Description

  Embodiments according to the present invention relate to a vacuum cleaner hose and a vacuum cleaner.

  2. Description of the Related Art A hose for a vacuum cleaner that includes a joint pipe that is detachably connected to a vacuum cleaner body is known. The hose for an electric vacuum cleaner includes a flexible hose and a connecting pipe that can rotate around their center lines so as not to impair the swirlability of the vacuum cleaner body. Specifically, a fixed pipe is provided at the end of the flexible hose, and a support structure is provided that is fitted into the joint pipe to prevent the pipe from rotating.

  By the way, some flexible hoses include a conducting wire that energizes from an end on the cleaner body side to an end on the opposite side.

  Therefore, a conventional vacuum cleaner hose has a plurality of pins that are electrically connected to the vacuum cleaner main body in the vicinity of the clamp that fixes the joint pipe to the vacuum cleaner main body and on the opposite side of the joint pipe as viewed from the clamp. The external connection terminal is provided.

JP-A-10-85160

  Generally, only one clamp for fixing the vacuum cleaner hose to the vacuum cleaner body is provided. Further, the fitting between the joint pipe of the vacuum cleaner hose and the vacuum cleaner body has a clearance fit.

  For this reason, in order to ensure the energization of the external connection terminal that electrically connects the vacuum cleaner hose and the vacuum cleaner main body, the external connection terminal is arranged as close as possible to the clamp, It is preferable to avoid the influence of the gap. That is, it is desirable to avoid disposing the external connection terminal on the opposite side of the clamp even if it is a part of the external connection terminal as in a conventional vacuum cleaner hose.

  On the other hand, when the external connection terminals are intensively arranged in the vicinity of the clamp, it becomes difficult to secure a space for electrical connection between the lead wire laid on the hose and the external connection terminals. For example, it is conceivable that the electrical connection portion between the conducting wire laid on the hose and the external connection terminal, that is, the internal connection terminal is displaced in the longitudinal direction of the joint pipe while avoiding the vicinity of the clamp. However, in such a structural mode, the joint structure of the hose end is extended in the longitudinal direction. When the joint structure is extended in the longitudinal direction, the length of the joint pipe projecting from the cleaner body becomes longer, and the turning radius of the cleaner body including the connecting pipe is enlarged, which is inconvenient from the viewpoint of small turning.

  Therefore, the present invention concentrates the external connection terminals that are responsible for electrical connection with the cleaner body in the vicinity of the clamp that fixes the joint structure to the cleaner body without enlarging or extending the longitudinal dimension of the joint structure. It aims at proposing the hose for vacuum cleaners and a vacuum cleaner which can be arrange | positioned.

In order to solve the above problems, a vacuum cleaner hose according to an embodiment of the present invention includes a flexible hose, a rotary tube fixed to an end of the hose, and a plurality of annular tubes provided on the rotary tube.

  The cleaner body 2 drives the electric blower 8 with the electric power supplied through the power cord 11, and causes the negative pressure generated by the drive of the electric blower 8 to act on the pipe part 3. The vacuum cleaner 1 sucks air containing dust (hereinafter referred to as “dust-containing air”) from the surface to be cleaned through the pipe portion 3, separates the dust from the dust-containing air, and collects the separated dust. Then, clean air from which dust has accumulated and exhausted is exhausted.

Specifically, the operation unit 24 includes a stop switch 24 a associated with an operation stop operation of the electric blower 8 and an activation switch 24 b associated with an 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. The start switch 24 b also functions as an operation mode selection switch during operation of the electric blower 8. In this case, every time the operation signal is received from the start switch 24b, the main body controller 9 switches the operation mode in the order of strong → medium → weak → strong →. Note that the operation unit 24 may individually 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.

That is, the suction port body 26, the extension tube 25, the hand operation tube 22, the dust collection hose 21, the connection tube 19, and the dust separation device 7 are suction air passages that lead from the electric blower 8 to the suction port 28.

  The electric vacuum cleaner 1 starts the electric blower 8 when accepting a user operation on the start switch 24b. For example, when the start switch 24b is operated in a state where the electric blower 8 is stopped, the electric vacuum cleaner 1 first operates the electric blower 8 in the strong operation mode, and when the start switch 24b is operated again, the electric blower. 8 is operated in the medium operation mode, and when the start switch 24b is operated three times, the electric blower 8 is operated in the weak operation mode, and the same is repeated thereafter. The strong operation mode, the medium operation mode, and the weak operation mode are a plurality of operation modes set in advance, and the input value to the electric blower 8 is small in the order of the strong operation mode, the medium operation mode, and the weak operation mode. The started electric blower 8 exhausts air from the dust separation device 7 to make the inside thereof a negative pressure (suction negative pressure).

  The negative pressure of the dust separator 7 acts on the suction port 28 through the main body connection port 12, the connection tube 19, the dust collection hose 21, the hand operation tube 22, the extension tube 25, and the suction port body 26 in order. The vacuum cleaner 1 cleans the surface to be cleaned by sucking dust on the surface to be cleaned together with air by the negative pressure applied to the suction port 28. The dust separating device 7 separates and accumulates dust from the dust-containing air sucked into the electric vacuum cleaner 1, and sends clean air after separating the dust to the electric blower 8. The electric blower 8 exhausts the air sucked from the dust separator 7 to the outside of the cleaner body 2.
