  • CONTAINER ASSEMBLY AND METHOD OF IDENTIFYING A CONTENT OF A CONTAINER
  • the present invention relates to a container for a cleaning appliance, an assembly and a method of identifying a content of a container.
  • Cartridges for automatic dosing machine typically had a rigid outer container and a connection portion for connecting to the machine to automatically dose a portion of the contents into the machine for use. Because the outer sides of the cartridge were rigid, it was necessary to have a valve structure somewhere on the cartridge body to allow air in as the contents were emptied. Such a valve sometimes resulted in leakage of the contents of the cartridge through the valve. This is especially a problem during transportation of cartridges.
  • the proposed solutions offered valves with rather complex structures which are more expensive and difficult to install.
  • CN113152032A discloses an intelligent identification device for a detergent box for automatic dispensing.
  • the system comprises a storage box with an identification code arranged on the storage box in a form of a plurality of positions and a switch assembly provided with a plurality of conductive components.
  • the corresponding conductive components are controlled to be connected or disconnected through the identification positions of the identification code of the storage box.
  • This often uses metallic materials for the conductive parts of the system, which are prone to corrosion.
  • parts of the system that are in contact with the cleaning product are required to be waterproof.
  • WO2021151727A discloses a detergent container for a cleaning device, a contacting device comprising conductive contacts, a method and a device for operating a cleaning device, and a cleaning device.
  • the detergent container has a housing and a contact area that is electrically conductive.
  • the contact area represents a content coding that represents the contents of the detergent container.
  • the contact area can be contacted using the contacting device in order to recognize the content coding.
  • Adding metallic parts to the detergent container is costly and the exposed conductive contacts are prone to corrosion.
  • WO 2007027809 A2 discloses a system which controls dispensing different chemicals received from containers at a plurality of ports. Each container has data thereon that identifies the chemical within the container. The system reads the data from each container to determine which port is associated with each chemical. When a given chemical is required, the system activates a flow control device coupled to the port associated with that given chemical, thereby supplying the given chemical to a consuming device.
  • DE10201770 A1 discloses a vehicle with a filling level sensor, which is arranged at least partially outside of a container for determining the filling level of a substance.

  • the number of and/or configuration of the at least one protrusion defines the one or more signals blocked between transmitter-receiver pairs.
  • the number of and/or configuration of signals blocked between transmitter-receiver pairs indicates contents of the container.
  • Such a system relies on a set number and configuration to identify if a container is present and then what container (or contents) is present. This allows for a user to insert a container into a cleaning system and not need to input the type of container or contents, thereby making for an easier user experience and eliminating user error.

  • a valve 60 is placed on or in the cap 50, and over the cap opening 54.
  • the valve 60 can have various forms, for example, a silicon cross piece, a duckbill valve, a deformable ball valve or other valve structure.
  • FIG. 1A-3C (or another embodiment of a cartridge) can be coupled with an identification device 120 configured to detect the contents of the cartridge 10 as shown in Figures 4A-4D.
  • Figure 4A shows a side view of an assembly 100 comprising a cartridge 10’ with identification protrusions and identification device 120.
  • the identification device 120 shown has a tubular connector 124 that is arranged to fit inside the insert 18 of the cap 50’. This can be a hollow connector to allow for flow out of cartridge 10’ in a similar manner to that described in relation to Figs. 1A-3C.
  • Engagement means 122 are used to connect the identification device 120 to the cleaning appliance, and transfer data or information, and possibly supply power to the identification device 120.
  • FIG 4B shows the front view of the identification device 120 with four transmitter-receiver pairs 110.
  • Each transmitter-receiver pair 110 includes one transmitter 112 and one receiver 114.
  • the transmitter 112 sends a signal 116 towards the receiver.
  • the signal 116 can be any type of signal that is suitable for contactless detection, for example, infrared, visible light or ultraviolet.
  • the transmitters 112 and the receivers 114 are configured such that only the receiver 114 of the specific transmitter-receiver pair 110 is able to detect the signal 116 of its paired transmitter 112 while the other receivers cannot.
  • the cap 50’ of a cartridge 10’ comprises at least one identification protrusion 102 to identify the contents of the cartridge 10’.
  • the one or more identification protrusions 102 extend from the cap 50’, and are positioned to fit between one particular transmitter-receiver pair 110 when the cartridge 10’ is connected to the identification device 120 to block signals sent from the transmitter to the receiver.
  • the cap 50’ includes three protrusions 102, which are positioned to block the transmission between three particular transmitter-receiver pairs 110.
  • the identification device 120 is configured to process signals 116 from the receivers 114 and convert them into digital states that can be read and/or interpreted by a processor (not shown). For example, if the receiver 114 received signal 116 from its paired transmitter 112, the identification device 120 generates digital state 1. On the other hand, if the signal 116 between the transmitter-receiver pair 110 is blocked by the identification protrusion 102, the identification device 120 generates digital state 0. This digital state information can then be sent to the processor.
  • the number and the configuration of signals blocked by the identification protrusions 102 creates an identification code for the contents of the cartridge 10’.
  • the configuration where all receivers 114 receive signals 116 from its paired transmitters 112 corresponds to the case when no cartridge 10’ is coupled with the identification device 120. Table 1
  • the cartridge 10’ containing detergent for coloured clothes can have two identification protrusions 102 arranged to be identified as Cartridge 6 from Table 1 by the processor, while the cartridge 10” containing fabric softener can have three identification protrusions 102 which are arranged to be identified as Cartridge 2 from Table 1 by the processor.
  • the cartridge 10”’ containing the detergent for white cloths can also have three identification protrusions but arranged to be identified as Cartridge 3 from Table 1 by the processor.
  • the processor and system can identify and dispense the correct types and amounts of the particular cartridges 10’, 10” or 10’” based on the identification system. In situations where no cartridge is detected, the system could be programmed to give a notification or alert such that a user knows they need to insert a cartridge.
  • Figure 4C shows the cap 50’ with three identification protrusions 102a, 102b, 102c and a missing protrusion 102d at the location intended for the fourth protrusion.
  • the cap 50’ is connected to the identification device 120 (note that the cap in that case is facing the identification device)
  • only the receiver 114d would be able to receive the signal 116d from its paired transmitter 112d, while all other signals 116 are blocked by the identification protrusions 102a, 102b, 102c as shown in Fig. 4D.
  • the identification code reads: State 0 (receiver 114a) - State 0 (receiver 114b) — State 0 (receiver 114c) - State 1 (receiver 114d), which corresponds to Cartridge 2 from Table 1.
  • the system then identifies this as the cartridge 10” containing fabric softener from the example above.
  • Such a system is a simple, yet effective method of identifying a particular cartridge (and/or the contents of the cartridge) in a washing machine or other cleaning appliance such as a dishwasher, carpet cleaner, mop, electric soap dispenser, etc.
  • a washing machine or other cleaning appliance such as a dishwasher, carpet cleaner, mop, electric soap dispenser, etc.
  • Such cartridges can be especially useful in auto-dosing machines, where they can simply be inserted, and the identification device 120 (through the transmitter-receiver pairs 110) can detect the presence of a cartridge with cleaning product, identify the contents by detecting the coding information (number of protrusions and configuration), and auto-dose according to the contents.
  • protrusions 102 and transmitter-receiver pairs 110 which are contact-less provides for a simple, yet quick and effective way of identifying a particular cartridge and the contents therein.
  • prior art identification systems used metallic contacts. Such materials can result in corrosion when using aqueous solutions.
  • contactless detection e.g., infrared, visible light, ultraviolet
  • the protrusions 102 and transmitter-receiver pairs 110 never have to come into contact, which can improve the lifespan, make the parts easier to manufacture (e.g., do not need to meet the tight tolerance levels for connecting parts), and can avoid corrosion issues related with past systems that used metallic parts with contacting electrodes. Additionally not using metallic parts can result in cost-savings in materials.
  • FIG. 5 shows a dispensing unit 202 of the cleaning appliance 200.
  • the dispensing unit 202 has two cartridge inserts 204 configured to accept a cartridge.
  • Each of the cartridge inserts 204 has the identification device 120.
  • Cartridges containing different cleaning products are placed into the cartridge inserts 204 and coupled to the respective identification device 120.
  • one cartridge can have cleaning detergent as its contents and the other cartridge can have fabric softener for use with a washing machine.
  • the liquid conduit 24 can be formed through the connected elements such that the cleaning detergent can be discharged from the cartridge 10’ into the cleaning appliance 200.
  • the identification device 102 through the transmitter-receiver pairs 110 (communicating with the processor) recognizes that the cartridge contains detergent, and will dose accordingly without requiring any manual input by the consumer telling the system what is in the cartridge. Similarly, with the cartridge containing fabric softener, the cartridge is inserted and the identification device (communicating with the processor) identifies the cartridge as containing fabric softener. It can then use that information to dose accordingly without the user having to manually input the contents.
  • such a system can be especially useful when many types of cleaning products are used in a cleaning appliance or system.
  • the user simply has to insert the cartridge containing the agent, and the identification device will identify and correctly dose the contents by recognizing the number and configuration of protrusions that relate to a specific cartridge and/or cleaning product. While two cartridges and identification devices are shown, more or fewer could be used in specific systems.
  • the system could include any number from 1 transmitter-receiver pair to 10 or more. The more transmitterreceiver pairs present, the more options for identifying different cartridges/contents of cartridges.
  • the protrusions 102 are shown as extending from cap 50’ in the examples and drawings, they could extend directly from the outside of the cartridge itself instead of or in addition to protrusions on the cap. Additionally, the cartridge shown in Figs. 1A- 3C and identification system in Figs. 4A-5 could be used together, or could be used with separate cartridges/systems.
