Ceiling-mounted multifunctional fan comprising polluted air sterilization and purification member
InactiveCN106247443ASmooth circulation airflowEnhance cooling/heating efficiencyPump componentsDispersed particle filtrationCeiling fanComposite function
The invention relates to a ceiling-mounted multifunctional fan comprising a polluted air sterilization and purification member. The fan is simply attached to the ceiling of the interior of a building so as to generate wind and circulate indoor air, and thus the fan circulates the stagnant indoor air and makes the interior pleasant in the spring and the autumn. When the fan is used together with a cooler in the summer, the fan lowers the indoor temperature by enabling the cool air to diffuse by means of air circulation of normal rotation (blowing the wind downwards), thereby enhancing the cooling efficiency by enabling the set temperature of the cooler to be increased and excessive air conditioner operation time to be reduced. In the winter, when the fan is used together with a heater, the fan compensates for the difference between a higher indoor temperature and a lower indoor temperature by enabling the hot air at the ceiling to flow to the floor surface by means of reverse rotation (pulling the wind upwards), thereby enhancing the heating efficiency by enabling unnecessary heater operation time to be reduced. By means of one apparatus, the fan can perform multiple functions of an air circulation ceiling fan, a contaminated air sterilizing and deodorizing apparatus, a drying apparatus, an insect extermination apparatus, an anion generation apparatus, and an aesthetically excellent interior ornament.

The kiln comprises a kiln door, a kiln crown and side walls, and is characterized in that light insulation cottons are arranged on the kiln door, the kiln crown and the side walls; heavy refractory insulation plates are arranged on a fire seeing surface in the kiln; the refractory insulation plates adopt hollow structures, and are formed by splicing insulation plates; heavy refractory guide rails are arranged between upper and lower adjacent insulation plates; the insulation plates are inserted in chucks on the upper and lower sides of the refractory guide rails; and refractory fixed pieces connected with a kiln body are arranged at the middle parts of the refractory guide rails. The kiln crown, the kiln walls and the kiln door adopt all-cotton structures; the heavy refractory insulation plates are added on the internal fire seeing surface and the tabletop of a kiln car insulated by light materials at the bottom for preventing direct scouring of the wall fiber cottons by flame. Thus, even if fibers are pulverized and loosened to fall, due to stop by the refractory plates, products cannot be polluted. The kiln saves the energy, and solves the ash contamination problem.

Disclosed is an air conditioner for a vehicle, the air conditioner having an improved guide structure capable of increasing an air volume by preventing a collision between air flowing through an upper passage and air flowing through a lower passage. The air conditioner for a vehicle comprises: an air conditioning case having an air passage formed therein and an air outlet which includes a defrost vent and a face vent; and a heat exchanger for cooling and a heat exchanger for heating, which are provided in the air passage of the air conditioning case. The air conditioner for the vehicle further comprises: a temperature door arranged between the heat exchanger for cooling and the heat exchanger for heating in order to adjust the degree to which cold air, which has passed through the heat exchanger for cooling, is heated by the heat exchanger for heating; a cold air passage through which cold air that has passed through the heat exchanger for cooling bypasses the heat exchanger for heating; a warm air passage through which cold air that has passed through the heat exchanger for cooling passes through the heat exchanger for heating; a cold air guide unit for guiding the cold air downstream of the heat exchanger for cooling; and a warm air guide unit for guiding the warm air downstream of the heat exchanger for heating.
