In order to achieve the above object, the present invention provides a bathing air-conditioning system for air-conditioning the atmosphere of a bathroom and an adjacent space,
In addition to heating and drying, it has air-conditioning and dehumidifying functions, and automatically switches the operation mode according to the value of the newly set bathroom and the adjacent space and the atmosphere of the outside air, and before, during and after bathing. After that, the operation mode is switched so that optimum air conditioning according to each state can be performed.

Before taking a bath, a person is in a state of being in the washroom, which is a space adjacent to the bathroom, and then moving to the bathroom.
Here, a person undresses from a state of wearing clothes and becomes naked. In this case, the washroom is not wet even though the human body is still naked, so there is no particular discomfort even when cold air or warm air directly hits the body, so it is possible to reach the room in a short time with comfortable temperature and humidity. In winter, it is cold, so heating operation is performed. In summer, it is hot, so cooling or dehumidifying operation is performed. At this time, the bathroom is still empty, but after undressing, the room temperature and humidity are adjusted in advance so that an optimal atmosphere can be obtained when people move from the bathroom. Perform heating operation, and perform cooling or dehumidifying operation in summer.

While taking a bath, a person may be immersed in the bathtub, from when the person moves to the bathroom from the bathroom adjacent to the bathroom to when the person moves to the bathroom again.
Perform a series of bathing activities such as washing the body. In this case, the washroom is empty of people, but in order to provide an optimal atmosphere when the series of bathing activities is completed and when the user returns to the washroom again, the heating operation is continued because it is cold in the winter and the summer Because it is hot, the air-conditioning operation or dehumidifying operation is continued.
At this time, the bathroom is wet due to a series of bathing activities,
When the body directly receives wind in the washing area, it feels very cold, especially in the winter, so control the wind direction and adjust the air volume to continue heating operation in winter and cooling or dehumidifying operation in summer. To do.

After taking a bath, the person wipes his / her wet body from the time when the person moves from the bathroom, which is the adjacent space, to the bathroom to the time when the person moves from the bathroom to the outside of the bathroom. Or wear clothes. In this case, the washroom is cold in the winter, and the heating operation is performed in order to be comfortable when moving to the washroom, and the dehumidification operation is performed in the summer when the body is hot after taking a bath. At this time, the bathroom is highly humid and the walls and floors of the bathroom are wet, so if left unattended, it may cause mold, so in winter, perform ventilation operation or dry operation. In summer, dehumidifying operation or ventilation operation is performed. The optimum temperature and humidity are different before, during, and after bathing. Simply turn on the automatic operation switch to automatically create an optimal atmosphere and enjoy a comfortable bath.

As a preferred embodiment of the present invention, the bathing air-conditioning system is characterized by using a heat exchange system of a heat pump system, and has the following configuration.
The bathing air-conditioning system comprises an outdoor unit installed outdoors, a bathroom unit installed on the ceiling of the bathroom, a toilet unit installed on the wall of the bathroom adjacent to the bathroom, and a remote controller. The toilet unit is
It is composed of a circulation ventilation unit that sucks air in the washroom and ventilates the suctioned air into the washroom, and a heating unit that heats the air ventilated by the circulation ventilation unit. Further, the bathroom unit is ventilated by a circulation ventilation unit that sucks air in the bathroom and ventilates the suctioned air into the bathroom, a ventilation ventilation unit that sucks the air in the bathroom and exhausts it to the outside, and a circulation ventilation unit. The heat exchange means for air conditioning the air in the bathroom, the air passage switching means for switching the air passage of the air in the air-conditioned bathroom to the bathroom side or the toilet side, and the blowing direction of the air into the bathroom It is composed of a wind direction switching means for changing, a refrigerant expansion amount adjusting means for adjusting the expansion amount of the refrigerant during dehumidifying operation, and a control means for controlling the operation of each of the means and each of the means of the washroom unit. Further, the outdoor unit, a refrigerant compression means for compressing the refrigerant, a refrigerant flow path switching means for switching the flow path of the compressed refrigerant, a heat exchange means for exchanging heat between the refrigerant and air. A ventilation means for sucking outside air to promote heat exchange, a refrigerant expansion amount adjusting means for adjusting the expansion amount of the heat-exchanged refrigerant, and a control means for operating each of the means. Further, the remote controller includes a switching unit for operating the air conditioning system during bathing, a display unit for displaying an operating state, and a control unit for operating each unit. An air passage is connected to the bathroom unit and the washroom unit by a duct, and a refrigerant flow path is connected to the bathroom unit and the outdoor unit by a refrigerant pipe. Further, the respective control means of the bathroom unit, the outdoor unit and the remote controller perform wired or wireless communication. The air passage switching means may be provided in the toilet unit or both the bathroom unit and the toilet unit. Further, the control means may be integrated in the bathroom unit, or conversely, may be provided in each unit.

Further, the outdoor unit, the bathroom unit and the washroom unit are provided with temperature sensors for detecting the outside temperature, the atmosphere in the bathroom and the washroom,
Each operation mode is switched according to the preset temperature. Furthermore, by providing a humidity sensor in the bathroom unit and washroom unit, it is possible to control the bathroom and washroom to a comfortable humidity. The remote controller has switches before bathing, during bathing, and after bathing. Before the bathing before entering the bathroom, during the bathing while in the bathroom, and when leaving the bathroom. After a certain bath, you can change the operation mode of the bathroom and washroom respectively. Also,
Based on the preset target values of the atmosphere of the bathroom and washroom before, during, and after the bathing,
The atmosphere is controlled.

[0012] When the value detected by the temperature sensor provided in the outdoor unit is lower than the preset temperature, such as in winter, when the bathing switch is pressed, the bathroom unit and the washroom unit are heated. Get started.
At that time, it is necessary to warm the bathing space in a short time to a temperature that does not feel cold even if undressing is set in advance.Therefore, the air flow direction switching means of the bathroom unit should face the washroom side and the ventilation volume of the circulation ventilation means should be Maximum, and maximum ventilation volume of the circulation ventilation means of the washroom unit.

While the bath is warm, it feels chilly when it hits the body directly, and since there is no person in the washroom, it is not necessary to overheat it. Therefore, the bathroom and washroom are set to a preset temperature. When it reaches, or when a preset time has elapsed, or when the switch is pressed while taking a bath, the bathroom unit directs the wind direction of the wind direction switching means to the upper side of the bathtub or the washroom so that the body does not hit the wind directly. At the same time, the ventilation volume of the circulation ventilation means is weakened, and the ventilation volume of the circulation ventilation means is weakened to such an extent that the toilet unit can also maintain the temperature at that time.

After the bath, the bathroom is in a high humidity state, and if left as it is, it may cause condensation on the wall surface or the ceiling surface, which may cause mold formation. When the rear switch is pressed, the bathroom unit starts drying or ventilation operation, and the toilet unit continues heating operation. In the drying operation, the wind direction of the wind direction switching means is reciprocated within the movable range so that the entire bathroom can be dried uniformly.

Next, when the value detected by the temperature sensor provided in the outdoor unit is higher than a preset temperature, such as in summer, when the bathing switch is pressed, the bathroom unit and the washroom unit are cooled. Start dehumidification operation. At that time, if the room temperature at the start of operation is sufficiently higher than the preset temperature, perform the cooling operation,
Dehumidifying operation is performed when the temperature approaches the preset temperature.
At this time, in order to achieve comfortable temperature and humidity in a short time, the air direction switching means of the bathroom unit should face the washroom side, the ventilation volume of the circulation ventilation means should be maximum, and the ventilation volume of the circulation ventilation means of the washroom unit should be maximum. And

During the bath, it feels chilly when the cold air directly hits the body, and since there is no person in the washroom, it is not necessary to cool or dehumidify excessively. Therefore, the bathroom and washroom are set to a preset temperature and humidity. When it reaches, or when a preset time has elapsed,
Alternatively, when the switch is pressed during bathing, the bathroom unit directs the wind direction of the wind direction switching means to the upper side of the bathtub side or the washroom side, weakens the ventilation volume of the circulation ventilation means, and the washroom unit also adjusts the temperature and humidity at that time. The operation of weakening the ventilation volume of the circulation ventilation means is performed to the extent that it can be held.

After bathing, the bathroom is in a high humidity state, and if left as it is, it will cause condensation on the wall surface or ceiling surface, which may cause mold formation. When the rear switch is pressed, the bathroom unit starts dehumidification or ventilation operation, and the toilet unit continues dehumidification operation. The wind direction of the wind direction switching means is reciprocated within the movable range so that the entire bathroom can be dehumidified evenly.

A human body detection sensor is provided in each of the bathroom unit and the washroom unit, and by comparing the state before detection in the bathroom and washroom with the state after detection, a person can see from outside the bathroom and washroom. It is possible to detect movements to the washroom, from the washroom to the bathroom, from the bathroom to the washroom, and from the washroom to the outside of the washroom. Since it is possible to automatically switch the operation mode in, the remote controller need only be equipped with an automatic operation switch,
The troublesome operation of switches can be eliminated. Further, the human body detection sensor is arranged so as to detect the vicinity of the entrance / exit of the bathroom and the washroom, so that the human body can be more surely detected when entering the space. Further, by using an infrared sensor as the human body detection sensor, it can be realized at a lower cost.

Further, the bathing air-conditioning system has a communication function with the hot water supply device, so that the pre-bath operation is started at the timing when the "hot water beam" or "wakasu (additional cook)" switch of the hot water supply device is pressed. Therefore, it is not necessary to operate the remote controller of the air conditioning system when taking a bath. However, if the "hot water beam" or "wakasu (additional cooking)" switch is pressed during bathing, the pre-bathing operation is not performed and the in-bath operation is continued. Further, by providing the remote controller with a level switch capable of changing the target value of the atmosphere in each space, it becomes possible to set the temperature and humidity according to the preference of the user. Further, in the bathing air-conditioning system, when the human body detecting means does not detect the presence of a person in the automatic operation mode, the extremely cold temperature state, the extremely hot temperature state, or the extremely high temperature state of each space stored in advance is stored. By maintaining an environment that is safe and comfortable to some extent by air conditioning so that it does not become a high humidity,
The target value can be reached in a short period of time before the bath, that is, when a person enters the bathroom, and energy consumption can be suppressed as compared with the case where the target value is constantly controlled.
