In order to achieve the above object, the present invention relates to an apparatus main body 1 inserted into an opening 50a of a ceiling 50 such as a bathroom and the like, and air in the room such as a bathroom provided in the apparatus main body 1. Exhaust means 5 for sucking air and exhausting it outdoors
And a blower means 4 for sucking air in the room such as the bathroom and blowing the air into the room, and a heater 7 disposed in a blower passage 6 to the room, wherein the device is larger than the ceiling opening 50a. It is characterized in that the main body 1 can be installed behind the ceiling 50 from the ceiling opening 50a.

Accordingly, the decorative material provided for covering the opening from the bathroom can be made compact, and the appearance can be improved.

Further, the opening 50a of the ceiling 50 is formed to be substantially the same as or smaller than the opening of the existing ventilation fan. The installation can be performed by using the existing ventilation fan opening without providing a new ceiling opening, so that the construction can be simplified.

An exhaust air blowing means 10 which also functions as the air blowing means 4 and the exhaust means 5; an exhaust air blowing path 11 which also serves as an air blowing path to the room and an air blowing path to the outdoor;
It is characterized by comprising switching means 12 for switching the ventilation from the outside to the outside or to the inside of the room. Therefore, since the air blowing means 4 and the exhaust means 5 can be replaced by only one exhaust air blowing means and a switching means for switching the air blowing path, not only the size of the apparatus body 1 is reduced, but also the number of fans and fan motors is reduced by one. Cost can be reduced.

Further, the switching means 12 includes an opening / closing member 20 for switching the ventilation to the outside or the room, a motor 21 for moving the opening / closing member 20,
Since the opening and closing member 20 is disposed so that the rotation axis of the opening and closing member 20 is parallel to the horizontal direction, a load in the thrust direction is not applied to the motor 21. Further, the stopper and the shaft of the motor 21 can support the weight of the opening / closing member and the load of the wind pressure applied to the opening / closing member on both sides of the opening / closing member, so that the failure of the motor 21 can be reduced. And a heating / ventilating apparatus with improved characteristics can be provided.

Further, the stoppers 22a and 22b provided in the exhaust air passage 11 move when the opening / closing member 20 moves to at least one of a position for closing the exhaust port 8 for exhausting to the outside and a position for closing the outlet port 9. , The blower 1
The stoppers 22a, 22b also serve to prevent air leaking from the air blowing from
Is formed so as to overlap with a part of the opening / closing member 20. Therefore, it is possible to reliably and efficiently perform indoor heating and ventilation with a simple configuration.

As another configuration of the switching means 12, the switching means 12 comprises an opening / closing member 30 and a motor 21 for rotating the opening / closing member 30, and the rotation axis of the opening / closing member 30 is in the horizontal direction. And arranged vertically.
The opening / closing member 30 is formed in a U-shape, and an opening is formed in a side surface 32 and a lower surface 33 of the U-shape, and an opening 35b of the side surface 32 and an opening 35a of the lower surface 33 are alternately positioned. It is characterized by having an opening at the place where it does.

Thus, with a simple configuration, it is possible to reduce the number of fans and fan motors one by one.
Similarly to the above, since the load in the thrust direction of the motor 21 due to the wind pressure can be avoided, it is possible to provide a small, inexpensive, and highly reliable heating / ventilating apparatus.

If the motor 21 is constituted by a stepping motor, the opening and closing positions of the opening and closing members 10 and 30 can be finely adjusted. The opening and closing member can be appropriately moved to a position where the flow is divided, and an efficient drying operation can be performed. Further, for example, an angle detection sensor or the like necessary when a motor such as a DC motor is used becomes unnecessary, and a space for disposing the motor is not required, so that the size of the apparatus can be further reduced.

Further, if the opening / closing members 10 and 30 are made of synthetic resin or metal having excellent heat resistance, deformation of the opening / closing member due to heat from the heater 7 can be avoided, and the reliability is improved. Heating and ventilation equipment can be provided.

In order to rotate the apparatus main body 1 and insert it into the opening 50a of the ceiling, a hook 13 provided at a portion serving as a center of rotation is provided. This is characterized in that an escape portion 14 is provided to prevent the occurrence.

Therefore, at the time of construction, a part of the main unit that is larger than the ceiling opening is inserted into the back of the ceiling where the hook portion is to be scratched at the ceiling opening portion, and the device body is further centered on the scratching portion. The remaining main unit can be stored under the ceiling while rotating. Further, the opposite side of the scratching portion of the device body is provided with a relief portion for releasing contact with the ceiling opening, so that an effective space can be efficiently used while the device body fits in the ceiling opening, and Thus, a compact heating and ventilation device can be provided. In addition, since the relief portion 14 can achieve its purpose by making it R-shaped or inclined at approximately 45 degrees, the outer shell of the main body is made of a stainless steel plate or a rust-proofed iron plate, and is inexpensive such as bending and drawing. Since a simple processing method can be used, it is possible to provide an inexpensive heating / ventilation device that is compact in appearance.

Further, as another form of the heating / ventilating apparatus, a blowing means 41 provided so that a rotation axis of a fan 40a is vertical in a horizontal direction, and a rotation axis of a fan 40b is provided vertically above the blowing means 41. And a main body shell 43 surrounding the air blowing means 41 and the exhaust means 42, and the main body shell 43 is substantially the same as the opening of the existing ventilation fan. Alternatively, it is characterized in that it is formed smaller than the opening of the existing ventilation fan and has a size that fits in the ceiling opening 50a.

Therefore, while the main body of the device viewed from the bathroom side is the same as the size of the existing ventilation fan, the functional unit of the heating / ventilation device can be stored by utilizing the space in the height direction above the ceiling of the bathroom. Thus, it is possible to provide a heating / ventilating device that is compact in appearance.

Further, the exhaust means 42 is provided between the outer casing 43 of the main body and an existing functional unit such as the blower means 41.
Is provided with a ventilation path 44 for supplying the indoor air to the apparatus, so that it is not necessary to create a ventilation path using a new member, and an inexpensive heating / ventilating apparatus can be provided.

Further, the blowing means 4, the exhaust means 5,
The control box 81 includes a control unit 80 for controlling the driving of the heater 7 and the motor 21.
Is disposed around the exhaust port 8, and the exhaust port 8 is formed separately from the apparatus main body 1. The control unit 80, the blower 4, the blower 5, the heater 7, the motor 21
Are provided on the mating surfaces of the control unit 80 and the apparatus main body 1, respectively.

Accordingly, at the time of construction, together with the exhaust port 8, a control box disposed around the exhaust port 8 is installed in the ceiling opening, and then the apparatus body is mounted along the previously installed exhaust port. This has made it possible to install a heating / ventilation device larger than the ceiling opening without changing the ceiling opening. Furthermore, since the electrical contacts 90 are provided on the mating surfaces of the control unit 80 and the apparatus main body 1 respectively, the ventilation holes and the apparatus main body are automatically connected by being constructed according to the above-described procedure. And wiring and wiring behind the ceiling
It is possible to provide a heating / ventilating device with good workability by eliminating the trouble of connecting wires.

Further, a decorative member 15 is provided so as to cover the apparatus main body 1 and face the indoor side of the ceiling 50, and the decorative member 15 has a suction port 16 for sucking air in the room, An air outlet 9 for blowing out the sucked air is provided, and a filter 17 is provided between the air inlet 16 and the blowing means 4 and is detachable from the surface side of the decorative member 15. It is characterized by becoming.

Therefore, the trouble of removing the decorative member every time the filter is cleaned can be omitted, and the usability of the user is improved.

As another form of the heating / ventilating apparatus, a ventilation fan 61 for discharging the indoor air to the outside is provided.
And a ventilation fan motor 6 for driving the ventilation fan 61
2 and a main body outer shell 64 that covers the ventilation fan 61 and shapes a ventilation passage 63 for discharging air from the room to the outside. The heater 7 and the room Air blowing means 65 for sucking air and blowing out the air heated by the heater 7 into the room, and the main body shell 64 is substantially the same as the opening of the ventilation fan or is located at a position higher than the opening of the existing ventilation fan. It is characterized by being made smaller.

Therefore, since the heater 7 and the blowing means 65 are built in the interior of the decorative member 15, there is no new member to be installed behind the ceiling, and the same ventilation function as the existing ventilation fan is provided in the ceiling opening of the existing ventilation fan. Since it is stored, it is possible to provide a heating / ventilating apparatus that can be attached using an existing ceiling opening.

As a heater, for example, there is a sheathed heater. If this heating / ventilating device is to be realized by using this sheathed heater, the heat generation of the sheathed heater is stopped after reaching a certain temperature due to the characteristics of the sheathed heater. Therefore, a sensor or the like for sensing the temperature is required, and the space around the heater including the heater is increased. Therefore, in the present invention,
As the heater 7, a PTC ceramic heater was used.
The resistance of the PTC heater rapidly increases when the temperature of the ceramic portion, which is the heating element, reaches a certain temperature. As a result, the current flowing into the heating portion automatically decreases, and heat generation is suppressed. The temperature sensing sensor used can be dispensed with, and the space distance with other members can be reduced, so that the main body and the decorative member can be prevented from going forward on the bathroom side to reduce the size. Can be planned.
