Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to dishwasher water system and dishwasher. Background Technology

[0002] With the continuous development of dishwashers, their functions have been constantly optimized and improved, from the initial focus on water and energy saving to today's unique washing methods. Common dishwashers typically use a split water system to divide the entire dishwasher into independent single-layer washing sections, thus achieving less water and less energy consumption. At the same time, many special functions have been added for drying dishes, such as fan drying and automatic door opening. However, these only dry the dishes inside the dishwasher; they do not dry the overall water system, leaving it in a damp environment prone to mold and bacterial growth. Utility Model Content

[0003] In view of this, the present invention provides a dishwasher water system and a dishwasher to solve the problem that the existing dishwasher water system is prone to mold and bacteria growth in a humid environment.

[0004] In a first aspect, this utility model provides a dishwasher water system, comprising:

[0005] The water distribution device includes a housing with a water distribution chamber, and the housing is provided with an inlet, an outlet and an air inlet respectively communicating with the water distribution chamber;

[0006] A spray device is connected to a water outlet and is suitable for spraying water or blowing air into the interior of the dishwasher.

[0007] A ventilation and drying device, with its air outlet and air inlet connected, is suitable for blowing air into the water distribution chamber.

[0008] Beneficial effects: By adding a ventilation and drying device to the traditional water distribution device, the internal water circuit of the dishwasher can be ventilated and dried through the water distribution device, thus ensuring the overall drying effect of the water circuit. This reduces the impact of moisture and mold on the internal water circuit and effectively solves the problem of existing dishwasher water circuit systems being in a humid environment for a long time, which easily leads to mold and bacteria growth. In addition, the air introduced into the water distribution chamber by the ventilation and drying device is sprayed into the inner cavity of the dishwasher through the spray device, which not only dries the dishwasher water circuit system quickly, but also accelerates the drying of the tableware. At the same time, the airflow blown out by the spray nozzles of the spray device is more evenly dispersed, which can achieve the effect of rapid air drying of the entire tableware. The drying effect is better and more efficient, and it can simultaneously improve the drying performance of the dishwasher water circuit system, thereby greatly improving the drying performance and practicality of the dishwasher and enhancing the user experience.

[0009] In one optional embodiment, the ventilation and drying device includes:

[0010] Wind turbine components;

[0011] The air inlet duct connects the air outlet and air inlet of the fan assembly.

[0012] Beneficial effects: When you want to dry the water system or dishes, the fan unit is activated. The fan sends fresh air into the water distribution chamber of the water distribution device through the air inlet pipe. This dries the dishes in the dishwasher at the same time as the internal water system formed by the water distribution device and the spray device. This reduces the impact of moisture and mold on the internal water system and greatly improves the practicality of the dishwasher.

[0013] In one optional embodiment, the water separation device further includes:

[0014] The water separator is rotatably installed in the water separator chamber. The water separator is provided with a water separator inlet, a water separator outlet and a water separator air inlet.

[0015] The dishwasher has a wash mode and a dry mode:

[0016] When the dishwasher is in the washing mode, the water divider rotates to the water inlet position where the water inlet of the water divider is connected to the water outlet, the water outlet of the water divider is connected to the water outlet, and the air inlet of the water divider is blocked from the air outlet.

[0017] When the dishwasher is in dry mode, the water divider rotates to the air intake position where the water divider air inlet is connected to the air inlet and the water divider water outlet is connected to the water outlet.

[0018] Beneficial effects: During the washing stage, the water separator is rotated to a position where its inlet connects with the inlet of the casing. Water is then diverted to the spray system through the outlet on the separator. During this process, the air inlet of the separator is sealed to the inner wall of the casing, creating a non-interconnected space and preventing the high-pressure water from flowing out. During the drying stage, the water separator is rotated to connect its air inlet with the air inlet of the casing. Simultaneously, the fan assembly of the ventilation and drying device is activated, sending fresh air into the water separator chamber through the air intake pipe. This fresh air then flows through the inlet and outlet of the separator to the spray system, and finally, is dispersed through the spray nozzles of the spray system onto the dishes. This process dries both the dishes and the internal water system simultaneously, reducing the risk of mold and mildew in the internal water system and greatly improving the dishwasher's practicality.

[0019] In one optional embodiment, the water inlet and the air inlet are circumferentially spaced on the peripheral wall of the water distribution chamber, and the water outlet is located on the top wall of the water distribution chamber.

[0020] The water separator includes a top wall and a peripheral wall connected to the outer periphery of the top wall. The water inlet and air inlet of the water separator are circumferentially spaced on the peripheral wall of the water separator, and the water outlet of the water separator is located on the top wall of the water separator.

[0021] Beneficial effects: The water inlet and air inlet, as well as the water inlet and air inlet of the water divider, are respectively arranged circumferentially on the peripheral walls of the water dividing chamber and the water divider. This facilitates the connection or blockage between the water inlet and the water divider inlet, and between the air inlet and the water divider air inlet, by controlling the rotation of the water divider. By setting the water outlet and the water divider outlet on the top wall of the water dividing chamber and the water divider respectively, it is convenient to achieve the water flow between the water outlets of the water divider and the water outlet, as well as between the water outlet and the spray device.

[0022] In one optional embodiment, the water separation device further includes:

[0023] A sealing element is installed on the outer periphery of the water separator to seal the gap between the outer peripheral wall of the water separator and the inner peripheral wall of the water separator cavity.

[0024] Beneficial effects: During the washing stage, the air inlet of the water separator is circumferentially offset from the air inlet on the housing, and the water inlet of the water separator corresponds to the water inlet on the housing. Through the installation of a sealing element, the air inlet of the water separator is tightly fitted to the inner wall of the water separator chamber, forming a non-communicating space. The peripheral wall of the water separator is sealed against the air inlet, blocking the air inlet and preventing high-pressure water from flowing out. This prevents water in the water separator chamber from flowing into the fan assembly through the air inlet of the water separator and the air inlet on the housing, thus preventing damage to the fan. During the drying stage, the air inlet of the water separator corresponds to the air inlet on the housing, and the water inlet of the water separator is circumferentially offset from the water inlet on the housing. Through the installation of a sealing element, the water inlet of the water separator is tightly fitted to the inner wall of the water separator chamber, forming a non-communicating space, preventing the incoming drying air from flowing into the dishwasher's water inlet mechanism.

[0025] In one optional embodiment, the water separation device further includes:

[0026] The drive mechanism is installed outside the housing. The output end of the drive mechanism is connected to the water divider and is suitable for driving the water divider to rotate between the water inlet position and the water inlet position.

[0027] Beneficial effects: The designed drive mechanism allows the water separator to rotate between the water inlet and air inlet positions, making it easier for the dishwasher to switch between washing and drying modes, resulting in higher controllability and intelligence.

[0028] In one alternative embodiment, the housing includes:

[0029] A water cup with a water-dividing chamber that opens at the top;

[0030] The water distribution cover is fixedly installed at the open end and forms a closed water distribution chamber with the water cup. The water outlet is located on the water distribution cover.

[0031] Beneficial effects: The shell design, with its water cup and water distribution cover, facilitates the maintenance and cleaning of the internal structure of the water distribution chamber, makes it easy to connect with the spraying device, and also makes demolding easier.

[0032] In one optional embodiment, the water outlet includes a first water outlet and a second water outlet that are circumferentially spaced along the water distribution cover.

[0033] The spraying device includes an upper spraying assembly and a lower spraying assembly. The water inlet of the upper spraying assembly is connected to the first water outlet, and the water inlet of the lower spraying assembly is connected to the second water outlet.

[0034] Beneficial effects: By using upper and lower spray components, the spray device can allow water or air to enter the dishwasher cavity from both the top and bottom, improving the washing and drying effects.

[0035] In one alternative implementation, the upper spray assembly includes:

[0036] The sprinkler pipe has its inlet connected to the first outlet.

[0037] The top spray arm and the middle spray arm are arranged at intervals, and are connected to the spray water pipes respectively.

[0038] Beneficial effects: The upper spray assembly, with its top and middle spray arms, can work in conjunction with the lower spray assembly to achieve water or air spraying from the top, middle, and bottom, further improving the washing and drying effects of the dishes in the dishwasher cavity.

[0039] In one optional embodiment, the water outlet of the water divider includes a third outlet and a fourth outlet that are spaced apart circumferentially along the water divider.

[0040] When the dishwasher is in washing mode, the first and third water outlets are connected, and the second and fourth water outlets are connected; when the dishwasher is in drying mode, the first and fourth water outlets are connected, and the second and third water outlets are connected.

[0041] Beneficial effects: By setting the third and fourth water outlets on the water separator, it is convenient to connect the water outlet of the water separator and the water outlet on the shell when the water separator is in the water inlet and air inlet positions.

[0042] Secondly, this utility model also provides a dishwasher, including the dishwasher water system of any of the above embodiments. Attached Figure Description

[0066] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0067] The following is combined with Figures 1 to 11 The following describes embodiments of the present invention.

[0068] According to embodiments of the present invention, on the one hand, in conjunction with Figure 1 and Figure 2 As shown, this utility model provides a dishwasher water system, including: a water distribution device 10, a spray device 30, and a ventilation and drying device 20. The water distribution device 10 includes a housing 11 with a water distribution chamber 1110. The housing 11 is provided with a water inlet 1111, a water outlet 1121, and an air inlet 1112 that are respectively connected to the water distribution chamber 1110. The spray device 30 is connected to the water outlet 1121 and is suitable for spraying water or blowing air into the inner cavity of the dishwasher. The air outlet of the ventilation and drying device 20 is connected to the air inlet 1112 and is suitable for blowing air into the water distribution chamber 1110.

[0069] In the above embodiment, by adding a ventilation and drying device 20 to the traditional water distribution device 10, the water distribution device 10 can ventilate and dry the internal water circuit of the dishwasher, thereby ensuring the overall drying effect of the water circuit, reducing the impact of dampness and mold on the internal water circuit, and effectively solving the problem that the existing dishwasher water circuit system is in a humid environment for a long time, which is prone to mold and bacteria growth. In addition, the air introduced into the water distribution chamber 1110 by the ventilation and drying device 20 is sprayed into the inner cavity of the dishwasher through the spray device 30, which can quickly dry the water circuit system of the dishwasher and accelerate the drying of the tableware. At the same time, the airflow blown out by the spray holes of the spray device 30 is more evenly dispersed, which can achieve the effect of rapid air drying of the entire tableware. The drying effect is better and the efficiency is higher, and the drying performance of the dishwasher water circuit system can be improved at the same time, thereby greatly improving the drying performance and practicality of the dishwasher and improving the user experience.

[0070] Specifically, the water inlet 1111, water outlet 1121, and air inlet 1112 are all interface structures formed on the outer wall of the housing 11, facilitating connection with external pipelines. The water inlet 1111 is connected to the water inlet mechanism of the dishwasher, which includes a water pump and a water inlet pipe. The water inlet pipe is connected between the water pump and the water inlet 1111. The water inlet mechanism can deliver water to the spray device 30 through the water distribution device 10. The air outlet of the ventilation and drying device 20 is connected to the air inlet 1112 of the water distribution device 10, which can blow air into the water distribution chamber 1110. Since the spray device 30 is connected to the water outlet 1121 of the water distribution device 10, the air entering the water distribution chamber 1110 can also flow into the spray device 30 and be sprayed into the inner cavity of the dishwasher. This achieves both ventilation and drying of the water system inside the water distribution device 10 and the spray device 30, and drying of the dishes inside the dishwasher.

[0071] Furthermore, in this embodiment, the dishwasher has a drying mode and a washing mode. In one optional implementation, when the dishwasher is in the drying mode, the water passage between the water inlet mechanism and the water distribution device 10 is closed, that is, the water inlet 1111 is closed, thereby preventing the air entering the water distribution chamber 1110 from flowing into the water inlet mechanism through the water inlet 1111, causing excessive water pressure and potentially leading to related safety hazards. In another optional implementation, combined with... Figure 11 As shown, when the dishwasher is in drying mode, the water passage between the water inlet mechanism and the water distribution device 10 is partially open, allowing a small amount of drying gas to enter the water inlet pipe without causing excessive water pressure, while still achieving a good drying effect. When the dishwasher is in washing mode, the air passage between the ventilation drying device 20 and the water distribution device 10 is closed, that is, the air inlet 1112 is closed, thereby preventing water in the water distribution chamber 1110 from flowing into the ventilation drying device 20 through the air inlet 1112 and damaging the ventilation drying device 20.

[0072] In some embodiments, the water passage between the water inlet mechanism and the water distribution device 10, or the air passage between the ventilation and drying device 20 and the water distribution device 10, can be opened or closed by a sealing structure provided within the water distribution device 10 in conjunction with a rotating water distribution plate 12. Alternatively, in other alternative embodiments, the water passage between the water inlet mechanism and the water distribution device 10, or the air passage between the ventilation and drying device 20 and the water distribution device 10, can be opened or closed by providing a switching valve at the water inlet 1111 or the air inlet 1112.

[0073] In some embodiments, the ventilation and drying device 20 includes a fan assembly 21 and an air inlet duct 22, the air inlet duct 22 being connected between the air outlet and the air inlet 1112 of the fan assembly 21.

[0074] In the above embodiment, when it is desired to dry the water system or tableware, the fan assembly 21 is activated. The fan sends fresh air into the water distribution chamber 1110 of the water distribution device 10 through the air inlet pipe 22, thereby achieving the simultaneous drying of the dishwasher tableware and the internal water system of the dishwasher formed by the water distribution device 10 and the spray device 30. This reduces the impact of moisture and mold on the internal water system and greatly improves the practicality of the dishwasher.

[0075] Specifically, the fan assembly 21 is located outside the housing 11. The fan assembly 21 includes a volute and a fan disposed inside the volute. The volute is provided with an air inlet and an air outlet. The air inlet communicates with the external space of the dishwasher. The air inlet pipe 22 is connected between the air outlet of the volute and the air inlet 1112 of the housing 11.

[0076] In some embodiments, combined with Figure 1 , Figure 2 and Figures 4 to 6 , Figure 8 and Figure 9 As shown, the water distribution device 10 also includes a water distribution plate 12, which is rotatably disposed within the water distribution chamber 1110. The water distribution plate 12 is provided with a water inlet 121, a water outlet 122, and an air inlet 123. The dishwasher has a washing mode and a drying mode: combined Figure 9 , Figure 10 As shown, when the dishwasher is in washing mode, the water separator 12 rotates to a position where the water inlet 121 connects with the water inlet 1111, the water outlet 122 connects with the water outlet 1121, and the air inlet 123 is blocked from the air inlet 1112. Combined with... Figure 8 , Figure 11 As shown, when the dishwasher is in drying mode, the water divider 12 rotates to the air intake position where the water divider air inlet 123 is connected to the air inlet 1112 and the water divider water outlet 122 is connected to the water outlet 1121.

[0077] In the above embodiment, during the washing stage, the water divider 12 is controlled to rotate to the water inlet position where the water inlet 121 of the water divider is connected to the water inlet 1111 of the housing 11. Then, the water is diverted to the spray device 30 through the water outlet 1121 provided on the water divider 12. During this process, the air inlet 123 of the water divider is sealed with the inner wall of the housing 11 to form a non-connected space. The air inlet 1112 of the housing 11 is closed, preventing the internal high-pressure water from flowing out. During the drying stage, by controlling the rotation of the water divider 12, the air inlet 123 of the water divider is connected to the air inlet 1112 of the housing 11. At the same time, the fan assembly 21 of the ventilation and drying device 20 is started, and fresh air is sent into the water divider chamber 1110 through the air inlet pipe. The air then flows to the spray device 30 through the water inlet 121 and outlet 1121 of the water divider, and finally dispersed and blown to each dish through the spray holes of the spray device 30. This not only dries the dishwasher dishes but also dries the built-in water circuit at the same time, reducing the impact of moisture and mold on the built-in water circuit and greatly improving the practicality of the dishwasher.

[0078] It should be noted that when the dishwasher is in the drying mode, the water inlet 121 and the water inlet 1111 of the water divider can be in a blocked state to prevent air intake from causing excessive water pressure inside the water inlet mechanism, or the water inlet 121 and the water inlet 1111 can be in a connected state to allow an appropriate amount of drying gas to be introduced into the water inlet pipe to achieve the purpose of drying the water inlet pipe. In this embodiment, there is no specific limitation on whether the water inlet 121 and the water inlet 1111 of the water divider are in a closed state during the drying mode.

[0079] In some embodiments, combined with Figure 5 and Figure 6 As shown, the water inlet 1111 and the air inlet 1112 are circumferentially spaced on the peripheral wall of the water distribution cavity 1110, and the water outlet 1121 is located on the top wall of the water distribution cavity 1110; the water distribution plate 12 includes a top wall and a peripheral wall connected to the outer periphery of the top wall, the water inlet 121 and the air inlet 123 of the water distribution plate are circumferentially spaced on the peripheral wall of the water distribution plate 12, and the water outlet 122 of the water distribution plate is located on the top wall of the water distribution plate 12.

[0080] In the above embodiments, the water inlet 1111 and the air inlet 1112, as well as the water inlet 121 and the air inlet 123 of the water divider are respectively arranged circumferentially on the peripheral walls of the water dividing cavity 1110 and the water divider 12. This facilitates the connection or blockage between the water inlet 1111 and the water inlet 121, and between the air inlet 1112 and the air inlet 123 of the water divider by controlling the rotation of the water divider 12. By correspondingly arranging the water outlet 1121 and the water outlet 122 of the water divider on the top walls of the water dividing cavity 1110 and the water divider 12, it is convenient to realize the water path connection between the water outlet 122 and the water outlet 1121, and between the water outlet 1121 and the spray device 30.

[0081] Specifically, the water separator 12 includes a circular top wall and a cylindrical peripheral wall disposed below the top wall. The water separator inlet 121 and the water separator air inlet 123 are disposed circumferentially on the cylindrical peripheral wall of the water separator 12. Optionally, the water separator air inlet 123 is a circular hole, and the water separator inlet 121 is a strip hole disposed on the peripheral wall.

[0082] In some embodiments, combined with Figures 5 to 8 As shown, the water distribution device 10 also includes a sealing element 13, which is disposed on the outer periphery of the water distribution plate 12 and is used to seal the fitting gap between the outer peripheral wall of the water distribution plate 12 and the inner peripheral wall of the water distribution cavity 1110.

[0083] In the above embodiments, such as Figure 9 As shown, in the washing mode, the air inlet 123 of the water separator is offset from the air inlet 1112 on the housing 11 in the circumferential direction, and the water inlet 121 of the water separator corresponds to the water inlet 1111 on the housing 11. Through the provided sealing element 13, the air inlet 123 of the water separator and the inner wall of the water separator cavity 1110 are tightly fitted to form a non-communicating space. The peripheral wall of the water separator 12 is sealed and attached to the air inlet 1112 by the sealing element 13, sealing the air inlet 1112 and preventing the internal high-pressure water from flowing out, thus preventing water in the water separator cavity 1110 from flowing from the air inlet 123 of the water separator and the air inlet 1112 on the housing 11 into the fan assembly 21 and damaging the fan. During the drying stage, the air inlet 123 of the water divider corresponds to the air inlet 1112 on the housing 11, and the water inlet 121 of the water divider is offset from the water inlet 1111 on the housing 11 in the circumferential direction. Through the provided sealing member 13, the water inlet 121 of the water divider is tightly fitted with the inner wall of the water dividing cavity 1110 to form a non-communicating space, so as to prevent the incoming drying air from flowing into the water inlet mechanism of the dishwasher.

[0084] Specifically, in combination Figure 5 and Figure 6 As shown, a sealing groove 120 is provided on the outer periphery of the water separator 12, and a sealing element 13 is embedded in the sealing groove 120. Preferably, the sealing element 13 is a sealing ring. The upper and lower ends of the water separator 12 are thickened to form two annular protrusions. Multiple reinforcing ribs are provided between the two annular protrusions. The multiple reinforcing ribs are arranged at intervals along the circumference of the water separator 12 on the outer peripheral wall of the water separator 12. The sealing groove 120 is formed on the annular protrusions and the reinforcing ribs to ensure structural strength. A thin-walled area is formed between two adjacent reinforcing ribs. The water inlet 121 and the air outlet of the water separator 12 are located in different thin-walled areas. Preferably, there are four reinforcing ribs, and the water inlet 121 and the air outlet of the water separator 12 are located in two opposite thin-walled areas.

[0085] Furthermore, the sealing groove 120 is formed on the outer wall of the annular protrusion and the reinforcing rib, and the sealing element 13 includes two sealing rings arranged at intervals, and a plurality of sealing ribs connected between the two sealing rings. The number and position of the plurality of sealing ribs correspond to the number and position of the plurality of reinforcing ribs.

[0086] In some embodiments, the water distribution device 10 further includes a drive mechanism 14, which is installed outside the housing 11. The output end of the drive mechanism 14 is connected to the water distribution plate 12 and is adapted to drive the water distribution plate 12 to rotate between the water inlet position and the water inlet position.

[0087] In the above embodiment, the drive mechanism 14 facilitates the rotation of the water separator 12 between the water inlet position and the air inlet position, thereby facilitating the switching of the dishwasher between the washing mode and the drying mode, resulting in higher controllability and intelligence.

[0088] Specifically, in combination Figure 2 , Figure 4 and Figure 6 As shown, the drive mechanism 14 includes a water-distributing motor 141 and a water-distributing rotating shaft 142. The water-distributing motor 141 is installed on the outer side of the bottom wall of the housing 11. One end of the water-distributing rotating shaft 142 is connected to the water-distributing motor 141, and the other end extends into the water-distributing cavity 1110 and is connected to the water-distributing plate 12.

[0089] Furthermore, a motor mounting hole 1113 is provided on the bottom wall of the housing 11, allowing the water-distributing shaft 142 to extend into the water-distributing cavity 1110 and connect with the water-distributing plate 12. A shaft connecting part 124 is provided in the middle of the top wall of the water-distributing plate 12. A keyway is provided within the shaft connecting part 124, and a key is provided at the end of the water-distributing shaft 142. The upper end of the water-distributing shaft 142 is inserted into the shaft connecting part 124, and the keyway and key cooperate to achieve a circumferential connection between the two, thus facilitating the water-distributing motor 141 to drive the water-distributing shaft 142 to drive the water-distributing plate 12 to move circumferentially. The cooperation of the key and keyway not only enables synchronous rotation of the water-distributing shaft 142 and the water-distributing plate 12 in the circumferential direction but also facilitates disassembly and assembly.

[0100] Preferably, in this embodiment, the first and third water outlets are both oblong holes, and the second and fourth water outlets are both circular holes.

[0101] Secondly, this utility model also provides a dishwasher, including the dishwasher water system of any of the above embodiments.

[0102] This application provides an application of a built-in drying system for a dishwasher, which adds a ventilation and drying device 20 to the traditional water distribution device 10, thereby achieving a drying effect for the entire water circuit. This can effectively improve the drying performance of dishwasher dishes and simultaneously improve the drying performance of the dishwasher's water circuit system.

[0103] The specific structure and working principle of the dishwasher water system provided in this embodiment are as follows:

[0104] The specific structure is as follows: The dishwasher water system includes a water cup 111, a water distribution motor 141, a water distribution shaft 142, a water distribution plate 12, a seal 13, a water distribution cover plate 112, a fan assembly 21, an air inlet pipe, and a spray device 30. The water distribution plate 12 is installed and fixed inside the water distribution chamber 1110 of the water cup 111. The water distribution motor 141 drives the water distribution shaft 142 to drive the water distribution plate 12 to move in a circumferential direction. The water distribution cover plate 112 is installed and fixed at the top opening of the water distribution chamber 1110 of the water cup 111, and is connected to the third and fourth water outlets on the water distribution plate 12. The spray device 30 includes a spray water pipe 311 connected to the water distribution cover plate 112, a lower spray assembly 32, a top spray arm 312 connected to the spray water pipe 311, and a middle spray arm 313, thus forming the entire water system of the dishwasher.

[0105] The working principle is as follows: During the washing stage, water enters through the water inlet 121 of the water divider plate and the water inlet 1111 of the housing 11. Under the operation of the water divider motor 141, the water divider plate 12 moves in a circumferential direction. The water is divided into the water divider cover plate 112 through the third and fourth water outlets on the water divider plate 12, and then flows further down to the spray assembly 32 or the spray pipe 311, until it reaches the top spray arm 312 and the middle spray arm 313. During this process, the air inlet 123 of the water divider plate 12 is tightly fitted with the inner wall of the water cup 111 through the sealing element 13 to form a non-communicating space. At the same time, the air inlet 1112 of the water cup 111 and the water divider cover plate 112 are also sealed by the sealing element 13 to prevent the internal high-pressure water from flowing out. During the drying stage, the synchronous motor drives the water separator 12 to rotate, connecting the air inlet 123 of the water separator to the air inlet 1112 of the water cup 111. Simultaneously, the fan assembly 21 is activated, sending fresh air into the water separator chamber 1110 of the water cup 111 through the air intake pipe. The air then flows through the water inlet 121 into the washing pipe, while on the other side, it flows through the water outlet 122 to the spray pipe 311 and the lower spray assembly 32 connected to the water separator cover 112. The air then flows further to the top spray arm 312 and the middle spray arm 313, and finally disperses through the spray holes on the spray arms to the various dishes. This achieves simultaneous drying of the dishwasher dishes and the internal water system, reducing the risk of mold and mildew in the internal water system and greatly improving the dishwasher's practicality.

[0106] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
