1. A door lock device for a household appliance door, said household appliance door being provided with a prong, said device comprising: a mechanical module, for retaining said prong in a closed position, or releasing said prong for an opening of said household appliance door,opening means, comprising:an unlock slider, movable between a first position and a second position, and capable to interact with said mechanical module,returning means of said unlock slider in said first position, andan activation member, having an activation element and guiding means for a mutual movement between said unlock slider and said activation member,wherein, when said prong is retained by the mechanical module, upon pressing said activation element, said guiding means cause an interaction of said unlock slider with said mechanical module to release said prong, and wherein when said prong is brought close to said mechanical module to be retained for closing the household appliance door, by keeping pressed said activation element, said guiding means allow said mechanical module to retain said prong by a combined action of contrast means and said returning means of said unlock slider, andwherein said guiding means comprises: one or more cams, each of which has an upper profile and a lower profile arranged on said unlock slider, andone or more side reliefs, arranged on said activation member, in order to interact with said one or more cams,wherein, with said prong retained by said mechanical module, upon pressing said activation element, said one or more side reliefs of said activation member interact with said upper profile of said one or more cams, causing the interaction of said unlock slider with said mechanical module to release said prong, and wherein, when said prong is brought close to said mechanical module to be retained for closing the door, by keeping pressed said activation element, each of said one or more side reliefs follows a profile of a respective cam, to which it remains constrained by a combined action of said contrast means and said returning means of said unlock slider, sliding on said lower profile of the respective cam, so that an action of said returning means on said unlock slider allows said mechanical module to retain said prong. 2. The device according to claim 1, wherein said mechanical module further comprises: a hook suitable to engage and retain said prong when said household appliance door is closed, anda strut, interacting with said hook, in order to keep said hook engaged with said prong, when said household appliance door is closed,wherein said unlock slider further comprises a projection, suitable to interact with said strut to disengage said strut from said hook, so that said hook disengages from said prong, allowing opening of the household appliance door. 3. The device according to claim 2, wherein said unlock slider is arranged under said strut. 4. The device according to claim 1, wherein said activation member has a slot, andsaid contrast means comprises a first spring, inserted within said slot and connected with said activation element, so that said first spring is compressible by said activation element, and after pressing, said activation element returns to its original position. 5. The device according to claim 1, wherein said returning means comprises a returning spring. 6. The device according to claim 1, wherein said activation element is operated by a handle of said household appliance door or by a further member. 7. The device according to claim 2, further comprising an electric module provided with an activation and block pin, capable of assuming an operating position, in which the activation and block pin is extracted to inhibit operation of the device, preventing the opening of said household appliance door, and a resting position, in which the activation and block pin is retracted, wherein said mechanical module further comprises a block slider, capable of interacting with said activation and block pin, such that when said activation and block pin is in said operating position, said block slider remains blocked, andwherein said strut is operatively connected with said block slider. 8. The device according to claim 7, further comprising an emergency lever, manually operable and capable to activate a mechanism, in order to force passage of said activation and block pin from said operating position to said rest position. 9. The device according to claim 1, wherein the activation element is a button.
