4 and 5 are different examples showing the amount of change in load according to the present invention.

Hereinafter, a method for controlling an acupressure unit for a thermal therapy device according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, the acupressure control method for a thermal therapy device according to the present invention

(a) step (S100) of measuring the load applied to the acupressure unit (13) by the user by the weight sensing unit (20), and (a) calculating the amount of change in load based on the measured load value (S100) (b) step (S200) and (c) step (S300) of adjusting the lifting and lowering change amount or driving speed of the acupressure unit 13 according to the load change amount.

First, as shown in FIGS. 1 and 2, step (a) (S100) according to the present invention

This is a process of detecting the load of the user loaded on the weight sensing unit 20 located below the acupressure unit 13 and measuring the load value.

To this end, one end of the pivoting member 11 is hinged to the body (not shown), and the pivoting member 11 is provided with an acupressure module 10 having an acupressure unit 13 disposed thereon.

In addition, a weight sensing unit 20, that is, a load cell, is mounted on one upper side of the pivoting member 11 or the lower side of the acupressure unit 13 of the acupressure module.

In this case, when the weight sensing unit 20 is mounted on the upper portion of the swing member 11, the user's load is applied to the acupressure unit 13, and the lower surface of the acupressure unit 13 presses the weight sensing unit 20, At this time, the weight sensing unit 20 detects the load value by the applied pressure.

In addition, when the weight sensing unit 20 is mounted on the lower part of the acupressure unit 13, when the user's load is applied to the acupressure unit 13, the lower surface of the weight sensing unit 20 is in contact with the upper surface of the turning member 11 to pressurize At this time, the weight sensing unit 20 senses the load value by the applied pressure.

That is, regardless of whether the weight sensing unit 20 is mounted on either the turning member 11 or the acupressure unit 13, there is no significant difference in detecting and measuring the load value because it is disposed between the acupressure unit 13 and the pivoting member 11. .

Therefore, the moment the user's body contacts the acupressure unit 13, the user's load is applied to the acupressure unit 13, and the load or pressure applied at this time is transmitted to the weight sensing unit 20, so that the load value can be measured. .

Next, as shown in FIGS. 1 and 2, step (b) (S200) according to the present invention

This is a process of calculating the load change amount after comparing the load change amount, that is, the current load value (Sn) and the load value (Sn-1) of the previous step, based on the load value measured in step (a) (S100).

That is, although the acupressure module 10 is not shown in the accompanying drawings, a horizontal transfer means is provided so that during massage, the acupressure module 10 can be transported in a horizontal direction.

Therefore, when the acupressure module 10 is moved in the horizontal direction by the horizontal transfer means, the user's load is applied to the acupressure unit 13 in contact with the user's body. In this case, since the user's body is curved, the acupressure unit 13 ), the momentary load applied to the load changes.

At this time, the difference between the current load value (Sn) measured by the weight sensor 20 and the load value (Sn-1) detected in the previous step is calculated to obtain a load change amount.

That is, as shown in (a) of FIG. 3, if the current load value (Sn) is smaller than the load value (Sn-1) of the previous step, the load currently applied to the acupressure unit 13 is the acupressure unit 13 in the previous stage. ) is smaller than the load applied to the load, and the load is reduced.

Conversely, as shown in (b) of FIG. 3, when the current load value (Sn) is greater than the load value (Sn-1) of the previous step, the load currently applied to the acupressure unit 13 is applied to the acupressure unit in the previous step. This is the case when the load is increased when the load is greater than the load.

Therefore, while the acupressure module 10 moves in the horizontal direction by the horizontal transport means, the weight sensor 20 continuously detects and measures the load applied to the acupressure unit 13 according to the user's body curve,

By using the amount of change in the measured load values detected in this way, the amount of change in elevation of the acupressure unit 13 can be adjusted in real time.

As shown in Figures 1 and 2, step (c) (S300) according to the present invention

This is a process of controlling and adjusting the lifting and lowering change of the acupressure unit 13 or the driving speed, or both, by using the load change in step (S200) of (b).

To this end, although not shown in the accompanying drawings, the acupressure module 10 is provided with an elevating means capable of adjusting the height of the acupressure unit 13 by turning the pivoting member 11 in the vertical direction.

As shown in (a) of FIG. 3, when the load change amount by step (b) (S200), that is, the current load value (Sn) is greater than the load value (Sn-1) of the previous step ( When the load decreases), it is necessary to raise and lower the acupressure unit 13, and therefore, the lifting and lowering means rotates the pivoting member 11 of the acupressure module 10 upward so that the acupressure unit 13 moves up and down.

On the contrary, as shown in (b) of FIG. 3, when the current load value (Sn) is greater than the load value (Sn-1) of the previous step (when the load increases), it is necessary to lower the acupressure unit 13. And, therefore, the elevating means rotates the pivoting member 11 of the acupressure module 10 downward so that the acupressure unit 13 descends.

That is, by raising or lowering the acupressure unit 13 according to the change in load, the pressure by the acupressure unit 13 can be maintained constant.

In addition, when there is no load change, that is, when the current load value (Sn) and the previous load value (Sn-1) are the same, or when the load change is very small, the acupressure unit 13 neither rises nor descends. It can be set to a stopped state.

However, in this case, the amount of load change varies according to the body curvature, and in order to compensate for this deviation and maintain a constant acupressure force, there is a limit to maintaining the acupressure force uniformly only by the amount of change in the lifting and lowering of the acupressure unit according to the amount of load change.

Therefore, the difference between the current load value (Sn) and the previous load value (Sn-1) is used, and it is preferable to adjust the driving speed of the pressure unit as well as the amount of displacement of the pressure unit 13.

That is, when the deviation of the load variation is large, the lifting or lowering displacement of the acupressure unit 13 is determined in proportion to the load variation in the case of a large change in the user's body shape, and in addition, the vertical transfer speed (elevation and descent speed) of the acupressure unit and the horizontal It is necessary to adjust the transfer speed.

Therefore, by adjusting the lifting or lowering displacement and driving speed of the acupressure unit 13 according to the deviation of the change in load to suit the user's body shape, the acupressure force by the acupressure unit 13 can be maintained uniformly during massage work. .

Furthermore, the method for adjusting the height of the acupressure unit according to the present invention obtains scan information of the user's body using a change in load or a movement trajectory of the acupressure unit according to the load change, so that a massage operation suitable for the characteristics of the user's body can be performed.

This is because the acupressure part moves in the horizontal direction as described above and is in contact with the user's body to calculate the change in load, and according to the calculated load change amount, the change in the lifting and lowering of the acupressure part and the driving speed (vertical transfer speed and horizontal transfer speed) The controller collects and acquires the data about it.

The information collected in this way can be used as scan information for the same user, thereby maintaining a uniform acupressure force, thereby enabling a more efficient massage.

Therefore, it is possible to check the user's body characteristics, in particular, the curvature of the spine in advance by utilizing the scan information obtained as described above, and using this, apply the massage section or acupressure points according to the user's spine characteristics to suit the user's characteristics This enables user-customized massage operation.

Hereinafter, the behavior of the acupressure unit 13 according to the present invention will be described in more detail through two embodiments.

First, FIG. 4 is a graph for showing the behavior of the acupressure unit 13 in comparison with the reference pressure by converting the change in load according to the bending of the user's body into a pressure value according to the first embodiment.

In this case, when the change in the user's body curvature is relatively small (point A), that is, when the acupressure unit 13 moves a part such as the user's back, and on the contrary, when the change in the user's body curve is large (point B) , that is, the moment the acupressure unit 13 moves from the user's waist to the buttocks or the moment it moves from the hips to the thighs, etc.

Therefore, in order to specify the amount of change in elevation and descent of the acupressure unit 13 according to the amount of change in load, a reference pressure for the pressure applied by the acupressure unit 13 is set, and the reference pressure and the amount of change in load are converted into pressure values and compared After that, it is possible to determine the amount of change in the lifting and lowering of the acupressure unit 13 by the deviation.

That is, assuming that the reference pressure by the acupressure unit 13 is '10kg/cm ² 'as shown in FIG. 4, when the pressure value of the load change at point A is '8kg/cm ² ', the acupressure unit 13 ) is moved up and down so that the pressure by the acupressure unit 13 is maintained at '10kg/cm ² ', and even when the pressure value of the load change is '2kg/cm ² ', the acupressure unit 13 is moved up and down so that the acupressure unit ( The pressure by 13) should be maintained at '10kg/cm ² '.

That is, the change in load at each point does not reach the standard pressure.

In this case, since the reference pressure and the pressure value of the change in load at each point are different for each body, assuming that the lifting speed of the acupressure unit 13, that is, the vertical transfer speed, is the same, the lifting amount (or lowering amount) of the acupressure unit 13 ), it becomes difficult to maintain uniform acupressure.

Therefore, in the present invention, the driving speed of the acupressure unit 13, that is, the vertical transfer speed (elevation speed and descent speed) and horizontal transfer of the acupressure unit 13 as well as the amount of change in elevation of the acupressure unit 13 by using the load change amount. It is preferable to maintain a uniform pressure by adjusting the speed.

In this case, since the pressure values at points A and B have deviations from the reference pressure, respectively, '-8kg/cm ² ', '-2kg/cm ² ', assuming that the acupressure unit 13 moves up and down at the same speed , The acupressure unit 13 at point A takes more time to reach the reference pressure than the acupressure unit 13 at point B.

At this time, the difference between the reference pressure and the pressure value of the change in load at each point means the amount of elevation (ΔH _A ) (ΔH _B ) at each point.

In other words, in this case, it is difficult to maintain a uniform pressure due to the time deviation at each point.

Therefore, the vertical transfer speed of the acupressure unit 13 at point A is relatively faster than the vertical transfer speed of the acupressure unit 13 at point B, while the horizontal transfer speed of the acupressure unit 13 at point A is at point B. The acupressure force at both points can be maintained uniformly by making it relatively slower than the horizontal conveying speed of the acupressure unit 13 in .

That is, the unevenness of the acupressure force due to the time deviation caused by the difference in the pressure value at any two points can be compensated through the adjustment of the vertical and horizontal conveyance speeds of each acupressure unit 13, so that a uniform acupressure force can be maintained. there is.

In addition, when the pressure value according to the load change at any two points exceeds the reference pressure, the downward change of the acupressure unit 13 and the time deviation generated therefrom are the vertical and horizontal transfer speeds of the acupressure unit 13 It is possible to maintain a uniform acupressure force by adjusting.

In this case, the vertical and horizontal feed rates of the acupressure unit 13 mean relative speeds between the vertical and horizontal feed rates at each point.

In addition to the '10kg/cm ² 'set in this specification, the reference pressure value is provided with a pressure strength adjusting unit in the control unit so that it can be adjusted in a variety of ranges in consideration of the strength of acupressure required by the user or the degree of fatigue during massage work, in addition to '10kg/cm 2 ' It is desirable to make it possible.

Another embodiment relates to the behavior of the acupressure unit 13 according to the difference in load variation value, as shown in FIG. One case (case 1) and a case where the body curvature changes rapidly (case 2), such as when the user moves from the waist to the hip, can be assumed.

5 shows the instantaneous load change (ΔW ₁ ) (ΔW ₂ ) in each case, and in this case, it is assumed that each load change is an absolute load change independent of the reference pressure, and the acupressure unit 13 is lifted and lowered. Assuming that it is the case

In addition, it is assumed that the amount of change in load in each case is when the acupressure unit 13 moves the same horizontal movement distance.

That is, the load variation (ΔW ₁ ) (ΔW ₂ ) of each case shows a relatively large difference, and therefore, in order to maintain the same acupressure force, the lifting amount of the acupressure unit 13, the vertical movement speed and the horizontal transport speed are mutually In the relationship, compensation is required.

As shown in FIG. 5, the change in load (ΔW ₁ ) (ΔW ₂ ) in each case is “2kg/cm ² ” for case 1 and “8kg/cm ² ” for case 2,

In each case, the lifting amount of the acupressure unit 13 is relatively large in the case of 'case 2' compared to the case of 'case 1'.

In this case, when the lifting speed of the acupressure unit 13, that is, the vertical conveying speed is the same, considering the lifting amount in each case, it is difficult to maintain a uniform acupressure force because a time deviation occurs as much as the lifting amount deviation.

Therefore, in order to compensate for the time deviation (or deviation in the amount of elevation per unit time) as described above, in the case of 'case 1', the vertical conveying speed (Vv = a1) of the acupressure unit 13 is slowed down, and in 'case 2' In this case, the vertical transfer speed (Vv = a2) of the acupressure unit 13 is relatively quickly raised and lowered in contrast to 'case 1'.

At the same time, the horizontal conveying speed of the acupressure part 13 also needs to be compensated. In this case, the horizontal conveying speed of the acupressure part 13 of 'case 2' (Vh = b2) is the horizontal conveying speed of 'case 1' (Vh = Compared to b1), it is possible to keep the acupressure force uniform in each case by transferring it relatively quickly.

As can be seen from the two embodiments as described above, the pressure by the pressure portion 13 is the amount of elevation and descent of the pressure portion 13 according to the amount of load change, the vertical conveying speed of the pressure portion 13, and In the case of simultaneously controlling the horizontal conveying speed, it is possible to maintain a uniform pressure.

However, the above-described embodiment assumes an extreme situation in order to more clearly explain the behavior of the acupressure unit 13 .

Unlike this, when the change in load is very small, that is, when the acupressure unit 13 can maintain the reference pressure even without lifting and lowering, the movement in the vertical direction of the acupressure unit 13 is stopped, but it moves in the horizontal direction. The horizontal movement of the acupressure unit 13 can be maintained at a speed capable of maintaining the reference pressure.

In addition, in order to determine the behavior of the acupressure unit 13 in consideration of the load variation of the acupressure unit 13, the minimum pressure change amount for the behavior of the acupressure unit 13 is determined, and the load change amount of the acupressure based on this pressure change amount In contrast, it is possible to determine the behavior of the acupressure unit 13.

In this case, the minimum pressure change is set to '1' and '-1'.

That is, when the load variation of the acupressure unit 13 is '1' or less, or '-1' or more, the acupressure unit 13 does not rise and fall, and conversely, the load variation of the acupressure unit 13 is 1' or more , or '-1' or less, in this case, the acupressure unit 13 is raised and lowered.

In this case, since the change between the current load value and the previous load value (Sn-1) does not reach the minimum pressure change, the change between the previous load value (ie Sn-2) and the current load value (Sn) needs to be measured.

That is, when the amount of change between the load value (Sn-2) of the previous step and the load value (Sn-1) of the previous step is '1' or less, or '-1' or more, the acupressure unit 13 does not rise and fall. In this case, the load value of the previous step (Sn-1) is discarded, and the change between the current load value (Sn) and the load value of the previous step (Sn-2) is '1' or more, or '-1' 'Only when the case is below, the acupressure unit 13 may be configured to rise and fall.

This corresponds to an example indicating that the lifting and lowering behavior of the acupressure unit 13 can be determined by comparing the change amount of the acupressure unit 13 and the minimum pressure change amount.

Therefore, since it is possible to adjust the behavior of the acupressure unit 13 or the driving speed according to various setting standards, this is a matter that can be reflected in consideration of various factors during design.

In the control method of the acupressure unit 13 according to the present invention as described above, the operation is controlled by the weight sensor, and the load value sensed by the weight sensor is transmitted to a controller (not shown), and the controller includes a horizontal transfer unit, The operation of the lifting and lowering means is controlled.

In this case, the load variation value can be used either by using the variation itself or converted into a pressure value, and in this specification, the load variation value converted into a pressure value is used in consideration of the reference pressure.

In the above, the method for controlling the acupressure part for a thermal therapy device according to the present invention has been described with reference to the accompanying drawings, focusing on specific shapes and directions. It should be construed as being included in the scope of the rights of the invention.
