Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a base assembly of an electric kettle and an electric kettle. Background Art

[0002] With the improvement of people's living standards and the acceleration of the pace of life, more and more household appliances have entered consumers' families to meet various different needs of people, and the functions and application scenarios of such household appliances have become increasingly refined to enhance consumers' usage experience. For example, in order to prevent problems such as dry burning of electric kettles, some electric kettles with weight control functions have emerged. However, in actual use, the dry burning function often fails due to inaccurate weighing of the water volume in the kettle. Summary of the Utility Model

[0003] In view of this, the utility model provides a base assembly of an electric kettle and an electric kettle to solve the problem of inaccurate weighing of the water volume in the kettle.

[0004] In the first aspect, the utility model provides a base assembly of an electric kettle, including:

[0005] A panel structure provided with an installation through-hole;

[0006] A coupler, which is floatably arranged at the installation through-hole. The coupler includes a main body portion and a surrounding edge arranged along the circumference of the main body portion. The main body portion is adapted to be coupled with the bottom of the kettle body, and the surrounding edge is located above the panel structure and blocks the installation through-hole;

[0007] A support plate, which is fixed to the lower side of the panel structure. The support plate is provided with a relief hole;

[0008] A weighing sensor, including a fixed end and a deformation portion. The fixed end is fixed to the support plate, the deformation portion can move along the relief hole, and the weighing sensor is arranged below the coupler.

[0009] Beneficial effects: When the kettle body is placed on the base assembly, the bottom of the kettle body is coupled with the coupler. Since the kettle body and the water in the kettle body have a certain weight, a downward pressure will be generated on the coupler. Since the weighing sensor is arranged below the coupler, the deformation portion of the weighing sensor will move downward with the coupler and deform. Since the support plate is fixed to the lower side of the panel structure and the fixed end of the weighing sensor is fixed to the support plate, the fixed end of the weighing sensor remains stationary, and the deformation portion of the weighing sensor deforms relative to the fixed end. The weight of the water in the kettle body is different, and the amount of deformation of the deformation portion is different. Therefore, the water volume in the kettle body can be accurately measured. Since the weight of the kettle body is directly transmitted to the weighing sensor and is less affected by external interference, the measurement accuracy can be improved.

[0010] Since the coupler includes a main body portion and a surrounding edge disposed circumferentially around the main body portion, the surrounding edge is located above the panel structure and blocks the mounting through-hole. The surrounding edge functions to block water, preventing water from entering the inside of the kettle base assembly through the mounting through-hole and causing danger. Moreover, since the coupler integrates the surrounding edge, the number of components is reduced, which can improve the assembly efficiency.

[0011] In an alternative embodiment, the upper surface of the surrounding edge is an arc surface or a conical surface, and the end of the surrounding edge away from the main body portion is lower than the end connected to the main body portion.

[0012] Advantageous effects: Since the upper surface of the surrounding edge is an arc surface or a conical surface, and the end of the surrounding edge away from the main body portion is lower than the end connected to the main body portion, when water falls on the upper side of the surrounding edge, it can flow downward along the surrounding edge, avoiding water from entering the inside of the kettle base assembly through the mounting through-hole and causing danger.

[0013] In an alternative embodiment, the kettle base assembly further includes a fixing plate, and the fixing plate is fixed below the coupler and fixedly connected to the deformation portion.

[0014] Advantageous effects: The fixing plate is fixed below the coupler and fixedly connected to the deformation portion. The fixing plate functions to connect the coupler and the deformation portion. Since the area of the fixing plate is relatively large, it is convenient to connect the fixing plate to both the coupler and the deformation portion.

[0015] In an alternative embodiment, the fixing plate includes a mating portion that abuts against the deformation portion, and a clearance portion that is located above the fixed end and has a gap with the fixed end.

[0016] Advantageous effects: The mating portion abuts against the deformation portion. When the kettle body is placed on the kettle base assembly, the bottom of the kettle body is coupled to the coupler. Since the kettle body and the water inside the kettle body have a certain weight, they will drive the fixing plate to move downward together, and drive the deformation portion of the weighing sensor to move downward. The fixed end of the weighing sensor remains stationary. Since the clearance portion has a gap with the fixed end, it can ensure that the fixing plate can move downward relative to the fixed end of the weighing sensor, and the deformation portion of the weighing sensor deforms relative to the fixed end, thereby achieving accurate weighing.

[0017] In an alternative embodiment, fixing posts are provided on the lower side of the main body portion, and fixing holes are provided on the fixing plate, and the fixing posts are fixedly connected to the fixing holes.

[0018] Advantageous effects: By providing fixing posts on the lower side of the main body portion and fixing holes on the fixing plate, and fixedly connecting the fixing posts to the fixing holes, the fixing plate is fixedly connected to the coupler.

[0019] In an alternative embodiment, the support plate is provided with a mounting position, and the fixed end of the weighing sensor is fixed to the mounting position.

[0020] Advantageous effects: By providing a mounting position on the support plate, it is convenient to position and install the weighing sensor.

[0021] In an alternative embodiment, a surrounding rib is provided on one side of the support plate facing the coupler. The surrounding rib protrudes from the surface of the support plate, and the inner side of the surrounding rib forms the mounting position.

[0022] Advantageous effects: By providing a surrounding rib on one side of the support plate facing the coupler, the surrounding rib protrudes from the surface of the support plate, and the fixed end of the weighing sensor is limited and fixed inside the surrounding rib. The surrounding rib can limit the fixed end of the weighing sensor to prevent the position of the weighing sensor from moving.

[0023] In an alternative embodiment, a plurality of fixing parts are provided at the edge of the support plate, and a plurality of connecting columns protrude from the lower side of the panel structure. The connecting columns are fixedly connected to the fixing parts.

[0024] Advantageous effects: By providing a plurality of fixing parts at the edge of the support plate and a plurality of connecting columns on the lower side of the panel structure, and the connecting columns are fixedly connected to the fixing parts, enough space is formed between the support plate and the panel structure to accommodate the weighing sensor and the fixing plate.

[0025] In an alternative embodiment, the panel structure includes a panel and a panel bracket. The panel bracket is supported below the panel. The panel is provided with a first through hole, and the panel bracket is provided with a second through hole. The second through hole is coaxially arranged with the first through hole, and the first through hole and the second through hole form the mounting through hole.

[0026] Advantageous effects: The panel structure includes a panel and a panel bracket. The panel bracket is supported below the panel, which can ensure that the upper surface of the kettle base assembly is flat and beautiful. The first through hole and the second through hole form the mounting through hole, which can ensure that the coupler can move up and down in the first through hole and the second through hole.

[0027] In an alternative embodiment, the center of gravity line of the coupler coincides with the force axis of the weighing sensor.

[0028] Advantageous effects: By making the center of gravity line of the coupler coincide with the force axis of the weighing sensor, the water volume in the kettle body can be measured more accurately.

[0029] In a second aspect, the present invention further provides an electric kettle, including:

[0030] A kettle body and the kettle base assembly as described above.

[0031] Beneficial effects: For this electric kettle, when the kettle body is placed on the kettle base assembly, the bottom of the kettle body is coupled with the coupler. Since the kettle body and the water inside the kettle body have a certain weight, a downward pressure will be exerted on the coupler. Since the weighing sensor is provided below the coupler, the deformation part of the weighing sensor will deform as the coupler moves downward. Since the support plate is fixed to the lower side of the panel structure and the fixed end of the weighing sensor is fixed to the support plate, the fixed end of the weighing sensor remains stationary, and the deformation part of the weighing sensor deforms relative to the fixed end. With different weights of the water in the kettle body, the amount of deformation of the deformation part is different. Therefore, the amount of water in the kettle body can be accurately measured. Since the weight of the kettle body is directly transmitted to the weighing sensor and the external interference received is relatively small, the measurement accuracy can be improved. Since the coupler includes a main body part and a peripheral edge arranged along the circumference of the main body part, the peripheral edge is located above the panel structure and blocks the installation through hole, and the peripheral edge has the function of blocking water, which can prevent water from entering the inside of the kettle base assembly through the installation through hole and causing danger. Moreover, since the coupler integrates the peripheral edge, compared with the related technology, the number of parts is reduced, and the assembly efficiency can be improved.

Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0046] With the improvement of people's living standards and the acceleration of the pace of life, more and more household appliances have entered consumers' homes to meet various different needs of people, and the functions and application scenarios of such household appliances have become increasingly refined to improve consumers' usage experience. For example, in order to prevent problems such as dry burning of electric kettles, some electric kettles with weight control functions have emerged. However, in actual use, the dry burning function usually fails due to inaccurate weighing of the water volume in the kettle.

[0047] Related technology discloses a weighing-controlled automatic electric kettle, including: a kettle body, including a kettle body and an electric heating module, the electric heating module is arranged at the bottom of the kettle body; a heating seat, including a base and a coupler, the coupler is arranged below the electric heating module, and the coupler supplies power to the electric heating module; a control module, including a weighing sensor and a central control system, the weighing sensor is arranged below the coupler, and the weighing sensor and the coupler are electrically connected to the central control system. The heating seat also includes a coupler upper pressing ring and a coupler lower pressing ring, the coupler upper pressing ring and the coupler lower pressing ring are respectively provided with an upper through hole and a lower through hole for installing the coupler, the lower part of the coupler is fixed on the coupler lower pressing ring, the coupler upper pressing ring is fixed on the coupler, and the upper part of the coupler passes through the upper through hole, corresponding to the electric heating module; the weighing sensor is installed at the bottom of the coupler lower pressing ring, and its weighing sensing part corresponds to the lower through hole.

[0048] In the above-mentioned related technology, the upper part of the coupler is fixed to the upper pressing ring of the coupler, and the upper pressing ring of the coupler covers the electric socket hole. The number of parts is large, which makes the installation process complicated.

[0049] Combine the following Figures 1 to 10 , describing an embodiment of the utility model.

[0050] According to an embodiment of the utility model, on the one hand, a kettle base assembly of an electric kettle is provided, comprising a panel structure, a coupler 3 , a support plate 5 and a weighing sensor 6 .

[0051] Among them, the panel structure is provided with a mounting through hole; the coupler 3 can be floated at the mounting through hole, the coupler 3 includes a main body 301 and a surrounding edge 302 arranged along the circumference of the main body 301, the main body 301 is suitable for coupling with the bottom of the kettle body 4, the surrounding edge 302 is located above the panel structure and blocks the mounting through hole; the support plate 5 is fixed to the lower side of the panel structure, and the support plate 5 is provided with a clearance hole 501; the weighing sensor 6 includes a fixed end 601 and a deformation part 602, the fixed end 601 is fixed to the support plate 5, the deformation part 602 can move along the clearance hole 501, and the weighing sensor 6 is arranged below the coupler 3.

[0052] In this embodiment, when the kettle body 4 is placed on the kettle base assembly, the bottom of the kettle body 4 is coupled to the coupler 3. Since the kettle body 4 and the water inside the kettle body 4 have a certain weight, a downward pressure is generated on the coupler 3. Since the weighing sensor 6 is disposed below the coupler 3, the deformation portion 602 of the weighing sensor 6 will deform as the coupler 3 moves downward. Since the support plate 5 is fixed to the lower side of the panel structure and the fixed end 601 of the weighing sensor 6 is fixed to the support plate 5, the fixed end 601 of the weighing sensor 6 remains stationary, and the deformation portion 602 of the weighing sensor 6 deforms relative to the fixed end 601. The weights of the water in the kettle body 4 are different, and the amounts of deformation of the deformation portion 602 are different. Therefore, the amount of water in the kettle body 4 can be accurately measured. Since the weight of the kettle body 4 is directly transmitted to the weighing sensor 6 and the external interference is relatively small, the measurement accuracy can be improved.

[0053] Since the coupler 3 includes a main body portion 301 and a peripheral edge 302 disposed along the circumference of the main body portion 301, the peripheral edge 302 is located above the panel structure and blocks the mounting through-hole. The peripheral edge 302 has the function of blocking water, which can prevent water from entering the interior of the kettle base assembly through the mounting through-hole and causing danger. Moreover, since the coupler 3 integrates the peripheral edge 302, compared with the related art, the number of components is reduced, and the assembly efficiency can be improved.

[0054] Specifically, as Figure 8 shown, the relief hole 501 is a rectangular hole.

[0055] In other alternative embodiments, the relief hole 501 can also be of other shapes, as long as the deformation portion 602 can pass through.

[0056] In one embodiment, the upper surface of the peripheral edge 302 is an arc surface or a conical surface, and one end of the peripheral edge 302 away from the main body portion 301 is lower than the end connected to the main body portion 301.

[0057] In this embodiment, since the upper surface of the peripheral edge 302 is an arc surface or a conical surface, and one end of the peripheral edge 302 away from the main body portion 301 is lower than the end connected to the main body portion 301, when water falls on the upper side of the peripheral edge 302, it can flow downward along the peripheral edge 302, which can prevent water from entering the interior of the kettle base assembly through the mounting through-hole and causing danger.

[0058] Specifically, as Figure 5 and Figure 6 shown, the peripheral edge 302 is in an umbrella shape.

[0059] Specifically, in one embodiment, the upper surface of the peripheral edge 302 is an arc surface or a conical surface, and the lower surface of the peripheral edge 302 is a horizontal surface. After assembly, as Figure 2 shown, there is a gap between the lower surface of the peripheral edge 302 and the upper surface of the panel structure to ensure that the coupler 3 can float up and down.

[0060] In one embodiment, the kettle base assembly further includes a fixing plate 7, which is fixed below the coupler 3 and fixedly connected to the deformation part 602.

[0061] In this embodiment, the fixing plate 7 is fixed below the coupler 3 and fixedly connected to the deformation part 602. The fixing plate 7 serves to connect the coupler 3 and the deformation part 602. Since the area of the fixing plate 7 is relatively large, it is convenient to connect both the coupler 3 and the deformation part 602.

[0062] It should be noted that in other alternative embodiments, on the premise of ensuring electrical safety, the coupler 3 can be directly fixedly connected to the deformation part 602 of the weighing sensor 6.

[0063] Specifically, in one embodiment, the fixing plate 7 is made of plastic material.

[0064] In one embodiment, the fixing plate 7 includes a mating part 703 that abuts against the deformation part 602, and a clearance part 704 that is located above the fixed end 601 and has a gap with the fixed end 601.

[0065] In this embodiment, the mating part abuts against the deformation part. When the kettle body 4 is placed on the kettle base assembly, the bottom of the kettle body 4 is coupled with the coupler 3. Since the kettle body 4 and the water in the kettle body 4 have a certain weight, it will drive the fixing plate 7 to move downward together, and drive the deformation part 602 of the weighing sensor 6 to move downward. The fixed end 601 of the weighing sensor 6 remains stationary. Since the clearance part 704 has a gap with the fixed end 601, it can ensure that the fixing plate 7 can move downward relative to the fixed end 601 of the weighing sensor 6, and the deformation part 602 of the weighing sensor 6 deforms relative to the fixed end 601, thereby achieving accurate weighing.

[0066] Specifically, in one embodiment, as Figure 3 , Figure 9 and Figure 10 shown, the deformation part 602 is provided with a first screw hole 603, the first screw hole 603 is a blind hole, and the fixing plate 7 is correspondingly provided with a first through hole 702. A screw passes through the first through hole 702 and is tightened in the first screw hole 603.

[0067] In one embodiment, a fixing post 303 is provided on the lower side of the main body part 301, and the fixing plate 7 is provided with a fixing hole 701. The fixing post 303 is fixedly connected to the fixing hole 701.

[0068] In this embodiment, by providing a fixing post 303 on the lower side of the main body part 301 and a fixing hole 701 on the fixing plate 7, and fixedly connecting the fixing post 303 to the fixing hole 701, the fixing plate 7 is fixedly connected to the coupler 3.

[0069] It should be noted that the fixing column 303 can be fixedly connected to the fixing hole 701 by interference fit, or can be fixedly connected by bonding or screws.

[0070] It should be noted that since there is a certain distance between the main body portion 301 of the coupler 3 and the fixing plate 7, a fixing column 303 is provided on the coupler, and the fixing column 303 extends downward to achieve a fixed connection with the fixing plate 7.

[0071] In one embodiment, the support plate 5 is provided with a mounting position 502, and the fixed end 601 of the weighing sensor 6 is fixed to the mounting position 502.

[0072] In this embodiment, by providing the mounting position 502 on the support plate 5, it is convenient to position and install the weighing sensor 6.

[0073] In one embodiment, a surrounding rib 503 is provided on one side of the support plate 5 facing the coupler 3. The surrounding rib 503 protrudes from the surface of the support plate 5, and the inner side of the surrounding rib 503 forms the mounting position 502.

[0074] In this embodiment, by providing the surrounding rib 503 on one side of the support plate 5 facing the coupler 3, the surrounding rib 503 protrudes from the surface of the support plate 5, and the fixed end 601 of the weighing sensor 6 is limited and fixed inside the surrounding rib 503. The surrounding rib 503 can limit the fixed end 601 of the weighing sensor 6 to prevent the position of the weighing sensor 6 from moving.

[0075] Specifically, as Figure 8 shown, the surrounding rib 503 includes a total of three rib strips, namely the first rib strip, the second rib strip and the third rib strip. The first rib strip and the third rib strip are parallel to each other, the second rib strip is connected between the first rib strip and the third rib strip, and one end of the first rib strip away from the second rib strip and one end of the third rib strip away from the second rib strip are both adjacent to the relief hole 501.

[0076] Specifically, in one embodiment, as Figure 7 、 Figure 8 and Figure 9 shown, the mounting position 502 is provided with a second through hole 504, and the fixed portion 505 of the weighing sensor 6 is provided with a second screw hole 604. The second screw hole 604 is a blind hole, and the second screw hole 604 extends upward from the lower surface of the weighing sensor 6. The screw passes through the second through hole 504 from bottom to top and is tightened in the second screw hole 604.

[0077] In one embodiment, a plurality of fixed portions 505 are provided at the edge of the support plate 5, and a plurality of connecting columns 202 protrude from the lower side of the panel structure. The connecting columns 202 are fixedly connected to the fixed portions 505.

[0078] In this embodiment, by providing a plurality of fixing portions 505 at the edge of the support plate 5 and a plurality of connecting columns 202 on the lower side of the panel structure, the connecting columns 202 are fixedly connected to the fixing portions 505, and a space sufficient to accommodate the weighing sensor 6 and the fixing plate 7 is formed between the support plate 5 and the panel structure.

[0079] Specifically, in one embodiment, as Figure 8 shown, the fixing portion 505 is a stepped hole, and the lower end of the connecting column 202 is adapted to the shape of the stepped hole.

[0080] Specifically, the connecting column 202 can be in interference fit with the stepped hole or can be fixed by gluing.

[0081] Specifically, as Figure 8 shown, the support plate 5 is a rectangular plate, and the stepped holes are provided at the four corners of the support plate 5.

[0082] In one embodiment, the panel structure includes a panel 1 and a panel bracket 2. The panel bracket 2 is supported below the panel 1. The panel 1 is provided with a first through hole 101, and the panel bracket 2 is provided with a second through hole 201. The second through hole 201 and the first through hole 101 are coaxially arranged, and the first through hole 101 and the second through hole 201 form an installation through hole.

[0083] In this embodiment, the panel structure includes a panel 1 and a panel bracket 2. The panel bracket 2 is supported below the panel 1, which can ensure that the upper surface of the kettle base assembly is flat and beautiful. The first through hole 101 and the second through hole 201 form an installation through hole, which can ensure that the coupler 3 can move up and down in the first through hole 101 and the second through hole 201.

[0084] Specifically, in one embodiment, the support plate 5 is fixedly connected to the panel bracket 2.

[0085] In one embodiment, the center of gravity line of the coupler 3 coincides with the force axis of the weighing sensor 6.

[0086] In this embodiment, by making the center of gravity line of the coupler 3 coincide with the force axis of the weighing sensor 6, the water volume in the kettle body 4 can be measured more accurately.

[0087] Specifically, in one embodiment, the kettle base assembly further includes a base 8. The base 8 and the panel bracket 2 enclose an installation space, and the support plate 5 is located in the installation space. Wires, upper water pipelines, etc. are also provided in the installation space.

[0088] When the kettle base assembly provided in this embodiment is installed, first fixedly connect the fixed end 601 of the weighing sensor 6 to the support plate 5, then fixedly connect the fixing plate 7 to the deformation part 602 of the weighing sensor 6, fixedly connect the fixing plate 7 to the coupler 3, and finally fixedly connect the support plate 5 to the panel bracket 2. After the coupler 3 is fixed, there is a certain gap between the peripheral edge 302 of the coupler 3 and the panel 1, ensuring that the coupler 3 can be floatingly arranged on the weighing sensor 6.

[0089] According to an embodiment of the present invention, on the other hand, an electric kettle is further provided, including: a kettle body 4 and the kettle base assembly provided in the above embodiment.

[0090] For this electric kettle, when the kettle body 4 is placed on the kettle base assembly, the bottom of the kettle body 4 is coupled to the coupler 3. Since the kettle body 4 and the water in the kettle body 4 have a certain weight, a downward pressure will be generated on the coupler 3. Since the weighing sensor 6 is arranged below the coupler 3, the deformation part 602 of the weighing sensor 6 will deform as the coupler 3 moves downward. Since the support plate 5 is fixed to the lower side of the panel structure and the fixed end 601 of the weighing sensor 6 is fixed to the support plate 5, the fixed end 601 of the weighing sensor 6 remains stationary, and the deformation part 602 of the weighing sensor 6 deforms relative to the fixed end 601. The weight of the water in the kettle body 4 is different, and the amount of deformation of the deformation part 602 is different. Therefore, the amount of water in the kettle body 4 can be accurately measured. Since the weight of the kettle body 4 is directly transmitted to the weighing sensor 6 and the external interference received is relatively small, the measurement accuracy can be improved. Since the coupler 3 includes a main body part 301 and a peripheral edge 302 arranged along the circumference of the main body part 301, the peripheral edge 302 is located above the panel structure and blocks the installation through hole, and the peripheral edge 302 has the function of blocking water, which can prevent water from entering the inside of the kettle base assembly through the installation through hole and causing danger. Moreover, since the coupler 3 integrates the peripheral edge 302, compared with the related art, the number of parts is reduced, and the assembly efficiency can be improved.

[0091] Specifically, in an embodiment, the electric kettle further includes a water supply assembly and a controller. When the amount of water in the kettle body 4 increases, gravity acts on the coupler 3, and the deformation part 602 of the weighing sensor 6 is deformed more by the force. When the amount of water in the kettle body 4 decreases, the deformation of the deformation part 602 of the weighing sensor 6 decreases. The amount of deformation of the weighing sensor 6 is transmitted to the controller, and the controller controls the water supply assembly to add water to the kettle body 4 or stop adding water according to the set value.

[0092] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
