Description

Technical Field

[0001] This application relates to the field of water supply technology, and in particular to a hot water tank and water supply device. Background Technology

[0002] In the water supply equipment industry, the heating tank, as an indispensable core component, plays a crucial role. Its stability and efficiency not only determine the overall heat exchange efficiency of the water supply equipment but are also closely related to consumers' drinking water safety. However, despite continuous advancements in heating tank design and technology, its built-in temperature control element remains one of the key factors restricting the improvement of water supply equipment performance and safety assurance.

[0003] Traditional temperature control elements (including temperature sensors) are generally designed to be built into the heating tank, directly monitoring the temperature of steam or water inside to regulate the heating unit's operation. The initial intention of this design was to ensure that the temperature control element could accurately capture temperature fluctuations inside the heating tank, thereby achieving precise temperature control. However, in practical applications, this built-in design has gradually revealed its inherent shortcomings, particularly in terms of lag in controlling the heating tank's shutdown mechanism.

[0004] Because the temperature control element is directly exposed to the high-temperature environment inside the hot water tank, it inevitably suffers from corrosion and pressure after a period of use, causing its response speed to gradually decrease. When the internal temperature of the hot water tank gradually rises to the preset upper limit, the temperature control element often cannot immediately detect this change and react quickly. Instead, it needs a relatively long time delay to trigger the shutdown command of the heating system. This lag not only weakens the accuracy and timeliness of temperature control but also creates a hidden danger of overheating in the hot water tank during frequent heating or emergencies. Once the temperature of the hot water tank exceeds the safe range, it may not only damage the water dispenser but also cause fires and other safety accidents, seriously threatening the lives and property of consumers.

[0005] Besides the inherent lag, the built-in design of traditional temperature control elements also presents inconveniences in maintenance and replacement. Because the temperature control element is firmly fixed inside the heating tank, if a malfunction occurs, maintenance personnel often need to disassemble the entire heating tank for inspection or replacement. This not only increases the complexity and cost of maintenance but may also damage the sealing and overall structure of the heating tank, thereby affecting the reliability and lifespan of the drinking water equipment.

[0006] Therefore, the inventors have proposed a hot water tank and water supply device to solve the above-mentioned technical problems. Utility Model Content

[0007] In view of this, this application provides a hot water tank and a water supply device to solve the problem that traditional hot water tanks cannot monitor temperature in real time, leading to overheating. To achieve one or more of the above objectives, or other objectives, this application proposes a hot water tank, including a hot water tank body;

[0008] The heat tank body has a hollow structure and is used to store the heat exchange medium.

[0009] Temperature control components;

[0010] The temperature control element includes a temperature sensor;

[0011] The temperature sensor is attached to the outer wall of the hot tank body.

[0012] Furthermore, at least two temperature sensors are provided, and the at least two temperature sensors are arranged vertically relative to the hot tank body.

[0013] Furthermore, the hot tank body has a suction port and a return port. The suction port is close to the upper end of the hot tank body, and the return port is close to the lower end of the hot tank body. At least one of the temperature sensors is flush with or close to the suction port, and / or, at least one of the temperature sensors is flush with or close to the return port.

[0014] Furthermore, at least one of the temperature sensors is disposed at the bottom of the hot tank body, and / or, at least one of the temperature sensors is disposed on the side of the hot tank body.

[0015] Furthermore, the temperature control element also includes a temperature control unit, which is connected to a heating unit.

[0016] Furthermore, the temperature control unit includes a mounting component and a temperature control switch; the number of temperature control switches is multiple.

[0017] Furthermore, the temperature control switch is detachably mounted on the mounting component, and the temperature control switch includes a first temperature controller that can be automatically reset and a second temperature controller whose trigger temperature is higher than that of the first temperature controller and requires manual reset.

[0018] Furthermore, the mounting component includes a mounting plate and two side plates, with the two side plates respectively fixedly mounted on the two sides of the mounting plate; the mounting plate is fixed to the hot tank body via the two side plates. According to the above technical solution, the use of multiple temperature control switches designed to be detachably mounted on the mounting component brings significant advantages to the temperature control of the hot tank body. This not only improves the accuracy and flexibility of temperature control, allowing the hot tank body to be set and adjusted to various temperatures according to actual needs, but also facilitates the replacement, upgrading, or repair of the temperature control switches by users or maintenance personnel, reducing maintenance costs and time. In addition, the configuration of multiple temperature control switches enhances the safety and stability of the hot tank, ensuring reliable temperature control under different operating conditions and extending the service life of the hot tank body.

[0019] According to the above technical solution, the mounting component, as the supporting structure of the temperature control switch, consists of a mounting plate and two side plates. The two side plates are fixedly installed on the two sides of the mounting plate to form a stable frame. This frame is fixed to the appropriate position of the hot tank body by the two side plates, ensuring that the temperature control switch can be closely attached to the outer wall of the hot tank body for temperature monitoring. When the temperature of the hot tank body changes, the temperature control switch will open or close according to the preset temperature threshold, thereby achieving precise control of the heating unit.

[0020] Furthermore, the mounting plate is provided with mounting slots, the diameter of which is adapted to the diameter of the temperature control switch;

[0021] The temperature control switch is fixed to the mounting plate through the mounting slot.

[0022] According to the above technical solution, the mounting slot on the mounting plate has a diameter precisely matched to the diameter of the temperature control switch, providing a stable mounting position for the temperature control switch. During installation, the temperature control switch passes through the mounting slot and is fixed to the mounting plate using appropriate fasteners (such as screws). This not only ensures that the temperature control switch can stably monitor the temperature changes of the hot tank, but also facilitates subsequent maintenance and replacement. When the temperature of the hot tank changes, the temperature control switch will automatically turn on or off according to the preset temperature threshold, achieving precise control of the heating unit.

[0023] Furthermore, the mounting plate has at least one first mounting hole, and the temperature control switch has at least one second mounting hole. Each first mounting hole and each second mounting hole are correspondingly provided, and the first mounting hole and the second mounting hole are adapted to each other.

[0024] Wherein, the first mounting hole and / or the second mounting hole are arc-shaped holes.

[0025] According to the above technical solution, at least one first mounting hole on the mounting plate corresponds to at least one second mounting hole on the temperature control switch, and the diameters or shapes of the two are compatible, providing the temperature control switch with flexible installation and fine-tuning possibilities. Specifically, when the first and / or second mounting holes are designed as arc-shaped holes, the temperature control switch is allowed to be adjusted within a certain range of angles on the mounting plate to adapt to different installation requirements or optimize the position of the temperature monitoring point. During installation, the operator can fix the temperature control switch to the mounting plate by passing fasteners (such as screws) through the corresponding first and second mounting holes. Due to the existence of the arc-shaped holes, the operator can fine-tune the temperature control switch before fixing, ensuring that it can be close to the outer wall of the heating tank at the optimal angle and position, thereby more accurately monitoring temperature changes. After the temperature control switch is securely mounted on the mounting plate, it can operate according to the preset temperature threshold, achieving precise control of the heating unit.

[0026] On the other hand, this application also proposes a water supply device, including a housing and a heat exchange assembly, wherein the heat exchange assembly is disposed within the housing;

[0027] The heat exchange assembly includes a heat exchanger;

[0028] It also includes a hot tank as described above; the hot tank is connected to the heat exchanger.

[0029] Furthermore, the heat exchanger has a drinking water channel and a heat exchange medium channel, the heat exchange medium channel being connected to the suction port and the return port of the hot tank.

[0030] The beneficial effects of this utility model are:

[0031] This invention employs a temperature sensor and multiple temperature control switches. The temperature sensor is located on the outer wall of the heating tank, which avoids the influence of the high-temperature environment inside the tank on the temperature control element. This enables precise monitoring and control of the heating tank's temperature. The thermally conductive silicone grease applied between the temperature sensor and the heating tank further improves heat transfer efficiency, ensuring that the temperature control switches can accurately sense temperature changes. The temperature control switches can promptly disconnect when they detect that the heating tank is too hot, preventing overheating and thus achieving precise control of the heating unit. This not only improves the heating efficiency of the heating tank but also enhances the safety and stability of the drinking water equipment, effectively preventing overheating and extending the service life of the heating tank.

[0032] The temperature sensor is installed on the outside of the hot tank body. Compared with existing technologies, this avoids the traditional temperature control components being directly exposed to the high-temperature environment inside the hot tank body, which can be affected by corrosion and pressure, thus improving the service life of the device.

[0033] The temperature control switch in this invention is detachable and has an arc-shaped hole on the mounting plate, allowing for fine-tuning of the temperature control switch. This design not only facilitates the replacement, upgrading, or repair of the temperature control switch by users or maintenance personnel, reducing maintenance costs and time, but also improves installation flexibility, enabling the temperature control switch to be placed close to the outer wall of the hot tank at the optimal angle and position, thereby more accurately monitoring temperature changes and ensuring the long-term stable operation of the hot tank.

Detailed Implementation

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] On the one hand, this embodiment proposes a hot pot, such as Figures 1 to 5 As shown, the device includes a heat tank body 1 and a temperature control element. The heat tank body 1 is a hollow structure and is used to store a heat exchange medium, such as water or other suitable fluids, to achieve heat transfer and preheat drinking water. The temperature control element includes a temperature sensor 2, which is installed on the outer wall of the heat tank body 1.

[0049] Temperature sensor 2 is installed on the upper part of the hot tank body 1 and / or near the heating unit 4.

[0050] In one embodiment, the temperature sensor 2 is installed at the upper part of the hot tank body 1. By installing the temperature sensor 2 at the upper part of the hot tank body 1, the temperature sensor 2 can monitor the temperature inside the hot tank body 1 in real time, effectively preventing overheating due to lack of water and avoiding dry burning.

[0051] In one embodiment, the temperature sensor 2 is installed near the heating unit 4. Temperature monitoring near the heating unit 4 can effectively prevent overheating, ensure the stable operation of the heating unit 4, and extend the service life of the device.

[0052] The number of temperature sensors 2 is at least one. However, to more accurately monitor the temperature distribution inside the heating tank body 1, multiple temperature sensors 2 can be installed, including those installed at the top of the heating tank body 1 and those installed near the heating unit 4. When installing multiple temperature sensors 2, they can be arranged in a vertically spaced configuration. Since the heating tank body 1 draws hot water from the top and cold water flows back from the bottom, this arrangement can accurately capture the temperature distribution characteristics of the heating tank body 1, where the water is hot at the top and cold at the bottom. The heating tank body 1 has a suction port and a return port. The suction port is located near the top of the heating tank body 1, and the return port is located near the bottom of the heating tank body 1. At least one temperature sensor 2 is flush with or near the suction port, and / or at least one temperature sensor 2 is flush with or near the return port. Through multiple vertically spaced temperature sensors 2, the temperature changes inside the heating tank body 1 can be monitored in real time, thereby achieving precise control and optimization.

[0053] Specifically, at least one of the temperature sensors 2 may be disposed at the bottom of the hot tank body 1, and / or at least one of the temperature sensors 2 may be disposed on the side of the hot tank body 1.

[0054] The temperature sensor 2 and the hot tank body 1 can be installed in a fixed or detachable manner. Specifically, the temperature sensor 2 can be connected to the hot tank body 1 by adhesive or by bolt.

[0055] Temperature sensor 2 can be a surface-mount temperature sensor.

[0056] When the temperature sensor 2 is attached to the outer wall of the heat exchange medium 1, the heat will be transferred to the outside through the heat tank wall when the heat exchange medium inside the heat tank is heated. The temperature sensor 2 can sense the temperature change of the outer wall of the heat tank body 1 in real time, ensuring the accuracy of temperature measurement and response speed.

[0057] As a preferred embodiment, such as Figure 5 As shown, the heat exchange tank body 1 includes a square tank cylinder 11 and two end caps 12; the two end caps 12 and the square tank cylinder 11 together form a cavity for storing the heat exchange medium, and the temperature sensor 2 is installed on the square tank cylinder 11 and / or the end caps 12. Preferably, as... Figure 1 As shown, temperature sensor 2 is installed on the square can 11.

[0058] When the heat exchange medium inside the heat tank body 1 is heated, the heat is transferred to the outside through the square tank cylinder 11 and end cap 12, causing a temperature change sensed by the temperature sensor 2. The temperature sensor 2 is connected to a display that can display the monitored temperature. The temperature control strategy can be adjusted according to the temperature displayed on the display, and the heating unit 4 can be controlled, such as turning off the heating unit 4 or adjusting the power of the heating unit 4, to ensure that the temperature inside the heat tank body 1 is maintained within a safe range.

[0059] Meanwhile, in this embodiment, the temperature sensor 2 is installed by attaching it to the surface. This not only facilitates installation and debugging, but also makes it easy to disassemble and replace the surface-mount sensor when it malfunctions or needs to be replaced, reducing maintenance costs and ensuring the long-term stable operation of the hot tank body 1.

[0060] In a preferred embodiment, the temperature control element further includes a temperature control unit 3, which is connected to a heating unit 4. The temperature control unit 3 and the heating unit 4 are connected in a controlled manner to form a closed loop. The temperature control unit 3 can open or close the loop according to the temperature of the outer wall of the hot tank body 1.

[0061] According to the above technical solution, the temperature control unit 3 and the heating unit 4 form a closed loop through a control connection. The heating unit 4 is responsible for adjusting the working state of the heating unit 4 according to the actual temperature of the hot tank body 1, thereby achieving precise control of the temperature of the hot tank body 1. When the heat exchange medium in the hot tank body 1 needs to be heated, the temperature control unit 3 will connect the loop, and the heating unit 4 will work to gradually increase the temperature of the medium. Once the temperature reaches the preset heating limit, the temperature control unit 3 will react immediately and stop heating by disconnecting the connection loop with the heating unit 4, thereby preventing the hot tank body 1 from overheating.

[0062] Furthermore, the temperature control unit 3 includes a mounting component 31 and temperature control switches 32; wherein, there are multiple temperature control switches 32. Each temperature control switch 32 includes a first temperature controller that can be automatically reset and a second temperature controller whose trigger temperature is higher than the first temperature controller and requires manual reset. The first temperature controller, the second temperature controller, and the heating unit are all connected in series in the circuit. Both temperature controllers can disconnect the heating unit. When the first temperature controller, which can be automatically reset, is triggered, for example at a temperature of 105 degrees Celsius, it disconnects the heating unit. When the temperature drops to 80 degrees Celsius, the first temperature controller automatically resets, and the heating unit can operate normally. Even if the first temperature controller fails, at a higher temperature, such as 120 degrees Celsius, the second temperature controller will be triggered. At this time, the second temperature controller will no longer automatically reset, and the machine needs to be repaired. The temperature control switches 32 are preferably KSD301 type temperature control switches 32; each temperature control switch 32 is detachably mounted on the mounting component 31. This embodiment employs multiple temperature control switches 32, designed for detachable mounting on the mounting bracket 31. This provides significant advantages for temperature control of the hot tank body 1, improving both accuracy and flexibility, allowing for various temperature settings and adjustments based on actual needs. Furthermore, it facilitates replacement, upgrades, or repairs of the temperature control switches 32 by users or maintenance personnel, reducing maintenance costs and time. In addition, the configuration of multiple temperature control switches 32 enhances the safety and stability of the hot tank, ensuring reliable temperature control under different operating conditions and extending the service life of the hot tank body 1.

[0063] As a preferred embodiment, such as Figure 2 and Figure 3 As shown, the mounting component 31 includes a mounting plate 311 and two side plates 312, which are respectively fixedly mounted on the two sides of the mounting plate 311; the mounting plate 311 is fixed to the hot tank body 1 by the two side plates 312.

[0064] According to the above technical solution, the mounting component 31 serves as the support structure for the temperature control switch 32. It consists of a mounting plate 311 and two side plates 312. The two side plates 312 are fixedly installed on the two sides of the mounting plate 311 to form a stable frame. This frame is fixed to the appropriate position of the hot tank body 1 by the two side plates 312, ensuring that the temperature control switch 32 can be closely attached to the outer wall of the hot tank body 1 for temperature monitoring. When the temperature of the hot tank body 1 changes, the temperature control switch 32 will open or close according to the preset temperature threshold, thereby realizing the control of the heating unit 4.

[0065] As a preferred embodiment, such as Figure 3As shown, the mounting plate 311 has a mounting slot 3111, the diameter of which is matched with the diameter of the temperature control switch 32. The temperature control switch 32 passes through the mounting slot 3111 and is fixed to the mounting plate 311. According to the above technical solution, the mounting slot 3111 on the mounting plate 311 has a diameter that precisely matches the diameter of the temperature control switch 32, providing a stable mounting position for the temperature control switch 32. During installation, the temperature control switch 32 is fixed to the mounting plate 311 by fasteners (such as screws) through the mounting slot 3111. This not only ensures that the temperature control switch 32 can stably monitor the temperature changes of the hot tank body 1, but also facilitates subsequent maintenance and replacement.

[0066] As a preferred embodiment, such as Figure 2 and Figure 3 As shown, the mounting plate 311 has at least one first mounting hole 3112, and the temperature control switch 32 has at least one second mounting hole 321. Each first mounting hole 3112 and each second mounting hole 321 are correspondingly provided, and the first mounting hole 3112 and the second mounting hole 321 are adapted to each other.

[0067] Wherein, the first mounting hole 3112 and / or the second mounting hole 321 are arc-shaped holes; preferably, in this embodiment, the first mounting hole 3112 is a circular hole and the second mounting hole 321 is an arc-shaped hole.

[0068] According to the above technical solution, at least one first mounting hole 3112 opened on the mounting plate 311 corresponds to at least one second mounting hole 321 opened on the temperature control switch 32, and the diameter or shape of the two are compatible, which provides the temperature control switch 32 with flexible installation and fine-tuning possibilities. In particular, when the second mounting hole 321 is designed as an arc-shaped hole, the temperature control switch 32 is allowed to be adjusted within a certain range of angles on the mounting plate 311 to adapt to different installation requirements or optimize the position of the temperature monitoring point. During installation, the operator can fix the temperature control switch 32 on the mounting plate 311 by passing fasteners (such as screws) through the corresponding first mounting hole 3112 and second mounting hole 321. Due to the existence of the arc-shaped hole, the operator can fine-tune the temperature control switch 32 before fixing to ensure that it can be close to the outer wall of the hot tank at the best angle and position, thereby more accurately monitoring temperature changes. After the temperature control switch 32 is firmly installed on the mounting plate 311, it can work according to the preset temperature threshold to achieve precise control of the heating unit 4.

[0069] On the other hand, such as Figures 6 to 9 As shown, this application also proposes a water supply device, including a housing 5 and a heat exchange assembly 6. The heat exchange assembly 6 is disposed inside the housing 5 and includes a heat exchanger 61. A hot tank with a temperature probe is connected to the heat exchanger 61.

[0070] It also includes a first pipe unit and a second pipe unit, which are disposed inside the housing 5;

[0071] The first pipe unit 71 includes a first pipe 71, a second pipe 72, and a third pipe 73. The first pipe 71 is connected to the drinking water inlet 611. One end of the second pipe 72 is connected to the drinking water outlet 612, and the other end of the second pipe 72 is connected to the heater 9. The heater 9 is connected to the third pipe 73. According to the above technical solution, this embodiment has a drinking water inlet 611, a drinking water outlet 612, a hot water inlet 613, and a hot water outlet 614 on the heat exchanger 61. These interfaces provide the necessary channels for heat exchange between the heat medium and the drinking water. When starting up, the drinking water first enters the heat exchanger 61 through the drinking water inlet 611. Inside the heat exchanger 61, the drinking water exchanges heat with the heat medium that enters through the hot water inlet 613. During this process, the heat medium transfers heat to the drinking water, causing its temperature to gradually rise, achieving a preheating effect, which facilitates the rapid and large-volume supply of drinking hot water. The preheated drinking water then flows out of the heat exchanger 61 through the drinking water outlet 612 and is guided to the heater 9 via the second pipe 72 of the first pipe unit 71 for further heating.

[0072] The second pipeline unit 72 includes a fourth pipeline 81, a fifth pipeline 82, and a sixth pipeline 83. The bottom end of the fourth pipeline 81 is connected to the fifth pipeline 82. Due to water loss caused by heating and evaporation in the heat tank body 1, water needs to be replenished when the liquid level drops to a certain position. Therefore, the fourth pipeline 81 is connected to a water inlet pipe to replenish water to the heat tank body 1. It should be noted that when the heat tank body introduces heat exchange medium into the heat exchanger 61, the valve on the fourth pipeline 81 needs to be closed. The left end of the fifth pipeline 82 is connected to the hot water inlet port 613 of the heat exchanger 61, and the right end of the fifth pipeline 82 is connected to the water outlet 110 of the square tank. The sixth pipeline 83 is connected to the hot water outlet port 614, and the top end of the sixth pipeline 83 is connected to the water inlet 111 of the square tank.

[0073] A valve is installed on the fourth pipe 81; a water pump 84 is installed on the fifth pipe 82 and / or the sixth pipe 83.

[0074] According to the above technical solution, in order to further optimize the utilization of thermal energy and improve the flexibility of the system, this embodiment adds a second pipe unit 72. The second pipe unit 72 consists of a fourth pipe 81, a fifth pipe 82, and a sixth pipe 83, which together form a closed-loop heat exchange medium circulation system. In order to control the flow of the heat exchange medium and regulate the operation of the system, a valve is specially installed on the fourth pipe 81. The valve can be opened or closed as needed to replenish the heat exchange medium in the heat tank body.

[0075] Furthermore, to overcome the resistance that the heat medium may encounter during circulation and ensure its smooth circulation within the system, a water pump 84 is installed on the fifth pipe 82 and / or the sixth pipe 83. The addition of the water pump 84 not only improves operating efficiency but also allows the entire system to adjust its operating status more flexibly under different working conditions. During operation, the heat medium in the heat tank enters the fifth pipe 82 through the fourth pipe 81 (with the valve open), then the valve is closed, and the water pump 84 pushes the heat exchange medium in the heat tank to the heat exchanger 61. Inside the heat exchanger 61, the heat medium exchanges heat with the drinking water, transferring heat to the drinking water and preheating it. The preheated heat medium then returns to the heat tank through the sixth pipe 83, completing one cycle. Through continuous circulation and preheating, the water supply device proposed in this invention can efficiently utilize the thermal energy in the heat medium to provide users with drinking water at a suitable temperature quickly and in large quantities.

[0076] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
