A turntable used in a dual-purpose ceiling fan for heating and cooling

Abstract

The invention discloses a rotary table used in a cooling and heating dual-purpose type ceiling fan. The rotary table comprises an upper disc body and a lower disc body, wherein the upper disc body andthe lower disc body are combined into a whole in the up-and-down direction. Dovetail grooves which are used for being capable of achieving assembly and disassembly of fan blades are formed in the periphery of the upper disc body in an array mode, and the lower sides of the dovetail grooves extend to the lower end face of the upper disc body. An annular groove which is connected with the upper sides of the dovetail grooves is formed in the upper disc body in the annular direction. A plurality of longitudinal through holes which are used for allowing studs to pass through are formed in the upper disc body and the lower disc body in the longitudinal direction, and the two ends, passing out of the corresponding longitudinal through hole, of each stud are connected with manual screwing nuts ina rotating mode correspondingly. The portion, stretching out of the upper end face of the upper disc body, of each stud is connected with a hexagon nut and the corresponding manual screwing nut in arotating mode, and the hexagon nuts and the manual screwing nuts are used for achieving installation of blades and locking of the upper disc body and the lower disc body. A hexagonal hole groove is formed in one end of each blade in the longitudinal direction. By the adoption of the technical scheme, the fan blades and the blades can be conveniently, reliably and detachably connected, and therefore the requirement for heating or cold air supplying can be met, the effect of the indoor ceiling fan can be made full use of, and the purpose that the dual functions of supplying cold air and supplying hot air are fulfilled by the ceiling fan is achieved through a detachable structure.

Description

Technical field [0001] The invention relates to the technical field of household type ceiling fans, in particular to a turntable used in a cooling and heating dual-purpose ceiling fan. Background technique [0002] Ceiling fans are generally used for cooling and reducing heat in summer. In winter, they are basically idle. In winter, in many areas that need heating, people need additional heating equipment, especially in the bungalows in the rural-urban junction and the vast rural areas. The use of charcoal-roasting and other methods to achieve heating, especially when the charcoal-roasting fire is used for heating, the doors and windows are closed tightly, so that the indoor air is not circulated, and the insufficient combustion of charcoal is likely to produce carbon monoxide gas, which is easy to cause dizziness after people inhale too much. Poisoning has a greater impact on the body. In addition, in the above-mentioned places, ceiling fans are generally installed on the ceili...

AI Technical Summary

Problems solved by technology

[0002] Ceiling fans are generally used for cooling and cooling in summer, and are basically idle in winter. In winter, in many areas that need heating, people need to add additional heating equipment, especially in urban-rural fringe areas and rural bungalows. Heating is realized by means of burning charcoal and grilling fire, especially when heating by burning charcoal and grilling fire, the doors and windows are also closed tightly, so that the indoor air is not circulated, and the insufficient combustion of charcoal is easy to produce carbon monoxide gas, which is easy to cause dizziness after people inhale too much carbon monoxide. Poisoning, which has a greater impact on the body

In addition, in the places mentioned above, ceiling fans are generally installed on the ceiling, but in winter, the ceiling fans are always idle, which wastes resources and space. Heating needs of regions and people in winter
