Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water temperature stabilizing device for stabilizing the temperature of hot water sent from a water heater and a mobile bathing vehicle equipped with the same.

[0002]

2. Description of the Related Art A mobile bathing vehicle used for a mobile bathing service or the like includes a water tank for storing water for bathing,
A water heater for heating the water in the water storage tank for bathing,
A pump for transporting the hot water generated by the water heater to the bathtub is mounted.

[0003] Conventionally, as a water heater used for a mobile bathing vehicle, an instant heating type water heater equipped with a heat exchanger using a heater using kerosene or the like as a fuel has been used.

Generally, in an instantaneous heating type water heater provided with a combustion chamber such as a heater, when a hot water supply curan is opened and hot water supply is started, the heater is burned and hot water heated in the heat exchanger is removed. The water is supplied to the outside through the hot water supply curan. Then, when the hot water supply is terminated by closing the hot water supply curran, the combustion of the heater is also stopped.

Here, the control of the heater is performed based on a control signal from a flow rate sensor for measuring the flow rate of water flowing inside the water heater. More specifically, when the amount of water flowing inside the water heater exceeds a specified value, the heater is ignited by a signal from the flow sensor and the water in the heat exchanger is heated. I have. Further, when the amount of water flowing in the heat exchanger falls below the specified value, the heater is extinguished by a signal from the flow rate sensor.

[0006] It is difficult for the heater used in such an instantaneously heated water heater to instantaneously control the heating power at the time of ignition. Also, if the amount of water supplied during heating and hot water supply is limited to a small amount, the heater tries to maintain the minimum controllable amount of heat that can be operated, so that a small amount of water flowing inside the heat exchanger of the water heater becomes unnecessary. It may be heated and become higher than the set temperature. Further, when the water supplied to the water heater is completely shut off by closing the hot water supply curran, the residual heat of the heat exchanger may heat the water stored in the pipe to a temperature higher than a set temperature.

For this reason, high-temperature hot water may be instantaneously supplied from the water heater. However, in conventional moving bathing vehicles, the temperature of the high-temperature water supplied instantaneously from the water heater is stabilized. Means is not provided.

[0008]

As described above, in the instant heating type hot water heater, although high-temperature hot water may be supplied immediately after ignition, a conventional moving bathing vehicle does not have a hot water heater. No means is provided for stabilizing the hot water temperature.

Therefore, in order to use hot water supplied by the instantaneously heated water heater for bathing service, after opening the hot water supply curl and igniting the heater, the hot water of the heater is stabilized while discharging hot water for a while. I have to wait.

[0010] In addition, if hot water instantaneously supplied from a water heater is erroneously used for a bathing service, an accident such as a burn of a bather may occur.

The present invention has been made in view of the above problems, and has a simple structure and a hot water temperature stabilizing apparatus capable of safely supplying hot water supplied from a water heater at a relatively stable temperature, and a moving apparatus using the same. The purpose is to provide a bathing car.
