Description
Technical Field
[0001] The utility model relates to the technical field of toilets, and more specifically to a single-hole washing and flushing toilet. Background Art
[0002] Toilets can be divided into two types: split toilets and one-piece toilets. Generally, split toilets take up more space, while one-piece toilets take up less space. With the development of technology, smart toilets have emerged. Smart toilets originated in the United States and are used for medical and elderly care. They were originally equipped with warm water cleaning functions. Later, sanitary ware companies in South Korea and Japan gradually introduced technology and began to manufacture them, adding functions such as toilet seat heating, warm water cleaning, warm air drying, and sterilization. There are generally three types of smart toilets on the market: one is a smart toilet with cleaning, heating, sterilization, etc., one is a smart toilet with automatic cover change, and the other is a smart toilet with automatic cover change and cleaning functions.
[0003] Traditional toilets are generally multi-porous washing structures or single-hole washing structures. When the single-hole washing structure is flushed, the water flow rotates in the toilet pit and washes and flushes the water. It cannot form an effective downward force and cannot effectively flush and discharge sewage, which easily leads to residual dirt in the toilet pit. The dirt in the toilet pit can only be flushed away after repeated flushing. Utility Model Content
[0004] The utility model solves the above technical problems through a water flow conversion part arranged in the toilet pit, and provides a single-hole washing and flushing toilet, which can effectively flush and discharge sewage and flush away dirt.
[0005] The technical solution of the utility model is: a single-hole washing and flushing toilet, wherein the toilet is composed of a water tank and a seat head, wherein the seat head includes a toilet pit and a shell, a flushing port is provided at the upper part of the toilet pit, and a sewage outlet is provided at the bottom of the toilet pit;
[0006] The toilet pit is provided with a concave water flow conversion part, and the water flow conversion part is divided into a shallow water area and a deep water area from top to bottom in the height direction of the toilet pit.
[0007] In the utility model, the toilet pit is designed with a funnel-shaped curved surface as a whole, and an inwardly concave water flow conversion part is provided in the toilet pit. The water flow conversion part is inclined and concave from top to bottom as a whole, and is shallow at the top and deep at the bottom. The upper part is a shallow water area, and the lower part is a deep water area.
[0008] The water flow conversion part, which is shallow at the top and deep at the bottom, is provided with a double-layer drop. When flushing, the water flows in a rotation and washes in the toilet pit. When the washing water passes through the water flow conversion part, a part of the water flow changes direction through the water flow conversion part and flows to the bottom of the pit. This diversion exists throughout the entire flushing process (the water flow conversion part is inclined and concave from top to bottom, shallow at the top and deep at the bottom, and is provided with a double-layer drop), thereby forming a continuous water flow pressure on the bottom of the pit, and then flushing away the excrement, forming an effective flushing and sewage discharge. On the other hand, when the washing water passes through the water flow conversion part, the water at the upper part of the water flow passes through the shallow water area and continues to rotate forward to wash, forming the washing water of the toilet pit, washing and discharging the toilet pit. The effect of this diversion is continuous and gentle, so it has a certain mute effect.
[0009] Further preferably, the upper part of the toilet pit includes a water flow guide wall, and the bottom of the toilet pit includes a sewage wall, which is arranged on one side of the sewage outlet;
[0010] The upper end of the water flow guide wall is connected to the toilet pit opening, and the lower end of the water flow guide wall is connected to the shallow water area; the upper end of the sewage wall is connected to the deep water area, and the lower end of the sewage wall is connected to the sewage outlet.
[0011] In the utility model, the upper end of the water flow conversion part is connected to the water flow guide wall, and the lower end is connected to the sewage wall. The water flow conversion part is inclined and concave from top to bottom as a whole, with shallow water on the top and deep water on the bottom. The water flow conversion part is inclined and concave from top to bottom as a whole, with shallow water on the top and deep water on the bottom. The upper part is a shallow water area, and the lower part is a deep water area. The water flow conversion part with shallow water on the top and deep water on the bottom is provided with a double-layer drop.
[0012] Further preferably, the shallow water area includes a shallow water area bottom and a shallow water area side wall, the shallow water area bottom is connected to the water flow guide wall, and the shallow water area side wall surrounds to form a shallow water area. The deep water area includes a deep water area bottom and a deep water area side wall, one end of the deep water area bottom is connected to the shallow water area bottom, and the other end is connected to the sewage wall; the deep water area side wall surrounds to form a deep water area.
[0013] In the utility model, when flushing, water flows out from the flushing port, and performs washing and flushing along the toilet pit outside the water flow conversion portion. When the water flows through the water flow conversion portion, because the water flow conversion portion is shallow at the top and deep at the bottom, when the water flows through the shallow water area, the water flow is greater than the height of the shallow water area, a part of the water flow is converted into downward flushing water, and a part of the water flow continues to move forward to form washing water. When the water flows through the deep water area, downward flushing water is formed through the side wall of the water flow conversion portion.
[0014] Specifically, the inclination angle of the deep water area is greater than the inclination angle of the shallow water area.
[0015] Furthermore, a water retaining part is provided in the opposite direction of the water flow conversion part, and the water retaining part, the water flow conversion part, the water flow guide wall, the sewage discharge wall, etc. together constitute the toilet pit.
[0016] Furthermore, the toilet pit is provided with a flushing track along the direction of water flow from the flushing port, and the flushing track guides the water flow output from the flushing port.
[0017] Specifically, the toilet pit is an integrated structure, so that the structural strength of the entire toilet pit is stronger. The toilet pit is designed as a funnel-shaped curved surface.
[0018] Compared with the prior art, the beneficial effects are: the utility model is provided with a water flow conversion part, which is shallow at the top and deep at the bottom, and a double-layer drop is arranged at the front end of the bottom of the toilet pit, so that a part of the water flow formed by the single-hole flushing changes direction when encountering the drop at the front end and flows to the bottom of the pit. This diversion exists throughout the entire flushing process, thereby forming a continuous water flow pressure on the bottom of the pit, and then flushing away the excrement, forming an effective flushing and sewage discharge.
[0019] On the other hand, the diversion effect is continuous and gentle, so it has a certain quieting effect.

[0034] Example 1
[0035] like Figure 1-8 As shown, a single-hole flush toilet, wherein the toilet is composed of a water tank and a seat head, wherein the seat head includes a toilet pit 1 and a shell, a flush port 2 is provided at the upper part of the toilet pit 1, and a sewage outlet 3 is provided at the bottom of the toilet pit 1;
[0036] The toilet pit 1 is provided with a concave water flow conversion portion 4 , and the water flow conversion portion 4 is divided into a shallow water area 41 and a deep water area 42 from top to bottom in the height direction of the toilet pit 1 .
[0037] In this embodiment, the toilet pit 1 is designed in a funnel shape as a whole, and a water flow conversion part 4 is provided in the toilet pit 1 along the flushing direction of the water flow, which is concave toward the front end of the toilet pit wall. The water flow conversion part 4 is inclined and concave from top to bottom as a whole, shallow at the top and deep at the bottom, the upper part is a shallow water area 41, and the lower part is a deep water area 42. It should be noted that the front end of the toilet pit wall and the rear end of the toilet pit wall are in opposite directions, the rear end of the toilet pit wall is close to the toilet water tank, and the front end of the toilet pit wall is far away from the toilet water tank, and the water flow conversion part 4 is located at the front end of the toilet pit wall.
[0038] Furthermore, the shallow-upper-deep-lower water flow conversion part 4 is provided with a double-layer drop at the front end of the toilet pit wall at the bottom of the toilet pit, so that a part of the water flow formed by the single-hole flushing will change direction when encountering the drop at the front end of the toilet pit wall and flow to the bottom of the pit. This diversion exists throughout the entire flushing process, thereby forming a continuous water flow pressure on the bottom of the pit, thereby flushing away the excrement, forming an effective flushing and sewage discharge. On the other hand, the effect of the diversion is continuous and gentle, so it has a certain mute effect.
[0039] Further preferably, the upper part of the toilet pit 1 includes a water flow guide wall 5, and the bottom of the toilet pit 1 includes a sewage wall 7, and the sewage wall 7 is arranged on one side of the sewage outlet 3;
[0040] The upper end of the water flow guide wall 5 is connected to the opening of the toilet pit 1, and the lower end of the water flow guide wall 5 is connected to the shallow water area 41; the upper end of the sewage wall 7 is connected to the deep water area 42, and the lower end of the sewage wall 7 is connected to the sewage outlet 3.
[0041] In this embodiment, the upper end of the water flow conversion part 4 is connected to the water flow guide wall 5, and the lower end is connected to the sewage discharge wall 7. The water flow conversion part 4 is inclined and concave from top to bottom as a whole, and is shallow at the top and deep at the bottom.
[0042] More specifically, the shallow water area 41 includes a shallow water area nest bottom 410 and a shallow water area side wall 411, the shallow water area nest bottom 410 is connected to the water flow guide wall 5, and the shallow water area side wall 411 surrounds the shallow water area 41. The deep water area 42 includes a deep water area nest bottom 420 and a deep water area side wall 421, one end of the deep water area nest bottom 420 is connected to the shallow water area nest bottom 410, and the other end is connected to the sewage wall 7; the deep water area side wall 421 surrounds the deep water area 42.
[0043] In this embodiment, when flushing, the water flows out from the flushing port 2, and is used for washing and flushing along the toilet pit outside the water flow conversion part 4. When the water flows through the water flow conversion part 4, because the water flow conversion part 4 is shallow at the top and deep at the bottom, when the water flows through the shallow water area 41, the water flow is greater than the height of the shallow water area 41. Part of the water flow is converted into downward flushing water, and part of the water flow continues forward to form washing water. When the water flows through the deep water area 42, downward flushing water is formed through the side wall of the water flow conversion part 4.
[0044] Specifically, the inclination angle of the deep water area 42 is greater than the inclination angle of the shallow water area 41 .
[0045] In this embodiment, the main function of the shallow water area 41 is that when the water flow is greater than the height of the shallow water area 41, part of the water flow is converted into downward flushing water, and part of the water flow continues forward to form washing water, thereby forming two water flows, which respectively play the role of downward flushing and washing.
[0046] The main function of the deep water area 42 is that when the water flows through the deep water area 42, it forms a downward flush through the side wall of the water flow conversion part 4. It forms a continuous water flow pressure on the bottom of the nest, thereby flushing away the excrement, forming an effective flushing and sewage discharge.
[0047] Specifically, a water retaining portion 6 is provided in the opposite direction of the water flow conversion portion 4. The water retaining portion 6, the water flow conversion portion 4, the water flow guide wall 5, the sewage discharge wall 7, etc. together constitute the toilet pit 1.
[0048] The toilet pit 1 is provided with a flushing track 8 along the direction of water flow of the flushing port 2. The toilet pit 1 is an integrated structure. The flushing track 8 guides the water flow output from the flushing port 2. The integrated structure makes the structural strength of the entire toilet pit stronger.
[0049] It should be noted that, in this embodiment, the opening of the toilet pit 1 is rectangular with four rounded corners. The outer contour of the shallow water area 41 is a long semi-elliptical structure along the toilet pit wall.
[0050] The working principle of this embodiment is as follows:
[0051] like Figure 1-8 As shown, the flushing water flow is Figure 7-8 In the direction of the middle arrow, water flows out of the flushing port 2, flows along the flushing track 8 and the water guide wall 5, and cleans and flushes the toilet bowl.
[0052] When the water flows through the water flow conversion part 4, because the water flow conversion part 4 is shallow at the top and deep at the bottom, when the water flows through the shallow water area 41, the water flow is greater than the height of the shallow water area 41, a part of the water flow is converted into downwash water, and a part of the water flow continues forward to form washing water. When the water flows through the deep water area 42, downwash water is formed through the side wall of the water flow conversion part 4.
[0053] Finally, the water flows along the sewage wall 7 and is discharged from the sewage outlet 3 outside the toilet.
[0054] In this embodiment, the water flow conversion part 4, which is shallow at the top and deep at the bottom, is provided with a double-layer drop. When flushing, the water flows in the toilet pit and washes in rotation. When the washing water passes through the water flow conversion part 4, a part of the water flows through the water flow conversion part and changes direction, and flows to the bottom of the pit. This diversion exists throughout the entire flushing process (the water flow conversion part is inclined and concave from top to bottom, shallow at the top and deep at the bottom, and has a double-layer drop), thereby forming a continuous water flow pressure on the bottom of the pit, and then flushing away the excrement, forming an effective flushing and sewage discharge. On the other hand, when the washing water passes through the water flow conversion part, the water at the upper part of the water flow passes through the shallow water area and continues to rotate forward to wash, forming the washing water of the toilet pit, washing and discharging the toilet pit. The effect of this diversion is continuous and gentle, so it has a certain mute effect.
