Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a technology for controlling jet water of a shower device.

[Background Art] In general, showers have 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 momentum to proactively utilize the thermal effects of skin stimulation in addition to the cleansing effects of showering and bathing. The thermal effect of a shower generally dilates skin blood vessels and increases blood flow, promoting substance metabolism, relieving muscle stiffness, recovering from fatigue, and relieving mental and physical tension. Are known. 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 shower bathing, blood vessels will repeat expansion and contraction as appropriate, activating various functions of the autonomic nervous system. It can also be expected to have beauty effects. However, in order to activate the blood flow to internal organs and muscles by changing the temperature of the hot water, and to actively exert the aerobic effect that relieves lack of exercise and stress, and the beauty effect of skin stimulation, it is necessary to change the temperature of the hot water. Management needs to be done appropriately.

Conventional hot and cold water injection devices use city water as low-temperature water, so the water temperature fluctuates greatly depending on the season. For example, in the case of city water in Osaka, the temperature is 5 to 6 degrees Celsius in the winter.
There was a difference of more than 20 degrees Celsius from 27 to 28 degrees Celsius in summer, and the drawback was that it was too cold to use, especially in winter, when the city's water temperature was low.

In addition, from the experimental results of the inventor of the present invention, the following conditions were confirmed as conditions for a comfortable hot and cold water injection device.

(a) In the case of alternate injection of hot and cold water, the constant temperature of hot water of 38 to 40℃ and cold water of about 10℃ lower than body temperature is repeated without causing discomfort.

(b) The desirable ratio of hot water and cold water injection times is about 10 seconds of hot water and 2 to 3 seconds of cold water; if the cold water time is too long, the body will not feel warm, and if it is too short, the stimulating effect of the hot and cold water will be reduced.

(c) It is desirable to be able to fine-tune the cold water temperature and time settings in accordance with seasonal changes in outside temperature and the individual's physical condition and preferences.

[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 provide a shower device that can spray hot and cold water in a manner that is comfortable for the human body and enhances physiological effects. be.

[Disclosure of the invention] First, an embodiment of a circulating shower device that controls the temperature of hot water using a thermomixing valve shown in FIG. 1 will be described. The shower device main body 1 has a size that allows a person to stand up and take a shower, and a circulating water tank 2 is provided at the bottom of the shower device main body 1, and the water that falls from the shower device main body 1 is used for circulating water. It is designed to accumulate in tank 2. A hot and cold water injection nozzle 3 and a hot water only injection nozzle 4 are provided in the shower device main body 1. The shower device main body 1 includes a first supply pipe line 21 and a second supply pipe line 2.
2, one end of the first supply pipe 21 is connected to the first
It communicates with the hot and cold water injection nozzle 3 via a solenoid valve 8, and one end of the second supply pipe 22 communicates with the hot and cold water injection nozzle 3 via a second electromagnetic valve 9. A first mixing valve 6 is provided at the other end of the first supply conduit 21, and a second mixing valve 7 is provided at the other end of the second supply conduit 22.
The first mixing valve 6 is connected to a high-temperature water supply path 23 that supplies high-temperature water from the water heater 5, and a low-temperature water supply route 2 that supplies low-temperature city water.
4 are connected. The second mixing valve 7 is communicated with a high-temperature water supply path 23 that supplies high-temperature water from the water heater 5, and also with a low-temperature water supply route 25 that supplies low-temperature water from the circulating water tank 2. A filter 1 is installed in the low temperature water supply path 25.
1 and a pressure pump 12 are interposed. A branch pipe 26 is branched from the second supply pipe 22, and this branch pipe 26 is communicated with the hot water injection nozzle 4. The first solenoid valve 8 and the second solenoid valve 9 are controlled by a controller 10.

First, low-temperature water, which is city water, flows through the low-temperature water supply route 24.
The high-temperature water that is supplied to the first mixing valve 6 from
3 to the first mixing valve 6,
The hot water is mixed to a preset temperature with the first mixing valve 6, and when the first electromagnetic valve 8, which is an on-off valve controlled by the controller 10, is opened, the water is jetted out from the hot and cold water injection nozzle 3, and used as circulating water. Stored in tank 2. When the circulating water tank 2 becomes full, the first electromagnetic valve 8 closes, and the jetting from the hot and cold water jet nozzle 3 stops. This is the preparation stage. In the case of hot water injection when showering or bathing,
The hot water stored in the circulating water tank 2 is passed through the filter 1
1. After passing through the pressure pump 12, the high temperature water from the high temperature water supply path 23 is mixed in the second mixing valve 7 to compensate for the temperature drop due to heat radiation, and the hot water adjusted to the required temperature is transferred to the second supply pipe. 22. The hot water supplied to the second supply pipe 22 is spouted from the hot and cold water injection nozzle 3 by opening the second solenoid valve 9 as an on-off valve, and the hot water is ejected from the branch pipe 2.
The hot water is ejected from the hot water injection nozzle 4 via the hot water injection nozzle 4.
On the other hand, in the case of alternate hot and cold water injection, circulating water tank 2
The hot water is heated by the second mixing valve 7 as injection hot water, and the hot water is supplied to the second supply pipe 22, and the first mixing valve 6 mixes low temperature water and high temperature water to generate the above hot water. Cold water adjusted to a certain lower temperature is supplied to the first supply pipe 21, and hot water from the second supply pipe 22 and cold water from the first supply pipe 21 are alternately injected. In other words,
The controller 10 alternately opens and closes the first solenoid valve 8 and the second solenoid valve 9, thereby controlling the hot and cold water to be alternately injected. Here, the hot water injection nozzle 4 is used exclusively for hot water injection to alleviate shock to the heart. Further, the additional amount of water supplied from the city water is discharged from the overflow pipe 13, which has the effect of preventing excessive contamination of the circulating water. The water used in the circulating water tank 2 after bathing is finally discharged from the drain valve 14. The injection pattern of hot and cold water can be controlled by the controller 10, and the setting of the temperature of the cold water can be easily adjusted by manually adjusting the first mixing valve 6.

Next, the embodiment shown in FIG. 2 will be described. In the case of this embodiment, an example is shown in which an electric three-way valve is used to switch water channels in a discharge type shower device. One ends of the first supply pipe line 21 and the second supply pipe line 22 are communicated with the hot and cold water injection nozzle 3 via an electric three-way valve 17 as an on-off valve. The first mixing valve 6 and the second mixing valve 7 are connected to a high-temperature water supply path 23 that supplies high-temperature water from a hot water source 18 and a low-temperature water supply pathway 24 that supplies low-temperature water from a water source 19. Therefore, the second mixing valve 7 adjusts the temperature so that hot water with a high temperature is obtained and supplies the hot water to the second supply pipe 22, and the first mixing valve 6 obtains cold water with a certain temperature lower than the above-mentioned hot water. Hot water is supplied to the first supply pipe line 21 with its temperature adjusted so that the temperature is adjusted so that the temperature of the water is adjusted so that the hot water is supplied from the second supply pipe line 22, and cold water is supplied from the first supply line 21 through the electric three-way valve 17. The water is alternately sprayed from the hot and cold water spray nozzles 3. That is, hot and cold water is alternately injected by alternately switching the hot water and cold water circuits of the electric three-way valve 17 controlled by the controller 10. When the electric three-way valve 17 is used in this manner, the piping section of the valve is simplified, which is advantageous in terms of workability, cost, and reliability.

In the embodiments shown in FIGS. 1 and 2, thermomixing valves that automatically adjust the temperature using diaphragm type thermowax elements are used for the first mixing valve 6 and the second mixing valve 7, but instead It is cheaper and easier to use a mixing valve that allows you to manually adjust the water temperature to your preference. In addition, by using an electric control valve that detects the mixed water temperature with a temperature sensor and provides feedback control of the valve opening on the high-temperature water side and the low-temperature water side, the injection time and water temperature of hot and cold water can be easily adjusted. Program control is also possible to maximize the bathing effect.

[Effects of the device] As mentioned above, this device sprays hot and cold water alternately, so the activation of blood flow is remarkable. In this case, the skin temperature peaks and decreases within 30 minutes after showering, but in the case of alternating hot and cold water injections, the skin temperature continues to rise even after 30 minutes have passed.
Activation of blood flow is significant). Generally, two bathtubs are required to perform a hot and cold water bath, which is not easy due to the installation space and equipment cost.However, with this invention, hot and cold water is sprayed alternately, so it takes up less space for a shower device and can be used at a lower cost. effect can be obtained. Moreover, since the present invention sprays hot and cold water alternately, the cold water activates skin cells by tightening the skin, has a beauty effect, and prevents the bath from feeling cold, compared to a shower spray of only hot water. Furthermore, since hot and cold water is sprayed alternately, blood flow increases in a short time, reducing bathing time, saving water and energy, and reducing running costs. Furthermore, two systems of pipelines, a first supply pipeline and a second supply pipeline, are provided in the main body of the shower device, and a first mixing valve for mixing high-temperature water and low-temperature water is provided in the first supply pipeline, and a high-temperature water A second mixing valve for mixing water and low-temperature water is provided in the second supply pipe, and a high-temperature water supply route and a low-temperature water supply route are communicated with the first mixing valve and the second mixing valve, respectively, and the high-temperature water supply route and the low-temperature water supply route are connected to the first mixing valve and the second mixing valve, respectively. The provided injection nozzle was communicated with the first supply pipe and the second supply pipe through an on-off valve such as a solenoid valve or an electric three-way valve.
Mixing high-temperature water and low-temperature water with a mixing valve or a second mixing valve to supply hot water adjusted to an appropriate temperature to one of the first supply pipe or second supply pipe, and cold water adjusted to an appropriate temperature to the other. It can supply hot water and cold water from the injection nozzle, and can freely adjust the temperature of hot and cold water to spray, so that the temperature of city water changes depending on the season or the air temperature changes depending on the season. The temperature of hot or cold water can be adjusted and sprayed according to the user's physical condition, preferences, and physiological effects, and the hot and cold water can be sprayed in a way that is comfortable for the human body and enhances physiological effects. Moreover, the injection nozzle provided in the main body of the shower device is communicated with the first supply pipe and the second supply pipe through an on-off valve such as a solenoid valve or an electric three-way valve, and the first supply is made from the injection nozzle. In order to alternately inject the supply water from the pipeline and the supply water from the second supply pipeline, we installed a control device that is set to open and close the on-off valve alternately, so hot water and cold water are alternately injected. The shower time can be freely changed, and the time for spraying hot water and the time for spraying cold water can be changed according to the conditions of use, so that the shower can be made comfortable and enhance physiological effects.
