[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sanitary washing device that ejects washing water from a jet outlet to wash a human body part, and more particularly to a sanitary washing device capable of controlling a physical quantity representing the state of washing water.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a sanitary washing device that jets washing water to wash a human body part is known. In many of such sanitary washing apparatuses, various physical quantities representing the state of washing water can be controlled in order to perform comfortable washing. Examples of such physical quantities include the temperature of washing water and the water flow of washing water.
[0003]
On the other hand, a sanitary washing apparatus has conventionally been proposed that has a butt washing mode for washing the vicinity of the anus and a bidet washing mode for washing a female local area. In this way, even in a sanitary washing apparatus having two washing modes, various physical quantities representing the state of washing water can be controlled. It is also known that women's local area controls the physical quantity of washing water in consideration of sensitivity.
[0004]
For example, in the bidet cleaning mode, a sanitary cleaning device has been proposed in which the temperature of the cleaning water is controlled to be lower than that in the butt cleaning mode (for example, a sanitary cleaning device described in Japanese Patent Publication No. 3-7767 and JP-A-60-40443). ). In the sanitary washing device described in Japanese Patent Publication No. 3-7767, the temperature of the washing water is controlled to be lower than that in the buttocks washing mode by lowering the heater voltage in the bidet washing mode. In the sanitary washing device described in Japanese Patent Application Laid-Open No. 60-40443, by preparing a tank that stores washing water for the butt washing mode and a tank that stores washing water for the bidet washing mode at a temperature lower than that, The temperature of the cleaning water in the bidet cleaning mode is lowered.
[0005]
As for the washing water flow, it is known that the area of the jet outlet in the bidet washing mode is larger than the area of the jet outlet in the butt washing mode. By doing so, the flow rate of the washing water is slower in the bidet washing mode than in the buttocks washing mode, and a soft washing feeling can be obtained.
[0006]
[Problems to be solved by the invention]
However, since women's local areas are very sensitive, there is a demand in the bidet cleaning mode that the physical quantity should be adjusted more appropriately than the butt cleaning mode. On the other hand, in the buttocks cleaning mode, there is a demand for making it possible to adjust the physical quantity widely in order to obtain a feeling of cleaning according to preference. Although the conventional sanitary washing device controls the physical quantity of washing water to be different in both washing modes, it has not been able to sufficiently meet such requirements. For example, in the sanitary washing apparatus with temperature control described above, the temperature in the bidet washing mode is always controlled to be lower than the temperature in the buttocks washing mode. In order to obtain a desired feeling of washing in the buttocks washing mode, when the temperature of the washing water was set to be relatively low, even lower temperature washing water was ejected in the bidet washing mode. Women's local areas are so sensitive that they sometimes feel a strong discomfort due to the low temperature wash water being ejected.
[0007]
The present invention has been made to solve the above-mentioned problems, and in a sanitary washing apparatus capable of controlling the physical quantity of washing water, the sanitary washing apparatus capable of more appropriately adjusting the physical quantity of washing water in each washing mode The purpose is to provide.
[0008]
[Means for solving the problems and their functions and effects]
In order to solve at least a part of this problem, the present invention has the following configuration.
The present invention of Sanitary washing equipment
A sanitary washing device for washing human body parts by ejecting washing water supplied from the outside through a jet nozzle,
A washing mode designating means for designating a butt washing mode in which washing water is jetted to the anus and a bidet washing mode in which washing water is jetted to a female local area;
First setting means for setting a physical quantity representing the state of the cleaning water in the buttocks cleaning mode;
A second setting means capable of setting the physical quantity representing the state of the cleaning water in the bidet cleaning mode independently of the physical quantity set by the first setting means;
The gist is provided with a cleaning means for controlling the state of the cleaning water to a state corresponding to the designated mode and executing the cleaning.
[0009]
According to such a sanitary washing device, the physical quantity of washing water can be set independently in the butt washing mode and the bidet washing mode. By making it possible to set the two without correlation, the physical quantity can be set so that an appropriate cleaning feeling can be obtained according to each cleaning mode.
[0012]
In addition, as said physical quantity, various physical quantities can be mentioned. For example, the water flow and temperature of washing water can be mentioned. In a sanitary washing apparatus that uses washing water mixed with bubbles, the amount of bubbles mixed in or the diameter of the bubbles may be used as the physical quantity.
[0014]
The present invention of In sanitary washing equipment,
It is desirable that the first setting means and the second setting means can set the physical quantity in each cleaning mode regardless of the cleaning mode being executed by the cleaning means.
[0015]
By doing so, for example, the physical quantity of the cleaning water in the bidet cleaning mode can be adjusted even during operation in the buttocks cleaning mode. Therefore, after setting the physical quantity of cleaning water in the bidet cleaning mode to an appropriate value, switching from the butt cleaning mode to the bidet cleaning mode can be executed, and uncomfortable feeling at the time of switching can be avoided. Of course, the same effect can be obtained when switching from the bidet cleaning mode to the buttocks cleaning mode.
[0020]
The present invention of In sanitary washing equipment,
At least when switching from the hip cleaning mode to the bidet cleaning mode is instructed, a switching control unit is provided for switching the cleaning mode after the state of the sprayed cleaning water reaches a state corresponding to the bidet cleaning mode. It is desirable to make it.
[0021]
In general, there is a delay in switching the state of washing water to be ejected. According to the above configuration, since the switching is performed after the state of the cleaning water reaches the state corresponding to the bidet cleaning mode in consideration of the delay, it is possible to avoid feeling uncomfortable at the beginning of the bidet cleaning mode. it can. Since female locals are very sensitive, comfortable cleaning can be realized by executing the control at least when switching from buttocks cleaning to bidet cleaning. Of course, when switching from the bidet cleaning mode to the buttocks cleaning mode, it is needless to say that switching should be executed after the state of the cleaning water reaches a state corresponding to the buttocks cleaning mode. Note that `` the state corresponding to the bidet cleaning mode has been reached '' does not mean only when it corresponds exactly to the corresponding state, but means that the state has reached a range where no discomfort is felt. Yes.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
(1) Device configuration:
Next, embodiments of the present invention will be described based on examples. FIG. 1 is an explanatory diagram showing a schematic configuration inside a sanitary washing apparatus 10 as an embodiment of the present invention. The sanitary washing device 10 is attached to the toilet main body 14, and is a device that ejects water supplied from a general water pipe to a local part of the human body to wash the local body part.
[0025]
The sanitary washing device 10 is assembled in a casing 16 fixed to the toilet body 14. The water absorption pipe 12 is formed so as to be connectable to a water pipe, and serves as a supply path of cleaning water from the water pipe to the sanitary washing device 10. The sanitary washing device 10 is connected to the pump 20, the suction head 30, the heat exchanger 40, the flow rate adjustment valve 50, and the nozzle 70 in this order from the water absorption pipe 12 side. The cleaning water supplied from the water absorption pipe 12 passes through each component of the sanitary cleaning device 10 in this order, and is then ejected from the nozzle 70. In addition, each component can be arranged in various orders from upstream in addition to the order described above.
[0026]
The pump 20 adjusts the washing water supplied from the water absorption pipe 12 to a pressure suitable for washing. The pump 20 also adjusts the flow rate of the cleaning water by adjusting the pressure of the cleaning water. By turning on the pump 20, the cleaning water is ejected from the nozzle 70. The pressure of the washing water can be adjusted by the user as will be described later.
[0027]
The suction head 30 is a part that performs the function of mixing bubbles in the cleaning water. In the present embodiment, air can be mixed into the cleaning water at a predetermined rate by sending in air pressurized by the air pump 32 connected to the suction head 30. The principle of mixing bubbles will be described with reference to FIG. FIG. 2 is an enlarged view of a cross section of the suction head 30. The washing water flows from the left side to the right side in the figure. The suction head 30 has a configuration in which an air chamber 35 is provided inside a housing 34 and a cylindrical bubble dispersion 36 is fixed. The diameter of the flow path through which the washing water flows is about 1.5 to 3.0 mm. The housing 34 is provided with an air introduction pipe 37 for sending air pressurized by the air pump 32 into the air chamber 35.
[0028]
The bubble dispersion 36 is formed of a porous body having a large number of openings. The pores formed in the porous body are fine pores such that water does not leak to the outside at about the pressure of the washing water passing through the inside, and air can be sent from the outside to the inside due to a pressure difference between the inside and outside.
[0029]
The cell dispersion 36 is formed by heat-molding substantially spherical particles of ultrahigh molecular weight polyethylene. When the substantially spherical particles are heat-molded, independent openings in which the voids are divided by the particles can be formed on the surface of the cell dispersion 36. In order to fill the substantially uniform particles, the apertures are almost regularly arranged in a lattice shape. The regularly arranged openings have an advantage that the generated bubbles can be prevented from being united. Since the particles are fused by thermoforming, there is also an advantage that they are excellent in strength against water pressure and air pressure.
[0030]
Ultra high molecular weight polyethylene has the advantage that the surface properties can be easily controlled during molding by sufficiently controlling the heating temperature and melting it at a temperature slightly above the melting point of the resin. In addition, there is an advantage that it has physical properties suitable for application to a part of the flow path of the washing water, such as being chemically stable and having almost no water absorption.
[0031]
The average particle diameter of the particles is 50 μm to 300 μm. However, if the particle diameter of the material is controlled, the pores can be controlled, so the bubble diameter of the generated bubbles is determined by the average particle diameter of the material. When an average particle diameter of 50 μm to 300 μm is used, pores that obtain a bubble diameter of 100 μm to 1000 μm are formed. To increase the bubble diameter, the particle diameter of the material should be increased. To decrease the bubble diameter, the particle diameter of the material should be decreased.
[0032]
The bubble dispersion 36 can be formed of other various materials. For example, a substantially spherical particle of acrylic resin or a fiber material such as nylon knitted in a substantially lattice shape may be used. Further, metals such as bronze and stainless steel, glass, and the like can also be used. In addition to using the heat-meltable powder, a material in which continuous pores are formed using phase-shifting glass, a ceramic material, or the like may be used.
[0033]
When the air pressurized by the air pump 32 is sent from the air introduction pipe 37 to the air chamber 35, the air is sent from the opening of the bubble dispersion body 36 into the pipe and swells at each opening. When the air swells to a predetermined size, it is cut off by the shearing force received from the washing water flowing in the pipe and becomes bubbles, and is mixed into the washing water. In this example, the diameter of the independent opening of the bubble dispersion 36 was set so that the diameter of the formed bubbles was about 100 to 1000 μm. The air pump 32 only needs to be capable of steady operation with a pumping capacity of about 50,000 to 100,000 Pa, and various types such as a rolling pump, a vane pump, a rotary pump, and a linear pump can be employed.
[0034]
The heat exchanger 40 is a so-called instantaneous water heater. The cleaning water is directly heated by the heater 42 and supplied to the nozzle 70. In this embodiment, a ceramic heater is used as the heater 42. The heat exchanger 40 has the capability of heating the wash water to about 40 degrees Celsius according to the user setting.
[0035]
FIG. 3 is an explanatory diagram showing the internal structure of the heat exchanger 40. 3 is a cross-sectional view from the side of the heat exchanger 40, and the right side of FIG. 3 is a cross-sectional view from the front. The heat exchanger 40 is formed by a heater 42 supported by a plurality of separators 46 inside a housing 44. The washing water flows on both sides of the heater 42 as shown on the left side of FIG. The separators 46 are arranged in a staggered manner as shown on the right side of FIG. The washing water is branched by the separator 46 and flows with stirring. The separator 46 improves the heat transfer efficiency from the heater 42 to the cleaning water due to such an effect.
[0036]
The structure of the nozzle 70 will be described. FIG. 4 is a cross-sectional view showing the internal structure of the nozzle 70. Two cleaning water passages having a circular cross section are formed inside the nozzle 70. The small-diameter channel is a buttocks cleaning water channel 72 that serves as a cleaning water channel for buttocks cleaning. The large-diameter dew is a bidet washing water channel 74 that serves as a washing water channel for bidet washing. In this embodiment, the diameter of the buttocks cleaning water channel 72 is about 1.9 mm, and the diameter of the bidet cleaning water channel 74 is about 2.5 mm. In addition, both the flow paths are about 95 mm, and the pressure loss in the buttocks cleaning water channel 72 and the pressure loss in the bidet cleaning water channel 74 are set to be substantially equal. The bottom cleaning channel 72 has a smaller diameter and a larger pressure loss per unit length, so the channel length is slightly shorter than the bidet cleaning channel 74. At the tip of the nozzle 70, there are provided a butt cleaning water jet 73 connected to the butt cleaning water channel 72 and a bidet cleaning water jet 75 connected to the bidet cleaning water channel 74. The buttocks washing water spout 73 has one spout. The bidet washing water spout 75 has two large and small spouts, and the washing water is ejected simultaneously from both spouts.
[0037]
In the present embodiment, the diameters of the buttocks cleaning water channel 72 and the bidet cleaning water channel 74 are changed in order to obtain different cleaning feelings. In this embodiment, the diameter of the buttocks cleaning water channel 72 is smaller than the diameter of the bidet cleaning water channel 74. Accordingly, the flow rate of the cleaning water in the butt cleaning water channel 72 is faster than the flow rate of the cleaning water in the bidet cleaning water channel 74. The time from when the bubbles are mixed into the washing water until it is ejected is shorter for the butt washing than for the bidet washing. In general, it is known that the bubble diameter increases in correlation with the elapsed time after mixing. Therefore, in this embodiment, the washing water used for butt washing is more than the washing water used for bidet washing. Bubble diameter is reduced. The smaller the bubble diameter, the harder the cleaning feeling. As described above, the difference between the bubble diameter and the jetting speed makes the ass cleaning different from the bidet cleaning. In this example, the ass cleaning gives a harder cleaning feeling than the bidet cleaning. Can do.
[0038]
A switching mechanism for switching the supply destination of the cleaning water to the buttocks cleaning water channel 72 and the bidet cleaning water channel 74 is provided at the root of the nozzle 70. In addition, a nozzle drive motor 60 for driving the nozzle 70 forward and backward is provided. The nozzle drive motor 60 advances the nozzle 70 from the standby position of the casing 16 to the buttocks cleaning position or further to the bidet cleaning position in front of it, or retracts from both cleaning positions to the standby position. Each movement is shown by broken lines in FIG.
[0039]
The switching mechanism switches the supply destination of the cleaning water in conjunction with the movement of the nozzle 70. FIG. 5 is an explanatory diagram showing a mechanism for switching the supply destination of cleaning water and its function. As shown in the drawing, the switching mechanism includes a support body 76 that is slidably supported by the nozzle body 71 via a spring 78, and a shielding block 79 that is fixed to the casing 16. The support 76 is formed with a flow path 77 through which the washing water that has passed through the heat exchanger 40 flows. When the nozzle 70 is in the standby position (the position indicated by the broken line in FIG. 5A), the shielding block 79 and the support 76 do not interfere with each other. Even when the nozzle 70 moves from the left to the right in FIG. 5A and reaches the buttocks cleaning position, the shielding block 79 and the support 76 do not interfere with each other. In these states, the support body 76 is positioned above by receiving the biasing force of the spring 78, and the flow path 77 of the support body 76 and the buttocks cleaning water channel 72 face each other. Accordingly, the cleaning water passes through the buttocks cleaning water channel 72 in the nozzle 70 and is ejected from the buttocks cleaning water outlet 73.
[0040]
When the nozzle 70 is advanced to the bidet cleaning position, the support 76 comes into contact with the shielding block 79. As a result, as shown in FIG. 5B, the support 76 is pushed downward by the shielding block 79, and the flow path 77 of the support 76 and the bidet washing water channel 74 face each other. Accordingly, the washing water passes through the bidet washing water channel 74 in the nozzle 70 and is ejected from the bidet washing water outlet 75. When the nozzle 70 is returned from the bidet cleaning position to the standby position, the support 76 is returned to the upper initial position by the biasing force of the spring 78.
[0041]
Each of the above operations is controlled by the control device 100 shown in FIG. The control device 100 is a microcomputer having a CPU, RAM, and ROM therein, and controls the operation of each component of the sanitary washing device 10 according to various control programs stored in the ROM. Various sensors are connected to the control device 100 in order to perform this control. For example, a seating sensor 102 for detecting that the user is seated, a temperature sensor 106 for detecting the temperature of the cleaning water, and a light receiving unit 104 for inputting an infrared signal from the remote controller 200 can be cited. The seating sensor 102 of this embodiment detects the electrostatic capacity of a heater provided for heating the toilet seat, and detects the seating based on the change between when the seat is seated and when it is not. In addition, various sensors such as a sensor that detects a pressure acting between the toilet body 14 and the toilet seat at the time of sitting can be applied as the seating sensor 102.
[0042]
The remote controller 200 is a device that converts a user's intention into an infrared signal and outputs the infrared signal. An outline of the remote controller 200 is shown in FIG. As shown in the figure, the remote controller 200 is provided with a button group for commanding an operation, an operation unit for setting the operation, and an operation on / off button 202 for turning on / off the entire sanitary washing apparatus. ing. The buttons for instructing the operation include a butt cleaning button 206 for starting local cleaning, a bidet cleaning button 208, a drying button 210 for starting hot air blowing, a stop button 204, and a butt cleaning. The massage setting button 212 for setting the ejection of washing water with a change in the strength of the water inside, the massage setting button 214 for setting the ejection of washing water with the strength change during the bidet washing, and the nozzle 70 are shaken. There is a move setting button 216 for setting the moved local cleaning. The operation unit for setting the operation includes ass washing water temperature setting buttons 224H and 224L for adjusting the temperature of the washing water at the time of ass washing, ass washing water setting buttons 226H and 226L for setting the strength of the water, and a bidet. Bidet cleaning water temperature setting buttons 225H and 225L for adjusting the temperature of the cleaning water at the time of cleaning, bidet cleaning water power setting buttons 227H and 227L for setting the strength of the water force, a nozzle position adjusting button 228F for adjusting the position of the nozzle 70 in the front-rear direction, 228B, a deodorizing button 218 for setting the deodorizing state, a toilet seat temperature adjusting knob 220 for setting the toilet seat temperature, and an indoor heating button 222 for setting on / off of the indoor heating. The operation results and setting results of these buttons are displayed on the display unit 230 by a lamp or liquid crystal.
[0043]
In this embodiment, the temperature and water flow of the cleaning water can be set independently in the butt cleaning mode and the bidet cleaning mode. The display unit 230 displays a set value corresponding to the operated mode. For example, when the butt cleaning water temperature setting buttons 224H and 224L are operated, the temperature indicator of the display unit 230 displays the temperature of the cleaning water in the butt cleaning mode. When the bidet cleaning water temperature setting buttons 225H and 225L are operated, the temperature indicator of the display unit 230 displays the temperature of the cleaning water in the bidet cleaning mode.
[0044]
The state of control by the control device 100 will be described with an example of a normal cleaning sequence. FIG. 7 is a time chart showing a sequence when the buttocks are washed. When the seating sensor detects that the user is seated on the toilet seat (time t1), the control device 100 starts the air pump 32 to perform the remaining water treatment. By sending air into the nozzle 70, the washing water remaining in the nozzle 70 is driven out. At this point, the nozzle 70 is stored in the casing 16.
[0045]
When the user operates the hip cleaning button 206 of the remote controller 200 (time t2), the control device 100 detects this signal by the light receiving unit 104 and starts pre-cleaning. That is, the pump 20 and the air pump 32 are driven, and washing water is ejected from the nozzle 70 at a predetermined pressure. The pre-cleaning is a process for cleaning dirt, bacteria, and the like attached to the inside of the nozzle 70 and the tip. At this point, the nozzle 70 is still stored in the casing 16. When the pre-cleaning for a predetermined time is completed (time t3), the control device 100 temporarily stops driving the pump 20 and the air pump 32. Then, the nozzle drive motor 60 is controlled to advance the nozzle 70 to a predetermined butt cleaning position. During this time, the flow rate adjusting valve 50 is once returned to the origin, and the opening degree is set according to the water pressure set by the water pressure setting buttons 226H and 226L of the remote controller 200.
[0046]
When the nozzle 70 comes to the buttocks cleaning position (time t4), the control device 100 drives the pump 20 and the air pump 32 to perform the main cleaning. Washing water in which bubbles are mixed at a predetermined ratio is ejected from the buttocks washing water outlet 73 of the nozzle 70 to wash the buttocks. During this time, the control device 100 controls the current of the heater 42 according to parameters such as the flow rate of the cleaning water so as to keep the temperature of the cleaning water at a temperature set by the user. When the user operates the move setting button 216, the control device 100 controls the nozzle drive motor 60 in response to the movement of the nozzle. When the user operates the stop button 204 to instruct the end of cleaning (time t5), the control device 100 stops driving the pump 20 and the air pump 32. Thereafter, the nozzle drive motor 60 is controlled to retract the nozzle 70 to the standby position. During this time, the flow rate adjusting valve 50 is once returned to the origin and then set to the fully open position again.
[0047]
When the nozzle 70 returns to the standby position in the casing 16 (time t6), the control device 100 starts post-cleaning. The pump 20 and the air pump 32 are driven, and washing water mixed with bubbles at a predetermined ratio is ejected from the nozzle 70. The post-cleaning is cleaning for removing dirt attached to the nozzle 70 by the main cleaning. When the predetermined time has elapsed, the control device 100 stops driving the pump 20 and the air pump 32 and ends the post-cleaning. Thereafter, when the seating sensor 102 detects that the user has left the toilet seat (time t7), the control device 100 drives the air pump 32 to send air into the nozzle 70. Thereby, the washing water remaining in the nozzle 70 is discharged. The reason for discharging the washing water is to avoid the propagation of various germs and the corrosion of the apparatus. Moreover, it is also for avoiding that cleaning water enters into the independent opening of the bubble dispersion 36. Depending on the user's instructions, there may be a case where after the main cleaning is completed, an operation of blowing hot air to dry the local portion is included.
[0048]
(2) Cleaning mode control:
Next, cleaning mode control in the sanitary cleaning device 10 of the present embodiment will be described. FIG. 8 is a flowchart showing the cleaning mode control process. This process is a process repeatedly executed by the CPU in the control device 100 together with other control processes.
[0049]
When the cleaning mode control routine is started, the CPU inputs the currently executed cleaning mode (step S10). As described above with reference to FIG. 5, the CPU executes control of the switching mechanism of the nozzle 70 in accordance with the cleaning mode. Therefore, the current cleaning mode can be easily identified in the cleaning mode control routine of FIG. Next, the CPU inputs designation of the cleaning mode (step S20). The cleaning mode is designated by the user operating the hip cleaning button 206 and the bidet cleaning button 208 of the remote controller 200. The CPU detects the designation of the cleaning mode by inputting a signal corresponding to this operation through the light receiving unit 104.
[0050]
The CPU determines whether the input cleaning mode is the buttocks cleaning instead of the current cleaning mode (step S30). If it is the buttocks cleaning mode, the cleaning water temperature and water pressure corresponding to the buttocks cleaning mode are input next (step S40). Subsequently, if the current cleaning mode is the bidet cleaning mode, it is determined that the mode should be switched (step S50). If the mode should be switched, the switching mechanism shown in FIG. 5 is controlled to switch the cleaning mode (step S60). After switching the washing mode in this way, the heater heating control is executed to control the washing water temperature to the designated temperature (step S120). Of course, the pump 20 and the suction head 30 are also controlled at the same time to control the water flow to a designated state.
[0051]
On the other hand, when the input cleaning mode is not the buttocks cleaning but the bidet cleaning (step S30), the cleaning water temperature set value Tb and the water flow corresponding to the bidet cleaning mode are input (step S70). Subsequently, when the current cleaning mode is the buttocks cleaning mode, it is determined that the mode switching is instructed (step S80). When the mode switching instruction is given, the CPU detects the temperature T of the cleaning water (step S90). The temperature of the cleaning water is detected by the temperature sensor 106. Next, it is determined whether or not this temperature substantially matches the set value Tb (step S100). That is, it is determined whether or not the absolute value of the deviation between the set value Tb and the cleaning water temperature T is smaller than the predetermined value α. When the deviation is in a range smaller than α, the switching mechanism shown in FIG. 5 is controlled to switch the cleaning mode (step S110). If this deviation is greater than or equal to α, switching of the cleaning mode is skipped. Thereafter, the heating control of the heater is executed to control the cleaning water temperature to the designated temperature (step S120). Of course, the pump 20 and the suction head 30 are also controlled at the same time to control the water flow to a designated state.
[0052]
As described above, the cleaning mode control routine is a repeatedly executed process. Therefore, when switching from the butt cleaning mode to the bidet cleaning mode is instructed, even if the cleaning mode switching process (step S110) is skipped, the switching is performed after a predetermined time has elapsed. This is because when the heater heating control (step S120) is executed, the temperature T of the cleaning water gradually approaches the set value Tb corresponding to the bidet cleaning mode, and the deviation between the two becomes smaller than α.
[0053]
In this embodiment, when switching from the butt cleaning mode to the bidet cleaning mode, the switching is executed after waiting for the temperature of the cleaning water to sufficiently converge to the set value. There is usually a delay in the temperature change of the wash water. If switching to the bidet cleaning is executed immediately after the switching of the cleaning mode is instructed, there is a possibility that the cleaning water at the temperature set in the buttocks cleaning mode is jetted immediately after the switching. The female locals are sensitive and may feel a strong discomfort when the washing water at such temperature is spouted out. In this embodiment, such discomfort is avoided by waiting for the temperature of the cleaning water to sufficiently converge to the set value.
[0054]
In this embodiment, when switching from the bidet cleaning mode to the buttocks cleaning mode, the switching is executed without waiting for the temperature of the cleaning water to converge to the set value corresponding to the buttocks cleaning mode (step S50, (See S60). In this embodiment, if the user waits for the set value, the washing water ejection temperature changes to the set value in the bidet cleaning mode. Considering that the female local area is sensitive, in the bidet cleaning mode, it is desirable to avoid the temperature of the cleaning water from changing to a value other than the set value Tb. In this embodiment, when switching to the buttocks cleaning mode from this point of view, the switching is executed without waiting for the temperature of the cleaning water to converge. Of course, at the time of switching to the buttocks cleaning mode, the nozzle 70 may be temporarily retracted to the standby position, and after waiting for the temperature of the cleaning water to converge, control to advance to the buttocks cleaning position again may be performed. .
[0055]
As described above, the sanitary washing device 10 according to the present embodiment has a cleaning water temperature (referred to as the butt cleaning temperature) and water (referred to as the butt cleaning water) in the butt cleaning mode, and cleaning in the bidet cleaning mode. The water temperature (referred to as bidet washing temperature) and the water flow (referred to as bidet washing water flow) can be set independently. FIG. 9 shows the relationship between the buttocks washing water temperature and the bidet washing water temperature. As shown in the drawing, the butt washing water temperature can be set in the range of 20 to 40 ° C. The bidet washing water temperature can be set in the range of 25 to 38 degrees. In this embodiment, the bidet cleaning water temperature setting range is set to be narrower than the buttocks cleaning water temperature setting range, and the bidet cleaning water temperature setting range is included in the buttocks cleaning water temperature setting range. ing.
[0056]
By suppressing the maximum value of the bidet cleaning water temperature to be lower than the maximum value of the buttocks cleaning water temperature (see region H in FIG. 9), the cleaning water temperature is prevented from becoming too hot for female locals. Similarly, by making the minimum value of the bidet cleaning water temperature higher than the minimum value of the buttocks cleaning water temperature (see region L in FIG. 9), the cleaning water temperature is prevented from becoming too cold for the female local area. In this way, a comfortable washing feeling can be obtained for the female locals. On the other hand, by widening the range of changes in the buttocks cleaning water temperature, it is easy to obtain a feeling of cleaning according to preference in the buttocks cleaning mode.

According to the sanitary washing device 10 of the present embodiment described above, since the temperature and the water flow of the washing water can be set independently in both the buttocks washing mode and the bidet washing mode, comfortable washing is realized respectively. be able to. In some cases, the bidet washing water temperature is lower than the buttocks washing water temperature, a comfortable washing feeling can be obtained in each washing mode, and conversely, the bidet washing water temperature is preferably higher than the buttocks washing water temperature. For example, in the summer season, it is more comfortable to wash the buttocks with a relatively low temperature washing water, but the bidet washing may be uncomfortable if the temperature is not slightly warm. According to the sanitary washing apparatus 10 of the present embodiment, the water temperature and the water force in both washing modes can be set independently, so the degree of freedom is high in the setting, and a comfortable washing feeling is more appropriate in each washing mode. Obtainable. In addition, the sanitary washing device 10 according to the present embodiment can also eliminate discomfort during switching by executing switching to bidet cleaning after the temperature of the cleaning water has sufficiently converged. In the above-described embodiment, the water temperature and the water flow can be set independently in the buttocks cleaning mode and the bidet cleaning mode. However, other physical quantities such as the amount of bubbles mixed in and the bubble diameter can be set independently. You can also.

By sliding the slide bars 224b and 225b to the left and right, the cleaning water temperature in each cleaning mode can be set. The movable parts of the slide bars 224b and 225b correspond to the temperature ranges that can be ejected in the respective cleaning modes. By using such a display unit, the set value of the cleaning water temperature in each cleaning mode can be confirmed at a glance. In addition, since the indicator and the operation unit are combined, there is an advantage that the operability is excellent.
[0062]
FIG. 12 shows an example of an interface having a common operation unit in the buttocks cleaning mode and the bidet cleaning mode. The temperature can be adjusted by rotating the adjustment knob 224c shown in the drawing to the left and right. FIG. 12B is a side view of the adjustment knob 224c. As illustrated, the adjustment knob 224c can be operated in a normal state P1 and a depressed state P2. If the adjustment knob 224c is operated in the normal state P1, the buttocks washing water temperature can be set. If the adjustment knob 224c is operated in the depressed state P2, the bidet washing water temperature can be set. The set temperature is displayed on a separate display. By using such an operation unit, it is possible to independently set the water temperatures of both cleaning modes while avoiding an increase in the size of the remote controller 200.
[0063]
(3) Second embodiment:
Next, a sanitary washing device as a second embodiment of the present invention will be described. The hardware configuration of the sanitary washing device as the second embodiment is the same as that of the sanitary washing device 10 (see FIG. 1) as the first embodiment. The second embodiment is different from the first embodiment in the method of setting the temperature and water flow of the cleaning water in the buttocks cleaning mode and the bidet cleaning mode.
[0064]
In the second embodiment, the washing water temperature and the water flow in both modes are set with correlation. An example of the correlation related to the washing water temperature is shown in FIG. FIG. 13 is a graph showing the cleaning water temperature in each cleaning mode with respect to the operation amount of the temperature setting operation unit. The straight line L1 gives the cleaning water temperature in the buttocks cleaning mode, and the straight line L2 gives the cleaning water temperature in the bidet cleaning mode. As shown in the figure, the width of the change in the cleaning water temperature in the bidet cleaning mode is smaller than that in the buttocks cleaning mode. The minimum temperature (corresponding to the operation amount of 0%) in each cleaning mode is higher in the bidet cleaning mode than in the buttocks cleaning mode. The maximum temperature (corresponding to an operation amount of 100%) is lower in the bidet cleaning mode than in the buttocks cleaning mode. In the present embodiment, the relationship between the operation amount and the temperature is set so that the bidet washing water temperature is included in the butt washing water temperature. Actually, such correlation is tabulated and stored in the ROM in the control device 100.
[0065]
In the sanitary washing apparatus of the present embodiment, by operating one operation unit, the temperatures of both the butt washing mode and the bidet washing mode are set simultaneously based on the correlation shown in FIG. For example, when the operation amount is 50%, the buttocks cleaning water temperature is set to 30 ° C., and the bidet cleaning water temperature is set to 32 ° C. A table that gives the relationship between the operation unit and the water flow is prepared separately and stored in the ROM in the same format as shown in FIG.
[0066]
The cleaning mode control by the control device 100 is substantially the same as the control process (FIG. 8) described in the first embodiment. In the first embodiment, the cleaning water temperature and the water flow are input independently for each cleaning mode (steps S40 and S70). On the other hand, in the second embodiment, the CPU inputs the operation amount (%) of the temperature setting operation unit, and by referring to the table shown in FIG. 13 according to the designated cleaning mode, the cleaning water temperature and Set the water force.
[0067]
According to the sanitary washing device of the second embodiment, since the state of the washing water in both washing modes can be set with one operation unit, there is an advantage that the operability is excellent. The correlation of FIG. 13 is made by making the width of the bidet cleaning water temperature smaller than the width of the buttocks cleaning water temperature and making the minimum temperature of the bidet cleaning water higher than the minimum temperature of the buttocks cleaning water temperature with respect to the operation amount. By setting the relationship, it is possible to avoid feeling uncomfortable especially during bidet washing. The same applies to water. In addition, it is possible to easily obtain a feeling of cleaning according to the user's preference by making it possible to set the temperature and the water flow in a wide range during the buttocks cleaning. As a result, comfortable cleaning can be realized in both cleaning modes.
[0068]
In the above embodiment, the water temperature and the water flow have been described as examples. However, other physical quantities such as the amount of bubbles mixed in and the diameter of bubbles can also be controlled based on the same table as in FIG. FIG. 13 shows a case where the change in the washing water temperature according to the operation amount is set linearly. On the other hand, at least one of them may be set non-linearly.
[0069]
Although various embodiments of the present invention have been described above, the present invention can be carried out in various modes without departing from the spirit of the present invention. For example, in this embodiment, the sanitary cleaning apparatus using cleaning water mixed with bubbles has been described as an example, but it goes without saying that the present invention can also be used for a sanitary cleaning apparatus of a type that does not mix bubbles in cleaning water. In the present embodiment, an example using the instantaneous heat exchanger 40 is shown, but a hot water storage type heat exchanger may be used.
