Abstract

The utility model relates to a flush closestool, in particular to a dual water-sealed and negative pressure closestool, wherein, an upper trap 3, which is positioned in a bucket body 1 and is connected with the lower port of a urinal 2, is connected with a lower trap 5 via a down drain tube 4; the lower trap 5 is connected downwards with a down drain outlet 6 via the drain tube 4; the upper trap 3 is communicated with the lower trap 5 via the down drain tube 4. The utility model is characterized in that a down water seal is added on the basis of one water seal in the siphon closestool to form dual water seal and dual siphon. The utility model has the advantages of smell isolation, water saving, splash prevention, noise prevention, simple structure, low manufacturing cost and easy popularization and application.

Description

Two water seal negative pressure water closets

Technical field

The utility model relates to a kind of water closet, especially two water seal negative pressure water closets.

Technical background

In the prior art, in the bath mode, the flushing toilet seat on the market can be divided into hydrocone type and open wide and dash two kinds of formulas (being direct-flushing) now, but at present mainly based on hydrocone type.Siphonage-toilet is washed by water on one side, Yi Bian siphonage is arranged, dirt can be drained rapidly.Widely-used water closet is one curved water seal of S, and the water in the siphon wc pan is referred to as water seal, and water seal depth is meant the degree of depth from the inner sewage draining exit of water closet upper edge to the water water surface; The degree of depth of water seal is relevant with the design of water closet internal pipeline, is just to be fixed up after water closet forms by a firing, and can not adjust in the later stage at all.The water seal area then refers to the water water surface area.How many waters seems not too big difference in the water closet, is the decisive factor whether washroom has peculiar smell actually.Water is natural barrier, can play the effect of returning on the peculiar smell that intercepts, the ability size that how much has determined to intercept peculiar smell of water.50 millimeters of the water seal depths of new standard regulation are the minimum standards that intercepts peculiar smell.But need to prove,, neither intercept peculiar smell fully, just intercept the peculiar smell of the overwhelming majority even reach this standard.Except preventing that peculiar smell is excessive, another problem relevant with water seal depth etc. is exactly the toilet problem that dabbles.Result of the test learns that it is serious to dabble when just height is greater than 200mm when falling, and falling seldom dabbles when just height is less than 140mm, and critical height is 160mm.Be that siphonage-toilet has the every effect of water seal but one water seal often loses the isolated and anti-effect of dabbling because of multiple reason though the reason of these problems occurs.

From on May 1st, 2007, unite " GB6952-2005 sanitary ceramics national standard " formal enforcement of issue by State Administration for Quality Supervision and Inspection and Quarantine and national standardization management committee.New standard has been done mandatory provisions to 6 aspects such as water seal depth, water seal superficial area, water supply volume, water seal answer, supporting requirement and the anti-siphon function of flushometer of water closet, and undesirable product will withdraw from the selling market.Expressly provide in this new standard: all must not be less than 50 millimeters with the water seal depth of whole trap sanitary ceramics; The water closet water seal superficial area that is installed in horizontal plane must not be less than 100 millimeters * 85 millimeters; Water seal is replied should be not less than 50 millimeters.The antinoise water closet complex structure of economizing on water individually in addition, the cost height, not easy care and popularization also fails to overcome the above problems at all.

Summary of the invention

Goal of the invention of the present utility model is, proposes a kind ofly can make full use of water-seal principle, realizes every flavor, water saving, anti-ly dabbles, noise water closet, promptly two water seal negative pressure water closets.

Goal of the invention of the present utility model realizes by following measure, in the staving with hold last trap that the urinal end opening links to each other and be connected trap down by comb down, following trap is arranged mouth by comb down under connecting downwards.

In the utility model, last trap is promptly set up a following water seal by trap under comb is communicated with down on the basis of a water seal of original siphon toilet, form two water seals, two siphon, realization dabbles every distinguishing the flavor of, economize on water, preventing, antinoise, and structure is simple and clear, and low cost of manufacture is easy to promote the use of.

The specific embodiment

Embodiment 1: the staving 1 interior last trap 3 continuous with holding urinal 2 end openings is by trap 5 under comb 4 is connected down, and comb was arranged mouth 6 under 4 downward connections under following trap 5 passed through.

In use, carry out the part walkthrough in advance, during defecation, under suction function, dirt enters down trap 5 by entering trap 3 in advance by following comb 4, and negative pressure disappears behind the walkthrough part dirt; Separate just finish after, bath beginning, dirt enters down trap 5 through last trap 3 by comb 4 down, and enters sewer pipe through row down mouthfuls 6, because siphonage makes the whole generation of row's process down continuous negative pressure, even up to 30mmH ₂O.Negative pressure makes flow act value in advance, and flush efficiency improves, and follow-up stability of flow, and washing water quantity is reduced to 4-6L/ time, and water saving obviously.In addition, because two water seal effect, secluding air enters drainage procedure, the block noise source.

After flushing finished, negative pressure still was present between two water seals directly of

trap

3 and 5 formation of following trap, and can be maintained until next the use; Simultaneously both blocked the destruction of inertia siphon to water seal, positive negative pressure fluctuation is to the interference of water seal when also having avoided time row.Even stop using for a long time, also because the effect of two water seals makes water seal to prolong the retention time, negative pressure keeps reaching more than the week, but following trap water seal long-term existence then.

Among the utility model embodiment, last trap 3 is by trap 5 under comb 4 is communicated with down, promptly on the basis of a water seal of original siphon toilet, set up a following water seal, form two water seals, two siphon, realization dabbles every distinguishing the flavor of, economize on water, preventing, antinoise, structure is simple and clear, and low cost of manufacture is easy to promote the use of.

Claims

1. two water seal negative pressure water closets is characterized in that, in the staving (1) with hold last trap (3) that urinal (2) end opening links to each other and be connected trap (5) down by comb (4) down, following trap (5) is by arranging mouth (6) under comb (4) connection downwards down.
