Abstract

<P>PROBLEM TO BE SOLVED: To allow a user to positively recognize a shift to rinsing washing only with wash water from washing with washing liquid. <P>SOLUTION: This device comprises a washing liquid holding part 6 for holding washing liquid such as a cleanser, and a washing liquid injection part for injecting the washing liquid from the washing liquid holding part into a water supply line for supplying wash water to a washing nozzle part. The device is constituted to perform the rinsing washing only with wash water following the washing liquid washing with the wash water mixed with the washing liquid. The supply of wash water in an initial stage of a shift from the washing liquid washing to the rinsing washing is thereby stopped or reduced to a small quantity only for a short time. With the supply of wash water thus stopped or reduced to a small quantity, the user can recognize the shift to the rinsing washing. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a local cleaning apparatus for cleaning a local body part.

  The local cleaning device has been cleaning the local area only with hot water, but recently, in order to perform more hygienic cleaning, a cleaning liquid such as a detergent is mixed with the hot water for cleaning and sprayed from the cleaning nozzle. What you do is provided.

In this cleaning liquid cleaning, in order to wash away the cleaning liquid components in the flow path from the cleaning nozzle to the cleaning nozzle and prevent the cleaning liquid from adhering to the cleaning liquid, use cleaning water not mixed with the cleaning liquid. Rinse is performed to “rinse”, but whether or not the user can recognize whether or not the cleaning liquid cleaning has shifted to the rinsing cleaning depends on the user's sense. I sometimes didn't realize that it was migrated.

  The present invention has been invented in view of the above-mentioned conventional problems, and provides a local cleaning device that allows a user to clearly recognize that the cleaning liquid cleaning has shifted to the rinsing cleaning using only the cleaning water. Is an issue.

  In order to solve the above problems, a local cleaning apparatus according to the present invention includes a cleaning liquid holding unit that holds a cleaning liquid such as a detergent, and a water supply path that supplies cleaning water to the cleaning nozzle unit from the cleaning liquid holding unit to the water supply path. In a local cleaning device that includes a cleaning liquid injection unit for injecting a cleaning liquid into the cleaning liquid and rinses only with the cleaning water following the cleaning liquid cleaning with the cleaning liquid mixed, the cleaning at the initial stage of the transition from the cleaning liquid cleaning to the rinsing cleaning It is characterized in that the water supply is stopped or reduced to a small amount for a short time. The user can recognize that the cleaning water supply has been stopped or a small amount has been transferred to the rinse cleaning.

  When the cleaning nozzle expands and contracts depending on the water pressure, it is preferable that the time to stop or reduce the supply of the cleaning water at the initial transition from cleaning liquid cleaning to rinse cleaning is shorter than the time required for the cleaning nozzle to shrink. . Even when the water pressure from the water source is low, it is possible to shift to rinsing and cleaning.

  Further, the supply amount of the cleaning water may be different between the cleaning liquid cleaning and the rinsing cleaning. The user can more clearly recognize the transition to rinsing.

  Furthermore, for those equipped with an air pump that mixes air into the cleaning water, even if the amount of air mixed in the air pump differs between cleaning liquid cleaning and rinsing cleaning, the user can move to rinsing cleaning more clearly. It will be recognized.

  According to the present invention, when rinsing is performed following cleaning liquid cleaning, since the supply of cleaning water is stopped or small in the initial stage of rinsing cleaning, the user can surely recognize that the rinsing cleaning has been started. . Moreover, since it can apply also to what performs only opening and closing of a water supply valve, without using a pump for washing water supply, it is low-cost.

  Hereinafter, the present invention will be described in detail based on an example of an embodiment. The basic configuration as a local cleaning device is substantially the same as the conventional example, and a local cleaning device main body A having a local cleaning mechanism as shown in FIG. An operation unit 2 for a user to select and operate a cleaning method, a toilet seat 3 for a user to sit, a toilet lid 4, a cleaning nozzle unit 5, an agent tank 6 that is a cleaning liquid holding unit for storing cleaning liquid, and a seat A control circuit C (see FIG. 3) for controlling a toilet seat temperature, a washing water temperature, a washing flow rate, and the like according to a signal from the operation unit 2 is provided.

  The piping system in this local cleaning apparatus is shown in FIG. In a water supply path 10 that connects a water source 1 such as a water supply and the cleaning nozzle unit 5, a hot water tank 8 provided with a water supply valve 9, a heater H for heating the water supply, a mixing branch plug 12 for injecting cleaning liquid, and a flow path switching valve 20. Are inserted in this order. The agent tank 6 and the mixing branch plug 12 are connected by an agent supply path 13, and the agent supply path 13 is inserted with an agent pump 11 on the agent tank 6 side and a check valve 14 on the mixing branch plug 12 side. The agent pump 11 and the mixing branch plug 12 constitute an agent injection means.

  The cleaning nozzle section 5 at the end of the water supply path 10 includes a nozzle cleaning nozzle 54 that injects cleaning water toward both nozzles 51 and 52 in addition to the buttocks cleaning nozzle 51 and the bidet cleaning nozzle 52. The butt washing nozzle 51 and the bidet washing nozzle 52 are formed such that the washing water is discharged after being expanded by water pressure, and is shrunk by a built-in spring when the supply of the washing water is stopped.

  The water supply valve 9, the heater H, the agent pump 11, and the flow path switching valve 20 are under the control of the control circuit C and operate according to the output from the control circuit C. When the execution is instructed, the control circuit C opens the water supply valve 9 to start supplying the cleaning water, and simultaneously drives the agent pump 11 to start supplying the cleaning liquid, and supplies the cleaning water mixed with the cleaning liquid to the cleaning nozzle unit. 5 is supplied. The control circuit C stops the agent pump 11 at the time when the required time T1 has elapsed or when the cleaning liquid cleaning instruction operation to the operation unit 2 is lost, and the control circuit C shifts to the rinsing cleaning for a predetermined time T2 using only cleaning water. However, as shown in FIG. 1, the control circuit C closes or throttles the water supply valve 9 for a certain time T3 (for example, 1 second) from the start of the rinsing cleaning so that the cleaning water discharged from the cleaning nozzle unit 5 is discharged. Decrease the water strength of the water, and then return to the original water strength.

  The time T3 is set shorter than the time required for the cleaning nozzles 51 and 52 that expand and contract due to water pressure to contract. By setting such a time, even when it takes time to extend the cleaning nozzles 51 and 52 and discharge the cleaning water, the water pressure of the water source 1 can be accurately shifted to rinsing. it can.

  As shown in FIG. 4, the amount of water discharged from the cleaning nozzle unit 5 may be changed. In particular, it is also preferable to change the amount of water between the cleaning liquid cleaning period T1 and the rinsing cleaning period T2 with cleaning water.

  Further, as shown in FIG. 5, in the case where the air pump 23 for mixing the air into the cleaning water is used, the amount of air mixing is different between the cleaning liquid cleaning period T1 and the rinsing cleaning period T2 with the cleaning water. Good.

It is operation | movement explanatory drawing of the other example same as the above. It is a block diagram of another example. It is operation | movement explanatory drawing same as the above.
