Appliance, especially domestic appliance

Description

[0001] The invention relates to an appliance, especially to a domestic appliance, comprising a water tank, wherein the water tank comprises a filling element for filling water into the water tank, wherein the filling element can be moved translational into a longitudinal direction between a first idle position and a second filling position, wherein an pulling element is arranged at an axial end of the filling element for pulling the filling element for translational movement along the longitudinal direction.

[0002] Especially in the case of steamers a water tank is required in the domestic appliance where water can be deposited to be used for the steam cooking process. In pre-known appliances the water tank has at least one handle for taking it out from the appliance to fill it with water. Also a handle can be arranged at the filling element to pull it out from an idle position into a filling position in which water can be filled into the water tank. After completion of the filling process the filling element can be pushed back from the filling position into the idle position.

[0003] The document EP 277 337 discloses an appliance comprising a water tank, wherein the water tank is provided as a drawer.

[0004] Thus the grip or handle for pulling out the filling element is arranged outside of the filling element itself and thus forms a part which disturbs the outer plane form of the panel. Thus, it is a drawback that the cleaning of the appliance is complicated in the region of the filing element as the grip or handle perturbs the cleaning operation.

[0005] Therefore, it is an object of the invention to propose a design for an appliance of the kind mentioned above which creates an improved appearance of the appliance especially in the region of the water tank and its filling element and to ensure in spite of this a proper handling of the appliance when filling the water tank.

[0006] The solution of this object is characterized in that the pulling element is arranged at or in the axial end of the filling element, wherein the pulling element can be arranged relatively to the filling element in an inner latching position and in an outer latching position, and wherein means (13) are arranged for preventing a relative rotational movement around the longitudinal direction (L) between the filling element (3) and the pulling element (4).

[0007] Preferably, a latch mechanism is arranged between the pulling element and the filling element. The latch mechanism comprises preferably a cam element with a cam surface and a boss being slidably arranged in the cam element to arrest the pulling element in the inner latching position and in the outer latching position. The cam element can be connected directly or indirectly with the filling element, wherein the boss can be fixed in longitudinal direction with the pulling element.

[0008] The filling element can have a substantial tubular shape with a cylindrical reception for the pulling element. The pulling element can have a knob at one of its axial ends and a cylindrical section for being inserted into the cylindrical reception of the filling element.

[0009] Furthermore, according to the present invention means are arranged for preventing a relative rotational movement around the longitudinal direction between the filling element and the pulling element. Those means can comprise at least one groove extending in the longitudinal direction and being arranged at the outer circumference of the pulling element or at the inner circumference of the cylindrical reception of the filling element, wherein at least one radially extending rib can be arranged at the inner circumference of the cylindrical reception or at the outer circumference of the pulling element, wherein the rib is designed to engage in a form-fitted manner into the groove. Preferably, it is specifically proposed that the at least one groove is arranged at the outer circumference of the pulling element and the at least one radially extending rib is arranged at the inner circumference of the cylindrical reception.

[0010] Additionally, means can be arranged to limit the maximum amount of relative displacement in longitudinal direction between the pulling element and the filling element. Those means can comprise at least one hook element which is arranged at the pulling element or at the filling element, wherein at least one reception can be arranged in the filling element or in the pulling element being designed for a form-fit engagement of the hook element. Preferably, it is specifically proposed that one single hook element is arranged at the pulling element and a corresponding reception is arranged in the filling element. The reception can be designed as a rectangular shaped cutout in the wall of the cylindrical reception of the filling element.

[0011] The outer surface of the pulling element and a panel of the appliance are preferably flush when the pulling element is in the inner latching position and when the filing element is in the idle position.

[0012] The appliance is preferably a steamer.

[0013] The proposed latch mechanism is preferably arranged as a "push-pull" mechanism in the filling element. Such latch mechanisms are known from other technology fields, e. g. in the field of ball-pens. Reference is made to US 6 113 160 concerning a latch where a cam element with a cam surface is shown by which a boss is guided to arrest a part relative to another in an inner and outer latching position.

[0014] The pulling element is incorporated into the filling element which can be easy done also in existing systems.

[0015] By the proposed concept a flush design can be obtained which makes is easy to clean the domestic appliance as no disturbing edges exist any more when the pulling element is in the inner latching position.

[0016] The means for limiting the displacement between the pulling element and the filling element allow to ensure that the latch mechanism is not put under tensile stress.

[0017] The means for preventing rotational movement between the filling element and the pulling element allow to reduce the tolerances between the mechanism and the filling element.

[0018] The panel with the filling element and the pulling element is in the idle position of the filling element and the inner latching position of the pulling element in a flush arrangement with the knob of the pulling element. Thus, an undisturbed surface is obtained on the panel front side leading to a positive appearance of the appliance.

[0019] In the drawings an embodiment of the invention is depicted.

FIG 8

shows an exploded view of a part of the pulling element with a latch mechanism.

[0020] In FIG 1 a domestic appliance 1 is shown only schematically which is a steamer in the present case. The steamer has a water tank 2. To fill the water tank 2 with water a filling element is used which is not depicted in FIG 1 as it is inside the water tank 2. Thus, the filling element is in an idle position IN in the water tank 2. At the end of the filling element a pulling element 4 is arranged, from which only a knob 11 can be seen in FIG 1. Here, the pulling element 4 is in an inner latching position I.

[0021] As can be seen the surface of a panel 20 of the steamer and the surface of the knob 11 flush and consequently, a flat surface is obtained in the position as shown in FIG 1 so that it is easy to clean the front of the panel 20.

[0022] In FIG 2 the same arrangement is shown, but here the filling element 3 for filling the water tank 2 is in its filling position OUT. Also the pulling element 4 is in its outer latching position II. Thus, the filing element 3 as well as the pulling element 4 have translational moved in a longitudinal direction L compared with FIG 1.

[0023] As can be seen the pulling element 4 is arranged at an axial end 5 of the filling element 3.

[0024] In the position as shown in FIG 2 water can easily be filled into the water tank 2 via the filling element 3. Water is poured into an opening 21.

[0025] In FIG 3 a demounted situation is shown. Here, the pulling element 4 is extracted from the filling element 3 which is here inside the water tank 2.

[0026] Details of the arrangement are apparent from FIG 4 to FIG 8.

[0027] In FIG 4 and FIG 5 is can be seen that the pulling element 4 has the knob 11 at one axial end and a cylindrical section 12 extending into the longitudinal direction L.

[0028] The filling element 3 has a hollow-cylindrical shape in one of its axial ends. Here a cylindrical reception 10 is formed. This reception is designed for insertion of the cylindrical section 12 of the pulling element 4.

[0029] Measures are taken to ensure that no relative rotational movement around the longitudinal direction L can take place. Therefore, means 13 are arranged comprising two grooves 14 at the outer circumference of the cylindrical section 12 of the pulling element 4 and corresponding ribs 15 which are formed in the cylindrical reception 10. Thus, the ribs 15 extend in the mounted state into the grooves 14 and prevent a rotational movement between the parts 3 and 4.

[0030] Also, means 16 are arranged to limit the relative translational displacement between the filing element 3 and the pulling element 4. Those means comprise a hook element 17 which is formed at a circumferential position of the cylindrical section 12 of the pulling element 4, wherein the hook element 17 extends radially outward. At the other hand a reception 18 is arranged in the wall 19 of the filling element 3 and in its cylindrical reception 10.

[0031] In the mounted state the hook element 17 is snapped into the reception 18 of the filling element 3, so that a maximum extend of relative translational movement is defined between the parts 3 and 4.

[0032] Those features can also be seen in FIG 6 and FIG 7. In FIG 6 the pulling element 4 is in its inner latching position I in the filling element 3. To the contrary, in FIG 7 the pulling element 4 is shown in its outer latching position II in the filling element.

[0033] With respect to the latch mechanism 6 which is employed reference is made to FIG 8. The latch mechanism 6 comprises a cam element 7 with a cam surface 8, in which a boss 9 is guided. The boss 9 is guided in a crank 22 which allows a movement transverse to the longitudinal direction L but no movement in longitudinal direction L. Thus, the knob 11 is guided between two latching positions I and II as explained before.

[0034] The function of the arrangement is as follows:

[0035] At first the arrangement is in the position as shown in FIG 1, i. e. the filling element 3 is in its idle position IN and the pulling element is in its inner latching position I.

[0036] To fill the water tank 2 the knob 11 is pressed inwardly so that the latch mechanism brings out the pulling element 4 in the outer latching position II as shown in FIG 2.

[0037] Now the pulling element 4 can be grabbed by the knob 11 and can be pushed in longitudinal direction L, so that the filling element 3 is also pushed out from the water tank 2 into its filling position OUT as shown in FIG 2.

[0038] Now, water can be poured into the opening 21.

[0039] When the water tank 2 is filled the pulling element 4 is pressed into the direction of the water tank 2 in longitudinal direction L. So, the filling element 3 is pushed into the water tank 2 again and also the pulling element 4 is pushed into its inner latching position I again. Thus, the status according FIG 1 is reached again.
