Detailed Implementation

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1 to 6 According to an embodiment of the present invention, a dishwasher 100 includes: a main body 10, a reversing device 20, and an air inlet device 30. The main body 10 is used for storing and washing tableware, the air inlet device 30 is used for supplying air into the main body 10, and the reversing device 20 is used for switching the air inlet direction of the air inlet device 30.

[0033] Specifically, the main body 10 of the device includes a water cup 11, a drain assembly 12, and a washing assembly 13. The water cup 11 is used to collect and store water. For example, at the start of washing, washing water is introduced into the water cup 11 so that the washing pump 131 can draw water from the water cup 11 for the dishwasher 100 to clean the dishes. During washing, the washing water falls into the water cup 11 after cleaning the dishes in the washing chamber. After washing is completed, or when drainage is needed during washing, the washing water is stored in the water cup 11 and can be drained from the water cup 11 using the drain outlet. The drain assembly 12 is connected to the water cup 11, allowing the water in the water cup 11 to be drained under the action of the drain assembly 12. The drain assembly 12 can be configured as a suction drain; specifically, water can be drawn from the drain outlet using the drain assembly 12 and then discharged from the water cup 11. The washing assembly 13 is used to clean the tableware and other items stored in the washing chamber. The washing assembly 13 can be connected to the water cup 11. When it is necessary to clean the tableware, the washing assembly 13 can send the water in the water cup 11 to the washing chamber and clean the tableware and other items in the washing chamber by rinsing or other means.

[0034] The reversing device 20 has an air inlet 208 and an air outlet. The reversing device 20 controls the connection and disconnection of the air inlet 208 and the air outlet. The air outlet is connected to at least one of the water cup 11, the drain assembly 12, and the washing assembly 13. The air inlet device 30 is connected to the air inlet 208. The air inlet device 30 can supply air to the air inlet 208. The reversing device 20 can control the airflow, thereby switching the airflow direction and controlling the on / off state of the airflow, so as to achieve airflow control.

[0035] According to the present invention, the dishwasher 100 can adjust the air supply direction of the air inlet device 30 by using the reversing device 20, thereby achieving air drying of different parts of the dishwasher 100. This can reduce the possibility of bacterial growth inside the dishwasher 100 leading to odors, thus ensuring the washing effect of the dishwasher 100. In addition, when it is necessary to use the dishwasher 100 to store tableware, etc., the air blowing can be used to dry different parts inside the dishwasher 100, which can improve the storage effect of tableware and extend the storage time of tableware.

[0036] The air inlet device 30 in this invention can both remove residual water and dry the surface. Removing residual water involves pressurizing the cavity within the main body 10 using the air inlet device to expel water from the cavity. Drying involves using airflow to carry away water adhering to the cavity walls, thus drying the cavity walls. For the drainage component 12, due to its piping arrangement, some water may remain. Therefore, by pressurizing the flow path of the drainage component 12, the water is expelled. After the water is expelled, some water remains adhering to the pipe walls. At this point, the drying capability of the air inlet device 30 allows airflow passing through the drainage component to carry away the water adhering to the pipe walls, thereby drying the drainage component. Furthermore, the air inlet device 30 can also remove and dry residual water from the washing pump and the inner wall of the pump cavity, as well as from the spray assembly, tableware, and water cups.

[0037] The air inlet 208 in this invention may include one or more inlets, including but not limited to the following examples.

[0038] Example 1: The air outlet includes a first outlet 201, which is connected to the drainage assembly 12. When the reversing device 20 controls the air inlet 208 to connect with the first outlet 201, the airflow from the air inlet device 30 will be delivered to the first outlet 201 and then to the drainage assembly 12. If there is water in the drainage assembly 12, the water can be discharged from the drainage assembly 12 under the action of air pressure. If there is no water in the drainage assembly 12, but there is residual water on the inner wall surface of the drainage assembly 12, the airflow can dry the residual water on the inner wall surface, thereby achieving complete drying of the drainage assembly 12. The drainage assembly 12 of this utility model may include a drainage pump and a drainage pipe. The inlet of the drainage pump can be connected to the drain outlet, and the outlet of the drainage pump can be connected to the drainage pipe. Under the driving action of the drainage pump, the water inlet of the drainage pump can be directed to the outlet and discharged from the outlet into the drainage pipe, and then discharged from the water cup 11 assembly through the drainage pipe. The drain pump may include a pump chamber and a drive unit. The inlet and outlet of the drain pump are conveniently located on the wall of the pump chamber, and the drive unit may include an impeller located in the drain chamber. The wall of the drain chamber may be integrally formed with the water cup 11, for example, the wall of the drain chamber is integrally formed with the water cup 11, and the wall of the drain chamber is arranged around the drain outlet.

[0039] The reversing device 20 can open and close the first outlet 201. When the reversing device 20 opens the first outlet 201, the air inlet 208 is connected to the first outlet 201. When the reversing device 20 closes the first outlet 201, the air inlet 208 is disconnected from the first outlet 201.

[0040] Example 2: The air outlet includes a second outlet 202, which is connected to the water cup 11. When the reversing device 20 controls the air inlet 208 to connect with the second outlet 202, the airflow from the air inlet device 30 will be delivered to the second outlet 202 and then to the water cup 11. The air pressure will drive the water out of the cup. The airflow can also blow onto the inner wall of the water cup 11, drying the inner wall and flat filter screen. Furthermore, the airflow can also blow onto the cylindrical filter screen and cup handle within the water cup 11, drying them as well. Additionally, the airflow can be configured to drive the cylindrical filter screen to rotate, facilitating the removal of residue from the filter screen and improving the washing effect of the dishwasher 100.

[0041] The reversing device 20 can open and close the second outlet 202. When the reversing device 20 opens the second outlet 202, the air inlet 208 is connected to the second outlet 202. When the reversing device 20 closes the second outlet 202, the air inlet 208 is disconnected from the second outlet 202.

[0042] Example 3: The air outlet includes a third outlet 203, which connects to the washing assembly 13. When the reversing device 20 controls the air inlet 208 to connect with the third outlet 203, the airflow from the air inlet device 30 will be delivered to the third outlet 203 and then to the washing assembly 13. The washing assembly 13 may include a washing pump 131, a spray arm, and other structures. When the airflow to the washing assembly 13 passes through the washing pump 131, it can dry the inner cavity of the washing pump 131. An interface can be provided in the pump cavity of the washing pump 131. When there is water in the washing pump 131, the water in the pump cavity can be discharged through the interface under the action of air pressure. In addition, the airflow can also be sent to the spray arm. During the process of the airflow to the spray arm, it can dry the pipeline along the way. When the airflow is delivered to the spray nozzle on the spray arm, it can dry the spray arm and the spray nozzle. In addition, the airflow can also be sprayed out from the spray nozzle to dry the tableware in the washing chamber, etc.

[0043] The reversing device 20 can open and close the third outlet 203. When the reversing device 20 opens the third outlet 203, the air inlet 208 is connected to the third outlet 203. When the reversing device 20 closes the third outlet 203, the air inlet 208 is disconnected from the third outlet 203.

[0044] Of course, the above description is only some embodiments of the present utility model and is not a limitation on the scope of protection of the present utility model. For example, the present utility model may also include a combination of at least two of the above examples one, two and three. In this case, the direction of air intake can be switched by the reversing device 20.

[0045] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0046] like Figure 1 and Figure 3 In some embodiments, the air outlet includes a first outlet 201, a second outlet 202, and a third outlet 203. The first outlet 201 is connected to the drain assembly 12, the second outlet 202 is connected to the water cup 11, and the third outlet 203 is connected to the washing assembly 13. The reversing device 20 can switch the airflow direction. The reversing device 20 can connect the air inlet 208 to at least one of the first outlet 201, the second outlet 202, and the third outlet 203, or it can separate the air inlet 208 from all three outlets. By providing multiple outlets, the airflow direction can be easily controlled, facilitating the drying of different areas of the dishwasher 100 and improving the overall drying effect of the dishwasher 100.

[0047] like Figure 1 and Figure 3In some embodiments, the reversing device 20 has multiple connected states. In the connected state, the reversing device 20 controls at least one of the first outlet 201, the second outlet 202, and the third outlet 203 to open and connect to the air inlet 208. This allows control of the airflow direction to optimize the air-blowing drying effect on the dishwasher 100, thereby improving the drying efficiency and effectiveness of the dishwasher 100.

[0048] The reversing device 20 in this invention can have multiple connection states. For example, it can include controlling the air inlet 208 to connect to the first outlet 201; controlling the air inlet 208 to connect to the second outlet 202; controlling the air inlet 208 to connect to the third outlet 203; controlling the air inlet 208 to connect to the first outlet 201 and the second outlet 202; controlling the air inlet 208 to connect to the first outlet 201 and the third outlet 203; controlling the air inlet 208 to connect to the second outlet 202 and the third outlet 203; controlling the air inlet 208 to connect to the first outlet 201, the second outlet 202, and the third outlet 203, etc. Of course, the reversing device 20 in this invention does not necessarily need to have all of these states. In order to simplify the control of the reversing device 20 and simplify its structure, the reversing device 20 in this invention may only include a part of the above-mentioned connection states.

[0049] In some embodiments of this utility model, such as Figure 8 The system includes multiple connection states, including a first connection state in which the first outlet 201 is opened and the second outlet 202 and the third outlet 203 are closed. In the first connection state, the first outlet 201 is open, and the airflow can be delivered to the drainage assembly 12 after passing through the reversing device 20, facilitating the drying of the drainage assembly 12. Since the drainage assembly 12 may contain a large amount of water, the air intake device uses positive pressure airflow to drive and drain the water from the drainage assembly 12. Therefore, by individually introducing air into the drainage assembly 12, the air pressure of the airflow delivered to the drainage assembly 12 can be increased, thereby improving the drainage effect of the drainage assembly 12.

[0050] like Figure 9The multiple connection states also include a second connection state, in which the first outlet 201 and the second outlet 202 are opened and the third outlet 203 is closed. In the second connection state, the first outlet 201 and the second outlet 202 are open, and the airflow can be sent to the drain assembly 12 and the water cup 11 after passing through the reversing device 20, so as to dry the drain assembly 12 and the water cup 11. During the air-blowing drying process of the water cup 11, a portion of the airflow is sent to the drain assembly 12. During the drying process of the water cup 11, the high-humidity airflow inside the water cup 11 can be sent to the drain assembly 12, and the airflow entering the drain assembly 12 blows away the moisture sent into the drain assembly 12, thereby effectively improving the air-blowing drying effect on the water cup 11 and the drain assembly 12.

[0051] like Figure 10 The multiple connection states also include a third connection state, in which the third outlet 203 is opened and the first outlet 201 and the second outlet 202 are closed. In the third connection state, the third outlet 203 is open, and the airflow can be sent to the washing assembly 13 after passing through the reversing device 20, so as to dry the washing assembly 13. During the air-blowing drying process of the washing assembly 13, since the washing assembly 13 has multiple components to be dried, including the washing pump 131 and the spray arm, individually introducing airflow into the washing assembly 13 can improve the drying effect of the washing assembly 13.

[0052] In addition, such as Figure 11 The reversing device 20 also has a shut-off state, in which the air inlet 208 and the first outlet 201 are closed, and the second outlet 202 and the third outlet 203 are connected. At this time, the air inlet 208 is closed, and the airflow delivered by the air inlet device 30 is difficult to enter the reversing device 20. Moreover, the fluid flowing in the reversing device 20 is also difficult to enter the air inlet device 30 from the air inlet 208. However, when the second outlet 202 and the third outlet 203 are connected, the fluid in the water cup 11 can be sent to the washing assembly 13 through the reversing device 20. In this way, when the dishwasher 100 is washing dishes, the washing assembly 13 can use the water in the water cup 11 to clean the dishes, etc., thereby simplifying the control of the reversing device 20 and enabling the dishwasher 100 to operate more stably and conveniently.

[0053] In some embodiments, the reversing device 20 includes a housing 21 and an air distributor 22, with a first outlet 201, a second outlet 202, and a third outlet 203 disposed on the housing 21. The air distributor 22 is rotatably disposed on the housing 21 along its circumference, and is configured to control the opening of at least one of the first outlet 201, the second outlet 202, and the third outlet 203 by rotation. This simplifies the structure of the reversing device 20, improves the stability and safety of its operation, and enables timely and rapid switching of airflow direction.

[0054] Optionally, the shell 21 is further provided with a sealing section 204, and the first outlet 201, the second outlet 202, the third outlet 203 and the sealing section 204 are distributed along the circumference of the shell 21. This allows the airflow direction to be controlled by the air distribution component 22, simplifies the structure of the heat exchange device, and improves the operational stability of the heat exchange device.

[0055] Among them, combined Figures 7 to 11 In some examples, the first outlet 201, the second outlet 202, the third outlet 203, and the closure 204 are sequentially distributed along the circumference of the housing 21. The air distribution element 22 can be configured to simultaneously block two adjacent outlets.

[0056] In conjunction with the foregoing embodiments, the aforementioned first connected state, second connected state, third connected state, and cut-off state can be quickly achieved. In the first connected state, the air distributor 22 can block the second outlet 202 and the third outlet 203, at which time the first outlet 201 is open; in the second state, when the air distributor 22 rotates, it blocks the third outlet 203 and the sealing part 204, at which time the first outlet 201 and the second outlet 202 are open; in the third connected state, the air distributor 22 blocks the first outlet 201 and the second outlet 202, and the third outlet 203 is open; in the cut-off state, the air distributor 22 blocks the first outlet 201 and the sealing part 204, and the second outlet 202 and the third outlet 203 are open.

[0057] It can be seen that the air distribution component 22 blocks adjacent parts each time, so that the air distribution component 22 can be set as a continuous plate structure. Of course, the air distribution component 22 can also be set as multiple discontinuous plate structures, etc.

[0058] In other examples, the first outlet 201, the second outlet 202, the third outlet 203, and the closure 204 are evenly spaced along the circumference of the housing 21. This allows the air distribution component 22 to switch to the next state without rotating 90°.

[0059] like Figure 8 Only Figure 11 In some embodiments, the air distribution component 22 includes a baffle 221, which is movable circumferentially along the housing 21 to close and open the first outlet 201, the second outlet 202, and the third outlet 203. The movement of the baffle 221 can be used to switch the reversing device 20 between different connectivity states, simplifying the structure of the reversing device 20 and enabling rapid switching between different connectivity states.

[0060] The baffle 221 is designed as a sheet that extends continuously along the circumference of the housing 21, thereby improving the structural strength of the baffle 221 and facilitating the switching of the state of the reversing device 20. Of course, the baffle 221 in this invention can also be provided as multiple non-continuous sheets. For example, in some examples, the baffle 221 has a first sheet portion and a second sheet portion distributed along the circumference of the housing 21.

[0061] As described above, the baffle 221 enables the switching of the reversing device 20 between the first connected state, the second connected state, and the third connected state. When the reversing device 20 needs to switch between the connected state and the closed state, it is necessary to block and open the air inlet 208. Therefore, in some embodiments of this utility model, the air distribution component 22 also includes a baffle 222, which is connected to the baffle 221. The baffle 221 is used to open and close the air inlet 208. In the aforementioned first connected state, second connected state, and third connected state, the baffle 221 can be in the state of opening the air inlet 208. The air inlet 208 can be set at a position offset from the rotation center axis of the air distribution component 22, and a corresponding hollow structure can be provided on the baffle 222 to achieve communication between the air inlet 208 and the inner cavity of the housing 21. Moreover, when the baffle 221 moves to block the first outlet 201 and the closing part 204, the baffle 222 is set to close the air inlet 208. The baffle 221 and the baffle 222 can be set perpendicularly.

[0062] In some embodiments of this utility model, the reversing device 20 is connected to the pipeline between the water cup 11 and the washing assembly 13. In conjunction with the foregoing embodiments, the reversing device 20 has multiple connected and disconnected states. In the disconnected state, the reversing device 20 can connect the water cup 11 and the washing assembly 13, thus connecting them. By connecting the reversing device 20 between the water cup 11 and the washing assembly 13, the reversing device 20 can act as a channel between the water cup 11 and the washing assembly 13, meeting the washing requirements. This reduces changes to the structure of the dishwasher 100, thereby maintaining the stability of the dishwasher 100.

[0063] Optionally, the washing assembly 13 includes a washing pump 131, a water distribution valve 132, and a spray assembly 133. The water distribution valve 132 is connected to the outlet of the washing pump 131; the spray assembly 133 is connected to the water distribution valve 132 and is used to spray a medium into the washing chamber. A reversing device 20 is located between the washing pump 131 and the water cup 11. The air outlet includes a second outlet 202 and a third outlet 203. The second outlet 202 is connected to the water cup 11, and the third outlet 203 is connected to the washing pump 131. This fully satisfies the requirement of connecting the water cup 11 to the washing pump 131 during normal washing, and also meets the requirement of drying using the air inlet device 30, simplifying the structure of the dishwasher 100 and optimizing its performance.

[0064] The air intake device 30 includes a fan 31 and an air intake pipe 32. One end of the air intake pipe 32 is connected to the fan 31, and the other end is connected to the reversing device 20. The fan 31 is an axial flow fan.

[0065] Some specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0066] Combination Figures 1 to 11 The reversing device 20 in this utility model may include a housing, an air distribution component 22, a sealing cover and a drive shaft. The air distribution component 22 may include a baffle 221 and a baffle plate 222. When the drive shaft rotates, it can drive the air distribution block to rotate. The air distribution block is set inside the housing and can block the first outlet 201, the second outlet 202 and the third outlet 203 on the housing accordingly.

[0067] Optionally, the baffle 222 has a perforated structure, and the end plate of the housing has an air inlet 208. During the rotation of the air distributor, when the perforated structure of the baffle 222 aligns with the air inlet 208, the circuit is open; otherwise, if the perforated structure of the baffle 222 is misaligned with the air inlet 208, the circuit is closed. The air distributor can have the following states during rotation:

[0068] State 1, i.e. the aforementioned first connected state: the hollow structure is connected to the air inlet 208, and the air distribution block blocks the second outlet 202 and the third outlet 203. At this time, the air inlet 208 is connected to the first outlet 201, or in other words, the air inlet 208 is connected to the drainage component 12, and the air pressure discharges the residual water in the drainage component 12 through the drain outlet via the air duct.

[0069] State 2, also known as the second connected state mentioned above: the hollow structure is connected to the air inlet 208, and the air distribution block blocks the third outlet. At this time, the air inlet is connected to the first outlet and the second outlet, or in other words, the air inlet 208 is connected to the drainage component 12 and the water cup.

[0070] Gas can enter the reversing device 20 through the air inlet. The perforated structure is connected to the air inlet 208, and the airflow leads to the bottom of the water cup 11. After the dishwasher 100 finishes its operation, a certain amount of residual water remains at the bottom of the water cup 11, which cannot be drained. If stored for a long time, this will cause bacterial growth and produce odors. This method removes the residual water at the bottom of the water cup 11 by blowing gas towards the drain assembly 12, then activating the drain pump to drain most of the water, and continuing to introduce gas into the water cup 11, simultaneously drying the bottom of the water cup 11, the cylindrical filter screen, and the cup handle.

[0071] State 3, the aforementioned third connected state: the hollow structure is connected to the air inlet 208, and the air distribution block blocks the first outlet 201 and the second outlet 202. At this time, the air inlet is connected to the third outlet 203. Through the reversing device 20, when the dishwasher 100 is in the drying stage, the blowing device directly introduces gas through the air inlet 208. This gas can be hot gas, which helps with drying. The gas enters the washing pump 131 directly through the reversing device 20, and then reaches the top spray arm 1331, the middle spray arm 1332, and the lower spray arm 1333 through internal pipes. The top spray arm 1331, the middle spray arm 1332, and the lower spray arm 1333 are equipped with drive holes. Under the action of airflow, the drive holes can drive the spray arms to rotate. At the same time, gas is ejected from the nozzles on the spray arms, directly spraying onto the tableware and blowing away water droplets. At this time, the rotating spray arms can evenly spray gas onto the tableware from all directions. By maintaining the airflow for a certain period of time, the gas can dry the tableware and remove any residual water inside the pipes. This significantly reduces drying time and improves the drying effect.

[0072] State 4, i.e., the aforementioned medium state: the perforated structure is disconnected from the air inlet 208, the air inlet 208 is closed, and the air distributor 22 blocks the first outlet 201. At this time, the second outlet 202 is connected to the first outlet 201.

[0073] Use case: This reversing device 20 is used for the drying of the air introduced into the dishwasher 100. When the dishwasher 100 is working normally, the water flow will pass through the reversing device 20. The reversing device 20 does not need to introduce air. It only needs to connect the second outlet 202 and the third outlet 203 so that the machine can wash normally and water will not enter the air inlet 208, as in state 4.
