Description

干衣机滚筒的前支撑密封装置 Front sealing means supporting the dryer drum

技术领域 FIELD

[0001] 本发明涉及一种干衣机滚筒的支撑和密封装置,特别是干衣机滚筒的前部支撑装置及其密封装置。 [0001] The present invention relates to a device for supporting and sealing the dryer drum, especially the first supporting means and the sealing means of the drum dryer.

背景技术 Background technique

[0002] 干衣机工作时滚筒处于高载荷的运转状态,目前滚筒的支撑方式已经从单纯依靠前板摩擦片来承载过渡为采用与滚筒切合的可自由滚动的小轮实现滚筒前部的支撑,因此前支撑件的结构不仅要实现与滚筒的方便连接,还要为支撑小轮留出合适的能够与滚筒配合的位置。 [0002] The drum dryers work in a high load operation state, the present embodiment has a support drum rely solely on the friction plate to the front plate carrier transition to employ small free rolling wheel support drum to achieve meet the front portion of the drum Therefore, the structure of the front support member is connected not only to achieve convenience of the drum, but also to support a suitable leaving small wheels capable of cooperating with the drum position. 另外,由于滚筒的前支撑件要实现与滚筒和干衣机前面板的连接,所以前支撑件上还要设置干衣机的排风道、出风口及滤屑装置。 Further, since the front support drum to achieve the connection with the drum dryer and the front panel, is also set to the dryer exhaust passage on the front support member, the outlet means and filter chip. 现有技术干衣机滚筒的前支撑件如图1所示,采用钢板直接冲压的方式,在钢板上冲压出凸棱11'和内凹12'部分,内凹部分还需压制干衣机的排风道和出风口,干衣机的滚筒2'直接套于凸棱11'上。 The front support member prior art dryer drum shown in Figure 1, the direct use of steel stamping manner, punched out rib 11 'and concave 12' portion, the concave portion needs to press the steel sheet in the dryer drum exhaust passage and an air outlet, the clothes dryer 2 'directly set in the rib 11'. 由于干衣机的线屑过滤装置设于排风道内,而线屑过滤装置在安装时最好要向滚筒内倾斜一定的角度, 用于增加过滤效果和防止线屑掉入滚筒,并且倾斜角度越大效果越好;因此排风道和出风口也必须相应倾斜一定的角度以安设过滤装置。 Since the clothes dryer lint filter means disposed in the exhaust passage, and preferably would like lint filter means mounted within the drum is inclined at a predetermined angle, and for increasing the filtering effect of preventing the wire shavings do not enter the drum, and the tilt angle the greater the better the effect; thus flues and outlet must be correspondingly tilted at an angle to install filtering device. 而钢板在冲压时,过度的拉伸可能会引起钢板表面的褶皱、破损甚至拉裂,其拉伸程度有限,因此现有技术滚筒前支撑件的结构存在很大的局限性,一定程度上无法满足冲压出更大的倾斜角度的要求。 And punching the steel sheet at the time, may cause an excessive tensile steel sheet surface wrinkle, crack or even break, tensile limited extent, there is significant limitations prior art front cylinder support structure, to a certain extent can not punched out to meet the requirements greater inclination angle. 而其它材料,例如塑料件虽然具有比钢板更好的成型性,但是,由于支撑件本身所需的复杂结构,使支撑件采用工程塑料等整体成型也难以实现。 While other materials, such as plastic molded parts, although better than steel, but, due to the complexity of the required structural support member itself, the support member integrally molded of engineering plastic and the like is difficult to achieve.

[0003] 另外,如图1所示,由于滚筒套在前支撑件上后需要在滚筒2'和前支撑件Γ之间密封,现有技术是将密封条3'缠绕于滚筒内壁,使滚筒内壁与前支撑件1'接触、摩擦。 [0003] Further, as shown in FIG 2 due to the need of the drum after the drum jacket front support members 'between the sealing member and the front support Gamma], the prior art is the sealing strip 3' is wound around a drum inner wall of the drum inner wall of the front support member 1 'into contact friction. 干衣机工作时,干衣机滚筒处于高负荷旋转状态,虽然滚筒2'有支撑件上的小轮支撑,但是受力仍然不均衡,由此导致滚筒内的密封条在某些部位磨损严重,从而导致密封效果的下降。 When working dryer, drum dryers in rotation high-load state, while the roller 2 'has a small support wheel on a support member, but the force remains uneven, thereby resulting in the seal portion of the drum in some severe wear , resulting in a decline of the sealing effect.
