Description

Technical Field

[0001] This utility model relates to the field of electric kettle technology, and in particular to a noise-reducing electric kettle. Background Technology

[0002] The noise generated by an electric kettle during the boiling process is parabolic. Most electric kettles on the market produce a volume of 75 decibels, with the peak noise level mostly around 60 degrees Celsius, which is noticeable to users.

[0003] In related technologies, the pre-pressed heating element in the base of an electric kettle is crescent-shaped. This causes high-noise bubbles to form on the bottom of the kettle during the heating process, resulting in significant noise and greatly affecting the user experience. Utility Model Content

[0004] The main purpose of this utility model is to propose a noise-reducing electric kettle, which aims to reduce the noise of the electric kettle during operation and improve the user experience.

[0005] To achieve the above objectives, the present invention proposes a noise-reducing electric kettle, comprising:

[0006] The pot body includes the pot body and the pot bottom;

[0007] A base plate that fits against the bottom surface of the teapot, away from the body of the teapot;

[0008] The base is equipped with heating elements that are evenly distributed throughout the base. The thickness of the kettle body is 1.2-2.5 mm, and the thickness of the kettle bottom is 1.2-2.5 mm.

[0009] In one embodiment, the heating element is strip-shaped and the heating elements are evenly distributed in a spiral shape on the chassis.

[0010] In one embodiment, the chassis includes an aluminum cladding that covers the heating element and is connected to the bottom of the kettle.

[0011] In one embodiment, the chassis includes wiring pins that pass through the aluminum cladding and are connected to the heating element.

[0012] In one embodiment, the chassis includes an aluminum sheet layer, which is disposed between the chassis and the bottom of the kettle.

[0013] In one embodiment, the chassis is provided with a through hole, and the through hole penetrates the aluminum sheet layer.

[0014] In one embodiment, a temperature sensing element is provided inside the through hole to monitor the internal temperature of the kettle body.

[0015] In one embodiment, the chassis further includes a metal layer, which is disposed between the aluminum sheet layer and the bottom of the pot, and the metal layer seals one opening of the through hole.

[0016] In one embodiment, the thickness of the metal layer ranges from 1.2 to 2.5 millimeters.

[0017] In one embodiment, the bottom surface of the pot is arc-shaped, and the side of the base connecting to the bottom of the pot is arc-shaped.

[0018] The technical solution of this utility model is to evenly distribute the heating element in the base, so that when the heating element is working, it heats the bottom of the pot evenly, improving the heat transfer efficiency and further reducing the noise generated by vibration during the heat transfer process. Moreover, when the bottom of the pot is heated and transfers heat to the liquid, bubbles are generated all over the surface of the pot, thereby dispersing the bubbles and reducing the generation of bubbles, reducing the noise after the bubbles burst. At the same time, the pot body and the bottom of the pot are thickened to weaken vibration and further reduce noise. Attached Figure Description

[0028] The noise generated by an electric kettle during the boiling process is parabolic. Most electric kettles on the market produce a volume of 75 decibels, with the peak noise level mostly around 60 degrees Celsius, which is noticeable to users.

[0029] In related technologies, the pre-pressed heating element in the base of an electric kettle is crescent-shaped. This causes high-noise bubbles to form on the bottom of the kettle during the heating process, resulting in significant noise and greatly affecting the user experience.

[0030] Therefore, this utility model proposes a noise-reducing electric kettle.

[0031] Please see Figure 1 In one embodiment of this utility model, the noise-reducing electric kettle includes:

[0032] The pot body 10 includes a pot body 11 and a pot bottom 12;

[0033] The base 40 is attached to the bottom surface of the pot bottom 12, which is opposite to the bottom surface of the pot body 11;

[0034] The base 40 is equipped with heating elements 50, which are evenly distributed throughout the base 40. The thickness of the body 11 is 1.2-2.5 mm, and the thickness of the bottom 12 is 1.2-2.5 mm.

[0035] It is understandable that both the body 11 and the bottom 12 of the kettle are thickened. By thickening the body 10, the rolling bubbles are prevented from hitting the body 11 and generating more noise when the kettle is filled with water and heated, thus improving the user experience.

[0036] It is understandable that by thickening the bottom 12 of the kettle, when the base 40 transfers heat to the kettle body 10, the thickened bottom 12 generates bubbles. The generated bubbles will not burst or suddenly explode, thus avoiding greater noise.

[0037] like Figure 1 and Figure 2 As shown, the base 40 is disposed on the bottom 12 of the kettle, so as to facilitate the output of heat from the base 40 to the kettle body 10 to achieve electric heating.

[0038] It is understood that the body 11 and the bottom 12 are integrally formed, and the base 40 is located on the bottom surface of the bottom 12. The integrally formed body 10 avoids the liquid-containing cavity being formed by splicing, and the base 40 is directly heated to the metal bottom, ensuring heat conduction efficiency.

[0039] In one embodiment, the body 11 is an exposed bottom type, and the bottom 12 is disposed on the surface of the base 40. When the bottom 12 is installed with the body 11, the bottom 12 wraps around the bottom of the body 11 and is fixedly connected to the bottom 12. Thus, the body 11 and the bottom 12 together form a container for holding liquid, which is convenient for receiving liquid. Moreover, the body 11 and the bottom 12 are designed separately, which reduces the production difficulty of the body 10.

[0040] The technical solution of this utility model is to evenly distribute the heating element 50 within the base 40, so that when the heating element 50 is working, it evenly heats the bottom 12 of the pot, improving heat transfer efficiency and further reducing the noise generated by vibration during heat transfer. Moreover, when the bottom 12 of the pot is heated and transfers heat to the liquid, bubbles are generated all over the surface of the pot body 10, thereby dispersing the bubbles and reducing their generation, and reducing the noise after the bubbles burst. At the same time, the pot body 11 and the bottom 12 of the pot are thickened to weaken vibration and further reduce noise.

[0041] In one embodiment, the heating element 50 is strip-shaped and is evenly distributed in a spiral shape on the chassis 40.

[0042] It is understood that the heating element 50 is strip-shaped and spirally distributed inside the chassis 40, that is, the heating element 50 is distributed in a mosquito coil shape. When the heating element 50 is working, the heating element 50 evenly distributed in the chassis 40 makes the surface of the chassis 40 connected to the bottom of the pot 12 evenly heated, and evenly transfers heat to the surface of the bottom of the pot 12, thereby improving the heat transfer efficiency and reducing the noise generated by vibration during the heat transfer process.

[0043] In another embodiment, the heating element 50 is arranged in multiple bends, and the spacing between the multiple heating elements 50 is equal, so that the heating elements 50 can be evenly distributed on the chassis 40, so that the chassis 40 can conduct heat evenly.

[0044] In one embodiment, the chassis 40 includes an aluminum cladding that covers the heating element 50 and is connected to the bottom of the kettle 12.

[0045] It is understood that the aluminum cladding is wrapped around the heating element to protect it.

[0046] Furthermore, in order to ensure the heat transfer efficiency between the chassis 40 and the kettle bottom 12, the chassis 40 and the kettle bottom 12 need to be fitted together so that the aluminum cladding is completely fitted to the kettle bottom 12, and the surface shape of the aluminum cladding facing the kettle bottom 12 is adapted to the kettle bottom 12.

[0047] In one embodiment, the chassis 40 includes wiring pins that pass through the aluminum cladding and are connected to the heating element 50.

[0048] It is understood that, in order to facilitate the control and power supply of the heating element 50, the wiring pin is inserted into the aluminum cladding. One end of the wiring pin extends into the aluminum cladding and is connected to the heating element 50, while the other end of the wiring pin is located outside the aluminum cladding to facilitate connection to external circuitry.

[0049] In one embodiment, the chassis 40 includes an aluminum sheet layer 30, which is disposed between the chassis 40 and the bottom of the pot 12.

[0050] It is understood that the aluminum sheet layer 30 is provided between the chassis 40 and the bottom of the kettle 12. When the heating element 50 works and the chassis 40 is heated evenly, heat can be evenly conducted to the bottom of the kettle 12 through the aluminum sheet layer 30, and the heat conduction efficiency is guaranteed.

[0051] Furthermore, when the kettle bottom 12 is connected to the chassis 40, the aluminum sheet layer 30 is provided between the kettle bottom 12 and the chassis 40. Thus, when the kettle bottom 12 and the chassis 40 are connected by welding or other means, the aluminum sheet layer 30 can assist in the connection and improve the stability of the connection between the kettle bottom 12 and the chassis 40.

[0052] In one embodiment, the chassis 40 is provided with a through hole 60, and the through hole 60 penetrates the aluminum sheet layer 30.

[0053] like Figure 2 As shown, the through hole 60 is located at the center of the chassis 40 and penetrates the chassis 40. The heating element 50 is coiled around the through hole 60.

[0054] It is understandable that, since the through hole 60 is provided in the middle of the base 40, during the process of the heating element 50 working and transferring heat to the kettle body 10, the kettle body 10 and the base 40 vibrate due to the airflow. With the cooperation of the through hole 60, the resulting resonance can cause the bottom of the kettle to be fully dispersed to generate low-noise bubbles, thereby reducing the noise generated by the bursting of bubbles.

[0055] In one embodiment, a temperature sensing element is provided inside the through hole 60 to monitor the internal temperature of the kettle body 10.

[0056] It should be noted that the operation of the heating element 50 will cause the liquid in the kettle body 10 to boil. If the heating element 50 continues to operate when the liquid is boiling, it may cause the kettle body 10 to operate and cause danger.

[0057] It is understood that the temperature sensing element is provided in the through hole 60. When the base 40 is connected to the bottom 12 of the kettle, the bottom 12 of the kettle is blocked in one opening of the through hole 60. At this time, the temperature sensing element is used to sense the temperature change inside the kettle body 10. When the liquid inside the kettle body 10 boils, after the temperature sensing element senses the specific temperature, the temperature sensing element sends a signal to control the heating element 50 to stop working, so as to avoid continuous heating and affect the safety of the kettle body 10 operation.

[0058] Furthermore, in order to facilitate the control of the operation of the heating element 50, a control unit is provided in the chassis 40, and the control unit is electrically connected to the heating element 50 and communicatively connected to the temperature sensing unit.

[0059] It is understandable that after receiving the signal from the temperature sensing unit, the control unit controls the heating element 50 to stop operating, thereby ending the heating of the kettle body 10.

[0060] In one embodiment, the chassis 40 further includes a metal layer 70, which is disposed between the aluminum sheet layer 30 and the bottom of the pot 12, and the metal layer 70 seals one opening of the through hole 60.

[0061] It is understandable that when the pot body 10 is a bottomless pot body, the metal layer 70 is bent and wrapped around the pot body to form a cavity for containing liquid.

[0062] It is understood that the metal layer 70 and the aluminum sheet layer 30 are disposed between the kettle body 10 and the base 40. The metal layer 70 serves as the bottom of the kettle, and the aluminum sheet layer 30 is used to achieve stable heat transfer, thereby ensuring that the kettle body 10 is heated evenly and reducing the noise generated by vibration during heat transfer.

[0063] In one embodiment, the thickness of the metal layer 70 ranges from 1.2 to 2.5 millimeters.

[0064] In one embodiment, the bottom surface of the pot bottom 12 is arc-shaped, and the side of the base 40 connected to the pot bottom 12 is arc-shaped.

[0065] It should be noted that, in order to ensure the efficiency and uniformity of heat transfer between the pot bottom 12 and the base plate 40, the pot bottom 12 and the base plate 40 are adapted to each other.

[0066] It is understood that if the bottom surface of the pot bottom 12 is flat, then the side of the base 40 facing the pot bottom 12 is also flat. By increasing the contact area with the pot bottom 12, the efficiency of heat transfer is ensured.

[0067] In another embodiment, the bottom 12 of the pot is curved, and the base 40 is curved, so that the bottom 12 of the pot and the base 40 fit together. Since both the bottom 12 of the pot and the base 40 are curved, the bottom 12 of the pot and the base 40 are prevented from moving relative to each other, thus ensuring that the bottom 12 of the pot and the base 40 are in close contact.

[0068] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
