The distance between the hose rollers 116 is formed larger than the diameter of the hose 105, and the brush 118 fixed to the hose roller 116 has a size that can be inserted into the corrugations 117 formed in the hose 105. It would be desirable to have.

Fixing the brush 118 to the hose roller 116 to accommodate and withdraw the hose 105 allows the user to artificially transmit the driving force required for the storage and withdrawal to the hose 105. This is to allow the hose 105 to be easily pulled out from the brush 118, regardless of the driving force of the hose roller 116, even if the hose 105 is pulled out strongly.

At one side of the lower and upper rollers 114 and 115 constituting the hose roller 116, the lower and upper gears 119 and 120 are fixed to engage each other, and the lower gear 119 is located on the lower side of the device body 113. It engages with the prime mover 123 fixed to the output shaft 122 of the mounted drive motor 121 to rotate the hose roller 116 forward and backward.

In front and rear of the hose roller 116, a funnel-shaped front guide 125 and a rear guide 126 having large inlet and outlet diameters so as to stably guide the hose 105 to be stored and drawn out are further provided. Equipped.

The front and rear guides 125 and 126 are provided with a front sensor 127 and a rear sensor 128 for detecting the suction nozzle 104 at the front end of the hose 105 and the rear end of the hose 105 to stop receiving and withdrawing operations. Then, it is applied to the controller to stop the operation of the driving motor 121.

The suction nozzle 104 and the rear end of the hose 105 can be sensed by attaching a metal ring to the rear end of the suction nozzle 104 and the hose 105, or a known sensor body capable of communicating with each other is built-in. It will be possible to perform variously, such as configuring.

In addition to allowing the speed of the drive motor 121 to be controlled through the controller, it will be natural to enable control such as the length of the hose 105 to be drawn out, the stop during the withdrawal, and the stop during the receiving process. Since the technical content is well known in the related industry, a detailed description will be omitted.

The hose control device 110 may be made of a non-ferrous metal such as aluminum so as to minimize the load applied to the boom stand 103 through weight reduction in consideration of the fact that it is mounted on the boom stand 103, but the price or ease of manufacture, etc. Considering this, it would be desirable to construct a lightweight plastic material.

In the middle of the boom stand 103, a hose storage means 130 may be further provided to prevent entanglement by neatly aligning the hoses 105 received after use.

The hose storage means 130, a stopper 131 that performs a function of pulling the hose 105 at the beginning of storage and stops further withdrawal, and a hose that prevents the hose 105 from being entangled. It consists of a storage unit 132.

The stopper 131 is equipped with a stopper body 134 having a take-up reel 133 that always imparts rotational force in the winding direction by having a built-in spring on the boom stand 103, and the wire wound on the take-up reel 133 (135) is connected to the tail of the hose (105) when withdrawn, when the wire 135 is completely released from the winding reel 133, further withdrawal is stopped, and at the time of storage, the hose control device 110 is connected to the hose 105 When pulling ), the tail of the hose 105 is pulled to the hose storage port 132 by the force of the spring mounted on the winding reel 133.

The hose storage unit 132 is configured by forming an accommodation space 136 of a tube body, a mesh body, or a wire so that the hose 105 accommodated from the stopper 131 to the lower position of the boom unit 103 is not tangled.

Another example of the hose storage unit 132 is provided with a hoist 141 equipped with a roller 140 so as to be freely moved in the up and down directions along the boom unit 103, and the hose 105 at the hoist port 141 When connecting and withdrawing, the hatch 141 rises along the boom stand 103, and when receiving it, it may descend along the boom stand 103 so that the hose 105 can be arranged.

Looking at the state of use of the vacuum cleaner hose control device for car washing to which the technology of the present invention is applied as described above is as follows.

In the initial state, the hose control device 110 mounted on the boom stand 103 is in a state in which the hose 105 is received and received in the hose storage unit 132, so the hose 105 is exposed to the ground or the boom stand 103 Since it is not organized and is kept in an orderly state, there is no interference with devices for surrounding car washing, there is no interference with users or vehicles, and there is a phenomenon in which the hose is damaged due to the entry and exit of the vehicle.

In this state, in the case of performing the indoor cleaning of the vehicle using the vacuum cleaner 100, when the vacuum cleaner 100 is operated, the drive motor 121 constituting the hose control device 110 mounted on the boom base 103 ) Is operated to withdraw the hose 105 that was stored.

Looking at this, the driving motor 121 is operated to rotate the motive gear 123, and the motive gear 123 is the lower gear 119 and the upper gear of the hose roller 116 installed on the upper side of the device body 113. 120) is rotated, and when the lower gear 119 and the upper gear 120 rotate, the lower roller 114 and the upper roller 115 connected thereto are rotated, so in the end, it is planted in the lower and upper rollers 114 and 115. The brush 118 penetrates into the corrugation 117 of the hose 105 and it becomes possible to withdraw the hose 105.

When the hose 105 is withdrawn as described above, the user can hold the suction nozzle 104 coupled to the tip of the hose 105 and suck foreign substances in the room to be cleaned. (If the 1050 end is sensed by the rear sensor 128, the drive motor 121 stops and stops without pulling out the hose 105 any more.

And, after the use of the vacuum cleaner 100 is completed, the user operates the driving motor 121 in reverse, or when the user is not in use for a certain period of time after leaving the seat, the controller reverses the driving motor 121. It is arranged by receiving the hose 105 drawn out during operation.

Again, when the driving motor 121 rotates in reverse, the lower and upper gears 119 and 120 are rotated in the reverse direction through the prime mover 123, and the lower and upper rollers 114 and 115 connected to the lower and upper gears 119 and 120 are reversed. The brush 118 planted in the lower and upper rollers 114 and 115 penetrates into the corrugations 117 of the hose 105 by rotating to accommodate the hose 105 in the opposite direction of the withdrawal, and is picked up and organized.

In the process of pulling out and receiving the hose 105 as described above, the hose 105 is stably pulled out and received by the funnel-shaped front and rear guides 125 and 126 mounted in the front and rear of the lower and upper rollers 114 and 115. Of course, since the front and rear sensors 127 and 128 provided in the front and rear guides 125 and 126 detect the ends of the suction nozzle 104 and the hose 105 to stop the driving motor 121, it is unintentionally excessive. It is possible to prevent the phenomenon of being stored and withdrawn.

And, the operation of the stopper 131 and the hose storage unit 132 constituting the hose storage means 130 when the hose 105 is received and withdrawn is as follows.

In the case of the stopper 131, when the end of the hose 105 is detected by the rear sensor 128 when the hose 105 is withdrawn, the drive motor 121 stops and the hose 105 withdrawal is stopped, but the intended value To prevent the stopper 131 from being pulled out any more when the hose 105 is pulled out (a phenomenon such as pulling the hose forcibly by the user), a spring is applied to the stopper body 134 connected to the boom stand 103. Since the wire 135 and the hose 105 are connected to the winding reel 133, which is built-in with, the pulling of the hose 105 is forcibly stopped when the withdrawal of the wire 135 is finished.

When the hose 105 is accommodated, the drive motor 121 operates and the wire 135 is applied to the hose 105 by the force that the winding reel 133 is to be wound up by the spring at the initial stage to lead the hose 105 By pulling, as well as providing ease of storage, the hose 105 is guided to stably enter the storage space 136.

The hose 105 accommodated in this way repeats the operation of being water-pressured in a neat state without being entangled in the receiving space 136 provided in the boom stand 103 and then withdrawing.

In particular, in the case of the present invention, the brush 118 is planted in the lower and upper rollers 114 and 115 constituting the hose roller 116 so that the brush 118 penetrates into the corrugation 117 of the hose 105 and is received and withdrawn. However, if the user pulls the hose 105 strongly, regardless of the rotation of the hose roller 116, the pull-out of the brush 118 is overcome and the hose 105 is pulled, so that the operation of the hose control device 110 It is possible to prevent phenomena such as disturbances or damage.

The present invention as described above has advantages such as improving space utilization and enabling efficient use while excluding the fear of safety accidents by arranging and arranging the hose of the vacuum cleaner so that there is no interference with surrounding car wash tools, users and vehicles.
