Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention particularly relates to an improvement of a coin control device for a so-called coin-operated washing machine, which is operated by inserting a coin.

BACKGROUND ART A conventional washing machine of this type has a top plate 2 provided at the top of a washing machine main body 1, as shown in FIG.
An operation box 3 in which various control devices (not shown) are housed is arranged behind the control box 3, and a panel 4 is provided on the front surface of the operation box 3. A coin control device 6 is disposed in a partially cut-out portion of the panel 4 so as to be rotatable around the fulcrum 5. 7 is an input slot provided in the coin control device 6, and 8 is a key.

Inside the coin control device 6, a coin sorting mechanism, a coin switch (not shown), and the like are provided. Further, a coin box 10 for collecting coins is provided in a space 9 below the coin control device 6 of the operation box 3. When collecting coins, first turn the key 8 in the P direction to remove the key 8, turn the coin control device 6 in the Q direction, insert your hand as shown, take out the coin box 10, and collect it. It was configured to do this.

Problems to be Solved by the Invention In such a conventional configuration, when collecting coins, the coin box 10 must be taken out with the coin control device 6 wide open.
The coin control device 6, which is wide open, incorporates electrical components such as a coin sorting mechanism and a coin switch, and there is a risk of electric shock if the user accidentally touches the electrical components when collecting coins.

In order to solve the above problem, JP-A-56-143196
There is a coin-operated washing machine shown in the publication. This coin-operated washing machine had a coin control device installed at the rear of the panel so that only the coin box could be inserted and removed from the front of the panel, and the coin sorting mechanism was not exposed when coins were collected.

However, in the coin-operated washing machine mentioned above, the coin box is located at the front of the panel, so even a third party can easily know the position of the coin.
There was a problem in that the coins in the coin box were easily stolen.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to improve the workability of collecting coin boxes in a coin-operated washing machine in which the position of the coin box cannot be confirmed from the outside.

Means for Solving the Problems In order to achieve this object, the present invention covers the open surface of the operation box integrally formed on the upper part of the washing machine main body with a panel having an opening, and also covers the operation box from the opening. In a coin-operated washing machine that houses a coin control device having a coin sorting mechanism and a coin box, the coin control device stores and holds a coin box and has an opening in the front for inserting and removing the coin box. A box-shaped cover is provided, and two rows of vertically long parallel elongated holes are formed in both side walls of the cover, and each of the elongated holes has an arm fixedly protruding from the inner surface of the panel. is inserted, and the coin control device is allowed to float within the vertical sliding range of the arm relative to the elongated hole, and the longitudinal dimension of the elongated hole is made to float to a minimum height at which the coin box can be inserted and removed. When the coin control device is in the lowered position, the opening for inserting and removing the coin box is located below the opening in the panel.

Operation According to the above configuration, since the coin control device is pivoted by the arm inserted and fitted into the elongated hole of the cover of the coin control device, the coin control device can reliably and smoothly slide in the vertical direction. This eliminates problems with jamming and incomplete insertion, and when the coin control device slides up, only the opening for taking out the coin box is exposed on the panel surface, so the coin sorting mechanism and the coin selection mechanism inside the coin control device are eliminated. The coin switch part is not exposed, eliminating the need for hand contact when collecting coins.

Embodiments Embodiments of the present invention will be described below with reference to FIGS. 2 to 5. In the figure, 12 is a main body, on which a top plate 13 is provided, and an operation box 14 is integrally formed behind this top plate 13. Operation box 14
Various control devices (not shown) are provided inside the device, and a panel 15 is provided in front of the device.

Reference numeral 16 denotes a coin control device, which includes an input slot 17, a coin sorting mechanism 18, and a coin box 19. The coin sorting mechanism 18 and the coin box 19 are covered with a box-shaped cover 20 that is open on the front side on the input port 17 side, and this cover 20 is fixed to the coin control device 16. Further, the coin control device 16 is locked to the panel 15 by a lever 22 of a key 21.

A spring receiving portion 24 is provided in a recess 23 at the bottom of the operation box 14 at the rear of the top plate 13.
One end side of the elastic body 25 is inserted into this.
Cover 2 covering the coin control device 16
A spring receiving portion 26 is provided on the lower surface of the spring 0, and receives the other end side of the elastic body 25 described above.

In the above configuration, the operation will be explained next. First, as shown in FIG.
When inserted, the coin 27 enters in the direction of the arrow S, gives a signal to the coin control device 16, falls in the direction of the arrow T, falls into the coin box 19, and accumulates therein. When a certain amount has accumulated, turn the key 21 in the direction of arrow P as shown in FIG. By doing so, the key 21 is unlocked, and the elastic body 25 provided between the bottom surface of the cover 20 and the recess 23 of the operation box 14 pushes up the cover 20 in the direction of arrow U.
The entire coin control device 16 protrudes from the panel 15 surface. After the coin control device 16 floats in the direction of the arrow U, the coin box 19 is pulled out in the direction of the arrow R through the opening 28 provided on the front surface of the cover 20, and the coins 27 are collected. After collection, coin box 19
is pushed into the cover 20, the coin control device 16 is pushed in from above, and the lock is locked by locking the key 21, and the coin collection operation is completed.

Next, the main parts will be explained in detail. On both side walls of the cover 20, there are two long holes 20a,
20b is provided, and the panel 15 has a long hole 20b.
An arm A29 and an arm B30 are fixedly arranged with mounting screws 31 and 32 at positions corresponding to a and 20b. This arm A29 and arm B30
are inserted and fitted into the elongated holes 20a and 20b of the cover 20, respectively, and the coin control device 16 with the arm A29 and the arm B30 pivotally supported,
The longitudinal dimension L of the elongated holes 20a and 20b of the cover 20, which slide up and down within the range of the elongated holes 20a and 20b, is such that the coin box 19 when the coin control device 16 is slid and floated in the direction of the arrow U is It is set to the minimum height l that can be pulled out from the opening 28.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the coin control device can be operated reliably and smoothly since the coin control device is pivoted by the arms inserted and fitted into the two rows of long holes in the cover of the coin control device. It performs sliding motion in the vertical direction, eliminating jamming and incomplete insertion, improving work efficiency when collecting coins. In addition, when the coin control device is slid and floated, only the opening for removing the coin box is exposed on the panel surface, so the coin sorting mechanism and coin switch part in the coin control device are not exposed, and the coin selection mechanism and coin switch are not exposed. A coin-operated washing machine that is excellent in preventing theft can be provided because the coin box part is not exposed from the panel surface and cannot be seen except when collecting coins.
