The invention relates to a cooling and heating fan. The cooling and heating fan comprises a main shell, an air wheel, a heating unit and a cooling and heating switching piece; the main shell comprisesa first air outlet area and a second air outlet area which are adjacently arranged in a first direction, and the air wheel is constructed to be capable of rotating around the first direction so as togenerate airflow flowing out of the first air outlet area and the second air outlet area; the heating unit is located on the path where the airflow flowing out of the second air outlet area, the cooling and heating switching piece is located in the first air outlet area, and the cooling and heating switching piece is constructed to be capable of moving relative to the main shell so as to be capable of switching between a first position and a second position in different modes; in a cool air mode, the cooling and heating switching piece is located at the first position, and the airflow can flow out of the first air outlet area and the second air outlet area; and in a warm air mode, the cooling and heating switching piece is located at the second position, and the airflow can flow out of the second air outlet area. According to the cooling and heating fan, the cool air mode and the warm air mode are switched through the arrangement of the cooling and heating switching piece, and due tothe fact that only one air wheel is arranged, the production cost is low, and the overall weight is low.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a cooling and heating fan. Background technique [0002] With the progress of society and the improvement of science and technology, people's requirements for the living environment are gradually increasing. In order to maintain a suitable indoor temperature in hot summer and cold winter, people often buy two products: fans and electric heaters. It is used separately in summer and winter, thereby increasing consumption expenditure, taking up living space, and bringing inconvenience to people's lives. Based on this, a cooling and heating fan that can take into account both the functions of conveying hot air and conveying cold air came into being. [0003] In order to realize the function of outputting hot air and outputting cold air, the existing cooling and heating fans have relatively large volume and weight, and have relatively high manufacturing costs, which rest...
