Description

BACKGROUND OF THE INVENTION

Object of the Invention

The present invention relates to a machine for washing supermarket accessories, although the machine is specially designed for the washing and disinfection of shopping baskets, both hand baskets and wheeled baskets. The configuration of the machine enables the size thereof to be considerably reduced making it more ergonomic and also enables there to be an easier and more comfortable access to the different mechanisms of said machine in case of eventual revisions and repairs. The machine also enables the use of various tools designed specifically for washing and disinfecting other items, such as trays, knives, butcher's and fishmonger's gloves, etc.; and in general, utensils and accessories used in supermarkets, butchers' shops, fishmongers and similar.

Technical Problem to be Resolved

At present, dishwashers are known that are configured to carry out the washing of cutlery and other elements, such as different containers, all elements that are kept inside the dishwasher in a static position during washing, such that in some cases the washing of said containers is somewhat deficient, mainly due to the fact that the various surfaces of said containers are washed by the spraying of the liquid fluid coming out of injection nozzles from fixed directions, with the possibility that certain areas of the surfaces of said containers do not receive the spraying of the liquid fluid, or even receiving it is not sufficiently effective to carry out the cleaning of the containers.

Furthermore, at present the washing of baskets and trays is generally done manually, so this way of washing is expensive and in some cases it is not efficient enough.

Also known are the rotary basket washing machines that comprise an inside space where a frame with means of securing the basket is located; where said frame together with the basket rotate during the washing phase by means of a motor element that transmits the movement thereof to a shaft connected to the frame by means of a transmission mechanism. The location of the motor element and the transmission mechanism are located in an area of the machine that is difficult to access, making it difficult to assemble and maintain the machine.

Another drawback of these machines is that the means for securing baskets comprise complex anchoring devices that excessively lengthen the time taken to secure the basket; they are also inflexible and ineffective anchoring devices in the sense that it is quite difficult to secure some basket models.

SUMMARY OF THE INVENTION

In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a machine for washing accessories that comprises an inside space that houses a frame configured to support at least one accessory to be washed; wherein the frame is connected to a front shaft that is configured to rotate during the washing of the accessory.

The front shaft is further configured to drag the frame during the rotation thereof which includes anchoring devices configured to secure the accessory to the frame.

The frame comprises a cross-member connected to the front shaft and a base formed by two angular supports that include first branches that couple to the cross-member, and second branches on which the accessory to be washed rests.

The two angular supports of the base have a first adjustment to be able to vary their height positioning in a substantially vertical plane, and the angular supports of the base have a second adjustment to be able to vary the distance between the two angular supports of the base in a substantially horizontal plane.

The first branches of the base of the frame include a set of first through holes, and the cross-member of said frame includes second through holes; wherein the first branches of the base are coupled to the cross-member by means of anchoring elements that fit into some of said first through holes of the first branches and into some of the second through holes when they are facing each other.

The second branches at the base of the frame are fastened to a lower portion of the first branches of said base; wherein the first branches include lower supports where ends of the second branches are fastened to the first branches by means of fastening elements.

The second branches of the angular supports that make up the base include guides that are configured to be able to couple therein opposite edges of a tool that supports at least one accessory to be washed.

The guides of the second branches comprise some longitudinal conduits arranged along said second branches of the base of the frame.

Each of the second branches of the base comprises a structure formed by a main part with an angular profile and a removable secondary part also with an angular profile, which has pins configured to fit into holes located in the main part; wherein the structure of the second branches is configured to vary the width of the guides formed by the longitudinal conduits to adapt them to the width of the opposite edges of the tool when coupled to the guides of the base of the frame.

In one embodiment of the invention, it comprises a first tool with a tray configuration including parallel conduits; in a second embodiment it comprises a second tool including a set of raised supports configured to support gloves; and in a third embodiment of the invention it comprises a grate structure configured to support knives and other cutlery.

In a main embodiment of the invention, the frame is intended to secure a shopping basket resting on the second branches of the angular supports making up the base of the frame; wherein the basket is immobilised by means of the securing devices located at end portions of the second branches of the two angular supports forming the base of the frame.

At the highest point thereof, the machine comprises a mortise located above the inside space where the frame is housed; wherein inside said mortise there is at least one motor element configured to transmit rotary movement to the front shaft to which the frame assembly is connected by means of the cross-member thereof.

The mortise is accessible through an upper removable cover located in a horizontal plane opposite a bottom side of said mortise, while control buttons are located on a front plate which partly defines the lateral contour of said mortise.

The rotary frame is completely designed to achieve greater simplicity and safety in the anchoring of the accessory to be washed and, above all, to enable dimensional adjustment to any size and shape of the accessory to be washed.

Therefore, the cross-member on which the two angular supports are arranged is now used in a totally adjustable way (vertically and horizontally), which angular supports are in the shape of a bracket, located in parallel, each of which includes own means thereof for blocking and fastening the accessory to be washed.

The motor element to provide the rotation of the frame is located in the upper mortise above the inside space; wherein the control and adjustment electronics are also located in said upper mortise.

This allows us to considerably reduce the size of the machine and to have an easier and more comfortable access to the transmission system in case of eventual revisions and/or repairs.

It should be noted that the machine of the invention has removed any tank or reservoir of liquid fluid in the lower portion, which is replaced by the cleaning tank itself, for which a heating resistor is located in said cleaning tank; thus achieving a considerable reduction in the size of the machine, making it more ergonomic.

The very structure and multiple adjustments of the new bracket-shaped supports, which are also equipped for quick anchoring, allow us to use the various tools designed specifically for washing and disinfecting knives, butcher's or fisherman's gloves, etc.

Next, to help better understand this specification and as an integral part thereof, a series of figures is attached in which the object of the invention is depicted in an illustrative and non-limiting manner.
