[0083] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0084] The following combines the attached Figures 1 to 27 Specifically describe the dishwasher 100 according to the embodiment of the present invention.

[0085] As Figure 1 、 Figure 9 And Figure 13 As shown in [relevant figures], the dishwasher 100 according to the embodiment of the present invention includes an inner tank assembly 1 and a water tank 2. Specifically, the water tank 2 has a water tank filling port 204 and a water tank outlet 206 that are interconnected. The water tank filling port 204 is used to inject water into the water tank 2, and the water tank outlet 206 is connected to the inner tank assembly 1.

[0086] Advantageously, the water tank 2 can be provided outside the inner tank assembly 1 to avoid occupying the internal space of the inner tank assembly 1 and ensure the dishwashing efficiency of the inner tank assembly 1. The water tank 2 includes a support portion 26. The support portion 26 supports on the top of the inner tank assembly 1. The upper side of the water tank 2 facing the inner tank assembly 1 is provided with a support portion 26 that protrudes from the side wall surface of the water tank 2. In other words, the support portion 26 is provided at the upper part of the water tank 2, and the support portion 26 is provided on the side of the water tank 2 facing the inner tank assembly 1, and the support portion 26 protrudes from the side wall surface of the water tank. A chamber communicating with the water tank 2 is defined in the support portion 26. After the water tank 2 and the inner tank assembly 1 are assembled, the support portion 26 on the water tank 2 supports on the top of the inner tank assembly 1. Thus, through the cooperation of the support portion and the inner tank assembly, the inner tank assembly is utilized to provide support for the support portion.

[0087] As Figure 9 , the bottom of the support portion 26 on the water tank 2 abuts against the top of the inner tank assembly 1.

[0088] The water tank 2 can be installed on the side wall of the inner container assembly 1 to shorten the distance between the water tank 2 and the inner container assembly 1, facilitating the direct water supply from the water tank 2 to the inner container assembly 1. Preferably, the bottom of the water tank 2 can be higher than the base water inlet 101 of the inner container assembly 1. In this way, without the need for power supply (such as pumping), the water in the water tank 2 can automatically flow towards the base water inlet 101 under the action of gravity and enter the inner container assembly 1, making the structure of the dishwasher 100 simpler, more compact and reasonable.

[0089] Preferably, the bottom of the inner container assembly 1 can be provided with a base water inlet 101, the base water inlet 101 can communicate with the internal space of the inner container assembly 1, and the water tank 2 can be connected to the base water inlet 101 of the inner container assembly 1. That is to say, the water tank 2 communicates with the internal 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 the tableware in the inner container assembly 1.

[0090] The bottom of the water tank 2 is higher than the base water inlet 101 of the inner container assembly 1.

[0091] Combined Figure 1 and Figure 2 , a receiving groove is formed on one side of the water tank 2 facing the inner container assembly, and one end of the inner container assembly 1 is received in the receiving groove. Further, one end of the inner container assembly 1 can be received in the receiving groove. In addition, a relief notch that is adapted to the outer side of the top wall of the inner container assembly 1 and is open at the front side is provided on the support portion 26.

[0092] As Figure 4 and Figure 13 , the water tank water filling port 204 is formed at the top of the water filling cavity 201, and the water tank water filling port 204 is closed by a filter net. The filter net can filter out 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, thus ensuring the washing effect on the tableware.

[0093] Preferably, as Figure 7 and Figure 13 shown, a water level detection device 24 is provided in the water tank 2. For example, the water level detection device 24 can be a water level sensor. Specifically, the water level sensor can be used to detect the water level in the water tank 2. Thus, the degree of automation of the dishwasher 100 can be improved, facilitating the real-time monitoring of the water level in the water tank 2. For example, when the water level sensor detects that the water level in the water outlet cavity 202 reaches a predetermined level, a signal can be fed back to the control component, and the control component can control the system to stop injecting water into the water outlet cavity 202 to prevent the water tank 2 from overflowing and achieve the purpose of saving water.

[0094] As Figure 7 shown, the water level sensor is provided on the top wall of the water tank 2.

[0095] Preferably, as Figure 13 shown, a water tank drain valve 23 may be provided at the bottom of the water tank 2. The water tank drain valve 23 may be connected to the bottom of the water tank 2 and the bottom of the inner tank assembly 1 respectively. The water tank drain valve 23 is a manual valve or an electric valve. By controlling the opening and closing of the water tank drain valve 23, it is possible to control whether the water tank 2 and the inner tank assembly 1 are connected, so as to conveniently control whether to supply water to the inner tank assembly 1.

[0096] As Figure 1 , Figure 9 and Figure 13 shown, a through hole 14 is formed on the inner tank assembly 1. The water tank 2 has a water tank water filling port 204, a water tank water outlet 206 and an overflow port 209 that are communicated with each other. The overflow port 209 is higher than the through hole 14, and the overflow port 209 is communicated with the through hole 14 and is adapted to allow water to flow from the overflow port 209 into the through hole 14. In other words, the dishwasher 100 mainly includes an inner tank assembly 1 and a water tank 2. The inner tank assembly 1 is connected to the water tank 2. Among them, a through hole 14 is provided on the inner tank assembly 1, and a water tank water filling port 204, a water tank water outlet 206 and an overflow port 209 are provided on the water tank 2. The water tank water filling port 204, the water tank water outlet 206 and the overflow port 209 are all communicated with the inner cavity of the water tank 2. After the inner tank assembly 1 and the water tank 2 are assembled, the water tank water outlet 206 is communicated with the inner tank assembly 1, so as to supply water into the inner tank assembly 1. The height of the overflow port 209 of the water tank 2 is higher than the through hole 14 of the inner tank assembly 1, and the overflow port 209 of the water tank 2 is communicated with the through hole 14 of the inner tank assembly 1.

[0097] If water is injected into the water tank 2 through the water tank water filling port 204, as the water level in the water tank 2 rises, the water in the water tank 2 can flow to the inner tank assembly 1 through the overflow port 209 and the through hole 14. That is, the water tank 2 has an anti-overflow effect, which can prevent the water tank 2 from being damaged due to being in a full water state and a sudden increase in water pressure.

[0098] Specifically, when automatically filling water, if the water inlet valve of the dishwasher 100 is damaged, it is easy to cause water to continuously enter the water tank 2 of the dishwasher 100. Since the through hole 14 is located at a lower position than the water tank water filling port 204, when overflow occurs, the water will flow out from the through hole 14 of the water tank 2 and flow into the water cup 12 of the machine inner tank 11, preventing the water from flowing out from the water tank water filling port 204; when the water exceeds the water level detection line of the water tank 2, the drain pump can be started to drain the water, and the water flowing into the inner tank assembly 1 is drained, so as to prevent the water from overflowing the dishwasher 100 and flooding the kitchen.

[0099] Thus, for the dishwasher 100 according to the embodiments of the present invention, by providing an overflow port 209 on the water tank 2, providing a through hole 14 on the inner tank assembly 1, and setting the height of the overflow port 209 to be higher than that of the through hole 14, the water in the water tank 2 can flow into the inner tank assembly 1 through the overflow port 209, realizing the drainage of the water in the water tank 2, avoiding damage to the water tank 2 and the components thereon, and thus ensuring the use reliability of the dishwasher 100.

[0100] Optionally, the overflow port 209 is provided at the upper part of the water tank 2 and lower than the water filling port 204 of the water tank. Specifically, when the water level in the water tank 2 is higher than the height of the overflow port 209, the water in the water tank 2 will flow out through the overflow port 209 and flow into the inner cavity of the inner tank assembly 1 through the through hole 14 on the inner tank assembly 1. At this time, if water continues to be injected into the water tank 2, the water in the water tank 2 will continuously flow into the inner tank assembly 1, ensuring that the water level in the water tank 2 can always be maintained at the height position of the overflow port 209. The height of the overflow port 209 is lower than the water filling port 204 of the water tank, which is conducive to realizing the overflow effect, ensuring the dynamic balance of the water level in the water tank 2, preventing the water tank 2 and the components thereon from bursting due to being in a full water state for a long time, and extending the service life of the water tank 2.

[0101] Among them, according to an embodiment of the present invention, the water tank 2 is installed on the inner tank assembly 1, and the overflow port 209 and the through hole 14 are vertically opposite. For example, the water tank 2 can be installed on the side wall of the inner tank assembly 1. A through hole 14 is provided on the top wall or side wall of the inner tank assembly 1 facing the water tank 2. An overflow port 209 is provided on the side of the water tank 2 facing the inner tank assembly 1, and the overflow port 209 is located above the through hole 14. When the water tank 2 is filled with water, the water flows out of the water tank 2 through the overflow port 209 and then flows into the inner cavity of the inner tank assembly 1 through the through hole 14 of the inner tank assembly 1. Thus, by vertically opposing the overflow port 209 and the through hole 14, the water flows from the water tank 2 into the inner cavity of the inner tank assembly 1 under the action of gravity, reducing the water flow path, and thus avoiding damage to the water tank 2 and the components thereon.

[0102] In some specific embodiments of the present invention, the overflow port 209 is formed on the support portion 26, and the through hole 14 is formed on the top surface of the inner tank assembly 1.

[0103] Specifically, as Figure 9 shown, the water tank 2 is along the vertical direction (such as Figure 9extends in the vertical direction (as shown) and is provided on the rear wall of the inner tank assembly 1. An overflow port 209 communicating with the chamber is provided on the support portion 26. A through hole 14 is provided on the top surface of the inner tank assembly 1. After the water tank 2 is assembled with the inner tank assembly 1, the bottom of the support portion 26 on the water tank 2 abuts against the top of the inner tank assembly 1, and the overflow port 209 is located above the through hole 14, that is, a through hole 14 is provided on one side of the inner tank assembly 1 facing the support portion 26. After the water tank 2 is filled with water, the water can flow into the support portion 26 through the overflow port 209, and then enter the inner cavity of the inner tank assembly 1 through the through hole 14 at the top of the inner tank assembly 1.

[0104] Wherein, the water tank 2 is further connected with a water inlet valve. The water tank 2 is connected with the water inlet valve. When it is necessary to inject water into the water tank 2, the water inlet valve can be opened, and tap water can enter the water tank 2 through the water inlet valve in sequence. When the water tank 2 is full (or reaches a predetermined water level), the water inlet valve can be closed. Thus, it is possible to control whether the water circuit system is connected to an external water source through the water inlet valve, and the operation is simple and convenient.

[0105] According to an embodiment of the present invention, an outlet chamber 202 and a water filling chamber 201 are defined in the water tank 2. A water tank water filling port 204 is provided at the top of the water filling chamber 201, and a water tank water outlet 206 is provided at the bottom of the outlet chamber 202.

[0106] Specifically, as Figure 4 and Figure 13 shown, a first partition 21 may be provided in the water tank 2. The first partition 21 and the inner wall of the water tank 2 respectively define the outlet chamber 202 and the water filling chamber 201. The outlet chamber 202 and the water filling chamber 201 are arranged at intervals in the horizontal direction (for example, Figure 13 the left-right direction shown in Figure 13 ). The water tank water filling port 204 is formed at the top of the water filling chamber 201, and the water tank water outlet 206 is provided at the bottom of the outlet chamber 202. Combining

[0107] advantageously, the dishwasher further includes a water softener 3. The inlet of the water softener 3 is respectively communicated with the water filling chamber 201 and the water inlet valve, and the outlet of the water softener 3 is communicated with the outlet chamber 202. Wherein, the water softener 3 has one or two inlets respectively connected to the water filling chamber 201 and the water inlet valve and communicating with each other.

[0108] Specifically, as Figures 14 to 25, the water softener 3 has an outlet (i.e., the water softener outlet 303) and two inlets (i.e., the water softener inlets, such as the first water softener inlet 301 and the second water softener inlet 302 shown below). The water softener outlet 303 and the water softener inlets are both connected to the water softening components inside the water softener 3. The water softener outlet 303 of the water softener 3 is connected to the water outlet chamber 202 of the water tank 2 for inputting softened water into the water outlet chamber 202 of the water tank 2. That is to say, water enters the water softener 3 from the water softener inlets, is softened by the water softening components in the water softener 3, calcium, magnesium and other ions in the water are removed, and the obtained pure water enters the water outlet chamber 202 of the water tank 2 from the water softener outlet 303, and then flows from the water outlet chamber 202 to the inner tank assembly 1 for washing tableware. Thus, scale formation inside the inner tank assembly 1 and in the water outlet chamber 202 of the water tank 2 can be avoided, thereby further improving the washing effect of the dishwasher 100 and enhancing the user experience of the dishwasher 100.

[0109] Thus, by providing the water tank 2 for supplying water to the inner tank assembly 1, the dishwasher 100 can supply water to the inner tank assembly 1 by manually adding water to the water tank 2, improving applicability. In addition, the water softener 3 is connected in series in the water circuit system, which can soften the water quality and effectively prevent scale from accumulating in the inner tank assembly 1 and the water outlet chamber 202, enhancing the dishwashing effect.

[0110] Among them, a flow meter 34 is connected in series between the water inlet valve and the water softener 3. That is to say, a flow meter 34 is provided between the inlet of the water softener 3 and the water inlet valve, that is, the flow meter 34 is arranged on the water circuit between the inlet of the water softener 3 and the water inlet valve, so as to conveniently detect the flow rate of the water flowing into the water softener 3.

[0111] Specifically, the connection route of the water circuit system of the dishwasher 100 is as follows: the water inlet pipe is connected to the faucet, the water inlet valve is connected to the water inlet pipe, the water pipe is connected to the water inlet valve and the flow meter 34, the flow meter 34 and the water softener inlet of the water softener 3, the water pipe is connected to the water softener outlet 303 of the water softener 3 and the water tank soft water inlet 207 of the water tank 2, the air inlet hole of the water tank 2 is hermetically connected to the inner tank air outlet hole. If the water inlet valve of the dishwasher 100 is damaged, it is easy to cause water to continuously enter the water tank 2 of the dishwasher 100. Since the through hole 14 is located at the lower position of the water tank filling port 204, when overflow occurs, the water will flow out from the through hole 14 of the water tank 2 to prevent water from flowing out from the water tank filling port 204; when the water exceeds the water level detection line of the water tank 2, the flow meter 34 detects that the water inlet exceeds the standard, and the drain pump can be started to drain the water, draining the water flowing into the inner tank assembly 1 to avoid water overflowing from the dishwasher 100 and flooding the kitchen.

[0112] Next, refer to the attached Figures 1 to 25 and Figure 27 Describe the dishwasher 100 according to a specific embodiment of the present invention.

[0113] The dishwasher 100 according to an embodiment of the present invention includes: an inner container assembly 1, a water tank 2, and a water softener 3.

[0114] Specifically, as Figure 12 and Figure 13 The water tank 2 has a water tank outlet chamber 202. The outlet chamber 202 of the water tank 2 is connected to the inner container assembly 1. The outlet chamber 202 of the water tank 2 is used to supply water into the inner container assembly 1 for washing the tableware in the inner container assembly 1. And the water required for a complete washing process of the dishwasher 100 can be stored in the outlet chamber 202. In this way, not only can the water entering the outlet chamber 202 be controlled by a water inlet valve or the like, but also water can be manually added into the outlet chamber 202. Thus, multiple ways can be realized to supply water to the inner container assembly 1 of the dishwasher 100, improving the applicability. It is applicable to areas without tap water or when using an external water source to supply water to the dishwasher 100 in case of sudden water cut-off. In addition, since the water tank 2 can pre-store the water for dishwashing, the dishwashing process is not affected by the external water injection speed, thereby further improving the dishwashing efficiency of the dishwasher 100.

[0115] Such as Figures 14 to 25 , the water softener 3 has a water softening assembly 31, and the water softener 3 has a water softener outlet 303 and a water softener inlet (such as the first water softener inlet 301 and the second water softener inlet 302 shown below). Both the water softener outlet 303 and the water softener inlet are communicated with the water softening assembly 31. The water softener outlet 303 of the water softener 3 is connected to the water tank outlet chamber 202 for inputting softened water into the outlet chamber 202. That is to say, water enters the water softener 3 from the water softener inlet, is softened by the water softening assembly 31 in the water softener 3, calcium, magnesium and other ions in the water are removed, and the obtained pure water enters the water tank outlet chamber 202 from the water softener outlet 303, and then flows from the outlet chamber 202 to the inner container assembly 1 for washing tableware. Thus, scale formation inside the inner container assembly 1 and in the water tank outlet chamber 202 can be avoided, thereby further improving the washing effect of the dishwasher 100 and enhancing the use experience of the dishwasher 100.

[0116] For the dishwasher 100 according to an embodiment of the present invention, by providing the water tank 2 for supplying water to the inner container assembly 1, the dishwasher 100 can supply water to the inner container assembly 1 by manually adding water to the water tank 2, improving the applicability. In addition, the water softener 3 is connected in series in the water circuit system, which can soften the water quality and effectively prevent scale from accumulating in the inner container assembly 1 and the outlet chamber 202, enhancing the dishwashing effect.

[0117] In an embodiment of the present invention, the dishwasher may further include a water inlet valve. The water softener water inlet is connected to the water inlet valve. When dishwashing is required or when it is necessary to inject water into the water outlet cavity 202, the water inlet valve can be opened, and tap water can enter the water softening assembly 31 for softening successively through the water inlet valve and the water softener water inlet. When the dishwashing is finished or the water in the water outlet cavity 202 is filled (or reaches a predetermined water level), the water inlet valve can be closed. Thus, it is possible to control whether the water circuit system is connected to an external water source through the water inlet valve, and the operation is simple and convenient.

[0118] In some embodiments, the water tank may further include a water filling cavity 201. The water filling cavity 201 may have a water tank water filling port 204. The water softener water inlet (such as the second water softener water inlet 302 described below) is connected to the water filling cavity 201. When manual water filling is required, the user can add water into the water filling cavity 201 through the water tank water filling port 204. The water in the water filling cavity 201 then enters the water softener 3 for softening through the water softener water inlet, and the pure water flowing out of the water softener 3 then enters the inner tank assembly 1 of the water outlet cavity 202 for dishwashing.

[0119] In other embodiments, the water circuit system may further include a water inlet valve and a water filling cavity 201 at the same time. The water filling cavity 201 has a water tank water filling port 204. The water softener water inlet is respectively connected to the water inlet valve and the water filling cavity 201. The water softener water inlet may include only one that is connected to both the water inlet valve and the water filling cavity 201, or the water softener 3 water inlet may also include two that are respectively connected to the water inlet valve and the water filling cavity 201. That is to say, when the water softener water inlet is one, the water softener water inlet, the water inlet valve, and the water filling cavity 201 are connected in series; when the water softener water inlet is two, one water softener water inlet (such as the first water softener water inlet 301) is connected in series with the water inlet valve. For example, external tap water can enter the water softening assembly 31 successively through the water inlet valve and the first water softener water inlet 301. At this time, the water supply method is tap water supply. The other water softener water inlet (the second water softener water inlet 302) is connected in series with the water filling cavity 201. For example, the user can add water into the water filling cavity 201 through the water tank water filling port 204, and the water then enters the water softening assembly 31 of the water softener 3 through the second water softener water inlet 302. At this time, the dishwasher 100 adopts a manual water supply method. That is to say, there is a water softener water inlet corresponding to each of the two methods of automatic tap water filling and manual water filling. Thus, the structure of the water circuit system can be simplified, which is convenient for connecting external pipelines.

[0120] In some embodiments, such as Figure 12 and Figure 13 , a first partition 21 may be provided in the water tank 2. The first partition 21 defines a water outlet cavity 202 and a water filling cavity 201 in the water tank 2. The water outlet cavity 202 and the water filling cavity 201 are in the horizontal direction (such as Figure 13They are arranged at intervals in the left - right direction (as shown), the water tank filling port 204 is formed at the top of the filling cavity 201, and the bottom of the filling cavity 201 is connected to the water softener inlet. Combining Figure 7 , the water tank filling port 204 is formed on the left side at the top of the water tank 2. The first partition 21 is arranged in the water tank 2 and is located on the right side of the water tank filling port 204. In the vertical direction from top to bottom, at least a part of the first partition 21 is in the shape of a plate extending obliquely from right to left. The first partition 21 divides the space in the water tank 2 into a left - hand filling cavity 201 and a right - hand water outlet cavity 202, and the bottom of the filling cavity 201 and the bottom of the water outlet cavity 202 can be communicated. When the bottom of the filling cavity 201 and the bottom of the water outlet cavity 202 are not communicated, the bottom of the filling cavity 201 is connected to the water softener inlet.

[0121] Preferably, the first partition 21 extends from bottom to top to be adjacent to the top of the water tank 2, that is to say, the top of the filling cavity 201 and the top of the water outlet cavity 202 are communicated. In this way, when the water outlet cavity 202 injects water into the inner tank assembly 1, the air pressure in the water outlet cavity 202 decreases. At this time, external air can enter the water outlet cavity 202 through the water tank filling port 204 and the top of the first partition 21, so as to balance the air pressure and achieve the effect of ventilation. Of course, when injecting water into the water outlet cavity 202, the pressure in the water outlet cavity 202 increases, and the air flow in the water outlet cavity 202 can also be discharged through the water tank filling port 204.

[0122] In some embodiments, the water softening component 31 in the water softener 3 includes a resin cavity filled with resin. After the resin softens the calcium and magnesium ions in the water quality, regeneration is required. Preferably, as Figure 18 and Figure 19 shown, the water softener 3 can also have a regeneration component 32 for regenerating the water softening component 31. The regeneration component 32 can include a salt cavity 321, a water inlet channel 322 and a switching valve 323. The salt cavity 321 is connected to the water softening component 31, the water inlet channel 322 is connected to the salt cavity 321, and the switching valve 323 is used to open or close the water inlet channel 322. When the water softening component 31 needs to be regenerated, the switching valve 323 can be opened, water can enter the salt cavity 321 to form a saturated salt solution, and then the salt solution enters the water softening component 31 to regenerate the water softening component 31.

[0123] Advantageously, as Figure 13 shown, a second partition 22 can be arranged in the water tank 2. The second partition 22 defines a regeneration cavity 203 in the water tank 2 that is spaced apart from the water outlet cavity 202. The upper part of the regeneration cavity 203 is communicated with the water outlet cavity 202. Combining Figure 7, the second partition 22 extends upward from the bottom wall of the water tank 2 and is spaced apart from the top wall of the water tank 2. The left side of the second partition 22 is the water outlet chamber 202 and the right side is the regeneration chamber 203. The connection between the regeneration chamber 203 and the water outlet chamber 202 is not higher than the highest water level of the water outlet chamber 202. That is to say, when the water level in the water outlet chamber 202 gradually rises to exceed the height of the second partition 22 (at this time, it has not reached the highest water level of the water outlet chamber 202), the water in the water outlet chamber 202 can overflow over the second partition 22 and enter the regeneration chamber 203. The bottom of the regeneration chamber 203 is connected to the water inlet channel 322, so that water can be injected into the salt chamber 321 through the water inlet channel 322 to form a saturated salt solution for regenerating the soft water component 31.

[0124] Preferably, a salt adding hole 325 communicating with the salt chamber 321 can be provided on the water softener 3. The salt adding hole 325 is opened or closed by a lid, and a salt shortage detection device 324 is also provided on the salt chamber 321. When the salt shortage detection device 324 detects that the salt in the salt chamber 321 is insufficient (not enough to form a saturated salt solution), the user can open the lid and add salt into the salt chamber 321 through the salt adding hole 325 to ensure that the soft water component 31 can be effectively regenerated.

[0125] Preferably, an air inlet pipe 25 can be provided in the water tank 2. One end of the air inlet pipe 25 (for example, Figure 13 the upper end of the air inlet pipe 25 shown in Figure 13 ) communicates with and closes the water tank air inlet 205, and the other end of the air inlet pipe 25 (for example,

[0126] the lower end of the air inlet pipe 25 shown in

[0127] Preferably, as shown in Figure 5 and Figure 27As shown, the dishwashers 100 of the above embodiments of the present invention may further include: a steam generator 5, which is connected in series between the water outlet chamber 202 of the water tank and the inner container assembly 1. The steam generator 5 is used to supply water or high-temperature steam to the inner container assembly 1. For example, during the dishwashing process of the dishwasher 100, the water in the water outlet chamber 202 of the water tank 2 first enters the steam generator 5 and then enters the inner container assembly 1. At this time, the steam generator 5 is only a channel for water circulation; when the dishwashing process is completed and it is necessary to disinfect the inner container assembly 1 and the tableware in the inner container assembly 1 using the steam generator 5, the water in the water outlet chamber 202 enters the steam generator 5, and the steam generator 5 heats the water to form gaseous high-temperature steam. The high-temperature steam enters the inner container assembly 1, and the dishwasher 100 can be sterilized and disinfected. Thus, the washing effect and washing efficiency of the dishwasher 100 can be further improved, and at the same time, the dishwasher 100 is also provided with the ability of sterilization and disinfection.

[0128] The dishwasher 100 according to an embodiment of the present invention includes a spray arm assembly 8, a washing pump 7, and a drainage pump 6. Specifically, the spray arm assembly 8 is disposed inside the inner container assembly 1. The washing pump 7 is respectively connected to the inner container assembly 1 and the spray arm assembly 8. The washing pump 7 is used to pump the water in the inner container assembly 1 to the spray arm assembly 8. The drainage pump 6 is connected to the inner container assembly 1 and is used to drain the water in the inner container assembly 1.

[0129] Specifically, the water tank 2 is connected to the inner container assembly 1. The water tank 2 is used to supply water to the inner container assembly 1. The water tank 2 has a water tank filling port 204, and the user can manually add water into the water tank 2 through the water tank filling port 204. Of course, the water tank 2 can also adopt a non-manual water addition mode. For example, the user can directly connect the water tank 2 to the water supply pipe and supply water to the water tank 2 directly through the water supply pipe. The spray arm assembly 8 is disposed inside the inner container assembly 1; the washing pump 7 is respectively connected to the inner container assembly 1 and the spray arm assembly 8, and the washing pump 7 is used to pump the water in the inner container to the spray arm assembly 8; the drainage pump 6 is connected to the inner container assembly 1, and the drainage pump 6 is used to drain the water in the inner container assembly 1.

[0130] When it is necessary to clean the tableware using the dishwasher 100, first, the user can choose to manually add water to the water tank 2 or directly supply water to the water tank 2 using tap water. When the water addition is completed or during the water addition process, the water in the water tank 2 flows into the inner container assembly 1. Under the action of the washing pump, the washing pump 7 pumps the water in the inner container assembly 1 to the spray arm assembly 8, and the spray arm assembly 8 sprays the water onto the tableware to be cleaned, realizing the washing of the tableware. When the spraying is over, the drainage pump 6 is used to drain the water in the inner container assembly 1.

[0131] Since the dishwasher 100 according to the embodiments of the present invention has the above technical effects, the dishwasher 100 according to the embodiments of the present application also has the above technical effects, that is, by adding a water tank 2 and providing a water tank filling port 204 on the water tank 2, it is possible to manually add water into the dishwasher 100 for washing tableware, thereby improving the applicability of the dishwasher 100. By connecting a water softener 3 in series in the water circuit system, the water quality can be softened, effectively avoiding the accumulation of scale in the inner tank assembly 1 and the water outlet cavity 202, enhancing the dishwashing effect and improving the overall performance.

[0132] Reference is made below to Figures 1 - 26 describe the dishwasher 100 according to the embodiments of the present invention.

[0133] The dishwasher 100 according to the embodiments of the present invention includes: an inner tank assembly 1, a water tank 2, a spray arm assembly 8, a washing pump 7, and a drainage pump 6. Specifically, the water tank 2 is connected to the inner tank assembly 1. The water tank 2 is used to supply water into the inner tank assembly 1. The water tank 2 has a water tank filling port 204, and the user can manually add water into the water tank 2 through the water tank filling port 204. Of course, the water tank 2 can also adopt a non-manual water filling mode. For example, the user can directly connect the water tank 2 to the water supply pipe and directly supply water to the water tank 2 through the water supply pipe.

[0134] When it is necessary to clean tableware using the dishwasher 100, first, the user can choose to manually add water to the water tank 2 or directly supply water into the water tank 2 using tap water. After the water filling is completed or during the water filling process, the water in the water tank 2 flows into the inner tank assembly 1. Under the action of the washing pump 7, the washing pump 7 pumps the water in the inner tank assembly 1 to the spray arm assembly 8, and the spray arm assembly 8 sprays the water onto the tableware to be cleaned, realizing the washing of the tableware. After the spraying is completed, the drainage pump 6 is used to drain the water in the inner tank assembly 1.

[0135] In some embodiments, an inner tank air inlet 102 and an inner tank air outlet can be provided on the inner tank assembly 1. When the pressure in the inner tank assembly 1 is too high, the air in the inner tank assembly 1 can flow out through the inner tank air outlet. When the air pressure in the inner tank assembly 1 is too low, external air can enter the interior of the inner tank 11 through the inner tank air inlet 102 to balance the air pressure inside and outside the inner tank assembly 1. Further, a water tank air inlet 205 can be provided on the water tank 2, and the water tank air inlet 205 is communicated with the inner tank air outlet. In this way, when the air pressure in the inner tank assembly 1 is too high, the air in the inner tank assembly 1 can enter the water tank 2 successively through the inner tank air outlet and the water tank air inlet 205. Thus, the pressure difference between the water tank 2 and the inner tank assembly 1 can be balanced, and the air pressure in the water tank 2 can be balanced with the external atmospheric pressure through the water tank filling port 204.

[0136] Preferably, an air inlet pipe 25 can be provided in the water tank 2. One end of the air inlet pipe 25 (for example Figure 13The upper end of the intake pipe 25 shown in [the figure] is connected to and closes the water tank air inlet 205, and the other end of the intake pipe 25 (for example, Figure 13 the lower end of the intake pipe 25 shown in [the figure]) extends to the lower part inside the water tank 2. In this way, when the water in the water tank 2 is injected into the inner tank assembly 1 and the air pressure in the water tank 2 decreases, the external air can enter the water tank 2 through the intake pipe 25, thereby balancing the air pressure inside and outside the water tank 2 to ensure that the water in the water tank 2 can flow smoothly to the inner tank assembly 1.

[0137] In some embodiments of the present invention, the dishwasher 100 may further include a fan anti-siphon assembly 4. The fan anti-siphon assembly 4 may include: a body portion 41. The body portion 41 has a water flow channel 412 and a balance channel 411. One end of the water flow channel 412 (for example, Figure 11 the left end of the water flow channel 412 shown in [the figure]) is connected to the outlet of the drainage pump 6, and the other end of the water flow channel 412 (for example, Figure 11 the right end of the water flow channel 412 shown in [the figure]) is used for drainage. When the dishwasher 100 drains water, the drainage pump 6 works, and the water in the inner tank assembly 1 enters the water flow channel 412 through the drainage pump 6 and is discharged through the water flow channel 412 (for example, discharged to the sewer). Further, the balance channel 411 may be connected to the water flow channel 412, and the balance channel 411 has a ventilation hole 4114 for balancing the air pressure inside and outside the water flow channel 412.

[0138] Advantageously, as Figure 11 shown, a check valve 4118 for unidirectionally conducting the air flow in the direction towards the water flow channel 412 (for example, Figure 11 the direction from top to bottom shown in [the figure]) is provided in the balance channel 411. The check valve 4118 is arranged between the ventilation hole 4114 and the water flow channel 412, and the check valve 4118 can effectively prevent the water in the water flow channel 412 from entering the balance channel 411 and prevent the occurrence of siphon phenomenon.

[0139] In some specific embodiments, as Figure 11 shown, the water flow channel 412 may be U-shaped. One open end of the U-shaped channel (for example, Figure 11 the water flow channel inlet 4121 shown in [the figure]) is connected to the outlet of the drainage pump 6, and the other open end of the U-shaped channel (for example, Figure 11 the water flow channel outlet 4122 shown in [the figure]) is used for drainage. The balance channel 411 is connected to the upper part of the water flow channel 412. When the drainage pump 6 works, the drainage pump 6 pumps out the water in the inner tank assembly 1. The water enters the water flow channel 412 through the open end on the left side of the water flow channel 412, and then is discharged to the sewer from the open end on the right side of the water flow channel 412. And through the ventilation hole 4114 arranged at the top of the balance channel 411, the air pressure in the water flow channel 412 can be balanced to avoid the occurrence of siphon phenomenon due to too low air pressure in the water flow channel 412.

[0140] Advantageously, at least a portion of the balance channel 411 can communicate with and extend upwardly from the upper side of the water flow channel 412 near the outlet (e.g., Figure 11 the upper part on the right side of the water flow channel 412 as shown). Thereby, siphon phenomenon can be further avoided, preventing the water in the water flow channel 412 from entering the balance channel 411, while also achieving the effect of balancing the air pressure in the water flow channel 412 by the balance channel 411.

[0141] Since the balance channel 411 is connected to the water flow channel 412, during the process of the drainage pump 6 draining water, inevitably, the water in the water flow channel 412 will enter the balance channel 411. Therefore, preferably, the balance channel 411 can be connected to the internal space of the inner tank assembly 1 for returning water, so that the water entering the balance channel 411 can flow back into the internal space of the inner tank assembly 1, avoiding the accumulation of water in the balance channel 411 and ensuring that the balance channel 411 can effectively balance the air pressure in the water flow channel 412.

[0142] Furthermore, as Figure 11 shown, the balance channel 411 can include: a first vertical limb 4111, a second vertical limb 4112, and a horizontal limb 4113. The first vertical limb 4111 can extend in the up and down direction (e.g., Figure 11 the up and down direction as shown), and the lower end of the first vertical limb 4111 communicates with the water flow channel 412, and the lower end of the first vertical limb 4111 communicates with the upper end of the water flow channel 412; the second vertical limb 4112 can also extend in the up and down direction, and the lower end of the second vertical limb 4112 is connected to the internal space of the inner tank assembly 1; the horizontal limb 4113 extends horizontally and communicates with the upper end of the first vertical limb 4111 and the upper end of the second vertical limb 4112 respectively. For example, the upper end of the first vertical limb 4111 is connected to and communicates with the right end of the horizontal limb 4113, and the upper end of the second vertical limb 4112 is connected to and communicates with the left end of the horizontal limb 4113. When the water in the water flow channel 412 enters the horizontal limb 4113 due to siphon phenomenon through the first vertical limb 4111, the water can flow into the inner tank assembly 1 through the second vertical limb 4112. Thereby, the structure of the balance channel 411 can be made simpler and more reasonable, and it is also convenient for processing and manufacturing.

[0143] Advantageously, the bottom wall of the horizontal limb 4113 can be configured to be downwardly inclined in the direction from the first vertical limb 4111 to the second vertical limb 4112 (e.g., Figure 11 the direction from right to left as shown). In this way, when water enters the horizontal limb 4113, the water can automatically flow along the downwardly inclined bottom wall towards the second vertical limb 4112, thereby effectively draining all the water in the balance channel 411.

[0144] In some embodiments, asFigure 11 As shown, baffles 4116 that are inclined downward at the free ends relative to the horizontal direction are connected to opposite side walls within the second vertical limb 4112, and the baffles 4116 on the opposite side walls within the second vertical limb 4112 are arranged in a staggered manner to form a tortuous channel. For example, the baffle 4116 connected to the left side wall of the second vertical limb 4112 extends obliquely downward to the right, and the baffle 4116 connected to the right side wall of the second vertical limb 4112 extends obliquely downward to the left, and the baffles 4116 connected to the left side wall and the right side wall of the second vertical limb 4112 are arranged in a staggered manner in the vertical direction. When water flows from the horizontal limb 4113 to the second vertical limb 4112, the baffles 4116 within the second vertical limb 4112 can play an effect of guiding the water flow, enabling the water flow to quickly flow towards the inner tank assembly 1. In addition, when the blower 42 in the blower anti-siphon assembly 4 operates, part of the air flow in the air supply channel 413 will leak into the balance channel 411. At this time, the staggered and obliquely downward extending baffles 4116 can effectively block the air flow from flowing within the balance channel 411, thereby improving the efficiency of the blower 42 and reducing the air flow leakage amount.

[0145] Since air generally flows in the upper layer compared to water, in order to effectively balance the air pressure within the water flow channel 412, the ventilation holes 4114 within the balance channel 411 can be provided at the top of the balance channel 411. Specifically, the ventilation holes 4114 can be formed on the top wall of the horizontal limb 4113. Further, a water retaining rib 4115 can be provided on the top surface within the horizontal limb 4113, and the water retaining rib 4115 is connected to the side (such as Figure 11 the right side of the ventilation hole 4114 shown) adjacent to the first vertical limb 4111 of the ventilation hole 4114. The water retaining rib 4115 can be used to block the water in the horizontal limb 4113 from flowing out through the ventilation hole 4114. Advantageously, in the horizontal projection plane, the projection of the water retaining rib 4115 can completely cover the projection of the ventilation hole 4114 to improve its water blocking effect.

[0146] In some specific embodiments, the water retaining rib 4115 can be in an L shape that first extends downward and then extends away from the first vertical limb 4111. Combining Figure 11 , the water retaining rib 4115 is connected to the right side of the ventilation hole 4114, and the water retaining rib 4115 is flush with the right edge of the ventilation hole 4114. The water retaining rib 4115 is in an L shape that first extends in the vertically downward direction and then extends in the horizontal direction to the left, and the horizontal extension section of the water retaining rib 4115 is vertically opposite to the ventilation hole 4114 and completely blocks the ventilation hole 4114.

[0147] According to some embodiments of the present invention, such as Figure 5 , Figure 6 and Figure 11As shown, the liner assembly 1 may have an liner air inlet 102 and an liner air outlet, the balancing channel 411 is connected to the liner air inlet 102, and the main body 41 is further provided with an air supply channel 413 connected to the liner air inlet 102, that is, the balancing channel 411 and the air supply channel 413 are both connected to the liner air inlet 102. The fan 42 can deliver air to the liner 11 through the air supply channel 413.

[0148] The fan anti-siphon assembly 4 may further include: a fan 42 and a reversing structure 43. The fan 42 is disposed on the main body 41. The fan 42 is opposite to the air supply channel 413. Furthermore, the air supply port of the fan 42 is opposite to the entrance of the air supply channel 413. The fan 42 is used to supply air into the air supply channel 413. The wind can pass through the air supply channel 413 and enter the inner tank assembly 1 through the inner tank air inlet 102.

[0149] The reversing structure 43 is disposed in the main body 41, and the reversing structure 43 can be switched between a first state and a second state. When the reversing structure 43 is in the first state, the air supply channel 413 is blocked from the inner liner air inlet 102 and the balancing channel 411 is connected to the inner liner air inlet 102. At this time, the air supply channel 413 is not connected to the internal space of the inner liner assembly 1, and the fan 42 does not work, while the balancing channel 411 is connected to the internal space of the inner liner assembly 1. When the reversing structure 43 is in the second state, the air supply channel 413 is connected to the inner liner air inlet 102 and the balancing channel 411 is blocked from the inner liner air inlet 102. At this time, the air supply channel 413 is connected to the internal space of the inner liner assembly 1, and the balancing channel 411 is not connected to the internal space of the inner liner assembly 1, and the fan 42 can supply air to the inner liner assembly 1.

[0150] Furthermore, if Figure 11 As shown, the main body 41 may further include a connecting channel 414, the top surface of the connecting channel 414 is connected to the balancing channel 411, and the side surface of the connecting channel 414 is connected to the air supply channel 413, the reversing structure 43 is a baffle disposed in the connecting channel 414, the upper end of the baffle is hinged to the top of the air supply channel 413, so that the baffle can rotate around the hinge position, the reversing structure 43 closes the entrance of the balancing channel 411 in the second state, and when the reversing structure 43 is in the first state, the baffle closes the outlet of the air supply channel 413, and the reversing structure 43 moves from top to bottom along the air outlet direction of the air supply channel 413 (for example Figure 11 from right to left in the middle).

[0151] It should be noted that when the blower 42 operates, the blower 42 can send air into the air supply channel 413. Since the partition is hinged and the partition is inclined along the air outlet direction of the air supply channel 413, the blower 42 can easily blow up the partition, so that the partition separates the communication channel 414 from the balance channel 411, and at this time the air supply channel 413 is communicated with the communication channel 414. The blower 42 can send air into the inner tank assembly 1 through the air supply channel 413, the communication channel 414, and the inner tank air inlet 102.

[0152] In some embodiments, the inner tank assembly 1 may have an inner tank air inlet 102 and an inner tank air outlet. The inner tank air inlet 102 is in a shape extending upwardly. The main body portion 41 has an insertion tube 4117 with an opening downward and communicating with the inner space of the inner tank assembly 1. The insertion tube 4117 is inserted into the inner tank air inlet 102. Thus, it is convenient to connect and communicate the blower anti-siphon assembly 4 with the inner tank assembly 1, simplifies the connection structure, and improves the assembly and disassembly efficiency.

[0153] In some embodiments, the blower anti-siphon assembly 4 is installed on the outer side surface of the inner tank assembly 1. Thus, it can avoid the blower anti-siphon assembly 4 occupying the internal space of the inner tank assembly 1. At the same time, the distance between the inner tank assembly 1 and the blower anti-siphon assembly 4 is shortened, which is convenient for the direct connection between the inner tank assembly 1 and the blower anti-siphon assembly 4.

[0154] In some embodiments of the present invention, the water tank 2 and the blower anti-siphon assembly 4 are arranged on adjacent sides of the inner tank assembly 1. Combining Figure 2 , the water tank 2 is arranged at the rear side of the inner tank assembly 1, and the blower anti-siphon assembly 4 is arranged at the right side of the inner tank assembly 1. Thus, the overall structure of the dishwasher 100 can be made more compact and reasonable.

[0155] In some embodiments, the dishwasher 100 may further include: a heating assembly 9. The heating assembly 9 has a heating chamber. The inner tank assembly 1, the heating chamber, the washing pump 7, and the spray arm assembly 8 are connected in series. When the dishwasher 100 operates, during the process of the water in the inner tank assembly 1 being pumped by the washing pump 7, the water will first flow through the heating chamber of the heating assembly 9, be heated by the heating chamber, then enter the washing pump 7, be pumped by the washing pump 7 to the spray arm assembly 8 to spray the tableware, and then the water drops back to the bottom of the inner tank assembly 1, and then circulates through the heating chamber, the washing pump 7, and the spray arm assembly 8 to clean the tableware. That is to say, the water will be heated cyclically by the heating assembly 9 during the washing process, so that the water in the inner tank assembly 1 is slowly heated as a whole, and hot water is used for washing, thereby improving the cleaning effect on the tableware.

[0156] In some embodiments, the inner container assembly 1 may include: an inner container 11 and a water cup 12.

[0170] The steam generator 5 is connected in series between the water tank water outlet chamber 202 and the water cup 12 of the inner tank assembly 1 for supplying water or steam into the inner tank assembly 1.

[0171] The following details the water circuit connection of the above dishwasher 100:

[0172] When automatic water inlet is adopted: The water tap is connected to the water inlet valve. The water inlet valve is connected to the first water softener water inlet 301. The second water softener water inlet 302 is connected to the water tank water outlet 206 at the bottom of the water adding chamber 201. The water softener water outlet 303 is connected to the water tank soft water inlet 207. The water tank drain valve 23 at the bottom of the water tank is connected to the steam generator 5. The steam generator 5 is connected to a base water inlet 101 of the inner tank 11. The water tank regeneration water outlet 208 is connected to the water inlet passage 322 of the regeneration component 32 of the water softener 3. The drain pump 6 is connected to a water flow passage inlet 4121 of a water flow passage 412 of the fan anti-siphon component 4.

[0173] The water flow process is as follows: When the dishwasher 100 fills with water, the water inlet valve opens, and water passes through the first water softener water inlet 301. Part of the water flows through the second water softener water inlet 302 to the water adding chamber 201 of the water tank 2, and part of the water flows through the resin chamber of the water softening assembly 31 to the water outlet chamber 202 of the water tank 2. When the water level detection device 24 reminds that the water has been added enough, the water addition stops and the water inlet valve is closed. At this time, the regeneration chamber 203 of the water tank is also full of water. Then the machine runs, the water discharge valve 23 of the water tank opens, and water is fed in regularly. Because the base water inlet 101 is lower than the water discharge valve 23 of the water tank, there is a water level difference. Water flows from the water tank 2 through the water pipeline of the steam generator 5 to the base water inlet 101 and then flows into the water cup 12 of the inner tank assembly 1. After the set time point, the water discharge valve 23 of the water tank is closed. Since the water outlet chamber 202 and the water adding chamber 201 of the water tank are in communication, when the water level in the water outlet chamber 202 of the water tank drops, the water in the water adding chamber 201 will flow through the resin chamber of the water softener 3 to the water outlet chamber 202 of the water tank 2 until the water levels in the two chambers are equal.

[0174] When adding water manually: The first water softener water inlet 301 is connected to the water outlet of the water inlet valve, the second water softener water inlet 302 is connected to the water outlet 206 of the water tank at the bottom of the water adding chamber 201, the water outlet 303 of the water softener is connected to the water inlet 207 of the water tank soft water in the water outlet chamber 202, the water discharge valve 23 of the water tank is connected to the steam generator 5, the steam generator 5 is connected to the base water inlet 101, the regeneration water outlet 208 of the water tank is connected to the water inlet channel 322 of the regeneration assembly 32 of the water softener 3, and the drainage pump 6 is connected to the water inlet 4121 of the water flow channel 412 of the air blower anti-siphon assembly 4.

[0175] The water flow process is as follows: Before the dishwasher 100 runs, water is added to the water adding port 204 of the water tank 2. Due to the principle of high and low water level difference, water will flow from the water adding chamber 201 of the water tank 2 through the resin chamber of the water softening assembly 31 of the water softener 3 into the water outlet chamber 202 of the water tank 2 until the water levels in the water adding chamber 201 and the water outlet chamber 202 are equal. When the water level detection device 24 reminds that the water has been added enough, the water addition stops. At this time, the regeneration chamber 203 of the water tank 2 is also full of water. Then the dishwasher 100 runs, the water discharge valve 23 of the water tank opens, and water is fed in regularly. Because the base water inlet 101 is lower than the water discharge valve 23 of the water tank, there is a water level difference. Water flows from the water tank 2 through the water pipeline of the steam generator 5 to the base water inlet 101 and then flows into the inner tank assembly 1. After the set time point, the water discharge valve 23 of the water tank is closed (that is to say, the base water inlet is provided at the bottom of the inner tank assembly, the water discharge valve of the water tank is respectively connected to the bottom of the water tank and the base water inlet of the inner tank assembly, and the base water inlet is lower than the water discharge valve of the water tank).

[0176] Washing process of the dishwasher 100: When the dishwasher 100 is washing dishes, the water in the water cup 12 of the inner tank assembly 1 is pumped in by the washing pump 7 and then thrown out. The water is sprayed onto the tableware in the inner tank 11 through the upper and lower spray arm assembly 8 (i.e., washing). After the water droplets fall, they flow towards the lowest point, the water cup 12, and then are pumped away by the washing pump 7, realizing the circulating washing process of the water. When the water in the water cup 12 in the inner tank 11 is pumped by the washing pump 7, it will pass through the heating chamber of the heating assembly 9 and be heated. Therefore, the water will be heated in a cycle during the washing process, and the water in the inner tank 11 will be heated slowly as a whole.

[0177] Drainage of the dishwasher 100: After the washing is completed, the drain pump 6 is turned on to drain the water in the water cup 12. The drained water enters the water flow channel 412 of the fan anti-siphon assembly 4 from the outlet of the drain pump 6 and is discharged through the water flow channel outlet 4122 of the water flow channel 412 and flows into the sewer. Steam disinfection of the dishwasher 100: After the dishwashing and rinsing are completed, the steam generator 5 is turned on. The steam generator 5 adds water, causing the water in the cavity of the steam generator 5 to quickly evaporate into high-temperature gas. The gas expands, squeezing out the water in the water pipe between the steam generator 5 and the base water inlet 101. Then the steam enters the inner tank 11 and is sprayed onto the tableware to achieve the effect of high-temperature disinfection. Regeneration of the soft water component 31 of the dishwasher 100 (i.e., reduction of the resin in the resin cavity of the soft water component 31 of the water softener 3): After the rinsing of the dishwasher 100 is completed, if the regeneration program is set, the switching valve 323 of the regeneration component 32 of the water softener 3 is opened. The water in the regeneration cavity 203 of the water tank 2 flows towards the salt cavity 321 of the lower-positioned water softener 3 under the action of gravity. The water squeezes up from the bottom of the salt cavity 321, fully mixing with the salt to form saturated brine, and then enters the resin cavity of the soft water component 31 from the top of the salt cavity 321 to start reducing the resin. The original water in the resin of the water softener 3 and the salt cavity 321 is squeezed into the water outlet cavity 202 of the water tank 2. The water tank drain valve 23 and the drain pump 6 are turned on to drain these waste waters.
