Abstract

<P>PROBLEM TO BE SOLVED: To provide a liquid type massage apparatus which makes a person in need of care or a user clearly recognize that changes of the operation state caused by controlling the temperature of a liquid for spraying do not mean abnormal situations. <P>SOLUTION: The liquid for spraying in a main body housing 1 is sprayed to a supporting sheet 2 from spraying nozzles 11a-f by a pump. The liquid for spraying is cooled by the air blowing action of a cooling fan 22 when passing through a radiator 20. When a detected temperature Ta of the liquid for spraying which is detected by a temperature sensor 41 is greater than a set temperature T set manually, the liquid for spraying is cooled by activating the cooling fan 22. In a case of an unusually high temperature in which the detected temperature Ta is greater than the set temperature T by a prescribed degree, the operability of the pump is forced to reduce, and a speaker gives an alarm not to turn off a power switch 31. When the detected temperature Ta is lower than the set temperature T by a prescribed degree, the pump is automatically operated to increase the temperature (preheat) the liquid for spraying, and the speaker gives an alarm telling that the pump is under operation. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a liquid massage apparatus.

  Some massage apparatuses that massage the human body utilize liquid ejected from an ejection nozzle, that is, an ejection liquid. In this type of liquid massage device, for example, the upper opening of the main body housing is covered with a support sheet, and the liquid for spraying is sprayed from the spray nozzle disposed in the main body housing toward the lower surface of the support sheet. By doing so, the user lying on the support sheet is stimulated.

  There are two types of the liquid massage device according to the difference in the way the user supports. The first type, as shown in Patent Document 1, is a type in which the main body housing is filled with the jetting liquid, that is, the type in which the jetting liquid in the main body housing has no free surface, The weight of the user on the support sheet is received by the jetting liquid, which is called a so-called water bed type.

  Further, as shown in Patent Document 2, the liquid massage device of the second type has a lower level of the jetting liquid in the main body housing than the jet nozzle, so that The jetting liquid has a free surface, that is, a type in which an air layer is interposed between the liquid level of the jetting liquid in the main body housing and the support sheet (in the second type, Sometimes called shower nozzle method). In this case, the liquid for injection stored in the bottom of the main body housing is pumped up by the pump, injected from the injection nozzle, falls after colliding with the support sheet from below, and is supplied to the injection nozzle again. become.

Further, Patent Document 3 discloses a technique that can change the amount of the jetting liquid in the main body housing, that is, the height of the free surface of the jetting liquid in the main body housing. Patent Document 4 discloses a rotary type in which an injection nozzle is rotated around a predetermined axis by using an injection pressure from the injection nozzle.

  By the way, it is desired that the jetting liquid has an appropriate temperature range preferable for the user. On the other hand, the temperature of the jetting liquid is gradually raised by the operation of the pump that supplies the jetting liquid to the jet nozzle. For example, when the pump is operated for a long time, the temperature of the jetting liquid is abnormal. It can become so hot. In order to prevent such a jetting liquid from becoming too high, the jetting liquid is appropriately cooled by an electric cooling device. Normally, the cooling device is electrically operated and is operated on the assumption that the power switch is turned on.

  When the temperature of the jetting liquid becomes abnormally high, it is considered to forcibly reduce the operation capacity of the pump so that the temperature of the jetting liquid does not increase any more. However, if the operating capacity of this pump is forcibly reduced, the caregiver or user will misunderstand that some abnormality has occurred in the device and the power switch will be turned off for safety. It will be easy. In this way, when the power switch is turned off, the cooling device is forcibly stopped, and it is no longer possible to actively cool the jetting liquid that is abnormally too hot by the cooling device. The operation of the pump cannot be resumed until the temperature of the jetting liquid naturally decreases to a predetermined temperature (the time during which massage treatment cannot be performed becomes longer).

  On the other hand, for example, in the cold season such as winter, the jetting liquid becomes considerably low in temperature. For this reason, it is desired to positively warm the jetting liquid in advance before treatment, that is, to perform preheating. Become. In order to perform the heating of the jetting liquid, that is, preheating without using a separate heater, it is considered that the pump generates heat by operating the pump that supplies the jetting liquid to the jet nozzle. (Preheating is performed by operating the pump). In this case, when the temperature of the jetting liquid becomes lower than the predetermined temperature, the pump is automatically started. However, caregivers and users are surprised at the start of the automatic operation of the pump, It becomes easy to cause a situation where it is misunderstood that some kind of abnormality has occurred.

  The present invention has been made in view of the circumstances as described above, and its purpose is that the change that occurs due to the temperature control of the jetting liquid is not an abnormality of the device for the caregiver or the user. It is an object to provide a liquid type massage device that can clearly recognize the above.

  According to the above solution, when the liquid for injection becomes too hot and the operating capacity of the pump is reduced, an alarm is given so as not to turn off the power switch. This will prevent the situation. As a result, the jetting liquid can be quickly cooled by the cooling device, and can be promptly returned to a state where treatment can be resumed. In particular, since the alarm is performed by voice, it is clear that the content of the alarm is transmitted to the surrounding people more securely than when the alarm is displayed on the display screen (visual alarm). It is preferable in making it recognize.

Therefore, when the pump is operated for treatment after that, the ejection liquid Is preferable in preventing the situation where the temperature becomes too high at an early stage.

  The greater the degree that the detected temperature becomes lower than the predetermined temperature, the greater the operating capability of the pump can be (corresponding to claim 9). In this case, it is preferable to raise the temperature of the jetting liquid to a predetermined temperature as quickly as possible. Further, since the operation capability of the pump is reduced as the actual temperature of the jetting liquid approaches the predetermined temperature, it is preferable for reliably preventing the temperature from rising beyond the predetermined temperature.

Can do.
According to the invention described in claim 12, the liquid massage device can be of a type in which a widespread user receives a massage in a lying posture.

  1 and 2, a main body housing 1 is fixed and installed on a frame F, and the main body housing 1 is formed in a long and narrow tank shape, for example, by fiber-reinforced plastic, with only the upper part opened. The main body housing 1 is disposed substantially horizontally, and its upper opening 1 a is liquid-tightly covered with a support sheet 2. On the support sheet 2, a user (patient) M receiving massage is held (supported) in a lying posture (a lying posture) such as a chin. That is, the support sheet 2 is sized such that the user M can be supported at least in a supine state. The support sheet 2 is fixed so that the peripheral edge thereof is liquid-tight to the peripheral edge of the main body housing 1 (the upper opening 1a thereof). The support sheet 2 may be formed by only a thin elastic member such as rubber as a whole, or includes reinforcing fibers therein to secure strength, and further the weight of the user M. An appropriate structure such as a structure in which a net-like member excellent in supporting strength and a soft sheet material made of silicon rubber or the like laid on the net-like member are stacked can be used.

  In the main body housing 1, a jetting liquid (usually hot water) is stored as a massage liquid. In the embodiment, the main body housing 1 is filled with the jetting liquid (injected in the main body housing 1). In this state, the weight of the user M acting on the support sheet 2 is received by the jetting liquid in the main body housing 1. The present invention is not limited to the case where the main body housing 1 is filled with the jetting liquid, but may be a type in which the jetting liquid has a free surface in the main body housing 1.

  A plurality of injection nozzles 11 a to 11 f are fixed to the bottom of the main body housing 1. The injection nozzles 11 a to 11 f are directed to the following position with respect to the user M lying on the back on the support sheet 2. That is, only one injection nozzle 11a is provided and directed to the neck of the user M. A pair of right and left spray nozzles 11 b are provided and directed to the shoulder portion of the user M. Only one injection nozzle 11c is provided and directed to the waist of the user M. A pair of right and left spray nozzles 11d to 11f are provided, 11d is directed to the user M's hip, 11e is directed to the user's M thigh, and 11f is directed to the user's M calf. . In the embodiment, each of the injection nozzles 11a to 11f has an injection hole formed in the eccentric part of the hollow body that can rotate about the vertical axis, and the reaction force of the liquid for injection injected from the injection hole is a hollow body. Is set to have a tangential component. As a result, when the ejection liquid is ejected from the ejection holes, the hollow body is rotationally driven by the reaction force of the ejection pressure, and the ejection liquid ejected from the ejection holes turns toward the inner surface of the support sheet 2 while turning. Will be injected. The injection nozzle may be fixed, or may be attached to a carriage that is driven to run in the longitudinal direction of the main body housing 1 so that the injection nozzle can be moved in the longitudinal direction of the main body housing 1. In addition, it is possible to adopt a structure in which the injection nozzle is appropriately displaced, such as moving the injection nozzle in the left-right direction of the main body housing 1.

  A pump 12 is disposed around the body housing 1 (not shown in FIG. 2). As shown in FIG. 3, the suction port of the pump 12 communicates with the bottom of the main body housing 1 through the suction pipe 13. Further, the common discharge pipe 14 connected to the discharge port of the pump 12 is branched into a plurality of branch discharge pipes 14a to 14g, and the branch discharge pipes 14a to 14f are individually connected to the respective injection nozzles 11a to 11f ( The branch discharge pipes 14b and 14d to 14f are set two by two because the corresponding injection nozzle has a pair of left and right). The branch discharge pipe 14g is used for a radiator, which will be described later, and has a smaller diameter than the branch discharge pipes 14a to 14f used for the injection nozzle. The jetting liquid in the main body housing 1 sucked by the pump 12 is jetted toward the lower surface of the support sheet 2 from the jet nozzles 11a to 11f, and massage for the user M is performed. The branch discharge pipes 14a to 14f are respectively connected with electromagnetic adjustment valves 15a to 15f (the adjustment valves 15b and 15d to 15f are set two by two because the corresponding injection nozzle has a pair of left and right. It is possible to individually change the injection pressure (injection amount) from the injection nozzles 11a to 11f by individually adjusting the opening degree of each of the adjustment valves 15a to 15f. Further, the operation capacity of the pump 12, that is, the supply pressure (supply amount) of the injection liquid to the injection nozzles 11 a to 11 f can be adjusted by the inverter 16.

  The branch discharge pipe 14g finally constitutes a circulation system path opened at the bottom of the main body housing 1, and a radiator 20 is connected to the branch discharge pipe 14g. The jetting liquid supplied from the branch discharge pipe 14g to the radiator 20 flows through the radiator 20 and then returns to the main body housing 1 again. As shown in FIG. 2, the radiator 20 faces an air suction port 21 a formed in a decorative plate 21 that covers the periphery of the main body housing 1 and the frame F, and is electrically driven on the back side of the radiator 20. By operating the cooling fan 22 of the type (the driving motor of the cooling fan 22 is indicated by reference numeral 22a), the air sucked from the suction port 21a passes through the radiator 20, and the air and the air flowing through the radiator 20 are injected. Heat is exchanged with the liquid, and the jetting liquid is cooled.

  In FIG. 3, reference numeral 30 denotes a power source (for example, AC 200V commercial power source), and the inverter 16 is connected to the power source 30 via a manually operated power switch (main power switch) 31. The cooling fan 22 is connected to the inverter 16 via an electromagnetic switch 32. That is, the inverter 16 is shared by the pump 12 and the cooling fan 22, and the operating frequency of the pump 12 and the cooling fan are changed by changing the output frequency of the inverter 16 when the switch 32 is turned on. Thus, the operation capacity of 22 (the cooling capacity of the radiator 20) is changed at the same time.

  In the figure, U is a controller as a control means configured using a microcomputer, and this controller U is connected to a power source 30 via an AC / DC conversion circuit 33. The controller U bypasses the power switch 31 and is always connected to the power supply 30. The controller U receives signals from various switches S1 to S4 that are manually operated on the operation panel SP. The switch S1 is for switching between the standby mode and the treatment mode. The switch S2 is for setting the set temperature of the jetting liquid. In the embodiment, for example, the switch S2 is selected from three temperatures of 30 degrees C, 35 degrees C, and 40 degrees C. Yes. The switch S3 is a start switch, and is turned on under the condition that the treatment mode is selected, whereby the pump 12 is started to operate with an operation capacity (for example, 40 to 50 Hz) suitable for treatment. The switch S4 sets a time for performing massage. When the standby mode is selected by the switch S1, the pump 12 is appropriately operated for preheating described later.

  The controller U receives the detected temperature detected by the temperature sensor 41 that is disposed in the main body housing 1 and detects the temperature of the jetting liquid. Further, the controller U outputs a signal for displaying various types of information on the display screen 42 provided on the operation panel SP, and also outputs it to a speaker 43 for performing a sound alarm. In addition, although the speaker 43 is arrange | positioned on the upper surface of a liquid massage device, for example, the position which can be heard well by those who are around (refer FIG. 1), it can be arrange | positioned in appropriate positions, such as a side surface of an apparatus. The operation panel SP is also arranged at a position where it can be easily operated and visually observed.

  Next, control of a portion related to the temperature of the jetting liquid in the control contents by the controller U will be described with reference to the flowcharts of FIGS. 4 and 5 show the control contents in the treatment mode, FIGS. 4 and 6 show the control contents in the standby mode (FIG. 4 is for common use of the treatment mode and the standby mode), and the following In the description, Q indicates a step.

  First, in Q1 of FIG. 4, the set temperature T set by the switch S2 and the temperature of the jetting liquid detected by the temperature sensor 41, that is, the detected temperature Ta are read. Next, at Q2, it is determined whether or not the detected temperature Ta is higher than, for example, 45 degrees C (corresponding to the second predetermined temperature in the claims), which is an abnormally high temperature. If the determination in Q2 is YES, an error code indicating that the water temperature is abnormal is displayed on the display screen 42 in Q3. Next, at Q4, the pump 12 and the cooling fan 22 are operated at the lowest frequency (28HZ in the embodiment) to cool the jetting liquid. That is, the operation capacity of the pump 12 is sufficiently smaller than the operation capacity for treatment, and the injection liquid circulates through the radiator 20 while suppressing the temperature rise of the injection liquid due to the heat generation of the pump 12. Will do. The jetting liquid circulating in the radiator 20 is cooled by exchanging heat with the outside air blown by the cooling fan 22 and then returned to the main body housing 1. In this way, cooling of the jetting liquid proceeds. After Q4, an alarm is given by the speaker 43 at Q5. The contents of this alarm are “not to turn off the power switch 31”, “notice that the pump 12 is stopped”, and “notice that the water temperature is abnormally high”, and particularly “do not turn off the power switch 31 for cooling. It is preferable to give an alarm including the reason why the power switch 31 should not be turned off.

  After Q5, it is determined in Q6 whether or not the detected temperature has become 40 ° C. or less (corresponding to the maximum set temperature by the switch S2). If the determination in Q6 is NO, the process returns to Q3 and the process for cooling the jetting liquid is continued. If YES in Q6, the pump 12 and the cooling fan 22 are stopped in Q7.

  When the treatment mode is selected, after Q7 or when the determination in Q2 is NO, the process proceeds to Q11 in FIG. In Q11, it is determined whether or not the detected temperature Ta is equal to or lower than the set temperature T. If the determination in Q11 is NO, in Q12, the switch 32 for the cooling fan 22 is turned on, and when the pump 12 is operated, the cooling fan 22 is immediately put into a standby state. After Q12, in Q13, the operation of the pump 12 is started on the condition that the start switch S3 is turned on. When the operation of the pump 12 is started, the cooling fan 22 is also started to operate (the switch 32 is turned on by the process of Q12). After Q13, it is determined in Q14 whether or not the detected temperature Ta is equal to or lower than the set temperature T. If the determination in Q14 is NO, the process returns to Q12. If YES in Q14, the cooling fan 22 is stopped in Q15. After Q15 or when YES in Q11, the process returns to Q1 in FIG.

  As described above, when the treatment mode is selected, control of the temperature drop when the liquid for injection becomes abnormally high (corresponding to FIG. 4) and for injection when the pump 12 is operated for treatment. Temperature control (corresponding to FIG. 5) is performed so that the liquid does not rise excessively from the set temperature T. In the case of the control corresponding to the abnormally high temperature in FIG. 4, in the embodiment, each of the regulating valves 15 a to 15 f is fully opened.

  FIG. 6 shows the control contents when the standby mode is selected, and shows the control contents after the control of FIG. 4 is performed. In FIG. 6, first, in Q21, four threshold temperatures of TA, T, TC, and TD are set according to the set temperature T. The threshold temperature TA is set to a temperature 3 degrees C lower than the set temperature T, the threshold temperature TB is set to a temperature 5 degrees C lower than the set temperature T, and the threshold temperature TC is set to a set temperature The temperature is set 6 degrees C lower than T, and the threshold temperature TD is set 7 degrees C lower than the set temperature T. Specifically, when the set temperature T is set to 40 degrees C, the threshold temperature TA is 37 degrees C, the threshold temperature TB is 35 degrees C, and the threshold temperature TC is The temperature is 34 degrees C and the threshold temperature TD is 33 degrees C.

  The threshold temperatures TA and TB are for setting hysteresis between the operation and stoppage of the pump 12 for preheating, and the detected temperature Ta is set while the pump 12 is stopped. The operation of the pump 12 is started when the temperature becomes lower than the threshold temperature TB, and the pump 12 is stopped when the detected temperature Ta becomes equal to or higher than the threshold temperature TA while the pump 12 is operated for preheating. Is done. The operating capacity of the pump 12 for preheating is increased (higher) as the detected temperature Ta is lower. The threshold temperatures TC and TD are threshold values for changing the operating capacity of the pump 12. Used.

  After Q21 described above, it is determined in Q22 whether or not the detected temperature Ta is equal to or lower than the threshold temperature TB. If the determination in Q22 is YES, it is determined whether or not this is the first operation after startup. When the determination in Q24 is YES, in Q24, an alarm to the effect that the operation of the pump 12 is started for preheating is performed by a display on the display screen 42 and an audio alarm from the speaker 43. . This screen or voice alarm may be a simple alarm, for example, “the pump is operating”, or “the pump is operated to perform preheating”, and the reason for operating the pump is also attached. It can also be an alarm.

  If NO in Q23, the pump 12 for preheating has already been operated. At this time, in Q25, an alarm indicating that preheating is in progress is displayed on the display screen 42. It is performed by voice using the speaker 43. The alarm at Q25 may be an intermittent alarm (for example, in 30 seconds) since pre-heating is being performed and caregivers and users M in the surrounding area are not as uncomfortable as when pre-heating is started. About once, a warning that “the pump is being operated” or “the preheating is being performed” and that “the pump is being operated for preheating” is further carefully issued.

  After Q24 or Q25, it is determined in Q26 whether or not the detected temperature Ta is equal to or lower than the threshold temperature TD. When the determination in Q26 is YES, in Q27, the pump 12 performs the maximum operation capacity (operation at 50HZ in the embodiment). If NO in Q26 or after Q27, it is determined in Q28 whether the detected temperature Ta is higher than the threshold temperature TD and lower than TC. When the determination in Q28 is YES, in Q29, the pump 12 is operated with an operation capacity smaller than the operation capacity in Q27, for example, 48HZ. If NO in Q28 or after Q29, it is determined in Q30 whether the detected temperature Ta is higher than the threshold temperature TC and lower than TB. When the determination in Q30 is YES, in Q31, the pump 12 is operated with an operation capacity smaller than the operation capacity in Q29, for example, 40HZ.

  If NO in Q30 or after Q31, it is determined in Q32 whether or not the detected temperature Ta is equal to or higher than the threshold temperature TA. If the determination in Q32 is NO, the process returns to Q21, and the operation of the pump 12 is continued for preheating until the detected temperature Ta becomes equal to or higher than the threshold temperature TB. If YES in Q32, the process returns to Q1 in FIG. 4 because the preheating has ended.

  As described above, in the standby mode in which preheating is performed, the pump 12 is operated for preheating when the detected temperature Ta is lower than the predetermined temperatures (TA, TB) set to temperatures lower than the set temperature T. Is called. At this time, by setting hysteresis such as TA and TB as the threshold temperatures, it is possible to prevent the pump 12 from repeatedly starting and stopping due to preheating. Further, the lower the detected temperature Ta is, the higher the operating capacity of the pump 12 is, and the temperature of the jetting liquid is increased as quickly as possible to the vicinity of the set temperature T. In addition, the change of the driving capability of the pump 12 according to the detected temperature Ta may be set to three or more steps, or may be changed steplessly, and the driving capability is not changed. It can also be maintained. In the case of the temperature control for preheating in FIG. 6, in the embodiment, any four of the total of ten regulating valves 15 a to 15 f are fully opened, and the other six regulating valves are fully opened. Closed.

  Although the embodiment has been described above, the present invention is not limited to the embodiment, and can be appropriately changed within the scope described in the scope of claims. For example, the invention includes the following cases. . The main body housing 1 is not limited to a bed type, but may be of an appropriate type such as a chair type (for example, a seat portion as a massage surface or a backrest portion as a massage surface). The cooling device is not limited to an air-cooling type, and an appropriate type such as one using a refrigeration cycle can be used.

  A pump for circulating the jetting liquid to the radiator 20 is provided separately from the pump 12 for the jet nozzle, and an inverter for changing the operating capacity of the cooling fan 22 is used for changing the operating capacity of the pump 12. The inverter 16 may be provided separately and independently. In this case, at the time of the processing in Q3 to Q5 in FIG. 4, the operation capacity of at least the cooling fan 22 is maximized while the operation of the pump 12 is stopped so that the cooling capacity of the radiator 20 is maximized. It is preferable to operate the radiator pump (the operation capacity that maximizes the cooling capacity may be selected based on the balance between the heat generation and the circulation amount of the jetting liquid).

  The alarm may be performed only by the speaker 43. In addition, an alarm (or guidance) using at least one of the display screen 42 and the speaker 43 may be performed as follows, for example. When the treatment start switch S3 is turned on, guidance that “treatment has started” and in addition to this guidance that “slightly open your legs and drain your body” are given. When in the standby mode, the guidance “is in standby” is performed. At the stage where preheating has been completed, the guidance “Please press treatment switch to treat” is given. When any abnormality occurs in the device, guidance is given that “an error has occurred”. When various sensors or water levels are abnormally low, an alarm is issued saying "An error has occurred, please call a service person", or when various valves are abnormal, an error code on the display screen is displayed to the service person. Please contact me ". At the time of abnormally high temperature of various devices, “Turn off the power and report the error code on the display screen to the service person”. At the time when the treatment time has passed, a guidance “treatment has ended” is given, and in addition, a guidance “slowly get off the instrument” is given. When the voltage of the power supply 30 drops abnormally, an alarm “Power supply voltage is falling” is given. When the temperature of the pump 12 becomes too high, guidance is given to “limit the strength of the pump”. Of course, the object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage.
