[0052] As Figure 1 shown, the present embodiment provides a liner self-cleaning system, which can realize automatic cleaning of the liner 210, save time and effort, and avoid bacterial growth in the liner 210. The liner self-cleaning system comprises a liner 210, a water purification tank 400, a water distribution valve 500 and a circulating water tank 600. The liner 210 is closable. The liner 210 is provided with a heating assembly 300 configured to heat the water in the liner 210. The liner 210 is also provided with a spraying structure 100. The water purification tank 400 can supply water to the spraying structure 100 or the inside of the liner 210. The water distribution valve 500 is in communication with the bottom of the liner 210. The water distribution valve 500 has two water outlets. The water distribution valve 500 can simultaneously close both water outlets or individually open any water outlet. One of the water outlets leads to an oil box 900. The water flowing out of the other water outlet can be stored in the circulating water tank 600 or flow back to the spraying structure 100. The circulating water tank 600 can also supply water to the spraying structure 100.

[0053] The aforementioned inner tank cleaning system allows users to select between two cleaning modes. When the inner tank 210 is only slightly dirty, a simple cleaning mode is used. First, steam cleaning is performed. The circulating water tank 600 is emptied, and the clean water tank 400 is filled with water. The water distribution valve 500 closes both outlets, and the clean water tank 400 supplies water to the inner tank 210. The heating element 300 operates to heat the water in the inner tank 210 into steam. The outlet leading to the oil box 900 is defined as the first outlet 532, and the other outlet is defined as the second outlet 533. The water distribution valve 500 opens the second outlet 533 separately, and the clean water tank 400 supplies water to the spray structure 100. The water then flows back to the spray structure 100 through the second outlet 533, completing one cleaning cycle. Wastewater is discharged into the circulating water tank 600 through the second outlet 533 and is then treated. When the inner tank 210 is heavily soiled, a deep cleaning mode is activated. The circulating water tank 600 and the clean water tank 400 are filled with water, cleaning agent is added to the circulating water tank 600, and the oil box 900 is emptied. The water distribution valve 500 closes both outlets, the clean water tank 400 supplies water to the inner tank 210, and the heating element 300 activates, heating the water in the inner tank 210 into steam. The circulating water tank 600 supplies water to the spray structure 100, and the steam flows through the second outlet... The water from outlet 533 flows back to the spray structure 100, performing a deep cleaning cycle. Wastewater from the deep cleaning cycle is discharged from the second outlet 533 into the circulating water tank 600. The clean water tank 400 supplies water to the spray structure 100, which then flows back through the second outlet 533 to perform a rinsing cycle. The first outlet 532 is opened, and the wastewater from the rinsing cycle flows into the oil box 900, which is then emptied. Thus, the aforementioned inner tank cleaning system, through the above settings and the switching of the three states of the water distribution valve 500, achieves automatic cleaning of the inner tank 210. It can also select the cleaning mode according to the situation, saving time and effort and preventing bacterial growth inside the inner tank 210.

[0054] Optionally, such as Figure 1 As shown, the clean water tank 400 is connected to the spray structure 100 via a first pipe 710, on which a circulation pump 810 is installed. The clean water tank 400 is also connected to the inner tank 210 via a second pipe 720, on which an inlet pump 820 is installed. A first solenoid valve 840 is installed upstream of the circulation pump 810 on the first pipe 710. It can be understood that by installing the circulation pump 810, water can enter the spray structure 100 and be pumped out of the inner tank 210, thus achieving a clean water circulation.

[0055] Optionally, such as Figure 1As shown, the second water outlet 533 is communicated with the first water line 710 between the first electromagnetic valve 840 and the circulating pump 810 through a third water line 730. It can be understood that the circulating pump 810 completes a circulating path of water from the first water line 710 into the inner container 210, to the third water line 730 and back to the first water line 710, forming a circulating cleaning during cleaning.

[0056] Optionally, the first water line 710 and the second water line 720 share a first water outlet pipe 770, and the first water outlet pipe 770 is provided with a first check valve 860 configured to allow water to flow out of the water tank 400 and prevent water from flowing into the water tank 400. By providing the first check valve 860, backflow of water into the water tank 400 is prevented, ensuring that the water in the water tank 400 is not contaminated.

[0057] Optionally, as shown, Figure 1 The third water line 730 branches to form a fourth water line 740, the fourth water line 740 branches to form a fifth water line 750 and a sixth water line 760, the fifth water line 750 and the sixth water line 760 are respectively communicated with the circulating water tank 600, the fifth water line 750 is provided with a second electromagnetic valve 850, and the sixth water line 760 is provided with a drain pump 830 configured to pump water into the circulating water tank 600. Through the above arrangement, when the cleaning program is completed, the dirty water is discharged into the circulating water tank 600 by turning on the drain pump 830.

[0058] Optionally, the sixth water line 760 is provided with a second check valve 870 configured to allow water to flow to the circulating water tank 600 and prevent water from the circulating water tank 600 to flow out of the second check valve 870; through the above arrangement, the water discharged into the circulating water tank 600 is prevented from overflowing into the fourth water line 740 and then into the circulating water line.

[0059] Optionally, as shown, Figure 2As shown, the water distribution valve 500 comprises a driving member 510, a paddle 520 and a water distribution member 530, the water distribution member 530 is connected with the body of the driving member 510 and forms an inlet 531 and two outlets, the inlet 531 is communicated with the inner container 210, the two outlets are located at the circumferential side of the water distribution member 530, the paddle 520 is connected with the output end of the driving member 510 and tightly abuts the inner wall of the water distribution member 530, the driving member 510 can drive the paddle 520 to rotate to simultaneously close the two outlets or separately open one of the two outlets. It can be understood that the output end of the driving member 510 stays at three positions, at the first position, the paddle 520 closes the first outlet 532 and the second outlet 533, at the second position, the first outlet 532 is opened and the paddle 520 only closes the second outlet 533, at the third position, the second outlet 533 is opened and the paddle 520 only closes the first outlet 532, so as to realize the switching of the three states of the water distribution valve 500.

[0060] Optionally, as shown in Figure 2 The paddle 520 comprises a sealing portion 521 and a first limiting portion 522, the sealing portion 521 is partially annular and is matched with the shape of the inner wall of the water distribution member 530, the first limiting portion 522 is connected with the side of the sealing portion 521 away from the inner wall of the water distribution member 530; the water distribution valve 500 further comprises a resilient member 540, the output end of the driving member 510 is circumferentially provided with a second limiting portion 511, one end of the resilient member 540 abuts against the output end of the driving member 510 and is limited by the second limiting portion 511, the other end of the resilient member 540 abuts against the sealing portion 521 and is limited by the first limiting portion 522. Through the above arrangement, the resilient member 540 can tightly abut the paddle 520 on the inner wall of the water distribution member 530, so as to ensure the tightness of the sealing, at the same time, the resilient member 540 is limited by the first limiting portion 522 and the second limiting portion 511, so as to prevent the resilient member 540 from running out of position during use. In the embodiment, the first limiting portion 522 is annular and the second limiting portion 511 is cylindrical, in other embodiments, the two can be interchanged or both are annular or both are cylindrical, which are matched with the shape of the end of the resilient member 540, which is not limited herein.

[0061] In an optional embodiment, one of the extreme cases, as shown in Figure 3 In the embodiment, the corresponding central angle of the paddle 520 is obtuse, of course, on this basis, the central angle of the paddle 520 can be appropriately increased.

[0062] In another optional embodiment, another extreme case, as shown inFigure 4 As shown, when the dial 520 covers the first water outlet 532 and the second water outlet 533 at the same time, i.e. in the closed state, the two ends of the dial 520 cover the first water outlet 532 and the second water outlet 533, respectively. At the same time, the straight line formed by the first water outlet 532 and the second water outlet 533 does not pass through the center of the dial 520, i.e. deviates from the center of the water distribution piece 530. In this embodiment, the corresponding central angle of the dial 520 is an acute angle. Of course, on this basis, the central angle of the dial 520 can also be appropriately increased. Based on the straight line formed by the first water outlet 532 and the second water outlet 533, the corresponding central angle of the dial 520 is an acute angle, which reduces the material of the dial 520 and avoids the wear of the dial 520.

[0063] Optionally, as shown in Figure 1 The heating assembly 300 includes a heating disc 310 and a filter screen 320. The heating disc 310 is arranged at the bottom of the inner container 210. The heating disc 310 is provided with a through hole which is in communication with the water distribution valve 500. The filter screen 320 is arranged on the heating disc 310 and is configured to filter impurities in the water flow. Through the above arrangement, the heating disc 310 can heat the water in the inner container 210 to form water vapor. The filter screen 320 can prevent impurities from entering the circulation pipeline during the water circulation process, thereby avoiding damage to the circulation pump 810.

[0064] Optionally, the water inlet 531 and the heating disc 310 are in communication through a second water outlet pipe 780. The length of the second water outlet pipe 780 is very short, and the water storage capacity thereof can be basically ignored.

[0065] As shown in Figure 5 The spray structure 100 includes a connecting pipe 10 and a spray arm 20. One end of the connecting pipe 10 is connected to the top of the inner container 210 (for details, please refer to Figure 9 The spray arm 20 includes at least two straight sections 21 and a bending section 22. The at least two straight sections 21 are distributed radially. The connection positions of the at least two straight sections 21 are rotationally connected to and in communication with the other end of the connecting pipe 10. The free end of each straight section 21 is in communication with one bending section 22. The bending section 22 is clockwise or counterclockwise bent by a preset angle relative to the end of the straight section 21 away from the connection position. The bending directions of the at least two bending sections 22 are consistent.

[0066] The above spray structure 100 is provided with at least two straight sections 21, and each straight section 21 is correspondingly provided with a bending section 22. Water enters the at least two straight sections 21 from the connecting pipe 10 and is sprayed out from the at least two bending sections 22. The water sprayed by the at least two bending sections 22 can be sprayed onto the side wall, thereby cleaning the side wall of the inner container 210. The bending directions of the at least two bending sections 22 are consistent. When water is sprayed out from the two bending sections 22, the high-pressure water acts on the side wall of the inner container 210. Due to the action of the reaction force, the bending section 22 is forced to rotate in the opposite direction.Figure 5 In other words, when viewed from top to bottom, the bending part 22 rotates counterclockwise under the force, and at least two bending parts 22 are subjected to a reaction force, which ensures the balance of the force on both ends of the straight part 21, so that the entire spray arm 20 can continuously rotate under the action of the reaction force, and the front and rear side walls of the inner container 210 are cleaned. Therefore, the spray structure 100 can realize targeted cleaning of the front and rear side walls of the inner container 210, and the rotation of the spray arm 20 does not need to rely on the motor, thereby saving electric energy.

[0067] In the embodiment, as shown in the figure, Figure 5 The straight part 21 is provided with two, and the included angle of the two straight parts 21 is 180°.

[0068] Of course, in other embodiments, the number of straight parts 21 can also be three, four or more, and the two ends of each straight part 21 are provided with a bending part 22, so that multiple bending parts 22 rotate at the same time, the water spraying range is larger, and the cleaning effect is better. Not limited here.

[0069] Optionally, the included angle between the bending part 22 and the corresponding straight part 21 is obtuse, so that the water flow is smoother. In the embodiment, the included angle between the bending part 22 and the straight part 21 is 120°, and in other embodiments, the included angle can be adjusted appropriately, such as 130°, 110°, 100°, etc. Not limited here.

[0070] Optionally, the connection position of the at least two straight parts 21 is the second connection part 23 indicated in Figure 5 , and the at least two straight parts 21 are arranged along the circumference of the second connection part 23. It can be understood that the connecting pipe 10 is connected with the second connection part 23.

[0071] Further, referring to Figure 5 and Figure 9 , the spray structure 100 further comprises two spray arm clamps 40, the second connection part 23 has a ring-shaped side wall, a protrusion capable of being clamped with the two spray arm clamps 40 is formed in the inner side of the ring-shaped side wall, and the connecting pipe 10 is provided with two limiting flanges 11 spaced apart along the axial direction at one end connected with the second connection part 23. When the connecting pipe 10 is connected with the second connection part 23, the two spray arm clamps 40 are first arranged between the two limiting flanges 11, and then inserted into the ring-shaped side wall. Rotate the spray arm clamp 40 to make the two spray arm clamps 40 clamped and fixed with the corresponding protrusions respectively. In this way, the connecting pipe 10 is fixed, and the spray arm clamp 40 and the spray arm 20 rotate at the same time. Among them, the spray arm clamp 40 is a structure in the prior art. In other embodiments, other ways can also be used to make the spray arm 20 rotate relative to the connecting pipe 10. Not limited here.

[0072] Optionally, as shown in Figure 6 andFigure 7 As shown, the spray structure 100 further comprises a scattering water head 30, which is arranged in one-to-one correspondence with the bending part 22 and is connected to the free end of the bending part 22 to scatter the water flow in multiple directions. Through the above arrangement, the water sprayed from the bending part 22 is scattered in multiple directions with the center of the bending part 22 as the axis, so that the position of the water sprayed on the inner container 210 changes from one point to multiple points, the cleaning area is larger, and the cleaning effect is better.
