Description

HOUSEHOLD MACHINE IN WHICH WATER CIRCULATES

The subject of the invention

The subject of the invention is a household machine in which water circulates, such as a washing machine or a dishwasher, with a dosing container for a manual detergent dosing system and a built-in system for automatic detergent dosing.

Technical problem

The technical problem is to design such a household machine in which water circulates, such as a washing machine or dishwasher, with a system for manual and automatic dosing of detergent, which will allow the reception of detergent and / or care product in one place, regardless of the detergent dosing method. and types of detergent, the dosing of detergent for the user must be easy, and at the same time the manufacture of such a household machine must be economically justified.

State of the art

Today, in household appliances in which water circulates, especially washing machines for washing and caring for laundry, systems that allow automatic dosing of detergent are often used. Automatic dosing should bring the optimal amount of detergent into the laundry washing and / or care process according to parameters such as the type of detergent, the amount and soiling of the laundry, the water hardness and the selected washing program. This dosing method is therefore more environmentally friendly as a smaller amount of detergent is used for washing on average. Despite dosing automation, it is still used and requires the possibility of manual dosing of detergent in the classic way via a dosing container, as many users still want to have control over the operation of the machine or have specific needs, desires and habits for washing and grooming.

In the case of conventional, manual dosing of the detergent, it is introduced into the washing machine via a dosing container comprising a housing fixed in the washing machine, a pull-out drawer arranged in the housing and a cover-rinsing part covering the drawer together with the housing. The dosing container is usually located on the front of the machine so that it is easily accessible to the user. The pull-out drawer can be divided into several compartments, which are intended e.g. for receiving detergent for main washing, pre-washing and laundry care. . The drawer, together with the compartments, is designed so that it can accept detergent in powder or liquid form. Such types of dosing containers are generally known. The detergent is manually poured / poured into the individual compartment depending on the selected laundry treatment program. The dosing of an individual detergent is left to the user, who fills the dosing drawer with detergent before each wash.

In newer washing machines, the dosing of the detergent is carried out automatically by means of t. i. automatic dosing system. An automatic dosing system uses a liquid detergent contained in at least one special container. The container has such a volume that it can accommodate a larger amount of detergent for multiple washes. The container is installed inside or outside the washing machine so that the user can fill it or replace it with a new, full container. In the case where the container is installed in a machine, its shape is specified and only the prescribed shape can be used. Whether the container is being filled or replaced, it is important that it is installed in a place that is accessible to the user and easy to manipulate.

EP 2478145 A1 shows an automatic dosing system which has only a dosing container for receiving two types of liquid detergent, which are dispensed into the tub of the washing machine via an automatic dosing system. The user does not have the option to use the manual detergent dosing method nor does he have the option to use powder detergent.

Washing machines with an automatic dosing system are known, which have a dosing container for manual dosing of detergent and an additional dosing container in which the liquid detergent is stored in two containers of a certain shape and size. When the containers are empty, they must be replaced or filled with new liquid. The containers are located in the front, lower part of the machine. Because the containers must be large enough to accommodate a sufficient amount of detergent for multiple automatic dosing, they can only be installed right next to the bottom of the machine, otherwise there is no room for them elsewhere due to space constraints in the machine. The user accesses the containers through the added door located on the front of the washing machine. If the user wants to replace the container or refill the amount of liquid detergent in it, he must bend almost to the floor. In addition, the two containers are covered with swing doors, the installation of which means additional technological operation. Because the front of the washing machine has an additional cut-out, the external appearance of the washing machine is aesthetically inconsistent, especially compared to a tumble dryer. Nowadays, there is a tendency for the coordinated appearance of both machines, because in the apartment they often stand next to each other.

A solution is known from EP 2053154 A1, in which the automatic dosing of liquid detergent is carried out by inserting an additional container with liquid detergent into one of the compartments, if necessary, which then discharges a certain amount of liquid detergent into the dosing drawer via a special trigger system. and on to the machine tub. The disadvantage of such an embodiment is that by inserting an additional container into the dosing drawer, one compartment of the dosing drawer is lost. The amount of detergent is also very limited.

EP2340326 A1 describes a dosing container with two compartments, the first compartment comprising one compartment for receiving powder detergent for manual dosing, the second compartment comprising two compartments each receiving its own type of liquid detergent for the automatic dosing system. The dosing container is preferably intended for receiving liquid detergent in an automatic dosing system. If the user wants to wash by hand dosing, he can use only one type of detergent in powder form, he cannot perform the washing mode with prewash and / or fabric softening, nor can he use liquid detergents, because he has only one compartment. Due to the limited space available in the dosing drawer, the compartments for receiving liquid detergent for automatic dosing are relatively small and need to be filled frequently.

Solution to a technical problem

The technical problem is solved by a household machine in which water circulates according to the invention as defined in the first independent patent claim. Additional features are defined in the dependent claims.

According to the invention, a household machine in which water circulates has a system for automatic dosing of detergent with a dosing container for receiving detergent in manual dosing, which dosing container comprises a housing, a pull-out drawer arranged in the housing and a cover part covering the drawer and housing. the pull-out drawer having more than one detergent receiving compartment in powder and / or liquid form and comprising on the outside of its bottom a shaped chamber and at least one compartment, preferably two compartments, which are fluidly connected to the household automatic dosing system via the designed chamber. machine.

A fluid connection in the form of a tube is established from the container to the dosing container or to the dosing drawer.

A household machine in which water circulates, such as a washing machine or dishwasher, has a pull-out dosing drawer having at least one additional compartment for liquid detergent and / or care product having an outlet in its bottom and on the outside of its bottom , at least one shaped channel in the form of a channel running along the day, which forms a fluid connection between the additional chamber and the automatic dosing system arranged in the household machine.

In the pull-out drawer, there are two additional compartments, which are arranged inside the pull-out drawer along its front side, closed with a swing lid and have an outlet opening in their bottom. Each additional compartment is in fluid connection with one channel.

Each channel has a brightness that is closer to the front of the drawer and coincides with each drain opening of the additional compartment, and a light that is distant from the front of the drawer and ends with the spout.

The bottom of the pull-out drawer is tilted down towards the inside of the machine.

The dosing tank housing has a spout at the front end with a pipe fitting for receiving the filling pipe, which connects the dosing tank housing and the liquid detergent container of the automatic dosing system.

Household machines comprise a fluid connection of the liquid detergent between the dosing container and its pull-out drawer and the liquid detergent container of the automatic dosing system.

According to the invention, a household machine in which water circulates enables the dosing of the detergent in one place, regardless of the choice of dosing, ie manual or automatic dosing. This dosing method is more user-friendly and easier. The user enters all the necessary detergents into the machine in the standard place of the machine and does not require its removal. Despite the fact that the household machine is equipped with an automatic dosing system, the user can also use a manual detergent dosing system without restrictions for all types of washing procedures and with various detergents and / or care products in powder and / or liquid form. Thus, the consumer has the option of performing a variety of laundry washing / care procedures, which are easily enabled by manual dosing of the detergent or the use of an automatic dosing procedure.

The dosing container and its pull-out drawer in the case of using an automatic dosing system are not formed as a detergent container but only as an integral part of the fluid connection formed between the dosing container and the respective detergent container in the automatic dosing system. The household appliance according to the invention contains at least one container of detergent for automatic dosing, preferably two, and could contain more. The containers for the automatic dosing system for the liquid detergent can be arranged anywhere inside the household machine, preferably where there is space, and can be of any shape adapted to the space available. Because the user fills them indirectly via the dosing container, direct access to the containers from the outside is not required. This also means that there are no additional cut-outs in the outer front of the machine, which would require additional technological operations and could negatively affect the aesthetics of the machine.

The household machine according to the invention simplifies the manufacturing process. The dosing container, which is installed in the household machine according to the invention, enables uniform production regardless of the type of dosing system. In the case of using only a manual detergent dosing system, it is possible to make a dosing container for only manual detergent dosing with practically the same procedure and minimal tool additions, which further economically justifies the production of a household machine according to the invention.

Because the liquid detergent containers of the automatic dosing system are built into the machine itself and are filled via the dosing container from the front, the household machine can stand directly next to the wall and does not require additional handling space.

The technical solution of the household machine according to the invention will be shown in more detail with an exemplary example and sketches showing

Inside the housing 2 of the washing machine is arranged a system for automatic dosing of detergent 26, which is not the subject of the present invention.

The dosing container 8 comprises a dosing container housing 9 fixedly and arbitrarily attached to the washing machine housing 2, a pull-out drawer 10 arranged in the housing 9, having more than one detergent receiving compartment in powder and / or liquid form, and a flushing lid 11 covering a pull-out drawer 10 and a dosing container housing 9.

The pull-out drawer 10 is substantially box-shaped and has a bottom 10.1 surrounded by two sides 10.2, 10.3 and a front 10.4, which is essentially part of the front of the washing machine 1. At the rear, the pull-out drawer 10 is open so that the washable / the care agent flows together with the water from the drawer into the housing 9 of the dosing container and further into the tub 3 of the washing machine 1. The pull-out drawer 10 comprises more than one inside, preferably three compartments 12, 13, 14 for receiving the detergent and / or care manual dosing. The compartments 12, 13, 14 can be arranged in parallel with each other and can extend along the length of the pull-out drawer 10. The size of each compartment 12, 13, 14 is arbitrary and depends on the type of detergent / care agent it receives. In the pull-out drawer 10, in addition to the compartments 12, 13, 14, there is at least one, preferably two additional compartments 15, 16 for liquid washing and / or care agent for the automatic dosing system. The automatic dosing compartments 15, 16 are located at the front 10.4 of the pull-out drawer 10. Each additional compartment 15, 16 has an outlet opening 15.2, 16.2 in its bottom and is closed by a swing cover 15.1, 16.1. The number of additional compartments is equal to the number of containers for liquid detergent in the automatic dosing system.

At least one chamber, preferably two channel-shaped chambers 17, 18, is formed on the outside of the bottom 10.1 of the pull-out drawer 10 along its entire length. The respective channel 17, 18 runs along the bottom of the pull-out drawer 10 so that the respective channel brightness closer to the front side 10.4 of the drawer coincides with the respective drain opening 15.2, 16.2 of the additional compartment, each channel brightness distant from the front side 10.4 of the drawer, ends with the spout 17.1, 18.1.

Due to the better leakage of detergent from the pull-out drawer, its bottom 10.1 can be inclined downwards towards the inside of the machine so that the bottom end closer to the front 6 of the machine 1 is higher, ie closer to the top of the machine, than the other end of the drawer 10. is facing away from the front 6 of the machine and facing the inside of the machine. This slope is also followed by channels 17, 18.

The housing 9 of the dosing container, which is attached to the housing 2 of the washing machine, essentially surrounds the pull-out drawer 10. The housing 9 is open at the front end at the front of the machine to allow pull-out drawer 10. The housing 9 of the dosing container has a spout at the front end a mouth 20, 21 with a respective tube fitting for receiving the respective filling tube 22, 23, which connects the housing 9 of the dosing container and the respective container 24, 25 for the liquid detergent of the automatic dosing system. Container

24, 25 are arranged inside the washing machine, preferably in the lower part of the machine between the tub 3 and the housing 2 of the machine. The volume of the individual container 24, 25 is arbitrary, depends mainly on the available space in the machine and is at least such that its contents are sufficient for several washes. A fluid connection is created between the dosing container 8 and its pull-out drawer 10 and the containers 24, 25 and further with an automatic dosing system which is not the subject of the invention.

In the case of a household appliance in which water is circulating, according to the invention, such as a washing machine or dishwasher, the user is free to choose between a manual detergent dosing system or an automatic detergent dosing system. The selection of the system is confirmed via the control part of the machine. If using a manual dosing system, it pulls out the pull-out drawer 10 and the detergent and / or care agent in powder and / or liquid form is poured / poured into the individual compartment 12, 13, 14 depending on the choice of washing process.

When choosing an automatic dosing system, containers 24, 25 or at least one of them must contain a sufficient amount of detergent. Otherwise, the user receives information via the control unit that the containers need to be filled 24,

25. At that time, the user pulls out the pull-out drawer 10 to its extreme position, where the respective spout 17.1, 18.1 of the respective channel 17, 18 is arranged above the respective spout 20, 21 of the housing 9 of the dosing container. The spout 20, 21 are connected via filling nozzles to the filling hoses 22, 23, which lead the liquid detergent to the respective container 24, 25. When the container is filled to a predetermined level, the user receives a notification via the control unit. In case of overfilling the container, the liquid detergent from the additional compartment or filling tube flows along the bottom of the housing 9 of the dosing container, through the spout 9.1 and further into the tub 3. Limiting the extreme pull-out position of the pull-out drawer 10 is possible in different ways. - magnetic sensor. In this case, one part of the sensor system can be mounted on a fixed part, e.g. on the housing of the dosing container or part of the housing of the apparatus, and the other part on the movable part, ie the pull-out drawer.

A household appliance in which water circulates according to the invention, such as a washing machine or dishwasher, also enables the use of an external container for liquid detergent in the case of an automatic dosing system. In this case, on the rear side of the pull-out drawer 10, suitable connecting elements are arranged through which the liquid detergent enters the pull-out drawer, further into the housing 9 of the dosing container and into the tub 3.

It is to be understood that one skilled in the art can make other embodiments without circumventing the spirit of the invention.
