After that, the water flow is stopped, and then the control valve is controlled so that both the first and second flow paths are in communication with the washing water heating means again with the start of the local washing operation. And passing water for a predetermined time while heating the cleaning water by the cleaning water heating means. A controller is provided.
With this configuration , Both the first and second flow paths communicating with the water discharge hole , Preheat when approaching the human body, and again with the start of the local cleaning operation By preheating, particularly when the flow path is extremely cold during extremely cold weather, the distribution ratio of the wash water to the first and second flow paths is determined by the distribution ratio setting means according to the user's preference. No matter what the ratio is set, it is possible to wash at a comfortable hot water temperature from the start of water discharge. In other words, from the start of cleaning, it is possible to clean comfortably with an appropriate hot water temperature and a user's preferred cleaning feeling.
[0006]
In the human body washing apparatus according to the second aspect of the invention, the washing water heating means is an instantaneous heating means capable of continuously raising the temperature of the washing water only when necessary.
By using an instantaneous heating means, the washing water is not heated when the device is not in use, so significant power savings can be achieved. In addition, washing water that has cooled in the heating means when not in use can be discharged, and the inside of the washing water channel can be preheated.
[0007]
In the human body cleaning device according to a third aspect of the invention, the second flow path is a diffusion flow path for diffusing the wash water and discharging it from the water discharge hole, and the first flow path is more linear than the diffusion flow path.

As a result, it is possible to increase the temperature raising capability of the washing water and reduce the output of the heating means, contributing to water saving and power saving, and a significant energy saving as a whole. In addition, since the flow rate can be reduced, the flow volume of the wash water can be kept low, and hence the heat capacity of the wash water flow path can be reduced, and the wash water flow path can be preheated in a shorter time. Is possible.
[0010]

[0012]
In FIG. 1, a pressure regulating valve 12, a solenoid valve 13, and a heat exchanger 14 are connected in order from the upstream side to a water supply pipe 11 that supplies cleaning water. A vacuum breaker 15 is connected to the outlet of the heat exchanger 14. The downstream of the vacuum breaker 15 branches in two directions, one being connected to a drain pipe 16 for discharging excess water directly into the toilet and the other connected to a pulsation generator 17. A flow path switching / flow rate adjusting valve 18 is connected downstream of the pulsation generator 17. The downstream of the flow path switching / flow rate adjusting valve 18 branches in two directions, one connected to the drainage channel 19 and the other connected to the nozzle device 21 that ejects the wash water to the human body via the flow path switching / flow rate control valve 20. It has been done. In this example, the flow path switching / flow rate control valve 20 is configured integrally with the nozzle device 21.

In addition, the nozzle device 21 includes three types of first and second flow paths 25 and 26 for butt cleaning that communicate with the buttocks cleaning water discharge hole 63 and a bidet flow path 27 that communicates with a bidet cleaning water discharge hole (not shown). A flow path is constructed. The control of each part is performed by the controller 28.
[0014]
In this embodiment, an accumulator 29 is provided upstream of the pulsation generator 17, and a float switch 30 is provided in the heat exchanger 14. The accumulator 29 is for preventing the pulsation generated by the pulsation generator 17 from propagating upstream, and the float switch 30 does not energize the hot water heater 22 when a predetermined water level is not detected. By doing so, it is to prevent airing.
[0015]
With the above configuration, the wash water supplied from the water supply pipe 11 by the opening operation of the electromagnetic valve 13 is heated to an appropriate temperature by the heat exchanger 14, pushes up the vacuum breaker 15, and is pulsated by the pulsation generator 17. To the flow path switching / flow control valve 18. Here, the flow rate of the washing water is adjusted by the flow path switching / flow rate adjusting valve 18 and reaches the flow path switching / flow rate ratio control valve 20, and the flow path selected by the flow path switching / flow rate ratio control valve 20 has a predetermined flow rate. It flows in at a ratio and is ejected from the nozzle device 21.
[0016]
Next, FIG. 3 shows a schematic perspective view schematically showing the internal structure of the nozzle head 61 representing the buttocks washing channel structure in the first embodiment of the present invention. In this figure, the bidet washing channel is omitted.
As shown in the drawing, the nozzle head 61 is located at the outside air entraining chamber 62, the buttocks cleaning orifice 65, the throat 67, and the end of the throat. A passage 64 is provided, and a washing water vortex chamber 66 is provided below the buttocks washing orifice 65. The cleaning water supply path includes a first flow path 25 connected to the cleaning water vortex chamber 66 with its axis oriented, and a second flow path 26 connected eccentrically to the vortex chamber. The two flow paths are distributed to a predetermined ratio (Qa, Qb) determined by the flow switching / flow rate control valve 20 based on the water flow and the washing area selected by the user with the remote control switch. Wash water flows in.
[0017]
FIG. 4 shows an example of a disk shape for switching the flow path and controlling the flow ratio by the flow path switching / flow rate ratio control valve 20. In this control valve, the flow rate of the cleaning water is determined in which flow path and at what ratio by the overlapping shape of the hole shape of the rotor 81 that is the movable disk and the hole shape of the stator 84 that is the fixed disk. ing.
[0018]
The rotor 81 is provided with through holes 82 and 83, and the stator 84 has a through hole 87 that communicates with the bidet flow path 27, an opening 85 that communicates with the first flow path 25, and the second flow path 26. And an opening 86 communicating therewith. In addition to the through holes 85a and 86a communicating with the first and second flow paths 25 and 26, the two openings 85 and 86 have a flow rate for finely controlling the ratio of the washing water flowing through the two flow paths. The groove adjusting portions 85b and 86b are provided.
[0019]
Here, examples of the combination angle of the rotor 81 and the stator 84 are shown in FIGS. In these drawings, the communicating portion is indicated by hatching by the combination of the rotor 81 and the stator 84. 4A shows a state where only the first flow path 25 is communicated, FIG. 4B shows a state where only the second flow path is communicated, and FIG. 4C shows only a state where the bidet flow path 27 is communicated. The state, Fig. 4 (g), shows the state of communication with all the flow paths (state during self-cleaning described later).
[0020]
If it is desired to adjust to the relationship of Qa >> Qb, the rotor 81 and the stator 84 are adjusted so that the state shown in FIG. Further, when it is desired to finely adjust the ratio of Qa and Qb, for example, when Qa is to be increased by changing the overlapping degree of the through hole 82 and the flow adjusting groove 86b, the rotor 81 is to be decreased clockwise. Can be finely adjusted by appropriately rotating the rotor 81 counterclockwise.
[0021]
Similarly, when it is desired to adjust the relationship of Qb >> Qa, the rotor 81 is brought into the state shown in FIG. 4D, and when Qa and Qb are adjusted to substantially the same ratio, the rotor 81 is brought into the state shown in FIG. You can adjust the angle of.
[0022]
From here, the state of water discharge when the cleaning water is discharged from the nozzle head 61 will be described.
First, when cleaning water is supplied only to the first flow path 25, the cleaning water flows into the cleaning water vortex chamber 66 with its axis directed. The cleaning water that has flowed in in this manner passes through the orifice 65 with little swirling in the vortex chamber, and is discharged from the buttocks cleaning water discharge hole 63 with little interference with the throat 67. In this case, since the swirl does not occur in the washing water in the vortex chamber, the following water discharge situation occurs.
[0023]
(1) Since the amount of air entrained in the outside air entraining chamber 62 is smaller than when the cleaning water is swirled, the soft feeling is reduced.
(2) The form of water discharge is not cone-shaped KS, but remains almost cylindrical. For this reason, as shown in FIG. 3, a narrow cleaning area SMa can be intensively and strongly cleaned with cylindrical cleaning water with a small amount of air mixing. The above phenomenon occurs even when the flow rate ratio Q1 of the first flow path 25 and the flow rate ratio Q2 of the second flow path 26 are Q1 >> Q2.
[0024]
On the other hand, when the flow rate ratios Q1 and Q2 are adjusted in the relationship of Q2 >> Q1, the wash water supplied from the second flow path 26 dominates the behavior of the vortex chamber, and thus flows into the vortex chamber from both paths. The washing water swirls in the vortex chamber as shown by the arrow SY in the figure.
[0025]
Therefore, (1) this water discharge increases the amount of air entrained in the outside air entraining chamber 62, and the water can be discharged with a sufficiently soft feeling. (2) Since the water discharge form is a cone-shaped KS, as shown in FIG. 3, a large cleaning area SMc can be cleaned while giving a feeling of sufficient amount of water due to a large amount of air mixing.
[0026]
When the flow rate switching / flow rate control valve 20 is adjusted so that the flow rate ratios Q1 and Q2 are substantially the same, the influence of the washing water from the second flow channel 26 on the behavior of the vortex chamber is reduced. come. Therefore, when the flow rate ratio is adjusted in this way, the washing water flowing into the vortex chamber from both flow paths swirls in the vortex chamber as indicated by the arrow SY in the figure, but the degree of swirl is reduced, and the following It becomes like this.
(1) The amount of air entrained in the outside air entraining chamber 62 decreases as the degree of swirl becomes smaller, so the soft feeling becomes water discharge that gradually fades away.
(2) Although the water discharge form is a cone-shaped KS, depending on the degree of swirling, the washing area is narrow and is about SMb as shown in FIG. 3, and water discharge at a flow rate ratio Q1 >> Q2 and Q2 >> Q1 The feeling of washing is intermediate to that of water discharge.
[0027]
Therefore, according to this nozzle head 61, the amount of air mixing, the water discharge strength, the washing area and the soft feeling were variously adjusted by the simultaneous water supply from both the flow paths and the flow rate ratio adjustment of each flow path at that time. Wash water can be discharged.
As described above, since the cleaning feeling can be adjusted as described above, the nozzle head 61 can be configured as follows.
[0028]
When the buttocks cleaning switch 43 is selected, the flow rate switching / flow rate control valve is controlled so that the flow rate ratio Q1: Q2 becomes Q1 >> Q2 in order to perform strong cleaning, and the soft cleaning switch 44 is selected. In this case, in order to gently wash a wide area, the flow rate ratio Q1: Q2 is controlled so that the flow rate ratio Q1: Q2 becomes Q2 >> Q1, and the cleaning water is discharged.
[0029]
Further, when the cleaning area selection switch 47a of the remote controller 41 is pressed in order to perform cleaning in the user's preferred cleaning range, the flow path is switched so that the ratio of Q2 is increased with respect to the flow rate ratio Q1: Q2 in order to increase the cleaning area. When the cum / flow ratio control valve 20 is controlled and the washing area selection switch 47b is pressed, the flow switching / flow ratio control valve 20 is controlled to increase the ratio of Q1 in order to reduce the washing area. Is also possible.
The flow rate ratio can be adjusted as follows by operating the water flow control switches 46a and 46b.
[0030]
When the water flow adjustment switch 46a is pressed, the flow path switching / flow rate control valve 20 is controlled to increase the flow rate ratio Q1 in order to wash more powerfully and firmly, and when the water flow adjustment switch 46b is pressed, a softer In order to clean gently with a feeling of cleaning, the flow path switching / flow rate control valve 20 is controlled so as to increase the flow rate ratio Q2.
[0031]
As described above, according to the nozzle head 61 in the present embodiment, it is possible to adjust the width of the cleaning area and the soft feeling with a single water discharge hole, which can meet the user's demand for a fine feeling of cleaning. A nozzle can be realized.
[0032]
Next, Fig. 5 shows the time chart of the present invention. When the seating sensor (not shown) provided in the human body cleaning device detects the seating of the user, the electromagnetic valve 13 is opened to start the cleaning water flow, and the hot water heater 22 in the heat exchanger 14 is activated. Do it. Thereby, when the hot water thermistor 24 provided in the water discharge part in the heat exchanger 14 detects a predetermined temperature, the output of the hot water heater 22 is lowered, the electromagnetic valve 13 is closed, and the flow of the washing water is stopped. Thereby, the stagnant water in the heat exchanger 14 is replaced with hot water of a predetermined temperature.
[0033]
Here, the flow path switching / flow rate adjusting valve 18 is switched from the draining position to the flow path toward the nozzle device 21 side, and the downstream flow path switching / flow rate control valve 20 is previously set in the self-cleaning (SC) position. Therefore, the cleaning water is discharged from the water discharge hole of the nozzle device 21. That is, the cleaning water flow path from the heat exchanger to the buttocks cleaning water discharge hole 63 and the bidet cleaning water discharge hole (not shown) is preheated. Note that the self-cleaning position mentioned here indicates a state in which all three flow paths of the first and second flow paths 25 and 26 and the bidet flow path 27 for the buttocks cleaning are opened.
[0034]
These series of operations are controlled by the controller 28. In addition to the hot water thermistor 24 provided in the water discharge portion of the heat exchanger 14, a cold water thermistor 23 is provided in the water intake portion of the heat exchanger 14 to detect the incoming water temperature. By doing so, the control of the hot water heater 22 can be performed more effectively. (Water heating)
As described above, the output of the hot water heater 22 is lowered after the flow of the wash water is stopped. At this time, the temperature of the wash water stored in the heat exchanger 14 is always within a predetermined temperature range including the predetermined temperature. The output of the hot water heater 22 is controlled by the controller 28 based on the signal from the hot water thermistor 24 so as to be maintained.
[0035]
For example, when the predetermined temperature is set to 40 ° C. and the predetermined temperature body is set to 38 to 42 ° C., the temperature of the washing water in the heat exchanger 14 is controlled to always fall within this range. This heat retention control eliminates the worry of unpleasantness due to low temperature water being discharged when washing the human body, and hot water coming out and causing burns. (Insulation control)
[0036]
Next, when the buttocks switch 43 is operated to start the buttocks cleaning, the solenoid valve 13 and the hot water heater 22 are activated. These activations are performed in conjunction with the operation of the buttocks switch 43. Of course, after the operation of the buttocks switch 43, each can be set to be activated after a predetermined time delay.
[0037]
Here again, the flow path switching / flow rate adjusting valve 18 is switched from the draining position to the flow path toward the nozzle device 21 side, and the downstream flow path switching / flow rate ratio control valve 20 is previously in the self-cleaning (SC) position. Therefore, the cleaning water is discharged from the water discharge hole of the nozzle device 21. The washing water flow path from the heat exchanger to the bidet washing spout is preheated again. In this case, since cleaning water is discharged from all the water discharge holes provided in the nozzle device 21, a cleaning effect in the vicinity of the water discharge holes can also be obtained. (Pre-cleaning)
[0038]
After the pre-cleaning is performed for a predetermined time, the flow path switching / flow rate adjusting valve 18 switches the flow path of the cleaning water to the drainage path 19, and the nozzle device 21 extends to the buttocks cleaning position. Since the drainage destination of the drainage channel 19 is at a position where the body of the nozzle device 21 can be washed, the body of the nozzle device 21 can be washed. (Nozzle extension)
[0039]
When the extension of the nozzle to the butt washing position is completed, the flow path switching / flow rate control valve 20 is switched to a predetermined position designated by the switch of the remote controller 41, and the flow path switching / flow rate adjustment valve 18 is cleaned. The water flow path is switched from the drainage path 19 to the nozzle device 21 side, and the flow rate is driven to gradually rise toward the set water flow. Even if the set water force is strong, the setting water force gradually changes from soft water discharge, so that the user is not uncomfortable. (Soft start)
[0040]
The above is an example of the soft start by the flow path switching / flow rate adjusting valve 18, but can also be implemented by using the pulsation generator 17. For example, at the start of cleaning, a high-frequency pulsation that provides a soft cleaning feeling is applied to the cleaning water, and the frequency is gradually decreased, or the output to the pulsation generator 17 is gradually increased, so that the same flow rate is obtained. However, the cleaning strength can be gradually increased. Of course, in order to continuously increase the cleaning strength, both the flow path switching / flow rate adjusting valve 18 and the pulsation generator 17 may be controlled in a complex manner.
At the same time, the output of the pulsation generator 17 is controlled so as to gradually increase toward the set water force.
[0041]
When the soft start operation is completed, since the warm water heater 22 and the flow path of the washing water are all sufficiently preheated, no matter what the flow ratio Q1: Q2 is selected by the user, The soup is washed comfortably at the set hot water temperature. Here, since the pulsation is given to the washing water by the function of the pulsation generator 17, the washing can be performed comfortably even with a small amount of water. (Main wash)
[0042]
Next, when the stop switch 42 is operated in order to stop the buttocks cleaning, the pulsation generator 17 stops driving, and the flow path switching and flow rate adjusting valve 18 switches the flow path of the cleaning water to the waste water path 19. The nozzle device 21 is stored up to the standby position. At this time, the body of the nozzle device 21 can be cleaned as in the case of nozzle extension. The flow path switching / flow rate control valve 20 is switched to the self-cleaning position. (Nozzle storage)
[0043]
When the storage of the nozzle is completed, the flow path of the washing water is switched again to the nozzle device 21 side by the flow path switching / flow rate adjusting valve 18 and the pulsation generator 17 is also started. Here, the flow path switching / flow rate control valve 20 is set to the self-cleaning position, and the cleaning water is discharged from all the water discharge holes of the nozzle device 21. In other words, post-cleaning is performed in and around the water discharge hole. At this time, since the post-cleaning is performed with the pulsating cleaning water, the water discharge hole and the dirt in the vicinity can be washed off effectively. (Post-cleaning)
[0044]
During a series of operations from the pre-cleaning to the post-cleaning described above, the controller 28 keeps the wash water flowing out of the heat exchanger 14 at an appropriate temperature based on signals from the hot water thermistor 24 and the cold water thermistor 23. It is controlled as follows.
[0045]
After the post-cleaning is performed for a predetermined time, the pulsation generator 17 and the electromagnetic valve 13 stop driving in order, and the hot water heater 22 decreases the output. Also here, the temperature control is performed so that the temperature of the washing water stored in the heat exchanger 14 is always kept within a predetermined temperature range including the predetermined temperature. This is to prevent discharge of low-temperature water or hot water even when cleaning is performed again. (Insulation control)
[0046]
When the seating sensor (not shown) detects separation (seating off), the hot water heater 22 stops driving. However, in order to prevent freezing of the washing water in the heat exchanger 14, when the cold water thermistor 23 or the hot water thermistor 24 detects a water temperature that may freeze, the hot water heater 22 is driven for a predetermined time to supply the washing water. Perform warming control. (Standby)
[0047]
In the present embodiment, the description has been made on the buttocks and the soft washing, but it is needless to say that the present invention can be applied to the bidet washing.
In this embodiment, a seating sensor is used as a means for detecting the use of the device. However, an open / close detection sensor for detecting the opening / closing of the toilet lid, a human body detection sensor for detecting the proximity of the human body to the device, and the like. It can also be applied.
[0048]
In the present embodiment, the human body cleaning apparatus using the instantaneous heating type heat exchanger has been described. However, even if the human body cleaning apparatus using the hot water storage type heat exchanger is applied, It is possible to obtain various cleaning effects.
[0049]
Furthermore, although the above-mentioned example explained the human body cleaning apparatus that performs local cleaning especially in the human body, it goes without saying that this embodiment can be applied to general human body cleaning apparatuses such as showers and faucets.
