[0026] 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.

[0027] Combination Figure 1 and Figure 2The drying system 100 of the dishwasher according to an embodiment of the present invention includes: a spray device 40 and an air blowing device 20. The air blowing device 20 is provided with an air blowing port, which is connected to the spray device 40 and adapted to blow air into the spray device 40. Specifically, when the spray device 40 is performing a cleaning operation, it can spray washing water or clean water onto items to be cleaned, such as tableware, to achieve a cleaning effect. After cleaning, there will still be residual water inside the spray device 40. The residual water is not easy to evaporate inside the spray device 40, causing the inside of the spray device 40 to remain in a damp state for a long time, which can easily produce bacteria or odors and reduce the cleanliness of the spray device 40. The air blowing device 20 is connected to the spray device 40, so that after spraying, the air blowing device 20 can blow air into the spray device 40. Thus, the airflow can drive the fluid out of the spray device 40 or dry the residual water inside the spray device 40, thereby achieving a drying effect and improving the cleanliness of the spray device 40.

[0028] Furthermore, the air blowing device 20 continues to supply air to the spray device 40, and the airflow can be sent out through the spray device 40, allowing the airflow to be further directed towards the tableware, achieving a drying effect. Specifically, water droplets remain on the surface of the washed tableware. Since the tableware is inside the dishwasher, the water droplets on the surface of the tableware take a long time to dry naturally, and the environment inside the dishwasher is humid, making it easier for bacteria to grow. Specifically, in related technologies, the drying system of a dishwasher can only dry the tableware inside the cavity, while in the drying system of this application, the air blowing device 20 can dry both the tableware and the inside of the spray device.

[0029] In addition, since the air blowing device 20 and the cleaning water flow path are the same, and both the airflow and water flow of the air blowing device 20 flow through the spray device 40, the spray device 40 sprays water and blows air over the same range. This allows the air blowing device 20 to dry the water droplets left on the surface of the tableware when the spray device 40 sprays water, thus improving the drying effect on the tableware.

[0030] Furthermore, combined Figure 4 In some embodiments of this utility model, the drying system 100 includes a diversion valve 50, which is connected between the air blowing device 20 and the spraying device 40 and connects or disconnects the air blowing device 20 and the spraying device 40. Specifically, the airflow of the air blowing device 20 can enter the spraying device 40 through the diversion valve 50. When the diversion valve 50 controls the flow of the spraying device 40, the air blowing device 20 can blow air into the spraying device 40 according to the connection state of the diversion valve 50 and the spraying device 40, thereby improving the drying efficiency of the air blowing device 20.

[0031] For example, when the diversion valve 50 is only connected to a portion of the spray device 40, the air blowing device 20 can blow air onto that portion. Therefore, by positioning the diversion valve 50 between the air blowing device 20 and the spray device 40, the drying effect of the air blowing device 20 on the spray device 40 can be improved. In other words, the portion of the diversion valve 50 not connected to the spray device 40 contains no residual water. During air blowing, air can be blown onto the spray device 40 according to the on / off state of the diversion valve 50, which helps to improve drying efficiency and save energy.

[0032] More specifically, in some embodiments of this invention, the spray device 40 includes multiple spray arms arranged at intervals, and the diversion valve 50 selectively connects or disconnects the air outlet with one or more spray arms. Thus, when the diversion valve 50 connects the air outlet with one spray arm, the blowing device can blow air only onto that spray arm. When the diversion valve 50 connects the air outlet with multiple spray arms, the blowing device 20 can blow air onto multiple spray arms simultaneously. In other words, the diversion valve 50 can control the connection or disconnection between the blowing device 20 and multiple spray arms; for example, the diversion valve 50 can control which spray arm the blowing device blows air onto, or blow air onto one spray arm first, then another, etc. Therefore, the drying system 100 can have multiple drying modes to adapt to different application conditions or cleaning states of the spray device 40, thereby improving the drying effect.

[0033] In some embodiments of this utility model, the drying system 100 includes a washing pump 10, and an air blowing port is connected to the upstream of the washing pump 10. Specifically, when the air blowing port is connected to the upstream of the washing pump 10, the airflow can pass through the washing pump 10 when the air blowing port blows, thereby achieving the drying of the washing pump 10. Thus, the airflow direction of the air blowing device 20 can be consistent with the flow direction of the water, driving the fluid to be discharged, making the washing and drying process more thorough.

[0034] Furthermore, the washing pump 10 is connected to the diversion valve 50, so that the gas from the blowing device 20 can flow from the washing pump 10 to the diversion valve 50, and then enter the spray device 40 through the diversion valve 50, thereby blowing air onto the spray device 40 and the tableware to improve the drying effect.

[0035] More specifically, combined Figure 1 Connecting the air outlet to the upstream of the washing pump 10 also facilitates the air blowing device 20's proximity to other components, allowing it to connect to multiple components simultaneously, thereby improving both the blowing and cleaning effects. For example, when the air outlet is connected to the upstream of the washing pump 10, the drying system 100 may include a water cup 30, which can be connected to the inlet of the washing pump 10 via a pipe, with the air blowing device 20 connected to the pipe or its air outlet connected to the pipe.

[0036] Combination Figure 3In some embodiments of this utility model, the air outlet is located on the washing pump 10. When the air blowing device 20 is working, the airflow from the air outlet can first enter the washing pump 10, driving the fluid inside the washing pump 10 to be discharged or drying the washing pump 10. Then, the airflow can enter the spray device 40 from the washing pump 10, discharging the fluid inside the spray device 40, thus drying the spray device 40. The airflow from the air blowing device 20 can also be blown out from the spray arm of the spray device 40 and blown towards the tableware, thereby drying the tableware. For example, in some embodiments of this utility model, the washing pump 10 is provided with a vent, and the air blowing device 20 is connected to the vent. Thus, gas can directly enter the washing pump 10 from the vent, which is beneficial to improving the ventilation or blowing effect. Specifically, the air blowing device can be directly connected to the washing pump 10, so that the air blowing device 20 can be connected to the body of the washing pump 10.

[0037] According to the drying system 100 of this utility model embodiment, the air blowing device 20 blows air into the washing pump 10 and the spray device 40, and the air blowing device 20 is connected to the spray device 40 through a diversion valve. The air blowing device 20 can be controlled to blow air into the spray device 40, and the gas can also be blown from the spray device 40 to the tableware. This can dry the tableware in the washing pump 10, the spray device 40 and the dishwasher, which helps to improve the cleanliness of the spray device 40 and the drying efficiency of the tableware.

[0038] Combination Figure 1 In some embodiments of this utility model, the multiple spray arms include a first spray arm 431, a second spray arm 432, and a third spray arm 433 distributed along the vertical direction. The three spray arms are spaced apart along the vertical direction, which can expand the spray range of the spraying device 40 and improve the cleaning effect. Specifically, the diversion valve 50 can control the air outlet to connect to one or more of the first spray arm 431, the second spray arm 432, and the third spray arm 433. For example, when the diversion valve 50 connects the air outlet to the first spray arm 431, the air blowing device 20 can blow air onto the first spray arm 431; when the diversion valve 50 connects the air outlet to the second spray arm 432, the air blowing device 20 can blow air onto the second spray arm 432. Alternatively, the diversion valve 50 can connect the air outlet to both the first spray arm 431 and the second spray arm 432, allowing the air blowing device 20 to blow air onto both the first spray arm 431 and the second spray arm 432 simultaneously. In other words, the diversion valve 50 can be located between the air outlet and multiple spray arms, enabling the switching of air blowing modes among the multiple spray arms. This allows the air blowing device 20 to select one or more spray arms to blow air according to the actual situation, thereby achieving multiple drying methods. For example, when there is water in multiple spray arms, the diversion valve 50 can first connect the first spray arm 431 located at the top to dry the first spray arm 431 first, and then connect the second spray arm 432 to dry the second spray arm 432. This can prevent the water in the first spray arm 431 from dripping downwards, which helps to improve the drying efficiency.

[0039] According to the drying system 100 of this utility model embodiment, the spraying device 40 includes a pipeline, which includes a first branch 421, a second branch 422, and a third branch 423 extending laterally. A first spray arm 431, a second spray arm 432, and a third spray arm 433 are respectively connected to and rotatably connected to the first branch 421, the second branch 422, and the third branch 423, with the first direction perpendicular to the second direction. Thus, the first spray arm 431, the second spray arm 432, and the third spray arm 433 can be arranged at intervals along the vertical direction, and are respectively located at the upper, middle, and lower parts of the dishwasher. The first spray arm 431, the second spray arm 432, and the third spray arm 433 are rotatable, allowing for rotating spraying of washing water during spraying, thus improving the cleaning effect. Specifically, the first spray arm 431 and the second spray arm 432 can clean the dishes located at the upper part of the dishwasher, while the second spray arm 432 and the third spray arm 433 can be used to clean the dishes located at the lower part of the dishwasher.

[0040] Specifically, the pipeline includes a main line 41 and multiple branches. The main line 41 extends along a first direction, and the multiple branches are spaced apart along the main line 41 along the first direction. The multiple branches also extend along a second direction, with the first direction perpendicular to the second direction. This allows the washing water to be delivered in both directions, increasing the spray area and improving the flexibility of the spray arm arrangement. Specifically, the first direction can be vertical or the height of the dishwasher, and the second direction can be horizontal or the width of the dishwasher. That is, the main line 41 extends along the height of the dishwasher, and the branches connect to the main line 41 and extend along the width. This allows the washing water to fully contact the tableware located in different positions within the dishwasher. For example, the dishwasher's inner drum can have upper and lower shelves for placing tableware, and during washing, the washing water can be delivered to the upper and lower parts of the dishwasher through the pipeline.

[0041] In some embodiments of this utility model, combined with Figure 2 and Figure 4 The drying system 100 has a water distribution chamber 320, which is provided with a first air outlet 321, a second air outlet 322, and a third air outlet 323. The first air outlet 321 is connected to a first spray arm 431, the second air outlet 322 is connected to a second spray arm 432, and the third air outlet 323 is connected to a third spray arm 433. A diversion valve 50 is disposed in the water distribution chamber 320 and can selectively connect or disconnect the air outlet from one or more of the first air outlet 321, the second air outlet 322, and the third air outlet 323. For example, the diversion valve 50 can connect or disconnect the air outlet from the spray arm by blocking the first air outlet 321, the second air outlet 322, and / or the third air outlet 323 with a baffle.

[0042] Combination Figure 1According to a specific embodiment of the drying system 100 of the present invention, the third air outlet 323 can be directly connected to the third spray arm 432 located at the lower part. The first air outlet 321 and the second air outlet 322 are located in the main channel 41. The main channel 41 is provided with a channel that separately connects the first air outlet 321 and the first spray arm 431, as well as the second air outlet 322 and the second spray arm 432, thereby realizing the diversion of the first spray wall 431 and the second spray arm 432.

[0043] Optionally, the diversion valve 50 can also be used to connect or disconnect the water supply to the first spray arm 431, the second spray arm 432 and the third spray arm 433, thereby controlling the spraying mode of the spraying device 40.

[0044] Combination Figure 1 In some embodiments of this utility model, the spray arm is provided with a drive hole. The airflow from the blowing device 20 drives the spray arm to rotate around the vertical axis. Specifically, the drive hole, under the action of the airflow, drives the spray arm to rotate. At the same time, gas is ejected from the nozzles on the spray arm, which can directly spray onto the tableware and blow away water droplets. At this time, the rotating spray arm can evenly spray gas onto the tableware from all directions. By maintaining the blowing for a certain period of time, the gas can dry the tableware and blow away residual water inside the spray arm, greatly shortening the drying time and improving the drying effect. More specifically, the rotation of the spray arm along the vertical axis can expand the range of air or water spraying upward and / or downward. When multiple spray arms can be arranged in the vertical direction, the range of air or water spraying by the spraying device 40 can be further expanded, improving the cleaning and drying effect.

[0045] In some other embodiments of this invention, the spray arm is a spray pipe, which can be configured to rotate around a horizontal axis. When the spray arm rotates, it can spray air or water around itself, thereby achieving a drying and cleaning effect. The spray arm can be configured to rotate around a horizontal axis, and when spraying air, the gas can also be sprayed or blown towards the inner wall of the dishwasher, thereby drying the dishwasher's washing chamber.

[0046] In other words, the spray arm can be in the form of extending horizontally, and the driving force of air or water spray can drive the spray arm to rotate about a vertical axis. The spray arm can also be in the form of extending vertically, such as a nozzle, which can be electrically driven to rotate along a horizontal axis, thereby spraying air or water around the nozzle.

[0047] Furthermore, the drying system 100 includes a check valve 23, which is located between the vent and the air blowing device 20 and is configured to allow unidirectional flow in the air blowing direction. That is, the connection between the washing pump 10 and the air blowing device can be adjusted via the valve. For example, in conjunction with... Figure 3 The air blowing device 20 is connected to a check valve 23, which is located between the air inlet and the air blowing device 20.

[0048] In some embodiments of this utility model, the drying system 100 includes a washing pump 10, and an air blowing port can be located between the washing pump 10 and the diversion valve 50, so that the air blowing device 20 can blow air to the washing pump 10 and also blow air to the spray device 40 through the diversion valve 50. The air blowing device 20 can dry the washing pump 10, the spray device 40, and the tableware, which helps to improve the functionality of the air blowing device 20 and improve the drying effect and drying efficiency. For example, the washing pump 10 may have an outlet, and a pipe may be provided between the outlet of the washing pump 10 and the diversion valve 50. The air blowing port is connected to the pipe, thereby realizing the supply of air to the washing pump 10 and the spray device 40. A one-way valve or a check valve may be installed in the air blowing device 20 to realize the one-way flow of air.

[0049] Combination Figure 2 In some embodiments of this utility model, the drying system 100 further includes a water cup 30 connected to the washing pump 10. An air outlet is located between the water outlet of the water cup 30 and the washing pump 10. Thus, when the air blowing device 20 blows air, the airflow can flow to both the water cup 30 and the washing pump 10, allowing the air blowing device 20 to blow air onto both the water cup 30 and the washing pump 10. In conjunction with the aforementioned, the airflow can also be directed to the spray device 40 via the washing pump 10. In other words, by positioning the air outlet of the air blowing device 20 between the water outlet of the water cup 30 and the washing pump 10, the entire system can be dried, thereby improving the functionality of the air blowing device 20. In other words, the drying system 100 only requires one air blowing device 20 to achieve the drying of the dishwasher, simplifying the structure while ensuring drying effectiveness. Specifically, the airflow can enter the water cup 30 from the water outlet 30 or the water cup outlet 303, enter the washing pump 10 from the inlet of the washing pump 10, and enter the spray arm of the spray device 40 through the diversion valve 50, and be blown out from the spray arm.

[0050] Furthermore, combined Figure 2 The drying system 100 also includes a gas distribution valve 60, which has an air inlet 601 and multiple air outlets. An air blowing device 20 is connected to the air inlet 601. One air outlet is connected to a water cup 30, and another air outlet is connected to a washing pump 10. The gas distribution valve 60 is configured to selectively connect and disconnect the air outlets from the air inlet 601. Specifically, the multiple air outlets can be connected to different devices or components so that the air blowing device 20 can blow air onto multiple devices to achieve a drying effect on multiple devices. One air outlet is connected to the washing pump 10, and the gas from the air blowing device 20 flows from the air inlet 601 to the air outlet and then enters the washing pump 10, thereby driving the fluid inside the washing pump 10 to be discharged and maintaining internal dryness.

[0051] More specifically, the air distribution valve 60 can selectively connect or disconnect the air inlet 601 and the air outlet, controlling the connection and disconnection between the air blowing device 20 and the washing pump 10, thereby improving operational reliability. For example, when the washing pump 10 is in the washing state, it contains a large amount of washing water. The air distribution valve 60 can disconnect the air inlet 601 and the air outlet, separating the air blowing device 20 from the washing pump 10 and preventing washing water from the washing pump 10 from entering the air blowing device 20 through the air outlet, thus preventing contamination or damage to the air blowing device 20.

[0052] Optionally, the gas distribution valve 60 can selectively connect the air inlet 601 to one or more of the multiple air outlets. In this way, when the blowing device 20 is working, gas can enter the gas distribution valve 60 from the air inlet 601 and flow out from the multiple air outlets, realizing the gas diversion. This allows gas to be blown to multiple devices at the same time, which helps to improve drying efficiency.

[0053] For example, one of the multiple air outlets can be connected to the water cup 30. When the air distribution valve 60 connects the air inlet 601 to the air outlet, the air blowing device 20 can blow air into the water cup 30, thereby facilitating the drying of the water cup 30.

[0054] Specifically, the drying system 100 also includes a control valve, which is connected to and controls the gas distribution valve 60. Thus, the control valve can be used to control which of the multiple gas outlets of the gas distribution valve 60 is connected to the inlet 601 or not connected to the inlet 601.

[0055] Combination Figure 5In some embodiments of this utility model, the water cup 30 includes a water storage chamber 310 and a water distribution chamber 320, which are separated. The water storage chamber 310 has a water cup outlet 303, and the water distribution chamber 320 has a water distribution valve inlet 302. The water cup outlet 303 is connected to the inlet of the washing pump 10, and the water distribution valve inlet 302 is connected to the outlet of the washing pump 10. The water distribution chamber 320 is connected to the outlet or downstream of the washing pump 10. That is, the inlet of the washing pump 10 is connected to the water storage chamber 310, and the outlet is connected to the water distribution chamber 320. The water distribution chamber 320 is connected between the outlet of the washing pump 10 and the spray device 40. When the washing pump 10 is working, it draws water from the water storage chamber 310, pressurizes it, and sends it to the water distribution chamber 320, which then enters the spray device 40. Specifically, when the drying system 100 is working, the pump body of the washing pump 10 draws water from the water storage chamber 310 of the water cup 30. The drawn water is discharged from the water cup 30, that is, it enters the inlet of the washing pump 10 from the water cup outlet 303. After the water is pressurized in the washing pump 10, it is sent from the outlet of the washing pump 10 to the water distribution valve inlet 302, which is separated from the water storage chamber 310. The water distribution valve inlet 302 is connected to the spray device 40. During washing, the water distribution valve inlet 302 can also be used for water intake, which can send water to the spray device 40 and spray it out by the spray arm of the spray device 40.

[0056] In some embodiments of this utility model, combined with Figure 2 and Figure 3 The drying system 100 also includes a drainage device 70. A drain outlet 304 is located at the bottom of the water cup 30, and the drain outlet 304 is connected to the drainage device 70 to drain the water from the water cup 30. After drainage, a drain pipe 71 is connected, which can guide the drained water to a predetermined location. After the water in the water cup 30 is drained, the gas from the air blowing device 20 can also be connected to the water storage chamber 310 of the water cup 30 through the air distribution valve 60, blowing air into the water storage chamber 310 to dry the water cup 30.

[0057] Combination Figure 1 and Figure 5 In some embodiments of this utility model, the air distribution valve 60 is provided with an air inlet 601, a first outlet, a second outlet, and a third outlet; the water cup 30 is provided with a water cup outlet 303 and a drain channel 34. The first outlet is connected to the water cup outlet 303, which is connected to the water storage chamber 310, and can blow air into the water cup 30 to dry the water storage chamber 310. The second outlet is connected to the drain channel 34, which can dry the drain channel 34 of the water cup 30. The third outlet is connected to the inlet of the washing pump 10, which can dry the washing pump 10.

[0058] The air inlet 601 is connected to the air blowing device 20, so that the gas from the air blowing device 20 can enter the air distribution valve 60 from the air inlet 601. The air distribution valve 60 can send the blown air into the water storage chamber 310 of the water cup 30, or the drainage channel 34, or the washing pump 10.

[0059] Optionally, the air inlet 601 can be selectively connected to one outlet or multiple outlets simultaneously.

[0060] In some embodiments of this invention, the drying system 100 further includes a heating component. This heating component heats the gas blown out by the air blowing device 20, increasing the airflow temperature and thus improving drying efficiency. Specifically, the heating component is configured to heat the airflow blown by the air blowing device 20 towards the washing pump 10, making the airflow entering the washing pump 10 a hot airflow. This accelerates the evaporation efficiency of residual water in the washing pump 10, thereby improving the drying efficiency of the washing pump 10 and maintaining a dry environment. In conjunction with the foregoing, the heating component can also accelerate drying when the air blowing device 20 blows air towards the water cup 30 or the spray device 40, further improving the drying effect. The heating component can also be used to heat the washing water, thereby increasing its temperature and enabling hot water washing. This provides a sterilization and disinfection effect, and also helps dissolve stains, improving the cleaning effect.

[0061] Combination Figure 2 and Figure 3 In some embodiments of this utility model, the air blowing device 20 includes a fan 21 and an air inlet pipe 22. One end of the air inlet pipe 22 is connected to the fan 21, and the other end blows air towards the air outlet. The airflow generated by the fan 21 enters the washing pump 10 through the air inlet pipe 22, improving the stability of the airflow. Furthermore, the air inlet pipe 22 connects the fan 21 and the air inlet 601, optimizing the installation position of the fan 21 and improving the space utilization of the dishwasher. For example, the air inlet pipe 22 can be configured as a flexible hose for easy arrangement. For example, the air inlet pipe 22 extends to a certain length, forming an air duct within it.

[0062] In some embodiments of this utility model, the blower 21 is an axial flow blower 21, which makes the structure of the blowing device 20 compact and can provide a larger air volume, making it easier for the blowing device 20 to provide high-speed airflow to the washing pump 10 and improve the drying efficiency of the washing pump 10.

[0063] In some embodiments of this utility model, the air blowing device 20 is connected to a one-way valve, which is configured to allow airflow to flow unidirectionally from the air blowing device 20 to the washing pump 10. Specifically, the one-way valve is configured to allow unidirectional flow along the blowing direction, meaning that under the action of the one-way valve, the airflow blown out by the air blowing device 20 can only enter the washing pump 10 in one direction, improving the blowing efficiency of the air blowing device 20 and preventing the airflow or water flow inside the washing pump 10 from flowing back into the air blowing device 20 when the washing pump 10 generates negative pressure, thus affecting the service life of the air blowing device 20 and improving the reliability of the drying system 100. The one-way valve can also prevent air from entering the washing pump 10, which would affect the pump's efficiency; therefore, the one-way valve can also protect the washing pump 10.

[0064] For example, the air blowing device 20 may include a blower 21 and an air inlet pipe 22, the air inlet pipe 22 being connected to the outlet and air inlet 601 of the blower 21, and a one-way valve may be installed at the outlet of the blower 21 or connected to the air inlet pipe 22.

[0065] According to the present invention, the dishwasher includes the aforementioned drying system 100. By providing the aforementioned drying system 100 inside the dishwasher, the blowing device 20 can blow air onto the spray device 40 and blow air into the dishwasher through the spray device 40, thereby achieving the drying of the spray device 40 and the tableware inside the dishwasher and improving the cleaning effect of the dishwasher.
