As shown in Figures 2 and 7, a water level control device for a micro-mist sauna device includes: a humidification unit 16, a water storage tank 30, a water supply pipe and its valve 13, a drain pipe and its valve 14, a DC power supply 10, a micro Processor 11, motor 12, the humidifier 16 is connected to the motor 12, the water supply pipe and its valve 13 and the drain pipe and its valve 14 are connected to the water storage tank 30, and the motor 12 is controlled by the DC power supply 10 provides electric power, also has the current monitoring device 15 of real-time monitoring motor current value in the circuit; Described microprocessor 11 controls the operation (starting, stopping and speed adjustment) of motor 12, and the opening and closing of water supply pipe valve 13 Closing, and the opening and closing of drainpipe valve 14. In this embodiment, the DC power supply 10 can also be the power supply unit of the entire micro-mist sauna device, the microprocessor 11 is a processing unit that controls the operation of the motor 12 and the magnitude of the current, and the motor 12 is used to drive the humidifier. 16 The execution unit that rotates rapidly to form fine water droplets.

Fig. 7 is a schematic structural view of the humidifying part of the present invention; Fig. 8 is a schematic view of the connection between the humidifying part and the motor of the present invention; Fig. 9 is a schematic structural view of the micro-mist sauna device of the present invention. As shown in Figures 7-9, the humidifying part 16 is a slightly hollow conical shape that expands upward. get bigger. The humidifying part 16 is integrally provided with a shaft fixing part 17 connected to the motor 12 from the bottom, and the shaft fixing part 17 is a cylinder structure in which the inner circle 23 of the ring of its annular bottom surface extends to the upper opening part 22 of a slightly hollow conical shape, The inside of the cylinder is connected to the motor 12 through nuts (not shown in the figure), etc., so the humidifying part 16 is connected to the motor 12 through the shaft fixing part 17 integrated with the humidifying part 16 at a position close to the motor 12 to humidify The part 16 and the motor 12 have a structure that can suppress vibration due to assembly errors. In addition, as the water suction port of the humidifying part 16, the bottom surface is a circular shape with a certain width provided with a plurality of holes 18, and by the rotation of the humidifying part 16, water passes through the plurality of holes 18 and rises to the hollow conical humidification area. The inner surface of part 16.

And because the vibration amplitude of the humidifying part 16 can increase along with the increase of the axis length of the motor 12, the vibration when the motor 12 rotates is difficult to be transmitted to the humidifying part 16 by arranging the shaft fixing part 17 integrally on the top of the humidifying part 22, Furthermore, an error due to the combination of the humidifying unit 16 and the motor 12 is suppressed, and the rotation balance can be easily obtained. In this way, for the same water level, a stable current value of the motor 12 can be obtained, and errors during mass production can be suppressed.

The microprocessor 11 of the present invention can monitor the current and the rotating speed of the motor 12 very conveniently and in real time. When there is no water in the water storage tank, the motor 12 drives the humidifying part to rotate in the air, and the load is relatively small, as shown in FIG. 6 , when After water is added to the water storage tank, the motor 12 drives the humidifier to rotate in the water, and the load increases. That is to say, when the water level in the water storage tank rises, the load increases accordingly. Since the voltage is kept constant, the speed of the motor 12 No change, so the current will increase with the rise of the water level. When the microprocessor 11 detects that the current rises to the specified range, the microprocessor 11 controls the valve of the water supply pipe to close and stop the water supply; otherwise, when the water in the water tank When fine water droplets are formed and evaporated, the water level drops, and the current drops with the decrease of the water level. When the microprocessor 11 detects that the current drops to a specified range, the microprocessor 11 controls the valve of the water supply pipe to open to start water supply.

Therefore, as mentioned above, when there is a lot of water, the current flowing through the motor 12 must become larger, and when there is no water, the current flowing through the motor 12 must be the smallest. Therefore, the present invention judges the height of the water level in the water storage tank and the amount of water by measuring the current value flowing through the motor 12 . Therefore determine in advance that the current value of the motor 12 flowing through the motor 12 under the water shortage (or near anhydrous) state in the water storage tank is Imin, the current value of the motor 12 flowing through the motor 12 under the full water state in the water storage tank is Imax, and the above-mentioned numerical value Store in the microprocessor to calibrate the state of the water level in the water storage tank, and then compare the above-mentioned Imin and Imax by monitoring the current value flowing through the motor 12 in real time to judge the water level in the water storage tank. When the current current value When it rises to the preset full water current value Imax, it is regarded as a full water state. When the current current value drops to the preset minimum value Imin, it is regarded as a thirsty water state. The two preset data are used as Indicators to determine if water injection is required.

When the current value of the real-time monitoring is higher than the preset maximum current value Ix, stop the work of the entire micro-mist sauna device, including motor stop, cut off the water supply, and further open the drain pipe valve. For safety considerations, when the preset current value reaches the full water current value Imax, the water level does not completely fill the water storage tank, leaving a certain safety margin. And when the preset current value reaches the highest current value Ix, it means that the water level has completely filled the water storage tank and is about to overflow. Therefore, the highest current value Ix is slightly larger than the full water current value Imax. Therefore, if the current current value is higher than the preset maximum current value Ix, it is judged that the water is about to overflow, so the work of the entire micro-mist sauna device must be stopped, and an audible alarm or other alarms can be issued according to the preset settings.

For more prudent considerations, the present invention may also set the full water current value Imax as a condition to trigger stopping the work of the entire micro-mist sauna device. It is also possible to select a stop current value Is between the full water current value Imax and the highest current value Ix as a trigger to stop the work of the entire micro-mist sauna device, that is, the stop current value Is is greater than or equal to the current value Imax , and less than or equal to the highest current value Ix.

The present invention also provides another control mode, which does not pre-set the current value flowing through the motor 12 under the state of full water in advance, but presets a fixed current increase value ΔIm as Ic, when the initial current value flowing through the motor 12 is low When the current increase value ΔIm reaches Ic during the water storage process after the preset minimum value Imin, it is regarded as a full water state.

Fig. 3 is a general flowchart of the water level control method of the present invention. As shown in the figure, after the water level control device of the micro-mist sauna device is powered on, it first determines whether there is water in the water storage tank, and whether the existing water is enough to keep the micro-mist sauna device working continuously for a period of time.

This embodiment presets in advance that the current value that can keep the micro-mist sauna device working continuously for a period of time is the minimum value Imin. When the current current monitored is less than the preset minimum value Imin, it will enter the automatic water supply control program in turn, that is, the micro-processing The controller controls the valve 13 of the water supply pipe to open, and controls the valve 14 of the drain pipe to close. When the current increase value ΔIm reaches the preset value Ic, the microprocessor 11 controls the valve 13 of the water supply pipe to close. This embodiment also enters the water level quantitative control program after the automatic water supply control program, that is, after the microprocessor controls the water supply pipe valve 13 to close, the current current value Imf is memorized. After the Td time period and the current current value drops to a predetermined Id, the water supply pipe valve 13 is controlled to open, and when the current current value returns to the current value Imf, the water supply pipe valve 13 is controlled to be closed.

When the monitored current is greater than or equal to the preset minimum value Imin, the microprocessor controls the motor to keep running, controls the water supply pipe valve and the drain pipe valve to close, and continues to monitor and compare the current current value with the minimum value Imin in real time. size relationship.

Fig. 4 is a flow chart of the automatic water supply control program of the water level control method of the present invention. As shown in the figure, after the automatic water supply control program starts in this embodiment (step B1'), the microprocessor 11 issues an instruction to control the opening of the valve 13 of the water supply pipe, and at the same time the drive motor 12 starts running, and the speed is fed back to the microprocessor 11. When the microprocessor 11 judges that the motor 12 has been running at a fixed speed for a period of time Tb, the current Ime (initial value) is memorized, and the valve 14 of the drain pipe is controlled to close, and the water supply is continued. Before the full water monitoring, The microprocessor 11 will also perform abnormal judgments on drainage and water supply. At this time, the displacement is more than the water supply. When the water supply valve 13 and the drain valve 14 are opened simultaneously, the water storage tank 30 will not store water, that is, the humidifying part 16 has not yet touched the accumulated water.

The above actions can also be carried out in the following steps B1: after the automatic water supply control program starts, the microprocessor 11 sends an instruction to control the opening of the water supply pipe valve 13, and the drive motor 12 starts to run for a period of time Ta, and the microprocessor 11 memorizes the current current Value Ime (initial value). Since the motor has its own characteristic that it can enter the state of running at a fixed speed after running for a period of time from a standstill, the length of the Ta time period in this embodiment is set in advance according to the working conditions of the actual motor 12. After the motor 12 starts to run for a period of time Ta from a standstill, under preset normal conditions, the motor 12 should reach the ideal state of smoothly executing the instructions sent by the microprocessor 11 with a certain fixed speed.

After the water supply pipe valve 13 in the above-mentioned steps B1 or step B1' is opened, the drain pipe valve 14 is not closed, so the water storage tank can be flushed to clean the water storage tank to keep it clean. The reason why it is necessary to control the motor 12 to run at a fixed speed before memorizing the current current value Ime is to ensure that the valve 14 of the drain pipe and the valve of the supply pipe Whether 13 is all normal switch is monitored, thus prepares for the formal operation (ejection of tiny water droplets) of the micro-mist sauna device.

Step B2 (drainage abnormal judging program): if Ime is greater than the preset Img at this time, then the microprocessor 11 determines that the instruction for closing the drain pipe valve 14 sent before has not been correctly executed, that is, the drainage is abnormal, and the water supply pipe valve 13 Close, stop motor 12 running.

As shown in Figure 11, after the above actions, open the drainpipe valve 14 to enter the automatic water supply control program, and then proceed to step B (drainage abnormality determination program). If the situation that Ime is greater than the preset Img is repeated once, or several times (for example, 3 times), a final determination is made.

The above-mentioned steps before the final judgment are specifically:

After step B2, return to the operation when the user sends the micro-mist sauna device to start the humidification operation command, that is: carry out the following steps E and F:

Step E: the microprocessor 11 controls the water supply pipe valve 13 and the drain pipe valve 14 to open for a period of time Ti and then close the water supply pipe valve 13;

After the microprocessor 11 controls the motor 12 to start running for a period of Ta, the microprocessor 11 memorizes the above-mentioned current current value Ime, or

The microprocessor 11 controls the motor 12 to start running, and the speed of the motor 12 is fed back to the microprocessor 11. When the microprocessor 11 determines that the motor 12 runs at a fixed speed for a period of time Tb, the microprocessor 11 memorizes the above-mentioned current current value Ime, then open the water supply valve 13 and close the drain valve 14:

Comparing the current value Ime with the preset Img, if the current current value Ime is greater than the preset Img, go to step F,

Step F: Repeat step E several times, if the current value Ime is still detected to be greater than the preset Im g, the microprocessor 11 judges that the drainage is abnormal, stops the motor 12, and stops the work of the entire micro-mist sauna device.

After the microprocessor 11 judges that there is no abnormality in the drainage, it will detect and judge whether it is full of water. With the current value Ime memorized as the initial value, when the motor 12 current increase value ΔIm reaches the preset value Ic (ΔIm=Ic), the microprocessor Device 11 determines that the water storage tank is full of water, and remembers the current value Imf of motor 12 when it is full of water, controls the water supply pipe valve 13 to close, and begins to enter the water level quantitative control program.

In the above full water detection and judgment procedure, step B3 (water supply abnormality judgment procedure) is also carried out simultaneously: after the drainpipe valve 14 is closed for a period of time Tc, such as after 30 seconds, the current value of the current motor 12 is changed from the stored current When the initial rise of the value Ime does not reach the preset Ic, the microprocessor 11 determines that the control water supply is abnormal, the valve 13 of the water supply pipe is closed, and the motor 12 is stopped.

This automatic water supply control program can prevent the water in the water storage tank from being too full and overflowing the water storage tank, and it can also prevent the sauna effect from being affected by too little water in the water storage tank. Insufficient water supply caused by blockage and other reasons. At the same time, record the characteristics of the motor current when it is full of water, as a basis for judging when water supply is required in the future.

In order to detect whether the previous drainage of the water storage tank 30 is performed accurately, that is, to accurately preset the value of Img, it is best to make the detection position of Img located at a place where the diameter of the humidifying part 16 changes significantly. For example, the humidifying part 16 is formed by joining the first tube 19 and the second tube 20 with different diameters, and the enlarged part 21 is set as a place for sharp expansion, and the current value of the motor 12 at the enlarged part 21 will change greatly, so it can be easily Img was detected accurately.

In addition, regarding the detection position of Img, ribs or the like may be provided on the outer periphery of the humidifying unit 16 so that the rotation resistance changes rapidly, that is, a structure that increases the current of the motor 12 may be used.

Fig. 12 is a schematic diagram of the relationship between the water level and the current value in the present invention. From the graph of FIG. 12 , it can be confirmed that when the water level reaches the enlarged portion 21 of the humidifying portion 16 , the current value changes significantly. This is because the enlarged part 21 is a place that expands rapidly, and the current value of the motor 12 will change greatly during the process from when the water level just enters the enlarged part 21 to completely covers the enlarged part 21. Therefore, it is more appropriate to select any current value of Img during the process from when the water level just enters the enlarged portion 21 to when it completely covers the enlarged portion 21 to detect whether there is abnormal discharge. Of course, the present invention is not limited to the above-mentioned selected water level, and it is also feasible to select the water level at other positions according to requirements. However, the position of Img is lower than the water level of the overflow surface. Any current value in the process mentioned above means that one of the current values can be selected and fixed during preset.

Fig. 5A is a flow chart of a water level quantitative control program in a water level control method of the present invention. After the automatic water supply control program ends, the present embodiment enters the water level quantitative control program, which specifically refers to: when the microprocessor 11 detects that the water is full, the above-mentioned motor current value Imf is memorized. It is used for judging thirsty water; it monitors the current of the motor in real time and executes the judgment of water supply. The stored Imf is used as the initial value. Carry out timing judgment at the same time, start from remembering Imf as initial value and whether through Td time period, as 5 minutes, if yes, then control water supply pipe valve 13 to open, water supply starts; , that is full of water, the control water supply pipe valve 13 is closed, and the water supply is stopped. After that, enter the cycle of water supply determination of the next water level quantitative control program, and repeat until the user actively cuts off the power to stop using.

In this step, by monitoring the change of the current value of the motor, it is determined when and whether water needs to be supplied, etc., so as to ensure that the water level in the water storage tank remains within the preset range, thereby finally ensuring the effect of the micro-mist sauna.

As shown in Figure 5B, the present invention also discloses another water level quantitative control program, which specifically refers to: when the microprocessor 11 detects that it is full of water, it jumps from the water supply control program to the water level quantitative control program. When the electric current of motor 12 reaches minimum value Imin, water supply pipe valve 13 is opened. After the electric current of monitoring motor 12 reaches full water current value Imax, control water supply pipe valve 13 to close, stop water supply, after this, enter the circulation of next water supply judgment, repeat ceaselessly. In this embodiment, when the water supply control program jumps to the preset water level quantitative control program, it can also ensure that the water level remains constant within a predetermined range, so as to ensure the effect of the micro-mist sauna. Same as the previous embodiment, when the current value of the real-time monitoring is higher than the preset maximum current value Ix, stop the work of the whole micro-mist sauna device (including the motor stops running, the water supply is cut off, and the drain pipe valve can be opened further).

Fig. 6 is a relationship diagram between time and current value of water level control in the present invention. As shown in the figure, due to the use of DC power supply, when the water supply pipe valve 13 is closed, the current of the motor 12 gradually decreases as the water volume decreases; when the water supply pipe valve 13 is opened, the water volume increases in a short time. The current of the motor 12 increases rapidly.

Fig. 10 is a schematic diagram showing the overall process from start to stop of the present invention and simplifying the contents of Fig. 3 to Fig. 5 .

After the user issues a humidification instruction to the micro-mist sauna device, the water supply pipe valve 13 and the drain pipe valve 14 are opened to supply water and drain water at the same time. At this time, the stagnant water on the upstream side of the water supply pipe valve 13 is discharged, and the scale and dew condensation accumulated in the water storage tank 30 are discharged through the drain pipe valve 14 .

After a predetermined period of time Te makes the stagnant water accumulating in the upper stream of the water supply pipe valve 13 be discharged, the water supply pipe valve 13 is closed, and then enters the automatic water supply control program after a period of predetermined time Tf. The stagnant water refers to the water that is located on the upstream side of the water supplied to the device and injected into the branch pipe. The so-called branch pipe refers to the pipe that branches off from the main water channel to supply water to the device.

The following is a description of the action after the user issues a command to stop the humidifying operation of the micro-mist sauna device. After a period of time after the end of operation, for example, after 10 minutes, open the drain pipe valve 14 for a period of time Tg to discharge the water in the water storage tank 30 . At this time, the humidifier 16 starts to rotate again, and the water droplets adhering to the inner surface and the outer surface continue to spray around. Then the water supply pipe valve 13 is temporarily opened for a short period of time Th, such as 10 seconds, to provide water to clean the scale components accumulated in the water storage tank 30 and then discharge it. After sufficient time has elapsed to drain the water stagnant in the water storage tank 30, the draining operation ends. After draining, the automatic drying control program starts, and the warm air flows through the water storage tank 30 through the heating air supply means 33, and the humidifying part 16 is continuously driven to dry the humidifying part 16 and the water storage tank 30. After enough time is made to dry around the water storage tank 30 and the humidifying part 16, the heating air supply means 33 and the humidifying part 16 stop running, and the drain pipe valve 14 is closed to end the drying operation. This will stop with no water droplets present in the device. And through the rotation of the humidifying part 16, the water droplets adhering to the surface and inner surface of the humidifying part 16 are removed, and the weight increase or partial load-bearing caused by the scale attached to the humidifying part 16 itself can be suppressed, thereby obtaining a stable current value of the motor 12.
