  Further, according to claim 3, a venturi part as a washing water generating part can be easily formed in the handle, and the detergent can be sucked into the venturi part from the detergent passage and mixed with water. The automatic generation of cleaning water in which water and detergent are mixed can be ensured.

  Further, according to the fourth aspect, the washing water detergent generated in the venturi section can be bubbled by adding the vent hole, while the supply of water is stopped by siphon action when the water supply is stopped. Occurrence of the situation where the detergent flows out from the washing nozzle can be avoided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
FIG. 1 shows a first embodiment in which a bathtub is a cleaning target and the lid with a cleaning mechanism of the present invention is applied to the bathtub lid. Reference numeral 2 is a bathtub as a cleaning target, and 3 is a pair of lids with a cleaning mechanism. 1 set of folding-type bathtub lids, 4 is a handle constituting a part of an opening / closing operation part provided on the surface (upper surface in a closed state described later) 310 of the first lid member 31 constituting the bathtub lid 3, 5 Is a cleaning nozzle provided on the back surface (lower surface in a closed state described later) 313 of the first lid member 31.

  The bathtub lid 3 has a first end 311 that is swingably connected around a horizontal axis X to an end member 30 that is installed on an end of one side of the bathtub 2 (side adjacent to the wall of the bathroom). Foldable from the lid member 31 and a second lid member 32 in which one end edge 321 is hingedly connected to an axis parallel to the horizontal axis X with respect to the other end edge 312 of the first lid member 31. It is configured. As shown in FIG. 1 (a), the bathtub lid 3 grips the handle 4 from the closed state over the top opening 22 (see FIG. 1 (b)) of the bathtub 2, and holds the first lid member 31. The other end edge 312 side is lifted upward and the first lid member 31 is swung around the horizontal axis X to undulate with the hinge-coupled second lid member 32, and finally FIG. ), The first and second lid members 31 and 32 are overlapped and turned upside down so that the upper surface opening 22 is opened. In this open state, the back surface (bottom surface in the closed state) 313 of the first lid member 31 is superposed on the back surface of the second lid member 32.

  The handle 4 is provided on the surface 310 in the vicinity of the other end edge 312 of the first lid member 31. More specifically, as shown in FIG. 2, the handle 4 has a gate-like handle shape in which a pair of leg portions 41, 41 rising from the surface 310 are gripped between the upper ends of the leg portions 41 and 41, and a bridging portion 42 is bridged. It is formed. The first lid member 31 including the handle 4 has a water supply passage 6 for supplying water toward the washing nozzle 5 and a venturi as a washing water generating unit interposed in the water supply passage 6. A part 7, a detergent storage tank 8 for introducing detergent to the venturi part 7, and a vent hole 9 for introducing air to the venturi part 7 are also provided.

  The water supply passage 6 is connected to an upstream end (for example, reference numeral 61 in FIG. 1A) of a water supply source or a hot water supply source (not shown) (for example, a hot water supply pipe from a water heater, or such a hot water supply pipe). When a solenoid valve (not shown) is opened by an ON operation of a cleaning switch (for example, reference numeral 10 in FIG. 1A), a back pressure (for example, supply of a water pipe) is connected. In response to the pressure), water of a predetermined flow rate or more is made to flow toward the washing nozzle 5 which is the downstream end. The water supply passage 6 extends, for example, from the upstream end 61 to the inside of the end member 30, and then communicates from the one end edge 311 to the inside of the first lid member 31 to extend inside the first lid member 31 to extend the handle 4 in FIG. 2. The one side leg portion 41, the gripping collar portion 42, and the other side leg portion 41 are communicated with the cleaning nozzle 5.

  When the cleaning switch 10 is turned ON, the ON signal is output to a controller (not shown). The controller outputs an open signal to the solenoid valve, and the opening / closing control of the solenoid valve is performed according to a predetermined cleaning operation program ( For example, the operation is performed according to a cleaning operation control in which opening and closing are intermittently repeated and spraying and waiting of cleaning water are repeated. At that time, a flow rate adjusting valve or a flow rate sensor is provided at a predetermined position of the water supply passage 6 to control operation of the flow rate adjusting valve by the controller, or the detected value of the flow rate sensor is used for this operation control. Alternatively, control may be performed so that the flow rate of water or hot water flowing when the solenoid valve is opened is reliably set to a predetermined flow rate.

  The venturi portion 7 is provided in the grip collar portion 42 of the handle 4, and a flow path (flow path) between the upstream water supply passage portion 63 and the downstream water supply passage portion 64 with the venturi portion 7 interposed therebetween. The inner diameter is changed to be narrow so that the cross-sectional area) is narrowed, and the flow rate of water passing therethrough is increased by narrowing the flow of water. Then, the solenoid valve is opened and a predetermined flow rate of water or hot water (hereinafter referred to as “hot water”) is supplied from a water supply source or the like, thereby increasing the passage flow rate of the water and reducing the flow rate on the upstream and downstream sides. A predetermined negative pressure region lower than the atmospheric pressure is formed by lowering the pressure than the passage portions 63 and 64. In the negative pressure region in the venturi section 7, the downstream end 82 (see FIG. 2A) of the detergent passage 81 opens toward the negative pressure region, while the upstream end 83 of the detergent passage 81 has a detergent storage. It extends so as to open at a position near the bottom surface of the tank 8. Further, as shown in FIG. 2 (a), one end 91 of the vent hole 9 is opened in the venturi portion 7 so as to face the negative pressure region, and the other end 92 is opened to communicate with the atmosphere. Yes.

  The detergent storage tank 8 is formed by denting a predetermined volume in a state where the upper surface of the surface 310 at the lower position of the handle 4 is open to the atmosphere. The volume of the detergent storage tank 8 is set so as to correspond to the maximum amount of detergent required for one cleaning, and the above-mentioned maximum amount is used as the detergent for each cleaning by the user for each cleaning. In the range up to, a desired amount is introduced. The first lid member 31 in which the water supply passage 6 and the venturi portion 7 and the like are formed is formed by synthetic resin molding using, for example, a pipe line in which the water supply passage 6 and the venturi portion 7 are formed as an insert material. You can do it.

  After the user takes a bath with the bathtub lid 3 opened, the washing operation can be performed with the remaining hot water discharged from the bathtub 2, and the user puts the detergent into the detergent storage tank 8 to perform the automatic washing operation. Then, when the above-described cleaning switch 10 is turned on, cleaning is performed as follows. That is, when the solenoid valve is opened by turning on the cleaning switch 10, hot water from a water supply source or the like is caused to flow through the water supply passage 6 to the venturi portion 7, and the flow rate is increased when passing through the venturi portion 7, resulting in negative pressure. Form a region. Thereby, the detergent in the detergent storage tank 8 is sucked into the negative pressure region through the detergent passage 81 and mixed with hot water to generate washing water, while air is also sucked into the negative pressure region from the vent hole 9 at the same time. Will cause the cleaning water detergent to be foamed. Then, the foamed cleaning water is sprayed from the cleaning nozzle 5 toward the inner surface 23 (see FIG. 1C) of the bathtub 2 to be cleaned. In addition, as a structure of the washing nozzle 5, you may employ | adopt an injection nozzle or a spray nozzle other than a spray nozzle.

When the above-described intermittent cleaning operation control is implemented in the controller as a cleaning operation program, the electromagnetic valve is opened for cleaning for a predetermined time corresponding to the use of a predetermined amount (for example, about 3 cc) of detergent. Spraying of the washing water from the nozzle 5 is performed, the electromagnetic valve is closed by the lapse of a predetermined time, and the spraying is stopped, and the standby state is waited for the predetermined time. Then, after waiting for a predetermined time, the spraying of the washing water and the standby in the stopped state are repeated a predetermined number of times. Then, when the detergent in the detergent storage tank 8 is exhausted, only hot water is supplied through the opened electromagnetic valve to perform rinsing for a predetermined time, and the electromagnetic valve is closed after the lapse of time. When the solenoid valve is closed and the flow of hot water is interrupted, the cleaning water or hot water in the venturi portion 7 or in the downstream water supply passage portion 64 is washed by the air flowing into the venturi portion 7 from the vent hole 9. On the other hand, the detergent in the detergent passage 81 is returned to the detergent storage tank 8 by gravity drop. Therefore, the occurrence of a situation in which the detergent in the detergent storage tank 8 flows out of the cleaning nozzle 5 due to the siphon action over the detergent passage 81, the venturi portion 7, the downstream water supply passage portion 64, and the cleaning nozzle 5 is avoided. Can do.

  The opening position (82) of the detergent passage 81 with respect to the negative pressure area of the venturi section 7 and the opening position (91) of the vent hole 9 are the negative pressure area formed in the venturi section 7 when hot water passes through. There is no circumstance that either must be upstream or downstream. Accordingly, in FIG. 2 (a), the opening position (91) of the vent hole 9 is shown on the upstream side, but conversely, it may be set downstream of the opening position (82) of the detergent passage 81.
