Description

Technical Field

[0001] The present disclosure relates to an electrical appliance, and particularly to a heating device. Background Art

[0002] A heating device refers to a device that can heat the liquid contained therein, such as an electric thermos.

[0003] When the heating device heats the liquid, it is necessary to monitor the temperature change of the liquid in order to control the opening and closing of heating and the heating power.

[0004] To accurately monitor the temperature of the liquid in the heating device, a temperature detection device needs to be provided in the heating device. Currently, there are generally two methods. One is to set the temperature detection device outside the inner container of the heating device. In this detection method, the temperature detection device does not directly contact the liquid in the inner container, and there is an error between the detected temperature and the actual temperature of the liquid. The other is to set the temperature detection device in the inner container of the heating device. In this method, the temperature detection device is in direct contact with the liquid, and the reflected temperature is relatively accurate. However, the temperature detection device will be directly exposed to the user's view, resulting in a decrease in aesthetics. Summary of the Utility Model

[0005] To overcome the problems existing in the related art, the present disclosure provides a heating device.

[0006] According to an aspect of an embodiment of the present disclosure, there is provided a heating device, including an inner container, a temperature detection device, and a liquid outlet pipeline. The inner container is used to hold the liquid; the temperature detection device is used to detect the liquid temperature; the liquid outlet pipeline is communicated with the inner container, and at least a part of the temperature detection device is arranged in the liquid outlet pipeline.

[0012] In some embodiments, the first convex portion extends circumferentially along the second pipeline to form a closed loop.

[0014] In some embodiments, the heating device includes a base, and the base includes a partition provided below the bottom wall of the inner container. The partition includes a through hole and a guide pipe. The guide pipe extends from the edge of the through hole towards the bottom wall of the inner container, and the guide pipe is sleeved on the outer wall of the second pipeline.

Detailed implementation manners

[0032] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0033] The present disclosure provides a heating device, which may include an inner container, a temperature detection device, and a liquid outlet pipeline. The inner container is used for containing liquid; the temperature detection device is used for detecting the liquid temperature; the liquid outlet pipeline is communicated with the inner container, and the temperature detection device is at least partially disposed in the liquid outlet pipeline.

[0034] In the present disclosure, the liquid in the inner container and the liquid in the liquid outlet pipeline are always kept in communication, and the temperature changes are consistent. Disposing the temperature detection device at least partially in the liquid outlet pipeline can not only directly contact the liquid to obtain accurate temperature, but also be hidden from the user's view to improve the aesthetics.

[0035] The heating device refers to a device for heating the liquid contained therein. For example, the heating device is an electric thermos, which is used for heating the water in the electric thermos. In some embodiments, the heating device can also heat other liquids, such as milk, tea, coffee, etc., and the present disclosure does not limit this.

[0036] Figure 1 is a schematic structural diagram of a heating device shown according to an exemplary embodiment. As Figure 1 shown, the heating device may include an inner container 1, a temperature detection device 4, and a liquid outlet pipeline 3. The inner container 1 is used for containing liquid; the temperature detection device 4 is used for detecting the liquid temperature; the liquid outlet pipeline 3 is communicated with the inner container 1, and the temperature detection device 4 is at least partially disposed in the liquid outlet pipeline 3.

[0037] The liquid in the inner container 1 is transported through the liquid outlet pipeline 3 outside the heating device for the user to use. In some embodiments, the liquid can be injected from the top of the inner container 1, or from the bottom wall 13 or the side wall, and different settings can be made according to needs.

[0038] The liquid in the liquid outlet pipeline 3 is in communication with the liquid in the inner container 1, and the temperature changes are consistent. The temperature of the liquid in the liquid outlet pipeline 3 can basically reflect the temperature of the liquid in the inner container 1.

[0039] In this embodiment, the temperature detection device 4 is at least partially arranged in the liquid outlet pipeline 3. The temperature detection device 4 is in direct contact with the liquid in the liquid outlet pipeline 3, and can accurately detect the temperature of the liquid in the liquid outlet pipeline 3. And the temperature of the liquid in the liquid outlet pipeline 3 is the same as the temperature of the liquid in the inner container 1, so as to accurately detect the temperature of the liquid in the inner container 1. At the same time, because the temperature detection device 4 is not installed in the inner container 1, but hidden in the liquid outlet pipeline 3, the temperature detection device 4 will not appear in the user's field of vision when the user opens the inner container 1, improving the aesthetics of the heating device.

[0040] The temperature detection device 4 being at least partially arranged in the liquid outlet pipeline 3 means that the temperature detection device 4 can be entirely arranged in the liquid outlet pipeline 3, or only a part including the temperature sensor probe can be arranged in the liquid outlet pipeline 3.

[0041] In some embodiments, the temperature sensor can be an NTC sensor. The NTC sensor has high precision and small volume, which can not only improve the temperature measurement accuracy, but also be convenient for installation and hiding, enhancing the aesthetics.

[0042] In some embodiments, as Figure 1 shown, a liquid outlet 11 is provided on the bottom wall 13 of the inner container 1, and the liquid outlet pipeline 3 is in communication with the inner container 1 through the liquid outlet 11.

[0043] Providing the liquid outlet 11 on the bottom wall 13 can avoid the problem that the temperature of the liquid in the liquid outlet pipeline 3 cannot be consistent with the temperature of the liquid in the inner container 1 when the liquid volume is low, and can be applicable to accurate temperature detection at different liquid volumes.

[0044] In some embodiments, a heating plate 12 is provided on the bottom wall 13 of the inner container 1, and the liquid outlet 11 is arranged avoiding the heating plate 12. For example, the heating plate 12 is arranged in the middle of the bottom wall 13 of the inner container 1, and the liquid outlet 11 is provided at the edge of the bottom wall 13 of the inner container 1.

[0045] When heated, the temperature of the heating plate 12 will be higher than that of the liquid in the inner container 1. If the liquid outlet 11 is opened on the heating plate 12 or is too close to the heating plate 12, it may cause the temperature of the liquid in the liquid outlet pipe 3 to increase faster than that of the liquid in the inner container 1, resulting in the temperature of the liquid in the liquid outlet pipe 3 not accurately reflecting the temperature of the liquid in the inner container 1 and causing inaccurate temperature measurement.

[0046] Figure 2 is a schematic structural diagram of a heating device shown according to an exemplary embodiment. As Figure 2 shown, the heating device may include a pump body 33 connected in series in the liquid outlet pipe 3, and the temperature detection device 4 is arranged between the liquid outlet 11 and the pump body 33.

[0047] The heating device realizes automatically pumping out the liquid in the inner container 1 by connecting the pump body 33 in the liquid outlet pipe 3, which is convenient for use. However, the pump body 33 will, to a certain extent, cut off the heat transfer in the liquid outlet pipe 3, resulting in a relatively large temperature difference on both sides of the pump body 33 in the liquid outlet pipe 3, and the temperature of the liquid on the side of the pump body 33 close to the liquid outlet 11 of the inner container 1 is the closest to the temperature of the liquid in the inner container 1.

[0048] In this embodiment, arranging the temperature detection device 4 between the pump body 33 and the liquid outlet 11 of the inner container 1 can avoid the problem of inaccurate temperature measurement caused by the influence of the pump body 33 on heat transfer and the measured temperature not representing the temperature of the liquid in the inner container 1, effectively improving the accuracy of the detected temperature.

[0049] In some embodiments, the liquid outlet pipe 3 extends downward from the liquid outlet 11 of the inner container 1 for a certain distance and then extends upward to a higher position to facilitate the user to pick up the liquid. The section of the liquid outlet pipe 3 extending downward from the liquid outlet 11 of the inner container 1 is relatively short, and the temperature detection device 4 is arranged in this section of the liquid outlet pipe 3, which is close to the inner container 1 and can more accurately detect the temperature of the liquid in the inner container 1.

[0050] Figure 3 is a partial structural schematic diagram of a heating device shown according to an exemplary embodiment, Figure 4 is Figure 3 a longitudinal sectional view. As Figure 3 、 Figure 4 shown, the liquid outlet pipe 3 may include a first pipe 31 and a second pipe 32. The first pipe 31 may include a first end 311 and a second end 312, and the liquid in the inner container 1 flows out through the second end 312; one end of the second pipe 32 is communicated with the liquid outlet 11 of the inner container 1, and the other end of the second pipe 32 is communicated with the first end 311 of the first pipe 31.

[0051] When the heating device heats the liquid in the inner container 1, it will also be affected by heat and expand and deform. As the temperature of the liquid in the inner container 1 decreases, the heating device will contract and deform. During the expansion and contraction process, gaps may be generated at the joint between the liquid outlet pipeline 3 and the inner container 1 due to deformation, resulting in liquid leakage.

[0052] The liquid outlet pipeline 3 is set to include two parts, a first pipeline 31 and a second pipeline 32 that are connected. The second pipeline 32 is connected to the liquid outlet 11 of the inner container 1. The connection between the first pipeline 31 and the second pipeline 32 actually plays a buffering role. During the thermal expansion and contraction of the inner container 1 and the liquid outlet pipeline 3 itself, the expansion is absorbed and the contraction is compensated through the connection between the first pipeline 31 and the second pipeline 32, so that the first pipeline 31 of the liquid outlet pipeline 3 can always be in close contact with the bottom wall 13 of the inner container 1, avoiding liquid leakage.

[0053] In some embodiments, the first end 311 of the first pipeline 31 is sleeved on the second pipeline 32, and the first pipeline 31 and the second pipeline 32 are in interference fit to form a seal to prevent liquid from leaking between the first pipeline 31 and the second pipeline 32.

[0054] In some embodiments, the second pipeline 32 may include at least one of silica gel, elastic plastic, and rubber. In other embodiments, the first pipeline 31 may include at least one of plastic, metal, and ceramic.

[0055] The second pipeline 32 can also be made of other elastic or flexible materials, as long as it can be in close contact with the bottom wall 13 of the inner container 1 and be tightly connected to the first end 311 of the first pipeline 31 to achieve a seal.

[0056] A filter element 34 can be provided at one end of the second pipeline 32 connected to the inner container 1. The filter element 34 is detachably provided in the second pipeline 32 or the liquid outlet 11 of the inner container 1. It can effectively prevent impurities and dirt from entering the liquid outlet pipeline 3, not only cleaning the liquid output by the heating device, but also exempting the liquid outlet pipeline 3 from frequent cleaning. At the same time, because the position where the filter element 34 is provided is relatively easy to access, it is convenient to disassemble and replace.

[0057] Figure 5 It is a longitudinal sectional schematic diagram of a partial structure of a heating device shown according to an exemplary embodiment. Figure 6 It is Figure 5 The enlarged view of part A in. As Figure 5 、 Figure 6 shown, the second pipeline 32 includes a first protrusion 324. The first protrusion 324 is provided on the inner wall of the second pipeline 32 and extends circumferentially along the second pipeline 32. The first end 311 of the first pipeline 31 abuts against the first protrusion 324.

[0058] The first end 311 of the first pipeline 31 is partially inserted into the second pipeline 32. By providing a first protrusion 324 that abuts against the first end 311 of the first pipeline 31, a limiting effect can be exerted on the first pipeline 31, providing a limit and positioning for the insertion depth of the first pipeline 31 in the second pipeline 32, making the installation more accurate.

[0059] In some other embodiments, as Figure 6 shown, the first protrusion 324 extends circumferentially along the second pipeline 32 to form a closed loop.

[0060] In this embodiment, by setting the first protrusion 324 as a closed loop circumferentially along the second pipeline 32, the first protrusion 324 can be made to seal with the port of the first pipeline 31, preventing the liquid in the inner tank 1 from leaking through the gap between the first pipeline 31 and the second pipeline 32. At the same time, the first protrusion 324 also has a certain width in the radial direction of the first pipeline 31. Even if the first pipeline 31 and the second pipeline 32 have different thermal expansion and contraction speeds and amplitudes, the first protrusion 324 with a certain width and forming a closed loop can always abut against the port of the first pipeline 31 to form a seal.

[0061] In some other embodiments, as Figure 6 shown, the first end 311 of the first pipeline 31 includes a second protrusion 313. The second protrusion 313 is provided on the outer wall of the first end 311 of the first pipeline 31 and extends circumferentially along the first pipeline 31, and the second pipeline 32 abuts against the second protrusion 313.

[0062] The second protrusion 313 has a limiting effect on the second pipeline 32, preventing over-insertion when the first pipeline 31 is inserted into the second pipeline 32 and making the installation more accurate.

[0063] In some embodiments, there may be a certain distance between the second protrusion 313 and the end of the second pipeline 32, that is, they are spaced apart, leaving a certain space for the expansion of the second pipeline 32.

[0064] In some embodiments, as Figure 6 shown, the second protrusion 313 extends circumferentially along the first pipeline 31 to form a closed loop. After the second protrusion 313 abuts against the end of the second pipeline 32, a seal is formed, preventing the liquid in the inner tank 1 from flowing out through the gap between the first pipeline 31 and the second pipeline 32.

[0065] In some embodiments, as Figures 3 to 5As shown, the heating device includes a base 2. The base 2 includes a partition 21 disposed below the bottom wall 13 of the inner tank 1. The partition 21 includes a through hole 211 and a guiding tube 212. The guiding tube 212 extends along the edge of the through hole 211 towards the bottom wall 13 of the inner tank 1, and the guiding tube 212 is sleeved on the outer wall of the second pipeline 32.

[0066] The guiding tube 212 plays a guiding and limiting role in the radial direction of the second pipeline 32, aligning the second pipeline 32 with the liquid outlet 11 of the inner tank 1, and avoiding liquid leakage caused by the misalignment of the second pipeline 32 with the liquid outlet 11.

[0067] In some embodiments, as Figure 6 shown, one end of the second pipeline 32 close to the inner tank 1 is turned outwards to form a flanging 321. One side of the guiding tube 212 close to the inner tank 1 is inserted into the flanging 321, and the guiding tube 212, the flanging 321, and the bottom wall 13 of the inner tank 1 are sequentially abutted.

[0068] The guiding tube 212 disposed on the partition 21 applies a pressure to the flanging 321 of the second pipeline 32 towards the bottom wall 13 of the inner tank 1, preventing the second pipeline 32 from falling off under the action of gravity. At the same time, the guiding tube 212 tightly presses the flanging 321 of the second guiding tube 212 and the bottom wall 13 of the inner tank 1 together to form a seal, preventing liquid leakage between the second pipeline 32 and the bottom wall 13 of the inner tank 1.

[0069] At the same time, in this embodiment, the installation between the second pipeline 32, the bottom wall 13 of the inner tank 1, and the flanging 321 is simple, without the need to use other sealing components or adhesives, simplifying the installation and disassembly processes.

[0070] In some embodiments, the base 2 is fixedly connected to the inner tank 1, and the distance between the partition 21 and the bottom wall 13 of the inner tank 1 is fixed. By setting the distance between the partition 21 and the bottom wall 13 of the inner tank 1 and the length of the guiding tube 212, the guiding tube 212 can apply pressure to the flanging 321 of the second pipeline 32.

[0071] In some embodiments, as Figures 3 to 6 shown, a first temperature measuring hole 214 penetrating the guiding tube 212 is provided on the side wall of the guiding tube 212, and a second temperature measuring hole 323 penetrating the second pipeline 32 is provided on the side wall of the second pipeline 32. At least part of the temperature detection device 4 passes through the first temperature measuring hole 214 and the second temperature measuring hole 323 to detect the liquid temperature in the second pipeline 32.

[0072] By disposing the temperature detection device 4 on the second pipeline 32, which is relatively close to the inner tank 1, the temperature detection accuracy can be effectively improved.

[0073] In some embodiments, the first temperature measurement hole 214 on the guide tube 212 is arranged to extend along the axial direction of the guide tube 212.

[0074] During thermal expansion and contraction of the guide tube 212 and the second pipeline 32, there may be problems of asynchronous expansion and contraction or different expansion and contraction amplitudes, which may cause the second temperature measurement hole 323 on the second pipeline 32 to move along the axial direction of the guide tube 212. As a result, a shearing force may be generated on the temperature detection device 4 by the first temperature measurement hole 214 and the second temperature measurement hole 323, which may not only damage the temperature detection device 4 but also loosen the joints between the temperature detection device 4 and the first temperature measurement hole 214 and the second temperature measurement hole 323, thereby leading to seal damage and liquid leakage.

[0075] In this embodiment, the first temperature measurement hole 214 on the guide tube 212 is arranged to extend along the axial direction of the guide tube 212. When the second pipeline 32 undergoes thermal expansion and contraction and the second temperature measurement hole 323 moves, it can move along the first temperature measurement hole 214, and the first temperature measurement hole 214 will not have an adverse effect on the temperature detection device 4, which not only improves the reliability of the seal between the temperature detection device 4 and the second temperature measurement hole 323 but also avoids damage to the temperature detection device 4.

[0076] In some embodiments, the temperature detection device 4 can be entirely arranged in the second pipeline 32, and only wires (including power lines and signal lines) need to pass through the first temperature measurement hole 214 and the second temperature measurement hole 323.

[0077] In some embodiments, as Figure 6 shown, the outer shape of the temperature detection device 4 is a rod-shaped structure with a gradually increasing diameter from one end to the other end. The end of the temperature detection device 4 with a smaller diameter passes through the first temperature measurement hole 214 and the second temperature measurement hole 323 with the end with a larger diameter outside and is inserted into the second pipeline 32.

[0078] The temperature detection device 4 is arranged on the second pipeline 32 by means of insertion, and the installation is simple. Moreover, the diameter of the temperature detection device 4 gradually increases from one end to the other end until the temperature detection device 4 can be in interference fit with the second temperature measurement hole 323, which can not only achieve sealing but also has low requirements for the dimensional accuracy of the second temperature measurement hole 323 on the second pipeline 32, reducing the production difficulty.

[0079] In some embodiments, the maximum diameter of the temperature detection device 4 is greater than the diameter of the second temperature measurement hole 323, and the minimum diameter of the temperature detection device 4 is less than the diameter of the second temperature measurement hole 323.

[0080] In some embodiments, as Figures 3 to 6 shown, the guide tube 212 can be provided with a first positioning portion 213, and the second pipeline 32 can be provided with a second positioning portion 322. The shapes of the first positioning portion 213 and the second positioning portion 322 are adapted to each other.

[0081] The first temperature measuring hole 214 on the guide pipe 212 and the second temperature measuring hole 323 on the second pipeline 32 need to be aligned so that the temperature detection device 4 can be inserted. The first positioning portion 213 and the second positioning portion 322 with adaptable shapes will align the second pipeline 32 and the guide pipe 212 in the circumferential direction of the guide pipe 212, so as to align the first temperature measuring hole 214 and the second temperature measuring hole 323.

[0082] In some embodiments, as Figures 3 to 6 shown, a groove-shaped first positioning portion 213 is formed by the inner side wall of the guide pipe 212 being recessed inward from the inside out, and the groove-shaped first positioning portion 213 extends along the axial direction of the guide pipe 212; a second positioning portion 322 is formed by a part of the outer side wall of the second pipeline 32 protruding outward from the inside out, and the second positioning portion 322 extends along the axial direction of the second pipeline 32. The second positioning portion 322 can be inserted into the first positioning portion 213 to achieve circumferential positioning of the second pipeline 32 in the guide pipe 212.

[0083] In other embodiments, a first positioning portion 213 is formed by a part of the inner side wall of the guide pipe 212 protruding inward, and the first positioning portion 213 extends along the axial direction of the guide pipe 212; a groove-shaped second positioning portion 322 is formed by the outer side wall of the second pipeline 32 being recessed inward from the outside out, and the groove-shaped second positioning portion 322 extends along the axial direction of the second pipeline 32. The first positioning portion 213 can be inserted into the first positioning portion 213 to achieve circumferential positioning of the second pipeline 32 in the guide pipe 212.

[0084] In some embodiments, as Figures 3 to 6 shown, the first temperature measuring hole 214 can be opened on the first positioning portion 213, and the second temperature measuring hole 323 can be opened on the second positioning portion 322.

[0085] The first temperature measuring hole 214 and the second temperature measuring hole 323 need to be aligned with each other so that the temperature detection device 4 can be inserted. If the first temperature measuring hole 214 and the second temperature measuring hole 323 are set at any positions in the circumferential direction of the guide pipe 212 and the second pipeline 32, it is difficult to position and it is easy to measure inaccurately.

[0086] In this embodiment, opening the first temperature measuring hole 214 on the first positioning portion 213 and opening the second temperature measuring hole 323 on the second positioning portion 322 facilitate positioning and measurement, and make the opening positions of the first temperature measuring hole 214 and the second temperature measuring hole 323 more accurate.

[0087] Figure 7 is a schematic structural diagram of a heating device shown according to an exemplary embodiment, Figure 8 is Figure 7 a longitudinal sectional view. As Figure 7 、 Figure 8As shown, the heating device includes a housing 5, a top cover 6, and a base 2, where the housing 5 is disposed between the top cover 6 and the base 2. In some embodiments, the housing 5 may be integrally provided with the top cover 6 or may be provided with the top cover 6 in an openable and closable manner (such as pressing to open and close or flip to open and close). In some embodiments, the housing 5 and the base 2 may be integrally provided or may be detachably provided.

[0088] The inner tank 1 of the heating device is disposed in the housing 5, between the top cover 6 and the base 2.

[0089] The heating device further includes a liquid receiving port 7 for the user to pick up the liquid. The liquid receiving port 7 is disposed at the upper part of the heating device and may be connected to the top cover 6, or may be connected to the housing 5, or may be connected to both the top cover 6 and the housing 5 at the same time. The first end 311 of the first pipeline 31 is communicated with the second pipeline 32, and the second end 312 extends into the liquid receiving port 7 to discharge the liquid outward. In some embodiments, the liquid receiving port 7 is disposed above the pump body 33, and the first pipeline 31 extends directly upward after passing through the pump body 33, which can minimize the length of the first pipeline 31.

For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the front and rear associated objects. The singular forms of "a", "the", and "said" are also intended to include the plural forms unless the context clearly indicates otherwise.

[0092] Furthermore, it can be understood that the terms "first", "second", etc. are used to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other and do not represent a specific order or importance. In fact, the expressions such as "first" and "second" can be used interchangeably. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0093] It can be further understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "lateral", "front", "rear", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this embodiment and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0094] It can be further understood that unless otherwise specified, "connection" includes direct connection without other components between the two, and also includes indirect connection with other elements between the two.

[0095] It can be further understood that although the operations are described in a specific order in the drawings in the embodiments of the present disclosure, it should not be understood as requiring the operations to be performed in the specific order shown or in a serial order, or requiring all the operations shown to obtain the desired result. In a specific environment, multitasking and parallel processing may be advantageous.
