Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a towel dispensing device installed inside a toilet or the like, in particular, when a main switch is energized directly or indirectly, unused towels are supplied to the outside, This invention relates to an electric towel dispensing device that stores inside a loop-shaped used towel that is later wiped and soiled by a person.

Conventionally, as an electric towel dispensing device, the
No. 255 (US Pat. No. 3,797,902) is known. As is clear from the specification, this electric towel dispensing device includes a supply roller that supplies unused towels from an unused towel roll, and a used towel f:
A take-up roller that can be driven both in the winding direction of a used towel roll and in the opposite direction; a motor device that drives a supply roller and a take-up roller; and a motor device that drives and biases the supply roller in the supply direction. and a biasing device that is operated directly or indirectly by hand to drive and bias the take-up roller in the opposite direction of winding, and a predetermined length of the take-up roller from all used towel rolls. a deenergizing device that deenergizes the supply roller after unwinding the used towel; a deenergizing device that deenergizes the supply roller after supplying a predetermined length of unused towel; and a deenergizer that deenergizes the supply roller after a predetermined length of unused towel has passed; It consists of a timer and an energizing device that energize the winding roller, and a deenergizing device that drives the take-up when the take-up roller is exposed in a loop shape to the outside and de-energizes the whole length of the winding roller and then de-energizes it. ing.

Although this electric towel dispensing device is excellent in that it rationally drives the supply roller and take-up roller, it has a serious drawback in the opposite aspect. The disadvantage of chain 1 is that when the power source of this device is constructed from dry batteries, the dry batteries are consumed extremely quickly and the cost of replacing the dry batteries is high. In general, very few toilets are equipped with an outlet from which AC power can be drawn. Therefore, a dry basin is used as a power source for an electric towel dispensing device.

However, in the electric towel dispensing device according to the above-mentioned patent, since the used towel roll is rotated forward and backward by the take-up roller, the diameter of the used towel roll gradually increases, and its weight increases. As the size increases, the amount of power consumed for forward and reverse rotational movement becomes extremely large, which has the disadvantage of accelerating the consumption of dry batteries and increasing the cost of replacing them.

Also, as a second drawback, the above-mentioned U.S. Pat. No. 3,797,902
-5 as well as other manual towel force devices,
Since the used towel roll, I/, is placed above the unused towel roll, dirt particles adhering to the used towel will scatter and fall and adhere to the unused towel, causing the towel dispensing device to require cleansing. This was causing problems for Eigo.

Furthermore, as the third drawback of the above-mentioned U.S. Pat. No. 3,797,902, in order to change the loop length of the towel loop, there has been no method to change the rotation driving time of the supply roller or take-up roller, that is, the setting time of the timer. There wasn't. Therefore, the only way for a user to change the loop length is by switching a timer that has various built-in time widths, and even with this, it is difficult to arbitrarily and easily adjust the loop length to a desired length. .

Furthermore, to address the first drawback, a mechanism was adopted that made it unnecessary to reverse the used towel roll.

That is, the rotation of the supply roller in the supply direction and the rotation of the take-up roller in the take-up direction are essential and unavoidable movements in transferring the towel from the unused towel roll to the used towel roll. I learned that winding up and rotating in the opposite direction are not essential movements. On the other hand, dispensing a portion of the used towel from the rear of the towel dispensing device is necessary to improve towel economy in that the user only uses the front side of the loose towel and not the back side. Therefore, the main part of the present invention is that the used towel is fed out so as to reach the rear surface of the towel loop without reversing the used towel roll. That is, in addition to a take-up roller that rotates the used towel roll only in the winding direction, a feed row that rotates in the forward and reverse directions is provided, and a towel storage chamber is also provided.

Therefore, when winding up a towel loop, the entire length of the towel forming the loop is fed in the storage direction of the white collage.
・It is folded and stored in the storage chamber by rotating. or,
When using towels, the supply roller is rotated to supply unused towels to the front of the towel loop, and the take-up roller is rotated via an interlocking mechanism to separate the used towels in the storage chamber from the unused towels. Roll up the same length onto a used towel roll. At the same time, the feed roller is rotated in the feeding direction to feed the remaining amount of used towels in the storage chamber downward to form a back surface of the loose towel. In this way, the present invention provides an electric towel dispenser that can minimize battery consumption by feeding out the used towels folded inside the storage chamber without reversing the used towel roll. This is the realization of the given device.

Also, to address the second drawback, the used towel roll can be positioned below the unused towel roll, thereby eliminating the fall of dirt particles from the used towel.

Furthermore, by placing an unused towel roll on the towel tray, dirt particles flying up from the used towel are blocked by the lower surface of the towel tray. The invention thus aims to provide a clean motorized towel dispensing device.

Furthermore, to address the third drawback, if a towel loop is formed at the user's desired length when placing the unused towel roll on the towel tray and setting the towel, the length will be maintained from then on. To provide an electric towel dispensing device capable of adjusting a towel loop to an arbitrary length.

Set. When the transistor TR is turned on, the electric motor M1 moves the unused towel 1 as shown in FIG.
The supply roller 6 is rotationally driven so as to supply the sample in the direction of the arrow a. The rotation of the supply roller 6 rotates the gear G3 via the chain 23, and through the rotation of the take-up roller 20, the used towel roll 18 is rotationally driven in the direction of the arrow. As a result, two used towels that had been folded and stored in the storage room were found.
A part of 4 is sent in the direction of the arrow to the used towel roll 1.
The towel is wound up to the same length as the unused towel supplied in step 8. At this time, the used towels are not squeezed by the plate-shaped protrusion 28c, but are sent out from the sulin 28d, so the wrinkles of the towels are stretched out, and the bottom 28& of the storage chamber is curved so that they can be used. The finished towel 24 can be smoothly wound up. On the other hand, when the main switch Msw is pressed, the flip 70 knob FF2 is also set at the same time, turning on the transistor TR, the motor M2 rotates the feed roller 3o in the direction of the arrow, and the used towel folded and stored in the storage chamber is turned on. 24 in the direction of arrow C. therefore,
A towel loop 4o begins to be formed below the device by the unused towel 12 being supplied and the used towel container being fed out.

When the four parts 26a of the rotary disc cover rotate in the direction of the arrow and the actuator of the control switch csw is recessed into the recess 26a, the flip-flop FF is activated.

A reset signal is input to the electric motor Ml, and the electric motor Ml stops its rotation. Further, as a result of the used towel 24 in the storage chamber 28 being fed out in the direction of arrow C, when the tension switch TSW is turned on due to the tension of the towel, a reset signal is input to the flip-flop FF2, and the electric motor M
2 stops its rotation, and the towel loop 40 is completed downward as shown in FIG. 4(C). Furthermore, the on operation of the main switch MSW is performed by flip-flop FF3'.
i set, capacitor C! When I is charged and its potential reaches the potential R+a V/(RI2 +R+i) VC, the towel roof 4o is stopped until it reaches its completed state. During this time, the person can dry his or her hands or feet with a looped towel.

Therefore, the integrating circuit formed by the resistor R1□ and the capacitor C0 constitutes a timer.

The upper end potential of the capacitor C5 is the potential RIs V / (R
When exceeding tt +R+g)k, transistor TR8 is turned on, relay Ry is activated, and movable contacts MC,, MC,
are fixed contacts FC2 and FC as shown by dotted lines in FIG.

As described above, in this device, the used towel prisoner is fed out to form the towel loop 40 by taking out the used towel fL% that has been folded and stored in the storage chamber path, so there is no need for winding up. - There is no need to reversely shake the roller 20 and the used towel roll 18, and consumption of batteries such as dry cells can be suppressed. Also, if you want to change the towel loop length, use a rotating disc 2G with a different diameter.
This can be easily done by replacing the towel roll 2, or it can be done by freely adjusting the length of the loose towel formed at the bottom when loading a new, unused towel roll 2.

FIGS. 5A and 5B show a case where the final end 24a of the unused towel roll 2 is completely wound up when it is lost. When a person presses the main switch MSWk, if the remaining length of the unused towel is shorter than its supply length, the final end 24a of the towel hangs downward. In this state, a person wipes his or her hands, but after a certain period of time, the motor M is activated as shown in FIG. 5(A).

starts pulling up 24 used towels. As shown in FIG. 5 [F]), the drawn used towel is stored in the storage chamber 28 in a folded manner, but when the final end 24a of the towel passes the end switch ESW, the timer ”
-The ESW actuator opens, the voltage supply from the batch IJ-BT is cut off, and the motor M2 stops. Therefore, regardless of whether the under switch USW is opened or closed, by cutting off the power, the unsightly final end 24 of the towel can be removed.
(a) The entire body is drawn into the device.

FIG. 6 shows another embodiment of the circuit including the electric motor NLk. This circuit functions to wind up the final end 124a'i of the towel stored in the state shown in FIG. 5(B) onto the used towel roll 18. The movable contacts MC3 and MC4 are connected to normally fixed contacts FC, FC7, respectively. Therefore, when the end switch ESW is cut off, the motor r
Mountain +M2 reaches and stops, and the state shown in FIG. 5(B) appears. The person who discovered this condition replaced the movable contacts MC3, MC with the fixed contacts FC.

When connected to FC8, motor M1 is connected to battery BT.
A voltage of ■ is applied to the supply roller 6 and the take-up roller 2.
0, and as a result, the used towel roll 18 rotates in the direction in which the used towel 24 is wound up. Therefore, all the used towels 24 in the storage chamber 28 are wound up on the used towel roll 18. To return to the original state, moveable contacts MC, MC, all fixed contacts FC, FC, F
C, take out the used towel roll 18i outside, and load the unused towel roll 2 into the device.

As described in detail above, the present invention prevents the reverse rotation of the used towel roll by feeding the used towel folded into the storage chamber downward by the feed roller, thereby suppressing battery consumption. It is thus possible to provide a motorized towel dispensing device in which the loop length can be adjusted very easily according to the user's wishes, and which also prevents dirt particles from contaminating unused towels.
