Description

  The present invention relates to a control system of a bathroom heater for heating the inside of a bathroom.

  Especially when the outside temperature is low, such as in winter, if you enter a low temperature bath to bathe, the difference between the room temperature and the room temperature in the bath is large, which is not good for health. Therefore, it is desirable to install a bathroom heater that heats the inside of the bathroom, and to previously warm the room temperature in the bathroom before bathing.

  When setting the heating temperature by this bathroom heater, it was before bathing by heating the room temperature of the kitchen to the same temperature by using the detected temperature of the temperature sensor built into the kitchen remote control and the temperature in the bathroom It is known that there is an attempt to eliminate the difference between the environment and the environment at the time of entering the bathroom (see, for example, Patent Document 1).

JP-A-2004-293847 (paragraph [0017])

  In the above conventional equipment, when heating the bathroom, the room temperature in the bathroom is controlled to be the room temperature of the kitchen, but those who are going to take a bath do not necessarily go from the kitchen to the bathroom, and live outside the kitchen You may go to the bathroom from staying in space.

  At this time, if the room temperature of the kitchen is lower than the room temperature of the living space, you will be bathing in a state where the room temperature in the bathroom is not heated to a sufficient temperature, the merit of installing a bathroom heating device in the bathroom The problem of not being able to take advantage of

  Therefore, in view of the above problems, it is an object of the present invention to provide a control system of a bathroom heating device capable of bringing the room temperature of the bathroom during bathing as close as possible to the environmental temperature at which the bather lasted just before bathing. I assume.

The control system of the bathroom heating apparatus according to the present invention in order to solve the above problems, there is provided a control system for bathroom heating apparatus for heating the temperature of the bathroom to the set temperature, which is installed in the kitchen for controlling the water heater provided with a kitchen temperature sensor for detecting the kitchen room in the kitchen remote control, the upper Symbol set temperature is a target temperature for heating the inside of the bathroom, in what is set based on the detected temperature of the kitchen temperature sensor, the kitchen temperature sensor The detection temperature of the kitchen temperature sensor is continuously detected for a predetermined time, and when the detection temperature of the kitchen temperature sensor continuously detected rises rapidly, the detection temperature of the kitchen temperature sensor before rising and the kitchen temperature sensor after rising The set temperature is calculated from the detected temperature and the inside of the bathroom is heated to the set temperature .

Operating the bathroom heater to heat the bathroom during bathing is when the outdoor temperature is low, such as in winter. In such a case, there is a problem if the room temperature of the bathroom during bathing is low, but there is no problem if the room temperature of the bathroom is too high. Therefore, bather has so by adding and climate of occupied spaces that may have had just before bathing set the set temperature to heat the bath to be the set temperature. However, when the temperature detected by the kitchen temperature sensor is continuously detected for a predetermined time, and the temperature detected by the kitchen temperature sensor that is continuously detected rises sharply, the temperature detected by the kitchen temperature sensor before rising and after the temperature rising The set temperature is calculated from the temperature detected by the kitchen temperature sensor and the interior of the bathroom is heated to the set temperature.

  As is apparent from the above description, the present invention sets the bathroom heating setting temperature not only to the room temperature of the kitchen but also considering the room temperature of the living space, so the environment and the bathroom where the bather was just before bathing A comfortable bathing can be realized by reducing the difference with the internal environment as much as possible.

  Referring to FIG. 1, reference numeral 1 denotes a kitchen, and a living room 2 which is an example of a living space, a bathroom 3 and a dressing room 4 are provided adjacent to the kitchen 1. A water heater 5 is provided outdoors, and a kitchen remote control 11 is provided in the kitchen 1 for adjusting the temperature of the hot water of the water heater 5 and for filling the bath of the bathroom 3 with water. The kitchen remote controller 11 incorporates a kitchen temperature sensor (not shown) for detecting the room temperature of the kitchen 1.

  A hot-water floor heating apparatus 6 is provided in the living room 2, and a living room remote control 21 for controlling the operation of the floor heating apparatus 6 is provided. The living room remote control 21 incorporates a residence temperature sensor (not shown) for detecting the room temperature of the living room 2.

  The bathroom 3 is provided with a bath remote control 31 for adding water to the bathtub and repelling water. Moreover, the bathroom heating apparatus 7 which uses the warm water from the hot-water supply apparatus 5 as a heat source is provided in the ceiling part of this bathroom 3.

  The bathroom heating device 7 can also be controlled by the bath remote controller 31, but a dedicated remote controller 41 is provided in the dressing room 4. The bathroom heating device 7 can be manually started operation by this remote control 41, and when it is set to "automatic" by the remote control 41, for example, when the hot water supply to the bathtub is performed by the kitchen remote control 11, interlocking with the start of water filling The bathroom heater 7 automatically starts operating to start heating the bathroom 3.

  The heating temperature at the time of automatically starting the heating of the bathroom 3 as described above will be described below.

  When the automatic operation of the bathroom heating device 7 is started, the control unit of the hot water supply device 5 detects the temperature detected by the kitchen temperature sensor incorporated in the kitchen remote control 11 and the residence temperature sensor incorporated in the living room remote control 21 of the living room 2 The room temperature of the bathroom 3 is set to be the same as the temperature of the higher one of the room temperature of the kitchen 1 and the room temperature of the living room 2 in comparison with the detected temperature of.

  Here, if the room temperature of the living room 2 is higher than the room temperature of the kitchen 1, as described above, heating may be performed so that the room temperature of the bathroom 3 becomes the same temperature as the room temperature of the living room 2, While heating to a temperature 2 ° C. lower than the room temperature of the living room 2 at the time, controlling the operation of the floor heater 6, heating so that the room temperature of the living room 2 is also 2 ° C. lower than the room temperature at that time The ability may be reduced.

  Thus, if the room temperature of the bathroom 3 is not heated to the same temperature as the room temperature of the living room 2 at that time but set at a temperature 2 ° C. lower, the sense of discomfort when entering the bathroom 3 is almost zero When returning to the living room 2 after bathing, it is relieved that the room temperature of the living room 2 is felt to be higher than necessary. And since the energy consumption amount in the floor-heating apparatus 6 during bathing is suppressed, it is preferable also in energy saving.

  In addition, in the kitchen 1, the room temperature of the kitchen 1 may be temporarily too high, such as when cooking and cooking. Therefore, for example, an upper limit of 30 ° C. is set for the temperature detected by the kitchen temperature sensor of the kitchen remote control 11, and when the temperature detected by the kitchen temperature sensor exceeds the upper limit, the temperature detected by the kitchen temperature sensor The bathroom 3 is heated based on the temperature detected by the residence temperature sensor of the living room remote control 21 without adopting the temperature.

  In addition, when the floor-heating apparatus 6 is not provided in the living room 2, the room temperature of the living room 2 can not be detected directly. Therefore, in such a case, the room temperature of the living room 2 is estimated based on the temperature detected by the kitchen temperature sensor of the kitchen remote control 11.

  Referring to FIG. 2, when the temperature sensor is not installed in the living room 2, in principle, the room temperature of the kitchen detected by the kitchen remote control 11 is used as the room temperature Tf. However, as described above, since the room temperature rises at the time of cooking or the like in the kitchen 1, it is impossible to use the increased temperature as the room temperature Tf of the living room 2. Therefore, the room temperature of the kitchen is continuously detected, for example, every 5 minutes, and the room temperature T1 at point P1 where the room temperature of the kitchen suddenly rises and the room temperature T2 at point P2 where the temperature rise settles, the living room Estimate room temperature Tf of 2. At that time, for example, it is estimated as Tf = 2/3 * (T2-T1) + T1. However, since this coefficient 2/3 may differ depending on the structure of the house, it is desirable to adjust the coefficient for each house to which the present invention is applied. Also, Tf may be estimated by another formula.

  The present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the scope of the present invention.
