Next, the operation will be described. Bathroom heating and drying devices have several modes of operation. Ventilation operation,
The operation is performed when the steam in the bathroom 1 is drained depending on the level of ventilation. There are two types of heating operation: pre-bathing heating and bathing heating. In pre-bathing heating, the circulation fan 4 heats and circulates the air in the bathroom 1 with a sheath heater before bathing, and preliminarily heats the bathroom 1. When the inside temperature is not low, the bath heating is performed by radiant heating by the quartz heater 5, and since the circulation fan 4 is not operated, the heating can be performed without a feeling of cool wind due to the airflow.

[0007] Further, in the clothes drying, the sheath heater is operated to heat the air from the circulation fan 4 to generate warm air, and the clothes are dried by using both the circulation operation of the warm air and the ventilation operation. In the air drying, the clothes are dried by operating both the circulation fan 4 and the ventilation operation without operating the quartz heater 5. In the bathroom drying, the entire bathroom 1 is dried by a combination of the circulation operation of hot air and the ventilation.

Next, each operation mode will be described in detail. First, the ventilation operation will be described with reference to FIGS. The ventilation SW11 is operated to set the level of ventilation, and the off timer SW19 is operated to set the timer remaining time (0.5 to 12 hours) (S1401). Therefore, when the ventilation weakness is set, the weak driving is started,
The weak ventilation LED 12a is turned on (S1402). After that, driving continued until the remaining time timer expired,
Alternatively, if the stop SW 10 is operated (S1403), the ventilation weak LED 12a blinks, and the delayed operation of the ventilation fan is performed for a maximum of 2 minutes 30 seconds (S1404).
The ED is turned off and the operation is stopped (S1405).

On the other hand, if the strong ventilation is set at S1401, the strong operation of the ventilation fan is started and the strong ventilation LED is set.
12b is turned on (S1406). After that, the operation continued until the remaining time timer expired, or the stop SW

Proceed to and, similarly to the above, blink the ventilation strong LED 12a,
Delayed operation of the ventilation fan is performed for a maximum of 2 minutes and 30 seconds (S140
4) Then, all the LEDs are turned off and the operation is stopped (S
1405).

Next, the heating operation will be described with reference to FIGS. 9 to 13 and FIG. Before bathing, the heating SW 13 is operated (pressing the heating SW 13 once), heating before bathing is set, and the off timer SW 19 is operated to set the timer remaining time (0.5 to 12 hours) ( S15
01). Thereby, the circulation fan 4 is strongly operated, the air in the bathroom 1 is sucked from the intake port 7, heated by the sheath heater, and the warm air is blown out into the bathroom 1 from the air supply port 8, thereby discharging the air in the bathroom. Heating and heating are performed, and the pre-bathing heating LED 14a is turned on (S1502).

Thereafter, the operation is continued until the remaining time timer expires, or the stop SW 10 is operated (S
1503) In the case, the pre-bathing heating LED 14a blinks, the sheath heater is immediately turned off, and the circulation fan 4 is turned on for a certain period of time (2 minutes 20 seconds to 2 hours) until the sheath heater temperature decreases.
30 minutes), the operation is delayed (S1504), and all the LEs are operated.
D is turned off and the operation is stopped (S1505). Thus, the heating before bathing performs warm air heating by the circulation fan 4 and the sheathed heater.

Further, when taking a bath, the heating SW 13 is operated again (pressing the heating SW 13 twice), the bathing heating is set, and the cut-off timer SW 19 is operated so that the timer remaining time (0.5 to 12 hours). Is set (S15
01). As a result, the quartz heater 5 is turned on, the radiant heat is radiated from the air supply port 8 to the space inside the bathroom 1, heating without a sense of airflow is continued, and the bathing heating LED 14b is turned on (S1506).

Thereafter, the operation is continued until the remaining time timer expires, or the stop SW 10 is operated (S
1507) In the case, the pre-bathing heating LED 14a blinks, the quartz heater 5 is immediately turned off, and the circulation fan 4 is operated for a fixed time (2 minutes 20 seconds to 2 minutes 30 seconds) until the temperature of the quartz heater 5 decreases. (S1504), and turns off all the LEDs and stops the operation (S1504).
5). As described above, the bath heating performs radiant heating by the quartz heater 5.

Next, the bathroom drying operation will be described with reference to FIGS.
3. Description will be made with reference to FIG. The bathroom drying SW 17 is operated to set the bathroom drying, and the cut-off timer SW 19
Is operated to set the timer remaining time (0.5 to 12 hours) (S1601). As a result, the circulation fan 4 is strongly operated, the air in the bathroom 1 is sucked from the intake port 7 and heated by the sheath heater, and the air in the bathroom is heated by blowing warm air from the air supply port 8 into the bathroom 1. While heating the bathroom, turning on the bathroom drying LED 18, and strongly operating the ventilation fan to draw in the air in the bathroom from the air inlet 7 and exhaust the air to the outside. Flows into the bathroom 1 from the waste (S1602).

Thereafter, when the operation is continued until the remaining time timer expires or the stop SW 10 is operated (S1603), the bathroom drying LED 18 flashes, the sheath heater is immediately turned off, and the sheath heater temperature decreases. The circulation fan 4 for a certain period of time (2 minutes 20 seconds to 2
30 minutes), the operation is delayed (S1604), and all the LEs are operated.
D is turned off and the operation is stopped (S1605). In addition, since the clothes drying is not directly related to the present invention described later, the detailed description is omitted.

[0016]

In the conventional heating and drying apparatus as described above, it is necessary to operate the heating SW 13 and the cut-off timer SW 19 again immediately before actually bathing from the pre-bathing heating. There was a problem. In addition, the remaining time of the timer, that is, the bathing time (0.5 to 12 hours) must be determined before entering the bath. If the actual bathing time becomes longer than the bathing time set in advance, the bathing time is also set. Regardless, the heating stops, so the person has to go to the position of the operation controller installed outside the bathroom and set it again, feeling cold and uncomfortable, and conversely, turning off the timer SW19
If the bathing time (0.5 to 12 hours) is set longer than the actual bathing time, the bathing operation must be stopped by the stop SW 10 if the bathing is completed earlier, and if this operation is forgotten. There is a problem that heating is continued until an unnecessary time and energy is wasted. Further, since the heat capacity of the quartz heater 5 is constant, there is a problem that when a person is in a bathroom tub or in the vicinity of the bathroom heating / drying device 13, it is too hot.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and controls heating operation switching before and during bathing and control of heater capacity according to the presence or absence and position of a person in a bathroom. It is possible to obtain a heating and drying device that can improve comfort and save energy.

Embodiment 3 6 and 7 are flowcharts showing the operation of the heating operation of the heating / drying apparatus according to Embodiment 3 of the present invention. FIG. 6 is an operation flow based on detection of a human body position in a bathtub, and FIG. 7 is heating of a human body position. 4 shows an operation flow based on detection of immediately below or near a drying device, respectively.
In addition, the figure which shows a heating-drying apparatus and its installation situation, the external view of the operation controller of a heating-drying apparatus, and the block diagram of a human body position detection sensor are the same as that of Embodiment 1, and respectively use FIG. In FIG. 1, reference numeral 46 denotes a bathroom temperature detecting sensor, which is an indoor temperature detecting means.

Next, the operation will be described. First, the heating operation based on the detection of the human body position in the bathtub will be described with reference to FIG. The operation of switching from pre-bathing heating to bathing heating (S601 to S603) is performed in S40 of the first embodiment.
This is performed in the same manner as 1 to S403. In bathing and heating, a bathroom temperature detection sensor 46 installed in the bathroom heating and drying device 3
, The bathroom temperature is detected, and the bathroom temperature is compared with a predetermined temperature Ts (S604). The predetermined temperature Ts is, for example, a value between 30 and 35 ° C.

Therefore, when the bathroom temperature is higher than the predetermined temperature Ts, the heater capacity reduction coefficient Kh of the quartz heater 5 is set to 0.5 (S605). When the bathroom temperature is lower than the predetermined temperature Ts, the heater capacity reduction coefficient Kh is set to 1. 0 (S606)
And Thereafter, the human body position detection sensor 20 detects whether the human body position is inside the bathtub (S607). When the human body position is in the bathtub, the heater capacity human body position capacity coefficient Kf is set to be smaller than 1 (for example, 0.7), and the rated capacity W × heater capacity reduction coefficient Kh × heater capacity human body position capacity coefficient Kf is set to the quartz heater. As a heater capacity of 5,
The quartz heater 5 is controlled (S608).

On the other hand, when the human body is not in the bathtub but in a washing room or the like, the quartz heater 5 is controlled by setting the rated capacity W × heater capacity reduction coefficient Kh as the heater capacity of the quartz heater 5 (S609). Thereafter, detection of the completion of bathing, delayed operation, and operation stop (S610 to S612) are performed in the same manner as S404 to S406 in the first embodiment. As a result, when the outside air temperature is relatively high or when a person is in the bathtub, the feeling of being too hot can be eliminated, and the comfort can be improved.
It has the effect of saving energy.

Next, a heating operation based on the detection of a position just below or near the heating / drying device 3 at a human body position will be described with reference to FIG. The operation of switching from pre-bathing heating to bathing heating (S701 to S703) is performed in S40 of the first embodiment.
This is performed in the same manner as 1 to S403. In bathing and heating, the human body position is detected by the
It is detected whether or not it is immediately below or near (S70)
4). If the human body position is directly below or near the heating / drying device 3, the heater capacity of the quartz heater 5 is reduced (for example, 70% of the rated capacity) (S705), and the human body position is directly below or near the heating / drying device 3. If not, the quartz heater 5 is controlled to have the rated capacity (S70).
6). Thereafter, detection of the completion of bathing, delayed operation, operation stop (S
707 to S709) correspond to S404 to S404 in the first embodiment.
This is performed in the same manner as in S404.

As described above, by controlling the capacity of the quartz heater 5 on the basis of the detection of the position of the human body in the bathtub or the detection immediately below or near the heating / drying apparatus, it is possible to prevent the bather from becoming too hot and uncomfortable when taking a bath.

Embodiment 4 FIG. 8 is a flowchart showing the operation of the heating operation of the heating and drying apparatus according to Embodiment 4 of the present invention, and shows the operation flow of the bathroom drying operation after a person leaves the bathroom. In addition, the figure which shows a heating-drying apparatus and its installation state, the external view of the operation controller of a heating-drying apparatus, and the block diagram of a human body position detection sensor are the same as that of Embodiment 1, and respectively use FIG. .

Next, the operation will be described with reference to FIG.
Operation to switch from heating before bathing to bathing heating (S801-
S803) corresponds to S401 to S403 of the first embodiment.
Is performed in the same manner as described above. Thereafter, the bathing is completed by the human body position detection sensor 20, the person leaves the bathroom 1, and it is detected whether or not a human body exists in the bathroom 1 (S804).
Therefore, when the human body position detection sensor 20 detects the exit, the quartz heater 5 is turned off, the circulation fan 4, the ventilation fan, and the sheath heater are turned on, the bathroom drying LED 18 is turned on, and the inside of the bathroom 1 from the intake port 7 is turned on. The air is sucked in, heated by a sheath heater, and heated by blowing warm air from the air supply port 8 into the bathroom 1, thereby heating the bathroom air, heating the ventilation LED 12b, and turning on the ventilation fan. By driving, the air in the bathroom is sucked from the intake port 7 and exhausted outside, and the air corresponding to the exhausted air amount is:
The water flows into the bathroom 1 from the bathroom door rag. Further, the end time of the drying operation, that is, the remaining time of the timer of the cutting timer 19 is set to a standard time, for example, 6 minutes (S8).
05). Thereby, the air in the bathroom is heated and circulated as hot air, and the drying operation in which part of the air in the bathroom is exhausted to the outside is continued, and the bathroom is dried.

When the drying operation time is manually set, the bathroom drying SW 17 is operated (S806), and the off timer SW 19 is operated to set the remaining timer time (S).
807). Thereafter, when the set timer remaining time elapses, the delayed operation and the operation stop (S808 to S809) are performed in the same manner as in S404 to S404 of the first embodiment. In this case, the bathroom drying LED 18 and the strong ventilation LED 1 are used.
After 2b blinks, all the LEDs are turned off. On the other hand, S80
If the drying operation time is not manually set in step 6, the delay operation and the operation stop (S
808-S809) correspond to S404-S of the first embodiment.
404, but in this case bathroom drying LED
18. After the strong ventilation LED 12b blinks, all the LEDs are turned off. In the above description, an example using both the circulation fan 4 and the ventilation fan is shown, but either one may be used.

As described above, in the bathroom drying operation, the standard operation time is automatically set, so that the drying operation can be performed without particularly requiring the SW operation, and when necessary, the operation time can be changed. It is possible to obtain an easy-to-use heating / drying device having flexibility in the time setting.

Embodiment 5 FIG. Embodiments 1, 3 and 4 above
In, at the main steps of the operation to perform notification,
The bather may be able to know that the main step has been performed. For example, in the first embodiment, an operation when performing notification will be described. The description of the operation other than the notification is omitted. First, a notification sound generator, for example, a buzzer or a sound generator (not shown) is installed in the heating and drying device 3. Therefore, when heating before bathing is set by the heating SW13, the alarm sound generator sets "heating before bathing is set."
When the timer remaining time is set to, for example, 6 minutes by the cut-off timer SW19, a sound is generated as "The timer remaining time is set to 6 minutes" (S40).
1). Thereafter, when the person enters the bathroom 1 and the human body is detected by the human body position detection sensor 20, a sound is generated by the notification sound generator, stating that "the human body in the bathroom has been detected and bath heating has been set" (S403).

Next, when the bathing is completed, the person leaves the bathroom 1 and the human body position detection sensor 20 detects that there is no human body in the bathroom 1, "The human body in the bathroom has not been detected. Stop and perform delayed operation. "(S404, S405). When the delayed operation is completed, a sound is generated to indicate that the operation has been completed (S
406). Although the above-described notification sound generator uses a sound generator, the above-described notification sound generation is performed by sounding a buzzer at a main step or changing a sound type of the buzzer according to a difference in operation of the main step. The operation can be grasped in the same way as the container. Also in the third and fourth embodiments, similarly, the notification operation according to the main steps of the first embodiment is performed by a notification sound generator such as a sound or a buzzer to perform notification according to each scene such as ventilation operation. Thereby, the operation can be grasped.

In the first to fifth embodiments, the heating and drying device 3 is provided on the ceiling of a room, which is a bathroom.
