BACKGROUND OF THE INVENTION
The present invention relates to a device for supplying cleaning water or the like to a warm water cleaning toilet seat, and more particularly to a pressurizing device for a warm water cleaning toilet seat that pressurizes cleaning water from a water source and supplies it to the warm water cleaning toilet seat.
[0002]
[Prior art]
In a normal warm water cleaning toilet seat, a water source port and a warm water cleaning toilet seat are directly connected by a pipe or the like, and cleaning water is supplied to the warm water cleaning toilet seat by water pressure from the water source. However, in places where the water pressure from a water source such as a high place is low, sufficient washing water is not supplied to the warm water washing toilet seat, so a pressure device such as a pressure pump is provided between the water source port and the warm water washing toilet seat. Pressurize the wash water and supply the wash water to the warm water toilet seat.
[0003]
A control configuration of a conventional warm water washing toilet seat pressurizing apparatus will be described with reference to FIG.

The control means 58 is connected to a connection connector 62, and the connection connector 62 is connected to an electromagnetic valve 57 by an electric wire 60 and a pressurizing pump 55 by an electric wire 61, and is electrically connected.
[0006]
In the pressurizing device for the warm water flush toilet seat having the above-described configuration, in the initial state, the pressurizing pump 55 is stopped and the electromagnetic valve 57 is closed. When the toilet user presses a shower switch (charm switch) (not shown) of the operation section main body 59 to perform cleaning, a voltage is applied from the control means 58 to the electromagnetic valve 57, and the electromagnetic valve 57 is opened.
[0007]
At the same time, a voltage is applied to the pump 55, and the pump 55 starts to operate. For this reason, the wash water from the water source port 51 is pressurized by the pressurizing pump 55 and sent to the hot water tank 52 through the check valve 56, the electromagnetic valve 57, and the flow rate adjusting mechanism 63. At this time, the electromagnetic valve 66 (electromagnetic valve 67) located upstream of the shower nozzle 64 (charm nozzle 65) is also opened. For this reason, the wash water in the hot water tank heated by the hot water heater 68 is ejected from the shower nozzle 64 (charm nozzle 65) through the electromagnetic valve 66 (electromagnetic valve 67). When the toilet user presses a stop switch (not shown) of the operation unit main body 59, no voltage is applied from the control means 58 to the electromagnetic valve 57 and the pressurizing pump 55, and the pressurizing pump 55 stops operating. The electromagnetic valve 57 is closed, the water source 51 and the hot water tank 52 are shut off, and the supply of cleaning water is stopped.
[0008]
[Problems to be solved by the invention]
In the pressurizing device for the warm water cleaning toilet seat having the above-described configuration, the operation unit main body 59, the control means 58, the connection connector 62, and the electromagnetic valve 57 are in the hot water cleaning device 50. On the other hand, the pressurization pump 55 is located outside the hot water cleaning apparatus 50. For this reason, since the electric wire 61 which connects the pressurizing pump 55 and the connection connector 62 becomes a wiring from the outside to the inside of the hot water cleaning device 50, the wiring in the hot water cleaning device 50 becomes complicated, and the wiring is troublesome. Take it. Further, since there are various connection connectors 62 depending on the model, compatibility must be considered depending on the model. Furthermore, as shown in FIG. 4, since the electric wire 61 is wired from the outside to the inside of the hot water cleaning device 50, the electric wire 61 itself is exposed to the outside, and the appearance is deteriorated.
[0009]
Therefore, the present invention makes the electric wiring between the operation unit main body and the toilet main body simple, can be applied immediately without considering the compatibility of the connection connector depending on the model, and has a good appearance in the hot water washing toilet seat Therefore, it is a technical subject to provide a pressurizing device.

[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0015]
FIG. 1 is a diagram showing a control configuration of a hot water cleaning apparatus according to the present invention.
[0016]
In FIG. 1, washing water from a water source port 1 is fed into a hot water washing device 9 by a pipe 8 having a branch plug 2, a pressure pump 3, a flow rate sensor 4, a check valve 5, a solenoid valve 6, and a flow rate adjusting mechanism 7. Is sent to a hot water tank 10 provided in The other end branched by the branch plug 2 is connected to the low tank 11. The pressure pump 3 is electrically connected to the flow rate sensor 4 via the pressure pump control means 12. The solenoid valve 6 is electrically connected to the solenoid valve control means 13, and the solenoid valve control means 13 is also electrically connected to the main body operation unit 14.
[0017]
Next, the operation of the pressurizing device 15 for the warm water flush toilet seat having the above configuration will be described.
[0018]
(1) At the start of hot water washing When a toilet user presses a shower switch (charm switch) (not shown) provided in the main body operation unit 14, an electric signal is transmitted to the electromagnetic valve control means 13. Then, a voltage is applied from the solenoid valve control means 13 to the solenoid valve 6. For this reason, the solenoid valve 6 is opened. When the solenoid valve 6 is opened, the pressure inside the pipe 8 is released, so that the cleaning water in the pipe 8 moves slightly. A slight movement of the washing water in the pipe 8 is detected by the flow rate sensor 4, and the detected amount is converted into a flow rate and transmitted to the pressure pump control means 12. The pressurizing pump control means 12 constantly monitors the flow rate from the flow rate sensor 4 and applies a voltage to the pressurizing pump 3 when the flow rate becomes a predetermined value or more. This predetermined value is set to a value equal to or lower than the flow velocity detected by the flow velocity sensor 4 when the electromagnetic valve 6 is opened when the pressurizing pump 3 is not driven. Then, since the flow velocity input to the pressurization pump control means 12 exceeds a predetermined value by opening the electromagnetic valve 6, a voltage is applied from the pressurization pump control means 12 to the pressurization pump 3, and the pressurization pump 3 Is driven.
[0019]
Therefore, the wash water is pressurized by the pressurizing pump 3 and supplied to the hot water tank 10 through the flow rate sensor 4, the check valve 5, the electromagnetic valve 6, and the flow rate adjusting mechanism 7. At this time, the electromagnetic valve 18 (electromagnetic valve 19) provided upstream of the shower nozzle 16 (charm nozzle 17) is also opened. Therefore, the wash water heated by the hot water heater 19 in the hot water tank 10 is ejected from the shower nozzle 16 (charm nozzle 17) through the electromagnetic valve 18 (electromagnetic valve 19).
[0020]
{Circle around (2)} When the toilet user uses a stop switch provided in the main body operation unit 14 when the hot water washing is stopped, an electric signal is transmitted to the electromagnetic valve control means 13. Then, no voltage is applied from the electromagnetic valve control means 13 to the electromagnetic valve 6. For this reason, the solenoid valve 6 is closed. When the electromagnetic valve 6 is closed, the water channel in the pipe 8 is closed, so that the washing water does not flow in the pipe 8 and the flow velocity detected by the flow velocity sensor 4 is rapidly reduced. When the flow rate is equal to or lower than the predetermined value, no voltage is applied from the pressure pump control means 12 to the pressure pump 3. For this reason, the drive of the pressurizing pump 3 is stopped, and the supply of the washing water to the hot water tank 10 is stopped.
[0021]
FIG. 2 is an operation diagram of each part showing the above operation. In FIG. 2, when the shower switch is turned on, the electromagnetic valve 6 is opened. When the electromagnetic valve 6 is opened, the flow velocity detected by the flow velocity sensor 4 increases. When the flow rate is equal to or higher than the predetermined value, the pressurizing pump 3 is turned on. Further, when the stop switch is turned on, the electromagnetic valve 6 is closed. When the electromagnetic valve 6 is closed, the flow velocity detected by the flow velocity sensor 4 drops rapidly. When the flow velocity is equal to or lower than the predetermined value, the pressurizing pump 3 is turned off.
[0022]
Comparing FIG. 1 showing the control configuration of the present invention with FIG. 3 showing the conventional control configuration, in the prior art, an electric wire 61 connected to the inside from the outside (pressure pump) of the hot water cleaning device, and It can be seen that the one corresponding to the connection connector 62 is not necessary in the present invention. For this reason, wiring inside the hot water cleaning apparatus is simplified. Further, since there is no need for a connection connector as in the prior art, there is no need to consider compatibility of the connection connector depending on the model. Furthermore, in the present invention, since there is no electric wire exposed to the outside, the appearance of the appearance is improved.
[0023]
In this embodiment, the flow rate sensor is used as a means for detecting the movement of the fluid in the pipe. However, the present invention is not limited to this, and the movement of the fluid such as a flow rate sensor can be detected. Anything is applicable.
[0024]
【The invention's effect】
The invention of claim 1 has the following effects.
[0025]
Since fluid operation detection means is provided in the middle of the pipe connecting the water source port and the warm water washing toilet seat, and the pressurization device is driven and stopped according to the detection state of the fluid operation detection means, the hot water washing device main body and the outside are Therefore, the wiring can be simplified, the time required for wiring can be shortened, and the appearance can be improved. Further, since the conventional connection connector is not used, it is not necessary to consider the compatibility of the connection connector depending on the model, and the wiring can be performed in a proper manner.
[0026]
The invention of claim 2 has the following effects.
[0027]
Since the operation of the pressurizing device is started when the fluid motion detecting means detects the motion of the fluid above the predetermined value, and the operation of the pressurizing device is stopped when the motion of the fluid below the predetermined value is detected, It is possible to prevent malfunction of the pressurizing device due to vibration or the like.
[0028]
The invention of claim 3 has the following effects.
[0029]
