下面参考附图来详细描述根据本发明实施例的干衣机， 在一实施例中， 较佳为直排干 衣机。  DETAILED DESCRIPTION OF THE INVENTION A dryer according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. In one embodiment, a direct-drying dryer is preferred.
如图 3至图 6所示， 根据本发明实施例的干衣机， 包括： 桶体 10、位于桶体 10外的排 气端 101、 设在排气端 101附近的换热管道 40、 加热器 30和风扇 50。  As shown in FIG. 3 to FIG. 6, a clothes dryer according to an embodiment of the present invention includes: a tub body 10, an exhaust end 101 located outside the tub body 10, a heat exchange duct 40 disposed near the exhaust end 101, and heating. The device 30 and the fan 50.
具体而言， 桶体 10内形成有用于容纳衣物 60的容纳空间 200， 所述桶体 10上具有连 通容纳空间 200的热风进口 201和热风出口 202。  Specifically, an accommodating space 200 for accommodating the laundry 60 is formed in the tub body 10, and the tub body 10 has a hot air inlet 201 and a hot air outlet 202 that communicate with the accommodating space 200.
加热器 30设在桶体 10内且邻近热风进口 201。  The heater 30 is disposed in the tub 10 and adjacent to the hot air inlet 201.
换热管道 40包括用于将桶体 10内的湿热空气排出的第一排风管道 401，以及用于将外 部冷风补充到桶体 10内的第二进风管道 402，其中，第一排风管道 401与第二进风管道 402 通过其间的管道壁进行换热。 在本发明之较佳实施例中， 第一排风管道 401与第二进风管 道 402通过共同的中间管道壁 4011进行换热。  The heat exchange duct 40 includes a first exhaust duct 401 for discharging humid hot air in the tub 10, and a second intake duct 402 for replenishing external cold air into the tub 10, wherein the first exhaust duct The duct 401 and the second air inlet duct 402 exchange heat through the duct wall therebetween. In a preferred embodiment of the invention, the first exhaust duct 401 and the second intake duct 402 exchange heat through a common intermediate duct wall 4011.
在本发明之一较佳实施例中，第二进风管道 402套接在所述第一排风管道 401的外面。 其中， 第一排风管道 401的第一端 （即如图 3中所示的第一排风管道 401的右端） 与热风 出口 202相连且第一排风管道 401的第二端 （即如图 3中所示的第一排风管 401的左端） 与外界连通，用于将高温高湿气体从容纳空间排放到外界。第二进风管道 402的第一端（即 如图 3中所示的第二进风管道 402的右端)设在桶体 10内且第二进风管道 402的第二端（即 如图 3中所示的第二进风管道 402的左端） 与外接连通， 用于向桶体 10内补充冷风。  In a preferred embodiment of the invention, the second air inlet duct 402 is sleeved outside the first exhaust duct 401. The first end of the first exhaust duct 401 (ie, the right end of the first exhaust duct 401 as shown in FIG. 3) is connected to the hot air outlet 202 and the second end of the first exhaust duct 401 (ie, as shown in the figure) The left end of the first exhaust duct 401 shown in Fig. 3 is in communication with the outside for discharging high-temperature and high-humidity gas from the accommodating space to the outside. The first end of the second air inlet duct 402 (ie, the right end of the second air inlet duct 402 as shown in FIG. 3) is disposed in the barrel 10 and the second end of the second air inlet duct 402 (ie, FIG. 3 The left end of the second air inlet duct 402 shown therein is in communication with the outside for supplementing the cold air into the tub 10.
风扇 50设置在所述第一排风管道 401上并远离所述排气端， 用于形成风路循环。 也就是说， 当根据本发明实施例的干衣机或直排干衣机处于干衣工作状态时， 风扇 50 用于形成风路循环。 即， 冷风由换热器 40的第二进风管道 402输送入桶体 10内， 被诸如 电热丝加热器等的加热器 30加热后变成热风， 从热风进口 201进入容纳空间 200， 热风带 走洗涤完的湿衣物 60上的水分， 由热风出口 202经由第一排风管道 401排出外界。此时的 热风为高温高湿气体， 其带有大量的余热。 该高温高湿气体流经换热管道 40时， 可以对进 入桶体 10内的冷风进行预热。 根据本发明实施例的干衣机或直排干衣机， 设有换热管道 40， 当进行干衣操作时， 可 以用排出的热风的热量对进入桶体 10内的冷风进行预热， 充分利用了热量， 从而达到了节 能的目的。 A fan 50 is disposed on the first exhaust duct 401 and away from the exhaust end for forming a circulation of the air passage. That is, when the dryer or the in-line dryer according to the embodiment of the present invention is in the dry working state, the fan 50 is used to form a wind path circulation. That is, the cold air is sent into the tub 10 from the second air inlet duct 402 of the heat exchanger 40, heated by the heater 30 such as a heating wire heater, and becomes hot air, and enters the accommodating space 200 from the hot air inlet 201, and the hot air belt The moisture on the washed wet laundry 60 is discharged from the hot air outlet 202 to the outside via the first exhaust duct 401. The hot air at this time is a high temperature and high humidity gas with a large amount of residual heat. When the high-temperature and high-humidity gas flows through the heat exchange conduit 40, the cold air entering the barrel 10 can be preheated. A clothes dryer or a straight-line dryer according to an embodiment of the present invention is provided with a heat exchange duct 40. When performing a dry-coating operation, the cold air entering the barrel 10 can be preheated by the heat of the discharged hot air. The use of heat has achieved the goal of energy saving.
如图 6所示， 为增大换热管道 40的换热面积， 所述第一排风管道与第二进风管道的共 同中间管道壁 4011设计成呈锯齿状的圆周壁面。  As shown in Fig. 6, in order to increase the heat exchange area of the heat exchange duct 40, the common intermediate duct wall 4011 of the first exhaust duct and the second intake duct is designed to have a serrated circumferential wall surface.
根据本发明的一个示例，还包括过滤器 70。过滤器 70设在热风出口 202与第一排风管 道 401 的第一端之间。 由此， 可以避免衣服纤维等杂物进入换热器 40， 提高了换热器 40 的使用寿命。  According to an example of the present invention, a filter 70 is further included. A filter 70 is disposed between the hot air outlet 202 and the first end of the first exhaust duct 401. Thereby, impurities such as clothes fibers can be prevented from entering the heat exchanger 40, and the service life of the heat exchanger 40 is improved.
根据本发明实施例的干衣机或直排干衣机， 设有换热管道 40， 当进行干衣操作时， 可 以用排出的热风的热量对进入桶体内的冷风进行预热， 充分利用了热量， 从而达到了节能 的目的。 通过换热器， 回收了原本会被浪费的热量， 使热量被回收继续对衣物进行烘干， 降低了热量的浪费， 提高了干衣机或直排式干衣机的能效。  The clothes dryer or the in-line clothes dryer according to the embodiment of the present invention is provided with a heat exchange duct 40. When the dry clothes operation is performed, the cold air entering the barrel body can be preheated by the heat of the discharged hot air, and the heat is fully utilized. The heat thus achieves the purpose of energy saving. Through the heat exchanger, the heat that would otherwise be wasted is recovered, so that the heat is recycled and the clothes are dried, the waste of heat is reduced, and the energy efficiency of the dryer or the in-line dryer is improved.
