Description

[0001] Technical Field of the Invention

[0002] This invention relates to a device for heating liquids, such as an electric kettle or the like for water or other liquids. The invention also relates to a method for manufacturing a device for heating liquids.

[0003] Background Art of the Invention

[0004] It is known that devices for heating liquids (e.g., such as electric kettles) may include a container holding the liquid to be heated, and the heating device typically housed in the base of the device. The heating device may include, for example, one or more resistors housed in the base of the device, which may be connected to a power source if desired.

[0005] The container has a hole at the top to allow the filling of a liquid to be heated, and this hole can be closed by two or more types of lids. Two of the most common types of lids are typically present.

[0006] A first type of lid is provided, which is hinged to one side of the container and is adapted to present a lowered position for closing the container and an raised position for opening the container. The container may include a spout through which heated liquid flows out, and the spout is typically always open in both the lowered and raised positions of the lid.

[0007] Typically, the lid is associated with a locking system in the lowered position, which the user can activate, for example, by a button, to allow the lid to be released from the container, and then raised by rotating the lid around the hinge.

[0008] The second type of lid (specifically for electric kettles) is a hingeless safety lid, which is typically housed in a sealed manner over a hole at the top.

[0009] The cover is equipped with an open and close valve associated with a corresponding actuation system, which can be operated via a dedicated button. Typically, to return the valve to the closed position, the dedicated button needs to be pressed again.

[0010] These safety lids are also equipped with an additional button that allows them to detach from the container holding them.

[0011] Therefore, known devices for heating liquids require suitable containment devices and suitable systems and mechanisms for the lids they need to accommodate, depending on the type of lid they need to contain, to unlock and lock the lid in one case and open and close the valve in another.

[0012] Clearly, each known heating device needs to have specific structural features to accommodate one or another type of lid and one or another type of locking and unlocking system or opening and closing system for the valve that delivers the liquid.

[0013] If the lid is equipped with a delivery valve, the valve may be opened unintentionally, causing safety issues with the equipment, such as boiling liquid leaking from the container.

[0014] Therefore, in general, the above-mentioned types of devices for heating liquids are usually not very flexible in terms of possible use, the structure of the device is complex, and the safety aspects of the device also need to be improved.

[0015] Document EP2483745 describes various schemes for a device for heating liquids, including a safety cover with a delivery valve or a cover hinged to the central region of the liquid container. However, the described schemes are independent of each other and cannot be combined. Furthermore, in the case of the safety cover, the valve can only be opened when the device for heating the liquid is tilted to the liquid-pouring position.

[0016] Documents GB2486229A and DE29902995U1 describe other known types of devices for heating liquids.

[0017] Therefore, it is necessary to improve the equipment used for heating liquids so that it can overcome at least one of the disadvantages of the prior art.

[0018] Specifically, one object of the present invention is to provide a device for heating liquids (e.g., an electric kettle) that is efficient, safe and flexible in use.

[0019] Another object of the present invention is to provide a device for heating liquids, in which different types of lids can be associated with the same liquid container, and is characterized by its simplicity of construction and use.

[0020] Another object of the present invention is a method for manufacturing an apparatus for heating liquids, the apparatus being substantially equipped with a universal container, to which different types of lids (e.g., swivel lids, safety lids, or other lids) can be associated, depending on the different uses required.

[0021] The applicant has designed, tested and implemented the present invention to overcome the disadvantages of the prior art and to obtain these and other objectives and advantages. Summary of the Invention

[0022] The invention is set forth and characterized in the independent claims. The dependent claims describe other features or variations of the main inventive concept of the invention.

[0023] According to the above objectives, the apparatus for heating a liquid according to the present invention includes a container for the liquid and a device for heating the liquid in the container.

[0024] According to one aspect of the invention, the heating device includes a drive system configured to drive a plurality of different types of lids that may be alternatively housed on the container, wherein the drive system includes at least one activation element and at least one actuator, the at least one activation element being located outside the lid and being user-driven, and the at least one actuator being located inside the lid and cooperating with the activation element.

[0025] Driven by the activating element, the actuator moves between the first closed position and the second open position of the lid, or vice versa.

[0026] For example, in the case of a rotatable lid, the open state is understood as the lid rotating and rising relative to the container. Similarly, in the case of a safety lid, the open state is understood as liquid potentially flowing through a delivery valve, thus the delivery valve is at least partially open.

[0027] Preferably, the actuator engages with the valve in such a way that the valve can be opened regardless of the position and / or tilt of the container. In other words, the valve can be opened during liquid dispensing even when the container is in a substantially vertical position and does not need to be tilted.

[0028] Advantageously, current devices for heating liquids (e.g., electric kettles) essentially provide a universal container with different types of lids that can be alternatively associated with it, the lids being driven by a drive system. This drive system can be selectively driven to interact with at least a first rotatable lid and at least a second safety lid equipped with a valve.

[0029] The drive system is partially housed within the lid equipped with the actuator, and partially on the container equipped with a movable activation element that can be driven by the user. This activation element is adaptable to different types of lids and can drive actuators for different types of lids. The current heating device has proven to be highly flexible in terms of usability, efficient, and safe for the user.

[0030] The drive system is used to open the first rotatable lid relative to the container in the case of the first rotatable lid, and to open the valve at least partially in the case of the second safety lid.

[0031] According to some embodiments, the activating element may be associated with a resilient return mechanism. In this way, when the user releases the sliding member, the actuator can essentially return to its initial position, for example, the position where the first rotatable cover is closed or the valve is closed in the case of a second safety cover.

[0032] The first rotatable lid may be provided with a hinge for rotating from a first closed state of the container to a second open state, or vice versa. In this case, an actuator, acting as a constraint element between the first rotatable lid and the container, is associated with the first rotatable lid and configured to engage with the container to hold the first rotatable lid in the first closed state. An activation element is configured to act on the actuator and release the first rotatable lid from the container in the second open state.

[0033] The rotating hinge is located on the outer part and basically corresponds to the handle of the device used to heat the liquid.

[0034] According to some embodiments, the device for heating a liquid may include a flange for receiving a first rotatable cap, and an actuator may be configured to abut against the flange in the closed position of the first rotatable cap.

[0035] The device may also include a hinge mechanism positioned between the actuator and the activation element and configured to allow the actuator to move backward as the drive element is actuated, thereby allowing the first rotatable cover to be opened.

[0036] The hinge of the first rotatable lid may include a resilient device configured to allow the first rotatable lid to open automatically when the actuator is released from the container.

[0037] The lid that can be accommodated on the container, as described above, can also be a safety lid, which is provided with at least one liquid delivery valve; the valve includes an on / off switch and is in fluid communication with the interior of the container. In this case, the activation element is configured to push the actuator toward the on / off switch in such a way that at least partial opening of the valve is permitted.

[0038] The valve may include a resilient return mechanism that causes the opener to close automatically when the activating element is released by the user.

[0039] The safety cover includes a conduit with an inlet and an outlet for liquids, wherein the delivery valve is located inside the conduit.

[0040] The pipe is basically L-shaped, with a basically vertical first section and a basically horizontal second section, and the opener moves axially along the horizontal section.

[0041] The heating device may also be equipped with a fluid sealing device, which is positioned between the container and the safety cover.

[0042] Another object of the present invention is a method of manufacturing an apparatus for heating a liquid, the method comprising: providing a generally universal container provided with means for heating a liquid in the container; and providing a drive system that can be selectively driven to interact with a plurality of different types of lids that may alternatively be housed on the container, the plurality of different types of lids including at least a first rotatable lid and at least a second safety lid provided with a valve, wherein the drive system includes at least one activation element and at least one actuator, the at least one activation element being located outside the lid and being user-driven, and the at least one actuator being located inside the lid and cooperating with the at least one activation element, wherein driving the drive system opens the first rotatable lid relative to the container in the case of the first rotatable lid, and at least partially opens the valve in the case of the second safety lid, regardless of the position or tilt of the container.

[0053] For ease of understanding, the same reference numerals have been used to identify the same common elements in the figures where possible. It should be understood that elements and features of one embodiment can be readily incorporated into or integrated into other embodiments without further explanation. Detailed Implementation

[0054] We will now describe in detail possible embodiments of the invention by way of non-limiting illustration, wherein one or more examples are shown in the accompanying drawings. The wording and terminology used herein are also intended to provide non-limiting examples.

[0055] Referring to the accompanying drawings, for example, see Figure 1 and Figure 7 The device 10 for heating liquid according to the present invention includes a container 11 and a device (also referred to as a heating device) 12, the container being for the liquid and the device being for heating the liquid in the container 11.

[0056] The device 10 includes a drive system 13 configured to drive a variety of different types of lids 14 or 15, which can be alternatively accommodated on the container 11.

[0057] These caps include at least a first type of rotatable cap 14 (this type is called "flip-top") and a second type of safety cap 15 (airtight seal to prevent liquid leakage).

[0058] The drive system 13 includes at least one activation element 16 and at least one actuator 17 or 18. The at least one activation element is located outside the cover 14 or 15 and can be driven by the user. The at least one actuator is located inside the cover 14 or 15 and cooperates with the activation element 16.

[0059] Activating element 16 can be, for example, a cursor that moves in a linear direction (e.g., as shown in the image). Figure 1 , Figure 3 , Figure 4 and Figure 7As shown), or according to possible variations (not shown), it may be a button or lever suitable for moving downwards from the top or by horizontal pivoting or other means.

[0060] As the activating element 16 is driven, the actuator 17 or 18 moves between a first position where the cover 14 or 15 is in a first closed state and a second position where the cover 14 or 15 is in a second open state, or vice versa.

[0061] In the case of the second type of cover 15, as will be described, the open state for conveying liquid is represented by at least partial opening of valve 19.

[0062] In other words, in the case of the rotatable lid 14, the drive activation element 16 causes the rotatable lid to open relative to the container 11, and in the case of the safety lid 15, causes the valve 19 to open at least partially.

[0063] The container 11 may be provided with an upper hole 38, and a lid 14 or 15 is accommodated in the upper hole 38, and the upper hole allows for the filling or addition of liquid.

[0064] Container 11 may also be provided with a container spout 20 for liquid outflow, through which liquid can be conveyed as container 11 is tilted appropriately.

[0065] The container 11 may also include a gripping handle 21, which is preferably positioned on the side opposite to the side where the container spout 20 is located.

[0066] The heating element 12 of the device can be located at the lower part of the container 11, and the heating element can be integral with the container 11. For example, the heating element 12 may include one or more resistors or the like.

[0067] The base 22 is typically associated with the container 11 which is equipped with a power supply device, and the base 22 is then connected to the electrical network via cables and plugs.

[0068] According to some embodiments, the device 10 also includes a temperature control device, such as a thermostat 57, which is configured to deactivate the heating device 12 when the liquid reaches boiling. A through passage (also referred to as a passage or via) 58 may also be provided, through which steam generated in the container 11 during boiling can reach the vicinity of the thermostat 57, thereby shutting off the heating device 12.

[0069] According to some embodiments, the activation element 16 can be moved, translated away from or toward the cover 14 or 15 in such a way, or can be moved in a rotatable manner and cooperate with the actuator 17 or 18 by a suitable transmission element.

[0070] The activation element 16 may be associated with a resilient return device (also referred to as a resilient device) 23. The resilient device 23 allows the actuator 17 or 18 to move from a second position to a first position by returning the activation element 16 to its original position. In this way, the cover 14 or 15 can essentially be moved from an open state to a closed state.

[0071] In the case of the first type of rotatable cover 14, this passage appears after the rotatable cover 14 is lowered.

[0072] The activation element 16 may include a drive button 24 located outside the container 11 and a shaft 25 located inside the container 11 and integrated with the button 24. The shaft 25 is associated with a resilient return mechanism 23.

[0073] The activation element 16 can be guided by a suitable translation guide manufactured in the container 11. For example, a ring 26 for guiding the shaft 25, a guide for translating the activation element 16 (and thus for translating the button 24 manufactured on the outer surface of the container 11), or other similar elements may be provided. The shaft 25 may be at least partially exited from the base 53 manufactured in the container 11, or the shaft may be recessed into the base.

[0074] The rotatable lid 14 may be provided with a hinge 28 for rotating from a first closed state of the container 11 to a second open state of the container 11, or vice versa.

[0075] The hinge 28 may be provided on the outer portion of the hole 38, preferably corresponding to the handle 21.

[0076] The activating element 16 is configured to cooperate with the actuator 17, in which case it acts as a constraint element between the rotatable lid 14 and the container 11.

[0077] Actuator 17 is connected to rotatable lid 14 and configured to engage with container 11 to keep rotatable lid 14 in a first closed state. Activation element 16 is configured to act on actuator 17 and release rotatable lid 14 from container 11 in a second open state.

[0078] The closed state of the rotatable cover 14 is as follows Figure 1 As shown, in Figure 1 When the rotatable cap 14 is lowered, the actuator 17 engages with the container 11, and as the container 11 is tilted appropriately, liquid can flow out from the container spout 20 of the container 11.

[0079] exist Figure 3 or Figure 4 In the open state, the rotatable cap 14 is opened instead, to allow operations such as filling or adding liquid, or other operations.

[0080] Specifically, a flange 29 can be placed on the hole 38 of the container 11 to accommodate the rotatable lid 14, so that the rotatable lid 14 can fit perfectly into the container 11.

[0081] According to some embodiments, such as those described with reference to FIG2a, the edge of container 11 and flange 29 may be provided with mutual coupling devices 54.

[0082] The coupling device 54 may include hook teeth 55 protruding from the side wall of the flange 29, which are adapted to be inserted into a suitable base 56 disposed on the inner surface of the container 11 and corresponding to the upper edge of the hook teeth.

[0083] According to other embodiments of the invention, flange 29 can be attached by other methods, such as screws, rivets, welding and / or adhesives.

[0084] A sealing gasket (not shown) may be provided to prevent possible liquid leakage.

[0085] According to these embodiments, the actuator 17 may be adapted to be positioned against the flange 29 in the closed state of the rotatable cover 14, thereby preventing the cover 14 from rotating about the hinge 28.

[0086] For example, actuator 17 may be positioned at least partially below flange 29, such as Figure 1 As shown.

[0087] In the absence of flange 29, with the rotatable cover 14 closed, actuator 17 can be positioned inside a hole in the wall of container 11, against a step or other protruding element in the interior of container 11, or in a similar manner.

[0088] The actuator 17 may also be housed within a sliding guide 30 manufactured inside the rotatable cover 14. The actuator 17 may also be provided with an end of travel element 31 adapted to abut against the guide 30 when the rotatable cover 14 is closed.

[0089] A hinge mechanism 32 may be placed between the actuator 17 and the activation element 16, which is configured to allow the actuator 17 to move backward as the activation element 16 is driven (e.g., pressure is applied to the activation element 16), thereby allowing the rotatable cover 14 to be opened.

[0090] The hinge mechanism 32 may include, for example, a pair of connecting rods 33 and 34, which are rotatably constrained on opposite sides of a disc 35, which is rotatably attached to the interior of a rotatable cover 14.

[0091] The first connecting rod 33 can be rotatably connected to the actuator 17, and the second connecting rod 34 can be rotatably constrained to the rod 36, which is adapted to cooperate with the shaft 25 of the activation element 16. Specifically, connecting rods 33 and 34 are rotatably constrained to the disk 35, corresponding to the periphery of the disk 35.

[0092] The hinge 28 may also be equipped with a resilient device 37, which is configured to allow the rotatable lid 14 to open automatically when the actuator 17 is released from the container 11.

[0093] Considering Figure 1 With the rotatable cover 14 in the closed state, the user can press the activation element 16 in such a way that the activation element translates in the A1 direction against the action of the elastic device 23 (if configured). Through this appropriate movement, the translation of the activation element 16 in the A1 direction causes the actuator 17 to... Figure 1 The position moved backward Figure 3 The actuator is positioned such that it is essentially embedded in the rotatable cover 14. Therefore, the rotatable cover 14 can be... Figure 1 The position rose to Figure 4 The position. Due to the elastic device 37 of the rotating hinge 28, this raising can occur automatically.

[0094] When the user releases the activation element 16, the activation element 16 can return to its original position due to the elastic device 23. Figure 1 The actuator 17 retracts a section from the rotatable cover 14 (specifically from the guide 30 manufactured in the rotatable cover 14), see [reference]. Figure 4 For this purpose, actuator 17 may be equipped with its own resilient return mechanism that pushes the actuator out of guide 30 and thus out of rotatable cover 14.

[0095] To close the rotatable lid 14 again, the user will need to lower the rotatable lid by rotating it around the hinge 28 and press the activation element 16 again in the A1 direction so that the actuator 17 is inserted into the rotatable lid 14, and then release the activation element 16 so that the actuator 17 engages with the container 11 again (e.g., below the flange 29).

[0096] Figure 5 A safety cover 15 is shown, which is provided with at least one liquid delivery valve (also referred to as a valve as above) 19, which is in fluid communication with the interior of the container 11. An activation element 16 is configured to push an actuator 18 toward the on / off switch 39 of the valve 19, thereby allowing the valve to be opened.

[0097] exist Figure 5In this situation, the safety cover 15 is closed, meaning the liquid delivery valve 19 is closed. Figure 6 On the other hand, the safety cover 15 is in the open position, that is, the valve 19 is open, allowing liquid to flow to the container spout 20 of the container 11 as the container 11 is properly tilted.

[0098] Valve 19 may include a resilient return device (also referred to as a resilient device) 40, which determines the automatic closure of the opener 39 when the activating element 16 is released and thus the actuator 18 returns to its initial position.

[0099] The safety cover 15 is accommodated on the container 11 by a fluid sealing device 41 (such as a suitably shaped gasket or the like).

[0100] If the liquid contained in container 11 is at a high temperature, and therefore an accidental spillage of the liquid from container 11 could be dangerous, a safety cap 15 can be used.

[0101] In this case, the actuator 18 may include a rod having a first end 43 that cooperates with the shaft 25 of the activation element 16 and a second end 42 that cooperates with the on / off switch 39 of the valve 19.

[0102] A conduit 44 is fabricated in the safety cover 15, which is provided with an inlet 45 and an outlet 46 for liquid. A valve 19 is located between the inlet 45 and the outlet 46. The valve 19 has an on / off switch 39 that can open or close the passage 48 fabricated in the conduit 44. The on / off switch 39 will be provided with a fluid sealing device 47, such as at least one O-ring or the like.

[0103] According to some embodiments, the conduit 44 is substantially L-shaped, having a substantially vertical first section 44a corresponding to the inlet 45 and a substantially horizontal second section 44b corresponding to the outlet 46.

[0104] Valve 19 is preferably disposed in the second section 44b, and the opener 39 moves axially along an axis coaxial with the second section 44b.

[0105] A through hole 59 may be provided in the first section 44a, which allows the actuator 18 to pass through.

[0106] In any state of use, that is, in any position of container 11, actuator 18 is preferably always engaged with opener 39 in such a way that it is adapted to open valve 19, regardless of the tilt of the container.

[0107] According to some embodiments, the first segment 44a and the second segment 44b are arranged orthogonally to each other. According to other variations (not shown), their tilt angle can be between about 70° and about 110°.

[0108] According to some embodiments, as the activating element 16 is driven, the shaft 25 and the opening / closing device 39 move axially, substantially parallel to and / or coaxially with each other, along their respective axes.

[0109] The user can open valve 19 by acting on activating element 16 in the A1 direction. Shaft 25 associated with activating element 16 will abut against first end 43 of actuator 18, causing actuator 18 to translate, thereby displacing the opener / closer 39 and opening passage 48. See [link to relevant documentation]. Figure 5 and Figure 6 .

[0110] By releasing the activation element 16, the elastic return device 23 will move the activation element 16 from... Figure 6 The location brought to Figure 5 The position, and the opener 39 will return to its closed position due to the elastic device 40 (also causing the actuator 18 to return to its position). Figure 5 The location of (the position).

[0111] For the two types of lids 14 or 15 shown, it can be seen that the activation element 16 of the drive system 13 is independent of the type of lid mounted on the container 11. Furthermore, the actuator 17 or 18 is located inside the lid 14 or 15 and is substantially independent of the activation element 16. The activation element 16 can act on the actuator 17 via the hinge mechanism 32 (as in the case of the first type of rotatable lid 14) or directly on the actuator 18 (as in the case of the second type of safety lid 15).

[0112] See Figure 7 and Figure 8 The safety cap 15 is equipped with a lower portion 49 suitable for insertion into the container 11 and a closed upper portion 50. In the lower portion 49, teeth 51 may be placed for hooking the safety cap 15 into a base 52 manufactured in the container 11.

[0113] The tooth 51 can be configured to enter or exit the sidewall of the lower portion 49, and the tooth can be provided with a resilient device that holds the tooth in the position protruding from the lower portion 49. When the lid 15 is inserted into the container 11, the tooth 51 first engages in the lower portion 49, and then, when the tooth reaches the position corresponding to the base 52, the tooth quickly ejects and enters at least a certain section of the base 52.

[0114] The safety cover 15 may, for example, be equipped with a key 27 or button in the upper portion 50, which is configured to engage the teeth 51 inside the lower portion 49, thereby allowing the safety cover 15 to be released.

[0115] According to other embodiments, the safety cover 15 may include a second passageway configured to fluidly communicate the interior space of the container 11 with the passageway 58.

[0116] The method of manufacturing a device 10 for heating liquid according to the present invention includes: providing a generally universal container 11, which is provided with means 12 for heating liquid in the container 11; and providing a drive system 13 as described above to drive a variety of different types of lids 14, 15 that may be alternatively housed on the container 11.

[0117] It is clear that modifications and / or additions can be made to the heating device as described above without departing from the scope and range of the invention as defined in the claims.
