Description

MACHINE FOR CLEANING AND AUTOMATIC DRYING OF DENTAL PROSTHESIS

OBJECT OF THE INVENTION

The invention, as expressed in the statement of the present specification, refers to a machine for the automatic cleaning and drying of dental prostheses, providing several advantages and innovative features, apart from others inherent to its organization and constitution, which will be described in detail later and that represent a remarkable improvement of the current state of the art in its field of application.

More particularly, the object of the invention is focused on a machine that has the purpose of serving to perform the cleaning and drying of the dental prostheses by the dental technician, serving both to eliminate substances adhered thereto in its manufacturing process as for the elimination of chemical substances in the cleaning and sanitation protocols that these dental prostheses must comply with. The machine has the peculiarity that it works based on water vapor, pressurized water and air, allowing the cleaning and drying of a large number of dentures in an automated way.

FIELD OF APPLICATION OF THE INVENTION

The present invention is part of the technical sector of the industry dedicated to the manufacture of cleaning devices and devices, focusing particularly on the field of dental prostheses, but without discarding and similar elements.

BACKGROUND OF THE INVENTION

At present, there is the problem that dentures can only be cleaned manually and unitarily to remove particles that adhere to them in the manufacturing process, with the consequent loss of time involved.

The objective of the present invention is, therefore, to develop a machine that avoids said inconvenience by allowing cleaning and sanitization of said prostheses automatically and, in addition, to multiple units at the same time, it should be noted that the applicant's part is unknown. existence of any other invention or similar application machine that has technical, structural and constitutive characteristics similar to those presented here.

EXPLANATION OF THE INVENTION

Thus, the machine for the automatic cleaning and drying of dental prostheses that the present invention proposes is configured as a remarkable novelty within its field of application, since, according to its implementation and in a restrictive way, the objectives previously achieved are satisfactorily achieved. indicated as suitable, the characterizing details that make it possible conveniently included in the final claims accompanying the present specification thereof. Specifically, what the invention advocates is a machine in which, by means of an electronic programmable control unit, different washing processes are carried out, based on water vapor and pressurized water, and drying processes based on air. For this, the machine is configured from a metal frame that determines a watertight interior compartment suitable to accommodate a container in which several dental prostheses can be incorporated, said control unit being coupled to said metal frame.

This frame has an outlet of residual liquids in its lower part and an outlet of gases in its upper part, and is equipped with a vertical opening front door and a tight seal.

The aforementioned door is provided with safety sensors and solenoid valves that prevent its opening during any of the washing and drying processes that are carried out inside the frame.

On the other hand, said processes are controlled by the aforementioned electronic unit, which marks the times of said processes and controls the opening and closing solenoid valves of the door as well as the opening and closing solenoid valves of steam, water and air that They give way to these elements inside the machine.

Water, steam and air supplies are made through connections provided for this purpose on the back of the machine, there is an individual collector for each element that, in turn, is connected to a plurality of pipes that line the walls of the interior compartment distributed homogeneously, and which are distributed alternately on all its walls except for the base, that is, both on the top and on the side and bottom walls of said compartment.

It should also be noted that the interior of said compartment is provided with metal guides designed to facilitate the introduction of the container where the dentures to be cleaned are placed, which preferably adopts the configuration of a container basket.

In this way, the prosthesis is cleaned as follows:

First, the prostheses are deposited in the container basket, then the machine door is opened manually and the basket is inserted into the inner compartment, conveniently supporting it on the guides provided for that purpose. The door is closed and the times to be executed in each process are programmed in the electronic unit, which start automatically causing successive jets of steam, water and air.

Once the washing and drying processes are finished, the door is opened manually and the container basket is removed, the work of the machine being terminated, whose advantage lies mainly in the ability to clean and dry multiple prostheses at once, thus how to do it automatically, quickly, hygienically and efficiently. It is therefore verified that the machine for the automatic cleaning and drying of dental prostheses proposed represents an innovative structure of structural and constitutive characteristics unknown until now for this purpose, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that is requested.
