Description

[Detailed description of the invention] The present invention relates to a steam pressure circulating bath pot that can perform forced circulation heating without the need for an electric pump etc. by heating a heater and using the pressure of steam generated inside the heater. The purpose of this method is to utilize the force of water vapor to send the remaining hot water in the bathtub to the washing machine, thereby making effective use of the remaining hot water.

Hereinafter, embodiments of the present invention will be described based on the drawings. 1 is a bathtub; 2 is an inflow channel 3 connected to the bathtub 1;
5 is a check valve installed in the inflow path 3, and 6 is a ventilator installed in the outflow path 4, which also serves as a resistor. One end of the bypass passage 7 is branched from the inflow passage 3, and the other end of the bypass passage 7 is opened. 8 is the outflow path 4
A two-way switching tap provided on the downstream side of the ventilate 6 branches a hot water supply path 9 from the switching tap 8, and the hot water supply path 9 is led to a washing machine 10. In addition, when the switching tap 8 is provided upstream of the vent turret 6, the same vent turret 6 and bypass channel 7 are provided on the hot water supply path 9 side as well. 11 is a burner that heats the heater 2;

The present invention has such a configuration, and in order to heat the bathtub water, when the switch valve 8 is switched to the bathtub 1 side and the burner 11 is ignited, steam is generated in the heater 2 and the internal pressure of the heater increases. However, on the inflow side, as the internal pressure of the heater increases, the check valve 5 changes from open to closed, so the pressure is released to the outflow side, and at this time, the hot water heated in the heater 2 is transferred from the outflow path 4 to the bathtub 1. Push it out. When the hot water in the heater 2 is discharged, the internal pressure of the heater rapidly decreases, and the check valve 5
is opened, cold water from the bathtub 1 is newly sucked into the heater 2 from the inflow path 3, and steam is generated by heating again, and the cycle is repeated to heat up the bath.

Next, if you want to use the hot water left in the bath for washing, just switch the switching tap 8 to the hot water supply path 9 side and ignite the burner 11. As in the case of bath heating, the remaining hot water is reheated by the steam pressure generated in the heater 2 and is then transferred from the hot water supply path 9 to the washing machine 1.
It is sent to 0.

In either case of bath heating circulation or hot water supply, cold water is mixed with the pumped hot water from the bypass passage 7 by the suction action of the ventilate 6 and is discharged at a moderate temperature, so there is no risk of burns.

As described above, in the present invention, the hot water supply path leading from the circulation path of the bath pot to the washing machine is branched, and the circulation path and the hot water supply path are switched by a switching tap. By using the force of the steam generated, the remaining hot water from the bath can be pumped into the washing machine without using a pump, which is extremely convenient.
