Description

[Detailed description of the invention] (Field of industrial application) The present invention is a hot water injection device, in particular, a hot water injection device that is switched at time intervals to sequentially inject hot water with different temperatures from a nozzle or a shower opening. did,
The present invention relates to a hot water injection device suitable for application to hot water baths, physical therapy, etc.

(Prior art) In general, when living tissues become inactive due to poor blood circulation or autonomic nervous disorders, physical conditions may not be good or so-called stiffness may appear in some areas due to accumulation of accumulated fatigue. There are things to do, but
In such cases, conventional methods have been to improve blood circulation by taking a bath, and to relieve stiffness with physical therapy such as acupuncture and acupressure. These techniques attempt to activate the tissue by applying some kind of stimulus to the surface of the living tissue. By the way, the effects of such stimulation vary depending on the nature and strength of the stimulus, the nature and location of the organism receiving the stimulus, and the ability of the body to effectively accept the stimulus and contribute to the enhancement of its functions. On the other hand, in some cases, it may actually suppress the function. In other words, in the case of moderately weak stimulation below a certain level that matches the characteristics of the organism being stimulated, functions are enhanced and tissues are effectively activated, but strong stimulation above a certain level It is known that when given, it causes a suppressive effect on biological functions, even if only temporarily, and even after that, there is no choice but to leave some disturbance in the autonomic nervous system, etc.
Therefore, the stimulus given for bioactivation needs to be of appropriate strength and of a nature that can be sufficiently absorbed by the receiving organism.

(Problem that the invention aims to solve) However, in the conventional bathing mentioned above, stimulation is performed throughout the whole body at the same time and at a constant temperature. Because the whole body is placed in a On the other hand, in the case of acupuncture, strong stimulation is given, albeit only locally, and this tendency is particularly noticeable when moxibustion is applied at temperatures above the burn temperature, and some people may experience it as overstimulation. In addition to the problem of producing undesirable results, there was also the problem of requiring manual labor in this case.

In view of the above-mentioned problems, the present invention changes the hot water jet from low temperature to high temperature in stages, and applies such jets to the desired parts of the living body to provide hot water stimulation, and is designed to be used for the frail, elderly, etc. To provide a hot water injection device which can easily activate biological functions by only providing partial stimulation, even if the stimulation occurs, by sufficiently adapting to the stimulation and accepting the stimulation with ease and pleasure. With the goal.

(Means for Solving the Problems) In order to achieve the above object, the present invention selectively sets the temperature change range of the injection hot water to a range that matches the conditions of the person receiving the injection in advance. A first hot water storage tank that stores hot water at the lowest temperature and a second hot water storage tank that stores hot water at approximately the highest temperature are provided, and the water output ratio from both tanks is controlled via a control valve that is opened and closed by a control circuit. The system is configured such that hot water with different temperatures is sequentially jetted from the injection port in a stepwise manner by switching at intervals in time.

The water temperature at each stage is switched instantaneously, and for this purpose, low-temperature water and high-temperature water are mixed through an on-off valve as a control valve, and each mixing amount is controlled by a rotary valve as another control valve. It is preferable that the switching is performed under time control, and that the number of switching stages is usually two to several. When setting the temperature range from low to high temperature and the state of its change, it is important to consider the sensitivity of the living body to warm water stimulation, male and female, healthy and sick people,
Although it is not possible to set a uniform temperature due to differences in physical strength and individual differences, the minimum and maximum temperature range is approximately 20℃ to approximately 50℃, which is the temperature that the living body feels comfortable with. Set between. If it is below 20°C, it is too cold, which is rather undesirable, and if it is above 50°C, it is too hot, and both will result in discomfort or rejection.

Also, the range of temperature difference between the lowest and highest temperature is set between a minimum of approximately 5°C and a maximum of approximately 30°C. This difference is 5℃
If the temperature is lower than 30°C, the stimulation will not be increased and the desired stimulation effect will not be obtained, and if it is higher than 30°C, the stimulation effect will be too large. Furthermore, the required time interval in the step change in temperature from the cold state to the hot state is
The duration should be approximately 10 seconds to 2 minutes. If the duration is less than 10 seconds, there is no time to feel the temperature change, and biological functions will not be able to sufficiently follow the stimulus, and if it is longer than about 2 minutes, the sensation will become slow and will no longer be accepted as a stimulus. The injection water pressure shall be approximately 1.5Kg/ ^cm2 . Further, the number of injection ports may be one or multiple, and in the case of multiple injection ports, the injection may be performed from all at once, or the injection operation may be automatically switched one after another.

(Function) Thus, in order to obtain the stimulating effect on the living body by the device of the present invention, the temperature range must be determined in advance based on the minimum and maximum temperatures that suit the constitution of the person.
The hot water temperatures of the first and second hot water storage tanks are approximately set to the minimum and maximum temperatures, and first, only the hot water of approximately the minimum temperature of the first hot water storage tank is injected to remove the part where the stiffness phenomenon is occurring, preferably. Hold it against the area that will be the pressure point to be relieved. Then, after a predetermined period of time, the control circuit opens, closes, or rotates the control valve to mix predetermined amounts of hot water in the first and second hot water storage tanks so that the temperature of the injected hot water becomes a certain level higher. If this state continues for a certain period of time, the control valve is operated again by the control circuit, the mixing ratio of hot water is changed, and even higher temperature hot water is injected. After that, the same action is repeated, and the hot water temperature is increased in multiple stages by the set number of stages. After the hot water of approximately the preset maximum temperature has been injected for a predetermined time, the control valve is operated by the control circuit. The water is then returned to the initial, lowest temperature hot water injection state.

As a result, the area receiving the hot water injection does not receive strong stimulation due to large temperature differences all at once.
Since the same temperature stimulus is given in stages and for a certain period of time, it can be accepted as a natural stimulus, and the stimulus is absorbed while maintaining the balance of the autonomic nervous system, and the pleasant stimulation stimulates the autonomic nervous system, especially the parasympathetic nervous system. It can normalize work, improve blood circulation and generate vitality. In this case, since the injection pressure acts in addition to the temperature stimulation, the acupressure effect acts synergistically on the area receiving the injection, resulting in more favorable results. An injection nozzle or a shower port is used as the injection port, but when a shower port is used for the injection nozzle, it is possible to spray a wide area at one time with respect to one point.

Incidentally, if radium ore or mineral stone or the like is added to the hot water in advance to elute the components, the components will act upon injection and a synergistic effect can be further enhanced.

(Example) Hereinafter, the present invention will be further explained in detail based on the illustrated embodiment. FIG. 1 is a schematic system diagram for explaining an example of a hot water injection device according to the present invention, and FIG. 2 is a schematic block diagram of an example of a control circuit for controlling the operation of the control valve of FIG. 1; FIG.

Reference numeral 18 denotes a mixing valve as one of the control valves, and in this case, it is a three-way type, two of which are an inlet path and the other one is an outlet path, and as is known, the control circuit which will be described later Depending on the rotational position of an internal rotating member that rotates in response to an output signal, the ratio of hot water flowing from the two hot water input paths to the hot water outlet path can be changed. 19, 20,
Reference numeral 21 designates an on-off valve as a control valve, and one side of the valves 19 and 20 is connected to each of the two hot water inlet paths of the mixing valve 18, and the other side is connected to pumps 22 and 23.
The pipes are connected to the tanks 8 and 9 via the respective pipes. Further, one side of the valve 21 is directly connected to the outlet path of the mixing valve 18 by piping, and the other side is connected to the pump 22 by piping. Reference numeral 24 denotes a semi-cylindrical injection box, in which an injection port 25 connected via piping to the outlet path of the mixing valve 18 is movably disposed. A water-permeable bed 26 is formed within the box 24, and a drain valve 27 is provided at the bottom, and a circulation path 29 to the tank 1 is connected to the tank 1 through a pump 28.

Reference numeral 30 denotes a control circuit for controlling the operation of control valves, and as shown in principle as a schematic block diagram in FIG. 2, _the temperature is shown to change in three stages; T ₄ is a timer circuit that determines the duration of each stage.
The input terminal of the timer circuit _T1 is connected to the input signal terminal a via the inverter I and the NOR circuit _NOR1 , and the output terminal of the circuit _T1 is connected to the valve 21 and also via the capacitor _C1 . input terminal of timer circuit T ₂ , NOR circuit NOR ₂ , amplifier A
It is connected to a mixing valve (rotating member) 18 via. The output end of said circuit _T2 is connected to valve 1

The output end of T ₃ is also connected to valves 19, 20 and pumps 22, 23, respectively, as in the case of circuit T ₂ , and is also connected to timer circuit T ₄ and valve 18 via capacitor C ₃ . .
The output end of the circuit T ₄ is connected to the valve 20 and the pump 23
and likewise to valve 18 via capacitor _C4 , while the NOR circuit
NOR ₁ is connected to the input terminal of the timer circuit T ₁ via the inverter I.

In this way, when hot water is injected by the injection device having the above configuration, in this case, the minimum temperature of the injected hot water is 35°C, and the temperature is gradually increased in three stages of 4°C each. The hot water heated to approximately 35°C is supplied to low and high temperature water tanks 8 and 9, and is heated to 35°C by each heater 10 and 11, respectively.
℃, hot water is stored at a constant temperature of 47℃. In this state, when an input signal is input to _the input signal terminal of the control circuit 30 in FIG. Hot water is injected at a pressure of approximately 1.5 Kg/cm ² and constitutes the initial stage. Therefore, if the injection port 25 is directed toward a desired part of a person lying on the bed 26, hot water stimulation will be applied to that part. This initial injection temperature, that is, the low-temperature water measurement setting temperature of the supplied water, should be set to a level slightly lower than the body temperature of the person who normally uses it, but people with frail constitutions, the elderly, etc., are more susceptible to irritation even at low temperatures. In such cases, it is advisable to set the temperature to be lower than the above temperature. However, even in that case, the temperature should be kept at about 20°C or higher, and subsequent temperature changes should be made accordingly. As a result, the area receiving the injection receives the weakest stimulation, including the injection pressure, and enters the preparation stage, allowing it to easily and fully absorb the stimulation in its initial state.

After approximately 15 seconds, which has been set in advance, the timer circuit is activated by the operation end signal of the timer circuit _T1 .
A signal is sent to T ₂ and mixing valve 18,
The valve 21 is closed and the valves 19 and 20 are opened, and the mixing valve 18 is rotated by a certain angle so that the low temperature water side is wide open.
2 and 23 are also activated, so in the second step, high temperature water is mixed in a small ratio with low temperature water to create turbulence.
Warm water with a temperature of approximately 39℃ gushes out. In the second stage, if the operating time of the timer T ₂ is set in advance to about 12 seconds, after that time, the timer circuit T ₃ is activated to further rotate the mixing valve 18 by a certain angle from the above state, and the high-temperature water is heated. The third stage is formed by increasing the mixing ratio of the water and injecting hot water at a temperature of about 43°C, which has been increased by about 4°C. Similarly, after continuing this state for about 12 seconds, the timer circuit
By the operation of T ₄ , the mixing valve 18 is further rotated, and the valve 20 is opened and the pump 2 is rotated.
3, close the other valve 19 and pump 2.
2 is deactivated, in the fourth stage, high-temperature water of about 47°C from the high-temperature water tank 9, which has risen by about 4°C, is directly injected, and the highest temperature hot water injection reaches about 40°F.
It takes place for 12 seconds. Therefore, if hot water is heated step by step from the second stage to the fourth stage and is sprayed for a certain period of time, the tissue will be sufficiently stimulated by increasing the temperature at each stage for a certain period of time. The body absorbs it effortlessly as if adapting to it, accepts it as a pleasant stimulus without showing any rejection reaction, and in the final stage, when it receives a jet of relatively high-temperature hot water, its functions are further enhanced. Blood circulation will be increased and tissues will be more activated.
Note that the injection port attached to the mixing valve 18 may be a single-hole nozzle or may be a multi-hole shower port. If you use it as a shower spout, you can stimulate a relatively wide area at the same time.

If the injection operation is continued after the injection of the highest temperature water, after approximately 12 seconds of injection of the highest temperature water, the timer circuit T 1 will be activated again via the NOR circuit NOR ₁ in response to the operation end signal of the timer circuit _{T 4} . The control circuit 30 returns to the initial stage and repeats the above action, so if the injection port is moved to another different part during the injection stage after returning to the initial stage, the above action will be performed again at that part. action will take place.

The hot water injected in the injection box 24 and collected at the bottom is returned to the main hot water storage tank 1 via the circulation path 29 by the pump 28. At this time, pass it through a filter as appropriate. Further, in the above embodiment, the case where the temperature of the hot water in the main hot water storage tank 1 was set to the minimum temperature of about 35°C was explained.
As shown by the dashed line in the figure, if a cooling block 31 is disposed between the main hot water storage tank 1 and the low temperature water tank 8 so that water can flow from the cooling water tank 6, the cooling block 31 can be installed between the main hot water storage tank 1 and the low temperature water tank 8. In water supply,
It becomes easy to maintain the temperature of low-temperature water, which is convenient when a large amount of hot water is to be injected. Furthermore, radium ore, mineral stones, etc. may be added to the main hot water storage tank 1 in advance, and the components may be eluted, or natural salt may be added to the moxa extract excluding the santonin component to create an aqueous solution with a concentration of approximately 0.9%. If used as a compound, a more favorable synergistic effect can be obtained.

Furthermore, the present invention is not limited to the configuration of the embodiment described above, and the configuration of mixing low and high temperature water, the control circuit, etc. may be implemented by other different means, and the injection block may also be of the bed type or seated type. It goes without saying that the present invention can be modified in various ways within the scope of the invention, for example, the ejection ports may be installed at multiple locations in advance and the ejection locations may be sequentially changed.

(Effects of the invention) As described above, according to the hot water injection device of the present invention, hot water with the lowest temperature and hot water with the highest temperature in the required temperature change range are prepared in advance, and the hot water is heated at a predetermined time interval. By changing the mixing ratio of hot water and spraying hot water with gradual temperature changes, it is easy to raise the temperature in stages, and if this is applied to warm water baths for living organisms, physical therapy, etc. With a gradual temperature rise, the area receiving the injection sufficiently adapts to the temperature after each stage of change before receiving the next stage of temperature stimulation, so it is accepted as a natural and extremely pleasant stimulation, and as a result, blood circulation is improved. It is promoted well, the balance of the autonomic nervous system is maintained well, and in particular the function of the parasympathetic nervous system is normalized and the tissues of the body are activated, so it is extremely effective in recovering from whole body fatigue and relieving local stiffness. It has the characteristic of being objective.
