Description

SUBSTANCE: invention relates to devices for washing machines, in particular to clamping devices of a detergent dispenser in operation of washing machines.

All washing machines vibrate both during washing and spinning of the laundry, this is due to the uneven distribution of wet laundry in the drum, which during washing can take a "lump" to the perimeter of the drum rotation, forming a single lump of laundry.

The ARISTON automatic washing machine is known all over the world due to its quality, design and implementation of advanced technologies. Some car models are called "Hotpoint Ariston".

One can cite a published water-consuming household appliance, in particular a dishwasher or washing machine with a built-in valve (Patent RU No. 2382264, F16K 31/70, A47L 15/42 dated 20.02.2010). However, the known solution does not address the issue of preventing water leakage through the detergent dispenser (i.e. where the detergent is poured under water pressure, it dissolves).

An additional search among the solutions known in science and technology related to washing machines showed that the serial production of modern washing machines used models published on the Internet (Site): hitps: //Jandex.ru/search/, detergent dispenser, included in the kit in the form of a dosing tray, which is included in the inner cavity of the hopper. It depends on how tightly its body is made for pressing with the side walls (ends) when water enters the hopper of the metering tray. The Internet provides general information on the device of the ARISTON washing machine and other machines.

Known from the sources of the European patent description CN 108895194 (A) -2018-11-27, as well as CN 207093869 (u) -2018-03-13, according to the class F16K 17/00, F16K 27/00, F24H 9/00. They are looking at water leaks from devices. However, this is all about a water heater or the like, which is only applicable to the specific needs of the water container.

From this point of view, the Hotpoin ARISTON washing machine (see the device of the Hotpoint ARISTON washing machine - pictures, etc.) is closer to the one declared in technical essence and the achieved result, the chosen analogue (prototype), and more specifically (see. Internet: detergent dispenser, included in the kit in the form of a washing machine dispenser tray).

The locking device for the dispensing detergent (hereinafter the dispensing tray) is intended for the correct dosage of the detergent, inside which detergent or liquid is poured, then the device is tightly covered to the side walls of the hopper, into which water is supplied under pressure to dilute the detergent, then it enters the drum is also under pressure, while the water in the dispensing tray is extinguished to dilute the detergent due to the presence of a valve and the dilution of the powder in the so-called detergent dispenser device. The diluted mixture enters the rotating drum of the washing machine and wets the laundry under the shower.

It should also be noted that technical progress consisted primarily in the automation of individual elements of the washing process. It all started with the introduction of an automation system, first of the simplest type, and then electronic, based on microprocessors.

The model of the Hotpoint Ariston washing machine represents the following technical characteristics: Model ARSL - 100, dimensions: width - 59.5 cm; height - 85 cm, depth - 40 cm; loading 1-5 kg; hydraulic parameters: maximum pressure 1 MPa ( 10 bar), minimum pressure 0.05 MPa (0.5 bar), drum volume 40 l; spin speed up to 1000 rpm; control programs according to EN 60456 - program 7; temperature 60 ° C, load up to 5 kg.

The washing machine complies with the following: Directives of the European Economic Community: - 89/336 / EEC of 03.05.89 electromagnetic compatibility and subsequent modifications - 2002/966 / CE.

Nevertheless, all known solutions for washing machines, for example, "HRISTON", have a significant drawback for the following reasons:

- use of a detergent dispenser - (dispenser tray) is fixed from the outside to the side wall of the washing machine body, which then, turning on its vertical axis of rotation, enters (comes out) inward under the lid into contact towards the hopper (something can be compared to “ box with a sliding base "), which is freely pressed (according to the prototype) to the ends of the hopper body, closed from the top by a washing machine lid without a latch and without a seal, which means that when a loose (not strong) force is pressed by the hand on the body or when the machine itself vibrates when washing, it can move outward from the side walls (this case occurred in our example in practice, when a person went into another room, and the machine was in automatic operation, then a large water leak occurred with the formation of a puddle on the floor near the machine). In this case, water leakage occurs after filling in the powder and diluting it when covering;

- in case of water leakage, detergent is lost with a smell that is not pleasant for human health, i.e. there is no possibility of engaging (fixing) the protruding lateral end parts of the locking device for the dispensing detergent in the form of a dispensing tray, i.e. even from the top, the cover covering the whole set of the device as a whole cannot ensure the reliability of the streak. Thus, there is no rigid fixation - there is a weakening and loose closing of the locking device in the form of a distributing detergent upon contact with the hopper;

- there is no possibility of fixing the dispenser tray during operation (operation) of the washing machine during its long-term operation (use), and this creates great problems in maintenance in the temporary absence of a person, and requires improvement of this device in the practice of mass consumption of machines, in part during the period of strika laundry, especially in its excessive vibration (the possibility of insufficiently tight closure) during a rotating drum with a high rotation speed during washing and spinning the laundry.

The objective of the invention is to improve the locking device for the distributor of detergents (dispenser tray), which provides an increase in the reliability of fastening and the method of its use in the washing process.

The technical result consists in a method for fixing the detergent dispenser to the hopper body, covered from above by the lid of the washing machine as a whole, which does not allow spontaneous opening of the dispenser tray during prolonged washing and wringing out the laundry using a locking element for fixing in the groove of the end part of the side wall of the machine, and also the supply of a rubber seal with a clamp.

The specified technical result is achieved by the declared locking device for the detergent dispenser, including a dosing tray in the form of a detergent dispenser, a hopper built into the hopper when moving into it, a hose from the inlet valve is connected to the hopper, through which water is supplied to the compartments under pressure, then for sampling powder, according to the invention, the dosing tray is additionally equipped with a locking element in the form of a ferromagnetic metal, above which there is a rubber seal, under the lid, while relative to the end of the ferromagnetic metal, a permanent magnet is installed at the end of the side wall of the washing machine, fixing the dosing tray in the closed position after pouring detergent into it.

The hallmark is:

- a fixing element made of ferromagnetic metal, in contact with a permanent magnet, secures the dispenser tray for the duration of a long wash of laundry, and opens it at the end of washing the laundry.

In order to supplement the description that is given below and to facilitate a better understanding of the features of the invention, in accordance with the preferred example of its implementation, a set of drawings is attached as an integral part of said description, in which the following is presented in an explanatory and non-limiting quality:

in fig. 1 is a perspective perspective view of a locking device for a detergent dispenser, with the rear panel removed to show the interior of the washing machine more clearly; in fig. 2 shows a schematic view of a detergent dispenser (dispenser tray)) with a water supply valve, open; in fig. 3 shows a schematic view of the dispenser tray from the side wall in an open state.

The proposed invention, a locking device for a detergent dispenser of a washing machine, comprises a washing machine 1 with a control panel (not shown), includes from the side of the top cover and from the side of the rear panel (wall) of the controller body 2, a counterweight 3, a detergent dispenser in the form of a tray - dispenser 4 with latch 5 and key 6, water supply valve 7, hopper 8, hose 9, valve 10, level sensor 11, tank 12, pulley 13, belt 14, temperature relay sensor 15, electric heater 16, electric motor 17, drain hose 18, drain hose of level 19, condenser 20, electric pump 21, filter 22. In addition, the detergent dispenser 4 (dispensing tray) consists of a body with a latch-like locking device inside, and the end of the side wall of the washing machine 1 has an internal groove 23, in which the latch 5 is fixed.

The upper inner part of the end along the length of the dispensing tray has a seal 24 in the form of rubber for contact with the upper part of the groove end in the cover of the washing machine 1 to eliminate leakage when closing the dispensing tray 4 by pressing the latch 5 (according to the embodiment) with the key 6 to open the latch 5 in the groove 23.

According to the main variant of the claims, the end side wall of the lower part of the dosing tray 4 is made of ferromagnetic metal 25, a seal 24 in the form of rubber is also fixed on the upper end of the dosing tray, providing hermetically pressing (closing the dosing tray 4, and opposite the end side wall the lower part of the dispenser tray, a permanent magnet 26 is fixed on the side wall of the end of the washing machine body, fixing the ferromagnetic metal 25 with the dispensing tray 4 in a closed position after filling it with washing powder.

The technical characteristics of the Hotpoint ARISTON washing machine are described above.

The work with the locking device is as follows.

According to one of the embodiments, in order to bring the detergent dispenser 4 (dispenser tray) into operation, it is necessary to open it by pulling the plastic button 6 towards yourself, open the latch 5 (lock), which goes out from the groove 23. Before filling in the powder, check the installation of the valve 7 for supplying water under pressure to the compartments of the dosing tray 4. Next, the detergent (powder) for washing clothes is poured in before starting the machine. After that, the dispenser tray 4 is tightly closed and fixed by manual pressing against the lid with a groove (not shown) of the washing machine towards the hopper 8 due to the latch 5 with the key 6 into the groove 23 into the end of the side wall of the machine body. After reaching and confirming the click of the latch 5 that the fit occurred by pressing the button 6 on the body of the dispensing tray 4, it is checked that it has closed, the device is fixed and water leakage is impossible in any case, i.e. there is a tight locking of the dosing tray 4 towards the hopper 8.

According to the embodiment, the locking device ensures reliable fixation of the dispensing tray 4 (distributor washing device), but only by rubber sealing by applying smooth pressure by hand through the button 6. The opening of the dispensing tray 4 is released by pressing the button 6 with latch 5, disengaging groove 23 of the machine body and exit from the fixing state of the fastening, thus there is no accidental opening when the washing machine vibrates in operation (spinning) or under-pressing tightly, depending on the application of a person's hand when closing the dispenser tray 4. It is a click (sound) when the latch is closed 5 shows that the device is ready for washing machine operation, i.e. it can be turned on.

According to the proposed formula of the invention, when closing the dosing tray 4 with the washing powder filled in, a reliable attraction occurs and is fixed by a permanent magnet 26, which leads to a hermetic closure between the dosing tray 4 towards the hopper 8. The stage of washing the laundry begins when the washing machine is turned on, after finishing the process washing clothes, apply physical force of the hand, and by pressing the key 6 on the latch 5 leads to the opening of the dispenser tray 4, since the applied physical force of the hand will be greater than the holding force from the attraction of the magnet 26 to the metal ferromagnet 25.

Thus, in comparison with the known device of the design of the distributor of detergents in the form of a dispenser tray 4, the new improved locking device allows for tight fixation with high reliability, having a simple system of assemblies. The safety of the washing machine is increased and the introduction into production as an improvement in the mass design of the washing machine.
