Description

[0001] The present invention relates to the field of washing parts and in particular to a device for drying parts, wherein the drying device simultaneously dries the part and the inner walls of the chamber of the device in which the part is dried.

[0002] Parts cleaning is a crucial step in the manufacturing process across numerous industries, including automotive, precision mechanics, electronics, watchmaking, IT, aerospace, and medical technology. Part cleaning is particularly essential after machining operations, before surface treatments are applied to mounting surfaces, or before parts are assembled.

[0003] For example, after machining processes, cleaning steps with detergent solutions or other solutions are required to degrease machine parts. Once these cleaning steps are complete, the machine parts must be dried during a drying step. This drying step must be as effective and fast as possible to minimize product manufacturing time.

[0004] One initial solution considered for carrying out this drying step is to allow the part to drip dry on a support after the washing step. However, this solution is time-consuming, its effectiveness is not optimal, and it causes problems such as deterioration with certain parts.

[0005] Another solution considered for carrying out this drying step is to use nozzles for spraying air onto the part to be treated, as described in US patent application US2012080063. This patent application describes a washing device comprising a capsule-shaped washing chamber, wherein the upper part of the capsule includes first nozzles for spraying a washing fluid onto the part to be treated and second nozzles for spraying air onto the part to be treated after the washing phase for the purpose of drying.

[0006] However, this washing and drying device does not allow for optimal drying time, and the part to be treated cannot be dried in a targeted manner, since the nozzles that enable drying of the part are only located on the upper part of the capsule and are only directed towards the part to be treated.

[0007] Another device for drying a part after a washing process is a workpiece treatment device as described in European patent application EP2156905. This patent application describes a device that has a treatment chamber in which a part is washed and then dried by means of a nozzle device that rotates around the part to be treated and sprays a cleaning fluid (washing phase) and then air (drying phase) onto the part to be treated, the nozzles of the nozzle device being directed towards the part to be treated.

[0008] However, this washing and drying device does not allow the part to dry in an optimal time, and since the nozzles are only directed at the part to be treated, the parts can become damp again during subsequent treatments due to water still contained in the chamber.

[0009] From DE 29 08 112 A1, a positive developer device for removing the light-insensitive coating material from switch plates is known, wherein residues in a treatment chamber are removed by rinsing with deionized water and the switch plates and chamber interiors are subsequently dried using heated nitrogen. Corresponding nozzles are statically arranged in the cylindrical treatment chamber.

[0010] EP 1 640 077 A2 discloses a treatment device for cleaning and / or drying workpieces, comprising a rotatably mounted workpiece carrier and a nozzle arrangement, wherein a relative movement is provided between the nozzle and the workpiece carrier to enable effective treatment. The relative movement is circular and the chamber is cylindrical.

[0011] DE 38 26 399 C2 discloses a cleaning system for scales with a drying function. Nozzles for drying air are arranged on a rotary arm that can perform a circular movement around the scale.

[0012] The present invention aims to overcome the disadvantages of the prior art by proposing a device for drying a part which simultaneously dries the part to be treated and the inner walls of the treatment chamber, thereby reducing the drying time of the part, particularly after a washing process, wherein the device for drying a part can be integrated into a washing and drying machine or can be a stand-alone drying device.

[0013] The present invention enables targeted, more effective drying of the part to be treated and a reduction in the time required for this operation by drying the part using nozzles that blow out air, and by simultaneously drying the inner walls of the treatment chamber of the device using openings that blow out air, wherein the inner walls of the treatment chamber optionally have liquid collection devices that direct the collected liquid towards a liquid outlet of the device.

[0014] The present invention also relates to a washing machine which has such a more effective device for drying a part, which furthermore reduces the overall duration of the washing and drying cycle of the washing machine.

[0015] The present invention also relates to a method for drying a part, in which such a device is used for drying a part.

[0016] The present invention relates to a device for drying a part, comprising a treatment chamber having a side wall which is closed at both ends with a bottom and an upper wall to form a container whose interior is accessible via an opening which can be tightly closed, a liquid outlet which is connected to the treatment chamber to collect the liquid which has been produced during the drying of the part, a power supply, an air supply which supplies a means for blowing air in the treatment chamber so that it blows air onto the part arranged inside the treatment chamber, the device being characterized in that it further comprises a means for blowing air onto the inner walls of the treatment chamber, wherein the means for blowing air onto the part is a part drying tube equipped with nozzles which is connected to the air supply via a rotary connection.The drying tube is rotated around the part such that the nozzles remain oriented towards the part during each rotation of the drying tube. The device further comprises guide means, wherein the guide means include a guide plate with a circular opening in its center and a rail arranged at its outer edge. A rotary joint is arranged in the center of the opening, wherein the guide means further include a disk assembly slidably mounted at the edge of the opening. The rotary joint and the disk assembly are connected to each other by a horizontal arm. The drying tube is slidably mounted on the rail. The disk assembly and the drying tube are connected to each other by a second horizontal arm, wherein the second horizontal arm is attached to the drying tube via a pivot joint.

[0017] This results in a reduction of drying time and an increase in drying efficiency, whereby the inner walls of the treatment chamber of the device for drying a part and the part to be treated are dried simultaneously, thereby reducing the saturation vapor pressure in the treatment chamber.

[0018] According to a particular feature of the invention, the means for blowing air onto the inner walls of the treatment chamber is a wall drying tube, wherein the wall drying tube is connected to the air supply via a rotary connection and comprises a longitudinal section in the same direction as the height of the side wall, which is moved in a ring-like fashion on the inner side wall of the treatment chamber, wherein the length of the longitudinal section of the wall drying tube preferably corresponds to the height of the side wall or is of the same order of magnitude, wherein the air from the air supply is blown out through one or more openings which are arranged on the wall drying tube and which, during a revolution of the wall drying tube inside the treatment chamber, remain rotated in the direction of the inner side wall of the treatment chamber.

[0019] The wall drying tube can be extended at both ends of its longitudinal section with two tubes perpendicular to its longitudinal section, so that it also dries the floor and upper wall of the treatment chamber without exceeding the scope of the present invention. If the nozzles are oriented towards the floor of the treatment chamber, a downward spiral can advantageously form when the tube is rotated, which simplifies the drainage of the liquid.

[0020] This results in a targeted blowing of air onto the inner side wall of the treatment chamber, which can shorten the time required for effective drying of the part.

[0021] According to a particular feature of the invention, both the means for blowing air onto the part and the means for blowing air onto the inner walls of the treatment chamber are located on one and the same common tube, which is connected to the air supply via a rotary joint and comprises a longitudinal section in the same direction as the height of the side wall, wherein the common tube is rotated around the part, the length of the common tube preferably corresponding to or being of the same order of magnitude to the height of the side wall of the treatment chamber, wherein air from the air supply is blown onto the part by nozzles arranged on the side of the common tube opposite the part, and air from the air supply is blown onto the inner walls of the treatment chamber by one or more openings arranged on the side of the common tube.the openings are held opposite the inner side wall of the treatment chamber when the common tube is rotated around the part.

[0022] The space required for the blowing elements is thus reduced, which improves the compactness of the device for drying a part. Furthermore, since both blowing elements are arranged on the same common tube, only a single rotating element around the part needs to be provided and connected.

[0023] Without departing from the scope of the present invention, the partial drying tube and the wall drying tube can be independent; in particular, the partial drying tube can be stationary, and the wall drying tube can rotate in a ring-like fashion on the inner side wall of the treatment chamber. The two tubes can be supplied with one and the same air supply or with two different air supplies: a compressed air supply for the partial drying tube and a supply of normal air (blower) for the wall drying tube.

[0024] According to a particular feature of the invention, the part drying tube and / or the wall drying tube of the means for blowing air onto the part and the inner walls of the treatment chamber is an annular tube that moves around the part in a vertical or lateral back-and-forth motion.

[0025] A mechanical device that causes the tube to move vertically back and forth can enable the tube to cover the entire area to be dried, thereby improving drying efficiency and speed due to the improved displacement and movement of the water droplets.

[0026] According to a particular feature of the invention, the wall drying tube or the common tube of the means for blowing air onto the inner walls of the treatment chamber has a single opening in the form of a slit that runs along the length of the tube and remains rotated towards the inner side wall of the treatment chamber when the wall drying tube or the common tube is rotated inside the treatment chamber in order to dry the wall and / or the wall and the part.

[0027] According to a particular feature of the invention, the nozzles of the part drying tube or the common tube of the means for blowing air onto the part are aligned in a longitudinal direction of the tube.

[0028] According to a particular feature of the invention, the air supplied by the air supply is compressed air or air blown out by a blower.

[0029] By blowing compressed air at a high throughput onto the part to be treated and onto the inner walls of the treatment chamber, the effectiveness of drying the part can be increased.

[0030] According to a particular feature of the invention, liquid collection devices are formed on the inner side wall of the treatment chamber, wherein the liquid collection devices are in the form of a slot that extends in the direction of the height of the treatment chamber and opens outwards from the treatment chamber to a channel that directs the liquid thus collected towards the liquid outlet.

[0031] The liquid present on the inner side wall of the treatment chamber is blown by the air blowing device onto the inner walls of the treatment chamber and into the liquid collection devices. From there, it is guided by the trough towards the liquid outlet. This reduces the time the liquid remains on the inner side wall of the treatment chamber, thus shortening the drying time.

[0032] According to a particular feature of the invention, the side wall of the treatment chamber has a square, rectangular or round shape in cross-section.

[0033] The invention also relates to a washing machine with a power supply, a washing solution supply and a device for drying a part, as previously defined, characterized in that it further comprises a means for washing the part arranged inside the treatment chamber of the device for drying a part, wherein the means for washing the part is a tube which is connected to the washing solution supply via a rotary connection and is rotated around the part, wherein a washing solution from the washing solution supply is sprayed onto the part by nozzles arranged on the tube.

[0034] The device for drying a part can thus be integrated into a washing machine, thereby reducing the overall duration of the washing and drying cycle.

[0035] According to a particular feature of the invention, the tube of the means for washing the part is the same as the common tube of the means for blowing air onto the part and for blowing air onto the inner walls of the treatment chamber, wherein the washing solution is sprayed from the same nozzles as the air or from different nozzles.

[0036] The space required for the blowing and washing components is thus reduced, which improves the compactness of the washing machine. Furthermore, since both the blowing and washing components are arranged on the same common tube, only a single rotating mechanism needs to be provided and connected.

[0037] The washing solution of the washing machine can be a detergent solution, oil, soluble oil, water or demineralized water or solvents, without leaving the scope of the present invention.

[0038] The object of the invention is also a method for drying a part, characterized in that it consists of drying a part to be dried, which is placed in a treatment chamber forming a closed container of a treatment device as defined above, by spraying air onto the part and simultaneously spraying air onto the inner walls of the treatment chamber.

[0039] The drying process can be used alone or in combination with a prior washing step or a vacuum drying step.

[0040] The technical effect of simultaneously drying the walls of the treatment chamber and drying the part is a noticeable reduction in the drying time of the part.

[0041] If the washing step and the drying process take place in the same treatment chamber, drying the inner wall of the treatment chamber ensures better cleanliness of the treatment chamber for subsequent washing / drying, and thus better washing and drying of the parts.

[0042] Of course, several parts can be dried and / or washed and dried simultaneously in the same treatment chamber without leaving the scope of the present invention.

[0043] To better illustrate the subject matter of the present invention, a preferred embodiment is described below in an illustrative and non-limiting manner with reference to the accompanying drawings.

[0044] These drawings contain: Fig. 1 a perspective view of a device for drying a part according to a first modification of the embodiment of the present invention; Fig. 2 a sectional view of the device for drying a part of Fig. 1; Fig. 3 a top view of the device for drying a part of Fig. 1; Fig. 4 a top view of a device for drying a part according to a second modification of the embodiment of the present invention; Fig. 5 a top view of a device for drying a part according to a third modification of the embodiment of the present invention; and Fig. 6 a block diagram of a washing and drying machine according to the present invention.

[0045] With reference to Fig. 1, Fig. 2 and Fig. Figure 3 shows a device 1 for drying a part according to a first modification of the embodiment of the invention.

[0046] The device 1 for drying a part comprises a treatment chamber 2 which has a side wall 3 which is closed at both ends with a bottom 4 and an upper wall 5, so that a closed container is formed.

[0047] The walls of treatment chamber 2 have been shown with dotted lines so that the interior of treatment chamber 2 can be clearly seen.

[0048] In the illustrated embodiment, the side wall 3 of the treatment chamber 2 has a square cross-sectional shape, although this shape is in no way restrictive.

[0049] It can therefore be concluded that the side wall 3 of the treatment chamber 2 could also have a rectangular or round shape.

[0050] The side wall 3 can be made of plastic, glass, or metal.

[0051] The floor 4 and the upper wall 5 of the treatment chamber 2 can be made of plastic, glass, or metal.

[0052] The interior of the treatment chamber 2 is accessible via a door 6, which is formed on one of the surfaces of the side wall 3 and which can be tightly closed by means of a seal (not shown) arranged around its circumference. Although a tight seal of the door 6 is not strictly necessary, it is preferred.

[0053] A part 7 to be dried, shown as a non-limiting example in the form of a cylinder, is arranged inside the treatment chamber 2 on a part carrier 8, the part carrier 8 comprising a horizontal flat upper part 8a forming a plate on which the part 7 to be dried is arranged, and a vertical cylindrical part 8b forming a foot connecting the horizontal flat upper part 8a to the center of the bottom 4 of the treatment chamber 2.

[0054] Below the treatment chamber 2 is a liquid outlet 9 for collecting the liquid that has formed during the drying of the part 7, wherein the liquid outlet 9 is connected to the center of the bottom 4 of the treatment chamber 2 via holes 4a formed in the bottom 4.

[0055] It should be noted that the bottom 4 of the treatment chamber 2 is preferably, but not necessarily, slightly inclined towards its center, with the center of the bottom 4 being lower in relation to the edges of the bottom 4 so that the liquid produced during the drying of the part 7 can run towards the center of the bottom 7, so that it can subsequently flow out through the holes 4a into the liquid outlet 9.

[0056] The liquid outlet 9 is a hollow cylindrical tube made of plastic, but it can also be made of metal.

[0057] The device 1 for drying a part also includes an air supply 10 and an electric motor 11, which is supplied by a (not shown) power supply, which are arranged above the treatment chamber 2, as well as a means for blowing air 12 onto the part 7 and the inner walls of the treatment chamber 2, which is arranged inside the treatment chamber 2, wherein the air supply 10 supplies air to the means for blowing air 12 and the electric motor 11 causes the means for blowing air 12 to rotate around the part 7.

[0058] The air supply 10 provides the means for blowing air 12 with compressed air or air blown out by a (not shown) blower.

[0059] The air blowing means 12 has a vertical drying tube 13 comprising nozzles 14 oriented towards part 7 and openings 15 oriented towards the inner side wall 3 of the treatment chamber 2, and a guide means 16, wherein the drying tube 13 is rotated around part 7 by the guide means 16 such that, during one rotation of the drying tube 13 around part 7, the nozzles 14 remain oriented towards part 7 and the openings 15 remain oriented towards the inner side wall 3 of the treatment chamber 2, whereby air from the air supply 10 is blown from the nozzles 14 onto part 7 and from the openings 15 onto the inner side wall 3 of the treatment chamber 2.

[0060] The length of the drying tube 13 preferably corresponds substantially to the height of the side wall 3, so that the effectiveness of drying the inner side wall 3 through the openings 15 is increased. The more similar the length of the drying tube 13 and the height of the side wall 3 of the treatment chamber 2 are to each other, the more effective the drying is.

[0061] The nozzles 14 of the drying tube 13 are aligned in a longitudinal direction of the drying tube 13.

[0062] It should be noted that the drying tube 13 could include a single opening in the form of a slot extending along the length of the drying tube 13 to dry the inner side wall 3 of the treatment chamber 2.

[0063] The drying tube 13 is preferably made of metal, but can also be made of plastic or a composite material.

[0064] The guide means 16 of the means for blowing air 12 has a square guide plate 17 with rounded edges, which has a circular opening 18 in the middle of it, and a rail 19 which is arranged on the outer edge of it, wherein the guide plate 17 is arranged on the upper wall 5 of the treatment chamber 2 (covered by it), and a rotary joint arrangement 20 which is arranged in the middle of the opening 18 of the guide plate 17 and to which air is supplied by the air supply 10.

[0065] The guide means 16 further comprises a disk arrangement 21, which includes two disks 21a, 21b with a rolling bearing 21c between the two disks 21a, 21b, wherein the disk arrangement 21 is slidably attached to the edge of the opening 18 of the guide plate 17 via a roller support 21d, which is attached to the upper part of the upper disk 21a.

[0066] The rotary joint assembly 20 and the disk assembly 21 are connected to each other via a horizontal arm 22, so that the rotation of the rotary joint assembly 20 causes the rotation of the disk assembly 21 at the edge of the opening 18 of the guide plate 17.

[0067] The upper end of the drying tube 13 has a roller bracket 23 which is slidably attached to the rail 19 of the guide plate 17.

[0068] The disk assembly 21 and the upper end of the drying tube 13 are connected to each other via a second horizontal arm 24, the second horizontal arm 24 being attached to the upper end of the drying tube 13 via a pivot connection 25, so that the rotation of the disk assembly 21 at the edge of the opening 18 of the guide plate 17 causes the drying tube 13 to rotate on the rail 19 of the guide plate 17.

[0069] The rotation of the rotary joint assembly 20 thus causes the drying tube 13 to rotate along a square orbit around the part 7 while simultaneously moving along the inner side wall 3 of the treatment chamber 2, whereby the nozzles 14 of the drying tube 13 blow air onto the part 7 and the openings 15 of the drying tube 13 blow air onto the inner side wall 3 of the treatment chamber 2. The system of the invention makes it possible to keep the nozzles 14 permanently pointing towards the part 7 and the openings 15 pointing towards the side wall 3 as the tube rotates around the part 7.

[0070] The liquid located on part 7 and on the inner side wall 3 is blown away by the drying tube 13 and then falls by gravity onto the floor 4 of the treatment chamber 2, subsequently through holes 4a formed in the floor 4 of the treatment chamber 2 into the liquid outlet 9.

[0071] It should be noted that the device 1 for drying a part could have a means for blowing air onto the part 7 and a means for blowing air onto the inner side wall 3 of the treatment chamber 2, which are independent of each other, wherein the means for blowing air onto the part has a tube equipped with nozzles which is rotated around the part 7 such that the nozzles remain turned towards the part 7 as the tube rotates around the part, and the means for blowing air onto the inner side wall 3 has a tube equipped with openings, distinct from the tube of the means for blowing air onto the part 7, which is moved in an annular fashion on the inner side wall 3 of the treatment chamber 2, wherein the openings are turned towards the inner side wall 3 of the treatment chamber 2 as the tube rotates inside the treatment chamber 2.

[0072] Furthermore, the system for rotating the tube is not limited to the system described in connection with the figures, and within the scope of the present invention any system for rotating the tube is considered, the advantage of which is that during rotation of the drying tube a substantially equal distance can be maintained between the drying tube and the side wall of the treatment chamber, thereby ensuring uniform drying.

[0073] With reference to Fig. Figure 4 shows a device for drying a part according to a second modification of the embodiment of the invention.

[0074] According to this second modification of the embodiment of the invention, the device 1 for drying a part has two liquid collection devices 26a, 26b, which are arranged on two opposite surfaces of the side wall 3 of the treatment chamber 2, wherein the liquid collection devices 26a, 26b are in the form of a slot which extends outwards from the treatment chamber 2 towards the height of the treatment chamber 2 to a channel which directs the liquid thus collected during drying with the means for blowing air 12 towards the bottom 4 of the treatment chamber 2, wherein the liquid then flows towards the liquid outlet 9 of the device 1 for drying a part.

[0075] With reference to Fig. Figure 5 shows a device 1 for drying a part according to a third modification of the embodiment of the invention.

[0076] According to this third modification of the embodiment of the invention, the device 1 for drying a part has two liquid collection devices 27a, 27b, which are arranged at two opposite corners of the side wall 3 of the treatment chamber 2, wherein the liquid collection devices 27a, 27b are in the form of a slot which extends outwards from the treatment chamber 2 towards the height of the treatment chamber 2 to a channel which directs the liquid thus collected during drying with the means for blowing air 12 towards the bottom 4 of the treatment chamber 2, wherein the liquid then flows towards the liquid outlet 9 of the device 1 for drying a part.

[0077] It should be noted that the device 1 for drying a part could have a single liquid collection device or more than two liquid collection devices arranged on the side wall 3 of the treatment chamber 2 or optionally in at least one of its corners, without leaving the scope of the present invention.

[0078] With reference to Fig. Figure 6 shows a block diagram of a washing machine 100 according to the present invention.

[0079] The washing machine 100 comprises a treatment chamber 101, a power supply 102, a detergent solution supply 103, an air supply 104, a rotary connection 105 and a detergent solution outlet opening 106.

[0080] It should be noted that although in this embodiment the washing solution of the washing machine 100 is a detergent solution, the washing solution could also be oil, soluble oil, water, demineralized water or solvents without leaving the scope of the present invention.

[0081] The power supply 102 supplies the treatment chamber 101 with electricity, and the detergent solution supply 103 and the air supply 104 supply detergent solution or air to the rotary connection 105, whereby the rotary connection 105 then supplies detergent solution or air to the treatment chamber 101.

[0082] The treatment chamber 101 of the washing machine 100 has inside it a means for washing a part and a means for blowing air onto the part and the inner side wall of the treatment chamber 101.

[0083] The means for blowing air is identical to the means for blowing 12 of the device 1 for drying a part according to the present invention.

[0084] The washing device consists of a tube that is rotated around the part, spraying a detergent solution onto the part from nozzles arranged on the tube.

[0085] The rotary connection 105 rotates the air blowing agent and the washing agent, while simultaneously supplying detergent solution to the washing agent and air to the air blowing agent.

[0086] It should be noted that the tube of the means for washing can be the same as the tube of the means for blowing air onto the part and the inner side wall of the treatment chamber 101, wherein the washing solution is sprayed onto the part from the same nozzles as the air or from other nozzles, without leaving the scope of the present invention.

[0087] A part to be treated is placed inside the treatment chamber 101 of the washing machine 100, then a detergent solution is sprayed onto the part from the detergent solution supply by the washing agent, which is set into rotation around the part, and subsequently air is blown onto the part and the inner side wall of the treatment chamber 101 by the air blowing agent, which is set into rotation around the part, with the liquid produced during drying being drained via the detergent solution outlet opening 106.

[0088] The detergent solution circuit within the tube can be the same as the circuit for blowing air onto the part. The circuit for blowing air onto the chamber walls is independent to prevent detergent solution from splashing onto the chamber walls during the washing phase. The circuit for blowing air onto the part and the circuit for blowing air onto the chamber walls can be supplied by the same air source, such as a compressed air source. Alternatively, the circuit for blowing air onto the part can be supplied by a compressed air supply, while the circuit for blowing air onto the chamber walls can be supplied by a blower for cost reasons.

[0089] It should be noted that the device 1 for drying a part could also be integrated into other devices, for example hardening oil machines, machine tools or dishwashers.

[0090] The device 1 for drying a part according to the present invention can be used according to a method for drying a part 7, characterized in that it consists of drying the part 7, which is placed in a treatment chamber 2 forming a closed container, by spraying air onto the part 7 and simultaneously spraying air onto the inner walls 3 of the treatment chamber 2.
