Definitions
- the present invention relates to a device for cleaning cavities of a ventilation system, in particular of a vehicle, by means of a cleaning agent, and to a method for producing the device.
- the cleaning requirement for the environmental cleaning of vehicle cabin air filters is usually carried out by means of chemical-mechanical cleaning.
- a chemical cleaning fluid is introduced to dissolve and bind organic material and the dirt is removed mechanically, for example with the help of a cloth.
- This multi-stage cleaning process often leads to long, complex cleaning cycles, since in a first step the chemical cleaning fluid is introduced directly into the filter box using a spray probe and the mechanical cleaning is then carried out by wiping it out by hand using a cloth guide.
- a device for cleaning cavities of a ventilation system for example a cabin air filter system or an air filter box of a ventilation system
- a cleaning agent for example a cabin air filter system or an air filter box of a ventilation system
- the device has a receiving section for receiving a cleaning agent container and a cleaning section, wherein the cleaning section forms a support frame which is configured in such a way that that a pocket-shaped cleaning cloth can be put over the cleaning section so that an inner volume (within a put-on cleaning cloth) can be formed.
- the cleaning section is coupled to the receiving section in such a way that a cleaning agent of the cleaning agent container, which can be fastened in the receiving section, can flow from the receiving section into the inner volume.
- a method for producing a device for cleaning cavities of a ventilation system, in particular of a vehicle, using a cleaning agent comprises providing a receiving section for receiving a cleaning agent container and providing a cleaning section, wherein the cleaning section forms a support frame which is configured such that a pocket-shaped cleaning cloth can be put over the cleaning section so that an internal volume can be formed. Furthermore, the method comprises coupling the cleaning section to the receiving section such that a cleaning agent of the cleaning agent container, which can be fastened in the receiving section, can flow from the receiving section into the internal volume.
- a ventilation system For efficient ventilation and air conditioning of a vehicle, a ventilation system has a large number of housings or ventilation ducts with cavities through which a desired amount of air can be directed into predetermined areas of the vehicle. At one or more locations of the ventilation system, (pollen) air filters are provided in particular, which must be replaced in a predetermined maintenance cycle.
- the cavities of the ventilation system can be reached through smaller openings. Chemical cleaning agents can be introduced through these openings and mechanical cleaning elements, such as cleaning cloths, can also be introduced.
- the device according to the invention has a cleaning section which is designed with a support frame onto which a pocket-shaped cleaning cloth can be placed. The support frame stabilizes and thus carries the cleaning cloth, so that the cleaning cloth can be introduced together with the support frame, for example, into a cavity in the ventilation system in order to carry out mechanical cleaning.
- the support frame is designed to stretch the pocket-shaped cleaning cloth so that an inner volume (internal volume) can be formed.
- the support frame spaced apart an opposing front and rear flat cleaning section of the cleaning cloth.
- the width of the support frame with which the cleaning cloth is stretched is in particular less than 2 cm, in particular less than 1 cm, so that the support frame together with the cleaning cloth itself can be inserted into small ventilation openings or openings in filter boxes through which the hand of a user would not fit.
- the support frame can, for example, be attached to the receiving section in an articulated manner.
- the support frame can be designed to be elastically deformable in order to elastically adapt to certain shapes of the cavities of the ventilation system.
- the cleaning cloth consists in particular of a felt-like, fibrous or woven material.
- the cleaning cloth can, for example, be a microfiber cloth.
- the cleaning cloth can consist of an organic material, such as cotton.
- the cleaning cloth can consist of a plastic-like fabric.
- the device also has a receiving section.
- a cleaning agent container can be interchangeably accommodated in the receiving section and fixed in a predefined position.
- the cleaning agent container in particular has a cleaning liquid which can be dispensed in the form of a spray, aerosol or foam, for example.
- the receiving section can simultaneously form a handle of the device. The user can grip the receiving section and, for example, handle the device in such a way that the cleaning section can be inserted into the cavity to be cleaned.
- the receiving section is coupled to the cleaning section in such a way that the cleaning agent can exit the cleaning agent container and flow into the interior volume of the cleaning section.
- the cleaning agent thus wets and moistens the cleaning cloth.
- the cleaning agent container can, for example, contain the cleaning agent at a pressure of 0.5 bar to 12 bar.
- the cleaning agent container also has an outlet tube or a riser pipe with a diameter of 0.5 mm to 10 mm. Since the support frame spans the cleaning cloth and the interior volume in the pocket-shaped cleaning cloth is thereby formed, the cleaning agent reaches the inner surfaces of the cleaning cloth over a large area, so that it is soaked with the cleaning agent homogeneously and evenly over the entire surface.
- the cleaning section can now be inserted into the cavity to be cleaned, thus allowing chemical and mechanical cleaning to be carried out simultaneously.
- the cleaning cloth is automatically soaked in cleaning agent so that the cleaning agent can be applied to the surfaces to be cleaned in the cavities.
- the cleaning cloth is stabilized by the support frame so that the user can carry out mechanical cleaning by pushing the cleaning section together with the cleaning cloth over the surfaces. It is sufficient if only the cleaning section and not the user's hand is inserted into the cavity to be cleaned. There is therefore no A two-stage cleaning process is necessary, after which cleaning agent is first applied and then mechanical cleaning is carried out with a cleaning cloth.
- a chemical and a mechanical cleaning step can be carried out simultaneously, so that efficient cleaning of cavities in a ventilation system is possible.
- it is easy to handle and protects against injuries when cleaning by hand due to sharp edges in the air filter box or the ventilation system.
- the receiving section has a clamping element which is designed to hold the cleaning agent container by means of a clamping fastening.
- the cleaning agent container can have a collar or a collar which can be introduced into the receiving section in an insertion direction.
- the clamping element clamps the cleaning agent container in place, for example by clamping the collar or the surface of the cleaning agent container.
- the clamping force is selected in such a way that due to the weight of the cleaning agent container, it cannot fall out of the receiving section, but a release force must be applied by the user in the opposite direction to the insertion direction.
- the cleaning cloth can be pulled over the support frame and then the cleaning agent container can be inserted into the handle or the receiving section.
- the cleaning agent container e.g. spray can
- the cleaning agent container empties and then moistens the cleaning cloth from the inside.
- the cleaning agent container is designed in such a way that the cleaning agent to be dispensed and under pressure is evenly distributed from the cleaning agent container into the
- the air flows into the inner volume of the bag-shaped cleaning cloth so that the inner surfaces of the cleaning cloth are evenly saturated with the cleaning agent over the entire surface.
- the cavities can then be cleaned chemically and mechanically.
- a new pollen filter can then be inserted into the clean environment.
- a spring element is provided in the receiving section, by means of which the clamping element can be pressed against the cleaning agent container.
- a spring force can generate the necessary clamping force in that the spring force presses the clamping element towards the cleaning agent container.
- the receiving section has a locking element which can be pressed into a recess in the cleaning agent container, for example by means of the spring element.
- the locking element can, for example, be arranged displaceably in the receiving section and can be pre-tensioned in the direction of the cleaning agent container by means of a spring force.
- a flow channel is formed between the receiving section and the cleaning section such that an outflow element of the cleaning agent container protrudes into the flow channel when the cleaning agent container is received in the receiving section.
- the flow channel has for example, a diameter between 0.5 mm (millimeters) and 10 mm.
- the cleaning agent container can, for example, have an outflow valve with a corresponding outlet tube.
- the flow channel in the receiving section can be arranged in such a way that when the cleaning agent container is fastened at the predetermined location in the receiving section, the outlet tube protrudes into the flow channel.
- the opening at the opening of the flow channel in the receiving section can be funnel-shaped, so that when the cleaning agent container is inserted into the receiving section, the outlet tube is centered in the flow channel and securely received.
- a sealing element for example a sealing ring made of rubber, can be provided in the opening of the flow channel in order to seal the receiving tube of the cleaning agent container with the wall of the flow channel.
- the support frame has at least two spaced support rods, which extend at a distance from one another from the receiving section along a longitudinal direction and are spaced along a transverse direction which runs perpendicular to the longitudinal direction.
- the support rods are designed in such a way that the cleaning cloth can be put over the support rods and the internal volume can be formed between the support rods.
- the longitudinal direction defines the direction of extension of the support rod from the receiving section in the direction of the opposite free end of the support rod.
- the transverse direction is defined perpendicular to the longitudinal direction, wherein the distance between the support rods is defined along the transverse direction.
- the support rods can extend parallel from the receiving section and thus have the same distance in the transverse direction at the receiving section and at the respective free end.
- the support rods can also extend in a V-shape from the receiving section such that the distance in the transverse direction between the support rods is smaller at the receiving section than at their free end.
- the support rods can extend from the receiving section such that the distance in the transverse direction between the support rods is greater at the receiving section than at their free end.
- the support rods can, for example, have a round or rectangular cross-section.
- the support rods can have a rectangular cross-section and be thin-walled or band-like.
- the distance between the upper side edge and the lower side edge defines the Distance between an upper surface and a lower surface of the cleaning cloth.
- At least one upper connecting web is provided between the upper side edges of the support rods, onto which a portion of the cleaning cloth can be placed.
- the connecting web thus prevents the cleaning cloth from falling between the support rods in the direction of the inner volume and thus disrupting the distribution of the cleaning agent.
- the connecting web serves to stabilize or stiffen the support rods.
- the connecting web can be made of the same material as the support rod and can be monolithic or integral with the support rods.
- At least one lower connecting web is provided between the lower side edges of the support rods, onto which a region of the cleaning cloth can be placed.
- the lower connecting web can be designed in a manner corresponding to the upper connecting web.
- a region of the internal volume is located between the upper connecting web and the lower connecting web. Since the cleaning cloth rests on the connecting webs, the upper connecting web and the lower connecting web prevent the cleaning cloth from folding up between the support rods and interrupting the internal volume.
- a corresponding connecting bar can also be attached centrally, i.e. between the upper side edge and the lower side edge of a support bar and, for example, in its course to the other support bar in the transverse direction, for example, an eyelet or a passage to form the internal volume, whereby the internal volume is not interrupted in the longitudinal direction.
- the lower connecting web and the upper connecting web run parallel to one another between the support rods.
- the connecting webs can have an angle to one another.
- the connecting webs can have an angle of 30° to 60°, in particular 45°, to one another.
- the lower connecting web and the upper connecting web are arranged offset from one another in the extension direction (i.e. in the longitudinal direction) of the support rods.
- an upper connecting web is arranged at a distance in the longitudinal direction from an adjacent lower connecting web. This ensures that the inner volume is formed in the longitudinal direction with few connection points over the entire longitudinal direction and reduces the risk of an upper surface of the cleaning cloth touching a lower cloth surface of the cleaning cloth and thus interrupting the inner volume.
- the receiving section and the cleaning section are manufactured integrally by means of injection molding. Accordingly, the receiving section and the cleaning section are formed integrally and in one piece.
- Cleaning section in particular the support frame, hinged to the
- Receiving section arranged such that the cleaning section relative to the receiving section is adjustable. This allows an angle to be formed between the receiving section and the cleaning section and makes operation easier, especially when cleaning cavities that are difficult to access. Accordingly, a joint can be provided between the receiving section and the cleaning section. The joint can, in the manner of a hinge, enable the cleaning section to be pivoted about an axis of rotation relative to the receiving section. Furthermore, a joint with two pivot axes or more (e.g. a ball joint) can also be provided.
- the cleaning section in particular the support frame, can have an elastic region such that the cleaning section is deformable relative to the receiving section. This also makes it possible to form an angle between the receiving section and the cleaning section.
- At least one hook element is formed on the support frame.
- the hook element is configured to hook into a material or into a receiving opening of the cleaning cloth and to secure it against slipping.
- the hook element forms a projection, so to speak, that extends from a surface of the support frame, in particular from the support frame in the direction of the cleaning cloth. This allows the hook element to penetrate into or pass through the cleaning cloth in order to create a positive connection, so to speak, and to secure the cleaning cloth against slipping relative to the support frame.
- the hook element can be made pointed at the free end in order to penetrate into the cleaning cloth for hooking.
- the cleaning cloth can have a receiving opening through which the hook element can reach.
- the free end of the hook element can also be made blunt in order to avoid injuries.
- the hook element can be made from the same material as the support frame and can be manufactured integrally and in one piece in a manufacturing process together with the support frame.
- the hook element can be made from a different material than the support frame and can be attached to the support frame, for example with an adhesive connection or a screw connection.
- the hook element can be designed as a projection with a straight (oval) shape.
- the hook element can be curved, for example sickle-shaped or L-shaped.
- a single hook element can be provided, but preferably two spaced hook elements, each of which is formed, for example, on opposing support rods.
- a plurality of further hook elements can also be attached to the support frame in order to attach the cleaning cloth.
- the hook element is used to hook onto the cleaning cloth, preventing the cleaning cloth from slipping. Because the cleaning cloth is slightly stretchable, it can be easily stretched when it is pulled over the support frame and pulled over the hook element.
- the hook element is formed on a support rod of the support frame and extends from the support rod, in particular in the direction of the receiving section.
- the cleaning cloth can thus be pulled over the support frame from the stabilizing web in the direction of the receiving section.
- the area of the opening of the cleaning cloth is then located after pulling it over over the support frame in an area between the receiving section and the cleaning section. If the hook elements now extend from the support frame in the direction of the receiving section, the cleaning cloth can be hooked in the area of the opening of the cleaning cloth, so that slipping of the cleaning cloth relative to the support frame can be effectively prevented.
- the hook element can also be attached to the stabilizing bar described above or to one of the upper or lower connecting bars and extend from them accordingly.
- the hook element is designed such that a free end of the hook element is located between two opposing support rods.
- the hooking with the cleaning cloth takes place at the free end of the hook element. If a free end of the hook element extends inwards according to the exemplary embodiment, i.e. in an area between two opposing support rods, the hook element is prevented from projecting outwards, i.e. outside the support rod, so that unwanted contact between the free end of the hook element and areas of the surface to be cleaned is prevented and scratches or other damage to the surface to be cleaned can be avoided.
- the device according to the invention enables reduced accessibility of housings of cabin air filters in motor vehicles.
- the adapted geometry of the device achieves a higher cleaning effect, especially in the area of the corners and edges of the filter box of a ventilation system.
- the device combines the requirements of a chemical-mechanical cleaning component within a cleaning tool.
- the use of the device according to the invention achieves an even distribution on the surface to be wetted.
- the use of the device according to the invention achieves an even removal of the dirt from the filter box.
- the device according to the invention can be designed in such a way that the size of the cleaning agent container is portioned for cleaning with the cleaning fluid and the use of a single-use cloth additionally ensures the hygienic result.

- Fig. 1 shows a perspective view and Fig. 2 a top view of a device 100 for cleaning cavities according to an exemplary embodiment of the present invention.
- the present invention relates to a device 100 for cleaning cavities of a ventilation system, in particular of a vehicle, using a cleaning agent.
- the device 100 has a receiving section 101 for receiving a cleaning agent container 600 (see Fig. 6) and a cleaning section 102, wherein the cleaning section 102 forms a support frame 103 which is configured such that a pocket-shaped cleaning cloth 700 (see Fig. 7) can be put over the cleaning section 102 so that an internal volume can be formed.
- the cleaning section 102 is coupled to the receiving section 101 such that a cleaning agent of the cleaning agent container 600, which can be fastened in the receiving section 101, can flow from the receiving section 101 into the internal volume.
- a pocket-shaped cleaning cloth 700 can be placed over the support frame 103.
- the support frame 103 stabilizes and thus carries the Cleaning cloth 700, so that the cleaning cloth 700 can be introduced together with the support frame 103, for example, into a cavity of the ventilation system in order to carry out mechanical cleaning.
- the device 100 also has a receiving section 101.
- a cleaning agent container 600 can be exchangeably received in the receiving section 101 and secured in a predefined position.
- the cleaning agent container 600 in particular has a cleaning liquid which can be dispensed, for example, in the form of a spray, foam or aerosol.
- the receiving section 101 is coupled to the cleaning section 102 in such a way that the cleaning agent can exit from the cleaning agent container 600 and can flow evenly into the inner volume of the cleaning section 102 up to the edge area.
- the cleaning agent thus wets and moistens the cleaning cloth 700 from the inside. Since the support frame 103 spans the cleaning cloth 700 and the inner volume in the pocket-shaped cleaning cloth 700 is thereby formed, the cleaning agent reaches the inner surfaces of the cleaning cloth 700 over a large area, so that it is soaked with the cleaning agent homogeneously and evenly over the entire surface.
- the support frame 103 has at least two spaced support rods 104, which extend at a distance from one another from the receiving section 101 along a longitudinal direction I and are spaced along a transverse direction q, which runs perpendicular to the longitudinal direction I.
- the support rods 104 are designed such that the cleaning cloth 700 can be put over the support rods 104 and the internal volume can be formed between the support rods 104.
- the longitudinal direction I defines the extension direction of the support rod 104 from the receiving section 101 in the direction of the opposite free end of the support rod 104.
- the support rods 104 run parallel from the receiving section 101 and have an equal distance in the transverse direction q at the receiving section 101 and at the respective free end.
- the distance between the upper side edge 301 and the lower side edge 302 defines the distance between an upper surface and a lower surface of the cleaning cloth 700 due to the support of the corresponding surfaces of the cleaning cloth 700.
- At least one lower connecting web 107 is provided, on which a portion of the cleaning cloth 700 can be placed.
- the lower connecting web 107 can be designed in accordance with the upper connecting web 106. Between the upper connecting web 106 and the lower connecting web 107 there is a portion of the internal volume. Since the cleaning cloth 700 rests on the connecting webs 106, 107, the upper connecting web 106 and the lower connecting web 107 prevent the cleaning cloth 700 from folding up between the support rods 104 and interrupting the internal volume.
- the lower connecting web 107 and the upper connecting webs 106 run parallel to each other between the support rods 104.
- a flow channel 402 is shown. Between the receiving section 101 and the cleaning section 102, the flow channel 402 is designed such that an outflow element 603 (see Fig. 6) of the cleaning agent container 600 protrudes into the flow channel 402 when the cleaning agent container 600 is accommodated in the receiving section 101.
- the cleaning agent container 600 is fixed in the receiving section 101, for example, by means of a clamping element 401. The cleaning agent can thus escape from the outflow element 603, flow through the flow channel 402 between the receiving section 101 and the cleaning section 102 and in particular through the inner volume up to the free end of the support rod 104 or the stabilizing web 105.
- the receiving section 101 has a clamping element 401 which is designed to hold the cleaning agent container 600 by means of a clamp fastening.
- the clamping element 401 is designed to be elastic, for example.
- the clamping element 401 can be designed, for example, as an elastic tab in the housing of the receiving section 101.
- two clamping elements 401 can be designed as tabs and can be formed opposite one another in the receiving section 101. The user can accordingly grasp the receiving section 101 and press the clamping elements 401 together.
- the clamping elements 401 have, for example, a clamping wedge which can apply a high pressing force to an internal cleaning agent container 600. As shown in Fig. 6, the clamping wedges can engage a collar 601 of the cleaning agent container 600 in order to improve the fixation.
- the cleaning agent container 600 can, for example, contain the cleaning agent at a pressure of 0.5 bar to 12 bar.
- the cleaning agent container 600 can have a collar 601 or a collar, which can be inserted into the receiving section 101 in an insertion direction.
- the clamping element 401 clamps the cleaning agent container 600 in place, for example by the clamping element 401 clamping the collar 601 or the surface of the cleaning agent container 600.
- the clamping force is selected such that due to the weight of the cleaning agent container 600, it cannot fall out of the receiving section 101, but a release force must be applied by the user in the opposite direction to the insertion direction.
- Fig. 7 shows a schematic representation of a cavity cleaning device 100 in which a cleaning cloth 700 is attached to the cleaning section 102, according to an exemplary embodiment of the present invention.
- the support frame 103 is designed to stretch the pocket-shaped cleaning cloth 700 so that an inner volume (internal volume) can be formed.
- the support frame 103 spaced apart an opposing front and rear flat cleaning section 102 of the cleaning cloth 700.
- the width of the support frame 103 in the width direction b, with which the cleaning cloth 700 is stretched, is in particular less than 2 cm, in particular less than 1 cm, so that the support frame 103 together with the cleaning cloth 700 can be inserted into even small openings in a filter box through which the hand of a user would not fit.
- the cleaning section 102 can now be introduced into the cavity to be cleaned and thus chemical and mechanical cleaning can be carried out simultaneously.
- the cleaning cloth 700 is automatically soaked with cleaning agent as the cleaning agent container 600 releases the cleaning agent into the interior volume and the cleaning agent is distributed throughout the entire interior volume.
- the cleaning cloth 700 has a receiving opening 901 through which the free ends 802 of the hook elements 801 can reach.
- the hook elements 801 have a sickle-shaped structure. If the free ends 802 are inserted through a receiving opening 901 of the cleaning cloth 700, the sickle shape reduces the risk of the cleaning cloth 700 unintentionally detaching from the hook elements 801.
