Description

electric vacuum cleaner

The present invention relates to an electric vacuum cleaner in which the user can arbitrarily select the rotation angle of the suction nozzle body by operating the handle body, and particularly relates to making the existence of the suction hose not obstruct or when the cleaning height is low when rotating the suction nozzle body by operating the handle body The structure around the handle body so that the suction hose does not get in the way of the occasion of the place.

In an electric vacuum cleaner, a joint device is often provided on a nozzle body connected to a handle body through a connecting pipe (extension pipe). In the existing electric vacuum cleaner, it is considered that when the connecting pipe (handle body) moves back and forth in a straight line, the suction nozzle body can be easily adapted to the horizontal and long movement form (hereinafter referred to as the first) that moves parallel to the short side direction. general cleaning (cleaning wide squares), and when the connecting pipe moves back and forth in a straight line, the longitudinal movement suitable for the nozzle body to move in parallel with its long side direction (hereinafter referred to as the second movement form) The cleaning problems such as the root of the wall are not taken into account, so there are always problems in the operability of cleaning the root of the wall.

Therefore, the applicant of the present application proposes a method of twisting the handle part of the handle body in Japanese Patent Application No. Hei 9-141374, No. The nozzle body can easily obtain the above-mentioned electric vacuum cleaner of the first moving form and the second moving form.

In each of the above-mentioned prior applications, the structure includes the first joint pipe member which is rotatably connected to the main body of the suction nozzle and can be rotated longitudinally along the vertical plane, and the first joint pipe with this first joint pipe member. The second joint pipe that is rotatably connected to the joint pipe can be rotated in the left and right direction along the plane perpendicular to the vertical plane. By twisting the handle part of the handle body, the nozzle body can be moved from the It is easy to change the posture from the first movement form to the second movement form, or from the second movement form to the first movement form.

However, in each of the above-mentioned prior applications, in the electric vacuum cleaner in which the nozzle body can obtain the above-mentioned first moving form and second moving form by twisting the handle portion of the handle body, due to the hand grip of the handle body Since the tubular part connecting the suction hose and the connecting pipe to both ends of the connecting part is integrated, if the handle part of the handle body is twisted, the suction hose connected to the tubular part will also move together with the tubular part, so sometimes The suction hose can get in the way because it is wrapped around the body. That is to say, as shown in (b) of Figure 8, when the handle portion of the handle body is rotated in the lateral direction to make the nozzle body take the second moving form, the connecting portion of the suction hose to the handle body will also Because it is placed horizontally, the suction hose may sometimes get in the way because it is wrapped around the body. Or, when the suction nozzle body adopts the first moving form to clean places such as under the bed, as shown in FIG. Due to the height, there is a problem that the connecting pipe cannot be placed in a nearly horizontal state.

Therefore, the applicant proposed in Japanese Patent Application Laid-Open No. 9-314795 that a tubular part bent into a "ヘ" shape is provided in the handle body, and the outer peripheral part of the tubular part is provided with a peripheral opening. The connection pipe joint member is rotatably attached, and the suction hose is connected to the connection pipe joint member. In the technology proposed in this Japanese Patent Application Laid-Open No. 9-314795, since the connecting pipe joint member connected to the suction hose can rotate relative to the tubular part of the handle body, even if the handle part of the handle body is turned sideways When the suction nozzle body adopts the second movement mode, since the connecting pipe joint member will rotate relatively due to the self-weight of the suction hose, the suction hose can also be kept suspended on the lower side, and the connecting pipe can be rotated by hand. The joint member can make the suction hose be in a position transverse to the handle body, and can make the connecting pipe lie in a nearly horizontal state.

However, in the technique proposed in the above-mentioned Japanese Patent Application Laid-Open No. 9-314795, the number of parts increases due to the need for a connecting pipe joint member divided into two halves, and the shape of the tubular portion of the handle body also becomes complicated. , The assembly is troublesome and the cost increases, and there is a problem that hinders the weight reduction of the handle body. In addition, there is a problem that the suction passage in the vicinity of the handle body becomes complicated, the ventilation efficiency is hindered, and noise is likely to be generated.

The present invention has been made in view of the above points, and its purpose is to realize the rotation angle of the nozzle body by operating the handle body in an electric vacuum cleaner in which the user can arbitrarily select the rotation angle of the nozzle body by operating the handle body. The existence of the suction hose does not hinder or the structure of the suction hose does not hinder when cleaning places with low heights, and the structure is simple and has good combination, and it also has excellent ventilation efficiency and noise suppression performance. .

The vacuum cleaner main body 1 is equipped with a blower fan for sucking dust into its dust collection chamber. This vacuum cleaner main body 1 is connected with one end of the suction hose 2 , and the other end of the suction hose 2 is connected with the handle body 3 . In addition, the handle body 3 is connected to one end of the connection pipe 4 , and the other end of the connection pipe 4 is connected to the nozzle body 5 . Then, the nozzle body 5 communicates with the suction passage in the cleaner main body 1 through the connection pipe 4 , the handle body 3 , and the suction hose 2 .

The vacuum cleaner main body 1 has a pair of large wheels 11 and a free wheel 12, and can be moved on the floor surface (cleaning surface) by using the handle body 3 through the suction hose 2.

The suction hose 2 has a function as a conveyance passage for conveying dust into the main body 1 of the vacuum cleaner and a function as a mechanism for pulling the main body 1 of the vacuum cleaner when it moves. hose.

The handle body 3 has the function of connecting the suction hose 2 and the connecting pipe 4, the function of moving (walking) the cleaner main body 1, the function of moving (walking) the nozzle body 5, and the function and control of the posture of the nozzle body 5 The function that the vacuum cleaner main body 1 operates. Therefore, the handle body 3 forms a dust transport passage by detachably connecting the suction hose 2 and the connection pipe 4 to communicate with the suction hose 2 and the connection pipe 4 .

In this embodiment, the structure of the handle body 3 includes a first pipe body 31 connected to the connecting pipe 4, and a second pipe body 32 connected to the suction hose 2 while being rotatably connected to the first pipe body 31. And a handle part 33 integrated with the first pipe body 31 and extending at a predetermined angle with the central axis of the first pipe body 31 .

The grip portion 33a formed at the end of the above-mentioned handle portion 33 is bent at a predetermined angle from the base portion of the handle portion 33, and the grip portion 33a of the handle portion 33 constitutes about 100° with respect to the central axis A1 of the connecting pipe 4. °～120° angle α. By forming this angle α, as shown in FIG. 2, women with average height can easily hold the grip part 33a for cleaning as shown in FIG. The rotation P1) centered on the central axis A1 of the suction nozzle body 5 can make the suction nozzle body 5 rotate relative to the connecting pipe 4 (rotation P2 in Fig. The mouth body 5 is rotated. This is because the holding portion 33a of the handle portion 33 forms an angle α with the central axis A1 of the connecting pipe 4, and by twisting the holding portion 33a, torque can be generated on the later-described joint pipe member of the suction nozzle body 5, and the joint pipe As the member, for example, the structure proposed in the aforementioned Japanese Patent Application Laid-Open No. 10-67112 can be used.

The connecting pipe 4 can communicate the movement of the handle body 3 to the nozzle body 5 while communicating with the handle body 3 and the nozzle body 5 . Since the connecting pipe 4 is composed of two pipe members in a freely expandable manner, users of this structure can adjust the length according to their preferences.

The suction nozzle body 5 has a suction nozzle body 51 with a suction nozzle for dust suction formed on its bottom surface, and when the suction nozzle body 51 is connected to the connecting pipe 4 in a relatively rotatable manner, the suction nozzle body 51 and the suction nozzle body 51 are connected to each other. The joint pipe member 52 through which the connection pipe 4 communicates. The configuration of the joint pipe member 52 includes a first joint pipe 53 whose one end side is rotatably connected to the suction nozzle main body 51 and is rotatable in the longitudinal direction in the vertical plane, and whose one end side is rotatably connected to the first joint pipe. The other end side of the pipe 53 is rotatable in the left-right direction in a plane perpendicular to the above-mentioned vertical plane, and the other end side is connected to the second joint pipe 54 of the connection pipe 4 . In addition, the details of the joint pipe member 52 will not be repeated here. As mentioned above, the structure of the joint pipe member 52 in this embodiment is the same as that described in the aforementioned Japanese Patent Application Laid-Open No. 10-67112.

Here, the suction nozzle main body 51 (the suction nozzle body 5) is in the shape of a long and thin rectangle when viewed from above. Nozzle main body 51 moves in parallel with its short side direction in a horizontally long moving form (the above-mentioned first moving form; in FIG. Arrow S1 direction moving form) and along with the connecting pipe 4 doing linear forward and backward movement, the suction nozzle main body 51 moves in parallel with its long side direction, suitable for cleaning the bottom of the wall etc. In Fig. 1 , the nozzle main body 51 moves in the direction of the arrow S2 in the state indicated by the dashed-dotted line).

The handle body 3 will be described in detail below.

FIG. 3 is a perspective view of the handle body 3 , and FIG. 4 is an exploded perspective view of the handle body 3 . FIG. 5 is a side sectional view of the handle body 3 . FIG. 6 is a side view of the handle body 3 .

In Fig. 3～Fig. 6, 31 is the first pipe body of above-mentioned handle body 3, and this first pipe body 31, as shown in Figure 5, has the central axis A2 that coincides with the above-mentioned central axis A1 of connecting pipe 4 and The ends of the connecting pipe 4 are fitted and connected.

The above-mentioned handle part 33 integrated with the first pipe body 31 forms a predetermined angle with the central axis A2 of the first pipe body 31 and extends obliquely upwards, and a curved handle is formed at the end of the handle part 33, which can be grasped by hand. The above-mentioned grip portion 33a used. In addition, as shown in FIG. 5 , a circuit board 41 for mounting control circuits, switches, light-emitting diodes, etc., and a battery 42 for powering the circuit board 41 are installed inside the handle portion 33. 33 is provided with a button 43 and a light-emitting window 44 for operating the switch. Like this, in this embodiment, through the switch operation that the button 43 of handle part 33 produces, the light signal that can be used for carrying out long-distance operation to the internal circuit of vacuum cleaner main body 1 can be sent from light-emitting diode through light-emitting window 44 and utilize ceiling reflection etc. to the light receiving unit of the main body 1 of the cleaner.

In addition, the structure of the above-mentioned second pipe body 32 rotatably connected to the first pipe body 31, as shown in FIG. 34 and the second connecting portion 35 bent downward from the first connecting portion 34 forming a predetermined angle with the central axis A3 of the first connecting portion 34 (that is, the central axis A2 of the first pipe body 31 ). In FIG. 5 , B1 is the central axis of the second connection portion 35 .

The first connecting portion 34 of the second tube body 32 is inserted into the first tube body 31 in a relatively rotatable manner, and the first connecting portion 34 of the first tube body 31 and the second tube body 32 is not connected by suitable means. Therefore, the structure of the first connecting part 34 (the second pipe body 32 ) is rotatable around the central axis A2 of the first pipe body 31 . In addition, any one of the detachment coupling means of the first connecting portion 34 of the first pipe body 31 and the second pipe body 32 can be adopted. In this embodiment, as shown in FIG. There is an annular groove 36, after the first connecting portion 34 is inserted into the first pipe body 31, a part of the anti-off sheet 38 is inserted into the annular groove 36 through the opening 37 of the first pipe body 31 to make the first The connecting part 34 and the first pipe body 31 are connected without being separated. In addition, because the installation of the anti-off piece 38 is detachable, when maintenance is required when the inside of the pipe is filled with garbage, etc., the anti-off piece 38 can be removed and the first pipe body 31 and the second pipe body 31 can be easily connected. The tube body 32 is disassembled.

In addition, as shown in FIG. 4, a connection ring 21 is connected to the end of the above-mentioned suction hose 2, and the second connection can be made by inserting the connection ring 21 into the end of the second connection part 35 of the second tube body 32. The part 35 is in contact with the suction hose 2 . In addition, 21a is the fixing part of the connecting ring 21, and 35a is the fixing part of the second connecting part 35, and the fixing part 21a and the fixing part 35a connect the second connecting part 35 and the suction hose 2 through so-called snap-in connection without disengage.

In addition, in the structure of this embodiment, the end of the suction hose 2 is rotatably held in the connecting ring 21 by suitable means, so that the second connection between the suction hose 2 and the second pipe body 32 can be achieved. The suction hose 2 is relatively rotatable with respect to the second connecting portion 35 in a state where the second connecting portion 35 is connected. Thereby, twisting of the suction hose 2 can be prevented.

As shown in Figure 6, the handle body 3 can be completed by combining the first pipe body 31 and the second pipe body 32. In the state where the suction hose 2 and the connecting pipe 4 are installed in the handle body 3, the first connecting part 34 central axis A3 (that is, the central axis A2 of the first pipe body 31 = the central axis A1 of the connecting pipe 4) and the central axis B1 of the second connecting part 35 (that is, the central axis of the end of the suction hose 2) The angle β of is set to be 90°～150°. The reason for this is that when the user stands and holds the grip part 33a of the handle part 33 of the handle body 3 during cleaning, the suction hose 2 must become a shape that hangs obliquely downward, and it is easy to pull the vacuum cleaner. The main body 1 moves without obstructing the hand holding the grip portion 33 a of the handle portion 33 .

In addition, FIG. 7 shows a cross-sectional view of the grip portion 33a of the handle portion 33 of the handle body 3. As shown in the figure, the cross-section of the grip portion 33a forms an approximately inverted triangle with rounded corners. The reason for this is that when the user holds the grip part 33a, it is easy to hold and can always sense the top of the bottom surface of the grip part 33a through the sense of touch, and can easily recognize the handle part 33 (grip part 33a) by the sense of touch. The torsion state and the neutral state of the reason.

Next, the operation of this embodiment will be described.

Assume that when the nozzle body 5 takes the above-mentioned first moving form, the handle portion 33 (grip portion 33a) of the handle body 3 is twisted about 90°, so that the nozzle body 5 takes the above-mentioned second moving form. That is, as shown in FIG. 3, the handle portion 33 is twisted (rotated) about 90° in the direction of the arrow R1, so that the posture of the nozzle body 5 is transferred from the first moving form to the second moving form. At this time, the first pipe body 31 and the second pipe body 32 integrated with the handle part 33 are connected in a form that can rotate relative to each other, and since the self-weight of the suction hose 2 connected to the second pipe body 32 is always working, Even if the handle portion 33 rotates in the direction of the arrow R1, the torque in the direction of the arrow M1 produced by the suction hose 2 acts on the second pipe body 32, and as a result the second pipe body 32 maintains its original rotation. position, the suction hose 2 will not be lifted and maintain its original state.

However, as shown in Figure 8(a), even if the handle portion 33 of the handle body 3 is turned sideways to make the nozzle body 5 take the second moving form, the connecting portion of the suction hose 2 and the handle body 3 will not It will be lifted, and the suction hose 2 will remain suspended on the lower side of the handle body 3, so the suction hose 2 will not wrap around the user's body, which is easy to use.

In addition, in this embodiment, when the suction nozzle body adopts the first moving form to clean places with low heights such as under the bed, as shown in FIG. The body 31 can be rotated about 90° so that the suction hose 2 connected to the handle body 3 is in a nearly horizontal state at approximately the same height as the first pipe body 31, and the connecting pipe 4 can be in a nearly horizontal state, which can be easily cleaned. It is also convenient to use in the innermost place of a place with a low height.

In addition, in this embodiment, since the suction hose 2 can rotate relative to the second tube body 32, even if the suction hose 2 is twisted during storage, or the suction hose 2 is twisted due to an intentional wrong operation Occasionally, since the rotation of the second pipe body 32 and the rotation of the suction hose 2 are easy to return the suction hose 2 to the untwisted state as shown in FIG. 2, it is also very convenient to use at this point.

In addition, in the structure of this embodiment, the approximate center of the gripping portion 33a of the handle portion 33 is located on the extension line of the central axis A1 of the connecting pipe 4, so that the grip of the handle portion 33 Between the part 33a and the connecting pipe 4, the second pipe body 32 (suction hose 2) can be rotated relative to the above-mentioned central axis A1, so there is no burden on the wrist, and the operability of the twisting operation of the handle body 3 is good. And, as the means of realizing this kind of structure, what adopt is to be positioned at the middle of the holding portion 33a and the first pipe body 31 on the extension line of the central axis of the connecting pipe 4 (the first pipe body 31), with respect to the above-mentioned central axis. A1 is a structure that is simple, has a small number of parts, and is easy to assemble by rotatably assembling the second pipe body 32 that holds the end of the suction hose 2 . In addition, in addition to the simple structure of the handle body 3, since the curved portion of the suction passage in the handle body 3 as a whole has only one gently curved portion, resistance to ventilation and air leakage can be reduced.

In addition, since the rotation axis of the first connecting portion 34 of the second pipe body 32 relative to the central axis A1 coincides with the above-mentioned central axis A1, the relative rotation of the second pipe body 32 relative to the twisting motion of the handle body 3 can be improved. sex. That is to say, because in the present embodiment described above, the central axis of the first pipe body 31 coincides with the central axis of the first connecting portion 34 of the second pipe body 32, the twisted first pipe body along with the handle portion 33 31 torque, except for the frictional resistance between the cylindrical surfaces, will not act on the first connecting part 34 (the second pipe body 32) at all, so for the twisting action of the handle body 3, the relative movement of the second pipe body 32 Excellent follow-up of rotation.

Here, the rotation axis of the first connecting portion 34 of the second pipe body 32 is preferably coincident with the above-mentioned central axis A1, and the tolerable inclination range is within 0° to 30° of the coincidence. That is, depending on the situation, even if the torque of the first pipe body 31 acts to some extent on the first connecting portion 34 (second pipe body 32 ), it does not matter practically. That is to say, even if the central axis of the first pipe body 31 is bent so that the central axis of the connecting portion with the first connecting portion 34 of the first pipe body 31 is inclined within 30° relative to the central axis A1 of the connecting pipe 4, it does not matter .

In addition, in this embodiment, since there are two rotating parts corresponding to the twisting motion of the handle body 3 and a rotating part for preventing the suction hose 2 from being twisted, the twisting of the suction hose 2 can be reduced. The bad influence of the vacuum cleaner main body 1 can be excellent in pulling mobility and attractiveness.

In addition, since each part of the handle body 3 can be easily attached and detached, assemblability and maintainability can be improved. In addition, the above has not yet been involved, the first tube body 31 and the handle part 33 of the handle body 3 are composed of a lower shell that includes a part of the first tube body 31 and the handle part 33 and an upper shell that includes the rest of the handle part 33. The case structure, the circuit board etc. are arranged between the lower case and the upper case, can further improve the assembly property.

As mentioned above, in this embodiment, since the handle body 3 is constituted such that the first pipe body 31 and the second pipe body 32 of the handle body 3 can be connected in a rotatable manner, it is simple, the number of parts is small, and Assemblability is good, and the light weight structure can be realized. When the suction nozzle body is rotated by operating the handle body 3, the existence of the suction hose 2 will not cause hindrance, or when cleaning a place with a low height, the suction soft The presence of tube 2 doesn't get in the way. In addition, since there is only one bend in the suction path of the handle body 3, ventilation efficiency and noise suppression performance are excellent.

Next, a second embodiment of the present invention will be described using FIG. 10 . 10 is an exploded perspective view showing a second pipe body of a handle body and an end portion of a suction hose of an electric vacuum cleaner according to a second embodiment of the present invention. In addition, in FIG. 10, the same reference numerals are given to the components of the above-mentioned embodiment, and the description thereof will not be repeated in order to avoid duplication (the same applies to the third embodiment below).

In the first embodiment shown in FIGS. 1 to 9 , an electric vacuum cleaner in which the vacuum cleaner main body 1 is operated by wireless remote control of optical signal transmission is described, but the present invention is not limited thereto. For example, the present invention is also applicable to mechanically and electrically connecting the suction hose 2 with wiring between the handle body 3 and the vacuum cleaner main body 1, and operating the vacuum cleaner main body 1 by means of the switch of the handle body 3, or from the handle body 3. An electric vacuum cleaner in which the wiring is extended to the motor for driving the rotating brush provided in the nozzle body 5 through the connecting pipe 4 with wiring, and the driving motor is operated by the operation switch of the handle body 3 .

This is illustrated in Figure 10 in detail. In this embodiment, a wiring ring 101 is provided on the inner peripheral surface of the above-mentioned connection ring 21, and a part of its outer circumference is freely rotatable. The conductive endless belt 102 is connected and fixed to the lower side of the conductive endless belt 102 with the connection portion 103a of the first connecting wire 103 arranged on the suction hose 2 . In this way, the wiring ring 101 and the end of the suction hose 2 are integrated, and the suction hose 2 can rotate 360° relative to the connecting ring 21 .

In addition, the connection of the connection ring 21 is freely attachable and detachable. Therefore, on the above-mentioned second connection part 35 of the second pipe body 32 that rotatably holds the suction hose 2 (wiring ring 101), a connection to the hand is arranged. The contact 104a provided on the end of the second connection line 104 of the circuit board in the part 33, the contact 104a is always in elastic contact with the conductive ring 102 on the wiring ring 101. That is to say, the contact 104 a is pressed onto the conductive ring 102 through the protruding portion 105 a of the detachable pressing piece 105 provided as a part of the second connecting portion 35 .

Therefore, for the second connection portion 35 of the second pipe body 32, no matter which rotation position the suction hose 2 (wiring ring 101) takes, the first connection line 103 issued from the suction hose 2 and the inside of the second pipe body 32 The second connecting wire 104 can always maintain a stable electrical connection. In addition, according to this connection structure, after the connection ring 21 is inserted into the second connection portion 35 of the second pipe body 32, the contact between the conductive ring 102 of the wiring ring 101 and the contact 104a can be obtained, and the workability can be realized. Good and secure wiring.

In addition, in this embodiment (and the aforementioned first embodiment), the suction hose 2 is installed so that it can rotate relative to the connecting ring 21, but it is also possible to fix the suction hose 2 on the connecting ring 21 so that the connecting ring 21 is opposite to each other. The second connecting portion 35 of the second pipe body 32 rotates. In this case, the above-mentioned drop-off preventing piece 38 can be used.

On the other hand, at the end of the first connecting portion 34 of the second pipe body 32, a recessed and annular wiring accommodating portion 106 is formed, and a part of the second connecting wire 104 is accommodated in this wiring accommodating portion 106. , and the end of the second connecting wire 104 has been connected to the circuit substrate in the handle portion 33 and the circuit substrate. In the present embodiment, since the second connecting wire 104 is accommodated in the wiring accommodating portion 106, the second connecting wire 104 has a sufficient margin for rotation, and the second pipe body 32 is opposite to the above-mentioned first pipe body 31. Even if the rotation reaches the degree of 90° left and right, the second connecting wire 104 will not be tightened and broken, that is to say, even if the second pipe body 32 and the first pipe body 31 are relatively rotated, the electrical connection generated by the second connecting wire 104 The state will also remain stable. This is because the handle body 3 is configured such that it can turn left and right by approximately 90° in the present embodiment.

Due to this structure, the electrical connection can be ensured when the handle body 3 is twisted without using the wiring ring 101 . In other words, since the connection wire has a margin corresponding to the length of the rotational movement range caused by the twisting of the handle body 3, the electrical connection can be ensured with a simple structure. In addition, it does not matter even if the connection structure using the above-mentioned wiring ring 101 etc. is used for the 2nd pipe body 32 and the 1st pipe body 31.

In addition, in the case where the electrical connection reaches the nozzle body 5, a known connecting pipe for connecting the circuit board in the handle portion 33 and the nozzle body 5 can be used.

Fig. 11 is a diagram of a third embodiment of the present invention. In this embodiment, an auxiliary piece 111 is installed on the connecting pipe 4, so that the posture of the electric vacuum cleaner can be compact and stable when stored.
