Description
本发明涉及洗衣设备技术领域,具体地,涉及一种滚筒洗衣机及其控制方法。The invention relates to the technical field of laundry equipment, in particular to a drum washing machine and a control method thereof.
洗衣机作为人们日常生活中使用最为广泛的一种家用电器,帮助人们摆脱了洗衣的烦恼,给人们带来了极大的便利。但是洗衣机也具有一定的缺点,比如说耗时较长、耗水量较大等,随着社会的发展,水资源作为一种重要的自然资源变得越来越重要,人们的节水意识也随之提高,而如何实现洗衣机的节水功能便显得尤为重要。As the most widely used household appliance in people's daily life, washing machine helps people get rid of the trouble of laundry and brings great convenience to people. However, washing machines also have certain shortcomings, such as longer time-consuming and larger water consumption. With the development of society, water resources are becoming more and more important as an important natural resource, and people’s awareness of water saving also changes. Therefore, how to realize the water-saving function of the washing machine becomes particularly important.
为了解决洗衣机的节水问题,现在也提出了一些专利,比如专利号为201410215346.3,名称为一种滚筒洗衣机的中国发明专利,该发明涉及一种滚筒洗衣机,包括箱体,箱体内设有内筒和外筒,外筒与箱体之间设有门封,内筒与驱动装置相连,所述的内筒为无孔内筒,且所述的内筒为筒底处直径小、筒口处直径大的锥形筒,内筒的筒口处向内呈弧形收拢,所述的门封上设有进水导管,进水导管的一端与洗涤水快速加热装置相连,进水导管的另一端穿过门封伸入内筒内,所述的外筒上设有排水口及水压检测装置。由上述技术方案可知,该发明的内筒为无孔内筒,通过设置在门封上的进水导管实现内筒进水,并通过内筒自身的形状在脱水过程中实现排水,这样可以避免在内、外筒之间存水,大幅节约了洗涤用水量。In order to solve the water-saving problem of washing machines, some patents have also been proposed. For example, the patent number is 201410215346.3, which is a Chinese invention patent of a drum washing machine. The invention relates to a drum washing machine, including a cabinet with an inner The cylinder and the outer cylinder, a door seal is provided between the outer cylinder and the box body, the inner cylinder is connected with the drive device, the inner cylinder is a non-porous inner cylinder, and the inner cylinder has a small diameter at the bottom of the cylinder and the mouth of the cylinder. A cone with a large diameter. The mouth of the inner cylinder is curved inward. The door seal is provided with a water inlet pipe. One end of the water inlet pipe is connected with the washing water rapid heating device, and the other end of the water inlet pipe It passes through the door seal and extends into the inner cylinder, and the outer cylinder is provided with a drainage port and a water pressure detection device. It can be seen from the above technical solution that the inner cylinder of the present invention is a non-porous inner cylinder. Water can be fed into the inner cylinder through the water inlet pipe provided on the door seal, and water can be discharged during the dehydration process through the shape of the inner cylinder, which can avoid Water is stored between the inner and outer cylinders, which greatly saves washing water consumption.
上述发明提供了一种具有无孔内筒的滚筒洗衣机,但仅仅是将现有滚筒洗衣机的内筒设计为无孔结构,现实意义很小。因为衣物洗涤须有一定的洗涤水浸泡,如果要实现浸泡的效果,无孔内筒中的需要存有一定的水量,这样会增大电机的负担,耗电等问题也随之而来。另外,该专利公开的滚筒洗衣机进水的方式是通过门封,由于门封主要的作用是实现洗衣机外筒的筒口的密封,在门封上设置进水导管容易影响门封的密封效果,不易实现。The above-mentioned invention provides a drum washing machine with a non-porous inner tub, but only the inner drum of the existing drum washing machine is designed as a non-porous structure, which has little practical significance. Because laundry must be soaked in a certain amount of washing water, if the soaking effect is to be achieved, a certain amount of water needs to be stored in the non-porous inner cylinder, which will increase the burden on the motor and cause problems such as power consumption. In addition, the drum washing machine disclosed in the patent uses a door seal. Since the main function of the door seal is to seal the opening of the outer drum of the washing machine, setting a water inlet duct on the door seal easily affects the sealing effect of the door seal. achieve.

本实施例所述的增压机构包括增压孔道28和负压安全阀29,所述的负压安全阀29设置在增压孔道28上,用于内筒17内部压力小于外界环境大气压时单向导通增压孔道28,外界环境气体由增压孔道28进入内筒17内部进行增压,直至内筒17内部气压与外界环境气压平衡,负压安全阀29关闭。The pressurizing mechanism described in this embodiment includes a pressurizing port 28 and a negative pressure safety valve 29. The negative pressure safety valve 29 is provided on the pressurizing port 28 and is used when the internal pressure of the inner cylinder 17 is lower than the atmospheric pressure of the external environment. Guided through the pressurizing channel 28, the ambient air enters the inner cylinder 17 through the pressurizing channel 28 to be pressurized until the internal air pressure of the inner cylinder 17 is balanced with the ambient air pressure, and the negative pressure safety valve 29 is closed.
本实施例所述的泄压机构包括泄压孔道30和正压安全阀31,所述的泄压孔道30设置在内筒17上靠近旋转中心轴位置处且始终高于内筒17内的最高水位位置,所述的正压安全阀31设置在泄压孔道30上,用于内筒17内部压力大于外界环境大气压时单向导通泄压孔道30进行泄压,直至内筒17内部气压与外界环境气压平衡,正压安全阀31关闭。The pressure relief mechanism described in this embodiment includes a pressure relief port 30 and a positive pressure safety valve 31. The pressure relief port 30 is arranged on the inner cylinder 17 at a position close to the central axis of rotation and is always higher than the highest in the inner cylinder 17.

如图28所示意,进水时,内筒17的密封舱内的气体受压,一旦大于正压安全阀的设定值,正压安全阀打开,可以通过该泄压孔道溢出,保证气压平衡。As shown in Figure 28, when water enters, the gas in the sealed compartment of the inner cylinder 17 is pressurized. Once it is greater than the set value of the positive pressure safety valve, the positive pressure safety valve opens, which can overflow through the pressure relief port to ensure air pressure balance .
如图28所示意,突然断水时,内筒17的密封舱内的气体受压,一旦小于正压安全阀的设定值,外部大气可以迅速进入密封舱,并破坏倒吸,保证气压平衡,避免洗涤水 被吸入自来水管网。As shown in Figure 28, when the water is suddenly cut off, the gas in the sealed compartment of the inner cylinder 17 is pressurized. Once it is less than the setting value of the positive pressure safety valve, the external atmosphere can quickly enter the sealed compartment and destroy the back suction to ensure air pressure balance. Avoid washing water being sucked into the tap water pipe network.
