Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to an electric kettle. Background Art

[0002] The basic structure of electric kettles currently on the market is a water tank and a heating device installed within a shell. The heating device heats the water in the tank, and the water outlet on the shell is connected to the water tank via a water pipe, allowing users to collect water through the outlet. With the popularization of intelligent technology, kettles are now often equipped with cameras. The controller can be set to enable the camera to detect when the water cup is full and automatically stop the water supply, thus improving the user experience.

[0003] However, when hot water is discharged from the water outlet, it is usually accompanied by water vapor. The water vapor adheres to the lens of the camera to form a layer of water mist, making the image taken by the camera blurry and causing the camera-based automatic water stop function when the cup is full to fail. The commonly used solution at present is to heat the camera lens to defog. The specific settings include adding a heating element and connecting a heat conductor from the heating device for heating the water tank to the camera for heating and defog. The former solution requires an additional heating element, which increases the overall cost of the electric kettle. Although the latter solution utilizes the heat of the heating device, the heating device of the electric kettle usually stops working after boiling the water in the water tank during actual use. Even if the heating device may be started for reheating later, the heating device is not always in working state. When the user collects water when the heating device is not in working state, the water outlet directly discharges the water in the water tank. The discharged water at this time may be hot water with water vapor and higher temperature, or it may be cold water without water vapor and lower temperature. When the user collects hot water with water vapor, the camera cannot obtain heat from the heating device through the heat conductor, that is, it cannot heat and defog the camera, and cannot ensure the normal operation of the full cup automatic water stop function. Summary of the Invention

[0004] The present application aims to improve the problems existing in the above-mentioned prior art. That is, the purpose of the present application is to provide an electric kettle, which can transfer the heat of the water tank to the camera through the heat-conducting component, without being limited by whether the heating device is in a working state. When there is hot water in the water tank, the camera is always heated. When the water outlet discharges hot water, the camera can always be adaptively heated to defog to improve the image clarity of the camera.

[0005] The present application provides an electric kettle, comprising a shell, a water tank arranged inside the shell, and a heating device. The shell is provided with a water outlet and a camera. The water outlet is connected to the water tank through a water outlet pipe. The water tank and the camera are connected through a heat-conducting component. The heat-conducting component is used to conduct heat from the water tank to the camera, so that when hot water is discharged from the water outlet, the heat-conducting component adaptively heats the camera to defog.

[0006] In one embodiment, the heat-conducting component includes a first connecting portion and a second connecting portion, the first connecting portion is disposed against the outer wall of the water tank, and the second connecting portion is disposed against the outer wall of the camera.

[0007] In one embodiment, the heat conducting component includes a first connecting portion, the first connecting portion is spirally wound around the side wall of the water tank, and / or the first connecting portion is coiled and abuts against the bottom wall of the water tank.

[0008] In one embodiment, the side wall and / or bottom wall of the water tank is provided with an inner recessed portion having a winding shape matching the first connecting portion, the first connecting portion is arranged correspondingly against the inner recessed portion, and a thermal conductive paste is provided on the side of the first connecting portion facing away from the water tank, and the thermal conductive paste is connected to the outer wall of the water tank.

[0010] In one embodiment, the main body section extends in a vertical direction, and the lead-out section extends in a horizontal direction, so as to reduce the length of the conducting portion.

[0012] In one embodiment, the camera includes an annular lens holder and a lens disposed in the lens holder, and the second connecting portion is spirally wound around an outer wall of the lens holder.

[0013] In one embodiment, a fan is provided on the outer shell, a temperature sensor is provided at the water outlet, and a controller is provided in the outer shell. The fan and the temperature sensor are electrically connected to the controller. The controller is used to control the start and stop of the fan based on the real-time temperature value of the temperature sensor to remove water vapor.

[0014] In one embodiment, a fan is provided on the casing, and an electrothermal conversion device is provided at the water outlet. The electrothermal conversion device is electrically connected to the fan. The electrothermal conversion device is used to convert the thermal energy of hot water into electrical energy to power the fan, so that the fan operates adaptively to remove water vapor.

[0015] Beneficial effects:

[0016] In the present invention, a heat transfer component directly connects the water tank to the camera. As long as the water in the water tank is hot, the hot water transfers heat to the water tank. This heat is then transferred to the camera through the heat transfer component, ensuring that the camera is always heated. This prevents fogging of the camera lens whenever the user connects to the water outlet, allowing for clear images and ensuring the proper functioning of camera-dependent features, such as the camera's full-cup water shut-off feature. By directly linking camera heating to the water temperature in the water tank, the present invention eliminates the need for a dedicated camera heating device, nor does it require a matching water temperature detection device or water vapor / mist detection device to determine whether the defogger function should be activated. This simple configuration of the heat transfer component eliminates the need for the camera to determine whether the defogger function should be activated based on the current water supply conditions. The camera is then adaptively heated, ensuring that the heated defogging of the camera lens is always effective when hot water is supplied, thereby ensuring the reliability of the full-cup water shut-off feature and significantly reducing equipment costs.

[0017] In one embodiment of the present invention, the heat-conducting component is arranged in contact with the outer wall of the water tank through the first connecting part, and is arranged in contact with the camera through the second connecting part. The water tank and the camera do not need to be provided with an assembly structure specifically for connecting with the heat-conducting component. The installation is simple and the production cost is reduced. The contact setting can also improve the heat conduction efficiency between the heat-conducting component and the water tank and the camera.

[0018] In one embodiment of the present invention, the first connecting portion of the heat conducting component is spirally wound around the side wall of the water tank, and / or the first connecting portion is coiled and abutted against the bottom wall of the water tank, thereby increasing the contact area and reliability between the second connecting portion and the camera, avoiding separation between the two, and ensuring the heat conducting effect.

[0020] In one embodiment of the present invention, the camera includes an annular lens holder and a lens disposed in the lens holder, and the second connecting portion is spirally disposed around the outer wall of the lens holder to increase the contact area between the second connecting portion and the lens holder, thereby improving the heat conduction efficiency and improving the connection reliability between the heat conduction component and the camera.

DETAILED DESCRIPTION

[0031] The following specific embodiments are merely explanations of the present application and are not limitations of the present application. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present application, they are protected by the patent law.

[0032] Reference Figure 1 As shown, the present application discloses an electric kettle, comprising a shell 100, a water tank 200 and a heating device 300 arranged in the shell 100, the shell 100 is provided with a water outlet 110 and a camera 120, the water outlet 110 is connected to the water tank 200 through a water outlet pipe 400, the water tank 200 and the camera 120 are connected through a heat conducting component 500, the heat conducting component 500 is used to conduct the heat of the water tank 200 to the camera 120, so that when the water outlet 110 discharges hot water, the heat conducting component 500 adaptively heats the camera 120 to defog, so that the camera 120 can capture a clear image, ensuring the normal operation of the special functions that rely on the camera 120, such as the liquid level detection of the water cup based on the camera 120 to realize the automatic water stop function when the cup is full. In the electric kettle provided by the present application, the heating device 300 transfers heat to the water contained in the water tank 200 by heating the water tank 200. The water tank 200 itself is a good heat conductor. Therefore, when the heating device 300 is in an inoperative state, if the water tank 200 contains hot water, the hot water will transfer heat to the water tank 200. The temperature of the water tank 200 itself can better reflect the temperature of the water. For example, the water tank 200 is made of stainless steel.

[0033] In the present application, the heat conducting component 500 is directly connected to the water tank 200 and the camera 120. As long as the water in the water tank 200 is hot water, the hot water will transfer heat to the water tank 200, and the heat of the water tank 200 will always be transferred to the camera 120 through the heat conducting component 500, that is, the camera 120 is always in a heated state. In this case, the user can avoid fogging of the lens 122 of the camera 120 at any time when receiving hot water from the water outlet 110, so that the camera 120 can obtain a clear image, thereby ensuring the normal operation of the special functions that rely on the camera 120, such as the liquid level detection based on the camera 120 to automatically stop the water when the cup is full. Moreover, heat conduction between the water tank 200 and the camera 120 is carried out in real time through the thermal conductive component 500, that is, the water tank 200 better reflects the temperature of the water contained in the water tank 200 in real time, and the thermal conductive component 500 better reflects the temperature of the water tank 200 in real time, and finally the camera 120 obtains heat to better reflect the temperature of the thermal conductive component 500. Although the intermediate conduction process is accompanied by a certain degree of heat loss, it can still increase the temperature of the camera 120 to a temperature close to the temperature of the water contained in the water tank 200 as a whole. The temperature of the water in the water tank 200 determines the temperature of the camera 120, so that the temperature of the camera 120 always changes adaptively based on the water temperature in the water tank 200. At the same time, it also eliminates the problem of the camera 120 needing to know whether defogging is currently required, and thus adaptively meets the actual usage needs of users. Specifically, when the water contained in the water tank 200 is hot water that can generate water vapor, the camera 120 is always in a heated state, and the user can connect hot water at any time to avoid fogging of the lens 122 of the camera 120. When the water contained in the water tank 200 is cold water that does not generate obvious water vapor, the camera 120 is not significantly heated by the heat-conducting component 500, and the lens 122 of the camera 120 does not need to be defogged.

[0034] The present application directly links the heating of the camera 120 with the water temperature in the water tank 200. There is no need to set up a heating device specifically for the camera 120, and there is no need to set up a matching water temperature detection device or water vapor / mist detection device to determine whether the defogger function needs to be activated. Only through the simple structural setting of the heat-conducting component 500, the camera 120 can be saved from judging whether the defogger function needs to be activated for the current water output situation, and the camera 120 can be heated adaptively to ensure that the heating and defogging of the camera 120 lens 122 always works when hot water is output, thereby ensuring the reliability of the liquid level detection function of stopping water when the cup is full, and greatly reducing the equipment cost.

[0035] In some embodiments, the heat-conducting component 500 is made of a flexible heat-conducting metal wire that can be bent to adapt to installation when placed in the electric kettle. Copper wire, which has high thermal conductivity, is preferably used. Specifically, in this embodiment, a single or multiple copper wires can be connected between the water tank 200 and the camera 120. Alternatively, multiple copper wires can be twisted to form a tightly wound copper rope, which is then connected between the water tank 200 and the camera 120 to increase the cross-sectional area and enhance thermal conductivity.

[0036] It should be noted that in this application, "hot water" refers to water that produces noticeable water vapor, and "cold water" refers to water that does not produce noticeable water vapor. The boundary is not limited to a specific water temperature. Noticeable water vapor can form a layer of mist on the lens 122 of the camera 120, thereby affecting the clarity of the image captured by the camera 120. In some embodiments, the boundary temperature between "hot water" and "cold water" can be between 45°C and 55°C, for example, 45°C, 50°C, or 55°C.

[0037] In the present application, the heat-conducting assembly 500 connects the water tank 200 and the camera 120, so the heat-conducting assembly 500 is in contact with at least the water tank 200 and the camera 120. In some embodiments, the heat-conducting assembly 500 includes a first connecting portion 510 and a second connecting portion 520. The first connecting portion 510 is disposed in contact with the outer wall of the water tank 200, and the second connecting portion 520 is disposed in contact with the outer wall of the camera 120. This connection is structurally simple and does not affect the inherent structures of the water tank 200 and the camera 120. That is, neither the water tank 200 nor the camera 120 requires an assembly structure specifically for connecting to the heat-conducting assembly 500, which simplifies installation and reduces production costs. In addition, the contact arrangement can improve the heat conduction efficiency between the heat-conducting assembly 500, the water tank 200, and the camera 120.

[0038] Furthermore, in the first embodiment, the first connection part 510 is arranged in contact with the outer wall of the water tank 200, the heat-conducting component 500 is a single copper wire, multiple copper wires or rope-shaped copper wire, and the first connection part 510 is a part of the heat-conducting component 500, that is, the first connection part 510 is also a copper wire. In order to improve the connection firmness, the connection is further improved. The first improvement method is to wrap the first connection part 510 around the outer wall of the water tank 200, and fix the first connection part 510 and the water tank 200 in the form of winding. The second improvement method is to fix the first connection part 510 and the water tank 200 through thermal conductive glue. The third improvement method is to combine the first two improvement methods, that is, to wrap the first connection part 510 around the outer wall of the water tank 200, and to set thermal conductive glue for fixation. In this way, the reliability of the first connection part 510 and the water tank 200 in contact with each other can be improved, and separation between the two can be avoided, thereby ensuring the heat conduction effect. In this embodiment, the second connecting part 520 is also a copper wire. The connection between the second connecting part 520 and the camera 120 can also be carried out in an improved manner between the above-mentioned first connecting part 510 and the water tank 200. The second connecting part 520 is wrapped around the camera 120 and / or fixed by a thermal conductive adhesive to improve the reliability of the second connecting part 520 and the camera 120 being in contact with each other, avoid separation between the two, and ensure the heat conduction effect.

[0039] Reference Figure 2 As shown, in the second embodiment, the heat-conducting component 500 includes a first connecting portion 510. The heat-conducting component 500 is made of a heat-conducting metal wire, preferably a copper wire, which can be a single copper wire, multiple copper wires or a rope-shaped copper wire. The first connecting portion 510 is a part of the heat-conducting component 500, that is, the first connecting portion 510 is also a copper wire. The first connecting portion 510 is spirally arranged on the side wall 210 of the water tank, and / or the first connecting portion 510 is coiled and abuts against the bottom wall 220 of the water tank.

[0040] In the second embodiment, the first embodiment is that the first connection portion 510 is spirally arranged around the side wall 210 of the water tank. Figure 2 As shown, the first connecting portion 510 forms a multi-turn coil that is in contact with the water tank side wall 210, effectively increasing the contact area between the first connecting portion 510 and the water tank 200, thereby improving the heat conduction efficiency, and the first connecting portion 510 can be fixed to the water tank 200 through the spiral arrangement, thereby improving the connection reliability between the heat conducting component 500 and the water tank 200. The cross-sectional shape of the water tank side wall 210 can be circular, rectangular or other shapes. Regardless of the shape of the water tank side wall 210, the first connecting portion 510 is arranged on the water tank 200 in a manner that is closely in contact with the water tank side wall 210.

[0041] In the second embodiment of the present invention, the first connecting portion 510 is wound at the same level to form a coiled shape, and the whole is flat and arranged close to the bottom wall 220 of the water tank. In actual application, in order to avoid the heating device 300 below the water tank 200, the first connecting portion 510 is usually wound into a ring with a hollow center, so that the first connecting portion 510 is arranged on the periphery of the heating device 300 and close to the outer portion of the bottom wall 220 of the water tank. Figure 2 shown.

[0042] The third embodiment of the second embodiment combines the first and second embodiments described above. The first connecting portion 510 includes both a portion spirally disposed around the water tank sidewall 210 and a portion coiled and abutting the water tank bottom wall 220. These two portions are connected, further increasing the contact area between the first connecting portion 510 and the water tank 200, thereby improving heat conduction efficiency. Furthermore, in this embodiment, the spiral and coiled portions of the first connecting portion 510 are connected to form an integral body that encloses the water tank 200 from bottom to top, further enhancing the reliability of the connection between the first connecting portion 510 and the water tank 200. In this embodiment, thermally conductive adhesive may be provided between the first connecting portion 510 and the water tank 200 for securement.

[0043] In the second embodiment, when the first connection portion 510 is arranged around the side wall 210 of the water tank, it is preferred that the first connection portion 510 is arranged around the side wall of the lower middle portion of the water tank 200. In this way, when the amount of water in the water tank 200 is small and the water level is low, the first connection portion 510 is still made to correspond to the water in the water tank 200 as much as possible, thereby improving the heat conduction efficiency.

[0044] Reference Figure 3As shown, based on the second embodiment, further improvements are made to obtain a third embodiment, in which the heat-conducting component 500 includes a first connecting portion 510, which is spirally arranged on the water tank side wall 210, and / or the first connecting portion 510 is coiled and abutted against the water tank bottom wall 220, and the water tank side wall 210 and / or the bottom wall is provided with an inner recess 230 whose winding shape matches the first connecting portion 510, and the first connecting portion 510 is arranged corresponding to the inner recess 230, thereby increasing the contact area between the first connecting portion 510 and the water tank side wall 210 and / or the bottom wall, thereby improving the heat conduction efficiency. In this embodiment, the heat conducting assembly 500 is made of a heat conducting metal wire, preferably copper wire, which can be a single copper wire, multiple copper wires, or a rope-shaped copper wire, preferably a rope-shaped copper wire. When the copper wire is correspondingly arranged in the inner recess 230, the portion of the copper wire facing the water tank 200 is abutted and wrapped by the inner recess 230, allowing heat conduction, while the portion of the copper wire facing away from the water tank 200 remains exposed, and there is no direct heat conduction between this portion and the water tank 200. Therefore, in this embodiment, a thermal conductive paste 600 is provided on the side of the first connecting portion 510 facing away from the water tank 200, and the thermal conductive paste 600 is connected to the outer wall of the water tank 200, so that heat from the water tank 200 is transferred to the side of the first connecting portion 510 facing away from the water tank 200 through the thermal conductive paste 600. In this way, the entire outer surface of the first connecting portion 510 can directly receive heat from the water tank 200, further improving the heat conduction efficiency.

[0045] In the present application, after obtaining heat from the water tank 200, the heat conducting component 500 needs to further conduct the obtained heat to the camera 120. In some embodiments, the heat conducting component 500 obtains the heat from the water tank 200 via a first connecting portion 510 connected to the water tank 200. In a fourth embodiment, the heat conducting component 500 includes a conducting portion 530, which extends from the water tank 200 to the camera 120 and conducts the heat obtained from the water tank 200 by the heat conducting component 500 to the camera 120. In this embodiment, the water outlet 110 and the camera 120 are both located at the upper portion of the housing 100, and the connection portion between the heat conducting component 500 and the water tank 200 can be at the upper portion, middle portion, or lower portion of the water tank 200. Therefore, the arrangement of the conducting portion 530 in this fourth embodiment can be implemented in a variety of specific ways.

[0046] The first implementation of the fourth embodiment refers to Figure 2As shown, the heat-conducting component 500 is connected to the middle or lower part of the water tank 200, that is, the water tank 200 connection end of the heat-conducting component 500 is significantly lower in height than the camera 120, so the conduction part 530 includes a main section 531 and a lead-out section 532. The main section 531 extends from bottom to top, and is used to conduct heat from bottom to top. The lead-out section 532 extends from the main section 531 toward the camera 120. A heat supply port 130 for the lead-out section 532 to extend is provided on the outer shell 100. The lead-out section 532 is used to conduct heat from the inside of the outer shell 100 to the outside, and finally to the camera 120, thereby achieving heating for the camera 120. In this embodiment, the main body section 531 is positioned against the water tank sidewall 210, allowing the main body section 531 to still absorb heat from the water tank 200, reducing heat loss from the conductive portion 530, and reducing the temperature difference between the end of the thermal conductive assembly 500 connected to the camera 120 and the end connected to the water tank 200, thereby improving thermal conductivity. In this embodiment, considering that the water level in the water tank 200 will continue to decrease during actual use, the thermal conductive assembly 500 is connected to the middle or lower portion of the water tank 200. This allows the end of the thermal conductive assembly 500 connected to the water tank 200 to be as close to the water in the water tank 200 as possible, thereby improving thermal conductivity efficiency.

[0047] Furthermore, in the first implementation of the fourth embodiment, the main body section 531 extends in the vertical direction, and the lead-out section 532 extends in the horizontal direction to reduce the total length of the conduction portion 530, thereby reducing heat loss. Furthermore, in this embodiment, the main body section 531 and the water tank side wall 210 can be fixed by thermally conductive glue. Furthermore, in this embodiment, the thermal conductive component 500 is preferably connected to the lower part of the water tank 200, that is, the part of the water tank side wall 210 close to the bottom wall, so that when the amount of water in the water tank 200 is small and the liquid level is low, the connection part between the thermal conductive component 500 and the water tank 200 can still correspond to the water in the water tank 200 as much as possible to ensure the heat conduction efficiency. Further, referring to Figure 5 As shown, in this embodiment, the main body section 531 is wrapped with a heat insulating member 700 on the side facing away from the water tank 200. This heat insulating member 700 wraps the main body section 531 in a semi-enclosed shape. The outer periphery of the lead-out section 532 is also wrapped with a heat insulating member 700. This heat insulating member 700 wraps the lead-out section 532 in a fully-enclosed shape, thereby further reducing the heat loss of the conduction part 530. For example, the heat insulating member 700 can be a heat shrink tube.

[0048] The second implementation of the fourth embodiment refers to Figure 6As shown, the heat conducting assembly 500 is connected to the upper portion of the water tank 200. That is, the water tank 200 connection end of the heat conducting assembly 500 is at a relatively low height relative to the camera 120. Therefore, the conductive portion 530 extends directly from the upper portion of the water tank 200 toward the camera 120. The housing 100 is provided with a heat supply port 130 for the conductive portion 530 to extend from. That is, the conductive portion 530 extends directly from the interior of the housing 100 to the exterior of the housing 100. The conductive portion 530 is used to conduct heat from the interior of the housing 100 to the exterior of the housing 100, and ultimately to the camera 120. This arrangement allows the conductive portion 530 to primarily conduct heat horizontally, shortening the conduction path, effectively reducing heat loss in the conductive portion 530, and saving material. It should be noted that in this embodiment, the conductive portion 530 can extend horizontally or at a certain angle, depending on the actual height difference between the water tank 200 connection end of the heat conducting assembly 500 and the camera 120 connection end. In this embodiment, the water tank 200 itself has good thermal conductivity, for example, it is made of stainless steel. Therefore, when the liquid level of the hot water in the water tank 200 is in the lower middle part of the water tank 200, the part of the lower middle part of the water tank 200 that is in contact with the hot water first obtains the heat of the hot water, and then the water tank 200 itself will conduct the heat from the lower middle part to the upper part, that is, the temperature consistency of the water tank 200 itself is good. In this way, even if the heat conduction component 500 is connected to the upper part of the water tank 200, it can still obtain heat close to the lower middle part of the water tank 200, and its heat conduction effect can still be guaranteed.

[0049] Reference Figure 4 、 Figure 5 and Figure 6 As shown, in the fifth embodiment, the heat-conducting component 500 includes a second connecting portion 520, and the heat-conducting component 500 is made of a heat-conducting metal wire, preferably a copper wire, which can be a single copper wire, multiple copper wires or a rope-shaped copper wire. The second connecting portion 520 is a part of the heat-conducting component 500, that is, the second connecting portion 520 is also a copper wire, and the camera 120 includes an annular lens holder 121 and a lens 122 arranged in the lens holder 121. The second connecting portion 520 is spirally arranged on the outer wall of the lens holder 121, which effectively increases the contact area between the second connecting portion 520 and the lens holder 121, thereby improving the heat conduction efficiency, and the spiral arrangement can fix the second connecting portion 520 to the lens holder 121, thereby improving the connection reliability between the heat-conducting component 500 and the camera 120. In this embodiment, the cross-sectional shape of the outer wall of the lens holder 121 can be circular, rectangular, or other shapes. However, regardless of the shape of the outer wall of the lens holder 121, the second connecting portion 520 is disposed around the lens holder 121 in close contact with the outer wall of the lens holder 121. Furthermore, in this embodiment, thermally conductive adhesive can be disposed between the second connecting portion 520 and the lens holder 121 for securement.

[0050] Reference Figure 7 As shown, in the sixth embodiment, a fan 800 is further provided on the housing 100 of the electric kettle, a temperature sensor 810 is provided at the water outlet 110, and a controller is provided in the housing 100. The fan 800 and the temperature sensor 810 are both electrically connected to the controller. The controller is used to control the start and stop of the fan 800 based on the real-time temperature of the temperature sensor 810. The fan 800 blows or draws air to remove water vapor, which on the one hand reduces the defogging pressure of the camera 120 lens 122 itself, and on the other hand reduces the fog in the field of view of the camera 120 lens 122, thereby further improving the clarity of the image captured by the camera 120. Specifically, in this embodiment, the controller pre-stores a temperature threshold. The temperature sensor 810 transmits the detected real-time temperature of the water outlet 110 to the controller. The controller compares the real-time temperature value with the temperature threshold. If the real-time temperature value is not less than the temperature threshold, the controller controls the fan 800 to start, blowing or sucking air toward the field of view of the lens 122 of the camera 120 to remove water vapor from the area. If the real-time temperature value is lower than the temperature threshold, the fan 800 does not start. In this embodiment, the temperature threshold is the boundary temperature value between "hot water" and "cold water", where "hot water" is water that produces significant water vapor, and "cold water" is water that does not produce significant water vapor. The boundary temperature value can be determined through experiments. For example, the boundary temperature value is within the range of 45-55 degrees Celsius, such as 45°C, 50°C, or 55°C. The temperature sensor 810 can be a thermistor.

[0051] Reference Figure 8As shown, in the seventh embodiment, a fan 800 is provided on the housing 100 of the electric kettle, and an electrothermal conversion device 820 is provided on the water outlet 110. The electrothermal conversion device 820 is electrically connected to the fan 800. The electrothermal conversion device 820 is used to convert the thermal energy of hot water into electrical energy to power the fan 800, so that the fan 800 can operate adaptively to remove water vapor. On the one hand, it reduces the defogging pressure of the camera 120 lens 122 itself, and on the other hand, it reduces the fog in the field of view of the camera 120 lens 122, thereby further improving the clarity of the image captured by the camera 120. Specifically, in this embodiment, the electrothermal conversion device 820 is disposed at the water outlet 110. When water is discharged from the water outlet 110, the water flows through the electrothermal conversion device 820, causing the water to contact the thermoelectric material in the electrothermal conversion device 820 to conduct heat. One end of the thermoelectric material is in close contact with the water flow pipe in the water outlet 110, while the other end is outside the water flow pipe to maintain a lower temperature. When hot water is discharged from the water outlet 110, a temperature difference is formed across the thermoelectric material, causing a voltage to be generated within the thermoelectric material. This electrical energy is then transmitted to the fan 800 to drive the fan 800. The fan 800 blows or draws air to remove water vapor from the field of view of the camera 120 lens 122. This embodiment achieves adaptive operation of the fan 800, eliminating the need for dedicated control of the fan 800. The fan 800 automatically activates when hot water is discharged from the water outlet 110. The higher the temperature of the hot water, the more water vapor is generated, the more electrical energy is supplied to the fan 800, the greater the power of the fan 800, and the greater the fan 800's ability to remove water vapor.
