Cooling-heating dual-purpose tower fan

Abstract

The invention relates to the technical field of tower fans, in particular to the cooling-heating dual-purpose tower fan. The tower fan comprises a base plate and a machine body; a cold air device anda warm air device are arranged in the machine body, and the cold air device and the warm air device are arranged at intervals; the machine body comprises a base and a shell rotationally connected withthe base; the cooling-heating dual-purpose tower fan further comprises a rotating device for enabling the shell to rotate on the base; the shell is provided with a cold air inlet window, a cold air outlet window, a warm air inlet window and a warm air outlet window; and the cold air device is arranged between the cold air inlet window and the cold air outlet window, and the warm air device is arranged between the warm air inlet window and the warm air outlet window. According to the tower fan, the cold air device and the warm air device are arranged in the shell at intervals, the cold air device and the warm air device can work independently, so that cold air and/or warm air can be blown by the tower fan; and in addition, the rotating device enables the shell to rotate on the base, so that the air swinging function is realized.

Description

technical field [0001] The invention relates to the technical field of building fans, in particular to a cooling and heating building fan. Background technique [0002] The so-called "building fan" is an axial-flow electric fan. Because the overall appearance is upright like a building, it is commonly called a building fan. The upright building fan has a wide air outlet, so the area swept by the wind is relatively large. , The air flow principle of fluid physics cited by the building fan, through the rotation of the wind wheel, the wind is "thrown" from the wind wheel to form an air flow, and the air supply effect is realized. [0003] However, the existing building fans generally only have the function of cold wind or soft wind, so they can only be used in summer and autumn. As the weather gets colder, there is no fan to meet the demand for heating, or the function of cooling and heating adjustment cannot be realized, resulting in the failure of the equipment to reach the u...

Problems solved by technology

[0003] However, the existing building fans generally only have the function of cold wind or soft wind, so they can only be used in summer and autumn. As the weather gets colder, there is no fan to meet the demand for heating, or the function of cooling and heating adjustment cannot be realized, resulting in the failure of the equipment to reach the utilization rate. The maximum value, and generally the fan that realizes cooling and heating takes up a lot of space, which is quite inconvenient to use, and most building fans do not have the function of shaking the head, resulting in a fixed wind direction during use. In some larger houses, it is impossible to Achieve the effect of quickly cooling or heating the house
