Abstract

PURPOSE:To suppress generation of a large quantity of steam in a bathroom and to allow comfortable bathing by controlling a mist temperature to be injected in response to a temperature in the bathroom. CONSTITUTION:When a switch of a mist remote controller 14 in a bathroom 10 is closed, a mist sauna function of a hot water supplying unit 12 is driven, and a controller 17 simultaneously detects a temperature in the bathroom 10 by a temperature sensor 15 in the controller 14, and first so controls an output hot water temperature of the unit 12 side as to atomize mist of a low temperature. As the temperature in the bathroom 10 rises, an output hot water supplying temperature is raised. When the temperature in the bathroom 10 becomes a set temperature, a control of becoming a mist temperature to be felt at a position of a person to bath by a calculation formula of the temperature of the bathroom 10 and a dropping ratio of the mist temperature of a mist nozzle 11' which is previously checked is transferred. The temperature in the bathroom 10 is maintained while turning ON and OFF the operation. Thus, generation of large quantity of steam in the bathroom 10 can be suppressed, and comfortable bathing can be executed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mist type bathroom heating device for heating a bathroom by spraying hot water mist into the bathroom.

[0002]

2. Description of the Related Art A system is known in which hot water mist is jetted into a bathroom for heating. This known example is as shown in FIG.
The hot water generated in the bath water heater 2 with a mist sauna function is guided into the bathroom 1 via the mist hot water supply pipe 3, and the mist shower is jetted into the bathroom 1 from the mist nozzle 5 of the mist unit 4 attached here. Therefore, a mist remote controller 6 is installed in the bathroom 1, and a high temperature mist is jetted at the time of rising, and a temperature sensor 7 in the mist remote controller 6 detects the temperature in the bathroom 3, and when this reaches a set temperature, an intermediate temperature mist is generated. The hot water supply device 2 is stopped via the signal line 8 at the jetting and the set time.

[0003]

As described above, in the conventional mist type bathroom heating device, since the high temperature mist is jetted at the time of rising, the high temperature mist is jetted while the temperature in the bathroom is low. Then, a large amount of steam is generated in the bathroom, and a large amount of condensed water is attached to the ceiling and walls of the bathroom.This not only causes mold, but the sprayed mist directly hits the bather and feels hot or cold. Also, some people may feel uncomfortable.

An object of the present invention is to provide a mist-type bathroom heating device capable of performing heating while suppressing the generation of steam as much as possible and performing comfortable mist heating for a bather.

[0005]

The structure of the mist type bathroom heating apparatus according to the present invention is as follows.

When the bath water heater is provided with a function for controlling the temperature of discharged hot water for mist hot water and the mist heating switch is turned on, the temperature inside the bathroom is detected by the temperature sensor of the mist remote controller installed in the bathroom, and the temperature inside the bathroom is detected. In contrast, the mist hot water temperature that suppresses the amount of steam generated is calculated, and based on this value the hot water temperature control function is controlled and the bather has entered the bathroom or the bath temperature has reached the set temperature. In this case, a mist provided with a control circuit for giving priority to the above-mentioned control so that the mist temperature feels comfortable at the bather's position based on the calculation formula of the bathroom temperature and the mist temperature decrease rate of the mist nozzle investigated in advance. Bathroom heating system.

[0007]

[Function] When the mist remote control switch in the bathroom is turned on, the mist sauna function of the bath water heater is activated, and at the same time, the controller detects the temperature in the bathroom with the temperature sensor in the mist remote control. Since a large amount of steam is generated when the mist of No. 1 is jetted, first, the hot water temperature on the side of the water heater is adjusted so that the mist of a low temperature is jetted. Then, as the temperature rises, the hot water temperature rises, and when the temperature in the bathroom reaches the set temperature, it feels comfortable at the bather's position from the calculation formula of the bath temperature and the mist temperature decrease rate of the mist nozzle that was examined beforehand. The control shifts to the mist temperature. Also, when a bather enters the bathroom during the control, the control is shifted to this control. ON-OFF control is used to maintain the temperature in the bathroom.

[0008]

Embodiments of the present invention will be described with reference to FIG.
In FIG. 1, 10 is a bathroom, 11 is a mist ejector with a mist nozzle 11 ′ mounted in the bathroom 10, 12 is a hot water supply pipe leading to the mist ejector 11, and this hot water supply pipe 12
Is connected to the bath water heater 13 with a mist temperature control function. 14 is a mist remote controller with a temperature sensor 15, 16
Is the remote control line, and this remote control line 16 is the water heater 13.
It is tied to the internal controller 17. The controller 17 performs the following control.

When the operation switch of the mist remote controller 14 in the bathroom 10 is turned on, the water heater 13 is driven and at the same time,
Bathroom 10 with mist remote controller 14 temperature sensor 15
The temperature inside is detected and relative humidity is 100% with respect to this temperature.
The amount of absolute humidity at is calculated, and the air mixed with mist ejected from the nozzle has a relative humidity of 100%.
The mist outlet temperature is calculated so that a certain amount of absolute humidity is added, and the mist temperature control function in the water heater 13 is controlled. The temperature in the bathroom 10 is constantly monitored, and the controller 17 performs the above calculation based on this temperature to control the tap water temperature. However, this control may be performed continuously, or may be performed in three stages. For example, if the mist temperature (outlet temperature) is set to low / medium / high, low temperature mist of around 35 ° C is ejected when rising and the room temperature is as low as 5 ° C, and 45 ° C when rising to around 15 ° C. When the front and rear mists are jetted and the temperature rises to around 25 ° C, a high temperature mist around 55 ° C is jetted to raise the temperature inside the bathroom to the set temperature. ON-OFF control is used to maintain the temperature in the bathroom.

Next, when the temperature in the bathroom reaches the set temperature,
The mist temperature is controlled so that the mist temperature at the bather's position is comfortable according to the calculation formula of the bath temperature and the mist temperature drop rate previously examined. However, this control value is
It is possible to control (correct) the bather's preference. Further, when the bathing person is detected in the bathroom during the control, for example, by the human body detection sensor, the control is prioritized over the control for suppressing the generation of steam, and the control is shifted to this control.

[0011]

As described above, according to the present invention, by automatically controlling the temperature of the mist ejected according to the temperature in the bathroom,
It is possible to suppress the generation of a large amount of steam in the bathroom. As a result, fungus protection can be achieved by reducing the adhesion of dew condensation to the ceiling and walls of the bathroom. Further, by controlling the mist temperature by the calculated value of the temperature decrease rate due to the bathroom temperature which has been investigated in advance, it becomes possible to take a comfortable bath.
