Description
Technical field
The present invention relates to a kind of device of putting various washing agent of use in washing machine, more precisely can be along with each washing process drop into washing agent and softening agent for fibres to the inboard of sink, but also the invention of detergent supply device aspect that can drop into the washing machine of bleaching agent.
Background technology
General automatic washing machine has following structure: as the fire hose is first-class can be from the water-supply source of outside supplying washing water, the water hose that is attached on the above-mentioned water-supply source is attached on the feed-water valve of washing machine, detergent supply device is arranged on inside one side of washing machine, above-mentioned detergent supply device is accommodated required washing agent of each washing process and softening agent for fibres, and can be to the inboard supplying detergent of above-mentioned sink according to the washing process of appointment, the preparation washing can be automatically carried out in the control of the controlling organization by user operation, formal washing, in the time of a series of washing process such as rinsing washing and dehydration, various washing process is carried out in the inboard that washing agent that above-mentioned each washing process is required and softening agent for fibres are fed to above-mentioned sink.
The oblique view of the detergent supply device of Fig. 1 prior art.Structure and operation to the detergent supply device of prior art describes with reference to the accompanying drawings.
The detergent supply device of above-mentioned prior art comprises feed-water valve 10, distributor (dispenser) 30 and washing agent bucket 40 substantially.Above-mentioned feed-water valve 10 is made up of preparation washing valve 11 and formal washing valve 12; When above-mentioned distributor (dispenser) 30 is connected the preparation washing valve 11 of above-mentioned feed-water valve 10 and formal washing valve 12 by flexible pipe 21 with flexible pipe 22, is divided into the preparation washing and washs to water route 33 for water route 31, formal washing to water route 32 and rinsing; The preparation of above-mentioned washing agent bucket 40 corresponding above-mentioned distributors (dispenser) 30 is washed and is washed to water route 33 for water route 32 and rinsing to water route 31, formal washing to be divided into preparation washing washing agent injection mechanism 41, formally to wash washing agent injection mechanism 42 and rinsing washing washing agent injection mechanism 43, and is being inserted on the above-mentioned distributor 30 of can drawing.
Above-mentioned washing agent and softening agent for fibres are put into the preparation washing washing agent injection mechanism 41 that is divided on the above-mentioned washing agent bucket 40, the inboard of formal washing washing agent injection mechanism 42 and rinsing washing washing agent injection mechanism 43, start above-mentioned washing machine then, above-mentioned washing machine then can carry out each washing process by the control of above-mentioned controlling organization, again will be by washing to water route 31 with above-mentioned preparation, the washings that the above-mentioned feed-water valve 10 that formal washing washs for water route 32 and rinsing to be connected to water route 33 feeds water mix with above-mentioned washing agent or softening agent for fibres, flow into the inside of above-mentioned sink afterwards.
Said structure is further described then, in the preparation washing, earlier by above-mentioned preparation washing valve 11 supplying washing water, and then wash flexible pipe 21 by preparation the above-mentioned preparation that above-mentioned washings are fed to above-mentioned distributor (dispenser) 30 inboards is washed on the water route 31, flow into corresponding above-mentioned preparation afterwards and wash in the preparation washing washing agent injection mechanism 41 to the above-mentioned washing agent bucket 40 of water route 31 downsides, mix the inside of putting into above-mentioned sink with washing agent in being housed in preparation washing washing agent injection mechanism 41; In formal washing, washings at first according to sequencing through formal washing valve 12, formally wash flexible pipe 22 and water route 32 is given in formal washing, then with the formal washing washing agent injection mechanism 42 that is housed in above-mentioned washing agent bucket 40 inboards in washing agent mix the inside of putting into above-mentioned sink.By the decomposition of frictional force in the above-mentioned sink and washing agent, can improve scourability.
In the rinsing washing, wash valve 11 and formal valve 12 supplying washing water simultaneously of washing by open above-mentioned preparation simultaneously, and the rinsing that above-mentioned washings are fed to above-mentioned distributor (dispenser) 30 washed to water route 33 sides, then be housed in above-mentioned rinsing washing washing agent injection mechanism 43 in softening agent for fibres mix the inboard of putting into above-mentioned sink.By the effect of above-mentioned softening agent for fibres, can make washings submissiveer.
Variation and functional raising along with the washing agent that occurs in recent years, make the user in order to remove the booty on the washings or to make washings distinct more, bleaching agent need be put into the inboard of above-mentioned sink in the rinsing washing stroke stage, and the detergent supply device of aforesaid prior art can only be simple in washing stroke or rinsing stroke, drop into washing agent or softening agent for fibres washs and the rinsing function to the inboard of above-mentioned sink, the device that can supply bleaching agent but additionally is not set, therefore according to user's multiple requirement, the washing machine of above-mentioned prior art has the limitation on the function.
This shows that the structure of the placement washing agent of above-mentioned existing use in washing machine still has many defectives, and the assistant officer waits to be improved.
