The bottom of the lower housing 50 is inclined downward toward the outlet 51 in such a way that water for Laundry located in building 40, easily flows to the outlet 51. In the upper parts of both sides of the lower housing 50 are the guide rails 52, serving to give direction with the introduction of container 70 in the lower casing 50 or extension from the enclosure.

The container 70 for detergent has an open top and an open rear end. The container 70 is formed by the input cavity 72, 73 and 74 for detergent, which are separated from each other by a dividing wall 71, so that the input cavity 72, 73 and 74 individually downloading various types of detergents. The input cavity 72, 73, 74 detergent formed in the longitudinal direction of the container 70 for detergent so that these cavities 72, 73, 74 correspond to the channels for water flow, respectively 61A, 61b and 61c. The bottom of the container 70 for detergent inclined downward from its front end to the rear end.

Water for washing is supplied from node 30 to supply water passes through the inlet cavity 72, 73, 74 detergent before the water is introduced into tank 11 for washing. At this time, the detergent loaded in the input cavity 72, 73, 74, mixed in water for washing, passing through the inlet cavity 72, 73, 74, and water containing detergents, served in the water tank 11.

More precisely, the water supplied to the container 70 for detergent through the channels 61A, 61b, 61c water formed in the upper housing 40 is injected into the input cavity 72, 73, 74 detergent on top of the input cavities 72, 73, 74, and the water then flows to the rear parts of the input cavities 72, 73, 74 along the inclined bottom parts of the input cavities 72, 73, 74. At this time, the detergent loaded in the input cavity 72, 73, 74, mixed in water for washing. Water for washing containing detergents, served in the water tank 11 through the open rear ends of the input cavities 72, 73, 74 for cleaning means and an outlet opening 51 in the housing 40.

As shown in figure 3, at least one of the input cavities 72, 73, 74 for detergents (for example, the input cavity 74) is designed in such a way that in the input cavity 74 selectively load powder or liquid detergent. In the input cavity 74 detergent is the control element 80, which is connected to both sides of the input cavity 74 and moves down to increase the time during which the liquid detergent remains in the input cavity 74 when in the input cavity 74 load liquid detergent, and a control element 80 is moved upward when the input cavity 74 load powder detergent. The control element 80 has a height which is less than the height of the input cavity 74 for detergent.

According to the first presented as a variant example of implementation of the present invention, the guide grooves a for vertical movement formed vertically in the upper parts of both sides of the entrance cavity 74 for detergent. Each of the guide grooves a has a specified length on the vertical axis and guides 81 to move vertically formed in the upper parts of both ends of the control element 80. Guides 81 of the control element 80, respectively engages with upravlyayuschimi grooves a input cavity 74 for the detergent so guides 81 are moved vertically along the guide grooves a to give a direction vertical movement of the control element 80.

The control element 80 serves to control the flow of detergent into the input cavity 74 to increase or decrease the time during which the detergent remains in the input cavity 74, providing the selective loading of liquid or powdered detergent in the input cavity 74 and uniform mixing of the detergent loaded in the input cavity 74, the water for washing, passing through the detergent container.

As described above, the bottom part of the input cavity 74 for detergent tilted down to its rear end, the rear end of the input cavity 74 is open. Therefore, when the liquid detergent is loaded in the input cavity 74, such detergent immediately flows to the outlet 51 of the housing 40. In the liquid detergent will not be evenly mixed in the water for washing entered in the input cavity 74. According to presented as a variant example of implementation of the present invention the control element 80 is located in the input cavity 74 for detergent. Therefore, when the input cavity 74 load liquid detergent, operated the speaker element 80 is moved down to increase time during which liquid detergent remains in the input cavity 74 in front of a control element 80.

If the water for washing is served when the control element 80 is moved down towards the bottom part of the input cavity 74 for detergent, as described above, the liquid detergent is mixed in water for washing entered in the input cavity 74 for detergent before a control element 80, and then it flows to the outlet 51 of the housing 40 above the upper end of the control element 80. When this liquid detergent loaded in the input cavity 74, evenly mixed in the water for washing entered in the input cavity 74, and then will be submitted to the tank 11.

On the other hand, when the input cavity 74 load powder detergent, the control element 80 is moved upward so that the distance between the lower end of the control element 80 and the bottom part of the input cavity 74 is maximized. In this case, powdered detergent, loaded in the input cavity 74, will be evenly mixed in the water for washing entered in the input cavity 74, and then is smoothly filed in the water tank 11.

When the control element 80 is maximally moved upward, guides 81 for vertical movement are located respectively at the upper ends e.g. the engaged grooves a for vertical movement. When the control element 80 is maximally displaced downwards, guides 81 are respectively the lower ends of the guide grooves a. Preferably, but not necessarily to guides 81 for vertical movement were tightly fitted respectively in the guide grooves a, so that the control element 80 is held in the highest or in the lowest position.

When the control element 80 is moved down to the bottom of the input cavity 74 for the detergent guides 81 for vertical movement preferably, but not necessarily, will engage respectively with the guide grooves a, so that the control element 80 will not rotate around guides 81 through liquid detergent or water for washing in the input cavity 74.

This presents the embodiment, the design of the control element 80 is located between the front end and an open rear end of the input cavity 74 for the detergent and the lower end of the control element 80 is in contact with the bottom part of the input cavity 74 when the control element 80 is maximally displaced downwards, so that the liquid detergent in front of a control element 80, will not leak to the rear of the input cavity 74 for washing among the STV before water washing. However, the control element 80 may be located near the open rear end of the input cavity 74 so that the liquid detergent is completely absorbed in the input cavity 74. In addition, the control element 80 may be located so that the lower end of this element 80 will be somewhat distant from the bottom of the input cavity 74 when the control element 80 is maximally displaced downward if it satises the presence of liquid detergent before a control element 80 within a specified period of time.

Next described will be performed in a washing machine load operation of detergent and water supply in the case of using the site for feeding detergent according to the first variant implementation of the present invention.

Guides 81 for vertical movement, made in the control element 80, forcibly enter respectively into the guide grooves a input cavity 74 for the detergent to position the control element 80 in the input cavity 74 so that the control element 80 is able to move vertically. After that, in the case 40 is inserted container 70 for detergent.

When the user wants to load liquid detergent in the container 70, he puts the container 70 from the housing 40, and then pushes the control element 80 located the military in the input cavity 74 for the detergent down, so that the control element 80 will move downward until the lower end of the control element 80 is not in contact with the bottom part of the input cavity 74. At this time, the guides 81 on guide element 80 are respectively located at the lower ends of the guide grooves a that is maintained as long as the user will not pull the control element 80 upwards.

After the user has downloaded a liquid detergent into the input cavity 74 in front of a control element 80, he wdiget container 70 for detergent into the housing 40. At this time, liquid detergent, loaded in the input cavity 74 in front of a control element 80, remains in the input cavity 74 and does not occur immediately over to the back of the input cavity 74.

When in the above-mentioned able to supply water for washing, the water supplied through the valves 21 and 22, is introduced into the host 30 for supplying detergent to the feed pipes 23a, 23b, 23c and through the inlet a, 62b, s node 30 for supplying detergent. Water for washing is introduced into the host 30 for supplying detergent pump in the input cavity 74 through one of the channels 61A, 61b and 61c. At this time, the liquid detergent in the input cavity 74 are evenly mixed in the water for washing entered in the input cavity 74 in front of a control element 80, flows to the rear h the particular container 70 for detergent through the upper end of the control element 80 and then will be submitted to the water tank 11 through the outlet 51 of the housing 40.

When the user wants to load into the container 70 powdered detergent, he puts the container 70 from the housing 40, and then pulls the control element 80 located in the input cavity 74, upward, so that the lower end of the control element 80 will defend from the bottom of the input cavity 74 for detergent. At this time, the guides 81 for vertical movement performed on the control element 80, respectively, are located at the upper ends of the guide grooves a, and this location will be saved up until the user pushes the control element 80 down.

After the user has downloaded the powdered detergent in the input cavity 74, he inserts the container 70 for detergent into the housing 40. When in this state to supply water for washing, powder detergent that is in the input cavity 74, evenly mixed in the water for washing entered in the input cavity 74, and flows to the rear of the container 70 and then will be submitted to the water tank 11.

Figure 6-11 shows the node for supplying a detergent according to the second, presented as a variant example of implementation of the present invention. The second option is identical to the first embodiment except for design changes control and modification of the output cavity for detergent according to constructive change control. Accordingly, the components of the node for supplying a detergent according to the second variant of implementation of the designs, which correspond to the components of the node for supplying a detergent according to the first variant of implementation of the design, are denoted by the same positions as in the node for supplying a detergent according to the first variant of the design.

As shown in Fig.6 and 7, the input cavity 74 for detergent designed so that the cavity 74 selectively load powder or liquid detergent. In the input cavity 74 is a control element 180 that is connected to both sides of the input cavity 74 so that the control element 180 is moved down to increase the time during which the liquid detergent remains in the input cavity 74 when in the input cavity 74 load liquid detergent, and a control element 180 is moved up when the input cavity 74 load powder detergent. On both sides of the entrance cavity 74 for detergent, respectively, are elements 90, serving to prevent separation of the control element 180 from the input cavity 74.

The elements 90 are designed to surround both ends of the control element 180, when the control element 180 is moved in the vertical is. The elements 90 are inside from both sides of the input cavity 74 for detergent. Each of the elements 90 includes upper edge 91 to maintain the upper end of the control element 180, maximally moved upward, to prevent separation of the control element 180 from the input cavity 74 for detergent, the first lateral edge 92 that is located prior to a control element 180 or behind him to prevent separation of the control element 180 from the input cavity 74 for detergent, the second side edge 93, located on the back or front of the control element 180 to prevent separation of the control element 180 from the input cavity 74 for detergent. In the following description of the first lateral edge 92 is located prior to a control element 180, and the second side edge 93 is located behind the control element 180.

In the upper part of both sides of the input cavity 74 for detergent in the elements 90 are vertically formed guide grooves 75, serving to give direction when the vertical movement of the control element 180, each of the vertical grooves 75 has a predetermined length in the vertical direction. Accordingly, the control element 180 is provided in the upper parts of both sides of his guides a for vertical displacement is of, which engages with the guide groove 75 so that the guides I will be given direction along the guide grooves 75, when the control element 180 is moved vertically.

When the liquid detergent is loaded in the input cavity 74, which is formed so that the bottom part of the cavity 74 is tilted down to the back of this cavity 74, and the rear end of the input cavity 74 is open, liquid detergent immediately flows to the outlet 51 of the housing 40. In the liquid detergent unevenly mixed in water for washing entered in the input cavity 74 for detergent. According to presented as a variant example of implementation of the present invention the control element 180 is moved down when the input cavity 74 load liquid detergent, while the liquid detergent will remain in the input cavity 74 in front of a control element 180.

If the water for washing is served when the control element 180 is moved down towards the bottom part of the input cavity 74, the liquid detergent mixed with water for washing entered in the input cavity 74 ahead of the control element 180, and then flows to the outlet 51 of the housing 40 over the upper end of the control element 180. Thus, liquid detergent, downloaded what about the input cavity 74, evenly mixed in the water for washing entered in the input cavity 74, and then will be submitted to the water tank 11.

On the other hand, when the input cavity 74 load powder detergent, the control element 180 is moved upwards so that the distance between the lower end of the control element 180 and the bottom part of the input cavity 74 for detergent will be maximized. In this case, powdered detergent, loaded in the input cavity 74, evenly mixed in the water for washing entered in the input cavity 74, and then is smoothly filed in the water tank 11.

The control element 180 includes a moving vertical plate 181, the two lateral ends of which support both lateral sides of the input cavity 74 for detergent to prevent flow of liquid detergent to the outlet 51 of the housing 40. When the control element 180 is maximally moved down, moving vertical plate 181 is in contact with the bottom part of the input cavity 74 for detergent to prevent flow of liquid detergent to the outlet 51 of the housing 40.

In the middle part of the lower end of the moving vertical plate 181 formed part a for forming a predetermined gap between the plate 181 and the bottom part of the output cavity 74 for the detergent when the plate 181 is in contact with the bottom part of the input cavity 74. The gap formed in such a way that after a large part of the liquid detergent will be submitted to the water tank 11, mixing in water for washing, the remaining portion of the liquid detergent, which remains at the bottom of the input cavity 74 in front of a control element 180 may be issued from the input cavity 74. If the gap is very large, then a large part of the liquid detergent can flow from the inlet cavity 74 before water washing. Therefore, part a forming the gap, preferably, but not necessarily, designed so that the liquid detergent will remain in the input cavity 74 in front of a control element 180 for a period of time longer than the specified period.

Each of the guide grooves 75 for vertical movement contains the upper end of the groove 75A formed at the upper end for location therein of the respective guide a, when the control element 180 is maximally moved upward, the lower end of the groove 75s formed at the lower end for location therein of the respective guide a, when the control element 180 is maximally displaced downward, the connecting groove 75b located between in the rhna end groove 75A and a lower end groove 75s. The upper end of the groove 75A and the lower end of the groove 75s recessed to a greater extent than the connecting groove 75b, so that guides a for vertical movement remain near the top end of the groove 75A or lower end of the groove 75s, when the control element 180 is maximally moved upward or downward. At the lower end portion of the upper end of the groove 75A and the upper end portion of the lower end of the groove 75c respectively formed inclined portion 75d, which is inclined to the connecting groove 75b for smooth giving directions when moving guide a to the connecting groove 75b. On both sides of the upper rear surface plate 181 for vertical movement formed plate 182 forming the projections that pass from the plate 181 to the second side edges 93 along both sides of the input cavity 74 for detergent, so guides a for vertical movement respectively formed in the plates 182, forming ledges. The plates 182 around guides a for vertical movement formed by the cut out portion 182b to maintain elastic state guides a.

When the control element 180 is maximally moved upward or downward, guides a will be located in the upper end of the groove 75A and in the lower end of the groove 75s, which are absorbed to a greater extent than the connecting groove 75b. Therefore, the control element 180 is supported in a fixed position until such time as the user performs a forced displacement of the control element 180 in the opposite direction.
