Abstract

PURPOSE:To realize an air conditioned state in a declothing room in response to a variation of a temperature feeling at a human body caused by taking a bath. CONSTITUTION:A bath room temperature sensing means 7 for use in sensing a temperature in a bath room 5 is disposed in the bath room. A declothing room air conditioned controlling means is provided for performing a starting or a stopping of air conditioning operation in the declothing room, a changing of a set temperature and a changing of a set amount of air or the like in response to a result of sensing of the bath room temperature sensing means 7. When a person enters the bath room, a temperature in the bath room is changed. This variation in temperature is checked and then an air conditioning state of the declothing room is changed. That is, an environment in the declothing room is changed during taking a bath and when the person returns to the declothing room after taking a bath, the environment is changed to such a condition in which a comfortable feeling can be attained.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for a changing room located close to a bathroom.

0002

2. Description of the Related Art Conventionally, as shown in FIG. 6, an air conditioner of this type has been designed to transfer heat generated by a heat source 1 to a bathroom 5 through a pipe 4 for transporting air through a heat exchanger 2 and a blower 3. , the undressing room 6, etc., are distributed, transported, and air-conditioned. That is, the bathroom temperature comparison section 11 compares the current temperature detected by the temperature detection means 7 and 8 provided in each room with the predetermined temperatures set by the bathroom temperature setting section 9 and the changing room temperature setting section 10. The output of the actuators such as the damper 15 and the heat source 1 is controlled by the output signal of the control circuit 14 made up of the air conditioning control section 13 so that the current temperature becomes the set temperature.

[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 clothing and the accumulation of heat in the human body due to bathing. In a configuration that controls to maintain a constant temperature like this, 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. For example, in winter, when the changing room is Even if the settings were set to a comfortable condition, there was a problem of feeling too hot or too cold after taking a bath.

[0004] 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.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned objects, the present invention provides a bathroom physical quantity detection means for detecting physical quantities related to the environment of the bathroom, and an air conditioning system in a dressing room based on the detection result of the bathroom physical quantity detection means. The changing room air conditioning state control means determines the air conditioning state in which the air conditioner is turned off, the set temperature is changed, and the set air volume is changed.

[0006] Furthermore, human body detection means for detecting a person entering the bathroom is provided instead of the bathroom physical quantity detection means.

[0007]

[Operation] With the above configuration, the present invention detects changes in physical quantities related to the bathroom and environment, such as temperature and humidity in the bathroom, and based on the detection results, determines whether the user enters the bathroom and adjusts the air conditioning state of the changing room. change. That is, when the user returns to the changing room after bathing, the user changes the environmental condition of the changing room to a comfortable one while taking a bath. Furthermore, instead of detecting changes in physical quantities related to the environment, the same effect can be obtained by directly detecting the user by entering the bathroom.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In FIG. 1, heat generated by a heat source 1 passes through a heat exchanger 2 to heat or cool air. This air is then passed through a duct 4 by a blower 3 to a bathroom 5,
and a changing room 6, and each room is provided with a bathroom temperature detecting means 7 for detecting the current temperature and a changing room temperature detecting means 8, which output the detected temperature, a bathroom temperature setting section 9, and a changing room temperature. The bathroom temperature comparator 11 and the undressing room temperature comparator 12 compare the set temperature preset in the temperature setting unit 10, and the damper 15 is controlled by the output signal of the control circuit 14 comprising the air conditioning control unit 13 so that the set temperature is reached. and other actuators. Furthermore, a dressing room air conditioning state determining means 16 is provided which receives a signal from the bathroom temperature detecting means 7 and changes the set value of the dressing room temperature setting section 10.

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. When a user enters the bathroom to take a bath and starts using hot water, the temperature of the bathroom increases as shown in FIG. Based on the signal from the bathroom temperature detection means 7, the changing room air conditioning state determining means 16 recognizes the temperature rise and makes a decision to enter the room, and issues a signal to the changing room temperature setting section 10 to change the set temperature. That is, by changing the set temperature as shown in FIG. 3, air conditioning can be performed in response to changes in temperature sensation on the human body side.

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. In addition, the air conditioning state can be changed, such as the set air volume, set temperature, and direction of airflow.

FIG. 4 shows another embodiment in which a humidity detection means 17 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. 5 shows a bathroom equipped with an infrared sensor 18 as human body detection means. According to the configuration of this embodiment, it is possible to directly determine whether a human body has entered the room, so that a plurality of users can take a bath in succession. This has the effect of allowing highly accurate control even when the environment is irregularly disturbed.

[0014]

[Effects of the Invention] As explained above, according to the air conditioner of the present invention, the following effects can be obtained. (1) Since the air conditioning condition of the changing room is changed while the user is taking a bath, a comfortable changing room environment can be realized in response to changes in the temperature sensation of the human body due to bathing. (2) If the bathroom physical quantity detection means is used as a temperature detection means and this determines the air conditioning status of the changing room when the bathroom is being used, a conventionally used temperature sensor can be used in combination, which increases costs. can be suppressed. (3) When humidity sensing means is used in place of the temperature sensing means described above, it is possible to follow significant changes in humidity in the bathroom, and highly accurate control is possible. (4) When users entering the bathroom are detected by human body detection means and the air conditioning status of the changing room is determined based on this, it is possible to directly determine the presence or absence of a human body, such as when multiple users take a bath in succession. This has the effect of allowing highly accurate control even if the environment is irregularly disturbed.
