[0021] like Figures 1 to 3As shown, this utility model provides a water storage device for rapidly dispensing hot water, including a main body for storing water, wherein the main body is provided with a water inlet unit, a water outlet unit and a heating unit; specifically, the main body is also provided with a temperature sensing unit for measuring the water temperature inside the main body, and at least one set of water level detection units for detecting the water level inside the main body is provided.

[0022] The main body includes a tank 1, inside which is a cavity 2 for storing hot water, and a top cover 3 is provided on the top of the tank 1; specifically, an insulation shell 4 is provided on the outside of the tank 1 to keep the hot water inside the tank 1 warm, the tank 1 is arranged inside the insulation shell 4, and a bottom plate 5 is provided at the bottom of the insulation shell 4, and the bottom of the tank 1 is fixedly connected to the bottom plate 5 by at least two support members 6.

[0023] The water inlet unit includes a water inlet pipe 7 fixedly mounted on the upper cover plate 3. The water inlet pipe 7 extends upward to the top surface of the upper cover plate 3 and connects to the outside and the inside of the receiving cavity 2. Specifically, the heating unit includes a heating element 8 located on the bottom surface of the tank body 1. A temperature control unit for controlling the heating of the heating element 8 is also fixedly mounted on the bottom surface of the tank body 1. The temperature control unit is electrically connected to the heating element 8 and electrically connected to the power supply line inside the heating element 8. The function of the temperature control unit is to prevent the heating element 8 from burning dry, thus providing protection against dry burning. The temperature control unit is directly connected to the power supply. Since the temperature sensing unit cannot detect whether there is water inside the tank body 1, it cannot prevent dry burning. When the heating element 8 continues to heat and rises to a certain temperature, the temperature control unit controls the heating element 8 to stop working.

[0024] The temperature sensing unit includes a temperature sensor 9 disposed inside the tank 1, and the temperature sensor 9 is inserted and fixed on the upper cover plate 3; specifically, the end of the temperature sensor 9 extends into the receiving cavity 2, and the end of the temperature sensor 9 extends to near the bottom surface of the receiving cavity 2.

[0025] The water level detection unit includes a water level probe assembly inserted and fixed on the upper cover plate 3. The water level probe assembly is fixed on the upper cover plate 3 by bolts. At the same time, the water level probe assembly can also be fixed by any other fixing method that can achieve the same technical effect, such as snap-fit ​​or welding. The end of the water level probe assembly extends into the receiving cavity 2. Specifically, the water level probe assembly includes a first water level probe 10, a second water level probe 11, and a third water level probe 12. The lengths of the first water level probe 10, the second water level probe 11, and the third water level probe 12 are all different. The three water level probes of different lengths are used to detect different water levels in the receiving cavity 2.

[0026] The water outlet unit includes a water outlet pipe 13. The insulation shell 4 is provided with a channel 14 for the water outlet pipe 13 to pass through. One end of the water outlet pipe 13 extends into the receiving cavity 2 through the upper cover plate 3. The end of the water outlet pipe 13 arranged in the receiving cavity 2 extends close to the bottom surface of the receiving cavity 2. Specifically, the other end of the water outlet pipe 13 bends through the channel 14 and extends downward along the channel 14.

[0027] The temperature control unit includes a manual temperature controller 15 and an automatic temperature controller 16. Under normal circumstances, when the temperature of the heating element 8 rises to 140°C and continues to heat for a period of time, the automatic temperature controller 16 controls the heating element 8 to stop working. When the automatic temperature controller 16 malfunctions and cannot control the heating element 8 to stop working at 140°C, the manual temperature controller 15 starts to work. The manual temperature controller 15 controls the heating element 8 to stop working after the temperature of the heating element 8 rises to 170°C and continues to heat for a period of time.

[0028] A sealing cap 17 is provided between the outer edge of the top surface of the tank body 1 and the outer edge of the upper cover plate 3 for sealing.

[0029] It also includes an external water supply system and a water outlet system. The water supply system is connected to the inlet pipe 7 through a water pipe. The water supply system is equipped with a water pump unit for drawing water, such as a water pump or other equivalent structure. The water pump unit is electrically connected to the water level probe assembly. When the water level probe assembly detects the lowest water level in the receiving cavity 2, the water level probe assembly is electrically connected to the water pump unit and sends a signal. The water pump unit starts and delivers water to the receiving cavity 2 until the water level in the receiving cavity 2 rises to the highest water level. The water outlet system includes other equivalent structures such as a faucet. The water outlet system is connected to the end of the water outlet pipe 13 away from the receiving cavity 2. The hot water in the receiving cavity 2 is transported from the water outlet pipe 13 to the water outlet system by utilizing the water level difference or the gravity of the water itself.

[0030] Temperature sensor 9 is electrically connected to the internal control board via a lead wire. The control board is electrically connected to the heating element 8 via a lead wire. After the user sets the desired heating temperature through the control board, the control board automatically determines whether to start the heating element 8 for heating by sensing the water temperature transmitted by temperature sensor 9, thereby achieving the corresponding temperature control effect.

[0031] In this invention, the electrical induction control connection between the pumping unit and the water level probe assembly, the electrical connection between the temperature sensor 9 and the control board, the electrical connection between the control board and the heating element 8, the internal electrical working principle of the control board, the electrical control connection between the temperature control unit and the heating element 8, and the water discharge by utilizing the water level difference or the gravity of the water are all technical means commonly used and easily conceived by those skilled in the art, and therefore will not be elaborated upon further.

[0032] The working principle of this utility model is as follows: The water pump unit in the water supply system starts, pumping cold water into the receiving cavity 2 through the inlet pipe 7. Once the water level probe component detects that the water level in the receiving cavity 2 has reached its maximum, the water level probe component sends a control signal to the water pump unit, causing the water pump unit to stop working. The temperature sensor 9 senses the water temperature in the receiving cavity 2 and transmits the sensed temperature electrically to the control board via a lead wire. The control board compares this temperature with the user-set temperature and automatically determines whether the heating element 8 needs to be activated for heating. The control board then controls the heating element 8 to start heating via the lead wire, thus heating the cold water in the receiving cavity 2. The heating element 8 stops heating when the temperature sensor 9 senses that the water temperature in the containment cavity 2 has reached the same temperature as the user-set temperature. When there is no water in the containment cavity 2, the temperature sensor 9 cannot detect the water temperature, and the heating element 8 will burn dry. When the temperature of the heating element 8 rises to 140°C and works for a period of time, the automatic thermostat 16 controls the heating element 8 to stop working. When the automatic thermostat 16 malfunctions and cannot control the heating element 8 to stop working at 140°C, the manual thermostat 15 starts working. The manual thermostat 15 controls the heating element 8 to stop working after the temperature of the heating element 8 rises to 170°C and continues to heat for a period of time. When the user turns on the water outlet system, the hot water in the receiving chamber 2 flows out from the outlet pipe 13 by utilizing the water level difference or the water's own gravity. Finally, the hot water is supplied to the user through the water outlet system connected to the end of the outlet pipe 13. The water level in the receiving chamber 2 drops until it reaches the lowest water level that the water level probe assembly can detect. Then, the water level probe assembly sends a control signal to the pumping unit to continue pumping. The above principle is repeated to ensure that there is always hot water available for the user in the receiving chamber 2.

[0033] The advantages of this utility model are as follows: by setting a temperature sensing unit and a water level detection unit inside the tank 1, the temperature sensing unit electrically controls the temperature control unit, and the temperature control unit controls the heating element 8 to heat up, so that the water temperature in the tank 1 is always kept at a certain temperature, saving the time required to preheat the water in the tank 1. The water level detection unit controls the water level in the tank 1 to always meet the user's needs, avoiding the situation of insufficient water or excessive water overflow, thus improving the user's experience.
