Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a heat insulating structure for a nozzle in a toilet bowl with a local cleaning device.

(Prior art and its problem) Conventionally, in a toilet bowl with a local cleaning device, a nozzle that can be inserted into and removed from a cylinder is provided in order to eject hot water to the local area of a toilet user to clean it after use. It has a structure where hot water adjusted to an appropriate temperature is jetted from a nozzle in a hot water tank. However, in the initial stage of ejecting the washing water from the nozzle, the cold water remaining in the nozzle may be ejected to the toilet user, which causes a problem of causing discomfort to the toilet user. In this, in order to eliminate the cold water jetted from the nozzle in this initial stage and jet hot water of an appropriate temperature from the beginning, the residual water in the nozzle is drained or
Alternatively, a method has been adopted in which the area around the nozzle is heated by a heater to heat the residual water in the nozzle.

In the structure for removing the residual water from the nozzle, water is wastefully discharged, which is not preferable, and in the structure in which the heater is arranged in the peripheral portion of the nozzle, water droplets or the like may enter the heater. However, there is a problem that the risk of electric shock increases and that a device for controlling the heater is required.

(Means for Solving the Problems) The present invention has been devised in view of the above-mentioned conventional problems, and provides a nozzle heat retaining structure capable of ejecting warm water of an appropriate temperature from the nozzle from the initial stage with a safe and simple structure. The purpose of the present invention is to install a local cleaning device, which is equipped with a nozzle that is capable of ejecting hot water to the local area of a user and a hot water tank that stores hot water to be supplied to the nozzle. In the toilet bowl, a heat retaining water storage portion communicating with the hot water tank is provided around the outer periphery of the cylinder.

(Function) By providing a heat retaining water storage part that communicates with the hot water tank around the outside of the cylinder containing the nozzle, warm water heated to an appropriate temperature in the hot water tank flows into the heat retaining water storage part by natural convection. Thus, the outer circumference of the cylinder can be warmed with this hot water, and the warm water in the cylinder warms the residual water remaining in the nozzle. Therefore, the residual water in the nozzle is kept at an appropriate temperature, and the washing water ejected from the nozzle becomes an appropriate temperature from the initial stage, so that cold water is not ejected in the initial stage as in the conventional case, and the user is inconvenient. No pleasant sensation.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The figure shows a side cross-sectional configuration diagram of a toilet bowl with a local cleaning device. In the figure, a toilet seat 2 is installed on the upper surface side of the toilet body 1 so as to be openable and closable, and a toilet lid 3 is installed above it so as to be openable and closable. Has been done. Further, a low tank 4 is erected on the rear upper surface side of the toilet body 1, and in the low tank 4, a floatable ball valve 5 capable of flowing flushing water into the toilet body 1 is arranged. A ball tap 7 having a float 6 for keeping the water level at a constant value is provided. A bellows pipe 8 is connected to the ball tap 7 in a hanging shape, and a connecting pipe 9 is connected to a lower end portion of the bellows pipe 8.

The connecting pipe 9 is provided outside the bottom surface of the raw tank 4 and is connected to the rear surface of the toilet body 1. Inside the connecting pipe 9, an air vent pipe 10 and a water flow pipe 11 forming an air passage 10a.
Is installed inside, and the lower end of the air bleeder 10 is the toilet body 1
It is connected to an air pipe 25 arranged inside.

A hot water tank 12 is provided on the rear bottom surface side in the toilet body 1, and the air pipe 25 is connected to an air port 12a of the hot water tank 12. Also, hot water tank 1
A heater 13 for heating water is provided in the inside of the unit 2, and a temperature sensor 14 for controlling the water temperature in the hot water tank to an appropriate temperature is provided near the heater 13.
Further, an outflow pipe 15 is vertically installed in the warm water tank 12, and an upper end portion of the outflow pipe 15 serves as an outflow port 15a.
An upstream pipe 16 is connected to the outlet 15a, and an electromagnetic pump 17 is connected to the upper end of the upstream pipe 16. Further, the electromagnetic pump 17 has a downstream pipe 1
8 is connected, a branch pipe 19 branched from the downstream pipe 18 is connected to a cylinder 20 provided on the upper rear surface side of the toilet body 1, and communicates with a cylinder water passage 20a formed in the cylinder 20. Has become. Further, the tip end of the downstream pipe 18 is connected to a position where it can communicate with the nozzle water passage 21a of the nozzle 21 that is internally installed so as to be able to move in and out of the cylinder 20.

In this example, the heat retaining water storage portion 22 is provided in an encircling manner on the outer periphery of the lower surface side and the side surface side of the cylinder 20, and the heat retaining water storage portion 22 is disposed between the wall surface of the heat retaining water storage portion 22 and the outer wall surface of the cylinder 20. A path 22a is formed. This warm water reservoir 2
The inflow pipe 23 is connected to the inflow pipe 2
3 is connected to the inflow pipe 11 inside the toilet body 1. Further, a connection pipe 24 formed by winding a heat insulation cover 24a around the outer periphery is connected to the heat retention water storage part 22, and a lower end portion of the connection pipe 24 is a circulation port 12b formed on the upper surface side of the hot water tank 12. It is connected to the.

In such a configuration, tap water introduced into the raw tank 4 from the external water pipe via the ball tap 7 is
The tap water is introduced into the inflow pipe 23 through the bellows pipe 8 and the inflow pipe 11, and the introduced tap water is introduced into the hot water tank 12 from the connecting pipe 24 through the heat retaining path 22a. The tap water introduced into the warm water tank 12 is heated by the heater 13 and becomes warm water. For example, when the shower switch is turned on while the toilet user is sitting on the toilet seat 2, the electromagnetic pump 17
Is turned on and the hot water in the hot water tank 12 is pressurized from the outflow pipe 15 through the upstream pipe 16 by the electromagnetic pump 17,
It is introduced from the downstream pipe 18 through the branch pipe 19 into the cylinder water passage 20a. The pressure water introduced into the cylinder water passage 20a presses the nozzle 21 forward,
A nozzle 21 is projected from the cylinder 20 to the front side of the toilet body 1. When the nozzle 21 is projected, the downstream pipe 1
8 and the nozzle water passage 21a communicate with each other, and the downstream pipe 18
As a result, the pressurized water flows into the nozzle water passage 21a, and the pressurized water is ejected from the ejection port at the tip of the nozzle 21 to the local area of the user as washing water.

When the electromagnetic pump 17 is not operating, the nozzle 21 is stored in the cylinder 20 due to the action of the spring or the like, but residual water naturally remains in the nozzle water passage 21a.

In this example, the warm water reservoir 22 is formed around the outside of the cylinder 20, and the warm water reservoir 22 is connected to the connection pipe 24. Therefore, the warm water tank 12 is heated to an appropriate temperature. The collected water is introduced into the heat retaining water storage section 22 by natural convection through the connecting pipe 24, and the heat retaining path 22
The warm water circulates while rising in a, and the warm water keeps the outer circumference of the cylinder 20 warm. Therefore, as the cylinder 20 is kept warm, the water remaining in the nozzle water passage 21a is also kept warm. Therefore, when the electromagnetic pump 17 is turned on, the residual water in the nozzle water passage 21a is kept at an appropriate temperature even when the nozzle 21 is projected and the residual water in the nozzle water passage 21a is ejected from the nozzle 21. Unlike the conventional case, cold water is not jetted, and warm water having an appropriate temperature is jetted to the local area of the user from the initial stage.

The air vent pipe 10 is for discharging the air in the hot water tank 12 into the low tank 4 through the air port 12a when fresh water flows into the hot water tank 12 through the circulation port 12b. This is to improve the inflow of fresh water.

As described above, in this embodiment, the warm water storage portion 22 is provided on the outer peripheral portion of the cylinder 20 that constitutes the local cleaning device, and the warm water in the warm water tank 12 is introduced into the warm water storage portion 22 by natural convection. With a simple structure, the residual water in the nozzle water passage 21a can be well kept warm,
There is no need to keep the residual water warm by using a heater or the like as in the past.

(Effect of the device) The nozzle warming structure of the toilet bowl with a local cleaning device of the present invention is provided with a warming water storage part communicating with the warm water tank on the outer periphery of the cylinder, so that the warm water in the warm water tank is kept warm by natural convection It is introduced into the water storage section to keep the outer circumference of the cylinder warm,
