water filter

technical field

The invention relates to a water filter, comprising a raw water container for holding water to be filtered, a water outlet, a filter assembly and a mounting surface for placing a clean water container, the filter assembly is arranged in the following manner, and the water to be filtered flows in the The outlet process flows through the filter assembly.

Background technique

It is known to use a water filter to improve the water quality, especially the water quality of tap water. Raw water is passed through a water filter before drinking. In connection with kettles, water boiling devices have been developed which have two containers which are separated by an actual filter. One of the containers is for raw water and the other container is for clean water. Such a water boiling device also has a heating mechanism for heating cleaning water. Such a water boiling device is disclosed by DE19861175B4 or GB2294631A, for example. In these known water boiling devices, operation is laborious due to the size of the device.

In addition to these boilers, which should be considered as complete units, boilers are also known whose kettles can be separated by a filter unit. EP1028090A1 describes such a water boiling device. The water boiling device has a filtering device, which includes a raw water container and a clean water container. The raw water container is placed above the clean water container. The filter unit is equipped with a pump and a tap as water outlet. A pump is used to deliver clean water to the spout located above the jug. Furthermore, a power supply unit is an integral part of the water boiler, via which the electric current required to drive the heating mechanism belonging to the kettle is supplied to the kettle, which can be removed from the power supply unit. The lid of the kettle has a water filling port, and when the kettle is placed on the power supply unit, the water filling port is located below the outlet of the faucet. The job of the pump is to fill the jug with clean water.

In this known water filter, the components involved are matched to one another in terms of their size and functionality. Consequently, this water filter is ultimately only suitable for filling the container associated with the water filter.

Contents of the invention

Starting from the above-mentioned prior art, the task of the present invention is to improve the water filter of the same type as described above, so that it can not only work without current in the case of a simple structure, but also can use it to add water to containers of different sizes .

According to the invention, this task is accomplished by a water filter of the same type as described above, wherein:

- the raw water container is placed at a height higher than that of the water container,

- the seating surface is the upper surface of the foot,

- the raw water container is connected to the feet in a height-adjustable manner by brackets fixed to the feet,

- the placement surface is equipped with a plurality of fixing elements protruding upwards from the placement surface for enclosing the bottom of the container, at least one of which is adjusted in relation to its distance from the other or another fixing element in order to adapt to the diameter of the bottom of the container Language is adjustable.

In this water filter machine, the raw water container is placed at a height higher than the water storage container. In this water filter machine, the raw water filtration operation and its output to the container for clean water rely on gravity. Therefore, in principle, there is no need to use electrical components to complete the water filtration operation. The raw water container is held on the stand in a height-adjustable manner. The support itself is connected with the support feet, and the upper surface of the support feet is exactly the placement surface for the clean water holding container. The height adjustability of the raw water container or its water outlet allows the height of the water outlet to be adjusted according to the height of the water filling port used to fill the container. In this case, the filling opening can be an upper opening in the container, an opening in the container lid or a container mouth. In order to fix or keep the clean water container, the placement surface has a plurality of fixing pieces protruding upward from the placement surface. These holders are used to grip the bottom of the container. The container bottom can be the bottom side of the container or a power supply unit assigned to the container. The container is detachably arranged on the power supply unit. In the latter case, the clean water container involves a jug. These fastening elements can be designed in the form of claws and are used to place the container to be filled with clean water on the mounting surface according to the regulations, so that the raw water container or its water outlet is on the mounting surface and thus opposite to the filter unit. The water outlet is in the prescribed configuration.

In order to adapt the area of the mounting surface clamped by the fixing elements to the base diameter or bottom diameter of the container to be filled with cleaning water, at least one of the fixing elements is adjustable with respect to its distance from the other or another fixing element. In this way, the proper placement of the container on the mounting surface can be achieved independently of the diameter of the container to be filled with cleaning water. According to a first embodiment, at least one fixing element is fixed, with respect to which one or other fixing element is adjustable with respect to its distance from said at least one fixed fixing element. Such fixed mounting elements or preferably two mounting elements which are slightly spaced apart from one another are preferably used as adjustment marks for placing the cleaning water container in the correct orientation on the mounting surface. Such a design is suitable when the container should be filled with water through the mouth. The purpose of the alignment mark is to indicate the direction in which the container's spout should be oriented toward the center of the mounting surface, such that water flowing from the spout flows into the upwardly open spout. Such adjustment markings are also useful if containers with different diameters are to be placed properly if they are to be filled with water through the upper opening.

Another embodiment provides that all fastening elements, preferably in the form of claws, are adjustable relative to the center of the mounting surface. In such a design, each container placed on the mounting surface is centered relative to the mounting surface independently of the diameter of the container. In such a design, each container can be filled from the same outlet state through its upper side opening, regardless of what diameter the container has. In order to move these fixed parts radially displaceable with respect to the center of the mounting surface in unison, a control disc can be provided, whereby the individual fixed parts are coupled to each other via a crescent control mechanism. The control disc is adjustable about an axis of rotation which passes through the center of the seating surface. For adjusting the control disc, preferably an operating lever protruding radially outward from the control disc is used, which can be equipped with a knurled hand piece on the outside. Through such an operating member, the control panel can be moved in one direction or in the opposite direction for moving the fixing member away from the center of the placement surface or toward the center of the placement surface. The length of the crescent groove control mechanism simultaneously limits the stroke of the fixing member.

According to one embodiment, the height adjustability of the raw water container relative to the rest surface is accomplished by means of an adjustment wheel acting on the support. The adjustment wheel can be part of the raw water container. It is also possible that the adjusting wheel is in the form of a separate unit which, when accommodated in a housing, can be adjusted in its longitudinal direction relative to the support on which the raw water container is supported. Along with the height adjustment of the adjustment wheel, the raw water container will also rise and fall. The latter design is especially suitable for swinging the raw water container relative to the support about the longitudinal axis of the support. This pivotability of the raw water container can be used if the fixing part is to be adjusted centrally relative to the mounting surface and the water is to be filled through the mouth. Because the raw water container and its water outlet can swing, so for containers with different diameters, it can adapt to the different distances between the mouth opening and the center of the placement surface. A refinement of this solution provides that the pivoting of the raw water container relative to the support and thus also relative to the mounting surface is controlled by means of a restoring spring. Via the return spring, the raw water container and its water outlet are pressed onto the stopper. In this state, the water outlet of the raw water container has the shortest distance from the center of the placement surface with respect to the possible stroke of the raw water container. If a container with a larger diameter is placed on the mounting surface, the raw water container and container mouth move away from the stop against the force of the spring. Thus in this embodiment, if there are containers of different diameters which should be filled with water through their mouths, such containers are automatically adapted.

The adjusting wheel, which acts on the support for adjusting the height of the raw water container relative to the mounting surface, preferably has teeth which mesh with complementary teeth of the support. The toothing of the setting wheel then serves on the one hand as a knurled setting surface for turning the setting wheel and on the other hand for moving the setting pull in the toothing of the carrier in the form of a toothed bar. The adjusting wheel expediently has a locking mechanism for locking the adjusting wheel. As locking mechanism, for example, a spring-loaded plunger can be used which acts on the side of the setting wheel or engages in a recess of the setting wheel. Only when the push rod has left the adjustment wheel against the spring force, the adjustment wheel can rotate to adjust the height of the raw water container.

According to a preferred refinement, the water filter is designed for filling the container formed on the mounting surface via a mouth. It is then expedient for the container to have a mouth sufficiently large for this purpose, such as is customary for modern jugs. Occurred in such design is provided with self-closing valve in water outlet, and self-closing valve overcomes spring force to open with container mouth. In such a water filter, therefore, water can only flow out of the water outlet when a container whose mouth acts on the valve has been placed on the mounting surface. If the water filter is not placed in the specified direction, it will not be possible to add water. As a result, an undesired escape of water or bypassing of cleaning water through the container is avoided. This is advantageous where the clean water container is an electric kettle, essentially a kettle with a power supply unit separable from the actual kettle. In this design, therefore, there is no danger that water that does not flow out properly could reach the electrical components of the power supply unit.

Detailed ways

The water filter 1 includes a support foot 2 , a bracket 3 fixed on the support foot 2 and a filter unit 4 . The filter unit 4 is used to filter raw water so that clean water can be delivered from the filter unit as required. The water filter 1 is designed according to the size of various clean water containers. For this purpose, the water filter 1 has a foot 2, the upper surface of which is designed in the form of a mounting surface 5 for receiving a container to be filled with clean water. In order to securely place such a container on the mounting surface 5 , the foot 2 has three claws 6 , 6 ′ and 6 ″ in the form of fixing elements. These claws 6 , 6 ′ and 6 ″ protrude upwards from the mounting surface 5 And is used to hold the base or bottom of the container to be filled with clean water. The jaws 6 , 6 ′ and 6 ″ are radially adjustable with respect to the center 7 of the mounting surface 5 , which can be indicated, for example, by the double arrow assigned to the jaw 6 . The jaw 6 is described below. The jaw 6' and 6" have the same construction. The claw 6 has a clamping body 8 located above the placement surface 5, and a guide body 9 is integrally formed thereon. The guide body 9 can be guided radially in a radially extending crescent 10 , which is indicated, for example, by the aforementioned double arrows. The guide body 9 snaps behind a plate 11 forming the mounting surface 5 so that the claws 6 are held on the plate by the clamping body 8 and the part that snaps onto the plate 11 . The plate itself is part of a housing 12 of which the whole of the foot 2 is indicated by reference 12 . The plate 11 is an annular body, the center of which is closed by a closing plate 13 . The cover plate 13 is detachable from the foot 2 in the shown embodiment and is decisively used for the following purpose. When the cover plate 13 is removed, the jaws 6, 6' and 6" move into the crescent groove 10, for example to As can be seen from the boundary diagram of the support foot 2 shown in Figure 2. The sealing plate 13 taken off from the housing 12 in this figure represents the opening pointing to the center of the crescent groove 10. In the guide body 9 of the claw 6 On the top, a guide pin 14 is integrally formed protruding downward (see Figure 3), and the guide pin is inserted into the crescent groove 15 of the control panel 16. The crescent groove 15 is formed in the form of a spiral notch, so that one end of the crescent groove 15 is separated from the placement surface The distance of 5 center 7 is less than the distance of its other end apart from this center. Operating rod 17 radially protrudingly is integrally formed on the control panel 16. On the free end of operating rod 17, handpiece 18 is housed. The outer surface of handpiece 18 With knurling.

The cooperation between the guide pin 14 and the claw 6, 6', 6" guide body 9 can be seen from the housing 12 of the leg 2 shown in Figure 3. The operating rod 17 passes through the outer peripheral surface of the housing 12 The seam 19. The hand piece 18 is located outside the seam 19. Therefore, the control disk 16 can be rotated in one direction or the opposite direction by the movement of the hand piece 18 in the seam 19, wherein according to the movement of the control disk 16, the claw 6 , 6' and 6" are adjustable in terms of their mutual distance and thus their distance from the center 7 of the mounting surface 5. The crescent groove 15 is identically formed for all jaws 6 , 6 ′ and 6 ″, so that each jaw 6 , 6 ′ or 6 ″ is moved with the same stroke towards the center 7 or away from the center when the control disk 16 is adjusted 7.

The filter unit 4 is placed on the support 3 . The filter unit 4 has a groove for receiving the upper end of the bracket 3 . The filter unit 4 is supported with its bottom side on the upper side of the adjustment mechanism 20 . Therefore, the filter unit 4 is adjusted in terms of its height relative to the foot 2 when the adjustment mechanism 20 is adjusted relative to the support 3 .

The adjustment mechanism 20 includes an adjustment wheel 21 supported in a housing 22 . The adjustment wheel 21 is provided with teeth 23 on the outside, whereby on the one hand a certain adhesion is created to allow the adjustment wheel 21 to turn and on the other hand the teeth mesh with complementary teeth 24 provided in the outer surface of the bracket 3 . By turning the adjusting wheel 21 , the adjusting wheel can be moved in the direction of the longitudinal axis of the carrier 3 in the toothing 24 which works like a rack. The structure of the adjustment mechanism 20 can be seen from the sectional views of FIGS. 4A and 4B . The adjusting mechanism 20 is equipped with a locking mechanism, by means of which the adjusting wheel 21 can be locked. The locking mechanism in the illustrated embodiment results in a self-locking of the adjusting wheel 21 when the adjusting wheel is not moved. The locking mechanism comprises a locking pawl 25 which has a recess on its side facing the side 26 of the setting wheel 21 . The side face 26 of the setting wheel 21 has correspondingly complementary recesses, the purpose of which is to engage the locking pawl 25 in the side face 26 of the setting wheel 21 in a form-fitting manner in the direction of rotation of the setting wheel 21 . For this reason, the groove is formed radially with respect to the axis of the setting wheel 21 . The locking pawl 25 is connected to the actuating part 28 via a clip 27 . The clip 27 can be passed around the adjustment wheel 21 on the upper side. An actuating element 28 protrudes from the housing 22 of the adjusting mechanism 20 (see FIG. 1 ). The clip 27 is acted on by a compression spring 29 which itself is supported on the inside of the housing 22 of the adjustment mechanism 20 and which presses the locking pawl 25 against the side 26 of the adjustment wheel 21 by means of this compression spring in order to lock the adjustment wheel. . Therefore, in order to actuate the setting wheel 21 , the actuating member 28 must be pressed in to disengage the mutual toothing between the locking pawl 25 and the complementary recess in the side 26 of the setting wheel 21 (see FIG. 4B ). The height adjustment of the adjustment mechanism can then be achieved relative to the frame by turning the adjustment wheel 21 or by moving the adjustment wheel along the frame. If the actuating element 28 is released, the adjusting wheel 21 is automatically locked, and as a result, the adjusting mechanism 20 is locked relative to the bracket 3 (see FIG. 4A ).

The filter unit 4 comprises a raw water container 30 , the upper side of which is closed by a cover 31 . A support extending downwards for accommodating the filter assembly is opened in the bottom surface of the raw water container. There is a water outlet under the filter assembly, so that the unfiltered water in the raw water container 30 can flow out after passing through the filter assembly. The water outlet has a self-closing valve. Water outlet valve is opened by means of valve control cover 32 against spring force. In the state shown in FIG. 1 of the valve control cover 32, the water outlet valve is closed. The valve-operated cap 32 is operated by the mouth of the clean water container.

The filter unit 4 is pivotable about the longitudinal axis of the support 3 relative to the support and the adjustment mechanism 20 . A possible swivel path of the filter unit 4 is indicated by the symbol D in FIG. 1 .

In order to adjust the water filter 1 for the container placed on the placement surface 5, in addition to clamping the jaws 6, 6' and 6" of the placement surface actually required at that time and the adjustment mechanism 20 for adjusting the height of the filter unit 4, Markings 33 provided on the outer surface of the housing of the filter unit 4 are used.

FIG. 5 shows a water filter 1 including an electric kettle 34 placed on the surface 5 of its feet 2 . The kettle 34 has a power supply unit 35 on which the kettle 34 is detachably arranged. The claws 6 , 6 ′ and 6 ″ are adjusted by means of the manual element 18 in relation to the diameter of the power supply unit, so that the claws and thus the jug 34 are arranged centrally with respect to the mounting surface 5 . To adjust the height of the filter unit 4 , the jug 34 and its spout Be placed on the outer surface of the housing of the filter unit 4, as shown in Figure 5. Subsequently, the filter unit 4 is adjusted in terms of its height relative to the spout 36 of the jug 34 by means of the adjustment mechanism 20. The marking 33 is used for this purpose. The unit 4 is adjusted to such a height that the mark 33 representing the shadow of the spout is at the same height as the upper end of the spout 36 of the kettle 34. Through the opening 37 of the spout 36, cleaning water is added to the kettle 34. For this purpose, the kettle 34 Then enter the position shown in Figure 6, in this position, the front of the mouth 36 acts on the valve control cover 32 of the filter unit 4 and opens the water outlet valve.As shown in Figure 1, the valve control cover 32 has a contour, so that the mouth 36 can be clearly positioned in it. Therefore, when the kettle 34 is in its position as shown in Figure 6, its mouth 36 acting on the valve operating plate 32 is in a position where the water flowing out of the water outlet Cleaning water flows into the opening 37 of the mouth 36 .

In order to compensate the different distances acting on the front end of the mouth of the valve 32 in jugs or other containers with different diameters, as shown in FIG. In the illustrated embodiment, the pivoting of the filter unit 4 indicated by the arrow in FIG. 6 is accomplished against the spring force by which the filter unit 4 tries to move in the direction opposite to the direction indicated by the arrow. This spring pretension acts on the spout 36 of the kettle when the kettle 34 is resting on the foot 2 , which causes the valve actuating lid 32 to open. At the same time, this automatically adapts to the distance A of jugs of different sizes or other devices in which clean water is to be filled.
