefore, the present invention aims to realize a vacuum cleaner suction port that can be miniaturized in a configuration that includes a light source, and a vacuum cleaner equipped with said suction port. (1-1) The suction port body 100 of the electric vacuum cleaner 1 comprises a case body 110 having a curved portion 126 that is curved upward so as to be convex upward and a suction port 120 on its bottom surface, a pipe portion 150 that connects the suction source and the suction port 120 behind the curved portion 126, and a light source 210 that is positioned to irradiate light to the front of the case body 110, wherein the light source 210 is positioned in front of the pipe portion 150 and behind the top of the curved portion 126.
[0066] In the suction port body 100 of the electric vacuum cleaner 1 described above, the light source 210 is provided at a position behind the curved portion 126 that curves upward in the case body 110, and in front of the pipe portion 150 which is located behind the curved portion 126. As a result, the suction port body 100 can utilize the space between the curved portion 126 and the pipe portion 150 to provide the light source 210. Therefore, the suction port body 100 of the above embodiment makes it possible to achieve miniaturization while providing a light source 210, 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 in the case where 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 electric vacuum cleaner 1 according to (1-1) is characterized in that the case body 110 includes a main body case 112 having a suction port 120 and constituting a suction space 116, and a covering case 114 covering at least a part of the main body case 112, and the light source 210 is disposed between the main body case 112 and the covering case 114.
[0068] By configuring the suction port body 100 as described in (1-2) above, the light source 210 can be provided without being exposed to the outside of the main body case 112 and the covering case 114 that make up the case body 110. As a result, the suction port body 100 can be made in which the light source 210 is neatly arranged without being exposed to the outside.
[0069] (1-3) As described above, the suction port body 100 of the electric vacuum cleaner 1 according to (1-1) or (1-2) is preferably characterized by comprising a suction space 116 and a connecting portion 140 that connects the pipe portion 150 behind the suction space 116, and a light source 210 being positioned above the suction space 116.
[0070] By configuring the suction port body 100 as described in (1-3) above, the light source 210 can be positioned by utilizing the space provided above the suction space 116 located in front of the communication section 140.
[0071] (1-4) As described above, the suction port body 100 of the electric vacuum cleaner 1 according to any of (1-1) to (1-3) is characterized in that the case body 110 has a base portion 132 behind the top of the curved portion 126, and the light-emitting unit 200 including the light source 210 is arranged on the base portion 132 so that the optical axis of the light source 210 is tilted toward the bottom surface.
[0072] By configuring the intake port 100 as described in (1-4) above, the light source 210 is positioned behind the top of the curved section 126, while still allowing light to be generated from the light source 210 at a higher position due to the base section 132. Furthermore, the light source 210 in the intake port 100 is positioned so that its optical axis is inclined toward the bottom surface. Therefore, the intake port 100 can irradiate the light generated by the light source 210 toward the bottom surface.
[0073] (1-5) As described above, the suction port body 100 of the electric vacuum cleaner 1 according to any of (1-1) to (1-4) is preferably characterized in that the case body 110 has a base portion 132 behind the top of the curved portion 126, and the base portion 132 is positioned lower than the top.
[0074] By configuring the intake port 100 as described in (1-5) above, it becomes possible to position the light source 210 as low as possible below the curved section 126, while more reliably directing the light generated by the light source 210 towards the front.
[0075] (1-6) As described above, the suction port body 100 of the vacuum cleaner 1 according to any of (1-1) to (1-5) is characterized in that it comprises a light-emitting unit 200 having a cover 230 that transmits light from a light source 210 and a guide portion 250 that guides the light from the light source 210 to the cover 230, and 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] The intake port 100, with the configuration described in (1-6) above, can reliably guide the light generated in the light source 210 to the cover 230 via the guide portion 250. This ensures that the intake port 100 can reliably emit the light generated in the light source 210 from the cover 230. Furthermore, in the intake port 100, the guide portion 250 is positioned by being sandwiched between the substrate 220 and the cover 230. Therefore, the intake port 100 can reliably guide the light generated in the light source 210 to the cover 230.
[0077] (1-7) As described above, the suction port body 100 of the vacuum cleaner 1 relating to any of (1-1) to (1-6) is preferably the one 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 the intake port body 100 as described in (1-7) above, the guide portion 250 can be positioned relative to the substrate 220. Therefore, the intake port body 100 has high positional accuracy between the light source 210 placed on the substrate 220 and the guide portion 250. As a result, the intake port body 100 can reliably guide the light generated by the light source 210 with the guide portion 250.
[0079] (1-8) As described above, the suction port body 100 of the electric vacuum cleaner 1 according to any of (1-1) to (1-7) comprises a rotating cleaning body 160 rotatably disposed in the suction space 116, a drive unit 170 that is the driving source for the rotating cleaning body 160, and a power transmission mechanism 180 that transmits driving force from the drive unit 170 to the rotating cleaning body 160, and the covering case 114 covers the power transmission mechanism 180.
[0080] By configuring the suction port body 100 as described in (1-8) above, 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 electric vacuum cleaner 1 according to any of (1-1) to (1-8) is characterized in that a part of the case body 110 has a light-transmitting portion 134, and light from the light source 210 passes through the light-transmitting portion 134.
[0082] By configuring the intake port body 100 as described in (1-9) above, the light generated by the light source 210 is transmitted through the transparent portion 134 of the case body 110, thereby illuminating the area in front.
[0083] (1-10) The electric vacuum cleaner 1 is equipped with a suction port body 100 relating to any of (1-1) to (1-9) described above.
[0084] Since the electric vacuum cleaner 1 is equipped with the suction port body 100 described above, the suction port body 100 can be made compact while still having a light source 210.
[0085] [Regarding the suction port 100 and vacuum cleaner 1 according to a second aspect of the present invention] Here, the floor vacuum cleaner suction attachment disclosed in Japanese Patent Publication No. 2010-148661 is equipped with a lighting unit that illuminates the front. This floor vacuum cleaner is based on a structure having a flip-up shutter, and the lighting unit is provided at the top of the main body case.
[0086] Here, the suction port of the conventional floor suction device described above is a part that is easily subjected to external impacts when being carried or cleaned, and there are concerns that such impacts may cause the lighting unit to become detached or shift in position.
[0087] Therefore, the present invention aims to realize an intake port body with a light-emitting unit that has improved impact resistance.
[0088] (2-1) The suction port body 100 of the electric vacuum cleaner 1 comprises a case body 110 having a suction port 120 on its bottom surface, a pipe 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, wherein the light-emitting unit 200 is fixed to the case body 110.
[0089] By configuring the suction port body 100 as described in (2-1) above, even if it is subjected to external impact during transport or cleaning, malfunctions such as the light-emitting unit coming off due to such impact are less likely to occur. Therefore, by configuring it as described in (2-1) above, a suction port body 100 with a light-emitting unit 200 that has improved impact resistance can be realized.
[0090] Furthermore, the suction port body 100 according to the second aspect of the present invention is not limited to a configuration in which the case body 110 has a curved shape portion 126 that is convex upward, but also 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 slopes downward from the rear to the front. In the case where the case body 110 (main body case 112) has an upper surface that slopes downward from the rear to the front, if the drive unit 170 is provided on the upper diagonal rear side of the rotating cleaning body 160, the front-to-back 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 the optical axis of the light source 210 can be tilted diagonally downward.
[0091] (2-2) As described above, the suction port body 100 of the electric vacuum cleaner 1 according to (2-1) preferably has a light-emitting unit 200 having 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, with the guide portion 250 sandwiched between the substrate 220 on which the light source 210 is arranged and the cover 230, and the light-emitting unit 200 fixed to the case body 110.
[0092] By configuring the suction port body 100 as described in (2-2) above, the guide portion 250 for guiding the light generated by the light source 210 is positioned by being sandwiched between the substrate 220 and the cover 230. As a result, even if the suction port body 100 is subjected to external impacts during transport or cleaning, malfunctions such as the guide portion 250 becoming misaligned or falling off are less likely to occur. Therefore, by configuring the suction port body 100 as described in (2-2) above, the impact resistance can be further improved.
[0093] Furthermore, the intake port 100 can reliably guide the light generated by the light source 210 to the cover 230. This prevents the intake port 100 from causing luminescence failure in the cover 230 due to the detachment or misalignment of the guide portion 250.
[0094] (2-3) As described above, the suction port body 100 of the vacuum cleaner 1 according to (2-1) or (2-2) is preferably characterized in that the guide portion 250 and the base plate 220 are fixed by an engagement structure.
[0095] By configuring the suction port body 100 as described in (2-3) above, the substrate 220 and the guide portion 250 can be positioned relative to each other. As a result, the suction port body 100 can be made highly impact-resistant, so that the substrate 220 and the guide portion 250 are less likely to shift position even if they are subjected to external impacts during transport or cleaning.
[0096] (2-4) As described above, the suction port body 100 of the vacuum cleaner 1 according to any of (2-1) to (2-3) is preferably such that the case body 110 includes a main body case 112 having a suction port 120 and constituting a suction space 116, and a covering case 114 covering at least a part of the main body case 112, and the cover 230 or guide portion 250 (cover 230 in the above embodiment) has an insertion hole 236a, and the fixing device 260 (projection 130b) is fixed from the main body case 112 through the insertion hole 236a to the covering case 114.
[0097] By configuring the suction port body 100 as described in (2-4) above, the cover 230 and guide portion 250 can be positioned with respect to the insertion hole 236a. As a result, the suction port body 100 can be made highly impact-resistant, so that even if it is subjected to external impact, displacement of the substrate 220 and guide portion 250 is less likely to occur. In the above embodiment, a configuration in which the insertion hole 236a for inserting the protrusion 130b forming the fixing device 260 is provided in the cover 230 is illustrated, but the present invention is not limited to this, and it is also possible to provide something equivalent to the insertion hole 236a in the guide portion 250.
[0098] (2-5) As described above, the suction port body 100 of the vacuum cleaner 1 according to any of (2-1) to (2-4) is characterized in that a part of the case body 110 has a light-transmitting portion 134, and light from the light-emitting unit 200 is transmitted through the light-transmitting portion 134.
[0099] By configuring the intake port 100 as described in (2-5) above, the light generated in the light source 210 can be directed forward of the case body 110 through the transparent portion 134 of the case body 110.
[0100] (2-6) The electric vacuum cleaner 1 is equipped with a suction port body 100 relating to any of (2-1) to (2-5) described above.
[0101] By having the configuration described in (2-6) above, the electric vacuum cleaner 1 can be made to have high impact resistance and be equipped with a suction port body 100 with a light-emitting unit 200.
[0102] In addition, in the first aspect of the present invention, the suction port body 100 has a case body 110 having a curved shape portion 126 that is convex upward. However, it is also possible to configure the drive unit 170 to be located diagonally to the rear of the rotating cleaning body 160, so that the case body 110 (main case 112) has an upper surface that slopes downward from the rear to the front.
[0103] (3-1) That is, the suction port body 100 according to the third aspect of the present invention, in order to solve the same problems as the first aspect described above, comprises a case body 110 having an upper surface that slopes downward from the rear to the front and a suction port 120 on the front bottom surface, a pipe 150 connecting the suction source and the suction port 120, a light source 210 arranged to irradiate light onto the front side of the case body 110, a rotating cleaning body 160 rotatably disposed in the case body 110, a drive unit 170A that serves as a drive source for the rotating cleaning body 160, and a power transmission mechanism that transmits driving force from the drive unit 170A to the rotating cleaning body, wherein the drive unit 170A is arranged diagonally above the rear side of the rotating cleaning body 160. This allows for a shorter front-to-back length between the rotating cleaning body 160 and the drive unit 170A compared to a configuration where the drive unit 170 is located directly behind the rotating cleaning body 160. As a result, the suction port 100 can be made smaller, while also making it easier to tilt the optical axis of the light source 210 diagonally downward.
[0104] (3-2) Furthermore, in (3-1) above, at least one of (1-2) to (1-3) and (1-6) to (1-9) may be included.
[0105] ≪Variations≫ The embodiments described above are merely examples of the present invention, and without departing from the spirit of the present invention, it is possible to have configurations related to (1-1) to (1-10) and (2-1) to (2-6) described above that differ from those illustrated in the embodiments described above. Furthermore, the suction port and vacuum cleaner of the present invention may have configurations in addition to, or in place of, those included in (1-1) to (1-10) and (2-1) to (2-6) described above, or may have configurations in which some configurations are omitted. Specifically, the following modifications are possible.
[0106] In the embodiments described above, an example was shown in which the light guide portion 252 of the guide portion 250 is provided with a passage that extends linearly from one end to the other, but the present invention is not limited thereto. The guide portion 250 may also have a curved shape in which the light passage extending from one end to the other of the light guide portion 252 is bent.
[0107] In the embodiments described above, a configuration in which the cover 230 is fixed to the case body 110 was illustrated, but the present invention is not limited thereto. The guide portion 250 and the substrate 220 may also be fixed to the case body 110.
[0108] In the embodiments described above, a configuration in which the guide portion 250 and the substrate 220 are fixed together by an engagement structure was illustrated, but the present invention is not limited thereto. For example, the suction port body 100 can also be configured in which the guide portion 250 is fixed to the substrate 220 using screws, adhesive, or the like.
[0109] The present invention is not limited to the embodiments and modifications described above, and other embodiments may be possible in the spirit and teachings thereof, without departing from the scope of the claims. The components of the embodiments described above may be arbitrarily selected and combined. Furthermore, any component of the embodiments may be arbitrarily combined with any component described in the means for solving the problem, or any component that embodies any component described in the means for solving the problem. We intend to obtain rights for these as well in amendments or divisional applications of this application. [Industrial applicability]
