[0073] like Figure 1 As shown, this embodiment provides an inner liner self-cleaning system, which can realize automatic cleaning of the inner liner 210, saving time and labor, and preventing bacteria from growing in the inner liner 210. The inner tank self-cleaning system includes an inner tank 210, a clean water tank 400, a water diverter valve 500 and a circulating water tank 600. The inner tank 210 can be closed. The inner tank 210 is provided with a heating component 300. The heating component 300 is configured to heat the water in the inner tank 210. A spray structure 100 is also provided in the inner tank 210. The clean water tank 400 can supply water to the spray structure 100 or to the inner tank 210. The water diverter valve 500 is connected to the bottom of the inner tank 210. The water diverter valve 500 has two water outlets. The water diverter valve 500 can close the two water outlets at the same time or open any one of the water outlets separately, and one of the water outlets leads to the oil box 900. The water flowing out from the other water outlet can be stored in the circulating water tank 600 or flow back to the spray structure 100. The circulating water tank 600 can also supply water to the spray structure 100.

[0074] In the above-mentioned liner cleaning system, the user can choose between two cleaning modes. When the liner 210 is less dirty, a simple cleaning mode is executed. Steam cleaning is performed first, the circulating water tank 600 is emptied, and the clean water tank 400 is filled with water. The water diverter valve 500 closes the two water outlets, and the clean water tank 400 supplies water to the liner 210. The heating component 300 works to heat the water in the liner 210 into water vapor; the water outlet leading to the oil box 900 is defined as the first water outlet 532, and the other water outlet is defined as the second water outlet 533. The water diverter valve 500 opens the second water outlet 533 alone, and the clean water tank 400 supplies water to the spray structure 100, and the water flows back to the spray structure 100 through the second water outlet 533 to execute a cleaning procedure; the waste water is discharged into the circulating water tank 600 through the second water outlet 533, and the waste water in the circulating water tank 600 is treated. When the inner tank 210 is seriously dirty, the deep cleaning mode is executed. The circulating water tank 600 and the clean water tank 400 are filled with water, detergent is put into the circulating water tank 600, and the oil box 900 is emptied; the water diversion valve 500 closes the two water outlets, the clean water tank 400 supplies water to the inner tank 210, and the heating component 300 works to heat the water in the inner tank 210 into water vapor; the circulating water tank 600 supplies water to the spray structure 100, and the second outlet is used to clean the inner tank 210. The water outlet 533 flows back to the spray structure 100 again, and a deep cleaning procedure is performed; the waste water of the deep cleaning procedure is discharged from the second water outlet 533 into the circulating water tank 600; the clean water tank 400 supplies water to the spray structure 100, and the water flows back to the spray structure 100 through the second water outlet 533 again, and a rinsing procedure is performed; the first water outlet 532 is opened, and the waste water after the rinsing procedure flows into the oil box 900, and the waste water in the oil box 900 is dumped. Thus, the above-mentioned inner tank cleaning system realizes automatic cleaning of the inner tank 210 through the above settings and the switching of the three states of the water diversion valve 500, and the cleaning mode can be selected according to the situation, saving time and labor, and avoiding the growth of bacteria in the inner tank 210.

[0075] Alternatively, if Figure 1 As shown, the clean water tank 400 is connected to the spray structure 100 through the first pipeline 710, a circulation pump 810 is arranged on the first pipeline 710, the clean water tank 400 is connected to the inside of the inner tank 210 through the second pipeline 720, a water inlet pump 820 is arranged on the second pipeline 720, and the first pipeline 710 is provided with a first solenoid valve 840 upstream of the circulation pump 810. It can be understood that by arranging the circulation pump 810, water is allowed to enter the spray structure 100 and water is pumped out of the inner tank 210 to achieve a clean cycle.

[0076] Alternatively, if Figure 1As shown, the second water outlet 533 is connected to the first pipeline 710 through the third pipeline 730, between the first solenoid valve 840 and the circulation pump 810. It can be understood that the circulation pump 810 completes the circulation path of water from the first pipeline 710 to the inner tank 210, then to the third pipeline 730 and then back to the first pipeline 710, forming a circulation cleaning during cleaning.

[0077] Optionally, the first pipeline 710 and the second pipeline 720 share a first water outlet pipe 770, and a first check valve 860 is provided on the first water outlet pipe 770. The first check valve 860 is configured to allow water to flow out of the clean water tank 400 and prevent water from flowing into the clean water tank 400. By providing the first check valve 860, water is prevented from flowing back into the clean water tank 400, thereby ensuring that the water in the clean water tank 400 is not contaminated.

[0078] Alternatively, if Figure 1 As shown, the third pipeline 730 branches to form a fourth pipeline 740, and the fourth pipeline 740 branches to form a fifth pipeline 750 and a sixth pipeline 760, and the fifth pipeline 750 and the sixth pipeline 760 are respectively connected to the circulating water tank 600, and a second solenoid valve 850 is provided on the fifth pipeline 750, and a drainage pump 830 is provided on the sixth pipeline 760, and the drainage pump 830 is configured to pump water into the circulating water tank 600. Through the above configuration, when a cleaning process is completed, the dirty water is discharged into the circulating water tank 600 by turning on the drainage pump 830.

[0079] Optionally, a second check valve 870 is provided on the sixth pipeline 760, and the second check valve 870 is configured to allow water to flow to the circulating water tank 600 and prevent the water in the circulating water tank 600 from flowing 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 pipeline 740 and then entering the circulating pipeline.

[0080] Alternatively, if Figure 2As shown, the water diverter valve 500 includes a driving member 510, a paddle 520 and a water diverter 530. The water diverter 530 is connected to the main body of the driving member 510 and forms a water inlet 531 and two water outlets. The water inlet 531 is connected to the inner tank 210. The two water outlets are located on the peripheral side of the water diverter 530. The paddle 520 is connected to the output end of the driving member 510 and is close to the inner wall of the water diverter 530. The driving member 510 can drive the paddle 520 to rotate to close the two water outlets at the same time or open one of the water outlets separately. It can be understood that the output end of the driving member 510 can stay in three positions. In the first position, the paddle 520 closes both the first water outlet 532 and the second water outlet 533. In the second position, the first water outlet 532 is open, and the paddle 520 only closes the second water outlet 533. In the third position, the second water outlet 533 is open, and the paddle 520 only closes the first water outlet 532, so as to realize the switching of the three states of the water diverter valve 500.

[0081] Alternatively, if Figure 2 As shown, the paddle 520 includes a sealing portion 521 and a first limiting portion 522, the sealing portion 521 is partially annular and matches the shape of the inner wall of the water diversion member 530, and the first limiting portion 522 is connected to the side of the sealing portion 521 away from the inner wall of the water diversion member 530; the water diversion valve 500 also includes an elastic member 540, the output end of the driving member 510 is circumferentially protruded with a second limiting portion 511, one end of the elastic member 540 abuts against the output end of the driving member 510 and is limited to the second limiting portion 511, and the other end abuts against the sealing portion 521 and is limited to the first limiting portion 522. Through the above arrangement, the elastic member 540 can tightly abut the paddle 520 against the inner wall of the water diversion member 530 to ensure the tightness of the seal, and at the same time, the elastic member 540 is limited by the first limiting portion 522 and the second limiting portion 511 to prevent the elastic member 540 from moving during use. In this embodiment, the first limiting portion 522 is annular and the second limiting portion 511 is cylindrical. In other embodiments, the two can be interchangeable or both can be annular or both can be cylindrical, as long as they match the end shape of the elastic member 540, and are not limited here.

[0082] In an optional embodiment, one of the limiting cases, such as Figure 3 As shown, when the paddle 520 covers the first water outlet 532 and the second water outlet 533 at the same time, that is, in the closed state, the two ends of the paddle 520 just 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 circle, that is, it deviates from the center of the water diversion member 530. In this embodiment, the central angle of the paddle 520 is an obtuse angle. Of course, on this basis, the central angle of the paddle 520 can be appropriately increased.

[0083] In another optional embodiment, another limiting case, such as Figure 4 As shown, the paddle 520 covers the first water outlet 532 and the second water outlet 533 at the same time, that is, when it is in the closed state, the two ends of the paddle 520 just 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 circle, that is, it deviates from the center of the water diversion member 530. In this embodiment, the center angle of the paddle 520 is an acute angle. Of course, on this basis, the center angle of the paddle 520 can be appropriately increased. Based on the straight line formed by the first water outlet 532 and the second water outlet 533, the center angle of the paddle 520 is an acute angle, which reduces the material used for the paddle 520 and avoids wear of the paddle 520.

[0084] Alternatively, if Figure 1 As shown, the heating assembly 300 includes a heating plate 310 and a filter 320. The heating plate 310 is arranged at the bottom of the inner tank 210. A through hole is opened on the heating plate 310, and the through hole is connected to the water diversion valve 500. The filter 320 is covered on the heating plate 310 and is configured to filter impurities in the water flow. Through the above arrangement, the heating plate 310 heats the water inside the inner tank 210 to form water vapor, and the filter 320 prevents impurities from entering the circulation pipeline during the water circulation process, thereby avoiding damage to the circulation pump 810.

[0085] Optionally, the water inlet 531 and the heating plate 310 are connected via a second water outlet pipe 780 . The length of the second water outlet pipe 780 is very short, and the amount of water stored therein can be basically ignored.

[0086] like Figure 5 As shown, the spray structure 100 includes a connecting pipe 10 and a spray arm 20, and one end of the connecting pipe 10 is connected to the top of the inner tank 210 (see Fig. 9 ), the spray arm 20 includes at least two straight portions 21 and a bent portion 22, at least two straight portions 21 are evenly distributed radially, the connection position of at least two straight portions 21 is rotationally connected and communicated with the other end of the connecting pipe 10, the free end of each straight portion 21 is connected with a bent portion 22, the bent portion 22 is bent clockwise or counterclockwise at a preset angle relative to the end of the straight portion 21 away from the connection position, and the bending directions of at least two bent portions 22 are consistent.

[0087] The above-mentioned spray structure 100 is provided with at least two straight parts 21, and each straight part 21 is correspondingly provided with a bent part 22. Water enters from the connecting pipe 10 into the at least two straight parts 21 and then sprays out from the at least two bent parts 22. The water sprayed from the at least two bent parts 22 can be sprayed onto the side wall, thereby cleaning the side wall of the inner tank 210. The bending directions of the at least two bent parts 22 are consistent. When water is sprayed from the two bent parts 22, the high-pressure water acts on the side wall of the inner tank 210. Due to the reaction force, the bent part 22 is forced to rotate in the opposite direction, targeting Figure 5 From the top down, when the bending part 22 is subjected to force, the bending part 22 rotates counterclockwise, and at least two bending parts 22 are subjected to the reaction force at the same time, ensuring the force balance at both ends of the straight part 21, so that the entire spray arm 20 can continue to rotate under the action of the reaction force, and the front, back, left and right side walls of the inner tank 210 are completely cleaned. Therefore, the spray structure 100 can achieve targeted cleaning of the front, back, left and right side walls of the inner tank 210, and the rotation of the spray arm 20 does not need to rely on a motor, saving electric energy.

[0088] In this embodiment, Figure 5 As shown, there are two straight portions 21 , and the included angle between the two straight portions 21 is 180°.

[0089] Of course, in other embodiments, the number of straight portions 21 can also be set to three, four or more, and bending portions 22 are provided at both ends of each straight portion 21. Thus, multiple bending portions 22 rotate simultaneously, the water spraying range is larger, and the cleaning effect is better, which is not limited here.

[0090] Optionally, the angle between the bend 22 and the corresponding straight portion 21 is an obtuse angle, so that the water flow is smoother. In this embodiment, the angle between the bend 22 and the straight portion 21 is 120°. In other embodiments, the angle can be appropriately adjusted, such as 130°, 110°, 100°, etc., which is not limited here.

[0091] Optionally, the connection position of at least two straight portions 21 is Figure 5 In the second connection portion 23 indicated in FIG. 1 , at least two straight portions 21 are arranged at intervals along the circumference of the second connection portion 23 . It can be understood that the connecting pipe 10 is connected to the second connection portion 23 .

[0092] Furthermore, see also Figure 5 and Fig. 9 The spray structure 100 also includes two spray arm clamps 40. The second connection part 23 has an annular side wall. The inner side of the annular side wall is provided with protrusions that can be clamped with the two spray arm clamps 40. The connecting pipe 10 is provided with two limit flanges 11 spaced along its axial direction at one end connected to the second connection part 23. When the connecting pipe 10 is connected to the second connection part 23, the two spray arm clamps 40 are firstly surrounded between the two limit flanges 11, and then inserted into the annular side wall. The spray arm clamps 40 are rotated so that the two spray arm clamps 40 are respectively clamped and fixed with the corresponding protrusions. In this way, the connecting pipe 10 is fixed, and the spray arm clamps 40 and the spray arm 20 rotate at the same time. Among them, the spray arm clamps 40 are structures in the prior art. In other embodiments, other methods can be used to make the spray arm 20 rotate relative to the connecting pipe 10, which is not limited here.

[0093] Alternatively, if Figure 6 and Figure 7 As shown, the spray structure 100 further includes a scattering water head 30, which is arranged one-to-one with the bent portion 22, and is connected to the free end of the bent portion 22 to scatter the water flow in multiple directions. Through the above arrangement, the water sprayed from the bent portion 22 is dispersed in multiple directions with the center of the bent portion 22 as the axis, so that the position where the water is sprayed onto the inner tank 210 changes from one point to multiple points, so that the cleaning area is larger and the cleaning effect is better.

[0094] In an optional embodiment, if Figure 6 and Figure 7 As shown, the bending portion 22 includes a main body 221, a water outlet portion 222 and a blocking portion 223. The main body 221 is connected to one end of the straight portion 21; the water outlet portion 222 is connected to one end of the main body 221 away from the straight portion 21 and is provided with a plurality of first water outlet holes 2221; the blocking portion 223 is connected to one end of the water outlet portion 222 away from the main body 221; a water containing space 31 is formed inside the scattering water outlet head 30 and is connected to the main body 221, and a plurality of first water outlet holes 2221 are located in the water containing space 31. The scattering water outlet head 30 is also provided with scattering holes 32 connected to the water containing space 31, and at least part of the blocking portion 223 is located in the scattering holes 32. Through the above arrangement, the water hole main body 221 enters the water outlet portion 222 and enters the water holding space 31 from the plurality of first water outlet holes 2221, and is evenly filled in the water holding space 31. Due to the action of the blocking portion 223, when water overflows from the water holding space 31, it passes through the scattering hole 32, and a portion of the space of the scattering hole 32 is occupied by the blocking portion 223, forcing the water to spray out along the side wall of the scattering hole 32, thereby causing the water to spray out in multiple directions along the side wall of the scattering hole 32, and a larger spraying area.

[0095] Alternatively, if Figure 7 As shown, the hole wall of the scattering hole 32 is set in a cone shape, so that the water flow is sprayed in an umbrella shape.

[0096] Alternatively, if Figure 7 As shown, the blocking portion 223 is fixedly connected to the water outlet portion 222, the diameter of the blocking portion 223 is D1, the water storage space 31 and the scattering hole 32 are connected through the avoidance hole 33, the diameter of the avoidance hole 33 is D2, and D2>D1. Through the above arrangement, when the scattering water outlet head 30 is installed, the blocking portion 223 can pass through the avoidance hole 33 to avoid interference. At the same time, the arrangement of the avoidance hole 33 avoids the scattering hole 32 from being directly connected to the water storage space 31, which causes the wall thickness of the scattering hole 32 to be too thin and the strength to be insufficient.

[0097] Optionally, the blocking portion 223 and the water outlet portion 222 are connected by a first connecting portion 224, the diameter of the first connecting portion 224 is smaller than the diameter of the avoidance hole 33 and the first connecting portion 224 is arranged to penetrate the avoidance hole 33, thereby ensuring that water can flow quickly through the smaller gap between the two, increasing the flow rate of water and improving the cleaning ability.

[0098] In an alternative embodiment, see Figure 6 and Figure 7 The blocking portion 223 is a columnar body. In another optional embodiment, the blocking portion 223 may also be a sphere or a cone, etc., which is not limited here.

[0099] Optionally, a plurality of first water outlet holes 2221 are evenly arranged around the water outlet portion 222, and the uniform flow speed is faster. In another embodiment, the first water outlet hole 2221 can also be arranged on the side where the water outlet portion 222 is connected to the first connecting portion 224, which is not limited here.

[0100] In this embodiment, the scattering water head 30 is connected to the main body 221 by threads. In other embodiments, they can also be connected by snap-fit, which is not limited here.

[0101] In another optional embodiment, the blocking portion 223 can also be detachably connected to the water outlet portion 222. After the scattering water outlet head 30 is installed, the blocking portion 223 and the water outlet portion 222 are connected, for example, by threading. Thus, the avoidance hole 33 can be opened to be smaller than the diameter of the blocking portion 223, allowing only the first connecting portion 224 to pass through.

[0102] In order to further improve the cleaning effect on the top of the inner tank 210, as Figure 8 As shown, a plurality of second water outlet holes 2121 are provided on the upper side of the straight portion 21, and at least two of the plurality of second water outlet holes 2121 have different water outlet directions. Through the above arrangement, the plurality of water outlet holes on the straight portion 21 are used to clean the heating pipe on the top of the inner tank 210 and the bottom (the cleaning of the bottom is mainly done by water flowing down from the inner wall), and the different directions can cover a wider cleaning area.

[0103] In an optional embodiment, if Figure 8As shown, the straight portion 21 includes a main body 211 and a plurality of plugs 212, the main body 211 is provided with a mounting hole (not numbered) for mounting the plug 212, the plug 212 is interference-fitted with the mounting hole, and the second water outlet 2121 is provided on the plug 212, wherein the top of the plug 212 is an inclined surface, when drilling, the second water outlet 2121 is based on the inclined surface, and the second water outlet 2121 is substantially perpendicular to the inclined surface, thereby, by rotating the plug 212, different second water outlets 2121 can be easily directed in different directions. Optionally, the plug 212 is made of a soft material, such as rubber, which can achieve a good seal with the mounting hole.

[0104] Of course, in another embodiment, the plug 212 and the straight portion 21 may also be manufactured in one piece, which is not limited here.

[0105] Optionally, a second water outlet 2121 may be provided on the lower side of the straight portion 21 to perform targeted cleaning on the bottom wall of the inner tank 210, which will not be described in detail here.

[0106] Optionally, the spray arm 20 is a plastic part (excluding the plug 212), and is formed by hot-melt splicing of the upper and lower parts. It is understandable that when the spray arm 20 is a plastic part, the bent shape is not easy to be formed in one step, for example, demoulding is difficult, that is, it is difficult to form the spray arm 20 in a horizontal plane. Figure 8 The spray arm 20 is cut into two parts, the upper and lower parts are manufactured separately, and then hot-melt splicing is performed to realize the molding of the spray arm 20.

[0107] Of course, in other embodiments, if the spray arm 20 is made of metal or other materials, it can be integrally formed, which is not limited here.

[0108] Optionally, the liner assembly 200 includes an liner 210 and the above-mentioned spray structure 100, and the spray structure 100 is connected to the top of the liner 210. The liner assembly 200 adopts the above-mentioned spray structure 100, so that multiple inner walls of the liner 210 can be well targeted and cleaned, and the spray arm 20 can rotate without using a motor, saving power.

[0109] Optionally, continue to see Fig. 9 A through hole is provided on the inner liner 210, and the connecting protrusion 230 is installed on the inner liner 210 and arranged corresponding to the through hole. The connecting piece 220 is connected to the connecting protrusion 230 by a thread. Specifically, the outer wall of the connecting piece 220 is threadedly connected to the inner wall of the connecting protrusion 230, and a seal is provided between the connecting piece 220 and the inner liner 210 to prevent water vapor from escaping to the outside; further, the outer wall of the top of the connecting tube 10 is threadedly connected to the inner wall of the connecting piece 220. When the inner liner 210 needs to be cleaned, the two are connected. After cleaning, the connecting tube 10 can be quickly removed.

[0110] It should be noted that the inner pot assembly 200 can be applied to various cooking utensils. The cooking utensils can perform all-round targeted cleaning of the inner pot 210 by using the inner pot assembly 200, and the spray arm 20 can rotate automatically without using a motor, thus saving power.

[0111] It should be noted that the cooking utensil may be a cooking utensil with an inner pot 210, such as a steamer, an oven, or a steamer-bake-in-one oven, and is not limited here.

[0112] This embodiment also provides an integrated stove, including the above-mentioned inner pot self-cleaning system. By adopting the above-mentioned inner pot self-cleaning system, the integrated stove can realize automatic cleaning of the inner pot 210, saving time and labor, and improving the use experience of consumers.

[0113] This embodiment also provides a cleaning method of the inner tank self-cleaning system, which is used to clean the inner tank 210. The cleaning method of the inner tank self-cleaning system is divided into a simple cleaning mode and a deep cleaning mode. The simple cleaning mode includes:

[0114] S1: Steam cleaning, the circulating water tank 600 is emptied, the clean water tank 400 is filled with water, the water diversion valve 500 closes the two water outlets, the clean water tank 400 supplies water to the inner tank 210, and the heating component 300 works to heat the water in the inner tank 210 into water vapor;

[0115] S2: define the water outlet leading to the oil box 900 as the first water outlet 532, define another water outlet as the second water outlet 533, the water diversion valve 500 opens the second water outlet 533 alone, the clean water tank 400 supplies water to the spray structure 100, and the water flows back to the spray structure 100 through the second water outlet 533, and a cleaning procedure is performed;

[0116] S3: discharging the wastewater into the circulating water tank 600 through the second water outlet 533, and treating the wastewater in the circulating water tank 600;

[0117] Deep Cleaning Mode includes:

[0118] S10: Fill the circulating water tank 600 and the clean water tank 400 with water, put detergent into the circulating water tank 600, and empty the oil box 900;

[0119] S20: The water diversion valve 500 closes the two water outlets, the clean water tank 400 supplies water to the inner tank 210, and the heating component 300 works to heat the water in the inner tank 210 into water vapor;

[0120] S30: define the water outlet leading to the oil box 900 as the first water outlet 532, define another water outlet as the second water outlet 533, the water diversion valve 500 opens the second water outlet 533 alone, the circulating water tank 600 supplies water to the spray structure 100, and the water flows back to the spray structure 100 through the second water outlet 533, and a deep cleaning procedure is performed;

[0121] S40: Discharge the waste water of the deep cleaning process from the second water outlet 533 into the circulating water tank 600;

[0122] S50: the clean water tank 400 supplies water to the spray structure 100, and the water flows back to the spray structure 100 through the second water outlet 533 to perform a rinsing process;

[0123] S60: Open the first water outlet 532, and the waste water after the rinsing process flows into the oil box 900, and the waste water in the oil box 900 is dumped.

[0124] The cleaning method of the inner tank self-cleaning system provides the user with two inner tank 210 self-cleaning modes to choose from by combining the switching of the three states of the water diversion valve 500 and the setting of the water path, thereby saving time and effort and avoiding the growth of bacteria in the inner tank 210.

[0125] Optionally, in S10, the water in the clean water tank 400 is driven into the inner pot 210 by turning on the water inlet pump 820, and the water inlet pump 820 is turned off before S2; thereby, a small amount of water is pumped into the inner pot 210 along the second pipeline 720 to achieve steam washing. Furthermore, this steam washing can also be the steam provided for cooking food in the inner pot 210.

[0126] Optionally, in S2, the circulation pump 810 is turned on to drive the water in the clean water tank 400 to supply water to the spray structure 100 and drive the water flow from the second water outlet 533 to flow back to the spray structure 100 again to achieve circulation cleaning, and the water diversion valve 500 is temporarily closed before turning on the circulation pump 810; through the above-mentioned setting, the water in the clean water tank 400 is first pumped into the inner tank 210 through the spray structure 100, and the water soaks the bottom of the inner tank 210 before circulating.

[0128] Optionally, in S30, the circulating pump 810 is turned on to drive the water in the circulating water tank 600 to flow toward the spray structure 100, and then flows back to the spray structure 100 through the second water outlet 533, so as to realize the circulation and cleaning of water in the circulating water circuit (the first pipeline 710 and the third pipeline 730).

[0129] In S40, the waste water of the deep cleaning process is discharged into the circulating water tank 600 by turning on the drain pump 830. This is similar to the principle of draining waste water of simple cleaning.

[0130] Optionally, when the cleaning procedure is executed for the first time, each cleaning procedure uses part of the water in the clean water tank 400, and S2 is executed at least twice. That is, the water in the clean water tank 400 is cleaned in a step-by-step cycle twice or more to avoid insufficient cleaning in one time and causing dirt residue.

[0131] Adaptively, a liquid level sensor is provided in the clean water tank 400, and the liquid level sensor is communicatively connected with the first electromagnetic valve 840 and the water diverter valve 500. In this embodiment, when the cleaning procedure is performed for the first time, one-half of the water in the clean water tank is used, that is, when the liquid level sensor detects that the water level reaches one-half, the first electromagnetic valve 840 is closed, the water diverter valve 500 opens the second water outlet 533, and the circulation pump 810 starts circulating cleaning. In other embodiments, the cleaning procedure can also be performed three times or more, which is not limited here.

[0132] Optionally, S50 and S60 are performed at least twice in sequence, and each rinsing process uses at least part of the water in the clean water tank 400. In other words, the rinsing step in the deep cleaning mode is actually similar to the cleaning process in the simple cleaning mode. S50 and S60 are performed at least twice to ensure that the rinsing is in place and there is no detergent residue in the inner tank 210.
