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 out 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, the cleaning water not mixed with the cleaning liquid is used. The rinsing is performed by flowing, but in the case where the cleaning nozzle is blown out by the pressure of the cleaning water supplied against the spring by the pressure of the cleaning water supplied, the following problems are caused. You may be invited.

  That is, when the cleaning liquid is supplied to the cleaning nozzle in order to wash away the cleaning liquid components after the cleaning liquid is flown in a state where no person is seated, the cleaning water extends from the spout that extends upward and faces the cleaning nozzle. The flow rate of the cleaning water to be supplied is reduced so as not to blow out high. At this time, since it would be expensive to install a flow rate adjustment valve, etc., the flow rate switching valve for switching the destination of the cleaning water is kept at a position where the port leading to the cleaning nozzle is slightly opened. Squeezed.

However, more washing water than the design flow rate is supplied to the washing nozzle due to variations in the drive system from the stepping motor for driving the flow path switching valve to the flow path switching valve, and variations in the components of the flow path switching valve itself. Although it flows in and does not spout out from the spout, it may lead to a situation where the cleaning nozzle extends against the spring. When the cleaning nozzle is extended other than during the local cleaning, the user may feel uneasy and feel uncomfortable.

  The present invention has been invented in view of the above-described conventional problems, and when rinsing is performed by supplying cleaning water after cleaning with a cleaning liquid, the amount of cleaning water supplied to the cleaning nozzle can be reliably reduced at low cost. It is an object of the present invention to provide a local cleaning device that can be maintained at a high level.

  In order to solve the above problems, a local cleaning device according to the present invention selectively supplies cleaning water from a cleaning nozzle that expands and contracts according to water pressure, a non-stretchable cleaning nozzle, and cleaning water from a water supply path to these cleaning nozzles. Cleaning liquid cleaning with cleaning water mixed with cleaning liquid, comprising a flow path switching unit, a cleaning liquid holding unit that holds cleaning liquid such as detergent, and a cleaning liquid injection unit that injects the cleaning liquid from the cleaning liquid holding unit into the water supply path In a local cleaning apparatus having a mode and a rinse cleaning mode for rinsing the cleaning liquid in the cleaning nozzle following the cleaning liquid cleaning mode, a part of the cleaning water supplied to the non-stretchable cleaning nozzle is expanded and contracted A non-stretchable cleaning mode is provided for the rinsing cleaning mode following the cleaning liquid mode that is supplied to the cleaning nozzle that expands and contracts the cleaning water mixed with the cleaning liquid. It is characterized in that it is made in the supply of washing water to Le. The rinsing with respect to the expansion / contraction type cleaning nozzle is performed by diverting a part of the cleaning water supplied to the non-extension / contraction type cleaning nozzle to the expansion / contraction type cleaning nozzle.

  At this time, it is preferable that a heater for heating the cleaning water is provided in the water supply path, and the cleaning water supplied in the rinse cleaning mode is heated to the maximum by the heater. The washing liquid can be surely washed away.

  In the present invention, since the rinsing cleaning for the expansion / contraction type cleaning nozzle is performed by diverting a part of the cleaning water supplied to the non-extension / contraction type cleaning nozzle to the expansion / contraction type cleaning nozzle, the rinsing cleaning is often performed in the expansion / contraction type cleaning nozzle. The cleaning water does not flow in, and the telescopic cleaning nozzle does not extend, and there is no need to increase the accuracy of the flow path switching unit or provide a separate flow path adjustment valve. And 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. A water supply valve 9, a heater H for heating water supply, a mixing branch plug 12 for injecting cleaning liquid, and a flow path switching valve 20 are inserted in this order into a water supply path 10 that connects a water source 1 such as a water supply and the cleaning nozzle unit 5. is there. 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.

  As shown in FIG. 4, the cleaning nozzle portion 5 at the end of the water supply path 10 includes a toilet cleaning nozzle 53 that injects cleaning water on the inner surface of the toilet, in addition to the buttocks cleaning nozzle 51 and the bidet cleaning nozzle 52, and these nozzles 51-53, in particular, a nozzle cleaning nozzle 54 for injecting cleaning water toward the buttocks cleaning nozzle 51 and the bidet cleaning nozzle 52, and two of the buttocks cleaning nozzle 51 and the bidet cleaning nozzle 52 are provided with hydraulic pressure. In this case, the cleaning water is discharged after the water is extended, and if the supply of the cleaning water is stopped, the spring is retracted.

  The flow path switching valve 20 is for distributing the cleaning water (including the one in which the cleaning liquid is mixed) flowing through the water supply path 10 to the nozzles 51 to 54, as shown in FIG. A cylindrical needle 22 is also arranged in a cylindrical needle case 21 so as to be rotatable about its axis, and the needle case 21 has a water inlet port 23 connected to the water supply path 10 on one end side in the axial direction. In addition, four discharge ports 24 (three of which are shown in the figure) connected to the nozzles 51 to 54 are provided on the outer peripheral surface.

  The needle 22 has an opening at one end surface on the water inlet port 23 side and is provided with four ports 25 (three of which are shown in the figure) on the outer peripheral surface. The needle 22 is rotated by a stepping motor or the like. Is changed, the discharge destination of the cleaning water that has entered the needle case 21 from the water inlet port 23 is switched to the nozzles 51 to 54.

  Further, an O-ring 26 for preventing water leakage is disposed on the outer peripheral surface of the needle 22. However, the O-ring 26 is disposed only at both ends of the needle 22, and originally the O-ring 26 is also disposed at a position where the discharge ports 24 and 24 are partitioned. When washing water is flowing through a certain discharge port 24, a small amount of washing water (see FIG. 6) is also diverted to other discharge ports 24 through the clearance between the outer peripheral surface of the needle 22 and the inner peripheral surface of the needle case 21. It is supposed to end.

  Here, 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, but according to the water pressure. At the time of rinsing after flowing the cleaning water mixed with the cleaning liquid to the buttocks cleaning nozzle 51 or the bidet cleaning nozzle 52 that performs expansion and contraction, the control circuit C responds to the water pressure from the buttocks cleaning nozzle 51 or the bidet cleaning nozzle 52 to be rinsed. Rinsing cleaning water is supplied by switching to another nozzle that does not expand and contract, that is, the toilet cleaning nozzle 53 or the nozzle cleaning nozzle 54. As a result, most of the rinse water for rinsing is sent to the toilet cleaning nozzle 53 or the nozzle cleaning nozzle 54 which has been switched, and a part of the clearance is provided between the outer peripheral surface of the needle 22 and the inner peripheral surface of the needle case 21 described above. Therefore, the rinsing operation can be completed without hindrance.

  Moreover, the flow rate of the washing water flowing through the buttocks washing nozzle 51 and the bidet washing nozzle 52 at this point is kept small regardless of the variation in the drive system of the needle 22 and the variation in the flow rate switching valve 20 itself. For this reason, there is no possibility that the buttocks cleaning nozzle 51 or the bidet cleaning nozzle 52 extends against the spring by water pressure.

  In the case of rinsing, the washing water may be sent to the toilet cleaning nozzle 53 or the nozzle cleaning nozzle 54. However, in the former case, the cleaning liquid adhering to the inner surface of the toilet bowl may be washed away. The cleaning liquid adhering to the outer surfaces of the nozzle 51 and the bidet cleaning nozzle 52 is also washed away.

  In addition, when the cleaning water flows through one of the two nozzles 53 and 54 that do not expand and contract, a part of the cleaning water flows into only one of the two nozzles 51 and 52 that expand and contract, and the two nozzles 53 that do not expand and contract. , 54, the position of the discharge port 24 and the arrangement of the O-ring 26 are arranged so that a part of the cleaning water flows only into the other of the two expanding and contracting nozzles 51, 52 when the cleaning water is allowed to flow through the other. For example, at the time of rinsing after flowing the cleaning liquid to the buttocks cleaning nozzle 51, cleaning water is sent to the nozzle cleaning nozzle 54, a part of the cleaning water is supplied to the buttocks cleaning nozzle 51, and the cleaning liquid is flowed to the bidet cleaning nozzle 52. At the time of subsequent rinsing, cleaning water may be sent to the toilet cleaning nozzle 53 and a part thereof may be supplied to the bidet cleaning nozzle 52. In this case, the flow rate of the cleaning water sent to each of the nozzles 51 and 52 can be maintained appropriately, and when the cleaning liquid is supplied to the buttocks cleaning nozzle 51 or the bidet cleaning nozzle 52, the cleaning liquid turns to the other side. Disappears.

  Further, when supplying the cleaning water for rinsing after flowing the cleaning liquid, the control circuit C energizes the heater H, and the temperature is higher than the temperature at which the user can select the temperature of the cleaning water ( It is also preferable to supply cleaning water (for example, 45 ° C.) for rinsing. The washing liquid can be washed away more reliably.
