Definitions

  • This disclosure generally relates to a sanitary washing apparatus for washing a human private part.
  • sanitary washing apparatuses There are two major types of known sanitary washing apparatuses provided at a warm water washing toilet seat and discharging warm water to wash a human private part in view of a method of supplying washing water.
  • One of the two types refers to the sanitary washing apparatus where water that is supplied from a public water supply is heated directly (that is, without using a pump) and then used for washing.
  • a water pressure of the public water supply is used as-is as a water pressure of the washing water.
  • the other one of the two types refers to the sanitary washing apparatus where the water supplied from the public water supply is obtained via the pump, heated and then used as the washing water.
  • the water supplied from the public water supply is stored at a water storage tank once, and the water stored at the water storage tank is pumped up by the pump and then used.
  • the water pressure is applied by the pump to the washing water.
  • the sanitary washing apparatus where the pump is applied is suitably used.
  • the known sanitary washing apparatus As disclosed in JPS59-102030A and JPH3-20386Y (which are hereinafter referred to as Patent reference 1 and Patent reference 2, respectively), the known sanitary washing apparatus, where the pump is used for obtaining the water from the supply water source, includes a control circuit and/or a controller for controlling the pump.
  • the sanitary washing apparatus connected directly to the water supply is not provided with the pump for obtaining the water from the supply water source, and therefore the aforementioned control circuit and/or the controller for controlling the pump do not need to be provided. Accordingly, in order to manufacture the known sanitary washing apparatus where the pump for obtaining the water from the supply water source is used, a control circuit and/or a controller need to be configured and arranged so as to be completely different from those of the sanitary washing apparatus which is connected directly to the water supply.
  • a control means 51 controlling an opening/closing operation of an electromagnetic valve 48 via a first solid state relay (SSR) 50 additionally includes a function for controlling an operation of a pump motor 42a of a pump 42.
  • SSR solid state relay
  • control means 51 is connected via a second solid state relay (SSR) 44 which is supplied with electric power from a power supply 49 and is connected, for example, to the pump motor 42a.
  • a water flow control portion 47 which includes the electromagnetic valve 48 and the first SSR 50, is commonly provided at the sanitary washing apparatus where the pump 42 is not used and at the sanitary washing apparatus where the pump 42 is used.
  • an upstream side of a water flow path relative to the electromagnetic valve 48 is connected directly to the public water supply without the pump 42 interposed between the public water supply and the electromagnetic valve 48.
  • a water pressure of water outputted from the pump 42 is adjusted by adjusting voltage of the pump motor 42a by means of a voltage adjustment circuit 46 for adjusting voltage of a driving power supply.
  • a second control means 144 may be provided at a sanitary washing apparatus 141 independently from the first control means 51 controlling the electromagnetic valve 48 (the first control means 51 corresponds to the control means 51 in Fig. 5A ).
  • the function of the control means of the sanitary washing apparatus that does not include the pump 42 needs to be modified to a large extent or the independent control means needs to be arranged.
  • the control means for each of the types needs to be designed and manufactured independently from each other. This may result in an increase in manufacturing costs and an increase in the number of manufacturing processes.
  • a sanitary washing apparatus includes a pump for delivering a washing water to a water flow route to which the washing water flows, an electromagnetic valve interposed between a supply water source and the pump, and allowing the washing water to be supplied from the supply water source, a control means for controlling the electromagnetic valve to open/close, and a switching circuit provided with a switching element, the switching circuit links an opening/closing operation of the electromagnetic valve and an operation/operation stop of the pump to each other without an interposition of the control means, the switching circuit operates the pump when the electromagnetic valve is in an open state in which the electromagnetic valve supplies the washing water and stops the pump when the electromagnetic valve is in a closed state in which the electromagnetic valve blocks supply of the washing water.
  • an electric system and a water flow path of the electromagnetic valve, and an electric system and a water flow path of the pump are linked to or associated with each other by means of a function or an operation of the switching circuit that is provided with the switching element.
  • the electromagnetic valve is commonly provided also at a type of the sanitary washing apparatus which is not provided with the pump and which is connected directly to the supply water source such as a public water system.
  • the sanitary washing apparatus which has the above-described structure at which the pump is provided, is configured on the basis of a configuration of a type of the sanitary washing apparatus, which is not provided with the pump and which is connected directly to the supply water source, there is no need that the control means controlling the electromagnetic valve controls also the pump and there is no need to provide an independent control means that exclusively controls the pump.
  • the sanitary washing apparatus provided with the pump may be configured without modifying the control means or increasing a number of the control means.
  • the electromagnetic valve includes an opening/closing electric circuit where the electromagnetic valve is in the open state when the electromagnetic valve is electrified and the electromagnetic valve is in the closed state when the electromagnetic valve is not electrified
  • the switching element includes a relay
  • the relay includes an input terminal that is parallelly connected to the opening/closing electric circuit of the electromagnetic valve and an output terminal that is serially inserted in an intermediate portion of a driving power supply circuit of the pump, and an electric power from a driving power supply is supplied to the pump when the electromagnetic valve is in the open state by the opening/closing electric circuit and supply of the electric power to the pump is interrupted when the electromagnetic valve is in the closed state by the opening/closing electric circuit.

  • the driving power supply circuit of the pump includes a voltage adjustment circuit configured to adjust an electric voltage supplied to the pump.
  • a power supply for opening/closing the electromagnetic valve is commonly used for the driving power supply to the pump.
  • a power supply for driving the pump is supplied via an AC adapter from a commercial power supply.

  • the SSR 10 is connected to the control means 11 so that an opening/closing operation of the electromagnetic valve 8 is controlled via the SSR 10 by the control means 11.
  • the SSR 10 disconnects the electric current supply circuit so as to maintain the electromagnetic valve 8 in the closes state.
  • a weak electric current is inputted from the control means 11 to the SSR 10, and the electric current supply circuit is connected via the SSR 10, that is, the electric current supply circuit is established. That is, the electric current is supplied from the power supply 9 to the electromagnetic valve 8, the electromagnetic valve 8 comes to be in the open state and the washing water is actually supplied to the water flow route R.
  • the control means 11 is implemented by a microcomputer (a micon), for example.

  • the voltage adjustment circuit 6 that is inserted in an intermediate portion of a power supply circuit to the pump motor 2a will be explained.
  • the pump motor 2a that is commercially available includes a large variation in an output thereof among individuals, which causes variation in the water pressure of the washing water supplied via the electromagnetic valve 8 to the water flow route R. This causes variation in the water pressure of water supplied from the water flow route R to a user of the sanitary washing apparatus.
  • the sanitary washing apparatus is provided with the washing means where the water flow route R includes the nozzle which discharges the warm water and which is configured to be extended by the water pressure of the washing water to an operable position, the nozzle may not be extended sufficiently if the water pressure of the washing water is too low.
