Air flow exchange device with indoor and outdoor temperature difference adjustment function

The invention relates to an air flow switching device with indoor and outdoor temperature difference adjusting functions, in particular to an air flow switching device capable of correspondingly adjusting the temperature of the airflow to be introduced after sensing the temperature of the outdoor space.

Referring to FIG. 1 , a conventional ventilating fan 8 is disclosed. The ventilating fan 8 can be disposed on a ceiling of an indoor space, and the ventilating fan 8 has a frame 81. The frame 81 is internally provided with a motor 82 and a heating device. 83. The motor 82 is configured to drive a blade 821 to rotate to introduce air into the room from an air outlet 84 of the frame 81, and then cooperate with the heating function of the heating device 83 to generate airflow introduced into the room. Indoor warm air function. An embodiment similar to the conventional ventilating fan 8 is disclosed in the invention patent No. I400413 of the Republic of China, "Bathroom Heating Ventilation Fan".

The above-mentioned conventional ventilating fan 8 only has a single function of providing "indoor warm air", and does not provide an outdoor venting function. Moreover, although there is another ventilating fan for connecting outdoors, there is an "outdoor row". The function of the wind; however, when the ventilating fans of the above two different functions are installed and used, the user must open different mounting holes in the indoor ceiling, and the two ventilating fans must be separately installed, so that it is easy to cause inconvenience in assembly and construction. And affecting the aesthetics of the interior decoration; in addition, due to the above two different functions of the ventilation fan can only provide indoor heating and outdoor ventilation, respectively, if the general home indoor space wants to have both "indoor heating" and " When the outdoor ventilation function is used, the user must also purchase two different functions separately. The ventilation fan is easy to increase unnecessary purchase cost and is not economical.

For this reason, please refer to FIG. 2, which discloses a conventional ventilating fan 9 having both an "indoor air intake" and an "outdoor venting" function, the ventilating fan 9 having a main casing 91, the main casing 91 An air outlet 911, an air outlet 912, an air inlet 913, and an air outlet 914 are disposed, and a first fan 92 and a second fan 93 are disposed in the main housing 91. The first fan 92 is used for The air inlet 913 is sucked into the airflow of the outdoor space, and then introduced into the indoor space through the air outlet 911.

External air exchange function.

The above-mentioned conventional ventilating fan 9 has an "indoor and outdoor airflow exchange" function; however, usually the temperature of the outdoor space is not the same as the temperature of the indoor space, and if the temperature of the outdoor space is higher than the temperature of the indoor space, the airflow of the outdoor space After being sucked into the indoor space, the temperature of the indoor space will be relatively increased. For the summer season, it is easy to cause the indoor space to be too stuffy. Also, if the temperature of the outdoor space is lower than the temperature of the indoor space, when the outdoor space is When the indoor space is inhaled, the temperature in the indoor space will be relatively lowered. If it is in the winter season, the indoor space will be too cold. In other words, since the conventional ventilating fan 9 does not have the function of adjusting the indoor and outdoor temperature difference, the conventional ventilating fan 9 is likely to cause the original temperature change of the indoor space during the process of indoor and outdoor airflow exchange, so that the indoor space is not easily maintained in a comfortable state. The temperature environment, so there is still a need to improve.
