Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a water heater. Background Art

[0002] A water heater consists of an inner tank, seals, heating tubes, a mounting plate, and a thermal circuit breaker. The mounting plate is installed in the inner tank's mounting hole, the heating tubes are installed in the inner tank and connected to the mounting plate, and the thermal circuit breaker is located inside the inner tank and mounted on the mounting plate. Because the inner tank and mounting plate are separated by a seal with low thermal conductivity, the thermal circuit breaker primarily detects abnormal operating conditions through thermal radiation.

[0003] However, when the water heater is dry-burning, the thermal circuit breaker mainly senses the abnormal temperature through thermal radiation. Therefore, the reaction time of the anti-dry-burn protection action is relatively long. As a result, when the thermal circuit breaker takes the anti-dry-burn protection action, the water heater has been dry-burning for a period of time, causing damage to the inner tank and related components.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the utility model.

[0026] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the utility model.

[0027] See also Figures 1 to 5 , an embodiment of the present utility model proposes a water heater 10, the water heater 10 includes a first inner tank 100, a first mounting plate 200, a first heating tube 300, a first sealing member 400 and a thermal circuit breaker 500, the first inner tank 100 is provided with a first internal space and a first mounting hole, the first mounting hole is connected to the first internal space; the first mounting plate 200 is installed in the first mounting hole to cover the first internal space; the first heating tube 300 is connected to the first mounting plate 200 and is located in the first internal space; the first sealing member 400 is arranged around the edge of the first mounting hole and is located between the first mounting plate 200 and the first inner tank 100; the thermal circuit breaker 500 is located in the first internal space and contacts the wall surface of the first inner tank 100; when the detection temperature detected by the thermal circuit breaker 500 is greater than the preset temperature, the thermal circuit breaker 500 disconnects the power input end of the water heater 10.

[0028] In this way, through direct contact, the thermal circuit breaker 500 can sense the change in the inner tank temperature more quickly. Compared with the traditional method of relying on thermal radiation, it significantly shortens the time interval from detecting an abnormality to taking protective measures, reducing the risk of damage caused by prolonged dry burning.

[0029] As you can understand, unlike traditional mounting locations, this thermal breaker 500 is designed to directly contact the inner wall of the first inner container 100. This allows it to directly sense temperature changes on the inner container wall, allowing for a more rapid response to abnormal conditions. When the detected temperature exceeds a preset value, the thermal breaker 500 immediately activates, disconnecting the power input and halting the heating process.

[0030] Under normal operating conditions, thermal breaker 500 remains closed, allowing current to flow and power the heating element. If a dry boil occurs (i.e., insufficient water to cover the heating element), the temperature of the inner pot wall will rise rapidly. Because thermal breaker 500 is in direct contact with the inner pot wall, it can quickly sense this temperature change and respond in time before dangerous temperatures are reached, disconnecting the circuit and preventing overheating and damage.

[0031] In some embodiments, the first inner liner 100 is made of a corrosion-resistant material and has a first internal space for storing water and a first mounting hole connected to the first internal space. The first mounting plate 200, which may be a flange, is secured to the first mounting hole to seal the first internal space and prevent water leakage. The first heating tube 300 is mounted within the inner liner via the first mounting plate 200 to heat the water. The first sealing member 400, which may be a sealing ring, is located between the first mounting plate 200 and the first inner liner 100 and is positioned around the edge of the first mounting hole to ensure a good seal.

[0032] In some embodiments, a first resistance wire is provided in the first heating tube 300, and the first resistance wire is electrically connected to the power input terminal through the thermal circuit breaker 500. One end of the first resistance wire is connected to the power input terminal (such as the power grid) through a wire, and the other end is connected to a contact of the thermal circuit breaker 500 through a wire. The other contact of the thermal circuit breaker 500 is connected to the rest of the circuit, usually a ground wire or other safety device. Under normal circumstances, the thermal circuit breaker 500 remains closed, allowing current to flow through the first resistance wire for heating. If the water level in the inner tank is too low, resulting in dry burning, or if the temperature of the inner tank wall exceeds a preset safety threshold due to other reasons, the thermal circuit breaker 500 will act quickly to cut off the connection between the first resistance wire and the power supply, stop the heating process, and prevent equipment damage and potential safety risks.

[0033] In this way, the thermal circuit breaker 500 is directly integrated into the heating circuit, which simplifies the complexity of the electrical control system, reduces the manufacturing cost, and improves the reliability of the system.

[0034] In some embodiments, the water heater 10 further includes a second inner tank 610, a second mounting plate 620, a second heating tube 630, and a second seal 640, wherein the second inner tank 610 is connected to the first inner tank 100, and the second inner tank 610 is located below the first inner tank 100; the second inner tank 610 is provided with a second internal space and a second mounting hole, and the second mounting hole is connected to the second internal space; the second mounting plate 620 is installed in the second mounting hole to cover the second internal space; the second heating tube 630 is connected to the second mounting plate 620 and is located in the second internal space; the second seal 640 is arranged around the edge of the second mounting hole and is located between the second mounting plate 620 and the second inner tank 610.

[0035] Among them, the second inner tank 610 is made of corrosion-resistant material, and is provided with a second internal space for storing water and a second mounting hole connected to the second internal space. The second mounting plate 620 can be a flange plate, fixed on the second mounting hole, to cover the second internal space to ensure that water does not leak. The first heating tube 300 is installed in the inner tank through the second mounting plate 620 for heating water. The second sealing member 640 can be a sealing ring, located between the second mounting plate 620 and the second inner tank 610, and is arranged around the edge of the second mounting hole to ensure good sealing. In this way, since the water heater 10 has two inner tanks, it helps to increase the water storage capacity of the water heater 10.

[0036] When the first heating tube 300 of the first inner tank 100 is dry-burned, the thermal circuit breaker 500 can quickly respond to the abnormal temperature of the inner tank through heat radiation and heat conduction of the inner tank; when the second heating tube 630 of the second inner tank 610 is dry-burned, since the area affected by the heat radiation of the first inner tank 100 is large and the hot air of the second inner tank 610 flows upward, the thermal circuit breaker 500 can also quickly respond to the abnormal temperature of the second inner tank 610 through heat conduction and heat convection of the second inner tank 610.

[0037] When the water heater 10 has multiple heating tubes, only a single thermal circuit breaker 500 is required to monitor the abnormal temperature of the inner tank.

[0038] In some embodiments, a first resistance wire is provided in the first heating tube 300 , and a second resistance wire is provided in the second heating tube 630 . Both the first resistance wire and the second resistance wire are electrically connected to the power input terminal through the thermal circuit breaker 500 .

[0039] One end of a first resistor is connected to the power input via a wire. The other end of the first resistor is connected to a contact of a thermal circuit breaker 500 via a wire. One end of a second resistor is also connected to the power input via a wire. The other end of the second resistor is also connected to another contact of the thermal circuit breaker 500 via a wire. The output of the thermal circuit breaker 500 is connected to the rest of the circuit, typically to ground or another safety device.

[0040] Under normal circumstances, thermal circuit breaker 500 remains closed, allowing current to flow through the first and second resistance wires for heating. If the water level in either tank is too low, causing a dry boil, or if the tank wall temperature exceeds a preset safety threshold for other reasons, thermal circuit breaker 500 will quickly activate, severing the connection between the first and second resistance wires and the power supply, halting all heating processes and preventing equipment damage and potential safety risks.

[0041] In this way, by simultaneously monitoring two heating tubes through a thermal circuit breaker 500, the power supply of the entire system can be immediately cut off when an abnormality occurs in any heating tube, providing more comprehensive safety protection.

[0042] In addition, a single thermal circuit breaker 500 is used to control the two heating tubes, which simplifies the complexity of the electrical control system, reduces manufacturing costs, and improves system reliability.

[0043] In some embodiments, the thermal circuit breaker 500 is a snap-action thermal circuit breaker. A snap-action thermal circuit breaker typically includes a bimetallic strip or similar sensitive element that is highly sensitive to temperature changes. When the temperature reaches a preset threshold, the bimetallic strip bends, triggering a switch action.

[0044] The snap-action thermal circuit breaker has an extremely fast response speed, operating quickly when the temperature exceeds the preset threshold. This rapid response helps to promptly cut off power in abnormal operating conditions such as dry boiling, reducing damage to the inner tank and related components.

[0045] In addition, the snap-action thermal circuit breaker is relatively low in cost and easy to manufacture and maintain, which reduces the overall cost of the water heater 10 while maintaining high safety performance.

[0046] The snap-action thermal circuit breaker is connected in series between the power input and the first heating tube 300, and between the power input and the second heating tube 630. Under normal circumstances, the thermal circuit breaker 500 remains closed, allowing current to flow through the first and second heating tubes 300 and 630 for heating. If the temperature of the inner tank wall exceeds a set safety threshold, the bimetallic strip within the thermal circuit breaker 500 will rapidly bend, causing the contacts to separate, thereby disconnecting the power input and stopping the heating process.

[0047] In some embodiments, the thermal circuit breaker 500 has a temperature-sensing surface provided with a heat-conducting member.

[0048] A heat conducting member, such as thermally conductive silicone, thermal paste, or other high-thermal-conductivity material, is disposed on the temperature-sensing surface of the thermal breaker 500. The heat conducting member enhances the heat conduction efficiency between the temperature-sensing surface and the inner wall, enabling the thermal breaker 500 to sense temperature changes more quickly and accurately.

[0049] The thermal breaker 500, coated with a heat conductive material, is tightly attached to the inner wall of the container, ensuring that the temperature sensing surface is in full contact with the inner wall. A clamp, screw, or other fixing device can be used to securely mount the thermal breaker 500 to the inner wall to prevent it from loosening or falling off.

[0050] Thus, the presence of the heat conductor significantly improves the efficiency of heat conduction between the temperature-sensing surface of the thermal circuit breaker 500 and the wall of the first inner container 100. This enables the thermal circuit breaker 500 to sense temperature changes on the wall of the first inner container 100 more quickly, thereby shortening the time interval between detecting abnormal temperatures and taking protective measures, and reducing damage caused by abnormal operating conditions such as dry burning.

[0051] In addition, the use of the heat conductor eliminates the air gap between the temperature sensing surface and the inner wall, reducing thermal resistance and improving the accuracy of temperature transfer. This helps the thermal circuit breaker 500 detect the actual temperature more accurately, thereby providing more reliable protection.

[0052] Furthermore, the use of the heat conducting member enhances the thermal coupling between the thermal circuit breaker 500 and the inner container wall, reducing malfunction or non-operation caused by poor contact, thereby improving the reliability and stability of the entire system.

[0053] In some embodiments, the thermally conductive member is thermally conductive silicone. This material exhibits excellent thermal conductivity, significantly improving the efficiency of heat transfer between the temperature-sensing surface of the thermal breaker 500 and the inner container wall. This allows the thermal breaker 500 to more quickly detect temperature changes on the inner container wall, shortening the time between detecting abnormal temperatures and initiating protective measures, thereby reducing damage caused by abnormal operating conditions such as dry heating.

[0054] Furthermore, the thermally conductive silicone eliminates the air gap between the temperature-sensing surface and the inner wall, reducing thermal resistance and improving the accuracy of temperature transfer. This helps the thermal breaker 500 detect the actual temperature more accurately, resulting in more reliable protection.

[0055] Furthermore, thermally conductive silicone rubber generally has high temperature resistance and can operate stably and long-term in high-temperature environments without failure or decomposition due to high temperatures, thus ensuring the long-term reliability of thermal circuit breaker 500. Thermally conductive silicone rubber also has excellent aging resistance and is not prone to hardening, cracking, or loss of thermal conductivity, ensuring the efficient operation of thermal circuit breaker 500 throughout its service life.

[0056] In some embodiments, the thermal breaker 500 is positioned near the first heating tube 300. Placing the thermal breaker 500 near the first heating tube 300 significantly shortens the heat conduction path, allowing the thermal breaker 500 to more quickly sense temperature changes near the heating tube. This helps the breaker respond quickly to abnormal operating conditions such as dry cooking, minimizing damage to the inner pot and related components.

[0057] In addition, the thermal circuit breaker 500 disposed near the heating pipe can more accurately detect the temperature near the first heating pipe 300, reducing the temperature transmission delay caused by the long distance. This improves the accuracy of temperature detection and thus improves the reliability of the protection action.

[0058] In some embodiments, the water heater 10 further includes a mounting fixture 700, through which the thermal circuit breaker 500 is connected to the first inner tank 100. The mounting fixture 700 is used to secure the thermal circuit breaker 500 to the inner tank wall. The mounting fixture 700 can be a metal clip, a screw fastener, or other suitable fastening device. Ensure that the mounting fixture 700 is securely fastened to prevent the thermal circuit breaker 500 from loosening or falling off during operation.

[0059] In this way, the thermal circuit breaker 500 is firmly fixed to the wall of the inner tank using the mounting fixture 700, which can ensure that the thermal circuit breaker 500 will not loosen or fall off due to vibration or other external forces during operation, thereby improving the overall reliability of the system.

[0060] Furthermore, by securing the thermal breaker 500 with the mounting fixture 700, close contact between its temperature-sensing surface and the inner tank wall is ensured, reducing air gaps and improving the accuracy of temperature transmission. This helps the thermal breaker 500 detect the actual temperature more accurately, thereby providing more reliable protection.

[0061] Moreover, the design of the mounting fixture 700 simplifies the installation process of the thermal circuit breaker 500. The user or technician only needs to place the thermal circuit breaker 500 in a suitable position and fix it with the mounting fixture 700, without the need for complicated installation steps, thus reducing the difficulty of installation.

[0062] In some embodiments, the mounting fixture 700 is removably attached to the first inner container 100. The water heater 10 uses screws and nuts to secure the mounting fixture 700 to the inner container wall. The screws can be secured through pre-drilled holes, ensuring a secure and reliable thermal breaker 500. The water heater 10 features a mounting fixture 700 with a snap-fit ​​mechanism that snaps directly onto the inner container wall. This design facilitates quick installation and removal.

[0063] Thus, the detachable mounting fixture 700 makes it easier and faster to replace and maintain the thermal circuit breaker 500. A user or technician can easily remove the old thermal circuit breaker 500 and install a new one, reducing maintenance time and cost.

[0064] Furthermore, during maintenance, the detachable mounting fixture 700 allows a technician to quickly disassemble the thermal circuit breaker 500, inspect and repair the relevant components, and then reinstall it, greatly simplifying the maintenance process.

[0065] In some embodiments, the core of the snap-action thermal circuit breaker is a bimetallic strip, which is composed of two metals with different thermal expansion coefficients laminated together. Typically, one metal has a higher thermal expansion coefficient and the other has a lower thermal expansion coefficient.

[0066] When the temperature rises, the metal with a high thermal expansion coefficient will expand more than the metal with a low thermal expansion coefficient, causing the bimetallic strip to bend. Under normal operating conditions, the bimetallic strip is in a straight state, the contacts are closed, and current can flow through the first heating tube 300 and the second heating tube 630 to heat.

[0067] When the temperature rises to the preset action temperature, the bimetallic strip bends due to thermal expansion and the contacts separate, thereby cutting off the circuit and stopping the heating process.

[0068] Once the temperature drops below the reset temperature, the bimetallic strip returns to its flat state, the contacts reclose, and the circuit is connected again (if it is an automatic reset thermal circuit breaker).

[0069] A thermal breaker 500 with an operating temperature slightly higher than the normal operating temperature but lower than the dangerous temperature is selected based on the design and safety requirements of the water heater 10. For example, if the normal operating temperature of the water heater is 60°C, a thermal breaker 500 with an operating temperature of 90°C or higher can be selected.
