As shown in FIG. 2 and FIG. 7, a water level control device for a micro-mist sauna device includes: a humidifying portion 16, a water storage tank 30, a water supply pipe and a valve 13 thereof, a drain pipe and a valve thereof 14, a DC power source 10, and a micro The processor 11 and the motor 12 are connected to the motor 12, and the water supply pipe and the valve 13 and the drain pipe and the valve 14 thereof are connected to the water storage tank 30, and the motor 12 is The DC power source 10 provides power, and the circuit also has a current monitoring device 15 that monitors the motor current value in real time; the microprocessor 11 controls the operation (start, stop, and speed adjustment) of the motor 12, and the opening of the water supply pipe valve 13 and Close, and open and close the drain valve 14. In this embodiment, the DC power source 10 can also be a 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 current magnitude, and the motor 12 drives the humidification unit. An actuator that rotates at a rapid speed to form fine water droplets.

Figure 7 is a schematic view showing the structure of the humidifying portion of the present invention; Figure 8 is a schematic view showing the connection between the humidifying portion and the motor of the present invention; and Figure 9 is a schematic view showing the structure of the micro-mist sauna device of the present invention. As shown 7-FIG. 9, the humidifying portion 16 has a slightly hollow conical shape that is enlarged upward, and the upper portion is connected to the motor 12, and the bottom portion is disposed on the side of the water storage tank 30. When the water level rises, the load increases and the current also increases. . The humidifying portion 16 is integrally provided with a shaft fixing portion 17 connected to the motor 12 from the bottom, and the shaft fixing portion 17 is a cylindrical structure in which the inner circle 23 of the ring of the annular bottom surface is extended to the opening portion 22 of the upper portion of the substantially hollow conical shape. The inside of the cylinder is connected to the motor 12 by a nut (not shown) or the like, so that the humidifying portion 16 is connected to the motor 12 through the shaft fixing portion 17 of the humidifying portion 16 at a position close to the motor 12. The humidifying portion 16 and the motor 12 are configured to suppress vibration due to assembly errors. Further, as the water suction port of the humidifying portion 16, the bottom surface thereof has a ring shape having a certain width and a plurality of holes 18, and the water passes through the plurality of holes 18 to rise to a hollow conical shape by the rotation of the humidifying portion 16. The inner surface of the portion 16.

Further, since the vibration amplitude of the humidifying portion 16 increases as the axial length of the motor 12 increases, by setting the shaft fixing portion 17 to the upper portion of the humidifying portion 22, the vibration when the motor 12 rotates is hardly transmitted to the humidifying portion 16 Further, the error caused by the combination between the humidifying portion 16 and the motor 12 is suppressed, and the rotation balance can be easily obtained. Thus, for the same water level, a stable current value of the motor 12 can be obtained, and the error in mass production can be suppressed.

The microprocessor 11 of the present invention can monitor the current and the rotational speed of the motor 12 very conveniently in real time. When there is no water in the water storage tank, the motor 12 drives the humidifying portion to rotate in the air, and the load is relatively small, as shown in FIG. When water is added to the water storage tank, the motor 12 drives the humidifying portion to rotate in the water, and the load is increased, that is, when the water level in the water storage tank rises, the load is correspondingly increased, since the voltage is kept constant, the motor 12 is The rotation speed is constant, so the current will increase as the water level rises. When the microprocessor 11 detects that the current rises to the specified range, the microprocessor 11 controls the water supply valve to close and stops the water supply; otherwise, when the water is in the water storage tank When the water forms fine water droplets and evaporates, the water level drops, and the current decreases as the water level decreases. When the microprocessor 11 detects that the current drops to the specified range, the microprocessor 11 controls the water supply pipe valve to open to start the water supply.

Therefore, as described above, in the case of a large amount of water, the current flowing through the motor 12 must be made large, and in the case of no water, the current flowing through the motor 12 must be minimized. Therefore, the present invention determines the level 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, it is determined in advance that the current flowing through the motor 12 in the state of insufficient water (or near water) in the water storage tank is Iinax, and the current value flowing through the motor 12 in the state of full water in the water storage tank is Iinax, and the above values are stored. Into the microprocessor to calibrate the state of the water level in the reservoir, and then through the real-time monitoring of the flow The current value of the motor 12 is compared with the above Imin and Imax, and the water level in the water storage tank can be judged. When the current current value 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, and the two preset data are used as indicators to determine whether water injection is required.

When the current current value monitored in real time is higher than the preset maximum current value Ix, the operation of the entire micro-mist sauna device is stopped, including stopping the motor, shutting off the water supply, and opening the drain valve. For safety reasons, when the preset current value reaches the full water current value Imax, the water level is not completely filled with the water storage tank, leaving a certain safety margin. 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 will 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 operation of the entire micro-mist sauna device must be stopped, and an audible alarm or other means of alarm can be issued according to the preset.

For more careful consideration, the present invention can also set the full water current value Imax to the condition that triggers the operation of the entire micro-mist sauna apparatus. It is also possible to select a stop running current value I s between the full water current value Imax and the highest current value Ix as a condition for triggering the operation of stopping the entire micro-mist sauna device, that is, the stop running current value Is is greater than or equal to the current value. Imax is less than or equal to the highest current value Ix.

The present invention also provides another control method in which the current value flowing through the motor 12 in the full water state is not set in advance, but the fixed current increase value A im is set to Ic in advance, and the current value flowing through the motor 12 is initially set. When the current increase value Δ Ιηι reaches Ic during the water storage after the preset minimum value Imin is reached, it is regarded as the full water state.

Figure 3 is a general flow chart 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 turned on, it is first determined whether there is water in the water storage tank and whether the existing water is sufficient to keep the micro-fog sauna device working for a period of time.

In this embodiment, the current value of the micro-mist sauna device for a period of time is kept to be the minimum value Imin, and when the monitored current current is less than the preset minimum value Imin, the automatic water supply control program is sequentially entered, that is, the micro-processing The water supply pipe valve 13 is opened, and the drain valve 14 is closed. Until the current current increase value A im reaches the preset value Ic, the microprocessor 11 controls the water supply pipe valve 13 to be closed. 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 be closed, the memory The current current value Imf is considered to be in a full water state, and the repeated cycle is performed as follows: When the Td period is passed and the current current value falls by a predetermined Id, and the water supply pipe valve 13 is controlled to open, when the current current value is restored When the current value Imf is reached, the water supply pipe valve 13 is controlled to be closed.

When the current current detected is greater than or equal to the preset minimum value Imin, the microprocessor controls the motor to keep running, and the control water supply valve and the drain valve are closed, and the current current value and the minimum value Imin are continuously monitored and compared in real time. Size relationship.

Fig. 4 is a flow chart showing 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 is started in this embodiment (step B1 '), the microprocessor 11 issues an instruction to control the opening of the water supply pipe valve 13, while the drive motor 12 starts to operate, and the rotational speed is fed back to the microprocessor. 11. When the microprocessor 11 determines that the motor 12 has been operated at a fixed speed of the Tb period, memorizes the current current Ime (initial value), and controls the drain valve 14 to close, continuing the water supply, before performing full water monitoring, The microprocessor 11 will also perform an abnormality in drainage and water supply. At this time, the displacement is larger than the water supply amount, and when the water supply pipe valve 13 and the drain pipe valve 14 are simultaneously opened, the water storage tank 30 does not store water, that is, the humidification portion 16 has not come into contact with the accumulated water.

The above operation can also be performed in the following step B1: After the automatic water supply control program is started, the microprocessor 11 issues an instruction to control the opening of the water supply pipe valve 13, while the drive motor 12 starts to operate for a period of time Ta, and the microprocessor 11 memorizes the current time. Current value Ime (initial value). Since the motor has the self-characteristic of the state of operating at a fixed speed after running for a period of time from the standstill, the length of the Ta period in the present embodiment is set in advance according to the actual working condition of the motor 1, After the motor 12 has been running for a period of time Ta from a standstill, the motor 12 should be in an ideal state for a smooth execution of a certain fixed speed command from the microprocessor 11 under a predetermined normal condition.

After the water supply pipe valve 13 in the above step B1 or step B1' is opened, the drain valve 14 is not closed, so that the water storage tank can be flushed to clean the water storage tank to keep it clean. The reason why the motor 12 is controlled to operate at a fixed speed is to memorize the current current value Ime, in order to inject the water to the drain valve 14 and the water supply valve during the subsequent injection of water into the water tank within the preset water volume range. 13 Whether the normal switch is monitored to prepare for the official operation of the micro-fog sauna device (spraying of fine water droplets). Step B2 (Drainage Abnormality Determination Program): If Ime is greater than the preset Im g at this time, the microprocessor 11 determines that the previously issued command to close the drain pipe valve 14 is not correctly executed, that is, the drainage is abnormal, the water supply valve 13 is turned off, and the motor 12 is stopped.

As shown in Fig. 11, after the above operation, the drain pipe door 14 is opened to enter the automatic water supply control program, and then step B (drain abnormality determination program) is performed. If Ime is repeated more than once in the preset Im g, or several times (for example, 3 times), the final decision is made.

The steps before the above final determination are specifically:

After step B2, return to the operation when the user issues the micro-mist sauna device to start the humidification operation command, BP: performs 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 after closing the water supply pipe valve 13;

The microprocessor 11 controls the motor 12 to start operation. After the Ta period, the microprocessor 11 memorizes the current current value Ime, or

The microprocessor 11 controls the motor 12 to start running, and the motor 12 speed is fed back to the microprocessor 11. When the microprocessor 11 determines that the motor 12 is operating at a fixed speed for a period of time Tb, the microprocessor 11 memorizes the current current value described above. Ime, then open the water supply valve 13, 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 Im g, perform step F,

Step F: Repeat step E. If the current value Ime is still detected to be greater than the preset Im g, the microprocessor 11 determines that the drainage is abnormal, stops the motor 12 from running, and stops the operation of the entire micro-mist sauna device.

When the microprocessor 11 determines that there is no abnormality in the drainage, whether or not the full water detection determination is made, with the already stored current value Ime as an initial value, when the motor 12 current increase value Δ Im reaches the preset value Ic (A lm-Ic ), The microprocessor 11 determines that the water storage tank is in a full water state, and memorizes the motor 12 current value Imf when the water is full, controls the water supply pipe valve 13 to be closed, and starts to enter the water level quantitative control program.

In the above full water detection judgment program, step B3 (water supply abnormality determination program) is also performed at the same time: After the drain valve 14 is closed for a period of Tc, for example, after 30 seconds, the current motor 12 current value is already memorized. The increase in the current value Ime has not yet reached the preset value. At Ic, the microprocessor 11 determines that the water supply is abnormal, the water supply valve 13 is closed, and the motor 12 is stopped.

This automatic water supply control program prevents the water in the water storage tank from overflowing and overflows the water storage tank. Moreover, it can prevent the water in the water storage tank from being too small and affecting the sauna effect. This automatic water supply control program can also prevent water pipes from being insufficient due to water pressure. The occurrence of insufficient water supply due to clogging or the like. At the same time, the characteristics of the motor current in the full water state are recorded, which serves as a basis for judging the need for water supply in the future.

In order to detect whether the previous drainage of the water storage tank 30 is accurately performed, that is, in order to accurately preset the value of Img, it is preferable that the detection position of Img is located where the diameter of the humidifying portion 16 is significantly changed. For example, the humidifying unit 16 is formed by joining the first cylinder 19 and the second cylinder 20 having different diameters, and the enlarged portion 21 is provided as a sharply enlarged portion. The current value of the motor 12 greatly changes at the enlarged portion 21, so that it can be easily Img was detected.

Further, regarding the detection position of Img, a rib or the like may be provided on the outer circumference of the humidifying portion 16 to rapidly change the rotational resistance, that is, a configuration in which the current of the motor 12 is increased.

Figure 12 is a graph showing the relationship between the water level and the current value of the present invention. It can be confirmed from the graph of Fig. 12 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 portion 21 is a sharply enlarged place, and the current value of the motor 12 largely changes during the process of the water level from the beginning of the enlargement portion 21 to the complete coverage of the enlarged portion 21. Therefore, it is appropriate to select any current value in the process from the beginning of the entry into the enlarged portion 21 to the complete coverage of the enlarged portion 21 as the detection of the presence or absence of a drainage abnormality. Of course, the invention does not limit the selected water level described above, and it is also feasible to select the water level at other locations as desired. However, the position of Img is lower than the water level of the overflow surface. Any of the current values in the process described above means that a current value can be selected and fixed at a preset time.

Fig. 5A is a flow chart of a water level quantitative control program of a water level control method of the present invention. After the automatic water supply control program ends, the embodiment enters the water level quantitative control program, specifically: when the microprocessor 11 monitors the full water, the above motor current value Imf is memorized, and it is considered to be in a full water state as a follow-up Thirst water is used for judging; the current of the motor is monitored in real time, the water supply is judged, and the already stored Imf is used as the initial value. When the motor current Δ Ιιη reduction amount reaches the Id value (A Im = Id), it is determined that the water supply is required. At the same time, the timing determination is made, whether the memory is passed as the initial value, whether or not the Td period has elapsed, such as 5 minutes, and if so, the water supply pipe is controlled. When the valve 13 is opened, the water supply starts; when the current value returns to the current value Imf after the water supply for a period of time, that is, the water is full, the water supply pipe valve 13 is closed, the water supply is stopped, and after that, the next water level quantitative control program water supply determination is made. The loop is repeated until the user actively powers off and stops using it.

This step monitors the change in the current value of the motor to determine when the water supply is needed, whether water is needed, etc., to ensure that the water level in the water reservoir remains within the preset range, thus ultimately ensuring the effectiveness of the micro-mist sauna.

As shown in FIG. 5B, the present invention also discloses another water level quantitative control program, specifically, when the microprocessor 11 detects full water, and starts to jump from the water supply control program to the water level quantitative control program, the monitoring When the current of the motor 12 reaches the minimum value Imin, the water supply pipe valve 13 is opened. When it is detected that the current of the motor 12 reaches the full water current value Imax, the water supply pipe valve 13 is controlled to be closed, the water supply is stopped, and thereafter, the cycle of the next water supply determination is continued, and the cycle is repeated. In this embodiment, when jumping from the water supply control program to the preset water level quantitative control program, it is also ensured that the water level is kept constant within a predetermined range to ensure the effect of the micro-mist sauna. As in the previous embodiment, when the current current value monitored in real time is higher than the preset maximum current value ,, the operation of the entire micro-mist sauna device is stopped (including the motor is stopped, the water supply is cut off, and the drain valve can be further opened).

Figure 6 is a graph showing the relationship between time and current values of the water level control of the present invention. As shown in the figure, due to the use of the DC power supply, when the water supply pipe valve 13 is closed, as the amount of water becomes smaller, the current of the motor 12 gradually becomes smaller; when the water supply pipe valve 13 is opened, the amount of water becomes large in a short time. The current of the motor 12 is rapidly increased.

Fig. 10 is a view showing the entire flow of the present invention from the start of operation to the stop operation, and the contents of Figs. 3 to 5 are simplified.

After the user issues a micro-mist sauna device to start the humidification command, the water supply pipe valve 13 and the water discharge pipe valve 14 are opened to provide water while draining. 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 water accumulated in the water storage tank 30 are discharged through the drain pipe valve 14.

After a predetermined period of time Te has caused the retained water accumulated in the water supply pipe valve 13 to be discharged, the water supply pipe valve 13 is closed, and after a predetermined time Tf, the automatic water supply control process is entered. Preface. Retained water refers to water located in the upstream side of the water supplied to the device, which is injected into the branch pipe. The so-called branch pipe refers to a pipe branched from the main waterway main pipe in order to supply water to the device.

Next, an explanation will be given of the operation of the user after the micro-mist sauna device stops the humidification operation command. After a period of time after the end of the operation, for example, after 10 minutes, the drain valve 14 is opened for a period of time Tg to discharge the water of the water storage tank 30. At this time, the humidifying portion 16 starts to rotate again, and the water droplets adhering to the inner surface and the outer surface are continuously sprayed to the surroundings. Then, the water supply pipe valve 13 is temporarily opened for a short period of time Th, for example, for 10 seconds, and water is supplied to clean the scale component accumulated in the water storage tank 30 and discharged. After sufficient time has elapsed to allow the water remaining in the water storage tank 30 to be discharged, the drainage operation is completed. After the draining, the automatic drying control program is started, and the warm air is blown through the water storage tank 30, and the humidifying unit 16 is continuously driven to dry the humidifying unit 16 and the water storage tank 30. After sufficient time has elapsed to dry the water storage tank 30 and the humidifying portion 16, the heating air blowing means 33 and the humidifying portion 16 are stopped, and the drain valve 14 is closed to end the drying operation. This will stop in the absence of water droplets in the device. Further, by the rotation of the humidifying portion 16, the water droplets adhering to the surface and the inner surface of the humidifying portion 16 are removed, and the weight increase or the load bearing due to the scale adhered to the humidifying portion 16 itself can be suppressed, and a stable current value of the motor 12 can be obtained.
