Description

Water dispenser for washing machines

The present invention relates to a device using water, in particular, a water dispenser for a washing machine.

According to German Patent Publication No. 19 13 868, wash water is supplied at an angle to each other from two controllable water supply valves so that the operation of the water supply valves is individually or simultaneously controlled, a water dispenser is provided which forms a jet or resultant jet. The resulting jets are used to supply the wash water to a fabric softener input chamber that is configured in the water dispenser and arranged below the water dispenser. If another detergent dispenser is to be configured in the water dispenser, another water dispenser valve must be provided to supply the wash water directly to the detergent dispenser.

When washing water is to be supplied to the detergent dispensing chamber according to DE 38 22 392 for the purpose other than supplying the washing water to the detergent dispensing chamber, the washing water supplied to the detergent dispensing chamber is disturbed by the branch pipe , Another water valve is needed. Therefore, the prior art method of supplying wash water by the branch pipe is impractical. Only when a special water valve is additionally provided can the additional constructed feed path be reliably controlled.

It is therefore desirable to provide an apparatus in which at least five feed passages within the water dispenser can be controlled by three water valves.

According to the present invention, when the jets of the wash water flowing out from the water supply valves are directed to the intersection and are controlled individually according to a program and have two or more water supply valves, the direct jets of the wash water The water supply dispenser for washing machines according to claim 1, wherein the water supply dispenser is provided for each water supply line and, when the wash water is simultaneously supplied, the jets resulting from the wash water are supplied toward the middle water supply path, Wherein the jets of wash water flowing out of the feed water channel controlled by one of the formed jets and another water valve form another second intersection and are arranged in the second position of the second intersection along the flow direction of the jet, And a water supply dispenser for washing machines characterized in that the intersection portion has three water supply passages.

Thus, the wash water is separately supplied to the five water lines by the three connectors. The principles disclosed in document DE 19 13 868 can be extended. For example, seven water lines are supplied with wash water by four connection pipes, or five water lines are supplied with wash water by five connection pipes. However, during the formation of the resultant jets, since the dispersing jets flowing into the water lines arranged close to the water lines are generated, only the water channels connected to the dispensing chambers, which have already been emptied according to the operation program of the washing machine, The water supply valves of the connectors must be controlled.

Wherein the water dispenser has three controllable connection tubes, the water supply path for the washing water and direct jet supplied from the third connection pipe of the connection pipes is guided to the second intersection, Three water lines are provided on the rear of the intersection. In this case, the resultant jet of the second crossing portion is supplied to the distribution room for the fabric softener, and the pressure of the washing water supplied to the distribution room for the fabric softener is lowered to the distribution room of the preliminary laundry detergent, Is less than the pressure of water. The pressure of the washing water supplied to the preliminary laundry detergent powder and the laundry detergent powder in the powder state is larger than the pressure of the washing water supplied to the fluid softening agent and when the contents of the distribution compartment rise above the receiving wall, Can be changed. For example, if the dispersing jets flowing into the other two feed passages are supplied only to the distribution room previously supplied with the wash water, such as the distribution room of the preliminary laundry detergent or the distribution room of the present laundry detergent, Is supplied to the path of the number.

According to an embodiment of the present invention, four connection tubes are mounted on the rear wall of the cover for a housing of a detergent container having four insertion chambers for storing detergents metered by the user, The two connecting tubes are arranged at an acute angle to the first intersection, and the first intersection is arranged in the empty air passage. The second intersection is formed by the arrangement of the washing water and the first intersection supplied from the third connection pipe and three water paths are formed in the rear of the second intersection along the flow direction of the washing water.

According to the present invention, the water supply passage arranged in the middle from the first intersection is guided to the distribution chamber in the lid, and the dispersion holes directed to the bleach introduction chamber arranged below the distribution chamber are formed in the distribution chamber, The water feed channel is guided from the connecting pipe to the outlet pipe, the wash water is directly supplied to the washing tub by the outlet pipe, the water feed channel for direct jet is guided from the connecting pipe to the second crossing portion via the connecting water channel, And another water channel of the second intersection for direct jetting is guided to the distribution chambers and the dispersion holes for the detergent input chamber and the fiber softener input chamber arranged below the distribution chamber are connected to the distribution . According to the configuration of the present invention, only three connection pipes are used for five wash water, four wash water out of the five wash water is supplied to the detergent input chambers of the detergent container, For example, the laundry is directly supplied to the laundry and supplied in advance to the laundry so that the laundry introduced from the charging opening of the front loading type washing machine can be wetted relatively more quickly by the washing water.

Using the intersections where the wash water is diverted (jets resulting from the intersecting wash water) and the intersections arranged in front of and behind each other, the number of controllable water passages is increased to five. The five water lines are used to supply the wash water to the four dispensing chambers and to supply the wash water directly to the wash basin. The intersections and dispensing chambers must be arranged such that the wash water that is lost and dispersed by the intersections flows along a straight path and flows into the dispensing chambers already supplied with wash water. When each of the water supply valves is operated, three of the five water supply passages can flow without the loss or dispersion action of the wash water. Except for the water supply valve, no moving parts are configured in the dispenser of the wash water, so the possibility of failure is minimized. At the same time, by controlling the washing water supplied to the five water supply lines, the washing water can be directly supplied to the washing tub independently from the program step, and the laundry can be separately prewetted by the washing water.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A1, A2, A3, A4, A5:

Referring to Fig. 1, a basic arrangement of a water dispenser 7 according to the invention is shown. A valve block (V) having an inlet pipe (E) for supplying wash water and electronically controlled water supply valves (1,2,3) is connected to a water supply dispenser, and wash water (4,5,6) (7). The wash water 5,6 meet at the first intersection 8 and the water supply passages A3 and A5 and the connection water path 9 are connected to the first intersection 8. The wash water 4 of the water supply valve 1 and the connection water path 9 meet at the second intersection 10 and the water supply passages A1, A2 and A4 are connected to the second intersection 10 . When the wash water of the water supply valves 1, 2 or the water supply valves 2, 3 is supplied simultaneously, the resultant jets 23, 24 at the second intersection 10 and the first intersection 8, And feed passages A4, A5 for the resulting jets 23, 24 are provided. In this case, two jets with roughly the same intensity are applied to the straight path at each intersection and collide, forming the resulting jets which collide with the intervening feed passages A4, A5. The resulting jets are formed by about 50% of the flow of the two incoming jets and the jets of the remaining flow quantities are divided into two dispersion jets having approximately the same flow volume, (See FIG. 2). A2, A3, A4, and A5 to supply wash water to at least the detergent input chambers (VWK, HWK), the fabric softening agent input chamber (WSK), and the bleach input chamber (BK) Can be used.

Referring to the table of FIG. 2, the amount of wash water flowing into each water supply channel when one or two of the water supply valves is opened is indicated. The arrangement of each input chamber associated with the flow in each feedwater path from within the water dispenser is provided in the table of FIG. The detergent input chamber VWK of the laundry detergent is connected to the water supply line A1 and the detergent input chamber HWK of the present laundry detergent is connected to the water supply line A2, And an outflow pipe 15 in an empty state is connected to the water supply passage A3.

When the wash water is supplied from the water supply valves 1 and 2, the resultant water is supplied in the form of a resultant jet, and the wash water of 50% or more of the supplied water is supplied to the water supply line A4, And is supplied into the input chamber (WSK). The dispersing jets of 25% or less of the supplied water amount pass through the detergent dispensing chamber (VWK) and the detergent dispensing chamber (HWK) and before the washing water is supplied to the fabric softening agent dispensing chamber (WSK) HWK), the dispersion jets do not cause unnecessary problems.

When the wash water is supplied from the water supply valves 2 and 3, the resulting water is supplied in the form of a resultant jet, and more than 50% of the supplied water is supplied to the water feed path A5, And the dispersing jets of which 25% or less of the supplied water amount are supplied to the water feed passages A2 and A3 and the washing water is supplied to the detergent input chamber HWK or the outflow pipe 15 through the water feed passages A2 and A3, . The washing water is supplied to the detergent input chamber HWK of the main washing detergent and the washing water is directly supplied into the washing tub of the washing machine by the outlet pipe 15 before the washing water is supplied to the bleacher input chamber BK, While the washing water is supplied to the bleacher input chamber (BK), the dispersion jets do not cause unnecessary problems.

An embodiment of the water dispenser 7 shown in Fig. 1 is shown in Fig. 3 and a washing machine detergent container 17 is shown in Fig. 4, a detergent container 17 is guided to a housing which is sealed by a cover 16 (see Fig. 3) on a pressurized detergent container, and the detergent container 17 has input chambers. Four input chambers for detergents to be metered by the user are a detergent dispenser (VWK) for the laundry detergent, a detergent dispenser (HWK) for the main detergent, a fabric softener dispensing compartment (WSK) for the fabric softener, A bleach bleeder input chamber (BK) for bleach is constituted in the detergent container (17). When the detergent container 17 is pushed into the housing, a detergent dispensing chamber (VWK) is arranged below the dispensing chamber (VKV) for the preliminary laundry detergent, and the detergent dispensing chamber (VKH) A yarn HWK is arranged and a fabric softening agent feed chamber WSK is arranged below the distribution chamber VKW for the fabric softener and a bleach input chamber BK is arranged below the distribution chamber VKB for bleaching agent. The supplied laundry water flows into the insertion chambers under the distribution chamber through the dispersion holes formed in the base of the distribution chamber and flows backward toward the cavity (not shown in the figure) connected to the detergent container by the detergent and the elastic tube of the insertion chambers .

The connection tubes 11, 12, 13, 14, 20 and the outlet tube 15 are arranged in the rear wall 19 of the lid 16. The two adjacent connecting pipes 12 and 13 are arranged at an acute angle to each other and the air passage 21 in the empty state for preventing washing water from flowing back toward the first intersection 8 is connected to the first intersection 8). Air flows through the air passage 21 when negative pressure is formed inside the connection pipe 12 or the connection pipe 13 and air is supplied to the bottom portion of the water passage including the first intersection 8 through the air passage 21 Is provided. The connection pipe 11 is directed to the second intersection 10 together with the connection water path 9 extending from the connection pipe 12 and the backflow prevention hole 22 for preventing the washing water from flowing backward, (11). The connection pipe 14 is connected to the washing machine through a cavity, and discharges the portion of the washing water formed in the pressurized outlet pipe of the washing machine. The connection tube 20 is closed in a closed state and can be used for various purposes.

The washing water supplied from the connection pipe 11 flows into the water supply line A1 and flows from the water supply line A1 to the distribution room VKV of the laundry detergent solution. The wash water supplied only to the connection pipe 12 flows to the water feed passage A2 through the connection water path 9 and flows to the distribution chamber VKH of the laundry detergent from the water feed passage A2. The washing water supplied only to the connection pipe 13 flows into the water supply passage A3 and is directly supplied to the outflow pipe 15. The hose connected to the washing and passing pipe is connected to the outflow pipe 15. [ For example, the hose is connected to an inlet door of a front loading type washing machine.

The resultant jet 23 of the wash water supplied simultaneously from the connecting tubes 11 and 12 meets at the second intersection 10 and the resultant jet 23 is supplied to the water feed passage A4, A4) to fill the distribution room VKW of the fabric softening agent. The resulting jet 24 is directed to the first intersection 8 and the resultant jet 24 flows into the water supply passage A5 and the water And the bleaching agent dispensing chamber (VBK) is filled from the furnace A5.

The water dispenser is not limited to the arrangement of FIG. 1 and the table of FIG. 2 or the embodiments of FIGS. 3 and 4. The water dispenser can be used for all appliances for which wash water must be supplied by a relatively small number of water supply valves to three or more water passages. Without departing from the spirit of the present invention, the embodiment of FIG. 1 with three water valves and five water lines can be enlarged to an embodiment with four or five water valves. When four water valves are provided, seven water channels are provided, and if five water valves are provided, nine water valves can be provided. For example, if four water supply valves are provided, two connection water paths extending from the water supply valves are directed toward the third intersection similar to the connection water path 9 connected to the water supply valve 2 of FIG. Next, the third intersection has three water paths. If five water valves are provided, the intersections and waterways are similarly connected. As the distance between the water line and the water valves increases, the pressure in the water line decreases, so a greater number of water valves and intersections are undesirable.

Because the feed passages can be used or arranged differently, the arrangement of the feed passages and intersections shown in Figures 3 and 4 is optional. When the water supply passage A3 and the discharge pipe 15 are not required to be connected to the inside of the detergent container through separate water supply lines, the outflow pipe 15 is removed, and the water supply passage A3 is opened And is directly extended to the inside.
