BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary ventilation, heating and drying system comprising a bathroom and a changing room, and a sanitary ventilation fan suitable for the system.

0002

[Prior Art] Conventionally, in a sanitary facility where a bathtub and a changing room are adjacent to each other, methods for independently achieving ventilation, heating, and drying conditions and combining these conditions have been used to comfortably and effectively utilize the bathroom and changing room. Various systems have been proposed that correspond to various conditions.

For example, Japanese Patent Application Laid-Open No. 55-146375 discloses that ducts are arranged vertically in the wall between the bathroom and the changing room, and the upper and lower parts of the duct are connected to the bathroom side air intake, which communicates with the bathroom. In addition to providing an intake port and a bathroom side discharge port, a dressing room side intake port and a dressing room side discharge port are provided at the top and bottom of the duct to communicate with the dressing room, and each intake port and each discharge port are provided with valves that can be opened and closed respectively. A clothes drying device for a bathroom is disclosed, which is installed in a duct and has a warm air fan provided in the duct, and not only dries clothes in the bathroom but also heats a changing room.

[0004] Furthermore, Japanese Patent Application Laid-open No. 61-288899 discloses a heat exchange unit in which a duct communicating with outside air is provided between a bathroom and a sub-air conditioning room (dressing room) to enable intake and exhaust, and heat is exchanged between the intake and exhaust. A bathroom drying device is disclosed in which a heater is installed to increase the drying capacity of the bathroom and to facilitate heating and ventilation between the bathroom and a sub-air conditioning room.

[0005] Japanese Patent Application Laid-open No. 62-69049 discloses a ventilation device for ventilating, drying, heating and blowing air in two rooms such as a bathroom and a washroom. A configuration is disclosed that includes a heater provided in a section and a damper that selects air blowing.

[0006]

[Problem to be Solved by the Invention] However, the above-mentioned bathroom clothes drying device requires ducts installed up and down inside the wall, which increases the cost and equipment, and also cannot be used in an existing bathroom block. It is. Moreover, the above-mentioned bathroom drying device also has the problem that the equipment is large-scale and the cost increases, and it cannot be used in an existing bathroom block.

[0007] Since the above-mentioned ventilation device is provided with two outlet ports and two intake ports, the device becomes complicated and large, and it is impossible to mount it on a partition wall.

[0008] This invention was made in order to solve the above-mentioned conventional problems, and it is possible to effectively realize ventilation, heating, and drying conditions in a sanitary room where a bathroom and a changing room are adjacent to each other by using a simple structure. The purpose of the present invention is to provide a sanitary ventilation, heating, and drying system that can be used as a sanitary ventilation, heating, and drying system, and a sanitary ventilation fan that is suitable for the system.

[0009]

[Means for Solving the Problems] Therefore, the sanitary ventilation, heating, and drying system according to the present invention provides a sanitary system consisting of a bathroom equipped with a bathtub and a changing room adjacent to the bathroom. It has an exhaust port equipped with an exhaust fan at the top, an air supply port at a relatively upper part of the wall surface of the dressing room, and a pipe penetrating into both rooms at a relatively upper part of the partition wall between the bathroom and the dressing room. A sanitary ventilation fan having a heater and a discharge port switching damper is provided in the vent, and the sanitary ventilation fan selectively switches and discharges the air in the dressing room to either the bathroom or the dressing room. The present invention aims to achieve the above object through its characteristic configuration.

[0010] Furthermore, the sanitary ventilation fan according to the present invention is a sanitary ventilation fan installed on a partition wall between a bathroom and a changing room, and has one air supply port opening to the changing room side and an air supply opening opening to the bathroom side. a first discharge port that opens to the dressing room side, a second discharge port that opens toward the dressing room side, a switching damper that switches the flow path of the discharged air so that the discharge air is discharged from either of the two discharge ports, and a heater. The purpose of the present invention is to achieve the above object by a configuration characterized by the following.

[0011]

[Function] The sanitary ventilation, heating and drying system according to the present invention having the above structure switches the air discharged from the sanitary ventilation fan provided at the vent in the partition wall between the bathroom and the changing room.
By turning on and off the heater and the exhaust fan on the bathroom wall, you can ventilate the changing room when washing and undressing, ventilate the bathroom when bathing, heat the changing room and bathroom when it is cold, and heat the changing room and bathroom after bathing. Various ventilation, heating, and drying conditions suitable for drying the body in a changing room, drying laundry hung to dry in the bathroom, etc. can be easily realized.

[0012] Furthermore, the sanitary ventilation fan according to the present invention is installed on a partition wall between a bathroom and a dressing room, and blows air from the dressing room to either the bathroom or the washroom by selecting a switching damper. Furthermore, since the heater can be turned on to heat the blown air, it can be used in the sanitary ventilation, heating and drying system to set various conditions for ventilation, heating and drying in bathrooms and changing rooms.
