Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field J] The present invention relates to a shower device that reheats and repressurizes water jetted from a shower for circulation.

[Background Art] Showers have generally been used as a convenient alternative to bathing to cleanse the skin.

However, as social needs for health promotion have increased, there has been a growing trend to proactively utilize the warming effect of skin stimulation in addition to the cleansing effect of showering. The thermal effect of a shower is generally known to dilate skin blood vessels and increase blood flow, promoting substance metabolism, relieving muscle stiffness, recovering from fatigue, and alleviating mental and physical tension. ing. On the other hand, if we change the rhythm of the sympathetic and parasympathetic nerves in the autonomic nervous system by stimulating the water pressure and changing the water temperature during a bath, blood vessels will repeat expansion and contraction as appropriate, and the various functions of the autonomic nervous system will be activated. It can be activated, and beauty effects can also be expected.

However, in order to actively exert the aerobic effect that relieves stress and lack of exercise and the beauty effect of skin stimulation by activating the blood flow to internal organs and muscles, the shower device must be able to produce as much hot water as possible. It is desirable to have the function of a body pine surge to control the injection pressure and temperature to an appropriate level.

Based on the experimental results of the creator of this invention, the following conditions were confirmed for a comfortable body shower.

(a) It is desirable that the injection nozzle has a plurality of injection ports and is arranged so as to effectively hit the hip of the human body, and for this purpose, it must be able to supply hot water at a rate of 501/min or more.

(b) The injection pressure of the nozzle can be adjusted to suit the stimulation force C of 1.5 Kg7cm2.

(C) Adjust the water temperature to your preferred temperature around 40℃.
! ! What you can do.

However, conventional shower devices have the following drawbacks.

(b) A storage type water heater is preferable to supply a large amount of hot water at once from 1 m of water supply, but generally it goes through a pressure reducing valve, so the pressure is reduced to about 0.6 kg/am", which causes irritation as a body pine surge. Weak effect.

(b) Running costs are high because the energy costs and water resources required for heating are wasted because the hot spring water is discharged.

(c) In order to alleviate these drawbacks, if a system is adopted in which the injected water is recirculated, the temperature of the hot water gradually decreases due to heat radiation, but in this case, it is difficult to adjust the hot water temperature.

[Purpose of the invention] The present invention has been made in view of the above points, and the purpose of the present invention is to be able to adjust a large amount of hot water to an appropriate temperature and pressure and spray it under pressure, and also to be able to reuse it. To provide a circulation type shower device which can be circulated and supplied economically and can enhance the function as a body massager.

[Disclosure of invention] Circulating shower of this invention! The device is a circulating hot water storage W! that stores the jetted water from the shower box A as circulating water! 5
and pressurizing device B that pressurizes the circulating water, and the pressurized circulating water supplied via these is connected to the hot water supply 1f.
The temperature at which the high temperature water obtained via the heating device C such as 11 is mixed is adjusted by adjusting the opening of the valve. The shower box A is characterized by having a body injection nozzle 4 connected to a valve D with a regulating function and spouting the temperature-regulated circulating water, and by being configured as described above. This solves the drawbacks of the conventional example.

The present invention will be explained in detail below with reference to Examples.

First, the embodiment shown in FIG. 1 will be explained. There is a circulating storage VHT at the bottom of the shower box A, which is large enough for a person to stand in.
lf! 5 is arranged so that the jet water used in the shower box A flows into the circulation hot water storage tank 5 and accumulates therein. The initial water required for circulation is high-temperature water from a hot water supply Plii as a heating device and cold water from a water supply device 2, which are adjusted to an appropriate temperature with a thermo-mixing valve 3, and are injected from an injection nozzle 14 at the top of the shower box A. will be supplied. The hot water stored in the circulation hot water storage tank 5 is confirmed to have reached the water level necessary for circulation by the pump using a water level detector, etc., and is taken from the water intake white 15 and pressurized by the circulation pump 8 as the pressurizing device B. The body injection 7 is
It is injected from X Le 4. For showering, spray nozzle 14
, 4 by adjusting the valve 7 at hand, the amount of water can be adjusted and the injection pressure can be adjusted as appropriate. Of course body injection nozzle 4
If you close the valve 7 at hand and then spray only from the spray nozzle 14, you can take a shower with clean water (city water).
When the hand valve 7 of the injection nozzle 14 is closed and the hand valve 7 of the body injection nozzle 4 is opened, a body shower can be performed using only the circulating water, and when both hand valves 7 are closed, a shower can be performed using both water. The recirculated water falls from the floor of the shower box A, is temporarily stored in the circulation storage 1#, 'MJ5, is again pressure-fed by the circulation pump 8, passes through the thermomixing valve 6a, and is sent to the body injection nozzle 4. sent to. To compensate for the temperature drop due to heat radiation in this process, the hot water piping side 9 of the thermomixing valve 6a is replenished with high temperature water from the water heater 1, and the temperature is raised to the temperature set by the thermomixing valve 6a. The circulating water is filtered by a filter 11 to prevent dirt in the jet water and clogging of the circulation pump 8, piping, and body injection nozzle 4 with foreign matter. An amount of circulating water equal to the amount of high-temperature water supplied for heating is discharged from the over pipe 12 of the circulating hot water storage tank 5 . At this time, scales and the like floating on the surface of the circulating hot water storage tank 5 are released to prevent the circulating water from becoming contaminated due to circulating use. In addition, the circulating water becomes contaminated with secretions from the epidermis of the human body in the early stages of use of a shower device, and the temperature of the circulating water decreases in proportion to this soiling (because the shower circulation path is colder). Therefore, a large amount of high-temperature water is supplied to the thermo-mixing valve 6a, and only the supplied amount is discharged as overwater 70, and floating substances such as sebum are discharged, thereby reducing the pollution of the circulating water. After taking a shower, hot water is discharged from the outlet 13 at the bottom of the circulating hot water tank 5. In this embodiment, the circulating hot water tank 5 is integrally provided at the bottom of the shower box A, which requires less installation space, but it may be separated from the viewpoint of installation conditions, maintenance and inspection, etc. . In addition, the thermo mixing valves 3 and 6a have a diaphragm-type wax element that senses temperature changes even when the water and hot water supply pressure changes, and has a built-in thermostub HFJ structure that self-controls the valve opening on the water and hot water supply sides. A regulating valve is appropriate.

Next, the embodiment shown in FIG. 2 will be described. In the case of this embodiment, the main structure is the same as that shown in FIG. 1, but an electric mixing valve 6b is used in place of the thermomixing valve 6a as the function-equipped valve D with temperature llI4lI4. In other words, in the case of a thermomixing valve, the thermowax element automatically controls the valve opening y411i on the hot water side and the water side, whereas 1. The aim is to enable system control of the entire circulating shower device by electronically controlling valve opening adjustment. This electric mixing valve 6
b detects the temperature with a temperature sensor 17 such as a thermistor on the secondary side of the electric mixing valve 6b, processes the signal with a converter 18, and then uses the difference from the set temperature with the control panel 19 to open the electric mixing valve 6b. Adjust the hot water temperature by giving feedback to the temperature of 1111 degrees. In the embodiment shown in FIG. 3, an electric flow rate control valve 6c is used as the temperature WI4 regulating valve D. A high temperature water piping route from the hot water supply m, 1 is connected to the circulating water piping route via an electric flow rate control valve 6c,
A buffer zone is provided at the confluence point 20 of the circulating water and high-temperature water to improve the mixing of the hot water temperatures. The temperature of the mixed water is detected by the temperature sensor 17, and fed back to the electric flow control valve 6c by the signal converter 18 and control panel 19 to control the valve opening and adjust the temperature of the circulating water. It is supposed to be done.

Electronic feedback control as shown in FIGS. 2 and 3 has the following advantages. Since the shower water temperature is always electrically controlled and is maintained at the set temperature using a feedback control method, even if the temperature and pressure of circulating water or high-temperature water fluctuates, the response is quick and the water temperature is accurately stabilized, making it safe. It is also excellent in sex. Since it is an electrically controlled system, the degree of freedom in control can be increased by combining other electrical parts, solenoid valves, pumps, etc., making it possible to create injection patterns according to the user's preferences.

Next, an example shown in FIG. tlS4 will be described. Water heater 1
The piping to which high temperature water is sent is thermomixing valve 6.
It is connected to the piping that sends cold water from the water supply device 2 and the circulating hot water storage W! A pipe for sending circulating water from 5 is connected to a three-way valve 21 as a directional control valve E, and the three-way valve 21 and the thermomixing valve 6a are connected by the pipe. At the time of initial water supply, switch the three-way valve 21 to the water supply device 2 side (the fourth
flow in the direction of arrow A). Then, the high temperature water and cold water are supplied to the thermomixing valve 6a and adjusted to an appropriate temperature, and clean water adjusted to an appropriate temperature r14 is injected from the body injection nozzle 4. When hot water is stored in the circulating hot water tank 5 to a preset water level using a water level detector or the like, the three-way valve 21 is switched to the circulating hot water tank 5 side (so that the water flows in the direction of the arrow in Figure 4), and the circulating water is thermomixed. The three-way valve 21 is connected to the water supply device 2 when clean water is used as hot water to be sent to the valve 6a for economical recycling operation as in the previous embodiment.
Switch to gA. Note that the three-way valve 2 serves as the directional control valve E.
1 may be not only an electric three-way valve for direction switching control but also a combination of two electric two-way valves for automatic switching. The embodiment of FIG. 4 has the following advantages. Thermomixing valve 6a as external valve D with temperature control function W14
A low-cost system can be constructed because the spray nozzle, piping components, etc. can be used for both clean water and circulating water. initial lit
There is no need for waiting time until the circulating water is prepared in the circulating hot water storage WI5, and it is convenient to take a bath immediately. The body injection nozzle 4 is cleaned each time to pass clean water into the initial water and the rising hot water, so that there is less accumulation of dirty water in the piping, the trouble of maintenance and exploration can be saved, and the period until maintenance and exploration can be extended.

Next, the embodiment shown in FIGS. 5 and 6 will be described. Generally speaking, the mixing of city water managed by water bureaus with miscellaneous trees once released into water supplies through pipes or mixer taps is called a cross-connection, and is not desirable from a health and safety standpoint.

This is because when the city water becomes depressurized due to a water outage, etc., miscellaneous water may flow back into the city water side and contaminate the clean water1.
In this embodiment, the thermo-mixing valve 6a and the three-way valve 21
This prevents the city water from mixing with other trees even if the water is connected to the water. In the embodiment shown in FIG. 5, the configuration is as follows. A check valve 22 is provided in the hot water pipe gA9 of the thermomixing valve 6a to prevent the backflow of sewage in the circulating water, and at the same time, the vacuum breaker 23 sucks out atmospheric air to prevent contamination of city water. There is.

° A check valve 2 is installed on the circulating water side of the thermo-mixing valve 6a.
2 and an air vent 24 are provided, so that when the circulation pump 8 is stopped, the liquid level drops to the water level of the circulation storage mm15 and a continuous layer of air is formed. Circulating savings i
When the drain valve 13 of the tank 5 is opened, the water in the piping up to the thermomixing valve 68 can be automatically drained, and even if the city water side becomes depressurized, the water can be circulated and stored. The check valve 22 and the vacuum breaker 23 prevent the sewage on the 5 side from being sucked.
is configured as shown in FIG. 7, for example. Check valve 22
It has a disk 26, a valve seat 27, an id 28, etc. Vacuum breaker 23 has a spring 29 and a ball 30
．． It has O-rings 31, 32, 33, etc. Check valve 2
2 prevents backflow due to negative pressure action that occurs when tap water pressure drops abnormally or when water is cut off, and when water is flowing, the disc 26 floats to open the tap. - When negative pressure is generated on the next side, the disc 26 of the check valve 22 closes, and at the same time, the ball 30 of the vacuum breaker 23 compresses the spring 29, opening the valve and sucking the atmosphere to create a vacuum state. Shut off to prevent trouble. Normally, it is pushed up by a spring 29 and kept closed by an O-ring. Further, since the air bleed 24 has the functions of both air bleed and vacuum breaker, a commercially available automatic air bleed and valve is used.

The embodiment shown in FIG. 6 has a structure using a three-way valve 21, similar to the embodiment shown in FIG. thermo mixing valve 6g
A check valve 22a and a vacuum breaker 2 are installed on the hot water piping side 9.
3a, and a check valve 22b and a vacuum breaker 2 are provided between the thermomixing valve 6a and the three-way valve 21.
3b, and a check valve 22c and a vacuum breaker 23c are provided on the cold water piping side of the three-way valve 21. In the case of a clean water circuit (flow in the direction of the arrow in Figure 6) Check valve 22a
, 22C and vacuum breakers 23a, 23c can prevent backflow of sewage, and in the case of a circulating water circuit (flow in two directions with arrows in tIS6), backflow can be prevented by check valves 22a, 22b and vacuum breakers 23g, 23b.

The embodiments shown in FIG. tt45 and FIG. 6 have the following advantages. The check valve 22 and the vacuum breaker 23 can double prevent circulating water directly connected to clean water (city water) from flowing back toward the clean water side, resulting in extremely high safety and hygiene. Piping materials and temperature p! jThermomixing valve 6ay as valve D with EPI4 function>tlpl Since it can be used for both water purification and circulating water, the piping space can be reduced and construction can be simplified. In addition, piping members can be saved, and the total cost can be significantly reduced.

The water in the circulation pump 8 and filter 11 is automatically drained at the same time as the water in the circulation hot water storage tank 5 is drained, so there is no accumulation of sewage, less bacterial growth and dirt film formation, and less maintenance and inspection. It takes less time.

[Effects of the Invention] The present invention is configured as described above, and since it is a circulating type in which circulating water is circulated to create a shower, even if a large amount of hot water is injected from a plurality of injection nozzles, compared to a discharge type. This results in significant fuel savings and water savings, resulting in a significant reduction in running costs.Moreover, even though a large amount of hot water is being supplied, high-temperature water obtained via a heating device such as a water heater is mixed by adjusting the temperature of a valve. A valve with a 5-g temperature adjustment function is connected, and this temperature-adjusted circulating water is injected from the body injection nozzle, so the water temperature is highly stable and accurate.
It improves the comfort of bathing, and even lowers the temperature of hot water! Because water is mixed and heated using a valve with a regulating function, the system is simple, low cost, and easy to maintain, compared to using a dedicated water heater or complicated waste heat recovery equipment for reheating.
