  In the conventional suction port body, for example, four wheels are arranged at the front, rear, left and right corners of the bottom surface while avoiding the suction port, and consideration is given to the stability of straightness and turning performance. In addition, even if it is difficult to arrange the four wheels at the front, back, left, and right corners of the bottom surface of the conventional suction port body, the distance between the wheels is separated as much as possible, especially the distance between the wheel pairs aligned in the left-right direction of the suction port body ( The so-called tread is separated, and consideration is given to the stability of straightness and turning performance.

  By the way, a vacuum cleaner is provided with the extension pipe | tube and hand operation pipe | tube which are a part of flow path which connects an electric blower and a suction inlet body. The extension pipe is a straight pipe, and one end is connected to the suction port body and the other end is connected to the local operation pipe. The hand control tube includes a grip portion that allows a user of the vacuum cleaner to perform a grip operation of the suction port body. The user of the electric vacuum cleaner holds the grip portion, repeats bending and stretching of the elbow, and reciprocates the suction port body in the front-rear direction to clean the surface to be cleaned.

  On the other hand, the suction port body includes a universal joint that mechanically and fluidly connects the suction port and the extension pipe. This universal joint is a part of the flow path, and mechanically adjusts the relative angular change between the extension pipe and the suction port that changes every time the suction port moves. Generally, a universal joint is located in the center of the rear part of a suction inlet.

  The suction port body travels using the user's operation force transmitted by the extension pipe as a driving force. This propulsive force acts particularly in the direction of pressing the suction port against the surface to be cleaned when moving forward. That is, the operating force at the time of forward movement acts in a direction in which the rear center portion of the suction port body is pressed against the surface to be cleaned.

  Here, attention is paid to the support condition and load condition of the suction port on the surface to be cleaned. First, the suction port body is supported on the surface to be cleaned with a wheel located far away in the left-right direction as a support point. On the other hand, the suction port body receives an operating force from a universal joint at a substantially central position of a pair of left and right wheels that are support points. From the support condition and the load condition, the suction port body that is moving forward is deformed into a bow shape that brings the central portion in the width direction closer to the surface to be cleaned. This deformation causes the axles of the left and right wheel pairs aligned on a substantially straight line or the axles of the front and rear wheel pairs aligned substantially parallel to each other. The inclination of the axle between the left and right wheels may increase running resistance and may impair the straightness and turning performance of the suction port body.

  Therefore, the present invention proposes a suction port body and a vacuum cleaner that can suppress the inclination of the axle between a plurality of wheels that support the suction port body so as to be able to travel and can stabilize the traveling performance and the turning performance.

  In order to solve the above-mentioned problem, a suction port body according to an embodiment of the present invention includes a suction port body having a suction port that opens on a bottom surface and enclosing a flow path connected to the suction port, and a rear center of the suction port body And a plurality of wheels that are positioned on the bottom surface and that sandwich the region from the left and right and are arranged in front and back in proximity to the front projection region of the connection tube and the connection tube in plan view.

  The main body case 5 has a main body connection port 12 as a joint to which the pipe portion 3 can be attached and detached. The main body connection port 12 is a fluid inlet of the vacuum cleaner main body 2 and fluidly connects the pipe portion 3 and the dust separation and dust collection portion 7.

  The dust separating and collecting part 7 is from air containing dust (hereinafter referred to as “dust-containing air”) that flows from the surface to be cleaned through the tube part 3 and the main body connection port 12 by the negative pressure generated by the electric blower 8. Dust is separated, collected, accumulated, and air is sent to the electric blower 8.

  The electric blower 8 sucks air passing through the dust separation and collection unit 7 and generates negative pressure.

  The main body control unit 9 includes a microprocessor (not shown) and a storage device (not shown) that stores various calculation programs and parameters executed by the microprocessor. The main body control unit 9 stores a plurality of preset operation modes in the storage device. The plurality of operation modes set in advance correspond to operation signals received from the pipe section 3 and have different input values (input values of the electric blower 8) as differences between the operation modes. When receiving the operation signal from the pipe unit 3, the main body control unit 9 selectively selects an arbitrary operation mode corresponding to the operation signal from a plurality of preset operation modes and reads it from the storage unit. The operation control of the electric blower 8 is performed according to the above.

  The power cord 11 includes a power plug 14 at the free end.

  The pipe part 3 sucks dust-containing air from the surface to be cleaned and guides it to the cleaner body 2 by the negative pressure acting from the cleaner body 2 as the electric blower 8 is operated. The pipe portion 3 includes a connection pipe 19 as a joint that is detachably connected to the cleaner body 2, a dust collection hose 21 that is fluidly connected to the connection pipe 19, and a manual operation that is fluidly connected to the dust collection hose 21.

  The connection pipe 19 is a joint that can be attached to and detached from the main body connection port 12, and is fluidly connected to the dust separating and collecting part 7 through the main body connection port 12.

  The dust collection hose 21 is a long and flexible substantially cylindrical hose. One end of the dust collection hose 21 (here, the rear end) is connected to the connecting pipe 19. The dust collecting hose 21 is fluidly connected to the dust separating and collecting part 7 through the connecting pipe 19.

  The hand operation tube 22 is interposed between the dust collection hose 21 and the extension tube 25. One end portion (here, the rear end portion) of the hand operation tube 22 is connected to the other end portion (here, the front end portion) of the dust collecting hose 21. The hand operating tube 22 is fluidly connected to the dust separating and collecting unit 7 through the dust collecting hose 21 and the connecting tube 19.

  The grip portion 23 is a portion that the user grips with his / her hand to operate the vacuum cleaner 1. The grip portion 23 has an appropriate shape that can be easily gripped by a user with a hand and protrudes from the hand operation tube 22.

  The operation unit 24 includes a switch corresponding to each operation mode. Specifically, the operation unit 24 includes a stop switch 24 a corresponding to the operation stop operation of the electric blower 8 and an activation switch 24 b corresponding to the operation start operation of the electric blower 8. The stop switch 24 a and the start switch 24 b are electrically connected to the main body control unit 9. The user of the vacuum cleaner 1 can alternatively select the operation mode of the electric blower 8 by operating the operation unit 24. After the electric blower 8 starts operation, the start switch 24b also functions as an operation mode selection switch. In this case, every time the operation signal is received from the start switch 24b, the main body control unit 9 switches the operation mode as strong → medium → weak → strong →. The operation unit 24 may separately include a weak operation switch (not shown), a medium operation switch (not shown), and a strong operation switch (not shown) instead of the start switch 24b.

  The extension tube 25 is an elongated substantially cylindrical tube that can be expanded and contracted. The extension tube 25 has a telescopic structure in which a plurality of cylindrical bodies are overlapped. One end portion (here, the rear end portion) of the extension tube 25 is detachably connected to the other end portion (here, the front end portion) of the hand operation tube 22. The extension pipe 25 is fluidly connected to the dust separating and collecting part 7 via the hand operation pipe 22, the dust collecting hose 21 and the connecting pipe 19.

  The suction port body 26 is detachably connected to the other end portion (here, the front end portion) of the extension pipe 25. The suction port body 26 has a structure capable of running or sliding on a surface to be cleaned such as a wooden floor or a carpet, and has a suction port 28 on the bottom surface facing the surface to be cleaned in the running state or the sliding state. Further, the suction port body 26 includes a rotary cleaning body 29 that is located at the suction port 28 and is rotatable, and an electric motor 31 that can rotationally drive the rotary cleaning body 29. The suction port body 26 is fluidly connected to the dust separating and collecting part 7 through the extension pipe 25, the hand operating pipe 22, the dust collecting hose 21 and the connecting pipe 19.

  When the vacuum cleaner 1 receives the operation of the start switch 24b, the electric vacuum blower 8 starts to operate and generates a negative pressure (suction negative pressure) inside the cleaner body 2. For example, when the electric blower 8 is operated with the start switch 24b in a state where the electric blower 8 is stopped, the electric blower 8 is first operated in the strong operation mode, and then when the operation of the start switch 24b is received, the electric blower 8 is turned on. When the operation is performed in the operation mode and the operation of the start switch 24b is further received, the electric blower 8 is operated in the weak operation mode, and the following is repeated. The strong operation mode, the intermediate operation mode, and the weak operation mode are a plurality of operation modes that are set in advance, and the input values are smaller in the order of the strong operation mode, the intermediate operation mode, and the weak operation mode.

  The negative pressure generated inside the vacuum cleaner main body 2 is sucked into the suction port body 26 through the dust separating and collecting part 7, the main body connection port 12, the connection tube 19, the dust collection hose 21, the hand operation tube 22 and the extension tube 25. Acts on the mouth 28. Due to the negative pressure acting on the suction port 28, the vacuum cleaner 1 sucks dust collected on the surface to be cleaned together with air from the suction port 28 to clean the surface to be cleaned. The dust separating and collecting unit 7 separates, collects, and accumulates dust from the dust-containing air sucked by the suction port 28. The air that has been separated and cleaned from the dust-containing air passes through the dust separation and collection unit 7 and the electric blower 8 and is exhausted outside the cleaner body 2.

  The suction port body 26 will be further described in detail.

  FIG. 2 is a perspective view of the top surface side showing the suction port body according to the embodiment of the present invention.

  FIG. 3 is a bottom perspective view showing the suction port body according to the embodiment of the present invention.

  As shown in FIGS. 2 and 3, the suction port body 26 according to the present embodiment has a flat, substantially rectangular parallelepiped box-like suction port body 32 that is short in the front-rear direction, which is the advancing direction, and a suction port body.

  Further, the lower case 37 includes a plurality of, for example, four wheels 41 on the bottom surface 35. When the suction port body 26 is placed on the surface to be cleaned with the bottom surface 35 facing the surface to be cleaned, the wheel 41 has a space between the bottom surface 35 and the surface to be cleaned and a suction port body 26 or a suction port body 32. It supports to the state that can run. The four wheels 41 are divided into two sets of a pair of left and right wheels 42 in the vicinity of the opening edge of the suction port 28 and a pair of left and right wheels 43 in the rear bulging portion 39 of the lower case 37. The distance between the 41 pairs (so-called wheel base) is increased.

  The wheel 41 includes axles that are parallel to each other in the left-right direction (width direction) of the suction port body 26 in order to make the suction port body 26 move forward and backward smoothly. Further, the wheel widths of the wheels 41 arranged in the front-rear direction overlap with each other when viewed in the front-rear direction.

  Moreover, the suction inlet 26 is provided with the raising cloth 46 which has the raising 45 which is located between the wheels 41 located in a line at the front and back, and which can be grounded to the surface to be cleaned together with the wheels 41. The raised cloth 46 extends substantially in parallel with the axle of the wheel 41. The raised cloth 46 follows the trajectory of the wheel 41 as the suction port body 26 advances and retreats. The running trace of the wheel pair 43 on the side is polished to reduce the running trace remaining on the surface to be cleaned.

  The connection pipe part 33 is a universal joint that mechanically and fluidly connects the suction port body 26 to the extension pipe 25, and includes a rotary connection pipe part 48 and a swinging connection pipe part 49.

  The rotary connection pipe portion 48 is connected to the suction port body 32 and is rotatable about an axis (an axis that coincides with the X axis or an axis parallel to the X axis) along the front-rear direction of the suction port body 26.

  The swing connection pipe portion 49 can swing around an axis orthogonal to the rotation axis of the rotary connection pipe portion 48. The free end of the swing connection pipe portion 49 is a joint that can be attached to and detached from the extension pipe 25.

  The rotary cleaning body 29 is an axial cleaning body that extends in the left-right direction of the suction port body 32, and includes a plurality of bristle brushes 51 that extend in the radial direction in a spiral shape and in multiple lines. In addition to the bristle brush 51, the rotary cleaning body 29 may include a blade made of flexible silicone rubber or the like that extends in the radial direction in a spiral and multi-row manner.

  FIG. 4 is a longitudinal sectional view showing a suction port body according to the embodiment of the present invention.

  As shown in FIG. 4, the suction port body 26 according to the present embodiment supports the cleaning body chamber 53 that houses the rotary cleaning body 29, the connection pipe portion 33, and the fluid between the cleaning body chamber 53 and the connection pipe portion 33. And a relay pipe 55 to be connected to each other.

  The cleaning body chamber 53 is a part of a flow path having the suction port 28 as an inlet. The cleaning body chamber 53 holds the rotary cleaning body 29 in a rotatable state. A part of the rotary cleaning body 29, specifically, the tip of the bristle brush 51 protrudes downward from the suction port 28, and comes into contact with the surface to be cleaned when the suction port body 26 is placed on the surface to be cleaned.

  The relay pipe 55 is in the suction inlet body 32 and extends in the front-rear direction. The relay pipe 55 rotatably supports the connection pipe part 33 and fluidly connects the cleaning body chamber 53 and the connection pipe part 33. Specifically, the front end of the relay pipe 55 is fluidly connected to the cleaning body chamber 53, and the rear end of the relay pipe 55 is fluidly connected to the connection pipe portion 33 and supports the connection pipe portion 33 rotatably. . The relay pipe 55 includes a flange 56 that rotatably supports the connection pipe portion 33, particularly the rotary connection pipe portion 48. The flange 56 extends from the opening end of the relay pipe 55 in a radially outward direction. The rotary connecting pipe portion 48 covers the flange 56 and slides or slides in the circumferential direction and is integrated with the relay pipe 55.

  Further, the relay pipe 55 is sandwiched between the lower case 37 and the upper case 38 and is firmly fixed to integrate the suction port main body 32 and the connection pipe portion 33, so that the operation force applied to the extension pipe 25 is applied to the suction port main body 32. Tell.

  FIG. 5 is a plan view showing the upper case removed from the suction port body according to the embodiment of the present invention.

  As shown in FIG. 5, the suction port 28 of the suction port body 26 according to the present embodiment opens greatly in the width direction of the front half of the lower case 37. The opening edge of the suction port 28 is connected to a partition wall 58 extending in the height direction of the lower case 37. The partition wall 58 partitions the cleaning body chamber 53. The rotary cleaning body 29 is housed in the cleaning body chamber 53.

  The ceiling of the cleaning body chamber 53 is an upper case 38. That is, the lower case 37 and the upper case 38 cooperate to partition the cleaning body chamber 53.

  The relay pipe 55 is located at the center of the rear half of the lower case 37. The relay pipe 55 is a pipe having a maximum diameter substantially the same as that of the connection pipe portion 33, particularly the rotary connection pipe portion 48, and substantially fits in the front projection area S (between the two-dot chain lines in FIG. 5). .

  The electric motor 31 is located on the left side of the relay pipe 55 and is housed in the lower case 37. The electric motor 31 rotationally drives the rotary cleaning body 29 via an endless belt 59 extending forward and backward through the left end portion of the lower case 37.

  The wheel pair 42 in the vicinity of the opening edge of the suction port 28 is close to the relay pipe 55 in a plan view and sandwiches it from the left and right. The distance between the wheel pairs 42 (so-called tread) is positioned so as to be close to the relay pipe 55 while slightly exceeding the width dimension of the relay pipe 55 in the left-right direction.

  On the other hand, the wheel pair 43 located at the rear bulging portion 39 of the lower case 37 is close to the connecting pipe portion 33, more specifically, the rotating connecting pipe portion 48 in plan view, and sandwiches it from the left and right. The distance between the wheel pair 43 is positioned so as to be close to the rotary connecting pipe 48 while slightly exceeding the diameter of the rotary connecting pipe 48.

  Accordingly, the four wheels 41 are adjacent to the connecting pipe portion 33 and the relay pipe 55 (that is, the front projection area of the connecting pipe portion 33) for each of the wheel pairs 42 and 43 in plan view, and sandwich this region from the left and right sides and back and forth. Lined up. The four wheels 41 surround the rotary connecting pipe portion 48 and the relay pipe 55 that are a connecting portion between the connecting pipe portion 33 and the suction port body 32 in plan view. In particular, the relay pipe 55 is located inside a quadrangle having four wheels 41 as apexes. In other words, the four wheels 41 surround the relay pipe 55 from four directions in plan view.

  The suction port body 26 according to the present embodiment travels by operating force applied to the suction port body 26 from the extension pipe 25 (that is, the propulsive force of the suction port body 26). The operating force applied to the suction port body 26 acts on the suction port body 32 from the extension pipe 25 through the connection pipe portion 33 and the relay pipe 55. The operating force applied to the suction port body 26 acts in the direction of pressing the suction port body 26 against the surface to be cleaned, particularly when the suction port body 26 moves forward.

  At this time, paying attention to the width direction of the suction port body 26, the suction port body 26 behaves like a beam with the wheel 41 as a support point and causes bending deformation.

  Here, focusing on the width direction of the suction port body, the deformation state of the conventional suction port body will be described. The suction port behaves like a beam with left and right wheels as support points, and causes bending deformation. The operating force that acts on the suction port body from the extension pipe through the connecting pipe portion is an external force that promotes this bending deformation. In the case of the conventional suction port body, since the distance between the pair of left and right wheels (so-called tread) is wide in the width direction of the suction port body, the amount of bending deformation of the suction port body due to the operating force applied to the suction port body increases. . This bending deformation of the suction port body tilts the axles of the left and right wheels that were in a substantially straight line or parallel positional relationship before the deformation. The inclination of the axle between the left and right wheels may increase running resistance and may impair the straightness and turning performance of the suction port body.

  On the other hand, since the suction port body 26 according to the present embodiment has the wheels 41 disposed in the vicinity of the connecting pipe portion 33 and the relay pipe 55 (that is, the front projection region of the connecting pipe portion 33), the operation force is reduced. The wheel 41 is close to the receiving portion, and the distance between the wheel pair 42 and 43 is remarkably narrow compared to the conventional one. In particular, in the suction port body 26 according to the present embodiment, the wheel pairs 42 and 43 are arranged in the vicinity of the connection pipe portion 33 and the relay pipe 55 that transmit the operation force. That is, the suction port body 26 according to the present embodiment has a short distance between the support points that support the suction port body 32 and is less likely to be bent by an operating force applied to the suction port body 32 than the conventional suction port body. Since the suction inlet body 32 is not easily bent, the inclination generated between the axles is small. Therefore, the suction port body 26 according to the present embodiment has a small axle inclination between the wheels 41, suppresses running resistance, and has high straightness and turning performance.

  Therefore, according to the vacuum cleaner 1 and the suction port body 26 according to the present embodiment, the traveling performance and the turning performance can be stabilized by suppressing the inclination of the axle between the plurality of wheels 41 that support the suction port body 26 so as to travel.

  The vacuum cleaner 1 according to the present invention is not limited to the canister type vacuum cleaner 1, and may be an upright type, a stick type, a handy type, or an autonomous type vacuum cleaner 1.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
