Description

WATER-SAVING EASY-TO-CLEAN TOILET WITH THIN CONDUIT

TECHNICAL FIELD

The present invention relates to a rimless toilet that comprises one basin and that aims for discharging the water being used for cleaning purposes through the discharge port and subsequently, through the sewage drain by ensuring that said water being used for cleaning purposes and flowing through the water inlet is utilized in a water-saving manner.

The present invention particularly relates to a rimless toilet that conveys the water circulation which is required for the cleaning of the basin to all inner surfaces in a uniform flow, thereby ensuring a water-saving, sanitary cleaning.

STATE OF THE ART

Today, toilets with closets are widely used since they provide a more aesthetic appearance and are more comfortable to use when compared to squatting-type toilets. Particularly, sitting-type toilets with closets are usually preferred by people who have health issues in their knees, waists or in various joints and/or by people who are overweight or who have difficulties in squatting after undergoing an operation.

In general, sitting-type toilets include two fundamental components which are reservoir (water tank) and toilet. It is desired that water discharged from the water tank after usage cleans the toilet's basin. In the state of the art, rims called closed or open rings are being utilized so that water that is discharged from the water tank by means of a button or pull cord may clean visible portions of the toilet's basin. Although discharged water may clean the toilet's basin by means of these rims, said rims through which water flows may become dirty in time and since they are quite difficult to reach, these rims cannot be cleaned properly and with ease and thus optimum hygiene cannot be achieved.

Another technique known in the state of the art involves rimless toilets in which abovementioned rims that provide the water flow for the cleaning of toilet's basin and that are difficult to clean are not utilized. In rimless toilets, however, there are certain difficulties in terms of guiding the water flow which results in using larger amounts of water for cleaning the toilet's basin. However, when it is desired to save water, all surfaces of the toilet's basin cannot be cleaned hygienically.

As a consequence of searches conducted in the literature, various embodiments related to above mentioned toilet embodiments can be observed. One of these embodiments is the utility model bearing the application number of TR2015/06978 filed under the title of "Water- Saving Easy-To-Clean Toilet". Said utility model comprises an inclined water delivery channel of which starting point is narrower when compared to its ending point for the water flowing through the clean water inlet channel with pressure. U.S.A. patent application numbered US20162S7668 and titled "Water Closet Device" may be given as another example to toilet cleaning.

Consequently, the present need towards a rimless toilet that conveys the water circulation which is required for the cleaning of the basin to all inner surfaces in a uniform flow, thereby ensuring a water-saving, sanitary cleaning, as well as the inadequacy of available solutions necessitated making an improvement in the related technical field.

OBJECTS OF THE INVENTION

The present invention relates to a water-saving rimless toilet that is capable of meeting abovementioned requirements, that can eliminate potential disadvantages, and that brings further advantages. The main object of the inventive water-saving rimless toilet is to ensure that the cleaning of the toilet basin is performed in a water-saving manner. Water coming from the reservoir by means of the water conduit is entirely distributed inside the basin and as the water circulation gets completed, it is ensured that cleaning of the basin is carried out with the minimum amount of water. Another object of the present invention is to provide a water-saving rimless toilet that does not comprise a channel system inside the toilet so that the cleaning process can be performed hygienically. Since the inventive toilet does not comprise any channel system that is closed or that cannot be cleaned, hygienic cleaning can be readily carried out. A brush, a cleaning rag or any other cleaning element can be swabbed easily on the surface of the basin and the inventive toilet does not comprise any surfaces that are inaccessible by said cleaning elements.

Another object of the present invention is to provide a water-saving rimless toilet that while it meets users' desires in terms of cleaning, its structure does not disrupt an aesthetical framework. Water conduit is designed to be tangential to the basin, and in a manner that it will not cause any disruptions in the aesthetic structure.

In order to achieve abovementioned objects in the most general sense, a rimless toilet has been developed which aims for discharging the water being used for cleaning purposes through the discharge port and subsequently, through the sewage drain by ensuring that said cleaning water flowing through the water inlet is used in a water-saving manner. Said rimless toilet comprises; at least one water conduit that is tangentially formed on the surface of said basin and that distributes water to the entire area of the basin including the front portion, and at least one inlet gap that remains between the water inlet and the limiting screen positioned in front of the water inlet, and which ensures that water flows in a uniform manner and that circulation reaches to the front portion by means of guiding water to the water conduit.

Structural and characteristic features of the present invention as well as all advantages thereof will be understood more clearly by means of the figures given below and by the detailed description that is provided by making references to the figures, therefore the evaluation of the present invention should be carried out by taking these figures and the detailed description into account.

DETAILED DESCRIPTION OF THE INVENTION A rimless toilet (10) has been developed which aims for discharging the water being used for cleaning purposes through the discharge port (21) and subsequently, through the sewage drain (20) by ensuring that said cleaning water flowing through the water inlet (12) is used in a water-saving manner within the basin (11) comprised therein. Rimless toilet (10) developed for this purpose basically comprises; at least one water conduit (15) that is tangentially formed on the surface of said basin (11) and that distributes water to the entire area of the basin (11) including the front portion, and at least one inlet gap (14) that remains between the water inlet (12) and the limiting screen (13) positioned in front of the water inlet (12), and which ensures that water flows in a uniform manner and that circulation reaches to the front portion (11) by means of guiding water to the water conduit (15). Figure 1 provides the lateral section view of the inventive toilet (10). Water flows into the basin (11) through the water inlet (12), hits to the limiting screen (13) and thus, it is guided towards the water conduit (15) through the inlet gap (14). In the preferred embodiment of the present invention, the water inlet (12) is designed to be in a vertical cylindrical structure in which the inlet diameter is 55 mm, its length ranges between 25 mm to 30 mm and its outlet diameter in 45 mm. Thus, water flowing through the water inlet (12) gathers momentum and picks up speed with the contraction effect at the outlet. Figure 4 provides the front section view of the inventive toilet (10). Since the bottom edge (13b) of the limiting screen (13) is located at a position lower than the water inlet axis (y), it guides a fair amount of water flowing through the water inlet (12) tangential to the rear portion of the basin (11) so that said area can be cleaned. Water being guided towards the water conduit (15) advances inside the toilet's basin (11) along the water conduit (15) in a manner in which the water will not overflow from the upper surface (16) of the toilet (10). Water which advances tangential to the basin (11) along the water conduit (15) under the effects of pressure and acceleration, ensures that the water circulation which will clean all surfaces of the basin (11) gets completed, since the final depth (15b) is in a smaller value when compared to the initial depth (15a).

Figures 2 and 3 provide the top view of the inventive toilet (10) in two different designs in which the inventive toilet comprises water conduit (15). Amounts of water circulating inside the toilet's (10) basin (11) of different designs need to be changed due to differences in size. In toilets (10) having a smaller basin (11), when the final depth (15b) of the water conduit (15) obtains a zero value on the front portion (11a), overflowing of water from the basin's (11) upper surface (16) can be prevented as it can be seen in Figure 3. However in toilets (10) having larger basins (11), because of the fact that the amount of water to be guided towards the front portion (11a) of the basin (11) will be larger, final depth (15b) of the water conduit (15) assumes a value different than zero and continues circulating the water as it can be seen in Figure 2.

Figure 5 provides the perspective view of the inventive toilet (10). The fact that vertical width of the limiting screen (13) on side edges (13a) is shorter when compared to the bottom edge (13b) ensures that water is guided tangential to the basin (11) surface in a manner in which water flowing through the water inlet (12) will not be prevented from reaching to the water conduit (15). Furthermore, the fact that the water conduit (15) has a slope of 0 or a negative degree angle from the initial depth (15a) towards the final depth (15b) prevents water overflowing from the upper surface (16) of the basin (11) during its circulation inside the basin (11). The scope of protection of the present application is defined in the appended patent claims and therefore, the present invention cannot be confined to above-given disclosure provided for illustrative purposes only, moreover, it is obvious that a person who is skilled in the art can set forth the novelty revealed in the present invention by using similar embodiments and/or can implement this embodiment in different fields that are used in the related technical field, and that have similar purposes. Therefore, it is quite apparent that suchlike embodiments will lack the novelty criteria and especially the criteria required for surpassing the state of the art.
