Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric kettle technology, and in particular to a direct-heating kettle that prevents tipping. Background Technology
[0002] In recent years, electric kettles, as common small household appliances, have mostly adopted induction heating. This method indirectly heats the bottom of the kettle body through the principle of electromagnetic field coupling. Although it has advantages such as low risk of electric leakage and high energy utilization, it is more expensive and has limited heating efficiency. To improve heating speed and reduce costs, direct heating kettles have gradually become an important choice in the market. Direct heating directly heats the water inside the kettle through an electric heating element. Compared with induction heating, it has a significant cost advantage and can heat water in a shorter time, thus meeting consumers' demand for rapid heating. However, existing direct heating electric kettles still face certain safety hazards during use, especially when the kettle is tilted, the water inside may overflow due to improper operation, posing a risk of scalding to users.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0020] like Figure 1-6As shown, an anti-tipping direct-heating kettle includes a lid assembly 1 and a kettle body 2. A first cavity wall 24 and a second cavity wall 25 are fixedly disposed inside the kettle body 2, dividing the inner cavity of the kettle body 2 into a first inner cavity 21, a second inner cavity 22, and a third inner cavity 23. A direct-heating assembly 4 is fixed in the second inner cavity 22, and the heating element 41 of the direct-heating assembly 4 is located in the first inner cavity 21. A sealing ring 42 is fixed between the heating element 21 and the first cavity wall 24. The lid assembly 1 is flush with the upper edge of the kettle body 2 by a countersunk lid assembly. The lid assembly 1 includes a lid 11 and a lid seat 12. The lid seat 12 is located... The lid seat 12 is sealed to the body 2. A spout 13 is provided on the side wall of the lid seat 12, and a through hole 14 is provided at the bottom of the lid seat 12, connecting the spout 13 and the first inner cavity 21. A locking assembly is provided between the lid assembly 1 and the body 2. The locking assembly includes two locking tongues 32 connected by a locking spring 31. The inner side of the lid seat 12 has symmetrical first locking grooves 33, and the inner side of the body 2 has symmetrical second locking grooves 34. An upward protrusion 35 is integrally provided on each of the two locking tongues 32, protruding from the lid 11, and the locking tongues 32 pass through the corresponding first locking grooves 34. The locking groove 33 is inserted into the second locking groove 34, locking the lid assembly 1 to the body 2. When the two protrusions 35 are pressed, the locking tongues 32 disengage from the second locking grooves 34 one by one, unlocking the lid assembly 1 from the body 2. The lid assembly 1 is provided with a first anti-overflow device to prevent water in the first inner cavity 21 from accidentally flowing out of the water outlet 13 of the lid seat 12. The first anti-overflow device includes a water sealing rod 51, a first spring 52, and a second spring 53. The water sealing rod 51 is rotatably connected to the lid seat 12, and the front end of the water sealing rod 51 is engaged with a water outlet rod 54. The lower end of the water outlet rod 54 is fixed. A sealing gasket 55 is fixed, and the sealing gasket 55 is opposite to the through hole 14. The first spring 52 is pressed between the lower end of the lid seat 12 and the water outlet rod 54. One end of the second spring 53 is fixed to the inner bottom surface of the lid seat 12, and the other end is fixed to the lower surface of the water sealing rod 51. The rear end of the water sealing rod 51 extends out of the lid 11. When the water sealing rod 51 is pressed manually, the water outlet rod 54 is lifted, and the water in the first inner cavity 21 can flow out. When the water sealing rod 51 is released, under the action of the first spring 52 and the second spring 53, the sealing gasket 55 presses the through hole 14 tightly, so that even if the kettle body 2 is tilted, the water in the kettle body 2 will not flow out from the water outlet 13.A second anti-overflow device is provided in the third inner cavity 23 to prevent water in the first inner cavity 21 from accidentally flowing out of the steam outlet 26 of the kettle body 2. A steam vent 251 and a steam guide 252 are provided on the second cavity wall 25. The steam vent 251 connects the first inner cavity 21 and the third inner cavity 23, and the steam guide 252 connects the second inner cavity 22 and the third inner cavity 23. The second anti-overflow device includes a steam guide tee 61. The first interface 611 of the steam guide tee 61 is connected to the steam outlet 26, the second interface 612 of the steam guide tee 61 is connected to the steam guide 252, and the third interface 613 of the steam guide tee 61 is connected to the steam vent 251. Multiple guide ribs 62 are integrally provided along the circumferential direction on the inner surface of the steam vent 251. A movable gravity valve is provided inside the steam vent 251. When the kettle body 2 tilts, the gravity block 63 moves towards the steam outlet 26 under the guidance of the guide rib 62, blocking the third interface 613 to prevent water in the first inner cavity 21 from flowing into the steam guide tee 61 from the steam vent 251. During the boiling process, the gravity block 63 is located inside the steam vent 251, and there is a gap between the gravity block 63 and the inner wall of the steam vent 251. Steam in the first inner cavity 21 enters the steam guide tee 61 through the steam vent 251, the gap, and the third interface 613. Part of the steam is discharged from the first interface 611 and the steam outlet 26 to the outside of the kettle body 2, preventing excessive steam pressure in the first inner cavity 21. The other part of the steam enters the second inner cavity 22 from the second interface 612. The temperature control switch in the direct heating assembly controls the power off by sensing the steam temperature.
[0021] In this embodiment, the direct heating component is a built-in part of an existing direct heating kettle.
