Abstract
The invention discloses an apparatus for measuring the average drainage flow of a toilet bowl. The apparatus comprises a water tank, a draining valve, a pressure sensor, and a data processing device. The apparatus further comprises a guiding device. The water inlet of the guiding device is connected to the sewage draining exit of the toilet bowl. The water outlet of the guiding device is in a trumpet shape and is connected to the water tank. The inner side of the water outlet of the guiding device is provided with an umbrella-shaped holding base. The umbrella-shaped holding base has an interconnecting part with the tube wall of the guiding device. Water flows from the sewage draining exit of the toilet bowl into the guiding device, and flows into the water tank along a channel formed by the trumpet surface of the water outlet of the guiding device and the umbrella surface of the umbrella-shaped holding base. The invention brings forward an assessment system which can measure the flushing capability of the toilet bowl repeatedly and scientifically. With the apparatus and the method of the invention, the flushing capability of the toilet bowl can be evaluated accurately under the condition of same water consumption. Under the condition of same water consumption, the larger the average drainage flow defined by the invention is, the stronger flushing capability or washing-down capability the toilet bowl has.
Description
Technical field
The invention belongs to sanitary equipment testing evaluation technical field, average drain discharge determinator of particularly a kind of toilet seat and method.
Background technology
In the industry of toilet seat research and development and production, the mensuration that washes down the performance index of ability for toilet seat is a blank always.Though the mensuration of aquifer yield is arranged always, the ability that washes down of water consumption and toilet seat does not have inevitable relation.In one's own profession, be one for the assessment of the ability that washes down of toilet seat has major issue to be solved always.
Because the bath characteristics of toilet seat, the water yield of water outlet and current are not a steady state value, and promptly going out current is a unsteady flow or partly-filled pipe-flow.The 59th page of periodical " water supply and drainage " Vol.28 No.5 2002; Signature is " Wang Wen sea Wu Jun Qiou cloud cutting edge of a knife or a sword "; Exercise question is in the article of " measuring the cleaners and polishes discharge Curve of Sanitary Wares with the dynamic volume method ", has spoken of the method that a kind of volumetric method is measured unsteady flow.This article is also spoken of, because the influence of water level fluctuation, bigger concussion can appear in flow curve, needs software to carry out process of fitting treatment.If further reduce error, need the appropriate design cisten mechanism, effectively suppress water level fluctuation, and carry out follow-up data and handle.
Summary of the invention
The purpose of this invention is to provide average drain discharge determinator of a kind of toilet seat and method, to solve in the problem of toilet seat industry shortage for the assay method of the science of toilet seat bath ability.
Technical scheme of the present invention is; The average drain discharge determinator of a kind of toilet seat comprises water tank, draining valve, pressure transducer and data processing equipment, also comprises a guiding device; The water inlet of this guiding device connects the sewage draining exit of toilet seat; The water delivering orifice of guiding device is horn-like and inserts water tank, has a umbrella shape backing in the inboard of guiding device water delivering orifice, and the tube wall of this umbrella shape backing and guiding device has connecting portion; Current get into guiding device from the sewage draining exit of toilet seat, go into water tank along the loudspeaker face of the water delivering orifice of guiding device with the channel flow of the umbrella cover formation of umbrella shape backing.
The average drain discharge assay method of a kind of toilet seat may further comprise the steps:
In the bottom of a water tank draining valve and pressure transducer are set;
Above said water tank, place toilet seat, this toilet seat is arranged inlet water tank through a guiding device with sewage;
The water inlet of described guiding device connects the sewage draining exit of toilet seat; The water delivering orifice of guiding device is horn-like and inserts water tank; Has a umbrella shape backing in the inboard of guiding device water delivering orifice; The tube wall of this umbrella shape backing and guiding device has connecting portion, and current get into guiding device from the sewage draining exit of toilet seat, goes into water tank along the loudspeaker face of the water delivering orifice of guiding device with the channel flow of the umbrella cover formation of umbrella shape backing;
Pressure transducer is sent into the data that obtain in one data processing equipment; Through calculating the curve of water consumption and average drain discharge that obtains said toilet seat water-rinsing process; Described computation process adopts the data and curves approximating method to eliminate error; The ordinate of curve of water consumption is a flow, and horizontal ordinate is the time.
Further, behind the curve of water consumption that obtains the toilet seat water-rinsing process, this curve is carried out data fitting, and calculate the average drain discharge of this toilet seat, method is following:
The maximum displacement that makes this toilet seat is Qm, and on the ordinate of described curve of water consumption, choosing water consumption is the some A of 20%Qm and the some B that water consumption is 80%Qm, on horizontal ordinate, finds time corresponding point TA and TB respectively;
The average drain discharge of this toilet seat is Qa=60%Qm/ (TB-TA).
(TB-TA) be impulse force effective time, 60%Qm is the impulse force chresard.
Determinator of the present invention and method have proposed a kind of evaluation system that can repeatedly scientifically measure toilet seat bath ability.Use apparatus and method of the present invention can the exact evaluation toilet seat under the situation of equal water the quality of bath ability, big more with the mean displacement of the present invention's definition under the situation of same water consumption, it is strong more that toilet seat bath ability washes down ability in other words.
