This invention generally relates to portable toilets and toilets for vehicles to travel. More specifically, the invention relates to a toilet including a drain node, which is a desirable characteristic of having the IPA, relates to the present invention, is typically used pump, driven manually or by a battery, for pumping fresh water to drain from the water source to drain into the toilet. Hand pumps are low cost, and they are often used bottles. When using the pump, operating on the principle of furs, the user usually needs to apply to the bellows to actuate the pump power, is approximately equal to 16 kg If the power is supplied in an excessive amount of or too vigorously, the water is discharged to drain through the discharge nozzle and splashed out of the toilet. If the bellows is attached to insufficient power, drain it turns out to be unsatisfactory. While hand pumps can be considered suitable for some users, persons with physical disabilities, the elderly and the young, as a rule, do not have enough strength for handling bellows pump. For such users have developed the drain nodes with a power drive.

Electric drain nodes or nodes with a power drive require applications to leading means less effort than hand pumps, and allow for multiple uniform hydration and a more thorough draining in unitymedia toilet, includes drain node with a power drive.

One of the reasons for the need to obtain sufficient power drain is that the exhaust nozzle is usually included shutoff valve to prevent leakage of water to drain from the water source. In shut-off valves are normally used spiral or push spring, introducing the valve disc in sealed engagement with the valve seat. Due to the use of a spring, the force required for opening the shut-off valve, is less than the force required to hold the valve in the open position. Thus, the force required to hold the valve in open position, increases with the deviation of the valve disc from the valve seat.

Toilets with manual discharge device such restriction is not essential, because they are equally great force required for the initial opening of the shutoff valve and hold it in open position until the completion of discharge. However, this resistance often reaches values, which leads to rapid battery depletion or exhaustion of the drive energy drain node. Thus, one goal, when creating a drain node with a power drive, is to use as less energy when YH nodes with power-driven shutoff valve manual valve, made in spill site so that it works regardless of the strength of the pressure required to actuate the proper drainage. This again causes a problem for the elderly, minors and other persons who, in General, do not have enough physical strength or ability to control the mechanical part of the pump.

This aforementioned manual valve in the normal position remains closed and is part of the pump. The valve is opened manually at the beginning of a discharge caused by movement of the same leading tools, which closes the switch, which, in turn, causes a discharge with power assistance. However, this valve complicates the drain node and requires the exclusion of the shutoff valve of the device of the toilet, which otherwise remains identical, which also increases manufacturing costs.

Taking into consideration the above-mentioned disadvantages, a principal object of the present invention is to provide a toilet that requires reduced power drain with manual pump and pump drive power.

Another objective of the present invention is the use of restricting the flow through the shutoff valve in the toilet, which is equally mouasher invention is to provide a toilet which has a superior washing action, the effective use of the water to drain and which provides a more efficient source of energy, if it is equipped with a pump with a power drive.

Another objective of the present invention is to provide a toilet having a shutoff valve, requiring less effort to hold it in the open position than its initial opening.

Another object of the present invention is to provide a toilet shut-off valve, which is held in the closed position, not spring.

Another objective of the present invention is to provide a toilet shut-off valve, in which to maintain the closed position of the valve is applied to the magnet.

Brief description of the invention

The present invention relates to a new and improved toilet for vehicles to travel, which requires less power drain than the design of the prior art. The toilet includes a section for the seat with toilet bowl having a bottom outlet. The toilet also includes a water source to drain, such as a camera for the water to drain from which podeschi, with power drive or other pumping means delivers fresh water to drain from the water source to drain through the drain pipe and the exhaust nozzle in the toilet. Pumping means delivers water to drain under the pressure and flow rate sufficient to open the shutoff valve in the exhaust line and which provide good discharge with 100% coverage of water to drain the surface of the toilet bowl.

Shut-off valve prevents leaks, spills or inadvertent omission of the otherwise water to drain into the toilet. Through the valve housing of the valve and valve seat formed in the passage, restricting the opening through which must leaking water to drain. Inside the entrance a movably mounted plunger. The plunger is adapted for watertight engagement with the valve seat and to move between a position in which it is seated on the valve seat (preventing the flow of water to drain through the valve Assembly) and a position in which it is separated from the valve seat (allowing the flow of water to drain through the valve site).

Instead of the usual pressure spring, which is used to podpruzhineny drive the valve to its seat on the valve seat, the present izobreteny the way of influence on the valve, to maintain the open position of the valve requires less power than its initial opening. This characteristic makes it possible to supply the toilet as manual pumping means, and pumping means with a power drive, without the need for additional modifications to the toilet or pumping means, resulting in lower production costs.

Additional benefits and advantages of the present invention will be obvious to a person skilled in the art to which the present invention from the following description of the preferred embodiment variants of the invention and appended claims in conjunction with the accompanying drawings.

A detailed description of the preferred embodiment variants of the invention

An improved toilet corresponding to the characteristics of the present invention, generally depicted in Fig. 1 and 2 and indicated by the numeral 10. Although the toilet 10 is depicted as a portable toilet, the present invention is not limited to this and is equally applicable to reportative toilets and proportation toilets. The toilet 10 includes a section for the seat 12, which is installed with the possibility of detaching the reservoir 14 is well known in the usual way. Section for the seat 12 includes a toilet bowl 16, lying on its seat 18 and lid 20. The seat 18 and lid 20 are attached by hinges to the rear section to seat 12. The tank or chamber 22 for fresh water drain is located inside the section for the seat 12 and the camera 22 may be filled with fresh water to drain through the fill port, closed by a removable cover 24. Alternatively, the water drain may be supplied from the outside or from another source, instead of the camera 22.

The toilet bowl 16 fitted with a venting hole 26 located on the bottom of the bowl 16 so that it corresponds to a hole (not shown) in the tank 14 when these two sections set is Rania sewage 28, contained within the tank 14. When the toilet 10 is not used, the discharge opening 26 is covered by the disk or shutoff valve 30 of a different type, which can be controlled by the user of the toilet.

Manual, electric or having power drive pumping means 32 is used for pumping fresh water to drain from the water source to drain 22 into the bowl 16 to remove sewage from the toilet bowl 16. Pumping means 32 mounted on the partition for the seat 12 in facing up the hole 34, which is depicted in the right hand upper corner 36 of the section for the seat. Ring, gasket or other seal means (not shown) is used for moisture-proof seal around the opening 34 when the pumping means 32 and the section of the seat 12 are interconnected. The upper part of the pumping means 32 includes a cap 38 leading tools, which has a top wall 40 and the branching skirt 42. Glide over the body portion 44 of the cap 38 leading means is pressed to actuate the discharge device 32 and the beginning of the drain. The cap 38 leading tools are sometimes called "button for hands", as the user clicks on it with the palm of the hand.

With whom can be driven entirely by hand, and include bellows or, alternatively, a pumping means 32 may be electrically driven. Pumping means 32, shown in Fig. 2, is the latest variant. Because pumping means 32 may have one of many configurations, it is not necessary to describe here its specific details.

Regardless of the type of pumping means 32, which is supplied with the toilet 10, the tool 32 will include an inlet opening 46, through which the absorbed water to drain, and the exhaust port 48, through which the water to drain is available. With the outlet 48 is connected to the drain channel or pipe 50, which supplies water to drain to the outlet of the nozzle 52, where the water goes into the bowl 16 of the toilet 10.

More specifically, the exhaust nozzle 52 is oriented so that the water discharge is directed into the toilet bowl 16 of the toilet on its perimeter, providing hydration entire surface of the bowl. To facilitate the wetting of the entire surface of the bowl and ensure drain the entire contents of the bowl 16 through the outlet 26 into the chamber 28 for the maintenance of the sewage tank 14, the bowl 16 is equipped with a drain ledge 54. Drain the ledge 54 is located around the upper perimeter of the toilet bowl 16, promoting naparnitsa 16.

As noted above, the isolation valves were usually placed either at the outlet of the nozzle, or in line with the drain pipe to prevent the inadvertent omission of the water to drain through the pipe. Shut-off valves, as a rule, included a push spring holding the valve disc to the valve seat when the toilet was not flushed. It is obvious that with the use of a pressure spring, when the disk is pressed against the valve seat, the pressure necessary for the further deflection of the valve disc from the valve seat increases as a result of compression of the spring. In General, the force required for manual pumping means, forms a line pressure, which is sufficient for the movement of the shut-off valve in its open position. The pressure further ensures the preservation of the open valve position during the entire procedure plum.

It is not always desirable to include in the design of the toilet manual inflation. Often, the force required for manual pumping means, leads to difficulties when using the toilet individuals with physical disabilities, the elderly, those suffering from arthritis or young persons For this reason become popular pumping means with Elektricheskiye and thus, the power supply is limited. First, to ensure the work of the pumping means with the pressure levels of the water to drain, which would give a good discharge to the toilet without excessive battery discharge, shut-off valve connected to the exhaust nozzle has been removed and a pumping device should include other means that would prevent the inadvertent omission of the water to drain into the toilet.

Instead, the present invention provides for the creation of a shut-off valve 56, which can be used as a manual pumping device 32, and a pumping device having an electric or power drive, while not causing excessive discharge of the batteries last. In the manufacture of the toilet 10, the characteristics of the present invention eliminate the need for separate production lines at the plant, which would be designed specifically for the production of a pumping device 32. Additionally, and in contrast to previous practice, the present invention eliminates the need for a final quality inspection to ensure that the pumping device 32 with a power drive is not mounted in combination with a toilet 10, ilustrita 32 with its own built-in valve means. Shut-off valve 56 used in the present invention, has all the above characteristics, while requiring less effort to maintain the valve in the open position than the original opening.

As shown in Fig. 3 and 4, the portion of the shut-off valve 56 is made as a unit with the exhaust nozzle 52. Of course, the check valve 56 can be performed separately from the exhaust nozzle 52 and located totally or partially within the drain pipe 50 without departing from the principles of the present invention.

Flanges 58 secured the discharge nozzle 52 within holes (not shown) formed in the partition for the seat 12 of the toilet 10. The nozzle 52 is oriented so that the water to drain discharged from the nozzle 52 will be properly directed into the toilet. Back or from the mounting flange 58 retreats cylindrical extension or housing 60 shut-off valve 56. The channel or passage 62 formed in the housing 60 shut-off valve with a message with the passage 64, similarly formed in the exhaust nozzle 52. To the far end 66 of the housing 60 (the end remote from the exhaust nozzles 52) formed adjacent to the outer surface of the rib 68 and the collar 70, which act on the ring around the ring engages the groove 78, which separates the seal 72 on the outside of the skirt 74 and the inner skirt 80. The seal 72 is worn or placed by crimping to the far end 66 of the housing 60 so that the end part 76 of the outer skirt 74 snaps over the rib 68 and its elasticity holds the seal 72 on the housing 60. The collar 70 and the groove 78 interact, limiting the depth to which the seal 72 may be fixed to the housing 60. When installed properly, the seal 72 receives the far end 66 of the housing 60 into the groove 78, and the inner skirt 80 runs along the inner surfaces of the housing 60 in the passage 62. The inner skirt 80 ends bent radially inward protrusion of the restricting hole 81 (Fig. 4), around which there is a plot, which is referred to as a valve seat 82 of the stop valve 56.

The drain pipe 50 is also attached to the far end 66 of the housing 60 shut-off valve on top of the skirt 74 of the seal 72. To prevent inadvertent retraction of the drain pipe 50 or separating it from the far end 66 of the stop valve 56, the drain pipe 50 can be equipped with a lug 51, which will snap into place on the collar 70. To keep the drain pipe 50 of the shut-off valve 56, alternatively, may apply Homa the plunger 84 is pushed to the valve seat 82, and the passage 62 in the shut-off valve 56 is fully closed. Semicircular or hemispherical contact surface 86 formed on the plunger 84 to provide moisture-proof contact between the valve seat 82 and piston 84 when they are in the United status. Obviously, that can be used in other configurations of the contact surface 86 and a hole bounded by the valve seat 82, if they will provide a water resistant seal.

The plunger 84 is free to move in the passage 62, limited housing 60 shut-off valve 56. In the passage 62 is a valve spring 88, which in a preferred variant embodiment of the invention has the configuration of a spiral spring. One end of the valve spring 88 is in contact with narrowed, having a smaller diameter or curved part 90 of the passage 62, in General, adjacent to the passage 64 of the exhaust nozzle 52, while the opposite end of the spring valve covers 88 of the plunger 84 from the side opposite to the contact surface 86. The plunger 84 is provided with lugs 92 to prevent slippage of the plunger 82 into the spring 88. The lugs 92 to provide support for the plunger 84 of the valve spring 88.

Spring clapano be noted, that banana force generated by the valve spring 88, in General, sufficient to maintain the plunger 84 in compressed contact with the valve seat 82 so as to prevent inadvertent admission of water to drain through a check valve 56. Valve spring 88 functions as a means to ensure proper operation of the other of the primary or first loading means. This is another load on the tool is intended to ensure sealing contact between the valve seat 82 and the plunger 84, when not made of plums.

It should be noted that the passage 62 provides a tolerance for the free movement of the spring 88 in the housing 60. Loading means providing sealed contact of the plunger 84 and the valve seat 82, in General, is situated on either side of the contact surface 86 which faces towards the water, and includes a magnet 94, the pin 96 and the holder pin 98. The magnet 94 and pin 96 mounted so that they are positioned generally along the axis of the passage 62 in the housing 60 shut-off valve 56. In one variant embodiment of the present invention, the magnet 94 affixed or fastened in another way in a cylindrical recess in the contact surface 86 of the plunger 84, while the pin 96 is held in the holder stem 94. The holder 98 includes an outer ring 99, which leaves one or more, preferably, three directed radially inward of the blades 100, retaining and establishing the pin 96, preferably in the center of the ring 99 coaxially with the magnet 94. Blades 100 equidistant from each other in the opening formed by the ring 99, providing significant open spaces through which water can drain essentially to flow freely. The pin 96 may be held in the holder 98 in a variety of ways, including gluing or press-fitting.

Because the shut-off valve 56 is enabled, the magnet 94 and pin 96, which is made of metal, such as steel, it is not necessary that the valve spring 88 is provided a sealed contact between the valve seat 82 and the plunger 84. This contact is largely provided by the magnetic attraction of the magnet 94 and pin 96. The purpose of the valve spring 88 is to push the plunger 84 to the point where the magnet 94 is sufficiently close to the pin 96 so that magnetic attraction between the two elements was sufficient to provide a sealing contact with the valve seat 82 with the contact surface 86 of the plunger 84. Preferably, the magnet 94 and pin 96, version, the magnet 94 and pin 96 can be rotated so that the pin 96 is movably hold the plunger 84 and the magnet 94 is held by the holder 98. Regardless of such permutations, the shut-off valve 56 operates in the same way.

When the toilet 10, the required primary pressure water to drain to the separation of the magnet 94 and pin 96 and the plunger 84 and the valve seat 82. With this separation, as seen in Fig. 4, to maintain the open position of the shut-off valve 56 requires less pressure, because the attraction between the magnet 94 and pin 96, when their separation decreases, and because the weak force of the spring is not enough to join them. When reducing the pressure in the discharge pipe 50, the spring pushes the plunger 84 in the direction of the valve seat 82 and, ultimately, the magnetic attraction between the magnet 94 and pin 96 again causes the sealed contact between the plunger 84 and the valve seat 82.
