されており、便秘解消策が要望されている。2. Description of the Related Art It is generally said that about one third of the Japanese population is constipated, and women and the elderly in particular tend to have constipation. This is because in females, progestin, a female hormone, acts to suppress peristaltic movements of the large intestine, and in elderly people, the muscles and nerves of the body are weakened and the activity of the large intestine is weakened. On the other hand, when constipation occurs, the function of the autonomic nervous system decreases and metabolism deteriorates, unpleasant symptoms such as impaired blood circulation and rough skin, increased breakouts occur, and in recent years, colorectal cancer due to constipation, It has been reported that the disease develops into diseases such as colonic polyps and intestinal stenosis, and a measure for eliminating constipation is demanded.

In recent years, when a warm water flush toilet seat equipped with a sanitary flushing device that cleans the anus with warm water causes constipation. It has been known that there is. This is considered to be due to stimulation of the anus by warm water washing to induce anal reflex.

子型の洗浄ノズルが構成されている。FIG. 15 shows the configuration of such a conventional sanitary washing apparatus, and FIG. 16 shows a sectional view of the washing nozzle. In FIG. 1, reference numeral 1 denotes a cleaning nozzle having an ejection hole 2 and reference numeral 3 denotes a hot water tank for heating and storing cleaning water, and has a heater 4. 5 is a water pump for supplying washing water, and 6 is a water stop solenoid valve. The cleaning nozzle 1 is provided in adhering walls 8 and 9 provided on both sides of the orifice 2 and a pair of vortex chambers 10 and 11 provided on both sides of the jet flow direction. It has suction pores 12 and 13 and constitutes a fluid oscillation element type cleaning nozzle.

ととなる。In this configuration, when the cleaning water from the hot water tank 3 flows into the cleaning nozzle 1, the flow velocity is increased by passing through the throttle portion 7, and the cleaning water adheres to the adhesion wall 8 side by the Coanda effect (fluid adhesion effect). Then, it gushes in the direction of arrow A. At this time, the washing water flows into the vortex chamber 10, and the vortex is generated, so that the air is sucked from the intake pores 12 and the pressure in the vortex chamber 10 increases. This pressure acts to move the water flow to the adhering wall 9 side, and the jet flow moves to the arrow B side. By repeating this state, a self-oscillation state is established, and the washing is performed while the jet flow swings.

調感を低減することが可能となる。The operation and operation of this embodiment in the above configuration will be described. When the washing switch 23 is turned on, the water stop electromagnetic valve 14 is opened, and the washing water heated and stored in the hot water tank 15 flows into the washing nozzle 18 through the opening / closing valve 20, and flows from the ejection hole 19 to the anus. Spouted toward, and cleaning is started. On the other hand, when the intermittent drive switch 25 is selectively turned on after the washing switch 23 is turned on, the intermittent drive circuit 22 operates to control the valve opening of the on-off valve 20, and as shown in FIG. 2 (a) or (b). The washing water amount is controlled to increase or decrease at a predetermined cycle fv. Here, it is said that the anal canal of the human body performs peristalsis at a predetermined rhythm cycle, the number of times is about 15 times / min, and the cycle fh is about 4 seconds. Therefore, the increasing / decreasing cycle fv of the washing water amount is set to the natural number n (1.2 ·
..), That is, fh / n, that is, 4 seconds, 2 seconds, 1.3
It is controlled so as to be substantially synchronized in three seconds. The peristaltic movement of the anal canal becomes more active due to the stimulation of the anus, thereby effectively inducing constipation. In addition, since the rhythm is synchronized with the rhythm based on the human physiology, it is possible to induce bowel movements without causing discomfort. Further, by providing the intermittent drive switch 25, it is possible to select between washing after normal stool use and washing for inducing stool as needed. In addition, since the washing flow rate changes, the washing pressure at the anus changes, and a massage effect can be obtained. Therefore, it is possible to reduce monotonous feeling during washing.

Cleaning water flowing into the cleaning nozzle 18 flows into the nozzle element 1
8a is sprayed toward the human body part, and cleaning is started. When the air mixing switch 42 is not turned on, no air is mixed into the cleaning water, and the cleaning water flowing into the nozzle element 18a is simultaneously jetted from the main jetting hole 44 and the auxiliary nozzle holes 45a and 45b, as shown in FIG. As described above, the respective jets merge and become a strong current which is concentrated and ejected to the human body part. On the other hand, when the air mixing switch 42 is turned on, the air mixing means 39 operates to mix air into the cleaning water through the check valve 44, and the main ejection hole 45 and the auxiliary nozzle hole 45a,
A gas-liquid two-layer flow is ejected from 45b. At this time, the washing water spouted from each spouting hole becomes an irregular intermittent flow because it contains bubbles. In other words, the jet power of the wash water spouted from each jet hole changes in strength, and at the confluence of the two jets, the jet force of the wash jets oscillates over a wide area due to mutual interference due to the jet power of each other. It becomes a soft jet.

選択切り換えできる。This point will be described in detail with reference to the swing principle shown in FIGS. 14 (a) and 14 (b). In the figure, (a) shows a state in which no bubbles are mixed, and (b) shows a state in which bubbles are mixed. Here, the ejection power of the washing water from the main ejection hole 44 is Vm, the ejection power from the auxiliary nozzle holes 45a and 45b is Va and Vb, and the ejection power from the auxiliary nozzle hole 45 is relative to the jet of the main ejection hole 44. Horizontal component Va1,
When Vb1 and the vertical components Va2 and Vb2 are decomposed, when bubbles are not mixed, the forces of the vertical components Va2 and Vb2 are balanced and stabilized, resulting in a concentrated jet as shown in FIG. On the other hand, if air bubbles are mixed in, the washing water ejected from the main ejection holes 44 and the auxiliary nozzle holes 45 becomes an irregular intermittent flow, so that Va2 and Vb2 as shown in FIG.
As a result, the jet flow fluctuates. As described above, the air mixing switch 42 can selectively switch between a concentrated strong jet and a dispersed soft cleaning jet according to the user's preference.
