BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for bathrooms and changing rooms.

0002

2. Description of the Related Art Conventionally, this type of air conditioner transfers heat generated by a heat source 1 to air through a heat exchanger 2 and a blower 3.
The piping 4 that transports heat media such as water and fluorocarbons distributes and transports them into each room. Figure 8 shows a bathroom 5 using air as a heat medium.
, which air-conditions the dressing room 6. Temperature detection means 7 and 8 are provided in each room, and based on the output results thereof, the bathroom temperature setting section 9 and the dressing room temperature setting section 10 set the temperature. The bathroom temperature comparison section 11 compares the set temperature and the current temperature of each room.
, a control circuit 14 including an air conditioning control section 13 for controlling the air conditioning, and a control actuator such as a damper 15.

[0003] The air conditioner is operated to maintain a set temperature by controlling the air volume, controlling the capacity of the heat source, and the like.

0004

[Problems to be Solved by the Invention] However, in bathrooms and changing rooms, the conditions on the human body that affect the user's sense of temperature change greatly due to the presence or absence of clothes and the accumulation of heat in the human body during bathing, so the conventional structure described above is not suitable. In a configuration that controls to maintain a constant temperature, the temperature sensation before bathing in the changing room and the temperature sensation after bathing are completely different even if the temperature is the same, and it is difficult to make the changing room comfortable before bathing. Even with this setting, there was a problem that the bath would be too hot or too cold after taking a bath.

[0005] The present invention is intended to solve the above-mentioned problems, and takes into consideration that the temperature sensation of the human body changes due to bathing.
The purpose is to change the air conditioning state by changing the set temperature, etc., and to realize an air conditioning state that corresponds to the change in temperature sensation on the human body side.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a bathroom physical quantity detection means for detecting physical quantities related to the bathroom environment, a timer for measuring the time spent in the bathroom, and a bathroom physical quantity detection means for detecting physical quantities related to the bathroom environment. The changing room air conditioning state determining means controls the air conditioning in the changing room based on the detection result of the detection means and the time measured by the timer.

[0007] Furthermore, human body detection means for detecting the entry of a user into the bathroom is provided instead of the bathroom physical quantity detection means.

[0008]

[Operation] With the above configuration, the present invention detects changes in physical quantities related to the environment, such as temperature and humidity in the bathroom, and determines whether a user has entered the bathroom based on the detection results. At the same time, the time after entering the room is measured, and the air conditioning status of the changing room is changed based on this measured time. This creates a changing room where the user can change the environment of the changing room while taking a bath and feel comfortable when returning to the changing room after bathing. Also, instead of detecting changes in physical quantities related to the environment,
A similar effect can be obtained by directly detecting when a user enters or leaves the bathroom.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

In FIG. 1, air is heated or cooled by a heat source 1 in a heat exchanger 2, and the conditioned air is distributed through a blower 3 and a duct 4 into a bathroom 5 and a dressing room 6. Each room is provided with a bathroom temperature detection means 7 and a changing room temperature detection means 8, and based on their output results, the set temperature set by the bathroom temperature setting section 9 and the changing room temperature setting section 10 and the temperature of each room are determined. An air conditioning control unit 13 that compares the current temperature in the bathroom temperature comparison unit 11 and the undressing room temperature comparison unit 12 and controls the air conditioning.
The control circuit 14 includes a control circuit 14 and control actuators such as a damper 15. Further, there is a changing room air conditioning state determining means 16 which changes the set value of the changing room temperature setting section 10 in response to a signal from the bathroom temperature detecting means 7, and information on the entry and exit of the user from the changing room air conditioning state determining means 16. A timer 17 is provided to measure the bathing time.

The operation of the above configuration will be explained. The bathroom 5 and the changing room 6 are maintained at a certain set temperature when no user enters the room. As shown in FIG. 2, when a user enters the bathroom 5 to take a bath and starts using hot water, the temperature of the bathroom 5 rises, and decreases when the user leaves the room. Bathroom temperature detection means 7
When the changing room air-conditioning state determining means 16 recognizes the temperature rise based on the signal from the changing room and determines whether to enter the room, the timer 17 starts measuring the bathing time. The longer the bathing time, the warmer the temperature sensation will be, so as shown in FIG. 3, the set temperature of the changing room is changed according to the bathing time and sent to the changing room temperature setting unit 10 every moment. Thereafter, when the bath is finished, the temperature in the bathroom drops, a decision is made to leave the bath, and the timer finishes measuring the bath time, maintaining the set temperature at that point.

Therefore, as shown in FIG. 4, by changing the set temperature over time, comfortable air conditioning can be achieved that corresponds to the change in temperature sensation before and after bathing.

Furthermore, if you stay in the changing room for a long time after taking a bath to dry your hair, your sense of temperature will shift to the cold side.
With the same configuration, by gradually increasing the set temperature as shown in FIG. 5, it is possible to perform health-friendly air conditioning that prevents hot water from getting cold.

Although the decision to enter the room was made based on the rate of change in the bathroom temperature, the decision may also be made based on a temperature threshold.

FIG. 6 shows another embodiment in which a humidity detection means 18 is provided in the bathroom. According to the configuration of this embodiment, since the humidity increases significantly when the user uses the bathroom, it is possible to determine whether to take a bath with high accuracy.

Furthermore, FIG. 7 shows a bathroom equipped with an infrared sensor 19 as human body detection means, and the configuration of this embodiment has the advantage that it is possible to directly determine whether a human body has entered the room.

[0017]

[Effects of the Invention] As explained above, according to the air conditioner of the present invention, the following effects can be obtained. (1) In addition to determining the use of the bathroom, the bathing time is measured, and the air conditioning status of the changing room is set and controlled based on that time, so the user's temperature sensation before and after bathing is adjusted to the bathing time. A comfortable changing room environment can be created by adapting to changes in length and shortness. (2) The method of determining bathroom use using temperature detection means is as follows:
Since it can be used in conjunction with conventionally used temperature sensors, cost increases can be suppressed. (3) The method of determining bathroom use using humidity detection means is as follows:
It has good ability to follow significant changes in bathroom humidity and allows for highly accurate control. (4) The method of providing an infrared sensor for detecting the entry of a user into the bathroom has the effect of directly determining the presence or absence of a human body.
