Description

Technical field

The invention relates to a water-consuming household appliance, in particular to a laundry treating apparatus for washing and / or drying laundry, with a treatment chamber and a channel system through which a liquid stream can be directed into the treatment chamber, at least a portion the channel system is made in the form of a siphon, and a control valve and a control unit are provided, the control unit activating at least one control valve to control the fluid flow through the channel system, and redusmotreno emptying device, which serves for the partial emptying siphon. In particular, the invention relates to the field of washing machines and washer-dryers.

State of the art

DE 102009029523 A1 describes a similar water-consuming household appliance with a hydraulic shutter. In this household appliance, a processing chamber is provided comprising a supply element. In addition, a hydraulic shutter is connected to a supply element of the processing chamber, wherein the hydraulic shutter comprises a vacuum suction. The function of the vacuum suction device is to maintain a certain level in the hydraulic shutter. This function follows from the fact that the vacuum suction device serves as an evacuation device designed to remove excess liquid from the siphon and partially empty the siphon, in particular, to a level determined for the corresponding inlet of the vacuum suction device. As a result, firstly, sufficient water can remain in the hydraulic shutter to create a reliable steam shutter for the washing and / or drying steps. Secondly, unwanted water flow from the hydraulic shutter is prevented. In particular, a situation is prevented in which, for example, when opening the door of a household appliance, water would flow out under pressure equalization from the hydraulic shutter and enter the processing chamber. Thus, the hydraulic shutter forms a reliable steam barrier, while at the same time undesirable penetration of water from the steam barrier into the treatment chamber is eliminated.

In water-consuming household appliances, starting with a known size of the treatment chamber, it is desirable and perhaps even legally prescribed to provide, in addition to access through a door or similar access, another connection to the environment, providing breathing air in and out to protect living things falling into the processing chamber when the appliance is not working. Such an additional connection should be closed during operation of the household appliance, when it is necessary to exclude the release of gases and, possibly, liquids from the treatment chamber into the environment. To do this, it is necessary to occupy part of the already limited installation space, and the necessary components for this increase production costs.

Disclosure of invention

The objective of the invention is the development of a water-consuming household appliance, improved in terms of the design of the node, providing breathing in a closed appliance or ventilation / purge.

The problem is solved by a water-consuming household appliance, in particular, a laundry treating apparatus for washing and / or drying clothes, with the features of an independent claim. Preferred features and measures disclosed in the dependent claims, in the following description or in the accompanying figures, allow to realize advantageous embodiments of a water-consuming household appliance described by the invention.

Thus, the problem is solved by a water-consuming household appliance, in particular, a laundry treating apparatus for washing and / or drying the laundry, with a treatment chamber and a channel system through which a fluid flow can be directed to the treatment chamber, at least a part the channel system is made in the form of a siphon, and a control valve and control unit are provided, the control unit being configured to activate at least one control valve to control the fluid flow through the system Me channels, and provides a device for emptying, made with the possibility of partial emptying of the siphon. In addition, the control unit is configured to activate the shut-off valve in the locking mode so that the siphon is partially filled with a liquid flow to a level at which the siphon does not allow gas to pass through. In addition, the emptying device is configured to at least maximize the emptying of the siphon, and the control unit is finally configured to activate the dispensing valve and the emptying device in unlocking mode so that liquid is drained from the siphon to the point at which the siphon open for gas transmission.

A further preferred embodiment of the invention is characterized in that the emptying device is a vacuum suction device configured to at least emptying the siphon as much as possible, while the control unit is configured to activate the control valve in unlocking mode so that a flow of liquid through the rising section is ensured. and through the descending portion of the vacuum suction.

Within this embodiment, the emptying device works completely passively, since it is activated only by appropriately filling the siphon. Therefore, an embodiment in which a vacuum suction device is provided is advantageous. The combination of a vacuum aspirator and a siphon allows you to implement a purely hydraulic principle of operation, ensuring reliable operation throughout the life of a household appliance. In this case, a control valve can be used instead of an already provided shut-off valve or similar device, which allows optimizing the number of necessary components and the corresponding need for the installation space.

Also advantageous is the option in which the control unit is configured to activate a shut-off valve in unlocking mode so that a flow of liquid is provided through the rising portion and through the lowering portion of the vacuum suction. In the unlocking mode, for example, an increased amount of pure water or a mixture of pure water with a detergent may be directed to the treatment chamber. If the supply is interrupted, the siphon is emptied through the vacuum suction. As a result, it becomes possible for gas to pass through a siphon, in particular, air exchange through a siphon. Of course, if the siphon is closed, because, for example, the processing program step is being carried out, the control unit switches the shut-off valve, respectively, into the locking mode. The control unit is preferably configured to activate the shut-off valve in the locking mode so that the rising portion of the vacuum suction unit is partially filled with liquid through the fluid flow, while the descending portion of the vacuum suction unit remains free. As a result, the vacuum aspirator is partially filled with liquid to such an extent that it allows the formation of a gas-tight shutter and to prevent the passage of gas. Thus, the gases generated in the processing chamber, in particular, ozone or other gas used to improve the processing result, cannot enter the environment.

Preferably, the vacuum suction device is formed by a vacuum suction pipe, the siphon has an outlet that is located at least near the deepest point of the siphon, and the vacuum suction pipe enters one side of the siphon outlet. In addition, the other side of the vacuum suction pipe may enter directly into the processing chamber. As a result, in particular, the large cross-section of the siphon allows for sufficient air exchange with the siphon open. Then the siphon is reliably emptied through the vacuum suction pipe in accordance with the unlocking mode.

In this case, it is preferable that at least one more vacuum suction pipe is provided, the siphon contains at least one more outlet, which is located at least near the deepest point of the siphon, and an additional vacuum suction pipe enters one side into the optional siphon outlet. This increases reliability, as the emptying of the siphon is guaranteed even in the event of clogging or contamination of one of the channel systems.

Also preferred is a variant in which the vacuum suction device is made in the form of a system of channels. This can be realized by suitable execution of the channel system. For example, the cross-section in places can be reduced cross-section to create the effect of a vacuum suction. In this embodiment, it is possible to further reduce the number of necessary components, and thereby further reduce installation costs and space requirements.

A further alternative preferred embodiment of the invention is characterized in that the emptying device is a pump, the treatment chamber comprises an outlet connected by a drain channel to the pump, the channel system comprises an inlet pipe that enters the drain channel between the outlet and the pump, and the siphon is partially formed by the inlet pipe and partially drainage channel.

In this embodiment, the supply pipe for the treatment fluid is connected to a drain device, wherein the supply of the treatment fluid to the solution tank is through its outlet. In this embodiment, a siphon, periodically blocking the passage of gases and passing gases, is formed as if by itself. At the same time, a pump is used as an emptying device, which is already necessary for pumping the processing fluid from the solution tank. Such an emptying device is not passive, since for operation it must be activated by the control unit. In this case, however, the complexity of the household appliance does not increase, since this device is already one of the necessary components.

An embodiment is also preferred in which at least one sensor is provided in the channel system for determining the partial filling of the siphon. As a result, it is possible to reliably determine the moment at which the siphon blocks the passage of gases and, thus, prevents the possible release of possibly toxic gases, for example, ozone. In addition, in this case, a signal can be sent to the control unit, initiating an interruption of the fluid flow through the control valve in the locking mode.

A variant is also possible in which a flow meter is provided, configured to determine the amount of liquid required to partially fill the siphon. Moreover, such a flow meter may be necessary to perform other functions of a water-consuming household appliance, that is, such an embodiment does not increase the cost.

Brief Description of the Drawings

Preferred embodiments of the invention are explained in detail in the following description on the basis of the attached figures, in which the elements corresponding to each other have the same designations. The figures depict:

Figure 1: fragmentary schematic section of a water-consuming household appliance according to the first embodiment.

Figure 2: fragmentary schematic section of a water-consuming household appliance according to the second embodiment.

The implementation of the invention

The figure 1 presents a fragmentary schematic section of a water-consuming household appliance 1 according to the first embodiment. The household appliance 1 can be made, in particular, in the form of a device for processing linen and serve for washing and / or drying the laundry. In particular, the household appliance 1 can be made in the form of a washing machine or a washer-dryer. Of course, the household appliance 1 described by the invention can be used for other applications, in particular, it can be made in the form of a dishwasher.

The household appliance 1 comprises a processing chamber 2 surrounded by a tank 3. The tank 3 can be made, for example, in the form of a solution tank 3. Inside the solution tank 3, for example, there may be a drum for laundry or a similar element serving for laying the laundry.

The household appliance 1 contains a system of 4 channels through which it is possible to direct the liquid into the chamber 2 for processing. For example, through a system of 4 channels, clean water or a mixture of pure water and a detergent can be sent to chamber 2 for treatment. Moreover, the concept of "liquid" should be understood in a general sense. For example, the powder detergent can be washed off with clean water in the treatment chamber 2, and the complete dissolution of the powder detergent can only occur in the treatment chamber 2.

The supply of clean water is carried out through the pipe 5 of pure water. In this embodiment, clean water 5 first flows through the clean water pipe 6 to the flow meter 7. After the flow meter 7, clear water, overcoming the free air gap 8, enters the wash tray 9. This allows the detergent to be washed off, which may be in the wash tray 9 or in the compartment of the washable tray 9, through a system of 4 channels into the chamber 2 for processing. In this case, the fluid flow is created using a system of 4 channels.

The flow meter 7 is connected by a signal wire 10 to the control unit 11. The flow meter 7 determines the amount of fluid directed in the form of a fluid flow into a system of 4 channels. The found amount of liquid can then be analyzed by the control unit 11. The control unit 11 is connected by a control wire 12 to a control valve 13 installed in the clean water pipe 6. In this embodiment, the control valve 13 is designed as a control valve 13 with a butterfly valve. However, the control valve 13 might not have a throttle. Activation of the control valve 13 in normal operation allows you to open the supply of clean water at the beginning of the program and to block and reopen it in accordance with the individual stages of the program. For this, the control unit 11 can activate the control valve 13 in the usual way.

The system of 4 channels contains a siphon 15. In this case, part of the system of 4 channels is made in the form of a siphon 15. The system of 4 channels can be made of rigid plastic. For example, to form a system of 4 channels with a siphon 15, two pressure-molded parts can be welded together. Of course, the siphon 15 can also be formed by a flexible hose, bent accordingly. In this embodiment, the siphon 15 is U-shaped.

The siphon 15 has several levels: maximum level 16, middle level 17 and minimum level 18. Siphon 15 has the deepest point 19. The minimum level 18 is at least near the deepest point 19 of the siphon 15. The siphon 15 contains an outlet 20 through which the end 21 of the vacuum suction device 22 enters the siphon 15. In this embodiment, the vacuum suction device 22 is formed by a vacuum suction pipe 22. The vacuum suction device 22 comprises a rising section 23 and a lowering section 24. In this case and the side of the vacuum aspirator 22 enters siphon 15 at the minimum level 18. In addition, the other end 25 of vacuum aspirator 22 enters the chamber 2 for the treatment below the minimum level 18 of the siphon 15.

When clean water moves through a system of 4 channels, it is first directed along the descending section 26 of the siphon 15 to the deepest point 19, after which it rises along the rising section of the siphon 15 through the maximum level 16 to section 28 of the 4 channel system, and then descends along the downstream drain section 29 of the system 4 channels in the chamber 2 for processing. As pure water rises above the maximum level 16, the water level in the vacuum aspirator 22 also rises to its extreme upper point 30, as a result of which part of the clean water flows through the vacuum aspirator 22 into the treatment chamber 2.

If you stop supplying clean water, the liquid remaining in the siphon 15 will be continuously fed by a vacuum suction device 22 into the treatment chamber 2 until the minimum level is reached 18. After that, the siphon 15 will be at least as empty as possible, i.e. the connection between the processing chamber 2 and the free air gap 8 with the environment. Thus, in this embodiment, ventilation is carried out through the washable tray 9. In this case, for example, suitable openings can be provided in the washable tray 9.

However, such ventilation is generally inconvenient for a washing program. For example, water vapor, gas for processing, in particular ozone, foam generated during washing or another similar product can enter through an open siphon 15 into a washing tray 9 and, thus, into the environment. Therefore, a control unit 11 is provided that activates the shut-off valve 13 in the locking mode so that the liquid flow partially fills the siphon 15. At the same time, the amount of liquid filling the siphon 15 is filled into the siphon 15 to the average level 17. Moreover, the average level 17 is indicated for example, that is, there is a known tolerance field when a flow or quantity of water is supplied to partially fill the siphon. In particular, this amount is chosen sufficiently large, that is, the liquid level exceeds the minimum level 18 so that the siphon 15 is closed. On the other hand, the amount of liquid is not large enough to reach the maximum level 16. That is, the average level 17 is located at a sufficient distance from the maximum level 16. To achieve the maximum level 16, according to the law of communicating vessels, it would be necessary to fill the rising section 23 of the vacuum suction device 22 to extreme upper point 30, as a result of which the liquid would also fall into the descending section 24, which would lead to the inclusion of the suction effect on the vacuum suction when the clean water was further supplied Vatel 22.

Partial filling of the siphon 15 to an average level 17 can be realized by controlling the flow of water. In this case, the flow meter 7 determines the amount of liquid supplied to the siphon, and the control unit 11, in accordance with the found amount of water, timely shuts off the supply of clean water. Another option involves time control, according to which the control valve 13 is fully or partially opened, providing partial filling of the siphon 15 after a known time.

In addition, the filling level of the siphon 15 can be directly or indirectly determined using the sensor 35. In this embodiment, the sensor 35 is mounted on the rising section 23 of the vacuum suction device 22. As a result, the filling level of the rising section 27 of the siphon 15. can also be indirectly determined. that the average level 17 is reached, the control unit 11 can put the control valve 13 in the locked state based on the determination of this event. It is also possible that the sensor 35 is located in the siphon 15 in order to directly measure the liquid level in the siphon 15. In this case, preferably the sensor 35 is located on the rising portion 27 of the siphon 15.

In this embodiment, the air inlet and outlet can be realized through the handle of the flushing tray 9. Other variants are also possible. In this embodiment, the siphon 15 may have a large flow area, which allows for particularly good air exchange.

Thus, it is possible to purposefully partially fill and empty the siphon 15. During partial filling to an average level 17, the passage of gases is blocked. By supplying an additional amount of pure water filling the siphon to at least a maximum level of 16 and driving the vacuum suction device 22, the siphon 15 can be emptied deliberately. Thus, emptying can be realized by supplying a certain amount of water. This does not require a constant flow of water, that is, a large amount of water. Thus, at the end of the washing program, the siphon 15 can be emptied with a relatively small amount of water. The result is the possibility of breathing in a closed household appliance, since the empty siphon 15 is permeable to gases.

According to the design, water flooded to an average level of 17 remains in the siphon 15 arbitrarily long and without loss. Therefore, continuous filling is not required. That is, the individual switching states of the siphon 15 can be maintained for a long period of time. The siphon 15 can also be emptied by supplying a continuous flow of liquid, in which an arbitrary but sufficiently large amount of water is directed into the 4-channel system, the incoming volume flow exceeding the volume flow simultaneously drawn by the vacuum suction device 22. After the termination of this fluid flow, the vacuum suction device 22 at least empties the siphon 15 as much as possible.

In addition, figure 1 schematically shows an additional vacuum suction pipe 36 with a rising section 37 and a lowering section 38, forming an additional vacuum suction unit 36. As a result, two parallel vacuum suction pumps 22, 36 can be provided. This allows for a certain reservation, that is, even when clogging one of the vacuum aspirators 22, 36, uninterrupted operation is guaranteed. In addition, an additional sensor 40 may be provided that is installed in the region of the minimum level 18 in the siphon 15. The sensor 40 is connected to the control unit 11 of the signal wire 41. As a result, it is possible to reliably determine whether the siphon 15 is empty.

Using sensors 35, 40, the control unit 11 can also detect uninterrupted operation or a malfunction. This can be implemented with the possible consideration of the signal of the flow meter 7 and, possibly, additional signals. So, for example, based on the time required for the vacuum suction device 22 to lower the liquid level from the average level 17 to the minimum level 18, one can judge about the possibly increasing clogging of the vacuum suction device 22. For this, if necessary, you can also provide a sensor that detects the maximum level 16 . If the speed of the vacuum suction device 22 is no longer sufficient, the control unit 11 may output an error.

Since the middle level 17 has a large tolerance field, partial filling of the siphon 15 can be realized by time control without using a flow meter 7 or without using a signal from a flow meter 7. In particular, this allows water consuming household appliances 1 that are not equipped with a flow meter 7 or equipped with insufficiently accurate flowmeter 7.

If the siphon 15 has an undesirable siphoning effect, which can occur at certain cross-sections, then this action can be eliminated by placing a ventilation hole at the highest point of the siphon 15. In this case, the ventilation hole can be connected to the tank 3 using a suitable hose or similar element.

The figure 2 presents a fragmentary schematic section of a water-consuming household appliance according to the second embodiment. In this case, the vacuum suction device 22 is formed by a system of 4 channels. In this case, the rising section 23 of the siphon 15 corresponds to the rising section 27 of the vacuum suction unit 22. The falling section 24 of the vacuum suction unit 22 corresponds to the drain section 29. In addition, the highest point 30 of the vacuum suction unit 22 in this embodiment is located on the section 28 that connects the rising section 23 with a descending section 24 or a rising section 27 with a drain section 29. In this embodiment, the sensor 35 is located on the rising section 27 of the siphon 15. For clarity, the siphon 15 in figure 2 partially filled with liquid 42. In this case, the level 43 of the liquid 42 is approximately at the average level 17. As a result, the sensor 35 is activated, that is, the signal wire 34 sends to the control unit 11 a signal that the siphon 15 is closed for gas passage. Thereby, feedback is realized when a certain amount of liquid is supplied. In addition, with the help of the sensor 40, it is possible to determine whether the siphon 15 is emptied as much as possible, that is, to a minimum level 18. Thus, the control unit 11 can reliably monitor this state as well.

In this embodiment, the siphon 15 is emptied after the liquid has passed through both the siphon 15 and through a system of 4 channels. Since the system of 4 channels forms a vacuum suction device 22, then after the passage of the liquid, the siphon 15 is emptied as much as possible. If it is desirable to block the passage of gases, the amount of liquid 42 is sent to the siphon 15, as shown in figure 2.

The emptying of the siphon 15, filled with a known amount of liquid corresponding, for example, to level 43, can be realized by a predetermined supply of a relatively small amount of water. For this, as much liquid is supplied as is necessary to fill the siphon 15 to the highest point 30 and to pour the liquid through the descending section 24 of the vacuum suction device 22. As a result, the vacuum suction device 22 is activated, that is, the siphon 15 is emptied. Thus, the siphon 15 can be used in a known manner as a vacuum suction device 22. For this, it is possible to reduce the cross-section of the 4-channel system, at least in the region of the vacuum suction 22, in comparison with the rest of the 4-channel system. In this case, the channel cross section is chosen not too large, since otherwise it will be possible to reverse ventilation of the vacuum suction device 22 through the drain section 29, which will negate the siphon effect. However, even with a relatively large cross-section of the channel, it is possible to at least determine with the sensors 35, 40 whether the desired switching state has been reached.

Thus, the control unit 11 in the locking mode can activate the control valve 13 so that the fluid flow partially fills the siphon 15. In addition, the control unit 11 in the unlock mode can activate the control valve 13 so that the fluid flow passes through the rising section 23 and the lowering portion 24 of the vacuum suction device 22 and the siphon 15 is emptied. In this case, the unlocking mode can be initiated either by a continuous flow of liquid or by supplying a known amount of liquid STI to the level 42 shown in Figure 2, resulting in the runs vacuum aspirator 22.

In addition, the control unit 11 can carry out preventive or repair measures to prevent possible malfunctions from the very beginning. Such malfunctions can be, for example, a possible blockage of the vacuum suction device 22 by detergent residues, microorganisms or other obstacles. Malfunctions can be prevented by regular or targeted, in particular periodically initiated activation of the vacuum suction device 22.

The siphon 15 and the vacuum suction device 22 can also be implemented in another way, in the form of an integrated unit. For example, it can be concentric tubes. In addition, in order to reduce complexity, it is possible to partially or completely form the structure on specified parts, for example, a wash tray 9, a cuff, a wash hose or a solution tank 3. If necessary, this can be realized by appropriate distribution of system functions among various components.

The figure 3 presents a fragmentary schematic section of a water-consuming household appliance according to the third embodiment. At the same time, a pipeline 50 of the 4-channel system is provided, which is connected at the connection point 51 to the rising section 27 of the 4-channel system and to the section 52. The rising section 27 and section 52 are sections 27, 52 of the drain channel 53 connected to the tank 3 for solution. Moreover, the solution tank 3 comprises an outlet 54 on which a drain channel 53 is mounted. A drain channel 53 leads to a pump 55. A channel 56 is provided behind the pump 55, which can be connected, for example, to a drain 57 of a domestic sewer system.

Thus, in this embodiment, the rising section 27 of the siphon 15 is formed by section 27 of the drain channel 53. The procedure is as follows. To fill the solution tank 3 with a known amount of liquid, in particular a mixture of clean water and detergent, clean water is passed through the free air gap 8 and the wash tray 9. Then the mixture of pure water and detergent enters through the pipe 50 and the rising section 27 to the outlet 54 into the tank 3 for the solution. The amount of liquid directed to the solution tank 3 determines the maximum level or high level 16 ′ for the siphon 15. The connection point 51 is located between the outlet 54 and the pump 55, and the pump 55 is in the working position under the outlet 54. Between the outlet 54 and the place 51 the connection is the average level 17, and during the rising section 27, you can set a more or less large tolerance. Between the connection point 51 and the pump 55 there is a minimum level 18. At the same time, the pump 55 guarantees the pumping of liquid from the system of 4 channels to a minimum level of 18.

Based on the filling level set by a high level 16 ′, when the pump 55 is turned on, it is possible to reach the average level 17 and maintain it by turning off the pump 55. The deepest point of the siphon 19 is below the average level 17. Thus, a gas-tight shutter is formed. On the other hand, the average level 17 is below outlet 54, that is, there is no more liquid in the solution tank 3. As a result, for example, it is possible to supply an ozone-containing air stream in the laundry treatment chamber 2 without fear of ozone entering through the pipe 15 back into the washing tray 9.

At the end of the treatment program, the 4-channel system is emptied up to the minimum level 18. Since the lowest point 19 of the siphon 15 is above the minimum level 18, thereby guaranteeing the possibility of breathing in a closed appliance.

Pump 55 may be made depending on the application. Pump 55 may be an electric drive pump 55. The pump 55 can also be made in the form of a Venturi pump 55, which is indirectly controlled by the flow of merging water. A circulation system may also be implemented.

In the embodiment shown in FIG. 3, by supplying a known amount of liquid, it is possible to raise the level from a minimum level of 18 to an average level of 17 without fear of this relatively small amount of liquid entering the solution tank 3. The control unit 11 initiates the corresponding operation mode in accordance with the program execution algorithm. Thus, the pipe 50 in this embodiment can serve as a supply pipe 50, which enters the drain channel 53 between the outlet 54 and the pump 55. In this case, the siphon 15 is formed partially by the supply pipe 50 and partially by the drain channel 53.
