Detailed Implementation

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 the present invention, and should not be construed as limiting the present invention.

[0027] The drying system 100 according to an embodiment of the present invention can be used in a dishwasher.

[0028] Combination Figure 1 and Figure 2 The drying system 100 includes a water cup 10, a washing pump 20, and an air blowing device 30. The washing pump 20 is connected to the water cup 10 and has a pump housing 21, a water inlet 22, and a water outlet 23. The washing pump 20 has an inlet side 20a and an outlet side 20b, with the water inlet 22 located on the inlet side 20a and the water outlet 23 located on the outlet side 20b. Exemplarily, when the washing pump 20 operates, it drives water from the water cup 10 into the spray arm of the dishwasher and sprays it out from the spray arm to clean dishes, etc. During operation, water enters the pump housing 21 from the water inlet 22 and is delivered to the spray arm from the water outlet 23. The air blowing device 30 is connected to the water outlet side 20b or downstream of the water outlet side 20b, and is used to blow air into the pump housing 21. Specifically, the air blowing device 30 can be connected to the water outlet side 20b of the washing pump 20, or the air blowing device 30 can be connected downstream of the water outlet side 20b of the washing pump 20. For example, the air blowing device 30 can be directly connected to the washing pump 20, or the air blowing device 30 can be connected to the washing pump 20 through a pipeline. It is understood that after the dishwasher completes the washing operation, the pump housing 21 of the washing pump 20 usually contains residual water. The air blowing device 30 blows air into the pump housing 21, providing positive pressure to the pump housing 21, which can accelerate the flow and evaporation of the residual water in the pump housing 21, thereby drying the washing pump 20 and preventing residual water from accumulating in the pump housing 21 and causing bacteria growth and odors.

[0029] According to the drying system 100 of this utility model embodiment, by providing an air blowing device 30 to blow air into the pump housing 21, the washing pump 20 can be dried, avoiding residual water from accumulating in the pump housing 21 and affecting the washing pump 20, as well as preventing bacteria from growing and odors from being generated in the residual water during long-term storage of the dishwasher.

[0030] The air blowing device 30 blows air into the pump housing 21, providing positive pressure to the pump housing 21. For example, the air blowing device 30 can be an air pump or a fan. The air blowing device 30 blows air into the pump housing 21, which can blow residual water towards the water cup 10 by providing positive pressure to the pump housing 21; or, the pump housing 21 can be provided with a drain outlet to drain the residual water in the pump housing 21, thereby improving the drying efficiency of the washing pump 20.

[0031] Additionally, the air blowing device 30 is connected to the outlet side 20b or downstream of the outlet side 20b. For example, the side wall of the pump housing 21 may be provided with an air inlet, and the air blowing device 30 is connected to the air inlet to blow air into the pump housing 21; or, the air blowing device 30 may be connected to the outlet 23, and air may be blown into the pump housing 21 through the outlet 23 of the washing pump 20. The air blowing device 30 may be directly connected to the outlet 23, or the air blowing device 30 may be connected to the outlet 23 through a pipeline.

[0032] The drying system 100 may include, but is not limited to, the following embodiments.

[0033] Implementation Method 1

[0034] The pipe wall of the outlet 23 is provided with a first air inlet, and the air blowing device 30 is connected to the first air inlet. Specifically, the air blowing device 30 can blow air into the pump housing 21 through the first air inlet, providing positive pressure into the pump housing 21, accelerating the flow and evaporation of residual water in the pump housing 21, and realizing the drying of the washing pump 20. By setting the first air inlet on the pipe wall of the outlet 23 and blowing air into the pump housing 21 through the air blowing device 30, the structure of the drying system 100 can be simplified, the modification of the existing washing pump 20 structure can be reduced, and the drying of the washing pump 20 can be achieved.

[0035] Optionally, the water outlet 23 can be connected to a water distribution valve. The water inlet of the water distribution valve is connected to the water outlet 23, and the water outlet can be connected to the spray arm. The first air inlet is located on the pipe wall of the water outlet 23. Air can also be blown onto the spray arm through the first air inlet to remove residual water from the washing pump 20 and the spray arm at the same time, thereby drying the washing pump 20 and the spray arm. When air is blown onto the spray arm, the evaporation of moisture on the surface of the tableware can be accelerated, thereby improving the drying efficiency of the tableware.

[0036] Implementation Method 2

[0037] Combination Figure 3The dishwasher's drying system 100 also includes a water outlet pipe 40 connected to a water outlet 23. The water outlet pipe 40 is provided with a second air inlet 41, and an air blowing device 30 is connected to the second air inlet 41. Specifically, the air blowing device 30 blows air into the pump housing 21 through the second air inlet 41, providing positive pressure to the pump housing 21, accelerating the flow and evaporation of residual water in the pump housing 21, thereby drying the washing pump 20. By placing the second air inlet 41 in the water outlet pipe 40 and blowing air into the pump housing 21 through the air blowing device 30, the structure of the drying system 100 can be simplified, eliminating the need to modify the existing structure of the washing pump 20, and achieving the drying of the washing pump 20.

[0038] Implementation Method 3

[0039] A third air inlet is provided on the side wall of the water outlet side 20b of the pump casing 21. The air blowing device 30 is connected to the third air inlet. For example, the pump casing 21 may have a pump chamber, in which the residual water of the washing pump 20 mainly accumulates. By providing the third air inlet on the side wall of the water outlet side 20b, it is convenient to blow air into the pump chamber through the air blowing device 30, thereby improving the drying efficiency of the washing pump 20. In addition, the third air inlet is arranged separately from the water outlet 23, which can reduce the impact of the washing pump 20 on the air blowing device 30 when water is discharged.

[0040] Optionally, the pump housing 21 may be provided with a drain outlet. The air blowing device 30 accelerates the discharge of fluid from the drain outlet by providing positive pressure into the pump housing 21, facilitating the drainage of residual water inside the pump housing 21 and improving the drying efficiency of the washing pump 20. The drain outlet may be connected to an external drain pipe for direct discharge to the outside of the dishwasher; alternatively, the drain outlet may be connected to a bypass water cup 10, meaning that water discharged from the drain outlet can enter the water cup 10 and be discharged to the outside of the dishwasher through the drainage system of the water cup 10.

[0041] In some embodiments of this utility model, the drying system 100 of the dishwasher further includes a water distribution valve and a spray arm assembly. One end of the water distribution valve is connected to the water outlet pipe 40, and the other end is connected to the spray arm assembly. A second air inlet 41 is located on the water outlet pipe 40 between the water outlet 23 and the water distribution valve. An air blowing device 30 blows air toward the water outlet 23 and the water distribution valve. Specifically, during the washing process, the washing pump 20 pumps fluid to the water outlet 23 and distributes it to the spray arm assembly via the water distribution valve to clean the dishes. After the washing program ends, the air blowing device 30 blows air toward the water outlet 23 to provide positive pressure into the pump housing 21 to dry the washing pump 20. The air blowing device 30 also blows air toward the water distribution valve to provide positive pressure into the spray arm assembly to dry the spray arm assembly, preventing residual water from accumulating inside the spray arm assembly and causing bacteria to grow. At the same time, the airflow blown out by the spray arm assembly can also accelerate the evaporation of moisture on the surface of the dishes, facilitating the drying of the dishes. In other words, the air blowing device 30 operates to dry the washing pump 20, the spray arm assembly, and the dishes, reducing the impact of residual water in the dishwasher on the dishes.

[0042] For example, the spray arm assembly may include an upper spray arm, a middle spray arm, and a lower spray arm. Those skilled in the art will understand that, in different washing stages of the dishwasher, water flow can be switched to different spray arms according to actual needs via a water distribution valve. The air blowing device 30 blows air to the water distribution valve, which can precisely control the direction of airflow. For example, the water distribution valve can control the airflow to flow to the upper spray arm first, drying the upper spray arm and the dishes near the upper spray arm. At this time, the water in the upper spray arm and on the dishes can enter the water cup 10 under the action of gravity. Then, the water distribution valve controls the airflow to flow to the middle spray arm, and finally to the lower spray arm, which can improve the drying effect of the dishwasher.

[0043] Combination Figure 3 In some embodiments of this utility model, the air blowing device 30 includes a fan 31 and a first one-way valve 32. The first one-way valve 32 is connected between the fan 31 and the pump housing 21 and is used to control the airflow from the fan 31 to the pump housing 21 in one direction. Under the action of the first one-way valve 32, the airflow blown out by the fan 31 can only enter the pump housing 21 in one direction, thereby improving the blowing efficiency of the fan 31 and preventing the water flow or airflow in the washing pump 20 from entering the fan 31 when negative pressure is generated in the washing pump 20, which would affect the fan 31 and improve the reliability of the drying system 100.

[0044] Combination Figure 3 In some embodiments of this utility model, the drying system 100 may include a water outlet pipe 40 connected to a water outlet 23. The water outlet pipe 40 is provided with a second air inlet 41. The air blowing device 30 also includes an air inlet pipe 33, one end of which is connected to a fan 31, and the other end is connected to the second air inlet 41. For example, during the washing process, the washing pump 20 pumps fluid to the water outlet 23 and distributes it to the spray arm assembly through a water distribution valve to clean the tableware. By placing the second air inlet 41 in the water outlet pipe 40 and blowing air into the pump housing 21 through the air blowing device 30, the structure of the drying system 100 can be simplified, the modification of the existing washing pump 20 structure can be reduced, and the drying of the washing pump 20 can be achieved. The airflow blown out by the blower 31 passes through the air inlet pipe 33 and enters the pump housing 21 through the second air inlet 41, which improves the stability of the airflow. In addition, the air inlet pipe 33 connects the blower 31 and the second air inlet 41, which can optimize the installation position of the blower 31 and improve the space utilization of the dishwasher. For example, the air inlet pipe 33 can be set as a rubber hose.

[0045] The first one-way valve 32 is located on the air inlet pipe 33, which facilitates the control of the airflow of the blowing device 30 into the pump housing 21 through the first one-way valve 32, and prevents water from entering the blowing device 30 from the water outlet pipe 40 during the washing process, thereby improving the reliability of the drying system 100.

[0046] Combination Figure 5 In some embodiments of this utility model, the fan 31 is located above the water outlet pipe 40. The position of the fan 31 is relatively higher than that of the water outlet pipe 40. When the water from the washing pump 20 is introduced into the spray arm through the water outlet pipe 40, the water in the water outlet pipe 40 will not enter the fan 31, thus avoiding water entering the fan 31 and affecting the fan 31, thereby improving the reliability of the drying system 100.

[0047] In some embodiments of this utility model, the blower 31 is an axial flow blower 31, which makes the structure of the blowing device 30 compact and can provide a larger air volume, making it easier for the blowing device 30 to provide high-speed airflow into the pump housing 21 and improve the drying efficiency of the washing pump 20.

[0048] In addition, in some embodiments, the air blowing device 30 can also be connected to a water distribution valve to blow air onto the spray arm assembly. By setting the fan 31 as an axial flow fan 31, a high-speed airflow can be provided to the spray arm assembly, improving the drying efficiency of the spray arm assembly. Furthermore, the airflow blown out by the spray arm assembly can also accelerate the evaporation of moisture on the surface of the tableware.

[0049] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the pump housing 21 includes a first drain outlet 211. The air blowing device 30 drives the fluid in the pump housing 21 to be discharged from the first drain outlet 211. The air blowing device 30 provides positive pressure to the pump body to accelerate the flow efficiency of the residual water in the pump housing 21, so that the residual water in the pump housing 21 can be quickly discharged from the first drain outlet 211. By directly opening a drain outlet on the pump housing 21, the discharge efficiency of the residual water in the pump housing 21 can be improved, thereby improving the drying efficiency of the washing pump 20.

[0050] Combination Figure 5 The dishwasher's drying system 100 also includes a bypass channel 50. One end of the bypass channel 50 is connected to the first drain outlet 211, and the other end is connected to the water cup 10. Specifically, residual water from the washing pump 20 can enter the water cup 10 from the first drain outlet 211 through the bypass channel 50. In other words, when the blowing device 30 is working, it can discharge the residual water from the washing pump 20 to the water cup 10 through the bypass channel 50, reducing the impact of residual water on the washing pump 20 and simplifying the structure of the drying system 100, eliminating the need for a separate drain pipe for the washing pump 20.

[0051] Combination Figure 5 and Figure 6Optionally, the water cup 10 assembly also includes a drain pump 60. The water cup 10 has a second drain outlet 11 connected to the drain pump 60. For example, residual water from the washing pump 20 enters the water cup 10 under the action of the air blowing device 30, and enters the water cup through the first drain outlet 211, and is then discharged to the outside of the dishwasher by the drain pump 60. This facilitates the installation and compact design of the dishwasher, and also facilitates the discharge of residual water in the washing pump 20 through the water cup 10, thereby improving the drying efficiency of the drying system 100.

[0052] Optionally, the first drain outlet 211 can be located on the bottom wall of the pump housing 21, allowing water to be discharged from the pump body more easily under the influence of gravity. The first drain outlet 211 may be equipped with a control valve or a one-way valve, etc., to prevent washing water from being discharged from the first drain outlet 211 during the washing process.

[0053] Optionally, the first drain outlet 211 is equipped with a second one-way valve. The dishwasher's drying system 100 has a first operating mode and a second operating mode. In the first operating mode, the air blowing device 30 operates and connects to the pump housing 21, and the second one-way valve is open. In the second operating mode, the air blowing device 30 is disconnected from the pump housing 21, and the second one-way valve is closed. For example, the first operating mode can be a drying mode, and the second operating mode can be a washing mode. In the drying mode, the air blowing device 30 connects to the pump housing 21 and blows air into the pump housing 21. The second one-way valve is open, allowing residual water in the pump housing 21 to be discharged from the first drain outlet 211 under positive pressure, thus accelerating the drying efficiency of the washing pump 20. In the washing mode, the air blowing device 30 is disconnected from the pump housing 21, and the second one-way valve is closed. The washing pump 20 can drive the fluid entering through the inlet to flow from the outlet to the spray arm.

[0054] In some embodiments of this utility model, the drying system 100 of the dishwasher further includes a heating element configured to heat the airflow blown by the air blowing device 30 toward the water distribution valve, so that the spray arm assembly can blow out hot airflow. On the one hand, this can accelerate the drying efficiency of the spray arm assembly; on the other hand, the hot airflow blown out by the spray arm assembly can accelerate the evaporation of moisture on the surface of the tableware, facilitating rapid drying of the tableware and maintaining a dry environment inside the dishwasher. Exemplarily, the heating element can be disposed within the air blowing device 30, which may include a fan 31 and an air inlet pipe 33. One end of the air inlet pipe 33 is connected to the fan 31, and the other end blows air into the pump housing 21. For example, the heating element can be disposed downstream of the fan 31, or the heating element can be disposed within the air inlet pipe 33, facilitating the heating element to heat the airflow blown out by the fan 31.

[0055] This invention also proposes a dishwasher, including the aforementioned drying system 100. By setting up the drying system 100, the washing pump 20 can be dried, preventing residual water from accumulating inside the washing pump 20 and causing bacteria growth and odors, thus maintaining a good working environment for the dishwasher.
