Description

  The present invention relates to a sanitary washing device for washing a human body.

  A sanitary washing apparatus that hygienically cleans a local part of a human body cleans the washing water by heating it with a warming device, boiling it up to about 40 ° C., and ejecting the warm water from the washing nozzle toward the local area.

  In this type of sanitary washing device, washing is performed by moving the washing nozzle to the vicinity of the local area of the human body and ejecting washing water at the time of washing, so that dirty water tends to adhere to the washing nozzle at the time of washing, and the tip of the nozzle is washed with washing water. Nozzle cleaning is generally performed. Such nozzle cleaning uses cleaning water for local cleaning before or after local body cleaning, and sprays the cleaning nozzle to wash away sewage and filth (see, for example, Patent Document 1).

  However, bacteria and fungi floating in the air are likely to adhere to the surface of the water film after cleaning the nozzle. With the recent increase in airtightness and heat insulation of houses, it has become an environment where these bacteria and fungi can easily grow. It can be considered that the surface of the cleaning nozzle grows after long-term use. These grown bacteria and fungi cannot be sufficiently sterilized by the nozzle cleaning operation at about 40 ° C. as described above, and an improvement in cleanliness is desired.

  For this reason, in recent years, it has been proposed to apply a chemical to nozzle cleaning (see Patent Document 2). FIG. 10 shows the sanitary washing apparatus described in the document 2. In the figure, reference numeral 1 denotes a cleaning nozzle, which has a cleaning cap 3 for performing nozzle cleaning by splashing the cleaning water from the ejection hole 2 at the ejection hole 2 and the position where the cleaning nozzle 1 is stored. A chemical tank 4 is supplied to the chemical supply path 6 by the chemical injection pump 5, and the cleaning water and the chemical liquid 9 that have passed through the original electromagnetic valve 7 and the cleaning water supply path 8 are mixed and flow into the cleaning nozzle 1 and eject The washing nozzle is washed with the chemical liquid by being ejected from the hole 2.

Further, Patent Document 2 discloses that hypochlorous acid generated by electrolyzing water as a chemical solution is applied to nozzle cleaning.

It should be noted that even when the above-mentioned high temperature washing and sterilization is performed in a state where a person is seated on the toilet seat, the position of the hot water discharge port 47 is such that the high temperature hot water (hot water) from the hot water discharge port 47 does not reach the human body. And the direction is determined.

  The butt nozzle 18 and the bidet nozzle 19 are driven by the configuration of the cylindrical piston portion 48, the cylindrical cylinder portion 49, and the spring 50. That is, when the cleaning water is sent to the first outlet channel 36 by the operation of the switching valve 33 shown in FIGS. 3 and 4, the water pressure acts on the cylindrical piston portion 48 and overcomes the force of the spring 50. As shown in FIG. 8, the butt nozzle 18 is pushed out, and hot water is ejected from the discharge port 44.

  When the switching valve 33 is operated by the motor 39 and the first outlet channel 36 is closed, the cylindrical piston portion 48 is pushed back by the force of the spring 50 as shown in FIG. The position of the discharge port 44 can be changed during standby and in use so as to be housed in the main body 12.

The hot water discharge port 47 is configured to cover. As described above, the butt nozzle 18 and the bidet nozzle 19 which are human body washing nozzles are normally housed in the main body 12 of the sanitary washing device, and protrude from the main body of the sanitary washing device when washing the human body. In order to prevent hot water from the hot water discharge port 47 from hitting the human body at the time of germs, high temperature washing is removed except when the buttocks nozzle 18 and the bidet nozzle 19 which are human body washing nozzles are housed in the main body 12 of the sanitary washing device. It is the structure which prohibits the driving | operation operation | movement of a microbe.

  Next, the switching valve 33 will be described in detail with reference to FIGS. 4, 5, and 6. The switching valve 33 includes a housing 51, a valve body 52 that is rotatably inserted into the housing 51, and a motor 39 that rotationally drives the valve body 52. First, the housing 51 includes an inlet channel 35, a first outlet channel 36, a second outlet channel 37, and a third outlet channel 38, and the first outlet channel 36 and the second outlet channel 37 are configured. Are opposed to each other at the cross-section AA, and the third outlet channel 38 is provided at a different cross-sectional position from the two outlet channels as shown in the cross-section BB. Next, the valve body 52 is provided with an internal flow path 53 that is always in communication with the inlet flow path 35 when inserted into the housing 51, and the first valve branches off from the internal flow path 53. A body outlet 54 and a second valve body outlet 55 are configured. The first valve element outlet 54 is positioned corresponding to the first outlet channel 36 and the second outlet channel 37 of the housing 51, and the second valve element outlet 55 is positioned corresponding to the third outlet channel 38 of the housing 51. The degree of communication between the inlet channel 35, the first outlet channel 36, the second outlet channel 37, and the third outlet channel 38 can be varied depending on the rotation angle of the valve body 52. . Note that an O-ring 56 is provided as a seal member to prevent internal leakage or external leakage with respect to each flow path. However, in order to reduce the load on the motor, the X-ring or V-packing is used. It is effective to use a special O-ring. Further, as the motor 39, a stepping motor with a built-in reduction gear that can be accurately positioned by open control is adopted, and the output shaft thereof is attached to the valve body 52. In this embodiment, a stepping motor is used as the motor 39. However, as long as the positioning accuracy can be ensured, a brush-type general-purpose DC motor can be used, and various actuators such as a rotary solenoid can be used. Needless to say. Furthermore, in this embodiment, a rotary flow path switching valve is used, but a linear motion type or diaphragm type, or a disk type valve body that switches multiple flow paths can be easily applied. Is possible.

  In the above configuration, the human body cleaning nozzles 18 and 19 having the discharge ports 44 and 45 for discharging cleaning water for cleaning the human body, and at least the outer surfaces of the discharge ports 44 and 45 of the human body cleaning nozzles 18 and 19 are provided. With the configuration of the sanitary washing apparatus 10 having the high temperature washing and sterilizing means 47 for performing high temperature washing and sterilization, the outer surfaces of the discharge ports 44 and 45 of the human body washing nozzles 18 and 19 are covered by the hot water discharge port 47 which is the high temperature washing and sterilization means. Since it acts so as to sterilize at high temperature, when using the sanitary washing device 10, it can be kept clean by sterilizing at high temperature, so that a person with neatness can use the sanitary washing device with confidence.

The hot water is discharged from the hot water discharge port 47 which is a high temperature cleaning sterilization means when the user presses the sterilization switch 20 of the remote controller 16, the controller 57 incorporated in the sanitary cleaning device 10. The high temperature washing sterilization control means 58 receives the high temperature washing sterilization mode signal and controls the operation of high temperature washing sterilization. That is, when the user presses the sterilization switch 20, the high-temperature washing sterilization control means 58 drives the motor 39 of the switching valve 33 to connect the inlet flow path 35 and the third outlet flow path 38. After the hot water is supplied to the hot water unit 42 and becomes hot water in the hot water unit 42, the outer surfaces of the discharge ports 44 and 45 of the human body cleaning nozzles 18 and 19 are cleaned and disinfected at a high temperature from the hot water discharge port 47. Control to act as follows. As described above, since the high-temperature cleaning / sterilization control means 58 that receives the high-temperature cleaning / sterilization mode signal and controls the operation of the high-temperature cleaning / sterilization is provided, the cleaning water for cleaning the human body can be discharged without troublesome operation. The human body cleaning nozzles 18 and 19 having the discharge ports 44 and 45 and at least the outer surfaces of the discharge ports 44 and 45 of the human body cleaning nozzles 18 and 19 are cleaned and sterilized at a high temperature to cause contamination by fungi and fungi. Can be kept hygienic.

  In the embodiment, the sterilization switch 20 for transmitting the high temperature cleaning sterilization mode signal has been described with the configuration provided in the remote controller 16 of the sanitary cleaning device 10, but the configuration provided in the main body 12 of the sanitary cleaning device 10. Needless to say, it may be. As described above, the sterilization switch 20 for transmitting the high-temperature cleaning sterilization mode signal is provided in the main body 12 of the sanitary cleaning device 10 or the remote controller 16, so that the high-temperature cleaning sterilization can be performed simply and simply by pressing the sterilization switch 20. Can be done.

  Further, the high temperature washing sterilization means 58 is configured to sterilize the human body washing nozzles 18 and 19 using high temperature hot water, so that contamination by fungi and fungi does not occur due to the sterilization action by the high temperature hot water. Can be kept hygienic.

  In addition, the temperature of the hot water which carries out the high temperature washing | cleaning sterilization was 45 degreeC-70 degreeC. In the food field, beverage pasteurization is performed at about 55-60 ° C. On the other hand, when the target was mold and the breeding rate was suppressed, it was considered unnecessary to reach this temperature. Therefore, the results of experiments on Penicillium genus, Cladosporium genus mold and Stachybotrys genus mold isolated from the human body washing nozzle also confirmed the effect of suppressing the reproduction at 45 ° C. In addition, when reducing mold | fungi reliably, it has also confirmed that the hot water of 55 degreeC or more is effective. The higher the temperature, the greater the high temperature sterilization effect, but even if something breaks down, even if hot water is directly sprayed on the human body, it is important to prevent accidental burns from occurring, and the upper limit temperature is The temperature was set to 70 ° C. In this way, the temperature of hot water is set to 45 ° C to 70 ° C, so even if hot water touches the human body, there is no need to worry about instant burns and fungi and fungi effectively. Can be prevented from contamination.

  The high temperature washing sterilization means is provided on the secondary side of the hot water unit and the switching valve in the course of supplying the washing water for washing the human body to the human body washing nozzle and in another branch path that does not communicate with the human body washing nozzle. A hot water unit and a hot water discharge port for discharging hot water from the hot water unit to the outer surface of the discharge port of the human body washing nozzle are provided. With this configuration, the hot water unit is provided in a separate branch path that does not communicate with the human body washing nozzle, so hot water is not discharged from the human body washing nozzle and hits the human body. It can be washed and sterilized. Further, the material constituting the path for supplying the washing water to the human body washing nozzle, the hot water unit in the middle, and the constituting material of the switching valve do not need to be a special heat resistant material.

  Further, at the time of high temperature washing sterilization, the high temperature washing sterilization means 58 controls the flow rate of hot water passing through the hot water unit 42 to a predetermined flow rate. That is, the flow rate is controlled by setting the degree of communication opening between the inlet passage 35 and the third outlet passage 38 of the switching valve 33 to a predetermined amount. The flow signal can be obtained from the flow sensor 30. By controlling the hot water flow rate to a predetermined flow rate, it is possible to prevent the hot water from splashing into the human body, which is safe and secure. In addition, the heat input required to convert the hot water controlled at a constant temperature of, for example, 40 ° C. by the hot water unit 31 into hot water at a constant temperature of, for example, 60 ° C. by the hot water unit 42 is theoretically determined by the flow rate of the hot water. Therefore, the temperature sensor of the hot water unit 42 can be omitted by adopting a configuration in which the flow rate of hot water passing through the hot water unit 42 is controlled to a predetermined flow rate. Moreover, by controlling to a small predetermined flow rate, the amount of heat required for heating by the heater 46 can be reduced, and an energy saving effect can be obtained in combination with the safety described above.

  The heater 46 of the hot water unit 42 is a self-temperature control heater. With this configuration, the electric input is automatically controlled by the self-temperature control heater 46 itself so as to obtain a constant hot water temperature of 60 ° C., for example, without attaching a temperature sensor or the like to the hot water unit 42. For this reason, the hot water unit 42 can be made compact, the temperature of the hot water is almost constant, the sterilization effect can be stabilized, and the user can use it with peace of mind. However, the heater 46 of the hot water unit 42 does not necessarily have to be a self-temperature control heater, and even if it is a general ceramic heater or sheathed heater, the temperature control can be safely performed as long as the temperature control is safe. It goes without saying that there is no problem.

  In addition, the human body washing nozzles 18 and 19 are usually housed in the main body 12 of the sanitary washing device 10 and protrude from the main body 12 of the sanitary washing device 10 when washing the human body. In order to prevent the hot water from the outlet 47 from hitting the human body, the operation of the high temperature cleaning sterilization is prohibited except when the human body washing nozzles 18 and 19 are housed in the main body 12 of the sanitary washing device 10. is there. That is, when the user is washing the human body with the human body washing nozzles 18 and 19, even if the operation button (sanitization switch 20) for instructing the high temperature washing and sterilization of the remote controller 16 is erroneously pressed, the controller 57 does It works so as not to operate the fungus. That is, the signal of the sterilization switch 20 can be received only when the human body washing nozzles 18 and 19 are housed in the main body 12 of the sanitary washing device 10. With this configuration, the user can use the device without worrying about burns.

  Further, a plurality of human body washing nozzles such as a butt nozzle 18 and a bidet nozzle 19 are provided, and at the time of high temperature washing sterilization, the plurality of human body washing nozzles 18 and 19 are simultaneously subjected to high temperature washing sterilization with hot water from the hot water discharge port 47. Even if any human body washing nozzle is used after high temperature washing and sterilization, the human body washing nozzle that has been sterilized at high temperature will be used, and it is sterilized and washed in a clean state with peace of mind. Can do.

  Moreover, the human body washing nozzles 18 and 19 are formed by forming a portion where the temperature of hot water having a high temperature of 45 ° C. to 70 ° C. is made of a heat-resistant material that can sufficiently withstand the high temperature, thereby performing high temperature washing and sterilization. There is no concern about deformation or damage of the human body washing nozzles 18 and 19, and the nozzle can be used safely for a long time.

  In addition, the human body washing nozzles 18 and 19 can sufficiently withstand the high temperature by forming a portion where the temperature of hot water of 45 to 70 ° C. is made of stainless steel, and the cleanliness is also high. The effect of high temperature washing sterilization can be further enhanced.

  Further, the human body washing nozzles 18 and 19 can be resin-molded even if the flow path and the outer shape of the human body washing nozzles 18 and 19 are three-dimensional curved surfaces by making the resin surface covered with metal. By forming a metal film on at least a part of the surface by, for example, plating a metal on the resin surface, it is possible to further enhance the high-temperature cleaning / disinfecting effect on the surface.
