Abstract
Description
- The invention relates to a door locking device for washing machines, in particular dish-washing machines for industrial use, adapted to permit the door to be effectively locked during the carrying out of the washing programs which have been respectively selected in these machines.
- The present washing machines like the dish-washing machines for industrial use are substantially provided with a washing tank for housing the dishes to be cleaned, in which the rotating spraying arms for the solution for cleaning dishes are arranged, which- are connected to a pump included in the circuit for circulating such cleaning solution, and this tank in turn is accessible through a front opening which can be closed by a door, hinged to the housing of these machines and associated to a locking bolt of mechanical type, adapted to engage corresponding seats provided in the peripheral edge delimiting such an access opening, which door may be moved from an opened to a closed position thereof, in which it is respectively permitted the access to the tank for introducing the dishes to be cleaned therein and extracting the cleaned dishes therefrom, at the condition in which the spraying arms are stopped and the cleaning solution is not sprayed onto the dishes, and in which such access is prevented for carrying out the relative dish washing programs.
- This door is also associated to at least a control switch of per se known type, which is connected operatively in the electric circuit of the associated machine together with the different component parts thereof, and which can be operated by the same door from an off to an on position thereof, and vice versa, in order to provide respectively for switching off such electric circuit thereby preventing each selected washing program from being carried out when the door is moved to the opened position thereof, and switching on such electric circuit thereby permitting the washing program to be carried out when such door is moved to the closed position thereof. Generally, such control switch is mounted on a side position with respect to the door, or also at the level of the machine access opening, and is operated by the door itself by means of adequate control devices provided additionally in the machine and associated to both it and the door. However, the so realized washing machines even if operating in a satisfactory way, require the presence of at least two separated component parts such as the locking bolt and the control switch which are mounted in the machine with various operations on positions moved away from each other, which therefore make too complicated and not much practical in the use these machines.
- The present invention has the object to provide for a door locking device of the kind referred to which is of simple type, shaped in the form of a single component part incorporating both the locking bolt and the control switch, which can be assembled easily and quickly in correspondence of the machine door, by providing also a safe and reliable machine operation and stop, by moving the door on the respective closed and opened positions thereof.
- This door locking device is realized with the constructive characteristics substantially described, with particular reference to the enclosed patent claims.
- The invention will be better understood from the following description, given solely by way of not-limiting example and with reference to the accompanying drawings, wherein :
- Figs. 1 and 2 show schematically a respective cutaway side and plan view of a door locking device in accordance to the invention, moved on a first operative position thereof ;
- Fig. 3 shows a front view of both the locking device and the door, shown in the Fig. 1 ;
- Fig. 4 shows a plan view of the item of Fig. 3, cutaway along the line A-A ;
- Fig. 5 shows a side view of the present locking device, moved on a second operative position thereof.
- In the Figures referred to, the present door locking device for washing machines, in particular dish-washing machines for commercial use is shown, which is mounted in correspondence of the front door 6 for the access to the
washing tank 7 of these machines, in which the dishes are introduced and extracted respectively prior and after the carrying out of the relative washing programs. - This locking device is substantially constituted by a casing shaped as a
plate 8, having almost rectangular form and reduced thickness, made of plastic material of conventional type, which is fitted externally onto the horizontal upper wall 9 of thewashing tank 7 and in a correspondinginner cavity 10 of the washingmachine closing panel 11, which is applied above such upper wall 9, wherein the cavity is provided in correspondence of thevertical front wall 12 of such tank, which in turn is provided with the throughopening 13 for the access to the tank inside, wherein the door 6 bears against the outer surface of such wall when moved on the closed position thereof, thereby providing also to close the through opening 13. - The junction of the plate shaped
casing 8 with the tank upper wall 9 is performed by means ofscrews 14 or the like, which are inserted throughcorresponding side holes 15 of the plate shapedcasing 8 and screwed onto such an upper wall. The plate shapedcasing 8 extends in a longitudinal direction up to a position above the door 6, when this latter is moved on the closed position thereof, and is also provided with astud 16 arranged transversally thereto and housed intocorresponding seats transversal stud 16 there are articulated both the corresponding end portions of ashaped nib 19 having flattened form, and which is laid onto the upper surface of the plate shapedcasing 8, and afeeler pin element 20 arranged at a superimposed relationship to such nib, and the other end portions of both such nib and feeler pin element are so shaped as to form respectively acollar 21 bent almost orthogonally and directed downward therefrom, defining a throughhole 22, and situated in correspondence of the position of the door 6 below it, as well as penetrating through a corresponding through opening 23 of the plate shapedcasing 8, in such a way as to project slightly beyond the lower edge of this latter, and to form abent portion 24 directed downward and so dimensioned as to penetrate through thethrough hole 22 of said collar, by projecting itself slightly beyond the lower edge thereof. - The
nib 19 is further associated to at least acompression spring 25 or similar resilient means, housed on the terminal zone of the plate shapedcasing 8 provided in correspondence of the door 6, and the end portions of which are laid on and fixed against the corresponding zones of upper surface of thenib 19 and inner surface of the washingmachine closing panel 11, thereby stressing in compression such nib against the plate shapedcasing 8, and thus keeping thecollar 21 thereof always introduced through the corresponding through opening 23 of the same casing. - In turn, the
feeler pin element 20 is associated to at least atorsion spring 26 or similar resilient means wound on thetransversal stud 16, which urges it in such a way as to keep it steadily pressed against thenib 19 and with thebent portion 24 thereof penetrating through thethrough hole 22 of thecollar 21 of the plate shapedcasing 8. - Moreover, the
end portion 27 of such feeler pin element which is articulated on thestud 16 is able to act against a movablecontrol push button 28 of anelectric microswitch 29 or other suitable switch means of per se known type, mounted in theinner cavity 10 of the washingmachine closing panel 11, on a position above the plate shapedcasing 8, and connected operatively in the electric circuit of this machine, together with the remaining circuit component parts thereof (not shown), in such a way that such articulatedend portion 27 can operate themicroswitch 29 from the one to the other one of its switched off and on positions of such electric circuit, thereby causing the machine to be stopped and operated, in the conditions in which thefeeler pin element 20 is respectively kept on its operative position compressed against thenib 19 or moved on the other operative position thereof, raised with respect to the same nib, by rotating slightly around thestud 16. - In turn, the machine door 6 is provided with a
recess 30 on its upper surface, situated in correspondence of the zone of theclosing panel 11 in which thecollar 21 and thefeeler pin element 20 projected downwards are situated, which recess is adequately shaped in order to be able to house both such collar and feeler pin element when the door 6 is moved in the closed position thereof, in correspondence of said collar and feeler pin element. - In the present case, the
recess 30 has a profile constituted by twowalls recessed zone 33 at the centre of the door 6, in which a vertical projectedpart 34 is provided, which is directed upward for the entire height of the recess and provided in correspondence of thefeeler pin element 20, said walls of therecess 30 being adapted to house the correspondinginclined walls collar 21. - In this manner, it appears evident the operation of the present door locking device.
- In fact, when the machine door 6 is moved on the opened position thereof, evident from the Fig. 5, the
recess 30 of this latter doesn't coincide with both thecollar 21 of thenib 19 and thefeeler pin element 20, which are protruded downward from the plate shapedcasing 8, since such nib and feeler pin element are urged into such operative position by therespective springs end portion 27 of thefeeler pin element 20 isn't moved and therefore does not act against thecontrol push button 28 of themachine microswitch 29, so that this latter remains operated on the switched off position thereof in which the machine is off, in which condition the dishes can be introduced and extracted in the tank thereof, respectively prior and after the carrying out of each selected washing program. - On the contrary, when the machine door 6 is moved on the closed position thereof, evident from the Fig. 1, the sliding of the same against the
inclined wall 36 of thecollar 21 causes thenib 19 to be slightly lifted and displaced on the other operative position thereof, against the action of thecompression spring 25, and a consequent progressive penetration of said nib in therecess 30 of the door 6, up to its complete penetration therein. - Besides, on this door closed position the lower end portion of the
bent portion 24 of thefeeler pin element 20 arranges itself against the vertical projectedpart 34 of the door recess 30, which causes it to be lifted thanks to the rotation of said feeler pin element around the associatedstud 16, against the action of the associatedtorsion spring 26, in which condition the articulatedend portion 27 of said feeler pin element acts against thecontrol push button 28 of themachine microswitch 29, so that this latter is actuated on the switched on position thereof, in which the machine is on, and is kept on this state in the course of carrying out of each washing program, thanks to the projectedcollar 21 engaging therecess 20 which fact prevents any accidental opening of the door, up to the end of such program or any possible premature and voluntary breaking off of the same program, due to whatever reason for example for introducing additional dishes to be cleaned in the machine. - In this way, there are evident the advantages obtained by means of the present door locking device for washing machines, which is realized in the form of a single component part incorporating both the
nib 19 and thefeeler pin element 20, performing the function of door locking bolt, as well as incorporating also theswitch 29 to control the machine operation. In fact, this component part is of a simple and useful type and may be also fitted easily and quickly on a determinate position of the machine, with few operations, and is able to ensure the machine stop and operation in a safe and reliable manner, by acting on the door thereof, and moving such door on the respective closed and opened positions thereof, in which circumstance both the door locking bolt and the machine control microswitch are actuated as described above.
