[0051] Washing dishes is an essential part of daily life. The oil stains on the dishes can easily lead to greasy hands. At the same time, people's pace of life is getting faster and faster, and the cleaning efficiency is low and the time is long during the daily dishwashing process. Therefore, dishwashers are increasingly widely used in people's daily lives.

[0052] In the related art, a dishwasher is a device that can spray hot or cold water onto dishes to remove dirt adhering to the dishes and clean the dishes. When in use, the dishes are placed in the basket of the dishwasher. The dishwasher includes a washing pump that sprays washing water, a spray arm, and a heater that generates hot water. The washing pump sprays washing water into the basket of the dishwasher to clean the dishes. The sprayer of the dishwasher is usually fixed on the basket and connected to the water supply pipeline at the rear through a plug-in structure. In order to ensure the spray pressure and cleaning effect, a good sealing structure is generally designed to reduce leakage pressure loss.

[0053] However, after the dishwasher finishes washing the dishes, some cleaning water will remain in the pipe. When the user pulls out the bowl basket, the above-mentioned sealing structure will be destroyed, causing the residual water in the pipe to spill onto the dried dishes in the bowl basket or outside the dishwasher, resulting in a poor user experience.

[0054] Based on this, the present application provides a dishwasher that can solve the problem that residual water in the dishwasher spills onto dried tableware in the bowl basket or outside the dishwasher, resulting in a poor user experience. The specific structural features and effects of the dishwasher provided by the present application will be described in detail below in conjunction with the drawings in the specification.

[0055] Figure 1 FIG. 1 shows one of the overall structural diagrams of the dishwasher provided in the embodiment of the present application, referring to FIG. Figure 1 The utility model provides a dishwasher 1, which may include a dishwasher body 10, and the dishwasher body 10 has a dishwasher inner cavity 11.

[0056] In some embodiments of the present application, the dishwasher 1 may further include a bowl basket assembly 20, which may include at least one bowl basket, which is disposed in the inner cavity 11 of the dishwasher 1, so that the user can place items to be washed, such as bowls, plates, chopsticks or spoons, in the bowl basket.

[0057] It should be noted that when the inner cavity 11 of the dishwasher is provided with a plurality of bowl baskets, such as a first bowl basket 21 and a second bowl basket 22 arranged up and down, the items to be washed can be classified and placed in the bowl basket assembly 20, bowls, plates or tea cups can be placed in the upper first bowl basket 21, and chopsticks, spoons or knives and forks can be placed in the lower second bowl basket 22, so as to facilitate the user to store and organize after washing.

[0058] In some embodiments of the present application, the dishwasher 1 may further include a spray assembly 30, which is also disposed in the inner cavity 11 of the dishwasher 1 and is used to spray washing water toward the bowl basket, thereby washing the dishes in the bowl basket. The spray assembly 30 may also be provided in multiple groups, so that washing water can be sprayed toward the bowl basket from different directions to improve the washing effect of the dishes. The specific structure of the spray assembly 30 is as follows: Figure 2 shown.

[0059] Figure 2 FIG. 1 shows one of the structural schematic diagrams of the spray assembly provided in the embodiment of the present application, see FIG. Figure 2 The spray assembly 30 may include a spray pipe 31, one end of which is used to access external washing water.

[0060] Figure 3 The second structural schematic diagram of the spray assembly provided in the embodiment of the present application is shown. Figure 4 The structural diagram of the connecting shaft provided in the embodiment of the present application is shown in conjunction with Figure 3 and Figure 4 ,

[0061] In some embodiments of the present application, the spray assembly 30 may further include a connecting shaft 32, the other end of the spray pipe 31 is connected to the connecting shaft 32, and the outer peripheral surface of the connecting shaft 32 is provided with a plurality of water outlet holes 321 connected to the spray pipe 31, and the connection method between the spray pipe 31 and the connecting shaft 32 may be as follows: Figure 3 The threaded connection shown may also be a clamping connection or welding, etc., which is not limited here, as long as the relative positions of the two can be fixed.

[0062] Figure 5 FIG. 1 shows one of the structural schematic diagrams of the spray arm provided in the embodiment of the present application, and FIG. Figure 2 and Figure 5 In some embodiments of the present application, the spray assembly 30 may further include a spray arm 33, which is rotatably connected to the connecting shaft 32 and has a water storage chamber 331 connected to the water outlet hole 321, and a plurality of spray holes 332 spaced apart on the spray arm 33 and connected to the water storage chamber 331.

[0063] In this way, after the washing water in the spray pipe 31 enters the connecting shaft 32, it is injected into the water storage chamber 331 in the spray arm 33 through the water outlet hole 321 on the connecting shaft 32. When the water pressure in the water storage chamber 331 reaches a certain level, the washing water can be sprayed out from the spray hole 332 on the spray arm 33. At the same time, the spray arm 33 rotates around the connecting shaft 32 so that the spray range of the washing liquid can fully cover the bowl basket (such as Figure 1 ), thereby improving the cleaning effect of the dishes in the bowl basket.

[0064] Figure 6 The second structural diagram of the spray arm 33 provided in the embodiment of the present application is shown in conjunction with Figure 2 and Figure 6 In some embodiments of the present application, the spray assembly 30 may further include an abutment plate 34, which is disposed below the spray arm 33 and connected to the end of the connecting shaft 32 away from the spray pipe 31. The spray arm 33 is provided with a pre-drain port 333 on one side facing the abutment plate 34. In this way, the washing water in the water storage chamber 331 can be drained through the pre-drain port 333 on the spray arm 33 that is connected to the water storage chamber 331. For details, please refer to Figure 7-10 Related instructions.

[0065] Figure 7 The schematic diagram of the structure of the spray arm provided in the embodiment of the present application when in the first position is shown. Figure 8 Shows Figure 7 The enlarged structural diagram at position A is shown in conjunction with Figure 6 , Figure 7 and Figure 8The spray arm 33 in the present application can move along the axial direction of the connecting shaft 32, and the spray arm 33 has a first position. When the spray arm 33 is in the first position, it can be applied to the washing stage of the dishwasher 1, and the abutment plate 34 can abut against the pre-discharge port 333.

[0066] In this way, the abutment plate 34 can seal the water storage chamber 331 to prevent the washing water in the water storage chamber 331 from leaking downward, thereby ensuring that the water storage chamber 331 has a high water pressure, so that the washing water flows out from the spray hole 332 (such as Figure 2 When the liquid is sprayed toward the tableware (as shown), it has a higher impact force, which is beneficial for removing stains attached to the tableware, thereby achieving a better washing effect.

[0067] Fig. 9 The schematic diagram of the structure of the spray arm provided in the embodiment of the present application when in the second position is shown. Fig.10 Shows Fig. 9 The enlarged structural diagram at position B is shown in conjunction with Figure 6 , Fig. 9 and Fig.10 When the spray arm 33 is in the second position, it can be used in the drying stage of the dishwasher 1. When the washing stage of the dishwasher 1 is completed, the spray arm 33 moves downward from the first position to the second position. At this time, the abutment plate 34 is no longer abutted against the pre-drain port 333, and the two are separated from each other to form a drainage gap.

[0068] In this way, the washing water remaining in the spray pipe 31, the spray arm 33 and other pipes of the dishwasher 1 during the washing stage can be discharged in advance through the above-mentioned drainage gap, so that after the drying stage is completed, there will be no residual water spilling when the user pulls out the bowl basket.

[0069] In summary, the present application provides a pre-drain hole on the side of the spray arm 33 facing the abutment plate 34, and the spray arm 33 can move along the axial direction of the connecting shaft 32 to switch between the first position and the second position. When the spray arm 33 is in the first position, the abutment plate 34 located below the spray arm 33 and connected to the connecting shaft 32 abuts against the pre-drain hole 333 to seal the water storage chamber 331 in the spray arm 33, preventing the washing water in the water storage chamber 331 from leaking downward, and ensuring that the water storage chamber 331 has a high water pressure; when the spray arm 33 is in the second position, the abutment plate 34 and the pre-drain hole 333 are separated from each other to form a drainage gap, and the residual washing water in the spray pipe 31, the spray arm 33 and other pipes can be emptied in advance through the drainage gap, preventing the residual washing water from spilling on the dried dishes or outside the dishwasher 1 when the user pulls out the bowl basket, thereby effectively improving the actual user experience.

[0070] In order to enable the spray arm 33 to switch between the first position and the second position along the axial direction of the connecting shaft 32, in some embodiments of the present application, the spray assembly 30 may also include an elastic member, one end of the elastic member can abut against the abutment plate 34, and the other end of the elastic member can abut against the spray arm 33.

[0071] When the elastic member is in a first compression state, the spray arm 33 is located at a first position; when the elastic member is in a second compression state, the spray arm 33 is located at a second position, and the compression length of the elastic member in the first compression state is less than the compression length in the second compression state.

[0072] It can be understood that when the dishwasher 1 is in the washing stage, the spray pipe 31 injects water into the water storage chamber 331 of the spray arm 33. As the amount of water injected increases, the spray arm 33 overcomes the elastic force of the elastic member under the action of gravity and moves toward the abutment plate 34 until it reaches the first position. The abutment plate 34 seals the pre-discharge port 333 located below the spray arm 33.

[0073] When the dishwasher 1 is in the drying stage, the spray pipe 31 no longer injects water into the water storage chamber 331 of the spray arm 33. The washing water in the water storage chamber 331 is sprayed out through the spray hole 332, so that the amount of water injected into the water storage chamber 331 continues to decrease until the elastic force of the elastic member is greater than the sum of the washing water in the spray arm 33 and the water storage chamber 331. At this time, the elastic potential energy of the elastic member is converted into kinetic energy for driving the spray arm 33 to move upward until it reaches the second position and the abutment plate 34 and the pre-discharge port 333 are separated from each other.

[0074] In this way, the elastic potential energy of the elastic member is cleverly utilized, and combined with the different gravitational potential energies of the spray arm 33 of the dishwasher 1 in the washing stage and the drying stage (including the washing water in the spray arm 33), the spray arm 33 can be easily switched between the first position and the second position.

[0075] In addition, after the drainage gap between the abutment plate 34 and the pre-drain port 333 is formed, as the washing water in the water storage chamber 331 is discharged, the difference between the elastic potential energy of the elastic member and the gravitational potential energy of the spray arm 33 increases continuously, making the drainage gap larger, thereby accelerating the outflow of the washing water. In other words, the above process can form a positive feedback regulation, which can realize the rapid emptying of the residual washing water.

[0076] There are many specific configurations of the elastic member. Fig.11 One of the structural schematic diagrams of the elastic member provided in the embodiment of the present application is shown, Fig.12 A second schematic diagram of the structure of the elastic member provided in an embodiment of the present application is shown.

[0077] For example, see Fig.11In some embodiments of the present application, the elastic member may include a plurality of elastic protrusions 35, the plurality of elastic protrusions 35 are connected to the abutment plate 34, and / or the plurality of elastic protrusions 35 are connected to the spray arm 33 away from the spray pipe 31 (such as Figure 2 As shown) on one side, and around the connecting shaft 32 (as shown Figure 2 In this way, the plurality of circumferentially spaced elastic protrusions 35 sandwiched between the abutment plate 34 and the spray arm 33 can provide a stable elastic force to the spray arm 33, thereby preventing the spray arm 33 from tilting when switching between the first position and the second position.

[0078] For example, see Fig.12 In some embodiments of the present application, the spray arm 33 may further include a mounting portion 334, which extends toward the abutment plate 34. The elastic member may include a spring 36, which is sleeved on the mounting portion 334. The spray arm 33 can also stably switch between the first position and the second position under the action of the spring 36.

[0079] Fig.13 The third structural diagram of the spray arm 33 provided in the embodiment of the present application is shown. Fig.13 In some embodiments of the present application, the spray arm 33 includes a first half arm 335 and a second half arm 336 connected to the first half arm 335, and the multiple spray holes 332 include multiple first spray holes 3321 and multiple second spray holes 3322, the first spray holes 3321 are arranged on the first half arm 335, and the second spray holes 3322 are arranged on the second half arm 336.

[0080] The orientation of the first spray hole 3321 is different from that of the second spray hole 3322 , so that a driving force for driving the spray arm 33 to rotate is generated when the washing water is sprayed out.

[0081] Exemplarily, the first spray hole is opened in a first direction (ie, inward direction perpendicular to the paper plane), and the second spray hole is opened in a second direction (ie, outward direction perpendicular to the paper plane), so that the spray arm 33 can obtain a driving force for counterclockwise rotation.

[0082] Exemplarily, the first spray hole is opened toward the second direction, and the second spray hole is opened toward the first direction, so that the spray arm 33 can obtain a driving force to rotate in a clockwise direction.

[0083] In some embodiments of the present application, along the clockwise direction, the orientations of two adjacent first spray holes 3321 have a preset angle, and the orientations of two adjacent second spray holes 3322 have a preset angle, which is beneficial for the first half-arm 335 and the second half-arm 336 to obtain the maximum rotational driving force.

[0084] Fig.14 The second schematic diagram of the overall structure of the dishwasher provided in the embodiment of the present application is shown. Fig.14 In some embodiments of the present application, the dishwasher body 10 further includes a support beam 12, which is disposed in the inner cavity 11 of the dishwasher 1 and extends along the height direction of the dishwasher 1. There are multiple spray assemblies 30, and the multiple spray assemblies 30 are connected to the support beam 12 and are spaced apart along the height direction of the dishwasher 1, so as to comprehensively clean the bowl basket and achieve a better washing effect.

[0085] Combined with reference Figure 2 and Fig.14 In some embodiments of the present application, the spray assembly 30 may also include a washing motor 40 and a water pipe. The washing motor 40 is used to provide spraying power. One end of the water pipe is connected to the washing motor 40, and the other end of the water pipe is connected to multiple spray pipes 31. In this way, the washing motor 40 can pump washing water into the water pipe and divert it to each spray pipe 31 through the water pipe.

[0088] It should be noted that the spray assembly 30 provided in the present application may not be limited to the dishwasher 1, but may also be applicable to scenarios requiring spraying operations such as fermentation cabinets or drones spraying pesticides.

[0089] In summary, the dishwasher provided in this application mainly has the following advantages:

[0090] (1) The spray arm 33 of the present application is provided with a pre-drain hole on one side facing the abutment plate 34 and can move along the axial direction of the connecting shaft 32. When the spray arm 33 is in the first position, the abutment plate 34 abuts against the pre-drain hole 333 to prevent the washing water in the water storage chamber 331 from leaking downward. When the spray arm 33 is in the second position, the abutment plate 34 and the pre-drain hole 333 are separated from each other to form a drainage gap. The residual washing water can be drained in advance through the drainage gap, preventing the residual washing water from spilling onto the dried dishes or outside the dishwasher 1 when the user pulls out the bowl basket, thereby improving the actual user experience.

[0091] (2) The present application utilizes the elastic potential energy of the elastic member, combined with the different gravitational potential energies of the spray arm 33 of the dishwasher 1 in the washing stage and the drying stage, to conveniently realize the switching of the spray arm 33 between the first position and the second position.

[0092] (3) After the drainage gap between the abutment plate 34 and the pre-drain port 333 is formed, as the washing water in the water storage chamber 331 is discharged, the difference between the elastic potential energy of the elastic member and the gravitational potential energy of the spray arm 33 continues to increase, making the above-mentioned drainage gap larger, accelerating the outflow of washing water, forming a positive feedback regulation, and realizing the rapid emptying of residual washing water.
