The present disclosure relates to a toilet, in particular to a ceramic pressure-flushing apparatus and a flushing method thereof.
A siphon jet toilet is a toilet with further improvement on the siphon toilet. An additional jet channel is provided at the bottom of the toilet bowl facing the center of the main outlet hole. When a flush is activated, a part of water flows down from the dispensing holes arranged around the rim of the toilet seat, and a part of water is jetted out from the jet hole. Besides the siphon effect, this type of toilet allows a stronger rush of water to quickly drive the waste into trap down the drain.
Referring to Chinese patent application No. 202021791830.8 tiled “a toilet flushing nozzle with venturi effect”, the working principle of the toilet flushing nozzle in practice is as follows: when the toilet flushes, pressurized water flows in through a water inlet end cap 0, since the water inlet end cap 0 has a relatively larger diameter, a pressure loss of the pressurized water A can be reduced during water feeding, and the water flow rate will increase after passing through the booster pipe 10 having gradually changing cross section after the water flow enters. With increased water flow rate, the pressurized water A enters a separation chamber constructed by the booster pipe 10 and the spray expansion pipe 11 and forms a negative pressure suction part. The negative pressure will cause the water in the water seal recess to be sucked through a gap between the spray expansion pipe 11 and the sleeve tube 3. The sucked sealing water B passes through the separation chamber to be combined with the pressurized water A with certain kinetic energy, so as to form confluence water C that is then sprayed out from the spray expansion pipe 11, such that the ejected flushing water has greater kinetic energy. However, the inventor found that when the negative pressure suction part sucks the sealing water from the water seal recess to increase the forcefulness of the flush, the particulate matter in the waste will block the negative pressure suction part, causing insufficient usage of the sealing water by the negative pressure suction part, thereby weakening the effect of the pressure-assistant flush and making it ineffective to improve the flushing performance.
The present disclosure provides a ceramic pressure-flushing apparatus which can effectively solve the above problems.
The present disclosure is achieved by the following solutions.
A ceramic pressure-flushing apparatus, comprising:
As a further improvement, the water supplement structure is internally provided with a ventilation plane having a top opening higher than the sealing water in the water seal recess.
As a further improvement, the diameter of an outer edge of a side of the sleeve tube in an axial direction proximal to a water outlet end is larger than the diameter of the lower flushing port.
As a further improvement, a side of the sleeve tube in the axial direction proximal to a water inlet end at least partially extends out of the toilet chamber to form a protrusion, and the protrusion matches with a nut to fix the lower jet nozzle in the lower flushing port.
As a further improvement, a bottom surface of the water supplement structure is located above the sleeve tube and the water mixing area, when water is refilled into the water seal recess by the upper flushing port, the water will partly flow into the water mixing area through the negative pressure port to refill water into the water supplement structure.
As a further improvement, the water supplement structure is arranged in the interior of the toilet chamber, the water supplement structure is separated from the water seal recess by a ceramic partition, and a bottom part of the ceramic partition is biased against an outer peripheral surface of the sleeve tube.
As a further improvement, a length of the water mixing area is defined as d, a distance between the ceramic partition and an inner sidewall of the toilet chamber is defined as D, and d<D.
As a further improvement, the water supplement structure further includes a first ventilation pipeline, the water supplement structure is in an air communication with an exterior through the first ventilation pipeline, and a top opening of the first ventilation pipeline is higher than a liquid level of the sealing water after water refilling.
As a further improvement, the water supplement structure includes an external water tank arranged in an exterior of the toilet chamber, a water outlet end of the external water tank is connected to the water mixing area through a water supplement pipe, and a water inlet end of the external water tank is connected to an external water source.
As a further improvement, the water supplement structure further includes a second ventilation pipeline, the water supplement structure is in air communication with the exterior through the second ventilation pipeline, and a top opening of the second ventilation pipeline is higher than the liquid level of the sealing water after water refilling.
A ceramic pressure-flushing method, comprising the above-mentioned ceramic pressure-flushing apparatus, and specifically comprising the following steps:
The present disclosure has the following advantages.
The present disclosure provides a water supplement structure which is configured separately. When the lower flushing nozzle flushes, the water in the water supplement structure can be sucked and drawn through the negative pressure port on the venturi tube based on the principle of negative pressure, thereby increasing the amount of flushing water and improving the siphon effect. At the same time, since the water being sucked is not directly from the water seal recess, there is no need to worry about the suction channel which may be affected by the waste from the toilet bowl.

Referring to
A ceramic pressure-flushing apparatus includes a toilet chamber 1. Since the ceramic pressure-flushing apparatus is a siphon jet toilet, it has an upper flushing flow passage and a lower flushing flow passage. Correspondingly, a lower flushing port 12 and an upper flushing port 11 need to be arranged in the toilet chamber 1 for installing a lower jet nozzle 2 and an upper jet nozzle.
In view of the exterior, in order to provide pressurized water to the lower jet nozzle 2 and the upper jet nozzle, a pressurized water control valve 4 is required, wherein the pressurized water control valve 4 includes three flow passages, a first flow passage includes an input pipe 41 connected to an external pressurized water source, a second flow passage includes a first output pipe 42 connected to the upper jet nozzle to provide swirling water flow for cleaning and rinsing the toilet bowl, and a third flow passage includes a second output pipe 43 connected to the lower jet nozzle 2 to provide water flow for flushing. The opening and closing of each flow passage of the pressurized water control valve 4 can be controlled by electrical or mechanical means.
Conventionally, a spraying nozzle with a solenoid valve is often used and directly fixed in the lower flushing port 12. In the present disclosure, a spraying nozzle with a venturi tube 22 installed in the lower flushing port 12 is provided, and the water in the water seal recess 13 is sucked by negative pressure to increase the water volume. A gap formed between a sleeve tube 21 and the venturi tube 22 is a negative pressure suction part and acts as a water suction channel.
In view of the above description, the water mixing area refers to the water mixing zone between the sleeve tube 21 and the water supplement structure 3. It should be particularly emphasized that no matter whether the water supplement structure 3 is configured externally or internally, a water mixing area should always be provided.
In the present embodiment, the water supplement structure 3 is separately set on the original toilet structure during the molding stage of the toilet chamber 1. Referring to

In other embodiments, the lower jet nozzle 2 may be directly fixed in the lower flushing port 12 by means of glue injection or nesting, provided that the lower jet nozzle 2 and the lower flushing port 12 are perfectly and exactly matched.
It should be particularly emphasized that only part of the outer edge of the sleeve tube 21 that matches with the fastening nut protrudes out from the lower flushing port 12 and extends into the water seal recess 13, while most of the sleeve tube 21 is located inside the lower flushing port 12. The position where the water supplement chamber 31 corresponds to and communicates with the sleeve tube 21 is configured at the part of the sleeve tube 21 in the lower flushing port 12, wherein the position of the mixing holes 211 is also in this part. In this embodiment, four mixing holes 211 are provided, namely, there are mixing holes 211 in four orientations of the outer circumferential surface of the sleeve tube 21, which can not only ensure the water inlet area, but also provide a larger flow space for water storage.
Furthermore, the sleeve tube 21 may be formed integrally and fixed, or the sleeve tube 21 may be arranged in sections. For example, the sleeve tube 21 may be divided into front and rear halves, with the front half being inserted into the sidewall of the water seal recess, the rear half and the front half are detachable, which can facilitate assembly and disassembly of the front and rear halves of the sleeve tube 21.
In the present embodiment, a space is directly set aside during the formation of the ceramic, and the entire toilet chamber 1 is divided into two chambers by the ceramic partition 131, one chamber is the water seal recess 13, and the other chamber is the water supplement chamber 31. In order to ensure the sealing performance between the water supplement chamber 31 and the water seal recess 13, the bottom of the ceramic partition 131 is biased against the outer peripheral surface of the sleeve tube 21.
Furthermore, the ceramic partition 131 has a lower curvature at an upper half part to offer water storage space for the water supplement chamber, while the ceramic partition 131 is tilted downward with a higher slope at the lower half part to facilitate drainage of the waste and water.
From the above description, it can be inferred that the mixing holes 211 must be set between the ceramic partition 131 and the inner sidewall 132 of the toilet chamber 1, and the maximum length of the mixing holes 211 cannot exceed the distance between the ceramic partition 131 and the inner sidewall 132 of the toilet chamber 1, otherwise water will easily leak through the lower flush port to the water seal recess 13 or leak to the exterior of the toilet.
In another embodiment, a ceramic pressure-flushing method is provided which includes the above-mentioned ceramic pressure-flushing apparatus and the following specific steps:
The above flushing method can increase the water volume while improving the siphon effect, such that the toilet can be better cleaned when flushing down the waste.
The difference between this embodiment and the first embodiment is that the water supplement structure 3 is arranged in the exterior of the toilet chamber 1.
In the embodiment 1, the structure that the water supplement structure 3 is arranged in the interior of the toilet chamber 1 is specifically described, and the water refilling method of the water supplement structure 3 is that the water supplement structure 3 communicates with the water seal recess 13 and the water supplement structure 3 is refilled with water when the water seal recess 13 is refilled.
Referring to
In addition, similar to embodiment 1, in order to avoid siphoning in the water tank 321, a second ventilation pipe 3211 is provided at the top of the water tank 321, and the opening of the second ventilation pipe 3211 is higher than the top of the liquid level after the sealing water in the water seal recess 13 is refilled.
The above description only involves a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
