Description

一种洗涤添加剂盒及洗衣机Washing additive box and washing machine 技术领域Technical field
本发明涉及洗衣机领域，特别是一种可配合洗衣机实现自动投放、多次投放的洗涤添加剂盒。The invention relates to the field of washing machines, in particular to a washing additive box which can be automatically placed and repeatedly placed in conjunction with a washing machine.
背景技术Background technique
传统的洗衣机，需要洗涤者在洗涤开始前根据经验来判断手动添加多少洗涤剂量，增加了洗涤者的工作量，还容易因为洗涤剂量的多少的控制不当造成洗不干净或浪费。于是相关技术中，就提出了洗涤剂的自动投放技术，洗涤剂分配器盒中一次倒入可供多次洗涤的洗涤添加剂盒柔顺剂，每次洗涤时根据需要自动添加。在洗涤剂分配器盒中还另有不同的洗涤添加剂盒。In the conventional washing machine, the washer is required to judge how much detergent is manually added before the start of washing, which increases the workload of the washer, and is also easy to wash or waste due to improper control of the amount of the detergent. Therefore, in the related art, an automatic dispensing technique of the detergent is proposed, and the detergent additive box softener which can be washed multiple times is once poured into the detergent dispenser box, and is automatically added as needed according to each washing. There are also different washing additive cartridges in the detergent dispenser box.
目前已有大量有关洗涤剂自动投放装置的专利申请，申请号为200610136059.9的中国专利公开了一种具有虹吸单元的洗涤剂盒的洗衣机的洗涤剂供应装置，将洗涤剂注入洗涤剂盒，在将洗涤水注入洗涤剂盒将盒内的洗涤剂稀释后从虹吸单元排入洗涤缸。该发明解决了浓洗涤剂直接进入洗涤缸所带的损伤被洗衣物的问题，但是无法实现洗涤剂的自动添加剂精确控制。There is a large number of patent applications relating to automatic detergent dispensing devices. Chinese Patent Application No. 200610136059.9 discloses a detergent supply device for a washing machine having a detergent box of a siphon unit, which injects detergent into a detergent box. The washing water is poured into the detergent box to dilute the detergent in the box and is discharged from the siphon unit into the washing tub. The invention solves the problem that the concentrated detergent directly enters the laundry to be damaged by the laundry tank, but does not achieve precise control of the automatic additive of the detergent.
申请号为201610797034.7的中国专利公开了一种用于洗衣机的洗涤剂投放装置，所述洗涤剂投放装置包括：存放腔，所述存放腔内限定有特殊洗涤剂盒安放槽，所述特殊洗涤剂盒安放槽内设有用于刺破特殊洗涤剂盒的第一顶针和第二顶针，且所述第一顶针内具有进水孔，所述第二顶针内具有出水孔，所述第一顶针和所述第二顶针均被构造成适于在端部刺入特殊洗涤剂盒后所述进水孔和所述出水孔连通所述特殊洗涤剂盒的内部空间。该发明中，通过进水孔使得进入洗涤剂盒并通过出水孔进水混合洗涤剂流出进入洗衣机内，该洗涤剂盒只能一次使用，每次洗衣均需要安装该洗涤剂盒。Chinese Patent Application No. 201610797034.7 discloses a detergent dispensing device for a washing machine, the detergent dispensing device comprising: a storage chamber defining a special detergent box seating slot in the storage chamber, the special detergent a first thimble and a second thimble for piercing a special detergent box are arranged in the box receiving slot, and the first thimble has a water inlet hole therein, and the second thimble has a water outlet hole therein, the first thimble and The second ejector pins are each configured to be adapted to communicate the internal space of the special detergent box after the end portion penetrates the special detergent box. In the invention, the water entering the detergent box and entering the detergent box through the water outlet hole and flowing into the washing machine, the detergent box can be used only once, and the detergent box needs to be installed every time.
此外，目前盛放洗涤剂和柔顺剂的洗涤添加剂盒一般为密封盒体，通过文丘里效应或负压效应或计量泵等方式将洗涤剂从盒内定量抽出。但是随着洗涤剂的抽出，密封的洗涤添加剂盒内气压越来越小，使得洗涤剂的流出越来越困难，需要一个通气结构来平衡洗涤添加剂盒内的气压，同时还要防止洗涤剂因为倾倒和振动等原因从盒内流出，并且防止外界的杂质和水分进入洗涤添加剂盒内污染洗涤剂。目前市场上的自动投放的洗涤添加剂盒一般为一次 性消费产品，即用完一盒的用量需要及时更换新的洗涤添加剂盒。这造成了资源的浪费，并且为客户匹配洗涤添加剂盒也造成了不小的困扰。In addition, the detergent additive cartridges currently containing detergents and softeners are generally sealed boxes, and the detergent is quantitatively withdrawn from the cartridge by means of a Venturi effect or a negative pressure effect or a metering pump. However, as the detergent is withdrawn, the pressure in the sealed detergent additive cartridge becomes smaller and smaller, making the outflow of the detergent more and more difficult, requiring a venting structure to balance the air pressure in the detergent additive cartridge while also preventing the detergent from being Leakage, vibration, etc. flow out of the box and prevent foreign matter and moisture from entering the detergent detergent cartridge. The automatic detergent additive boxes currently on the market are generally disposable consumer products, that is, the amount of one used cartridge needs to be replaced with a new detergent additive cartridge in time. This creates a waste of resources and creates a lot of trouble for customers to match the detergent additive cartridge.
另外，洗涤剂盒内的洗涤剂在向洗衣机内投放后，会容易留下部分液体在洗涤剂盒的底壁上，从而造成了浪费，为洗涤添加剂盒及其安装腔等的清洗也带来很大的不便。In addition, after the detergent in the detergent box is put into the washing machine, it is easy to leave part of the liquid on the bottom wall of the detergent box, thereby causing waste, and also bringing cleaning of the washing additive box and its mounting cavity. Very inconvenient.
有鉴于此特提出本发明。The present invention has been made in view of the above.
