Definitions
- the present invention relates to a blower filter system with a blower filter device, comprising a blower, a filter holder and a hose connection, a filter for insertion in such a blower filter system and a method for determining the pneumatic resistance of a blower filter system.
- fan filter systems are used for respiratory protection situations. These usually have a blower filter device in which a blower for generating a substantially constant volume flow of air is arranged.
- a respiratory protection device for example in the form of a respiratory mask or a respiratory protective hood, on his head.
- the volume flow is from the blower filter device conveyed through a hose to the respiratory protection device.
- the sucked air is sucked through a filter in the filter holder, in order to achieve a corresponding protective effect.
- the filters differ in particular with regard to the substance to be filtered.
- filters are to be distinguished in gas filters and particle filters as well as combination filters, which can filter out gases and particles.
- combination filters in the particle filter portion
- particle filters With combination filters (in the particle filter portion) and with particle filters, the filter performance decreases over the time in which the filter becomes entangled with particles. This reduction in capacity of the filter is associated with an increased pressure loss, so over the useful life of such a particulate filter or such a combination filter, an ever higher pressure loss is provided by the filter.
- the blower is readjusted in order to be able to provide a constant volume flow along a characteristic curve despite the increased pressure loss.
- a disadvantage of known blower filter systems is the display of the residual capacity.
- the residual capacity of a filter is usually calculated by the determined pressure loss of the entire blower filter system.
- a determination of the pressure loss and thus the pneumatic resistance of the entire fan filter system is created as input and compared with the capacity of the fan.
- the difference between these two parameters forms a basis for the calculation of the residual capacity.
- the maximum value of the maximum blower value eg 10 mbar
- a fixed parameter eg, about 3 mbar
- blower filter system having the features of claim 1, a filter with the features of claim 1 1 and a method having the features of claim 16.
- Further features and details of the invention will become apparent from the dependent claims, the description and the drawings , In this case, features and details that are described in connection with the fan filter system according to the invention, of course, also in connection with the filter according to the invention and the method according to the invention and in each case vice versa, so that with respect to the disclosure of individual aspects of the invention is always reciprocal reference or can be.
- An inventive blower filter system has a blower filter device with a fan, a filter holder and a hose connection for the connection of a respiratory protection device by means of a hose.
- An inventive blower filter system is characterized in that the filter holder is designed for receiving a filter, on which a color coding with a specific for a parameter of the filter, in particular for the pneumatic resistance of the filter color is arranged.
- the blower filter device has an optical sensor device for detecting different colors of the color coding. The color coding thus allows an encoding of a parameter specific to the filter.
- blowers are to be understood as relevant parameters. Such a parameter thus influences the functioning of the fan.
- the color of the color coding encodes the pneumatic resistance of the filter.
- the color of the color coding is in particular exactly one or substantially exactly one color.
- different colors can also be used in a common color coding, which, for example, can be arranged next to one another. The reading of such different colors can be performed with the same common sensor device or with different sensor devices.
- different color positions are used for different parameters for their encoding.
- inventive quality in addition to the pneumatic resistance and other parameters, in particular blower relevant parameters, in a color coding or in adjacent color codings are provided.
- the combination of different colors in a color coding may be specific to one parameter, in particular the pneumatic resistance.
- a direct readout of the pneumatic resistance of the filter can now be carried out.
- a control unit of the fan filter system which is designed to determine and / or calculate the residual capacity of the filter
- a real pneumatic resistance of the filter is now used as a basis for the calculation.
- the color coding by the optical sensor device of such a control unit would give the information that the filter has a pneumatic resistance of approximately 7 mbar, for example, in the empty and still unloaded state.
- the maximum fan power of about 10 mbar is stored in the control unit, so that a difference can be calculated, which can be attributed to the filter of about 3 mbar as total capacity.
- the Calculation of the residual capacity is now based on this maximum available difference between pneumatic resistance and maximum performance of the fan. Accordingly, the residual capacity in accordance with the invention is now determined and displayed in a real way and in particular unadulterated specifically for the respective filter. This leads to a much more accurate and in particular unadulterated display of the residual capacity and thus to increased acceptance by the user. In particular, in this way it is achieved that a possibly incorrect treatment of filters, in the form of a wrong definition as rejects, is avoided.
- the design of the filter holder according to the invention is to be understood as meaning that a geometrical correlation of the two components is defined by the filter holder and the filter.
- the filter intake can be Having threaded means or snap-locking means to position the filter in a defined relative position to the blower filter device and / or fastened. Due to this defined relative positioning, a defined relative position of the color coding also takes place. In particular, this defined relative positioning to a defined relative position to the optical sensor device to understand.
- the color coding is arranged virtually automatically by inserting and fixing the filter in the filter holder at a position at which the optical sensor device can also perform a recognition of this color coding.
- the filter holder has corresponding fastening and / or positioning means, which automatically guides the color coding of the filter when it is inserted into the filter holder in the desired relative position.
- the optical sensor device is arranged with a corresponding correlated relative position in the blower filter device and designed for the corresponding recognition of the different colors of the color coding.
- the sensor device is thus adapted to the nature of the colors of the color coding, in particular to the distinctive character of different colors of the color coding with different pneumatic resistances of different filters.
- the pneumatic resistance of the filter is to be understood as meaning the defined pressure drop as it flows through this filter. This pressure loss depends on the design of the filter, in particular on the packing density of the corresponding filter material. The denser the filter is packed or the longer its flow path, the greater the pneumatic resistance of such a filter will fail. In other words, the greater the filter performance, a denser packing is necessary and thus an increased pneumatic resistance of the filter is produced. For determining the residual capacity of this pneumatic resistance of the filter is crucial. However, in addition to the determination of the residual capacity of the filter nor the manner of the connected hose or the connected respiratory protection device can be considered.
- the fan filter system in particular in the fan filter unit, has a control unit which is designed to carry out the determination of the residual capacity.
- a display device for example in the form of a display, can be arranged on the blower filter device in order to visually display the remaining capacity for the user.
- the filter is usually consumable, which is designed for use in a layer or in an operational situation of the fan filter system. The service life of such filters are thus in the range of one to several hours. Then the filter is disposed of as used material and replaced with a new, fresh filter.
- a fan filter system according to the invention can resort to a very cost-effective and easily produced coding in the form of color coding.
- the color coding can be printed or glued on and bring little cost in the production and in the coding of the respective filter.
- existing production systems can continue to be used due to the simplicity of this color coding.
- Existing filters can of course also be retrofitted with color codings according to the invention.
- the optical sensor device is preferably formed with sensor means, e.g. can be configured as a light emitter, as a light receiver and / or as a light guide.
- the optical sensor device brings with it sensor means, which enable the recognition steps in physical terms for the recognition of the color of the color coding. These include, on the one hand, the recognition of a position in the color space and its intensity as well as the light conduction between the recognition means and the color coding. In particular, the physical concept of the reflection of light at the color coding is used.
- a filter with a color coding is recorded with a specific color for the pneumatic resistance of the filter.
- a respiratory protection device with a hose connected to the hose connection, so that the blower filter system completes for the Insert is formed.
- the filter is consumable material, which can preferably be exchanged for a working layer of the user of the blower filter system.
- the individual filters each represent a free state in which they are still unoccupied, ie unused.
- the residual capacity of the filter will decrease as a result of use in the fan filter system, and accordingly the filter will be coated with particles.
- the pneumatic resistance is increased by the occupancy and thus in the manner described a calculation of the reducing residual capacity possible.
- the optical sensor device has at least one light source for the emission of light and at least one light receiver for the reception of reflected light.
- the light source is particularly inexpensive, for example, as an LED formed.
- the emission of light can be done in different colors, in particular, as will be explained later, with white light.
- the light receiver is, for example, a photoelectrically active element, which is able to evaluate reflected light in terms of intensity and / or position in the color space.
- the optical sensor device itself becomes active, so that the optical sensor device for detecting the color of the color coding can be used independently of an environmental situation.
- the color coding of the filter in the inserted state is located in the filter receptacle in a sealed-off area, then no external light is obtained there. Rather, a defined in this case dark or darkened environment is created, which provides a defined lighting situation of color coding by known manner of emitting light from the light source.
- a fundamental characteristic of the reflection behavior can be predetermined by the material, the arrangement and the surface of the color coding and stored, for example, in a control unit of the fan filter system.
- the light receiver can take into account these basic optical parameters of geometric factors and reflection behavior in the evaluation of the received reflected light. This exact definition of the optical boundary conditions leads to the fact that the accuracy in determining the color coding is further increased.
- the intensity of specific light may be sequentially perceived in an RGB color spectrum by the light receiver. It is also possible that the light receiver is made more complex in order to split the received reflected light in terms of its intensity in the individual color components.
- the light source is designed for the emission of white light, in particular as an LED.
- the light receiver is preferably designed as an RGB color sensor in order to divide the received type of reflected light into the individual primary colors and to be able to specifically determine the respective intensity.
- information about the mixed color of a control unit becomes available in order to be able to determine the actual color of the color coding, in particular to be able to calculate it.
- Such an embodiment is particularly inexpensive and simple in terms of the light source.
- the determination step can be carried out particularly quickly, since only a single short-term irradiation with white light and the corresponding reception of the reflection must be performed.
- the light receiver is preferably designed as a broadband sensor.
- the light source has at least three light sources with different light colors for the emission of differently colored light.
- the three basic colors can be used, for example, as lighting means.
- the light receiver may preferably be designed more cost-effective, since no decomposition of the reflected light into the individual primary colors is more necessary. Rather, the irradiation with three different colors in a sequential manner, that is, one after the other, directly performs a splitting of the reflected light into the respective light components. Thus, this splitting takes place optically and does not have to be done later by electronic evaluation. A simpler and faster training of the sensor as a light receiver is possible in this way.
- the filters which can be accommodated in the filter receiver have color coding with different colors, the different colors being spaced from one another in a color space substantially equidistant, in particular exactly equidistant.
- a color space is, for example, the so-called RGB color space (red green / blue).
- RGB color space red green / blue
- a color space thus defines precisely a color mixture of a color, in particular in a three-dimensional manner by means of three position coordinates. If different colors are used for different pneumatic resistances of different filters, then in a first step, any color choice can be used for the color of the respective color coding.
- the distance between the individual different colors is preferably chosen to be particularly large.
- the spacing in the color space between the different selected colors is substantially the same for all the colors of a color coding system used, so that the recognition of the different colors with respect to their distinctiveness brings about the same effectiveness and thus the same security for all the different colors of the color system of color codings , This increases the recognition accuracy and reduces the susceptibility to errors.
- the recognition accuracy in the case of an optical sensor device according to the invention is thus influenced only to a limited extent or not at all.
- the optical sensor device has at least one light guide, which is designed for guiding light in the direction of color coding.
- a light guide is formed for example of a plastic material or a fiberglass material and in particular constructed as a so-called TIR body (Total Internal Reflection). It has an input area and an output area, so that the light emitted by the light source can be coupled in via the input area and the coupled-in light can be coupled out again via the output area.
- Other optical devices such as lenses, reflectors or diaphragms can be used as additional components of the optical sensor device for Will be provided.
- the light guides serve to make the applicability of the optical sensor device, in particular the individual sensor means, simpler and more free. In this case, different numbers of optical fibers can be provided.
- a Y-shaped branch of a light guide is also possible in order to achieve a further cost reduction and component reduction.
- the blower filter device has a hose recognition device for detecting a type of hose, which is specific for a pneumatic resistance, of a hose connected to the hose connection.
- hoses are specific to the respective respiratory protection device. So there is a specific tube, e.g. for a respirator and another specific tube, e.g. for a respirator.
- all types of tubing which are specific to the respective respiratory protection device have one and the same mechanical interface to the respective hose connection of the blower filter device.
- the hose recognition device is preferably likewise designed to be automated and recognizes at the specific hose type which respiratory protection device is currently in use.
- a tube recognition device leads to a further improved residual capacity indication and determination of the respective residual capacity.
- different pneumatic resistances of different respiratory protective devices based on the specific tube in the determination of the residual capacity can now also be considered.
- the hose-recognition device is also designed as an optical sensor device for detecting different colors of a hose color coding, which is arranged on a hose with a specific color for the type of hose and thus the pneumatic resistance is.
- the described quality of the invention is also applicable to a tube detection device.
- the hose-detecting device preferably independent and separate sensor means, so its own light transmitter and its own light receiver on.
- the respective color coding of the hose is annular in order to ensure a free rotatability of the hose to the hose connection and at the same time to provide a point-like monitoring by means of the optical sensor device.
- the rotational position it is ensured that in the case of an annular formation of the tube color coding, it is thus always possible to determine the color of the color coding by exact position correlation with the optical sensor device of the tube recognition device.
- the hose recognition device as an electronic sensor device for reading an electronic label, in particular an RFID tag, with respect to a pneumatic resistance which is arranged in the hose is formed.
- the hose is unlike the filter is usually not a consumable, but can be used over many uses.
- a more cost-intensive solution with an RFID tag can be used here as well.
- the RFID label or the electronic label is arranged in the region of the coupling on its inner side for protection against mechanical influence or unintentional removal.

- the specific color of the color coding can be achieved by subtractive color mixing.
- color systems are conveniently available and beyond clearly definable in terms of a three-dimensional color space in the recognition of the color of the color coding.

- the color coding is formed as an adhesive label and attached to a surface of the filter.
- the adhesive labels can be printed cheaply and easily and then simply attached by gluing.
- the color coding is printed directly on the filter during its production.
