DESCRIPTION

Built-in dishwasher with increased load capacity

The present invention relates to a built-in dishwasher with increased loading capacity.

The built-in dishwashers installed inside modular kitchen structures which, for purely aesthetic reasons, are hidden by a front panel (identical to the other front panels of the modular structure) which is coupled to the loading door of the machine are already known and widely used.

This purely aesthetic requirement entails great limitations in the depth of the machine and limits its performance.

The dimensions of the machine are not only limited in height, to allow it to be housed under a working surface of the modular structure, and in width (typically 600 mm, sometimes 450 mm) to respect the modular characteristics of the structure.

It is also necessary to limit the depth dimension of the machine (it is understood that it means the horizontal length or distance of the front of the machine from a rear juxtaposition wall) to allow the coupling of the front loading door with a masking panel the which is aligned with the other front panels of the structure.

Since, typically, the depth dimension of the modular kitchen structures is 570 mm, it is therefore necessary that the depth dimension of the dishwashers is not more than 550 mm and, preferably, 540 mm to allow overlapping on the loading door of a masking panel with a thickness of not less than 20 mm (generally between 20 and 30 mm).

The overall volume of the machine is, in this way, limited by these three parameters: height, width, depth and, much more, the load or useful volume of the washing chamber, which must be housed between insulated walls of a certain thickness and must leave a certain free volume to accommodate the electrical, mechanical and hydraulic members of the machine, it is necessarily less than the available volume.

Many efforts have been made to improve the relationship between the payload volume and the overall dimensions of the machine, within the dimensional limits defined by the embedded modular structure.

However, the ever-increasing demand for a greater load capacity, for some users, makes these efforts ineffective and would require the development and production of new machine models, incompatible with a built-in modular structure or, if compatible, for example with a width 90 cm modular, substantially different from current production.

The production of such different models, to meet different types of user, would entail fixed plant costs, operating costs and costs of substantial materials to activate the different production lines which it is desirable to avoid.

Document GB2189136A discloses a dishwasher comprising the particularities of the preamble of claim 1.

The present invention solves the problem of preventing the activation of different production lines with simple dimensional variations which involve only the structure of the loading door of a conventional built-in dishwasher (and only removable internal accessories) and allows, with fixed investments and minimum additional operating costs, two different dishwasher models to offer to the market: one conventional built-in installed in a modular structure and a second innovative with increased payload volume, even for embedded installation but, in this case "in sight" with the possibility of coordinating the appearance of the machine with that of the modular structure in an aesthetically satisfactory way.

In addition, the invention allows the introduction into the machine of recently proposed constructive teachings which further increase its load volume and significantly improve its ergonomic characteristics.

These results are obtained with a dishwasher as defined in the appended claims.

To adopt this constructive strategy, which substantially foresees an increase in the volume of the loading door, obtained with a greater depth of it, in which an embedded space is formed, open to the inner face, of greater depth, is It is necessary to solve the technological problem of reconciling the intrinsic limits of drawing operations with this new requirement.

This aspect, as well as the features and advantages of the invention, will become clearer from the following description of a preferred embodiment and its variants, made with reference to the accompanying drawings in which:

20 - Figure 11 is a schematic front-to-back sectional view of the automatic closing kinematics of the discharge hatch of the measuring / dispensing device of Figure 9, locked with the opening of a lid of the measuring / dispensing device .

To better understand the invention, it is advisable to consider first of all the structure of a loading door for a conventional concealed concealed dishwasher, as depicted in the exploded perspective view 25 of Figure 1. The door is formed from an external front panel 1, generally made from a metal plate (or, alternatively, molded in plastic), with the edges folded double to form a reinforcement frame 2, with a C-shaped section, the which is coupled, through connecting screws, with a flat perimeter fin 3 of a cladding or door panel 4, generally made of stainless steel, conveniently formed by deep drawing to form fin 3 and a frame with one side

30 upper 5, lateral sides 6, 7 and a lower side 8.

In the lower part, the counter door panel is embedded forming a recess and forms a housing 9 which increases the useful volume of the washing chamber.

Clearly, the depth of the recess 9 cannot be greater than the sum of the depth H1 of the frame 2 of the front panel and the depth H2 of the frame of the counter door and, in general, is somewhat less to allow

35 thermal and acoustic insulation (through the interposition of suitable insulating materials) of the door panel 4 from the front panel 1.

In the intermediate space between the front panel 1 and the upper part of the counter door 4, control devices, a keyboard and, sometimes, luminous displays, indicated globally with 10, are housed and accessible on the upper side of the frame 2.

In the intermediate space between the front panel 1 and the upper part of the counter door is also housed a device 11 for measuring / dispensing detergent and additives, accessible from the inner side of the loading door.

The loading door is hinged at the bottom of the dishwasher body through support arms 12, 13 to take a vertical closed position or a substantially horizontal open position.

45 When the loading door is closed, the counter door frame penetrates the loading opening of the machine body and is tightly coupled to the water, along line 14 represented by a broken line, with a gasket suitable for the loading opening of the machine body, protruding over the walls of the washing chamber.

The lower side of the counter door frame is generally also equipped with a seal 50.

In order to minimize the projection of the joint in the loading opening, it is necessary that the door frame has external walls 5, 6, 7, 8 that are substantially perpendicular to the plane of the door panel.

This limits the depth H2 of the counter door frame obtained by drawing, to 20-30 mm.

A deeper drawing, certainly, would take the material of the counter door beyond its elastic limit and consequently lead to breakage.

On the other hand, the recessed recess 9 can have inclined perimeter walls, which allows a much deeper drawing, however, still limited by the interference that would exist between the base of the recess 9 and the front panel.

In this conventional structure there are two substantial limits.

The recess 9 of the counter door, which is limited in its depth and vertical development, increases the payload capacity moderately.

In addition, the loading operation of detergent and additives is not ergonomic because it requires notoriously the placement of the fully open loading door, practically horizontal and very close to the ground, forcing the user to lean to perform the operation. To avoid these inconveniences, it has recently been proposed (European patent N 01 830 512 8) to extend the deep drawing forming a recess 9, substantially for the entire height of the counter door, obtaining a larger capacity housing and housing the measuring / dispensing devices of detergent and additives in the volume between the front panel and the upper side of the door frame. At the same time, a measuring / dispensing device has been proposed, with a loading cover separated from the discharge shutter and open on the upper face of the counter door frame, to allow the loading of detergent and additives with the loading door in a practically vertical position.

Also in this case, however, the increase in the useful volume of the washing chamber is insufficient to meet the ever increasing demand for a larger capacity, because the depth of the recess of the counter door is limited.

This limitation is overcome by the present invention which increases the depth dimension of the loading door and, consequently, the depth in the recess only by giving up the front panel, in the case of a built-in dishwasher, without any modification to the body of the machine and with marginal modifications to the structural components of the loading door, fully compatible with the production technologies used today.

Figure 2 schematically represents a sectional view from front to back of a portion of a dishwasher embedded in accordance with the present invention and clearly highlights its simple structural differences with the embedded machines of the prior art.

A modular kitchen structure comprises a work surface 15 with a depth PL which is standardized with respect to a wall 16 with which it limits and which is between 600 and 630 mm. Below the work surface are housed (sometimes with interposition of a molding) modular cabinets and / or drawers with a standardized nominal PS depth of 570 mm, which include the thickness of the front panels to close the cabinets and / or drawers indicated with P1 and that is between 20-30 mm.

The dishwasher for hidden embedded installation therefore has a machine body 17 having a depth, indicated with P, of no more than 520 mm (in general 510 mm).

The loading opening of the machine is closed by means of a loading door, as shown in Figure 1, which increases the depth dimension of the machine by the amount H1 between 20 and 30 mm which can have a front panel of masking on it, with a thickness P1 so that the total dimension in depth is equal to that of the other units, with the masking panel level with the others.

In Figure 2, the dimension of the loading door of a conventional machine is represented by the broken line 18.

As already noted, this limits the depth of the recess of the counter door which cannot exceed the plane of the perimeter door flap by more than 15-20 mm.

In Figure 2, the base wall of the recess is in this case represented by the broken line 19.

On the other hand, just by omitting the masking of the machine, it is possible to extend the total dimension in depth of the machine at least up to PS = 570 mm and preferably more (perhaps with a suitable rounding of the edges of the external front panel 1 to join it to adjacent masking panels) even to match the depth dimension PL of the work surface, ie 600-630 mm.

This is obtained in a simple way, without modifications to the body of the machine and without substantial modifications to the production process, increasing the height H1 of the frame 2 of the external front panel 1 at least up to (570 - P) mm, that is, up to 50- 60 mm and even more.

This allows the drawing to form the recess 9 of the door panel 4 to be made deeper (also in this case without substantial modifications to the production process and in a manner that is compatible with the limits established by the drawing process) to a depth , measured with respect to the plane of the flap 3 of the tailgate, close to H1, preferably H1-10 mm, to leave an intermediate space for thermal and acoustic insulation and, in any case, less than H1-20 mm to explode as much as the largest volume available is possible.

The deep drawing to form the recess can be extended to the entire height of the counter door, without causing problems for the housing of the machine control devices and the detergent measurement / dispensing devices. Certainly, it is clear, as can be seen in Figure 2, that in the intermediate space between the front panel 1, the upper side of the perimeter frame 2 of the front panel and the upper side 5 of the counter door frame, there is a large volume, suitable for receiving control / programming devices and detergent measurement / dispensing devices such as those described in European patent application N 01830512.8 or even more conventional devices.

Particular embodiments of dispenser solutions designed specifically to exploit as much as possible the largest available volume will be returned later.

Now, it will be considered a more advantage offered by the greater depth of the washing chamber, obtained with a deeper drawing of the recess of the counter door.

In conventional dishwashers, the difference between the depth and width of the washing chamber limits the diameter of the rotating sprinklers, which can be housed in the washing chamber, to the smaller of the two dimensions, which is that of the depth.

Typically, if the width of the washing chamber can be between 560 and 580 mm (to leave an intermediate space with the external walls of the unit which has a standardized width of 600 mm), the maximum depth, on the other hand, is between 500 and 520 mm, so that the diameter of the sprinklers, in particular of the upper sprinkler, which is normally mounted under an upper basket, can at most be equal to such depth, to avoid interference with the walls.

This has the disadvantage of creating dead zones not only at the corners but also on the sides of the washing chamber, in which the spray action carried out by the sprayer is less effective.

To avoid this inconvenience, in EP-836,829, rotating sprinklers with articulated arms or telescopic arms of variable length have been proposed to increase the volume that can be sprayed directly.

Such a solution is complex and expensive.

On the other hand, it is clear that without constructive complications the increased depth of the recess of the counter door, and therefore of the washing chamber which is made substantially equal to the width, allows the use, at least for the upper basket, of a sprayer with a larger diameter, reducing dead zones to a minimum.

In addition, this advantage can be obtained without the need for modifications to the machine body, requiring modifications only to the upper basket to better exploit the largest available volume.

In this way, with the same machine body and with productive diversifications which only concern the loading door and a few accessories, such as the upper basket and the corresponding sprinkler, two different products can be obtained: a conventional concealed concealed dishwasher and a built-in dishwasher with an increased load volume and significantly improved washing performance.

These concepts become clearer from the comparison of the schematic front-to-back sections of Figures 3 and 4 which respectively represent the upper part of a conventional dishwasher and a dishwasher obtained from the previous one with the only one modification of the loading door and accessories.

In the machine of Figure 3, the depth of the machine is 540-550 mm to allow it to be flush level with the masking panel.

The size of the front door, with the lining of the counter door with the recess only at the bottom, leaves a useful depth of the washing tank at the top, limited to 450-460 mm and allows the accommodation of an upper basket 20 with a depth of the order of 440-450 mm.

The upper sprinkler 21 associated with the basket 20 cannot have a diameter greater than 440-450 mm, while the optimum diameter allowed by the width of the washing chamber would be 540-560 mm.

In the machine of figure 4, the depth of the machine is at least 570 mm and can even reach 600 mm.

The increased depth is obtained with only the modification of the loading door, whose counter door can be embedded deep forming the recess for its full height.

With this, the depth of the washing chamber, in its upper part, can be carried up to a minimum of 530-540 mm and it is possible that it can reach 560-570 mm, without the loading door protruding from the edge of the surface of work (at least 600 mm deep).

This allows the housing of a top basket 22 with a depth of 520-550 mm, and a top sprinkler 23, associated with the basket, with a diameter in the order of 520-550 mm, practically equal to the optimum diameter allowed by the width of the washing chamber.

It is, therefore, clear that with the simple modification of the basket 22, the sprayer 23 and the conduit 24 to feed water to the rotor (which should be longer with respect to that of Figure 3 to center the axis of the rotating sprinkler on the available space in depth) improved washing performance can be obtained.

This, in addition to the greater load capacity of the machine.

Now, using some examples, the advantageous possibilities offered by a loading door such as that described for housing control and detergent dispensing devices, both conventional and innovative, can be addressed.

Figure 5 schematically represents a sectional view from front to back of the top of the loading door.

In the intermediate space between the front panel 1, the upper side of the perimeter frame 2 and the upper side 5 of the counter door frame, a conventional electromechanical programmer 25, with a horizontal axis, as shown, or a vertical one, can be housed conveniently

The control knob 26 may be arranged in the front, as illustrated, or even on the upper side of the frame,

or even, embedded, with only a perimeter portion accessible through a window made in the front, on the upper side of the frame or even on one side of the frame, as for example, is proposed in EP 728473.

A detergent measuring / dispensing device 27, of the conventional type, with a closure shutter 28, can be housed in the intermediate space between the front panel 1 and the base 9 of the counter door recess, which is shaped locally to form an intermediate space of adequate width, with a minimal reduction in the volume of payload.

The detergent measuring / dispensing device, instead of having a pivoting shutter 28, as illustrated, can be of the type that has a sliding shutter (as taught by EP780087) or a rotating diaphragm shutter, as It is taught by document EP10049.

The upper side of the frame 2 can be equipped, in the installation, with a molding 29, made of wood or plastic, coordinated with the modular kitchen structure in which the machine is installed.

Alternatively, in the variant shown in the sectional view of Figure 6, the upper side of the frame 2 may be inclined, with the corresponding inclined arrangement of the programmer 25 and the corresponding knob (which can be replaced by an electric programmer and the corresponding keyboard).

In this case, as shown in the sectional view of Figure 7 (according to the Z / I view of Figure 6), the vertical sides of the frame 2 may also be inclined or pointed.

This may, advantageously, be to join the surface of the front panel 1 to the modular kitchen structure in a less abrupt manner, if this surface protrudes from the plane 30 of the masking panels.

The corners between the different sides of the frame 2 may, in a known manner, be welded and wedged.

Alternatively, the front panel 1 and the corresponding frame 2 can be obtained by molding plastic material.

This allows to obtain profiles in convex half-round to meet the aesthetic requirements with greater flexibility.

E02425427

For example, Figure 8 represents a perspective view of a dishwasher according to the invention in which the loading door 31, which protrudes with respect to the plane of the panels 32, joins them with a profile having a section approximately elliptical horizontal which masks to a greater degree the greater dimension of the machine and makes the set particularly harmonious and pleasing to the eye.

The intermediate space between the front panel 1, the upper side of the perimeter frame 2 and the inner upper side of the counter door frame, not only allows for easy accommodation of control and / or measurement / dispensing detergent devices as proposed for example in European patent application N 01830512.8, it also offers the possibility of developing devices that fully exploit the available space.

While in known detergent metering / dispensing devices, which use a pivoting shutter (as shown in Figure 1), the rotation of the shutter requires that a substantial free volume be provided in the washing chamber , to allow the shutter to be opened without interference, in a loading door such as that which is the subject of the present invention, the substantial free volume can easily be obtained inside the upper side of the counter door frame.

This solution is schematically represented in the sectional view of Figure 9.

In Fig. 9, a detergent container 33, generically parallelepipedically, is housed in the volume between the front panel 1 and the upper side 5 of the counter door frame.

The container 33 extends downwards in a hopper 34, also housed inside the counter door frame.

The container 33 is closed below by a pivoting shutter 35 on a pin 36, arranged near the front panel 1.

The shutter 35 is pushed into the open position by a spring not shown and, when open, rests on one side 37 of the hopper 34, allowing the free discharge of the detergent into the wash tank.

The closed position of the shutter 35 is secured by devices known per se and not illustrated, such as a retaining ratchet, released by an electromagnetic control.

In its path from the closed position to the open position (and vice versa) the shutter remains fully or substantially housed in the hopper 34 and does not interfere with the dishes housed in the washing chamber and, in particular, in the recess of the counter door .

The container 33 is closed at the top by means of a lid 38, pivoting on a pin 39, which can be opened and can take the position 40 represented with a broken line.

Opening is allowed only if the loading door of the machine is slightly open.

Otherwise, the side 41 of the lid interferes with the body of the machine which hinders its rotation on the pin 39.

Thus, it is clear that the cover 38 can be pushed into the open position by a spring and can automatically open and close with the respective openings and closures of the loading door.

To reduce friction and prevent wear, the cover 38 may be equipped with a roller bearing 52.

To minimize the requirements for the user and give maximum ergonomics, the closure of the discharge shutter can also be made automatic and can be subordinated to the opening of the loading door.

Figure 10 schematically represents a kinematic mechanism suitable for this purpose.

A push rod 42 is housed on the upper side of the frame 2 of the loading door which, through the effect of a spring 43, exits the frame, through an opening of the wing 3 of the counter door and interferes with the machine body

With the loading door slightly open, the rod takes maximum extension outside the frame as shown in the figures.

With the loading door closed, the rod is pushed completely into the frame 2.

An articulated arm 44 is pivotally attached at its end (preferably bracketed, to prevent the development of rotation torque) on a pin 45, which is an integral part of the rod 42.

At the other end of the arm 44, a groove 46 is formed in which a pin 47 is inserted that forms an integral part of the discharge plug.

E02425427

09-23-2014

When the loading door is opened, the arm 44 is pushed to the position shown and the coupling between the arm 44 and the shutter 35 forces the shutter 35 to take the closed position.

The shutter remains locked in such position by the effect of an elastic jump device not shown, such as a common ratchet, even if the loading door is closed afterwards.

5 Certainly, when the loading door is closed and the arm takes position 49, represented by a broken line, the pin 47 can slide freely in the groove 46.

During the course of the wash cycle, the release of the ratchet, electromechanically commanded, allows the shutter 35 to rotate freely and take the open position.

In this step, the spike 47 slides freely in the groove 46 and the arm 44 rotates over the spike 45 to take the

10 position 50, represented by a broken line, so that the opening of the shutter 35 takes place without hindrance.

Opening the loading door at the end of the wash returns the system to the state represented by a continuous line.

Figure 11 schematically represents an equivalent articulated system in which the rod 42 becomes superfluous and its function is carried out by the lid 38 of the detergent container.

In this case, the arm 44 is pivoting on a pin 51 arranged in a suitable position on one side of the cover 38.

The lid 38 can be manually operated to open or, preferably, can be brought back to its open position by means of a spring 52 so that it opens automatically with the opening of the loading door.

20 Since the kinematic mechanism is identical to that already described, any other explanation is superfluous.

It is clear that instead of the kinematic mechanism described, other devices can be used, for example using a pinion-rack, with releasable gear, as well as couplings with a flexible cable between rod / cover and discharge plug.
