Description

Technical Field

[0001] This invention belongs to the field of airborne living facilities, specifically relating to an airborne intelligent drinking water system for kitchens and its control method. Background Technology

[0002] Existing airborne kitchens are generally equipped with electric water heaters and drinking water systems, but these systems often lack automatic water filling / draining functions or corresponding safety measures. This requires significant time for operators and maintenance personnel, causing inconvenience to users. Furthermore, the systems cannot collect residual clean water from the water heaters for reuse, hindering water conservation. Incomplete drainage can lead to ice blockage at low temperatures.

[0003] Therefore, how to solve the problems of automatic filling / draining of drinking water in airborne kitchens and water conservation has become an urgent issue to be addressed in this field. Summary of the Invention

[0004] This invention provides an intelligent drinking water system for airborne kitchens and its control method, aiming to solve the problems of inconvenient filling / draining, low efficiency, and insufficient water conservation in existing airborne kitchen drinking water systems. The intelligent drinking water system of this invention can automatically control the filling / draining of electric water heaters, simplifying the operation steps for crew members when using water, accelerating the drainage speed, and saving valuable maintenance time for crew members. It also collects residual water from the electric water heater into a clean water tank, thus saving water. Furthermore, this system also prevents system ice blockage under low-temperature conditions after drainage.

[0005] Technical solution: This invention provides an airborne intelligent drinking water system for kitchens, the system comprising, from top to bottom, an electric water heater, a water supply / drainage assembly, a clean water tank, and a controller; The water supply / drainage assembly connects the electric water heater and the clean water tank through water supply / drainage pipes. The controller controls the water supply / drainage assembly to automatically replenish water to the electric water heater and to automatically drain water from the electric water heater to the clean water tank.

[0006] Furthermore, the electric water heater is equipped with a full liquid level sensor, an empty liquid level sensor, and a temperature sensor to detect the liquid level and hot water temperature, and ultimately transmit the temperature and liquid level signals of the electric water heater to the controller; a liquid level sensor is installed inside the clean water tank. The controller, as a logic control unit, is connected to the full liquid level sensor, the clean water tank level sensor, and the water supply / drainage components to collect and process information, make logical judgments, and perform control. A full liquid level sensor is used to detect whether an electric water heater is full. An empty liquid level sensor is used to detect whether an electric water heater is emptied. The water tank level sensor is used to detect the water level in the water tank.

[0007] Furthermore, the water supply / drainage components include electrically controlled valves and water pumps; The water pump is controlled by a controller to rotate in both directions, providing power for water supply and drainage. The electric valve is controlled by a controller to open or close, and is used to shut off or open the water supply / drainage pipeline.

[0008] Furthermore, after the system is powered on, the controller detects that the system meets the automatic water filling conditions, and the controller controls the water supply / drainage components to automatically replenish the electric water heater to full capacity; When the controller detects a drainage command, it controls the water supply / drainage components to automatically drain the water from the electric water heater into the clean water tank.

[0009] Furthermore, the electric water heater includes: a front panel, a faucet 8, a water tank 5, a base 6, a solenoid valve 1, a temperature sensor 2, a full liquid level sensor 3, an empty liquid level sensor, a drain handle 10, and a drain valve 7. The front panel has a control panel at the top and a faucet in the middle. The water tank 5 is located at the rear of the front panel and is mounted on the base 6. A temperature sensor 2 and a full level sensor 3 are installed on the top of the water tank. An empty level sensor is installed at the bottom of the water tank 5. The water tank 5 is connected to the faucet via a solenoid valve. A drain valve 7 is connected to the bottom of the water tank 5. The drain handle 10 controls the opening and closing of the drain valve 7 for manual drainage in case of system failure.

[0010] The present invention also provides a control method for an airborne kitchen intelligent drinking water system, comprising the following steps: S1. After the system is powered on, the controller collects the liquid level from the water tank level sensor and the full liquid level sensor from the electric water heater. S2. When the automatic water filling conditions are met, the controller will automatically open the solenoid valve of the electric water heater and the electric control valve of the water supply / drainage component, start the water pump to rotate in the forward direction, and the system will start to automatically fill with water. S3. When the conditions for stopping water supply are met, the controller shuts off the solenoid valve of the electric water heater, the electric control valve of the water supply / drainage component, and the water pump, and the system completes automatic water supply. S4. When the automatic drainage conditions are met, the controller automatically opens the solenoid valve of the electric water heater and the electric control valve of the supply / drainage component, starts the water pump to reverse, and the system begins to drain automatically. S5. When the drainage completion condition is met, the controller closes the solenoid valve of the electric water heater, the electric control valve of the supply / drainage component, and the water pump, and the system completes automatic drainage.

[0011] Furthermore, the automatic water filling conditions are: the controller determines that the water tank level sensor signal is not empty, and the controller determines that the full water level sensor signal is not full.

[0012] Furthermore, the conditions for stopping water addition are: the controller determines that the full liquid level sensor signal indicates that the electric water heater is full, or the water pump has been running continuously for more than the maximum set time T1.

[0013] Furthermore, the automatic drainage conditions are as follows: the controller receives a drainage command from the electric water heater, and the controller determines that the water level sensor signal in the clean water tank indicates that the clean water tank is not full.

[0014] Furthermore, the drainage completion condition is: the controller determines that the water level sensor signal indicates that the electric water heater is empty, or the water pump has been running continuously for more than the maximum set time T2.

[0015] Beneficial effects: This invention provides an airborne intelligent drinking water system for kitchens and its control method. The controller collects signals from the full-level, empty-level, and clear-water-tank level sensors of the electric water heater, and controls the filling / draining components to rotate forward to automatically fill the system. The controller also collects drainage signals from the electric water heater, and controls the filling / draining components to rotate in reverse to automatically drain the system. This process collects remaining water from the electric water heater into the clear-water tank, achieving water conservation. Furthermore, the system's drainage function helps prevent ice blockage in low-temperature conditions. The system is easy to operate and offers advantages such as automatic water filling, automatic drainage, and water conservation, demonstrating good practical application value and promising prospects.

[0021] The electric water heater tank 5 is mounted on the base 6, and the tank is equipped with a temperature sensor 2, a liquid level sensor 3, and a pressure relief assembly 4. The tank 5 contains an electric heater and a liquid level sensor, and a drain valve 7 is connected to its bottom. A drain handle 10 at the front bottom of the electric water heater controls the opening and closing of the drain valve 7.

[0022] The electric water heater 20 has a control panel 9 above the faucet 8 on the front side. The water tank 5 is connected to the faucet 8 via a solenoid valve 1 on the side near the control panel 9.

[0023] The electric water heater 20 is surrounded by an outer wall panel 13.

[0024] The bottom of the electric water heater 20 is connected to the tray 11.

[0025] The drain outlet 12 at the rear of the electric water heater 20 is connected to the water supply / drainage assembly 40 via the water supply / drainage pipe 70.

[0026] The water supply / drainage assembly 40 is connected to the clean water tank 50 via the water supply / drainage pipe 70.

[0027] The water supply / drainage assembly 40 includes an electrically controlled valve 41 and a water pump 42, which are arranged vertically to prevent water from accumulating during drainage.

[0028] The controller 30, as a logic control unit, is connected to the control panel 9, full liquid level sensor 3, empty liquid level sensor, clean water tank liquid level sensor 60, and water supply / drainage assembly 40 of the electric water heater 20 to collect and process information, make logical judgments, and control the system.

[0029] After the controller 30 collects the drainage input signal on the control panel 9 of the electric water heater 20, it controls the water supply and drainage component 40 to reverse to drain water from the electric water heater when the automatic drainage conditions are met.

[0030] This invention also provides a control method for an airborne kitchen intelligent drinking water system, such as... Figure 4 As shown, it includes the following steps: S1. After the system is powered on, the controller collects the liquid level from the water tank level sensor and the full liquid level sensor from the electric water heater. S2. When the automatic water filling conditions are met, the controller will automatically open the solenoid valve of the electric water heater and the electric control valve of the water supply / drainage component, start the water pump to rotate in the forward direction, and the system will start to automatically fill with water. S3. When the conditions for stopping water supply are met, the controller shuts off the solenoid valve of the electric water heater, the electric control valve of the water supply / drainage component, and the water pump, and the system completes automatic water supply. S4. When the automatic drainage conditions are met, the controller automatically opens the solenoid valve of the electric water heater and the electric control valve of the supply / drainage component, starts the water pump to reverse, and the system begins to drain automatically. S5. When the drainage completion condition is met, the controller closes the solenoid valve of the electric water heater, the electric control valve of the supply / drainage component, and the water pump, and the system completes automatic drainage.

[0031] The automatic water filling condition is: the controller determines that the water tank level sensor signal is not empty, and the controller determines that the full water level sensor signal is not full.

[0032] Water filling stops when the controller determines that the water level sensor signal indicates the water heater is full, or the water pump has been running for more than the maximum set time T1.

[0033] Automatic drainage conditions: The controller receives a drainage command from the electric water heater, and the controller determines that the water level sensor signal in the clean water tank indicates that the clean water tank is not full.

[0034] Drainage completion conditions: The controller determines that the water heater is empty when the empty liquid level sensor signal is received, or the water pump has been running continuously for more than the maximum set time T2.

[0035] The above-described technical solution of the present invention achieves the following beneficial effects: This invention provides an airborne intelligent drinking water system for kitchens and its control method. The controller collects signals from the full-level, empty-level, and clear-water-tank level sensors of the electric water heater. When the controller detects that the system meets the automatic water filling conditions, it controls the water supply / drainage components to automatically replenish the electric water heater to full. When the controller detects that the system meets the automatic drainage conditions, it controls the water supply / drainage components to automatically drain the water from the electric water heater to the clear-water tank.
