Description

Technical Field

[0001] This application relates to the field of temperature testing equipment technology, and in particular to containers and water heaters. Background Technology

[0002] Temperature detection is crucial in many scenarios, including industrial production, scientific research, and daily life. Temperature sensors, as commonly used devices for temperature measurement, are widely applied in various environments. In related technologies, temperature sensors generally employ single-point temperature measurement. Under conditions of uniform temperature distribution and stable environment, temperature sensors can measure temperature relatively accurately, providing reliable temperature data support for the operation of related equipment or systems.

[0003] However, in many practical applications, temperature distribution is not always uniform. For example, the inner tank of an electric water heater is prone to temperature stratification. Relying solely on a single-point temperature sensor for measurement results in significant temperature deviations, failing to comprehensively and accurately reflect the overall temperature. Utility Model Content

[0004] The first technical problem solved by this invention is to provide a container that can effectively improve the accuracy of temperature detection.

[0005] The second technical problem solved by this utility model is to provide a water heater that can accurately detect the internal water temperature.

[0006] The first technical problem mentioned above is solved by the following technical solution: a container, the container comprising:

[0007] The inner liner has an internal cavity;

[0008] A resistive temperature sensing element, which is in the shape of a spiral strip, is used to wrap around the outer wall of the inner liner;

[0009] A limiting component is disposed on the outer wall of the inner liner to fix the resistive temperature sensing component on the inner liner.

[0010] The container described in this invention offers the following advantages compared to the prior art: The spiral-shaped resistive temperature sensing element is wound around the inner liner, and a limiting component ensures the stability of the connection between the resistive temperature sensing element and the inner liner. This ensures that different parts of the inner liner are in contact with the resistive temperature sensing element, facilitating comprehensive and accurate measurement of the overall temperature of the inner liner. Compared to single-point temperature measurement, this method more accurately reflects the overall temperature of the inner liner, thus improving the accuracy of temperature testing.

[0011] In one embodiment, the resistive temperature sensing component includes a temperature-sensing inner core and an insulating layer. The temperature-sensing inner core is made of a thermistor material, configured such that its resistance changes linearly with temperature. The insulating layer covers the outer surface of the temperature-sensing inner core. The thermistor material can quickly sense temperature changes in the inner liner and convert these temperature changes into a linearly changing resistance value, allowing the inner liner temperature to be calculated by detecting the resistance value. The presence of the insulating layer not only ensures the stable operation of the resistive temperature sensing component but also prevents short-circuit faults, improving safety.

[0012] In one embodiment, the limiting component includes: a first limiting member configured to connect to one end of the resistive temperature sensing component and the inner liner respectively; and a second limiting member configured to connect to the other end of the resistive temperature sensing component and the inner liner respectively. This structure can stably fix both ends of the resistive temperature sensing component to the inner liner, ensuring a tight fit between the resistive temperature sensing component and the inner liner, improving heat transfer efficiency, and making temperature measurement more accurate.

[0013] In one embodiment, the first limiting member includes a first limiting body and a first elastic pressure plate. The first limiting body is configured to connect with the inner liner, and the first elastic pressure plate is elastically connected to the first limiting body, forming a first limiting cavity between the first elastic pressure plate and the first limiting body. In one embodiment, the second limiting member includes a second limiting body and a second elastic pressure plate. The second limiting body is configured to connect with the inner liner, and the second elastic pressure plate is elastically connected to the second limiting body, forming a second limiting cavity between the second elastic pressure plate and the second limiting body. The first and second limiting cavities not only accurately position the resistive temperature sensing component but also utilize the elastic force of the first and second elastic pressure plates respectively to tightly press the resistive temperature sensing component, ensuring full contact between the resistive temperature sensing component and the inner liner, effectively preventing the resistive temperature sensing component from loosening or shifting.

[0014] In one embodiment, the limiting component further includes a third limiting member disposed between the first limiting member and the second limiting member, the third limiting member being configured to connect to the middle portion of the resistive temperature sensing component and the inner liner, respectively. The third limiting member further secures the resistive temperature sensing component, preventing it from shaking or shifting relative to the inner liner.

[0015] In one embodiment, there are multiple third limiting members, which are spaced apart along the arrangement path of the resistive temperature sensing component, with adjacent third limiting members having the same spacing. This uniform distribution of third limiting members makes the resistive temperature sensing component more evenly and stably fixed on the inner liner, enabling it to perceive temperature changes of the inner liner more comprehensively and evenly, and avoiding temperature measurement errors caused by poor local contact of the resistive temperature sensing component.

[0016] In one embodiment, the third limiting member includes a first limiting protrusion and a second limiting protrusion, which are configured to connect with the inner liner, and a limiting gap is provided between the first limiting protrusion and the second limiting protrusion. In another embodiment, the third limiting member may include a connecting portion and a bent portion, the connecting portion being configured to connect with the inner liner, and the bent portion connecting with the connecting portion, so that the bent portion, the connecting portion, and the inner liner form a third limiting cavity. The third limiting member with the above structure enables the resistive temperature sensing component to stably measure the inner liner temperature, improving the accuracy and reliability of the temperature test results.

[0017] The second technical problem mentioned above is solved by the following technical solution: a water heater, including a container as described in any of the above.

[0018] The water heater described in this utility model has the following advantages compared with the prior art: Based on the structural design of the container, the spiral strip-shaped resistive temperature sensing component is wound around the inner tank, and the connection between the resistive temperature sensing component and the inner tank is ensured by the limiting component, so that the resistive temperature sensing component is in contact with different parts of the inner tank, thereby enabling a more comprehensive and accurate measurement of the overall temperature of the inner tank and improving the accuracy of temperature testing.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] See Figures 1 to 3 As shown, an embodiment of this application provides a container 10 including an inner liner 20, a resistive temperature sensing component 100, and a limiting component 300, used to detect the overall temperature of the inner liner 20. Exemplarily, the inner liner 20 has a can-like structure and an inner cavity. It should be noted that, for ease of understanding, the following embodiments use an example where the inner liner 20 has a can-like structure and is installed horizontally relative to the ground. Figure 1 As shown in the diagram, the Z-axis represents the vertical direction of gravity in the tank-like structure, and the X-axis represents the horizontal direction. All descriptions of directions in this text can be understood using the definitions provided here. Of course, the shape and installation configuration of the inner liner 20 are not limited to... Figure 1 As shown, in other optional embodiments, the inner liner 20 can be in the form of a cylindrical structure, a cubic structure, etc., and the installation angle of the inner liner 20 can also be vertical or inclined relative to the ground.

[0035] The resistive temperature sensing element 100 is in the form of a spiral strip and is configured to be wound around the outer wall of the inner liner 20. Exemplarily, the resistive temperature sensing element 100 may be a resistive temperature sensor capable of sensing temperature changes, etc., and when the resistive temperature sensing element 100 is wound around the inner liner 20, it has multiple points of contact with the inner liner 20. Figure 2 As shown, a spiral-shaped resistive temperature sensing element 100 is wound around the outer surface of the inner liner 20. The cross-section F-F' of the inner liner 20 intersects the resistive temperature sensing element 100 at five points, with cross-section F-F' perpendicular to the Z-direction. At this point, the liquid at cross-section F-F' of the inner liner 20 has five contact points f with the resistive temperature sensing element 100. Therefore, the temperature of the liquid at the same height can be measured more than five times using the resistive temperature sensing element 100, allowing for a relatively accurate measurement of the overall water temperature. It should be understood that the number of intersection points between the cross-section of the inner liner 20 and the resistive temperature sensing element 100 is not limited to five. Depending on the specific shape of the inner liner 20 and the winding method of the resistive temperature sensing element 100, the corresponding number of intersection points can also be two, three, four, six, seven, etc.

[0036] The limiting component 300 is configured to connect to both the resistive temperature sensing component 100 and the inner liner 20, thereby fixing the resistive temperature sensing component 100 onto the inner liner 20. By connecting the resistive temperature sensing component 100 and the inner liner 20 through the limiting component 300, the resistive temperature sensing component 100 can be securely positioned on the surface of the inner liner 20, ensuring good heat transfer between the resistive temperature sensing component 100 and the inner liner 20. Thus, the resistive temperature sensing component 100 can promptly detect temperature changes in the inner liner 20 to obtain temperature data.

[0037] With the above structural design, when performing temperature detection, the spiral strip-shaped resistive temperature sensing component 100 is tightly attached to the outer surface of the inner liner 20, and then the resistive temperature sensing component 100 is connected to an external control board (not shown in the figure). The control board obtains parameters such as the resistance value of the resistive temperature sensing component 100, thereby obtaining the temperature of the inner liner 20 corresponding to the resistive temperature sensing component 100.

[0038] Therefore, the resistive temperature sensing component 100 of this embodiment can comprehensively acquire temperature information at different locations within the inner tank 20, facilitating a comprehensive and accurate measurement of the overall temperature of the inner tank 20. Compared to single-point temperature measurement, this container 10 can more accurately reflect the overall temperature of the inner tank 20, effectively avoiding temperature measurement deviations caused by localized temperature anomalies, and improving the accuracy of temperature testing. It has promising application prospects in fields such as electric water heaters and boilers.

[0039] See Figure 4As shown, in some embodiments, the resistive temperature sensing component 100 includes a temperature-sensing inner core 110 and an insulating layer 120. The temperature-sensing inner core 110 is connected to the test component and is made of a thermistor material configured such that its resistance value changes linearly with temperature. Because the resistance value of the thermistor material exhibits a good linear relationship with temperature, the resistive temperature sensing component 100 is installed on the outer wall of the inner liner 20. The temperature-sensing inner core 110 can quickly sense the temperature change of the inner liner 20 and convert the temperature change into a linearly changing resistance value. After the test component obtains the resistance value, the temperature of the inner liner 20 can be accurately determined through simple linear calculation. Compared to ordinary thermistor materials, the linear characteristic makes temperature measurement more accurate and calculation simpler, providing more accurate temperature data. Furthermore, the insulation layer 120 is made of insulating material and covers the outer surface of the temperature-sensing inner core 110. The insulation layer 120 can effectively prevent the temperature-sensing inner core 110 from making electrical contact with the metal shell of the inner liner 20 or other live parts, thus preventing short circuit faults.

[0040] For example, taking the liquid temperature range inside the inner liner 20 as 0~80 degrees Celsius, the resistance value of the corresponding thermistor changes linearly within this temperature range. This thermistor can effectively reflect the overall temperature of the entire inner liner 20. The testing principle of the thermistor can be understood as dividing the thermistor into n equal segments, denoted as a1, a2, a3, ..., an. These n segments of the thermistor can continuously measure the temperature changes in the contact area.

[0041] Specifically, let the relationship between the resistance of the thermistor and temperature be: R = aT + b, where R is the resistance of the thermistor, T is the temperature of the thermistor, and a and b are constants.

[0042] The resistance values ​​of the n segments of the thermistor material can be expressed as: R1=aT1+b, R2=aT2+b, ..., Rn=aTn+b.

[0043] When the temperature at various points inside the inner liner 20 stabilizes at T1, the corresponding total resistance Rw at the stable temperature is: Rw=R1+R2+…Rn=naT1+nb.

[0044] When the temperature at various points inside the inner liner 20 fluctuates between T1 and Tn, the total resistance Rb during the corresponding temperature fluctuation is: Rb = R1 + R2 + ... + Rn = a(T1 + T2 + ... + Tn) + nb.

[0045] The ratio of the total temperature Tw when the temperature is stable at T1 to the total temperature Tb when the temperature fluctuates between T1 and Tn is:

[0046]

[0047] The ratio of the total resistance Rw when the temperature is stable at T1 to the total resistance Rb when the temperature fluctuates between T1 and Tn satisfies the following relationship:

[0048]

[0049] Where n and b are reference values ​​for the thermistor material, determined by its physical properties. A comparison shows that after subtracting the reference resistance nb, the ratio of total temperature to total resistance is proportional to the aforementioned ratio relationship between the total resistance and the reference resistance.

[0050] Therefore, if the temperature distribution of the inner liner 20 is uneven, the resistance value of each section will also change with different temperatures. Since the resistance value and temperature are linearly related, the change in the total resistance value also reflects the temperature average. That is, when the total resistance value remains basically unchanged, it indicates that the temperature distribution is uniform. At this time, the measured temperature can accurately reflect the overall temperature.

[0051] Furthermore, in some embodiments, the resistive temperature sensing element 100 is uniformly wound around the outer side of the inner liner 20, with each turn of the resistive temperature sensing element 100 having the same size. For example, see... Figure 2 As shown, for the detection of liquid temperature inside the cylindrical inner liner 20, a resistive temperature sensing element 100 is evenly wound around the outside of the cylindrical inner liner 20, ensuring that the length, cross-sectional area, and height of each ring of the resistive temperature sensing element 100 are consistent, and the spacing between adjacent rings of the resistive temperature sensing element 100 is the same. This ensures that the resistive temperature sensing element 100 is evenly distributed on the outer surface of the inner liner 20, allowing for sufficient contact and heat exchange between the resistive temperature sensing element 100 and the liquid inside the inner liner 20. As the liquid temperature changes, each part of the resistive temperature sensing element 100 responds synchronously, and the resistance value changes accordingly. After measuring the resistance value and converting it to temperature, relatively uniform temperature data can be obtained throughout the inner liner 20, effectively reflecting the overall temperature of the liquid inside the inner liner 20.

[0052] Reference Figure 2 and Figure 3 As shown, in some embodiments, the limiting component 300 includes a first limiting member 310 and a second limiting member 320. The first limiting member 310 is configured to connect to one end of the resistive temperature sensing component 100 and the inner liner 20, respectively, and the second limiting member 320 is configured to connect to the other end of the resistive temperature sensing component 100 and the inner liner 20, respectively. The first limiting member 310 and the second limiting member 320 stably fix both ends of the resistive temperature sensing component 100 to the outer surface of the inner liner 20, respectively, ensuring the smooth operation of the temperature measurement process.

[0053] Reference Figure 5As shown, in some embodiments, the first limiting member 310 includes a first limiting body 311 and a first elastic pressure plate 312. The first limiting body 311 is configured to connect with the inner liner 20, and the first elastic pressure plate 312 is elastically connected to the first limiting body 311, forming a first limiting cavity 313 between the first elastic pressure plate 312 and the first limiting body 311. Exemplarily, the first limiting body 311 can be welded to the outer surface of the inner liner 20. One end of the first elastic pressure plate 312 is elastically connected to the first limiting body 311, and the other end of the first elastic pressure plate 312 has a gap with the first limiting body 311. A portion of the first elastic pressure plate 312 protrudes away from the first limiting body 311, so that the first elastic pressure plate 312 and the first limiting body 311 form the first limiting cavity 313. Through the elastic action of the first elastic pressure plate 312, the resistive temperature sensing component 100 can be clamped within the first limiting cavity 313. Therefore, the first limiting cavity 313 can not only accurately position the resistive temperature sensing component 100, but also use the elastic force of the first elastic pressure plate 312 to tightly press the resistive temperature sensing component 100, effectively preventing the resistive temperature sensing component 100 from loosening or shifting, while facilitating the disassembly and limiting of the resistive temperature sensing component 100.

[0054] Furthermore, in some embodiments, the second limiting member 320 includes a second limiting body and a second elastic pressure plate. The second limiting body is configured to connect with the inner liner 20, and the second elastic pressure plate is elastically connected to the second limiting body, forming a second limiting cavity between the second elastic pressure plate and the second limiting body. Thus, the first elastic pressure plate 312 is elastically connected to the first limiting body 311, and the first limiting cavity 313 formed by the two clamps one end of the resistive temperature sensing component 100; simultaneously, the second limiting body of the second limiting member 320 is fixed to the other end of the inner liner 20, the second elastic pressure plate is elastically connected to the second limiting body, and the second limiting cavity clamps the other end of the resistive temperature sensing component 100, thereby ensuring a more stable limiting of the resistive temperature sensing component 100.

[0055] For example, the structure of the second limiting member 320 can be set to be the same as that of the first limiting member 310, so as to play the same role as the first limiting member 310.

[0056] Reference Figure 2 and Figure 3As shown, in some embodiments, the limiting member 300 further includes a third limiting member 330, which is disposed between the first limiting member 310 and the second limiting member 320. The third limiting member 330 is configured to connect to the middle portion of the resistive temperature sensing member 100 and the inner liner 20, respectively. The third limiting member 330 can further fix the resistive temperature sensing member 100, preventing it from shaking or shifting on the surface of the inner liner 20, ensuring that the resistive temperature sensing member 100 exchanges heat with the inner liner 20 more stably, so that the temperature data obtained by the testing member is more accurate and reliable.

[0057] Furthermore, in some embodiments, there are multiple third limiting members 330, which are spaced apart along the arrangement path of the resistive temperature sensing component 100, and the spacing between adjacent third limiting members 330 is the same. The arrangement path of the resistive temperature sensing component 100 refers to the morphological orientation of the resistive temperature sensing component 100 itself, i.e., the arrangement path of the resistive temperature sensing component 100 is a spiral strip. The same spacing means that the spacing between adjacent third limiting members 330 along the arrangement path of the resistive temperature sensing component 100 is the same. Specifically, when the resistive temperature sensing component 100 is evenly wound around the inner liner 20, the spacing between adjacent third limiting members 330 in the horizontal direction is the same, and the spacing between adjacent third limiting members 330 in the vertical direction is the same. (Refer to...) Figure 2 As shown, multiple third limiting members 330 are respectively installed at the upper and lower edges of the inner tank 20. The distance between adjacent third limiting members 330 in the horizontal direction (X direction) is L, and the distance between adjacent third limiting members 330 in the vertical direction (Z direction) is H, so that the multiple third limiting members 330 are evenly distributed on the inner tank 20. This uniform distribution of third limiting members 330 makes the resistive temperature sensing component 100 more evenly and stably fixed on the inner tank 20. By limiting the arrangement path of the resistive temperature sensing component 100 by multiple third limiting members 330, the water temperature change in the inner tank 20 can be sensed more comprehensively and evenly, avoiding temperature measurement errors caused by poor local contact of the resistive temperature sensing component 100, thus facilitating accurate measurement of the overall temperature.

[0058] Reference Figure 6As shown, in some embodiments, the third limiting member 330 includes a first limiting protrusion 331 and a second limiting protrusion 332, which are configured to connect with the inner liner 20. A limiting gap 333 is provided between the first limiting protrusion 331 and the second limiting protrusion 332. Exemplarily, the first limiting protrusion 331 and the second limiting protrusion 332 are respectively mounted on the outer surface of the inner liner 20 and spaced apart along the X-direction, with a limiting gap 333 along the X-direction between them. This limiting gap 333 can hold the resistive temperature sensing component 100 and precisely limit its position, ensuring that the resistive temperature sensing component 100 is evenly wound around the inner liner 20 for accurate temperature measurement. Furthermore, the limiting separation of the resistive temperature sensing component 100 from the inner liner 20 is convenient.

[0059] Reference Figure 7 As shown, in some embodiments, the third limiting member 330 includes a connecting portion 334 and a bent portion 335. The connecting portion 334 is configured to connect with the inner liner 20, and the bent portion 335 is connected to the connecting portion 334 so that the bent portion 335, the connecting portion 334, and the inner liner 20 form a third limiting cavity 336. Exemplarily, the connecting portion 334 and the inner liner 20 can be connected by welding, bolts, or other methods. The bent portion 335 protrudes in a direction away from the inner liner 20, and both ends of the bent portion 335 are connected to the inner liner 20 via the connecting portion 334. When the connecting portion 334 is fixed to the outer surface of the inner liner 20, the bent portion 335, the connecting portion 334, and the inner liner 20 form the third limiting cavity 336. Inserting the resistive temperature sensing component 100 into the third limiting cavity 336 ensures that the resistive temperature sensing component 100 is tightly fitted and securely connected to the outer surface of the inner liner 20, facilitating stable measurement of the inner liner 20 temperature.

[0060] Another embodiment of this application provides a water heater, which includes the aforementioned container 10. Exemplarily, a resistive temperature sensing element 100 is wound around the outer wall of the inner tank 20. A limiting member 300 ensures the stability of the connection between the resistive temperature sensing element 100 and the inner tank 20, and ensures that the resistive temperature sensing element 100 is in contact with different parts of the inner tank 20, thereby enabling a more comprehensive and accurate measurement of the overall temperature of the inner tank 20, improving the accuracy of temperature testing, and facilitating precise temperature control of the water heater.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
