[0023] 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.

[0024] Combination Figure 1 and Figure 2According to an embodiment of the present invention, a dishwasher 100 includes a body assembly, a spray assembly 40, and an air blowing assembly 20. Specifically, the spray assembly 40 is disposed on the body assembly, and the air blowing assembly 20 is connected to the spray assembly 40 and is used to pump airflow to the spray assembly 40. The spray assembly 40 can spray fluid or blow airflow into the body. When the spray assembly 40 sprays fluid, it can clean items inside the machine, such as tableware. When the air blowing assembly 20 pumps airflow into the spray assembly 40, the airflow can drive residual fluid in the spray assembly 40 to be discharged or blow away residual fluid. The airflow can also spray air into the body through the spray assembly 40, and the airflow can blow onto the tableware, thereby drying the water droplets on the surface of the tableware and achieving the drying of the tableware.

[0025] More specifically, the spray assembly 40 includes at least two spray arms distributed in the vertical direction, so that the two spray arms can act on the upper and lower parts of the machine body, which helps to expand the spray range and improve the spray effect.

[0026] Furthermore, the dishwasher 100 also includes a diversion valve 50 connected between the spray assembly 40 and the air blowing assembly 20. The diversion valve 50 is configured to switchably control one of the at least two spray arms to connect to the air blowing assembly 20, and to control at least two spray arms to connect to the air blowing assembly 20 together. Specifically, the airflow of the air blowing assembly 20 can enter the spray assembly 40 through the diversion valve 50. When the diversion valve 50 controls the flow of the spray arms of the spray assembly 40, the air blowing assembly 20 can control the air blowing mode of the spray assembly 40 according to the connection state between the diversion valve 50 and the spray arms, thereby controlling the drying mode of the dishwasher 100 and improving the drying efficiency.

[0027] For example, when the diversion valve 50 connects to one spray arm of the spray assembly 40, the air blowing assembly 20 can blow air onto that spray arm, and the airflow can be blown out through that spray arm. When the diversion valve 50 connects to at least two spray arms and the air blowing assembly 20, the airflow can be blown out from at least two spray arms. Thus, by placing the diversion valve 50 between the air blowing assembly 20 and the spray assembly 40, the drying effect of the air blowing assembly 20 on the spray assembly 40 can be improved.

[0028] In practical applications, the spray arm of the spray assembly 40 may be unused when the diversion valve 50 is not activated, and there may be no residual water inside. When blowing air, air can be blown onto a designated spray arm according to the activation status of the diversion valve 50, which helps to improve drying efficiency and save energy. Alternatively, at least two spray arms may contain residual water, or at least two spray arms may need to be blown to dry the tableware. In this case, the diversion valve 50 can first activate the upper spray arm, then activate the lower spray arm. This prevents water droplets from the upper spray arm from dripping downwards. Finally, at least two spray arms can be activated simultaneously to dry the tableware, thereby shortening the drying time and improving the drying effect.

[0029] The dishwasher 100 also includes a washing pump 10 and a water cup 30, the water cup 30 being connected to the water inlet of the washing pump 10, and an air blowing assembly 20 being connected between the washing pump 10 and the water cup 30. Thus, when the air blowing assembly 20 blows air, the airflow can flow to the water cup 30 and the washing pump 10, allowing the air blowing assembly 20 to blow air to the water cup 30 and the washing pump 10.

[0030] Specifically, the water cup 30 is connected to the washing pump 10 through a pipe, the air blowing assembly 20 is connected to the pipe or the air blowing port of the air blowing assembly 20 is connected to the pipe, and the washing pump 10 is connected to the diversion valve 50.

[0031] In conjunction with the foregoing, airflow can be blown onto the spray assembly 40 via the washing pump 10. That is, the air blowing assembly 20, or its air outlet, is located between the water outlet of the water cup 30 and the washing pump 10, enabling comprehensive drying of the dishwasher 100 and thus improving the functionality of the air blowing assembly 20. In other words, the dishwasher 100 only needs one air blowing assembly 20 to achieve drying, simplifying the structure while ensuring drying effectiveness. Specifically, airflow can enter the water cup 30 from the water outlet or water cup outlet 303, enter the washing pump 10 from the inlet, and then enter the spray arm of the spray assembly 40 through the diversion valve 50, and exit from the spray arm.

[0032] According to an embodiment of the present invention, the dishwasher 100 is provided with an air blowing assembly 20 that can blow air onto the spray assembly 40, the washing pump 10, and the water cup 30, thereby improving the drying effect of the dishwasher. Gas can be blown from the spray assembly 40 onto the tableware, achieving a drying effect on the spray assembly 40 and the tableware inside the machine. Furthermore, by placing a diversion valve 50 between the air blowing assembly 20 and the spray assembly 40, the diversion valve 50 can control the connection mode of at least two spray arms of the spray assembly 40, thereby reasonably controlling the blowing mode of the air blowing assembly 20, which is beneficial to improving the drying efficiency of the dishwasher 100.

[0033] It should be noted that the aforementioned spray arm can be either a rotating arm or a spray pipe. Specifically, the spray arm can be a spray arm that rotates and sprays water inside the dishwasher 100, or it can be a spray pipe connected inside the dishwasher 100 and having one or more nozzles.

[0034] In some embodiments of this utility model, at least two spray arms include a first spray arm 431 and a second spray arm 432. The first spray arm 431 is positioned above the second spray arm 432. The first spray arm 431 can be used to clean the upper space of the dishwasher 100, and the second spray arm 432 can be used to clean the lower space of the dishwasher 100, thereby improving the cleaning and drying effect of the tableware. Specifically, the diversion valve 50 includes a first state and a second state. In the first state, the diversion valve 50 controls the air blowing assembly 20 to connect to the first spray arm 431. In the second state, the diversion valve 50 controls the air blowing assembly 20 to connect to the second spray arm 432. That is, the diversion valve 50 can control the working loading of the first spray arm 431 and the second spray arm 432 respectively. In the first state, the diversion valve 50 can control the air blowing assembly 20 to blow air only to the first spray arm 431. In the second state, the diversion valve 50 controls the air blowing assembly 20 to blow air only to the second spray arm 432. For example, when the user places dishes only at the top or bottom of the dishwasher 100, only one spray arm can be turned on; when drying, only one spray arm can be ventilated.

[0035] Alternatively, the diversion valve 50 can be in the first state first and then in the second state, meaning the air blowing assembly 20 first blows air onto the first spray arm 431 and then onto the second spray arm 432. When the first spray arm 431 and the second spray arm 432 are cleaning simultaneously, both spray arms 431 and 432 contain residual water. When the air blowing assembly 20 is drying, the diversion valve 50 can be controlled in the first state first, allowing the air blowing assembly 20 to blow air onto the upper first spray arm 431, blowing out the residual water and allowing the airflow to continue blowing into the spray area of ​​the first spray arm 431, thus drying the tableware. Then, the diversion valve 50 can be in the second state, connecting the air blowing assembly 20 to the second spray arm 432, blowing out the residual water and allowing the airflow to continue blowing into the spray area of ​​the second spray arm 432, thus drying the tableware. This prevents water from the upper spray arm or water droplets from the upper tableware from falling downwards, thus improving the drying effect.

[0036] Furthermore, in some embodiments of this utility model, the diversion valve 50 also has a third state, in which the diversion valve 50 controls the air blowing assembly 20 to connect the first spray arm 431 and the second spray arm 432. In other words, when the diversion valve 50 is in the third state, the first spray arm 431 and the second spray arm 432 can be connected simultaneously. For example, the diversion valve 50 connects the air blowing assembly 20 with the first spray arm 431 and the second spray arm 432, so that the air blowing assembly 20 can blow air onto the first spray arm 431 and the second spray arm 432 at the same time, realizing the simultaneous drying of the first spray arm 431 and the second spray arm 432. Moreover, the airflow from the first spray arm 431 and the second spray arm 432 can be blown toward the tableware, so that the airflow from the air blowing assembly 20 can be blown toward the upper and lower parts of the dishwasher 100 at the same time, which helps to shorten the drying time. In conjunction with the foregoing, after drying the first spray arm 431 and the second spray arm 432, the diversion valve 50 can be adjusted to the third state so that the first spray arm 431 and the second spray arm 432 can blow air onto the tableware simultaneously, which helps to improve the drying efficiency.

[0037] Combination Figure 1 In order to further improve the cleaning and drying effect, in some embodiments of the present invention, the spray assembly 40 further includes a third spray arm 433, which is located below the second spray arm 432. Thus, in the dishwasher 100, the first spray arm 431, the second spray arm 432 and the third spray arm 433 can be located in the upper, middle and lower areas of the dishwasher 100, respectively, thereby further expanding the spraying range of the spray arm and reducing cleaning dead corners.

[0038] The diversion valve 50 also has a fourth state in which it controls the air blowing assembly 20 to connect to the third spray arm 433. This allows the air blowing assembly 20 to connect to the third spray arm 433, and the airflow can blow out the residual water in the third spray arm 433. The airflow is then continued to be blown into the spray range of the third spray arm 433, thereby drying the dishes at the bottom of the dishwasher 100.

[0039] Furthermore, in some embodiments of this invention, the diversion valve 50 also has a fifth state, in which the diversion valve 50 controls the air blowing assembly 20 to connect the first spray arm 431, the second spray arm 432, and the third spray arm 433. Thus, in the fifth state, the airflow of the air blowing assembly 20 can simultaneously blow onto the first spray arm 431, the second spray arm 432, and the third spray arm 433, and blow onto the tableware through the spray arms, which helps to improve the drying efficiency of the dishwasher 100.

[0040] In conjunction with the foregoing, when the spray assembly 40 has multiple spray arms, the diversion valve 50 can connect the air blowing assembly 20 to a single spray arm, or it can connect the air blowing assembly 20 to all spray arms.

[0041] Optionally, the diverter valve 50 may also have a sixth state in which the diverter valve 50 controls the air blowing assembly 20 to connect the second spray arm 432 and the third spray arm 433.

[0042] Optionally, the diversion valve 50 may also have a seventh state, in which the diversion valve 50 controls the air blowing assembly 20 to connect the first spray arm 431 and the third spray arm 433. That is to say, the diversion valve 50 can realize multiple control modes according to the actual cleaning situation of the dishwasher 100, so as to improve the flexibility of the air blowing assembly 20 and the spray arms, which is conducive to improving the drying effect, improving the drying efficiency, and saving energy.

[0043] Combination Figure 1 In some embodiments of this utility model, the spray arm is provided with a drive hole. The airflow from the blowing assembly 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 through the drive hole on the spray arm, which can be directly sprayed onto the tableware, blowing away water droplets on the tableware. 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 spray assembly 40 can be further expanded, improving the cleaning and drying effect.

[0044] In some other embodiments of this utility model, the spray arm can also 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 100, thereby drying the washing chamber of the dishwasher 100.

[0045] 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.

[0046] In some embodiments of this utility model, combined with Figure 2 and Figure 3The dishwasher 100 also includes a reversing assembly 60, which is connected to the water cup 30 and the washing pump 10 respectively. The reversing assembly 60 has an air inlet 601. The reversing assembly 60 has an air intake state and a connected state. In the connected state, the water cup 30 is connected to the water circuit of the washing pump 10, and the air inlet 601 is separated from the water cup 30 and the washing pump 10. In the air intake state, the air inlet 601 is connected to either the water cup 30 or the washing pump 10. Specifically, multiple air outlets can be connected to different components or parts so that the air blowing assembly 20 can blow air onto multiple components to dry them. One air outlet is connected to the washing pump 10. The air from the air blowing assembly 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 keeping the inside dry.

[0047] More specifically, the reversing assembly 60 can selectively connect or disconnect the air inlet 601 and the air outlet, controlling the connection and disconnection between the air blowing assembly 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 reversing assembly 60 can disconnect the air inlet 601 and the air outlet, separating the air blowing assembly 20 from the washing pump 10 and preventing washing water from the washing pump 10 from entering the air blowing assembly 20 through the air outlet, thus preventing contamination or damage to the air blowing assembly 20.

[0048] Optionally, the reversing assembly 60 can selectively connect the air inlet 601 to one or more of the multiple air outlets. In this way, when the blowing assembly 20 is working, gas can enter the reversing assembly 60 from the air inlet 601 and flow out from the multiple air outlets, realizing gas diversion, thereby blowing gas to multiple components at the same time, which helps to improve drying efficiency.

[0049] For example, one of the multiple air outlets can be connected to the water cup 30. When the reversing component 60 connects the air inlet 601 to the air outlet, the blowing component 20 can blow air into the water cup 30, thereby facilitating the drying of the water cup 30.

[0050] Specifically, the dishwasher 100 also includes a control valve connected to and controlling the reversing assembly 60. Thus, the control valve can be used to control one of the multiple air outlets of the reversing assembly 60 to be connected to the air inlet 601 or not connected to the air inlet 601.

[0051] Combination Figure 4In 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 diversion valve inlet 302. The water cup outlet 303 is connected to the inlet of the washing pump 10, and the diversion 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 of the washing pump 10 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 assembly 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 assembly 40. Specifically, when the dishwasher 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 diversion valve inlet 302, which is separated from the water storage chamber 310, or enters the diversion chamber 320 through the diversion valve inlet 302. The diversion valve inlet 302 is connected to the spray assembly 40. During washing, the diversion valve inlet 302 can also be used for water intake, which can send water to the spray assembly 40 and spray it out by the spray arm of the spray assembly 40.

[0052] Furthermore, combined Figure 3 and Figure 4 The water distribution chamber 320 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 the first spray arm 431, the second air outlet 322 is connected to the second spray arm 432, and the third air outlet 323 is connected to the 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.

[0053] Combination Figure 1 According to a specific embodiment of the dishwasher 100 of the present invention, the spray assembly 40 includes a pipe 41, a third air outlet 323 which can be directly connected to a third spray arm 432 located at the lower part, a first air outlet 321 and a second air outlet 322 are disposed in the pipe 41, and the pipe 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.

[0054] 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.

[0055] Combination Figure 1 and Figure 4 In some embodiments of this utility model, the reversing assembly 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 cavity 310, and can blow air into the water cup 30 to dry the water storage cavity 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 water inlet of the washing pump 10, which can dry the washing pump 10.

[0056] The air inlet 601 is connected to the air blowing assembly 20, so that the gas from the air blowing assembly 20 can enter the reversing assembly 60 from the air inlet 601. The reversing assembly 60 can send the blowing air into the water cup 30, the water storage chamber 310, the drainage channel 34, or the washing pump 10.

[0057] Optionally, the air inlet 601 can be selectively connected to one outlet or multiple outlets simultaneously.

[0058] In some embodiments of this utility model, combined with Figure 2 and Figure 4 The dishwasher 100 also includes a drain assembly 70. A drain outlet 304 is located at the bottom of the water cup 30, connected to the drain assembly 70 to drain water from the water cup 30. The drain outlet 304 is connected to a drain pipe 71, which directs the drain water to a predetermined location. After the water in the water cup 30 is drained, the air from the blowing assembly 20 can also be connected to the water storage chamber 310 of the water cup 30 via the reversing assembly 60, blowing air into the water storage chamber 310 to dry the water cup 30.

[0059] In some embodiments of this invention, the dishwasher 100 further includes a heating component configured to heat the airflow pumped by the air blowing component 20, thereby increasing the airflow temperature and improving drying efficiency. Specifically, the heating component is configured to heat the airflow blown by the air blowing component 20 towards the washing pump 10, making the airflow entering the washing pump 10 a hot airflow, accelerating the evaporation efficiency of residual water in the washing pump 10, and thus improving the drying efficiency of the washing pump 10, maintaining a dry environment in the washing pump 10. In conjunction with the foregoing, the heating component can also accelerate drying when the air blowing component 20 blows air towards the water cup 30 or the spray component 40, further improving the drying effect. The heating component can also be used to heat the washing water, thereby increasing the washing water temperature and enabling hot water washing, which can achieve sterilization and disinfection, and also helps dissolve stains, improving the cleaning effect.

[0060] Combination Figure 2 In some embodiments of this utility model, the air blowing assembly 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 is connected to the air inlet 601 of the reversing assembly 60. Specifically, 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 connecting the fan 21 and the air inlet 601 optimizes the installation position of the fan 21 and improves the space utilization of the dishwasher 100. 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.

[0061] In some embodiments of this utility model, the blower 21 is an axial flow blower 21, which makes the structure of the air blowing assembly 20 compact and can provide a larger air volume, making it easier for the air blowing assembly 20 to provide high-speed airflow to the washing pump 10 and improve the drying efficiency of the washing pump 10.

[0062] In some embodiments of this utility model, the air blowing assembly 20 is connected to a one-way valve. The one-way valve is configured to be unidirectional in the air blowing direction. That is, under the action of the one-way valve, the airflow blown by the air blowing assembly 20 can only enter the washing pump 10, the spray assembly 40, or the water cup 30 in one direction. This can improve the air blowing efficiency of the air blowing assembly 20 and prevent the airflow or water flow in the washing pump 10 from flowing back into the air blowing assembly 20 when the washing pump 10 generates negative pressure, thus affecting the service life of the air blowing assembly 20 and improving the reliability of the dishwasher 100. For example, the air blowing assembly 20 may include a fan 21 and an air inlet pipe 22. The air inlet pipe 22 connects the outlet and the air inlet 601 of the fan 21. The one-way valve may be installed at the outlet of the fan 21 or connected to the air inlet pipe 22.

[0063] Combination Figure 1 and Figure 2According to a specific embodiment of the dishwasher 100 of this utility model, the air blowing assembly 20 can be disposed between the water cup 30 and the washing pump 10 of the dishwasher 100. Through the reversing assembly 60, when the dishwasher 100 is in the drying stage, gas is directly introduced through the air inlet 601. This gas can be hot gas, which aids in drying. The gas enters the washing pump 10 through the reversing assembly 60, and then through the diversion valve 50, it is introduced into the internal pipe of the spray assembly 40, reaching the top spray arm (first spray arm 431), the middle spray arm (second spray arm 432), and the lower spray arm (third spray arm 433), respectively. The top spray arm, middle spray arm, and lower spray arm are provided with driving holes. Under the action of airflow, the driving holes can drive the spray arms to rotate. Simultaneously, gas is ejected from the spray holes on the spray arms, directly spraying onto the tableware to dry water droplets and residual water. The rotating spray arms can evenly spray gas onto the tableware from all directions, improving the blowing effect. At this point, the airflow switching valve 50 is first switched. In its first state, the airflow is delivered to the top spray arm, blowing away water droplets from the top layer of dishes. Then, the valve is switched to its second state, delivering air to the middle spray arm to dry the water droplets from the middle layer of dishes. This process is repeated, with the valve switched to its fourth state, delivering air to the lower spray arm to blow away water droplets from the bottom layer of dishes. Finally, the valve is switched to its fifth state, simultaneously directing air into the top, middle, and lower spray arms, while the heating element is activated to heat the air. This allows the hot air to evenly dry any residual moisture on the dishes and water droplets on the inner walls of the dishwasher 100, thus shortening the drying time and improving the drying effect.
