Description

  The present invention relates to a sanitary washing apparatus, and more particularly, to a sanitary washing apparatus that discharges washing water toward a human body part.

  2. Description of the Related Art Conventionally, a sanitary washing device that cleans a human body part by heating water in a heating tank and discharging the heated hot water from a nozzle toward the body part is known. Such a sanitary washing device has a function of washing the nozzle.

  The nozzle cleaning function includes, for example, “pre-nozzle cleaning” performed before the sanitary cleaning device performs local cleaning, “post-nozzle cleaning” performed after performing local cleaning, and periodic cleaning of the nozzles in a predetermined cycle. “Periodic nozzle cleaning”, “manual nozzle cleaning” in which the user performs cleaning of the nozzles by giving instructions to the sanitary cleaning device. The sanitary washing device can perform at least any nozzle washing.

  The timing at which the sanitary cleaning device performs nozzle cleaning is, for example, as follows.

  In “front nozzle cleaning”, there are a case where the human body detection sensor provided in the sanitary washing device detects the user's entry, the case where the seating detection sensor provided in the sanitary washing device detects the user's sitting, and the like.

  In “rear nozzle cleaning”, the user sits on the sanitary washing device, the sanitary washing device cleans the user's local area, and a predetermined time after the seating detection sensor provided in the sanitary washing device detects the user's separation. For example, when it has passed. Instead of the detection result of the seating detection sensor, the post nozzle cleaning may be performed when a predetermined time has elapsed after the human body detection sensor no longer detects the user.

  In the “periodic nozzle cleaning”, there is a case where a predetermined time has elapsed since the previous nozzle cleaning was performed.

  In “manual nozzle cleaning”, there is a case where the sanitary washing device receives a predetermined operation by the user via a remote control or a button provided in the sanitary washing device. This is performed when the user intentionally performs nozzle cleaning.

  For example, Patent Literature 1 discloses a sanitary cleaning device that sets the cleaning time for the previous nozzle cleaning based on the idle time from the previous cleaning operation to the current cleaning operation.

Japanese Patent No. 3503489

  The nozzle cleaning of the sanitary cleaning device may be frequently performed in a short time. For example, in a public environment such as a station or a department store, a user may rush to a toilet room, and users who use sanitary washing devices may be replaced one after another. When the sanitary washing apparatus is equipped with at least front nozzle washing and rear nozzle washing, the sanitary washing apparatus is used by another user entering the room after performing the rear nozzle washing based on the use of the user with the sanitary washing apparatus. Perform pre-nozzle cleaning. If the user changes one after another, the interval between the subsequent nozzle cleaning and the previous nozzle cleaning tends to be shortened.

  For sanitary cleaning equipment in a public environment, the user has no knowledge about the detailed operation of the sanitary cleaning equipment, so even if nozzle cleaning is performed normally, the user is unaware of whether or not nozzle cleaning is performed. There is also a fear. Therefore, when the sanitary cleaning device is equipped with at least rear nozzle cleaning and manual nozzle cleaning, even if the rear nozzle cleaning for the user who used the previous sanitary cleaning device was performed, the user who newly entered the toilet room In order to ensure that the nozzle is in a clean state, a manual nozzle cleaning command may be issued to the sanitary cleaning device before performing local cleaning after sitting. That is, the post nozzle cleaning and the manual nozzle cleaning are continuously performed.

  It is thought that the more clean the nozzle is, the more clean it can be maintained, but the nozzle is originally cleaned by a single nozzle cleaning. There is little need to clean a nozzle that is already clean many times in a short time. If the nozzle cleaning is performed excessively, an excessive load is applied to the sanitary cleaning device, and water for cleaning the nozzle is also used excessively. It is an object of the present invention to provide a sanitary cleaning device that reduces such redundant nozzle cleaning.

By discharging from the toilet, local parts such as a user's butt seated on the toilet seat 8 are washed. Moreover, the inside of the sanitary washing apparatus 4 of this embodiment has a function of sterilizing and cleaning the nozzle 12 with sterilizing water generated by the electrolytic cell unit 32 (not shown in FIG. 1). The nozzle 12 may be washed with water that does not contain a sterilizing component.

  As shown in FIG. 2, the sanitary washing device 4 includes a power circuit 13, and power is supplied through the power circuit 13. When the power is supplied, the control unit 20 can make a determination for issuing various commands.

  The sanitary washing device 4 has a flow path 26 extending from the water supply source 24 to the nozzle 12. On the upstream side of the flow path 26, an electromagnetic valve 28 that is communicably connected to the control unit 20 is provided. The electromagnetic valve 28 is an electromagnetic valve that can open and close the flow path 26, and controls the supply of water based on a command from the control unit 20.

3 and 4 are flowcharts illustrating the processing steps of the sanitary washing device 4 of this embodiment. The process steps will be described by taking the user who has used the sanitary washing device 4 in the past as the first user, the user who will use this time as the second user, and the second user as an example. Among the first users, in particular, the previous user is the first user 1, the previous user is the first user 2, and the previous X user is the first user X. Note that the first user and the second user may be different persons or may be the same person. Similarly, the arbitrary first user M and the arbitrary first user N may be different persons or may be the same person.

  In FIG. 3, the control unit 20 determines the presence of the second user based on at least one of the detection result of the human body detection sensor 42 passed by the user detection unit 40 and the detection result of the seating detection sensor 44. . When it is determined that the second user does not exist (does not exist), the control unit 20 waits until the second user exists (step S101: N). If it determines with the 2nd user existing (step S101: Y), the control part 20 will measure the time TA (step S102). In addition, when it determines with the control part 20 having a 2nd user, it can implement front nozzle washing | cleaning.

  The operation unit 22 waits for an input command for performing local cleaning by the second user (step S103). The operation unit 22 receives at least one of the detection result of the human body detection sensor 42 and the detection result of the seating detection sensor 44 passed by the user detection unit 40 without receiving an input command for performing local cleaning by the second user. If the control unit 20 determines that the second user is not present, the process is terminated because the nozzle is not used and there is no need for post-nozzle cleaning (step S103: N). When the operation unit 22 receives an input command for performing local cleaning by the second user, the control unit 20 performs local cleaning. At this time, there is a possibility that the second user issues an input command for performing manual nozzle cleaning before issuing an input command for performing local cleaning.

  After the control unit 20 performs local cleaning (step S103: Y), the control unit 20 at least one of the detection result of the human body detection sensor 42 and the detection result of the seating detection sensor 44 delivered by the user detection unit 40. The absence of the second user is determined based on one (step S104). When it is determined that the second user exists, the control unit 20 waits until the second user does not exist (step S104: N).

  When the control unit 20 determines that the second user is not present (step S104: Y), the control unit 20 performs continuous use determination for determining a state in which the second user is continuously used within a predetermined time (step S105). The determination of continuous use will be described later with reference to FIG.

  If the control unit 20 determines that there is continuous use (step S106: Y), the post-nozzle cleaning is not performed. On the other hand, if the controller 20 determines that there is no continuous use (step S106: N), it performs post-nozzle cleaning (step S107). Thereafter, the control unit 20 measures time TB (step S108).

  FIG. 4 is a detailed flowchart of the continuous use determination in step S105.

  If the difference between the time TA measured after confirming the presence of the second user and the time TB measured after confirming the absence of the first user is smaller than the predetermined time (step S120: Y), It is determined that the sanitary washing device 4 is in a continuously used state (step S121). On the other hand, if the difference is not less than the predetermined time (step S120: N), it is determined that the sanitary washing device 4 is not in a continuously used state (step S122). The sanitary washing device 4 continues even when the difference between the time TA measured after confirming the presence of the second user and the time TB measured after confirming the absence of the first user is equal to the predetermined time. It may be determined that the device is being used.

  Here, the time TB at the first user 1 is set as time TB1, the time TB at the first user 2 is set as time TB2, and the time TB at the first user X is set as time TBx. The difference between the time TA at the second user and the time TBm at the first user M M times before may be compared with a predetermined time. The predetermined time and how many times the first user is compared with the first user may be a value set in advance or a value that can be set by the operation unit 22. For example, if the predetermined time is 3 minutes and compared with the first user 5 five times before as viewed from the second user, the difference between the time TA at the second user and the time TB5 at the first user 5 is less than 3 minutes. When it is small, it is determined that there is continuous use.

  Thus, based on the 1st condition regarding the 1st user detected by the user detection part 40, and the 2nd condition regarding the 2nd user detected by the user detection part 40 after the 1st user, it is continuous within predetermined time. The sanitary washing device 4 carries out continuous use determination for determining the state to be used. The first situation is the first time when the absence of the first user is determined, and the second situation is the second time when the existence of the second user is determined. When the difference between the second time and the first time is equal to or smaller than the predetermined value, the sanitary washing device 4 performs the post-nozzle cleaning for the second user by determining that the state is continuously used. Absent. If it is determined that there is no continuous use, the sanitary washing device 4 performs post-nozzle cleaning for the second user.

  Thereby, the sanitary washing apparatus 4 can determine whether there is a possibility that redundant nozzle washing is performed while local washing is not performed. The sanitary cleaning device 4 does not perform subsequent nozzle cleaning if it is determined that redundant nozzle cleaning is performed, and therefore reduces the need for redundant nozzle cleaning in a short period when the nozzle is not used for local cleaning. Can do. On the other hand, if it is determined that redundant nozzle cleaning is not performed, the subsequent nozzle cleaning is performed, so that the nozzle can be kept clean.

[Embodiment 2]
5 and 6 are other flowcharts illustrating the processing steps of the sanitary washing device 4 of the present embodiment.

  In FIG. 5, compared with FIG. 3, there is no step S108 for measuring the time TB. Also, step S105 for performing continuous use determination is step S205.

  FIG. 6 is a detailed flowchart of the continuous use determination in step S205.

  If the difference between the time TA measured after confirming the presence of the second user and the time TA measured after confirming the presence of the first user is smaller than the predetermined time (step S220: Y), the control unit 20 It is determined that the cleaning device 4 is in a continuously used state (step S121). On the other hand, if the difference is not less than the predetermined time (step S220: N), it is determined that the sanitary washing device 4 is not in a state of being used continuously (step S122). Even when the difference between the time TA measured after confirming the presence of the second user and the time TA measured after confirming the presence of the first user is equal to the predetermined time, the sanitary washing device 4 continues. It may be determined that the device is being used.

  Here, the time TA of the first user 1 is set as time TA1, the time TA of the first user 2 is set as time TA2, and the time TA of the first user X is set as time TAx. The difference between the time TA of the second user and the time TAm of the first user M M times before may be compared with a predetermined time. The predetermined time and how many times the first user is compared with the first user may be a value set in advance or a value that can be set by the operation unit 22. For example, if the predetermined time is 3 minutes and the first user 5 is compared 5 times before the second user, the difference between the time TA at the second user and the time TA5 at the first user 5 is less than 3 minutes. When it is small, it is determined that there is continuous use.

  Thus, based on the 1st condition regarding the 1st user detected by the user detection part 40, and the 2nd condition regarding the 2nd user detected by the user detection part 40 after the 1st user, it is continuous within predetermined time. The sanitary washing device 4 carries out continuous use determination for determining the state to be used. The first situation is a first time when the presence of the first user is determined, and the second situation is a second time when the presence of the second user is determined. When the difference between the second time and the first time is equal to or smaller than the predetermined value, the sanitary washing device 4 performs the post-nozzle cleaning for the second user by determining that the state is continuously used. Absent. If it is determined that there is no continuous use, the sanitary washing device 4 performs post-nozzle cleaning for the second user.

  Thereby, the sanitary washing apparatus 4 can determine whether there is a possibility that redundant nozzle washing is performed while local washing is not performed. The sanitary cleaning device 4 does not perform subsequent nozzle cleaning if it is determined that redundant nozzle cleaning is performed, and therefore reduces the need for redundant nozzle cleaning in a short period when the nozzle is not used for local cleaning. Can do. On the other hand, if it is determined that redundant nozzle cleaning is not performed, the subsequent nozzle cleaning is performed, so that the nozzle can be kept clean.

[Other embodiments]
A user who has used the sanitary washing device 4 in the past is a first user, a user who is using this time is a second user, and a user who is using the sanitary washing device 4 is a third user. As another embodiment, the control unit 20 controls the pre-nozzle cleaning for the third user after performing the local nozzle cleaning for the third user after controlling the post-nozzle cleaning for the second user.

  Specifically, after the control unit 20 determines that the second user performs post-nozzle cleaning in the current local cleaning, the user detection unit 40 detects the presence of the third user, Do not perform pre-nozzle cleaning before performing local cleaning. Accordingly, when the third user newly uses the sanitary washing device 4 following the second user, the front nozzle cleaning for the third user is not performed following the rear nozzle cleaning for the second user. Therefore, it is possible to reduce the redundant nozzle cleaning while the operation is not performed.

  After determining that the second nozzle cleaning is not performed in the current local cleaning for the second user, the control unit 20 performs the local cleaning for the third user when the user detection unit 40 detects the presence of the third user. Prior to performing the pre-nozzle cleaning. As a result, when the third user newly uses the sanitary washing device 4 following the second user, even if the second user uses local cleaning, the nozzle before the third user uses local cleaning. Is clean. In addition, redundant nozzle cleaning can be reduced while local cleaning is not performed.
