[Industrial applications]

 The present invention relates to a warm air circulation device that maintains room temperature at a constant temperature by heating and circulating indoor or outdoor air, and in particular, discharges aroma components emitted by aroma substances together with warm air and warm air. The present invention relates to a warm air circulation device characterized by preventing dew condensation on a window glass, etc., and heating and introducing outside air in conjunction with driving of an indoor ventilation device.

[0002]

[Prior art]

 In recent years, the airtightness of the room has increased throughout the entire building including offices, and unlike conventional wooden buildings, the natural ventilation function has declined significantly.

[0003] With the increasing confidentiality in the room, health problems due to the occurrence of mites and molds, gas accidents, carbon monoxide poisoning, etc. have frequently occurred. In order to deal with such a situation, a method of opening a window or operating an indoor ventilation device to ventilate the room is adopted.

However, when the windows are opened or the indoor ventilation device is operated to ventilate the room, the air that has already been heated flows out to the outside or the cool outside air outside. It will flow into the room as it is, and the room temperature will drop.

This is not preferable from the viewpoint of energy saving that efficiently heats the room, and also from the viewpoint of maintaining a comfortable indoor environment in which the room temperature is kept constant. .

Further, as the living time in a room becomes longer, it is required to create a healthy and more comfortable indoor environment. As an example, various deodorants and fragrances are placed in the room to eliminate unpleasant odors in the room and to eliminate stress, irritability, etc. by the fragrance components emitted by the fragrance. ing. However, even if only a fragrance or the like is installed, the aroma component does not spread evenly throughout the room, and the effect is not always sufficient.

In particular, in a place such as a toilet, which is not generally equipped with heating, is extremely cold in winter, and needs deodorization as appropriate, measures are required from the above viewpoint.

Further, due to the temperature difference between indoor and outdoor due to the heating in winter, the dew condensation on the window glass, the wall surface, etc. is considered as one of the causes of the occurrence of mites, molds, etc. It is a problem.

[0009]

[Problems to be solved by the device]

 The present invention has been made to solve the above problems, and its purpose is to heat and circulate air inside or outside the room while discharging various aroma components to keep the room temperature at a constant temperature. Depending on the operation of the warm air circulation device held in the room, or the warm air circulation device equipped with a warm air induction tool to prevent the formation of dew condensation on window glass, etc. It is an object of the present invention to provide a warm air circulation device capable of heating and introducing air into a room.

[0010]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention comprises a warm air circulation device as described in the scope of utility model registration.

[0011]

[Action]

 The temperature of the air in the room is detected by the room temperature detecting means, and the air is sucked in through the suction port by the air blower arranged in the housing. The air inhaled from the air inlet is blown together with the aroma component emitted by the aroma substance contained in the container, and is discharged from the air outlet together with the warm air through the heating element. The heating element is controlled by the control means so as to keep the room temperature at a preset temperature based on the detection signal of the room temperature detecting means. When unnecessary, the switching of the switching unit cuts off the power supply to the heating element, and only the fragrance component can be blown except in winter.

Further, it is possible to arrange the suction port so as to communicate with the outside air and introduce the heated outside air into the room.

Further, since the intake port is arranged so as to communicate with the outside air, and the heated outside air is introduced into the room by operating the warm air device in conjunction with the driving of the indoor ventilation device, the room temperature is increased. Ventilation of the room will be carried out while maintaining constant.

Further, a tubular warm air guide having a plurality of warm air holes is arranged at the discharge port so that the warm air blown from the warm air holes is blown toward the window glass or the wall surface. This prevents dew condensation caused by the temperature difference between the outside and the surface of the window glass.

The heat generation of the heating element 15 is controlled by the room temperature adjustment dial 69 so as to maintain a predetermined room temperature set in advance. The room temperature sensor 17 is attached to the suction portion of the suction port 3 on the back surface of the partition plate 25 by a sensor mounting bracket 71. For adjusting the indoor temperature, for example, when the indoor temperature is always set to 25 ° C, when the temperature of the inflow air at the inlet 3 reaches 26 ° C, the heating element 15 is de-energized and the inflow air becomes 24 ° C. When the heating element 15 is energized, it is controlled by the room temperature sensor 17 and the thermostat 19.
