Description

[Detailed description of the invention] The present invention relates to a device for holding objects to be cleaned in a rotary washing machine, and in particular, it facilitates the operation of loading and unloading the objects to be washed into and out of the holding frame for the objects to be washed. By effectively utilizing the horizontal rotation of the holding frame, the object to be cleaned that is previously held in the holding frame is always automatically and reliably locked, regardless of changes in its size, type, shape, etc. This is designed to completely prevent objects to be cleaned from shaking or falling off during work.

Hereinafter, the configuration of the present invention will be described in detail based on the illustrated embodiments. Figures 1 to 4 show the entire rotary automatic washing machine according to an application example of the present invention, and 1 is made of metal. The rigid mounting frame is surrounded by foreign metal plates to form a substantially sealed rectangular cylindrical machine casing.

Reference numeral 2 denotes a cylindrical compartment installed and fixed in the road half of the machine casing framed by the frame 1, which functions as a cleaning chamber, a rinsing chamber, or a dehydration (drying) chamber, respectively, depending on the order of operation of the washer.

This compartment 2 has a window 3 on a part of its circumferential side, and the window 3 is further communicated with a hot air vent 4 opened at a position closer to the top of the machine housing.

Further, the compartment 2 is in communication with the hot air inlet tube 5 integrally formed near the center of the top of the machine housing, and therefore the compartment 2 is substantially sealed, but the compartment 2 itself is built into the machine housing. As a result, the rotating body, the holding frame for objects to be cleaned, etc. stored in the compartment 2 as described later are enclosed in a so-called double wall structure, which prevents heat dissipation and liquid leakage. In addition, it can provide effects such as sound insulation.

Reference numeral 6 designates a collection port for cleaning liquid and rinsing liquid, which is opened in the center of the funnel-shaped bottom of the compartment 2, and 7 represents a door that opens and closes the window 3 of the compartment 2.

Furthermore, the following mechanism is built into the substantially lower half of the square tube-shaped machine casing.

That is, 8 and 9 are a cleaning liquid discharge pump and a rinsing liquid discharge pump that are installed in parallel below the compartment 2, 10.11 are a cleaning liquid storage tank and a rinsing liquid storage tank that are also installed in parallel below the compartment 2, and 12 is the cleaning liquid pump 8
13 is a rinsing liquid suction passage that also communicates between the rinsing liquid pump 9 and the tank 10, and the rinsing liquid sucked through the suction passage 13 is transferred to the pump. 9 and a large number of rinsing liquid injection nozzles 14 piped in the compartment 2 are connected to each other through a rinsing liquid discharge passage 15, and the pump 9 sprays the rinse liquid from the nozzles 14 onto the object A to be cleaned.

Similarly, the cleaning liquid injection nozzle 16 and the cleaning liquid discharge pump 8 of the piping in the compartment 2 are communicated with each other through a cleaning liquid discharge passage 17, and the pump 8 is also used to direct the cleaning liquid from the multiple nozzles 16 to the object A to be cleaned. is ejected.

In other words, the circulation system for the cleaning liquid and that for the rinsing liquid are piped as completely separate systems, which helps to prevent the two liquids from mixing together.

Incidentally, by inserting a finger into each of the nozzles 14 and 16 through the window 3 of the compartment 2, the direction in which the liquid is ejected can be easily changed and adjusted.

Reference numerals 18 and 19 denote a cleaning liquid discharge passage and a rinsing liquid discharge passage that communicate with the bottoms of both tanks 10 and 11 separately, and both are normally closed by opening/closing cocks 20 and 21 that can be operated from the outside of the machine housing. However, since curved overflow passages 22 and 23 that straddle the cocks 20 and 21 are communicated with each other on their way, excess amounts of each liquid are discharged from these passages 22 and 23 during operation of the washer.

In this case, in the illustrated example, the overflow passages 22.23 are made of transparent vinyl pipes so that the amount of liquid stored in each tank 10.11 can be visually confirmed from the outside, but this is because the passages 22.23 are common to both liquids. Both discharge channels 18.1 as one of the
9, and a level meter for visual confirmation of the storage amount of each liquid may be attached completely separately from this.

24 is a heat exchange cylinder inserted in the middle of the cleaning liquid discharge passage 18 in a communicating manner, and 25 is a make-up water introduction passage into the rinsing liquid storage tank 11. The heat of overflowing cleaning fluid is used to automatically raise the temperature of make-up water.

Reference numeral 26 denotes a float valve for detecting the amount of rinsing liquid stored in the rinsing liquid storage tank 11, which automatically opens and closes the make-up water introduction path 25.

Reference numeral 27 denotes a cleaning water supply line which is piped horizontally into the upper part of both tanks 10 and 11, and is connected to the water supply etc. through hoses together with the make-up water introduction line 25.

Further, reference numerals 28 and 29 denote a cleaning liquid recovery passage and a rinsing liquid recovery passage, which are also connected to both tanks 10 and 11 separately, and both circulation passages 28 and 29 further have a communication passage 30 that communicates with each other in a collective intersecting manner. It is also in communication with the recovery port 6 of the compartment 2 through the opening.

31 is a switching valve built in this communication passage 30, which is automatically rotated by, for example, 90 degrees by a cylinder 32;
A cleaning liquid recovery path 28 or a rinsing liquid recovery path 29 is selectively communicated with the recovery port 6 of the compartment 2.

33 is a heater (burner, boiler, etc.) that raises the temperature of the cleaning liquid and rinsing liquid in both tanks 10 and 11, and is installed at a position directly adjacent to the rinsing liquid storage tank 11 in approximately the lower half of the machine housing. ing.

Immediately before the washing machine is activated, the temperature of both liquids is raised by the heater 33, and the rinsing liquid changes from water to hot water.
Acidic, neutral, and other types can be selected and used.

) will be suitably melted.

Reference numeral 34 designates a furnace tube installed as an introduction into both tanks 10 and 11, and 35 designates an exhaust pipe connected to the extended tip of the furnace tube 34, which is adjacent to the cleaning liquid storage tank 10 side and connected to the machine housing. It is fixed in an upright manner along the outer surface.

Reference numeral 36 denotes a heat insulating cylinder that covers the exhaust pipe 35, the top of which is closed, and the bottom of which is opened for introducing outside air.

In the mutual gap between the heat retaining tube 36 and the exhaust pipe 35, preferably spirally continuous fins 37 having an umbrella-shaped cross section are interposed, so that the exhaust heat of the exhaust pipe 35 is effectively utilized. It is designed to easily turn the outside air introduced from below into hot air in the process of spiraling upward.

Reference numeral 38 denotes a hot air introduction guide tube that communicates and connects the top of the heat insulating tube 36 and the hot air introduction tube 5, and as is clear from FIG. However, in order to face the position near the rotation center of the rotating body, which will be described later,
The hot air is automatically and forcibly sucked into the center of the compartment 2 from above by the negative pressure generated at the center of the rotating body as it rotates horizontally.

On the other hand, since the hot air outlet 4 is arranged as an opening on the circumference of the rotation locus of the rotating body, the residual moisture present in the object A to be cleaned is efficiently removed from the outlet 4 along with this hot air. It is well discharged and is also instantly swept away through the window 3 when the door 7 is opened when the object A to be cleaned is taken out.

Although not shown, there is a cylinder 3 on the outer surface of the machine casing.
2, motor, pump 8, 9, etc. control panel,
An operation panel is attached, and the operation panel also has a work start button, an emergency stop button, and cleaning/rinsing/dehydration (drying).
It is equipped with various timers, etc.

Further, in the center of the compartment 2, a rotating body consisting of a vertical rotating shaft 39 and rotary blades 40 as described below is installed so as to be rotatably driven by a motor.

That is, in FIGS. 5 to 7 showing this, reference numeral 41 indicates an upper rotating shaft to which a rotating flange 42 is fixed at the lower end, 43 indicates a lower rotating shaft to which a rotating flange 44 is also fixed to the upper end, and 45
is an intermediate rotating shaft whose upper and lower ends are respectively flanged and detachably bolted to the plane rotating flanges 42 and 44, and these three parts are divided in advance and are detachably connected and integrated on the same axis. By forming the rotating shaft 39 from the shaft, it is expected that it will be easier to assemble and disassemble, and that the force applied to the brake will be dispersed.

46 is a motor for driving the rotating body, 47 is an electromagnetic brake for braking, and 48 is a speed reducer, all of which are installed in a retracted manner at the top of the machine housing, making maintenance, inspection, and replacement easy. Simplification has been attempted.

The upper rotating shaft 41 is penetratingly supported in the center of the machine casing, and the lower rotating shaft 43 is supported by a support base 50 fixed to the mounting frame 1 via a plurality of pillars 49.

In this case, since a plurality of pillars 49 are erected to support the lower end of the rotating shaft 39, the collection port 6 can be easily formed in the center of the bottom of the compartment 2, and the upper end screw portion of each pillar 49 can be easily formed. is inserted into the elongated hole 51 facing in the radial direction of the support base 50,
Since the rotary shaft 39 is removably fixed by screwing the tightening nut 52, the erroneous inclined position of the rotating shaft 39 during assembly can be easily adjusted to the correct vertical position by moving the support base 50.

Note that 53 is a rotating cover for preventing liquid immersion holes in the bearing portion of the rotating shaft 39, and rotates integrally with the rotating shaft 39.

The rotary blades 40 are arranged in an upper and lower pair having a large-diameter annular shape, and are removably bolted to each rotary flange 42, 44 of the rotary shaft 39 via a plurality of arms 54 extending in the centripetal direction.

Integrating such a large-diameter annular rotary blade 40 into the rotary shaft 39 is useful for holding a large number of objects A to be cleaned.

Reference numeral 55 denotes a plurality of (eight in the example shown) holding frames for objects to be cleaned arranged at equal intervals around the circumference of the rotary blade 40, each of which is made of metal wire rods as shown below. It is assembled from a fixed frame 56 and a movable hook frame 57.

That is, in FIGS. 8 to 10 showing the overall shape of this frame, the fixed frame 56 will be described first. 56a is integrally formed so that it is approximately U-shaped when viewed from the front and approximately U-shaped when viewed from the side. It is a curved narrow rod, and the lower part of the rod extending forward is a locking hook portion 56b bent at an acute angle.

58 is the upper and lower part 2 fixed to the vertical rear part of the narrow rod 56a.
A total of 4 vertical mounting tubes forming a pair, 59 is a narrow rod 56
56 C is a narrow rod, and 56 C is a reinforcing bar fixed horizontally to the top of 56 a. 56 d is a reinforcing bar, which is also fixed to the bottom of 56 A, and 56 C is a narrow rod. A pair of horizontally suspended front and rear reinforcing bars, 56 e is a narrow bar 56 a
A pair of left and right reinforcing bars fixed to the lower corners of the
f is a wide rod curved into a U-shape when viewed from the front;
By fixing both upper and lower ends to the narrow rod 56a, the entire fixed frame 56 is generally shaped like a model.

60 is a pair of left and right vertical supports fixed to the vertical rear part of the wide rod 56 f, and various adapters 61 formed by bending from the metal wire rod are inserted and engaged in a removable manner. Use accordingly.

Such a fixed frame 56 is provided with a pair of upper and lower rotary blades 4.
to the corresponding number of support cylinders 52 protruding from the circumference of 0;
The vertical mounting cylinder 58 is fitted from above and removably fixed by a bolt 63 screwed into the screw hole of the support cylinder 62.

In this case, out of a total of four mounting pipes 58 and their corresponding support pipes 62, for example, any two mounting pipes 58 and their support pipes 62 are lengthened, and the remaining two mounting pipes 58 and their support pipes are lengthened. By shortening the tubes 62 and making their lengths different in advance, first, the long mounting tube 58 is externally fitted and locked to its support tube 62, and then the short mounting tube 58 is attached to its support tube 62. It is preferable to make it so that it can be fitted externally to the outside, so that it can be easily positioned at the time of installation.

On the other hand, when viewed from the front, the movable hook frame 57 has an approximately U-shape that is slightly narrower than the narrow rod 56a of the fixed frame 56, and when viewed from the side, the movable hook frame 57 is integrated into an overall hook shape that is approximately inverted. The free end of the upper part of the curved shape is connected to the hook part 56 of the fixed frame 46.
A locking hook portion 57 bent at an acute angle opposite to b
It is set as a.

57 b is a pair of left and right horizontal pivot portions extending laterally outward at the lower proximal end of the hook frame 57, and 57 C is a pair of horizontal pivot portions extending laterally outward in parallel with the pivot portions 57 b above the pivot portions 57 b. A pair of left and right stopper protrusions 57 d are fixed to the hook frame 57 and are a pair of left and right reinforcing bars.

Such a movable hook frame 57 is made by forcibly deforming the metal wire rod with fingers so as to narrow the width, and then deforming the pivot portion 57 of the movable hook frame 57.
b is detachably and rotatably pivoted to the fixed frame 56 by loosely engaging the tube 59 with the horizontal receiver of the fixed frame 56 from the inside.

The above deformation is made possible by the elastic force accumulated in the movable hook frame 57 itself due to the bending of the metal wire rod,
Therefore, if you release your finger after inserting the follower into the cylinder 59, the pivot portion 57
b, the receiver is locked in a manner that cannot be removed from the cylinder 59.

The operation for extracting the pivot portion 57b from the tube 59 can be performed in the same manner as described above.

In particular, when the movable hook frame 57 and the fixed frame 56 are assembled, the pivot point of the hook frame 57 is set at a position that is offset downward from the center of gravity of the hook frame 57 itself. As a result, when the object to be cleaned A is held in the holding frame 55 and rotated horizontally together with the rotating body, the movable hook frame 57 is rotated downward and automatically rotates. It is designed to generate a biasing force to hold and lock the object A to be cleaned from above.

Furthermore, the object to be cleaned A is held so as to be placed on the fixed frame 56, and the front lower part thereof is locked by the hook part 56b of the narrow rod 56a; Hook part 57 a of movable hook frame 57 on the front upper part of A
When the hook frame 57 is set and horizontally rotated so as to be temporarily locked, the special setting of the pivot point allows the downward movement of the movable hook frame 57, especially at the hook portion 57a at the free end. The object to be cleaned A is automatically turned upside down and pressed down in a wedge shape from above, and the fixing frame 56
In combination with the middle hook portion 56b, the object to be cleaned A is clamped and fixed from both the upper and lower sides. The front surface of the object A to be cleaned is pressed against both hook portions 56b and 56a by the force, so that it is held in a completely locked state without wobbling.

The fact that the receiver tube 59, which receives the pivot portion 57b of the movable hook frame 57, is fixed to the fixed frame 56 as an upper and lower pair is as follows.
The purpose is to make it possible to change the pivot point of the hook frame 57 depending on the size and type of the object A to be cleaned, and FIGS. 8 and 9 show the movable hook frame 5 to accommodate the large object A.
7 is shown in a state in which the hook frame 57 is pivotally attached to the tube 59 in the upper receiver, and FIG.

Incidentally, as long as the above purpose is maintained, the number of tubes 59 in the receiver may be further increased, and the movable hook frame 57 can be slid up and down with respect to the fixed frame 56, and the slide can be fixed at a desired position. However, the same effect can be achieved.

Various kinds of bent adapters 61 made of metal wire rods are prepared to accommodate changes in the type and shape of the object A to be cleaned, for example as shown in FIG. The adapter 61 may be inserted and locked in a removable manner into the cylinder 60, thereby also restraining the circumferential surface of the object A to be cleaned by the adapter 61, thereby further improving the complete locking of the holding state.

In addition, when the rotating body is stopped in the state where the movable hook frame 57 is pivotally attached to the fixed frame 56, the hook frame 57
This means that the stopper protrusion 57C, which extends sideways from the hook frame 57, hits the narrow rod 56 of the fixed frame 56 from behind due to its own weight. Since the hook frame 57 is prevented from rotating meaninglessly downward, the object to be cleaned A is
When putting in and taking out the object A, it is sufficient to rotate the movable hook 57 slightly to open it from the fixed frame 56, and the work of holding the object A to be cleaned can be carried out easily and efficiently.

In the illustrated example, the object to be cleaned A is inserted and held into the holding frame 55 from the bottom side thereof.

The washing machine configured as described above can automatically and continuously perform the three steps of washing, rinsing, and dehydrating (drying) the object A to be washed in one cycle as follows.

That is, to the holding frame 55 of the rotating body erected in the compartment 2,
If you hold all the objects to be cleaned A with your fingers inserted through the window 3 and then press the work start button, the objects to be cleaned A will be rotated together with the rotating body by the motor 46.
First, the cleaning liquid discharge pump 8 is automatically started.

Therefore, the cleaning liquid passes through the distribution system to a large number of nozzles 1.
6, the water is evenly sprayed onto the object to be cleaned A which is rotating at a low speed, and the object to be cleaned A is cleaned for a certain period of time set in advance by a cleaning timer.

The cleaning agent-only liquid is circulated and collected into the cleaning liquid storage tank 10 via the collection chamber 6 → communication path 30 → recovery path 28 in the compartment 2 .

After cleaning is completed, the cleaning liquid discharge pump 8 automatically stops.
After a while, the rinsing liquid delivery pump 9 is then automatically started.

Then, the rinsing liquid is sprayed through the distribution system onto the object A, which continues to rotate at a low speed, and the object A is rinsed for a period of time set by the rinsing timer.

In this case, the rinsed liquid is automatically transferred from the recovery channel 6 to the recovery path 29 by the automatic switching operation of the recovery system by the switching valve 31.
The rinsing liquid is returned to the rinsing liquid storage tank 11, but considering that in this washing machine, the rinsing liquid at the beginning of rinsing contains residual cleaning liquid in the compartment 2, etc., this is collected into the rinsing liquid storage tank 10 side. As shown, rinse liquid discharge pump 9
The switching valve 31 switches compartment 2 only during a certain period of time after the engine starts.
The recovery port 6 is set to communicate with the cleaning liquid recovery path 28.

When the rinsing process is completed, the rinsing liquid discharge pump 9 also automatically stops.

During both cleaning and rinsing, the object to be cleaned A is
is rotated at a low speed, both liquids are evenly distributed to every corner of the object A, and by continuously spraying a large amount of the heated liquids, the object A is completely washed by the time the rinsing is completed. It will itself have heat.

After the rinsing liquid discharge pump 9 is stopped, the rotating body and the object to be cleaned A are automatically shifted to high speed rotation, and dehydration (drying) is performed for a predetermined time set in advance by the dehydration (drying) timer.
Work is carried out.

In this case, the object A to be cleaned is subjected to its own heat, high-speed rotational centrifugal force, and hot air generated using the heater 33 as a heat source due to the suction pump action of negative pressure accompanying high-speed rotation. A synergistic effect with the automatic introduction into the compartment 2 results in complete drying.

After the motor 46 is stopped, the switching valve 31 is automatically returned, and preparations are made for switching to the initial communication state between the recovery port 6 and the cleaning liquid recovery path 28.

These three steps are considered to be one cycle, and multiple items to be cleaned A are automatically and continuously processed at once. For example, by setting the rinse timer or dehydration timer to zero, the washing machine can be It is also possible to use it only for cleaning, or only for cleaning and rinsing.

The items to be cleaned A are primarily plastic food and drink containers, such as supermarket shopping baskets, bread boxes, bottles and egg storage boxes, but metal parts and other items may also be used. Of course.

As described above, the present invention serves as an object holding device for a rotary washing machine, in which the object holding frame 55 made of metal wire rods is attached to the fixed frame 56 that can support at least the lower part of the object A.
and a movable hook frame 57 that removably engages the object to be cleaned A held by the fixed frame 56 from above, and the fixed frame 56 is attached to the circumference of a rotating body that is horizontally rotated. , the movable hook frame 57 is pivotally attached to the fixed frame 56 so as to be rotatable about the horizontal axis, and the pivot point ζ is set at a position below the center of gravity of the movable hook frame 57 itself, so that the fixed frame A movable hook frame 57 that forcibly rotates the object to be cleaned A, which is held in advance by the movable hook frame 56, as the rotating body rotates horizontally.
Because it is structured so that it can be automatically locked by the wedge action of This is completely prevented by the wedge action of the movable hook frame 57 that locks the movable hook frame 57. Moreover, it is sufficient to temporarily lock the hook part 57a at the free end of the movable hook frame 57 to the object A to be cleaned from above, and the rest is done during the work. Since the object to be cleaned A is automatically locked by the movable hook frame 57 that rotates downward, the work of holding the object to be cleaned A is significantly simplified.

This means that by inserting your hand through the limited window 3 of the painting room 2,
This means improved efficiency in loading and unloading a large number of objects A to be cleaned into and out of the holding frame 55 of the rotating body.

Furthermore, the holding frame 55 assembled from the fixed frame 56 and the movable hook frame 57 is made of metal wire rods, so it is extremely lightweight, and therefore helps to minimize rotational resistance of the rotating body. This does not impede the flow and spraying of the liquid onto the object to be cleaned A held in the area, and therefore it is possible to uniformly apply cleaning and rinsing effects to every corner of the object to be cleaned.

In particular, since the movable hook frame 57 is set so that its pivot point can be changed in the vertical direction with respect to the fixed frame 56, for example, as in the illustrated embodiment, the fixed frame 56
By replacing the movable hook frame 57 into the cylinder 59, the multiple horizontal receivers above can accommodate changes in the size and type of the object A to be cleaned, while using the same set of fixed frame 56 and movable hook frame 57. The object to be cleaned A can be reliably held and fixed at all times while quickly responding to the situation, and even in this case, the object A to be cleaned is still subject to the wedge action of the movable hook frame 57 as described above.

If various kinds of the above metal wire rod adapters 61 are also used, it will be easier to deal with various objects A to be cleaned, and the holding and fixing thereof will be even more stable, so it can be said to be a very useful idea.
