Description

Dryer

The utility model relates to a kind of dryer.

At present, as the dryer of drying clothes, adopt the oven dry problem that roasting mode solves clothing of doing mostly.These electricity consumption of equipment height, oven dry are slow, influence clothing service life.

The purpose of this utility model provides a kind of employing cycling hot air-flow clothing is dried, and drying rate is fast, and power saving does not influence the clothing dryer in service life.

The utility model is achieved in that dryer comprises drying chamber, temperature controller, timer.Drying chamber is made of shell, heat-insulation layer and door.In addition, it also has radiator, heat pump, fan, aqua storage tank and pressure-reducing chamber.Radiator is loaded in the drying baker.Be equipped with by fan driven by motor the radiator back.Electrothermal tube is housed in the heat pump, and top is expanding chamber.The heat pump expanding chamber is connected with radiator top by catheter, and the bottom is connected with the radiator bottom by liquid back pipe.There is a pressure-reducing chamber radiator top.The bottom, pressure-reducing chamber is communicated with the bottom of heat pump by heat pipe.Top, pressure-reducing chamber is communicated with by blast pipe with radiator top.The back of drying chamber is provided with cold plate.Cold plate is inboard and a dividing plate is housed above the radiator.Dividing plate and cold plate constitute air-return duct.Aqua storage tank is loaded on below the dryer.Be provided with filling opening and exhaust outlet above the pressure-reducing chamber.The inching switch of often opening is housed on the liquid back pipe.Rack is housed in the drying chamber.Temperature-sensitive head is housed on the cold plate.The overtemperature switch is housed on the catheter on radiator top.A binding post of attaching plug links to each other with a pin of motor and electrothermal tube simultaneously.Link to each other with a pin of overtemperature switch behind another binding post of attaching plug polyphone timer and the temperature controller, another pin of overtemperature switch links to each other with another pin of electrothermal tube.Another pin of motor links to each other with the common junction of temperature controller, timer.Relay indicating light is connected across between the electrothermal tube bipod.The insulation indicator lamp is connected across between the bipod of temperature controller.Temperature-sensitive head links to each other with temperature controller.

During work, the filling opening adding liquid by the pressure-reducing chamber enters in heat pump and the radiator by catheter.Air in radiator and the heat pump expanding chamber enters the pressure-reducing chamber by blast pipe, is discharged by the exhaust outlet in pressure-reducing chamber again.When liquid reaches certain position, stop liquid feeding, the clothing of needs oven dry is suspended on the rack in the drying chamber.Close the door of drying chamber, connect power supply, selected drying time and bake out temperature.At this moment, relay indicating light is bright, the fan rotation.The electrothermal tube heating, the heated liquid of expanding chamber expands, and is pressed into radiator by catheter.Under fan action, hot blast enters drying chamber, makes the clothing oven dry on the rack.The liquid that is cooled in the radiator enters heat pump by liquid back pipe and adds thermal expansion once more, and circulating successively provides heat to radiator.The humid air that has moisture content in the drying chamber becomes the globule through air-return duct and flows into tank under the cold plate effect.When the air-return duct temperature reaches the temperature of setting, pass to temperature controller by temperature-sensitive head and cut off the electricity supply.At this moment relay indicating light goes out, and the insulation indicator lamp is bright, and electrothermal tube stops heating, and expanding chamber no longer provides heat to radiator.Blower fan continues rotation makes the air-flow circulation.When the air-return duct temperature was lower than design temperature, temperature controller was connected power supply, and relay indicating light is bright, and the insulation indicator lamp goes out, the heat pipe heating, and the liquid in the expanding chamber adds thermal expansion once more, and is pressed into radiator, and hot blast is blown into drying chamber under fan action.When radiator pressure superpressure, by blast pipe gas-liquid mixture is entered the pressure-reducing chamber, subtract pipe replenishes liquid from discharge to heat pump by leading again.When blower fan occurs when unusual, radiator stops heat radiation.During the liquid back pipe overtemperature, expanding chamber liquid surpasses design temperature, the outage of overtemperature switch, and heat pipe stops heating, and relay indicating light goes out, and the insulation indicator lamp does not work, and shows fault.

Reset valve is in normally open, is used to regulate the backwater amount, to change the expansion temperature of expanding chamber.

The liquid working substance that heat conduction is used is preferably the distilled water of no any chemical hazard.

The utility model has the advantages that power saving, drying rate is fast, does not influence the service life of clothing.
