[0002] In the field of drinking water equipment, the heat tank, as its core component, plays a crucial role. However, in the traditional heat tank structure, the heating element and control circuit are often fixedly installed, lacking a detection mechanism for the inclined state of the heat tank. In actual use, if the heat tank is inclined due to improper operation or accidental situations, the heating device may not respond in time and cut off the power supply, thereby causing a series of safety hazards. The inclination of the heat tank can cause uneven distribution of the heat exchange medium inside the heat tank, leading to local heating / overheating. This not only accelerates the damage to the internal structure of the heat tank, but also can cause burns or fire and other serious consequences. In addition, the inclined heat tank can also affect the heat exchange efficiency, reduce the heating speed and quality of the drinking water, and thus affect the normal use experience of the user.

DETAILED DESCRIPTION

[0042] With reference to the accompanying drawings: the technical solutions in the embodiments of the present application will be described clearly and completely, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor belong to the scope of protection of the present application.

[0043] The present embodiment proposes a heat tank, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 , comprising a heat tank body 1, a hollow cavity is formed in the heat tank body 1, and the cavity is used for storing heat exchange medium; the heat exchange medium is used for heat exchange of drinking water after being heated, so as to quickly heat the drinking water to meet the demand of the drinking water equipment for hot water.

[0044] A detection device and a heating device, the detection device is used for connecting with the heating device, and the heating device is used for heating the heat exchange medium; the detection device can detect the state of the heat tank body 1, and when the heat tank body 1 is in an inclined state, the detection device controls the heating device to stop working.

[0045] According to the above technical solution, the heat tank body 1 is internally provided with a hollow cavity, and the cavity is used for storing heat exchange medium such as water, heat conducting oil or other high-efficiency heat conducting liquid, which is heated to a certain temperature under the action of the heating device to heat exchange the drinking water. The detection device can continuously monitor the state of the heat tank body 1, and when the detection device detects that the heat tank body 1 is in an inclined state, the circuit connected with the heating device will be quickly cut off, the heating device stops working, and the heat exchange medium in the cavity is no longer heated, which can effectively prevent the heat tank from continuing to heat when it is inclined or tilted, thereby avoiding the safety hazards such as local overheating, structural damage and even fire.

[0046] Among them, the number of detection devices is one or more, and the detection devices are installed on the top, bottom or side wall of the heat tank body 1. One or more detection devices installed on the top, bottom or side wall of the heat tank body 1 can quickly cut off the circuit connected with the heating device when the heat tank body 1 is detected to be inclined, so that the heating device stops working immediately, effectively preventing the heat exchange medium from continuing to heat in an unstable state; in addition, the intelligent linkage of the detection device and the heating device ensures that the heat tank body can quickly enter the safety protection mode in the inclined abnormal state, which provides a solid guarantee for the stable operation of the heat tank system, and also improves the overall safety and reliability of the system.

[0047] In an embodiment, the detection device is a sensor and a controller, the controller is connected with the sensor, and the controller is connected with the heating device; wherein the sensor can be used to measure the angle of the heat tank body 1 relative to the plane to achieve the purpose of monitoring the state of the heat tank body 1; the sensor can adopt an inclination sensor, such as a dynamic inclination sensor, a single-axis inclination sensor, a double-axis inclination sensor, and a three-axis inclination sensor, etc.

[0048] The sensor is installed inside and / or outside the heat tank body 1, of course, the sensor can also be installed at any position in the shell 5 or the water supply device. At the same time, the number of sensors is not limited to one, and multiple sensors can also be installed. Through the installation of multiple sensors, comprehensive monitoring of the heat tank body 1 and its related system can be achieved, multiple sensors can provide redundant data, and through the comparison and verification of these data, the accuracy and reliability of the monitoring can be further improved. For example, when the data of a certain sensor is significantly different from that of other sensors, maintenance or replacement can be carried out in time, and multi-point monitoring helps to discover potential safety hazards in time, thereby avoiding excessive heating.

[0049] In the present embodiment, the tilting power-off function of the heat tank body 1 relies on the cooperative work of the sensor, the controller and the heating device. The sensor is installed inside or outside the heat tank body 1 and is responsible for capturing the tilting state of the heat tank in real time. Once the sensor detects that the heat tank body 1 is tilted, it will immediately send this signal to the controller connected thereto. The controller, preferably a single-chip microcomputer controller, will quickly judge and react by cutting off the connection with the heating device to stop the heating process. This design not only improves the safety of the heat tank, but also ensures that users can be reliably protected in various use scenarios.

[0050] In an embodiment, as shown in Figure 1 and Figure 2 , the detection device is a first detector 21; the first detector 21 comprises a first cylinder 211, a first conductive part 212, a second conductive part 213 and a conductive liquid 214; the first cylinder 211 is in a hollow and sealed structure, the conductive liquid 214 is preferably mercury, the conductive liquid 214 is filled in the first cylinder 211, the first conductive part 212 and the second conductive part 213 are arranged in the first cylinder 211 in a spaced manner, and the first conductive part 212 and the second conductive part 213 are connected with a circuit on-off detection module; when the circuit on-off detection module detects that the circuit is disconnected, the heating device stops working; when the heat tank body 1 is in a horizontal state, the conductive liquid 214 is in contact with the first conductive part 212 and the second conductive part 213 at the same time, and the circuit is in communication; when the heat tank body 1 is in a tilted state, the conductive liquid 214 is at least out of contact with the first conductive part 212 or the second conductive part 213, and the circuit is disconnected.

[0051] According to the technical solution, the tilting power-off function of the hot pot body 1 is realized by the first detector 21. The first detector 21 internally comprises a hollow sealed first cylinder 211, the first cylinder 211 is filled with conductive liquid 214, and the first cylinder 211 is provided with a first conductive part 212 and a second conductive part 213 at intervals. When the hot pot body 1 is in a horizontal state, the conductive liquid 214 is uniformly distributed in the first cylinder 211 due to the action of gravity, and is in contact with the first conductive part 212 and the second conductive part 213 at the same time under normal conditions. This contact state allows the circuit to be connected, and the heating device works normally. However, once the hot pot body 1 is tilted, the distribution of the conductive liquid 214 in the first cylinder 211 will change. Due to the action of gravity, the conductive liquid 214 will deviate to one side of the first cylinder 211, resulting in contact with only one of the first conductive part 212 or the second conductive part 213. Alternatively, the conductive liquid 214 does not contact the first conductive part 212 and the second conductive part 213. This change in contact state causes the circuit to be disconnected, realizing the function of tilting power-off, ensuring the safety of the hot pot in the tilted state, and having simple structure, low cost, easy implementation and maintenance.

[0052] In one embodiment, as Figure 3 and Figure 4 described, the detection device is a second detector 22; the second detector 22 comprises a second cylinder 221, a third conductive part 222, a fourth conductive part 223 and a conductive ball 224, the third conductive part 222, the fourth conductive part 223 and the conductive ball 224 are arranged in the second cylinder 221; wherein the third conductive part 222 and the fourth conductive part 223 are arranged in a V shape and do not contact each other; when the hot pot body 1 is in a horizontal state, the conductive ball 224 is in contact with the third conductive part 222 and the fourth conductive part 223 at the same time, and the circuit is connected; when the hot pot body 1 is in a tilted state, the conductive ball 224 is at least in contact with the third conductive part 222 or the fourth conductive part 223, and the circuit is disconnected.

[0053] In this embodiment, the tilt detection function of the heat tank body 1 can be implemented by the second detector 22. The second detector 22 is internally provided with a second cylinder 221, and the second cylinder 221 is internally provided with a third conductive member 222, a fourth conductive member 223, and a conductive ball 224. These components together constitute a sensitive tilt detection mechanism. When the heat tank body 1 is in a horizontal state, the conductive ball 224 is stably positioned between the third conductive member 222 and the fourth conductive member 223 due to the action of gravity, and at the same time, it maintains contact with both, ensuring the continuity of the circuit, so that the heating device connected thereto can work normally to provide the required heat for the heat exchange medium. However, when the heat tank body 1 is tilted, the position of the conductive ball 224 in the second cylinder 221 will also change accordingly. Due to the action of gravity, the conductive ball 224 will roll to one side of the second cylinder 221, causing it to only maintain contact with one of the third conductive member 222 or the fourth conductive member 223, and lose contact with the other. This change in contact state will immediately cause the circuit to be disconnected, cutting off the power supply to the heating device, to prevent potential safety hazards that may occur when heating in a tilted state. The design of the second detector 22 not only improves the safety of the heat tank, but also has a simple and clear working principle, easy to implement and maintain, providing reliable protection for the tilt power-off function of the heat tank.

[0054] It should be noted that both the first detector 21 and the second detector 22 need to be installed horizontally on the heat tank body 1 or the drinking water supply device as required to maintain the continuity of the circuit.

[0055] Further, the conductive ball 224 is a metal iron ball. The metal iron ball has good conductivity, which can ensure that when the heat tank body 1 is in a horizontal state, it stably forms a conductive path with the third conductive member 222 and the fourth conductive member 223, and at the same time, it reliably disconnects the circuit when tilted, realizing the safety protection mechanism of tilt power-off.

[0056] As a preferred embodiment, the heating device includes a heating pipe that extends into the heat tank body 1 for heating the heat exchange medium in the heat tank body 1. The heating pipe extends into the heat tank body 1 and directly contacts the heat exchange medium in the inner cavity. When the circuit is connected, the heating pipe can generate heat and transfer heat to the surrounding heat exchange medium, thereby realizing the heating process.

[0057] In one possible implementation, the heating device is not limited to a heating pipe, but can also use an electromagnetic coil. When alternating current or direct current passes through the electromagnetic coil, a changing electromagnetic field is generated. This changing electromagnetic field forms magnetic lines of force in the space around it. These magnetic lines of force pass through the heated object, such as the heat exchange medium inside the heat tank body 1. Due to electromagnetic induction, the heated object generates eddy currents in the changing magnetic field. The eddy currents flow inside the object and generate heat, thereby heating the heat exchange medium inside the heat tank body 1.

[0058] On the other hand, such as Figures 5 to 8 As shown, this application also proposes a water supply device, characterized in that it includes a housing 5 and a heat exchange component 6, wherein the heat exchange component 6 is disposed inside the housing 5;

[0059] Heat exchange assembly 6 includes heat exchanger 61;

[0060] It also includes the aforementioned hot tank; the hot tank is connected to heat exchanger 61.

[0061] Furthermore, the heat exchanger 61 is provided with a first flow channel, a drinking water inlet 611, a drinking water outlet 612, a second flow channel, a hot water inlet 613, and a hot water outlet 614. The first flow channel is connected to the drinking water inlet 611 and the drinking water outlet 612, and the second flow channel is connected to the hot water inlet 613 and the hot water outlet 614. The second flow channel is not connected to the first flow channel. When the heat exchange medium is in the second flow channel, it can exchange heat with the drinking water in the first flow channel to achieve the purpose of heating the drinking water, so as to provide hot water quickly and in large quantities.

[0062] Furthermore, it also includes a first pipe unit 71, which is disposed within the housing 5. 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 interface 611, one end of the second pipe 72 is connected to the drinking water outlet interface 612, and the other end of the second pipe 72 is connected to a heater 9, which is connected to the third pipe 73. Upon startup, drinking water first enters the heat exchanger 61 through the drinking water inlet interface 611. Inside the heat exchanger 61, the drinking water exchanges heat with the heat exchange medium entering through the hot water inlet interface 613. During this process, the heat exchange medium transfers heat to the drinking water, gradually increasing its temperature, achieving a preheating / heat exchange effect, facilitating the rapid and large-volume supply of hot drinking water. The heat-exchanged drinking water then flows out of the heat exchanger 61 through the drinking water outlet interface 612 and is guided to the heater 9 via the second pipe 72 of the first pipe unit 71 for further heating.

[0063] Further, the second pipeline 72 unit is further included, the second pipeline 72 unit includes the fourth pipeline 81, the fifth pipeline 82 and the sixth pipeline 83, the fourth pipeline 81 is communicated with the fifth pipeline 82, and the valve is arranged on the fourth pipeline 81;One end of the fifth pipeline 82 is communicated with the square tank water outlet 110, the other end of the fifth pipeline 82 is communicated with the heat exchange water inlet interface 613 of the heat exchanger 61, one end of the sixth pipeline 83 is connected on the heat exchange water outlet interface 614, and the other end of the sixth pipeline 83 is communicated with the square tank water inlet 111;Because the heat exchange medium in the heat tank body 1 is heated and evaporated, there is loss, and the liquid level drops to a certain position, so it needs to be supplemented, and therefore the fourth pipeline 81 is connected with the water inlet pipe for supplementing the heat exchange medium for the heat tank body 1;It should be noted that when the heat tank body 1 is connected with the heat exchange medium to the heat exchanger 61, the valve on the fourth pipeline 81 needs to be closed, the left end of the fifth pipeline 82 is communicated with the heat exchange water inlet interface 613 of the heat exchanger 61, the right end of the fifth pipeline 82 is communicated with the square tank water outlet 110, the sixth pipeline 83 is connected on the heat exchange water outlet interface 614, and the top end of the sixth pipeline 83 is communicated with the square tank water inlet 111.

[0064] In order to overcome the resistance that the heat exchange medium may encounter in the circulation process, and ensure that the heat exchange medium can circulate smoothly in the system, a water pump 84 is further arranged on the fifth pipeline 82 and / or the sixth pipeline 83, the addition of the water pump 84 not only improves the operation efficiency, but also enables the entire system to be more flexible in adjusting the operation state when facing different working conditions.In work, the heat medium in the heat tank body 1 enters the fifth pipeline 82 through the fourth pipeline 81 (in the state that the valve is opened), then the valve is closed, and the heat exchange medium of the heat tank body 1 is pushed by the water pump 84 to flow into the heat exchanger 61, in the heat exchanger 61, the heat exchange medium exchanges heat with the drinking water, transfers heat to the drinking water and preheats it, and then the preheated heat exchange medium returns to the heat tank body 1 through the sixth pipeline 83, to complete a circulation period. Through continuous circulation and preheating, the water supply device proposed in the application can efficiently utilize the heat energy in the heat medium, and quickly and massively provide the user with drinking water with a suitable temperature.

[0065] The above only discloses the preferred embodiments of the application, and of course cannot limit the scope of the application, so the equivalent changes made according to the claims of the application still fall within the scope of the application.
