Commercial dishwasher can be divided into cabinet dishwasher, cover dishwasher, basket transmission dishwasher, belt transmission dishwasher, ultrasonic dishwasher and other five categories, which reduces the labor intensity of the cooks in the restaurant, hotel, government unit canteen, improves the work efficiency, and improves the cleanliness.

[0033] Taking the cabinet dishwasher as an example, the dishwasher in the prior art usually includes a cabinet, a sprayer, an air inlet fan and an air outlet fan. The inside of the cabinet forms an inner cavity, and the inner cavity is a working cavity. The front end of the cavity of the cabinet is provided with a cabinet door for taking and placing tableware. The cabinet is provided with a sprayer inside, and the sprayer is installed on a sprayer seat and can freely move relative to the sprayer seat. A water guide pipe is connected with the sprayer for sending water to the sprayer. The existing dishwasher basically completes the air circulation in the dishwasher through an air inlet fan and an air outlet fan. This kind of drying method has the problems of relatively low drying efficiency, and residual water in the waterway, which affects the user experience.

[0034] Therefore, it is urgent to develop a dishwasher which can solve the above problems.

[0035] Figure 1 is a schematic sectional view of the dishwasher of an embodiment of the present application. As Figure 1As shown, in order to solve the problems of relatively low drying efficiency and residual water in the waterway in the prior art, the present application provides a dishwasher 100, which generally comprises a cabinet 1 and an inner cavity 2 formed in the cabinet 1, and the inner cavity 2 is a working cavity. The dishwasher 100 further comprises at least one sprayer 3, a water guide pipe 4, a blowing device 5, a main air duct 6 and a conventional air duct 7. The at least one sprayer 3 is arranged in the inner cavity 2. The water guide pipe 4 is connected with the at least one sprayer 3 in correspondence, and the water guide pipe 4 is configured to guide water or send air. The blowing device 5 is used to introduce air flow into the inner cavity 2 of the dishwasher 100. The blowing device 5 can be a fan, and can also be a blower. The main air duct 6 is connected with the air outlet of the blowing device 5, and the main air duct 6 is also connected with the water guide pipe 4. The conventional air duct 7 is connected with the air outlet of the blowing device 5, and the conventional air duct 7 is also connected with the at least one sprayer 3. Among them, the at least one sprayer 3 is configured to wash tableware, and the at least one sprayer 3 is also configured to dry the tableware under the action of the blowing device 5.

[0036] The sprayer 3 is internally provided with a cavity for containing water or gas, and the lower surface of the sprayer 3 is provided with a plurality of hole positions in communication with the cavity. When water flows in the sprayer 3, the tableware can be sprayed and cleaned. When air flow flows in the sprayer 3, the gas can be released to increase the air circulation in the inner cavity 2 to dry the tableware.

[0037] The dishwasher 100 of the present application comprises at least one sprayer 3, a water guide pipe 4, a blowing device 5, a main air duct 6 and a conventional air duct 7, the water guide pipe 4 is connected with the at least one sprayer 3 in correspondence, the main air duct 6 is connected with the air outlet of the blowing device 5, the main air duct 6 is also connected with the water guide pipe 4, the conventional air duct 7 is connected with the air outlet of the blowing device 5, and the conventional air duct 7 is also connected with the at least one sprayer 3, so that the at least one sprayer 3 is configured to wash tableware, and the at least one sprayer 3 is also configured to dry the tableware under the action of the blowing device 5. By increasing the main air duct 6 and the conventional air duct 7 in the inner cavity 2 of the dishwasher 100, the main air duct 6 is connected with the water guide pipe 4, the conventional air duct 7 is connected with the sprayer 3, by selecting different working conditions, using the blowing device 5 to send air flow to the main air duct 6 and the water guide pipe 4, or to the conventional air duct 7 and the main air duct 6 and the water guide pipe 4, that is, to the sprayer 3 and out of the plurality of hole positions of the sprayer 3, to increase the air flow in the dishwasher 100, improve the drying efficiency, and also accelerate the evaporation of residual water in the water guide pipe 4 and the sprayer 3. Therefore, the dishwasher 100 of the present application improves the drying efficiency, solves the problem of residual water in the waterway, and further improves the user experience.

[0038] As a possible embodiment, dishwasher 100 further includes a three-phase conduction valve 8 having three branches, each of which is provided with a corresponding valve. Three-phase conduction valve 8 is connected to the main air duct 6, the conventional air duct 7, and the air outlet of the blowing device 5. Switching between the three operating modes is achieved by opening and closing the corresponding valves of three-phase conduction valve 8.

[0039] More specifically, the three branch ports of the three-phase conduction valve 8 include a first branch port located at the bottom, and second and third branches located at the top. The second and third branches correspond to the right and left sides of the three-phase conduction valve 8. The first branch port is connected to the air outlet of the blowing device 5, the second branch port is connected to the main air duct 6, and the third branch port is connected to the conventional air duct 7. Switching between the three operating modes is achieved by opening or closing the valves corresponding to the three branch ports of the three-phase conduction valve 8. The terms "up," "down," "left," and "right" are defined based on the view the reader is viewing.

[0040] In a specific implementation, when the dishwasher 100 enters the drying stage, the three-phase conduction valve 8 enters different conduction states according to different programs selected by the user.

[0041] As a possible implementation method, the three working conditions include the first working condition. When the selected program drying stage time is shorter, all three valves of the three-phase conduction valve 8 are opened, and the blowing device 5 blows out the air flow, passes through the three-phase conduction valve 8 into the conventional air duct 7 and the main air duct 6, and is then blown out by the sprayer 3.

[0042] Specifically, the blowing device 5 starts working, the valves corresponding to the first branch port, the second branch port and the third branch port of the three-phase conduction valve 8 are opened, and the blowing power is increased at the same time. A stronger airflow will enter the second branch port and the third branch port of the three-phase conduction valve 8 through the first branch port of the three-phase conduction valve 8, enter the conventional air duct 7 through the third branch port and then enter the sprayer 3, enter the main air duct 6 through the second branch port and then enter the sprayer 3 through the water inlet pipe 4, so that the gas flow in the inner cavity 2 of the dishwasher 100 is more frequent and the drying efficiency is higher.

[0043] As a possible implementation method, the three working conditions include the second working condition. When the selected program drying stage time is longer, the valve corresponding to the conventional air duct 7 in the three-phase conduction valve 8 is closed and the other valves are opened. The airflow generated by the blowing device 5 enters the main air duct 6 through the corresponding valve and is blown out by the sprinkler 3 through the water pipe 4.

[0044] Specifically, the blowing device 5 starts working, the valves corresponding to the first and second branches of the three-phase conduction valve 8 are opened, and the valve corresponding to the third branch is closed. The airflow enters the second branch through the first branch of the three-phase conduction valve 8, enters the main air duct 6 through the second branch, and then enters the water pipe 4 through the main air duct 6 to the sprinkler 3, and then flows out through the hole of the sprinkler 3. Figure 1The dotted arrow indicates the direction of air flow.

[0045] As a possible implementation, the three working conditions include a third working condition, in which when the selected program does not include a drying process, the three valves of the three-phase conduction valve 8 are all closed, and the blowing device 5 does not work.

[0046] Specifically, the blowing device 5 does not work, and the three valves corresponding to the first branch port, the second branch port and the third branch port of the three-phase conduction valve 8 are in a non-conducting state.

[0047] In specific implementation, the valve can be a ball valve, a solenoid valve or an electric control valve.

[0048] As a possible embodiment, the dishwasher 100 also includes a controller (not shown in the figure), which is configured to control the opening or closing of the three valves corresponding to the first branch, the second branch and the third branch of the three-phase conduction valve 8, and the controller is also configured to control the opening or closing of the blowing device 5.

[0049] In a specific implementation, the controller can be a main controller of the dishwasher 100 or a separate controller. The controller can be implemented by a chip or by a chip and a control circuit.

[0050] As a possible implementation, see Figure 1 The number of the sprayers 3 is three, and the three sprayers 3 are vertically stacked and arranged in the inner cavity 2. Through the above arrangement, not only a good spraying effect can be achieved but also space can be saved.

[0051] Of course, in other embodiments, the three sprayers 3 may be arranged in a staggered manner or in other arrangements.

[0052] See also Figure 1 Each sprayer 3 can also be installed in the inner cavity 2 of the cabinet 1 in a foldable manner. When spraying or drying is required, the sprayer 3 is moved to a position and opened. After the work is completed, the sprayer 3 is folded back to its original position. In this way, interference caused by taking and placing tableware can be avoided.

[0053] As a possible implementation, Figure 1 As shown, three sprayers 3 are arranged in the inner cavity 2 at upper, middle and lower positions, namely forming a top sprayer 3, a middle sprayer 3 and a bottom sprayer 3.

[0054] More specifically, if Figure 1As shown, three sprinklers 3 are disposed on the right side of the inner cavity 2 and are arranged vertically stacked to form a top sprinkler 3, a middle sprinkler 3, and a bottom sprinkler 3. The water conduit 4 connects the top sprinkler 3, the middle sprinkler 3, and the bottom sprinkler 3 through three water diversion branches: the upper water diversion branch, the middle water diversion branch, and the lower water diversion branch. The conventional air duct 7 connects the top sprinkler 3, the middle sprinkler 3, and the bottom sprinkler 3 through conventional air duct branches: the upper conventional air duct branch, the middle conventional air duct branch, and the lower conventional air duct branch. When long drying time is required, the blowing device 5 starts to work, and the air flow enters the main air duct 6 through the first branch port and the second branch port of the three-phase conduction valve 8 and then enters the water diversion pipe 4, and then enters the top sprayer 3, the middle sprayer 3 and the lower sprayer 3 through the upper water diversion branch, the middle water diversion branch and the lower water diversion branch, and then flows out through the corresponding holes of the top sprayer 3, the middle sprayer 3 and the lower sprayer 3, thereby increasing the air circulation inside the dishwasher 100 and improving the drying efficiency. At the same time, it also accelerates the evaporation of residual water in the water diversion pipe 4 and the residual water in the top sprayer 3, the middle sprayer 3 and the lower sprayer 3. When short-term drying is required, the blowing device 5 starts to work, and the air flow enters the second and third branches through the first branch of the three-phase conduction valve 8. The air flow enters the main air duct 6 through the second branch and then enters the water diversion pipe 4. Then, it enters the top sprinkler 3, the middle sprinkler 3 and the lower sprinkler 3 through the upper water diversion branch, the middle water diversion branch and the lower water diversion branch, and then flows out through the corresponding holes of the top sprinkler 3, the middle sprinkler 3 and the lower sprinkler 3. The air flow also enters the conventional The air flows through the air duct 7, and then enters the top sprayer 3, the middle sprayer 3 and the lower sprayer 3 through the upper conventional air duct branch, the middle conventional air duct branch and the lower conventional air duct branch, and then flows out through the corresponding holes of the top sprayer 3, the middle sprayer 3 and the lower sprayer 3, thereby further increasing the air circulation inside the dishwasher 100 and improving the drying efficiency. At the same time, it also accelerates the evaporation of the residual water in the water pipe 4 and the residual water in the top sprayer 3, the middle sprayer 3 and the lower sprayer 3.

[0055] More specifically, see Figure 1 According to actual conditions, the blowing power of the blowing device 5 can be increased to generate a stronger airflow, which can cause the top sprayer 3, the middle sprayer 3 and the lower sprayer 3 to rotate, making the gas flow inside the dishwasher 100 more sufficient.

[0056] As a possible implementation, see Figure 1 The number of the sprayers 3 is two, and the two sprayers 3 are arranged vertically in the inner cavity 2. As a possible embodiment, see Figure 1 , two sprayers 3 are arranged in the inner cavity 2 according to the upper and middle positions, that is, forming a top sprayer 3 and a middle sprayer 3.

[0057] More specifically, see Figure 1 Two sprayers 3 are disposed on the right side of the inner cavity 2 and arranged vertically stacked, forming a top sprayer 3 and a middle sprayer 3. A water conduit 4 connects the top and middle sprayers 3, respectively, through an upper and middle water conduit branch. A conventional air duct 7 connects the top and middle sprayers 3, respectively, through an upper and middle conventional air duct branch. When extended drying is required, the blowing device 5 activates, and air flows through the first and second branches of the three-phase conduction valve 8 into the main air duct 6, then into the water conduit 4. Air then flows through the upper and middle water conduit branches into the top and middle sprayers 3, and out through the corresponding holes in the top and middle sprayers 3. This increases air circulation within the dishwasher 100, improving drying efficiency and accelerating the evaporation of residual water in the water conduit 4 and in the top and middle sprayers 3. When short-term drying is required, the blowing device 5 starts to work, and the air flow enters the second branch and the third branch through the first branch of the three-phase conduction valve 8. The air flow enters the main air duct 6 through the second branch and then enters the water diversion pipe 4, and then enters the top sprayer 3 and the middle sprayer 3 through the upper water diversion branch and the middle water diversion branch, and then flows out through the corresponding holes of the top sprayer 3 and the middle sprayer 3. The air flow also enters the conventional air duct 7 through the third branch, and then enters the top sprayer 3 and the middle sprayer 3 through the upper conventional air duct branch and the middle conventional air duct branch, and then flows out through the corresponding holes of the top sprayer 3 and the middle sprayer 3, further increasing the air circulation inside the dishwasher 100 and improving the drying efficiency. At the same time, it also accelerates the evaporation of residual water in the water diversion pipe 4 and the residual water in the top sprayer 3 and the middle sprayer 3.

[0058] As a possible implementation, see Figure 1 There are two sprayers 3 , and the two sprayers 3 are arranged vertically stacked in the inner cavity 2 .

[0059] As a possible implementation, see Figure 1 , two sprayers 3 are arranged in the inner cavity 2 according to upper and lower positions, that is, forming a top sprayer 3 and a bottom sprayer 3.

[0060] More specifically, see Figure 1Two sprayers 3 are disposed on the right side of the inner cavity 2 and arranged vertically stacked, forming a top sprayer 3 and a lower sprayer 3. A water conduit 4 connects the top and lower sprayers 3, respectively, through an upper water inlet branch and a lower water conduit branch. A conventional air duct 7 connects the top and lower sprayers 3, respectively, through an upper conventional air duct branch and a lower conventional air duct branch. When extended drying is required, the blowing device 5 activates, and air flows through the first and second branches of the three-phase conduction valve 8 into the main air duct 6, then into the water conduit 4. Air then flows through the upper and lower water conduit branches into the top and lower sprayers 3, respectively, and out through the corresponding holes in the top and lower sprayers 3. This increases air circulation within the dishwasher 100, improving drying efficiency and accelerating the evaporation of residual water in the water conduit 4 and in the top and lower sprayers 3. When short-term drying is required, the blowing device 5 starts to work, and the air flow enters the second branch and the third branch through the first branch of the three-phase conduction valve 8. The air flow enters the main air duct 6 through the second branch and then enters the water diversion pipe 4, and then enters the top sprayer 3 and the lower sprayer 3 through the upper water diversion branch and the lower water diversion branch, and then flows out through the corresponding holes of the top sprayer 3 and the lower sprayer 3. The air flow also enters the conventional air duct 7 through the third branch, and then enters the top sprayer 3 and the lower sprayer 3 through the upper conventional air duct branch and the lower conventional air duct branch, and then flows out through the corresponding holes of the top sprayer 3 and the lower sprayer 3, further increasing the air circulation inside the dishwasher 100 and improving the drying efficiency. At the same time, it also accelerates the evaporation of residual water in the water diversion pipe 4 and the residual water in the top sprayer 3 and the lower sprayer 3.

[0061] As a possible implementation, see Figure 1 , the number of the sprayer 3 is one, which is arranged in the inner cavity 2. As a possible embodiment, see Figure 1 , a sprinkler 3 is arranged at the upper position, namely forming the top sprinkler 3.

[0062] More specifically, see Figure 1 , a sprinkler 3 is arranged on the right side of the inner cavity 2, thus forming a sprinkler 3 at the top. The water guide pipe 4 is connected to the sprinkler 3 at the top, and the conventional air duct 7 is connected to the sprinkler 3 at the top. When long-term drying is required, the blowing device 5 starts to work, and the air flow enters the main air duct 6 through the three-phase conduction valve 8 and then enters the water guide pipe 4, and then flows out through the holes of the sprinkler 3. When short-term drying is required, the blowing device 5 starts to work, and the air flow enters the main air duct 6 through the three-phase conduction valve 8 and then enters the water guide pipe 4, and then flows out through the holes of the sprinkler 3. The air flow also enters the conventional air duct 7 through the three-phase conduction valve 8 and then enters the sprinkler 3, and then flows out through the holes of the sprinkler 3.

When long-time drying is needed, the air blowing device 5 starts to work, and the air flow enters the main air duct 6 through the three-phase on-off valve 8, then enters the water pipe 4, and finally flows out through the holes of the spray nozzle 3. When short-time drying is needed, the air blowing device 5 starts to work, and the air flow enters the main air duct 6 through the three-phase on-off valve 8, then enters the water pipe 4, and finally flows out through the holes of the spray nozzle 3. The air flow also enters the conventional air duct 7 through the three-phase on-off valve 8, then enters the spray nozzle 3, and finally flows out through the holes of the spray nozzle 3.

[0064] As a possible implementation, the number of the spray nozzles 3 is one, which is arranged in the inner cavity 2.

Figure 1 As a possible implementation, the number of the spray nozzles 3 is one, which is arranged in the inner cavity 2. As a possible implementation, one spray nozzle 3 is arranged in the middle part, i.e. the spray nozzle 3 in the middle part. More specifically, one spray nozzle 3 is arranged on the right side of the inner cavity 2, which is the spray nozzle 3 in the middle part.
