Abstract

PURPOSE:To save the time of hot water supply operation and prevent the waste of the hot water due to the failure to insert a drain water plug by providing the drain water plug with a solenoid value which operates in conjunction with water and hot water supply sources via a controller and which is closed when the water and hot water supply sources are actuated. CONSTITUTION:When a button for water and hot water supply on a control pannel 17 is depressed, a solenoid valve 11 kept open to clean a bathtub 1 of soils and drain out the waste water is closed and, at the same time, a solenoid valve 7 is opened to supply a hot water from a hot water pipe 9 into the bathtub 1. When the hot water reaches a predetermined water level, it is detected by a water level sensor 19, a controller 15 is activated and the solenoid valve 7 is closed to stop the hot water supply. By such an automation, the water and hot water supply operation can be performed easily by a labor-saving remote control from outside the bathroom without the operator going frequently to a bathroom to check to see if a drain hole 5 is closed or a proper water level is reached. Also, this method eliminates the probability of wasting the hot water due to an inadvertent failure to close the drain hole 5 as used to happen.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a bathtub system with an automatic drain closing mechanism.

(Prior art) When filling a bathtub with water or hot water, conventionally, the first step is to go to the bathroom, plug the drain plug into the drain port at the bottom of the bathtub, and then pour water or hot water from the water tap or hot water tap installed in the bathroom. I poured it out and kept it in the bathtub. Similarly, when an automatic hot water supply type water heater is used to supply water or hot water to a bathtub, the drain plug of the bathtub must first be closed before supplying water or hot water.

(Problem to be solved by the invention) However, it is time-consuming to plug the drain plug into the drain port of the bathtub every time you fill the bathtub with water or hot water, and if you forget to plug the drain plug, you may waste water or hot water. There are many things to do.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a bathtub equipped with a water supply, a hot water supply source, and a drain plug, in which the drain plug is connected to a solenoid valve that is linked to the water supply and hot water source via a controller. This solenoid valve is configured to close when the water supply or hot water supply source is activated.

(Function) According to the above means, when filling hot water in a bathtub, when the controller that controls the water supply, hot water supply source, and drain valve is operated, the drain valve of the bathtub is first closed, and then the water supply source or the hot water source is discharged from the bathtub. Water or hot water is poured and accumulates.

(Example) Next, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a system configuration diagram showing a first embodiment of the present invention.

A bathtub 1 is provided with a hot water mixing faucet 3 and a drain port 5. The hot water mixing faucet 3 is connected to a hot water pipe 9 provided with a solenoid valve 7, and the drain port 5 is connected to a drain pipe 13 provided with a solenoid valve 11.
It is connected to the. Each electromagnetic valve 7 and 11 is connected to an operation panel 17 via a controller 15. Further, the bathtub 1 is provided with a water level sensor 19 and a water level gauge 21.
It is connected to the controller 15 via. As described above, a bathtub system with an automatic drainage port closing mechanism is constructed.

According to this bathtub system with an automatic drain closing mechanism, when the water supply/hot water supply button on the operation panel 17 is pressed, a dirty bathtub 1
The solenoid valve 11, which had been open for cleaning and drainage, was closed.
At the same time, the solenoid valve 7 opens and hot water is poured into the bathtub 1 from the hot water pipe 9. After a while, when the water level reaches a predetermined level, the water level sensor 19 detects it, the controller 15 operates, and the solenoid valve 7 is activated.
is closed and hot water supply stops. In this way, automation allows you to visit the bathroom many times to close the drain 5, but you can easily do this by remote control from outside the bathroom without having to check whether the water level is appropriate or not. Water/hot water supply work can be carried out. Furthermore, there is no longer a need to inadvertently forget to close the drain port 5 and waste hot water as in the past.

Note that the water level gauge 21 is for visual observation from outside the bathroom, and may be omitted.

FIG. 2 shows a second embodiment of the invention. It should be noted that the same parts as in the first embodiment are given the same numbers and their explanation will be omitted.

Here, an automatic hot water supply type water heater 51 is connected to a hot water mixer faucet 55 of a sink 53 in a kitchen or the like and to the bathtub 1 via hot water pipes 57 and 59. This water heater 51 is connected to the controller 15. According to this system,
When you press the drain button and hot water supply button on the water heater 51 at the same time,
First, the electromagnetic valve 11 of the bathtub 1 is opened and dirty hot water is drained.

When the drainage is completed, the solenoid valve 11 is closed, and at the same time hot water is supplied from the water heater 51 to the bathtub 1. If a water level sensor is installed here, everything can be done automatically until the hot water supply is completed.

Note that when the water heater 51 is not supplying hot water to the bathtub 1, it can supply hot water to a sink 53 in the kitchen or the like (it can also be used at the same time, but naturally the hot water force will be weaker and it will take time to supply hot water to both sides).

(Effects of the Invention) As described in detail above, according to the present invention, hot water can be supplied to the hot water bath by remote control through automation, thereby saving the labor of hot water supply work. Also, it is possible to prevent wastage of hot water due to forgetting to plug in the drain plug, etc.
