Abstract

A device for preventing a spray pipe orifice of a roller washing machine from dripping water and the roller washing machine, so as to solve the technical problem of residual water in a spray pipe (3) after the washing of the roller washing machine is ended. The device comprises a faucet (5), a water inlet valve (1), the spray pipe (3), a detergent tank (6), and a spray device (4). The water inlet valve (1) is connected to the faucet (5). A solenoid valve (2) is disposed on the water inlet valve (1). A water inlet opening of the spray pipe (3) is connected to the solenoid valve (2). A water outlet opening of the spray pipe (3) is connected to the spray device (4). A passage is connected between the spray pipe (3) and the detergent tank (6). Because the detergent tank (6) is communicated with air, the spray pipe (3) is communicated with the air by means of the passage; after the spay is ended and the solenoid valve (2) is shut off, balance is achieved between the spray pipe (3) and the air by means of the passage, thereby allowing residual water in the spray pipe (3) to flow out.

本发明的最佳实施方式  BEST MODE FOR CARRYING OUT THE INVENTION
[0029] 下面结合附图对本发明的具体实施方式作进一步详细地说明。  [0029] Specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0030] 如图 2所示， 为本发明实施例提出的防止滚筒洗衣机喷淋管口滴水的装置结构 示意图， 该装置包括水龙头 5、 进水阀 1、 喷淋管 3、 洗涤剂槽 6和喷淋装置 4; 进 水阀 1上安装有电磁阀 2; 喷淋管 3的入水口与一个电磁阀连接； 喷淋管 3的出水 口连接喷淋装置 4; 喷淋管 3与洗涤剂槽 6之间连接有通路 7。  2 is a schematic structural view of a device for preventing dripping of a spray nozzle of a drum washing machine according to an embodiment of the present invention, the device comprising a faucet 5, a water inlet valve 1, a spray pipe 3, a detergent tank 6 and Sprinkler device 4; solenoid valve 2 is installed on the inlet valve 1; the water inlet of the spray pipe 3 is connected with a solenoid valve; the water outlet of the spray pipe 3 is connected to the shower device 4; the spray pipe 3 and the detergent tank There is a passage 7 between the 6 connections.
[0031] 在喷淋管 3与洗涤剂槽 6之间连接通路 7以后， 由于洗涤剂槽 6与大气相通， 使得 喷淋管 3通过该通路 7实现与大气相通， 当滚筒洗衣程序结束关闭电磁阀 2以后， 即使滚筒洗衣机内部空间封闭使得喷淋管 3内残留有剩水， 但由于喷淋管 3与大 气相通， 受大气平衡的作用， 喷淋管 3内的残留水从喷淋管 3流出落入滚筒内， 在用户下次洗衣打幵门体吋， 喷淋管 3内没有残留水， 也就不会有水滴到地板上 ， 提高了用户的使用体验.  [0031] After the passage 7 is connected between the spray pipe 3 and the detergent tank 6, since the detergent tank 6 is open to the atmosphere, the spray pipe 3 is made to communicate with the atmosphere through the passage 7, and when the drum washing process is finished, the electromagnetic is turned off. After the valve 2, even if the internal space of the drum washing machine is closed, residual water remains in the spray pipe 3, but since the spray pipe 3 is open to the atmosphere, the residual water in the spray pipe 3 is from the spray pipe 3 due to the balance of the atmosphere. The effluent falls into the drum. After the user washes the door and slams the door, there is no residual water in the spray pipe 3, so there will be no water drops on the floor, which improves the user experience.
[0032] 滚筒洗衣机洗衣结束后幵启连接在喷淋管 3上的电磁阀 2， 使得水从水龙头 5流 入喷淋管 3， 并进入喷淋装置 4， 由喷淋装置 4对滚筒内部和观察视窗实施喷淋； 在喷淋过程中， 由于喷淋管 3内进水， 通路 7内也会进水， 但只要该通路 7在设计 上相比于喷淋管 3较细或者较小， 则进水就不会很明显， 即使进水， 由于该通路 连接洗涤剂槽 7， 水也会从通路 7流入洗涤剂槽 6内， 经洗涤剂槽 6落入滚筒内。  [0032] After the washing machine of the drum washing machine is finished, the electromagnetic valve 2 connected to the spray pipe 3 is opened, so that the water flows from the faucet 5 into the spray pipe 3, and enters the spray device 4, and the inside of the drum is observed by the spray device 4 The window is sprayed; during the spraying process, water is also introduced into the passage 7 due to the water in the spray pipe 3, but as long as the passage 7 is designed to be thinner or smaller than the spray pipe 3, The water inflow is not so obvious. Even if water is introduced, since the passage connects the detergent tank 7, water flows into the detergent tank 6 from the passage 7, and falls into the drum through the detergent tank 6.
[0033] 通路 7的实现形式有很多， 本发明实施例不予限制， 只要保证喷淋管 3与洗涤剂 槽 6能实现气体上的相通即可， 由于洗涤剂槽 6与大气相通， 则喷淋管 3与洗涤剂 槽 6通过通路实现气体相通后， 也就实现了与大气的相同。  [0033] There are many implementations of the passage 7 , which are not limited in the embodiment of the present invention, as long as the spray pipe 3 and the detergent tank 6 can communicate with each other on the gas, since the detergent tank 6 is connected to the atmosphere, the spray When the shower tube 3 and the detergent tank 6 are in gas communication through the passage, the same as the atmosphere is achieved.
