Cooling and heating fan and control method thereof

Abstract

The invention relates to a cooling and heating fan and a control method thereof. The cooling and heating fan comprises a main body, an air guide assembly and a heating assembly, wherein the main bodycomprises an air outlet duct; the air guide assembly is controlled to be in an open state for enabling the air outlet duct to communicate with the external environment or a closed state for disconnecting the air outlet duct from the external environment; the heating assembly is controllably positioned at a heating position intersected with the air outlet duct or at a heating stopping position awayfrom the air outlet duct; when the cooling and heating fan is turned on, the air guide assembly is turned on; and when the cooling and heating fan is switched from the power-on state to the power-offstate, the air guide assembly is switched from the open state to the closed state according to the positions of the heating assembly. According to the cooling and heating fan, the working state of the air guide assembly can be controlled according to the positions of the heating assembly, so that the situation that a cooling and heating fan is damaged in sale and transportation due to the fact that a heating assembly does not return to the heating stopping position in time when the cooling and heating fan is switched to the power-off state and an air guide assembly is at the closed sate is prevented, and the increase of after-sales complaints and the rise of transportation cost are effectively avoided.

Description

Technical field [0001] The invention relates to the technical field of household appliances, in particular to a cooling and heating fan and a control method thereof. Background technique [0002] With the progress of society and the improvement of the level of science and technology, people's requirements for the living environment are gradually increasing, and household appliances with various functions have brought great improvements to people's living environment. As a widely used household appliance, fans can bring people cool in the hot summer. However, in the cold winter, the fan cannot be used and is in an idle state, occupying living space and bringing inconvenience to people's lives. Therefore, a cooling and heating fan that can deliver both hot air and cold air has emerged. The heating and cooling fan, also known as the convection fan, is a three-dimensional exchange system that allows indoor and outdoor air to form a three-dimensional exchange system based on the pri...

AI Technical Summary

Problems solved by technology

[0005] Based on this, it is necessary to solve the problem that the inspectors cannot accurately determine the exact position of the heating component of the cooling and heating fan during the shutdown process, and provide a cooling and heating fan and its control that can prevent the heating component from being damaged during transportation due to the failure of the heating component to return to the stop heating position method
