Description

[0001] This application is a divisional application of the invention patent application filed on April 21, 2020, entitled "Sanitary Cleaning Device", with application number "202010315973.X". Technical Field

[0002] The present invention generally relates to a hygienic cleaning device. Background Technology

[0003] Conventionally, methods for preventing the adhesion and accumulation of waste in the toilet bowl have been known to involve spraying water or functional water into the bowl after use. As an example, Patent Document 1 describes a method in which a nozzle for spraying water into the bowl is provided on a personal hygiene cleaning nozzle of a sanitary cleaning device, with the nozzle entering through the housing and spraying water into the bowl from the nozzle outlet. However, in this sanitary cleaning device, the nozzle is configured to enter forward and downward from the shell located on the rear side of the basin. Therefore, when water is sprayed from the spray outlet at a certain spray angle, if the nozzle is allowed to enter, the height of the spray outlet decreases, and the area where the water sprayed from the spray outlet adheres narrows. Consequently, if the nozzle is allowed to spray water from the spray outlet with a larger entry position, it is particularly difficult for water to adhere to the front side of the basin.

[0004] Furthermore, in this sanitary cleaning device, a baffle is provided in front of the nozzle when it is in the retracted state. Therefore, if water is sprayed from the nozzle outlet when it is in the retracted state, although the height position of the nozzle outlet can be ensured, the water will collide with the baffle, making it difficult for water to adhere to the front side of the basin.

[0005] Patent documents Patent Document 1: Japanese Patent Application Publication No. 2015-101942 Summary of the Invention

[0006] The present invention is based on the understanding of such a problem, and the technical problem to be solved is to provide a hygienic washing device in which water can adhere to the front side of the basin from the spray outlet provided in the nozzle.

[0007] The first invention is a hygienic washing device, installed on a toilet bowl with a basin, comprising: a shell; a nozzle for washing specific parts of the body, movable between a storage position within the shell and an entry position from the shell; a baffle plate rotatable relative to the shell, positioned in front of the nozzle when the nozzle is in the storage position; and a control unit for controlling the movement of the nozzle. The device is characterized in that the nozzle has a first spray outlet for spraying water forward and downward; the baffle plate is in an initial position when the nozzle is in the storage position, and in a first position rotated by a first angle from the initial position when the nozzle is in the entry position; after the hygienic washing device is used, the control unit performs a forward washing action by spraying water from the first spray outlet when the baffle plate is in a second position rotated by a second angle smaller than the first angle from the initial position. During the forward washing action, at least a portion of the baffle plate is positioned closer to the front than the front end of the nozzle.

[0008] According to this sanitary cleaning device, by spraying water from the first spray outlet while the baffle is rotated a second angle from its initial position, it is possible to prevent the water sprayed forward and downward from the first spray outlet from being obstructed by the baffle, thus allowing the water to easily adhere to the front side of the basin. Furthermore, by rotating the baffle a second angle smaller than the first angle, and spraying water from the first spray outlet while at least a portion of the baffle is positioned closer to the front end of the nozzle, it is possible to prevent some of the water sprayed from the first spray outlet from splashing out of the basin or adhering to the closed toilet lid.

[0009] The second invention is a hygienic cleaning device characterized in that, in the first invention, the baffle is rotatable due to the advance and retreat of the nozzle, and the control unit causes the nozzle located in the storage position to enter a predetermined position between the storage position and the entry position, thereby performing the front cleaning action while the baffle is rotated from the initial position to the second position.

[0010] According to this sanitary cleaning device, by providing a baffle that can rotate due to the advance and retreat of the nozzle, the baffle can be rotated even without a separate unit for automatic rotation. Furthermore, by positioning the nozzle to a predetermined position, water easily adheres to the front side of the basin, and by lowering the position of the first spray outlet, it is possible to more effectively prevent water sprayed from the first spray outlet from splashing out of the basin or adhering to the closed toilet lid.

[0011] The third invention is a hygienic cleaning device characterized in that, in the first or second invention, the second angle is smaller than the entry angle of the nozzle relative to the vertical plane.

[0012] According to this sanitary cleaning device, by making the second angle such that water can easily adhere to the front side of the basin, while more reliably preventing a portion of the water sprayed from the first nozzle from splashing out of the basin or adhering to the closed toilet lid.

[0013] The fourth invention is a hygienic cleaning device characterized in that, in any one of the first to third inventions, when the baffle is located in the second position, the lower end of the baffle is located below the center of the first spray outlet or at the same height as the center of the first spray outlet.

[0014] According to this sanitary cleaning device, by making the second position such that water can easily adhere to the front side of the basin, while more reliably preventing a portion of the water sprayed from the first nozzle from splashing out of the basin or adhering to the closed toilet lid.

[0015] The fifth invention is a hygienic cleaning device, characterized in that, in any one of the first to fourth inventions, the spray range of the first spray outlet overlaps with the shield when the shield is in the initial position, and does not overlap with the shield when the shield is in the second position.

[0016] According to this sanitary cleaning device, by making the second position such that water can easily adhere to the front side of the basin, while more reliably preventing a portion of the water sprayed from the first nozzle from splashing out of the basin or adhering to the closed toilet lid.

[0017] The sixth invention is a hygiene cleaning device characterized in that, in any one of the inventions from the first to the fifth, it further comprises: a toilet seat; and a seating detection sensor for detecting a user's sitting on the toilet seat, wherein when the seating detection sensor changes from a state of detecting the user's sitting to a state of not detecting the user's sitting, the control unit performs the forward cleaning action.

[0018] This hygiene cleaning device performs post-use cleaning actions, such as front cleaning, by triggering the user's departure from the seat. This allows post-use cleaning to begin immediately after the device has been used. Consequently, the post-use cleaning can be completed before the next user sits down, minimizing water splashing onto the user.

[0019] The seventh invention is a sanitary cleaning device characterized in that, in any one of the inventions from the first to the sixth, the nozzle further has a second spray outlet that sprays water further rearward than the first spray outlet.

[0020] According to this sanitary cleaning device, by further providing a second spray outlet that sprays water further rearward than the first spray outlet, the water sprayed from the second spray outlet can adhere to the rear side of the basin where the water sprayed from the first spray outlet is difficult to adhere to. This allows water to adhere to a larger area of ​​the basin.

[0021] The eighth invention is a sanitary cleaning device characterized in that, in the seventh invention, the control unit performs a rear cleaning action by spraying water from the second spray outlet while rotating the baffle from the initial position to the second position.

[0022] According to this sanitary cleaning device, by performing a rear cleaning action while rotating the baffle from the initial position to the second position, water can be applied to a larger area of ​​the basin in a shorter time.

[0023] The ninth invention is a hygienic cleaning device characterized in that, in the seventh or eighth invention, the first spray outlet and the second spray outlet are disposed at the front end of the nozzle, and the second spray outlet is disposed to the side of the first spray outlet.

[0024] According to this sanitary cleaning device, by positioning the second spray outlet to the side of the first spray outlet at the front end of the nozzle, the vertical elongation of the nozzle's front end can be suppressed compared to the case where the second spray outlet is positioned above or below the first spray outlet. This shortens the vertical length of the baffle plate and reduces the second angle during the forward washing action. By reducing the second angle, splashing of water from the first spray outlet out of the basin or adhering to the closed toilet lid can be more effectively prevented.

[0025] According to the present invention, a hygienic washing device can be provided in which water can adhere to the front side of the basin from the spray outlet provided at the nozzle. Attached Figure Description

Detailed Implementation

[0027] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, in each drawing, the same reference numerals are used to denote the same constituent elements, and detailed descriptions are omitted where appropriate. Figure 1 It is a perspective view of a toilet flushing device that is schematically represented by the sanitary cleaning device involved in the implementation method. like Figure 1 As shown, the toilet flushing device 900 includes a Western-style toilet bowl 800 and a sanitary washing device 100 mounted thereon. The sanitary washing device 100 has a housing 400, a toilet seat 200, and a toilet lid 300. The toilet seat 200 and the toilet lid 300 are respectively supported by a pivot on the housing 400 and can be opened and closed freely. The toilet bowl 800 has a basin 801.

[0028] In the following description of the implementation method, although "above", "below", "front", "rear", "right side", and "left side" are used, it is as follows: Figure 1 As shown, these directions are those observed from the user seated on toilet seat 200.

[0029] The casing 400 contains a localized cleaning function for cleaning specific areas such as the buttocks of the user seated on the toilet seat 200. This localized cleaning function includes a nozzle 473. The nozzle 473 can move forward and backward between a retracted position within the casing 400 and an entry position from the casing 400. The nozzle 473 enters through a straight track towards the center of the basin 801 located at the lower front of the casing 400, and retracts through a straight track into the interior of the casing 400 located above and behind the basin 801. Furthermore, in... Figure 1 The hygienic cleaning device 100 shown indicates that the nozzle 473 is in the in-entry position.

[0030] The sanitary cleaning device 100 is equipped with a seating detection sensor 404 for detecting when a user sits on the toilet seat 200 (see reference). Figure 2 When the seating detection sensor 404 detects a user sitting on the toilet seat 200, if the user operates the control unit 500 (see reference 500, for example, a remote control)... Figure 2 By operating the nozzle 473, it can be moved into the entry position or backward into the storage position.

[0031] The nozzle 473, when inserted into the housing 400, sprays water (washing water) onto a specific area of ​​the body to clean that area. The nozzle 473 has a buttock-cleaning nozzle 474a, a gentle-cleaning nozzle 474b, and a genital-cleaning nozzle 474c at its tip. The nozzle 473 can spray water from the buttock-cleaning nozzle 474a or the gentle-cleaning nozzle 474b at its tip to clean the buttocks of a user sitting on the toilet seat 200. Alternatively, the nozzle 473 can spray water from the genital-cleaning nozzle 474c at its tip to clean the genital area of ​​a woman sitting on the toilet seat 200. Furthermore, when referred to as "water" in this specification, it includes not only cold water but also heated hot water.

[0032] In the mode of washing the "buttocks", there are, for example, "buttocks washing" and "gentle washing" which washes gently with a softer water flow than "buttocks washing". The nozzle 473 can perform, for example, "buttocks washing", "gentle washing" and "lower body washing".

[0033] Furthermore, in Figure 1 In the nozzle 473 shown, although the lower body cleansing nozzle 474c is positioned closer to the tip of the nozzle 473 than the gentle cleansing nozzle 474b, and the gentle cleansing nozzle 474b is positioned closer to the tip of the nozzle 473 than the buttock cleansing nozzle 474a, the positions of the buttock cleansing nozzle 474a, the gentle cleansing nozzle 474b, and the lower body cleansing nozzle 474c are not limited to these. Furthermore, in Figure 1 Although the nozzle 473 shown has three water outlets, the gentle cleaning water outlet 474b can be omitted, or more than four water outlets can be provided.

[0034] Figure 2 It is a block diagram that schematically represents the main components of the sanitary cleaning apparatus involved in the implementation method. Figure 2 The text simultaneously indicates the main components of both the water system and the electrical system. like Figure 2 As shown, the sanitary cleaning device 100 has a water guiding section 20. The water guiding section 20 has a pipe 20a from a water supply source 10, such as a tap water pipe or a water storage tank, to a nozzle 473. The water guiding section 20 guides water supplied from the water supply source 10 to the nozzle 473 through the pipe 20a. The pipe 20a is formed, for example, by various parts such as a solenoid valve 431, a heat exchanger unit 440, and a flow path switching section 472, as described below, and multiple pipes connecting these various parts.

[0035] A solenoid valve 431 is provided on the upstream side of the water guide section 20. The solenoid valve 431 is an openable and closable solenoid valve that controls the water supply according to the command from the control unit 405 located inside the housing 400. In other words, the solenoid valve 431 opens and closes the pipeline 20a. By keeping the solenoid valve 431 in the open state, water supplied from the water supply source 10 flows in the pipeline 20a.

[0036] A pressure regulating valve 432 is installed downstream of the solenoid valve 431. When the water supply pressure is high, the pressure regulating valve 432 adjusts the pressure in the pipeline 20a to a specified pressure range. When the pressure in the pipeline 20a decreases, the check valve 433 prevents water from flowing back to the upstream side of the check valve 433.

[0037] A heat exchanger unit 440 (heating section) is provided downstream of the check valve 433. The heat exchanger unit 440 has a heater that heats the water supplied from the water supply source 10 to, for example, a predetermined temperature. That is, the heat exchanger unit 440 generates warm water.

[0038] The heat exchanger unit 440 is an instantaneous heating type heat exchanger, such as one using a ceramic heater. Compared to a hot water storage heating type heat exchanger that uses a hot water storage tank, the instantaneous heating type heat exchanger can heat water to a specified temperature in a shorter time. Furthermore, the heat exchanger unit 440 is not limited to an instantaneous heating type heat exchanger; it can also be a hot water storage heating type heat exchanger. Additionally, the heating element is not limited to a heat exchanger; other heating methods, such as microwave heating, can also be used.

[0039] The heat exchanger unit 440 is connected to the control unit 405. The control unit 405 controls the heating unit 440 according to the user's operation of the operation unit 500, thereby heating the water to the temperature set by the operation unit 500.

[0040] A flow sensor 442 is installed downstream of the heat exchanger unit 440. The flow sensor 442 detects the flow rate of water discharged from the heat exchanger unit 440. That is, the flow sensor 442 detects the flow rate of water flowing in the pipe 20a. The flow sensor 442 is connected to the control unit 405. The flow sensor 442 inputs the flow rate detection result to the control unit 405.

[0041] An electrolyzer unit 450 is disposed downstream of the flow sensor 442. The electrolyzer unit 450 electrolyzes tap water flowing inside it to generate a liquid containing hypochlorous acid (functional water). The electrolyzer unit 450 is connected to the control unit 405. The electrolyzer unit 450 generates functional water according to the control of the control unit 405.

[0042] The functional water generated in the electrolytic cell unit 450 can be, for example, a solution containing metal ions such as silver ions and copper ions. Alternatively, the functional water generated in the electrolytic cell unit 450 can also be a solution containing electrolyzed chlorine or ozone. Alternatively, the functional water generated in the electrolytic cell unit 450 can also be acidic or alkaline water.

[0043] A vacuum breaker (VB) 452 is provided downstream of the electrolytic cell unit 450. The vacuum breaker 452 includes, for example, a flow path for water flow; an air intake for introducing air into the flow path; and a valve structure for opening and closing the air intake. For example, when water flows in the flow path, the valve structure blocks the air intake, opening it to introduce air into the flow path while stopping the water flow. That is, when there is no water flow in the water guide section 20, the vacuum breaker 452 introduces air into the pipe 20a. The valve structure, for example, uses a float valve.

[0044] As described above, the vacuum breaker 452 introduces air into the pipe 20a, thereby promoting drainage, for example, the portion of the pipe 20a closer to the downstream end than the vacuum breaker 452. The vacuum breaker 452, for example, promotes drainage from the nozzle 473. In this way, the vacuum breaker 452 discharges water from the nozzle 473 and introduces air into it, thereby, for example, preventing backflow of washing water from the nozzle 473, wastewater accumulated in the basin 801, etc., towards the water supply source 10 (water supply).

[0045] A pressure modulation unit 454 is provided downstream of the vacuum breaker 452. The pressure modulation unit 454 pulses or accelerates the water flow within the pipe 20a of the water guide section 20, causing the water ejected from the buttock-cleaning nozzle 474a, gentle-cleaning nozzle 474b, lower-body-cleaning nozzle 474c of the nozzle 473, and the nozzle cleaning section 478 to pulse. In other words, the pressure modulation unit 454 changes the flow state of the water within the pipe 20a. The pressure modulation unit 454 is connected to the control unit 405. The pressure modulation unit 454 changes the water flow state according to the control of the control unit 405. The pressure modulation unit 454 changes the pressure of the water within the pipe 20a.

[0046] A flow rate adjustment unit 471 is provided downstream of the pressure modulation unit 454. The flow rate adjustment unit 471 adjusts the water pressure (flow rate). A flow path switching unit 472 is provided downstream of the flow rate adjustment unit 471. The flow path switching unit 472 switches the water supply to the nozzle 473 and the nozzle cleaning unit 478. The flow rate adjustment unit 471 and the flow path switching unit 472 can also be provided as a single unit. The flow rate adjustment unit 471 and the flow path switching unit 472 are connected to the control unit 405. The control unit 405 controls the operation of the flow rate adjustment unit 471 and the flow path switching unit 472.

[0047] Downstream of the flow path switching section 472, there is a nozzle 473 and a nozzle cleaning section 478. The nozzle 473 is driven by the nozzle driving section 476 and enters the basin 801 of the toilet 800 or retracts from the basin 801.

[0048] The nozzle cleaning unit 478 sprays functional water or water from the water discharge unit, thereby cleaning the outer peripheral surface (body) of the nozzle 473.

[0049] Additionally, downstream of the flow path switching unit 472, there are a buttock-cleansing flow path 21, a gentle-cleansing flow path 22, and a genital-cleansing flow path 23. These are supplied to the nozzle 473 via the water guide unit 20 with water supplied from the water supply source 10 or functional water generated in the electrolysis unit 450. The buttock-cleansing flow path 21 connects the flow path switching unit 472 to the buttock-cleansing outlet 474a. The gentle-cleansing flow path 22 connects the flow path switching unit 472 to the gentle-cleansing outlet 474b. The genital-cleansing flow path 23 connects the flow path switching unit 472 to the genital-cleansing outlet 474c.

[0050] Additionally, a surface cleaning flow path 24, a first basin spray flow path 25, and a second basin spray flow path 26 are provided downstream of the flow path switching section 472. The surface cleaning flow path 24 guides water supplied from the water supply source 10 or functional water generated in the electrolytic cell unit 450 to the water discharge section of the nozzle cleaning section 478 via the water guide section 20. The first basin spray flow path 25 and the second basin spray flow path 26 guide water supplied from the water supply source 10 or functional water generated in the electrolytic cell unit 450 to the spray outlet 479 (first spray outlet 479a and second spray outlet 479b described later) of the nozzle 473 via the water guide section 20. The water or functional water supplied to the spray outlet 479 is sprayed from the spray outlet 479 into the basin 801. Furthermore, when the second spray outlet 479b is not provided, the second basin spray flow path 26 can be omitted.

[0051] The control unit 405 switches the opening and closing of the following flow paths via the flow path switching unit 472: buttock washing flow path 21, gentle washing flow path 22, genital washing flow path 23, surface cleaning flow path 24, first basin spray flow path 25, and second basin spray flow path 26. In this way, the flow path switching unit 472 switches the state of the multiple spray outlets, such as the buttock washing nozzle 474a, gentle washing nozzle 474b, genital washing nozzle 474c, nozzle cleaning unit 478, and spray outlet 479, between being connected to the pipe 20a and not connected to the pipe 20a.

[0052] Power is supplied from the power circuit 401 to the control unit 405. The control unit 405 controls the operation of the solenoid valve 431, heat exchanger unit 440, electrolytic cell unit 450, pressure modulation unit 454, flow adjustment unit 471, flow path switching unit 472, nozzle drive unit 476, etc., based on signals from the seating detection sensor 404, flow sensor 442, operation unit 500, etc. As a result, the control unit 405 controls the operation of the nozzle 473.

[0053] In addition, the casing 400 may also be appropriately equipped with a "warm air drying function" structure that blows warm air to the "buttocks" of the user sitting on the toilet seat 200 for drying, as well as various structures such as a "deodorizing unit" and an "indoor heating unit". In this case, the exhaust port 407 of the deodorizing unit and the exhaust port 408 of the indoor heating unit are appropriately provided on the side of the casing 400. However, in this invention, a hygienic cleaning function and other additional functional parts are not necessarily required.

[0054] Figure 3 (a) and Figure 3 (b) is a perspective view of the nozzle of the sanitary cleaning device involved in the schematic representation of the embodiment. Figure 4 This is a front view of the nozzle of the hygiene cleaning device involved in the schematic representation of the embodiment. Figure 5 (a) and Figure 5 (b) is a cross-sectional view of the nozzle periphery of the sanitary cleaning device involved in the schematic representation of the embodiment. Figure 5 (a) and Figure 5 (b) indicates that based on Figure 1 The periphery of nozzle 473 on the cross section of line A1-A2 shown.

[0055] like Figure 3 (a) Figure 3 (b) Figure 4 , Figure 5 (a) Figure 5 As shown in (b), the nozzle 473 has, for example, a nozzle head 473a and a nozzle cover 473b. The nozzle head 473a is housed inside the nozzle cover 473b. In other words, the nozzle cover 473b covers the nozzle head 473a.

[0056] The nozzle head 473a is provided with: a water outlet 474 for dispensing water to specific parts of the body (buttocks washing outlet 474a, gentle washing outlet 474b, lower body washing outlet 474c); and a spray outlet 479 for spraying water into the basin 801 (first spray outlet 479a, second spray outlet 479b). The nozzle head 473a is connected to the buttocks washing flow path 21, the gentle washing flow path 22, the lower body washing flow path 23, the first basin spray flow path 25, and the second basin spray flow path 26.

[0057] The nozzle cover 473b is provided with: an opening 475a communicating with the water outlets 474 (buttock cleaning water outlet 474a, gentle cleaning water outlet 474b, lower body cleaning water outlet 474c); and a cutout 475b exposing the spray outlets 479 (first spray outlet 479a, second spray outlet 479b). Figure 4 As shown, the cut portion 475b is, for example, positioned further downward than the center CL1 in the vertical direction of the front end portion 477 of the nozzle 473.

[0058] In this way, by setting the exposed cutout 475b of the first nozzle 479a and the second nozzle 479b to be closer to the bottom than the center CL1 of the front end 477 of the nozzle 473 in the vertical direction, the cutout 475b is not conspicuous when viewed from the user's perspective. As a result, the appearance design is improved.

[0059] The first jet outlet 479a and the second jet outlet 479b will be described in detail below. Figure 5 (a) indicates the state of water being ejected from the first nozzle 479a (i.e., the forward cleaning action described later). Figure 5 (b) indicates the state of water being ejected from the second nozzle 479b (i.e., the rear cleaning action described later).

[0060] The first nozzle 479a and the second nozzle 479b spray water in a mist-like manner, for example. The particle size of the water sprayed from the first nozzle 479a and the second nozzle 479b is, for example, smaller than the particle size of the water sprayed from the buttocks cleansing nozzle 474a, the gentle cleansing nozzle 474b, and the lower body cleansing nozzle 474c. The particle size of the water sprayed from the first nozzle 479a and the second nozzle 479b is, for example, about 400 μm.

[0061] like Figure 5 As shown in (a), the first nozzle 479a opens forward and downward. Water is ejected forward and downward from the first nozzle 479a. More specifically, the first nozzle 479a ejects water relative to the horizontal plane HP at a first ejection angle θ1. The first ejection angle θ1 is the angle formed by the first ejection direction D1 of the water ejected from the first nozzle 479a and the horizontal plane HP. The first ejection direction D1 can be represented, for example, by the centerline of the ejection range R1 of the water ejected from the first nozzle 479a. The first ejection direction D1 can also be represented, for example, by the normal to the first nozzle 479a.

[0062] The first ejection angle θ1 is, for example, greater than the entry angle θ3 of nozzle 473 relative to the horizontal plane HP. The entry angle θ3 is the angle formed by the entry direction ED of nozzle 473 and the horizontal plane HP. In other words, the first ejection outlet 479a ejects water further rearward than the entry direction ED of nozzle 473. The first ejection angle θ1 is an acute angle. The first ejection angle θ1 is, for example, 38 degrees or more and 72 degrees or less.

[0063] like Figure 5 As shown in (b), the second nozzle 479b opens further rearward than the first nozzle 479a. The second nozzle 479b ejects water further rearward than the first nozzle 479a. More specifically, the second nozzle 479b ejects water relative to the horizontal plane HP at a second ejection angle θ2. The second ejection angle θ2 is the angle formed by the second ejection direction D2 of the water ejected from the second nozzle 479b and the horizontal plane HP. The second ejection direction D2 can be represented, for example, by the centerline of the ejection range R2 of the water ejected from the second nozzle 479b. The second ejection direction D2 can also be represented, for example, by the normal to the second nozzle 479b.

[0064] The second ejection angle θ2 is, for example, greater than the entry angle θ3 of nozzle 473 relative to the horizontal plane HP. In other words, the second ejection outlet 479b ejects water further rearward than the entry direction ED of nozzle 473. The second ejection angle θ2 is greater than the first ejection angle θ1. In other words, the second ejection outlet 479b ejects water further rearward than the first ejection outlet 479a. The second ejection angle θ2 is, for example, 72 degrees or more and 90 degrees or less.

[0065] By providing two nozzles 479 (first nozzle 479a and second nozzle 479b) that spray water in different directions in the front-rear direction, a larger area of ​​the basin 801 can be covered by water. More specifically, the first nozzle 479a, which sprays water forward and downward, allows water to adhere to the front side of the basin 801, while the second nozzle 479b, which sprays water further rearward than the first nozzle 479a, allows water to adhere to the rear side of the basin 801. Thus, water sprayed from the second nozzle 479b can adhere to the rear side of the basin 801, where water sprayed from the first nozzle 479a is difficult to adhere to, resulting in a larger area of ​​water adhering to the basin 801.

[0066] In addition, such as Figure 4As shown, the second nozzle 479b is located to the side of the first nozzle 479a. More specifically, the second nozzle 479b does not overlap with the first nozzle 479a in the vertical direction. At least a portion of the second nozzle 479b overlaps with the first nozzle 479a, for example, in the horizontal direction. Furthermore, for example, the first nozzle 479a is located closer to one side (the left side in this example) than the center CL2 of the front end 477 of the nozzle 473 in the horizontal direction, and the second nozzle 479b is located closer to the other side (the right side in this example) than the center CL2 in the horizontal direction.

[0067] Furthermore, the first nozzle 479a can be located closer to the right than the center CL2 of the front end 477 of the nozzle 473 in the left-right direction, and the second nozzle 479b can be located closer to the left than the center CL2 in the left-right direction. In other words, the left-right positions of the first nozzle 479a and the second nozzle 479b can also be reversed.

[0068] In this way, by positioning the second nozzle 479b to the side of the first nozzle 479a, even when the direction of water ejected from the first nozzle 479a is different from the direction of water ejected from the second nozzle 479b, it is possible to prevent water ejected from one nozzle 479 (e.g., the second nozzle 479b) from contacting water ejected from another nozzle 479 (e.g., the first nozzle 479a). This increases the design freedom regarding the direction of water ejection from each nozzle 479. Consequently, water can be ejected further forward from the first nozzle 479a, making it easier for water to adhere to the front side of the basin 801.

[0069] In addition, such as Figure 4 As shown, the first nozzle 479a is located, for example, closer to the top than the second nozzle 479b. More specifically, the center C1 of the first nozzle 479a is located closer to the top than the center C2 of the second nozzle 479b.

[0070] In this way, by configuring the center C1 of the first nozzle 479a to be closer to the top than the center C2 of the second nozzle 479b, it is possible to more reliably prevent water ejected from one nozzle 479 (e.g., the second nozzle 479b) from contacting another nozzle 479 (e.g., the first nozzle 479a).

[0071] In addition, such as Figure 4 As shown, the first nozzle 479a and the second nozzle 479b are provided, for example, at the front end 477 of the nozzle 473. More specifically, the first nozzle 479a and the second nozzle 479b are provided, for example, at the front end 477 of the nozzle 473, closer to the bottom than the center CL1 in the vertical direction.

[0072] In this way, by providing the first spray outlet 479a and the second spray outlet 479b at the front end 477 of the nozzle 473, water can be sprayed further forward from the first spray outlet 479a. As a result, water can more easily adhere to the front side of the basin 801.

[0073] Furthermore, in the embodiment, the second nozzle 479b is provided as needed and can be omitted. In other words, it is sufficient for the nozzle 473 to have at least the first nozzle 479a. When the second nozzle 479b is not provided, the first nozzle 479a is, for example, configured to overlap the center CL2 in the left-right direction of the front end 477 of the nozzle 473.

[0074] Figure 6 (a) and Figure 6 (b) is a cross-sectional view of the nozzle periphery of the sanitary cleaning device involved in the schematic representation of the embodiment. Figure 6 (a) indicates that the nozzle 473 is in the storage position. Figure 6 (b) indicates that nozzle 473 is in the entry position.

[0075] like Figure 6 (a) and Figure 6 As shown in (b), the sanitary cleaning apparatus 100 according to the embodiment includes a baffle 600. The baffle 600 is configured to be rotatable relative to the housing 400.

[0076] like Figure 6 As shown in (a), when the nozzle 473 is in the retracted position, the baffle 600 is in the initial position. When in the initial position, the baffle 600 is located in front of the nozzle 473. Figure 6 As shown in (b), when the nozzle 473 is in the inlet position, the baffle 600 is in the first position. When the baffle 600 is in the first position, it is located above the nozzle 473.

[0077] As the nozzle 473 moves from the storage position to the entry position, the baffle 600 rotates from the initial position to the first position. The first position is the position where the initial position has been rotated by the first angle ψ1.

[0078] In the initial position, the shield 600 is, for example, positioned parallel to the vertical plane VP. In the initial position, the shield 600 may also be tilted relative to the vertical plane VP at an angle greater than 0 degrees and less than 3 degrees. In other words, the angle formed by the first tilt direction T1 of the shield 600 in the initial position and the vertical plane VP is, for example, greater than 0 degrees and less than 3 degrees. The first tilt direction T1 can be represented, for example, by a straight line along the lower extension 602 extending downward from the shaft support portion 601 of the shield 600 in the initial position. The first tilt direction T1 can also be represented, for example, by a straight line connecting the upper and lower ends of the shield 600 in the initial position.

[0079] The first angle ψ1 is the angle formed by the first tilt direction T1 of the shield 600 in the initial position and the second tilt direction T2 of the shield 600 in the first position. The second tilt direction T2 can be represented, for example, by a straight line extending downward from the lower extension 602 of the shield 600 in the first position. The second tilt direction T2 can also be represented, for example, by a straight line connecting the upper end and the lower end of the shield 600 in the first position. The first angle ψ1 is, for example, 25 degrees or more and 45 degrees or less.

[0080] Figure 7 It is a cross-sectional view of the nozzle periphery of the sanitary cleaning device involved in the schematic representation of the embodiment. In this embodiment, the control unit 405 performs post-use cleaning after the sanitary cleaning device 100 has been used. During post-use cleaning, such as... Figure 7 As shown, when the baffle plate 600 is in the second position after rotating by a second angle ψ2 from the initial position, the control unit 405 performs a front cleaning operation that sprays water from the first nozzle 479a.

[0081] The second angle ψ2 is the angle formed by the first tilting direction T1 of the shield 600 in the initial position and the third tilting direction T3 of the shield 600 in the second position. The third tilting direction T3 can be represented, for example, by a straight line extending downward from the lower extension 602 of the shield 600 in the second position, from the axis support 601. The third tilting direction T3 can also be represented, for example, by a straight line connecting the upper end and the lower end of the shield 600 in the second position. The second angle ψ2 is, for example, 3 degrees or more and 25 degrees or less.

[0082] The second angle ψ2 is greater than 0 degrees. The second angle ψ2 is less than the first angle ψ1. That is, during the forward cleaning action (in the second position), the baffle 600 is in a more open state than when the nozzle 473 is in the retracted position (in the initial position), and in a more closed state than when the nozzle 473 is in the entry position (in the first position). In addition, during the forward cleaning action (when the baffle 600 is in the second position), at least a portion of the baffle 600 is located closer to the front than the front end 477 of the nozzle 473.

[0083] In this way, by spraying water from the first nozzle 479a while the baffle plate 600 is rotated from the initial position by a second angle ψ2, it is possible to prevent the water sprayed forward and downward from the first nozzle 479a from being obstructed by the baffle plate 600, making it easier for the water to adhere to the front side of the basin 801.

[0084] Furthermore, by rotating the baffle 600 to a second angle ψ2 that is smaller than the first angle ψ1, water is ejected from the first spray outlet 479a when at least a portion of the baffle 600 is located closer to the front end 477 of the nozzle 473. This prevents a portion of the water ejected from the first spray outlet 479a from splashing out of the basin 801 or adhering to the closed toilet lid 300.

[0085] In this example, the baffle 600 is rotatable due to the forward and backward movement of the nozzle 473. The control unit 405 moves the nozzle 473, which is in the storage position, to a predetermined position between the storage position and the entry position, thereby performing a forward cleaning operation while the baffle 600 is rotated from the predetermined position to the second position.

[0086] In this way, by providing a baffle 600 that can rotate due to the advance and retreat of the nozzle 473, the baffle 600 can be rotated even without a separate unit for automatically rotating it. Furthermore, by positioning the nozzle 473 to a predetermined position, water easily adheres to the front side of the basin 801, and the position of the first spray outlet 479a is lowered, thus more reliably preventing any water sprayed from the first spray outlet 479a from splashing out of the basin or adhering to the closed toilet lid 300.

[0087] like Figure 7 As shown, the second angle ψ2 is, for example, smaller than the entry angle ψ3 of the nozzle 473 relative to the vertical plane VP. The entry angle ψ3 is the angle formed by the entry direction ED of the nozzle 473 and the vertical plane VP. By making the second angle ψ2 such that water can easily adhere to the front side of the basin 801, while more reliably preventing a portion of the water ejected from the first nozzle 479a from splashing out of the basin 801 or adhering to the closed toilet lid 300.

[0088] Additionally, for example, when the baffle 600 is in the second position, the lower end of the baffle 600 is located below or at the same height as the center C1 of the first spray outlet 479a. In other words, the second angle ψ2 is set, for example, to an angle that places the lower end of the baffle 600 below or at the same height as the center C1 of the first spray outlet 479a. By making the second angle ψ2 such an angle (by making the second position such a position), water can easily adhere to the front side of the basin 801, while more reliably preventing a portion of the water sprayed from the first spray outlet 479a from splashing out of the basin 801 or adhering to the closed toilet lid 300.

[0089] Figure 6 (a) and Figure 7 In this context, the ejection range R1 represents the ejection range when water is ejected from the first ejection outlet 479a. For example... Figure 6 As shown in (a), when the baffle 600 is in the initial position, the spray range R1 overlaps with the baffle 600. That is, when the baffle 600 is in the initial position, if water is sprayed from the first spray outlet 479a, it will be obstructed by the baffle 600.

[0090] In contrast, such as Figure 7 As shown, when the baffle 600 is in the second position, the spray range R1 does not overlap with the baffle 600. In other words, the second angle ψ2 is set, for example, to an angle that prevents the spray range R1 of the first nozzle 479a from overlapping with the baffle 600. By making the second angle ψ2 such an angle (by making the second position such a position), water can easily adhere to the front side of the basin 801, while more reliably preventing a portion of the water sprayed from the first nozzle 479a from splashing out of the basin 801 or adhering to the closed toilet lid 300.

[0091] like Figure 4As shown, in this embodiment, the first spray outlet 479a and the second spray outlet 479b are provided at the front end 477 of the nozzle 473. Furthermore, the second spray outlet 479b is located to the side of the first spray outlet 479a. By placing the second spray outlet 479b to the side of the first spray outlet 479a at the front end 477 of the nozzle 473, compared to placing the second spray outlet 479b above or below the first spray outlet 479a at the front end 477 of the nozzle, the elongation of the front end 477 of the nozzle 473 in the vertical direction can be suppressed. This shortens the vertical length of the baffle 600, reducing the second angle ψ2 during the forward washing action. By reducing the second angle ψ2, it is more reliable to prevent a portion of the water sprayed from the first spray outlet 479a from splashing out of the basin 801 or adhering to the closed toilet lid 300.

[0092] Furthermore, the water sprayed from the nozzle 479 during post-use cleaning can also be functional water generated in the electrolytic cell unit 450.

[0093] Figure 8 This is a cross-sectional view of the nozzle periphery of a modified example of the sanitary cleaning device involved in the embodiment, which is a schematic representation. In this embodiment, the sanitary cleaning device 100 may also include a unit (drive unit) for automatically rotating the baffle 600. In this case, such as... Figure 8 As shown, the control unit 405 can also perform a front cleaning operation by rotating the baffle 600 from the initial position to the second position via the drive unit instead of allowing the nozzle 473 to enter.

[0094] Even in this example, by spraying water from the first nozzle 479a while the baffle 600 is rotated from its initial position by a second angle ψ2, it is possible to prevent the water sprayed forward and downward from the first nozzle 479a from being obstructed by the baffle 600, making it easier for the water to adhere to the front side of the basin 801.

[0095] Figure 9 This is a flowchart illustrating an example of the operation of the hygiene cleaning apparatus involved in the embodiment. The following is for reference Figure 9 An example of the process is described for post-use cleaning when only water is sprayed from the first nozzle 479a (forward cleaning action).

[0096] like Figure 9 As shown, in this example, when the seating detection sensor 404 changes from a state where seating is detected to a state where seating is not detected (step S101: Yes), the control unit 405 moves the nozzle 473 to a predetermined position (step S102). This allows the baffle 600 to rotate from its initial position to its second position.

[0097] By initiating post-use cleaning actions, such as front cleaning, as when the user leaves their seat, post-use cleaning can begin immediately after the user has finished using the hygiene cleaning device 100. This allows the post-use cleaning to be completed before the next user sits down, thus preventing water from splashing onto the user.

[0098] Furthermore, the opportunity for post-use cleaning is not limited to the user leaving the seat. For example, the control unit 405 can also perform post-use cleaning based on the user's exit from the restroom or operation of the toilet cleaning button.

[0099] When nozzle 473 reaches the designated position, control unit 405 begins to spray water from first nozzle 479a (forward cleaning operation) (step S103). When the water spraying from first nozzle 479a has been carried out for a designated time (e.g., 6 seconds) (step S104: Yes), control unit 405 stops the water spraying from first nozzle 479a (forward cleaning operation) (step S105).

[0100] When the water ejection from the first nozzle 479a is stopped, the control unit 405 retracts the nozzle 473 to the storage position (step S106).

[0101] Step S103 can also be executed after step S102 begins and before step S102 ends. That is, the control unit 405 can start spraying water from the first spray outlet 479a while the nozzle 473 is entering. Alternatively, step S103 can also be executed before step S102. That is, the control unit 405 can start spraying water from the first spray outlet 479a before the nozzle 473 enters.

[0102] Step S105 can also be executed after step S106. That is, the control unit 405 can also stop the water ejection from the first nozzle outlet 479a after the nozzle 473 retracts. Alternatively, step S105 can also be executed after the start of step S106 and before the end of step S106. That is, the control unit 405 can stop the water ejection from the first nozzle outlet 479a while retracting the nozzle 473.

[0103] Figure 10 This is a flowchart illustrating another example of the operation of the hygiene cleaning apparatus involved in the embodiment. The following is for reference Figure 10 An example of the process for spraying water from the first nozzle 479a (forward cleaning action) and spraying water from the second nozzle 479b (rear cleaning action) during post-use cleaning is described.

[0104] like Figure 10 As shown, in this example, when the seating detection sensor 404 changes from a state where seating is detected to a state where seating is not detected (step S201: Yes), the control unit 405 starts spraying water from the second nozzle 479b (rear cleaning action) (step S202).

[0105] When water begins to be ejected from the second nozzle 479b, the control unit 405 moves the nozzle 473 to a predetermined position while water is being ejected from the second nozzle 479b (step S203). This allows the baffle plate 600 to be rotated from its initial position to its second position. That is, while rotating the baffle plate 600 from its initial position to its second position, the control unit 405 performs a rear cleaning operation following the ejection of water from the second nozzle 479b.

[0106] In this way, by performing a rearward rinsing action while rotating the baffle 600 from the initial position to the second position, water can be applied to a larger area of ​​the basin 801 in a shorter time.

[0107] When the nozzle 473 enters the designated position, the control unit 405 stops the water spraying from the second nozzle 479b (rear cleaning action) (step S204) and starts the water spraying from the first nozzle 479a (front cleaning action) (step S205).

[0108] When water from the first nozzle 479a is ejected for a predetermined time (e.g., 6 seconds) (step S206: Yes), the control unit 405 stops the ejection of water from the first nozzle 479a (forward cleaning action) (step S207) and starts the ejection of water from the second nozzle 479b (rear cleaning action) (step S208).

[0109] When water is started to be ejected from the second nozzle 479b, the control unit 405 retracts the nozzle 473 to the storage position while water is being ejected from the second nozzle 479b (step S209).

[0110] When the nozzle 473 retracts to the storage position, the control unit 405 stops the spraying of water from the second spray outlet 479b (rear cleaning action) (step S210).

[0111] Step S202 can also be executed after step S203 begins and before step S203 ends. That is, the control unit 405 can also start spraying water from the second spray outlet 479b while the nozzle 473 is being inserted.

[0112] Furthermore, steps S204 and S205 can also be executed after step S203 begins and before step S203 ends. That is, the control unit 405 can either stop the water jetting from the second nozzle 479b while the nozzle 473 is being inserted, or it can start the water jetting from the first nozzle 479a while the nozzle 473 is being inserted.

[0113] Step S210 can also be executed after step S209 begins and before step S209 ends. That is, the control unit 405 can also stop the water ejection from the second nozzle 479b while retracting the nozzle 473.

[0114] Furthermore, steps S207 and S208 can also be executed after step S209 begins and before step S209 ends. That is, the control unit 405 can either stop the water jetting from the first nozzle outlet 479a while retracting the nozzle 473, or start the water jetting from the second nozzle outlet 479b while retracting the nozzle 473.

[0115] Furthermore, steps S202 and S204 can be performed as needed and may be omitted. That is, a subsequent cleaning action performed before the preceding cleaning action can be omitted. Similarly, steps S208 and S210 can be performed as needed and may be omitted. That is, a subsequent cleaning action performed after the preceding cleaning action can be omitted. In the embodiment, the subsequent cleaning action is preferably performed either before or after the preceding cleaning action.

[0116] In addition, in this embodiment, the control unit 405 can also perform pre-use cleaning before using the hygiene cleaning device 100. More specifically, the control unit 405 can also perform pre-use cleaning, for example, when the seating detection sensor 404 changes from a state where seating is not detected to a state where seating is detected.

[0117] Furthermore, the pre-use cleaning is not limited to the user sitting down. The control unit 405 can also perform pre-use cleaning based on the user's entry into the restroom or operation of the button to open the toilet lid 300. Pre-use cleaning can be performed in conjunction with the above-mentioned... Figure 9 and Figure 10 The process shown is the same as the one performed.

[0118] As described above, according to the embodiment, a hygienic cleaning device 100 can be provided in which a baffle plate 600 is provided in front of the nozzle 473, and water can be adhering to the front side of the basin 801 from the spray outlet 479 provided in the nozzle 473.

Furthermore, as long as it is technically feasible, the elements of the aforementioned embodiments can be combined, and any combination techniques that include the features of the present invention are also included within the scope of the present invention.
