  However, drinks with eating and swallowing problems require individual treatment for the degree of stiffness of each patient and so on. For people with dysphagia, the beverage is thickened to reduce the risk of aspiration, but when the degree of stiffness is thin and the fluidity is high, it is difficult to match the timing with swallowing. On the other hand, if the degree of stagnation becomes too thick, adhesion will increase and conversely, swallowing will become difficult, resulting in a risk of asphyxiation. Thus, the degree of tortuosity required varies with the degree of dysphagia and the ability of the individual to swallow.

  Furthermore, it is possible to respond to the degree of stagnation and the temperature of the drink by human stirring without using a stirring device, but since the working time takes about 10 minutes, the time for other nursing and care activities is lost. It was From the above situation, it is possible to adjust the degree of tortuosity corresponding to each patient by a simple method, and to cope with the type of drink, etc., there has been a demand for a tortoise stirrer.

  Therefore, the present invention aims to provide a torrefaction stirrer capable of appropriate tortuosity corresponding to each patient and the like.

  In order to solve the above-mentioned problems, according to a first aspect of the present invention, a stirring unit is connected to a main body, a rotary drive housed in the main body, and a rotary shaft rotated by the rotary drive and stirs a target to be stirred. And a holding unit that holds the rotating shaft so as to be inclined with respect to the axial direction of the rotation shaft, and the stirring unit is a stirring surface that receives the most resistance from the stirring object when rotated by the rotation driving unit; A first side intersecting with the agitating surface, and a second side intersecting with the agitating surface and different from the first side, and the holding portion is a first wall that abuts against the first side; According to another aspect of the present invention, there is provided a filth agitator according to the first aspect of the present invention, comprising: a second wall opposed to the first wall and abutting on the second side.

  In a second aspect, the toning and stirring device described in the first aspect, wherein the holding portion sandwiches the stirring portion in cooperation with a first holding portion and the first holding portion, And a holding member configured to maintain a state in which the first holding portion and the second holding portion sandwich the stirring portion. The stirring unit is detachably attachable by removing the holding member or loosening the holding member.

  In a third aspect of the invention, it is the entangled agitator described in the first aspect or the second aspect, wherein the agitating portion is positioned at a tip end portion, opposite to the tip end portion and held by the holding portion. The holding portion is such that the center of rotation of the rotating shaft is closer to the tip end with respect to the central position of the stirring portion in the holding portion. It is characterized by holding the department.

  According to the first aspect of the invention, since the first wall and the second wall are in contact with the first side and the second side which are in contact with the stirring surface which receives the resistance, the rotation resistance at the time of stirring The displacement can be suppressed and the stirring target can be efficiently stirred. When stirring a thick stirring target with the inclined stirring unit, it is necessary to keep the stirring unit in the inclined state in the holding unit against the centripetal force since the centripetal force acts on the stirring unit. According to the present invention, since the first wall portion and the second wall portion are in contact with the first side surface and the second side surface of the agitating portion, respectively, the centripetal force is resisted and the agitating portion is maintained in the inclined state in the holding portion. be able to. In addition, since the holding unit holds the stirring unit in an inclined state, the stirring unit efficiently stirs the entire container in which the stirring target is contained, and suppresses the generation of the lump of the tori agent and makes the tori agent uniform. Can be dispersed in

  According to the second aspect of the invention, the stirring unit can be easily replaced since the stirring unit is removable by removing or loosening the holding member. As a result, it is possible to use a disposable wooden spatula or the like as the stirring unit, and it is possible to realize a hygienically good torrefaction stirrer. Moreover, since the first holding portion and the second holding portion sandwich the stirring portion by the holding member, the stirring portion can be held with a simple structure. Furthermore, since the first holding portion and the second wall portion are provided in the second holding portion, it is possible to hold the stirring portions of various shapes only by replacing the second holding portion.

  According to the third aspect, in order to hold the held portion so that the rotation center of the rotation shaft is closer to the tip end side with respect to the central position in the held portion of the stirring portion, the torque of the rotation drive portion is efficiently stirred. Can be told to the department. For example, when the center of rotation and the center position in the held portion coincide with each other, the distance between the center of rotation and the tip end is separated, and therefore a high rotation moment when stirring an agitation target having a high degree of stiffness. Is required. However, according to the present invention, since the distance between the center of rotation and the tip end is close, it is possible to rotate the stirring portion with a small torque.

  Therefore, according to the present invention, it is possible to provide a torrefaction stirrer capable of appropriately torquing corresponding to each patient and the like.

By rotating the stirring unit 6, the stirring target 8 such as a drink or the like in the container 7 into which the thickener is charged is stirred and is subjected to the thickening. Since the support shaft 3 is a square pole having a rectangular cross section, rotation of the main body 2 about the support shaft 3 is suppressed. The surrounding wall 4 is erected so as to extend upward around the back of the base portion 5 and in the left-right direction, and prevents scattering of the stirring object 8 at the time of stirring. In the base portion 5, a container 7 in which an object to be stirred 8 is placed is placed.

It is done. The control unit 20 is a microcomputer, and includes a detection unit 26, a stiffness calculation unit 27, an asymptotic determination unit 28, and an amplitude determination unit 29.

  The detection unit 26 detects an electrical detection amount such as a voltage value, a voltage duty ratio, a current value, a current duty ratio, and a rotation number of the rotation drive unit 25. The stiffness calculation unit 27 calculates the degree of stiffness (viscosity) of the stirring target 8 based on the detection result of the detection unit 26. The asymptotic determination unit 28 and the amplitude determination unit 29 calculate the electrical detection amount based on the detection result of the detection unit 26. The detailed calculation method of the degree of stagnation and the calculation of the electrical detection amount will be described later.

  As shown in FIG. 1, the control switch 21 is provided on the upper surface of the main body 2, and the control unit 20 controls the rotation of the rotation drive unit 25 based on a signal from the control switch 21. The display unit 22 is provided on the front of the main unit 2 and displays the current status and the degree of squeeze calculated by the slump calculating unit 27 in numerical values. Similarly, on the front side, a first LED lamp 22A and a second LED lamp 22B are provided, and they light up and blink according to the status of the rotation drive unit 25.

The power supply unit 24 is a dry battery, a chargeable / dischargeable lithium ion battery or the like built in the main body unit 2, and is a power supply for driving the kneading agitator 1. Alternatively, use an external power supply with a power cable.

  The rotation drive unit 25 is a motor, and the control unit 20 drives at a predetermined rotation speed by PWM control. As shown in FIG. 1, when the rotation drive unit 25 rotationally drives the rotation shaft 25A, the stirring unit 6 held by the holding unit 30 is rotated.

[Configuration of holding unit]
Next, with reference to FIG. 3 and FIG. 4, the holding structure of the stirring unit 6 in the holding unit 30 will be described.

  The stirring unit 6 is a metal, resin, or metal spatula such as stainless steel, and has an elongated flat plate shape with rounded ends at both ends. Stirring portion 6 includes tip portion 61, held portion 62 opposite to tip portion 61 and held by holding portion 30, stirring surface 6A receiving the most resistance during stirring of stirring target 8, and right side surface 6B And the left side surface 6C. The stirring unit 6 uses a disposable wooden or resin spatula or a metallic spat that can be repeatedly used after cleaning in consideration of hygiene and working efficiency. The right side 6B corresponds to the first side of the present invention, and the left side 6C corresponds to the second side of the present invention.

  As shown in FIG. 3, the holding unit 30 includes a cover 31, a first holding unit 32, a second holding unit 33, and a holding member 34. The holding unit 30 holds the stirring unit 6 by the first holding unit 32 and the second holding unit 33, and holds the stirring unit 6 by holding the first holding unit 32 and the second holding unit 33 by the holding member 34. keeping. The cover 31 covers the outer surfaces of the first holding portion 32 and the second holding portion 33, and an opening 31a is formed on the lower surface. On the inner wall in the left-right direction of the cover 31, engaging convex portions 31A that respectively protrude inward are provided.

  The first holding portion 32 is composed of a first supported portion 35 and a front wall 36, and a first groove 32a is formed between the first supported portion 35 and the front wall 36. A first engagement recess 35A that engages with the engagement convex portion 31A is formed on the side surface in the left-right direction of the first held portion 35, and a rear surface is a first holding surface 35B that contacts the stirring portion 6.

  The second holding portion 33 is composed of a second held portion 37 and a rear wall 38, and a second groove 33a is formed between the second held portion 37 and the rear wall 38. A second engagement recess 37A that engages with the engagement protrusion 31A is formed on the side surface in the left-right direction of the second gripped portion 37, and the front surface is a second contact surface 37B that contacts the first holding surface 35B.

  In the second contact surface 37 </ b> B, an engagement groove 39 which is recessed rearward and into which the held portion 62 of the stirring portion 6 is fitted is formed. The engagement groove 39 is formed to be inclined obliquely with respect to the vertical direction, and a first wall 39A in contact with the right side surface 6B and a second wall facing the first wall 39A and in contact with the left side 6C. A back wall 39C connecting the top of the first wall 39A and the top of the second wall 39B and in contact with the upper end of the held portion 62; and a back wall 39D in contact with the rear surface of the held 62 , Composed of The distance between the first wall 39A and the second wall 39B is slightly larger than the width of the stirring portion 6, and the shape of the back wall 39C is substantially the same as the shape of the upper end of the held portion 62.

  Since the shape of the engagement groove 39 is substantially the same as that of the held portion 62, the first wall 39A and the right side surface 6B abut each other, and the second wall 39B and the left side 6C abut each other. When the upper end portion of the 62 contacts the back wall 39C and the rear surface of the held portion 62 abuts the back wall 39D, the held portion 62 fits with the engagement groove 39. Since the engagement groove 39 for holding the stirring portion 6 is formed in the second holding portion 33 but not formed in the first holding portion 32, the second holding portion 33 is engaged with another shape of the engagement groove By replacing it with the formed member, various shapes of the stirring unit 6 can be used.

  The holding member 34 is a metal plate spring clip, and includes a first holding portion 34A and a second holding portion 34B facing the first holding portion 34A in the front-rear direction. The first holding portion 34A and the second holding portion 34B are separated by a predetermined distance in the front-rear direction. The predetermined distance is smaller than the sum of the thickness of the first held portion 35 and the thickness of the second held portion 37.

  Next, a method of holding the stirring unit 6 by the holding unit 30 will be described.

  The stirring portion 6 is fitted in the engagement groove 39, and the first holding surface 35B and the second contact surface 37B are brought into contact with each other to contact the stirring surface 6A and the first holding surface 35B of the held portion 62. Get in touch. The first holding portion 34A of the holding member 34 is inserted into the first groove portion 32a, and the second holding portion 34B is inserted into the second groove portion 33a. Thereby, the first holding portion 32 and the second holding portion 33 are held by the holding member 34. At this time, the first engagement recess 35A and the second engagement recess 37A coincide with each other in the front-rear direction. In this state, the cover 31 is covered, and the engagement protrusion 31A is engaged with the first engagement recess 35A and the second engagement recess 37A. Thus, the stirring unit 6 is held by the holding unit 30. When replacing the stirring unit 6, the cover 31 is removed to expose the holding member 34, and the holding member 34 is loosened or removed. A new stirring unit 6 is prepared and replaced, and the holding unit 30 is assembled in the same flow as the procedure described above.

  As shown in FIG. 4, when the stirring unit 6 is rotated by the stirring target 8 having a thick, rotation resistance is applied to the stirring surface 6A, and a centripetal force F acting on the stirring unit 6 toward the rotation center C1 works. In the holding unit 30, since the right side surface 6B and the left side surface 6C of the stirring unit 6 are held by the first wall 39A and the second wall 39B, the holding unit 6 is not displaced with respect to the centripetal force F can do.

  As shown by a dashed-dotted line in FIG. 4, the rotation center C1 of the rotation shaft 25A is offset from the center position C2 in the left-right direction of the held portion 62 when the stirring portion 6 is held by the holding portion 30. In detail, the rotation center C1 is closer to the tip portion 61 side of the stirring unit 6 than the center position C2. As a result, since the distance in the left-right direction between the tip portion 61 and the rotation shaft 25A becomes short as compared with the case where the rotation center C1 and the center position C2 coincide, the rotation torque of the rotation drive unit 25 can be efficiently It can be transmitted to the stirring unit 6.

  Assuming that the stirring unit 6 held by the holding unit 30 is a center line C3, the stirring unit 6 is inclined at an angle θ with respect to the rotation center C1. The angle θ is set such that the rotation diameter L of the tip portion 61 when the stirring unit 6 rotates is slightly smaller than the diameter of the bottom surface of the container 7. The angle θ can be arbitrarily set according to the length of the stirring portion 6 in the vertical direction and the diameter of the bottom surface of the container 7.

[Operation flow of torrefaction agitator]
Next, with reference to FIGS. 5 to 8, the operation flow of the thickening and stirring device 1 will be described.

  As shown in FIG. 1, a container 7 containing a beverage or the like to be stirred 8 is placed on the base 5. The container 7 is mounted on the base portion 5 such that the center of the bottom surface of the container 7 and the rotation center C1 of the rotation shaft 25A coincide with each other. The main body 2 is slid downward on the support shaft 3 so that the tip 61 is at a distance slightly away from the bottom of the container 7. When the tip portion 61 is spaced from the bottom surface of the container 7, the stirring of the separated space becomes insufficient, and a lump of a flocculating agent is generated, so the tip portion 61 is used as the bottom surface of the container 7 as much as possible. Get close.

  When the battery is set to the consolidating stirrer 1 or a power cable (not shown) is connected, the standby mode is set (S1). When the control switch 21 is pressed (S2: YES), the control unit 20 rotates the rotation drive unit 25 at the stirring rotational speed r1 (FIG. 7, t0 to t1). When the stirring unit 6 vigorously stirs the stirring target 8, the control unit 20 causes the rotation number of the rotation driving unit 25 to reach the stirring rotation number r1 in a time of t0 to t1 since the stirring unit 6 scatters around.

  In the present embodiment, the control unit 20 controls the rotation of the rotation driving unit 25 by PID control to reach the stirring rotation number r1. Various parameters such as Kp, Ki, and Kd in the PID control are set to appropriate values in accordance with the characteristics of the rotation drive unit 25 and the stirring target 8 or the like. As shown in FIG. 7C, when the value of the voltage duty ratio is stabilized at t1 ', the electrical detection amount taking into consideration the mechanical loss of the rotational drive unit 25 and the rotational resistance of the stirring target 8 itself by the detection unit 26 is a baseline. It is measured as (BS) and temporarily stored (S3). In the present embodiment, the voltage duty ratio is stored as the electrical detection amount of the base line. The determination as to whether or not the stirring rotational speed r1 is stabilized may be determined by the elapsed time from t1, and is determined by the rate of change of the moving average value of the voltage duty ratio detected by the detection unit 26 by the asymptotic judgment unit 28. You may The measurement of the baseline is from a few seconds to a few tens of seconds, and the first LED lamp 22A is lit during the measurement, and the user is warned not to touch the hand because the measurement is being performed.

  When the baseline measurement is completed (S4: YES), the control unit 20 sets the rotation speed of the rotation drive unit 25 to the insertion rotation speed r2 (t2). At this time, the first LED lamp 22A is extinguished and the second LED lamp 22B blinks, thereby informing the user that it is an insertion time for inserting the thickening agent. The user inserts the flocculating agent into the stirring target 8 when the stirring unit 6 is stirring the stirring target 8 at the input rotation speed r2. When the object to be stirred 8 is left standing, it tends to be lumpy, but since the stirring unit 6 is charged in a state where the object to be stirred 8 is stirred, dispersing agent disperses and it becomes difficult to form lumps. In addition, since the input rotation speed r2 is a rotation speed lower than the stirring rotation speed r1, it is possible to suppress the scattering agent from hitting the stirring portion 6 and scattering around.

  The control unit 20 maintains the rotation drive unit 25 at the closing rotation speed r2 until the control switch 21 is pressed (S6: NO). The user depresses the control switch 21 when the introduction of the thickening agent is completed. As shown in FIG. 7B, when the control switch 21 is pressed (S6: YES, t3), the control unit 20 sets the rotation drive unit 25 to the stirring rotational speed r1 (S7). At the same time, the second LED lamp 22B is turned off and the first LED lamp 22A is turned on. In addition, in addition to the coagulant, you may add additional stirring object 8 in injection | throwing-in time.

  The stirring unit 6 uniformly disperses the tonic agent by stirring the to-be-stirred object 8 to which the tonic agent has been added at the stirring rotational speed r1. In particular, since lumping easily occurs immediately after adding the thickening agent, the rotation number of the rotation drive unit 25 is immediately raised to the stirring number of revolutions r1 to diffuse the thickening agent at a stretch.

  The detection unit 26 constantly detects the voltage duty ratio of the rotation drive unit 25 as shown in FIG. 7C. The stagnation calculation unit 27 calculates the firmness degree of the stirring target 8 based on the voltage duty ratio detected by the detection unit 26 and the baseline measured in S3. In the present embodiment, the degree of firmness is evaluated by a five-step numerical value of 0 to 4, 0 being non-thick or thin thick and having low viscosity, and 4 being thick and having high viscosity and high viscosity. When the voltage duty ratio corrected at the baseline exceeds a predetermined threshold value, the corresponding numerical value is calculated as the numerical value of the degree of stagnation. In addition, the calculation method of the degree of stagnation can be calculated by various calculations according to the temperature and type of the drink. After t3, the display unit 22 displays the numerical value of the degree of stagnation calculated by the stagnation calculation unit 27. In the first embodiment, the stiffness calculation unit 27 calculates the stiffness degree based on the voltage duty ratio of the rotational drive unit 25. However, the stiffness degree is calculated based on the voltage value, the current value, the current duty ratio, or the number of rotations. Can be calculated.

  When the rotation drive unit 25 is rotating at the stirring rotation number r1, the first LED lamp 22A is on. When the user determines that the numerical value of the degree of stiffness displayed on the display unit 22 is low and the degree of stiffness is thin, the control switch 21 can be pressed to additionally load the thickening agent. When the control switch 21 is pressed again (S8: YES, t4), the control unit 20 rotates the rotation drive unit 25 at the input rotation speed r2 (S9). At the same time, the first LED lamp 22A turns off and the second LED lamp 22B blinks. The user additionally adds a thickener to the container 7 and presses the control switch 21. When the control switch 21 is pressed (S10: YES, t5), the control unit 20 rotates the rotation drive unit 25 at the stirring rotation number r1 (S11). At the same time, the first LED lamp 22A is turned on and the second LED lamp 22B is turned off. If the control switch 21 is not pressed (S8: NO), the control unit 20 displays the degree of squeezing calculated by the slump calculating unit 27 on the display unit 22 (S12). If it is determined that the numerical value of the degree of stiffness displayed on the display unit 22 is high and the degree of darkness is thick, the agitation target 8 can be additionally charged in the same manner as described above.

  The asymptotic determination unit 28 determines whether the voltage duty ratio detected by the detection unit 26 is asymptotically stable (S13). As shown in FIG. 8A, the asymptotic determination unit 28 determines that the asymptotic stability is established when the slope (rate of change) of the graph of the moving average value of the voltage duty ratio is equal to or less than a predetermined threshold. The gradual increase in the voltage duty ratio means that the thickening agent is sufficiently molecularly bound to the stirring object 8 and the degree of stiffness of the stirring object 8 is stabilized.

  The amplitude determination unit 29 determines whether the fluctuation amplitude of the voltage duty ratio detected by the detection unit 26 converges (S14). In the present embodiment, in the graph shown in FIG. 8B, the amplitude determination unit 29 determines the convergence of the variation amplitude based on the variation rate of the voltage duty ratio. The fluctuation rate is calculated by the difference between the voltage duty ratio in FIG. 8A and the moving average value. The asymptotic judgment unit 28 and the amplitude judgment unit 29 constantly monitor the voltage duty ratio from the detection unit 26 after the rotational drive unit 25 has become the stirring rotation number r1 at t3 and makes a judgment. In a state where the duty ratio does not converge, the stirring portion 6 and the dama collide with each other due to the presence of a partial dam in the stirring target 8, and the fluctuation amplitude of the duty ratio does not converge. The convergence of the voltage duty ratio means that the lumps of the tonicifying agent are sufficiently stirred by the agitating section 6 and the tonicifying agent spreads uniformly over the to-be-stirred object 8.

  When the amplitude determination unit 29 determines that the variation rate has become equal to or less than the predetermined threshold (S14: YES, t6), the control unit 20 determines that the thickening is completed, and turns off the first LED lamp 22A and the second LED lamp 22B. Is lighted, and the sound output unit 23 sounds a buzzer. The control unit 20 indicates the degree of stagnation of t6 on the display unit 22 as a numerical value (S16), and sets the rotation speed of the rotation drive unit 25 to the familiar rotation speed r3 lower than the insertion rotation speed r2 (S17).

  The stirring unit 6 stirs the stirring target 8 at a lower familiar rotation number r3, thereby removing air bubbles in the stirring target 8 and promoting slump. When the predetermined time has elapsed (S17: YES, t7), the sound output unit 23 sounds the familiar completion buzzer again, and the torrefaction stirring flow ends.

  According to such a configuration, since the first wall 39A and the second wall 39B are in contact with the right side surface 6B and the left side surface 6C crossing the stirring surface 6A where the stirring unit 6 receives resistance, stirring is performed It is possible to efficiently stir the agitation target 8 by suppressing the displacement due to the rotational resistance of When stirring a target to be stirred 8 having a thickened shape by the inclined stirring unit 6, it is necessary to keep the stirring unit 6 in the inclined state in the holding unit 30 against the centripetal force F because the centripetal force F acts on the stirring unit 6. . According to the present invention, since the first wall 39A and the second wall 39B are in contact with the right side 6B and the left side 6C of the agitating portion 6, respectively, the centripetal force F is resisted and the agitating portion 6 is inclined by the holding portion 30. It can be kept as it is. In addition, since the holding unit 30 holds the stirring unit 6 in a tilted state, the stirring unit 6 efficiently stirs the entire container 7 containing the target 8 to be stirred, thereby suppressing the generation of lumps of the coagulant. At the same time, the thickener can be uniformly dispersed.

  According to such a configuration, since the stirring unit 6 is removable by removing or loosening the holding member 34, the stirring unit 6 can be easily replaced. As a result, it is possible to use a disposable wooden spatula or the like as the stirring unit 6, and it is possible to realize a hygienically good torrefaction stirrer 1. Further, the first holding portion 32 and the second holding portion 33 maintain the state in which the stirring portion 6 is held by the holding member 34, so that the stirring portion 6 can be held with a simple structure. Furthermore, since the second holding portion 33 is provided with the first wall portion 39A and the second wall portion 39B, it is possible to hold stirring portions of various shapes simply by replacing the second holding portion 33. Become.

  According to such a configuration, since the held portion 62 is held such that the rotation center C1 of the rotation shaft 25A is closer to the tip end 61 with respect to the center position C2 of the held portion 62 of the stirring unit 6, the rotation drive unit The torque of 25 can be efficiently transmitted to the stirring unit 6. For example, when the rotation center C1 and the center position C2 in the held portion 62 coincide with each other, the distance between the rotation center C1 and the tip portion 61 is separated, and the stirring target 8 with a high degree of stiffness is agitated. In the case, a high torque is required. However, according to the present invention, since the distance between the rotation center C1 and the tip portion 61 is short, it is possible to rotate the stirring portion 6 with a small torque.

  Next, a second embodiment of the present invention will be described based on FIG. 9 and FIG. About the same composition as a 1st embodiment, the same numerals are attached and explanation is omitted.

  As shown in FIG. 9, in the consolidating stirrer 101 according to the second embodiment, a thickening agent charging unit 102 is detachably provided on the surrounding wall 4. As shown in FIG. 10, the thickening agent loading unit 102 is electrically connected to the loading completion determination unit 103 and the control unit 20. The thickening agent loading unit 102 has a storage portion 102A in which the thickening agent is stored, and a lid portion 102B, and is formed with a loading port 102a for loading the thickening agent. The feed completion determination unit 103 is a sensor provided in the thickener addition unit 102, and detects whether or not the thickener is remaining in the thickener collection unit 102. The user opens the lid portion 102B in advance and inserts a thickening agent into the storage portion 102A. When the measurement of the baseline is completed, the control unit 20 lowers the rotational speed of the rotational drive unit 25 to the input rotational speed r2 and outputs a charging signal for charging the thickening agent into the thickening agent charging unit 102.

  When the thickening agent loading unit 102 receives the loading signal, the loading port 102 a is opened by an actuator (not shown) provided in the thickening agent loading unit 102, and the thickening agent is automatically loaded into the container 7. At this time, as in the first embodiment, the stirring unit 6 stirs the stirring target 8 at the input rotation speed r2. When all the thickening agents in the storage section 102A have been loaded, the loading completion determination unit 103 detects the loading completion of the thickening agent, and outputs a loading completion signal to the control unit 20. When the control unit 20 receives the input completion signal, the control unit 20 sets the rotation drive unit 25 to the stirring rotational speed r1. After that, when the completion of the thickening is determined by the determination of the asymptotic determination unit 28 and the amplitude determination unit 29, the rotational drive unit 25 is rotated at the familiar rotation number r3 for a predetermined time to complete the consolidation.

  According to such a configuration, since the thickening agent charging unit 102 charges the thickening agent in a state in which the stirring target is stirred, it is possible to suppress the generation of lumps that are lumps of the thickening agent at the time of charging the thickening agent. In addition, since the thickener agent feeding unit 102 automatically feeds the thickener agent at a predetermined timing, the user does not have to dispense the thickener agent, and the work load can be alleviated, and for other nursing and care activities. It is possible to secure time.

  The consolidating stirrer according to the present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the invention described in the claims of the utility model registration.

  In the above embodiment, the asymptotic judgment unit 28 judges asymptotic stability (S12: YES) and the amplitude judgment unit 29 judges the amplitude convergence (S13: YES) and the completion of the thickening is judged (S14). ), Not limited to this. For example, the thickening may be completed based on at least one of the asymptotic stability of the asymptotic determination unit 28 and the amplitude convergence of the amplitude determination unit 29.

  In the above-described embodiment, the asymptotic determination unit 28 and the amplitude determination unit 29 determine the completion of the thickening, but at t3, the rotation driving unit 25 reaches the stirring rotational speed r1 and the completion of the thickening is progressed for a predetermined time You may decide

  In the above-described embodiment, the rotational drive unit 25 is rotated at the familiar rotation number r3 when the lingering is completed, but the present invention is not limited to this, and the rotation of the rotational drive unit 25 may be stopped. At this time, assuming that the familiar time has ended when a predetermined time has elapsed since the rotation drive unit 25 is stopped, a predetermined display is made on the display unit 22 and the second LED lamp 22B is turned on or a buzzer is sounded by the sound output unit 23. The user is notified of the end of the familiarization time. As a result, it is possible to provide a matching time for the thickening agent and the stirring target, thereby achieving removal of air bubbles and familiarity of the thickening.

  In the above-mentioned embodiment, although the linear-shaped disposable wooden spatula was used for the stirring part 6, it is not limited to this but arbitrary shapes can be selected. However, if the surface area of the stirring surface 6A for stirring the stirring target 8 is large, partial retention occurs to generate lumps, and if the surface area is small, sufficient stirring can not be performed. It is necessary to select the shape of the stirring section in consideration of the degree of sagging or the size of the container 7.

  In the above embodiment, the holding portion 30 can be held at various inclination angles by replacing the second holding portion 33 with a member having a different shape of the engagement groove 39, but is not limited to this. (2) A mechanism for changing the angle of the stirring unit by the ratchet may be provided in the holding unit.

  In the above-described embodiment, the degree of firmness is expressed numerically on the display unit 22. However, characters such as "light toromi", "slightly thin toromi", "intermediate solidity", "slightly thick toromi", and "deep tori" It may be represented. In addition, it may be expressed in three stages of “thin toromi”, “middle toromi” and “dark toromi”, and may be expressed in four or more stages.

  Although the buzzer is sounded by the sound output unit 23 in the above embodiment, the status may be transmitted to the user by voice. For example, at t2 in FIG. 7, it may output "Please add a thickener", and at t7, output "Torrization completed".

  In the above-mentioned embodiment, although one control switch 21 was provided in the upper surface of the main-body part 2 of the conglomerate stirrer 1, it is not limited to this. For example, the switch pressed in S2, the switch pressed in S6, and the switch pressed in S8 may be separately provided. That is, the functions of the control switch of the present invention may be distributed to a plurality of switches and provided as independent switches. Further, the position at which the control switch is provided is not limited to the upper surface, and may be provided on the side surface of the main body 2.

  In the above-described embodiment, the insertion rotational speed r2 is set to be higher than the familiar rotational speed r3, but the input rotational speed r2 and the conformable rotational speed r3 may be the same rotational speed. The stirring rotation number r1, the charging rotation number r2, and the familiar rotation number r3 can be set to arbitrary values depending on the type of the stirring target 8 or the charging agent when charging.

  In the above-described second embodiment, a sensor is provided in the thickening agent loading unit 102 as the loading completion determination unit 103, but the present invention is not limited to this. For example, the input completion determination unit may be a timer, and the input completion determination unit may output an input completion signal to the control unit after a predetermined time has elapsed since the control unit transmits the input signal to the concentration control unit.

  If a cartridge type is used in addition to a single hopper as a container for containing the thickening agent at the concentration of the thickening agent, it is possible to prepare the type and amount of the thickening agent according to the convenience of each patient and the like. In this case, although it may take some time to prepare, the implementation of thickening can prevent mistakes.
