Description

Train toilet with low noise and low energy consumption

Technical Field

The invention relates to the technical field of toilets, in particular to a toilet structure with a middle transition box, which is applied to a train.

Background

Along with the rapid development of railways and high-quality and rapid service, people go out more and more conveniently. The train can be deeply driven into streets and alleys to feel unique folk-custom folk wind after the train leans to the station.

At present, in the train private room, generally all there is vacuum collection just bathroom, considers that the actual spatial layout on the train is compacter, for improving the comfortable experience of passenger's trip, the space of going to bed in the train private room can suitable increase, this space size that will corresponding crowded occupation bathroom.

The existing toilet bowl has the disadvantages that the existing toilet bowl is large in size, functional components are distributed dispersedly, the toilet bowl has large noise during pollution discharge action, and meanwhile, the system needs to be re-vacuumized every time the toilet bowl is emptied, so that the compressed air consumption of a train is high.

In addition, in the existing vacuum excrement collecting system, when a sewage inlet of a toilet is opened in the sewage discharge process of the toilet, the noise is high due to the pressure difference, and a system vacuum generator can vacuumize once every time the toilet is used. This has just caused this type of squatting pan system noise higher, and system vacuum generator frequency of operation is higher, leads to the compressed air consumption on the train great.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1 to 5, the train toilet with low noise and low energy consumption of the embodiment includes a toilet cover 2 and a toilet cover 1, wherein the top surface of the toilet cover 2 is connected with the toilet cover 1 through a hinge mechanism 13, a middle transition box 4 is fixed at the bottom position in the toilet cover 2 through a spacing support frame 14, the section of the middle transition box 4 is of a right-angle structure, a toilet bowl 3 is installed on the upper surface of the middle transition box 4 through a support member, the bottom of the toilet bowl 3 is connected with the middle transition box 4 through an inlet pipe, an inlet valve 5 is installed on the inlet pipe, an output pipe 601 is installed on the middle transition box 4, dirt is discharged through the output pipe 601, an outlet valve 6 is installed on the output pipe 601, a vacuum pipe 701 is also installed on the top surface of the middle transition box 4, and a vacuum valve 7 and a vacuum switch 9 are installed on the vacuum pipe 701; an exhaust pipe 801 is further installed on the top surface of the intermediate transition box 4, and an exhaust valve 8 is installed on the exhaust pipe 801.

A door-shaped frame 16 is fixed on the middle transition box 4, the electromagnetic valve assembly 10 is installed below the door-shaped frame 16, and the bedpan 3 is installed on the top surface of the door-shaped frame 16 through a connecting plate 15.

The intermediate transition box 4 is provided with a liquid level meter 12.

The output pipe 601 is connected to a waste tank.

A plurality of nozzles 11 are attached to the inner wall surface of the toilet bowl 3.

The cross section of the supporting frame 14 is in a Z-shaped structure.

In the actual use process:

in a standby state: in the initial state, the vacuum valve 7 is activated and opened, and the vacuum in the sewage box connected with the toilet is drained to the interior of the intermediate transition box 4 until the vacuum switch 9 is activated and the vacuum valve 7 is closed.

(II) toilet bowl activation action: the pressurized water flushes the inner surface of the bowl 3 through the nozzle 11 while the bowl inlet valve 5 opens and the waste and water in the bowl 3 is forced into the intermediate transition box 4 by the outside atmospheric pressure.

The middle transition box 4 performs pollution discharge action: after the toilet bowl is flushed for a certain number of times or the liquid level meter 12 on the intermediate transition box 4 is activated, the outlet valve 6 and the exhaust valve 8 of the toilet bowl are opened, and the dirt in the intermediate transition box 4 enters the dirt box under the pushing of the external atmospheric pressure. And then the outlet valve 6 and the exhaust valve 8 of the toilet are closed, if the vacuum switch 9 detects that the vacuum degree in the intermediate transition box 4 is reduced, the vacuum valve 7 is opened, the vacuum in the sewage box is drained to the inside of the intermediate transition box 4 again until the vacuum switch 9 is activated, and the vacuum valve 7 is closed.

The noise that the squatting pan produced when blowdown is opened by the squatting pan blowoff valve on the one hand outside atmospheric pressure promotes the filth and produces at bedpan 3 when the filth case conveys when blowdown, and the compressed air pressure release production when switching on is switched on to the function valve on the other hand.

The filth in the squatting pan finally gets into in the filth case through twice transmission, because bedpan 3 and middle transition case 4 are very close, middle transition case 4 utilizes lower vacuum alright inhale the filth in the bedpan 3 in the middle transition case 4 rapidly, because the noise that the pressure differential is less consequently produces in bedpan 3 dirt inlet department is relatively less.

The pressure relief ports on the solenoid valve assembly 10 for controlling the inlet valve 5, the outlet valve 6, the vacuum valve 7 and the exhaust valve 8 of the toilet are drained to the exhaust pipe 801 of the toilet by using hoses, and the noise generated by the exhaust pipe is drained to the lower part of the vehicle.

Because the toilet only needs to consume less vacuum degree in each flushing process, the pneumatic frequency of the vacuum generator of the excrement collecting system is reduced, the consumption of compressed air can be reduced, and the power consumption of a train is reduced.

The above description is intended to be illustrative and not restrictive, and the scope of the invention is defined by the appended claims, which may be modified in any manner within the scope of the invention.
