DETAILED DESCRIPTION OF THE INVENTION

[055] The embodiments of the present disclosure will be described in detail, and examples of the embodiments are shown in the drawings. The same or similar elements and elements that have the same or similar functions are indicated by similar reference numerals throughout the descriptions. The embodiments described herein with reference to the drawings are explanatory and used to generally understand the present disclosure. The findings should not be construed as limiting the present disclosure.

[056] A water supply system for a dishwasher 100, in accordance with embodiments of a first aspect of the present disclosure, will be described with reference to Figs. 1 to 28.

[057] As illustrated in Figs. 1 to 9, the water supply system for the dishwasher 100, in accordance with embodiments of the first aspect of the present disclosure, includes: an internal container assembly 1, a water tank 2, a descaler 3 and a generator of steam 5.

[058] Specifically, the water tank 2 has a water flow chamber 202, and the water flow chamber 202 of the water tank 2 is connected to the inner container assembly 1 and configured to supply water to the inner container assembly 1, in order to wash dishes in the inner container assembly 1. The water drain chamber 202 can store the water that fills a complete wash cycle of the dishwasher 100, so that not only the water that enters the chamber The water flow chamber 202 can be controlled by a water inlet valve, but water can also be supplied to the water flow chamber 202 manually. Thus, it is possible to supply water to the internal container assembly 1 of the dishwasher 100 in various ways to improve applicability, so that the dishwasher can be applied in areas without running water, or an external water source can be used. to supply water to the dishwasher 100 when the water supply is suddenly cut off. Furthermore, because dishwashing water can be stored in water tank 2 in advance, a dishwashing process is not affected by an external water injection speed, thus improving the dishwashing efficiency of the dishwasher 100.

[059] The steam generator 5 is connected in series between the water flow chamber 202 of the water tank and the inner container assembly 1, and is configured to supply high temperature water or steam to the inner container assembly 1. For example, during the water washing process of the dishwasher 100, the water in the water drain chamber 202 of the water tank 2 enters the steam generator 5 and then enters the inner container assembly 1, in which case the steam generator 5 only serves as a passage for water circulation; When the water washing process is completed, the steam generator 5 is used to disinfect the inner container assembly 1 and the dishes in the inner container assembly 1, so that the water in the water drain chamber 202 enters the generator steam generator 5, the steam generator 5 heats the water to form high-temperature gaseous steam, and the high-temperature steam enters the inner container assembly 1 to sterilize and disinfect the dishwasher 100. Thus, a cleaning effect and The efficiency of the dishwasher 100 can be further improved, and the dishwasher 100 also has the ability to sterilize and disinfect.

[060] The softener 3 has a descaling assembly 31, and the softener 3 is provided with a softener water outlet 303 and a softener water inlet (such as a first softener water inlet 301 and a second water inlet of water softener 302 illustrated below). The softener water outlet 303 and the softener water inlet are both in communication with the descaling assembly 31, and the softener water outlet 303 of the softener 3 is connected to the water drain chamber 202 to supply softened water to the water drain chamber 202. That is, water enters the water softener 3 through the water inlet of the water softener and is descaled by means of the descaling assembly 31 of the water softener 3 to remove calcium and magnesium ions in the water, and the pure water resultant enters the water drain chamber 202 through the water outlet of the descaler 303 and then flows to the inner container assembly 1 from the water drain chamber 202 for washing dishes. Therefore, it is possible to prevent the formation of scale inside the inner container assembly 1 and the water drain chamber 202 of the water tank, so as to enhance the cleaning effect and improve the user experience of the dishwasher 100.

[061] In the water supply system of the dishwasher 100, according to the embodiments of the present disclosure, by providing the water tank 2 to supply water to the inner container assembly 1, the dishwasher 100 can supply water to the assembly of inner container 1 when manually supplying water to water tank 2, improving applicability. Furthermore, the descaler 3 is connected in series in the water supply system, and the water can be descaled to prevent scale arising from accumulation in the internal container assembly 1 and in the water drain chamber 202, so as to enhance an effect of dishwashing.

[062] In one embodiment of the present disclosure, the water supply system may further include a water inlet valve, and the water inlet of the softener is connected to the water inlet valve. The water inlet valve can be opened when necessary for washing dishes or for injecting water into the water drain chamber 202, and therefore the tap water can pass through the water inlet valve and the water inlet of the softener sequentially, and enter the descaling assembly 31 to be descaled. When water washing is completed or the water drain chamber 202 is filled with water (or the water reaches a preset water level), the water inlet valve can be closed. Thus, it is possible to control whether the water supply system is in communication with the external water source through the water inlet valve in convenient and simple operations.

[063] In some embodiments, the water supply system may further include a water supply chamber 201, the water supply chamber 201 may have a manual water supply port 204, and the softener water inlet ( for example, the second water inlet of the water softener 302 illustrated below) is connected to the water supply chamber 201. When it is necessary to supply water manually, the user can supply water to the water supply chamber 201 through the water supply port manual 204, the water in the water supply chamber 201 enters the softener 3 through the softener water inlet to be descaled, and the pure water flowing out of the softener 3 then enters the inner container assembly 1 through the chamber water drain 202 for washing dishes.

[064] In some other embodiments, the water supply system may include both the water inlet valve and the water supply chamber 201, the water supply chamber 201 has the manual water supply port 204, and the water inlet of the softener is connected to the water inlet valve and the water supply chamber 201 separately. One softener water inlet may be provided and connected to both the water inlet valve and the water supply chamber 201, or two softener water inlets may be provided and connected to the water inlet valve and the supply chamber of water 201, respectively. That is, when there is a softener water inlet, the softener water inlet, water inlet valve and water supply chamber 201 are connected in series. When there are two water softener inlets, one of the two water softener inlets (e.g. the first water inlet of the water softener 301) is connected to the water inlet valve in series, e.g. the external tap water enters the descaling assembly 31 through the water inlet valve and the first water inlet of the water softener 301 sequentially, in which case one mode of supplying tap water is adopted, and the other a water inlet of the water softener (e.g. , the second water inlet of the water softener 302) is connected to the water supply chamber 201 in series, for example, the user can supply water to the water supply chamber 201 through the manual water supply port 204 and the water enters in the descaling assembly 31 of the descaler 3 through the second water inlet of the descaler 302, in which case a manual water supply mode is adopted by the dishwasher 100. In other words, the automatic water supply mode from the tap and The manual water supply mode corresponds to a water inlet of the water softener, and therefore a structure of the water supply system can be simplified and the external pipes can be connected conveniently.

[065] In some embodiments, as illustrated in Figs. 12 to 14, a first division plate 21 may be provided in the water tank 2, the first division plate 21 defines the water flow chamber 202 and the water supply chamber 201 in the water tank 2, and the chamber water flow chamber 202 and the water supply chamber 201 are separated along a horizontal direction (in a left-to-right direction in Fig. 13). The manual water supply port 204 is formed in the upper part of the water supply chamber 201, and the water inlet of the softener is connected to a lower part of the water supply chamber 201. In combination with Fig. 14, the manual water supply port 204 is formed on a left side of an upper part of the water tank 2, and the first division plate 21 is disposed on the water tank 2 and located on a right side of the water supply port manual 204. In a top-to-bottom direction, at least part of the first division plate 21 slopes and extends from right to left. The first division plate 21 divides the space in the water tank 2 into the water supply chamber 201 on the left side and the water outflow chamber 202 on the right side, the lower part of the water supply chamber 201 may be in communication with a lower part of the water outlet chamber 202, and when the lower part of the water supply chamber 201 is not in communication with the lower part of the water outlet chamber 202, the lower part of the water supply chamber 201 is connected to the water inlet of the softener.

[066] Preferably, the first division plate 21 extends from the bottom until it is adjacent to the upper part of the water tank 2. That is, the upper part of the water supply chamber 201 is in communication with the upper part of the chamber water flow chamber 202, such that when the water flow chamber 202 injects water into the inner container assembly 1, the air pressure in the water flow chamber 202 is decreased, in which case external air enters the water flow chamber 202. Water flow 202 through the manual water supply port 204 and an upper part of the first partition plate 21 balances the air pressure and achieves a ventilation effect. Of course, when water is injected into the water flow chamber 202, the air pressure in the water flow chamber 202 increases, and a flow of air in the water flow chamber 202 can also be released through the water supply port. manual water 204.

[067] In some embodiments, the descaling assembly 31 of the descaler 3 includes a region chamber filled with resin, and after the resin softens the calcium and magnesium ions in the water the resin needs to be regenerated. Preferably, as illustrated in Figs. 15 to 17, the softener 3 may further have a regeneration assembly 32 configured to regenerate the softener assembly 31. The regeneration assembly 32 may include a salt cavity 321, a water inlet passage 322 and a switching valve 323. the salt cavity 321 being connected to the descaling assembly 31, the water inlet passage 322 being connected to the salt cavity 321, and the switching valve 323 being configured to open or close the water inlet passage 322. When mounting descaling assembly 31 needs to be regenerated, the switching valve 323 can be opened so that water can enter the saline cavity 321 to form a saturated saline solution, and then the saline solution enters the descaling assembly 31 to implement the regeneration of the descaling assembly. descaling 31.

[068] Advantageously, as illustrated in Fig. 14, a second division plate 22 can be arranged in the water tank 2, the second division plate 22 defines a regeneration chamber 203 separate from the water flow chamber 202 in the water tank 2, and the water flow chamber 202 is in communication with an upper part of the regeneration chamber 203. In combination with Fig. 14, the second dividing plate 22 extends vertically from a lower wall of the water tank 2, and the water flow chamber 202 is in communication with an upper part of the regeneration chamber 203. In combination with Fig. water 2 and is separated from an upper wall of the water tank 2, the water drainage chamber 202 is located on a left side of the second division plate 22 while the regeneration chamber 203 is located on a right side of the second division plate. division 22, and a position where the regeneration chamber 203 and the water outlet chamber 202 are in communication is not greater than the highest water level of the water outlet chamber 202. That is, when the water level in the chamber water drainage chamber 202 gradually increases beyond the height of the second dividing plate 22 (at this time, the highest water level of the water drainage chamber 202 has not yet been reached), the water in the water drainage chamber 202 may overflow the second divider plate 22 and enter the regeneration chamber 203, and as a lower part of the regeneration chamber 203 is connected to the water inlet passage 322, water can be injected into the saline cavity 321 through the water inlet passage 322 to form the saturated saline solution for regeneration of the descaling assembly 31.

[069] Preferably, the descaler 3 can define a salt supply port 325 in communication with the salt cavity 321, the salt supply port 325 is opened or closed by a lid, and the salt cavity 321 is further provided with a descaling device. salt shortage detection 324. When the salt shortage detection device 324 detects that the salt in the salt cavity 321 is insufficient (insufficient to form saturated saline solution), the user can open the lid to supply salt into the salt cavity 321 through the saline supply port 325 to ensure efficient regeneration of the descaling assembly 31.

[070] Preferably, an air inlet tube 25 may be arranged in the water tank 2, a first end of the air inlet tube 25 (for example, an upper end of the air inlet tube 25 shown in Fig. 14 ) communicates with, and closes, a water tank air inlet 205, and a second end of the air inlet tube 25 (e.g., a lower end of the air inlet tube 25 shown in Fig. 14) if extends to a lower part of the water tank 2. Thus, when the water in the water tank 2 is injected into the inner container assembly 1 and the air pressure in the water tank 2 decreases, outside air can enter the water tank 2 through the air inlet pipe 25 to balance the air pressure inside and outside the water tank 2, so as to ensure that the water in the water tank 2 can flow towards the inner container assembly 1 smoothly.

[071] Advantageously, a water level detection device 24 is arranged in the water drain chamber 202 of the water tank 2, and the water level detection device 24 can be used to detect a water level in the tank of water 2. Therefore, a degree of automation of the dishwasher 100 can be increased, and the water level in the water tank 2 can be monitored in real time. For example, when the water level detection device 24 detects that the water level in the water drain chamber 202 reaches a predetermined water level, a signal may be communicated to a control component, and the control component may control the interruption of water injection into the water drainage chamber 202.

[072] A dishwasher 100, in accordance with embodiments of a second aspect of the present disclosure, includes an internal container 1, a water tank 2, a spray arm assembly 8, a wash pump 7 and a pump drainage 6.

[073] Specifically, the water tank 2 is connected to the inner container assembly 1 and configured to supply water to the inner container assembly 1. The water tank 2 has a manual water supply port 204, and the user can supply water to the water tank 2 through the manual water supply port 204. Of course, the water tank 2 can also adopt a non-manual water supply mode, and for example, the user can connect the water tank 2 to a tap water pipe directly to supply water to the water tank 2 directly through the tap water pipe.

[074] The spray arm assembly 8 is provided in the inner container assembly 1, the wash pump 7 is connected to the inner container assembly 1 and the spray arm assembly 8 separately and configured to pump water from an inner container 11 for spray arm assembly 8. Drain pump 6 is connected to inner bowl assembly 1 and configured to drain water into inner bowl assembly 1.

[075] A specific work process of the dishwasher 100 will now be described. When it is necessary to wash dishes with the dishwasher 100, the user can choose to supply water to the water tank 2 manually or directly through the tap water pipe. At the end or during water supply, the water in the water tank 2 flows towards the inner container assembly 1. In this action of the wash pump 7, the wash pump 7 pumps water from the inner container assembly 1 to the spray arm assembly 8. The spray arm assembly 8 sprays water onto the dishes to be cleaned for washing dishes. After spraying is finished, the water in the inner container assembly 1 is drained by the drain pump 6.

[076] For the dishwasher 100, according to the embodiments of the present disclosure, by providing the water tank 2 additionally and by providing the water tank 2 with the manual water supply port 204, it is possible to supply water to the dishwasher 100 manually to wash the dishes, thus improving the applicability of the dishwasher 100 and enhancing its overall performance.

[077] Furthermore, the dishwasher 100 further includes the water supply system in accordance with the embodiments of the first aspect of the present disclosure. Thus, it is possible to descale the water entering the inner container assembly 1, prevent scale formation within the inner container assembly 1, improve the cleaning effect on the dishes and improve the overall performance of the dishwasher 100.

[078] Preferably, a base water inlet 101 may be provided in a lower part of the inner container assembly 1 and is in communication with an internal space of the inner container assembly 1. The water tank 2 may be connected to the water inlet 101. base water 101 of the inner container assembly 1, that is, the water tank 2 is in communication with the inner space of the inner container assembly 1 through the base water inlet 101. In other words, the water in the water tank 2 can enter the inner container assembly 1 through the base water inlet 101 for washing dishes in the inner container assembly 1.

[079] Advantageously, the water tank 2 can be arranged outside the inner container assembly 1 to avoid occupying the internal space of the inner container assembly 1 and ensure efficient dishwashing of the inner container assembly 1. The tank water tank 2 can be mounted on a side wall of the inner container assembly 1 to shorten the distance between the water tank 2 and the inner container assembly 1 to facilitate direct supply of water from the water tank 2 to the container assembly 1. Preferably, a lower part of the water tank 2 may be larger than the base water inlet 101 of the internal container assembly 1. Thus, when there is no need to provide power (e.g., pumping), the water in the tank of water 2 can also automatically flow into the base water inlet 101 and enter the inner container assembly 1 under gravity, so that the structure of the dishwasher 100 becomes simpler, more compact and reasonable.

[080] In some embodiments, the manual water supply port 204 is sealed by a filter screen. The filter screen can filter impurities in the water to prevent impurities from entering the water tank 2 and the inner container assembly 1 downstream of the water tank 2, so as to ensure the cleaning effect on the dishes.

[081] Preferably, as illustrated in Fig. 14, the lower part of the water tank 2 can be provided with a drain valve 23, the drain valve 23 can be connected to the lower part of the water tank 2 and the lower part of the inner container assembly 1 separately, and the drain valve 23 is a manually operated valve or an electrically operated valve. By controlling the opening and closing of the drain valve 23, it is possible to control whether the water tank 2 and the inner container assembly 1 are in communication, so as to conveniently control whether water is supplied to the inner container assembly 1 .

[082] In some embodiments, the inner container assembly 1 may be provided with an inner container air inlet 102 and an inner container air outlet. When the pressure in the inner container assembly 1 is too high, air in the inner container assembly 1 can circulate through the air outlet of the inner container. When the pressure in the inner container assembly 1 is too low, outside air can enter the inner container 11 through the inner container air inlet 102 to balance the air pressure inside and outside the inner container assembly 1. Furthermore, The water tank 2 may be provided with a water tank air inlet 205, and the water tank air inlet 205 is in communication with the air outlet of the inner container, so that when the air pressure in the inner container assembly 1 is too high, the air in the inner container assembly 1 may enter the water tank 2 through the inner container air outlet and the water tank air inlet 205 sequentially, and as a result, the pressure difference in the water tank 2 and the inner container assembly 1 can be balanced, and the air pressure in the water tank 2 can be balanced with the external atmospheric pressure through the manual water supply port 204.

[083] Preferably, an air inlet tube 25 may be arranged in the water tank 2, a first end of the air inlet tube 25 (for example, an upper end of the air inlet tube 25 shown in Fig. 14 ) is in communication with, and closes, a water tank air inlet 205, and a second end of the air inlet tube 25 (e.g., a lower end of the air inlet tube 25 shown in Fig. 14) extends to a lower part of the water tank 2. Thus, when the water in the water tank 2 is injected into the inner container assembly 1 and the air pressure in the water tank 2 decreases, outside air can enter the water tank 2. water 2 through the air inlet pipe 25 to balance the air pressure inside and outside the water tank 2, so as to ensure that the water in the water tank 2 can flow towards the inner container assembly 1 smoothly.

[084] Advantageously, a water level detection device 24 is disposed in a water drain chamber 202 of the water tank 2, and the water level detection device 24 can be used to detect a level of water in the water tank 2. Therefore, the degree of automation of the dishwasher 100 can be increased and the water level in the water tank 2 can be monitored in real time. For example, when the water level detection device 24 detects that the water level in the water tank 2 reaches a predetermined water level, a signal may be sent back to a control component, and the control component may control the interruption of water injection into the water drainage chamber 202.

[085] In some embodiments of the present disclosure, the dishwasher 100 may further include an anti-siphon fan assembly 4. The anti-siphon fan assembly 4 may include a portion of the frame 41, and the portion of the frame 41 defines a flow passage of water 412 and a balancing passage 411 therein. The water flow passage 412 has a first end (e.g., a left end of the water flow passage 412 illustrated in Fig. 11) connected to an outlet of the drain pump 6, and a second end (e.g., a right end of the water flow passage 412 illustrated in Fig. 11) configured to drain water. When the dishwasher 100 drains water, the drain pump 6 works and the water in the inner container assembly 1 enters the water flow passage 412 through the drain pump 6 and is then drained through the water flow passage 412 (e.g. drained into a sewer). Furthermore, the balancing passage 411 may be connected to the water flow passage 412 and has a vent hole 4114, the vent hole 4114 being configured to balance the air pressure in and out of the water flow passage 412.

[086] Advantageously, as illustrated in Fig. 11, a one-way valve 4118 is disposed in the balancing passage 411, and the one-way valve 4118 is configured for one-way communication of air flow along a direction for water flow passage 412 (e.g., a top-to-bottom direction shown in Fig. 11). The one-way valve 4118 is arranged between the ventilation hole 4114 and the water flow passage 412 and can effectively prevent the water in the water flow passage 412 from entering the balancing passage 411 to avoid a siphon phenomenon .

[087] In some specific embodiments, as illustrated in Fig. 11, the water flow passage 412 may be U-shaped, and an open end of the U-shaped passage (e.g., an inlet of the water flow passage water 4121 shown in Fig. 11) is connected to the outlet of the drain pump 6, and the other open end of the U-shaped passage (for example, an outlet of the water flow passage 4122 shown in Fig. 11) is configured to drain the water. The balancing passage 411 is connected to an upper part of the water flow passage 412. When the drain pump 6 works, the drain pump 6 pumps water into the inner container assembly 1, and the water enters the flow passage of water 412 through the open end on a left side of the water flow passage 412 and then drains into the sewer through the other end on a right side of the water flow passage 412. The air pressure in the water flow passage 412 Water 412 can be balanced by the ventilation hole 4114 defined in an upper part of the balancing passage 411, so as to avoid the siphon phenomenon when the air pressure in the water flow passage 412 is too low.

[088] Advantageously, at least a part of the balancing passage 411 may be in communication with an upper part of the water flow passage 412 adjacent to an outlet (e.g., an upper part on the right side of the water flow passage 412 adjacent to an outlet). water 412 shown in Fig. 11) and extends vertically. Thus, it is possible to further avoid the siphon phenomenon, prevent water in the water flow passage 412 from entering the balancing passage 411, and enable the balancing passage 411 to reach the pressure equilibrium of the water flow passage 412.

[089] As the balancing passage 411 is connected to the water flow passage 412, the water in the water flow passage 412 inevitably enters the balancing passage 411 during drainage by the drain pump 6. Thus, the balancing passage 411 may be preferably connected to the inner space of the inner vessel assembly 1 for damming, and water entering the balancing passage 411 may flow back to the inner space of the inner vessel assembly 1 and be prevented from accumulating in the balancing passage. balancing passage 411, so as to ensure that the balancing passage 411 can balance the air pressure in the water flow passage 412 effectively.

[090] Furthermore, as illustrated in Fig. 11, the balancing passage 411 may include a first vertical member 4111, a second vertical member 4112, and a horizontal member 4113. The first vertical member 4111 may extend along a direction from top to bottom (e.g., the top to bottom direction shown in Fig. 11), and a lower end of the first vertical member 4111 is in communication with the water flow passage 412 and in communication with an upper end of the passage of water flow 412. The second vertical member 4112 may also extend along the top-to-bottom direction, and a lower end of the second vertical member 4112 is connected to the inner space of the inner container assembly 1. The horizontal member 4113 extends horizontally and is communicated with an upper end of the first vertical member 4111 and an upper end of the second vertical member 4112 correspondingly. For example, the upper end of the first vertical member 4111 is connected and in communication with a right end of the horizontal member 4113, and the upper end of the second vertical member 4112 is connected and in communication with a left end of the horizontal member 4113. When the water in the water flow passage 412 enters the horizontal member 4113 through the first vertical member 4111 due to the siphon phenomenon, water can flow into the inner container assembly 1 through the second vertical member 4112, so that the balancing passage 411 may have a simpler and more reasonable structure and may be convenient for manufacturing.

[091] Advantageously, a lower wall of the horizontal member 4113 may slope downstream in a direction from the first vertical member 4111 to the second vertical member 4112 (e.g., a right-to-left direction shown in Fig. 11) , so that when water enters the horizontal member 4113, the water can automatically flow towards the second vertical member 4112 along the downstream inclined bottom wall, so as to drain the water into the balancing passage 411 effectively.

[092] In some embodiments, as illustrated in Fig. 11, each of the opposing side walls on the second vertical member 4112 is connected to a baffle 4116 with one free end inclined downstream with respect to the horizontal direction, and the baffles 4116 on the two Opposing side walls on the second vertical member 4112 are spaced apart to form a round passage. For example, the baffle 4116 connected to a left side wall of the second vertical member 4112 extends obliquely toward the lower right, while the baffle 4116 connected to a right side wall of the second vertical member 4112 extends obliquely toward the left. bottom, and the baffles 4116 connected to the left and right side walls of the second vertical member 4112 are arranged spaced apart in the top-to-bottom direction. When water flows from the horizontal member 4113 to the second vertical member 4112, the baffles 4116 on the second vertical member 4112 can play a role in guiding the water flow, so that the water quickly flows into the inner container assembly 1. In addition Furthermore, when a fan 42 in the anti-siphon assembly of the fan 4 operates, an air flow in an air supply passage 413 may partially leak into the balancing passage 411, and in this case, the closely spaced and obliquely extending baffles 4116 downstream can effectively prevent air flow from circulating in the balancing passage 411, so as to improve the efficiency of the fan 42 and reduce air leakage.

[093] Since air generally flows in a higher layer compared to water, in order to effectively balance the air pressure in the water flow passage 412, the ventilation hole 4114 in the balancing passage 411 can be set at the top of the balancing passage 411 and, specifically, the ventilation hole 4114 may be formed in an upper wall of the horizontal member 4113. Furthermore, an inner upper surface of the horizontal member 4113 may be provided with a water retaining rib 4115, the water retaining rib 4115 is connected to a side of the vent hole 4114 adjacent to the first vertical member 4111 (e.g., a right side of the vent hole 4114 shown in Fig. 11), and the water retaining rib 4115 may be configured to prevent water in the horizontal member 4113 from flowing through the ventilation hole 4114. Advantageously, in a horizontal projection plane, a projection of the water retaining rib 4115 can completely cover a projection of the ventilation hole 4114 to improve its water retention effect.

[094] In some specific embodiments, the water retention rib 4115 may be L-shaped so that it extends downstream and then away from the first vertical member 4111. In combination with Fig. 11, the water retention rib 4111 water retaining rib 4115 is connected to the right side of the vent hole 4114 and is aligned with a right edge of the vent hole 4114, the water retaining rib 4115 is L-shaped so that it first extends downstream along a vertical direction and then extends to the left along a horizontal direction, and a horizontal extension of the water retaining rib 4115 is vertically opposite the vent hole 4114 and completely protects the vent hole 4114.

When the direction change structure 43 is in the first state, the air supply passage 413 is obstructed from the inner container air inlet 102, while the balancing passage 411 is in communication with the inner container air inlet 102 , in which case the air supply passage 413 is not in the heating chamber with the internal space of the inner container assembly 1, the fan 42 does not operate and the balancing passage 411 is in communication with the internal space of the internal container assembly 1. When the direction change structure 43 is in the second state, the air supply passage 413 is in communication with the inner container air inlet 102 and the balancing passage 411 is obstructed from the inner container air inlet 102, in which case the air supply passage 413 is in communication with the internal space of the inner container assembly 1, while the balancing passage 411 is not in communication with the internal space of the internal container assembly 1, such that fan 42 can blow air into the assembly of internal container 1.

The regenerated water outlet from the water tank 208 is connected to the water inlet passage 322 of the regeneration assembly 32 of the softener 3. The pump drain port 6 is connected to the water flow passage 4121 inlet of the water flow passage 412 of the fan 4 anti-siphon assembly.

[125] A water flow process is presented below. Before the dishwasher 100 operates, water is supplied through the manual water supply port 204 of the water tank 2. Due to the principle of difference between high and low water levels, water flows from the manual water supply chamber 100. water 201 from the water tank 2 to the water drain chamber 202 of the water tank 2 through the resin cavity of the descaling assembly 31 of the descaler 3, up to the water levels in the water supply chamber 201 and the water chamber 201. water drainage 202 be leveled. When the water level detection device 24 detects that the water is sufficient, the water supply is stopped, and in this case the regeneration chamber 203 of the water tank 2 is also filled with water. When the dishwasher 100 begins operating, the drain valve 23 opens and water is supplied for a predetermined time. Since the base water inlet 101 is lower than the drain valve 23, there is a water level difference, and water flows from the water tank 2 towards the base water inlet 101 and to the inner container assembly 1 through of a water pipe from the steam generator 5. After the predetermined time, the water drain valve 23 is closed.

[126] In a water washing process of the dishwasher 100, when the dishwasher 100 rinses the dishes, the water in the water cup 12 of the inner container assembly 1 is pumped and projected by the wash pump 7. water is sprayed to the dishes in the inner container 11 by the upper and lower spray arm mounts 8 (i.e. washing), water droplets flow to the lowest position - the water cup 12, and then the water is pumped out by the pump washing machine 7 to carry out a circular washing process. In the process of pumping the water into the water cup 12 of the inner container 11 by the washing pump 7, the water will be heated by the heating chamber of the heating assembly 9, so that the water will be heated in a circular manner in the washing process and The water in the inner container 11 will be heated slowly overall.

[127] For draining water from the dishwasher 100, after the washing process, the drain pump 6 starts to drain the water into the water cup 12, so that the water is drained from an outlet of the drain pump 6 and enter the water flow passage 412 of the anti-siphon assembly of the fan 4, then the water is drained through the water flow passage outlet 4122 of the water flow passage 412 and flows into the sewer.

[128] For steam sterilization of the dishwasher 100, after a rinsing process, the steam generator 5 is started, water is supplied to the steam generator 5, and the water in the steam generator 5 is rapidly evaporated into steam high temperature. The steam expands to expel water in a water pipe between the steam generator 5 and the base water inlet 101, and then the steam enters the inner container 11 to be sprayed onto the dishes to obtain a sterilization effect of high temperature.

[129] For regeneration of the descaling assembly 31 of the dishwasher 100 (i.e., regeneration of the resin in the resin cavity of the descaling assembly 31 of the descaler 3), after the rinsing process of the dishwasher 100, if established In a regeneration procedure, the switching valve 323 of the regeneration assembly 32 of the water softener 3 is opened and the water in the regeneration chamber 203 of the water tank 2 flows into the saline cavity 321 of the water softener 3 in a relatively low position, under the action of gravity. The water presses upward from the bottom of the salt cavity 321 and is thoroughly mixed with the salt to form saturated brine. Saturated brine enters the resin cavity of the descaling assembly 31 from an upper part of the brine cavity 321 to regenerate the resin. The water originally in the softener resin 3 and the salt cavity 321 is expelled into the water drain chamber 202 of the water tank 2, and the drain valve 23 is opened and the drain pump 6 begins to drain the waste water.
