Description

Technical Field

[0001] The invention belongs to the technical field of toilets and relates to an intelligent toilet flushing structure. Background Art

[0002] With the improvement of people's living standards, toilets have gradually become an indispensable sanitary appliance in people's lives, and the application of toilets has become very common. At the same time, smart toilets with functions such as warm water washing and warm air drying are also increasingly used in daily life.

[0003] Existing smart toilets, for example, Chinese patent literature discloses a new instant hot smart one-piece toilet [application number: 201320320891.X; authorization announcement number: CN203270742], which includes a cleaning water system, a flushing water system, an air system and an automatic flip cover system. The automatic flip cover system is provided with a rear base, the cleaning water system and the air system are both installed on the rear base, and the flushing water system is installed in the rear base.

[0004] In a toilet with this structure, the cleaning water system is connected to the water inlet tee, and the cleaning water system includes a small water tank, in which hot water and cold water are mixed. The small water tank directly connects the water inlet tee to the water drying nozzle. In order to prevent the siphon phenomenon, the toilet with this structure adopts the method of reducing the water inlet gap, but the siphon phenomenon still exists. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose an intelligent toilet flushing structure, the technical problem to be solved is how to prevent the siphon phenomenon from occurring in the flushing structure.

[0006] The objective of the present invention can be achieved through the following technical solutions: an intelligent toilet flushing structure, comprising a mounting frame fixed in a toilet body, characterized in that the flushing structure also includes a water tank, a first driver and a second driver arranged in the mounting frame, the water inlet end of the first driver is connected to the outside, the water outlet end of the first driver is connected to the top of the water tank, the water inlet end of the second driver is connected to the bottom of the water tank, the water outlet end of the second driver is used to connect to a flushing pipe, and an overflow port is opened on the side of the box body, and along the vertical direction, the overflow port is located between the water outlet end of the first driver and the water inlet end of the second driver.

[0007] When working, the first driver sends flushing water into the water tank, and the flushing water enters from the top of the water tank. The second driver extracts the flushing water in the water tank to flush the human body. During this process, the first driver will continue to fill the water tank with water. The overflow port is set so that the water in the water tank that exceeds the overflow port will be discharged from the overflow port, so that the water surface in the water tank will not be connected to the water outlet end of the first driver, that is, the water is disconnected in the water tank, and there is air in the space between the water surface in the water tank and the top of the water tank. The air acts as a partition to achieve physical anti-siphonage of the flushing structure.

[0008] In the above-mentioned intelligent toilet flushing structure, the inner wall of the water tank has a step-shaped buffer portion, and the buffer portion is located directly below the water inlet end of the water tank. When the flushing water falls, the flushing water flows along the buffer portion. Since the buffer portion is in a step-shaped shape, the buffer portion plays a role in slowing down and draining the flushing water, preventing the flushing water from splashing, and playing a buffering role for the flushing water, which has a silent effect, thereby reducing the noise emitted by the flushing structure and improving the comfort of the user.

[0009] In the above-mentioned intelligent toilet flushing structure, the buffer part includes a plurality of step surfaces, and the edge of the uppermost step surface is provided with a plurality of baffle bars protruding upward, and a water-passing gap is provided between two adjacent baffle bars. The baffle bars play a buffering role, so that the flushing water flowing to the uppermost step surface will not fall to the second step surface too quickly, thereby reducing noise; the water-passing gap is provided so that water can flow down from the buffer part, and at the same time, when the amount of flushing water is large, it can flow over the baffle bars to the next step surface.

[0010] In the above-mentioned intelligent toilet flushing structure, the water tank includes a tank cover located at the top, the tank cover has a connecting protrusion which is upwardly protruding and has a hollow interior, the water inlet end of the water tank is located at the top of the connecting protrusion, the top of the connecting protrusion has a blocking portion which is directly opposite to the water inlet end of the water tank, the bottom of the connecting protrusion has an inclined drainage portion, the blocking portion is located directly above the drainage portion, and the water outlet end of the drainage portion is located directly above the buffer portion. The water inlet end of the water tank is connected with the water outlet end of the first driver. The blocking part blocks the flushing water so that the flushing water will definitely fall onto the drainage part. The drainage part is inclined, and the flushing water falls along the drainage part to the buffer part. The flushing water flows smoothly and reduces noise. The connecting protrusion is a protrusion on a part of the box cover. It is not large in size. After the flushing water enters, it will fill the entire cavity and the noise is small, thereby reducing the noise of the entire flushing structure. At the same time, the setting of the connecting protrusion makes the water outlet end of the first driver located above the box cover, further expanding the distance, increasing the space of the anti-siphon partition, and realizing physical anti-siphonage of the flushing structure.

[0011] In the above-mentioned intelligent toilet flushing structure, the drainage part includes an inclined bottom plate and a pair of drainage strips protruding from the bottom plate, the bottom plate and the pair of drainage strips enclose a drainage groove, the water outlet end of the drainage groove is located directly above the buffer part, the top of the connecting protrusion has a concave guide groove, the guide groove is located between the water inlet end of the water tank and the blocking part and the guide groove is arranged along the axial direction of the water inlet end of the water tank, and the guide groove is located directly above the guide groove. The arrangement of the drainage strip, the drainage groove and the guide groove plays a role in draining the flushing water, ensuring that the flushing water flows in the set direction, and the flushing water flows smoothly, thereby reducing the noise of the flushing structure.

[0012] In the above-mentioned intelligent toilet flushing structure, the water tank includes a box body, and the box body and the mounting frame are an integrated structure. The integrated structure is highly firm, and the box body can be processed while manufacturing the mounting frame, and only one mold is needed, which reduces the processing cost; at the same time, the installation of the water tank is avoided, and the working hours are reduced.

[0013] In the above-mentioned intelligent toilet flushing structure, along the horizontal direction, the cross-sectional area of ​​the water tank is 1 / 20-1 / 5 of the cross-sectional area of ​​the mounting frame. This structure allows the water tank to be a small water tank, which will not occupy too much installation position, thereby not affecting the installation of the intelligent cover, so that the toilet can meet the installation requirements of ordinary intelligent covers and has good versatility.

[0014] In the above-mentioned intelligent toilet flushing structure, a floating rod that can float up and down is provided in the water tank, and the floating rod has a plurality of protruding floating parts, and the top of the floating rod has a protruding limiting part, and the top of the floating rod passes through the top of the water tank and the limiting part can be against the water tank. The setting of the floating rod and the floating part can detect the water level in the water tank, thereby achieving precise control to ensure clean flushing, and also controlling the minimum water level of the water tank to prevent the intelligent toilet from instantaneously heating the water tank and causing dry burning or half burning.

[0015] In the above-mentioned intelligent toilet flushing structure, the outer wall of the water tank is concavely arranged in a stepped shape, and the concave part matches the buffer part. This structure can effectively reduce the use of raw materials and reduce costs; at the same time, the mounting frame can better match the main body of the toilet, and improve the installation firmness of the mounting frame.

[0016] In the above-mentioned intelligent toilet flushing structure, the first driver and the second driver are both arranged outside the water tank, and along the vertical direction, the second driver is located above the first driver, so as to reasonably utilize the space.

[0017] In the above-mentioned intelligent toilet flushing structure, the first driver is a solenoid valve, and the second driver is a water pump. The first driver turns the flushing water into a constant flow of water, and the flushing force can be increased by the second driver.

[0018] Compared with the prior art, the intelligent toilet flushing structure provided by the present invention has the following advantages:

[0019] 1. Due to the setting of the overflow port, the water in the water tank of the flushing structure will not be connected to the water outlet end of the first driver, that is, the water is disconnected in the water tank, and there is air in the space between the water surface in the water tank and the top of the water tank. The air acts as a partition to achieve physical anti-siphonage of the flushing structure.

[0020] 2. The setting of the buffer part and the connecting protrusion of the flushing structure can effectively buffer the flushing water entering the water tank, prevent the flushing water from splashing, and play a silent role, thereby reducing the noise emitted by the flushing structure and improving the comfort of the user.

[0021] 3. The box body and the mounting frame of this flushing structure are an integrated structure. The water tank is a small water tank and will not occupy too much installation position, thereby not affecting the installation of the smart cover. This allows the toilet to meet the installation requirements of ordinary smart covers and has good versatility. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] like Figure 1 , Figure 2 As shown, the smart toilet includes a main body and a flushing structure arranged in the main body, and the flushing structure includes a mounting frame 1, a water tank 2, a first drive 3, a second drive 4 and a float rod 5.

[0030] like Figure 3 As shown, the water tank 2 includes a tank cover 22 and a tank body 27. The tank body 27 and the mounting frame 1 are an integrated structure. The tank body 27 and the mounting frame 1 are formed at one time by injection molding. The tank cover 22 is fixed to the top of the tank body 27 by fasteners such as bolts. In this embodiment, along the horizontal direction, the cross-sectional area of ​​the water tank 2 is 1 / 10 of the cross-sectional area of ​​the mounting frame 1. In actual production, the cross-sectional area of ​​the water tank 2 can be 1 / 20 or 1 / 5 of the cross-sectional area of ​​the mounting frame 1.

[0031] In this embodiment, the first driver 3 is a solenoid valve, and the second driver 4 is a water pump. In actual production, the first driver 3 can be a water pump, and the second driver 4 can be a solenoid valve. The first driver 3 and the second driver 4 are both arranged outside the water tank 2. In the vertical direction, the second driver 4 is located above the first driver 3. The water inlet end of the first driver 3 is connected to the outside world for connecting tap water. The water outlet end of the first driver 3 is connected to the top of the water tank 2, and the water inlet end of the second driver 4 is connected to the bottom of the water tank 2. The water outlet end of the second driver 4 is used to connect to the flushing pipe.

[0032] The inner wall of the water tank 2 is provided with a step-shaped buffer portion 21, and the buffer portion 21 is located directly below the water inlet end of the water tank 2. The outer wall of the water tank 2 is recessed in a step-shaped manner, and the recessed portion matches the buffer portion 21. In this embodiment, the buffer portion 21 includes two step surfaces 211, and the edge of the uppermost step surface 211 is provided with two upwardly protruding baffle bars 212, and a water-passing gap 213 is provided between two adjacent baffle bars 212. In actual production, the number of step surfaces 211 can be three or four, and the number of baffle bars 212 can be three or four.

[0033] like Figure 4 As shown, the tank cover 22 has a connection protrusion 23 which is upwardly protruding and has a hollow interior. The water inlet end of the water tank 2 is located at the top of the connection protrusion 23. Figure 5As shown, the top of the connecting protrusion 23 has a blocking portion 24 arranged opposite to the water inlet end of the water tank 2, and the top of the connecting protrusion 23 has a concave guide groove 26, which is located between the water inlet end of the water tank 2 and the blocking portion 24 and is arranged along the axial direction of the water inlet end of the water tank 2. The bottom of the connecting protrusion 23 has an inclined drainage portion 25, which includes an inclined bottom plate 251 and a pair of drainage strips 252 protrudingly arranged on the bottom plate 251, and the bottom plate 251 and the pair of drainage strips 252 surround a drainage groove 253, the blocking portion 24 is located directly above the drainage portion 25, the guide groove 26 is located directly above the drainage groove 253, and the water outlet end of the drainage portion 25 is located directly above the buffer portion 21. Specifically, the water outlet end of the drainage groove 253 is located directly above the buffer portion 21.

[0034] The water tank 2 is provided with a floating rod 5 that can float up and down. In this embodiment, the floating rod 5 has two protruding floating parts 51. In actual production, the number of the floating parts 51 can be three or four. The top of the floating rod 5 has a protruding limiting part 52. The top of the floating rod 5 passes through the top of the water tank 2 and the limiting part 52 can abut against the water tank 2.

[0035] When working, the first driver 3 is connected to tap water, and the tap water is turned on and flows to the first driver 3. The first driver 3 is turned on, and the water flow rate becomes a constant flow of water after entering the first driver 3. The flushing water enters the guide groove 26 through the water inlet end at the connecting protrusion 23 and hits the blocking part 24. Then the flushing water fills the entire cavity in the connecting protrusion 23 and flows to the buffer part 21 along the drainage part 25, and then gradually flows into the water tank 2 through the water gap 213. The float rod 5 moves up due to the buoyancy of the flushing water. After the controller senses the signal, it will issue a water stop command, and the first driver 3 will close the water inlet. At this time, the height of the water stored in the water tank 2 is the working water level of the water tank 2. When flushing is required, the second driver 4 works to pump water from the bottom of the water tank 2. As the water level drops, the float rod 5 will move down. After the controller senses the signal, it will issue a water inlet command, and the first driver 3 will start to replenish the water tank 2. This cycle is repeated to complete flushing. In the above process, when the water in the water tank 2 exceeds the overflow port 28 , the water will flow out from the overflow port 28 .

[0036] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0037] Although the present invention uses more terms such as mounting frame 1, water tank 2, buffer part 21, step surface 211, baffle strip 212, water gap 213, box cover 22, connecting protrusion 23, blocking part 24, drainage part 25, bottom plate 251, drainage strip 252, drainage groove 253, guide groove 26, box body 27, overflow port 28, first driver 3, second driver 4, floating rod 5, floating part 51, and limiting part 52, the possibility of using other terms is not excluded.
