Abstract

PROBLEM TO BE SOLVED: To prevent a scald and burn due to a mist heating apparatus for a bothroom, which requires no dedicated hot water pipe to be arranged between the bathroom and a heat source device. SOLUTION: A hot water feed pipe 19 leading to a mixing tap 20, etc., in a bathroom is branched in the bathroom by using a branching joint 21, and a branching pipe 16 is connected to this branching joint 21 to feed hot water to mist nozzles 3, 7 facing upward and downward. Hot, water mist is ejected from these mist nozzles 3, 7 toward the bathroom and a floor of the bathroom, thereby raising a temperature in the bathroom and on a floor of a wash-place. In this case, a temperature of hot water in the branching pipe 16 is detected by a thermistor 13 and, when the detected results show, for example, 65 deg.C or higher, a three-way valve 14 is closed so as to prohibit high-temperature mist from being ejected.

Next, the operation method of the above embodiment will be described.
First, in the case of the normal mist type heating operation, the three-way valve 14 is switched to the mist nozzles 3 and 7 by the operation switch ON, and the heat source unit (not shown) supplied through the hot water supply pipe 19. Hot water flows from the branch pipe 16 → governor 25 → filter 17 → tap water temperature thermistor 13 (water temperature detecting means) → three-way valve 14 (control valve 30) → unit pipe 12 → upward mist nozzle 3 and downward mist nozzle 7 → Here, it is mist and squirts into the bathroom.

The controller 22 performs the following control in conjunction with the normal operation. 1. The temperature of the water supplied from the branch pipe 16 is determined by the thermistor 13.
When the water temperature detected by the thermistor 13 is equal to or higher than a set water temperature, for example, 65 ° C., the three-way valve 14 or the control valve 30 attached to the branch pipe 16 is controlled to be OFF, and the mist nozzles 3 and 7 Prevent mist from erupting.

2. When the thermistor 13 detects the set water temperature, for example, 65 ° C. or more, the three-way valve 14 or the control valve 3
0 is intermittently turned ON and OFF so that the high-temperature mist is not spouted at once. 3. When the thermistor 13 detects a set water temperature, for example, 65 ° C. or higher, the three-way valve 14 or the control valve 30 is turned on intermittently,
In addition to the OFF control, when the temperature exceeds 70 ° C., for example, the three-way valve 14 or the control valve 30 is closed.

4. The thermistor 13 is set at a set water temperature, for example, 65.
When the temperature is detected to be higher than or equal to ° C., the three-way valve 14 (or the drain valve 31 is opened) switches the high-temperature water to the drain pipe 15 side to drain. 5. While the thermistor 13 detects a safety set water temperature, for example, 65 ° C. or higher, and discharges high-temperature water to the drain pipe 15 side,
° C or less, the hot water is switched to the mist nozzles 3 and 7 side, and the operation is shifted to the heating operation.
If it exceeds 0 seconds, the heating operation is stopped.

6. The water temperature detected by the thermistor 13 detects that the set water temperature is, for example, 65 ° C. or higher, and once closes the three-way valve 14 or the control valve 30. When the water temperature detects 65 ° C. or higher, the heating operation is restarted. 7. When the water temperature detected by the thermistor 13 detects that the set temperature is, for example, 65 ° C. or higher, a warning is issued by driving the warning means 33, and the driving of the warning means 33 is released by turning off the operation stop switch, The operation is restarted by controlling the tap water temperature of the heat source unit to the set water temperature. 8. When the driving of the alarm means 33 exceeds the set time, this driving is stopped. In the embodiment, the set water temperature is 6
Although it is 5 ° C., the set water temperature can be arbitrarily changed and set.

FIG. 3 is a flow chart showing an example of the operation control method, in which the three-way valve 14 or the control valve 30 (operation switch) O
By N (step 100), the thermistor 13 detects 65 ° C. or higher for 3 seconds (step 101), and starts heating operation in the following cases (step 102), and in one or more cases, the three-way valve 14 or the control valve 30 for 7 seconds. Is turned off (step 103), and an error display is output from the alarm means 33 (step 104). If this is repeated 10 times (step 105), the operation is completely stopped (step 1).
06), receiving a remote control stop signal or turning off the built-in timer (Step 107), and in Step 105, the three-way valve 1
4 or the control valve 30 is turned ON for one second (step 10).
8) If a temperature of 65 ° C. or higher is detected (step 109), the flow returns to step 103, and in the following cases, the error is released and the operation shifts to the normal operation (step 110).
