Mixing system set and method for producing a cleaning agent

The invention relates to a mixing system set and a method for producing a

In particular, the invention relates to a mixing system set suitable for the production of several cleaning agents and a method for

suitable for the production of various cleaning agents.

There are a variety of different cleaning products and types such as glass cleaner,

Sanitary cleaners, dishwashing liquids, all-purpose cleaners, floor cleaners, etc., which are available for purchase as products. Users are often unsure which product is the right one for the respective application and often feel overwhelmed when making a choice. At the same time, the

Application concentration and type of application are often complicated and unclear for the user, resulting in great uncertainty among users.

Most of the products available for purchase are not highly concentrated and consist of 80 to 98% water and are packaged in plastic bottles. These products contain

Application solution therefore only has a low active content, which leads to a lot of water being wasted and an unfavourable ratio of packaging to cleaning

The plastic bottles are often used only once or rarely by the user and then disposed of after a while. However, they are often only sold in larger

packaging. This leads to the user unnecessarily disposing of chemicals and plastic.

With a mixing system set consisting of several components, many types of cleaning agents can be mixed with water. However, not all components can be easily mixed and can form lumps. The formation of such lumps must be prevented in order to ensure that such a mixing system set is easy to handle.

The invention therefore addresses the problem of producing a large number of cleaning agents with a

To reduce plastic waste and product diversity as well as to provide cleaning performance adapted to user needs.

According to the invention, this problem is solved by a mixing system set with the features of the

Patent claim 1 and a method with the features of patent claim 9 are solved.

Advantageous embodiments and further developments of the invention emerge from the following subclaims.

The advantages that can be achieved with the invention are that with as few

Components several, a large number or at least ten of the most commonly used

Cleaning agents can be easily produced by the user on site. Demand-based production of cleaning agents and use is provided. s This can reduce plastic waste through reusable containers and reduce product diversity by simplifying the range and creating

Transparency can be achieved.

The user can produce the amount of cleaning agent they want, depending on their individual needs, for example, depending on the size and furnishings of their apartment, hobbies, car, etc. There is also no need to transport water. There is also no need for preservatives, as the cleaning agents can be freshly produced. They do not need to be preserved for months of storage. There is also no need for stabilizers, as the cleaning agents can be used straight away.

The use of stabilizers, which are normally intended to keep the components of the cleaning agents homogeneous in solution, is not necessary.

The invention relates to a mixing system set for producing a plurality of cleaning agents, comprising - a plurality of components stored separately from one another, which comprise a surfactant component, a solvent component, an acidic component, an alkaline component, and - a mixing device which is designed and arranged to mix the plurality of

Components depending on predetermined cleaning agent

proportions for the production of the respective cleaning agent, wherein the mixing device is designed to first mix the solvent

Component and surfactant component to be dosed and premixed and then the acidic component and/or alkaline component to be dosed and mixed with the premix of solvent component and surfactant component if the surfactant component is used to produce one of the cleaning agents.

With the mixing system set of at least four components and if necessary water for

Most cleaning agents can be made by dilution. The water is preferably available to the user on site in the home or business, but it can also be part of the mixing system set. The cleaning agents are preferably so-called household cleaners, even if they can be used in the commercial sector. The four essential components are the surfactant component, the solvent component, the acidic component and the alkaline component. The mixing system set has the four essential components separately from one another in containers such as cartridges or containers.

Each of the four components is preferably liquid and preferably contains water.

Each of the components is a concentrate. Therefore, only the components in highly concentrated form need to be transported by the user from the place of purchase to the desired place of application. This saves packaging waste.

Because the mixing device first doses the surfactant component and the solvent component together and then mixes the resulting premix with water, the 190 acidic component and/or alkaline component, the surfactant component is prevented from forming gel lumps when mixed with water, which practically do not dissolve or only dissolve again very slowly. This also prevents the mixing device from clogging. In addition, using the mixing device ensures safe application through automatic mixing. This means that the user does not come into contact with the chemical compounds of the components.

The predetermined proportions of the components preferably depend on the type of cleaning agent to be produced that the user wants. Depending on the type of cleaning agent to be produced, the proportions of the components can also be zero. This means that not all cleaning agents to be produced have to contain all four of the above components.

Preferably, the mixing device is designed to dose the surfactant component only in combination with the solvent component. This means that every cleaning agent produced contains the surfactant component as well as the solvent component. The dosage or use of the solvent component is preferably independent of the use of the surfactant component.

Component independent, so that a manufactured cleaning agent contains the solvent

component but may be surfactant component-free.

In a preferred embodiment, a mixing ratio of the surfactant component to the solvent component is from 10 to 1 to 1 to 10, preferably 5 to 1 to 1 to 5, more preferably 5 to 1 to 1 to 1. This further achieves a good cleaning performance of the cleaning agent produced without gel clump formation.

Preferably, the mixing device has a mixing section, wherein each of the plurality of

Components are assigned a dosing point on the mixing section and a pump for dosing the respective component. The mixing device preferably has a

Control device which is designed to control the respective components

pumps at a predetermined time. This provides an advantageous

Mixing order of the components is ensured.

In a preferred embodiment, the solvent component associated with

Dosing point before the dosing point assigned to the surfactant component on the

Mixing section. The control device is preferably designed and constructed to

Solvent component is to be dosed in a period that begins at a point in time before the dosing of the surfactant component and at a further point in time after

Ending the dosing of the surfactant component ends. This is achieved by controlling the pump assigned to the respective component. This ensures that

The surfactant component and the solvent component are dosed at the same time. This prevents the surfactant component from simply mixing with water and forming gel clumps.

In a preferred embodiment, the control device is set up and designed to start dosing water into the mixing section by controlling its associated pumps at a time that is before the dosing of the solvent component and the surfactant component. The dosing point assigned to the water is preferably behind the dosing point assigned to the solvent component and behind the surfactant component.

Dosing point on the mixing section assigned to the component. This prevents the surfactant component from forming gel clumps when mixed with water.

Preferably, the dosing point associated with the acidic component and/or the dosing point associated with the alkaline component is located behind the dosing point associated with the water.

Dosing point is arranged on the mixing section. This means that the mixture of the surfactant

Component and the solvent component are already pre-diluted with water when the acidic and/or alkaline component(s) are dosed into the mixing section.

In a preferred embodiment, the conveying capacities and/or the

The pump timing is the same. Alternatively, the flow rates and/or the

Timing of the pumps varies. The settings of the delivery rates and/or

The timing of the pumps is preferably selected in such a way that the mixing ratio of the components to one another predetermined for the respective cleaning agent to be produced is ensured.

Preferably, the cleaning agent produced is a grill cleaner, oven cleaner, kitchen and/or

Power cleaner, floor cleaner, all-purpose cleaner, hand dishwashing liquid, glass cleaner, toilet cleaner,

Bathroom cleaner or descaler.

Preferably, the mixing system set also has two empty containers if it contains the

mixing device. One container is preferably suitable for filling with water, while the other container is preferably suitable for accommodating the cleaning agent produced using the four essential and optional components.

The components stored separately from one another are preferably housed in containers such as cartridges or containers in the mixing system set. The mixing device is preferably designed and configured to automatically fill the cleaning agent produced after mixing the intended components into the intended container.

In a preferred embodiment, the surfactant component comprises a mixture of nonionic and anionic surfactants. Optionally, the surfactant component further contains amphoteric surfactants and biosurfactants.
