Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an electric kettle that prevents overflow when tilted. Background Technology

[0002] Electric kettles, with their advantages of boiling water quickly, ease of use, and portability, have become an indispensable appliance in people's lives. There are several ways for electric kettles to automatically shut off, among which steam shut-off is a common method. Electric kettles include a steam channel. When the water inside the kettle boils, a large amount of steam is generated. Due to the pressure difference between the kettle's internal environment and atmospheric pressure, the steam is forced into the steam channel. The bottom of the steam channel is aligned with a temperature sensing component. When the temperature-sensing metal spring on the thermostat senses that the steam temperature has reached a preset value, such as 100℃, the metal spring deforms due to the heat, thereby triggering the power switch and achieving automatic power-off.

[0003] However, in actual use, the above-mentioned steam-power-off electric kettle has the following shortcomings: First, when the water in the kettle boils, the boiling water will enter the steam channel and flow along the steam channel to the temperature sensing component, which will affect the temperature sensing metal spring's judgment of the water temperature in the kettle and cause abnormal tripping; Second, if the kettle is accidentally tipped over, the water in the kettle will flow along the steam channel to the temperature sensing component at the bottom of the kettle, thereby damaging the temperature sensing component and the electronic control component, or even overflowing from the bottom of the kettle, causing a short circuit in the kettle circuit and causing a safety accident. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an electric kettle that can prevent water from entering the steam channel, especially an electric kettle that can prevent water from overflowing when tilted, in view of the above-mentioned existing technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problem is: an electric kettle that prevents overflow when tilted, comprising:

[0006] The kettle body has a water-holding cavity inside.

[0007] The temperature sensing component is located inside the kettle body and is isolated from the water-filling cavity;

[0008] Its characteristic is that it further includes:

[0009] A steam pipe is provided inside the kettle body, comprising a first pipe section extending horizontally and a second pipe section extending downward. The first pipe section and the second pipe section are connected to each other by a bent connecting end. The first pipe section is arranged along the top of the water-filling cavity, and the end of the first pipe section is an inlet end for steam to enter. The bottom end of the second pipe section faces the temperature sensing component and serves as an outlet end for guiding steam to the temperature sensing component.

[0010] Furthermore, in the first pipe section, the height of the inlet end relative to the bottom of the kettle body is lower than the height of the connecting end relative to the bottom of the kettle body.

[0011] As a preferred structure for the first pipe section, the kettle body is cylindrical, and the first pipe section is C-shaped, extending around the inner wall of the water-holding cavity, gradually rising from the inlet end to the connection end. The C-shaped first pipe section extending along the inner wall of the water-holding cavity prevents water from entering the first pipe section from the inlet end when the kettle is tilted, and prevents water from flowing along the steam pipe towards the temperature-sensing component and damaging the temperature-sensing and electronic control components. Designing the first pipe section to gradually rise from the inlet end also allows water to flow downwards along the first pipe section and out from the inlet end if water accidentally enters the first pipe section, effectively preventing water from overflowing from the bottom of the kettle.

[0012] To effectively prevent water from flowing along the steam pipe to the temperature sensing component when the kettle is tilted, preferably, the central angle of the first C-shaped pipe segment is 120° to 360°. If the central angle of the first pipe segment is too small, when the kettle is tilted sideways towards the first pipe segment, as long as the water level is higher than the inlet end, the water can still enter from the inlet end and flow to the second pipe segment and be guided to the temperature sensing component. Therefore, by setting the central angle of the first pipe segment to 120° to 360°, the inlet end is positioned at the top of the tilted kettle body, i.e., above the liquid level inside the kettle, preventing water from entering the inlet end.

[0013] To enable the steam pipe to guide steam from the water chamber to the temperature-sensing component, which is isolated from the water chamber, preferably, a partition is provided inside the kettle body, dividing the interior into an upper water chamber and a lower electrical control area, where the temperature-sensing component is located; the second pipe section extends downward through the partition. Thus, the outlet end of the second pipe section is located below the partition, allowing steam to flow along the second pipe section towards the electrical control area below the partition and approach the temperature-sensing component.

[0014] To facilitate the installation of the steam pipe, preferably, the kettle body also has an installation area for installing the first pipe section. This installation area is surrounded by the inner wall of the water-containing cavity, a first wall portion parallel to the inner wall, and a second wall portion connecting the inner wall and the first wall portion. The installation area is located at the top of the water-containing cavity and has a lower opening communicating with the water-containing cavity. The first pipe section is installed within this installation area, preventing the steam pipe from being directly exposed. Since the installation area communicates with the water-containing cavity, steam can enter the installation area from the water-containing cavity through the lower opening, then enter the steam pipe from the inlet end and be guided to the temperature-sensing component.

[0015] Preferably, the lower end of the first wall portion has a curved section that bends inward into the mounting area. This curved section creates a rounded transition at the lower end of the first wall portion, preventing scratches from the edge of the first wall portion when cleaning the electric kettle.

[0016] Compared with the prior art, the advantages of this utility model are as follows: the steam pipe of the electric kettle is composed of a first pipe section extending horizontally and a second pipe section extending downward. The first pipe section is set along the top of the water-filling cavity, and the height of the inlet end relative to the bottom of the kettle body is lower than the height of the connecting end relative to the bottom of the kettle body. This can effectively prevent water from entering the steam pipe and being guided to the temperature sensing component when the kettle is tilted or when the water boils. Even if some water enters from the steam pipe, it can flow out from the inlet end because the height of the inlet end is lower than that of the connecting end. This design can improve the safety of using the electric kettle. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1-6 The image shown is a preferred embodiment of the present invention.

[0025] See Figure 1-2 The electric kettle of this embodiment includes a kettle body 1, a spout 13 and a handle 14 disposed outside the kettle body 1. The kettle body 1 has a water-holding cavity 11 and a temperature-sensing component 3 isolated from the water-holding cavity 11. The kettle body 1 also has a steam pipe 4 that guides steam from the water-holding cavity 11 to the temperature-sensing component 3. A kettle lid 15 is disposed on the top of the kettle body 1 to cover the upper opening of the cavity 11. When the electric kettle boils water, a large amount of steam is generated after the water boils. Due to the pressure difference between the internal environment of the kettle body 1 and atmospheric pressure, the steam is squeezed into the steam pipe 4 and guided to the temperature-sensing component 3. When the temperature-sensing component 3 senses that the steam temperature has reached the preset temperature, it can trigger the power switch to automatically cut off the power.

[0026] To prevent water from entering through the steam pipe 4 and being guided to the temperature sensing component 3 when the kettle body 1 is tilted or when the water is boiling, thus avoiding circuit malfunction, this embodiment has made special improvements to the steam pipe 4. See details below. Figure 3-4 In this embodiment, the steam pipe 4 includes a generally horizontally extending first pipe section 41 and a downwardly extending second pipe section 42, which are connected to each other by a bent connecting end 41b. The first pipe section 41 is disposed along the top of the water-filled cavity 11, and the end of the first pipe section 41 is an inlet end 41a for steam to enter. The height of the inlet end 41a relative to the bottom of the kettle body 1 is lower than the height of the connecting end 41b relative to the bottom of the kettle body 1. The bottom end of the second pipe section 42 faces the temperature sensing component 3 and serves as the outlet end 42a for guiding steam to the temperature sensing component 3.

[0027] Specifically, the first pipe segment 41 is designed to be C-shaped, extending around the inner wall 1a of the water-holding cavity 11, and gradually rising from the inlet end to the connection end. If the central angle corresponding to the first pipe segment 41 is too small, the water will flow directly into the steam pipe 4 and overflow from the steam pipe 4 after the kettle body 1 is tilted. In order to effectively prevent water from overflowing from the steam pipe 4 when the kettle body 1 is tilted, the design of the steam pipe needs to meet the requirement that the amount of water overflowing within 3 seconds after the kettle body 1 is tilted is less than 50ml. Therefore, in this embodiment, the angle of the central angle corresponding to the first pipe segment 41 is designed to be 120° to 360°.

[0028] To improve the overflow prevention effect of the steam pipe 4, the central angle corresponding to the first pipe section 41 is preferably 240° to 310°, such as 260°, 280°, 300°, or other suitable angles. When the kettle body 1 is tilted, due to the design of the spout 13, the kettle body 1 will rotate towards the spout 13 and be limited by the spout 13 after being tilted in any direction. Therefore, after the kettle body 1 is tilted, only the steam pipe 4 is left unloaded. Figure 5 and Figure 6 The two states are shown. If pot 1 tilts to... Figure 5 In the shown state, since the central angle corresponding to the first pipe section 41 is 240°~310°, its inlet end 41a is at the top of the tilted kettle body 1, while the water inside the kettle is concentrated at the bottom of the kettle body 1, thus preventing water from entering from the inlet end 41a. It is worth noting that the water-holding cavity 11 should be set to the highest water level to avoid overfilling the water-holding cavity 11. If the electric kettle is tilted backwards to... Figure 6In the indicated state, the inlet end 41a of the first pipe section 41 is located at the bottom of the tilted kettle body 1. The water level in the kettle is at risk of submerging the inlet end 41a and entering the first pipe section 41. In this state, due to the "C"-shaped design of the first pipe section 41 and the angle of its central angle of 240° to 310°, at least part of the first pipe section 41 is located at the top of the kettle body 1. Water cannot flow upward along the first pipe section 41, passing over the part of the first pipe section 41 located at the top of the kettle body 1 and flowing to the second pipe section 42. This prevents the water in the kettle from being guided to the temperature sensing component 3 when the kettle body 1 is tilted. After the kettle body 1 is uprighted, as the height from the inlet end 41a to the connecting end 41b gradually increases, the water entering the first pipe section 41 will flow downward under the action of gravity and flow out from the inlet end 41a.

[0029] In addition, the design that the height of the inlet end 41a relative to the bottom of the kettle body 1 is lower than the height of the connection end 41b relative to the bottom of the kettle body 1 can also prevent water from entering the steam pipe 4 when boiling and rolling and being guided to the temperature sensing component 3, thus avoiding damage to the temperature sensing component 3 and the electronic control component.

[0030] To isolate the temperature sensing component 3 from the water-filling chamber 11, this embodiment includes a partition 2 inside the kettle body 1. The partition 2 divides the interior of the kettle body 1 into the upper water-filling chamber 11 and the lower electrical control area 12, where the temperature sensing component 3 is located. The second pipe section 42 extends downward through the partition 2, with its outlet end 42a located below the partition, thereby guiding steam to the electrical control area below the partition 2 and closer to the temperature sensing component 3. To prevent water in the water-filling chamber 11 from flowing into the electrical control area 12 through the gap between the second pipe section 42 and the partition 2, this embodiment welds the outer wall of the second pipe section 42 to the partition 2.

[0031] Figure 2 This is a longitudinal sectional view of the electric kettle in this embodiment. The top of the water-filling cavity 11 has a mounting area 5 for installing the first pipe section 41. The mounting area 5 is surrounded by the inner wall 1a of the water-filling cavity 11, a first wall portion 5a parallel to the inner wall 1a, and a second wall portion 5b connecting the inner wall 1a and the first wall portion 5a. It also has a lower opening communicating with the water-filling cavity 11. Steam can enter the mounting area 5 from the water-filling cavity 11 through the lower opening and then enter the steam pipe 4 through the inlet end 41a. The mounting area 5 prevents the steam pipe 4 from being directly exposed. To prevent the lower edge of the first wall portion 5a from scratching the user, the lower end of the first wall portion 5a has a curved section 5c that bends inward into the mounting area 5, making the lower end of the first wall portion 5a rounded.
