Description

[0001] The utility model relates to the design elements of small household appliances for the kitchen, in particular to the lids of electric kettles equipped with a hole for filling with water with a shutter, and can be used in the light industry in the production of kettles.

[0002] A prior art invention discloses a kettle lid (see information source RU 219072 U1, published June 28, 2023) comprising a housing with a water inlet, a closing mechanism, and a movable flap and a return spring. The return spring is a torsion spring containing an axle, and the length of the spring hooks allows the spring to withstand the load applied to the movable flap to tighten the spring.

[0003] A prior art (information source RU 2798458 C1, published June 23, 2023) describes an automatic top-fill system for an electric kettle, comprising: a lid with a water fill opening, a fill opening shutter, water flow recording devices directed toward the lid, a control board, and a power supply. The control board receives and processes data transmitted by the water flow recording devices, and, based on the processing results, generates control signals for opening and closing the shutter.

[0004] Also known from the prior art is information source RU 223363 U1, published on February 15, 2024, which discloses a kettle lid comprising a housing in which a water inlet is formed, a partition movably positioned beneath said water inlet, and a closing mechanism configured to exert an elastic drive force on the partition to ensure a tight and hermetically sealed closure of the water inlet by said partition, as well as to move the partition to open the water inlet under the action of the weight of the water. The kettle lid housing comprises a base with a filter element having a mesh structure and with stiffening ribs uniformly distributed over the base. The base is configured to be detachably connected to the kettle lid housing.

[0005] However, the disadvantage of all known technology is the rather complex design of the lid, the need to constantly open / close the lid, as well as unnecessary splashing of water when filling the kettle with water.

[0006] Thus, the objective of the claimed utility model is to eliminate the shortcomings of the known prior art.

[0007] The technical result, which the claimed utility model is aimed at achieving, is to ensure reliable, uninterrupted opening of the internal space of the kettle during its filling with water, maintaining the internal space of the kettle closed during the time when it is not filling with water, with a secure, hermetically sealed lid placed on the body of the kettle itself.

[0008] The teapot lid consists of a connected top section, main body, silicone seal, and bottom section, designed for hermetically sealed installation on the teapot. The bottom of the lid features a disc with a central opening. Three walls are evenly spaced around the perimeter of the opening. Together with the bottom disc, located on the undersides of the walls, they form three sealable filling openings. These openings are completely sealed by three rotary closures hinged to the edges of the opening. Metal weights are installed on the outer sides of the rotary closures.

[0009] The main body and the lower part of the cover are fixedly connected to each other by means of fixing holes and fixing protrusions, which are evenly distributed on the main body and the lower part, respectively.

[0010] There are protrusions on the outer side of the silicone seal.

[0011] The claimed utility model is further explained in more detail by drawings, in which:

[0012] Fig. 1 shows an exploded view of the claimed cover.

[0013] Fig. 2 shows the declared cover from the side and bottom.

[0014] Fig. 3 shows the claimed cover in section (without the silicone seal and the top part).

[0015] Fig. 4 (a, b) shows the operating principle of the rotary lid shutter.

[0016] In the figures shown, the elements of the claimed cover are designated by the following positions:

[0017] 1 - upper part,

[0018] 2 - main body,

[0019] 3 - silicone seal,

[0020] 4 - lower part,

[0021] 5 - rotary shutter,

[0022] 6 - metal weight,

[0023] 7 - supporting edge of the main body,

[0024] 8 - inner side of the main body,

[0025] 9 - inner rim of the lower part,

[0026] 10 - main body fixing holes,

[0027] 11 - lower part fixing tabs,

[0028] 12 - lower part disk,

[0029] 13 - walls of the lower part,

[0030] 14 - lower disc of the lower part,

[0031] 15 - lower filler holes,

[0032] 17 - valve hinge,

[0033] 18 - silicone seal protrusions.

[0034] The lid is designed for more convenient, safe, and reliable use of the kettle at home. Its design ensures the kettle remains closed while heating water, simplifying filling and reducing the risk of the lid accidentally shifting, falling out, or causing awkward interactions when pouring water or filling the kettle.

[0035] The stated lid is a structural element of the kettle, designed to be installed in the upper part of the kettle body and interact with the filling hole.

[0036] The upper part (1) is a flat element designed to accommodate and cover the filler hole of the lid by arranging its edges on the edges of the filler hole on the main body (2).

[0037] The main body (2) has a support rim (7) around its perimeter, which prevents the lid from falling into the teapot. The main body (2) also has an inner rim (8) designed to interact with the inner rim (9) of the lower part (4) of the lid. For this purpose, fixing holes (10) are uniformly formed on the inner rim (8) of the main body (2) around its entire circumference.

[0038] The lower part (4) of the claimed cover comprises an inner rim (9), on the outer side of which fixing projections (11) are uniformly formed around the entire circumference, corresponding to the fixing holes (10) of the main body (2) to ensure reliable and immovable fixation of the main body (2) and the lower part of the cover (4). The shapes and sizes of the fixing holes (10) and the fixing projections (11), as well as the distances between them, are made to correspond to each other for immovable fixation of the main body (2) on the lower part (4). Moreover, the fixing holes (10) are made identical, which allows fixing the main body (2) on the lower part (4) without special positioning, that is, any of the fixing projections can be placed in the fixing hole.

[0039] At the bottom of the lower part (4) of the cover there is a disk (12), in the middle of which there is a hole and on the bottom side of the disk (12) on the walls (13) a lower disk (14) is fixed, forming closing filling holes (15), which are closed by rotary valves (5), fixed hingedly on the edges of the hole of the disk (12) with the possibility of closing the closing filling holes (13).

[0040] In this case, the rotary valves (5) and the closing filling holes (15) are placed in pairs in the amount of three pieces and are located evenly along the perimeter of the lower disk (14).

[0041] A metal weight (6) is installed on the outer sides of each rotary valve (5), which ensures that the edges of the rotary valve (5) are pressed against the edges of the filling holes (15) to be closed.

[0042] The rotary valves (5) are fixed around the perimeter of the disk opening (14) using a detachable hinge (17), which allows one part to be separated from the other.

[0043] Figure 4b shows one rotary valve in operation as an example; in practice and everyday life, the rotary valves of the lid operate synchronously.

[0044] The location of the hinges in the upper parts of the rotary locks and the presence of metal weights ensures the durability and reliability of the lid, preventing jamming, hanging and loose fitting of the edges of the rotary locks to the edges of the filling holes being closed, ensuring a reliable and uninterrupted opening of the interior of the kettle during its filling with water, keeping the interior of the kettle closed when it is not filling with water.

[0045] The silicone seal (3) is a ring-shaped body placed on top of the upper body and the lower part connected to each other, and on the outside it contains protrusions (18) that ensure maximum fixation of the lid on the teapot.

[0046] The operation of the declared teapot lid is as follows:

[0047] The lid assembly is installed over the kettle's filler hole. When the kettle needs to be filled, remove the top section (1) and pour water into the filler hole. Water strikes the lower disc of the lid and, under the force of gravity, is directed along it to its edges, striking the rotary valves. Under the force of water pressure, the rotary valves rotate, opening the filler holes, and water enters the kettle. After the water supply to the lid's filler hole stops, the rotary valves, under the force of metal weights, return to their original position, closing the filler holes in the lid.

[0048] Thus, the stated lid ensures the closure of the internal space of the kettle when water is not poured into the kettle and the water does not splash and foreign objects do not get into it, and the process of filling the kettle is carried out without excessive splashes and swirls of water.

[0049] The inlet vents open automatically under water pressure and close automatically when the water supply stops. The mechanism operates smoothly, and the highly sealed design completely eliminates the typical drawbacks of standard lids: leaks, sticking, and incomplete closing.

[0050] Thus, the stated design of the lid increases the household value of the kettle, making it more convenient, safe and modern to use.

[0051] The claimed utility model is new, since the totality of its essential features is not known from the prior art, and, accordingly, meets the patentability condition of “novelty”.

[0052] The claimed utility model meets the patentability condition of "industrial applicability" since it can be used in industry.

[0053] Although the present utility model has been disclosed with reference to preferred embodiments thereof, this is not intended to limit the present utility model, and persons with general knowledge in the technical field of the present utility model can modify and implement it without departing from the idea and scope of the utility model, therefore, the scope of protection of the present utility model should be governed by the scope specified in the formula of the utility model.
