Definitions
- the present invention relates to a dispenser of washing agents for a household washing machine, in particular a dish-washer.
- Dispensers of washing agents of the type referred to usually comprise a body made of plastic material which is designed to be fixed to and/or set partially into the side of the door of the dish-washer so that the front part or area of the body itself is set facing the inside of the washing chamber of the machine.
- a compartment or cup for containing a given amount of detergent, usually in the form of powder or in the form of tablets, which is necessary for execution of a washing cycle .
- the space is equipped .with a respective lid, which ' is usually hinged by means of pins to the body of the dispenser.
- the door of the dishwasher is angularly mobile about a horizontal axis, i.e., it can be tipped or turned over between a closed position, in which the door is in a vertical position, and a position for loading the machine with dishes, in which the door is in a horizontal position.
- the majority of dispensers are generally configured so that the opening of the cup faces upwards when the door of the machine is in a substantially horizontal position. It is only with the cup in this condition that the user is able to introduce a dose of washing agent into the cup, close the corresponding lid of the dispenser, and then close the door of the machine. Opening of .
- the lid at the appropriate moment of the washing cycle is controlled by a programmer, or timer, of the dish- washer so as to bring about dropping of the detergent into the washing chamber both by gravity and as a result of the splashing of liquid coming from the members that spray water inside the dish-washer.
- the door for loading the machine is not angularly mobile but rather slides linearly on guides (see, for instance, FR-A-2674426) .
- the dispenser of washing agents is fixed to the door of the machine or at any rate to a wall or vertical surface delimiting the washing chamber.
- the dispenser must therefore be designed to operate always on one and the same plane of lie, which is independent of the condition of opening or closing of the door. This entails a fabrication of the dispenser that is somewhat different as compared to what has been described previously with reference to dish-washers that are equipped with doors that turn over.
- the programmer or timer of the machine will control opening of the main lid, with the consequent delivery of the detergent in a way similar to what was described previously.
- the solution referred to in the prior document mentioned above enables facilitation of charging of the detergent in the case of machines with doors that turn over, since this form of charging can be carried out with the door itself almost in a vertical position.
- the same technical' solution could moreover be adopted in the case of machines equipped with doors that slide linearly.
- the purpose of the present invention is to provide a new dispenser of washing agents for a washing machine which is simple to produce, convenient to use, ensures reliable operation, and has a contained cost, and where, in particular, proper charging and/or dosing of the detergent may be performed in a convenient and easy manner for the user, both in the case where the dispenser is fixed on sliding doors or on constantly vertical surfaces and in the case where the dispenser is fixed on doors that turn over.
- a device for dispensing washing agents for a household washing machine in particular a dish-washer, having the characteristics specified in the attached claims, which are to be understood as forming an integral part of the present description.

- the reference number 1 designates, as a whole, a dispenser of washing agents built according to the present invention, designed for use on a washing machine (not represented) , which here is assumed as being a dish-washer.
- the dispenser 1 has a main body 2, preferably designed for being housed at least in part in an opening provided on the inner side of the door of the dish-washer, it being possible for the said door to be indifferently of the type that turns over or of the sliding type.
- the aforesaid opening for at least partial setting-in of the body 2 may likewise be defined in a vertical wall of the washing chamber of the dish-washer. Consequently, in general terms, the body 2 can be fixed to any surface delimiting the washing chamber of the dish-washer, in particular a surface of one of its vertical walls, in the position of lie visible in Figure 3 and Figures 7 to 9.
- the body 2 may be obtained by welding of a front piece and ' a rear piece made of thermoplastic material .
- top, bottom, front, “rear”, etc. are to be understood as referring to the position that the dispenser 1 occupies when it is mounted on a vertical surface, i.e., in the typical operating condition viewed from- inside the washing chamber of a dish-washer with the door closed.
- a tank for containing a liquid washing agent or brightening agent.
- the letter T designates the cap of an opening, in • communication with the aforesaid tank, the said opening being used for charging the container with the brightening agent.
- Designated by AS is an opening for discharging, through which a dose of said brightening agent can be made to flow towards the washing chamber of the dish-washer.
- Designated by SP is a warning light indicating the level of the brightening agent present inside the corresponding tank.
- a housing designated by 3 in the Figures, which defines a seat or central depression designed to accommodate at least one portion of an intermediate articulation element, designated as a whole by 4.
- the intermediate element 4 fulfils functions of containment of the detergent, as will emerge clearly from what follows.
- the intermediate element 4 is hinged, substantially at its bottom end, to the body 2 by means of two lateral pins, one of which is designated by 5 in Figure 4, the said pins being of known construction.
- the pins 5 may be integral with the body 2 and partially inserted into respective holes present in the intermediate element 4 or, instead, be replaced by hinging elements that are technically equivalent.
- a compartment or tray 6 which is open towards the front part of the dispenser 1 (see again Figure 4) , the said compartment 6 being designed to receive a given dose of detergent necessary for carrying out a washing cycle.
- the said detergent is in powder form, but it should be borne in mind that the invention may be applied also in the case of detergents in the form of tablets, gel, foam, liquid, etc.
- the compartment 6 is open also at the top part of the element 4, i.e., in the longitudinal end opposite to the one in which the pins 5 are provided.
- the number 7 designates, as a whole, a lid or lid that can be turned over, provided for closing at least partially both the housing 3 and the compartment 6.
- the lid 7 is hinged, or in any case constrained, to the intermediate element of articulation 4, and the latter, as has been said, is, in turn, hinged, or in any case constrained in its movement, to the body 2.
- the lid 7 is substantially constrained at the top longitudinal end of the articulation element 4, i.e., the end opposite to the one in which the pins 5 are provided.
- a tubular seat 8 In the proximity of its top end, in each side of the element 4, there is defined a tubular seat 8, only one of which is visible by way of example in Figures 2 to 5, the said tubular seat 8 extending in a respective through hole present' on the homologous side of the lid 7.
- the lid 7 is able to perform angular movements with respect to the element 4.
- the seats 8 could form part of the lid 7 and be inserted in holes present in the element 4.
- a spring 9 which reacts between the element 4 and the lid 7, in the sense that it exerts a load on the latter so that it will assume a respective first opening position for delivery of the detergent, as illustrated, for example, in Figure 4.
- an actuating element or push-button 16 set in a position corresponding to a respective passage defined in the lid 7, in such a way as to be directly accessible to a user both from the top part and from the front part of the lid 7.
- the shaft 10, the arms 11, 12, the seat 13 and the spring 14, together with the push-button 16, make up a system for manual clamping/release of the assembly consisting of the lid 7 and the articulation element 4 with respect to the body 2 of the dispenser.
- Designated by 18 in Figure 4 and Figures 7 to 9 is a gasket, inserted in a respective housing defined on the inner surface of the lid 7.
- the gasket 18 is designed to operate so as to form a seal on one lip 4A of the element 4, which delimits the compartment 6 along three sides, remaining, instead, at a distance from the end of a chute portion 3A (see also Figures 2 and 3) of the top part of the housing 3, said portion 3A having the function of facilitating charging of the detergent into the compartment 6.
- the presence of the gasket 18 enables, in the condition of the lid 7 being closed, isolation of the inside of the compartment 6 just along three sides with respect to the outside.
- Such an arrangement may be provided to enable a certain amount of water to enter the compartment 6 during the initial steps of a washing cycle carried out in the dishwasher, and again in conditions of closing of the lid 7, in order to bring about a partial dissolution of the detergent contained therein prior to its supply to the washing chamber.
- the end of the chute portion 3A could be longer or, in any case, envisaged in such a way as to come into contact with the gasket 18 so that, in the condition of the lid 7 being closed, the inside of the compartment 6 will be completely isolated from the outside.
- the reference number 19 designates a tooth, defined at the end of a projection, which branches off from the inner surface of the lid 7 in the bottom area of the latter.
- the tooth 19 is designed to co-operate with an engagement lever designated, as a whole, by 20, which is associated to the body 2 so that it will be able to perform an angular movement, the said lever 20 being designed in a manner known in the field.
- the lever 20 has an engagement portion 21, which defines an inclined plane, on which the tooth 19 is able to slide during closing of the lid 7 with respect to the lever.
- the surface of the tooth 19 is shaped so as to enable or facilitate the movement of opening of the intermediate element 4, enabling its rotation with respect to said engagement portion 21, as will emerge more clearly from what follows.
- the surface of the tooth 19 is rounded instead of forming an inclined plane with sharp edge, as is typically the case of dispensers of a known type.
- the dispenser 1 is equipped, in its rear part, with actuator means of a type in themselves known and hence not shown in detail in the attached drawings.
- the said actuator means are provided for producing, by means of a known mechanism, actuation of the lever 20 in order to obtain opening of the lid 7.
- the aforesaid actuating means are activated by the programmer or timer of the dish-washer in the course of the washing cycle at the moment in which supply of the detergent contained in the compartment 6 is to be provided, as will emerge clearly from the ensuing description.
- the arrangement is such that activation of the aforesaid actuator means brings about movement of a transmission element, which can be seen in part in Figure 4 and Figures 7 to 9 and is designated by 23, in order to bring about angular movement of a respective shaft inserted in a passage that traverses the body 2.
- a transmission element which can be seen in part in Figure 4 and Figures 7 to 9 and is designated by 23, in order to bring about angular movement of a respective shaft inserted in a passage that traverses the body 2.
- At one end of said shaft designated by 24 in Figure 4 and Figures 7 to 9
- there is fixed the lever 20 in such a way that, with the angular movement of the shaft, there is a corresponding identical angular movement of the lever 20.
- the position of lie of the body 2 is always the one that can be seen, for example, in Figure 3 and Figures 7 to 9.
- the dispenser is typically in the condition of the lid 7 being open, as illustrated in Figure 9 or, more precisely, in Figure 4 (in Figure 9, the lid 7 is at the start of its opening movement; the complete angular movement of the lid, during delivery of the detergent is approximately through 120° - see Figure 4) .
- condition of opening of Figure 9 could correspond to a condition of maximum opening of the lid 7 during delivery of the detergent, for instance, in the case where the aim is to limit the overall operating dimensions of the dispenser, in order to recover space for a rack for containing the dishes inside the washing chamber of the machine.
- the user After loading the dishes into the dish-washer, the user brings about complete manual closing of the lid 7 by pressing the lid towards the body 2. In this way the surface of the tooth 19 of the lid 7 presses against the inclined surface of the portion 21, bringing about an angular movement in a clockwise direction of the lever 20 until the end of the inclined surface exceeds the tooth 19.
- the shaft 24, and consequently the lever 20, are loaded by elastic means (not represented, since they are in themselves known) so as to move in a counterclockwise direction and return into their respective initial positions, thus obtaining reciprocal engagement between the tooth 19 and the portion 21.
- the lid 7 is completely closed, as may be seen in Figures 1 and 7.
- the user In order to charge the detergent, the user must press the button 16.
- the said pressure on the button 16 will bring about an angular movement of the shaft 10 and consequently of the top arm 11, countering the elastic reaction of the spring 14 with respect to the bottom arm 12.
- the end tooth of the arm 11 is thus released from the respective engagement seat 13, thus bringing about release of the assembly made up of the lid 7 and the articulation element 4 with respect to the body 2.
- the button returns, along with the shaft 10, to its original position by means of the action of the spring 14.
- the assembly 4, 7 moves angularly into the position illustrated in Figures 2 , 3 and 8.
- the said movement may come about automatically if a spring similar to the one designated previously by 9 is provided ( Figures 3 and 5) between the element 4 and the body 2 in a position corresponding to at least one of the pins 5.
- the above angular movement is obviously enabled by the fact that the element 4 is hinged in its bottom area by means of the pins 5 to the body 2.
- the rounded surface of the tooth 19 of the lid 7 is of considerable importance since, during angular movement, it remains in contact with, and slides over, the portion 21 of the lever 20.
- the lid 7 is pushed towards the body 2 so as to bring the tooth of the arm 11 of the shaft 10 back into a position of engagement in the respective seat 13 (see again Figure 6) , the said engagement being achieved substantially by movements of the various components which are opposite to the movements previously described with reference to the step of manual release .
- the user can close the door of the dish-washer and start the washing cycle according to known procedure.
- part of the water that splashes inside the washing chamber of the dishwasher can penetrate inside the compartment 6 so as to bring about partial dissolution of the detergent through the gap, visible in Figure 7, between the end of the chute portion 3A and the gasket 18.
- the inside of the compartment 6 will, instead, be isolated from any splashing of water that might possibly strike the dispenser 1, as a result of the action of sealing exerted by the gasket 18 in combination with the lip 4A and the end of the chute portion 3A.
- the control system of the dish-washer electrically supplies the actuator means aimed at producing angular actuation of the shaft 24 and hence of the lever 20.
- the lid 7 is automatically induced to open, with an angular movement about the horizontal axis defined by the tubular seats 8 of the element 4, which are inserted in respective holes present on the two opposite sides of the lid 7.
- the lever 20 returns into its original position as a result of the action of the respective elastic means referred to previously.
- the top part of the assembly 4, 7 remains in a fixed position in that it is anchored to the body 2 by engagement of the tooth provided on the arm 11 in the respective seat 13 (see Figure 6) .
- the condition of complete opening of the lid 7 may be seen in Figure 4.
- Opening of the lid 7 enables the detergent to drop inside the washing chamber of the dish-washer. Dropping of the detergent is facilitated by the inclined conformation of the bottom wall of the compartment 6. Complete removal of the detergent from the compartment is then obtained by the jets of liquid coming out of the sprays inside the dish-washer. In the condition where the lid 7 is completely open (see Figure 4) , the said sprays can impinge directly on the compartment 6. The washing cycle then proceeds according to modalities in themselves known.
- the dispenser 1 according to the invention can also be advantageously applied to washing machines equipped with a loading door that tips or turns over forwards or can be tipped or turned backwards.
- the user of the dish-washer is afforded the possibility of carrying out charging of the compartment 6 with detergent according to two different procedures.
- the user in any case guaranteed the possibility of carrying out charging with detergent also in a traditional way, i.e., with the door completely open or with the door horizontal (i.e., the dispenser 1 will be in the position of lie illustrated, for example, in Figure 4) .
- charging of the detergent will be carried out according to known procedures, if need be opening the lid 7 using the arm 25 of the lever 20.
- Figures 11 and 12 illustrate a preferred embodiment of the invention, adcording to which the dispenser is provided with indicator means aimed at facilitating proper dosing of the detergent.
- the same reference numbers used in the previous figures are once again used to indicate elements that are technically equivalent to the ones described previously. Note that, in the case illustrated in the said figures, the spring 9 is not housed in a respective tubular seat 8.
- Figure 11 illustrates a situation of charging the detergent similar to the situation illustrated in Figures 3 and 8, i.e., with the door of the dish-washer half open or in a prevalently vertical position.
- indications of dosage of detergent represented in the specific case by a transverse mark or notch 27A indicating the maximum level of detergent, with a respective wording "MAX" designated by 27B.
- Figure 12 illustrates, instead, a situation of charging with detergent with the door of the dishwasher substantially horizontal, i.e., with a lie of the dispenser 1 similar to the one illustrated in Figure 4.
- the dispenser 1 can be mounted indifferently on doors that turn over, on sliding doors, or on constantly vertical surfaces, it being possible for charging with detergent to be carried out in any case in a convenient and easy position for the user.
- the items making up the invention are few in number, present a simple structure, and can be easily manufactured by processes of moulding of thermoplastic material .
- the movements involved in charging the machine with a dose of detergent and in obtaining subsequent delivery of the detergent are of an elementary nature.
- a further advantage relates to the fact that the body 2 itself of the dispenser 1 according to the invention can be used also for the purposes of making traditional dispensers, i.e., ones equipped just with a lid hinged only in its top part directly to the body 2.
- the body 2 will be advantageously equipped with lateral holes, in the top part of the housing 3, in which respective hingepins of the lid can be inserted directly.
- the space for containing the detergent will be greater than the space available according to the invention, in so far as it is defined directly by the central depression of the housing 3 (in the case of the application of the present invention, as illustrated previously, said central depression is in part occupied by the compartment 6) .
- the sealing system on the lid 7 may be modified if need be.
- the engagement/release system afforded by the lever 20 and by the corresponding actuation means can be the same as the one described previously.
- the articulation element 4 may be in the form of a simple fork or U-shaped element, i.e., without the full central part, in which, in the attached figures, the compartment 6 is defined.
- the space for containing the detergent would be therefore formed directly by. the central depression of the housing 3.
- the element 4 could also be replaced by two parallel arms, articulated in the respective bottom parts to the body 2 by means of pins similar to the ones designated by 5, there being instead articulated, to the top part of said arms, the lid 7, by means of a system of articulation or hinging similar to the one illustrated in Figures 2 to 5.
- the shaft 10 could also constitute the pin for turning of the lid 7 with respect to the intermediate element 4.
- Figure 13 illustrates a further possible variant embodiment of the system of engagement/release for the top part of the assembly made up of the element 4 and the lid 7 with respect to the body 2.
- a slide element i.e., an element that can move linearly, designated as a whole by 30, which is mounted on the body 2 in a position corresponding to the top end of the housing 3 so as to be able to slide in a direction transverse to the housing itself.
- the slide element 30 has two engagement teeth, which can engage in respective seats 32, defined in opposite side appendages or flaps 4B of the articulation element 4.
- the slide element 30 When pressed on one of its side portions, designated by 33, the slide element 30 is able to slide, against the action of a spring 34, in the direction for releasing the teeth 31 from the respective seats 32 and thus obtain the release of the assembly 4 , 7 with respect to the body 2.
- engagement is instead obtained by pressing the assembly 4 , 7 towards the body 2 , so as to produce, via interference of the portions 4B of the element 4 with an inclined top surface of the teeth 31, a lateral displacement of the slide element 30, against the action of the spring 33, said displacement enabling subsequent engagement of the same teeth 31 in the respective seats 32.
- the dispenser 1 could be provided with end-of-travel means, according to a design in itself known, which operate for limiting the movement of opening of the assembly 4, 7, which comes about for the purpose of "vertical" charging of the detergent (see, for example, Figures 3 and 11) , the aim being to prevent the bottom wall of the compartment 6 from exceeding the chute portion 3A, with the consequent risk that some detergent may penetrate or be erroneously poured between the intermediate element 4 and the seat 3 in the body 2.
- the intermediate element 4 is provided with openings 29 along the sides of the lip 4A, the aim being to allow, during washing of the dishes, passage of water also between the intermediate element 4 and/or the compartment 6 and the body 2 so as to favour removal of any possible residue of detergent that might be present therein.
- the openings . 29 provided along the two opposite sides of the lip 4A are also provided with fins or deflectors to enable better conveying of the flow of water towards the rear part of the compartment 6.
- the intermediate element 4 is laterally coupled to the body 2 so as to be able to perform angular movements about an axis of rotation that is substantially perpendicular to the axis of rotation of the lid 7, the latter being hinged, in its top part, to the same element 4, as described previously.
- the intermediate element 4 in one side of the seat 3, there are provided two brackets, designated by 35, which co-operate with respective cylindrical appendages or pins 5 defined in the homologous side of the intermediate element 4 so that the latter is hinged to the body 2.
- the lid 7 is, instead, hinged to the element 4 in its top part, as in the case of the embodiments described previously.
- the bottom-engagement system of the lid 7 is made up of two parts.
- a first part, carried by the body 2 comprises the transmission element 23 and the shaft 24 (for reference, see Figure 4 and Figures 7 to 9) , where the front end of said shaft, which projects in the seat 3, defines a key designated by 36 in Figure 15.
- the second part of the engagement system which is carried by the intermediate element 4, is similar to the lever designated previously by 20, which here carries an opening at the rear, the said opening being designated by 37 in Figure 15.
- the key 36 can be fitted when the assembly 4, 7 is brought into the respective closing position.
- the lever 20 will, of course, be operative for keeping the lid 7 engaged to the element 4 when the assembly 4, 7 is open in the "vertical" charging position.
- the engagement arrangements 9-16 or 30-34 could be replaced by other suitable retention means designed to keep the intermediate element 4 in the closing position with respect to the body 2.
- the said means could, for instance, be of the friction type and be arranged in a position corresponding to the intermediate elements 4 or the pins 5.
- the said friction means could be made in the form of disks made both on the body 2 and on the intermediate element 4 and having toothed surfaces which face one another and mesh with one another.
- the aforesaid disks would be designed to bend as a result of the elasticity of the thermoplastic material of which they are made so as to disengage or unmesh under the manual action of opening and closing and then engage together with one another in the new position since they have a force of mutual engagement such as to maintain the intermediate element 4 in position.
