Abstract

PURPOSE:To prevent inflow of hot-water from a bathtub into a bath boiler, eliminate heat dissipating loss from the bath boiler, prevent temperature decrease of hot-water during using the bathtub and facilitate follow-on heating by a method wherein the notched opening of a cover is arranged so as to rub the slat of a rotating piece. CONSTITUTION:When hot-water is poured into the bathtub 4 by the hot-water supplier 1 through a hot-water supplying cock 2, a knob 16 is turned until the pin 15 thereof is abutted against a stopper 17 so that the notched opening of the cover 11 rubs the slat 13 of the rotating piece 12 to prevent inflow of water into the bathtub 4 through a suction connecting pipe 5, the bath boiler 3 and a push-out connecting pipe 6, and eliminate the heat dissipating loss from the bath boiler 3 to prevent the reduction of hot-water temperature during using the bathtub 4 while the water in the bathtub flows into the bath boiler 3 by opening a watehe elastic section 11 to the side of the blow-off port 3 while the tip ends of the first and second legs 12, 13 are provided with engaging parts 14, 15 respectively. Respective engaging partning of the cover 11 and the foloow-on heating may be effected by the bath boiler 3 through the operation of a water level switch when the follow-on heating is necessary.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is applied in the field of bath colon system, by closing the water circulation path to the first bath pot when hot water is poured into the bathtub. This relates to a device that eliminates heat radiation loss and saves energy in the bathtub area.

Conventional configuration and its problems In conventional bath hot water supply systems, the water circulation path to the bath pot is open during hot water supply and curing, so when the bathtub is used, there is a lot of heat radiation loss from the bath pot, and the bathtub's gh l! ,, it is not a device that can prevent the drop of t as much as possible.

OBJECTS OF THE INVENTION Accordingly, the present invention solves the above-mentioned conventional drawbacks.
When dropping into a bathtub using a stop-start type water heater, operate the knob until it hits the stopper so that the notch opening of the cover rubs against the vane of the rotor, and hot water from inside the bathtub flows into the bathtub. Prevent water from flowing in, eliminate heat loss from the bathtub, and use the bathtub 11! In addition to preventing the water temperature from dropping in J, when refilling, it is linked to the 1 manual switch and the water from the bathtub to the bath kettle (
By opening the water switch connected to the suction connection pipe, the water in the bathtub flows into the bath pot, and this water pressure acts on the rotor's guide plate, causing the rotor's vane plate to move from 1 to 1 of the cover. It is said to be a ``noh'' that automatically moves to the extent that it slides into the IJ notch and closes, and easily brings a normal bathtub without any operation.

Structure of the Invention The present invention provides a bath hot water supply system consisting of a stop-start type water heater, a straight suction connection pipe that passes through the bathtub with a flange portion left inside the bathtub, and a bath pot that is directly connected to the extrusion connection pipe and has a built-in water level switch. A water switch that branches off from the middle of the suction connection pipe, is connected in series to a manual switch, and is directly connected to a straight pipe that fits in the bathtub at the same height as the suction connection pipe, and a cylinder with a hole in the center. a cover having a cap shape, a cylindrical tip bent to be attached to the flange portion of the suction connection pipe and the extrusion pipe, and having opening and closing openings at equal intervals on the cylindrical surface; Insert between the suction connection pipe and the flange part of the extrusion connection pipe 9J for opening the cover 011
In order to seal the cracks, there are arc-shaped blade plates equidistant from the cover, a spiral guide plate extending from the blade plate toward the center, and an O (1) with a knob in the center that can be operated from the hole in the cover. In order to properly open and close the rotor, the cover, and the blade plate (i9), two stoppers are provided on the cover, one of which is in contact with the knob.

Arc-shaped blade plates 13 with an interval of 0 degrees, and spiral-shaped guide plates 14 with the same bending angle from the blade plates 13 toward the center.
and a bottle 15 at the tip that can be operated from the hole in the cover 11.
It is a rotor consisting of a longitudinal knob 16 in which a rotor is embedded. 17i8 is the cover 11 so that the cover 11 and the 111 closing of the blade plate 13 can rub well together and the bottle 15 can come into contact with the cover 11.
These are stoppers A and B provided at the

In the above configuration, when dropping hot water from the hot water faucet 2 into the bathtub 4 using the stop-start type water heater 1, the bottle 15 of the knob 16 is moved to the stopper Ai7 so that the notch opening of the cover 11 rubs against the rotor 120 and the vane plate 13. Operate until it hits the suction connection pipe 5. ~Bath pot 3~Prevents hot water from flowing into the bathtub 4 from the push-out connection vibro, eliminates heat radiation loss from the bath pot 3, and prevents a drop in water quality when the bathtub 4 is in use.

JhIAIF acts, and the blade plate 13 of the rotor 12 rubs against the 9-notch closing part of the cover 11, and the screw knob 16 is turned.
The bottle 15 moves automatically when it touches the stopper B18, and the water level switch 7 is operated to easily bring about the pressure of the bathtub 3 without any operation.

Effects of the Invention When dropping into a bathtub using a stop-start type water heater, operate the knob until it hits the stopper so that the 9 notches in the cover rub against the blades of the rotor, and then drop the water into the bathtub into the bathtub. Prevent hot water from flowing in, eliminate heat radiation loss from the bathtub, and use the old 1. In addition to preventing the +1 hot water 1711i from dropping, it is also possible to open the water gate closing device connected to the suction 1γ connection pipe from the bathtub to the M8 pot in conjunction with the manual switch (! : The water in the bathtub flows from the bath pot to the extrusion connecting pipe ~ 6 tanks, and this water pressure acts on the guide plate of the rotor, automatically until the blade plate of the rotor slides into the notch closing part of the cover. Because it moves, it is a hot water supply system device that can easily bring hot water to the bathroom without any operations.

Claims (1)

[Scope of Claims] A stop-start water heater and a bathtub with a built-in water level switch that is directly connected to a straight suction connection pipe and an extrusion connection pipe that pass through the tank, leaving a flange inside the bathtub (Iiii) , a water switching device branched from the middle of the suction connection pipe, connected in series to the manual switch, and directly connected to the straight pipe that fits in the bathtub at the same height as the rJ sales connection pipe, and a hole in the center. IIX (
'J cylindrical light': 1i has a bent shape and a cover with opening/closing notches at equal intervals in circles 911TII, and flanges of the molded connection pipe and extruded connection pipe in the front cover. An arcuate blade plate is spaced equally apart from the cover so that the l/j notch in the cover can be sealed, and a knob is provided that allows the blade plate to be moved from the blade plate toward the center. A rotor with a rotor in the center, and two stoppers provided on the cover so that the opening and closing of the cover blade plate can be smoothly rubbed together and come into contact with the knob, the IFFFF on-site formal water heater is installed in the bathtub. When dropping the bathtub, operate the lever described in +il'I until it hits the stopper so that the notch opening of the cover rubs against the vane plate of the rotor, thereby eliminating heat radiation loss from the bathtub. At the same time, at the time of recharging, the water opening/closing device is opened in conjunction with the manual switch, and the water pressure extracted from the suction and extrusion connecting pipe acts on the guide plate of the rotor and automatically starts the rotation. The bath water heater was in trouble because the slats of the slats moved as if they were sliding against the missing cover cover, and the IJ'J water level switch was used to warm the bath normally.
