Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea bar machines, and in particular to a high-flow instant hot tea bar machine drive control system. Background Technology
[0002] A tea bar machine can be considered an upgraded version of a water dispenser. It combines the functions of a water dispenser and a tea stove, yet differs from traditional water dispensers. Existing wooden tea bar machines have limited functionality. Customer feedback indicates that they only provide basic cooling and heating for drinking water, lacking refrigeration and preservation capabilities. For example, cold drinks and ice cream, which require refrigeration during gatherings, cannot be kept fresh. Therefore, in response to customer demand, our company designed a tea bar machine with a built-in refrigerator. During the integration of the refrigeration function, we discovered that adding a pre-made refrigerator directly into the tea bar machine would be inconvenient because it requires separate power and control, and cannot be centrally controlled via the tea bar machine's control panel. Therefore, our company conducted research and development to integrate a refrigerator with cooling and insulation functions into a customized tea bar machine. Through the design of the tea bar machine's circuit structure, we achieved unified drive and control.
[0003] During the research and development process, it was discovered that drinking water requires a refrigeration compressor during the cooling process, and the refrigeration of a refrigerator also requires a refrigeration compressor. If it could be controlled by a single refrigeration compressor, it would greatly save cabinet space and cost, while the refrigeration compressor of a finished refrigerator cannot be disassembled separately.

[0017] The present invention will be further described below.
[0018] Example: A drive control system for a high-flow-rate instant hot tea bar machine, see [link / reference] Figure 1 The system includes a main control circuit board 1 for the tea bar machine, an operation panel 2, a bottled water tank 3, a hot water outlet pipe 4, a cold water outlet pipe 5, and a water outlet 6. The inlets of the hot water outlet pipe 4 and the cold water outlet pipe 5 are located inside the bottled water tank 3, and the outlets of the hot water outlet pipe 4 and the cold water outlet pipe 5 are connected to the water outlet 6. The hot water outlet pipe 4 is equipped with a hot water pump 7, an inlet water temperature sensor 8, a flow meter 9, a power adjustable heating module 10, and an outlet water temperature sensor 11. The maximum power of the heating module 10 is 2200W. The hot water pump 7 is a variable frequency pump. The flow meter 9, the inlet water temperature sensor 8, and the outlet water temperature sensor 11 are respectively connected to the signal acquisition terminal of the main control circuit board 1 of the tea bar machine. The hot water pump 7 and the heating module 10 are respectively electrically connected to the main control circuit board 1 of the tea bar machine.
[0019] This invention relates to a device where the power of both the hot water pump 7 and the heating module 10 is adjustable and controllable. The device uses an inlet water temperature sensor 8 and an outlet water temperature sensor 11 to detect the water temperature at both ends of the heating module 10 and transmits the detected data to the main control circuit board 1 of the tea bar machine. A flow meter 9 detects the flow rate in the hot water outlet pipe 4 and feeds it back to the main control circuit board 1. The main control circuit board 1 then controls the power of both the heating module 10 and the hot water pump 7 based on the collected data. During instantaneous heating, the main control circuit board 1 first activates the hot water pump 7 at its maximum power to ensure maximum water supply. This increases the power of the heating module 10, thus achieving instantaneous hot water heating. If the heating module, even at its maximum power, cannot heat the outlet water to the set temperature, the power of the hot water pump 7 is reduced to decrease the water flow, ensuring the outlet temperature and thus guaranteeing the maximum instantaneous hot water output.
[0020] Normally, when the inlet water temperature is not too low, the above solution can fully achieve instantaneous high-flow-rate water output. However, for some areas with lower temperatures, the inlet water temperature is too low to heat to a higher temperature in one go. Based on the above circuit structure, this utility model adds the design of a preheating water tank 12, and its drive control circuit structure is as follows:
[0021] It also includes a preheating water tank 12 and a return water pipe 13. The preheating water tank 12 is connected to the hot water outlet pipe 4 and is located between the hot water supply pump 7 and the inlet water temperature sensor 8. A reheating water pump 14 is provided on the hot water outlet pipe 4 between the preheating water tank 12 and the heating module 10. A three-way solenoid valve is also provided on the hot water outlet pipe 4 at the outlet end of the heating module 10. The outlet of the three-way solenoid valve is divided into two paths, one of which is connected to the water outlet 6, and the other is connected to the preheating water tank 12 through the return water pipe 13.
[0022] The operation method for instant heating with the preheating water tank 12 circuit is as follows: Connect the power supply, press the power button on the operation panel 2 to open the operation panel 2, and then press the corresponding temperature button on the operation panel 2. The operation panel 2 has multiple temperature selection buttons. At this time, the water in the preheating water tank 12 is above the minimum water level, and the hot water pump starts to work, drawing the water from the preheating water tank 12 into the heating body. At the same time, the heating circuit starts to work to heat the water flowing into the heating body. At this time, the main control circuit board 1 of the tea bar machine will synchronously detect the inlet and outlet water temperatures, and adjust the water output and heating power according to the detection to ensure that the outlet temperature and water output reach the set values.
[0023] When the inlet water temperature is too low to be heated to the set temperature in one go, the water temperature can be heated to 50°C through the preheating water tank 12, and then the water can be sent to the 2200W heating module 10 for heating through the reheating water pump 14. The water output is increased by 30% compared with the conventional method, which solves the problem of low water output of traditional instant water heaters.
[0024] The operation method for preheating and heating water is as follows: Connect the power supply and press the power button on the operation panel 2 to open the operation panel 2. At this time, the machine automatically detects the water level of the preheating water tank 12. When there is no water in the preheating water tank 12, the hot water supply pump 7 of the preheating water tank 12 starts to work until the water level of the preheating water tank 12 reaches the maximum water level and then stops pumping water. When the water level of the preheating water tank 12 drops to the minimum water level, the hot water supply pump 7 restarts to pump water. When the circuit detects that the water level of the preheating water tank 12 is above the minimum water level, the heating module 10 starts, and the hot water pump 14 works to send the water in the preheating water tank 12 into the heating module 10 for heating. After heating, because the three-way solenoid valve 15 is not working and the outlet is closed, the water will flow back to the return water pipe 13 to circulate and heat the preheating water tank 12. After the water temperature of the preheating water tank 12 reaches the set value, heating stops, and the three-way solenoid valve 15 opens to discharge water.
[0025] The preheating tank 12 is equipped with a water level detector 19, which is connected to the signal acquisition terminal of the main control circuit board 1 of the tea bar machine, and can detect the water level in the preheating tank 12 in real time.
[0026] The preheating water tank 12 is equipped with a UV sterilization lamp 16, which is electrically connected to the main control circuit board 1 of the tea bar machine. The water in the preheating water tank 12 can be sterilized at regular intervals by using low-pressure ultraviolet sterilization lamps 16.
[0027] The top of the preheating water tank 12 is provided with an exhaust port 17 for external pressure relief, and the bottom of the preheating water tank 12 is provided with a drain port 18 for regular drainage and cleaning. The exhaust port 17 is provided with a one-way valve, and the drain port 18 is provided with a switch valve.
[0028] The cold water outlet pipe 5 is also equipped with a cold water supply pump 20 and a cooling tank 21 for cooling drinking water. The cooling tank 21 is equipped with a refrigeration circuit, which includes a refrigeration compressor 23, a condenser 24, a refrigerant refrigeration pipe 25, and a refrigerant return pipe 26. The cooling tank 21 contains an evaporator 22 for cooling. The refrigeration compressor 23 is connected to the condenser 24 and the evaporator 22 in the cooling tank 21 in sequence through the refrigerant refrigeration pipe 25. The evaporator 22 is connected to the refrigerant return port of the refrigeration compressor 23 through the refrigerant return pipe 26. The refrigeration compressor 23 and the condenser 24 are electrically connected to the main control circuit board 1 of the tea bar machine. When room temperature water is needed, the cold water supply pump 20 is started, and the refrigeration circuit is not started, so the tea bar machine can raise the room temperature water. When chilled water is needed, the cold water supply pump 20 is started at the same time, and the refrigeration circuit is started, which cools the water flowing through the cold water outlet pipe 5 through the cooling tank 21.
[0029] The refrigeration system operates as follows: Connect the power supply and press the power button on control panel 2 to open it. Then, press the refrigeration button on control panel 2. The refrigeration circuit will then activate, supplying 220V power to the refrigeration compressor 23 via the main control circuit board 1. The compressor 23 will then begin operation. Once the water temperature reaches the set value, the compressor 23 will stop working. When the water temperature rises to the set maximum temperature, the compressor 23 will restart and begin refrigeration. The standard temperature settings are: stop at 6℃, restart at 12℃. If the water temperature is below 12℃, the compressor 23 will not operate, and the refrigeration circuit will be in standby mode.
[0030] The cold chamber 21 is equipped with a low temperature sensor 27, which is connected to the signal acquisition terminal of the main control circuit board 1 of the tea bar machine. The low temperature sensor 27 can detect the temperature inside the cold chamber 21.
