Abstract
The utility model relates to a rotary-drum laundry drier which overcomes the defects that the surface of the resistance wire or the far-infrared electrothermal tube has electricity and the resistance wire or the far-infrared electrothermal tube is not safe to used or has large power consumption when the resistance wire or the far-infrared electrothermal tube is used as the heat source by using a semiconductor electric heating element P T C as the major part of the electrothermal element. The utility model has self-limited temperature and does not have the flame and has high safety, high efficiency, power saving and time saving.
Description
The utility model relates to a kind of device that is used to make cloth drying, mainly is made up of motor, blower fan, electrothermal piece, drum etc.
The drum-type dryer mainly is to utilize motor drives drum and blower fan to rotate, and blower fan sucks air and by the electrothermal piece heating, the drum of rotation makes clothing fully contact with hot-air, and the water evaporates on the clothing becomes humid air to discharge, and finally reaches the drying purpose.The electrothermal piece of existing drum-type dryer is mainly resistance wire, surface charging, and security performance is relatively poor, particularly in a humid environment, easier the user is constituted a threat to; Other has a kind of electrothermal piece of drum-type dryer to adopt far infrared electro-thermal tube, the surface is not charged, security performance is secure, but because power demand is big, power consumption is also bigger, be difficult for being accepted, and the far infrared electro-thermal tube of elongated tubular product such increased the complexity of organism internal structure, body volume is increased by the consumer.
The purpose of this utility model is to overcome the deficiencies in the prior art part, and the drum-type dryer of a kind of safety, power saving is provided.
The purpose of this utility model mainly is by adopting semi-conductor electricity thermal element PTC to reach as the major part of electrothermal piece.
Fig. 1 is primary structure figure of the present utility model, and as Figure of abstract.
Fig. 2 is the primary structure figure of the utility model electrothermal piece.
The utility model is described in further detail below in conjunction with drawings and Examples.
Motor (1) is fixed on the housing (2), drives blower fan (3) and drum (4) and rotates, and blower fan, drum are fixed by bearing (5) supporting.Electrothermal piece (6) is fixed on the preceding bottom of housing, in it mainly by semi-conductor electricity thermal element PTC(7) form, installing fin (8) in the both sides of element both can increase area of dissipation, can play fixedly PTC element again.The PTC curie point is 230 ℃, and resistance value is one kilo-ohm in the time of 25 ℃.PTC can be one, also can the polylith parallel connection.Connect power supply to PTC, can obtain to regulate automatically, have temperature from the specified heating power of limitting ability.
Open Qianmen (9) during use, clothing to be done is put into drum, close the door and starting switch makes motor work, blower fan rotates, and air enters drum from inlet (10), and is heated to 70～80 ℃ by electrothermal piece rapidly.The rotation that drum does not stop makes clothing fully contact with hot-air, the moisture on the clothing thereby be evaporated.The air that humidity is bigger is constantly discharged from outlet (11), finally reaches the purpose of drying.
The utility model adopts the major part of PTC heating as electrothermal piece, and temperature can be from limit, and the flames of anger is safe and reliable, the efficient height, economizes on electricity, saves time.Be applicable to family.
Claims (2)
1, a kind of drum-type dryer is made up of motor, blower fan, electrothermal piece, drum etc., it is characterized in that electrothermal piece mainly is made up of semi-conductor electricity thermal element PTC.
2, according to the described drum-type dryer of claim 1, it is characterized in that the semi-conductor electricity thermal element PTC of electrothermal piece can be one, also can the polylith parallel connection, elements on either side installing fin.
