Description

OBJECT OF THE INVENTION

The present invention can be included in the technical field of industrial cleaning devices. More specifically, the present invention is framed within carpet cleaning devices, especially car mats.

BACKGROUND OF THE INVENTION

Some machines and elements are known from the state of the art that allow the cleaning of automobile carpets but are not suitable for use in the industrial sector due to their complexity, especially in the initial preparation of carpet placement in them. The operation is also complex and after cleaning it is difficult to remove the carpets avoiding the formation of marks or moisture stains on them. Thus, when these machines are used in the industrial sector, the times used by operators to perform these carpet washing tasks are very high. This implies high costs.

The most important difficulties associated with washing and drying car mats are marked by the high flexibility of this type of carpet. As they are made with flexible polymers, they adapt very easily to the environment in which they are placed. In the cleaning devices known from the state of the art part of the carpet is in contact with the ground with what marks remain on the carpet and this makes cleaning impossible.

Another important technical problem presented by devices known in the state of the art is the fact that, when several carpets are washed at the same time, some of the carpets can receive part of the dirty water that drips or drains from other adjacent carpets with that new spots appear on it. Something similar occurs during the drying process since the water that comes out of some carpets can reach the adjacent carpets, wetting them. This causes the carpets that receive the water take much longer to dry and additionally moisture spots may appear on them.

DESCRIPTION OF THE INVENTION

The present invention solves the technical problem posed, by means of a cleaning device specially designed for cleaning in the carpet industry. With this device cleaning can be done in a short time, in addition to avoiding marks and dirt produced by accumulation of water on the surface of the carpet or by contact with other surfaces. Furthermore, in this device the electrical and electronic elements that in the devices of the state of the art are cause of failures with the consequent loss of time by the workers have been eliminated. The device is especially suitable for cleaning car mats.

The device essentially comprises a support that allows at least one wash basket to be held inside the carpet to be washed. The support comprises a vertical central bar from which at least one pair of horizontal bars extending parallel to the ground. Each washing basket of the device is placed between two horizontal bars, being joined by its upper part to one of them and by its lower part to the other.

In an embodiment of the invention in which several washing baskets are placed on the same vertical, the central bar of the support extends forming an "S" during its travel in the vertical direction such that two independent vertical planes are formed. At least two horizontal bars split from each straight section of the central bar so that each washing basket is in one of these independent planes.

This allows the water that falls from cleaning the carpet placed in the upper wash basket to fall directly to the floor and not over the wash basket that is below it. This avoids the appearance of stains on the carpet in the lower wash basket. The water that falls from the cleaning of each of the washing baskets falls

in the plane where the washing basket itself is located.

The central bar is responsible for providing stability to the support to withstand the forces caused by the weight of the carpets and the pressure of the water jet that is released for cleaning said carpets.

In a preferred embodiment of the invention the support is made of a metallic material such as iron, steel or aluminum. The metallic materials are suitable for use in the device because they have a high mechanical strength and it is easy to form parts with them so that the support of the invention can be manufactured in a simple way.

If the support is made of iron, it is necessary to apply an anti-rust base to avoid oxidation that would cause permanent contact with water and that would weaken the support. Another possible option is to manufacture the support can in steel, which has a high mechanical resistance when subjected to tensile and compression stresses thanks to the chemical contribution of its components. In addition, the steel has a great facility for its treatment and the possibility of joining with other steels by welding.

The washing basket is the support element for the carpets, which are introduced inside the carpet at the top. It has a V-shaped side profile that is defined by two converging sections in a lower edge and has a cage-like constitution with metal mesh on both sides of the basket, which has a large free surface and very little contact surface With the carpet to be cleaned. The upper part of the metal mesh is curved to facilitate the introduction of the carpet inside the basket.

The free surface of the metal mesh allows the water jet (or an aqueous cleaning solution) to pass to the carpet. In addition, a certain clearance is maintained between the basket and the carpet, thus avoiding horizontal and vertical markings that the metal structure could leave on the carpet.

Inside the wash basket the carpets are in a substantially position

straight, thus preventing them from folding over themselves, but if they have some mobility inside the basket, which helps reduce washing marks by decreasing direct contact between the carpet and the mesh surfaces.

The connection of the washing baskets to the horizontal bars is carried out by means of bearing bearings installed in said horizontal bars in correspondence with axes that start respectively from the upper face and the lower face of the washing basket. Thus, the washing basket is rotatably linked to the horizontal bars, allowing the washing basket to rotate along its transverse axis. The use of bearing bearings allows the complete rotation of the washing basket with the application of a small force. This turning force is the pressure of the water used for cleaning.

In one embodiment of the invention, the device comprises blocking elements to stop the rotation of the washing baskets. Said blocking element is a plate, preferably rectangular in shape, which has at one of its ends an extension that leads to a threaded ring that is linked to a threaded rod. The blocking elements are attached to the horizontal bars at the top of the baskets. From these horizontal bars, at the end that is far from the central bar, a flat extension arises at the end of which is a threaded cylinder. The threaded rod of the locking element is placed inside said threaded cylinder.

The threaded rod protrudes from the end of the threaded cylinder and rests on a notch in the lateral end of the basket. This ensures the blocking of the position of the basket in front of the turn. When pressure water is fired on the plate of the blocking element, said plate moves causing the displacement of the threaded rod that performs the release.

In a preferred embodiment of the invention the blocking element is made of plastic to avoid problems of oxidation and blockage of the parts. The most recommended plastics to be used in the blocking element are thermoplastics, such as PET or PVC, since they have a very good response to impact and friction.

Likewise, the device comprises in an embodiment of the invention an anti-return element that avoids the rebound effect of the washing baskets when the rotation occurs. It comprises a tilting movement element that allows the basket to pass in the direction of rotation and prevents the basket from passing in the opposite direction, which could occur as a result of the rebound of the basket in the blocking element.

In a particular embodiment of the invention, the device may comprise a manual turning system that allows the device to be used in places where high pressure washing systems are not available. It is a lever that is attached to the rod so that when the lever is operated manually, the rod moves and leaves the notch on which it was supported, so that it allows the basket to rotate. So you can get the basket spin manually to access the back of the carpets quickly and efficiently.

Also, in one embodiment of the invention, the basket comprises external support means that allow the carpets to be held on the outside of the basket where they are accessible with a brush. In this way you can clean all the stains that require a physical rub such as a brush. In a preferred embodiment of the invention there are two external support means in each basket, both on the same face of the basket, each of them at an upper end thereof.

Additionally, the device of the invention can be used with external drying means that allow to reduce carpet downtime due to its humidity, thus reducing the time for reassembly in the vehicles. The drying means comprise a regulating nozzle that distributes the air of a turbine that is installed in the vicinity of the equipment. In these drying means the air is injected at a sufficient pressure and flow rate to cause the elements to dry.

PREFERRED EMBODIMENT OF THE INVENTION

Next, a preferred embodiment of the invention is described with the aid of Figures 1 to 5 above.

The cleaning device of the present invention specially designed for cleaning in the industrial area of vehicle mats. It allows to reduce the appearance of marks on the carpets, especially due to the contact of the carpet with a certain surface during washing and drying operations, and allows to avoid the appearance of stains on said carpets. In addition, the device is easy to use for users, which is especially important when used in industrial cleaning where minimizing operating times is essential.

The device of the invention comprises a support with a vertical central bar (1) from which horizontal bars (2) emanate that extend in a direction parallel to the ground as seen in Figure 1. This support allows to support at least a washing basket (3) inside which a carpet is placed to proceed to its

cleaning. In a preferred embodiment said carpet is a car carpet.

In an exemplary embodiment of the device, the central bar (1) is 60 mm in diameter with a thickness of 1.44 mm. The support is anchored to the ground to ensure its resistance. Specifically in this embodiment, the support is attached to the ground by means of four screws distributed symmetrically on a 16x16 cm square base.

The support is preferably manufactured in a metallic material such as steel or iron. If it is iron, it is necessary to apply an antioxidant layer to avoid the adverse effects of prolonged contact with water that would cause the support to oxidize.

The horizontal bars (2) extend two to two since each washing basket (3) is placed between two parallel horizontal bars (2) that are in the same vertical plane and are rotatably linked to them. When washing baskets (3) are placed on the same horizontal, each one is placed on the side of the central bar (1) between its corresponding horizontal bars (2) that will extend from the center bar I (1).

In an exemplary embodiment of the invention, the support comprises a central bar (1) with a single section, from which two horizontal bars (2) in one direction and two horizontal bars (2) in the opposite direction, to the same height. A washing basket (3) is placed between each pair of horizontal bars (2). It is a simple washing device in which there are two washing baskets (3), placed horizontally at a single height, allowing the complete washing of two carpets quickly and efficiently.

If you want to place several washing baskets (3) on the same vertical, an important problem arises related to the washing baskets (3) that are at the bottom. When the pressurized water (or aqueous wash solution) is fired for washing the carpets that are in washing baskets (3) on the same vertical, the water used for the upper washing basket (3) falls on the basket wash (3) lower so that the carpet in it can be stained with dirty water that falls.

In addition, during the drying time, water may continue to fall from the upper wash basket (3) on the lower one, so that it does not dry out so quickly and moisture spots or other stains caused by water falling from the water can appear. upper basket (3).

To solve this problem, in an embodiment of the invention, the support comprises the central bar (1) divided into a first section (4) extending in a vertical direction, a second curved section (5) in the form of "S "and a third section (6) extending in a vertical direction in a plane different from that of the first section (4). Figure 1 shows the embodiment described here.

Two pairs of horizontal bars (2) start from said first section (4) and from the third section (6). A washing basket (3) is placed between each pair of horizontal bars (2). In the first section (4) two baskets (3) are placed in the same horizontal and in the third section (6) there are two other baskets (3) placed in the same horizontal. The baskets (3) of the first section (4) and the baskets (3) of the third section (6) are not in the same vertical plane, but thanks to the second section (5) of the central bar (1) there is a gap between said vertical planes. It is a double washing device that allows the washing of four carpets directly. This embodiment is especially designed for companies that have a high volume of rugs for washing, such as car rental companies.

At least two horizontal bars (2) start from the first section (4) between which a washing basket (3) is placed and remains in a vertical first plane. At least three other horizontal bars (2) start from the third section (6) between which another washing basket (3) is placed and which remains in a vertical second plane that is separated from the first vertical plane by the second section (5) from the center bar (1).

In this way the water that falls from the cleaning or drying of the carpet placed in the washing basket (3) that is at the height of the third section (6) falls directly to the floor without wetting or staining the carpet of the basket washing (3) that is at the height of the first section (4) because thanks to the design of the central bar (1) it is in another vertical plane

Independent.

The washing baskets (3) comprise a cage with metal mesh (7) that has a V configuration that is defined by two converging sections in a lower edge (8) as shown in Figure 2. The lateral ends (9) of the washing baskets (3) are flat sheets that extend up to a height greater than the metal mesh (7) of the cage. Said lateral ends (9) are joined by their lower part through the lower edge (8) and are joined by their upper part through an upper end

(10) which is a flat sheet parallel to the bottom edge (8).

The free space between the upper end (10) and the metal meshes (7) is the hole through which the carpets are introduced and removed in the washing baskets (3). The free end (11) of the metal meshes (7) is slightly curved towards the outside of the washing basket (3) to facilitate said introduction and removal as can be seen in Figure 2.

The carpets remain in a substantially straight position inside the washing baskets (3) and have some mobility inside said baskets (3). With the device of the invention the folding of the carpet on itself is avoided, thus avoiding the appearance of wrinkles. Likewise, the fact that the carpet has some mobility within the washing basket (3) allows to reduce direct contact between the carpet and the metal mesh (7) so that the appearance of marks is also avoided.

The washing baskets (3) are joined to the horizontal bars (2) by means of connecting elements. Said connecting elements comprise shafts (12) that emanate from the upper end (10) and from the lower edge (8) of the washing baskets (3), and bearing bearings arranged in the horizontal bars (2) in the that the axes (12) are introduced. The position of the axes (12) coincides with the transverse axis of the basket (3). This type of joint allows the washing baskets (3) to rotate on their own transverse axis. With a small force applied, the baskets (3) can make a complete turn.

The device also includes blocking elements that can be seen in the

Figure 3. Specifically, there is one for each wash basket (3), formed by a plate

(13) which has a flat extension at one of its ends that leads to a threaded ring (14) that is linked to a threaded rod (15). The blocking element is linked to the device through the horizontal bars (2) that remain at the top of the washing baskets (3).

From said horizontal bars (2), a flat extension (16) with a threaded cylinder (17) flows from the end that is furthest from the central bar (1). Inside the threaded cylinder (17) the threaded rod (15) of the locking element protruding from the end of the threaded cylinder (17) is inserted. This is clearly seen in Figure 5.

The part of the threaded rod (15) that protrudes is supported by a notch (18) arranged for this purpose at the lateral ends (9) of the washing basket (3). This blocks the turning movement of the baskets (3).

Pressurized water is used during the carpet washing process, when one of the faces of the carpet is already clean and the opposite face has to be cleaned, the user points the pressurized water towards the plate (13) causing its movement . The movement of the plate (13) causes the displacement of the threaded rod (15) and it is removed from the notch (18) leaving the washing basket (3) free to rotate. When it stops pointing at the plate (13) with the pressurized water, it returns to its initial position. In an exemplary embodiment of the invention, it is sufficient for the plate (13) to move 37 ° so that the release of the basket (3) occurs and therefore its free rotation.

In this way, when the washing basket (3) has traveled half a turn, the threaded rod (15) protruding again from the threaded cylinder (17) is hooked in the notch (18) of the side end (9) of the basket (3), blocking your turn.

In one embodiment of the invention, the device further comprises an anti-return element that avoids the rebound effect that may occur when the half turn is finished, the basket (3) collides with the locking element and the threaded rod (15) engages in the notch (18). The non-return element can be clearly seen in Figure 5. There is an anti-return element for each wash basket (3) and it is placed on one of the horizontal bars (2) to which the wash basket (3) is attached. Cornprende a notch (18) on which an elernento with tilting movement (19) with a stop (20) is arranged in one of its ends such that it swings only in one direction. By tilting it allows the basket (3) to pass in the direction of rotation and blocks the passage of the basket (3) in the opposite direction by the stopper (20).

In a particular embodiment of the invention. The device may comprise a manual turning lever (21) when it comprises locking elements for use in installations where there are no pressurized water sistern. In this case, the device has a rnnnnnnnnn lever for each plate (13). Figures 4 and 5 show a manual rotation lever as described here.

The manual rotation lever (21) has an "L" configuration and starts from the stem (15). In a particular embodiment of the invention, the lever (21) extends in a direction parallel to the lateral end (9) of the basket (3) and comprises a 90 ° rotation towards the basket (3).

As the manual rotation lever (21) starts from the rod (15), when the lever is moved (21), the rotation of the rod (15) that leaves the notch (18) on which it is resting slows the rotation of the basket (3) so that the basket (3) can now rotate freely. The limit of movement of the manual rotation lever (21) is marked by a stop, disposed at the side end (9) of the basket (3) below the notch (18), as can be seen, for example, in the Figures 2 and 3. This stop marks the end of the movement of the manual rotation lever (21) since when the manual rotation lever

(21) reaches the top, the notch (18) of the rod (15) is released and the free rotation of the basket (3) occurs.

In another embodiment of the invention, the device comprises external support means (22) that allow the carpets to be held in an accessible part for cleaning means. Thus, in case it is necessary to clean the carpets by physical rubbing with an abrasive element, such as a brush, it can be done on the device itself.

In a specific embodiment, the outer support means (22) comprises a first fastener (23) that allows its attachment to the basket (3), and a second fastener (24), attached to the first fastener fastening (23), which allows the fastening of the carpet.

In this exemplary embodiment, the first fastener (23) has a spiral configuration and acts as a spring. The connection between the basket (3) and the external support means (22) is carried out by means of the first fastener (23) as it is placed around a metal mesh rod (7) of the basket (3).

The second fastening means (24) is placed on the outside of the basket (3), and has a rectangular or square configuration, which adapts to the grid size of the metal mesh (7) so as not to cover more surface than the covered by the mesh. This second clamping means (24) is rotated on its connection with the first clamping means (23). In this way, to hold the carpet outside the basket (3) and proceed to cleaning operations using abrasive elements, such as a brush, the second fastening means (24) is moved, moving its end away from the basket (3 ), the carpet is placed in the space that is free, and the second fastening means (24) that returns to its original position is released, pressing the carpet against the outside of the basket (3) and holding it in that position.

In a specific embodiment of the invention the outer support means (22) is a 1 mm thick rod so that the space hidden by the element is reduced so that it does not affect the cleaning of the carpet when it is placed in the inside the basket (3). Generally, two external support means (22) will be available for each basket being placed on the same face of the basket, at its two upper ends.

Additionally, drying means comprising a turbine that generates an air current and a nozzle having an upper mouth connected to said turbine can be had. The air is injected at a sufficient pressure and flow to cause the elements to dry. In an exemplary embodiment of the invention a three-phase helical fan of 3Kw of electric power is used which

It generates a flow of 6,120 m3 / h with a speed of 1410 rpm.
