Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a hot water flushing device for a toilet that cleans the buttocks of a person, and more specifically, a jetting nozzle that jets flushing water is cleaned in advance before use. The present invention relates to a hot water flushing device for toilets that has a function that allows for.

<Conventional technology> As a hot water flushing device for toilets, for example,
A device described in Japanese Patent No.-58674 has been proposed. The configuration of this device will be explained with reference to FIG. 1
2 is a jet nozzle for spouting cleansing water toward the buttocks, and 2 is a hot water tank. Water from the water supply 3 and the like enters the device via the on-off valve 4, passes through the flow control valve 5, and flows to the switching valve 6 side and the relief valve 7 side. The switching valve 6 and the relief valve 7 are each opened by the pressure of the water being sent. The water that has passed through the switching valve 6 is sent to the hot water tank 2, and is jetted out from the jet nozzle 1 as cleaning hot water. Further, the water that has passed through the relief valve 7 is sent out to a drain passage 8.

<Problems to be Solved by the Invention> One of the problems in the toilet hot water cleaning device is the problem of cleaning the jet nozzle 1 itself. This cleaning of the jet nozzle 1 is preferably performed before the cleaning water is jetted from the jet nozzle 1 toward the body.

However, in the case of the above-mentioned conventional device, the jet nozzle 1 is cleaned by water sent to the drain passage 8 through the relief valve 7, but in this conventional device, when the on-off valve 4 is opened, At the same time, the flow rate control valve 5, the switching valve 6, the hot water tank 2
Water pressure is applied to the jet nozzle 1 via the jet nozzle 1. Therefore, the jet nozzle 1 advances to a predetermined jetting position and starts jetting at the same time as water pressure is applied. That is, the conventional device has a drawback in that the jet nozzle 1 cannot be sufficiently cleaned by the water flowing into the drain passage 8 in its standby position, ie, the retracted position.

<Purpose> Therefore, the present invention solves the drawbacks of the above-mentioned prior art,
To provide a system that can sufficiently wash a spouting nozzle by using a part of the water sent into a hot water washing device for a toilet before the spouting nozzle advances and starts spouting, thereby providing a more sanitary system. The purpose is to provide hot water flushing equipment for toilets.

<Means for Solving the Problems> The present invention is provided at the tip of the main waterway 21 in the device and advances to a predetermined position within the toilet bowl by the water pressure of the flushing water that passes through the main waterway 21. a hot water heating tank 15 located upstream of the jet nozzle 13 for sending water at an appropriate temperature to the jet nozzle 13; 13
a water force regulator 16 for adjusting the force of water gushing out from the main waterway 2;
1, a nozzle cleaning channel 20 provided separately from the main water channel 21 for pre-cleaning the jet nozzle 13 in the retreated position, and a nozzle cleaning channel 20 located upstream of the water pressure regulator 16. hand,
The water that is first sent from the main on-off valve 19 side through the main waterway 21 is sent to the nozzle cleaning waterway 20 for a short period of time, and then delayed to the water flow regulator 1.
A hot water flushing device for a toilet, which is equipped with a delay mechanism 17 for sending water to the water pressure regulator 1 side.
Reference numeral 6 has a relatively large resistance to introducing water into the water pressure regulator 16, and the delay mechanism 17 has a water channel 6 branched from the main water channel 21 leading to the water pressure regulator 16 side and connected to the nozzle cleaning water channel 20. and a spring 5 in the direction of always opening the connecting passage.
6. A valve body 53 is provided which is energized and advances against the spring 56 to close the connection passage when water pressure of a certain level or more lower than the water introduction resistance of the water force regulator 16 is applied. It is characterized by the presence of

<Function> The water initially sent from the water source by the opening operation of the main on-off valve 19 flows through the main channel 21 of the delay mechanism 17.
The water tries to flow to the water force regulator 16 side through the
Since the water introduction resistance of the water force regulator 16 is large, the water cannot flow to the water force regulator 16 side (that is, it does not flow to the jet nozzle 13 side). On the other hand, since the pressure of the first water sent to the connection passage branching from the main waterway 21 to the nozzle cleaning waterway 20 is still small, the valve body 53 cannot be advanced against the spring 56. As a result, the connection passage to the nozzle cleaning channel 20 is kept open. Therefore, the water sent first is delayed by the delay mechanism 17.
The water is sent to the nozzle cleaning channel 20 through the connecting passage, and the jet nozzles 13 that have not yet advanced are cleaned by water pressure. Then, the water pressure gradually increases due to the water sent from the water source, so after a while after the opening/closing valve 19 is opened, the water pressure applied to the valve body 53 reaches a certain level or more, and the spring 56 is attached. As a result, the valve body 53 advances against the biasing force of the spring 56, and the nozzle cleaning channel 20
Close the connecting passage to. As a result, the flow of water into the nozzle cleaning channel 20 is stopped, and cleaning of the jet nozzle 13 is completed. After that, the water pressure in the main channel 21 further increases due to the water sent from the water source, so that the water pressure exceeds the water introduction resistance of the water pressure regulator 16, and the water is no longer introduced to the water pressure regulator 16 side. The process is started, water is supplied to the jet nozzle 13, the jet nozzle 13 advances, and water is jetted out.

<Example> FIG. 1 is an overall configuration diagram of an implementation apparatus according to the present invention,
FIG. 2 is a sectional view showing a specific example of the delay mechanism.

Water from a water source such as a city water supply passes through a branch faucet 11 and enters a hot water flushing device 12 for a toilet according to the present invention. Water is also branched from the branch faucet 11 to the low tank of the toilet. Toilet hot water cleaning device 1
2 is provided with a hot water jet nozzle 13, an air charge mechanism 14, a hot water heating tank 15, a water force regulator 16, a delay mechanism 17, a constant pressure governor 18, and a main on-off valve 19. The hot water jetting nozzle 13 jets hot water upward to wash the buttocks of a person, and when water pressure is applied, it advances to a predetermined spouting position of a toilet bowl (not shown) and starts jetting, so it becomes a plunger type. ing. The air charge mechanism 14 allows air to enter the waterway to the jet nozzle 13 when the jet nozzle 13 is not in use,
By preventing water from remaining in the water channel in a continuous manner, it is possible to prevent bacteria and the like that entered from the jet nozzle 13 from entering the water source side such as a water supply. The hot water heating tank 15 is used to heat water to a predetermined temperature selected within the tank, store the water, and send water at an appropriate temperature to the jet nozzle 13. The water force regulator 16 is connected to the jet nozzle 13
This is to adjust the force of hot water spouted from the nozzle cleaning channel 20.
The water is drained to the side and the remainder is sent to the hot water heating tank 15. The water flow regulator 16 divides the total amount of water sent to a preset desired ratio,
It itself has a fairly high resistance to water. The delay mechanism 17 does not send the water initially sent by the opening operation of the main on-off valve 19 to the water force regulator 16 as it is, but flows it to the nozzle washing channel 20 side for a while, and then This mechanism allows the water to flow to the water force regulator 16 at the same time. The constant pressure governor 18 reduces the pressure of high pressure water sent from a water source such as a tap water source to an appropriate water pressure. The main on-off valve 19 is used when a toilet user cleans the toilet.
By opening the main on-off valve 19, water is charged to the hot water heating tank 15 via the water pressure regulator 16, and at the same time, the jet nozzle 13 is advanced by water pressure to jet hot water. The nozzle cleaning channel 20 directs water sent from the delay mechanism 17 to the jet nozzle 13 in the retreated position.
the jet nozzle 1 in the retracted position.
It serves as a waterway for performing the cleaning described in step 3, and also as a drain passage for draining the water sent as unnecessary water from the water pressure regulator 16 into the toilet bowl. The above-mentioned on-off valve 19, constant pressure governor 1
8. The delay mechanism 17, the water pressure regulator 16, the hot water heating tank 15, and the air charge mechanism 14 are arranged in series from the branch faucet 11 side on the main water channel 21 that guides the cleaning water from the branch faucet 11 to the jet nozzle 13. has been done.

One specific example of the delay mechanism 17 will be explained with reference to FIG. 2. The delay mechanism 17 is constituted as one block, and a cylindrical space 52 is formed inside surrounded by an outer wall 51, and a piston-shaped valve body 53 is disposed within the space 52.
A valve seat 57 is provided on the inner wall of the space 52 in correspondence with the above. The space 52 has a water inlet 54 from the main waterway 21 going from the constant pressure governor 18 to the water force regulator 16, and a water inlet 54 from the space 52 to the nozzle cleaning waterway 20.
A water outlet 55 is provided for discharging water to the tank. The piston-shaped valve body 53 is formed in a cylindrical shape, and water flows through the inner hole 53a to the water inlet 5.
4 to a water outlet 55. The water inlet 54, the inner hole 53a, the space 52, and the water outlet 55 constitute a connecting passage from the main water channel 21 to the nozzle cleaning channel 20. Further, the valve body 53 is always urged in the direction of the water inlet 54 by a spring 56, and when no water pressure is applied from the water inlet 54 side, the valve body 53 is not allowed to retreat in the direction of the water inlet 54. in the state where the tip of the cylindrical valve body 53 is separated from the valve seat 57 provided on the inner wall of the space 52, and the opening of the tip of the inner hole 53a of the valve body 53 is opened, the result,
A connecting passage from the water inlet 54 to the water outlet 55 communicates with each other (right half of Figure 2). On the other hand, the water inlet 54
When the water pressure applied to the valve body 53 from the side increases beyond a certain level and exceeds the force of the spring 56, the valve body 53 is advanced by the water pressure, and as a result, the tip of the valve body 53 moves into the space 52. The opening at the tip of the inner hole 53a of the valve body 53 is thereby closed, and as a result, the connection passage from the water inlet 54 to the water outlet 55 is blocked. (left half of Figure 2). As mentioned above, the water force regulator 16 itself has a large water introduction resistance against water flow, or is made to have a large water introduction resistance, and therefore, when the main on-off valve 19 is opened, the water that initially flows through the main waterway 21 is Since the water pressure is low, the water cannot flow to the water pressure regulator 16, but instead tries to flow from the main waterway 21 to the water inlet 54 side. Since the water pressure at this time is still lower than the constant water pressure required for the valve body 53 to advance against the spring 56, the connection passage within the delay mechanism 17 is maintained in an open state, and as a result, the water flows into the nozzle cleaning channel 20. Then, as the water pressure gradually increases, the valve body 5
The water pressure applied to 3 becomes equal to or higher than a certain water pressure, whereby the valve body 53 advances against the biasing force of the spring 56.
The connection passage within the delay mechanism 17 is closed,
The flow of water into the nozzle cleaning channel 20 is stopped.
Thereafter, when the water pressure further exceeds the water introduction resistance of the water force regulator 16, water starts flowing into the water force regulator 16.

The water guided from the delay mechanism 17 to the nozzle cleaning channel 20 flows through the jet nozzle 13 which is still in the retracted position.
Wash. After a short period of time, the water will flow to the water pressure regulator 1.
6, water pressure is applied to the jet nozzle 13 via the hot water heating tank 15, and the jet nozzle 1
3 advances to a predetermined position and starts spouting cleaning water.

<Effects> The present invention has the above configuration, and the water force regulator 16
has a relatively large resistance to introducing water into the water pressure regulator 16, and the delay mechanism 17 includes a connection passage branching from the main water channel 21 leading to the water pressure regulator 16 side and connecting to the nozzle cleaning water channel 20. , the spring 56 is biased in the direction of always opening the connection passage, and water pressure of a certain level or more lower than the water introduction resistance of the water force regulator 16 is applied, so that the connection passage is advanced against the spring 56 and the connection is opened. Valve body 5 that closes the passage
3, the water that is initially sent by the opening operation of the main on-off valve 19 is reliably sent to the nozzle cleaning channel 20 without being sent to the spout nozzle 13 side by using water pressure changes. Therefore, the jet nozzle 13 can be reliably cleaned before it advances and starts jetting water. Furthermore, by further changes in the water pressure thereafter, cleaning of the jet nozzle 13 can be automatically stopped, and the advancing of the jet nozzle 13 and the jetting of water can be automatically started.

Of course, according to the present invention, the above-mentioned effects can be achieved with simple parts and configuration by effectively utilizing the rising change in water pressure accompanying the start of water supply, without using changes in water temperature or the like.
