Description

Technical Field

[0001] This utility model relates to the technical field of hot water supply equipment, and in particular to an instant hot water dispenser, specifically an instant hot water supply device suitable for fast food trucks. Background Technology

[0002] In scenarios such as military logistics support, outdoor operations, and emergency rescue, equipment capable of providing large quantities of hot water anytime and anywhere is often needed to ensure personnel's food and drinking water needs. Traditional hot water supply systems have many shortcomings:

[0003] 1. Ordinary electric water heaters cannot work properly in environments with unstable power supply or lack of mains power access, such as remote mountainous areas and plateau wilderness areas, and cannot meet the demand for instant hot water.

[0004] 2. While conventional fuel-fired water heaters have solved some of the electricity dependence problem, they generally suffer from drawbacks such as large size, low thermal efficiency, and slow heating. They are not suitable for the limited space inside container cabins, and their high energy consumption is not conducive to long-term logistical support operations.

[0005] 3. Existing technologies lack adequate design for water heaters in high-altitude environments. In high-altitude areas, problems such as reduced air pressure, thin air, incomplete combustion, and obstructed heat transfer frequently occur, making it difficult for water heaters to operate normally and produce a stable supply of hot water, which seriously affects the smooth progress of related tasks.

[0006] 4. Some fixed-installation water dispensers are bulky and heavy, making them inconvenient to move and difficult to meet the needs of vehicle-mounted mobility.

[0007] This application aims to overcome the shortcomings of these existing technologies and provide an efficient, convenient, and versatile vehicle-mounted water dispenser. Utility Model Content

[0008] In order to solve a series of problems of traditional hot water supply devices, such as unstable power supply or inability to work properly when there is no mains power access, large size of fuel-fired water heaters, low thermal efficiency, slow heating, high energy consumption, large space requirements, difficulty in normal operation in high-altitude areas, and inconvenience in moving, this utility model provides an instant hot water supply device suitable for food trucks.

[0009] This utility model provides an instant hot water supply device suitable for fast food trucks, including a housing with a vertical burner inside. A hot water tank is located above the burner, and the top of the hot water tank has an air outlet. A water replenishment tank is located on one side of the hot water tank, and a valve is located on the top of the water replenishment tank. The bottom of the water replenishment tank is connected to a water inlet via an inlet pipe, and a first water pump is installed on the inlet pipe. The bottom outlet of the water replenishment tank is connected to the hot water tank via a second pipe, and a first pipe extending into the hot water tank is connected to the second pipe. A circulation pump is installed on the first pipe. The bottom outlet of the hot water tank is connected to a hot water outlet via a hot water outlet pipe, and a second water pump is installed on the hot water outlet pipe. The hot water outlet pipe is connected to a coil installed inside the water replenishment tank via a third pipe, and a third water pump is installed on the third pipe. The outlet of the coil is connected to a warm water outlet via a warm water outlet pipe.

[0010] During implementation, the enclosure, constructed from high-strength, lightweight alloy materials, ensures overall structural stability while reducing equipment weight for easy vehicle transport. The enclosure employs a modular structure for convenient installation, disassembly, and maintenance of components. Inside the enclosure is a vertical burner that uses diesel fuel, featuring rapid temperature rise, small size, light weight, and low energy consumption. It can operate normally at altitudes up to 5500 meters. The burner's flue outlet is connected to the top grille of the enclosure for flue gas emission.

[0011] A hot water tank is located above the vertical burner. The top of the hot water tank has an air outlet that extends from the top of the tank to discharge water vapor from the hot water tank.

[0012] The top of the tank is equipped with a pressure sensor, pressure gauge, pressure relief valve, and safety valve connected to the hot water tank. These are used to control the pressure inside the hot water tank. When the pressure exceeds the set value, the pressure relief valve automatically opens and releases the gas pressure to prevent the system pressure from becoming too high and to protect the equipment and pipelines from damage due to overpressure. When an abnormally high pressure is detected, reaching or exceeding the safety valve's opening pressure, the safety valve quickly opens and discharges the medium to protect the equipment and personnel and prevent serious accidents such as explosions.

[0013] The front of the tank is equipped with a level gauge that connects to the hot water tank; the top of the tank is equipped with a level sensor that extends into the hot water tank. The level sensor collects the level information and transmits it to the control system. The control system is installed on the front of the tank and has a door and lock at the control system operation point. The control system sends a command to the first water pump to stop the water intake and realize automatic water replenishment.

[0014] A water replenishment tank is located on one side of the hot water tank. A valve is installed on the top of the water replenishment tank to control the pressure inside and ensure that the tank is filled with water. The bottom of the water replenishment tank is connected to the water inlet via an inlet pipe, which is equipped with a first water pump. The bottom outlet of the water replenishment tank is connected to the hot water tank via a second pipe, which is connected to a first pipe extending into the hot water tank. A circulation pump is installed on the first pipe. The bottom outlet of the hot water tank is connected to the hot water outlet via a hot water outlet pipe, which is equipped with a second water pump. The hot water outlet pipe is connected to a coil installed inside the water replenishment tank via a third pipe. The coil is made of copper tubing and is coiled inside the tank. A third water pump is installed on the third pipe. The outlet of the coil is connected to the warm water outlet via a warm water outlet pipe. The water inlet, hot water outlet, and warm water outlet are all located on the front of the tank.

[0015] When in use, this device can be installed inside a container cabin for logistical support scenarios.

[0016] The first water pump is turned on, and water enters the water supply tank through the inlet pipe, then through the second pipe and the first pipe, and enters the hot water tank through the circulation pump to complete the water supply; the vertical burner heats the water in the hot water tank.

[0017] When hot water is needed, the second water pump is turned on, and hot water is discharged from the hot water outlet pipe to provide hot water supply.

[0018] When using warm water, the boiled hot water enters the coil through the third pipe and the third water pump. In the coil, it exchanges heat with the cold water in the water supply tank to achieve cooling. Finally, it is discharged from the warm water outlet pipe to achieve warm water supply. At the same time, the cold water in the water supply tank is preheated by the coil, which raises its temperature before entering the hot water tank, saving fuel used by the vertical burner, improving energy efficiency, and ensuring that 500L of hot water at a temperature of not less than 50℃ can be stably provided for 1 hour.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model provides an instant hot water supply device suitable for food trucks. Through an innovative connection and collaborative working mechanism with the hot water tank and the replenishment water tank, it achieves automatic water replenishment, precise temperature control, and energy recovery and utilization, further improving the overall performance and practicality of the equipment. This device can provide 500L of hot water at a temperature of not less than 50℃ per hour, meeting the hot water needs of a large number of people in special environments. Attached Figure Description

Detailed Implementation

[0028] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0029] An instant hot water supply device suitable for food trucks, such as Figures 1-4 As shown, the implementation includes a housing 7, which is made of high-strength, lightweight alloy material. This ensures the overall structural stability while reducing the weight of the equipment, facilitating vehicle transport. The housing 7 adopts a modular structure, simplifying the installation, disassembly, and maintenance of each component. A vertical burner 4 is installed inside the housing 7. The vertical burner 4 uses diesel fuel, features rapid temperature rise, small size, light weight, and low energy consumption, and can operate normally in high-altitude areas up to 5500 meters. The flue outlet 8 of the vertical burner 4 is connected to the top grille of the housing 7 for flue gas emission.

[0030] A hot water tank 16 is provided above the vertical burner 4. The top of the hot water tank 16 has an air outlet 12 that is connected to the air. The air outlet 12 extends out from the top surface of the housing 7 and is used to discharge water vapor from the hot water tank 16.

[0031] The top of the housing 7 is equipped with a pressure sensor 13, a pressure gauge 11, a pressure relief valve 9, and a safety valve 14 connected to the hot water tank 16. These are used to control the pressure inside the hot water tank 16. The pressure sensor 13 monitors the pressure inside the system in real time. When the pressure exceeds the set upper limit, the safety valve 14 is triggered to open and release pressure. The pressure gauge allows operators to directly read the system pressure so as to keep track of the equipment's operating status. When the pressure exceeds the set value, the pressure relief valve 9 automatically opens and releases the gas pressure to prevent the system pressure from being too high and to protect the equipment and pipelines from damage due to overpressure. When an abnormally high pressure is detected, reaching or exceeding the safety valve's tripping pressure, the safety valve 14 quickly opens and discharges the medium to protect the equipment and personnel and prevent serious accidents such as explosions.

[0032] The front of the housing 7 is equipped with a level gauge 1 that connects to the hot water tank 16; the top of the housing 7 is equipped with a level sensor 10 that extends into the hot water tank 16. The level sensor 10 collects the level information and transmits it to the control system 2 (only the location of the control system 2 is shown in the figure). The control system 2 is installed on the front of the housing 7 and has a door and a door lock 3 at the control system operation point. The control system 2 sends a command to the first water pump 19 to stop the water intake and realize automatic water replenishment.

[0033] A temperature sensor is installed inside the hot water tank 16 to accurately measure the hot water outlet temperature. When the temperature does not reach the set standard (such as 50℃), the control system adjusts the fuel supply of the vertical burner 4 to increase the firepower and ensure that the outlet water temperature is stable and meets the requirements.

[0034] A water replenishment tank 17 is provided on one side of the boiling water tank 16. A valve (not shown in the figure in this embodiment) is located on the top of the water replenishment tank 17 to control the pressure inside the tank and ensure water is supplied. The bottom of the water replenishment tank 17 is connected to the water inlet 5 via an inlet pipe L4. A first water pump 19 is installed on the inlet pipe L4. The bottom outlet of the water replenishment tank 17 is connected to the boiling water tank 16 via a second pipe L2. A first pipe L1, extending into the boiling water tank 16, is connected to the second pipe L2. A circulation pump 22 is installed on the first pipe L1. The bottom outlet of the hot water tank 16 is connected to the hot water outlet 15 via the hot water outlet pipe L5. A second water pump 20 is installed on the hot water outlet pipe L5. The hot water outlet pipe L5 is connected to the coil 18 installed in the water supply tank 17 via the third pipe L3. The coil 18 is made of copper pipe and is coiled inside the water supply tank 17. A third water pump 21 is installed on the third pipe L3. The outlet of the coil 18 is connected to the warm water outlet 6 via the warm water outlet pipe L6. The inlet 5, the hot water outlet 15 and the warm water outlet 6 are all located on the front of the tank body 7.

[0035] When in use, this device can be installed inside a container cabin for logistical support scenarios.

[0036] The first water pump 19 is turned on, and water enters the water supply tank 17 through the water inlet 5 and the water inlet pipe L4. Then, it enters the hot water tank 16 through the second pipe L2 and the first pipe L1 and the circulating pump 22 to complete the water supply. The vertical burner 4 heats the water in the hot water tank 16.

[0037] like Figure 3 As shown, when hot water is used, the second water pump 20 is turned on, and hot water is discharged from the hot water outlet 15 through the hot water outlet pipe L5 to achieve hot water supply.

[0038] like Figure 4 As shown, when using warm water, the boiled hot water enters the coil 18 through the third pipe L3 via the third water pump 21. In the coil 18, it exchanges heat with the cold water in the water supply tank 17 to achieve cooling. Finally, it is discharged from the warm water outlet 6 through the warm water outlet pipe L6 to achieve warm water supply. At the same time, the cold water in the water supply tank 17 is preheated by the coil 18, which raises its temperature before entering the hot water tank 16, saving the fuel required by the vertical burner 4, improving energy efficiency, and ensuring that 500L of hot water with a temperature of not less than 50℃ can be stably provided for 1 hour.
